Simulated Annealing : implementering mot integrerade analoga kretsar
Today electronics becomes more and more complex and to keep low costs and power consumption, both digital and analog parts are implemented on the same chip. The degree of automization for the digital parts have increased fast and is high, but for the analog parts this has not come through. This have created a big gap between the degrees of automization for the two parts and makes the analog parts the bottleneck in electronics develop. Research is ongoing at Electronics systems group at Linköping University target the increase of design automization for analog circuits. An optimizationbased approach for device sizing is developed and for this a good optimization method is needed which can find good solutions and meet the specification parameters.
Streamlining Streaming : Tilläggsfunktioner och dess betydelse för att designa en streamingtjänst
Streaming is a big field in todays digitalized society. The streaming market is huge, both in regards to the customer base, but also in regards to different providers and their stakes within this market. But how does the different providers go about in order to provide their users with added value? What does the user prioritize? The purpose of this study is to examine which additional functions can be considered important when designing a streaming service, which in turn will create an added value for the user. The study is based on a qualitative study of 6 individuals with semi-structured interviews and we will present an in-depth analysis regarding four fields of interest to us in regards to streaming services; second devices, recommendation systems, keywords and social connectivity.
Varför väljs nativeapplikationer istället för hybridapplikationer? : Prestandaskillnader hos hybridapplikationer
The development of applications for mobile devices has exploded in recent times. This has also led to the introduction of several new mobile operating systems. To streamline application development for multiple platforms, techniques have been developed to be able to reuse the same application regardless of the operating system. If the same application can be used on multiple platforms it will save both a lot of time and money. Today there are three types of techniques to develop an application; web, hybrid and native application, where the latter is specific to the operating system it has been developed to.
Kvinnors upplevelser av spiralinsättning samt faktorer som kan påverka insättningen
Syftet med denna studie har varit att granska den forskning som fanns beskriven i vetenskapliga artiklar omkring de problem som uppstår och de upplevelser som kvinnan får vid insättning av spiral. I en litteraturstudie valdes sju artiklar ut och deras vetenskaplighet studerades. Alla sju artiklarna var baserade på kvantitativa studier. Resultatet visade att smärta tillsammans med spiralinsättning var mycket vanligt. Den kategori av kvinnor som upplevde mest smärta var de kvinnor som inte hade fött barn på det naturliga sättet.
Projektdokumentation : Kritiska framgångsfaktorer
Projects of all kinds generate documentation that needs to be organized and stored for future use. Well adapted tools, together with a unified modus operandi need to be available for both the project members and those having a more organizing role if an organization is to be effective.A study of the tools available to project members at Svenska Kraftnät have been performed along with an analysis of the guidelines for the tools' usage. The study has focused on the needs of the project members, not the organization as a whole, thus providing a bottom-up approach to the problem instead of the more organizational top-down approach. Interviews of around 20 project members, whose roles include project leaders, technical experts and documentation supervisors, have been conducted to get an idea of the practical problems that exists.All systems, except for a local network storage device, were found to at least meet Svenska Kraftnät's current demands. The usage guidelines, however, covers only the general process that a project should follow and lacks detailed information on a per system level in several areas.
Tillagning i mikrovågsugn och dess effekt på livsmedel : En jämförelse med konventionell tillagning
Microwave is a time- efficient device for heating and reheating of foods. Despite the fact that its effects on foods have been evaluated during a long period of time, without any more negative effects shown compared to conventional cooking, one third of the Swedish population believes (in 2010) it accounts for a higher loss of nutrition.
This literature review aim to compile studies regarding how food is affected by cooking in microwave, with respect to cooking losses, nutrition, secondary metabolites as well as sensory and textural aspects and compare it with conventional cooking.
The compilation shows that different combination of effect (W), time and amount of water during microwave cooking have different effects on foods. The contents of proteins, vitamin B and carbohydrates are generally higher after microwave cooking, while anti-nutritional substances are affected much less during conventional cooking. This also depends on if it is of animal or non-animal origin. However, for the majority of nutrition values the differences are quite small.
Forensic Carving from Unallocated Space
Computer Forensics investigations have become more and more common while investigating IT-related issues. From experience, hard disks, USB thumb, memory sticks contains information that might be useful. Computer Forensics is regulary conducted by Police, Customs, Tax investigators but also within private companies and organisations. However, there are areas within the storage device that are not part of the organisied structure that a file system gives. The reason for that might be that the information has been erased by intention, a virus destroyed the file system and so on.

Mobilstudio för ShiShi TV
During the fall of 2007 Uppsala University gave the course ?Projekt DV?. As a result of this class a publishing tool for real-time media came to be ShiShi TV. The purpose of this application was to introduce a new way to reach out to people. This was done with a video player on the Internet and a second one placed in a regular mobile phone.
Undersökning & Utvinning av Smartphones : En djupgående analys av positionsdata
The ordinary phone of today is not the same as it was 10 years ago. We still use them tomake phone calls and to send text messages, but the ordinary phone of today has muchmore uses, it is essentially a computer. To put into context to 10 years ago, it is a verypowerful computer, capable of processing wide array of information and presenting it tothe user. Nearly every single device today has a wireless connection, which makes everyuser connectable and able to use online services and internet at any time and place.This gives the user the possibility to integrate his or hers everyday actions with socialmedia and different search functions. Being able to search the internet for persons,restaurants, public transportation and a lot more is very useful to most.
Bokslut? Den skönlitterära e-boken ur ett läsarperspektiv
The aim of this thesis is to accomplish a user study on how e-book users experience the electronic book, the e-book, as an instrument for reading fiction. The study is based upon qualitative interviews with twelve e-book users and a small survey carried out at the Stockholm City Library. The purpose is to identify the users' incentive for choosing the e-book as a medium for reading fiction, elucidate if and how the interface of the e-book affects the reading experience, and distinguish if there are any factors common to the users in their choice of reading e-books. How the users look upon the future of the e-book is also discussed. Among the people asked in the survey we note little if any demand for the e-book as an instrument for reading fiction.
Studenters inställning till fysisk aktivitet på recept - Ger yrkesutbildningen förutsättningar för studenterna att arbeta med metoden?
Det är vetenskapligt underbyggt att det finns ett tydligt samband mellan omfattning av fysisk aktivitet och hälsotillstånd. Genom att öka den fysiska aktiviteten går det att komma åt en av de stora grundorsakerna till vällevnadssjukdomar, fysisk inaktivitet. Fysisk aktivitet på recept (FaR) är en metod i ett steg mot en mer hälsofrämjande hälso- och sjukvård och för att etablera en långsiktig förändring av samhällets syn på fysisk aktivitet. Utvärderingar visar såhär långt att mer motivation och kunskap krävs hos vårdpersonalen för att arbeta efter FaR-metoden. Syftet är att undersöka attityden till FaR bland sista-termins studenter på läkar-, sjuksköterske-, sjukgymnast- och arbetsterapeut- utbildningen, samt om utbildningarna gett förutsättningar att kunna arbeta med metoden i framtiden.
Samtalsterapi på vårdcentral ? varför, hur och för vem?
Approximately one third of all patients in primary care have a psychosocial component to their illness that requires adequate professional treatment. However, primary care is insufficiently prepared for these patients. The aim of this case-study was to evaluate a pilot project in primary care offering psychotherapy as a treatment alternative. The data collected includes 1) data from 352 referred patients regarding demographics, diagnosis, treatment duration and pre- and post health status, 2) a patient-satisfaction questionnaire and 3) interviews with six therapists and five medical doctors. The treated patients improved significantly and showed a high degree of satisfaction.

Leder kastrering av hanhundar till bättre djurvälfärd?
Castration of dogs holds many reasons and opinions, therefore methods, traditions and rea-sons vary. The approaches have during time changed from mostly surgical castrations to also including hormonal treatments. Castration is used to control the dog's reproductive abilities, for medical reasons and to possibly rectify problems of behavioral nature. How common a particular method of castration is in a country is highly dependent on the country's traditions. In Sweden it is most common with castration for medical reasons, such as possible elimina-tion of diseases, for example, benign colorectal tumors.
