▼ A
synchronization solution is developed in order to allow finer grained segmentation of clock domains on a chip. This solution incorporates computation into the
synchronization overhead time and is called Gradual
Synchronization. With Gradual
Synchronization as a
synchronization method the design space of a chip could easily mix both asynchronous and synchronous blocks of logic, paving the way for wider use of asynchronous logic design.

▼ The problem of
synchronization arises in the interaction among
digital systems not sharing a common clock reference. The reliability of synchronizers is related to metastable operation of
bistable elements. Because of its subtle nature, the phenomenon
until recently was not widely researched. However, the literature
now contains a sound theoretical basis concerning the nature of
metastability and its relationship to
synchronization failure.
Methods exist for construction of circuits with high
synchronization
reliability.
This paper describes the performance of synchronizers constructed in an integrated CMOS technology. A discussion of the
characteristics of CMOS circuits in metastable operation is given,
with attention to various device capacitances. The effect of transient channel charging current is included. A high-performance CMOS
realization is described and experimental measurements of the
synchronization reliability are compared with predicted performance
curves. A comparison to NMOS circuits is given.

▼ Indiana University-Purdue University Indianapolis (IUPUI)
Neural synchrony in the brain at rest is usually variable and intermittent, thus intervals of predominantly synchronized activity are interrupted by intervals of desynchronized activity. Prior studies suggested that this temporal structure of the weakly synchronous activity might be functionally significant: many short desynchronizations may be functionally different from few long desynchronizations, even if the average synchrony level is the same. In this thesis, we use computational neuroscience methods to investigate the effects of (i) spike-timing dependent plasticity (STDP) and (ii) noise on the temporal patterns of synchronization in a simple model. The model is composed of two conductance-based neurons connected via excitatory unidirectional synapses. In (i) these excitatory synapses are made plastic, in (ii) two different types of noise implementation to model the stochasticity of membrane ion channels is considered. The plasticity results are taken from our recently published article, while the noise results are currently being compiled into a manuscript.
The dynamics of this network is subjected to the time-series analysis methods used in prior experimental studies. We provide numerical evidence that both STDP and channel noise can alter the synchronized dynamics in the network in several ways. This depends on the time scale that plasticity acts on and the intensity of the noise. However, in general, the action of STDP and noise in the simple network considered here is to promote dynamics with short desynchronizations (i.e. dynamics reminiscent of that observed in experimental studies) over dynamics with longer desynchronizations.

▼ This thesis deals with two problems in viscous flow.In
the first part, fluid-structure interactions were investigated,
with connections to swimming microorganisms. Motivated by a
numerically proposed swimming mechanism, we studied an elastic
straight rod rotating on an imaginary cone. The shapes of the rod
which rotates at either prescribed torques or speeds were
experimentally measured and theoretically calculated. The rod
undergoes a discontinuous transition to a helical shape at a
critical torque, with increased propulsion force. A simple model
was presented to capture and explain the essential physics. In
addition, the longstanding hypothesis of hydrodynamic
synchronization was investigated using a scale model experiment. We
demonstrated that hydrodynamic interactions can cause
synchronization between rotating paddles driven at constant torque
if the shafts supporting the paddles have some flexibility. The
synchronization state depends on the symmetry of the paddles and
the torque mismatch. Excellent agreements were shown between the
experiments and the regularized stokeslets simulations. And a
simple analytic theory was built to predict the
synchronization
time as a function of paddle separation.In the second part, contact
drop formation on a hydrophobic surface was examined experimentally
and theoretically. A wide range of droplet sizes can result from
the same syringe by varying the dispensing speed. Three dispensing
regimes were identified according to the motion of the contact
line, a line coexisting between liquid/vapor/solid interfaces. In
the fixed and the expanding contact-line regimes, a power
dependence of the drop sizes on the dispensing speeds was observed
experimentally and obtained theoretically. In the receding
contact-line regime, the contact-line motion consists of two
stages: a slow retraction at the beginning and a rapid retraction
immediately prior to drop breakup. The dispensing process was
modeled as a stretching liquid bridge with a free moving
contact-line. A quasi-static analysis and numerical calculations
were performed to accurately predict the initial evolution of the
liquid bridge and the final breakup respectively. The influences of
the contact-line movement on the onset instabilities of liquid
bridges and thus the deposited drop sizes were
discussed.

▼ With the development of projector technology, portable projectors called pico-projectors are emerging on the market. To achieve a high quality projection, multiple pico-projectors can be used to display the same video, where accurate synchronization is required. The target of this thesis is to design and implement a Linux-based application which can synchronize multimedia playback over a WPAN with high accuracy. By analyzing the synchronization requirements, the synchronization problem is decomposed into playback synchronization and clock synchronization. To achieve a synchronized playback based on synchronized clocks, we explore several open source projects and eventually build a synchronized player which can play video with frame-by-frame level synchronization. For clock synchronization, the principles of a typical computer clock and the most popular time synchronization – NTP are studied. Based on that, a new time synchronization protocol with quick-start and anti-interference properties is designed. We also conduct a survey to test if the application meets the users’ requirement of synchronized playback. The final results show that our application provides a synchronized playback with the accuracy which is acceptable for most users.

▼ The purpose of this dissertation is to study synchronous behavior of certain nonlinear dynamical systems by the method of contraction theory. Contraction theory provides an elegant way to analyze the behavior of certain non- linear systems. Under sometimes easy to check hypotheses, systems can be shown to have the incremental stability property that trajectories converge to each other. This work provides a self contained introduction to some of the basic concepts and results in contraction theory. As we will discuss later, contractivity is not a topological, but is instead a metric property: it depends on the norm being used in contraction theory and in fact an appropriate choice of norms is critical. One of the main contributions of this dissertation is to generalize some of the existing results in the literature which are based on L2 norms to results based on non L2 norms using some modern techniques from nonlinear functional analysis. The focus of the first main part of this dissertation is on the application of con- traction theory and graph theory to synchronization in complex interacting systems that can be modeled as an interconnected network of identical systems. We base our approach on contraction theory, using norms that are not induced by inner products. Such norms are the most appropriate in many applications, but proofs cannot rely upon Lyapunov-like linear matrix inequalities, and different techniques, such as the use of the Perron-Frobenious Theorem in the cases of L1 or L∞ norms, must be introduced. On the second main part of this work, using the method of contraction theory based on non L2 norms, spatial uniformity for the asymptotic behavior of the solutions of a reaction diffusion PDE with Neumann boundary conditions will be studied.

▼ Nowadays an increasing number of applications need to maintain local copies of remote data sources to provide services to their users. Because of the dynamic nature of the sources, an application has to synchronize its copies with remote sources constantly to provide reliable services. Instead of push-based
synchronization, we focus on pull-based strategy because it doesn’t require source cooperation and has been widely adopted by existing systems.
The scalability of the pull-based
synchronization comes at the expense of increased inconsistency of the copied content. We model this system under non-Poisson update/refresh processes and obtain sample-path averages of various metrics of staleness cost, generalizing previous results and studying its statistical properties.
Computing staleness requires knowledge of the inter-update distribution at the source, which can only be estimated through blind sampling – periodic downloads and comparison against previous copies. We show that all previous approaches are biased unless the observation rate tends to infinity or the update process is Poisson. To overcome these issues, we propose four new algorithms that achieve various levels of consistency, which depend on the amount of temporal information revealed by the source and capabilities of the download process.
Then we focus on applying freshness to P2P replication systems. We extend our results to several more difficult algorithms – cascaded replication, cooperative caching, and redundant querying from the clients. Surprisingly, we discover that optimal cooperation involves just a single peer and that redundant querying can hurt the ability of the system to handle load (i.e., may lead to lower scalability).

▼ The advent of chip multi-processors has led to an increase in computational performance in recent years. Employing efficient parallel algorithms has become important to harness the full potential of multiple cores. One of the major productivity limitation in parallel programming arises due to use of
Synchronization Primitives. The primitives are used to enforce mutual exclusion on critical section data. Most shared-memory multi-processor architectures provide hardware support for mutually exclusive access on shared data structures using lock and unlock operations. These operations are implemented in hardware as a set of instructions that atomically read and then write to a single memory location. Good
synchronization techniques should try to reduce network bandwidth, have low access time in acquiring locks and be fair in granting requests.
In a typical directory controller based locking scheme, each thread communicates with the directory controller for lock request and lock release. The overhead of this design includes communication with the directory controller for each step of lock acquisition, and this causes high latency transactions. Thus, a significant amount of time is spent in communication as compared to the actual operation.
Previous works have focused on reducing the communication to home node through various techniques. One such technique of interest is the Implicit Queue on Lock Bit Technique (IQOLB). In this technique, the lock is forwarded directly to the requestor from the thread currently holding the lock without communication through the home node. Limitations of the method include the following: the forwarding operation can take place only after the current thread holding the lock has received information about the new lock requestor from the home node and also modification to cache coherence protocol to distinguish a regular memory read request and a
synchronization
request.
Very little research has been performed in the area of lock prediction. We believe based on data analysis that lock communication is predictable and the prediction can improve performance significantly. This research focuses on predicting the sequence in which locks are acquired so that the thread currently holding the lock can preemptively invalidate the locked cache line and forward the same to subsequent requestors and hence reduce the time taken to acquire a lock. The predictor is adaptive: whenever a lock is biased towards a thread, it will remain in the cache of that particular thread, and invalidation will not take place. The benefits of the technique include reduction in the number of messages exchanged with the home node without any modification to the cache coherence protocol (does not distinguish a regular memory read request and
synchronization request). The results of the evaluation of lock predictor on PARSEC benchmark suite shows an improvement in overall performance by an average of 9 % over the base case.

▼ Ph.D. (Electrical & Electronic Engineering)
In the ideal communication system no noise is present and error free communication is possible. In practice, however, several factors influence the correctness of· the communication. One of the most important of these factors is the synchronization of the message. Synchronization techniques form an integral part of data communication systems and without synchronization no comprehensible message can be received. An example of a communication system in which synchronization errors occur is the plesiochronous communication network which is used in many telephone networks [49,50]. A common problem with the use of the multiplexers in such a network is that output pulses may occur that do not contain valid data, due to minor discrepancies in the clock frequencies of the incoming signals. These inserted bits are termed ''justification bits" and their presence is signaled over the link by the justification control bits or stuffing control bits, which are included in the frame [49 and 50]. Synchronization of the network is dependent, among other factors, on the correct decoding of the stuffing control bits. Synchronization at the receiver can also be lost when the frame markers are not recognizable due to errors on the channel...

▼ Localization is very important for self-organizing wireless networks. The localization
process involves two main steps: ranging, i.e., estimating the distance
between an unlocalized node and the anchor nodes within its range, and the localization
algorithm to compute the location of the unlocalized nodes using the
anchor coordinates and the estimated ranges. To be able to estimate the distance,
the receiver needs to detect the arrival time of the received signals precisely. Thus,
the first part of this research is related to time
synchronization.
We propose two new symbol timing offset estimation (STO) algorithms that can
detect the start of an orthogonal frequency division multiplexing (OFDM) symbol
more accurately than others in a Rayleigh fading channel. OFDM is used to perform
timing
synchronization because it is incorporated inmany current and future
wireless systems such as 802.11, WiMAX, wireless USB, and WiMedia. The first
proposed algorithm uses a metric that is calculated recursively. Two estimation
methods are considered: one using the average of the metric results, and the other
using the median. The second approach uses a preamble designed to have a maximum
timing metric for the correct location and very small values otherwise. These
algorithms are shown to outperform recent algorithms in the literature.
In the second part of this dissertation we explore the second step of the localization
problem. There are two kinds of localization: range-free and range-based.
A new distributed range-free localization algorithm is proposed where every unlocalized
node forms two sets of anchors. The first set contains one-hop anchors
from the unlocalized node. The second set contains two-hop and three-hop anchors
away from the unlocalized node. Each unlocalized node uses the intersections
between the ranging radii of these anchors to estimate its position.
Four different range-based localization algorithms are proposed. These algorithms
use techniques from data mining to process the intersection points between
an unlocalized node and nearby anchors. The first proposed scheme is based on
decision tree classification to select a group of intersection points. The second is
based on the decision tree classification and K-means clustering algorithms applied
to the selected intersection points by the decision trees. The third is based on
decision tree classification and the density-based spatial clustering of applications
with noise (DBSCAN) algorithm applied to the intersection points selected by decision
trees. The last approach uses the density-based outlier detection (DBOD)
algorithm. DBOD assigns density values to each point being used in the location
estimation. The mean of these densities is calculated and those points having a
density larger than the mean are kept as candidate points. These proposed approaches
are shown to outperform recent algorithms in the literature.

▼ Every day, millions of people ask what time it is. Depending on the person and their reason for asking, the required accuracy and precision of an answer varies. Humans are not the only ones that care about time though, (perhaps more importantly) countless electronic devices ranging from cell phones to satellites do as well. Without accurate and precise frequency references and timekeeping systems, many of the electronics in use today would function incorrectly.The primary goal of this thesis was to achieve both
synchronization and syntonization using a Global Positioning System (GPS) receiver called Namuru, which was developed at the University of New South Wales (UNSW). In the former case, this means that the pulse per second (PPS) signals output by the receiver should be aligned with the second boundaries of GPS Time (GPST). In the latter case, this means that the frequency of the voltage-controlled temperature-compensated crystal oscillator (VC-TCXO) onboard the receiver should be equal to its setpoint. The secondary goal of this thesis was to develop a clock model that accurately simulated the
synchronization and syntonization performance of the receiver. The tertiary goal of this thesis was to develop supplementary features for the receiver like position-hold and holdover modes.In order to achieve these goals, several new capabilities were added to the receiver and much work was done in a number of different areas, such as field-programmable gate array (FPGA) programming, writing firmware, modifying hardware, and modeling.

▼ This paper investigates the complex systems and the dynamical behaviors in disordered-coupled random Boolean networks. In first part, we give a simple introduction to Kauffmanâs network and cellular automata, and apply them to study the virus dynamics and spatial distribution of ant lions. In the second part, a disordered coupling mechanism is introduced to study the dynamical behaviors (especially the
synchronization phenomena) of random Boolean networks. Though the interactions between networks are microscopic, we formulate a macroscopic coupled model to describe the dynamics of the original system. The model tallies well with the original system. When the coupling strength exceeds the critical value, the coupling is sufficient to overcome the divergent nature of non-linearity and mutual
synchronization is achieved. The finite size effect and different coupling configuration are also under our discussion.

▼ Orthogonal frequency-division multiplexing (OFDM) has
been employed in several current and future 4-th generation (4G)
wireless standards. Frequency offsets in OFDM introduce
intercarrier interference (ICI). Channel estimations are also
required. This thesis focuses on the channel and frequency offset
estimation for OFDM-based systems. For cooperative-relay OFDM with
frequency offsets, where inter-relay interference (IRI) exists,
channel estimation is developed. Optimal pilot designs are proposed
by minimizing the IRI in the mean square error (MSE) of the least
square (LS) channel estimation. The impact of frequency offset on
the channel estimation accuracy is derived. The pairwise error
probability (PEP) with both the frequency offset and channel
estimation errors is evaluated. The power allocation is discussed.
For multiple-input multiple-output (MIMO) OFDM systems, channel and
frequency offset estimation errors are investigated. The
signal-to-interference-and-noise ratio (SINR) is first analyzed
given channel and frequency offset estimation errors. The bit error
rate (BER) is then approximated for multiple-antenna reception with
maximal ratio combing (MRC) and equal gain combining (EGC). For
orthogonal frequency-division multiplexing access (OFDMA) systems,
the variance of the frequency offset estimation is derived as a
function of SINR and signal-to- noise ratio (SNR). This variance
information is exploited to improve the accuracy of frequency
offset estimators. A successive interference cancellation
(SIC)-based frequency offset estimator is also developed. The
accuracy of frequency offset estimation of the OFDMA uplink can
also be improved by using the cooperative relaying. Both
conventional amplify-and-forward (AF) relays and new
decode-and-compensate-and-forward (DcF) relays are studied. The
frequency offset estimate is derived from combining different link
estimates. In addition, when CSI is available, a scheme is proposed
to adaptively switch between the cooperative and conventional (no
relaying) transmissions to optimize the frequency offset
estimation.

SEPARATION OF CONCERNS IN CONCURRENT PROGRAMS USING FINE

▼ With the advent of multicore processors, there is
an increasing amount of interest in building concurrent
applications capable of fully utilising their features. Developing
applications for these platforms to take full advantage of the
power of multicore capabilities remains a complex, error-prone, and
challenging endeavour. Unfortunately, concurrency is not uniformly
and externally expressed in most existing application models. The
result is that concurrency and thread management are hidden within
objects or components and intermixed with their functionalities.
After demonstrating the tangling of code that results from the
interaction of these two major concerns, this thesis describes a
method of improving the concurrent program by applying a novel
technique to separate the concerns: aspect-oriented programming,
which aims to encapsulate concerns that crosscut the main program
flow in separate entities into aspects.The most mature
aspect-oriented tool available at the time this project was being
undertaken is AspectJ, which is an extension of Java. AspectJ can
be used to write an aspect to a separate concern in a sequential
program to avoid code tangling, but it is often inapplicable for
concurrent programs. The problem lies in the fact that the points
where parallelisation should occur are not natural join points in
AspectJ (i.e. points where AspectJ can intervene). Consequently,
this thesis proposes a set of fine-grained join points capable of
completely handling concurrent programs. This model goes beyond
present AspectJ models and demonstrates the need to recognise
complex behaviour for an effective separation of concerns.Finally,
aspects for implementing concurrent programs according to different
schemes are presented, together with evaluation results. This
highlights the flexibility of aspects for implementing concurrent
programs, a flexibility which is always a cross-cutting concern
with respect to the main concern of base
applications.

▼ In the 70s, the interplay between microscale electronics and mechanics gave birth to micro- and nanoelectromechanical systems (MEMS/NEMS) that are prevalent in our daily life. The emergence of silicon photonics in the 90s was a result of the marriage between microelectronics and optics promising extreme communication bandwidth and processing power. A few years ago, the field of microscale optomechanics that harnesses the interaction between light and mechanics on a nanoscale emerged. The field witnessed the birth of many exciting technologies as quantum limited detection of ultra-weak forces, preparation of micromechanical oscillators close to their motional quantum ground states and enabling self-sustaining oscillations of mechanics with light. The aim of this thesis is to explore and address a few challenges in coupled optomechanical systems. So far, most work in this area focuses on single device behaviors. One could imagine that like connecting many transistors together leads to complex computing machines, a network of coupled optomechanical devices have the potential to offer dynamics that are not accessible with single optomechanical devices. In this thesis, I show that indeed, light can be used to synchronize arrays of mechanical oscillators even when they are not physically connected. I will also show in this thesis that coupling distinct optical and mechanical elements together could also enable a new paradigm of devices. We couple a single Carbon Nanotube (CNT) strongly to on-chip high-Q optical microcavi- ties. Despite the tiny size of CNT, we show that the optical microcavity is still extremely sensitive to the CNT motion. We demonstrate that we can observe in real-time the thermal Brownian motion of a single CNT for the first time. The unique carbon-optical system also enables an almost completely dissipative optomechanical system that has not been achieved in any other type of systems to date.

▼ Today, it is a major issue for mobile applications to maintain a replica state of the server on mobile devices. This creates the need to keep data on both the server and the mobile. In such cases, when the data changes on the server, the new state of the data has to be updated on the mobile in order to maintain a consistent view of the data flow. However, mobile devices communicate over wireless mediums (.e.g., Bluetooth, Wi-Fi, 3.5G/4G, etc.) which can experience intermittent connectivity. The volatility of the network is also influenced by low-bandwidth. The direct effects of these issues are high latency and inconsistency issues between the data on the mobile clients and the remote servers. In this work, I present a detail review on the topic of data
synchronization in mobile networks. Then, a generic architecture called MobiQ is proposed which can keep working in an offline mode to record local modifications and can synchronize with the remote servers when connectivity is restored. This is achieved through the proposal of an efficient
synchronization protocol which combines different
synchronization and replication strategies. Moreover, the MobiQ framework provides a secured environment to work with data. The implemented architecture is designed and tested in mobile questionnaire system and the result is encouraging.

▼ Data
synchronization is the problem of bringing multiple versions of the same data on different remote devices to the most up to date version. This thesis looks into the particular problem of key-value storage systems
synchronization between mobile devices in a peer-to-peer environment. In this research, we describe, implement and evaluate a new key-value storage system
synchronization algorithm using a 2-phase approach, combining approximate
synchronization in the first phase and exact
synchronization in the second phase. The 2-phase architecture helps the algorithm achieve considerable boost in performance in all three major criteria of a data
synchronization algorithm, namely
synchronization time, processing time and communication cost, while still being suitable to operate in a peer-to-peer environment. The performance increase makes it feasible to employ database
synchronization technique in a wider range of mobile applications, especially those operating on a slow peer-to-peer network.

▼ The goal of this dissertation is to design a reliable and efficient communication system for downhole acoustic communication. This system is expected to operate in two different modes. A broadband high data rate mode in case of transmission of an image or a video file and a narrowband low data rate mode in case of transmission of sensor readings. This communication system functions by acoustic vibration of the pipes and uses them as the channel instead of installing long cables in areas that are hard to reach. However, this channel has unique characteristics where it exhibits several passbands and stopbands across the frequency spectrum. The communication system is expected to get around those challenges in both modes of operation. In the broadband case, the system uses Orthogonal Frequency Division Multiplexing to transmit data across multiple orthogonal frequencies spanning multiple passbands combined with an error-correction code to recover some of the losses caused by the channel. In the narrowband case, a short packet is transmitted at a low data rate where the signal spectrum can fit inside one passband. However, transmitting short packets induces a new
synchronization problem. This dissertation investigates and explores in detail the problem of
synchronization on short packets where each
synchronization stage is examined. A simple algorithm that exploits the presence of error-correction codes is proposed for the frame
synchronization stage and demonstrated to approach the optimal solution. Then, all
synchronization stages are combined in order to study the effect of propagated errors caused by imperfect
synchronization from one stage to the next and what can be done in the design of the packet and the receiver structure to mitigate those losses. The resulting
synchronization procedure is applied to the pipe strings and demonstrated to achieve desirable levels of performance with the assistance of equalization at the receiver.

▼ This dissertation investigates the different organizational structures of paratransit services that cover large regions. A paratransit service is demand-responsive, shared-ride transit service using vans or small buses. It is characterized by the use of vehicles that do not operate on a fixed route or a fixed schedule. The paratransit route and schedule are arranged from a user-specified origin to a user-specified destination, and at a user-specified time.
To retain productivity by focusing on shorter trips within a denser area, some larger systems have outsourced operations to more than one contractor, with each contractor responsible for the service zone to which their vehicles have been assigned. This service design is called a "zonal structure" or a "zoning approach."
The zoning with transfer system coordinates vehicles' schedules at various transfer locations. The schedule coordination of inter-zonal mechanisms of transportation likely reduces trip costs by increasing the ridesharing rate and lowering the number of empty return miles.
This study first presents the exact formulation for a coordinated decentralized paratransit system in order to compare its productivity and service quality with independent decentralized and centralized strategies. The formulation is then proven to work correctly, and the results of the computational experiments of small scale instances are shown to demonstrate that the proposed coordinated system is superior to independent decentralized systems in terms of passenger miles per vehicle revenue mile.
In the second section, this study develops an insertion-based heuristic method in order to compare the performances of different operational designs when applied to a large-scale system. In an experiment utilizing Houston's demand-responsive service data, we compare the productivity and service levels among three organizational structures: zoning with transfer, zoning without transfer, and no-zoning designs.
The results indicate that zoning with transfer can provide significant benefits to paratransit operations that manage zoning structure; however, the no-zoning strategy used by Houston METRO (a relatively low-density region) performs better on average in terms of efficiency. This study concludes that the zoning with transfer method can be proven to be a productive organizational structure.

▼ With the advent of OFDM for WLAN communications, as exemplified by IEEE 802.11a, it has become imperative to have efficient and reliable synchronization algorithms for OFDM WLAN receivers. The main
challenges with synchronization deal with the delay spread and frequency offset introduced by the wireless channel. In this work,
rigorous research is done into OFDM WLAN synchronization algorithms, and a thorough synchronizer implementation is presented. This synchronizer performs packet detection, frequency offset estimation, and time offset estimation. Competing timing offset estimation algorithms are compared under a variety of channel conditions, with
varying delay spreads, frequency offsets, and channel SNR. The metrics used to select between competing algorithms are statistical variance, and incremental hardware complexity. The timing offset estimation
algorithms chosen are a dropoff detection algorithm for coarse timing offset estimation, and a quantized cross-correlator with a maximum detector for fine timing offset estimation.

▼ With the advent of multicore processors, there is an increasing amount of interest in building concurrent applications capable of fully utilising their features. Developing applications for these platforms to take full advantage of the power of multicore capabilities remains a complex, error-prone, and challenging endeavour. Unfortunately, concurrency is not uniformly and externally expressed in most existing application models. The result is that concurrency and thread management are hidden within objects or components and intermixed with their functionalities. After demonstrating the tangling of code that results from the interaction of these two major concerns, this thesis describes a method of improving the concurrent program by applying a novel technique to separate the concerns: aspect-oriented programming, which aims to encapsulate concerns that crosscut the main program flow in separate entities into aspects. The most mature aspect-oriented tool available at the time this project was being undertaken is AspectJ, which is an extension of Java. AspectJ can be used to write an aspect to a separate concern in a sequential program to avoid code tangling, but it is often inapplicable for concurrent programs. The problem lies in the fact that the points where parallelisation should occur are not natural join points in AspectJ (i.e. points where AspectJ can intervene). Consequently, this thesis proposes a set of fine-grained join points capable of completely handling concurrent programs. This model goes beyond present AspectJ models and demonstrates the need to recognise complex behaviour for an effective separation of concerns. Finally, aspects for implementing concurrent programs according to different schemes are presented, together with evaluation results. This highlights the flexibility of aspects for implementing concurrent programs, a flexibility which is always a cross-cutting concern with respect to the main concern of base applications.

▼ Time and timing is everything and everywhere from catching a train to synchronizing machines in a production hall. The key issue of all communicating systems is synchronization. Today’s sensor networks are growing larger and more complex every day, creating a demand for simple and scalable networks, whereby data and clock distribution is shared by means of one single interface. High end systems like PET scanners demand a high level of synchronization up to 50 picoseconds or less. This thesis focuses on highly accurate, sub nanosecond synchronization of system clocks for large sensor networks using a single interface for both high speed data communication and clock distribution. In this work different technologies for frequency matching, phase steering and phase measurement for FPGA implementations are compared. The verification and optimization of today’s best technology is presented, including a novel Wheatstone based technique.

▼ In this research the influence of the rower behavior and rigging setup on the boat performance is investigated in a data-driven model. There are different rowing styles and techniques between rowers. Making rowers row in synchrony, while important for the boat performance, is not easy. Rowers have their own signature rowing curve, of which only few aspects can be changed. The signature rowing curve can be based on the oar angle or the relative displacement of the rower. The latter is assumed to be constant for changes in the rigging setup and therefore preferred. The data used in this study comes from a woman’s double, the rowers of which are members of the KNRB. In the boat measurements are done on the gate and foot forces, as well as the oar angles, the seat displacement and boat accelerations. From the free body diagrams of the different parts of the system, a one-dimensional rowing model is derived. The model is driven with the measured forces on the rower and the oar angles. It can be validated with the measured boat accelerations. The distribution of the masses in the system are slightly changed. All drag force on the system is assumed to be viscous and is assumed to be proportional to the square of the boat velocity. The lateral forces on the blade and the oar deformation are neglected. The relative motions of the rower are best predicted with the forces acting directly on the rower, after a compensation of the measured foot force. The best fit for the boat accelerations are found by combining the system acceleration with the relative accelerations of the rowers. With the assumption that the rower can be modeled as a force constraint model, the rigging setup of the modeled boat is changed. The blade forces have a leading role on the resulting boat motions when changing the rigging parameters. However the blade forces might not be realistically modeled. Changing the lever ratio of the oar, by increasing the inboard length leads to a bigger covered oar angle and a higher boat velocity, but a lower work per stroke applied on the handle by the rower. Moving the footstretcher towards the bow of the boat shifts the oar angle and leads to a higher boat velocity and lower handle work per stroke as well. Changing individual rigging parameters did not result in big differences between the rowers. No indications of improved
synchronization between the rowers are found and the energy balance of the system is disrupted. The model simplifications of the blade forces may not be justified. After implementation of a more complex modeling of the blade forces indications of the
synchronization might be found.

▼ Clock
synchronization is one of fundamental requirements in distributed networks. However, the imperfection of crystal oscillators is a potential hurdle for network-wide collaboration and degrades the performance of cooperative applications. Since clock discrepancy among nodes is inevitable, many software and hardware attempts have been introduced to meet
synchronization requirements. Most of the attempts are built on communication protocols that demand timestamp exchanges to improve
synchronization accuracy or resource efficiency. However, link delay and environmental changes sometimes impede these
synchronization efforts that achieve in desired accuracy.
First, the clock
synchronization problem was examined in networks where nodes lack the high accuracy oscillators or programmable network interfaces some previous protocols depend on. Next, a stochastic and practical clock model was developed by using information criteria which followed the principle of Occam's razor. The model was optimized in terms of the number of parameters. Simulation by using real measurements on low-powered micro-controllers validated the derived clock model. Last, based on the model, a clock tracking algorithm was proposed to achieve high
synchronization accuracy between unstable clocks. This algorithm employed the Kalman filter to track clock offset and skew. Extensive simulations demonstrated that the proposed
synchronization algorithm not only could follow the clock uncertainties shown in real measurements but also was tolerant to corrupted timestamp deliveries.
Clock oscillators are vulnerable to noises and environmental changes. As a second approach, clock estimation technique that took circumstances into consideration was proposed. Through experiments on mobile devices, the obstacles were clarified in
synchronization over wireless networks. While the causes of clock inaccuracy were focused on, the effect of environmental changes on clock drifting was investigated. The analysis of the observations inspired an M-estimator of clock error that was accurate but under dominant disturbances such as oscillator instability and random network delay. A Kalman filter was designed to compensate with temperature changes and estimate clock offset and skew. The proposed temperature-compensated Kalman filter achieved the better estimates of clock offset and skew by adjusting frequency shifts caused by temperature changes.
The proposed Kalman filter-based clock
synchronization was implemented in C. A real-time operation was proved by clock tracking between two mobile platforms that the
synchronization technique was implemented on. Moreover, the technique was converted to fixed-point algorithm, which might degrade performance, to evaluate the synchronizing operation on fixed-point processors. The fixed-point simulation reported performance degradation caused by limited hardware resources; however, it also corroborated the applicability of the
synchronization technique.

▼ The ability to measure location using time of flight in IEEE 802.11 networks is impeded by the standard clock resolution, imprecise
synchronization of the 802.11 protocol, and the inaccuracy of available clocks. To achieve real-time location with accuracy goals of a few meters, we derive new consensus
synchronization techniques for free-running clocks. Using consensus
synchronization, we improve existing time of arrival (TOA) techniques and introduce new time difference of arrival (TDOA) techniques. With this common basis, we show how TOA is theoretically superior to TDOA. Using TOA measurements, we can locate wireless nodes that participate in the location system, and using TDOA measurements, we can locate nodes that do not participate. We demonstrate applications using off-the-shelf 802.11 hardware that can determine location to within 3m using simple, existing optimization methods. The
synchronization techniques extend existing ones providing distributed
synchronization for free-running clocks to cases where send times cannot be controlled and adjusted precisely, as in 802.11 networks. These location and
synchronization techniques may be applied to transmitting wireless nodes using any communication protocol where cooperating nodes can produce send and receive timestamps.

▼ Prokaryotic cyanobacteria have been studied as the simplest organisms that exhibit circadian rhythms. The central S.elongatus clock is comprised of at least three components, the proteins KaiA, KaiB and KaiC. The phosphorylation status of KaiC can sustain a ca. 24-hour period in vitro with the presence of the two other Kai proteins and ATP.
Synchronization of different oscillators can be achieved by mixing two KaiABC in vitro samples that are in different phosphorylation phases, with prior results indicating that their rhythms continue, yet with a synchronized shared phase. I have focused on investigating the
synchronization of oscillators with different periods in vivo and in vitro with the goal of elucidating the underlying mechanisms. Interdisciplinary approaches including molecular biology, biochemistry and computational simulation are combined to demonstrate that co-existence of two oscillators with different periods displays a robustly synchronized rhythm with an intermediate period both in vivo and in vitro. Moreover, the computationally simulated results agree with the in vitro experiment, and imply that monomer exchange may work together with KaiA sequestration to secure the molecular
synchronization of KaiC population in the in vitro reaction.

▼ Understanding how the transmission of energy between the providers (such as nuclear power stations, renewable resources, or any type of supplying entity) and the consumers (such as factories, homes, or any type of demanding entity) depends on the structure of the inter-connections between them and on their dynamical be- haviour, is of paramount importance for the design of power-grid systems that are resilient to failures, e.g., failures due to structural modifications or energy fluctu- ations. In this thesis, we derive the implicit relationship between structure and behaviour that flow and power networks have, namely, the mathematical principles behind the transmission of energy in complex networks. From our novel derivations, we determine exact and approximate strategies to create self-controlled and stable systems (i.e., resilient to failures without the need for external controllers) that have an optimal (i.e., with less cost and power dissipation) and smart (i.e., allowing the decentralisation of large power-stations to smaller fluctuating renewable resources) energy distribution. Moreover, not only we achieve analytical solutions for problems that usually require a numerical analysis, but we also propose a change in the analy- sis view-point of complex systems, namely, systems composed of many dynamically interacting units forming a network. We show that in order to explain the emer- gent behaviour in these systems, instead of focusing on the network structure of the interactions, we should focus on the functional form of the interactions. In particu- lar, we derive a general framework to study the existence and stability of emergent collective behaviour in networks of interacting phase-oscillators, namely, the math- ematical principles behind the synchronisation in complex networks. The numerous breakthrough results in this thesis are expected to be of aid for engineers to design smarter and more resilient power-grid systems, as well as to scientists dealing with emergence of collective behaviour in complex systems.

▼ In this thesis, a blind symbol timing
synchronization algorithm based on cyclic prefix for OFDM systems in multipath fading channels is proposed. It finds the starting point of symbol timing for using appropriate weights which are designed from channel delay spread characteristics. In multipath fading channels, the conventional ML (maximum likelihood) algorithm estimate is biased and has a large variance due to the effect of channel delay spread. The proposed exponential weighting methods not only solve the above problems but also improve the accuracy of symbol timing. Particularly, the proposed method does not require the information of SNR and channel length. From computer simulation results, the proposed method outperforms the other conventional algorithms and is also robust against the effect of multipath fading channels.

▼ FPS is a more general form of synchronization. Hyperchaotic systems possessing
more than one positive Lypaunov exponent exhibit highly complex behaviour and
are more suitable for some applications like secure communications. In this thesis
we report studies of FPS and MFPS of a few chaotic and hyperchaotic systems.
When all the parameters of the system are known we show that active nonlinear
control method can be efectively used to obtain FPS. Adaptive nonlinear control
and OPCL control method are employed for obtaining FPS and MFPS when some or
all parameters of the system are uncertain. A secure communication scheme based
on MFPS is also proposed in theory. All our theoretical calculations are verified by
numerical simulations.
