For the past three to four years, Ghana has experienced an energy crisis which has resulted in frequent power outages. Although water levels in the main Akosombo dam has been low, electricity generation from hydro has not declined but steadily increasing pointing to efficiency in generation. However inefficiencies in grid transmission coupled with decline in thermal generation of electricity from

Syftet med studien är att belysa körledares syn på olika sångtekniska frågor i kör, och vad de menar krävs för att kunna sjunga så bra som möjligt i kör. För att uppnå syftet med studien är den gjord genom metoderna enkät och kvalitativ intervju med tre körledare. Studien visar att körledarna ser sångtekniken som en grund dels för att körsångarnas röster ska må så bra som möjligt, men också för atThe purpose of this study is to shed light upon choral conductors’ views of various singing technical issues in choir singing, and what they mean is necessary to be able to sing as well as possible in a choir. For this purpose, the study has been performed using a poll as well as through qualitative interviews with three choral conductors. The study shows that choral conductors see singing techni

The financial crisis of 2007 and the subsequent global recession have caused stakeholders, governments and the public to criticise the amorality of the financial sector. For banks, being in the center of critique, corporate social responsibility (CSR) is argued as a promising concept to regain legitimacy. Despite broad engagements highlighting responsibility, distrust towards banks still remains h

Uppsatsen presenterar satsförkortningen genitivus absolutus och beskriver hur den används i Lukasevangeliet. Användningen jämförs med grammatikornas beskrivning av genitivus absolutus. En kortare sammanfattning av bruket i Markusevangeliet ingår.

The Victim Support organization is a Swedish non-profit organization that provides support to victims of crime. The organization relies on its volunteers sinse they are the ones who perform the majority of the work in the various offices. For the organizations work to continue as it does today a requirement is that the number of volunteers is reasonably stable. As the number of organizations in ne

The action to buy sexual services has been criminalized in Sweden since 1999. Previous researches have found that the action for a long time has been defined as a social problem in Sweden. The people providing these services have rarely been asked to share their opinion on these matters in surveys and official reports. Our experience from our education in social work is that the importance of list

Syftet med vår studie var att belysa ensamkommande flyktingbarnens retrospektiva erfarenheter av sin tid i HVB-hem, med fokus på hur de upplevde sin vardag, vilka faktorer de ansåg vara av betydelse för att hantera sin vardag och hur delaktighet och omgivning påverkade deras vardag. Vår empiri har samlats in genom kvalitativa intervjuer med sju tidigare ensamkommande flyktingbarn. Vi analyserade iThe aim of our study was to highlight the unaccompanied refugee children’s retrospective experiences of their time in HVB-homes; focus being on how they perceived everyday life, which factors they considered to be the most important in dealing with everyday life and how participation and environment affected their everyday life. The data was gathered by qualitative interviews with seven previously

We present a multifactor model of the affine term structure of interest rates with dynamics of macroeconomic factors following the diffusion process in the Vasicek model. Using observable series, we investigate the goodness of fit of the model and the impact of the variables on bond yields. We describe in detail the derivation of the model and the numerical techniques for estimating it. We find th

Skelettskintigrafi är en bildgivande undersökning liknande röntgen, där cancer metastaser och andra benskador visar sig som hotspots. Att identifiera dessa hotspots är en svår uppgift även för erfarna läkare. I detta arbete används faltningsbaserade neuronnät till att träna datorer att hjälpa läkare identifiera hotspots.The main goal of this thesis is to design and implement a convolutional neural network (CNN) to classify whether hotspots in bone scintigraphy images represent cancer metastases, caused by prostate cancer, or some other physiological process. A side task was included, where another CNN was designed and trained to classify whether a bone scintigraphy image image is acquired from the front of the pa

The failing firm defence is a tool that an antitrust authority can use to approve a merger that usually would have been blocked if one of the merging firms is failing. The defence has during the last years been used a number of times on EU level as well as in Sweden. This thesis explains how the Cournot model can be used to analyse the failing firm defence. It also presents and discuss’ literature

With today's sustainability thinking and environmental awareness, it is more important than ever to customize even our railway, with its components, for tomorrow's needs. An investment in the replacement of light source is not only an environmental and economic benefit, but also a win for the maintenance. We have chosen in this thesis to investigate why LED technology is not yet incorporat

The part of a structure which separates two floors is called a slab. A type of concrete slab that is becoming increasingly popular is hollow core slabs. A hollow core slab consists of slabs of 1,2 m width placed next to each other, and the space that is created between the slabs is filled with concrete after mounting. The hollow core slab transfers horizontal forces, such as wind load and earth pr

Member State financing of public broadcasters has long been a contentious issue within the European Union, which strives for an open marketplace where broadcasters of different origins move and compete freely. The public financing of certain broadcasters – reinforced by the Amsterdam Protocol and Member States’ desire to maintain and enhance democracy as well as social and cultural values – poses

Uppsatsen syfte är att undersöka hur en lokal Röda Korset krets kan organisera sig och samverka med andra organisationer i ett postmodernt samhälle samt undersöka hur de frivilliga i denna krets upplever sitt engagemang och vilken betydelse det har för dem i ett postmodernt samhälle. Studien är gjord med en kvalitativ forskningansats och empirin består av intervjuer med fyra frivilliga i kretsen s

In January 2015 the Swedish police force went through the most comprehensive restructure of the organization since it became a public authority in 1965. In connection with the refugee crisis in Europe that culminated in the fall of 2015, the Swedish government decided on the implementation of a law that Sweden would establish a border control. Therefore during the massive restructure, the border c

The Republic of Rwanda has traditionally been a home to three ethnic groups: Hutus, Tutsis and Twas. Clear divides between the groups have been created over the centuries by both inside and outside forces. Each group shares among themselves a collective identity which can be used to rally masses to create tensions in society. This is a development a stability-pursuing state seeks to avoid. In the

Energioptimering utav Ericssons radio NGR Micro G1 Sedan lång tid tillbaka har mänskligheten belastat vårt klimat och ekosystem. Idag känner vi till konsekvenserna av vårt leverne och runt om i världen skrider regeringar och organisationer till verken och styr om vårt samhälle mot en mer hållbar framtid. Man söker ständigt nya lösningar som förbättrar och minskar energikonsumtionen och utsläppen fRigorous studies have been conducted on Ericsson's NGR Micro G1 B2/B25 radio. The radio's part in the telecommunications chain and components within the radio have been determined and mapped according to certain characteristics giving an understanding of their function. The obtained knowledge has been applied in order to make the operation of the radio more energy efficient. This has been
