The dynamics of risk premiums in Nord Pool's futures market

International Nuclear Information System (INIS)

Mork, E.

2006-01-01

Premiums in futures prices are usually considered through the use of 2 models: a no-arbitrage model; and the equilibrium approach or theory of normal backwardation. The no-arbitrage approach equates futures prices with spot prices, storage costs and convenience yields, and is difficult to apply to electricity markets. This paper investigated future electricity prices in Nord Pool's futures market using an equilibrium approach, which split futures prices into an expected spot price component and a risk premium component. Three main hypotheses were used: (1) that risk premiums were present in the Nord Pool futures market during the period 1997-2004; that risk premiums in the Nord Pool futures market were smaller or absent during the period of 2000 to 2002; and, that there was a significant change in risk premiums in Nord Pool's futures market after the winter of 2002-2003 due to a change in consumer hedging behaviour. Futures prices were compared to realized spot prices in their delivery periods in order to test the hypotheses. In order to estimate the futures premiums, a 1-sample test was performed on the entire period for 1, 30, 60, and 90 days before delivery of the block or month contract. The test employed the null hypothesis that the futures premiums were 0. Premiums were positive and varied between 3.7 per cent and 9.3 per cent. The purpose of the study was to determine whether risk premiums were present. Results showed that risk premiums varied over time. Two additional hypotheses were then investigated to examine whether the presence of outside speculators reduced risk premiums, and to see if a period of high prices and volatility caused more buyers to hedge in the futures market. Results showed that in the face of volatility and higher prices, consumers do not purchase fixed-price contracts which would ultimately increase futures premiums in the market. It was concluded that premiums are an important element in the pricing of Nord Pool futures and forwards

Full Text Available Quando pensamos em tradução e enfocamos em aspectos como "por que traduzir?" "quem será meu leitor?" "como abordar os aspectos das culturas?", certamente nos vem o nome da pesquisadora alemã Christiane Nord. No meio acadêmico dos Estudos da Tradução, dos últimos trinta anos, é provável que seu nome se faça presente como teórica importante nos cursos de tradução, na abordagem prática da formação de tradutores, enriquecendo discussões, formando perfis profissionais. Seu trabalho como teórica, professora e tradutora já trouxe um material bastante rico para pensar sobre os Estudos da Tradução e a Tarefa do Tradutor. Ela traz o funcionalismo alemão como uma teoria de tradução aplicável tanto no exercício profissional do tradutor, como na análise comparativa entre texto-fonte e texto-alvo em uma abordagem comunicativa eficiente e real. Nesta entrevista que Nord gentilmente proporcionou, recebendo-me em sua residência em Heidelberg, conversamos sobre algumas questões que aparecem em discussões com colegas que também usam a teoria funcionalista alemã para suas pesquisas e pensam em tradução enquanto teoria e prática. Nord, como lecionando uma de suas aulas, esclarece dúvidas sobre o uso da teoria na prática, sobre os primeiros passos do aprendiz em tradução até se tornar um profissional e sobre questões reais que circundam o mercado da tradução. Ela também traz algumas estratégias e técnicas que o tradutor pode adotar, dependendo do cliente e do leitor, sugerindo possíveis modos de relacionamento entre eles para que o trabalho seja satisfatório para todas as partes, defendendo o conceito de lealdade de sua teoria.

Nord Stream 2 is the name of a project of a pipeline which will transport Russian natural gas into the European Union. The author first presents the context of this project announced during a forum in Saint Petersburg, and signed in september 2015 between Gazprom and several European stakeholders (Eon, BASF, Engie, Shell and OMV). The objective is for Moscow to secure its north-western European market on the long term. Some physical characteristics of the project are evoked, and the European dependence on gas imports is described. The author then discusses how European countries are divided about this project: some support it (like mainly Germany) while some others are fiercely against (Eastern European countries which complain about their loss of transfer revenues, or countries like Bulgaria, Greece and Italy about the loss of an alternative gas corridor). The project also faces legal obstacles related to patrimony separation and access of third parties to the network. Finally, and while mentioning other projects (Nord Stream 1 and South Stream), the author shows that the difficulties and problems faced by this project are a perfect illustration of a fractured European gas sector

NordREG report on the price peaks in the Nordic wholesale market during winter 2009-2010. Final report

Energy Technology Data Exchange (ETDEWEB)

2011-01-15

In winter 2009-2010, prices peaked on three days. The high prices that were experienced in the majority of the Nord Pool Spot price areas initiated a study on the reasons that led to the price spikes and on the possible measures to develop the Nordic market arrangements to avoid such situations in the future. The analysis of the winter 2009-2010 events revealed that there were a number of primary causes for the occurrence of the price peaks and no single individual cause could be pinpointed to bear the key responsibility. The fact that the weather was cold all over the Nordic area in conjunction with the low availability for the Swedish nuclear generation capacity, however, could be indicated as the key underlying causes. The analysis also showed that the way the Nordic transmission capacity is allocated can be listed as an additional factor complementing to the occurrence of the price peaks. Thus, NordREG concluded that a review of the methods of calculating and allocating transmission capacity for the market should be carried out. As a part of this, an analysis that addresses the delimitation of bidding areas and maintenance planning of the transmission network infrastructure should be prepared as well. The flexibility on the demand side has not been very large in the Nordic region. However, the background study prepared by Gaia Consulting showed that even small degree of increased price elasticity could substantially cut the price peaks. This could be seen as an improvement potential of the trading system reflecting the present inability of the market participants to react on the price signals the market place provides. Therefore, NordREG sees that facilitating the appearance of a real price elastic behaviour of the users of electricity can be regarded as one of the key fixes for the problem. Furthermore, NordREG proposes that a consultancy study on how to promote demand flexibility in the Nordic market in a coherent way should be prepared. A further area for

Forecasting Nord Pool day-ahead prices with an autoregressive model

Kristiansen, Tarjei

2012-01-01

This paper presents a model to forecast Nord Pool hourly day-ahead prices. The model is based on but reduced in terms of estimation parameters (from 24 sets to 1) and modified to include Nordic demand and Danish wind power as exogenous variables. We model prices across all hours in the analysis period rather than across each single hour of 24 hours. By applying three model variants on Nord Pool data, we achieve a weekly mean absolute percentage error (WMAE) of around 6–7% and an hourly mean absolute percentage error (MAPE) ranging from 8% to 11%. Out of sample results yields a WMAE and an hourly MAPE of around 5%. The models enable analysts and traders to forecast hourly day-ahead prices accurately. Moreover, the models are relatively straightforward and user-friendly to implement. They can be set up in any trading organization. - Highlights: ► Forecasting Nord Pool day-ahead prices with an autoregressive model. ► The model is based on but with the set of parameters reduced from 24 to 1. ► The model includes Nordic demand and Danish wind power as exogenous variables. ► Hourly mean absolute percentage error ranges from 8% to 11%. ► Out of sample results yields a WMAE and an hourly MAPE of around 5%.

Included were individuals with a GORD diagnosis recorded in any of the nationwide patient registries in the Nordic countries (Denmark, Finland, Iceland, Norway and Sweden) in 1964-2014 (with various start and end years in different countries). Data regarding cancer, other diseases and mortality were retrieved from the nationwide registries for cancer, patients and causes of death, respectively. The NordASCo includes 945 153 individuals with a diagnosis of GORD. Of these, 48 433 (5.1%) have undergone primary antireflux surgery. Median age at primary antireflux surgery ranged from 47 to 52 years in the different countries. The coding practices of GORD seem to have differed between the Nordic countries. The NordASCo will initially be used to analyse the risk of developing known or potential GORD-related cancers, that is, tumours of the oesophagus, stomach, larynx, pharynx and lung, and to evaluate the mortality in the short-term and long-term perspectives. Additionally, the cohort will be used to evaluate the risk of non-malignant respiratory conditions that might be caused by aspiration of gastric contents. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Tip loss correction is known to play an important role for engineering prediction of wind turbine performance. There are two different types of tip loss corrections: tip corrections on momentum theory and tip corrections on airfoil data. In this paper, we study the latter using detailed CFD...... computations for wind turbines with sharp tip. Using the technique of determination of angle of attack and the CFD results for a NordTank 500 kW rotor, airfoil data are extracted and a new tip loss function on airfoil data is derived. To validate, BEM computations with the new tip loss function are carried out...... and compared with CFD results for the NordTank 500 kW turbine and the NREL 5 MW turbine. Comparisons show that BEM with the new tip loss function can predict correctly the loading near the blade tip....

Full Text Available Cet article porte sur l’action culturelle transfrontalière dans l’eurorégion Nord-Transmanche. Cette organisation de coopération territoriale a associé, de 1991 à 2004, la région française du Nord-Pas-de-Calais au Comté anglais du Kent et aux trois régions belges : Région wallonne, Région flamande et Région de Bruxelles-Capitale. La dimension pionnière et historique de cette eurorégion, mais également le fait qu’elle n’a pas perduré, permettent d’illustrer à la fois les potentialités, limites et paradoxes de la mobilisation de la culture dans le contexte des organisations de coopération territoriale. Si le processus d’institutionnalisation de l’eurorégion en tant que telle est resté inachevé, l’espace Nord-Transmanche reste un espace de coopération dynamique, en particulier dans le domaine culturel et la référence eurorégionale reste significative pour de nombreux acteurs. Cet exemple interroge ainsi les enjeux et la réalité de la construction d’une Europe des territoires et de la culture, notamment par rapport aux discours institutionnels dont ces questions font généralement l’objet.

Environnement alimentaire de la vente au détail et expériences de magasinage dans les collectivités des Premières nations du nord des provinces

Directory of Open Access Journals (Sweden)

Kristin Burnett

2017-01-01

Full Text Available Introduction : Cet article porte sur l'environnement de la vente d’aliments dans les collectivités des Premières nations du nord des provinces, en particulier sur la concurrence éventuelle dans la vente au détail de la North West Company (NWC ainsi que sur les expériences d'achats alimentaires de la population vivant dans le Nord canadien. Méthodologie : Nous avons utilisé deux méthodologies pour évaluer l’environnement alimentaire de la vente au détail dans le Nord. D’abord, nous avons cartographié les détaillants en alimentation du Nord afin d’examiner le degré de concurrence au détail dans les régions nordiques, en prêtant une attention particulière aux collectivités qui ne sont pas accessibles à l’année par la route. Ensuite, nous avons enquêté auprès des personnes vivant dans les collectivités du Nord canadien à propos de leurs expériences d’achat au détail et de magasinage. Résultats : Cinquante‑quatre pour cent des collectivités du nord des provinces et du Grand Nord n’avaient aucune épicerie en concurrence avec la NWC. Les provinces comptant les plus fortes proportions de collectivités nordiques sans concurrence dans la vente au détail étaient l’Ontario (87 %, la Saskatchewan (83 % et le Manitoba (72 %. Les participants au sondage (n = 92 ont fait état de leurs préoccupations quant à leurs expériences d'achat dans trois grands secteurs : le coût des aliments, la qualité et la fraîcheur des aliments et la disponibilité de certains aliments. Conclusion : La concurrence dans la vente au détail est limitée dans le nord des provinces. Au Manitoba, en Saskatchewan et en Ontario, la NWC ne fait face à aucune concurrence dans au moins 70 % des collectivités nordiques. Les consommateurs du Nord canadien considèrent que les aliments nutritifs sont peu abordables, et ils souhaitent avoir accès à un plus grand choix d’aliments périssables en bon état.

NORD STREAM 2 and its Soft Power – an Unfolding Playground for the European Union

Directory of Open Access Journals (Sweden)

Roxana Ioana Banciu

2016-06-01

Full Text Available This paper focuses on the Nord Stream 2 pipeline in a double reflection (Russia - the candle, Germany - the mirror handling one particular aspect that influences Russia-EU relations since the Ukrainian factor emerged as a playground for both East and West tectonic plates - namely the energy sector. It is vital for any global power to understand this approach in order to reach people’s minds, in order to emerge as leaders on the world map and to build a strong perception over a political scene. A recently debated subject is Nord Stream 2. The reason why I have chosen to explore this subject is because I am very interested in how Kremlin seeks to have an exclusive control over Eastern Europe, given the full debate in the last three years. In this thesis I will also discuss some important elements of the Russian Soft Power over Europe introducing the plot of South Stream project.

2014-06-01

Many studies have assessed the prevalence of insomnia, but the influence of non-participants has largely been ignored. The objective of the present study was to estimate the prevalence and associated factors of insomnia in a large adult population using DSM-V (diagnostic and statistical manual of mental disorders, 5th ed.) criteria, also taking non-participants into account. This cross-sectional study used data from a questionnaire in The Nord-Trøndelag Health Study (HUNT 3) performed in 2006-2008, and a subsequent non-participant study. The total adult population (n=93,860 aged > or =20 years) of Nord-Trøndelag County, Norway, was invited. Of these, 40,535 responded to the insomnia questionnaire. Among 42,024 eligible non-participants, 6918 (17%) responded to two insomnia questions. Insomnia was diagnosed by applying modified DSM-V criteria. The age-adjusted insomnia prevalence was estimated using the age distribution of all adult inhabitants of Nord-Trøndelag. Supplementary prevalence data were estimated by extrapolating data from the non-participant study. Additionally, the association between insomnia and self-reported health was estimated, adjusting for known confounders. The total age-adjusted prevalence of insomnia was 7.1% (95% confidence interval [CI], 6.9-7.4) (8.6% for women, 5.5% for men). Adjusting for non-participants, the prevalence estimate changed to 7.9% (95% CI, 7.3-8.6) (9.4% for women, 6.4% for men). Insomnia was more than eight times more likely (OR, 8.3; 95% CI, 6.2-11.1) among individuals with very poor versus very good self-reported health, adjusting for age, gender, employment status, chronic musculoskeletal complaints, anxiety and depression. The adjusted insomnia prevalence estimate in Nord-Trøndelag was 7.9%. Insomnia was strongly associated with poor self-reported health. Copyright © 2014 Elsevier B.V. All rights reserved.

Nonlocal relativistic diffusion (NoRD) model of cosmic ray propagation

International Nuclear Information System (INIS)

Uchaikin, V V; Sibatov, R T

2017-01-01

The problem of physical interpretation of the nonlocal relativistic diffusion (NoRD model) for cosmic ray transport in the Galaxy is discussed. The model accounts for the turbulent character of the interstellar medium and the relativistic principle of the speed limitation. Involving fractional calculus and non-Gaussian Lévy statistics yields numerical results compatible with observation data. A special attention is paid to the knee problem. The relativistic speed limit requirement steepens theoretical background spectrum at certain energies, and the position of the break, its sharpness and slopes of asymptotes depend on D α ( E ) and α .

Living better in Nord-Pas de Calais region. For an energy turn and societal transformations - Full report, Synthesis

International Nuclear Information System (INIS)

2015-12-01

In 2008, the NGO Virage-energie Nord-Pas de Calais published a scenario of nuclear power phaseout including objectives of reduction of green gas emissions in the region of Nord-Pas de Calais. In 2013, Virage-energie Nord-Pas de Calais published Scenarios on energy sufficiency and societal transformations: the results of a research project on the evaluation of energy savings potentials from public policies and lifestyle changes. Using data models and assumptions, this study has highlighted that energy sufficiency could generate energy savings from 26 % to 40 %. Global scenarios presented in this report, realised with the financial support of ADEME and regional council of the region Nord-Pas de Calais in partnership with two academic laboratories (TVES, University of Lille 1 - Science and Technologies; and Ceraps, University of Lille 2 - Health and Law), complete previous works with a global vision for the future energetic and social systems. Scenarios explore interactions between energy, lifestyles, agriculture, food habits, consumer goods, industry, buildings, transport and employment, in order to identify and to reduce human, social, economic and environmental vulnerabilities to energetic crisis. Energy sufficiency and resilience are at the heart of this research. Energy sufficiency is a voluntary and organized strategy to reduce energy consumption through lifestyles changes and societal transformations. Energy sufficiency is different from energy efficiency, which concerns only improvement of technical performances in order to reduce energy consumption of a system (building, vehicle, etc.). Sufficiency re-evaluates uses and needs of energy, but also imaginary and culture of a society and its individual and collective organisations. Resilience is the capacity for a system (territory, population, etc.) to absorb a perturbation, to reorganize itself and to continue to remain in a functionally similar state. Through three possible scenarios for the territory and the

4 years of successful knowledge transfer - the nuclear technology training center of the TUeV Nord Group

International Nuclear Information System (INIS)

Willenbockel, I.; Tietze, U.

2007-01-01

In connection with the 2002 amendment to the German Atomic Energy Act, the topics of generational change and maintenance of competence grew in importance and necessitated new solution approaches. To this end, various activities were launched, with the aim of conducting conceptual analyses of these topics. Examples include the 'National Competence Network for Nuclear Technology' (Nationaler Kompetenzverbund fuer Kerntechnik), various networks established by colleges and universities, the 'Knowledge Management for the Maintenance and Transfer of Competence in Reactor Safety' (Wissensmanagement zum Kompetenzerhalt und -transfer in der Reaktorsicherheit) workshop held in 2001 in Garching near Munich (Germany) and the 'Ad-hoc Workgroup on the Maintenance of Competence' (Ad-hoc-Arbeitskreis Kompetenzerhalt) of the VdTUeV. The nuclear technology departments of the TUeV Nord Group were aware of te challenges associated with the generational change early on. By establishing the 'Nuclear Technology Training Center' (Ausbildungszentrum fuer Kerntechnik, AfK), the TUeV Nord Group intended to ensure the required knowledge transfer during the generational change as well as maintain the renowned high qualification as regards the subject of nuclear technology and thus continue to provide - in the sense of social responsibility - crucial contribution to the long-term safety of nuclear plants. Four years have passed since the training center held the first courses in the fall of 2002. Up to now, more than 350 participants have been trained in the courses conducted by the AfK. In the opinion of the TUeV Nord Group, the activities of the AfK have laid the foundation for a successful change of generations within the group's nuclear technology organizations. (orig.)

Full Text Available La chute du mur de Berlin et l’effondrement des régimes communistes eurent pour effet de discréditer et affaiblir de nombreux mouvements révolutionnaires, et de provoquer l’émergence ou la résurgence de mouvements nationalistes.En 1989-90, deux conflits violents faisaient rage au cœur de l’Europe occidentale démocratique, en Irlande du Nord et au Pays Basque.Dans ces deux territoires, des nationalistes, dont certains étaient des radicaux animés par des revendications nationalistes et révolutionnaires s’opposèrent à des états démocratiques par l’utilisation de la violence. Un processus de paix se développa à partir de 1998 en Irlande du Nord ; celui du Pays Basque est toujours dans l’impasse.Il semble au premier abord que ces conflits continuèrent sans bouleversement majeur dans la période qui suivit la chute du mur.Cet article examine les revendications des nationalistes en Irlande du Nord et au Pays Basque pour tenter de dévoiler dans quelle mesure ils furent affectés par ce choc historique.Une perspective comparative permet de comprendre que ces mouvements furent influencés différemment en fonction des contextes locaux. Certains acteurs politiques restèrent volontairement imperméables, alors que d’autres furent davantage affectés par le débat idéologique.

Nord stream: not just a pipeline. An analysis of the political debates in the Baltic Sea region regarding the planned gas pipeline from Russia to Germany

Energy Technology Data Exchange (ETDEWEB)

Whist, Bendik Solum

2008-11-15

This report is an analysis of the planned gas pipeline from Russia to Germany through the Baltic Sea known as Nord Stream. Although not yet realised, the project has, since its birth, been the subject of harsh criticism and opposition by a significant number of states that consider themselves affected by the pipeline. Whereas the Baltic States and Poland have interpreted the pipeline as a politically motivated strategy that will increase Russia's leverage on them and threaten their energy security, the debate in Sweden was at first mostly concerned with the prospect of increased Russian military presence in the Swedish Exclusive Economic Zone. The potential environmental impact of the pipeline has been, and continues to be, an overarching concern shared by all the littoral states of the Baltic Sea. Proponents of Nord Stream, most notably Germany, Russia and the Nord Stream consortium, have largely dismissed the concerns as unwarranted and argue that the pipeline is a common European project that all EU-members should embrace, as it will provide much-needed gas to an increasingly energy-thirsty union. This report is an extensive study of the divergent attitudes and debates that have surged in the region regarding Nord Stream, and the aim is to provide plausible explanations as to why the interpretations of the project have been so different in the various states. The report is based on a variety of sources, including several first-hand interviews with researchers and government officials in the Baltic Sea region. (author). refs.,fig.,tabs

Road map towards a common harmonised Nordic end-user market. NordREG report 5 - 2013

Energy Technology Data Exchange (ETDEWEB)

NONE

2013-07-01

The purpose of this road map is to describe the overall process to harmonise the Nordic electricity end-user markets. The main target groups for the road map are the Nordic governments, legislators and the electricity industry. The road map will continuously be updated as the project progresses, at least once a year. It describes the recommendations already made by NordREG, as well as indicates up-coming recommendations. One important part of the Nordic harmonisation process is the monitoring of the progress of the project. It will be communicated through national implementation monitoring overviews, which will describe the state of play for each recommendation made by NordREG. The road map highlights the importance of national commitment by different stakeholders, authorities and governments in order to successfully harmonise the Nordic end-user markets. This commitment is absolutely essential. The goal for 2015 is to harmonise some of the legislation, rules and processes that constitute barriers for suppliers to establish their business in other Nordic countries. In order to achieve this goal, NordREG is working towards defining responsibilities in the customer interface of the supplier centric model and the way of billing the customers. Another important task is related to development of an efficient way of communication among a large number of Nordic electricity companies. By 2015 the end-user markets should be harmonised to the extent that the most critical prerequisites have been achieved. But it is important to bear in mind that there are still many more steps to be taken also after 2015. The harmonisation process between the Nordic retail markets is a process that will continue for the foreseeable future. Since there is no supranational organisation or institution (like in the EU), it means that any future development of the Nordic retail market will have to be continuously coordinated between the Nordic countries to ensure that the markets maintain the

Nord Pool wants to be the leader in CO2

International Nuclear Information System (INIS)

Wellander, Dag

2004-01-01

In the beginning of 2005 Nord Pool introduces standard contracts for European emission rights for carbon dioxide. It is currently too early to speak of a global market for emission rights for greenhouse gases. The problem is not the attitude of the U.S.A., as is often said, but what road is taken by the so-called third world. The acceptance of the Kyoto Protocol by the Russians means that the agreement will come into force in 2005. It is much more important, however, what is going to happen after the first implementation period 2008 - 2012. In that process those countries that strive for one car per household must also be engaged. In particular the giant nations China and India must join the agreement if it is to be a notable climatic agreement of global scope

Introduction L'objectif de ce travail est de déterminer les fréquences alléliques et génotypiques des sites polymorphes situés dans le gène de l'apolipoprotéine E (apo E) ainsi que leur impact sur les paramètres cliniques et lipidiques dans un échantillon de la population du nord du Maroc cliniquement diagnostiqué ADH. Méthodes Le génotype de l'apo E a été analysé par séquençage direct chez 46 patients cliniquement diagnostiqués ADH selon les critères standards. Résultats Les fréquences des allèles epsilon 3, epsilon 2 et epsilon 4 ont été respectivement 78.3%, 2.2% et 19.6%. La fréquence de l'allèle epsilon 4 est très élevée chez la population du nord du Maroc en comparaison avec les populations des autres régions marocaines. Elle est similaire à celle rapportée dans les pays de l'Europe du nord. Les taux du cholestérol total, du cholestérol LDL ainsi que la présence des xanthomes et les maladies cardiovasculaires ne différent pas entre les génotypes de l'apoE. En revanche, les résultats ont montré une influence de l'allèle epsilon4 sur le taux des triglycérides chez les sujets obèses. Conclusion Le génotype de l'apoE ne peut expliquer le phénotype clinique et biochimique présenté par des patients du Nord du Maroc cliniquement diagnostiqués ADH. PMID:24396563

Taking energy efficiency to a new scale: the climate change action plan in Nord-Pas de Calais region

International Nuclear Information System (INIS)

Lafolie, Bertrand; Tillerson, Kenya

2005-01-01

Through the experience of a new climate change action plan in the French region 'Nord-Pas de Calais', the paper highlights the urgent necessity as well as the inherent difficulties for energy efficiency strategies to penetrate everyday practices and policies in order to reduce emissions in line with national and international commitments. Nord-Pas de Calais takes pride in two decades of sustained promotion of energy efficiency and renewable energy. Nevertheless, observation shows that regional consumption grows at roughly the same rate as does national consumption. The paper will present the history of energy efficiency in the region and relate the steps in elaborating a new climate change action plan that moves away from a focus on innovative projects towards the integration of easily replicable practices in business as usual. It then discusses some of the practical roadblocks that are faced in attempting to change the scale of achievements. Surprisingly, the main barrier met with until now seems not to be lack of interest and motivation towards energy efficiency from the general public but the way energy efficiency practitioners traditionally work and think eceee '005 Panel 2

Nord Stream, the German-Russian oil pipeline under the Baltic Sea from the Swedish point of view

Crone, Olivier

2007-01-01

Nord Stream is a 1.200 km long gas pipeline project between Russia and Germany through the Baltic Sea. It crosses the Swedish, Danish, and Finnish economic zones, and, at mid-way, comprises a control platform about which any traffic will be forbidden within a radius of 500 m. After having recalled some design aspects of this project, the author discusses whether it results in some energetic benefits for Sweden where the project has been a matter of debates on environmental and safety issues. It appears that Sweden is not interested at all in importing fossil energies, and that politicians are opposed to this project, but have no influence on it as the pipeline does not cross Swedish territorial waters. After having evoked the role of Gazprom as energetic weapon of the Russian foreign policy, the author discusses safety issues related to this pipeline and its control platform, and environmental risks as they are perceived by Sweden. Sweden indeed perceives the project infrastructure as being possibly used as a spying tool. As far as environmental issues are concerned, Nord Stream is to submit an environmental impact assessment to Denmark, Finland, Sweden, Germany and Russia. As a Swedish law could constrain and even impede the project, some alternate tracks are already envisaged and studied for the pipeline in order to minimise the environmental impact

Celle-ci fait échos des irrégularités de la langue de Voltaire dans la presse écrite de cette partie du pays. De plus en plus, on y assiste à une émergence des déviances syntaxiques et une profusion des écarts langagiers à connotation dépréciative. L’indécence verbale de la société, la mauvaise prestation des élèves en classe et lors des examens officiels en sont des indicateurs pertinents. Il est important de mentionner que la cohabitation entre les langues camerounaises et le français, la sous-scolarisation et ou l’ignorance, le laxisme des rédacteurs en chef, etc. sont les mobiles profonds de cette incorrection.

Commercial development of a new process of uraniferous ore sintering by pelletizing before dump leaching (wet process) application to a very clayey ore of Nord-Aquitaine

International Nuclear Information System (INIS)

Videau, G.; Roche, M.

1990-01-01

Much of the French uranium ore contains clay of sedimentary origin or derived from the alteration of rocks of the granite type. During a dump leaching operation by a wet process, these clays reduce the percolation rates and sometimes the percolation rates are so low that the very essence of the dump leaching operation can be called in question. This problem arises particularly for the treatment of the ore of Nord-Aquitaine. The results of tests, carried out at the SEPA in Bessines, have shown that after pelletizing clayey ores with sodium silicate in the presence of sulphuric acid for the polymerization of the silicate, the percolation rates were much increased. This new method was successfully applied, from a laboratory column to a pilot dump of 500 tonnes for the very clayey ore of Nord-Aquitaine. This ore of low grade (approx. 1000 ppm of U) seems to be difficult to upgrade by any other method of treatment in the present economic context [fr

The relationship between spot and futures prices in the Nord Pool electricity market

International Nuclear Information System (INIS)

Botterud, Audun; Kristiansen, Tarjei; Ilic, Marija D.

2010-01-01

We analyze 11 years of historical spot- and futures prices from the hydro-dominated Nord Pool electricity market. We find that futures prices tend to be higher than spot prices. The average convenience yield is therefore negative, but varies by season and depends on the storage levels in hydro reservoirs. The average realized return on holding a long position in the futures market is also negative. The negative convenience yield and risk premium contrast empirical findings in most other commodity markets. We argue that differences between the supply and demand sides in terms of risk preferences and the ability to take advantage of short-term price variations can contribute to explain the observed relationship between spot- and futures prices. In addition, our analysis shows that the relationship between spot and futures prices is clearly linked to the physical state of the system, such as hydro inflow, reservoir levels, and demand.

The authors discuss the difficulties encountered in the exploration of a typical deposit in the Nord-Limousin, using the resistivity measurement method. In the zone in question the over-thrust was very variable and difficult to predict. The uraniferous deposits had two types of aspect, the passage from one to the other being often very sudden: long thin veins without gangue; short and thick lens-shape deposits which were strongly contaminated by clay towards their edges. After several unsatisfactory attempts, the device known as the 'rectangular map' was adopted and gave an acceptable structural representation rapidly and cheaply. For the placing of the probes however, methods are required which are more refined and sensitive. It is in any case useless to expect to obtain a satisfactory representation and a sufficient accuracy using a single technique; especially in the region under consideration. (author) [French] Les auteurs exposent les difficultes rencontrees pour l'exploration, par la methode des mesures de resistivite, d'un gisement type du Nord-Limousin: il s'agissait d'une zone a recouvrement tres variable et difficilement previsible. Les occurences uraniferes y affectaient deux facies passant brutalement de l'un a l'autre: longs filonnets minces et sans gangue; lentilles courtes et puissantes avec alteration argileuses tres etendue aux epontes. Apres plusieurs essais peu satisfaisants, le dispositif dit 'carte des rectangles' a ete adopte pour obtenir rapidement et a bon compte un schema structural suffisant. Mais des methodes plus fines et plus sensibles sont necessaires pour guider l'implantation des sondages. Il est d'ailleurs vain d'esperer trouver a la fois la representativite d'ensemble et la precision, dans l'utilisation d'une seule technique, surtout dans la region envisagee. (auteur)

Nord Stream 2: May Cooler Heads Prevail

Aoun, Marie-Claire

2016-01-01

Since the announcement of the Nord Stream 2 project in June 2015, the debate around the benefits of this project for Europe is raging, putting forward political, economic and commercial arguments. Within the space of a few months, Russia has conducted a radical strategic change towards Europe in its gas policy. Following the announcements in 2014 of a major shift towards Asia, the cancellation of the South Stream project and its replacement by the Turkish Stream, relations with European gas companies have been strengthened since mid-2015. Russia's initiatives to replace its European partners are now to be viewed as part of a transformed international gas landscape. Tensions in the liquefied natural gas (LNG) market following Fukushima have given way to market surpluses. These are characterised on the one hand by lower growth in Asian demand for LNG gas, and on the other hand by the arrival on the market of new major exporters such as Australia and the United States. A new era, more favourable to gas importing countries, has opened up since the end of 2014. Moreover, the key pivot to Asia, expected by Moscow in 2014, is still far off. Discussions with Beijing about the project for a Western route proved to be more difficult than expected. Similarly, negotiations between Turkey and Russia on the Turkish Stream project have been very laborious, having been interrupted for several months because of diplomatic rows between the two countries. Finally, Russia's room for manoeuvre has narrowed, given the collapse in oil and gas prices and Western economic sanctions, which are weighing heavily on its economy. And the increased competitiveness of Russian oil companies due to the ruble devaluation will not transform this situation sustainably

The Nordic power exchange Nord pool and the Nordic model for a liberalised power market

International Nuclear Information System (INIS)

2000-01-01

As the first countries in the world, the Nordic countries Norway, Sweden, Finland and denmark have established a common, multinational power exchange. By means of this common power exchange, these countries also have established a common power market. this is also the first - and for the time being - the only place in the world, where you can find a multinational, truly competitive power market. This Nordic model has attracted much interest from other countries in Europe, Asia, North America and South America. The presentation will explain, how the common power exchange makes it possible for the four countries and the five system operators in Scandinavia physically and financially to operate a common, multinational, competitive power market. The presentation will explain how this systems works in the Nordic countries by discussion the following items: - The non-commercial players: The Transmission System Operators and the local grid operators; - The market players: the producers, the retailers, the traders, the brokers and the end users; - The access to the grid: The point tariff system; - The fairness towards the market players and the security of supply: The balancing power and the regulating power; - The power exchange handles bottlenecks in the grid. The presentation will explain how this is done and will demonstrate how this gives the power market a bottleneck handing method which:- Is neutral and fair towards all the market players, - Ensures that all the capacity of any bottleneck is utilised during every hour of operation, - Is extremely easy to use for the Transmission System Operators - also if the bottleneck is cross-border bottleneck; - The Nord Pool spot market Elspot; - The Nord Pool futures market Eltermin; - Area prices; - How financial contracts replace physical contracts when the power market is liberalised; - The day-to-day market and the market for long-term contracts in a liberalised power market; - How to eliminate the c ounter party risk

Estimation of the risk of radiation-induced leukaemia among young people in the vicinity of the La Hague reprocessing plant. Results from the nord-cotentin radioecological study

A radioecological study has been performed around the La-Hague nuclear reprocessing plant (Nord-Cotentin, France). The Working Group included nuclear operators, authorities, international experts and members of environmental organisations and was supported by IPSN. The study aimed to reconstruct radiation doses received by members of the public aged 0 to 24 years and living in the area, with a view to estimate the associated risk of leukaemia between 1978 and 1996. The assessment involved three steps: 1. reconstruction of a cohort of people aged 0 to 24 years, using local birth rates for the years 1954 to 1996 and taking into account the additional migrations of young people in the area. 2. estimation of doses to the red bone marrow received from all source of radiation (natural, medical, local nuclear industries and Chernobyl and weapons testing). Concentrations of radionuclides in the environment were estimated with a combination of two approaches: the modelling of the transfer of the releases in the environment and the use of environmental measurements. The dose computation takes into account the life style of the local population. ICRP dose coefficients to the red bone marrow were used. 3. derivation of leukaemia risk from a dose response model recommended by the UNSCEAR committee. The reconstructed population includes 6656 people born between 1954 and 1996, who inhabited the study area for at least one year between 1978 and 1996 before the age of 25. The number of person-years between 1978 and 1996 is 69308. The total collective dose to the red bone marrow due to local nuclear installations is 0.5 man.Sv. For the sake of comparison, the collective dose due to all sources of exposure is 241 man.Sv: The estimated number of leukaemia due to all exposure sources is 0.835. 74% are due to natural exposures, 24% to medical ones and 2% to the Chemobyl accident and nuclear arm testing. Nuclear facilities of Nord-Cotentin contribute only for 0.1% (between 0.0009 and 0

Caring for a spouse diagnosed with dementia can be a stressful situation and can put the caregiving partner at risk of loss of mental health and wellbeing. The main aim of this study was to investigate the relationship between dementia and spousal mental health in a population-based sample of married couples older than 55 years of age. The association was investigated for individuals living together with their demented partner, as well as for individuals whose demented partner was living in an institution. Data on dementia were collected from hospitals and nursing homes in the county of Nord-Trøndelag, Norway. These data were combined with data on spousal mental health, which were collected in a population-based health screening: the Nord-Trøndelag Health Study (HUNT). Of 6,951 participating couples (>55 years), 131 included one partner that had been diagnosed with dementia. Our results indicate that after adjustment for covariates, having a partner with dementia is associated with lower levels of life satisfaction and more symptoms of anxiety and depression than reported by spouses of elderly individuals without dementia. Spouses living together with a partner diagnosed with dementia experienced moderately lower levels of life satisfaction (0.35 standard deviation [SD]) and more symptoms of depression (0.38 SD) and anxiety (0.23 SD) than did their non-caregiving counterparts. Having a partner with dementia that resided in a nursing home was associated with clearly lower life satisfaction. Compared with non-caregivers, these spouses reported lower levels of life satisfaction (1.16 SD), and also more symptoms of depression (0.38 SD), and more symptoms of anxiety (0.42 SD). Having a partner with dementia is associated with loss of mental health and reduced life satisfaction. The risk of adverse mental health outcomes is greatest after the partner's nursing home admission.

The marine environment of the North Sea and Baltic Sea is still heavily polluted. The marine ecosystems are under severe stress from overfishing, water pollution, raw materials production and tourism. Environmental protection in this region necessitates decisive political initiatives and strict corrections especially in fishery policy, agricultural policy and chemical substances control. This is the balance of the special expert opinion of the Council of Environmental Experts. The publication specifies the main problem areas, the current pollution situation, the fields where action is most urgently required - especially in fishery, chemical substances, agricultural and sea travel policies - and presents suggestions for an integrated European and national marine protection policy including a regional development concept for the marine environment. (orig.) [German] Die Meeresumwelt von Nord- und Ostsee ist nach wie vor stark belastet. Ueberfischung, Schadstoffeintraege und Ueberduengung sowie die intensive Nutzung durch Schifffahrt, Rohstoffabbau und Tourismus beeintraechtigen vielfach massiv die marinen Oekosysteme. Ein wirksamer Meeresumweltschutz erfordert daher einschneidende politische Initiativen und grundlegende Korrekturen insbesondere in der Fischereipolitik, der Agrarpolitik und bei der Chemikalienregulierung. Diese Bilanz zieht der Rat von Sachverstaendigen fuer Umweltfragen in seinem aktuellen Sondergutachten 'Meeresumweltschutz fuer Nord- und Ostsee'. Das Sondergutachen - gibt einen Ueberblick ueber die wichtigsten Problemfelder und die aktuelle Belastungslage, - zeigt den wesentlichen Handlungsbedarf auf, insbesondere fuer die Fischerei-, Chemikalien-, Agrar- und Schifffahrtspolitik und - entwickelt Vorschlaege fuer eine integrierte europaeische und nationale Meeresschutzpolitik einschliesslich einer Merresraumordnung.

NKS-B NordRisk II: Nuclear risk from atmospheric dispersion in Northern Europe - Summary report

International Nuclear Information System (INIS)

Lauritzen, B.

2011-05-01

The objective of the NordRisk II project has been to derive practical means for assessing the risks from long-range atmospheric dispersion of radioactive materials. An atlas over different atmospheric dispersion and deposition scenarios has been developed using historical numerical weather prediction (NWP) model data. The NWP model data covers three years spanning the climate variability associated with the North Atlantic Oscillation, and the atlas considers radioactive releases from 16 release sites in and near the Nordic countries. A statistical analysis of the long-range dispersion and deposition patterns is undertaken to quantify the mean dispersion and deposition as well as the variability. Preliminary analyses show that the large-scale atmospheric dispersion and deposition is near-isotropic, irrespective of the release site and detailed climatology, and allows for a simple parameterization of the global dispersion and deposition patterns. The atlas and the underlying data are made available in a format compatible with the ARGOS decision support system, and have been implemented in ARGOS. (Author)

Application of resistivity measurements to research on structural elements in the Nord-Limousin (France) uraniferous basin (1960)

Sarcia, J.A.; Bonnet, J.; Combe, R.

1960-01-01

The authors discuss the difficulties encountered in the exploration of a typical deposit in the Nord-Limousin, using the resistivity measurement method. In the zone in question the over-thrust was very variable and difficult to predict. The uraniferous deposits had two types of aspect, the passage from one to the other being often very sudden: long thin veins without gangue; short and thick lens-shape deposits which were strongly contaminated by clay towards their edges. After several unsatisfactory attempts, the device known as the 'rectangular map' was adopted and gave an acceptable structural representation rapidly and cheaply. For the placing of the probes however, methods are required which are more refined and sensitive. It is in any case useless to expect to obtain a satisfactory representation and a sufficient accuracy using a single technique; especially in the region under consideration. (author) [fr

To study the prevalence and usefulness of audiometric notches in the diagnosis of noise-induced hearing loss (NIHL). Audiograms and data on noise exposure from 23,297 men and 26,477 women, aged 20 to 101 years, from the Nord-Trøndelag Hearing Loss Study, 1996-1998. The prevalence of four types of audiometric notches (Coles, Hoffman, Wilson) and 4 kHz notch were computed in relation to occupational noise exposure, age, sex, and report of recurrent ear infections. The prevalence of notches in the 3 to 6 kHz range (Wilson, Hoffman, and Coles) ranged from 50% to 60% in subjects without occupational noise exposure, and 60% to 70% in the most occupationally noise-exposed men. The differences were statistically significant only for bilateral notches. For 4 kHz notches, the prevalence varied from 25% in occupationally nonexposed to 35% in the most occupationally exposed men, and the differences were statistically significant for both bilateral and unilateral notches. For women, the prevalence of notches was lower than in men, especially for 4 kHz notches, and the differences between occupationally noise exposed and nonexposed were smaller. Recreational exposure to high music was not associated with notched audiograms. The detection of bilateral notches and unilateral 4 kHz notches is of some value in diagnosing NIHL, especially in men. 4 Laryngoscope, 127:1442-1450, 2017. © 2016 The Authors.

Bland, Alastair

1994-01-01

Control of the CERN SPS and LEP accelerators and service equipment on the two CERN main sites is performed via workstations, file servers, Process Control Assemblies (PCAs) and Device Stub Controllers (DSCs). This paper describes the methods and tools that have been developed to manage the file servers, PCAs and DSCs since the LEP startup in 1989. There are five operational DECstation 5000s used as file servers and boot servers for the PCAs and DSCs. The PCAs consist of 90 SCO Xenix 386 PCs, 40 LynxOS 486 PCs and more than 40 older NORD 100s. The DSCs consist of 90 OS-968030 VME crates and 10 LynxOS 68030 VME crates. In addition there are over 100 development systems. The controls group is responsible for installing the computers, starting all the user processes and ensuring that the computers and the processes run correctly. The operators in the SPS/LEP control room and the Services control room have a Motif-based X window program which gives them, in real time, the state of all the computers and allows them to solve problems or reboot them.

Full Text Available In order to develop strategies for controlling and reducing Arctic air pollution, there is a need to understand the basic mechanisms for determining the fate of air pollution in the Arctic. Sources of atmospheric particles at Station Nord (81° 36' N, 16° 40' W in North East Greenland were evaluated for a two-year period from March 2008 to February 2010. Source apportionment using Positive Matrix Factorization (PMF and COnstrained Physical REceptor Model (COPREM was based on measurements of black carbon, elements (Al, Si, S, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, As, Se, Br, Rb, Sr, Zr, Pb and inorganic ions (SO₂, SO₄²⁻, Na⁺, NH₄⁺, NO₃⁻, Cl²⁻. In general, source apportionment results by PMF and COPREM showed good agreement. Five sources adequately explained the measurements, which included a Marine and a Soil source of natural origin and three additional anthropogenic sources, which were all influenced by metal industries. One anthropogenic source was dominated by Zn of which air mass back trajectories using the Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT model suggested a Canadian Arctic origin, despite certain influences from Southern and Eastern origins. Another anthropogenic source was characterised by high concentrations of Pb and As, which has been historically referred to as a Combustion source at Station Nord. The impacts of large-scale industry in Siberia, Russia were evident through high Cu concentrations in both the Combustion source and an additional Cu/Ni source.

Br correlated well with the anthropogenic species S and Pb though the elements are unlikely to have a common origin. More likely, sulphuric acid aerosols serve as transport containers for Br species of marine origin. Of particular relevance to climate, sources of black carbon were identified to be

CAMAC-an international standard for data machine instrumentation

CERN Document Server

Johnsen, P J

1973-01-01

CAMAC is a standard for on-line computer instrumentation and control. Owing to the world-wide acceptance of CAMAC, standardized and mutually compatible equipment is now offered by a great number of manufacturers. CAMAC systems are modular, and with the range of modules commercially available, it is possible to build up flexible and complex data processing systems. Use of CAMAC requires a CAMAC- compatible entrance (interface) to the computer. Once established, users are later on completely independent of the type of computer used. General aspects, CAMAC systems for NORD-1 and NORD-10 are presented. The former is developed at Physics Institute, Oslo, and the latter is developed as a result of the CERN-contract gained by NORSK DATAELEKTRONIKK.

Full Text Available L’une des caractéristiques récentes de la Corée du Nord est le manque manifeste d’intégration territoriale, en contradiction croissante avec la volonté d’ouverture économique. Dans un environnement mondialisé, le faible coût et la qualité de sa main-d’œuvre, l’abondance des ressources naturelles, et une situation stratégique entre la Corée du Sud, le Japon et leurs voisins continentaux immédiats comme la Chine et la Russie, sont autant d’atouts qui devraient permettre la mise en œuvre des réformes et la relance de l’économie. Tandis que la plupart des travaux précédents se basent sur les facteurs politiques externes pour expliquer les difficultés rencontrées (isolement dû à la disparition du bloc de l’Est, embargo imposé par les États-Unis et le Japon, cet article privilégie les facteurs spatiaux internes.

Bilateral contracts and the spot market for electricity: some observations on the British and the NordPool experiences

International Nuclear Information System (INIS)

Herguera, Inigo

2000-01-01

The performance of the futures and the spot market for electricity in England and Wales (EW) and in the Nordic countries have significant differences in terms of volumes traded and evolution of prices. Even though the institutional arrangements show significant differences and the data collected has important limitations we observe in EW for 1990-199 that as the coverage via bilateral contracts diminished, spot prices tended to increase, there was higher price volatility and an increasing number of plants were declared unavailable. In the NordPool, by contrast, market structure is more distributed, the bilateral contract price has tended to smooth the volatility in the spot price and a very diverse pattern behavior of prices has been observed. We interpret these observations as additional support in favor of the theoretical result by and Vila (Journal of Economic Theory 59 (1993) 1), but hint at the possibility of strategies by the firms that can diminish the welfare enhancing properties of this new bilateral market.

Are electricity risk premia affected by emission allowance prices? Evidence from the EEX, Nord Pool and Powernext

International Nuclear Information System (INIS)

Daskalakis, George; Markellos, Raphael N.

2009-01-01

The links between emission and energy markets are of great interest to practitioners, academics and policy makers. In this paper, it is conjectured that a positive relationship exists between emission allowance spot returns and electricity risk premia within the European Union Emissions Trading Scheme (EU ETS). We discuss how this can be justified on the basis of the substantial uncertainties in the carbon markets. We also argue that this link could be due to trading strategies followed by electricity producers who attempt to exploit their initial allocation of free allowances. Analysis of data from three major markets, the EEX, Nord Pool and Powernext, offers empirical support to our conjecture. These findings have significant policy implications since they imply that efforts should be made in order to reduce the uncertainty in the carbon markets by clearly defining the EU ETS regulative framework and design over the next years. Moreover, our results suggest that the allocation of free allowances and their unrestricted trading enable electricity producers to accomplish windfall profits in the derivatives market at the expense of other market participants.

Timing of metamorphism and exhumation in the Nordøyane ultra-high-pressure domain, Western Gneiss Region, Norway: New constraints from complementary CA-ID-TIMS and LA-MC-ICP-MS geochronology

Science.gov (United States)

Butler, J. P.; Jamieson, R. A.; Dunning, G. R.; Pecha, M. E.; Robinson, P.; Steenkamp, H. M.

We present the results of a combined CA-ID-TIMS and LA-MC-ICP-MS U-Pb geochronology study of zircon and associated rutile and titanite from the Nordøyane ultra-high-pressure (UHP) domain in the Western Gneiss Region (WGR) of Norway. The dated samples include 4 eclogite bodies, 2 host-rock migmatites, and 2 cross-cutting pegmatites and leucosomes, all from the island of Harøya. Zircon from a coesite eclogite yielded an age of ca. 413 Ma, interpreted as the time of UHP metamorphism in this sample. Zircon data from the other eclogite bodies yielded metamorphic ages of ca. 413 Ma, 407 Ma, and 406 Ma; zircon trace-element data associated with 413 Ma and 407 Ma ages are consistent with eclogite-facies crystallization. In all of the eclogites, U-Pb dates from zircon cores, interpreted as the times of protolith crystallization, range from ca. 1680-1586 Ma, consistent with Gothian ages from orthogneisses in Nordøyane and elsewhere in the WGR. A zircon core age of ca. 943 Ma from one sample agrees with Sveconorwegian ages of felsic gneisses and pegmatites in the western part of the area. Migmatites hosting the eclogite bodies yielded zircon core ages of ca. 1657-1591 Ma and rim ages of ca. 395-392 Ma, interpreted as the times of Gothian protolith formation and Scandian partial melt crystallization, respectively. Pegmatite in an eclogite boudin neck yielded a crystallization age of ca. 388 Ma, interpreted as the time of melt crystallization. Rutile and titanite from 3 samples (an eclogite and two migmatites) yielded concordant ID-TIMS ages of 378-376 Ma. The results are similar to existing U-Pb data from other Nordøyane eclogites (415-405 Ma). In combination with previous pressure-temperature data from the coesite eclogite, these ages indicate that peak metamorphic conditions of 3 GPa/760 °C were reached ca. 413 Ma, followed by decompression to 1 GPa/810 °C by ca. 397 Ma and cooling below ca. 600 °C by ca. 375 Ma. The results are compatible with protracted UHP

The regulating power market on the Nordic power exchange Nord Pool. An econometric analysis

International Nuclear Information System (INIS)

Skytte, K.

1999-08-01

What differentiates the structure of Nord Pool from other power exchanges around the world is the way the balance from the spot market is maintained until the actual, physical delivery takes place, via the regulating power market in Norway. This paper reveals the pattern of the prices on the regulating power market, by analysing the cost of being unable to fulfil the commitments made on the spot market. Some power producers with unpredictable fluctuations (e.g. wind) will need to buy regulation services. The disclosed pattern implies that these producers must pay a limited premium of readiness in addition to the spot price; this premium is independent of the amount of regulation. The level of the premium of readiness for down-regulation is shown to be strongly influenced by the level of the spot price. On the other hand, it is demonstrated that the premium for up-regulation is less correlated to the spot price. Furthermore, it is found that the amount of regulation affects the price of regulating power for up-regulation more strongly than it does for down-regulation. The disclosed cost of using the regulating power market is a quadratic function of the amount of regulation. This asymmetric cost may encourage bidders with fluctuating production to be more strategic in their way of bidding on the spot market. By using such strategies the extra costs (for example wind power) needed to counter unpredictable fluctuations may be limited. 12 refs

Introduction L'eau est utilisée d'une façon primordiale dans tout le processus de la fabrication des produits alimentaires. Les industries agroalimentaires du Nord du Maroc utilisent différentes sources d'eaux mais l'eau de réseau public et l'eau de puits sont les principales sources d'eau utilisée. Cette eau peut s'avérer la source principale des éventuelles contaminations et altérations des aliments. Notre but est d'évaluer la qualité bactériologique de l'eau utilisée par les industries agroalimentaires dans la région du Nord du Maroc, d'identifier les différents germes responsables de la pollution de ces eaux et de définir les principales causes de cette pollution. Méthodes Des échantillons d'eau prélevés aux robinets ou des puits ont été analysés pour la recherche des germes indicateurs de la pollution (coliformes totaux (CT), coliformes fécaux (CF), entérocoques intestinaux (E), microorganismes revivifiables (MOR), anaérobies sulfitoréducteurs) et les germes pathogènes (Salmonelles, Staphylocoques, Pseudomonas aeruginosa). Le dénombrement des bactéries a été fait par la technique de filtration et par incorporation en milieu solide en surfusion. Résultats Les résultats ont montré que les eaux du réseau public ont été de qualité bactériologique satisfaisante tandis que 40% des eaux des puits ont été non conformes aux normes à cause de la présence des indicateurs de pollution CT, CF, E et MOR. En revanche, les germes pathogènes, en particulier les Salmonelles, ont été absents dans les eaux de tous les puits analysés. Conclusion La pollution de ces puits a été généralement liée au non-respect des conditions de puisage hygiéniques. La qualité bactériologique des eaux de ces puits peut être améliorée par une protection adéquate. PMID:28450992

Full Text Available This work presents an analysis of the physical properties of sub-micrometer aerosol particles measured at the high Arctic site Villum Research Station, Station Nord (VRS, northeast Greenland, between July 2010 and February 2013. The study focuses on particle number concentrations, particle number size distributions and the occurrence of new particle formation (NPF events and their seasonality in the high Arctic, where observations and characterization of such aerosol particle properties and corresponding events are rare and understanding of related processes is lacking.A clear accumulation mode was observed during the darker months from October until mid-May, which became considerably more pronounced during the prominent Arctic haze months from March to mid-May. In contrast, nucleation- and Aitken-mode particles were predominantly observed during the summer months. Analysis of wind direction and wind speed indicated possible contributions of marine sources from the easterly side of the station to the observed summertime particle number concentrations, while southwesterly to westerly winds dominated during the darker months. NPF events lasting from hours to days were mostly observed from June until August, with fewer events observed during the months with less sunlight, i.e., March, April, September and October. The results tend to indicate that ozone (O3 might be weakly anti-correlated with particle number concentrations of the nucleation-mode range (10–30 nm in almost half of the NPF events, while no positive correlation was observed. Calculations of air mass back trajectories using the Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT model for the NPF event days suggested that the onset or interruption of events could possibly be explained by changes in air mass origin. A map of event occurrence probability was computed, indicating that southerly air masses from over the Greenland Sea were more likely linked to those

A first part presents the methods used for this study, the hypotheses selected to elaborate scenarios, the presentation, results and comparison of various scenarios, and an assessment of energy imports. The second part addresses the different renewable energy resources of the region and their potential to reach the expected results. The third part reports the study of the evolution of transport organisation by 2050: pollutions related to transports, regional costs of these pollutions, dysfunctions and possible actions in the competition between transports modes (road, rail, river, sea, air). A chapter then addresses the issue of the relationship between urban planning and mobility. The next chapter discusses the possibilities of action in the building sector (housing and office building, policies to be implemented to comply with the chosen scenario). The possibilities of solar energy are then discussed

Piasecki, M.A.; Cliff, R.A.

1988-01-01

In the Bjugn district of the northern part of the Western Gneiss Region, Nord-Troendelag, a basement gneiss-cover nappe boundary is marked by a thick zone of ductile shearing. In this zone a layer-parallel mylonitic fabric with related new mineral growth overprints and retrogresses a previous fabric associated with a granulite facies mineral assemblage. Related minor shear belts contain abundant new minerals and vein systems, including pegmatites, believed to represent strain-induced products formed at the time of the shearing movements. Central parts of two large muscovite books from such a pegmatite yielded Rb-Sr, Early to Middle Devonian ages of 389±6 Ma and 386±6 Ma, interpreted as indicating the approximate time of pegmatite formation and of the shearing. Small, matrix-size muscovite and biotite grains from the host mylonite gave ages of 378±6 Ma and 365±5 Ma, respectively, supposed to relate to post-shearing uplift and cooling

Spouses tend to have similar lifestyles. We explored the degree to which spouse similarity in alcohol use, smoking, and physical exercise is caused by non-random mating or convergence. We used data collected for the Nord-Trøndelag Health Study from 1984 to 1986 and prospective registry information about when and with whom people entered marriage/cohabitation between 1970 and 2000. Our sample included 19,599 married/cohabitating couples and 1,551 future couples that were to marry/cohabitate in the 14-16 years following data collection. All couples were grouped according to the duration between data collection and entering into marriage/cohabitation. Age-adjusted polychoric spouse correlations were used as the dependent variables in non-linear segmented regression analysis; the independent variable was time. The results indicate that spouse concordance in lifestyle is due to both non-random mating and convergence. Non-random mating appeared to be strongest for smoking. Convergence in alcohol use and smoking was evident during the period prior to marriage/cohabitation, whereas convergence in exercise was evident throughout life. Reduced spouse similarity in smoking with relationship duration may reflect secular trends.

The aim of this study was to investigate the association between DM, non-fasting glucose and chronic MSCs defined as pain and/or stiffness ≥ 3 months during the past year in the general adult population. Methods The results were based on cross-sectional data from 64,785 men and women (aged ≥ 20 years who participated in the Nord-Trøndelag Health Survey, which included 1,940 individuals with known DM. Associations were assessed using multiple logistic regression, estimating prevalence odds ratio (OR with 95% confidence intervals (CIs. Results High non-fasting glucose was associated with a lower prevalence of chronic MSCs compared to a low glucose level. DM was associated with higher prevalence of chronic MSCs, in particular chronic widespread MSCs. In the multivariate analysis, adjusting for glucose level, BMI, age, gender and physical activity, chronic widespread MSCs was 1.6 times more likely (OR = 1.6, 95% CI 1.2–2.2 among individuals Conclusion In this cross-sectional study a high non-fasting glucose was associated with lower prevalence of chronic MSCs. Among individuals with known DM chronic widespread MSCs were more likely.

The ''Société Géologique du Nord'', located in Lille, in northern France, was founded in 1870, with Jules Gosselet as the first president. It has always been closely connected to the geology department of the Faculty of Sciences of Lille, now called the ''Université de Lille Sciences et Technologies'', and keeps strong links with the Natural History Museum of Lille. Its activities and evolution were closely related to those of the coal-mining basin of the area until the last shaft was closed in 1990. Its activities are both in the fields of applied and fundamental geosciences. From its beginning, the Society has published the results of the research of its members, both in a periodical journal, the Annales, and as monographies called Mémoires. From the 1970s, the Mémoires have been progressively replaced by Publications, mostly devoted to State doctoral theses. During the transition from the 20th to the 21st century, the activities of the Society have strongly declined, due to several internal and external factors. Since the beginning of the 21st century, the SGN has tried to adapt itself to the new conditions of both the university and the regional territory. It is still a scientific society, but it is open to its social environment. (Author) [French] La « Société Géologique du Nord » tiene su sede en Lille, en el norte de Francia.

Coal mining activity in the Nord-Pas-de-Calais region (Northern France) has generated many mine spoils. The oxidation of the pyrite content of such coal shales and their leaching can be a source of sulfate pollution for the underlying chalk aquifer, i.e. the main drinking water resource of the region. Two sites of study have been retained: one in the free water table zone and the other in the confined water table zone. Samples from both mine spoils have been analyzed with respect to their carbon and sulfur content and a superficial leaching of these elements has been evidenced. Water has been sampled in piezometers and boreholes close to the mine spoils and also along natural flux lines. The use of sulfur isotopes as markers of the different sulfate sources has confirmed the spoils source but has permitted to identify another source in the second site which is the Tertiary gypsum-bearing Ostricourt sands. This study has shown also that in the confined water table zone, part of the exported sulfates is reduced. This bacterial reduction of sulfates is due to a joint leaching of both carbon and sulfur in the mine spoils. A self-purification phenomenon occurs when the chalk aquifer is confined beneath the Cenozoic cover. (J.S.)

Whiplash injuries show a variable prognosis which is difficult to predict. Most individuals experiencing whiplash injuries rapidly recover but a significant proportion develop chronic symptoms and ongoing disability. By employing longitudinal data, we investigated how psychological and physical symptoms, self-rated health, use of health services and medications, health behavior and demographic factors predict recovery from whiplash. Data from two waves of a large, Norwegian, population-based study (The Nord-Trøndelag Health Study: HUNT2 and HUNT3) were used. Individuals reporting whiplash in HUNT2 (baseline) were identified in HUNT3 11 years later. The characteristics of individuals still suffering from whiplash in HUNT3 were compared with the characteristics of individuals who had recovered using Pearson's chi-squared test, independent sample t-tests and logistic regression. At follow-up, 31.6 % of those reporting whiplash at baseline had not recovered. These individuals (n = 199) reported worse health at baseline than recovered individuals (n = 431); they reported poorer self-rated health (odds ratio [OR] = 3.12; 95 % confidence interval [CI], 2.20-4.43), more symptoms of anxiety (OR = 1.70; 95 % CI, 1.15-2.50), more diffuse somatic symptoms (OR = 2.38; 95 % CI, 1.61-3.51) and more musculoskeletal symptoms (OR = 1.21; 95 % CI, 1.13-1.29). Individuals still suffering from whiplash also visited more health practitioners at baseline (OR = 1.18; 95 % CI, 1.06-1.32) and used more medications (OR = 1.24; 95 % CI, 1.09-1.40). Poor self-rated health seems to be a strong risk factor for whiplash injuries becoming chronic. Diffuse somatic symptoms, musculoskeletal symptoms and symptoms of anxiety at baseline are important prognostic risk factors. Knowledge of these maintaining risk factors enables identification of individuals at risk of non-recovery, facilitating adequate treatment for this vulnerable group.

Seule une étude détaillée de stratigraphie sismique le long de profils régionaux passant par des forages permet de contraindre les différents paramètres servant au calcul de la subsidence. L'étude de la subsidence du Viking Graben a mis en évidence trois épisodes : - phase de distension permo-triasique (saalienne ? dont l'axe de subsidence est décalé vers l'est par rapport à l'axe actuel du Viking Graben; - phase de distension jurassique supérieur (cimmérienne qui crée les structures majeures de cette zone; - phase paléocène correspondant au contrecoup de l'ouverture plus à l'ouest de l'Atlantique Nord. Cette phase est surtout sensible à l'ouest de la zone étudiée. Les cartes de subsidence pour les différentes époques font apparaître l'influence du bati calédonien. Deux directions principales apparaissent, une NE-SW correspondant aux directions structurales visibles à terre en Ecosse et une NW-SE discrète qui sépare le Southern Viking Graben du Northern Viking Graben. Cette dernière direction pourrait se calquer sur la suture (au Silurien d'un diverticule de l'océan lapétus, la Tornquist Sea.

The marine climate of the North Sea and Baltic Sea was simulated and analyzed with the aid of meteorological and oceanographic models. The KLINO project is a first step towards climate impact research as sensitivity studies of the models permit preliminary statements on the effects of potential changes of marine climate. The simulations covered several decades. The models used were: WAM for calculating the swell of the Atlantic and the two marginal seas; HAMSOM for climate-induced variations of the hydrographic parameters of the NOrth Sea and Baltic Sea; HAMSOM and REMO for interactive coupling between ocean and atmosphere; HYDROMOD for extreme and normal conditions in the offshore region. [German] Im Projekt KLINO wurde das derzeitige marine Klima (Wasserstaende und mittlerer Meeresspiegel, Seegang, Stroemungen und Schichtung) von Nord- und Ostsee in Kontrollexperimenten mit Hilfe meteorologischer und ozeanographischer Modelle simuliert und nach vollzogen. Das KLINO Projekt ist in die Arbeiten zur Klima-Regionalisierung bzw. als ein erster Schritt zur Klima-Impaktforschung einzustufen, da Sensitivitaetsstudien der Modelle bereits vorsichtige Aussagen ueber die Folgen moeglicher Aenderungen des marinen Klimas zulassen. Das WAM-Modell lieferte eine Klimatologie des Seeganges fuer den Atlantik und die beiden Randmeere. Die klimainduzierten Schwankungen der hydrographischen Parameter in Nord- und Ostsee wurden mit Hilfe des HAMSOM untersucht; eine interaktive Kopplung zwischen Ozean und Atmosphaere erfolgte mit den Regionalmodellen HAMSOM und REMO.

Full Text Available La Salmonella è un importante agente patogeno responsabile di zoonosi di notevole rilevanza economica. In Europa la salmonellosi è la seconda infezione trasmessa per via alimentare, in Italia il microrganismo continua ad essere la causa più frequente di infezione alimentare. In Europa sono in atto molti piani di sorveglianza di Salmonella in animali da allevamento, tuttavia il monitoraggio del microrganismo in animali selvatici è effettuato solo occasionalmente. Lo studio ha avuto l'obiettivo di indagare la presenza di Salmonella in animali selvatici e i ceppi antibiotico-resistenti. Nel periodo 2002-2010, 2.713 animali selvatici (Canidi, Mustelidi, Uccelli, Roditori e Ungulati, provenienti da aree dell'Italia nord-occidentale, sono stati testati per Salmonella mediante metodo microbiologico colturale seguito da tipizzazione sierologica e biochimica. Di questi, 117 (63 Canidi, 25 Mustelidi, 24 Uccelli, 5 Ungulati sono risultati positivi per Salmonella (4,3%. Sono stati isolati 130 ceppi appartenenti a diversi sierotipi e Salmonella Typhimurium è risultato quello più rappresentato. La sensibilità agli antibiotici è stata testata su 88 ceppi con test di disco-diffusione. La maggior parte dei ceppi analizzati (97,7% si sono mostrati intermedi (I o resistenti (R ad almeno una classe di antibiotici. I più alti valori sono stati osservati per la classe delle tetracicline. La presenza di sierotipi di Salmonella antibiotico-resistenti e responsabili di zoonosi è stata riscontrata in diverse specie di animali selvatici.

Developpement D'un Modele Climatique Regional: Fizr Simulation des Conditions de Janvier de la Cote Ouest Nord Americaine

Le sujet de cette these concerne la modelisation numerique du climat regional. L'objectif principal de l'exercice est de developper un modele climatique regional ayant les capacites de simuler des phenomenes de meso-echelle spatiale. Notre domaine d'etude se situe sur la Cote Ouest nord americaine. Ce dernier a retenu notre attention a cause de la complexite du relief et de son controle sur le climat. Les raisons qui motivent cette etude sont multiples: d'une part, nous ne pouvons pas augmenter, en pratique, la faible resolution spatiale des modeles de la circulation generale de l'atmosphere (MCG) sans augmenter a outrance les couts d'integration et, d'autre part, la gestion de l'environnement exige de plus en plus de donnees climatiques regionales determinees avec une meilleure resolution spatiale. Jusqu'alors, les MCG constituaient les modeles les plus estimes pour leurs aptitudes a simuler le climat ainsi que les changements climatiques mondiaux. Toutefois, les phenomenes climatiques de fine echelle echappent encore aux MCG a cause de leur faible resolution spatiale. De plus, les repercussions socio-economiques des modifications possibles des climats sont etroitement liees a des phenomenes imperceptibles par les MCG actuels. Afin de circonvenir certains problemes inherents a la resolution, une approche pratique vise a prendre un domaine spatial limite d'un MCG et a y imbriquer un autre modele numerique possedant, lui, un maillage de haute resolution spatiale. Ce processus d'imbrication implique alors une nouvelle simulation numerique. Cette "retro-simulation" est guidee dans le domaine restreint a partir de pieces d'informations fournies par le MCG et forcee par des mecanismes pris en charge uniquement par le modele imbrique. Ainsi, afin de raffiner la precision spatiale des previsions climatiques de grande echelle, nous developpons ici un modele numerique appele FIZR, permettant d'obtenir de l'information climatique regionale valide a la fine echelle spatiale

Chemical and isotopic tracing of underground water in relation with leaching of mine spoils, Nord-Pas-de-Calais Coal Basin (France)

Coal mining activity in the Nord-Pas-de-Calais region (Northern France) has generated many mine spoils. The oxidation of the pyrite content of such coal shales and their leaching can be a source of sulfate pollution for the underlying chalk aquifer, i.e. the main drinking water resource of the region. Two sites of study have been retained: one in the free water table zone and the other in the confined water table zone. Samples from both mine spoils have been analyzed with respect to their carbon and sulfur content and a superficial leaching of these elements has been evidenced. Water has been sampled in piezometers and boreholes close to the mine spoils and also along natural flux lines. The use of sulfur isotopes as markers of the different sulfate sources has confirmed the spoils source but has permitted to identify another source in the second site which is the Tertiary gypsum-bearing Ostricourt sands. This study has shown also that in the confined water table zone, part of the exported sulfates is reduced. This bacterial reduction of sulfates is due to a joint leaching of both carbon and sulfur in the mine spoils. A self-purification phenomenon occurs when the chalk aquifer is confined beneath the Cenozoic cover. (J.S.)

To explore longitudinally gender differences in the associations between psychosocial functioning, subjective well-being and self-esteem among adolescents with and without symptoms of anxiety and depression. Data were obtained from a major population-based Norwegian study, the Nord-Trøndelag Health Study, in which 1,092 boys and 1,262 girls (86% of all invited) completed an extensive self-report questionnaire at baseline (mean age 14.4 years) and at follow-up (mean age 18.4 years). Gender was a moderator variable in the associations between symptoms of anxiety and depression and impairment, meaning that boys' functioning was impaired to a larger extent than girls' functioning. A statistically significant interaction effect between gender and symptoms of anxiety and depression was found at follow-up in terms of subjective well-being (p self-esteem (p self-esteem than boys who had no symptoms at both time points. No similar differences were found among the girls. Previous and ongoing symptoms of anxiety and depression had more negative consequences for boys than for girls. These findings may contribute to improved assessment and intervention methods tailored differently for each gender.

Vers le nord, elle disparaît sous la mer; vers le sud, elle affleure largement dans la moitié nord de la Mesaoria jusque dans la région de i'Ovgos Potamos. Une étude lithologique et micropaléontologique a permis d'y distinguer 9, unités cartographiques correspondant à une échelle stratigraphique qui va de l'Eocène supérieur (? au Messinien évaporitique. Le Pliocène transgressif inaugure un nouveau cycle de sédimentation. Plusieurs biozones de Foraminifères planctoniques ont été reconnues. Leur succession dans le temps est sensiblement analogue à celle déjà distinguée en Méditerranée occidentale depuis l'Oligocène jusqu'au Pliocène moyen. La formation de Kithréa appartient à deux domaines paléogéographiques séparés par l'importante faille de Kithréa, de direction E-O. Au nord, dans un domaine « pentadaktylien », une série relativement diversifiée se dépose en transgression sur la chaîne. Au sud, dans un domaine « mésaorien », la série sédimentaire repose en concordance sur des dépôts crayeux qui s'étendent, vers le sud, jusqu'au Troodos.

The study aimed to investigate potential adolescent and parental psychosocial risk and protective factors for psychological distress among adolescents and, in addition, to examine potential gender and age differences in the effects of risk factors on adolescent psychological distress. Data were collected among 8,984 Norwegian adolescents (13-19 years) and their parents in the Nord-Trøndelag Health Study (HUNT). The outcome measure was psychological distress (SCL-5). Bivariate regression analysis with generalized estimating equation (GEE) model showed that all parental self-reported variables (mental distress, substance use, social network, economic problems, unemployment and family structure) and adolescents' self-reported variables (leisure activities, social support from friends, school-related problems and substance use) were significantly associated with psychological distress among adolescents. Results revealed that in a multiple regression analysis with a GEE model, adolescent psychosocial variables, specifically academic-related problems and being bullied at school, emerged as the strongest predictors of psychological distress among adolescents after controlling for age, gender, and all parental and adolescent variables. The following psychosocial risk factors were significantly more important for girl's psychological distress compared to boys: problems with academic achievement, conduct problems in school, frequency of being drunk, smoking, dissatisfaction in school, living alone and seen parents being drunk. Academic achievement and being bullied at school were the psychosocial factors most strongly associated with psychological distress among adolescents. Parental factors had an indirect effect on adolescent psychological distress, through adolescents' psychosocial factors.

En revanche, l’analyse du contenu des pixels en vue d’une modélisation statistique s’appuie sur une description thématique détaillée de points localisés très précisément.

Full Text Available Cet article passe en revue les différents modèles, depuis celui de l’école de Chicago jusqu’à celui de l’école de Los Angeles, qui représentent la forme des métropoles nord-américaines. L’analyse des métaphores, tant écologique ou gravitaire, que celles de la géographie des espaces-temps, des scènes urbaines ou du jeu keno, permet de revoir les termes du débat opposant le modèle gravitaire à celui de la métropole fragmentée. Deux questions sont ici soulevées. La première concerne l’unité des études urbaines contenue dans le modèle écologique, c’est-à-dire sa capacité de traiter de l’organisation de l’espace métropolitain et des interactions sociales réalisées à l’échelle du lieu. La seconde traite de la mobilité des personnes, c’est-à-dire de la relation entre l’organisation de l’espace métropolitain et l’espace vécu des individus. Deux constats se dégagent de l’analyse. Le premier est pour reconnaître le caractère inachevé de l’urbanisme postmoderne. La seconde souligne l’absence d’une métaphore de substitution pouvant  rendre compte de manière générale de la forme métropoles nord-américaines contemporaines.

Full Text Available Abstract Background Education-based inequalities in health are well established, but they are usually studied from an individual perspective. However, many individuals are part of a couple. We studied education-based health inequalities from the perspective of couples where indicators of health were measured by subjective health, anxiety and depression. Methods A sample of 35,980 women and men (17,990 couples was derived from the Norwegian Nord-Trøndelag Health Study 1995–97 (HUNT 2. Educational data and family identification numbers were obtained from Statistics Norway. The dependent variables were subjective health (four-integer scale, anxiety (21-integer scale and depression (21-integer scale, which were captured using the Hospital Anxiety and Depression Scale. The dependent variables were rescaled from 0 to 100 where 100 was the worst score. Cross-sectional analyses were performed using two-level linear random effect regression models. Results The variance attributable to the couple level was 42% for education, 16% for subjective health, 19% for anxiety and 25% for depression. A one-year increase in education relative to that of one’s partner was associated with an improvement of 0.6 scale points (95% confidence interval = 0.5–0.8 in the subjective health score (within-couple coefficient. A one-year increase in a couple’s average education was associated with an improvement of 1.7 scale points (95% confidence interval = 1.6–1.8 in the subjective health score (between-couple coefficient. There were no education-based differences in the anxiety or depression scores when partners were compared, whereas there were substantial education-based differences between couples in all three outcome measures. Conclusions We found considerable clustering of education and health within couples, which highlighted the importance of the family environment. Our results support previous studies that report the mutual effects of spouses on

There are very few permanent indicators of mental health in France; suicidal behavior is often only understood on the basis of deaths by suicide. The epidemiological interest and methodological limits of four medico-administrative databases from which data on suicide attempts can be extracted have been the subject of a study in the Nord - Pas-de-Calais Region of France: telephone calls for emergency medical assistance after suicide attempt (2009 to 2011), admissions in emergency services with a diagnosis of suicide attempt (2012), medical-surgical hospital admissions as a result of suicide attempt (2009 to 2011), and psychiatric admissions with a diagnosis of suicide attempt (2011). Usable data were provided by one of two emergency medical assistance units, five of thirty emergency departments and all medical-surgical and psychiatric units; in data from the latter two sources, a unique anonymous identifier gave individual statistics, while the first two covered only suicide attempts. In 2011, the number of suicide attempt calls per 100,000 inhabitants was 304, whereas the number of hospitalisations with this diagnosis was 275; rates are highest in men between 20 and 49 years of age, and in women below 20 years of age and between 40 and 49. Sources are seen to be very homogeneous with regards to the average age at which suicide took place (between 37.8 and 38.5 years, depending on the source), and to the sex (55.0% to 57.6% of women). In 2011, the number of patients with a diagnosis of suicide attempt treated in psychiatry is 2.6 times lower than the number hospitalised for suicide attempt in medical-surgical units (3563 vs 9327). Permanent gathering of data, and the large volume of data recorded, should encourage the use of these databases in the definition and assessment of mental health policy: an increased contribution from emergency call centers and emergency services, and the coding of the suicidal nature of intoxications by a few clearly under-declaring units

The impact of headache and chronic musculoskeletal complaints on the risk of insomnia: longitudinal data from the Nord-Trøndelag health study

Science.gov (United States)

2013-01-01

Background A strong relationship between insomnia and painful disorders has been found, but it is still unclear whether chronic pain leads to insomnia. There is a need of large-scale prospective studies to evaluate if there is a causal relationship between painful disorders and insomnia. Methods All inhabitants aged ≥ 20 years in Nord-Trøndelag County of Norway were invited to participate in two surveys (n = 92,566 and 93,860, respectively). 27,185 subjects participated in both surveys, and 19,271 of these were insomnia-free at baseline (population at risk). Using logistic regression, we evaluated the influence of headache, CMSCs and coexisting headache and CMSCs on the subsequent risk of insomnia. Results Compared to subjects without headache and CMSCs, there was an increased risk of insomnia among those with headache, most pronounced among those with headache ≥ 7 days / month (OR = 2.2, 95% CI = 1.9 – 2.6). Similarly, an increased risk among those with CMSCs was found, most evident for those with widespread CMSCs (OR = 2.0, 95% CI = 1.8 – 2.2). Having coexistent CMSCs and headache (OR = 2.0, 95% CI = 1.8 – 2.2) predisposed more strongly to insomnia than having headache (OR = 1.5, 95% CI = 1.3 – 1.6) and CMSCs (OR = 1.6, 95% CI = 1.4 – 1.7) alone. Conclusion In this prospective study headache and CMSCs were risk factors for insomnia 11 years later. PMID:23566158

Pour caractériser l’aléa sismique de la région andine, nous avons fait une révision critique de la sismicité historique et de l’ensemble des failles actives de l’Équateur. Les deux sources majeures de l’aléa sismique sont respectivement la subduction superficielle pour la région côtière et le système transpressif des hautes Andes pour la région andine. Ce système est composé de failles décrochantes dextres d’orientation N30-35°E (failles du Rio Chingual-La Sofia et Pallatanga qui limitent respectivement au Nord et au Sud des failles inverses N-S du relais compressif de la vallée interandine (failles de Quito et de Latacunga. L’étude des mécanismes au foyer superficiels des Andes équatoriennes nous a permis de calculer une vitesse de raccourcissement crustal de 4.6 mm/a selon une direction N92°E et d’estimer des temps de récurrence et des périodes de retour. Un séisme de Mw = 5 pourrait se produire tous les 0.5 an, de Mw = 6 tous les 4.5 ans, de Mw = 7 tous les 45.4 ans. De même, sur une période de temps de 33 ans, 66 séismes de Mw=5 peuvent être attendus, 7 séismes de Mw=6 et 1 séisme de Mw=7. Enfin, nous avons estimé pour l’ensemble des sources sismogènes de la région andine des magnitudes maximales probables et des temps de récurrence. Un séisme de magnitude 7 à 7.5 peut se produire sur la faille du Rio Chingual tous les 400±440 ans et de magnitude 6.7 à 7.2 tous les 380±320 ans sur la faille de Pallatanga.

Associations between the sense of humor and survival in relation to specific diseases has so far never been studied. We conducted a 15-year follow-up study of 53,556 participants in the population-based Nord-Trøndelag Health Study, Norway. Cognitive, social, and affective components of the sense of humor were obtained, and associations with all-cause mortality, mortality due to cardiovascular diseases (CVD), infections, cancer, and chronic obstructive pulmonary diseases were estimated by hazard ratios (HRs). After multivariate adjustments, high scores on the cognitive component of the sense of humor were significantly associated with lower all-cause mortality in women (HR = 0.52, 95% confidence interval [CI] = 0.33-0.81), but not in men (HR = 0.88, 95% CI = 0.59-1.32). Mortality due to CVD was significantly lower in women with high scores on the cognitive component (HR = 0.27, 95% CI = 0.15-0.47), and so was mortality due to infections both in men (HR = 0.26, 95% CI = 0.09-0.74) and women (HR = 0.17, 95% CI = 0.04-0.76). The social and affective components of the sense of humor were not associated with mortality. In the total population, the positive association between the cognitive component of sense of humor and survival was present until the age of 85 years. The cognitive component of the sense of humor is positively associated with survival from mortality related to CVD and infections in women and with infection-related mortality in men. The findings indicate that sense of humor is a health-protecting cognitive coping resource.

Full Text Available The article examines the relationship between neighbourhood social capital and two health outcomes: selfrated health and depression. A total of 42,571 individuals aged 30–67 years participated in a cross-sectional total population health study in Nord-Trøndelag in 1995–1997 (HUNT II and were investigated using multilevel modelling. Aims were, first, to investigate potential area effects after accounting for the characteristics of individuals in the neighbourhoods (N = 155, and, second, to explore the relationships between contextual social capital (the level of trust at the neighbourhood level and the level of local organizational activity and the two health measures. Models with stepwise inclusion of individual level factors attenuated the ward level variance for both self-rated health (PCV: 41% and depression (PCV: 43%. The inclusion of the two contextual social capital items attenuated the ward level variance for both self-rated health and depression, however to varying degrees. At the individual level, contextual social capital was associated with both self-rated health and depression. Individuals living in wards with a low level of trust experienced an increased risk of 1.36 (95% CI: 1.13-1.63 for poor self-rated health compared to individuals in wards with a high level of trust. For depression, this effect was even stronger (OR 1.52, 1.23-1.87. The associations with the level of organizational activity were inconsistent and weaker for both health outcomes. It was concluded that geographical variations in self-rated health and depression are largely due to the socioeconomic characteristics of individuals. Nevertheless, contextual social capital, expressed as the level of trust, was found to be associated with depression and self-rated health at individual level.

Programs for a variety of microprocessors (including Intel 8080; Motorola 6800 and 6809 and 68000; and Texas Instruments 9900) can be prepared on different host computers (such as IBM 370, CDC 6000, and Nord 10) using portable programs developed at CERN. The range of cross software consists of: an assembler for each target microprocessor, a single linkage editor, a single object module librarian, and a variety of pre-loaders which convert object modules from CERN's format (CUFOM) into manufacturers' formats. The programs are written in BCPL and PASCAL, programming languages which are available on a wide range of computers. (orig.)

The relationship between health promoting resources and work participation in a sample reporting musculoskeletal pain from the Nord-Trøndelag Health Study, HUNT 3, Norway

Science.gov (United States)

2013-01-01

Background Musculoskeletal pain (MSP) is one of the most frequent causes of sick leave from work, and is a common and potentially disabling condition. This study is based on the salutogenic perspective and investigates the relationship between personal, social, and functional health resources and work participation in a population reporting MSP. Method Analysis was performed on cross sectional data from the Nord-Trøndelag Health Study, HUNT 3, in Norway. The sample of n= 6702 was extracted from HUNT 3, including a total of N= 50807 participants. Self-reported health (SRH) and, personal, social, and functional resources were assessed by a questionnaire. Reported sick leave was collected by interview at the point of time when the data were collected, from October 2006 until June 2008. Results Logistic regression analysis demonstrated statistically significant differences between the work group and sick leave group in self-rated health, work support, work control, work load, and feeling strong, and the model predicted 68% of the cases correctly. Females had a lower statistically significant probability (B= −.53) to be in the work group then men when suffering from MSP, with odds of 41%. Conclusion There was a statistically significant relationship between health promoting resources such as SRH, feeling strong, absence of neuroticism, work load, work control, and work participation in MSP population.

Full Text Available Abstract Background Physical inactivity is associated with several diseases, but studies evaluating the association between chronic musculoskeletal complaints (MSCs and physical exercise have shown conflicting results. The aim of this large-scale prospective population-based study was to investigate the association between self-reported physical exercise at baseline and the prevalence of chronic musculoskeletal complaints (MSCs 11 years later. Methods The results are based upon two consecutive public health studies conducted within the county of Nord-Trøndelag, Norway (The HUNT studies. A total of 39,520 (83% out of 47,556 adults who participated in HUNT 1 and HUNT 2 responded to questions about physical exercise at baseline in 1984–86, and to questions about musculoskeletal complaints 11 years later (1995–97. Chronic MSCs was defined as MSCs ≥ 3 months during the past year, and chronic widespread MSCs such as pain ≥ 15 days during the last month from the axial region, above the waist, and below the waist. Associations were assessed using multiple logistic regression, estimating prevalence odds ratio (OR with 95% confidence intervals (CIs. All the final analyses were adjusted for age, gender, body mass index, smoking and education level. Results At follow-up 20,223 (51% reported chronic MSCs, and among these 2,318 (5.9% reported chronic widespread MSCs. Individuals who exercised at baseline were less likely to report chronic MSCs 11 years later (OR 0.91, 95% CI 0.85–0.97 than inactive persons. Among individuals who exercised more than three times per week, chronic widespread MSCs were 28% less common (OR 0.72, 95% CI 0.59–0.88 compared to inactive individuals. Conclusion In this large-scale population-based study, physical exercise was associated with lower prevalence of chronic MSCs, in particular chronic widespread MSCs. Future studies should try to clarify whether chronic MSCs are a cause or a consequence of inactivity.

Assessing gas transit risks: Russia vs. the EU

International Nuclear Information System (INIS)

Le Coq, Chloé; Paltseva, Elena

2012-01-01

This paper proposes a Transit Risk Index (TRI) designed to assess the riskiness of pipeline gas imports and to study the effect of introducing new gas routes. TRI controls for gas dependency, transit route diversification, political risks of transit, pipeline rupture probability, and the balance of power between supplying and consuming countries along the transit route. Evaluating TRI for the EU-Russia gas trade, we show that the introduction of the Nord Stream pipeline would further widen already large disparities in gas risk exposure across the EU Member States. The gas risk exposure of the Member States served by Nord Stream would decline. In contrast, EU countries not connected to Nord Stream, but sharing other Russian gas transit routes with the Nord Stream countries, would face greater gas risk exposure. We discuss the implications of our analysis for the design of the common energy policy in the EU.

ALICE - A computer program for nuclear data acquisition

International Nuclear Information System (INIS)

Skaali, T.B.

1981-02-01

This manual contains the users guide and the program documentation for the ALICE data acquisition system. The ALICE Users Guide, which is contained in part 1 of the manual, can be read independently of the program documentation in part 2. The ALICE program is written in the interpretive language NODAL. Due to the inherent slow execution speed of interpreted code time-consuming tasks such as non-linear least squares peak fitting cannot be implemented. On the other hand the special features of the NODAL language have made possible facilities in ALICE which hardly could have been realized by, e.g. a FORTRAN program. The complete system can be divided in two parts, i) the ALICE program written in NODAL, and ii) a data acquisition package which logically represents an extension of the SINTRAN III operating system. The system is thus portable to other NORD- 10/100 installations provided that the floating hardware is 48 bits. (Auth.)

Common Nordic Retail Market. Organisation of the further work

Energy Technology Data Exchange (ETDEWEB)

2010-12-15

For several years NordREG has been working to promote and facilitate a common Nordic end user market. Given the political support that was expressed at the meeting of the Nordic energy ministers in the autumn of 2009, the work has become even more concrete. It should also be noted that the energy ministers expressed their support for the NordREGs implementation plan for a common Nordic retail market at their yearly meeting on the 25th of October 2010. With this organization document, NordREG define the organization of the future work and the governance rules of the whole process. The document shows which bodies needs to be established, what their roles are and how the decision-making and the consultation of stakeholders will be organized. As the document shows, the need for contributed efforts from all stakeholders will be vital in the coming years in order to make a reality of the plans for creating a common Nordic end user market. The organization document has been prepared by the NordREG Retail and Distribution Working Group. Nordenergi and Nordic TSOs have had an opportunity to comment the document before it was finalized. NordREG appreciates all the comments and has taken them into consideration before finalizing the document

Physical activity in leisure time seems to reduce the risk of low back pain, but it is not known whether occupational activity, as recorded in a representative working population, produces a higher or lower risk. To study associations between physical activity level at work and risk of chronic low back pain. Associations were examined in a Norwegian prospective study using data from the HUNT2 and HUNT3 surveys carried out in the whole county of Nord-Trøndelag. Participants were 7580 women and 7335 men who supplied information about physical activity level at work. Levels considered were sedentary work, work involving walking but no heavy lifting, work involving walking and heavy lifting, and particularly strenuous physical work. Nobody in the cohort was affected by chronic low back pain at baseline. After 11 years, participants reported whether they suffered from chronic low back pain. Generalized linear modelling with adjustment for potential confounders was applied to assess associations with risk factors. In age-adjusted analyses both women and men showed statistically significant associations between physical activity at work and risk of chronic low back pain, suggesting positive relationships. For particularly strenuous physical work the relative risk of chronic low back pain was 1.30 (95% CI: 1.00-1.71) in women and 1.36 (95% CI 1.17-1.59) in men, compared to sedentary work. Women still showed a general association with activity level after adjustment for education, leisure time physical activity, BMI, smoking and occupational category. In men, the higher risk was only maintained for particularly strenuous work. In this cohort, women had a higher risk of chronic low back pain with work involving walking and heavy lifting or particularly strenuous work, compared to sedentary work. Men participating in particularly strenuous work also experienced a higher risk of chronic low back pain.

Full Text Available Cet article explore les différentes fonctions des peintures murales en Irlande du Nord et au Pays basque. Il montre comment les peintures murales, particulièrement visibles, ont la capacité de diffuser un message en permanence. En ce sens, comme les avancées conceptuelles sur la question de l’identification nationale permettent de le définir, elles constituent un support des processus de définition et de redéfinition des références identificatoires, et elles permettent de maintenir les dynamiques de polarisation communautaire comme éléments dominants de la structuration de l’espace public. Il n’y a que peu voire pas d’espace pour d’autres représentations de la vie sociale. Les peintures murales sont un outil de légitimation de la lutte, ce qui peut provoquer adhésion, soutien, ou mobilisation. Elles actualisent et élargissent le champ des références disponibles pour les processus d’identification, et rendent ce corpus de références toujours accessible à la population. Ainsi, elles participent activement à la dynamique du conflit.This article explores the several functions of mural paintings in Northern Ireland and in the Basque Country. It shows how the murals (which are particularly visible have the capacity to broadcast a message on a permanent basis. Recent conceptual progress on the question of national identification allows defining them as a basis for processes of definitions and re-definitions of identity references; they are also a means of keeping community polarization dynamics as the dominant elements in structuring the public space. Little or no space is left for other representations of social life. Murals are a tool for legitimising the struggle, which can stimulate adhesion, support or mobilization. They update and widen the field of references available for the identification processes, and make this corpus of references ready for use at any time for the population. Thus, they play an active part

This paper compiles all the measured chemical warfare agent (CWA) concentrations found in relation to the Nord Stream pipeline work in Danish waters for the past 5 years. Sediment and biota sampling were performed along the pipeline route in four campaigns, prior to (in 2008 and 2010), during (in 2011) and after (in 2012) the construction work. No parent CWAs were detected in the sediments. Patchy residues of CWA degradation products of Adamsite, Clark I, phenyldichloroarsine, trichloroarsine and Lewisite II, were detected in a total of 29 of the 391 sediment samples collected and analyzed the past 5 years. The cumulative fish community risk quotient for the different locations, calculated as a sum of background and added risk, ranged between 0 and 0.017 suggesting a negligible acute CWA risk toward the fish community. The added risk from sediment disturbance in relation to construction of the pipelines represents less than 2% of the total risk in the areas with the highest calculated risk. The analyses of benthic infauna corroborate the finding of CWA related low risk across the years. There was no significant difference in CWA risk before (2008) and after the pipeline construction (2012). Copyright © 2014 Elsevier B.V. All rights reserved.

Gender differences in the prevalence of symptoms of anxiety and depression during adolescence are well documented. However, little attention has been given to differences in subjective well-being, self-esteem and psychosocial functioning between boys and girls with symptoms of anxiety and depression. The aim of this study was to investigate gender differences in the associations between such symptoms and subjective well-being, self-esteem, school functioning and social relations in adolescents. Data were taken from a major population-based Norwegian study, the Nord-Trøndelag Health study (HUNT), in which 8984 (91% of all invited) adolescents, aged 13-19 years, completed an extensive self-report questionnaire. Although prevalence rates of symptoms of anxiety and depression were higher in girls than in boys, a significant interaction between gender and symptoms of anxiety and depression was found in respect of each of the following outcome variables: subjective well-being, self-esteem, academic problems, frequency of meeting friends and the feeling of not having enough friends. These interactions indicate that the associations between symptoms of anxiety and depression and lower subjective well-being and self-esteem, more academic problems in school and lower social functioning were stronger for boys than for girls. Our findings may contribute to an earlier assessment and more efficient treatment of male adolescent anxiety and depression. © 2011 The Authors.

Pb concentrations and isotope ratios of soil O and C horizons in Nord-Trøndelag, central Norway: Anthropogenic or natural sources?

International Nuclear Information System (INIS)

Reimann, C.; Fabian, K.; Flem, B.; Schilling, J.; Roberts, D.; Englmaier, P.

2016-01-01

Soil O and C horizon samples (N = 752) were collected at a sample density of 1 site/36 km"2 in Nord-Trøndelag and parts of Sør-Trøndelag (c. 25,000 km"2), and analysed for Pb and three of the four naturally occurring Pb isotopes ("2"0"6Pb, "2"0"7Pb and "2"0"8Pb) in a HNO_3/HCl extraction. Soil O and C horizons are decoupled in terms of both Pb concentrations and Pb isotope ratios. In the soil C horizon the Grong-Olden Culmination, a continuous exposure of the Precambrian crystalline basement across the general grain of the Caledonian orogen, is marked by a distinct "2"0"6Pb/"2"0"7Pb isotope ratio anomaly. No clear regional or even local patterns are detected when mapping the Pb isotope ratios in the soil O horizon samples. Variation in the isotope ratios declines significantly from the soil C to the O horizon. On average, Pb concentrations in the O horizon are four times higher and the "2"0"6Pb/"2"0"7Pb isotope ratio is shifted towards a median of 1.15 in comparison to 1.27 in the C horizon. It is demonstrated that natural processes like weathering in combination with plant uptake need to be taken into account in order to distinguish anthropogenic input from natural influences on Pb concentration and the "2"0"6Pb/"2"0"7Pb isotope ratio in the soil O horizon. - Highlights: • Lead concentrations are on average higher by a factor of 4 in the soil O than in the C horizon. • The "2"0"6Pb/"2"0"7Pb isotope ratio is considerably lower in the soil O than in the C horizon. • The observed shifts are in conflict with exclusive anthropogenic input of Pb. • The hypothesis of natural Pb-isotope invariance can not be hold.

Peak load arrangements : Assessment of Nordel guidelines

Energy Technology Data Exchange (ETDEWEB)

2009-07-01

Two Nordic countries, Sweden and Finland, have legislation that empowers the TSO to acquire designated peak load resources to mitigate the risk for shortage situations during the winter. In Denmark, the system operator procures resources to maintain a satisfactory level of security of supply. In Norway the TSO has set up a Regulation Power Option Market (RKOM) to secure a satisfactory level of operational reserves at all times, also in winter with high load demand. Only the arrangements in Finland and Sweden fall under the heading of Peak Load Arrangements defined in Nordel Guidelines. NordREG has been invited by the Electricity Market Group (EMG) to evaluate Nordel's proposal for 'Guidelines for transitional Peak Load Arrangements'. The EMG has also financed a study made by EC Group to support NordREG in the evaluation of the proposal. The study has been taken into account in NordREG's evaluation. In parallel to the EMG task, the Swedish regulator, the Energy Markets Inspectorate, has been given the task by the Swedish government to investigate a long term solution of the peak load issue. The Swedish and Finnish TSOs have together with Nord Pool Spot worked on finding a harmonized solution for activation of the peak load reserves in the market. An agreement accepted by the relevant authorities was reached in early January 2009, and the arrangement has been implemented since 19th January 2009. NordREG views that the proposed Nordel guidelines have served as a starting point for the presently agreed procedure. However, NordREG does not see any need to further develop the Nordel guidelines for peak load arrangements. NordREG agrees with Nordel that the market should be designed to solve peak load problems through proper incentives to market players. NordREG presumes that the relevant authorities in each country will take decisions on the need for any peak load arrangement to ensure security of supply. NordREG proposes that such decisions should be

Popular Literature Discourses in Athenian Suburbia: The Northern Suburbs Les banlieues nord d’Athènes dans les discours littéraires populaires

Directory of Open Access Journals (Sweden)

Irene Theodoropoulou

2010-01-01

Full Text Available Suburbia, home to a life-style many people aspire to, could be seen as a marriage between urban and countryside life, and, as such, it should be seen as a vital arena for interdisciplinary research on the urban-rural paradigm. This paper explores the ways whereby discourses on what is stereotypically seen as posh northern Athens suburban culture (Voreia Proastia are represented in popular literature. The main argument is that Voreia Proastia suburban culture could be seen as positioned on an urban/countryside continuum. This is grounded on the simple reason that, both at the speech level and in terms of lifestyle, it encompasses features of urban and rural worlds, the former associated with the “new-poor” or “elegant poverty” people, the latter with the “new-rich”.Les zones périurbaines donnent lieu à un train de vie auquel aspirent de nombreuses personnes, étant donné qu’elles semblent marier la vie urbaine et la vie rurale. De ce fait, ces zones constituent un domaine essentiel pour la recherche interdisciplinaire sur le paradigme urbain-rural. Cet article cherche à examiner les manières selon lesquelles les discours associés aux banlieues nord d’Athènes (Voreia Proastia, considérées de manière stéréotypée comme chics, sont repris par la littérature populaire. A travers l’analyse de cette appropriation, nous tentons de comprendre leur signification sociale. L’argument principal avancé ici est que la culture suburbaine de Voreia Proastia se positionne sur un continuum entre l’urbain et le rural pour la simple raison qu’au niveau des pratiques langagières et des styles de vie, elle englobe à la fois des caractéristiques du monde urbain, associé aux « nouveaux pauvres » ou à la « pauvreté élégante », et du monde rural, associé aux « nouveaux riches ».

Full Text Available A program for development and evaluation of xanthan for use in enhanced oil recovery projects in the North Sea has been performed. Xanthan was produced using different fermentation conditions. Rheological measurements and filterability tests have been done. Xanthan products, which readily dissolve in sea water and give high viscosity and low aggregation have been produced. The fermentation process used for this type of product was scaled up from 10 litres to 20,000 litres production volume without significant changes in polymer solution properties. Un programme de développement et d'évaluation du xanthane pour utilisation dans les projets de récupération assistée des hydrocarbures en mer du Nord a été réalisé. Le xanthane est obtenu par différents procédés de fermentation. On a effectué des mesures rhéologiques et des essais de filtrabilité. Les produits à base de xanthane se dissolvent facilement dans l'eau de mer, ils donnent une forte viscosité et une faible agrégation. Avec le procédé de fermentation utilisé pour ce type de produit, on a pu faire passer la production de 10 litres à 20000 litres sans modification notable des propriétés de la solution de polymère.

Event sizes and data rates at the CERN anti p p collider compose a formidable environment for a high level trigger. A system using three 168/E processors for experiment UA1 real-time event selection is described. With 168/E data memory expanded to 512K bytes, each processor holds a complete event allowing a FORTRAN trigger algorithm access to data from the entire detector. A smart CAMAC interface reads five Remus branches in parallel transferring one word to the target processor every 0.5 μs. The NORD host computer can simultaneously read an accepted event from another processor

Comparisons between physics-based, engineering, and statistical learning models for outdoor sound propagation.

Science.gov (United States)

Hart, Carl R; Reznicek, Nathan J; Wilson, D Keith; Pettit, Chris L; Nykaza, Edward T

2016-05-01

Many outdoor sound propagation models exist, ranging from highly complex physics-based simulations to simplified engineering calculations, and more recently, highly flexible statistical learning methods. Several engineering and statistical learning models are evaluated by using a particular physics-based model, namely, a Crank-Nicholson parabolic equation (CNPE), as a benchmark. Narrowband transmission loss values predicted with the CNPE, based upon a simulated data set of meteorological, boundary, and source conditions, act as simulated observations. In the simulated data set sound propagation conditions span from downward refracting to upward refracting, for acoustically hard and soft boundaries, and low frequencies. Engineering models used in the comparisons include the ISO 9613-2 method, Harmonoise, and Nord2000 propagation models. Statistical learning methods used in the comparisons include bagged decision tree regression, random forest regression, boosting regression, and artificial neural network models. Computed skill scores are relative to sound propagation in a homogeneous atmosphere over a rigid ground. Overall skill scores for the engineering noise models are 0.6%, -7.1%, and 83.8% for the ISO 9613-2, Harmonoise, and Nord2000 models, respectively. Overall skill scores for the statistical learning models are 99.5%, 99.5%, 99.6%, and 99.6% for bagged decision tree, random forest, boosting, and artificial neural network regression models, respectively.

Analysis of the Risk of Bankruptcy of Tomato Processing Companies Operating in the Inter-Regional Interprofessional Organization “OI Pomodoro da Industria Nord Italia”

Directory of Open Access Journals (Sweden)

Mattia Iotti

2018-03-01

Full Text Available The tomato sector is a major area of agricultural activity in Italy; tomato production and processing characterize different Italian regions; in particular, there are two production districts, one in southern Italy and one in northern Italy, in the Po Valley. In recent years, processing firms have encountered increasing difficulties, due both to an increase in raw material costs and market difficulties. Tomato processing firms are often characterized by significant investment in fixed assets and working capital, with an ensuing increase in equity or debt financing, which increases the risk of bankruptcy, as has happened to many firms in the sector in recent years. Therefore, the aim of this research was to analyze the financial sustainability of tomato processing firms by applying financial ratios. To achieve this goal, this research focused on the annual data of a sample of 17 tomato processing firms operating in the Inter-regional Interprofessional Organization, “OI Pomodoro da Industria Nord Italia”. The firms were divided into still-active (not-distressed and failed (distressed firms, with the aim of analyzing the differences between the financial data and management practices of the two groups. The data suggest that larger firms, with an adequate financial structure, have been able to withstand the tomato market crisis in recent years, whereas distressed firms are on average smaller and suffer from higher recourse to debt capital and lower profit margins than not-distressed firms. This research could be applied by entrepreneurs, managers, bankers and public operators to define good management practices that should be achieved and measured with financial ratios, even as a means of reducing the risk of distress for firms operating in the tomato sector. This research highlights that financial ratios could be usefully applied for predicting the continuity of activity and therefore the sustainability of the management cycle, including its

Poland wants to thwart Russian gas

International Nuclear Information System (INIS)

Barbaux, Aurelie

2013-01-01

The Polish authorities are doing everything in their power to block Nord Stream 2, the Russian natural gas pipeline project that will double (by 2019) Nord Stream 1 through the Baltic Sea. Gazprom's Nord Stream 2 (in which European companies such as Engie (France), Uniper and Wintershall (Germany), OMV (Austria) and Shell are involved) will poses a risk, according to Poland, to the gas supply of central European countries (and notably Ukraine). Poland also intends to stop all its gas imports from Russia after 2022 (end of the Yamal contract): the country is therefore developing its capacity to increase its own natural gas production and has just inaugurated a liquefied natural gas terminal on the Baltic Sea. A gas pipeline is also in project, that will link Norway to Poland. For power generation, the nuclear energy option is also studied

Valiev, Kamil' A

2005-01-01

This review outlines the principles of operation of quantum computers and their elements. The theory of ideal computers that do not interact with the environment and are immune to quantum decohering processes is presented. Decohering processes in quantum computers are investigated. The review considers methods for correcting quantum computing errors arising from the decoherence of the state of the quantum computer, as well as possible methods for the suppression of the decohering processes. A brief enumeration of proposed quantum computer realizations concludes the review. (reviews of topical problems)

Quantum Computing for Computer Architects

CERN Document Server

2011-01-01

Quantum computers can (in theory) solve certain problems far faster than a classical computer running any known classical algorithm. While existing technologies for building quantum computers are in their infancy, it is not too early to consider their scalability and reliability in the context of the design of large-scale quantum computers. To architect such systems, one must understand what it takes to design and model a balanced, fault-tolerant quantum computer architecture. The goal of this lecture is to provide architectural abstractions for the design of a quantum computer and to explore

Specialized computer architectures for computational aerodynamics

Science.gov (United States)

Stevenson, D. K.

1978-01-01

In recent years, computational fluid dynamics has made significant progress in modelling aerodynamic phenomena. Currently, one of the major barriers to future development lies in the compute-intensive nature of the numerical formulations and the relative high cost of performing these computations on commercially available general purpose computers, a cost high with respect to dollar expenditure and/or elapsed time. Today's computing technology will support a program designed to create specialized computing facilities to be dedicated to the important problems of computational aerodynamics. One of the still unresolved questions is the organization of the computing components in such a facility. The characteristics of fluid dynamic problems which will have significant impact on the choice of computer architecture for a specialized facility are reviewed.

Neural computation and the computational theory of cognition.

Science.gov (United States)

Piccinini, Gualtiero; Bahar, Sonya

2013-04-01

We begin by distinguishing computationalism from a number of other theses that are sometimes conflated with it. We also distinguish between several important kinds of computation: computation in a generic sense, digital computation, and analog computation. Then, we defend a weak version of computationalism-neural processes are computations in the generic sense. After that, we reject on empirical grounds the common assimilation of neural computation to either analog or digital computation, concluding that neural computation is sui generis. Analog computation requires continuous signals; digital computation requires strings of digits. But current neuroscientific evidence indicates that typical neural signals, such as spike trains, are graded like continuous signals but are constituted by discrete functional elements (spikes); thus, typical neural signals are neither continuous signals nor strings of digits. It follows that neural computation is sui generis. Finally, we highlight three important consequences of a proper understanding of neural computation for the theory of cognition. First, understanding neural computation requires a specially designed mathematical theory (or theories) rather than the mathematical theories of analog or digital computation. Second, several popular views about neural computation turn out to be incorrect. Third, computational theories of cognition that rely on non-neural notions of computation ought to be replaced or reinterpreted in terms of neural computation.

Nordic market report 2009 : Development in the Nordic electricity market

Energy Technology Data Exchange (ETDEWEB)

2009-07-01

The Nordic region is characterized by a unique mix of generation sources where the high share of hydropower, representing virtually all of the Norwegian and nearly half of the Swedish generation capacity, has a great influence on the market. The level of precipitation is thus vital when calculating and analysing potential generation levels. In addition, the Nordic region has significantly colder winters than any other European country, influencing the consumption as many households are electrically heated. In 2008 the overall electricity consumption in the Nordic region was slightly higher - 1.6 per cent - than in 2007. During periods of peak consumption the Nordic power system proved sufficient to ensure security of supply without restrictions on consumption. The Nordic region operates almost entirely as one synchronous power system through transmission grid. The continuous reinforcement of the Nordic transmission grid has enabled an increased security of supply as well as a more efficient use of the generation capacity. Increasing cross border power flows strain the transmission lines and increases the demand for transmission capacity. Possible congestions occurring between the Nord Pool bidding areas are handled through market splitting, while internal congestions in general are handled through counter trade or by reducing interconnector capacity at the bidding area borders. The Nordic wholesale power market is a well functioning electricity market. Trade at Nord Pool has increased steadily since it was established in 1993. Although trading at Nord Pool Spot is voluntary, significantly more physical power is now traded on the power exchange than bilaterally - from 42 per cent of total Nordic consumption in 2004 to 76 per cent in 2008. During 2008 average spot prices at Nord Pool were considerably higher (approximately 60 per cent) than prices in 2007.

Full Text Available L'étude pétrographique et minéralogique d'un réservoir jurassique de mer du Nord permet de mettre en évidence trois stades diagénétiques successifs qui se manifestent chacun par des évolutions minéralogiques spécifiques. Le dernier stade est contemporain de la mise en place de l'huile et des eaux salées. Celles-ci provoquent la néogenèse d'illite et l'illitisation de la dickite élaborée pendant l'enfouissement du réservoir. Des datations absolues par la méthode K/A effectuées sur ces illites donnent un âge lutétien moyen pour la mise en place de l'huile et des eaux salées. A petrographic and mineralogical study of a Jurassic reservoir in the North Sea reveals three successive diagenetic stages, each having a specific mineralogical evolution. The last stage is contemporary with the implantation of oil and salt water. This water has coused the neogenesis of illite and the illitization of the dickite that formed during the burial of the reservoir. Absolute dating of these illites by the K/A method reveals a Middle Lutetian age for the implantation of oil and salt water.

Market power in the Nordic electricity wholesale market: A survey of the empirical evidence

International Nuclear Information System (INIS)

Fridolfsson, Sven-Olof; Tangeras, Thomas P.

2009-01-01

We review the recent empirical research assessing market power on the Nordic wholesale market for electricity, Nord Pool. The studies find no evidence of systematic exploitation of system level market power on Nord Pool. Local market power arising from transmission constraints seems to be more problematic in some price areas across the Nordic countries. Market power can manifest itself in a number of ways that have so far escaped empirical scrutiny. We discuss investment incentives, vertical integration and buyer power, as well as withholding of base-load (nuclear) capacity.

Bias with regard to participation in epidemiological studies can have a large impact on the generalizability of results. Our aim was to investigate the direction and magnitude of potential bias by comparing health-related factors among participants and non-participants in a MRI-study based on HUNT, a large Norwegian health survey. Of 14,033 individuals aged 50–65, who had participated in all three large public health surveys within the Norwegian county of Nord-Trøndelag (HUNT 1, 2 and 3), 1,560 who lived within 45 minutes of travel from the city of Levanger were invited to a MRI study (MRI-HUNT). The sample of participants in MRI-HUNT (n = 1,006) were compared with those who were invited but did not participate (n = 554) and with those who were eligible but not invited (n = 12,473), using univariate analyses and logistic regression analyses adjusting for age and education level. Self-reported health did not differ between the three groups, but participants had a higher education level and were somewhat younger than the two other groups. In the adjusted multivariate analyses, obesity was consistently less prevalent among participants. Significant differences in blood pressure and cholesterol were also found. This is the first large population-based study comparing participants and non-participants in an MRI study with regard to general health. The groups were not widely different, but participants had a higher level of education, and were less likely to be obese and have hypertension, and were slightly younger than non-participants. The observed differences between participants and non-invited individuals are probably partly explained by the inclusion criterion that participants had to live within 45 minutes of transport to where the MRI examination took place. One will expect that the participants have somewhat less brain morphological changes related to cardiovascular risk factors than the general population. Such consequences underline the crucial importance

Metal-semiconductors (MSs) or Schottky barrier diodes (SBDs) have a significant potential in the integrated device technology. In the present paper, electrical characterization of Ag/InGaN/n-Si Schottky diode have been systematically carried out by simple Thermionic method (TE) and Norde function based on the I-V characteristics. Ag ohmic and schottky contacts are deposited on InGaN/n-Si film by thermal evaporation technique under a vacuum pressure of 1×10{sup −5} mbar. Ideality factor, barrier height and series resistance values of this diode are determined from I-V curve. These parameters are calculated by TE and Norde methods and findings are given in a comparetive manner. The results show the consistency for both method and also good agreement with other results obtained in the literature. The value of ideality factor and barrier height have been determined to be 2.84 and 0.78 eV at room temperature using simple TE method. The value of barrier height obtained with Norde method is calculated as 0.79 eV.

Privacy-Preserving Computation with Trusted Computing via Scramble-then-Compute

Directory of Open Access Journals (Sweden)

Dang Hung

2017-07-01

Full Text Available We consider privacy-preserving computation of big data using trusted computing primitives with limited private memory. Simply ensuring that the data remains encrypted outside the trusted computing environment is insufficient to preserve data privacy, for data movement observed during computation could leak information. While it is possible to thwart such leakage using generic solution such as ORAM [42], designing efficient privacy-preserving algorithms is challenging. Besides computation efficiency, it is critical to keep trusted code bases lean, for large ones are unwieldy to vet and verify. In this paper, we advocate a simple approach wherein many basic algorithms (e.g., sorting can be made privacy-preserving by adding a step that securely scrambles the data before feeding it to the original algorithms. We call this approach Scramble-then-Compute (StC, and give a sufficient condition whereby existing external memory algorithms can be made privacy-preserving via StC. This approach facilitates code-reuse, and its simplicity contributes to a smaller trusted code base. It is also general, allowing algorithm designers to leverage an extensive body of known efficient algorithms for better performance. Our experiments show that StC could offer up to 4.1× speedups over known, application-specific alternatives.

Computer scientist looks at reliability computations

1975-01-01

Results from the theory of computational complexity are applied to reliability computations on fault trees and networks. A well known class of problems which almost certainly have no fast solution algorithms is presented. It is shown that even approximately computing the reliability of many systems is difficult enough to be in this class. In the face of this result, which indicates that for general systems the computation time will be exponential in the size of the system, decomposition techniques which can greatly reduce the effective size of a wide variety of realistic systems are explored

Ownership structure and market power in the nordic power market

International Nuclear Information System (INIS)

Amundsen, E.S.; Bergman, L.

1999-01-01

The opening of Nord Pool in 1996 seriously constrained the power companies' ability to exercise market power within their national borders. Currently there is an integration process going on among the power companies in the Nord Pool area. It manifest itself in terms of take-over and reciprocal acquisition of shares in the power companies - nationally and abroad. This process may undo what the introduction of the common power market achieved in curtailing market power. The aim of this paper is to investigate the effects on market power of increased cross- ownership in the Nordic power market. (au)

Heterotic computing: exploiting hybrid computational devices.

Kendon, Viv; Sebald, Angelika; Stepney, Susan

2015-07-28

Current computational theory deals almost exclusively with single models: classical, neural, analogue, quantum, etc. In practice, researchers use ad hoc combinations, realizing only recently that they can be fundamentally more powerful than the individual parts. A Theo Murphy meeting brought together theorists and practitioners of various types of computing, to engage in combining the individual strengths to produce powerful new heterotic devices. 'Heterotic computing' is defined as a combination of two or more computational systems such that they provide an advantage over either substrate used separately. This post-meeting collection of articles provides a wide-ranging survey of the state of the art in diverse computational paradigms, together with reflections on their future combination into powerful and practical applications. © 2015 The Author(s) Published by the Royal Society.

Overview In autumn the main focus was to process and handle CRAFT data and to perform the Summer08 MC production. The operational aspects were well covered by regular Computing Shifts, experts on duty and Computing Run Coordination. At the Computing Resource Board (CRB) in October a model to account for service work at Tier 2s was approved. The computing resources for 2009 were reviewed for presentation at the C-RRB. The quarterly resource monitoring is continuing. Facilities/Infrastructure operations Operations during CRAFT data taking ran fine. This proved to be a very valuable experience for T0 workflows and operations. The transfers of custodial data to most T1s went smoothly. A first round of reprocessing started at the Tier-1 centers end of November; it will take about two weeks. The Computing Shifts procedure was tested full scale during this period and proved to be very efficient: 30 Computing Shifts Persons (CSP) and 10 Computing Resources Coordinators (CRC).

2013-01-01

Full Text Available Cloud computing represents a specific networking, in which a computer program simulates the operation of one or more server computers. In terms of copyright, all technological processes that take place within the cloud computing are covered by the notion of copying computer programs, and exclusive right of reproduction. However, this right suffers some limitations in order to allow normal use of computer program by users. Based on the fact that the cloud computing is virtualized network, the issue of normal use of the computer program requires to put all aspects of the permitted copying into the context of a specific computing environment and specific processes within the cloud. In this sense, the paper pointed out that the user of a computer program in cloud computing, needs to obtain the consent of the right holder for any act which he undertakes using the program. In other words, the copyright in the cloud computing is a full scale, and thus the freedom of contract (in the case of this particular restriction as well.

I'll discuss how computational complexity---the study of what can and can't be feasibly computed---has been interacting with physics in interesting and unexpected ways. I'll first give a crash course about computer science's P vs. NP problem, as well as about the capabilities and limits of quantum computers. I'll then touch on speculative models of computation that would go even beyond quantum computers, using (for example) hypothetical nonlinearities in the Schrodinger equation. Finally, I'll discuss BosonSampling ---a proposal for a simple form of quantum computing, which nevertheless seems intractable to simulate using a classical computer---as well as the role of computational complexity in the black hole information puzzle.

This book is a comprehensive introduction to analog computing. As most textbooks about this powerful computing paradigm date back to the 1960s and 1970s, it fills a void and forges a bridge from the early days of analog computing to future applications. The idea of analog computing is not new. In fact, this computing paradigm is nearly forgotten, although it offers a path to both high-speed and low-power computing, which are in even more demand now than they were back in the heyday of electronic analog computers.

Kia, Behnam; Murali, K.; Jahed Motlagh, Mohammad-Reza; Sinha, Sudeshna; Ditto, William L.

Nonlinearity and chaos can illustrate numerous behaviors and patterns, and one can select different patterns from this rich library of patterns. In this paper we focus on synthetic computing, a field that engineers and synthesizes nonlinear systems to obtain computation. We explain the importance of nonlinearity, and describe how nonlinear systems can be engineered to perform computation. More specifically, we provide an overview of chaos computing, a field that manually programs chaotic systems to build different types of digital functions. Also we briefly describe logical stochastic resonance (LSR), and then extend the approach of LSR to realize combinational digital logic systems via suitable concatenation of existing logical stochastic resonance blocks. Finally we demonstrate how a chaotic system can be engineered and mated with different machine learning techniques, such as artificial neural networks, random searching, and genetic algorithm, to design different autonomous systems that can adapt and respond to environmental conditions.

The combination of computer system technology and numerical modeling have advanced to the point that computational aerodynamics has emerged as an essential element in aerospace vehicle design methodology. To provide for further advances in modeling of aerodynamic flow fields, NASA has initiated at the Ames Research Center the Numerical Aerodynamic Simulation (NAS) Program. The objective of the Program is to develop a leading-edge, large-scale computer facility, and make it available to NASA, DoD, other Government agencies, industry and universities as a necessary element in ensuring continuing leadership in computational aerodynamics and related disciplines. The Program will establish an initial operational capability in 1986 and systematically enhance that capability by incorporating evolving improvements in state-of-the-art computer system technologies as required to maintain a leadership role. This paper briefly reviews the present and future requirements for computational aerodynamics and discusses the Numerical Aerodynamic Simulation Program objectives, computational goals, and implementation plans

Celles du Crétacé supérieur-Eocène de la bordure ouest et nord du bouclier africano-arabe sont quantitativement exceptionnelles et intéressantes par les réflexions qu'elles suggèrent sur un mécanisme global. On insiste d'abord sur certaines données océanographiques actuelles : flux des matières phosphatées vers l'océan et dans l'océan; répartition des phosphates dans les masses d'eaux océaniques et en particulier dans les eaux euxiniques. Puis quelques théories proposées pour rendre compte du caractère épisodique de la sédimentation phosphatée sont rappelées et critiquées (Strakhov, Fischer, Arthur, Sheldon, etc. . Puis la répartition par pays des quantités de phosphates déposées dans une partie des domaines mésogéen et atlantique est précisée. Elle justifie de focaliser notre attention sur les phosphates marocains, de loin les plus abondants et localisés en position clé. On rappelle néanmoins que la double évolution latitudinale au Crétacé et au Paléogène du Nord vers le Sud dans l'actuel hémisphère nord et du Sud vers le Nord dans l'actuel hémisphère sud rend peu crédibles les interprétations purement latitudino-climatiques de ces dépôts phosphatés. Sur le cas du Maroc, les conditions préalables à cette sédimentation phosphatée sont précisées et discutées : existence de transgressions marines pelliculaires, de séries condensées; rémission des apports détritiques ( le silence de la terre ; confinement (origine et modalité d'action. Ces conditions à elles seules ne peuvent pas expliquer l'extraordinaire flux phosphaté de cette époque.

On teaching computer ethics within a computer science department.

2006-04-01

The author has surveyed a quarter of the accredited undergraduate computer science programs in the United States. More than half of these programs offer a 'social and ethical implications of computing' course taught by a computer science faculty member, and there appears to be a trend toward teaching ethics classes within computer science departments. Although the decision to create an 'in house' computer ethics course may sometimes be a pragmatic response to pressure from the accreditation agency, this paper argues that teaching ethics within a computer science department can provide students and faculty members with numerous benefits. The paper lists topics that can be covered in a computer ethics course and offers some practical suggestions for making the course successful.

Parallel quantum computing in a single ensemble quantum computer

International Nuclear Information System (INIS)

Long Guilu; Xiao, L.

2004-01-01

We propose a parallel quantum computing mode for ensemble quantum computer. In this mode, some qubits are in pure states while other qubits are in mixed states. It enables a single ensemble quantum computer to perform 'single-instruction-multidata' type of parallel computation. Parallel quantum computing can provide additional speedup in Grover's algorithm and Shor's algorithm. In addition, it also makes a fuller use of qubit resources in an ensemble quantum computer. As a result, some qubits discarded in the preparation of an effective pure state in the Schulman-Varizani and the Cleve-DiVincenzo algorithms can be reutilized

Abstract Volunteer computing has come up as a new form of distributed computing. Unlike other computing paradigms like Grids, which use to be based on complex architectures, volunteer computing has demonstrated a great ability to integrate dispersed, heterogeneous computing resources with ease. This article presents ZIVIS, a project which aims to deploy a city-wide computing platform in Zaragoza (Spain). ZIVIS is based on BOINC (Berkeley Open Infrastructure for Network Computing), a popular open source framework to deploy volunteer and desktop grid computing systems. A scientific code which simulates the trajectories of particles moving inside a stellarator fusion device, has been chosen as the pilot application of the project. In this paper we describe the approach followed to port the code to the BOINC framework as well as some novel techniques, based on standard Grid protocols, we have used to access the output data present in the BOINC server from a remote visualizer.

Full Text Available Since the first idea of using GPU to general purpose computing, things have evolved over the years and now there are several approaches to GPU programming. GPU computing practically began with the introduction of CUDA (Compute Unified Device Architecture by NVIDIA and Stream by AMD. These are APIs designed by the GPU vendors to be used together with the hardware that they provide. A new emerging standard, OpenCL (Open Computing Language tries to unify different GPU general computing API implementations and provides a framework for writing programs executed across heterogeneous platforms consisting of both CPUs and GPUs. OpenCL provides parallel computing using task-based and data-based parallelism. In this paper we will focus on the CUDA parallel computing architecture and programming model introduced by NVIDIA. We will present the benefits of the CUDA programming model. We will also compare the two main approaches, CUDA and AMD APP (STREAM and the new framwork, OpenCL that tries to unify the GPGPU computing models.

Fast computation of the characteristics method on vector computers

International Nuclear Information System (INIS)

Kugo, Teruhiko

2001-11-01

Fast computation of the characteristics method to solve the neutron transport equation in a heterogeneous geometry has been studied. Two vector computation algorithms; an odd-even sweep (OES) method and an independent sequential sweep (ISS) method have been developed and their efficiency to a typical fuel assembly calculation has been investigated. For both methods, a vector computation is 15 times faster than a scalar computation. From a viewpoint of comparison between the OES and ISS methods, the followings are found: 1) there is a small difference in a computation speed, 2) the ISS method shows a faster convergence and 3) the ISS method saves about 80% of computer memory size compared with the OES method. It is, therefore, concluded that the ISS method is superior to the OES method as a vectorization method. In the vector computation, a table-look-up method to reduce computation time of an exponential function saves only 20% of a whole computation time. Both the coarse mesh rebalance method and the Aitken acceleration method are effective as acceleration methods for the characteristics method, a combination of them saves 70-80% of outer iterations compared with a free iteration.

As computers become ever more complex, they inevitably become smaller. This leads to a need for components which are fabricated and operate on increasingly smaller size scales. Quantum theory is already taken into account in microelectronics design. This article explores how quantum theory will need to be incorporated into computers in future in order to give them their components functionality. Computation tasks which depend on quantum effects will become possible. Physicists may have to reconsider their perspective on computation in the light of understanding developed in connection with universal quantum computers. (UK)

Software is the component in a computer system that permits the hardware to perform the various functions that a computer system is capable of doing. The history of software and its development can be traced to the early nineteenth century. All computer systems are designed to utilize the "stored program concept" as first developed by Charles Babbage in the 1850s. The concept was lost until the mid-1940s, when modern computers made their appearance. Today, because of the complex and myriad tasks that a computer system can perform, there has been a differentiation of types of software. There is software designed to perform specific business applications. There is software that controls the overall operation of a computer system. And there is software that is designed to carry out specialized tasks. Regardless of types, software is the most critical component of any computer system. Without it, all one has is a collection of circuits, transistors, and silicone chips.

Framework for Computation Offloading in Mobile Cloud Computing

Directory of Open Access Journals (Sweden)

Dejan Kovachev

2012-12-01

Full Text Available The inherently limited processing power and battery lifetime of mobile phones hinder the possible execution of computationally intensive applications like content-based video analysis or 3D modeling. Offloading of computationally intensive application parts from the mobile platform into a remote cloud infrastructure or nearby idle computers addresses this problem. This paper presents our Mobile Augmentation Cloud Services (MACS middleware which enables adaptive extension of Android application execution from a mobile client into the cloud. Applications are developed by using the standard Android development pattern. The middleware does the heavy lifting of adaptive application partitioning, resource monitoring and computation offloading. These elastic mobile applications can run as usual mobile application, but they can also use remote computing resources transparently. Two prototype applications using the MACS middleware demonstrate the benefits of the approach. The evaluation shows that applications, which involve costly computations, can benefit from offloading with around 95% energy savings and significant performance gains compared to local execution only.

2008-01-01

Organic Computing is a research field emerging around the conviction that problems of organization in complex systems in computer science, telecommunications, neurobiology, molecular biology, ethology, and possibly even sociology can be tackled scientifically in a unified way. From the computer science point of view, the apparent ease in which living systems solve computationally difficult problems makes it inevitable to adopt strategies observed in nature for creating information processing machinery. In this book, the major ideas behind Organic Computing are delineated, together with a sparse sample of computational projects undertaken in this new field. Biological metaphors include evolution, neural networks, gene-regulatory networks, networks of brain modules, hormone system, insect swarms, and ant colonies. Applications are as diverse as system design, optimization, artificial growth, task allocation, clustering, routing, face recognition, and sign language understanding.

Harmonising the balancing market Issues to be considered

Energy Technology Data Exchange (ETDEWEB)

2010-07-15

One of the work streams established in NordREG Work Programme for 2009 is related to the Nordic balancing power market and balance management. One of the tasks is to follow up the implementation of the common balance management according to what was described above, the other task is related to the efficient functioning of the Nordic balancing power market. While it has been noted that the Nordic wholesale market functions well, there is an expectation that further harmonization of the Nordic balancing power market would improve the efficiency of the market and form the basis for further integration with adjacent markets in the area of balancing services. Therefore NordREG has taken on to investigate in which areas further harmonization can be expected to be cost-efficient and contribute to a better functioning market and how this harmonized market could be monitored. The task according to the work programme is: 'In its initial work regarding Nordic balancing, NordREG noted that the common Nordic list for bids in regulation power works fairly well. However, there seems to be scope for increased efficiency. This might be attained by identifying important differences in the framework between countries as well as proposing a genuine Nordic harmonisation. It is important initially to discuss to what degree harmonisation is necessary in order to improve the efficient functioning of the market. 'In approaching these topics, NordREG has been discussing with the Nordic TSOs, where appropriate, and has made use of Nordel's publications on this topic. This report provides an overview of the current state of integration and harmonization of balancing in the Nordic region. The report also provides a summary of the harmonization measures that might be implemented in the future

Parallel computing works

Energy Technology Data Exchange (ETDEWEB)

1991-10-23

An account of the Caltech Concurrent Computation Program (C{sup 3}P), a five year project that focused on answering the question: Can parallel computers be used to do large-scale scientific computations '' As the title indicates, the question is answered in the affirmative, by implementing numerous scientific applications on real parallel computers and doing computations that produced new scientific results. In the process of doing so, C{sup 3}P helped design and build several new computers, designed and implemented basic system software, developed algorithms for frequently used mathematical computations on massively parallel machines, devised performance models and measured the performance of many computers, and created a high performance computing facility based exclusively on parallel computers. While the initial focus of C{sup 3}P was the hypercube architecture developed by C. Seitz, many of the methods developed and lessons learned have been applied successfully on other massively parallel architectures.

Contribution to a study of real time information systems for elementary particle physics

International Nuclear Information System (INIS)

Meyer, J.-M.

1977-01-01

The structure of data acquisition systems used in elementary particle physics experiments is formulated. The experiments and the equipment used from a data processing point of view are characterized and the acquisition system is modeled to obtain an optimal architecture. Practical compromises are implemented, leading to a system with a new structure, now being used at the CERN SPS in a hyperon experiment. The realization of this system (FAS) is described using three computers: a NORD-10, a DDP and GESPRO. The latter is an original device built using INTEL-3000 integrated circuits. GESPRO can be microprogramed with instructions specialized for use with CAMAC. Finally, the software for the entire FAS system is given. This includes the assembler, test programs for CAMAC, management programs for the memory, etc [fr

Computational Streetscapes

Directory of Open Access Journals (Sweden)

Paul M. Torrens

2016-09-01

Full Text Available Streetscapes have presented a long-standing interest in many fields. Recently, there has been a resurgence of attention on streetscape issues, catalyzed in large part by computing. Because of computing, there is more understanding, vistas, data, and analysis of and on streetscape phenomena than ever before. This diversity of lenses trained on streetscapes permits us to address long-standing questions, such as how people use information while mobile, how interactions with people and things occur on streets, how we might safeguard crowds, how we can design services to assist pedestrians, and how we could better support special populations as they traverse cities. Amid each of these avenues of inquiry, computing is facilitating new ways of posing these questions, particularly by expanding the scope of what-if exploration that is possible. With assistance from computing, consideration of streetscapes now reaches across scales, from the neurological interactions that form among place cells in the brain up to informatics that afford real-time views of activity over whole urban spaces. For some streetscape phenomena, computing allows us to build realistic but synthetic facsimiles in computation, which can function as artificial laboratories for testing ideas. In this paper, I review the domain science for studying streetscapes from vantages in physics, urban studies, animation and the visual arts, psychology, biology, and behavioral geography. I also review the computational developments shaping streetscape science, with particular emphasis on modeling and simulation as informed by data acquisition and generation, data models, path-planning heuristics, artificial intelligence for navigation and way-finding, timing, synthetic vision, steering routines, kinematics, and geometrical treatment of collision detection and avoidance. I also discuss the implications that the advances in computing streetscapes might have on emerging developments in cyber

Abstract quantum computing machines and quantum computational logics

Science.gov (United States)

Chiara, Maria Luisa Dalla; Giuntini, Roberto; Sergioli, Giuseppe; Leporini, Roberto

2016-06-01

Classical and quantum parallelism are deeply different, although it is sometimes claimed that quantum Turing machines are nothing but special examples of classical probabilistic machines. We introduce the concepts of deterministic state machine, classical probabilistic state machine and quantum state machine. On this basis, we discuss the question: To what extent can quantum state machines be simulated by classical probabilistic state machines? Each state machine is devoted to a single task determined by its program. Real computers, however, behave differently, being able to solve different kinds of problems. This capacity can be modeled, in the quantum case, by the mathematical notion of abstract quantum computing machine, whose different programs determine different quantum state machines. The computations of abstract quantum computing machines can be linguistically described by the formulas of a particular form of quantum logic, termed quantum computational logic.

Context We define the scope and needs within the new discipline of computational pathology, a discipline critical to the future of both the practice of pathology and, more broadly, medical practice in general. Objective To define the scope and needs of computational pathology. Data Sources A meeting was convened in Boston, Massachusetts, in July 2014 prior to the annual Association of Pathology Chairs meeting, and it was attended by a variety of pathologists, including individuals highly invested in pathology informatics as well as chairs of pathology departments. Conclusions The meeting made recommendations to promote computational pathology, including clearly defining the field and articulating its value propositions; asserting that the value propositions for health care systems must include means to incorporate robust computational approaches to implement data-driven methods that aid in guiding individual and population health care; leveraging computational pathology as a center for data interpretation in modern health care systems; stating that realizing the value proposition will require working with institutional administrations, other departments, and pathology colleagues; declaring that a robust pipeline should be fostered that trains and develops future computational pathologists, for those with both pathology and non-pathology backgrounds; and deciding that computational pathology should serve as a hub for data-related research in health care systems. The dissemination of these recommendations to pathology and bioinformatics departments should help facilitate the development of computational pathology. PMID:26098131

Full Text Available What is computer-assisted accounting? Where is the place and what is the role of the computer in the financial-accounting activity? What is the position and importance of the computer in the accountant’s activity? All these are questions that require scientific research in order to find the answers. The paper approaches the issue of the support granted to the accountant to organize and manage the accounting activity by the computer. Starting from the notions of accounting and computer, the concept of computer-assisted accounting is introduced, it has a general character and it refers to the accounting performed with the help of the computer or using the computer to automate the procedures performed by the person who is doing the accounting activity; this is a concept used to define the computer applications of the accounting activity. The arguments regarding the use of the computer to assist accounting targets the accounting informatization, the automating of the financial-accounting activities and the endowment with modern technology of the contemporary accounting.

Full Text Available Im Zuge der Digitalisierung aller Lebensbereiche im 21. Jahrhundert, die sich auch im Bibliotheksbereich niederschlägt, gewinnt die Automatisierung von Arbeitsabläufen durch Softwareeinsatz eine ganze neue Bedeutung. Die zunehmende Vernetzung sowie webbasierte und für mobile Endgeräte optimierte Services eröffnen neue Nutzungsszenarien, die über das Vorhandene weit hinausgehen, und von Politik und Wirtschaft unter der Überschrift „Wirtschaft 4.0“ längst intensiv rezipiert werden. Am Beispiel des neuen Lern- und Studiengebäudes (LSG und der Verbesserungen der Studien- und Lernbedingungen am Campus-Nord der Universität Göttingen wird gezeigt, wie sich die Benutzungsservices für Studierende in den letzten Jahren einschneidend verändert haben und zu einer deutlichen Verbesserung der Lern- und Studienbedingungen auf dem Göttinger Campus geführt haben. Eine zentrale Voraussetzung dabei war die frühzeitige Partizipation der zukünftigen Nutzer/innen sowie eine konsequent bedarfsorientierte Planung. As all areas of life become more and more digitized in the 21st century, which can also be seen in the library landscape, the automation of workflows by means of software gains a whole new meaning. Increased networking as well as services which are web-based and optimized for mobile devices open up new usage scenarios which go far beyond what is presently common. In the context of “Economy 4.0”, these developments have long received the close attention of both the political and the economic sector. Using the example of the new Learning and Study Building (LSG and the redevelopment of the North Campus of the University of Göttingen, the article shows how this general trend has been translated into specific user services for students, substantially changing these services and leading to a significant improvement in the learning and study conditions on the Göttingen campus.

Touchable Computing: Computing-Inspired Bio-Detection.

Science.gov (United States)

Chen, Yifan; Shi, Shaolong; Yao, Xin; Nakano, Tadashi

2017-12-01

We propose a new computing-inspired bio-detection framework called touchable computing (TouchComp). Under the rubric of TouchComp, the best solution is the cancer to be detected, the parameter space is the tissue region at high risk of malignancy, and the agents are the nanorobots loaded with contrast medium molecules for tracking purpose. Subsequently, the cancer detection procedure (CDP) can be interpreted from the computational optimization perspective: a population of externally steerable agents (i.e., nanorobots) locate the optimal solution (i.e., cancer) by moving through the parameter space (i.e., tissue under screening), whose landscape (i.e., a prescribed feature of tissue environment) may be altered by these agents but the location of the best solution remains unchanged. One can then infer the landscape by observing the movement of agents by applying the "seeing-is-sensing" principle. The term "touchable" emphasizes the framework's similarity to controlling by touching the screen with a finger, where the external field for controlling and tracking acts as the finger. Given this analogy, we aim to answer the following profound question: can we look to the fertile field of computational optimization algorithms for solutions to achieve effective cancer detection that are fast, accurate, and robust? Along this line of thought, we consider the classical particle swarm optimization (PSO) as an example and propose the PSO-inspired CDP, which differs from the standard PSO by taking into account realistic in vivo propagation and controlling of nanorobots. Finally, we present comprehensive numerical examples to demonstrate the effectiveness of the PSO-inspired CDP for different blood flow velocity profiles caused by tumor-induced angiogenesis. The proposed TouchComp bio-detection framework may be regarded as one form of natural computing that employs natural materials to compute.

Single and Multi-Objective Evolutionary Computation (MOEA),  Genetic Algorithms (GAs), Artificial Neural Networks (ANNs), Fuzzy Controllers (FCs), Particle Swarm Optimization (PSO) and Ant colony Optimization (ACO) are becoming omnipresent in almost every intelligent system design. Unfortunately, the application of the majority of these techniques is complex and so requires a huge computational effort to yield useful and practical results. Therefore, dedicated hardware for evolutionary, neural and fuzzy computation is a key issue for designers. With the spread of reconfigurable hardware such as FPGAs, digital as well as analog hardware implementations of such computation become cost-effective. The idea behind this book is to offer a variety of hardware designs for soft computing techniques that can be embedded in any final product. Also, to introduce the successful application of soft computing technique to solve many hard problem encountered during the design of embedded hardware designs. Reconfigurable em...

Computational Science is an integral component of Brookhaven's multi science mission, and is a reflection of the increased role of computation across all of science. Brookhaven currently has major efforts in data storage and analysis for the Relativistic Heavy Ion Collider (RHIC) and the ATLAS detector at CERN, and in quantum chromodynamics. The Laboratory is host for the QCDOC machines (quantum chromodynamics on a chip), 10 teraflop/s computers which boast 12,288 processors each. There are two here, one for the Riken/BNL Research Center and the other supported by DOE for the US Lattice Gauge Community and other scientific users. A 100 teraflop/s supercomputer will be installed at Brookhaven in the coming year, managed jointly by Brookhaven and Stony Brook, and funded by a grant from New York State. This machine will be used for computational science across Brookhaven's entire research program, and also by researchers at Stony Brook and across New York State. With Stony Brook, Brookhaven has formed the New York Center for Computational Science (NYCCS) as a focal point for interdisciplinary computational science, which is closely linked to Brookhaven's Computational Science Center (CSC). The CSC has established a strong program in computational science, with an emphasis on nanoscale electronic structure and molecular dynamics, accelerator design, computational fluid dynamics, medical imaging, parallel computing and numerical algorithms.

The pace of extraordinary advances in molecular biology has accelerated in the past decade due in large part to discoveries coming from genome projects on human and model organisms. The advances in the genome project so far, happening well ahead of schedule and under budget, have exceeded any dreams by its protagonists, let alone formal expectations. Biologists expect the next phase of the genome project to be even more startling in terms of dramatic breakthroughs in our understanding of human biology, the biology of health and of disease. Only today can biologists begin to envision the necessary experimental, computational and theoretical steps necessary to exploit genome sequence information for its medical impact, its contribution to biotechnology and economic competitiveness, and its ultimate contribution to environmental quality. High performance computing has become one of the critical enabling technologies, which will help to translate this vision of future advances in biology into reality. Biologists are increasingly becoming aware of the potential of high performance computing. The goal of this tutorial is to introduce the exciting new developments in computational biology and genomics to the high performance computing community.

Quantum analogue computing.

Science.gov (United States)

Kendon, Vivien M; Nemoto, Kae; Munro, William J

2010-08-13

We briefly review what a quantum computer is, what it promises to do for us and why it is so hard to build one. Among the first applications anticipated to bear fruit is the quantum simulation of quantum systems. While most quantum computation is an extension of classical digital computation, quantum simulation differs fundamentally in how the data are encoded in the quantum computer. To perform a quantum simulation, the Hilbert space of the system to be simulated is mapped directly onto the Hilbert space of the (logical) qubits in the quantum computer. This type of direct correspondence is how data are encoded in a classical analogue computer. There is no binary encoding, and increasing precision becomes exponentially costly: an extra bit of precision doubles the size of the computer. This has important consequences for both the precision and error-correction requirements of quantum simulation, and significant open questions remain about its practicality. It also means that the quantum version of analogue computers, continuous-variable quantum computers, becomes an equally efficient architecture for quantum simulation. Lessons from past use of classical analogue computers can help us to build better quantum simulators in future.

The monitoring of Cs-137 fall-out from the Chernobyl accident in 1986, started the same year. Several plants and wild reindeer in natural ecosystems in Nord-Rondane have been followed annually ever since. Four more wild reindeer ranges were included in 2001: Setesdal-Ryfylkeheiene, Hardangervidda, Nord-Ottadalen, Snoehetta and Nord-Rondane. From 2007 Forollhogna was also included. On fixed plots in Nord-Rondane and Snoehetta some of the reindeer forage plants, including both higher plants and fruticose lichens, have been sampled and analyzed annually since 1986. This was also done in 2010. In addition plants and lichens were sampled at five locations along an altitudinal gradient at Soendre Knutshoe, and at 7-8 locations along an east-west gradient from Kollaflata to Skarhoe in the Jora valley continuing along the Aursjoe to Torbudalen. All these locations were sampled annually between 1987-1990, but they have not been sampled since. In 2010 samples from red deer and moose was also collected from eight different regions located within the following counties: Oppland, Telemark, Vest-Agder, Rogaland, Sogn and Fjordane, Nord-Troendelag, Nordland and Troms. Red deer were sampled in four regions and moose in six. Both species were sampled in Oppland. In 2010 76, 49 and 61 samples were collected from wild reindeer, red deer and moose respectively. All measures of caesium levels were performed on dried samples. For the 596 samples of plants and lichen the results refer to caesium-levels in dried samples. For the meat samples, results refer to caesium-137 levels in raw meat. Due to large variation in measured levels of caesium within species and sampling area, we give median values instead of mean values.The highest caesium levels in wild reindeer were found in Snoehetta (1010 Bq/kg) and Nord-Rondane (2686 Bq/kg). The levels found in the other areas were considerably lower. The highest caesium levels in both red deer (Sel, 677 Bq/kg) and moose (Vaaga, 365 Bq/kg) were found

What distinguishes our presentation from that of others is our focus on the relationship between quantum computation and computer science. Specifically, our emphasis is on the computational model of quantum computing rather than on the engineering issues associated with its physical implementation. We adopt this approach for the same reason that a book on computer programming doesn't cover the theory and physical realization of semiconductors. Another distin

The Computing Project is preparing for a busy year where the primary emphasis of the project moves towards steady operations. Following the very successful completion of Computing Software and Analysis challenge, CSA06, last fall, we have reorganized and established four groups in computing area: Commissioning, User Support, Facility/Infrastructure Operations and Data Operations. These groups work closely together with groups from the Offline Project in planning for data processing and operations. Monte Carlo production has continued since CSA06, with about 30M events produced each month to be used for HLT studies and physics validation. Monte Carlo production will continue throughout the year in the preparation of large samples for physics and detector studies ramping to 50 M events/month for CSA07. Commissioning of the full CMS computing system is a major goal for 2007. Site monitoring is an important commissioning component and work is ongoing to devise CMS specific tests to be included in Service Availa...

Introduction More than seventy CMS collaborators attended the Computing and Offline Workshop in San Diego, California, April 20-24th to discuss the state of readiness of software and computing for collisions. Focus and priority were given to preparations for data taking and providing room for ample dialog between groups involved in Commissioning, Data Operations, Analysis and MC Production. Throughout the workshop, aspects of software, operating procedures and issues addressing all parts of the computing model were discussed. Plans for the CMS participation in STEP’09, the combined scale testing for all four experiments due in June 2009, were refined. The article in CMS Times by Frank Wuerthwein gave a good recap of the highly collaborative atmosphere of the workshop. Many thanks to UCSD and to the organizers for taking care of this workshop, which resulted in a long list of action items and was definitely a success. A considerable amount of effort and care is invested in the estimate of the comput...

The authors have continued to enhance their ability to use new massively parallel processing computers to solve time-domain electromagnetic problems. New vectorization techniques have improved the performance of their code DSI3D by factors of 5 to 15, depending on the computer used. New radiation boundary conditions and far-field transformations now allow the computation of radar cross-section values for complex objects. A new parallel-data extraction code has been developed that allows the extraction of data subsets from large problems, which have been run on parallel computers, for subsequent post-processing on workstations with enhanced graphics capabilities. A new charged-particle-pushing version of DSI3D is under development. Finally, DSI3D has become a focal point for several new Cooperative Research and Development Agreement activities with industrial companies such as Lockheed Advanced Development Company, Varian, Hughes Electron Dynamics Division, General Atomic, and Cray

Computational Science is an integral component of Brookhaven's multi science mission, and is a reflection of the increased role of computation across all of science. Brookhaven currently has major efforts in data storage and analysis for the Relativistic Heavy Ion Collider (RHIC) and the ATLAS detector at CERN, and in quantum chromodynamics. The Laboratory is host for the QCDOC machines (quantum chromodynamics on a chip), 10 teraflop/s computers which boast 12,288 processors each. There are two here, one for the Riken/BNL Research Center and the other supported by DOE for the US Lattice Gauge Community and other scientific users. A 100 teraflop/s supercomputer will be installed at Brookhaven in the coming year, managed jointly by Brookhaven and Stony Brook, and funded by a grant from New York State. This machine will be used for computational science across Brookhaven's entire research program, and also by researchers at Stony Brook and across New York State. With Stony Brook, Brookhaven has formed the New York Center for Computational Science (NYCCS) as a focal point for interdisciplinary computational science, which is closely linked to Brookhaven's Computational Science Center (CSC). The CSC has established a strong program in computational science, with an emphasis on nanoscale electronic structure and molecular dynamics, accelerator design, computational fluid dynamics, medical imaging, parallel computing and numerical algorithms. We have been an active participant in DOES SciDAC program (Scientific Discovery through Advanced Computing). We are also planning a major expansion in computational biology in keeping with Laboratory initiatives. Additional laboratory initiatives with a dependence on a high level of computation include the development of hydrodynamics models for the interpretation of RHIC data, computational models for the atmospheric transport of aerosols, and models for combustion and for energy utilization. The CSC was formed to

The subject of quantum computing brings together ideas from classical information theory, computer science, and quantum physics. This review aims to summarize not just quantum computing, but the whole subject of quantum information theory. Information can be identified as the most general thing which must propagate from a cause to an effect. It therefore has a fundamentally important role in the science of physics. However, the mathematical treatment of information, especially information processing, is quite recent, dating from the mid-20th century. This has meant that the full significance of information as a basic concept in physics is only now being discovered. This is especially true in quantum mechanics. The theory of quantum information and computing puts this significance on a firm footing, and has led to some profound and exciting new insights into the natural world. Among these are the use of quantum states to permit the secure transmission of classical information (quantum cryptography), the use of quantum entanglement to permit reliable transmission of quantum states (teleportation), the possibility of preserving quantum coherence in the presence of irreversible noise processes (quantum error correction), and the use of controlled quantum evolution for efficient computation (quantum computation). The common theme of all these insights is the use of quantum entanglement as a computational resource. It turns out that information theory and quantum mechanics fit together very well. In order to explain their relationship, this review begins with an introduction to classical information theory and computer science, including Shannon's theorem, error correcting codes, Turing machines and computational complexity. The principles of quantum mechanics are then outlined, and the Einstein, Podolsky and Rosen (EPR) experiment described.

Nash equilibrium constitutes a central solution concept in game theory. The task of detecting the Nash equilibria of a finite strategic game remains a challenging problem up-to-date. This paper investigates the effectiveness of three computational intelligence techniques, namely, covariance matrix adaptation evolution strategies, particle swarm optimization, as well as, differential evolution, to compute Nash equilibria of finite strategic games, as global minima of a real-valued, nonnegative function. An issue of particular interest is to detect more than one Nash equilibria of a game. The performance of the considered computational intelligence methods on this problem is investigated using multistart and deflection.

The latest developments in mobile computing technology have enabled intensive applications on the modern Smartphones. However, such applications are still constrained by limitations in processing potentials, storage capacity and battery lifetime of the Smart Mobile Devices (SMDs). Therefore, Mobile Cloud Computing (MCC) leverages the application processing services of computational clouds for mitigating resources limitations in SMDs. Currently, a number of computational offloading frameworks are proposed for MCC wherein the intensive components of the application are outsourced to computational clouds. Nevertheless, such frameworks focus on runtime partitioning of the application for computational offloading, which is time consuming and resources intensive. The resource constraint nature of SMDs require lightweight procedures for leveraging computational clouds. Therefore, this paper presents a lightweight framework which focuses on minimizing additional resources utilization in computational offloading for MCC. The framework employs features of centralized monitoring, high availability and on demand access services of computational clouds for computational offloading. As a result, the turnaround time and execution cost of the application are reduced. The framework is evaluated by testing prototype application in the real MCC environment. The lightweight nature of the proposed framework is validated by employing computational offloading for the proposed framework and the latest existing frameworks. Analysis shows that by employing the proposed framework for computational offloading, the size of data transmission is reduced by 91%, energy consumption cost is minimized by 81% and turnaround time of the application is decreased by 83.5% as compared to the existing offloading frameworks. Hence, the proposed framework minimizes additional resources utilization and therefore offers lightweight solution for computational offloading in MCC. PMID:25127245

Full Text Available Introduction : Même si certaines études suggèrent une association entre le travail par quarts et l’obésité, peu sont fondées sur la population ou tiennent compte de divers horaires de travail par quarts. L’obésité étant associée à plusieurs problèmes de santé chroniques, il est important de comprendre quelles formes de travail par quarts ont une incidence sur elle et d’effectuer des travaux permettant d’évaluer de façon plus détaillée l’exposition au travail par quarts. Méthodologie : Au moyen d’une régression logistique polytomique multivariée, nous avons étudié l’association entre le travail par quarts (de soir ou nuit, par quarts ou autre type de rotation et le surpoids et l’obésité, en fonction d’une mesure transversale de l’indice de masse corporelle chez 1 561 hommes. Ces hommes avaient déjà servi de témoins dans une étude cas-témoins sur le cancer de la prostate menée dans le nord-est de l’Ontario de 1995 à 1999. Nous avons obtenu l’information sur leurs antécédents de travail (notamment sur le travail par quarts, leur taille et leur poids à partir de données autodéclarées recueillies par questionnaire. Résultats : Nous avons observé une association entre le fait d’avoir déjà travaillé par quarts (par opposition au fait de n’avoir jamais travaillé par quarts et le surpoids (RC [rapport de cotes] = 1,34; IC [intervalle de confiance] à 95 % : 1,05 à 1,73 ainsi que l’obésité (RC = 1,57; IC à 95 % : 1,12 à 2,21. Nous avons également observé des associations statistiquement non significatives avec le fait d’avoir déjà travaillé (par opposition au fait de n’avoir jamais travaillé de façon permanente selon un quart de soir ou de nuit. Nous avons par ailleurs observé une tendance à la hausse statistiquement significative en ce qui concerne le risque de surpoids et d’obésité en fonction de la durée du travail par quarts.

Full Text Available Research in Intelligent Agents has yielded interesting results, some of which have been translated into commer­cial ventures. Intelligent Agents are executable software components that represent the user, perform tasks on behalf of the user and when the task terminates, the Agents send the result to the user. Intelligent Agents are best suited for the Internet: a collection of computers connected together in a world-wide computer network. Swarm and HYDRA computer architectures for Agents’ execution were developed at the University of Surrey, UK in the 90s. The objective of the research was to develop a software-based computer architecture on which Agents execution could be explored. The combination of Intelligent Agents and HYDRA computer architecture gave rise to a new computer concept: the NET-Computer in which the comput­ing resources reside on the Internet. The Internet computers form the hardware and software resources, and the user is provided with a simple interface to access the Internet and run user tasks. The Agents autonomously roam the Internet (NET-Computer executing the tasks. A growing segment of the Internet is E-Commerce for online shopping for products and services. The Internet computing resources provide a marketplace for product suppliers and consumers alike. Consumers are looking for suppliers selling products and services, while suppliers are looking for buyers. Searching the vast amount of information available on the Internet causes a great deal of problems for both consumers and suppliers. Intelligent Agents executing on the NET-Computer can surf through the Internet and select specific information of interest to the user. The simulation results show that Intelligent Agents executing HYDRA computer architecture could be applied in E-Commerce.

Disciplines, models, and computers: the path to computational quantum chemistry.

Science.gov (United States)

Lenhard, Johannes

2014-12-01

Many disciplines and scientific fields have undergone a computational turn in the past several decades. This paper analyzes this sort of turn by investigating the case of computational quantum chemistry. The main claim is that the transformation from quantum to computational quantum chemistry involved changes in three dimensions. First, on the side of instrumentation, small computers and a networked infrastructure took over the lead from centralized mainframe architecture. Second, a new conception of computational modeling became feasible and assumed a crucial role. And third, the field of computa- tional quantum chemistry became organized in a market-like fashion and this market is much bigger than the number of quantum theory experts. These claims will be substantiated by an investigation of the so-called density functional theory (DFT), the arguably pivotal theory in the turn to computational quantum chemistry around 1990.

A Computational Fluid Dynamics Algorithm on a Massively Parallel Computer

Jespersen, Dennis C.; Levit, Creon

1989-01-01

The discipline of computational fluid dynamics is demanding ever-increasing computational power to deal with complex fluid flow problems. We investigate the performance of a finite-difference computational fluid dynamics algorithm on a massively parallel computer, the Connection Machine. Of special interest is an implicit time-stepping algorithm; to obtain maximum performance from the Connection Machine, it is necessary to use a nonstandard algorithm to solve the linear systems that arise in the implicit algorithm. We find that the Connection Machine ran achieve very high computation rates on both explicit and implicit algorithms. The performance of the Connection Machine puts it in the same class as today's most powerful conventional supercomputers.

Introduction It has been a very active quarter in Computing with interesting progress in all areas. The activity level at the computing facilities, driven by both organised processing from data operations and user analysis, has been steadily increasing. The large-scale production of simulated events that has been progressing throughout the fall is wrapping-up and reprocessing with pile-up will continue. A large reprocessing of all the proton-proton data has just been released and another will follow shortly. The number of analysis jobs by users each day, that was already hitting the computing model expectations at the time of ICHEP, is now 33% higher. We are expecting a busy holiday break to ensure samples are ready in time for the winter conferences. Heavy Ion An activity that is still in progress is computing for the heavy-ion program. The heavy-ion events are collected without zero suppression, so the event size is much large at roughly 11 MB per event of RAW. The central collisions are more complex and...

OBJECTIVES To compare the accuracy of pulmonary lobar volumetry using the conventional number of segments method and novel volumetric computer-aided diagnosis using 3D computed tomography images. METHODS We acquired 50 consecutive preoperative 3D computed tomography examinations for lung tumours reconstructed at 1-mm slice thicknesses. We calculated the lobar volume and the emphysematous lobar volume volumetry computer-aided diagnosis system could more precisely measure lobar volumes than the conventional number of segments method. Because semi-automatic computer-aided diagnosis and automatic computer-aided diagnosis were complementary, in clinical use, it would be more practical to first measure volumes by automatic computer-aided diagnosis, and then use semi-automatic measurements if automatic computer-aided diagnosis failed.

Cloud Computing as Evolution of Distributed Computing – A Case Study for SlapOS Distributed Cloud Computing Platform

Directory of Open Access Journals (Sweden)

George SUCIU

2013-01-01

Full Text Available The cloud computing paradigm has been defined from several points of view, the main two directions being either as an evolution of the grid and distributed computing paradigm, or, on the contrary, as a disruptive revolution in the classical paradigms of operating systems, network layers and web applications. This paper presents a distributed cloud computing platform called SlapOS, which unifies technologies and communication protocols into a new technology model for offering any application as a service. Both cloud and distributed computing can be efficient methods for optimizing resources that are aggregated from a grid of standard PCs hosted in homes, offices and small data centers. The paper fills a gap in the existing distributed computing literature by providing a distributed cloud computing model which can be applied for deploying various applications.

Review of quantum computation

International Nuclear Information System (INIS)

Lloyd, S.

1992-01-01

Digital computers are machines that can be programmed to perform logical and arithmetical operations. Contemporary digital computers are ''universal,'' in the sense that a program that runs on one computer can, if properly compiled, run on any other computer that has access to enough memory space and time. Any one universal computer can simulate the operation of any other; and the set of tasks that any such machine can perform is common to all universal machines. Since Bennett's discovery that computation can be carried out in a non-dissipative fashion, a number of Hamiltonian quantum-mechanical systems have been proposed whose time-evolutions over discrete intervals are equivalent to those of specific universal computers. The first quantum-mechanical treatment of computers was given by Benioff, who exhibited a Hamiltonian system with a basis whose members corresponded to the logical states of a Turing machine. In order to make the Hamiltonian local, in the sense that its structure depended only on the part of the computation being performed at that time, Benioff found it necessary to make the Hamiltonian time-dependent. Feynman discovered a way to make the computational Hamiltonian both local and time-independent by incorporating the direction of computation in the initial condition. In Feynman's quantum computer, the program is a carefully prepared wave packet that propagates through different computational states. Deutsch presented a quantum computer that exploits the possibility of existing in a superposition of computational states to perform tasks that a classical computer cannot, such as generating purely random numbers, and carrying out superpositions of computations as a method of parallel processing. In this paper, we show that such computers, by virtue of their common function, possess a common form for their quantum dynamics

2012-01-01

What can we compute--even with unlimited resources? Is everything within reach? Or are computations necessarily drastically limited, not just in practice, but theoretically? These questions are at the heart of computability theory. The goal of this book is to give the reader a firm grounding in the fundamentals of computability theory and an overview of currently active areas of research, such as reverse mathematics and algorithmic randomness. Turing machines and partial recursive functions are explored in detail, and vital tools and concepts including coding, uniformity, and diagonalization are described explicitly. From there the material continues with universal machines, the halting problem, parametrization and the recursion theorem, and thence to computability for sets, enumerability, and Turing reduction and degrees. A few more advanced topics round out the book before the chapter on areas of research. The text is designed to be self-contained, with an entire chapter of preliminary material including re...

We present a computational framework based on geometric structures. No quantum mechanics is involved, and yet the algorithms perform tasks analogous to quantum computation. Tensor products and entangled states are not needed-they are replaced by sets of basic shapes. To test the formalism we solve in geometric terms the Deutsch-Jozsa problem, historically the first example that demonstrated the potential power of quantum computation. Each step of the algorithm has a clear geometric interpretation and allows for a cartoon representation. (fast track communication)

The program can be targeted toward exploiting the time domain because other programs in the Center are pursuing research on parallel optical systems, exploiting optical interconnection and optical devices and materials. Using a general purpose computing architecture as the focus, we are developing design techniques, tools and architecture for operation at the speed of light limit. Experimental work is being done with the somewhat low speed components currently available but with architectures which will scale up in speed as faster devices are developed. The design algorithms and tools developed for a general purpose, stored program computer are being applied to other systems such as optimally controlled optical communication networks.

Community Cloud Computing

Marinos, Alexandros; Briscoe, Gerard

Cloud Computing is rising fast, with its data centres growing at an unprecedented rate. However, this has come with concerns over privacy, efficiency at the expense of resilience, and environmental sustainability, because of the dependence on Cloud vendors such as Google, Amazon and Microsoft. Our response is an alternative model for the Cloud conceptualisation, providing a paradigm for Clouds in the community, utilising networked personal computers for liberation from the centralised vendor model. Community Cloud Computing (C3) offers an alternative architecture, created by combing the Cloud with paradigms from Grid Computing, principles from Digital Ecosystems, and sustainability from Green Computing, while remaining true to the original vision of the Internet. It is more technically challenging than Cloud Computing, having to deal with distributed computing issues, including heterogeneous nodes, varying quality of service, and additional security constraints. However, these are not insurmountable challenges, and with the need to retain control over our digital lives and the potential environmental consequences, it is a challenge we must pursue.

With the advent of supercomputers, modern computational chemistry algorithms and codes, a powerful tool was created to help fill NASA's continuing need for information on the properties of matter in hostile or unusual environments. Computational resources provided under the National Aerodynamics Simulator (NAS) program were a cornerstone for recent advancements in this field. Properties of gases, materials, and their interactions can be determined from solutions of the governing equations. In the case of gases, for example, radiative transition probabilites per particle, bond-dissociation energies, and rates of simple chemical reactions can be determined computationally as reliably as from experiment. The data are proving to be quite valuable in providing inputs to real-gas flow simulation codes used to compute aerothermodynamic loads on NASA's aeroassist orbital transfer vehicles and a host of problems related to the National Aerospace Plane Program. Although more approximate, similar solutions can be obtained for ensembles of atoms simulating small particles of materials with and without the presence of gases. Computational chemistry has application in studying catalysis, properties of polymers, all of interest to various NASA missions, including those previously mentioned. In addition to discussing these applications of computational chemistry within NASA, the governing equations and the need for supercomputers for their solution is outlined.

This study was conducted with the participation of 688 nurses who worked at two university-affiliated hospitals. These nurses were chosen using a stratified random sampling method. The data were collected using the Multicomponent Assessment of Computer Literacy and the Pretest for Attitudes Towards Computers in Healthcare Assessment Scale v. 2. The nurses, in general, had positive attitudes towards computers, and their computer literacy was good. Computer literacy in general had significant positive correlations with individual elements of computer competency and with attitudes towards computers. If the computer is to be an effective and beneficial part of the health-care system, it is necessary to help nurses improve their computer competency. © 2014 Wiley Publishing Asia Pty Ltd.

Biological computations like electrocardiological modelling and simulation usually require high-performance computing environments. This paper introduces an implementation of parallel computation for computer simulation of electrocardiograms (ECGs) in a personal computer environment with an Intel CPU of Core (TM) 2 Quad Q6600 and a GPU of Geforce 8800GT, with software support by OpenMP and CUDA. It was tested in three parallelization device setups: (a) a four-core CPU without a general-purpose GPU, (b) a general-purpose GPU plus 1 core of CPU, and (c) a four-core CPU plus a general-purpose GPU. To effectively take advantage of a multi-core CPU and a general-purpose GPU, an algorithm based on load-prediction dynamic scheduling was developed and applied to setting (c). In the simulation with 1600 time steps, the speedup of the parallel computation as compared to the serial computation was 3.9 in setting (a), 16.8 in setting (b), and 20.0 in setting (c). This study demonstrates that a current PC with a multi-core CPU and a general-purpose GPU provides a good environment for parallel computations in biological modelling and simulation studies.

Demir, I.; Agliamzanov, R.

2014-12-01

Distributed volunteer computing can enable researchers and scientist to form large parallel computing environments to utilize the computing power of the millions of computers on the Internet, and use them towards running large scale environmental simulations and models to serve the common good of local communities and the world. Recent developments in web technologies and standards allow client-side scripting languages to run at speeds close to native application, and utilize the power of Graphics Processing Units (GPU). Using a client-side scripting language like JavaScript, we have developed an open distributed computing framework that makes it easy for researchers to write their own hydrologic models, and run them on volunteer computers. Users will easily enable their websites for visitors to volunteer sharing their computer resources to contribute running advanced hydrological models and simulations. Using a web-based system allows users to start volunteering their computational resources within seconds without installing any software. The framework distributes the model simulation to thousands of nodes in small spatial and computational sizes. A relational database system is utilized for managing data connections and queue management for the distributed computing nodes. In this paper, we present a web-based distributed volunteer computing platform to enable large scale hydrological simulations and model runs in an open and integrated environment.

Visual ergonomics and computer work--is it all about computer glasses?

Science.gov (United States)

Jonsson, Christina

2012-01-01

The Swedish Provisions on Work with Display Screen Equipment and the EU Directive on the minimum safety and health requirements for work with display screen equipment cover several important visual ergonomics aspects. But a review of cases and questions to the Swedish Work Environment Authority clearly shows that most attention is given to the demands for eyesight tests and special computer glasses. Other important visual ergonomics factors are at risk of being neglected. Today computers are used everywhere, both at work and at home. Computers can be laptops, PDA's, tablet computers, smart phones, etc. The demands on eyesight tests and computer glasses still apply but the visual demands and the visual ergonomics conditions are quite different compared to the use of a stationary computer. Based on this review, we raise the question if the demand on the employer to provide the employees with computer glasses is outdated.

Computers and the Internet have the potential to enrich the lives of seniors and aid in the performance of important tasks required for independent living. A prerequisite for reaping these benefits is having the skills needed to use these systems, which is highly dependent on proper training. One prerequisite for efficient and effective training is being able to gauge current levels of proficiency. We developed a new measure (the Computer Proficiency Questionnaire, or CPQ) to measure computer proficiency in the domains of computer basics, printing, communication, Internet, calendaring software, and multimedia use. Our aim was to develop a measure appropriate for individuals with a wide range of proficiencies from noncomputer users to extremely skilled users. To assess the reliability and validity of the CPQ, a diverse sample of older adults, including 276 older adults with no or minimal computer experience, was recruited and asked to complete the CPQ. The CPQ demonstrated excellent reliability (Cronbach's α = .98), with subscale reliabilities ranging from .86 to .97. Age, computer use, and general technology use all predicted CPQ scores. Factor analysis revealed three main factors of proficiency related to Internet and e-mail use; communication and calendaring; and computer basics. Based on our findings, we also developed a short-form CPQ (CPQ-12) with similar properties but 21 fewer questions. The CPQ and CPQ-12 are useful tools to gauge computer proficiency for training and research purposes, even among low computer proficient older adults. © The Author 2013.

Trends in absolute and relative educational inequalities in four modifiable ischaemic heart disease risk factors: repeated cross-sectional surveys from the Nord-Trøndelag Health Study (HUNT 1984–2008

Directory of Open Access Journals (Sweden)

Ernstsen Linda

2012-04-01

Full Text Available Abstract Background There has been an overall decrease in incident ischaemic heart disease (IHD, but the reduction in IHD risk factors has been greater among those with higher social position. Increased social inequalities in IHD mortality in Scandinavian countries is often referred to as the Scandinavian “public health puzzle”. The objective of this study was to examine trends in absolute and relative educational inequalities in four modifiable ischaemic heart disease risk factors (smoking, diabetes, hypertension and high total cholesterol over the last three decades among Norwegian middle-aged women and men. Methods Population-based, cross-sectional data from The Nord-Trøndelag Health Study (HUNT: HUNT 1 (1984–1986, HUNT 2 (1995–1997 and HUNT 3 (2006–2008, women and men 40–59 years old. Educational inequalities were assessed using the Slope Index of Inequality (SII and The Relative Index of Inequality (RII. Results Smoking prevalence increased for all education groups among women and decreased in men. Relative and absolute educational inequalities in smoking widened in both genders, with significantly higher absolute inequalities among women than men in the two last surveys. Diabetes prevalence increased in all groups. Relative inequalities in diabetes were stable, while absolute inequalities increased both among women (p = 0.05 and among men (p = 0.01. Hypertension prevalence decreased in all groups. Relative inequalities in hypertension widened over time in both genders. However, absolute inequalities in hypertension decreased among women (p = 0.05 and were stable among men (p = 0.33. For high total cholesterol relative and absolute inequalities remained stable in both genders. Conclusion Widening absolute educational inequalities in smoking and diabetes over the last three decades gives rise to concern. The mechanisms behind these results are less clear, and future studies are needed to assess if educational

Napier, T.M.

1978-01-01

The microprocessor-based system described is intended to monitor and record data from radiation detectors on an extended site, and can accept detector output pulse rates between zero and 900 pulses per second. The logger accumulates the total dose received at each detector, calculates the mean dose rate with a time constant of 93 sec, compares it with two user-settable alarm levels and generates alarm signals if either level is exceeded. It also provides a 12-channel analog output to permit continuous recording of the dose rates, a printed log, and a serial data output for remote dose rate display. A NORD-10 computer can be connected to read the status of the detectors and alert users to alarm conditions. This system could form the basis of a range of medium-speed data collection and processing instruments. (Auth.)

Basic information is presented on diagnostic systems used at nuclear power plants with PWR reactors. They include systems used at the Novovoronezh nuclear power plant in the USSR, at the Nord power plant in the GDR, the system developed at the Hungarian VEIKI institute, the system used at the V-1 nuclear power plant at Jaslovske Bohunice in Czechoslovakia and systems of the Rockwell International company used in US nuclear power plants. These diagnostic systems are basically founded on monitoring vibrations and noise, loose parts, pressure pulsations, neutron noise, coolant leaks and acoustic emissions. The Rockwell International system represents a complex unit whose advantage is the on-line evaluation of signals which gives certain instructions for the given situation directly to the operator. The other described systems process signals using similar methods. Digitized signals only serve off-line computer analyses. (Z.M.)

Full Text Available In today’s job market, computer skills are part of the prerequisites for many jobs. In this paper, we report on a study of readiness to work with computers (the dependent variable among unemployed women (N=54 after participating in a unique, web-supported training focused on computer skills and empowerment. Overall, the level of participants’ readiness to work with computers was much higher at the end of the course than it was at its begin-ning. During the analysis, we explored associations between this variable and variables from four categories: log-based (describing the online activity; computer literacy and experience; job-seeking motivation and practice; and training satisfaction. Only two variables were associated with the dependent variable: knowledge post-test duration and satisfaction with content. After building a prediction model for the dependent variable, another log-based variable was highlighted: total number of actions in the course website along the course. Overall, our analyses shed light on the predominance of log-based variables over variables from other categories. These findings might hint at the need of developing new assessment tools for learners and trainees that take into consideration human-computer interaction when measuring self-efficacy variables.

2005-01-01

The book "Computational Error and Complexity in Science and Engineering” pervades all the science and engineering disciplines where computation occurs. Scientific and engineering computation happens to be the interface between the mathematical model/problem and the real world application. One needs to obtain good quality numerical values for any real-world implementation. Just mathematical quantities symbols are of no use to engineers/technologists. Computational complexity of the numerical method to solve the mathematical model, also computed along with the solution, on the other hand, will tell us how much computation/computational effort has been spent to achieve that quality of result. Anyone who wants the specified physical problem to be solved has every right to know the quality of the solution as well as the resources spent for the solution. The computed error as well as the complexity provide the scientific convincing answer to these questions. Specifically some of the disciplines in which the book w...

Yet the use of computational tools is almost absent in the study of religion. Given that religion is a cluster of interrelated phenomena and that research...... concerning these phenomena should strive for multilevel analysis, this article argues that the computational approach offers new methodological and theoretical opportunities to the study of religion. We argue that the computational approach offers 1.) an intermediary step between any theoretical construct...... and its targeted empirical space and 2.) a new kind of data which allows the researcher to observe abstract constructs, estimate likely outcomes, and optimize empirical designs.

2013-01-01

Background Survey response rates have been declining over the past decade. The more widespread use of the Internet and Web-based technologies among potential health survey participants suggests that Web-based questionnaires may be an alternative to paper questionnaires in future epidemiological studies. Objective To compare response rates in a population of parents by using 4 different modes of data collection for a questionnaire survey of which 1 involved a nonmonetary incentive. Methods A random sample of 3148 parents of Danish children aged 2-17 years were invited to participate in the Danish part of the NordChild 2011 survey on their children’s health and welfare. NordChild was conducted in 1984 and 1996 in collaboration with Finland, Iceland, Norway, and Sweden using mailed paper questionnaires only. In 2011, all countries used conventional paper versions only except Denmark where the parents were randomized into 4 groups: (1) 789 received a paper questionnaire only (paper), (2) 786 received the paper questionnaire and a log-in code to the Web-based questionnaire (paper/Web), (3) 787 received a log-in code to the Web-based questionnaire (Web), and (4) 786 received log-in details to the Web-based questionnaire and were given an incentive consisting of a chance to win a tablet computer (Web/tablet). In connection with the first reminder, the nonresponders in the paper, paper/Web, and Web groups were also present with the opportunity to win a tablet computer as a means of motivation. Descriptive analysis was performed using chi-square tests. Odds ratios were used to estimate differences in response rates between the 4 modes. Results In 2011, 1704 of 3148 (54.13%) respondents answered the Danish questionnaire. The highest response rate was with the paper mode (n=443, 56.2%). The other groups had similar response rates: paper/Web (n=422, 53.7%), Web (n=420, 53.4%), and Web/tablet (n=419, 53.3%) modes. Compared to the paper mode, the odds for response rate in the

Startzman, R.A.

1994-01-01

While computing is applied widely in the production segment of the petroleum industry, its effective application is the primary goal of computing management. Computing technology has changed significantly since the 1950's, when computers first began to influence petroleum technology. The ability to accomplish traditional tasks faster and more economically probably is the most important effect that computing has had on the industry. While speed and lower cost are important, are they enough? Can computing change the basic functions of the industry? When new computing technology is introduced improperly, it can clash with traditional petroleum technology. This paper examines the role of management in merging these technologies

Blind quantum computation (BQC) allows a client who has only limited quantum power to achieve quantum computation with the help of a remote quantum server and still keep the client's input, output, and algorithm private. Recently, Kashefi and Wallden extended BQC to achieve two-party quantum computation which allows two parties Alice and Bob to perform a joint unitary transform upon their inputs. However, in their protocol Alice has to prepare rotated single qubits and perform Pauli operations, and Bob needs to have a powerful quantum computer. In this work, we also utilize the idea of BQC to put forward an improved two-party quantum computation protocol in which the operations of both Alice and Bob are simplified since Alice only needs to apply Pauli operations and Bob is just required to prepare and encrypt his input qubits.
