The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Since the beginning of the internet the criminal world has used the medium as a platform for operation.This dark web is a domain where illegal sites are flourishing due to the possibilities offered by newtechnology. Net-based criminal activity is a challenge for society as it uses hard proof technologicalsafety measures to avoid the law. Silk Road is the most prominent example, an online illicitmarketplace where drugs and illegal substances are being traded based on conventional e-commerceconcepts. This paper argues for trust as an important factor for the survival of illicit online trade andapplies existing theories on e-commerce and virtual communities. To identify patterns of trust andcommon trust-based issues among Silk Road users, a netnographic study was conducted on the site?sdiscussion forum.

The aim of this paper is to map out the purposes of the United Nations Peacekeeping Operations. This is done in order to see if humanitarian tendencies have been an increasingly cause for the UN to initiate an intervention with military means. This paper uses the time period from the end of the cold war until today, since that historic occurrence increased the U.N.?s involvement in peacekeeping. By using this time span it enables the survey to indicate changes in the mapping of humanitarian interventions.

This essay is included as a sub-study of a survey about child poverty, which the Department of Sociology at Uppsala University, the Ombudsman for Children and Gillbergska Stiftelsen (the Gillberg?s foundation) has been commissioned by Uppsala Town to implement. The intent of this essay is to investigate how three pre-school managers in the municipal preschool in Uppsala describe child poverty, how they see the preschool?s social responsibility and how they manage child poverty in their practical operation. The essay is a qualitative study and informants' responses has been analyzed and related to symbolic interactionism, the thesis theoretical basis.

The use of information technology (IT) is exploding. Today, it is in our daily routines to use some kind of information technology. The increase of users increases the number of cyber crimes, ie, crimes that in some way involve IT. As the cyber crimes grow in numbers, the workload for technical investigator increases, these are called digital crime investigators. The thesis is about how police digital crime investigators work and what problems they may encounter during an investigation.

Under de senaste tio åren så har svensk polis blivit utsatt för ett en rad svårare händelser. En av dessa är t.ex. polismorden i Malexander där två poliser blev skjutna till döds. Dessa händelser har gjort att polisen utvecklat en gemensam nationell bastaktik för att underlätta arbetet i den egna myndigheten och vid gemensamma insatser. År 2004 togs beslutet om att införa en nationell bastaktik för Sveriges poliser.

Stalkning, systematisk förföljelse är ett brott som ökar i Sverige, närmare 150 000 personer utsätts varje år visar Brå (2006) i en undersökning. Stalkningsoffrens tillvaro påverkas kraftigt och många är rädda. En tredjedel av stalkningsoffren anmäler förövaren men det finns brister i handläggningen av stalkningsärenden eftersom de inte prioriteras av rättsväsendet. Okunskap om brottets komplexitet och det lidande som brottsoffren utsätts för är vanligt bland poliser. Ny lagstiftning kommer dock att ge polis och åklagare möjligheter att agera kraftfullt i framtiden.

The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.

In this essay the focus lies on two municipalities, Vellinge and Kristianstad.

Mitt examensarbete behandlar möjligheterna att effektivisera operationsverksamheterna på svenska sjukhus med hjälp av IT lösningar.Information har samlats in genom intervjuer av sjukvårsdspersonal och genom sökning på Internet. Operationsprocessen beskrivs och analyseras med hjälp av värdeanalysmetoden och flaskhalsanalysmetoden.Min slutsats är att svenska sjukhus bör effektivisera sina operationsprocesser i en strävan efter att skapa rätt värde för sina patienter. De bör försöka utnyttja möjligheterna med operationsplaneringssystem för att eliminera onödigt arbete och utveckla patientvärde. De fåtal svenska sjukhus som ännu inte gjort det bör införa operationsplaneringssystem.Det är inte IT system i sig själva som tillför nytta och som effektiviserar verksamheter. Det är den förändring i arbetssätt och processer som kan stimuleras och realiseras med hjälp av IT systemen som tillför nytta.Det räcker inte med att införa IT system och effektivisera arbetssätt för att effektivisera operationsverksamheterna.

Syftet med denna undersökning har varit att genom ett fältarbete i två sjundeklasser få kunskap om undervisning med skönlitteratur har gett elever i den ena klassen andra förutsättningar att skriva en essä än i den andra klassen. Essäuppgiftens uppgift var att fungera som avslutning på arbetsområdet ?Egypten för 5000 år? sedan för eleverna. Jag har valt att genom en enkät undersöka skillnaderna i elevernas upplevelse av arbete med skönlitteratur i historieundervisningen. När det gäller enkäten och essäuppgiften i de båda klasserna skilde sig resultatet av dessa inte nämnvärt från varandra vilket jag hade förväntat mig.

Det ingår ett flertal projekt som ligger under arbetet med ?En Nationell Polis?, och vi har för avsikt att redogöra för två av dem. Det ena är framtagandet av en nationell polistaktik vid vardagsverksamhet ? farlig situation och vid insats mot folkmassa och det andra handlar om en nationell samordning av bombskyddsverksamheten. Vi har för avsikt att redogöra för vad tanken bakom ?En Nationell Polis? är och vad dessa två ovan nämnda projekt innebär.
