Development and accuracy tests of advanced exchange trading systems require well adjusted tools for testing. Aptness of these tools are probable to have a major impact on identification of bugs and verification of new functionality. Identifying erroneous parts and bottlenecks of the trading system is of outmost importance for the exchange as a whole since stability and correctness are two of the determinant factors its viability is measured by. This paper covers how this test-tool was created and the motivation behind the design choices made. The tool was created with the goal to be broad enough to cover the majority of cases that could arise, fast enough to be able to test the trading systems speed limitations (i.e.

Physical activity can reduce the risk of developing dementia, and studies show that people who already have some form of the disease can get a better memory function and find it easier to perform daily tasks if the activity is performed regularly. People who are diagnosed with dementia are generally not offered physical activity to a high extent, nor is there a wide range of equipment developed to suit the target group.The Bike Around project was launched during a workshop in Copenhagen and was organized by HCH and Techna Science with the aim to develop new training equipment for people with dementia. The workshop resulted in the development of a customized training bike where the user can get a biking experience from his wheelchair or favorite chair. By integrating the pedal movement with a prerecorded movie projected on a screen, the memory can be stimulated both visually and by the activity itself.Our assignment in the project consisted of three parts: design of the bike, movie playback and software programming. During the project a prototype has been created that meets the requirements of ergonomics and usability..

Denna rapport dokumenterar arbetet med att utreda hur C# och Pitch RTI fungerar tillsammans, och vilka prestandaeffekter som resulterar av denna koppling. Motiveringen kommer från att kunder till företaget Pitch har efterfrågat stöd för C# som programmeringsspråk när de använder Pitch RTI. Metoden gick ut på att successivt lära sig använda de tekniker som finns tillgängliga, för att sedan implementera lösningar på hur kopplingen ska ske. Resultaten visar hur övergången går till och prestandan som uppnåddes med hjälp av indexnotation. Tekniken IKVM hade högre prestandaindex och gick snabbare att komma igång med jämfört med tekniken C++/CLI.

A vehicle that carries a person sitting in a wheelchair has been rebuilt. The original vehicle was provided with a petrol engine, hydrostatic drive and a mechanical steering rod, making it noisy and hard to maneuver. The purpose with this project was to convert the vehicle to make it more environmental and easier to drive.A new design has been proposed where an electrical drive has replaced the noisy combustion engine and an electrical motor with joystick control has replaced the manual steering.The project was divided into two parts. One mechanical part where the construction of the drive and steering were to be decided. The other part involved programming the microprocessor and implementation of all the necessary electrical for the control system of the vehicle.

Enligt oss så är det största problemet med att processuellt generera en pseudo-oändlig spelvärld i realtid är att få genereringen att ske så sömlöst som möjligt samtidigt som världen upplevs som konsekvent. För att finna lösningar på detta problem så analyserar vi andra studier och spel som utnyttjar processuell generering. Vi använder sedan de metoder och tekniker vi funnit för skapandet av en egen applikation för att få en djupare förståelse för hur dessa fungerar i praktiken och hur mycket varje metod påverkar prestandan. I vår slutsats beskriver vi de problem vi fann, deras orsak och ger förslag på lösningar. På grund av studiens tekniska karaktär så riktar den sig främst till programmerare.

The Swedish Armed Force has a need to streamline the preparation of an exercise in tactical training for soldiers because the preparation of an exercise is currently laborious and time consuming when commanders manually share files to each computer that will be included in the exercise. The degree project was to create a file sharing program within the internal network of the Defence Forces? international centre (Swedint). The program is used by the training management to effectively start up an exercise where soldiers train tactical training in a simulated combat environment. The training management use this program to upload files to a server which notifies all the computers on the network to download these files.

Automationscenter & Bråvalla Elteknik AB is a company that offers the market completed total solutions where the customer can operate and monitor their production from the terminal. In these total solutions they lack standard circuit which are developed by the company and which could manoeuvre/control/monitor controlled process objects. This report defines the work of developing the most common standard circuits.The report is initiated by a short theoretical part about PLC and the PLC system, with a connected terminal, which has been used. Thereafter, the turnout of the demands of specification is reported, after discussing with the supervisor in the course of the project. The report concludes with a disclosure of how the programming, the documentation and the testing have proceeded and a final discussion concerning the project and proposals on continuation.The result is a CD with the documentation of standard circuits and how they are implemented in a new project.

This report intends to analyze the difference between the original rules and a modification of the rules for the Scandinavian version of the world famous dice game yatzy (yahtzee). Several works are made previously existing strategies for yatzy and Yahtzee.The study was conducted using the optimal strategy calculated and implemented in the programming language Java. The execution of the application to create the file containing the optimal strategy was running on leased powerful servers from Amazon and took just over six hours each.A simulated player played 100,000 games based on the strategy, to obtain data which then was used to plot graphs and analyze the expected score and its standard deviation. The expected value (mean) and standard deviation of the score for the possibility of three or four throws were 233.00 ± 44.82 and 280.07 ± 41.25.In view of the results drawn the expected conclusion that the four possible throws provides increased probability of getting a high score, unlike the case where the player may only be able to throw the dice three times. The fact that the variance is lower in the case of four throw session is equivalent to that the likelihood to get close to the expected value increases..

We are working on the development and design of an approach to agents that can reason, react to the environment and are able to update their own knowledge as a result of new incoming information. In the resulting framework, rational, reactive agents can dynamically change their own knowledge bases as well as their own goals. An agent can make observations, learn new facts and new rules from the environment, and then update its knowledge accordingly. The knowledge base of an agent and its updating mechanism has been implemented in Logic Programming. The agent?s framework is implemented in Java.

Det finns flera fördelar med robotiserad bågsvetsning jämfört med manuell bågsvetsning. När det gäller produktivitet och repeterbarhet är robot överlägsen människa, vilket gör att produkterna håller jämnare kvalitet. I slutet av 80-talet började offline-programmering att tillämpas. Att programmera en robot offline innebär att utföra programmeringen med dator utan direkt tillgång till roboten. Genom simulering visualiseras ett robotprogram i en grafisk modell av den fysiska robotcellen utan att den fysiska roboten behöver tas ur produktion.

In order to understand user behaviour and navigation patterns, user logging is today widely used in analysis and development of user interfaces. These user logs tend to be quite many and can contain a lot of different data. A big issue is how to process and display this data in a perspicuous way to the stakeholder. This study is about how to develop a prototype to handle this issue. It was solved by various methods from human-computer interaction.

Att skriva enhetstester är en viktig del i nya populära systemutvecklingsmetoder som extreme programming. Med testdriven utveckling skriver man testerna innan den källkod som skall testas. Ett vanligt problem med dessa tester är att de blir beroende av delar i systemet som inte är intressant för själva testen. Mock objekt är en teknik som gör det enkelt att isolera tester från allt som inte är relaterat till det som skall testas.Det finns två sätt att se på mock objekt. Den traditionella synen är att mock objekt skall användas som ett verktyg vid isolering av externa system.

The development of IT systems is usually accomplished by some form of system development methodology. It can be performed as the waterfall method, where each phase is completed before the next begins. One of the reasons to follow a development methodology is that the process is more structured, faster and that the product will have higher quality. One risk of not using a system development approach is that the code can be unstructured and difficult to maintain.This paper describes an alternative method in which the development occurred without the use of any system development methodology. This has been possible because there was a clear goal of the program that should be developed.

Fluids are important to the Visual Effects Industry but extremely hard to control and simulate because of the complexity of the governing equations. Fluid solvers can be divided into two categories, those of the Eulerian point of reference and those of the Lagrangian. Both categories have different advantages and weaknesses and hybrid methods are popular. This thesis examines Smoothed Particle Hydrodynamics, a Lagrangian method for physically based uid simulations. To allow the artist the exibility given by shorter simulation times and increased number of iterations, the performance of the solver is key.
