A crack model that considers general normal and shear loading is proposed. It involves elasticity, plasticity and damage and it is thermodynamically based. An essential feature of the model is its consistency with the concepts behind the fictitious crack model.
An upper bound on the effective area and bandwidth product for linearly polarized array antennas is derived. The bound is based on the forward scattering sum rule that relates the antenna properties with the polarizability of the antenna structure. The results are illustrated for a dipole array and a capacitively loaded dipole array with numerical simulations.
Regeln för subjekt-verbkongruens i engelskan anses vara enkel, både att förstå och förklara. Ändå gör L2-inlärare överraskande ofta fel, vilket ständigt påpekas av lärare i skolan och på högskolenivå. Därför har vi undersökt om källan till inlärarnas bristande förmåga är 1) ofullständig kunskap om regeln för subjekt-verbkongruens (d.v.s. explicit kunskap), eller 2) inlärarnas oförmåga att tillämpa
The development of a predictive control algorithm for glycaemia regulation in diabetic subjects requires patient-specific models of the glucose metabolism which are physiologically relevant, parsimonious, yet able to accurately forecast blood glucose. Given the measured data: total plasma insulin [mIU/L]; plasma glucose [mg/dL]; plasma glucose rate of appearance after intestinal absorption [mg/kg
Monolithic class-D audio amplifiers typically feature built-in over current protection circuitry that shuts down the amplifier in case of a short circuit on the output speaker terminals. To minimize cost, the threshold at which the device shuts down must be set just above the maximum current that can flow in the loudspeaker during normal operation. The current required is determined by the complex

As people and countries around the world wrestle with options to reduce greenhouse gas (GHG) emissions, mitigation efforts must accelerate faster than ever if we want to stabilize the concentration of GHG emissions at 450 ppm CO2-eq. Economic incentives for achieving this stabilisation target have received much attention. However, the effectiveness and efficiency of such measures depends on numero
