Broadband acoustic source processing in a noisy shallow ocean environment
Acoustic sources found in the ocean environment are spatially complex and broadband, complicating the analysis of received acoustic data considerably. A model-based approach is developed for a broadband source in a shallow ocean environment characterized by a normal-mode propagation model. Here we develop the optimal Bayesian solution to the broadband pressure-field enhancement and modal function extraction problem.

BSE (“Mad Cow Disease”): A Brief Overview
The appearance of BSE (bovine spongiform encephalopathy or “mad cow disease”) in North America in 2003 raised meat safety concerns and disrupted trade for cattle and beef producers. A major issue for Congress has been how to rebuild foreign confidence in the safety of U.S. beef and regain lost markets like Japan and Korea. Among other issues are whether additional measures are needed to further protect the public and cattle herd, and concerns over the relative costs and benefits of such measures for consumers, taxpayers and industry.

Building a Road from Light to Energy
Representing the Center for Solar and Thermal Energy Conversion (CSTEC), this document is one of the entries in the Ten Hundred and One Word Challenge. As part of the challenge, the 46 Energy Frontier Research Centers were invited to represent their science in images, cartoons, photos, words and original paintings, but any descriptions or words could only use the 1000 most commonly used words in the English language, with the addition of one word important to each of the EFRCs and the mission of DOE energy. The mission of the Center for Solar and Thermal Energy Conversion (CSTEC) is to design and to synthesize new materials for high efficiency photovoltaic (PV) and thermoelectric (TE) devices, predicated on new fundamental insights into equilibrium and non-equilibrium processes, including quantum phenomena, that occur in materials over various spatial and temporal scales.

Calculation of tune vs amplitudes for the new low beta quadrupoles
I calculate the tune as function of amplitude due to higher multipole errors (in particular the dodecapole) in the new low beta quadrupoles. The results indicate that these multipoles are not expected to give rise to serious problems for the next Tevatron Collide run with two interaction regions.

Calibration Procedures for a Two-Modulator Generalized Ellipsometer
A Two-Modulator Generalized Ellipsometer (2-MGE) has been extremely useful in characterizing optical properties of uniaxial bulk materials, thin films and diffraction gratings. The instrument consists of two polarizer-photoelastic modulator pairs, one operating as the polarization state generator and the other as the polarization state detector. Each photoelastic modulator operates at a different remnant frequency (such as 50 kHz and 60 kHz), making it possible to measure eight elements of the reduced sample Mueller matrix simultaneously. In certain configurations, light reflection from non-depolarizing anisotropic samples can be completely characterized by a single measurement, and the entire reduced Jones matrix can be determined, including the cross polarization coefficients. The calibration of the instrument involves the measurement of the azimuthal angle of the polarizer with respect to the modulator, the modulation amplitude, and the modulator strain for each polarizer photoelastic modulator pair, where the last two are functions of wavelengths. In addition, it is essential to calibrate the azimuthal angles of the polarization state generator and the polarization state detector with respect to the plane of incidence in the ellipsometry configuration that is used in the measurements. Because two modulators operating at different frequencies are used, these calibrations are actually easier and more …

Cannon Individual Letters - 117
I am very concerned about the BRAC Commission's decision to close Cannon Air Force Base. * I do not believe the Commission is fully aware of the unique attributes that Cannon offers to our national defense. These include an abundance of air space and no encroachment issues, a bombing range that is only seconds away, the airspace to fly at supersonic speeds, and ideal year-round flying weather, among many others. In addition to the military value to the nation, Cannon has been supported over the last 50 hears by the local communities like no other in the country. We consider Cannon a part of our family. The closure of Cannon will also have a devastating impact on our economy. It has been estimated that the area will lose at least 20 percent of its workforce, plus the ripple effect that we will have on our public and higher education systems. Please reconsider all the facts before making your final decision.

Cannon Individual Letters - 172
I am very concerned about the Department of Defense's recommendation that Cannon Air Force Base should be closed. Cannon Air Force Base should not be on the BRAC closure list for many reasons. Listed below are just a few reasons on why Cannon Air Force should not be on the list: Cannon does not fit the criteria provided for base closure. The weather in Eastern New Mexico provides year round training ability. Cannon has the space and facilities to accommodate joint war-fighting, training, and readiness as was evidenced by the recent joint training effort between Cannon and the US Navy.

Carbide Cathode Studies, Physical and Chemical Redeposition. Quarterly Progress Report, April 1, 1962-June 30, 1962
The utilization of physical and chemical processes to reduce the rate of vapor loss of thermionic emitters composed of mixed carbides of U and Zr in order to increase the permissible operating temperature is being studied. Preliminary, qualitative results obtained from study of physical redeposition processes showed that increasing the collector temperature may markedly reduce the rate of weight loss from a UC emitter operating at 2053 deg K. The requisite experimental equipment for studies of chemical transport processes was designed and constructed. Experiments will proceed through both a physical chemistry approach to an understanding of the transport processes and a technique to evaluate the efficacy of possible combinations of chemical species by monitoring the electron emission from diodes containing such mixtures.

CDF top quark production and mass

A 4.8{sigma} excess of candidate events establishes the existence of the top quark. The t{bar t} production cross section is measured to be {sigma}{sub t{bar t}} = 7.6{sub {minus}2.0}{sup +2.4} pb with branching Br(t {yields} Wb) = 0.87{sub {minus}0.30}{sup +0.13}(stat) {sub {minus}0.11}{sup +0.13}(syst).

Central Intelligence Agency: Observations on GAO Access to Information on CIA Programs and Activities
Testimony issued by the General Accounting Office with an abstract that begins "Oversight of the Central Intelligence Agency (CIA) generally comes from two select committees of Congress and the CIA's Inspector General. GAO has broad authority to evaluate CIA programs. In reality, however, GAO faces both legal and practical limitations on its ability to review these programs. For example, it has no access to some CIA "unvouchered" accounts and cannot compel its access to foreign intelligence and counterintelligence information. In addition, as a practical matter, GAO is limited by the CIA's level of cooperation, which has varied through the years. GAO has not actively audited the CIA since the early 1960s, when it discontinued such work because CIA was not providing it with enough access to information to allow GAO to do its job. The issue has arisen since then from time to time as GAO's work has required some level of access to CIA programs and information. However, given a lack of requests from Congress for GAO to do specific work at the CIA and its limited resources, GAO made a decision not to pursue the issue further. Today, GAO's dealings with the CIA are mostly limited to information …

Characterizing the Effects of High Wind Penetration on a Small Isolated Grid in Arctic Alaska
This paper examines the operating characteristics of the wind-diesel system in Kotzebue, Alaska, operated by Kotzebue Electric Association (KEA). KEA began incorporating wind power into its 100% diesel generating system in 1997 with three 66 kW wind turbines. In 1999, KEA added another seven 66 kW turbines, resulting in the current wind capacity of 660 kW. KEA is in the process of expanding its wind project again and ultimately expects to operate 2-3 MW of wind capacity. With a peak load of approximately 4 MW and a minimum load of approximately 1.6 MW, the wind penetration is significant. KEA is currently experiencing greater than 35% wind penetration, sometimes for several consecutive hours. This paper discusses the observed wind penetration at KEA and evaluates the effects of wind penetration on power quality on the KEA grid.
