The amount of web APIs that are open to the public is increasing fast. Both the free web APIs as well as the ones that cost money to access. Both bigger and smaller organizations, professional and non-professional developers use these web APIs to add value to their systems or use it to create new applications. This is an area study where alot of research has been done in the last few years. In spite of this there are still no user-centered evaluation methods for web APIs.

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 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.

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.

Det huvudsakliga syftet med denna rapport är att genomföra och testa en implementationsteknik för ragdolls ämnade användas i spelsammanhang. Implementationen sker genom en kombination av en verletimplementering tillsammans med en fördefinierad bone-hierarki i meshen som skall användas. Verletimplementeringen programmerades som en grund till en enklare fysikmotor och parsningen och struktureringen av meshen sköttes parallellt utanför fysikmotorn. Rotationsmatriser för samtliga större kroppsdelar, såsom över- och underarmar, överkropp, huvud etc. beräknas sedan i fysikmotorn och används för att vrida mesh-kroppen rätt.

Forest enterprises have always searched for ways to improve efficiency. For the past few years there has been an emphasis on stock-keeping levels. Increased demand for fresh round timber and the need to decrease the amount of tied-up capital has made the forest industry reduce its inventory levels. This has brought on a higher demand on the timber supply from the forest management districts concerning both delivery in time and assortment output. As a result, the flow of timber has fluctuated a lot with serious consequence for the timber supply during 1994.

People live longer. There is a growing need to increase the knowledge of aging and of the need among the elderly for medical care in the near future. As a step towards meeting this need, a survey among the elderly in Skåne is made by the division of Geriatric Medicine in Malmö University Hospital. This survey is called Gott åldrande i Skåne, GÅS. A frequent decease among the elderly is Mild Cognitive Impairment (MCI).

Denna rapport aterger arbetsprocessen kring att utvärdera geograskatjänster, och att utveckla karttillämpningar för nätverk av rikstäckande omfattning. Arbetet utfördes pa plats hos DGC, en datakommunikations-, tele- och nätoperatör som distribuerar kundförbindelser i hela Sverige där konsumenter ansluts till stamnätet. Uppgiften bestod av att utvärdera möjligheter till att slå upp koordinater för etablerade kundplatser, rita ut accessnätet i ett kartgränssnitt och ta fram ett eller flera stödverktyg för bland annat orderprocesser. Användningsfall utifrån önskemål, arkitekturmönster samt analys av yttre leverantörers tjänster för geocoding avgjorde hur det slutgiltiga systemet var utformat. Mjukvaran som utvecklades integrerades både i bentliga system och som ensamstående tillämpningar.

Abstract During object-oriented system development, programming should be preceded by analysis and design to assure that the system fulfils the demands of the customer and simplify during the development phase and documentation. When modeling the analysis and design phases, several different notations may be used. One of these is the UML (Unified Modeling Language) which this thesis will cover. The aim is to compare the use of the UML i practice versus what is said in the literature. The investigation is built upon interviews at different companies to receive their reflections about the UML.

This Bachelor thesis is a qualitative study of the public debate regarding the role of Public service in the media converged society today. The purpose of this thesis is to examine how the public debate, that is the Swedish Public service television and people with broad representative knowledge about Public service, motivates a change of the function of the Swedish Public service television.Our issues are: What does the public debate say about the function of Swedish Public  service television in our society today and how is a change motivated in this debate? How does the public debate look upon today´s media convergence and the fragmentation of the audience which, according to Denis McQuail, is a consequence of this?The method of this thesis is a qualitative analysis and we have analyzed ten opinion articles and Swedish Public service television magazine ?DittSvt?. The theoretical background was obtained from Henry Jenkins and Håkan Hvitfelts theories and thoughts about mediaconvergence. We have supplemented this with Denis McQuails theory regarding the fragmentation of the audience.In this thesis, we see that the public debate is a lot about diversity in Swedish Public service television programming and that the democratic base is still very important.

The purpose of this essay is to analytically review and discuss architecturalcompetitions, mainly through the general views of a few selected workinglandscape architects, architects and scientists. I have studied the moral and workethicalaspects of using graphical presentations as a mean to draw attention,rather than trying to meet the set program points.My results are derived from e-mail interviews, literature studies and studies ofthe competition entry Stockholmssfären from the competition Stockholmsportenwhich was held in Sweden early 2011.The literature studies have shown that the available literature on architecturalcompetitions and research on the subject is biased towards architecture ratherthan landscape architecture. Worth mentioning is also that there is not a lot ofavailable literature, mainly due to lacking research on the subject.The informants for the interviews were selected based upon their academicmerits and/or experience of working with or doing scientific research onarchitectural competitions. The landscape architects? opinions regardingarchitectural competitions turned out to be in many ways alike ? they seemed tohave a pretty relaxed view of competing in architecture.

A study was carried in conjunction with the Orthodontic department at Halmstad General Hospital in Sweden to investigate the possibility of reducing cost and manufacture time of dental implant drill guides. The current system involves sending a digital image in STL format to the Materialise factory in Belgium where information of the position of dental implants is translated onto a moulded mouthpiece. Drill guides are placed in the mouth piece which is then returned to the surgeon. The mouthpiece complete with drill guides is then placed in the patients mouth and used as a guide for the implant drill holes. The cost of 10000 sek and a turnaround time of 2 weeks gave rise to the need for a faster and cheaper solution.

The earmould acoustics affect the amplification that the hearing aid is programmed to give to its user. It is therefore important that the choices made for the earmould are correctly done. One choice is regarding the shape of the soundbore that affects the frequency response of the hearing aid above a certain cut-off frequency. The purpose of this project was to measure the frequency response when altering the shape of the soundbore in the earmould. Additionally, the aim was to examine how the frequency response is affected when the shape of the soundbore is not set or is not possible to set in the software when programming the hearing aid.

The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.
