▼ Exchanging and integrating data that belong to worlds of different vocabularies are two prominent problems in the database literature. While data coordination deals with managing and integrating data between autonomous yet related sources with possibly distinct vocabularies, data exchange is defined as the problem of extracting data from a source and materializing it in an independent target to conform to the target schema. These two problems, however, have never been studied in a unified setting which allows both the exchange of the data as well as the coordination of different vocabularies between different sources. Our thesis shows that such a unified setting exhibits data integration capabilities that are beyond the ones provided by data exchange and data coordination separately. In this thesis, we propose a new setting – called DSE, for Data Sharing and Exchange – which allows the exchange of data between independent source and target applications that possess independent schemas, as well as independent yet related domains of constants. To facilitate this type of exchange, we extend the source-to-target dependencies used in the ordinary data exchange setting which allow the association between the source and the target at the schema level, with the mapping table construct introduced in the classical data coordination setting which defines the association between the source and the target at the instance level. A mapping table construct defines for each source element, the set of associated (or corresponding) elements in the domain of the target. The semantics of this association relationship between source and target elements change with different requirements of different applications. Ordinary DE settings can represent DSE settings; however, we show that there exist DSE settings with particular semantics of related values in mapping tables where DE is not the best exchange solution to adopt. The thesis introduces two DSE settings with such a property. We call the first DSE with unique identity semantics. The semantics of a mapping table in this DSE setting specifies that each source element should be uniquely mapped to at least one target element that is associated with it in the mapping table.
ii In this setting, classical DE is one method to perform a data exchange; however, it is not the best method to adopt, since it can not represent exchange applications, that require – as DC applications – to compute both portions as well as complete sets of certain answers for conjunctive queries. In addition, we show that adopting known DE universal solutions as semantics for such DSE settings is not the best in terms of efficiency when computing certain answers for conjunctive queries. The second DSE setting that the thesis introduces with the same property is called DSE with equality semantics. This setting captures interesting meaning of related data in a mapping table. Such semantics impose that each source element in a mapping table is related to a target element only if both elements are equivalent (i.e they have the…

▼ The Design Structure Matrix model has facilitated the study of design structure and architectural
complexity of complex systems by analyzing dependencies between system’s elements. There exists examples and applications of different DSM types highlighting real world engineered systems in the literature provided by the researchers and authors. Unfortunately, there does not exist any specialized digital format that can make those DSM examples data accessible to public for further analysis. Having said this, in this thesis, we propose a Data Exchange file format suitable for Design Structure Matrix (DSM) models. The DSM Data Exchange (DSMDE) file format can be considered as a common file format that supports DSM data to be exchanged in an organized manner. Thus, we (more) formally propose an extension to an existing “appropriate” exchange file format instead of creating a new one. We choose “Matrix Market (MM) file format” for extension to store DSM information. As DSM techniques are playing a vital role to model and analyze complex network in the area of product development, we believe that our DSMDE file format will contribute to establish a common standard of exchanging DSM data to the researchers
and developers.

▼ Network coding is a novel technique that has a significant potential to improve throughput, robustness and security of both wireless and wireline networks. With network coding the intermediate nodes in the network have the capability to combine multiple incoming packets and forward the resulting packets over their outgoing links. This technique has a significant advantage over traditional methods such as forwarding and duplication of packets. Recently, the network coding technique has attracted a significant interest from the research community.
In this dissertation, we address a number of wireless network coding problems. In particular, our work focuses on the Cooperative
Data Exchange (CDE), one of the central problems in wireless network coding. In Cooperative
Data Exchange, a group of clients that have a prior side information about a set of packets use a shared broadcast channel to recover the missing packets from the set. We focus on different variations of the problem, including
data exchange in the presence of passive and active adversaries,
data exchange subject to deadlines, as well as serving clients of different priority classes. For each variation, we analyze the complexity of the problem and present exact or approximation algorithms for its solution. We show that this set of problem is very rich and has deep connections to different areas of coding theory, algebraic geometry, and information theory.

▼ Scania is a Swedish automotive manufacturer for heavy vehicles and engines. It also offers transport solutions and long term commitment for customers. In today's Scania, a modular system provides a huge variety of specifications to meet varying dramatic needs for different customers. In order to be able to meet the diverse requirements of customers, modular approach with the support of reusable components is used to increase the efficiency of designing different products.
To customize both product development and product design, computer aided design(CAD) is used to support the process of design and design documentation. "CATIA" is a multi-platform CAD software and "ENOVIA" is a product modeling product offers product database management for virtual model design into CATIA, both "CATIA" and "ENOVIA" are developed by the French company Dassault Systemes are chosen by Scania to support its product development.
The modular system approach requires the system support for product structure, which is managed by a mainframe called SPECTRA.
The thesis project is mainly about system designing a new module which takes the responsibility for exchanging information between SPECTRA and ENOVIA. In more detail, the new component is to perform a mapping of data in SPECTRA format into a format which ENOVIA can import. The mapping module has several interfaces with other applications in the system. JavaMigrator provides the environment to import data from the mainframe and transfer the data into the module and finally output the expected data format into ENOVIA.
To achieve this purpose, several possible solutions were proposed and several methods were tried. Since an in-house developed CAA-module is highly preferred by Scania, the new mapping component will finally be designed into two separate modules, the first part converts the XML extracted from SPECTRA into an intermediate format and the second part is designed to convert the intermediate file into the expected target file.
The intermediate file is required, since the format is independent of changes in both SPECTRA and ENOVIA. Furthermore, it is flexible and less complex to maintain than direct mapping from exported XML to ENOVIA.
The report focuses on five parts, background, project specification, methodology, implementation, result and future work.

▼ Ubiquitous mobile phones have turned into sensing devices that are capable of capturing detailed information about people's surrounding environment, activities, physical state. This development leads to a huge and diverse collection of fine-grained data, which creates unique mining opportunities that benefit society as a whole. Of particular importance is individuals' trajectory data, i.e., a set of time stamped location points, which can be analysed to improve the performance in many fields, from traffic management and urban planning to natural crisis management. However, privacy concerns place a great impediment to trajectory data release: trajectory data not only reveals individuals' whereabouts over time, it also discloses a high level of detail regarding their lifestyle, i.e., where they live and work, where they like to go for shopping and eating out. Many studies aim to address the issue of trajectory privacy through exploring what should be shared, how, when and where it should be shared. Most such proposed privacy preserving solutions though, distort original data unnecessarily, and hence, degrade data utility. Data utility is key to useful analytics and high-quality service delivery which results in a win-win situation to both individuals and third parties. In this work, we present the utility loss of trajectory obfuscation techniques and differentially private trajectory releases and we propose effective inference attacks against these models. We also propose a utility-aware algorithm for protecting the sensitive stop points of a trajectory through spatiotemporal perturbation.

▼ An individual’s choice to share or have control of the sharing or withholding of their personal health information is one of the most significant public policy challenges associated with electronic information exchange. There were four aims of this study. First, to describe predictors of health data sharing preferences of consumers. Second, to test a hypothesized path diagram to understand the strength, path, and direction of relationships between and among the constructs of information privacy, data security, data sharing preferences, and consumer-mediated exchange (C-ME). Third, to create a theoretical model. Fourth, to make recommendations describing data governance structures needed for personally identifiable information in consumer-mediated data management. Study findings indicate two levels of health data sharing preferences exist (a) sharing between providers and (b) personal access to health information. The theoretical model showed data security and information privacy have a positive, direct relationship on consumer health data sharing preferences with respect to the types of data and mechanisms used to share personally identifiable health information. Results of this study were used to propose an integrated system approach to design, management, and control of consumer-mediated data management.

▼ Our thesis investigates a mechanism for representing schema mapping by tabular forms and checking utility of the new representation.
Schema mapping is a high-level specification that describes the relationship between two database schemas. Schema mappings constitute essential building blocks of data integration, data exchange and peer-to-peer data sharing systems. Global-and-local-as-view (GLAV) is one of the approaches for specifying the schema mappings. Tableaux are used for expressing queries and functional dependencies on a single database in a tabular form. In our thesis, we first introduce a tabular representation of GLAV mappings. We find that this tabular representation helps to solve many mapping-related algorithmic and semantic problems. For example, a well-known problem is to find the minimal instance of the target schema for a given instance of the source schema and a set of mappings between the source and the target schema. Second, we show that our proposed tabular mapping can be used as an operator on an instance of the source schema to produce an instance of the target schema which is `minimal' and `most general' in nature. There exists a tableaux-based mechanism for finding equivalence of two queries. Third, we extend that mechanism for deducing equivalence between two schema mappings using their corresponding tabular representations. Sometimes, there exist redundant conjuncts in a schema mapping which causes data exchange, data integration and data sharing operations more time consuming. Fourth, we present an algorithm that utilizes the tabular representations for reducing number of constraints in the schema mappings. At present, either schema-level mappings or data-level mappings are used for data sharing purposes. Fifth, we introduce and give the semantics of bi-level mapping that combines the schema-level and data-level mappings. We also show that bi-level mappings are more effective for data sharing systems. Finally, we implemented our algorithms and developed a software prototype to evaluate our proposed strategies.

▼ Product master data (PMD) can be defined as a set of data that represents a selection of characteristics and aspects of its accompanying physical product. For several reasons, these data sets are increasingly exchanged between organizations within supply chains. Although this process is traditionally often supported by non-automated technologies such as Excel spreadsheet, telephone, email, and fax, the adoption of data pools is on the rise. These inter-organizational systems allow the data supplying party to publish a product’s master data set in one centralized system after which it can be accessed by all subscribed data recipients.

▼ In the current global business environment the
focus is on increased quality and reduced cycle times. In spite of
advanced manufacturing and automation technology, the link between
CAD and CAM is still not as integrated as desired. Although in most
circumstances CAD data can be processed within the CIM environment
by integrated software components to produce information like
manufacturing data, assembly data, etc., there are a significant
number of cases where an external CAD resource needs to be
processed for further integration with CAM. In this context, this
research work aims at developing a novel approach to integrate CAD
and CAM, specifically for the rotary parts drawn in any CAD
environment and finally to generate a CNC part program for the
same. The proposed system is developed in four phases. The first
phase involves, getting a CAD model of 2D upper half profile of the
required component drawn in any CAD environment and converted to
DXF data structure. The second phase is about Data extraction
system which is used to extract the useful geometrical data
pertaining to the component from its corresponding DXF file. The
third phase, Feature Recognition system, is used to organize the
data extracted from the DXF file and present the same in the form
of a more meaningful data, called as design features, using
syntactic pattern recognition technique. Feature Mapping is
performed to map the design features in to thecorresponding
predefined manufacturing features. Rule-based process sequencing is
performed to sequence the machining operations. The final phase
involves the generation of CNC part Program. Several algorithms
were developed to translate the design data to the corresponding
CNC codes. A software program in ?C? is developed for extraction of
the feature data from the related DXF file and for the generation
of the part program. The output of the program is given in the form
of text files. Based on the proposed novel approach simulation runs
are carried out and the results were found to be
satisfactory.

▼ This study examines the comparative magnitude of disturbances in intraday
data for
exchange traded foreign
exchange (FX) options. An in-depth time series analysis on the frequency and extent of discrepancies in the disturbances is conducted. The purpose of this study is twofold. First, using intraday
data and trading volume, this study attempts to determine whether both put-call parity and lower boundary conditions consistently hold for
exchange traded options written on U.S. dollar denominated options on the Euro trading on the Philadelphia Stock
Exchange (PHLX). Second, this study attempts to investigate the magnitude of any discrepancies that may exist due to a temporary cessation of either put-call parity or lower boundary conditions. Intraday (tick-by-tick) bid prices, ask prices, and trading volume on U.S. dollar denominated European style call options and put options on the Euro are obtained. Option
data is collected through a Structured Query Language (SQL) request from the Bloomberg database. Corresponding tick-by-tick spot rates for the underlying
exchange rate are obtained for the same time period. Tick-by-tick 3-month Treasury bill rates are obtained to for use as the relevant risk-free interest rate. The primary
data set spans an approximate one month period from 11/1/2011 to 12/6/2011. Call and option pricing
data for near-the-money exercise prices are obtained for options expiring in December 2011, January 2012, February 2012, March 2012, June 2012, and September 2012. A total of 7,212 ticks (minutes) are analyzed for the conversion strategy and 7,209 ticks are analyzed for the reversal strategy. The
data is structured into an unbalanced panel
data set (cross-sectional time series
data) using put-call pairs as the cross sectional units and ticks as the time-series unit. To test the efficiency of the foreign
exchange options market, lower boundary and put-call parity conditions were tested on tick-by-tick currency option
data. Analysis shows that lower boundary conditions hold for the overwhelming majority of options, with less than 0.0001% of violations for the observed options. A more detailed econometric analysis was prepared to test the put-call parity condition for currency options. A fixed effects model specification is used to describe the put-call parity relationship. Based on the analysis, it is possible to obtain arbitrage profits in the short run through the use of either a conversion or reversal strategy even after accounting for transaction costs. Taking the first differences of the variables resulted in a model with stationary variables and statistically significant estimators. The inclusion of dummy variables for moneyness did not add significant explanatory power to the deterministic put-call parity relationship. For both first differences of conversion and reversal strategies, the large t-statistics for the slope coefficients and intercept terms indicate a rejection of the null hypothesis, H0: λ0 = 0 and λ1 = 1 after adjusting for standard error. This implies that once…

▼ Water management is becoming increasingly important in the world. Population growth, climate change, and increasing demands placed on infrastructure call for a smart and standardized approach. The data needs to stay at the source and sharing information in a more efficient way is becoming increasingly important. To make this possible in the water sector a platform is needed to facilitate the exchange of information. This platform allows for keeping data at the source, which can then be accessed all over the world. The data exchange will become possible when the platform works according the right standards. An integrated model based on existing standards is one of the first steps in achieving better communication and interoperability. The research goal is to to design a well defined information model based on standards that will be optimal for implementation in a information infrastructure within the water sector to make the 1D time series data exchange easier. This is done by a research to the existing standards and there capabilities. The standards are described and from their background an information a model is created to illustrate in one overview the relations between these standards on several levels. To create one Hydrological TimeSeries Stan- dard Based Information Model (HydroTS-SBIM) the international standards that are most relevant are selected and reviewed; ISO 19156 O&M, OGC Timeseries Profile of O&M and WaterML 2.0: Part 1- Timeseries. This is done to get a clear and complete HydroTS-SBIM that gives an accurate insight on both the positive and negative aspects of the existing standards, and will show in one information model the possible relation between them. For now the standards cannot be merged into one complete model due to the inconsistencies among the standards. Therefore the HydroTS-SBIM 2.0 is created to illustrate these inconsistencies and complications on each level. To create an HydroTS-SBIM thorough research has been done, including interviews with highly educated specialists within the fields of data standardization, governance and the water sector. A survey was used as feedback for the creation of a demo version of the proposed solution, called the Packet Plan. The Packet Plan is an step-by-step approach to the standards. To show the use of the packets, the core packet is developed which is called core packet A. It illustrates that there is no need to implement the total standard in all its richness at once to be able to share data, instead it presents a model with the concept of compact packets. This is a time efficient process where the implementation of the standard will be in parts, leading to less information at once but divided over the packets. The user will only get the required information for the specific part the user needs at that time, resulting in an easier and more time efficient data exchange.

▼ Emotion coregulation occurs when dyadic partners mutually, reciprocally, and bi-directionally influence each other’s emotional experience (Cole, Teti, & Zahn-Waxler, 2003; Tronick, 1989). Coregulatory processes influence the development of child self-regulation skills and thus have mental health implications (Cole & Hall, 2008). Most research examining emotion coregulation has involved infants, but more recently its importance during other periods has been considered (e.g. Feng, Shaw, Skuban, & Lane, 2007). The proposed study focuses on toddlerhood because it is marked by rapid developmental changes, including heightened incidence of child assertion of goals that conflict with parental goals. How these developmental changes contribute to changes in coregulatory processes is not well understood.
This thesis assesses the degree of coregulation of emotion in mother-toddler interaction in a context that optimizes participants having divergent goals: over an 8 minute period toddlers waited to open a gift until mothers completed work. Employing second-by-second coding, the thesis examined the overall number of seconds and percentage of time in which toddlers and mothers expressed emotions and the number of times their task orientation and emotions changed (i.e., shifted from one emotion to another, or decreased or increased in expression intensity) during the task. We aimed to establish the frequency of (1) child emotion and behavior changes as precursors to mothers’ orienting toward the child, and (2) change in expression in one interaction partner occurring after a change in the other while the two were oriented toward each other.
Results indicated that mothers oriented toward toddlers for about 20% of task time. They were more expressive overall and shifted their expressions more when oriented toward their toddlers than when working. Toddlers expressed more intense emotions, overall happiness, and focus on the gift, and showed fewer shifts in emotion expression, when mothers were oriented
toward them compared to when mothers worked.
When we examined precursors to mothers’ orienting toward toddlers, we found that changes in toddler anger expressions and focus on the gift were more likely to prompt the mother to orient toward their toddler than shifts in happy expressions. Once oriented toward toddlers, mothers expressed anger infrequently (about 10% of the time). Mothers’ anger expressions evoked toddler anger expressions. However, toddler anger expressions were not as evocative for mothers, who were more likely to stop, rather than start, expressing anger after toddlers expressed anger.
Results are discussed in terms of providing evidence for mutual, reciprocal, and bi-directional influences of mother-toddler emotion expressions during a frustrating task in which dyadic partners have competing goals. The thesis provides a rich descriptive picture of the emotional nature of the challenging wait, and demonstrates how mothers and children influence each other’s emotional expressions over the course of the task at a…

▼ Network performance maps can be used as a tool to predict network conditions at a given location, based on previous measurements at that location. By using measurement data from other users in similar locations, these predictions can be significantly improved. This thesis looks into the accuracy of predictions when using different approaches to distribute this data between users, we compare the accuracy of predictions achieved by using a central server containing all known measurements to the accuracy achieved when using a crowd-based approach with opportunistic exchanges between users. Using data-driven simulations, this thesis also compares and evaluates the impact of using different exchange policies. Based on these simulations we conclude which of the exchange policies provides the most accurate predictions.

▼ ããRecommendation techniques are developed to uncover usersâ real needs among large volume of information. Recommender systems help us filter information and present those similar to our tastes. As wireless technology develops and mobile devices become more and more powerful, new recommender systems appear to adapt to new implementation environment. We focus on travel recommender systems implemented in a mobile P2P environment using collaborative filtering recommendation algorithms which intend to provide real-time suggestions to travelers when they are on the move. Using the concept of incorporating other travelersâ suggestions to the next attraction, we let users
exchange their ratings toward visited attractions and use these ratings as a basis of recommendation.
ããWe proposed six
data exchange algorithms for travelers to
exchange their ratings. The proposed methods were experimented in the homogeneous and heterogeneous environment. The experimental results show that the proposed
data exchange methods have better recommendation hit ratio than content-based recommendation methods and better performance compared with other methods only using ratings of users when they meet face-to-face. Finally, all methods are compared and evaluated. An optimal method should be able to strike a balance between algorithm performance and the amount of
data communication.

▼ Despite recommender systems being useful, for some applications it is hard to accumulate all the required information needed for the recommendation. In today‟s ubiquitous environment, mobile devices with different characteristics are widely available. Our work focuses on the recommendation service built on mobile environment to support tourists‟ traveling need. When tourists visit a new attraction, their recommender systems can
exchange data with the attraction system to help obtain rating information of people with similar tastes. Such asynchronous rating
exchange mechanisms allow a tourist to receive ratings from other people even though they may not collocate at the same time.
We proposed four
data exchange methods between a user and an attraction system. Our recommendation mechanism incorporates other users‟ opinions to provide recommendations once the user has collected enough ratings. Every method is compared under four conditions which attraction systems carry different amount of existing
data. Then we compare these methods under different amount of existing rating
data and shed the light on their advantages and disadvantages. Finally, we compare our proposed asynchronous methods with other synchronous
data exchange methods proposed previously.

▼ The thesis focuses on finding solutions to major
exchange rate puzzles, which were discussed in detail by Obstfeld
and Rogoff (2000). The first puzzle is the purchasing power parity
puzzle. The first version of the latter puzzle is concerned with
whether a real
exchange rate reverts in the mean. To resolve the
puzzle in the context of Southern African Development Community
countries, the thesis uses Bayesian unit root testing and nonlinear
nonstationarity tests associated with the smooth transition
autoregressive family of models. According to Bayesian unit root
test results, the nonstationarity hypothesis received small
posterior probability relative to other hypotheses. In this
setting, the Bayesian results strongly supported the hypothesis
that all the real
exchange rates were trend-stationary
autoregressive processes. However, it should be pointed out that
Ahking (2004) has found these tests to be biased toward trend
stationarity. Nonlinear nonstationarity tests presented evidence
that four out of ten of SADC’s real
exchange rates could be
regarded as nonlinear globally ergodic processes, while others
could be considered random walks. The thesis relies on
local-to-unity asymptotic theory and Rossi (2005a) to deal with the
half-life version of the PPP puzzle. The half-life version is that
a high degree of
exchange rate volatility is generally associated
with an implausibly slow speed of mean reversion. Depending on the
robustness of the methods used, empirical evidence points to
several half-lives of less than 36 months, but the confidence
intervals of half-life deviations from PPP are found in all cases,
as in Rossi’s work, to be too wide to be informative enough to
resolve the puzzle. In addition, the thesis undertakes Hinich and
Chong (2007) class tests of fractional integration to ensure that a
long memory process is not mistaken for a nonstationary process in
finding solutions to the PPP puzzle. The results show that at 1 per
cent and 5 per cent significance levels, the real
exchange rates
associated with South Africa, Mauritius and Swaziland are not
fractionally integrated. Tanzania’s real
exchange rate was found to
be stationary-fractionally integrated but with the antipersistence
property. Other currencies were found to be
nonstationary-fractionally integrated. The third puzzle is the
exchange rate determination puzzle, which is as follows: In the
short run there seems to be no reliable determinants of
exchange
rates. The thesis relies on the market microstructure approach to
find the determinants of South Africa’s
exchange rate. In this
context, the thesis utilises autoregressive distributed lag model
of cointegration to identify the fundamental and non-fundamental
determinants of the rand/dollar
exchange rate. The main
contribution of the thesis to the economic literature is the usage
of newly developed methods in an attempt to resolve the
above-mentioned puzzles.

▼ We propose a framework for semi-automatically
verifying relational database schema mappings for data exchange.
Schema mappings for data exchange formally describe how to move
data between a source and target database. State-of-the-art schema
mapping tools propose several mappings, but require user
intervention to determine their semantic correctness. For this, the
user must understand the domain the schemas represent and the
meanings of individual schema elements in relation to the domain.
Our framework eases the task of understanding the domain and
schemas and performs preliminary mapping verification. We use a
readable, expressive, and formal conceptual model - a domain
ontology - to model the source and target schema domain. We model
the schema semantics by annotating schema elements with ontology
elements. Our mapping verification algorithm rewrites mappings as
statements in terms of the ontology, and uses a reasoner to check
that the statements are entailed by the ontology.

▼ An automated on-line ion
exchange trace enrichment system has
been developed to improve the detection limits of flame atomic
absorption (AA) spectrophotometry in the determination of trace
metals in natural waters. The sample solution is passed through a
column of Chelex-100 chelating resin by a carrier buffer stream
delivered from a constant flow pump. Trace metal ions retained by
the Chelex-100 resin in the column are subsequently eluted off the
column using complexing agents such as cysteine and EDTA. The
variables that affect the performance of the system are studied. The
detection limits of the system with flame AA detection are 0.09 μg/L
for Cu and Cd and 0.08 μg/L for Mn with a 10-mL sample loop.
The trace enrichment system has also been expanded to an
automated two-column ion
exchange system to study the speciation of
trace metals in natural waters. In the two-column system, the sample
solution is passed sequentially through a column of Chelex-100 resin
and a column of AG MP-1 macroporous anion resin. The Chelex-100
column retains free metal ions and metal ions dissociated from labile
metal complexes. The AG MP-1 column retains anionic non-labile metal
complexes and metals strongly associated with negatively charged
organic matter such as humic acid. The dissolved metal species are
classified into three fractions by the proposed measurement scheme.
The variables that affect the results obtained by the two-column
system are studied using model complexing agents. The measurement
scheme is shown to be rapid and simple (about 10 min per sample with
a 10-mL sample loop) and is used to determine the speciation of
Cu(II), Cd(II) and Zn(II) in natural water samples.
The two-column ion
exchange system is a versatile tool to study
the trace metal complexation in natural waters. The system is used
to determine the trace metal complexing capacity and conditional
stability constants of synthetic ligands and ligands in natural
waters and to study the dissociation kinetics of trace metal
complexes in natural waters. The average Cu(II) complexing capacity
of a Willamette River water sample is found to be about 4 μM and the
conditional stability constant of Cu(II) complexes is about 10⁷ at
pH 7. The apparent 1st -order dissociation rate constant of Cu-humate
complexes is determined to be about 0.3 s⁻¹ at pH 6.5.

▼ With an increasing demand for building energy performance, energy audits are being adopted more often by commercial building owners to determine the feasibility of building retrofits. The initial step of energy audits is to collect the building energy use
data. The
data collection supports the development of the baseline energy modeling, which is used to determine potential energy savings of potential energy conservation measures. However, there are few standards to define the
data collection for energy audits, which makes it difficult to perform an energy audit at the initial stage and to leverage the information
exchange to benefit downstream energy modeling. This research evaluated the information
exchange between energy auditing
data collection and the computerized energy modeling based on the content analysis of current public energy audit
data collection templates and widely used energy modeling software input. The average
data alignment between the two steps was only 31%. The inconsistent level of detail of the information was suggested to be one of the reasons for the low alignment of
data.
To address the issue, a Level 1 or walk-through energy audit
data collection and energy modeling input protocol was developed to define the information
exchange scope and
data transfer requirements. The defining of energy audit
data collection scope and processes for
data collection was analyzed. The energy simulation tool input was analyzed based on the categorization of energy
data level of detail. The energy modeling input feedback model was also presented to evaluate the information
exchange. A case study was conducted to evaluate the protocol. Results indicated that the protocol supports the information
exchange in terms of the accuracy of the energy model and the level of effort to develop the model.

▼ The way people meet each other is usually face to face. Meanwhile, the way people maintain their contacts is mostly through social media. This results in a gap of translating a handshake into a digital connection. Shake-On is a start-up that has come up with an answer by means of a smart bracelet. Their aim is to wirelessly exchange contact details between users wearing the bracelet. This exchange is triggered by the most common human gesture people use when introducing themselves: the handshake. This thesis will overcome two major challenges for Shake-On. First, no general pattern recognition method can be applied to detect handshakes. This is caused by the fact that handshakes gestures show large variations among individual persons. Second, the system should be robust to multiple handshakes happening concurrently. This applies to the scenario of more than two people shaking hands while standing close to each other. Contact details should only be exchanged between people that are handshaking, which requires handshake matching. Again, large variations in `handshaking style' make it a cumbersome task to identify matching handshakes. This thesis proposes a two-fold solution to address the above-mentioned challenges. The first part includes handshake detection, using new features for pattern recognition that are tailored to handshaking recognizing. The second part proposes a new method to perform handshake matching that overcomes the shortcomings of existing solutions. The work done in this thesis has led to the following results: 1. The developed detection method takes into account limited resources and is therefore suitable for implementation on a smart bracelet. Moreover, it shows similar performance as the state-of-the-art solutions, namely an accuracy of 95%. In contrast to existing solutions using 6 stochastic features, our solution uses 4 computationally lightweight features. 2.Being the first of its kind, the matching method proposes a novel technique that maps handshakes to an abstract binary format. This format is called peakmaps. Because it eliminates personal handshaking style, peakmaps result in a pairing accuracy of 80% compared to 24% using basic cross correlation.

▼ Automatic Exchange of Information (AEOI) standard is an initiative to eradicate offshore tax evasion using utilizing the advancement of technology so that each participating country can perform cross border information sharing. However, challenges arise especially for the developing countries regarding the fulfillment of needed IT infrastructure enabling the automated reporting process. To date, little is found in the literature related to the empirical study on the types of IT infrastructure that support the reporting process. Therefore, in this research, we aim to investigate the forms of IT infrastructure and its governance that could enable the reporting for the AEOI purpose, while also exploring the determinants influencing the selected approach. The objective is realized by developing an analytical framework that helps in analyzing the problem and apply it to a case study in two countries which is the Netherlands and Indonesia. In the end, our research signifies two different types of IT infrastructure and governance approach, in which there is no superior or the best-fit for the implementation because the choice of infrastructure will depend on the contextual factors that affect the needed requirements.

▼ Although geotechnical information is obtained from
rather costly drilling and laboratory operations, they are poorly
documented and curated, due to lack of adoptable standards for
data
handling.; In this PhD dissertation proposal, first geotechnical
community and
data will be reviewed. Then, evolution of
geotechnical
data release within the community is studied. Based on
the advantages and shortcomings of past efforts and the community
specific needs, a requirement list for
data exchange format is
created. After detail analysis of AGS format for geotechnical
data,
an eXtensible Markup Language (XML)-based
data organization is
proposed. The eXtensible AGS (XAGS)
data format is discussed in
detail. XAGS is validated by examples of
data generation and
modification,
data validation,
data exchange, and archive and
distribution via World Wide Web. To show the improvements of the
new
data exchange format over the previous formats, the proposed
data format is evaluated by comparing its capabilities with the
requirement list developed early in the study. At the end, a
metadata model has been developed for documenting the
data sets
generated by experiment and simulation processes. The metadata
model has an object-oriented structure developed using web ontology
tools and expressible in XML schemas. The usefulness of the
metadata model is demonstrated by generating automatic
data reports
and exchanging
data sets with complete documentations. The metadata
model for experimental research can be used as a guideline to
develop metadata model for geotechnical information that are not
well-documented.

▼ Transit systems are an integral part of surface transportation systems. A connected vehicle technology (CVT) supported transit system will assist the users to manage trips both dynamically and efficiently. The primary focus of this research is to develop and evaluate the performance of a secure, scalable, and resilient
data exchange framework. In the developed
data exchange framework, a new
data analytics layer, named Transit Cloud, is used to receive
data from different sources, and send it to different users for a Dynamic Transit Operations (DTO) application. The DTO application allows the transit users to request trip information and obtain itineraries, using their personal information devices, (e.g., cell phone), and provides dynamic routing and scheduling information to the transit operators. A case study was conducted to investigate the effectiveness of the developed
data exchange framework, by comparing the framework with the USDOT recommended
data delivery delay requirements. This
data exchange framework was simulated in the CloudLab, a distributed cloud infrastructure, in which, the
data exchange delay for DTO was examined for different simulation scenarios, utilizing the synthetic
data generated from Connected Vehicle Reference Implementation Architecture (CVRIA) and Research
Data Exchange (RDE). Security, scalability, and resiliency of the developed
data exchange framework are illustrated in this thesis. The results from the simulation network reveal that the
data exchange delay satisfies the USDOT
data delivery delay requirements. This suggests that the developed secure, scalable, and resilient
data exchange framework, which is presented in this study, meets the application performance requirements. Thus, Transit Cloud is a more preferable alternative than the existing framework because of its added benefits in terms of security, scalability, and resiliency.

▼ An efficient and effective
data exchange
mechanism is indispensable for multi-disciplinary optimization
frameworks that provide a common working environment to increase
interdisciplinary interactions and reduces the design cycle time.
Some of the existing
data exchange mechanisms have been studied and
a new
data exchange mechanism has been implemented. The scope of
this work has been to develop two tools namely the Vector tool and
the Name-Value tool to handle
data in the form of one-dimensional
arrays and name-value pairs respectively. A
data caching algorithm
has also been implemented so that the two tools interoperate with
the help of adapters that translate

▼ The concept of grid computing has permeated all
areas of distributed computing, changing the way in which
distributed systems are designed, developed and implemented. At the
same time ‘geobrowsers’, such as Google Earth, NASA World Wind and
Virtual Earth, along with in-vehicle navigation, handheld GPS
devices and maps on mobile phones, have made interactive maps and
geographic information an everyday experience. Behind these maps
lies a wealth of spatial
data that is collated from a vast number
of different sources. A spatial
data infrastructure (SDI) aims to
make spatial
data from multiple sources available to as wide an
audience as possible. Current research indicates that, due to a
number of reasons,
data sharing in these SDIs is still not common.
This dissertation presents an analysis of the
data grid approach
for SDIs. Starting off, two imaginary scenarios spell out for the
first time how
data grids can be applied to enable the sharing of
address
data in an SDI. The work in this dissertation spans two
disciplines: Computer Science (CS) and Geographic Information
Science (GISc). A study of related work reveals that the
data grid
approach in SDIs is both a novel application for
data grids (CS),
as well as a novel technology in SDI environments (GISc), and this
dissertation advances mutual understanding between the two
disciplines. The novel evaluation framework for national address
databases in an SDI is used to evaluate existing information
federation models against the
data grid approach. This evaluation,
as well as an analysis of address
data in an SDI, confirms that
there are similarities between the
data grid approach and the
requirement for consolidated address
data in an SDI. The evaluation
further shows that where a large number of organizations are
involved, such as for a national address database, and where there
is a lack of a single organization tasked with the management of a
national address database, the
data grid is an attractive
alternative to other models. The Compartimos (Spanish for ‘we
share’) reference model was developed to identify the components
with their capabilities and relationships that are required to
grid-enable address
data sharing in an SDI. The definition of an
address in the broader sense (i.e. not only for postal delivery),
the notion of an address as a reference and the definition of an
addressing system and its comparison to a spatial reference system
contribute towards the understanding of what an address is. A novel
address
data model shows that it is possible to design a
data model
for sharing and
exchange of address
data, despite diverse
addressing systems and without impacting on, or interfering with,
local laws for address allocation. The analysis in this
dissertation confirms the need for standardization of domain
specific geographic information, such as address
data, and their
associated services in order to integrate

heterogeneous sources. In conclusion, results are presented and

▼ North Central Nicaragua has long been on the fringes of the researched world and this region is still largely underrepresented in discourses on Central American archaeology. These have traditionally put the emphasis on defining ethnic territories and boundaries across the isthmus, often obscuring local diversity. The existing knowledge on the pre-Conquest societies of North Central Nicaragua rely heavily on linguistic sources and biased colonial accounts. An archaeological effort to understand the pre-Conquest past of the region would not only contribute to the writing of local history, but also contribute to archaeological discussions on an interregional scale.
Most of the archaeological
data available for the Matagalpa and Jinotega departments are found in unpublished survey reports. These have been largely disregarded due to the non-systematic survey strategies used and lacks in a chronological understanding of the archaeological sites and finds. This thesis adopts a visual GIS approach that makes use of these
data sources, in order to combine existing survey
data and explore the pre-Conquest past in the Matagalpa and Jinotega departments of North Central Nicaragua. A flexible framework is used to analyse the survey
data, accounting for its limitations and considering the particularly variable environmental zones that characterise this region. Considering different models of zonal complementarity and interregional
exchange, the visual analysis seeks to gain an understanding of pre-Conquest interzonal interaction and
exchange in the research area.
The analysis reveals different patterns of interzonal interaction. Distributions of movable finds penetrate different environmental zones, indicating
exchange between groups occupying different environmental zones. Finds linked to interregional networks are found in differing degrees of diversity in different parts of the research area, suggesting differing degrees of centrality and access to goods from outside regions. The available
data supports interregional down-the-line trade models taking place in an environmentally and most likely also socially and culturally heterogeneous landscape.
This thesis contributes to closing a knowledge gap on the pre-Conquest past both on a local and interregional scale. Combining existing archaeological
data helps archaeology to participate more effectively in current discourses about pre-Conquest North Central Nicaragua. Interregionally, this thesis contributes by presenting a comprehensive
data exploration in an underrepresented region through an environmental and geographical perspective. This perspective helps seeking new avenues in Central American archaeology that allow the consideration of local diversity without losing sight on interregional dynamics.

▼ Companies and governments use information technology standards to conduct
data exchange, the concept being called Business to Government (B2G)
data exchange. Companies use these standards to report their financial and business
data to the government and governments collect these
data for regulatory purposes. This research analyses two such competing
data standards EDIFACT and XBRL in the context of B2G
data exchange in India. Both the standards have their own set of supporters (regulators and firms) due to which it is uncertain which standard will become the dominant standard in future. Therefore, it is important for standard supporters to identify and leverage factors that could increase the likelihood of dominance of these standards. This is because, implementation of such
data standards firstly requires major changes to be made to the existing Information and Communication Technology (ICT) infrastructures. Secondly, such decisions are costly and difficult to reverse. This research focuses on the factors that play a major role in the battle for dominance in the field of B2G
data exchange between EDIFACT and XBRL in India. Five phases were described in this research that the standards go through in their lifecycle when battling for dominance. These phases were designed using the framework of Suarez 2004 as a foundation [1]. To analyze the battle and identify the factors in a structured manner, this research was conducted in 3 main steps. Firstly, factors that were relevant in each phase for the battle between XBRL and EDIFACT were identified via an extensive literature search. This has resulted in a comprehensive list of 21 factors. The second step was primary
data collection to identify the most important factors that are crucial to XBRL and EDIFACT with the help of a questionnaire. 9 experts in the field of
data exchange standards answered the questionnaire.
Data collection and
data analysis were done using a Multi Criteria Decision Making (MCDM) method called the Best Worst Method. The third step was to calculate weights and establish importance of these factors for EDIFACT and XBRL using BWM. In conclusion, 12 factors are identified to be very crucial in the battle for dominance between EDIFACT and XBRL in B2G
data exchange in India. These are Availability of a more general standard and Collaborations in phase 1, technical Capabilities and diversity of network in phase 2, regulatory support, awareness of the standard, and, implementation costs and time in phase 3, infrastructure dependency, switching costs, trial-ability and observe-ability, intermediaries and Bandwagon effects in phase 4, and, the factor innovation capabilities in phase 5. Based on the progress that the standards have made till date, and the results of BWM, XBRL has better chances of becoming dominant in future. The results of this research have significant contributions in research and practical applications of standard battles. This research bridges the gap that exists in the literature between two different aspects of…

Knowledge Guided Non-Uniform Rational B-Spline (NURBS) for Supporting Design Intent in Computer Aided Design (CAD) Modeling.

▼ For many years, incompatible computer-aided design (CAD) packages that are based on Non-uniform Rational B-Spline (NURBS) technology carried out the exchange of models and data through either neutral file formats (IGES or STEP) or proprietary formats that have been accepted as quasi industry standards. Although it is the only available solution at the current time, the exchange process most often produces unsatisfactory results. Models that are impeccable in the original modeling system usually end up with gaps or intersections between surfaces on another incompatible system. Issues such as loss of information, change of data accuracy, inconsistent tolerance, and misinterpretation of the original design intent are a few examples of problems associated with migrating models between different CAD systems. While these issues and drawbacks are well known and cost the industry billions of dollars every year, a solution to eradicate problems from their sources has not been developed. Meanwhile, researchers along with the industries concerned with these issues have been trying to resolve such problems by finding means to repair the migrated models either manually or by using specialized software.
Designing in recent years is becoming more knowledge intensive and it is essential for NURBS to take its share of the ever increasing use of knowledge. NURBS are very powerful modeling tools and have become the de facto standard in modeling. If we stretch their strength and make them knowledge driven, benefits beyond current expectations can be achieved easily. This dissertation introduces knowledge guided NURBS with theoretical and practical foundations for supporting design intent capturing, retrieval, and exchange among dissimilar CAD systems. It shows that if NURBS entities are tagged with some knowledge, we can achieve seamless data exchange, increase robustness, and have more reliable computations, all of which are ultimate objectives many researchers in the field of CAD have been trying to accomplish for decades. Establishing relationships between a NURBS entity and its origin and destinations can aid with seamless CAD model migration. The type of the NURBS entity and the awareness of any irregularities can lead to more intelligent decisions on how to proceed with many computations to increase robustness and achieve a high level of reliability.
As a result, instead of having models that are hardly modifiable because of migrating raw numerical data in isolation, the knowledge driven migration process will produce models that are editable and preserve design intent. We have addressed the issues not only theoretically but also by developing a prototype system that can serve as a test bed. The developed system shows that a click of a button can regenerate a migrated model instead of repairing it, avoiding delay and corrective processes that only limit the effective use of such models.

▼ Purchasing Power Parity (PPP) is an important theory of
exchange rate determination. The documents probing into the PPP theory are voluminous nowadays; however, there hasnât been an agreed conclusion yet.
In this paper, we apply the Panel Lagrange Multiplier unit root
test, a newly developed panel unit root test that allows for heterogeneous
breaks, under both the null and the alternative, in both the
level and trend of the series under investigation, addressed by Im, Lee
and Tieslau (2010). The validity of PPP theory can be examined by testing the stationary of real
exchange rates. We use the
data chosen from the countries of Asia, including Taiwan, Japan, Korea, Tailand, Indonesia, Hong Kong and Singapore to proceed the positive analysis.
The result shows that no matter we use CPI or WPI as the price index, both considering more about the structure breaks and using the panel unit root test strongly support the PPP theory. And it also shows that when using the WPI as the price index, there would be much more countries support the PPP theory.
