Five different models have been proposed in recent years to interpret the quasi-saturation of interface trap generation in PMOS Transistors due to Negative Bias Temperature Instability (NBTI). We use both analytical and numerical methods to capture the essence of these models and show that these models predict very different temperature, thickness, and voltage dependence regarding the onset of ...

A novel voltage reference has been proposed and simulated using a 0.18μm CMOS process in this paper. A near-zero temperature coefficient voltage is achieved in virtue of the bias voltage subcirciut which consists of two MOSFETs operating in the saturation region. The kind of bias voltage subcirciut is used to adjust the output voltage and compensate the curvature. The output voltage is equal to...

Insect water balance plays an important role in determining energy budgets, activity patterns, survival, and population dynamics and, hence, geographic distribution. Tsetse (Glossina spp.) are important vectors of human and animal disease occupying a wide range of habitats in Africa and are notable for their desiccation resistance in xeric environments. Here, we measure water balance and relate...

A set of relative permeability relations for simultaneous ow of steam and water in porous media have been derived from experiments conducted under conditions that eliminate most errors associated with saturation and pressure measurements. These relations show that the relative permeability for steam phase in porous media varies linearly with saturation. The liquid phase, however shows a variati...

The effects of environmental factors on variations of dissolved oxygen (DO) saturation was assessed in 2 estuaries (Bilbao and Urdaibai) in the Bay of Biscay with contrasting hydrography and anthropogenic impact, for the period 1997 to 2006, using generalised additive models (GAMs) and generalised additive mixed models (GAMMs). Spatial and temporal variations in DO saturation and the current se...

In this paper, the rough set theory is used to deal with the relations between patient's temperature, oxygen saturation, blood pressure and decision ADM-DECS in care of postoperative patients, we select 28 postoperative patients as a sample, take ADM-DECS as a decision attribute and take patient's temperature, oxygen saturation, blood pressure as

In this work a mathematical model is developed for measuring orientation of red blood cells in magnetic field and governing the bio-magnetic fluid flow is presented for the viscous, two-dimensional, incompressible and laminar time dependent heat transfer flow is considered. Expressions describing the variation of the saturation magnetization of the fluid with temperature or the magnetic field i...
