This paper presents the details of software development and implementation of a simulation model to be used for performance analysis of the control applied for management of a plug-in electric vehicles charging network. The model is designed to provide an evaluation of the tested control algorithms in terms of efficiency and stability operation. Apart from the control algorithm evaluation the model...
In this paper, a microprocessor-based PMSM drive with three hall-effect sensors for detecting rotor position is studied. First, three PMSM control methods, namely 120° six-step with current limit, 180° six-step with current control, synchronous frame vector control, are compared based on some key performance indexes, such as vibration, acoustic noise and efficiency. According to the analysis, a PMSM...
In cognitive radio applications, the cognitive users should find the spectral hole before it access to the spectrum band licensed to primary users. In order to improve spectral efficiency, wideband spectrum sensing is required for cognitive radio systems. In several environments, some weak primary users (such as microphone signal) are coexisting with strong primary users. In these cases, the weak...
This paper presents quantitative measurements of Primary Hepatocyte (rat liver cell) adhesion on polyelectrolyte multilayer (PEM) films. Measurements are implemented through detaching the cell from the film using a developed highly sensitive micro-force sensing tool. Experimental results demonstrate the measured detaching or adhesion forces of cells on polyelectrolyte multilayer films with different...
