    The author describes the retrospective data acquisition and evaluation on the characterization and prognosis for 776 patients (average age 40:1 years) with differentiated thyroid carcinomas in the Klinik und Poliklinik fuer Nuklearmedizin der Universitaet zu Koeln in the period from 1990 to 2005. The methodology includes patient-relevant data, examination data, imaging techniques and biochemical tests. Clinically important differences were found for papillary and follicular thyroid carcinoma. Further differences concern the localization of metastases. The author discusses the prognostic significance of the primary tumor radius in comparison with the so-called TNM classification for papillary and follicular thyroid carcinomas. It is concluded that the new version of the TNM classification offers only slight advantages with respect to the former version. It was also shown that the primary tumor size is adequate for prognostic estimations.

    Skelettszintigraphie ein Indikationsspektrum bewahrt, in dem sie - gegebenenfalls auch additiv zur MRT - eingesetzt werden kann. Wesentliche Indikationen sind die szintigraphische Ganzkoerpertechnik, die Bestimmung des relativen Frakturalters, unklare Schmerzsituationen, periartikulaere Verkalkungen und trophische Stoerungen (Algodystrophie) sowie die Bestandsaufnahme des Schadensausmasses nach Polytrauma. Steht MRT nicht zur Verfuegung, deckt die Skelettszintigraphie auch diese Indikationen ab: Nachweis bzw. Ausschluss von Ischaemien und Nekrosen des Knochens, Stress- und Insuffizienzfrakturen, Differenzierung von Weichteil- vs. Knochenverletzungen und die so genannten ''bone bruises''. Der gleiche Katalog gilt auch, wenn technische Probleme im MR vorliegen (Schrittmacherpatient, Narkoseprobleme bei Klaustrophobiepatienten, Adipositas per magna sowie Metallartefakte). Voraussetzung fuer einen effizienten Einsatz der Skelettszintigraphie in der Traumatologie sind allerdings optimierte Untersuchungstechniken (SPECT im Bereich des Koerperstammes, multiplanare Darstellung im Extremitaetenbreich), gute anatomische Kenntnisse in Verbindung mit einer exakten Anamnese und die synoptische Interpretation der funktionellen skelettszintigraphischen Befunde zusammen mit den morphologischen Informationen von Sonographie und Roentgen und gegebenenfalls MRT.

    Full Text Available [english] Problem-based learning (PBL is an established and efficient approach to sustainable teaching. Here, we describe translation of PBL into the virtual classroom thereby offering novel teaching aspects in the field of Nuclear Medicine. Our teaching approach is implemented on a "moodle" platform and consists of 2 modules: complementary seminar teaching materials and a virtual PBL-classroom, which can be attended via Skype.Over the course of 4 semesters 539 students have accessed our teaching platform. 21 students have participated in the PBL seminar (module 2. After resolving some minor technical difficulties our virtual seminars have evolved into a forum of intense studies, whereby the participating students have learned to become more independent along the workup of the teaching cases. This was reflected in the results of the intra-group presentations and discussions.Quantitative and qualitative evaluation of our moodle-based PBL platform indicates an increasing level of acceptance and enthusiasm by the students. This has initiated discussions about opening our PBL concept to a wider audience within the university and beyond the Nuclear Medicine specialty.[german] Problem-orientiertes Lernen (POL ist eine etablierte und effiziente Methode zur nachhaltigen Lehre. In dem beschriebenen Projekt wurde der Versuch unternommen, das POL-Konzept in den virtuellen Raum zu übertragen, um die Lehre in der Nuklearmedizin zu ergänzen und motivierte Studierende für das Fach zu interessieren. Das Lehrprojekt auf Basis der Lehrplattform „moodle“ besteht aus zwei Teilen: Seminar-begleitende Seiten zur Nachbereitung der Vorlesung und ein virtueller POL-Bereich, in dem über eine Internet-basierte Telefonkonferenz POL-Fälle bearbeitet werden können. Insgesamt haben in vier Semestern 539 Studierende auf die Lehrplattform zugegriffen, von denen 21 an einem POL-Seminar teilgenommen haben. Nach anfänglichen – teils technischen – Schwierigkeiten

    Designed for an advanced undergraduate- or graduate-level course, Abstract Algebra provides an example-oriented, less heavily symbolic approach to abstract algebra. The text emphasizes specifics such as basic number theory, polynomials, finite fields, as well as linear and multilinear algebra. This classroom-tested, how-to manual takes a more narrative approach than the stiff formalism of many other textbooks, presenting coherent storylines to convey crucial ideas in a student-friendly, accessible manner. An unusual feature of the text is the systematic characterization of objects by universal

    A tank made of stainless steel type X2CrNiMo17-12-2 for intermediate storage of salt brine for cheese production revealed significant pitting corrosion effects shortly after commissioning although comparable units have shown positive long-term behaviour. By means of electrochemical laboratory tests it could be demonstrated that the observed pitting corrosion was caused by the use of an oxidizing agent for desinfection purposes. (Abstract Copyright [2003], Wiley Periodicals, Inc.) [German] An einem Tankbehaelter aus dem Werkstoff X2CrNiMo17-12-2, der zur Zwischenlagerung von Salzlake fuer die Kaeseherstellung dient, wurden trotz langjaehriger positiver Erfahrungen an vergleichbaren Anlagen bereits kurze Zeit nach der Inbetriebnahme Lochkorrosionserscheinungen festgestellt. Durch entsprechende elektrochemische Laboruntersuchungen konnte gezeigt werden, dass die vorgefundene Lochkorrosion durch den Einsatz eines Oxidationsmittels zu Desinfektionszwecken verursacht wurde.

Hans Richter’s famous piece Rhythmus 21 is considered to be the first abstract film in the experimental tradition. The Webdriver Torso YouTube channel is composed of hundreds of thousands of machine-generated test patterns designed to check frequency signals on YouTube. This article discusses geometric abstraction vis-à-vis new vision, conceptual art and algorithmic art. It argues that the Webdriver Torso is an artistic marvel indicative of a form we call mathematical abstraction, which is art performed by computers and, quite possibly, for computers.

    The pollution of air by nitrogen dioxide (NO{sub 2}) in cities is one of the central challenges of air pollution in Germany, in addition to the pollution of particulate matter (PM10). In cooperation with the British non-governmental organization ClientEarth, the German Environmental Aid (DUH) filed a lawsuit in November 2015 for exceeding air quality limits for NO{sub 2}. The cities of Stuttgart, Frankfurt, Duesseldorf, Essen, Gelsenkirchen, Aachen, Cologne and Bonn are affected. Here, citizens are constantly exposed to high air pollution. Because of the excess of the NO{sub 2} limits at all traffic-related measuring stations in Berlin, the DUH initiated legal steps and filed a lawsuit too in June 2016. With the lawsuits, DUH wants to promote the implementation of measures to reduce NO{sub 2} in Germany. [German] Die Belastung der Luft durch Stickstoffdioxid (NO{sub 2}) in Staedten ist neben der Belastung durch Feinstaub (PM10) eine der zentralen Herausforderungen der Luftreinhaltung in Deutschland. In Zusammenarbeit mit der britischen Nichtregierungsorganisation ClientEarth legte die Deutsche Umwelthilfe (DUH) im November 2015 Klage wegen Ueberschreitung der Luftqualitaetsgrenzwerte fuer NO{sub 2}ein. Betroffen sind die Staedte Stuttgart, Frankfurt, Duesseldorf, Essen, Gelsenkirchen, Aachen, Koeln und Bonn. Hier sind Buergerinnen und Buerger anhaltend zu hoher Luftverschmutzung ausgesetzt. Wegen Ueberschreitung der NO{sub 2}-Grenzwerte an allen verkehrsnahen Messstationen in Berlin hat die DUH im Juni 2016 auch hier rechtliche Schritte eingeleitet und Klage eingereicht. Mit den Klagen will die DUH die Umsetzung von Massnahmen zur NO{sub 2}-Reduktion in Deutschland voranbringen.

    Advanced simulation tools were used in developing the climate design for the roof covering the taller of the two blocks at Moscow's Federation Tower. The all-glass roof space at a height of 365 m is designed to accommodate the finest and most exclusive hotel areas. Several restaurants, bars and lounges and a Sky Dance Club will offer entertainment and fabulous views across the whole city. Simulations were used to develop and verify a design that ensures thermal comfort taking into account architectural, climate and utilisation requirements. The structure and the building services were simulated based on a 3D model, and simulations were carried out for summer and winter scenarios. This paper describes the design process including load calculations and the development and assessment of the climate design by means of simulation. (Abstract Copyright [2008], Wiley Periodicals, Inc.) [German] In der Entwicklung des Klimakonzeptes der Turmkappe Ost des Federation Towers in Moskau wurden modernste Simulationswerkzeuge eingesetzt. Die vollstaendig glaeserne Turmkappe in 365 m Hoehe soll Raum fuer einen der schoensten und exklusivsten Bereiche des Hotels geben. Diverse Restaurants, Bars und Lounges sowie ein Sky Dance Club sollen einmal zum Verweilen und zur naechtlichen Vergnuegung einladen und dabei stets einen traumhaften Blick ueber die gesamte Stadt ermoeglichen. Mit Hilfe der Simulation wurde fuer die Turmkappe ein Klimakonzept entwickelt und ueberprueft, das die thermische Behaglichkeit unter Beruecksichtigung von Architektur, Klima und Nutzung gewaehrleistet. Dazu wurde die Architektur inklusive der Klimatechnik in einem 3D-Modell abgebildet und fuer den Sommer- und Winterfall berechnet. Der vorliegende Beitrag vollzieht den Planungsablauf von der Lastberechnung bis hin zur Erstellung und Bewertung des Klimakonzeptes in der Simulation.

    Within a joint project of the steel and automotive industry 17 steel sheet materials for automotive engineering in various delivery and forming conditions at temperatures of -40 C, 22 C and 100 C were investigated. In the course of 37 test series strain controlled fatigue curves to crack initiation and stress-strain-curves under monotonic and cyclic loading were determined. All experimental data, hysteresis loops and determined cyclic properties are available in a database. A correlation between the mechanical properties from tensile tests and the properties from strain controlled cyclic experiments seems to be possible.

    Doctors today already frequently rely on positron emission tomography - PET for short - in cancer diagnostics. However, in order to use this method for other diseases, too, they need suitable tracer substances containing radioactive fluorine-18 - a challenge for Tobias Ritter and his team at the Max Planck Institut fuer Kohlenforschung in Muelheim an der Ruhr. The chemists are searching for ways to label diverse molecules with fluorine-18 and thus expand the range of possibilities for medical specialists.

  2. Metacognition and abstract reasoning.

    The nature of people's meta-representations of deductive reasoning is critical to understanding how people control their own reasoning processes. We conducted two studies to examine whether people have a metacognitive representation of abstract validity and whether familiarity alone acts as a separate metacognitive cue. In Study 1, participants were asked to make a series of (1) abstract conditional inferences, (2) concrete conditional inferences with premises having many potential alternative antecedents and thus specifically conducive to the production of responses consistent with conditional logic, or (3) concrete problems with premises having relatively few potential alternative antecedents. Participants gave confidence ratings after each inference. Results show that confidence ratings were positively correlated with logical performance on abstract problems and concrete problems with many potential alternatives, but not with concrete problems with content less conducive to normative responses. Confidence ratings were higher with few alternatives than for abstract content. Study 2 used a generation of contrary-to-fact alternatives task to improve levels of abstract logical performance. The resulting increase in logical performance was mirrored by increases in mean confidence ratings. Results provide evidence for a metacognitive representation based on logical validity, and show that familiarity acts as a separate metacognitive cue.

    1998-06-01

    Integral energy concepts for housing estates require an early cooperation between architects, planners, and specialist engineers on the basis of a holistic planning approach. This is how future-oriented, sustainable concepts evolve which do justice to the multifarious requirements on the integral energy system of a housing estate. The present paper elucidates different approaches to optimising the energy efficiency of buildings such as the implementation of low-energy house concepts, building site and architectural planning, and detailed planning of heat insulation concepts, ventilation and air tightness concepts, and adapted heating systems. The solarisation of development plans has an influence on the arrangement of buildings, which are now planned to give the greatest possible passive and active solar energy gains. The authors also describe solar-assisted district heating systems for housing estates. [Deutsch] Integrale Energiekonzepte fuer Wohnsiedlungen erfordern die fruehe Zusammenarbeit von Architekten, Planern und Fachingenieuren im Rahmen einer ganzheitlichen Planung. So entstehen zukunftsweisende und tragfaehige Konzepte, die den vielschichtigen Anforderungen des Gesamtenergiesystems ``Wohnsiedlung`` gerecht werden. Im Folgenden wird die energetische Optimierung von Gebaeuden wie die Umsetzung von Niedrigenergiehaus-Konzepten, Standort und Gebaeudeplanung sowie Detailplanung in Bezug auf das Waermedaemmkonzept, Lueftungs-/Dichtheitskonzept und auf angepasste Waermeversorgungssysteme erl autert.

A secondary purpose of this model report is to provide information for criticality studies related to seismic hazards. The seismic hazards addressed herein are vibratory ground motion, fault displacement, and rockfall due to ground motion. The EBS components are the drip shield, the waste package, and the fuel cladding. The requirements for development of the abstractions and the associated algorithms for the seismic scenario class are defined in ''Technical Work Plan For: Regulatory Integration Modeling of Drift Degradation, Waste Package and Drip Shield Vibratory Motion and Seismic Consequences'' (BSC 2004 [DIRS 171520]). The development of these abstractions will provide a more complete representation of flow into and transport from the EBS under disruptive events. The results from this development will also address portions of integrated subissue ENG2, Mechanical Disruption of Engineered Barriers, including the acceptance criteria for this subissue defined in Section 2.2.1.3.2.3 of the ''Yucca Mountain Review Plan, Final Report'' (NRC 2003 [DIRS 163274])

    Lewin, Philip

    Piaget's theory of reflective abstraction can supplement cognitive science models of representation by specifying both the act of construction and the component steps through which knowers pass as they acquire knowledge. But, while approaches suggested by cognitive science supplement Piaget by awakening researchers to the role of auxiliary factors…

  7. EBS Radionuclide Transport Abstraction

    Schreiner, R.

    2001-01-01

    The purpose of this work is to develop the Engineered Barrier System (EBS) radionuclide transport abstraction model, as directed by a written development plan (CRWMS M and O 1999a). This abstraction is the conceptual model that will be used to determine the rate of release of radionuclides from the EBS to the unsaturated zone (UZ) in the total system performance assessment-license application (TSPA-LA). In particular, this model will be used to quantify the time-dependent radionuclide releases from a failed waste package (WP) and their subsequent transport through the EBS to the emplacement drift wall/UZ interface. The development of this conceptual model will allow Performance Assessment Operations (PAO) and its Engineered Barrier Performance Department to provide a more detailed and complete EBS flow and transport abstraction. The results from this conceptual model will allow PA0 to address portions of the key technical issues (KTIs) presented in three NRC Issue Resolution Status Reports (IRSRs): (1) the Evolution of the Near-Field Environment (ENFE), Revision 2 (NRC 1999a), (2) the Container Life and Source Term (CLST), Revision 2 (NRC 1999b), and (3) the Thermal Effects on Flow (TEF), Revision 1 (NRC 1998). The conceptual model for flow and transport in the EBS will be referred to as the ''EBS RT Abstraction'' in this analysis/modeling report (AMR). The scope of this abstraction and report is limited to flow and transport processes. More specifically, this AMR does not discuss elements of the TSPA-SR and TSPA-LA that relate to the EBS but are discussed in other AMRs. These elements include corrosion processes, radionuclide solubility limits, waste form dissolution rates and concentrations of colloidal particles that are generally represented as boundary conditions or input parameters for the EBS RT Abstraction. In effect, this AMR provides the algorithms for transporting radionuclides using the flow geometry and radionuclide concentrations determined by other

    The purpose of this report is to develop and analyze the engineered barrier system (EBS) radionuclide transport abstraction model, consistent with Level I and Level II model validation, as identified in Technical Work Plan for: Near-Field Environment and Transport: Engineered Barrier System: Radionuclide Transport Abstraction Model Report Integration (BSC 2005 [DIRS 173617]). The EBS radionuclide transport abstraction (or EBS RT Abstraction) is the conceptual model used in the total system performance assessment (TSPA) to determine the rate of radionuclide releases from the EBS to the unsaturated zone (UZ). The EBS RT Abstraction conceptual model consists of two main components: a flow model and a transport model. Both models are developed mathematically from first principles in order to show explicitly what assumptions, simplifications, and approximations are incorporated into the models used in the TSPA. The flow model defines the pathways for water flow in the EBS and specifies how the flow rate is computed in each pathway. Input to this model includes the seepage flux into a drift. The seepage flux is potentially split by the drip shield, with some (or all) of the flux being diverted by the drip shield and some passing through breaches in the drip shield that might result from corrosion or seismic damage. The flux through drip shield breaches is potentially split by the waste package, with some (or all) of the flux being diverted by the waste package and some passing through waste package breaches that might result from corrosion or seismic damage. Neither the drip shield nor the waste package survives an igneous intrusion, so the flux splitting submodel is not used in the igneous scenario class. The flow model is validated in an independent model validation technical review. The drip shield and waste package flux splitting algorithms are developed and validated using experimental data. The transport model considers advective transport and diffusive transport

      The anniversary of the International Journal of Lifelong Education takes place in the middle of a conceptual landslide from lifelong education to lifelong learning. Contemporary discourses of lifelong learning etc are however abstractions behind which new functions and agendas for adult education...... are set. The ideological discourse of recent policies seems to neglect the fact that history and resources for lifelong learning are different across Europe, and also neglects the multiplicity of adult learners. Instead of refusing the new agendas, however, adult education research should try to dissolve...... learning.

    Full Text Available Dataflow networks have application in various forms of stream processing, for example for parallel processing of multimedia data. The description of dataflow graphs, including their firing behavior, is typically non-compositional and not amenable to separate compilation. This article considers a dataflow language with a type and effect system that captures the firing behavior of actors. This system allows definitions to abstract over actor firing rates, supporting the definition and safe composition of actor definitions where firing rates are not instantiated until a dataflow graph is launched.

  3. ABSTRACTION OF DRIFT SEEPAGE

    International Nuclear Information System (INIS)

    Wilson, Michael L.

    2001-01-01

    Drift seepage refers to flow of liquid water into repository emplacement drifts, where it can potentially contribute to degradation of the engineered systems and release and transport of radionuclides within the drifts. Because of these important effects, seepage into emplacement drifts is listed as a ''principal factor for the postclosure safety case'' in the screening criteria for grading of data in Attachment 1 of AP-3.15Q, Rev. 2, ''Managing Technical Product Inputs''. Abstraction refers to distillation of the essential components of a process model into a form suitable for use in total-system performance assessment (TSPA). Thus, the purpose of this analysis/model is to put the information generated by the seepage process modeling in a form appropriate for use in the TSPA for the Site Recommendation. This report also supports the Unsaturated-Zone Flow and Transport Process Model Report. The scope of the work is discussed below. This analysis/model is governed by the ''Technical Work Plan for Unsaturated Zone Flow and Transport Process Model Report'' (CRWMS MandO 2000a). Details of this activity are in Addendum A of the technical work plan. The original Work Direction and Planning Document is included as Attachment 7 of Addendum A. Note that the Work Direction and Planning Document contains tasks identified for both Performance Assessment Operations (PAO) and Natural Environment Program Operations (NEPO). Only the PAO tasks are documented here. The planning for the NEPO activities is now in Addendum D of the same technical work plan and the work is documented in a separate report (CRWMS MandO 2000b). The Project has been reorganized since the document was written. The responsible organizations in the new structure are the Performance Assessment Department and the Unsaturated Zone Department, respectively. The work plan for the seepage abstraction calls for determining an appropriate abstraction methodology, determining uncertainties in seepage, and providing

    Lifetime management, ageing management and integrity testing are part of technical rules and specifications. The contribution focuses on ageing management, for which different technical measures are required depending on the safety relevance of the components and systems involved. The procedure for ensuring adherence to the specified quality is outlined, and the required technical and organisational measures are explained. (orig.)

Ein wesentliches Element stellt dabei das Alterungsmanagement dar. Je nach sicherheitstechnischer Bedeutung der zu betrachtenden Komponenten und Systeme oder auch aus Gruenden der vorbeugenden Instandhaltung sind unterschiedliche technische Massnahmen erforderlich. Die Vorgehensweise zur Absicherung der im Betrieb geforderten Qualitaet wird aufgezeigt und die dabei erforderlichen technischen und organisatorischen Massnahmen werden erlaeutert. (orig.)

    The following parameters merit examination in determining the viability of process combinations: conceptual and technical soundness, environmental acceptability, energy balance, flexibility, costs, economic risk potential. The present contribution on this subject is not intended to take the place of or cover the scope of single-case studies. In practice, viability studies on process combinations have to deal with concrete plans involving precisely defined material flow balances, emissions, costs etc. The present paper therefore only presents the basic principles of this type of study. [Deutsch] Folgende Randbedingungen fuer sinnvolle Verfahrenskombinationen sind zu untersuchen: - konzeptionelle und technische Stimmigkeit, - Umweltvertraeglichkeit, - energetische Bilanz, - Flexibilitaet, - Kosten, - oekonomisches Risikopotential.

Im Rahmen einer echten Pruefung auf `Sinnhaftigkeit` einer Kombinationsloesung stehen sich ganz konkrete Planungen gegenueber, die wiederum mit definierten Stoffflussbilanzen, Emissionen, Kosten usw. verbunden sind.

  15. Exoplanets and Multiverses (Abstract)

    (Abstract only) To the ancients, the Earth was the Universe, of a size to be crossed by a god in a day, by boat or chariot, and by humans in a lifetime. Thus an exoplanet would have been a multiverse. The ideas gradually separated over centuries, with gradual acceptance of a sun-centered solar system, the stars as suns likely to have their own planets, other galaxies beyond the Milky Way, and so forth. And whenever the community divided between "just one' of anything versus "many," the "manies" have won. Discoveries beginning in 1991 and 1995 have gradually led to a battalion or two of planets orbiting other stars, very few like our own little family, and to moderately serious consideration of even larger numbers of other universes, again very few like our own. I'm betting, however, on habitable (though not necessarily inhabited) exoplanets to be found, and habitable (though again not necessarily inhabited) universes. Only the former will yield pretty pictures.

    The microscopic origin of unconventional superconductivity continues to attract the attention of the condensed matter community. Whereas rare-earth / actinide-based intermetallic and copper oxide-based high temperature superconductors are studied for more than twenty years, the iron-based superconductors have been in the focus of interest since their recent discovery. Inelastic neutron scattering experiments have been of particular importance for the understanding of the magnetic and superconducting properties of these compounds. With its 29 talks and 14 posters the workshop provided a forum for the 71 registered participants to review and discuss experimental achievements, recognize the observed synergy and differences as well as discuss theoretical efforts to identify the symmetry of the superconducting order parameter in addition to the coupling mechanisms of the Cooper pairs. The workshop covered different topics relevant for the study of unconventional superconductivity. Magnetization and lattice dynamics such as spin resonances, phonons, magnetic and other excitations as studied by spectroscopic methods were presented. Investigations of (doping, pressure and magnetic field dependent) phase diagrams, electronic states as well as vortex physics by the various diffraction techniques were also addressed. This document gathers only the abstracts of the papers. (authors)

  18. Automated Supernova Discovery (Abstract)

    (Abstract only) We are developing a system of robotic telescopes for automatic recognition of Supernovas as well as other transient events in collaboration with the Puckett Supernova Search Team. At the SAS2014 meeting, the discovery program, SNARE, was first described. Since then, it has been continuously improved to handle searches under a wide variety of atmospheric conditions. Currently, two telescopes are used to build a reference library while searching for PSN with a partial library. Since data is taken every night without clouds, we must deal with varying atmospheric and high background illumination from the moon. Software is configured to identify a PSN, reshoot for verification with options to change the run plan to acquire photometric or spectrographic data. The telescopes are 24-inch CDK24, with Alta U230 cameras, one in CA and one in NM. Images and run plans are sent between sites so the CA telescope can search while photometry is done in NM. Our goal is to find bright PSNs with magnitude 17.5 or less which is the limit of our planned spectroscopy. We present results from our first automated PSN discoveries and plans for PSN data acquisition.

    (Abstract only) The AAVSO is in the process of expanding its education, outreach and speakers bureau program. powerpoint presentations prepared for specific target audiences such as AAVSO members, educators, students, the general public, and Science Olympiad teams, coaches, event supervisors, and state directors will be available online for members to use. The presentations range from specific and general content relating to stellar evolution and variable stars to specific activities for a workshop environment. A presentation—even with a general topic—that works for high school students will not work for educators, Science Olympiad teams, or the general public. Each audience is unique and requires a different approach. The current environment necessitates presentations that are captivating for a younger generation that is embedded in a highly visual and sound-bite world of social media, twitter and U-Tube, and mobile devices. For educators, presentations and workshops for themselves and their students must support the Next Generation Science Standards (NGSS), the Common Core Content Standards, and the Science Technology, Engineering and Mathematics (STEM) initiative. Current best practices for developing relevant and engaging powerpoint presentations to deliver information to a variety of targeted audiences will be presented along with several examples.

    Wholesome living does not contradict energy saving provided that efficient space HVAC systems and low-emission construction materials are used. In view of the reduced controlled air change in passive buildings, emissions from interior materials and furniture should be taken into account as well. The IUG developed a catalogue of criteria of a 'low-allergy building'. The principles and rules governing the construction of a passive building for people suffering from allegies are presented. [German] Gesundes Wohnen und Energiesparen sind kein Widerspruch. Bei staendiger Zunahme innenraumbedingter Allergien sind insbesonders Anfordernisse an Baumaterialien und Raumluft-technische-Anlagen (RLT) zu stellen. Schon fuer die Planer ist es wichtig emissionsarme Baumaterialien einzusetzen. Aufgrund der kontrolliert reduzierten Luftwechselraten sollten ausserdem Emissionen aus Einrichtungsmaterialien wie Bodenbelaege und Moebel mit in die Beurteilung von Passivhaeusern einbezogen werden. Darueber hinaus koennen konstruktionsbedingte Massnahmen einen Schutz fuer zu Allergien neigenden Menschen bedeuten. Das IUG hat einen Pruef- und Kriterienkatalog fuer ein 'Allergiker-gerechtes Oeko-Haus - AL - LOeKH' entwickelt, mit welchem Gebaeude und Anlagen sowohl auf ihre oekologischen Kriterien als auch auf ihre Eignung fuer Allergiker geplant, geprueft und beurteilt werden und bei positiver Bewertung ein entsprechendes IUG-Label vergeben werden kann. In dem vorliegenden Beitrag sollten die Prinzipien und Regeln zur Errichtung und Einrichtung eines Passivhauses dargestellt werden, die die besonderen Anfordernisse fuer Allergiker (Atopiker) mit einschliessen.

    Preservation of agricultural soil is one of the key issues of sustainability policy. Composting and power generation must be weight against each other. While one user may be more interested in organic fertilizer, e.g. for market gardening, others may opt for power generation from biomass under the aspects of self-sufficiency and air pollution abatement. (orig.) [German] Im Sinne des Ressourcenschutzes sind die Minimierung des Verbrauchs von Rohstoffen sowie die Foerderung einer oekologisch sinnvollen und nachhaltigen Kreislaufwirtschaft und damit auch die Kompostverwertung zu foerdern. Fuer eine an den Prinzipien der Nachhaltigkeit orientierten Politik ist die langfristige Sicherung der Leistungs- und Funktionsfaehigkeit landwirtschaftlich genutzter Boeden fuer eine nachhaltige Ertragsfaehigkeit ein wichtiger Gesichtspunkt. Den landwirtschaftlichen Boeden kommt dabei eine besondere Bedeutung fuer die Produktion gesunder Lebensmittel zu. Abgleich Energienutzung, Kompostnutzung: Im Rahmen einer Einzelfallbetrachtung muss fuer jedes Unternehmen und fuer jeden Betrieb entschieden werden, welcher Weg der Verwertung von Bioabfaellen nachhaltig tragbar ist. So kann in dem einen Betrieb die Anreicherung des Bodens mit organischer Substanz, z.B. im Rahmen der Gemueseproduktion, im Vordergrund stehen, waehrend ein anderer Betrieb durch die energetische Nutzung von Biomasse einen Beitrag zur Eigenenergieversorgung und zum Klimaschutz leisten will.(orig)

  2. Abstraction of Drift Seepage

    2004-11-01

    This model report documents the abstraction of drift seepage, conducted to provide seepage-relevant parameters and their probability distributions for use in Total System Performance Assessment for License Application (TSPA-LA). Drift seepage refers to the flow of liquid water into waste emplacement drifts. Water that seeps into drifts may contact waste packages and potentially mobilize radionuclides, and may result in advective transport of radionuclides through breached waste packages [''Risk Information to Support Prioritization of Performance Assessment Models'' (BSC 2003 [DIRS 168796], Section 3.3.2)]. The unsaturated rock layers overlying and hosting the repository form a natural barrier that reduces the amount of water entering emplacement drifts by natural subsurface processes. For example, drift seepage is limited by the capillary barrier forming at the drift crown, which decreases or even eliminates water flow from the unsaturated fractured rock into the drift. During the first few hundred years after waste emplacement, when above-boiling rock temperatures will develop as a result of heat generated by the decay of the radioactive waste, vaporization of percolation water is an additional factor limiting seepage. Estimating the effectiveness of these natural barrier capabilities and predicting the amount of seepage into drifts is an important aspect of assessing the performance of the repository. The TSPA-LA therefore includes a seepage component that calculates the amount of seepage into drifts [''Total System Performance Assessment (TSPA) Model/Analysis for the License Application'' (BSC 2004 [DIRS 168504], Section 6.3.3.1)]. The TSPA-LA calculation is performed with a probabilistic approach that accounts for the spatial and temporal variability and inherent uncertainty of seepage-relevant properties and processes. Results are used for subsequent TSPA-LA components that may handle, for example, waste package

    A central question of today's political debates is: Which means are there for ensuring a long-term and sustainable energy supply? Here, strategies for covering tomorrow's energy supply assign renewable energies a decisive role. In face of constantly rising prices for fossil fuels like carbon, oil and gas or the still open question concerning the removal of atomic waste, these discussions are eminently urgent. In order to confront climatic change, renewable energies are needed, so that also in the future a longterm and sustainable energy supply is secured. Sustainable energy supply is the context for the project Solarsupport, which has been supported by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (FKZ 0327613). The project has been coordinated by the Institute for Environmental Questions (''Unabhaengige Institut fuer Umweltfragen e.V.'' - UFU) and conducted in cooperation with the Institute for Future Studies and Technology Assessment (''Institut fuer Zukunfststudien und Technologiebewertung gGmbH'' - IZT) and the German Society for Solar Energy, Regional Association Berlin-Brandenburg (Deutsche Gesellschaft fuer Sonnenenergie Regionalverband Berlin-Brandenburg e.V. - DGS). Particularly, the project is concerned with the pedagogical use of solar energy at school. Despite the relatively high number of solar plants at schools, only a few use their plants for pedagogical means. The project Solarsupport surveyed schools with solar plants. As the main reason for the insufficient pedagogical use of solar plants the interviewed teachers named the la ck of a pedagogical concept and their colleagues' disinterest, two factors which are able to reinforce one another. Moreover, it became clear that because of their insufficient technical equipment (no displays, no means for evaluating the plants' output, no connection with the school computers and internet) a high number of the

    The knowledge of employees of a company is the basis of all actions and decisions in the company and all existing (core) competences, which flow into products and services. Existing advantages in knowledge can be converted into competitive advantages by forward looking knowledge management. In addition there is an opportunity for increases in efficiency, creativity and quality. Locally different but often comparable boundary conditions, which are associated with similar problems, solutions, decisions and actions, prevail in the individual mines worldwide. Hence, knowledge management in international mining companies or joint ventures can contribute to the availability and use of knowledge relevant to value creation without delay in all company divisions. (orig.) [German] Das Wissen der Beschaeftigten ist die Grundlage aller im Unternehmen getaetigten Handlungen und Entscheidungen und aller (Kern-)Kompetenzen, die in Produkte und Dienstleistungen einfliessen. Durch ein zukunftsorientiertes Wissensmanagement lassen sich vorhandene Wissensvorspruenge in Wettbewerbsvorteile umwandeln. Es bietet zudem die Chance fuer Effizienz-, Kreativitaets- und Qualitaetssteigerungen. Im Bergbau herrschen weltweit in den einzelnen Bergwerken zwar lokal unterschiedliche, aber oftmals doch vergleichbare Rahmenbedingungen vor, die mit aehnlichen Problemen, Loesungen, Entscheidungen und Handlungen verbunden sind. Deshalb kann Wissensmanagement in international agierenden Bergbauunternehmen oder Kooperationen dazu beitragen, dass wertschoepfungsrelevantes Wissen ohne Zeitverzug in allen Unternehmensbereichen zur Verfuegung steht und genutzt wird.

    Full Text Available One key issue for theories of cognition is how abstract concepts, such as freedom, are represented. According to the WAT (Words As social Tools proposal, abstract concepts activate both sensorimotor and linguistic/social information, and their acquisition modality involves the linguistic experience more than the acquisition of concrete concepts. We report an experiment in which participants were presented with abstract and concrete definitions followed by concrete and abstract target-words. When the definition and the word matched, participants were required to press a key, either with the hand or with the mouth. Response times and accuracy were recorded. As predicted, we found that abstract definitions and abstract words yielded slower responses and more errors compared to concrete definitions and concrete words. More crucially, there was an interaction between the target-words and the effector used to respond (hand, mouth. While responses with the mouth were overall slower, the advantage of the hand over the mouth responses was more marked with concrete than with abstract concepts. The results are in keeping with grounded and embodied theories of cognition and support the WAT proposal, according to which abstract concepts evoke linguistic-social information, hence activate the mouth. The mechanisms underlying the mouth activation with abstract concepts (re-enactment of acquisition experience, or re-explanation of the word meaning, possibly through inner talk are discussed. To our knowledge this is the first behavioral study demonstrating with real words that the advantage of the hand over the mouth is more marked with concrete than with abstract concepts, likely because of the activation of linguistic information with abstract concepts.

    Longley, John R; Plotkin, Gordon

    2000-01-01

    We introduce the concept of logical full abstraction, generalising the usual equational notion. We consider the language PCF and two extensions with “parallel” operations. The main result is that, for standard interpretations, logical full abstraction is equivalent to equational full abstraction together with universality; the proof involves constructing enumeration operators. We also consider restrictions on logical complexity and on the level of types.

    1998-06-01

    It has been confirmed by practical project experience that integral energy concepts are an excellent basis for the construction of energy-efficient buildings. In the extreme case buildings can even be self-sufficient in their energy supply. Uniting the responsibility for the overall energy and technology concept in the hands of a single contractor can help reduce frictional losses between those involved in the planning as well costs. A good example of this is the use of a simulation calculation for the prescribed demonstration of proper heat insulation. The presented projects show that it is possible to construct ecologically answerable buildings at attractively low costs. The presented concepts appear particularly convincing from the viewpoint of long-term maintenance of value and user-specific advantages such as agreeable working conditions. [Deutsch] Die konkreten Projekterfahrungen bestaetigen, dass durch integrale Energiekonzepte sowohl im Verwaltungs- als auch im Wohnungsbau hervorragende Voraussetzungen fuer energiesparende Gebaeude geschaffen werden koennen. Im Extremfall kann sogar eine autarke Energieversorgung erreicht werden. Durch Zusammenfassung der Gesamtverantwortung fuer das Energie- und Technikkonzept in einer Hand koennen Reibungsverluste zwischen den Planungsbeteiligten reduziert und Kosten gesenkt werden. Ein Beispiel hierfuer ist die Verbindung des vorgeschriebenen Waermeschutznachweises mit einer fuer alle Beteiligten wesentlich aussagekraeftigeren Simulationsrechnung. Die vorgestellten Projekte zeigen, dass oekologisch sinnvolle Gebaeude auch zu oekonomisch attraktiven Kosten erstellt werden koennen, wobei insbesondere der Aspekt des langfristigen Werterhalts und die nutzerspezifischen Vorteile, z.B. durch angenehmere Arbeitsbedingungen, fuer die vorgestellten Konzepte spricht.

    Whether worldwide, on the European Continent, or at national level, natural gas is coming to the front everywhere. In Latin America or South-East Asia, the natural gas industry is booming. However, the regional constraints of natural gas should not be forgotten. ``et`` interviewed a representative of the BEB company about the prospects of the natural business at large and the primary energy source no. 2 in the German energy market, where natural gas ranks second after mineral oil. The topics reported refer to basic regulatory policy requirements in order to safeguard a smooth functioning of the gas market, as well as suitable environmental policy instruments and strategies for management re-orientation to cope with the expected changes in the competitive situation. (Orig.) [Deutsch] Ob weltweit, kontinentaleuropaeisch oder national betrachtet - das Erdgas ist dort wie hier auf dem Vormarsch. In Lateinamerika und Suedostasien kann man regelrecht von einem Erdgasboom sprechen. Allerdings sollte man die regionale Gebundenheit der Erdgasnutzung nicht aus den Augen verlieren. `et` sprach mit dem `Unternehmen Erdgas` BEB ueber die Perspektiven des - nach dem Mineraloel - Primaerenergietraegers Nr. 2 auf dem deutschen Markt. Neben der Auslotung von ordnungspolitischen Grunderfordernissen fuer einen funktionierenden Gasmarkt und geeigneten Instrumenten fuer den Umweltschutz geht es um die Strategien fuer eine unternehmerische Neuausrichtung fuer den verschaerften Wettbewerb.

    Full Text Available Introduction: One of the microbiological preparations used for this study was Effective Microorganisms (EM, being a commercial mixture of photosynthesizing bacteria, Actinomycetes, lactic acid bacteria, yeasts and fermenting fungi. The microbiological composition of the EM concentrateincludesStreptomyces albus, Propioni bacterium freudenreichil, Streptococcus lactis, Aspergillus oryzae, Mucor hiemalis, Saccharomycescerevisiae and Candida utilis. Moreover, EM also contains an unspecified amount of Lactobacillus sp. Rhodo pseudomonas sp. and Streptomyces griseus. Effective Microorganisms have a positive effect on the decomposition of organic matter, limiting putrefaction, increasing nitrogen content in the root medium of plants, phosphorus, improving soil fertility and as a result contributing to the growth and development of the root systems of plants. Selection of almond vegetative rootstocks for water stress tolerance is important for almond crop production in arid and semi-arid regions. The study of the eco-morphological characteristics that determine the success of a rootstock in a particular environment is a powerful tool for both agricultural management and breeding purposes. The aim of this work was to select the new rootstocks for water shortage tolerance, impact of water stress as well as Effective Microorganism (EM on morphological characteristics of almond rootstocks. Materials and Methods: In order to select the new rootstocks for water shortage tolerance, impact of water stress as well as EMonmorphologicalcharacteristics of almondrootstocks were studiedin thedepartment ofHorticulture, Ferdowsi University of Mashhad, in 2011-2012. The experiment was carried out with four replications in a completely random blockdesign to study the effects of two concentrations of EM (0 and 1%, three irrigation levels (normal irrigation 100%-control-and irrigation after depletion of 33 and 66% of available water, and four almond rootstocks including GF677 and selected natural hybrid of peach × almond (H1and H2, and almond vegetative rootstock (local control.In this study,EMtreatments for 60 days before stress treatments were applied so that in each irrigation, EM solution to a concentration of one percent was given to half of the experiment pots. Other pots were irrigated equally with normal water. Stress levels were applied from July as follow: full irrigation, watering after unloading 33% and 66% soil moisture availability. In order to evaluate the performance, seedling survival, plant growth, number of leaves, leaf area, root fresh and dry weight and leaves and root length were measured. Results and Discussion: Analysis of variance showed that between rootstock levels across all treatments were significantly differences at 0.01 level of probability. Comparison of means showed that the highest fresh and dry weight and leaf are awere observed forGF677and H1.Rootstockannualgrowth rate was also different. Most of the growth was related to the H1 Rootstocks. Thes urvival ratewas significantly different from the Rootstocks ofGF677,andH1showedthe highestpercentage of survival. The degree of adaptation to drought in varieties of almonds is different. The results showed that changes ingrowthparametersinGF677and H1were observed less often than other rootstocks. Because of strong roots,GF677and H1continue to attract more minerals under stress conditions. Analysis of variance showed that the between irrigation levels for all treatments were significantly different at 0.01 level of probability.

    Full Text Available Introduction: Strawberry (fragaria×ananassa Duch. fruit characterized by short storage life, often estimated last less than one week even under optimum conditions at 8°C. The loss of fruit quality is often caused by gray mold (Botrytis cinerea that is the most frequent reported postharvest disease in strawberry during storage (6. In recent years, considerable attention has given to elimination of synthetic chemical and fungicides application and development of various alternative strategies for controlling fruit and vegetables diseases (2. One strategy is replacement of natural products with plant origin such as essential oil and methyl salicylate (MeSA. Essential oils are volatile, natural and complex compounds characterized by a strong odor formed by aromatic plants in form of secondary metabolites. In nature, essential similar oils that extract from lavender (Lavandula angustifolia play an important role in protection of the plants against pathogen incidence that can be replaced by synthetic fungicides (1, 4 and 14. MeSA is also a volatile natural compound synthesized from salicylic acid which has an important role in the plant defense-mechanism, as well as plant growth and development (5, 19 and 20. Therefore, the main objective of this research was to study the effects of MeSA and lavender essential oil (LEO on decay control caused by Botrytis cinerea as well as post-harvest quality indices of strawberry fruits during cold storage. Material and Methods: First, antifungal activity was studied by using a contact assay (in vitro, which produces hyphal growth inhibition. Briefly, potato dextrose agar (PDA plates were prepared using 8 cm diameter glass petri dishes and inhibitory percentage was determined. For in-vivo assessment of LEO and MeSA effects on Botrytis-caused fungal disease control, the experiment was conducted as factorial in completely randomized design (CRD with 3 replicates. The treatments were 3 concentration of LEO including 0, 500 and 1000 µl L-1 and 3 level of MeSA including 0, 0.1 and 0.2 mM. After treatment, the fruits were inoculated by Botrytis suspension and transferred to storage and quality parameters were evaluated after 7, 14 and 21 days. At each sampling time, disease incidence, weight loss, titratable acidity, pH, soluble solids content, vitamin C and antioxidant activity were measured. Results and Discussion: The results showed that both LEO and MeSA treatments had significant effects on inhibition of mycelium growth within in-vitro condition (p < 0.05. Inhibition rate of mycelium growth significantly improved by LEO and MeSA concentration increase of, (Table 1. At in-vivo assessment, diseases incidence of treated fruits with 500 µl L-1 LEO and 0.1 mM MeSA were 32% and 64% lower than untreated fruits, respectively (Fig. 1 and 2. During storage period, the percentage of infected fruits increased. In addition, LEO and MeSA treatments affected quality parameters of strawberry fruits including titratable acidity, soluble solids content, vitamin C and antioxidant activity. Treated fruits had a high content of soluble solids, vitamin C and antioxidant activity in comparison to untreated fruits (Table 3 and 4. Probably ascorbic acid decreased through fungal infection duo to cell wall break down during storage. Any factors such as essential oil and salicylate that inhibit fungal growth can help preserving vitamin C in stored products. High level of vitamin C and antioxidant activity was observed in treated fruits with 0.1 mM MeSA and 500 µl L-1 LEO. In controlling weight loss of fruits, 0.2 mM of MeSA and 500 µl L-1 of LEO had significant effects, although MeSA was more effective than LEO treatments, possibly due to elimination of respiration rates and fungi infection (Table 4. Therefore, LEO and MeSA with fungicide effects could be replaced with synthetic fungicides in controlling fungal diseases of strawberry and maintain fruits quality during storage. Conclusion: In conclusion, our results showed that LEO and MeSA treatments could be safe and used to prevent infection of strawberry during storage, although LEO was more effective than MeSA treatments. Concentration of 500 μl L-1 of LEO and 0.1 mM MeSA could control fungal infection of fruits during storage. Also, LEO and MeSA treatments can extend shelf life for over the minimum period required to transit strawberries to foreign markets and without affecting quality, adversely. However, future studies are necessary to fully understand the mechanisms by which LEO and MeSA treatments may act as a fungicide and increase their postharvest life.

The literature addresses these issues conceptually, but lack an alignment between them that is evident in practice. As a method was used single case study. The report is as if the Sintonia project, developed by PRODESP - Data Processing Company of São Paulo. The results show the integration of project management processes with the Stage-Gate model developed during the project life cycle. The formalization of the project was defined in stages in which allowed the exploitation of economies of repetition and recombination to the development of new projects. This study contributes to the technical vision in dealing with the integration of project management processes. It was concluded that this system represents an attractive way, in terms of creating economic value and technological innovation for the organization.

    Embodied cognition accounts posit that concepts are grounded in our sensory and motor systems. An important challenge for these accounts is explaining how abstract concepts, which do not directly call upon sensory or motor information, can be informed by experience. We propose that metaphor is one important vehicle guiding the development and use of abstract concepts. Metaphors allow us to draw on concrete, familiar domains to acquire and reason about abstract concepts. Additionally, repeated metaphoric use drawing on particular aspects of concrete experience can result in the development of new abstract representations. These abstractions, which are derived from embodied experience but lack much of the sensorimotor information associated with it, can then be flexibly applied to understand new situations.

    This assessment is a feasibility study according to ISO 14024. It deals with the question whether an ecolabel is suitable for wood pellet heating systems and how concrete criteria for an ecolabel for wood pellet heating plants could be specified. The study begins with a comprehensive market analysis in order to identify possible plants for which an ecolabel would make sense. In the main part of the study, the environmental relevance of the chosen plants is analysed. For this analysis, plant manufacturers were interviewed and a comparison between wood pellet heating systems and heating systems which use gas, oil or wood was carried out. On the basis of this analysis, it was possible to derive a number of criteria which were discussed with company representatives and other experts in this field. As a result of this dialogue and the investigation process as a whole, the introduction of an ecolabel for wood pellet heating plants can be recommended. Wood pellet heating systems are characterized by their high level of automatation and the use of standardized fuels with constant high quality. Thus, they reach high combustion quality with low emission rates, and risks of misuse are minimized. They may contribute to the increased use of renewable energies and thereby to the achievement of climate protection goals. The proposed certification principles comprise requirements regarding (a) the efficient energy use (efficiency factor under partial load and nominal load, plant's supplementary energy consumption), (b) emission values for CO, NO{sub x}, dust and organic substances, (c) the offer of additional services, as well as (d) requirements with regard to the operating instructions. The transcription of the label is proposed as 'Ecolabel.. because low emission and energy-efficient'. (orig.)

    An improved concept for protection against electric shock current is presented for discussion among IEC, CENELEC, and DKE. In particular, the loop resistance presents a practical way of defining simple shutoff conditions especially in systems with a PE conductor. Further, a low-voltage protection concept is presented which would make the VDE 0100 more user-friendly. [German] Der Aufsatz stellt ein verbessertes Konzept fuer den Schutz gegen elektrischen Schlag vor; damit sollen weitere Diskussionen innerhalb der IEC, CENELEC und der DKE angeregt werden. Im Besonderen wird darauf hingewiesen, dass duerch den Schleifenwiderstand eine praxisfreundliche Moglichkeit besteht, speziell fuer Anlagen, in denen ein PE-Leiter installiert ist, einfache Ausschaltbedingungen aufgrund von Ausschaltstromfaktoren festzulegen. Weiter wird ein geandertes Schutzkleinspannungskonzept vorgestellt. Damit koennte dem weltverbreiteten Wunsch nach einer anwenderfreundlicheren VDE 0100 Rechnung getragen werden. (orig.)

    Already in the design stage of sliding bearings, optimal conditions for operation at a later stage should be envisaged. The contribution presents hints for optimal design and calculation of radial and axial bearings, e.g. gap design, optimised supporting strength, friction loss and lubricant throughput, lubricant exchange and lubricant heat exchange, and improved control of internal lubricant flow. [German] Bei der Auslegung von Gleitlagern ist es von Interesse, moeglichst optimale Bedingungen fuer den spaeteren Betrieb zu schaffen. Im vorliegenden Beitrag werden einige bereits bekannte und auch neue Hinweise zur optimalen Gestaltung und Berechnung, sowohl fuer Radial- als auch Axiallager gegeben. Dies betreffen im wesentlichen: die Gestaltung des Spaltverlaufs, Empfehlungen zur Optimierung der Tragfaehigkeit, der Reibungsverluste und des Schmierstoffdurchsatzes, Hinweise zum Schmierstoff- bzw. Schmierstoff-Waermeaustausch und die Verbesserung der inneren Schmierstofffuehrung. (orig.)

    There is an increasing demand for integrated building concepts in order to reduce energy consumption. Building design, construction and heating, ventilation and air-conditioning (HVAC) technology are decisive in this respect. Thus, an essentially higher energy efficiency is achieved and solar energy becomes the main energy source. An `active building envelope` assumes the task of controlling the energy flows between inside and outside. This paper reports on new components, system concepts and planning tools for solar building. (orig.) [Deutsch] Fuer zukuenftige Bauten werden in hohem Masse Forderungen nach integrierten Konzepten zur Begrenzung des Energieverbrauchs gestellt. Gestalt, Konstruktion und Klimatechnik sind dabei massgebliche Einflussfaktoren. Hierdurch wird eine wesentlich hoehere Energieeffizienz erzielt und Solarenergie kann die uebrigen Energiequellen zurueckdraengen. Eine `aktive Gebaeudehuelle` uebernimmt die Aufgabe, den Energiefluss zwischen Innen und Aussen zu steuern. Der Beitrag berichtet ueber neue Komponenten, Systemkonzepte und Planungswerkzeuge fuer das Solare Bauen. (orig.)

    1995-05-01

    The purpose of the present study was to work out a proposal for the development of a new organisation concept for hard coal mining in the Ruhr District. An appropriate starting point for an inquiry into the efficacy of an organisation concept is to study those factors governing business and its social environment that have been subject to great change during the past decades. In order to provide a basis for a proposal to this end the study first presents those factors governing the social environment that are relevant to an assessment. The most important factors of influence in the present context are the individual, his conception of his work, and his self-image; technology and its impact on the course of developments; and, examined here from a theoretical viewpoint, organisational structures that have actually been adopted in the past or have been suggested in the literature. Deliberations on these three areas provide a basis for developing and discussing new organisation concepts for hard coal underground mining. (orig./HS) [Deutsch] Das Ziel dieser Untersuchung ist, einen Vorschlag zur Entwicklung einer neuen Organisationsform im Steinkohlenbergbau an der Ruhr zu erarbeiten. Ausgangspunkt fuer eine Fragestellung im Hinblick auf die Zweckmaessigkeit einer Organisationsform ist die Beobachtung der Entwicklung der Betriebs- und Umweltbedingungen, die sich im Verlauf der letzten Jahrzehnte wesentlich gewandelt haben. Um eine Basis fuer einen solchen Vorschlag zu schaffen, sind zuerst die Umweltbedingungen dargelegt worden, die fuer eine Beurteilung von Bedeutung sind. In diesem Zusammenhang sind von Einfluss im wesentlichen der Mensch und seine Beziehungen zu Arbeit und gesellschaftlichem Selbstverstaendnis, die Technik und die Auswirkungen ihrer Weiterentwicklung im Zeitablauf sowie die theoretische Betrachtung von Organisationsstrukturen, die in der Vergangenheit in die Praxis eingefuehrt bzw. in der Literatur beschrieben worden sind.

    The paper describes the use of online simulation for prognosticating plant behaviour, training plant operators, and for obtaining state data not to be obtained otherwise. Whereas, for the mathematical modelling of the process, the established approaches Activated Sludge Model (ASM) 1 and 2 could be reverted to, new methodics needed to be developed for continuous model tracking in order to solve the conflict between a large number of parameters in the model and scarce online measuring data on the spot. The result is a practicable solution which harnesses available knowledge concerning the significance of suitable parameters for model adaptation. First of all, essential demands on and objectives of a process observer for sewage treatment plants are elaborated. Then a software system is described with reference to successful pilot installations which permits model-based process control and remote monitoring of sewage treatment plant. (orig.) [German] Der Beitrag beschreibt die Nutzung der Online-Simulation fuer die Prognose des Anlagenverhaltens, das Training der Anlagenfahrer und die Gewinnung ansonsten nicht messbarer Zustandsinformationen. Waehrend fuer die mathematische Modellierung des Prozesses auf die etablierten Ansaetze ASM 1 und 2 (Activated Sludge Model) zurueckgegriffen werden konnte, musste fuer die laufende Modellnachfuehrung eine neue Methodik entwickelt werden, um den Konflikt zwischen grosser Parameteranzahl im Modell und geringer Online-Messinformation vor Ort zu loesen. Das Ergebnis ist eine praktikable Loesung, die das vorhandene Wissen um die Signifikanz zur Modellanpassung geeigneter Parameter ausnutzt. In den folgenden Ausfuehrungen werden zunaechst wesentliche Anforderungen und Zielstellungen eines Prozessbeobachters fuer Klaeranlagen herausgearbeitet. Unter Bezugnahme auf erfolgreiche Pilotinstallationen wird anschliessend ein Software-System vorgestellt, das eine modellgestuetzte Betriebsfuehrung und Fernueberwachung von Klaeranlagen

    The application of modern simulation tools offering additional support during the vehicle development process is accepted to a large extent by most car manufacturers. Just like new model-based control strategies, these simulation investigations require very accurate - and thus very complex - models of vehicle dynamics, which can be processed in real time. As an example of such a vehicle model, this article describes a real-time vehicle simulation model which was developed at the Institute of Automatic Control at Darmstadt University of Technology, in co-operation with the ITDC of the Adam OPEL AG. By applying modern adaptation techniques, this vehicle model is able to calculate onboard the important variables describing the actual driving state even if the environmental conditions change. (orig.) [German] Der Einsatz von Simulationswerkzeugen zur Unterstuetzung der Fahrzeugentwicklung hat sich bei den meisten Automobilherstellern weitgehend durchgesetzt. Ebenso wie neuartige modellbasierte Regelstrategien verlangen diese Simulationsuntersuchungen nach immer exakteren - und damit komplexeren - fahrdynamischen Modellen, die in Echtzeit ausgewertet werden. Als Beispiel fuer ein solches Gesamtfahrzeugmodell beschreibt dieser Beitrag ein echtzeitfaehiges Modell fuer die Bewegung des Fahrzeugs um alle drei Hauptachsen, das am Institut fuer Automatisierungstechnik der TU Darmstadt in Kooperation mit dem Internationalen Technischen Entwicklungszentrum (ITEZ) der Adam Opel AG entwickelt wurde. Es ist durch den Einsatz von Adaptionsmethoden in der Lage, wichtige fahrdynamische Zustandsgroessen im Fahrzeug auch unter veraenderlichen Umgebungsbedingungen zu ermitteln. (orig.)

    To remain internationally competitive company managements in the German coal mining industry must effectively use market opportunities on foreign coal markets. It is shown below that there can be no uniform, globally successful marketing strategy for the international coal market. Instead different marketing strategies specific to the countries should be implemented for commitments in the individual coal-producing countries. Such marketing strategies should be based on situation analyses of the individual coal-producing countries, which should be supplemented by opportunity/risk analyses. The systematology introduced for this purpose in based on the model of the product life cycle. The description concentrates on the coalproducing sector. (orig.) [Deutsch] Prognosen renommierter Institutionen lassen erwarten, dass die Steinkohlenbranche weltweit in den naechsten Jahrzehnten noch Wachstumspotentiale besitzt. Durch Nutzung dieser Potentiale im Zug einer Internationalisierung kann die deutsche Steinkohlenbranche schrumpfende Inlandsproduktion ersetzen. Im vorliegenden Beitrag wird gezeigt, dass es hierfuer keinen Koenigsweg einer einheitlichen, global erfolgreichen Marketingstrategie fuer den Weltsteinkohlenmarkt geben kann. Statt dessen sind laenderspezifisch differenziert gestaltete Marketingstrategien fuer Engagements in den einzelnen Kohlelaendern umzusetzen. Solche Marketingstrategien sollten auf Situationsanalysen der einzelnen Kohlelaender beruhen, die durch Chancen-/Risikenanalysen zu ergaenzen sind. Die hierzu vorgestellte Systematik beruht auf dem Modell des Produktlebenszyklus. Im Mittelpunkt der Darstellung steht der steinkohlenproduzierende Bereich. Basis fuer internationale Engagements sind vorhandene Kernkompetenzen. Zur erfolgreichen Realisierung solcher Strategien scheint die Organisationsform der Netzwerk-Organisation zweckmaessig zu sein.

    The interaction between environmental factors and genetic determinants is crucial for the development of malignant tumours. However, the hereditary factors involved in the development of cancer that have been recognised so far are only responsible for at the most ten percent of tumours. It is still a matter of dispute whether the remaining 90 percent - so-called sporadic tumours - really have a cause that is free of genetic influence. There are good reasons for believing that there are a large number of genes in the human genome that confer resistance or susceptibility for tumorigenesis, and thus lead to natural genetic variability. (orig.) [German] Die Wechselwirkung von Umweltfaktoren und genetischen Determinanten ist entscheidend fuer die Entstehung von malignen Tumoren. Die bisher bekannten an der Krebsentstehung beteiligten erheblichen Faktoren sind allerdings fuer hoechstens zehn Prozent aller auftretenden Tumoren verantwortlich. Nach wie vor umstritten ist, ob die verbleibenden 90 Prozent - die sogenannten sporadischen Tumoren - tatsaechlich eine Ursache ohne erhebliche Komponente haben. Es gibt aber gute Gruende anzunehmen, dass im menschlichen Erbgut eine Vielzahl von Genen existiert, die Resistenz beziehungsweise Empfindlichkeit (Suszeptibilitaet) fuer die Tumorigenese vermitteln und so zu der natuerlichen genetischen Variabilitaet fuehren.

  9. The Complexity of Abstract Machines

    2017-01-01

    Full Text Available The lambda-calculus is a peculiar computational model whose definition does not come with a notion of machine. Unsurprisingly, implementations of the lambda-calculus have been studied for decades. Abstract machines are implementations schema for fixed evaluation strategies that are a compromise between theory and practice: they are concrete enough to provide a notion of machine and abstract enough to avoid the many intricacies of actual implementations. There is an extensive literature about abstract machines for the lambda-calculus, and yet—quite mysteriously—the efficiency of these machines with respect to the strategy that they implement has almost never been studied. This paper provides an unusual introduction to abstract machines, based on the complexity of their overhead with respect to the length of the implemented strategies. It is conceived to be a tutorial, focusing on the case study of implementing the weak head (call-by-name strategy, and yet it is an original re-elaboration of known results. Moreover, some of the observation contained here never appeared in print before.

Historically, there have been three major strategies for dealing with such problems: semigroup, abstract distribution, and regularization methods. Semigroup and distribution methods restore well-posedness, in a modern weak sense. Regularization methods provide approximate solutions to ill-posed problems. Although these approaches were extensively developed over the last decades by many researchers, nowhere could one find a comprehensive treatment of all three approaches.Abstract Cauchy Problems: Three Approaches provides an innovative, self-contained account of these methods and, furthermore, demonstrates and studies some of the profound connections between them. The authors discuss the application of different methods not only to the Cauchy problem that is not well-posed in the classical sense, b...

  17. Learning abstract algebra with ISETL

    CERN Document Server

    Dubinsky, Ed

    1994-01-01

    Most students in abstract algebra classes have great difficulty making sense of what the instructor is saying. Moreover, this seems to remain true almost independently of the quality of the lecture. This book is based on the constructivist belief that, before students can make sense of any presentation of abstract mathematics, they need to be engaged in mental activities which will establish an experiential base for any future verbal explanation. No less, they need to have the opportunity to reflect on their activities. This approach is based on extensive theoretical and empirical studies as well as on the substantial experience of the authors in teaching astract algebra. The main source of activities in this course is computer constructions, specifically, small programs written in the mathlike programming language ISETL; the main tool for reflections is work in teams of 2-4 students, where the activities are discussed and debated. Because of the similarity of ISETL expressions to standard written mathematics...

  4. In-Package Chemistry Abstraction

    Energy Technology Data Exchange (ETDEWEB)

    2003-07-21

    The work associated with the development of this model report was performed in accordance with the requirements established in ''Technical Work Plan for Waste Form Degradation Modeling, Testing, and Analyses in Support of SR and LA'' (BSC 2002a). The in-package chemistry model and in-package chemistry model abstraction are developed to predict the bulk chemistry inside of a failed waste package and to provide simplified expressions of that chemistry. The purpose of this work is to provide the abstraction model to the Performance Assessment Project and the Waste Form Department for development of geochemical models of the waste package interior. The scope of this model report is to describe the development and validation of the in-package chemistry model and in-package chemistry model abstraction. The in-package chemistry model will consider chemical interactions of water with the waste package materials and the waste form for commercial spent nuclear fuel (CSNF) and codisposed high-level waste glass (HLWG) and N Reactor spent fuel (CDNR). The in-package chemistry model includes two sub-models, the first a water vapor condensation (WVC) model, where water enters a waste package as vapor and forms a film on the waste package components with subsequent film reactions with the waste package materials and waste form--this is a no-flow model, the reacted fluids do not exit the waste package via advection. The second sub-model of the in-package chemistry model is the seepage dripping model (SDM), where water, water that may have seeped into the repository from the surrounding rock, enters a failed waste package and reacts with the waste package components and waste form, and then exits the waste package with no accumulation of reacted water in the waste package. Both of the submodels of the in-package chemistry model are film models in contrast to past in-package chemistry models where all of the waste package pore space was filled with water. The

    This viewgraph presentation reviews the concept of the Operating System Abstraction Layer (OSAL) and its benefits. The OSAL is A small layer of software that allows programs to run on many different operating systems and hardware platforms It runs independent of the underlying OS & hardware and it is self-contained. The benefits of OSAL are that it removes dependencies from any one operating system, promotes portable, reusable flight software. It allows for Core Flight software (FSW) to be built for multiple processors and operating systems. The presentation discusses the functionality, the various OSAL releases, and describes the specifications.

    (Abstract only) The commercial exploitation of microwave frequencies for cellular, WiFi, Bluetooth, HDTV, and satellite digital media transmission has brought down the cost of the components required to build an effective radio telescope to the point where, for the cost of a good eyepiece, you can construct and operate a radio telescope. This paper sets forth a family of designs for 1421 MHz telescopes. It also proposes a method by which operators of such instruments can aggregate and archive data via the Internet. With 90 or so instruments it will be possible to survey the entire radio sky for transients with a 24 hour cadence.

    Let K be an Abstract Elementary Class. Under the asusmptions that K has a nicely behaved forking-like notion, regular types and existence of some prime models we establish a decomposition theorem for such classes. The decomposition implies a main gap result for the class K. The setting is general enough to cover \\aleph_0-stable first-order theories (proved by Shelah in 1982), Excellent Classes of atomic models of a first order tehory (proved Grossberg and Hart 1987) and the class of submodels of a large sequentially homogenuus \\aleph_0-stable model (which is new).

  12. An introduction to abstract algebra

    CERN Document Server

    Robinson, Derek JS

    2003-01-01

    This is a high level introduction to abstract algebra which is aimed at readers whose interests lie in mathematics and in the information and physical sciences. In addition to introducing the main concepts of modern algebra, the book contains numerous applications, which are intended to illustrate the concepts and to convince the reader of the utility and relevance of algebra today. In particular applications to Polya coloring theory, latin squares, Steiner systems and error correcting codes are described. Another feature of the book is that group theory and ring theory are carried further than is often done at this level. There is ample material here for a two semester course in abstract algebra. The importance of proof is stressed and rigorous proofs of almost all results are given. But care has been taken to lead the reader through the proofs by gentle stages. There are nearly 400 problems, of varying degrees of difficulty, to test the reader''s skill and progress. The book should be suitable for students ...

  13. Reconstruction of abstract quantum theory

    International Nuclear Information System (INIS)

    Drieschner, M.; Goernitz, T.; von Weizsaecker, C.F.

    1988-01-01

    Understanding quantum theory as a general theory of prediction, we reconstruct abstract quantum theory. Abstract means the general frame of quantum theory, without reference to a three-dimensional position space, to concepts like particle or field, or to special laws of dynamics. Reconstruction is the attempt to do this by formulating simple and plausible postulates on prediction in order to derive the basic concepts of quantum theory from them. Thereby no law of classical physics is presupposed which would then have to be quantized. We briefly discuss the relationship of theory and interpretation in physics and the fundamental role of time as a basic concept for physics. Then a number of assertions are given, formulated as succinctly as possible in order to make them easily quotable and comparable. The assertations are arranged in four groups: heuristic principles, verbal definitions of some terms, three basic postulates, and consequences. The three postulates of separable alternatives, indeterminism, and kinematics are the central points of this work. These brief assertions are commented upon, and their relationship with the interpretation of quantum theory is discussed. Also given are an outlook on the further development into concrete quantum theory and some philosophical reflections

    Within the frame of this project, a concept for setting up exemplary emission inventories for water was put forward. An overview is given of the international activities on emission inventories and the status of national emission inventories. Based on the data situation in Germany, it was necessary to include both plant-specific, aggregated and calculated data of the point sources in the inventories. Due to their increasing significance, diffuse material emissions into water were also taken into account. Based on the conceptual work, exemplary emission inventories were compiled for nitrogen, phosphorous and adsorbable organic combined halides (AOX) as well as the heavy metals arsenic, cadmium, chrome, copper, mercury, nickel, lead and zinc. These were evaluated according to the areas of origin (sectors) or the emission paths as well as according to the large river basins Danube, Rhine, Ems, Weser, Elbe, Oder, North Sea and Baltic Sea. In addition, lists of the ten largest industrial direct dischargers were compiled. (orig.) [German] Im Rahmen dieses Vorhabens wurde ein Konzept fuer die Erstellung von beispielhaften Emissionsinventaren fuer Gewaesser erarbeitet. Es wird ein Ueberblick ueber die internationalen Aktivitaeten zu Emissionsinventaren und den Stand beim Aufbau von nationalen Emissionsinventaren gegeben. Auf Grund der Datensituation in Deutschland war es erforderlich, dass sowohl anlagenspezifische als auch aggregierte sowie berechnete Daten der Punktquellen in die Inventare einbezogen wurden. Wegen ihrer zunehmenden Bedeutung werden die diffusen Stoffeintraege in die Gewaesser ebenfalls beruecksichtigt. Aufbauend auf den konzeptionellen Arbeiten wurden beispielhafte Emissionsinventare fuer Stickstoff, Phosphor und adsorbierbare organisch gebundene Halogene (AOX) sowie die Schwermetalle Arsen, Cadmium, Chrom, Kupfer, Quecksilber, Nickel, Blei und Zink zusammengestellt.

    2000-07-01

    New radiobiological findings like genomic instability and genetic predisposition did not only give an impetus to research activities but prompted also the assumption that radiation protection has to be revised. This paper outlines possible consequences for the practically relevant area of low doses. It begins with a discussion of damage distributions after low dose exposure including a critical evaluation of the applicability of this quantity. The radiobiological findings which started the present discussion are briefly summarised as well as the results of new studies in genetics. Possible consequences might be envisaged for the evaluation of epidemiological investigations, both with regard to radiation related cancer risk as well as to the possible occurrence of radiation-related non-cancer diseases. In conclusion it is stated that the new findings will not lead to an upward revision of present risk factors and hence there is no need for fundamental changes of the current system of radiation protection. (orig.) [German] Neuere strahlenbiologische Erkenntnisse wie genomische Instabilitaet und genetische Praedisposition haben nicht nur die Forschung befluegelt, sondern auch die Vermutung genaehrt, dass neue Ueberlegungen zum Strahlenschutz angestellt werden muessen. In diesem Beitrag werden moegliche Konsequenzen fuer den praktisch wichtigen Bereich niedriger Dosen diskutiert. Am Anfang steht zunaechst eine Betrachtung ueber die Schadensverteilung im niedrigen Dosisbereich, die eine kritische Wertung der Anwendbarkeit dieser Groesse einschliesst. Die strahlenbiologischen Befunde, welche die Diskussion angestossen haben, werden ebenso skizziert wie die genetische Ausgangslage. Konsequenzen werden gesehen fuer die Bewertung epidemiologischer Studien sowohl fuer die Abschaetzung des Krebsrisikos als auch der Moeglichkeit der Strahlenbedingtheit anderer Erkrankungen. Als Schlussfolgerung wird festgestellt, dass die neuen Befunde nicht zu einer Erhoehung der gegenwaertig

    CERN Document Server

    Lee, Gregory T

    2018-01-01

    This carefully written textbook offers a thorough introduction to abstract algebra, covering the fundamentals of groups, rings and fields. The first two chapters present preliminary topics such as properties of the integers and equivalence relations. The author then explores the first major algebraic structure, the group, progressing as far as the Sylow theorems and the classification of finite abelian groups. An introduction to ring theory follows, leading to a discussion of fields and polynomials that includes sections on splitting fields and the construction of finite fields. The final part contains applications to public key cryptography as well as classical straightedge and compass constructions. Explaining key topics at a gentle pace, this book is aimed at undergraduate students. It assumes no prior knowledge of the subject and contains over 500 exercises, half of which have detailed solutions provided.

  18. Abstract Expression Grammar Symbolic Regression

    Science.gov (United States)

    Korns, Michael F.

    This chapter examines the use of Abstract Expression Grammars to perform the entire Symbolic Regression process without the use of Genetic Programming per se. The techniques explored produce a symbolic regression engine which has absolutely no bloat, which allows total user control of the search space and output formulas, which is faster, and more accurate than the engines produced in our previous papers using Genetic Programming. The genome is an all vector structure with four chromosomes plus additional epigenetic and constraint vectors, allowing total user control of the search space and the final output formulas. A combination of specialized compiler techniques, genetic algorithms, particle swarm, aged layered populations, plus discrete and continuous differential evolution are used to produce an improved symbolic regression sytem. Nine base test cases, from the literature, are used to test the improvement in speed and accuracy. The improved results indicate that these techniques move us a big step closer toward future industrial strength symbolic regression systems.

    Nephrogenic systemic fibrosis (NSF) is a systemic disease with a 5% mortality which was first described in 1997 and which only occurs in patients with severely impaired renal function (GFR <30 ml/min per 1.73 m{sup 2}) and for which an association with previous administration of several Gd-chelates has been observed. According to retrospective case control studies the odds ratio for a patient with severely impaired renal function to develop NSF was increased by a factor of 22-32 when gadodiamide was administered. At this time there are approximately 250 confirmed cases of NSF of which 177 are associated with the administration of gadodiamide and 78 are associated with gadopentetate dimeglumine. This review article elucidates the postulated pathogenesis of NSF and provides an overview of the published statements and recommendations from international regulatory authorities and from international advisory boards. Even though the pathogenesis is not completely understood at this time, the European Pharmacovigilance Working Party has decided that gadodiamide and gadopentetate dimeglumine must not be used in high-risk patients. Other Gd-containing contrast agents should only be administered after thorough assessment of the indication and with minimized Gd dose. In the USA, the FDA has issued a black box warning for Gd-containing contrast agents. (orig.) [German] Die nephrogene systemische Fibrose (NSF) ist eine 1997 erstmals beschriebene systemische Erkrankung mit einer 5%igen Mortalitaet, die bislang ausschliesslich bei Patienten mit terminaler Niereninsuffizienz (glomerulaere Filtrationsrate [GFR] <30 ml/min/1,73 m{sup 2}) aufgetreten ist und fuer die eine Assoziation mit der vorherigen Verabreichung verschiedener Gadolinium- (Gd-)haltiger MR-Kontrastmittel beobachtet wurde. Laut retrospektiver Fall-Kontroll-Studien war die Odds Ratio fuer die Entwicklung einer NSF bei Patienten mit stark eingeschraenkter Nierenfunktion 22- bis 32-fach hoeher, wenn Gadodiamid

    Purpose: For preoperative staging of colorectal cancer a CT scan is frequently performed. This report examines the sensitivity of CT for regional lymph node metastasis of colorectal cancer using different criteria. Materials and methods: Preoperative CT scans of 153 patients with colorectal cancer were analyzed using different criteria for N1. The results were then compared to the postoperative histological findings. Results: For N1=lymph nodes (LN)>1 cm the sensitivity was 47%. For N1=LN>1 cm or an increased number of LN<1 cm the sensitivity was 71%. In patients with a primary tumor seen on CT, sensitivity rose to 87%. Discussion: Evidence of regional nodal metastatic disease is only relevant for rectal cancer, colon polyps, and for locally excised tumors when considering present surgical concepts for the treatment of colorectal cancer. In these cases CT analysis using the broadened criteria for N1 proposes a valuable argument regarding possible preoperative radiotherapy or an operative revision. (orig.) [Deutsch] Die Sensitivitaet fuer den Nachweis regionaerer Lymphknotenmetastasen kolorektaler Karzinome wurde unter Anwendung verschiedener Kriterien fuer das N1-Stadium an Patienten mit histologisch gesichertem Lymphknotenbefund untersucht. Fuer das Kriterium N1=Lymphknoten (LK)>1 cm betrug die Sensitivitaet 47%. Fuer N1=LK>1 cm/vermehrte Anzahl LK<1 cm war sie 71%, bei erkennbarem Primaertumor sogar 87%. Unter Beruecksichtigung der derzeit geltenden operativen Therapiekonzepte ist der Nachweis von regionaeren Lymphknotenmetastasen nur bei Rektumkarzinom bzw. fuer Kolonpolypen oder fuer lokal exzidierte Karzinome fuer das therapeutische Vorgehen relevant. In diesen Faellen leistet die CT mit den erweiterten Kriterien fuer ein N1-Stadium trotz hoeherer falsch-positiver Raten eine wertvolle Hilfestellung fuer die Entscheidung ueber eine neoadjuvante Bestrahlung oder eine Nachresektion.

    The second international EURORIB conference 'EURORIB'10' will be held from June 6. to June 11. 2010 in Lamoura (France). Our nuclear physics community is eagerly awaiting the construction of the next generation of Radioactive Ion Beam (RIB) facilities in Europe: HIE-ISOLDE at CERN, NUSTAR at FAIR, SPES at LNL, SPIRAL2 at GANIL and the future EURISOL. The collaborations built around these facilities are exploring new experimental and theoretical ideas that will advance our understanding of nuclear structure through studies of exotic nuclei. Following in the spirit of the conference held in Giens in 2008, EURORIB'10 will provide the opportunity for the different collaborations to come together and present these ideas, and explore the synergy between the research programmes based around the hypothetical severe acprojects.

  8. WD1145+017 (Abstract)

    (Abstract only) WD1145 is a 17th magnitude white dwarf star 570 light years away in Virgo that was discovered to have a disintegrating planetoid in close orbit by Andrew Vanderburg, a graduate student at Harvard CfA, while data mining the elucidate the nature of its rather bizarre transit light curves. I obtained multiple observations of WD1145 over the course of a year, and found a series of complex transit light curves that could only be interpreted as a ring complex or torus in close orbit around WD1145. Combined with data from other amateur astronomers, professional observations, and satellite data, it became clear that WD1145 has a small planetoid in close orbit at the Roche limit and is breaking apart, forming a ring of debris material that is then raining down on the white dwarf. The surface of the star is "polluted" by heavy metals, determined by spectroscopic data. Given that in the intense gravitational field of a white dwarf any heavy metals could not for long last on the surface, this confirms that we are tracking in real time the destruction of a small planet by its host star.

  9. ABSTRACT MODELS FOR SYSTEM VIRTUALIZATION

    Directory of Open Access Journals (Sweden)

    2015-05-01

    Full Text Available The paper is dedicated to issues of system objects securing (system files and user system or application configuration files against unauthorized access including denial of service attacks. We have suggested the method and developed abstract system virtualization models, which are used toresearch attack scenarios for different virtualization modes. Estimation for system tools virtualization technology effectiveness is given. Suggested technology is based on redirection of access requests to system objects shared among access subjects. Whole and partial system virtualization modes have been modeled. The difference between them is the following: in the whole virtualization mode all copies of access system objects are created whereon subjects’ requests are redirected including corresponding application objects;in the partial virtualization mode corresponding copies are created only for part of a system, for example, only system objects for applications. Alternative solutions effectiveness is valued relating to different attack scenarios. We consider proprietary and approved technical solution which implements system virtualization method for Microsoft Windows OS family. Administrative simplicity and capabilities of correspondingly designed system objects security tools are illustrated on this example. Practical significance of the suggested security method has been confirmed.

  10. An abstract approach to music.

    Energy Technology Data Exchange (ETDEWEB)

    Kaper, H. G.; Tipei, S.

    1999-04-19

    In this article we have outlined a formal framework for an abstract approach to music and music composition. The model is formulated in terms of objects that have attributes, obey relationships, and are subject to certain well-defined operations. The motivation for this approach uses traditional terms and concepts of music theory, but the approach itself is formal and uses the language of mathematics. The universal object is an audio wave; partials, sounds, and compositions are special objects, which are placed in a hierarchical order based on time scales. The objects have both static and dynamic attributes. When we realize a composition, we assign values to each of its attributes: a (scalar) value to a static attribute, an envelope and a size to a dynamic attribute. A composition is then a trajectory in the space of aural events, and the complex audio wave is its formal representation. Sounds are fibers in the space of aural events, from which the composer weaves the trajectory of a composition. Each sound object in turn is made up of partials, which are the elementary building blocks of any music composition. The partials evolve on the fastest time scale in the hierarchy of partials, sounds, and compositions. The ideas outlined in this article are being implemented in a digital instrument for additive sound synthesis and in software for music composition. A demonstration of some preliminary results has been submitted by the authors for presentation at the conference.

    The Forest State Report 2012 systematically records the health status of the forest resources in the country on a scientific basis. Environmental information is measured, recorded and evaluated in the context of forest environmental monitoring using a measuring network. More than a third of the forest area has suffered significant damage. The share of undamaged forest areas has declined by almost one third to 26 percent since last year. Compared to the previous year, the crown damage increased by an average of 2.5 percentage points. More important, however, is the fact that for the two main tree species spruce and beech since the turn of the millennium, there has been a marked increase in the damage intensity for all age groups. [German] Der Waldzustandsbericht 2012 erfasst auf wissenschaftlicher Basis systematisch den Gesundheitszustand der Waldbestaende im Land. Im Rahmen des Forstlichen Umweltmonitorings werden mit Hilfe eines Messnetzes Umweltinformationen gemessen, erfasst und ausgewertet. Ueber ein Drittel der Waldflaeche weist deutliche Schaeden auf. Der Anteil der ungeschaedigten Waldflaechen ist seit dem letzten Jahr um fast ein Drittel auf 26 Prozent zurueckgegangen. Die Kronenschaeden haben gegenueber dem Vorjahr um durchschnittlich 2,5 Prozentpunkte zugenommen. Wichtiger ist jedoch der Befund, dass fuer die beiden Hauptbaumarten Fichte und Buche seit der Jahrtausendwende ein deutlicher Anstieg der Schadensintensitaet fuer alle Altersklassen zu beobachten ist.

    In Baden-Wuerttemberg, the state of forests has been recorded since the 1980s in the course of an annual forest status report. In 2015, a decline in forest damage can be reported. As an indicator for the evaluation of the forest state, the crown condition of the trees applies. The average crown defoliation has been reduced by two percentage points to around 24 percent, while the share of healthy forest areas increased by five percentage points to a total of 29 percent. The clearly damaged forest areas decreased by six percentage points to 36 percent. Concerns are causing a relatively new fungus disease in the tree species ash, the ash dieback. [German] In Baden-Wuerttemberg wird der Zustand der Waelder seit den 1980er Jahren im Zuge eines jaehrlichen Waldzustandsberichtes erfasst. Fuer das Jahr 2015 kann erfreulicherweise einen Rueckgang der Waldschaeden verzeichnet werden. Als Indikator fuer die Beurteilung des Waldzustandes gilt der Kronenzustand der Baeume. Die durchschnittliche Kronenverlichtung hat sich um zwei Prozentpunkte auf rund 24 Prozent verringert, waehrend sich der Anteil der gesunden Waldflaeche um fuenf Prozentpunkte auf insgesamt 29 Prozent erhoehte. Die deutlich geschaedigten Waldflaechen verringerten sich um sechs Prozentpunkte auf 36 Prozent. Sorgen bereitet eine relativ neue Pilzerkrankung bei der Baumart Esche, das Eschentriebsterben.

    One of the aims of environmental research at the GSF Research Centre for the Environment and Health is to determine the behaviour of environmentally consequential chemicals in terrestrial ecosystems under as natural conditions as possible. The GSF lysimeter plant in Neuherberg permits studying the environmental behaviour of organic chemicals in different soils. Collaborators at GSF have developed a means of applying -14-marked substances in field lysimeters so as to be able to refind released chemicals, identify their conversion products and set up mass balances for the chemicals. [Deutsch] Ein Ziel der Umweltforschung im GSF-Forschungszentrum fuer Umwelt und Gesundheit ist es, das Verhalten von Umweltchemikalien in terrestrischen Oekosystemen unter moeglichst natuerlichen Bedingungen zu bestimmen.

    At present, selection of procedures for inservice inspection has to take into account the legal basis, i.e. the existing regulatory codes, and the practical aspects, i.e. experience and information obtained by the general, initial inservice inspection or performance data obtained by the latest, recurrent inspection. However, regulatory codes are being reviewed to a certain extent in order to permit integration of technological progress. Depending on the degree of availability in future, of inspection task-specific, sensitive and qualified NDE techniques for inservice inspections (`risk based ISI`), the framework of defined inspection intervals, sites, and detection limits will be broken up and altered in response to progress made. This opens up new opportunities for an optimization of inservice inspections for proof of component integrity. (orig./CB) [Deutsch] Zur Zeit muss sich die Auswahl der Pruefverfahren an den gueltigen Regelwerken und, da es sich um wiederkehrende Pruefungen handelt, an der Basispruefung bzw. der letzten wiederkehrenden Pruefung orientieren. Jedoch vollzieht sich zur Zeit eine Oeffnung der Regelwerke, mit der man auch der Weiterentwicklung der Prueftechniken Rechnung traegt. In dem Masse, wie zukuenftig auf die Pruefaufgabe/Pruefaussage optimal abgestimmte und qualifizierte Prueftechniken mit einer hohen Nachweisempfindlichkeit am Bauteil fuer zielgerichtete wiederkehrende Pruefungen (als `risk based ISI`) zur Verfuegung stehen, wird der Rahmen mit festgelegten Pruefintervallen, Prueforten und festen Registriergrenzen gesprengt und variabel gestaltet werden koennen. Damit ergeben sich neue Moeglichkeiten fuer eine Optimierung der WKP zum Nachweis der Integritaet des Bauteils. (orig./MM)

    Increasing competition and changing markets in the energy sector make new demands on cost management and at the same time on the quality to be provided by the costing systems. The process cost calculation used today in various branches of industry is able to contribute - by orientating itself to processes and chains of delivered value - to an assignment of costs doing more justice to the causes so that costing information with improved meaningfulness is available for entrepreneurial decisions. The authors introduce process cost calculation and illustrate its function using a practice-related example for its application. Potential fields of utilisation in the electricity supply enterprises are subsequently shown. (orig.) [Deutsch] Zunehmender Wettbewerb und sich wandelnde Maerkte im Energiesektor stellen neue Anforderungen an das Kostenmanagement und damit auch an die Qualitaet der von den Kostenrechnungssystemen bereitzustellenden Informationen. Die heute in verschiedenen Wirtschaftszweigen eingesetzte Prozesskostenrechnung kann - durch Orientierung an Prozessen und Wertschoepfungsketten - zu einer verursachungsgerechteren Kostenzuordnung beitragen, so dass fuer unternehmerische Entscheidungen Kostenrechnungsinformationen mit verbesserter Aussagekraft zur Verfuegung stehen. Die Verfasser stellen die Prozesskostenrechnung vor und veranschaulichen deren Funktionsweise anhand eines praxisbezogenen Anwendungsbeispiels. Im Anschluss werden moegliche Einsatzgebiete fuer Energieversorgungsunternehmen aufgezeigt. (orig.)

  18. Communicating to gain public acceptance of energy projects; Akzeptanzkommunikation fuer Energieprojekte

    Whoever plans to execute energy projects in today's world should be aware of the fact that the social framework conditions surrounding such projects have changed significantly. For the organization executing the project to merely adhere to the legally prescribed authorization procedure and leave it until the end of the planning procedure to inform those affected is often no longer sufficient for gaining public acceptance. Large parts of the population criticise the usual procedures because they have lost confidence in this kind of decision making, which offers them too little scope for co-determination. Thus for some years there has been a growing number of cases where citizens demand full public participation and early information on why the project in question is needed and what kinds of impact it will have. Lack of acceptance can lead to resistance, with negative effects on the project and the companies involved. TECSOL takes care of the communication management alongside energy projects, taking its bearings by the existing standards for voluntary early information of the public, as recommended by the VDI (Guideline 7001) and required by the legislature (PlVereinhG = Law for Improvement of Public Participation and Harmonisation of Plan Approval Procedures). The lecture outlines the societal challenges involved as well as the possibilities for dealing fairly with demands of the population in the context of energy projects. This is illustrated using the model case of the ''Etzel cultural landscape'' as a practical example, in which TECSOL played a prominent role on behalf of IVG Caverns GmbH. [German] Wer heute Energieprojekte umsetzen will, muss sich im Klaren darueber sein, dass sich die gesellschaftlichen Rahmenbedingungen stark veraendert haben.

    und die Erstellung eines einheitlichen Berechnungsansatzes. Als Grundlage fuer die durchgefuehrten Berechnungen dienten die deutschen Vorschriften der aktuellen Energieeinsparverordnung in Kombination mit der Berechnungsnorm DIN 4108-6 sowie DIN 4701-10. Hierzu wurden die klimatischen Bedingungen Russlands am Beispiel der russischen Metropole Sankt Petersburg in die Berechnungen integriert. Die Datenanalyse des Bestandsgebaeudes eroeffnet eine grosse Bandbreite an Moeglichkeiten zur Erhoehung der Energieeffizienz. So wird unter anderem im Zuge der Berechnungen festgestellt, dass durch relativ kostenguenstige Massnahmen zur Verbesserung des Waermeschutzes eine bedeutende Verringerung des Endenergiebedarfs erreicht werden kann. Es werden weiterhin moegliche Sanierungsvarianten unter Einbeziehung verschiedener Materialien und Heizungsanlagen vorgestellt. Die Ergebnisse machen deutlich, dass die Zukunft russischer Wohnhaeuser wie der hier dargestellten Typenserie 1-507 alles andere als aussichtslos ist, wie oft vermutet wird. Sie koennen im Gegenteil durchaus als komfortabler und funktionaler Wohnraum dienen. Auch die Verwendung regenerativer Energiequellen wie der Solarenergie ist unter den Bedingungen einer noerdlich gelegenen Stadt wie Sankt Petersburg realisierbar. Die durchgefuehrten Berechnungen zeigen, dass eine Sanierung der russischen Wohnbauten der ersten Periode des industriellen Bauens durchaus lohnenswert sein kann, insbesondere wenn man die Entwicklung der Energiepreise betrachtet. In seiner energieeffizientesten Form (''Passivhaus'') bringt eine Sanierung eine Reduzierung des Endenergiebedarfs von bis zu 90 % im Vergleich zum Bestandsgebaeude mit sich.

    Solar energy will surely continue to be the most important renewable energy source. Since 1985, solar cell production has doubled every five years while the per unit price decreased continuously. This trend is expected to continue. Germany made important contributions both in the construction of new solar cell production plants and in the development of new PV materials and material combinations, as well as in technology and PV plant construction. The states of Thuringia and Saxony were significant contributors. In Thuringia, two solar cell production plants were constructed, while Saxon vacuum coating technology was used in nearly all new German production plants. This workshop presented the activities in Thuringia in Saxony. Contacts were to be established between partners from industry and research, joint projects were to be initiated, and society and politicians were to be informed on the success and new chances achieved. The workshop was held on the occasion of the termination of construction and the starting of experimental production of the ANTEC Solar GmbH factory at Rudisleben. [German] Im Mix der erneuerbaren Energien spielt die Solarenergie kuenftig wohl die wichtigste Rolle. Seit 1985 verdoppelt sich die Solarzellenproduktion in jeweils fuenf Jahren, gleichzeitig sank der Preis pro Leistungseinheit kontinuierlich. Dieser Trend wird weiter anhalten.

Der Anteil Thueringens und Sachsens an dieser positiven Entwicklung ist groesser als generell vermutet.

    The energy transition in the heating sector is not a sure-fire success and it is too slow. This is alarming since the heating / cooling sector is responsible for more than half of the final energy demand. That the ''thermal change'' has accelerated hardly despite many efforts by politics, industry and research in recent years, is the reason for the scientists the FVEE institutes to examine the perspectives of renewable energy and the need to increase efficiency in the heating sector systematically. therefore FVEE-2015 Annual Meeting, is entitled ''Research for the thermal change''. The contributions of this conference proceedings present the latest research results and show ways to implement the heat change technically, economically and politically. They are dedicated to the drivers, but also the barriers of heat change. The authors report on innovative projects to provide buildings with heat from geothermal energy, biomass and solar thermal energy. Several contributions are dedicated to the application of efficient components, such as thermal insulation, thermal storage and heat pumps.

Dass die ''Waermewende'' trotz vielerlei Bemuehungen von Politik, Industrie und Forschung in den letzten Jahren kaum Fahrt aufgenommen hat, ist Anlass fuer die Wissenschaftlerinnen und Wissenschaftler der FVEE-Institute, die Perspektiven der erneuerbaren Energien und der notwendigen Effizienzsteigerung im Waermesektor systematisch zu untersuchen. Die FVEE-Jahrestagung 2015 steht deshalb unter dem Leitthema ''Forschung fuer die Waermewende''.

    Writing an abstract is a challenging skill that requires precision and care. Criteria for well-formulated abstracts and abstract guidelines for 2 types of articles (empirical studies and reviews or theoretical articles) as well as a description of the content of a structured abstract are presented. Details were gleaned from a review of the literature including the American Medical Association Manual of Style, Eighth Edition and the Publication Manual of the American Psychological Association, Fourth Edition. A good abstract is like a crystal: it is a clear, sharp synthesis that elucidates meaning for the reader.

    Reducing the noise level in the interior of vehicles is both a comfort necessity and a challenging technical task. Reliable identification of the accessories responsible for high or low engine-noise levels in the interior of cars classically requires costly, time-consuming, extensive measurement sessions. Artificial intelligence tools efficiently solve the mentioned system-identification problem, and provide a principled way of extracting the information of interest from reduced size databases.

    Buckwheat whole plant can be used for the production of biogas. Due to its short growing period, buckwheat can be integrated very variable in crop rotations. For example, buckwheat can be grown as a second crop in the summer. After the harvest of winter wheat, which is used as whole plant silage, the sowing date is around mid-June. The ingredients of buckwheat expect a good fermentability with corresponding biogas production. [German] Buchweizen-Ganzpflanzen koennen fuer die Erzeugung von Biogas genutzt werden. Durch seine kurze Vegetationsperiode laesst sich Buchweizen sehr variabel in Fruchtfolgen einbinden. Zum Beispiel kann Buchweizen als Zweitfrucht im Sommer angebaut werden. Nach der Ernte von Wintergetreide, das als Ganzpflanzensilage genutzt wird, liegt der Saattermin etwa Mitte Juni. Die Inhaltsstoffe von Buchweizen lassen eine gute Vergaerbarkeit mit einer entsprechenden Biogasproduktion erwarten.

    By a reaction with steam, bioresidues and plants can be converted into a gas consisting mainly of hydrogen, carbon monoxide and methane which can be used for electric power generation in gas engines, gas turbins and fuel cells. The conversion processes, especially the fuel cell process, are environment-friendly and efficient. For decentralized applications (i.e. for biomass volumes of 0.5 to 1 t/h), an allothermal process is recommended which is described in detail.

    Historically, German environmental policy has always been based on order policy, so Germany is lagging behind, as compared with Denmark or England, in accumulating initial experience with emissions trading as a clean air policy instrument. The Baden-Wuerttemberg Environmental Ministry therefore initiated a strategic game, in which trading of greenhouse gas emissions can be learned by Baden-Wuerttemberg's industrial organisations. The project called SET UP is presented, results are analyzed, and conclusions are drawn. [German] Da die deutsche Umweltpolitik traditionell ordnungspolitisch gepraegt ist, liegen bisher - im Unterschied zu anderen EU-Mitgliedstaaten wie Daenemark oder England - kaum praktische Erfahrungen mit dem marktwirtschaftlichen Instrument Emissionsrechthandel vor.

    Full Text Available One of the main challenges of embodied theories is accounting for meanings of abstract words. The most common explanation is that abstract words, like concrete ones, are grounded in perception and action systems. According to other explanations, abstract words, differently from concrete ones, would activate situations and introspection; alternatively, they would be represented through metaphoric mapping. However, evidence provided so far pertains to specific domains. To be able to account for abstract words in their variety we argue it is necessary to take into account not only the fact that language is grounded in the sensorimotor system, but also that language represents a linguistic-social experience. To study abstractness as a continuum we combined a concrete (C verb with both a concrete and an abstract (A noun; and an abstract verb with the same nouns previously used (grasp vs. describe a flower vs. a concept. To disambiguate between the semantic meaning and the grammatical class of the words, we focused on two syntactically different languages: German and Italian. Compatible combinations (CC, AA were processed faster than mixed ones (CA, AC. This is in line with the idea that abstract and concrete words are processed preferentially in parallel systems - abstract in the language system and concrete more in the motor system, thus costs of processing within one system are the lowest. This parallel processing takes place most probably within different anatomically predefined routes. With mixed combinations, when the concrete word preceded the abstract one (CA, participants were faster, regardless of the grammatical class and the spoken language. This is probably due to the peculiar mode of acquisition of abstract words, as they are acquired more linguistically than perceptually. Results confirm embodied theories which assign a crucial role to both perception-action and linguistic experience for abstract words.

  5. Analysis of complex networks using aggressive abstraction.

    Colbaugh, Richard; Glass, Kristin.; Willard, Gerald

    2008-10-01

    This paper presents a new methodology for analyzing complex networks in which the network of interest is first abstracted to a much simpler (but equivalent) representation, the required analysis is performed using the abstraction, and analytic conclusions are then mapped back to the original network and interpreted there. We begin by identifying a broad and important class of complex networks which admit abstractions that are simultaneously dramatically simplifying and property preserving we call these aggressive abstractions -- and which can therefore be analyzed using the proposed approach. We then introduce and develop two forms of aggressive abstraction: 1.) finite state abstraction, in which dynamical networks with uncountable state spaces are modeled using finite state systems, and 2.) onedimensional abstraction, whereby high dimensional network dynamics are captured in a meaningful way using a single scalar variable. In each case, the property preserving nature of the abstraction process is rigorously established and efficient algorithms are presented for computing the abstraction. The considerable potential of the proposed approach to complex networks analysis is illustrated through case studies involving vulnerability analysis of technological networks and predictive analysis for social processes.

    Full Text Available Minimalism in architecture contains the idea of the minimum as a leading creative tend to be considered and interpreted in working through phenomena of empathy and abstraction. In the Western culture, the root of this idea is found in empathy of Wilhelm Worringer and abstraction of Kasimir Malevich. In his dissertation, 'Abstraction and Empathy' Worringer presented his thesis on the psychology of style through which he explained the two opposing basic forms: abstraction and empathy. His conclusion on empathy as a psychological basis of observation expression is significant due to the verbal congruence with contemporary minimalist expression. His intuition was enhenced furthermore by figure of Malevich. Abstraction, as an expression of inner unfettered inspiration, has played a crucial role in the development of modern art and architecture of the twentieth century. Abstraction, which is one of the basic methods of learning in psychology (separating relevant from irrelevant features, Carl Jung is used to discover ideas. Minimalism in architecture emphasizes the level of abstraction to which the individual functions are reduced. Different types of abstraction are present: in the form as well as function of the basic elements: walls and windows. The case study is an example of Sou Fujimoto who is unequivocal in its commitment to the autonomy of abstract conceptualization of architecture.

    Abstraction is the key when learning behavioral models of realistic systems. Hence, in most practical applications where automata learning is used to construct models of software components, researchers manually define abstractions which, depending on the history, map a large set of concrete events...... to a small set of abstract events that can be handled by automata learning tools. In this article, we show how such abstractions can be constructed fully automatically for a restricted class of extended finite state machines in which one can test for equality of data parameters, but no operations on data...

    Lead has always been an important metal in plain bearing technology. Completely lead-free solutions for high-end engine applications are still not considered to be technically achievable. Therefore, the European End of Life Directive (2000/53/EC), which took effect on 1 July 2003, lists copper-based lead/bronze bearings as an exception. The bearing group of Federal-Mogul has now announced its exit from the lead industry and addresses the issue layer by layer. A recently introduced adaptive bearing offers a lead-free overplate for high-performance internal combustion engine applications. This new bearing changes its technical characteristics during the running-in phase. (orig.) [German] Blei war schon immer eine wichtige Komponente in der Gleitlagertechnik.

While earlier projects focused on the technical side, EFAS is the first to present a systematic analysis, presentation and evaluation of the parameters influencing driving support systems. With the aid of a systemic analysis, the key influencing factors are defined and analyzed, and three scenarios are developed which take account of user-oriented, organizational, operational, technical, infrastructural and legal aspects. The scenarios are evaluated with the aid of driving and traffic simulations in the fields of humans, organization and technology, and actions are recommended on this basis for driving support systems in cargo transport.

  15. Hydrogen abstraction reactions by amide electron adducts

    1982-01-01

    Electron reactions with a number of peptide model compounds (amides and N-acetylamino acids) in aqueous glasses at low temperature have been investigated using ESR spectroscopy. The radicals produced by electron attachment to amides, RC(OD)NDR', are found to act as hydrogen abstracting agents. For example, the propionamide electron adduct is found to abstract from its parent propionamide. Electron adducts of other amides investigated show similar behavior except for acetamide electron adduct which does not abstract from its parent compound, but does abstract from other amides. The tendency toward abstraction for amide electron adducts are compared to electron adducts of several carboxylic acids, ketones, aldehydes and esters. The comparison suggests the hydrogen abstraction tendency of the various deuterated electron adducts (DEAs) to be in the following order: aldehyde DEA > acid DEA = approximately ester DEA > ketone DEA > amide DEA. In basic glasses the hydrogen abstraction ability of the amide electron adducts is maintained until the concentration of base is increased sufficiently to convert the DEA to its anionic form, RC(O - )ND 2 . In this form the hydrogen abstracting ability of the radical is greatly diminished. Similar results were found for the ester and carboxylic acid DEA's tested. (author)

Es behandelt die Frage, ob ein Umweltzeichen fuer kleine BHKW-Module gerechtfertigt ist, und welche Anforderungen diese im Vergabefall erfuellen sollten. Im Rahmen der Untersuchung wurde zunaechst eine umfassende Marktanalyse durchgefuehrt, um daraus die Anlagen zu identifizieren, die fuer ein Umweltzeichen in Frage kommen. Im Hauptteil der Studie ging es um die vertiefende Analyse der Umweltrelevanz der ausgewaehlten Anlagen. Hierzu wurde eine Herstellerbefragung durchgefuehrt und ausgeaehlte BHKW anhand eines Systemvergleiches mit Gas- und Oelheizkesseln verglichen. Auf der Basis dieser Analyse wurden Anforderungskataloge fuer Gas- und Diesel-BHKW-Module abgeleitet, die in einem Fachgespraech in einer breiten Runde von Experten und Herstellern vorgestellt und diskutiert wurden. Aus der Studie und dem Fachgespraech konnte ein deutliches Votum fuer ein Umweltzeichen fuer die untersuchten BHWK-Module abgeleitet werden. Die vorgeschlagenen Vergabegrundlagen umfassen Anforderungen an Richtlinienkonformitaet, rationelle Energienutzung (Elektrischer und Gesamtwirkungsgrad bei Nennlast und Teillast, Angabe des Hilfsstrombedarfes), Emissionswerte von CO, NO{sub x}, Staub und organischen Stoffen, Schallemissionen, Angebot von Wartungsvertraegen, Ruecknahmeverpflichtung sowie Anforderungen an die Bedienungsanleitung.

    corresponding a low influence of the lateral boundary conditions. Overall, REMO has proved to be a useful tool for a better understanding of the processes in the Arctic and the North Atlantic. Further adjustment of the parameterizations seems to be necessary. Other components of the climate system have to be considered to successfully describe the complex feedbacks and processes of the climate subsystems. (orig.) [German] Die Arktis und der subpolare Nordatlantik bilden mit ihren komplexen Mechanismen und Rueckkopplungen eine wichtige Komponente unseres Klimasystems. Aufgrund der geringen Beobachtungsdichte und der niedrigen Aufloesung globaler Klimamodelle, bietet sich der Einsatz hoeher aufloesender regionaler Klimamodelle an. Das hier verwendete regionale Klimamodell (REMO) basiert auf dem frueheren Wettervorhersagemodell EM des Deutschen Wetterdienstes (DWD) und wurde am Max-Planck-Institut fuer Meteorologie (MPIfM) in Hamburg weiterentwickelt. Fuer die Simulation subskaliger Prozesse stehen zwei Saetze physikalischer Parametrisierungen zur Verfuegung - die urspruenglich verwendete DWD-Physik und die ECHAM4-Physik des MPIfM. Der dynamische Teil ist in beiden Faellen identisch. REMO wird zunaechst an das neue Untersuchungsgebiet angepasst. Die neue Konfiguration beruecksichtigt bei einer horizontalen Aufloesung von 0.5 x 0.5 und 145 x 121 Glitterpunkten die gesamte Arktis und den Nordatlantik bis etwa 40 N. Mit DWD- und ECHAM4-Physik im Vorhersage- und Klima-Mode werden unterschiedliche Zeitraeume simuliert. Als Antriebsdaten werden die NCEP/NCAR-Reanalysen mit einer zeitlichen Aufloesung von 6 Stunden verwendet. Da REMO bisher nur in gemaessigtem Klima eingesetzt wurde, steht der Test des Modells unter den extremen Bedingungen der hohen Breiten im Vordergrund. Beim Vergleich mit Schiffsbeobachtungen aus der Labrador-See liegt REMO deutlich dichter an den Messungen als die Antriebsdaten. Unrealistisch hohe Feuchten in den Reanalysen sind vermutlich die Ursache erhoehter

    As a prerequisite for MR-guidance of interventional procedures, instruments have to be well depicted in the MR image without obscuring or distorting the underlying anatomy. For non-vascular interventions the imaging speed has to be in the range of seconds while control of vascular interventions requires real time imaging speed. The imaging contrast has to be maintained as well as a high spatial resolution. Furthermore, sufficient patient access has to be provided by the MR scanner. Neither an ideal magnet nor the optimal single sequence are available to fulfill the above-mentioned criteria. The type of sequence - gradient echo versus spin echo - together with changing of the echo time and phase encording direction will ensure an appropriate size of the artifact and thereby of the appearance of the instrument in the MR image. The feasibility of non-vascular MR-guided interventions has been proved at field strengths ranging from 0.064 T to 1.5 T. Bone biopsies, soft tissue biopsies, drainages, and control of interstitial thermo- and cryotherapy have been reported. For vascular interventions, different real time MR strategies are currently under investigation. The development of dedicated catheters and guide wires has enabled MR-guided dilatations, stenting, placement of vena cava filters, and TIPS procedures. Considering the fast progress being made in this field, there can be no question that interventional MRI will become a well-accepted clinical tool offering potential advantages such as excellent soft tissue contrast, multiplanar imaging, flow measurements, high resolution imaging of vessel walls, and lack of ionizing radiation. (orig.) [German] Zur Durchfuehrung MR-gesteuerter Interventionen muessen interventionelle Instrumente gut sichtbar, aber ohne stoerende Artefakte darstellbar sein.

Die Ganzkoerper-low-dose-CT und Ganzkoerper-MRT ermoeglichen eine Darstellung sowohl des mineralisierten Knochens als auch des Knochenmarks mit einer hoeheren Sensitivitaet, hoeherem Patientenkomfort und im Falle der MRT ohne Strahlenbelastung. Nach den Ergebnissen der Literatur sind Schnittbildverfahren dem Roentgenskelettstatus signifikant ueberlegen, wobei die Ganzkoerper-MRT fuer den Nachweis insbesondere eines diffusen Knochenmarkbefalls signifikant besser ist als die Ganzkoerper-CT. Praktisch jeder osteodestruktive Herd ist in der MRT sichtbar. Allerdings ist fuer die Beurteilung der Osteodestruktion selbst wiederum eine CT erforderlich. Die Sensitivitaeten von PET/CT und MRT sind vergleichbar. Wie bereits in einigen Zentren insbesondere in Deutschland umgesetzt, sollten bei Verfuegbarkeit das Ganzkoerper-MRT und das Ganzkoerper-CT den konventionellen Roentgenskelettstatus ersetzen. Bei Erstdiagnose bzw. Verdacht auf eine monoklonale Gammopathie unklarer Signifikanz (MGUS), ''smoldering multiple myeloma'' und symptomatisches multiples Myelom sollten sowohl eine Ganzkoerper-MRT als auch eine Ganzkoerper-CT durchgefuehrt werden. Bei asymptomatischem Myelom oder MGUS waere die Ganzkoerper-MRT bis zur Detektion des ersten umschriebenen Myelomherdes ausreichend. Beim symptomatischen Myelom mit Knochenlaesionen sollten in der Regel die Ganzkoerper-CT und fuer spezielle Fragestellungen die MRT eingesetzt werden. (orig.)

    2009-05-22

    Arbeit beschaeftigt sich mit einem drei- zu zweiphasigen Matrixumrichter zur Speisung von kontaktlosen Energieuebertragungssystemen. Aufbauend auf einer Darlegung relevanter Untersuchungen zur Thematik werden zunaechst moegliche Resonanzanordnungen fuer kontaktlose Energieuebertragungssysteme untersucht. Die Betrachtung wichtiger elektrischer Parameter zeigt neben den Unterschieden der einzelnen Anordnungen auch, dass fuer eine auf den speisenden Umrichter fokussierte Untersuchung eine einfache Modellierung der drei untersuchten Resonanzanordnungen mit Hilfe eines Reihenschwingkreises moeglich ist. Als Konsequenz ergibt sich die Schlussfolgerung, dass sich die erzielten Ergebnisse auch fuer den Matrixumrichter mit anderen serienresonanten Lasten anwenden lassen. Der zweite Teil der Arbeit ist der Untersuchung des Matrixumrichters gewidmet. Basierend auf einer theoretischen Beschreibung wird die Kombination von hochfrequenten Steuerverfahren - wie z.B. der Blocktaktung - und niederfrequenten Pulsmustern zur Stellung des Oberschwingungsgehalts der Netzstroeme vorgestellt. Die Aehnlichkeit des Umrichters zu einem konventionellen Wechselrichter in H-Brueckenschaltung ermoeglicht anschliessend eine Betrachtung der Kommutierung und die Ableitung notwendiger Schaltzustaende. Diese sind dadurch gekennzeichnet, dass zu jedem Zeitpunkt genau eine bidirektionale Verbindung vom Eingangssystem zu jeder Ausgangsphase besteht. Die Funktionsweise der Kommutierung wie auch des gesamten Umrichters wird in einem ersten Schritt simulativ belegt. Dabei wird auch das dynamische Schaltverhalten der Leistungshalbleiter beruecksichtigt. Anschliessend werden an einem Laboraufbau aufgenommene Messergebnisse vorgestellt und mit den theoretischen Ergebnissen verglichen. Der Laboraufbau besteht aus dem Leistungsteil des Matrixumrichters mit Eingangsfiltern und modularen Gate-Treibern, einem DSP/FPGA-Steuerungssystem und einem kontaktlosen Energieuebertragungssystem mit sekundaerseitigem Gleichrichter

  11. MeGARA: Menu-based Game Abstraction and Abstraction Refinement of Markov Automata

    Directory of Open Access Journals (Sweden)

    Bettina Braitling

    2014-06-01

    Full Text Available Markov automata combine continuous time, probabilistic transitions, and nondeterminism in a single model. They represent an important and powerful way to model a wide range of complex real-life systems. However, such models tend to be large and difficult to handle, making abstraction and abstraction refinement necessary. In this paper we present an abstraction and abstraction refinement technique for Markov automata, based on the game-based and menu-based abstraction of probabilistic automata. First experiments show that a significant reduction in size is possible using abstraction.

    Abstraction is a fundamental mechanism underlying both human and artificial perception, representation of knowledge, reasoning and learning. This mechanism plays a crucial role in many disciplines, notably Computer Programming, Natural and Artificial Vision, Complex Systems, Artificial Intelligence and Machine Learning, Art, and Cognitive Sciences. This book first provides the reader with an overview of the notions of abstraction proposed in various disciplines by comparing both commonalities and differences.  After discussing the characterizing properties of abstraction, a formal model, the K

The abstracts were gathered in early 1978 and represent the status of the various programs as of that date. It is not suggested that this is a comprehensive list of all the work that is going on in the development of particle beam diagnostics, but it does provide a representative view of the work in this field. For example, no abstracts were received from the U.S.S.R. even though they have considerable activity in particle beam diagnostics

    Abstractions are used in model checking to tackle problems like state space explosion or modeling of IO. The application of these abstractions in real software development processes, however, lacks engineering support. This is one reason why model checking is not widely used in practice yet...... and testing is still state of the art in falsification. We show how user-defined abstractions can be integrated into a Java PathFinder setting with tools like AspectJ or Javassist and discuss implications of remaining weaknesses of these tools. We believe that a principled engineering approach to designing...

    We formalize a string analysis within abstract interpretation framework. The abstraction of strings is given as a conjunction of predicates that describes the common configuration changes on the reference pushdown automaton while processing the strings. We also present a family of pushdown automata called ɛ bounded pushdown automata. This family covers all context-free languages, and by using this family of pushdown automata, we can prevent abstract values from becoming infinite conjunctions and guarantee that the operations required in the analyzer are computable.

    Abstracts afford an opportunity to report data at professional meetings and, when published, in the literature. Accordingly, they should be prepared with great care. When writing an abstract, anticipate questions the reviewer will ask when judging it and provide complete answers. The presentation of an abstract should follow similar thought processes. State why a problem or question is important, how you addressed it, what you found, and how your findings can be applied to the issue at hand. Slides and text should provide coordinated visual and auditory input, respectively, to ensure complete comprehension.

    We bridge the gap between functional evaluators and abstract machines for the λ-calculus, using closure conversion, transformation into continuation-passing style, and defunctionalization.We illustrate this approach by deriving Krivine's abstract machine from an ordinary call-by-name evaluator...... and by deriving an ordinary call-by-value evaluator from Felleisen et al.'s CEK machine. The first derivation is strikingly simpler than what can be found in the literature. The second one is new. Together, they show that Krivine's abstract machine and the CEK machine correspond to the call-by-name and call......-by-value facets of an ordinary evaluator for the λ-calculus.We then reveal the denotational content of Hannan and Miller's CLS machine and of Landin's SECD machine. We formally compare the corresponding evaluators and we illustrate some degrees of freedom in the design spaces of evaluators and of abstract...

  11. Abstracting audit data for lightweight intrusion detection

    KAUST Repository

    Wang, Wei

    2010-01-01

    High speed of processing massive audit data is crucial for an anomaly Intrusion Detection System (IDS) to achieve real-time performance during the detection. Abstracting audit data is a potential solution to improve the efficiency of data processing. In this work, we propose two strategies of data abstraction in order to build a lightweight detection model. The first strategy is exemplar extraction and the second is attribute abstraction. Two clustering algorithms, Affinity Propagation (AP) as well as traditional k-means, are employed to extract the exemplars, and Principal Component Analysis (PCA) is employed to abstract important attributes (a.k.a. features) from the audit data. Real HTTP traffic data collected in our institute as well as KDD 1999 data are used to validate the two strategies of data abstraction. The extensive test results show that the process of exemplar extraction significantly improves the detection efficiency and has a better detection performance than PCA in data abstraction. © 2010 Springer-Verlag.

The initial material is pure silicon as used in the production of electronic chips. Bayer Solar GmbH are producers of monocrystalline and multicrystalline silicon wafers. By the end of 1999, their two works at Uerdingen and Freiberg had a total capacity of about 36 MWp, i.e. about 25% of the world demand. [German] Im Beitrag wird der Werdegang vom Silicium bis zum photovoltaischen System kurz dargestellt, wobei, bedingt durch eine teilweise Arbeitsteilung, die Si-Wafer und Zellen als Zwischenstufen auftreten. Die Bayer Solar GmbH hat sich dabei bis heute auf die Herstellung von mono- und multikristallinen Siliciumscheiben konzentriert, wobei Werke in Uerdingen und Freiberg Ende 1999 eine Gesamtkapazitaet von etwa 36 MWp bereit halten, was ca. 25% des weltweiten Bedarfs entspricht. Der Weg vom Silicium zum Wafer umfasst das Schmelzen und Kristallisieren, die Saeulen- und Scheibenherstellung, eine sorgfaeltige Scheibenreinigung und anschliessende Qualitaetskontrolle jeder einzelnen Siliciumscheibe. Ausgangsmaterial ist ein hochreines Silicium, wie es aehnlich auch fuer die Chipherstellung in der Elektronik verwendet wird. (orig.)

    Processes in which a heat pump cycle is driven by thermal energy may be defined as heat transformation processes. The technical realization of this type of processes in general is based on sorption techniques. Depending on the temperature level of the utilized heat these technologies may be used for either cooling or heating of buildings. The paper presents state-of-the-art technologies and new developments. It comprises solar cooling of buildings, utilization of environmental energy sources (earth, air) by thermal driven heat pumps and seasonal storage of solar thermal energy by means of sorption processes. (orig.) [Deutsch] Unter Waermetransformationsverfahren werden im allgemeinen Verfahren verstanden, in denen ein Waermepumpenprozess mit thermischer Energie angetrieben wird. Die technische Realisierung dieser Verfahren erfolgt ueberwiegend mit Hilfe von Sorptionsvorgaengen. Abhaengig vom Temperaturniveau des Nutzwaermestroms koennen solche Verfahren im Gebaeudebereich fuer die Kuehlung oder Heizung eingesetzt werden. Im Beitrag werden der Stand der Technik sowie neue Entwicklungen vorgestellt. Im einzelnen umfasst der Beitrag die solare Kuehlung von Gebaeuden, die Nutzung von Umweltenergie (Erdreich, Luft) mittels thermisch angetriebener Waermepumpen sowie die saisonale Speicherung von Solarenergie ueber Sorptionsprozesse.

    Highly automated production and logistic systems require mechatronic drives. The book describes how industrial production and logistics work, and how the appropriate drive systems should be designed. The function of the mechanical and electronic elements of a drive system is described, including the required software, and the fundamentals of dimensioning are gone into. The authors also discuss engineering, reliability and important life cycle aspects. Applications in material flow and handling technology, in continuous and clocked production lines and finishing processes are presented in twelve sections offering different drive solutions for the motor, current inverter and software, transmission system and mechanical elements. The specific requirements and functionalities of these twelve solutions are presented. The focus is on energy conversion with controlled electric drive systems. (orig.) [German] Hochautomatisierte Produktions- und Logistikanlagen benoetigen mechatronische Antriebsloesungen. Dieses Buch beschreibt, wie die industrielle Fertigung und Logistik arbeitet und wie die hierzu erforderlichen Antriebsloesungen aufgebaut sind. Es wird die Funktionsweise der mechanischen und der elektronischen Elemente eines Antriebssystems einschliesslich der Software beschrieben und ihre Dimensionierungsgrundlagen behandelt. Die Autoren gehen darueber hinaus auf das Engineering, die Zuverlaessigkeit und auf wichtige Aspekte des Lebenszyklus ein. Die Vielzahl der Anwendungen in der Materialfluss- und der Handhabungstechnik, in kontinuierlichen und getakteten Produktionslinien sowie fuer Bearbeitungsprozesse wird in insgesamt zwoelf Antriebsloesungen eingeteilt. Diese umfassen den Motor, den Umrichter mit seiner Software, das Getriebe sowie mechanische Antriebselemente. Es werden die spezifischen Anforderungen und die Funktionalitaet dieser zwoelf Loesungen dargestellt. Dabei konzentrieren sich die Autoren auf die Energieumsetzung mit geregelten elektrischen

    There are various financing and organisation models in use at German waste treatment plants. These models have an influence on capital costs as well as on operating costs. The great variety of existing models, which is not only found in theory but also in practice, is a sure indication that there is no universal solution at present but that models always have to be adapted to the current conditions governing the plant in question (e.g., tax law amendments). In view of the great complexity of this subject the following deliberations will be restricted to only the best-known types of financing model. [Deutsch] Fuer den Betrieb von Abfallbehandlungsanlagen gibt es bundesweit verschiedene Organisations- und Finanzierungsmodelle. Diese Modelle haben Auswirkungen auf die Kapitalkosten und die Betriebskosten. Die Vielfalt der nicht nur theoretisch moeglichen, sondern auch der in der Praxis existierenden Modelle ist mit Sicherheit ein Hinweis, dass derzeit keine universelle Loesung moeglich ist, sondern diese immer den aktuellen und spezifischen Verhaeltnissen (z.B. Steuerrechtsaenderung u.a.) angepasst werden muss. Auf Grund der Komplexibilitaet beschraenken sich die nachfolgenden Ausfuehrungen ausschliesslich auf die bekanntesten Formen der Finanzierungsmodelle. (orig./SR)

    One lesson to be learned from completely deregulated markets is that the national governments of the countries, in designing the national energy pricing policies, will be strongly led by macroeconomic interests, and will see to it that the transmission charges will be levelled down in the course of deregulation. Hence regional electric utilities have to get prepared for a drop in sales in their core business, as compared to pre-deregulation times. The strategy adopted by the Pfalzwerke regional utility is explained in this article. The innovative management concept proved to achieve significant cost savings permitting sustainable compatibility of the utility in the market. (orig./CB) [German] Beispiele aus liberalisierten Vorreitermaerkten zeigen, dass der Staat ein makrooekonomisches Interesse daran hat, durch ordnungspolitische Eingriffe die Preise fuer Durchleitungsentgelte drastisch zu senken. So muessen sich die regionalen Versorgungsunternehmen zukuenftig auf massive Umsatzeinbussen in dem bislang monopolgeschuetzten Kerngeschaeft vorbereiten. Die Pfalzwerke versprechen sich durch ihr innovatives Organisationskonzept mit signifikanten Kosteneinsparungen eine nachhaltige Sicherung ihrer Wettbewerbsposition im Markt. (orig./CB)

    Deutsche Bahn is presently endeavouring to further improve the interaction between the overhead wire and the current collectors on its locomotives and trainsets. The major factors behind this initiative are cost, quality and noise prevention. The outcome is the development of a completely new type of current collector for high-speed operation even on conventional track. Prototypes have meanwhile undergone practical trials on the 200 km/h line from Augsburg to Donauwoerth. The new current collector is a single-arm pantograph jointly developed by DB and Bombardier Transportation. (orig.)

    Surface water, and drinking water obtained from surface water, should be largely free of organic compounds. This applies particularly to substances that are not or poorly degradable in the environment. Pollution of surface water with poorly degradable toxic substances - especially from industrial applications - can be avoided or at least largely reduced by means of specially adapted biological waste water cleaning techniques. The compound ethylene diamine tetraacetate (EDTA), which has multiple technical applications and is used in large amounts, demonstrates that even contaminants considered to be unsuitable for biological treatment can be eliminated from waste water by means of certain biological processes employing specially enriched bacterial cultures. (orig.) [Deutsch] Oberflaechengewaesser und daraus gewonnenes Trinkwasser sollen moeglichst frei von organischen Verbindungen sein. Dies gilt insbesondere fuer Substanzen, die in der Umwelt nicht oder nur sehr langsam abbaubar sind. Eine Belastung von Oberflaechengewaessern mit schwer abbaubaren `Problemstoffen` - insbesondere aus industriellen Anwendungsbereichen - kann unter anderem mit Hilfe speziell angepasster Verfahren zur biologischen Abwasserreinigung vermieden beziehungsweise weitestgehend reduziert werden. Am Beispiel der technisch sehr vielfaeltig und in grossen Mengen eingesetzten Verbindung EDTA (Ethylendiamintetraacetat) laesst sich erkennen, dass durch bestimmte bioverfahrenstechnische Massnahmen mit Hilfe speziell angereicherter Bakterienkulturen auch als `biologieunfaehig` eingestufte Problemstoffe aus Abwaessern eliminiert werden koennen.

    Magnetic resonance imaging (MRI) of the liver has become an essential tool in the radiological diagnostics of both focal and diffuse diseases of the liver and is subject to constant change due to technological progress. Recently, important improvements could be achieved by innovations regarding MR hardware, sequences and postprocessing methods. The diagnostic spectrum of MRI could be broadened particularly due to new examination sequences, while at the same time scanning time could be shortened and image quality has been improved. The aim of this article is to explain both the technological background and the clinical application of recent MR sequence developments and to present the scope of a modern MRI protocol for the liver. (orig.) [German] Die Magnetresonanztomographie (MRT) der Leber ist in der radiologischen Diagnostik fokaler und diffuser Lebererkrankungen fest etabliert und untersteht einem steten Wandel durch den fortwaehrenden technischen Fortschritt.

Insbesondere auf dem Gebiet der Untersuchungssequenzen kam es zu Entwicklungen, die das diagnostische Spektrum der MRT erweiterten, zu einer Verkuerzung der Scanzeit fuehrten und zu einer Verbesserung der Bildqualitaet beitrugen. Gegenstand dieses Artikels ist es, den technischen Hintergrund und die klinische Anwendung neuerer Sequenztechniken zu erklaeren und so die Moeglichkeiten und den Umfang eines modernen MRT-Untersuchungsprotokolls fuer die Leber darzustellen.

    Hahn-Meitner-Institut fuer Kernforschung Berlin (HMI) is one of the twelve large research centers of the Federal Republic of Germany; like the other centers, it has to present a combined research programme and budget (programme budget) every year. In these programme budgets, as in the medium-term financial planning in the federal budget, planning for the current year is combined with a medium-term plan for the three next years. For the year 1981, the budget of HMI includes a total expenditure of about DM 85 million, DM 71.2 million of which are direct R + D expenditures. This R + D programme is carried by 396 of the total staff of 705. Research is done in the following fields (approximate figures): Heavy ion physics DM 23.0 million. Radiation- and photochemistry DM 11.4 million. Solid state research DM 20.9 million. Nuclear chemistry DM 8.9 million. Data processing/electronics DM 7.0 million. (orig./UA) [de

    Due to the insufficient transfer of knowledge from projects, construction company organisations do not use the potentials for their competitive advantage. In this paper a knowledge management process will be presented for the identification, classification and allocation of knowledge integrated in the controlling process of enterprises, which is bounded to civil works occurrence. The presented occurrence orientated knowledge process model was developed at the Swiss Federal Institute of Technology in Zurich. This is not a holistic knowledge management concept for a construction company; it is focused on the process and the relevant participants and users. (orig.) [German] Durch den ungenuegenden Wissenstransfer von Projektwissen werden von Bauunternehmungen potentielle Synergien zur Verbesserung der Wettbewerbsfaehigkeit nicht ausreichend genutzt. In diesem Beitrag wird ein Wissensmanagementprozess dargestellt, der an der ETH Zuerich entwickelt wurde, welcher ereignisorientiertes Wissen in Bauunternehmungen identifiziert, hinsichtlich der Zielpersonen klassifiziert und dieses Wissen zur Nutzung in Projekten bereitstellt. Fuer die Identifikation werden Instrumente des Controlling herangezogen. Dieses Wissensmanagementkonzept soll einen kontinuierlichen Verbesserungsprozess auf der Basis des ereignisorientierten Wissens einleiten, um aus positiven sowie negativen Ereignissen in den Bauprojekten zu lernen und so zu einer lernenden Organisation zu gelangen.

    Integration of abstractly similar relations during analogical reasoning was investigated using functional magnetic resonance imaging. Activation elicited by an analogical reasoning task that required both complex working memory and integration of abstractly similar relations was compared to activation elicited by a non-analogical task that required complex working memory in the absence of abstract relational integration. A left-sided region of the frontal pole of the brain (BA 9/10) was selectively active for the abstract relational integration component of analogical reasoning. Analogical reasoning also engaged a left-sided network of parieto-frontal regions. Activity in this network during analogical reasoning is hypothesized to reflect categorical alignment of individual component terms that make up analogies. This parieto-frontal network was also engaged by the complex control task, which involved explicit categorization, but not by a simpler control task, which did not involve categorization. We hypothesize that frontopolar cortex mediates abstract relational integration in complex reasoning while parieto-frontal regions mediate working memory processes, including manipulation of terms for the purpose of categorical alignment, that facilitate this integration.

Die ebenfalls notwendige CE-Zertifizierung der Ultrahochfeldscanner (7-8 T) in Europa ist fuer zukuenftige Geraete zu erwarten. Bestehende Installationen werden nicht automatisch zertifiziert, sondern behalten ihren experimentellen Status. Die aktuelle Erweiterung der IEC 60601-2-33 fuehrt eine neue Zusatzoption, die sog. ''fixed parameter option'' (FPO) ein. Diese Option kann zusaetzlich zu den etablierten Betriebsarten geschaltet werden und definiert eine fixe Geraetekonstellation und bestimmte Parameter des Energieoutputs von MR-Scannern, die zukuenftig die Untersuchungen von Implantatpatienten vereinfachen soll.

    When the 4 August deadline for submitting Fall Meeting abstracts passed, AGU had received more than 20,000 abstracts, a record-breaking number. The submission process had an unexpected by-product: It inspired some scientists to write haiku on Twitter. (Haiku is a form of Japanese poetry typically having three lines, the first with five syllables, the second with seven, and the third with five.) The following are examples of the haiku tweets, with the hashtag #AGU11AbstractHaiku. (For those who want to keep updated about the Fall Meeting on Twitter, the hashtag is #AGU11.)

    Since abstract algebra is so important to the study of advanced mathematics, it is critical that students have a firm grasp of its principles and underlying theories before moving on to further study. To accomplish this, they require a concise, accessible, user-friendly textbook that is both challenging and stimulating. A First Graduate Course in Abstract Algebra is just such a textbook.Divided into two sections, this book covers both the standard topics (groups, modules, rings, and vector spaces) associated with abstract algebra and more advanced topics such as Galois fields, noncommutative rings, group extensions, and Abelian groups. The author includes review material where needed instead of in a single chapter, giving convenient access with minimal page turning. He also provides ample examples, exercises, and problem sets to reinforce the material. This book illustrates the theory of finitely generated modules over principal ideal domains, discusses tensor products, and demonstrates the development of det...

    For the further investigation of the large scale transport and chemical transformation of air pollutants with atmospheric models reliable emission data with a high temporal, spatial and species resolution are required for Europe. Within the GENEMIS project methods and models have been developed to generate such data, starting from annual emission data of the CORINAIR and LOTOS inventories. The main objective of converting annual emission data into reliable hourly values has been reached on the basis of numerous socio-economical, meteorological and technical indicator data. The models which were developed within this framework have been used to generate european emission inventories for different base years and selected episods. The analysis of the results showed significant spatial and large temporal variations of the emissions. It has been shown that former simplifying assumptions concerning the temporal behaviour of emissions were not sufficient to describe real situations. The emission data calculated within GENEMIS have been used directly as an input for air quality modeling purposes. (orig.)

    A liquid nitrogen pump with contactless superconducting magnetic bearings was to be developed on the basis of an available motor with superconducting bearings. Contactless superconducting magnetic bearings require practically no servicing. A high demand for pumps for cryogenic liquids is expected with the impending use of hydrogen as an energy source. The pumping of liquid nitrogen was demonstrated successfully with the new test aggregate. The maximum pumped volume was 17 l/min at a lift of 0.5 m and 6 l/min at a lift of 1 m. In all, 15 hours of operation were registered in the superconducting state of the bearing, which included 2 hours of uninterrupted pump operation. The higher speed range for which magnetic bearings are optimally suited was not reached. Operation at higher frequencies was impossible either because of stronger resonance amplituees or because the power system was too weak. [German] Ziel des Vorhabens war die Entwicklung einer Pumpe fuer fluessigen Stickstoff mit beruehrungslosen supraleitenden Magnetlagern auf der Basis eines vorhandenen supraleitend gelagerten Motors. Die beruehrungslose supraleitende Magnetlager sind praktisch wartungsfrei. Ein Bedarf an Pumpen fuer kryogene Fluessigkeiten entsteht insbesondere durch den in naher Zukunft zu erwartenden Einsatz von Wasserstoff als Energietraeger. Mit dem entworfenen Aggregat wurde das Pumpen von Fluessigstickstoff erfolgreich demonstriert. Der Foerderstrom betrug bei 0,5m Foerderhoehe maximal 17 l/min; beim 1m Foerderhoehe wurden maximal 6 l/min gemessen. Es wurden insgesamt ca. 15 Betriebsstunden in supraleitenden Zustand des Lagers, darunter 2 Stunden ununterbrochener Pumpbetrieb registriert. Der hoehere Drehzahlbereich, fuer den das Magnetlager eigentlich paedestiniert ist, konnte nicht erreicht werden. Ein Betrieb bei hoeheren (Ist-)Frequenzen war nicht moeglich, entweder durch staerkere Resonanzausschlaege oder durch einen zu schwachen Antrieb. (orig.)

    Small villages, solitary farms, alpine dairy farms etc. usually have no connection to the supply and disposal systems of municipal or public utilities. Since mountain huts in particular are often situated in ecologically sensitive areas (e.g. the Alps), their operation requires an efficient use of water and energy. Present-day power supply concepts for stand-alone systems are mostly based on solar cells with a battery storage and a diesel generator for peak load management and periods of bad weather. If wastewater discharge and waste disposal are also taken into account it is necessary to take a new all-inclusive ecological view of the system, since the energy demand of the disposal systems can double that of the entire site. This calls for new, comprehensive supply and disposal systems which permit reliable, energy self-sufficient operation. This paper presents the individual components of an energy self-sufficient supply and disposal system for remote locations comprising energy and water supply, wastewater treatment and organic waste treatment.

Da besonders Berghuetten (z.B. in den Alpen) ausserdem haeufig in oekologisch sehr sensiblen Gebieten liegen, ist es notwendig, die Ressourcen Wasser und Energie rationell zu verwenden. Die derzeitigen Energiekonzepte fuer die Stromversorgung von Inselsystemen basieren meist auf der Verwendung von Solarzellen mit Batteriespeicher und einem Dieselaggregat, um Spitzenbelastungen und Schlechtwetterperioden zu ueberbruecken. Die Einbeziehung der Wasser- und Abfallentsorgung erfordert neue gesamtoekologische Betrachtungsweisen, da der Energiebedarf fuer die Entsorgung den Energieverbrauch der gesamten Inselsysteme verdoppeln kann. Hier sind neue und unfassende Ver- und Entsorgungskonzepte gefragt, die einen gesicherten autarken Betrieb ermoeglichen. Im vorliegenden

    OpenAIRE

    Hermenegildo, Manuel V.; Albert Albiol, Elvira; López García, Pedro; Puebla Sánchez, Alvaro Germán

    2005-01-01

    Proof-Carrying Code (PCC) is a general approach to mobile code safety in which the code supplier augments the program with a certifícate (or proof). The intended benefit is that the program consumer can locally validate the certifícate w.r.t. the "untrusted" program by means of a certifícate checker—a process which should be much simpler, eíñcient, and automatic than generating the original proof. Abstraction Carrying Code (ACC) is an enabling technology for PCC in which an abstract mod...

  14. Abstraction of man-made shapes

    KAUST Repository

    Mehra, Ravish

    2009-01-01

    Man-made objects are ubiquitous in the real world and in virtual environments. While such objects can be very detailed, capturing every small feature, they are often identified and characterized by a small set of defining curves. Compact, abstracted shape descriptions based on such curves are often visually more appealing than the original models, which can appear to be visually cluttered. We introduce a novel algorithm for abstracting three-dimensional geometric models using characteristic curves or contours as building blocks for the abstraction. Our method robustly handles models with poor connectivity, including the extreme cases of polygon soups, common in models of man-made objects taken from online repositories. In our algorithm, we use a two-step procedure that first approximates the input model using a manifold, closed envelope surface and then extracts from it a hierarchical abstraction curve network along with suitable normal information. The constructed curve networks form a compact, yet powerful, representation for the input shapes, retaining their key shape characteristics while discarding minor details and irregularities. © 2009 ACM.

  3. Embodied cognition, abstract concepts, and body manipulation

    Directory of Open Access Journals (Sweden)

    Katinka eDijkstra

    2014-08-01

    Full Text Available Current approaches on cognition hold that concrete concepts are grounded in concrete experiences. There is no consensus, however, as to whether this is equally true for abstract concepts. In this review we discuss how the body might be involved in understanding abstract concepts through metaphor activation. Substantial research has been conducted on the activation of common orientational metaphors with bodily manipulations, such as ‘power is up’ and ‘more is up’ representations. We will focus on the political metaphor that has a more complex association between the concept and the concrete domain. However, the outcomes of studies on this political metaphor have not always been consistent, possibly because the experimental manipulation was not implicit enough. The inclusion of new technological devices in this area of research, such as the Wii Balance Board, seems promising in order to assess the groundedness of abstract conceptual spatial metaphors in an implicit manner. This may aid further research to effectively demonstrate the interrelatedness between the body and more abstract representations.

    Science.gov (United States)

    Latif, Syukriyanto; Suwardoyo, Untung; Aldrin Wihelmus Sanadi, Edwin

    2018-03-01

    This study aims to classify abstract content based on the use of the highest number of words in an abstract content of the English language journals. This research uses a system of text mining technology that extracts text data to search information from a set of documents. Abstract content of 120 data downloaded at www.computer.org. Data grouping consists of three categories: DM (Data Mining), ITS (Intelligent Transport System) and MM (Multimedia). Systems built using naive bayes algorithms to classify abstract journals and feature selection processes using term weighting to give weight to each word. Dimensional reduction techniques to reduce the dimensions of word counts rarely appear in each document based on dimensional reduction test parameters of 10% -90% of 5.344 words. The performance of the classification system is tested by using the Confusion Matrix based on comparative test data and test data. The results showed that the best classification results were obtained during the 75% training data test and 25% test data from the total data. Accuracy rates for categories of DM, ITS and MM were 100%, 100%, 86%. respectively with dimension reduction parameters of 30% and the value of learning rate between 0.1-0.5.

    As an essential part of forest environmental monitoring, the Forest State Report 2013 shows how environmental factors influence the development of our forests. In addition to the annual survey of the crown state, intensive land surveys were established by the country, which provide extensive results over a long period. Data on the status and growth of the tree, the nutrient cycle, the material intake, soil status, soil vegetation and meteorology, ie the dynamics of environmental changes, are collected. Fortunately, the Forest State Report in 2013 shows that the state of the forests in Baden-Wuerttemberg has slightly improved compared to the previous year. This means that the trend towards the improvement of forest conditions continues after the extreme drought year 2003. This improvement is attributable to the spring weather which is favorable to the forest as well as to a generally low occurrence of harmful insects. [German] Als wesentlicher Teil des forstlichen Umweltmonitorings zeigt der Waldzustandsbericht 2013, wie Umweltfaktoren die Entwicklung unserer Waelder beeinflussen. Ergaenzend zur jaehrlichen Erhebung des Kronenzustandes wurden durch das Land Intensivmessflaechen eingerichtet, die umfangreiche Ergebnisse ueber einen langen Zeitraum liefern. Dort werden Daten zu Baumzustand und -wachstum, Naehrstoffkreislauf, Stoffeintrag, Bodenzustand, Bodenvegetation sowie Meteorologie, also die Dynamik der Umweltveraenderungen, erhoben. Erfreulicherweise zeigt der Waldzustandsbericht 2013, dass sich der Zustand der Waelder in Baden-Wuerttemberg gegenueber dem Vorjahr leicht verbessert hat. Damit setzt sich der Trend zur Verbesserung des Waldzustandes nach dem extremen Trockenjahr 2003 weiter fort. Diese Verbesserungstendenz laesst sich auf die fuer den Wald guenstige Fruehjahrswitterung sowie auf ein allgemein geringes Vorkommen an Schadinsekten zurueckfuehren.

    This contribution investigates thermokinetic parameters of bimolecular gas-phase reactions involving the amine (NH 2 ) radical and a large number of saturated and unsaturated hydrocarbons. These reactions play an important role in combustion and pyrolysis of nitrogen-rich fuels, most notably biomass. Computations performed at the CBS-QB3 level and based on the conventional transition-state theory yield potential-energy surfaces and reaction rate constants, accounting for tunnelling effects and the presence of hindered rotors. In an analogy to other H abstraction systems, we demonstrate only a small influence of variational effects on the rate constants for selected reaction. The studied reactions cover the abstraction of hydrogen atoms by the NH 2 radical from the C-H bonds in C 1 -C 4 species, and four C 5 hydrocarbons of 2-methylbutane, 2-methyl-1-butene, 3-methyl-1-butene, 3-methyl-2-butene, and 3-methyl-1-butyne. For the abstraction of H from methane, in the temperature windows 300-500 and 1600-2000 K, the calculated reaction rate constants concur with the available experimental measurements, i.e., k calculated /k experimetal = 0.3-2.5 and 1.1-1.4, and the previous theoretical estimates. Abstraction of H atom from ethane attains the ratio of k calculated /k experimetal equal to 0.10-1.2 and 1.3-1.5 over the temperature windows of available experimental measurements, i.e., 300-900 K and 1500-2000 K, respectively. For the remaining alkanes (propane and n-butane), the average k experimental /k calculated ratio remains 2.6 and 1.3 over the temperature range of experimental data. Also, comparing the calculated standard enthalpy of reaction (Δ r H° 298 ) with the available experimental measurements for alkanes, we found the mean unsigned error of computations as 3.7 kJ mol -1 . This agreement provides an accuracy benchmark of our methodology, affording the estimation of the unreported kinetic parameters for H abstractions from alkenes and alkynes. On the basis of

  16. Abstraction of Drift-Scale Coupled Processes

    International Nuclear Information System (INIS)

    2000-01-01

    This Analysis/Model Report (AMR) describes an abstraction, for the performance assessment total system model, of the near-field host rock water chemistry and gas-phase composition. It also provides an abstracted process model analysis of potentially important differences in the thermal hydrologic (TH) variables used to describe the performance of a geologic repository obtained from models that include fully coupled reactive transport with thermal hydrology and those that include thermal hydrology alone. Specifically, the motivation of the process-level model comparison between fully coupled thermal-hydrologic-chemical (THC) and thermal-hydrologic-only (TH-only) is to provide the necessary justification as to why the in-drift thermodynamic environment and the near-field host rock percolation flux, the essential TH variables used to describe the performance of a geologic repository, can be obtained using a TH-only model and applied directly into a TSPA abstraction without recourse to a fully coupled reactive transport model. Abstraction as used in the context of this AMR refers to an extraction of essential data or information from the process-level model. The abstraction analysis reproduces and bounds the results of the underlying detailed process-level model. The primary purpose of this AMR is to abstract the results of the fully-coupled, THC model (CRWMS M andO 2000a) for effects on water and gas-phase composition adjacent to the drift wall (in the near-field host rock). It is assumed that drift wall fracture water and gas compositions may enter the emplacement drift before, during, and after the heating period. The heating period includes both the preclosure, in which the repository drifts are ventilated, and the postclosure periods, with backfill and drip shield emplacement at the time of repository closure. Although the preclosure period (50 years) is included in the process models, the postclosure performance assessment starts at the end of this initial period

    High-efficiency natural gas burner technology is regarded by some Member States of the EU as an important option to achieve energy conservation and greenhouse gas abatement standards. This why application of this technology for water heating or space heating in the residential sector as well as, to some part, in small-sized business, is promoted by a variety of schemes offering financial incentives. Such schemes are offered by gas utilities, serving the purposes of customer services, or demand-side management (DSM), or market expansion and environmental policy. The last two aspects also apply to schemes offered by public funds, i.e. governmental, Land, or local government programmes. The programmes differ in approaches and objectives and in requirements of performance. (orig./CB) [Deutsch] Die Brennwerttechnik fuer Erdgasheizungen wird in einigen Laendern der Europaeischen Union als wichtige Option zur Energieeinsparung und zur Minderung der CO{sub 2}-Emissionen angesehen. Die Marktdurchdringung von Brennwerttechnik fuer die Raumwaerme- und Warmwasserbereitstellung im Haushaltssektor wie auch teilweise fuer Gewerbe und Kleinverbrauch wird daher vielfach durch finanzielle Anreize zum Kauf entsprechender Anlagen vorangetrieben. Solche Foerderprogramme werden von Unternehmen der Gasversorgung unter den Gesichtspunkten Kundenservice, Demand-Side Management (DSM), Marktausweitung und Klimaschutz aufgelegt, letzteres gilt auch fuer Programme durch die oeffentliche Hand, z.B. das CO{sub 2}-Minderungsprogramm der Bundesregierung oder Programme von Laendern und Kommunen. Dabei unterscheiden sich die Programme in Konzeption und Abwicklung. (orig./HS)

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

    Double layer capacitors are the system of choice whenever a large number of cycles and high capacity are required. They have the advantages of high cyclic strength, high capacity, freedom of servicing, insensitivity to high temperatures and long life. Drawbacks are low energy density, high self-discharge and high cost.Applications in water pumps, pathfinders and roller blind control systems were investigated. [German] Mit den Ergebnissen steht ein detailliertes Wissen ueber den weltweiten Entwicklungsstand und die physikalischen Eigenschaften von Doppelschichtkondensatoren zur Verfuegung. Ihre Eigenschaften wurden in Bezug auf moegliche photovoltaische Anwendungen hin analysiert. Anwendungsfehlder ergeben sich vorzugsweise dann, wenn hohe Zyklenzahl und Leistungsfaehigkeit gefordert werden. Die Vorteile des neuen Energiespeichers sind seine hohe Zyklenfestigkeit und Leistungsfaehigkeit, seine Wartungsfreiheit, Temperaturunempfindlichkeit und lange Lebensdauer. Ihnen stehen die Nachteile einer geringen Energiedichte, hohen Selbstentladung und hoher Kosten gegenueber. Eine deutliche Steigerung der Gesamteffizienz von photovoltaischen Versorgungseinheiten beim Einsatz von Doppelschichtkondensatoren ergeben energetische Simulationen unterschiedlicher Systeme. Fuer ausgewaehlte photovoltaisch versorgte Anwendungen konnte die Einsatzfaehigkeit von Doppelschichtkondensatoren in Feldtests erprobt und nachgewiesen werden. Wasserpumpensysteme, Pathfinders und eine Rolladensteuerung fuer ein Fenster wurden getestet. Der Einsatz von Doppelschichtkondensatoren zur weiteren Verbreitung photovoltaischer Anwendungen ist bereits heute fuer spezielle Anwendungen sinnvoll und wirtschaftlich. Mit weiter fallenden Preisen fuer die Kondensatoren und der Entwicklung von Kondensatorsystemen mit hoeheren Spannungen werden weitere Anwendungsfelder hinzukommen. Die Basis zur Entwicklung der notwendigen Systemtechnik und ihrer Demonstration in Feldversuchen ist durch die Ergebnisse des

    The submitted feasibility study furnished the proof that a 'two-way vehicle' (duotrans) for the application on road and rail for the local traffic is suitable and innovative alignment enabled. On the basis of sample applications the management was checked up to the local classification of the drive change places. Selected applications were evaluated regarding their economy. As an obstacle the rail use fees were put out. Outgoing from the obtained result conclusions for resuming steps were suggested. As summary it can be stated that a number of applications, sufficient for the system application, exists. (orig.) [German] Die vorgelegte Machbarkeitsstudie hat den Nachweis erbracht, dass ein Zweiwegefahrzeug (Duotrans) fuer den Einsatz auf Strasse und Schiene fuer den OePNV geeignet ist und innovative Linienfuehrungen ermoeglicht. An Hand von Anwendungsbeispielen wurde die Betriebsdurchfuehrung bis hin zur standoertlichen Einordnung der Fahrwegwechselstellen geprueft. Ausgewaehlte Anwendungsfaelle wurden hinsichtlich ihrer Wirtschaftlichkeit bewertet. Als ein Hemmnis wurden die Schienennutzungsgebuehren herausgestellt. Ausgehend vom erzielten Ergebnis wurden Schlussfolgerungen fuer weiterfuehrende Schritte vorgeschlagen. Als Resuemee kann festgestellt werden, dass eine fuer den Systemeinsatz ausreichende Anzahl von Anwendungsfaellen existiert. (orig.)

    With the ongoing application of new materials (Al, Mg, Plastic) as an alternative to steel in light-weight body in white construction it is necessary to develop and use other joining and fixing technologies than spot welding, bolt-and nut-welding. These new technologies for example are mechanical joining technology as clinching and self-pierce-riveting, blind-riveting and special elements to fix other parts as blind-rivets and self-piercing nuts and bolts. These products are mainly used for metal materials and mixed structures. To fix other parts to plastic-parts direct-screwing or the after-moulding-technology with metal or plastic inserts is used. (orig.) [German] Mit der verstaerkten Anwendung von weiteren Werkstoffen (Al, Mg, Kunststoffe) als Stahl im Automobilbau ist die Notwendigkeit erwachsen, alternative Fuege- und Befestigungstechniken zum Punktschweissen, Bolzen- und Mutternschweissen zu entwickeln. Hierzu gehoeren die mechanischen Fuegetechniken wie Stanznieten, Clinchen, Blindnieten sowie die sogenannten Funktionselemente zum Befestigen von Anbauteilen, wie Blind- und Stanznietmuttern und -bolzen. Diese Verfahren werden ueberwiegend fuer metallische Werkstoffe oder bei Mischbauweise angewandt. Fuer die Befestigung an Kunststoffbauteilen wird die Direktverschraubung oder die after-moulding-technik (AMTEC {sup registered}) verwendet. (orig.)

    within a distance of 1.5 km to a planned well field. In the river valley the interaction between groundwater and surface water is strongly affected by low permeable sediments. These sediments reduce the direct discharge to the river and have a large impact on the functioning and presence of the rich fen......Quantifying the effects of groundwater abstraction on fen ecosystems located in discharge areas can be complicated. The water level in fens is close to the terrain surface most of the year and it is controlled by a relatively constant groundwater exfiltration. It is difficult to measure...... the exfiltration fluxes and thus water level data is typically used to evaluate if the ecosystem is affected. The paper presents collected data and analysis from a case study, where the hydrological effect of groundwater abstraction on rich fens and springs in a Danish river valley has been studied. The natural...

  9. Abstract Level Parallelization of Finite Difference Methods

    Directory of Open Access Journals (Sweden)

    Edwin Vollebregt

    1997-01-01

    Full Text Available A formalism is proposed for describing finite difference calculations in an abstract way. The formalism consists of index sets and stencils, for characterizing the structure of sets of data items and interactions between data items (“neighbouring relations”. The formalism provides a means for lifting programming to a more abstract level. This simplifies the tasks of performance analysis and verification of correctness, and opens the way for automaticcode generation. The notation is particularly useful in parallelization, for the systematic construction of parallel programs in a process/channel programming paradigm (e.g., message passing. This is important because message passing, unfortunately, still is the only approach that leads to acceptable performance for many more unstructured or irregular problems on parallel computers that have non-uniform memory access times. It will be shown that the use of index sets and stencils greatly simplifies the determination of which data must be exchanged between different computing processes.

  10. Old Romanian pluralized mass and abstract nouns

    2017-09-01

    Full Text Available The analysis of a rich old Romanian corpus shows that the ‘pluralization’ of mass and abstract nouns is extremely frequent in old Romanian. The semantic effects of pluralization are similar for mass and abstract nouns, consisting in the creation of denotative and/or connotative semantic variants. Of the plural endings, –uri is specialized for the pluralization of mass nouns in Daco-Romanian. The evolution of the ending –uri illustrates the specific process by which a grammatical (plural morpheme is converted into a lexical morpheme (the so-called ‘lexical plurals’. ‘Lexical plurals’ have isolated occurrences in other Romance languages, but they have not reached the spread and regularity they display in Romanian.

    2004-01-01

    The purpose of the saturated zone (SZ) flow and transport model abstraction task is to provide radionuclide-transport simulation results for use in the total system performance assessment (TSPA) for license application (LA) calculations. This task includes assessment of uncertainty in parameters that pertain to both groundwater flow and radionuclide transport in the models used for this purpose. This model report documents the following: (1) The SZ transport abstraction model, which consists of a set of radionuclide breakthrough curves at the accessible environment for use in the TSPA-LA simulations of radionuclide releases into the biosphere. These radionuclide breakthrough curves contain information on radionuclide-transport times through the SZ. (2) The SZ one-dimensional (I-D) transport model, which is incorporated in the TSPA-LA model to simulate the transport, decay, and ingrowth of radionuclide decay chains in the SZ. (3) The analysis of uncertainty in groundwater-flow and radionuclide-transport input parameters for the SZ transport abstraction model and the SZ 1-D transport model. (4) The analysis of the background concentration of alpha-emitting species in the groundwater of the SZ

    Full Text Available The unusual edition of Elements of Euclid released for publishing in 1847 by Oliver Byrne offers the occasion to suggest a few elements for discussion on the uniqueness of the ‘representation’ of geometric-mathematical thinking—and more in general of the abstract thinking—enshrined in its ‘nature of a pure imaginative vision able to connect the intelligible with the tangible’. The purpose is, thus, a reasoning on images and communicative artefacts, that, when articulated, provide different variations of the idea of ‘transcription’ of complex theoretical structures from one language (that of abstract logic to another (that of sensory experience, with a view to facilitate, ease and make more accurate the noetic process. Images able over time to facilitate the understanding of complex and abstract theoretical principles—since able to show them in an extremely concrete way, ad oculos,—and which at some points could reveal the horizons of art interpretation to inscrutable and figurative meaningless formulas.

  2. The abstract representations in speech processing.

    Cutler, Anne

    2008-11-01

    Speech processing by human listeners derives meaning from acoustic input via intermediate steps involving abstract representations of what has been heard. Recent results from several lines of research are here brought together to shed light on the nature and role of these representations. In spoken-word recognition, representations of phonological form and of conceptual content are dissociable. This follows from the independence of patterns of priming for a word's form and its meaning. The nature of the phonological-form representations is determined not only by acoustic-phonetic input but also by other sources of information, including metalinguistic knowledge. This follows from evidence that listeners can store two forms as different without showing any evidence of being able to detect the difference in question when they listen to speech. The lexical representations are in turn separate from prelexical representations, which are also abstract in nature. This follows from evidence that perceptual learning about speaker-specific phoneme realization, induced on the basis of a few words, generalizes across the whole lexicon to inform the recognition of all words containing the same phoneme. The efficiency of human speech processing has its basis in the rapid execution of operations over abstract representations.

  3. EIA data index: an abstract journal

    International Nuclear Information System (INIS)

    1980-12-01

    The individual tables, graphs, and formatted data presented in the statistical publications of the Energy Information Administration (EIA) are abstracted and indexed. Included are a complete subject index and a report number listing for all EIA publications as well as complete ordering information for these publications. The abstracts of the tables and graphs are arranged by broad subject categories (e.g., coal, petroleum, natural gas, energy analysis and modeling) with further division occurring by subcategories (e.g., reserves, drilling and production, processing). Included here are those publications and their statistical contents which were released by the EIA from its formation in October 1977 through approximately the first half of 1980. Updates will be on a semiannual basis. The EIA Data Index is a companion volume to the EIA Publications Directory: A User's Guide (DOE/EIA-0149), which provides abstracts and indexes to all EIA publications at the document level. Both of these publications are generated from the Federal Energy Data Index (FEDEX) data base which has been developed by the EIA in cooperation with the Technical Information Center of the US Department of Energy

    2001-11-01

    The ADS Abstract Service contains over 2.3 million references in four databases: Astronomy/Astrophysics/Planetary Sciences, Instrumentation, Physics/Geophysics, and Preprints. We provide abstracts and articles free to the astronomical community for all major and many smaller astronomy journals, PhD theses, conference proceedings, and technical reports. These four databases can be queried either separately of jointly. The ADS also has scanned 1.3 million pages in 180,000 articles in the ADS Article Service. This literature archive contains all major Astronomy journals and many smaller journals, as well as conference proceedings, including the abstract books from all the LPSCs back to volume 2. A new feature gives our users the ability to see list of articles that were also read by the readers of a given article. This is a powerful tool to find out what current articles are relevant in a particular field of study. We have recently expanded the citation and reference query capabilities. It allows our users to select papers for which they want to see references or citations and then retrieve these citations/references. Another new capability is the ability to sort a list of articles by their citation count. As usual, users should be reminded that the citations in ADS are incomplete because we do not obtain reference lists from all publishers. In addition, we cannot match all references (e.g. in press, private communications, author errors, some conference papers, etc.). Anyone using the citations for analysis of publishing records should keep this in mind. More work on expanding the citation and reference features is planned over the next year.

  10. Knowledge Abstraction in Chinese Chess Endgame Databases

    Science.gov (United States)

    Chen, Bo-Nian; Liu, Pangfeng; Hsu, Shun-Chin; Hsu, Tsan-Sheng

    Retrograde analysis is a well known approach to construct endgame databases. However, the size of the endgame databases are too large to be loaded into the main memory of a computer during tournaments. In this paper, a novel knowledge abstraction strategy is proposed to compress endgame databases. The goal is to obtain succinct knowledge for practical endgames. A specialized goal-oriented search method is described and applied on the important endgame KRKNMM. The method of combining a search algorithm with a small size of knowledge is used to handle endgame positions up to a limited depth, but with a high degree of correctness.

    Michael Poulshock

    2017-06-01

    Full Text Available A theoretical model is presented which provides a way to simulate, at a very abstract level, power struggles in the social world. In the model, agents can benefit or harm each other, to varying degrees and with differing levels of influence. The agents interact over time, using the power they have to try to get more of it, while being constrained in their strategic choices by social inertia. The outcomes of the model are probabilistic. More research is needed to determine whether the model has any empirical validity.

  15. Software Security - The Dangers of Abstraction

    Science.gov (United States)

    Gollmann, Dieter

    Software insecurity can be explained as a potpourri of hacking methods, ranging from the familiar, e.g. buffer overruns, to the exotic, e.g. code insertion with Chinese characters. From such an angle software security would just be a collection of specific countermeasures. We will observe a common principle that can guide a structured presentation of software security and give guidance for future research directions: There exists a discrepancy between the abstract programming concepts used by software developers and their concrete implementation on the given execution platform. In support of this thesis, five case studies will be discussed, viz characters, integers, variables, atomic transactions, and double linked lists.

    The annual forest status report 2014 shows that the persistently high burdens have not fundamentally improved the health of the forests. In addition to significant improvements in soil conditions, which can be traced back to successful forest calcifications, climate change with its various impacts is a lasting burden on the forests. Unfortunately, the forest situation has deteriorated considerably compared to the previous year. With 42 per cent damaged trees, the third highest value has been reached since the start of the recordings about 3 years ago. This means that the medium-term trend towards the improvement of the forest state unfortunately does not continue. This is clearly evident in the crown condition as an important indicator of the health of the trees. The average needle / leaf loss of the trees has increased by 3.7 percentage points to 25.8 percent. The share of undamaged forest areas has fallen by nine percentage points to just 24 percent. These changes can be attributed to the very dry spring weather, the presence of harmful insects and a strong fruit formation. [German] Der jaehrliche Waldzustandsbericht 2014 zeigt, dass durch die unveraendert hohen Belastungen der Gesundheitszustand der Waelder sich nicht grundsaetzlich gebessert hat. Neben deutlichen Verbesserungen im Bodenzustand, die auf erfolgreiche Waldkalkungen zurueck zu fuehren sind, stellt insbesondere der Klimawandel mit seinen verschiedenen Auswirkungen eine dauerhafte Belastung der Waelder dar. Leider hat sich der Waldzustand gegenueber dem Vorjahr deutlich verschlechtert. Mit 42 Prozent geschaedigter Baeume wird der dritthoechste Wert seit Beginn der Aufnahmen vor rund 3 Jahren erreicht. Damit setzt sich der mittelfristige Trend zur Verbesserung des Waldzustandes leider nicht weiter fort. Beim Kronenzustand als wichtigem Indikator fuer den Gesundheitszustand der Baeume zeigt sich dies deutlich. Der mittlere Nadel-/Blattverlust der Baeume hat sich um 3,7 Prozentpunkte auf 25,8 Prozent

  10. DSNF AND OTHER WASTE FORM DEGRADATION ABSTRACTION

    International Nuclear Information System (INIS)

    Thornton, T.A.

    2000-01-01

    The purpose of this analysis/model report (AMR) is to select and/or abstract conservative degradation models for DOE-(US. Department of Energy) owned spent nuclear fuel (DSNF) and the immobilized ceramic plutonium (Pu) disposition waste forms for application in the proposed monitored geologic repository (MGR) postclosure Total System Performance Assessment (TSPA). Application of the degradation models abstracted herein for purposes other than TSPA should take into consideration the fact that they are, in general, very conservative. Using these models, the forward reaction rate for the mobilization of radionuclides, as solutes or colloids, away from the waste fondwater interface by contact with repository groundwater can then be calculated. This forward reaction rate generally consists of the dissolution reaction at the surface of spent nuclear fuel (SNF) in contact with water, but the degradation models, in some cases, may also include and account for the physical disintegration of the SNF matrix. The models do not, however, account for retardation, precipitation, or inhibition of the migration of the mobilized radionuclides in the engineered barrier system (EBS). These models are based on the assumption that all components of the DSNF waste form are released congruently with the degradation of the matrix

    This preparatory study, ``Shaft barriers for underground waste repositories in abandoned salt mines``, was to demonstrate the current scientific and technological know-how based on a comprehensive analysis of the barrier design concepts or established structures intended to serve as barriers in abandoned shafts of potash or rock salt mines. Taking as a basis the current regulatory regime and the available know-how on barrier systems in underground waste repositories taken into account so far in plan approval and licensing procedures, as well as the state of the art, concepts are developed as technical guides and models of barrier systems for mine shafts. The required research work for the various components of a shaft barrier is shown, particularly relating to aspects such as materials suitability and technical realisation. Immediate demand for research activities is shown with regard to the available potentials of mathematic and numeric geotechnical and hydrogeologic calculation models required in order to give proof of the long-term workability of shaft barriers. The authors are of the opinion that the following activities are required in order to meet the research demand quantified: (1) Laboratory and bench-scale experiments for determination of the efficiency of various sealing materials and backfilling materials, and (2) an in-situ, large-scale experiment in order to demonstrate the suitability of low-consolidation shotter columns, or constructional technologies. The laboratory work can be done in the facilities of the GSF research mine of Asse, the Freiburg Mining Academy, and the Institut fuer Gebirgsmechanik in Leipzig, and the benchmark experiments also at the Asse site in the research mine. The Kali und Salz Beteiligungs AG is prepared to offer its mine Salzdetfurth II as a site for the large-scale experiment. (orig.)

Ist keine oder nur eine eingeschraenkte Ueberwachung vorhanden, sind die moeglichen Folgen eventuell bisher unbekannter Schadensmechanismen durch erweiterte und ggf. vagabundierende WKP-Massnahmen zu ueberpruefen. Fuer die Auswahl von Pruefbereichen und die Festlegung von Pruefintervallen ist die Verwendung der Auslegungsanalysen, in denen konservativ spezifizierte Belastungen und Lastfallhaeufigkeiten (fuer Betriebs- und Stoerfaelle) beruecksichtigt wurden, nicht geeignet. Es ist vielmehr von den `Ist-Beanspruchungen` aus dem bisherigen Betrieb in Verbindung mit der Kenntnis ueber die vorhandene `Istqualitaet` aus der Herstellung und der bisherigen Betriebszeit auszugehen. Die vorhandenen Unterlagen sind entsprechend aufzubereiten, so dass eine Grundlage fuer die Neubewertung der bisherigen ZfP-Massnahmen gegeben ist. (orig./MM)

As a result, the report details the main elements and conditions that are necessary for campaigns that cover all types of renewable energies, such campaigns are supported in principal by all stakeholder groups. (orig.) [German] (a) Die Kampagne 'Solar - na klar.' unterstuetzt seit 1999 eine verstaerkte Verbreitung von solarthermischen Anlagen durch vielfaeltige Oeffentlichkeitsarbeit und Dienstleistungen. Die Evaluation der Kampagne kam bezueglich der externen Wirkungen zu ueberwiegend positiven Ergebnissen: Die zentralen Zielgruppen, Handwerker und der Ein-/Zweifamilienhausbesitzer, wurden durch die Kampagne gut erreicht und mit gutem Informationsmaterial angesprochen. Darueber hinaus schaetzte ca. ein Viertel der Haushalte, die eine solarthermische Anlage installierten, den Einfluss der Kampagne eher hoch ein. Allerdings vermissten die Haushalte zum Teil weiterfuehrende Informationen. Auch die befragten Handwerker aeusserten eine relativ grosse Zufriedenheit mit der Kampagne. Sie nutzten die bereitgestellten Informationsmaterialien der Kampagne jedoch nur sehr selten. Die Evaluation der internen Grundlagen und Prozesse fuehrt zu ambivalenten Ergebnissen: Beispielsweise ist es der Kampagne auf der einen Seite gelungen, eine breite und heterogene Traegerschaft zu gewinnen und flexibel auf aeussere Anforderungen zu reagieren. Auf der anderen Seite stellten sich Probleme in der Steuerung und im Konfliktmanagement ein. Hierzu trugen u.a. eine nicht ausreichend integrierte Projektplanung sowie strukturelle Unterschiede zwischen den Partnern bei. Die Evaluation muendet in der zentralen Empfehlung, die Kampagne in modififizierter Form fortzusetzen. Verbesserungsmoeglichkeiten sehen die Evaluatoren u.a. in der verstaerkten Einbindung regionaler Aktvitaeten.

    The aim of the research project is the development of a technique for reasonably priced mass- production of large area holographic focussers for photo-electrics. The holograms up to 1 m{sup 2} in size simultaneously act as spectrum dispersing and focussing optical elements, which focus the sunlight in discrete bands on spectrally matched solar cells. The three most important characteristics of the holographic focussers are the refractive efficiency, the spectrum bandwidth and the central working wavelength. The optimum values of the parameters conditional on the variation of the layer thickness and the mean refractive index via the aperture of the hologram and on the ability of the layer to make large modulations of the refractive index possible. The mass-production of large format holographic lenses demands precise coating of the carrier substrate of the hologram copies with dichromate gelatine and is done with the aid of a scanning copying process. (orig.) [Deutsch] Ziel des Forschungsvorhabens ist die Entwicklung einer Technololgie fuer die preiswerte serielle Herstellung von grossflaechigen holographischen Konzentratoren fuer die Photovoltaik. Die bis zu 1 m{sup 2} grossen Hologramme wirken gleichzeitig als spektral dispergierende und fokussierende optische Elemente, die das Sonnenlicht in diskreten Baendern auf spektral angepasste Solarzellen konzentrieren. Die drei wichtigsten Charakteristiken der holographischen Konzentratoren sind die Beugungseffizienz, die spektrale Bandbreite und die zentrale Arbeitswellenlaenge. Die optimalen Werte dieser Parameter sind eindeutig durch die Variation der Schichtdicke und des mittleren Brechungsindexes ueber die Apertur des Hologramms sowie durch die Faehigkeit der Schicht, grosse Brechnungsindexmodulation zu ermoeglichen, bedingt. Die serielle Fertigung der grossformatigen holographischen Linsen verlangt eine praezise Beschichtung der Traegersubstrate der Hologrammkopien mit Dichromat-Gelatine und erfolgt mit Hilfe eines

    As directed by a written development plan (CRWMS M and O 1999a), Task 1, an overall conceptualization of the physical and chemical environment (P/CE) in the emplacement drift is documented in this Analysis/Model Report (AMR). Included are the physical components of the engineered barrier system (EBS). The intended use of this descriptive conceptualization is to assist the Performance Assessment Department (PAD) in modeling the physical and chemical environment within a repository drift. It is also intended to assist PAD in providing a more integrated and complete in-drift geochemical model abstraction and to answer the key technical issues raised in the U.S. Nuclear Regulatory Commission (NRC) Issue Resolution Status Report (IRSR) for the Evolution of the Near-Field Environment (NFE) Revision 2 (NRC 1999). EBS-related features, events, and processes (FEPs) have been assembled and discussed in ''EBS FEPs/Degradation Modes Abstraction'' (CRWMS M and O 2000a). Reference AMRs listed in Section 6 address FEPs that have not been screened out. This conceptualization does not directly address those FEPs. Additional tasks described in the written development plan are recommended for future work in Section 7.3. To achieve the stated purpose, the scope of this document includes: (1) the role of in-drift physical and chemical environments in the Total System Performance Assessment (TSPA) (Section 6.1); (2) the configuration of engineered components (features) and critical locations in drifts (Sections 6.2.1 and 6.3, portions taken from EBS Radionuclide Transport Abstraction (CRWMS M and O 2000b)); (3) overview and critical locations of processes that can affect P/CE (Section 6.3); (4) couplings and relationships among features and processes in the drifts (Section 6.4); and (5) identities and uses of parameters transmitted to TSPA by some of the reference AMRs (Section 6.5). This AMR originally considered a design with backfill, and is now being updated (REV 00 ICN1) to address

    Polycyclic aromatic hydrocarbons (PAHs) are omnipresent in the interstellar medium (ISM) and also in carbonaceous meteorites (CM) such as Murchison. However, the basic reaction routes leading to the formation of even the simplest PAH-naphthalene (C 10 H 8 )-via the hydrogen-abstraction/acetylene-addition (HACA) mechanism still remain ambiguous. Here, by revealing the uncharted fundamental chemistry of the styrenyl (C 8 H 7 ) and the ortho-vinylphenyl radicals (C 8 H 7 )-key transient species of the HACA mechanism-with acetylene (C 2 H 2 ), we provide the first solid experimental evidence on the facile formation of naphthalene in a simulated combustion environment validating the previously postulated HACA mechanism for these two radicals. This study highlights, at the molecular level spanning combustion and astrochemistry, the importance of the HACA mechanism to the formation of the prototype PAH naphthalene. © 2016 Wiley-VCH Verlag GmbH & Co.

    Total System Performance Assessments (TSPAs) are likely to be one of the most significant parts of making safety cases for the continued development and licensing of geologic repositories for the disposal of spent fuel and HLW. Thus, it is critical that the TSPA model capture the 'essence' of the physical processes relevant to demonstrating the appropriate regulation is met. But how much detail about the physical processes must be modeled and understood before there is enough confidence that the appropriate essence has been captured? In this summary the level of model abstraction that is required is discussed. Approaches for subsystem and total system performance analyses are outlined, and the role of best estimate models is examined. It is concluded that a conservative approach for repository performance, based on limited amount of field and laboratory data, can provide sufficient confidence for a regulatory decision

    The report contains abstracts of 132 case studies of bioremediation technology applied to hazardous waste clean-up. It was prepared to compile bioremediation studies in a variety of locations and treating diverse contaminants, most of which were previously undocumented. All data are based on vendor-supplied information and there was no opportunity to independently confirm its accuracy. These 132 case studies, from 10 different biotechnology companies, provide users with reference information about on-going and/or completed field applications and studies. About two-thirds of the cases were at full-scale clean-up level with the remainder at pilot or laboratory scale. In 74 percent of the cases, soil was at least one of the media treated. Soil alone accounts for 46 percent of the cases. Petroleum-related wastes account for the largest contaminant with 82 cases. Thirty-one states are represented in the case studies

    In order to carry out a study of wafer patterning, equipment was developed for safe handling of silicon wafers from 2 to 8 inch diameters. The unit can be safely and relatively straightforwardly operated by personnel, using a wide range of etchants and electrochemical deposition processes. The design also allows the effects of electrolyte flowrate in the process chamber confronting the silicon wafer, to be assessed. These features were utilised to study copper and nickel electrodeposition to pattern the wafer surface. (orig.)

    The investigation focused on controlled hydrological storage system. Existing operating schedules and new control options were analyzed, classified and generalized in order to obtain a standardized terminology and operating concept. This generalized approach will do away with the need for system-specific analyses and models for every single new system. [German] Der Schwerpunkt dieser Arbeit ist der wasserwirtschaftliche Betrieb von regelbaren Speichersystemen und ihre Simulation. Dabei bestand das Ziel darin, bestehende Betriebsplaene und neue praktikable Steuerungsmoeglichkeiten zu analysieren, zu klassifizieren und so zu generalisieren, dass eine einheitliche Terminologie und Konzeption zum Betrieb von Speichern entstand. Dieses Konzept erlaubt, in Verbindung mit den Prinzipien aus der Modellierung von Flussgebieten, verschieden strukturierte Speichersysteme mit unterschiedlichsten Steuerungsvorschriften abzubilden. Damit erhaelt man den Vorteil einer generalisierten Anwendung im Gegensatz zu einer fuer den speziellen Fall konzipierten und nicht uebertragbaren Einzelloesung. Als Folge davon entfaellt das systemspezifische, je nach Aufgabenstellung neu zu entwerfende und zu programmierende Einzelmodell. (orig.)

    Vascular pathologies are rare causes of an acute abdomen. If the cause is a vascular disease a rapid diagnosis is desired as vascular pathologies are associated with high mortality. A differentiation must be made between arterial and venous diseases. An occlusion of the superior mesenteric artery is the most common reason for acute mesenteric ischemia but intra-abdominal arterial bleeding is also of great importance. Venous pathologies include thrombotic occlusion of the portal vein, the mesenteric vein and the vena cava. Multi-detector computed tomography (MDCT) is predestined for the diagnostics of vascular diseases of the abdomen. Using multiphasic contrast protocols enables reliable imaging of the arterial and venous vessel tree and detection of disorders with high sensitivity and specificity. Although conventional angiography has been almost completely replaced by MDCT as a diagnostic tool, it is still of high importance for minimally invasive interventions, for example in the management of gastrointestinal bleeding. (orig.) [German] Vaskulaere Pathologien sind seltene Ursachen fuer den klinischen Zustand eines akuten Abdomens.

    The mission of the NABIR program is to provide the fundamental science that will serve as the basis for the development of cost-effective bioremediation and long-term stewardship of radionuclides and metals in the subsurface at DOE sites. The focus of the program is on strategies leading to long-term immobilization of contaminants in situ to reduce the risk to humans and the environment. Contaminants of special interest are uranium, technetium, plutonium, chromium, and mercury. The focus of the NABIR program is on the bioremediation of these contaminants in the subsurface below the root zone, including both vadose and saturated zones. The program consists of four interrelated Science Elements (Biotransformation, Community Dynamics/Microbial Ecology, Biomolecular Science and Engineering, and Biogeochemistry). The program also has a cross-cutting Assessment Element that supports development of innovative approaches and technologies to support the science elements. An element called Bioremediation and its Societal Implications and Concerns (BASIC) addresses potential societal issues of implementing NABIR scientific findings. The material presented at this year's workshop focuses on approximately 60 research projects funded in FY 2000-2003 by the Environmental Remediation Sciences Division in DOE's Office of Biological and Environmental Research (BER) in the Office of Science. Abstracts of NABIR research projects are provided in this book.

  11. Abstract User Interfaces for Mobile Processes

    Science.gov (United States)

    Zaplata, Sonja; Vilenica, Ante; Bade, Dirk; Kunze, Christian P.

    An important focus of recent business process management systems is on the distributed, self-contained and even disconnected execution of processes involving mobile devices. Such an execution context leads to the class of mobile processes which are able to migrate between mobile and stationary devices in order to share functionalities and resources provided by the entire (mobile) environment. However, both the description and the execution of tasks which involve interactions of mobile users still require the executing device and its context to be known in advance in order to come up with a suitable user interface. Since this seems not appropriate for such decentralized and highly dynamic mobile processes, this work focuses on the integration of manual tasks on the respective ad-hoc creation of user interfaces at runtime. As an important prerequisite for that, this paper first presents an abstract and modality-independent interaction model to support the development and execution of user-centric mobile processes. Furthermore, the paper describes a prototype implementation for a corresponding system infrastructure component based on a service-oriented execution module, and, finally, shows its integration into the DEMAC (Distributed Environment for Mobility-Aware Computing) middleware.

    (Abstract only) We have innovatively designed and constructed three observatories each costing a few hundred USD for housing three small Schmidt-Cassegrain type telescopes namely, Celestron CGE925, Celestron CGE1400, Meade 12-inch LX200GPS. These observatories are completely different in design and are found to be perfectly usable for doing serious work on astronomical observation and measurements. The observatory with the Celestron CGE1400 telescope has been inducted, since January 2012, as one of the observatories of the international “Orion Project” headquartered at Phoenix, Arizona, which is dedicated for photometric and spectroscopic observations of five bright variable stars of the Orion constellation namely, Betelgeuse (alpha Ori), Rigel (beta Ori), Mintaka (delta Ori), Alnilam (epsilon Ori) and Alnitak (zeta Ori). Using this observatory, we have been producing BVRI photometric data for the five stars of the Orion project. The other observatory with the Meade 12-inch LX200GPS telescope is being inducted into service for CCD photometric study of SU UMa stars in connection with implementation of a project funded by Indian Space Research Organization (ISRO). In the present paper, we would like to describe our self-built observatories, our observational facilities, the BVRI photometric data that we acquired for the Orion project, and our future plan for observation of variable stars of interest.

  13. Plans should abstractly describe intended behavior

    Energy Technology Data Exchange (ETDEWEB)

    Planning is the process of formulating a potential course of action. How courses of action (plans) produced by a planning module are represented and how they are used by execution-oriented modules of a complex agent to influence or dictate behavior are critical architectural issues. In contrast to the traditional model of plans as executable programs that dictate precise behaviors, we claim that autonomous agents inhabiting dynamic, unpredictable environments can make better use of plans that only abstractly describe their intended behavior. Such plans only influence or constrain behavior, rather than dictating it. This idea has been discussed in a variety of contexts, but it is seldom incorporated into working complex agents. Experiments involving instantiations of our Adaptive Intelligent Systems architecture in a variety of domains have demonstrated the generality and usefulness of the approach, even with our currently simple plan representation and mechanisms for plan following. The behavioral benefits include (1) robust improvisation of goal-directed behavior in response to dynamic situations, (2) ready exploitation of dynamically acquired knowledge or behavioral capabilities, and (3) adaptation based on dynamic aspects of coordinating diverse behaviors to achieve multiple goals. In addition to these run-time advantages, the approach has useful implications for the design and configuration of agents. Indeed, the core ideas of the approach are natural extensions of fundamental ideas in software engineering.

    The mission of the NABIR program is to provide the fundamental science that will serve as the basis for the development of cost-effective bioremediation and long-term stewardship of radionuclides and metals in the subsurface at DOE sites. The focus of the program is on strategies leading to long-term immobilization of contaminants in place to reduce the risk to humans and the environment. Contaminants of special interest are uranium, technetium, plutonium, chromium, and mercury. The focus of the NABIR program is on the bioremediation of these contaminants in the subsurface below the root zone, including both vadose and saturated zones. The program is implemented through four interrelated scientific research elements (Biogeochemistry, Biomolecular Science and Engineering, Biotransformation, and Community Dynamics/Microbial Ecology); and through an element called Bioremediation and its Societal Implications and Concerns (BASIC), which addresses societal issues and potential concerns of stakeholders. The material presented at this year's workshop focuses on approximately 60 research projects funded in FY 2000-2002 by DOE's Office of Biological and Environmental Research (BER). Abstracts of NABIR research projects are provided in this book.

  16. Waste management research abstracts no. 14

    International Nuclear Information System (INIS)

    1983-04-01

    The present 14th issue is the second of the new series of Waste Management Research Abstracts, which are reappearing after a three-year suspension. The new series appears in a substantially innovated form. Although the objective of the publication is the same as before, namely to collect and disseminate information on research in progress in the field of nuclear waste management, the format for presentation of the information is a new data sheet in a standardized form, access to which will be made possible by different indexes. The 408 research data sheets contained in this issue have been collected during recent months, ending 15 January 1983, and reflect research currently in progress. They were sent by the Governments of twenty-five Member States, by the International Atomic Energy Agency, and by the Commission of the European Communities. Though the information contained in this publication covers a wide range of subjects in various countries, the WMRA should not be interpreted as providing a complete survey of on-going research in IAEA Member States

  18. Metaphors are physical and abstract: ERPs to metaphorically modified nouns resemble ERPs to abstract language

    Full Text Available Metaphorical expressions very often involve words referring to physical entities and experiences. Yet, figures of speech such as metaphors are not intended to be understood literally, word-by-word. We used event-related brain potentials (ERPs to determine whether metaphorical expressions are processed more like physical or more like abstract expressions. To this end, novel adjective-noun word pairs were presented visually in three conditions: (1 Physical, easy to experience with the senses (e.g., printed schedule; (2 Abstract, difficult to experience with the senses (e.g., conditional schedule; and (3 novel Metaphorical, expressions with a physical adjective, but a figurative meaning (e.g., thin schedule. We replicated the N400 lexical concreteness effect for concrete versus abstract adjectives. In order to increase the sensitivity of the concreteness manipulation on the expressions, we divided each condition into high and low groups according to rated concreteness. Mirroring the adjective result, we observed a N400 concreteness effect at the noun for physical expressions with high concreteness ratings versus abstract expressions with low concreteness ratings, even though the nouns per se did not differ in lexical concreteness. Paradoxically, the N400 to nouns in the metaphorical expressions was indistinguishable from that to nouns in the literal abstract expressions, but only for the more concrete subgroup of metaphors; the N400 to the less concrete subgroup of metaphors patterned with that to nouns in the literal concrete expressions. In sum, we not only find evidence for conceptual concreteness separable from lexical concreteness but also that the processing of metaphorical expressions is not driven strictly by either lexical or conceptual concreteness.

    Two design variants have been developed. A wire mesh sensor has two planes consisting of 16 wires each, with a diameter of 0.12 mm. The wires are symmetrically distributed across the diameter. Distance between the two planes is 1.5 mm. Some measuring points are covered in the corners of pipework. Particularly for the pressure surge experiments, a secon design was developed: the ``heavy`` mesh sensor consisting of thin rod-type electrodes made of stainless steel. The rods are lentiform in cross section in order to minimize the hydraulic resistance and the effects on flow processes. Sensors with 8 x 8 measuring points have been made for NW50 as well as sensors with 16 x 16 measuring points for NW100. They are designed for 7 MPa and a maximum of 150 C. They were used to visualize cavitation downstream of a quick stop valve located at the front end of a pipe about 200 m long. [Deutsch] Es wurden zwei Varianten entwickelt. Ein Drahtgittersensor verfuegt ueber zwei Ebenen zu je 16 Draehten mit einem Durchmesser von 0,12 mm. Die Draehte sind gleichmaessig ueber den Durchmesser angeordnet. Der Abstand zwischen den beiden Ebenen betraegt 1,5 mm. In Rohrleitungen werden in den Eckbereichen einige Messpunkte verdeckt. Speziell fuer die in der Arbeit beschriebenen Druckstossexperimente wurde ein zweiter Typ entwickelt: Der `schwere` Gittersensor mit staebchenfoermigen Elektroden aus nichtrostendem Stahl. Die Staebchen besitzen einen linsenfoermigen Querschnitt, um den hydraulischen Widerstand und die Stroemungsbeeinflussung klein zu halten. Es wurden sowohl Sensoren mit 8 x 8 Messpunkten fuer NW50 als auch ein Sensor mit 16 x 16 Messpunkten fuer NW100 hergestellt. Sie sind fuer 7 MPa und max. 150 C ausgelegt. Mit den Sensor wurde die Kavitation hinter einer Schnellschlussklappe visualisert, die sich am Anfang einer ca. 200 m langen Rohrleitung befindet. (orig.)
