Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

This thesis seeks to investigate the relationship between municipal policy for housing supply and the planning of new housing in Sweden. Through a case study of Göteborg municipality and a comparative content analysis of Göteborgs policy for housing supply and a number of plans featuring housing the analysis seeks to investigate the effect of policy for housing supply as a tool for securing the demand for housing in the Swedish municipalities. The thesis also seeks to discuss its findings using theory concerning the implementation of policy and the general planning situation for Swedish municipalities today. The result of the analysis shows that most plans fail to regulate most of the content suggested in the policy for housing supply, particularly regarding aspects such as pricing, type of housing and type of ownership. The result also points towards a relationship regarding the prevalence of municipal land contracts and compatibility to policy for housing supply as well as a connection between how extensive the plans are in their proposed land use and their compatibility with policy for housing supply.

Introduction/Background: Economic evaluations help decision-makers to make informed decisions regarding resource allocation. Information generated from CEA can support evaluations of a new intervention with current praxis. The evaluations also provide information as to whether an intervention is cost-effective, both in economic terms and in health gains. Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.

The purpose of this work was to see if it was possible to rebuild an old dairy house into a house fore sheep production. The goals fore the work was to see witch kind of production model was suitable, how the actual drawing would look like and witch kind of interior was needed. The building was built in the beginning of 1900. It is located on the mountain Kinnekulle in Sweden. It was a big production fore its time and hade about 60 dairy cows. It was a lot of hard work because the floor was built by big stone blocks and it was very hard to rebuild when some more automatic solutions came fore handling all the manure. The idea of remaking the building came when we rebuilt the roof fore 5 years ago.

Purpose: The main purpose of the thesis is to examine the profitability of Momentum Strategies on the Nordic stock markets. This will provide insight and contribute to the debate on efficient markets. Finding profitable Momentum Strategies will provide strong evidence of inefficiency in the market. A secondary purpose is to examine factors which might cause or impact the profitability of the Momentum Strategy. We will look closely at the relationship between the profitability and factors such as risk (CAPM-beta), market capitalization, trading volume and seasonality.

The union organization rate has continuously diminished since the mid 90's. The aim of this essay is to investigate non-members approach to the union. Central questions are what personal experiences the respondents have of the union and how they view the union as a phenomenon. According to previous research the main cause of the great decline in membership to LO are the increased membership fees to the union and the unemployment insurance funds (UIF) in 2007. The increased fee led to a greater accumulated cost for those who were both union- and UIF -members, which had a negative effect on the membership numbers for the union.

Title:Change strategies in the transition towards a cashless banking systemLevel:Final assignment for Bachelor Degree in Business AdministrationAuthor:Elin Lånström och Vildana SmailagicSupervisor:Stig SörlingDate:August 2013Aim:In our study, we compare what it is that drives a bank to implement changes in their business, what problems these changes may bring, and how organizations deal with these. We do this by studying how different banks choose to relate to the handling of cash.The questions we ask ourselves are:? What lies behind the decision to make changes in cash management?? How is the change implemented in practice?? What do banks think this change will mean for the future?Method:The study was conducted with the help of a qualitative scientific method. We conducted interviews with representatives of four banks, and made use of secondary data in the form of scientific literature and scientific articles.Result & Conclusions:Organizations implement changes in order to adapt and achieve balance with their environment but also within the organization itself. Our study shows that the decision to introduce cashless branches is mainly a result of banks' efforts to become more cost efficient.

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.

Syfte: Syftet med den här uppsatsen är att undersöka läkemedelsföretag för att sedan jämföra läkemedelsbranschen med stockholmsbörsen för att se hur läkemedelsbranschen påverkats av finanskrisen på slutet av 2000-talet.Metod: Studien bygger på en hypotesprövning och författarna har valt att använda en deduktiv ansats och en kvantitativ datainsamlingsmetod för att samla in data kring läkemedelsaktier.Teori: Studiens analyser bygger på två teoretiska modeller. Den ena är CAPM (Capital Asset Pricing Model) som är en modell som används för att räkna fram avkastningskravet för aktieägarna. Det andra är ett teorem (Modigliani-Millers) avseende kapitalstruktur och som behandlar marknadsvärdet på ettbolag oberoende av finansieringsform eller distribution av utdelningar.Empiri: Jämförelser mellan Stockholmsbörsens generalindex och de fem största läkemedelsbolagen visar på att läkemedelsbolagen delvis följer börsens utveckling. Men över tid så visar sig läkemedelsaktierna vara stabilare och återhämtar sig snabbare än börsen som helhet.Slutsats: Till en början kan man se att finanskrisen har påverkat hela börsen inklusive läkemedelsbranschen. Dock visar en närmare observation av händelsen att läkemedelsaktierna återhämtar sig betydligt fortare och att de totalt sett inte svänger lika mycket..

This survey was made to investigate the possibility of using an alternative method of fencing inSwedish forestry. The most common way of fencing in Sweden today is made by a two meter highmetal net that is attached to turned impregnated poles. The fencing methods that have beeninvestigated is a fencing system made completely out of wood so called ?German wood fence?.Browsing of game in forest regeneration areas is often a big problem and some kind of protection ofthe plants is often necessary. There is several ways of building fences and the most common way isto use metal nets and impregnated poles, this leads to a problem when the fence has profiled itspurpose.

This project is a study in how to represent the Swedish magician and variety artist Carl-Einar Häckner in a web-based environment. With a starting point focusing on illustration I wanted to produce a web environment that would function as a prototype for a webpage. My personal aim was to explore and gain new experiences from working in a digital interactive environment. I wanted to use animation and illustration to create an atmosphere and communicate emotions, and in the end find out a way of how to integrate that with a more text based content. The project is a personal project based on my interpretation of the work of Carl-Einar Häckner and an effort to translate Häckners expression and the emotions he evokes in his variety shows into image..

The white-backed woodpecker is a forest bird being critically endangered in Sweden. The species is dependent on older forests rich in deciduous trees and dead wood. The main problem for the survival of this species is present shortage of habitat. Conservation work on this umbrella species is at present focused on finding remaining or emerging habitat networks. Large areas are scrutinized in search for suitable habitats to be protected or managed for the species sake.

In 2007 Swedish Meats, the dominant Swedish meat-producers cooperative sold its slaughtering and processing industry. The goal of a producer cooperative structure is to create value for members through vertical integration, and to strengthen members? market position. When Swedish Meats sold the slaughtering and processing components, it ceased in some respects to serve the function of a cooperative. This is a lost opportunity for both members and non-members, because Swedish Meats as a functioning cooperative could have exploited its dominant market position to positively effect producer?s prices.

The purpose of this project has been to cut production costs for the fascia panels ofGetinge?s largest autoclaves. The cost for the stainless steel plates currently used is veryhigh. An alternative material solution could cut costs significantly.In addition, improvements have been made to the instrument tower which is a central partof the fascia panel. As a result of the new modular design in a new material theinstrument tower has been improved in several aspects..
