<p>Utveckling av olika typer av påbyggnadskod till programvaror blir allt vanligare. Dessa som går under samlingsnamnet plugins skiljer sig från vanliga applikationer då de har en annan struktur samt speciella beroenden till applikationsspecifika moduler. Problem uppstår när denna typ av utveckling inte stöds av de vanliga utvecklingsmiljöer som finns ute på företagen och delar som borde vara automatiserade måste utföras manuellt. Syftet med studien är att undersöka hur utvecklingsmiljön för Java på Sandvik IT Services kan anpassas för att stödja plugin-utveckling för IBM Lotus Notes. I denna studie undersöks skillnaden mellan plugin-utveckling och den vanliga Java-utvecklingen på företaget samt hur detta påverkar verktygen i utvecklingsmiljön. Resultatet beskriver hur utvecklingsmiljön kan anpassas för att stödja plugin-utveckling och en lösning för detta föreslås. Slutligen visas en implementation av lösningen i form av en prototyp där utvecklingsmiljön anpassas för plugins med Maven pluginet Tycho.</p>

<p>The PhonePages of Sweden is a company that develops software for mobile units, especially cell phones. This thesis treats the development of, and contingencies for, a mobile phone directory, using the limited resources found in a mobile unit. The project was implemented and executed at The PhonePages with the intention of creating a product to sell to a third party.</p><p>By studying different solutions, their benefits and drawbacks, an abstract picture of the product was constructed. Problems covered include compatibility problems caused by todays platform diversity as well as problems with saving, organizing and presenting data.</p><p>The main goal was to create a phone directory which does not make external information retrievals. The service should contain both company and personal information, with name and phonenumber. Complete address information should also be available. The application should also manage different priorities and logotypes for the company information. The application, that emerged as a result of our work at The PhonePages, works independently, without making connections to the Internet and is completely implemented in J2ME, all according to the requirement specification. In other words, the analysis of the different solutions led to a working application.</p>

<p>Datormobiler (<em>smartphones) </em>har blivit ett populärt fenomen bland mobilanvändare. Det har dykt upp ett flertal stora aktörer på marknaden och i takt med att fler <em>smartphones</em> har utvecklats har också intresset för applikationsutveckling blivit större. En av dessa aktörer är Apple som idag har en betydande marknadsandel efter lanseringen av iPhone. Dock har Google tillsammans med <em>Open Handset Alliance</em> blivit en betydande konkurrent med deras mobila plattform Android.</p><p>Syftet med denna uppsats är att göra en jämförande studie av applikationsutveckling för dessa plattformar. I detta ingår att undersöka plattformarnas programmeringsspråk med tillhörande aspekter, utvecklingsmiljöer, krav på utvecklaren och de ekonomiska aspekter som hör till utveckling och publicering. Denna studie genomförde vi genom att undersöka tillgänglig och aktuell litteratur och försäljningsstatistik. Vi använde även egna erfarenheter i applikations-utveckling på plattformen Android.</p><p>Vår undersökning visar att utveckling för iPhone är endast möjligt via företagets egna produkter. Detta är inte fallet med Android då det är mer valfritt vilken plattform man vill utveckla på. Båda programmeringsspråken är objektorienterade men har några märkbara skillnader. Båda plattformarna erbjuder en pedagogisk och lätthanterlig utvecklingsmiljö där man som utvecklare snabbt kan se resultat. Det är gratis att införskaffa nödvändiga programvaror och som utvecklare får man behålla större delen av intäkterna om man väljer att publicera sin applikation med ett pris i någon av applikationsbutikerna.</p><p>Vår slutsats är att plattformarna har fler likheter än olikheter när det gäller applikations-utveckling. En av skillnaderna är att utveckling på iPhone innebär att lära sig ett programmeringsspråk som används nästan exklusivt på Apples produkter och eventuellt betala en årlig avgift. I Androids fall används ett välspritt programmeringsspråk och enda kostnaden är en relativt liten engångssumma för publicering. I sin helhet kan man tolka skillnaden som att utveckling för iPhone innebär en stängd tillvaro, men fri från skadlig kod medan utveckling för Android är mer öppen som får till följd att den är mer osäker.</p>

<p>In 2002 an amendment was added to the International Convention for the Safety of Life at Sea (SOLAS) which opened up for shipbuilders to replace steel with lightweight materials in the superstructures. However, SOLAS requires equal fire safety compared to ships with steel superstructures.</p><p> </p><p>LASS-c is a cross-organizational project with the aim to find a method to build cruise ships with part of the superstructure made in lightweight materials. As a part of the LASS-c project the purpose of this thesis has been to develop an application in Java (FISPAT). The tool has been designed to find fire sensitive areas in structures such as cruise vessels. A second aim with the thesis has been to evaluate the cruise ship Norwegian Gem with respect to fire sensitive areas.   </p><p> </p><p>In FISPAT the user can make a model of a structure. The model is built up by rooms, networks and devices. With the model, FISPAT can simulate fire spread and the effects on the networks included in the model. The user can then analyze the results to find fire sensitive parts.</p><p> </p><p>One of the main results in this thesis is the tool itself together with this report which also serves as a manual to FISPAT. An evaluation of Norwegian Gem was also made which points to some critical parts of the ship. One example is the main water supply pipe to the sprinklers which has no redundant systems and all sectioning valves are manually operated, hence it is vulnerable to faults. The electrical feed to the three pump units is also a vulnerable point on the vessel. The pumps have redundant electrical networks, but the wires are drawn on the same paths, making it possible to take out both systems with one fire.</p>

The primary objective of this research is to develop a network-centric simulation modeling framework that can be used to build simulation models through the use of Internet-based resources. An object-oriented programming approach was used to build a Java-based modeling framework focused on modeling a semiconductor fabrication system. This research is an initial step in what may be a new network-centric simulation modeling methodology, where simulation models are created using software objects that are physically located in many different sites across the Internet. Once the ability to create and run a relatively simple model using a network-centric approach has been established, future research may lead to a simulation environment that not only lets a user interactively build models but also allows concurrent model development between a group of users, independent of their location, operating system, or computer architecture. The prototype system implemented as a portion of this research is performed in the Java object-oriented programming language. A target system model is presented as an example of how the environment can be used to apply the network-centric simulation modeling methodology. / Graduation date: 1998

In the age where quick turn around time and high speed manufacturing methods are becoming more important, quality assurance is a consistent bottleneck in production. With the development of cheap and fast computer hardware, it has become viable to use machine vision for the collection of data points from a machined part. The generation of these large sample points have necessitated a need for a comprehensive algorithm that will be able to provide accurate results while being computationally efficient. Current established methods are least-squares (LSQ) and non-linear programming (NLP). The LSQ method is often deemed too inaccurate and is prone to providing bad results, while the NLP method is computationally taxing. A novel method of using support vector regression (SVR) to solve the NP-hard problem of cylindricity of machined parts is proposed. This method was evaluated against LSQ and NLP in both accuracy and CPU processing time. An open-source, user-modifiable programming package was developed to test the model. Analysis of test results show the novel SVR algorithm to be a viable alternative in exploring different methods of cylindricity in real-world manufacturing.

P2P Grid computing seeks the convergence of Grid and P2P technologies. Deploying a P2P Grid middleware on a set of computers enables an organization to automatically barter computing time with other Internet-connected organizations. Such P2P exchanges of computing time enable individual Peers, i.e. organizations, to transparently aggregate large amounts of computational power with minimal infrastructure requirements or administrative cost. Challenges arise from the requirement for scalability and robustness. Individual worker nodes are unreliable, as P2P Grids operate on unmanaged desktop computers. A specificity of P2P Grids is that each Peer can reclaim at any time the computational power of worker nodes supplied to other Peers, leading to bursts of execution preemption. These are the major contributions of our dissertation: * Firstly, we propose a new P2P Grid architecture, the Lightweight Bartering Grid (LBG). Through systematic cooperation between Grid nodes, the reliability of execution of computational requests is greater than the sum of the reliabilities of worker nodes. * Secondly, we propose a highly scalable data transfer architecture. It is based both on the BitTorrent P2P file sharing protocol and on the removal of the temporal cost of downloading redundant copies of input data files. * Thirdly, besides a middleware implementation of LBG, we also provide an implementation of a discrete-event simulator. Its originality resides in the weaving of the simulator code into the bartering code of the middleware, which is made possible through the virtualization of Grid nodes. This enables reproducible testing and accurate performance evaluation of the bartering policies because the Peers of a simulated Grid make the same bartering decisions as Peers deployed on real computers. The LBG architecture exhibits the following remarkable features: * The scheduling model supports the queueing of external requests and the architecture enables a flexible study of bartering policies. * The architecture is open, flexible, lightweight and facilitates software engineering. It enables the easy development, testing, evaluation and deployment of combinations of scheduling policies. * The architecture is fully P2P.
