MPD-vågformer för helikopterradar

A helicopter based system equipped with a millimetre-wave fire control radar is studied for improvement of the detection probability for moving ground targets. The system is a pulse doppler radar that sends out the electromagnetic wave in repetitive pulses. The frequency in which radar sends this pulse is called Pulse Repetition Frequency (PRF). The velocity of the moving targets is measured by spectral analysis of the pulses received. With this sort of system some targets will not be possible to detect.

Extubering av neurointensivvårdspatienter

Bakgrund: Många av patienterna på en neurointensivvårdsavdelning (NIVA) vårdas med respirator under en längre eller kortare period av vårdtiden. Neurointensivvårdspatienterna bedöms ibland utifrån de kriterier för urträning och extubering som används på allmänna intensivvårdspatienter. Detta kan leda till för tidig extubation med reintubation som följd. Syfte: Redogöra för vilka kriterier som ska bedömas hos neurointensivvårdspatienter inför en extubering. Metod: Litteraturstudie.

Ekonomisk kompensation vid föräldraledighet, vadå? Utifrån arbetsgivarens perspektiv

The purpose with this essay was to analyse the view of parental leave in the public and private labour market. How does the economical compensation affect the parent's use of parental leave, with focus on the fathers "earmarked" months? Were there any differences in private companies and public organisations? We chose to look at past research and theories about father/men's usage of "60 day parental leave" from a point of gender and equality perspective. In regard to our questions we preformed qualitative, semi structural interviews. We picked people at random to interview at both private companies and public organisations that had or had not extra economical compensations except what the social insurance office paid during parental leave.

Energioptimering : Resteffektkylning av mellanlager för använt kärnbränsle (CLAB) Oskarshamn

This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.

BIM förenklar det fortlöpande arbetet genom hela byggprocessen genom att tillhandahålla information om projektet som är relevant, uppdaterad, integrerad, fullt koordinerad och av hög kvalité.

Skarven : ? Produktutveckling av en oljedimavskiljare

This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.

Apples väg till framgång : Bakomliggande faktorer till varför Apple lyckats

This study is intended to give an impartial view of a young and complex program in Sweden titled Product Innovation Engineering program. The purpose of this program is to increase innovation capability in Sweden that will result in new companies, patents and economic growth. The results from this study might give some direction to future innovation initiatives, but should primarily serve as a tool for the PIEp participants. The study will focus on investigating the creation of the program as well as the development of its strategy. From weaknesses and strengths within the strategy of the program the study should also attempt to show its future potential.

Systemutveckling i praktiken - konsten att tillmötesgå den okända användarens krav

ABSTRACT System development has become more and more concentrated on development for the Web and this has resulted in larger target groups. It will most surely continue to be so considering that the Web will be the infrastructure of business and services in the future. A big target group involves that the owner of a system can earn a lot of money from the paying users, but that assumes that the system can meet user needs. If a system on the Web does not satisfy the user?s demands then they will use the competitor?s system instead because it is only a mouse-click away.

Det pedagogiska arbetet inom MSI : Utifrån Bolognaprocessen och UPC

The Pedagogical progression within MSI ? Based upon The Bologna Process and UPC.In a near future several of the European countries will begin working after new guidelines concerning a declaration called the Bologna process. Everything will be done one step at a time and the declaration will change the way the students are being graded, all this for the sake of making the European labour-market moreopened for all of its millions of students.In Växjö this process is in the making, but to adapt to the future demands the school must also change its ways of teaching.To increase its quality the University has put together a procedure of actions to improve the pedagogical working method in all its institutions. In this essay we would like to elucidate how the work with the Bologna process is proceeding within the institution of Mathematics and System Engineering and whatthey do improve their pedagogical teaching. By doing a qualitative case study on the student at the Computer Science Program we wish to find the answers to our questions..

Hisskärna av skalväggar i höga byggnader : Ett alternativ till den platsgjutna kärnan

A common way to stabilize high rise buildings is to use an elevator core built of concrete. Today, we use to build these elevator cores of in-situ concrete. Precast concrete twin wall (double wall) is a semi-finished product that has become more common in recent years. This diploma work studies how the twin wall works out as structural elements in an elevator core. The work also shows some possible ways of designing twin walls and highlights some important parts of the design that will be vital to the stability of the building.    The result shows that it is important to think through where the element joints should be placed.

Windows, RedHat och IPv6 - ett test!

With the huge amount of computers connected to the Internet the IP-addresses are starting to run out. The Internet Engineering Task Force, IETF, have decided that it is about time to exchange the old 32 bits Internet protocol, Ipv4, to a more modern 128 bits protocol called Ipv6. This thesis explores the possibility to install Ipv6 in different operating systems. By testing various operating systems and by set up criteria compare them to each other we give the reader a picture of how the installation is done. We also show which operating systems to prefer if you want to use IPv6.

En jämförande studie av Svenskt Vattens och CAC:s syn på HACCP-processen, En utvärdering och ett praktiskt tillämpande av Svenskt Vattens "Handbok för egenkontrollprogram med HACCP"

Denna rapport, En jämförande studie av Svenskt Vattens och CAC:s syn på HACCP-processen, En utvärdering och ett praktiskt tillämpande av Svenskt Vattens Handbok för egenkontrollprogram med HACCP, skriven av Anna Järvegren Meijer (handledd av Kenneth M. Persson, professor vid Teknisk Vattenresurslära, Lunds Tekniska Högskola och Anne Levin, konsult på SWECO VIAK, Malmö) behandlar kvalitetssystemet Hazard Analysis and Critical Control Points (HACCP) och fokus ligger på tillämpning inom beredning och distribution av dricksvatten.Rapporten består av tre delar. I den första redovisas HACCP-processen och de arbetssteg som Codex Alimentarius Commission har tagit som praxis. Här jämförs också Svenskt Vattens syn på HACCP i Handbok för egenkontrollprogram med HACCP med just CAC:s. Det konstateras att skillnader finns då Svenskt Vatten har valt att inte följa CAC:s praxis till punkt och pricka utan utformat arbetsgången annorlunda.Den andra delen av rapporten handlar om hur användarvänlig Svenskt Vattens handbok är i praktiken.
