In this work a machine vision system for inspection (VSI) is presented whose capabilities are able to detect seaming defects in metal cans for fishing food. Conventional method for quality inspection of seaming for cans, and their main dimensional features, are firstly shown. Then, the structure and algorithms for VSI are proposed for this application. This VSI is currently mounted over a conve...

In this paper, a buck half-bridge DC-DC converter is used as a single-stage power factor correction (PFC) converter for feeding a voltage source inverter (VSI) based permanent magnet brushless DC motor (PMBLDCM) drive. The front end of this PFC converter is a diode bridge rectifier (DBR) fed from single-phase AC mains. The PMBLDCM is used to drive a compressor load of an air conditioner through...

ABSTRACT The vertical shear instability (VSI) is a robust phenomenon in irradiated protoplanetary discs (PPDs). While there extensive literature on the VSI hydrodynamic limit, PPDs are expected to be magnetized and their extremely low ionization fractions imply that non-ideal magnetohydrodynamic effects should properly considered. To this end, we present linear analyses of with Ohmic resistivit...

Color centers in silicon carbide (SiC), such as the negative vacancy (VSi?) and neutral divacancy (VSiVC0), have recently been shown to be promising quantum bits (qubits) for a variety of applications communications sensing. Considerable effort has spent on improving performance these optical spin qubits, instability their charge state is an important issue solved. Using electron paramagnetic r...

For high-power electric vehicles (EVs), the drive propulsion based on induction motors is emerging as economical alternative. Compared to conventional motors, open-end winding motor (OEWIM) requires only half dc-bus voltage for given torque. The EV power train dual two-level voltage-source inverter (VSI)-fed OEWIM with isolated dc sources used in this research. uniform state-of-charge (SoC) dis...

Voltage source inverter (VSI) is a good candidate for grid forming microgrid because it provides constant amplitude, frequency, and sinusoidal shape voltage at point of common coupling (PCC). As the separated from utility grid, quality PCC easily affected by type load. To ensure power in operation, three-phase VSI providing automatic compensation unbalanced or nonlinear load presented this pape...

Voltage source inverters (VSIs) are an integral part of electrical vehicles (EVs) to enhance the reliability supply power critical loads in vehicle load (V2L) applications. The inherent properties sliding mode control (SMC) makes it one best available options achieve desired voltage quality under variable conditions. intrinsic characteristic robustness associated with SMC is generally achieved ...

Received May 11, 2013 Revised July 10, 2013 Accepted July 28, 2013 This paper cite comparative performance characteristics of Z-Source inverter fed IM drives with mostly used VSI & CSI fed IM drives. ZSI has both voltages buck and boost capabilities as they allow inverters to be operated in the shoot through state. It employs an exclusive Z-Source network (LC component) to dc-link the main inve...

Resources with quantitative properties, e.g. measurable resources or sources for feature extraction (e.g. fingerprints), play an important role, particularly in scientific areas such as Life Sciences, the medical domain and nature sciences. In this paper we propose similarity-based representation of resources using so called Vectorial Resource Descriptors (VRDs) on the Web. The VRDs are standar...

PURPOSE To investigate the advantages of reducing the partial volume effect (PVE) to enhance the detection of the BOLD signal in fMRI. METHODS A linear phase term was added in k-space to obtain half-voxel shifting of 64 × 64 T2*-weighted echo-planar images. Three sets of image data shifted in the x, y, and diagonal direction, respectively, are combined with the original 64 × 64 data to form t...
