Popular Abstract in Swedish I många tekniska applikationer vill man på något sätt överföra elektrisk energi till mekanisk energi eller tvärtom. Det kan till exempel handla om att med hjälp av en elektrisk signal generera eller mäta rörelse. Så kallade elektroaktiva material har den speciella egenskapen att överföringen mellan elektrisk och mekanisk energi sker direkt. I ett piezoelektriskt materiaThe electroactive polymer materials considered in this work react to electric stimuli by producing deformations. In some cases, the electrically induced deformations are moderate, while in other cases they can be very large and the specimen is stretched to more than twice its original length. The latter response is seen in so called dielectric elastomer actuators (DEA). The possibility of very lar

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

Popular Abstract in English Popular scientific summary Interest in food and plants as sources of antioxidants has increased in recent years, since antioxidants are believed to have major health benefits. Food and plants have complex matrices made up of different compounds (polyphenols, antocyanidin, carotenoids, etc) that individually or jointly can act as antioxidants. Polyphenols and anthocyaniAbstract The constant need to improve health and to prevent disease in Bolivia, especially in the Andean region with its extreme environmental conditions (high altitude and lower temperatures), motivated us to extend studies of antioxidant sources in foods and plants, since antioxidants are believed to have major health benefits. Spectrophotometric methods, such as ABTS (2, 2’- azinobis-3-ethyl

This paper focuses on propagation of transient electromagnetic waves in waveguides of general cross section with perfectly conducting walls. The solution of the transient wave propagation problem relies on a wave splitting technique, which has been frequently used in direct and inverse scattering problems during the last decade. The field in the waveguide is represented as a time convolution of a
