Exact analytical expressions for the switching delay of an inverter driving an RC load, taking into account the velocity saturation, are obtained. Modified expressions to include theeffectofsource resistance arethen presented.Owing to the limitation on switching current imposed by the velocity saturation mechanism, the switching delay is substantially increased for identical width-io-length rat...

this study was conducted to investigate the effects of applying methods andamount of ammonium polyphosphate (0, 2 and 4 wt%) on fire retardancy andmechanical properties of wood flour/polypropylene composites. the resultsshowed that addition of fire retardant improved the mechanical properties such astensile and flexural strengths and fire retardancy of composites. but by increasingof fire retar...

We develop an original game-theoretical explanation of cyclical herd behaviors, where cyclicity occurs as a strategic equilibrium phenomena triggered by saturation effects associated with mass adoption of the same action. In our model, we show that herd behaviors occur almost surely, and so do cycles if saturation effects are present. Moreover, we show that the length of the transition phase be...

Fault-tolerant constrained attitude controllers are proposed for flexible spacecraft in the presence of input saturation and actuator fault, as well as model uncertainty and external disturbance. Two input saturations, that is amplitude saturation and, amplitude and rate saturation are considered and simple and effective compensators are designed to deal with the effect of input saturation. Two...

Incorrectly setting the camera’s exposure can have a significant negative effect on a photograph. Over-exposing photographs causes pixels to exhibit unpleasant artifacts due to saturation of the sensor. Saturation removal typically involves user intervention to adjust the color values, which is tedious and time-consuming. This paper discusses how saturation can be automatically removed without ...

Concrete is seldom saturated due to its self-desiccation. Even the submerged concrete structures may remain unsaturated for quite a long time. It has been reported the saturation level of pore solution has significant effect on species penetration. However, very little work was proposed regarding the transport properties and serviceability of concrete structures made of blended cementitious mat...

Diptheria toxin (DT) reversibly increases the saturation of the long-chain C18 fatty acids (C18FA) in concentrations which are at least 100-fold smaller than the concentrations which completely inhibit host cell protein synthesis. The concentrations required for induction of the increase in the saturation of the C18FA in fibroblasts are 100-fold smaller than the concentrations for the epithelia...

Colour image segmentation based on the hue component presents some problems due to the physical process of image formation. One of that problems is colour clipping, which appear when at least one of the sensor components is saturated. We have designed a system, that works for a trained set of colours, to recover the chromatic information of those pixels on which colour has been clipped. The chr...
