    The present study deals with dissipative future universe without big rip in context of Eckart formalism. The generalised chaplygin gas, characterised by equaction of state $p=-\\frac{A}{\\rho^\\frac{1}{\\alpha}}$, has been considered as a model for dark energy due to its dark-energy-like evolution at late time. It is demonstrated that, if the cosmic dark energy behaves like a fluid as well as chaplygin gas simultaneously then the big rip problem does not arise and the scale factor is found to be regular for all time.

    Giving the opening keynote speech at last year's Healthcare Estates conference, Mike Hobbs, managing director of Carillion Health, drew on his 25 years' experience to discuss how innovation can help drive the greater efficiency and productivity that the NHS is charged with delivering, in the process cutting costs at a time when the service faces the tightest economic pressures in its history. He argued that as we enter a new world of 'Big data', the availability of accurate, comprehensive data on which to base key decisions will be the major enabler for the design and construction of high quality healthcare facilities in the future. It will equally be key, he said, to their efficient, low-cost, and optimal utilisation to provide the higher 'productivity' the Government says is essential. PMID:27132307

  8. Interoperability Outlook in the Big Data Future

    The establishment of distributed active archive centers (DAACs) as data warehouses and the standardization of file format by NASA's Earth Observing System Data Information System (EOSDIS) had doubtlessly propelled interoperability of NASA Earth science data to unprecedented heights in the 1990s. However, we obviously still feel wanting two decades later. We believe the inadequate interoperability we experience is a result of the the current practice that data are first packaged into files before distribution and only the metadata of these files are cataloged into databases and become searchable. Data therefore cannot be efficiently filtered. Any extensive study thus requires downloading large volumes of data files to a local system for processing and analysis.The need to download data not only creates duplication and inefficiency but also further impedes interoperability, because the analysis has to be performed locally by individual researchers in individual institutions. Each institution or researcher often has its/his/her own preference in the choice of data management practice as well as programming languages. Analysis results (derived data) so produced are thus subject to the differences of these practices, which later form formidable barriers to interoperability. A number of Big Data technologies are currently being examined and tested to address Big Earth Data issues. These technologies share one common characteristics: exploiting compute and storage affinity to more efficiently analyze large volumes and great varieties of data. Distributed active "archive" centers are likely to evolve into distributed active "analysis" centers, which not only archive data but also provide analysis service right where the data reside. "Analysis" will become the more visible function of these centers. It is thus reasonable to expect interoperability to improve because analysis, in addition to data, becomes more centralized.

    Rapid growth in the amount of data that is electronically recorded as part of routine clinical operations has generated great interest in the use of Big Data methodologies to address clinical and research questions. These methods can efficiently analyze and deliver insights from high-volume, high-variety, and high-growth rate datasets generated across the continuum of care, thereby forgoing the time, cost, and effort of more focused and controlled hypothesis-driven research. By virtue of an existing robust information technology infrastructure and years of archived digital data, radiology departments are particularly well positioned to take advantage of emerging Big Data techniques. In this review, we describe four areas in which Big Data is poised to have an immediate impact on radiology practice, research, and operations. In addition, we provide an overview of the Big Data adoption cycle and describe how academic radiology departments can promote Big Data development. PMID:26683510

    "Big data" is a new buzzword. The point is not to be dazzled by the volume of data, but rather to analyze it, and convert it into insights, innovations, and business value. There are also real differences between conventional analytics and big data. In this article, we show some results of big data analysis using open DPC (Diagnosis Procedure Combination) data in areas of the central part of JAPAN: Toyama, Ishikawa, Fukui, Nagano, Gifu, Aichi, Shizuoka, and Mie Prefectures. These 8 prefectures contain 51 medical administration areas called the second medical area. By applying big data analysis techniques such as k-means, hierarchical clustering, and self-organizing maps to DPC data, we can visualize the disease structure and detect similarities or variations among the 51 second medical areas. The combination of a big data analysis technique and open DPC data is a very powerful method to depict real figures on patient distribution in Japan. PMID:27363223

  18. Meeting overlay requirements for future technology nodes with in-die overlay metrology

    As a consequence of the shrinking sizes of the integrated circuit structures, the overlay budget shrinks as well. Overlay is traditionally measured with relatively large test structures which are located in the scribe line of the exposure field, in the four corners. Although the performance of the overlay metrology tools has improved significantly over time it is questionable if this traditional method of overlay control will be sufficient for future technology nodes. For advanced lithography techniques like double exposure or double patterning, in-die overlay is critical and it is important to know how much of the total overlay budget is consumed by in-die components. We reported earlier that small overlay targets were included directly inside die areas and good performance was achieved. This new methodology enables a wide range of investigations. This provides insight into processes which were less important in the past or not accessible for metrology. The present work provides actual data from productive designs, instead of estimates, illustrating the differences between the scribe line and in-die registration and overlay. The influence of the pellicle on pattern placement on mask and wafer overlay is studied. Furthermore the registration overlay error of the reticles is correlated to wafer overlay residuals. The influence of scanner-induced distortions (tool to tool differences) on in-die overlay is shown. Finally, the individual contributors to in-die-overlay are discussed in the context of other overlay contributors. It is proposed to use in-die overlay and registration results to derive guidelines for future overlay and registration specifications. It will be shown that new overlay correction schemes which take advantage of the additional in-die overlay information need to be considered for production.

    We live in the era of genomics and big data. Evaluating the impact on health of large-scale biological, social, and environmental data is an emerging challenge in the field of epidemiology. In the past 3 years, major discussions and plans for the future of epidemiology, including with several recommendations for actions to transform the field, have been launched by 2 institutes within the National Institutes of Health. In the present commentary, I briefly explore the themes of these recommendations and their effects on leadership, resources, cohort infrastructure, and training. Ongoing engagement within the epidemiology community is needed to determine how to shape the evolution of the field and what truly matters for changing population health. We also need to assess how to leverage existing epidemiology resources and develop new studies to improve human health. Readers are invited to examine these recommendations, consider others that might be important, and join in the conversation about the future of epidemiology. PMID:26628513

    The aim of this paper is to present the state of the science concerning issues in end-of-life (EOL) care which have an impact on intensive care nurses possibilities to provide nursing care for dying patients and their families. The perspective of families is also illuminated and finally ethical challenges in the present and for the future are discussed. The literature review revealed that the problem areas nurses report concerning EOL care have been the same over three decades. Most problems are related to inter-disciplinary collaboration and communication with the medical profession about the transition from cure to comfort care. Nurses need enhanced communication skills in their role as the patient's advocate. Education in EOL care and a supportive environment are prerequisites for providing EOL care. Losing a loved one in the ICU is a stressful experience for close relatives and nursing care has a profound impact on families' memories of the EOL care given to their loved ones. It is therefore important that ICU nurses are aware of families' needs when a loved one is dying and that follow-up services are appreciated by bereaved family members. Ethical challenges are related to changed sedation practices, organ donation, globalisation and cultural sensitivity. PMID:25218688

    To survive competition in the heat market without state subsidies, district heating needs new marketing strategies and instruments as well as new management and corporate structures. Marketing means market-related thinking, -deciding and -acting. The consumer is the central point of approach and ultimately justification for the existence of the company. Marketing is a style of management, an orientation of the company to the market, which permeate the entire company. The factor customer satisfaction must be given priority in all corporate sectors, in order to create close customer contact externally by customer orientation internally. There is a range of new concepts designed to make internal structures and procedures leaner and more flexible. Flexibility is demanded to guarantee the required customer orientation towards both the inside and outside. To achieve this, companies need pan-divisional, process-oriented teams which control themselves on the basis of set goals. Responsibility is channelled down to the point of application, meaning that intensive and direct communication within the teams themselves and to the next hierarchy is vital. Becoming better, more flexible, more cost-conscious and faster are the goals which employees must themselves develop and maintain.

    The intense competition that accompanied the growth of internet-based companies ushered in the era of 'big data' characterized by major innovations in processing of very large amounts of data and the application of advanced analytics including data mining and machine learning. Healthcare is on the cusp of its own era of big data, catalyzed by the changing regulatory and competitive environments, fueled by growing adoption of electronic health records, as well as efforts to integrate medical claims, electronic health records and other novel data sources. Applying the lessons from big data pioneers will require healthcare and life science organizations to make investments in new hardware and software, as well as in individuals with different skills. For life science companies, this will impact the entire pharmaceutical value chain from early research to postcommercialization support. More generally, this will revolutionize comparative effectiveness research. PMID:24645690

  14. Big data and tactical analysis in elite soccer: future challenges and opportunities for sports science.

    Rein, Robert; Memmert, Daniel

    2016-01-01

    Until recently tactical analysis in elite soccer were based on observational data using variables which discard most contextual information. Analyses of team tactics require however detailed data from various sources including technical skill, individual physiological performance, and team formations among others to represent the complex processes underlying team tactical behavior. Accordingly, little is known about how these different factors influence team tactical behavior in elite soccer. In parts, this has also been due to the lack of available data. Increasingly however, detailed game logs obtained through next-generation tracking technologies in addition to physiological training data collected through novel miniature sensor technologies have become available for research. This leads however to the opposite problem where the shear amount of data becomes an obstacle in itself as methodological guidelines as well as theoretical modelling of tactical decision making in team sports is lacking. The present paper discusses how big data and modern machine learning technologies may help to address these issues and aid in developing a theoretical model for tactical decision making in team sports. As experience from medical applications show, significant organizational obstacles regarding data governance and access to technologies must be overcome first. The present work discusses these issues with respect to tactical analyses in elite soccer and propose a technological stack which aims to introduce big data technologies into elite soccer research. The proposed approach could also serve as a guideline for other sports science domains as increasing data size is becoming a wide-spread phenomenon. PMID:27610328

    Full Text Available The explosion of the data both in the biomedical research and in the healthcare systems demands urgent solutions. In particular, the research in omics sciences is moving from a hypothesis-driven to a data-driven approach. Healthcare is additionally always asking for a tighter integration with biomedical data in order to promote personalized medicine and to provide better treatments. Efficient analysis and interpretation of Big Data opens new avenues to explore molecular biology, new questions to ask about physiological and pathological states, and new ways to answer these open issues. Such analyses lead to better understanding of diseases and development of better and personalized diagnostics and therapeutics. However, such progresses are directly related to the availability of new solutions to deal with this huge amount of information. New paradigms are needed to store and access data, for its annotation and integration and finally for inferring knowledge and making it available to researchers. Bioinformatics can be viewed as the “glue” for all these processes. A clear awareness of present high performance computing (HPC solutions in bioinformatics, Big Data analysis paradigms for computational biology, and the issues that are still open in the biomedical and healthcare fields represent the starting point to win this challenge.

    Great progress has been made in the exploration and production of natural gas in recent years. Reserves of conventional gas are plentiful, and large resources of unconventional gas have been added. At the same time, there is still a lot of pressure for climate action to reduce greenhouse gas emissions. Natural gas is the lowest-carbon fossil fuel. Almost all medium- to long-term energy scenarios foresee a substantial increase in global consumption of natural gas. It can be used to generate both power and heat. But so far gaseous fuels have had only a niche position as an option for the transport sector. Increased discussion of gas, in particular natural gas, as a future transport fuel started just recently. The following article starts by considering the development of supply and current expectations for availability of natural gas. It discusses the various types of gas, in particular conventional and unconventional, and technical methods both standard and new for gas production. It also deals with natural gas demand scenarios and future markets, including the value chain for natural gas fuels. The article covers in particular the use of gaseous and gas-based fuels in the transport sector. It examines various production paths for natural gas fuels for transport, and also the fuels as such (CNG, LNG, GTL); it compares the product characteristics of natural gas fuels with those of conventional fuels (gasoline / diesel fuel) and other gaseous fuels (in particular LPG and hydrogen). It discusses the application possibilities of gas fuels in the various transport sectors. It considers the use of gas fuels in internal combustion engines in different transport sectors with different combustion processes, including consideration of their energy efficiency (consumption / performance) and their ecological performance (air pollutants and greenhouse gas emissions). Finally, it addresses the question of what and under what conditions natural gas fuels can contribute to an &apos

    What means a sustainable energy sector? The advancement of innovative technologies to decrease the dependency of fossil, dwindling fuels and the prevention of greenhouse gases? Sure. Is in Germany to this topic really volition of policy and economy? The answer should be: partly. Renewable Energies are in a continued increase due to the Renewable Energy Sources Act, the fuel cell is in contrast an ineffectual initiative, the hold on the nuclear industry is a return to the last century. Fuel cells are one of the technologies with the greatest potential: Whether for the home-supply, for industry- or mobile applications (e-mobility), fuel cells are perfect heat- and electricity plants, scalable for a large power range. In conjunction with the supply of pure- or chemical bounded hydrogen by renewable energies, fuel cells could be the plants of the future. Finally the technology must be controlled. This occurred constricted, there is (yet) no durability and cost effectiveness given. Here it is the challenge of the policy, the r and d and the industry respectively the manufacturers to develop this technology to marketability with the help of target-oriented research programs and subsidies or to fail.

    Full Text Available [english] Medical education is presently unveiling trends, which also dominate other fields of higher education. Within the framework of internationalisation and globalisation, and driven by developments in information and communication technology and the pronounced migration of medical doctors, one has observed consequences such as commercialisation and privatisation. This, in turn, has engendered a quality assurance reaction with focus on standardisation and accreditation. The Bologna Declaration and Process can be seen as part of this new quality concern, but also raises problems for medical education regarding the two-cycle (bachelor and master degrees system. Standard setting in medical education in Europe took its start with the EU Medical Directive, which has essentially not been changed in 30 years. The increasing internationalisation of medical education, which shows a number of innovative trends, but which also unveils many problems and challenges, emphasises the role of the WFME Global Standards Programme launched in 1997. The Trilogy of Global Standards, covering the continuum of medical education, has been adopted in all parts of the world. The Standards for Basic Medical Education are used in reform programmes in many medical schools and are now also being incorporated in definition of national accreditation standards. This development has recently been strengthened in the WHO/WFME Strategic Partnership to Improve Medical Education. One practical result of this collaboration was the development of WHO/WFME Guidelines for Accreditation of Basic Medical Education. A Task Force under the new EU Thematic Network MEDINE is now working with definition of European accreditation standards using the WFME Global Standards as a template. The immediate perspective will be establishment of national accreditation systems in the European region and there is probably no need at the moment for a common accreditation system in Europe.

    The third Ministerial Conference of the World Trade Organisation (WTO) took place in Seattle (USA) from November 30{sup th} to December 3{sup rd} 1999. WTO members failed to agree on an agenda for a new round of trade-negotiation that should also include environmental and sustainability aspects. The Seattle Ministerial Conference provoked massive protests from non-governmental organisations (NGO) dealing with environment and development issues. They see the GATT/WTO regime - and globalisation in general - as a threat to their concerns. Against this background, the study analyses possibilities for the integration of environmental and sustainability aspects into upcoming WTO-negotiations. The focus is on views and proposals from international NGOs and critical scientists. First, the study deals with current and potential future areas of conflicts between environmental and trade policies. Furthermore, the environmental aspects of trade liberalisation in specific sectors and regulatory fields are discussed, which are currently negotiated in the WTO (agriculture, services) or which should be included in further negotiations (forest products, investment, etc.). The study moves on to an account of the WTO-Conference in Seattle from an environmental perspective and demonstrate a multitude of factors contributed to the failure of the conference. (orig.)

    The emergence of massive datasets in a clinical setting presents both challenges and opportunities in data storage and analysis. This so called "big data" challenges traditional analytic tools and will increasingly require novel solutions adapted from other fields. Advances in information and communication technology present the most viable solutions to big data analysis in terms of efficiency and scalability. It is vital those big data solutions are multithreaded and that data access approaches be precisely tailored to large volumes of semi-structured/unstructured data. THE MAPREDUCE PROGRAMMING FRAMEWORK USES TWO TASKS COMMON IN FUNCTIONAL PROGRAMMING: Map and Reduce. MapReduce is a new parallel processing framework and Hadoop is its open-source implementation on a single computing node or on clusters. Compared with existing parallel processing paradigms (e.g. grid computing and graphical processing unit (GPU)), MapReduce and Hadoop have two advantages: 1) fault-tolerant storage resulting in reliable data processing by replicating the computing tasks, and cloning the data chunks on different computing nodes across the computing cluster; 2) high-throughput data processing via a batch processing framework and the Hadoop distributed file system (HDFS). Data are stored in the HDFS and made available to the slave nodes for computation. In this paper, we review the existing applications of the MapReduce programming framework and its implementation platform Hadoop in clinical big data and related medical health informatics fields. The usage of MapReduce and Hadoop on a distributed system represents a significant advance in clinical big data processing and utilization, and opens up new opportunities in the emerging era of big data analytics. The objective of this paper is to summarize the state-of-the-art efforts in clinical big data analytics and highlight what might be needed to enhance the outcomes of clinical big data analytics tools.

    Full Text Available The main objective of this contribution is to examine the developments and challenges of African Studies in Poland, with a special focus on the fields of political science and economics. The article demonstrates that the historical development of Polish African Studies has shaped, but also limited, the ongoing debate concerning its nature and objectives. The paper discusses two competing interpretations of the substance of African Studies and deals with the current challenges and hopes of the Polish academic community studying Africa. It argues that while the field of African Studies usually serves as a common denominator and a type of “area” platform where various scholars doing research on Africa can share their findings, this does not necessarily lead to integration within the community and/or to better communication. Quite paradoxically, the diagnosis of Polish African Studies presented almost 50 years ago by Jan Halpern can still be applied today: “Generally speaking, Polish scholars in African subjects feel that the further progress of their work demands, above all, a better coordination of research and closer contact with specialists abroad.”Dieser Beitrag widmet sich der Entwicklung der Afrikaforschung in Polen und den Herausforderungen, vor denen sie steht, unter besonderer Berücksichtigung der Politik- und Wirtschaftswissenschaft.

    Full Text Available Using the metaphor of the elephant and the three blind men, this paper discusses some elements of the scholarly debate on the postcolonial turn in academia, in and of Africa, and in anthropology in particular. It is a part of the context in which anthropology remains unpopular among many African intellectuals. How do local knowledge practices take up existential issues and epistemological perspectives that may interrogate and enrich more global transcultural debates and scholarly reflexivity? Many an anthropologist still resists opening his or her mind up to life-worlds unfolding themselves through the interplay between everyday practice and the manifold actions and messages of humans, ancestors and non-human agents in sites of emerging meaning-production and innovative world-making. African anthropologists seeking recognition find themselves contested or dismissed by fellow anthropologists for doing “native”, “self” or “insider” anthropology, and are sometimes accused of perpetuating colonial epistemologies and subservience by fellow African scholars who are committed to scholarship driven by the need to valorise ways of being and knowing endogenous to Africa. This essay calls on anthropologists studying Africa to reflect creative diversity and reflexivity in the conceptualisation and implementation of research projects, as well as in how they provide for co-production, collaboration and co-implication within anthropology across and beyond disciplines.Unter Rückgriff auf die Fabel vom Elefanten und den drei weisen Männern diskutiert dieser Beitrag einige Elemente der Debatte zur postkolonialen Wende in der Wissenschaft – innerhalb und außerhalb Afrikas und insbesondere in Bezug auf die Ethnologie.

    This paper provides an overview of recent developments in big data in the context of biomedical and health informatics. It outlines the key characteristics of big data and how medical and health informatics, translational bioinformatics, sensor informatics, and imaging informatics will benefit from an integrated approach of piecing together different aspects of personalized information from a diverse range of data sources, both structured and unstructured, covering genomics, proteomics, metabolomics, as well as imaging, clinical diagnosis, and long-term continuous physiological sensing of an individual. It is expected that recent advances in big data will expand our knowledge for testing new hypotheses about disease management from diagnosis to prevention to personalized treatment. The rise of big data, however, also raises challenges in terms of privacy, security, data ownership, data stewardship, and governance. This paper discusses some of the existing activities and future opportunities related to big data for health, outlining some of the key underlying issues that need to be tackled. PMID:26173222

    Full Text Available [english] The consideration of gender aspects in clinical routine is of high importance towards an individualized patient care and a starting point of diversity medicine. Gender-specific awareness is an indispensable basis for an optimized medical treatment. A current study at the medical faculties of Muenster and Duisburg-Essen University (Germany revealed an insufficient knowledge among students and lecturers in this area. An interdisciplinary, international workshop took place in Muenster (Germany in May 2012 on the topic how to integrate gender aspects into medical curricula in the future aiming at a better health care for both sexes in long term. This position paper summarizes the conclusions. It was suggested to teach gender-specific contents from the first semester comprehensively – using standardized definitions and a gender-neutral language, since it is crucial not to increase the students’ workload any further. The key to success is to implement gender aspects by using meaningful examples on a regular basis – ideally in a longitudinal manner. The content of teaching should be selected by the lecturers and full professors and be considered within students´ exams. To reach these goals, an absolute support of the respective medical faculties as well as the integration of these gender-specific learning objectives into the national competence-based learning catalogue for medical education (NKLM is obligatory.[german] Die Berücksichtigung von Geschlechteraspekten im klinischen Alltag ist ein wichtiger Schritt auf dem Weg zu passgenauer Medizin und der Beginn einer.Kenntnisse über geschlechtersensible Aspekte in der Medizin sind eine essentielle Grundlage für eine optimale PatientInnenversorgung.

    Full Text Available Die onderwerp, "Die vrou in die kerkgeskiedenis” is so veelsydig as die lewe self en die eerste vraag wat opduik is: "Waar begin die kerkgeskiedenis?” Daaroor het in boeke wat in die dertigerjare van hierdie eeu geskryf is, geen eenstemmigheid geheers nie. In ’n beknopte geskiedenis van wat Spoelstra vir katkisante geskryf het, verduidelik hy dat die kerkgeskiedenis by Adam en Eva begin, terwyl in hul "Kerkgeskiedenis vir ons Volk” A. M. Kriel en G. B. A. Gerdener skryf dat die kerkgeskiedenis op die Pinksterdag begin. (Hiermee stem S. du Toit asook Spoelstra, Pont en Keet  saam. G. S. Wegener sê in "Die Lewende Kerk” dat dit op Golgotha "in vertwyfeling, wanhoop en vrees” begin. Maar nou wil ek as "leek” en miskien as "ketter” van al hierdie geleerde uitsprake verskil. Vir my begin die kerkgeskiedenis met die opstanding van Christus uit die graf, toe Hy volgens Job. 20:7 aan Maria gesê het: "Gaan na my broeders en sê vir hulle: "Ek vaar op na my Vader en julle Vader en na my God en julle God”.

  7. Turning the big knob: an evaluation of the use of energy policy to modulate future climate impacts

    International Nuclear Information System (INIS)

    Conventional wisdom on climate change policy is straightforward: reducing greenhouse gas emissions will avoid the increased frequency and magnitude of climate impacts on environment and society that might occur if emissions are not controlled. The proponents of conventional wisdom widely consider energy policy to be the main policy tool available to decision makers to intentionally modulate future climate impacts. In this paper we challenge the notion that policy makers should intentionally use energy policy to modulate future climate impacts. The paper argues that policy makers may well make large changes in energy policy (and future emissions) without significantly affecting future climate impacts. In other words, even if a theoretical case could be made that energy policy could be used intentionally to modulate future climate, other factors will play a larger role in creating future impact.y and are arguably more amenable to policy change. To illustrate this conclusion, the paper presents a sensitivity analysis under the assumptions of the Intergovernmental Panel on Climate Change for the case of tropical cyclones. One implication of the paper's conclusions is that policy responses to extreme weather events should be decoupled from considerations of energy policy. This decoupling is not intended to diminish either the importance of responding to climate change or of energy policy. Rather, it is to emphasise that there are many responses under the rubric of adaptation that could play a much greater role in reducing societal vulnerability to losses. One of the implications of this change is that scientific uncertainty need not stand in the way of effective action because the measures proposed make sense under any future climate scenario.

    Driven by environmental and political concerns, biofuels shall attain an increasing importance in the future. Some forecasts see these fuels contributing up to 50 % of the global fuel demand by the middle of the century. The aim of this article is to discuss these scenarios regarding the aspects of sustainability and to compare the different kinds of production of biogenic fuels. In contrast to those of the first and second generation, third generation biofuels, which are based on specifically cultivated plants and micro-organisms, do not stand in competition to the production of food and have a distinctly lower requirement of agricultural land use. These fuels are supposed to present a clearly better profile of sustainability. While further research and development is required during the next years before they can contribute to the fuel supply to a bigger extent, they nevertheless have the potential to make a significant contribution to an environmentally protective and sustainable mobility in the future.

    In 2007, the enercity Netzgesellschaft mbH (eNG), the grid company Stadtwerke Hannover AG, commissioned a study on the development of heat demand in the urban area of Hanover till to 2050 at the Institute for Design and Engineering at the Leibniz University Hanover. The study began with a representative sample survey of the building insulation standards. Then the current and future expected demand for heat is documented together with other important structural data in a comprehensive database based on individual buildings. In conjunction with a building typology for residential and non-residential buildings the future development of the heat demand was estimated in two scenarios. The result is clear, the demand for heat decreases dramatically. In the conservativing TREND scenario, i.e. without additional climate protection efforts in the future, the demand for heat decreases to nearly 72 % relative to 2005, with increased climate protection efforts (SPAR scenario) to 45 %. Today's housing stock offers the greatest potential for energy savings. Commercial buildings are clearly subordinated. Thus, the heat atlas is an excellent basis for strategic planning such as an optimization of a parallel supply with gas heating and district heating.

    Intelligent energy-efficient buildings, ideally designed within an overall context of ''smarter cities'' organised for sustainability, are destined to be part of our future. They play an integral role in solution approaches to the new energy era, resource conservation and an improvement of living conditions. And they can already be cost-effective today. This is illustrated with an application example from Southern Germany, where, at the headquarters of a large corporation, tomorrow's smart energy solutions have already become a reality thanks to clever management and the use of existing IT equipment.

  14. Quality and impact assessment in new geoscience communication : future perspectives through digital communication and Big Data exploration techniques

    Science.gov (United States)

    Vicari, Rosa; Schertzer, Daniel; Deutsch, Jean-Claude; Moilleron, Regis

    2015-04-01

    Since 1990s up to now, climate and environmental science communication has gradually become a priority of policy programmes, a consolidated subject of training and education, a developed and greatly expanded field of professional practices. However, in contrast to this very fast evolution there is presumably a deficit in terms of research and reflection on objective tools to assess the quality and impact of communication activities. The quality of communication in the field of science has become more and more challenging due to the fact that the role of traditional mediators (e.g. well reputed newspapers or broadcasters, science museums), that used to be considered quality guarantors, has now become marginal. Today, a new generation of communication professionals tend to be employed by research institutes to respond to a stronger request to develop accountable research projects, to increase transparency and trust and to disseminate and implementation of research findings. This research aims to understand how communication strategies, addressed to the general public, can optimise the impact of research findings in hydrology for resilient cities. The research will greatly benefit from the development of automated analysis of unstructured Big Data that allows the exploration of huge amounts of digital communication data: blogs, social networks postings, public speeches, press releases, publications, articles... Furthermore, these techniques facilitate the crossing of socio-economic and physical-environmental data and possibly lead to the identification of existing correlations. Case studies correspond to those of several research projects under the umbrella of the Chair "Hydrology for resilient cities" aimed to develop and test new solutions in urban hydrology that will contribute to the resilience of our cities to extreme weather. This research was initiated in the framework of the Interreg IVB project RAINGAIN and pursued in the project Blue Green Dream of the EU

    The vision for future identification systems is the comprehensive storage of all information about an item on the item itself. This information includes among others the bill of materials, the construction plans, instructions for use, the item's history - in short: the item's life story or biography from production to disposal. The usage of this information in the production process allows for a complete decentralisation of the automation, a gapless production record stored on the object itself, and with it an easier tracking and tracing of items in case of defects. Smart identification systems lay the foundation stone for visionary concepts as self-controlling and self-optimising production processes. (orig.)

    Cyanobacteria are among the first microorganisms to have inhabited the Earth. Throughout the last few billion years, they have played a major role in shaping the Earth as the planet we live in, and they continue to play a significant role in our everyday lives. Besides being an essential source of atmospheric oxygen, marine cyanobacteria are prolific secondary metabolite producers, often despite the exceptionally small genomes. Secondary metabolites produced by these organisms are diverse and complex; these include compounds, such as pigments and fluorescent dyes, as well as biologically-active compounds with a particular interest for the pharmaceutical industry. Cyanobacteria are currently regarded as an important source of nutrients and biofuels and form an integral part of novel innovative energy-efficient designs. Being autotrophic organisms, cyanobacteria are well suited for large-scale biotechnological applications due to the low requirements for organic nutrients. Recent advances in molecular biology techniques have considerably enhanced the potential for industries to optimize the production of cyanobacteria secondary metabolites with desired functions. This manuscript reviews the environmental role of marine cyanobacteria with a particular focus on their secondary metabolites and discusses current and future developments in both the production of desired cyanobacterial metabolites and their potential uses in future innovative projects.

    In order to meet the new powertrain requirements, Daimler AG is working not only to advance the combustion engine, but also to leverage all future technologies such as the electric drive, battery, and fuel cell. In the short to mid term, however, it is the combustion engine that will remain in the lead assuming that efficiency continues to improve. By reducing internal friction, up to 25 percent of losses can be mitigated during partial-load operation, which spotlights friction as a variable that cannot be overlooked. Motivated by this knowledge, Daimler has developed NANOSLIDE for cylinder liners, a technology that is capable of reducing friction in the piston assembly by up to 50 percent. In practical terms, this corresponds to a CO{sub 2} savings potential of 3 percent for a V6 diesel engine. The effects of friction-reducing measures have been demonstrated by referring to the M 276 V6 gasoline engine, which not only exhibit better performance with respect to the FEV tolerance band, but also optimized friction levels that, in total, are up to 31 percent lower than those of the predecessor engines. In addition to providing higher torque and output as well as complying with emissions requirements, these engines also consume up to 24 percent less fuel. The total gains achieved by integrating friction-reducing measures thus play an important role in characterizing the major advancements that have recently been made to reduce fuel consumption and set the stage for tomorrow's engines.

    The increasing availability and growth rate of biomedical information, also known as 'big data', provides an opportunity for future personalized medicine programs that will significantly improve patient care. Recent advances in information technology (IT) applied to biomedicine are changing the landscape of privacy and personal information, with patients getting more control of their health information. Conceivably, big data analytics is already impacting health decisions and patient care; however, specific challenges need to be addressed to integrate current discoveries into medical practice. In this article, I will discuss the major breakthroughs achieved in combining omics and clinical health data in terms of their application to personalized medicine. I will also review the challenges associated with using big data in biomedicine and translational science. PMID:24183925

    Well-designed astronomical surveys are powerful and have consistently been keystones of scientific progress. The Byurakan Surveys using a Schmidt telescope with an objective prism produced a list of about 3000 UV-excess Markarian galaxies but these objects have stimulated an enormous amount of further study and appear in over 16,000 publications. The CFHT Legacy Surveys used a wide-field imager to cover thousands of square degrees and those surveys are mentioned in over 1100 publications since 2002. Both ground and space-based astronomy have been increasing their investments in survey work. Survey instrumentation strives toward fair samples and large sky coverage and therefore strives to produce massive datasets. Thus we are faced with the "big data" problem in astronomy. Survey datasets require specialized approaches to data management. Big data places additional challenging requirements for data management. If the term "big data" is defined as data collections that are too large to move then there are profound implications for the infrastructure that supports big data science. The current model of data centres is obsolete. In the era of big data the central problem is how to create architectures that effectively manage the relationship between data collections, networks, processing capabilities, and software, given the science requirements of the projects that need to be executed. A stand alone data silo cannot support big data science. I'll describe the current efforts of the Canadian community to deal with this situation and our successes and failures. I'll talk about how we are planning in the next decade to try to create a workable and adaptable solution to support big data science.

    Our universe was born billions of years ago in a hot, violent explosion of elementary particles and radiation - the big bang. What do we know about this ultimate moment of creation, and how do we know it? Drawing upon the latest theories and technology, this new edition of The big bang, is a sweeping, lucid account of the event that set the universe in motion. Joseph Silk begins his story with the first microseconds of the big bang, on through the evolution of stars, galaxies, clusters of galaxies, quasars, and into the distant future of our universe.

    Many people hold a vision that big data will provide big insights and have a big impact in the future, and big-data-assisted scientific discovery is seen as an emerging and promising scientific paradigm. However, how to turn big data into deep insights with tremendous value still remains obscure. To meet the challenge, universal knowledge discovery from big data (UKD) is proposed. The new concept focuses on discovering universal knowledge, which exists in the statistical analyses of big data ...

    Full Text Available [english] Since several years risk-based monitoring is the new “magic bullet” for improvement in clinical research. Lots of authors in clinical research ranging from industry and academia to authorities are keen on demonstrating better monitoring-efficiency by reducing monitoring visits, monitoring time on site, monitoring costs and so on, always arguing with the use of risk-based monitoring principles. Mostly forgotten is the fact, that the use of risk-based monitoring is only adequate if all mandatory prerequisites at site and for the monitor and the sponsor are fulfilled.Based on the relevant chapter in ICH GCP (International Conference on Harmonisation of technical requirements for registration of pharmaceuticals for human use – Good Clinical Practice this publication takes a holistic approach by identifying and describing the requirements for future monitoring and the use of risk-based monitoring. As the authors are operational managers as well as QA (Quality Assurance experts, both aspects are represented to come up with efficient and qualitative ways of future monitoring according to ICH GCP.[german] Seit einigen Jahren wird von den verschiedensten Autoren – aus den industriellen, akademischen oder behördlichen Bereichen der Klinischen Forschung – das Risiko-basierte Monitoring fast wie eine Wunderformel beschworen und bewertet. Um die damit erzielten Verbesserungsmöglichkeiten nachzuweisen, werden generelle Effizienzsteigerungen und Kosteneinsparungen bei den unterschiedlichen Monitoringaktivitäten beschrieben: weniger Monitoringbesuche am Zentrum, reduzierte Dauer der Monitoringbesuche oder mehr technisch unterstütztes Monitoring.Direkt oder indirekt enthalten die Publikationen oft auch Hinweise auf die notwendigen Voraussetzungen sowohl beim Zentrum als auch bei Monitor und Sponsor, um Risiko-basiertes Monitoring adequat einzusetzen; bei der Umsetzung werden diese Bedingungen gerne vergessen.Durch den ganzheitlichen

    Big Queues aims to give a simple and elegant account of how large deviations theory can be applied to queueing problems. Large deviations theory is a collection of powerful results and general techniques for studying rare events, and has been applied to queueing problems in a variety of ways. The strengths of large deviations theory are these: it is powerful enough that one can answer many questions which are hard to answer otherwise, and it is general enough that one can draw broad conclusions without relying on special case calculations.

    Our knowledge about the elementary particles stands before a revolution: With the biggest machine of mankind the legendary Higgs boson was discovered - and for its prediction the Nobel prize awarded. Other researchers search for antiparticles from the universe and the shadow regime of the dark matter. What has be happened after the big bang? How the components of the universe have been arised? Of which consists the world - and why it exists at all? Science reporter and cosmology specialist Ruediger Vaas bends the bow from the smallest of all to the largest of all. He analyzes the actual state of knowledge and reports about the search for a ''world formula'', which explains, what holds the universe together in the innermost. A unique excursion to the fronts of research.

    New engines for civilian aviation are to emit substantially fewer pollutants in the future. Engineers want to ensure this with so-called lean combustion chambers in jet engines. These chambers combust the air-kerosene-mixture at low temperatures and thus reduce the emissions of nitrogen oxides. At the high pressure combustion chamber test stand 1 of the institute for propulsion technology scientists of the German Aerospace Centre (DLR, Cologne, Federal Republic of Germany) together with Rolls-Royce have built a combustion chamber test section. Using cameras and laser technology they observe and analyse the lean combustion exactly.

    The delivery of psychiatric care is changing with a new emphasis on integrated care, preventative measures, population health, and the biological basis of disease. Fundamental to this transformation are big data and advances in the ability to analyze these data. The impact of big data on the routine treatment of bipolar disorder today and in the near future is discussed, with examples that relate to health policy, the discovery of new associations, and the study of rare events. The primary sources of big data today are electronic medical records (EMR), claims, and registry data from providers and payers. In the near future, data created by patients from active monitoring, passive monitoring of Internet and smartphone activities, and from sensors may be integrated with the EMR. Diverse data sources from outside of medicine, such as government financial data, will be linked for research. Over the long term, genetic and imaging data will be integrated with the EMR, and there will be more emphasis on predictive models. Many technical challenges remain when analyzing big data that relates to size, heterogeneity, complexity, and unstructured text data in the EMR. Human judgement and subject matter expertise are critical parts of big data analysis, and the active participation of psychiatrists is needed throughout the analytical process. PMID:27068058

    2015-08-01

    The concept of "big data" stands to change the face of official statistics over the coming years, having an impact on almost all aspects of data production. The tasks of future statisticians will not necessarily be to produce new data, but rather to identify and make use of existing data to adequately describe social and economic phenomena. Until big data can be used correctly in official statistics, a lot of questions need to be answered and problems solved: the quality of data, data protection, privacy, and the sustainable availability are some of the more pressing issues to be addressed. The essential skills of official statisticians will undoubtedly change, and this implies a number of challenges to be faced by statistical education systems, in universities, and inside the statistical offices. The national statistical offices of the European Union have concluded a concrete strategy for exploring the possibilities of big data for official statistics, by means of the Big Data Roadmap and Action Plan 1.0. This is an important first step and will have a significant influence on implementing the concept of big data inside the statistical offices of Germany. PMID:26077871

    The information and communication technology (ICT) is a key enabling technology for Smart Grids. With respect to very short innovation cycles for ICT compared to longer innovation cycles for the transition of the energy system there is a huge challenge to develop and exploit the potential of future ICT and their application in a future intelligent energy system. Different ICT technologies, such as Internet of Things or Cloud Computing are intensively being discussed. They can be summarized under the term ''Future Internet''. The EU project FINSENY is investigating the potential of Future Internet concepts and technologies in particular for Smart Energy systems. A series of design principles and the necessary ICT are developed, which are described in this paper. These design principles such as open interfaces, security-by-design, simplicity, maintenance, auto-configuration and modularity are of general nature. They will remain despite technology developments. Furthermore, several design principles are not only applicable to ICT but they are also related to design principles of intelligent energy systems like decentralized energy generation systems.

    Full Text Available The assessment centre: a brief review of predictive value. Factors such as the rise of the professional manager, industrialization and worker expectations have, over the last few decades, increasingly placed managers in the limelight as a key occupational group. In this regard the assessment centre has become prominent as a method for the identification of managerial potential. However, a brief review of the relevant research literature indicates low predictive variances for the managerial assessment centre. This fact, together with the limited scope of the assessment centre, therefore necessitates, amongst other things, a wider research perspective which will include other work and non-work related factors as well. Opsomming Verskynsels soos die opkoms van die professionele bestuurder, industrialisering en stygende werkerverwagtinge het meegebring dat die kollig die afgelope paar dekades al hoe meer op bestuurders as sleutelberoepskategone geplaas is.

  10. Big nuclear accidents

    International Nuclear Information System (INIS)

    Much of the debate on the safety of nuclear power focuses on the large number of fatalities that could, in theory, be caused by extremely unlikely but imaginable reactor accidents. This, along with the nuclear industry's inappropriate use of vocabulary during public debate, has given the general public a distorted impression of the safety of nuclear power. The way in which the probability and consequences of big nuclear accidents have been presented in the past is reviewed and recommendations for the future are made including the presentation of the long-term consequences of such accidents in terms of 'reduction in life expectancy', 'increased chance of fatal cancer' and the equivalent pattern of compulsory cigarette smoking.

    Energy Technology Data Exchange (ETDEWEB)

    Flohn, H.

    1981-01-01

    Man's activity increasingly affects the evolution of climate in a foreseeable future. This began as early as with the neolithic revolution (by conversion of vegetation and soil), intensified by the industrial revolution (changing atmospheric constituents, aerosol particles) and by the exponential growth of world's population. Based on recent model calculations, the role of carbon dioxide and other trace gases and the so-called greenhouse effect of the atmosphere will be discussed, as well as possible sources of error of forecasting the future fate of CO/sub 2/. Since no sufficiently realistic interactive models of the climatic system (i.e. atmosphere, ocean, cryosphere and biosphere) will be available quite soon, analogues from the historic and geologic past are offered and critically discussed. Of peculiar interest is the Pliocene (about 3-5 million years ago), during which the Antarctic continent was highly glaciated, while the Arctic Ocean was ice-free: this asymmetry verifes a model hypothesis proposed 1962 by BUDYKO. Critical thresholds of the CO/sub 2/ content are estimated; in the latter case large-scale displacements of the earth's climatic belts have to be expected.

    The time evolution of a wormhole in a Friedmann universe approaching the Big Rip is studied. The wormhole is modeled by a thin spherical shell accreting the superquintessence fluid - two different models are presented. Contrary to recent claims that the wormhole overtakes the expansion of the universe and engulfs it before the Big Rip is reached, it is found that the wormhole becomes asymptotically comoving with the cosmic fluid and the future evolution of the universe is fully causal.

    Full Text Available Mit dem Auftauchen von Discovery Systemen entstand die Hoffnung, dass der Schulungsbedarf und damit der Aufwand für die Vermittlung von Informationskompetenz verringert und durch die Systeme selbst die Informationskompetenz verbessert werden kann. Dieser Beitrag beleuchtet kritisch das Zusam­menspiel von Discovery Systemen und Informationskompetenz anhand von Recherchegewohnheiten eher untrainierter Studierender. Anhand einer kurzen Gegenüberstellung der unterschiedlichen Recherche­konzepte von Suchmaschinen und bibliothekarischen Rechercheangeboten werden Rückschlüsse auf die zu fördernden Schwerpunkte bei der Informationskompetenz gezogen und untersucht, welche Schlüsselrolle Discovery Systeme dabei spielen.The dissemination of discovery systems has raised hopes that the need for extensive teaching of information literacy might be reduced in the future. Also, their intuitive approach has been hopefully seen to enable the development of a better information literacy. This article critically focusses on the interaction of discovery systems and information literacy by analysing research behaviours of comparatively untrained students. In order to define which specific themes should be promoted by information literacy education, the author examines various research concepts of search engines as well as research offers of libraries. On this basis the key role of discovery systems will be explored.

    In the Federal Republic of Germany, the legislator introduced a fixed price system for the attainment of the goals of the renewable energy law. It is questionable whether the German fixed price model in a liberalized energy market can continue legally. The renewable energy law also is disputed constitutionally. Under this aspect, the author of the contribution under consideration reports on the future compatibility of the renewable energy law with the constitutional law and European law. First of all, the actual development of the feed-in law in the German electricity market is described. Subsequently, the development from the current feed-in law to the renewable energy law in the Federal Republic of Germany is presented. It is examined whether the renewable energy law offends against the financial constitutional law. The central point of the question is whether the addressees of the law are illegally injured in its fundamental rights from Sect. 12 GG and Sect. 14 GG. In the background the community-legal basic conditions, the compatibility of the renewable energy law with Community law recently is to be examined.

    part of the debate. Also in dispute, was the location of the Academy at Saldanha, rather than in the military heart-land in Pretoria. By interpreting the academic training needs of the Defence Force correctly and positioning itself accordingly, the Academy survived that crisis. Thereafter, the Academy time and again adapted to the changing military and socio-political environment and strove towards ever increasing relevance to the Defence Force. In this way female and non-European students were admitted to the Military Academy, whilst the way was also paved for the admittance of students from other African states. In anticipation of the new political dispensation in South Africa, a concerted effort was launched in 1990 to make the student body more representative of the South Africa population in terms of race and sex. The Military Academy has through the years established itself as a credible military academic institution and has made a significant contribution towards military professionalism in South Africa. By 1990 it favourably positioned itself to continue that role in future. Though forming only a small percentage of the total officer corps, the Academy graduates have gradually been distributed at all levels of the' officer corps and have dominated the top posts in the SA Defence Force since the early 1970's. They were consequently well placed in 1990 to play a significant role in preparing the Defence Force for the so-called "New South Africa". ****** AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse Militêre Akademie is op 1 April 1950 gestig met die doel om die militêrakademiese opleiding van kandidaatoffisiere hier te lande op dieselfde peil as in die buiteland te bring en dit terselfdertyd tot universiteitsvlak te verhef.

    We consider conditions under which a universe contracting towards a big crunch can make a transition to an expanding big bang universe. A promising example is 11-dimensional M-theory in which the eleventh dimension collapses, bounces, and re-expands. At the bounce, the model can reduce to a weakly coupled heterotic string theory and, we conjecture, it may be possible to follow the transition from contraction to expansion. The possibility opens the door to new classes of cosmological models. F...

    Large population-based health administrative databases, clinical registries, and data linkage systems are a rapidly expanding resource for health research. Ophthalmic research has benefited from the use of these databases in expanding the breadth of knowledge in areas such as disease surveillance, disease etiology, health services utilization, and health outcomes. Furthermore, the quantity of data available for research has increased exponentially in recent times, particularly as e-health initiatives come online in health systems across the globe. We review some big data concepts, the databases and data linkage systems used in eye research-including their advantages and limitations, the types of studies previously undertaken, and the future direction for big data in eye research.

Die begrip wil eintlik die ewolusionêre gang beklemtoon, want dit is dan eintlik net die ou norme wat effens anders bekyk word of nie meer so nou geneem of dik onderstreep word nie. Die verskuiwing beteken dan dat alles nog dieselfde bly, net die posisie of plek het verander. Verskuiwing beteken tog plekverandering of plekwisseling en dan sekerlik nie in die sin dat die plekke ver uitmekaar lê nie. Verskuiwing beteken net maar vlak langs die vorige te staan kom.

The big data range from data mining, data analysis and decision making, by drawing statistical rules and mathematical patterns through systematical or automatically reasoning. The big data helps serve our life better, clarify our future and deliver greater value. We can discover how to capture and analyze data. Readers will be guided to processing system integrity and implementing intelligent systems. With intelligent systems, we deal with the fundamental data management and visualization challenges in effective management of dynamic and large-scale data, and efficient processing of real-time and spatio-temporal data. Advanced intelligent systems have led to managing the data monitoring, data processing and decision-making in realistic and effective way.

    Full Text Available Die opvatting van die suiwere regstaat bring sy vraagstukke mee wanneer dit in verband gebring word met die leer van die soewereiniteit in eie kring. Laasgenoemde leer wortel in die geloof dat God die mens roep tot diens aan Hom, en dat die mens vry moet wees om ten opsigte van alle lewensaspekte God na die hoogste mate te kan dien. Hierdie verskeidenheid van aspekte is deur dr. A. Kuyper en sy volgelinge gesistemati- seer tot menslike verbande en lewenskringe, elk met ’n be- paalde sfeer waarin ander kringe nie mag inmeng nie. Elkeen is dan soewerein binne sy eie kring. Met verwysing na die staat is dan gespreek van die staatstaak as synde die hand- hawing van die reg, en omdat die staat in toenemende mate hom veral in die latere tyd ook besig gehou het met bedrywig- hede wat nouliks as van juridiese aard beskou kan word, is daar die onderskeid gemaak tussen die primêre en sekundêre taak van die staat. Die sistematiek van die wetsidee, deur prof. Dooyeweerd ontwikkel, waar die staat sy bestemmingsfunksie in die regsaspek vind, het vanselfsprekend geen plek vir so 'n dualistiese staatstaak nie, en die oplossing is deur sommige daarin gesoek om sulke staatsoptrede te vertolk as hebbende wel betrekking op die regsgemeenskap of die regsverkeer. Staatsondernemings soos paaie, spoorweë, spellingreëling, ens. word dan beskou as noodsaaklik vir die instandhouding van die regsgemeenskap en regsverkeer. Tereg wys A. M. Donner1 daarop dat so ’n vertolking eintlik neerkom op ’n oorspanning van die regsbegrip.

  11. Dual of big bang and big crunch

    International Nuclear Information System (INIS)

    Starting from the Janus solution and its gauge theory dual, we obtain the dual gauge theory description of the cosmological solution by the procedure of double analytic continuation. The coupling is driven either to zero or to infinity at the big-bang and big-crunch singularities, which are shown to be related by the S-duality symmetry.

    Full Text Available In Ou Egipte is mummifikasie met uitgebreide reseksie of uitsnyding van organe geassosieer, maar geen kennis is geneem van die morfologie van die brein nie. Griekse skrywers van die sesde en vyfde eeue v.C. het die brein aanvanklik gesien as die setel van intelligensie, die orgaan van sensoriese waarneming en gedeeltelik die oorsprong van sperma. Pneuma het ’n belangrike rol in breinfunksie gespeel. Hippokrates was die eerste om die brein te beskryf as ’n dubbele orgaan, wat met harsingvlies (meninges bedek, funksioneel van pneuma afhanklik en vertolker van begrip is. Tydgenote soos Plato, Aristoteles en Diokles het tot die beskrywing bygedra, maar laasgenoemde twee het beweer dat die hart die middelpunt van intelligensie is en nie die brein nie. Gedurende die laaste helfte van die vierde eeu v.C. is disseksie van die menslike liggaam tydelik aan die mediese skool van Alexandrië toegelaat en het dit tot merkwaardige vooruitgang in die begrip van die menslike anatomie en fisiologie gelei. Herofilus en Erasistratus het uitstekende beskrywings van die struktuur en funksie van die brein gegee wat eers in die tweede eeu n.C. deur Galenus geëwenaar is.

    International Nuclear Information System (INIS)

    Business to business electronic commerce is looming large in the future of the oil industry. It is estimated that by adopting e-commerce the industry could achieve bottom line savings of between $1.8 to $ 3.4 billion a year on annual gross revenues in excess of $ 30 billion. At present there are several teething problems to overcome such as inter-operability standards, which are at least two or three years away. Tying in electronically with specific suppliers is also an expensive proposition, although the big benefits are in fact in doing business with the same suppliers on a continuing basis. Despite these problems, 14 of the world's largest energy and petrochemical companies joined forces in mid-April to create a single Internet procurement marketplace for the industry's complex supply chain. The exchange was designed by B2B (business-to-business) software provider, Commerce One Inc., ; it will leverage the buying clout of these industry giants (BP Amoco, Royal Dutch Shell Group, Conoco, Occidental Petroleum, Phillips Petroleum, Unocal Corporation and Statoil among them), currently about $ 125 billion on procurement per year; they hope to save between 5 to 30 per cent depending on the product and the region involved. Other similar schemes such as Chevron and partners' Petrocosm Marketplace, Network Oil, a Houston-based Internet portal aimed at smaller petroleum companies, are also doing business in the $ 10 billion per annum range. e-Energy, a cooperative project between IBM Ericson and Telus Advertising is another neutral, virtual marketplace targeted at the oil and gas sector. PetroTRAX, a Calgary-based website plans to take online procurement and auction sales a big step forward by establishing a portal to handle any oil company's asset management needs. There are also a number of websites targeting specific needs: IndigoPool.com (acquisitions and divestitures) and WellBid.com (products related to upstream oil and gas operators) are just two examples.

    Big Data has gained much attention from the academia and the IT industry. In the digital and computing world, information is generated and collected at a rate that rapidly exceeds the boundary range. Currently, over 2 billion people worldwide are connected to the Internet, and over 5 billion individuals own mobile phones. By 2020, 50 billion devices are expected to be connected to the Internet. At this point, predicted data production will be 44 times greater than that in 2009. As information is transferred and shared at light speed on optic fiber and wireless networks, the volume of data and the speed of market growth increase. However, the fast growth rate of such large data generates numerous challenges, such as the rapid growth of data, transfer speed, diverse data, and security. Nonetheless, Big Data is still in its infancy stage, and the domain has not been reviewed in general. Hence, this study comprehensively surveys and classifies the various attributes of Big Data, including its nature, definitions, rapid growth rate, volume, management, analysis, and security. This study also proposes a data life cycle that uses the technologies and terminologies of Big Data. Future research directions in this field are determined based on opportunities and several open issues in Big Data domination. These research directions facilitate the exploration of the domain and the development of optimal techniques to address Big Data. PMID:25136682

    The idea that the purely phenomenological knowledge that we can extract by analyzing large amounts of data can be useful in healthcare seems to contradict the desire of VPH researchers to build detailed mechanistic models for individual patients. But in practice no model is ever entirely phenomenological or entirely mechanistic. We propose in this position paper that big data analytics can be successfully combined with VPH technologies to produce robust and effective in silico medicine solutions. In order to do this, big data technologies must be further developed to cope with some specific requirements that emerge from this application. Such requirements are: working with sensitive data; analytics of complex and heterogeneous data spaces, including nontextual information; distributed data management under security and performance constraints; specialized analytics to integrate bioinformatics and systems biology information with clinical observations at tissue, organ and organisms scales; and specialized analytics to define the "physiological envelope" during the daily life of each patient. These domain-specific requirements suggest a need for targeted funding, in which big data technologies for in silico medicine becomes the research priority. PMID:26218867

BigDog is aimed at the mission of a mechanical mule - a category with few competitors to date: power autonomous quadrupeds capable of carrying significant payloads, operating outdoors, with static and dynamic mobility, and fully integrated sensing. BigDog is about 1 m tall, 1 m long and 0.3 m wide, and weighs about 90 kg. BigDog has demonstrated walking and trotting gaits, as well as standing up and sitting down. Since its creation in the fall of 2004, BigDog has logged tens of hours of walking, climbing and running time. It has walked up and down 25 & 35 degree inclines and trotted at speeds up to 1.8 m/s. BigDog has walked at 0.7 m/s over loose rock beds and carried over 50 kg of payload. We are currently working to expand BigDog's rough terrain mobility through the creation of robust locomotion strategies and terrain sensing capabilities.

    The amount of data at the global level has grown exponentially. Along with this phenomena, we have a need for a new unit of measure like exabyte, zettabyte, and yottabyte as the last unit measures the amount of data. The growth of data gives a situation where the classic systems for the collection, storage, processing, and visualization of data losing the battle with a large amount, speed, and variety of data that is generated continuously. Many of data that is created by the Internet of Things, IoT (cameras, satellites, cars, GPS navigation, etc.). It is our challenge to come up with new technologies and tools for the management and exploitation of these large amounts of data. Big Data is a hot topic in recent years in IT circles. However, Big Data is recognized in the business world, and increasingly in the public administration. This paper proposes an ontology of big data analytics and examines how to enhance business intelligence through big data analytics as a service by presenting a big data analytics services-oriented architecture. This paper also discusses the interrelationship between business intelligence and big data analytics. The proposed approach in this paper might facilitate the research and development of business analytics, big data analytics, and business intelligence as well as intelligent agents.

    This book is a collection of chapters written by experts on various aspects of big data. The book aims to explain what big data is and how it is stored and used. The book starts from  the fundamentals and builds up from there. It is intended to serve as a review of the state-of-the-practice in the field of big data handling. The traditional framework of relational databases can no longer provide appropriate solutions for handling big data and making it available and useful to users scattered around the globe. The study of big data covers a wide range of issues including management of heterogeneous data, big data frameworks, change management, finding patterns in data usage and evolution, data as a service, service-generated data, service management, privacy and security. All of these aspects are touched upon in this book. It also discusses big data applications in different domains. The book will prove useful to students, researchers, and practicing database and networking engineers.

One very interesting stream of research on Big Data analyzes online networks. Many online networks are known to have some typical macro-characteristics, such as ‘small world’ properties. Much less is known about underlying micro-processes leading to these properties. The models used by Big Data researchers usually are inspired by mathematical ease of exposition. We propose to follow in addition a different strategy that leads to knowledge about micro-processes that match with actual online behavior. This knowledge can then be used for the selection of mathematically-tractable models of online network formation and evolution. Insight from social and behavioral research is needed for pursuing this strategy of knowledge generation about micro-processes. Accordingly, our proposal points to a unique role that social scientists could play in Big Data research. ...

    The big bang theory is a model of the universe which makes the striking prediction that the universe began a finite amount of time in the past at the so called "Big Bang singularity." We explore the physical and mathematical justification of this surprising result. After laying down the framework of the universe as a spacetime manifold, we combine physical observations with global symmetrical assumptions to deduce the FRW cosmological models which predict a big bang singularity. Next we prove a couple theorems due to Stephen Hawking which show that the big bang singularity exists even if one removes the global symmetrical assumptions. Lastly, we investigate the conditions one needs to impose on a spacetime if one wishes to avoid a singularity. The ideas and concepts used here to study spacetimes are similar to those used to study Riemannian manifolds, therefore we compare and contrast the two geometries throughout.

    Big Bang Nucleosynthesis (BBN), along with the cosmic background radiation and the Hubble expansion, is one of the pillars ofthe standard, hot, big bang cosmology since the primordial synthesis of the light nuclides (D, $^3$He, $^4$He, $^7$Li) must have occurred during the early evolution of a universe described by this model. The overall consistency between the predicted and observed abundances of the light nuclides, each of which spans a range of some nine orders of magnitude, provides impr...

    Oft werden zwei mögliche Entwicklungen des Webs diskutiert - das Web 2.0 und das Semantic Web. Wenn wir diese zwei Visionen für das zukünftige Web unter die Lupe nehmen, dann lässt sich feststellen, dass sich die Ideen in ihrem Kern und ihren Technologien gegenseitig ergänzen. Dementsprechend können und sollen beide Visionen von den Erfahrungen und Stärken der anderen profitieren. Wir glauben daran, dass zukünftige Webanwendungen den Web 2.0-Fokus auf Community und Benutzerfreundlichkeit beibehalten und, darüber hinaus, auch von Technologien des Semantic Web zur Vereinfachung der mashupähnlichen Datenintegration profitieren werden. Auf Basis eines Semantic Blog-Szenarios werden wir hier die Vorteile einer möglichen Kombination von Semantic Web und Web 2.0 illustrieren, die zeitnah realisiert werden kann. Wir werden auch auf technische Probleme eingehen, die bei der Erweiterung dieses Szenarios entstehen. Wir stellen dar, wie aktuelle Entwicklungen in der Semantic Web Forschung diese Probleme angehen können, und setzen zugleich auch Schwerpunkte für die zukünftige Forschung, die in diesem Zusammenhang relevant sind.

The aim of this study is to design a measuring instrument with acceptable metric characteristics for the strength of the psychological contract within the South African context, and to determine empirically the relation between the strength of the psychological contract and organisational commitment. The Dhammanungune Model served as foundation for the design of the Strength of the Psychological Contract Questionnaire which consists of two scales namely, a needs expectation scale and a needs fulfilment expectation scale. The items of each scale have been formulated in the manner that ensures that the respondent reacts consecutively to two instructions namely, (a the level of the expectation and (b the importance of the expectation. This questionnaire was administered together with the Organisational Commitment Questionnaire to two population groups within the military environment. The Pearson Product Moment Correlation was calculated between the strength of the psychological contract and organisational commitment and the significance of the correlations was evaluated. Opsomming Die doel van die studie is om 'n meetinstrument met aanvaarbare metriese eienskappe vir die sterkte van die sielkundige kontrak vir Suid-Afrikaanse omstandighede te ontwerp en om empirics die verband tussen die sterkte van die sielkundige kontrak en organisasieverbondenheid te bepaal.

    Pinto-Neto, Nelson; 10.1103/PhysRevD.80.083509

    2009-01-01

    It is shown in this paper that minisuperspace quantization of homogeneous and isotropic geometries with phantom scalar fields, when examined in the light of the Bohm-de Broglie interpretation of quantum mechanics, does not eliminate, in general, the classical big rip singularity present in the classical model. For some values of the Hamilton-Jacobi separation constant present in a class of quantum state solutions of the Wheeler-DeWitt equation, the big rip can be either completely eliminated or may still constitute a future attractor for all expanding solutions. This is contrary to the conclusion presented in Ref.[1], using a different interpretation of the wave function, where the big rip singularity is completely eliminated ("smoothed out") through quantization, independently of such separation constant and for all members of the above mentioned class of solutions. This is an example of the very peculiar situation where different interpretations of the same quantum state of a system are predicting different...

Hulle wil net een vaderland ken, en dit is Suid-Afrika. Die daadwerklike uitvloeisel van hierdie begeerte word ook in hulle taalgebruik weerspieël.

    1976-11-01

    Full Text Available Ergonomics (a synonym for human factors engineering has contributed significantly to fundamental effectiveness of people, but needs a new emphasis and wider applications in future. A basic distinction is drawn between the areas of application and the focus of ergonomists. Although applications have been relatively successful in the military and industrial fields, ergonomics should also be applied to consumer products, architecture, transportation and recreation. In future, the primary challenge will be to improve the "quality of life" by enhancing human satisfaction and allowing people to function at higher value levels. In work activities the basic task of ergonomics has been to simplify and standardise jobs, but future focus should be on enlargement and enrichment of jobs. Because of individual differences probably not all jobs could be made completely satisfactory to all workers. However, significant contributions could be made through continued efforts to “humanise” work activities.Opsomming Ergonomika ('n sinoniem vir "human factors engineering" het reeds heelwat bygedra tot die doeltreffende funksionering van die mens, maar nuwe gesigspunte en toepassingsvelde sal in die toekoms nodig wees. 'n Fundamentele onderskeid word getref tussen die gebiede van toepassing en die fokus van beoefenaars van die ergonomika. Hoewel toepassings in die militêre en industriële sfere redelik suksesvol was, behoort ergonomiese beginsels ook op verbruikerswese, argitektuur, vervoer en ontspanning toegepas te word. Die grootste uitdaging in die toekoms sal egter wees om "lewenskwaliteit" te verbeter deur tevredenheid te verhoog en mense te help om doeltreffender te leef en in die proses hoër waardevlakke te handhaaf. In werksaktiwiteite was die hoofdoel tot dusver om werk te standaardiseer en te vereenvoudig, maar dit word al hoe noodsaakliker dat poste verruim en verryk moet word.

Marcant and sometimes little known examples show the different functions of intabulations: repertoire for the organists (liturgical function, music of delight and pedagogical functions. As a part of Ars Organistum intabulations were the basis of professional musical studies, learning to improvise organ music and to compose music. Masters like H. Scheidemann, the both Gabrielis, J. de Lublin, P. Philips, the both Cabezóns, some English and French anonym composers demonstrate that intabulations are much more than keyboard reductions - artful arrangements with their own life and character on the way to artful paraphrases.

    Nowadays strategies of prevention and sustainability are frequently discussed. However, the increasing number of studies and programs has hardly contributed to reducing the obvious contradiction between the aim of sustainability and reality as well as to the predominat economic policy. One reason for that is that strategies of prevention, which are defined for the use of materials and energy services, are not sufficiently linked to economic instruments which put the ideas into practice. This article starts from the assumption that both the way of producing and life-styles for saving resources and energy and `the ecologization` of products and markets, will lead to a regional and national strengthening of the `cycle economy` in material as well as in economic respects. For an `economy of prevention` it is necessary to apply a set mix of strategies and instruments (for example `Least-Cost Planning) which work at different levels of action and which have to be different as far as the intensity of intervention is concerned. On the other hand it is important to create self-regulating arrangements which offer economic incentives. `Least-Cost Planning` in electric power economy has been proved to be successful up to now. But this core instrument of an `economy of prevention` must be adopted to other sectors and must be embedded in a sector- and target-groups specific bundle of instruments. In this context `economy of prevention` means looking for these sets of instruments specific to the relevant fields and target groups which could act as an incentive in the key fields of energy, transport, water and waste to avoid wasting resources and the environment. This article shows selected examples of the application of `the economy of prevention`. (orig.) [Deutsch] Vermeidungs- und Nachhaltigkeitskonzepte haben derzeit Konjunktur.

    Full Text Available Any peace process is an exercise in the negotiation of big data. From centuries old communal hagiography to the reams of official texts, media coverage and social media updates, peace negotiations generate data. Peacebuilding and peacekeeping today are informed by, often respond and contribute to big data. This is no easy task. As recently as a few years ago, before the term big data embraced the virtual on the web, what informed peace process design and implementation was in the physical domain – from contested borders and resources to background information in the form of text. The move from analogue, face-to-face negotiations to online, asynchronous, web-mediated negotiations – which can still include real world meetings – has profound implications for how peace is strengthened in fragile democracies.

    2014-01-01

    Big data introduces challenges to query answering, from theory to practice. A number of questions arise. What queries are “tractable” on big data? How can we make big data “small” so that it is feasible to find exact query answers? When exact answers are beyond reach in practice, what approximation theory can help us strike a balance between the quality of approximate query answers and the costs of computing such answers? To get sensible query answers in big data, what else do we necessarily do in addition to coping with the size of the data? This position paper aims to provide an overview of recent advances in the study of querying big data. We propose approaches to tackling these challenging issues, and identify open problems for future research.

    Full Text Available Nooit sou die Franse jeug — en die van Europa en verder — in dié mate deur die eksistensialisme be'invloed gewees het nie, indien hierdie filosofie in wysgerige traktate sou begrawe gelê het. Die eksistensialiste het die koning van die filosofiese verhaal, Voltaire, met sukses op sy Candide- en Zadig-pad gevolg en hulle teorieë in letterkundige werke, ver- hale, romans en ook toneelstukke kwytgeraak, wat baie gelees is en waaruit ook ander literatore kragte en inspirasie geput het. Omrede daarvan is daar inderdaad baie eksistensialisme in die Franse letterkunde, maar ’n eintlike eksistensialistiese letterkunde was daar nie, en ’n Eksistensialistiese Letterkun­ dige skool het nooit bestaan nie. Ook sit hierdie eksistensialiste nie langs dieselfde vuur nie. Die Christelike eksistensialis Gabriel Marcel het op 21 April van hierdie jaar uitgevaar teen die „Sartriane” na aanleiding van die opvoering van Les Paravents, Die W indskerms van Jean Genêt in ’n Paryse staatsondersteunde teater. „Mens mag seker wees”, skryf Marcel in Les Nouvelles Littéraires, „dat die hele sartriaanse parogie sal skreeu: groot meesterwerk”. Voortgaande op sy distansiëring kan die literêre eksistensialiste in drie groepe ingedeel word: 1. Die Sartriane; 2. Die Christelike Eksistensialiste; 3. Die Onafhanklikes.

    Energy consumption has decreased by 4.7 percent compared to the year 2013 in the year, 2014. The relatively mild weather of 2014 was significant responsible. The energy consumption reached 13,132 petajoules the lowest level since 1990. The renewable energies are Germany's most important power source. The share of renewable energy in electricity consumption in the first half 2015 was for the first time more than 30 percent. In the expansion of renewable energies in the electricity sector, Germany is on target. The amount of the EEG surcharge has stabilized. The average increase of the energy efficiency 2008-2014 was 1.6 percent lower than envisaged in the energy concept of the federal government of 2.1 percent. Here additional action is needed. The Federal Government has therefore bundled and enforced with the National Energy Efficiency Action Plan decided on December 3, 2014 to increase and to sthrengthend efficiency. Final energy consumption in transport was in 2014 approximately 1.7 percent higher than in 2005. In order to achieve the objective of reducing the final energy consumption by 10 percent compared to 2005, further efforts are needed. For the first time for over ten years electricity prices decreased at the beginning of 2015, for household customers. For industrial and commercial customers, which are not covered by an asset relief scheme, electricity prices in 2014 remained almost unchanged. The spot price of electricity is 2014 declined by 10 per cent and continued to decline in 2015. In 2014, Germany imported fossil fuels worth around 81 billion euros. In 2013 there were still 95 billion euros. The decline in import expenditure mainly due to lower raw material prices, but lower import volumes have also contributed.

  7. Big Bear Exploration Ltd. 1998 annual report

    International Nuclear Information System (INIS)

    During the first quarter of 1998 Big Bear completed a purchase of additional assets in the Rainbow Lake area of Alberta in which light oil purchase was financed with new equity and bank debt. The business plan was to immediately exploit these light oil assets, the result of which would be increased reserves, production and cash flow. Although drilling results in the first quarter on the Rainbow Lake properties was mixed, oil prices started to free fall and drilling costs were much higher than expected. As a result, the company completed a reduced program which resulted in less incremental loss and cash flow than it budgeted for. On April 29, 1998, Big Bear entered into agreement with Belco Oil and Gas Corp. and Moan Investments Ltd. for the issuance of convertible preferred shares at a gross value of $15,750,000, which shares were eventually converted at 70 cents per share to common equity. As a result of the continued plunge in oil prices, the lending value of the company's assets continued to fall, requiring it to take action in order to meet its financial commitments. Late in the third quarter Big Bear issued equity for proceeds of $11,032,000 which further reduced the company's debt. Although the company has been extremely active in identifying and pursuing acquisition opportunities, it became evident that Belco Oil and Gas Corp. and Big Bear did nor share common criteria for acquisitions, which resulted in the restructuring of their relationship in the fourth quarter. With the future of oil prices in question, Big Bear decided that it would change its focus to that of natural gas and would refocus ts efforts to acquire natural gas assets to fuel its growth. The purchase of Blue Range put Big Bear in a difficult position in terms of the latter's growth. In summary, what started as a difficult year ended in disappointment

The results of this research support the prediction that situational variables such as time-span of discretion tend to moderate the relationship between Leadership style and group performance. Implications for future theory development, research and applications are discussed. Opsomming In 'n gekontroleerde laboratorium- en kontrolestudie is die verband tussen leierskapstyl en bestuursdoeltreffendheid onder verskillende tydspantoestande bepaal. Resultate toon aan dat beide leierskapstyl en tydspan 'n invloed uitoefen op bestuursdoeltreffendheid. Doeltreffendheid kan beskou word as 'n funksie van die aanpassing van basiese leierskapstyl by die betrokke situasie.

    Full Text Available Während der systolische Blutdruck in der Bevölkerung mit zunehmendem Lebensalter in jedem Dezennium weiter ansteigt, beginnt der diastolische Blutdruck ab dem 50. Lebensjahr für jede systolische Blutdruckstratifizierung als Ausdruck einer zunehmenden Gefäßschädigung wieder zu sinken. Deswegen muß der Blutdruck ausschließlich nach dem systolischen Blutdruck klassifiziert werden. Die Häufigkeitsverteilung des systolischen und diastolischen Blutdrucks innerhalb der Bevölkerung entspricht einer Gauss'schen Glockenkurve. Jede Unterteilung in normotensiv und hypertensiv entspricht deshalb einer völlig willkürlichen Dichotomisierung. Je niedriger der Blutdruck, desto geringer die mechanische Belastung der Blutgefäße und desto geringer auch die mechanisch induzierten Gefäßschäden. Das war der Grund für die zuletzt vom "7th JNC on Prevention, Detection and Treatment of Hypertension" des NIH, USA, vorgenommene Klassifizierung des Blutdrucks in normal (kleiner als 120 mmHg systolisch, prähypertensiv (120-140 mmHg und Hypertonie-Stadium I (140-160 mmHg systolisch und Hypertonie-Stadium II ( 160 mmHg systolisch. Damit muß leider die nahezu gesamte gesunde österreichische Bevölkerung, die nach bisheriger Klassifikation noch keinen Hochdruck aufweist, als prähypertensiv klassifiziert werden. Ein wirklicher Informationsgewinn (der ja mit der Klassifikation bezweckt wird ist meiner Meinung nach damit nicht mehr gegeben. Die Österreichische Hochdruckliga schlägt eine zusätzliche Klassifikation des Blutdrucks nach dem „Pressure Load“ vor, welches aus einer statistisch aussagekräftigen Zahl von Selbstmessungen leicht zu errechnen ist. Jedes Pressure Load von mehr als 20 % (mehr als 20 % der selbst gemessenen Blutdruckwerte 135/85 mmHg entspricht einer Hypertonie, die je nach Höhe der Blutdruckwerte entweder mit Änderungen des Lebensstils oder mit antihypertensiver Medikation zu bekämpfen ist.

  1. Business and Science - Big Data, Big Picture

    Science.gov (United States)

    Rosati, A.

    2013-12-01

    Data Science is more than the creation, manipulation, and transformation of data. It is more than Big Data. The business world seems to have a hold on the term 'data science' and, for now, they define what it means. But business is very different than science. In this talk, I address how large datasets, Big Data, and data science are conceptually different in business and science worlds. I focus on the types of questions each realm asks, the data needed, and the consequences of findings. Gone are the days of datasets being created or collected to serve only one purpose or project. The trick with data reuse is to become familiar enough with a dataset to be able to combine it with other data and extract accurate results. As a Data Curator for the Advanced Cooperative Arctic Data and Information Service (ACADIS), my specialty is communication. Our team enables Arctic sciences by ensuring datasets are well documented and can be understood by reusers. Previously, I served as a data community liaison for the North American Regional Climate Change Assessment Program (NARCCAP). Again, my specialty was communicating complex instructions and ideas to a broad audience of data users. Before entering the science world, I was an entrepreneur. I have a bachelor's degree in economics and a master's degree in environmental social science. I am currently pursuing a Ph.D. in Geography. Because my background has embraced both the business and science worlds, I would like to share my perspectives on data, data reuse, data documentation, and the presentation or communication of findings. My experiences show that each can inform and support the other.

  10. Navigating "Assisted Dying".

    Science.gov (United States)

    Schipper, Harvey

    2016-02-01

    Carter is a bellwether decision, an adjudication on a narrow point of law whose implications are vast across society, and whose impact may not be realized for years. Coupled with Quebec's Act Respecting End-of-life Care it has sharply changed the legal landscape with respect to actively ending a person's life. "Medically assisted dying" will be permitted under circumstances, and through processes, which have yet to be operationally defined. This decision carries with it moral assumptions, which mean that it will be difficult to reach a unifying consensus. For some, the decision and Act reflect a modern acknowledgement of individual autonomy. For others, allowing such acts is morally unspeakable. Having opened the Pandora's Box, the question becomes one of navigating a tolerable societal path. I believe it is possible to achieve a workable solution based on the core principle that "medically assisted dying" should be a very rarely employed last option, subject to transparent ongoing review, specifically as to why it was deemed necessary. My analysis is based on 1. The societal conditions in which have fostered demand for "assisted dying", 2. Actions in other jurisdictions, 3. Carter and Quebec Bill 52, 4. Political considerations, 5. Current medical practice. Leading to a series of recommendations regarding. 1. Legislation and regulation, 2. The role of professional regulatory agencies, 3. Medical professions education and practice, 4. Public education, 5. Health care delivery and palliative care. Given the burden of public opinion, and the legal steps already taken, a process for assisted-dying is required. However, those legal and regulatory steps should only be considered a necessary and defensive first step in a two stage process. The larger goal, the second step, is to drive the improvement of care, and thus minimize assisted-dying. PMID:27169205

Aandag word gegee aan die ligging en uitleg van die brandproefherhalings in die struikmopanieveld. Die metode van opname van die houtagtige komponente en die veldlaag word bespreek, sowel as die kriteria wat gebruik is in die vergelyking tussen brandbehandelings. 'n Fitososiologiese tabel van die verskillende persele is opgestel met spesifieke verwysing na die verskille in grondsoorte en hoe dit die floristiese samestelling bei'nvloed. Uit die resultate wat verkry is, is dit duidelik dat meer frekwente brande 'n nadelige invloed op die veldlaag het. Dit hang egter grootliks at van die seisoen van diejaar waarin gebrand word, sowel as die reenval en gepaardgaande opbou van brandbare materiaal. Brande in Augustus, Oktober en Desember is strawwer en rig meer skade in die veldlaag aan. In 'n nat siklus word die houtagtige komponent beter beheer deur 'n meer frekwente brand, maar as dit in 'n droe siklus toegepas word, kan dit lei tot bosindringing. 'n Oorwegende gevolgtrekking van hierdie studie is dat 'n brand* beleid wat nie daarop ingestel is om die natuurlike regime sover moontlik te simuleer nie, tot veldagteruitgang kan lei.

    Full Text Available Big Data analytics has started to impact all types of organizations, as it carries the potential power to extract embedded knowledge from big amounts of data and react according to it in real time. The current technology enables us to efficiently store and query large datasets, the focus is now on techniques that make use of the complete data set, instead of sampling. This has tremendous implications in areas like machine learning, pattern recognition and classification, sentiment analysis, social networking analysis to name a few. Therefore, there are a number of requirements for moving beyond standard data mining technique. Purpose of this paper is to understand various techniques to analysis data.

  20. Really big numbers

    CERN Document Server

    Schwartz, Richard Evan

    2014-01-01

    In the American Mathematical Society's first-ever book for kids (and kids at heart), mathematician and author Richard Evan Schwartz leads math lovers of all ages on an innovative and strikingly illustrated journey through the infinite number system. By means of engaging, imaginative visuals and endearing narration, Schwartz manages the monumental task of presenting the complex concept of Big Numbers in fresh and relatable ways. The book begins with small, easily observable numbers before building up to truly gigantic ones, like a nonillion, a tredecillion, a googol, and even ones too huge for names! Any person, regardless of age, can benefit from reading this book. Readers will find themselves returning to its pages for a very long time, perpetually learning from and growing with the narrative as their knowledge deepens. Really Big Numbers is a wonderful enrichment for any math education program and is enthusiastically recommended to every teacher, parent and grandparent, student, child, or other individual i...

    "Big data" has become a major area of research and associated funding, as well as a focus of utopian thinking. In the still growing research community, one of the favourite optimistic analogies for data processing is that of the oil refinery, extracting the essence out of the raw data. Pessimists look for their imagery to the other end of the petrol cycle, and talk about the "data exhausts" of our society. Obviously, the refinement community knows how to do "refining".

    Reductionist science produces causal models of small fragments of complicated systems. Causal models of entire systems can be hard to construct because what is known of them is distributed across a vast amount of literature. The Big Mechanism program aims to have machines read the literature and assemble the causal fragments found in individual papers into huge causal models, automatically. The current domain of the program is cell signalling associated with Ras-driven cancers.

    Die Urknallmaschine, an Austrian film by Gerd Baldauf, narrated by Norbert Frischauf (Alpha Österreich - ORF, 2009).  In CERN’s gigantic complex particles are accelerated to almost the speed of light, brought to collision and made to divide into even smaller particles. Public opinion of CERN’s research is also divided. Sceptics fear that black holes may be created. Might the goal to study the origin of the world lead to its destruction? The Austrian researcher Norbert Frischauf worked at CERN for many years. With his guidance it is possible to explore the world’s largest research centre, get a glimpse of the fascinating work the scientists do there and take a crash course in particle physics. Die Urknallmaschine will be presented on Friday, 25 June from 13:00 to 14:00 in the Main Auditorium. Language: German

    2009-01-01

    This book presents a new method for the design of the precision dies used in cold-forging, extrusion and drawing processes. The method is based upon die expansion, and attempts to provide a clear-cut theoretical basis for the selection of critical die dimensions for this group of precision dies when the tolerance on product diameter (or thickness) is specified. It also presents a procedure for selecting the minimum-production-cost die from among a set of design alternatives. The mathematical content of the book is relatively simple and will present no difficulty to those who have taken basic c

  19. Die struktuur van die tekskode: die strukturele organisasie van 'Die jonkmanskas' van Koos Prinsloo

    Directory of Open Access Journals (Sweden)

    R. Botha

    1989-05-01

    Full Text Available A unique quality of literature is that the text system is not just an instrument for conveying a literary message; the structure of the system is in itself meaningful. This article will closely examine the structural organisation and the functional significance of Koos Prinsloo’s short story “Die Jonkmanskas” . “Die jonkmanskas” is a story with a complex structure, written in the postmodernist idiom, and originated from three distinct stories. These embedded stories simultaneously work as commentaries, parodies and corrective devices, so that the ultimate interpretation of “Die jonkmanskas” is also determined through its structural code. An important aspect of this short story, which is highlighted by the structural code, is the interaction between the author’s text, the narrator’s text and the character’s text. In this [pseudo] autobiography the distinction between the actual author, the abstract author and the narrator is gradually erased, because time and again the narrator changes his role from character to narrator to author.

Kastrering vir religieuse redes was deel van godsdiensrituele gekoppel aan verering van aardgodinne en fertiliteit. Die kultusse wat aan die godinne Kubele, Hekate, Atargatis-Dea, Astarte, Artemis en Innana-Ishtar gewy was en wat deur eunugpriesters bedien was, word beskryf. Kastrering vir niereligieuse redes, oorwegend weens sosio-ekonomiese oorwegings, het waarskynlik tydens die 2de millennium v.C. sy oorsprong in Midde-Oosterse lande gehad vanwaar dit teen ongeveer die 5de eeu v.C. na Griekeland, en twee eeue later na Rome uitgebrei het. ’n Oorsig word gelewer van die invloed en rol van die eunug ten tye van die klassieke beskawing. Die sogenaamde “kongenitale eunug” waar hipogonadisme weens ’n aangebore letsel ontstaan, ’n baie seldsame verskynsel, word nie verder bespreek nie.

    We construct phantom energy models with the equation of state parameter w which is less than -1, w<-1, but finite-time future singularity does not occur. Such models can be divided into two classes: (i) energy density increases with time ('phantom energy' without 'Big Rip' singularity) and (ii) energy density tends to constant value with time ('cosmological constant' with asymptotically de Sitter evolution). The disintegration of bound structure is confirmed in Little Rip cosmology. Surprisingly, we find that such disintegration (on example of Sun-Earth system) may occur even in asymptotically de Sitter phantom universe consistent with observational data. We also demonstrate that non-singular phantom models admit wormhole solutions as well as possibility of Big Trip via wormholes.

    Full Text Available The activity of the female communicant during worship services in the Reformed Churches in South Africa (GKSA This article is a report of research done on how a female communicant in the GKSA can be active in Christ while certain traditions tie her tongue, hands and feet. By attempting to outline the internal and external activity of female communicants during worship, this article attempts to determine empirically the extent to which current church practice is Scriptural within The Reformed tradition. Definite and specific tendencies regarding the nature of female ministerial empowerment in the churches have been noticed. Suggestions concerning expanding the involvement by women during worship services have also been indicated. A possible response to the questions raised in this regard depends on the attitude and willingness of the GKSA to correct inhibiting and unbiblical traditions and to reform according to the essence of the Bible. Real reformation is the only way to ensure that a Reformed scriptural approach towards female Christians will be practised in future – an approach that will enable female members to participate fully in worship services.

    How Big is Earth celebrates the Year of Light. Using only the sunlight striking the Earth and a wooden dowel, students meet each other and then measure the circumference of the earth. Eratosthenes did it over 2,000 years ago. In Cosmos, Carl Sagan shared the process by which Eratosthenes measured the angle of the shadow cast at local noon when sunlight strikes a stick positioned perpendicular to the ground. By comparing his measurement to another made a distance away, Eratosthenes was able to calculate the circumference of the earth. How Big is Earth provides an online learning environment where students do science the same way Eratosthenes did. A notable project in which this was done was The Eratosthenes Project, conducted in 2005 as part of the World Year of Physics; in fact, we will be drawing on the teacher's guide developed by that project.How Big Is Earth? expands on the Eratosthenes project by providing an online learning environment provided by the iCollaboratory, www.icollaboratory.org, where teachers and students from Sweden, China, Nepal, Russia, Morocco, and the United States collaborate, share data, and reflect on their learning of science and astronomy. They are sharing their information and discussing their ideas/brainstorming the solutions in a discussion forum. There is an ongoing database of student measurements and another database to collect data on both teacher and student learning from surveys, discussions, and self-reflection done online.We will share our research about the kinds of learning that takes place only in global collaborations.The entrance address for the iCollaboratory is http://www.icollaboratory.org.

Daardeur word geïmpliseer dat hierdie stelsels een transendentale, unieke vaste beginsel gebruik om ’n hele stelsel van kerkregering van buite af te bepaal. Volgens Leo Koffeman, ’n voorstander van ’n ekumeniese kerkreg, plaas hierdie stelsels hulself hiermee buite die diskoers oor kerkreg en kerkregering en die beweging van die Heilige Gees. ’n Ekumeniese kerkreg, daarenteen, is ten gunste van ’n gemeenskaplike kerkreg tussen kerke. Omdat dit verskillende tradisies bymekaar bring, is dit ’n kritiese en daarom beter benadering. Die skrywer oorweeg hierdie argumente krities in die lig van ’n gereformeerde benadering tot kerkreg.

    I review standard big bang nucleosynthesis and some versions of nonstandard BBN. The abundances of the primordial isotopes D, He-3, and Li-7 produced in standard BBN can be calculated as a function of the baryon density with an accuracy of about 10%. For He-4 the accuracy is better than 1%. The calculated abundances agree fairly well with observations, but the baryon density of the universe cannot be determined with high precision. Possibilities for nonstandard BBN include inhomogeneous and antimatter BBN and nonzero neutrino chemical potentials.

    Much of what constitutes Big Data is information about us. Through our online activities, we leave an easy-to-follow trail of digital footprints that reveal who we are, what we buy, where we go, and much more. This eye-opening book explores the raging privacy debate over the use of personal data, with one undeniable conclusion: once data's been collected, we have absolutely no control over who uses it or how it is used. Personal data is the hottest commodity on the market today-truly more valuable than gold. We are the asset that every company, industry, non-profit, and government wants. Pri

    Clozel, Harris and Taylor have recently proved a modularity lifting theorem of the following general form: if rho is an l-adic representation of the absolute Galois group of a number field for which the residual representation rho-bar comes from a modular form then so does rho. This theorem has numerous hypotheses; a crucial one is that the image of rho-bar must be "big," a technical condition on subgroups of GL(n). In this paper we investigate this condition in compatible systems. Our main r...

  19. Temperature field and failure analysis of die-casting die

    Full Text Available Purpose: Dies for aluminium alloys die-casting fail because of a great number of a different and simultaneously operating factors. Some of them may be controlled to some extent by the die-casting experts.Design/methodology/approach: In the experimental part of our work the failures on the working surface of the fixed half of the testing die for die-casting of aluminium alloys were observed with the use of non-destructive testing methods: such as thermographic analysis, penetrants, and metallographic examination of polymeric replicas.Findings: In the process of the die-casting the primary source of loading is cyclic variation of the temperature; the influence of other loads is relatively insignificant.Research limitations/implications: For economical production of aluminium and aluminium alloys die-castings it is important that the dies have a long working life. The replacement of a die is expensive in both: money and production time.Practical implications: Beside, the die design, the material selection and the process thermal stress fatigue course, which is the consequence of the working conditions, the inhomogeneous and to low initial temperature of the die, contribute to the cracks formation.Originality/value: It is clearly seen from the presented thermographs, that the required temperatures and homogeneity of the temperature field of the discussed case are not possible to reach without the changing both: the heating method and the die design. Therefore in the first stage a solution of the problem should be in changing of the position of heating and/or cooling channels, i.e. their closer shifting to the working surface of the die.

    Full Text Available The ethics of futures markets Formal futures markets were introduced in South Africa during the beginning of the 1990s. The aim of this article is to investigate the perception that futures markets amount to gambling practices and that they should as such not be tolerated within an economy. Evidence exists of futures markets being banned in countries such as Germany and France because of the belief that these markets foster gambling. The truth in this regard, however, is that futures markets serve as an imperative for the hedging o f price risks by means of futures contracts. Price risks have always been an inherent part o f the free market economy and as such the management of this kind of risk has been making stiff demands on markets in the economy. The manifestation and rapid growth of futures markets in South Africa show that economic needs are thus satisfied. - An important distinction between futures markets and gambling concerns the benefits accruing to society as a whole. It is shown that major differences exist between futures markets and gambling. The proper functioning of a formal futures market is acceptable both on moral and ethical grounds, and thus is also compatible with a Christian philosophy of life.

The aim of the study was to establish the relationship between locus of control and the work performance of black marketers in the life assurance industry. These constructs were selected by virtue of the lack of empirical research regarding the assumed relationship between them. The Locus of Control Scale of Schepers (1995 was used for measuring locus of control. Work performance was measured by the commission earned per month by the marketer, the number of policies generated by the marketer, as well as the percentage of lapsed policies. The relevant measurements were obtained in respect of a sample of 149 black marketing personnel. The results indicated a modest but statistically significant relationship between external locus of control and the work performance of black marketers. Opsomming Die doel van die studie was om die verband tussen lokus van beheer en die werksprestasie van swart bemarkers in die lewensversekeringsbedryf te bepaal. Hierdie konstrukte is gekies op grond van die gebrek aan empiriese navorsing rakende die veronderstelde verband tussen genoemde konstrukte. Die Lokus van Beheer-vraelys van Schepers (1995 is in die meting van lokus van beheer gebruik. Werksprestasie is aan die hand van kommissie per maand verdien, aantal polisse gegenereer deur 'n bemarker en die persentasie vervalde polisse, gemeet. Die tersaaklike metinge is verkry ten opsigte van 'n steekproef van 149 swart bemarkers.

  7. Big bang nucleosynthesis

    International Nuclear Information System (INIS)

    We present an overview of the standard model of big bang nucleosynthesis (BBN), which describes the production of the light elements in the early universe. The theoretical prediction for the abundances of D, 3He, 4He, and 7Li is discussed. We emphasize the role of key nuclear reactions and the methods by which experimental cross section uncertainties are propagated into uncertainties in the predicted abundances. The observational determination of the light nuclides is also discussed. Particular attention is given to the comparison between the predicted and observed abundances, which yields a measurement of the cosmic baryon content. The spectrum of anisotropies in the cosmic microwave background (CMB) now independently measures the baryon density to high precision; we show how the CMB data test BBN, and find that the CMB and the D and 4He observations paint a consistent picture. This concordance stands as a major success of the hot big bang. On the other hand, 7Li remains discrepant with the CMB-preferred baryon density; possible explanations are reviewed. Finally, moving beyond the standard model, primordial nucleosynthesis constraints on early universe and particle physics are also briefly discussed

  8. Big Rock Point

    International Nuclear Information System (INIS)

    The Big Rock Point Nuclear Plant is the second oldest operating nuclear power plant in the United States. Its 25-yr history is an embodiment of the history of commercial nuclear power. In some respects, its situation today - 5 yr past the midpoint of its design life - can provide operators of other nuclear plants a glimpse of where they will be in another decade. Construction on Big Rock Point began in 1960. It was completed just 2 1/2 yr later at a cost of $27 million. The plant is a General Electric (GE)-designed boiling water direct cycle, forced circulation, high power density reactor. Its construction was undertaken by Consumers Power under the third round of the U.S. Atomic Energy Commission's (AEC's) Power Demonstration Reactor Program. It was an advanced version of GE's Vallecitos boiling water reactor. The plant's fuel was GE's responsibility and, under contract with the AEC, it conducted a fuel research and development (RandD) program involving the plant. Although the plant was designed for research - its original electrical capacity was set at 50 MW(electric) - the unit was subsequently uprated to 69 MW(net electric). The original plant staff included only 44 people and minimal security. Mirroring the industry experience, the number of people on-site had quadrupled

    Constitution.The discussion is placed against the background of a so-called blank space in the 1996 Constitution. While the 1993 Constitution characterized South Africa as a "constitutional state", the 1996 does not contain such a characterization. It is argued in this paper that the process phrasing in section 1 (a ties in with a social democratic view of the state as an institution bringing about social change. The "state of affairs" phrasing of section 7(1 is, on the other hand, more in line with a liberal notion of a Rechtsstaat.The issue concerning what type of state South Africa is under the 1996 Constitution, will depend on which of the two poles in the above-mentioned dialectic the primary emphasis will be placed.Since the 1996 Constitution has been ratified by the Constitutional Court, it is regarded as extremely unlikely that the above-mentioned terminological problem will be rectified in future. Swanepoel provides a diagrammatic representation of the principle, values and objectives mentioned in the 1996 Constitution.Further research is envisaged concerning the possibility of developing a juridical model of reconciling the social-democratic and Rechtsstaat tendencies in the 1996 Constitution within the framework of a broader vision on the state’s task in bringing about justice.

    2010-04-01

    Nitriding of complex-shaped extrusion dies may result in non-uniform nitride layers and hence a required hardness may not be achieved in some regions of the bearing area. The present study is carried out to assess the effect of extrusion die profile on the characteristics and growth behavior of nitride layers so that the critical die design feature can be identified to enhance the uniformity of the nitride layer. For this purpose, AISI H13 steel samples have been manufactured with profiles similar to those of hot extrusion dies. The samples were then gas nitrided under controlled nitriding potential. The uniformity and depth of nitride layers have been investigated in terms of compound layer and total nitride case depth for selected die features. The results of this study indicated the need to include the effect of profile on the nitride layer for the optimal die design with improved service life.

    Full Text Available The historical Jesus, the Jesus movement and the birth of the church. The article focuses on the birth of the church. The point at which the church began its existence is located within the boundaries of fonnative Judaism. The parting of the ways is explained as a movement from faction to sect, to the eventual fonnation of the church in its own right as distinct from the synagogue. The historical Jesus should therefore not be seen as the founder of the church. However, the article argues that the relation of the life and death of the historical Jesus to the resurrection belief of the post-paschal Jesus movement constitutes the cradle of the church. This continuum between Jesus and New Testament Christendom is referred to by means of the Gennan phrase die Sache Jesu. Reconsideration of this trajectory results in the conviction that the vision and program of the historical Jesus cannot be neglected when one reflects on the nature of the church in the New Testament or on the vocation of the church through history to the present day. Two thought complexes form the kernel of die Sache Jesu: God's unbounded presence and the concept that everyone has unmediated and non-hierarchical access to the grace of God.

    Die-to-die reticle inspections are among the simplest and most sensitive reticle inspections because of the use of an identical-design neighboring-die for the reference image. However, this inspection mode can have two key disadvantages: (1) The location of the defect is indeterminate because it is unclear to the inspector whether the test or reference image is defective; and (2) nuisance and false defects from mask manufacturing noise and tool optical variation can limit the usable sensitivity. The use of a new sequencing approach for a die-to-die inspection can resolve these issues without any additional scan time, without sacrifice in sensitivity requirement, and with a manageable increase in computation load. In this paper we explore another approach for die-to-die inspections using a new method of defect processing and sequencing. Utilizing die-to-die double arbitration during defect detection has been proven through extensive testing to generate accurate placement of the defect in the correct die to ensure efficient defect disposition at the AIMS step. The use of this method maintained the required inspection sensitivity for mask quality as verified with programmed-defectmask qualification and then further validated with production masks comparing the current inspection approach to the new method. Furthermore, this approach can significantly reduce the total number of defects that need to be reviewed by essentially eliminating the nuisance and false defects that can result from a die-to-die inspection. This "double-win" will significantly reduce the effort in classifying a die-to-die inspection result and will lead to improved cycle times.

    This paper aims to explore key risks and extraneous factors influencing raw material availability and related consequences for the realization of future automotive power trains. Important raw materials for the electro mobility are presented followed by an evaluation of their future supply risk. A review of the current situation and a summary of expectations for future technological developments are presented. The current situation of political factors, access to resources and other important factors are then discussed, highlighting some of the major risks and their influence on up-take rates of alternative power train technologies. Specifically the specific relationships between demand and supply side for specific rare earth elements and their effects on price development is investigated and suggests how these factors might influence existing relationships within the automotive industry. The paper concludes with suggestions for alternative strategies for specific groups within the automotive value chain to mitigate those risks. (orig.)

    Full Text Available Ideological norm replacement and the Afrikaans desk dictionary of the ninetiesIn South Africa the past decade has been marked by extensive sociopolitical changes and by concomitant linguistic changes. These changes may be regarded as instances of norm replacement - a process during the course of which a norm or a set of norms is gradually replaced by another norm or set of norms. It is maintained that the standard synchronic dictionaries of a language not only have the obligation to reflect lexicalised norm replacements, but also to make projections with regard to future use. Two standard synchronic desk dictionaries of Afrikaans, namely the eighth edition of Verklarende Afrikaanse Woordeboek (1992 and the third edition of Verklarende Handwoordeboek van die Afrikaanse Taal (1994 are explored with special regard to their reflection of norm replacements within the domains of race and political ideology. It is shown that the compilers of these dictionaries consciously and sincerely aimed at removing all racial bias but that they failed to record the diversity of meaning within the political lexicon and the semantic shifts which have occurred within that lexicon during the past decade.

    It is shown in this paper that minisuperspace quantization of homogeneous and isotropic geometries with phantom scalar fields, when examined in the light of the Bohm-de Broglie interpretation of quantum mechanics, does not eliminate, in general, the classical big rip singularity present in the classical model. For some values of the Hamilton-Jacobi separation constant present in a class of quantum state solutions of the Wheeler-De Witt equation, the big rip can be either completely eliminated or may still constitute a future attractor for all expanding solutions. This is contrary to the conclusion presented in [M. P. Dabrowski, C. Kiefer, and B. Sandhofer, Phys. Rev. DPRVDAQ1550-7998 74, 044022 (2006).10.1103/PhysRevD.74.044022], using a different interpretation of the wave function, where the big rip singularity is completely eliminated (“smoothed out”) through quantization, independently of such a separation constant and for all members of the above mentioned class of solutions. This is an example of the very peculiar situation where different interpretations of the same quantum state of a system are predicting different physical facts, instead of just giving different descriptions of the same observable facts: in fact, there is nothing more observable than the fate of the whole Universe.

God is die hoogste, die volheid van syn, en by die laere synsniveaus is daar steeds 'n verdere verwydering van hierdie synsvolmaaktheid in die rigting van absolute afwesigheid van syn. Hierdie synshiërargie is volgens die vorm-materieskema opgebou. Die materie in die hoëre synslaag word vorm vir die laere, of omgekeerd: die vorm van die laere is die materie vir die hoëre dinge. God is absoluut suiwer vorm of wet (essensie. Die vorme van die dinge is die goddelike wet (genoem exemplar, similitudo, ratio, verbum of imago wat deur God daarin geskape is.

God word deur Thomas die causa effiaiens en exemplaris genoem. Die verhouding tussen Skepper en geskape werklikheid is dus dié van oorsaak en gevolg. As gevolg van sy wetsidee word daar deur Thomas dus nie duidelik tussen Skepper en skepping onderskei nie, want skepping beteken volgens hom onder andere dat God iets goddeliks (die wet in die dinge lê. Via die goddelike wet in die dinge ingeskape, is daar 'n sekere kontinuiteit tussen God en kosmos.

  12. SETI as a part of Big History

    Science.gov (United States)

    Maccone, Claudio

    2014-08-01

    Big History is an emerging academic discipline which examines history scientifically from the Big Bang to the present. It uses a multidisciplinary approach based on combining numerous disciplines from science and the humanities, and explores human existence in the context of this bigger picture. It is taught at some universities. In a series of recent papers ([11] through [15] and [17] through [18]) and in a book [16], we developed a new mathematical model embracing Darwinian Evolution (RNA to Humans, see, in particular, [17] and Human History (Aztecs to USA, see [16]) and then we extrapolated even that into the future up to ten million years (see 18), the minimum time requested for a civilization to expand to the whole Milky Way (Fermi paradox). In this paper, we further extend that model in the past so as to let it start at the Big Bang (13.8 billion years ago) thus merging Big History, Evolution on Earth and SETI (the modern Search for ExtraTerrestrial Intelligence) into a single body of knowledge of a statistical type. Our idea is that the Geometric Brownian Motion (GBM), so far used as the key stochastic process of financial mathematics (Black-Sholes models and related 1997 Nobel Prize in Economics!) may be successfully applied to the whole of Big History. In particular, in this paper we derive Big History Theory based on GBMs: just as the GBM is the “movie” unfolding in time, so the Statistical Drake Equation is its “still picture”, static in time, and the GBM is the time-extension of the Drake Equation. Darwinian Evolution on Earth may be easily described as an increasing GBM in the number of living species on Earth over the last 3.5 billion years. The first of them was RNA 3.5 billion years ago, and now 50

  13. Big Bounce Genesis

    Li, Changhong; Cheung, Yeuk-Kwan E

    2014-01-01

    We report on the possibility to use dark matter mass and its interaction cross section as a smoking gun signal of the existence of a big bounce at the early stage in the evolution of our currently observed universe. A model independent study of dark matter production in the contraction and expansion phases of the bounce universe reveals a new venue for achieving the observed relic abundance in which a significantly smaller amount of dark matter--compared to the standard cosmology--is produced and survives until today, diluted only by the cosmic expansion since the radiation dominated era. Once DM mass and its interaction strength with ordinary matter are determined by experiments, this alternative route becomes a signature of the bounce universe scenario.

  14. A matrix big bang

    International Nuclear Information System (INIS)

    The light-like linear dilaton background represents a particularly simple time-dependent 1/2 BPS solution of critical type-IIA superstring theory in ten dimensions. Its lift to M-theory, as well as its Einstein frame metric, are singular in the sense that the geometry is geodesically incomplete and the Riemann tensor diverges along a light-like subspace of codimension one. We study this background as a model for a big bang type singularity in string theory/M-theory. We construct the dual Matrix theory description in terms of a (1+1)-d supersymmetric Yang-Mills theory on a time-dependent world-sheet given by the Milne orbifold of (1+1)-d Minkowski space. Our model provides a framework in which the physics of the singularity appears to be under control

In addition, heterogenous integration enabled by 3D technology can also result in innovative designs for future microprocessors. This book first provides a brief introduction to this emerging technology, and then presents a variety of approaches to design

  2. DPF Big One

    International Nuclear Information System (INIS)

    At its latest venue at Fermilab from 10-14 November, the American Physical Society's Division of Particles and Fields meeting entered a new dimension. These regular meetings, which allow younger researchers to communicate with their peers, have been gaining popularity over the years (this was the seventh in the series), but nobody had expected almost a thousand participants and nearly 500 requests to give talks. Thus Fermilab's 800-seat auditorium had to be supplemented with another room with a video hookup, while the parallel sessions were organized into nine bewildering streams covering fourteen major physics topics. With the conventionality of the Standard Model virtually unchallenged, physics does not move fast these days. While most of the physics results had already been covered in principle at the International Conference on High Energy Physics held in Dallas in August (October, page 1), the Fermilab DPF meeting had a very different atmosphere. Major international meetings like Dallas attract big names from far and wide, and it is difficult in such an august atmosphere for young researchers to find a receptive audience. This was not the case at the DPF parallel sessions. The meeting also adopted a novel approach, with the parallels sandwiched between an initial day of plenaries to set the scene, and a final day of summaries. With the whole world waiting for the sixth ('top') quark to be discovered at Fermilab's Tevatron protonantiproton collider, the meeting began with updates from Avi Yagil and Ronald Madaras from the big detectors, CDF and DO respectively. Although rumours flew thick and fast, the Tevatron has not yet reached the top, although Yagil could show one intriguing event of a type expected from the heaviest quark

  3. The Born Rule Dies

    CERN Document Server

    Page, Don N

    2009-01-01

    The Born rule may be stated mathematically as the rule that probabilities in quantum theory are expectation values of a complete orthogonal set of projection operators. This rule works for single laboratory settings in which the observer can distinguish all the different possible outcomes corresponding to the projection operators. However, theories of inflation suggest that the universe may be so large that any laboratory, no matter how precisely it is defined by its internal state, may exist in a large number of very distantly separated copies throughout the vast universe. In this case, no observer within the universe can distinguish all possible outcomes for all copies of the laboratory. Then normalized probabilities for the local outcomes that can be locally distinguished cannot be given by the expectation values of any projection operators. Thus the Born rule dies and must be replaced by another rule for observational probabilities in cosmology. The freedom of what this new rule is to be is the measure pr...

  4. Modeling and Analysis in Marine Big Data: Advances and Challenges

    2015-01-01

    Full Text Available It is aware that big data has gathered tremendous attentions from academic research institutes, governments, and enterprises in all aspects of information sciences. With the development of diversity of marine data acquisition techniques, marine data grow exponentially in last decade, which forms marine big data. As an innovation, marine big data is a double-edged sword. On the one hand, there are many potential and highly useful values hidden in the huge volume of marine data, which is widely used in marine-related fields, such as tsunami and red-tide warning, prevention, and forecasting, disaster inversion, and visualization modeling after disasters. There is no doubt that the future competitions in marine sciences and technologies will surely converge into the marine data explorations. On the other hand, marine big data also brings about many new challenges in data management, such as the difficulties in data capture, storage, analysis, and applications, as well as data quality control and data security. To highlight theoretical methodologies and practical applications of marine big data, this paper illustrates a broad view about marine big data and its management, makes a survey on key methods and models, introduces an engineering instance that demonstrates the management architecture, and discusses the existing challenges.

    In 1996 Europe started the process of liberalising the electricity sector and of regulating the natural monopoly of the grid. This journey turned out to be more complex and drawn out than originally thought, with results not always meeting expectations. No wonder that the academic and political debate is still going on and is currently more heated than before. Given the huge importance of electricity for every developed nation and the big economic interests at stake, we do not expect this trend to slow down. This interdisciplinary investigation, however, does not intend to follow the beaten path of the controversy guided by interest groups. Instead, we looked for issues that are important for the effectiveness of future incentive-based regulation to ensure non-discriminatory competition before and behind the electricity grid. Chapter 1 reviews the debates and identifies the specific questions for this book. Since much of our topic involves legal considerations, we focused predominantly on the German situation without losing sight of the European drivers and learning experiences. But we clearly had to leave out many questions, briefly reviewed in Chapter 1.4, and set priorities for our investigation. Therefore we tried to understand some basic questions of electricity grid technology and its implications for regulation (2.1 with App. A), the history of regulation (2.2), the thinking in regulatory design where legal and economic aspects overlap (2.3), especially investigating the information asymmetry between regulators and regulated industry in the specific context of yardstick competition- based regulation (2.4) and the trade-off between cost efficiency and high standards of security of supply (2.5). In Chapter 3, we looked at the specific issues that we identified as emerging from the regulatory evolution: who will decide about future demand estimates, guiding investment decisions (3.1), the new model needed for innovation (3.2) and the security of supply (3

  19. From big bang to big crunch and beyond

    International Nuclear Information System (INIS)

    We study a quotient Conformal Field Theory, which describes a 3+1 dimensional cosmological spacetime. Part of this spacetime is the Nappi-Witten (NW) universe, which starts at a 'big bang' singularity, expands and then contracts to a 'big crunch' singularity at a finite time. The gauged WZW model contains a number of copies of the NW spacetime, with each copy connected to the preceding one and to the next one at the respective big bang/big crunch singularities. The sequence of NW spacetimes is further connected at the singularities to a series of non-compact static regions with closed timelike curves. These regions contain boundaries, on which the observables of the theory live. This suggests a holographic interpretation of the physics. (author)

    We point out a new phenomenon which seems to be generic in 4d effective theories of scalar fields coupled to Einstein gravity, when applied to cosmology. A lift of such theories to a Weyl-invariant extension allows one to define classical evolution through cosmological singularities unambiguously, and hence construct geodesically complete background spacetimes. An attractor mechanism ensures that, at the level of the effective theory, generic solutions undergo a big crunch/big bang transition...

For free fields in our construction there is no particle production from the incoming adiabatic vacuum. When interacti...

The key was identifying a sufficient number of finite, Weyl-invariant conserved quantities to uniquely match the fundamental cosmological degrees of freedom across the transition. In so ...

    Objective Electronic health records (EHRs) may contain infomarkers that identify patients near the end of life for whom it would be appropriate to shift care goals to palliative care. Discovery and use of such infomarkers could be used to conduct effectiveness research that ultimately could help to reduce the monumental costs for dying care. Our aim was to identify changes in the plans of care that represented infomarkers, which signaled the transition of care goals from non-palliative care goals to those consistent with palliative care. Methods Using an existing electronic health record database generated during a two-year, longitudinal study of 9 diverse medical-surgical units from 4 Midwest hospitals and a known group approach, we evaluated the patient care episodes for 901 patients who died (mean age=74.5±14.6 years). We used ANOVA and Tukey’s post-hoc tests to compare patient groups. Results We identified 11 diagnoses, including Death Anxiety and Anticipatory Grieving, whose addition to the care plan, some of which also occurred with removal of non-palliative care diagnoses, represent infomarkers of transition to palliative care goals. There were four categories of patients, those who had: no infomarkers on plans (n=507); infomarkers added on the admission plan (n=194); infomarkers added on a post admission plan (minor transitions, n=109), and infomarkers added and non-palliative care diagnoses removed on a post admission plan (major transition, n=91). Age, length of stay, and pain outcomes differed significantly for these four categories of patients. Significance of Results EHRs contain pertinent infomarkers that if confirmed in future studies could be used for timely referral to palliative care for improved focus on comfort outcomes and to identify palliative care subjects from data repositories for to conduct big data research, comparative effectiveness studies, and health services research.

    It was only after James P. Lovette's death, in 2006, that I discovered that the twenty-four-year-old colleague and friend with whom I had spent so many afternoons debating issues in organ transplantation had been the first successful child heart transplantee in the world and one of the longest-living survivors of a second transplant. During the years we met, he never even hinted at the fact that three different hearts had beaten in his chest. The revelation that his life had been an almost uninterrupted chain of medical challenges suddenly made me appreciate his quirkiness in a whole new light. Organ transplantation crudely exemplifies a traditional moral dilemma between means and ends: in order to save a life, someone else has to die. Bioethicists involved in this field have the role of identifying the ethical issues surrounding organ donation and helping others to argue in an intelligible and convincing way. In my view, bioethicists have the obligation to foster a discussion as open and transparent as possible on these matters. Still, I sometimes fear that I may be helping to cause unnecessary harms to potential recipients who are desperately waiting for a vital organ. Scholars would be chillingly cold if their quest for truth systematically came at the cost of lives lost. Every life can be meaningful and provide meaning to many others. This is true even with organ recipients, who often have short lives full of considerable suffering. PMID:25231665

    The worldwide economic recession and the concomitant limited stock of finances have had an influence on the available money of every household and have also inhibited the improvement of socio-economic conditions and medicine. The Reconstruction and Development Programme (RDP) has the objective of improving the living conditions of the people with regard to housing, education, training and health care. The latter seems to be a major problem which has to be addressed with the emphasis on the preventive and promotional aspects of health care. A comprehensive health care system did not come into being property in the past because of the maldistribution of health care services, personnel and differences in culture and health care beliefs and values. The question that now arises, is how to render a quality health care service within the constraints of inadequate financing and resources. A comprehensive literature study has been done with reference to quality health care and financing followed by a survey of existing health services and finances. Recommendations are made about minimum requirements to be accepted if one were to adapt rather than die in terms of the provision of healthcare: the decentralization and rationalization of the administration of health care, the stress on and realization of effective and efficient primary health care, the acceptance of participative management in health providing organizations, the provision of financial management training for health care managers and the application of management accounting principles for the improvement of the efficiency and effectiveness of management.

    The diesel engine is the most common powertrain in commercial applications, and will retain that position for the foreseeable future. In order to meet future emission standards, a wide variety of solutions within combustion process control, exhaust gas aftertreatment, air and injection systems have been developed. The development of common rail injection systems for trucks with 2000 and 2200 bar injection pressure increases the opportunities for internal engine emissions reductions. The systems are designed for medium-duty and heavy-duty applications, on-highway (on-HW) and Off-highway (off-HW). Besides increasing the injection pressure this system features high efficiency in hydraulic pressure generation and injection, making a direct contribution to reducing fuel consumption. To meet even greater requirements, a system with an injection pressure of 2500 bar is under development. As an indicator for the hydraulic efficiency of an injector, the ''effective injection pressure'' is derived. This indicator allows for a uniform rating of different injector concepts. Software functions contribute to the fulfillment of the system requirements over lifetime. An engine speed based function calibrates the pilot injection quantity during low idle operation for on- and off-highway applications. The increase in system pressure results in increased loads for the components. A calibration function for the pump delivery characteristics minimizes pressure overshoots and ensures the pressure control dynamics over lifetime. (orig.)

    Full Text Available Die vrye wêreld het sedert die oorloggedwonge opskorting van die goudstandaard in 1914, ’n groot agteruitgang in die internasionale betalingsmeganisme beleef. Hoewel die inter- nasionale goudstandaard in die laaste helfte van die twintiger- jare herstel is, was meeste lande nie langer gedwee om hulle aan die monetêre dissipline van dié stelsel te onderwerp nie en vind ons dat die een land na die ander onder die druk van die depressie in die dertigerjare die goudstandaard laat vaar het. Die Verenigde State van Amerika was die enigste uitson- dering. Geleidelik moes wisselkoersstabiliteit en die vrye inter­ nasionale betalingsverkeer vir wisselkoersmanipulasie en valu- tabeheer plek maak. Hierdie transformasie was ’n weerspieë- ling van die sterker opkoms van ekonomiese nasionalisme en die begeerte van die onderskeie lande om elkeen vir homself die beste voordeel in die internasionale ekonomiese en finan- siële terrein toe te eien. Die daarstelling van die Internasionale Monetêre Fonds te Bretton Woods in 1944, was ’n simptoom van die wêreldwye kommer oor die vooroorlogse neigings op monetêre gebied en terselfdertyd ’n poging om meer dissi­ pline in die internasionale betalingsverkeer te skep. Feit is egter dat ondanks sy positiewe resultate op sommige gebiede, die Internasionale Monetêre Fonds nie heeltemal 'n geskikte substituut vir die goudstandaard daargestel het nie. Wat meer is, die skok van die internasionale monetêre steurnisse word nog steeds deur die lande met die internasionale geldeenhede, naamlik die pond sterling en die dollar ondervind.

    Gordan Krnjaic

    2015-12-01

    Full Text Available In a popular class of models, dark matter comprises an asymmetric population of composite particles with short range interactions arising from a confined nonabelian gauge group. We show that coupling this sector to a well-motivated light mediator particle yields efficient darkleosynthesis, a dark-sector version of big-bang nucleosynthesis (BBN, in generic regions of parameter space. Dark matter self-interaction bounds typically require the confinement scale to be above ΛQCD, which generically yields large (≫MeV/dark-nucleon binding energies. These bounds further suggest the mediator is relatively weakly coupled, so repulsive forces between dark-sector nuclei are much weaker than Coulomb repulsion between standard-model nuclei, which results in an exponential barrier-tunneling enhancement over standard BBN. Thus, darklei are easier to make and harder to break than visible species with comparable mass numbers. This process can efficiently yield a dominant population of states with masses significantly greater than the confinement scale and, in contrast to dark matter that is a fundamental particle, may allow the dominant form of dark matter to have high spin (S≫3/2, whose discovery would be smoking gun evidence for dark nuclei.

    Big bang nucleosynthesis (BBN) describes the production of the lightest nuclides via a dynamic interplay among the four fundamental forces during the first seconds of cosmic time. A brief overview of the essentials of this physics is given, and new calculations presented of light-element abundances through 6Li and 7Li, with updated nuclear reactions and uncertainties including those in the neutron lifetime. Fits are provided for these results as a function of baryon density and of the number of neutrino flavors Nν. Recent developments are reviewed in BBN, particularly new, precision Planck cosmic microwave background (CMB) measurements that now probe the baryon density, helium content, and the effective number of degrees of freedom Neff. These measurements allow for a tight test of BBN and cosmology using CMB data alone. Our likelihood analysis convolves the 2015 Planck data chains with our BBN output and observational data. Adding astronomical measurements of light elements strengthens the power of BBN. A new determination of the primordial helium abundance is included in our likelihood analysis. New D/H observations are now more precise than the corresponding theoretical predictions and are consistent with the standard model and the Planck baryon density. Moreover, D/H now provides a tight measurement of Nν when combined with the CMB baryon density and provides a 2 σ upper limit Nνdata. In contrast with D/H and 4He, 7Li predictions continue to disagree with observations, perhaps pointing to new physics. This paper concludes with a look at future directions including key nuclear reactions, astronomical observations, and theoretical issues.

Finally nowaday (still?) speculative theories are sketched: Theories of the grand unification of the interactions, supersymmetry, the string theory, and additional dimensions of the space-time. No greater mathematical or physical knowledge is presupposed; the book is also suited for abiturients and students of the first semesters.

  17. Quantenfische die Stringtheorie und die Suche nach Weltformel

    2011-01-01

    Lässt sich das Verhalten aller Dinge, von den kleinsten Teilchen bis zum Universum, einheitlich beschreiben? Der heißeste Kandidat für die Entwicklung einer Weltformel, die alle physikalischen Phänomene erklären kann, ist die Stringtheorie. Sollte sie sich als richtig erweisen, so würde das unser Verständnis über den Ursprung der Naturgesetze dramatisch verändern. Denn das von uns beobachtete Universum wäre dann vermutlich eine winzige Blase in einem viel größeren Gebilde, dem Multiversum. Um die Stringtheorie und die Idee des Multiversums plausibel zu machen, greift der international bekannte theoretische Physiker Dieter Lüst auf ein Modell zurück: das Leben von Fischen in einem Teich. Eines Tages gelingt es den Fischen, die kleinsten Teilchen zu identifizieren, aus denen alles im Fischteich besteht - eingeschlossen sie selbst. Sie nennen diese Urbausteine Quantenfische, da ihr Verhalten nahelegt, dass sie auch eine Art von Lebewesen sind. Doch der ersten folgt eine weitere Entdeckung der Fisch...

  18. 'Big data', Hadoop and cloud computing in genomics.

    2013-10-01

    Since the completion of the Human Genome project at the turn of the Century, there has been an unprecedented proliferation of genomic sequence data. A consequence of this is that the medical discoveries of the future will largely depend on our ability to process and analyse large genomic data sets, which continue to expand as the cost of sequencing decreases. Herein, we provide an overview of cloud computing and big data technologies, and discuss how such expertise can be used to deal with biology's big data sets. In particular, big data technologies such as the Apache Hadoop project, which provides distributed and parallelised data processing and analysis of petabyte (PB) scale data sets will be discussed, together with an overview of the current usage of Hadoop within the bioinformatics community.

    Full Text Available The objective of this paper is to set a framework for examining the conditions under which the big data can create long-term profitability through developing dynamic operations and digital supply networks in supply chain. We investigate the extent to which big data analytics has the power to change the competitive landscape of industries that could offer operational, strategic and competitive advantages. This paper is based upon a qualitative study of the convergence of predictive analytics and big data in the field of supply chain management. Our findings indicate a need for manufacturers to introduce analytics tools, real-time data, and more flexible production techniques to improve their productivity in line with the new business model. By gathering and analysing vast volumes of data, analytics tools help companies to resource allocation and capital spends more effectively based on risk assessment. Finally, implications and directions for future research are discussed.

  20. What's the Big Idea? Seeking to Top Apollo

    2012-01-01

    Human space flight has struggled to find its soul since Apollo. The astounding achievements of human space programs over the 40 years since Apollo have failed to be as iconic or central to society as in the 1960s. The paper proffers a way human space flight could again be associated with a societal Big Idea. It describes eight societal factors that have irrevocably changed since Apollo; then analyzes eight other factors that a forward HSF Big Idea would have to fit. The paper closes by assessing the four principal options for HSF futures against those eight factors. Robotic and human industrialization of geosynchronous orbit to provide unlimited, sustainable electrical power to Earth is found to be the best candidate for the next Big Idea.

    Big data has emerged as the next technological revolution in IT industry after cloud computing and the Internet of Things. With the development of climate observing systems, particularly satellite meteorological observation and high-resolution climate models, and the rapid growth in the volume of climate data, climate prediction is now entering the era of big data. The application of big data will provide new ideas and methods for the continuous development of climate prediction. The rapid integration, cloud storage, cloud computing, and full-sample analysis of massive climate data makes it possible to understand climate states and their evolution more objectively, thus predicting the future climate more accurately. This paper describes the application status of big data in operational climate prediction in China; it analyzes the key big data technologies, discusses the future development of climate prediction operations from the perspective of big data, speculates on the prospects for applying climatic big data in cloud computing and data assimilation, and puts forward the notion of big data-based super-ensemble climate prediction methods and computerbased deep learning climate prediction methods.

  6. A Novel Burnable Absorber Concept for PWR: BigT (Burnable Absorber-Integrated Guide Thimble)

    International Nuclear Information System (INIS)

    This paper presents the essential BigT design concepts and its lattice neutronic characteristics. Neutronic performance of a newly-proposed BA concept for PWR named BigT is investigated in this study. Preliminary lattice analyses of the BigT absorber-loaded WH 17x17 fuel assembly show a high potential of the concept as it performs relatively well in comparison with commercial burnable absorber technologies, especially in managing reactivity depletion and peaking factor. A sufficiently high control rod worth can still be obtained with the BigT absorbers in place. It is expected that with such performance and design flexibilities, any loading pattern and core management objective, including a soluble boron-free PWR, can potentially be fulfilled with the BigT absorbers. Future study involving full 3D reactor core simulations with the BigT absorbers shall hopefully verify this hypothesis. A new burnable absorber design for Pressurized Water Reactor (PWR) named 'Burnable absorber-Integrated control rod Guide Thimble' (BigT) was recently proposed. Unlike conventional burnable absorber (BA) technologies, the BigT integrates BA materials directly into the guide thimble but still allows insertion of control rod (CR). In addition, the BigT offers a variety of design flexibilities such that any loading pattern and core management objective can potentially be fulfilled

    The authors examine the question of whether and to what extent globalization changes in the future. For this purpose, an expert survey is carried out. The results of this expert surveys are described in the contribution under consideration: (1) The vast majority of climate scientists says that limiting global warming to two degrees celsius only is possible if the developed industrial countries reduce their emissions by 80 % compared to the year 1990; (2) This inevitably requires interventions of the policy for sustainable management; (3) Despite the economic and financial crisis the policy shall not ease its ambitious targets in the medium term; (4) The threat of global warming is a global problem. The solution of this problem at political level requires a more advanced form of 'global governance'; (5) A significant increase in the petroleum price may affect the globally distributed industrial 'settlement structures' and the configuration of logistics networks. A possible adaptation may consist in multistage distribution systems with regional, customer-oriented stocks; (6) A stronger focus of companies to a low-polluting, sustainable business can be facilitated and supported by financial incentives; (7) It is not expected that professional buyers of companies do not sacrifice price advantages in low-wage countries; (8) Scale effects in the production by special factories result in a continuation of the current 'production footprints' even if this model significantly increases the transport intensity of the economy due to the longer distance between the place of production and the place of consumption; (9) In the logistics presumable there exists any other single measure to eliminate many pollutants such as the replacement of air cargo by sea freight; (10) Economic-historically, globalization has developed very quickly. The experts disagree on whether globalization slows down or whether the globalization changes at a constant speed.

    Radiation therapy is a first-line treatment option for localized prostate cancer and radiation-induced normal tissue damage are often the main limiting factor for modern radiotherapy regimens. Conversely, under-dosing of target volumes in an attempt to spare adjacent healthy tissues limits the likelihood of achieving local, long-term control. Thus, the ability to generate personalized data-driven risk profiles for radiotherapy outcomes would provide valuable prognostic information to help guide both clinicians and patients alike. Big data applied to radiation oncology promises to deliver better understanding of outcomes by harvesting and integrating heterogeneous data types, including patient-specific clinical parameters, treatment-related dose–volume metrics, and biological risk factors. When taken together, such variables make up the basis for a multi-dimensional space (the “RadoncSpace”) in which the presented modeling techniques search in order to identify significant predictors. Herein, we review outcome modeling and big data-mining techniques for both tumor control and radiotherapy-induced normal tissue effects. We apply many of the presented modeling approaches onto a cohort of hypofractionated prostate cancer patients taking into account different data types and a large heterogeneous mix of physical and biological parameters. Cross-validation techniques are also reviewed for the refinement of the proposed framework architecture and checking individual model performance. We conclude by considering advanced modeling techniques that borrow concepts from big data analytics, such as machine learning and artificial intelligence, before discussing the potential future impact of systems radiobiology approaches.

Hierdie vernuwing in die kurrikulum is met gemengde reaksies begroet. Terwyl sommige onderwysers dit met entoesiasme onderrig, is baie gekant teen die onderrig van evolusie. Die artikel is gebaseer op ’n navorsingsprojek waarby 255 onderwysers betrek is. Vraelyste is gebruik om kwalitatiewe data, wat vir diskoers ontleed is, in te samel. Die diskoers van die onderwysers het getoon dat ’n groot getal van hulle nie hul onderrigopdrag kan versoen met hul geloof nie en konsepte oor evolusie as ‘feite’ verduidelik, maar seker maak dat evolusie as ’n teorie gediskrediteer word. Dit het verreikende implikasies vir sowel onderwyseropleiding as kurrikulumontwikkeling. Konseptuele veranderingsteorie word as ’n lens gebruik om na hierdie problematiek te kyk. Challenges in the teaching of evolution in the life sciences classroom. In this article the authors report on research that was conducted about teachers’ views on evolution, which was introduced as a theme in the school life sciences curriculum in 2008. This innovation in the curriculum has been met with mixed reactions. Whereas some teachers embrace this new theme, many teachers are opposed to the teaching of evolution. The article reports on an inquiry that was conducted amongst 255 teachers and in which survey questionnaires were used to collect qualitative data, which was analysed for its discourse. The discourse of the teachers shows that many of them cannot reconcile their religious faith with their teaching and that they may teach the ‘facts’ of evolution, but make sure that they discredit evolution as a theory. This raises serious concerns about teacher education and curriculum development. The authors examine these issues through the lens of conceptual change

    Starting from the Janus solution and its gauge theory dual, we obtain the dual gauge theory description of the cosmological solution by procedure of the double anaytic continuation. The coupling is driven either to zero or to infinity at the big-bang and big-crunch singularities, which are shown to be related by the S-duality symmetry. In the dual Yang-Mills theory description, these are non singular at all as the coupling goes to zero in the N=4 Super Yang-Mills theory. The cosmological sing...

  7. Turning big bang into big bounce: II. Quantum dynamics

    International Nuclear Information System (INIS)

    We analyze the big bounce transition of the quantum Friedmann-Robertson-Walker model in the setting of the nonstandard loop quantum cosmology (LQC). Elementary observables are used to quantize composite observables. The spectrum of the energy density operator is bounded and continuous. The spectrum of the volume operator is bounded from below and discrete. It has equally distant levels defining a quantum of the volume. The discreteness may imply a foamy structure of spacetime at a semiclassical level which may be detected in astro-cosmo observations. The nonstandard LQC method has a free parameter that should be fixed in some way to specify the big bounce transition.

    Full Text Available Kuslande het ’n eenmalige geleentheid om by die Verenigde Nasies (VN aansoek te doen om ’n uitgebreide maritieme gebied, indien hul wetenskaplik kan toon dat die voet van die kontinentale helling (VKH buite hul soewereine 200 seemyl eksklusiewe ekonomiese sone gele¨e is. Die VN definieer geomorfologies die VKH as die kromme van maksimale buiging tussen die afplattende kontinentale helling en die bodem van die diepsee. In hierdie artikel word daar getoon hoe gediskretiseerde tegnieke uit differensiaalmeetkunde suksesvol gebruik kan word om die VKH benaderd uit satelliet seebodem dieptedata te bepaal, sonder om van data gladstrykingstegnieke gebruik te maak. Hierdie differensiaalmeetkundige benadering is ’n alternatief tot ’n huidige, wyd-gebruikte tegniek vir die bepaling van die VKH en toon dat internasionale spekulasie oor die opportunisme van hierdie tegniek bloot vanuit ’n geomorfologiese perspektief geregverdig mag wees. Die numeriese resultate wat verkry word, is ’n wetenskaplik verantwoordbare aanwyser ten opsigte van die moontlike ligging van die VKH rondom die Suid-Afrikaanse kus.

    We are experiencing astonishing developments in the areas of big data and artificial intelligence. They follow a pattern that we have now been observing for decades: according to Moore's Law,the performance and efficiency in the area of elementary arithmetic operations increases a thousand-fold every 20 years. Although we have not achieved the status where in the singular sense machines have become as "intelligent" as people, machines are becoming increasingly better. The Internet of Things has again helped to massively increase the efficiency of machines. Big data and suitable analytics do the same. If we let these processes simply continue, our civilization may be endangerd in many instances. If the "containment" of these processes succeeds in the context of a reasonable political global governance, a worldwide eco-social market economy, andan economy of green and inclusive markets, many desirable developments that are advantageous for our future may result. Then, at some point in time, the constant need for more and faster innovation may even stop. However, this is anything but certain. We are facing huge challenges. PMID:26141245

    2005-11-01

    The Big Sky Carbon Sequestration Partnership, led by Montana State University, is comprised of research institutions, public entities and private sectors organizations, and the Confederated Salish and Kootenai Tribes and the Nez Perce Tribe. Efforts under this Partnership in Phase I fall into four areas: evaluation of sources and carbon sequestration sinks that will be used to determine the location of pilot demonstrations in Phase II; development of GIS-based reporting framework that links with national networks; designing an integrated suite of monitoring, measuring, and verification technologies and assessment frameworks; and initiating a comprehensive education and outreach program. The groundwork is in place to provide an assessment of storage capabilities for CO2 utilizing the resources found in the Partnership region (both geological and terrestrial sinks), that would complement the ongoing DOE research agenda in Carbon Sequestration. The region has a diverse array of geological formations that could provide storage options for carbon in one or more of its three states. Likewise, initial estimates of terrestrial sinks indicate a vast potential for increasing and maintaining soil C on forested, agricultural, and reclaimed lands. Both options include the potential for offsetting economic benefits to industry and society. Steps have been taken to assure that the GIS-based framework is consistent among types of sinks within the Big Sky Partnership area and with the efforts of other DOE regional partnerships. The Partnership recognizes the critical importance of measurement, monitoring, and verification technologies to support not only carbon trading but all policies and programs that DOE and other agencies may want to pursue in support of GHG mitigation. The efforts in developing and implementing MMV technologies for geological sequestration reflect this concern. Research is also underway to identify and validate best management practices for soil C in the

    Ocean Networks Canada operates two large undersea observatories that collect, archive, and deliver data in real time over the Internet. These data contribute to our understanding of the complex changes taking place on our ocean planet. Ocean Networks Canada's VENUS was the world's first cabled seafloor observatory to enable researchers anywhere to connect in real time to undersea experiments and observations. Its NEPTUNE observatory is the largest cabled ocean observatory, spanning a wide range of ocean environments. Most recently, we installed a new small observatory in the Arctic. Together, these observatories deliver "Big Data" across many disciplines in a cohesive manner using the Oceans 2.0 data management and archiving system that provides national and international users with open access to real-time and archived data while also supporting a collaborative work environment. Ocean Networks Canada operates these observatories to support science, innovation, and learning in four priority areas: study of the impact of climate change on the ocean; the exploration and understanding the unique life forms in the extreme environments of the deep ocean and below the seafloor; the exchange of heat, fluids, and gases that move throughout the ocean and atmosphere; and the dynamics of earthquakes, tsunamis, and undersea landslides. To date, the Ocean Networks Canada archive contains over 130 TB (collected over 7 years) and the current rate of data acquisition is ~50 TB per year. This data set is complex and diverse. Making these "Big Data" accessible and attractive to users is our priority. In this presentation, we share our experience as a "Big Data" institution where we deliver simple and multi-dimensional calibrated data cubes to a diverse pool of users. Ocean Networks Canada also conducts extensive user testing. Test results guide future tool design and development of "Big Data" products. We strive to bridge the gap between the raw, archived data and the needs and

    We show there exist smooth asymptotically anti-de Sitter initial data which evolve to a big crunch singularity in a low energy supergravity limit of string theory. This opens up the possibility of using the dual conformal field theory to obtain a fully quantum description of the cosmological singularity. A preliminary study of this dual theory suggests that the big crunch is an endpoint of evolution even in the full string theory. We also show that any theory with scalar solitons must have negative energy solutions. The results presented here clarify our earlier work on cosmic censorship violation in N=8 supergravity.

Volgens die outeur staan die vrae oor God, Jesus, die mens en die aarde in die sentrum van belangstelling en oorheers dit in ’n groot mate die teologiese debat. Die opkoms van die moderne aggressiewe ateïsme, die wetenskaplike navorsing oor die historiese Jesus, die groeiende vrae oor die mens en die menslike samelewing, asook die dreigende ekologiese krisis op aarde, sorg vir nuwe debatte van ongekende omvang. Die outeur bespreek hierdie debatte oorsigtelik, met kritiek waar nodig, en sluit af met enkele rigtingwysers van wat hy as ‘goeie teologie’ verstaan.In this article attention is paid to some modern discourses in theology today. According to the author the questions about God, Jesus, man and the earth are in the centre of interest and to a large extent dominate the theological debate. The rise of modern aggressive atheism, the scientific research on the historic Jesus, the growing questions about man and human society as well as the threatening ecological crisis on earth, provide new discourses of unparalleled magnitude. The author provides a broad summary of these discourses, with criticism where necessary, and concludes with some indicators of his view what can be called ‘good theology’.

    Full Text Available In die Grieks-Romeinse era het mediese behandeling kenmerkend uit drie elemente bestaan, naamlik regimen (dieet en gesonde leefwyse, geneesmiddels en chirurgie – laasgenoemde alleen toegepas indien regimen en geneesmiddels onsuksesvol was. Bewyse van primitiewe chirurgie dateer terug na die Bronstydperk, en in Homerus se eposse is heelwat vermelding van die chirurgiese hantering van oorlogswonde, met tussenkoms van die gode. Met die koms van empiriese geneeskunde in die 5de eeu v.C. het chirurgie in die Hippokratiese Corpus prominent gefigureer met beduidende bydraes in veral die ortopediese veld en hoofbeserings. Uitbouing van anatomiese en fisiologiese kennis, gebaseer op disseksie van menslike kadawers in Alexandrië vanaf die laat 4de eeu v.C., het chirurgie ’n hupstoot gegee. Teen die Romeinse era vanaf die 2de eeu v.C. het snykundetegnieke (en -instrumente beduidend verbeter, maar is steeds oorwegend deur Griekse geneeshere beoefen. Van geneeshere is steeds verwag om al drie bovermelde terapeutiese modaliteite te bemeester, maar chirurgie het meer aansien verwerf en daar is al meer in onderafdelings van chirurgie soos oogheelkunde, vrouesiektes en verloskunde, blaaskwale en mond- en keelsnykunde gespesialiseer. Militêre geneeskunde was in die Romeinse Ryk ’n belangrike aktiwiteit, en het veral traumachirurgie uitgebou. Betreding van die buik- en toraksholtes was nie meer noodwendig fataal nie, en veeartsenykunde het tot stand gekom. Die eerste beduidende chirurgiehandboek ná die Hippokratiese Corpus is in die 1ste eeu n.C. deur Celsus opgestel. Vanaf die 3de eeu het die chirurgieberoep min vordering gemaak, die beroepstaal het mettertyd van Grieks na Latyn verander en kundigheid is later veral deur Islam-geneeshere na die Middeleeue en later oorgedra.

    Full Text Available Onlinesupervision im Hinblick auf Fallbesprechungen aus der Onlineberatung ist sinnvoll, zumal die auftauchenden Fragestellungen, welche häufig nur im Kontext des Mediums nachvollziehbar sind, durch das gleiche Medium besprochen werden, in dem sie auch entstanden sind. Angefangen von der schriftkommunzierten Falldarstellung, dem reduzierten Gefühlsaudruck bis hin zu den Interventionen bietet dieses Medium vielfältige und onlinespezifische Arbeitsmethoden. Allerdings ist es – neben den beschriebenen Grenzen – auch wichtig, immer wieder ein Gegengewicht zur "virtuellen Welt" herzustellen und wieder "Bodenhaftung" zu spüren, was hauptsächlich in der face-to-face-Beratungssituation möglich ist. Somit stellt die Onlinesupervision eine eigenständige und hilfreiche Möglichkeit dar, die eigene Arbeit kontextnah zu betrachten und zu hinterfragen, sofern sie zielgerichtet und eventuell ergänzend zur Live-Supervision eingesetzt wird.

    Full Text Available Learning theory basis of andragogy. A cursory glance at andragogy creates the impression that humanistic learning theory plays an all encompassing role in the learner centered approach andragogy espouses. A closer look, however, reveals that Knowles (1973, after having made an intensive study of learning theory, created an extensive framework within which human resource development can take place. The fact that Knowles attracted critique from different areas, led to a need to ascertain the role different learning theories, if any, played in the emergence of andragogy. Having looked at the assumptions displayed by the andragogical approach, as well as a comparison of different learning theories and their connection with andragogy, it became clear that andragogy contains elements of various learning theories in an adapted way. These adaptations resulted in an approach to adult education in which learners are given the opportunity to be part of the learning process in such a way that they themselves contribute to the development which takes place. Opsomming Met 'n eerste oogopslag wil dit voorkom asof humanistiese leerteorie 'n oorheersende rol in die leerdergesentreerde benadering van andragogie speel. By nadere ondersoek blyk dit egter dat Knowles (1973, na 'n deeglike studie van verskillende leerteoretiese beginsels, 'n omvangryke raamwerk geskep het waarbinne, aan die hand van verskeie aangepaste leerteoretiese beginsels, menslike hulpbronontwikkeling kan plaasvind. As gevolg van die feit dat Knowles vanuit verskillende oorde kritiek op die lyf geloop het, is besluit om die rol wat verskillende leerteorieë in andragogie speel, te bestudeer. Dit blyk dat andragogie nie net elemente van verskillende leerteorieë bevat nie, maar dat toepaslike aspekte van die teoriee wat ondersoek is, benut en aangepas is om 'n geintegreerde benadering te bewerkstellig waarin veral volwassene-leerders by leergeleenthede en hulle selfontwikkeling betrek word.

    Full Text Available In recent years, dealing with a lot of data originating from social media sites and mobile communications among data from business environments and institutions, lead to the definition of a new concept, known as Big Data. The economic impact of the sheer amount of data produced in a last two years has increased rapidly. It is necessary to aggregate all types of data (structured and unstructured in order to improve current transactions, to develop new business models, to provide a real image of the supply and demand and thereby, generate market advantages. So, the companies that turn to Big Data have a competitive advantage over other firms. Looking from the perspective of IT organizations, they must accommodate the storage and processing Big Data, and provide analysis tools that are easily integrated into business processes. This paper aims to discuss aspects regarding the Big Data concept, the principles to build, organize and analyse huge datasets in the business environment, offering a three-layer architecture, based on actual software solutions. Also, the article refers to the graphical tools for exploring and representing unstructured data, Gephi and NodeXL.

    Full Text Available Die vyand is mislei en verrasDie vraag is dikwels gestel waarom die Italiaanse lugmag geen rol gespeel het om die aanmars teen Suid-Abessinië en die aanvalle op die voorposte te stuit nie. Behalwe die feit dat die Italianers nie onmiddellik van die aanmars geweet het nie, het die Hertog van Aosta in 'n rapport aan die Italiaanse weermagshoofkwartier in Rome te kenne gegee dat die lugmag nie kon optree nie weens 'n tekort aan vliegtuie. In die lig van die sterk lugmagbasisse na aan die buiteposte, by Neghelli en Yavello, is hierdie rede myns insiens nie meor as 'n minder geloofwaardige verskoning nie. Die Suid-Afrikaanse lugmag, wat boonop in 'n vyandelike lugruim moes beweeg, het vyandelike basisse getakel met slegs enkele vliegtuie - soms met net een. Die waarheid is eerder dat die Italiaanse inligtingsdiens op 'n verkeerde voet gevang is en dat die beskikbare lugmag en landmagte onvoorbereid en ongemotiveerd was om die koppige Springbokaanmars te stu it. 1 SA Divisie het hulle mislei om te glo alles is veilig en daarna drie buiteposte binne twee dae platgeloop.

    BigBOSS is a Stage IV ground-based dark energy experiment to study baryon acoustic oscillations (BAO) and the growth of structure with a wide-area galaxy and quasar redshift survey over 14,000 square degrees. It has been conditionally accepted by NOAO in response to a call for major new instrumentation and a high-impact science program for the 4-m Mayall telescope at Kitt Peak. The BigBOSS instrument is a robotically-actuated, fiber-fed spectrograph capable of taking 5000 simultaneous spectra over a wavelength range from 340 nm to 1060 nm, with a resolution R = {lambda}/{Delta}{lambda} = 3000-4800. Using data from imaging surveys that are already underway, spectroscopic targets are selected that trace the underlying dark matter distribution. In particular, targets include luminous red galaxies (LRGs) up to z = 1.0, extending the BOSS LRG survey in both redshift and survey area. To probe the universe out to even higher redshift, BigBOSS will target bright [OII] emission line galaxies (ELGs) up to z = 1.7. In total, 20 million galaxy redshifts are obtained to measure the BAO feature, trace the matter power spectrum at smaller scales, and detect redshift space distortions. BigBOSS will provide additional constraints on early dark energy and on the curvature of the universe by measuring the Ly-alpha forest in the spectra of over 600,000 2.2 < z < 3.5 quasars. BigBOSS galaxy BAO measurements combined with an analysis of the broadband power, including the Ly-alpha forest in BigBOSS quasar spectra, achieves a FOM of 395 with Planck plus Stage III priors. This FOM is based on conservative assumptions for the analysis of broad band power (k{sub max} = 0.15), and could grow to over 600 if current work allows us to push the analysis to higher wave numbers (k{sub max} = 0.3). BigBOSS will also place constraints on theories of modified gravity and inflation, and will measure the sum of neutrino masses to 0.024 eV accuracy.

    Future advances in the auditory systems are difficult to predict, and only educated guesses are possible. It is expected that innovative technologies in the field of neuroscience will be applied to the auditory system. Optogenetics, Brainbow, and CLARITY will improve our knowledge of the working of neural auditory networks and the relationship between sound and language, providing a dynamic picture of the brain in action. CLARITY makes brain tissue transparent and offers a three-dimensional view of neural networks, which, combined with genetically labeling neurons with multiple, distinct colors (Optogenetics), will provide detailed information of the complex brain system. Molecular functional magnetic resonance imaging (MRI) will allow the study of neurotransmitters detectable by MRI and their function in the auditory pathways. The Human Connectome project will study the patterns of distributed brain activity that underlie virtually all aspects of cognition and behavior and determine if abnormalities in the distributed patterns of activity may result in hearing and behavior disorders. Similarly, the programs of Big Brain and ENIGMA will improve our understanding of auditory disorders. New stem-cell therapy and gene therapies therapy may bring about a partial restoration of hearing for impaired patients by inducing regeneration of cochlear hair cells. PMID:25726297

    Full Text Available The end of the world: The challenge of modern science to traditional eschatology. In biblical times the ‘Word of God’ indicated God’s creative and redemptive response to changing human predicaments and depravations. Redemptive events became traditions that were applied to new situations. Many biblical future expectations lost their relevance and plausibility already within canonical history. Modern science has rendered a literal interpretation of the most recent and radical biblical future expectations – resurrection and a ‘new heaven and earth’ – problematic. Apocalyptic deliberately employed enigmatic symbols and metaphors to indicate God’s miraculous intervention to change an evil world into a new and authentic reality. This motif can be reconceptualised as God’s vision for the comprehensive optimal well-being of humanity within the well-being of creation as a whole, which translates into God’s concern for any deficiency in well-being in any dimension of life. The emergence of the notion of resurrection to face judgement was rooted in concern about God’s justice (theodicy rather than the longing for never-ending life. The resurrection of Jesus was deemed God’s affirmation of his messianic authority to proclaim and enact God’s redeeming love, thus its validity for all times and places – which opened up participation in the new life of Christ in fellowship with God for all people.
