Demands for seamless mobile communications are driving the research and development of software defined radio (SDR), which enables a single terminal to transmit and receive in distinct wireless systems through a simple change in software to reconfigure the terminal's functions. Its application areas include military use, home networks, intelligent transport systems and cellular communications. Several SDR software architectures have been developed during the last few years. One implementation of the Software Communications Architecture is the Open Source SCA Implementation

The primary purpose of this paper is to analyze and evaluate a relatively recently proposed statistic, "Duncan's New Multiple Range Test," for use when the researcher's plans call for a test of significance between three or more group means.

Mathematicians and computational scientists are often limited in their ability to model complex phenomena by the time it takes to run simulations. This thesis will inform interested researchers on how the development of highly parallel computer graphics hardware and the compiler frameworks to exploit it are expanding the range of algorithms that can be explored on affordable commodity hardware. We will discuss the complexities that have prevented researchers from exploiting advanced hardware as well as the obstacles that remain for the non-computer scientist.

The need for sensor-based automatic motion planning and control of industrial robots in an unstructured environment is extensive. For example in-factory transportation, household chores, military applications, chemical, radioactive, and other applications dangerous to humans. Researchers are attempting to build systems capable of generating purposeful motion in highly uncertain co-nplex environments, using on-line information from robot sensors. An example of such a task would be moving a mobile robot or a manipulator arm from its starting position to a goal position in a scene with unknown arbitrarily shaped obstacles. Carrying out such tasks requires, first, sensors and related / GR2017

A dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science. Johannesburg, 2014. / This thesis aims to provide a summary on computational approaches to solving the Compressed Sensing problem. The theoretical problem of solving systems of linear equations has long been investigated in academic literature. A relatively new field, Compressed Sensing is an application of such a problem. Specifically, with the ability to change the way in which we obtain and process signals. Under the assumption of sparse signals, Compressed Sensing is able to recover signals sampled at a rate much lower than that of the current Shannon/Nyquist sampling rate. The primary goal of this thesis, is to describe major algorithms currently used in the Compressed Sensing problem. This is done as a means to provide the reader with sufficient up to date knowledge on current approaches as well as their means of implementation, on central processing units (CPUs) and graphical processing units (GPUs), when considering computational concerns such as computational time, storage requirements and parallelisability.

The purpose of this study was to develop and evaluate two instructional presentations of flowcharting and computer programming to prospective elementary school teachers. In general, the two instructional approaches differed in the amount of pedagogical subject matter which was integrated into the computer programming content. The control treatment contained no pedagogical content. The subjects (n-38) of the study were students enrolled in a regular CUPM-type course for prospective elementary school teachers. The study was designed to test six hypotheses stated in the null form. In addition, an analysis of the subjects' critiques of a videotaped sixth grade lesson was made. The results of the study suggest that pedagogical subject matter and BASIC computer programming, integrated in a course for prospective elementary school teachers, can cause significant improvements in retention of, and attitudes toward, computer programming. Furthermore, the quality of lesson plans can be enhanced by this integration--Abstract. / Typescript. / "June, 1975." / "Submitted to the Area of Instructional Design and Personnel Development, Program of Mathematics Education, in partial fulfillment of the requirements for the degree of Doctor of Philosophy." / Advisor: Eugene D.
