In the operation of aerial ropeways, system load-bearing and running skyline system, which provides ability to move passengers or transported cargo between endpoints route, experiences a high level loading from variety operational loads environmental influences. Those influences form rope tension that is variable along route has decisive influence on main technical economic parameters mobile th...

This work studies the effects of dynamic axial stiffness elastic moorings on behaviour a point absorber wave energy converter. Following two mooring analysis procedures, coupled taut-moored WEC with three legs is performed using FEM program DeepC in irregular conditions. Two synthetic fibre rope materials are investigated, i.e. normally stiff polyester and wire-lay 3-strand nylon rope. The resu...

This paper is concerned with performance optimization of point-to-point communication of scalable video over lossy networks. A variant of the recursive optimal per-pixel estimate (ROPE) is developed and embedded within a ratedistortion (RD) optimized mode selection scheme for SNR scalable video coding. The system allows predicting the current base layer frame from past enhancement layer frame d...

In crane automation systems, precise knowledge of the load position is a key factor for fulfilling positioning accuracy requirements. This contribution presents a nonlinear observer design for harbor cranes which makes use of gyroscope measurements. Both single-pendulum load configurations and more complex double-pendulum configurations are considered. The gyroscope sensors are attached to the ...

In this paper energy bands and Berry curvature of graphene was studied. Desired Hamiltonian regarding the next-nearest neighbors obtained by tight binding model. By using the second quantization approach, the transformation matrix is calculated and the Hamiltonian of system is diagonalized. With this Hamiltonian, the band structure and wave function can be calculated. By using calculated wave f...
