▼ In the current business world, data collection for
business analysis is not difficult any more. The major concern
faced by business managers is whether they can use data to build
predictive models so as to provide accurate information for
decision-making. Knowledge Discovery from Databases (KDD) provides
us a guideline for collecting data through identifying knowledge
inside data. As one of the KDD steps, the data mining method
provides a systematic and intelligent approach to learning a large
amount of data and is critical to the success of KDD. In the past
several decades, many different data mining algorithms have been
developed and can be categorized as classification, association
rule, and clustering. These data mining algorithms have been
demonstrated to be very effective in solving different business
questions. Among these data mining types, classification is the
most popular group and is widely used in all kinds of business
areas. However, the exiting classification algorithm is designed to
maximize the prediction accuracy given by the assumption of equal
class distribution and equal error costs. This assumption seldom
holds in the real world. Thus, it is necessary to extend the
current classification so that it can deal with the data with the
imbalanced distribution and unequal costs. In this dissertation, I
propose an Iterative Cost-sensitive Naïve Bayes (ICSNB) method
aimed at reducing overall misclassification cost regardless of
class distribution. During each iteration, K nearest neighbors are
identified and form a new training set, which is used to learn
unsolved instances. Using the characteristics of the nearest
neighbor method, I also develop a new under-sampling method to
solve the imbalance problem in the second study. In the second
study, I design a general method to deal with the imbalance problem
and identify noisy instances from the data set to create a balanced
data set for learning. Both of these two methods are validated
using multiple real world data sets. The empirical results show the
superior performance of my methods compared to some existing and
popular methods.

▼ Although multiple
data link protocols that can handle 10's of Gbps have been developed over the years, engineers in the test industry either rely on dated standards such as RS-232 and GPIB or expensive dedicated hardware that is inflexible and costly. This work investigated building a framework for a test bench that is inexpensive, scalable, open source, and easily implemented. This work reviewed modern protocols such as USB, Ethernet, and PCI-Express to determine which protocol was the most practical as the backbone of the framework. The framework chose to rely on USB to provide the physical link and
data protocol to interface an FPGA to a PC. The interface within the PC is a virtual communications port that can be utilized by a simple terminal program or scripting language such as MATLAB. The sustained
data rates achieved by this framework were 480 Mbps or over 5,000 times faster than RS-232.

▼ Design, implementation and performance verification of an affordable field-based high-throughput plant phenotyping platform for monitoring Canola plants, including both
data acquisition/visualization software and measurement system, was the main objective of this research.
The primary motivation for this research is the fact that breeders need a well-organized approach and efficient tool to monitor and analyze a number of plant traits to achieve a higher yield. At the moment, manual measurement is a conventional approach to gather the required information for plant analysis. Nevertheless, manual measurement has many limitations especially to study a large-scale field. To address this bottleneck, a high-throughput plant phenotyping platform (HTPP) was developed which consists of a
data acquisition system, a
data storage unit, and a
data visualization and analysis software. Such an HTPP will be an essential asset for breeders to conveniently gather a comprehensive database which contains various information such as a plant height, temperature, Normalized Difference Vegetation Index (NDVI), etc.
To develop and implement such an HTPP, first, the overall system block diagram and required algorithms were drawn. Then to find the optimum set of equipment according to the requirement of this application, the performance of different sensors and devices were examined using literature search and experimental examinations in the laboratory setting. Then a mechanical boom was attached to the rear of a farm vehicle (a Swather) to carry different sensors, cameras and other measurement equipment (mechanical development of the boom structure was carried out by other members of the research team).
A control box containing power supplies, safety fuses, and a
data logger unit was attached to the farm vehicle, and a program was developed for
data logger to read sensors signals as well as GPS
data for
data geo-referencing and future retrieval purposes. The efficiency of different system architecture including different
data transmission networks was examined by conducting several field tests to minimize existing errors such as delays in synchronizing different steps. Three programs were developed in MATLAB GUI for image
acquisition via webcam and DSLR cameras as well as a central program for
data processing and interactive
data visualization.
The indoor tests were performed at the Robotics laboratory, University of Saskatchewan and outdoor experiments were performed on a Canola nursery at Cargill Canada, Aberdeen, SK, throughout spring-summer 2016 and 2017.
Finally, the performance and effectiveness of the developed field-based phenotyping platform was validated by various measures such as conducting some manual measurements and comparing the results with the values given by the platform. According to the achieved results, both hardware and software components of the proposed system meet the requirements of a field-based plant phenotyping platform as an essential asset for breeders for comprehensive study of Canola plants or any other…

▼ We are presenting a new way of improving seismic-array responses. By analyzing the relationship between the covariance matrix forms from the real sensors of seismic arrays and the fourth-order crosscumulants from the same sensors, we find that artificial sensors can be constructed from the real sensors. We have called these artificial sensors virtual sensors and the combination of real and virtual sensors a virtual seismic array. For example, we can construct from an equally weighted linear array of five sensors, a weighted virtual array of nine sensors. Basically, the virtual sensors allow us to introduce new sensors in the seismic arrays as well as new weightings of the existing real sensors.
The key assumption behind this approach is that seismic
data are considered nonGaussian; hence the fourth-order crosscumulants of the real sensor responses are nonzero.

▼ During the past years, radiotherapy has become a widely used technique for treatment of tumors on different areas of the human body. The evolution of the technology has led to the necessity to assure the safety of the patient at any time during any kind of treatment. A wide range of instrumentation has been developed to perform a state of art dosimetry for the Quality Assurance (QA) of the irradiating beam. Tumors can be treated using different methodologies, depending on their position and dimension. The radiation techniques have been classified in three major groups: Microbeam Radiation Therapy (MRT), Brachytherapy and External Beam Radiation Therapy (EBRT). Each of them presents different characteristics in terms of intensity of delivered dose, timing and speed of the irradiation. The aim of this research project is to study and design a unified Data Acquisition system (DAQ) able to monitor and measure the irradiating beam of any of the three clinical scenarios. A DAQ is a very complex system comprising multiple aspects. It can be divided in four main sections: detectors, the sensitive part; electronic and analogue front end; digital core and Graphical User Interface. The goal to create a unified dosimetry platform has been achieved by the design of a modular read out electronic section and a modular digital core, which can be easily adapted to the different detectors and analogue front ends. The project started with the development of a single channel DAQ to read out a single microstrip diode for MRT application. The goal of the DAQ was to have high spatial resolution, to resolve a 50 μm wide microbeam, and a large sensitivity range. In fact, for this application, the beam instead of being flat has very narrow peaks where high radiation dose is delivered, spaced by areas where radiation is very low or none (named valley). Then the system has been upgraded into a multi-channel DAQ able to acquire a 128 diodes array for Brachytherapy treatments. In this scenario, the source moves during the treatment and can be placed far away from the detector. By using an array of diodes, the system has been able to reconstruct the movement of the source at any time during the treatment. A new high sensitivity front end has been introduced to perform dosimetry up to 12 cm distance from the irradiating source. The same DAQ has been used in multi-channel configuration for EBRT treatments and its modular design allowed the introduction of larger detectors, up to 512 channels, to best suit each different application. Moreover, the flexible timing constraints of the front-end used to read out the detector, allowed the setup of a triggered acquisition which can be synchronized with the LINAC beam to have a highly efficient dosimetry measure. Lately, a new standalone section has been introduced: it comprises a rotatable phantom and its movement control. It features an inclinometer, which detects the position of the LINAC gantry, and a control system made by an encoder and a stepper motor to align the detector to the gantry. This…

▼ This thesis is comprised of three unique
data acquisition and controls (CDAQ) projects. Each of these projects differs from each other; however, they all include the concept of testing renewable or future fuel sources. The projects were the following: University of Kansas's Feedstock-to-Tailpipe Initiative's Synthesis Gas Reforming rig, Feedstock-to-Tailpipe Initiative's Biodiesel Single Cylinder Test Stand, and a unique Reformate Assisted Biodiesel Combustion architecture. The main responsibility of the author was to implement, develop and test CDAQ systems for the projects. For the Synthesis Gas Reforming rig, this thesis includes a report that summarizes the analysis and solution of building a controls and
data acquisition system for this setup. It describes the purpose of the sensors selected along with their placement throughout the system. Moreover, it includes an explanation of the planned
data collection system, along with two models describing the reforming process useful for system control. For the Biodiesel Single Cylinder Test Stand, the responsibility was to implement the CDAQ system for
data collection. This project comprised a variety of different sensors that are being used collect the combustion characteristics of different biodiesel formulations. This project is currently being used by other graduates in order to complete their projects for subsequent publication. For the Reformate Assisted Biodiesel Combustion architecture, the author developed a reformate injection system to test different hydrogen and carbon monoxide mixtures as combustion augmentation. Hydrogen combustion has certain limiting factors, such as pre-ignition in spark ignition engines and inability to work as a singular fuel in compression ignition engines. To offset these issues, a dual-fuel methodology is utilized by injecting a hydrogen/carbon monoxide mixture into the intake stream of a diesel engine operating on biodiesel. While carbon monoxide does degrade some of the desirable properties of hydrogen, it acts partially like a diluent in order to prevent pre-ignition from occurring. The result of this mixture addition allows the engine to maintain power while reducing biodiesel fuel consumption with a minimal NOx emissions increase.

▼ Over the last ten years there has been rapid growth in the digital forensics field. Forensically sound computer analysis and testimony is becoming a requirement during investigations related to frauds, missing persons, homicides etc. One of the phases of the digital forensic process is
data preservation, where a copy of
data from an original electronic storage device is collected in a verifiable manner, producing a forensic copy of the
data. A best practice for digital forensics is to capture a bit for bit or physical copy of the source device. However, the sizes of hard drive volumes have been increasing exponentially and in 2011, volume sizes for a single hard drive have reached the three terabyte threshold. The increase in volume size equates to an increase in processing time to collect the
data and an increase in media capacity to store the acquired
data.
The purpose of this research is to explore new tools and methods that will allow an examiner to collect
data from a source device in a time-efficient manner. Prior research has been conducted by the author, who concluded that
data collection processing times can be reduced by the use of compression algorithms during
data collection activities. However, the amount of time reduction depends on the type of
data that is resident on the storage device. A reduction in processing time is observed when collecting highly compressible
data. Conversely, an increase in processing time can occur when attempting to compress
data that does not compress well, during a collection process.
The focus of the research was to develop a means that would be able to determine and report the type of
data residing on a storage device. A fast and easy to use scanning tool is developed during the research. The scanning tool is capable of processing a storage device in four minutes and provides a report that accurately details the type of stored
data in terms of its compressibility. The information in the report regarding the data’s compressibility can assist the examiner when making decisions concerning the use of compression to reduce processing time during
data collection activities.

▼ The report is focused on the implementation of a data acquisition system that will be used for measuring different parameters which are needed in solar panel behavior analysis. To accomplish the DAQ system a DAQ board has been designed and implemented. This DAQ board acquires measured climatic parameters that affect the PV module behavior and voltage and current of a PV module. The DAQ board may take measurements of multiple analog and digital signals that come from various sensors including solar radiation, temperature, wind sensors and other measurement devices. The DAQ board may also output analog signals for controlling other devices. The DAQ board is the basic part of the DAQ system and several of them can be connected via a single communication bus (RS485). A unique slave ID can be assigned to each DAQ board on the communication bus, which allows the control of all boards via a GUI application installed on a master computer. Therefore, the DAQ system can be used for monitoring a PV module installation as well as logging the measured data in a data storage server. This report outlines the details of the DAQ system design which are helpful in utilizing or upgrading this system. These details also include programming of DAQ board and implementation of MODBUS communication protocol within the DAQ system.

▼ The bursty many-to-one communication pattern, typical for data acquisition
systems, is particularly demanding for commodity TCP/IP
and Ethernet technologies. The problem arising from this pattern is
widely known in the literature as incast and can be observed as TCP
throughput collapse. It is a result of overloading the switch buffers,
when a specific node in a network requests data from multiple sources.
This will become even more demanding for future upgrades of the experiments
at the Large Hadron Collider at CERN. It is questionable
whether commodity TCP/IP and Ethernet technologies in their current
form will be still able to effectively adapt to bursty traffic without
losing packets due to the scarcity of buffers in the networking hardware.
This thesis provides an analysis of TCP/IP performance in data acquisition
networks and presents a novel approach to incast congestion in
these networks based on software-based packet forwarding.
Our first contribution lies in confirming the strong analogies between
the TCP behaviour in data acquisition and datacenter networks. We
also provide experimental evaluation of different proposals from the
datacenter environment for application in data acquisition to improve
performance and reduce buffer requirements.
The second contribution lies in the design and experimental evaluation
of a data acquisition network that is based on software switches.
Performance has traditionally been the challenge of this approach, but
this situation changes with modern server platforms. High performance
load balancers, proxies, virtual switches and other network functions
can be now implemented in software and not limited to specialised
commercial hardware, thus reducing cost and increasing the flexibility.
We first design and optimise a software-based switch with a dedicated,
throughput-oriented buffering mechanism for data acquisition.
Our experimental results indicate that it performs significantly better
than some typical Ethernet switches under heavy congestion. The
optimised software switch with large packet buffer reaches maximum
bandwidth and completely avoids throughput degradation typical for
hardware switches that suffer from high packet drop counts.
Furthermore, we evaluate the scalability of the system when building
a larger topology of interconnected software switches. We highlight
aspects such as management, costs, port density, load balancing, and
failover. In this context, we discuss the usability of software-defined
networking technologies, Open vSwitch Database and OpenFlow, to
centrally manage and optimise a data acquisition network. We have
built an IP-only parallel leaf-spine network consisting of eight software
switches running on separate physical servers as a demonstrator.

▼ Simultaneous shooting achieves a much faster seismic
acquisition but poses a challenging problem for subsequent processing because of the interference from the neighbor crews. Separation of different sources, also called deblending, becomes important for the overall success of this
acquisition technology. I propose a novel iterative estimation scheme for separating the blended simultaneous source seismic
data to produce separate-source
data as if they were acquired independently. I construct an augmented estimation problem, then use shaping regularization to constrain the characteristics of the model during the inversion and to obtain a suitable estimation result. The
data reconstruction and source separation problems can be combined into one problem in order to make the future
acquisition more flexible and efficient. In order to best utilize the capability of median filtering in attenuating spike-like noise, I also propose to use a new type of median filter (MF), termed as space-varying median filter (SVMF) to remove blending noise. SVMF can be regionally adaptive, instead of rigidly using a constant window length through the whole profile for MF. Simultaneous-source seismic
data may also contain strong ambient random noise, so traditional denoising is still an important step. One of the most widely used approaches for removing random noise is using a sparse-transform thresholding strategy. I propose a double sparsity dictionary (DSD) for seismic
data in order to combine the benefits of both analytic transform and learning-based dictionary. In the DSD framework,
data-driven tight frame (DDTF) obtains an extra structure regularization when learning dictionaries, while the seislet transform obtains a compensation for the transformation error caused by slope dependency. DSD aims to provide a sparser representation than the individual transform and dictionary and therefore can help achieve better performance in denoising applications. Finally, considering that signal loss sometimes cannot be avoided in nearly all the existing denoising or deblending approaches. I propose a novel approach to retrieve the leakage energy from the initial noise section using local signal-and-noise orthogonalization. The proposed denoising approach corresponds to orthogonalizing the initially denoised signal and noise in a local manner. I evaluate denoising performance by using local similarity. The local signal-and-noise orthogonalization algorithm can also be used in the iterative deblending framework for obtaining better performance.

▼ Data acquisition from multiple analog channels is an important function in many embedded devices used in avionics, medical electronics, robotics and space applications. It is desirable to engineer these systems to reduce their size, power consumption, heat dissipation and cost. The goal of this research is to explore designs that exploit a priori knowledge of the input signals in order to achieve these objectives. Sparsity is a commonly observed property in signals that facilitates sub-Nyquist sampling and reconstruction through compressed sensing, thereby reducing the number of A to D conversions.
New architectures are proposed for the real-time, compressed
acquisition of streaming signals. A. It is demonstrated that by sampling a collection of signals in a multiplexed fashion, it is possible to efficiently utilize all the available sampling cycles of the analogue-to-digital converters (ADCs), facilitating the
acquisition of multiple signals using fewer ADCs. The proposed method is modified to accommodate more general signals, for which spectral leakage, due to the occurrence of non-integral number of cycles in the reconstruction window, violates the sparsity assumption. When the objective is to only detect the constituent frequencies in the signals, as against exact reconstruction, it can be achieved surprisingly well even in the presence of severe noise (SNR ~ 5 dB) and considerable undersampling. This has been applied to the detection of the carrier frequency in a noisy FM signal.
Information redundancy due to inter-signal correlation gives scope for compressed
acquisition of a set of signals that may not be individually sparse. A scheme has been proposed in which the correlation structure in a set of signals is progressively learnt within a small fraction of the duration of
acquisition, because of which only a few ADCs are adequate for capturing the signals. Signals from the different channels of EEG possess significant correlation. Employing signals taken from the Physionet database, the correlation structure of nearby EEG electrodes was captured. Subsequent to this training phase, the learnt KLT matrix has been used to reconstruct signals of all the electrodes with reasonably good accuracy from the recordings of a subset of electrodes. Average error is below 10% between the original and reconstructed signals with respect to the power in delta, theta and alpha bands: and below 15% in the beta band. It was also possible to reconstruct all the channels in the 10-10 system of electrode placement with an average error less than 8% using recordings on the sparser 10-20 system.
In another design, a set of signals are collectively sampled on a finer sampling grid using ADCs driven by phase-shifted clocks. Thus, each signal is sampled at an effective rate that is a multiple of the ADC sampling rate. So, it is possible to have a less steep transition between the pass band and the stop band, thereby reducing the order of the anti-aliasing filter from 30 to 8. This scheme has been applied to the
acquisition of voltages…

▼ Organisationer har idag tillgång till stora mängder data som inte kan hanteras av traditionella Business Intelligence‐verktyg. Big data karakteriseras av stor volym, snabb hastighet och stor variation av data. För att hantera dessa karaktärer av data behöver organisationer upphandla ett Big data‐system för att ha möjlighet att utvinna värde. Många organisationer är medvetna om att investeringar i Big data kan bli lönsamma men vägen dit är otydlig. Studiens syfte är att undersöka vilka utmaningar organisationer står inför i samband med upphandling av ett Big data‐system och var i upphandlingsprocessen dessa utmaningar uppstår. Det empiriska materialet har samlats in från tre stora svenska företag och myndigheter som har upphandlat ett Big data‐ system. Analys av materialet har genomförts med Critical Incident Technique att identifiera utmaningar organisationer upplever i samband med upphandling av ett Big data‐system. I studiens resultat framgår det att organisationer upplever utmaningar med att förstå behovet av ett Big data‐system, skapa projektgruppen, välja projektmetod, skapa kravspecifikationen och hantera känslig och personlig data.
Organizations today have access to massive amounts of data that cannot be handled by traditional Business Intelligence tools. Big data is characterized by big volume, high velocity and variation. Organizations need to acquire a Big Data system, in order to handle the characteristics of the data and be able to generate business value. Today’s organizations are aware that investing in Big Data can be profitable but getting there is a challenge. The purpose of this study is to investigate the challenges the organizations may experience in the process of acquiring a Big Data system and when these challenges arise. The empirical data has been collected by interviewing three large Swedish companies and authorities which have acquired a Big Data system. The Critical Incident Technique has been used in order to identify the challenges which the organizations had experienced in the process of acquiring a Big Data system. The findings of the study shows that organizations experience challenges when they are understanding the need of the Big data‐system, creating the project team, choosing the project method, defining the requirements of the system and managing sensitive and personal data.

▼ Flight
data recorders (FDRs) play a critical role in determining root causes of aviation mishaps. Some aircraft record limited amounts of information during flight (e.g. T-1A Jayhawk), while others have no FDR on board (B-52 Stratofortress). This study explores the use of image-based flight
data acquisition to overcome a lack of available digitally-recorded FDR
data. In this work, images of cockpit gauges were unwrapped vertically, and 2-D cross-correlation was performed on each image of the unwrapped gauge versus a template of the unwrapped gauge needle. Points of high correlation between the unwrapped gauge and needle template were used to locate the gauge needle, and interpolation and extrapolation were performed (based on locations of gauge tick marks) to quantify the value to which the gauge needle pointed. Results suggest that image-based flight
data acquisition could provide key support to mishap investigations when aircraft lack sufficient FDR
data.

▼ The content of this thesis is to understand a field of
data acquisition. There is explained what it is
data acquisition and also there are described frequently used terms and principles, which belong to this theme. We have to understand how to get useful information from a specific physical effect or event; how can be this information processed or represented. A part of this thesis describes hardware side of this mechanism – the most used buses and measuring systems, cards and modules belonging to it. There are also described used developing and measuring programmes, their features and system of output of applications besides. In the thesis we can see which tasks can use
data acquisition, which problems can appear and we have to know about them. As an example of the whole
data acquisition there are showed two tasks which are worked out in system of LabVIEW. Both tasks work with real mechanisms so they get real
data and we can work with them further.

▼ Rule induction is a popular technique for knowledge
acquisition and
data mining. Many techniques, such as ID3, C4.5, CART (tree induction tecniques) and Artificial Neural Networks have been developed and widely used. However, most techniques are either based on categorical or numerical mechanisms to assess the importance of different input variables, which may not produce the optimal rule when a mixture of variables exists.
In 1992, Liang proposed a composite approach called CRIS that use different method to analyze different types of
data in inducing rules for binary classification. Yang conducted a follow-up research to extend the original algorithm to multiple categories. However, both methods do not take variable interaction into consideration.
The purpose of this research is to extend previous approach and extend by including second-order interaction. We also take into consideration the kurtosis and skewness of
data for numerical variables. For categorical
data, we also adopt ID3 algorithm to handle classes with low representation in the sample. In order to evaluate this technique, we develop a prototype CRIS 3.0 and compare with existing techniques, including multi-category-CRIS, CART and C4.5 as benchmark. The results show that CRIS 3.0 has the highest probability of producing the highest prediction accuracy.

▼ The ARIANNA experiment is an ultra-high energy neutrino detector designed to detect cosmogenic neutrinos. The experiment uses the Ross Ice Shelf to detect RF signals which are generated when the high energy neutrinos interact with the ice. The experiment plans to use a massive deployment of hundreds of antenna array stations to capture neutrino events over a large area. The stations use a data acquisition system to capture and store the data and subsequently transmit the data back to UCI. This thesis describes the design, functioning and results of the newest generation system which was deployed in the field in the 2014 season. The new system utilizes a new data digitization chip developed by the ARIANNA engineering group led by Dr. Stuart Kleinfelder. The new SST chip is a largely simplified and streamlined design compared to the previous generation chip and utilizes advanced circuitry to achieve fully synchronous operation while reducing the power usage by many factors. The new system makes substantial improvements over the previous generation system and introduces a number of new features, while providing a possible design solution for the final design requirements of the ARIANNA array systems.

▼ Electrocardiography (EKG) is the process of detecting the heart beat data for a patient, who has to put electrodes on his/her body. These electrodes are able to detect the tiny electrical change on the skin between two different points that arise from the heart muscle depolarizing during each heart beat.Traditional EKG test can use up to 12 electrodes. The heart beat data is acquired by the electrodes over a certain period of time. The electrodes are capable of capturing the magnitude of the heart beat at any moment during a whole cardiac cycle. In this thesis, we build an EKG data acquisition system, Slug Heart. On our platform, the patients can have two channels (3 electrodes, one of them is the reference for both channels) or one channel (2 electrodes) on their body, then our EKG circuit board will capture and amplify their EKG signal. The bluetooth module on the board transfers the heart beat signal to Slug Heart Android App on their cell phone. By doing this, the patients will have a clear view of their EKG waveform. Our EKG data acquisition system is very small and convenient, and it is a platform for studying EKG data during other activities throughout the day. Our EKG data acquisition system is powered by a single coin cell battery, and it is able to support at least 2 days' continuous testing without interruption. In addition, our Slug Heart platform is low-cost.

▼ This thesis describes the development and implementation of a light-weight microcontroller on FPGA for high-speed
data acquisition. It details the design from the conceptualization stage through to its implementation on the FPGA board. Growing application demands and complexity have created a need for additional microcontroller choices. Our goal is to design a high performance microcontroller without the unnecessary features and components which usually adds to performance overhead when implemented for a specific application.
The initial stage of the development process involved the design of an 8-bit RISC microcontroller with a dual port RAM and its description in Very High Speed Integrated Circuit Hardware Description Language (VHDL).The later stages involved the implementation of the design on an FPGA board. The microcontroller was designed, verified, and implemented on a Xilinx Field Programmable Gate Array (FPGA) on a Windows platform. Our experimental results obtained using our light-weight microcontroller, demonstrated its use for high speed
data acquisition on an FPGA and how it compares to other existing commercial products on the market.

▼ Industrial facilities that plan the shutdown of equipment for service have large financial savings compared to those managing unplanned shutdowns. To this end, a variety
of algorithms have been developed and published in the literature that can monitor
a machine's health and indicate when the machine starts to develop a fault. In order
for such algorithms to be effective, they require raw
data collected from machines.
Often this involves the placement of accelerometers and other sensory devices for
measurements of mechanical behavior. It is possible to extract much of the required
information from the electrical signals of the equipment. This is normally a less expensive installation since one only needs access to the lines supplying electric power
to the equipment. If these
data acqusistion modules are accessible wirelessly, then
one can monitor all the interfaced equipment from a central location. To successfully
monitor such electrical equipment, a
data acquisition unit is required that can sample
on five or six channels simultaneously, depending on the switch gear configuration.
This thesis details the development of an "endpoint" device that samples the
required number of channels to monitor the electrical signals of industrial equipment,
and interfaces to a wireless network. The hardware and software design of the "endpoint" is discussed in detail. Also, the software design of the server that receives the
data from the "endpoint" is presented.
The designed "endpoint" samples up to six channels simultaneously, at a rate of
at least 8 kHz per channel, and a
data resolution of 16 bits. The
data are then transmitted wirelessly to a central server for processing. The system has been tested both
in a laboratory environment and at an industrial environment. The desired specifications of the "endpoint" have been verified in both environments. Several "endpoints"
have been assembled to form a network and have been tested in a laboratory setting.
This work has resulted in the demonstration that an "endpoint" can be constructed using of the shelf components that is suitable for the continuous health
monitoring of multi-phase electric machines through a wireless network.

▼ Experiments were performed to investigate the effects of shock waves – generated by explosive processes – on enhancing enzymatic digestibility of corn stover for conversion into biofuels, chemicals, or animal feed. Following an alkaline chemical pretreatment process, shock treatment was performed, which increased digestibility. Digestibility was assessed at a standard enzyme loading of 46.7 mg protein/g glucan. Without shock, the enzymatic conversion was 0.80 g glucan digested/g glucan fed. With shock, the enzyme loading is reduced by ~2× while maintaining a constant conversion.
Shotgun shells and hydrogen detonation produced identical digestibility increases; however, hydrogen detonation eliminated the need to magnetically remove contaminants introduced from shotgun shells. Contrary to initial hypotheses, varying vessel geometry (depth = 1–3 ft, diameter = 4–8 in) or process conditions (peak pressure = 2.07–12.1 MPa, and solids concentration = 5–10%) had an insignificant impact on shock treatment efficacy within the experimental domain tested. Instead, the pressurization rate is the key parameter when scaling the shock treatment process. Specifically, the shotgun shell blast (108,000 MPa/s) and hydrogen detonation
(4,160,000 MPa/s) generate pressure quickly enough to enhance digestibility; in contrast, the propane deflagration (37.2 MPa/s) did not.
Therefore, process scaling is extremely simple, because a vessel that contains gas detonations should suffice. A slurry pump enables rapid cycling of the 20-L shock tube to already function at a commercially relevant scale. The maximum benefit of shock treatment has yet to be determined. Subsequent experiments performed with plasma discharge and solid explosives failed to increase digestibility, at the conditions employed; but, liquid-phase shock waves may be more effective.

▼ Since its inception in the nineteenth century, the Internal Combustion Engine (ICE) remains the most prevalent technology in transportation systems to date. In order to minimize emissions, it is important that ICE is operated according to its optimized design conditions. As such, condition monitoring and Fault Detection and Diagnosis (FDD) tools can play an important role in detecting conditions that would affect the operability of the engine. In this research, different signal-based Fault Detection and Diagnosis (FDD) techniques are researched and implemented for fault condition monitoring of ICE. The implementation of prognostics for the engine in an automated form has important consequences that include cost savings, increased reliability, reduction of GHG emissions, better safety, and extended life for the vehicle.
In this research, in order to carry out FDD onboard, a low-cost and flexible internet-based data-acquisition system (DAQ) was designed and implemented. The main part of the system is an embedded hardware running a full desktop version of Linux. This sensory system leverages the positive aspects of both real-time and general-purpose architectures to ensure engine monitoring at high sampling rates. Unlike other commercial DAQ systems, the software of this device is open-source, free of charge, and highly expandable to suit other FDD applications.
In addition to data collection at high sampling rates, the FDD system includes advanced FDD strategies. The Fault Detection and Diagnosis strategies considered use a combination of Fourier Transforms (FT), Wavelet Transforms (WT), and Principal Component Analysis (PCA). Meanwhile, Fault Classification was carried using Neural Networks consisting of the Multi-Layer Perceptron (MLP). Three strategies were comparatively considered for the training of the Neural Network (NN), namely the Levenberg-Marquardt (LM), the Extended Kalman Filter (EKF), and the Smooth Variable Structure Filter (SVSF) techniques. The proposed FDD system was able to achieve 100% accuracy in classifying a set of engine faults.

▼ Current epidemiological
data showing that the use of the injectable contraceptive progestin Depotmedroxyprogesterone acetate (DMPA) is associated with increased HIV-1
acquisition is controversial. However, animal and ex vivo
data reveal plausible biological mechanisms whereby MPA may increase HIV-1
acquisition. Relatively high levels of endogenous progesterone (P4) found in the luteal phase of the menstrual cycle have also been linked to increased HIV-1
acquisition in animal, clinical and ex vivo models. One of the central hypotheses of the present study was that the mechanism of MPA-induced increase in HIV-1 infection occurs via a different mechanism to that of the luteal phase. Furthermore, MPA has been shown to activate both the glucocorticoid receptor (GR) and its target, the progesterone receptor (PR) isoform B (PR-B), which are both transcription factors and regulate genes involved in immune function. Both the GR and PR are expressed in the cervix, the primary site of heterosexual HIV-1 infection. PR is regulated by endogenous estrogen (E2), of which the concentrations fluctuate throughout the menstrual cycle, and GR expression also varies in response to stress hormones, leading to conditions of varied relative levels of GR/PR. The immune-related consequences of changing the relative levels of GR and PR-B are not well understood. Therefore another hypothesis of this study was that changing the relative levels of GR/PR-B modulates HIV-1 infection and immunomodulatory gene expression in response to the GR/PR agonist, MPA. Since GR and PR-B recognize similar DNA target sequences and may regulate the same genes at the same time, the final hypothesis of the present study was that GR and PR-B reciprocally modulate each other’s activity, through possible association. To investigate the effects of exogenous hormones on HIV-1 infection and mechanisms thereof, peripheral blood mononuclear cells (PBMCs) and TZM-bl cervical cells were used as model systems for HIV-1 infection. These cells were stimulated with P4 and E2 at concentrations mimicking the menstrual cycle phases or with levels of MPA at the upper range of peak serum levels detected in DMPA users. Cells were infected with the R-tropic HIV-1 infectious molecular clone, HIV-1Bal_Renilla and luciferase assays were used to measure HIV-1 infection. Levels of HIV-1 CD4 receptor and CCR5 co-receptor protein or mRNA were measured by flow cytometry or qPCR, respectively, while activation of CD4+ T cells using the activation marker CD69 was measured by flow cytometry in PBMCs. To investigate the effects of changing GR/PR-B levels on HIV-1 infection and immune gene regulation, GR/PR levels were altered in End1/E6E7 immortalized endocervical and HeLa/TZM-bl cervical carcinoma cells by GR siRNA knockdown with or without the simultaneous over-expression of PR-B, and cells were stimulated with MPA or the GR agonist Dexamethasone. mRNA expression iii of key immunomodulatory genes in End1/E6E7 and HeLa cells was measured by qPCR. The modulation of GR activity by PR-B was assessed…

▼ The main approach to studying the proteome is a technique called
data dependent
acquisition (DDA). In DDA, peptides are analyzed by mass spectrometry to determine the protein composition of a biological isolate. However, DDA is limited in its ability to analyze the proteome, in that it only selects the most abundant ions for analysis, and different protein identifications can result even if the same sample is analyzed multiple times in succession.
Data independent
acquisition (DIA) is a newly developed method that should be able to solve these limitations and improve our ability to analyze the proteome. We used an implementation of DIA (SWATH) to perform relative protein quantitation in the model bacterial system, Clostridium stercorarium, using two different carbohydrate sources, and found that it was able to provide precise quantitation of proteins and was overall more consistent in its ability to identify components of the proteome than DDA.
Relative quantitation of proteins is an important method that can determine which proteins are important to a biochemical process of interest. How we determine which proteins are differentially regulated between different conditions is an important question in proteomic analysis. We developed a new approach to analyzing differential protein expression using variation between biological replicates to determine which proteins are being differentially regulated between two conditions. This analysis showed that a large proportion of proteins identified by quantitative proteomic analysis can be differentially regulated and that these proteins are in fact related to biological processes.
Analyzing changes in protein expression is a useful tool that can pinpoint many key processes in biological systems. However, these techniques fail to take into account that enzyme activity is regulated by other factors than controlling their level of expression. Activity based protein profiling (ABPP) is a method that can determine the activity state of an enzyme in whole cell proteomes. We found that enzyme activity can change in response to a number of different conditions and that these changes do not always correspond with compositional changes. Mass spectrometry techniques were also used to identify serine hydrolases and characterize their expression in this organism.

▼ Embedded systems are utilized in various modern-day applications in order to ease routine tasks that are otherwise demanding in manpower; an example of which is data sensing and acquisition. Modern sensor applications usually involve one or more embedded microcomputer systems with inputs from various sensors and a means of connection to transmit the acquitted data to its point of interest. While many sensor and acquisition applications and standards exist for industrial use, the consumer/small business markets for such devices seem to be fairly bleak in comparison. In this project, various data communication standards for transmitting information between sensors and acquisition devices are investigated. Wired, such as RS232, I²C, SPI and 1-Wire, as well as wireless protocols like Wi-Fi and ZigBee were studied. Then, a generic wireless data acquisition platform is designed and realized. The reference implementation connects to a wireless LAN network over Wi-Fi, starts a web server and serves HTML5 web pages and a CSS3 style sheet from SPI flash memory. The sensor data is collected from integrated sensor circuits over an I²C link. Device can run on 3 AA batteries for a combined uptime of at least 3 weeks. Lastly, possible expansion options for the implemented device are discussed and supplemented with real-world examples where possible. Feasible consumer applications for such a platform are then given to conclude.

▼ Data independent
acquisition (DIA) mass spectrometry is a powerful technique that is improving the reproducibility and throughput of mass spectrometry-based proteomics studies. Here we explore several new approaches to leverage this technology. First we present an overview of modern
data independent
acquisition techniques, and demonstrate their internal detection rate and quantification consistency relative to targeted parallel reaction monitoring (PRM) and
data dependent
acquisition (DDA) methods despite large variations in
data sampling strategies. Second, we use DIA experiments to construct a prediction model that helps determine optimal peptide selection for targeted experiments. Third, we introduce a new experimental workflow that uses chromatogram libraries to enable sensitive peptide detection in quantitative experiments, while still maintaining the throughput necessary for large scale experiments. Finally, we discuss a new approach to statistically validate phosphopeptide positional isomers and explore their prevalence in studies of Human cells.
