Redan 1899 skrev Woodworth om iakttagelser av effekten av visuell feedback på rörelser. Sedan dess har ett stort antal studier berört ämnet och studerat effekterna de medför. Denna studie anser att det finns brister i kunskapen om visuell feedbacks effekter inom vardaglig användning. Genom att låta deltagare använda och utvärdera instanser av en bokningsplattform för biljetter till ett event har studien observerat användarens upplevelse och effektivitet under processen.Den insamlade datan analyserades via variansanalys men lyckas inte avfärda nollhypotesen. Studiens resultat visade ingen korrelation mellan närvaron av visuell feedback på hover-funktionen och användarens effektivitet och upplevelse.

Possessory liens and legal liens are two securities that has been the subject of debate from legal scholars for quite some time. Possessory liens are often viewed as a weaker security compared to legal liens. However, upon closer examination it turns out that possessory liens in most cases provide the the same opportunity to sell the property withheld as security. This possibility makes possessory liens resemble, if not be identical to, legal liens. Both securities arise by operation of law and grant the right to both withhold and sell property in the event of non-payment.

The goal of this master thesis is to show the benefit of using computer games of the type First Person Shooter, FPS in the field of military simulations. The main focus in this is around a couple of topics. Creating the AI that controls the behaviour of the computer-controlled characters, the bots. Create an environment where it is possible to supervise the bots and also design a framework that enables cooperation between a group of bots, a squad. The result is Total Unreal Studio, TUS, a program where it is possible to add bots to a squad, connect them to a game server and inspect what the bots are doing.

Following the implementation of IFRS with yearly impairment tests, the question of correlations and causalities between impairments and investors? decision making is gaining interest in academia. This essay will study the relationship between significant goodwill impairments, communicated on the Nasdaq OMX Stockholm webpage between the years 2005-2009, and the impact those announcements have had on investors? decision making. Furthermore, the causality behind the impairments will be in focus.

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.

The gathered texts and letters from Ali Ibn Abi Talib, found in the book Nahjul Balagha,constitute one of the most important writings of Shiite Islam, next the hadits and the Quran.Imam Ali´s ethics and moral approach in Nahjul Balagha, is considered by imam Ali, to beseen as a guideline for both individual purposes as for any kind of governance. The esotericteachings, about truth and justice in Nahjul Balagha, should therefore probably have been of agreat concern to Ayatollah Khomeini and the Islamic revolution.This essay will from an deductive approach, on a relatively contemporary historic event, try toanalyze Ayatollah Ruhollah Khomeini´s interpreting on imam Ali´s texts and preaching inNahjul Balagha. The Islamic revolution, as the Islamic Republic of Iran, led by AyatollahKhomeini, was confirmed as both brutal and violent. My ambition in this essay, will there forconcern a possible interpreting on justice and political rule, from Ayatollah Khomeini and theIslamic Republic of Iran, on imam Ali´s teachings in Nahjul Balagha..

Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the uncertainty and its economic and environmental consequences.The method used in this report is based on three validation methods; empirical validation, analytical validation and comparative validation. The analysis was carried out for five multi-family dwellings in Uppsala with installed meters for energy measurements. One of these objects, Klockarlunden, was studied in more detail than the others.The results show that the deviations are between 10 and 29% for the studied objects, which means that the uncertainty is estimated to be at least 29%. All simulations underestimate the buildings need of energy. The simulation for Klockarlunden can predict the energy consumption to be within the range of 46-98 kWh/m2year with 90% confidence level based on the current uncertainty.

Tidigare studier har gett stöd för att igenkänningsminnet understöds av minst två processer: erinring (recollection) och familjaritet. Detta testades i två beteendeexperiment, inom ett Remember/Know paradigm (experiment 1) och ett Ja/Nej paradigm där Receiver - Operating Characteristics (ROC) beräknades (2). I ett påföljande Event - related potentials (ERP) experiment undersöktes vidare distinktionen mellan minnesprocesserna under återvinning. Deltagarna studerade namn med två former av pre - experimentell familjaritet, namnfrekvens och celebritet, vilka kombinerades till ortogonala variationer av dimensionerna. Frekvens operationaliserades som antalet träffar i den nationella telefonkatalogen och celebritet som antalet träffar i massmediala webbsidor.

Denna rapport beskriver det examensarbete som utförts på Calix AB under vårterminen 2013. Calix AB tillverkar värmare för bland annat batteri och kupé till fordonsindustrin. Uppdraget i detta examensarbete var att göra en omkonstruktion på BEV-heatern (Battery Electrical Vehicle) som är en batteri- och kupévärmare till el och hybridfordon. Problemet med den nuvarande konstruktionen är att den bygger på delar från äldre värmare till fordon med förbränningsmotorer, samt att konstruktionen inte är lämplig för produktion i större serier. Krav som Calix AB hade var:Integrerat ChassiMinimera tryckfallUnderlätta montering och tillverkningUppfylla standarder satta av fordonsindustrinKunna monteras ?in-line? i fordonetFör att kunna genomföra projektet var vi till en början tvungna att få kunskap om hur den befintliga BEV-heatern fungerar.

Jag vill fånga och bevara känslan av bergets inverkan på området. Längs med vägen kommer kommersiella lokaler att finnas. Dessa är flexibla och kan husera en mängd olika aktörer; caféer, gallerier, utställningar, småbutiker, kontor osv.Det de har gemensamt är sikten tvärs igenom byggnaden. Står man på gatan utanför uppfattar man fortfarande berget i bakgrunden genom lokalen.En ny mötestplats genereras. Hornstulls nya torg binds samman med Hornsbruksgatan.

Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.

The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.

In the spring of 2014 Sweco Systems AB were commissioned to design a ventilation system for a newly built preschool in Linköping. Terms from the client was that it cost efficiency would cope with the energy demands that are placed on the building. The unit chosen was a cross-flow heat exchanger, and this work is to compare it with two other heat exchangers to see if a more energy and cost efficient could have been chosen. The heat exchangers that was chosen for the comparison was a rotating- and a counterflow heat exchanger. Simulations have been made to the different heat exchangers by the manufacturers.

Arbetsterapi är ett ämne som framhäver hälsa och välmående genom aktivitet. Det huvudsakliga målet som arbetsterapeut är att möjliggöra för personer att delta i aktiviteter i det dagliga livet. Virtual Reality är en simulation där datorgrafik används för att skapa en tillsynes realistisk miljö och denna värld är inte statisk utan integrerar med användaren. Syftet med denna litteraturstudie är att kartlägga hur och varför Virtual Reality kan användas av arbetsterapeuter. En systematisk litteraturstudie genomfördes och efter databassökning uppkom 14 artiklar som via en manuell sökning kompletterades med ytterligare 5 artiklar.

Denna uppsats undersöker effekter av psykologisk debriefing och avlastningssamtal efter traumatiska händelser hos brandpersonal. Enkätstudiens fokus låg på brandpersonalens känslomässiga påverkan av traumatiska händelser i arbetet. Femtionio personer deltog i enkätstudien, varav 91 procent upplevt en traumatisk händelse. Det fanns inga signifikanta skillnader i posttraumatiska stressreaktioner och psykologiskt välbefinnande hos brandmän efter traumatisk händelse beroende av huruvida brandmännen deltagit i tidig intervention i form av avlastningssamtal, psykologisk debriefing eller inte medverkat i någon form av tidig intervention..
