Many specific and precise methods that support the mechanical engineering designer's work during the conceptual design phase exist, while only a few general methods address the embodiment design and detail design phases. Our study presents the pattern of the designer's problem-solving activity during the later phases of the design process. This model is in-tended to serve as a basis for further de
Since gaining independence in 1965, Singapore has become the most trade-intensive economy in the world and the richest country in Southeast Asia. This transformation has been accompanied by the emergence of a deep generational divide. More complex than simple disparities of education or changes in income and consumption patterns, this growing gulf encompasses language, religion, and social memory.
Popular Abstract in Swedish Studien handlar om en konflikt kring en muslimsk friskola i Jönköping. Utifrån fältarbete på den muslimska friskolan och en ordinarie grundskola i kommunen, femton intervjuer och ett omfattande tidningsmaterial har jag problematiserat relationen mellan olika grupper i samhället och vem som har tolkningsföreträde i frågor om skola, fostran och värderingar. De muslimska fThe study is about a conflict concerning a Muslim Independent School in Jönköping. Based on fieldwork carried out on the Muslim Independent School and one of the local authority´s comprehensive schools - which included fifteen interviews and a comprehensive collection of newspaper articles and reports - I have problemised the relationship between the different groups in the local community and who
A dual band antenna for two ISM bands at 2.4 GHz and 5 GHz has been evaluated. The antenna structure derives its advantage by deploying several radiators as fingers spreading from a single feeding point. Each radiator functions as both a half-wave and a quarter-wave radiator. Arranging them in parallel matches the half-wave resonance to 50 W. By carefully selecting the angle to ground plane and us
Fuel cells (FCs) are promising for future energy systems, since they are energy efficient and fuel can be produced locally. When hydrogen is used as fuel, there are no emissions of greenhouse gases. In this study a two dimensional CFD (COMSOL Multiphysics) is employed to study the effect from porous material surface area ratio on reforming reaction rates and gas species distributions for an anode-
Popular Abstract in Swedish Växter är en av den största grupperna av organismer på jorden. Den här gruppen av organismer kan syntesisera kolhydrater med solenergi. I växter används en stor del av kolhydraterna till att bilda förnyelsebara polysackarider som sedan används för att bygga upp vedstrukturer. Den mest kända växtpolysackariden är cellulosa som består av långa kedjor av glukos. Den näst mHemicellulose is the second most abundant group of renewable polysaccharides. Mannans can be found as the major hemicellulose in softwood and as storage polysaccharides in a range of plants. In this work, structural and functional characterisations of family 5 and 26 endo-1,4-b-mannanases (b-mannanases) have been performed. These families belong to the large and diverse glycoside hydrolase clan A,
Climate change and disasters are among today’s most pressing issues. The damage caused by the world-wide increase in disasters is staggering, with the urban poor being most at risk. Disasters make their al-ready precarious living conditions worse, creating a vicious circle of poverty. More and more attention has thus been given to the need to address changing climatic conditions and disaster risk
Stress corrosion, SC, in some cases gives rise to stress corrosion cracking, SCC, which differs from purely stress intensity driven cracks in many aspects. They initiate and grow under the influence of an aggressive environment in a stressed substrate. They grow at low load and may branch. The phenomenon of SCC is very complex, both the initiation phase and crack extension itself of SCC is seeming
