Upper Bounds On The Number Of Channels To Ensure Collision-Free Communications In Multi-Channel Wireless Networks Using Directional Antennas, 2009 Macau University of Science and Technology
Upper Bounds On The Number Of Channels To Ensure Collision-Free Communications In Multi-Channel Wireless Networks Using Directional Antennas, Hong-Ning Dai, Kam-Wing Ng, Min-You Wu
Recent studies have found that using multiple channels can separate concurrent transmissions and significantly improve network throughput. However, these studies have only considered wireless nodes that are equipped with omni-directional antennas, which have high interference. On the other hand, other researchers have found that using directional antennas in wireless networks can reduce interference and improve the network performance. But their studies have only considered single channel to be used in wireless networks with directional antennas. Thus, integrating the two technologies of multiple channels and directional antennas together can potentially bring more benefits. Some previous works have studies the capacity on ...
Carbon Accounting Initiatives: Case Study Of A Petroleum Refinery In Malaysia To Prepare For Future Carbon Market, Abdul Aziz Abdul Raman
Abdul Aziz Abdul Raman
Petroleum refining process produces a large amount of atmospheric pollutants including greenhouse gases which are attributed to global warming. The international community inevitably addressed the global warming issue by introducing a market-based mechanism known as Emission Trading Systems (ETS) under the Kyoto Protocol which imposes binding limits to developed nations using three flexibility mechanisms, including the Clean Development Mechanism (CDM). © School of Engineering, Taylor's University College.

Controlled Language - Does My Company Need It?, 2009 Selected Works
Controlled Language - Does My Company Need It?, Uwe Muegge
A controlled language is a natural language, as opposed to an artificial or constructed language. Natural languages such as English or German are languages that are used by humans for general communication. A controlled language differs from the general language in two significant ways: 1. The grammar rules of a controlled language are typically more restrictive than those of the general language. 2. The vocabulary of a controlled language typically contains only a fraction of the words that are permissible in the general language.
Stabilization Of Thin Liquid Films Flowing Over Locally Heated Surfaces Via Substrate Topography, 2009 University of Massachusetts - Amherst
Stabilization Of Thin Liquid Films Flowing Over Locally Heated Surfaces Via Substrate Topography, N Tiwari, Jm Davis
Jeffrey M. Davis
A long-wave lubrication analysis is used to study the influence of topographical features on the linear stability of noninertial coating flows over a locally heated surface. Thin liquid films flowing over surfaces with localized heating develop a pronounced ridge at the upstream edge of the heater. This ridge becomes unstable to transverse perturbations above a critical Marangoni number and evolves into an array of rivulets even in the limit of noninertial flow. Similar fluid ridges form near topographical variations on isothermal surfaces, but these ridges are stable to perturbations. The influence of basic topographical features on the stability of the ...

Ss-Dna Functionalized Ultra-Thin-Film Aln Contour-Mode Resonators With Self-Sustained Oscillator For Volatile Organic Chemical Detection, Matteo Rinaldi, Brandon Duick, Chiara Zuniga, Chengjie Zuo, Gianluca Piazza
This paper reports on the design and experimental verification of a new class of nanoscale gravimetric sensors based on ultra-thin-film AlN Contour-Mode Resonant Sensor (CMR-S) functionalized with ss-DNA and connected to a chip-based self-sustaining oscillator loop (fabricated in the ON Semiconductor 0.5 μm CMOS process) for direct frequency read-out. The 220 MHz oscillator based on the ultra-thin AlN CMR-S exhibits an Allan Variance of ∼20 Hz for 100 ms gate time. The sensor affinity for the adsorption of volatile organic chemicals such as 2,6 dinitroluene (DNT, a simulant for explosive vapors) is enhanced by functionalizing the top gold ...
Poly(Beta-Alanoid-Block-Beta-Alanine)S: Synthesis Via Cobalt-Catalyzed Carbonylative Polymerization And Self-Assembly, 2009 University of Akron Main Campus
Poly(Beta-Alanoid-Block-Beta-Alanine)S: Synthesis Via Cobalt-Catalyzed Carbonylative Polymerization And Self-Assembly, Shaohui Lin, Xinfei Yu, Yinfeng Tu, Hongyu Xu, Stephen Z. D. Cheng, Li Jia
The titled diblock copolymers are synthesized via cobalt-catalyzed living carbonylative polymerization of N-alkylaziridines under moderate pressures followed by a deprotection step. The poly(beta-alanine) block is solubilized by the poly(beta-alanoid) block in chloroform and remains fully hydrogen-bonded in the form of a sheet-like assembly.
Production Of Jet And Diesel Fuel Range Alkanes From Waste Hemicellulose-Derived Aqueous Solutions, 2009 University of Massachusetts - Amherst
Production Of Jet And Diesel Fuel Range Alkanes From Waste Hemicellulose-Derived Aqueous Solutions, George W. Huber, R. Xing, A. V. Subrahmanyam, H. Olcay, W. Qi, G. P. Van Walsum, H. P. Pendse
George W. Huber
In this paper we report a novel four-step process for the production of jet and diesel fuel range alkanes from hemicellulose extracts derived from northeastern hardwood trees. The extract is representative of a byproduct that could be produced by wood-processing industries such as biomass boilers or pulp mills in the northeastern U.S. The hemicellulose extract tested in this study contained mainly xylose oligomers (21.2 g/l xylose after the acid hydrolysis) as well as 0.31 g/l glucose, 0.91 g/l arabinose, 0.2 g/l lactic acid, 2.39 g/l acetic acid, 0.31 ...
