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 the mollusk, Tritonia diomedea, the serotonergic dorsal swim interneuron (DSI) produces spike timing-dependent neuromodulation (STDN) of the synaptic output of ventral swim interneuron B (VSI) resulting in a biphasic, bidirectional change of synaptic strength characterized by a rapid heterosynaptic potentiation followed by a more prolonged heterosynaptic depression. This study examined the m...

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...

Traditionally, the statistical quality control techniques utilize either an attributes or variables product quality measure. Recently, some methods such as three-level control chart have been developed for monitoring multi attribute processes. Control chart usually has three design parameters: the sample size (n), the sampling interval (h) and the control limit coefficient (k).The design parame...

We show that the higher-dimensional vanishing scalar invariant (VSI) spacetimes with fluxes and dilaton are solutions of type IIB supergravity, and we argue that they are exact solutions in string theory. We also discuss the supersymmetry properties of VSI spacetimes. [PACS: 04.20.Jb, 04.65.+e]

This paper develops discontinuous space vector PWM (DPWM) techniques for a five-phase two-level voltage source inverter (VSI). Space vector model of a five-phase VSI shows that there exist 32 space vectors with three different lengths forming three concentric decagons. Application of outer most and middle set of space vectors to implement Space vector PWM yield nearly sinusoidal output. Thus th...

Due to the rapid advancement of power semiconductor devices, use voltage source inverters (VSIs) has gained widespread acceptance. As a consequence, performance inverter emerged as critical aspect that is highly reliant on modulation strategy. The pulse width (PWM) technique most widely utilized method controlling switches VSI. Power quality always considered an industrial concern for VSI-based...
