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).

During test flights SAAB uses the data acquisition system COMET 16. The part of the system that receives the signals from the sensors and converts them is called KSM 15. The purpose of this thesis is to develop a data acquisition module on stacked PC/104 modules with a lower production cost. Our work has been divided into one part about analog signal conditioning and a second part with digital filtering and memory management of the sampled data. The analog part, designed of regular components like instrument amplifiers, voltage references, operational amplifiers and multiplexers, adjusts the sensors signal levels for the ADC?s that converts the signals.

Stump treatment today requires large quantities of clean water mixed with the protective product Rotstop, to fully cover the stump surface. In order to reduce the water consumption without reducing the coverage of the stump surface, the pressure in the stump treatment device can be increased. Therefore, the Phlebiopsis gigantea (Fr.) Jül. suspension used as a biological control agent to prevent Heterobasidion annosum (Fr.) Bref. infection was pressure-tested.

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). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..

Title:?Varför går man inte hårdare fram? ? En studie i krigsorienterad journalistik av Public Service från Ukrainakonflikten?Authors:Cemil Arikan, Staffan Florén Sandberg and Karl Henrik OlssonSubject:Undergraduate research paper in journalism studies, Dept. of journalism, media and communication (JMG) Gothenburg UniversityTerm:Spring 2014Supervisor:Mathias Färdigh, JMG, Gothenburg UniversityPages/words:48 pages/16701 wordsPurpose:The main purpose of the paper was to examine if and to what extent the conflict coverage of two Swedish public service news programmes from the ongoing Ukrainian conflict could be said to orientate towards either war or peace journalism.Method:Quantitative and qualitative content analysisProcedure:News broadcasts from Rapport 19:30 and Dagens Eko kvart-i-fem, covering the Ukrainian conflict, over a period of two months, were analyzed from the normative perspective of Johan Galtung?s peace journalism theory and Wilhelm Kempf?s theory of war and peace discourse.Results:Both Rapport and Dagens Eko were found orientating towards war journalism. Reports were given, in a great extent, to events of violence and verbal threats.

In today?s society climate change has grown to one of the largest global issues. To reduce emissions of greenhouse gases, large changes of the energy system are required. An increasingly popular solution is investments in local production of renewable energy resources like wind, solar or geothermal power. The following report examines the possibility for implementing a solar power plant on the new hospital Nya Karolinska Solna. Two different technologies for extraction of solar energy has been studied, solar thermal collectors  to meet the need of heating and solar cells to satisfy the need for electricity linked to operating the hospital building.

Authors: Philip Trollér & Jasmin FrljevicTitle: A sharp striker or forwardLevel: Bachelor of JournalismLocation: University of GothenburgLanguage: SwedishNumber of pages: 62All throughout time the Swedish language has been influenced by various external languages. And throughout the years many loanwords have been introduced to the Swedish vocabulary. And this phenomenon occurs in the texts written by Swedish sport journalists. But in what extent do loanwords from the English vocabulary occur in texts written by Swedish sportjournalists, in what types of texts they can be found. And also why the usage of loanwords occur.The purpose of our study is to find out how frequent English loanwords are in Swedish sports journalism.

In the next few years the pollutants loading at the Slottshagen wastewater treatment plant in Norrköping is going to increase due to the reason that one of the waste water treatment plant in the district will be shut down.A survey of how these different pollutants are divided in the treatment process is therefore necessary for mapping out both the loading and treatment efficiency.This can be achieved by studying mass balances.Mass balances were carried out for the water treatment process for the mechanical/chemical,biological and the chemical stage.The mass balance studies show that the treatment efficiency was very good. However in order for the mass balances to be quite consistent and to ensure complete coverage of results and conclusions i.e. more reliable results, sludge samples should be collected and taken at different times per day and the influent rate should be investigated.In this work mass balance has been set up in order to illustrate and identify the factors that should be considered and taken care of for further estimation using mass balances in the future. Furthermore this survey results in a calculating model for the mass balances at thisplant.This calculating model is used as a tool to facilitate future calculations for mass balances for the water treatment process at Slottshagens wastewater treatment plant.Moreover it provides a basis for carrying out further estimation of the treatment process in the near future.In this project the importance of some operating parameters was also taken in consideration.This calculating model can be modified so that calculations of such operating parameters i.e. sludge loading and sludge age can be easily performed.Such information can be used further to evaluate different operation alternative in order to ensure an optimal use of the treatment process with in the plant..

Syftet med denna studie är att studera mediernas rapportering kring ett antal specifika händelser kopplade till SOS Alarm. Med vår undersökning avser vi att bidra till kunskapen om hur tidningarna Aftonbladet och Dagens Nyheter framställer SOS Alarm i sina nyhetspubliceringar. Mediernas rapportering är viktig att studera då mediebilden av SOS Alarm kan påverka allmänhetens förtroende för denna viktiga samhällsaktör. Detta är viktigt på grund av att den bild och på det vis som medierna framställer olika händelser påverkar människor, vår sociala och kulturella kontext, att se och uppfatta verkligheten vi lever i. Medierna utgör ett kraftfullt verktyg för människors åsikter, värderingar och påverkar människors beteende.Studien har använt sig av kvalitativ textanalys och inriktat sig på 43 tidningsartiklar från Aftonbladet och Dagens Nyheter.

This study explores whether environmental, social and governance (ESG) issues affect the monetary value of a company.The samples used in this study have been taken from the Johannesburg Stock Exchange (JSE) in South Africa. Since 2010, JSE have been categorizing companies using the King Code III criteria to establish a Socially Responsible Investment index (SRI index). Companies that fulfill the required number of criteria are classified as 'best performers' using the SRI index.  In this study the monetary value of a random sample of 'best performers' has been compared to the monetary value of a random sample of companies without an SRI index evaluation.This study found that companies without a SRI index have a higher unique risk, which means a lower stock price with a higher dividend yield. Companies with an SRI index evaluation have a lower unique risk, which means a higher stock price and lower dividend yield. In conclusion, this study shows that SRI adjusted companies have an enhanced monetary value in comparison to non- SRI adjusted companies..

The aim of this issue is to study how Swedish public libraries deal with the principles of freedom of speech and freedom of information in connection with public use of the Internet. The authors intention has been to find out whether the public use of the Internet has caused ethical problems for library workers and how the libraries solve situations when they consider their principles violated by library users. The authors study the debate on the issue in a couple of Swedish library magazines published during the late 1990s and they also give a few examples from the USA during the same period. They study the ethical principles and directives for schools published by the Swedish Board of Education as they claim that many of the public library users are students who bring along their ethical conceptions and thereby affect the ethical climate of the libraries. In their study the authors refer to ethical rules given to librarians by their trade union DIK and to the conclusions drawn from the hearing Good Ethics on the Net held by the Swedish IT Commission in 1998.

Detta arbete är ett examensarbete i matematik på kandidatnivå vid Växjö universitet. Det är en studie av kodningsteori i allmänhet med fokusering på cykliska koder och Reed-Solomon-koder i synnerhet. Reed-Solomon-koderna används för att skapa McElieces kryptosystem. En kortfattad analys av McElieces kryptosystems säkerhet görs tillsammans med en genomgång av kända sätt att forcera denna typ av kryptosystem. Här visar det sig att användning av Reed-Solomon-kod försvagar kryptosystemet i förhållande till om den ursprungligt föreslagna Goppa-koden används.

Ett införande av ett informationsystem i en organisation lederofta till förändringar både på ett organisatoriskt och individuelltplan. Exempelvis kan individer få andra arbetsuppgifter eller blirutan arbete till följd av informationssystemet.Informationssystem kan också användas inom säkerhetskritiskaområden som exemplevis inom sjukvården, flygplansindustrinoch inom det militära. Vem bär ansvaret vid felaktigheter isystemet då olyckan är framme? Vid en överblick över erkändasystemutvecklingsmetoder återfinns ingen vägledning hur deetiska aspekterna ska beaktas i samband med systemutveckling.Syftet med uppsatsen var att svara på frågan hur det tas hänsyntill de etiska dilemman som kan uppstå i samband medsystemutveckling. För att besvara frågan utfördes femkvalitativa semistrukturerade intervjuer med systemutvecklaremed olika arbetserfarenheter.

In Montessori pre-schools early reading and writing is an important feature. By tracing sandpaper letters with their fingers and voicing the sound simultaneously the children connect phonemes to graphemes and normally learn to write between the ages of four and five. 24 sixyear old children who attended Montessori pre-school and 26 six-year old children who had not attended Montessori school were assessed with a test assessing their linguistic awareness.The result showed that the Montessori children were more linguistically aware than the children who hadn?t received any literacy training. The scores of the Montessori children were highest on phonological awareness.

On subsequent days, the 18th and 19th of December 2012, large groups of young people gathered to protest in the centre of Gothenburg. The gatherings mainly occurred outside two high schools: Plusgymnasiet and Framtidsgymnasiet. The reason behind the gathering has often been explained by the young people?s reaction to an Instagram account, on which offensive pictures and comments of and about young boys and girls had been published. As a reaction to the protest, police force including helicopters and mounted police, was sent to the streets.
