IEEE 802.16 (WiMAX) and IEEE 802.11 (WiFi) are different wireless access technologies with the former being used in Metropolitan Area Networks and the latter used in Local Area Networks. With the increase in popularity of WiMAX and WiFi networks, it is expected that mobile devices in future will be equipped with these radios for data access. Such a scenario presents us with an opportunity to utilize...
Charge carrier transport properties and molecular doping in graphene grown epitaxially on both Si and C-faces of 6H-SiC have been investigated. Our results indicate that in C-face multiplayer graphene (MLG) p-type charge carriers are dominant and in Si-face few layer graphene (FLG), charge carriers are mostly n-type. A strong correlation between conductance change and SWF change due to molecular doping...
We consider the problem of processing exact results for sliding window joins over data streams with limited memory. Existing approaches deal with memory limitations by shedding loads, and therefore cannot provide exact or even highly accurate results for sliding window joins over data streams showing time varying rate of data arrivals. We provide an exact window join (EWJ) algorithm incorporating...
To meet advancing market demands, microprocessor embedded memory applications require denser and faster memory arrays with each process generation. Recent work presented an 18.5 ns 128 Mb DRAM with a floating body cell for conventional DRAM products and a 4 Mb memory macro using a memory cell built with two floating body transistors. This paper presents a floating-body Z-RAMreg memory cell to fabricate...
In this paper, transmission line parameters such as characteristic impedance Z0, effective dielectric constant epsiveff, attenuation constant alpha of Suspended Microstrip line on multilayer low resistivity silicon substrate are investigated. Effect of variation in the thickness of Si3N4, polyimide and metal layer are studied using HFSS. Due to suspended nature, significant reduction in transmission...
