This paper first discusses the machine to machine (M2M) domain architecture which becomes the basic model for hybrid Medium Access Control (MAC) protocols for large M2M networks and also it sets the background for hybrid MAC scheme. A review of the contention based and reservation based MAC protocols used in M2M networks is then made. Refer ences Liu,Y. , Yuen, C. , Chen, J. and Cao, X. 2013. A...

this study examined the influence of pre-frying treatments and oil type on the moisture outflow and oil uptake during the frying of potato strips. the pre-treatments were 6 min blanching in a 85°c a water bath containing 0.5% calcium chloride and immersion in a 1% solution of carboxymethyl cellulose; 6 min blanching in a 85°c water bath containing 0.5% calcium chloride and immersion in a 2% sol...

The system CaO-MgO-SiO2-CO2-H20 is an important model for many igneous and metamorphic processes, including the generation and differentiation of carbonatite and associated silicate magmas. We have experimentally established the vapor-saturated solidus for the system CaO-MgO-CO2-H20 from 595øC/1 kbar to <500øC/40 kbar, about 25øC lower than the corresponding temperatures for the CaOCO•-H•O syst...

Preconditioning the heart by brief coronary (CAO) or mesenteric artery occlusion (MAO) can protect against damage during subsequent prolonged CAO and reperfusion. The role of bradykinin (BK) in remote cardiac preconditioning by MAO is investigated by antagonizing the BK B(2) receptor [Hoechst 140 (HOE-140)] or simulating local BK release by mesenteric intra-arterial infusion. Anesthetized male ...

In Chinese calligraphy cao shu is regarded as a kind of free form art which differs from other styles greatly in its less constrained strokes and brush textures. In this paper we present a framework for synthesizing cao shu realistically. In our system, we adopt different brush texture patches (BTPs) collected from hand-written artworks to represent the solid and hollow strokes appearing in cao...

Despite decades of studies of calcium-silicate-hydrate (C-S-H), the structurally complex binder phase of concrete, the interplay between chemical composition and density remains essentially unexplored. Together these characteristics of C-S-H define and modulate the physical and mechanical properties of this "liquid stone" gel phase. With the recent determination of the calcium/silicon (C/S = 1....

Formation of partly dissociated water chains is observed on CaO(001) films upon water exposure at 300 K. While morphology and orientation of the 1D assemblies are revealed from scanning tunneling microscopy, their atomic structure is identified with infrared absorption spectroscopy combined with density functional theory calculations. The latter exploit an ab initio genetic algorithm linked to ...
