Utvärdering och uppdatering av typkurvor
The purpose of this thesis is to evaluate and update load curves for Fortum Distribution AB. Theload curve method is a tool used to forecast the strain of an electric grid. The method is based oncustomer annual energy consumption, outdoors temperature as well as customer category. Theload curve method was established by Svenska Elverksföreningen at the start of the nineties andfocus was put on standardizing annual energyconsumption, in order to make the method usableacross the nation. Present consumption patterns have changed since the original load curves wereproduced, which leads to a need to update the load curves.The work began with an update of present load curves according to recommendation taken fromanother earlier thesis.
Utvärdering och åtgärdsförslag av energianvändning i kontorsbyggnad
AbstractEmbla 5 is an office building which has done a large improvement. The clients of this building has made an order of WSP and the student Anders Kempe to calculate the use of energy for the building, and after that result proposing further measures which can decrease the energy use of Embla 5.The ground for this report is when calculation of the present energy use of the building is stated. To make that information of a number of parameters such as envelope, the heating system and ventilation has been located and set in to the simulation program IDA ICE which calculate the energy use.To improve the energy use further this project has been concentrated to change the system of ventilation. Today the ventilation system is of the kind CAV (constant air volume) and the air flow is dimensioned for after recommendations from BBR and Arbetsmiljöverket in the office spaces. Consider that Embla 5 is an office building where the people only staying for 8-10 hours/day so was the ide to see how much energy saving if the air flow is reduced the time people not being in the building.
Nedskrivning av goodwill i svenska storbanker
Background: Sweden and the rest of the world went through the biggest financial crisis at the end of 2008 since the 1930s. The major Swedish banks have goodwill related to their acquisitions inside and outside Scandinavia. Swedbank, SEB and Nordea has acquired in the Baltic countries and Russia, however Handelsbanken has established itself in Great Britain. The crisis in the Baltic countries led that real wages fell, unemployment rose, real estate prices collapsed and the number of borrowers who had trouble repaying their loans increased rapidly. All this led to the problem of impairment of goodwill in the Swedish banks that had expanded rapidly in the Baltic countries.Aim: The aim of this study is to investigate the application of IFRS 3 in Swedish banks before, during and after the financial crisis, and to investigate the low-downs in the four majorSwedish banks in 2006-2010.Completion: The study is primarily based on the case studies by the examination of the annual reports from all banks as well as evaluation of the interviews.The authors have chosen to makea strategic choice of a small number of cases through the concentration on the impairment of goodwill in the bank sector of Sweden.Results: The result of this study is that there are problems for banks in implementation of IFRS 3 in practice because of insufficient information in the banks' financial statements.Generous estimates used in the calculation of impairment testing.
Cito Systems ? Mjukvara i form av ett stödsystem för restaurangbranschen
Stockholm city has recently raised its ambitions for bicycle traffic, the goal is to achieve a larger andsafer bicycle traffic. But cyclists are more vulnerable on the roads than other vehicle users because of the lack of protection. This means that a large proportion of road safety for cyclists is based on the design of the traffic environment. Since most serious bicycle accidents are those that occur in conflict with motor vehicles, and the majority of these accidents occur at intersections, these areas are of great importance forcyclist?s safety.The purpose of this paper is to highlight bicycle accidents at intersections and to suggest improvements in three accident-prone junctions in Stockholm. This is achieved by the study of accident statistics, literature and finally three case studies.The literature study focused on cyclists, traffic safety and traffic safety measures.
Pricing Credit Default Index Swaptions A numerical evaluation of pricing models
This study examines the background and nature of the credit default index swaption (CDIS) and presentsrelevant methods for modelling credit risk. A CDIS is a credit derivative contract that gives the buyerright to enter into a credit default index swap (CDS index) contract at a given point in time. ACDS index, in turn, is a multi-name credit default swap (CDS). Within the eld of research, thisthesis identi es the CDIS pricing models presented by Jackson (2005), Rutkowski & Armstrong (2009)and Morini & Brigo (2011) as the most recognized and developed. These models are evaluated byreconstruction in a numerical software environment.
Undersökning av ljudnivåer på skolgårdar : - samt hur fasad och fönster dimensioneras med uppmätta värden
This report is written on commission by WSP Acoustics. The report studies the outdoor sound levels on school yards in Stockholm. The questions given by the company to be answered was what are the actual sound levels at diffrent school yards with low traffic noise and how can you construct a facade element that reduces the sound level from the outside and meet the indoor requirements. Mesurements for four hours was done at eight schools set north and south of the city centre. The measurement period included one school break and one lunch break.

Juniorfinansiering i fastighetsbranschen? Fokus kring Mezzanine
Real estate financing is one of the key figures for financial success and fundamental to asuccessful business. Funding will come in several different ways, from existing cashflows andassets to new capital requirements which are aimed at different markets.These markets are constantly changing and since the recent financial crisis, there have beenadjustments and austerity measures which led to that the banks have become more restrictive intheir lending.The real estate industry is characterized by both long-term and short-term thinking that ischaracterized by a solid continuity. Our thesis discuss how the demand is in the real estatebusiness and how mature the Swedish market is for junior financingwith focus aroundmezzanine debt and where are we headed in the near future.We've reached out to the key players in the industry on both the buy and sell side of real estatefinancing but also people between lenders and borrowers that handles transaction advice. Tohave been able to implement the analysisa survey and simulation of an investment calculationwas created. This questionnaire was answered by many real estate companies with senior peoplethat had operational positionsmost associated with corporate commitments.
Analys av nyckeltal på produktionskostnader i tidiga skeden : För säkrare kalkyler i egenregiprojekt
Syftet med detta examensarbete är att analysera nyckeltalen för produktionskostnaden som nyttjas vid investeringsbeslut i flerbostadsprojekt. För att kartlägga osäkerheterna innan investering sker tas kostnadskalkyler fram. Dessa kalkyler innehåller ofta flertalet osäkra poster då projekten är till stor del fortfarande på idéstadium och uppskattningar blir ett måste. Rapporten inleds med att riskerna, utifrån risknivå och konsekvenserna utav dem, definieras och analyseras. Följande presenteras Veidekkes önskade hantering av kostnadsriskerna och slutligen vilka möjligheter och hinder det finns inom dagens organisation för att uppnå dessa arbetsmetoder. Studien har baserats på kvalitativa intervjuer med representanter från olika yrkesroller, i olika projektskeden och från de tre olika svenska regionerna. Dessa intervjuer har visat på att de största osäkerheterna ligger i entreprenadkostnaderna, markkostnaderna och konjunkturens påverkan på bostadsmarknaden.
Externa kostnader för viltolyckor
The objective of this paper is to estimate monetary and non-monetary costs for the huntercaused by deer-vehicle collisions in Sweden. These costs include losses in hunting value as wellas time and money efforts related to the handling of wildlife casualties. The calculations arebased on available statistics from 2004 on deer-vehicle collisions involving moose, deer, roedeerand wild boar and on telephone interviews with hunters involved in the tracking of injuredanimals. Altogether, the annual loss in hunting value for moose was assessed to approximately30 million SEK based on the 2004 accident statistics. For roe-deer and fallow deer, thecorresponding figure was approximately 56 million SEK and 1.2 million SEK, while wild boaraccounted for 1.3 million SEK, respectively.
BIM Building Information Model : Hinder & Drivkraft
The construction industry is a costly business such in respect of capital for most construction defects which then require rework, tear down and rebuild again. This study is meaningful awareness of tools that can reduce this best through communication and information sharing between the parties. The construction industry is known as temporary projects organizations, where the construction project consists of several actors who have to communicate and share information between them to avoid mistakes later in the build time. These actors are bounded together thus for the duration of the project, then broken when the project has reached its end. The challenge here is for these actors to apply a tool that can help and simplify communications, information sharing, and perhaps the most important aspect is to create a routine for the association and the shattering of these actors. To implement such behavior using a tool such as BIM in the industry whose size perhaps is indescribable may be a very hard task. BIM (Building Information Model) could be seen as the solution to this problem because it acts as a portal where the actors involved must sign in and communicate, share information, and eventually create a behavior, a routine for this association and division of the actors following the end of the project. The technology could help the involved from the beginning of the project, already in the model stage, break down and prevent any construction barriers when the building has been placed in the works.
Automatisk mätning och detektering av röjande signaler
This master thesis has been performed at Sectra Communications AB in Linköping where they manufacture electronic encryption devices. In cryptology it is essential that an eavesdropper cannot find the plain text. To assure that a system is safe, all devices are thoroughly examined so that they don?t emit any secret information, so called Compromising Emanations (CE). This is done by comparing the secret signal with measured signals on the screen of an oscilloscope, a process that is very time consuming and furthermore, the risk of missing compromising emanations is high.
Utveckling och psychometrisk testning av "Pain Impact Inventory" - en jämförelse mellan två olika ansatser
The aim of this study was to develop and psychometrically evaluate an instrument for measuring the impact from chronic pain on daily life. Traditionally psychometric evaluation is done with parametric methods even if the items are ordinal data. In this study the instrument to be developed is solely based on ordinal data, and the psychometrically evaluation is done with both traditional methods (i.e. parametric statistics) as well as with non-parametric methods. These two different ways of psychometrically evaluation are then compared with each other.
Utveckling av en centrifugalkoppling tillhörande motorn HiG-145 till tävlingen Shell Eco Marathon
HiGtech är en projektgrupp på Högskolan i Gävle vilka konstruerar och bygger energisnåla tävlingsfordon. Ett av fordonen tävlar i Shell Eco Marathons prototypklass för bensindrivna förbränningsmotorer och drivs av en på högskolan konstruerad motor. Motorns effekt överförs till en kedjetransmission via en inköpt och modifierad centrifugalkoppling. Den nuvarande centrifugalkopplingen väger cirka 1,5 kg. Då en stor faktor för tävlingsresultatet är fordonets rullmotstånd, vilken beror av fordonets vikt, har målet med detta arbete varit att konstruera en specialanpassad centrifugalkoppling, vars vikt endast är hälften så stor som motorns nuvarande koppling.
Dimensionering av bärverk av stål : En jämförelse mellan Eurokod och BKR
The design regulations of Boverket (BKR) have long been the mandatory standard for construction design in Sweden. However from the end of the year 2010, the BKR will be replaced by the European standard Eurocode (EC). The transition to EC has been delayed and it is not until the second of May 2011 that the use of EC will be mandatory. Because EC and BKR differ from each other it is highly interesting to investigate and explain these differences.The purpose of the thesis is to compare the two standards and investigate how they give different results or not for the dimensioning of structures of steel with associated loads. The current project HVC (Pets Science Center) in Uppsala is used as a model for the design of the steel structure used in this study.
