Thesis (MTech (Information Technology))--Peninsula Technikon, 2004 / This dissertation was written in fulfillment of the requirements for the degree Master of Technology in the Faculty of Information Technology at the Peninsula Technikon in South Africa. The dissertation covers the introduction of the study; the reviews of the case, Free and Open Source Software; the discussion of methodology of software project management in terms of software engineering; the analysis of assessment methods; the techniques of using PHP, MySQL, Apache and CVS; and the implementation of a test module. The research represents the consideration of the problem, namely that there are few free assessment manager programmes that can be used for the quick and efficient deployment of academic assessments. An experimental research method was used to with the aim of solving the above problem. In other words, a test management system module had to be designed and implemented to function within the architectural constraints of a developing Open Source Software (OSS) Learning Management System (LMS), which is called Knowledge Environment for Web-based Learning Next Generation (KEWL.NextGen). The test management system is a module developed on Object-Oriented Programming (OOP) in PHP and MySQL application. The scripts of this test module are written under the KEWL.NextGen' application framework, which is based on a close approximation of model, view and controller (MVC) design III pattem. Now the entire source coding of the test module has been uploaded to Web site http://kngforge.uwc.ac.za. This test module can be used for the creation and management of an online test. It provides facilities to create a new test, and to preview, edit, delete and mark an existing test. Three question types have been achieved, namely multiple-choice, true/false and short answer.

Thesis (MTech (Information Technology))--Peninsula Technikon,Cape Town, 2004 / Higher education and online discussions are an integral part of collaboratively based e-Learning systems. However, there problems can be associated with current online discussion models. For example, it can be easy to set open-ended discussions which attract little participation and to assess contributions can be difficult or time-consuming. Students may not achieve the expected learning outcomes without proper structure and management in online discussions. This paper proposes to design and implement a discussion forum object to function within the architectural constraints of an existing Oss learning management system (to meet target user requirements) that is a web-based environment for online discussions where the facilitator can structure each discussion according to its nature and where learning requirements are using already designed templates.

Thesis (MTech (Information Technology))--Peninsula Technikon, Cape Town, 2004 / This document describes the design and implementation of an Assignment Management Module (AMM) to function within the architectural constraints of an eXisting open-source software (OSS) Leaming Management System (LMS). The project is established for Infonmation Technology Department Master Degree Project of the Peninsula Technikon. The Assignment Management Module will be constructed in orders to make it easier to create, mark, and manage assignments and record individual student perfonmances. The design entailed work on different function blocks like a user's authorisation, files uploadfdownload and mailing reminder unit as well as writing and testing of the application code on the intemet/intranet. The development process of the project to explore how to fu lfi11 software engineering methodology in an open-source environment, also presents details of the design architecture and technologies to be used, as well as being mindful of its future directions. The target audience of this document is anyone with an interest in an open-source software project in general, and in a Learning Management System in particular. If the reader has also been a contributor to Learning Management System, and especially to the management of assignments, this document may provide additional value, in that it strives to present a new approach to the understanding of such a module.

Foi desenvolvido um protótipo de hardware de sistema de monitoramento meteorológico como tecnologia aberta e livre e voltado para a ciência cidadã, chamado de Estações Meteorológicas Modulares (EMM). Foram considerados critérios de acessibilidade dos materiais e facilidade de modificação no desenvolvimento do projeto. Todos os programas utilizados no desenvolvimento são softwares livres. Um dos elementos desenvolvidos, a placa de controle das EMM, possibilita medir diferentes parâmetros meteorológicos, além de realizar o registro dados e envio para um servidor. Também possibilita a inclusão de novos sensores. Por todos esses fatores, é considerada satisfatória quanto a sua funcionalidade. A estrutura mecânica das EMM atingiu um patamar de preço acessível a indivíduos e organizações como escolas e associações de moradores de bairro, e apresenta fácil adaptabilidade a diferentes condições de instalação. O custo total do sistema ficou abaixo de alternativas proprietárias amadoras e significativamente abaixo de alternativas proprietárias profissionais. Soluções acessíveis para alguns elementos da EMM ainda requerem testes mais aprofundados. Parte das ferramentas utilizadas na fabricação da placa de controle ainda carece de maior disseminação junto à sociedade para acessibilizar o sistema das EMM. Os registros de desenvolvimento do trabalho foram feitos em forma de documentação aberta por meio de cadernos de laboratório abertos. As atividades de fabricação, montagem e instalação das EMM foram feitas seguindo métodos colaborativos chamados de Encontros de Fabricação Colaborativa e Mutirões das EMM. O resultado deste trabalho, unindo as documentações, os registros dos métodos colaborativos de fabricação, montagem e instalação e as consolidadas oficinas do projeto, é sintetizado no Guia da Comunidade EMM. Este é um roteiro para quem quiser fazer parte e ampliar uma rede de monitoramento ambiental colaborativo com as EMM, e é baseado em atividades educacionais para compreensão dos diferentes elementos da ferramenta e para a emancipação tecnológica. Uma das EMM foi comparada com uma estação automática oficial do Instituto Nacional de Meteorologia (INMET). Nessas comparações, as medidas de temperatura e pressão atmosférica apresentaram diferenças menores do que a acurácia dos sensores, enquanto a umidade relativa do ar apresentou uma diferença acima da acurácia do sensor. Este foi um primeiro passo de validação das EMM. / It was developed the hardware prototype of a meteorological monitoring system as free and open source hardware with focus on citizen science. The system is called Estações Meteorológicas Modulares (EMM, from Portuguese Modular Meteorological Stations). Affordability and reachability of materials and ease of remix were criteria considered in the development of this project. All the programs used in the development are free software. One of the elements developed, the control board of the EMM, is considered satisfactory in terms of: the parameters it enables to measure, the functionalities of communication and register of data, and the possibility of inclusion of new sensors.. The resulting solution to the mechanical structure of the EMM is low cost, affordable to schools and neighborhood associations, and is easy to adapt to different conditions of installation. The whole cost of the system is lower than proprietary amateur alternatives and significantly lower than proprietary professional solutions. Reachable and affordable solutions to some elements of the EMM still need some deeper testing. Some of the tools used to produce the control board still need a broader dissemination among the society in order to ensure the reachability and affordability of the EMM system. The work development registers were made as open documentation by means of open laboratory notebooks. The EMM fabrication, mounting and installations activities were made as collaborative methods called Encontros de Fabricação Colaborativa (from Portuguese, Collaborative Fabrication Gatherings) and Mutirões of the EMM. The result of this work, merging the documentation, the register of collaborative methods of fabrication, mounting and installations, and the consolidated workshops of the EMM project, are synthesized in the EMM Community Guide. This is a script to the ones who want to make part and expand the collaborative environmental monitoring network with the EMM, and it is based in educational activities to comprehend the different elements of the tool and to promote the technological emancipations. One of the EMM was compared to an official automatic meteorological station from Instituto Nacional de Meteorologia (INMET, from Portuguese Meteorology National Institute). In this comparison, the temperature and atmospheric pressure measurements showed differences lower than the accuracy of the sensors used, and the relative air humidity presented a difference higher than the accuracy of the sensor. This was the first step to validate the EMM.

The goal of this Diploma thesis is to create suitable materials that could be used by teachers teaching the program GIMP at elementary schools. GIMP graphic editor is an open source program released under the GPL licence and is used for raster graphics tool. Its quality is comparable to many other similar top graphic editors that, contrary to GIMP, are not for free.

Visando reduzir estes custos e diminuir as incertezas características de uma fase em que se tem pouca informação, esta pesquisa propõe o uso de Open Source GIS, também conhecidos como Sistemas de Informações Geográfica de Código Aberto, combinado com a aquisição de dados geoespaciais gratuitos de fontes públicas e oficiais, para posterior processamento e refinamento de informações. Para a composição deste trabalho foi realizada aquisição de dados públicos disponíveis sobre a região dos corpos Pegmatitos da Fazenda Primavera, localizada na Província Pegmatítica da Borborema, no município de Tenório, Paraíba. Os dados foram utilizados para a produção e refinamento de informações como a delimitação e localização dos corpos, realização de estudos geomorfológicos, logísticos e estimação de volumes. Os processamentos das imagens e dados, além da confecção de mapas, e análises tridimensionais dos afloramentos foram executados em um único programa, o software livre Quantum GIS. Os produtos gerados permitiram concluir que é possível extrair e produzir informação de elevada qualidade a partir de dados disponíveis de forma gratuita, utilizando softwares oficiais, reduzindo os custos iniciais de um projeto de mineração, podendo continuar a ser utilizados nas fases posteriores, caso o empreendimento mineral se prove viável. / The initial phase of a mining project requires a strong investment with a very uncertain feedback because it is necessary the data acquisition to locate, define and estimate the volumes of mineral reserves of interest. In order to reduce these costs and reduce the characteristic uncertainties of a stage where there is little information, this research proposes the use of Open Source GIS (Geographic Information Systems), combined with the acquisition of free geospatial data from public and official sources for further processing and refinement of information. For the composition of this research it has been carried out the acquisition of public available information about the region of pegmatites bodies at the “Fazenda Primavera”, located at the Borborema Pegmatitic Province, Tenório county, Paraíba. The data have been used for the production and processing of information as the delimitation and location of pegmatites, realization of geomorphological and logistic studies, and estimation of volumes. The processing of the images and data besides maps making and threedimensional analyzing of outcrops were executed in a single program, the free Quantum GIS software. The created products allowed the conclusion that it is possible to extract and produce high-quality information from free available data, using official software, reducing the initial costs of a mining project, which may continue to be used in later phases if the mineral project proves to be feasible.

O manejo populacional de cães e gatos é um conjunto de estratégias para controlar e prevenir problemas relacionados com o convívio entre esses animais e os seres humanos. Nesta tese é proposto um fluxo de trabalho baseado em métodos quantitativos, para auxiliar o planejamento, implementação e monitoramento de programas de manejo populacional de animais de companhia. Ao seguir o fluxo de trabalho é possível coletar dados para caracterizar populações, analisar esses dados para propor intervenções e avaliar o efeito das intervenções. A proposta foi baseada na articulação de cinco pesquisas. Na primeira pesquisa foi implementado de um desenho amostral complexo para caracterizar a população de cães e gatos domiciliados de Votorantim, São Paulo. Na segunda pesquisa que foi baseada nos dados levantados na primeira, foram usadas análises de correspondências múltiplas para identificar perfis de opiniões públicas em relação ao abandono de cães e gatos. Na terceira pesquisa foi avaliada a validade do desenho amostral usado na primeira pesquisa, mediante simulações estocásticas. Na quarta pesquisa foi desenvolvido um modelo matemático de manejo populacional que permite priorizar as intervenções de acordo com o efeito que produzem. Na quinta pesquisa foi desenvolvido um modelo matemático para avaliar a eficiência do controle reprodutivo realizado com contraceptivos de efeito reversível. Os modelos das duas últimas pesquisas foram baseados em sistemas acoplados de equações diferenciais e em análises de sensibilidade global e local. A proposta foi implementada em um software de código aberto, o pacote do R capm, que pode ser incorporado na rotina de trabalho dos setores envolvidos no manejo populacional de animais de companhia / Dog and cat population management is a set of strategies to control and prevent problems related with the coexistence between those animals and human beings. In this thesis it is proposed a work-fiow based on quantitative methods to support the planning, implementation and mo- nitoring of companion animal population management programs. Following the work-fiow, it is possible to collecf data to characterize populations, analyze that data to propose interventions and assess the effect of interventions. The proposal was based on the articulation of five rese- arches. In the first research, a complex sampling design was implemented to characterize the owned dog and cat populations of Votorantim, São Paulo. In the second research, which was based on data from the first one, public opinion profiles regarding dog and cat abandonment were identified using multiple correspondence analysis. In the third research, the validity of the sampling design used in the first research was assessed through stochastic simulations. In the fourth research, a mathematical model of population management was developed. With that model, it is possible to prioritize interventions according to the effect they produce. In the fifth research, a mathematical model was developed to assess the efficiency of reproductive control based on contraceptives with reversible effect. The models of the last two researches were based on systems of coupled differential equations, and on global and local sensitivity analysis. The proposal was implemented in an open source software, the R package capm, that can be incorporated in the working routine of sectors involved with companion animal population management

Este trabalho se inicia com uma discussão sobre as principais características dos Sistemas de Arquivos Distribuídos, ou seja, espaço de nomes, localização, cache, consistência, replicação, disponibilidade, escalabilidade, heterogeneidade, tolerância a falhas e segurança. Analisamos diversos sistemas de arquivos existentes quanto a estas características dando especial atenção aos sistemas NFS, Andrew, Coda, Sprite, Zebra, Harp, Frolic e Echo. Descrevemos alguns modelos analíticos para o comportamento de sistemas de arquivos distribuídos e, em seguida, apresentamos um novo modelo para sistemas baseados em leases - um mecanismo para a garantia de consistência em sistemas distribuídos. Finalmente, descrevemos a nossa implementação do sistema de arquivos distribuído SODA - que utiliza leases - apresentando dados sobre o seu desempenho. / We begin with a discussion of some of the main characteristics of Distributed File Systems, namely locality, name space, cache, consistency, replication, availability, scalability, heterogeneity, fault tolerance and security. We analyze several file systems based on these characteristics. We focus mainly on NFS, Andrew, Coda, Sprite, Zebra, Harp, Frolic, and Echo. We then describe some analytical models of the behavior of distributed file systems. After that we present a new model of systems based on leases - a mechanism to assure consistency on a distributed system. Finally we describe our implementation of the SODA distributed file system - which uses leases - presenting some results on its performance.

Antalet programvaror ökar för varje dag och människor använder dagligen en mängd olika sorters programvara både på datorer och på andra enheter. Det finns idag programvara som kallas för fri och öppen programvara som tar upp kampen med gamla klassiska proprietära programvaror. Öppna och fria programvaror släpper sin källkod helt fri så användaren själv har möjlighet att göra ändringar i den programvara som används medan proprietär programvaras källkod är skyddad och hemlig. Dessa tre olika sorters programvaror jämförs och diskuteras utifrån tekniska likheter och skillnader i denna kandidatuppsats.   Syftet med denna kandidatuppsats inom informatik är att undersöka vad privatpersoner som är tekniskt intresserade har för tankar och attityder kring proprietär, öppen och fri programvara och visa vilka tekniska aspekter som prioriteras vid val mellan dem.   I undersökningen har ett kvantitativt angreppssätt bestående av en webbenkät som besvarats av privatpersoner tillämpats. Resultatet från denna enkät har tillsammans med den teori som insamlats visat vilka tekniska funktioner och skillnader som påverkar en privatperson då val av olika sorters programvara ska ske.   Undersökningen har visat att det som användaren prioriterar högst i en programvara är användbarheten som handlar om hur användarvänligt användargränssnittet är och hur lättanvänd en programvara är. Vidare har undersökningen visat att de proprietära programvarorna är överlägsna när det gäller användarvänlighet.   Trots den förmodan som finns om att proprietära programvaror är mycket mer säkra och tillförlitliga än fria och öppna alternativ så har undersökningen även visat att fria och öppna programvaror ofta är lika säkra och tillförlitliga. Ibland överträffar de till och med de proprietära programvarorna i både säkerhet och tillförlitlighet.   Vidare visar undersökningen att fria och öppna programvaror till störst del inriktar sig till utvecklare. Detta för att om användaren ska kunna dra någon nytta av att källkoden finns tillgänglig och möjligheten att själv ändra och anpassa programvaran efter eget tycke så krävs kunskaper inom programmering som en väldigt stor majoritet av alla datoranvändare i världen inte innehar.     Nyckelord: proprietär programvara, öppen programvara, fri programvara, proprietary software, open source, free software.

In an era of technological growth, cloud computing is one of the hottest topics on the market. This, along with the overall increased use of digital systems, requires solid integration options to be developed. Redpill Linpro recognizes this and has developed a cloud-based Integration Platform as a Service (IPaaS) solution called Connectivity Engine. New techniques like this can however seem very abstract to a customer, something which a demo application could help substantiate. To aid in this issue we have developed a web-based Enterprise Resource Planning (ERP) system as well as an Integration Application to connect the ERP system with Salesforce.com in a bidirectional integration. With the use of Connectivity Engine this can be hosted in the cloud and be easily accessible. The project has been a success for Redpill Linpro as well as the authors. A solid way to demonstrate the abilities of Connectivity Engine has been developed along with descriptive documentation for any sales representative assigned to pitch the platform.
