Användbar användarmedverkan : Är användarmedverkan positivt för systemutvecklingsprocessen?
Computer use at work has risen considerably over the past fifteen years and is currently a relatively common phenomenon when 76 percent of women and 72 percent of men using the computer in their daily work (SCB Arbetsmiljörapport 2009).According to Gulliksen and Göransson (2009), Sweden is one of the countries which are more advanced in the procurement of computer systems at work. He means that Sweden has unique opportunities and conditions for user participation in the development of computer systems, when the user has the right to influence their working environment through a law in the Work Environment Act. The paper examines the importance of user involvement in system development and the Swedish company's approach and experience of user involvement. To highlight and explore the importance of user involvement, there has been a case study in which users have been representative of the development process. The case study has been conducted on a case company where the system IST analys was in need of a new interface.
International Corporate Governance-A Comparison of the Corporate Governance Systems in Germany and Sweden
The purpose of the study is to investigate how much interest media has shown selected topics in the corporate governance systems in Germany and Sweden.

Processchemaläggare för mångkärniga processorer ? Fördelning av minnesbelastning i NUMA-system
For systems with multicore processors contention for shared resources is a problem that occurs when several memory-intensive processes are executed in parallel within the same memory domain. This contention has a direct influence on the performance of the system and is a complex problem that has been recognized for a long time. An attractive and actively studied way to minimize this problem is by using a process scheduler adapted to allocate processor cores in a way such that contention for shared resources is minimized.With the introduction of multicore NUMA-systems (Non-Uniform Memory Access) the situation has become even more complex. In these systems the access time for processor cores to different memory domains vary depending on factors such as distance and load. Thus, the process scheduler also has to consider where the memory of each process is placed to minimize the distance and balance the load on each memory domain.This report presents a user-level process scheduler for a NUMA-system based on the multicore processor Tilera TILEPro64.
En studie av rörelsen mot en processorienterad sjukvårdsorganisation - eller hur man får upp strutsar ur sanden
Health care costs in relation to GDP are escalating all over Europe and the Swedish health care industry is not an exception. Between 30 and 50 percent of resources used in health care are considered waste, in the sense that they don't contribute to increased health. This illustrates the big need for hospitals to become more efficient which is why many hospitals today are trying to move towards a process-oriented organization. This paper therefore aims to identify the elements necessary for this type of organizational change, the barriers encountered when moving from a functional to process oriented hospital as well as how to overcome them. The case study was conducted at Karolinska Universitetssjukhuset and shows the importance of not just transmitting a sense of urgency but also communicating that the upcoming change is long term.
Den särskilda kvinnan: En feministisk analys av Universella decimalklassifikationen
The aim of this thesis is to, from a feminist point of view, analyse the Universal Decimal Classification UDC, which is an international and widely used classification system. A number of the larger classification systems and subject heading lists have during the last decades been placed in the limelight of various gender studies and the systems treatment of women has been criticized. With this examination of the UDC, I dont merely wish to identify shortcomings and advantages with the UDCs way to treat men and women. The UDC is also used as an example of how the gender problem can be identified and interpretated in classification systems generally. My analysis is performed with a theoretical foundation in feminist science theories about knowledge and norms, together with a linguistic perspective on valuing and emotionally tinged language.
Simulering och cykeltidsberäkning av automatiserad produktionslina med hjälp av Process Simulate
Detta examensarbete har utförts i samarbete med Löfqvist Engineering i Örebro. Uppgiften har varit att utföra en simulering av en stor automatiserad produktionslina som ska användas vid tillverkning av avgassystem till lastbilar. Utifrån denna simulering skall exakta cykeltider för produktionen bestämmas. Dessa tider kan sedan användas av Löfqvist Engineering för att verifiera tidigare uppskattade tider.Arbetet inkluderar en litteraturstudie om Lean Production och hur det fungerar ihop med automation. Det finns även med lite bakgrundsinformation om Just In Time, olika filformat och robotsimulering i allmänhet för att ge en bättre överblick av ämnet.Programmet som har valts för att utföra simuleringen är Tecnomatix Process Simulate och den inbyggda Line Simulation modulen.
Aktiv bullerdämpning i ventilationssystem
Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.
Bonusregn över svenska storbanker : En studie om belöningssystemens utformande för legitimitet
The current financial crisis has left its mark. It has even hit the major Swedish banks who have shown large losses. The media has not been slow to take note of this, and the constant political debate about the bonus culture has been reinvigorated. Our aim is to find out how the major Swedish banks relate to the publicity and describe how and why senior executives are rewarded, and what strategies banks are using in the design of their reward system to maintain a legitimate behavior, and thus the confidence of its stakeholders.As a starting point to answer our purpose we have used the agency theory that describes our view of how various problems occurs and how incentives can be established in order to get senior executives to act for their owners' interests. Modern theories of reward systems are taken from a variety of authors, these theories give us an insight into how reward systems can be designed in banks.

För en kreativ arbetsplats: Kvinnor + Män = Sant - En fallstudie av Enea Systems AB
Syftet med vår undersökning är att ge förslag på vad ansvariga på mansdominerade företag bör tänka på vid utformningen av sin interna- och externa kommunikation samt hur dessa kan samverka då mansdominerade företag önskar attrahera fler kvinnliga medarbetare.Vi har valt att använda oss av relevanta teorier som kopplar samman marknadskommunikation (intern- och extern kommunikation), rekrytering (att attrahera) och mångfald (genus). Relevanta delar av dessa teorier har använts vid analys av vårt empiriska material.Vår empiri utgörs av intervjuer med sju medarbetare på Enea Systems AB samt observation av Enea Systems AB under arbetsmarknadsdagar på Lunds Tekniska Högskola. Slutsats: Det är viktigt att ha en förståelse för hur intern- och extern kommunikation hänger samman i ett system. Det som kommuniceras internt speglas även utåt. Det är därför viktigt att förstå hela flödet av kommunikation, som finns både internt och externt för att mansdominerade företag skall lyckas attrahera fler kvinnliga medarbetare.

????Att lösa reglertekniska problem med Modelica
Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.
