By using modern methods of casting concrete, cast in place can get more effective and industrialized. A modern method is self compacting concrete. By using this type of concrete, advantages like improved working environment and rationalized construction can be reached. Because the concrete doesn?t need to be vibrated, the amount of staff on site and the noise can be reduced.

The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.

Have you encountered problems when you are unlocking a door? Perhaps you have had your hands full when you needed to unlock the door? Or, you might be suffering from a disease and have difficulties to put force on to small objects. To solve these problems there are different options. The most common alternative is a key button. With the key button, you do not need turn the pinion to unlock.

Sedan radar började användas under första hälften av 1900-talet har duellen mellan radar och signalspaning pågått. Genom att utnyttja radar har alltid en medveten risk tagits, risken att bli upptäckt av motståndarens signalspaning. Duellen gavs möjlighet att ta en paus då radarsystem med låg uteffekt introducerades på marknaden under slutet av 1980-talet, nu fanns plötsligt en möjlighet att använda radar samtidigt som de samtida signalspaningssystemen inte kunde upptäcka dessa radarsystem. I föreliggande magisteruppsats i krigsvetenskap med militärteknisk inriktning undersöks räckviddsförhållanden mellan dessa radarsystem och signalspaningssystem. Genom scenarier i den marina arenan försöker jag värdera de taktiska vinster en användare av radar med låg uteffekt kan göra.

This thesis presents the theory behind prototyping and user interviews as parts of requirements analysis. It further discusses how these were used in the development of a budget planning application. The implemented Web-based solution uses a new component-based design rooted in a Model-View-Controller architecture. The application is used today with complete success at the Department of Computer and Information Science at Linköping University..

Det är väl belagt att patienter postoperativt och inom intensivvården drabbas av en funktionell sömnbrist i form av störd dygnsrytm, stort antal uppvaknanden och rubbad sömncykel med underskott av djupsömn och REM-sömn. En delförklaring till sömnbristen är de generellt höga ljudnivåerna på intensivvårdsavdelningar. Syftet med föreliggande pilotstudie var att undersöka huruvida öronproppar kunde förbättra den upplevda sömnkvalitén för patienter inom intensivvård och postoperativt. Tjugotvå patienter från två intensivvårdsavdelningar, en hjärtintensivvårdsavdelning och en postoperativ avdelning deltog i studien. I interventions-gruppen sov elva patienter en natt med öronproppar och elva patienter som sov utan öronproppar utgjorde kontrollgrupp.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

As part of an Agile developing team I have in my role as interaction designer also tried to evaluate the ?iPhone Human Interface Guidelines?. With action research I have taken actions to change the workflow and to see what there can be done to make the guidelines more motivating to use. Action 1 tried to make the iPhone components more available and it suceeded, action 2 tried to make the guideline more available in whole and did not work as it was designed to do. The guidelines did not work as a source of inspiriation and I and my fellow designer distanciated us from it.

Our project is divided into two parts, one production and written report. The main focus was the production part, were we used PHP to create simple solution for handling SMS and MMS with direct communication with the mobile operator server. We communicate with sockets and can handle CIMD2 and MM7 protocol. To get our components easy to use we have created two classes to handle SMS and MMS. To demonstrate our technical platform we created a website were you can create an account.

At the plant of Sandvik do Brasil in São Paulo there is a need for improving the transport of inserts between the plant building and the stock building. The idea is to install a system with an Automated Guided Vehicle (AGV) to take care of this transportation. The purpose of this report is to present which demands there are on the system and to find the best solution according to the demands.To conclude this work a study was made of the plant and the AGV technology was examined. Several providers of AGV solutions were contacted to get information about prices and detailed solutions.The conclusion was that the most suitable system for this application is a small unit load vehicle using inductive wire as guiding system..

This document?s content is the final report of the master´s dissertation Magnus Hällström did during springtime of year 2013. The dissertation?s subject is 802.11s wireless mesh networks with streaming video as a focus point.  During the dissertation a wireless mesh network was set up with different attached cameras for streaming video. A sun panel solution was also tested with the goal of creating a package with a self-configuring network node streaming video, powered by nothing but solar energy. .

Industrialization of construction is by some considered to be a solution to the building industry's problems about the lack of quality, high production costs, low productivity and poor environmental adaptation. Meanwhile, industrialized construction partly earned a bad reputation after the million housing program. As large-scale projects where promoted during this period, it worked very well to use the technique of construction elements. In the mid seventies though, criticism arose which claimed that the aesthetic qualities had been deprived in the corporates effort to make housing production as efficient as possible.Tyréns, Derome and CBBT (centre for building and housing in wood) cooperates in a development project to develop a building system for 4-8-storey buildings, consisting of three platforms: a technology platform, an IT platform and a processing platform. The technology platform consists of flexible, industrially built flat modules of wood and from this platform the subsystem stairwells, is broken out.

The purpose of this report has been to develop an administrative web interface. The web interface is to be used by the company Zidango and it is going to make it easier for them in their daily work of running a web portal. The interface had to be developed so it would fit in Zidangos web portal. This meant the work had to be done in the framwork Struts and mostly in JAVA. Thereforeis a shorter theory chapter included in the report that discusses frameworks.

Ett vanligt förfarande i parapsykologiska s.k. ganzfeldexperiment är attmed hjälp av vitt brus, som spelas upp i hörlurar, försöka omslutaförsökspersoner i ett slags totalt och oföränderligt perceptuellttillstånd. I föreliggande studie undersöks konsekvenserna av attanvända vitt brus som bakgrundsljud. 30 försökspersoner har lyssnattill åtta ljudslingor innehållandes fyra typer av brus vid två olikaljudnivåer, för att sedan i ett enkätformulär uppskatta hur dessa ljudpåverkat dem. Resultatet visar på signifikanta effekter av så välbrustyp som amplitud, och dessutom en signifikant interaktionseffektdem emellan.

This essay takes the three models from Allison and Zelikow book Essence of decision and applies them on the Swedish defense system. After the cold war the Swedish defense system had to undergo changes to be a more modern defense and be able to defend Sweden against threats. To also be able to cooperate with other countries in peacekeeping operations the Swedish defense had to be reorganized. The solution was to change direction from a defense system that was organized for invasion to instead be a movable defense ready for any challenge in Sweden or abroad. This reorganization will be analyzed according to the three different models..
