    This annual statistical report aims to propagate the information about the generation, transmission and distribution systems evolution and about the electric power market from the Parana State, Brazil, in 1996. The electric power consumption in the distribution area of the Parana Power Company (COPEL) presented a growth about 6,7%. The electric power production in the the COPEL plants increased 42,2% higher than 1995, due to the outflows verified in the Iguacu river and to the long period of the affluence reduction that the Southern region tanks coursed during this year. This report presents statistical data about the following topics: a) electric power energy balance from the Parana State; b) electric power energy balance from the COPEL - own generation, certain interchange, electric power requirement, direct distribution and the electric system 6 graphs, 3 maps, 61 tabs.; e-mail: splcnmr at mail.copel.br

    Full Text Available The Financial Accounting impedes the registration on behalf of the information on the intangible of the different companies. To attenuate this situation, many companies offer voluntary data on them in the accounting documentation. This work analyzes the voluntary information of the Spanish companies about the intangible, impacting in the place that they occupy inside the Annual Report. The main conclusion of the investigation is that the companies offer the voluntary information that more it interests them for their own motivations and, however, the users of the Financial Accounting need a wider and more comparable information on the Human Capital.La normalización contable actual impide el registro de parte de la información sobre los intangibles de las diferentes empresas. Para atenuar esta situación, muchas empresas ofrecen datos voluntarios sobre ellos en la documentación contable que ofrecen a terceros.

  5. Response from youths and teachers with regard to the encyclopedic database on nuclear power, ATOMICA

    International Nuclear Information System (INIS)

    An encyclopedic database on nuclear power and its related fields, commonly named ATOMICA, was first established and released on a PC communications basis in 1995. The database started to be operated on the internet in October 1996. Now ATOMICA contains more than 2,300 encyclopedic data which include tables and figures over 9,300 in total. The fields the database covers are categorized into 18 areas: energy and environment, nuclear power generation, advanced reactors, fuel cycle, back end technology, safety research, basic and advanced research, radiation application, radiation influence and protection, governmental policy, regulation and rule, statistics of operation of nuclear facilities, international cooperation, etc. The number of access to the database has increased steadily, reaching more than one and a half million a year in 2003. The influence of and protection against radiation are most frequently accessed being followed by energy and environment, nuclear power generation, and nuclear fuel cycle and status of foreign countries. People with different backgrounds are believed to have an access to the database. This paper gives firstly and overview of the activities on the establishment and maintenance of ATOMICA including its historical background. Then accesses to the database are analyzed from the aspects of their number and fields. PA Center has also received questions and comments on the database from various people. In this regard the features of questions and comments are summarized with special reference to those from youths and teachers as well as from general public. This is done to elucidate the requirements to the database from the viewpoint of education. In general youths and teachers are interested in the characteristics of radiation in the nature and from nuclear facilities. They are concerned about the effect of radiation on human bodies. Besides radiation the areas they pay keen attention to are mechanism of fission and principle of nuclear

  6. Evaluation of radioactive wastes in Instituto de Energia Atomica (Sao Paulo-Brazil)

    International Nuclear Information System (INIS)

    An evaluation of present and future production of radioactive waste in several departments of the Instituto de Energia Atomica has been done. Taking into account this evaluation, the criteria for disposal and convenient treatment technique have been studied. The most critical form of liquid radioactive waste is that of 131I processing because high concentration of radiotellurium always accompanies this form of waste. Ion exchange and precipitation techniques were used to study this waste processing. Two kinds of resins were used by the ion exchange method: the strong anionic and the stron cationic. Quantitative tellurium retention has not been attained by the ion exchange method using either resins. The technique of precipitation of radioactive tellurium as ammonium tellurate was also used, allowing us to obtain more than 99% of tellurium removal. The remaining radioactive wastes can be eliminated using the storage for decay criteria with further release to the sewers in the case of liquids and burial in the case of solids. (Author)

  7. Environmental radiometric control at the vicinity of the Instituto de Energia Atomica, Sao Paulo, Brazil

    International Nuclear Information System (INIS)

    Optimized derived limits (ODL) for gaseous and liquid wastes released to the environment of Instituto de Energia Atomica (IEA) following the ICRP's recommendations were determined. Techniques for routine environmental monitoring were implanted in order to ensure that these limits be respected. The treatment of liquid wastes which gives rise to the optimized discharge resulted from cost-benefit analysis, is the elimination of medium half-lived radioisotopes in the soil. The ODL value for iodine-131 is 50mCi/y and 7,5 Ci/y for gaseous and liquid effluents, respectively. The ODL values for other radionuclides of radiosanitary interest in liquid waste also determined. The most appropriate environmental monitoring techniques for IEA were studied and parameters of radioactive material dilution in the atmosphere and water courses were determined. Sample collection points were chosen to obtain the most representative data for the evaluation of radioactive dose in the critical group and the detriment produced in the population. Detection system and methods were calibrated and standardized for the determination of radionuclides in wastes released from IEA in order to evaluate their concentrations in the main transference pathways.

    Full Text Available Apresentam-se resultados de pesquisa utilizando como fonte o banco de dados Relação Anual de Informações Sociais (RAIS, do Ministério do Trabalho e Emprego. O objetivo é verificar informações sobre remuneração de professores de ensino médio nas capitais brasileiras e, ao mesmo tempo, refletir sobre o potencial dessa base de dados para a análise. A opção por um recorte analítico relativo a professores de ensino médio deve-se à constatação de que, para o período compreendido entre 1996 e 2008, os dados sobre tais empregos estavam mais bem informados na RAIS, embora ela apresente certa irregularidade nas informações sobre o setor público. O período histórico selecionado deve-se à hipótese de que a política de fundos vigente entre 1998 e 2006, que priorizou o ensino fundamental, poderia ter efeito negativo na remuneração de professores de ensino médio. Para analisar as médias de remuneração, utilizaram-se o salário mínimo e o Índice de Preços ao Consumidor (IPC como indexadores que permitem comparação do poder aquisitivo no período. Este estudo exploratório parece confirmar uma relação negativa, esperada, entre a priorização do ensino fundamental via políticas de fundos e a remuneração dos professores de ensino médio; além disso, evidencia o afastamento entre a valorização do salário mínimo nacional e a política de valorização do magistério, e, finalmente, expõe fragilidades da RAIS para o trabalho com os dados de remuneração do setor público de forma desagregada. Todavia, a coincidência entre os resultados deste trabalho e de estudos que se debruçaram sobre outras bases de dados indica a pertinência da continuidade das análises.The text presents results of a research using as its source the Annual List of Social Information - Relação Anual de Informações Sociais (RAIS database of the Ministry of Labor and Employment.

  4. Review on quality control techniques of UO2 pellets under pilot-plant conditions, at Instituto de Energia Atomica, Sao Paulo, Brazil

    International Nuclear Information System (INIS)

    The Instituto de Energia Atomica's Metallurgy Division Pilot Plant has been established to develop fabrication and control techniques of ceramic fuel elements, to train personnel and to acquire experience in quality control of fuel pellets. Its close association with the Institute's Chemical Engineering Division, where pilot-plant development on uranium and thorium purification is carried out, affords a direct way to ascertain the influence of salt processing variables on the behaviour of oxides derived from such uranium salts (ammonium diuranate and ammonium uranyl carbonate). The pilot plant, with a capacity of about 5 tons of UO2 pellets per year, has ample flexibility in equipment, installations and procedures for such work, comprising uranium salts calcining, UO2 reduction, UO2pellet fabrication, sintering, inspection, centerless grinding and adequate controls, both on powders and on pellets produced. It comprises several self-contained sub-units, corresponding to each particular operation, arranged in such a way that work can be carried independently and asssuring in each good control of accountablity.Quality control techniques are exerted both on powder and on pellets lines. In the powders line, besides the current routine control tests, special ones have been developed and used, comprising grain size microscopy, electron scanning examination of particle shape and sedimentation tests. These controls allow fabrication of oxide powders (mainly natural uranium up to now) to meet the specifications for the particular programs that have been tackled. In the pellets line, with ample flexibility on fabrication steps, both low- (90 to 93 pct density) and medium-density pellets (93 to 95 pct) are produced. Besides the usal routine controls, special tests on quantitative pore and grain sizes distribution through quantitative optical microscopy, electron scanning microscopy and fractographic tests were developed to evaluate the homogeneity and the geometry of pore

    Full Text Available La variabilidad espacial y temporal del ciclo anual de la clorofila-α en el archipiélago de Juan Fernández se analiza usando ocho anos de datos satelitales de clorofila-α, viento, corrientes y nivel del mar. Este archipiélago está conformado por tres islas: Robinson Crusoe-Santa Clara (RC-SC y Alejandro Selkirk (AS. Las islas RC-SC se encuentran en una región de alta energía cinética y mayores concentraciones de clorofila-α definida como Zona de Transición Costera, en cambio la isla AS se encuentra en una región de baja energía cinética y menores concentraciones de clorofila-α denominada Zona Oceánica. RC-SC posee un incremento de las concentraciones de clorofila-a en el lado suroeste, mientras que AS posee sus mayores concentraciones en el lado oeste, indicando la presencia de procesos forzantes diferentes. En ambas islas el ciclo anual de la clorofila es significativo y comienza a incrementar en abril, alcanzando valores relativamente altos entre junio y noviembre, disminuyendo hacia diciembre, hasta alcanzar un mínimo hacia fines de marzo. Este ciclo anual aparece desacoplado con el viento y acoplado con la energía cinética. Incrementos invernales de clorofila-a aparecen vinculados con remolinos de mesoescala provenientes de la zona continental, mientras que incrementos primaverales se podrían asociar a procesos locales vinculados al "efecto masa de isla". En ambas islas existen incrementos significativos de la clorofila-a en la banda anual y cuasi-bianual, pero sólo en AS se encontró una fluctuación significativa en la banda interanual vinculada con el Nino y la Oscilación del Sur.

La producción anual neta de N. fallax fue de 3 070.1 g PS m2. En el mes de junio la biomasa alcanzó su máximo (958.4 g PS m2 . La contribución de biomasa foliar de N. fallax a la proporción total de biomasa representa el 10%, la de peciolos alcanza el 40% y la contribución de biomasa subterránea equivale en ocasiones a más del 50%. El nivel de fósforo en los sedimentos se encuentra por arriba de la cantidad necesaria para sostener la producción vegetal (= 0.04%. Por los resultados obtenidos en este estudio, se puede señalar que en aquellas zonas ribereñas de la laguna en donde los agricultores han construido bordos, se propicia que durante la época de lluvias la columna de agua cambie bruscamente sus dimensiones pasando de 10 cm hasta alcanzar los 75 cm de profundidad y se eleven los niveles de fósforo en agua y sedimentos, lo que a su vez induce queNymphoides fallaxse vea estresada, y en un caso extremo, temporalmente sea sustituida por aquellas especies mejor adaptadas a las nuevas condiciones físicas y químicas del medio.

    Firstly, the estimates of standard deviation and arithmetic mean as basic statistical parameters are emphasised, which point out the variability and magnitude of annual streamflow records in the hydrological studies of planning water-resource developments inside a region. Then the equations for quantitative evaluations of statistical convenience of extending a short stream flow record are described in detail. The previous makes use of additional and common data in one or two closer hydrometric stations, with this the short observed record has a certain correlation (dependence or association). Later two numerical applications to real problems are given, the first one for the two dimensional model, which uses a closed hydrometric station in order to extend the short record, and the second application for the three dimensional model which makes use of two auxiliary hydrometric stations. Lastly, three general observations about the paper are cited. [Spanish] Inicialmente se destaca la importancia de las estimaciones de la medida y la desviacion estandar como parametros estadisticos basicos, los cuales caracterizan la magnitud y la variabilidad de los volumenes escurridos anuales en los estudios hidrologicos de planeacion del aprovechamiento de los recursos hidraulicos de una region.

    Full Text Available El objetivo del presente estudio fue determinar la variación anual en la composición química y astringencia de la fracción comestible por vacunos del follaje de Enterolobium cyclocarpum. Durante el año 2009, se realizaron seis muestreos (febrero, abril, junio, agosto, octubre y diciembre en un bosque semicaducifolio tropical en Venezuela. En cada muestreo se consideraron 10 plantas diferentes, cada una como repetición en un diseño completamente aleatorizado. Los valores obtenidos para materia orgánica (84.50 ± 1.38%, proteína cruda (17.8 ± 1.83%, extracto etéreo (4.50 ± 1.05%, fibra en detergente neutro (42.90 ± 2.26% y ácido (27.10 ± 3.30% se ubicaron dentro de los valores de referencia para plantas leñosas tropicales. La relación calcio:fósforo varió de 2.6:1 (abril hasta 6.8:1 (octubre. Los fenoles totales (4.50 ± 0.64%, taninos totales (3.40 ± 0.65% y taninos condensados (0.77 ± 0.25%, al igual que las fracciones anteriores, se incrementaron (P<0.05 al final del periodo húmedo, coincidiendo con el inicio de la floración. La astringencia (1.50 a 2.30 g Eat/100 g MS evidenció baja actividad biológica de compuestos que precipitan proteínas. Se concluye que el follaje de E. cyclocarpum puede emplearse como una fuente suplementaria de nutrientes a vacunos en sistemas silvopastoriles en áreas de bosque seco tropical semicaducifolio.

Se propone también un procedimiento para estimar sus parámetros, basado en el método de máxima verosimilitud. El modelo ha funcionado muy bien en la mayoría de las muestras de caudales máximos hasta ahora analizadas, dos de las cuales se incluyen como ejemplos de aplicación para ilustrar el procedimiento. El modelo propuesto ha resultado ser la mejor opción de ajuste a los datos de muestra provenientes de varias poblaciones, cuando ha sido comparado con dos distribuciones de probabilidad de una población y con otro modelo de tres poblaciones.This study examines the three population general extreme value (TPGEV distribution for application in annual flood frequency analysis. We also propose a procedure for estimating its' parameters based on a maximum likelihood method. The model has functioned very well for most of the samples of maximum flows studied to date, two of which are included as illustrative examples in use of the procedure. The proposed model has proved to be the best option for the fitting of data arising from various populations when it has been compared with two probability distributions from one population and another model of three populations.

  11. Design of a costing system and valuation for the production of radiopharmaceutical FDG and the provision of radiology service with PET-CT to Caja Costarricense del Seguro Social, for the Centro de Investigacion en Ciencias Atomicas, Nucleares y Moleculares of the Universidad de Costa Rica

    International Nuclear Information System (INIS)

    The cost of the radiopharmaceutical FDG and of the service of diagnostic studies with PET-CT technology are determined through the design of a costing system. The aim has been to provide to the Centro de Investigacion en Ciencias Atomicas, Nucleares y Moleculares (Cicanum), an appropriate decision making as to definition of sale prices in the CCSS-Cicanum Project. This project has arisen of the partnership between the Cicanum and Caja Costarricense del Seguro Social (CCSS), in order to satisfy the needs in the area of oncology; specifically, the acquisition of PET-CT technology. Diagnostic studies can be performed with this technology to detect and measure the evolution of different types of cancer. Additionally, the realization of these studies have required the acquisition of a cyclotron for the production of the radiopharmaceutical called FDG by Cicanum. The theoretical and conceptual aspects relating to atomic, nuclear and molecular sciences are defined, as well as the contribution of the Universidad de Costa Rica for research in these areas and perspectives of costing systems. The administrative-accounting area of Cicanum is described and diagnosed, as well as of the CCSS-Cicanum Project, to know its scope, management and allocation of costs. The situation diagnosed in the administrative-accounting area of Cicanum and the CCSS-Cicanum Project are analyzed, through the tool Swotr (strengths, opportunities, weaknesses, threats and risks). A costing system is elaborated for Cicanum, based on work orders. The system has been developed in a series of electronic work sheets that have allowed to obtain costs associated with the production of the radiopharmaceutical FDG and the rendering of diagnostic services with PET-CT technology to the CCSS, as well as the definition of sales price. As a complement to the above, a master budget is done, which provides a financial vision of the project in its first ten years of operation

    Full Text Available Por su localización en el ecotono tierra-mar Rhizophora mangle es un organismo con gran sensibilidad al cambio climático. La existencia de anillos anuales climáticamente sensibles en esta especie revela un enorme potencial para la dendroclimatologia tropical. Aunque se ha documentado la existencia de anillos anuales en el género Rhizophora delimitados por cambios en la densidad de poros, aquí se demuestra mediante el uso de la tomografía computarizada que los anillos en R. mangle también están definidos por cambios de densidad de la madera. La comparación entre el número de máximos de densidad de madera (DM y de poros (DP en secciones trasversales con la edad de los árboles, reveló la anualidad de los anillos de crecimiento de R. mangle. A mayor precipitación mayor DP y menor DM; y viceversa. La DM y la DP se interpretan como rasgos adaptativos que le permiten a R. mangle adaptarse a los pulsos anuales en salinidad relacionados con las descargas de los ríos en la bahía de Cispatá.Because of its location in the land-sea ecotone Rhizophora mangle is an organism with great sensitivity to climate change. The existence of climate sensitive annual rings in this specie highlights its potential relevance for tropical dendroclimatology. Even though had been previously established the existence of annual rings, delimited by changes in pore-density, in Rhizophora genus, using computed tomographies, is also possible demonstrate, that the rings in R. mangle can also be defined by changes in wood density. Comparing wood density maxima (DM and pore density maxima (PD in tree cross-sections reveal the annual nature of R. mangle tree-rings. With increased rainfall PD increases and DM decreases, and vice versa. PD and DM are interpreted as adaptive traits that allow R. mangle to adapt to the conditions produced by annual pulses in salinity in the bay of Cispatá related to high and low discharges of the rivers.

    Full Text Available This work aimed to study the annual variation of temperature of the coat surface and other traits of coat in Holstein cows managed in a tropical environment by separately considering black coat and white coat. It was measured the coat thickness (mm characteristic, hair length (mm, hair number (hair/cm² and coat surface temperature on 191 crossbred cows with 7/8 and 31/32 Holstein composition distributed in 3 herds in a semi-arid environment. Less dense coats with shorter, flattened hair occurred predominantly in March, a time coinciding to high levels of solar radiation. This type of coat shows low resistance to the flux of latent and sensitive heat through the skin, thus favoring heat loss. The black coat surface temperature was on average 4ºC higher than that of the white one during all the year and its variation followed that of the mean radiant temperature. The models developed to predict the effective thermal conductivity of the coat must take these differences into account because the thermal gradient parallel to the skin surface is not negligible for Holstein cows under the sun in a tropical environment, as well as the other traits.O objetivo neste trabalho foi estudar a variação anual da temperatura superficial e outras características do pelame de vacas holandesas em ambiente tropical, considerando separadamente as malhas negras e brancas.

    Full Text Available Annual ryegrass is a temperate climate annual foraging grass, grown mostly in the South of Brazil, especially in the state of Rio Grande do Sul. Despite its importance, little is known about its genetic diversity, both within and among the populations cultivated. This knowledge is of fundamental importance for developing breeding and conservation strategies. The aim of this study was to characterize the genetic diversity and structure of four populations of annual ryegrass. Three of the populations were located in Rio Grande do Sul and the fourth in Uruguay. RAPD markers were used to study the genetic diversity and structure of these populations. Analysis of 375 individuals sampled from the populations, using six RAPD primers, generated a total of 82 amplified bands. They included 73 polymorphic bands (89,02%. The value of the total genetic diversity index obtained, (0,71 was high, indicating the presence of wide genetic diversity in the four populations. Genetic structure analysis revealed that 98% of total diversity is intrapopulational, whereas interpopulational genetic diversity was only 2%. These results suggest that before these populations separated, they had gone through a period of gene exchange and, even after the separation event, gene frequency stayed at levels similar to the original levels, with no differential selection for these genes in the different cultivation areas.O azevém anual é a gramínea anual forrageira de clima temperado de maior utilização no sul do Brasil, particularmente no Estado do Rio Grande do Sul.

    Full Text Available La variabilidad espacial y temporal del ciclo anual de la clorofila-α en el archipiélago de Juan Fernández se analiza usando ocho anos de datos satelitales de clorofila-α, viento, corrientes y nivel del mar. Este archipiélago está conformado por tres islas: Robinson Crusoe-Santa Clara (RC-SC y Alejandro Selkirk (AS. Las islas RC-SC se encuentran en una región de alta energía cinética y mayores concentraciones de clorofila-α definida como Zona de Transición Costera, en cambio la isla AS se encuentra en una región de baja energía cinética y menores concentraciones de clorofila-α denominada Zona Oceánica. RC-SC posee un incremento de las concentraciones de clorofila-a en el lado suroeste, mientras que AS posee sus mayores concentraciones en el lado oeste, indicando la presencia de procesos forzantes diferentes. En ambas islas el ciclo anual de la clorofila es significativo y comienza a incrementar en abril, alcanzando valores relativamente altos entre junio y noviembre, disminuyendo hacia diciembre, hasta alcanzar un mínimo hacia fines de marzo. Este ciclo anual aparece desacoplado con el viento y acoplado con la energía cinética. Incrementos invernales de clorofila-a aparecen vinculados con remolinos de mesoescala provenientes de la zona continental, mientras que incrementos primaverales se podrían asociar a procesos locales vinculados al "efecto masa de isla". En ambas islas existen incrementos significativos de la clorofila-a en la banda anual y cuasi-bianual, pero sólo en AS se encontró una fluctuación significativa en la banda interanual vinculada con el Nino y la Oscilación del Sur.The spatial and temporal variability of the annual cycle of chlorophyll-a in the Juan Fernandez archipelago is analyzed through eight years of satellite data of chlorophyll-a, wind, currents and sea level.

O período de coleta de dados através de radiossondagens foi de janeiro de 2002 a dezembro de 2009 no âmbito do projeto South Hemisphere ADditional OZonesondes (SHADOZ. Os índices termodinâmicos não explicam o máximo de precipitação observado em julho, porém apresentam-se em fase com um máximo secundário em abril. Os fluxos de energia estática úmida e saturada mostram que o ciclo anual da precipitação é modulado pelos mecanismos que geram instabilidade termodinâmica associados à convergência de umidade em baixos níveis.The relation between thermodynamic instability indexes, precipitable water content, static energy flux, and rainfall annual cycle over Maxaranguape (coastland site, Rio Grande do Norte, Northeast of Brazil was investigated. The radiosonde dataset covered the period from January 2002 to December 2009 within the South Hemisphere ADditional OZonesondes (SHADOZ project. The thermodynamics indexes variability do not explain the maximum rainfall in July, however they are in phase with the secondary maximum in April. The annual cycle of the moist and saturated static energy fluxes showed that rainfall cycle is modulated by both thermodynamics and low level moisture convergence mechanisms.

    The principal aim of this investigation was to study the anual morpho-histological changes in the ovary of the fish capitan, Eremophilus mutisii, in the Rio Bogota basin in Colombia, with regard to the reproductive cycle, size of the mature fishes and seasonal changes in the environment. The fibs material was collected monthly. The gonads were fixed in Bouin's fixative. Subsequently they were washed several times in 70% ethanol. Transversal sections of about 5 cm in length, each of which produced 10 slides with 10 or so sections per slide, were taken from the center to the anterior portion of the right ovary of each fish, since no macroscopic significant differencie was observed in the oogenic process in the anterior, central and posterior portion of the ovary. The sections were dehydrated in tetrahydrofuran and embedded in paraffin. Sections were cut at 6 microns and stained with haematoxylin and eosin (H & E. The gonosomatic index (GSI or maturity index (MIl was calculated.

    Full Text Available It was evaluated the annual evolution of global, direct and diffuse components of incident solar radiation on tilted surfaces to 12.85, 22.85 and 32.85º, facing north, in Botucatu, state of São Paulo, Brazil. The radiometric fractions were obtained for each component of the radiation in the aforementioned surfaces, through the ratio with the global and top of the atmosphere radiations. Seasonality was evaluated based on monthly averages of daily values. The measures occurred between 04/1998 and 07/2001 at 22.85º; 08/2001 and 02/2003 at 12.85º; and from 03/2003 to 12/2007 at 32.85º, with concomitant measures in the horizontal surface (reference. The levels of global and direct radiation on tilted surfaces were lower in summer and higher in the equinoxes when compared with the horizontal. The diffuse radiation on tilted surfaces was lower in most months, with losses of up to 65%. A trend of increasing differences occurred between horizontal and tilted surfaces with the increase of the angle in all the components and fractions of incident radiation. The annual evolution of rainfall and cloud cover ratio directly affected the atmospheric transmissivity of direct and diffuse components in the region.Avaliou-se a evolução anual das componentes global, direta e difusa da radiação solar incidente em superfícies inclinadas a 12,85; 22,85 e 32,85º, com face voltada ao Norte, em Botucatu-SP. Foram obtidas frações radiométricas para cada componente da radiação nas superfícies supracitadas, através de razões com a radiação global e a do topo da atmosfera. A sazonalidade foi avaliada através das médias mensais dos valores diários.

    Full Text Available The present review examines the main attributes and agronomic characteristics of arrowleaf clover (Trifolium vesiculosum Savi and its incorporation into production systems in dryland areas of the Andean foothills of the humid Mediterranean climate zone of Chile. It is a new species of annual legume in Chile for light and medium textured soils. The root system can reach a depth of 1.5 m and its seeds have a high percentage of hardseedness (99.8%. It is an upright plant, with purplish-white flowers. The mature plant has large arrow-shaped leaves up to 50 mm long, often marked with a large white “V”. Dry matter and seed production in the Andean foothills is high (3.9-8.8 t DM ha-1 and 700-900 kg ha-1, respectively, surpassing the productivity of sub clover (Trifolium subterraneum L. cv. Mount Barker and crimson clover (Trifolium incarnatum L.. However, DM production in the second year was lower, possibly because the high percentage of hardseedness inhibited plant emergence. The phenological records and productive performance suggest that arrowleaf clover could contribute to improving pastoral production in dryland areas with annual rainfall levels of more than 800 mm, such as the Andean foothills in the central-southern region of Chile.En la presente revisión se examinan los principales atributos y características agronómicas del trébol vesiculoso (Trifolium vesiculosum Savi y su eventual incorporación a sistemas de producción en la precordillera andina de la zona de clima mediterráneo húmedo de Chile.

    Full Text Available O objetivo deste trabalho foi avaliar os efeitos da altura de manejo em pastagem de aveia preta e azevém anual sobre o estabelecimento e o rendimento de grãos da cultura de soja. Os tratamentos utilizados foram quatro alturas de manejo do pasto: 10, 20, 30 e 40cm e um tratamento sem pastejo. Foram avaliados atributos referentes à pastagem (altura do pasto, oferta de forragem, massa de forragem, taxa de acúmulo, taxa de lotação animal e palhada residual e à cultura da soja (estande inicial de plantas e rendimento de grãos. As alturas reais do pasto ficaram próximas daquelas pretendidas, havendo um aumento linear da oferta de forragem e da massa de forragem quando foi observado aumento das alturas de manejo do pasto. A taxa de acúmulo não foi afetada pelos tratamentos. A taxa de lotação apresentou resposta linear decrescente com o aumento da altura do pasto. A massa de forragem remanescente aumentou na medida em que houve incremento na altura de manejo do pasto. Foi observada diferença entre os tratamentos para palhada residual e estande inicial de plantas de soja, porém essas diferenças não afetaram o rendimento de grãos da cultura. Os resultados sugerem que a presença dos animais não prejudica o cultivo subsequente, possibilitando aumento da renda do produtor pela oportunidade de utilização das áreas durante a entressafra da soja.This trial aimed to evaluate the effects of sward height management of pastures composed by black oat and Italian ryegrass upon soybean establishment and yield. The treatments were four sward management heights: 10, 20, 30 and 40cm; and no grazing control. Pasture (sward height, herbage allowance, herbage mass, stocking rate and post grazing herbage mass and soybean (initial stand of plants and yield attributes were evaluated. The observed sward heights were very similar to those previously intended. There was a linear increase in herbage allowance and herbage mass with increasing sward height

Os animais utilizados foram ovinos da raça Corriedale, ao final da gestação e início de lactação, que permaneceram no experimento no período de 3 de julho a 18 de novembro de 2000, onde foram realizadas avaliações em três estádios fenológicos: vegetativo (E1, pré-florescimento (E2 e florescimento (E3. Os animais foram mantidos em pastejo contínuo, com lotação variável de forma a manter-se uma oferta de matéria seca (MS em torno de 15% do peso vivo animal (PV. Foram determinados o ganho de PV/ha, o ganho médio diário (GMD e a carga animal. Como resultado das avaliações, observou-se oferta média de MS de folhas verdes de 7,2% do PV sendo que, no final do ciclo, a porcentagem de colmos e material morto foi mais elevada, dificultando a ação seletiva dos animais. Este declínio progressivo na qualidade da pastagem também foi verificado no teor de proteína bruta, que decresceu de 23,7% no E1 para 19,4% no E3 e da digestibilidade in vitro da matéria orgânica, que decresceu de 80,55% no E1 para 60,70% no E3. Em resposta a esta condição da pastagem, observaram-se adequados GMD, tanto para as ovelhas (103 g e 87 g como para os cordeiros (289 g e 279 g nos estádios vegetativo e pré-florescimento. Por outro lado, no estádio de florescimento, os ganhos diários decresceram para ovelhas (-112 g e cordeiros (89 g. Estes resultados evidenciaram o alto potencial do azevém anual em termos de ganho de PV nos estádios vegetativo (225 kg/ha e pré-florescimento (145 kg/ha. Todavia, a redução da qualidade da forragem no estádio de florescimento inviabiliza sua utilização para a produção de animais de alta exigência.The study was carried out in an experimental area of 5.41 ha, split in four paddocks of similar size.

As alturas de manejo foram avaliadas em delineamento de blocos completos casualisados com três repetições. Procedeu-se a três avaliações diurnas, por observação visual direta: duas avaliações de acordo com o estádio vegetativo e a terceira com o estádio reprodutivo. A redução da altura de manejo do pasto esteve relacionada a maior carga animal e resultou em menor massa de forragem e massa de lâminas foliares. Nessa condição de limitação, os animais aumentaram a taxa de bocados, o número de bocado por estação alimentar, o número total de bocados, o número de estação alimentar visitada e reduziram o tempo de permanência na estação alimentar. Esse padrão de resposta resultou em menor deslocamento entre estações alimentares, no entanto, a quantidade de deslocamento total foi maior. Os animais modificam seus padrões de deslocamento e captura de forragem em resposta à altura de manejo do pasto. A limitação de forragem pode ter impacto no sistema de integração lavoura-pecuária.This experiment was aimed to evaluate the grazing strategies of steers in Italian ryegrass (Lolium multiflorum Lam. and black oat (Avena strigosa Schreb. pastures managed with four sward heights, 10, 20, 30 and 40 cm.

Foram observados tempos de pastejo diário de 9,65; 10,97 e 10,68 h, taxas de bocados de 52,65; 51,93 e 40,63 bocados/min e pesos de bocados de 0,064; 0,055 e 0,048 g/bocado, que resultaram em taxas de consumo de forragem de 4,48; 3,91 e 2,72% do peso vivo/dia, nos estádios vegetativo, pré-florescimento e florescimento, respectivamente. Estas evoluções foram acompanhadas por diminuições das relações folha:caule da forragem disponível (3,6:1; 1,44:1 e 0,56:1, evidenciando a limitação qualitativa da forragem no estádio de florescimento. Estes dados demonstraram que, até o estádio de pré-florescimento, as estratégias desenvolvidas pelos animais permitiram adequado consumo de forragem, enquanto, no estádio de florescimento, a baixa qualidade da pastagem determinou queda no consumo, considerado insuficiente para atender as necessidades nutricionais de ovelhas lactantes com seus respectivos cordeiros.This work was carried out at the field to evaluate the grazing sheep behavior conducted in annual ryegrass (Lolium multiflorum Lam. on vegetative, pre-flowering and flowering stages.

    This dissertation introduces the concept of Information Integrity, which is the detection and possible correction of information manipulation by any intermediary node in a communication system. As networks continue to grow in complexity, information theoretic security has failed to keep pace. As a result many parties whom want to communicate,…

  20. Information Forests

    CERN Document Server

    Yi, Zhao; Dewan, Maneesh; Zhan, Yiqiang

    2012-01-01

    We describe Information Forests, an approach to classification that generalizes Random Forests by replacing the splitting criterion of non-leaf nodes from a discriminative one -- based on the entropy of the label distribution -- to a generative one -- based on maximizing the information divergence between the class-conditional distributions in the resulting partitions. The basic idea consists of deferring classification until a measure of "classification confidence" is sufficiently high, and instead breaking down the data so as to maximize this measure. In an alternative interpretation, Information Forests attempt to partition the data into subsets that are "as informative as possible" for the purpose of the task, which is to classify the data. Classification confidence, or informative content of the subsets, is quantified by the Information Divergence. Our approach relates to active learning, semi-supervised learning, mixed generative/discriminative learning.

    Despite large deregulation efforts, informal economic activity still represents a large share of GDP in many developing countries. In this paper we look at incentives to reduce informal activity when capitalists in the formal sector regulate entry. We consider a dual economy with a formal sector employing educated workers and an informal sector with unskilled workers. We show that high costs of education make labor migration and profits in the formal sector an increasing function of its size....

  3. Towards a strategic line of intellectual capital development for CNEA (Comision Nacional de Energia Atomica de Argentina)

    International Nuclear Information System (INIS)

    After an extended stagnation period, during which there was a big staff reduction in the nuclear sector in general and in CNEA in particular, with no new personnel hired, ageing staff and risk of skills and knowledge loss, in 2006 the Argentinean government launched a nuclear power programme based on the necessity of expanding the national energy matrix and taking into account the general concerns about greenhouse effects. The new projects drove to CNEA to the elaboration of a ten year Strategic Plan for CNEA, which includes the activities to be performed during the period 2009-2018. Conceived with wide participation of internal areas, the definition of the strategic plan included objectives, goals, management indicators, and periodical revisions. The Intellectual Capital being a fundamental asset to reach the goals, a chapter on these subject was included, for every knowledge domain. Even if the work is still in progress, partial results and tendencies can be shown. Every area of the organization is working on the analysis of their own strengths and weaknesses in terms of intellectual capital, knowledge loss risk analysis, and definition of future needs in terms of knowledge and skills. Analyzing strengths and weaknesses, there appeared common elements to most of the areas, indicating that besides the use of specific knowledge management, education and training tools, a Strategic Line for Intellectual Capital Development should be quickly implemented, to fill in gaps and protect the current knowledge asset. This presentation summarizes the work done up to now, showing tendencies in the situation, and proposing a strategic line for intellectual capital development, to help solving major staffing problems in CNEA.

  4. Installation and development of neutron radiography in the nuclear reactor (IEAR-1) of the Instituto de Energia Atomica, Brazil

    International Nuclear Information System (INIS)

    Investigations on the field of Neutron Radiography have been performed at the IEAR-1, swimming pool reactor utilizing a collimated neutron beam and the so-called photographic transfer method as a mean of detection. The test object (sample) is placed between the neutron source (reactor core) and the gold foil. The acitivity of its different points is the inverse measure of the neutrons absorbed in the test sample at the corresponding points. The activity distribution on the gold foil is determined again by exposing it to an X-ray film. A multichannel type collimator consisting of an assemblage of stainless steel tubes inside an aluminium mantle (tube) was used as a direction beam selector. Improvements have been introduced in respect to the reduction of angular divergence and neutron scattering. To improve further the quality of the radiographs another collimator type has been developed using boric acid as a neutron absorber and moderator. Flux measurements by means of gold foil activation at reactor positions of interest were necessary to eliminate errors originating of different neutron flux values. The dependence of film darkening upon the neutron flux and other factors have been discussed. Finally neutron-and gama-radiographs of the same objects were evaluated in comparison. (author)

  5. CNEA's (Comision Nacional de Energia Atomica) experience in the preparation of a national system for laboratory accreditation

    International Nuclear Information System (INIS)

    Within the regional markets, as it is the case of MERCOSUR , the laboratories which are suppliers of test and calibration results, are mutually recognized through the National Accreditation Systems. In Argentina there is a project to create a Center for the Accreditation of Test Laboratories. CNEA, which is involved in the execution of large projects and has adopted quality assurance criteria for a long time, requires for internal and external laboratories to be qualified. At the beginning of this year, a Committee for the Qualification of Laboratories was created in the Research and Development and Fuel Cycle Areas. Its objective was planning, management of documents, coordination, evaluation and quantification of laboratories, according to national IRAM and international ISO standards. This paper analyzes the organization of the system and the methods to evaluate and qualify laboratories as a process of growing up leading to the future National Accreditation System.

  11. Information barriers

    International Nuclear Information System (INIS)

    An information barrier (IB) consists of procedures and technology that prevent the release of sensitive information during a joint inspection of a sensitive nuclear item, and provides confidence that the measurement system into which it has been integrated functions exactly as designed and constructed. Work in the U.S. on radiation detection system information barriers dates back at least to 1990, even though the term is more recent. In January 1999, an Information Barrier Working Group (IBWG) was formed in the United States to help coordinate technical efforts related to information barrier research and development (R and D). This paper presents an overview of the efforts of this group, by its present and former Chairs, as well as recommendations for further information barrier R and D. Progress on the demonstration of monitoring systems containing IBs is also provided. From the U.S. IBWG perspective, the top-level functional requirements for the information barrier portion of an integrated radiation signature-information barrier inspection system are twofold: The host must be assured that its classified information is protected from disclosure to the inspecting party; and The inspecting party must be confident that the integrated inspection system measures, processes, and presents the radiation-signature-based measurement conclusion in an accurate and reproducible manner. It is the position in the United States that in the absence of any agreement to share classified nuclear weapons design information while implementing an inspection regime, the need to protect host country classified warhead design information is paramount and overrules the need to provide confidence to the inspecting party regarding the accuracy and reproducibility of the measurements. The U.S. IBWG has reached a consensus on several critical design elements that define a general standard for radiation signature information barrier design. Technical specialists from cooperating parties must be

    During the reception of a piece of information, we are never passive. Depending on its origin and content, from our personal beliefs and convictions, we bestow upon this piece of information, spontaneously or after reflection, a certain amount of confidence. Too much confidence shows a degree of naivety, whereas an absolute lack of it condemns us as being paranoid. These two attitudes are symmetrically detrimental, not only to the proper perception of this information but also to its use. Beyond these two extremes, each person generally adopts an intermediate position when faced with the recep

    In most developing countries, it is the private, informal markets that the rural poor have traditionally turned to service their financial needs. Why have these institutions succeeded in providing services to the poor when formal institutions have not? Do these informal institutions provide any lessons that bigger formal institutions could use? What are their basic limitations? Answers to such questions indicate important direc-tions for public policy.

    This paper analyzes the problem of matching heterogeneous agents in a Bayesian learning model. One agent gives a noisy signal to another agent, who is responsible for learning. If production has a strong informational component, a phase of cross-matching occurs, so that agents of low knowledge catch up with those of higher one. It is shown that: (i) a greater informational component in production makes cross-matching more likely; (ii) as the new technology is mastered, pr...

    Goedel Incompleteness Theorem leaves open a way around it, vaguely perceived for a long time but not clearly identified. (Thus, Goedel believed informal arguments can answer any math question.) Closing this loophole does not seem obvious and involves Kolmogorov complexity. (This is unrelated to, well studied before, complexity quantifications of the usual Goedel effects.) I consider extensions U of the universal partial recursive predicate (or, say, Peano Arithmetic). I prove that any U eithe...

  5. Information management - Assessing the demand for information

    Rogers, William H.

    1991-01-01

    Information demand is defined in terms of both information content (what information) and form (when, how, and where it is needed). Providing the information richness required for flight crews to be informed without overwhelming their information processing capabilities will require a great deal of automated intelligence. It is seen that the essence of this intelligence is comprehending and capturing the demand for information.

    Full Text Available The area of image processing has made rapid strides because of enormous applications it has in different fields. This growth can also be attributed to the increasing use of fuzzy logic in all tasks of image processing as the fuzzy logic facilitates the representation of inherent uncertainty in the image information which can be local or global. For problems like enhancement global information is of interest whereas the local information is needed for the problems of edge detection, segmentation, and recognition. However we need both for the noise removal. The images are of varied types: Medical images (CT scans, MR, X-rays, ECG, etc., satellite images, natural scenes, videos, games, multimedia, biometrics, industrial, astronomical so on and so forth. The approaches to tackle different images have to be different. For example skin texture can’t represented by a colour model.Defence Science Journal, 2011, 61(5, pp.405-407, DOI:http://dx.doi.org/10.14429/dsj.61.1192

    Biological weapons are within reach of individuals, small groups, terrorist organizations, as well as nations. With pervasive integration of civilian and military populations worldwide, the ill winds of biological warfare stand to affect military troops and civilians alike. A variety of technologies are emerging - such as pathogen detection devices, streaming internet characterization tools, information exploitation techniques, automated feature extraction, and ubiquitous wireless communication - that can help. These technologies, if taken together within an integrated analytical framework, could make possible the monitoring of diverse parameters that may indicate a change in the state of health of a given population - either the emergence of a naturally occurring disease or the outbreak of a disease as a result of hostile intent. This presentation will discuss the application of new information surveillance tools and technologies as they apply to health and disease monitoring, particularly within the context of potential terrorist or hostile nation use of biological warfare. Although discussed within the specific context of health surveillance, the tools and processes described here are generally applicable within other domains of subject matter expertise.

  10. Quantum information

    International Nuclear Information System (INIS)

    There is more to information than a string of ones and zeroes the ability of ''quantum bits'' to be in two states at the same time could revolutionize information technology. In the mid-1930s two influential but seemingly unrelated papers were published. In 1935 Einstein, Podolsky and Rosen proposed the famous EPR paradox that has come to symbolize the mysteries of quantum mechanics. Two years later, Alan Turing introduced the universal Turing machine in an enigmatically titled paper, On computable numbers, and laid the foundations of the computer industry one of the biggest industries in the world today. Although quantum physics is essential to understand the operation of transistors and other solid-state devices in computers, computation itself has remained a resolutely classical process. Indeed it seems only natural that computation and quantum theory should be kept as far apart as possible surely the uncertainty associated with quantum theory is anathema to the reliability expected from computers? Wrong. In 1985 David Deutsch introduced the universal quantum computer and showed that quantum theory can actually allow computers to do more rather than less. The ability of particles to be in a superposition of more than one quantum state naturally introduces a form of parallelism that can, in principle, perform some traditional computing tasks faster than is possible with classical computers. Moreover, quantum computers are capable of other tasks that are not conceivable with their classical counterparts. Similar breakthroughs in cryptography and communication followed. (author)

    A Systems Analysis Group has existed at Sandia National Laboratories since at least the mid-1950s. Much of the groups work output (reports, briefing documents, and other materials) has been retained, along with large numbers of related documents. Over time the collection has grown to hundreds of thousands of unstructured documents in many formats contained in one or more of several different shared drives or SharePoint sites, with perhaps five percent of the collection still existing in print format. This presents a challenge. How can the group effectively find, manage, and build on information contained somewhere within such a large set of unstructured documents? In response, a project was initiated to identify tools that would be able to meet this challenge. This report documents the results found and recommendations made as of August 2013.

  14. Information Security

    International Nuclear Information System (INIS)

    As nuclear materials and technologies spread, the global community needs to be ever more vigilant to prevent their acquisition by those that have no legitimate reason to access or use them. International efforts to strengthen nuclear security measures gained momentum when, in 2009, President Obama announced his intention to convene for the first time an international Nuclear Security Summit. Held in Washington in 2010, the Summit was attended by 47 Heads of State who collectively committed to securing all vulnerable nuclear material within four years. Two years later, 53 Heads of State came together at a second Summit in Seoul and agreed a set of concrete actions to deliver on this ambition. The Summit process has functioned not only as a catalyst to move nuclear security up States’ political consciousness, but also as a platform for broadening their perspective on this agenda. Specifically, the last three years have seen the international community increasingly recognise the fundamental need for nuclear security regimes to protect not only nuclear material and physical assets from non-state actors, but also the information needed to obtain and use these goods for nefarious purposes

    Information has two aspects. One aspect is the objective one; another aspect is the subjective one. Shannon has discussed the objective aspect of information in information theory. But the subjective aspect of information has not been fully discussed. Someone use "Bayesian approaches" to evaluate the value of information. But in some cases it does not meet the information user's need. This paper is focus on the subjective aspect of objectively measurable information and gives formal definitions for information, information utility, and marginal information utility, normalized calculation of information utility. The information discussed in the paper has interdisciplinary nature. This work can be the foundation of many application areas.

    Full Text Available The work of managers in small and medium-sized enterprises is very information-intensive and the environment in which it is done is very information rich. But are managers able to exploit the wealth of information which surrounds them? And how can information be managed in organisations so that its potential for improving business performance and enhancing the competitiveness of these enterprises can be realised? Answers to these questions lie in clarifying the context of the practice of information management by exploring aspects of organisations and managerial work and in exploring the nature of information at the level of the organisation and the individual manager. From these answers it is possible to suggest some guidelines for managing the integration of business strategy and information, the adoption of a broadly-based definition of information and the development of information capabilities.

    Full Text Available The paper brings an overview of information visualization field, concentrating on its application to information retrieval systems. It presents the basis of information visualization and the reasons that implicate the use of visualization in information retrieval systems. It also discusses the selection of the right visualization technique and portrays some examples of visualization. Special attention is given to evaluation problems and results of information retrieval visualizations that were made so far. Even though studies have not proved information retrieval to be more successful with the use of visualization, it seems that researchers still believe in the power and the advantages of visualization and continue to look for a technique that would prove that. The authors conclude that with the changes on the web and the progress made in information retrieval systems, the time for visualization that would live up to its expectations might only be coming.

    DEFF Research Database (Denmark)

    Hertzum, Morten

    2008-01-01

    Since common ground is pivotal to collaboration, this paper proposes to define collaborative information seeking as the combined activity of information seeking and collaborative grounding. While information-seeking activities are necessary for collaborating actors to acquire new information, the...... activities involved in information seeking are often performed by varying subgroups of actors. Consequently, collaborative grounding is necessary to share information among collaborating actors and, thereby, establish and maintain the common ground necessary for their collaborative work. By focusing on the...... collaborative level, collaborative information seeking aims to avoid both individual reductionism and group reductionism, while at the same time recognizing that only some information and understanding need be shared....

    Energy Technology Data Exchange (ETDEWEB)

    Ferreira Junior, Evaristo Santiago

    1986-03-15

    This paper analyzes the causes and scope of the nuclear energy diffusion process in the capitalist world. It also aims at explaining Brazil's role in this process. The study contemplates two main concepts that are, here, considered to be driving and directing vectors: the World Capital and the Capitalist State. According to the expanded reproduction logic, World Capital forms the world nuclear productive subsystem, which commands and directs, in this process, hundreds (or thousands) of productive units, regardless of their geographical location, nationality or capital control. Thru the utilization of available public intervention tools, the Capitalist state has favored the formation of the world nuclear productive subsystem, thus guiding the accumulation process in the interior of this system. Therefore, the conclusion of the Nuclear Cooperation Agreement between Brazil and Germany and the resultant establishment of the Brazilian Nuclear Program (following the authoritarian model of public administration), is well fitted in the general dynamics of subordination/articulation of the Brazilian economy to the world economy and, particularly, to the world nuclear productive subsystem.

  4. Digital Information and Value

    Directory of Open Access Journals (Sweden)

    Paul Walton

    2015-11-01

    Full Text Available Digital information changes the ways in which people and organisations interact. This paper examines the nature of this change in the context of the author’s Model for Information (MfI. It investigates the relationship between outcomes and value, selection processes and some attributes of information and explores how this relationship changes in the move from analogue to digital information. Selection processes shape the evolution of information ecosystems in which conventions are established for the ways in which information is used. The conventions determine norms for information friction and information quality as well as the sources of information and channels used. Digital information reduces information friction, often dramatically, and changes information quality. The increasing use of analytics in business increasingly delivers predictive or prescriptive digital information. These changes are happening faster than information ecosystem conventions can change. The relationships established in the paper enable an analysis of, and guide changes to, these conventions enabling a more effective use of digital information.

    How do genetic systems gain information by evolutionary processes? Answering this question precisely requires a robust, quantitative measure of information. Fortunately, 50 years ago Claude Shannon defined information as a decrease in the uncertainty of a receiver. For molecular systems, uncertainty is closely related to entropy and hence has clear connections to the Second Law of Thermodynamics. These aspects of information theory have allowed the development of a straightforward and practical method of measuring information in genetic control systems. Here this method is used to observe information gain in the binding sites for an artificial 'protein' in a computer simulation of evolution. The simulation begins with zero information and, as in naturally occurring genetic systems, the information measured in the fully evolved binding sites is close to that needed to locate the sites in the genome. The transition is rapid, demonstrating that information gain can occur by punctuated equilibrium. PMID:10908337

    Full Text Available Problem statement. Modern information technology is developing in a globalized economy, the formation of a common information space and as a result, changes relation to the information of participants of market relations. New conditions lead to an increase in the number of parties involved in the creation and use of information, to the increase of the volume of information and the frequency of its use, making the actual task of the operational management of the activity of the staff of the various organizations. Information support includes normative and reference data; the necessary classificatory of technical and economic information; arrays of data needed to solve problems; standardized documents. The main purpose of providing information is timely to give management system, accurate information in particular, decision-makers, necessary and sufficient for making optimal or near-management decisions. Purpose of the article: to study and to improve methods of the design of information support (IS and of implemented solutions for the objects, the arrangement and forms of organization of the information circulating in the automated control system when it is functioning as an object of a certain structure. Conclusion. Thus, the choice of a method of designing information support determines by the necessity of the development of the mathematical apparatus, providing the formal means of work with information resources. The mathematical apparatus and methods should provide the formulated tasks of designing information support.

    Full Text Available Evolutionary information theory is a constructive approach that studies information in the context of evolutionary processes, which are ubiquitous in nature and society. In this paper, we develop foundations of evolutionary information theory, building several measures of evolutionary information and obtaining their properties. These measures are based on mathematical models of evolutionary computations, machines and automata. To measure evolutionary information in an invariant form, we construct and study universal evolutionary machines and automata, which form the base for evolutionary information theory. The first class of measures introduced and studied in this paper is evolutionary information size of symbolic objects relative to classes of automata or machines. In particular, it is proved that there is an invariant and optimal evolutionary information size relative to different classes of evolutionary machines. As a rule, different classes of algorithms or automata determine different information size for the same object. The more powerful classes of algorithms or automata decrease the information size of an object in comparison with the information size of an object relative to weaker4 classes of algorithms or machines. The second class of measures for evolutionary information in symbolic objects is studied by introduction of the quantity of evolutionary information about symbolic objects relative to a class of automata or machines. To give an example of applications, we briefly describe a possibility of modeling physical evolution with evolutionary machines to demonstrate applicability of evolutionary information theory to all material processes. At the end of the paper, directions for future research are suggested.

    International Nuclear Information System (INIS)

    In recent years, risk informed activities are being investigated as scientifically rational measures. Some Risk informed activities using Core Damage Frequency (CDF) have been already employed. Examples are extraction of accident management strategies, risk informed maintenance importance and such. This paper describes risk information such as CDF, risk profile, risk importance of equipments' contribution to risk, gained from Probabilistic Analysis (PSA). Furthermore, risk informed activities conducted and/or considered are also introduced. The examples are investigation of accident management strategies, on-line maintenance and risk informed In Service Inspection (ISI). In the end, open issues for further employment of risk information in the NPP activities are summarized. Technical quality of PSA methodology is one of these issues and it should be continuously addressed, however, the risk information as it is still useful for better activities in NPP. (author)

For molecular systems, uncertainty is closely related to entropy and hence has clear connections to the Second Law of Thermodynamics. These aspects of information theory have allowed the development of a straightforward and practic...

  11. Dynamic statistical information theory

    Institute of Scientific and Technical Information of China (English)

    XING; Xiusan

    2006-01-01

    In recent years we extended Shannon static statistical information theory to dynamic processes and established a Shannon dynamic statistical information theory, whose core is the evolution law of dynamic entropy and dynamic information. We also proposed a corresponding Boltzmman dynamic statistical information theory. Based on the fact that the state variable evolution equation of respective dynamic systems, i.e. Fokker-Planck equation and Liouville diffusion equation can be regarded as their information symbol evolution equation, we derived the nonlinear evolution equations of Shannon dynamic entropy density and dynamic information density and the nonlinear evolution equations of Boltzmann dynamic entropy density and dynamic information density, that describe respectively the evolution law of dynamic entropy and dynamic information. The evolution equations of these two kinds of dynamic entropies and dynamic informations show in unison that the time rate of change of dynamic entropy densities is caused by their drift, diffusion and production in state variable space inside the systems and coordinate space in the transmission processes; and that the time rate of change of dynamic information densities originates from their drift, diffusion and dissipation in state variable space inside the systems and coordinate space in the transmission processes. Entropy and information have been combined with the state and its law of motion of the systems. Furthermore we presented the formulas of two kinds of entropy production rates and information dissipation rates, the expressions of two kinds of drift information flows and diffusion information flows. We proved that two kinds of information dissipation rates (or the decrease rates of the total information) were equal to their corresponding entropy production rates (or the increase rates of the total entropy) in the same dynamic system. We obtained the formulas of two kinds of dynamic mutual informations and dynamic channel

    1997-01-01

    Is symmetry informative? The answer is both yes and no. We examine what information and symmetry are and how they are related. Our approach is primarily mathematical, not because mathematics provides the final word, but because it provides an insightful and relatively precise starting point. Information theory treats transformations that messages undergo from source to destination. Symmetries are information that leave some property of interest unchanged. In this respect the studies of information and symmetry can both be regarded as a Quest for the identity transformation. PMID:9224554

  18. Nuclear Information Democratization

    International Nuclear Information System (INIS)

    Nuclear information (Nl) interests people for many reasons, with energy supply, safety, and security being at the top of the list. Democratizing nuclear information has its roots in the growth of a knowledge-based economy, the knowledge worker as a user of nuclear information, developments in information and communication technologies (ICT), and the impact of internet growth. Results of democratization are apparent in the process of information creation, in how nuclear information is distributed and accessed, and in the conditions for using the information found. The International Nuclear Information System (INIS) both reflects and contributes to these trends. Nuclear information falls under the overall umbrella of scientific and technical information (STI). It is highly specialized, but it follows general principles and trends of STI. The world of STI has its own culture and its own long-established rules of use and existence. These have brought us many inventions and improvements, introduced important technological changes, and made our lives and work much easier and more pleasurable. However, the world is constantly changing, and the traditional closed STI environment, including the world of nuclear information, is not keeping up with today’s changes. (author)

    2007-01-01

    We review of the interface between (theoretical) physics and information for non-experts. The origin of information as related to the notion of entropy is described, first in the context of thermodynamics then in the context of statistical mechanics. A close examination of the foundations of statistical mechanics and the need to reconcile the probabilistic and deterministic views of the world leads us to a discussion of chaotic dynamics, where information plays a crucial role in quantifying predictability. We then discuss a variety of fundamental issues that emerge in defining information and how one must exercise care in discussing concepts such as order, disorder, and incomplete knowledge. We also discuss an alternative form of entropy and its possible relevance for nonequilibrium thermodynamics. In the final part of the paper we discuss how quantum mechanics gives rise to the very different concept of quantum information. Entirely new possibilities for information storage and computation are possible due t...

  4. What constitutes information integrity?

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available This research focused on what constitutes information integrity as this is a problem facing companies today. Moreover, information integrity is a pillar of information security and is required in order to have a sound security management programme. However, it is acknowledged that 100% information integrity is not currently achievable due to various limitations and therefore the auditing concept of reasonable assurance is adopted. This is in line with the concept that 100% information security is not achievable and the notion that adequate security is the goal, using appropriate countermeasures. The main contribution of this article is to illustrate the importance of and provide a macro view of what constitutes information integrity. The findings are in harmony with Samuel Johnson's words (1751: 'Integrity without knowledge is weak and useless, and knowledge without integrity is dangerous and dreadful.'

  5. Accident management information needs

    International Nuclear Information System (INIS)

    The tables contained in this Appendix A describe the information needs for a pressurized water reactor (PWR) with a large, dry containment. To identify these information needs, the branch points in the safety objective trees were examined to decide what information is necessary to (a) determine the status of the safety functions in the plant, i.e., whether the safety functions are being adequately maintained within predetermined limits, (b) identify plant behavior (mechanisms) or precursors to this behavior which indicate that a challenge to plant safety is occurring or is imminent, and (c) select strategies that will prevent or mitigate this plant behavior and monitor the implementation and effectiveness of these strategies. The information needs for the challenges to the safety functions are not examined since the summation of the information needs for all mechanisms associated with a challenge comprise the information needs for the challenge itself

  6. Information barriers and authentication

    International Nuclear Information System (INIS)

    Acceptance of nuclear materials into a monitoring regime is complicated if the materials are in classified shapes or have classified composition. An attribute measurement system with an information barrier can be emplo,yed to generate an unclassified display from classified measurements. This information barrier must meet two criteria: (1) classified information cannot be released to the monitoring party, and (2) the monitoring party must be convinced that the unclassified output accurately represents the classified input. Criterion 1 is critical to the host country to protect the classified information. Criterion 2 is critical to the monitoring party and is often termed the 'authentication problem.' Thus, the necessity for authentication of a measurement system with an information barrier stems directly from the description of a useful information barrier. Authentication issues must be continually addressed during the entire development lifecycle of the measurement system as opposed to being applied only after the system is built.

  7. Metric adjusted skew information

    DEFF Research Database (Denmark)

    Hansen, Frank

    2008-01-01

    We extend the concept of Wigner-Yanase-Dyson skew information to something we call "metric adjusted skew information" (of a state with respect to a conserved observable). This "skew information" is intended to be a non-negative quantity bounded by the variance (of an observable in a state) that...... vanishes for observables commuting with the state. We show that the skew information is a convex function on the manifold of states. It also satisfies other requirements, proposed by Wigner and Yanase, for an effective measure-of-information content of a state relative to a conserved observable. We...... establish a connection between the geometrical formulation of quantum statistics as proposed by Chentsov and Morozova and measures of quantum information as introduced by Wigner and Yanase and extended in this article. We show that the set of normalized Morozova-Chentsov functions describing the possible...

    Quantitative information flow aims to assess and control the leakage of sensitive information by computer systems. A key insight in this area is that no single leakage measure is appropriate in all operational scenarios; as a result, many leakage measures have been proposed, with many different properties. To clarify this complex situation, this paper studies information leakage axiomatically, showing important dependencies among different axioms. It also establishes a completeness result abo...

    How much information can a transmitted physical system fundamentally communicate? We introduce the principle of quantum information causality, which states the maximum amount of quantum information that a quantum system can communicate as a function of its dimension, independently of any previously shared quantum physical resources. We present a new quantum information task, whose success probability is upper bounded by the new principle, and show that an optimal strategy to perform it combines the quantum teleportation and superdense coding protocols with a task that has classical inputs.

  18. Safeguards information management system

    International Nuclear Information System (INIS)

    The requirements for the management of information at the IAEA and its Department of Safeguards are rapidly changing. Historically, the Department of Safeguards has had the requirement to process large volumes of conventional safeguards information. An information management system is currently in place that adequately handles the IAEA's conventional safeguards data needs. In the post-Iraq environment, however, there is a growing need to expand the IAEA information management capability to include unconventional forms of information. These data include environmental sampling results, photographs, video film, lists of machine tools, and open-source materials such as unclassified publications. The United States Department of Energy (DOE) has responded to this information management need by implementing the safeguards information management system (SIMS) initiative. SIMS was created by the DOE to anticipate and respond to IAEA information management needs through a multilaboratory initiative that will utilize an integrated approach to develop and deploy technology in a timely and cost effective manner. The DOE will use the SIMS initiative to co-ordinate US information management activities that support the IAEA Department of Safeguards. (author). 1 ref., 2 figs

    Information is a precise concept that can be defined mathematically, but its relationship to what we call "knowledge" is not always made clear. Furthermore, the concepts "entropy" and "information", while deeply related, are distinct and must be used with care, something that is not always achieved in the literature. In this elementary introduction, the concepts of entropy and information are laid out one by one, explained intuitively, but defined rigorously. I argue that a proper understanding of information in terms of prediction is key to a number of disciplines beyond engineering, such as physics and biology.

    2004-01-01

    I flew to Washington last week, a trip rich in distributed information management. Buying tickets, at the gate, in flight, landing and at the baggage claim, myriad messages about my reservation, the weather, our flight plans, gates, bags and so forth flew among a variety of travel agency, airline and Federal Aviation Administration (FAA) computers and personnel. By and large, each kind of information ran on a particular application, often specialized to own data formats and communications network. I went to Washington to attend an FAA meeting on System-Wide Information Management (SWIM) for the National Airspace System (NAS) (http://www.nasarchitecture.faa.gov/Tutorials/NAS101.cfm). NAS (and its information infrastructure, SWIM) is an attempt to bring greater regularity, efficiency and uniformity to the collection of stovepipe applications now used to manage air traffic. Current systems hold information about flight plans, flight trajectories, weather, air turbulence, current and forecast weather, radar summaries, hazardous condition warnings, airport and airspace capacity constraints, temporary flight restrictions, and so forth. Information moving among these stovepipe systems is usually mediated by people (for example, air traffic controllers) or single-purpose applications. People, whose intelligence is critical for difficult tasks and unusual circumstances, are not as efficient as computers for tasks that can be automated. Better information sharing can lead to higher system capacity, more efficient utilization and safer operations. Better information sharing through greater automation is possible though not necessarily easy.

  18. Public information strategies

    International Nuclear Information System (INIS)

    The Chernobyl accident in 1986 uncovered serious information problems in many Western countries, and started a debate on crisis communication and information strategies in relation to radiation danger in society. The information problem focuses on four main perspectives. The first is related to information as a persuasion process in which an efficient strategy would influence both the public's knowledge of radiation danger, their attitude towards it and their behaviour. The second perspective calls attention to the importance of the different elements of the information process. How important are different characteristics of the information source; the message itself, and the receiver? The third perspective concentrates on different types of information. What is this issue all about, why is the situation as it is, and how should people behave to protect themselves? The fourth perspective points to the various phases of a crisis. The information needed is obviously not the same in the period before a crisis emerges when no one knows what is going to happen, in the warning period when one knows that something may happen, and during the crisis itself.

    I will briefly explain the definition and advantage of hybrid quantum information processing, which is hybridization of qubit and continuous-variable technologies. The final goal would be realization of universal gate sets both for qubit and continuous-variable quantum information processing with the hybrid technologies. For that purpose, qubit teleportation with a continuousvariable teleporter is one of the most important ingredients.

    We show that quantum information can be encoded into entangled states of multiple indistinguishable particles in such a way that any inertial observer can prepare, manipulate, or measure the encoded state independent of their Lorentz reference frame. Such relativistically invariant quantum information is free of the difficulties associated with encoding into spin or other degrees of freedom in a relativistic context.

    Full Text Available Modern medicine is facing a complex environment, not from medical technology but rather government regulations and information vulnerability. HIPPA is the government’s attempt to protect patient’s information yet this only addresses traditional record handling. The main threat is from the evolving security issues. Many medical offices and facilities have multiple areas of information security concerns. Physical security is often weak, office personnel are not always aware of security needs and application security and transmission protocols are not consistently maintained. Health insurance needs and general financial opportunity has created an emerging market in medical identity theft. Medical offices have the perfect storm of information collection, personal, credit, banking, health, and insurance. Thieves have realized that medical facilities have as much economic value as banks and the security is much easier to crack. Mostly committed by insiders, medical identity theft is a well-hidden information crime. In spite of its covert nature, the catastrophic ramification to the victims is overt. This information crime involves stealing patients’ records to impersonate the patients in an effort of obtaining health care services or claiming Medicare on the patients’ behalf. Unlike financial identity theft, there is a lack of recourse for the victims to recover from damages. Medical identity theft undermines the quality of health care information systems and enervates the information security of electronic patient record.

    Full Text Available The rapid development of information technology has influenced informatics as an important role in business development and management. Manifestations of computerization in the current economy mostly reflect the application of information systems for planning and strategic different analysis, especially when making long-term decisions. These systems consist of several information systems and management control systems for decision support. The construction of these systems was originally a requirement for the strategic planning of top managers (the highest level of leadership having as a primary goal the easier access to important information, especially those that were classified as critical for success in business. Expert systems for example offered the possibility of linking information technology with other telecommunication channels which makes them possible to identify many problems. In this context, this paper will focus on presenting the great importance of information technology as a powerful tool to manage business problems precisely because information systems provide exceptional business value. Information Technology examines the reasons for the problems and offers solutions to manage and reduce them.

  8. Fundamentals of quantum information

    International Nuclear Information System (INIS)

    The fact that information is physical means that the laws of quantum mechanics can be used to process and transmit it in ways that are not possible with existing systems. Ever since its invention in the 1920s, quantum physics has given rise to countless discussions about its meaning and about how to interpret the theory correctly. These discussions focus on issues like the Einstein-Podolsky-Rosen paradox, quantum non-locality and the role of measurement in quantum physics. In recent years, however, research into the very foundations of quantum mechanics has also led to a new field quantum information technology. The use of quantum physics could revolutionize the way we communicate and process information. The important new observation is that information is not independent of the physical laws used to store and processes it (see Landauer in further reading). Although modern computers rely on quantum mechanics to operate, the information itself is still encoded classically. A new approach is to treat information as a quantum concept and to ask what new insights can be gained by encoding this information in individual quantum systems. In other words, what happens when both the transmission and processing of information are governed by quantum laws? (UK)

  13. What is information?

    Science.gov (United States)

    Barbieri, Marcello

    2016-03-13

    Molecular biology is based on two great discoveries: the first is that genes carry hereditary information in the form of linear sequences of nucleotides; the second is that in protein synthesis a sequence of nucleotides is translated into a sequence of amino acids, a process that amounts to a transfer of information from genes to proteins. These discoveries have shown that the information of genes and proteins is the specific linear order of their sequences. This is a clear definition of information and there is no doubt that it reflects an experimental reality. What is not clear, however, is the ontological status of information, and the result is that today we have two conflicting paradigms in biology. One is the 'chemical paradigm', the idea that 'life is chemistry', or, more precisely, that 'life is an extremely complex form of chemistry'. The other is the 'information paradigm', the view that chemistry is not enough, that 'life is chemistry plus information'. This implies that there is an ontological difference between information and chemistry, a difference which is often expressed by saying that information-based processes like heredity and natural selection simply do not exist in the world of chemistry. Against this conclusion, the supporters of the chemical paradigm have argued that the concept of information is only a linguistic metaphor, a word that summarizes the result of countless underlying chemical reactions. The supporters of the information paradigm insist that information is a real and fundamental component of the living world, but have not been able to prove this point. As a result, the chemical view has not been abandoned and the two paradigms both coexist today. Here, it is shown that a solution to the ontological problem of information does exist. It comes from the idea that life is artefact-making, that genes and proteins are molecular artefacts manufactured by molecular machines and that artefacts necessarily require sequences and coding

    International Nuclear Information System (INIS)

    This study was undertaken in order to plan an information strategy for possible future accidents involving radioactivity. Six health visitors and six farmers working in the districts of Norway which received the largest amounts of fallout from the Chernobyl accident, were interviewed. The questions were intended to give an indication of their knowledge about radioactivity and radiation, as well as their needs for information in case of a future accident. The results indicate a relatively low educational background in radiation physics and risk estimation. On the other hand the two groups showed a remarkable skill and interest in doing their own evaluation on the background of information that was linked to their daily life. It is suggested that planning of information in this field is done in close cooperation with the potential users of the information

    The economics of information covers a wide range of topics such as insurance, stochastic equilibria, the theory of finance (e.g. option pricing), job search, etc. In this paper, we focus on an economic model in which traders are uncertain about the true characteristics of commodities and know only the probability distributions of those characteristics. The traders acquire information on those characteristics via the actual consumption in the past and are allowed to exchange the information among themselves prior to the forthcoming trade. Though optimal consumption at the preceding trade generally alters optimal consumption at the succeeding trade, it may happen that they both coincide. We call this particular type of optimal consumption an information stable equilibrium (ISE). At an ISE, the traders gain no additional information from consumption, which is significant enough to revise their optimal choice at the succeeding trade. .

  2. Controlling Quantum Information

    CERN Document Server

    Landahl, A J

    2002-01-01

    Quantum information science explores ways in which quantum physical laws can be harnessed to control the acquisition, transmission, protection, and processing of information. This field has seen explosive growth in the past several years from progress on both theoretical and experimental fronts. Essential to this endeavor are methods for controlling quantum information. In this thesis, I present three new approaches for controlling quantum information. First, I present a new protocol for continuously protecting unknown quantum states from noise. This protocol combines and expands ideas from the theories of quantum error correction and quantum feedback control. The result can outperform either approach by itself. I generalize this protocol to all known quantum stabilizer codes, and study its application to the three-qubit repetition code in detail via Monte Carlo simulations. Next, I present several new protocols for controlling quantum information that are fault-tolerant. These protocols require only local qu...

    The Information Systems Analysis and Development (ISAD) Team of the Safeguards Systems Group at Los Alamos National Laboratory (LANL) has been developing web based information and knowledge management systems for sixteen years. Our vision is to rapidly and cost effectively provide knowledge management solutions in the form of interactive information systems that help customers organize, archive, post and retrieve nonproliferation and safeguards knowledge and information vital to their success. The team has developed several comprehensive information systems that assist users in the betterment and growth of their organizations and programs. Through our information systems, users are able to streamline operations, increase productivity, and share and access information from diverse geographic locations. The ISAD team is also producing interactive visual models. Interactive visual models provide many benefits to customers beyond the scope of traditional full-scale modeling. We have the ability to simulate a vision that a customer may propose, without the time constraints of traditional engineering modeling tools. Our interactive visual models can be used to access specialized training areas, controlled areas, and highly radioactive areas, as well as review site-specific training for complex facilities, and asset management. Like the information systems that the ISAD team develops, these models can be shared and accessed from any location with access to the internet. The purpose of this paper is to elaborate on the capabilities of information systems and interactive visual models as well as consider the possibility of combining the two capabilities to provide the next generation of infonnation systems. The collection, processing, and integration of data in new ways can contribute to the security of the nation by providing indicators and information for timely action to decrease the traditional and new nuclear threats. Modeling and simulation tied to comprehensive

    Full Text Available Modern medicine is facing a complex environment, not from medical technology but rather governmentregulations and information vulnerability. HIPPA is the government’s attempt to protect patient’sinformation yet this only addresses traditional record handling. The main threat is from the evolvingsecurity issues. Many medical offices and facilities have multiple areas of information security concerns.Physical security is often weak, office personnel are not always aware of security needs and applicationsecurity and transmission protocols are not consistently maintained.Health insurance needs and general financial opportunity has created an emerging market in medicalidentity theft. Medical offices have the perfect storm of information collection, personal, credit, banking,health, and insurance. Thieves have realized that medical facilities have as much economic value asbanks and the security is much easier to crack. Mostly committed by insiders, medical identity theft is awell-hidden information crime. In spite of its covert nature, the catastrophic ramification to the victims isovert. This information crime involves stealing patients’ records to impersonate the patients in an effort ofobtaining health care services or claiming Medicare on the patients’ behalf. Unlike financial identity theft,there is a lack of recourse for the victims to recover from damages. Medical identity theft undermines thequality of health care information systems and enervates the information security of electronic patientrecord.

    Late in the 1980's the information system of Japanese corporation has been operated strategically to strengthen its competitive position in markets rather than to make corporate management efficient. Therefore, information-oriented policy in the corporation is making remarkable progress. This policy expands the intelligence activity in the corporation and also leads to the extension of the market in an information industry. In this environment closed corporate system is transformed into open one. For this system network and database are important managerial resources.

    International Nuclear Information System (INIS)

    Full text: Overall, the aim of this paper is to provide the background and the broader vision in which the various information related presentations and posters proposed by the Department find their place, exploring solutions to the challenges faced. At a time when the Agency is expected to be a reference for the assessment of nuclear proliferation threats, providing the international community with independent, impartial, timely and credible conclusions that no declared nuclear material is diverted to non-peaceful purposes and that no undeclared nuclear material or activities exist in States, it has to address major challenges with regard to information. Drawing credible conclusions assumes that all relevant information is accessible and put into relevant context. Because of the legal constraints under which it operates, the limitation of resources for collecting existing but difficult to reach details and simply because of the overwhelming quantity of the information needed to properly evaluate proliferation issues, the Agency has to continually improve the way it collects, processes and internally disseminates safeguards relevant information. Developing a coherent picture of a State's nuclear capability is a complex process based on many experts' assessments and fusion of information. The search for better, broader and deeper information through dedicated collection processes is an ongoing effort aimed at filling the gaps of such pictures. Implementing well selected information collection tools is a sine qua non to render effective the Agency's detection capabilities. Beyond collection, another prerequisite to ensuring that the available information is accessible to those who need to know is the establishment of a proper information system architecture and an efficient set of standard business processes. At the same time, that information must be sufficiently protected by appropriate security measures, particularly at a time when private hacking has become a

    CERN Document Server

    Lee, Jae-Weon

    2010-01-01

    This is an ongoing review on my conjecture that information processing at causal horizons is the key ingredient of all physics. Assuming that information is fundamental and the information propagates with finite velocity, one can find that main physical laws such as Newton's second law and Einstein equation simply describe the energy-information relation (dE=TdS) for matter or space time crossing a causal horizon with temperature T for observers. Quantum mechanics arises from ignorance of the observers about matter crossing the horizon, which explains why superluminal communication is impossible even with quantum entanglement. This approach also explains the origin of Jacobson's thermodynamic formalism of Einstein gravity and Verlinde's entropic gravity. When applied to a cosmic causal horizon, the conjecture reproduces the observed dark energy and demands the zero cosmological constant.

  11. Labor Informality: General Causes

    Directory of Open Access Journals (Sweden)

    Gustavo Sandoval Betancour

    2016-04-01

    Full Text Available The article examines the main causes of labor informality in order to verify the validity of classical theories that explain unemployment in market economies and its relationship to informality. Methodologically, the project was based, in the empirical part, on international statistics, comparing the evolution of labor market structure in a combined sample of highly industrialized countries and other less industrialized ones. Empirical evidence supports the conclusion that the classical economic theory of Marxist origin is inefficient to explain the causes of unemployment in contemporary market economies, as well as it fails to satisfactorily explain informality. On the contrary, we conclude that the theory in question is more relevant to explain informality in centrally planned economies where this phenomenon has been present even more significantly than in free market economies.

  15. Quantifying Information Leak Vulnerabilities

    CERN Document Server

    Heusser, Jonathan

    2010-01-01

    Leakage of confidential information represents a serious security risk. Despite a number of novel, theoretical advances, it has been unclear if and how quantitative approaches to measuring leakage of confidential information could be applied to substantial, real-world programs. This is mostly due to the high complexity of computing precise leakage quantities. In this paper, we introduce a technique which makes it possible to decide if a program conforms to a quantitative policy which scales to large state-spaces with the help of bounded model checking. Our technique is applied to a number of officially reported information leak vulnerabilities in the Linux Kernel. Additionally, we also analysed authentication routines in the Secure Remote Password suite and of a Internet Message Support Protocol implementation. Our technique shows when there is unacceptable leakage; the same technique is also used to verify, for the first time, that the applied software patches indeed plug the information leaks. This is the f...

    The book "Entropy and Information" deals with the thermodynamical concept of entropy and its relationship to information theory. It is successful in explaining the universality of the term "Entropy" not only as a physical phenomenon, but reveals its existence also in other domains. E.g., Volkenstein discusses the "meaning" of entropy in a biological context and shows how entropy is related to artistic activities. Written by the renowned Russian bio-physicist Mikhail V. Volkenstein, this book on "Entropy and Information" surely serves as a timely introduction to understand entropy from a thermodynamic perspective and is definitely an inspiring and thought-provoking book that should be read by every physicist, information-theorist, biologist, and even artist.

    2016-01-01

    A message of any sort can be regarded as a source of information. Claude. E. Shannon showed in the last century that information ("what we don't already know") is equivalent to the entropy as defined in statistical mechanics. A string of experimental observations is like a succession of words; they both convey information and can be characterized by their entropy. For the fluid flow measurements and simulations to be discussed here (pipe and soap film flow, GOY model), the entropy depends on controllable parameters such as the Reynolds number. The information theory approach is applicable to measurements of any type including those governed by intractable equations or systems where the governing equations are not known. This contribution is dedicated to the memory of Leo Kadanoff, an inspiring teacher and one of the most important scientific leaders of the last half century.

    2009-01-01

    One of the most important goals of information management (IM) is supporting the knowledge workers in performing their works. In this paper we examine issues of relevance, linkage and provenance of information, as accessed and used by the knowledge workers. These are usually not adequately addressed in most of the IT based solutions for IM. Here we propose a non-conventional approach for building information systems for supporting the knowledge workers which addresses these issues. The approach leads to the ideas of building Information Warehouses (IW) and Knowledge work Support Systems (KwSS). Such systems can open up potential for building innovative applications of significant impact, including those capable of helping organizations in implementing processes for double-loop learning.

  17. PREFACE: Quantum information processing

    Science.gov (United States)

    Briggs, Andrew; Ferry, David; Stoneham, Marshall

    2006-05-01

    Microelectronics and the classical information technologies transformed the physics of semiconductors. Photonics has given optical materials a new direction. Quantum information technologies, we believe, will have immense impact on condensed matter physics. The novel systems of quantum information processing need to be designed and made. Their behaviours must be manipulated in ways that are intrinsically quantal and generally nanoscale. Both in this special issue and in previous issues (see e.g., Spiller T P and Munro W J 2006 J. Phys.: Condens. Matter 18 V1-10) we see the emergence of new ideas that link the fundamentals of science to the pragmatism of market-led industry. We hope these papers will be followed by many others on quantum information processing in the Journal of Physics: Condensed Matter.
