Inom vården utförs ofta schemaläggning av personal manuellt, vilket kräver mycket tid och resurser. Att planera arbetet för en grupp läkare, med dess ofta mycket komplexa sammansättning vad gäller exempelvis arbetsuppgifter och kompetenser, är ingen lätt uppgift. Detta examensarbete studerar huruvida en automatiserad taktisk bemanningsplanering med en tidshorisont på ett halvår till ett år, skulle kunna underlätta denna uppgift.I rapporten presenteras en måloptimeringsmodell som implementerats i AMPL för att med CPLEX som lösare generera förslag till bemanningsplaner. För att utveckla en matematisk modell som väl representerar de förutsättningar som råder vid bemanningsplanering av läkare har alternativa formuleringar provats och utvärderats. Den mest lovande av modellerna, som baseras på måloptimering, har i en pilotstudie testats på data från Onkologiska kliniken vid Linköpings universitetssjukhus.

The importance of chemical use is enormous for areas such as agriculture, industry and medicine and hence a prerequisite for our modern society. In order to protect humans and the environment from the negative effects of chemical use, chemical regulations have been used at a relatively early stage in our history. The purpose of REACH, the new chemical regulation of the European Union, is to generate new knowledge of chemicals within the European market and to increase the responsibilities of the enterprises when it comes to risk management. Whether the enterprises will implement the regulations or not will be of vital importance for the realization of the law?s intentions.The purpose of this study was to identify possibilities and problems that can occur when a downstream-user SME is about to implement REACH.

Målet med detta examensarbete var att utveckla en applikation på hemsidan www.gratisbio.se som kunde presentera medlemmarnas positioner på en karta. För att erhålla positioneringsdatan utnyttjades redan befintlig teknik som telefonoperatörerna tillhandahöll. Utvecklingsarbetet innefattade ett web-interface där relevant information kunde visas samt själva kartan som ritades upp med hjälp av Google Maps. Klientdelen av arbetet skrevs i html och JavaScript och serverdelen i PHP, utöver dessa användes format som XML, WSDL och JSON för att skicka information mellan klient och server. Den färdiga produkten utformades med Gratisbios allmänna utseende i åtanke. Applikationen använder samma färgschema och design vilket gör att den passar naturligt in på sidan. En utvärdering gjordes också för att se vilka ytterligare tjänster som skulle kunna tänkas vara intressanta för Gratisbio när det gäller positionering av mobiler.

Animation av karaktärer är en viktig del inom dataspel. Den interaktiva, oförutsägbara naturen av spel kräver att karaktärer måste kunna reagera dynamiskt på händelser i miljön för att upplevas som realistiska. För att göra detta möjligt räcker det inte att använda tekniker baserade på förinspelad animationsdata eller fysisk simulation av karaktärer i medvetslöst tillstånd.Ett system som kombinerar kontinuerlig fysisk simulation av karaktärer med ett kontrollsystem baserat på förinspelad animation åstadkommer fysiskt korrekta rörelser hos en karaktär. Genom att utöka ett sådant system med introducerandet av möjligheten för flera samtidigt samverkande kontrollsystem, baserade på dynamiska såväl som förinspelade tekniker, i ett uniformt interface kan en karaktärs rörelser modulariseras. Detta tillåter sammanställandet av en ?verktygslåda? av rörelser.En sådan uniform verktygslåda, kombinerad med en kontrollerande artificiell intelligens, gör det möjligt att utveckla fullt självständiga virtuella karaktärer i en dynamisk miljö..

This master thesis is a part of the DySCAS project at ENEA. The purpose of this thesisproject is to add support for streaming media and USB support to the DySCAS demonstratorplatform.To achieve this, some of the widely used middlewares available today were studied. The onethat proved to be of most interest is CORBA. Although CORBA?s solution to streamingmedia couldn?t be used due to their use of object programming, the CORBA solution didprovide some interesting thoughts regarding how the USB devices should be handled, in thiscase their ?resource inspector? and ?trading service?.Ethernet was the chosen network to support streaming media.

The use of vision applications are growing and the demand for integration and connectivity with other industrial automation control devices is increasing. Some businesses that are using vision technology follow US Food and Drugs Administration (FDA) regulation concerning audit trail. This thesis investigates the possibility to use vision technology for counting objects, achieving connectivity and to follow FDAs audit trail regulation. A market survey has been used to select suitable hardware and software to be used in the design of an application that is able to count objects and that uses standard industrial network connection i.e. OPC data access and Microsoft?s .NET components over Ethernet.

The students have been assigned a task from Consid, were they are supposed to develop a web based platform for handling the company?s consult CV:s. The key features of the system are to simplify the administration part at mission procurements towards customers and to match qualified consultants to certain missions.Consid is an international it-consult company and have about 1000 consults working for them. When Consid makes mission procurements towards a customer they have to manually match the best consult against a certain mission, this is both time consuming and complicated.The students started the project with big visions and thoughts about how the work would be performed and how the system would be developed. After the initial meetings and the closer it came to the beginning of programming it became clear that the expectations were too big.

An information system is something that evolves over time to enhance the company that is using it. The technology for building an information system is also evolving. New methods and new programming languages make system development easier. As new technology breaks ground and the demands of a company?s information system grow, the company will sooner or later get to a point where a change in the base of the system is necessary.

The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.

This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.

This thesis is a case study with a qualitative approach. The company examined is The Astonishing Tribe (TAT) making user interfaces for mobile phones. The company has had a growth of 1453% from 2002 until 2006. We have examined what are the key factors for keeping innovation while growing. The most significant factor not supporting innovation within the case company is the will to take calculated risks.

This is a report founded on a project by Atlas Copco called NYSTAB.  The application Nystab is a calculation program that can calculate the stability of the rockdrill-rigs made by Atlas Copco. The original version of Nystab is stored in a database from 1997 and the code is made in an old version of Visual Basic. My assignment was to develop the application in to a newer programming environment and make it last better in the upcoming years. The software I decided to use to accomplish this project is C# .NET in Visual Studio and Microsoft Access 2010. All the code is written in C# with some insertions from ADO.NET which helped me to easier connect the code with the database.The coding part was split into two pieces; the first was to develop the application scale done with Windows Forms, the second was to write the code for calculations in the application.

Network RTK is a real-time technique for accurate positioning with Global Navigation Satellite Systems (GNSS). The technology means the use of correction data from a network of GNSS receivers with known positions (reference stations) to reduce the uncertainty in position for the user´s GNSS receiver (rover). However, this requires that the correction data can be transferred seamlessly to the user in real time. Commonly the corrections are transferred via mobile phones. The Swedish National Land Survey operates a nationwide Network RTK service, where users can receive correction data via GSM or mobile Internet (GPRS).

In contemporary encryption the vast amount of text subject to cracking has brought about the demand for methods distinguish files more likely to be encrypted. The encryption software Truecrypt can encrypt files that are not possible to identify with a file signature. To solve the detection problem, an algorithm sensitive to the absence of structure in the very code of files was developed. The program was written in the programming language EnScript which is built into the forensic software suite EnCase. The essential part of the algorithm therefore deployes the statistic of a chi-square test for deviance from a uniform distribution to distinguish files with contents that appear to be random.
