Undersökning av modulationsscheman för existerande bredbandsteknologier

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

Lillån : Statusbedömning enligt EU:s ramdirektiv för vatten

In Sweden, the County Administration board is responsible for improving the water quality in lakes and watercourses according to the European Union Water Framework Directive. In Västmanland county, where river Lillån is situated, the County Administration of Västmanland have the main responsibility for the aquatic environment in that area. The knowledge about the different watercourses in the chatchment of river Lillån is today limited. The aim with this study was to evaluate the ecological quality of River Lillån based on water chemistry analyses and benthic fauna investigations. The aim was also for the benthic fauna to compere different samplingsites and sampling methods with each other in order to see how the species composition changes in the river, and to see the advantages and disadvantages with different sampling tecniques.

Livskvalitet hos patienter opererade för lungcancer- upplevelser av livskvalitet och samband mellan HRQoL och vårdupplevelse.

SAMMANFATTNING Introduktion I västra Sverige utfördes år 2010 cirka 200 lungoperationer på patienter med lungcancer. I Sverige är lungcancer den femte vanligaste cancerdiagnosen. Globalt kommer antalet fall att öka inom en 20-årsperiod enligt WHO:s bedömning. Tidigare studier visar att denna patientkategori upplever en sämre livskvalitet. Denna uppsats behandlar ämnet livskvalitet och om man med bekräftande omvårdnad kan öka patienternas känsla av livskvalitet.Syfte Syftet med denna undersökning var att belysa hur patienter med lungcancer uppfattar sin livskvalitet i samband med thoracotomi vid mätning under 1 år, och om det finns någon relation mellan det bekräftande mötet med vårdpersonal och hälsorelaterad livskvalitet.Metod En kvantitativ ansats användes för att mäta upplevelsen av livskvalitet samt hur informanterna uppfattade mötet med personalen på vårdavdelningen.

HAVECA-modellen : En metod för att fortlöpande säkra ett internt nätverk mot tredjepart

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

VÄGTRAFIKBULLRETS INVERKAN PÅ UTFORMNINGEN AV BOSTADSBYGGNADER I STADSMILJÖ

The public interest in central living in today?s cities has led to an increasing effect of traffic noise pollution, and today 20% of the inhabitants in Sweden suffer from noise a level that exceeds the limits. At the same time the traffic keeps increasing, and recent researches shows that traffic noise pollution and several of today?s most common health issues are connected, for example, reduction of performance, sleeping issues and cardiovascular diseases. For this cause rules, guidelines and environmental goals has been developed, as well as software?s which calculates the levels of pollution, all this to investigate and improve the environment.

Utvärdering av Transportstyrelsens flygtrafiksmodeller

The Swedish Transport Agency has for a long time collected data on a monthly basis for different variables that are used to make predictions, short projections as well as longer projections. They have used SAS for producing statistical models in air transport. The model with the largest value of coefficient of determination is the method that has been used for a long time. The Swedish Transport Agency felt it was time for an evaluation of their models and methods of how projections is estimated, they would also explore the possibilities to use different, completely new models for forecasting air travel. This Bachelor thesis examines how the Holt-Winters method does compare with SARIMA, error terms such as RMSE, MAPE, R2, AIC and BIC  will be compared between the methods. The results which have been produced showing that there may be a risk that the Holt-Winters models adepts a bit too well in a few variables in which Holt-Winters method has been adapted.

Projektet Läskonster : En uppföljning av ett lässtimulerande projekt

The purpose of this study is to carry out a follow-up study of the reading stimulating project Arts in Reading. The project was in progress between the years 2007 to 2009 in Sweden and nearly 80 librarians from 57 public libraries participated. The aim of the project was to initiate new methods fot how to stimulate reading for children. The promoters of the project wanted to initiate the use of new art forms in the work for reading promotion, encourage more collaboration with new actors in the culture area, and co-operate more with the children.The aim of the present study is to investigate to which extent Arts in Reading really succeeded in establishing its goals, whether new methods were brought about, and how this work was done. Another aim is to find out how librarians in public libraries work to develop children's reading.The theoretical framework is based on Ragnhild Söderbergh's term inculturation, Elisabeth Björklund's research on how children acquire literacy, and Lev S.

Operationssjuksköterskors upplevelser av patientkontakt : - En kvalitativ intervjustudie

Bakgrund: En viktig del i att jobba som sjuksköterska är att kunna förse patienter med god omvårdnad. Att jobba i en operationssal innebär att jobba enligt ett tidsschema där de olika yrkesgrupperna ofta jobbar parallellt med varandra för att uppnå hög effektivitet. Operationssjuksköterskor ansvarar för hygien och sterilitet under operation och mötet med en vaken patient blir ofta kort och intensivt. Man arbetar med en patient i gången vilket möjliggör ett personcentrerat vårdande. Syfte: syftet med studien var att beskriva operationssjuksköterskors upplevelser av patientkontakt.

Effekten av att använda tryckavlastande hjälpmedel intraoperativt på uppkomsten av trycksår : En experimentell studie

Svenska studier visar att utförandet av trycksårsprevention har låg prioritet bland sjuksköterskor samt att sjuksköterskor även har undermåliga kunskaper om uppkomst och riskfaktorer för trycksår. Uppkomna trycksår orsakar stort lidande för patienten och höga kostnader för samhället. Den farligaste riskfaktorn för att få trycksår är immobilitet. Under en operation kan patienten inte känna obehag eller ändra sitt kroppsläge på grund av erhållen anestesi och/ eller bedövning. En operation utgör därför en högriskfaktor när det gäller uppkomst av trycksår.Syftet med studien var att undersöka effekten av att använda ett tryckavlastande hjälpmedel på patienter med operationstid på 90 minuter eller längre för att förhindra uppkomsten av trycksår.En experimentell studie med ett konsekutivt urval av 89 medverkande genomfördes på en operationsavdelning i Mellansverige.

Att ämnesbestämma bilder: En teoretisk undersökning

The aim of this master ´s thesis is to understand why there are difficulties in finding joint methods and standards in the field of image indexing. The main focus for interpreting these issues is on Sara Shatford ´s article Analyzing the Subject of a Picture: A Theoretical Approach. In the article Shatford discusses a theoretical basis for identifying and classifying the subject in a picture. In doing so she uses concepts taken from The Philosophy of Art, Meaning in Language and Visual Perception. With the aid of S.R.

Bastu-frigidarium,energieffektivt system för återhämtning

Sweden is considered to have one of the world's highest animal welfare standards in agriculture. Despite this, there are shortcomings in animal husbandry. One example is overcrowding, which is a way to increase stock size without making costly investments in the buildings. It can be carried out systematically to increase profitability or due to, for example uneven calving during the year. The European Commission criticizes the fact that stocking density is not controlled under Swedish welfare inspections.

Integrering av estetiska uttrycksformer i kärnämnen matematik och modersmål : En jämförande studie av en svensk och en rysk lärare

The aim of my examination work was to compare and research how russian respective swedish teachers make use of educational aesthetic methods such as drawing, drama, music and dance in the teaching of core school subjects ? mathematics and swedish respective russian languages. The aim of this work was to find out which of these methods are used by pedagogues in the process of education and on what level are they integrated into the theoretical pedagogic work. The point was to also analyse the regulation documents used as pedagogical base in schools i've been doing my survey in. This was done to partly find out what arts perspective is given in the curriculum and partly to see what pieces of it are reflected in the process of education.

The aim of the essay is to explore the foundations and methodology of the program, how the methods of the program are put into practice and how these methods compare to what current research findings claim to be effective factors in successful interventions.

Produktivitet i robotcell

The report describes the process of identifying the interference that exists in a newly installed automated robotic cell and suggest improvements to increase productivity. The cell is used for lifting up extruded aluminum sections onto a conveyor which deliver the material to a anodising line at a company that manufactures aluminum extrusions.To find the areas with the best possibility for improvements in the cell we used a variety of job measurements e.g. measure of standard times for each operation in the cell. The core of the report is a study of the robots.One reason for this study is that the robots do not reach the productivity they were purchased to. The main cause not reaching the productivity is the visionsystem.
