Exploration of technologies of use to civil security forces

Exploration of technologies of use to civil security forces

Date: December 1, 1998
Creator: Farnum, E.H.; Petrovic, J.; McClellan, K.; Trujillo, E.; Neuman, A.; Lounsbury, B. et al.
Description: This is the final report of a two-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The objective was to determine whether armor tile technology could be used to solve problems of civil law enforcement as identified by the New Mexico State Police. Most of the effort focused on the design and construction of a lightweight, portable box that could contain the shrapnel and redirect the blast from a steel-pipe/black-powder bomb. The bomb box task was carried out in collaboration with two companies, Foster Miller, Inc. and Ordnance Body Armor Co., who constructed most of the boxes tested. The results of the tests indicated that soft, flexible fabrics are superior to hard tiles in containing the bomb fragments. Subsequent to these experiments, Foster Miller has developed a bomb container that is commercialized and is currently being sold to law enforcement agencies.

Exploration of the El Hoyo-Monte Galan Geothermal Concession. Final report

Exploration of the El Hoyo-Monte Galan Geothermal Concession. Final report

Date: December 1997
Creator: unknown
Description: In January 1996 Trans-Pacific Geothermal Corporation (TGC) was granted a geothermal concession of 114 square kilometers from the Instituto Nicaragueense de Energie (INE) for the purpose of developing between 50 and 150 MWe of geothermal electrical generating capacity. The Concession Agreement required TGC to perform geological, geophysical, and geochemical studies as part of the development program. TGC commenced the geotechnical studies in January 1996 with a comprehensive review of all existing data and surveys. Based on this review, TGC formulated an exploration plan and executed that plan commencing in April, 1996. The ground magnetic (GM), self potential (SP), magnetotelluric/controlled source audio magnetotelluric (MT/CSAMT) and one-meter temperature surveys, data integration, and synthesis of a hydrogeologic model were performed. The purpose of this report is to present a compilation of all data gathered from the geophysical exploration program and to provide an integrated interpretation of that data.

Exploration of the Equilibrium Operating Space For NSTX-Upgrade

Exploration of the Equilibrium Operating Space For NSTX-Upgrade

Date: April 25, 2012
Creator: Gerhardt, S. P.; Andre, R. & Menard, J. E.
Description: This paper explores a range of high-performance equilibrium scenarios available in the NSTX-Upgrade device [J.E. Menard, submitted for publication to Nuclear Fusion]. NSTX-Upgrade is a substantial upgrade to the existing NSTX device [M. Ono, et al., Nuclear Fusion 40, 557 (2000)], with significantly higher toroidal field and solenoid capabilities, and three additional neutral beam sources with significantly larger current drive efficiency. Equilibria are computed with freeboundary TRANSP, allowing a self consistent calculation of the non-inductive current drive sources, the plasma equilibrium, and poloidal field coil current, using the realistic device geometry. The thermal profiles are taken from a variety of existing NSTX discharges, and different assumptions for the thermal confinement scalings are utilized. The no-wall and idealwall n=1 stability limits are computed with the DCON code. The central and minimum safety factors are quite sensitive to many parameters: they generally increases with large outer plasmawall gaps and higher density, but can have either trend with the confinement enhancement factor. In scenarios with strong central beam current drive, the inclusion of non-classical fast ion diffusion raises qmin, decreases the pressure peaking, and generally improves the global stability, at the expense of a reduction in the non-inductive current drive fraction; cases with ...

Explorations in combining cognitive models of individuals and system dynamics models of groups.

Explorations in combining cognitive models of individuals and system dynamics models of groups.

Date: July 1, 2008
Creator: Backus, George A.
Description: This report documents a demonstration model of interacting insurgent leadership, military leadership, government leadership, and societal dynamics under a variety of interventions. The primary focus of the work is the portrayal of a token societal model that responds to leadership activities. The model also includes a linkage between leadership and society that implicitly represents the leadership subordinates as they directly interact with the population. The societal model is meant to demonstrate the efficacy and viability of using System Dynamics (SD) methods to simulate populations and that these can then connect to cognitive models depicting individuals. SD models typically focus on average behavior and thus have limited applicability to describe small groups or individuals. On the other hand, cognitive models readily describe individual behavior but can become cumbersome when used to describe populations. Realistic security situations are invariably a mix of individual and population dynamics. Therefore, the ability to tie SD models to cognitive models provides a critical capability that would be otherwise be unavailable.

Description: The objectives of this project are to: (1) study the scope of hydrothermal pretreatment of coal on subsequent conversion, (2) identify and study the chemical or physical causes of this effect, and (3) attempt to elucidate the chemistry responsible for any coal-resid synergisms. This project is divided into three tasks. This quarter the authors concentrated on Tasks 2 and 3 as described below. Task 2: chemistry of pretreatment. This Quarter they continued their investigation of the chemistry of pretreatment using an iron catalyst, (ferrous sulfate), both with and without aqueous pretreatment on Wyodak coal. The combination of iron and hydrothermal pretreatment gave the best results, as long as the pretreated coal was not dried prior to conversion. However, the combination of iron and pretreatment gave similar conversions as with pretreatment alone. Task 3: chemistry of synergy. To help provide a baseline for distinguishing between the benefits resulting from chemical and physical solvency factors, the authors decided to conduct some experiments in homogeneous systems, from which they can easily extract the impact due to chemical changes. They synthesized a series of benzyl aromatics and studied their cleavage in a mixture of anthracene and dihydroanthracene. Cleavage rates for the different substrates increase ...

Description: The objectives of this project are to: (1) study the scope of hydrothermal pretreatment of coal on subsequent conversion, (2) identify and study the chemical or physical causes of this effect, and (3) attempt to elucidate the chemistry responsible for any coal-resid synergisms. This project is divided into three tasks. This quarter the authors concentrated on Tasks 1 and 2 as described below. Task 1: scope of hydrothermal pretreatment. The report contains a preprint submitted to the upcoming ACS meeting in Atlanta describing efforts to evaluate the aqueous pretreatment effect. The results showed that the aqueous pretreatment techniques at 350 C were most effective for the Wyodak coal, with the lignite showing a slight benefit, and the Illinois {number_sign}6 coal showing essentially no benefit. Task 2: chemistry of pretreatment. This quarter the authors investigated the chemistry of pretreatment using labeled water. In particular, catechol that was treated with and without kaolin and H{sub 2}{sup 18}O and was found to have labeled oxygen incorporation. They are aware of no precedents for such a reaction, and suspect that the exchange comes about from an intermediate step where the catechol dimerizes and can lose water in a reversible step. They further suspect that ...

An Exploratory Energy Analysis of Electrochromic Windows in Small and Medium Office Buildings - Simulated Results Using EnergyPlus

An Exploratory Energy Analysis of Electrochromic Windows in Small and Medium Office Buildings - Simulated Results Using EnergyPlus

Date: August 1, 2010
Creator: Belzer, David B.
Description: The Department of Energy’s (DOE) Building Technologies Program (BTP) has had an active research program in supporting the development of electrochromic (EC) windows. Electrochromic glazings used in these windows have the capability of varying the transmittance of light and heat in response to an applied voltage. This dynamic property allows these windows to reduce lighting, cooling, and heating energy in buildings where they are employed. The exploratory analysis described in this report examined three different variants of EC glazings, characterized by the amount of visible light and solar heat gain (as measured by the solar heat gain coefficients [SHGC] in their “clear” or transparent states). For these EC glazings, the dynamic range of the SHGC’s between their “dark” (or tinted) state and the clear state were: (0.22 - 0.70, termed “high” SHGC); (0.16 - 0.39, termed “low” SHGC); and (0.13 - 0.19; termed “very low” SHGC). These glazings are compared to conventional (static) glazing that meets the ASHRAE Standard 90.1-2004 energy standard for five different locations in the U.S. All analysis used the EnergyPlus building energy simulation program for modeling EC windows and alternative control strategies. The simulations were conducted for a small and a medium office building, where engineering ...

Description: A strong need exists today for more efficient energy-conversion systems. Our reliance on limited fuel resources, such as petroleum for the majority of our energy needs makes it imperative that we utilize these resources as efficiently as possible. Higher-efficiency energy conversion also means less pollution, since less fuel is consumed and less exhaust created for the same energy output. Additionally, for many industrialized nations, such as the United States which must rely on petroleum imports, it is also imperative from a national-security standpoint to reduce the consumption of these precious resources. A substantial reduction of U.S. oil imports would result in a significant reduction of our trade deficit, as well as costly military spending to protect overseas petroleum resources. Therefore, energy-conversion devices which may utilize alternative fuels are also in strong demand. This paper describes research on fuel cells for transportation.
