AdvancedTCA*/CGL Advantage: HA and TCO
نویسنده
چکیده
Carrier-grade systems in today’s telecom market have high availability needs; however, current market conditions are forcing telecom equipment providers to look for lower-cost alternatives. In this paper, we discuss Advanced Telecom Computing Architecture (AdvancedTCA), Carrier-Grade Linux (CGL), and how these standards meet the requirements of carrier-grade equipment. We also describe how both of these standards can help increase high availability (HA) and reduce the total cost of ownership (TCO) in carrier-grade systems. We define AdvancedTCA and its relationship to HA and reduced TCO. We also describe AdvancedTCA shelf management and show how AdvancedTCA hardware can enable HA middleware to perform HA functions. When discussing CGL, we focus on CGL requirements related to AdvancedTCA that increase HA and reduce TCO, as well as those that reduce TCO in general.

Heat acclimation: role of norepinephrine in the anterior hypothalamus.
The hypothesis that anterior hypothalamic (AH) sensitivity to norepinephrine (NE) is altered by chronic exercise in the heat was tested in male Sprague-Dawley rats. Treadmill exercise 6 days/wk for 3 wk at 21 m/min was performed at 23 degrees C (control; C) or at 35 degrees C (heat acclimated; HA), progressing from 20 to 50 min/day in 2 wk. Time for core temperature (Tco) to rise from 39.5 to 4...
متن کاملContour coding based rotating adaptive model for human detection and tracking in thermal catadioptric omnidirectional vision.
In this paper, we introduce a novel surveillance system based on thermal catadioptric omnidirectional (TCO) vision. The conventional contour-based methods are difficult to be applied to the TCO sensor for detection or tracking purposes due to the distortion of TCO vision. To solve this problem, we propose a contour coding based rotating adaptive model (RAM) that can extract the contour feature ...
متن کاملThermal analysis of Li2O TeO2 glass
The thermal properties of 0.30Li2O 0.70TeO2 glass are studied. Speci®c heat, Cp, is measured in the 170°C < T < 270°C interval. The Einstein temperature, hA 840 K, is determined from the temperature course of Cp. In the glass transition interval, the heat capacity undergoes an S-shaped transition from the value, Cgl, of the glass to that of undercooled melt, Cp. It is found that Cgl=Cp 0:62. ...

A case of lymphoid blast crisis of Ph’-positive CGL is described in which the blast cells had an immature T cell phenotype. clonal rearrangement and expression of the T cell receptor fi gene, and a rearrangement of the breakpoint cluster region (bcr) on chromosome 22. This case therefore provides definite evidence for transformation C HRONIC granulocytic leukemia (CGL) originates in a multipote...
