in this paper, a non-isothermal two-phase flow in the cathode gas diffusion layer (gdl) of pem fuel cell is modeled. the governing equations including energy, mass and momentum conservation equations are solved by numerical methods. also, the optimal values of the effective parameters such as the electrodes porosity, gas diffusion layer (gdl) thickness and inlet relative humidity are calculated...

a total of 148 groundwater samples were collected from bore wells from thirumanimuttar sub-basin for two seasons to identify major geochemical process activated to alter groundwater chemistry. the study revealed relationships with the lithology and anthropogenic process. groundwater in the region was dominated by na – ca – mg and cl and hco3 types. the (ca +mg) versus tz+ plot for both seas...

Related Concepts – Overexposure – Radiometric response functions – Full well capacity – Blooming – Dynamic range – High dynamic range imaging Definition In imaging, saturation is a type of distortion where the recorded image is limited to some maximum value, interfering with the measurement of bright regions of the scene.

Assuming that ORD is ! + !-Erdd os we show that if a class forcing amenable to L (an L-forcing) has a generic then it has one deenable in a set-generic extension of LO # ]. In fact we may choose such a generic to be periodic in the sense that it preserve the indiscernibility of a nal segment of a periodic subclass of the Silver indiscernibles, and therefore to be almost codable in the sense tha...

The method of Deibler, Holmes, Campbell, and Gans (1959) is a quick, accurate, and reliable method for the determination of oxygen saturation. The results should be calibrated against those obtained by the Van Slyke method, and the setting, sensitivity, and reliability of the spectrophotometer should be carefully established. This is especially necessary to meet the stringent requirements for a...

Let $G=(V,E)$ be a simple connected graph. A matching $M$ in a graph $G$ is a collection of edges of $G$ such that no two edges from $M$ share a vertex. A matching $M$ is maximal if it cannot be extended to a larger matching in $G$. The cardinality of any smallest maximal matching in $G$ is the saturation number of $G$ and is denoted by $s(G)$. In this paper we study the saturation numbe...
