In order to avoid harmful substances ending up at the municipal sewage treatment plants, it is important to purify the wastewater at the source. One such source is the wheel washers available in many tire garages which are used to wash the wheels on our vehicles when we change between summer and winter tires. It is important to wash the wheels before storage, to extend the tires lifetime. The purpose of this study is to find a green innovative solution for reduction of emissions of heavy metals at the source, so that the sludge from the sewage treatment plants can be used as fertilizer. The target is to find a wheel wash method which leads to compliance with the guidelines for car washers, and that also provides a better washing result than with the existing method.

Trots att självkänsla är ett frekvent studerat ämne saknas en allmänt erkänd teori och definition som kan utgöra en grund då självkänsla studeras. Gemensamt för flertalet teorier är att självkänslan grundläggs i barndomen samt att självkänsla rör en persons uppfattning om sig själv och personens omdöme om hur han eller hon uppfattas av omvärlden. Studiens syfte var att göra en psykometrisk utvärdering av en modifierad version av Jag tycker jag är samt att studera formulärets test-retest reliabilitet. Jag tycker jag är utvärderades genom att analyseras tillsammans med andra välprövade självkänsloskalor. Undersökningsdeltagare var 100 psykologistuderande (M = 28.4 år; s = 7.3 år).

This thesis has been carried out in autumn 2009 at Uppsala University for Boliden Mineral AB. Physical modelling has been used to model a comminution circuit. The model has then been linked to a PLC.When a concentrator is about to become operational Boliden Mineral AB have been looking for a way to test the PLC. The purpose of this report has therefore been to develop models for the subprocess in a concentrator and link these models to the PLC. The subprocess was a comminution circuit in Aitik36.

SammanfattningSyfte och frågeställningar: Syfte var att a) undersöka interbedömarreliabiliteten av testerna Neer sign (NS), Hawkins-Kennedy test (HKT) och Jobe test (JT), samt b) undersöka sambandet mellan resultatet vid NS, HKT och JT med resultatet vid muskuloskeletal ultraljudsundersökning hos patienter med subacromial smärta. Frågeställningarna var följande: Hur är interbedömarreliabiliteten för NS, HKT och JT? Vilken sensitivitet och specificitet har NS, HKT och JT som enskilda test respektive tillsammans i ett testbatteri för att diagnosticera subacromial smärta med muskuloskeletalt ultraljud som referensmetod? Hur väl samvarierar ett positivt impingementtest med ett onormalt lågt avstånd mellan humerus och acromion? Finns det någon skillnad av det acromiohumerala utrymmet (AHD) mellan personer med eller utan impingement i skuldran? Metod: 18 forskningspersoner (fp) med skulderbesvär (medelålder 54 år, besvärsduration median 2,25 mån) rekryterades konsekutivt.  Under samma dag undersöktes fp av två sjukgymnaster med testerna NS, HKT och JT. Ultraljudsundersökning utfördes inom åtta dagar och användes som referensmetod vid uträkning av sensitivitet och specificitet för de kliniska testerna.

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).

A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.

The purpose of this thesis is to evaluate the combination of bibliographic coupling and three hierarchical cluster analytic techniques: average, complete and single linkage. Bibliographic coupling is applied as a measure of similarity between recently published articles and the cluster techniques are used for the partition of a set of articles into subsets of articles with similar research focus. The field of information science is applied as the test arena and the selection of data, i.e., the article population to be partitioned, is based on a number of central journals. Methods of evaluation include both quantitative approaches as well as a qualitative one. For comparing the resulting partitions, adjusted Rand index is utilized and for the establishment of cluster coherence and isolation, measures of average normalized coupling strength is applied.

Development and accuracy tests of advanced exchange trading systems require well adjusted tools for testing. Aptness of these tools are probable to have a major impact on identification of bugs and verification of new functionality. Identifying erroneous parts and bottlenecks of the trading system is of outmost importance for the exchange as a whole since stability and correctness are two of the determinant factors its viability is measured by. This paper covers how this test-tool was created and the motivation behind the design choices made. The tool was created with the goal to be broad enough to cover the majority of cases that could arise, fast enough to be able to test the trading systems speed limitations (i.e.

What is the?self? and to become ?one-self?? To resolve this questions possibility I´ve been using the philosopher Søren Kierkegaard metaphysic paradoxes. This essay about the ?self? shows the reader the difference between describing a transcendent and immanent phenomenon and if it´s possible to become or to not become ourselves. The process is a key of the ?self? which Kierkegaard explains the ?self? in and for it-self.

The project has sprung out of my imagination. I wanted to find out what happened to my creativity, and my way of making product design if I used the method of putting myself into a fictive world. The project has taught me to rely on myself and my knowledge as a designer.I have made a chair which closes out sounds and gestures in public places. A chair which provides you with peace and quiet in a busy environment..

The goal of this thesis is to analyse whether the method ?Observiaire? is of any use for traffic analysis. The method consists of analysing film material, preferably before and after changes are made to an area, by answering a survey for the users that are observed within the population. The method also opens up for deeper qualitative analyses which are rooted in the quantitative data collected from the survey-study. In this study we analyse the method by applying it to the case study of the changes made at Götgatan in Stockholm, where a green wave was implemented and the bicycle road widened.

Very often the interesting variables are explained by several underlying variables and in statistical analyses it is common to study the relationship between variables and groups of variables. Because of this multivariate analysis is commonly used in both science and industry. There are two problem with both univariate and multivariate analyses. One is when the variables are correlated. The other is when the number variables of exceeds the number of observations which makes the matrices algebra used in the analysis impossible to execute.
