The maximum loadability point of a power system is usually termed as saddle node bifurcation point (SNBP). This is also known as voltage collapse point on a PV-curve. The distance to voltage collapse point from the current operating point also known as voltage stability margin (VSM) depends on the direction of load increase at load buses. In view of this the paper describes a methodology for determining...
The following paper describes the valid optimization problem of multi-element circular array that contains 16 equal-length dipole antennas surrounding given two-spherical object. The task of the authors was to maximize the specific absorption rate (SAR) inside the inner object, while maintaining its minimum value in the external sphere. The proposed approach includes changes in the powers and phases...
The paper considers the optimization issue of eight dipole antennas array surrounding the tested object. The goal was to maximize the specific absorption rate (SAR) in the target volume, while minimizing the same parameter in the outer object. The SAR optimization was prepared by means of the powers (amplitudes) and the phases used to excite the individual antenna elements of the array. Presented...
Surplus by-product gas (SBPG) in a steel plant is the difference between gas production and consumption. Dynamic programming (DP) has been observed to be a useful method for SBPG dynamic allocation. However, in the SBPG allocation problem, standard dynamic programming (SDP) usually suffers from dimensionality. In this study, a novel dynamic programming method with a reduced state space algorithm (RSS-DP)...
Cryosurgery is a medical technique to destroy unwanted tissue using extreme low temperature from a medium conducted using one or some cryoprobes with an minimum risk. Conventionally the configuration of cryoprobes (the number of cryoprobes and how to place them) has been applied using experience from trial and error methods of the cryosurgeon, so that it requires a method to optimize the configuration-to...
