Stadsdelsförnyelse på Öster i Gävle : En analys av fysiska faktorer för en bättre boendemiljö
Nearly 50 years after the building of the first million programme neighbourhoods many Swedish municipalities faces an extensive restoration work in these neighbourhoods which during their relatively short lifetime have acted as a target for a large amount of criticism. Öster in Gävle is a million programme neighbourhood that has gone through an extensive restoration between 2001-2009 with the aim of improving the living environment. Improvements have been made in the outdoor environment, to the facades of the houses and the entrances? of each building. The purpose of this study has been to investigate the effects of the renewal in the physical outdoor environment for those who live in the neighbourhood.
Att skilja äpplen från päron : en studie om belöningssystem
Companies today need to be more focused than ever on having an active Human Resource Management culture. This is not only because of the companies? concern for their staffs wellbeing, but for the companies? effectiveness in the long run. The reward systems which many corporations use today, to both keep their employees and attract new ones, is a well researched subject by scholars as well as journalists. Earlier research has suggested that it is important to implement an active Human Resource Strategy.
Automatisk trimning av drivsystemreglering från MATLAB
This master thesis covers the development of an automatic tuning process for the existing speed controller for drive systems. The drive systems are resonant two-mass systems where a motor is used to drive a load connected by a shaft. The developed method relies heavily on system identification and the construction of a complete mechanical model of the process. With this approach, the common problem with poor load speed control that derives from measuring only the motor speed can be addressed and solved for a majority of such processes.The automatic tuning method has along with general test functions been implemented in a complete tool for automatic tuning, testing and performance evaluation and reporting for drive systems..
Webbens klassifikationssystem. En komparativ studie
This thesis deals with subject-based hierarchical search-services on the World Wide Web. The purpose is to investigate how systems of this kind facilitate information retrieval through subject-based information seeking. Its starting point is taken from the study of texts and qualitative analyses of search-services on the World Wide Web. Important aspects and features of the Internet and the World Wide Web are explained as well. Three systems are examined: Mölndals Stadsbiblioteks Länkkatalog, Svesök, and Alta Vista.
Sjuksköterskors uppfattning av elektronisk dokumentation avseende tidsåtgång, teknik och vårdkvalitet
Documentation in electronic journals is perceived as time consuming and sometimes technically difficult to handle, but also leads to an improved quality of care. Objective: The purpose of this study was to investigate nurses' perceptions of documentation with a focus on timing, technique and quality of care and whether any differences in these perceptions were dependent on age. Method: Quantitative descriptive cross-sectional study in the survey form, 28 nurses at a university hospital in central Sweden participated in the study. Regression analysis was performed with Spearman's rank correlation coefficient. Results: Electronic documentation takes 30 to 60 minutes for most nurses and half of them considered it a reasonable time.
Dammsäkerhetsanalys via stabilitetsberäkningar för Långströmmens kraftverk : En jämförelse mellan olika dimensioneringsmetoder
A detailed dam safety evaluation (in Sweden called FDU) was performed in 2009 by WSP where stability control was performed for Långströmmen power plant with associated spillways. This evaluation concluded that stability could not be ensured, and risk of sliding occurred. The evaluation is based entirely on the recommendations outlined in RIDAS, the power companies guidelines for dam safety, and it is clear that extensive renovations are necessary to stabilize the dam.In this work, the stability will also be checked with guidance through new proposals on guidelines for concrete dams sliding stability, ELFORSK?s report 08:59. This report considered the guidelines in RIDAS as oversimplified, both from an international perspective, but also with regard to the current state of knowledge regarding dam safety.
XML som informationsbärare för EDI
Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used.
Deriving ECA-rules from timed-automata specifications.
Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.
Diskussioner om trygghet i planeringssammanhang :
This is a bachelor?s essay in the landscape architect programme in Alnarp.
The purpose of the essay is to describe discussions about security in planning contexts in Sweden. Written material from three levels of the discussions has been studied: Swedish research, governmental directives and practisers. I have tried to obtain a variation in types of material.
Värdepremium på den svenska marknaden - En residualvinstvärdering med säkerhetsmarginal
This paper attempts to investigate the correlation of 12 month abnormal returns and the fundamental value of stocks in theSwedish stock market between the year 2000-2011. Also, the paper tries to apply and evaluate the concept of the margin ofsafety. In estimating the fundamental value we use the residual income valuation model and three different estimationapproaches of the beta coefficient in order to correct for financial and operational biases. We find that our different portfoliosearn abnormal returns. However, this could be explained by the size effect and P/B effect.
Alternativ för värme- och kylaförsörjning i planerade kontorsbyggnader på Arlanda
This thesis consider alternatives for heating and cooling planned office buildings at Arlanda airport. The thesis is divided into three parts where the third part is a shorter synthesis of the two first. In the first part the energy demands of the buildings are modelled in a computer program. Two different building models are created, one more conventional and one with good energy properties. The results shows that with proper construction and ventilation systems etc.
Vad kostar deltid? Kvinnors deltidsarbete ur ett pensionsperspektiv
Mothers of small children often work part-time in Sweden. Since old age pensions are based on lifetime income, part-time work leads to lower pensions, as long as there is no compensation from non-actuarial benefits such as minimum pensions. In this paper, I investigate whether different components of the Swedish pension system provide incentives for part-time work among women. The analysis is performed through a simulation of future pensions for 9 typical women in a certain cohort. For three levels of education, I compare pensions of women with different labor market participation rates in different growth scenarios.
Våga fråga: Faktorer som påverkar psykologisk trygghet i team
This thesis aims to further study the interpersonal risk taking within groups and thereby the importance of a climate promoting a reflective behavior. The increased demand in complexity and exposure towards teamwork leads to increased call for knowledge integration, which can be explained as the ability to integrate the collective knowledge within the group. We have therefor identified a need for better understanding what makes a group more effective. Key factors for self-estimated effective collaboration have been shown to be a group's reflective behavior and ability to coordinate the skills that each individual possesses. These factors are greatly affected by the psychological safety within the team.
Hantering av informationssystem
Lund who has over 90 systems in 12 departments and now wants to streamline the management of these IT systems. Governance of IT systems is something that Lund would treat as it carried a large amount of changes in their practices, where the control is something missed in trying to standardize their systems. What's missing for Lund Municipality is routine to fall back on in order to streamline the management when they get into these complex situations.Given that Lund treat so many systems make it so that the situation quickly becomes very complex due of the organization's structure. The municipality is divided into twelve departments that have their own goals, it is an organization that is organized, which makes creating standards become complicated when all departments have different needs. Our study was based on a framework that deals with complex environments that lack a clear definition.An analysis was conducted where we started from the theory associated with the interviews conducted in which we aimed to understand their decision and understand the processes that affect system development.
Riskhantering av kritiska infrastrukturtjänster : En studie av Apotekens Service ur ett HRO-perspektiv
Risk management has become a key ingredient for businesses all over the world. High Reliability Organizations (HRO) has distinguished themselves as experts in this area. By continuously focusing on improving their ability to manage risks they?ve been able to successfully avoid catastrophes in environments where normal accidents can be expected due to complexity and risk factors.The aim of the thesis is to improve the risk management at Apotekens Service by applying theories from HRO and safety culture. In July 2009, following the re-regulation of the Swedish pharmacy market, Apotekens Service AB was appointed national pharmacy infrastructure supplier for the Swedish health care system.
