With human society becoming increasingly computerised, the use of biometrics to automatically establish the identity of an individual is of great interest in a wide variety of applications. Facial appearance is an appealing biometric, on account of its relatively non-intrusive nature. As such, automated face recognition systems have been the subject of much research in recent years. This dissertation describes the development of a fully automatic face recognition system, and provides an analysis of its performance under various di erent operating conditions, in comparison with results published in prior literature. In addition to giving a detailed description of the mathematical underpinnings of the techniques used by the system, we discuss the practical considerations involved in implementing the described techniques. The system presented here uses the eigenface approach to representing facial features. A number of di erent recognition techniques have been implemented and evaluated. These include a number of variants of the original eigenface technique proposed by Turk and Pentland, as well as a related technique based on the probabilistic approach of Moghaddam et al. Due to the wide range of datasets used to evaluate face recognition systems in the literature, it is di cult to reliably compare the performance of di erent systems. The system described here has been tested with datasets encompassing a wide range of di erent conditions, allowing us to draw conclusions about how the characteristics of the test data a ect the results that are obtained. The performance of this system is comparable to other eigenface-based systems documented in the literature, achieving success rates in the region of 85% for large datasets under controlled conditions. However, performance was observed to degrade signi cantly when testing with more free-form images; in particular, the e ects of ageing on facial appearance were noted to cause problems for the system. This suggests that the matter of ageing is still a fruitful direction for further research. / Thesis (M.Sc.)-University of KwaZulu-Natal, Westville, 2012.

<p> The general purpose of this work is to study the feasibility of using McMaster University's PACER and MACSIM Executive Computer Programmes to simulate the environmental control system in a large building by means of elementary modules. </p> <p> The operation of PACER is described together with some general instructions as to its use. </p> <p> A number of module subroutines are developed, covering a wide cross-section of the type of equipment used in the air conditioning, heating and ventilation of a building. They are used in various combinations within the main programme to demonstrate their use. The programmes developed are not sufficient to simulate a complex system; however, they would act as a guide to the user for developing the necessary programmes to enable him to represent almost any type of equipment. </p> / Thesis / Master of Engineering (ME)

This report presents a study of the basic criteria for computer programmes that may be consideredadequate for aiding children with autism in their education and upbringing. I have based thisstudy on descriptions, opinions and proposals from people who deal with treatment and/orother issues concerning children with autism, as well as relevant literature.The study has been carried out in a major Swedish metropolitan municipality. The intervieweeswere civil servants from this municipality and representing different institutional endeavourson the issue of autism.I used a combination of both quantitative and qualitative techniques, as there was need for bothstandardization and qualitative variation. The main aim of the study was to seek suggestionson how computer programmes should be. That is, if they are to be considered appropriate föraiding children with autism develop their personality.The general conclusion of this study is that computer programmes, that may be consideredappropriate for the above mentioned purpose, should have certain characteristics of whichpedagogic usefulness and user suitability are of primary importance.

Changes in climate due to anthropogenic influences are expected to affect both hydrological and agricultural systems in southern Africa. Studies on the potential impacts of climate change on agrohydrological systems had been performed previously in the School of Bioresources Engineering and Environmental Hydrology (School of BEEH). However, refinement of these modelling tools and restructuring of the databases used was needed to enable more realistic and dynamic simulations of the impacts of changes in climate. Furthermore, it was realised that modifications and linkages of various routines would result in a faster processing time to perform climate impact assessments at the catchment scale. Baseline ("present") climatic information for this study was obtained from the School of BEEH's database. Scenarios of future climate were obtained from six General Circulation Models (GCMs). Output from the five GCMs which provided monthly climate output was used in the climate impact assessments carried out. Potential changes in variability of rainfall resulting from climate change was assessed using the daily climate output from the sixth GCM. As the spatial resolution of the climatic output from these GCMs was too coarse for use in climate impact studies the GCM output was interpolated to a finer spatial resolution. To assess the potential impact of climate change on water resources in southern Africa the ACRU hydrological modelling system was selected. The ACRU model was, however, initially modified and updated to enable more dynamic simulation of climate change. In previous hydrological studies of climate change in southern Africa Quaternary Catchments were modelled as individual, isolated catchments. To determine the potential impact of changes in climate on accumulated flows in large catchments the configuration of the Quaternary Catchments needed to be determined and this configuration used in ACRU. The changes in hydrological responses were calculated both as absolute differences between future and present values and the ratio offuture hydrological response to the present response. The large degree of uncertainty between the GCMs was reflected in the wide range of results obtained for the water resources component of this study. In addition to the climate impact studies, sensitivity and threshold studies were performed using ACRU to assess the vulnerability of regions to changes in climate. Potential change in the yields and distributions of parameters important to agriculture, such as heat units, crops, pastures and commercial tree species were assessed using simple crop models at a quarter ofdegree latitude / longitude scale. Most species were simulated to show decreases in yields and climatically suitable areas. There are many sources of uncertainties when performing climate impact assessments and the origins of these uncertainties were investigated. Lastly, potential adaptation strategies for southern Africa considering the results obtained are presented. / Thesis (Ph.D.)-University of Natal, Pietermaritzburg, 2001.

Copyright Protection and the Use of Computer Programmes Abstract In this diploma thesis, the author deals with copyright protection and the use of computer programmes. The aim of the work is to create the most comprehensive overview of the substantive law protection of computer programmes, including issues of use of a computer program by persons other than its author. The work is divided into three parts. The first, most extensive part (chapters 1-7) is devoted to the mentioned comprehensive overview of the substantive regulation of copyright protection of computer programmes. Part of this part is a short excursion into the history of computer programmes and related principles of legislation at the international and European level. The following is the definition of a computer program, including a brief explanation of how computer programs are created and what their functionality is. After that, the author deals in detail with the rights that are created to the software author by creating the software, always on specific cases from practice. The following is the issue of granting and exercising copyright in software, if it is created by a larger group of people who may act in different legal relationships. The sixth chapter discusses in detail the possibilities of using computer programmes by people other...

This study explores the possible use of digital media as an effective psychotherapeutic aid in art psychotherapy, specifically in addressing the effects of trauma experienced by adolescents. A literature review provides evidence on what exactly can be understood under the concepts 'art psychotherapy' and 'digital media'. The literature study further investigates trauma, its treatment and how art psychotherapy can be used as a psychotherapeutic tool with adolescents who have been exposed to trauma. An empirical study including six participants, chosen through a specific sampling process, and whose background information regulates the appropriate methods of intervention demonstrates the practicality of digital media in art psychotherapy. Data gathered from pre-assessment activities, art psychotherapy sessions and post-assessment activities are analysed, interpreted, and reduced through a systematic process. The empirical findings are then presented in a detailed, concise manner From the empirical investigation, it is determined that digital media can be used as a successful tool in art psychotherapy, specifically with adolescents who have experienced trauma. The researcher gained experience in the implementation of digital media in art psychotherapy and was able to provide valuable information about this practice, specifically for professionals interested in the field of art psychotherapy. The researcher was also able to identify limitations and further areas for research in this field. / Psychology of Education / M. A. (Guidance and Counselling)--University of South Africa --2013

Thesis (D. Tech. (Engineering: Electrical)) -- Central University of technology, Free State, 2012 / This thesis describes a method for the automatic generation of appli- cation speci_c processors. The thesis was organized into three sepa- rate but interrelated studies, which together provide: a justi_cation for the method used, a theory that supports the method, and a soft- ware application that realizes the method. The _rst study looked at how modern day microprocessors utilize their hardware resources and it proposed a metric, called core density, for measuring the utilization rate. The core density is a function of the microprocessor's instruction set and the application scheduled to run on that microprocessor. This study concluded that modern day microprocessors use their resources very ine_ciently and proposed the use of subset processors to exe- cute the same applications more e_ciently. The second study sought to provide a theoretical framework for the use of subset processors by developing a generic formal model of computer architecture. To demonstrate the model's versatility, it was used to describe a number of computer architecture components and entire computing systems. The third study describes the development of a set of software tools that enable the automatic generation of application speci_c proces- sors. The FiT toolkit automatically generates a unique Hardware Description Language (HDL) description of a processor based on an application binary _le and a parameterizable template of a generic mi- croprocessor. Area-optimized and performance-optimized custom soft processors were generated using the FiT toolkit and the utilization of the hardware resources by the custom soft processors was character- ized. The FiT toolkit was combined with an ANSI C compiler and a third-party tool for programming _eld-programmable gate arrays (FPGAs) to create an unconstrained C-to-silicon compiler.
