Denna rapport behandlar en undersökning av olika lastbalanseringsalgoritmer i Linux Virtual Server. Undersökningen har gjorts i ett webbkluster (Apache var webbservern som användes) med tre heterogena noder, där operativsystemet var den detalj som skiljde dem åt. Operativsystemen som ingick i undersökningen var Windows Server 2008 R2, CentOS 6.2 och FreeBSD 9.0. De faktorer som undersöktes mellan de olika algoritmerna var klustrets genomsnittliga svarstid vid olika belastning och hur många anslutningar som kunde hanteras av klustret, detta gjordes med verktyget httperf.Undersökningen ger svar på hur ett heterogent webbklusters genomsnittligasvarstid och arbetskapacitet kan skilja sig åt beroende på vilken algoritm som används för lastbalansering. Resultatet visar att den genomsnittliga svarstiden håller sig låg tills en hastig stigning inträffar.

Att arbeta i team är något som blivit allt vanligare på senare tid. Många organisationer har övergivit den traditionella hierarkiska organisationsstrukturen och övergått till att införa en teambaserad organisationsform. Att arbeta i team innebär att teammedlemmarna tillsammans, genom nära och intensivt samarbete, kan utveckla idéer och fatta beslut som inte är möjligt individuellt för var och en av dem. Detta ställer krav på att organisationskultur, interna organisationssystem och ledarskap utvecklas och att de stödjer den nya strukturen. Vårt syfte med denna litteraturstudie är att beskriva ledarskapet av självstyrande team med utgångspunkt i litteraturen.

In 2002 the Norrköping municipality decided to establish a number of supportive teams and one teaching group with the purpose of developing alternative supporting efforts for children with social problems. This development work came to be called BUSS. BUSS today consists of four local teams, team Ett, team Norra, team Torpet and the Mathson School.The teams? focus, beyond the commission from Norrköping municipality, is to reduce the number of children being placed outside their own homes, get them to function in school, develop their self-confidence and social competence. Also their task is to support parents and take up a functional spare time for the children.

Together with Hälsoteknikalliansen the project team recognized the need to improve availability in the staircase environments. This is a difficult environment, especially for our elderly. The staircase leading to and from apartments is such a major obstacle that many people do not dare to go into the staircase leading to their front door. The market study that the project team conducted showed that many were in need of a living support, often a relative, who helped and supported them when they went into these stairs. It also appeared that these people manage everyday life just fine, but they suffer the problems that stairs to and from their apartment causes.

The idea to develop  a platform for a PID-controller came from the need to control the temperature in  an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.

This is the end report of my final exam at Medieteknik. It covers the planning, work process and review of a Flash based web application that I set out to do. The goal was to create a user friendly, interactive e-shop with embedded functionality for playing music, displaying rich media content and researching possible payment solutions, to enable buying music files online. The project involved creating the user interface, the programmatic functionality of a Flash client (an SWF file). Also, setting up an Apache HTTP Server and establishing a working ?bridge? between the Flash client and the web server with Flash Remoting components and AMFPHP.

Earlier research has shown that generational differences between younger-supervisors and older-workers may cause tensions that lead to team ineffectiveness. There is however still a lack of research in this area. This thesis presents possible tensions that might occur between a younger supervisor and an older worker due to their age and generational affiliation, and how these tensions affect the team dynamics. The empirical data collection was limited to the boundaries of the dental care industry where these generational/age differences between younger supervisor and older worker are common. The thesis looks at the tensions from a qualitative perspective and data was collected in the form of in-depth interviews with selected dentists and nurses.

ABSTRACT This essay is about traffic analysis of Web servers. The purpose is to investigate if companies analyse the traffic on the Web server and if they use this information to create more than simple statistic reports. The questions that we will answer are the following: ? How common is traffic analysis on the Web server among companies? ? Is the Web administrator limited in analysing the Web traffic, if the company has the website on a Web hotel? ? Does the company uses the results they get from analysing the traffic on the Web server for updates and changes on the Web page? To answer these questions we made a questionnaire investigation by telephone interviewing the companies? webmasters. The extent of the investigation was 20 companies in Blekinge.

The mainpart of this thesis is about the developing of a new analysis tool to be used in Zenicor Medical Systems AB ECG-system. The primary task of the system is to simplify the ECG survey for patients who suffers from different kinds of arrythmias, for example heart fibrillation. With this system is it possible for the patients to do their ECG survey by them self at home and then send the signal with their telephone or mobilphone to a server. The equipment used to do the survey is not bigger than you can have it in a pocket and this results in a bigger flexibility for the patient. A doctor can connect to the server and analys the ECG-curve and follow up the patients condition..

Den ha?r studien a?mnar ge sto?rre fo?rsta?else fo?r den roll skillnader i nationell kultur spelar i globala virtuella team, ett arbetssa?tt som i allt sto?rre utstra?ckning anva?nds av globala fo?retag. Studien identifierar fyra byggstenar som ligger till grund fo?r teamets prestation; fo?rtroende, ledning, relationer och samarbete samt kommunikation. Utifra?n dessa teman ges en litteraturgenomga?ng som mynnar ut i en kvalitativ intervjustudie utfo?rd i ett globalt virtuellt team pa? IT-fo?retaget Tieto.

SAMMANFATTNING Problem: Det finns många tankar om organisationer och hur de ska styras. Förr handlade det om att styra företagets olika resurser för att uppnå lönsamhet. I dag krävs det mer av företagen och dess traditionella organisationsformer sätts på prov. För att utvecklas och framförallt kunna konkurrera i den allt mer föränderliga omgivningen krävs det att organisationerna är öppna för nya tankesätt. Det pågår en övergång från traditionella organisationer till processorienterade organisationer.

Varför stannar många skolor vid en yttre organisation i team medan utvecklingen av dess inre arbete går betydligt långsammare. Utifrån en fallstudie på en F-9 skola undersöks lärares och skolledares föreställningar om de hinder och möjligheter som finns för att kunna utvecklas till väl fungerande team. Vem eller vad är det som hindrar?.

This master?s thesis was performed at PartnerTech AB in Åtvidaberg. It addresses the problem of managing test results obtained from testing electronics manufactured by PartnerTech. PartnerTech has developed a test system, called Tor, which performs tests on manufactured boards and stores the test results in files. The Tor system consists of both hardware and software part, where the software runs on an ordinary PC with MS DOS/Windows 2000.
