The risk analysis was conducted with a preliminary hazard analysis, PHA and event trees. The analysis focuses only on the risk posed to employees and material damages at the plant. No third person injuries have been considered. Another purpose of this report is to study risk awareness and risk communication concerning dust explosions.

Självkompakterande betong vid platsgjutning av anläggningskonstruktioner

By using modern methods of casting concrete, cast in place can get more effective and industrialized. A modern method is self compacting concrete. By using this type of concrete, advantages like improved working environment and rationalized construction can be reached. Because the concrete doesn?t need to be vibrated, the amount of staff on site and the noise can be reduced.

RO hantering på ABB, TPE

Arbetet har utförts på ABB i Ludvika med avsikt att förbättra revisionsprocessenför kontroll och skydd. En revision är en ändring på ett godkänt och klarmarkeratobjekt. Då objektet i fråga redan kan vara levererat till kund och man behöver göraen ändring krävs en strukturerad process för att utföra denna ändring. Processen föratt göra detta är i dagsläget komplicerad och kräver en hel del administrativt arbete.Processen använder sig utav ett antal program för lagring och databaser så som,Lotus Notes, HiDraw Studio, och HiDra32.Avdelningen för kontroll och skydd är i fasen att övergå till ett annat elCADsystem, Engineering Base. Detta är också en av anledningarna att man önskar en nyprocess för revisionshantering.Arbetet bestod till en början av inlärning av den dåvarande processen.

Patientjournalen på fickan - en studie som visar att handdatorn kan stödja distriktssköterskans yrkespraktik och hur det grafiska gränssnittet utvecklats när distrikttsköterskor deltagit i designprocessen.

Projektets syfte var att undersöka om en handdator kan stödja distriktssköterskans arbete. I rapporten beskrivs hur vi tillsammans med distriktssköterskor har iakttagit i vilka situationer handdatorn kan vara ett hjälpmedel. Om patientjournalen är tillgänglig via handdatorn vid hembesök skulle det styrka de av oss utvalda nyckelorden som representerar distriktssköterskans yrkeskunnande; "seende", lyhördhet, kommunikation, flexibilitet, prioritering, beslutsfattande, dokumentation, framförhållning samt utveckla ett minne och självständighet. I rapporten skriver vi också om hur distriktssköterskorna tillsammans med oss har påverkat utvecklingen av det grafiska gränssnittet i designprocessen. Vi visar med mock-upbilder hur denna process har framskridit och vi pekar på hur viktig användarmedverkan är.

Den arbetssökandes upplysningsplikt : En allmän avtalsrättslig princip påverkad av arbetsrättsligt skyddstänkande

The general contract law principle of loyalty between negotiators, in deliberation, leads to a duty of disclosure for negotiators. The extent of this duty of disclosure is influenced by many different factors; amongst others the type of agreement, the negotiators knowledge and opportunity of procuring knowledge. The general duty of disclosure is both a part of the contract law principle of loyalty between negotiators in negotiating a contract, and an indirectly statutory obligation, that, if neglected will lead to nullification of the agreement. The legislator has stated that the general contract law, Lag (1915:218) om avtal och andra rättshandlingar på förmögenhetsrättens område (avtalslagen), should be used to regulate negotiating of contracts, including the negotiation of contracts of employment. In arbetsdomstolens judging, additional factors have been weighed in, and the judgement is done also through the use of a concept taken from employment law, the concept of ?saklig grund för uppsägning?.

Möjligheter och problem med integration av hanteringen av antagonistiska och olycksrelaterade risker - En jämförelse med utgångspunkt från två konsultföretags arbetssätt

The aim of this report is to investigate, on the basis of two consult agencies perspectives, what the possibilities and obstacles are to integrate the work with antagonistic and accident related risks. The report is based on two consult agencies where each agency´s work procedure is represented by a risk management method. The work with accident related and antagonistic risks is analysed and evaluated compared to four different components. The components are risk management process (IEC´s and FEMA´s model), driving forces, education and competence, and resources to control risk management with COSO?´s ERM framework.

Digitalisera loggboken : En analys av utmaningarna med att utveckla IT-stöd för kunskapsintensiva verksamheter

Failed system development projects are a common sight within the IT-industry. During the last ten years we have seen several more or less disastrous high profile projects being reported in the news. One aspect that might hold some of the responsibility for these failures is the fact that more organisations are knowledge intensive which makes their work processes difficult to capture in computer systems. How requirements engineering is handled becomes even more important in these cases, where processes are unpredictable and rely on individual judgement and knowledge. In this study we have examined the challenges of developing systems for knowledge intensive businesses through a method of qualitative case study of a university laboratory.

Konstruktion av säkerhetslagerför svänghjul

This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.

1-D Modellering av Piezoelektrisk Injektor

A piezoelectric injector was modeled, in this Master Thesis Project which was carried out at Scania CV AB in Södertälje, in GT-Fuel. GT-Fuel is simulation program from Gamma Technology.The simulation model for the piezo injector was divided into a hydro-mechanical system and an electrical system (Piezoelectric element). First the hydro-mechanic model was duplicated from Advance Continuous Simulation Language model (ACSL). The simulation results were then compared to the ACSL, to verify that the hydro-mechanical system was modeled correctly. The simulation results for the electrical model were also compared with a Simulink model.

Tillämpning av Unified Process och Design Patterns vid integrering av system

The computer consultant company Create in Lund AB wishes to facilitate their invoice routines, as it at present is required that the administration finds and compares information from two different systems.The purpose of this thesis is to develop an invoice management system that simplifies the invoice management process for the administration at Create. During the development of the system, I have chosen to follow the software development process Unified Process and also tried to find design patterns that can be applied to the integration.The result of my project is a self-contained application developed using the Java programming language that communicates with the databases of the other two systems and presents relevant information to the user as a set of invoices. Of the 23 design patterns I studied, I used four of them in the invoice management system. However I couldn?t find any connection between any design pattern and the integration of systems.
