Mälarens vattennivå i ett framtida klimat

The discharge from Lake Mälaren is regulated to keep the lake water level within limits set by a water decree. Despite this, in the year 2000 the lake water level rose above the upper limit. Studies conducted at the climate modeling unit Rossby Centre at the Swedish Meteorological and Hydrological Institute (SMHI) indicate that the inflow to the lake may increase in the future. A flood in the area will, among other things, strike infrastructure and residential districts.The aim of this study was to investigate the water levels of Lake Mälaren in future climates. In addition to this possible future expansion of the lake discharge though the sluice gates in order to keep water levels below limits set by the water decree and to prevent flooding of the shoreline were discussed.

Svensk vindkraft

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

A risk analysis of moose close to roads

For many decades the increase in traffic volume, expansion of highways and infrastructure has lead to an increase of wildlife vehicle collisions which are unfortunately very common in many countries today. They cause great deal of material damage and even kill humans or wildlife. Measures in the form of warning signs, under- and overpasses and fencing have been implemented for a long time with the help of observation by hunters and collisions sites. However this study focuses on the moose?s perspective and the variables that, both spatially and temporally, could have an effect on why and when moose are close to certain types of roads.

Samtiden och framtiden: En studie av mottagandet av två svenska dystopier och deras samtidsförankring

The aim of this Masters thesis is to deepen the understanding of how society affects literary criticism by studying the reception of two Swedish dystopian novels and their contemporary anchorage. The questions that we answer here are concerned with how critics have drawn parallels between the novels and events occurring in the contemporary society, and how the critics outlook on the future are connected to ideas about the future in the novels. The first novel, Kallocain 1940 by Karin Boye has been interpreted as a critical statement directed towards totalitarian ideologies. The second novel, After the Flood 1982 by P C Jersild, has been seen as a warning against nuclear warfare. This qualitative study is based on 41 reviews from Swedish daily press.

Samhällets Sårbarhet för Klimatförändringarna

The effects of the climate changes are expected to generate several substantial direct and indirect consequences on both ecosystems and societies. It is the extent of the negative consequences that determents the vulnerability of the things or the ones exposed. The knowledge of the effects and consequences by a changing climate provides an opportunity to take measures to reduce the vulnerability.Our society?s vulnerability depends on how we choose to act out of the existing knowledge and what measures we choose to take. Karlstad municipality has good knowledge and perception of the increased flood risks the climate changes will generate and the probable consequences that most likely will follow. How the municipality decides to manage the flooding issue is not just affected by the will to mitigate the vulnerability but also by the vision to increase the number of citizens.

Översvämningsrisker längs Funboån

Flooding events are no longer rare, floods occur all over the world. Accordingly, it is vital for the society and different authorities to work with flood mapping. To meet the goal of Uppsala kommun to map the risks of floods in Uppsala län, a map of the different areas around Funboån which are inside the area of risk for flooding have been developed.In the work, cross sections and the water flow have been measured. Moreover, an echo-sounding have been carried out in Funboån to map the bottom topography. From the bottom map and laser scanned data covering the study area, a terrain model was created.

Bakomliggande faktorer till revisorers utfärdande av going-concern varningar : En studie om vad som orsakar going-concern varningar för finansiellt belastade företag

Introduction: The auditor's going-concern warnings express the quality assurance of information and if these are wrongly based, the stakeholders become deluded. Previous research has shown that auditors do not have any major difficulties in identifying companies that are financially distressed to the extent that they risk receiving a going-concern warning. International studies on the determinants of going-concern warnings have instead focused primarily on the auditor's decision regarding companies that are already in bad shape financially. Auditor grounds for issuing a going concern warning may be linked to factors related to the client, the auditor, the audit firm, the relationship between the client and the auditor and the environment. Purpose: The purpose of this study is to find out what specific factors that affect the auditor issuing going concern warnings for financially distressed companies.

Simulering av översvämningar i Byälven

Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.

Sambandet mellan revisionskvalitet och längden på revisionsuppdraget : empirisk undersökning av Going Concern varning

That an auditor brings good quality to the work he is performing is of great importance, not only for the company in question but also for its stakeholders. The information that the company disclose gets more credibility because of the auditor quality assurance. That the auditor tenure would affect the quality has been researched with different results, dependent on the legislation in the current country or region. In this paper we study how audit quality is affected of the audit tenure in Sweden. Based on research made in Belgium we have formulated hypothesis with factors that can affect the audit quality.

Simulering av översvämningar i Nedre Dalälven

Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.

Ledningsarbetet hos ett krisföretag : en analys av ledningens hantering av en ekonomisk kris

Almost every company sooner or later ends up in a more or less difficult economical situation. The reason for the economical crisis varies for each individual case but common for them all is that it is the management group that has failed in their work to guide the organisation to avoid a negative result. The next common denominator is that it is the management group that has to handle the changes in the company's environment and lead the company out of the crisis. But how can they do this and take decisions in a rational and effective way and is there warnings signals that the management group missed before the crisis was a fact? This is some of the questions that this study is going to discuss and analyze. The aim of the study is from a management perspective chart the strategic work of the company's management work when handling an economical crisis.

Evaluation of Xilinx System Generator

This Master?s Thesis is an evaluation of the software Xilinx System Generator (XSG) and blockset for Matlab. XSG is a module to simulink developed by Xilinx in order to generate VHDL code directly from functions implemented in Matlab. The evaluation was made at Saab Avionics AB in Järfälla, north of Stockholm. In order to investigate the performance of this new module XSG to simulink, a model of a frequency estimator often used in digital radar receivers were implemented in Matlab using XSG.

Höjning av vattennivån i Mälaren : Ett hot mot Stockholms centrala delar vid en framtida klimatförändring?

In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.

Demokratiutredningens arv : En idealtypsanalys av riksdagsmotioner gällande lobbyism

For the last decades, Sweden has transformed from a state with strong elements of corporatism, to a governance of pluralistic character. This development has opened up to a new form of participation ? lobbyism ? which since has spread and commercialized. Because of this, a report on the state of Swedish democracy ? Demokratiutredningen ? was issued to examine the phenomenon of lobbyism as it was feared to challenge the functioning of a representative democracy.
