EN Rayleigh waves in a heterogeneous layer over a saturated half space are investigated under plane strain conditions. The dispersion equation is derived using the methods for propagation of free waves in layered media. The effect of heterogeneity on phase velocity is studied by taking different numeri[...]

EN In this paper we propose a clustering technique that extracts sub-clusters based on a simple measure of isotropic symmetry. These sub-clusters are then used as building blocks to form final clusters of any arbitrary shape including concave ones through merging iteratively. The proposed method is tes[...]

EN Different ways of segmentation for cloud images have been developed. The time complexity of these algorithms become vital for implementation. Implementation of Otsu's method of thresholding for segmentation purpose take reasonable computational time for multiple class problem. In this paper, a fract[...]

EN The paper considers the generation and propagation of SH waves in an anisotropic soil layer overlying an elastic half space by a moving stress discontinuity. Stress discontinuity moves with non-uniform velocity and is impulsive in nature. Theories of Biot and Weiskopf are used to formulate the probl[...]

EN The generation of SH-type waves due to sudden application of a stress discontinuity which moves after creation at the sandy layer of finite thickness overlying an isotropic and inhomogeneous elastic halfspace is considered. The displacements are obtained in exact form by the method due to Cagniard m[...]

PL Bezpieczeństwo zastępu w czasie prowadzenia prac ratowniczych w warunkach braku, bądź ograniczonej widoczności, będącej wynikiem silnego zadymienia, jest uzależnione od doświadczenia zastępowego i ratowników. Wchodząc do zadymionej strefy, zastępowy jest zobowiązany do połączenia ratowników w zastęp[...]
EN The safety of mine rescue teams during rescue operations in areas of low or zero visibility due to high smoke concentration depends on the professional experience of the mine rescue officer and the rescuers. Another critical safety component is, among others, connecting the rescue team members with [...]

EN There is potential of using acoustic sounder system to study boundary layer meteorology. The repeatable patterns on sodar-images become necessary and useful to find suitable techniques for computer analysis and interpretation. Image processing and pattern recognition approaches have been explored fo[...]

EN The wool harvesting industry employs workers of varying skill levels that differ in both quality and number of harvested fleeces. As it was unknown how skill affected parameters such as joint posture and loading, the current study comparatively examined 140 wool harvesting workers representing 4 ski[...]

EN This paper presents a mathematical model of a power controller for a high-frequency induction heating system based on a modified half-bridge series resonant inverter. The output real power is precise over the heating coil, and this real power is processed as a feedback signal that contends a closed-[...]
