(2004-09-24)Uranium adsorption to Hanford sediment was studied for various pH, total inorganic carbon concentrations, and total U(VI) concentrations. Both batch and transport studies were done in an attempt to understand the adsorpt ...
-
(1978-10-12)The objectives of this study are (1) to compare the costs of providing camping among different types of U.S. Forest Service developed campgrounds in Oregon and Washington and (2) to help determine possible policy impl ...
-
(1970-04-16)This study attempts to show that competitive advantage alone does not determine the directions of trade in kraft liner. Trade depends on comparative advantage and especially on familiarity with foreign demand. Implicatio ...
-
(2009-02-26)We consider the problem of tactical assault planning in real-time strategy games where a team of friendly agents must launch an assault on an enemy. This problem offers many challenges including a highly dynamic and unce ...
-
(2005-04-29)This thesis takes an in-depth look at specific behaviors that are putting Maasai women at risk for HIV/AIDS in Kenya. Methods used include in-depth interviews, focus group discussion, demographic data collection, and n ...
-
(2009-06-17)In Radio Frequency Integrated Circuits (RFIC) or high frequency digital ICs, there is a demand to probe the internal nodes for testing. The ultra low capacitance RFIC probe presented in his work is a flexible tool for ...
-
(2009-04-01)An ultra low power crystal oscillator that provides a frequency reference for battery powered timekeeping applications is presented. An amplitude control circuit is employed to ensure that minimum current is consumed. A ...
-
(1998-11-23)The major limiting factor of DRAM access time is the low transconductance of the MOSFET's which have only limited current drive capability. The bipolar junction transistor(BJT) has a collector current amplification fac ...
-
(2009-01-05)A fully integrated CMOS GPS receiver RF front end optimized for low power operation is presented. The system operates with a supply voltage down to 250 mV. A prototype has been fabricated in a 0.13μm CMOS process and in ...
-
(2011-07-01)This thesis presents a low-energy application specific digital controller for a battery-free 2.4 GHz wireless sensor network (WSN) node. The digital controller has been designed and fabricated in a standard 0.13 μm CMOS ...
-
(2009-04-23)Low energy design techniques for digital circuits are examined to determine their suitability for use in a digital logic controller for wireless sensor network nodes. Transistor level simulations are used to evaluate the ...
-
(2010-05-05)In wireless sensor network applications, low-power operation of the wireless receiver is critical. To address this need an ultra-low power Binary Frequency Shift Keying (BFSK) receiver using the super-regenerative archit ...
-
(2011-06-29)As the number of autonomous data collection applications keep increasing, the demand for wireless sensor networks (WSNs) has seen explosive growth. In this dissertation, an ultra-low-energy WSN transmitter is developed t ...
-
(2012-06-13)Indoor localization systems have a variety of applications such as tracking of assets, indoor robot navigation, and monitoring of people (e.g. patients) in hospitals or at home. Global positioning system (GPS) offers l ...
-
(2004-11-23)This paper proposes a novel means of using analog correlators to improve upon existing Ultra-Wideband receiver architectures. Current architectures aim for an all-digital design for the sake of ease of implementation a ...
-
(1987-09-08)The possible effect of oxidation [processing with or without sulfur dioxide (±S0₂)] and of pre-ultrafiltration treatment of juices with enzymes and fining agents on flux, and on juice color, composition and stability w ...
-
(1982-12-03)Ultrafiltration (UF), using Romicon pilot-scale hollow-fiber cartridges (Model HFXS-MK11) in the batch mode, was investigated as a possible procedure for clarifying, stabilizing and preserving White Riesling (WR) and ...
-
(1983-08-29)The feasibility of using hollow fiber ultrafi1tration for clarification, stabilization and preservation of white grape juice was evaluated. Flux and process parameters of a hollow fiber membrane ultrafi1tration unit ( ...
-
(1981-08-10)Ultrafiltration of d'Anjou pear juice in the batch mode with a Romicon HFXS MXII pilot-scale ultrafilter produced a "sparkling clear", light-colored permeate which was sterile, essentially free of pectin, and lower in ...
-
(1995-03-15)Five Ultra light Fabric Reflux Tubes (UFRTs) were tested in a thermal vacuum chamber at the National Aeronautics and Space Administration's Johnson Space Center in September 1994. These test articles were design and fabr ...
