We study the nonexistence of global weak solutions to following semi-linear Moore - Gibson-Thompson equation with nonlinearity derivative type, namely,$$\left\{\begin{array}{l}u_{ttt}+u_{tt}-\Delta u-(-\Delta )^{\frac{\alpha}{2}}u_{t}=|u_t|^p,\quad x\in \R^n,\quad t>0,\\u(0,x)= u_0(x),\quad u_t(0,x)=u_1(x), \quad u_{tt}(0,x)= u_2(x) \R^n,\end{array}\right.$$where $\alpha\in (0, 2],\quad ...

A generalization of vector fields, referred to as N -direction fields or cross fields when N = 4, has been recently introduced and studied for geometry processing, with applications in quadrilateral (quad) meshing, texture mapping, and parameterization. We make the observation that cross field design for two-dimensional quad meshing is related to the well-known GinzburgLandau problem from mathe...

We formalize a combinatorial principle, called the 3XOR principle, due to Feige, Kim and Ofek [14], as a family of unsatisfiable propositional formulas for which refutations of small size in any propositional proof system that possesses the feasible interpolation property imply an efficient deterministic refutation algorithm for random 3SAT with n variables and Ω(n) clauses. Such small size ref...

A novel large input range source-follower based bi-quad filter cell is proposed offering an additional degree of freedom to the position of the poles and zeros. Simulation results of a 4th order fully differential elliptical filter in a 0.13μm CMOS technology confirm a power consumption of 160μA @ 1.2V, an IIP3 of 6.3 dBm and a steepness of 177 db/decade.

Newborns with peripheral nerve lesions involving the upper extremity are difficult to evaluate. The reliability of the Active Movement Scale (AMS), a tool for assessing motor function in infants with obstetrical brachial plexus palsy (OBPP), was examined in 2 complementary studies. Part A was an interrater reliability study in which 63 infants younger than 1 year with OBPP were independently ev...

In this work we study the question of how much data is required in order for classical X and X charts with estimated control limits to perform essentially like charts with the true control limits. The results indicate that using estimated control limits results in charts on which the events that individual points exceed control limits are dependent events, and that one result of this dependence...

Application of low-cost commercial plastic encapsulated microcircuits (PEMs) for military and aerospace applications requires rigorous analysis of their quality and reliability in harsh environments. It is known that degradation of Au/Al wire bonds limits reliability of PEMs at high temperatures; however, there is only limited information on acceleration factors of wire-bond failures. In this w...

Zusammenfassung Das DFN-Projekt QUASAR untersucht Quality-of-ServiceArchitekturen für das DFN G-WiN. In enger Kooperation mit anderen europäischen Forschungsnetzbetreibern wurde im Rahmen des IST Projektes SEQUIN hierzu ein Premium IP Dienst entwickelt, der im pan-europäischen Backbone GÉANT implementiert und in ersten Feldversuchen erprobt wurde. In diesem Beitrag werden die Grundzüge des Prem...

Zusammenfassung In diesem Paper stellen wir ein Echtzeit-Szenario zur Überwachung und Steuerung von entfernt laufenden Großsimulationen vor, das auf einer Extraktion von Geometrien aus den Simulationsdaten, deren Übertragung über Hochgeschwindigkeitsnetze zu einem Client und der daraufhin erfolgenden Simulationssteuerung beruht. Wir stellen die Probleme eines solchen Szenarios dar und präsentie...
