This research uses data from observations of 8277 motorcyclists at various types of roads of the road hierarchy in Malaysia in 2015, to investigate the effects of road characteristics, motorcyclists’ riding behaviour, motorcyclists’ and motorcycles’ characteristics on the occurrence of riding with excessive speed. For data collection and analysis, new software, i.e. MECHROM, was developed. The spe
Ethics is increasingly recognized as one of several important dimensions of performance. Yet, performance audit, or value-for-money audit, as conducted by supreme audit institutions (SAIs), does not typically include this dimension.

Multi-component transient signals show up in many different areas, most commonly in communication and radar but are also often found in measurements of human related signals, such as electrical responses of the heart and the brain. Transient signals are also typical in animal acoustic applications, e.g., dolphin echo locations and bird song syllables. The usual basis functions in linear modeling o
Main Abstract Content: Purpose To investigate the association between conflict frequency and bullying at T1 and T2, moderation of individual conflict management styles and mediation of negative acts. Methodology Data from the Workplace Bullying and Harassment cohort (2006-2008) were analysed cross-sectionally (n=3363) and longitudinally (n=1664). Measures: conflict frequency; three individual co
Popular Abstract in Swedish 75% av alla kemiska reaktioner sker på en yta av något slag. En av anledningarna till detta är att många ytor har en katalytisk effekt. Inom kemins värld är en katalysator något som påskyndar en kemisk reaktion utan att själv förbrukas, och ett tydligt exempel på en katalytiskt aktiv yta är en bilkatalysator, vilken i princip består av en varm metallyta. På denna yta omThis work deals with interpretation of experimental surface spectroscopic data with the aid of first-principle calculations. Surface infrared reflection-absorption spectra as well as spectra from the electron spectroscopic methods photoemission and X-ray absorption are considered. In all cases the surface is modeled by a metal cluster with the same (frozen) geometry as part of the surface. The wo
Abstract in Undetermined Applications of physical bounds for electromagnetic radiators can be used to derive a priori estimates for antenna parameters in terms of the directivity-bandwidth product. These estimates relate the static electric and magnetic polarizability of the radiating structure to its dynamic properties.

Popular Abstract in English News about global warming, discussions about alternative fuels such as natural-gas and biogas, and commercials about gas engines sound familiar to the most people living in modern societies. Why global warming is important? What is the role of natural-gas engines in this subject? Are natural-gas engines efficient? Do they perform as well as diesel engines? If not, why? Most heavy-duty engines are diesel operated. Severe emission regulations, high fuel prices, high technology costs (e.g. catalysts, fuel injection systems) and unsustainably in supplying fuel are enough reasons to convenience engine developers to explore alternative technologies or fuels. Using natural gas/biogas can be a very good alternative due to the attractive fuel properties regarding emissio

The real estate and construction sector is a major contributor to climate change, which presents opportunities for significant impact from the implementation of sustainable measures. Circular economy is a sustainability concept which has increased in popularity both in academia and in industry in the last decade. To date the focus in the field of circular economy in the built environment has been
A class of plane stress problems for incompressible materials is studied. The class concerns problems for unidirectionally reinforced thin sheets under quasi-static loading conditions. An incremental theory of plasticity and an isotropic yield condition is assumed. It is demonstrated how a corresponding antiplane strain problem can be identified, Thus solutions are readily found to a variety of prA class of plane stress problems for incompressible materials is studied.

Popular Abstract in English Imagine you are sunbathing on a sandy beach, while reading the latest Dan Brown book. Once the book is finished, you look at the waves and notice that in one place, they decelerate and become large. Excited by your reading, you imagine that beneath those larger waves there is a ship containing a treasure in it (most likely sunk by the Illuminati during World War II). BuThis thesis describes how photoemission stimulated by an attosecond pulse train (APT) can be used to extract information on electron correlation in simple quantum systems such as atoms. The emission of the electron by an APT induces a reorganization of the electrons remaining in the ion core. This reorganization causes a change in the trajectory of the emitted electron. An infrared (IR) field is u
Popular Abstract in Swedish Mycket få människor omkring oss vet innebörden av ordet kavitation, förutom de som såg filmen "The Hunt for Red October" och kan relatera kavitation till Sean Connery i en ubåt. Kavitation motsvarar bildandet av bubblor, som kan likna kokande vatten i en kastrull. Men den uppstår inte på grund av en hög temperatur utan på grund av ett lågt tryck. Den finns i de flesta tVery few people around us know the meaning of the word cavitation, except from those who saw the movie "The Hunt for Red October" and can relate cavitation to Sean Connery in a submarine. Some of them know that it corresponds to the formation of bubbles, due to a pressure drop, and causes erosion and noise. However, cavitation is much more complex. A large amount of research work has been done ove
Syftet med studien var att undersöka om patienter som erhåller specialiserad palliativ hemsjukvård (SPH) får bättre palliativ vård, med färre besök på akutmottagning och vårddagar på sjukhus samt i högre utsträckning kan dö i sitt eget hem jämfört med de patienter som inte ansluts till SPH. Vi ville även undersöka om SPH är kostnadsbesparande.Genom retrospektiv journalgenomgång inkluderades de 150
Popular Abstract in English In the past ten years, homogeneous charge compression ignition (HCCI) combustion has been one of the subjects receiving great research interests in the combustion research community and the engine industry. This is because HCCI combustion processes have the potential of not only capable providing high efficiency like diesel engine combustion, but also producing much lowLarge Eddy Simulation (LES) modeling is developed to study homogeneous charge compression ignition (HCCI) combustion under different engine operation and mixture conditions, including real engine configurations and generic test cases. A previously developed HCCI model has been validated by comparing the simulation results with engine experiments. A new spark-assisted HCCI (SACI) combustion model h
Popular Abstract in Swedish Förblandad förbränning har sedan lång tid tillbaka varit en av grundbultarna i industriellt applicerad förbränning såsom i bensinmotorer och gasturbiner. Genom att direkt kunna kontrollera blandningsförhållandet mellan bränsle och luft kan utsläppen av skadliga ämnen hållas på en minimal nivå. Detta gör förblandad förbränning mycket attraktiv. För att industriellt appliIn generally accepted and applied flamelet combustion models, a turbulent flame is mainly assumed distorted by the large-scale turbulence eddies, whereas small-scale turbulence effects on the local flamelet structures are neglected. However, in a lot of industrial applications rather high turbulent intensities are often imposed, which induce turbulence scales at ranges smaller than the flame thick
Under vilka förutsättningar kan ett effektivt samarbete komma till stånd vid humanitära insatser? Den omfattande jordbävningen i Pakistan 2005 kallade till sig ett stort antal aktörer, däribland Röda Korset, Oxfam och CARE, alla NGOs inriktade på humanitära insatser, samt FN och den pakistanska staten. Vi framlägger i vår studie teorin att ett effektivt samarbete främst kan komma till stånd om de
