There is general consensus among road safety researchers that the crash count is not linear with respect to the traffic volume. However, the now-preferred practice of estimating exponents on traffic volume not only results in parameters that cannot be confidently applied in other contexts, but also offers very little insight into the relationship. This paper describes a preliminary investigation o
The question of how to lead a happy and meaningful life has been at the heart of philosophical debate since time immemorial. Today, however, these questions seem to be addressed not by philosophers but self-help gurus, who frantically champion the individual's quest for self-expression and self-realization; the desire to become authentic. Against these new age sophistries, How to Stop Living and S
In the spectral region 2400-3160A of Eta Carinae, we have identifiedapproximately 500 absorption lines each with up to twenty velocitycomponents.The -512 km/s component is truely unique as 1) the typicalline width is <3 km/s, 2) the identified lines are in Fe I, Fe II, VII and Ti II, and 3) the lines originate from lower levels up to 2000cm-1 above the ground level. We have measured the velocity c
Effects of the intrinsic electron spin-orbit interaction on transport and optical properties of III-V semiconductor quantum wells have been studied theoretically. It is shown that due to crystal anisotropy of this interaction, the weak localization magnetoresistance in a magnetic field parallel to interfaces is very sensitive to the epitaxy growth direction and also to the orientation of the magn
Vehicular networks will not be commercially deployed unless there are applications that benefit from them. Since the first research projects on vehicular networks, see, for example, the PROMETHEUS project [1,2], the main focus has been on increasing traffic safety. With the help of vehicular communication, the number of accidents will decrease and human lives will be saved. Therefore, the two appl
Wind speed and direction have a significant effect on a flying bird's ground speed. Migrants are therefore expected to be sensitive to wind conditions and this should have consequences for optimal strategies of stopover and refuelling. Based on an earlier model of time-minimizing migration which includes wind condition, we investigate the consequences of the temporal correlation of wind conditions
Anomaly detection is becoming a powerful and necessary component as wireless networks gain popularity. In this paper, we evaluate the efficacy of PCA based anomaly detection for wireless mesh networks (WMN). PCA based method [1] was originally developed for wired networks. Our experiments show that it is possible to detect different types of anomalies, such as Denial-of-service (DoS) attack, port
Since the Financial and Eurozone crisis that erupted in 2009/2010, Germany has seen the rise of a new populist radical right party; the Alternative für Deutschland (AfD). In the years after its establishment in 2013, this party has experienced many electoral successes and entered not only thirteen federal state parliaments, but also the European Parliament in 2014. This development is atypical for
Histopathology is the procedure used in medicine to optically examine microscope-images of tissue samples (biopsies) in order to study the manifestation of disease. It is used, for example, to diagnose the spread and type of cancer tumors, which have implications on the chosen treatment. Currently this type of analysis is done manually by trained professionals. It is time consuming and the diagnos
A method for investigating how the ocean surface aects the accuracy of Airborne Lidar Bathymetry surveys, (ALB), due to environmental conditions, was developed. Computer graphic techniques were examined and utilized for construction of realistic ocean surfaces. Wave spectrum models available in the literature describing the wave number composition of ocean surfaces were used in order to be able to
Serious Games – Integrating games in military training. Serious games are computer games used for various training in virtual environments. This can in many cases reduce costs, time and gain better results over ordinary training. Complex training scenarios which would be practically infeasible to create in reality can be constructed in a virtual environment. Saab Training Systems have developed an
GIS Section of Street and Park department of Malmö Municipality continuously receives new spatial data from different contractors that need to be saved to the GIS section traffic database. Due to spatial relationships and daily updates of traffic database, it is evident that the traffic database requires more consistency and integration in an automatic way. Since there is a spatial and conceptual
This thesis investigates the relationship between the human being and nature and how it emerges through the relationship between birdwatcher and bird. The aim is to study a potential contradiction in bird watching, between perceptual proximity and detached objectification that potentially inheres in the activity. Six birdwatchers are interviewed about their experiences of watching birds, in terms
Kriget i Bosnien och Hercegovina tog slut för 15 år sedan. Daytonavtalet reglerar villkoren för fredsbyggandet i landet. Annex 4 i Daytonavtalet består av Bosniens konstitution. Konstitutionen innefattar flera aspekter av maktdelning mellan de tre konstituerande folken, bosniaker, kroater och serber. Bosnien är således en stat som styrs enligt en konsociationell modell. Daytonavtalet utser en hög The war in Bosnia and Herzegovina ended 15 years ago. The General Framework Agreement for Peace in Bosnia and Herzegovina, commonly known as the Dayton Peace Agreement, stipulates the conditions for the peacebuilding process in the country. Annex 4 of the Dayton Peace Agreement comprises the constitution of Bosnia and Herzegovina. The constitution includes several aspects of power sharing among th
This thesis investigates the game of oil shipping; both the market settings and how the players play the game. An important characteristic of the oil shipping market is cycles in the spot freight prices. The cycles are created by the imperfect adjustment mechanisms of supply within the relatively short run, and by that the demand is not perfectly predictable. By a mathematical investigation, I sho
This study aims at examining and analyzing the involvement of the school counselor in the drug prevention work which is carried out in primary schools. This by examining how the work with drug prevention is carried out in some primary schools today, if there is a special focus on the defined risk student, and which approaches of the work is evidence based. We chose qualitative semi structured inte
Gröna tak kan minska problem med s.k. urban heat islands och kan användas för dagvattenhantering. Andra miljöfördelar som en förbättring av luftkvalitet, biodiversitet och bullerminskning finns också. Detta projekt fokuserar på lokala (kommunala) medel för att skapa en bättre miljö med extensiva gröna tak, vilka är nästan underhållsfria. Ett delområde i Lund som inkluderar Universitetet och UniverGreen roofs have the potential to mitigate problems with an urban heat island and to act as an element in stormwater management. Other environmental benefits exist as well, such as improvement of air quality, biological diversity and noise reduction. This project focuses on local community efforts to create a better environment through the use of extensive green roofs, which require almost no main
Hals- och huvudregionen innehåller många luftkaviteter t.ex. luftstrupe, bihålor och munhåla. Detta arbete undersökte vad som händer i vävnaden kring dessa luftkaviteter när de blir bestrålade med fotoner och hur bra ett dosplaneringssystem för strålbehandling modellerar den absorberade dosen till ett heterogent medium. Dosberäkningarna gjordes med hjälp av ett Monte Carlo-simuleringsprogram somPurpose: To study the build-down and build up of the absorbed dose at the interface between air and tissue in the head and neck region. Monte Carlo simulations are compared to a treatment planning system that is used at the University Hospital in Lund. Materials and methods A virtual phantom was constructed to resemble an air cavity in the head and neck region. The phantom consisted of a water cyl
