This project was conducted with the view of extending the Durban Municipal Open Space System into surrounding municipalities. It was aimed at adopting a holistic approach to nature conservation by providing for the needs of the current human population whilst ensuring the long term survival of representative natural biota of the area. A preliminary study was conducted to: provide a basis for a more detailed vegetation survey; to assess the current public open space areas and to determine the land use history of the area. The vegetation was categorised into 14 community types and mapped to provide the basis for more detailed sampling. A survey of public open spaces revealed that most of the public parks were not providing for the needs of the local residents and that nature reserves and sports fields were more popular than conventional public parks. The land use history study revealed that the study area has been utilised for: cultivation; grazing; market gardening and more recently residential and industrial development purposes. A vegetation survey using phytosociological methods revealed that the vegetation in Queensburgh was dominated by alien invasive plant species although pockets of indigenous vegetation did occur. Drawing from the principles of reticular biogeography an open space system was designed using the information gained from the vegetation survey and preliminary study. The design included: 4 core areas where conservation was a priority; 3 corridors linking the core areas and a number of buffer areas. A general management plan was subsequently developed for the system. Management suggestions were concerned with: ecological; economical and sociological aspects. The open space system offers Queensburgh the opportunity to contribute to the national reconstruction and development program (RDP) by upgrading the current standard of living of the local residents without compromising the natural resources available to future generations. / Thesis (M.Sc.)-University of Natal, 1994.

Este trabalho busca demonstrar a importância do Sistema de Espaços Livres na estruturação do ambiente urbano, tendo como recorte espacial um bairro consolidado da cidade de Maceió. Destacam-se os conflitos e potenciais encontrados no Sistema de Espaços Livres Públicos (SELP) desta cidade e, de um modo mais específico, da área selecionada para análise: o bairro Benedito Bentes. Esta análise compreende também uma leitura das formas de apropriação dos espaços livres públicos, especialmente as ruas, e estudos sobre a frequência de uso de determinados espaços - em particular os campos de futebol criados pelos próprios moradores em áreas ainda não ocupadas por edificações, que revelam a necessidade de implantação de espaços destinados ao lazer e à recreação para suprir a demanda existente, constatada por meio deste estudo. / This work focuses in the importance of the Open Space System in the structuring of the urban environment, based on a consolidated neighborhood of Maceió city. Detach the conflicts and potential found on Public Open Space System of this city and, specifically, selected area for analysis: the Benedito Bentes neighborhood. This analysis also comprises an observation about appropriation forms Public Open Space, especially the streets, and studies of use frequency of certain spaces - in particular, the football fields created by the dwellers in areas not occupied by buildings, which show the need of deployment of spaces for leisure and recreation to cater existing demand, evidenced by this study.

Dans un contexte où les tensions liées aux ressources énergétiques fossiles sont de plus en plus vives, concevoir une nouvelle manière d'appréhender le contexte énergétique est devenu essentiel. Les moyens de production et de consommation énergétiques habituels ont montré leur limite avec l'apparition de nouveau type de pollution pour différents secteurs. Dans ce rapport de thèse, nous nous sommes essentiellement axés sur le secteur de l'électricité en proposant un outil, d'aide à la décision, pour simuler la consommation électrique ainsi que la production électrique à partir des énergies renouvelables (EnR). La simulation de la consommation électrique permet d'avoir des informations à différents échelles d'observation en s'appuyant sur une démarche systémique et typologique, qui permet de calculer le bilan carbone associé à cette consommation ainsi que son coût annuel. Par la suite, cette consommation a été analysée à l'échelle horaire afin de pouvoir là mettre en relation avec des fichiers de production pour effectuer un pilotage au niveau de la courbe de charge. Ce pilotage a pour but de lisser les pics au niveau de la courbe de charge. Les premiers résultats analytiques obtenus à l'aide des outils développés montrent qu'il est possible de réduire l'appel au réseau électrique normal à un certain niveau en fonction des dimensionnements des systèmes de production EnR et du stockage. Ainsi que de pouvoir limité les coûts d'investissement au juste nécessaire, c'est-à-dire avoir un prix le moins cher possible, grâce à une optimisation du système EnR. / In a context where the tensions linked to fossil energy resources are increasing, design a new way of understanding the energy context has become essential. The usual means of energy production and consumption have shown their limit with the appearance of new types of pollution for different sectors. In this thesis, we mainly focused on the electricity sector by proposing a tool to simulate electricity consumption and electricity production from renewable energies (RES). Simulation of electricity consumption allows having information on different observation scales based on a systemic and typological approach, according to which the associated carbon footprint to this consumption is being calculated as well as its annual cost. Subsequently, this consumption was analyzed at the hourly scale, which is to relate it to the production files in order to control the load curve. This control aims to smooth down the peaks of the load curve. The first analytical results, obtained by using the developed tools, show that it is possible to reduce the use of the normal electrical network to a certain level according to the dimensions of the RES production systems and storage.

From its infancy, environmental psychology [which concerns itself with the coinfluencing interface between people and places] has required attention to actual context, and attention to social relevance. There has always been an emphasis on research into real problems within a context of meaningful theory, and on results which have potential not only for individuals, but also for policy-makers and those who execute that policy. This environmental psychology study is about the potential role of green open space in contributing towards quality of life in the city generally. It is also about a specific, wellloved urban open space in Namibia's capital city, Windhoek, the Avis dam environment, which is often the contentious target of proposed commercial development. At the moment, the Windhoek Municipality has no well-structured urban open space policy, and possibly also no full understanding of the meanings of the Avis dam for its users. This study hopes to make contributions to both these areas of policy-making. As the applicability of research findings to the development of public policies and community interventions depends very much on the suitability of the methodology and theories chosen (Stokols, 19911), this study begins with a discussion of systemic and ecosystemic thinking [Chapter Two]. They were chosen as the guiding metatheory for this study, not only because of their recognition of the inescapable connectedness between person and environment, but because of their personal appeal too. Chapter Three examines theories and models which are compatible with systems thinking, and which help understand the potentially positive psycho-social and socio-economic roles of urban open space generally, and how the extent of that potential in a specific open space may be appreciated and described. The implications of systemic/ecosystemic metatheory for the study's methodology and research design are discussed in Chapter Four, and the data collection methods, which comprised observation and interviewing, in Chapter Five. Ecosystemic thinkers do not believe that facts can be "found" [they are not there objectively, but co-emerge subjectively from people's individual and collective experience in a place], so Chapter Six deals with a co-emergent interpretation of the data gathered. Based on that interpretation, recommendations for urban open space policy generally, and the Avis dam environment specifically, are made in Chapter Seven. AFRIKAANS : Omgewingssielkunde (wat gemoeid is met die mede-beinvloedings tussen mense en plekke) het van sy vroegste jeug aandag benodig ten opsigte van werklike verband asook maatskaplike toepaslikheid. Daar was nog altyd klem op navorsing ten opsigte van daadwerklike probleme binne die verband van ‘n betekenisvolle teorie asook op die uitslae wat potensiaal het vir die individualis sowel as die beleidsbepalers en beleidsuitvoerders. Hierdie omgewingssielkundestudie gaan oor hoe groen oop spasies moontlik kan bydra tot kwaliteit van lewensgehalte in die stad oor die algemeen. Dit gaan ook oor ‘n besondere, geliefde stedelike oop ruimte in Namibia se hoofstad, Windhoek, nl. die Avisdamomgewing, wat voortdurend ‘n teiken is vir bedryfsontwikkeling. Tans beskik die Munisipaliteit van Windhoek nie oor ‘n welsaamgestelde beleid oor oop ruimtes nie en moontlik ontbreek ook by hulle die nodige begrip van die betekenis van die dam vir sy verbruikers. Hierdie studie be-oog om ‘n bydrae in die beleidsbepalings van altwee leemtes te lewer. Die toepaslikheid van navorsingsbevindings in die ontwikkeling van openbare beleid en gemeenskapsbemiddeling hang baie van die gepastheid van die metodologie en teorië (Stokols, 1991)2 af. Hierdie studie begin met ‘n bespreking oor sistemiese en ekosistemiese denke (Hoofstuk Twee). Hulle is as die leidende metateorieë gekies, nie alleen vir hul erkenning van die onontkombare verband tussen persone en hul omgewing nie, maar ook vir hulle persoonlike aantrekkingskrag. In Hoofstuk Drie word teorië en voorbeelde bestudeer wat verenigbaar is met sistemiese denke en wat help om die potensiële positiewe psigo-sosiale en sosio-ekonomiese rolle van stedelike oop ruimtes oor die algemeen te verstaan, asook hoe om die omvang van die potensiaal van ‘n spesifieke oop ruimte te kan waardeer en te kan beskryf. In Hoofstuk Vier word die implikasies van die sistemiese/eko-sistemiese metateorie vir hierdie studie se metodologie en navorsingsplan bespreek. Die dataversamelingsmetodes wat uit waarneming en onderhoude bestaan, word in Hoofstuk Vyf hanteer. Ekosistemiese denkers glo nie dat feite “gevind” word nie (dit is nie objektiewelik daar nie maar ontstaan subjektiewelik deur persone se individuele en gesamentlike ondervindinge van ‘n plek), dus word die vertolking van die saamgestelde data in Hoofstuk Ses bespreek. In die lig van dié vertolking word aanbevelings 2 Stokols, D. (1991). Conceptual strategies of environmental psychology. In D. Stokols& I.

The purpose of this thesis is to consider the rigth way how to make a user space extension of RedirFS, which works as a Linux kernel module and implement it. There is described a model of user and kernel spaces used in Linux and how this two spaces can communicate with each other. There are several communication mechanisms described with a description of use. Bandwidth and latency tests for all these mechanisms are implemented. Measurement results are presented and the suitable mechanism is chosen. The second part of the thesis is focused on redirctl and urfs. The first solution represents the RedirFS control tool, the second is the implementation of user space filters.

The diploma thesis deals with the use of a simulation model for the development of an automatic algorithm for the creation of a routing table and route evaluation in a transport system. It includes a search of modeling and simulation issues and state-space search issues with an analysis of available search methods. The simulation model of the transport system is created in the software Tecnomatix Plant Simulation, where an algorithm for automatic creation of routing tables for routing and evaluation of routes according to static criteria is subsequently developed and tested. The work presents a proposal for the principle of the algorithm for evaluating the routes of the transport system, including dynamic criteria and their optimization.

The aim of this thesis is to analyse and interpret the existent and future needs of the people and environment of the mission station, Kwasizabantu,to ensure settlement growth that will enhance the social, economical and environmental aspects of the settlement. This will result in a development framework of the whole site, a master plan for the lifespan of the settlement and detailed design of the heart of the settlement. / Dissertation (ML(Prof))--University of Pretoria, 2009. / Architecture / unrestricted
