Qualification tests for ITER TF conductors in SULTAN

International Nuclear Information System (INIS)

Bruzzone, P.; Stepanov, B.; Wesche, R.

2009-01-01

From February 2007 to May 2008, 18 short length conductor sections have been tested in SULTAN for design verification and manufacturer qualification of the ITER Toroidal Field (TF) conductor. The test program is focussed on the current sharing temperature, T cs , at the nominal operating conditions, 68 kA current and 11.15 T effective field, which can be fully reproduced in the SULTAN test facility. A broad range of results was observed, with over 2 K difference among the T cs of the conductors. In average, the results are poorer compared to the potential performance estimated from the strand scaling law. The key parameters to mitigate the degradation are not yet clearly identified. The experimental challenges to test conductors with performance degradation are highlighted, including enhanced instrumentation sets, the application of gas flow calorimetry to sense the current sharing power and the post-processing of voltage data to cancel the transverse potential across the cable. The updated schedule of the tests in SULTAN is presented with the short-term action plan for conductor test.

The third phase of upgrading of the superconductor test facility SULTAN into a split coil system (SULTAN III) is in progress. SULTAN III a join project of ENEA (Italy) and PSI (Switzerland) consists of two coil packages, each containing three concentrically mounted superconducting solenoids. Together they will produce a field of nearly 12T between the two coil packages, inside a solenoid bore of 58 cm. The outermost 6T coils have NbTi conductors, whereas the inner 9T and 12T coils are made of A-15 cables. All Nb 3 Sn coils are manufactured by the react-and-wind technique. The split coil arrangement, in connection with a sophisticated sample insert containing a 50 kA superconducting transformer, will allow testing of short samples of high current carrying superconductors, e.g. for fusion applications. The sample insert was designed to allow changing the samples within a few hours without warming up the whole magnet system. This paper deals with the present status and potential of the Split Coil Test Facility SULTAN III

2017-10-01

Buton Sultanate Cityscape was constituted of man-made landscape constructed in the era of Buton Sultanate in 1322. It is one of the Indonesian heritage networks proposed to be the world heritage city. The Sultanate cityscape should have the concept of traditional city and refer to the ecological principles. This research was conducted to analyze elements and spatial patterns of Sultanate cityscape based on the ecological principles (eco-design). Descriptive method was utilized in the research by conducting in-depth interviews with the local custom figures and experts of the local culture, literature reviews, and field observations. The main elements of Buton Sultanate Cityscape consisted of palaces, city square, mosque, cemeteries, and settlements, while the supporting elements located outside the city border include mountains, valleys, rivers, and forests. City square is located in the city center surrounded by the palace, cemetery, and mosque. The main pattern of city circulation pattern has formed a simple figure of human body. Ecological principles can be examined from the housing layout paralleled to the road, direction of most city gates facing the east and forests, and the city wall pattern which is closely related to the religious matter.

Full Text Available Background: Sultanate of Oman is geographically situated in south-west of Asia, having common borders on western side by the land with United Arab Emirates, Saudi Arabia and Yemen and with the Arabian Sea and the Gulf of Oman in the east and the north respectively. The country enjoys one of the best health care facilities including blood transfusion services in the region. Study design: Information was collected through informal personal interviews, digging out the past records, and the report presentations at various forums. Results: A modest start by providing blood units through import, the country is now self-reliant on procuring blood units from voluntary non-remunerate blood donors within the sultanate. A steady growth of blood banks is witnessed in every aspect of blood banking including blood collection, blood processing and supply. Various modalities are adapted in promoting voluntary blood donation programme. Conclusion: Sultanate of Oman has created one of the best blood transfusion services in the region in providing safe blood for transfusion through voluntary donation, a use of blood components and irradiating blood products.

Urban DEM generation, analysis and enhancements using TanDEM-X

Rossi, Cristian; Gernhardt, Stefan

2013-11-01

This paper analyzes the potential of the TanDEM-X mission for the generation of urban Digital Elevation Models (DEMs). The high resolution of the sensors and the absence of temporal decorrelation are exploited. The interferometric chain and the problems encountered for correct mapping of urban areas are analyzed first. The operational Integrated TanDEM-X Processor (ITP) algorithms are taken as reference. The ITP main product is called the raw DEM. Whereas the ITP coregistration stage is demonstrated to be robust enough, large improvements in the raw DEM such as fewer percentages of phase unwrapping errors, can be obtained by using adaptive fringe filters instead of the conventional ones in the interferogram generation stage. The shape of the raw DEM in the layover area is also shown and determined to be regular for buildings with vertical walls. Generally, in the presence of layover, the raw DEM exhibits a height ramp, resulting in a height underestimation for the affected structure. Examples provided confirm the theoretical background. The focus is centered on high resolution DEMs produced using spotlight acquisitions. In particular, a raw DEM over Berlin (Germany) with a 2.5 m raster is generated and validated. For this purpose, ITP is modified in its interferogram generation stage by adopting the Intensity Driven Adaptive Neighbourhood (IDAN) algorithm. The height Root Mean Square Error (RMSE) between the raw DEM and a reference is about 8 m for the two classes defining the urban DEM: structures and non-structures. The result can be further improved for the structure class using a DEM generated with Persistent Scatterer Interferometry. A DEM fusion is thus proposed and a drop of about 20% in the RMSE is reported.

A medium- and long-term perspective is required in human resource development to ensure that future needs and demands for oral healthcare are met by the most appropriate health professionals. This paper presents a case study of the Sultanate of Oman, one of the Gulf States with a current population of 3.8 million, which has initiated dental training through the creation of a dental college. The objectives of this paper are first to describe trends in the dental workforce in Oman from 1990 to date and compare the dental workforce with its medical counterparts in Oman and with other countries, and second, to consider future dental workforce in the Sultanate. Data were collected from published sources, including the Ministry of Health (MoH), Ministry of Manpower (MoM), and Ministry of National Economy (MoNE)-Sultanate of Oman; the World Health Organization (WHO); World Bank; and the Central Intelligence Agency (CIA). Dentist-to-population ratios were compared nationally, regionally and globally for medicine and dentistry. Dental graduate outputs were mapped onto the local supply. Future trends were examined using population growth predictions, exploring the expected impact in relation to global, regional and European workforce densities. Population growth in Oman is increasing at a rate of over 2% per year. Oman has historically been dependent upon an expatriate dental workforce with only 24% of the dentist workforce Omani in 2010 (n = 160). Subsequent to Oman Dental College (ODC) starting to qualify dental (BDS) graduates in 2012, there is an increase in the annual growth of the dentist workforce. On the assumption that all future dental graduates from ODC have an opportunity to practise in Oman, ODC graduates will boost the annual Omani dentist growth rate starting at 28% per annum from 2012 onwards, building capacity towards global (n = 1711) and regional levels (Gulf State: n = 2167) in the medium term. The output of dental graduates from Oman Dental College is

Patienten und Methoden: Wir vergleichen 131-Iod- mit 111-In-Pentetreotide-Szintigraphien bei 24 Patienten mit metastasiertem, nicht-medullaeren Schilddruesenkarzinom. Die Befunde wurden mit anderen bildgebenden Verfahren korreliert. Zusaetzlich erfolgten Rezeptor-Autoradiographien bei einem Patienten, eine Octreotide-Behandlung bei einem anderen und die Verabreichung von 90-Y- sowie 111-In-DOTATOC bei zwei weiteren Patienten. Ergebnisse: Bei 8/15 Patienten mit papillaerem oder follikulaerem Schilddruesenkarzinom erwies sich 111-In-Pentetreotide dem 131-I- als unterlegen, bei 1/15 als gleichwertig und bei 6/15 als ueberlegen. Bei 8/9 Patienten mit onkozytaerem Schilddruesenkarzinom zeigten die Metastasen eine 111-In-Pentetreotide-Akkumulation unterschiedlicher Intensitaet, waehrend die 131-I-Szintigraphien hier bis auf eine Ausnahme negativ waren. Im Vergleich mit 201-Tl oder 99m-Tc-Sestamibi erwies sich 111-In-Pentetreotide als gleichwertig oder ueberlegen, aber im Vergleich zum 18-F-FDG-PET zumeist als unterlegen. Die Befunde der 111-In-Pentetreotide-Szintigraphie korrelierten gut mit der Rezeptor-Autoradiographie und der DOTATOC-Akkumulation, nicht dagegen mit dem Behandlungseffekt von `kaltem` Octreotide auf die Schilddruesenkarzinom-Metastasen.

Sultanate of Oman

International Nuclear Information System (INIS)

1992-09-01

The Sultanate of Oman is primarily an oil-based economy and this will continue into the foreseeable future. In 1982 the proven oil reserves were 2.5 billion barrels, but by 1991 this had risen to over 4.3 billion barrels. However, known reserves greatly exceed these exploitable oil reserves and as techniques for extraction improve it is likely that this figure of 4.3 billion will increase. At current rates of extraction there is enough oil to maintain an average production of 700,000 bpd for 20 years. After years of exploration oil was finally discovered in commercial quantities in Oman in 1964 and production began in 1967. The first oil find was made at Yibal followed by the Fahud oil field in 1964 and this remains the largest single discovery yet. (author)

Calorimetric method for current sharing temperature measurements in ITER conductor samples in SULTAN

International Nuclear Information System (INIS)

Bagnasco, M.

2009-01-01

Several Toroidal Field Conductor short samples with slight layout variations have been assembled and tested in the SULTAN facility at CRPP. The measurement campaigns started in 2007 and are still ongoing. The performance of every conductor is expressed in terms of current sharing temperature (T cs ), i.e. the temperature at which a defined electric field, 10 μV/m, is detected in the cable due to the incipient superconducting-to-normal state transition. The T cs at specific operating conditions is the key design parameter for the ITER conductors and is the main object of the qualification tests. Typically, the average electric field is measured with voltage tap pairs attached on the jacket along the conductor. The inability however to explain observed premature voltage developments opened the discussion about possible alternative measuring methods. The He flow calorimetric method is based on the measurement of the resistive power generation in the conductor. It relies on the detection of very small temperature increases along the conductor in steady state operation. The accuracy and the reliability of the calorimetric method in SULTAN are critically discussed, with particular emphasis on the instrumentation requirements and test procedures. The application of the calorimetric method to the recent SULTAN test campaigns is described with its merits and limits. For future tests of ITER conductors in SULTAN, the calorimetric method for T cs test is proposed as a routine procedure.

From 3 to 14 June 1992 Rio de Janeiro was host to the largest conference that had ever taken place up to that point in human history, the United Nations Conference on Environment and Development (UNCED). One major programmatic outcome of the conference was the approval of Agenda 21. This document was signed by 179 states, but it is not binding under international law. Altogether AGENDA 21 comprises 40 chapters. The present paper draws on a selection of these chapters to exemplify the significance of energy production from biomass and its relationship with the goals of Agenda 21. The author has refrained from discussing the issue of climate and energy policy in a wider context, as this matter will undoubtedly already be known to the reader. [German] Zwischen dem 03. und 14.

Als greifbares programmatisches Ergebnis der Konferenz wurde am Ende die Agenda 21 verabschiedet. Sie wurde von 179 Staaten unterzeichnet, ist aber voelkerrechtlich nicht verbindlich. Insgesamt umfasst die Agenda 21 40 Einzelkapitel. Beispielhaft soll anhand einiger Kapitel die Bedeutung und der Zusammenhang zwischen der energetischen Nutzung der Biomasse und den Zielen der Agenda 21 aufgezeigt werden. Bewusst wird hierbei der Themenbereich 'Klima- und Energiepolitik' nicht weiter betrachtet, da dieser Zusammenhang den Teilnehmern sicherlich bekannt ist. (orig.)

Full Text Available Der Beitrag von Manfred Becker lässt sich wohlmeinend als Plädoyer für einen pragmatischen Umgang mit dem AGG lesen. Er möchte Personaler/-innen zeigen, wie die Vorgaben des AGG im Rahmen eines Human Resources Diversity Managements positiv umgesetzt werden können. In weiten Teilen überzeugen die Ausführungen des Autors aber nicht. Gerade die Darstellung der Inhalte des AGG ist stark von seiner skeptischen Grundhaltung gegenüber dessen Zielsetzung geprägt. Auch wenn die Ausführungen zu konkreten Betriebs- und Personalmaßnahmen gelungener sind, stellt dieser Beitrag insgesamt kein überzeugendes und lesenswertes Werk dar.With the best intention, the work by Manfred Becker can be read as a plea for a pragmatic approach to the AGG. He wishes to show personnel how the guidelines of the AGG can be put into practice within the framework of Human Resources Diversity Management. However, the author’s work is often unconvincing. In particular, the presentation of the contents of the AGG is strongly influenced by his skeptical attitude toward its goals. Even when his approach to concrete company and personnel measures is more successful, the book is neither convincing nor a worthwhile read.

After been banished from the sultanate by Amir Jaqmaq, he was imprisoned at a room of the citadel. This room was the place where his escape adventure began. The most important reason for the escape of the young sultan was the rumor arose at the citadel which was concerning with the death edict given by Sultan Jaqmaq. By the incitements of his attendants, he decided to escape from the Citadel of Cairo to save his life. This escape was critically important connected with the uprisings at Syria at that time. Because Amir Tagribirmish, viceroy of Aleppo and Amir Aynal al-Jakamî, viceroy of Damascus, who protested the reign of Sultan Jaqmaq, had leaned to Yusuf. Although Yusuf had just aimed to save his life by escaping from the citadel, the supporters of him, who objected to the reign of Jaqmaq, wanted to embrace this opportunity against the authority. Bu makale 1439 yılında Sultan Barsbay’ın (1422-1437 vasiyetiyle daha henüz 15 yaşındayken tahta çıkarılıp altı ay iktidarda kalan fakat daha sonra öldürülme korkusuyla firar eden Memlûk Sultanı el-Melik el-Azîz Yusuf’un kaçış serüveniyle ilgilidir.

Wesche, Rainer; Herzog, Robert; Bruzzone, Pierluigi

2008-01-01

The relevance of short sample measurements in SULTAN for the prediction of the performance of the coils of the International Thermonuclear Experimental Reactor (ITER) is assessed using the case of the Nb 3 Sn high-field central solenoid model coil (CSMC) conductor, for which both coil performance and short sample SULTAN results (Good Joint (GJ) sample) are available. A least-squares fit procedure, based on a uniform current distribution among the strands and the Durham scaling relations for the field, temperature and strain dependences of the strand J c provides a thermal strain of -0.294% and a degradation factor of approximately 60% for the GJ sample. In the calculation of the voltage along Layer 1A of the CSMC the hoop stress and the variation of the magnetic field in the conductor cross-section were taken into account. The temperature profile, used in the calculations, is based on published temperature profiles and empirical relations between helium inlet and outlet temperatures. A comparison with the GJ results indicates that short sample measurements in SULTAN provide a conservative estimate of the coil performance

ArcticDEM Validation and Accuracy Assessment

ArcticDEM comprises a growing inventory Digital Elevation Models (DEMs) covering all land above 60°N. As of August, 2017, ArcticDEM had openly released 2-m resolution, individual DEM covering over 51 million km2, which includes areas of repeat coverage for change detection, as well as over 15 million km2 of 5-m resolution seamless mosaics. By the end of the project, over 80 million km2 of 2-m DEMs will be produced, averaging four repeats of the 20 million km2 Arctic landmass. ArcticDEM is produced from sub-meter resolution, stereoscopic imagery using open source software (SETSM) on the NCSA Blue Waters supercomputer. These DEMs have known biases of several meters due to errors in the sensor models generated from satellite positioning. These systematic errors are removed through three-dimensional registration to high-precision Lidar or other control datasets. ArcticDEM is registered to seasonally-subsetted ICESat elevations due its global coverage and high report accuracy ( 10 cm). The vertical accuracy of ArcticDEM is then obtained from the statistics of the fit to the ICESat point cloud, which averages -0.01 m ± 0.07 m. ICESat, however, has a relatively coarse measurement footprint ( 70 m) which may impact the precision of the registration. Further, the ICESat data predates the ArcticDEM imagery by a decade, so that temporal changes in the surface may also impact the registration. Finally, biases may exist between different the different sensors in the ArcticDEM constellation. Here we assess the accuracy of ArcticDEM and the ICESat registration through comparison to multiple high-resolution airborne lidar datasets that were acquired within one year of the imagery used in ArcticDEM. We find the ICESat dataset is performing as anticipated, introducing no systematic bias during the coregistration process, and reducing vertical errors to within the uncertainty of the airborne Lidars. Preliminary sensor comparisons show no significant difference post coregistration

Potential Retrofit of Existing Sultan Ismail Parliament Building, Johor to Green Building

Full Text Available The concept of retrofitting an existing building towards green building was introduced to move towards greener development. This paper investigates the benefits of retrofitting an existing building to green building. The potential retrofit of the existing Sultan Ismail Parliament building was also determined and later the elements of the building to be retrofitted were proposed. The Sultan Ismail Parliament building is one of the newest development that serves as the Johor state administrative center under Iskandar Malaysia. Therefore, this paper focuses on whether the existing building has fulfilled all of the green building elements. A set of questionnaire was distributed to the targeted respondents who were the engineers, architects, technicians, staffs and those who were involved in the development of the Sultan Ismail Parliament building. A total of 60 respondents was involved. Based on the analyzed data, it shows that the existing building has fulfilled only one of the green building elements which is the Indoor Environmental Quality. The items that scored 3.5 and above mean index under this element include the daylight glare is not bothering, the ventilation in the building is adequate, inspections are done regularly, smoking regulation is implemented and the number of openings of windows and doors is sufficient. While it shows that other elements were only partially fulfilled. The criteria that achieved below 3.5 mean index values is considered to be the potential elements that could be used for future retrofitting initiative.

In the world's biggest research project, the sick building syndrome was investigated in Germany between 1995 and 1999. In all, 8 air-conditioned buildings and 6 non-air-conditioned buildings, 40 space HVAC systems and 1497 places of work were analyzed, and 4,500 persons were asked to provide data. For the first time ever, measured physical, biological and chemical data were compared with the subjective data provided by the inquiry forms. It was found that the concentrations and hygienic status of air conditioning systems do have an effect on subjective comfort. Buildings with well-designed and well-serviced space HVAC systems had better results than buildings without air conditioning systems. However, it is the psychosocial environment and the job description of building inhabitants that decide their response in terms of sick building syndrome. Factors like gender, job satisfaction, job specifications and educational level are more important than space HVAC systems.

The results yielded by the Variable Flow Model (VFDM) permitted determining water flow velocities and degrees of dispersiveness. It transpired that it is not possible to isolate immobile water, which is to say that the available measuring and modelling data permit no conclusion as to whether or not the system contains immobile water. Comparison with the results obtained with the Dispersion Model (DM) showed that the simpler DM model yields tracer concentration curves in the system output that are almost as good as those of the more complicated VFDM model while entailing less work. The two models yield very similar calculations of lysimeter water content. [Deutsch] Die Ergebnisse der Modellierung mit dem Variable-Flow-Modell (VFDM) ermoeglichten die Bestimmung von Wassergeschwindigkeiten des Wassers und Dispersivitaeten. Es wurde dabei festgestellt, dass eine Abtrennung des immobilen Wassers nicht moeglich ist. D.h. es kann nicht auf Grund vorhandener Messdaten und der Modellierung entschieden werden, ob das System immobiles Wasser beinhaltet oder nicht. Ein Vergleich der Ergebnisse nach dem Variable-Flow- und dem Dispersions-Modell (DM) zeigte, dass das einfache Modell DM mit weniger Aufwand fast so gute Tracerkonzentrationskurven im Output aus dem System liefert wie das komplizierte Modell mit VFDM. Die berechneten Wassergehalte der Lysimeter nach beiden Modellierungen sind sehr aehnlich. (orig.)

Kadir, Abdul; Mahruddin, Mahruddin; Erdianti; Gazali, Mardlina

2018-05-01

This article examines the management of the government system of Buton Sultanate in one philosophy: “Poromu Yinda Saangu, Pogaa Yinda Koolota”. This philosophy is believed to be the unifying of the Buton Sultanate for hundreds of years. This paper is a qualitative descriptive with ethnographic approaches. The results indicate that this philosophy provides insight to the citizens of the Buton sultanate on the importance of relations among elements of government such as Kaomu, Walaka and Papara. These three elements are likened to a human body consisting of Kaomu as Head, the place of the good brain, brightly lit because it always receives the light of Divine Nur. Walaka is as a body; the heart contains a sacred heart because there is a place where the balance of justice is published. Papara as an accomplice has the power of lahiriyah. The relationship of three elements is bound and intertwined in one philosophy: “It is near but untouchable, it is far away, but no space between them”. This implies that all three must unite to uphold justice and common interests, but they should not violate other rights. Therefore, this philosophy can be used as the central management system to build good governance.

Full Text Available Das vorgeschlagene Thema hat das Ziel, dem Konzept der Landschaft eine neue Definition zu geben. Sie soll nicht nur als Umhuellung des staedtischen und laendlichen Territoriums gesehen werden, das besiedelt und produktiv ist, zivilisiet und natuerlich belassen, sondern wie ein lebender Koerper, wenn auch nicht bei bester Gesundheit, der trotz seines Altes noch den vielen Veraenderungen standhaelt. Veraenderungen durch Naturkatatrophen herforgerufen, und besonders durch die vielen Wunden die das Werk der Menschen ihm zugefuegt hat. Als lebendes Wesen leidet die Landschaft und freut sich in guten Zeiten, kleidert sich lieber arm, aber schicklich, als reich und anmassend: Zeuge guter und schlechter Haushaltsfuehrung, jedoch Erbe einer Geschichte die sie erhebt, die Geschichte, Literatur, Ausdruecke der Kunts, kreative Planung beseelt hat. All das ist zusammengefasst in dem Wort "Kultur", die es verdient hat, erworben zu werden, vertieft und den naeschsten Generationen weitergegeben, moeglicherweise noch bereichert von dem, das die heutige Kultur ausarbeiten kann, auch auf dem Weg der Stadtplanung.

Digital elevation models (DEM) are an important source of information on the terrain, allowing researchers to evaluate various exogenous processes. The higher the accuracy of DEM the better the level of the work possible. An important source of data for the construction of DEMs are point clouds obtained with terrestrial laser scanning (TLS) and unmanned aerial vehicles (UAV). In this paper, we present the results of constructing a DEM on small catchments using UAVs. Estimation of the UAV DEM showed comparable accuracy with the TLS if real time kinematic Global Positioning System (RTK-GPS) ground control points (GCPs) and check points (CPs) were used. In this case, the main source of errors in the construction of DEMs are the errors in the referencing of survey results.

Eisenblätter, Andreas; Geerdes, Hans-Florian

Wer hat das noch nicht erlebt? Der Akku ist aufgeladen und reichlich Guthaben vorhanden, doch das Telefonieren mit dem Handy klappt trotzdem nicht. Meist liegt das daran, dass man sich in einem Funkloch befindet. Aber manchmal ist auch das Netz überlastet. Anders gesagt: das Funknetz des Mobilfunkanbieters, das viele Antennen auf Hausdächern oder Masten umfasst, bietet entweder nicht genügend Abdeckung oder nicht genügend Kapazität. Genau das will der Anbieter natürlich vermeiden. Mathematik hilft, diese Herausforderungen mit einer guten Planung des Mobilfunknetzes zu bewältigen.

Full Text Available This article describes and analyzes the first diplomatic gift presented by the States General of the Netherlands to the Ottoman Sultan Ahmet I in 1612/1613. The extensive and very costly assortment of items was presented to the Sultan in gratitude for capitulations, permitting the Dutch access to Ottoman ports and therefore direct access to trade in the Levant and Mediterranean. This paper describes the diplomatic gift, a long-neglected episode in Dutch material cultural history, and looks in particular at the role that wonder and wonders played in structuring this remarkable encounter between the fledgling Dutch Republic and the Ottoman court.

Electric power is not the same power. Why the energy transition can not succeed; Strom ist nicht gleich Strom. Warum die Energiewende nicht gelingen kann

Limburg, Michael; Mueller, Fred F.

2015-07-01

The energy transition - the conversion of our power supply to so-called ''Renewable Energy'' - will lead to disaster, economically as well as technically. Although the concept is not technically feasible, more than 500 billion Euros were spent for this purpose already. This money our economy will miss bitterly when it is needed it to go, sweep up the future shambles. Here explain two recognized experts why. ''The book, 'electric power is not the same power' pulled himself together again on a colossal effort. It dissects technically brilliant with the tools of logic, scientific reasoning a fatal mental aberration.''- Arnold Vaatz MP. [German] Die Energiewende - die Umstellung unserer Stromversorgung auf sogenannte ''Erneuerbare Energien'' - wird in eine Katastrophe fuehren, wirtschaftlich ebenso wie technisch. Obwohl das Konzept technisch nicht machbar ist, wurden hierfuer bereits mehr als 500 Milliarden Euro ausgegeben. Dieses Geld wird unserer Volkswirtschaft bitter fehlen, wenn sie darangehen muss, den kuenftigen Scherbenhaufen zusammenzukehren. Hier erklaeren zwei ausgewiesene Fachleute, warum. ''Das Buch 'Strom ist nicht gleich Strom' rafft sich noch einmal zu einer ungeheuren Kraftanstrengung auf. Es seziert handwerklich brillant mit den Mitteln der logischen, naturwissenschaftlichen Argumentation einen fatalen geistigen Irrweg.'' - Arnold Vaatz MdB.

Experiments have shown that the Luenen plant can be operated with animal meal as mono-fuel. In fact, combustion characteristics will be better and emissions lower. The ash has an excellent burnout. It contains no proteins, so it appears reasonable to assume that any prions will be destroyed during combustion. [German] Auf Basis der bestehenden Betriebserfahrungen ist die ZWS in Luenen technisch nachweislich in der Lage, 100% der Feuerungswaermeleistung ueber Tiermehl abzudecken. Damit ist ein Betrieb als Monobrennstoffanlage durchfuehrbar. Besonders erfreulich ist zu werten, dass sich bei dem Einsatz von Tiermehl das Verbrennungsverhalten der Anlage positiver darstellt und eine Verbesserung der Emissionssituation auftritt. Die entstehende Asche weist einen ungewoehnlich guten Ausbrand auf. In ihr sind Proteine nicht mehr nachweisbar und daraus kann rueckgeschlossen werden, dass in der ZWS auch potentiell Prionen vernichtet werden. (orig.)

Estimating Coastal Digital Elevation Model (DEM) Uncertainty

Science.gov (United States)

Amante, C.; Mesick, S.

2017-12-01

Integrated bathymetric-topographic digital elevation models (DEMs) are representations of the Earth's solid surface and are fundamental to the modeling of coastal processes, including tsunami, storm surge, and sea-level rise inundation. Deviations in elevation values from the actual seabed or land surface constitute errors in DEMs, which originate from numerous sources, including: (i) the source elevation measurements (e.g., multibeam sonar, lidar), (ii) the interpolative gridding technique (e.g., spline, kriging) used to estimate elevations in areas unconstrained by source measurements, and (iii) the datum transformation used to convert bathymetric and topographic data to common vertical reference systems. The magnitude and spatial distribution of the errors from these sources are typically unknown, and the lack of knowledge regarding these errors represents the vertical uncertainty in the DEM. The National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Information (NCEI) has developed DEMs for more than 200 coastal communities. This study presents a methodology developed at NOAA NCEI to derive accompanying uncertainty surfaces that estimate DEM errors at the individual cell-level. The development of high-resolution (1/9th arc-second), integrated bathymetric-topographic DEMs along the southwest coast of Florida serves as the case study for deriving uncertainty surfaces. The estimated uncertainty can then be propagated into the modeling of coastal processes that utilize DEMs. Incorporating the uncertainty produces more reliable modeling results, and in turn, better-informed coastal management decisions.

Full Text Available The coming of Islam in the Buton Sultanate has brought a change in the social, political, even in the intellectual aspects. It produced scholars with the thought or ijitihad as a blend of Islamic and local cultures. One of the scholars as well as Buton Sultan was Muhammad Idrus Kaimuddin Ibnu Badaruddin Al Buthuni (1824-1851. His thought or ijitihad found the essence of the concept of manners according to the teachings of the ancestors in kabanti Bula Malino. His several works became the guidance of the public and court authorities in the Sultanate of Buton which were basically rooted from the teachings of Islam. Kaimuddin’s thought in terms of ethics, morals, manners, or advice showed his horizons of knowledge and the depth of leadership thought. The magnitude of Islamic influence in some of his works proves the enduring process of Islamic acculturation done continuously and deeply since the era of Buton Islamic empire. Kaimuddin’s thought is essentially a formation process of Buton’s civilization centered on the palace and passed to Buton society in general through the process of cultural dialogue between Buton culture (Wolio and Islam.

Using radar and lidar data, the aim is to improve 3D rendering of terrain, including digital elevation models (DEM) and estimates of vegetation height and biomass in a variety of forest types and terrains. The 3D mapping of vegetation structure and the analysis are useful to determine the role of forest in climate change (carbon cycle), in providing habitat and as a provider of socio-economic services. This in turn will lead to potential for development of more effective land-use management. The first part of the project was to characterize the Shuttle Radar Topography Mission DEM error with respect to ICESat/GLAS point estimates of elevation. We investigated potential trends with latitude, canopy height, signal to noise ratio (SNR), number of LiDAR waveform peaks, and maximum peak width. Scatter plots were produced for each variable and were fitted with 1st and 2nd degree polynomials. Higher order trends were visually inspected through filtering with a mean and median filter. We also assessed trends in the DEM error variance. Finally, a map showing how DEM error was geographically distributed globally was created.

Full Text Available The TanDEM-X mission will derive a global digital elevation model (DEM with satellite SAR interferometry. Two radar satellites (TerraSAR-X and TanDEM-X will map the Earth in a resolution and accuracy with an absolute height error of 10m and a relative height error of 2m for 90% of the data. In order to fulfill the height requirements in general two global coverages are acquired and processed. Besides the final TanDEM-X DEM, an intermediate DEM with reduced accuracy is produced after the first coverage is completed. The last step in the whole workflow for generating the TanDEM-X DEM is the calibration of remaining systematic height errors and the merge of single acquisitions to 1°x1° DEM tiles. In this paper the current status of generating the intermediate DEM and first validation results based on GPS tracks, laser scanning DEMs, SRTM data and ICESat points are shown for different test sites.

The Importance of Precise Digital Elevation Models (DEM) in Modelling Floods

Science.gov (United States)

Demir, Gokben; Akyurek, Zuhal

2016-04-01

Digital elevation Models (DEM) are important inputs for topography for the accurate modelling of floodplain hydrodynamics. Floodplains have a key role as natural retarding pools which attenuate flood waves and suppress flood peaks. GPS, LIDAR and bathymetric surveys are well known surveying methods to acquire topographic data. It is not only time consuming and expensive to obtain topographic data through surveying but also sometimes impossible for remote areas. In this study it is aimed to present the importance of accurate modelling of topography for flood modelling. The flood modelling for Samsun-Terme in Blacksea region of Turkey is done. One of the DEM is obtained from the point observations retrieved from 1/5000 scaled orthophotos and 1/1000 scaled point elevation data from field surveys at x-sections. The river banks are corrected by using the orthophotos and elevation values. This DEM is named as scaled DEM. The other DEM is obtained from bathymetric surveys. 296 538 number of points and the left/right bank slopes were used to construct the DEM having 1 m spatial resolution and this DEM is named as base DEM. Two DEMs were compared by using 27 x-sections. The maximum difference at thalweg of the river bed is 2m and the minimum difference is 20 cm between two DEMs. The channel conveyance capacity in base DEM is larger than the one in scaled DEM and floodplain is modelled in detail in base DEM. MIKE21 with flexible grid is used in 2- dimensional shallow water flow modelling. The model by using two DEMs were calibrated for a flood event (July 9, 2012). The roughness is considered as the calibration parameter. From comparison of input hydrograph at the upstream of the river and output hydrograph at the downstream of the river, the attenuation is obtained as 91% and 84% for the base DEM and scaled DEM, respectively. The time lag in hydrographs does not show any difference for two DEMs and it is obtained as 3 hours. Maximum flood extents differ for the two DEMs

Precise topographical information has a very important role in geology, hydrology, natural resources survey and deformation monitoring. The extracting DEM technology based on synthetic aperture radar interferometry (InSAR) obtains the three-dimensional elevation of the target area through the phase information of the radar image data. The technology has large-scale, high-precision, all-weather features. By changing track in the location of the ground radar system up and down, it can form spatial baseline. Then we can achieve the DEM of the target area by acquiring image data from different angles. Three-dimensional laser scanning technology can quickly, efficiently and accurately obtain DEM of target area, which can verify the accuracy of DEM extracted by GBInSAR. But research on GBInSAR in extracting DEM of the target area is a little. For lack of theory and lower accuracy problems in extracting DEM based on GBInSAR now, this article conducted research and analysis on its principle deeply. The article extracted the DEM of the target area, combined with GBInSAR data. Then it compared the DEM obtained by GBInSAR with the DEM obtained by three-dimensional laser scan data and made statistical analysis and normal distribution test. The results showed the DEM obtained by GBInSAR was broadly consistent with the DEM obtained by three-dimensional laser scanning. And its accuracy is high. The difference of both DEM approximately obeys normal distribution. It indicated that extracting the DEM of target area based on GBInSAR is feasible and provided the foundation for the promotion and application of GBInSAR.

2018-04-01

ArcticDEM is a collection of 2-m resolution, repeat digital surface models created from stereoscopic satellite imagery. To demonstrate the potential of ArcticDEM for measuring river stages and discharges, we estimate river surface heights along a reach of Tanana River near Fairbanks, Alaska, by the precise detection of river shorelines and mapping of shorelines to land surface elevation. The river height profiles over a 15-km reach agree with in situ measurements to a standard deviation less than 30 cm. The time series of ArcticDEM-derived river heights agree with the U.S. Geological Survey gage measurements with a standard deviation of 32 cm. Using the rating curve for that gage, we obtain discharges with a validation accuracy (root-mean-square error) of 234 m3/s (23% of the mean discharge). Our results demonstrate that ArcticDEM can accurately measure spatial and temporal variations of river surfaces, providing a new and powerful data set for hydrologic analysis.

The study aimed at investigating the conflict management styles used by nurse managers in the Sultanate of Oman. Conflict is inevitable in daily nursing work. Several styles are used to manage conflict situations. In previous studies conducted in Western countries, avoiding and compromising conflict management styles appear to be the first choices for the nurses. In Arab countries, no study to date has examined the conflict management styles used by nurse managers to compare with the results from studies conducted in Western countries. Survey. A questionnaire was distributed to all nurse managers working in the three-management levels from nine referral hospitals in Sultanate of Oman, 271 were returned, a response rate of 86%. The results were analysed using spss version 16. Nurse managers in Oman used all five conflict management styles, with integrating style as the first choice followed in order by compromising, obliging, dominating and avoiding. These results differ from the results of the studies conducted on nurses in other countries. The results of this study have implications for people who work in the hospitals, whether practitioners or policy makers. Recommendations are offered to improve nurse managers' work environment. Conflict can affect patient care if handled badly. Poorly handled conflict results in lower staff morale and poorer retention, both adversely affect patient care. © 2011 Blackwell Publishing Ltd.

The background field of the first phase of the test facility SULTAN will be generated by two concentric solenoids: a 6 Tesla outer coil with a free bore of 1.3 m and an inner coil for increasing the field to 8 Tesla. The free bore (cold) will be 1.055 m. The final design of the 8 Tesla inner coil is described. The coil will operate at an overall current density of 23 x 10 6 A/m 2 . It will be cooled directly by forced flow supercritical helium. A hollow conductor is applied, composed of a rectangular copper tube and a 16 strands Rutherford cable, soldered on one side of the tube. The copper tube will be cold worked to cope with the high stress level (165 MPa). The design base (field and stress analysis, cooling, stability), the mechanical design and the instrumentation will be specified. The design and construction of the coil is a part of the collaboration between ECN and Holec Transformer Group

2014-11-01

The Shuttle Radar Topography Mission (SRTM) data has emerged as a global elevation data in the past one decade because of its free availability, homogeneity and consistent accuracy compared to other global elevation dataset. The present study explores the consistency in hydrological behavior of the SRTM digital elevation model (DEM) with reference to easily available regional 20 m contour interpolated DEM (TOPO DEM). Analysis ranging from simple vertical accuracy assessment to hydrological simulation of the studied Maithon catchment, using empirical USLE model and semidistributed, physical SWAT model, were carried out. Moreover, terrain analysis involving hydrological indices was performed for comparative assessment of the SRTM DEM with respect to TOPO DEM. Results reveal that the vertical accuracy of SRTM DEM (±27.58 m) in the region is less than the specified standard (±16 m). Statistical analysis of hydrological indices such as topographic wetness index (TWI), stream power index (SPI), slope length factor (SLF) and geometry number (GN) shows a significant differences in hydrological properties of the two studied DEMs. Estimation of soil erosion potentials of the catchment and conservation priorities of microwatersheds of the catchment using SRTM DEM and TOPO DEM produce considerably different results. Prediction of soil erosion potential using SRTM DEM is far higher than that obtained using TOPO DEM. Similarly, conservation priorities determined using the two DEMs are found to be agreed for only 34% of microwatersheds of the catchment. ArcSWAT simulation reveals that runoff predictions are less sensitive to selection of the two DEMs as compared to sediment yield prediction. The results obtained in the present study are vital to hydrological analysis as it helps understanding the hydrological behavior of the DEM without being influenced by the model structural as well as parameter uncertainty. It also reemphasized that SRTM DEM can be a valuable dataset for

Full Text Available In this study, LIDAR DEM data was used to obtain a primary landform map in accordance with a well-known methodology. This primary landform map was generalized using the Focal Statistics tool (Majority, considering the minimum area condition in cartographic generalization in order to obtain landform maps at 1:1000 and 1:5000 scales. Both the primary and the generalized landform maps were verified visually with hillshaded DEM and an orthophoto. As a result, these maps provide satisfactory visuals of the landforms. In order to show the effect of generalization, the area of each landform in both the primary and the generalized maps was computed. Consequently, landform maps at large scales could be obtained with the proposed methodology, including generalization using LIDAR DEM.

Niu, Y.; Zhao, C.; Zhang, J.; Wang, L.; Li, B.; Fan, L.

2018-04-01

Due to the systematic error, especially the horizontal deviation that exists in the multi-source, multi-temporal DEMs (Digital Elevation Models), a method for high precision coregistration is needed. This paper presents a new fast DEM coregistration method based on a given SAR (Synthetic Aperture Radar) imaging geometry to overcome the divergence and time-consuming problem of the conventional DEM coregistration method. First, intensity images are simulated for two DEMs under the given SAR imaging geometry. 2D (Two-dimensional) offsets are estimated in the frequency domain using the intensity cross-correlation operation in the FFT (Fast Fourier Transform) tool, which can greatly accelerate the calculation process. Next, the transformation function between two DEMs is achieved via the robust least-square fitting of 2D polynomial operation. Accordingly, two DEMs can be precisely coregistered. Last, two DEMs, i.e., one high-resolution LiDAR (Light Detection and Ranging) DEM and one low-resolution SRTM (Shutter Radar Topography Mission) DEM, covering the Yangjiao landslide region of Chongqing are taken as an example to test the new method. The results indicate that, in most cases, this new method can achieve not only a result as much as 80 times faster than the minimum elevation difference (Least Z-difference, LZD) DEM registration method, but also more accurate and more reliable results.

Highlights: ► RE-123 tapes j c ≥ 500 A/cm (77 K) would enable fusion magnets operating above 20 K. ► Quench studies indicate that the protection of RE-123 fusion magnets is a challenge. ► Possibilities to test 50 kA class HTS conductors in SULTAN have been identified. ► HTS bus bar of large thermal resistance needed to connect sample and NbTi flux pump. ► Tests in the 20–50 K range require additional changes in the SULTAN cryogenics. -- Abstract: In the last few years, the critical current densities of long commercially available REBa 2 Cu 3 O 7−x (RE-123, where RE represents Y or a rare earth element) coated conductors have reached values of 250 A/cm-width at 77 K and zero applied field. Even higher values of 600 A/cm-w (77 K, B = 0) have been demonstrated in shorter lengths. The attractive features of the use of these high-T c superconductors (HTS) are operation temperatures above 20 K and/or magnetic fields higher than those envisaged for the ITER TF coils. Possible operation conditions for HTS fusion magnets have been studied taking into consideration the possible further improvements of RE-123 coated conductors. Investigations of stability and quench behavior indicate that stability is not a problem, whereas quench detection and protection need attention. Because of the high currents necessary for fusion magnets, many tapes need to be assembled into a transposed conductor. The qualification of HTS conductors for fusion magnets would require their test at magnetic fields of 11 T and currents well above 10 kA. The possibilities to test straight HTS conductor samples in SULTAN have been considered. For a test at 4.5 K, only the development of a low resistance joint between the HTS conductor under test and the NbTi transformer of SULTAN would be necessary. Tests up to 20 K would require that the HTS sample is connected with the NbTi transformer by a conduction-cooled HTS bus bar of large thermal resistance similar to the HTS module of a current

Precise baseline determination for the TanDEM-X mission

Science.gov (United States)

Koenig, Rolf; Moon, Yongjin; Neumayer, Hans; Wermuth, Martin; Montenbruck, Oliver; Jäggi, Adrian

The TanDEM-X mission will strive for generating a global precise Digital Elevation Model (DEM) by way of bi-static SAR in a close formation of the TerraSAR-X satellite, already launched on June 15, 2007, and the TanDEM-X satellite to be launched in May 2010. Both satellites carry the Tracking, Occultation and Ranging (TOR) payload supplied by the GFZ German Research Centre for Geosciences. The TOR consists of a high-precision dual-frequency GPS receiver, called Integrated GPS Occultation Receiver (IGOR), and a Laser retro-reflector (LRR) for precise orbit determination (POD) and atmospheric sounding. The IGOR is of vital importance for the TanDEM-X mission objectives as the millimeter level determination of the baseline or distance between the two spacecrafts is needed to derive meter level accurate DEMs. Within the TanDEM-X ground segment GFZ is responsible for the operational provision of precise baselines. For this GFZ uses two software chains, first its Earth Parameter and Orbit System (EPOS) software and second the BERNESE software, for backup purposes and quality control. In a concerted effort also the German Aerospace Center (DLR) generates precise baselines independently with a dedicated Kalman filter approach realized in its FRNS software. By the example of GRACE the generation of baselines with millimeter accuracy from on-board GPS data can be validated directly by way of comparing them to the intersatellite K-band range measurements. The K-band ranges are accurate down to the micrometer-level and therefore may be considered as truth. Both TanDEM-X baseline providers are able to generate GRACE baselines with sub-millimeter accuracy. By merging the independent baselines by GFZ and DLR, the accuracy can even be increased. The K-band validation however covers solely the along-track component as the K-band data measure just the distance between the two GRACE satellites. In addition they inhibit an un-known bias which must be modelled in the comparison, so the

Hydraulic correction method (HCM) to enhance the efficiency of SRTM DEM in flood modeling

Science.gov (United States)

Chen, Huili; Liang, Qiuhua; Liu, Yong; Xie, Shuguang

2018-04-01

Digital Elevation Model (DEM) is one of the most important controlling factors determining the simulation accuracy of hydraulic models. However, the currently available global topographic data is confronted with limitations for application in 2-D hydraulic modeling, mainly due to the existence of vegetation bias, random errors and insufficient spatial resolution. A hydraulic correction method (HCM) for the SRTM DEM is proposed in this study to improve modeling accuracy. Firstly, we employ the global vegetation corrected DEM (i.e. Bare-Earth DEM), developed from the SRTM DEM to include both vegetation height and SRTM vegetation signal. Then, a newly released DEM, removing both vegetation bias and random errors (i.e. Multi-Error Removed DEM), is employed to overcome the limitation of height errors. Last, an approach to correct the Multi-Error Removed DEM is presented to account for the insufficiency of spatial resolution, ensuring flow connectivity of the river networks. The approach involves: (a) extracting river networks from the Multi-Error Removed DEM using an automated algorithm in ArcGIS; (b) correcting the location and layout of extracted streams with the aid of Google Earth platform and Remote Sensing imagery; and (c) removing the positive biases of the raised segment in the river networks based on bed slope to generate the hydraulically corrected DEM. The proposed HCM utilizes easily available data and tools to improve the flow connectivity of river networks without manual adjustment. To demonstrate the advantages of HCM, an extreme flood event in Huifa River Basin (China) is simulated on the original DEM, Bare-Earth DEM, Multi-Error removed DEM, and hydraulically corrected DEM using an integrated hydrologic-hydraulic model. A comparative analysis is subsequently performed to assess the simulation accuracy and performance of four different DEMs and favorable results have been obtained on the corrected DEM.

Which DEM is best for analyzing fluvial landscape development in mountainous terrains?

Science.gov (United States)

Boulton, Sarah J.; Stokes, Martin

2018-06-01

Regional studies of fluvial landforms and long-term (Quaternary) landscape development in remote mountain landscapes routinely use satellite-derived DEM data sets. The SRTM and ASTER DEMs are the most commonly utilised because of their longer availability, free cost, and ease of access. However, rapid technological developments mean that newer and higher resolution DEM data sets such as ALOS World 3D (AW3D) and TanDEM-X are being released to the scientific community. Geomorphologists are thus faced with an increasingly problematic challenge of selecting an appropriate DEM for their landscape analyses. Here, we test the application of four medium resolution DEM products (30 m = SRTM, ASTER, AW3D; 12 m = TanDEM-X) for qualitative and quantitative analysis of a fluvial mountain landscape using the Dades River catchment (High Atlas Mountains, Morocco). This landscape comprises significant DEM remote sensing challenges, notably a high mountain relief, steep slopes, and a deeply incised high sinuosity drainage network with narrow canyon/gorge reaches. Our goal was to see which DEM produced the most representative best fit drainage network and meaningful quantification. To achieve this, we used ArcGIS and Stream Profiler platforms to generate catchment hillshade and slope rasters and to extract drainage network, channel long profile and channel slope, and area data. TanDEM-X produces the clearest landscape representation but with channel routing errors in localised high relief areas. Thirty-metre DEMs are smoother and less detailed, but the AW3D shows the closest fit to the real drainage network configuration. The TanDEM-X elevation values are the closest to field-derived GPS measurements. Long profiles exhibit similar shapes but with minor differences in length, elevation, and the degree of noise/smoothing, with AW3D producing the best representation. Slope-area plots display similarly positioned slope-break knickpoints with modest differences in steepness and concavity

Dynastic Marriage of Mamluk Sultan of Egypt al-Nasir and Princess Tulunbay according to Medieval Arab Chronicles

Full Text Available Objective: to identify the main reasons for the dynastic marriage between Mamluk Sultan al-Nasir and the Chinggisid princess Tulunbay and to analyze the impact of the termination of the marriage, according to medieval Arab chronicles. Research materials: medieval Arab chronicles of Mamluk authors: Ibn Duqmaq, al-Qalqashandi, al-Maqrizi, Mogultay, al-Nuwayri, Ibn Tagriberdi, al-Ayni et al. Results and novelty of the research: diplomatic relations between Egypt and the Golden Horde were the result of economic and foreign policy objectives of both states. Egypt at that time was one of the most powerful and influential states in the Muslim East, which showed an increased interest in events in the Golden Horde. This interest was stimulated by the fact that the Golden Horde was involved in the orbit of Islam and began to more intensively integrate Islam into the everyday culture of the Golden Horde society. After the Golden Horde had strengthened its position during the reign of khan Uzbek, Mamluk sultans began to consolidate even more their relations with the Golden Horde. One of the most important steps for the rapprochement between the two countries was a dynastic marriage between Mamluk Sultan al-Nasir and the Chinggisid princess Tulunbay. The object of this study is relevant, since the issue of political significance of dynastic relations between Mamluk and the Golden Horde rulers remain understudied. Meanwhile, the dynastic marriage is presented as a political act: as an expression of the good will of the state in relation to the other and a way to strengthen the influence of one country on another. The novelty of this research lies in the fact that, along with a detailed analysis of the Arab chronicles’ information on this subject, it presents for the first time the tomb of princess Tulunbay, which has been preserved in Egypt.

Cross Validation on the Equality of Uav-Based and Contour-Based Dems

Science.gov (United States)

Ma, R.; Xu, Z.; Wu, L.; Liu, S.

2018-04-01

Unmanned Aerial Vehicles (UAV) have been widely used for Digital Elevation Model (DEM) generation in geographic applications. This paper proposes a novel framework of generating DEM from UAV images. It starts with the generation of the point clouds by image matching, where the flight control data are used as reference for searching for the corresponding images, leading to a significant time saving. Besides, a set of ground control points (GCP) obtained from field surveying are used to transform the point clouds to the user's coordinate system. Following that, we use a multi-feature based supervised classification method for discriminating non-ground points from ground ones. In the end, we generate DEM by constructing triangular irregular networks and rasterization. The experiments are conducted in the east of Jilin province in China, which has been suffered from soil erosion for several years. The quality of UAV based DEM (UAV-DEM) is compared with that generated from contour interpolation (Contour-DEM).

Membaca Simbol pada Lukisan Pertempuran Antara Sultan Agung dan Jan Pieterszoon Coen (1974 Karya S. Sudjojono

Directory of Open Access Journals (Sweden)

Anak Agung Ayu Wulandari

2015-04-01

Full Text Available Sudjojono has produced hundreds of artworks, one of them is the painting of “The Battle between Sultan Agung and Jan Pieterszoon Coen”. Sizing 3 x 10 m, not only this painting is significant in size, it also shows Sudjojono’s in-depth study from aesthetic and historical side. The painting consists of 3 panels depicting Sultan Agung’s meeting with his royals, the battle scene between Mataram and Dutch troops, and the last panel depicting the meeting between JP Coen and Kyai Rangga. Some of the message conveyed by the painter is that the painting was 70% made of historical facts and did not come from the painter imagination only, better to be in peace than war and revenge and the last message is that western and eastern people are actually equal, and as eastern people should not need to have low self-esteem. Besides those messages there are still many symbols and signs that have in-depth meaning which will be studied and examined thoroughly such as figures involved in the battle, location of battle, clothing, etc.

Full Text Available Digital Elevation Model (DEM is one of the important parameters for soil erosion assessment. Notable uncertainties are observed in this study while using three high resolution open source DEMs. The Revised Universal Soil Loss Equation (RUSLE model has been applied to analysis the assessment of soil erosion uncertainty using open source DEMs (SRTM, ASTER and CARTOSAT and their increasing grid space (pixel size from the actual. The study area is a part of the Narmada river basin in Madhya Pradesh state, which is located in the central part of India and the area covered 20,558 km2. The actual resolution of DEMs is 30 m and their increasing grid spaces are taken as 90, 150, 210, 270 and 330 m for this study. Vertical accuracy of DEMs has been assessed using actual heights of the sample points that have been taken considering planimetric survey based map (toposheet. Elevations of DEMs are converted to the same vertical datum from WGS 84 to MSL (Mean Sea Level, before the accuracy assessment and modelling. Results indicate that the accuracy of the SRTM DEM with the RMSE of 13.31, 14.51, and 18.19 m in 30, 150 and 330 m resolution respectively, is better than the ASTER and the CARTOSAT DEMs. When the grid space of the DEMs increases, the accuracy of the elevation and calculated soil erosion decreases. This study presents a potential uncertainty introduced by open source high resolution DEMs in the accuracy of the soil erosion assessment models. The research provides an analysis of errors in selecting DEMs using the original and increased grid space for soil erosion modelling.

Glacier Volume Change Estimation Using Time Series of Improved Aster Dems

Science.gov (United States)

Girod, Luc; Nuth, Christopher; Kääb, Andreas

2016-06-01

Volume change data is critical to the understanding of glacier response to climate change. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) system embarked on the Terra (EOS AM-1) satellite has been a unique source of systematic stereoscopic images covering the whole globe at 15m resolution and at a consistent quality for over 15 years. While satellite stereo sensors with significantly improved radiometric and spatial resolution are available to date, the potential of ASTER data lies in its long consistent time series that is unrivaled, though not fully exploited for change analysis due to lack of data accuracy and precision. Here, we developed an improved method for ASTER DEM generation and implemented it in the open source photogrammetric library and software suite MicMac. The method relies on the computation of a rational polynomial coefficients (RPC) model and the detection and correction of cross-track sensor jitter in order to compute DEMs. ASTER data are strongly affected by attitude jitter, mainly of approximately 4 km and 30 km wavelength, and improving the generation of ASTER DEMs requires removal of this effect. Our sensor modeling does not require ground control points and allows thus potentially for the automatic processing of large data volumes. As a proof of concept, we chose a set of glaciers with reference DEMs available to assess the quality of our measurements. We use time series of ASTER scenes from which we extracted DEMs with a ground sampling distance of 15m. Our method directly measures and accounts for the cross-track component of jitter so that the resulting DEMs are not contaminated by this process. Since the along-track component of jitter has the same direction as the stereo parallaxes, the two cannot be separated and the elevations extracted are thus contaminated by along-track jitter. Initial tests reveal no clear relation between the cross-track and along-track components so that the latter seems not to be

Novel application of DEM to modelling comminution processes

International Nuclear Information System (INIS)

Delaney, Gary W; Cleary, Paul W; Sinnott, Matt D; Morrison, Rob D

2010-01-01

Comminution processes in which grains are broken down into smaller and smaller sizes represent a critical component in many industries including mineral processing, cement production, food processing and pharmaceuticals. We present a novel DEM implementation capable of realistically modelling such comminution processes. This extends on a previous implementation of DEM particle breakage that utilized spherical particles. Our new extension uses super-quadric particles, where daughter fragments with realistic size and shape distributions are packed inside a bounding parent super-quadric. We demonstrate the flexibility of our approach in different particle breakage scenarios and examine the effect of the chosen minimum resolved particle size. This incorporation of the effect of particle shape in the breakage process allows for more realistic DEM simulations to be performed, that can provide additional fundamental insights into comminution processes and into the behaviour of individual pieces of industrial machinery.

2017-10-01

The primary objective of the TanDEM-X mission is the generation of a global, consistent, and high-resolution digital elevation model (DEM) with unprecedented global accuracy. The goal is achieved by exploiting the interferometric capabilities of the two twin SAR satellites TerraSAR-X and TanDEM-X, which fly in a close orbit formation, acting as an X-band single-pass interferometer. Between December 2010 and early 2015 all land surfaces have been acquired at least twice, difficult terrain up to seven or eight times. The acquisition strategy, data processing, and DEM calibration and mosaicking have been systematically monitored and optimized throughout the entire mission duration, in order to fulfill the specification. The processing of all data has finally been completed in September 2016 and this paper reports on the final performance of the TanDEM-X global DEM and presents the acquisition and processing strategy which allowed to obtain the final DEM quality. The results confirm the outstanding global accuracy of the delivered product, which can be now utilized for both scientific and commercial applications.

High spatial resolution X-band interferometric SAR data from the TanDEM-X, in the operational DEM generation mode, are sensitive to forest structure and can therefore be used for thematic boreal forest classification of forest environments. The interferometric coherence in absence of temporal decorrelation depends strongly on forest height and structure. Due to the rather homogenous structure of boreal forest, forest biomass can be derived from forest height, on the basis of allometric equati...

Modelling above Ground Biomass in Tanzanian Miombo Woodlands Using TanDEM-X WorldDEM and Field Data

Directory of Open Access Journals (Sweden)

Stefano Puliti

2017-09-01

Full Text Available The use of Interferometric Synthetic Aperture Radar (InSAR data has great potential for monitoring large scale forest above ground biomass (AGB in the tropics due to the increased ability to retrieve 3D information even under cloud cover. To date; results in tropical forests have been inconsistent and further knowledge on the accuracy of models linking AGB and InSAR height data is crucial for the development of large scale forest monitoring programs. This study provides an example of the use of TanDEM-X WorldDEM data to model AGB in Tanzanian woodlands. The primary objective was to assess the accuracy of a model linking AGB with InSAR height from WorldDEM after the subtraction of ground heights. The secondary objective was to assess the possibility of obtaining InSAR height for field plots when the terrain heights were derived from global navigation satellite systems (GNSS; i.e., as an alternative to using airborne laser scanning (ALS. The results revealed that the AGB model using InSAR height had a predictive accuracy of R M S E = 24.1 t·ha−1; or 38.8% of the mean AGB when terrain heights were derived from ALS. The results were similar when using terrain heights from GNSS. The accuracy of the predicted AGB was improved when compared to a previous study using TanDEM-X for a sub-area of the area of interest and was of similar magnitude to what was achieved in the same sub-area using ALS data. Overall; this study sheds new light on the opportunities that arise from the use of InSAR data for large scale AGB modelling in tropical woodlands.

Surface topography is among the most fundamental data sets for geosciences, essential for disciplines ranging from glaciology to geodynamics. The ArcticDEM project is using sub-meter, commercial imagery licensed by the National Geospatial-Intelligence Agency, petascale computing, and open source photogrammetry software to produce a time-tagged 2m posting elevation model and a 5m posting mosaic of the entire Arctic region. As ArcticDEM enters its third year, the region has gone from having some of the sparsest and poorest elevation data to some of the most precise and complete data of any region on the globe. To date, we have produced and released over 80,000,000 km2 as 57,000 - 2m posting, time-stamped DEMs. The Arctic, on average, is covered four times though there are hotspots with more than 100 DEMs. In addition, the version 1 release includes a 5m posting mosaic covering the entire 20,000,000 km2 region. All products are publically available through arctidem.org, ESRI web services, and a web viewer. The final year of the project will consist of a complete refiltering of clouds/water and re-mosaicing of all elevation data. Since inception of the project, post-processing techniques have improved significantly, resulting in fewer voids, better registration, sharper coastlines, and fewer inaccuracies due to clouds. All ArcticDEM data will be released in 2018. Data, documentation, web services and web viewer are available at arcticdem.org

Full Text Available Advanced Spaceborne Thermal Emission and Reflection Radiometer-Global Digital Elevation Model (ASTER GDEM, Shuttle Radar Topography Mission (SRTM, and Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010 are freely available Digital Elevation Model (DEM datasets for environmental modeling and studies. The quality of spatial resolution and vertical accuracy of the DEM data source has a great influence particularly on the accuracy specifically for inundation mapping. Most of the coastal inundation risk studies used the publicly available DEM to estimated the coastal inundation and associated damaged especially to human population based on the increment of sea level. In this study, the comparison between ground truth data from Global Positioning System (GPS observation and DEM is done to evaluate the accuracy of each DEM. The vertical accuracy of SRTM shows better result against ASTER and GMTED10 with an RMSE of 6.054 m. On top of the accuracy, the correlation of DEM is identified with the high determination of coefficient of 0.912 for SRTM. For coastal zone area, DEMs based on airborne light detection and ranging (LiDAR dataset was used as ground truth data relating to terrain height. In this case, the LiDAR DEM is compared against the new SRTM DEM after applying the scale factor. From the findings, the accuracy of the new DEM model from SRTM can be improved by applying scale factor. The result clearly shows that the value of RMSE exhibit slightly different when it reached 0.503 m. Hence, this new model is the most suitable and meets the accuracy requirement for coastal inundation risk assessment using open source data. The suitability of these datasets for further analysis on coastal management studies is vital to assess the potentially vulnerable areas caused by coastal inundation.

The Personality of Sultan Baybars and His Role in Developing Relations of the Mamluk Egypt with the Golden Horde according to Arab Sources

Full Text Available Objective: To consider the personality of the Mamluk Sultan Baybars and his role in developing relations with the Golden Horde. Research materials: The medieval Arabic chronicles of Sultan Baybars’ first biographers, Abd al-Zahir and Ibn Shaddad, as well as the information of later authors – Rukn al-Din Baybars, al-Maqrizi, al-Nuwayri, al-Ayni, and others. Results and novelty of the research: It is known that close relations with Berke Khan of the Golden Horde were developed during the reign of Sultan Baybars. The purpose of this alliance was the desire to neutralize the role of the Hulaguid state in the international arena. The fact that Baybars was of Kipchak origin was an important contributor to friendly relations. Despite the different information of medieval Arab authors regarding which original clan Baybars belonged to, we can quite definitely say that Baybars originated from the Barli tribe, based on the information of his main biographer Abd al-Zahir. The person of Baybars left its mark not only in the history of Mamluk Egypt, but also in the global historical context of the Muslim world. Both the promotion of their political interests and the preservation of cultural identity played an important role in the interrelations of Baybars with Berke Khan of the Golden Horde.

Application of calorimetry to the assessment of the performance of ITER Nb3Sn TF conductor samples in SULTAN tests

Richard, L Savoldi; Zanino, R

2008-01-01

In the frame of the International Thermonuclear Experimental Reactor (ITER), several short full-size Nb 3 Sn samples of candidate toroidal field (TF) conductors were tested in 2007 at the SULTAN facility, PSI Villigen, Switzerland, in conditions relevant to the ITER TF (background magnetic field of 10.78 T and transport current of 68 kA). The performance of a SULTAN sample is determined by the current sharing temperature T CS . This can be obtained in principle from voltage measurements along the conductor sample, but the procedure is not free of issues and ambiguities. Here a complementary approach, based on the calorimetric assessment of the Joule heating due to current sharing, is critically discussed. Suitable algorithms are defined and the respective error bars are estimated, also based on numerical thermal-hydraulic modeling. The calorimetric approach is then applied to assess the performance of the samples tested in 2007 and compared with the results of the standard (electrical) approach

We developed MMASTER, an improved method for ASTER DEM generation and implemented it in the open source photogrammetric library and software suite MicMac. The method relies on the computation of a rational polynomial coefficients (RPC) model and the detection and correction of cross-track sensor jitter in order to compute DEMs. Our sensor modeling does not require ground control points and thus potentially allows for automatic processing of large data volumes. When compared to ground truth data, we have assessed a ±5m accuracy in DEM differencing when using our processing method, improved from the ±30m when using the AST14DMO DEM product. We demonstrate and discuss this improved ASTER DEM quality for a number of glaciers in Greenland (See figure attached), Alaska, and Svalbard. The quality of our measurements promises to further unlock the underused potential of ASTER DEMs for glacier volume change time series on a global scale. The data produced by our method will thus help to better understand the response of glaciers to climate change and their influence on runoff and sea level.

Was uns nicht umbringt, macht uns härter? Resilienzförderung bei armen Kindern aus Sicht des Capability-Ansatzes

Directory of Open Access Journals (Sweden)

Gutwald Rebecca

2015-07-01

Full Text Available Resilienz wird in der Psychologie und Sozialpädagogik häufig als positiv angesehen. In der Armutsbekämpfung ist diese Sichtweise durchaus nachvollziehbar, insbesondere in der Prävention von Kinderarmut: wenn Resilienz das ist, was ein Kind in die Lage versetzt, die Risiken und negativen Folgen von Armut besser zu bewältigen, scheint es sinnvoll, diese Fähigkeit bei Kindern zu fördern. Mein Beitrag befürwortet diesen Befund, plädiert aber dafür, dass die Resilienzdebatte der Untermauerung durch Argumente aus der praktischen Philosophie bedarf, da das, was häufig als Resilienz bezeichnet wird, nicht immer positiv zu bewerten ist. Ziel meines Beitrags ist es, den Resilienzdiskurs im Rahmen der Kinderarmutsbekämpfung in einer normativen Theorie zu verankern: im Capability Ansatz von Amartya Sen. Resilienz wird damit, so meine These, zu einem fundamental normativen Begriff. Mein Beitrag gliedert sich in drei Teile: Zuerst wird auf die Grundideen des CA und die Stellung von Kindheit darin eingegangen. Im zweiten Teil wird der Resilienzbegriff im Kontext von Kinderarmutsprävention charakterisiert. Der dritte Teil widmet sich den Verbindungslinien zwischen der Resilienzdiskussion und dem CA. Leitgedanke ist dabei, dass der CA die menschliche Handlungsfähigkeit als normativ grundlegend auszeichnet. Auf dieser Basis lässt sich überzeugend beurteilen, warum Armut bei Kindern höchst problematisch ist und welches Ziel in der Resilienzförderung verfolgt werden soll. Wie ich argumentieren werde, ist die Bereitstellung von capabilities auch die gerechtigkeitstheoretische Basis von Resilienzförderung in der Praxis. Der Beitrag schließt mit Impulsen, welche, so meine Hoffnung, für eine weitere Diskussion der Normativität von Resilienz dienlich sein können.

Sewage sludge disposal and recycling; Klaerschlammverwertung mit dem Ziel der Schadstoff-Wertstofftrennung

Hahn, J. [Umweltbundesamt, Abt. III 3 - Abfall- und Awasserwirtschaft, Berlin (Germany)

2002-07-01

The potential land pollution from sewage sludge used as agricultural fertilizer was investigated. It was found that sewage sludge contains high levels of heavy metals which will accumulate in the soil to an unacceptable level. Further, it is to be expected that sewage sludge will contain problematic organic pollutants discharged from private households and industrial processes which are not completely removed or filtered out in the sewage plant. Recovery of phosphates is necessary because the supply of phosphate worldwide is limited, and there is no substitute for phosphates as fertilizers. The measures outlined in this contribution should become part of national and EU regulations. [German] Es wurde untersucht, welche Schadstoffeintraege in den Boden durch die Verwendung von Klaerschlaemmen entsprechend den Vorgaben der geltenden deutschen Klaerschlammverordnung in der Praxis zu erwarten und welche Austraege gleichzeitig durch Auswaschung und Erntevorgang in Rechnung zu stellen sind: Danach fuehrt die Klaerschlammduengung zu erhoehten Eintraegen von Schwermetallen und somit ueber die Jahre zu einer Anreicherung im Boden, die auf Dauer nicht akzeptabel ist. Ausserdem ist davon auszugehen, dass Klaerschlaemme aufgrund von Abwassereinleitungen aus privaten Haushalten und Gewerbe eine Vielzahl von problematischen organischen Schadstoffen enthalten, die in den Klaeranlagen nicht abgebaut oder abgetrennt werden und die sich deshalb im Klaerschlamm wiederfinden. Die Rueckgewinnung von Phosphat aus Klaerschlamm und Abwasser ist notwendig, weil die Phosphatvorkommen weltweit begrenzt und Phosphate als Duengemittel nicht ersetzbar sind. Die dargestellten Massnahmen sollen sowohl in die nationalen als auch die EU-Regelungen eingebracht werden. (orig.)

Volcanic geomorphology using TanDEM-X

Science.gov (United States)

Poland, Michael; Kubanek, Julia

2016-04-01

Topography is perhaps the most fundamental dataset for any volcano, yet is surprisingly difficult to collect, especially during the course of an eruption. For example, photogrammetry and lidar are time-intensive and often expensive, and they cannot be employed when the surface is obscured by clouds. Ground-based surveys can operate in poor weather but have poor spatial resolution and may expose personnel to hazardous conditions. Repeat passes of synthetic aperture radar (SAR) data provide excellent spatial resolution, but topography in areas of surface change (from vegetation swaying in the wind to physical changes in the landscape) between radar passes cannot be imaged. The German Space Agency's TanDEM-X satellite system, however, solves this issue by simultaneously acquiring SAR data of the surface using a pair of orbiting satellites, thereby removing temporal change as a complicating factor in SAR-based topographic mapping. TanDEM-X measurements have demonstrated exceptional value in mapping the topography of volcanic environments in as-yet limited applications. The data provide excellent resolution (down to ~3-m pixel size) and are useful for updating topographic data at volcanoes where surface change has occurred since the most recent topographic dataset was collected. Such data can be used for applications ranging from correcting radar interferograms for topography, to modeling flow pathways in support of hazards mitigation. The most valuable contributions, however, relate to calculating volume changes related to eruptive activity. For example, limited datasets have provided critical measurements of lava dome growth and collapse at volcanoes including Merapi (Indonesia), Colima (Mexico), and Soufriere Hills (Montserrat), and of basaltic lava flow emplacement at Tolbachik (Kamchatka), Etna (Italy), and Kīlauea (Hawai`i). With topographic data spanning an eruption, it is possible to calculate eruption rates - information that might not otherwise be available

Influence of Terraced area DEM Resolution on RUSLE LS Factor

Zhang, Hongming; Baartman, Jantiene E. M.; Yang, Xiaomei; Gai, Lingtong; Geissen, Viollette

2017-04-01

Topography has a large impact on the erosion of soil by water. Slope steepness and slope length are combined (the LS factor) in the universal soil-loss equation (USLE) and its revised version (RUSLE) for predicting soil erosion. The LS factor is usually extracted from a digital elevation model (DEM). The grid size of the DEM will thus influence the LS factor and the subsequent calculation of soil loss. Terracing is considered as a support practice factor (P) in the USLE/RUSLE equations, which is multiplied with the other USLE/RUSLE factors. However, as terraces change the slope length and steepness, they also affect the LS factor. The effect of DEM grid size on the LS factor has not been investigated for a terraced area. We obtained a high-resolution DEM by unmanned aerial vehicles (UAVs) photogrammetry, from which the slope steepness, slope length, and LS factor were extracted. The changes in these parameters at various DEM resolutions were then analysed. The DEM produced detailed LS-factor maps, particularly for low LS factors. High (small valleys, gullies, and terrace ridges) and low (flats and terrace fields) spatial frequencies were both sensitive to changes in resolution, so the areas of higher and lower slope steepness both decreased with increasing grid size. Average slope steepness decreased and average slope length increased with grid size. Slope length, however, had a larger effect than slope steepness on the LS factor as the grid size varied. The LS factor increased when the grid size increased from 0.5 to 30-m and increased significantly at grid sizes >5-m. The LS factor was increasingly overestimated as grid size decreased. The LS factor decreased from grid sizes of 30 to 100-m, because the details of the terraced terrain were gradually lost, but the factor was still overestimated.

The objective of this study was to enhance understanding of the sensitivity of the SWAT model to the resolutions of Digital Elevation Models (DEMs) based on the analysis of multiple evaluation indicators. The Xiangxi River, a large tributary of Three Gorges Reservoir in China, was selected as the study area. A range of 17 DEM spatial resolutions, from 30 to 1000 m, was examined, and the annual and monthly model outputs based on each resolution were compared. The following results were obtained: (i) sediment yield was greatly affected by DEM resolution; (ii) the prediction of dissolved oxygen load was significantly affected by DEM resolutions coarser than 500 m; (iii) Total Nitrogen (TN) load was not greatly affected by the DEM resolution; (iv) Nitrate Nitrogen (NO₃-N) and Total Phosphorus (TP) loads were slightly affected by the DEM resolution; and (v) flow and Ammonia Nitrogen (NH₄-N) load were essentially unaffected by the DEM resolution. The flow and dissolved oxygen load decreased more significantly in the dry season than in the wet and normal seasons. Excluding flow and dissolved oxygen, the uncertainties of the other Hydrology/Non-point Source (H/NPS) pollution indicators were greater in the wet season than in the dry and normal seasons. Considering the temporal distribution uncertainties, the optimal DEM resolutions for flow was 30-200 m, for sediment and TP was 30-100 m, for dissolved oxygen and NO₃-N was 30-300 m, for NH₄-N was 30 to 70 m and for TN was 30-150 m.

Spatial Characterization of Landscapes through Multifractal Analysis of DEM

Directory of Open Access Journals (Sweden)

P. L. Aguado

2014-01-01

Full Text Available Landscape evolution is driven by abiotic, biotic, and anthropic factors. The interactions among these factors and their influence at different scales create a complex dynamic. Landscapes have been shown to exhibit numerous scaling laws, from Horton’s laws to more sophisticated scaling of heights in topography and river network topology. This scaling and multiscaling analysis has the potential to characterise the landscape in terms of the statistical signature of the measure selected. The study zone is a matrix obtained from a digital elevation model (DEM (map 10 × 10 m, and height 1 m that corresponds to homogeneous region with respect to soil characteristics and climatology known as “Monte El Pardo” although the water level of a reservoir and the topography play a main role on its organization and evolution. We have investigated whether the multifractal analysis of a DEM shows common features that can be used to reveal the underlying patterns and information associated with the landscape of the DEM mapping and studied the influence of the water level of the reservoir on the applied analysis. The results show that the use of the multifractal approach with mean absolute gradient data is a useful tool for analysing the topography represented by the DEM.

Artificial terraced field extraction based on high resolution DEMs

2017-04-01

With the increase of human activities, artificial landforms become one of the main terrain features with special geographical and hydrological value. Terraced field, as the most important artificial landscapes of the loess plateau, plays an important role in conserving soil and water. With the development of digital terrain analysis (DTA), there is a current and future need in developing a robust, repeatable and cost-effective research methodology for terraced fields. In this paper, a novel method using bidirectional DEM shaded relief is proposed for terraced field identification based on high resolution DEM, taking Zhifanggou watershed, Shannxi province as the study area. Firstly, 1m DEM is obtained by low altitude aerial photogrammetry using Unmanned Aerial Vehicle (UAV), and 0.1m DOM is also obtained as the test data. Then, the positive and negative terrain segmentation is done to acquire the area of terraced field. Finally, a bidirectional DEM shaded relief is simulated to extract the ridges of each terraced field stages. The method in this paper can get not only polygon feature of the terraced field areas but also line feature of terraced field ridges. The accuracy is 89.7% compared with the artificial interpretation result from DOM. And additional experiment shows that this method has a strong robustness as well as high accuracy.

DEM-based research on the landform features of China

Landforms can be described and identified by parameterization of digital elevation model (DEM). This paper discusses the large-scale geomorphological characteristics of China based on numerical analysis of terrain parameters and develop a methodology for characterizing landforms from DEMs. The methodology is implemented as a two-step process. First, terrain variables are derived from a 1-km DEM in a given statistical unit including local relief, the earth's surface incision, elevation variance coefficient, roughness, mean slope and mean elevation. Second, every parameter regarded as a single-band image is combined into a multi-band image. Then ISODATA unsupervised classification and the Bayesian technique of Maximum Likelihood supervised classification are applied for landform classification. The resulting landforms are evaluated by the means of Stratified Sampling with respect to an existing map and the overall classification accuracy reaches to rather high value. It's shown that the derived parameters carry sufficient physiographic information and can be used for landform classification. Since the classification method integrates manifold terrain indexes, conquers the limitation of the subjective cognition, as well as a low cost, apparently it could represent an applied foreground in the classification of macroscopic relief forms. Furthermore, it exhibits significance in consummating the theory and the methodology of DEMs on digital terrain analysis.

The primary goal of the German TanDEM-X mission is the generation of a highly accurate and global Digital Elevation Model (DEM) with global accuracies of at least 10 m absolute height error (linear 90% error). The global TanDEM-X DEM acquired with single-pass SAR interferometry was finished in September 2016. This paper provides a unique accuracy assessment of the final TanDEM-X global DEM using two different GPS point reference data sets, which are distributed across all continents, to fully characterize the absolute height error. Firstly, the absolute vertical accuracy is examined by about three million globally distributed kinematic GPS (KGPS) points derived from 19 KGPS tracks covering a total length of about 66,000 km. Secondly, a comparison is performed with more than 23,000 "GPS on Bench Marks" (GPS-on-BM) points provided by the US National Geodetic Survey (NGS) scattered across 14 different land cover types of the US National Land Cover Data base (NLCD). Both GPS comparisons prove an absolute vertical mean error of TanDEM-X DEM smaller than ±0.20 m, a Root Means Square Error (RMSE) smaller than 1.4 m and an excellent absolute 90% linear height error below 2 m. The RMSE values are sensitive to land cover types. For low vegetation the RMSE is ±1.1 m, whereas it is slightly higher for developed areas (±1.4 m) and for forests (±1.8 m). This validation confirms an outstanding absolute height error at 90% confidence level of the global TanDEM-X DEM outperforming the requirement by a factor of five. Due to its extensive and globally distributed reference data sets, this study is of considerable interests for scientific and commercial applications.

Plaßmann, Wilfried

Die hier betrachteten Signale werden auch als stochastische Signale bezeichnet. Sie sind zufällig, d. h. ihr Augenblickswert ist nicht vorhersagbar. Abb. 118.1 zeigt eine Unterteilung nach den Signaleigenschaften. Über die nichtstationären Signale lässt sich keinerlei Aussage machen, und sie werden hier deshalb auch nicht weiter betrachtet. Für die stationären Signale gilt, dass ihr Momentanwert zwar auch nicht vorhergesagt werden kann, dass sie aber trotzdem gewisse auswertbare Eigenschaften besitzen, die allerdings statistischer Art sind und deshalb nur mit den Gesetzen der Wahrscheinlichkeitstheorie erfasst werden können. Zwar sind - theoretisch - für die Anwendung der Wahrscheinlichkeitstheorie unendlich viele Probenwerte zu nehmen, in der Praxis hat sich aber gezeigt, dass man auch mit einer endlichen Anzahl dem gesuchten Wert schon ausreichend nahe kommen kann.

DEM Resolution Impact on the Estimation of the Physical Characteristics of Watersheds by Using SWAT

2016-01-01

Full Text Available A digital elevation model (DEM is an important spatial input for automatic extraction of topographic parameters for the soil and water assessment tool (SWAT. The objective of this study was to investigate the impact of DEM resolution (from 5 to 90 m on the delineation process of a SWAT model with two types of watershed characteristics (flat area and mountain area and three sizes of watershed area (about 20,000, 200,000, and 1,500,000 hectares. The results showed that the total lengths of the streamline, main channel slope, watershed area, and area slope were significantly different when using the DEM datasets to delineate. Delineation using the SRTM DEM (90 m, ASTER DEM (30 m, and LDD DEM (5 m for all watershed characteristics showed that the watershed sizes and shapes obtained were only slightly different, whereas the area slopes obtained were significantly different. The total lengths of the generated streams increased when the resolution of the DEM used was higher. The stream slopes obtained using the small area sizes were insignificant, whereas the slopes obtained using the large area sizes were significantly different. This suggests that water resource model users should use the ASTER DEM as opposed to a finer resolution DEM for model input to save time for the model calibration and validation.

Dem Generation from Close-Range Photogrammetry Using Extended Python Photogrammetry Toolbox

Science.gov (United States)

Belmonte, A. A.; Biong, M. M. P.; Macatulad, E. G.

2017-10-01

Digital elevation models (DEMs) are widely used raster data for different applications concerning terrain, such as for flood modelling, viewshed analysis, mining, land development, engineering design projects, to name a few. DEMs can be obtained through various methods, including topographic survey, LiDAR or photogrammetry, and internet sources. Terrestrial close-range photogrammetry is one of the alternative methods to produce DEMs through the processing of images using photogrammetry software. There are already powerful photogrammetry software that are commercially-available and can produce high-accuracy DEMs. However, this entails corresponding cost. Although, some of these software have free or demo trials, these trials have limits in their usable features and usage time. One alternative is the use of free and open-source software (FOSS), such as the Python Photogrammetry Toolbox (PPT), which provides an interface for performing photogrammetric processes implemented through python script. For relatively small areas such as in mining or construction excavation, a relatively inexpensive, fast and accurate method would be advantageous. In this study, PPT was used to generate 3D point cloud data from images of an open pit excavation. The PPT was extended to add an algorithm converting the generated point cloud data into a usable DEM.

The role of DEM at CERN

CERN Document Server

Van der Bij, E

2005-01-01

The DEM group in the Technical Support department provides services for the fabrication of special printed circuits that are invaluable for the whole particle physics community. The capability is based around a core technology that is developed by using skills to etch and process materials that are not commonly used in industry, combined with production methods used in PCB manufacturing. The role of the prototyping facilities is to assist engineers and physicists and to offer them easy access to competencies often not available from industry. At the same time, with the expertise and production capacity available, it makes that CERN is always geared up to handle emergency situations. The design office and the assembly workshop that are also part of DEM have similar roles that lower the cost and improve the quality and maintainability of electronics developed at CERN.

Developmental Eye Movement (DEM Test Norms for Mandarin Chinese-Speaking Chinese Children.

Yachun Xie

Full Text Available The Developmental Eye Movement (DEM test is commonly used as a clinical visual-verbal ocular motor assessment tool to screen and diagnose reading problems at the onset. No established norm exists for using the DEM test with Mandarin Chinese-speaking Chinese children. This study aims to establish the normative values of the DEM test for the Mandarin Chinese-speaking population in China; it also aims to compare the values with three other published norms for English-, Spanish-, and Cantonese-speaking Chinese children. A random stratified sampling method was used to recruit children from eight kindergartens and eight primary schools in the main urban and suburban areas of Nanjing. A total of 1,425 Mandarin Chinese-speaking children aged 5 to 12 years took the DEM test in Mandarin Chinese. A digital recorder was used to record the process. All of the subjects completed a symptomatology survey, and their DEM scores were determined by a trained tester. The scores were computed using the formula in the DEM manual, except that the "vertical scores" were adjusted by taking the vertical errors into consideration. The results were compared with the three other published norms. In our subjects, a general decrease with age was observed for the four eye movement indexes: vertical score, adjusted horizontal score, ratio, and total error. For both the vertical and adjusted horizontal scores, the Mandarin Chinese-speaking children completed the tests much more quickly than the norms for English- and Spanish-speaking children. However, the same group completed the test slightly more slowly than the norms for Cantonese-speaking children. The differences in the means were significant (P0.05; compared with Spanish-speaking children, the scores were statistically significant (P0.05. DEM norms may be affected by differences in language, cultural, and educational systems among various ethnicities. The norms of the DEM test are proposed for use with Mandarin Chinese

Lee, Seung-Kuk; Ryu, Joo-Hyung

2017-01-01

This study explored the feasibility of using TanDEM-X (TDX) interferometric observations of tidal flats for digital elevation model (DEM) construction. Our goal was to generate high-precision DEMs in tidal flat areas, because accurate intertidal zone data are essential for monitoring coastal environment sand erosion processes. To monitor dynamic coastal changes caused by waves, currents, and tides, very accurate DEMs with high spatial resolution are required. The bi- and monostatic modes of the TDX interferometer employed during the TDX science phase provided a great opportunity for highly accurate intertidal DEM construction using radar interferometry with no time lag (bistatic mode) or an approximately 10-s temporal baseline (monostatic mode) between the master and slave synthetic aperture radar image acquisitions. In this study, DEM construction in tidal flat areas was first optimized based on the TDX system parameters used in various TDX modes. We successfully generated intertidal zone DEMs with 57-m spatial resolutions and interferometric height accuracies better than 0.15 m for three representative tidal flats on the west coast of the Korean Peninsula. Finally, we validated these TDX DEMs against real-time kinematic-GPS measurements acquired in two tidal flat areas; the correlation coefficient was 0.97 with a root mean square error of 0.20 m.

2018-04-01

Flood is one type of natural disaster that occurs almost every year in Malaysia. Commonly the lowland areas are the worst affected areas. This kind of disaster is controllable by using an accurate data for proposing any kinds of solutions. Elevation data is one of the data used to produce solutions for flooding. Currently, the research about the application of Digital Elevation Model (DEM) in hydrology was increased where this kind of model will identify the elevation for required areas. University of Tun Hussein Onn Malaysia is one of the lowland areas which facing flood problems on 2006. Therefore, this area was chosen in order to produce DEM which focussed on University Health Centre (PKU) and drainage area around Civil and Environment Faculty (FKAAS). Unmanned Aerial Vehicle used to collect aerial photos data then undergoes a process of generating DEM according to three types of accuracy and quality from Agisoft PhotoScan software. The higher the level of accuracy and quality of DEM produced, the longer time taken to generate a DEM. The reading of the errors created while producing the DEM shows almost 0.01 different. Therefore, it has been identified there are some important parameters which influenced the accuracy of DEM.

Produced by radar data or stereo remote sensing image pairs, global DEM datasets are one of the most important types for DEM data. Relative error relates to surface quality created by DEM data, so it relates to geomorphology and hydrologic applications using DEM data. Taking Shanxi Plateau of China as the study area, this research evaluated the relative error to typical open global DEM datasets including Shuttle Radar Terrain Mission (SRTM) data with 1 arc second resolution (SRTM1), SRTM data with 3 arc second resolution (SRTM3), ASTER global DEM data in the second version (GDEM-v2) and ALOS world 3D-30m (AW3D) data. Through process and selection, more than 300,000 ICESat/GLA14 points were used as the GCP data, and the vertical error was computed and compared among four typical global DEM datasets. Then, more than 2,600,000 ICESat/GLA14 point pairs were acquired using the distance threshold between 100 m and 500 m. Meanwhile, the horizontal distance between every point pair was computed, so the relative error was achieved using slope values based on vertical error difference and the horizontal distance of the point pairs. Finally, false slope ratio (FSR) index was computed through analyzing the difference between DEM and ICESat/GLA14 values for every point pair. Both relative error and FSR index were categorically compared for the four DEM datasets under different slope classes. Research results show: Overall, AW3D has the lowest relative error values in mean error, mean absolute error, root mean square error and standard deviation error; then the SRTM1 data, its values are a little higher than AW3D data; the SRTM3 and GDEM-v2 data have the highest relative error values, and the values for the two datasets are similar. Considering different slope conditions, all the four DEM data have better performance in flat areas but worse performance in sloping regions; AW3D has the best performance in all the slope classes, a litter better than SRTM1; with slope increasing

Full Text Available Nach der starken Kritik der Medienberichterstattung über Terrorismus, besonders nach dem 11.09.2001, werden die theoretischen Hintergründe ausgewählter Kritikpunkte betrachtet und ein weiteres terroristisches Ereignis, die Anschläge in Kenia am 28.11.2002, inhaltsanalytisch untersucht. Ziel dabei ist es, Aussagen bezüglich inhaltlicher und formaler Merkmale der Fernseh-berichterstattung über ein terroristisches Ereignis zu treffen. Deshalb liegt der Fokus auf den folgenden drei Forschungsfragen: 1. Welche Nachrichtenfaktoren spielen für die Selektion und Intensität der Berichterstattung über das terroristische Ereignis eine Rolle? 2. Wird mit Emotionalisierung gearbeitet? 3. Liegen negative Stereotype und/oder Feindbilder bezüglich der islamischen und arabischen Welt vor? Die Ergebnisse der Untersuchung zeigen erwartete Tendenzen sowohl die Merkmale der Terrorismusberichterstattung als auch die Senderkonvergenzen und -divergenzen im dualen System betreffend. Der Nachrichtenwert eines terroristischen Ereignisses ist anfänglich sehr hoch, jedoch verliert das Ereignis ab dem dritten Tag aufgrund diverser Nachrichtenfaktoren deutlich an Beachtung in der Berichterstattung. Das Vorkommen emotionalisierender Mittel wird empirisch bestätigt. Nicht nur emotionale Sprache und Sprechweise, sondern vor allem Formen der expliziten Emotionalisierung sind vertreten. Damit wird die Vermutung bekräftigt, dass die Medien die mit den terroristischen Ereignissen verbundene beängstigende Stimmung senderabhängig unterschiedlich stark aufgreifen. Ein direkter islamischer Feindbildaufbau ist in der Berichterstattung nicht zu verzeichnen. Allerdings liegen latente negative Bewertungstendenzen sowie negative Stereotype bezüglich der arabischen und islamischen Welt vor, die das seit dem 11.09.2001 negativ geprägte Bild festigen. Die meist narrativ inszenierte Fixierung auf Bin Laden und al Qaida erfolgt oberflächlich und vernachlässigt m

In the 13th Five-Year Plan for Geoinformatics Business, it is proposed that the new InSAR technology should be applied to surveying and mapping production, which will become the innovation driving force of geoinformatics industry. This paper will study closely around the new outline of surveying and mapping and then achieve the TerraSAR/TanDEM data of Bin County in Shaanxi Province in X band. The studying steps are as follows; Firstly, the baseline is estimated from the orbital data; Secondly, the interferometric pairs of SAR image are accurately registered; Thirdly, the interferogram is generated; Fourth, the interferometric correlation information is estimated and the flat-earth phase is removed. In order to solve the phase noise and the discontinuity phase existing in the interferometric image of phase, a GAMMA adaptive filtering method is adopted. Aiming at the "hole" problem of missing data in low coherent area, the interpolation method of low coherent area mask is used to assist the phase unwrapping. Then, the accuracy of the interferometric baseline is estimated from the ground control points. Finally, 1 : 50000 DEM is generated, and the existing DEM data is used to verify the accuracy through statistical analysis. The research results show that the improved InSAR data processing method in this paper can obtain the high-precision DEM of the study area, exactly the same with the topography of reference DEM. The R2 can reach to 0.9648, showing a strong positive correlation.

Full Text Available Images from two sensors, the High-Resolution Imaging Science Experiment (HiRISE and the Context Camera (CTX, both on-board the Mars Reconnaissance Orbiter (MRO, were used to generate high-quality DEMs (Digital Elevation Models of the Martian surface. However, there were discrepancies between the DEMs generated from the images acquired by these two sensors due to various reasons, such as variations in boresight alignment between the two sensors during the flight in the complex environment. This paper presents a systematic investigation of the discrepancies between the DEMs generated from the HiRISE and CTX images. A combined adjustment algorithm is presented for the co-registration of HiRISE and CTX DEMs. Experimental analysis was carried out using the HiRISE and CTX images collected at the Mars Rover landing site and several other typical regions. The results indicated that there were systematic offsets between the HiRISE and CTX DEMs in the longitude and latitude directions. However, the offset in the altitude was less obvious. After combined adjustment, the offsets were eliminated and the HiRISE and CTX DEMs were co-registered to each other. The presented research is of significance for the synergistic use of HiRISE and CTX images for precision Mars topographic mapping.

“Kayseri Hançerli Sultan Vakfı Bedesteni” in the Context of the Ottoman Bedestens

Directory of Open Access Journals (Sweden)

Fernaz ÖNCEL

2014-02-01

Full Text Available The deeply-rooted commercial structure tradition of Kayseri is based on the city’s constant and centuries-old role in international trade and commerce. Throughout the Seljuk period, Kayseri’s bazaars were located outside the city walls, in the immediate vicinity of the city. Building of commercial structures in the citadel itself and the centre of the city began during Ottoman times, the period in which the city’s traditional commercial structure began to appear and grow. In 1497, the Sanjak Bey of Kayseri, Mustafa bin Abdulhay, constructed the “Kayseri Hançerli Sultan Vakfı Bedesteni”, surrounded by 38 stores, and thus began the establishment of the commercial fabric of the city. Over time, the Bedesten has changed both physically and functionally. These changes have been for the worse and have led to the Bedesten and its surroundings being defined as an “area of declining trade”. Factors that have negatively affected the structure’s physical make-up include environment, natural disasters, improper restoration, deliberate corruption, and haphazard changes made by users. Economic factors playing a role in its decline include changes to its original function as a ‘shopping’ centre, its traditional customer base, and the type and quality of goods traded there. The Bedesten is discussed here under four headings; Introduction, Bedestens as Ottoman Commercial Structures, Kayseri Hançerli Sultan Wakf Bedesten, Evaluation, and Conclusions.

Full Text Available Blaze-DEMGPU is a modular GPU based discrete element method (DEM framework that supports polyhedral shaped particles. The high level performance is attributed to the light weight and Single Instruction Multiple Data (SIMD that the GPU architecture offers. Blaze-DEMGPU offers suitable algorithms to conduct DEM simulations on the GPU and these algorithms can be extended and modified. Since a large number of scientific simulations are particle based, many of the algorithms and strategies for GPU implementation present in Blaze-DEMGPU can be applied to other fields. Blaze-DEMGPU will make it easier for new researchers to use high performance GPU computing as well as stimulate wider GPU research efforts by the DEM community.

FUSION OF MULTI-SCALE DEMS FROM DESCENT AND NAVCM IMAGES OF CHANG’E-3 USING COMPRESSED SENSING METHOD

Directory of Open Access Journals (Sweden)

M. Peng

2017-07-01

Full Text Available The multi-source DEMs generated using the images acquired in the descent and landing phase and after landing contain supplementary information, and this makes it possible and beneficial to produce a higher-quality DEM through fusing the multi-scale DEMs. The proposed fusion method consists of three steps. First, source DEMs are split into small DEM patches, then the DEM patches are classified into a few groups by local density peaks clustering. Next, the grouped DEM patches are used for sub-dictionary learning by stochastic coordinate coding. The trained sub-dictionaries are combined into a dictionary for sparse representation. Finally, the simultaneous orthogonal matching pursuit (SOMP algorithm is used to achieve sparse representation. We use the real DEMs generated from Chang’e-3 descent images and navigation camera (Navcam stereo images to validate the proposed method. Through the experiments, we have reconstructed a seamless DEM with the highest resolution and the largest spatial coverage among the input data. The experimental results demonstrated the feasibility of the proposed method.

Passive solar energy recovery in non-transparent facades; Passive solare Energiegewinnung im nicht-transparenten Fassadenbereich

Energy Technology Data Exchange (ETDEWEB)

Liersch, K.W. [Brandenburgische Technische Univ. Cottbus (Germany). Lehrstuhl fuer Baukonstruktion und Bauphysik

Evaluation of theoretical and practical studies has shown that non-bearing glass facades of reduced transparency hold a considerable potential for energy recovery. The most important factors governing this process are solar irradiation and inhibition of reflection in the long-wave range. Net energy recovery can be expressed in terms of the decrease of the mean effective heat transmission coefficient. The achievable gains are the smaller the more effective the heat insulating properties of the wall are, i.e. the lower the U-value of the non-transparent wall is. In the case of outer walls with additional heat insulation and a heat transmission coefficient of less than k{sub w} = approx. 0.25 W/ (m-2K) energy recovery is practically negligible, with little scope for improvement through facade orientation. [Deutsch] Die Auswertung der theoretischen und messtechnischen Untersuchungen zeigt, dass mittels einer vorgehaengten, reduziert transparenten Glasfassade betraechtliche Waermegewinne zu erzielen sind. Diese ergeben sich aus der Sonnenzustrahlung sowie der Behinderung langwelliger Waermeabstrahlung. Die Gewinne lassen sich durch eine Abminderung des mittleren effektiven Waermedurchgangskoeffizienten darstellen. Die zu erzielenden Gewinne sind allerdings um so geringer, je besser die sonstige waermeschutztechnische Ausruestung der betreffenden Wand, d.h. je niedriger der k-Wert der nicht-transparenten Wandflaeche ist. Das bedeutet, dass bei Aussenwaenden mit Zusatzdaemmung und einem Waermedurchgangskoeffizienten unterhalb k{sub W}{approx}0,25 W/(m{sup 2}K) der Gewinn nicht mehr nennenswert ist, wobei dann auch die Ausrichtung der Fassade zur Himmelsrichtung das Ergebnis nur noch in geringem Umfang beeinflusst.

Full Text Available Zur Klaerung der Frage, ob der Begriff "Kinoplasma" fuer gewisse, von MERTON (1924,1926, 1930 beobachtete Bildungen an den reifenden Spermiden von pulmonaten Mollusken oder fuer Bestandteile des Cytoplasmas im Sinne von STRASBURGER und SCARTH zu verwenden ist, werden in der vorliegenden Mitteilung die Vorgaenge bei der Spermiohistogenese von Australorbis glabratus olivaceus untersucht. Es ergibt sich: 1. Das von MERTON bezeichnete "Kinoplasma" existiert nicht als solches, es handelt sich bei den von ihm dargestellten Protoplasmabildungen um kugelige, von den Spermiden abgeschnuerte Restkoerper nicht verwendeten Baumaterials, bestehend aus Protoplasma und einigen Mitochondrien. Sie werden von den Naehr- oder Bazalzellen phagozytiert. Der Ausdruck "Kinoplasma" kann nur fuer die submikroskopischen, geformten, faedigen Elemente des Cytoplasmas reserviert bleiben, die den geradlinigen Fall der uebrigen nicht geformten Komponenten bremst oder ablenkt; damit muss das Kinoplasma aber aus dem Begriff des Cytoplasmas herausgenommen werden, da es, wenn auch vermutlich reversibel, eine Differenzierung darstellt. 2. Der Spermienfaden wird von den Centriolen (Axialfilament und den Mitochondrien (zwei peripher gelegene Spiralfilamente, sowie einem Plasmamantel gebildet. 3. Nach Beendigung des Auswachsens der Spermiengeissel, die zu diesem Zeitpunkt nur aus dem Achsenfaden und dem Protoplasmazylinder besteht, setzt sich eine Protoplasmamasse vom Kopf in Richtung zum Geisselende in Bewegung. Sie fuehrt den Golgi-Koerper und sehr viele Mitochondrien mit sich. Aus diesen entwickeln sich Fibrillen, die sich zu den beiden Spiralfilamenten zusammenfuegen. Diese Masse entspricht der von MERTON in seiner Theorie als Kinoplasma bezeichneten Komponente. 4. Die Bewegung dieses Protoplasmateils wird auf den Schub zurueckgefuehrt, den die sich bildenden Fibrillen auf die Mitochondrien ausueben. 5. Die Rueckwaertsbewegung dieses Protoplasmakoerpers beruht wahrscheinlich auf

Die Digitalisierung schreitet mit großen Schritten voran. Dies wirkt sich nicht nur auf die Gesellschaft im Grundsatz, sondern auch auf das Verhalten der Kunden aus. Neue Kommunikationswege beschleunigen die Interaktion zwischen Unternehmen und Verbraucher. Im Vergleich mit großen Internetfirmen werden etablierte Dienstleistungsunternehmen - vom Energieversorger bis zu Versicherungen - stark unter Druck gesetzt, sich noch intensiver mit dem Kundenservice auseinanderzusetzen. Dies wird nur möglich sein, wenn sich die Organisationen entsprechend positionieren und sich frühzeitig auf die Veränderungen einstellen. Hieraus ergeben sich mehr Chancen als Risiken, zumal es nicht nur neue Prozesse, sondern auch neue Berufsbilder geben wird.

J. J. Ruiz

2013-08-01

Full Text Available In this work we evaluated how the use of different positioning systems affects the accuracy of Digital Elevation Models (DEMs generated from aerial imagery obtained with Unmanned Aerial Vehicles (UAVs. In this domain, state-of-the-art DEM generation algorithms suffer from typical errors obtained by GPS/INS devices in the position measurements associated with each picture obtained. The deviations from these measurements to real world positions are about meters. The experiments have been carried out using a small quadrotor in the indoor testbed at the Center for Advanced Aerospace Technologies (CATEC. This testbed houses a system that is able to track small markers mounted on the UAV and along the scenario with millimeter precision. This provides very precise position measurements, to which we can add random noise to simulate errors in different GPS receivers. The results showed that final DEM accuracy clearly depends on the positioning information.

Full Text Available Deleuzes und Guattaris Zurückweisung der Konzeptkunst ist allgemein bekannt und passt so garnicht zur derzeitigen Hegemonie der “post-konzeptionellen” Kunstpraktiken. Genauso unpassend erscheint Deleuzes ontologische und politische Abneigung gegen die Photographie, die „Schnappschüsse“ oder Repräsentationen des Werdens liefert, indem sie Klischeebilder unmittelbar in unserer Gehirne pflanzt, die dann unsere Handlungen und Reaktionen kontrollieren, indem sie uns der Fähigkeit zum kreativen Denken berauben. In Cinema 2 weitet Deleuze diese Argumentation auf das neue “elektronische Bild” aus das, wie auch die Konzeptkunst, die Ebene der Komposition in eine „Schneidetischebene“ oder einen „Bildschirm“ verwandelt, welche Informationen und mit ihnen unsere zu Schnittstellen gewordenen Gehirne einfach nur formatieren. Heutzutage werden Konzeptpraktiken, Photographie und digitale Technologien von der zeitgenössischen Kunst als selbstverständlich angesehen, die auch fröhlich „D&G“ anwendet. Doch verdienen Deleuzes und Guattaris Gedanken nicht eine kritischere Würdigung? Braucht es nicht eine kleinere Kriegsmaschine? Wie sähe die aus im Falle der zeitgenössischen Kunstpraktiken? Unter den diversen Möglichkeiten untersucht der vorliegende Text die sublimen Verzweigungen einer Deuleuzeschen Vorstellung des “Denkens” sowie dessen Position als des „immanent Äußeren“ der post-konzeptionellen Richtung der Kunst

Purpose: In relapsing testicular cancer, additional chemotherapy is followed by abdominal CT. If residual lesions are found, retroperitoneal lymphadenectomy is considered. We studied retrospectively whether morphological criteria can help in selected cases in deciding about lymphadenectomy by distinguishing between vital tumor, scarring and mature teratoma. Methods: In 26 patients who had been treated by salvage chemotherapy and retroperitoneal lymphadenectomy for non-seminomatous testicular cancer between 1990 and 1997, abdominal computed tomography and histology were correlated. Results: Histological examination found scarring in 10 patients, vital tumor in 6, mature teratoma in 4, and simultaneous teratoma and vital tumor in 6. A single CT criterion for distinguishing between these histologies was not identified. In two patients with large masses which were partly cystic and partly solid vital tumor and teratoma were verified. Scarrings may be expected in cystic lesions at the level of the renal hilus which are lined by a thin and smooth wall. Size did not matter. Conclusion: Accurate differentiation between vital tumor and necrosis was not possible. Before lymphadenectomy CT, however, localised lesions. (orig.)

Estimating Horizontal Displacement between DEMs by Means of Particle Image Velocimetry Techniques

2015-12-01

Full Text Available To date, digital terrain model (DTM accuracy has been studied almost exclusively by computing its height variable. However, the largely ignored horizontal component bears a great influence on the positional accuracy of certain linear features, e.g., in hydrological features. In an effort to fill this gap, we propose a means of measurement different from the geomatic approach, involving fluid mechanics (water and air flows or aerodynamics. The particle image velocimetry (PIV algorithm is proposed as an estimator of horizontal differences between digital elevation models (DEM in grid format. After applying a scale factor to the displacement estimated by the PIV algorithm, the mean error predicted is around one-seventh of the cell size of the DEM with the greatest spatial resolution, and around one-nineteenth of the cell size of the DEM with the least spatial resolution. Our methodology allows all kinds of DTMs to be compared once they are transformed into DEM format, while also allowing comparison of data from diverse capture methods, i.e., LiDAR versus photogrammetric data sources.

The purpose of the following chemical simulant studies is to assess the potential acute environmental effects and persistence of diethyl malonate (DEM). Deposition velocities for DEM to soil surfaces ranged from 0.04 to 0.2 cm/sec. For foliar surfaces, deposition velocities ranged from 0.0002 cm/sec at low air concentrations to 0.05 cm/sec for high dose levels. The residence times or half-lives of DEM deposited to soils was 2 h for the fast component and 5 to 16 h for the residual material. DEM deposited to foliar surfaces also exhibited biphasic depuration. The half-life of the short residence time component ranged from 1 to 3 h, while the longer time component had half-times of 16 to 242 h. Volatilization and other depuration mechanisms reduce surface contaminant levels in both soils and foliage to less than 1% of initial dose within 96 h. DEM is not phytotoxic at foliar mass loading levels of less than 10 {mu}m/cm{sup 2}. However, severe damage is evident at mass loading levels in excess of 17 {mu}g/cm{sup 2}. Tall fescue and sagebrush were more affected than was short-needle pine, however, mass loading levels were markedly different. Regrowth of tall fescue indicated that the effects of DEM are residual, and growth rates are affected only at higher mass loadings through the second harvest. Results from in vitro testing of DEM indicated concentrations below 500 {mu}g/g dry soil generally did not negatively impact soil microbial activity. Short-term effects of DEM were more profound on soil dehydrogenase activity than on soil phosphatase activity. No enzyme inhibition or enhancement was observed after 28 days in incubation. Results of the earthworm bioassay indicate survival to be 86 and 66% at soil doses of 107 and 204 {mu}g DEM/cm{sup 2}, respectively. At higher dose level, activity or mobility was judged to be affected in over 50% of the individuals. 21 refs., 10 figs., 15 tabs.

Flood incidents that often occur in Karawang regency need to be mitigated. These expectations exist on technologies that can predict, anticipate and reduce disaster risks. Flood modeling techniques using Digital Elevation Model (DEM) data can be applied in mitigation activities. High accuracy DEM data used in modeling, will result in better flooding flood models. The result of high accuracy DEM data processing will yield information about surface morphology which can be used to identify indication of flood hazard area. The purpose of this study was to identify and describe flood hazard areas by identifying wetland areas using DEM data and Landsat-8 images. TerraSAR-X high-resolution data is used to detect wetlands from landscapes, while land cover is identified by Landsat image data. The Topography Wetness Index (TWI) method is used to detect and identify wetland areas with basic DEM data, while for land cover analysis using Tasseled Cap Transformation (TCT) method. The result of TWI modeling yields information about potential land of flood. Overlay TWI map with land cover map that produces information that in Karawang regency the most vulnerable areas occur flooding in rice fields. The spatial accuracy of the flood hazard area in this study was 87%.

How large is the Upper Indus Basin? The pitfalls of auto-delineation using DEMs

Extraction of watershed areas from Digital Elevation Models (DEMs) is increasingly required in a variety of environmental analyses. It is facilitated by the availability of DEMs based on remotely sensed data, and by Geographical Information System (GIS) software. However, accurate delineation depends on the quality of the DEM and the methodology adopted. This paper considers automated and supervised delineation in a case study of the Upper Indus Basin (UIB), Pakistan, for which published estimates of the basin area show significant disagreement, ranging from 166,000 to 266,000 km2. Automated delineation used ArcGIS Archydro and hydrology tools applied to three good quality DEMs (two from SRTM data with 90m resolution, and one from 30m resolution ASTER data). Automatic delineation defined a basin area of c.440,000 km2 for the UIB, but included a large area of internal drainage in the western Tibetan Plateau. It is shown that discrepancies between different estimates reflect differences in the initial extent of the DEM used for watershed delineation, and the unchecked effect of iterative pit-filling of the DEM (going beyond the filling of erroneous pixels to filling entire closed basins). For the UIB we have identified critical points where spurious addition of catchment area has arisen, and use Google Earth to examine the geomorphology adjacent to these points, and also examine the basin boundary data provided by the HydroSHEDS database. We show that the Pangong Tso watershed and some other areas in the western Tibetan plateau are not part of the UIB, but are areas of internal drainage. Our best estimate of the area of the Upper Indus Basin (at Besham Qila) is 164,867 km2 based on the SRTM DEM, and 164,853 km2 using the ASTER DEM). This matches the catchment area measured by WAPDA SWHP. An important lesson from this investigation is that one should not rely on automated delineation, as iterative pit-filling can produce spurious drainage networks and basins, when

Full Text Available Erzählungen können absichtlich die Unwahrheit verbreiten. Ob der Autor bzw. die Autorin selbst der Lüge bezichtigt werden kann oder sollte, hängt allerdings nicht nur davon ab, wie man Lüge definiert, sondern auch davon, welchen Status man der Erzählung zuschreibt: Worin unterscheidet sich der Wahrheitsanspruch fiktionaler Äußerungen in literarischen Texten von dem faktualen Erzählens? Kann Fiktion lügen? Eva-Maria Konrad plädiert nach einer Auseinandersetzung mit Genettes Studie zu Paratexten dafür, vom Autor verantwortete Vorworte in literarischen Texten nicht generell als fiktionale Äußerungen zu betrachten – unter bestimmten Voraussetzungen, so Konrad, könnten daher auch Herausgeberfiktionen als Lügen bezeichnet werden. Jochen Mecke hingegen argumentiert, dass fiktionale Literatur nie lügen kann, da jede Zuschreibung von Aufrichtigkeit an literarische Texte auf jenem Pakt zwischen Leser(in und Autor(in basiert, den Samuel Taylor Coleridge als „willing suspension of disbelief“ bezeichnet hat. Entscheidend ist dabei, so Mecke, nicht die Fiktivität der erzählten Ereignisse, sondern die Fiktionalität der Aussageinstanz.

A pair of SAR images acquired from different positions can be used to generate digital elevation model (DEM). Two techniques exploiting this characteristic have been introduced: stereo SAR and interferometric SAR. They permit to recover the third dimension (topography) and, at the same time, to identify the absolute position (geolocation) of pixels included in the imaged area, thus allowing the generation of DEMs. In this paper, StereoSAR and InSAR combined adjustment model are constructed, and unify DEM extraction from InSAR and StereoSAR into the same coordinate system, and then improve three dimensional positioning accuracy of the target. We assume that there are four images 1, 2, 3 and 4. One pair of SAR images 1,2 meet the required conditions for InSAR technology, while the other pair of SAR images 3,4 can form stereo image pairs. The phase model is based on InSAR rigorous imaging geometric model. The master image 1 and the slave image 2 will be used in InSAR processing, but the slave image 2 is only used in the course of establishment, and the pixels of the slave image 2 are relevant to the corresponding pixels of the master image 1 through image coregistration coefficient, and it calculates the corresponding phase. It doesn't require the slave image in the construction of the phase model. In Range-Doppler (RD) model, the range equation and Doppler equation are a function of target geolocation, while in the phase equation, the phase is also a function of target geolocation. We exploit combined adjustment model to deviation of target geolocation, thus the problem of target solution is changed to solve three unkonwns through seven equations. The model was tested for DEM extraction under spaceborne InSAR and StereoSAR data and compared with InSAR and StereoSAR methods respectively. The results showed that the model delivered a better performance on experimental imagery and can be used for DEM extraction applications.

Experimental and theoretical investigations were made in order to define the main influencing parameters of gap flow and secondary flow in compressor cascades. The investigations and results are presented in detail. [German] Im Rahmen des FVV-Forschungsvorhabens 'Randstroemung in Verdichtergittern' wurden am Institut fuer Strahlantriebe der Universitaet der Bundeswehr Muenchen umfangreiche experimentelle und theoretische Untersuchungen zur Bestimmung der wesentlichen Einflussgroessen auf die Spalt- und Sekundaerstroemung in Verdichtergittern durchgefuehrt. Als Parameter wurden die Spaltweite, das Schaufelseitenverhaeltnis mit Schaufelhoehe und Sehnenlaenge, die aerodynamische Belastung und die Zustroemgrenzschichtdicke variiert. Zur Analyse der Stroemungsvorgaenge wurden Fuenflochsonden-Stroemungsfeldtraversierungen, Profil- und Seitenwanddruckverteilungsmessungen und Laser-Zwei-Fokus-Messungen im Spalt herangezogen. Die experimentellen Untersuchungen zeigen eine komplexe Wechselwirkung zwischen Spalt- und Kanalwirbel. Die Spalt- und Sekundaerverluste steigen mit der Spaltweite und der aerodynamischen Belastung, wobei der Anstieg eine welchselseitige Abhaengigkeit der Parameter aufweist. Gegenueber dem Schaufelseitenverhaeltnis verhalten sich die Spalt- und Sekundaerverluste umgekehrt proportional. Die Zustroemgrenzschicht beeinflusst zwar den Verlust- und Abstroemwinkelverlauf ueber der Schaufelhoehe, jedoch nicht die sich abzueglich des Profil- und Zustroemverlustes ergebenden Spalt- und Sekundaerverluste. Die verwendeten 3D Stroemungsberechnungsverfahren erfassen die Stroemungsphaenomene qualitativ gut, wobei der Spaltmodellierung eine besondere Rolle zukommt. Die realistische Spaltmodellierung erlaubt einen sehr detaillierten Einblick in das Stroemungsgeschehen im Spalt. Die Verlustberechnung erweist sich jedoch als sehr unsicher. Auf der Grundlage einer umfangreichen Literaturanalyse wurden die verfuegbaren Korrelationen zur Berechnung des Spaltverlustes und

Granular dynamics, contact mechanics and particle system simulations a DEM study

CERN Document Server

Thornton, Colin

2015-01-01

This book is devoted to the Discrete Element Method (DEM) technique, a discontinuum modelling approach that takes into account the fact that granular materials are composed of discrete particles which interact with each other at the microscale level. This numerical simulation technique can be used both for dispersed systems in which the particle-particle interactions are collisional and compact systems of particles with multiple enduring contacts. The book provides an extensive and detailed explanation of the theoretical background of DEM. Contact mechanics theories for elastic, elastic-plastic, adhesive elastic and adhesive elastic-plastic particle-particle interactions are presented. Other contact force models are also discussed, including corrections to some of these models as described in the literature, and important areas of further research are identified. A key issue in DEM simulations is whether or not a code can reliably simulate the simplest of systems, namely the single particle oblique impact wit...

DemQSAR: predicting human volume of distribution and clearance of drugs.

In silico methods characterizing molecular compounds with respect to pharmacologically relevant properties can accelerate the identification of new drugs and reduce their development costs. Quantitative structure-activity/-property relationship (QSAR/QSPR) correlate structure and physico-chemical properties of molecular compounds with a specific functional activity/property under study. Typically a large number of molecular features are generated for the compounds. In many cases the number of generated features exceeds the number of molecular compounds with known property values that are available for learning. Machine learning methods tend to overfit the training data in such situations, i.e. the method adjusts to very specific features of the training data, which are not characteristic for the considered property. This problem can be alleviated by diminishing the influence of unimportant, redundant or even misleading features. A better strategy is to eliminate such features completely. Ideally, a molecular property can be described by a small number of features that are chemically interpretable. The purpose of the present contribution is to provide a predictive modeling approach, which combines feature generation, feature selection, model building and control of overtraining into a single application called DemQSAR. DemQSAR is used to predict human volume of distribution (VD(ss)) and human clearance (CL). To control overtraining, quadratic and linear regularization terms were employed. A recursive feature selection approach is used to reduce the number of descriptors. The prediction performance is as good as the best predictions reported in the recent literature. The example presented here demonstrates that DemQSAR can generate a model that uses very few features while maintaining high predictive power. A standalone DemQSAR Java application for model building of any user defined property as well as a web interface for the prediction of human VD(ss) and CL is

On the COSMO-SkyMed Exploitation for Interferometric DEM Generation

DEM products for Earth observation space-borne applications are being to play a role of increasing importance due to the new generation of high resolution sensors (both optical and SAR). These new sensors demand elevation data for processing and, on the other hand, they provide new possibilities for DEM generation. Till now, for what concerns interferometric DEM, the Shuttle Radar Topography Mission (SRTM) has been the reference product for scientific applications all over the world. SRTM mission [1] had the challenging goal to meet the requirements for a homogeneous and reliable DEM fulfilling the DTED-2 specifications. However, new generation of high resolution sensors (including SAR) pose new requirements for elevation data in terms of vertical precision and spatial resolution. DEM are usually used as ancillary input in different processing steps as for instance geocoding and Differential SAR Interferometry. In this context, the recent SAR missions of DLR (TerraSAR-X and TanDEM-X) and ASI (COSMO-SkyMed) can play a promising role thanks to their high resolution both in space and time. In particular, the present work investigates the potentialities of the COSMO/SkyMed (CSK) constellation for ground elevation measurement with particular attention devoted to the impact of the improved spatial resolution wrt the previous SAR sensors. The recent scientific works, [2] and [3], have shown the advantages of using CSK in the monitoring of terrain deformations caused by landslides, earthquakes, etc. On the other hand, thanks to the high spatial resolution, CSK appears to be very promising in monitoring man-made structures, such as buildings, bridges, railways and highways, thus enabling new potential applications (urban applications, precise DEM, etc.). We present results obtained by processing both SPOTLIGHT and STRIPMAP acquisitions through standard SAR Interferometry as well as multi-pass interferometry [4] with the aim of measuring ground elevation.

TecDEM is a MATLAB based tool box for understanding the tectonics from digital elevation models (DEMs) of any area. These DEMs can be derived from data of any spatial resolution (Low, medium and High). In the first step we extract drainage network from the DEMs using flow grid approach. Drainage network is a group of streams having elevation and catchment area information as a function of spatial locations. We implement an array of stream structure to study this drainage network. Knickpoints can be identified on each stream of the drainage network by a graphical user interface and are helpful for understanding stream morphology. Stream profile analysis in steady state condition is applied on all streams to calculate geomorphic parameters and regional uplift rates. Hack index is calculated for all the profiles at a certain interval and over the change of knickpoints. Reports menu of this tool box generates detailed statistics report, complete tabulated report, graphical output of each analyzed stream profile and Hack index profile. All the calculated values are part of stream structure and is saved as .mat file for later use with this tool box. The spatial distribution of geomorphic parameters, uplift rates and knickpoints are exported as a shape files for visualization in professional GIS software. We test this tool box on DEMs from different tectonic settings worldwide and received verifiable results with other studies.

SAR interferometry has long been regarded as an effective tool for wide-area topographic mapping in hilly and mountainous areas. However, quality of InSAR DEM product is usually affected by atmospheric disturbances and decorrelation-induced voids, especially for data acquired in repeat-pass mode. In this paper, we proposed an approach for improved topographic mapping by optimal fusion of multi-orbit InSAR DEMs with correction of atmospheric phase screen (APS). An experimental study with highresolution TerraSAR-X and COSMO-SkyMed datasets covering a mountainous area was carried out to demonstrate the effectiveness of the proposed approach. Validation with a reference DEM of scale 1:50,000 indicated that vertical accuracy of the fused DEM can be better than 5 m.

SAR interferometry has long been regarded as an effective tool for wide-area topographic mapping in hilly and mountainous areas. However, quality of InSAR DEM product is usually affected by atmospheric disturbances and decorrelation-induced voids, especially for data acquired in repeat-pass mode. In this paper, we proposed an approach for improved topographic mapping by optimal fusion of multi-orbit InSAR DEMs with correction of atmospheric phase screen (APS). An experimental study with highresolution TerraSAR-X and COSMO-SkyMed datasets covering a mountainous area was carried out to demonstrate the effectiveness of the proposed approach. Validation with a reference DEM of scale 1:50,000 indicated that vertical accuracy of the fused DEM can be better than 5 m.

Die Veränderung der Energiewirtschaft schreitet kontinuierlich voran - und wird mit Gesetz zur Digitalisierung der Energiewende nicht abgeschlossen sein. Vielmehr steigen die Innovationsgeschwindigkeit und die Erwartungshaltung der Kunden. Dieses Kapitel beschreibt, wie intelligente Messsysteme die Basis für neue Möglichkeiten schaffen und wie sich diese Veränderungen auf die Wertschöpfung auswirken. Der Fokus liegt dabei auf dem Wandel der einzelnen Wertschöpfungsstufen im Verlauf der Liberalisierung des Messwesens und dem seit dem 02.09.2016 verbindlichen Messstellenbetriebsgesetzes. Der Beitrag zeigt auf, wie sich bisher getrennte Wertschöpfungsstufen nunmehr direkt berühren und miteinander interagieren. Deutlich wird dadurch, wie Informationen zu Mehrwert führen können - aber auch, welche Fragen noch zu beantworten sind und welche Hürden es zu überwinden gilt.

The second flight of Focusing Optics X-ray Solar Imager (FOXSI) sounding rocket experiment was successfully completed on 11 December 2014. FOXSI makes direct imaging and spectral observation of the Sun in hard X-rays using grazing incidence optics modules which focus X-rays onto seven focal plane detectors kept at a 2m distance, in the energy range 4 to 20 keV, to study particle acceleration and coronal heating. Significant HXR emissions were observed by FOXSI during microflare events with A0.5 and A2.5 class, as classified by GOES, that occurred during FOXSI-2 flight.Spectral analysis of FOXSI data for these events indicate presence of plasma at higher temperatures (>10MK). We attempt to study the plasma content in the corona at different temperatures, characterized by the differential emission measure (DEM), over the FOXSI-2 observed flare regions using the Atmospheric Imaging Assembly (SDO/AIA) data. We utilize AIA observations in different EUV filters that are sensitive to ionized iron lines, to determine the DEM by using a regularized inversion method. This poster will show the properties of hot plasma as derived from FOXSI-2 HXR spectra with supporting DEM analysis using AIA observations.

Zhenming Shi

2015-06-01

Full Text Available The distinct element method (DEM incorporated with a novel bond contact model was applied in this paper to shed light on the microscopic physical origin of macroscopic behaviors of weathered rock, and to achieve the changing laws of microscopic parameters from observed decaying properties of rocks during weathering. The changing laws of macroscopic mechanical properties of typical rocks were summarized based on the existing research achievements. Parametric simulations were then conducted to analyze the relationships between macroscopic and microscopic parameters, and to derive the changing laws of microscopic parameters for the DEM model. Equipped with the microscopic weathering laws, a series of DEM simulations of basic laboratory tests on weathered rock samples was performed in comparison with analytical solutions. The results reveal that the relationships between macroscopic and microscopic parameters of rocks against the weathering period can be successfully attained by parametric simulations. In addition, weathering has a significant impact on both stress–strain relationship and failure pattern of rocks.

A Novel DEM Approach to Simulate Block Propagation on Forested Slopes

Toe, David; Bourrier, Franck; Dorren, Luuk; Berger, Frédéric

2018-03-01

In order to model rockfall on forested slopes, we developed a trajectory rockfall model based on the discrete element method (DEM). This model is able to take the complex mechanical processes at work during an impact into account (large deformations, complex contact conditions) and can explicitly simulate block/soil, block/tree contacts as well as contacts between neighbouring trees. In this paper, we describe the DEM model developed and we use it to assess the protective effect of different types of forest. In addition, we compared it with a more classical rockfall simulation model. The results highlight that forests can significantly reduce rockfall hazard and that the spatial structure of coppice forests has to be taken into account in rockfall simulations in order to avoid overestimating the protective role of these forest structures against rockfall hazard. In addition, the protective role of the forests is mainly influenced by the basal area. Finally, the advantages and limitations of the DEM model were compared with classical rockfall modelling approaches.

Three 3.6 m long cable-in-conduit conductors based on both NbTi and Nb3Sn, developed by different manufacturers, suitable for the central solenoid and toroidal field coils of ITER, have been tested so far. This paper presents the results of extensive measurements of critical current and current sharing temperature of the Nb3Sn conductors in the 8 - 11 T range for temperatures between 4.5 K and 11 K. Voltage versus current curves have been analyzed with respect to the n value. The manufacturing of a high quality joint between two Nb3Sn conductors after heat treatment is reported, together with some measurements of the joint resistance.

Ozdemir, Adnan

2011-07-01

SummaryThe purpose of this study is to produce a groundwater spring potential map of the Sultan Mountains in central Turkey, based on a logistic regression method within a Geographic Information System (GIS) environment. Using field surveys, the locations of the springs (440 springs) were determined in the study area. In this study, 17 spring-related factors were used in the analysis: geology, relative permeability, land use/land cover, precipitation, elevation, slope, aspect, total curvature, plan curvature, profile curvature, wetness index, stream power index, sediment transport capacity index, distance to drainage, distance to fault, drainage density, and fault density map. The coefficients of the predictor variables were estimated using binary logistic regression analysis and were used to calculate the groundwater spring potential for the entire study area. The accuracy of the final spring potential map was evaluated based on the observed springs. The accuracy of the model was evaluated by calculating the relative operating characteristics. The area value of the relative operating characteristic curve model was found to be 0.82. These results indicate that the model is a good estimator of the spring potential in the study area. The spring potential map shows that the areas of very low, low, moderate and high groundwater spring potential classes are 105.586 km 2 (28.99%), 74.271 km 2 (19.906%), 101.203 km 2 (27.14%), and 90.05 km 2 (24.671%), respectively. The interpretations of the potential map showed that stream power index, relative permeability of lithologies, geology, elevation, aspect, wetness index, plan curvature, and drainage density play major roles in spring occurrence and distribution in the Sultan Mountains. The logistic regression approach has not yet been used to delineate groundwater potential zones. In this study, the logistic regression method was used to locate potential zones for groundwater springs in the Sultan Mountains. The evolved model

A coupled DEM-CFD method for impulse wave modelling

Zhao, Tao; Utili, Stefano; Crosta, GiovanBattista

2015-04-01

Rockslides can be characterized by a rapid evolution, up to a possible transition into a rock avalanche, which can be associated with an almost instantaneous collapse and spreading. Different examples are available in the literature, but the Vajont rockslide is quite unique for its morphological and geological characteristics, as well as for the type of evolution and the availability of long term monitoring data. This study advocates the use of a DEM-CFD framework for the modelling of the generation of hydrodynamic waves due to the impact of a rapid moving rockslide or rock-debris avalanche. 3D DEM analyses in plane strain by a coupled DEM-CFD code were performed to simulate the rockslide from its onset to the impact with still water and the subsequent wave generation (Zhao et al., 2014). The physical response predicted is in broad agreement with the available observations. The numerical results are compared to those published in the literature and especially to Crosta et al. (2014). According to our results, the maximum computed run up amounts to ca. 120 m and 170 m for the eastern and western lobe cross sections, respectively. These values are reasonably similar to those recorded during the event (i.e. ca. 130 m and 190 m respectively). In these simulations, the slope mass is considered permeable, such that the toe region of the slope can move submerged in the reservoir and the impulse water wave can also flow back into the slope mass. However, the upscaling of the grains size in the DEM model leads to an unrealistically high hydraulic conductivity of the model, such that only a small amount of water is splashed onto the northern bank of the Vajont valley. The use of high fluid viscosity and coarse grain model has shown the possibility to model more realistically both the slope and wave motions. However, more detailed slope and fluid properties, and the need for computational efficiency should be considered in future research work. This aspect has also been

2017-06-01

The use of the Discrete Element Method (DEM) for industrial civil engineering industrial applications is currently limited due to the computational demands when large numbers of particles are considered. The graphics processing unit (GPU) with its highly parallelized hardware architecture shows potential to enable solution of civil engineering problems using discrete granular approaches. We demonstrate in this study the pratical utility of a validated GPU-enabled DEM modeling environment to simulate industrial scale granular problems. As illustration, the flow discharge of storage silos using 8 and 17 million particles is considered. DEM simulations have been performed to investigate the influence of particle size (equivalent size for the 20/40-mesh gravel) and induced shear stress for two hopper shapes. The preliminary results indicate that the shape of the hopper significantly influences the discharge rates for the same material. Specifically, this work shows that GPU-enabled DEM modeling environments can model industrial scale problems on a single portable computer within a day for 30 seconds of process time.

Simulation of TanDEM-X interferograms for urban change detection

Welte, Amelie; Hammer, Horst; Thiele, Antje; Hinz, Stefan

2017-10-01

Damage detection after natural disasters is one of the remote sensing tasks in which Synthetic Aperture Radar (SAR) sensors play an important role. Since SAR is an active sensor, it can record images at all times of day and in all weather conditions, making it ideally suited for this task. While with the newer generation of SAR satellites such as TerraSAR-X or COSMOSkyMed amplitude change detection has become possible even for urban areas, interferometric phase change detection has not been published widely. This is mainly because of the long revisit times of common SAR sensors leading to temporal decorrelation. This situation has changed dramatically with the advent of the TanDEM-X constellation, which can create single-pass interferograms from space at very high resolutions, avoiding temporal decorrelation almost completely. In this paper the basic structures that are present for any building in InSAR phases, i.e. layover, shadow, and roof areas, are examined. Approaches for their extraction from TanDEM-X interferograms are developed using simulated SAR interferograms. The extracted features of the building signature will in the future be used for urban change detection in real TanDEM-X High Resolution Spotlight interferograms.

Landform classification using a sub-pixel spatial attraction model to increase spatial resolution of digital elevation model (DEM

2018-04-01

Full Text Available The purpose of the present study is preparing a landform classification by using digital elevation model (DEM which has a high spatial resolution. To reach the mentioned aim, a sub-pixel spatial attraction model was used as a novel method for preparing DEM with a high spatial resolution in the north of Darab, Fars province, Iran. The sub-pixel attraction models convert the pixel into sub-pixels based on the neighboring pixels fraction values, which can only be attracted by a central pixel. Based on this approach, a mere maximum of eight neighboring pixels can be selected for calculating of the attraction value. In the mentioned model, other pixels are supposed to be far from the central pixel to receive any attraction. In the present study by using a sub-pixel attraction model, the spatial resolution of a DEM was increased. The design of the algorithm is accomplished by using a DEM with a spatial resolution of 30 m (the Advanced Space borne Thermal Emission and Reflection Radiometer; (ASTER and a 90 m (the Shuttle Radar Topography Mission; (SRTM. In the attraction model, scale factors of (S = 2, S = 3, and S = 4 with two neighboring methods of touching (T = 1 and quadrant (T = 2 are applied to the DEMs by using MATLAB software. The algorithm is evaluated by taking the best advantages of 487 sample points, which are measured by surveyors. The spatial attraction model with scale factor of (S = 2 gives better results compared to those scale factors which are greater than 2. Besides, the touching neighborhood method is turned to be more accurate than the quadrant method. In fact, dividing each pixel into more than two sub-pixels decreases the accuracy of the resulted DEM. On the other hand, in these cases DEM, is itself in charge of increasing the value of root-mean-square error (RMSE and shows that attraction models could not be used for S which is greater than 2. Thus considering results, the proposed model is highly capable of

Automatic relative RPC image model bias compensation through hierarchical image matching for improving DEM quality

Science.gov (United States)

Noh, Myoung-Jong; Howat, Ian M.

2018-02-01

The quality and efficiency of automated Digital Elevation Model (DEM) extraction from stereoscopic satellite imagery is critically dependent on the accuracy of the sensor model used for co-locating pixels between stereo-pair images. In the absence of ground control or manual tie point selection, errors in the sensor models must be compensated with increased matching search-spaces, increasing both the computation time and the likelihood of spurious matches. Here we present an algorithm for automatically determining and compensating the relative bias in Rational Polynomial Coefficients (RPCs) between stereo-pairs utilizing hierarchical, sub-pixel image matching in object space. We demonstrate the algorithm using a suite of image stereo-pairs from multiple satellites over a range stereo-photogrammetrically challenging polar terrains. Besides providing a validation of the effectiveness of the algorithm for improving DEM quality, experiments with prescribed sensor model errors yield insight into the dependence of DEM characteristics and quality on relative sensor model bias. This algorithm is included in the Surface Extraction through TIN-based Search-space Minimization (SETSM) DEM extraction software package, which is the primary software used for the U.S. National Science Foundation ArcticDEM and Reference Elevation Model of Antarctica (REMA) products.

In a previous work, the addition of basic screened Coulombic electrostatic forces to an existing commercial discrete element modeling (DEM) software was reported. Triboelectric experiments were performed to charge glass spheres rolling on inclined planes of various materials. Charge generation constants and the Q/m ratios for the test materials were calculated from the experimental data and compared to the simulation output of the DEM software. In this paper, we will discuss new values of the charge generation constants calculated from improved experimental procedures and data. Also, planned work to include dielectrophoretic, Van der Waals forces, and advanced mechanical forces into the software will be discussed.

Israelische Public Diplomacy und ihre Wahrnehmung durch deutsche Journalisten

2014-07-01

Full Text Available Public Diplomacy stellt insbesondere für Staaten in internationalen Konflikten wie Israel ein wichtiges Kommunikationsinstrument dar, um ausländische Bevölkerungen zu erreichen. Der Artikel zeigt die Ergebnisse einer Studie, in der untersucht wurde, wie die israelische Public Diplomacy von deutschen Journalisten aufgenommen und verarbeitet wird. Journalisten kommt dabei eine Schlüsselrolle als Mittler zwischen dem israelischen Staat und der deutschen Bevölkerung zu. In Anlehnung an den Katalog der Public Diplomacy-Maßnahmen von Gilboa (2006 wurde die Relevanz einzelner Maßnahmen für Journalisten erfragt. Die Ergebnisse zeigen, dass persönliche Kontakte für Journalisten nach wie vor eine wichtige Quelle darstellen und nicht von Cyber-Public Diplomacy ersetzt werden können. Staatliche Public Diplomacy wird zwar wahrgenommen, jedoch wird ihre Objektivität bezweifelt, während NGOs und Stiftungen als vertrauenswürdiger eingestuft werden. Des Weiteren wird Israel in der Öffentlichkeit nach wie vor dominierend mit dem Nahostkonflikt identifiziert, was sich nach Meinung der befragten Journalisten auch in Zukunft nicht durch gezielte Öffentlichkeitsarbeit verhindern lässt.

Full Text Available Stellen wir uns vor, der Mann vom Lande in Kafkas Parabel „Vor dem Gesetz“ sei nicht, wie es in der vorschnellen Rollenfixierung zahlreicher Kafka‐Interpretationen heißt, das menschliche Individuum, das der Gewalt der institutionalisierten Gesetzlichkeit (der Macht, der Moral, der Religion etc. ausgeliefert ist. Er sei stattdessen ein Richter „vom Lande“, einer der draußen im Lande einen Rechtsfall nach Recht und Gesetz zu behandeln hat und der nun in seinen Entscheidungsqualen mit dem Gesetz nicht zu Recht kommt. Let us imagine that the man from the country in Kafka’s parable “Before the law” is not the human individual who has been delivered up to the force of institutionalised legalism (power, morality, religion etc, as we find in numerous Kafka interpretations with their somewhat over‐hasty role fixation. Let us suppose instead that he is a judge “from the country”, who – back there, in the country – has to deal with a legal case according to the law, and who now, in the torment of decision‐making, cannot find what is right according to the law.

Full Text Available In welchem Umfang können die Leute des Altertums von Achäologen verstanden werden? Wir wählen zum Titel des Aufsatzes einen Teil der Inschrift vom ACO-Becher aus Virunum (jetzt im Landesmuseum Klagenfurt, da wir ein Thema über die materielle Kultur aus der Römerzeit bearbeiten. Die Römerzeit ist nämlich die älteste Periode in der Geschichte des östlichen Alpen- und nordadriatischen Raums, so auch Sloweniens, und zeugt auch durch direkte schriftliche Quellen von sich selbst. So kann das Verfolgen der Tatsachen, wie gewisse Erscheinungsformen an Artefakten durch die archäologische Forschung verstanden sind, besonders aufregend werden. Wir richten unsere Aufmerksamkeit auf drei Beispiele, die in vergangenen Jahrzehnten durch Publikation etwas mehr ins Blickfeld geraten sind. Auch Trinkgefäße befinden sich darunter. An erster Stelle ist die Rede vom glirarium - dem töpfernen »Käfig« für Siebenschläfer - von Poetovio (heute Ptuj, Slowenien. Das Gefäß wurde als Graburne im (späten 2. Jh. verwendet. Zu dieser Art von Verwendung wurde in den bisherigen Bearbeitungen nur einmal Stellung genommen (Mikl Curk 1986 und die Vermutung geäußert, man habe zur Zeit der Grablegung möglicherweise den wahren Zweck des Gefäßes nicht mehr gekannt. Doch heute wird eine neue Deutung vorgeschlagen: Beim Vorkommen eines solchen Gefäßes im Grab soll es sich um ein Symbol handeln. Dieses Symbol soll, mit gewissen weiteren aus den römischen Brandgräbern in Slowenien essbaren Grabbeigaben (Muscheln, Schnecken, den Gedanken an das - unter der Erscheinung des Todes - schlummernde Leben darstellen. Die verschlossenen Muschel- und Schneckenschalen haben ja die Form eines leblosen Steines, so wie auch der Siebenschläfer während des Winterschlafes tot zu sein scheint.

Use of DEMs Derived from TLS and HRSI Data for Landslide Feature Recognition

Directory of Open Access Journals (Sweden)

Maurizio Barbarella

2018-04-01

Full Text Available This paper addresses the problems arising from the use of data acquired with two different remote sensing techniques—high-resolution satellite imagery (HRSI and terrestrial laser scanning (TLS—for the extraction of digital elevation models (DEMs used in the geomorphological analysis and recognition of landslides, taking into account the uncertainties associated with DEM production. In order to obtain a georeferenced and edited point cloud, the two data sets require quite different processes, which are more complex for satellite images than for TLS data. The differences between the two processes are highlighted. The point clouds are interpolated on a DEM with a 1 m grid size using kriging. Starting from these DEMs, a number of contour, slope, and aspect maps are extracted, together with their associated uncertainty maps. Comparative analysis of selected landslide features drawn from the two data sources allows recognition and classification of hierarchical and multiscale landslide components. Taking into account the uncertainty related to the map enables areas to be located for which one data source was able to give more reliable results than another. Our case study is located in Southern Italy, in an area known for active landslides.

Investigation of origin, subsurface processes and reservoir temperature of geothermal springs around Koh-i-Sultan volcano, Chagai, Pakistan

International Nuclear Information System (INIS)

Ahmad, M.; Rafique, M.; Iqbal, N.; Fazil, M.

2009-07-01

In Chagai area, seven springs with maximum surface temperature of 32.2 deg. C located in the vicinity of Miri Crater of Koh-i-Sultan Volcano were investigated using isotope and chemical techniques. Two springs of Padagi Kaur are MgSO/sub 4/ type, while all the other springs at Batal Kaur, Miri Kaur and Chigin Dik are Na-Cl type. Alteration of water to SO/sub 4/ type takes place by absorption of magmatic H/sub 2/S and the acidic solution is further responsible to dissolve rock salt and carbonate minerals. EC increases from Padagi springs (4940 and 8170 S/cm) to Chigin Dik springs (45600 S/cm). Chagai thermal manifestations receive recharge from meteoric waters in the vicinity of Padagi Kaur (east side of Miri Crater), which is heated by the hot magma chamber of Koh-i-Sultan most probably through deep circulation. Movement of the thermal water is from Miri Crater towards Chigin Dik area. Residence time is more than 60 years. The thermal waters do not have any contribution of shallow young groundwater and they have high 1/sup 8/O-shift (6 to 8%) due to rock-water interaction. Reservoir temperatures estimated by different chemical geo thermometers like Na-K, Na-K-Ca, Na-K-Mg 1/2 (triangular plot) are quite high (200-300 deg. C), while the silica and (SO/sub 4/-H/sub 2/O) geo thermometers give relatively low temperature ranges (107-144 deg. C and 112-206 deg. C respectively). (author)

High-accuracy single-pass InSAR DEM for large-scale flood hazard applications

Science.gov (United States)

Schumann, G.; Faherty, D.; Moller, D.

2017-12-01

In this study, we used a unique opportunity of the GLISTIN-A (NASA airborne mission designed to characterizing the cryosphere) track to Greenland to acquire a high-resolution InSAR DEM of a large area in the Red River of the North Basin (north of Grand Forks, ND, USA), which is a very flood-vulnerable valley, particularly in spring time due to increased soil moisture content near state of saturation and/or, typical for this region, snowmelt. Having an InSAR DEM that meets flood inundation modeling and mapping requirements comparable to LiDAR, would demonstrate great application potential of new radar technology for national agencies with an operational flood forecasting mandate and also local state governments active in flood event prediction, disaster response and mitigation. Specifically, we derived a bare-earth DEM in SAR geometry by first removing the inherent far range bias related to airborne operation, which at the more typical large-scale DEM resolution of 30 m has a sensor accuracy of plus or minus 2.5 cm. Subsequently, an intelligent classifier based on informed relationships between InSAR height, intensity and correlation was used to distinguish between bare-earth, roads or embankments, buildings and tall vegetation in order to facilitate the creation of a bare-earth DEM that would meet the requirements for accurate floodplain inundation mapping. Using state-of-the-art LiDAR terrain data, we demonstrate that capability by achieving a root mean squared error of approximately 25 cm and further illustrating its applicability to flood modeling.

A new DEM of the Austfonna ice cap by combining differential SAR interferometry with ICESat laser altimetry

Directory of Open Access Journals (Sweden)

Geir Moholdt

2012-05-01

Full Text Available We present a new digital elevation model (DEM of the Austfonna ice cap in the Svalbard Archipelago, Norwegian Arctic. Previous DEMs derived from synthetic aperture radar (SAR and optical shape-from-shading have been tied to airborne radio echo-sounding surface profiles from 1983 which contain an elevation-dependent bias of up to several tens of metres compared with recent elevation data. The new and freely available DEM is constructed purely from spaceborne remote sensing data using differential SAR interferometry (DInSAR in combination with ICESat laser altimetry. Interferograms were generated from pairs of SAR scenes from the one-day repeat tandem phase of the European Remote Sensing Satellites 1/2 (ERS-1/2 in 1996. ICESat elevations from winter 2006–08 were used as ground control points to refine the interferometric baseline. The resulting DEM is validated against the same ground control points and independent surface elevation profiles from Global Navigation Satellite Systems (GNSS and airborne laser altimetry, yielding root mean square (RMS errors of about 10 m in all cases. This quality is sufficient for most glaciological applications, and the new DEM will be a baseline data set for ongoing and future research at Austfonna. The technique of combining satellite DInSAR with high-resolution satellite altimetry for DEM generation might also be a good solution in other glacier regions with similar characteristics, especially when data from TanDEM-X and CryoSat-2 become available.

The new German Recycling and Waste management Act (KrWG). Chances and perspectives for the secondary raw materials industry; Das neue Kreislaufwirtschaftsgesetz. Chancen und Perspektiven fuer die Sekundaerrohrstoffwirtschaft

After long discussions concerning wordings, the new German Act on Recycling and Waste Management (KrWG) came into force with the decision of the arbitration panel of 8 February 2012 and the agreement of the German Bundestag and Bundesrat. It took more than two years from the first draft to the new act, and discussions and lawsuits can be expected to continue. The new act still follows the structure of its predecessor, but private industries, especially medium-sized ones, have not been given sufficient scope for action. Politicians were unable to find a fair balance between private and communal interests. Now, with the introduction of a new standard recycling bin, the legislator is held to take account of the interests of the private waste management industry, whose labour and innovative power made a decisive contribution to the success of waste management and recycling in Germany. (orig.) [German] Der letzte Schlusspunkt ist nach zaehem Ringen um einzelne Formulierungen des Kreislaufwirtschaftsgesetzes (KrWG) mit dem Beschluss des Vermittlungsausschusses am 8. Februar 2012 und mit der anschliessenden Zustimmung des Deutschen Bundestages sowie des Bundesrates gesetzt worden. Damit sind seit dem ersten Arbeitsentwurf des Bundesministeriums fuer die Novellierung des Kreislaufwirtschafts- und Abfallrechts mehr als zwei Jahre vergangen, und es bedarf keiner hellseherischen Faehigkeiten um vorherzusagen, dass die Auseinandersetzung ueber einzelne Bestimmungen und nachrangige Verordnungen des Gesetzes vor Gericht und in der Politik noch lange nicht ihren Abschluss gefunden hat. Trotz aller Diskussionen waehrend des Gesetzgebungsverfahrens sind die wesentlichen Grundstrukturen des alten Kreislaufwirtschafts- und Abfallgesetzes auch im neuen KrWG erhalten geblieben. Der Privatwirtschaft, vor allem in der Breite aus vielen mittelstaendischen Unternehmen bestehend, ist jedoch nicht genuegend Handlungsspielraum gewaehrt worden. Der Politik ist es nicht gelungen, einen fairen

To identify the river buffalo chromosome carrying the genes coding for GAPD, TPI1, and LDHB, karyotypic examination was carried out on 14 buffalo-hamster hybrid clones previously tested for presence of this syntenic group. In cattle, this group (U3) has been assigned to chromosome 5, which is assumed to be homologous to the long arm of buffalo chromosome 4. Chromosome 4 was present in all five clones expressing the three enzymes, and absent in all seven negative clones, indicating that in the buffalo GAPD, TPI1, and LDHB are located on chromosome 4. One clone, expressing GAPD and TPI1, but not LDHB, was found to carry a translocation between hamster marker chromosome M(2) and buffalo 4q1 → 4qter. In another clone, expressing LDHB, but not GAPD and TPI1, chromosome 4 was absent, while a very small, unidentifiable acrocentric was present. These observations suggest that LDHB is located in the proximal part of 4q1, and that GAPD and TPI1 are located more distally, in 4q1 → 4q2. ZUSAMMENFASSUNG: Lokalisierung von Genen auf Chromosom 4 des Flußbüffels durch Büffel-Hamster-Hybridzellen Zur Identifikation von Flußbüffelchromosomen mit Genen für GAPD, TPI1 und LDHB wurden Karyotypenbestimmungen an 14 Büffel-Hamster-Hybridklonen durchgeführt, die vorher auf Anwesenheit der betreffenden synthenischen Gruppen geprüft worden waren.

Oil as a design parameter in screw-type engines - use of non-newtonian oils. Pt. 1; Oel als Konstruktionselement in Schraubenmaschinen - Einsatz nicht newtonscher Oele. T. 1

The model of the calculation of the friction losses caused by oil described in this report delivers a starting point for the integration of the design parameter `oil` for oil injected screw-type engines. The use of non newtonian oils with a shear thinning behaviour lead to a decrease of energy consumption over a broad speed range of screw-type compressors. The decrease is mainly caused by the shear indicated lower viscosity in the clearances of the compressor. A difficulty through the use of this oils is the estimation of the conditions in the clearances. The rate of shear in the single clearance is influenced by the relative speed of the boundaries and by the height of the clearance during operation. Up to now only cold heights were used in the model. To improve the quality of the model the clearances of a running screw compressor were measured. The losses which were determined at the screw compressor test plant are the summation of all losses including the losses caused by the power transmission and in the bearings. Experiments at a model rotor test stand make the determination of the friction losses and the losses by the acceleration of the oil in the clearances possible. A better calculation model shall deliver the conditions to describe the influence of the oil on the energy efficiency and to define the optimal oil for every screw compressor. (orig.)

Hadrosauroid Dinosaurs from the Late Cretaceous of the Sultanate of Oman.

Full Text Available Fragmentary post-cranial remains (femora, tibia, vertebrae of ornithischian dinosaurs from the Late Cretaceous of the Sultanate of Oman are described and referred to hadrosauroids. The specimens come from the Al-Khod Conglomerate, of latest Campanian to Maastrichtian age, in the north-eastern part of the country. Although the fragmentary condition of the fossils precludes a precise identification, various characters, including the shape of the fourth trochanter of the femur and the morphology of its distal end, support an attribution to hadrosauroids. With the possible exception of a possible phalanx from Angola, this group of ornithopod dinosaurs, which apparently originated in Laurasia, was hitherto unreported from the Afro-Arabian plate. From a paleobiogeographical point of view, the presence of hadrosauroids in Oman in all likelihood is a result of trans-Tethys dispersal from Asia or Europe, probably by way of islands in the Tethys shown on all recent paleogeographical maps of that area. Whether hadrosauroids were widespread on the Afro-Arabian landmass in the latest Cretaceous, or where restricted to the « Oman island » shown on some paleogeographical maps, remains to be determined.

2014-02-01

The objectives of this study were to assess the attitude of Omani nursing students towards writing-to-learn (WTL) and its relationship to demographic variables, self-efficacy and the writing process. A cross-sectional design was used to evaluate attitudes towards WTL by Sultan Qaboos University nursing students. A convenience sample of 106 students was used and data collected between October 2009 and March 2010. A modified version of the WTL attitude scale developed by Dobie and Poirrier was used to collect the data. Descriptive and inferential statistics were used for analysis. Senior and junior students had more positive attitudes to WTL than mid-level students who tended to have negative attitudes towards writing. Although 52.8% students had negative attitudes towards the writing process, the median was higher for attitudes to the writing process compared to the median for self-efficacy. There was a positive correlation between self-efficacy and writing process scores. Overall, students had negative attitudes towards WTL. Attitudes are learnt or formed through previous experiences. The incorporation of WTL strategies into teaching can transform students' negative attitudes towards writing into positive ones.

Soil-tire system interaction is a fundamental and important research topic in terramechanics. We applied a 2D finite element, discrete element method (FE-DEM), using FEM for the tire and the bottom soil layer and DEM for the surface soil layer. Satisfactory performance analysis was achieved. In this study, to clarify the capabilities and limitations of the method for soil-tire interaction analysis, the tractive performance of real automobile tires with two different tread patterns—smooth and grooved—was analyzed by FE-DEM, and the numerical results compared with the experimental results obtained using an indoor traction measurement system. The analysis of tractive performance could be performed with sufficient accuracy by the proposed 2D dynamic FE-DEM. FE-DEM obtained larger drawbar pull for a tire with a grooved tread pattern, which was verified by the experimental results. Moreover, the result for the grooved tire showed almost the same gross tractive effort and similar running resistance as in experiments. However, for a tire with smooth tread pattern, the analyzed gross tractive effort and running resistance behaved differently than the experimental results, largely due to the difference in tire sinkage in FE-DEM.

High-resolution and up-to-date topographic data are of high value in volcanology and can be used in a variety of applications such as volcanic flow modeling or hazard assessment. Furthermore, time-series of topographic data can provide valuable insights into the dynamics of an ongoing eruption. Differencing topographic data acquired at different times enables to derive areal coverage of lava, flow volumes, and lava extrusion rates, the most important parameters during ongoing eruptions for estimating hazard potential, yet most difficult to determine. Anyhow, topographic data acquisition and provision is a challenge. Very often, high-resolution data only exists within a small spatial extension, or the available data is already outdated when the final product is provided. This is especially true for very dynamic landscapes, such as volcanoes. The bistatic TanDEM-X radar satellite mission enables for the first time to generate up-to-date and high-resolution digital elevation models (DEMs) repeatedly using the interferometric phase. The repeated acquisition of TanDEM-X data facilitates the generation of a time-series of DEMs. Differencing DEMs generated from bistatic TanDEM-X data over time can contribute to monitor topographic changes at active volcanoes, and can help to estimate magmatic ascent rates. Here, we use the bistatic TanDEM-X data to investigate the activity of Etna volcano in Sicily, Italy. Etna's activity is characterized by lava fountains and lava flows with ash plumes from four major summit crater areas. Especially the newest crater, the New South East Crater (NSEC) that was formed in 2011 has been highly active in recent years. Over one hundred bistatic TanDEM-X data pairs were acquired between January 2011 and March 2017 in StripMap mode, covering episodes of lava fountaining and lava flow emplacement at Etna's NSEC and its surrounding area. Generating DEMs of every bistatic data pair enables us to assess areal extension of the lava flows, to

Full Text Available Purpose: This pilot study sought to determine the efficacy of using the Developmental Eye Movement (DEM test in the adult, acquired brain injury (ABI population to quantify clinically the effects of controlled, laboratory-performed, oculomotor-based vision therapy/vision rehabilitation. Methods: Nine adult subjects with mild traumatic brain injury (mTBI and five with stroke were assessed before and after an eight-week, computer-based, versional oculomotor (fixation, saccades, pursuit, and simulated reading training program (9.6 h total. The protocol incorporated a cross-over, interventional design with and without the addition of auditory feedback regarding two-dimensional eye position. The clinical outcome measure was the Developmental Eye Movement (DEM test score (ratio, errors taken before, midway, and immediately following training. Results: For the DEM ratio parameter, improvements were found in 80–89% of the subjects. For the DEM error parameter, improvements were found in 100% of the subjects. Incorporation of the auditory feedback component revealed a trend toward enhanced performance. The findings were similar for both DEM parameters, as well as for incorporation of the auditory feedback, in both diagnostic groups. Discussion: The results of the present study demonstrated considerable improvements in the DEM test scores following the oculomotor-based training, thus reflecting more time-optimal and accurate saccadic tracking after the training. The DEM test should be considered as another clinical test of global saccadic tracking performance in the ABI population.

INTRIGUES BEHIND THE HAREM WALL: SOCIAL, CULTURAL AND POLITICAL CONSTRUCTION OF LIFE BEHIND THE HAREM OF SULTAN SULAIMAN I

Directory of Open Access Journals (Sweden)

Eka Hendry Ar.

2015-12-01

Full Text Available The urgency of exploring the history of the harem is important, not only because of being a rare phenomenon today or no longer in existence but perhaps this work is like opening the pandora’s box, a nightmare for women. This paper is presented as an academic review to portrait the fact that power is always in contact with wealth and attractive women, especially during a period when patriarchy was dominant. Sultan Sulaiman I was in power between 1520 to 1566 AD, in the 16th century AD. In western literature, Sultan Sulaiman was known as Suleyman the Magnificent. The work concludes, first, that the harem to the people of the Middle East in the medieval times was considered respectable for the family, especially for women both in the context of the imperial and domestic harem, where it was constructed in the name of honor, comfort and safety for women. Second, the construction of social, cultural and religious institutions of harem is the integration between the will to protect and maintain the honor of women, the concept of marriage in Islam and the patriarchal system hegemony in the Islamic world particularly in the context of the imperial harem. Third, the role of Sulaiman I who was “brave” to go against the tradition that had been practiced for many years in the Ottoman Empire, a milestone was important for the emancipation of women of the harem. Finally, to respond to the harem tradition, we must be in an impartial position, between the construction of the West and East.

Recently in the Sultanate of Oman, there has been a rapid surge of coastal developments. These developments cause metal contamination, which may affect the habitats and communities at and near the coastal region. As a result, a study was conducted to assess the level of metal contamination and its impact on the marine sediments in the vicinity of the Single Buoy Moorings 3 (SBM3) at Mina Al Fahal in the Sultanate of Oman. Marine subtidal sediment samples were collected from six different stations of the SBM3 for the period ranging from June 2009 to April 2010. These samples were then analyzed for their level and distribution of the heavy metals of cadmium (Cd), copper (Cu), lead (Pb) and vanadium (V). Overall, low concentrations of all four heavy metals were measured from the marine sediments, indicating that the marine at SBM3 is of good quality. Copyright © 2014 Elsevier Ltd.

Uncertainty modelling and analysis of volume calculations based on a regular grid digital elevation model (DEM)

Science.gov (United States)

Li, Chang; Wang, Qing; Shi, Wenzhong; Zhao, Sisi

2018-05-01

The accuracy of earthwork calculations that compute terrain volume is critical to digital terrain analysis (DTA). The uncertainties in volume calculations (VCs) based on a DEM are primarily related to three factors: 1) model error (ME), which is caused by an adopted algorithm for a VC model, 2) discrete error (DE), which is usually caused by DEM resolution and terrain complexity, and 3) propagation error (PE), which is caused by the variables' error. Based on these factors, the uncertainty modelling and analysis of VCs based on a regular grid DEM are investigated in this paper. Especially, how to quantify the uncertainty of VCs is proposed by a confidence interval based on truncation error (TE). In the experiments, the trapezoidal double rule (TDR) and Simpson's double rule (SDR) were used to calculate volume, where the TE is the major ME, and six simulated regular grid DEMs with different terrain complexity and resolution (i.e. DE) were generated by a Gauss synthetic surface to easily obtain the theoretical true value and eliminate the interference of data errors. For PE, Monte-Carlo simulation techniques and spatial autocorrelation were used to represent DEM uncertainty. This study can enrich uncertainty modelling and analysis-related theories of geographic information science.

Full Text Available The paper presents a conceptual micromechanical model for 1-D compression behaviour of non-active clays in saturated state. An experimental investigation was carried out on kaolin clay samples saturated with fluids of different pH and dielectric permittivity. The effect of pore fluid characteristics on one-dimensional compressibility behaviour of kaolin was investigated. A three dimensional Discrete Element Method (DEM was implemented in order to simulate the response of saturated kaolin observed during the experiments. A complex contact model was introduced, considering both the mechanical and physico-chemical microscopic interactions between clay particles. A simple analysis with spherical particles only was performed as a preliminary step in the DEM study in the elastic regime.

Coastal Digital Elevation Models (DEMs) for tsunami hazard assessment on the French coasts

2015-04-01

Building precise and up-to-date coastal DEMs is a prerequisite for accurate modeling and forecasting of hydrodynamic processes at local scale. Marine flooding, originating from tsunamis, storm surges or waves, is one of them. Some high resolution DEMs are being generated for multiple coast configurations (gulf, embayment, strait, estuary, harbor approaches, low-lying areas…) along French Atlantic and Channel coasts. This work is undertaken within the framework of the TANDEM project (Tsunamis in the Atlantic and the English ChaNnel: Definition of the Effects through numerical Modeling) (2014-2017). DEMs boundaries were defined considering the vicinity of French civil nuclear facilities, site effects considerations and potential tsunamigenic sources. Those were identified from available historical observations. Seamless integrated topographic and bathymetric coastal DEMs will be used by institutions taking part in the study to simulate expected wave height at regional and local scale on the French coasts, for a set of defined scenarii. The main tasks were (1) the development of a new capacity of production of DEM, (2) aiming at the release of high resolution and precision digital field models referred to vertical reference frameworks, that require (3) horizontal and vertical datum conversions (all source elevation data need to be transformed to a common datum), on the basis of (4) the building of (national and/or local) conversion grids of datum relationships based on known measurements. Challenges in coastal DEMs development deal with good practices throughout model development that can help minimizing uncertainties. This is particularly true as scattered elevation data with variable density, from multiple sources (national hydrographic services, state and local government agencies, research organizations and private engineering companies) and from many different types (paper fieldsheets to be digitized, single beam echo sounder, multibeam sonar, airborne laser

Calibration of DEM parameters on shear test experiments using Kriging method

Science.gov (United States)

Xavier, Bednarek; Sylvain, Martin; Abibatou, Ndiaye; Véronique, Peres; Olivier, Bonnefoy

2017-06-01

Calibration of powder mixing simulation using Discrete-Element-Method is still an issue. Achieving good agreement with experimental results is difficult because time-efficient use of DEM involves strong assumptions. This work presents a methodology to calibrate DEM parameters using Efficient Global Optimization (EGO) algorithm based on Kriging interpolation method. Classical shear test experiments are used as calibration experiments. The calibration is made on two parameters - Young modulus and friction coefficient. The determination of the minimal number of grains that has to be used is a critical step. Simulations of a too small amount of grains would indeed not represent the realistic behavior of powder when using huge amout of grains will be strongly time consuming. The optimization goal is the minimization of the objective function which is the distance between simulated and measured behaviors. The EGO algorithm uses the maximization of the Expected Improvement criterion to find next point that has to be simulated. This stochastic criterion handles with the two interpolations made by the Kriging method : prediction of the objective function and estimation of the error made. It is thus able to quantify the improvement in the minimization that new simulations at specified DEM parameters would lead to.

The problem of DEM models calibration is considered in the article. It is proposed to divide models input parameters into those that require iterative calibration and those that are recommended to measure directly. A new method for model calibration based on the design of the experiment for iteratively calibrated parameters is proposed. The experiment is conducted using a specially designed stand. The results are processed with technical vision algorithms. Approximating functions are obtained and the error of the implemented software and hardware complex is estimated. The prospects of the obtained results are discussed.

Full Text Available Mainul Haque, Nor Iza A Rahman, Zainal Zulkifli, Salwani Ismail Faculty of Medicine, Universiti Sultan Zainal Abidin, Kuala Terengganu, Terengganu, Malaysia Abstract: The innovation of penicillin by Dr Alexander Fleming in 1928 and its use in clinical practice saved many lives, especially during the Second World War. Tuberculosis still carries a significant public health threat and has re-emerged over the past two decades, even in modern countries where tuberculosis was thought to be eliminated. The World Health Organization defines antimicrobial resistance as the resistance of a microorganism to an antimicrobial drug that was initially effective for treatment of infections caused by the microbe. Therefore, the findings of the current study will provide data to enable the design of a new educational program to better equip our students in confronting antimicrobial resistance. This study was a cross-sectional, questionnaire-based survey, which was undertaken in the Faculty of Medicine, Universiti Sultan Zainal Abidin, Kuala Terengganu, Malaysia. The study participants were students of the Bachelor of Medicine and Bachelor of Surgery program (MBBS of Year III, IV, and V. A total of 142 out of 164 (86% medical students returned the questionnaire. Specifically, the year-wise breakdown of responses was 29% (41, 39% (55, and 32% (45 for Year III, IV, and V, respectively. Among the study respondents, 28% (40 were male, and the remaining 72% (102 were female. In all, 67% of the participants felt more confident in “making an accurate diagnosis of infection/sepsis.” The majority (88% of the study participants stated that they would like more training on antibiotic selection. This research has found that there is a gap between theoretical input and clinical practice; the students are demanding more educational intervention to face the threat of antimicrobial resistance.

SULTAN test facility for large-scale vessel coolability in natural convection at low pressure

International Nuclear Information System (INIS)

Rouge, S.

1997-01-01

The SULTAN facility (France/CEA/CENG) was designed to study large-scale structure coolability by water in boiling natural convection. The objectives are to measure the main characteristics of two-dimensional, two-phase flow, in order to evaluate the recirculation mass flow in large systems, and the limits of the critical heat flux (CHF) for a wide range of thermo-hydraulic (pressure, 0.1-0.5 MPa; inlet temperature, 50-150 C; mass flow velocity, 5-4400 kg s -1 m -2 ; flux, 100-1000 kW m -2 ) and geometric (gap, 3-15 cm; inclination, 0-90 ) parameters. This paper makes available the experimental data obtained during the first two campaigns (90 , 3 cm; 10 , 15 cm): pressure drop differential pressure (DP) = f(G), CHF limits, local profiles of temperature and void fraction in the gap, visualizations. Other campaigns should confirm these first results, indicating a favourable possibility of the coolability of large surfaces under natural convection. (orig.)

Rockslide and Impulse Wave Modelling in the Vajont Reservoir by DEM-CFD Analyses

Zhao, T.; Utili, S.; Crosta, G. B.

2016-06-01

This paper investigates the generation of hydrodynamic water waves due to rockslides plunging into a water reservoir. Quasi-3D DEM analyses in plane strain by a coupled DEM-CFD code are adopted to simulate the rockslide from its onset to the impact with the still water and the subsequent generation of the wave. The employed numerical tools and upscaling of hydraulic properties allow predicting a physical response in broad agreement with the observations notwithstanding the assumptions and characteristics of the adopted methods. The results obtained by the DEM-CFD coupled approach are compared to those published in the literature and those presented by Crosta et al. (Landslide spreading, impulse waves and modelling of the Vajont rockslide. Rock mechanics, 2014) in a companion paper obtained through an ALE-FEM method. Analyses performed along two cross sections are representative of the limit conditions of the eastern and western slope sectors. The max rockslide average velocity and the water wave velocity reach ca. 22 and 20 m/s, respectively. The maximum computed run up amounts to ca. 120 and 170 m for the eastern and western lobe cross sections, respectively. These values are reasonably similar to those recorded during the event (i.e. ca. 130 and 190 m, respectively). Therefore, the overall study lays out a possible DEM-CFD framework for the modelling of the generation of the hydrodynamic wave due to the impact of a rapid moving rockslide or rock-debris avalanche.

Full Text Available Demência pode ser definida como uma síndrome caracterizada pelo declínio progressivo e global de memória e outras funções cognitivas. O presente trabalho é uma revisão bibliográfica que tem como objetivo identificar e apresentar a produção científica relacionada com a temática. O levantamento bibliográfico foi nas Bases de Dados da Biblioteca Virtual de Saúde - BIREME. Os tipos de demência aqui levadas em conta são: Demência de Alzheimer, Demência por Corpos de Lewy (DCL, Demência Frontotemporal (DFT e Demência Vascular. Nas demências, os fatores de risco variam de acordo com os estressores genéticos e ambientais, além da idade e histórico clínico, conforme cada indivíduo. As principais alterações cerebrais são: placas senis e emaranhados neurofibrilares, com comprometimento da neurotransmissão colinérgica e atrofia cerebral extensa. Na sua maior parte são patologias de início insidioso e deterioração progressiva. O primeiro sinal/sintoma é a perda da memória seguida de declínio cognitivo e funcional. Podem ser divididas em estágios conforme o acometimento. O diagnóstico é realizado por meio de história clínica, exames laboratoriais e de neuroimagem, exame clínico neurológico e exames neuropsicológicos. Conclui-se que ainda não se tem a cura das demências e que os estudos de células-tronco podem contribuir nesse sentido.

Extraction and Validation of Geomorphological Features from EU-DEM in The Vicinity of the Mygdonia Basin, Northern Greece

2017-12-01

The European Union Digital Elevation Model (EU-DEM) is a relatively new, hybrid elevation product, principally based on SRTM DEM and ASTER GDEM data, but also on publically available Russian topographic maps for regions north of 60° N. More specifically, EU-DEM is a Digital Surface Model (DSM) over Europe from the Global Monitoring for Environment and Security (GMES) Reference Data Access (RDA) project - a realisation of the Copernicus (former GMES) programme, managed by the European Commission/DG Enterprise and Industry. Even if EU-DEM is indeed more reliable in terms of elevation accuracy than its constituents, it ought to be noted that it is not representative of the original elevation measurements, but is rather a secondary (mathematical) product. Therefore, for specific applications, such as those of geomorphological interest, artefacts may be induced. To this end, the purpose of this paper is to investigate the performance of EU-DEM for geomorphological applications and compare it against other available datasets, i.e. topographic maps and (almost) global DEMs such as SRTM, ASTER-GDEM and WorldDEM™. This initial investigation is carried out in Central Macedonia, Northern Greece, in the vicinity of the Mygdonia basin, which corresponds to an area of particular interest for several geoscience applications. This area has also been serving as a test site for the systematic validation of DEMs for more than a decade. Consequently, extensive elevation datasets and experience have been accumulated over the years, rendering the evaluation of new elevation products a coherent and useful exercise on a local to regional scale. In this context, relief classification, drainage basin delineation, slope and slope aspect, as well as extraction and classification of drainage network are performed and validated among the aforementioned elevation sources. The achieved results focus on qualitative and quantitative aspects of automatic geomorphological feature extraction from

An Optimal DEM Reconstruction Method for Linear Array Synthetic Aperture Radar Based on Variational Model

Directory of Open Access Journals (Sweden)

Shi Jun

2015-02-01

Full Text Available Downward-looking Linear Array Synthetic Aperture Radar (LASAR has many potential applications in the topographic mapping, disaster monitoring and reconnaissance applications, especially in the mountainous area. However, limited by the sizes of platforms, its resolution in the linear array direction is always far lower than those in the range and azimuth directions. This disadvantage leads to the blurring of Three-Dimensional (3D images in the linear array direction, and restricts the application of LASAR. To date, the research on 3D SAR image enhancement has focused on the sparse recovery technique. In this case, the one-to-one mapping of Digital Elevation Model (DEM brakes down. To overcome this, an optimal DEM reconstruction method for LASAR based on the variational model is discussed in an effort to optimize the DEM and the associated scattering coefficient map, and to minimize the Mean Square Error (MSE. Using simulation experiments, it is found that the variational model is more suitable for DEM enhancement applications to all kinds of terrains compared with the Orthogonal Matching Pursuit (OMPand Least Absolute Shrinkage and Selection Operator (LASSO methods.

Full Text Available Topography and land cover characteristics can have significant effects on infiltration, runoff, and erosion processes on watersheds. The ability to model the timing and routing of surface water and erosion is affected by the resolution of the digital elevation model (DEM. High resolution ground-based Light Detecting and Ranging (LiDAR technology can be used to collect detailed topographic and land cover characteristic data. In this study, a method was developed to remove vegetation from ground-based LiDAR data to create high resolution DEMs. Research was conducted on intensively studied rainfall–runoff plots on the USDA-ARS Walnut Gulch Experimental Watershed in Southeast Arizona. LiDAR data were used to generate 1 cm resolution digital surface models (DSM for 5 plots. DSMs created directly from LiDAR data contain non-surface objects such as vegetation cover. A vegetation removal method was developed which used a slope threshold and a focal mean filter method to remove vegetation and create bare earth DEMs. The method was validated on a synthetic plot, where rocks and vegetation were added incrementally. Results of the validation showed a vertical error of ±7.5 mm in the final DEM.

2015-05-01

Full Text Available It is difficult to estimate the Doppler frequency and modulating rate for airborne SAR by using traditional vector method due to instable flight and complex terrain. In this paper, it is qualitatively analyzed that the impacts of POS, DEM and their errors on airborne SAR Doppler parameters. Then an innovative vector method is presented based on the range-coplanarity equation to estimate the Doppler centroid taking the POS and DEM as auxiliary data. The effectiveness of the proposed method is validated and analyzed via the simulation experiments. The theoretical analysis and experimental results show that the method can be used to estimate the Doppler centroid with high accuracy even in the cases of high relief, instable flight, and large squint SAR.

These data were derived from the original Digital Elevation Models (DEMs) produced by the Boreal Ecosystem-Atmosphere Study (BOREAS) Hydrology (HYD)-8 team. The original DEMs were in the Universal Transverse Mercator (UTM) projection, while this product is projected in the Albers Equal-Area Conic (AEAC) projection. The pixel size of the data is 100 meters, which is appropriate for the 1:50,000-scale contours from which the DEMs were made. The original data were compiled from information available in the 1970s and 1980s. This data set covers the two Modeling Sub-Areas (MSAs) that are contained within the Southern Study Area (SSA) and the Northern Study Area (NSA). The data are stored in binary, image format files. The DEM data over the NSA-MSA and SSA-MSA in the AEAC projection are available from the Earth Observing System Data and Information System (EOSDIS) Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC). The data files are available on a CD-ROM (see document number 20010000884).

A new 100-m Digital Elevation Model of the Antarctic Peninsula derived from ASTER Global DEM: methods and accuracy assessment

Directory of Open Access Journals (Sweden)

A. J. Cook

2012-10-01

Full Text Available A high resolution surface topography Digital Elevation Model (DEM is required to underpin studies of the complex glacier system on the Antarctic Peninsula. A complete DEM with better than 200 m pixel size and high positional and vertical accuracy would enable mapping of all significant glacial basins and provide a dataset for glacier morphology analyses. No currently available DEM meets these specifications. We present a new 100-m DEM of the Antarctic Peninsula (63–70° S, based on ASTER Global Digital Elevation Model (GDEM data. The raw GDEM products are of high-quality on the rugged terrain and coastal-regions of the Antarctic Peninsula and have good geospatial accuracy, but they also contain large errors on ice-covered terrain and we seek to minimise these artefacts. Conventional data correction techniques do not work so we have developed a method that significantly improves the dataset, smoothing the erroneous regions and hence creating a DEM with a pixel size of 100 m that will be suitable for many glaciological applications. We evaluate the new DEM using ICESat-derived elevations, and perform horizontal and vertical accuracy assessments based on GPS positions, SPOT-5 DEMs and the Landsat Image Mosaic of Antarctica (LIMA imagery. The new DEM has a mean elevation difference of −4 m (± 25 m RMSE from ICESat (compared to −13 m mean and ±97 m RMSE for the original ASTER GDEM, and a horizontal error of less than 2 pixels, although elevation accuracies are lower on mountain peaks and steep-sided slopes. The correction method significantly reduces errors on low relief slopes and therefore the DEM can be regarded as suitable for topographical studies such as measuring the geometry and ice flow properties of glaciers on the Antarctic Peninsula. The DEM is available for download from the NSIDC website: http://nsidc.org/data/nsidc-0516.html (Fusion of space-borne multi-baseline and multi-frequency interferometric results based on extended Kalman filter to generate high quality DEMs

Repeat-pass Interferometric Synthetic Aperture Radar (InSAR) is a technique that can be used to generate DEMs. But the accuracy of InSAR is greatly limited by geometrical distortions, atmospheric effect, and decorrelations, particularly in mountainous areas, such as western China where no high quality DEM has so far been accomplished. Since each of InSAR DEMs generated using data of different frequencies and baselines has their own advantages and disadvantages, it is therefore very potential to overcome some of the limitations of InSAR by fusing Multi-baseline and Multi-frequency Interferometric Results (MMIRs). This paper proposed a fusion method based on Extended Kalman Filter (EKF), which takes the InSAR-derived DEMs as states in prediction step and the flattened interferograms as observations in control step to generate the final fused DEM. Before the fusion, detection of layover and shadow regions, low-coherence regions and regions with large height error is carried out because MMIRs in these regions are believed to be unreliable and thereafter are excluded. The whole processing flow is tested with TerraSAR-X and Envisat ASAR datasets. Finally, the fused DEM is validated with ASTER GDEM and national standard DEM of China. The results demonstrate that the proposed method is effective even in low coherence areas.

All you need is shape: Predicting shear banding in sand with LS-DEM

Kawamoto, Reid; Andò, Edward; Viggiani, Gioacchino; Andrade, José E.

2018-02-01

This paper presents discrete element method (DEM) simulations with experimental comparisons at multiple length scales-underscoring the crucial role of particle shape. The simulations build on technological advances in the DEM furnished by level sets (LS-DEM), which enable the mathematical representation of the surface of arbitrarily-shaped particles such as grains of sand. We show that this ability to model shape enables unprecedented capture of the mechanics of granular materials across scales ranging from macroscopic behavior to local behavior to particle behavior. Specifically, the model is able to predict the onset and evolution of shear banding in sands, replicating the most advanced high-fidelity experiments in triaxial compression equipped with sequential X-ray tomography imaging. We present comparisons of the model and experiment at an unprecedented level of quantitative agreement-building a one-to-one model where every particle in the more than 53,000-particle array has its own avatar or numerical twin. Furthermore, the boundary conditions of the experiment are faithfully captured by modeling the membrane effect as well as the platen displacement and tilting. The results show a computational tool that can give insight into the physics and mechanics of granular materials undergoing shear deformation and failure, with computational times comparable to those of the experiment. One quantitative measure that is extracted from the LS-DEM simulations that is currently not available experimentally is the evolution of three dimensional force chains inside and outside of the shear band. We show that the rotations on the force chains are correlated to the rotations in stress principal directions.

Diagnostic of the temperature and differential emission measure (DEM based on Hinode/XRT data

Full Text Available We discuss here various methodologies and an optimal strategy of the temperature and emission measure diagnostics based on Hinode X-Ray Telescope data. As an example of our results we present the determination of the temperature distribution of the X-rays emitting plasma using a filters ratio method and three various methods of the calculation of the differential emission measure (DEM. We have found that all these methods give results similar to the two filters ratio method. Additionally, all methods of the DEM calculation gave similar solutions. We can state that the majority of the pairs of the Hinode filters allows one to derive the temperature and emission measure in the isothermal plasma approximation using standard diagnostics based on the two filters ratio method. In cases of strong flares one can also expect good conformity of the results obtained using a Withbroe – Sylwester, genetic algorithm and least-squares methods of the DEM evaluation.

The Focusing Optics X-ray Solar Imager (FOXSI) sounding rocket makes directimaging and spectral observation of the Sun in hard X-rays (HXRs) using highlysensitive focusing HXR optics. The second flight of FOXSI was launchedsuccessfully on 11 December 2014 and observed significant HXR emissions duringmicroflares. Some of these flares showed heating up to severalmillion Kelvin and were visible in the Extreme Ultraviolet (EUV) with the AtmosphericImaging Assembly (SDO/AIA). Spectral observations from FOXSI suggest emission upto 10-12 MK. We utilize SDO/AIA EUV, Hinode/XRT soft X-ray, and FOXSI-2 highenergy X-ray observations to derive the differential emission measure (DEM) ofthe microflares. The AIA and XRT observations provide broad temperaturecoverage but are poorly constrained at the hotter end. We therefore use FOXSI-2to better determine the high temperature component, thus producing a moreconstrained DEM than is possible with typically available observations. We usethis more highly constrained DEM to investigate the energetics of the observedmicroflares.

3D DEM analyses of the 1963 Vajont rock slide

2013-04-01

The 1963 Vajont rock slide has been modelled using the distinct element method (DEM). The open-source DEM code, YADE (Kozicki & Donzé, 2008), was used together with the contact detection algorithm proposed by Boon et al. (2012). The critical sliding friction angle at the slide surface was sought using a strength reduction approach. A shear-softening contact model was used to model the shear resistance of the clayey layer at the slide surface. The results suggest that the critical sliding friction angle can be conservative if stability analyses are calculated based on the peak friction angles. The water table was assumed to be horizontal and the pore pressure at the clay layer was assumed to be hydrostatic. The influence of reservoir filling was marginal, increasing the sliding friction angle by only 1.6˚. The results of the DEM calculations were found to be sensitive to the orientations of the bedding planes and cross-joints. Finally, the failure mechanism was investigated and arching was found to be present at the bend of the chair-shaped slope. References Boon C.W., Houlsby G.T., Utili S. (2012).

DEM Simulation of Biaxial Compression Experiments of Inherently Anisotropic Granular Materials and the Boundary Effects

Directory of Open Access Journals (Sweden)

Zhao-Xia Tong

2013-01-01

Full Text Available The reliability of discrete element method (DEM numerical simulations is significantly dependent on the particle-scale parameters and boundary conditions. To verify the DEM models, two series of biaxial compression tests on ellipse-shaped steel rods are used. The comparisons on the stress-strain relationship, strength, and deformation pattern of experiments and simulations indicate that the DEM models are able to capture the key macro- and micromechanical behavior of inherently anisotropic granular materials with high fidelity. By using the validated DEM models, the boundary effects on the macrodeformation, strain localization, and nonuniformity of stress distribution inside the specimens are investigated using two rigid boundaries and one flexible boundary. The results demonstrate that the boundary condition plays a significant role on the stress-strain relationship and strength of granular materials with inherent fabric anisotropy if the stresses are calculated by the force applied on the wall. However, the responses of the particle assembly measured inside the specimens are almost the same with little influence from the boundary conditions. The peak friction angle obtained from the compression tests with flexible boundary represents the real friction angle of particle assembly. Due to the weak lateral constraints, the degree of stress nonuniformity under flexible boundary is higher than that under rigid boundary.

In 21 horses with the anamnesis backproblems there had been a clinical, scan- and X-ray-examination of the thoracal and lumbar vertebra in special consideration of the spinosus process and the dorsal intervertebral joint. But there was not always a relation between the clinical signs and X-rays or scan results. Not all positive X-rays found their corresponding scan activity and not all scan activities took place in X-rays. In many cases there was pathological change of the spinosus process and arthropathy of the dorsal intervertebral joint at the same time. Only with X-raying it is not possible to decide to operate the thoracolumbal, interspinale syndrom (TIS) or not [German] Bei 2l Pferden mit dem Vorbericht 'Rückenleiden' wurden klinisch, röntgenologisch und szintigraphisch die Brust- und Lendenwirbelsäule unter besonderer Berücksichtigung der Dornfortsätze und der dorsalen Intervertebralgelenke untersucht.

Effect of DEM resolution and comparison between different weighting factors for hydrologic connectivity index

Science.gov (United States)

Cantreul, Vincent; Cavalli, Marco; Degré, Aurore

2016-04-01

The emerging concept of hydrological connectivity is difficult to quantify. Some indices have been proposed. The most cited is Borselli's one. It mainly uses the DEM as input. The pixel size may strongly impacts the result of the calculation. It has not been studied yet in silty areas. Another important aspect is the choice of the weighting factor which strongly influences the index value. The objective of this poster is so to compare 8 different DEM's resolutions (12, 24, 48, 72, 96, 204, 504 and 996cm) and 3 different weighting factors (factor C of Wischmeier, Manning's factor and rugosity index) in the Borselli's index calculation. The IC was calculated in a 124ha catchment (Hevillers), in the loess belt, in Belgium. The DEM used is coming from a UAV with a maximum resolution of 12 cm. Permanent covered surfaces are not considered in order to avoid artefact due to the vegetation (2% of the surface). Regarding the DEM pixel size, the IC increases for a given pixel when the pixel size decreases. That confirms some results observed in the Alpine region by Cavalli (2014). The mean difference between 12 cm and 10 m resolution is 35% with higher values up to 100% for higher connectivity zones (flow paths). Another result is the lower impact of connections in the watershed (grass strips…) at lower pixel sizes. This is linked to the small width of some connections which are sometimes comparing to cell size. Furthermore, a great loss of precision is observed from the 500 cm pixel size and upper. That remark is quite intuitive. Finally, some very well disconnected zones appear for the highest resolutions. Regarding the weighting factor, IC values calculated using C factor are lower than with the rugosity index which is only a topographic factor. With very high resolution DEM, it permits to represent the fine topography. For the C factor, the zones up to very well disconnected areas (grass strips, wood…) are well represented with lower index values than downstream

The impact-echo method is based on the use of elastic waves. It was developed in the 1980 for the testing of concrete structures and is currently widespread. Main application areas are the component and coating thickness measurement and detection of delaminations, voids and other defects. Specifically, the method is also used to check the injection faults of clamping channels. Another application is the determination of mechanical material parameters such as the modulus of elasticity. Since the original development of the method has undergone several enhancements. The conversion of a single-point measurement method towards a area component testing, the use by the optimized measurement data acquisition and evaluation enlarged and delivered an important prerequisite for increasing the efficiency. The use of air-coupled sensors not only increases the measurement speed but also provides advantages in rough component surfaces. The imaging analysis in conjunction with signal processing algorithms simplifies the interpretation and allows statistical evaluation. [German] Das Impact-Echo-Verfahren beruht auf der Nutzung elastischer Wellen. Es wurde in den 1980er Jahren fuer die Pruefung von Stahlbetonbauteilen entwickelt und ist derzeit weit verbreitet. Haupteinsatzgebiete sind die Bauteil- und Schichtdickenmessung sowie die Detektion von Delaminationen, Hohl- und anderen Fehlstellen. Insbesondere wird das Verfahren auch zur Pruefung des Verpresszustandes von Spannkanaelen herangezogen. Eine weitere Anwendung ist die Bestimmung mechanischer Materialparameter wie dem Elastizitaetsmodul. Seit der urspruenglichen Entwicklung hat das Verfahren verschiedene Weiterentwicklungen erfahren. Die Ueberfuehrung von einem Einzelpunktmessverfahren hin zu einer flaechigen Bauteilpruefung hat die Einsatzmoeglichkeiten durch die optimierte Messdatenaufnahme und -auswertung vergroessert und eine wichtige Voraussetzung zur Erhoehung der Leistungsfaehigkeit geliefert.

Filme über das Ghetto Litzmannstadt (in Łódź haben bei Weitem noch nicht die gleiche mediale Anerkennung erfahren wie Produktionen über das Warschauer Ghetto; meist wird das Warschauer Ghetto als zentrales Motiv verwendet, wenn in der polnischen Filmkunst das Thema der Juden behandelt  wird. Durch das generelle   Fehlen von Darstellungen der Tragödie um das Ghetto Litzmannstadt in Form von Denkmälern sowohl in der Stadt Łódź als auch in Polen allgemein, wird diese Sachlage in ein anderes Licht gerückt. Das Andenken an das Ghetto Litzmannstadt ist unterrepräsentiert und wird durch jener Art von Gedenken unterdrückt, die die Geschichten der Überlebenden und derjenigen, die Juden das Leben gerettet haben, erzählen, nicht jedoch derer, die ihr Leben verloren haben. Polnische Dokumentarfilme über das Ghetto Litzmannstadt zeichnen sich meist durch gestalterische Schlichtheit und geringe Verbreitung in den Kinos  aus – mit Ausnahme von Likwidacji 08.1944 / Liquidation 08.1944 von Michał Bukojemski und Marcin Miller, dem ersten polnischen Dokumentarfilm in 3D. Wollte man solche Produktionen anhand der besprochenen Thematik klassifizieren, so wären unter den am häufigsten wiederkehrenden Themen folgende zu finden: Das Ghetto, die sog. “Gehsperre”, biografische Filme sowie das Motiv der Rückkehr in das Ghetto nach dem Krieg. Letzteres wird durch die Geschichten tschechischer Überlebender, die nach Łódź zurückkehren, dargestellt, zu finden in Dokumentationen von Borys Lankosz und Pavel Štingl. Bis in die 90er Jahre waren Dokumentarfilme häufig von Erzählungen aus dem Off geprägt, welche das Bild beherrschten. Ab den 1990ern ist der Überlebende selbst als Zeuge und Kommentator in Erscheinung getreten und seine Gegenwart wird mit einer realitätsnahen Darstellungsart aufgezeichnet, die  die Identifikation mit jüdischen Figuren erleichtert. Filmmaterial, das deutsche Teams 1940 im Ghetto aufgenommen haben, taucht in polnischen

Sultan Mahmud II period is known as the period of reforms in Ottoman history. In spite of the important political problems inside and outside that have taken place, important arrangements have been made in the structure of the state in this period. The central organization, army, education and provincial administration have been reorganized. As the tımar administration was abolished in the provincial administration in this period. The change of the provincial system towards the provincial system and the establishment of the mukhtar administration became effective. With the removal of the province organization, mukhtars were assigned instead of the imams who were unable to fulfill their obligatory mandate to increase the immigration to Istanbul. After the establishment of the mukhtar organization in the province first in Kastamonu province. Safranbolu is one of the first residential areas where the mukhtar organization was established. Safranbolu was located within the borders of Kastamonu province during this period. In this study, the establishment of the mukhtar organization in the center of Safranbolu and it’s surroundings the first elected mukhtars were evaluated within the archive documents.

Why does the efficiency of a condensing boiler system increase by 5 percent if the temperature is lowered from 45 to 30 degrees centigrade?

Von Start-ups lernen - Methoden und Entwicklungsprozesse, die Jungunternehmen erfolgreich machen

Science.gov (United States)

Böhme, Eckhart

Die Start-up-Bewegung bringt beständig sog. Disruptoren hervor, die jede Branche betreffen und so gut wie keinen Lebensbereich auslassen. Diese Jungunternehmen, insbesondere aus der Softwarebranche, verfügen zwar nicht über Ressourcen wie etablierte Unternehmen, sie sind jedoch agil, "hungrig", können frei von "Ballast" agieren und treiben die Digitalisierung aller Branchen voran. Aber auch Start-ups können nicht einfach ungetestete Ideen in erfolgreiche Produkte oder Dienstleistungen umwandeln und ihren Erfolg dem Zufall überlassen. Erfolgreiche Jungunternehmen folgen vielmehr einem strukturierten Prozess, um marktgetestete Nutzenversprechen und Geschäftsmodelle zu entwickeln. Zunehmend adaptieren etablierte Unternehmen innovative Entwicklungsprozesse und Methoden. Die Fragestellung für Energieversorgungsunternehmen (EVUs) lautet, welche Methoden, Werkzeuge und Entwicklungsprozesse, die heute bei vielen Start-ups eingesetzt werden, sie aufgreifen können, um das Unternehmen gegenüber Disruptoren robust zu machen?

The EVE plus RHESSI DEM for Solar Flares, and Implications for Residual Non-Thermal X-Ray Emission

Science.gov (United States)

McTiernan, James; Caspi, Amir; Warren, Harry

2016-05-01

Solar flare spectra are typically dominated by thermal emission in the soft X-ray energy range. The low energy extent of non-thermal emission can only be loosely quantified using currently available X-ray data. To address this issue, we combine observations from the EUV Variability Experiment (EVE) on-board the Solar Dynamics Observatory (SDO) with X-ray data from the Reuven Ramaty High Energy Spectroscopic Imager (RHESSI) to calculate the Differential Emission Measure (DEM) for solar flares. This improvement over the isothermal approximation helps to resolve the ambiguity in the range where the thermal and non-thermal components may have similar photon fluxes. This "crossover" range can extend up to 30 keV.Previous work (Caspi et.al. 2014ApJ...788L..31C) concentrated on obtaining DEM models that fit both instruments' observations well. For this current project we are interested in breaks and cutoffs in the "residual" non-thermal spectrum; i.e., the RHESSI spectrum that is left over after the DEM has accounted for the bulk of the soft X-ray emission. As in our earlier work, thermal emission is modeled using a DEM that is parametrized as multiple gaussians in temperature. Non-thermal emission is modeled as a photon spectrum obtained using a thin-target emission model ('thin2' from the SolarSoft Xray IDL package). Spectra for both instruments are fit simultaneously in a self-consistent manner.For this study, we have examined the DEM and non-thermal resuidual emission for a sample of relatively large (GOES M class and above) solar flares observed from 2011 to 2014. The results for the DEM and non-thermal parameters found using the combined EVE-RHESSI data are compared with those found using only RHESSI data.

Effect of aging in HDPE blended with DEM in decalin

International Nuclear Information System (INIS)

Silva, P.; Albano, C.; Karam, A.; Vargas, M.G.; Perera, R.

2006-01-01

Electron paramagnetic resonance (EPR) was used to study the effect of aging on irradiated samples of high-density polyethylene (HDPE) blended with diethyl maleate (DEM) in different proportions. Initially, we synthesize the HDPE using bis-(cyclopentadienyl) zirconium dichloride and P-MAO. The functionalization of the synthesized HDPE was carried out in a 10% weight/vol of polyethylene in decalin solution using different percentages of diethyl maleate (5, 10, 15 and 30% in weight). The samples were irradiated at 5, 15 and 30 kGy. An exponential decay in the total free radicals concentration was observed in the pure HDPE sample at the 15 and 30 kGy irradiation doses, as it was expected. For the 15 and 30 kGy irradiation doses the HDPE blended with 15 and 30% of DEM in decalin shows an increase in the total free radical concentrations as the storage time is increased. This behavior has been interpreted in terms of trapped free radicals. (Author)

Parallel Resolved Open Source CFD-DEM: Method, Validation and Application

Full Text Available In the following paper the authors present a fully parallelized Open Source method for calculating the interaction of immersed bodies and surrounding fluid. A combination of computational fluid dynamics (CFD and a discrete element method (DEM accounts for the physics of both the fluid and the particles. The objects considered are relatively big compared to the cells of the fluid mesh, i.e. they cover several cells each. Thus this fictitious domain method (FDM is called resolved. The implementation is realized within the Open Source framework CFDEMcOupling (www.cfdem.com, which provides an interface between OpenFOAM® based CFD-solvers and the DEM software LIGGGHTS (www.liggghts.com. While both LIGGGHTS and OpenFOAM® were already parallelized, only a recent improvement of the algorithm permits the fully parallel computation of resolved problems. Alongside with a detailed description of the method, its implementation and recent improvements, a number of application and validation examples is presented in the scope of this paper.

Er begann damit, dass er an der Ordendsschule am Kloster des hl. Bernhardins aus Siena jeden Tag drei Stunden lang die "Lehrmeinungen" von Petrus Lombardus aus der Sicht des Duns Scotus kommentierte. Im gleichen Jahr nahm er Darüber hinaus die Vorlesungstätigkeit an der Theologischen Fakultät der Krakauer Universität zu Problemen des zweiten Buches der "Lehrmeinungen" auf. Ausser theologischen Vorlesungen hielt er auch Vortäge Uber philosophische Probleme. Parallel zu seiner Lahrtätigkeit bereitete er den Druck seines mehrbändigen Kommentars zu den "Lehrmeinungen" und zu den hermetischen Schriften unter dem Titel: "Pymander Mercurii Trismegisti" vor, die in Geiste einer versöhnlichen Irenik gehalten waren.

GPU based contouring method on grid DEM data

Science.gov (United States)

Tan, Liheng; Wan, Gang; Li, Feng; Chen, Xiaohui; Du, Wenlong

2017-08-01

This paper presents a novel method to generate contour lines from grid DEM data based on the programmable GPU pipeline. The previous contouring approaches often use CPU to construct a finite element mesh from the raw DEM data, and then extract contour segments from the elements. They also need a tracing or sorting strategy to generate the final continuous contours. These approaches can be heavily CPU-costing and time-consuming. Meanwhile the generated contours would be unsmooth if the raw data is sparsely distributed. Unlike the CPU approaches, we employ the GPU's vertex shader to generate a triangular mesh with arbitrary user-defined density, in which the height of each vertex is calculated through a third-order Cardinal spline function. Then in the same frame, segments are extracted from the triangles by the geometry shader, and translated to the CPU-side with an internal order in the GPU's transform feedback stage. Finally we propose a "Grid Sorting" algorithm to achieve the continuous contour lines by travelling the segments only once. Our method makes use of multiple stages of GPU pipeline for computation, which can generate smooth contour lines, and is significantly faster than the previous CPU approaches. The algorithm can be easily implemented with OpenGL 3.3 API or higher on consumer-level PCs.

This is the final report of the Technology Project 'NO{sub x} reduction by means of homogenisation of mixtures inside combustion chambers', which is part of the Engine 3E 2010 programme of the BMBF, which was to promote research in aircraft engineering. In this project, technologies were developed to achieve a 60% reduction of NO{sub x} emissions as compared to ICAO '95 in an annular combustion chamber in realistic operating conditions where the emissions of substances oher than NO{sub x} were to be of the same level as the emissions of modern jet drives. Further, the design of the new combustion chamber was to be conventional in order to retain the possibility of converting existing propulsion systems to the new technology.

FEM × DEM: a new efficient multi-scale approach for geotechnical problems with strain localization

Directory of Open Access Journals (Sweden)

Nguyen Trung Kien

2017-01-01

Full Text Available The paper presents a multi-scale modeling of Boundary Value Problem (BVP approach involving cohesive-frictional granular materials in the FEM × DEM multi-scale framework. On the DEM side, a 3D model is defined based on the interactions of spherical particles. This DEM model is built through a numerical homogenization process applied to a Volume Element (VE. It is then paired with a Finite Element code. Using this numerical tool that combines two scales within the same framework, we conducted simulations of biaxial and pressuremeter tests on a cohesive-frictional granular medium. In these cases, it is known that strain localization does occur at the macroscopic level, but since FEMs suffer from severe mesh dependency as soon as shear band starts to develop, the second gradient regularization technique has been used. As a consequence, the objectivity of the computation with respect to mesh dependency is restored.

Parallelizing flow-accumulation calculations on graphics processing units—From iterative DEM preprocessing algorithm to recursive multiple-flow-direction algorithm

Science.gov (United States)

Qin, Cheng-Zhi; Zhan, Lijun

2012-06-01

As one of the important tasks in digital terrain analysis, the calculation of flow accumulations from gridded digital elevation models (DEMs) usually involves two steps in a real application: (1) using an iterative DEM preprocessing algorithm to remove the depressions and flat areas commonly contained in real DEMs, and (2) using a recursive flow-direction algorithm to calculate the flow accumulation for every cell in the DEM. Because both algorithms are computationally intensive, quick calculation of the flow accumulations from a DEM (especially for a large area) presents a practical challenge to personal computer (PC) users. In recent years, rapid increases in hardware capacity of the graphics processing units (GPUs) provided in modern PCs have made it possible to meet this challenge in a PC environment. Parallel computing on GPUs using a compute-unified-device-architecture (CUDA) programming model has been explored to speed up the execution of the single-flow-direction algorithm (SFD). However, the parallel implementation on a GPU of the multiple-flow-direction (MFD) algorithm, which generally performs better than the SFD algorithm, has not been reported. Moreover, GPU-based parallelization of the DEM preprocessing step in the flow-accumulation calculations has not been addressed. This paper proposes a parallel approach to calculate flow accumulations (including both iterative DEM preprocessing and a recursive MFD algorithm) on a CUDA-compatible GPU. For the parallelization of an MFD algorithm (MFD-md), two different parallelization strategies using a GPU are explored. The first parallelization strategy, which has been used in the existing parallel SFD algorithm on GPU, has the problem of computing redundancy. Therefore, we designed a parallelization strategy based on graph theory. The application results show that the proposed parallel approach to calculate flow accumulations on a GPU performs much faster than either sequential algorithms or other parallel GPU

Full Text Available Satellite remote sensing provides a powerful instrument for mapping and monitoring traces of historical settlements and infrastructure, not only in distant areas and crisis regions. It helps archaeologists to embed their findings from field surveys into the broader context of the landscape. With the start of the TanDEM-X mission, spatially explicit 3D-information is available to researchers at an unprecedented resolution worldwide. We examined different experimental TanDEM-X digital elevation models (DEM that were processed from two different imaging modes (Stripmap/High Resolution Spotlight using the operational alternating bistatic acquisition mode. The quality and accuracy of the experimental DEM products was compared to other available DEM products and a high precision archaeological field survey. The results indicate the potential of TanDEM-X Stripmap (SM data for mapping surface elements at regional scale. For the alluvial plain of Cilicia, a suspected palaeochannel could be reconstructed. At the local scale, DEM products from TanDEM-X High Resolution Spotlight (HS mode were processed at 2 m spatial resolution using a merge of two monostatic/bistatic interferograms. The absolute and relative vertical accuracy of the outcome meet the specification of high resolution elevation data (HRE standards from the National System for Geospatial Intelligence (NSG at the HRE20 level.

Full Text Available Einleitung: Da es nach Standardtherapie eines lokalisierten oder lokal fortgeschrittenen Prostatakarzinoms häufig zu einem Fortschreiten der Erkrankung kommt, erscheint in Anlehnung an die Antiöstrogentherapie beim Mammakarzinom eine frühzeitige antiandrogene Therapie sinnvoll, um Rezidivrate und Mortalität zu senken. Patienten & Methoden: In einer multizentrischen prospektiv randomisierten placebokontrollierten Doppelblindstudie wurden weltweit 8113 Patienten mit nicht metastasiertem Prostatakarzinom nach Standardtherapie (radikale Prostatektomie, Radiotherapie oder Watchful Waiting mit dem nicht steroidalen Antiandrogen Bicalutamid 150 mg oder Placebo einmal täglich behandelt. Eine Krankheitsprogression wurde durch eine Knochenszintigraphie, CT, MRI, Ultraschall oder durch Biopsie bestätigt, der Tod eines Patienten wurde unabhängig von der jeweiligen Ursache ebenfalls als Progression gewertet. Ergebnisse: Nach einer medianen Beobachtungsdauer von 3 Jahren zeigte sich in der Bicalutamid-Gruppe ein um 42 % signifikant reduziertes Progressionsrisiko im Vergleich zu Placebo. Zu diesem Zeitpunkt fand sich bei 11 % aller Patienten ein Krankheitsprogress. Diese positive Wirkung wurde unabhängig vom zu Grunde liegenden Tumorstadium und der vorhergehenden Therapie beobachtet. Das Auftreten von Knochenmetastasen war in der Bicalutamid-Gruppe um 33 % vermindert, das Risiko einer PSA-Progression um 59 %. Die häufigsten Nebenwirkungen dieser antiandrogenen Therapie waren das Auftreten einer Gynäkomastie und/oder von Brustschmerzen bei insgesamt 86 % der Patienten. Aufgrund der kurzen Beobachtungszeit sind die Überlebensdaten noch nicht aussagekräftig, da erst 6 % aller Patienten verstorben sind, am Prostatakarzinom selbst sogar erst knapp 2 %. Schlußfolgerung: Bicalutamid 150 mg einmal täglich als Soforttherapie, entweder als Mono- oder als adjuvante Therapie zur Standardtherapie mit kurativer Intention, vermindert das Progressionsrisiko bei

Large-baseline InSAR for precise topographic mapping: a framework for TanDEM-X large-baseline data

Directory of Open Access Journals (Sweden)

2017-09-01

Full Text Available The global Digital Elevation Model (DEM resulting from the TanDEM-X mission provides information about the world topography with outstanding precision. In fact, performance analysis carried out with the already available data have shown that the global product is well within the requirements of 10 m absolute vertical accuracy and 2 m relative vertical accuracy for flat to moderate terrain. The mission's science phase took place from October 2014 to December 2015. During this phase, bistatic acquisitions with across-track separation between the two satellites up to 3.6 km at the equator were commanded. Since the relative vertical accuracy of InSAR derived elevation models is, in principle, inversely proportional to the system baseline, the TanDEM-X science phase opened the doors for the generation of elevation models with improved quality with respect to the standard product. However, the interferometric processing of the large-baseline data is troublesome due to the increased volume decorrelation and very high frequency of the phase variations. Hence, in order to fully profit from the increased baseline, sophisticated algorithms for the interferometric processing, and, in particular, for the phase unwrapping have to be considered. This paper proposes a novel dual-baseline region-growing framework for the phase unwrapping of the large-baseline interferograms. Results from two experiments with data from the TanDEM-X science phase are discussed, corroborating the expected increased level of detail of the large-baseline DEMs.

Full Text Available This research aims to explore the acceptance of Moodle as a teaching and learning tool by the faculty of the Department of Information Studies (IS at Sultan Qaboos University (SQU in the Sultanate of Oman. The researchers employed the Unified Theory of Acceptance and Use of Technology (UTAUT to examine the effects of performance expectancy, effort expectancy, social influence and facilitating conditions on the behav-ioural intention of SQU faculty members to employ Moodle in their instruction. Data were collected by the interview method. Results showed the emergence of two faculty groups: one uses Moodle and one does not use Moodle. In group that uses Moodle, performance expectancy, effort expectancy, social influence, facilitating conditions and behavioural intention are positively related, thereby influencing the faculty members’use behavior. In addition to the aforementioned UTAUT constructs, four additional factors affect Moodle’s adoption. These moderators are gender, age, experience and the voluntariness of use, amongst which gender exhibits the least influence on Moodle adoption. That is, male and female faculty generally both use the learning platform. Although some members of the group that does not use Moodle exhibit optimistic performance expectancy for technology, the overall perception in this regard for Moodle is negative. The other UTAUT constructs exert no influence on this group’s adoption of the learning platform.

For reasons of environmental protection and in order to maintain a constant pressure level, hydrogeothermal water must be re-injected into the reservoir after use. However, human interception in the natural fluid/rock system will change the thermodynamic parameters and also the pH and redox potential. This may cause interactions between bedrock, underground water, and the re-injected fluid and have negatives effects on injectivity. Research is going on in this field on the basis of the experience gained in geothermal heating stations in north eastern Germany. (orig.) [Deutsch] Bei einer energetischen und/oder stofflichen Nutzung hydrogeothermaler Ressourcen muessen die Waesser aus Gruenden des Umweltschutzes und der Druckerhaltung im Speicher wieder in das Reservoir verbracht werden.

Dies kann beim Reinjizieren zu Wechselwirkungen zwischen dem Speichergestein, dem Schichtwasser und dem injizierten Fluid fuehren, was negative Auswirkungen auf die Injektivitaetsentwicklung haben kann.

High-resolution Digital Elevation Models (DEMs) can be used to extract high-accuracy prerequisite drainage networks. A higher resolution represents a larger number of grids. With an increase in the number of grids, the flow direction determination will require substantial computer resources and computing time. Parallel computing is a feasible method with which to resolve this problem. In this paper, we proposed a parallel programming method within the .NET Framework with a C# Compiler in a Windows environment. The basin is divided into sub-basins, and subsequently the different sub-basins operate on multiple threads concurrently to calculate flow directions. The method was applied to calculate the flow direction of the Yellow River basin from 3 arc-second resolution SRTM DEM. Drainage networks were extracted and compared with HydroSHEDS river network to assess their accuracy. The results demonstrate that this method can calculate the flow direction from high-resolution DEMs efficiently and extract high-precision continuous drainage networks.

2015-01-01

The DISAMATIC casting process production of sand moulds is simulated with DEM (discrete element method). The main purpose is to simulate the dynamics of the flow of green sand, during the production of the sand mould with DEM. The sand shot is simulated, which is the first stage of the DISAMATIC casting process. Depending on the actual casting geometry the mould can be geometrically quite complex involving e.g. shadowing effects and this is directly reflected in the sand flow during the moulding process. In the present work a mould chamber with “ribs” at the walls is chosen as a baseline geometry to emulate some of these important conditions found in the real moulding process. The sand flow is simulated with the DEM and compared with corresponding video footages from the interior of the chamber during the moulding process. The effect of the rolling resistance and the static friction coefficient is analysed and discussed in relation to the experimental findings. (paper)

Satellite image such as Landsat 5 TM scene provides excellent representation of Earth and synoptic view of large geographic areas in different band combination. Landsat TM images allow automatic and semi-automatic classification of land cover, nevertheless the software frequently may some difficulties in distinguishing between similar radiometric surfaces. In this case, the use of Digital Elevation Model (DEM) can be an important tool to identify different surface covers. In this study, several False Color Composite (FCC) of Landsat 5 TM Image, DEM and the respective draped image of them, were used to delineate lithological boundaries and tectonic features of regional significance of the Paven Volcanic Field (PVF). PFV is a Quaternary fissural structure belonging to the black-arc extensional areas of the Andes in the Mendoza Province (Argentina) characterized by many composite basaltic lava flow fields. The necessity to identify different lava flows with the same composition, and then with same spectral features, allows to highlight the improvement of synergic use of TM images and shaded DEM in the visual interpretation. Information obtained from Satellite data and DEM have been compared with previous geological maps and transferred into a topographical base map. Based on these data a new lithological map at 1:100.000 scale has been presented [it

DEM Extraction from ASTER stereo pairs and three-dimensional registration by reference to ICESat laser altimetry data are carried out in upstream area of Lambert Glacier, East Antarctica. Since the study area is located in inland of East Antarctica where few textures exist, registration between DEM and ICESat data is performed. Firstly, the ASTER DEM generation is based on rational function model (RFM) and the procedure includes: a) rational polynomial coefficient (RPC) computation from ASTER metadata, b) L1A image product de-noise and destriping, c) local histogram equalization and matching, d) artificial collection of tie points and bundle adjustment, and e) coarse-to-fine hierarchical matching of five levels and grid matching. The matching results are filtered semi-automatically. Hereafter, DEM is interpolated using spline method with ground points converted from matching points. Secondly, the generated ASTER DEM is registered to ICESat data in three-dimensional space after Least-squares rigid transformation using singular value decomposition (SVD). The process is stated as: a) correspondence selection of terrain feature points from ICESat and DEM profiles, b) rigid transformation of generated ASTER DEM using selected feature correspondences based on least squares technique. The registration shows a good result that the elevation difference between DEM and ICESat data is low with a mean value less than 2 meters and the standard deviation around 7 meters. This DEM is generated and specially registered in Antarctic typical region without obvious ground rock control points and serves as true terrain input for further radar altimetry simulation.

Dissipation consistent fabric tensor definition from DEM to continuum for granular media

Science.gov (United States)

Li, X. S.; Dafalias, Y. F.

2015-05-01

In elastoplastic soil models aimed at capturing the impact of fabric anisotropy, a necessary ingredient is a measure of anisotropic fabric in the form of an evolving tensor. While it is possible to formulate such a fabric tensor based on indirect phenomenological observations at the continuum level, it is more effective and insightful to have the tensor defined first based on direct particle level microstructural observations and subsequently deduce a corresponding continuum definition. A practical means able to provide such observations, at least in the context of fabric evolution mechanisms, is the discrete element method (DEM). Some DEM defined fabric tensors such as the one based on the statistics of interparticle contact normals have already gained widespread acceptance as a quantitative measure of fabric anisotropy among researchers of granular material behavior. On the other hand, a fabric tensor in continuum elastoplastic modeling has been treated as a tensor-valued internal variable whose evolution must be properly linked to physical dissipation. Accordingly, the adaptation of a DEM fabric tensor definition to a continuum constitutive modeling theory must be thermodynamically consistent in regards to dissipation mechanisms. The present paper addresses this issue in detail, brings up possible pitfalls if such consistency is violated and proposes remedies and guidelines for such adaptation within a recently developed Anisotropic Critical State Theory (ACST) for granular materials.

Forced by the deregulation of the energy market and the big drop of electricity prices E.ON Kraftwerke was completely reorganised. Small, flexible units that are focussed on their key tasks were formed. Costs for electricity generation in our plants were reduced. Power plants that are currently not economically efficient are temporarily shut down. Power plants that are permanently not economically efficient are totally shut down. We have now reached a point at which energy prices slowly start to rise again. With our new plant management organization we have a lasting effect on further successfully operating power plants and a positive development of our company. Looking into the future does not create fear about what to do but positive believe that we will soon start new projects. This is the fundament for a stable, successful power plant company. (orig.) [German] Unter dem erheblichen Kostendruck, dem alle Energieversorger derzeit ausgesetzt sind, wurde die Aufbauorganisation von E.ON Energie grundlegend veraendert.

Die Auslastung vorhandener wirtschaftlicher Bloecke ist durch die Konservierung von derzeit nicht wirtschaftlichen bzw. durch die Stillegung langfristig nicht wirtschaftlicher Anlagen erheblich verbessert worden. Nachhaltig wurde damit eine Betriebsfuehrungsstrategie entwickelt, die den Bestand und eine positive Entwicklung der Kraftwerksgesellschaft sichert. (orig.)

High-resolution DEMs for High-mountain Asia: A systematic, region-wide assessment of geodetic glacier mass balance and dynamics

Shean, D. E.; Arendt, A. A.; Osmanoglu, B.; Montesano, P.

2017-12-01

High Mountain Asia (HMA) constitutes the largest glacierized region outside of the Earth's polar regions. Although available observations are limited, long-term records indicate sustained regional glacier mass loss since 1850, with increased loss in recent decades. Recent satellite data (e.g., GRACE, ICESat-1) show spatially variable glacier mass balance, with significant mass loss in the Himalaya and Hindu Kush and slight mass gain in the Karakoram. We generated 4000 high-resolution digital elevation models (DEMs) from sub-meter commercial stereo imagery (DigitalGlobe WorldView/GeoEye) acquired over glaciers in High-mountain Asia from 2002-present (mostly 2013-present). We produced a regional 8-m DEM mosaic for 2015 and estimated 15-year geodetic mass balance for 40000 glaciers larger than 0.1 km2. We are combining with other regional DEM sources to systematically document the spatiotemporal evolution of glacier mass balance for the entire HMA region. We also generated monthly to interannual DEM and velocity time series for high-priority sites distributed across the region, with >15-20 DEMs available for some locations from 2010-present. These records document glacier dynamics, seasonal snow accumulation/redistribution, and processes that affect glacier mass balance (e.g., ice-cliff retreat, debris cover evolution). These efforts will provide basin-scale assessments of snow/ice melt runoff contributions for model cal/val and downstream water resources applications. We will continue processing all archived and newly available commercial stereo imagery for HMA, and will release all DEMs through the HiMAT DAAC.

This CFD study with DEM was done as a part of the Federal Highway Administration’s (FHWA’s) effort to improve scour design procedures. The Computational Fluid Dynamics-Discrete Element Method (CFD-DEM) model, available in CD-Adapco’s StarCCM+ software, was used to simulate multiphase systems, mainly those which combine fluids and solids. In this method the motion of discrete solids is accounted for by DEM, which applies Newton's laws of motion to every particle. The flow of the fluid is determined by the local averaged Navier–Stokes equations that can be solved using the traditional CFD approach. The interactions between the fluid phase and solids phase are modeled by use of Newton's third law. The inter-particle contact forces are included in the equations of motion. Soft-particle formulation is used, which allows particles to overlap. In this study DEM was used to model separate sediment grains and spherical particles laying on the bed with the aim to analyze their movement due to flow conditions. Critical shear stress causing the incipient movement of the sediment was established and compared to the available experimental data. An example of scour around a cylindrical pier is considered. Various depths of the scoured bed and flow conditions were taken into account to gain a better understanding of the erosion forces existing around bridge foundations. The decay of these forces with increasing scour depth was quantified with a ‘decay function’, which shows that particles become increasingly less likely to be set in motion by flow forces as a scour hole increases in depth. Computational and experimental examples of the scoured bed around a cylindrical pier are presented.

Digital Elevation Models (DEMs) are used in many applications in the context of earth sciences such as in topographic mapping, environmental modeling, rainfall-runoff studies, landslide hazard zonation, seismic source modeling, etc. During the last years multitude of scientific applications of Synthetic Aperture Radar Interferometry (InSAR) techniques have evolved. It has been shown that InSAR is an established technique of generating high quality DEMs from space borne and airborne data, and that it has advantages over other methods for the generation of large area DEM. However, the processing of InSAR data is still a challenging task. This paper describes InSAR operational steps and processing chain for DEM generation from Single Look Complex (SLC) SAR data and compare a satellite SAR estimate of surface elevation with a digital elevation model (DEM) from Topography map. The operational steps are performed in three major stages: Data Search, Data Processing, and product Validation. The Data processing stage is further divided into five steps of Data Pre-Processing, Co-registration, Interferogram generation, Phase unwrapping, and Geocoding. The Data processing steps have been tested with ERS 1/2 data using Delft Object-oriented Interferometric (DORIS) InSAR processing software. Results of the outcome of the application of the described processing steps to real data set are presented.

This work deals with numerical simulation of powder caking process caused by capillary condensation phenomenon. Caking consists in unwanted agglomeration of powder particles. This process is often irreversible and not easy to predict. To reproduce mechanism involved by caking phenomenon we have used the Discrete Elements Method (DEM). In the present work, we mainly focus on the role of capillary condensation and subsequent liquid bridge formation within a granular medium exposed to fluctuations of ambient relative humidity. Such bridges cause an attractive force between particles, leading to the formation of a cake with intrinsic physicochemical and mechanical properties. By considering a Representative Elementary Volume (REV), the DEM is then performed by means of a MULTICOR-3D software tacking into account the properties of the cake (degree of saturation) in order to establish relationships between the microscopic parameters and the macroscopic behaviour (tensile strength).

The electrochemical oxidation of ethanol in alkaline solution has been studied on Cu-PVC electrode and Ni/Cu-PVC composite electrodes modified by ruthenium nanoparticles. The techniques used were cyclic voltammetry (CV), steady-state potentiostatic method, on line differential electrochemical mass spectrometry (DEMS), and high-performance liquid chromatography (HPLC). The chemical products: acetaldehyde and acetic acid were detected measuring the proper mass charge (m/z) ratios. These products were also confirmed by HPLC. The surface modification of composite electrodes by ruthenium nanoparticles promotes the formation of acetaldehyde. As shown by DEMS, the surface modification shifts the onset potential for oxygen evolution reaction on the Cu-PVC composite electrode towards more anodic values

The electrochemical oxidation of ethanol in alkaline solution has been studied on Cu-PVC electrode and Ni/Cu-PVC composite electrodes modified by ruthenium nanoparticles. The techniques used were cyclic voltammetry (CV), steady-state potentiostatic method, on line differential electrochemical mass spectrometry (DEMS), and high-performance liquid chromatography (HPLC). The chemical products: acetaldehyde and acetic acid were detected measuring the proper mass charge (m/z) ratios. These products were also confirmed by HPLC. The surface modification of composite electrodes by ruthenium nanoparticles promotes the formation of acetaldehyde. As shown by DEMS, the surface modification shifts the onset potential for oxygen evolution reaction on the Cu-PVC composite electrode towards more anodic values.

Die Struktur von schlankem Materialfluss mit Lean Production Kanban und Innovationen

Science.gov (United States)

Scheid, Wolf-Michael

In der Literatur wird Materialfluss überwiegend in Spezialdisziplinen betrachtet, etwa der Steuerungslogik, der Logistiktechnik oder dem Supply Chain Management. Ein charakterisierendes Merkmal des Materialflusses ist jedoch, dass er sich aus vielfältigen Einzelbausteinen zusammensetzt, die alle harmonisch abgestimmt sein müssen. Die maximal erreichbare Effizienz wird nicht durch Höchstleistungen in dem einen oder anderen Spezialthema bestimmt, sondern durch das schwächste Glied im gesamten komplexen Netzwerk. Den Schnittstellen zwischen den betroffenen Fachbereichen in einem Unternehmen kommt hier eine ganz besondere Bedeutung zu: Erst ein harmonischer Einklang ermöglicht hohe Effektivität. Dies setzt umfassendes Verständnis für interdisziplinäre Notwendigkeiten, ein hohes Maß an Abstimmung mit den operativen Prozessen und letztlich einen einvernehmlichen Umgang und den Respekt vor den Problemstellungen des Anderen voraus.

2000-01-01

The BOREAS HYD-8 team focused on describing the scaling behavior of water and carbon flux processes at local and regional scales. These DEMs were produced from digitized contours at a cell resolution of 100 meters. Vector contours of the area were used as input to a software package that interpolates between contours to create a DEM representing the terrain surface. The vector contours had a contour interval of 25 feet. The data cover the BOREAS MSAs of the SSA and NSA and are given in a UTM map projection. Most of the elevation data from which the DEM was produced were collected in the 1970s or 1980s. The data are stored in binary, image format files. The data files are available on a CD-ROM (see document number 20010000884) or from the Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC).

DEM GENERATION FROM HIGH RESOLUTION SATELLITE IMAGES THROUGH A NEW 3D LEAST SQUARES MATCHING ALGORITHM

Directory of Open Access Journals (Sweden)

T. Kim

2012-09-01

Full Text Available Automated generation of digital elevation models (DEMs from high resolution satellite images (HRSIs has been an active research topic for many years. However, stereo matching of HRSIs, in particular based on image-space search, is still difficult due to occlusions and building facades within them. Object-space matching schemes, proposed to overcome these problem, often are very time consuming and critical to the dimensions of voxels. In this paper, we tried a new least square matching (LSM algorithm that works in a 3D object space. The algorithm starts with an initial height value on one location of the object space. From this 3D point, the left and right image points are projected. The true height is calculated by iterative least squares estimation based on the grey level differences between the left and right patches centred on the projected left and right points. We tested the 3D LSM to the Worldview images over 'Terrassa Sud' provided by the ISPRS WG I/4. We also compared the performance of the 3D LSM with the correlation matching based on 2D image space and the correlation matching based on 3D object space. The accuracy of the DEM from each method was analysed against the ground truth. Test results showed that 3D LSM offers more accurate DEMs over the conventional matching algorithms. Results also showed that 3D LSM is sensitive to the accuracy of initial height value to start the estimation. We combined the 3D COM and 3D LSM for accurate and robust DEM generation from HRSIs. The major contribution of this paper is that we proposed and validated that LSM can be applied to object space and that the combination of 3D correlation and 3D LSM can be a good solution for automated DEM generation from HRSIs.

Heutzutage sind bildgebende Verfahren aus medizinischen Untersuchungen nicht mehr wegzudenken. Diverse Methoden - basierend auf dem Einsatz von Ultraschallwellen, Röntgenstrahlung, Magnetfeldern oder Lichtstrahlen - werden dabei spezifisch eingesetzt und liefern umfangreiches Datenmaterial über den Körper und sein Inneres. Anhand von Mikroskopieaufnahmen aus Biopsien können darüber hinaus Daten über die morphologische Eigenschaften von Körpergeweben gewonnen werden. Aus der Analyse all dieser unterschiedlichen Arten von Informationen und unter Konsultation weiterer klinischer Untersuchungen aus diversen medizinischen Disziplinen kann unter Berücksichtigung von Anamnesedaten ein "Gesamtbild“ des Gesundheitszustands eines Patienten erstellt werden. Durch die Flut der erzeugten Bilddaten kommt der Bildverarbeitung im Allgemeinen und der Bildanalyse im Besonderen eine immer wichtigere Rolle zu. Gerade im Bereich der Diagnoseunterstützung, der Therapieplanung und der bildgeführten Chirurgie bilden sie Schlüsseltechnologien, die den Forschritt nicht nur auf diesen Gebieten maßgeblich vorantreiben.

Influence of different DEMs on the quality of the InSAR results: case study over Bankya and Mirovo areas

Science.gov (United States)

Nikolov, Hristo; Atanasova, Mila

2017-10-01

One of the key input parameters in obtaining end products from SAR data is the DEM used during their processing. This holds true especially when persistent scatterers InSAR method should be applied for example to study slow moving landslides or subsidence. Since nowadays most of the raw SAR data are of space borne origin for their correct processing to high precision products for relatively small areas with centimeter accuracy a DEM taking into account the particularities of the local topography is needed. Most of the DEMs used by the SAR processing software such as SRTM or ASTER are obtained by the same type of instrument and present some disagreements with height information acquired by leveling measurements or other geodetic means. This was the motivation for initiating this research - to prove the need of creating and using local DEM in SAR data processing at small scale and to check what the magnitude of the discrepancy between final InSAR products is in both cases where SRTM/ASTER and local DEM has been used. In addition investigated were two scenarios for SAR data processing - one with small baseline between image pairs and one having large baseline image pairs - in order to find out in which case local DEM has bigger impact. In course of this study two reference areas were considered - Bankya village near Sofia (SW region of Bulgaria) and Mirovo salt extraction site (NE region of Bulgaria). The reason those areas were selected lies in the high number of landslides registered and monitored by the competent authorities in the mentioned locations. The significance of the results obtained is witnessed by the fact that both sites we used have been included as reference sites for Bulgaria in the PanGeo EU funded project dealing with delivering information regarding ground instability geohazard as areas prone to subsidence of natural and manmade origin. In the said project largest part of the information has been extracted from Envisat SAR data, but now this

2017-12-01

The disturbances experienced by the soil due to the pile installation and dynamic soil-structure interaction still present major challenges to foundation engineers. These phenomena exhibit complex behaviors, difficult to measure in physical tests and to reproduce in numerical models. Due to the simplified approach used by the discrete element method (DEM) to simulate large deformations and nonlinear stress-dilatancy behavior of granular soils, the DEM consists of an excellent tool to investigate these processes. This study presents a sensitivity analysis of the effects of introducing a single pile using the PFC2D software developed by Itasca Co. The different scales investigated in these simulations include point and shaft resistance, alterations in porosity and stress fields and particles displacement. Several simulations were conducted in order to investigate the effects of different numerical approaches showing indications that the method of installation and particle rotation could influence greatly in the conditions around the numerical pile. Minor effects were also noted due to change in penetration velocity and pile-soil friction. The difference in behavior of a moving and a stationary pile shows good qualitative agreement with previous experimental results indicating the necessity of realizing a force equilibrium process prior to any load-test to be simulated.

Rosenzweig entwickelt in seinem Hauptwerk, der Stern der Erlösung, ausgehend von eminent theologischen Kategorien, sein philosophisches System. Dem "Monolog des Ich" der traditionellen Philosophie setzt Rosenzweig ein "Neues Denken" von existenzialistischem Gepräge entgegen, das die Mündlichkeit und den Dialog mit dem "Anderen" aufwertet und den Verstand ald Werkzeug der Reflexion ersetzt. Dieses Denken weist Korrespondenzen zur Philosophie W. Benjamins auf. Das "Neue Denken" übte einen starken Einfluss auf E. Lévinas aus, sowie auf zahlreiche interessante philosophie und theologische Ansätze nach dem "linguistic turn" und auf die postmoderne jüdische Geistigkeit. Rosenzweigs Philosophie hat andererseits in seiner Übersetzertätigkeit eine wichtige direkte Anwendung gefunden.

In Denkensgeschichte war ein Weg der begründeten Erkenntnis bevorzugt, auf dem wir gerade das aussuchen, was als haltbar im Änderungsprozess überdauert. Auf diesem Weg können wir ein souveränes denkendes Subjekt treffen, das wegen seiner Rationalität ein fester Grund beim Erkennen der Welt geworden ist. Am Anfang des 20. Jahrhunderts hat Martin Heidegger darauf hingewiesen, dass im altäglichen Leben unserer Erkenntnis das Verständnis dessen vorangeht, was wir besorgen. Heidegger hat also einen anderen Weg auserwählt, auf dem er bemerkt, dass für einen Mensch eher als seine Rationalität das Abfinden mit seiner faktischen Existenz charakteristisch ist. Heideggers Dasein ist nicht mehr ein Souverän, sondern eine Existenz, die sich um Seinsverständnis bemüht. Ungefähr ab 1930 finden wir eine Kehre im Heideggers Denken. Er sucht einen neuen Weg, auf dem er eine Ek-sistenz vorstellen will.

Insight From the Statistics of Nothing: Estimating Limits of Change Detection Using Inferred No-Change Areas in DEM Difference Maps and Application to Landslide Hazard Studies

Science.gov (United States)

Haneberg, W. C.

2017-12-01

Remote characterization of new landslides or areas of ongoing movement using differences in high resolution digital elevation models (DEMs) created through time, for example before and after major rains or earthquakes, is an attractive proposition. In the case of large catastrophic landslides, changes may be apparent enough that simple subtraction suffices. In other cases, statistical noise can obscure landslide signatures and place practical limits on detection. In ideal cases on land, GPS surveys of representative areas at the time of DEM creation can quantify the inherent errors. In less-than-ideal terrestrial cases and virtually all submarine cases, it may be impractical or impossible to independently estimate the DEM errors. Examining DEM difference statistics for areas reasonably inferred to have no change, however, can provide insight into the limits of detectability. Data from inferred no-change areas of airborne LiDAR DEM difference maps of the 2014 Oso, Washington landslide and landslide-prone colluvium slopes along the Ohio River valley in northern Kentucky, show that DEM difference maps can have non-zero mean and slope dependent error components consistent with published studies of DEM errors. Statistical thresholds derived from DEM difference error and slope data can help to distinguish between DEM differences that are likely real—and which may indicate landsliding—from those that are likely spurious or irrelevant. This presentation describes and compares two different approaches, one based upon a heuristic assumption about the proportion of the study area likely covered by new landslides and another based upon the amount of change necessary to ensure difference at a specified level of probability.

Improving low-relief coastal LiDAR DEMs with hydro-conditioning of fine-scale and artificial drainages

Directory of Open Access Journals (Sweden)

Thomas Richard Allen

2015-11-01

Full Text Available Improvements in Light Detection and Ranging (LiDAR technology and spatial analysis of high-resolution digital elevation models (DEMs have advanced the accuracy and diversity of applications for coastal hazards and natural resources management. This article presents a concise synthesis of LiDAR analysis for coastal flooding and management applications in low-relief coastal plains and a case study demonstration of a new, efficient drainage mapping algorithm. The impetus for these LiDAR applications follows historic flooding from Hurricane Floyd in 1999, after which the State of North Carolina and the Federal Emergency Management Agency undertook extensive LiDAR data acquisition and technological developments for high-resolution floodplain mapping. An efficient algorithm is outlined for hydro-conditioning bare earth LiDAR DEMs using available US Geological Survey National Hydrography Dataset canal and ditch vectors. The methodology is illustrated in Moyock, North Carolina, for refinement of hydro-conditioning by combines pre-existing bare earth DEMs with spatial analysis of LiDAR point clouds in segmented and buffered ditch and canal networks. The methodology produces improved maps of fine-scale drainage, reduced omission of areal flood inundation, and subwatershed delineations that typify heavily ditched and canalled drainage areas. These preliminary results illustrate the capability of the technique to improve the representation of ditches in DEMs as well as subsequent flow and inundation modeling that could spur further research on low-relief coastal LiDAR applications.

Schlögel, R.; Marchesini, I.; Alvioli, M.; Reichenbach, P.; Rossi, M.; Malet, J.-P.

2018-01-01

We perform landslide susceptibility zonation with slope units using three digital elevation models (DEMs) of varying spatial resolution of the Ubaye Valley (South French Alps). In so doing, we applied a recently developed algorithm automating slope unit delineation, given a number of parameters, in order to optimize simultaneously the partitioning of the terrain and the performance of a logistic regression susceptibility model. The method allowed us to obtain optimal slope units for each available DEM spatial resolution. For each resolution, we studied the susceptibility model performance by analyzing in detail the relevance of the conditioning variables. The analysis is based on landslide morphology data, considering either the whole landslide or only the source area outline as inputs. The procedure allowed us to select the most useful information, in terms of DEM spatial resolution, thematic variables and landslide inventory, in order to obtain the most reliable slope unit-based landslide susceptibility assessment.

Effect of particle breakage on cyclic densification of ballast: A DEM approach

International Nuclear Information System (INIS)

Thakur, P K; Vinod, J S; Indraratna, B

2010-01-01

In this paper, an attempt has been made to investigate the effect of particle breakage on densification behaviour of ballast under cyclic loading using Discrete Element Method (DEM). Numerical simulations using PFC 2D have been carried out on an assembly of angular particles with and without incorporation of particle breakage. Two-dimensional projection of angular ballast particles were simulated using clusters of bonded circular particles. Degradation of the bonds within a cluster was considered to represent particle breakage. Clump logic was used to make the cluster of particles unbreakable. DEM simulation results highlight that the particle breakage has a profound influence on the cyclic densification behaviour of ballast. The deformation behaviour exhibited by the assembly with breakage is in good agreement with the laboratory experiments. In addition, the evolution of particle displacement vectors clearly explains the breakage mechanism and associated deformations during cyclic loading.

2001-12-01

Bagley Ice Valley, in the St. Elias and Chugach Mountains of south-central Alaska, is an integral part of the largest connected glacierized terrain on the North American continent. From the flow divide between Mt. Logan and Mt. St. Elias, Bagley Ice Valley flows west-northwest for some 90 km down a slope of less than 1o, at widths up to 15 km, to a saddle-gap where it turns south-west to become Bering Glacier. During 4-13 September 2000, an airborne survey of Bagley Ice Valley was performed by Intermap Technologies, Inc., using their Star-3i X-band SAR interferometer. The resulting digital elevation model (DEM) covers an area of 3243 km2. The DEM elevations are orthometric heights, in meters above the EGM96 geoid. The horizontal locations of the 10-m postings are with respect to the WGS84 ellipsoid. On 26 August 2000, 9 to 18 days prior to the Intermap Star-3i survey, a small-aircraft laser altimeter profile was acquired along the central flow line for validation. The laser altimeter data consists of elevations above the WGS84 ellipsoid and orthometric heights above GEOID99-Alaska. Assessment of the accuracy of the Intermap Star-3i DEM was made by comparison of both the DEM orthometric heights and elevations above the WGS84 ellipsoid with the laser altimeter data. Comparison of the orthometric heights showed an average difference of 5.4 +/- 1.0 m (DEM surface higher). Comparison of elevations above the WGS84 ellipsoid showed an average difference of -0.77 +/- 0.93 m (DEM surface lower). This indicates that the X-band Star-3i interferometer was penetrating the glacier surface by an expected small amount. The WGS84 comparison is well within the 3 m RMS accuracy quoted for GT-3 DEM products. Snow accumulation may have occurred, however, on Bagley Ice Valley between 26 August and 4-13 September 2000. This will be estimated using a mass balance model and used to correct the altimeter-derived surface heights. The new DEM of Bagley Ice Valley will provide a reference

Ganzheitliche Digitalisierungsansätze im Stadtwerk: Von der Strategie bis zur Umsetzung

Science.gov (United States)

Dudenhausen, Roman; Hahn, Heike

Digitalisierung muss im Stadtwerk dazu führen, Kundenerwartungen, die heutzutage schon vielfach durch digitales Know-how und Erfahrungen geprägt sind, in einzigartiger Weise zu entsprechen - in Form digitaler Kundenkontaktpunkte, automatisierter Prozesse oder plattformbasierter Geschäftsmodelle. Eine große Rolle spielen dabei unternehmensweit nutzbare Informationen, die eine 360-Grad-Sicht auf den Kunden ermöglichen. Nur in dieser Kombination werden sich nachhaltig Wettbewerbsvorteile generieren lassen. Manch ein Kunde wird die Lust, einen Prozess zu Ende zu gehen, schon vor dem Abschluss verlieren, wenn er nicht unmittelbar und ohne die digitale Welt zu verlassen zum Ziel kommt. Eine nur "halb digitale Kundenerfahrung" wird weder zu Neugeschäft noch zur positiven emotionalen Bindung zwischen Kunden und Stadtwerk führen. Nicht zu unterschätzen sind zudem Erwartungen hinsichtlich zukünftiger Geschäftsmodelle, aus denen sich disruptive Bedrohungen für die herkömmlichen Strom- und Gasangebote ergeben werden. Erste innovative Ansätze finden sich bereits im Markt, die erahnen lassen, dass zurzeit viel diskutierte Technologien wie die Blockchain nicht mehr nur hypothetischer Natur sind. Die Auseinandersetzung mit der Digitalisierung erfolgt dabei sinnvollerweise in einem unternehmensweit abgestimmten Rahmen, der eine zielgerichtete und ganzheitliche Vorgehensweise ermöglicht.

Owing to the intensification of treatment processes and the construction of new sewage plants sewage arisings are due to rise considerably. The thermal treatment of sewage sludge which it has not been possible to avoid or utilise is an important and indispensable part of any sewage sludge disposal concept. If equipped with a state-of-the-art flue gas purification process that uses carbonaceous adsorbents (Sorbalit trademark), thermal treatment of sewage sludge can be regarded as an environmentally safe process technique. [Deutsch] Die anfallenden Klaerschlammengen werden durch die Intensivierung der Klaerprozesse und der Bau neuer Klaeranlagen deutlich zunehmen. Die thermische Behandlung nicht vermiedener oder verwerteter Klaerschlaemme stellt einen bedeutenden und unverzichtbaren Teil der Klaerschlamm-Entsorgungskonzepte dar. Bei Installation einer - dem Stand der Technik - entsprechenden Rauchgasreinigung mit dem Einsatz kohlenstoffhaltiger Adsorbentien (Sorbalit {sup trademark}) ist die thermische Behandlung von Klaerschlamm eine umweltsichere Verfahrenstechnik.

Gasification of biomass followed by power generation from the lean product gas can make a significant contribution to power generation without affecting the climate or environment. It is made even more interesting by the high efficiencies and promising pollution ratings that can be achieved. To make full use of this technology, some technical problems still require solving, and some non-technical obstacles need to be removed. (orig./SR) [Deutsch] Zusammenfassend kann festgehalten werden, dass die Biomassevergasung mit anschliessender Verstromung des Schwachgases einen nennenswerten Beitrag zu einer umwelt- und klimavertraeglicheren Energiebereitstellung in Europa leisten kann. Dies gilt insbesondere vor dem Hintergrund der erreichbaren hohen Stromwirkungsgrade und der vielversprechenden Umweltkenngroessen, durch die diese Technik gekennzeichnet ist. Um die Vorteile der Biomassevergasung realisieren zu koennen, muessen jedoch noch verschiedene technische Probleme geloest und nicht technische Hindernisse aus dem Weg geraeumt werden. (orig./SR)

Full Text Available In diesem Beitrag argumentiere ich, dass die Ermöglichung von Vereinbarkeit zwischen Erwerbsarbeit und Familienleben ein Erfordernis der Gerechtigkeit bildet. Eltern besitzen einen Anspruch auf Vereinbarkeit, der auf zwei Interessen gründet: Dem Interesse am Zugang zur Erwerbstätigkeit und dem Interesse an der Pflege der Eltern-Kind-Beziehung, durch die besondere Güter realisiert werden. Eine staatliche Politik der Vereinbarkeit lässt sich auch gegenüber denjenigen Gruppen rechtfertigen, die kein besonderes Interesse daran haben – gegenüber Erwachsenen, die keine Kinder haben, und gegenüber Eltern, die ein ‚Ernährermodell‘ mit einer klaren Aufgabenteilung zwischen den Partnern bevorzugen. Eine entsprechende Politik muss allerdings die Dimension des Geschlechts beachten, um nicht zu einer Verschärfung der geschlechtsspezifischen Arbeitsteilung zu führen.

We collected patient data from June 2010 to February 2012 from the Hospital Information System (HIS. Patients had to be Omani, aged more than 18 years old, and have T2D with active follow-up and at least three visits within one year to be included in the study. Ninety-three percent of the patients (n=622 were on oral hypoglycemic drugs and/or insulin, and 70% were on statins. Patients’ anthropometric data, biochemical investigations, blood pressure, and duration of diabetes were recorded from the HIS.  Results: Using the recommended standards and guidelines of medical care in diabetes (American Diabetes Association and the American National Cholesterol Education Program III NCDP NIII standards, we observed that 22% of the patients achieved a HbA1C goal of 1.0; females >1.3mmol/L. Almost 60% of the patients had urinary microalbumin/creatinine ratio within the normal range.  Conclusions: The clinical outcomes of the care that T2D patients get at SQUH were lower than those reported in Europe and North America. However, it is similar to those reported in other countries in the Arabian Gulf.

Damage due to intense particle-wall contact in industrial applications can cause severe problems in industries such as mineral processing, mining and metallurgy. Studying the flow dynamics and forces on containing walls can provide valuable feedback for equipment design and optimising operations to prolong the equipment lifetime. Therefore, solids flow-wall interaction phenomena, i.e. induced wall stress and particle flow patterns should be well understood. In this work, discrete element method (DEM) is used to study steady state granular flow in a gravity-fed hopper like geometry with blocks attached to an inclined wall. The effects of different geometries, e.g. different wall angles and spacing between blocks are studied by means of a 3D DEM slot model with periodic boundary conditions. The findings of this work include (i) flow analysis in terms of flow patterns and particle velocities, (ii) force distributions within the model geometry, and (iii) wall stress vs. model height diagrams. The model enables easy transfer of the key findings to other industrial applications handling granular materials.

Following an intensive public health eradication program, the focus of schistosomiasis mansoni at Salalah in Southern Oman (the only focus of schistosomiasis in Oman), appeared to have been eradicated in 1994. Since the vector snails for schistosomiasis mansoni (and also for S. haematobium) were widely endemic in fresh water springs at Salalah, and reintroduction of introduction (or introduction in case of S.haematobium), was possible, we undertook a prospective study in 1995 for schistosomiasis in our patients at the Sultan Qaboos University Hospital (SQUH) and to obtain evidence of visits by these patients to Salalah. From May 1995 to May 2000, Omani and expatriate patients presenting at SQUH were evaluated for possible schistosomiasis (residence in an endemic region, suggestive clinical features) by a search for ova in stool, urine, or in tissue biopsies, or when ova were absent, by serodiagnosis. A retrospective survey of schistosomiasis patients diagnosed in SQUH from 1990 to April 1995 was also performed. Ministry of Health (MOH) data on reports of schistosomiasis (a notifiable disease) in Oman from 1991 to 2000 were obtained. Thirty patients with schistosomiasis were identified, 10 retrospectively and 20 in prospective study. Patients were aged 9 to 60 years, and 25 of them (10 Omanis, 14 Egyptians, 1 Sudanese) contracted the infection in Africa, while 5 Omanis became infected in Salalah (3 in 99). Twelve patients had schistosomiasis mansoni, 6 had schistosomiasis. Haematobia, and in the rest, infection by both parasites was confirmed or possible. The most common presentation (23%) was hepatosplenic schistosomiasis with portal hypertension. No patient admitted to contaminating fresh water with excreta in Salalah. MOH data revealed 3 to 14 cases of schistosomiasis were reported annually between 1991 and 2000, and that all schistosomiasis cases reported from 1994 1998 originated from Africa. Schistosomiasis remains an important health problem in Oman. Many

Im Oktober 2013 setzte der Nobelpreis für Peter Higgs und François Englert den vorläufigen Höhepunkt in der verrückten Geschichte um das sogenannte Gottesteilchen, das Higgs-Boson. Schon im Juli des Vorjahres hatten die Physiker weltweit gejubelt: Mehr als fünfzig Jahre nachdem Peter Higgs und andere Wissenschaftler die Existenz des Teilchens theoretisch begründet hatten, war es im gigantischen Teilchenbeschleuniger CERN gefunden worden. Jetzt erzählen Harald Lesch und seine Co-Autoren, warum sich rund um das Higgs-Teilchen so viele skurrile Missverständnisse und mediale Sensationen ranken. Gewohnt kurzweilig und gut verständlich enthüllen sie, wie aus dem verzweifelt gesuchten „gottverdammten Teilchen“ das Gottesteilchen wurde, dass der Urknall nicht simuliert werden kann und dass Schwarze Löcher nicht unbedingt alles verschlingende Monster sind. Dabei wird deutlich, dass die Suche nach den geheimnisvollen Kräften, die das Universum, unsere Erde und letztlich auch uns Menschen zusammenhalten...

Full Text Available BMI-Referenzwerte werden empfohlen zur Diagnose von Untergewicht, Übergewicht und Adipositas. Österreichische BMI-Referenzwerte sind bis dato nicht in ausreichender Qualität verfügbar. Deshalb wurden im Rahmen einer Querschnittsstudie 15.000 Kinder und Jugendliche zwischen 4 und 19 Jahren vermessen und abgewogen. Perzentilenkurven für Knaben und Mädchen wurden mit dem GAMLSS-Modell errechnet. Als Grenzwert für die Einteilung in Untergewicht, Normalgewicht, Übergewicht und Adipositas wurden Perzentilenkurven durch die entsprechenden BMI-Punkte mit 18 Jahren erstellt, welche den WHO-Grenzen von Unter-, Normal- und Übergewicht bzw. Adipositas bei Erwachsenen entsprechen. Unter Anwendung dieser neuen Grenzwerte sind rund 18 % der Knaben und 12 % der Mädchen übergewichtig, weitere 5 % der Knaben und 3 % der Mädchen sind adipös. Übergewicht und Adipositas sind somit bei Kindern und Jugendlichen in Österreich ein nicht zu vernachlässigendes Problem.

The relationship between oculomotor scanning and reading in poor readers of primary school age is not well known. This study was designed to assess this relationship by determining mean Developmental Eye Movement (DEM) test times and reading speeds in a Spanish non-clinical population of children with poor reading skills but without dyslexia. We conducted a cross-sectional study on 81 poor readers (8-11 years of age) in the third to fifth grades recruited from 11 elementary schools in Madrid, Spain. In each subject with best spectacle correction, oculomotor scanning was measured using the DEM test, and reading speed (words per minute) was assessed by a standardized Spanish contextual reading test. Mean horizontal DEM times were higher than normative values for children in the third, fourth and fifth grades, by 20 seconds, 12 seconds, and 3 seconds respectively. Mean reading speeds were 18 words per minute lower than the norm for the third and fourth grades respectively, and 30 words per minute lower than the norm for the fifth grade. Reading speeds were significantly related to horizontal DEM times (r = -0.53, p school children at an early stage.

In 1996 the two large heat storage tanks in Hamburg-Bramfeld (4,750 cubic metres) and Friedrichshafen-Wiggenhausen (12,000 cubic metres) were built out of concrete with an inner stainless steel lining. This was a big step towards economic efficiency. The research project ``Tight sealing of pit water storage tanks made out of pre-stressed concrete`` was launched by the BMBF in order to show that the concrete construction will not only bear loads but also ensure sealing. Building costs for underground hot water storage tanks could then be reduced by at least 25%. The first results of this research project are presented. The paper also contains recommendations for the further development of heat storage tanks built with pre-stressed concrete. (orig.)

Mit dem Bau dieser beiden Grossspeicher konnte ein richtungsweisender Schritt hin zur Wirtschaftlichkeit gemacht werden, wie man es in Studien vor 15 Jahren nicht fuer moeglich hielt. Mit dem BMBF - Forschungsvorhaben `Dichte Heisswasser - Waermespeicher aus Hochleistungsbeton` soll gezeigt werden, dass das Betontragwerk nicht nur Lasten abtragen sondern auch die Funktion der Abdichtung uebernehmen kann.

Studies have demonstrated that the transition experience of new graduate nurses is complex and frequently negative, leading to dissatisfaction with nursing and increased attrition. Existing studies of new graduate nurses' transition experiences tend to be concerned with the experiences of new graduate nurses in the West. To date, no study has been conducted examining the transition experience in any Middle Eastern country where the cultural context surrounding nursing education and practice is different. To explore the experiences of new graduate nurses during their transition period in the Sultanate of Oman. A qualitative case study utilising an embedded single case design was conducted to investigate the transition experience of new nursing graduates from one university in the Sultanate of Oman. Data were collected from the perspective of new graduate nurses and also from the perspective of other key informants who are key organisational actors such as clinical instructors, managers and preceptors. As is characteristic of case study design, this study employed triangulated methods including individual and focus group interviews, observation and documentary analysis. Data collected were thematically analysed using Microsoft Access. This study showed that nursing is not an attractive choice for Omani students to study and pursue as a future career. During the transition period, new graduate nurses experienced reality shock resulting mainly from a theory-practice gap. They found themselves with limited practical experience but a high level of theoretical knowledge that was difficult to utilise in practice. They experienced many competing priorities in their working environment which resulted in task-orientation and compromised patient care. Many new graduate nurses resented their involvement in basic nursing care, which they believed should not be part of their role as degree nurses. Omani new graduate nurses' transition experiences are complex and highly affected

The predominant theme in 2014 this was certainly the reform of the EEG and around it rambling topics on European level. Too much uncertainty with plant operators, investors and companies in German power generation market, has led in addition to the mentioned legislative package the revision of the EU environmental and energy aid guidelines, State aid procedure of the European Commission regarding the German promotion of electricity from renewable Energy and the process in the case of Aaland Vindkraft before the ECJ. The dynamics on the generation side, inter alia through the increased connection of decentralized generation plants, result in an increasing regulation in power generation.

Koenig, Rolf; Rothacher, Markus; Michalak, Grzegorz; Moon, Yongjin

TerraSAR-X, launched on June 15, 2007, and TanDEM-X, to be launched in September 2009, both carry the Tracking, Occultation and Ranging (TOR) category A payload instrument package. The TOR consists of a high-precision dual-frequency GPS receiver, called Integrated GPS Occultation Receiver (IGOR), for precise orbit determination and atmospheric sounding and a Laser retro-reflector (LRR) serving as target for the global Satellite Laser Ranging (SLR) ground station network. The TOR is supplied by the GeoForschungsZentrum Potsdam (GFZ) Germany, and the Center for Space Research (CSR), Austin, Texas. The objective of the German/US collaboration is twofold: provision of atmospheric profiles for use in numerical weather predictions and climate studies from the occultation data and precision SAR data processing based on precise orbits and atmospheric products. For the scientific objectives of the TanDEM- X mission, i.e., bi-static SAR together with TerraSAR-X, the dual-frequency GPS receiver is of vital importance for the millimeter level determination of the baseline or distance between the two spacecrafts. The paper discusses the feasibility of generating millimeter baselines by the example of GRACE, where for validation the distance between the two GRACE satellites is directly available from the micrometer-level intersatellite link measurements. The distance of the GRACE satellites is some 200 km, the distance of the TerraSAR-X/TanDEM-X formation will be some 200 meters. Therefore the proposed approach is then subject to a simulation of the foreseen TerraSAR-X/TanDEM-X formation. The effect of varying space environmental conditions, of possible phase center variations, multi path, and of varying center of mass of the spacecrafts are evaluated and discussed.

The pyrolysis process of the reaction gas in the spouted bed can be simulated by CFD method, then the concentration field and velocity field can be extracted and coupled with the particle movement behavior which can be simulated by DEM. Particle deposition process can be described by the CVD model based on particle position, velocity and neighboring gas concentration. This multiscale coupling method can be implemented in the Fluent@-EDEM@ software with their UDF (User Definition Function) and API (Application Programming Interface). Base on the multiscale coupling concept, the criterion for evaluating FB-CVD process is given. At first, the volume in the coating furnace is divided into two parts (active coating area and non-active coating area) based on simulation results of chemical pyrolysis process. Then the residence time of all particles in the active coating area can be obtained using the CFD-DEM simulation method. The residence time distribution can be used as a criterion for evaluating the gas-solid contact efficiency and operation performance of the coating furnace. At last different coating parameters of the coating furnace are compared based on the proposed criterion. And also, the future research emphasis is discussed. (author)

DREEM is now considered a valid and reliable tool, which is globally accepted for measuring the medical educational environment. The educational environment encountered by students has an impact on satisfaction with the course of study, perceived sense of well-being, aspirations, and academic achievement. In addition to being measurable, the educational environment can also be changed, thus enhancing the quality of medical education and the environment, and the medical education process. The objective of this study was to assess the educational environment of the Universiti Sultan Zainal Abidin (UniSZA undergraduate medical program from the students’ perspective. The study expected to explore UniSZA medical students’ overall perceptions, perceptions of learning, teachers, atmosphere, academic self-perception, and social self-perception using the DREEM questionnaire. Methods: A cross-sectional survey was conducted to study the perceptions of the students toward the educational environment of UniSZA as a new medical school, using the DREEM questionnaire. All medical students of UniSZA from Years I–V enrolled in the Bachelor of Medicine and Bachelor of Surgery programs were the target population (n=270. Therefore, the universal sampling technique was used. The data were analyzed using the SPSS 20 software. This study obtained ethical clearance from the Faculty of Medicine and Health Sciences, UniSZA. Results: A total of 195 out of 270 students responded

Dem nuklearen Patt zwischen Ostblock und westlichem Staatenbündnis ist es nach weitgehend übereinstimmender Auffassung von Politik und Wissenschaft zu danken, dass der "Kalte Krieg" in der zweiten Hälfte des 20. Jahrhunderts nicht zum weltumfassenden Flächenbrand eskalierte. An der raschen Herstellung dieses Patts waren zwei Dresdner Physiker maßgeblich beteiligt, deren einer im Manhattan-Projekt in den USA gearbeitet hatte und später in England der Spionage für die Sowjetunion und des Verrats des Know-how der Atombombe überführt wurde.

Geometrie verstehen: statisch - kinematisch

Dem Allgemeinen steht begrifflich das Besondere gegenüber. In diesem Sinne sind allgemeine Überlegungen zum Verstehen von Mathematik zu ergänzen durch Untersuchungen hinsichtlich des Verstehens der einzelnen mathematischen Disziplinen, insbesondere der Geometrie. Hier haben viele Schülerinnen und Schüler Probleme. Diese rühren hauptsächlich daher, dass eine fertige geometrische Konstruktion in ihrer statischen Präsentation auf Papier nicht mehr die einzelnen Konstruktionsschritte erkennen lässt; zum Nachvollzug müssen sie daher ergänzend in einer Konstruktionsbeschreibung festgehalten werden.
