Superefficient Refrigerators: Opportunities and Challenges for Efficiency Improvement Globally

Energy Technology Data Exchange (ETDEWEB)

Shah, Nihar; Park, Won Young; Bojda, Nicholas; McNeil, Michael A.

2014-08-01

As an energy-intensive mainstream product, residential refrigerators present a significant opportunity to reduce electricity consumption through energy efficiency improvements. Refrigerators expend a considerable amount of electricity during normal use, typically consuming between 100 to 1,000 kWh of electricity per annum. This paper presents the results of a technical analysis done for refrigerators in support of the Super-efficient Equipment and Appliance Deployment (SEAD) initiative. Beginning from a base case representative of the average unit sold in India, we analyze efficiency improvement options and their corresponding costs to build a cost-versus-efficiency relationship. We then consider design improvement options that are known to be the most cost effective and that can improve efficiency given current design configurations. We also analyze and present additional super-efficient options, such as vacuum-insulated panels. We estimate the cost of conserved electricity for the various options, allowing flexible program design for market transformation programs toward higher efficiency. We estimate ~;;160TWh/year of energy savings are cost effective in 2030, indicating significant potential for efficiency improvement in refrigerators in SEAD economies and China.

14 MeV proton activation analysis

International Nuclear Information System (INIS)

Constantinescu, B.; Ivanov, E.; Plostinaru, D.; Popa-Nemoiu, A.; Pascovichi, G.

1985-01-01

A fast nuclear nondestructive method for protein analysis using the 14 MeV proton activation has been developed. The total nitrogen content was measured through the reaction: 14 N (p,n) 14 O, (Tsub(1/2)=71 s). The 14 O activity was detected by means of its characteristic 2.312 MeV gamma-ray line with a NaI(Tl) detector. For a fast determination of a large number of samples a mechanized sistem reacting a rate of one sample per minute has been developed. The laboratory electronics comprises a multichannel analyser, a PDP computer and an electronic module comtroller. Comparison of the results obtained by the method described and the classical Kjeldal technique for samples of various cereal grains (soya bean seads, wheat, barley and corn) showed good correlation. A problem of the analysis of the whole protein region on corn and soya-bean seads, where this region is thicker (0,2 - 2 mm), is mentioned. In this case flour was proposed to be used to obtain a protein homogeneous sample and the irradiaton dose for a sample was about 33,000 Gy, mainly (99%) from protons (27 s x 100 nA x 14 MeV)

Opening Data in the Long Tail for Community Discovery, Curation and Action Using Active and Social Curation

Science.gov (United States)

Hedstrom, M. L.; Kumar, P.; Myers, J.; Plale, B. A.

2012-12-01

In data science, the most common sequence of steps for data curation are to 1) curate data, 2) enable data discovery, and 3) provide for data reuse. The Sustainable Environments - Actionable Data (SEAD) project, funded through NSF's DataNet program, is creating an environment for sustainability scientists to discover data first, reuse data next, and curate data though an on-going process that we call Active and Social Curation. For active curation we are developing tools and services that support data discovery, data management, and data enhancement for the community while the data is still being used actively for research. We are creating an Active Content Repository, using drop box, semantic web technologies, and a Flickr-like interface for researchers to "drop" data into a repository where it will be replicated and minimally discoverable. For social curation, we are deploying a social networking tool, VIVO, which will allow researchers to discover data-publications-people (e.g. expertise) through a route that can start at any of those entry points. The other dimension of social curation is developing mechanisms to open data for community input, for example, using ranking and commenting mechanisms for data sets and a community-sourcing capability to add tags, clean up and validate data sets. SEAD's strategies and services are aimed at the sustainability science community, which faces numerous challenges including discovery of useful data, cleaning noisy observational data, synthesizing data of different types, defining appropriate models, managing and preserving their research data, and conveying holistic results to colleagues, students, decision makers, and the public. Sustainability researchers make significant use of centrally managed data from satellites and national sensor networks, national scientific and statistical agencies, and data archives. At the same time, locally collected data and custom derived data products that combine observations and

The contents of five platinum-group metals (Ru, Rh, Pd, Ir, and Pt) in soils and street dust of the Southeastern administrative district (SEAD) of Moscow have been determined. The contents of these elements in soils may considerably exceed their natural abundances in the lithosphere and are characterized by considerable variability and asymmetric frequency distribution. A close correlation between Rh, Pd, and Pt contents in soils and street dust has been shown. The data on the contents of the elements and the ratios between them suggest that motor vehicles are the major source of pollution of soils and street dust in the studied district.

Extracolic-infiltrative lesions of the sigmoid colon and recto-sigmoid junction

Krestin, G.P.; Beyer, D.; Lorenz, R.

1983-01-01

The problems of extracolic-infiltrative lesions of the sigmoid colon and recto-sigmoid junction are discussed, based on representative case studies. Because of the localisation of these bowel segments in the lower peritoneal cavity, they can be reached by direct infiltration of contiguous tumors - especially carcinoma of the ovary - or by seading into the pouch of Douglas and the sigmoid mesocolon. In many cases characteristic roentgen-morphologic features indicate a secondary infiltration, but inflammatory and malignant lesions have to be differentiated. The differential-diagnosis must consider also diverticulitis, endometriosis and extracolic growth of colonic carcinoma. Additional ultrasonography and computed tomography may help to clear topographical relations and to detect direct and indirect signs of peritoneal carcinomatosis and abscess. (orig.)

At a low temperature of 450 degrees C, ZnS nanoribbons have been synthesized on Si and KCl substrates by a simple chemical vapor deposition (CVD) method with a two-temperature-zone furnace. Zinc and sulfur powders are used as sources in the different temperature zones. X-ray diffraction (XRD), selected area electron diffraction (SEAD), and transmission electron microscopy (TEM) analysis show that the ZnS nanoribbons are the wurtzite structure, and there are two types-single-crystal and bicrystal nanoribbons. Photoluminescence (PL) spectrum shows that the spectrum mainly includes two parts: a purple emission band centering at about 390 nm and a blue emission band centering at about 445 nm with a weak green shoulder around 510 nm.

Cea and AREVA NP have engaged an extensive research and development program on HTR (high temperature reactor) fuel. The improving of safety of (very) high temperature reactors (V/HTR) is based on the quality of the fuel particles. This requires a good knowledge of the properties of the four-layers TRISO particles designed to retain the uranium and fission products during irradiation or accident conditions. The aim of this work is to characterize exhaustively the structure and the thermomechanical properties of each unirradiated layer (silicon carbide and pyrocarbon coatings) by electron microscopy (SEM, TEM), selected area electronic diffraction (SEAD), thermo reflectance microscopy and nano-indentation. The long term objective of this study is to define pertinent parameters for fuel performance codes used to better understand the thermomechanical behaviour of the coated particles. (authors)

Lanthanum-modified lead zirconate titanate Pb 1-x La x (Zr 1-y Ti y )O 3 (PLZT) hollow nanospheres have been successfully prepared via a template-free hydrothermal method using the well-mixed coprecipitated precursors and the KOH mineralizer. The structure, composition, and morphology of the PLZT hollow nanospheres were characterized by XRD (X-ray diffraction), ICP (inductive coupled plasma emission spectrometer), FTIR (Fourier transform infrared spectra), TG/DTA (thermogravimetric analysis and differential thermal analysis), TEM (transmission electron microscopy) and SEAD (selected area diffraction). The results show that the composition and the morphology control of the PLZT products are determined by the KOH concentration. The PLZT hollow nanospheres with uniform size of about 4 nm were synthesized in the presence of 5 M KOH. The crystalline nanoparticles can be prepared at dilute KOH, in contrast to the amorphous powders prepared at concentrated KOH. Formation mechanisms of the PLZT hollow nanospheres are also discussed.

Improving the oxidation resistance and stability of Ag nanoparticles by coating with multilayered reduced graphene oxide

Science.gov (United States)

Li, Yahui; Zhang, Huayu; Wu, Bowen; Guo, Zhuo

2017-12-01

A kind of coating nanostructure, Ag nanoparticles coated with multilayered reduced graphene oxide (RGO), is fabricated by employing a three-step reduction method in an orderly manner, which is significantly different from the conventional structures that are simply depositing or doping with Ag nanoparticles on RGO via chemical reduction. The as-prepared nanostructure is investigated by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), selected-area electronic diffraction (SEAD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). The results show that the obtained Ag/RGO nanostructure is observed to be a perfect coating structure with well dispersed Ag particles, which is responsible for the remarkable oxidation resistance. The results of XPS spectra indicate the content of metallic Ag is far greater than that of Ag oxides despite of prolonged exposure to the air, which fully demonstrate the excellent stability of thus coating nanostructure.

With rising global emphasizes on climate change and sustainable development, how to accelerate the transformation of energy efficiency has become an important question. Designing and implementing energy-efficiency policies for super-efficient products represents an important direction to achieve breakthroughs in the field of energy conservation. On December 31, 2014, China’s National Development and Reform Commission (NDRC) jointly six other ministerial agencies launched China Leading Energy Efficiency Program (LEP), which identifies top efficiency models for selected product categories. LEP sets the highest energy efficiency benchmark. Design of LEP took into consideration of how to best motivate manufacturers to accelerate technical innovation, promote high efficiency products. This paper explains core elements of LEP, such as objectives, selection criteria, implementation method and supportive policies. It also proposes recommendations to further improve LEP through international policy comparison with Japan’s Top Runner Program, U.S. Energy Star Most Efficient, and SEAD Global Efficiency Medal.

problem domain by establishing an effective means to communicate the semantics from the RAAM framework. These techniques make it possible to include diverse multi-metric models within the RAAM framework in addition to system and operational level trades. A canonical example was used to explore the uses of the methodology. The canonical example contains all of the features of a full system of systems architecture analysis study but uses fewer tasks and systems. Using RAAM with the canonical example it was possible to consider both system and operational level trades in the same analysis. Once the methodology had been tested with the canonical example, a Suppression of Enemy Air Defenses (SEAD) capability model was developed. Due to the sensitive nature of analyses on that subject, notional data was developed. The notional data has similar trends and properties to realistic Suppression of Enemy Air Defenses data. RAAM was shown to be traceable and provided a mechanism for a unified treatment of a variety of metrics. The SEAD capability model demonstrated lower computer runtimes and reduced model creation complexity as compared to methods currently in use. To determine the usefulness of the implementation of the methodology on current computing hardware, RAAM was tested with system of system architecture studies of different sizes. This was necessary since system of systems may be called upon to accomplish thousands of tasks. It has been clearly demonstrated that RAAM is able to enumerate and evaluate the types of large, complex design spaces usually encountered in capability based design, oftentimes providing the ability to efficiently search the entire decision space. The core algorithms for generation and evaluation of alternatives scale linearly with expected problem sizes. The SEAD capability model outputs prompted the discovery a new issue, the data storage and manipulation requirements for an analysis. Two strategies were developed to counter large data sizes, the use

Novel nanocomposites of carbon nanotubes supported porous VO(x)N(y) nonoribbons (VO(x)N(y)-CNTs) have been synthesized by the annealing of the sol-gel mixture of CNTs and V2O5 under NH3 atmosphere as well as the ageing process in air. Besides the morphological and structural characterizations revealed by TEM, SEAD, EDS, XRD and XPS measurements, typical electrochemical tests including cyclic voltammetry (CV), rotating disk electrode (RDE) and chronoamperometry have been employed to determine the oxygen reduction reaction (ORR) performance of VO(x)N(y)-CNTs. Inspiringly, the results indicate that VO(x)N(y)-CNTs catalyst exhibits a 0.4 mA/cm(2) larger diffusion-limited current density, a 0.10  V smaller onset potential value, a 10.73% less of ORR current decay and an excellent methanol-tolerance compared with commercial Pt/C catalyst. Therefore, we have reasonable grounds to believe that this new VO(x)N(y)-CNTs nanocomposites can be regarded as a promising non-precious methanol-tolerant ORR catalyst candidate for alkaline fuel cells.

A base empírica é composta por séries da Pesquisa de Emprego e Desemprego (PED na Região Metropolitana de São Paulo, realizada pela Fundação Seade. Os dados revelam que, em 2009, havia cerca de 100.000 comerciantes de rua trabalhando na capital paulista, número bem menor do que o verificado em 2004 (133.000 pessoas. Essa significativa redução deve ser atribuída à melhoria do mercado de trabalho metropolitano depois de 2004, expressa pela queda do desemprego. Não obstante a heterogeneidade dos comerciantes de rua, foi possível identificar um perfil predominante desses trabalhadores: são homens, de cor branca, de idade madura, com precária escolaridade, chefes de domicílios pobres e moradores há bastante tempo na cidade.

Full Text Available O propósito do presente trabalho é avaliar a evolução da mortalidade neonatal em São Luís nos últimos 18 anos, classificá-la de acordo com os dias de vida e pelo critério de evitabilidade de óbitos da Fundação SEADE, a partir de dados do IBGE e do Ministério da Saúde. Detectou-se aumento da mortalidade neonatal, às custas de aumento expressivo do seu componente precoce, especialmente pelas causas reduzíveis por diagnóstico e tratamento precoce, e parcialmente reduzíveis por adequado controle da gravidez. A mortalidade infantil, desse modo, manteve-se inalterada, apesar do decréscimo do seu componente pós-neonatal. O aumento expressivo no coeficiente de mortalidade neonatal a partir de 1995 aponta para a queda na qualidade da assistência obstétrica e neonatal, talvez motivada pelo elevado percentual de cesáreas e pela superlotação dos berçários. A tendência de estabilidade ou aumento da mortalidade neonatal é semelhante à observada recentemente no Brasil como um todo e difere da observada em outras cidades brasileiras, nas quais foi descrita queda lenta, mas persistente, da mortalidade neonatal, em oposição a uma redução mais dramática em países desenvolvidos.This study examined neonatal mortality trends in São Luís in the last 18 years. The early and late components were assessed and causes were classified according to SEADE Foundation criteria based on reducibility of deaths and timing of prevention (during prenatal care, childbirth, or neonatal care. Data were derived from official live birth and death records. We detected an unexpected increase in the neonatal mortality rate, due primarily to a steep rise in early neonatal deaths. Causes reducible by early diagnosis and treatment (other specific infections and other neonatal respiratory causes and those partially reducible by adequate monitoring of pregnancy (preterm births, low birth weight, and respiratory distress syndrome showed the largest increase

MnBi is a rare-earth free high-energy magnetic material useful for the permanent magnet based devices. In a simple method, a MnBi alloy was prepared by arc melting method using Mn and Bi metals in 60:40 atomic ratio. In terms of the X-ray diffraction, a crystalline MnBi phase is formed with Bi as impurity phase of the as-prepared alloy. FESEM image of chemically etched sample shows small grains throughout the alloy. SEAD pattern and lattice image were studied to understand the internal microstructure of the alloy. The thermomagnetic curves measured in ZFC-FC cycles over 5-380 K temperatures at 500 Oe field, shows the induced magnetization of 5-25 % in the sample. The coercivity values, 7.455 kOe (13.07 emu/g magnetization) at 380 K, and 5.185k Oe (14.75 emu/g magnetization) at 300 K, are observed in the M-H hysteresis loops. A decreased value 0.181kOe (18.05 emu/g magnetization) appears at 100 K due to the change in the magnetocrystalline anisotropy. The results are useful to fabricate small MnBi magnets for different permanent magnets based devices.

Country Review of Energy-Efficiency Financial Incentives in the Residential Sector

Energy Technology Data Exchange (ETDEWEB)

Can, Stephane de la Rue du; Shah, Nihar; Phadke, Amol

2011-07-13

A large variety of energy-efficiency policy measures exist. Some are mandatory, some are informative, and some use financial incentives to promote diffusion of efficient equipment. From country to country, financial incentives vary considerably in scope and form, the type of framework used to implement them, and the actors that administer them. They range from rebate programs administered by utilities under an Energy-Efficiency Resource Standards (EERS) regulatory framework (California, USA) to the distribution of Eco-points rewarding customers for buying highly efficient appliances (Japan). All have the primary objective of transforming the current market to accelerate the diffusion of efficient technologies by addressing up-front cost barriers faced by consumers; in most instances, efficient technologies require a greater initial investment than conventional technologies. In this paper, we review the different market transformation measures involving the use of financial incentives in the countries belonging to the Major Economies Forum. We characterize the main types of measures, discuss their mechanisms, and provide information on program impacts to the extent that ex-ante or ex-post evaluations have been conducted. Finally, we identify best practices in financial incentive programs and opportunities for coordination between Major Economies Forum countries as envisioned under the Super Efficient Appliance Deployment (SEAD) initiative.

description, the DCS instance will be able to provide default mappings for the directories and files within the package payload and enable support for deposited content at a lower level of service. Internally, the DCS will map these hybrid package serializations to its own internal business objects and their properties. Thus, this approach is highly extensible, as other packaging formats could be mapped in a similar manner. In addition, this scheme supports establishing the fixity of the payload while still supporting update of the semantic overlay data. This allows a data producer with scarce resources or an archivist who acquires a researcher's data to package the data for deposit with the intention of augmenting the resource description in the future. The Data Conservancy is partnering with the Sustainable Environment Actionable Data[4] project to test the interoperability of this new packaging mechanism.

The research work involves the development of better and reliable method for the bio-fabrication of Zinc oxide nanoparticles through green method using Moringa Oleifera extract as an effective chelating agent. The electrochemical activity, crystalline structure, morphology, isothermal behavior, chemical composition and optical properties of ZnO nanoparticles were studied using various characterization techniques i.e. Cyclic voltammetry (CV), X-ray powder diffraction (XRD), High resolution transmission electron microscopy (HRTEM), Selected area electron diffraction (SEAD), Differential scanning calorimetry/thermogravimetric analysis (DSC/TGA), Fourier Transform Infrared analysis (FTIR) and Ultraviolet spectroscopy studies (UV-vis). The electrochemical analysis proved that the ZnO nano has high electrochemical activity without any modifications and therefore are considered as a potential candidate in electrochemical applications. The XRD pattern confirmed the crystallinity and pure phase of the sample. DSC/TGA analysis of ZnO sample (before anneal) revealed three endothermic peaks around 140.8 °C, 223.7 °C and 389.5 °C. These endothermic peaks are attributed to the loss of volatile surfactant, conversion of zinc hydroxide to zinc oxide nanoparticles and transformation of zinc oxide into zinc nanoparticles. Mechanisms of formation of the ZnO nanoparticles via the chemical reaction of the Zinc nitrate precursor with the bioactive compounds of the Moringa oleifera are proposed for each of the major family compounds: Vitamins, Flavonoids, and Phenolic acids.

In order to train personnel inn order to train personnel in Embalse Nuclear Power Plant, and provided that such training given primarily on the location of such a facility, we designed a pedagogical strategy that combined the use of conventional resources with new information technologies. Since the Nuclear Reactor RA-0 is an ideal tool for teaching Reactor Physics, priority was the use of it, both locally remotely. The teaching strategy is based on four pillar: -Lectures on the Power Plant (using a virtual classroom to support); -Remote monitoring of Ra-0 Nuclear Reactor parameters while operating (RA0REMOTO); -Use, through the Internet, of the Ra-0 Nuclear Reactor Simulator (RA0SIMUL); -Made in the Nuclear Reactor RA-0 of Reactor Physics practical. The work emphasizes RA0REMOTO and RA0SIMUL systems. The RA0REMOTO system is an appendix of the Electronic Data Acquisition System (SEAD) of the Nuclear Reactor RA-0. This system acquires signals from Reactor instrumentation and sends them to a server running the software that 'publish' the reactor parameters on the internet. Students may, during the lectures, monitor any parameter of the reactor while it operates, which allows teachers to compare theory with reality. RA0SIMUL is a simulator on the RA-0, which allows students to 'operate' a reactor analyzing the underlying physics concepts (author)

Effective long-term curation and preservation of data for community use has historically been limited to high-value and homogeneous collections produced by mission-oriented organizations. The technologies and practices that have been applied in these cases, e.g. relational data bases, development of comprehensive standardized vocabularies, and centralized support for reference data collections, are arguably applicable to the much broader range of data generated by the long tail of investigator-led research, with the logical conclusion of such an argument leading to the call for training, evangelism, and vastly increased funding as the best means of broadening community-scale data management. In this paper, we question this reasoning and explore how alternative approaches focused on the overall data lifecycle and the sociological and business realities of distributed multi-disciplinary research communities might dramatically lower costs, increase value, and consequently drive dramatic advances in our ability to use and re-use data, and ultimately enable more rapid scientific advance. Specifically, we introduce the concepts of active and social curation as a means to decrease coordination costs, align costs and values for individual data producers and data consumers, and improve the immediacy of returns for data curation investments. Further, we describe the specific architecture and services for active and social curation that are being prototyped within the Sustainable Environment - Actionable Data (SEAD) project within NSF's DataNet network and discuss how they are motivated by the long-tail dynamics in the cross-disciplinary sustainability research community.

Data curation underpins data-driven scientific advancements. It manages the information flux across multiple users throughout data life cycle as well as increases data sustainability and reusability. The exponential growth in data production spanning across the Earth Science involving individual and small research groups, which is termed as log-tail data, increases the data-knowledge latency among related domains. It has become clear that an advanced framework-agnostic metadata and ontologies for long-tail data is required to increase their visibility to each other, and provide concise and meaningful descriptions that reveal their connectivity. Despite the advancement that has been achieved by various sophisticated data management models in different Earth Science disciplines, it is not always straightforward to derive relationships among long-tail data. Semantic data clustering algorithms and pre-defined logic rules that are oriented toward prediction of possible data relationships, is one method to address these challenges. Our work advances the connectivity of related long-tail data by introducing the design for an ontology-based knowledge management system. In this work, we present the system architecture, its components, and illustrate how it can be used to scrutinize the connectivity among datasets. To demonstrate the capabilities of this "data network" prototype, we implemented this approach within the Sustainable Environment Actionable Data (SEAD) environment, an open-source semantic content repository that provides a RDF database for long-tail data, and show how emergent relationships among datasets can be identified.

In the present paper, Laser Raman spectral was used to study the carbon structure of LiFePO4/C positive material. The samples were also been characterized by X-ray diffraction (XRD), scanning electron microscope(SEM), selected area electron diffraction (SEAD) and resistivity test. The result indicated that compared with the sp2/sp3 peak area ratios the I(D)/I(G) ratios are not only more evenly but also exhibited some similar rules. However, the studies indicated that there exist differences of I(D)/ I(G) ratios and sp2/sp3 peak area ratios among different points in the same sample. And compared with the samples using citric acid or sucrose as carbon source, the sample which was synthetized with mixed carbon source (mixed by citric acid and sucrose) exhibited higher I(D)/I(G) ratios and sp2/sp3 peak area ratios. Also, by contrast, the differences of I(D)/I(G) ratios and sp2/sp3 peak area ratios among different points in the same sample are less than the single carbon source samples' datas. In the scanning electron microscopy (sem) and transmission electron microscopy (sem) images, we can observed the uneven distributions of carbon coating of the primary particles and the secondary particles, this may be the main reason for not being uniform of difference data in the same sample. The obvious discreteness will affect the normal use of Raman spectroscopy in these tests.

in the Sustainable Environments - Actionable Data (SEAD) project, an NSF funded DataNet partner, for reducing the burden of describing, publishing, and sharing research data. We use as example the university institutional repository (IR) and an application taken from climate studies. The application is a storm surge model running as a cloud-based software as a service (SaaS). One of the more immediate and dangerous impacts of climate change could be change in the strength of storms that form over the oceans. There have already been indications that even modest changes in ocean surface temperature can have a disproportionate effect on hurricane strength. In an effort to understand these impacts, modelers turn to predictions generated by hydrodynamic coastal ocean models such as the Sea, Lake and Overland Surges from Hurricanes (SLOSH) model. We step through a use scenario of SLOSH in emergency management. To publish a newly created data set resulting from the ensemble runs on the cloud, one needs tools that minimize the burden of describing the data. SEAD has such tools, and engages the e-Science data curation librarian in the process to aid the data set's ingest into the university IR. We finally bring attention to ongoing effort in the Research Data Alliance (RDA) to make data lifecycle issues easier for environmental researchers so that they invest less time and get more credit for their data sets, giving research wider adoption and impact.

This algorithm is based on some basic schemes such as RSA_CRT for encryption and decryption of messages; CRT for safety key generation, Shamir’s secret sharing principle for generation of secure routes. Those routes which are free from any malicious node and which belong to the set of disjoint routes between a source-destination pair are considered as probable routes. Shamir’s secret sharing principle is applied on those probable routes to obtain secure routes. Finally, most trustworthy and stable route is selected among those secure routes. Selection of the final route depends on some criteria of the nodes present in a route e.g.: battery power, mobility and trust value. In addition, complexity of key generation is reduced to a large extent by using RSA-CRT instead of RSA. In turn, the routing becomes less expensive and most secure and robust one. Performance of this routing protocol is then compared with non-secure routing protocols (AODV and DSR, secure routing scheme using secret sharing, security routing protocol using ZRP and SEAD depending on basic characteristics of these protocols. All such comparisons show that RSRP shows better performance in terms of computational cost, end-to-end delay and packet dropping in presence of malicious nodes in the MANET, keeping the overhead in terms of control packets same as other secure routing protocols.

Highlights: • Biosynthesis of ZnO nanoparticlesl by green process using Moringa Oliefera extract. • Electrochemical studies were confirmed by cyclic and Square wave voltammetry. • XRD, HRTEM, TGA/DSC, FTIR were used to characterized the nanoparticles. - Abstract: The research work involves the development of better and reliable method for the bio-fabrication of Zinc oxide nanoparticles through green method using Moringa Oleifera extract as an effective chelating agent. The electrochemical activity, crystalline structure, morphology, isothermal behavior, chemical composition and optical properties of ZnO nanoparticles were studied using various characterization techniques i.e. Cyclic voltammetry (CV), X-ray powder diffraction (XRD), High resolution transmission electron microscopy (HRTEM), Selected area electron diffraction (SEAD), Differential scanning calorimetry/thermogravimetric analysis (DSC/TGA), Fourier Transform Infrared analysis (FTIR) and Ultraviolet spectroscopy studies (UV–vis). The electrochemical analysis proved that the ZnO nano has high electrochemical activity without any modifications and therefore are considered as a potential candidate in electrochemical applications. The XRD pattern confirmed the crystallinity and pure phase of the sample. DSC/TGA analysis of ZnO sample (before anneal) revealed three endothermic peaks around 140.8 °C, 223.7 °C and 389.5 °C. These endothermic peaks are attributed to the loss of volatile surfactant, conversion of zinc hydroxide to zinc oxide nanoparticles and transformation of zinc oxide into zinc nanoparticles. Mechanisms of formation of the ZnO nanoparticles via the chemical reaction of the Zinc nitrate precursor with the bioactive compounds of the Moringa oleifera are proposed for each of the major family compounds: Vitamins, Flavonoids, and Phenolic acids.

The nano-mineralogy, petrology, and chemistry of coal gasification products have not been studied as extensively as the products of the more widely used pulverized-coal combustion. The solid residues from the gasification of a low- to medium-sulfur, inertinite-rich, volatile A bituminous coal, and a high sulfur, vitrinite-rich, volatile C bituminous coal were investigated. Multifaceted chemical characterization by XRD, Raman spectroscopy, petrology, FE-SEM/EDS, and HR-TEM/SEAD/FFT/EDS provided an in-depth understanding of coal gasification ash-forming processes. The petrology of the residues generally reflected the rank and maceral composition of the feed coals, with the higher rank, high-inertinite coal having anisotropic carbons and inertinite in the residue, and the lower rank coal-derived residue containing isotropic carbons. The feed coal chemistry determines the mineralogy of the non-glass, non-carbon portions of the residues, with the proportions of CaCO{sub 3} versus Al{sub 2}O{sub 3} determining the tendency towards the neoformation of anorthite versus mullite, respectively. Electron beam studies showed the presence of a number of potentially hazardous elements in nanoparticles. Some of the neoformed ultra-fine/nano-minerals found in the coal ashes are the same as those commonly associated with oxidation/transformation of sulfides and sulfates. - Highlights: • Coal waste geochemisty can provide increased environmental information in coal-mining areas. • Oxidation is the major process for mineral transformation in coal ashes. • The electron bean methodology has been applied to investigate neoformed minerals.

SAS- Semantic Annotation Service for Geoscience resources on the web

There is a growing need for increased integration across the data and model resources that are disseminated on the web to advance their reuse across different earth science applications. Meaningful reuse of resources requires semantic metadata to realize the semantic web vision for allowing pragmatic linkage and integration among resources. Semantic metadata associates standard metadata with resources to turn them into semantically-enabled resources on the web. However, the lack of a common standardized metadata framework as well as the uncoordinated use of metadata fields across different geo-information systems, has led to a situation in which standards and related Standard Names abound. To address this need, we have designed SAS to provide a bridge between the core ontologies required to annotate resources and information systems in order to enable queries and analysis over annotation from a single environment (web). SAS is one of the services that are provided by the Geosematnic framework, which is a decentralized semantic framework to support the integration between models and data and allow semantically heterogeneous to interact with minimum human intervention. Here we present the design of SAS and demonstrate its application for annotating data and models. First we describe how predicates and their attributes are extracted from standards and ingested in the knowledge-base of the Geosemantic framework. Then we illustrate the application of SAS in annotating data managed by SEAD and annotating simulation models that have web interface. SAS is a step in a broader approach to raise the quality of geoscience data and models that are published on the web and allow users to better search, access, and use of the existing resources based on standard vocabularies that are encoded and published using semantic technologies.

ARC-VM: An architecture real options complexity-based valuation methodology for military systems-of-systems acquisitions

Science.gov (United States)

Domercant, Jean Charles

The combination of today's national security environment and mandated acquisition policies makes it necessary for military systems to interoperate with each other to greater degrees. This growing interdependency results in complex Systems-of-Systems (SoS) that only continue to grow in complexity to meet evolving capability needs. Thus, timely and affordable acquisition becomes more difficult, especially in the face of mounting budgetary pressures. To counter this, architecting principles must be applied to SoS design. The research objective is to develop an Architecture Real Options Complexity-Based Valuation Methodology (ARC-VM) suitable for acquisition-level decision making, where there is a stated desire for more informed tradeoffs between cost, schedule, and performance during the early phases of design. First, a framework is introduced to measure architecture complexity as it directly relates to military SoS. Development of the framework draws upon a diverse set of disciplines, including Complexity Science, software architecting, measurement theory, and utility theory. Next, a Real Options based valuation strategy is developed using techniques established for financial stock options that have recently been adapted for use in business and engineering decisions. The derived complexity measure provides architects with an objective measure of complexity that focuses on relevant complex system attributes. These attributes are related to the organization and distribution of SoS functionality and the sharing and processing of resources. The use of Real Options provides the necessary conceptual and visual framework to quantifiably and traceably combine measured architecture complexity, time-valued performance levels, as well as programmatic risks and uncertainties. An example suppression of enemy air defenses (SEAD) capability demonstrates the development and usefulness of the resulting architecture complexity & Real Options based valuation methodology.

A software package, Sectoral Energy/Employment Analysis and Data System (SEADS-PC), that can translate policy changes into employment and energy impacts is described. The core data for this tool include input-output (I/O) tables for 1977, 1982, 1987, and 2005 in 1982 dollars, and I/O tables for 1987 and 1990 in 1987 dollars. For each of the I/O tables there are corresponding final demand vectors and employment intensities. For a but the 2005 table there are energy intensities as well. The final demands and the intensities can be changed to reflect alternative policies. A final demand vector that reflects a specific policy, for example, can be created, based on an existing final demand vector. This vector can then be premultiplied by the appropriate I/O table to yield industry output, which in turn can be multiplied by energy or employment intensities to yield employment or energy resulting from the policy scenario. These policy results can then be compared with a base case and the differences reported. The report is in four sections. The first section is an introduction. The second section provides the accounting framework for the tool and describes the data provided. The third section serves as a user`s guide to the software, describing the functionality of the program and what results can be expected. The fourth section uses the President`s Climate Change Action Plan (CCAP) as an example policy for which employment impacts can be calculated. The results of the CCAP exercise suggest that this program will result in about 60,000 new jobs (about 115 million additional hours of work) for the year 2000. In the year 2000, the CCAP final demands are greater than the base case final demands by $192.8 million (1990 dollars). The additional jobs are created as a result of both the shifts among final demand categories and a slight increase in economic activity.

This document illustrates the key issues and considerations involved in implementing energy-efficient public procurement. Our primary sources of information have been our partners in the Super Efficient Equipment and Appliance Deployment (SEAD) Initiative Procurement Working Group. Where applicable, we have highlighted specific ways in which working group participants have successfully overcome barriers to delivering effective programs. The following key points emerge from this analysis of programs for energy-efficient public procurement. Lessons for both developed and developing programs are highlighted throughout the guide. 1. Policy: Policy provides the initiative to begin a transition from first cost to life-cycle cost based purchasing methods and culture. Effective policy is well-communicated, establishes accountability from top to bottom of organizations and simplifies the processes necessary to comply. Flexibility and responsiveness are essential in policy development and implementation. Mandatory and voluntary policies may complement one another. 2. Procurement Criteria: Procurement staff must be confident that energy-efficient procurement criteria offer the best long-term value for their organization’s money and represent real environmental gains. Involving multiple stakeholders at the early stages of the criteria creation process can result in greater levels of cooperation from private industry. Criteria should make comparison of products easy for purchasers and require minimal additional calculations. Criteria will need to be regularly updated to reflect market developments. 3. Training: Resources for the creation of training programs are usually very limited, but well-targeted training is necessary in order for a program to be effective. Training must emphasize a process that is efficient for purchasers and simplifies compliance. Purchaser resources and policy must be well designed for training to be effective. Training program development is an

Geo-Semantic Framework for Integrating Long-Tail Data and Model Resources for Advancing Earth System Science

Science.gov (United States)

Elag, M.; Kumar, P.

Often, scientists and small research groups collect data, which target to address issues and have limited geographic or temporal range. A large number of such collections together constitute a large database that is of immense value to Earth Science studies. Complexity of integrating these data include heterogeneity in dimensions, coordinate systems, scales, variables, providers, users and contexts. They have been defined as long-tail data. Similarly, we use "long-tail models" to characterize a heterogeneous collection of models and/or modules developed for targeted problems by individuals and small groups, which together provide a large valuable collection. Complexity of integrating across these models include differing variable names and units for the same concept, model runs at different time steps and spatial resolution, use of differing naming and reference conventions, etc. Ability to "integrate long-tail models and data" will provide an opportunity for the interoperability and reusability of communities' resources, where not only models can be combined in a workflow, but each model will be able to discover and (re)use data in application specific context of space, time and questions. This capability is essential to represent, understand, predict, and manage heterogeneous and interconnected processes and activities by harnessing the complex, heterogeneous, and extensive set of distributed resources. Because of the staggering production rate of long-tail models and data resulting from the advances in computational, sensing, and information technologies, an important challenge arises: how can geoinformatics bring together these resources seamlessly, given the inherent complexity among model and data resources that span across various domains. We will present a semantic-based framework to support integration of "long-tail" models and data. This builds on existing technologies including: (i) SEAD (Sustainable Environmental Actionable Data) which supports curation

Gastric and colorectal cancer mortality in an urban and industrialized area of Brazil Mortalidade por cânceres gástrico e colorretal em uma área urbana-industrial do Brasil

Full Text Available PURPOSE: To study the gastric and colorectal cancer mortalities and their relation to the urban-industrialization in Baixada Santista, located in the southeastern region of Brazil. METHODS: Selected from the registries of the State System of Data Analysis Foundation (SEADE were 1105 deaths due to gastric cancer (ICD 153--154 and 690 due to colorectal cancer (ICD 151 that occurred from 1980 to 1993 in males, above 10 years of age, residing in Baixada Santista. For each of these types of cancer, the standardized mortality rates, age-adjusted by world population in the 1960s, for 4 industrialized and 4 non-industrialized urban communities in that region were calculated. The ratios among those rates were calculated in order to compare the mortality in the periods 1980--93, 1980--1986, and 1987--1993. RESULTS: Standardized mortality rates for colorectal cancer were significantly higher in industrialized area, with ratios of 1.6 [95% CI 1.22 -- 2.29], 1.6 [95% CI 1.2 -- 2.0], and 1.6 [95% CI 1.3 -- 2.0] in the periods 1980--86, 1987--1993 and 1980--93, respectively. Gastric cancer did not show any statistical difference between the industrialized and non-industrialized areas, but there was a significant decrease in BS from the period 1980--1986 to 1987--1993. CONCLUSIONS: The significant elevation of colorectal cancer mortality in the industrialized area could be related to exposure to numerous carcinogens such as aromatic hydrocarbon, organic-chloride, metals, and industrial-port dust present in the region. Alternatively, the non-significant difference in gastric cancer between industrialized and non-industrialized areas and significant decrease in the last few years could be predominately reflecting the advances in the quality of life in urban areas. These results require further case-control studies that could help with the analysis of the associations among cancer and environmental factors (occupational, urban-industrial, habit, and life condition

Highlights: • Intrinsic ferromagnetism in electrospun nanofibers of Ce{sub 0.96}Fe{sub 0.04}O{sub 2} is reported. • The prepared samples were well characterized by XRD, TEM, XANES, XPS, and VSM. • Ce{sub 0.96}Fe{sub 0.04}O{sub 2} samples are ferromagnetic having Ms of 0.002–0.923 emu/g at 10 kOe. • Oxygen vacancies play an important role to induce room temperature ferromagnetism. • Ferromagnetism observed in Ce{sub 0.96}Fe{sub 0.04}O{sub 2} is intrinsic. - Abstract: We report room temperature ferromagnetism in ∼30–60 nm nanofibers of Ce{sub 0.96}Fe{sub 0.04}O{sub 2} calcined at 500, 600, 700, and 800 °C. The as-spun nanofibers were fabricated by electrospinning technique. Nanofibers of the as-spun and calcined samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), X-ray absorption spectroscopy (XAS), and vibrating sample magnetometer (VSM). The XRD and TEM with selected electron diffraction (SEAD) analysis results indicate that the Ce{sub 0.96}Fe{sub 0.04}O{sub 2} nanofibers have a cubic perovskite structure without any secondary phase. The as-spun samples exhibit a diamagnetic behavior, whereas the calcined Ce{sub 0.96}Fe{sub 0.04}O{sub 2} samples are ferromagnetic having the specific magnetizations of 0.002–0.923 emu/g at 10 kOe. The results from XAS spectra show the valence state of Fe{sup 3+} and Fe{sup 2+} mixed in the Ce{sub 0.96}Fe{sub 0.04}O{sub 2} samples indicating oxygen vacancies in the nanofibers. Similarly, the results XPS spectra show that there are oxygen vacancies in the nanofibers as a result of Ce{sup 3+} on the surface. These oxygen vacancies play an important role to induce room temperature ferromagnetism (RT-FM) in the calcined Ce{sub 0.96}Fe{sub 0.04}O{sub 2} nanofibers. Our results indicate that the ferromagnetic properties of Ce{sub 0.96}Fe{sub 0.04}O{sub 2} system are intrinsic and are not a result of

The adapted form of the instrument has been applied in a sample of 2725 adolescents from all regions of SP City, males and females, from 11 to 19 years, categorized by their social vulnerability (IPVS, SEADE, 2005 to design a map of positive values present in this population. The data showed that young people present a low number of positive values and that its variability is linked to sex and age, more than to social vulnerability. It also turns evident the necessity to review our health promotion strategies based in risk taking behaviors and grounded it in the promotion of positive values.

sets and, clearly, may lead to conclusion regarding the adequacy of the data set in general, not on individual basis. Another possibility to verify existing dose records is application of reliable retrospective dosimetric techniques, which may be used as a reference. Dosimetric screening of the study cohort requires a tool, which should meet two basic requirements: to be cheap and practical, and to be applicable to all subjects (desirably even post mortem). Till recent time such tool was missing and none of the known methods of retrospective dosimetry matched these criteria. Therefore in the novel method of Soft Expert Assessment Dosimetry (SEAD) was developed by the International Dosimetric Group operating under auspices of Ukraine-USA-France and CEC-Russia-Byelarus collaboration. This method is based on the analysis of information acquired from interviewing of liquidators and exploits regularities of dose distributions. The main advantage of this method is applicability to all subjects making it good for the screening of the cohort. Case-control study requires closer consideration of fewer subjects and in this regard high precision techniques (like EPR) make use. High cost of analyses is acceptable in this case. Practical implementation of this approach is illustrated by some on-going studies. Pros and contras of selected methods, as well as implementation considerations will be discussed as well. (author)

-makers with the ability to assess or measure the robustness of program requirements against such uncertainties. A literature review of techniques for forecasting technology performance and development uncertainties and subsequent impacts on capability, budget, and schedule requirements resulted in the conclusion that an analysis process that coupled a probabilistic analysis technique such as Monte Carlo Simulations with quantitative and parametric models of technology performance impact and technology development time and cost requirements would allow the probabilities of meeting specific constraints of these requirements to be established. These probabilities of requirements success metrics can then be used as a quantitative and probabilistic measure of program requirements robustness against technology uncertainties. Combined with a Multi-Objective Genetic Algorithm optimization process and computer-based Decision Support System, critical information regarding requirements robustness against technology uncertainties can be captured and quantified for acquisition decision-makers. This results in a more informed and justifiable selection of program technologies during initial program definition as well as formulation of program development and risk management strategies. To meet the stated research objective, the ENhanced TEchnology Robustness Prediction and RISk Evaluation (ENTERPRISE) methodology was formulated to provide a structured and transparent process for integrating these enabling techniques to provide a probabilistic and quantitative assessment of acquisition program requirements robustness against technology performance and development uncertainties. In order to demonstrate the capabilities of the ENTERPRISE method and test the research Hypotheses, an demonstration application of this method was performed on a notional program for acquiring the Carrier-based Suppression of Enemy Air Defenses (SEAD) using Unmanned Combat Aircraft Systems (UCAS) and their enabling

The present dissertation deals with the synthesis and characterization of new metal-rich borides of the Ce{sub 7}Ni{sub 5±x}Ge{sub 3±x}In{sub 6{sup -}}, Nb{sub 2}OsB{sub 2{sup -}} and NbRuB-type.The samples are synthesized by a solid state reaction route from elements using an electric arc furnace. The structural characterization of the compounds was carried out by using X-ray diffraction methods on powder samples and single crystals. The chemical composition of single-crystals was verified by EDX analyses. Moreover, the magnetic properties of suitable samples were investigated by SQUID magnetometry.The crystal structure of compounds with the nominal composition NbFe{sub 1-x}Ir{sub 6+x}B{sub 8} is successfully solved from single crystal X-ray data. The most prominent feature in this structure are one-dimensional chains along the c-axis formed by the magnetically active element iron on a site of mixed occupation with Iridium (Fe: Ir = 0.77 (2) 0.23 (2)). Thermomagnetic investigations reveal, that ferromagnetic ordering is observed below the Curie temperature (TC) of 350 K. Theoretical investigations suggest that the iron-chains are mainly responsible for the ferromagnetic ordering. In addition, the magnetocaloric effect (MCE) is calculated using isothermal magnetization measurements at several temperatures. The maximal magnetic entropy change ΔS = 0.032 J kg{sup -1} K{sup -1} is observed in the vicinity of T{sub C}. For the phases Nb{sub 6}Mn{sub 0,75(2)}Ir{sub 6,25(2)}B{sub 8} and Nb{sub 6}Co{sub 1,09(2)}Ir{sub 5,91(2)}B{sub 8} a relationship between the measured ferrimagnetic ordering and the crystal structure is found. Tiny superstructure reflections measured by Selected Area Electron Diffraction (SEAD) indicate a different crystal system for those compounds, which allows a ferrimagnetic spin arrangement within this crystal structure.In the second part of the thesis new results about the Nb{sub 2}OsB{sub 2-} and NbRuB-type borides are presented, which both

São Paulo from 1901, 1960 and 2000. Mortality data were collected from Annual Statistical Reports of Fundação SEADE (State Data Analysis System Foundation, for 1901; from Annual Statistical Reports of the State Department of Statistics, for 1961; and from a CD-ROM of the Ministry of Health, for 2000. The population data, number of newborns and infant mortality rates were collected from the CD-ROM "500 anos de Divisão Territorial e 100 Anos de Estatísticas Demográficas Municipais" (500 years of Territory Division and 100 Years of Municipal Demographic Statistics of FSEADE. During the 20th century, the population of the City of São Paulo increased 36-fold, the number of newborns 24-fold and deaths 13.6-fold. On the other hand, mortality rates decreased, general mortality was 2.6 times lower and infant mortality was 11.3 lower in 2000 when compared to 1901. The proportion of deaths due to infectious diseases decreased from 45.7% of total deaths in 1901 to 9.7% in 2000. Taking into consideration the 10 main causes of death for 1901, 5 were infectious diseases, corresponding to 37% of all deaths. In 1960 there were only 3 infectious diseases among the main causes of deaths, accounting for 16.1% of all deaths, and in 2000 only pneumonia was among the 10 main causes of death. Tetanus, diphtheria, whooping cough, measles, and scarlet fever were controlled in this period. Nevertheless, infectious diseases as pneumonia, septicemia, tuberculosis, and AIDS still deserve special attention from public health authorities.
