This thesis is performed at Saab Bofors Dynamics in Karlskoga and investigates a technique for ranging with laser pulses. The investigated technique is called Constant Fraction Detection (CFD). Described briefly, the received laser pulse is split into two equal parts, where one part is delayed half the pulse width and inverted. This signal is added to the original pulse. The resulting curve has the shape of a laying S and the detection of the zero level is used to stop the time measurement.

As trucks are getting more and more advanced, information about their weight has become a key factor for controlling them in a more fuel efficient and safe manner. Knowing the mass of a heavy duty vehicle in real time has been a difficult challenge for the truck manufacturers. With the processing power for electronic control units in trucks steadily increasing, more advanced algorithms for calculating the mass has been developed, but at the moment there still is a wish for better performance.Since there is a lack of good information regarding the external forces acting on the vehicle, forces that depends on the slope of the road, foundation of the road and the wind, the methods have to be able to disregard these. Such an approach, based on an indirect least square solution, has been evaluated in this thesis. The results have been promising and based on these a recommendation about further evaluation has been made..

Saab har utvecklat en produkt, Remote Tower, som tillåter flygledningen att fjärrstyra en flygplats, det vill säga att övervaka och kontrollera en flygplats på distans. Ett viktigt verktyg för flygledarna är VCS, Voice Communication System, som är Saabs egna röstkommunikationssystem, där både radio- och telefonkommunikation ingår. VCS används för att kommunicera med piloter och markpersonal på flygplatsen. Målet är att i framtiden kunna fjärrstyra fler flygplatser samtidigt, och då finns ett behov att visualisera de inkommande samtalen från de olika flygplatserna i realtid. Detta för att undvika ett scenario där flygledaren missar ett samtal.

Language impairment affects the ability to communicate. Children with languageimpairment have difficulties in using language in interaction to various degrees, and the contributions of the conversational partner are of great importance. The use of languagein interaction can be analysed by means of conversation analysis. The purpose of thepresent study was to study interaction of a group of pre-school children with language impairment with four different conversational partners. These were a peer with languag eimpairment, a peer with typical language development, a pre-school teacher and a parent.

To be able to measure high-surge voltages and transients with short rise times youneed measuring instruments with a high sampling frequency and large Bandwidth.These surges and transients occur primarily at lightning but can also occur at forexample at connecting errors at an electrical switch-gear. This report describes thework with finding two solutions for measuring and log data from these surges andtransients. One temporary solution where a measurement program has beendeveloped. A second solution where different company solutions have been analyzedto decide which fits best. For these measurement solutions two solutions for bringingdown the voltage has been used.

The aims were to investigate the public awareness of aphasia in a Swedish sample and examine if knowledge of aphasia relates to gender, education or age. Participant?s sources of knowledge of aphasia were examined. A total of 153 individuals, aged 18-90, were surveyed. Participants were categorized into three groups; heard of, knowledge of and not heard of aphasia.

Taltidningen är en inläst tidning som personer med svårigheter att läsa en vanlig tidning kan få. Tidningen sänds förvrängd via radio så att endast prenumeranter skall ha tillgång till den. Förvrängningen kräver att prenumeranter har en särskild typ av mottagare hemma. Mottagaren som används idag spelar in tidningen på ett kassettband som sedan kan lyssnas av på vilken bandspelare som helst. Mottagarna är dock dyra att underhålla och det är svårt att få tag på nya.

Free2Move AB is developing products for the market within wireless communicationand identification, among those active RFID-tags. The company had an idea aboutproviding one of their active RFID tags with a GPS receiver and transmit positions viaan existing RFID protocol. Desire from the company was also the possibility to logpositions and measure temperature. The finished prototype should also be able to beactivated by movement. The company had proposal about components that were to beused in the project.

The master thesis ?Mechanical Integration of an IR-detector in a Micro Cooler? has beenperformed at FLIR Systems AB in Danderyd. FLIR Systems is a world leader in the design,manufacture and marketing of thermal imaging camera systems.The thesis project is divided into to two areas, Production Method and Noise.The Production Method concerns the positioning of a detector on the cold finger within the IRcamera.The detector has to be positiond with very high accuracy at the center of the cold finger,so it can be placed in line with the optical axis to avoid movement of the picture during zooming.The positioning of the detector is at present done with the help of specially designed guides on aplate on top of the cold finger. The design workes well but the special machining needed for thisplate is very expensive.The goal concerning the production method was to derive a new more cost effective method forthe assembling and positioning of the detector on the cold finger by replacing the guides on theplate with a reusable equipment or some other alignement operation.Several concept ideas have been generated with the help of concept generation methods in theform of concept classification trees and concept combinational tables. Two of these conceptswere selected to be further refined.

The purpose of this essay is to shed some light upon the children who grew up in Sweden after their parents fled the war in former Yugoslavia. Did the parents spread their own opinions about the other ethnicities which they fought against in the war to the children, even though they live in a new country? And if so, was it an act of patriotism for the country they once lived in and who was to blame for the war? Did the children who grew up in Sweden share the same attitudes as their parents? To find out about this we used interviews with four people, all with heritage from former Yugoslavia, Bosnia and Croatia. What we found out was that the thoughts from the parents partially were passed down to their children, even though the children thought that they had formed their own opinions. In this case the thoughts didn?t relate to any kind of patriotism or who to blame for the war, they rather believed that they shouldn?t blame the other ethnic groups for the war.

The purpose with this thesis is to illustrate companies? way of using Key Account Management in the organization. We developed the four following research questions: Why do companies choose to use Key Account Management? How do companies identify and choose their key customers? How does a key account manager work? How do the skills needed by a key account manager look like? The results showed that KAM offered several important benefits, mainly of economical characteristics. Identification of the key accounts was mainly conducted through certain economical criteria the customers had to fulfil.

This report is regarding an electrical installation of an alarm system on a post fishingboat called Andromeda. The background of the installation was an earlier andinadequate alarm system that led to a motor failure. The ship was taken out of serviceand was sold to Björn Magndahl who rebuilt it to a yacht.The project was conducted partly by developing the existing systems, partly bydocumenting the work by means of electrical blue prints. Except the alarm systems, aninstallation of the frequency control unit for the bow thruster was installed.The installation was working fine and the outcome of the documentation was handedover in a form of a binder during the test drive of the systems and the assignment wasapproved..

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.
