Therefore it is important that software is measured in order to improve the quality. The question is not whether we should measure software but how it should be measured. Software measurement has been in existence for over three decades and it is still in the process of becoming a mature science. The many influences of new software development technologies have led to a diverse growth in software measurement technologies which have resulted in various definitions and validation techniques. An important aspect of software measurement is the measurement of the design, which nowadays often means the measurement of object oriented design. Chidamer and Kemerer (1994) designed a metric suite for object oriented design, which has provided a new foundation for metrics and acts as a starting point for further development of the software measurement science. This study documents theoretical object oriented cohesion metrics and calculates those metrics for classes extracted from a sample of open source software packages. For each open source software package, the following data is recorded: software size, age, domain, number of developers, number of bugs, support requests, feature requests, etc. The study then tests by means of association rules which theoretical cohesion metrics are validated hypothesis: that older software is more cohesive than younger software, bigger packages is less cohesive than smaller packages, and the smaller the software program the more maintainable it is. This study attempts to validate existing theoretical object oriented cohesion metrics by mining open source software data with association rules.

Magister Scientiae - MSc (Bioinformatics) / Biobanks are collections of biological samples and associated data for future use. The day to day activities in a biobank laboratory is underpinned by a laboratory information management system (LIMS). For example, the LIMS manages the execution of tests on biospecimens and track their movement and processing through the laboratory. There are a range of commercially available Biobank LIMS systems on the market but their costs are prohibitive in a resource limited setting. The cost of Commercial off-the-shelf software includes the initial cost of acquiring the system, as well as the cost of maintenance and support throughout the software's life cycle. The Bika LIMS system on the other hand is Free and open source software (FOSS) with decreased license cost, used routinely in non-medical laboratories. Ideally, if Bika LIMS could be customised to handle human biospecimens, then both biobanks and genetics laboratories could benefit. Central to any biobank functionality in Bika LIMS is the ability to import information from routine biomedical equipment. We identified two instruments that are key to human biobanking and are lacking in Bika LIMS namely BioDrop ?LITE and the Qubit Fluorometric instrument. Import interfaces for importing DNA/RNA concentration analyses from these instruments and management of the results with associated sample information would add value to the LIMS. The aim of the thesis was to customise Bika LIMS for utility in a biomedical laboratory. In collaboration with colleagues at Tygerberg medical school, the Bika LIMS software was customised to accommodate the DNA and RNA concentration analyses results for a pathology laboratory and the LIMS workflows customised for use at Tygerberg medical school. In this process the manual operations of Tygerberg medical school laboratory would migrate to the use of Bika LIMS. The analytical module in Bika LIMS was implemented using PYTHON, by using logic that allows importing of specific analyses. A template was created for the BioDrop ?LITE and Qubit Fluorometric instruments used for developing the interface for an analysis import form. The instruments generate results in CSV file format. A parser was created to read and parse the files uploaded from the import form, by splitting them into parts, extracting the data, and populating key-value pairs. The controller manages the submission of the form by initialising the parser that imports the specific file into the LIMS where it is managed by the configured Bika LIMS workflow.

Scrutiny of the capabilities and accuracy of computer forensic tools is increasing as the number of incidents relying on digital evidence and the weight of that evidence increase. This thesis describes the capabilities of the leading proprietary and open source digital forensic tools. The capabilities of the tools were tested separately on digital media that had been formatted using Windows and Linux. Experiments were carried out with the intention of establishing whether the capabilities of open source computer forensics are similar to those of proprietary computer forensic tools, and whether these tools could complement one another. The tools were tested with regards to their capabilities to make and analyse digital forensic images in a forensically sound manner. The tests were carried out on each media type after deleting data from the media, and then repeated after formatting the media. The results of the experiments performed demonstrate that both proprietary and open source computer forensic tools have superior capabilities in different scenarios, and that the toolsets can be used to validate and complement one another. The implication of these findings is that investigators have an affordable means of validating their findings and are able to more effectively investigate digital media.

Tesis para optar al grado de Ingeniero Comercial, Mención Economía / De acuerdo a la teoría del crecimiento económico, el cambio tecnológico es de una relevancia primordial para el desarrollo económico de los países. Es así como se aplican muchas políticas para fomentar la innovación con el objetivo de contribuir al crecimiento. Una de ellas son las leyes de propiedad intelectual, las que permiten a los innovadores internacionalizar los beneficios de sus invenciones; de esta forma incentivan la generación de contenido que de otra manera se perder a dada su naturaleza de bien público. Sin embargo, a su vez, la información es un elemento fundamental en el proceso de innovación; actúa como elemento detonante y facilitador del proceso de creación intelectual, por lo que la restricción del acceso a la información ocasionada por las leyes de propiedad intelectual es contraproducente para el desarrollo de nuevas ideas productivas. En este trabajo desmenuzamos el proceso de innovación y revisamos distintas formas que existen para conservar los incentivos sin la necesidad de restringir el acceso a la informaci ón pública como lo hacen las leyes de propiedad intelectual. Indicamos que un país como Chile puede beneficiarse de leyes de propiedad mas laxas que fomenten el uso de la información en los esfuerzos de innovación. Ejemplificamos con el fenómeno del Software Open Source, que instituciones mas permisivas junto con un uso fructífero de las nuevas tecnologías de comunicación de redes pueden resultar en esfuerzos colaborativos de innovación que disminuyan los costos tanto en términos monetarios como en términos de incertidumbre.

Em um campo que sofre constantes transformações, muitos profissionais da informática e correlatos ainda têm dificuldade em distinguir entre o 'programa gratuito' e 'programa livre'. Este documento transpõe para o universo da Comunicação em Multimeios uma pesquisa com objetivos teóricos e práticos acerca dos benefícios da tecnologia de 'código aberto' para o setor de Multimeios. Como objeto de estudo, foi desenvolvido um sistema Web com a tríade PHP, MySQL e Apache para o Arquivo Sonoro Neotropical, fundado em 1977 e atualmente dirigido pelo Prof. Jacques Vielliard. Tudo se inicia com uma fundamentação teórica que expõe definições e polêmicas, bem como justifica a escolha das linguagens acima mencionadas, que têm sido o centro das atenções nos últimos tempos. Órgãos internacionais utilizam essas ferramentas para a inclusão digital e o avanço das pesquisas científicas, em reação aos altos preços impostos pelo mercado proprietário. Será observado como é possível a autosustentabilidade dentro da proposta do livre e gratuito. Intenciona-se apontar qual o espaço reservado ao setor de multimeios dentro deste cenário e quais os benefícios para pesquisadores e profissionais da comunicação em audiovisual. Este trabalho pretende demonstrar que essas linguagens e tecnologias são confiáveis e podem auxiliar o profissional de comunicação em multimeios no gerenciamento de arquivos de multimídia / Abstract: People are watching a war between software free movement and proprietary industry. In a place with constant changes there are a lot of people, professionals from this area or not, that just can't understand important nuance between 'open source' and 'software free'. This document transport to the Multimeios Communication language important concepts about software free and open source movement. We'll to know important discoveries to that area knowledge. The web system called Arquivo Sonoro Neotropical is our study object, and He was building with PHP, MySQL e Apache technologies. He was founded in 1977 and still under the same administration, the scientist Jacques Vielliard. In the beginning the reader will understand definitions, polemics thoughts and a justification about digital inclusion and for the selected languages and technologies. On the other hand, we going to know what the proprietary industry does to still on the dispute. We going to appoint some solutions that free technologies has to Multimeios, specially with audio edition. There is an intention to demonstrate that free movement has a real possibility to help the Multimeios Professional to management digital files in the web / Mestrado / Mestre em Multimeios

Vi, två studerande vid Karlstads universitet, har efter önskemål från IBM intervjuat tre representanter från utvalda svenska tillverkningsföretag om hur de ställer sig till Linux på klientsidan och sedan jämfört detta med vad IT-analysföretag anser om Linux och en övergång till detta på klientsidan. Vi har även utfört en djupintervju med en anställd på IBM för att ta del av deras syn och åsikter om varför de valt att satsa på Linux på klientsidan och vägt in detta i våra intervjuer med tillverkningsföretagen. Vi frågar oss, är det någon skillnad i uppfattning mellan hur olika IT-analysföretag ser och skriver om Linux och hur markanden ser på Linux och vad de egentligen tycker? Att Linux kommer gå en ljus framtid till möte är samtliga involverade parter i vår uppsats eniga om. Trots detta skiljer sig deras åsikter om vilket operativsystem som är det mest kostnadseffektiva, IT-analysföretagen säger Linux, tillverkningsföretagen säger Microsoft. En ökad konkurrens på marknaden ser samtliga som positivt men poängterar att det måste finnas ett verkligt skäl till en övergång då det kostar mycket pengar och att det är så pass mycket att tänka på.

Context/Background: The adoption of Open Source Software involves more than using OSS products and this has marked a new trend in software development. This new practice has potential benefits while introducing peculiar practical challenges in software development; particularly in areas concerning OSS selection. This involves OSS search and establishment of selection criteria which selects the best OSS product that matches the system requirements. These challenges have also introduced significant bottlenecks into software development industry. In order to mitigate or solve these problems, there isa need to identify OSS success factors for any software development firm that wants to go OPEN. Objective: This thesis aims to investigate the benefits and limitations of adopting OSS and to identify the success factors that lead to the benefits of OSS in software development. Method: Systematic literature review, through searches in library databases, was used to review empirical studies on OSS success factors when going OPEN. The data was extracted and synthesized from the selected papers for analysis. Mapping was used to obtain information concerning the OSS success factors when going OPEN, benefits, limitations/bottlenecks encountered in the industry, and were used to validate our findings from the literature. Results: Ninety three papers were identified. The data extraction from the SLR helped to identify the success factors, benefits and the bottlenecks from the literatures in the past decade. Conclusion: The implications of our thesis are two fold; practitioners should be acquainted with the benefits and limitations of adopting OSS and also learn from our identified success factors that leads to benefits in software development. This will help them when going OPEN. Alternatively, researchers should align their work and try to identify more knowledge gaps using our identified bottlenecks/limitations for software organizations when going OPEN. / Context/Background: The adoption of Open Source Software involves more than using OSS products and this has marked a new trend in software development.
