    The installation of a radiology information system (RIS) connected to a hospital information system (HIS) and a picture archiving and communications system (PACS) seems mandatory for a nuclear medicine department in order to guarantee a high patient throughput. With these systems a fast transmission of reports, images to the in- and out-patients' wards and private practitioners is realized. Therefore, since April 2000, at the department of nuclear medicine of the university of Wuerzburg a completely DICOM based PACS has been implemented in addition to the RIS. With this system a DICOM based workflow is realized throughout the department of nuclear medicine for reporting and archiving. The PACS is connected to six gamma-cameras, a PET scanner, a bone densitometry system and an ultrasound device. The volume of image data archived per month is 4 GByte. Patient demographics are provided to the modalities via DICOM-Worklist. With these PACS components a department specific archive purely based on DICOM can be realized. During the installation process problems occurred mainly because of the complex DICOM standard for nuclear medicine. Related to that is the problem that most of the software implementations still contain bugs or are not adapted to the needs of a nuclear medicine department (particularly for PET). A communication software for the distribution of nuclear medicine reports and images based on techniques used for the worldwide web is currently tested. (orig.) [German] Fuer eine nuklearmedizinische Klinik ist ein Klinikinformationssystem (KIS) gekoppelt mit einem Radiologieinformationssystem (RIS) sowie einem Bildarchivierungs- und Verteilungssystem (PACS) unabdingbar, um einen schnellen Patientendurchsatz sowie die zeitnahe Uebermittlung von Befunden inklusive nuklearmedizinischen Bildern an zuweisende Stationen, Ambulanzen und externe Zuweiser zu gewaehrleisten.

    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.

    Clinical nuclear medicine has severely changed due to the technical and pharmacological developments within the last 15 years. An evaluation of the importance of nuclear medicine for treatment planning purposes in radiation therapy revealed in 20.6% of the cases relevant new information due to the scans. That nevertheless the demand for nuclearmedical examinations is decreasing might be a result of an increasing alienation between nuclear medicine and referring physicians of other specialities. Therefore a reapproach of nuclear medicine with her main clinical partners is desireable which could be achieved e.g. by exchange of rotating house officers, participation in tumor conferences and consiliary statements to scan indications. (orig.) [Deutsch] Die klinische Nuklearmedizin hat sich durch die technischen und pharmakologischen Entwicklungen der letzten 15 Jahre erheblich veraendert. Eine Evaluation der Bedeutung nuklearmedizinischer Verfahren fuer die Bestrahlungsplanung in der Strahlentherapie hat in 20,6% der Faelle eine untersuchungsbedingte, planungsrelevante Information erbracht, auf die nicht verzichtet werden konnte. Dass die Nachfrage nach nuklearmedizinischen Untersuchungen in diesem Bereich trotzdem ruecklaeufig ist, duerfte Ergebnis einer zunehmenden Entfremdung der Zuweiser aus den verwandten Faechern von der Nuklearmedizin sein. Es ist deshalb eine Wiederannaeherung der Nuklearmedizin an ihre klinischen Hauptpartner wuenschenswert, die durch Austausch von Rotationsassistenten, die Beteiligung an Tumorkonferenzen und die konsiliarische Stellungnahme zu Untersuchungsindikationen erreicht werden koennte.

    Nuclear medicine offers a wide range of possibilities to investigate dementia. Various SPECT and PET tracers will be introduced in this article first. Different questions concerning evaluation of dementia are discussed taking Alzheimer's disease (AD) as an example. It is important to perform nuclear medicine investigations on high technical level, using standardized methods as statistical parametric mapping (SPM) for evaluation. If neuroprotective therapies are available, an early diagnosis, the determination of risk factors and longitudinal investigations will be the focus of interest and the main goal of nuclear medicine. Apart from measuring cerebral perfusion and glucose metabolism the development of new ligands, concerning the cholinergic system and the visualization of amyloid plaques, is of great importance. (orig.) [German] Nuklearmedizin bietet bei der Erfassung und Beurteilung eines dementiellen Prozesses eine Vielzahl von Untersuchungsmoeglichkeiten. Anhand des Morbus Alzheimer (DAT) werden in dem vorliegenden Artikel neben einer kurzen Schilderung der zur Verfuegung stehenden Methoden die verschiedenen nuklearmedizinisch relevante Fragestellungen angefuehrt, zu deren Beantwortung die funktionelle Bildgebung Informationen liefern kann. Durch den Einsatz bestimmter, standardisierter Auswerteverfahren wie statistical parametric mapping (SPM) ist es moeglich, entscheidende Hinweise zur Diagnose und Differenzialdiagnose der DAT zu erlangen. In Zukunft werden, insbesondere bei einer Verfuegbarkeit neuroprotektiver Therapien, eine moeglichst fruehe Diagnosestellung und die Erfassung von Risikofaktoren sowie die Moeglichkeit einer Verlaufsbeobachtung in den Mittelpunkt des Interesses und in das Zentrum nuklearmedizinischer Untersuchungen ruecken. Vor allem fuer diese Anforderungen ist neben der qualitaetsvollen Untersuchung von zerebraler Perfusion und Glukosestoffwechsel eine Weiterentwicklung spezieller Liganden v. a. das cholinerge System betreffend und

    Strategic Realism: An Option for China' s Grand Strategy Song Dexing (4) [ Abstract] As a non-Western emerging power, China should positively adapt its grand strategy to the strategic psychological traits in the 21st century, maintain a realist tone consistent with the national conditions of China, and avoid adventurist policies while awaring both strategic strength and weakness. In the 21st century, China' s grand strategy should be based on such core values as security, development, peace and justice, especially focusing on development in particular, which we named "strategic realism". Given the profound changes in China and the world, strategic realism encourages active foreign policy to safe- guard the long-term national interests of China. Following the self-help logic and the fun- damental values of security and prosperity, strategic realism concerns national interests as its top-priority. It advocates smart use of power, and aims to achieve its objectives by optimizing both domestic and international conditions. From the perspective of diplomatic phi- losophy, strategic realism is not a summarization of concrete policies but a description of China' s grand strategy orientations in the new century.

    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.

    The supplemental information refers to the biological radiation effects, oncogenic and mutagenic effects, the biological significance of long-lived radionuclides. The conclusions to be drawn are summarized in the slightly simplified statement that the total additional radiation exposure due to the Chernobyl fallout is lower than the average annual, natural radiation exposure, which however varies within West Germany by a factor 6. The additional risk incurred in West Germany by the fallout certainly is very low, compared to other anthropogenic risks. (orig./HSCH).

    After the new radiation protection ordinance has come into effect with July 20th, 2001 the approval process for application of radiation substances or ionizing radiation in medical research changed considerably with respect to the responsibility of the Federal Office for Radiation Protection as the approval authority, the participation of an approved ethic committee, the inclusion of an expert for medical physics for planning and execution of the study as well as stricter regulations for cover clause. On the contrary, existing regulations have been facilitated since the effective dose limit for volunteers has been increased from 10 to 20 mSv and a central procedure for approval of multicenter studies has been introduced. Moreover, the application of radioactive substances or ionizing radiation for research in people without or with restricted legal capacity is no more totally prohibited. At present, changes of the radiation protection ordinance and the atomic law cover clause ordinance with respect to medical research are in discussion. (orig.) [German] Nach In-Kraft-Treten der neuen Strahlenschutzverordnung vom 20.07.2001 ergeben sich wesentliche Aenderungen des Genehmigungsverfahrens fuer die Anwendung radioaktiver Stoffe oder ionisierender Strahlung in der medizinischen Forschung bezueglich der Zustaendligkeit des Bundesamts fuer Strahlenschutz als Genehmigungsbehoerde, der Einschaltung einer akkreditierten Ethikkommission, der Hinzuziehung eines Medizinphysik-Experten bei der Studien-Planung und -Anwendung sowie verschaerfter Regelungen zur Deckungsvorsorge.

    The purpose of the inventory abstraction as directed by the development plan (CRWMS M and O 1999b) is to: (1) Interpret the results of a series of relative dose calculations (CRWMS M and O 1999c, 1999d). (2) Recommend, including a basis thereof, a set of radionuclides that should be modeled in the Total System Performance Assessment in Support of the Site Recommendation (TSPA-SR) and the Total System Performance Assessment in Support of the Final Environmental Impact Statement (TSPA-FEIS). (3) Provide initial radionuclide inventories for the TSPA-SR and TSPA-FEIS models. (4) Answer the U.S. Nuclear Regulatory Commission (NRC)'s Issue Resolution Status Report ''Key Technical Issue: Container Life and Source Term'' (CLST IRSR) (NRC 1999) key technical issue (KTI): ''The rate at which radionuclides in SNF [Spent Nuclear Fuel] are released from the EBS [Engineered Barrier System] through the oxidation and dissolution of spent fuel'' (Subissue 3). The scope of the radionuclide screening analysis encompasses the period from 100 years to 10,000 years after the potential repository at Yucca Mountain is sealed for scenarios involving the breach of a waste package and subsequent degradation of the waste form as required for the TSPA-SR calculations. By extending the time period considered to one million years after repository closure, recommendations are made for the TSPA-FEIS. The waste forms included in the inventory abstraction are Commercial Spent Nuclear Fuel (CSNF), DOE Spent Nuclear Fuel (DSNF), High-Level Waste (HLW), naval Spent Nuclear Fuel (SNF), and U.S. Department of Energy (DOE) plutonium waste. The intended use of this analysis is in TSPA-SR and TSPA-FEIS. Based on the recommendations made here, models for release, transport, and possibly exposure will be developed for the isotopes that would be the highest contributors to the dose given a release to the accessible environment. The inventory abstraction is important in assessing system performance because

(4) Answer the U.S. Nuclear Regulatory Commission (NRC)'s Issue Resolution Status Report ''Key Technical Issue: Container Life and Source Term'' (CLST IRSR) key technical issue (KTI): ''The rate at which radionuclides in SNF [spent nuclear fuel] are released from the EBS [engineered barrier system] through the oxidation and dissolution of spent fuel'' (NRC 1999, Subissue 3). The scope of the radionuclide screening analysis encompasses the period from 100 years to 10,000 years after the potential repository at Yucca Mountain is sealed for scenarios involving the breach of a waste package and subsequent degradation of the waste form as required for the TSPA-SR calculations. By extending the time period considered to one million years after repository closure, recommendations are made for the TSPA-FEIS. The waste forms included in the inventory abstraction are Commercial Spent Nuclear Fuel (CSNF), DOE Spent Nuclear Fuel (DSNF), High-Level Waste (HLW), naval Spent Nuclear Fuel (SNF), and U.S. Department of Energy (DOE) plutonium waste. The intended use of this analysis is in TSPA-SR and TSPA-FEIS. Based on the recommendations made here, models for release, transport, and possibly exposure will be developed for the isotopes that would be the highest contributors to the dose given a release

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 working group on information processing (IP) basics (in German: `IV-Grundlagen`) has prepared this contribution dealing with controlling applied to information processing. This new report, on the one hand, takes into consideration the role of the organizational IP unit as one offering its services to all sections of a company. On the other hand, information processing as an operational infrastructure influencing all business processes becomes increasingly important with respect to the competitiveness of the EVU. Therefore, quality management applied to IP projects and IP services must support this development.

  17. Completeness of Lyapunov Abstraction

    Directory of Open Access Journals (Sweden)

    Rafael Wisniewski

    2013-08-01

    Full Text Available In this work, we continue our study on discrete abstractions of dynamical systems. To this end, we use a family of partitioning functions to generate an abstraction. The intersection of sub-level sets of the partitioning functions defines cells, which are regarded as discrete objects. The union of cells makes up the state space of the dynamical systems. Our construction gives rise to a combinatorial object - a timed automaton. We examine sound and complete abstractions. An abstraction is said to be sound when the flow of the time automata covers the flow lines of the dynamical systems. If the dynamics of the dynamical system and the time automaton are equivalent, the abstraction is complete. The commonly accepted paradigm for partitioning functions is that they ought to be transversal to the studied vector field. We show that there is no complete partitioning with transversal functions, even for particular dynamical systems whose critical sets are isolated critical points. Therefore, we allow the directional derivative along the vector field to be non-positive in this work. This considerably complicates the abstraction technique. For understanding dynamical systems, it is vital to study stable and unstable manifolds and their intersections. These objects appear naturally in this work. Indeed, we show that for an abstraction to be complete, the set of critical points of an abstraction function shall contain either the stable or unstable manifold of the dynamical system.

    Owre, Sam; Shankar, Natarajan

    1997-01-01

    PVS (Prototype Verification System) is a general-purpose environment for developing specifications and proofs. This document deals primarily with the abstract datatype mechanism in PVS which generates theories containing axioms and definitions for a class of recursive datatypes. The concepts underlying the abstract datatype mechanism are illustrated using ordered binary trees as an example. Binary trees are described by a PVS abstract datatype that is parametric in its value type. The type of ordered binary trees is then presented as a subtype of binary trees where the ordering relation is also taken as a parameter. We define the operations of inserting an element into, and searching for an element in an ordered binary tree; the bulk of the report is devoted to PVS proofs of some useful properties of these operations. These proofs illustrate various approaches to proving properties of abstract datatype operations. They also describe the built-in capabilities of the PVS proof checker for simplifying abstract datatype expressions.

    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.

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.

    The calculation method of DIN V 18599 represents a very complex model for the estimation of the energy efficiency of buildings. The method is used for certificates too, thus, the number of users is quite high. This fact and the complexity of the method causes high demands on the related software products. Most of the end user software tools work with the calculation engine ibp18599kernel developed by Fraunhofer-Institut for Building Physics. There is a continuous quality control for both, the kernel and the user interfaces, i.e. the end user software. This paper gives an overview of the process of quality control as well as a documentation of a validation model used within this process, i.e. a complex administration building as a sample. (Abstract Copyright [2009], Wiley Periodicals, Inc.) [German] Mit dem Berechnungsverfahren der DIN V 18599 liegt ein umfassendes Berechnungsmodell fuer die energetische Bewertung von Gebaeuden vor.

Dieser ''Rechenmotor'' unterliegt einer steten Qualitaetskontrolle zur Sicherstellung der Berechnungsgenauigkeit. Der vorliegende Aufsatz stellt den Prozess der Qualitaetssicherung anhand eines neuen Validierungsbeispiels in Form eines komplexen Verwaltungsgebaeudes vor.

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.

  11. Abstract Objects of Verbs

    DEFF Research Database (Denmark)

    2014-01-01

    Verbs do often take arguments of quite different types. In an orthodox type-theoretic framework this results in an extreme polysemy of many verbs. In this article, it is shown that this unwanted consequence can be avoided when a theory of "abstract objects" is adopted according to which...... these objects represent non-objectual entities in contexts from which they are excluded by type restrictions. Thus these objects are "abstract'' in a functional rather than in an ontological sense: they function as representatives of other entities but they are otherwise quite normal objects. Three examples...

  13. Seismic Consequence Abstraction

    International Nuclear Information System (INIS)

    Gross, M.

    2004-01-01

    The primary purpose of this model report is to develop abstractions for the response of engineered barrier system (EBS) components to seismic hazards at a geologic repository at Yucca Mountain, Nevada, and to define the methodology for using these abstractions in a seismic scenario class for the Total System Performance Assessment - License Application (TSPA-LA). 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])

  18. Abstraction and art.

    Science.gov (United States)

    Gortais, Bernard

    2003-07-29

    In a given social context, artistic creation comprises a set of processes, which relate to the activity of the artist and the activity of the spectator. Through these processes we see and understand that the world is vaster than it is said to be. Artistic processes are mediated experiences that open up the world. A successful work of art expresses a reality beyond actual reality: it suggests an unknown world using the means and the signs of the known world. Artistic practices incorporate the means of creation developed by science and technology and change forms as they change. Artists and the public follow different processes of abstraction at different levels, in the definition of the means of creation, of representation and of perception of a work of art. This paper examines how the processes of abstraction are used within the framework of the visual arts and abstract painting, which appeared during a period of growing importance for the processes of abstraction in science and technology, at the beginning of the twentieth century. The development of digital platforms and new man-machine interfaces allow multimedia creations. This is performed under the constraint of phases of multidisciplinary conceptualization using generic representation languages, which tend to abolish traditional frontiers between the arts: visual arts, drama, dance and music.

  14. EBS Radionuclide Transport Abstraction

    International Nuclear Information System (INIS)

    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

    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.

  12. 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

    2005-08-25

    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 for the license application (TSPA-LA) 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-LA. 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.

    (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)

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.

    (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.

  11. Abstraction of Drift Seepage

    J.T. Birkholzer

    2004-01-01

    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 corrosion or radionuclide transport

    To the argument that the long half-life values of the most important products of fission represent an unacceptable burden for coming generations, the author retorts that this is an emotion-directed pseudo-argument. Anyone who ventures into deep geological strata, such as the final storage area Konrad, should also count in terms of geological periods. From this point of view, a million years - however difficult to imagine for the average human being - is not a very long time. Toxic chemical waste is accepted by society, even if the toxicity should remain for all time. The article is an extract from a lecture given by the author to the Franco-German Society for Science and Technology. (orig.) [German] Dem Argument, die langen Halbwertszeiten der wichtigsten Spaltprodukte beinhalte eine nicht zu verantwortende Belastung fuer die nachfolgenden Generationen, haelt Autor Tillessen entgegen, dass dies ein auf Emotionen abzielendes Scheinargument sei. Wer sich, wie zum Beispiel beim Endlager Konrad, in tiefe geologische Schichten begebe, duerfe auch in geologischen Zeitraeumen rechnen. Und da sei eine Million Jahre, so wenig vorstellbar das auch fuer den Durchschnitts-Menschen sei, eben keine allzulange Zeit. Chemische Giftabfaelle wuerden von der Gesellschaft akzeptiert, obwohl ihre Toxitaet ewig waehre. Der Beitrag des Autors ist ein Auszug aus einer Rede, die er vor der Deutsch-Franzoesischen Gesellschaft fuer Wissenschaft und Technik gehalten hat. Aus diesem Anlass hatte Tillessen vorgeschlagen, ein von einer Stiftung getragenes deutsch-franzoesisches Institut zu gruenden, dessen Aufgabe es sein soll, mit mehr Rationalitaet die von teutonischer Romantik dominierte Technikdiskussion zu versachlichen.

    The development of hydrology with its many practical applications in water management has led to a great demand for hydrometeorological data, variables derived from meteorological measurements, and models. The report shows the many fields in which meteorological data are required in hydrology and water management. Measuring networks and methods are described and critically assessed, including remote measurement by radar and satellite. For the hydrologist, the most important variables to be derived are the regional precipitation and evaporation, each with the error source and size. Other factors of interest are the snowbreak, the expected maximum precipitation (rain), the statistical derivation of strong rain, and regionalisation methods for all variables derived. These methods are presented. The possibilities of meteorology, especially (WMO) in the field of data transmission systems are assessed. (orig./KW) [Deutsch] Die Entwicklung der Hydrologie mit ihren zahlreichen wasserwirtschaftlichen Anwendungen hat zu einem grossen Bedarf an hydrometeorologischen Daten, aus meteorologischen Messungen abgeleiteten Groessen und auch an Modellen gefuehrt. Wo ueberall sich ein Bedarf an meteorologischen Daten in Hydrologie und Wasserwirtschaft eingestellt hat, ist in diesem Bericht zusammengefasst. Es werden die verschiedenen Messnetze und Messverfahren beschrieben und kritisch beurteilt, auch die Radar- und Satellitenfernerkundung gehoeren dazu. Fuer den Hydrologen zaehlt zu den wichtigsten abgeleiteten Groessen der Gebietsniederschlag und die Gebietsverdunstung, jeweils mit Angabe von Fehlerquelle und Fehlerschwankung. Von Interesse sind auch die Schneeschmelze, der vermutlich maximale Niederschlag (Regen), die statistische Ableitung von Starkregen und Regionalisierungsmethoden aller abgeleiteten Groessen.

    The presented case study by the Fraunhofer Institute ISE shows that the market for stationary electrochemical storage prices are currently too high for economical operation. In winter, a battery in Germany is not always fully loaded because of low sunlight. Therefore, the combination of a battery with a PV system at this time of year does not have enough full cycles to be economical. For more complete cycles of the year and consequently lower specific storage cost wind turbines or other power generators can be connected. Since - in contrast to lead acid batteries - there is no experience with long-term storage in lithium and redox flow batteries, this study is based on current forecasts. Compared to lithium-ion batteries, lead-acid and redox flow batteries have a lower efficiency, so that the investment costs of the battery must be lower because fewer savings can be achieved. Especially for short-term storage, the production costs must be reduced. The cost reduction potential of redox flow and lithium-ion batteries is due to the current technical state of development compared to lead acid batteries very high. This means that an economic operation in the future is possible with constant development of electricity and battery prices. [German] Die vorgestellte Fallstudie des Fraunhofer Instituts ISE zeigt, dass die Marktpreise fuer stationaere elektrochemische Speicher aktuell fuer einen wirtschaftlichen Betrieb zu hoch sind. Im Winter wird eine Batterie in Deutschland aufgrund der niedrigen Sonneneinstrahlung nicht immer komplett geladen.

    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. Die Solarisierung von Bebauungsplaenen beeinflusste Anordnung der Gebaeude hinsichtlich der Nutzung passivsolarer Gewinne sowie des Einsatzes von Systemen der aktiven Solarenergienutzung. Solarunterstuetzte Nahwaermenetze fuer Wohnsiedlungen werden ebenfalls beschrieben.

  3. Grounding abstractness: Abstract concepts and the activation of the mouth

    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.

    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.

    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. Comparison of means showed that among the study traits, the highest amount was obtained from complete irrigation, while irrigationat66 percenthad the least amount.

    Full Text Available The practice of teaching, in actuality, shows the necessity of teachers and students coming together to form a behavior that is different from the traditional model of teaching. The unity formed from various types of knowledge and the relation between theory and practice show themselves to be fundamental. Starting in 2002, and in search of this unity, a project that hoped to unify the disciplines taught in the second semester of the course in Administration was implemented. During the semester, a single work sought to relate the theories studied with the reality of an organization. Each professor evaluated the works from the point of view of his discipline, as well as the presentation, in general, of the group. It can be affirmed that seeking to bring together various types of knowledge necessarily passes to a rethinking of the postures of teachers and students.

Modal transition systems are recognized as valuable abstractions for model checking because they allow for the validation as well...... as refutation of safety and liveness properties. However, the algorithmic construction of finite abstractions from potentially infinite concurrent processes is a missing link that prevents their more widespread usage for model checking of concurrent systems. Our algorithm is a worklist algorithm using concepts...... from abstract interpretation and operating upon mappings from sets to intervals in order to express simultaneous over- and underapprox-imations of the multisets of process actions available in a particular state. We obtain a finite abstraction that is 3-valued in both states and transitions...

  3. Technical abstracts: Mechanical engineering, 1990

    1991-01-01

    This document is a compilation of the published, unclassified abstracts produced by mechanical engineers at Lawrence Livermore National Laboratory (LLNL) during the calendar year 1990. Many abstracts summarize work completed and published in report form. These are UCRL-JC series documents, which include the full text of articles to be published in journals and of papers to be presented at meetings, and UCID reports, which are informal documents. Not all UCIDs contain abstracts: short summaries were generated when abstracts were not included. Technical Abstracts also provides descriptions of those documents assigned to the UCRL-MI (miscellaneous) category. These are generally viewgraphs or photographs presented at meetings. An author index is provided at the back of this volume for cross referencing

  4. Metaphor: Bridging embodiment to abstraction.

    Science.gov (United States)

    Jamrozik, Anja; McQuire, Marguerite; Cardillo, Eileen R; Chatterjee, Anjan

    2016-08-01

    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.

    knowledge of which nanomaterials are used in which products. The SRU sees a need for greater transparency here to enable public authorities to react swiftly whenever evidence of health or environmental risks arises. Consumers should in principle enjoy freedom of choice. For this reason the SRU recommends creating a registry of nanoproducts and supplementation of existing labelling requirements. [German] In diesem Sondergutachten gibt der Sachverstaendigenrat fuer Umweltfragen (SRU) Empfehlungen fuer einen verantwortungsvollen, vorsorgeorientierten Umgang mit dieser Technologie. Ziel ist es, Innovationen zu ermoeglichen, aber auch Risiken fruehzeitig zu erkennen und zu mindern. Der SRU sieht dringenden Handlungsbedarf bei der Regulierung von Nanomaterialien und fordert mehr Transparenz bei Verbraucherprodukten ein. Sobald ein begruendeter Anlass zur Besorgnis besteht, muss nach dem Vorsorgeprinzip gehandelt und zwischen Risiken und Chancen abgewogen werden. Um dies zu ermoeglichen, sind zahlreiche rechtliche Aenderungen erforderlich. Nanomaterialien und Nano-Produkte unterliegen grundsaetzlich dem Stoff-, Produkt- und Umweltrecht. In der Praxis fuehren aber die Besonderheiten von Nanomaterialien dazu, dass nicht alle rechtlichen Instrumente greifen. So werden Nanomaterialien bei der Registrierung von Chemikalien und bei der Zulassung von Produkten nicht immer separat erfasst und damit bewertet. Der SRU empfiehlt, solche nanospezifischen Regelungsluecken schnell zu schliessen. Dazu ist es notwendig, Nanomaterialien verbindlich zu definieren, sie grundsaetzlich bei der Risikobewertung von Chemikalien wie eigenstaendige Stoffe zu behandeln und mit einem eigens auf sie zugeschnittenen Datensatz zu registrieren. Dabei duerfen die Risiken von Nanomaterialien nicht pauschal bewertet werden, weil manche Materialien nach heutigem Kenntnisstand unbedenklich sind, waehrend bei anderen ein Risikopotenzial besteht. Einen Anlass zur Besorgnis sieht der SRU vor allem bei der Verwendung von

    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. Nun kann dieser Beitrag zum Thema keine Einzelfallbetrachtung ersetzen bzw. abdecken. 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. Im Rahmen dieser Betrachtung koennen nur die Grundzuege einer derartigen Pruefung dargestellt werden. (orig.)

Die Vorgehensweise zur Absicherung der im Betrieb geforderten Qualitaet wird aufgezeigt und die dabei erforderlichen technischen und organisatorischen Massnahmen werden erlaeutert. (orig.)

  9. Knowledge acquisition for temporal abstraction.

    Science.gov (United States)

    Stein, A; Musen, M A; Shahar, Y

    1996-01-01

    Temporal abstraction is the task of detecting relevant patterns in data over time. The knowledge-based temporal-abstraction method uses knowledge about a clinical domain's contexts, external events, and parameters to create meaningful interval-based abstractions from raw time-stamped clinical data. In this paper, we describe the acquisition and maintenance of domain-specific temporal-abstraction knowledge. Using the PROTEGE-II framework, we have designed a graphical tool for acquiring temporal knowledge directly from expert physicians, maintaining the knowledge in a sharable form, and converting the knowledge into a suitable format for use by an appropriate problem-solving method. In initial tests, the tool offered significant gains in our ability to rapidly acquire temporal knowledge and to use that knowledge to perform automated temporal reasoning.

    2010-01-01

    The abstraction and over-approximation of protocols and web services by a set of Horn clauses is a very successful method in practice. It has however limitations for protocols and web services that are based on databases of keys, contracts, or even access rights, where revocation is possible, so...... that the set of true facts does not monotonically grow with the transitions. We extend the scope of these over-approximation methods by defining a new way of abstraction that can handle such databases, and we formally prove that the abstraction is sound. We realize a translator from a convenient specification...... language to standard Horn clauses and use the verifier ProVerif and the theorem prover SPASS to solve them. We show by a number of examples that this approach is practically feasible for wide variety of verification problems of security protocols and web services....

    Fibre-reinforced ceramics are extremely light, with a high fracture toughness, and have a high potential for applications in motor brakes. It is envisaged that they will last through the whole vehicle life. They can be used in passenger cars, industrial vehicles, high-speed trains, aircraft and in safety brakes in machines, plants and haulage systems. [German] Im Rahmen der Raumfahrt-Forschung wurde vom Deutschen Zentrum fuer Luft- und Raumfahrt (DLR) das Fluessigsilicier-Verfahren zur Herstellung von keramischen Verbundwerkstoffen entwickelt. Diese extrem leichten und bruchzaehen Faserkeramiken haben sich unter den besonderen Bedingungen des Weltraums beispielsweise fuer Hitzeschutzstrukturen von Raumfahrzeugen hervorragend bewaehrt. Darueber hinaus zeigten Untersuchungen ein hohes Anwendungspotenzial fuer neue Bremsen mit deutlich verbesserten Reibungs- und Verschleisseigenschaften. Weiterentwicklungen des keramischen Gefueges fuehrten zu innovativen Leichtbau- bzw. Hochleistungs-Bremsen auf der Basis dieser harten und hitzebestaendigen Verbundwerkstoffe. Bereits mit serienmaessigen Bremsbelaegen wurden die heute geltenden Verschleiss- und Reibwertanforderungen teilweise weit uebertroffen. Die Leistungsfaehigkeit heutiger Bremssysteme kann damit deutlich gesteigert und die ungefederte Masse des Fahrwerks drastisch reduziert werden. Mit der zielgerichteten Anpassung geeigneter Belaege auf die neuen Keramik-Bremsscheiben scheint erstmals ein Einsatz von Lebensdauerbremsen moeglich zu sein, deren geringe Verschleissraten einen Austausch der Bremsscheiben waehrend der Betriebszeit eines Fahrzeugs ueberfluessig machen. Neben der Verwendung dieser innovativen Leichtbaubremsen im PKW-Bereich wird zukuenftig deren Einsatz auch fuer Gefahrguttransporter, Hochgeschwindigkeitszuege, Flugzeuge und fuer Sicherheitsbremsen im Maschinen- und Anlagenbau sowie in der Foerdertechnik erwartet.

  3. The Complexity of Abstract Machines

    Directory of Open Access Journals (Sweden)

    Beniamino Accattoli

    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.

    In the context of their aerospace research activities, DLR (Deutsches Zentrum fuer Luft- und Raumfahrt) developed a new process for producing ceramic fibre composite materials that are extremely light and tough. Apart from their applications in aerospace engineering, they have great potential for motor brakes with improved friction and wear characteristics. Excellent results were achieved with the new materials even with conventional brake liners. With customised liners, brake life may be prolonged to match the car life. Further applications are expected in trucks for transport in hazardous materials, high-speed trains, aircraft, industrial machinery and plants, and conveyor systems.

    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

    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...

    2001-01-01

    Although the theory of well-posed Cauchy problems is reasonably understood, ill-posed problems-involved in a numerous mathematical models in physics, engineering, and finance- can be approached in a variety of ways. 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...

    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.

    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

    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).

    (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.

    Energy costs caused by heating, ventilation, air-conditioning and lighting systems, represent a significant portion of the total operating costs of a building. continuously rising prices of gas, oil and electricity increase the cost pressure on the building operators and users: energy efficiency is becoming a major factor for the competitiveness of a company. In the manufacturing sector, trade and hotel the energy costs have a direct impact on the company's margins. Thus, the willingness to invest in energy saving measures increased. [German] Energiekosten, verursacht durch Heizungs-, Lueftungs-, Klima- und Beleuchtungsanlagen, stellen einen signifikanten Anteil der Gesamtbetriebskosten eines Gebaeudes dar. Kontinuierlich steigende Preise fuer Gas, Oel und Elektrizitaet erhoehen den Kostendruck auf die Gebaeudebetreiber und -nutzer: Energieeffizienz wird zu einem bestimmenden Faktor fuer die Wettbewerbsfaehigkeit eines Unternehmens. Im produzierenden Gewerbe, im Handel und im Hotelgewerbe haben Energiekosten einen direkten Einfluss auf die Margen des Unternehmens. Dadurch erhoeht sich die Bereitschaft, in Energiesparmassnahmen zu investieren.

  5. 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

  6. An introduction to abstract algebra

    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 ...

    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.

    bzw. -kompensation werden zurzeit untersucht oder schon in der Klinik angewendet. Die Sonographie ist eine vielversprechende Option, die nun kurz vor der klinischen Implementierung steht. Hoher Weichteilkontrast, Echtzeitfaehigkeit, Verzicht auf ionisierende Strahlung sowie relativ geringe Anschaffungskosten zeichnen den Ultraschall besonders fuer diesen Zweck aus. Ultraschallbewegungstracking ist ein bildbasierter Ansatz, d. h. das Zielvolumen oder eine damit verbundene Struktur werden direkt beobachtet und deren Bewegung automatisch auf dem Ultraschallbild nachverfolgt. Diverse Algorithmen stehen derzeit zur Verfuegung, die sowohl aus 2-D- als auch 3-D-Bildern die aktuellen Koordinaten einer Zielstruktur liefern. Die Auswahl eines passenden Schallfensters ist jedoch nicht trivial, und ein Goldstandard fuer die Positionierung und Halterung des Schallkopfs wurde noch nicht erarbeitet. Ausserdem sind die Verarbeitung der Koordinateninformation an der Therapieeinheit sowie die dynamische Anpassung des Strahlfeldes grosse Herausforderungen. Es ist offen, ob sich Ultraschallbewegungstracking in der klinischen Routine etabliert, obwohl alle technischen Voraussetzungen als erfuellt angesehen werden koennen, sodass weiterhin spannende Entwicklungen in diesem Forschungsfeld zu erwarten sind.

  14. 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.

    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. Spectrophotometry of Symbiotic Stars (Abstract)

    Science.gov (United States)

    Boyd, D.

    2017-12-01

    (Abstract only) Symbiotic stars are fascinating objects - complex binary systems comprising a cool red giant star and a small hot object, often a white dwarf, both embedded in a nebula formed by a wind from the giant star. UV radiation from the hot star ionizes the nebula, producing a range of emission lines. These objects have composite spectra with contributions from both stars plus the nebula and these spectra can change on many timescales. Being moderately bright, they lend themselves well to amateur spectroscopy. This paper describes the symbiotic star phenomenon, shows how spectrophotometry can be used to extract astrophysically useful information about the nature of these systems, and gives results for three symbiotic stars based on the author's observations.

    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.)

    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.)

  10. An abstract approach to music.

    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.

  12. Handedness shapes children's abstract concepts.

    Can children's handedness influence how they represent abstract concepts like kindness and intelligence? Here we show that from an early age, right-handers associate rightward space more strongly with positive ideas and leftward space with negative ideas, but the opposite is true for left-handers. In one experiment, children indicated where on a diagram a preferred toy and a dispreferred toy should go. Right-handers tended to assign the preferred toy to a box on the right and the dispreferred toy to a box on the left. Left-handers showed the opposite pattern. In a second experiment, children judged which of two cartoon animals looked smarter (or dumber) or nicer (or meaner). Right-handers attributed more positive qualities to animals on the right, but left-handers to animals on the left. These contrasting associations between space and valence cannot be explained by exposure to language or cultural conventions, which consistently link right with good. Rather, right- and left-handers implicitly associated positive valence more strongly with the side of space on which they can act more fluently with their dominant hands. Results support the body-specificity hypothesis (Casasanto, 2009), showing that children with different kinds of bodies think differently in corresponding ways.

    (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.

    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. The main topics to be discussed at the conference are: 1) At and beyond the drip line, 2) Shell structure far from stability, 3) Fusion reactions and synthesis of heavy and superheavy nuclei, 4) Dynamics and thermodynamics of exotic nuclear systems, 5) Radioactive ion beams in nuclear astrophysics, 6) New modes of radioactivity, 7) Fundamental interactions, 8) Applications in other fields, 9) Future RIB facilities, 10) Production and manipulation of RIB, and 11) Working group meetings on synergy in instrumentation and data acquisition. This document gathers only the abstracts of the papers. (authors)

  15. Attracting Girls into Physics (abstract)

    2009-04-01

    A recent international study of women in physics showed that enrollment in physics and science is declining for both males and females and that women are severely underrepresented in careers requiring a strong physics background. The gender gap begins early in the pipeline, from the first grade. Girls are treated differently than boys at home and in society in ways that often hinder their chances for success. They have fewer freedoms, are discouraged from accessing resources or being adventurous, have far less exposure to problem solving, and are not encouraged to choose their lives. In order to motivate more girl students to study physics in the Assiut governorate of Egypt, the Assiut Alliance for the Women and Assiut Education District collaborated in renovating the education of physics in middle and secondary school classrooms. A program that helps in increasing the number of girls in science and physics has been designed in which informal groupings are organized at middle and secondary schools to involve girls in the training and experiences needed to attract and encourage girls to learn physics. During implementation of the program at some schools, girls, because they had not been trained in problem-solving as boys, appeared not to be as facile in abstracting the ideas of physics, and that was the primary reason for girls dropping out of science and physics. This could be overcome by holding a topical physics and technology summer school under the supervision of the Assiut Alliance for the Women.

    This paper offers a brief overview of the historical and technical aspects of aquifer thermal energy storage and its use potential in commercial buildings in Canada. Aquifer thermal energy storage systems are now attractive both for new commercial buildings in Canada and for some already existing ones. This holds true especially of the Atlantic region, where fuel costs are rising and electric power rates vary according to the time of day. The simple pay-back period for ATES systems is between zero and five years. The economic aspects of the use of ATES systems in buildings are pointed out. (orig./BWI) [Deutsch] Dieser Beitrag gibt eine kurze Uebersicht der historischen und technischen Aspekte der Waermespeicherung in Aquiferen und deren Verwendungspotential in kommerziellen Gebaeuden in Kanada. Aquiferwaermespeicherungssysteme sind nunmehr attraktiv sowohl fuer neue als auch fuer manche bereits bestehenden kommerziellen Gebaeude in Kanada. Dies gilt insbesondere fuer die atlantische Region wegen der dort steigenden Kosten fuer Brennstoffe und tageszeitabhaengigen fuer elektrischen Strom. Die einfache Amortisationszeit fuer ATES-Systeme liegt zwischen null und fuenf Jahren. Die wirtschaftlichen Gesichtspunkte des Einsatzes von ATES-Systemen in kommerziellen Gebaeuden werden angefuehrt. (orig./BWI)

    Nuclear medicine operates with open radioactive substances in diagnostics and therapeutics. Diagnostic methods (as scintiscanning, SPECT, PET/CT) use so called radioactive tracer isotopes, their chemical exchange with stable isotopes is bound to metabolic processes. Beta or alpha emitting substances are used for therapeutic purposes. The 3D activity distribution is calculated using libraries and weighting factors recommended by ICRP based on phantom measurements. The contribution summarizes possible exposures of the medical personnel and radiation hygienic measures for personnel and patients' relatives. Further issues are the recommended threshold value measurements and the radioactive waste disposal.

    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.)

    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.

    Oil-free compressors are lubricated with special materials in dry operation. The technology was developed 35 years ago by the Swiss company, Fritz Haug AG. Originally developed for 10 - 40 bar, oil-free compressors are now available for both the low-pressure and high-pressure range. [German] Unter dem Begriff ''oellose Kompressoren'' versteht man Verdichter, die in der ganzen Anlage keinen Tropfen Oel verwenden, weder im Fuehrungs- und Verdichtungstell noch im Triebwerk. Die Schmierung erfolgt mit speziellen Materiallen im Trockenlauf. Die Technik der oellosen und trockenlaufenden Kolbenkompressoren wurde bereits vor rund 35 Jahren von der schweizer Firma Fritz Haug AG entwickelt. Anfaenglich war die Anwendung der Verdichtung von Luft auf 10 bis 40 bar vorbehalten. Durch Weiterentwicklungen in neue Materiallen und in der Konstruktion besteht heute auch ein umfangreiches Sortiment an Kompressoren fuer die oellose und trockene Verdichtung von Gasen fuer den Nieder- und Hochdruckbereich.

    In some of the federal states of Germany the licensing of new or the laying or existing high-voltage overhead lines requires an environmental impact assessment. For many utility companies, however, environmental impact assessments for high-voltage lines are virgin territory. Experience shows that preparing the documentation is not a major problem. Questions usually arise over details such as the calculation of possible incidents or the comparison of different layouts. The authors describes general approaches and strategies and looks at specific problems. (orig.)

Fuer viele Energieversorgungsunternehmen ist die Erarbeitung von Umweltvertraeglichkeitsstudien fuer Hochspannungsleitungen aber noch Neuland. Praxiserfahrungen zeigen, dass die Erarbeitung der erforderlichen Unterlagen ohne groessere Schwierigkeiten moeglich ist. Fragen ergeben sich dabei aber bei speziellen Details, z.B. bei der Betrachtung von moeglichen Stoerfaellen oder beim Vergleich von Trassenvarianten. Der Verfasser skizziert das allgemeine Vorgehen und erlaeutert ausfuehrlich die Detailprobleme. (orig.)

    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

    With their high efficiency and modular structure, fuel cells are an attractive option for decentral power supply. An important component of decentral power supply systems is the power-electronic control element for supply of electric power from the fuel cell to the three-phase electricity grid. Control elements can be constructed of a unidirectional DC/DC converter with a current inverter connnected in series. The investigation focused on the development of the DC/DC converter with minimum constructional and control requirements and optimum adaption of the DC/DC converter to the characteristics of the fuel cell. (orig.) [German] Die Brennstoffzelle stellt mit ihrem hohen Wirkungsgrad und ihrem modularen Aufbau eine attraktive Option fuer die Verwendung in einem dezentralen Energieversorgungssystem dar. Eine wichtige Komponente des dezentralen Energieversorgungssystems sind die leistungselektronischen Stellglieder fuer die Einspeisung der elektrischen Energie aus der Brennstoffzelle in das dreiphasige Netz. Die leistungselektronischen Stellglieder koennen aus einem undirektionalen DC/DC-Wandler und einem nachgeschalteten Wechselrichter realisiert werden. Die Entwicklung des DC/DC-Wandlers mit einem moeglichst geringeren Bauelemente- und Steuerungsaufwand fuer diese leistungselektronischen Stellglieder und die Anpassung des DC/DC-Wandlers an die Eigenschaften der Brennstoffzelle war das Ziel dieser Arbeit.

    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 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...... are allowed. Our approach uses counterexample-guided abstraction refinement: whenever the current abstraction is too coarse and induces nondeterministic behavior, the abstraction is refined automatically. Using Tomte, a prototype tool implementing our algorithm, we have succeeded to learn – fully......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...

    2009-01-01

    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...... and implementing abstractions will improve the applicability of model checking in practice....

  3. Minimalism in architecture: Abstract conceptualization of architecture

    Directory of Open Access Journals (Sweden)

    Vasilski Dragana

    2015-01-01

    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.

  4. Analysis of complex networks using aggressive abstraction.

    Energy Technology Data Exchange (ETDEWEB)

    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.

  19. Hydrogen abstraction reactions by amide electron adducts

    International Nuclear Information System (INIS)

    Sevilla, M.D.; Sevilla, C.L.; Swarts, S.

    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)

  5. Abstract Spatial Reasoning as an Autistic Strength

    Stevenson, Jennifer L.; Gernsbacher, Morton Ann

    2013-01-01

    Autistic individuals typically excel on spatial tests that measure abstract reasoning, such as the Block Design subtest on intelligence test batteries and the Raven’s Progressive Matrices nonverbal test of intelligence. Such well-replicated findings suggest that abstract spatial processing is a relative and perhaps absolute strength of autistic individuals. However, previous studies have not systematically varied reasoning level – concrete vs. abstract – and test domain – spatial vs. numerical vs. verbal, which the current study did. Autistic participants (N = 72) and non-autistic participants (N = 72) completed a battery of 12 tests that varied by reasoning level (concrete vs. abstract) and domain (spatial vs. numerical vs. verbal). Autistic participants outperformed non-autistic participants on abstract spatial tests. Non-autistic participants did not outperform autistic participants on any of the three domains (spatial, numerical, and verbal) or at either of the two reasoning levels (concrete and abstract), suggesting similarity in abilities between autistic and non-autistic individuals, with abstract spatial reasoning as an autistic strength.

    Full Text Available The paper examines the abstract genre from the perspectives of English for Specific Purposes (ESP practitioners and information professionals. It aims to determine specific interdisciplinary interests in the abstract, and to explore areas of collaboration in terms of research and pedagogical practices. A focus group (FG comprising information professionals from the Division of Information Studies, Nanyang Technological University, Singapore, convened for a discussion on the subject of abstracts and abstracting. Two major issues that have significant implications for ESP practices emerged during the discussion. While differences in terms of approach to and objectives of the abstract genre are apparent between information professionals and language professionals, the demands for specific cognitive processes involved in abstracting proved to be similar. This area of similarity provides grounds for awareness raising and collaboration between the two disciplines. While ESP practitioners need to consider adding the dimension of information science to the rhetorical and linguistic scaffolding that they have been providing to novice-writers, information professionals can contribute useful insights about the qualities of abstracts that have the greatest impact in meeting the end-users' needs in information search.

    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.)

    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.

As with denotational semantics we may also view abstract interpretations as programs and examine the implementation. The main focus...... in this paper is to show that results from higher-order strictness analysis may be used more generally as fixpoint operators for higher-order functions over lattices and thus provide a technique for immediate implementation of a large class of abstract interpretations. Furthermore, it may be seen...

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...

  16. Multi-Chip-Modul-Entwicklung fuer den ATLAS-Pixeldetektor

    CERN Document Server

    Stockmanns, Tobias

    2004-01-01

    Abstract: The innermost layer of the ATLAS tracking system is a silicon pixel detector. The use of radiation tolerant components is mandatory due to the harsh radiation environment. The smallest independent component of the pixel detector is a hybride pixel module consisting of a large oxygen enriched silicon sensor and 16 specifically developed ASICs. To achieve the necessary radiation tolerance the ASICs are produced in a 0.25 µm technology in combination with special design techniques. The measurements of the readout electronics during all stages of production of a full module are presented and the performance of the modules is compared with the strict requirements of the ATLAS pixel detector. Furthermore a new powering scheme for pixel detectors is presented, aiming at reducing the total power consumption, the material for the electrical services and the amount of power cables. The advantages and disadvantages of this concept are discussed on the example of the ATLAS pixel detector with pixel modules mo...

    High alloyed superaustenitic steels and NiCrMo alloys are recommended in consequence of the results of extensive laboratory corrosion experiments under the strong corrosive conditions with up to 360 g chloride content at temperatures up to 85 C. Because results of laboratory corrosion tests are only of limited relevance to the behaviour in practice, field tests were carried out with immersion of welded materials and of heat exchanger tubes under operating conditions of an evaporation plant for waste water from flue gas desulphurization of a coal-fired power plant. Different kinds of high alloy superaustenitic steels and NiCrMo alloys were studied as TIG-welded specimens in immersion tests. (orig.) [German] Hochlegierte Sonderedelstaehle und NiCrMo-Legierungen empfehlen sich aufgrund der Ergebnisse umfassender Laboruntersuchungen unter den stark korrosiven Bedingungen fuer Eindampfanlagen fuer Abwasser aus der Nassreinigung von Rauchgasen von Grossfeuerungsanlagen mit bis zu 360 g/l Chloridgehalt und Temperaturen bis zu 85 C. Weil aber Ergebnisse von Laborpruefungen nur begrenzte Aussagefaehigkeit fuer das Verhalten unter Praxisbedingungen haben, wurden Feldversuche mit der Auslagerung geschweisster Werkstoffe und von Waermetauscherrohren unter Betriebsbedingungen einer Eindampfanlage fuer Abwasser aus der Rauchgasentschwefelung eines kohlebefeuerten Kraftwerks durchgefuehrt.

  1. Photochemical hydrogen abstractions as radiationless transitions

    International Nuclear Information System (INIS)

    Burrows, H.D.; Formosinho, S.J.

    1977-01-01

    The tunnel-effect theory of radiationless transitions is applied to the quenching of the uranyl ion excited state by aliphatic compounds. The most important mechanism kinetically is suggested to involve chemical quenching via hydrogen abstraction, and rates for these reactions are analysed theoretically. Good agreement between theory and experiment is observed for a number of alcohols and ethers, and the reactions are suggested to possess considerable charge-transfer character. With t-butanol it is suggested that abstraction occurs preferentially from the hydroxylic hydrogen. Theoretical analysis of the rates of hydrogen abstraction from carboxylic acids suggests that the reaction geometry in this case may be different from the reaction with alcohols or ethers. The possibility that excited uranyl ion can abstract a hydrogen atom from water is examined, and theoretical evidence is presented to suggest that this is the main route for deactivation of uranyl ion lowest excited state in water at room temperature.

    2017-09-01

    Mathematical abstraction is an important process in teaching and learning mathematics so pre-service mathematics teachers need to understand and experience this process. One of the theoretical-methodological frameworks for studying this process is Abstraction in Context (AiC). Based on this framework, abstraction process comprises of observable epistemic actions, Recognition, Building-With, Construction, and Consolidation called as RBC + C model. This study investigates and analyzes how pre-service mathematics teachers constructed and consolidated concept of Parallel Coordinates in a group discussion. It uses AiC framework for analyzing mathematical abstraction of a group of pre-service teachers consisted of four students in learning Parallel Coordinates concepts. The data were collected through video recording, students’ worksheet, test, and field notes. The result shows that the students’ prior knowledge related to concept of the Cartesian coordinate has significant role in the process of constructing Parallel Coordinates concept as a new knowledge. The consolidation process is influenced by the social interaction between group members. The abstraction process taken place in this group were dominated by empirical abstraction that emphasizes on the aspect of identifying characteristic of manipulated or imagined object during the process of recognizing and building-with.

  12. 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.

    A comparison of the measured and simulated values of three collector types shows that evacuated tube collectors are superior to transparent-insulation flat collectors in the case of high-temperature uses. At temperatures of 150 C and above good results were obtained using evacuated tube collectors with compound parabolic concentrators manufactured by Microtherm. CORTEC collectors are suited for temperatures in the range of 100 C to 150 C provided that the surface ratio is irrelevant. Costs play a decisive role when selecting systems. The results obtained show that improved transparent-insulation flat collectors can compete with evacuated tube collectors in the 100 C to 150 C temperature range. (orig.) [Deutsch] Ein Vergleich der gemessenen und simulierten Werte der drei Kollektoren zeigt, dass die Vakuumroehrenkollektoren fuer den Einsatz in Hochtemperaturanwendungen dem mit transparenter Waermedaemmung isolierten Flachkollektor ueberlegen sind. Der Vakuumroehrenkollektor mit CPC von Microtherm erzielt gute Resultate ab 150 C und mehr. Wogegen der CORTEC-Kollektor fuer den Einsatz im Temperaturbereich zwischen 100 C und 150 C geeignet ist, solange das Flaechenverhaeltnis keine Rolle spielt. Wie fuer die meisten Anwendungen spielen die Kosten eine entscheidende Rolle fuer die Wahl des eingesetzten Systems. Die Resultate zeigen, dass ein verbesserter mit TWD ausgeruesteter Flachkollektor im Temperaturbereich von 100 C bis 150 C konkurrenzfaehig zu Vakuumroehrenkollektoren sein kann. (orig.)

    Doubtless assistance systems should contribute to the safety of car driving. They support simultaneously a comfortable use of the car. Especially the operation comfort is characterised by clarity, self explaining, robustness against errors, and so on. Operation comfort doesn't give an inessential contribution to a reliable and appropriate interaction between driver and vehicle that means also a contribution to a reliable function of the total system and thereby to safety. Therefore the subjective experience of assistance systems is of excellent importance with view on the subjective and public confidence in new assistance systems. Are they seen rather as a gain of comfort, as it is preferred by the producer by reasons of production related liability, or as an easing of the driver's behaviour providing safety? Consists in the last called tendency a new kind of danger? In this connection juristic problems may not be unmentioned. The driver may not or not completely be called to account for procedures on which he has no influence or thinks to have no influence. In this case the account for the not compensated damage is contributed to the producer of the system. Therefore, by considering human characteristics and abilities of the driver during the development of assistance systems unwanted juristic consequences should be prevented. (orig.) [German] Assitenzsysteme sollen zweifellos einen Beitrag fuer die Sicherheit des Autofahrers liefern. Zugleich dienen sie aber auch fuer eine komfortable Nutzung des Fahrzeugs.

    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.

    2000-07-01

    Modern recording systems form the basis for competitive services. They are, however, only successful when integrated precisely into a lean running organization. By means of practical examples the necessity to place great emphasis on the costs of a system besides the investment costs when deciding about a recording system, will be examined. The significant changes on the energy market and the increasing demand of the housing economy for a comprehensive offer of services from the supply industry are main initiators for a whole new line of businesses on the supply economy sector. The great challenge for the supply industry lies in the task to install lean and effective system which are on one hand reliable and easy to handle for the whole duration of the contract and on the other hand are so cost efficient, that an adequate profitability can be ensured (see also: 'The secret winners', Zfk October 1999). A decisive factor for this reason is the metering technology, which has to ensure for the whole duration of the contract that correct consumption values are registered, on the basis of which as fast and punctual as possible a legally safe invoicing can be prepared. (orig.) [German] Moderne Erfassungssysteme bilden die Grundlage fuer wettbewerbsfaehige Dienstleistungen, die jedoch erst bei sauberer Einbindung in eine schlanke Ablauforganisation erfolgreich sind. Anhand von Praxisbeispielen wird die Notwendigkeit betrachtet, bei der Entscheidung fuer ein Erfassungssystem neben den Investitionskosten den Systemkosten entscheidendes Gewicht zu verleihen.

    The Institut fuer Nukleare Entsorgungstechnik performs research and development work on the treatment, solidification and final storage of radioactive wastes. The main target of the work is to develop processes and concepts for a safe disposal of radioactive wastes from nuclear plants. The work on waste treatment is carried out within the framework of the reprocessing and waste treatment project. It comprises of the development and characterization of ultimate storable waste products as well as the development of processes for the treatment and solidification of radioactive wastes mainly from reprocessing irradiated nuclear fuels. The studies on the ultimate storage are carried out together with the 'Gesellschaft fuer Strahlen- und Umweltforschung'. Their main concern is the analysis of processes in the neighbourhood of ultimate storage (waste product, packing, filling and immediate surrounding storage medium) for normal and accident conditions and their safety technical optimization. The report is supplemented by a list of publications and lectures of the institute coworkers in 1980. (orig./RB) [de

    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)

    Tools and wear parts for compacting tools are subjected to high abrasive wear and mechanical loading at elevated temperatures. MMC's based in iron- or nickel with hard particles are developed and investigated. The materials were manufactured from powders by hot isostatic pressing (HIP) and subsequently heat treated. Diffusion between hard phases and metal matrix brings about certain micro structures which were tested with respect to the resistance against sliding abrasion at room and elevated temperatures. Three-point bending tests and thermal cycling of the material was utilized to characterise the mechanical behaviour. Based on this results a toolkit for a roller press for briquetting was produced and brought into application. (orig.) [German] Werkzeuge und Verschleissteile fuer die Verarbeitung von mineralischen Guetern bei erhoehter Temperatur unterliegen sowohl hohem abrasivem Verschleiss als auch hohen mechanischen Lasten. Es werden hartphasenhaltige Verbundwerkstoffe auf Eisen- und Nickelbasis entwickelt und untersucht. Die Fertigung dieser MMC's erfolgt durch heiss isostatisches Pressen (HIP) und anschliessende Waermebehandlung.

    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.

    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.

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

    Energy Technology Data Exchange (ETDEWEB)

    Pust, M. [TECSOL GmbH, Friedeburg (Germany)

    2014-07-01

    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. Es reicht fuer die Akzeptanz des Vorhabens haeufig nicht mehr aus, dass ein Vorhabentraeger den rechtlich vorgegebenen Weg des Genehmigungsprozesses beschreitet und die betroffenen Buerger erst

  14. Abstract Interpretation as a Programming Language

    Directory of Open Access Journals (Sweden)

    Mads Rosendahl

    2013-09-01

    Full Text Available In David Schmidt's PhD work he explored the use of denotational semantics as a programming language. It was part of an effort to not only treat formal semantics as specifications but also as interpreters and input to compiler generators. The semantics itself can be seen as a program and one may examine different programming styles and ways to represent states. Abstract interpretation is primarily a technique for derivation and specification of program analysis. As with denotational semantics we may also view abstract interpretations as programs and examine the implementation. The main focus in this paper is to show that results from higher-order strictness analysis may be used more generally as fixpoint operators for higher-order functions over lattices and thus provide a technique for immediate implementation of a large class of abstract interpretations. Furthermore, it may be seen as a programming paradigm and be used to write programs in a circular style.

The language allows immediate object construction, and it is possible to use the constructed objects for concrete problem solving tasks. Classes...... restrictive. As a central mechanism, weakly classified objects are allowed to borrow methods from each other. ASL2 supports class generalization, as a counterpart to class specialization and inheritance in mainstream object-oriented programming languages.

    This volume collects together a number of important papers concerning both the method of abstraction generally and the use of particular abstraction principles to reconstruct central areas of mathematics along logicist lines. Gottlob Frege's original logicist project was, in effect, refuted by Russell's paradox. Crispin Wright has recently revived Frege's enterprise, however, providing a philosophical and technical framework within which a reconstruction of arithmetic is possible. While the Neo-Fregean project has recieved extensive attention and discussion, the present volume is unique in pre

    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...

  3. Embodied cognition, abstract concepts, and body manipulation

    Directory of Open Access Journals (Sweden)

    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.

  11. Content Abstract Classification Using Naive Bayes

    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.

  14. Abstraction of man-made shapes

    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.

    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. [German] Die Energiewende im Waermesektor ist kein Selbstlaeufer und kommt zu langsam voran. Das ist alarmierend, da der Waerme-/Kaeltesektor fuer ueber die Haelfte des Endenergiebedarfs verantwortlich ist. 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''. Die Beitraege dieses Tagungsbandes praesentieren aktuelle Forschungsergebnisse und zeigen Wege auf, um die Waermewende technisch, wirtschaftlich und politisch

    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. Deutschland leistete in den letzten Jahren wichtige Beitraege zu dieser Entwicklung, sowohl beim Aufbau neuer Fertigungskapazitaeten fuer Solarzellen, als auch bei der Entwicklung neuer Photovoltaik-Materialien bzw. -Materialkombinationen und auf den Gebieten der Technologie und des Anlagenbaus. Der Anteil Thueringens und Sachsens an dieser positiven Entwicklung ist groesser als generell vermutet. In Thueringen entstanden zwei Unternehmen fuer die Solarzellenproduktion, der saechsische Vakuumbeschichtungs-Anlagenbau war am Aufbau fast aller neuen deutschen Fertigungsstaetten beteiligt.

  20. Abstraction of Drift-Scale Coupled Processes

    International Nuclear Information System (INIS)

    Francis, N.D.; Sassani, D.

    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

  4. Old Romanian pluralized mass and abstract nouns

    Directory of Open Access Journals (Sweden)

    Gabriela Pană Dindelegan

    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.

  5. 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.

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.

  18. The abstract representations in speech processing.

    Science.gov (United States)

    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.

  19. SATURATED ZONE FLOW AND TRANSPORT MODEL ABSTRACTION

    International Nuclear Information System (INIS)

    B.W. ARNOLD

    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

  20. Ad Oculos. Images, Imagination and Abstract Thinking

    Directory of Open Access Journals (Sweden)

    Alessandra Cirafici

    2018-03-01

    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.

    Energy supply companies (resellers) and electric utilities as traders in the liberalized markets increasingly focus their activities on their core businesses and offer their capabilites also in other branches of industry, thus achieving synergistic effects. The evolution of e-commerce in the energy supply sector in Germany is described in this article, and recommendations are given to companies as to suitable change management strategies for successful marketing and procurement via the world wide web, using IP technologies as a basis for transactions. (CB) [German] Energieversorgungsunternehmen (EVU) besinnen sich auf ihre Kernkompetenzen, bieten diese auch in anderen Branchen an und erzielen damit Synergieeffekte. Ein weiterer Aspekt ist die zunehmende Vernetzung der europaeischen Stromnetze. Die Konvergenz der Maerkte wird ferner durch den Einsatz von IP(Internet-Protokoll)-Technologien vorangetrieben, da das Internet eine Informations- und Transaktionsplattform fuer saemtliche Marktteilnehmer schafft. Welche diesbezueglichen Transformationsstrategien von den EVU bereits heute zu ergreifen sind, wird anschaulich aus einem hierzu entwickelten Modell abgeleitet. (orig./CB)

    Within a joint project supported by the Free State Saxony a novel bearing and transport system was developed. The prototype is based on the combination of the magnetic bearing technique using high temperature-superconductors with a non-contacting linear drive. This non-contracting 'lift' is free from friction and contaminations due to wear and therefore predestinated for applications in clean rooms, e.g. in the microelectronic technology. (orig.) [German] Im Rahmen eines Verbundprojektes, gefoerdert vom Freistaat Sachsen, wurde ein neuartiges Lager- und Transportsystem in Form einer Kombination der supraleitenden Magnetlagertechnik mit Hochtemperatursupraleitern und einem beruehrungslos arbeitenden Linearantriebssystem am Beispiel eines Demonstrators entwickelt. Der voellig beruehrungslos und damit reibungs- und abriebfrei funktionierende Lift ist fuer Anwendungen in Reinraeumen z.B. in der Mikroelektroniktechnologie praedestiniert. (orig.)

    The explanations, which have been given in the talk are supposed to reveal, that the aim of the marketing for electric-powered vehicles is not to carry the idea of environmental protection into the society. It is far more important to use the power of the present environmental consciousness in order to guarantee the consumers demands for mobility, taking into consideration the ecological interests. (orig.) [Deutsch] Die vorstehenden Ausfuehrungen sollten insbesondere deutlich machen, dass das Ziel eines Marketing fuer E-Mobile nicht darin bestehen kann, den Umweltschutzgedanken in die Gesellschaft zu tragen. Vielmehr geht es darum, die Schubkraft vorhandenen Umweltbewusstseins dafuer zu nutzen, Mobilitaetsbeduerfnisse von Konsumenten unter Bewahrung oekologischer Interessen sicherzustellen. (orig.)

    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.

    In the course of the integration of the customer Langnese Iglo in autumn 1997 and in view of the already existing general conditions for the implementation of the equlations of the directive on food hygiene (HACCP-concept) as well as the permanently in reasing demand for quality of logistics DANZAS Logistics GmbH, cooperating closely with in deep-frozen goods customer Langnese-Iglo decided to develop a new system of quality assurance for the transportation of deep-frozen goods and apply this system to all its activities. First ideas about standard demands, technical solutions and multi-functional design showed that the project had to be handled in such a flexible way that temperature controlling (for the transportation of deep-frozen goods, temperature-controlled DANZAS-warehouses and all future temperature-controlled transportation) and the monitoring of security-relevant transportation can be integrated in one and the same project. (orig.) [German] Im Zuge der Integration des Kunden Langnese Iglo im Herbst 1997 und unter Beruecksichtigung der bereits vorliegenden Rahmenbedingungen zur Umsetzung der Bestimmungen der Lebensmittelhygieneverordnung (HACCP-Konzept) sowie des staendig wachsenden Qualitaetsanspruches an logistische Dienstleistungen, hat sich die DANZAS Logistics GmbH in enger Zusammenarbeit mit dem TK-Kunden Langnese Iglo entschlossen, ein innovatives System zur Qualitaetssicherung im Tiefkuehltransport zu erarbeiten und flaechendeckend einzusetzen. Die ersten Gedanken bezueglich Standardanforderungen, technischer Loesungsansaetze und multifunktionaler Ausrichtung zeigten, dass dieses Projekt so variabel zu gestalten ist, dass sowohl Temperaturcontrolling (fuer TK-Transporte, fuer die temperaturgefuehrten DANZAS-Laeger und zukuenftig alle temperaturgefuehrten Transporte) als auch die Ueberwachung sicherheitsrelevanter Transporte zu integrieren sind.

    The article explains to what extent suitable measures can be realized and supported in a municipality with municipal energy concepts or even climate protection concepts. The target is to attain with limited financial means the most favourable economic and ecological effects in the municipality or in the region. Many electric utilities have in the last years forced the realization of energy conservation measures and have become energy service companies. With their expert knowledge they are ideal partners for politics, public adminstration and citizens. They have the best qualificatons for the development and realization of municipal concepts. In many cases it shows that with detailed studies the target can be quicker and more effectively attained as with extensive, time-consuming and expensive studies which are not particularly realization-oriented. The report is to give examples which might be helpful for the development of a concept. (orig./UA) [Deutsch] Der Beitrag erlaeutert, inwieweit umfangreiche kommunale Energiekonzepte oder sogar Klimaschutzkonzepte geeignete Massnahmen in der Kommune realisieren und foerdern koennen. Ziel sollte sein, mit begrenztem Mitteleinsatz die oekonomisch-oekologisch groessten Effekte in der Kommune bzw. in der Region zu erzielen. Viele Energie-Versorgungsunternehmen haben in den letzten Jahren die Realisierung von Energieparmassnahmen vorangetrieben und sich zu Energie-Dienstleistungsunternehmen entwickelt. Mit ihrer Sachkompetenz sind sie der ideale Partner fuer Politik, oeffentliche Verwaltung und Buerger/innen. Sie bringen die besten Voraussetzungen mit bei der Erarbeitung und Umsetzung von kommunalen Konzepten. Vielfach zeigt sich, dass Detailkonzepte schneller und wirkungsvoller zum Ziel fuehren, als umfachreiche, zeitaufwendige und teure Studien, die wenig umsetzungsorientiert sind. Die nachfolgenden Ausfuehrungen sind als Beispiele gedacht. Sie koennen Anregungen fuer die Erstellung eines Konzeptes vermitteln. (orig./UA)

    The value of macromolecular contrast agents (MMCM) for the characterization of benign and malignant breast tumors will be demonstrated in this review. Animal studies suggest a high potential of MMCM to increase the specificity of MR-mammography. The concept of tumor differentiation is based on the pathological hyperpermeability of microvessels in malignant tumors. MMCM show a leak into the interstitium of carcinomas, whereas they are confined to the intravascular space in benign tumors. Capabilities and limitations of the MMCM-prototype. Albumin-Gd-DTPA, for breast tumor characterization will be summarized and compared to the standard low molecular weight contrast agent Gd-DTPA. Initial experience with new MMCM, such as Dendrimers, Gd-DTPA-Polylysine and MS-325 will be outlined. The potential of `blood-pool`-iron oxides, such as AMI-227 for the evaluation of tumor microvascular permeabilities will be discussed. (orig.) [Deutsch] Diese Uebersicht stellt den Stellenwert makromolekularer Kontrastmittel (MMKM) fuer die MR-tomographische Charakterisierung von benignen und malignen Mammatumoren dar. Aufgrund experimenteller Studien lassen MMKM eine signifikante Verbesserung der Spezifitaet der dynamischen kontrastmittelunterstuetzten MR-Mammographie erwarten. Das differentialdiagnostische Konzept beruht auf der pathologischen Hyperpermeabilitaet von Kapillaren in Karzinomen, die einen MMKM-Austritt in das Tumorinterstitium bedingt, waehrend die intakten Kapillaren benigner Tumoren nicht permeabel fuer MMKM sind. Diagnostische Moeglichkeiten und Grenzen des MMKM-Prototyps, Albumin-Gd-DTPA (92 kD), werden dargestellt und mit dem niedermolekularen Standard-Kontrastmittel Gd-DTPA (500 D) verglichen. Erste Erfahrungen mit neuen, fuer die klinische Anwendung optimierten MMKM-Praeparaten, wie das Kaskadenpolymer, Gd-DTPA-Polylysine und das MS-325 werden vorgestellt.

    The Chair in the Theory of Mining Methods and Operations (Deep Mines) at the Institute for Mining at Clausthal Technological University deals with the theory of and research into underground extraction of solid mineral raw materials. With the concentration and concentration of the German mining industry the department has focussed more attention on foreign mining industries and utilisation of the earth's crust in general. The extractive mining industry is augmented by the underground utilisation of cavities for disposal purposes and for infrastructural tasks. Accordingly the courses offered have been extended towards environmental protection and geotechnics. In particular basic research in the field of disposal in mines has become one of the main areas of research in the department not least of all because of the financing from public funds. Theory, research and further training now cover underground extraction in mines, disposal in mines and rehabilitation of contaminated industrial sites. (orig.)

Calculations are made for the El Nino phenomenon, NAO, and the quasi-11-year cycle of solar radiation variation. Especially the El Nino calculations show the efficiency of PCPA. [German] Mit Hilfe der Principal Correlation Pattern Analysis (PCPA) koennen die von verschiedenen Klimaantrieben erzeugten lokalen Zirkulations-, Temperatur- und Niederschlagsanomalien auf der Nordhemisphaere in monatlicher Aufloesung dargestellt und ursaechlich interpretiert werden. Diese Rechnungen wurden fuer das El Nino Phaenomen, die NAO und den quasi 11-jaehrigen Zyklus der solaren Strahlungsschwankungen durchgefuehrt. Insbesondere die Untersuchungen zu Wirkungen von El Nino auf Europa zeigen, dass die PCPA die Kopplungen eines Prozesses mit dem Klimasystem sehr genau beschreibt und somit die Voraussetzungen schafft, die Wirkungen dieses Klimaantriebs zu modellieren und ihn zur Vorhersage zu nutzen. Erste einfache Vorhersageexperimente fuer das europaeische Klima bestaetigen diese Aussage. (orig.)

    The continuing rise in cost pressure calls for measures for enhancing the efficiency of operation management and maintenance. At the same time it is necessary to maintain the requisite reliability of production and keep abreast of the ever more stringent requirements of working safety and environment protection. This paper presents an integral operation management system for production plants which does justice to both the productive and the and the conserving function of operation management. The development and introduction of this system to conventional power plants has meanwhile begun. The system consistently gives consideration to the fact that operation management depends on processing data and information of different properties. Whereas process data can show strong fluctuations, there are many kinds of information on the plant concerning, for example, plant installations, processes, damage, and maintenance which hardly fluctuate at all or only change over long time periods. These latter include plant and installation addresses, technical data on the system or on maintenance. In operation management systems designed for production plants it can therefore be useful to organise the handling of process data (dynamic data) and plant data (static data) separately. [Deutsch] Der immer staerkere Kostendruck erfordert Massnahmen zur Effizienzsteigerung der Betriebsfuehrung und der Instandhaltung bei Erhaltung der erforderlichen Zuverlaessigkeit der Produktion, steigenden Anforderungen an Arbeitssicherheit und Umweltschutz. Ein Gesamtbetriebsfuehrungssystem, das sowohl die Produktionsfunktion, als auch die Erhaltungsfunktion abdeckt, wurde fuer Produktionsanlagen konzipiert. Fuer konventionelle Kraftwerke wurde die Entwicklung und Einfuehrung begonnen. Dieses System beruecksichtigt konsequent, dass bei der Betriebsfuehrung Daten und Informationen mit unterschiedlichen Eigenschaften zu verarbeiten sind. Waehrend die Prozessdaten hoch fluktuierende Daten sein koennen

    Knittings based on ceramic filament yarns can be used to clean polluted air and exhaust gas efficiently up to temperatures of 1000 C. They provide interesting properties for the filtration of Diesel particles as well as for catalysis and adsorption of toxic gas components. The special knitting technology can handle any brittle fibers, producing elastic structures, which are thermochoc-resistent and can therefore even be used for preturbo applications. The first part of this paper, published in MTZ 56 (1995) 2 deals with the basic properties of this cleaning medium. This second part concentrates on Diesel particulate trop applications. These new trap and catalyst concepts are under development by Buck/Bondorf with TTM/Niederrohrdorf. Basic research is delegated to ETH Zuerich and Universitaet by Gillet/Edenkoben and, with focus on preturbo-applications by MTU/Friedrichshafen. (orig.) [Deutsch] Gestricke aus keramischen Endlosfasern sind bis zu Temperaturen um 1000 C fuer die Abluft- und Abgasreinigung einsetzbar. Sie eignen sich fuer die Filtration von Dieselpartikeln, insbesondere deren Feinstfraktionen ebenso wie fuer die Katalyse und fuer die Adsorption gasfoermiger Schadstoffkomponenten. Die Strukturen sind volumenelastisch, unempfindlich gegen Thermoschock und daher auch im motornahen Bereich risikoarm einsetzbar. In einem ersten Teilbeitrag in der Februarausgabe der MTZ wurden grundlegende Erkenntnisse dieses Abgasreinigungsmediums beschrieben. Der vorliegende zweite Teil beschreibt Anwendungen mit Schwerpunkt Dieselpartikelfilter. Diese neue Fasertechnik wird bei Buck, Bondorf, zusammen mit TTM, Niderrohrdorf, entwickelt. Forschungsarbeiten werden an der ETH Zuerich und der Universitaet Erlangen im Rahmen des BMFT-Projektes 01 VQ 9305/9 durchgefuehrt. Fragen zu motornachgeschalteten Anwendungen untersucht Gillett, Edenkoben, Moeglichkeiten der Motorintegration solcher Filter die MTU Friedrichshafen. (orig.)

    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.

  11. An Abstract Model of Historical Processes

    Directory of Open Access Journals (Sweden)

    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.

    This book presents new accurate and efficient exponentially convergent methods for abstract differential equations with unbounded operator coefficients in Banach space. These methods are highly relevant for the practical scientific computing since the equations under consideration can be seen as the meta-models of systems of ordinary differential equations (ODE) as well as the partial differential equations (PDEs) describing various applied problems. The framework of functional analysis allows one to obtain very general but at the same time transparent algorithms and mathematical results which

    2003-10-01

    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. Bis heute gelten vollstaendig bleifreie Loesungen fuer hochbelastete Gleitlager als technisch nicht machbar. Deshalb nennt die europaeische Altautoverordnung (2000/53/EG), die seit dem 1. Juli 2003 in Kraft ist, als Ausnahme die kupferbasierten Bleibronzelager. Die Gleitlagergruppe von Federal-Mogul hat jetzt ihren Rueckzug aus der Verarbeitung von Blei angekuendigt und geht das Thema Schicht fuer Schicht an. Ein kuerzlich eingefuehrtes, anpassungsfaehiges Lager fuer High-End-Verbrennungsmotoren verfuegt ueber eine bleifreie Laufschicht. Bei diesem neuen Lager veraendern sich die technischen Eigenschaften waehrend der Einlaufphase. (orig.)

    The renaissance of carbon dioxide in refrigeration engineering is impressive. The contribution shows that the disadvantages of this refrigerating fluid can be compensated by modifying the refrigeration circuit. A combined expander-compressor working by the free piston principle and developed at Dresden Technical University is described. [German] Kohlendioxid erlebt im Bereich der Kaeltetechnik infolge der schwierigen Suche nach umweltvertraeglichen Ersatzkaeltemitteln fuer die Fluorchlorkohlenwasserstoffe eine beeindruckende Renaissance. Es soll anhand thermodynamischer Prozessberechnungen gezeigt werden, dass durch die Modifikation des Kreisprozesses unter Beachtung der besonderen thermodynamischen Eigenschaften des Kohlendioxids diese Nachteile bereits bei der theoretischen Leistungszahl ausgeglichen werden koennen. Dafuer wird das Kohlendioxid in einem Prozess mit zweistufiger Verdichtung arbeitsleistend entspannt. Die Besonderheit dieses Prozesses ist die Verwendung einer speziell fuer diesen Anwendungsfall entwickelten Maschine, die die gewonnene Expansionsarbeit direkt fuer die Verdichtung des Kohlendioxids in der zweiten Verdichtungsstufe nutzt. Es handelt sich dabei um eine nach dem Freikolbenprinzip arbeitende Expansions-Kompressions-Maschine, die an der TU Dresden entwickelt und gegenwaertig getestet wird. (orig.)

    The work concerns the task of control described as dispatching of extensive energy supply and distribution networks. Due to the special contractual situation, there are special long-term targets in firms, which must be achieved in addition to the extensive operational tasks of control and monitoring of the networks. The concepts introduced in the work offer a framework for a target-orientated design of computer-aided menus for this superior process control in the energy industry. (orig./GL) [Deutsch] Die Arbeit betrachtet die als Dispatching bezeichnete Aufgabe der Fuehrung ausgedehnter Energieversorgungs- und verteilungsnetze. Aus den speziellen Vertragssituationen ergeben sich in den Unternehmen besondere, langfristige Zielvorgaben an die mit der Betriebsfuehrung beauftragen Operateure, die zusaetzlich zu den umfangreichen operativen Aufgaben der Fuehrung und Ueberwachung der Netze zu erreichen sind. Die in der Arbeit vorgestellten Konzepte bieten den Rahmen fuer einen zielgerichteten Entwurf rechnergestuetzter Hilfsmittel fuer diese uebergeordnete Prozessfuehrung in der Energiewirtschaft. Das erstellte Gesamtsystem wird abschliessend zur Loesung einer konkreten, energiewirtschaftlichen Problemstellung eingesetzt. Die entwickelte Anwendungsloesung wird als Hilfsmittel fuer die technische und vertragliche Optimierung im Dispatching eingesetzt. Wesentliche Zielsetzung ist ein technisch und wirtschaftlich optimaler Einsatz von Energiespeichern zur Deckung von Spitzenlasten. (orig./GL)

    2003-07-01

    The report presents a summary of the project of the above title (EFAS project). 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. [German] Der Bericht fasst die Ergebnisse des Projektes ''Einsatzszenarien fuer Fahrerassistenzsysteme im Gueterverkehr'' (EFAS) zusammen. Bisher wurde die Thematik Fahrerassistenzsysteme hauptsaechlich auf der Seite der Fahrzeugtechnik vorangetrieben. Das Projekt EFAS stellt nun zum ersten Mal eine umfassende Analyse, Darstellung und Bewertung dar. Mit Hilfe einer systemischen Analyse werden die wesentlichen Einflussfaktoren fuer die Einbindung von Fahrerassistenzsystemen in das Gesamtsystem ''Verkehr'' bestimmt und untersucht. Hieraus werden drei Einsatzszenarien entwickelt, die nutzerbezogene, organisatorische, betriebliche, fahrzeugtechnische, infrastukturelle und rechtliche Aspekte zu Zukunftsbildern zusammenfuegen. Die Szenarien werden mit Hilfe von Fahr- und Verkehrssimulationen in den Bereichen Mensch, Organisation und Technik bewertet. Aus den Ergebnissen werden konkrete Handlungsempfehlungen fuer den Einsatz von Fahrerassistenzsystemen im Strassengueterverkehr abgeleitet. (orig.)

  5. 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

    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.

    Embodiment theory proposes that neural systems for perception and action are also engaged during language comprehension. Previous neuroimaging and neurophysiological studies have only been able to demonstrate modulation of action systems during comprehension of concrete language. We provide neurophysiological evidence for modulation of motor system activity during the comprehension of both concrete and abstract language. In Experiment 1, when the described direction of object transfer or information transfer (e.g., away from the reader to another) matched the literal direction of a hand movement used to make a response, speed of responding was faster than when the two directions mismatched (an action-sentence compatibility effect). In Experiment 2, we used single-pulse transcranial magnetic stimulation to study changes in the corticospinal motor pathways to hand muscles while reading the same sentences. Relative to sentences that do not describe transfer, there is greater modulation of activity in the hand muscles when reading sentences describing transfer of both concrete objects and abstract information. These findings are discussed in relation to the human mirror neuron system.

    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

    In this work, supply curves for 22 major oil producing countries were identified and then aggregated into global supply curves. According to the identified supply curves, almost all oil-producing oil projects currently under development in the study countries are also profitable at the current oil price of $ 35 to $ 40 per barrel, taking short-term marginal costs into account. However, if the price of oil remains at this level in the coming years, a supply bottleneck on the global oil market will occur until 2024, as the development of cost-intensive, unconventional deposits and of deposits in deep and very deep waters is necessary to meet future demand. In order to avoid such a supply bottleneck by 2024, an oil price of at least US $ 80 per barrel is required, according to the long-term market equilibrium determined. [German] In dieser Arbeit wurden Angebotskurven fuer 22 bedeutende Oelfoerderlaender ermittelt und anschliessend zu globalen Angebotskurven aggregiert. Gemaess den ermittelten Angebotskurven sind nahezu alle gegenwaertig in der Foerderphase befindlichen Oelprojekte in den Untersuchungslaendern auch beim aktuellen Oelpreis von 35 bis 40 US-$ je Barrel unter Beruecksichtigung der kurzfristigen Grenzkosten rentabel. Sollte der Oelpreis jedoch in den kommenden Jahren auf diesem Niveau verharren, wird es bis zum Jahr 2024 zu einem Angebotsengpass auf dem globalen Oelmarkt kommen, da zur Deckung der zukuenftigen Nachfrage die Erschliessung kostenintensiver, unkonventioneller Lagerstaetten und von Lagerstaetten in tiefen und sehr tiefen Gewaessern notwendig ist. Damit es bis zum Jahr 2024 nicht zu einem solchen Angebotsengpass kommt, ist gemaess des ermittelten langfristigen Marktgleichgewichts ein Oelpreis von mindestens 80 (2014er) US-$ je Barrel notwendig.

After the introduction of initial products onto the market, corresponding requirements for plants based on this new technology should be specified. (orig.) [German] Beim vorliegenden Gutachten handelt es sich um eine Machbarkeitsstudie nach ISO 14024. 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. Als moegliche Umschrift eines Zeichens fuer kleine BHKW-Module wird empfohlen: 'Umweltzeichen... weil energieefizient'. Neben motorischen BHKW wurden auch kleine Brennstoffzellen-BHKW untersucht. Diese befinden sich zur Zeit noch in einer Feldtest- und Erprobungsphase. Sie weisen deutliche oekologische

  13. Physical and Chemical Environmental Abstraction Model

    Nowak, E.

    2000-01-01

    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

  14. Is the Abstract a Mere Teaser? Evaluating Generosity of Article Abstracts in the Environmental Sciences

    Full Text Available An abstract is not only a mirror of the full article; it also aims to draw attention to the most important information of the document it summarizes. Many studies have compared abstracts with full texts for their informativeness. In contrast to previous studies, we propose to investigate this relation based not only on the amount of information given by the abstract but also on its importance. The main objective of this paper is to introduce a new metric called GEM to measure the “generosity” or representativeness of an abstract. Schematically speaking, a generous abstract should have the best possible score of similarity for the sections important to the reader. Based on a questionnaire gathering information from 630 researchers, we were able to weight sections according to their importance. In our approach, seven sections were first automatically detected in the full text. The accuracy of this classification into sections was above 80% compared with a dataset of documents where sentences were assigned to sections by experts. Second, each section was weighted according to the questionnaire results. The GEM score was then calculated as a sum of weights of sections in the full text corresponding to sentences in the abstract normalized over the total sum of weights of sections in the full text. The correlation between GEM score and the mean of the scores assigned by annotators was higher than the correlation between scores from different experts. As a case study, the GEM score was calculated for 36,237 articles in environmental sciences (1930–2013 retrieved from the French ISTEX database. The main result was that GEM score has increased over time. Moreover, this trend depends on subject area and publisher. No correlation was found between GEM score and citation rate or open access status of articles. We conclude that abstracts are more generous in recent publications and cannot be considered as mere teasers. This research should be pursued

  15. Tailored model abstraction in performance assessments

    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

  18. VEST: Abstract vector calculus simplification in Mathematica

    Squire, J.; Burby, J.; Qin, H.

    2014-01-01

    We present a new package, VEST (Vector Einstein Summation Tools), that performs abstract vector calculus computations in Mathematica. Through the use of index notation, VEST is able to reduce three-dimensional scalar and vector expressions of a very general type to a well defined standard form. In addition, utilizing properties of the Levi-Civita symbol, the program can derive types of multi-term vector identities that are not recognized by reduction, subsequently applying these to simplify large expressions. In a companion paper Burby et al. (2013) [12], we employ VEST in the automation of the calculation of high-order Lagrangians for the single particle guiding center system in plasma physics, a computation which illustrates its ability to handle very large expressions. VEST has been designed to be simple and intuitive to use, both for basic checking of work and more involved computations.

    1992-03-01

    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
