Annonser i nättidningar ? kvalitet och placering i målorienterad sökning
This study investigated how banner ads, depending on its quality and placement,can capture a user's attention while searching for editorial content in an online newspaper. Furthermore, the user's search strategy was also studied to see whether it varied depending on the placement of an ad. An experiment was conducted where 20 subjects searched for articles in a Swedish online newspaper while their eye ovement was recorded with a headmounted eye?tracker. In each search task the online newspaper contained either a low quality ad or a high quality ad.
Kvalitetskontroll av utskrifter från Kodak Approval XP4
When using the digital halftone proofing systems, a closer print match can be achieved compared to what earlier couldbe done with the analogue proofing systems. These proofing systems possibilities to produce accurate print match canas well lead to producing bad print matches as several print related parameters can be adjusted manually in the systemby the user. Therefore, more advanced knowledge in graphic arts technology is required by the user of the system.The prepress company Colorcraft AB wishes to control that their color proofs always have the right quality. This projectwas started with the purpose to find a quality control metod for Colorcraft´s digital halftone proofing system(Kodak Approval XP4).Using a software who supports spectral measuring combined with a spectrophotometer and a control bar, a qualitycontrol system was assembled. This system detects variations that lies out of the proofing system´s natural deviation.The prerequisite for this quality control system is that the tolerances are defined with consideration taken to the proofingsystems natural deviations.
Intern materialhanteringsutveckling på Kongsberg Automotive AB
This examination report is a part of a program for Industrial organisation and Economics with specialization in Logistics and Management at Jönköping University. The report contains an analysis of the internal material handling at Kongsberg Automotive, and also an improvement proposal for a new material handling system.The aim with the report is to find a better material handling system and also make an analyse of the existing system. The goal is to shorten the distance for the operators when they order material, and also to increase the productivity.The investigation methods for the report have for the most part consisted of observations and interviews of key-persons who daily work in the production. During some time the actual material handling-system has been observed and some shortcomings have been discovered, and these are also discussed in the report.The shortcomings that have been discovered are for once the indistinct signal that should signal need of material in the production. Some other activities have also been discovered that does not bring any value into the final products.
Shopping Cart Support
This is a product development project which has developed a prototype in order to facilitate for people using mobility devices when they want to buy a larger quantity of groceries. The prototype is a shopping cart composed with the upper part of a walker.Today there are many different types of mobility devices used by elderly and people with physical impairment. According to Myndigheten för samhällsskydd och beredskap (MSB) are accidental falls the most common cause of accidents in Sweden.This project has been using Computer Aided Design (CAD) as a tool to create a visual image of the prototype. The advantage of this is to modify the functionality and performance of the prototype on the computer before the modification takes place in the real model. Using human manikins, the CAD model was rendered in natural surroundings to get as true a picture as possible.
Ett flervariabelt feldetekteringssystem för övervakning av bärlagertemperaturen i vattenkraftturbiner
The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.
Kungliga bibliotekets klassifikationssystem över den svenska samlingen år 1887
We have carried out a study of a classification system for the Swedish collection at The Royal Library in Stockholm from 1887. It was printed in 50 copies. The constructor, Bernhard Lundstedt, and his colleagues used it as guidance in lack of a catalogue. We regard it a local classification system. Little research has been done on old classification systems, but Francis Miksa points out the importance of examining them.
Funktion - Vad är det?
Den här uppsatsen behandlar elevers kunskaper om begreppet funktioner. Det står i uppnäendemålen att eleverna skall kunna tolka och använda enkla formler, läsa enkla ekvationer, samt kunna tolka och använda grafer till funktioner som beskriver verkliga förhållanden och händelser. (Utbildningsdepartementet, 1998). Undersökningen är gjord på tre skolor och omfattar två klasser i är 9 samt en klass i gymnasiet. Vi har genom enkäter och djupintervjuer försökt ta reda på vad eleverna kan inom området.

The Purchase Decision Process Revisited: The Role of the Internet on Swedish Consumer Behaviour
The aim of the thesis was to provide further understanding on how Swedish consumers use the Internet as an information source in their purchase decision process. The subject was investigated from different perspectives: gender, product type and information type. The authors used a quantitative approach, and a survey (n=120) was conducted. It was concluded that men and women are equally influenced by traditional word-of-mouth, but more men than women search for product information online and they are more likely to let their purchase decision to be influenced by it. Women tend more to trust commercial sources.
Skolår 4 elevers uppfattning av likhetstecknet och läroböckernas framställning
Syftet med denna studie var att undersöka skolår 4 elevers förståelse av likhetstecknet. Vi ville även studera hur symbolen presenteras i elevernas läroböcker och mot bakgrund av tidigare forskning diskutera hur detta kan påverka deras förståelse av begreppet. I studien använde vi oss av tre insamlingsmetoder: en kvantitativ undersökning, kvalitativa intervjuer och en textanalys av läroböcker för skolår 3 och 4. Vår undersökning visar att även om eleverna uppvisar bra förståelse av likhetstecknet när de löser uppgifter av strukturell typ, har de svårigheter med att muntligt beskriva likhetstecknets funktion. Textanalysen synliggör att andelen utsagor av operationell typ som framhävs i läroböckerna för åk 3 minskar betydligt i läroböckerna för åk 4.

Handel med utsläppsrätter. Ett effektivt styrmedel på den svenska fjärrvärmemarknaden?
In January 2005 the emission allowance system was introduced within the European Union and the first period ends at the end of 2007. The system was introduced in order to decrease the wastes of carbon dioxide and the system is a part of ratifying the Kyoto ?protocol which first period runs between 2008-2012.The idea of the system is to reduce the wastes of carbon dioxide where it costs less to do so and the expenses for the society therefore are as diminutive as possible. Different theories explain that companies can benefit from environment legislation and can depending on the company?s attitude gain competitive advantages improve its productivity and thereby increase its profitability.With this in mind, the study aims at examining how the introduction of the emission trade system has influenced Swedish smaller companies in the distant heating industry, with focus on the factors attitude, innovation, competition and profitability.
Åsktransienter och överspänningar : En spänningsfylld simulering av elkraftsystemet vid Forsmark 3
A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.
Integrationskatalog - teknisk dokumentation av ett integrerat system
Systemintegration är arbetet med att få IT-system att samarbeta med varandra. Inomsystemintegration finns det idag ett glapp mellan den tekniska dokumentationen och den tekniskalösningen vilket försvårar arbetet med att ta fram och underhålla integrerade system. För att underlättadetta skapades på uppdrag av Ipendo Systems en databasmodell för att kunna lagra tekniskdokumentation om integrationssystem. Lösningen implementerades i Microsoft SQL Server. Underarbetet utvecklades stöd för hämtning av data från integrationsplattformen BizTalk.
