Quality of service differentiation has never achieved much attention and relevance until the advent of the convergence of mobile wireless network and the fixed Internet, that is, Internet Protocol ( IP ) based mobile wireless networks, or wireless Internet. These networks are poised to support multimedia applications ' traffic with diverse QoS sensitivities. To date, most traffic transferred over the Internet still undergo best - effort forwarding, which does not guarantee whether or not traffic sent by a source gets to the intended destination, let alone loss and timing bounds. The major contribution of this thesis is three - fold. First, the thesis proposes a QoS - enabled wireless Internet access architecture, which leverages the micromobility in wireless standards to reduce mobile IP weaknesses, such as long handoff delay, to achieve effective interworking between mobile wireless networks and the global, fixed Internet. Although the idea here is applicable to any wireless standard, the design examples in this thesis are based on the IEEE 802.11b wireless local area network ( WLAN ) standard. Second, it proposes a framework for a class of wireless channel state dependent packet scheduling schemes, which consider the QoS requirements of the applications ' traffic ; the wireless channel state ( reflected in instantaneous data rate or noise level ) ; and optimises the usage of the expensive wireless resource. The operation of the QoS - enabled, channel state - dependent packet scheduler is analysed using optimisation theory, eigenanalysis and stochastic modelling. Third, the thesis analyses the effects of wireless channel properties on differentiated QoS ( DQoS ) schemes, using two - dimensional, channel - state - dependent queuing theory, matrix analytic methods to stochastic modelling and eigenanalysis. The ana - lytical model of DQoS schemes, especially models accounting for user scenarios such as speed of motion and wireless channel properties, such as fading, spatio - temporarily varying quality and low rate, is not properly covered in the open literature, and hence was a motivation for this part of the thesis. The wireless channel is discretized into discrete - time Markovian states based on the received signal - to - noise plus interference ratio ( SNIR ), which also reflects on the instantaneous link quality. The link quality, in turn, influences the QoS experienced by the transported applications sitting on top of the ISO / OSI protocol hierarchy. The parameters of the Markovian states are evaluated using realistic physical channel noise models and transceiver characteristics, such as modem. [ Different modems ( modulator / demodulator ) yields different transceiver properties such as sensitivity. The analysis in the thesis adopts QPSKand BPSK modulation. ] Source traffic models are used in the analysis. Lastly, the thesis provides an extensive introduction to, and provides a detailed background material for the new area of mobile wireless Internet systems, upon which considerable future research can be based. / Thesis (Ph.D.)--School of Electrical and Electronic Engineering, 2003.

The South African government like most governments around the world create public entities to perform functions on its behalf and achieve particular objectives ranging from facilitating investments, delivering services or providing goods and advice. These public entities receive annual funding either whole or in part from the national fiscus and report to parliament through their respective Ministries. In the 2005/6 financial year government funded Umalusi 7, 69 million rands through direct transfer payments from the Department of Education, excluding any indirect payments from other governmental structures. Many public entities, about three hundred and thirty odd or so in South Africa, were promulgated to ensure and improve service delivery to the nation. However, they were not intended to be seen as an extension of their reporting departments. This research work evaluates the effectiveness of Umalusi in the education regulatory system and seeks to find ways to improve public entity effectiveness using the South African Excellence Model (SAEM) as the base tool to measure organisational effectiveness. A brief conclusion to this study is that Umalusi as a public entity, is adequately meeting its intended purpose. This is confirmed through its annual reports having never received a qualified audit since its inception. This research triangulates the results of the South African Excellence Model, the Questionnaire to senior education officials and the Auditors' Reports to confirm that Umalusi is effective as a public entity in the South African regulatory system. / Busniness Management / M.Tech.

The aim of this thesis is to find out a way of applying the modern methods of quality control in the industrial company and suggestion of some recommendations for small and medium-sized enterprises. The thesis is composed of theoretical and practical parts. In the theoretical part of this work are compiled notions relevant to the issue. The practical part of the work consists of the results of the analysis of the applied methods of quality controls in the business, which with a kind of a way of service controls the product quality in other businesses. The end of the thesis contains suggestions and recommendations resulting from the practical part.

A dissertation submitted in fulfillment of the requirements for the degree Master Technology: Quality in the Faculty of Engineering at the Cape Penisula University of Technology / Uneven surfaces on national roads that often lead to difficulty and even danger can be extremely hazardous when wet, due to mud and cracks, and also create dust pollution for motorists, pedestrians, residents and business. The continuing use of low quality raw materials in producing hot mix asphalt for national roads, leads to regular maintenance at a very high cost. The quality aggregates (stone that is used to produce asphalt), and the quality of bitumen are often inadequate for the correct composition of hot mix asphalt. The mst important factors affecting initial and long term performance of the highways is the inferior pavement structure and condition, due to poor aggregates (raw material)from suppliers. The performance of asphalt i s largely determined by the characteristics of its constituents, the asphalt binder and aggregates.

Thesis (MTech (Quality))--Cape Peninsula University of Technology, 2016. / The study has been carried out on impact of implementing ISO standards on SMEs to seek general evaluation of its benefits. The purpose of this paper is to outline the benefits of ISO implementation on South African small- and medium-sized enterprises (SMEs). The SME sector is the backbone of developed economies, which is regarded as the engine of growth for economies all over the world. For developing countries, SMEs often offer the only realistic prospects for increases in employment since they employ the largest percentage of the workforce population. With the trend towards global market orientation and trade liberalisation, SMEs are moving towards implementing quality systems. The empirical study aims to explore current implementation of quality management tools and advanced improvement techniques in the Western Cape SMEs, in order to understand what factors impact on how quality control is managed. Two main categories are analysed, namely tangible and intangible. This study will assist other SMEs in developing countries on ISO 9000 implementation. This study is restricted to small and medium-sized companies in South Africa implementing ISO system and other quality tools or techniques. Data collection of this study is done based on a combination of survey questionnaires and interviews with managers, supervisors and general staff.

O método empregado é o da pesquisa-ação. Para tanto, analisa-se uma empresa, na qual o sistema de gestão da qualidade é estruturado e introduzido. Com isso, pretende-se demonstrar de forma sintética uma outra abordagem de implementação do Controle de Qualidade Total, que pode trazer benefícios para a organização desde as etapas iniciais. Para corroborar com esta idéia, além de demonstrar como o método foi empregado na empresa, três estudos de caso são apresentados detalhadamente. Posteriormente, analisam-se como os projetos de melhoria contribuíram para a institucionalização da qualidade total na organização. Concluindo, este trabalho pretende comprovar a hipótese de que o MASP pode ser utilizado para iniciar o movimento da qualidade e auxiliar na implementação do TQC / Abstract: The main goal of this study is to use the QC Story method of problem solving and analysis as a vehicle for the implementation of a total quality program and evaluate its impacts in a company from the packaging sector. The method that was used employs a research in an industry where the quality management system was structured and introduced. This work intents to briefly demonstrate the advantages that the use of this alternative approach may provide, even in its early phases. To emphasize this idea and also to demonstrate how the method was used in the industry being researched, three detailed case studies are presented. After that, it is analyzed how these improvement projects have influenced the institutionalization of the total quality control concepts in the company. At last, this study intents to verify the hypothesis that the QC Story method can be used to start the quality movement and help the TQC implementation / Mestrado / Materiais e Processos de Fabricação / Mestre em Engenharia Mecânica

M.Cur. / The intensive care nurse practising respiratory nursing care, is responsible for giving high quality nursing care. Due to the rising cost of health care more pressure is placed on the nurse to provide a high quality nursing care (Sanazaro, 1986:27) Bruwer (1986:220-245) states that there is a need for an orderly, methodical qua l Ity assurance approach on all nursing levels in South Africa, based on a South African model, as well as the development of nursing standards for public and private hospitals. Mechanical ventilation forms an important part of the nursing of the adult critically ill patient in the intensive care unit. To ensure that the patient benefits from mechanical ventilation and does not suffer from complications due to mechanical ventilation, standards must be developed to ensure the giving of a high quality of nursing care. Without these standards it is impossible to determine the quality of their nursing care given. The quality can furthermore,only be questioned and not be determined scientifically. Standards for providing high quality nursing care to mechanically ventilated patients do not exist in South Africa. The quality of the nursing care that these patients receive is therefore questioned.

M.Com. (Sport Management) / The fact that South Africa is back in the international sports arena, puts a lot of pressure on the South African sportsmen and women. This also gives the South African sports people the opportunity to show the world that they can participate with the best and win. Unfortunately this pressure highlighted some other shortcomings in the South African sports world. Some of these shortcomings are the standard of training, the lack of international exposure, the management of the sport federations and the lack and quality of sport and recreation facilities. The political stance of the past, contributed towards imbalances in sport and recreation in South Africa. The Government of National Unity of South Africa is trying to correct these imbalances. The importance of sport and recreation is reflected in the 1994/1995 budget as well as in the Reconstruction and Development Programme (RDP) of the government. One of these imbalances that is addressed in the providing of sport and recreation facilities to all the communities. The reality however is that the government can't build facilities wherever the need is. This reality in the field of sport and recreation adds to the pressure on the manager. of sport and recreation facilities. This pressure implicates that facility management involves far more than just the upkeeping of fields and buildings.
