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
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
This paper examines the increasingly integrated relationship between art and fashion through the case of the collaboration of the Japanese artist Takashi Murakami and the luxury brand Louis Vuitton.
. 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
Three mm-wave pulse generation circuits fabricated in a standard 65nm CMOS process are presented. Two versions are based on the cross-coupled NMOS LC-VCO (500um × 300 um), and one is based on the Colpitts VCO (600um × 300 um). No additional buffers are used in the cross-coupled versions, as they are directly loaded by 50 Ohms through a balun. They can produce measured pulses exceeding 8dBm peak ou
