Är vi artiga mot virtuella agenter?
The CASA-paradigm, Computers Are Social Actors, was introduced in the book "TheMedia Equation" by Reeves and Nass. One of their experiments concluded that we tend to be polite to computers in the same way as we are to people. In this study I have replicated Reeves and Nass experiment but instead of a text-based interface I have used a virtual agentin order to find out if we are polite to the agents, or still to the computer. Two experimental setups was conducted. The two setups had a common first part that was carried out on onecomputer with one agent.

Abstract
I have made a Website called ?Art school? for Liljevalchs art Gallery, Culture
administration in Stockholm and Culture school in Stockholm.
It is with scholarship from these that this Website has been possible.
The work whit the ?Art school? started in the autumn of 2005 and ended in May
2006 on distance from Stockholm towards Blekinge technology school in Karlshamn.
The Webb place is for the general public, but most for people who have interest
in art and for those how want to learn more painting in different mediums. This
Websites I name: oil, watercolour, acrylic, coal, gouache, and graphite. On
each one of these mediums you?ll get to know about their history, what
technique they have, what sort of material you need, practise and tip.

AbstractTrendanalys av rapporterade störningar vid de svenskakärnkraftverkenAnalysis of trends in reported safety-related events atSwedish nuclear power plantsSafdar KargarThis degree project was conducted at the Swedish Radiation Safety Authority (SSM)as part of the bachelors program in Nuclear Engineering at Uppsala University duringthe spring of 2011.The Swedish Radiation Safety Authority (SSM) has developed a Windows baseddatabase called ?ASKEN? during later years. In this database more than 12 000 eventreports are stored sorted in three categories, category 1, 2 and 3. The databasecontains events from the start of Oskarshamn 1 in 1972 till present time.All nuclear power plants in Sweden are obliged to report any deficiency in theirbarriers and/or the defense in depth in obedience to SSMFS 2008:1.When a failure is detected or there is reasonable suspicion of a deficiency, the eventreport should be classified as a deficiency of category -1, 2 or 3 [1].The event reports are logged and archived in the register of SSM. The SSM task forceAnalys av Störningar på elproducerande Kärnkraftverk (the ASK-group), evaluates allincoming event reports and categorizes them according to established criteria.The aim of the project is to study and analyze the event reports in the database andidentity interesting observations and trends which should be investigated morethoroughly by deeper analysis to establish any positive or negative trends of reportedevents. .

CARABAS is a long wave airborne ground radar that has been developed bySAAB Microwave Systems and will now be mounted on a small helicopter, Schweizer 300.The antenna should be able to fold up and down. When the radar is in use the antenna islowered and under transport, start and landing the antenna is folded up. An emergency dropfunction should also be included in the design of CARABAS III.The extent of this report includes construction of the antenna, frame structure attached to thehelicopter, mechanism for folding the antenna up and down and mechanism for emergencydrop function. The mechanical design of the antenna and frame structure is based on modaland stress analysis, vibration measurement of Schweizer 300 and frequency analysis, andcalculations regarding aerodynamic drag and mechanics.The exciting frequencies of the helicopter and accelerations at those frequencies weredetermined by vibration measurement and frequency analysis.
Säker grannupptäck i IPv6
The IPv6 protocol offers with some new functions, one of them is auto configuration. With auto configuration it is possible for nodes, i.e. hosts and routers, for automatically associated with IPv6 addresses without manual configuration. Auto configuration it is another protocol as it uses Neighbor Discovery protocol (ND) messages (ND is mandatory in the IPv6 stack). The main purpose of ND is that nodes can discover other nodes on the local link, perform address resolution, check that addresses are unique, and check the reachability with active nodes.There are exactly the same vulnerabilities of IPv6 as IPv4 and is now exception, ND if not properly secured.

?Det är som att lägga ett pussel? Intensivvårdssjuksköterskors upplevelser av kommunikation med lätt sederade, respiratorvårdade patienter
Att vårdas i respirator innebär att den verbala kommunikationsförmågan förloras, vilket kan medföra känslor av frustration och maktlöshet hos patienter. För att uppnå en vårdande relation är samtalet av stor betydelse, vilket försvåras om kommunikationsförmågan är nedsatt. Syftet är att beskriva intensivvårdssjuksköterskors upplevelser av kommunikation med lätt sederade, respiratorbehandlade patienter. En kvalitativ ansats har använts. Halvstrukturerade forskningsintervjuer utfördes med åtta intensivvårdssjuksköterskor från två sjukhus.

Effektivisering av EPC projekt : Fallstudie Johnson Controls
In todays society the demand on companies to deliver better project management is crucial for them to survive. The higher demands from clients make older project management weak and unreliable. In the constructions sector more and more companies are created and the competition is higher than ever. The clients are aware of the higher competition in the construction sector. This has resulted that construction companies must now make their project management more efficient to create better projects and better relationship with clients. The purpose of this thesis arose from this problem in the construction sector.

Till storms, till havs, var man på vakt : En jämförande studie om förhållandet mellan uppgifter och teknik hos Sjöräddningssällskapet
Precis som många andra domäner har frivilligorganisationen Sjöräddningssällskapet (SSRS) påverkats mycket av den tekniska utvecklingen som skett de senaste decennierna. Den har bland annat inneburit att SSRS båtar har fått mer och mer högteknologisk utrustning. Samtidigt har de frivilliga sjöräddarnas kompetens och kraven på deras kompetens, förändrats i takt med att den svenska fiskeflottan förminskats. Idag består SSRS aktiva medlemmar av personer med huvudsysselsättning bortom den marina domänen. Den här studien gör en bred kartläggning över organisationen för att kunna jämföra förhållanden mellan vilka uppgifter och mål som finns hos SSRS med vilken teknik som finns tillgänglig och hur arbetet utförs i praktiken.
