Over the recent years there has been a large development of various driver support systems with the intention to improve traffic safety. For these systems to be successful in reducing fatalities and trauma it is decisive that they are used by the drivers. Hence, the driver’s acceptance of the systems is vital. How acceptance can be measured depends on how it is defined. Unfortunately, there is no

Starting with the assumption that perception is not merely a reaction to outside stimulation but a process of creation, although mostly brief and inaccessible to conscious retrieval, the present paper attempts to determine the prerequisites of a stable and secure accout of reality. The authors’ leading hypothesis is that a dependable end product of adaptive and constructive processes is contingent

This paper introduces a novel transmission technique for MIMO broadcasting directional channels, herein called the Angle-of-Departure-Aided Opportunistic Space-Division Multiple Access (AOD-OSDMA) technique. In AOD-OSDMA, the knowledge of angles-of-departure (AODs) at the BS of the strongest signal received by each user is used to design multiple opportunistic beams so that advantage is made of th

Both Canada and Germany are multi-cultural societies, but with different approaches to this reality. In this chapter, I explore the question of how young people understand and define their social positions, and how much the process is influenced by the societies they live in. I use material from a qualitative research project in one German and one Canadian secondary school. Young people with and w

Manufacturing involute gears using form grinding or form milling wheels are beneficial to hobs in some special cases, such as small scale production and, the obvious, manufacture of internal gears. To manufacture involute gears correctly the form wheel must be purpose designed, and in this paper the geometry of the form wheel is determined through inverse calculation. A mathematical model is prese

Popular Abstract in Swedish Elektrostatiske vekselvirkninger mellem biomolekyler er vigtige, ikke bare i biologiske systemer, men også i flere tekniske sammenhænge. I denne afhandling studereres en række forskellige egenskaber, relevant for særligt proteiner. Således har vi ved hjælp af molekylær simulering undersøgt hvorledes proteiner vekselvirker med protoner, salte, andre peptider og proteiner

LGBT rights has become an increasingly important part of the EU’s founding values. Yet, large discrepancies exist within the Union regarding the protection of sexual minorities. Using the Europeanization theories of external incentives and social learning, this paper seeks to assess what impact the European Union has on the implementation of LGBT rights during the accession process. By contrasting

Kandidatuppsatsen Hållbarhet inom livsmedelsbranschen är en uppsats på C-nivå vid Lunds universitet. Arbetet svarar dels på hur producerande livsmedelsföretag med säte i Skåne ser på sitt arbete med hållbarhet. Dels kartläggs de skillnader, och likheter, som livsmedelsföretagen har av sitt praktiska hållbarhetsarbete gentemot den teori som forskningsfronten arbetat fram. Avslutningsvis summeras skDue to the historical developments within human society that concern various forms of production, especially food production, sustainability has become an important issue. This Bachelors Essay strives to illuminate the differences between what academic knowledge claims should be done about sustainability, and how small to medium food producers perceive their daily efforts in relation to the three

The purpose of this study is to investigate what determines an individual to join the firm and how the membership in the firm affects the individual and his identity. This study is based on the interviews with six members of a football firm in Sweden. The selection of firm members to participate in this study was made based on the writers contacts within the firm. The results of this study shows t

The purpose of this thesis is to examine and compare the effect of institutional quality on the economic growth rate in developed and developing countries. To do this panel data was examined using a pooled regression model and a fixed effects model. Three institutional variables from Freedom House, the International Country Risk Guide and the Database of Political Institutions were used. The resul

Relativistic channels are generated in an under-dense plasma by means of subpicosecond laser pulses. The channel extension is characterized via the Thomson-scattered light and the impact of the laser pulse duration and chirp are studied. It is shown that, under certain conditions, the channel extends further when the pulse duration is increased. This is in contrast to many earlier reports, where t

Many fish and some terrestrial animals have multifocal lenses that compensate for chromatic aberration by a mechanism unique to biological optical systems. We describe four optical methods for the study of such lenses. Significantly improved methods (focal-area imaging, schlieren photography, and laser scanning) are explained in full detail. One method (photorefractometry) was only slightly modifi
