People who have visual impairments may have difficulties navigating freely and without personal assistance, and some are even afraid to go out alone. Current navigation devices with non-visual feedback are quite expensive, few, and are in general focused on routing and target finding. We have developed a test prototype application for Android in which a user may scan for map information using the
he regional coastal evolution model Cascade was enhanced to better describe the transfer and storage of sediment. Focus was on the cross-shore exchange of material from the subaerial to the sub-aqueous portion of the beach and on shoal evolution at coastal inlets. Cross-shore material exchange now includes erosion due to wave impact and overwash, and barrier and dune build-up by wind. Cascade was
Följande är en pedagogisk utvecklingsplan för intermediala kulturstudier, delkurs tre av fyra på grundnivåutbildningen intermediala studier (IMS A11, 30 hp). Kursen ges fr.o.m. hösten 2009 även som fristående kurs på 7,5 hp (IMS A40), tillsammans med helterminsstudenterna och utan förkunskapskrav. Med detta uppstår ett pedagogiskt problem, då delkursen föregrips av två andra delkurser: intermedial
Projektet redovisas med en beskrivning och analys av arbetet med att leda ett lärarlag som här definieras som ett community of practice (Etienne Wenger 1988) med målet att genom ett sådant kollegiearbete gemensamt utveckla ett ändamålsenligt campus ethos för våra masterstudenter (Adrianna Kezar 2007). Mina erfarenheter och reflektioner kring arbetet med att leda och skapa möjligheter för samarbete
Image processing is one of the popular applications of Cellular Neural Networks. Macro enriched field-programmable gate-arrays can be used to realize such systems on silicon. The paper discusses a pipelined implementation that supports the handling of gray-level images at 180 to 240 Mpixels per second by exploiting the Virtex-II macros to spatially unroll the local feedback.
Nonlinear axisymmetric finite element analyses are performed on the uniaxial compressive test of concrete cylinders. The models include thick steel loading plates, and cylinders with height-to-diameter ratios (h/d) ranging from 1–3 are treated. A simple constitutive model of the concrete is employed, which accounts for the strain hardening and softening in the pre- and postfailure regions, respect
