An alternative optimization technique for JavaScript engines

Thread Level Speculation at function level has been suggested as a method to automatically (or semi-automatically) extract parallelism from sequential programs. While there have been multiple implementations in both hardware and software, little work has been done in the context of dynamic programming languages such as JavaScript. In this paper we evaluate the effects of a simple Thread Level Spec

Physical limitations on broadband scattering

In this paper, physical limitations on broadband scattering are presented for heterogeneous anisotropic scatterers of arbitrary shape. A measure of broadband scattering in terms of the extinction cross section is derived based on the holomorphic properties of the forward scattering dyadic. An isoperimetric bound for isotropic material parameters is presented and ellipsoidal scatterers are discusse

Lärare skriver – för att förbättra lärande och undervisning

Vid medicinska fakulteten i Lund forskar man inte bara inom medicin, det forskas även om lärande och undervisning. Vi har intresserat oss för denna utbildningsvetenskapliga forskning och velat ta reda på vad den handlar om, hur den relaterar till fakultetens utbildningsverksamhet, samt varför den har genomförts. Särskilt har vi undrat om forskningen är att betrakta som SoTL, dvs Scholarship of Tea

A Look at the Roles of Look & Roles in Embodied Pedagogical Agents - A User Preference Perspective

. The paper presents a theoretical framework addressing three aspects of embodied pedagogical agents: visual static appearance, pedagogical role, and communicative style. The framework is then applied to a user study where 90 school children (age 12 15) in a dummy multimedia program were presented with either an instructor or a learning companion condition. They were then to choose between eight v
