Homogenization methods and macro-strength of composites

A multi-phase periodic composite subjected to inhomogeneous shrinkage or temperature deformation and prescribed mechanical loads is considered. The asymptotic homogenisation is applied for calculation of homogenized macrostresses. A non-local approximate macro-strength condition, defined on homogenised stress-field, is derived from the micro-strength conditions and their convergence to the approximate macro-strength condition, as the structure period tends to zero, is proved

A Graph-Partition-Based Scheduling Policy for Heterogeneous Architectures

In order to improve system performance efficiently, a number of systems choose to equip multi-core and many-core processors (such as GPUs). Due to their discrete memory these heterogeneous architectures comprise a distributed system within a computer. A data-flow programming model is attractive in this setting for its ease of expressing concurrency. Programmers only need to define task dependencies without considering how to schedule them on the hardware. However, mapping the resulting task graph onto hardware efficiently remains a challenge. In this paper, we propose a graph-partition scheduling policy for mapping data-flow workloads to heterogeneous hardware. According to our experiments, our graph-partition-based scheduling achieves comparable performance to conventional queue-base approaches.Comment: Presented at DATE Friday Workshop on Heterogeneous Architectures and Design Methods for Embedded Image Systems (HIS 2015) (arXiv:1502.07241

Non-linear optical frequency conversion crystals for space applications

Reliable, long term operation of high-power laser systems in the Earth orbit is not a straightforward task as the space environment entails various risks for optical surfaces and bulk materials. The increased operational risk is, among others, due to the presence of high energy radiation penetrating the metallic shielding of satellites and inducing absorption centers in the bulk of optical components, and vacuum exposure which can deteriorate coating performance. Comprehensive testing for analyzing high-energy radiation effects and mitigation procedures were performed on a set of frequency conversion crystals and are discussed in this paper. In addition to a general resistance to space environmental effects, the frequency conversion crystals were subjected to a comparative analysis on optimum third harmonic efficiency, starting from pulsed 1064 nm laser radiation, with the goal of exceeding a value of 30 %. Concomitant modeling supported the selection of crystal parameters and the definition of crystal dimensions

Конкуренция, кредит и капитализация как ключевые маховики кризиса любой экономики

Вопросы, рассмотренные в данной статье, в настоящее время приобрели чрезвычайную актуальность в силу того, что реальные результаты развития экономик (хозяйств) как на макроуровне, так и на микроуровнях опровергают существенный ряд декларируемых экономических аксиом. Цель настоящей работы: выявить очевидные противоречия и пороки, содержащиеся в постулируемых аксиомах развития экономик, таких как конкуренция, кредит и капитализация, которые и являются ключевыми драйверами развития кризисных процессов. Методы исследования: сравнительный анализ и синтез теоретических фундаментальных экономических источников и посылок, практических исследований и личного опыта различных российских и зарубежных ученых и бизнесменов-практиков, результатов, наблюдений и выводов, вытекающих из персонального практического опыта автора и его собственных теоретических исследований и измышлений. Результаты: в работе достаточно убедительно продемонстрирован кризисный целевой характер таких экономических механизмов, как конкуренция, кредит и капитализация, которые изначально аксио-матично декларируются как ключевые драйверы развития экономик
