Variable sampling compensation of networked control systems with delays using neural networks

Creator:: Lopez-Echevarria, Daniel
Abstract:: In networked control systems (NCS) information or packets usually flow from a sensor or a set of sensors to a remotely located controller. Then the controller processes the received information and sends a series of control commands to the actuators through a communication network which could be either wireless or...

The dynamic speculation and performance prediction of parallel loops

Creator:: Zier, David A.
Abstract:: General purpose computer systems have seen increased performance potential through the parallel processing capabilities of multicore processors. Yet this potential performance can only be attained through parallel applications, thus forcing software developers to rethink how everyday applications are designed. The most readily form of Thread Level Parallelism (TLP) within any...

Task partitioning and scheduling on arbitrary parallel processing systems

Creator:: El-Rewini, Hesham
Abstract:: Parallel programming is the major stumbling block preventing the parallel processing industry from quickly satisfying the demand for parallel computer software. This research is aimed at solving some of the problems of software development for parallel computers. ELGDF is a graphical language for designing parallel programs. The goal of ELGDF...

Target-based coverage extension of 802.11 MANETs via constrained UAV mobility

Creator:: Johnson, Taylor N.
Abstract:: MANETs are known to be useful in situations where mobile nodes need to communicate and coordinate in dynamic environments with no access to fixed network infrastructure. However, connectivity problems can occur when sub-groups within a MANET move out of communication range from one another. The increasingly prolific use of UAVs...

Software composition with extended entity-relationship diagrams

Creator:: Muenchaisri, Pornsiri
Abstract:: I introduce a compositional approach to application software development. In this approach, an extended entity-relationship diagram (EERD), which represents the component types and the relationship types within an application domain, is used as a template of executable programs in that application domain. As we use structural active objects as the...

Security protocols for linear network coding

Creator:: Adeli, Majid
Abstract:: Network coding, as the next generation of data routing protocols, enables each intermediate node in a network to process and encode its received data before forwarding it to the next nodes. Hence, the core idea in network coding is to allow a network to encode the data that is being...

Scheduling system of affine recurrence equations by means of piecewise affine timing functions

Creator:: Mui, Lap K.
Abstract:: Many systematic methods exist for mapping algorithms to processor arrays. The algorithm is usually specified as a set of recurrence equations, and the processor arrays are synthesized by finding timing and allocation functions which transform index points in the recurrences into points in a space-time domain. The problem of scheduling...

Protocol design and optimization for wireless networks

Creator:: Lertsutthiwong, Monchai
Abstract:: We investigate a number of techniques for increasing throughput and quality of media applications over wireless networks. A typical media communication application such as video streaming imposes strict requirements on the delay and throughout of its packets, which unfortunately, cannot be guaranteed by the underlying wireless network due inherently to...

Parallel simplex algorithms and loop spreading

Creator:: Wu, Youfeng
Abstract:: Parallel solutions for two classes of linear programs are presented. First we parallelized the two-phase revised simplex algorithm and showed that it is possible to get linear improvement in performance. The simplex algorithm is the best known algorithm for solving linear programs, and we claim our result is the best...

Optimizing the advanced encryption standard on Intel's SIMD architecture

Creator:: Godbole, Pankaj
Abstract:: The Advanced Encryption Standard (AES) is the new standard for cryptography and has gained wide support as a means to secure digital data. Hence, it is beneficial to develop an implementation of AES that has a high throughput. SIMD technology is very effective in increasing the performance of some cryptographic...
