Modellering av dagvattennät utgående från markhöjder
Enligt Svenskt Vatten ska dagvattensystem vara dimensionerade för att klara ett regnmed en återkomsttid på 10 år. För att utvärdera om ett system är rätt dimensionerat kanen dagvattenmodell upprättas. Det är då viktigt att veta vilka nivåer ledningarna har mendenna information är bristfällig hos många kommuner. Ledningarna borde dock följatopografin i generella drag och borde därför kunna uppskattas därifrån.Syftet med denna studie var därför att utveckla en metod för hur vattenledningarnasnivåer kunde ansättas på ett enkelt sätt utifrån marknivån och hur stor betydelse detskulle ha vid dagvattenmodellering. Ett ytterligare syfte var att även bedöma Lidingöstads dagvattensystem, där information om ledningarnas nivåer saknades, utifrån dennametod.
MiFID - En analys av direktivet om marknader för finansiella instrument och dess inverkan på kundens ställning på värdepappersmarknaden
This essay aims to analyse the Markets in Financial Instruments Directive, formally called MiFID, andwhether it improves the situation of the investor, the customer, on the market for securities. MiFID isa directive from the European Union and was implemented by the member states in 2007. Besideshaving the objective to harmonise the European financial market, the directive aims to increasecompetition and efficiency among the markets in the member states.After our initial reasearch in the area we choosed to do a textual analysis and divide the content ofMiFID into three main areas: trading venues, transparency and investor protection. These areas aresubsequently analysed in relation to the investor?s situation on the market for financial securities andthe overall question at issue is whether MiFID improves the situation of the investor.
Virtuell hållfasthetsprovning av en turistbuss
The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.
Modellering av ett bränslesystem i Modelica : tillämpat på ett obemannat flygplan
Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.
Ingenjörpluton : Kung på en sak eller klåpare på tusen?
This essay is about the engineer platoon. The engineer platoon has many different tasks and from my own experience sometimes too many. The platoon is able to build bridges, clear mines and to perform all kinds of construction work in rural or in urban terrain.In this case study I compare goals/demands for the battalion to goal?s set up for the company and finally what effects this has on the engineer platoons abilities. The main question is, if the engineer platoon really can solve all tasks given to them in the document TOEM? Abilities such as effect, protection and movement are the bearing parts of the case study.The materials I have analyzed are mostly from documents published by The Swedish Armed Forces.
Belåning av aktier : har riskerna underskattats?
Investors? use borrowing as a way to profit from leverage advantages in their portfolios.When investors borrow with their securities as safety for the loan and the value of thesecurities decrease the investor can get a portfolio with more credit than what is covered bythe value of the securities and risk huge losses. To what extent an investor is allowed toborrow with his portfolio as safety depends on the bank or broker and varies between theproviders. By studying available material and in addition to that making an empirical study Iattempt to find out the reason for the varying degrees of leverage possibilities between thebrokers and how the degree of maximum borrowing on the securities are decided. Thefindings show that decision of leverage degree on a security is made after first making aquantitative analysis of the stocks volatility and liquidity and thereafter make a qualitativeanalysis of the company.
LMSim, cacheminnessimulator för utbildningssyfte
Cache simulator is a tool to increase the understanding of a cache memory. Therefore cache memory simulation is included in the course Computer Engineering IS1200 at the Royal Institution of Technology. The purpose of this project is to develop a cache memory simulator for education. The existing MipsIt and Mips Simulator which is currently used in IS1200 has been the main source of inspiration. This resulted in the development of the cache memory simulator LMSim.

The aim of this study was to examine the amounts of heavy metals in the sediment of a wetland constructed for stormwater treatment. The wetland is called Vattenparken and is located in the city of Enköping. The heavy metals which were analysed were Pb, Cd, Ni, Zn, Cu, Cr and Hg. The total metal concentrations were determined using HNO3 chemical extraction. From 8 sampling sites 5 sediment cores were taken.
Gynnar Sverige missbruk av visstidsanställning?
In the European Union and in Swedish labor law, permanent employment is the main goal for employment of workers. An exception to that rule is temporary employment. The Swedish rules relating to temporary employment have undergone several changes since the Employment Protection Act was implemented in 1974. The last reform in 2007 has received criticism by respondents for not following the Union directive on fixed-term work, which went into effect in 2001. In 2010 the European Commission opened an infringement case against Sweden, after a complaint from a Swedish employees? organization.
Mänsklig påverkan på mindre vattendrag i skogslandskapet : en inventering av vägtrummor och skyddszoner kring dessa i Uppsala län och norra Västmanlands län
Interference in an ecosystem means a disturbance. When harvesting, forest roads have to be
build to cope with heavy duty vehicles. Crossing brooks can not always be avoided. In this
case bridges or culverts have to be built. There are many different kinds of culverts and
depending on what type you choose and how you place the culvert, the watercourse and the
water organisms can be harmed in different ways.
Konstruktioner av kvinnligt och manligt i våldtäktsdomar : En kvalitativ textanalys
The purpose of this study is to examine constructions of plaintiff [woman] and the defendant [man] in Swedish rape convictions from 2013. The cases in this study cover acquaintance rape. We also intend to analyze the constructions of the sexes in relations to each other. The study is completed by a qualitative text analysis, with inspiration of a hermeneutic interpretation. The result is presented by four categories: the worthy of protection of the woman, the penalty of the man, the complicity of the woman and credibility.
"...som ett trappräcke i en brant, brant trappa" : En religionspsykologisk studie av riter och kultur i copingprocesser hos drabbade av tsunamikatastrofen i Thailand 2004
Coping theory asks what the cognitive and behavioral patterns of individuals dealing with stress are. This essay includes, besides the perspective of the psychology of religion, theories of culture and ritual in exploring two Swedes coping with the natural disaster in Thailand year 2004. The vacation paradise was struck by an enormous flood wave, called a tsunami, causing vast destruction and the death of over 200.000 people. Among these 543 were Swedes on vacation. When a disaster of such measures happens, what kind of stress does it cause? How do you cope? Are religion and ritual important? What is the function of the culture in the copingprocess? Using hermeneutical analysis this essay interprets the material from two books by Swedes, who not only experienced the disaster, but lost two children and husband and wife in the flood wave.
