Creator: SINIBALDI, JOHN CLAUDE., Florida Atlantic University, Marcovitz, Alan B., College of Engineering and Computer Science, Department of Computer and Electrical Engineering and Computer Science
Abstract/Description: A comparative analysis of two methods of bus arbitration used by a multiprocessing system with a single main bus is performed. The major performance parameters are delay time and the average number of active processors, called processing power. The bus arbitration methods are described using state and timing diagrams. Multiprocessor systems using these methods of arbitration are then modeled using Markov chains to enable the formulation of processing power. From processing power other...
Show moreA comparative analysis of two methods of bus arbitration used by a multiprocessing system with a single main bus is performed. The major performance parameters are delay time and the average number of active processors, called processing power. The bus arbitration methods are described using state and timing diagrams. Multiprocessor systems using these methods of arbitration are then modeled using Markov chains to enable the formulation of processing power. From processing power other performance parameters can be derived. A comparison is then made among the two bus arbitration methods based on the analytical results where processors access the bus at an equal rate. Simulations of multiprocessor systems using either of the two arbitration methods were performed to validate the analytical models for equal bus request rates. Simulations are also performed of a system of processors using the main bus at unequal rates.

Show moreThe subject of this thesis is the design and implement at ion of an expert system from a standard data base management software language. The advantages and limitations of such a system design are discussed and supported by an accompanying implementation. Both, the design and implementation, demonstrate what gives the expertise or personification of human reasoning to a machine and why this type of reasoning is well suited to certain types of problems. This fundamental departure from traditional deterministic analytical problem solving is accomplished by developing a system that is heuristic in nature. This heuristic implementation provides for a system that assists in the development of an emerging solution, rather than a deterministic solution in and of itself (i.e., a system that is programmed with a set of meta-knowledge rules that governs the decision making process and acts upon a second set of knowledge rules).

Title: SHINE: An integrated environment for software hardware co-design.
Creator: Jayadevappa, Suryaprasad., Florida Atlantic University, Shankar, Ravi, College of Engineering and Computer Science, Department of Computer and Electrical Engineering and Computer Science

Show moreThe rapid evolution of silicon technology has brought exponential benefits in cost, scale of integration, power per function, size per function and speed. The ability to place multiple function "systems" on a single silicon chip, reduce development cycle while increasing product functionality, performance and quality. With this increased complexity, ability to model at high level of abstraction becomes crucial. Also, the fact that no known existing complete system on chip design packages with perfect tools, models, and formalisms further slows down and complicates the development. This dissertation provides an integrated environment for hardware software co-design at a high level of abstraction. We have developed a SystemC based cockpit for this purpose. The cockpit, known as SHINE consists of many components including architectural components, operating system components, and application software components. The ability to represent and manipulate these components at high levels of abstraction is a major challenge. To address these challenges we have developed a set of principles. Important principles evolved are synergy of separation of concerns, reusability, flexibility, ease of use, and support for multiple levels of abstraction. 'Synergy of Separation of Concerns' helps in maintaining transparency during all instances in the development of the integrated environment. One application is transparent to another application and in turn to the system architecture. Also in the system architecture, each module is designed independent of other modules. Well defined interfaces enable this transparency and easier to integrate. This also enhances component reuse and overall design environment modularity. 'Ease of Use' allows the user to shorten the learning curve involved. In SHINE, 'Flexibility' is addressed via support for plug-and-play of components in the design environment. We provide results to show the implementation of these principles. SHINE provides a cost-effective mechanism to develop a system co-design infrastructure. This will lead to early system verification and performance estimation resulting in shorter time-to-market. The design flow developed is structured and is easily extended. This is an exploratory study that is the result of a long term industrial collaboration to enhance design productivity. Significantly more work lies ahead in developing an industry standard tool and methodology.

The second was the design of a cheap, portable system to detect phosphorus in water. This system could not be completed due to time constraints, but the methods were detailed, and design ideas were laid out for future work.

Show moreMicromixer is one of the most significant components of microfluidic systems, which manifest essential applications in the field of chemistry and biochemistry. Achieving complete mixing performance at the shortest micro channel length is essential for a successful micromixer design. We have developed five novel micromixers which have advantages of high efficiency, simple fabrication, easy integration and ease for mass production. The design principle is based on the concept of splitting-recombination and chaotic advection. Numerical models of these micromixers are developed to characterize the mixing performance. Experiments are also carried out to fabricate the micromixers and evaluate the mixing performance. Numerical simulation for different parameters such as fluids properties, inlet velocities and microchannel cross sectional sizes are also conducted to investigate their effects on the mixing performance. The results show that critical inlet velocities can be predicted for normal fluid flow in the micromixers. When the inlet velocity is smaller than the critical value, the fluids mixing is dominated by mechanism of splitting-recombination, otherwise, it is dominated by chaotic advection. If the micromixer can tolerate higher inlet velocity, the complete mixing length can be further reduced. Our simulation results will provide valuable information for engineers to design a micromixer by choosing appropriate geometry to boost mixing performance and broaden implicational range to fit their specific needs. Accurate and complicated fluidic control, such as flow mixing or reaction, solution preparation, large scale combination of different reagents is also important for bio-application of microfluidics. A proposal microfluidic system is capable of creating 1024 kinds of combination mixtures. The system is composed of a high density integrated microfluidic chip and control system. The high density microfluidic chip, which is simply fabricated through soft lithography technique, contains a pair of 32 flow channels that can be specifically addressed by each 10 actuation channels based on principle of multiplexor in electronic circuits. The corresponding hardware and software compose the control system, which can be easy fabricated and modified, especially for prototype machine developing. Moreover, the control system has general application. Experiments are conducted to verify the feasibility of this microfluidic system for multi-optional solution combination.

Show moreThis document reports on a hands-on project aimed at learning and experiencing the concept of system-of-systems. The motivation behind this project is to study and implement the concept of System of Systems in the generation of a RF-based communication and control complex system. The goal of this project is to develop a multi-level integrated and complete system in which the vehicles that belong to a same network can become aware of their location, communicate with nearby vehicles (sometimes with no visible line of sight), be notified of the presence of different objects located in their immediate vicinity (obstacles, such as abundant vehicles), and generate a two dimensional representation of the vehicles’ location for a remote user. In addition, this system will be able to transmit back messages from the remote user to a specific or to all local vehicles. The end result is a demonstration of a complex, functional, and robust system built and tested for other projects to use and learn from.

Show moreThe ever increasing demand for capacity in wireless cellular networks is resolved by decreasing the size of the cells. The smaller cells created inside large cells are called microcells and they cover smaller and dense areas. As a result of this, the mobile device ends up changing the base stations or performing handover at a much higher rate. To maintain the reliability and quality of the call, it is obligatory to ascertain that the handover is performed at a proper location. If the handover is delayed or the mobile handset drags its base station, it is more probable that either the call will drop or the quality of the call will be compromised. The last thing a mobile handset user would want is to experience any of these two consequences. In this thesis we study the methods to analyze the performance ofhandover by the mobile handsets in the drive setup under test. This thesis presents a model for analyzing the performance ofhandoffbased on the measurements ofthe received signal strength indicator and the color code recorded by the mobile handset in the drive test field path. The model from the simulations is seen to yield results that agree with other research about the performance of mobile handsets.

Show moreOne of the main applications of machine learning in bioinformatics is the construction of classification models which can accurately classify new instances using information gained from previous instances. With the help of machine learning algorithms (such as supervised classification and gene selection) new meaningful knowledge can be extracted from bioinformatics datasets that can help in disease diagnosis and prognosis as well as in prescribing the right treatment for a disease. One particular challenge encountered when analyzing bioinformatics datasets is data noise, which refers to incorrect or missing values in datasets. Noise can be introduced as a result of experimental errors (e.g. faulty microarray chips, insufficient resolution, image corruption, and incorrect laboratory procedures), as well as other errors (errors during data processing, transfer, and/or mining). A special type of data noise called class noise, which occurs when an instance/example is mislabeled. Previous research showed that class noise has a detrimental impact on machine learning algorithms (e.g. worsened classification performance and unstable feature selection). In addition to data noise, gene expression datasets can suffer from the problems of high dimensionality (a very large feature space) and class imbalance (unequal distribution of instances between classes). As a result of these inherent problems, constructing accurate classification models becomes more challenging.

With difficulties such as high dimensionality, class imbalance, noisy data, and difficult to learn class boundaries, being present within the data, bioinformatics datasets are a challenge to work with. One potential source of assistance is the domain of data mining and machine learning, a field which focuses on working with these large amounts of data and develops techniques to discover new trends and patterns that are hidden within the data and to increases the capability of researchers and practitioners to work with this data. Within this domain there are techniques designed to eliminate irrelevant or redundant features, balance the membership of the classes, handle errors found in the data, and build predictive models for future data.

Show moreMicroelectromechanical systems (MEMS) accelerometers and gyroscopes are small scale sensors that measure changes in linear acceleration and rotational velocity, respectively. They are fabricated using electronic circuit techniques such as etching and deposition. MEMS motion sensors can be used in an Inertial Measurement Unit (IMU) that can be integrated with the Global Positioning System (GPS) to make a navigation system that is more accurate than each system alone. However, since MEMS-based IMUs are inherently noisy, we must overcome inaccuracies caused by the integration of random noise to find position. Accuracy can be increased by applying digital filters to the data before integration. Comparing the success of finite impulse response (FIR) filters and infinite impulse response (IIR) filters, we found that even though our highest order FIR filter yielded the most accurate position, it was limited by an offset bias in the accelerometer signal and a time delay in the determined position.

Show moreCurrent multicore processors attempt to optimize consumer experience via task partitioning and concurrent execution of these (sub)tasks on the cores. Conversion of sequential code to parallel and concurrent code is neither easy, nor feasible with current methodologies. We have developed a mapping process that synergistically uses top-down and bottom-up methodologies. This process is amenable to automation. We use bottom-up analysis to determine decomposability and estimate computation and communication metrics. The outcome is a set of proposals for software decomposition. We then build abstract concurrent models that map these decomposed (abstract) software modules onto candidate multicore architectures; this resolves concurrency issues. We then perform a system level simulation to estimate concurrency gain and/or cost, and QOS (Qualify-of-Service) metrics. Different architectural combinations yield different QOS metrics; the requisite system architecture may then be chosen. We applied this 'middle-out' methodology to optimally map a digital camera application onto a processor with four cores.
