Känslighets- och osäkerhetsanalys av parametrar och indata i dagvatten- och recipientmodellen StormTac
Three methods of sensitivity and unceartainty analysis have been applied to the operative stormwater- and recipient model StormTac. The study area is the watershed of lake Flaten in the municipality Salem. StormTac?s submodels for stormwater, pollutant transport and the recipient are cosidired. In the sensitivity assessment, the model parametres and inputs were varied one at a time by a constant percentage according to the ?one at a time? (OAAT) method and the response of the outputs were calculated.
Del projekt inom ClampCal - Utvärdering av mätmetoder för temperatur, viskositet och densitet samt röregenskaper
The dissertation were performed on SP, Technical Institute of Sweden.
The dissertation were carried out on the measurement technical department, this dissertation is a part of a bigger project, project ClampCal.
One of SP?s returning assignments are flow-measurement. When flow-measurement is performed, the flow has to be stopped so that a meter can be installed in the pipes where measurement is going to take place. At every stop there is time delay in the flow which causes the customers to loose money. This is why SP wanted to find a better solution so that measurement can be done without any stops in the flow.
Usage of a so-called Clamp-on meter was considered, but since the measurement Uncertainty is too large it takes some investigation on the parts where the largest uncertainties occur and thus find a solution that can diminish the Uncertainty as much as possible.
The parts that were considered to have an opportunity to reduce measurement uncertainties were the fluid temperature, its characteristics and the pipe geometry and its characteristics.
For the fluid temperature a Pt100-sensor with four different radii for various pipes was used.
MCNP-modell för beräkning av neutrondos och DPA på reaktortanken vid Ringhals 2
In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. The validation showed that the calculations of the model are within the requirements of a maximum of 20 percent Uncertainty for every neutron dosimeter except one, extracted after the first cycle. The Uncertainty of this cycle was mostly due to the operation data rather than to the MCNP model.The model has been used to investigate various questions concerning radiation damage. The reliability of the traditional measure of radiation damage, fast neutron flux (En > 1MeV) has been evaluated. This has been done by taking the ratio for this and another measure of radiation damage, DPA (Displacement Per Atom), for various positions and layers.
Barns upplevelse av dagkirurgi : Från ovisshet till lättnad med nyvunnen erfarenhet
Background: An increasing number of operations on children are performed as day surgery and this experience of health care may affect future hospital stays. The aim of this qualitative study was to describe children´s experiences in connection with day surgery. Method: Ten children aged six to fifteen who had gone through general anesthesia at examinations or surgery were interviewed and the content was analyzed by systematic text condensation. Result: The core category ?From Uncertainty to relief with newly acquired experience? could summarize the result of this interview study.
Förbud mot dubbelregistrering av fartyg
In a recently published official Report from the Swedish Government (SOU 2010:73) a leg- islative proposal has been introduced. Its main purpose is to prevent parallel registrations of ships that are bareboat chartered to other countries. The legislative proposal claims that by preventing parallel registration of ships the Swedish Maritime Code will better corre- spond with the UN convention on the law of the sea.The UN convention on the law of the sea clearly states that ships are forbidden to fly two flags. There is however no restriction concerning parallel registration, simultaneously, in two registers. A ship that is bareboat chartered out from Sweden does not fulfil criteria re- quired in order to be deregistered, according to the Swedish maritime code.
Infoteket om funktionshinder : Information om funktionshinder som vägen till empowerment
The aim of this master?s thesis is to investigate a information center called ?Infoteket om funktionshinder?. The purpose of Infoteket is to collect information about disabilities and make it accessible to people with disabilities, their relatives and public. In this survey I will analyze how Infoteket can help people with disabilities to achieve empowerment. I use empowerment as a theoretical framework as Jay A.
Inramning av klimatförändringar : I svensk dagspress 2012 och bland unga vuxna
Something that all people have come across and more or less experienced is climate change. Climate change in itself is a very complex problem since there are no borders between countries that can stop the problem. The link between science and the public is largely in the hands of the media, since the media play an important role in defining environmental issues and to inform the public about research findings. In recent years, reports from the media showed a slightly skeptical and uncertain picture of this problem. This is despite the largely prevailing consensus among climate scientists that there is an anthropogenic climate change.
Val och byte av företagsform : En studie gällande skatternas roll vid val av företagsform samt de skattemässiga konsekvenserna vid ombildning av företag
In today?s society it is not uncommon for people to move across borders. We are more likely to work and study in other countries, initiate cross-border relationships, acquire property in other states and change our residence. Therefore it is not uncommon for a per-son to leave inheritance in several states. The laws of succession differ between countries which creates an Uncertainty among the devisors when planning their successions.
Ethanol for Scania's Future - A Scenario Based Analysis
Abstract Title: Ethanol for Scania?s future ? A scenario based analysis Authors: Anna Hansson and Julia Persson Tutors: Annette Cerne ? Department of Business Administration, Lund University Jonas Holmborn ? Head of Advanced Combustion, Engine Development, Scania Lennart Thörnqvist ? Department of Energy Sciences, Faculty of Engineering, Lund University Problem: Oil-based products are the dominating fuels in the transport sector but alternative fuels are currently challenging the world-wide dominance. The large number of alternative fuels that are under development at present makes the future fuel-market impossible to predict. Scania?s ethanol project is associated with a number of Uncertainty factors that are beyond the company?s control.
Kommunal redovisning : Ett verktyg för kommunikation och ansvarsutkrävande
Background: Previous studies have shown that intuition occurs in decision making in small enterprises. However, these studies have not illuminated which decision attributes leads to intuitive decision making.Purpose:The purpose with this study is to contribute with an increased understanding of which decision attributes leads managers in small enterprises to use intuition in decision making and why these decisions attributes have an impact on the role of intuition. The follow-ing research question will be answered in our study: Which decision attributes leads to intui-tive decision making in small enterprises, and why?Method: To answer the research question we have conducted semi structural interviews with managers in small enterprises to achieve a deeper understanding of the role of intuition. We have also used a method called Visual Card Sorting as a complement to the semi structural interviews.Result/conclusion: The result of our study indicates that the relevance and the Uncertainty of a decision have the greatest significance in the use of intuition in decision making in small enterprises.
Att vara partner till en patient med akut hjärtinfarkt
Acute myocardial infarction is a serious diagnosis. Both the patient and the loved ones experience an immediate Uncertainty. To be able to emotionally support the patient´s spouse, the nurse in the coronary care unit must be prepared to also encounter the world of the spouse. The aim of this study was from a nursing perspective to illuminate how life was experienced during the first two months by the spouse of someone, who was stricken by a first time acute myocardial infarction. Interviews with six spouses were conducted.
Man promenerar i dimma - En studie av flyktingars berättelser om asylprocessen
This essay is based on seven lifestoryinterviews with people who are undergoing orhave undergone a long asylum process. Four women and three men have contributedwith their stories about their experiences of waiting for a determination of theirapplication for residence permit. The main aim of the essay is to give betterunderstanding of how to be a refugee and a long asylum process affects people's abilityto narrate and thus examine their opportunities to be active in the construction of theirown identity.The questions that are debated and discussed are:? What can it mean for an individual's identity to escape her country and for a longtime wait for decision of asylum?? What stories can be told?? What reality are highlighted as central in the stories?? How do they handle their situation and give meaning to their lives?The analysis is based on two main theoretical perspectives: narrative theory and identitytheory. The approach is that people create meaning of events through storytelling andthat they through this process of narrating construct (and reconstruct) their identities -the self image as one have and wants to present to others.In the analysis three different types of stories are distinguished, stories that arerepresented in the empirical material: the story that can not be told, the story that mustbe told and the story that are gladly told.

Det är osäkert vad det beror på : Multiprojektstyrning i forsknings- och utvecklingsenheter
BACKGROUND: Project based structures has become more and more common in the organizations of today. As the project based structures are given a more central role in the organizations the interdependencies between the projects are getting more attention. These structures need a new type of control to meet the unique challenges that arise. The researchthat has been done has been concentrated around the project form and the projects internal control, the area of multi-project management is therefore relatively unexplored. The few existing studies on the subject focus on projects in the construction industry why research inmore complex fields of business have been requested.PURPOSE: The purpose of this thesis is to explore and analyze how knowledge intense multi-project organizations manage their project activities, and to determine how different organizational characteristics affect the need for management control systems.METHODOLOGY: The empirical data has been collected through interviews with personnel in BT Products R&D, Gambro R&D and AstraZeneca Development.
