Active Filter Control Method Based on Direct Power Control for Compensating Reactive Powers due to Unbalanced Voltages and Nonlinear Loads

Active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. This paper proposes a control scheme based on the instantaneous active and reactive power. The inverter of this active filter is a three-phase, two-level converter. Space vector technique is used as modulators and pattern genera...

Telecobalt Machine Beam Intensity Modulation with Aluminium Compensating Filter Using Missing Tissue Approach

Introduction: The present study aimed to generate intensity-modulated beams with Aluminium compensating filters for a conventional telecobalt machine based on the outputs of a treatment planning system (TPS) performing forward planning and cannot simulate directly the compensating filter. Materials and Methods: In order to achieve the beam intensity modulation during treatment planning with th...

Attacking (EC)DSA Given Only an Implicit Hint

We describe a lattice attack on DSA-like signature schemes under the assumption that implicit information on the ephemeral keys is known. Inspired by the implicit oracle of May and Ritzenhofen presented in the context of RSA (PKC2009), we assume that the ephemeral keys share a certain amount of bits without knowing the value of the shared bits. This work also extends results of Leadbitter, Page...

Joint pricing and production management: a geometric programming approach with consideration of cubic production cost function

Coordination and harmony between different departments of a company can be an important factor in achieving competitive advantage if the company corrects alignment between strategies of different departments. This paper presents an integrated decision model based on recent advances of geometric programming technique. The demand of a product considers as a power function of factors such as produ...

A geometric approach to consideration of control variable limits for wheeled mobile robots with kinematic constraints

Abstract: Subject of this paper is a method for consideration of control variable limits of single actuators in a redundant driven kinematic structure of a wheeled mobile robot (wmr). It is assumed that the desired robot state is given by the translational and rotational velocity of a coordinate system fixed to the robot frame. With the assumption of rigid body elements, motion is possible only...
