Full textThis thesis is a reflection over a software engineering project, WAIS, and the work methodology that has been used within the project. Extreme Programming (XP) was the work methodology used during the process of development. We question if the choice of work methodology is suitable for this kind of project. The project was running by student during spring 2004 at Blekinge Institute of technology (BTH). The project WAIS was a part of a larger project named AIS 42 that runs with funds from VINNOVA. The main projects background and purpose are described in thesis so that the reader can understand the students’ part in the projects as a whole. The students’ main task was to develop a prototype for a system that disseminates information about logistics and transports. The system has many different end users and they come from various organizations that are spread out both physical and organizational. XP is treated as a methodology with in Agile manifesto, which principles are being explained in the thesis. Parallels are being drawn between the work process and the result from the work done. We reflect over the process and the work methodology from a perspective that has been brought forth from our years of education at BTH. The approach is built up upon theories from participatory design and human computer interaction where the user has an essential part of the process of development. The conclusion shows that the project has missed some of the advantages that XP brings. The reasons that we identified were; timeaspects, access to users and the lack of a joint objectiv.

Full textThe dissemination of personal computers has posed the designers the problem of developing more efficient interfaces that attend to the necessities of an ever growing diversity of users. At the same time, graphical user interfaces are complex systems of visual elements which meaning or function are not evident. Many approaches to these problems have been suggested, but little has been done towards the comprehension of graphical interfaces capacity to produce meaning. The goal of this work is to understand how Windows XP human interface produces meaning and conveys it to users. To do so, the signs of Windows XP interface where studied under the point of view of Peirce´s semiotics, in their relation to their inner properties, their objects and their interpretants, to the sort reasoning they arise, and to their power to create knowledge. Icons, menus and interface controls where selected as objects of analysis for their diversity and for the paper they play in the guidance of user interaction. This analysis was preceded by a detailed classification of Windows visual elements based on Microsoft´s publications concerning its interface design. A brief description of their characteristics and function was added to their classification. After the semiotic analysis an interaction test with Windows interface was accomplished with the help of some users, which were, afterwards, interviewed. This test consisted in the realization of nine tasks involving the interaction with Windows, which purpose was verify the hypothesis that the signs of the graphical interfaces analogous to that of Windows, for their strong symbolic character, rely much more on their interpretant to complete their semeiosis, and hence, they do not carry out effectively the task of producing and conveying enough information to users.

Full textOs métodos ágeis têm recebido grande atenção da comunidade de desenvolvimento de software nos últimos anos. Esses métodos propõem uma alternativa ao desenvolvimento de software dirigido por processos em prol de um desenvolvimento com foco nas necessidades dos clientes e das pessoas envolvidas, na entrega constante de software funcional, no desenvolvimento iterativo baseado em ciclos curtos de entrega e na aceitação da constante mudança dos requisitos ao longo do desenvolvimento. Por outro lado, os processos de usabilidade especificam práticas ao longo do ciclo de vida de desenvolvimento que contribuem para a qualidade da interface final no que se refere à usabilidade do produto. No entanto, os métodos ágeis não tratam das práticas relacionadas à usabilidade. Diante desse cenário, este trabalho propõe uma método denominado XPu. O XPu foi proposto como uma extensão do método XP e tem como principal objetivo tratar da usabilidade de produtos de software através de uma disciplina ágil. Resultados de uma inspeção e de um estudo de caso comparando o desenvolvimento de um produto utilizando o método XP e o método XPu sugerem um considerável ganho de qualidade na interface final a um custo de desenvolvimento relativamente baixo quando o XPu é utilizado

Full textSquamous cell carcinoma (SCC) is the most frequent metastatic skin cancer. His etiology is linked to exposure to ultraviolet radiation (UVR). Xeroderma pigmentosum C (XP-C) is a genetic disorder characterized by a severe susceptibility to aggressive SCCs following minimal exposure to UVR. XP-C cells are deficient in nucleotide excision repair (NER) of UV-induced DNA lesions. XP-C dermal fibroblasts expresse a phenotype resembling that of stromal fibroblasts associated to cancer cells with accumulation of reactive oxygen species and over expression of matrix metalloproteinase 1 (MMP1). We explored the effects of XP-C fibroblasts on migration and invasion of SCC cells. In organotypic skin cultures, XP-C fibroblasts promote the invasion of SCC cells. Also, scratch healing of SCC cells is enhanced with culture supernatants of XP-C fibroblasts through a mitogenic effect connected to increased ratio of SCC cells in the G2-M phase of the cell cycle. We show that XP-C fibroblasts overexpress the hepatocyte growth factor/scatter factor (HGF/SF) and activate the c-Met receptor and the p38 and JNK pathways in SCC cells. Blockage of HGF inhibits c-Met, p38 and JNK activation and prevented invasiveness of SCC cells within dermal equivalents. Spheroid assays show that XP-C fibroblasts lead SCC invasions. Our data indicate for the first time that XP-C fibroblasts are responsible for the formation of a permissive microenvironment towards SCC cells proliferation and invasion. Therapies targeting XP-C fibroblasts may be considered as a way to control aggressive cancer in XP-C patients

In this work, the technique Raman spectroscopy is used in order to study InxGa1-xP films grown with different thickness on GaAs (001). Two sets of samples grown by CBE (Chemical Beam Epitaxy) were analized: the first a GaAs buffer layer of 3000 Ǻ and the second with an 1800 Ǻ buffer layer. Concerning vibrational modes, it was possibleto conclude that for In concentrations around 50 % this alloy has a two mode behaviour. Polarized Raman spectra allowed to estimate the ordering degree of the samples. It was possible to observe strong disorder for all of then, with 0,l26 ≤ η ≤ 0,443. Photoluminescence measurements confirmed the disordering. The stress, the lattice parameters and the concentrationsin the alloys were obtained from the variations of the vibrational modes. The interdifusion of P atoms through the GaAs buffer layer previously observed by X-Ray measurements was confirmed. Finally, a comparative study showed that a sensible difference occur between the vibrational modes of the alloys belonging to each set (with different buffer layer thicknesses). Besides, the absorption coefficients, was also shown to be different for each set.
Neste trabalho a técnica de espectroscopia Raman é utilizada para o estudo de heteroestruturas semicondutoras finas com camadas de espessuras variáveis de InxGa1-xP de rede cristalina casada à do substrato GaAs (001). As amostras forma crescidas pela técnica de Epitaxia por Feixe Químico (CBE do inglês, Chemical Beam Epitaxy). Dois conjuntos diferentes foram analisados, sendo o primeiro com camada buffer de 3000 Å e o segundo com 1800 Å. A análise sobre os modos vibracionais desta liga permitiu concluir que para concentrações de Índio próximas a 50 % ocorre o comportamento denominado a dois modos . Realizamos medidas de Raman polarizado para estimarmos o grau de ordenamento de tais amostras. Pode-se observar uma forte desordem em todas as amostras analisadas, com 0,l26 ≤ η ≥ 0,443. Medidas de Fotoluminescência também foram realizadas confirmando o desordenamento. A partir da variação das freqüências dos modos vibracionais foi feita uma estimativa, através da análise das tensões, dos parâmetros de rede e das concentrações dos elementos que compõem a liga InxGa1-xP de rede casada à do GaAs. Nesta análise estudamos, ainda, a interdifusão de átomos de Fósforo na camada buffer formando a liga GaAs:P. Este fenômeno também foi observado anteriormente, por medidas de raios-X nas mesmas amostras. Por fim, um estudo comparativo levou-nos a concluir que existe uma sensível diferença entre os modos vibracionais das ligas de cada conjunto (com diferentes espessuras da camada buffer ). Além disso os coeficientes de absorção, estimados através da análise dos gráficos da razão das áreas sob a curva dos modos LO-GaAs e LO-GaP em função da espessura do filme, também apresentam-se diferentes para cada conjunto de amostras.

Full textRecentemente a comunidade de software vem se deparando com um grupo de novas metodologias de desenvolvimento de software, classificadas como metodologias ágeis . Algumas das metodologias que fazem parte deste grupo são Extreme Programming (XP) e SCRUM, sendo XP a mais conhecida e utilizada. Estas metodologias possuem em comum um conjunto de valores para o desenvolvimento de software, priorizando: indivíduos e iterações sobre processos e ferramentas; software funcionando sobre documentação compreensiva; colaboração do cliente sobre negociação de contrato; resposta à mudança sobre seguir um plano. Em paralelo à disseminação das metodologias ágeis, os investimentos em qualidade de software vêm aumentando a cada ano. Pesquisas realizadas sobre o setor de software, indicam um crescimento na adoção de modelos de qualidade como ISO 9000 e Capability Maturity Model for Software (CMM). Modelos de qualidade e metodologias ágeis possuem fundamentos opostos, como é possível notar nos valores definidos por essas metodologias. Autores de metodologias ágeis freqüentemente criticam modelos como o CMM. Em contra partida, alguns trabalhos indicam que é possível utilizar as duas abordagens em um mesmo ambiente. Este trabalho apresenta o Guia XP-CMM2, que tem como objetivo apoiar as organizações no uso da metodologia ágil XP em um ambiente nível 2 do CMM. Com o uso do Guia XP-CMM2, as organizações deverão se beneficiar da agilidade proposta por XP e da maturidade adquirida com o nível 2 do modelo de qualidade de software mais respeitado do mundo, o CMM. Para a elaboração do Guia XP-CMM2, foi realizado inicialmente um diagnóstico da satisfação de XP ao nível 2 do CMM e, depois, para cada problema identificado, uma solução foi proposta. Finalmente o Guia XP-CMM2 foi aplicado em dois ambientes distintos visando avaliação dos resultados obtidos

Full textFör att genomföra ett lyckat systemutvecklingsprojekt kan ett flertal utvecklingsmetoder användas. Utvecklingsmetoder hjälper till att undvika fallgropar under utvecklingsprocessen. De två typer av utvecklingsprocesser som arbetet baseras på är eXtreme Programming (XP) och Rational Unified Process (RUP).
Genom att identifiera skillnader samt hur XP och RUP kan kombineras, presenteras olika faktorer. En faktor är projektstorlek som enligt litteratur är den viktigaste faktorn vid valet mellan XP och RUP. Med hjälp av en enkätundersökning hos ett antal utvecklingsföretag har data samlats in för att ta reda på om projektstorlek är en huvudsaklig faktor för valet mellan XP och RUP. Undersökningen resulterar i att verifiera eller falsifiera om projektstorlek är en huvudsaklig faktor vid valet mellan XP och RUP. Undersökningen visar med hjälp av ett poängsystem att projektstorlek inte är den huvudsakliga faktorn, det vill säga att hypotesen om att projektstorlek är huvudsaklig, falsifieras

O presente trabalho busca fornecer, através de exemplos práticos e representações gráficas, uma estrutura capaz de orientar as organizações na escolha da metodologia mais apropriada para seus projetos de software. Um dos principais esforços dos pesquisadores envolvidos com a Engenharia de Software tem sido apresentar e abstrair modelos que descrevem processos de software. Estes modelos permitem que se compreenda o processo de desenvolvimento dentro de um paradigma conhecido. A existência de um modelo é apontada como um dos primeiros passos em direção ao gerenciamento e à melhoria do processo de software. Na última década, um novo segmento da comunidade de Engenharia de Software vem defendendo processos simplificados, também conhecidos como "processos ágeis", focados nas pessoas que compõem o processo e, principalmente, no programador. O trabalho apresenta a aplicação e avaliação de dois processos. O primeiro a ser discutido é o Extreme Programming (XP), o qual está entre os "processos ágeis" e que vai contra uma série de premissas adotadas por métodos mais tradicionais de desenvolvimento. O segundo processo é o ICONIX, o qual é definido como sendo um processo prático que utiliza a notação UML. Como produto final, além da aplicação de cada processo, são discutidos os seus pontos positivos e negativos. Um estudo comparativo entre os modelos é também elaborado, onde são examinados simultaneamente os recursos de ambos os processos, para desta forma, determinar quais características devem ser inerentes a um processo de software que garanta a produtividade e qualidade.

As metodologias ágeis vêm despertando interesse da academia e da indústria por apresentarem processos mais flexíveis. Estudos mostram o crescimento da adoção das metodologias ágeis Scrum e XP, no entanto, ainda há uma carência de evidências sobre como a utilização de tais abordagens influencia no desenvolvimento de software. Uma área que ainda apresenta lacunas de pesquisa é referente à satisfação dos stakeholders no projeto de software. Nesse contexto, o objetivo dessa dissertação é identificar o impacto das abordagens Scrum e XP na satisfação dos stakeholders em projetos de software. Para isso se faz necessário responder às seguintes questões de pesquisa: qual é o impacto do uso das metodologias ágeis Scrum e XP na satisfação dos stakeholders? Quais as evidências de contexto desses impactos? Com o objetivo de responder a estas perguntas, foi realizada uma revisão sistemática da literatura que encontrou 22 estudos primários relevantes, cujos dados foram extraídos e sintetizados em um modelo. Os resultados mostraram a identificação dos impactos das metodologias na satisfação dos stakeholders como: (1) aumento da responsabilidade e consciência do cliente; (2) melhora da gestão de risco e acompanhamento do projeto; (3) promoção da melhoria contínua e resolução de conflitos, entre outros.

Full textAgile Methods appeared at the end of the last decade as an alternative to traditional software development methods. They propose a new style of development, eliminating the cost of excessive and bureaucratic documentation, and emphasizing the interactions between people collaborating to achieve high productivity and deliver high-quality software. With an empirical process, based on constant inspect-and-adapt cycles, the team works towards an environment of continuous improvement. One of the practices proposed by Extreme Programming (XP) to enable the creation of such environment is called tracking. The role of a tracker is to collect metrics that support the team on understanding their current process. Finding effective ways to evaluate the team and the development process is not an easy task. Also, some of the possible problems are not always easily recognizable from quantitative data alone. This work investigates the use of metrics for tracking projects using Agile Methods for software development. A case study on the adoption of XP in seven academic and governmental projects was conducted to validate some of these metrics and to evaluate the level of adherence to the proposed practices, with the goal of assisting and supporting the tracker of an agile team.

Full textThe quality of software systems is a concern of every good project and much has been studied to improve the quality of the final product and process development. Software Testing is an increasing area, especially test automation, which is in evidence due to the speed and quality that it may bring to the development of software systems. Automated tests can be effective and can have a low cost of implementation and maintenance to ensure and control the quality of the systems. However, little knowledge about the area and common errors in writing and maintaining tests may bring additional difficulties to the software projects. Low quality automated tests do not contribute effectively to quality control systems and still take a long time of development. To avoid these problems, we present critically and systematically the core practices, standards and techniques to guide the process of creation, maintenance and management of automated test cases. Initially, comparisons are made between the test automation, other control practices, and quality assurance. Next, we present the most common problems and solutions for the automation of tests, such as issues related to specific types of algorithms, systems with data persistence, testing user interfaces and techniques for software development with automated tests. Finally, this essay reflects on the management and approach to test automation to make the process more productive and effective.

Full textExamensarbetet har sin ansats i utvecklingsmetoder närmare bestämt den lättrörliga utvecklingsmetoden Extreme Programming (XP). Beståndsdelen i en utvecklingsmetod är människorna, deras erfarenheter och kunnande samt deras förmåga att skapa idéer och lösa problem såväl enskilt som tillsammans. Utan nödvändig kompetens inom utvecklingsteamen ökar risken att utvecklingsprojekten misslyckas eller försenas. Syftet med detta arbete är att utifrån intervjuer med systemutvecklare undersöka vilka nödvändiga kompetenser som är nödvändiga för att XP skall kunna användas på ett effektivt sätt, även att uppmärksamma vilka problem som kan uppstå då den sociala kompetensen saknas. Metoden som har använts för att undersöka vilka faktorer som är nödvändiga i avseende till kompetenser är baserad på en kvalitativ ansats. Undersökningen har gjorts på två medelstora företag som använder XP vid utveckling av programvara. I stora drag har resultatet från denna undersökning utifrån intervjuer visat att social kompetens är viktig hos medarbetarna för att uppnå ett lyckat resultat. I ett projekt där samarbete med kunden sker kontinuerligt är det nödvändigt att systemutvecklarna har en god kommunikation vilken grundar sig på den sociala kompetensen. Slutsatser som kan dras från denna undersökning utifrån det empiriska materialet visar att social kompetens utgör en central roll inom XP. Systemutvecklare som använder XP behöver kunna kommunicera på ett klart och tydligt sätt, samt kunna samarbeta med övriga gruppmedlemmar för att projekten skall drivas framåt. I resultaten berörs även ytterligare kompetenser som kan vara till nytta vid användning av XP. Vidare redogörs för faktorer som kan vidtas för att uppnå kraven.

Severe stress results in global changes in the bacterial proteome. To respond effectively, new proteins must be synthesized, others destroyed. Coordinated changes in protein synthesis often result from the engagement of an alternate a subunit with the RNA core polymerase. The as subunit of the RNA polymerase is a master stress response regulator in E. coli. Under satisfactory growth conditions, proteolysis keeps the levels of as low; upon stress, various mechanisms converge to raise the levels as. In this work we focus on the facilitated delivery of as to the ClpXP protease. Proteolysis of as by ClpXP requires the accessory factor RssB. RssB is a two-component response regulator. Not surprisingly, its activity is positively regulated by phosphorylation of a conserved aspartate in its receiver domain. Whereas most response regulators are transcription factors, however, RssB is an adaptor protein. RssB binds to as, promoting a conformational change in as that exposes its N-terminal ClpX recognition motif. RssB also contacts ClpXP itself, enabling the formation of a quaternary degradative complex. Following the degradation of as, RssB is released. This work addresses two outstanding questions regarding RssB-mediated proteolysis of [sigma]s: 1) the requirement of RssB phosphorylation for [sigma]s degradation; and 2) the mechanism of RssB interaction with ClpXP. Previous studies have shown that phosphorylation of RssB increases its affinity for [sigma]s. Initially, phosphorylation of RssB was thought to be a pre-requisite for [sigma]s binding; more recently this has come under some debate. Our data demonstrate that phosphorylation is not strictly required for RssB function.
(cont.) Using both wild-type RssB and an unphosphorylatable variant, we show that the impact of phosphorylation on RssB activity is condition-dependent. With regards to the interaction between RssB and ClpXP, we demonstrate that critical contacts are made between the N-terminal domain of ClpX and a ClpX-binding sequence located, not at the C-terminus of RssB [sigma]s previously predicted, but within the inter-domain linker of RssB. This sequence motif is similar to those used by the other ClpXP adaptor proteins, all of which make contact with the ClpX N-domain. These results support a model in which adaptor proteins interact with a common binding site on ClpX. Indeed, we show that competition between SspB and RssB can occur in vivo and in vitro. We postulate that competition between adaptors is important in modulating substrate prioritization in times of stress.

Resumo: Apresentamos neste trabalho um estudo do crescimento epitaxial de InXGal-XP sobre GaAs que tem por objetivo a obtenção do ln0,49Ga0,51P. Em nosso trabalho, medimos a composição do InXGal-XP e a taxa de crescimento em função do fluxo de TMIn + H2 e a energia da banda proibida em função da composição. Este conjunto de medidas mostra um comportamento anômalo do material em tomo do casamento com o GaAs. Atribuímos este comportamento ao efeito do ordenamento da liga. Dentro da faixas estudadas, verificamos que a taxa de incorporação do Ga aumenta e que a taxa de incorporação do In diminui com o aumento da temperatura de crescimento e que a composição do InXGal-XP em função do fluxo de PH3 é praticamente constante. Realizamos também crescimentos epitaxiais de InXGaMl-XP sobre GaAs com dopagens intencionais de Silício (tipo N) e de Berílio (tipo P) em duas temperaturas de crescimento . Para as dopagens com o Sílicio, verificamos que a concentração de portadores é proporcional à pressão de vapor deste elemento e que não há uma diferença significativa na taxa de incorporação do Sílicio para as duas temperaturas de crescimento . Para as dopagens com o Berílio, verificamos que a concentração de portadores é proporcional à pressão de vapor deste elemento para valores menores que aproximadamente 3,0xl018 cm-3. Vimos que para menor temperatura de crescimento ocorre um aumento da concentração de portadores e a cristalinidade da camada de InxGal-xP:Be melhora. A análise destes resultados indica a formação de complexos de Berílio. Por fim, iniciamos um estudo das interfaces InGaP-GaAs. A análise preliminar dos resultados experimentais mostra que o aumento do fluxo de PH3 melhora a qualidade das interfaces
Abstract: We present here a study on the epitaxial growth of lnXGal-XP layers on GaAs aiming at the composition InO.49GaO.51P which is lattice matched to GaAs. In this work we evaluated the growth rate and composition of InXGal-xP as a function of TMIn+H2 f1ow, as well as the variation of band-gap energy with layer composition. This set of results pointed out an anomalous behavior of this temary material for compositions close to the lattice-matched oneswhich is attributed to an ordering effect in the alloy. For the temperature range studied here we observed increasing Ga and decreasing In incorporation rates with growth temperature. Also, the InXGal-xP composition does not depend on PH3 flow. We have cauied out intentiona1 doping of the InxGal-xP/GaAs layers for two different growth temperatures. The dopant sources used were Si (n type) and Be (p type). For the Si-doped material, the cauier concentration is proportional to the Si vapor pressure and there is no significant difference in the Si incorporation rate for the two growth temperatures. For the Be-doped material, the cauier concentration is proportional to the Be vapor pressure on1y for values lower than ~ 3xl018 cm-3. For lower growth temperatures we observe an increase in Be electrical activation as well as an improvement in the crystal quality ofthe InXGal-XP layer. These results indicate the formation of Be clusters at the higher temperatures used here. We have also studied the quality of the InGaP-GaAs interfaces. A preliminary analysis has shown an improvement of these interfaces as a result of increasing PH3 flows

Full textExtreme programming (XP) är en av flera lättrörliga utvecklingsmetoder. Detta innebär att arbetssättet är strukturerat på ett sätt som gör att systemets innehåll enkelt kan omformas efter uppkomna önskemål under projektets gång. Dessa metoder är alltså anpassade för att hantera förändrade kravbilder under pågående projekt. Principen är att framtiden är föränderlig, varför det behövs utveckling som stöder föränderlighet.
Kunden ges en betydelsefull roll i lättrörliga utvecklingsprojekt.
XP består av ett antal praxis (practices) som tillsammans syftar uttryckligen till att utveckla enastående (outstanding) programvara. Vi har dock funnit att XP inte kan sägas utgöra en metod i bemärkelsen som Goldkuhl (1992) definierar en metod.
Vår huvudsakliga fråga som besvaras i uppsatsen är hur XP kan användas. Vi har genomfört tvåfallstudier. Vi var nyfikna på att förstå hur företagen löser problematiken att XP inte har en väl beskriven arbetsföljd. Vårt syfte med denna uppsats har varit att genomföra en metodvärdering av XP för att visa hur XP kan användas och vilka styrkor och svagheter som finns i XP. Genom detta vill vi försöka ge råd tillföretag och organisationer som funderar på att införa XP som systemutvecklingsmetod. Analysarbetet har vi genomfört med hjälp av Multi-grounded theory. Metodvärderingen har vi gjort enligt MA/SIMM.
Vi har i vår undersökning bland annat kommit fram till att bägge företagen som vi undersökt lyckas få till fungerande metoder med hjälp av XP. Vidare har vi funnit att XP innehåller styrkor som gör att projektgruppen utvecklar system med rätt sorts funktionalitet och system med kodrelaterat få fel,samtidigt som kunden får snabb kundnytta och projektgruppenen kompetensspridning. Vi har också kommit fram till att XP innefattar svagheter som leder till att XP upplevs kaotiskt. Vi tycker bland annat att XP kräver att flertalet av projektdeltagarna är erfarna utvecklare.

Full textBehovet av tillgänglighet på kommunikation innebär att vi idag har krav på att meddelanden som skrivs över webben inte bara når oss via en dator utan även till våra mobiltelefoner. Målet med examensarbetet har varit att genom litteraturstudie och intervjuer konstruera ett webbaserat SMS-system som kan användas till att sända SMS textmeddelande till en godtycklig mobiltelefonenhet. Meddelande som sänds ska även lagras i databas och administreras via webbsidan. En jämförelse har även genomförts där syftet har varit att undersöka bäst lämpat programspråk för Bluetooth applikation. Metoden har grundat sig på kriterier. Jämförelsen mellan programspråken gav att Java med bibliotek från BlueCove var det bäst lämpade programspråket. För konstruktion av SMS-systemet har en objektbaserad utvecklingsmodell tillämpats, dock inte i full skala. SMS-systemet är konstruerat av webbsida, databas, blåtandsapplikation, Bluetooth- och mobiltelefonenhet. Webbsidan bygger på ASP.NET 2.0, databasen XML och blåtandsapplikation programmerades i Java. Kontroll har utförts att systemet uppfyller kravspecifikation.
As there is now wide access to the World Wide Web, demand now exists for Web messages to be available not only via a computer but also via cell phones. The aim of the project was, by means of literature studies and interviews, to create a web-based SMS-system which can be used to send SMS text messages to arbitrary mobile phone devices from a web page. The sent messages are also to be stored in a database and administered by means of the website. A comparison was also conducted in which the aim was to investigate the most suitable programming language for the Bluetooth application. The model for the study was based on given criteria. The comparison suggested that the Java programming language with its library from BlueCove was the most suitable. For the development of the system an object-based model has been applied, but this has not been adopted in a full scale manner at the present time. The SMS-system has been constructed by means of a Website, database, Bluetooth application and mobile phone unit. The website is based on an ASP.NET 2.0, database on XML and the Bluetooth application was written using Java. A control was conducted in order to test that the system meets the required specifications.
