Mätning av partikelmassa i avgaser från en dieselmotor

This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can Handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.

Prefabricerade Passivhus

European Union has made a new decision that all new built houses by 2020 shallbe near-zero energy houses. Boverket?s definition of near-zero energy housesintends buildings with good energy performance in which a proportion of theamount of energy that must be added to the building is made of renewable energy.Passive House is a set of requirements from FEBY designed to build energyefficient buildings. This is achieved by reducing loss of heat through the buildingenvelope and to take advantage of the passive heat from solar radiation,installation and heat sources like people living in the house.This project has been made with help of Anebyhus and one of their model houseshave been examined from the report?s issues, including Anebyhus?s energyperformance, requirements for the manufacturing and assembly, how theenvelope must be improved to fulfill the requirements for the Passive House andwhat energy calculation programs are available on the market.The report aims to provide solutions for energy efficient houses that are adaptedfor production of house building.Two visits to Anebyhus has been done to study their manufacture and assemblyof building elements.

Han och hon möter vi och dom ? den universella välfärdspolitikens akilleshäl : En studie av kön och ras i svensk förvaltning

Gender politics in Sweden is considered unique because gender policies (jämställdhet) are integrated into national politics and politicised both in the public and the private sphere. The Swedish case is therefore considered a role model by many feminist scholars.This view has been criticised by both post modern feminists and public administration scholars. Critics imply that the increased immigration and more heterogeneous population have led to a new challenge for state institutions. The Swedish model, with its universal welfare solutions, lacks the ability to recognise differences within groups. Universal solutions that treat everyone the same is no longer the most just way to treat people.The growing use of goal orientation in Swedish public administration has increased the civil servants discretion in the implementation process, and thereby the space for differentiated treatment.

Kort speltid ? djupt intryck: spel som hyrfilm

SVENSKA: Vårt kandidatarbete gick ut på att ta reda på om det var möjligt att utveckla ett kort spel i hög teknisk kvalitet och ändå skapa ett djupt intryck på spelaren. Under projektets gång utvecklade vi, med hjälp av UDK (Unreal Development Kit), ett skräckspel i 3D till PC vid namn The Horror at MS Aurora. För att erhålla den höga tekniska kvaliteten som vi var ute efter användes metoder som räknas som standard för stora speltitlar på marknaden: Animationer spelades in med Motion Capture och musiken skrevs med en full symfoniorkester i åtanke. Innan produktionsfasen tog vid gick alla gruppmedlemmarna igenom en research-fas, där var och en satte sig in i de områden som skulle komma att vara aktuella under produktionen (d.v.s. hur UDK fungerar, musikteori och orkestrationsteknik, hur man arbetar med Motion Capture-data o.s.v.).

A vulnerable group in society is people with ASD (autism spectrum disorders) or autism. This group seems to increase, mainly due to genetic factors but also environmental problems. Medical research has accelerated in the U.S. and Europe. The biggest problem for people with disabilities is the inability to communicate, both verbally and socially.

Bolagsstyrning : En kartläggning av styrelsers arbete med strategifrågori svenska börsnoterade bolag

Corporate governance intensified due to the corporate scandals in the USA which led to a new law the so called Sarbanes-Oxley Act (SOX).In 2005 the "Svensk kod för bolagsstyrning" (The Code) was introduced. The main purpose of The Code is to strengthen the confidence in Swedish companies quoted on the Stockholm Stock Exchange. The Code focuses on the working process of boards. The rules set by The Code places higher demands on the board.  Among many other duties the board has to establish long term operational goals and strategy.

Beräkningsmodul för ett förbättrat offertförfarande och minskad icke-värdeskapande tid

In early January 2010 the authors participated in a meeting with the chief engineer for a company in which a central part is manufacturing of printed circuit boards (PCB). At this meeting it emerged that the machinery and production methods have changed substantially since the early 1990's. The spreadsheet for preliminary production time calculations by the company is today based on conditions from almost 20 years ago. The company has over the years been trying to adjust the spreadsheet template. The result of these adjustments has filled it with historical residue, something which makes the template difficult and time consuming when the primary user tries to Handle it.The purpose of this study was to help the company increase its accuracy in the representation of the production times for the different PCB-based products by developing a new costing model based on an already existing but inadequate spreadsheet template. The company also expressed the wish that the new costing model would be less time consuming to work with.The methods used to achieve the goal are interviewing, participatory observations and meetings with relevant persons. The data obtained were analyzed using the theory on PCB production and visualization of data.

Inte bara en kommentar : En studie om krishantering på sociala medier

AbstractTitle: It?s not just a comment ? a study about Crisis Management on Social MediaAuthor: Malin Pettersson 910624 and Amanda White 920310Year: Spring 2014Level: Bachelor degreeDepartment: School of Business and EconomicsSupervisor: Carina HolmgrenExaminer: Frederic Bill Purpose: The purpose of this paper is to develop and test a theoretical model for Crisis Management on social media. Method: The overall literature that was found consisted of traditional Crisis Management and the communication that goes with it, and it was mainly written for traditional channels such as newspapers. The theories could not concretely describe how organizations should Handle crisis in Social Media. Therefore, this study focuses on if and how organizations can use the traditional theories when working with crisis management in social media. Through a qualitative method the study has examined and tested the model on three crises, and subsequently improved the model based on the empirical material and  the analysis that was made. Conclusion: The conclusion found that organizations need to adjust their crisis management after following guidelines for it to work on social media:-    Strategies should be limited to only one, and be either a rebuilding strategy or a bolstering strategy.-    The focus should be on emotional communication, and regarding the rational aspects the focus should be on actual actions and plans for the future.-    Clear guidelines for what type of questions and critics that should be answered should be set.

Ovisshet, ett begrepp att räkna med. En begreppsanlys

Abstract This Concept Analysis according to Walker & Avant (1995) studies the concept of uncertainty in the nursing context. It consists of four parts where uncertainty in general have been encircled in a semantic analysis (part one) and a qualitative content analysis consisting of an questionnaire, distributed to the staff members at one nursing and medicine institution, with an open question about the meaning of uncertainty (part two). The third part is a literature study of the nursing context to find out how uncertainty is described (part three). Part four is the actual concept analysis based on the three first parts. Uncertainty in the nursing context is an individual conscious experience witch is changeable and impressionable. It is chained together with its antecendents and consequences.

Revisorernas oberoende ifrågasätts : går det att sitta på dubbla stolar, få dubbla inkomster och ändå bevara oberoendet?

The recent accounting scandals in large companies in both USA and Europe, such as Enron and Scandia, have led to a huge debate about the quality of financial reports approved by auditors who, at the same time, offer consultancy service to their audit clients. Many researchers and experts argued that there is a role conflict when an auditor offers consultancy service to audit clients. They argue that the main duty of an auditor is to verify the truthfulness of the company's financial statements. Giving consultancy service to the audit clients will impair the auditor's role to examine the company's books independently because of the economic bond between auditors and audit clients.As a result of the Enron scandal, the legislators in the USA have made restrictions to how auditors provide non-audit service to audit clients. However, the legislators in Sweden, unlike the US, did not choose to introduce such restrictions.

Jämförelse mellan BKR/BSK och Eurokoders behandling av utmattning i traversbalkar med tillhörande svetsfogar

This report has been performed for WSP Construction Design located at Arenavägen 7 in Stockholm. WSP Construction Design is one of the leading departments in Sweden in construction solutions regarding everything from building construction to industrial building. Great competencies regarding steel, wood and concrete constructions are available within the department which is well sought.Crane girders used in the industry are exposed to large loads that vary over time that includes instantaneous lifts and the crane girders movement which lead to the phenomenon fatigue in the crane girder and its ingoing welds. A control of fatigue needs to be performed after a certain lifespan measured in time which in turn is converted to a number of loadcycles. When the number of loadcycles amounts to a greater number the input welds resistance will have been reduced and the rate of utilization thereby increased.
