Det problem som denna uppsats hade för avsikt att besvara var varför hemautomation inte används i fler hem. Genom resultaten från en enkät som distribuerades kunde slutsatsen att kostnaden för de befintliga lösningar som finns på marknaden idag inte låg i den prisklass våra respondenter ansåg rimlig. Författarna utvecklade då problemet och ställde sig frågan om en hemautomationslösning verkligen måste ha en så hög kostnad som de befintliga lösningarna har idag. För att belysa detta problem implementerades en egen kostnadseffektiv lösning där respondenternas mest önskvärda funktioner togs i beaktande och en testmiljö implementerades utefter dessa. Resultatet blev en hemautomationslösning med stor potential och med en betydligt lägre kostnad än dagens befintliga lösningar..

Hotell tillhör en bransch med svårigheten att skapa lojala kunder. Därför höjs kraven på hanteringen av mjuka värden, som kundtillfredsställelse. Genom att inkludera mjuka värden tillsammans med finansiella värden i en modell kan ledningen i hotellen balansera dem. Eftersom mjuka värden är starkt kopplade till personalens kompetens och motivation, är det svårt för en stor organisation som hotellkedjor att enbart lita till att företagsstrukturerna ska upprätthålla mjuka värden i organisationen. Den lokala ledningen har därför ett stort inflytande kring hur personalen och verksamheten närmast kunden hanterar mjuka värden.

Today?s society is one where technological advances are made daily, which increases the need to stop and assess the risks against users? integrity when integrating new technology in contemporary systems all the greater. We have taken two technologies, Near Field Communication and Certified Wireless USB, whose envisioned area of use is to be integrated into mobile phones, and evaluated what security threats are revealed for the respective technologies. The threats against security have been identified through research of the standards and existing reports for each technology. Practical experiments have not been conducted on account of us not having access to any equipment to run such trials.

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

I den här c-uppsatsen Are you smart enough to be stupid? är syftet att få ökad förståelse för hur Diesels - ett modeföretags - image framställs i dessa annonser. Vi besvarar frågor om vilket budskap annonserna förmedlar till dess mottagare och hur orden smart och stupid tolkas.

The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.

The background for this degree thesis is a need to replace the existing seal used to protect equipment containing secret or sensitive equipment used by Swedish Defence. The target design should satisfy both the need for tamper evidence and reduce Life Cycle Cost. In developing a new design for a seal, additional benefits such as improved logistics support and indication of attack methods such as heat and solvents have been considered.The lack of guiding principles for end users of seals became evident during the interviews. Major concerns for the future are education of users, information about actions if a seal is broken and user liability.The design work was divided into several phases. A feasibility study was performed including investigation of theory of labels, materials and possible technologies.

Context. In today?s society we use smart cards in many areas, NFC is a smart card technology that allows contactless interaction between a reader and the tag, the tag is often in the form of a card. NFC can be used for various payment methods or as access card to a building which makes life easier. In previous studies, the technique has proven to be weak to attacks using an NFC reader connected to a computer.

This essay is a study of the use of IT technology by teachers of English and History at a Swedish upper secondary school. It is based on four interviews and four observations. In my analysis of these I have made use of the theory of Social Shaping of technology, a theory which puts emphasis on a teacher´s purpose regarding the use of IT technology in order to empower the teaching process. As a researcher I aim to explore the reasoning on the part of the teacher and to that end I use the method of interviews and observations. This study shows different ways of using IT technology varying from one teacher to another.

Intelligent IT-based solutions, often called Smart Grids, are considered to be the future balancers of renewable energy sources. One area within the Smart Grid concept is called demand response, which is focused on making customers more consumption flexible by making them more active in their consumption. In this thesis the aim is to analyze a business model by investigating the income potential for a demand response solution as well as its market potential. This has been done through literature studies, interviews and development of a computational model.The use of 5000 households with flexible consumption can provide a cost reduction of 17.2% or 2.4 million SEK for a balance responsible party during an average year. If the solution is used to make strategic bids on the regulation markets the study indicates that the largest potential for revenues lies within this strategy.

This essay examines the role religion plays in kindergarten. Today, the Swedish kindergarten provides child care for a secular and multicultural society where religion is considered a private matter that should not influence government nor the policy documents of kindergarten and elementary school. According to a study by Jenny Berglund, there is a so-called Protestant bias present in the Swedish elementary school. Protestant bias is shaped by a ?marinade? of liberal Protestant Christianity and has an indirect influence on how other religions are described, how religion is defined and how concepts such as religion, tradition or culture are viwed.The study was also based on Ninian Smart?s dimensions of religion, whichcorrelates to Berglund?s theory on Protestant bias.
