Abstract in UndeterminedEye movements provide an online measure of the strategies students use to solve a problem. Such strategies are difficult to investigate with traditional methods of assessment. In this paper, we present some background and highlights of work in progress, aiming at a largerstudy where we will investigate how engineering students solve problems in vector calculus.
In July 2000 the five-year Swedish national “Socware Research & Education Program” was started. One of the aims of the program was to develop an innovative unique educational curriculum in System-on-Chip design. The program was targeted at undergraduate and graduate. In total the program received USD $15 million funding. In 2005 the program entered a new phase; more than 500 Master’s students
Frequency modulation in ring VCOs is investigated. Primarily, the linearity of conversion from input voltage to output frequency is considered. Bulk-voltage control of the threshold voltage of the VCO transistors is found to be a very promising approach for applications in frequency /spl Delta//spl Sigma/ converters. Different approaches apply in presence of high supply voltages, when transistors
Popular Abstract in Swedish Trots ny fordonsteknik så har koldioxidutsläppen ökat med nästan 40% i Europa sedan 1990-talet. Detta beror främst på en tilltagande transport på våra vägar. Drivmedel som används inom transportsektorn är nästan uteslutande diesel och bensin, vilka härstammar från fossila bränslen. För att hantera konsekvenserna av transportfordons miljöpåverkan så blir lagstiftningen pThis thesis deals with large eddy simulations (LES) of turbulent combustion processes in direct injection internal combustion (IC) engines. Modeling of direct injection IC engine combustion involves modeling of turbulent spray/gas two-phase flow, modeling of chemical reactions of large hydrocarbon fuels and coupling of chemistry with turbulent flows. LES is chosen in this thesis for it capability
The Charcot-Leyden crystal (CLC) protein with lysophospholipase activity and carbohydrate-binding properties is a characteristic constituent of eosinophils and basophils. We investigated its subcellular distribution using immunoelectron microscopy. Eosinophil progenitors, mature eosinophils and basophils all contained CLC protein in their cytosol and in the euchromatin of the nucleus. A minor popu
Abstract: Over the past decade, a new global regime of anti-corruption has taken shape. Pushed by NGOs such as Transparency International, and with coalitions of international organizations, Western governments, and private business circles, we now have a framework of conventions and regulations that impel governments and international firms to act with integrity and to prevent corruption in busin
Tubes fabricated from dilute Zr-alloys serve as miniature pressure vessels in Pressurized Heavy Water Reactors and are subjected to stress, aqueous corrosion and intense irradiation during service. Hydrogen evolved during the corrosion reaction may enter into the material and precipitate as hydride phase, which acquire platelet shaped morphology in Zr-alloys and are known to embrittle the host mat
