Implementation av FlexRay prototypstack
FlexRay is a new communication protocol which is fast, reliable and flexible and therefore can meet the increasing demands on data communication in the vehicle industry. The protocol is developed by an industrial consortium containing among others BMW, Daimler Chrysler, Motorola and Phillips. Today (May 2009) Hägglunds is using CAN for data transmission in their systems. CAN is getting obsolete and has difficulties in coping with the increasing flow of communication. In this report FlexRay and its communication capacity is studied.
Pilotutvärdering av KomHIT:
The study aimed to evaluate picture communication during clinical as-sessment and intervention procedures in paediatric care. As part of the project KomHIT (Augmentative communication in paediatric health care settings) care professionals at different care units were provided with education and designed pictorial supports. These consisted of appointment letters with pictorial support, visual schedules and communication boards with both general and specific vocabulary. Care professionals and parents to children with and without communication disabilities participated. Survey data from care professionals and parents at five care units was supplemented with qualitative data from an interview with a multiprofessional group at one of the care units.
Bör regeln om anvisad leverantör revideras eller rent av avskaffas? : - Om avtalsslutet, kravet på garanterad elleverans och den s.k. supplier centric-modellen på elmarknaden
Internal communication is an important factor in organisations today. For many system development teams it?s critical that the communication works well. Without communication, success would be impossible. This study aims to highlight the effect communication has on the members of agile project teams.
Automobike: en cykel med aktiv balans
During spring 2012, six students at the Royal Institute of Technology in Stockholm carried out agroup project in the field of mechatronics as part of the thesis for the bachelor degree. The resultwas a robot with active balancing and the purpose of this report is to describe the development,manufacturing and problems that arose during the project. The finished robot has two wheelsmounted in line with each other, like a bicycle. Measurement data from an accelerometer and agyroscope are used together in a complementary filter for determining the angle from the verticalplane. For balancing, a PID controller was used to control the rotation of a reaction wheel, whenaccelerating causes a straightening torque.
Handhållen kommunikation för produktionsledare
Kandidatuppsatsen skrevs på Göteborgs Hamn, Skandinaviens största hamn. Uppsatsen skrevs isyfte att observera möjligheter med vilka trådlösa kommunikationsmedel produktionsledarna kananvända när de tidsrapporterar. Genom intervjuer och egna observationer visade analysen atthandhållna enheter för tidsrapportering är möjlig i mån om anpassning av handhållen enhet tillverksamhet och målsystemet. Teorin lyfter fram olika möjligheter och komponenter för vadanalysen skall tillämpa villkor, användningsområde, teknologi, objekt och funktioner kommerligger till grund för hur man skall tänka då man implementerar och designar ett nytt eller ettbefintligt målsystem. Resultatet visar att en handhållen enhet är möjlig då man även måste se överett system som passar ihop med målsystem och handhållen enhet samt uppnå de viktiga faktorernasom respondenterna önskar vid övergång från Excel ark till PDA.The thesis was written in Gothenburg Harbor, the biggest harbor in Scandinavia, and was created toobserve what the opportunities are for a change in the ways of communications for the productionmanagement and if there are opportunities for a wireless communication for time report throughhandhelds.
PTAG - aktiv RFID-tag med GPS
Free2Move AB is developing products for the market within wireless communicationand identification, among those active RFID-tags. The company had an idea aboutproviding one of their active RFID tags with a GPS receiver and transmit positions viaan existing RFID protocol. Desire from the company was also the possibility to logpositions and measure temperature. The finished prototype should also be able to beactivated by movement. The company had proposal about components that were to beused in the project.
LOST IN TRANSLATION: Kommunikation förlorad i informationssystem
This study investigates communication and data in information systems. The paper deals, more specificly, with communication in a CRM-system implemented in a Swedish-founded company in Beijing, China. It discusses cultural, political, linguistic and gender based dilemmas that can arise from the use of a CRM-system in an international and bilingual environment. Fifty-nine interviews were conducted in Sweden and in China, either in Swedish or English. The result of this study shows that communication in the information system is affected by factors, that are not originated in technical shortcomings of the system, but rather from cultural, political, linguistic and gender based pre-knowledge among individuals.
Betydelsen av ett fritidsintresse : Fotboll som prevention och identitetsskapande för unga
This essay deals with the subject of communication through Facebook. In this survey we studied 100 youths from Karlstad and their communication habits and behavior patterns on Facebook. The social network site Facebook has since its start in 2004 made a mark in modern communication. Today in 2010 the site has more than 500 million users. This paper wants to study what happens to other types of communication.

Faktorer som påverkar IT-relaterad gruppkommunikation inom organisationer
This thesis builds on the core problem: What Factors Affect IT-related Group Communicationwithin Oragnizations? With sub-questions: How does the daily communication in the workplacepresent itself? How can the individual affect communication? The purpose of this paper is toinvestigate which factors influence group communication positively and negatively, andhow communication affects the daily work in an organization. For this study, the fourinterviewees, from four different organizations, have been selected to participate in astructured interview conducted with the help of an interview guide. To analyse thequalitative data derived from interviews, a method of creating patterns and themes wasused. This is presented by selected quotations from the interviews in order to provide aricher depiction of the collected data.The result could indicate large gaps in both formal and informal communication, whereemail turned out to be one of the biggest single problems.
Implementation of an FFT algorithm using a soft processor core
This report deals with the modeling of a part of the communication system based on the IEEE 802.11a standard which represents the next generation of wireless LAN with greater scalability, better interference immunity and significantly higher speed, up to 54 Mbps. 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM) where modulation is performed by an IFFT and the demodulation by an FFT. After modeling the FFT in Matlab and C, the FFT implementation has been validated using a soft microprocessor core by Xilinx (Microblaze) and the results were compared..

E-post och internkommunikation : en studie av upplevelser kring användandet av ny kommunikationsteknik
Purpose/aim: To investigate individual experiences of how a new communication technology, e-mail, influences a) the structure of the internal communication ? does it for example make networking any easier? ? and b) the form of the persons everyday language.Material/method: A theoretical framework gathered through a literature study and empirical data gathered through interviews with two persons.Main results: Differences and similarities exist between the experiences studied in this paper. The most unexpected result is that the system of e-mail does not seem to be able to create new channels of communication. If anything, it reinforces the structure that already exist. An aspect of decisive importance is the original rules and norms concerning internal communication within the organization..
