Demokrati, ett uppdrag för skolan : En implementeringssudie angående demokratiuppdraget i skolan

The current study sought to examine if post-produced semantic memory cues are a good aid for memory recall. It also focused on remembering units with a meaning, instead of just remembering lists of words. In the current study a factual text was used where the participants were tasked with recalling as much information as possible either with the aid of cues (keywords written by the participants themselfs), computer with Internet or no aids at all. The results showed that keywords are significantly better for memory recall. The results were discussed in regards to modern models describing semantic memory.

Time Machine Computing for Media Improvisation

C3LOOPS is an application for DJs and VJs based on surface interaction. A system is said to be based on surface interaction if it presents content on a two dimensional, endless surface that a user navigates through zoom, pan and incremental text filtering where processing is tightly coupled with the content without breaking the workflow. C3LOOPS is designed to encourage improvisation and collaboration. During improvisation changes occur rapidly. Allowing navigation through time as well as the two spatial dimensions of an interaction surface the possibility of unlimited undo operations opens up.

Energieffektivitet Hos Dubbelskalsfasader

Today multi-touch technology is the basis for many new techniques designed to improve interactions with computers and mobile devices. It seems that multi-touch screen interface makes the user handling very natural in the sense that there is no need for a manual in how to interact with the object on the screen. The aim with this paper is to establish a fundamental set of design principles intended specifically for large multi-touch interfaces. To reach this goal we have implemented a couple of sub-goals beforehand: It was essential that we acquired a good understanding of the current state of the multi-touch interface and the different implementations that exist today. To make this possible we constructed a multi-touch display, "Rosie". Knowing how the hardware is produced today will help us understand the limitations and also the possibilities of the design implementations today and in the future. We also needed to devise a sound interaction design process that conveys the modern designers work.

Ny inmatningsfunktion för Arcomas detektorhållare

Arcoma is a company that develops and manufactures X-ray equipment for hospitals. One of the most crucial components is the digital detector. Due to the high cost it is made removable so it could be transferred and used in other X-ray apparatus. The detector is placed in a so called detector holder. The current detector has a rectangular shape which sometimes requires a 90 degree rotation to match the shape of the patient.

This project is therefore using the designprocess human-centered design for interactive systems. The process includes four basic elements and provides guidelines for user-centered design. These parts are analysis, prototyping, implementation, and evaluation (Johansson.

Analysverktyg för webbsidor med JavaScript

New technological innovations like tablets and smartphones have a taken significant market share on the web and puts new demands on webpages, the user interface and compatibility among different client devices. The full test of a web-based system prior to the publication is often regarded as an important part of the process to create a complete and successful website. This bachelor thesis investigates the possibility to analyze mobile-adapted web sites using a system that first records the visitor's activities and then replays them for an expert analyst to provide valuable information to developers about how their site can be improved.The essay begins with a litterature study on today's most common web development tools and then examines the possibility to apply them during the development of the analysis tool. The work also describes two methods, pair programming and waterfall method used during the project. Three different evaluation methods are presented and one of the models is applied on the finished system.The project results in a web-based analysis tool written mainly in JavaScript using the jQuery library.

Byte av kontaktdonsgränssnitt för Scania bromssystem

This master thesis was carried out at Scania in Södertälje, Sweden. It investigates the possibility of changing a connector interface that is used when there is a need for splicing the wheel speed sensor and thereby determine the consequences.The problems that exist with the current connector interface occur during assembly, as more time is required to complete a connection in a reliable manner. A complete connection requires joining the male and female connector, insert the connection into a protective retainer and then strap a cable tie on each end of the retainer. This process makes it more time consuming and it requires 20-30 seconds to complete the connection. Solving this problem would save time and enable easier assembly, therefore resulting in economical benefits.This thesis was accomplished through discussions with different sections at Scania, studying available documentations, observations during assembly, writing a requirement specification and contacting suppliers.The aforementioned methods resulted in four connector suggestions, the DT and DTMH connector from Deutsch, MCON connector from TE connectivity and MLK connector from Kostal, each of them compliant with the set demands of the surrounding environment.

Quantitative thermal perception thresholds, comparison between methods

Skin temperature is detected through signals in unmyelinated C-fibers and thin myelinated A?-fibers in the peripheral and central nervous system. Disorders in thin nerve fibres are important and not rare but difficult to diagnose by the most common neurophysiological methods. In this pilot study different methods for quantitative sensory testing, QST, were compared to give some ideas about which method could be the most efficient to use in order to point out injuries of the sensory system in clinical practice. The comparison was made between Békésy (separate warmand cold thresholds) and Marstock test (combined warm and cold thresholds).

Förtroendebyggande i finasiella analystjänster

This bachelor thesis aims to analyse the Swedish mortgage market and investigate whether it is in a current price bubble or not. Comparisons have been made with Denmark, a country with a market similar to Sweden?s, and where the mortgage market faced a price bubble that crashed in 2008. The housing market in Stockholm has been analysed as a separate market, as it differs from Sweden as a whole in prices and underlying factors to increased prices. The conclusion of this thesis is that not Sweden, nor Stockholm, is currently in a price bubble at the mortgage market.

The Current Emphasis : en diskussion om flödesfilosofi och planering

The current planning philosophy is based on a political utopic modernism founded during the first part of the 20th century. The focus is, in planning a defined area, to maximize the internal efficiency and to create a competitivesociety. During the latter part of the former century globalization changed the context, thus creating the need for a new way of approaching physical planning. This paper shows that the historical and philosophicalmetaphor of flow can be applied to meet the demands in the global city. It also shows how the edge, as where interaction takes place, is an important part of the content that has to be defined.

Avbrottsfri Kraft med användning av ultrakondensatorer

The supply of uninterruptible power can be applied to many areas wherecontinuous operation is highly prioritized.The application of uninterruptible power for motor operation is facilitatedusing a frequency converter. Direct current operated frequency converters canbe applied directly to the power reserve which removes the need for additionalpower-converting.Batteries have long constituted the power reserve but advancements inthe development of ultracapacitors have created a viable substitution. Ultra-capacitors have high energy storing capabilities and can be applied to highpower applications.Maxwell is a leading manufacturing company of ultracapacitors and pro-vide different modules with built-in solutions for voltage balancing. Unevenvoltages between series-connected capacitors is a phenomenon caused by vary-ing capacitance. A configuration containing Maxwell?s 56V module is createdand constitutes the power reserve in the simulations.The discharge simulation shows a significant current that could damagethe system.

Implementing a receiver in a fast data transfer system : A feasibility study

This report is an outcome of a master degree project at Linköpings University in co-operation with Micronic Laser Systems AB. The purpose with this master degree project was to investigate how to implement a receiver in a data transfer system. The system consists of several data channels, where every channel consists of three parts: driver, transmission lines and receiver. The driver send low amplitude differential signals via the transmission lines to the receiver that amplifies and converts it to a single-ended signal. The receiver has to be fast and be able to feed an output signal with high voltage swing.
