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...

A serious constraint in multilevel inverters is the capacitor voltage-balancing problem. The unbalance of the different DC voltage sources of the five-level Neutral Point Clamping Voltage Source Inverter (NPC-VSI) constituted the major limitation for the use of this power converter. To remedy to this problem, a new control solution to compensate the unbalanced DC voltages for the five-level NPC...

BACKGROUND AND PURPOSE Visuospatial inattention (VSI) and language impairment (LI) are often present early after stroke and associations with an unfavorable short-term functional outcome have been reported. The purpose of this study was to investigate whether a screening of VSI and LI as indicators of cortical symptoms early after stroke could predict long-term functional outcomes. METHODS A ...

AIM Pulmonary arteries are mainly innervated by sympathetic vasoconstrictor and parasympathetic vasodilatory fibers. We examined whether there is a relationship between the neuron densities of hilar parasympathetic ganglia and pulmonary vasospasm in subarachnoid hemorrhage (SAH). MATERIAL AND METHODS Twenty-four rabbits were divided into two groups: control (n=8) and SAH (n=16). The animals w...

Here we report that a serotonergic neuron evokes two distinct neuromodulatory actions with different state, timing, and firing pattern dependencies. These neuromodulatory actions may have important behavioral functions. In the mollusc, Tritonia diomedea, EPSCs evoked by ventral swim interneuron B (VSI) exhibited intrinsic plasticity; after a spike train, EPSC amplitude increased from a basal st...
