The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.

The purpose of this thesis was to investigate how teenagers are attracted and motivated to maintain a relationship with companies on the Internet. Companies that have teenagers as a target market have to understand their needs and wants, in order to establish relevant relations. The study has been carried out through a review of theory within the field of study. A case study was carried out through interviews with teenagers in the ages of 15 to 19. The results from the study showed that what mainly attract teenagers to visit a website are personal recommendations, the name on the website and high rankings on the search engines.

This essay deals with the relationship between subcultures and literature. It includes an analysis of what adolescents read if they get to choose fiction by themselves. The method used in this essay is a hermeneutic method. Five novels are used in the search for subcultures and qualities and ideals within them. The essay reveals five specific subcultures, and significant features of those are presented in the analysis.

The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.

Hypercholesterolemia is one of the risk factors for cardiovascular disease. In Asia, hypercholesterolemia is less common than in the Western countries. In Asian countries, soy products are consumed in larger quantities than in the Western world, which has led to implemented research with the intention of examining soy's potential effect on cholesterol levels.Objective: To investigate whether there is scientific evidence that isoflavone supplementation from soy bean may have a lowering effect on LDL-cholesterol.Search strategy: The databases used for the systematic literature search were PubMed, Scopus and Cochrane. Keywords used were cholesterol and 9 versions of this, and isoflavones and 11 versions of that.Selection criteria: RCT articles, on humans, written in English, published from 2011 onwards, that focused on interventions with isoflavones from soybeans and its effect on blood cholesterol, the participants were over 18 years old and the study time was at least 24 weeks.

Sahlgrenska Academy at University of GothenburgDepartment of Internal Medicine and Clinical NutritionABSTRACTTitle: The connection between IBS and FODMAPsAuthor: Helena Hautamäki and Rebecka BertilssonSupervisor: Sofia KlingbergExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2013-04-10Background: IBS (Irritable Bowel Syndrome) is a functional gastrointestinal disorder, and is acommon disorder in the western population. The predominant symptoms are diarrhoea,abdominal pain, bloating, constipation, and excessive flatus. Today there are no evidence basedrecommendations concerning dietary factors for patients diagnosed with IBS, but recently certainfactors in the diet that seems to trigger the symptoms have been identified. These factors areshort-chain carbohydrates, Fermentable Oligosaccharides, Disaccharides, Monosaccharides, andPolyols (FODMAPS), which are not completely absorbed in the lumen.Objective: The purpose of this systematic review article is to examine whether there are anyevidence that a diet low in FODMAPs may induce improvement of symptoms in patientsdiagnosed with IBS.Search strategy: The literature search was performed in the databases PubMed, Scopus,Summon and Google Scholar. The keywords were ?Irritable bowel syndrome + FODMAPs?,?Irritable bowel syndrome + diet? and ?FODMAP and diet?.Selection criteria: The inclusion criteria were patients diagnosed with IBS between the ages 18and 69.

This thesis describes the redesign ofequipment designed for drying bags thatis used in Fresenius Kabis´manufacturing of their nutritionmedicine in Uppsala. The need of thistask arise during the start of thedevelopment of a new packaging line werethis equipment were meant to be used. Anevaluation of the bagdryers capacity andcapability was necessary.The work started with gathering ofinformation from suppliers of the usedcomponents and from the responsibleengineers for this equipment. Aneducation to learn how the equipmentworked and how to operate it were taken.That was followed by the creation of astudy plan were the tests were plannedto test different parameters effect onthe drying result and to see if thebagdryer managed to handle the bags ofthe correct format in the pace that theequipment should be designed for.The test results detected a need ofdesigning a unit with a function thatholds the bags in place while passingthrough the dryer in order to attainhigh quality results. The results werelater used for optimization of thedesign.

This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

The paper aims to find out how staff and users at two public libraries and one Internetcafeuse Internet. The purpose has been to find out what they find and how they use the informa­tion they retrieve. The studies are based on eight longer interviews with the staff and 33 shorter with the users, who also were observed for a week. The paper includes a background chap­ter about Internet, search tools and the studied places. The following chapters are about pre­vious research, our survey and a discussion with the results, literature and our opinion.We have found out that Internet is usually used for information retrieval.

The aim of this study is to establish whether there are any specific trends in master theses concerning knowledge organization. To identify the past and current trends a method of content analysis has been applied to 110 theses over a time period of ten years. The results of this study show that there is an increasing interest in subjects concerning for example the evaluation of retrieval effectiveness in search engines on the Internet. A subject which was popular in the late 1990:s was information technology and its different applications. This subject has since that time decreased in popularity.

The house of one of the most prominent Swedish artists of the 20th century, Bror Hjorth (1894-1968), was turned into an artists-museum and opened to the public in 1978. It has since the start held pedagogical activities and during the years developed its own pedagogical approach.I have studied the museums pedagogical work from two perspectives; visiting groups of immigrants and visiting groups of schoolchildren, in search of answers to the questions; can art be used as a way to integrate immigrants into the swedish society, and can artmuseums be a resource for schools?This essay contains my observations, conclusions and theories as well as general facts about Bror Hjorths House..

Business Process Modelling Notation (BPMN) is a way to graphically draw a diagram of a business process. A BPMN diagram consists of several so-called flow objects. These are interconnected in the graph through sequence  flows. BPMN models are merely graphical representations of business process and there is a need to simulate these diagrams for different purposes. The simulation that now is available for BPMN is that the model is evaluated by checking if it is correct.

This essay examines the olfactory reading as a possible way to make sense of a fragmented novel, in this case Sara Stridsberg?s debut Happy Sally (2004). Through close reading, the essay identifies the source of the smells, who perceives it, and how this is portrayed in the text. The smell?s position in the text is understood in relation to Maurice Merleau-Ponty?s phenomenology, where the body, as created in the literary text, is considered as a source of knowledge.
