Effektivisering av medicinska laboratorier
Background ? The last 20 years healthcare has been facing increased demands on efficiency and increased customer satisfaction. This despite reduced resources and increasing demand. These demands are presents in all departments within healthcare organisations, including medical laboratories that currently receive an ever-increasing number of remittances. Laboratory flows are quickly becoming overloaded with samples and related materials.
Utvärdering av ett Bränslecellsdrivet Flygplan.
With the increases in fuel costs due to the depletion of the world oil reserves and the increase of greenhouse gasses as a consequence to using oil as a fuel many companies are looking to new and innovative ways to power their aircraft. One of these new ways to power an aircraft is using fuel cells powered using hydrogen and oxygen, thus producing nothing but water vapour and small amounts of nitrogen dioxide as well as trace amounts of other emissions. Both Boeing (1) and Politecnico di Torino (2) have shown that it is possible to build an all-electric aircraft powered by fuel cells. Both flights used small, two-seater aircraft and a constant between them was the loss of the co-pilot seat due to weight and lack of space. As this paper will deal with a commercial aircraft a primary concern is the cargo and passenger capacity and whatever impact switching propulsion system has on these.
Ett steg framåt, två steg bakåt? Direktiv 2005/29/EG:s effekt på det svenska konsumentskyddet inom marknadsrätten
På EU:s inre marknad ska fri rörlighet råda. Trots det tvekar konsumenter inför att handla över gränserna. Många konsumenter känner en osäkerhet inför andra länders lagar och oroas över att skyddet mot ohederliga näringsidkare inte är det samma som i deras eget land. Denna osäkerhet undergräver den inre marknaden. För att motverka denna osäkerhet har EU antagit direktiv 2005/29/EG om otillbörliga affärsmetoder.
Helikopterrånet : En fallstudie om interkommunikationen mellan gärningsmännen
The aim of this study is to analyze how intercommunication between offenders are presented with artefacts during the planning and implementation of a robbery in a cash depot in Stockholm. The methodological approach is based on empiricism from police investigation protocols, which leads this study to a case study. The ambition is to analyze the empirical material from a sociocultural perspective. The results shows that the offenders use artefacts to plan the crime with artefacts within an internal intercommunication between the offenders. After the planning artefacts such as a helicopter, explosive material, telephones, saws and ladders have been used in an intercommunication to implement the robbery which leads to an analysis that hierarchy depends on the role of the artefacts, only when technical artefacts are included in the term of hierarchy..
Genom statistisk analys utvärdera geometriska parametrars påverkan på ett XPI- cylinderhuvuds snurrtal
This Master Thesis is a product development project that has been carried out in cooperation with Scania CV AB. The purpose has been to find the relationship between geometric parameters and the swirl number for an XPI- cylinder head in order to improve the design specification.The increased focus on environmental issues from society leads to tighter emission legislations for the truck manufactures. In order to drive the development forward considerable resources are spent on research and development on diesel engines and its combustion process. The inlet air has a significant impact on the formation of emissions and the flow that is desired is called swirl. Swirl is achieved by making the air rotate around the vertical axis of the cylinder.Earlier cylinder heads that has been developed at Scania CV AB have shown clear relationships between geometric parameters of the cylinder head and the swirl number.
Flygplanstillverkning : Fixturkoncept till robotgradning
Volvo Aeros flygmotortillverkning i Trollhättan har infört ett antal nya detaljvarianter i produktionen. Detta har medfört att den robotcell som är avsedd att utföra en avgradningsoperation är i behov av uppdatering av både hårdvara och mjukvara. Denna rapport följer framtagningen av fixturkoncept som möjliggör att robotcellen kan användas även till de nya detaljerna. De förslag som arbetats fram sträcker sig från enklast möjliga till mer avancerade och nytänkande funktioner. Samtliga funktioner och koncept har genomgått gallringar i ett flertal steg.
Ord och ingen handling?
Is Försäkringskassan, one of Sweden?s largest organizations, an equal place to work in? Dosex, ethnical background or age matter when being treated by colleagues and managers?In this thesis I try to, through interviews with both the Human Resources-departement andsome administrators at Försäkringskassan, find the answers to how the organization?s internalwork regarding equality functions. To help me with the analysis I use both discourse theoryand gender theory. I find a discrepancy between the Human Resources-department?s and theadministrators? view of how the internal equality work is run.
Datasäkerhet : Hur man skyddar sig mot interna hot
As the companies of today are good at protecting themselves against external threats, but are having problems with internal threats, we focused on how information can be protected from ending up in the wrong hands. First and foremost to protect information from employees who might steal it and sell it to another company. Since the security investments needed are connected to the financial costs of implementing them we have tried to create a balance between the investments needed and the cost of implementing them. The different kinds of protection needed are first and foremost protection to make data less accessable, passwords and traceability. While it is hard for us to estimate the amount of money a company lose by the hour when the production stands still, we have not been able to use any of the excising models to calculate the profit of installing countermeasures.
En optimierande kompilator för SMV till CLP(B)
This thesis describes an optimising compiler for translating from SMV to CLP(B). The optimisation is aimed at reducing the number of required variables in order to decrease the size of the resulting BDDs. Also a partitioning of the transition relation is performed. The compiler uses an internal representation of a FSM that is built up from the SMV description. A number of rewrite steps are performed on the problem description such as encoding to a Boolean domain and performing the optimisations.
En studie om vad som motiverar expats att stanna i företag
A flat organisation makes a horizontal career development possible, which means that it is more important to develop an individual?s knowledge base than to gain a higher title. This leads to a personal development, which motivates expats to stay. Since the responsibility of the career development mostly lies on expats themselves, companies should create conditions that make individual, internal job search possible. Like in IKEA:s case, it can be done through a strong and prestige less company culture, that penetrates the whole company.
Kvinnliga ledare kommunicerar : Motiv och former inom den svenska mediebranschen
From an early age kids learn that their good performance and efforts will be rewarded. Unfortunately, not all leaders in the media industry are rewarded or given the same opportunities to exercise their communicative leadership, according to studies in media research. The aim of our study is to highlight female managers' experiences of their communicative leadership in the Swe-dish media industry. This study was based on qualitative interviews with four female respondents in management positions. The core of the study concerns female communicative leadership and interpersonal communication.
Modellering och simulering av hydraulik för användning i hardware-in-the-loop
Modeling and simulation is growing ever more important in the development of new products. This thesis describes the use of Hopsan for hydraulic modeling and its use in conjunction with Simulink with the intent of using the model in a hardware-in-the-loop setup. A sensor layer has been created in Simulink to emulate all the internal sensors in a modern forklift. The details of using legacy C-code instead of a hardware MCU for a fully simulated environment, software-in-the-loop has been outlined. There are two major routes one can follow implementing software-in-the-loop, exporting the C-functions to CAPL via a export layer or creating an s-function in Simulink.
Föräldraledighetslagen som diskrimineringslag
The concept of sustainable development has been pervasive in recent years and many organizations choose to implement sustainability and adapt their activities accordingly. The purpose of this study have been to explore how a collaboration on the use of waste materials may look to analyze what influences cooperation. A case study has been carried out examining a Swedish state regional project aimed at creating partnerships between actors and utilizing textile waste with the help of design. The study was conducted using qualitative methods and the collection of data has been done through interviews and by examining documents. The results show that there are seven key factors that affect cooperation: expectations, commitment, internal communication, a strong non-profit actor, individual treatment, personal networks and the diversity of actors.
Headsetkommunikation för maskinbesättning : En kvalitativ studie om hur headsetkommunikation upplevs påverka personlig säkerhet och arbetseffektivitet för maskinbesättningen.
Detta är en kvalitativ intervjustudie som undersöker maskinpersonalens upplevelser av att använda headsetkommunikation i arbetet ombord. Totalt sex stycken maskinbesättningsmedlemmar intervjuades om deras upplevelser av hur headsetkommunikation har påverkat utförandet av arbetet, personlig säkerhet och tidseffektivitet. Resultaten som framkom av intervjuerna visar på att kommunikationen förbättrats med headsetkommunikation genom att talkommunikationen inte begränsas av höga bullernivåer vilket leder till minskad röstbelastning. De intervjuade vittnade om att den förbättrade kommunikationen underlättade i arbetet och ökade den personliga säkerheten genom att risken för missförstånd minskade samt att maskinbesättningens situationsmedvetenhet ökade. Förbättrad ergonomi vid svåra arbetsställningar i trånga utrymmen jämfört med handburna radioapparater upplevdes även det som en fördel med headsetkommunikation.
Konstruktion av infästning till dysa
The goal of this thesis is to design an attachment between a duct and a pod. A pod is what could be compared to an outboard engine for larger vessels. The pod is placed on the outside of the ship?s hull and can rotate 360 ?. A duct is a large steel ring that can be placed around the propeller on the pod to increasethe propulsion force of the ship in lower velocities.
