  6. Investigation of hurricane Ivan using the coupled ocean-atmosphere-wave-sediment transport (COAWST) model (United States)

    Zambon, Joseph B.; He, Ruoying; Warner, John C.


    The coupled ocean–atmosphere–wave–sediment transport (COAWST) model is used to hindcast Hurricane Ivan (2004), an extremely intense tropical cyclone (TC) translating through the Gulf of Mexico. Sensitivity experiments with increasing complexity in ocean–atmosphere–wave coupled exchange processes are performed to assess the impacts of coupling on the predictions of the atmosphere, ocean, and wave environments during the occurrence of a TC. Modest improvement in track but significant improvement in intensity are found when using the fully atmosphere–ocean-wave coupled configuration versus uncoupled (e.g., standalone atmosphere, ocean, or wave) model simulations. Surface wave fields generated in the fully coupled configuration also demonstrates good agreement with in situ buoy measurements. Coupled and uncoupled model-simulated sea surface temperature (SST) fields are compared with both in situ and remote observations. Detailed heat budget analysis reveals that the mixed layer temperature cooling in the deep ocean (on the shelf) is caused primarily by advection (equally by advection and diffusion).

  7. Post-Hurricane Ivan coastal oblique aerial photographs collected from Crawfordville, Florida, to Petit Bois Island, Mississippi, September 17, 2004 (United States)

    Morgan, Karen L.M.; Krohn, M. Dennis; Peterson, Russell D.; Thompson, Philip R.; Subino, Janice A.


    The U.S. Geological Survey (USGS) conducts baseline and storm response photography missions to document and understand the changes in vulnerability of the Nation's coasts to extreme storms. On September 17, 2004, the USGS conducted an oblique aerial photographic survey from Crawfordville, Florida, to Petit Bois Island, Mississippi aboard a Piper Navajo Chieftain (aircraft) at an altitude of 500 feet (ft) and approximately 1,000 ft offshore. This mission was flown to collect post-Hurricane Ivan data for assessing incremental changes in the beach and nearshore area since the last survey in 2001, and the data can be used in the assessment of future coastal change.

  10. Caring for Ivan Ilyich. (United States)

    Charlton, Blake; Verghese, Abraham


    For over a century, Leo Tolstoy's The Death of Ivan Ilych has been one of the most influential examinations of how we come to terms with our own mortality. Of the many who care for Ivan Ilych, only the uneducated peasant, Gerasim, is able to help him find meaning and resolution before death. An excerpt that describes Gerasim's key interaction with Ivan Ilych is provided. Analysis of the text reveals how cultural values may hinder a patient's ability to confront mortality and how unique social barriers inhibit different caretakers' ability to care for a dying patient.

  13. Ivan Zajc's Bulgarian Songs

    Directory of Open Access Journals (Sweden)

    Stefanka Georgieva


    Full Text Available On the basis of newly discovered historiographic documents, this study traces the »biography« of Ivan Zajc’s Bulgarian songs. It specifies some disputed details with regard to the numbering and structure of two vocal cycles; it submits a transcript of a music sheet of the song Robstvo (The Yoke, op. 843a and the original of an unknown composition Majko kleta (Poor Mother on the verses of the Bulgarian poet Ivan Vazov which has not been registered by Hubert Pettan in Zajc’s catalogue of works. This exploration, together with the historiographic focus, highlights the connection of these opuses with the Bulgarian poetry which gained wide popularity through the anthology Bulgarian Songs by August Harambašić. Indeed, some details which Zajc indicated on the title pages of his scores, lead to this assumption. At the same time, the spread of the songs in Bulgaria indicates the connection of the Croatian composer with Bulgarian musicians, choral societies, schools etc., as a result of which in the first decade of the 20th century Zagreb’s Hrvatski glazbeni zavod became an attractive educational centre for many young Bulgarian people. Ivan Zajc’s Bulgarian Songs have not only enriched the artistic repertoire of Bulgarian choral societies. They outline one of the lines of active multicultural transfer between Bulgaria and Croatia on the border between the last decades of the 19th and the beginning of the 20th centuries. The melodies of his marches, creating the spirit of the struggles for national liberation of Bulgarian nation, have become part of the newly created national musical culture and have been often accepted as Bulgarian in their origin.

    Full Text Available The interview to Ivan Fedele – which opens this number of Music / Technology as ‘provoking’ element – expresses the composer’s attitude towards technology – mainly found in computer music –, the use he made within his work, as well as the developments generally considered harbingers of more interesting perspectives for the future. Several passages stress the primacy of the compositional idea on the technological means and the need of the composer to maintain control of the situation without giving up the prerogatives of the medium; indeed, it must be ‘bent’ – if not specifically designed – to the requirements of the compositional idea.

  18. Un poema epico neolatino su Ivan Mazepa

    Giovanna Siedina


    Full Text Available A Neo-Latin Poem on Ivan Mazepa The author publishes for the first time, translates into Italian, and analyzes a Neo-Latin poem devoted to the Ukrainian hetman Ivan Mazepa, which celebrates the conquest of a few Turkish fortresses along the Dnipro (1695. A peculiar feature of this poem is that, on the one side, it is one of the few, or even the only epic poem devoted to the Ukrainian hetman, while on the other it is modeled, at least partly, on Virgil’s Aeneid. The poem, however, also shows some features of the panegyric genre. The author points out the many linguistic-literary and historical reminiscences, especially those of Latin epic authors and Roman history, but also of the panegyric discourse elaborated by the Latin-Polish rhetorical tradition. Through these reminiscences, the author of the poem aspires to insert the history of Ukraine-Hetmanščyna into the European Latinitas by underlining the glorious deeds of its hetman Ivan Mazepa, whose fundamental contribution to the antemurale christianitatis and to Russian history only recently has begun to be assessed in an objective and unprejudiced manner.

    Full Text Available In addition to geological, hydrogeological investigations and groundwater tracing, detailed surveying of the groundwater quality is becoming particularly important for environmental impact monitoring on karst aquifers. Groundwater quality data contain two types of information i.e. the natural chemistry of water and its modifications caused by antropogenic impacts. The method of results presentation as well as the importance of water quality surveying particularly with respect to the indicators showing its natural chemistry, are shown here exemplified by the St. Ivan spring in Istria, Croatia. Natural chemistry of the groundwater is a consequence of hydrogeochemical facies, and it is used here for interpretation of spring generating conditions and the origin of groundwater. Results obtained so far confirm that the extent of recharge area of the spring change in dependence of the hydrological conditions. Hydrogeochemical characteristics of the spring are presented graphically in the form of correlation diagrams showing major groundwater parameters, saturation conditions and trends of particular parameters as a function of time.

  2. Hurricane Katrina Wind Investigation Report

    Energy Technology Data Exchange (ETDEWEB)

    Desjarlais, A. O.


    This investigation of roof damage caused by Hurricane Katrina is a joint effort of the Roofing Industry Committee on Weather Issues, Inc. (RICOWI) and the Oak Ridge National Laboratory/U.S. Department of Energy (ORNL/DOE). The Wind Investigation Program (WIP) was initiated in 1996. Hurricane damage that met the criteria of a major windstorm event did not materialize until Hurricanes Charley and Ivan occurred in August 2004. Hurricane Katrina presented a third opportunity for a wind damage investigation in August 29, 2005. The major objectives of the WIP are as follows: (1) to investigate the field performance of roofing assemblies after major wind events; (2) to factually describe roofing assembly performance and modes of failure; and (3) to formally report results of the investigations and damage modes for substantial wind speeds The goal of the WIP is to perform unbiased, detailed investigations by credible personnel from the roofing industry, the insurance industry, and academia. Data from these investigations will, it is hoped, lead to overall improvement in roofing products, systems, roofing application, and durability and a reduction in losses, which may lead to lower overall costs to the public. This report documents the results of an extensive and well-planned investigative effort. The following program changes were implemented as a result of the lessons learned during the Hurricane Charley and Ivan investigations: (1) A logistics team was deployed to damage areas immediately following landfall; (2) Aerial surveillance--imperative to target wind damage areas--was conducted; (3) Investigation teams were in place within 8 days; (4) Teams collected more detailed data; and (5) Teams took improved photographs and completed more detailed photo logs. Participating associations reviewed the results and lessons learned from the previous investigations and many have taken the following actions: (1) Moved forward with recommendations for new installation procedures

  5. Female hurricanes are deadlier than male hurricanes. (United States)

    Jung, Kiju; Shavitt, Sharon; Viswanathan, Madhu; Hilbe, Joseph M


    Do people judge hurricane risks in the context of gender-based expectations? We use more than six decades of death rates from US hurricanes to show that feminine-named hurricanes cause significantly more deaths than do masculine-named hurricanes. Laboratory experiments indicate that this is because hurricane names lead to gender-based expectations about severity and this, in turn, guides respondents' preparedness to take protective action. This finding indicates an unfortunate and unintended consequence of the gendered naming of hurricanes, with important implications for policymakers, media practitioners, and the general public concerning hurricane communication and preparedness.

  12. "The Death of Ivan Ilyich" and multiple dimensions of illness. (United States)

    Alves, Paulo Cesar


    The short story "The Death of Ivan Ilyich" (1886), Leo Tolstoy (1828-1910) provides key elements for a reflection on the meaning of long-term illness. Based on Tolstoy's short story the present paper analyzes the multiple dimensions of the process of illness. It starts with the argument that illness is not an a priori totality, but a trajectory of associations between the sick person, the doctor, family members, friends and caregivers. Acting, being affected, thinking and feeling all come together in the development of these associations. The analysis of the Ivan Ilyich's illness will consider the following points: (a) illness as otherness and incomprehensibility (growing unfamiliarity with one's body and the stages by which the body is gradually objectified); (b) illness as trajectories in an field of practices that involves the development of skills and the "education of attention"; (c) modes of health care as a set of techniques, objects and discourses that are put together or associated throughout trajectories concerned with the establishment of health. Long-term illness is therefore a mode of immersion of the sick person in networks of relations that come to be a part of her everyday life.

  16. Ivan Karlov’s “Tsaritsyn Anabasis

    Directory of Open Access Journals (Sweden)

    Matvei I. Davydov


    Full Text Available This paper acquaints the historians with a curious incident that took place in Suzdal in 1674. The present case surprisingly resembles a well-known plot twist of Jaroslav Hašek’s novel The Fateful Adventures of the Good Soldier Švejk During the World War – so called “Budějovice anabasis”, the protagonist’s epic grueling trek around Southern Czechia in the search for his regiment, which billeted in Budějovice. But if Švejk, despite all the vicissitudes, finally managed to achieve the ultimate objective successfully, Suzdal resident Ivan Karlov – a troublemaker and drunkard, sentenced to exile by local writ office and driven out from the city under the supervision of two constables to Tsaritsyn – conversely, some time later all of a sudden returned back to Suzdal teamwise with the convoy. The analysis of that episode revealed two facts worth mentioning. First of all, Suzdal writ office had a decentralized organizational structure: voyevoda’s court was located within the city whilst minor clerks worked apart from him at the Intercession of Theotokos convent. And secondly, it should be emphasized that for much of the 17th century not the voyevoda himself but the convent’s external administrator played the leading role in the writ office’s business routine. Expectedly, the functioning of the named governmental institution had been directly and very adversely affected by both those peculiarities, and only the nuns at the Intercession of Theotokos convent gained an advantage from that extraordinary situation. The publication of primary historical sources describing Ivan Karlov’s banishment complements the study.

    Full Text Available The author questions the perception of Ivan Turgenev as a “non- Christian writer” and studies the problem of the prodigal son motif functioning in a series of his novels. In his novels, Turgenev pictured different phases of the archetypal story, originating from the Gospel parable of the prodigal son. In the novel Rudin he depicted the phase of spiritual wanderings of the hero who had lost touch with his native land — Russia. In his next novels (Home of the Gentry, Fathers and Sons and Smoke, after leading his hero in circles and sending him back to his paternal home, Turgenev reconstructs the model of human behavior, represented in the parable, thereby recognizing the immutability of the idea formalized in the Gospel. The motif of the return to Russian land gets its completion in Turgenev's last novel Virgin Soil, in which the author paradoxically connects the Westernist idea with the Gospel imperative. Solomin, the son of a deacon, sent by his wise father out to Europe “to get education”, studies in England, masters the European knowledge and returns back “to his native land” to establish his own business in inland Russia. Thus, a series of Turgenev's novels, in which he portrayed different phases of social life, are interlinked with the motif of the prodigal son, who is represented by novels' main characters.

  2. Examining Hurricane Track Length and Stage Duration Since 1980 (United States)

    Fandrich, K. M.; Pennington, D.


    Each year, tropical systems impact thousands of people worldwide. Current research shows a correlation between the intensity and frequency of hurricanes and the changing climate. However, little is known about other prominent hurricane features. This includes information about hurricane track length (the total distance traveled from tropical depression through a hurricane's final category assignment) and how this distance may have changed with time. Also unknown is the typical duration of a hurricane stage, such as tropical storm to category one, and if the time spent in each stage has changed in recent decades. This research aims to examine changes in hurricane stage duration and track lengths for the 319 storms in NOAA's National Ocean Service Hurricane Reanalysis dataset that reached Category 2 - 5 from 1980 - 2015. Based on evident ocean warming, it is hypothesized that a general increase in track length with time will be detected, thus modern hurricanes are traveling a longer distance than past hurricanes. It is also expected that stage durations are decreasing with time so that hurricanes mature faster than in past decades. For each storm, coordinates are acquired at 4-times daily intervals throughout its duration and track lengths are computed for each 6-hour period. Total track lengths are then computed and storms are analyzed graphically and statistically by category for temporal track length changes. The stage durations of each storm are calculated as the time difference between two consecutive stages. Results indicate that average track lengths for Cat 2 and 3 hurricanes are increasing through time. These findings show that these hurricanes are traveling a longer distance than earlier Cat 2 and 3 hurricanes. In contrast, average track lengths for Cat 4 and 5 hurricanes are decreasing through time, showing less distance traveled than earlier decades. Stage durations for all Cat 2, 4 and 5 storms decrease through the decades but Cat 3 storms show a

  3. Photography travel journal of Belgrade by Ivan Groman a different view of the photographic work of Ivan Groman

    Directory of Open Access Journals (Sweden)

    Radoš Aleksandar


    Full Text Available Little is known about a Russian photographer, Ivan Groman. His photographic work, originating in 1876 in the Principality of Serbia, was used repeatedly for illustrations, but has never been thoroughly analyzed as a historic document. Although his photographs, kept in the Archives of the City of Belgrade, the Museum of the City of Belgrade, and the Military Museum in Belgrade, may not represent his entire photographic opus, a thorough analysis of his work may serve the purpose of seeking for the message, and therefore for the aim of his work and stay in Belgrade. A small number of his photographs of Belgrade, constituting small series (‘stories’ of a relatively small area, clearly lead to the conclusion that I. V. Groman was not just a photographer – documentarist with an unquestionable and subtle artistic sense, but also a perceptive and possibly experienced “documentarist on a military mission”. It does not diminish the significance and value of his photographic work in Belgrade. Quite the opposite. His opus gains the documentary vigor of the travel journal photo-story, which in its expressiveness does not fall short of the travel journals of a more traditional kind.

  4. Hurricanes and coral bleaching linked to changes in coral recruitment in Tobago. (United States)

    Mallela, J; Crabbe, M J C


    Knowledge of coral recruitment patterns helps us understand how reefs react following major disturbances and provides us with an early warning system for predicting future reef health problems. We have reconstructed and interpreted historical and modern-day recruitment patterns, using a combination of growth modelling and in situ recruitment experiments, in order to understand how hurricanes, storms and bleaching events have influenced coral recruitment on the Caribbean coastline of Tobago. Whilst Tobago does not lie within the main hurricane belt results indicate that regional hurricane events negatively impact coral recruitment patterns in the Southern Caribbean. In years following hurricanes, tropical storms and bleaching events, coral recruitment was reduced when compared to normal years (p=0.016). Following Hurricane Ivan in 2004 and the 2005-2006 bleaching event, coral recruitment was markedly limited with only 2% (n=6) of colonies estimated to have recruited during 2006 and 2007. Our experimental results indicate that despite multiple large-scale disturbances corals are still recruiting on Tobago's marginal reef systems, albeit in low numbers.

  7. Hurricane Imaging Radiometer (United States)

    Cecil, Daniel J.; Biswas, Sayak K.; James, Mark W.; Roberts, J. Brent; Jones, W. Linwood; Johnson, James; Farrar, Spencer; Sahawneh, Saleem; Ruf, Christopher S.; Morris, Mary; hide


    The Hurricane Imaging Radiometer (HIRAD) is a synthetic thinned array passive microwave radiometer designed to allow retrieval of surface wind speed in hurricanes, up through category five intensity. The retrieval technology follows the Stepped Frequency Microwave Radiometer (SFMR), which measures surface wind speed in hurricanes along a narrow strip beneath the aircraft. HIRAD maps wind speeds in a swath below the aircraft, about 50-60 km wide when flown in the lower stratosphere. HIRAD has flown in the NASA Genesis and Rapid Intensification Processes (GRIP) experiment in 2010 on a WB-57 aircraft, and on a Global Hawk unmanned aircraft system (UAS) in 2012 and 2013 as part of NASA's Hurricane and Severe Storms Sentinel (HS3) program. The GRIP program included flights over Hurricanes Earl and Karl (2010). The 2012 HS3 deployment did not include any hurricane flights for the UAS carrying HIRAD. The 2013 HS3 flights included one flight over the predecessor to TS Gabrielle, and one flight over Hurricane Ingrid. This presentation will describe the HIRAD instrument, its results from the 2010 and 2013 flights, and potential future developments.

    Directory of Open Access Journals (Sweden)

    Brook Weld Muller


    Full Text Available This essay describes strategic approaches to graphic representation associated with critical environmental engagement and that build from the idea of works of architecture as stitches in the ecological fabric of the city. It focuses on the building up of partial or fragmented graphics in order to describe inclusive, open-ended possibilities for making architecture that marry rich experience and responsive performance. An aphoristic approach to crafting drawings involves complex layering, conscious absence and the embracing of tension. A self-critical attitude toward the generation of imagery characterized by the notion of ‘loose precision’ may lead to more transformative and environmentally responsive architectures.

  19. Comparison and validation of statistical methods for predicting power outage durations in the event of hurricanes. (United States)

    Nateghi, Roshanak; Guikema, Seth D; Quiring, Steven M


    This article compares statistical methods for modeling power outage durations during hurricanes and examines the predictive accuracy of these methods. Being able to make accurate predictions of power outage durations is valuable because the information can be used by utility companies to plan their restoration efforts more efficiently. This information can also help inform customers and public agencies of the expected outage times, enabling better collective response planning, and coordination of restoration efforts for other critical infrastructures that depend on electricity. In the long run, outage duration estimates for future storm scenarios may help utilities and public agencies better allocate risk management resources to balance the disruption from hurricanes with the cost of hardening power systems. We compare the out-of-sample predictive accuracy of five distinct statistical models for estimating power outage duration times caused by Hurricane Ivan in 2004. The methods compared include both regression models (accelerated failure time (AFT) and Cox proportional hazard models (Cox PH)) and data mining techniques (regression trees, Bayesian additive regression trees (BART), and multivariate additive regression splines). We then validate our models against two other hurricanes. Our results indicate that BART yields the best prediction accuracy and that it is possible to predict outage durations with reasonable accuracy. © 2011 Society for Risk Analysis.

  6. Social and psychological resources associated with health status in a representative sample of adults affected by the 2004 Florida hurricanes. (United States)

    Ruggiero, Kenneth J; Amstadter, Ananda B; Acierno, Ron; Kilpatrick, Dean G; Resnick, Heidi S; Tracy, Melissa; Galea, Sandro


    Overall health status after a disaster may be associated with long-term physical morbidity and mortality. Little is known about factors associated with overall health status in the aftermath of disasters. We examined self-rated health in relation to disaster characteristics, social resources, and post-disaster outcomes in a sample of adults who experienced the 2004 Florida hurricanes. We interviewed a representative sample of 1,452 adults aged 18 years and older residing in the 33 Florida counties that were in the direct path of at least one of the 2004 hurricanes (Charley, Frances, Ivan, Jeanne). Overall health status was assessed using a self-rating format known to be predictive of mortality. Poor self-rated health was endorsed by 14.6% of the sample. Final multivariable models showed that poor self-rated health was associated with older age (p hurricane (p = 0.03), low social support (p = 0.03), and depression (p = 0.003) since the hurricane. Self-rated health following the Florida hurricanes was strongly associated with two variables (social support and depression) that potentially can be mitigated through targeted interventions after disasters. Future work should evaluate secondary prevention strategies that can address general health-related concerns in the wake of a disaster.

  10. Design Graphics (United States)


    A mathematician, David R. Hedgley, Jr. developed a computer program that considers whether a line in a graphic model of a three-dimensional object should or should not be visible. Known as the Hidden Line Computer Code, the program automatically removes superfluous lines and displays an object from a specific viewpoint, just as the human eye would see it. An example of how one company uses the program is the experience of Birdair which specializes in production of fabric skylights and stadium covers. The fabric called SHEERFILL is a Teflon coated fiberglass material developed in cooperation with DuPont Company. SHEERFILL glazed structures are either tension structures or air-supported tension structures. Both are formed by patterned fabric sheets supported by a steel or aluminum frame or cable network. Birdair uses the Hidden Line Computer Code, to illustrate a prospective structure to an architect or owner. The program generates a three- dimensional perspective with the hidden lines removed. This program is still used by Birdair and continues to be commercially available to the public.

  16. Biographic Parallels as a Basis for Typological Studying of George Orwell and Ivan Bahrianyi Works

    Directory of Open Access Journals (Sweden)

    Svitlana Korshunova


    Full Text Available This article deals with the problem of biographic parallelism as a basis for typological research. The main task is to find out similarities and differences in the works by George Orwell and Ivan Bahrianyi, all of them being based of the real facts from the writers' lives. The peculiarities of the literary interpretation of the biography of the both authors become the comparative basis for revealing of the common processes in their works. The research sheds the light on the interdependence between authors' motivations and its literary results. It also highlights the problem of genres chosen by the writers and of the dependence of this choice on the biographic facts usage. The article compares the genres of the authors' works from the point of view of their artistic motivation. The subject under study includes such books of the authors as “Burmese Days”, “Keep the Aspidistra Flying” and other by George Orwell, as well as “The Getsyman Garden”, “The Hunters and the Hunted” and others by Ivan Bahrianyi. It deals with the problem of the influence of the writers' biographic facts on their creation of the literary images and characters, as well as on the plots of the stories. The similarities between authors and their characters are revealed and this allows us to say that writers used their own lives as a source of inspiration and artistic motivation for the sake of making their stories credible. The article also raises the question of the nature of the writers' characters with authors' being their possible prototypes. In general, the article studies the parallels of George Orwell and Ivan Bahrianyi lives, trying to prove their compatibility in the typological field while both use their biographies as a creative method.

    Full Text Available Paulo Freire and Ivan Illich are prominent figures in contemporary education, who broke the stable system of education. Paulo Freire suggests to stop bank style education and to promote andragogy education, which views both teacher and students equally. Education should be actualized through facing problems and should be able to omit naïve and magic awareness replaced with critical and transformative awareness. Different from Freire, Illich offers to free the society from formal schools. Education should be run in an open learning network. Technical skills can be taught by drilling. In addition, social transformation will happen only if there are epimethean people that are minority in existence.

  1. Fourth year medical students’ reflective writing on “death of Ivan Ilych: a qualitative study

    Directory of Open Access Journals (Sweden)



    Full Text Available Introduction: Medical students should be familiar with the end of life ethical issues and its considerations. For teaching end of life care to medical students, literature is a source of excellent narratives of patients with experiences of terminally ill condition in their journey through suffering and one of the most favourite bioethics literature readings has been the death of Ivan Ilych by Tolstoy. We used this novel to show medical students end of life events and suffering and asked them to write a reflective essay on it. We aimed to find what students think about terminally ill patients and their journey to death. Methods: In an inductive qualitative content analysis model, 350 essays, collected by homogenous sampling, were analyzed. The fourth year medical students were provided with the Death of Ivan Ilych novel to read. They were asked to write a reflection essay based on the reflective stages defined by Sandars. These essays served as the unit of analysis, each being read several times and a coding model was formed according to main topics. The related concepts in each unit were named as themes and each theme was abstracted to a code and the related codes were compared and developed as categories. Results: Qualitative content analysis of 350 essays of fourth year medical students revealed three major categories in students’ reflection on reading Death of Ivan Ilych as an end of life human body. These included: 1 Emotional experience, 2 Empathy and effective communication, 3 Spirituality and dignity. Analysis of essays showed that this reflection activity may help medical students have a deeper idea of the end of life situation and feelings. Conclusion: This project suggests that literature can be used as an example to introduce new ethical concepts to less experienced medical trainees. The students acquired the concept of the story and reflected the major aspects of the suffering of a human being in their essays. Having used and

    Hurricane Isabel, originally a Category 5 storm, arrived at Jefferson Lab on September 18, 2003 with winds of only 75 mph, creating little direct damage to the infrastructure. However, electric power was lost for four days allowing the superconducting cryomodules to warm up and causing a total loss of the liquid helium. The subsequent recovery of the cryomodules and the impact of the considerable amount of opportunistic preventive maintenance provides important lessons for all accelerator complexes, not only those with superconducting elements. The details of how the recovery process was structured and the resulting improvement in accelerator availability will be discussed in detail

Versatile activity of I. Franko was based on European values, which contributed to high level of spiritual assets inherent to Ukrainian nation. Just as important condition for forming intercultural competencies through professional training of future teachers of foreign languages is a culturologic component with value attitude to national and foreign cultures, so it is brought forward to use creatively of the writer and thinker of genious, Ivan Franko. Franko’s Words are eternal and influence the minds of many people in Europe and the world. Franko was a great strategist of national culture. He set himself the task of making Ukrainian culture more European in general, attaching it to the themes and models of European and world literary process. German literary heritage of Franko should be viewed not only as an important facet of a prominent journalist, writer and scientist, an important means of rapprochement of peoples, mutual enrichment of cultures, but above all as a desire to educate native people, to awaken their national consciousness, to build their own state, and in this case, to form intercultural competence of future teachers, teachers of new generation.

  4. Il Vangelo di Ivan Aleksandăr nella tradizione testuale dei vangeli slavi

    Directory of Open Access Journals (Sweden)

    Alberto Alberti


    Full Text Available Alberto Alberti, Marcello Garzaniti The Ivan Alexander Gospel in the Textual Tradition of the Slavic Gospels In this article, the Authors analyse the Slavic text of the Gospels in the light of the most recent developments in Greek New Testament studies. Particularly useful is the work carried out at the Institut für neutestamentliche Forschung (Münster. On the basis of the identifi cation of a series of ‘Test Passages’ (Teststellen, the Münster volumes offer all the readings of the Greek tradition (except for lectionaries. In this paper, the fi rst 10 chapters of the Gospel of John and the entire text of the synoptic Gospels are analysed from this point of view, comparing the Greek text with a corpus of 12 Slavic manuscripts. The text of the Ivan Alexander Gospel in some instances refl ects the process of harmonization to the Greek ‘Byzantine text’, but in general terms preserves many archaic features, which is quite unusual for a 14th century Gospel. The revision on the basis of Greek manuscripts is also illustrated by readings which are clearly in harmony with particular forms of the Greek text.

  5. A Look Inside Hurricane Alma (United States)


    Hurricane season in the eastern Pacific started off with a whimper late last month as Alma, a Category 2 hurricane, slowly made its way up the coast of Baja California, packing sustained winds of 110 miles per hour and gusts of 135 miles per hour. The above image of the hurricane was acquired on May 29, 2002, and displays the rainfall rates occurring within the storm. Click the image above to see an animated data visualization (3.8 MB) of the interior of Hurricane Alma. The images of the clouds seen at the beginning of the movie were retrieved from the National Oceanic and Atmospheric Association's (NOAA's) Geostationary Orbiting Environmental Satellite (GOES) network. As the movie continues, the clouds are peeled away to reveal an image of rainfall levels in the hurricane. The rainfall data were obtained by the Precipitation Radar aboard NASA's Tropical Rainfall Measuring Mission (TRMM) satellite. The Precipitation Radar bounces radio waves off of clouds to retrieve a reading of the number of large, rain-sized droplets within the clouds. Using these data, scientists can tell how much precipitation is occurring within and beneath a hurricane. In the movie, yellow denotes areas where 0.5 inches of rain is falling per hour, green denotes 1 inch per hour, and red denotes over 2 inches per hour. (Please note that high resolution still images of Hurricane Alma are available in the NASA Visible Earth in TIFF format.)

    This paper reports that reports of damage by Hurricane Andrew escalated last week as operators stepped up inspections of oil and gas installations in the Gulf of Mexico. By midweek, companies operating in the gulf and South Louisiana were beginning to agree that earlier assessments of damage only scratched the surface. Damage reports included scores of lost, toppled, or crippled platforms, pipeline ruptures, and oil slicks. By midweek the U.S. coast Guard had received reports of 79 oil spills. Even platforms capable of resuming production in some instances were begin curtailed because of damaged pipelines. Offshore service companies the another 2-4 weeks could be needed to fully assess Andrew's wrath. Lack of personnel and equipment was slowing damage assessment and repair

    Full Text Available Se questo è un uomo di Primo Levi e Una giornata di Ivan Denisovič di Aleksandr Solženicyn sono due “atti letterari” che hanno contribuito in modo significativo alla conoscenza storica del XX secolo: il primo nell’Occidente dei campi di concentramento nazisti, il secondo nell’Oriente del Gulag. Perché sono così famosi? C’è qualcosa che li accomuna? Questo saggio si propone di analizzare la forza della letteratura come luogo di conoscenza e autocoscienza. Se le opere di Levi e Solženicyn hanno un grande valore come testimonianze, in esse la forza della testimonianza è data dal “gesto letterario” che le ha create, un gesto che produce una conoscenza sintetica in cui gli universali esistono solo nel particolare.

    Full Text Available Roberto Schwarz highlights the exclusion of marginalized classes from discus- sions about Brazilian national identity in “Nacional por subtração” (1987. Incorporating Schwarz’s claim, as well as Engbersen’s five discourses of poverty (1999, this article first contextualizes poverty and its discussion in Brazilian liter- ary history before arguing that Ivan Ângelo’s A Festa (1976 constitutes a type of literature of poverty by subtraction. Ângelo excludes the voice of the poor from the novel, yet he does so precisely in order to call attention to the problematic manner in which literature, journalism, and bureaucratic reports claim to repre- sent the disenfranchised.

  17. The death of Ivan Ilych: A blueprint for intervention at the end of life. (United States)

    Papadimos, Thomas J; Stawicki, Stanislaw Pa


    Medical practice and the field of humanities frequently intersect. It is uncanny how problems presented or described in literature that are several hundred years old still present themselves to us on a regular basis. Often, our answers to these dilemmas are not perfect, but we continue our attempts at providing solutions through an enlightened evolution of our thought and approaches. Leo Tolstoy's novella, The Death of Ivan Ilych, is a classic piece of literature that allows a view of the dying process in an ordinary human being, and presents us with an opportunity to observe, not only the intersection of medicine and humanities, but also that of critical care and palliative medicine. Here Tolstoy, through his keen observation of the human condition at the end of life, allows us an opportunity to view a 19(th) century perspective that has an all too familiar persistence that needs a 21(st) century intervention.

  18. The discipline of architecture and freedom of spirit: Architect Ivan Antić

    Directory of Open Access Journals (Sweden)

    Milašinović-Marić Dijana


    Full Text Available Each epoch has its distinct characters who, by their talent, creativity knowledge and skills, manage to surmount the limiting context and come up as individuals. One among such creators is the architect – Ivan Antić, Member of Academy, who in his design projects and with his distinct architectural credo managed to express the ideals of time in which he was creating. His buildings – masterpieces of the Serbian modern architecture, e.g. Museum of the modern art located at Ušće in Belgrade; Museum for victims of execution in Šumarice sport arenas, public and business edifices, all of them represent unique architectural achievements. Those building forms are both functional and aesthetical, almost as a sublimate in fulfillment of content and construction requirements.

  20. Elements of regional architecture in the works of architect Ivan Antić

    Directory of Open Access Journals (Sweden)

    Milašinović-Marić Dijana


    Full Text Available The body of work of Ivan Antić (Belgrade, 1923-2005, one of the most important Serbian architects who created his works in the period from 1955 to 1990, represents almost a reification of ideals of the times he lived in, both in terms of form and in structural and substantive terms. His work is placed within a rationalistic concept which is essentially experienced as an undisturbed harmony between his personality and the contemporary architectural expression. However, besides such way of interpretation, his architecture also includes examples indicating the thinking about the folk tradition, architectural heritage, the primordial, as well as the archetypal, typical for a region. In the context of the body of work of architect Ivan Antić, this paper will particularly place accent and track such threads of thinking which are, in an obvious or transparent sense, expressed in a series of realized solutions and designs such as the Guard's Home in Dedinje (Belgrade, 1957-1958, Children's Home (Jermenovci, 1956-1957, Museum of the Genocide in Šumarice which he designed together with I. Raspopović (Kragujevac, 1968-1975, 'Politika' Cultural Centre (Krupanj, 1976-1981, '25th May' Sports Center (Belgrade, 1971-1973, or his own house in Lisović near Belgrade. All the abovementioned buildings, as well as numerous other, which belong at the top of Serbian architecture, reflect the spirit of the time in which he created them. They clearly indicate the unbreakable bond which exists in architecture between the inherited, vernacular, contemporary and personal architect's attitude.

  1. Hurricane Data Analysis Tool (United States)

    Liu, Zhong; Ostrenga, Dana; Leptoukh, Gregory


    In order to facilitate Earth science data access, the NASA Goddard Earth Sciences Data Information Services Center (GES DISC) has developed a web prototype, the Hurricane Data Analysis Tool (HDAT; URL:, to allow users to conduct online visualization and analysis of several remote sensing and model datasets for educational activities and studies of tropical cyclones and other weather phenomena. With a web browser and few mouse clicks, users can have a full access to terabytes of data and generate 2-D or time-series plots and animation without downloading any software and data. HDAT includes data from the NASA Tropical Rainfall Measuring Mission (TRMM), the NASA Quick Scatterometer(QuikSCAT) and NECP Reanalysis, and the NCEP/CPC half-hourly, 4-km Global (60 N - 60 S) IR Dataset. The GES DISC archives TRMM data. The daily global rainfall product derived from the 3-hourly multi-satellite precipitation product (3B42 V6) is available in HDAT. The TRMM Microwave Imager (TMI) sea surface temperature from the Remote Sensing Systems is in HDAT as well. The NASA QuikSCAT ocean surface wind and the NCEP Reanalysis provide ocean surface and atmospheric conditions, respectively. The global merged IR product, also known as, the NCEP/CPC half-hourly, 4-km Global (60 N -60 S) IR Dataset, is one of TRMM ancillary datasets. They are globally-merged pixel-resolution IR brightness temperature data (equivalent blackbody temperatures), merged from all available geostationary satellites (GOES-8/10, METEOSAT-7/5 & GMS). The GES DISC has collected over 10 years of the data beginning from February of 2000. This high temporal resolution (every 30 minutes) dataset not only provides additional background information to TRMM and other satellite missions, but also allows observing a wide range of meteorological phenomena from space, such as, hurricanes, typhoons, tropical cyclones, mesoscale convection system, etc. Basic functions include selection of area of

  14. Year-ahead prediction of US landfalling hurricane numbers: intense hurricanes


    Khare, Shree; Jewson, Stephen


    We continue with our program to derive simple practical methods that can be used to predict the number of US landfalling hurricanes a year in advance. We repeat an earlier study, but for a slightly different definition landfalling hurricanes, and for intense hurricanes only. We find that the averaging lengths needed for optimal predictions of numbers of intense hurricanes are longer than those needed for optimal predictions of numbers of hurricanes of all strengths.

  15. Direct and indirect mortality in Florida during the 2004 hurricane season (United States)

    McKinney, Nathan; Houser, Chris; Meyer-Arendt, Klaus


    Previous studies have shown that natural disasters, and hurricanes in particular, have led to more deaths than those usually documented in short post-storm surveys. Such indirect deaths, thought to be related to dietary, stress or pre-existing medical conditions, can exceed the number of direct deaths and may persist for weeks or even months beyond the event itself. In the present study, cumulative sum of deviations plots are used to quantify the number of direct and indirect deaths resulting from Hurricanes Charley, Frances, Ivan and Jeanne that made landfall in Florida in 2004. Results suggest that there was an elevated mortality for up to 2 months following each storm, resulting in a total of 624 direct and indirect deaths attributable to the storm. Trauma-related deaths that can be associated directly with the storm account for only ˜4% of the total storm-related mortality, while indirect mortality accounts for most storm-related deaths. Specifically, a large percentage of the elevated mortality was associated with heart (34%) and cancer-related deaths (19%), while diabetes (5%) and accident-related deaths (9%) account for a smaller but still significant percentage of the elevated mortality. The results further suggest that the elevated mortality was the result of additional deaths that would not have otherwise occurred within that 5 month period, and not simply a clustering of deaths that were inevitable between 1 August and 31 December 2004. The elevated mortality identified in this study is significantly greater than the official count of 31 direct and 113 indirect deaths resulting from the four hurricanes combined. This suggests a need for improved mortality counts and surveillance in order to better evaluate and identify effective prevention policies, and to identify preventable deaths.

  1. Ivan Rančić: A forgotten painter of flowers and landscapes

    Marković Kamenko M.


    Full Text Available Ivan Rančić was born in the Kraljevo village, in eastern Serbia to a family of farmers on 19th, February, 1906. Very little data about him has been preserved, therefore, this paper is an attempt to make a reconstruction of his life and work. He attended primary school in his birth place, lower secondary school he finished in Knjazevac and Military Academy in Belgrade. After completing the National Academy in 1934, he was sent to Zagreb where he got his first post. He lived there with his wife and his son until the capitulation of the country in 1941. A few months after the collapse of the country, he was arrested and sent to Ljubljana and three months later to a concentration camp in Austria. He spent about fifteen months in that camp in during which time he intensively studied painting. He fled from the camp to Switzerland and stayed there until his death in 1987. According to some letters he sent to his wife in Nis, some of his paintings he created during his time in the camp, ne took to Switzerland where he eventually sold them. He did the toughest jobs there in order to survive and painted extensively. After World War II he graduated from the School of Fine Arts in Lausanne. Later on he had two exhibitions at the New Gallery of Modern Art. Ivan Rančić came a long way from an unknown beginner to a respected prominent artist. He left behind about 350 works, many of which he sold during his life, mainly landscapes and still life in oil, watercolor and pastel. He was neither concerned about styles and trends nor did he believe in the old and the new. If he came to a certain specific manner of painting, it is because at one point it was imposed on him as the only proper way of expression. The analysis of Rančić's paintings leads to the conclusion that his creation had gone through four phases. The first one (started in the concentration camp in Austria during which he painted still lifes without full sketches, previous studies, and the use

    Full Text Available The article is devoted to finding typology signs in the fairy-tale by Іvan Franko that characterize works of ethology genre. Turning to the genre descriptions of this particular work is not accidental, as until now there is no clearly defined genre theory, and it is foremost explained by the fact that literary reviewers understand the nature of genre content differently. Some people see in it nothing but formal displays, and others connect it with different vital realities that attract the writer’s attention. A fully original genre conception is offered by G. Pospelov, and its basis is presented in understanding the genre range of problems such as mythological, national and historical, novel and ethological. The determined typology signs of the ethological are the following: firstly, concentration on the analysis of public environment, finding out what is considered to be a stable state, as well as the display of the dominating conduct norms. Secondly, the characters display peculiar static, inwardly immobile features; they express certain “models” of people’s behaving in different social environments. Therefore the semantic and artistic features of Ivan Franko’s fairy-tale is examined through the prism of the typology of the ethology genre; that allows to specify the understanding of concept “genre”, “literary fairy-tale as a genre”, the value of the work of ethological range of problems at the moment when a literary work is being written and in social and literary periods that follow. Displays of ethological problem range the fairy-tale are manifested in its composition nature, in peculiarities of grouping the characters; that reflects definite conflict orientation of the work and thus display of dominant traits of the main characters at least. The plot structure of the fairy-tale, namely verse, "works" for underlining the ethological range of problems: with his inserted stories Ivan Franko depicts into details the dominant

    Full Text Available The article presents the investigation of creative connections between Sergei Durylin and Ivan Shmyolev, two émigré writers of the fi rst half of the 20th century. They were brought together not only by common religious values, but also by their tragic destiny. That is why we believe the comparison of their artistic principles — through the example of Durylin’s Ancient Triptych (1919–1923 and Shmelyov’s How did it all happen? (1944 to be very productive, especially considering that no serious comparative analyze of these works has been done before. The comparison of two texts clearly shows that their problematic and poetics are quite closely connected. Both writers depict the final period of life of outwardly successful, but spiritually devastated personalities (professor of ancient history and general Patrikiy Patrikiyevich Drevlyaninov. Durylin and Shmelyov tried to help their heroes to overcome the spiritual deadlock, senselessness of existence and their personal obsessions (for the professor it is the idea of scientifi c labour corrupting the society, for the general it is gambling. Both the professor and the general travel their road of purifi cation, their ‘way of the Cross’, their Golgotha and their Resurrection. Durylin directly connects his character’s road with the liturgical cycle, because ‘fi ghting with the devil’ takes place during the Great Lent, while the grandfather sees his life-changing dream on the eve of Easter and the Passion Week. The hero’s pilgrimage to Easter forms the plot of this story, actualizing the importance of Easter archetype for Russian literature. The methods used by both authors to free their characters from spiritual emptiness (introduction of a ‘spirit character’ as a reference to the devil from Dostoyevsky’s novel The Karamazov Brothers are also similar.

    Full Text Available The article is devoted to one of the central episodes of Ivan Shmelev's short novel The Inexhaustible Chalice (Inexaustible Cup, or Non-intoxicating Chalice. The source of this episode was a legend, recorded by a priest Yakov Brilliantov. In 1912 he published the text of the legend calling it a Story of the Miraculous Icon of the Mother of God Called the “Inexhaustible Chalice”. The legend existed in the folk tradition for a long time. The paper presents a hypothesis that Ivan Shmelev reproduced an oral version or edition of the legend in his short novel. Comparison of Shmelev's novel and the old legend reveals similarities and discrepancies of texts, analysis of which can serve as the basis for important observations on lingvopoetics of the short novel and the author’s style. Ivan Shmelev uses the legend as a source of pious history: he connects it with his main text at all narrative levels, while leaving only functional elements in the recipient text. This type of creative editing can be defined as a form of a condensed narrative. Moreover, analysis of sources leads to a conclusion about the poetics of the chronotope and the main characters of the tale.

  14. Ivane S. Beritashvili (1884-1974): from spinal cord reflexes to image-driven behavior. (United States)

    Tsagareli, M G; Doty, R W


    Ivane Beritashvili ("Beritoff" in Russian, and often in Western languages) was a major figure in 20th-century neuroscience. Mastering the string galvanometer, he founded the electrophysiology of spinal cord reflexes, showing that inhibition is a distinctly different process from excitation, contrary to the concepts of his famous mentor, Wedensky. Work on postural reflexes with Magnus was cut short by World War I, but he later demonstrated that navigation in two-dimensional space without vision is a function solely of the vestibular system rather than of muscle proprioception. Persevering in his experiments despite postwar turmoil he founded an enduring Physiology Institute in Tbilisi, where he pursued an ingenious and extensive investigation of comparative memory in vertebrates. This revealed the unique nature of mammalian memory processes, which he forthrightly called "image driven," and distinguished them unequivocally from those underlying conditional reflexes. For some 30 years the Stalinist terror confined his publications to the Russian language. Work with his colleague, Chichinadze, discovering that memory confined to one cerebral hemisphere could be accessed by the other via a specific forebrain commissure, did reach the West, and ultimately led to recognition of the fascinating "split brain" condition. In the 1950s he was removed from his professorial position for 5 years as being "anti-Pavlovian." Restored to favor, he was honorary president of the "Moscow Colloquium" that saw the foundation of the International Brain Research Organization.

    Andjus, Pavle R.; Stojilkovic, Stanko S.; Cvijic, Gordana


    Summary The founder of physiology studies in the Balkans and the pioneer of research on hypothermia, Ivan Djaja (Jean Giaja) was born 1884 in L’Havre. Giaja gained his PhD at the Sorbonne in 1909. In 1910 he established the first Chair of Physiology in the Balkans and organized the first Serbian Institute for Physiology at the School of Philosophy of the University of Belgrade. He led this Institute for more than 40 subsequent years. His most notable papers were in the field of thermoregulation and bioenergetics. Djaja became member of the Serbian and Croatian academies of science and doctor honoris causa of Sorbonne. In 1952 for the seminal work on the behaviour of deep cooled warm blooded animals he becane associate member of the National Medical Academy in Paris. In 1955 the French Academy of Sciences elected him as associate member in place of deceased Sir Alexander Fleming. Djaja died in 1957 during a congress held in his honour. He left more than 200 scientific and other papers and the golden DaVincian credo “Nulla dies sine experimento”. His legacy was continued by several generations of researchers, the most prominent among them being Stefan Gelineo, Radoslav Andjus and Vojislav Petrović. PMID:21777022

    Full Text Available Na Nêmesis da Medicina, Ivan Illich expôs os elementos essenciais da sua primeira crítica da saúde, afirmando que a ampla industrialização da saúde e medicalização da vida na sociedade moderna faz aparecer diversas formas de iatrogênese ou danos à saúde, como resultado da perda da capacidade de ação autônoma das pessoas perante a enfermidade, a dor e o envelhecimento. Na segunda crítica social da saúde, Illich trata do surgimento de uma nova iatrogênese social, a iatrogênese do corpo, que resulta de uma espécie de obsessão com a saúde corporal e com sua produção através de atividades físicas, dietas etc. em aparente condição de autonomia. Trata-se de um consumismo do corpo saudável, que responde menos à ação dos médicos e mais às informações difundidas pelos meios de comunicação e pelos agentes terapêuticos não-oficiais.

  17. The industrialization of fetishism or the fetishism of industrialization: a critique of Ivan Illich. (United States)

    Navarro, V


    This article critically assesses the ideology of industrialism in light of Ivan Illich's Medical Nemesis. The paper is divided into three sections. The first section is a description of the main features of that ideology, the most prevalent and influential one used in sociological literature to explain the state both of Western societies and of our health services. Also in this section, it is shown how these features appear in Illich's analysis of our societies, of our health services, and of the different clinical, social, and structural iatrogeneses that health services create. The second section examines the assumptions underlying Illich's analysis and discusses their validity to explain the nature and function of our Western health services and their iatrogenic effects. Where Illich's explanations are considered invalid, alternative explanations are presented. Among them, it is postulated that it is not industrialism, but the assumedly transcended category of capitalism that is the cause of the social and structural iatrogeneses. The third section discusses the political implications of Illich's analysis, in a moment when our Western societies are supposedly in crisis.

  18. Slovene poetry in the U.S.A.: the case of Ivan Zorman

    Igor Maver


    Full Text Available Ivan Zorman was both a musician and a poet, born in 1889 in Šmarje near Grosuplje and died in 1957 in Cleveland (Ohio. In 1893 his family emigrated to the United States of America, first to Ely, Calumet, Cleveland and then to some other American towns. After a brief return to Slovenia in 1898/9, where Zorman attended elementary school in Velesovo near Kranj, they finally settled down in 1904 in Cleveland. In 1907 Zorman took up the study of modern languages (English, French and Italian, history and music at Western Reserve University and graduated only in music in 1912. For a number of years, during 1908 and 1956, he was chief organist and choir leader (like his father at the parish church of Sv. Lovrenc in Newburgh near Cleveland. During 1920 and 1925 he was professional director of the "Zorman Philharmonic". Not only was he known as a musician, he was very much present in the public life of the Slovene community living in Cleveland, as the enthusiastic teacher of Slovene literature in the Slovene school of the "Slovenski narodni dom", as a poet, translator and public speaker.

  19. Ivan Karamazov’s rebellion in Albert Camus’ and Karl Jaspers’ interpretations

    Directory of Open Access Journals (Sweden)

    Urszula Lisowska


    Full Text Available The aim of this study is to present Albert Camus’ and Karl Jaspers’ interpretations of Ivan Karamazov’s rebellion as the diagnoses of the weakness of the human intellect in confrontation with the world and the criticism of rationalism. Therefore, in the introduction I will present those fragments of the novel that characterize Ivan’s rebellion as highly abstract and theoretical. At the same time, this common literary context serves as the ground for reconstruction and comparison of the basic philosophical assumptions of each author. The intention of the remaining part of the paper is, firstly, to reconstruct A. Camus’ and K. Jaspers’ epistemology and, secondly, to analyse the arguments against Ivan’s attitude formulated by the writers. Their criticisms of the protagonist’s excessive trust in intellect is based on their own concepts of human epistemic capacity, which are related to the problems of the absurd in A. Camus’ and transcendence in K. Jaspers’ writings. The question of nihilism demands analysis of A. Camus’ idea of the nature of rebellion as both affirmative and negative, and of K. Jaspers’ notion of faith as pre-intellectual trust. Finally, their criticisms of the slogan “If there is no God, then anything is allowed” introduces the problem of freedom, which allows the comparison of the concepts of solidarity (A. Camus and communication (K. Jaspers. In the conclusion these two philosophical attitudes are discussed together. Keywords: ; ; ; ; ; ; ; ;

  20. Ivan Illich's Medical Nemesis and the 'age of the show': On the Expropriation of Death. (United States)

    Babich, Babette


    What Ivan Illich regarded in his Medical Nemesis as the 'expropriation of health' takes place on the surfaces and in the spaces of the screens all around us, including our cell phones but also the patient monitors and (increasingly) the iPads that intervene between nurse and patient. To explore what Illich called the 'age of the show', this essay uses film examples, like Creed and the controversial documentary Vaxxed, and the television series Nurse Jackie. Rocky's cancer in his last film (submitting to chemo to 'fight' cancer) highlights what Illich along with Petr Skrabanek called the 'expropriation of death'. In contrast to what Illich denotes as 'Umsonstigkeit' - grace or gift, given undeservedly, i.e., gratuitously - medical science tends to be tempted by what Illich terms scientistic 'black magic', taking over (expropriating) the life and the death of the patient in increasingly technological ways, a point underscored in the concluding section on the commercial prospects of xenotransplants using factory farm or mass-produced human-pig mosaics or chimeras. © 2018 John Wiley & Sons Ltd.

  1. Perception in statistical graphics (United States)

    VanderPlas, Susan Ruth

    There has been quite a bit of research on statistical graphics and visualization, generally focused on new types of graphics, new software to create graphics, interactivity, and usability studies. Our ability to interpret and use statistical graphics hinges on the interface between the graph itself and the brain that perceives and interprets it, and there is substantially less research on the interplay between graph, eye, brain, and mind than is sufficient to understand the nature of these relationships. The goal of the work presented here is to further explore the interplay between a static graph, the translation of that graph from paper to mental representation (the journey from eye to brain), and the mental processes that operate on that graph once it is transferred into memory (mind). Understanding the perception of statistical graphics should allow researchers to create more effective graphs which produce fewer distortions and viewer errors while reducing the cognitive load necessary to understand the information presented in the graph. Taken together, these experiments should lay a foundation for exploring the perception of statistical graphics. There has been considerable research into the accuracy of numerical judgments viewers make from graphs, and these studies are useful, but it is more effective to understand how errors in these judgments occur so that the root cause of the error can be addressed directly. Understanding how visual reasoning relates to the ability to make judgments from graphs allows us to tailor graphics to particular target audiences. In addition, understanding the hierarchy of salient features in statistical graphics allows us to clearly communicate the important message from data or statistical models by constructing graphics which are designed specifically for the perceptual system.

  2. Safety and design impact of hurricane Andrew

    International Nuclear Information System (INIS)

    Guey, Ching N.


    Turkey Point completed the IPE in June of 1991. Hurricane Andrew landed at Turkey Point on August 24, 1992. Although the safety related systems, components and structures were not damaged by the Hurricane Andrew, certain nonsafety related components and the neighboring fossil plant sustained noticeable damage. Among the major components that were nonsafety related but would affect the PRA of the plant included the service water pumps and the high tower. This paper discusses the safety and design impact of Hurricane Andrew on Turkey Point Nuclear Power Plant. The risk of hurricanes on the interim and evolving plant configurations are briefly described. The risk of the plant from internal events as a result of damage incurred during Hurricane Andrew are discussed. The design change as the result of Hurricane Andrew and its impact on the PRA are presented. (author)

  7. Illustrations to “Gespräche in dem Reiche derer Todten zwischen dem vortreflichen Moscowitischen Czaar Petro Magno und dem grossen Tyrannen Ivan Basilowiz II” (Peter the Great and Ivan the Terrible by David Fassmann (1725

    Directory of Open Access Journals (Sweden)

    Ekaterina A. Skvortcova


    Full Text Available The journal created by David Fassmann (1683–1744, Gespräche in dem Reiche derer Todten, edited in Leipzig, was a huge success. Each of the 240 issues presents a dialogue between two historical figures from the afterworld. In the 83rd–86th Entrevuë, the interlocutors are Peter the Great and Ivan the Terrible. The texts of the four conversations were thoroughly examined by Eckhard Matthes (1987. The present paper explores how the illustrations to the 83rd–86th Entrevuë visualize the texts, which is significant as they were an important instrument for disseminating certain notions about Russia. While the illustration to the first dialogue of the suite juxtaposes Peter and Ivan, the illustration to the second one emphasizes the similarities between them. So the image of the “tyrant” and “barbarian” Ivan becomes a reference point with which a reader is urged to compare Peter’s deeds, seeing not only the differences but also the similarities. This greatly contributes to the creation of the multifaceted image of Russia of the early 18th century. The characters of the second illustration—a tiger and an executioner—can be identified as Ivan and Peter only if the reader takes into consideration an epigram to the illustration, the illustration to the previous dialogue, the text of the next Entrevuë, and facts about the execution of the strel’tsy known from other texts and images, about which Fassmann remains silent in the spirit of ars dissimulandi, which was typical for baroque culture. The paper offers an attempt to trace the iconography of the tyrant as a tiger. In the frontispiece to the 85th Entrevuë, a secretary bringing news from the world of the living and a portrait of Catherine I emphasize the connection of the past and the present, i.e., history and policy. Finally, the illustration to the last dialogue of the series returns to the glorification of Peter the Great declared in the first dialogue.

  9. Lessons Learnt From Hurricane Katrina. (United States)

    Akundi, Murty


    Hurricane Katrina devastated New Orleans and its suburbs on Monday August 29^th, 2005. The previous Friday morning, August 26, the National Hurricane Center indicated that Katrina was a Category One Hurricane, which was expected to hit Florida. By Friday afternoon, it had changed its course, and neither the city nor Xavier University was prepared for this unexpected turn in the hurricane's path. The university had 6 to 7 ft of water in every building and Xavier was closed for four months. Students and university personnel that were unable to evacuate were trapped on campus and transportation out of the city became a logistical nightmare. Email and all electronic systems were unavailable for at least a month, and all cell phones with a 504 area code stopped working. For the Department, the most immediate problem was locating faculty and students. Xavier created a list of faculty and their new email addresses and began coordinating with faculty. Xavier created a web page with advice for students, and the chair of the department created a separate blog with contact information for students. The early lack of a clear method of communication made worse the confusion and dismay among the faculty on such issues as when the university would reopen, whether the faculty would be retained, whether they should seek temporary (or permanent) employment elsewhere, etc. With the vision and determination of President Dr. Francis, Xavier was able to reopen the university in January and ran a full academic year from January through August. Since Katrina, the university has asked every department and unit to prepare emergency preparedness plans. Each department has been asked to collect e-mail addresses (non-Xavier), cell phone numbers and out of town contact information. The University also established an emergency website to communicate. All faculty have been asked to prepare to teach classes electronically via Black board or the web. Questions remain about the longer term issues of

  10. Hurricane feedback research may improve intensity forecasts (United States)

    Schultz, Colin


    Forecasts of a hurricane's intensity are generally much less accurate than forecasts of its most likely path. Large-scale atmospheric patterns dictate where a hurricane will go and how quickly it will get there. The storm's intensity, however, depends on small-scale shifts in atmospheric stratification, upwelling rates, and other transient dynamics that are difficult to predict. Properly understanding the risk posed by an impending storm depends on having a firm grasp of all three properties: translational speed, intensity, and path. Drawing on 40 years of hurricane records representing 3090 different storms, Mei et al. propose that a hurricane's translational speed and intensity may be closely linked.

  12. Modeling lost production from destroyed platforms in the 2004-2005 Gulf of Mexico hurricane seasons

    International Nuclear Information System (INIS)

    Kaiser, Mark J.; Yu, Yunke; Jablonowski, Christopher J.


    Hurricanes Ivan, Katrina, and Rita passed through the Gulf of Mexico during 2004 and 2005 and resulted in the largest number of destroyed and damaged offshore oil and gas structures in the history of Gulf operations. In the final official government assessment, a total of 126 platforms were destroyed and over 183 structures were identified as having extensive damage. Production associated with wells and structures that are not redeveloped are classified as lost. The purpose of this paper is to derive functional relations that describe the likely contribution the collection of destroyed assets would have made to future production in the Gulf of Mexico. We estimate that the total remaining reserves from the set of destroyed structures range in value between 1.3 and 4.5 billion depending on the assumptions employed. We summarize the impact of the storms on the Gulf of Mexico oil and gas infrastructure and discuss the main issues involved in redevelopment decision making. A meta-model analytic framework is applied to perform sensitivity analysis and to explore the interactions of assumptions on model output. A discussion of the limitations of the analysis is presented. (author)

  13. Two-dimensional time dependent hurricane overwash and erosion modeling at Santa Rosa Island (United States)

    McCall, R.T.; Van Theil de Vries, J. S. M.; Plant, N.G.; Van Dongeren, A. R.; Roelvink, J.A.; Thompson, D.M.; Reniers, A.J.H.M.


    A 2DH numerical, model which is capable of computing nearshore circulation and morphodynamics, including dune erosion, breaching and overwash, is used to simulate overwash caused by Hurricane Ivan (2004) on a barrier island. The model is forced using parametric wave and surge time series based on field data and large-scale numerical model results. The model predicted beach face and dune erosion reasonably well as well as the development of washover fans. Furthermore, the model demonstrated considerable quantitative skill (upwards of 66% of variance explained, maximum bias - 0.21 m) in hindcasting the post-storm shape and elevation of the subaerial barrier island when a sheet flow sediment transport limiter was applied. The prediction skill ranged between 0.66 and 0.77 in a series of sensitivity tests in which several hydraulic forcing parameters were varied. The sensitivity studies showed that the variations in the incident wave height and wave period affected the entire simulated island morphology while variations in the surge level gradient between the ocean and back barrier bay affected the amount of deposition on the back barrier and in the back barrier bay. The model sensitivity to the sheet flow sediment transport limiter, which served as a proxy for unknown factors controlling the resistance to erosion, was significantly greater than the sensitivity to the hydraulic forcing parameters. If no limiter was applied the simulated morphological response of the barrier island was an order of magnitude greater than the measured morphological response.

    Secretan, Y.

    A discussion of the modular program Mikado is presented. Mikado was developed with the goal of creating a flexible graphic tool to display and help analyze the results of finite element fluid flow computations. Mikado works on unstructured meshes, with elements of mixed geometric type, but also offers the possibility of using structured meshes. The program can be operated by both menu and mouse (interactive), or by command file (batch). Mikado is written in FORTRAN, except for a few system dependent subroutines which are in C. It runs presently on Silicon Graphics' workstations and could be easily ported to the IBM-RISC System/6000 family of workstations.

    Jon Igelmo Zaldívar


    Full Text Available Shortly after its publication in 1971, Ivan Illich’s Deschooling Society made a significant impact on reports written at the most influential levels of international institutions, such as Edgar Faure’s report for UNSECO, titled Learning to Be: The World of Education Today and Tomorrow (1972. However, Deschooling Society is but one of many aspects in the overall set of criticisms Illich constructed regarding education and its institutions throughout his entire career. With this matter in mind, this article presents a study on the usefulness of Illich’s thoughts on education and its institutions in the debate on the «post-2015 agenda» being promoted by organisations such as UNESCO and the World Bank. The aim is to reclaim this author’s works as key referents in the questioning of the theoretical grounds predominating many international development policies that advocate «Education for All» and «Learning for All» in the 21st century.How to reference this articleIgelmo Zaldívar, J.

  18. The Status of Kasimov Chinggisids during the Reigns of Vasily II and Ivan III according to Written Sources

    Directory of Open Access Journals (Sweden)

    M.A. Nesin


    Full Text Available Research objective: To study the issue both of the status of Kasimov Chinggisids as well as of the attitude toward the service Tatars and the Tatars who were allied to Moscow during the reigns of the great Moscow princes Vasily II and Ivan III. Research materials: Published and unpublished sources: books of official orders in the Russian state, chronicles, acts, diplomatic documents, etc. Results and novelty of the research: This work is the first comprehensive study of this topic. The author comes to the conclusion that Kasimov’s rulers during this period were considered servitors, vassals in relation to the Moscow principality. This was facilitated by the demesnial position of Kasimov, which was considered part of the grand prince’s domain rather than a sovereign splinter of the Golden Horde. Kasimov Chinggisids did not have a large military force in order to create an independent khanate in the steppe capable of competing, for example, with Kazan, and they relied on the strong Moscow principality performing military service for it, receiving money for proper maintenance and obeying the grand prince’s orders. At the same time, Ivan III even considered the possibility of replacing Daniyar in Kasimov with another serving prince during his lifetime. In addition, the author shows how much the attitude towards the service Tatars and the Tatar detachments, who were allied to Moscow, differed in different Russian lands.

  19. Genesis of tornadoes associated with hurricanes (United States)

    Gentry, R. C.


    The climatological history of hurricane-tornadoes is brought up to date through 1982. Most of the tornadoes either form near the center of the hurricane, from the outer edge of the eyewall outward, or in an area between north and east-southeast of the hurricane center. The blackbody temperatures of the cloud tops which were analyzed for several hurricane-tornadoes that formed in the years 1974, 1975, and 1979, did not furnish strong precursor signals of tornado formation, but followed one of two patterns: either the temperatures were very low, or the tornado formed in areas of strong temperature gradients. Tornadoes with tropical cyclones most frequently occur at 1200-1800 LST, and although most are relatively weak, they can reach the F3 intensity level. Most form in association with the outer rainbands of the hurricane.

  8. Hurricane shuts down gulf activity

    International Nuclear Information System (INIS)

    Koen, A.D.


    This paper reports that producers in the Gulf of Mexico and plant operators in South Louisiana last week were checking for damage wrought by Hurricane Andrew. In its wake Andrew left evacuated rigs and platforms in the gulf and shuttered plants across a wide swath of the Gulf Coast. Operations were beginning to return to normal late last week. Not all gulf operators, especially in the central gulf, expected to return to offshore facilities. And even producers able to book helicopters did not expect to be able to fully assess damage to all offshore installations before the weekend. MMS officials in Washington estimated that 37,500 offshore workers were evacuated from 700 oil and gas installations on the gulf's Outer Continental Shelf. Gulf oil and gas wells account for about 800,000 b/d of oil and one fourth of total U.S. gas production. MMS was awaiting an assessment of hurricane damage before estimating how soon and how much gulf oil and gas production would be restored

  11. Estimating cellular network performance during hurricanes

    International Nuclear Information System (INIS)

    Booker, Graham; Torres, Jacob; Guikema, Seth; Sprintson, Alex; Brumbelow, Kelly


    Cellular networks serve a critical role during and immediately after a hurricane, allowing citizens to contact emergency services when land-line communication is lost and serving as a backup communication channel for emergency responders. However, due to their ubiquitous deployment and limited design for extreme loading events, basic network elements, such as cellular towers and antennas are prone to failures during adverse weather conditions such as hurricanes. Accordingly, a systematic and computationally feasible approach is required for assessing and improving the reliability of cellular networks during hurricanes. In this paper we develop a new multi-disciplinary approach to efficiently and accurately assess cellular network reliability during hurricanes. We show how the performance of a cellular network during and immediately after future hurricanes can be estimated based on a combination of hurricane wind field models, structural reliability analysis, Monte Carlo simulation, and cellular network models and simulation tools. We then demonstrate the use of this approach for assessing the improvement in system reliability that can be achieved with discrete topological changes in the system. Our results suggest that adding redundancy, particularly through a mesh topology or through the addition of an optical fiber ring around the perimeter of the system can be an effective way to significantly increase the reliability of some cellular systems during hurricanes.

    McLaughlin, Katie A; Berglund, Patricia; Gruber, Michael J; Kessler, Ronald C; Sampson, Nancy A; Zaslavsky, Alan M


    We examined patterns and correlates of speed of recovery of estimated posttraumatic stress disorder (PTSD) among people who developed PTSD in the wake of Hurricane Katrina. A probability sample of prehurricane residents of areas affected by Hurricane Katrina was administered a telephone survey 7-19 months following the hurricane and again 24-27 months posthurricane. The baseline survey assessed PTSD using a validated screening scale and assessed a number of hypothesized predictors of PTSD recovery that included sociodemographics, prehurricane history of psychopathology, hurricane-related stressors, social support, and social competence. Exposure to posthurricane stressors and course of estimated PTSD were assessed in a follow-up interview. An estimated 17.1% of respondents had a history of estimated hurricane-related PTSD at baseline and 29.2% by the follow-up survey. Of the respondents who developed estimated hurricane-related PTSD, 39.0% recovered by the time of the follow-up survey with a mean duration of 16.5 months. Predictors of slow recovery included exposure to a life-threatening situation, hurricane-related housing adversity, and high income. Other sociodemographics, history of psychopathology, social support, social competence, and posthurricane stressors were unrelated to recovery from estimated PTSD. The majority of adults who developed estimated PTSD after Hurricane Katrina did not recover within 18-27 months. Delayed onset was common. Findings document the importance of initial trauma exposure severity in predicting course of illness and suggest that pre- and posttrauma factors typically associated with course of estimated PTSD did not influence recovery following Hurricane Katrina. © 2011 Wiley-Liss, Inc.

    Full Text Available This paper examines graphic journalism (GJ in a transmedial context, and argues that transmedial graphic journalism (TMGJ is an important and fruitful new form of visual storytelling, that will re-invigorate the field of journalism, as it steadily tests out and plays with new media, ultimately leading to new challenges in both the production and reception process. With TMGJ, linear narratives may be broken up and ethical issues concerning the emotional and entertainment value are raised when it comes to ‘playing the news’. The aesthetic characteristics of TMGJ will be described and interactivity’s influence on non-fiction storytelling will be explored in an analysis of The Nisoor Square Shooting (2011 and Ferguson Firsthand (2015.

  17. The effect of proximity to hurricanes Katrina and Rita on subsequent hurricane outlook and optimistic bias. (United States)

    Trumbo, Craig; Lueck, Michelle; Marlatt, Holly; Peek, Lori


    This study evaluated how individuals living on the Gulf Coast perceived hurricane risk after Hurricanes Katrina and Rita. It was hypothesized that hurricane outlook and optimistic bias for hurricane risk would be associated positively with distance from the Katrina-Rita landfall (more optimism at greater distance), controlling for historically based hurricane risk and county population density, demographics, individual hurricane experience, and dispositional optimism. Data were collected in January 2006 through a mail survey sent to 1,375 households in 41 counties on the coast (n = 824, 60% response). The analysis used hierarchal regression to test hypotheses. Hurricane history and population density had no effect on outlook; individuals who were male, older, and with higher household incomes were associated with lower risk perception; individual hurricane experience and personal impacts from Katrina and Rita predicted greater risk perception; greater dispositional optimism predicted more optimistic outlook; distance had a small effect but predicted less optimistic outlook at greater distance (model R(2) = 0.21). The model for optimistic bias had fewer effects: age and community tenure were significant; dispositional optimism had a positive effect on optimistic bias; distance variables were not significant (model R(2) = 0.05). The study shows that an existing measure of hurricane outlook has utility, hurricane outlook appears to be a unique concept from hurricane optimistic bias, and proximity has at most small effects. Future extension of this research will include improved conceptualization and measurement of hurricane risk perception and will bring to focus several concepts involving risk communication. © 2011 Society for Risk Analysis.

    Guynn, J B


    Response to a disaster situation depends upon the type of circumstances presented. In situations where the disaster is the type that affects the hospital as well as a wide surrounding area directly, the hospital and pharmacy itself may be called upon to continue functioning for some period of time without outside assistance. The ability to function for prolonged periods of time requires the staff to focus on the job at hand and the administrative staff to provide security, compassion, and flexibility. Plans for a disaster of the nature of a hurricane require that attention be paid to staffing, medication inventories, supplies, and services being rendered. Recognition of the singular position occupied by a hospital in the community and the expectations of the local population require that hospitals and the pharmacy department have the ability to respond appropriately.

  9. Tsunamis and Hurricanes A Mathematical Approach

    CERN Document Server

    Cap, Ferdinand


    Tsunamis and hurricanes have had a devastating impact on the population living near the coast during the year 2005. The calculation of the power and intensity of tsunamis and hurricanes are of great importance not only for engineers and meteorologists but also for governments and insurance companies. This book presents new research on the mathematical description of tsunamis and hurricanes. A combination of old and new approaches allows to derive a nonlinear partial differential equation of fifth order describing the steepening up and the propagation of tsunamis. The description includes dissipative terms and does not contain singularities or two valued functions. The equivalence principle of solutions of nonlinear large gas dynamics waves and of solutions of water wave equations will be used. An extension of the continuity equation by a source term due to evaporation rates of salt seawater will help to understand hurricanes. Detailed formula, tables and results of the calculations are given.

  11. Spatial grids for hurricane climate research

    Energy Technology Data Exchange (ETDEWEB)

    Elsner, James B.; Hodges, Robert E.; Jagger, Thomas H. [Florida State University, Tallahassee, FL (United States)


    The authors demonstrate a spatial framework for studying hurricane climatology. The framework consists of a spatial tessellation of the hurricane basin using equal-area hexagons. The hexagons are efficient at covering hurricane tracks and provide a scaffolding to combine attribute data from tropical cyclones with spatial climate data. The framework's utility is demonstrated using examples from recent hurricane seasons. Seasons that have similar tracks are quantitatively assessed and grouped. Regional cyclone frequency and intensity variations are mapped. A geographically-weighted regression of cyclone intensity on sea-surface temperature emphasizes the importance of a warm ocean in the intensification of cyclones over regions where the heat content is greatest. The largest differences between model predictions and observations occur near the coast. The authors suggest the framework is ideally suited for comparing tropical cyclones generated from different numerical simulations. (orig.)

  12. Isentropic Analysis of a Simulated Hurricane (United States)

    Mrowiec, Agnieszka A.; Pauluis, Olivier; Zhang, Fuqing


    Hurricanes, like many other atmospheric flows, are associated with turbulent motions over a wide range of scales. Here the authors adapt a new technique based on the isentropic analysis of convective motions to study the thermodynamic structure of the overturning circulation in hurricane simulations. This approach separates the vertical mass transport in terms of the equivalent potential temperature of air parcels. In doing so, one separates the rising air parcels at high entropy from the subsiding air at low entropy. This technique filters out oscillatory motions associated with gravity waves and separates convective overturning from the secondary circulation. This approach is applied here to study the flow of an idealized hurricane simulation with the Weather Research and Forecasting (WRF) Model. The isentropic circulation for a hurricane exhibits similar characteristics to that of moist convection, with a maximum mass transport near the surface associated with a shallow convection and entrainment. There are also important differences. For instance, ascent in the eyewall can be readily identified in the isentropic analysis as an upward mass flux of air with unusually high equivalent potential temperature. The isentropic circulation is further compared here to the Eulerian secondary circulation of the simulated hurricane to show that the mass transport in the isentropic circulation is much larger than the one in secondary circulation. This difference can be directly attributed to the mass transport by convection in the outer rainband and confirms that, even for a strongly organized flow like a hurricane, most of the atmospheric overturning is tied to the smaller scales.

    Starting from Zermelo’s classical formal treatment of chess, we trace through history the analysis of two-player win/lose/draw games with perfect information and potentially infinite play. Such chess-like games have appeared in many different research communities, and methods for solving them......, such as retrograde analysis, have been rediscovered independently. We then revisit Washburn’s deterministic graphical games (DGGs), a natural generalization of chess-like games to arbitrary zero-sum payoffs. We study the complexity of solving DGGs and obtain an almost-linear time comparison-based algorithm...

    Vienne, Véronique


    Can you objectify a subjective notion? This is the question graphic designers must face when they talk about their work. Even though graphic design artifacts are omnipresent in our culture, graphic design is still an exceptionally ill-defined profession. This is one of the reasons design criticism is still a rudimentary discipline. No one knows for sure what is this thing we sometimes call “graphic communication” for lack of a better word–a technique my Webster’s dictionary describes as “the ...

    In all personal computer applications, be it for private or professional use, the decision of which "brand" of computer to buy is of central importance. In the USA Apple computers are mainly used in universities, while in Europe computers of the so-called "industry standard" by IBM (or clones thereof) have been increasingly used for many years. Independently of any brand name considerations, the computer components purchased must meet the current (and projected) needs of the user. Graphic capabilities and standards, processor speed, the use of co-processors, as well as input and output devices such as "mouse", printers and scanners are discussed. This overview is meant to serve as a decision aid. Potential users are given a short but detailed summary of current technical features.

    This paper analyses five hurricanes that occurred in the period 1600 to 1800. These examples were identified during a systematic search in the General Archive of the Indies (AGI) in Seville. The research combined the expertise of climatologists and historians in order to optimise the search and analysis strategies. Results demonstrate the potential of this archive for the assessment of hurricanes in this period and show some of the difficulties involved in the collection of evidence of hurricane activity. The documents provide detailed descriptions of a hurricane's impacts and allow us to identify previously unreported hurricanes, obtain more precise dates for hurricanes previously identified, better define the area affected by a given hurricane and, finally, better assess a hurricane's intensity.

    Full Text Available Teorii și practice ale integrării europene [Theories and Practices of European Integration] is a genuine contribution to understanding how the European Union’s particular character has been adjusted in more than half of century of institutional growth and development. Professor Ivan`s key argument for this book is that the European Union has been shaped as a functional project taking into consideration the diverse heritage and traditions of its Member States. The opening chapter of this book focuses on the particularities of international relations discipline after the Second World War in order to introduce the theme of European Integration Process. This chapter must be analysed in a series of contributions dedicated to the European Integration process and to the theories that made this integration possible because professor Ivan has previously published books such as: Statele Unite ale Europei [The United States of Europe], Sub zodia Statelor Unite ale Europei [Under the Sign of the United States of Europe], in which he debates the origins of the European construction and brings forward arguments to support the importance of each theoretical and functional pillar of this “Common European Project”.

  13. Evaluation of TRIGRS (transient rainfall infiltration and grid-based regional slope-stability analysis)'s predictive skill for hurricane-triggered landslides: A case study in Macon County, North Carolina (United States)

    Liao, Z.; Hong, Y.; Kirschbaum, D.; Adler, R.F.; Gourley, J.J.; Wooten, R.


    The key to advancing the predictability of rainfall-triggered landslides is to use physically based slope-stability models that simulate the transient dynamical response of the subsurface moisture to spatiotemporal variability of rainfall in complex terrains. TRIGRS (transient rainfall infiltration and grid-based regional slope-stability analysis) is a USGS landslide prediction model, coded in Fortran, that accounts for the influences of hydrology, topography, and soil physics on slope stability. In this study, we quantitatively evaluate the spatiotemporal predictability of a Matlab version of TRIGRS (MaTRIGRS) in the Blue Ridge Mountains of Macon County, North Carolina where Hurricanes Ivan triggered widespread landslides in the 2004 hurricane season. High resolution digital elevation model (DEM) data (6-m LiDAR), USGS STATSGO soil database, and NOAA/NWS combined radar and gauge precipitation are used as inputs to the model. A local landslide inventory database from North Carolina Geological Survey is used to evaluate the MaTRIGRS' predictive skill for the landslide locations and timing, identifying predictions within a 120-m radius of observed landslides over the 30-h period of Hurricane Ivan's passage in September 2004. Results show that within a radius of 24 m from the landslide location about 67% of the landslide, observations could be successfully predicted but with a high false alarm ratio (90%). If the radius of observation is extended to 120 m, 98% of the landslides are detected with an 18% false alarm ratio. This study shows that MaTRIGRS demonstrates acceptable spatiotemporal predictive skill for landslide occurrences within a 120-m radius in space and a hurricane-event-duration (h) in time, offering the potential to serve as a landslide warning system in areas where accurate rainfall forecasts and detailed field data are available. The validation can be further improved with additional landslide information including the exact time of failure for each

    Full Text Available In Tolstoy’s stories of the 1870s the coloratives have negative semantics. In “The Death of Ivan Ilyich” the yellow color “implicates” a movement to death. In “The Kreutzer Sonata” this color aggravates Pozdnyshev’s moral sufferings and embodies deception and lust. In “The Devil” the description of Lisa’s yellow complexion reveals Irtenev’s negative attitude to her. In “The Death of Ivan Ilyich” the pink and green cretonne of a “fashionable” living room loses its grandiosity in the house of the deceased man. In “The Death of Ivan Ilyich” the white color of clothes initially associated by the character with confidence in the future, then resulted in the patient’s dislike and was seen as evidence of inconsiderateness of people. In “The Kreutzer Sonata” the white color, in Trukhachevsky’s portrait, turned Pozdnyshev against him even more. In “The Devil” the white color Lisa was accompanied with provoked the growth of Irtenev’s irritation. In “The Kreutzer Sonata” the semantics of the red color is disturbing, ominous, and associated with debauchery and lie. In “The Devil” the description of the red clothes replaces the portrait characteristics of Stepanida; for Irtenev the red panyova and the red headscarf of his mistress became the symbols of the devilish temptation. In “The Death of Ivan Ilyich” the black color, being an attribute of mental and physical illness of the character, began to correspond to the image of a black sack devouring the person. In “The Kreutzer Sonata” an infernal black and red color scale contributes to the presentiment of tragedy. In “The Devil” the black color discovers Irtenev’s increasing dependence on delusion. In “The Kreutzer Sonata” the coloratives with the root “light” are related to Pozdnyshev’s insight concerning his family life, based on deception. In “The Death of Ivan Ilyich” “light” liberates the character of death anxiety

    Full Text Available This paper looks at the circumstances in which Ivan Crnojević, a fifteenth-century ruler of Zeta (historic region in present-day Montenegro, made a vow to the Virgin in a famous pilgrimage shrine, the Santa Casa in Loreto (Italy, where he was in exile fleeing another Ottoman offensive. The focus of the paper is on a few issues which need to be re-examined in order to understand Ivan’s vow against a broader background. His act is analyzed in the context of the symbolic role that the Virgin of Loreto played as a powerful antiturca protectress. On the other hand, much attention is paid to the institutional organization of Slavs (Schiavoni who found refuge in Loreto and nearby towns, which may serve as a basis for a more comprehensive understanding of the process of religious and social adjustment of Orthodox Slav refugees to their new Catholic environment.

    Electroencephalography (EEG) is a novel modality for investigating perceptual graphics problems. Until recently, EEG has predominantly been used for clinical diagnosis, in psychology, and by the brain-computer-interface community. Researchers are extending it to help understand the perception of visual output from graphics applications and to create approaches based on direct neural feedback. Researchers have applied EEG to graphics to determine perceived image and video quality by detecting typical rendering artifacts, to evaluate visualization effectiveness by calculating the cognitive load, and to automatically optimize rendering parameters for images and videos on the basis of implicit neural feedback.

  4. On the Influence of Global Warming on Atlantic Hurricane Frequency (United States)

    Hosseini, S. R.; Scaioni, M.; Marani, M.


    In this paper, the possible connection between the frequency of Atlantic hurricanes to the climate change, mainly the variation in the Atlantic Ocean surface temperature has been investigated. The correlation between the observed hurricane frequency for different categories of hurricane's intensity and Sea Surface Temperature (SST) has been examined over the Atlantic Tropical Cyclogenesis Regions (ACR). The results suggest that in general, the frequency of hurricanes have a high correlation with SST. In particular, the frequency of extreme hurricanes with Category 5 intensity has the highest correlation coefficient (R = 0.82). In overall, the analyses in this work demonstrates the influence of the climate change condition on the Atlantic hurricanes and suggest a strong correlation between the frequency of extreme hurricanes and SST in the ACR.

    Stereoscopic display technology is one of the key techniques of areas such as simulation, multimedia, entertainment, virtual reality, and so on. Moreover, stereoscopic 3D graphics generation is an important part of stereoscopic 3D display system. In this paper, at first, we describe the principle of stereoscopic display and summarize some methods to generate stereoscopic 3D graphics. Secondly, to overcome the problems which came from the methods of user defined models (such as inconvenience, long modifying period and so on), we put forward the vector graphics files defined method. Thus we can design more directly; modify the model simply and easily; generate more conveniently; furthermore, we can make full use of graphics accelerator card and so on. Finally, we discuss the problem of how to speed up the generation.

    Stuart, Douglas G; Schaefer, Andreas T; Massion, Jean; Graham, Brett A; Callister, Robert J


    This article reviews the contributions of Ivan Michailovich Sechenov [1829-1905] to the neurophysiological concept of central inhibition. He first studied this concept in the frog and on himself. Later his trainees extended the study of central inhibition to other mammalian species. Outside his own country, Sechenov is better known for his prescient contributions to physiological psychology. In Russia, however, he is also revered as "the father of Russian physiology," because of his contributions to neurophysiology and other aspects of physiology including blood gases and respiration, the physiology and biomechanics of movement, and general physiology concepts that appeared in his textbooks and later works he helped translate from largely German sources. After graduation from Moscow University Medical School in 1856 he spent 3½ years in Germany and Austria where he attended lectures and conducted research under the direction of several prominent physiologists and biochemists. In his subsequent academic career he held positions at universities in St. Petersburg (1860-1870; 1876-1888), Odessa (1871-1876) and Moscow (1890-1905). From 1860 onwards he was acclaimed as a physiologist in academic circles. He was also well known in Russian society for his public lectures on physiology and his views on physiological psychology. The latter resulted in him being branded "politically unreliable" by the tsarist bureaucracy from 1863 onwards. Sechenov's first (1862) study on central inhibition remains his most memorable. He delayed the withdrawal of a frog's foot from a weak acid solution by chemical or electrical stimulation of selected parts of the central nervous system. He also noted similar effects on his own hand during co-activation of other sensory inputs by tickling or teeth gnashing. Copyright © 2013 Elsevier B.V. All rights reserved.

  5. Hurricane Harvey Riverine Flooding: Part 1 - Reconstruction of Hurricane Harvey Flooding for Harris County, TX using a GPU-accelerated 2D flood model for post-flood hazard analysis (United States)

    Kalyanapu, A. J.; Dullo, T. T.; Gangrade, S.; Kao, S. C.; Marshall, R.; Islam, S. R.; Ghafoor, S. K.


    Hurricane Harvey that made landfall in the southern Texas this August is one of the most destructive hurricanes during the 2017 hurricane season. During its active period, many areas in coastal Texas region received more than 40 inches of rain. This downpour caused significant flooding resulting in about 77 casualties, displacing more than 30,000 people, inundating hundreds of thousands homes and is currently estimated to have caused more than $70 billion in direct damage. One of the significantly affected areas is Harris County where the city of Houston, TX is located. Covering over two HUC-8 drainage basins ( 2702 mi2), this county experienced more than 80% of its annual average rainfall during this event. This study presents an effort to reconstruct flooding caused by extreme rainfall due to Hurricane Harvey in Harris County, Texas. This computationally intensive task was performed at a 30-m spatial resolution using a rapid flood model called Flood2D-GPU, a graphics processing unit (GPU) accelerated model, on Oak Ridge National Laboratory's (ORNL) Titan Supercomputer. For this task, the hourly rainfall estimates from the National Center for Environmental Prediction Stage IV Quantitative Precipitation Estimate were fed into the Variable Infiltration Capacity (VIC) hydrologic model and Routing Application for Parallel computation of Discharge (RAPID) routing model to estimate flow hydrographs at 69 locations for Flood2D-GPU simulation. Preliminary results of the simulation including flood inundation extents, maps of flood depths and inundation duration will be presented. Future efforts will focus on calibrating and validating the simulation results and assessing the flood damage for better understanding the impacts made by Hurricane Harvey.

  6. Mapping and Visualization of Storm-Surge Dynamics for Hurricane Katrina and Hurricane Rita (United States)

    Gesch, Dean B.


    The damages caused by the storm surges from Hurricane Katrina and Hurricane Rita were significant and occurred over broad areas. Storm-surge maps are among the most useful geospatial datasets for hurricane recovery, impact assessments, and mitigation planning for future storms. Surveyed high-water marks were used to generate a maximum storm-surge surface for Hurricane Katrina extending from eastern Louisiana to Mobile Bay, Alabama. The interpolated surface was intersected with high-resolution lidar elevation data covering the study area to produce a highly detailed digital storm-surge inundation map. The storm-surge dataset and related data are available for display and query in a Web-based viewer application. A unique water-level dataset from a network of portable pressure sensors deployed in the days just prior to Hurricane Rita's landfall captured the hurricane's storm surge. The recorded sensor data provided water-level measurements with a very high temporal resolution at surveyed point locations. The resulting dataset was used to generate a time series of storm-surge surfaces that documents the surge dynamics in a new, spatially explicit way. The temporal information contained in the multiple storm-surge surfaces can be visualized in a number of ways to portray how the surge interacted with and was affected by land surface features. Spatially explicit storm-surge products can be useful for a variety of hurricane impact assessments, especially studies of wetland and land changes where knowledge of the extent and magnitude of storm-surge flooding is critical.

  7. Multi-hazard risk analysis related to hurricanes (United States)

    Lin, Ning

    Hurricanes present major hazards to the United States. Associated with extreme winds, heavy rainfall, and storm surge, landfalling hurricanes often cause enormous structural damage to coastal regions. Hurricane damage risk assessment provides the basis for loss mitigation and related policy-making. Current hurricane risk models, however, often oversimplify the complex processes of hurricane damage. This dissertation aims to improve existing hurricane risk assessment methodology by coherently modeling the spatial-temporal processes of storm landfall, hazards, and damage. Numerical modeling technologies are used to investigate the multiplicity of hazards associated with landfalling hurricanes. The application and effectiveness of current weather forecasting technologies to predict hurricane hazards is investigated. In particular, the Weather Research and Forecasting model (WRF), with Geophysical Fluid Dynamics Laboratory (GFDL)'s hurricane initialization scheme, is applied to the simulation of the wind and rainfall environment during hurricane landfall. The WRF model is further coupled with the Advanced Circulation (AD-CIRC) model to simulate storm surge in coastal regions. A case study examines the multiple hazards associated with Hurricane Isabel (2003). Also, a risk assessment methodology is developed to estimate the probability distribution of hurricane storm surge heights along the coast, particularly for data-scarce regions, such as New York City. This methodology makes use of relatively simple models, specifically a statistical/deterministic hurricane model and the Sea, Lake and Overland Surges from Hurricanes (SLOSH) model, to simulate large numbers of synthetic surge events, and conducts statistical analysis. The estimation of hurricane landfall probability and hazards are combined with structural vulnerability models to estimate hurricane damage risk. Wind-induced damage mechanisms are extensively studied. An innovative windborne debris risk model is

    Kerry Milch


    Full Text Available Although the field has seen great advances in hurricane prediction and response, the economic toll from hurricanes on U.S. communities continues to rise. We present data from Hurricanes Earl (2010, Irene (2011, Isaac (2012, and Sandy (2012 to show that individual and household decisions contribute to this vulnerability. From phone surveys of residents in communities threatened by impending hurricanes, we identify five decision biases or obstacles that interfere with residents’ ability to protect themselves and minimize property damage: (1 temporal and spatial myopia, (2 poor mental models of storm risk, (3 gaps between objective and subjective probability estimates, (4 prior storm experience, and (5 social factors. We then discuss ways to encourage better decision making and reduce the economic and emotional impacts of hurricanes, using tools such as decision defaults (requiring residents to opt out of precautions rather than opt in and tailoring internet-based forecast information so that it is local, specific, and emphasizes impacts rather than probability.

    Hurricane Sandy hit the eastern coast of the United States in October 2012, causing billions of dollars in damage and acute physical and mental health problems. The long-term mental health consequences of the storm and their predictors have not been studied. New York City and Long Island residents completed questionnaires regarding their initial Hurricane Sandy exposure and mental health symptoms at baseline and 1 year later (N = 130). There were statistically significant decreases in anxiety scores (mean difference = -0.33, p Hurricane Sandy has an impact on PTSD symptoms that persists over time. Given the likelihood of more frequent and intense hurricanes due to climate change, future hurricane recovery efforts must consider the long-term effects of hurricane exposure on mental health, especially on PTSD, when providing appropriate assistance and treatment.

  14. Rebuilding Emergency Care After Hurricane Sandy. (United States)

    Lee, David C; Smith, Silas W; McStay, Christopher M; Portelli, Ian; Goldfrank, Lewis R; Husk, Gregg; Shah, Nirav R


    A freestanding, 911-receiving emergency department was implemented at Bellevue Hospital Center during the recovery efforts after Hurricane Sandy to compensate for the increased volume experienced at nearby hospitals. Because inpatient services at several hospitals remained closed for months, emergency volume increased significantly. Thus, in collaboration with the New York State Department of Health and other partners, the Health and Hospitals Corporation and Bellevue Hospital Center opened a freestanding emergency department without on-site inpatient care. The successful operation of this facility hinged on key partnerships with emergency medical services and nearby hospitals. Also essential was the establishment of an emergency critical care ward and a system to monitor emergency department utilization at affected hospitals. The results of this experience, we believe, can provide a model for future efforts to rebuild emergency care capacity after a natural disaster such as Hurricane Sandy.

  15. Modeling hurricane effects on mangrove ecosystems (United States)

    Doyle, Thomas W.


    Mangrove ecosystems are at their most northern limit along the coastline of Florida and in isolated areas of the gulf coast in Louisiana and Texas. Mangroves are marine-based forests that have adapted to colonize and persist in salty intertidal waters. Three species of mangrove trees are common to the United States, black mangrove (Avicennia germinans), white mangrove (Laguncularia racemosa), and red mangrove (Rhizophora mangle). Mangroves are highly productive ecosystems and provide valuable habitat for fisheries and shorebirds. They are susceptible to lightning and hurricane disturbance, both of which occur frequently in south Florida. Climate change studies predict that, while these storms may not become more frequent, they may become more intense with warming sea temperatures. Sea-level rise alone has the potential for increasing the severity of storm surge, particularly in areas where coastal habitats and barrier shorelines are rapidly deteriorating. Given this possibility, U.S. Geological Survey researchers modeled the impact of hurricanes on south Florida mangrove communities.

    Energy Technology Data Exchange (ETDEWEB)

    Hartzman, P D


    An important goal in interactive computer graphics is to provide users with both quick system responses for basic graphics functions and enough computing power for complex calculations. One solution is to have a distributed graphics system in which a minicomputer and a powerful large computer share the work. The most versatile type of distributed system is an intelligent satellite system in which the minicomputer is programmable by the application user and can do most of the work while the large remote machine is used for difficult computations. At New York University, the hardware was configured from available equipment. The level of system intelligence resulted almost completely from software development. Unlike previous work with intelligent satellites, the resulting system had system control centered in the satellite. It also had the ability to reconfigure software during realtime operation. The design of the system was done at a very high level using set theoretic language. The specification clearly illustrated processor boundaries and interfaces. The high-level specification also produced a compact, machine-independent virtual graphics data structure for picture representation. The software was written in a systems implementation language; thus, only one set of programs was needed for both machines. A user can program both machines in a single language. Tests of the system with an application program indicate that is has very high potential. A major result of this work is the demonstration that a gigantic investment in new hardware is not necessary for computing facilities interested in graphics.

  18. Epidemic gasoline exposures following Hurricane Sandy. (United States)

    Kim, Hong K; Takematsu, Mai; Biary, Rana; Williams, Nicholas; Hoffman, Robert S; Smith, Silas W


    Major adverse climatic events (MACEs) in heavily-populated areas can inflict severe damage to infrastructure, disrupting essential municipal and commercial services. Compromised health care delivery systems and limited utilities such as electricity, heating, potable water, sanitation, and housing, place populations in disaster areas at risk of toxic exposures. Hurricane Sandy made landfall on October 29, 2012 and caused severe infrastructure damage in heavily-populated areas. The prolonged electrical outage and damage to oil refineries caused a gasoline shortage and rationing unseen in the USA since the 1970s. This study explored gasoline exposures and clinical outcomes in the aftermath of Hurricane Sandy. Prospectively collected, regional poison control center (PCC) data regarding gasoline exposure cases from October 29, 2012 (hurricane landfall) through November 28, 2012 were reviewed and compared to the previous four years. The trends of gasoline exposures, exposure type, severity of clinical outcome, and hospital referral rates were assessed. Two-hundred and eighty-three gasoline exposures were identified, representing an 18 to 283-fold increase over the previous four years. The leading exposure route was siphoning (53.4%). Men comprised 83.0% of exposures; 91.9% were older than 20 years of age. Of 273 home-based calls, 88.7% were managed on site. Asymptomatic exposures occurred in 61.5% of the cases. However, minor and moderate toxic effects occurred in 12.4% and 3.5% of cases, respectively. Gastrointestinal (24.4%) and pulmonary (8.4%) symptoms predominated. No major outcomes or deaths were reported. Hurricane Sandy significantly increased gasoline exposures. While the majority of exposures were managed at home with minimum clinical toxicity, some patients experienced more severe symptoms. Disaster plans should incorporate public health messaging and regional PCCs for public health promotion and toxicological surveillance.

  19. Performance of Oil Infrastructure during Hurricane Harvey (United States)

    Bernier, C.; Kameshwar, S.; Padgett, J.


    Three major refining centers - Corpus Christi, Houston, and Beaumont/Port Arthur - were affected during Hurricane Harvey. Damage to oil infrastructure, especially aboveground storage tanks (ASTs), caused the release of more than a million gallons of hazardous chemicals in the environment. The objective of this presentation is to identify and gain a better understanding of the different damage mechanisms that occurred during Harvey in order to avoid similar failures during future hurricane events. First, a qualitative description of the damage suffered by ASTs during Hurricane Harvey is presented. Analysis of aerial imagery and incident reports indicate that almost all spills were caused by rainfall and the associated flooding. The largest spill was caused by two large ASTs that floated due to flooding in the Houston Ship Channel releasing 500,000 gallons of gasoline. The vulnerability of ASTs subjected to flooding was already well known and documented from previous storm events. In addition to flooding, Harvey also exposed the vulnerability of ASTs with external floating roof to extreme rainfall; more than 15 floating roofs sank or tilted due to rain water accumulation on them, releasing pollutants in the atmosphere. Secondly, recent fragility models developed by the authors are presented which allow structural vulnerability assessment of floating roofs during rainfall events and ASTs during flood events. The fragility models are then coupled with Harvey rainfall and flood empirical data to identify the conditions (i.e.: internal liquid height or density, drainage system design and efficiency, etc.) that could have led to the observed failures during Hurricane Harvey. Finally, the conditions causing tank failures are studied to propose mitigation measures to prevent future AST failures during severe storm, flood, or rainfall events.

  20. Hurricane Katrina as a "teachable moment"

    Directory of Open Access Journals (Sweden)

    M. H. Glantz


    Full Text Available By American standards, New Orleans is a very old, very popular city in the southern part of the United States. It is located in Louisiana at the mouth of the Mississippi River, a river which drains about 40% of the Continental United States, making New Orleans a major port city. It is also located in an area of major oil reserves onshore, as well as offshore, in the Gulf of Mexico. Most people know New Orleans as a tourist hotspot; especially well-known is the Mardi Gras season at the beginning of Lent. People refer to the city as the "Big Easy". A recent biography of the city refers to it as the place where the emergence of modern tourism began. A multicultural city with a heavy French influence, it was part of the Louisiana Purchase from France in early 1803, when the United States bought it, doubling the size of the United States at that time.

    Today, in the year 2007, New Orleans is now known for the devastating impacts it withstood during the onslaught of Hurricane Katrina in late August 2005. Eighty percent of the city was submerged under flood waters. Almost two years have passed, and many individuals and government agencies are still coping with the hurricane's consequences. And insurance companies have been withdrawing their coverage for the region.

    The 2005 hurricane season set a record, in the sense that there were 28 named storms that calendar year. For the first time in hurricane forecast history, hurricane forecasters had to resort to the use of Greek letters to name tropical storms in the Atlantic and Gulf (Fig.~1.

    Hurricane Katrina was a Category 5 hurricane when it was in the middle of the Gulf of Mexico, after having passed across southern Florida. At landfall, Katrina's winds decreased in speed and it was relabeled as a Category 4. It devolved into a Category 3 hurricane as it passed inland when it did most of its damage. Large expanses of the city were inundated, many parts under water on

    By American standards, New Orleans is a very old, very popular city in the southern part of the United States. It is located in Louisiana at the mouth of the Mississippi River, a river which drains about 40% of the Continental United States, making New Orleans a major port city. It is also located in an area of major oil reserves onshore, as well as offshore, in the Gulf of Mexico. Most people know New Orleans as a tourist hotspot; especially well-known is the Mardi Gras season at the beginning of Lent. People refer to the city as the "Big Easy". A recent biography of the city refers to it as the place where the emergence of modern tourism began. A multicultural city with a heavy French influence, it was part of the Louisiana Purchase from France in early 1803, when the United States bought it, doubling the size of the United States at that time. Today, in the year 2007, New Orleans is now known for the devastating impacts it withstood during the onslaught of Hurricane Katrina in late August 2005. Eighty percent of the city was submerged under flood waters. Almost two years have passed, and many individuals and government agencies are still coping with the hurricane's consequences. And insurance companies have been withdrawing their coverage for the region. The 2005 hurricane season set a record, in the sense that there were 28 named storms that calendar year. For the first time in hurricane forecast history, hurricane forecasters had to resort to the use of Greek letters to name tropical storms in the Atlantic and Gulf (Fig.~1). Hurricane Katrina was a Category 5 hurricane when it was in the middle of the Gulf of Mexico, after having passed across southern Florida. At landfall, Katrina's winds decreased in speed and it was relabeled as a Category 4. It devolved into a Category 3 hurricane as it passed inland when it did most of its damage. Large expanses of the city were inundated, many parts under water on the order of 20 feet or so. The Ninth Ward, heavily

    Downward, J.G.


    The VAX Professional Workstation (VPW) is a collection of programs and procedures designed to provide an integrated work-station environment for the staff at KMS Fusion's research laboratories. During the past year numerous capabilities have been added to VPW, including support for VT125/VT240/4014 graphic workstations, editing windows, and additional desk utilities. Graphics workstation support allows users to create, edit, and modify graph data files, enter the data via a graphic tablet, create simple plots with DATATRIEVE or DECgraph on ReGIS terminals, or elaborate plots with TEKGRAPH on ReGIS or Tektronix terminals. Users may assign display error bars to the data and interactively plot it in a variety of ways. Users also can create and display viewgraphs. Hard copy output for a large network of office terminals is obtained by multiplexing each terminal's video output into a recently developed video multiplexer front ending a single channel video hard copy unit

    CERN Document Server

    Sakas, Georgios; Peitgen, Heinz-Otto; Englert, Gabriele


    Fractal geometry has become popular in the last 15 years, its applications can be found in technology, science, or even arts. Fractal methods and formalism are seen today as a general, abstract, but nevertheless practical instrument for the description of nature in a wide sense. But it was Computer Graphics which made possible the increasing popularity of fractals several years ago, and long after their mathematical formulation. The two disciplines are tightly linked. The book contains the scientificcontributions presented in an international workshop in the "Computer Graphics Center" in Darmstadt, Germany. The target of the workshop was to present the wide spectrum of interrelationships and interactions between Fractal Geometry and Computer Graphics. The topics vary from fundamentals and new theoretical results to various applications and systems development. All contributions are original, unpublished papers.The presentations have been discussed in two working groups; the discussion results, together with a...

  12. Jansenism in the Evaluation of the Graduates of the St. Petersburg Theological Academy: from Ivan Troitsky to St. Tikhon (Bellavin

    Directory of Open Access Journals (Sweden)

    Sukhova Nataliia


    Full Text Available The present study continues a series of publications exploring “augustiniana” within the Russian ecclesiastical scholarship, i.e. the work of professors and students of Theological academies devoted to Saint Augustine and conducted prior to the Russian Revolution. In this paper we switch our attention from the person and heritage of the bishop of Hippo to so called Augustinian movements of the 17th century and in particular to Jansenism. We predominantly focus on two texts: Magister’s thesis of an alumni of Saint-Petersburg Theological Academy Ivan Troitsky (1859 — a future professor of his Alma Mater, and a paper of his pupil Vasily Bellavin — in future the Most Holy Patriarch Tikhon. The latter document dates back to 1891 and is based on currently unavailable Candidate’s thesis of Vasiliy Bellavin (1888. Our analysis has shown that although the content of the two explored documents is out of date (now that 150 years have elapsed since they were written, their signifi cance for the history of theology is out of doubt. The questions posed by Jansenism turned out highly relevant for the church life in Russia in the late 1850s as well as in the late 1880s — early 1890s. Jansenists reflected upon church hierarchy and its authority, the “enigma of humanity”, actual and potential state of human nature, grace and freedom, the role Holy Scripture in the life of the Church and every christian, religious upbringing and education. Another factor that elevated interest to Jansenists’ movements of the 17th century during the second of the above mentioned periods was the preparation to a new stage of the dialog with the Old Catholics who had joined the followers of Jansenists, i.e. with the Church of Utrecht. Treating Jansenists’ thought with sympathy the young Russian theologians proved open to consider without bias all truth seeking attempts leading to Orthodox tradition. However in both cases our authors soberly realised that

  16. Storyboard dalam Pembuatan Motion Graphic

    Directory of Open Access Journals (Sweden)

    Satrya Mahardhika


    Full Text Available Motion graphics is one category in the animation that makes animation with lots of design elements in each component. Motion graphics needs long process including preproduction, production, and postproduction. Preproduction has an important role so that the next stage may provide guidance or instructions for the production process or the animation process. Preproduction includes research, making the story, script, screenplay, character, environment design and storyboards. The storyboard will be determined through camera angles, blocking, sets, and many supporting roles involved in a scene. Storyboard is also useful as a production reference in recording or taping each scene in sequence or as an efficient priority. The example used is an ad creation using motion graphic animation storyboard which has an important role as a blueprint for every scene and giving instructions to make the transition movement, layout, blocking, and defining camera movement that everything should be done periodically in animation production. Planning before making the animation or motion graphic will make the job more organized, presentable, and more efficient in the process.

  1. TEKLIB, Tektronix Graphics Subroutine Library

    International Nuclear Information System (INIS)

    Wolf, M.L.


    1 - Description of program or function: TEKLIB is a library of subroutines that produces graphical output on all Tektronix terminals with model numbers from 4010 through 4115. The application program identifies the model number in the initialization subroutine, GRSTRT, and then uses this number as a flag throughout the run to tailor the graphical output to that specific device. Output includes lines, markers, text, polygons, and panels. Graphic input is supported on all terminals. 2 - Method of solution: TEKLIB uses two coordinate systems, viewport and world, to generate graphic images on the screen. Viewport coordinates refer to an imaginary rectangular grid on the display screen surface. The world coordinate system is a rectangular grid on any x-y plane, defined by the application program. The rectangular portion of the x-y plane specified, termed a w indow , is projected onto a rectangular region of the screen, called a v iewport . In addition to 2-D graphics, TEKLIB also provides subroutines for drawing projections of 3-D objects. The application program first defines a point in space to look at the v iew point , and the direction and distance from that point to the observer's position. A viewing transformation is performed on each x,y,z point to project it onto a v iew plane , a plane perpendicular to the line of sight and passing through the view point. This view plane then becomes the x-y plane of the world window which is mapped into the viewport. 3 - Restrictions on the complexity of the problem: TEKLIB does not attempt to emulate attributes such as line style and marker type in software if the terminal does not support those attributes in hardware

  2. Predicting hurricane wind damage by claim payout based on Hurricane Ike in Texas

    Directory of Open Access Journals (Sweden)

    Ji-Myong Kim


    Full Text Available The increasing occurrence of natural disasters and their related damage have led to a growing demand for models that predict financial loss. Although considerable research on the financial losses related to natural disasters has found significant predictors, there has been a lack of comprehensive study that addresses the relationship among vulnerabilities, natural disasters, and the economic losses of individual buildings. This study identifies the vulnerability indicators for hurricanes to establish a metric to predict the related financial loss. We classify hurricane-prone areas by highlighting the spatial distribution of losses and vulnerabilities. This study used a Geographical Information System (GIS to combine and produce spatial data and a multiple regression method to establish a wind damage prediction model. As the dependent variable, we used the value of the Texas Windstorm Insurance Association (TWIA claim payout divided by the appraised values of the buildings to predict real economic loss. As independent variables, we selected a hurricane indicator and built environment vulnerability indicators. The model we developed can be used by government agencies and insurance companies to predict hurricane wind damage.

  6. Physical aspects of Hurricane Hugo in Puerto Rico (United States)

    Scatena, F.N.; Larsen, Matthew C.


    On 18 September 1989 the western part ofHurricane Hugo crossed eastern Puerto Rico and the Luquillo Experimental Forest (LEF). Storm-facing slopes on the northeastern part of the island that were within 15 km of the eye and received greater than 200 mm of rain were most affected by the storm. In the LEF and nearby area, recurrence intervals associated with Hurricane Hugo were 50 yr for wind velocity, 10 to 31 yr for stream discharge, and 5 yr for rainfall intensity. To compare the magnitudes of the six hurricanes to pass over PuertoRico since 1899, 3 indices were developed using the standardized values of the product of: the maximum sustained wind speed at San Juan squared and storm duration; the square of the product of the maximum sustained wind velocity at San Juan and the ratio of the distance between the hurricane eye and San Juan to the distance between the eye and percentage of average annual rainfall delivered by the storm. Based on these indices, HurricaneHugo was of moderate intensity. However, because of the path of Hurricane Hugo, only one of these six storms (the 1932 storm) caused more damage to the LEF than Hurricane Hugo. Hurricanes of Hugo's magnitude are estimated to pass over the LEF once every 50-60 yr, on average.

    Full Text Available Technological innovation in the video games industry is a rich area of research that has barely been explored as of yet. Gamers are always clamoring for novelty and a remedy to the oft-decried “sequelitis” that “plagues” the industry, while game publishers and platform holders secretly plan a next-gen platform to capture the ever-shifting market. In this light, the importance of graphics cannot be understated, as it is usually taken for granted in game historiography that “[g]ame graphics were, and to a large extent still are, the main criteria by which advancing video game technology is benchmarked” (Wolf, 2003, p.53.

  17. Hurricane Sandy: Shared Trauma and Therapist Self-Disclosure. (United States)

    Rao, Nyapati; Mehra, Ashwin


    Hurricane Sandy was one of the most devastating storms to hit the United States in history. The impact of the hurricane included power outages, flooding in the New York City subway system and East River tunnels, disrupted communications, acute shortages of gasoline and food, and a death toll of 113 people. In addition, thousands of residences and businesses in New Jersey and New York were destroyed. This article chronicles the first author's personal and professional experiences as a survivor of the hurricane, more specifically in the dual roles of provider and trauma victim, involving informed self-disclosure with a patient who was also a victim of the hurricane. The general analytic framework of therapy is evaluated in the context of the shared trauma faced by patient and provider alike in the face of the hurricane, leading to important implications for future work on resilience and recovery for both the therapist and patient.

  18. On the Impact Angle of Hurricane Sandy's New Jersey Landfall (United States)

    Hall, Timothy M.; Sobel, Adam H.


    Hurricane Sandy's track crossed the New Jersey coastline at an angle closer to perpendicular than any previous hurricane in the historic record, one of the factors contributing to recordsetting peak-water levels in parts of New Jersey and New York. To estimate the occurrence rate of Sandy-like tracks, we use a stochastic model built on historical hurricane data from the entire North Atlantic to generate a large sample of synthetic hurricanes. From this synthetic set we calculate that under long-term average climate conditions, a hurricane of Sandy's intensity or greater (category 1+) makes NJ landfall at an angle at least as close to perpendicular as Sandy's at an average annual rate of 0.0014 yr-1 (95% confidence range 0.0007 to 0.0023); i.e., a return period of 714 years (95% confidence range 435 to 1429).

  19. Shelf sediment transport during hurricanes Katrina and Rita (United States)

    Xu, Kehui; Mickey, Rangley C.; Chen, Qin; Harris, Courtney K.; Hetland, Robert D.; Hu, Kelin; Wang, Jiaze


    Hurricanes can greatly modify the sedimentary record, but our coastal scientific community has rather limited capability to predict hurricane-induced sediment deposition. A three-dimensional sediment transport model was developed in the Regional Ocean Modeling System (ROMS) to study seabed erosion and deposition on the Louisiana shelf in response to Hurricanes Katrina and Rita in the year 2005. Sensitivity tests were performed on both erosional and depositional processes for a wide range of erosional rates and settling velocities, and uncertainty analysis was done on critical shear stresses using the polynomial chaos approximation method. A total of 22 model runs were performed in sensitivity and uncertainty tests. Estimated maximum erosional depths were sensitive to the inputs, but horizontal erosional patterns seemed to be controlled mainly by hurricane tracks, wave-current combined shear stresses, seabed grain sizes, and shelf bathymetry. During the passage of two hurricanes, local resuspension and deposition dominated the sediment transport mechanisms. Hurricane Katrina followed a shelf-perpendicular track before making landfall and its energy dissipated rapidly within about 48 h along the eastern Louisiana coast. In contrast, Hurricane Rita followed a more shelf-oblique track and disturbed the seabed extensively during its 84-h passage from the Alabama-Mississippi border to the Louisiana-Texas border. Conditions to either side of Hurricane Rita's storm track differed substantially, with the region to the east having stronger winds, taller waves and thus deeper erosions. This study indicated that major hurricanes can disturb the shelf at centimeter to meter levels. Each of these two hurricanes suspended seabed sediment mass that far exceeded the annual sediment inputs from the Mississippi and Atchafalaya Rivers, but the net transport from shelves to estuaries is yet to be determined. Future studies should focus on the modeling of sediment exchange between

  5. Learning Graphical Models With Hubs. (United States)

    Tan, Kean Ming; London, Palma; Mohan, Karthik; Lee, Su-In; Fazel, Maryam; Witten, Daniela


    We consider the problem of learning a high-dimensional graphical model in which there are a few hub nodes that are densely-connected to many other nodes. Many authors have studied the use of an ℓ 1 penalty in order to learn a sparse graph in the high-dimensional setting. However, the ℓ 1 penalty implicitly assumes that each edge is equally likely and independent of all other edges. We propose a general framework to accommodate more realistic networks with hub nodes, using a convex formulation that involves a row-column overlap norm penalty. We apply this general framework to three widely-used probabilistic graphical models: the Gaussian graphical model, the covariance graph model, and the binary Ising model. An alternating direction method of multipliers algorithm is used to solve the corresponding convex optimization problems. On synthetic data, we demonstrate that our proposed framework outperforms competitors that do not explicitly model hub nodes. We illustrate our proposal on a webpage data set and a gene expression data set.

  6. Graphical Classification of Entangled Qutrits

    Directory of Open Access Journals (Sweden)

    Kentaro Honda


    Full Text Available A multipartite quantum state is entangled if it is not separable. Quantum entanglement plays a fundamental role in many applications of quantum information theory, such as quantum teleportation. Stochastic local quantum operations and classical communication (SLOCC cannot essentially change quantum entanglement without destroying it. Therefore, entanglement can be classified by dividing quantum states into equivalence classes, where two states are equivalent if each can be converted into the other by SLOCC. Properties of this classification, especially in the case of non two-dimensional quantum systems, have not been well studied. Graphical representation is sometimes used to clarify the nature and structural features of entangled states. SLOCC equivalence of quantum bits (qubits has been described graphically via a connection between tripartite entangled qubit states and commutative Frobenius algebras (CFAs in monoidal categories. In this paper, we extend this method to qutrits, i.e., systems that have three basis states. We examine the correspondence between CFAs and tripartite entangled qutrits. Using the symmetry property, which is required by the definition of a CFA, we find that there are only three equivalence classes that correspond to CFAs. We represent qutrits graphically, using the connection to CFAs. We derive equations that characterize the three equivalence classes. Moreover, we show that any qutrit can be represented as a composite of three graphs that correspond to the three classes.

  7. TEK11 graphics user's guide

    International Nuclear Information System (INIS)

    Stewart, C.R. Jr.; Joubert, W.D.; Overbey, D.R.; Stewart, K.A.


    The TEK11 graphics library was written for use on PDP-11 minicomputers running the RT-11 operating system to drive Tektronix 4010 graphics display terminals. Library subroutines are coded in FORTRAN and assembly language. The library includes routines to draw axes, either linear or semilog, to plot data in terms of logical values without first scaling to screen coordinates, to label graphs, and to plot in a maximum of four regions on the screen. Modes of plotting may be point plot with any character at the point, vector plot, or bar plot. Two features, automatic scaling and windowing, permit the researcher to use computer graphics without spending time first to learn about scaling or ''Tek points'' and preparing long parameter lists for subroutines. Regions on the screen are defined by specifying minima and maxima logical coordinates, i.e., 0 K or milliseconds, and a region number. After definition, a region may be activated for plotting by calling REGN with the region number as an argument

  8. Graphical Language for Data Processing (United States)

    Alphonso, Keith


    A graphical language for processing data allows processing elements to be connected with virtual wires that represent data flows between processing modules. The processing of complex data, such as lidar data, requires many different algorithms to be applied. The purpose of this innovation is to automate the processing of complex data, such as LIDAR, without the need for complex scripting and programming languages. The system consists of a set of user-interface components that allow the user to drag and drop various algorithmic and processing components onto a process graph. By working graphically, the user can completely visualize the process flow and create complex diagrams. This innovation supports the nesting of graphs, such that a graph can be included in another graph as a single step for processing. In addition to the user interface components, the system includes a set of .NET classes that represent the graph internally. These classes provide the internal system representation of the graphical user interface. The system includes a graph execution component that reads the internal representation of the graph (as described above) and executes that graph. The execution of the graph follows the interpreted model of execution in that each node is traversed and executed from the original internal representation. In addition, there are components that allow external code elements, such as algorithms, to be easily integrated into the system, thus making the system infinitely expandable.

    Directory of Open Access Journals (Sweden)

    Jan Benacka


    Full Text Available In the article, the formulas for orthographic parallel projection of 3D bodies on computer screen are derived using secondary school vector algebra. The spreadsheet implementation is demonstrated in six applications that project bodies with increasing intricacy – a convex body (cube with non-solved visibility, convex bodies (cube, chapel with solved visibility, a coloured convex body (chapel with solved visibility, and a coloured non-convex body (church with solved visibility. The projections are revolvable in horizontal and vertical plane, and they are changeable in size. The examples show an unusual way of using spreadsheets as a 3D computer graphics tool. The applications can serve as a simple introduction to the general principles of computer graphics, to the graphics with spreadsheets, and as a tool for exercising stereoscopic vision. The presented approach is usable at visualising 3D scenes within some topics of secondary school curricula as solid geometry (angles and distances of lines and planes within simple bodies or analytic geometry in space (angles and distances of lines and planes in E3, and even at university level within calculus at visualising graphs of z = f(x,y functions. Examples are pictured.

  15. Estimating hurricane hazards using a GIS system

    Directory of Open Access Journals (Sweden)

    A. Taramelli


    Full Text Available This paper develops a GIS-based integrated approach to the Multi-Hazard model method, with reference to hurricanes. This approach has three components: data integration, hazard assessment and score calculation to estimate elements at risk such as affected area and affected population. First, spatial data integration issues within a GIS environment, such as geographical scales and data models, are addressed. Particularly, the integration of physical parameters and population data is achieved linking remotely sensed data with a high resolution population distribution in GIS. In order to assess the number of affected people, involving heterogeneous data sources, the selection of spatial analysis units is basic. Second, specific multi-hazard tasks, such as hazard behaviour simulation and elements at risk assessment, are composed in order to understand complex hazard and provide support for decision making. Finally, the paper concludes that the integrated approach herein presented can be used to assist emergency management of hurricane consequences, in theory and in practice.

  16. A Simulation Tool for Hurricane Evacuation Planning

    Directory of Open Access Journals (Sweden)

    Daniel J. Fonseca


    Full Text Available Atlantic hurricanes and severe tropical storms are a serious threat for the communities in the Gulf of Mexico region. Such storms are violent and destructive. In response to these dangers, coastal evacuation may be ordered. This paper describes the development of a simulation model to analyze the movement of vehicles through I-65, a major US Interstate highway that runs north off the coastal City of Mobile, Alabama, towards the State of Tennessee, during a massive evacuation originated by a disastrous event such a hurricane. The constructed simulation platform consists of a primary and two secondary models. The primary model is based on the entry of vehicles from the 20 on-ramps to I-65. The two secondary models assist the primary model with related traffic events such as car breakdowns and accidents, traffic control measures, interarrival signaling, and unforeseen emergency incidents, among others. Statistical testing was performed on the data generated by the simulation model to indentify variation in relevant traffic variables affecting the timely flow of vehicles travelling north. The performed statistical analysis focused on the closing of alternative on-ramps throughout the Interstate.

  17. Weathering the storm: hurricanes and birth outcomes. (United States)

    Currie, Janet; Rossin-Slater, Maya


    A growing literature suggests that stressful events in pregnancy can have negative effects on birth outcomes. Some of the estimates in this literature may be affected by small samples, omitted variables, endogenous mobility in response to disasters, and errors in the measurement of gestation, as well as by a mechanical correlation between longer gestation and the probability of having been exposed. We use millions of individual birth records to examine the effects of exposure to hurricanes during pregnancy, and the sensitivity of the estimates to these econometric problems. We find that exposure to a hurricane during pregnancy increases the probability of abnormal conditions of the newborn such as being on a ventilator more than 30min and meconium aspiration syndrome (MAS). Although we are able to reproduce previous estimates of effects on birth weight and gestation, our results suggest that measured effects of stressful events on these outcomes are sensitive to specification and it is preferable to use more sensitive indicators of newborn health.

  18. Hurricane Sandy science plan: coastal impact assessments (United States)

    Stronko, Jakob M.


    Hurricane Sandy devastated some of the most heavily populated eastern coastal areas of the Nation. With a storm surge peaking at more than 19 feet, the powerful landscape-altering destruction of Hurricane Sandy is a stark reminder of why the Nation must become more resilient to coastal hazards. In response to this natural disaster, the U.S. Geological Survey (USGS) received a total of $41.2 million in supplemental appropriations from the Department of the Interior (DOI) to support response, recovery, and rebuilding efforts. These funds support a science plan that will provide critical scientific information necessary to inform management decisions for recovery of coastal communities, and aid in preparation for future natural hazards. This science plan is designed to coordinate continuing USGS activities with stakeholders and other agencies to improve data collection and analysis that will guide recovery and restoration efforts. The science plan is split into five distinct themes: coastal topography and bathymetry, impacts to coastal beaches and barriers, impacts of storm surge, including disturbed estuarine and bay hydrology, impacts on environmental quality and persisting contaminant exposures, impacts to coastal ecosystems, habitats, and fish and wildlife. This fact sheet focuses assessing impacts to coastal beaches and barriers.

  8. Geologic record of Hurricane impacts on the New Jersey coast (United States)

    Nikitina, Daria; Horton, Benjamin; Khan, Nicole; Clear, Jennifer; Shaw, Timothy; Enache, Mihaela; Frizzera, Dorina; Procopio, Nick; Potapova, Marina


    Hurricanes along the US Atlantic coast have caused significant damage and loss of human life over the last century. Recent studies suggest that intense-hurricane activity is closely related to changes of sea surface temperatures and therefore the risk of hurricane strikes may increase in the future. A clear understanding of the role of recent warming on tropical cyclone activity is limited by the shortness of the instrumental record. However, the sediment preserved beneath coastal wetlands is an archive of when hurricanes impacted the coast. We present two complimenting approaches that help to extend pre-historic record and assess frequency and intensity of hurricane landfalls along the New Jersey cost; dating overwash deposits and hurricane-induced salt-marsh erosion documented at multiple sites. The stratigraphic investigation of estuarine salt marshes in the southern New Jersey documented seven distinctive erosion events that correlate among different sites. Radiocarbon dates suggest the prehistoric events occurred in AD 558-673, AD 429-966, AD 558-673, Ad 1278-1438, AD 1526-1558 or AD 1630-1643 (Nikitina et al., 2014). Younger sequences correspond with historical land-falling hurricanes in AD 1903 and AD 1821 or AD 1788. Four events correlate well with barrier overwash deposits documented along the New Jersey coast (Donnelley et al., 2001 and 2004). The stratigraphic sequence of salt High resolution sedimentary-based reconstructions of past intense-hurricane landfalls indicate that significant variability in the frequency of intense hurricanes occurred over the last 2000 years.

    Hurricanes occur over much of the U.S. Atlantic and Gulf coasts, from Long Island to the U.S.-Mexico border, encompassing much of the nation's primary offshore wind resource. Category 5 hurricanes have made landfall as far north as North Carolina, with Category 3 hurricanes reaching New York with some frequency. Along the US West coast, typhoons strike with similar frequency and severity. At present, offshore wind turbine design practices do not fully consider the severe operating conditions imposed by hurricanes. Although universally applied to most turbine designs, International Electrotechnical Commission (IEC) standards do not sufficiently address the duration, directionality, magnitude, or character of hurricanes. To assess advanced design features that could mitigate hurricane loading in various ways, this Hurricane-Resilient Wind Plant Concept Study considered a concept design study of a 500-megawatt (MW) wind power plant consisting of 10-MW wind turbines deployed in 25-meter (m) water depths in the Western Gulf of Mexico. This location was selected because hurricane frequency and severity provided a unique set of design challenges that would enable assessment of hurricane risk and projection of cost of energy (COE) changes, all in response to specific U.S. Department of Energy (DOE) objectives. Notably, the concept study pursued a holistic approach that incorporated multiple advanced system elements at the wind turbine and wind power plant levels to meet objectives for system performance and reduced COE. Principal turbine system elements included a 10-MW rotor with structurally efficient, low-solidity blades; a lightweight, permanent-magnet, direct-drive generator, and an innovative fixed substructure. At the wind power plant level, turbines were arrayed in a large-scale wind power plant in a manner aimed at balancing energy production against capital, installation, and operation and maintenance (O&M) costs to achieve significant overall reductions in

    Stefan Skiba


    Full Text Available The production requirements of original graphic works of art have changed since 1980. The development of digital printing using lightfast colors now rivals traditional techniques such as wood cut, screen print, lithography, etching etc. Today, with respect to artistic legitimacy, original graphics using traditional printing techniques compete with original graphics produced by digital printing techniques on the art market. What criteria distinguish traditional printing techniques from those of digital printing in the production and acquisition of original graphics? What consequences is the serious artist faced with when deciding to implement digital print production? How does digital print change original graphic acquisition decisions?

Instead of synthesizing a complex signal when needed, the signal is synthesized beforehand over a small set of Wang tiles or corner tiles. Arbitrary large amounts of that signal can then efficiently be generated when needed by generating a stochastic tiling, and storing only a small set of tiles reduces storage requirements.

  18. Hurricane Isabel gives accelerators a severe test

    International Nuclear Information System (INIS)

    Swapan Chattopadhyay


    Hurricane Isabel was at category five--the most violent on the Saffir-Simpson scale of hurricane strength--when it began threatening the central Atlantic seaboard of the US. Over the course of several days, precautions against the extreme weather conditions were taken across the Jefferson Lab site in south-east Virginia. On 18 September 2003, when Isabel struck North Carolina's Outer Banks and moved northward, directly across the region around the laboratory, the storm was still quite destructive, albeit considerably reduced in strength. The flood surge and trees felled by wind substantially damaged or even devastated buildings and homes, including many belonging to Jefferson Lab staff members. For the laboratory itself, Isabel delivered an unplanned and severe challenge in another form: a power outage that lasted nearly three-and-a-half days, and which severely tested the robustness of Jefferson Lab's two superconducting machines, the Continuous Electron Beam Accelerator Facility (CEBAF) and the superconducting radiofrequency ''driver'' accelerator of the laboratory's free-electron laser. Robustness matters greatly for science at a time when microwave superconducting linear accelerators (linacs) are not only being considered, but in some cases already being built for projects such as neutron sources, rare-isotope accelerators, innovative light sources and TeV-scale electron-positron linear colliders. Hurricane Isabel interrupted a several-week-long maintenance shutdown of CEBAF, which serves nuclear and particle physics and represents the world's pioneering large-scale implementation of superconducting radiofrequency (SRF) technology. The racetrack-shaped machine is actually a pair of 500-600 MeV SRF linacs interconnected by recirculation arc beamlines. CEBAF delivers simultaneous beams at up to 6 GeV to three experimental halls. An imminent upgrade will double the energy to 12 GeV and add an extra hall for ''quark confinement'' studies. On a smaller scale

  19. Hurricane impacts on a pair of coastal forested watersheds: implications of selective hurricane damage to forest structure and streamflow dynamics (United States)

    Jayakaran, A. D.; Williams, T. M.; Ssegane, H.; Amatya, D. M.; Song, B.; Trettin, C. C.


    Hurricanes are infrequent but influential disruptors of ecosystem processes in the southeastern Atlantic and Gulf coasts. Every southeastern forested wetland has the potential to be struck by a tropical cyclone. We examined the impact of Hurricane Hugo on two paired coastal South Carolina watersheds in terms of streamflow and vegetation dynamics, both before and after the hurricane's passage in 1989. The study objectives were to quantify the magnitude and timing of changes including a reversal in relative streamflow difference between two paired watersheds, and to examine the selective impacts of a hurricane on the vegetative composition of the forest. We related these impacts to their potential contribution to change watershed hydrology through altered evapotranspiration processes. Using over 30 years of monthly rainfall and streamflow data we showed that there was a significant transformation in the hydrologic character of the two watersheds - a transformation that occurred soon after the hurricane's passage. We linked the change in the rainfall-runoff relationship to a catastrophic change in forest vegetation due to selective hurricane damage. While both watersheds were located in the path of the hurricane, extant forest structure varied between the two watersheds as a function of experimental forest management techniques on the treatment watershed. We showed that the primary damage was to older pines, and to some extent larger hardwood trees. We believe that lowered vegetative water use impacted both watersheds with increased outflows on both watersheds due to loss of trees following hurricane impact. However, one watershed was able to recover to pre hurricane levels of evapotranspiration at a quicker rate due to the greater abundance of pine seedlings and saplings in that watershed.

  1. Genesis and maintenance of "Mediterranean hurricanes"

    Directory of Open Access Journals (Sweden)

    K. Emanuel


    Full Text Available Cyclonic storms that closely resemble tropical cyclones in satellite images occasionally form over the Mediterranean Sea. Synoptic and mesoscale analyses of such storms show small, warm-core structure and surface winds sometimes exceeding 25ms-1 over small areas. These analyses, together with numerical simulations, reveal that in their mature stages, such storms intensify and are maintained by a feedback between surface enthalpy fluxes and wind, and as such are isomorphic with tropical cyclones. In this paper, I demonstrate that a cold, upper low over the Mediterranean can produce strong cyclogenesis in an axisymmetric model, thereby showing that baroclinic instability is not necessary during the mature stages of Mediterranean hurricanes.

  2. Identification of computer graphics objects

    Directory of Open Access Journals (Sweden)

    Rossinskyi Yu.M.


    Full Text Available The article is devoted to the use of computer graphics methods in problems of creating drawings, charts, drafting, etc. The widespread use of these methods requires the development of efficient algorithms for the identification of objects of drawings. The article analyzes the model-making algorithms for this problem and considered the possibility of reducing the time using graphics editing operations. Editing results in such operations as copying, moving and deleting objects specified images. These operations allow the use of a reliable identification of images of objects methods. For information on the composition of the image of the object along with information about the identity and the color should include information about the spatial location and other characteristics of the object (the thickness and style of contour lines, fill style, and so on. In order to enable the pixel image analysis to structure the information it is necessary to enable the initial code image objects color. The article shows the results of the implementation of the algorithm of encoding object identifiers. To simplify the process of building drawings of any kind, and reduce time-consuming, method of drawing objects identification is proposed based on the use as the ID information of the object color.

  11. Nurses respond to Hurricane Hugo victims' disaster stress. (United States)

    Weinrich, S; Hardin, S B; Johnson, M


    Hugo, a class IV hurricane, hit South Carolina September 22, 1989, and left behind a wake of terror and destruction. Sixty-one nursing students and five faculty were involved in disaster relief with families devastated by the hurricane. A review of the literature led these authors to propose a formulation of the concept of disaster stress, a synthesis of theories that explains response to disaster as a crisis response, a stress response, or as posttraumatic stress. With the concept of disaster stress serving as a theoretical foundation, the nurses observed, assessed, and intervened with one population of hurricane Hugo victims, noting their immediate psychosocial reactions and coping mechanisms. Victims' reactions to disaster stress included confusion, irritability, lethargy, withdrawal, and crying. The most frequently observed coping strategy of these hurricane Hugo victims was talking about their experiences; other coping tactics involved humor, religion, and altruism.

  13. Hurricane Sandy, Disaster Preparedness, and the Recovery Model. (United States)

    Pizzi, Michael A


    Hurricane Sandy was the second largest and costliest hurricane in U.S. history to affect multiple states and communities. This article describes the lived experiences of 24 occupational therapy students who lived through Hurricane Sandy using the Recovery Model to frame the research. Occupational therapy student narratives were collected and analyzed using qualitative methods and framed by the Recovery Model. Directed content and thematic analysis was performed using the 10 components of the Recovery Model. The 10 components of the Recovery Model were experienced by or had an impact on the occupational therapy students as they coped and recovered in the aftermath of the natural disaster. This study provides insight into the lived experiences and recovery perspectives of occupational therapy students who experienced Hurricane Sandy. Further research is indicated in applying the Recovery Model to people who survive disasters. Copyright © 2015 by the American Occupational Therapy Association, Inc.

  14. A team approach to preparing for hurricanes and other disasters. (United States)

    Sarmiento, Daniel; Barr, Jordan; Engel, Vic; Fuentes, Jose D.; Smith, Thomas J.; Zieman, Jay C.


    On October 24th, 2005, Hurricane Wilma made landfall on the south western shore of the Florida peninsula. This major disturbance destroyed approximately 30 percent of the mangrove forests in the area. However, the damage to the ecosystem following the hurricane provided researchers at the Florida Coastal Everglades (FCE) LTER site with the rare opportunity to track the recovery process of the mangroves as determined by carbon dioxide (CO2) and energy exchanges, measured along daily and seasonal time scales.

  17. Graphical programming at Sandia National Laboratories

    International Nuclear Information System (INIS)

    McDonald, M.J.; Palmquist, R.D.; Desjarlais, L.


    Sandia has developed an advanced operational control system approach, called Graphical Programming, to design, program, and operate robotic systems. The Graphical Programming approach produces robot systems that are faster to develop and use, safer in operation, and cheaper overall than altemative teleoperation or autonomous robot control systems. Graphical Programming also provides an efficient and easy-to-use interface to traditional robot systems for use in setup and programming tasks. This paper provides an overview of the Graphical Programming approach and lists key features of Graphical Programming systems. Graphical Programming uses 3-D visualization and simulation software with intuitive operator interfaces for the programming and control of complex robotic systems. Graphical Programming Supervisor software modules allow an operator to command and simulate complex tasks in a graphic preview mode and, when acceptable, command the actual robots and monitor their motions with the graphic system. Graphical Programming Supervisors maintain registration with the real world and allow the robot to perform tasks that cannot be accurately represented with models alone by using a combination of model and sensor-based control

  18. Hurricane Impact on Seepage Water in Larga Cave, Puerto Rico (United States)

    Vieten, Rolf; Warken, Sophie; Winter, Amos; Schröder-Ritzrau, Andrea; Scholz, Denis; Spötl, Christoph


    Hurricane-induced rainfall over Puerto Rico has characteristic δ18O values which are more negative than local rainfall events. Thus, hurricanes may be recorded in speleothems from Larga cave, Puerto Rico, as characteristic oxygen isotope excursions. Samples of 84 local rainfall events between 2012 and 2013 ranged from -6.2 to +0.3‰, whereas nine rainfall samples belonging to a rainband of hurricane Isaac (23-24 August 2012) ranged from -11.8 to -7.1‰. Cave monitoring covered the hurricane season of 2014 and investigated the impact of hurricane rainfall on drip water chemistry. δ18O values were measured in cumulative monthly rainwater samples above the cave. Inside the cave, δ18O values of instantaneous drip water samples were analyzed and drip rates were recorded at six drip sites. Most effective recharge appears to occur during the wet months (April-May and August-November). δ18O values of instantaneous drip water samples ranged from -3.5 to -2.4‰. In April 2014 and April 2015 some drip sites showed more negative δ18O values than the effective rainfall (-2.9‰), implying an influence of hurricane rainfall reaching the cave via stratified seepage flow months to years after the event. Speleothems from these drip sites in Larga cave have a high potential for paleotempestology studies.

  19. Oceanic control of Northeast Pacific hurricane activity at interannual timescales

    International Nuclear Information System (INIS)

    Balaguru, Karthik; Ruby Leung, L; Yoon, Jin-ho


    Sea surface temperature (SST) is not the only oceanic parameter that can play a key role in the interannual variability of Northeast Pacific hurricane activity. Using several observational data sets and the statistical technique of multiple linear regression analysis, we show that, along with SST, the thermocline depth (TD) plays an important role in hurricane activity at interannual timescales in this basin. Based on the parameter that dominates, the ocean basin can be divided into two sub-regions. In the Southern sub-region, which includes the hurricane main development area, interannual variability of the upper-ocean heat content (OHC) is primarily controlled by TD variations. Consequently, the interannual variability in the hurricane power dissipation index (PDI), which is a measure of the intensity of hurricane activity, is driven by that of the TD. On the other hand, in the Northern sub-region, SST exerts the major control over the OHC variability and, in turn, the PDI. Our study suggests that both SST and TD have a significant influence on the Northeast Pacific hurricane activity at interannual timescales and that their respective roles are more clearly delineated when sub-regions along an approximate north–south demarcation are considered rather than the basin as a whole.

  20. High Resolution Modeling of Hurricanes in a Climate Context (United States)

    Knutson, T. R.


    Modeling of tropical cyclone activity in a climate context initially focused on simulation of relatively weak tropical storm-like disturbances as resolved by coarse grid (200 km) global models. As computing power has increased, multi-year simulations with global models of grid spacing 20-30 km have become feasible. Increased resolution also allowed for simulation storms of increasing intensity, and some global models generate storms of hurricane strength, depending on their resolution and other factors, although detailed hurricane structure is not simulated realistically. Results from some recent high resolution global model studies are reviewed. An alternative for hurricane simulation is regional downscaling. An early approach was to embed an operational (GFDL) hurricane prediction model within a global model solution, either for 5-day case studies of particular model storm cases, or for "idealized experiments" where an initial vortex is inserted into an idealized environments derived from global model statistics. Using this approach, hurricanes up to category five intensity can be simulated, owing to the model's relatively high resolution (9 km grid) and refined physics. Variants on this approach have been used to provide modeling support for theoretical predictions that greenhouse warming will increase the maximum intensities of hurricanes. These modeling studies also simulate increased hurricane rainfall rates in a warmer climate. The studies do not address hurricane frequency issues, and vertical shear is neglected in the idealized studies. A recent development is the use of regional model dynamical downscaling for extended (e.g., season-length) integrations of hurricane activity. In a study for the Atlantic basin, a non-hydrostatic model with grid spacing of 18km is run without convective parameterization, but with internal spectral nudging toward observed large-scale (basin wavenumbers 0-2) atmospheric conditions from reanalyses. Using this approach, our

  1. Analyzing after-action reports from Hurricanes Andrew and Katrina: repeated, modified, and newly created recommendations. (United States)

    Knox, Claire Connolly


    Thirteen years after Hurricane Andrew struck Homestead, FL, Hurricane Katrina devastated the Gulf Coast of Mississippi, Alabama, and southeastern Louisiana. Along with all its destruction, the term "catastrophic" was redefined. This article extends the literature on these hurricanes by providing a macrolevel analysis of The Governor's Disaster Planning and Response Review Committee Final Report from Hurricane Andrew and three federal after-action reports from Hurricane Katrina, as well as a cursory review of relevant literature. Results provide evidence that previous lessons have not been learned or institutionalized with many recommendations being repeated or modified. This article concludes with a discussion of these lessons, as well as new issues arising during Hurricane Katrina.

  2. Spectra processing with computer graphics

    International Nuclear Information System (INIS)

    Kruse, H.


    A program of processng gamma-ray spectra in rock analysis is described. The peak search was performed by applying a cross-correlation function. The experimental data were approximated by an analytical function represented by the sum of a polynomial and a multiple peak function. The latter is Gaussian, joined with the low-energy side by an exponential. A modified Gauss-Newton algorithm is applied for the purpose of fitting the data to the function. The processing of the values derived from a lunar sample demonstrates the effect of different choices of polynomial orders for approximating the background for various fitting intervals. Observations on applications of interactive graphics are presented. 3 figures, 1 table

  3. The HEASARC graphical user interface (United States)

    White, N.; Barrett, P.; Jacobs, P.; Oneel, B.


    An OSF/Motif-based graphical user interface has been developed to facilitate the use of the database and data analysis software packages available from the High Energy Astrophysics Science Archive Research Center (HEASARC). It can also be used as an interface to other, similar, routines. A small number of tables are constructed to specify the possible commands and command parameters for a given set of analysis routines. These tables can be modified by a designer to affect the appearance of the interface screens. They can also be dynamically changed in response to parameter adjustments made while the underlying program is running. Additionally, a communication protocol has been designed so that the interface can operate locally or across a network. It is intended that this software be able to run on a variety of workstations and X terminals.

  7. Controlling a hurricane by altering its internal climate (United States)

    Mardhekar, D.


    Atmospheric hazards, like the fury of a hurricane, can be controlled by altering its internal climate. The hurricane controlling technique suggested is eco-friendly, compatible with hurricane size, has a sound scientific base and is practically possible. The key factor is a large scale dilution of the hurricane fuel, vapour, in the eye wall and spiral rain bands where condensation causing vapor volume reduction (a new concept which can be explained by Avogadro's law) and latent heat release drive the storm. This can be achieved by installing multiple storage tanks containing dry liquefied air on the onshore and offshore coastal regions and islands, preferably underground, in the usual path of a hurricane. Each storage tank is designed to hold and release dry liquefied air of around 100,000 tons. Satellite tracking of hurricanes can locate the eye wall and the spiral rain bands. The installed storage tanks coming under these areas will rapidly inject dry air in huge quantities thereby diluting the vapour content of the vapour-rich air in the eye wall and in the spiral rain bands. This will result in reduced natural input of vapour-rich air, reduced release of latent heat, reduced formation of the low pressure zone due to condensation and volume reduction of the vapor, expansion of the artificially introduced dry air as it goes up occupying a larger space with the diluted fuel, absorption of energy from the system by low temperature of the artificially introduced air. It will effect considerable condensation of the vapor near the sea surface thus further starving the hurricane of its fuel in its engine. Seeding materials, or microscopic dust as suggested by Dr. Daniel Rosenfeld in large quantities may also be introduced via the flow of the injected dry air in order to enhance the hurricane controlling ability. All the above factors are in favour of retarding the hurricane's wind speed and power. The sudden weakening of hurricane Lili was found to be partially caused

  8. Hurricane Impacts on Small Island Communities: Case study of Hurricane Matthew on Great Exuma, The Bahamas (United States)

    Sullivan Sealey, Kathleen; Bowleg, John


    Great Exuma has been a UNESCO Eco-hydrology Project Site with a focus on coastal restoration and flood management. Great Exuma and its largest settlement, George Town, support a population of just over 8.000 people on an island dominated by extensive coastal wetlands. The Victoria Pond Eco-Hydrology project restored flow and drainage to highly-altered coastal wetlands to reduce flooding of the built environment as well as regain ecological function. The project was designed to show the value of a protected wetland and coastal environment within a populated settlement; demonstrating that people can live alongside mangroves and value "green" infrastructure for flood protection. The restoration project was initiated after severe storm flooding in 2007 with Tropical Storm Noel. In 2016, the passing of Hurricane Matthew had unprecedented impacts on the coastal communities of Great Exuma, challenging past practices in restoration and flood prevention. This talk reviews the loss of natural capital (for example, fish populations, mangroves, salt water inundation) from Hurricane Matthew based on a rapid response survey of Great Exuma. The surprisingly find was the impact of storm surge on low-lying areas used primarily for personal farms and small-scale agriculture. Although women made up the overwhelming majority of people who attended Coastal Restoration workshops, women were most adversely impacted by the recent hurricane flooding with the loss of their small low-lying farms and gardens. Although increasing culverts in mangrove creeks in two areas did reduce building flood damage, the low-lying areas adjacent to mangroves, mostly ephemeral freshwater wetlands, were inundated with saltwater, and seasonal crops in these areas were destroyed. These ephemeral wetlands were designed as part of the wetland flooding system, it was not known how important these small areas were to artisanal farming on Great Exuma. The size and scope of Hurricane Matthew passing through the

  9. Aftermath of Hurricane Ike along Texas Coast (United States)


    Three weeks after Hurricane Ike came ashore near Galveston, TX, residents returned to find their houses in ruins. From the coast to over 15 km inland, salt water saturated the soil as a result of the 7m storm surge pushed ashore by the force of the hurricane. The right image was acquired on September 28; the left image was acquired August 15, 2006. Vegetation is displayed in red, and inundated areas are in blue-green. Within the inundated area are several small 'red islands' of high ground where salt domes raised the level of the land, and protected the vegetation. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

  10. Spatial structure of directional wave spectra in hurricanes (United States)

    Esquivel-Trava, Bernardo; Ocampo-Torres, Francisco J.; Osuna, Pedro


    The spatial structure of the wave field during hurricane conditions is studied using the National Data Buoy Center directional wave buoy data set from the Caribbean Sea and the Gulf of Mexico. The buoy information, comprising the directional wave spectra during the passage of several hurricanes, was referenced to the center of the hurricane using the path of the hurricane, the propagation velocity, and the radius of the maximum winds. The directional wave spectra were partitioned into their main components to quantify the energy corresponding to the observed wave systems and to distinguish between wind-sea and swell. The findings are consistent with those found using remote sensing data (e.g., Scanning Radar Altimeter data). Based on the previous work, the highest waves are found in the right forward quadrant of the hurricane, where the spectral shape tends to become uni-modal, in the vicinity of the region of maximum winds. More complex spectral shapes are observed in distant regions at the front of and in the rear quadrants of the hurricane, where there is a tendency of the spectra to become bi- and tri-modal. The dominant waves generally propagate at significant angles to the wind direction, except in the regions next to the maximum winds of the right quadrants. Evidence of waves generated by concentric eyewalls associated with secondary maximum winds was also found. The frequency spectra display some of the characteristics of the JONSWAP spectrum adjusted by Young (J Geophys Res 111:8020, 2006); however, at the spectral peak, the similarity with the Pierson-Moskowitz spectrum is clear. These results establish the basis for the use in assessing the ability of numerical models to simulate the wave field in hurricanes.

  17. Mapping Hurricane Rita inland storm tide (United States)

    Berenbrock, Charles; Mason, Jr., Robert R.; Blanchard, Stephen F.; Simonovic, Slobodan P.


    Flood-inundation data are most useful for decision makers when presented in the context of maps of effected communities and (or) areas. But because the data are scarce and rarely cover the full extent of the flooding, interpolation and extrapolation of the information are needed. Many geographic information systems (GIS) provide various interpolation tools, but these tools often ignore the effects of the topographic and hydraulic features that influence flooding. A barrier mapping method was developed to improve maps of storm tide produced by Hurricane Rita. Maps were developed for the maximum storm tide and at 3-hour intervals from midnight (0000 hour) through noon (1200 hour) on September 24, 2005. The improved maps depict storm-tide elevations and the extent of flooding. The extent of storm-tide inundation from the improved maximum storm-tide map was compared to the extent of flood-inundation from a map prepared by the Federal Emergency Management Agency (FEMA). The boundaries from these two maps generally compared quite well especially along the Calcasieu River. Also a cross-section profile that parallels the Louisiana coast was developed from the maximum storm-tide map and included FEMA high-water marks.

  18. Graphical User Interface in Art (United States)

    Gwilt, Ian

    This essay discusses the use of the Graphical User Interface (GUI) as a site of creative practice. By creatively repositioning the GUI as a work of art it is possible to challenge our understanding and expectations of the conventional computer interface wherein the icons and navigational architecture of the GUI no longer function as a technological tool. These artistic recontextualizations are often used to question our engagement with technology and to highlight the pivotal place that the domestic computer has taken in our everyday social, cultural and (increasingly), creative domains. Through these works the media specificity of the screen-based GUI can broken by dramatic changes in scale, form and configuration. This can be seen through the work of new media artists who have re-imagined the GUI in a number of creative forms both, within the digital, as image, animation, net and interactive art, and in the analogue, as print, painting, sculpture, installation and performative event. Furthermore as a creative work, the GUI can also be utilized as a visual way-finder to explore the relationship between the dynamic potentials of the digital and the concretized qualities of the material artifact.

  1. Hurricane Recovery and Ecological Resilience: Measuring the Impacts of Wetland Alteration Post Hurricane Ike on the Upper TX Coast (United States)

    Reja, Md Y.; Brody, Samuel D.; Highfield, Wesley E.; Newman, Galen D.


    Recovery after hurricane events encourages new development activities and allows reconstruction through the conversion of naturally occurring wetlands to other land uses. This research investigates the degree to which hurricane recovery activities in coastal communities are undermining the ability of these places to attenuate the impacts of future storm events. Specifically, it explores how and to what extent wetlands are being affected by the CWA Section 404 permitting program in the context of post-Hurricane Ike 2008 recovery. Wetland alteration patterns are examined by selecting a control group (Aransas and Brazoria counties with no hurricane impact) vs. study group (Chambers and Galveston counties with hurricane impact) research design with a pretest-posttest measurement analyzing the variables such as permit types, pre-post Ike permits, land cover classes, and within-outside the 100-year floodplain. Results show that permitting activities in study group have increased within the 100-year floodplain and palustrine wetlands continue to be lost compare to the control group. Simultaneously, post-Ike individual and nationwide permits increased in the Hurricane Ike impacted area. A binomial logistic regression model indicated that permits within the study group, undeveloped land cover class, and individual and nationwide permit type have a substantial effect on post-Ike permits, suggesting that post-Ike permits have significant impact on wetland losses. These findings indicate that recovery after the hurricane is compromising ecological resiliency in coastal communities. The study outcome may be applied to policy decisions in managing wetlands during a long-term recovery process to maintain natural function for future flood mitigation.

  1. Hurricane Sandy science plan: coastal topographic and bathymetric data to support hurricane impact assessment and response (United States)

    Stronko, Jakob M.


    Hurricane Sandy devastated some of the most heavily populated eastern coastal areas of the Nation. With a storm surge peaking at more than 19 feet, the powerful landscape-altering destruction of Hurricane Sandy is a stark reminder of why the Nation must become more resilient to coastal hazards. In response to this natural disaster, the U.S. Geological Survey (USGS) received a total of $41.2 million in supplemental appropriations from the Department of the Interior (DOI) to support response, recovery, and rebuilding efforts. These funds support a science plan that will provide critical scientific information necessary to inform management decisions for recovery of coastal communities, and aid in preparation for future natural hazards. This science plan is designed to coordinate continuing USGS activities with stakeholders and other agencies to improve data collection and analysis that will guide recovery and restoration efforts. The science plan is split into five distinct themes: • Coastal topography and bathymetry • Impacts to coastal beaches and barriers • Impacts of storm surge, including disturbed estuarine and bay hydrology • Impacts on environmental quality and persisting contaminant exposures • Impacts to coastal ecosystems, habitats, and fish and wildlife This fact sheet focuses on coastal topography and bathymetry.

  3. Hurricane preparedness among elderly residents in South Florida. (United States)

    Kleier, Jo Ann; Krause, Deirdre; Ogilby, Terry


    The purpose of this study was to describe factors associated with hurricane preparation and to test a theoretical model of hurricane preparation decision process among a group of elderly residents living in a high-risk geographical area. This is a descriptive, correlational study. A convenience sample consisted of 188 English-speaking individuals who were aged 55 years or older. In addition to demographic information, two survey instruments were used. Theoretical constructs were operationalized through Moon's Hurricane Preparation Questionnaire. Hurricane preparedness was measured by self-reported responses to FEMA's inventory checklist, which addresses the recommended basic steps of preparation. The theoretical model of hurricane preparation decision process was supported. Main barriers to preparation are the need for cooperation from others and cost of preparation. Participants reported having taken many preparatory steps to shelter-in-place, but too few are prepared if their home were storm-damaged or they should have to evacuate. Findings are consistent with previous studies of samples drawn from similar populations. This report provides guidance as to how public health nurses can become involved with the population and develop interventions based on the constructs of the theoretical model. © 2017 Wiley Periodicals, Inc.

  4. Hurricanes accelerated the Florida-Bahamas lionfish invasion. (United States)

    Johnston, Matthew W; Purkis, Sam J


    In this study, we demonstrate how perturbations to the Florida Current caused by hurricanes are relevant to the spread of invasive lionfish from Florida to the Bahamas. Without such perturbations, this current represents a potential barrier to the transport of planktonic lionfish eggs and larvae across the Straits of Florida. We further show that once lionfish became established in the Bahamas, hurricanes significantly hastened their spread through the island chain. We gain these insights through: (1) an analysis of the direction and velocity of simulated ocean currents during the passage of hurricanes through the Florida Straits and (2) the development of a biophysical model that incorporates the tolerances of lionfish to ocean climate, their reproductive strategy, and duration that the larvae remain viable in the water column. On the basis of this work, we identify 23 occasions between the years 1992 and 2006 in which lionfish were provided the opportunity to breach the Florida Current. We also find that hurricanes during this period increased the rate of spread of lionfish through the Bahamas by more than 45% and magnified its population by at least 15%. Beyond invasive lionfish, we suggest that extreme weather events such as hurricanes likely help to homogenize the gene pool for all Caribbean marine species susceptible to transport. © 2015 John Wiley & Sons Ltd.

  5. Hurricane Risk Variability along the Gulf of Mexico Coastline (United States)

    Trepanier, Jill C.; Ellis, Kelsey N.; Tucker, Clay S.


    Hurricane risk characteristics are examined across the U. S. Gulf of Mexico coastline using a hexagonal tessellation. Using an extreme value model, parameters are collected representing the rate or λ (frequency), the scale or σ (range), and the shape or ξ (intensity) of the extreme wind distribution. These latent parameters and the 30-year return level are visualized across the grid. The greatest 30-year return levels are located toward the center of the Gulf of Mexico, and for inland locations, along the borders of Louisiana, Mississippi, and Alabama. Using a geographically weighted regression model, the relationship of these parameters to sea surface temperature (SST) is found to assess sensitivity to change. It is shown that as SSTs increase near the coast, the frequency of hurricanes in these grids decrease significantly. This reinforces the importance of SST in areas of likely tropical cyclogenesis in determining the number of hurricanes near the coast, along with SSTs along the lifespan of the storm, rather than simply local SST. The range of hurricane wind speeds experienced near Florida is shown to increase with increasing SSTs (insignificant), suggesting that increased temperatures may allow hurricanes to maintain their strength as they pass over the Florida peninsula. The modifiable areal unit problem is assessed using multiple grid sizes. Moran’s I and the local statistic G are calculated to examine spatial autocorrelation in the parameters. This research opens up future questions regarding rapid intensification and decay close to the coast and the relationship to changing SSTs. PMID:25767885

  7. Deaths associated with Hurricane Sandy - October-November 2012. (United States)


    On October 29, 2012, Hurricane Sandy hit the northeastern U.S. coastline. Sandy's tropical storm winds stretched over 900 miles (1,440 km), causing storm surges and destruction over a larger area than that affected by hurricanes with more intensity but narrower paths. Based on storm surge predictions, mandatory evacuations were ordered on October 28, including for New York City's Evacuation Zone A, the coastal zone at risk for flooding from any hurricane. By October 31, the region had 6-12 inches (15-30 cm) of precipitation, 7-8 million customers without power, approximately 20,000 persons in shelters, and news reports of numerous fatalities (Robert Neurath, CDC, personal communication, 2013). To characterize deaths related to Sandy, CDC analyzed data on 117 hurricane-related deaths captured by American Red Cross (Red Cross) mortality tracking during October 28-November 30, 2012. This report describes the results of that analysis, which found drowning was the most common cause of death related to Sandy, and 45% of drowning deaths occurred in flooded homes in Evacuation Zone A. Drowning is a leading cause of hurricane death but is preventable with advance warning systems and evacuation plans. Emergency plans should ensure that persons receive and comprehend evacuation messages and have the necessary resources to comply with them.

  8. Hurricane Loss Analysis Based on the Population-Weighted Index

    Directory of Open Access Journals (Sweden)

    Grzegorz Kakareko


    Full Text Available This paper discusses different measures for quantifying regional hurricane loss. The main measures used in the past are normalized percentage loss and dollar value loss. In this research, we show that these measures are useful but may not properly reflect the size of the population influenced by hurricanes. A new loss measure is proposed that reflects the hurricane impact on people occupying the structure. For demonstrating the differences among these metrics, regional loss analysis was conducted for Florida. The regional analysis was composed of three modules: the hazard module stochastically modeled the wind occurrence in the region; the vulnerability module utilized vulnerability functions developed in this research to calculate the loss; and the financial module quantified the hurricane loss. In the financial module, we calculated three loss metrics for certain region. The first metric is the average annual loss (AAL which represents the expected loss per year in percentage. The second is the average annual dollar loss which represents the expected dollar amount loss per year. The third is the average annual population-weighted loss (AAPL—a new measure proposed in this research. Compared with the AAL, the AAPL reflects the number of people influenced by the hurricane. The advantages of the AAPL are illustrated using three different analysis examples: (1 conventional regional loss analysis, (2 mitigation potential analysis, and (3 forecasted future loss analysis due to the change in population.

  9. Numerical study of sediment dynamics during hurricane Gustav (United States)

    Zang, Zhengchen; Xue, Z. George; Bao, Shaowu; Chen, Qin; Walker, Nan D.; Haag, Alaric S.; Ge, Qian; Yao, Zhigang


    In this study, the coupled ocean-atmosphere-wave-and-sediment transport (COAWST) modeling system was employed to explore sediment dynamics in the northern Gulf of Mexico during hurricane Gustav in 2008. The performance of the model was evaluated quantitatively and qualitatively against in-situ and remote sensing measurements, respectively. After Gustav's landfall in coastal Louisiana, the maximum significant wave heights reached more than 8 m offshore and they decreased quickly as it moved toward the inner shelf, where the vertical stratification was largely destroyed. Alongshore currents were dominant westward on the eastern sector of the hurricane track, and offshoreward currents prevailed on the western sector. High suspended sediment concentrations (>1000 mg/l) were confined to the inner shelf at surface layers and the simulated high concentrations at the bottom layer extended to the 200 m isobaths. The stratification was restored one week after landfall, although not fully. The asymmetric hurricane winds induced stronger hydrodynamics in the eastern sector, which led to severe erosion. The calculated suspended sediment flux (SSF) was convergent to the hurricane center and the maximum SSF was simulated near the south and southeast of the Mississippi river delta. The averaged post-hurricane deposition over the Louisiana shelf was 4.0 cm, which was 3.2-26 times higher than the annual accumulation rate under normal weather conditions.

  10. Changes in trace metals in Thalassia testudinum after hurricane impacts. (United States)

    Whelan, T; Van Tussenbroek, B I; Santos, M G Barba


    Major hurricanes Emily and Wilma hit the Mexican Caribbean in 2005. Changes in trace metals in the seagrass Thalassia testudinum prior to (May 2004, 2005) and following passage of these hurricanes (May, June 2006) were determined at four locations along a ≈ 130 km long stretch of coast. Before the hurricanes, essential metals were likely limiting and concentrations of potentially toxic Pb were high in a contaminated lagoon (27.5 μg g(-1)) and near submarine springs (6.10 μg g(-1)); the likely sources were inland sewage disposal or excessive boat traffic. After the hurricanes, Pb decreased to 2.0 μg g(-1) in the contaminated lagoon probably through flushing. At the northern sites, essential Fe increased >2-fold (from 26.8 to 68.3 μg g(-1) on average), possibly from remobilization of anoxic sediments or upwelling of deep seawater during Wilma. Thus, hurricanes can be beneficial to seagrass beds in flushing toxic metals and replenishing essential elements. Copyright © 2011 Elsevier Ltd. All rights reserved.

  12. The graphics future in scientific applications

    International Nuclear Information System (INIS)

    Enderle, G.


    Computer graphics methods and tools are being used to a great extent in scientific research. The future development in this area will be influenced both by new hardware developments and by software advances. On the hardware sector, the development of the raster technology will lead to the increased use of colour workstations with more local processing power. Colour hardcopy devices for creating plots, slides, or movies will be available at a lower price than today. The first real 3D-workstations appear on the marketplace. One of the main activities on the software sector is the standardization of computer graphics systems, graphical files, and device interfaces. This will lead to more portable graphical application programs and to a common base for computer graphics education. (orig.)

  14. From the "Modern Synthesis" to cybernetics: Ivan Ivanovich Schmalhausen (1884-1963) and his research program for a synthesis of evolutionary and developmental biology. (United States)

    Levit, Georgy S; Hossfeld, Uwe; Olsson, Lennart


    Ivan I. Schmalhausen was one of the central figures in the Russian development of the "Modern Synthesis" in evolutionary biology. He is widely cited internationally even today. Schmalhausen developed the main principles of his theory facing the danger of death in the totalitarian Soviet Union. His great services to evolutionary and theoretical biology are indisputable. However, the received view of Schmalhausen's contributions to evolutionary biology makes an unbiased reading of his texts difficult. Here we show that taking all of his works into consideration (including those only available in Russian) paints a much more dynamic and exciting picture of what he tried to achieve. Schmalhausen pioneered the integration of a developmental perspective into evolutionary thinking. A main tool for achieving this was his approach to living objects as complex multi-level self-regulating systems. Schmalhausen put enormous effort into bringing this idea into fruition during the final stages of his career by combining evolutionary theory with cybernetics. His results and ideas remain thought-provoking, and his texts are of more than just historical interest. Copyright 2006 Wiley-Liss, Inc.

    Full Text Available The new Grohar’s room in the Škofja Loka Mu¬seum that is located in a more than a thousand years old town, some kilometres northwest of Ljubljana, Slove¬nia, represents one of the new possibilities to popularize old local history. Ivan Grohar (1867−1911 is one of the four well-known Slovenian painters from the beginning of the 20th century, together with Rihard Jakopič, Matija Jama and Matej Sternen. These Slovenian painters are the founders of Impressionism within the modern style. Škofja Loka became the so called Slovenian “Barbizon” (i.e. French village near Fontainebleau, once the settle-ment of painters and this art and old tradition inspired another Slovenian (music artist Oskar Dev (1868−1932, who composed some of his musical works (songs and choirs in Škofja Loka, too. His and Grohar’s period in Škofja Loka resulted in some extraordinary art works i.e. paintings and musical works. They both were inspired by the countryside that reflected on their works. This is now one of the new Slovenian’s challenges of museology and musicology in an interdisciplinary and multidisciplinary approach so the art of painting and music could be a benefit for the visitors of this and other museums.

  17. "Just-in-Time" Personal Preparedness: Downloads and Usage Patterns of the American Red Cross Hurricane Application During Hurricane Sandy. (United States)

    Kirsch, Thomas D; Circh, Ryan; Bissell, Richard A; Goldfeder, Matthew


    Personal preparedness is a core activity but has been found to be frequently inadequate. Smart phone applications have many uses for the public, including preparedness. In 2012 the American Red Cross began releasing "disaster" apps for family preparedness and recovery. The Hurricane App was widely used during Hurricane Sandy in 2012. Patterns of download of the application were analyzed by using a download tracking tool by the American Red Cross and Google Analytics. Specific variables included date, time, and location of individual downloads; number of page visits and views; and average time spent on pages. As Hurricane Sandy approached in late October, daily downloads peaked at 152,258 on the day of landfall and by mid-November reached 697,585. Total page views began increasing on October 25 with over 4,000,000 page views during landfall compared to 3.7 million the first 3 weeks of October with a 43,980% increase in views of the "Right Before" page and a 76,275% increase in views of the "During" page. The Hurricane App offered a new type of "just-in-time" training that reached tens of thousands of families in areas affected by Hurricane Sandy. The app allowed these families to access real-time information before and after the storm to help them prepare and recover. (Disaster Med Public Health Preparedness. 2016;page 1 of 6).

  18. Assessment of Risk of Cholera in Haiti following Hurricane Matthew. (United States)

    Khan, Rakib; Anwar, Rifat; Akanda, Shafqat; McDonald, Michael D; Huq, Anwar; Jutla, Antarpreet; Colwell, Rita


    Damage to the inferior and fragile water and sanitation infrastructure of Haiti after Hurricane Matthew has created an urgent public health emergency in terms of likelihood of cholera occurring in the human population. Using satellite-derived data on precipitation, gridded air temperature, and hurricane path and with information on water and sanitation (WASH) infrastructure, we tracked changing environmental conditions conducive for growth of pathogenic vibrios. Based on these data, we predicted and validated the likelihood of cholera cases occurring past hurricane. The risk of cholera in the southwestern part of Haiti remained relatively high since November 2016 to the present. Findings of this study provide a contemporary process for monitoring ground conditions that can guide public health intervention to control cholera in human population by providing access to vaccines, safe WASH facilities. Assuming current social and behavioral patterns remain constant, it is recommended that WASH infrastructure should be improved and considered a priority especially before 2017 rainy season.

  19. Mold exposure and health effects following hurricanes Katrina and Rita. (United States)

    Barbeau, Deborah N; Grimsley, L Faye; White, LuAnn E; El-Dahr, Jane M; Lichtveld, Maureen


    The extensive flooding in the aftermath of Hurricanes Katrina and Rita created conditions ideal for indoor mold growth, raising concerns about the possible adverse health effects associated with indoor mold exposure. Studies evaluating the levels of indoor and outdoor molds in the months following the hurricanes found high levels of mold growth. Homes with greater flood damage, especially those with >3 feet of indoor flooding, demonstrated higher levels of mold growth compared with homes with little or no flooding. Water intrusion due to roof damage was also associated with mold growth. However, no increase in the occurrence of adverse health outcomes has been observed in published reports to date. This article considers reasons why studies of mold exposure after the hurricane do not show a greater health impact.

  20. Hurricane Harvey Building Damage Assessment Using UAV Data (United States)

    Yeom, J.; Jung, J.; Chang, A.; Choi, I.


    Hurricane Harvey which was extremely destructive major hurricane struck southern Texas, U.S.A on August 25, causing catastrophic flooding and storm damages. We visited Rockport suffered severe building destruction and conducted UAV (Unmanned Aerial Vehicle) surveying for building damage assessment. UAV provides very high resolution images compared with traditional remote sensing data. In addition, prompt and cost-effective damage assessment can be performed regardless of several limitations in other remote sensing platforms such as revisit interval of satellite platforms, complicated flight plan in aerial surveying, and cloud amounts. In this study, UAV flight and GPS surveying were conducted two weeks after hurricane damage to generate an orthomosaic image and a DEM (Digital Elevation Model). 3D region growing scheme has been proposed to quantitatively estimate building damages considering building debris' elevation change and spectral difference. The result showed that the proposed method can be used for high definition building damage assessment in a time- and cost-effective way.

  1. Low ionospheric reactions on tropical depressions prior hurricanes (United States)

    Nina, Aleksandra; Radovanović, Milan; Milovanović, Boško; Kovačević, Andjelka; Bajčetić, Jovan; Popović, Luka Č.


    We study the reactions of the low ionosphere during tropical depressions (TDs) which have been detected before the hurricane appearances in the Atlantic Ocean. We explore 41 TD events using very low frequency (VLF) radio signals emitted by NAA transmitter located in the USA and recorded by VLF receiver located in Belgrade (Serbia). We found VLF signal deviations (caused ionospheric turbulence) in the case of 36 out of 41 TD events (88%). Additionally, we explore 27 TDs which have not been developed in hurricanes and found similar low ionospheric reactions. However, in the sample of 41 TDs which are followed by hurricanes the typical low ionosphere perturbations seem to be more frequent than other TDs.

  2. Hydrologic aspects of Hurricane Hugo in South Carolina, September 1989 (United States)

    Schuck-Kolben, R. E.; Cherry, R.N.


    Hurricane Hugo, with winds in excess of 135 miles per hour(mi/h), made landfall near Charleston, S.C., early on the morning of September 22, 1989. It was the most destructive hurricane ever experienced in South Carolina. The storm caused 35 deaths and $7 billion in property damage in South Carolina (Purvis, 1990).This report documents some hydrologic effects of Hurricane Hugo along the South Carolina coast. The report includes maps showing storm-tide stage and profiles of the maximum storm-tide stages along the outer coast. Storm-tide stage frequency information is presented and changes in beach morphology and water quality of coastal streams resulting from the storm are described.

  3. Psychological distress of adolescents exposed to Hurricane Hugo. (United States)

    Hardin, S B; Weinrich, M; Weinrich, S; Hardin, T L; Garrison, C


    To ascertain the effects of a natural disaster on adolescents, 1482 South Carolina high school students who were exposed to Hurricane Hugo were surveyed 1 year after the disaster. Subjects completed a self-administered questionnaire measuring Hugo exposure, nonviolent and violent life events, social support, self-efficacy, and psychological distress. Results showed that the students reported minimal exposure to the hurricane and psychological distress variables approximated national norms. As exposure increased, adolescents reported increased symptoms of psychological distress; i.e., anger, depression, anxiety, and global mental distress. Females and white students experienced higher levels of distress. In most cases, other stressful life events were at least as strong a predictor of psychological distress as was exposure to the hurricane. Self-efficacy and social support were protective.

  4. Saharan Dust, Transport Processes, and Possible Impacts on Hurricane Activities (United States)

    Lau, William K. M.; Kim, K. M.


    In this paper, we present observational evidence of significant relationships between Saharan dust outbreak, and African Easterly wave activities and hurricane activities. We found two dominant paths of transport of Saharan dust: a northern path, centered at 25degN associated with eastward propagating 6-19 days waves over northern Africa, and a southern path centered at 15degN, associated with the AEW, and the Atlantic ITCZ. Seasons with stronger dust outbreak from the southern path are associated with a drier atmosphere over the Maximum Development Region (MDR) and reduction in tropical cyclone and hurricane activities in the MDR. Seasons with stronger outbreak from the northern path are associated with a cooler N. Atlantic, and suppressed hurricane in the western Atlantic basin.

  5. Biogeochemical Impact of Hurricane Harvey on Texas Coastal Lagoons (United States)

    Montagna, P.; Hu, X.; Walker, L.; Wetz, M.


    Hurricane Harvey made landfall Friday 25 August 2017 as a Category 4 hurricane, which is the strongest hurricane to hit the middle Texas coast since Carla in 1961. After the wind storm and storm surge, coastal flooding occurred due to the storm lingering over Texas for four more days, dumping as much as 50" of rain near Houston, producing 1:1000 year flood event. The Texas coast is characterized by lagoons behind barrier islands, and their ecology and biogeochemistry are strongly influenced by coastal hydrology. The ensuing inflow event replaced brackish water with fresh water that was high in inorganic an organic matter, significantly enhancing respiration of coastal blue carbon, and dissolved oxygen went to zero for a long period of time. Recovery will likely take months or nearly one year.

  6. Longitudinal Impact of Hurricane Sandy Exposure on Mental Health Symptoms

    Directory of Open Access Journals (Sweden)

    Rebecca M. Schwartz


    Full Text Available Hurricane Sandy hit the eastern coast of the United States in October 2012, causing billions of dollars in damage and acute physical and mental health problems. The long-term mental health consequences of the storm and their predictors have not been studied. New York City and Long Island residents completed questionnaires regarding their initial Hurricane Sandy exposure and mental health symptoms at baseline and 1 year later (N = 130. There were statistically significant decreases in anxiety scores (mean difference = −0.33, p < 0.01 and post-traumatic stress disorder (PTSD scores (mean difference = −1.98, p = 0.001 between baseline and follow-up. Experiencing a combination of personal and property damage was positively associated with long-term PTSD symptoms (ORadj 1.2, 95% CI [1.1–1.4] but not with anxiety or depression. Having anxiety, depression, or PTSD at baseline was a significant predictor of persistent anxiety (ORadj 2.8 95% CI [1.1–6.8], depression (ORadj 7.4 95% CI [2.3–24.1 and PTSD (ORadj 4.1 95% CI [1.1–14.6] at follow-up. Exposure to Hurricane Sandy has an impact on PTSD symptoms that persists over time. Given the likelihood of more frequent and intense hurricanes due to climate change, future hurricane recovery efforts must consider the long-term effects of hurricane exposure on mental health, especially on PTSD, when providing appropriate assistance and treatment.

  7. Maternal exposure to hurricane destruction and fetal mortality. (United States)

    Zahran, Sammy; Breunig, Ian M; Link, Bruce G; Snodgrass, Jeffrey G; Weiler, Stephan; Mielke, Howard W


    The majority of research documenting the public health impacts of natural disasters focuses on the well-being of adults and their living children. Negative effects may also occur in the unborn, exposed to disaster stressors when critical organ systems are developing and when the consequences of exposure are large. We exploit spatial and temporal variation in hurricane behaviour as a quasi-experimental design to assess whether fetal death is dose-responsive in the extent of hurricane damage. Data on births and fetal deaths are merged with Parish-level housing wreckage data. Fetal outcomes are regressed on housing wreckage adjusting for the maternal, fetal, placental and other risk factors. The average causal effect of maternal exposure to hurricane destruction is captured by difference-in-differences analyses. The adjusted odds of fetal death are 1.40 (1.07-1.83) and 2.37 (1.684-3.327) times higher in parishes suffering 10-50% and >50% wreckage to housing stock, respectively. For every 1% increase in the destruction of housing stock, we observe a 1.7% (1.1-2.4%) increase in fetal death. Of the 410 officially recorded fetal deaths in these parishes, between 117 and 205 may be attributable to hurricane destruction and postdisaster disorder. The estimated fetal death toll is 17.4-30.6% of the human death toll. The destruction caused by Hurricanes Katrina and Rita imposed significant measurable losses in terms of fetal death. Postdisaster migratory dynamics suggest that the reported effects of maternal exposure to hurricane destruction on fetal death may be conservative. Published by the BMJ Publishing Group Limited.

  8. EarthLabs - Investigating Hurricanes: Earth's Meteorological Monsters (United States)

    McDaris, J. R.; Dahlman, L.; Barstow, D.


    Earth science is one of the most important tools that the global community needs to address the pressing environmental, social, and economic issues of our time. While, at times considered a second-rate science at the high school level, it is currently undergoing a major revolution in the depth of content and pedagogical vitality. As part of this revolution, labs in Earth science courses need to shift their focus from cookbook-like activities with known outcomes to open-ended investigations that challenge students to think, explore and apply their learning. We need to establish a new model for Earth science as a rigorous lab science in policy, perception, and reality. As a concerted response to this need, five states, a coalition of scientists and educators, and an experienced curriculum team are creating a national model for a lab-based high school Earth science course named EarthLabs. This lab course will comply with the National Science Education Standards as well as the states' curriculum frameworks. The content will focus on Earth system science and environmental literacy. The lab experiences will feature a combination of field work, classroom experiments, and computer access to data and visualizations, and demonstrate the rigor and depth of a true lab course. The effort is being funded by NOAA's Environmental Literacy program. One of the prototype units of the course is Investigating Hurricanes. Hurricanes are phenomena which have tremendous impact on humanity and the resources we use. They are also the result of complex interacting Earth systems, making them perfect objects for rigorous investigation of many concepts commonly covered in Earth science courses, such as meteorology, climate, and global wind circulation. Students are able to use the same data sets, analysis tools, and research techniques that scientists employ in their research, yielding truly authentic learning opportunities. This month-long integrated unit uses hurricanes as the story line by

    Ackerson, T.


    The Office Automation Pilot (OAP) Graphics Database system offers the IBM PC user assistance in producing a wide variety of graphs and charts. OAP uses a convenient database system, called a chartbase, for creating and maintaining data associated with the charts, and twelve different graphics packages are available to the OAP user. Each of the graphics capabilities is accessed in a similar manner. The user chooses creation, revision, or chartbase/slide show maintenance options from an initial menu. The user may then enter or modify data displayed on a graphic chart. The cursor moves through the chart in a "circular" fashion to facilitate data entries and changes. Various "help" functions and on-screen instructions are available to aid the user. The user data is used to generate the graphics portion of the chart. Completed charts may be displayed in monotone or color, printed, plotted, or stored in the chartbase on the IBM PC. Once completed, the charts may be put in a vector format and plotted for color viewgraphs. The twelve graphics capabilities are divided into three groups: Forms, Structured Charts, and Block Diagrams. There are eight Forms available: 1) Bar/Line Charts, 2) Pie Charts, 3) Milestone Charts, 4) Resources Charts, 5) Earned Value Analysis Charts, 6) Progress/Effort Charts, 7) Travel/Training Charts, and 8) Trend Analysis Charts. There are three Structured Charts available: 1) Bullet Charts, 2) Organization Charts, and 3) Work Breakdown Structure (WBS) Charts. The Block Diagram available is an N x N Chart. Each graphics capability supports a chartbase. The OAP graphics database system provides the IBM PC user with an effective means of managing data which is best interpreted as a graphic display. The OAP graphics database system is written in IBM PASCAL 2.0 and assembler for interactive execution on an IBM PC or XT with at least 384K of memory, and a color graphics adapter and monitor. Printed charts require an Epson, IBM, OKIDATA, or HP Laser

    Objective . To report on changes in sensitivity to mold allergens determined by changes in intradermal skin testing reactivity, after exposure to two severe hurricanes. Methods . A random, retrospective allergy charts review divided into 2 groups of 100 patients each: Group A, patients tested between 2003 and 2010 prior to hurricanes, and Group B, patients tested in 2014 and 2015 following hurricanes. Reactivity to eighteen molds was determined by intradermal skin testing. Test results, age, and respiratory symptoms were recorded. Chi-square test determined reactivity/sensitivity differences between groups. Results . Posthurricane patients had 34.6 times more positive results ( p hurricanes ( p hurricanes ( p hurricanes. This supports climatologists' hypothesis that environmental changes resulting from hurricanes can be a health risk as reflected in increased allergic sensitivities and symptoms and has significant implications for physicians treating patients from affected areas.

  4. On the relationship between hurricane cost and the integrated wind profile (United States)

    Wang, S.; Toumi, R.


    It is challenging to identify metrics that best capture hurricane destructive potential and costs. Although it has been found that the sea surface temperature and vertical wind shear can both make considerable changes to the hurricane destructive potential metrics, it is still unknown which plays a more important role. Here we present a new method to reconstruct the historical wind structure of hurricanes that allows us, for the first time, to calculate the correlation of damage with integrated power dissipation and integrated kinetic energy of all hurricanes at landfall since 1988. We find that those metrics, which include the horizontal wind structure, rather than just maximum intensity, are much better correlated with the hurricane cost. The vertical wind shear over the main development region of hurricanes plays a more dominant role than the sea surface temperature in controlling these metrics and therefore also ultimately the cost of hurricanes.

    Computer graphics has many forms. When applied in medicine, it can range from simple two dimensional charts and graphs to rendering of three-dimensional scenes. Computer graphic displays of molecular or large anatomic structures have been used to great advantage by numerous medical researchers. In addition, graphic presentations can be dynamic where displays are controlled by physician-user commands, or the presentations can be static, where views are recorded in discrete frames for later distribution or permanent archival. In medicine both interactive and static forms of computer graphics have their proper place in the effective delivery of health care. Computer graphics, however, changes constantly in the area of software techniques, hardware improvements and its clinical application. What may be medically appropriate today in the use of computer graphics can soon become inadequate and well behind the new advances that so quickly follow. In this paper the key feature of computer communication is discussed that aids in the clinical utility of computer graphics in medicine. It is distribution. Distribution in terms of instantaneous computer graphic software updates and more importantly, distribution of meaningful three-dimensional presentations to referring physicians. Physicians who, working in their private offices, have no routine access to medical work stations. In this environment three dimensional presentations of anatomy are static in nature, but must deliver realistic views of critical structures. This paper outlines how computer communication provides the essential ingredient to the provision of this service. As an illustration, the electronic distribution of software to generate three dimensional views of complex anatomoic structures is discussed. Sample views are included

  12. Anthroposcenes: Towards an Environmental Graphic Novel

    Directory of Open Access Journals (Sweden)

    Laura Perry


    Full Text Available In this article, I consider how two contemporary graphic novels, Richard McGuire’s 'Here' (2015 and Lauren Redniss’s 'Radioactive' (2010, take up the challenge posed by the Anthropocene to represent both geologic and human scales. I argue that graphic novels prove a fruitful site for investigating the capacities of both visual art and literature to respond to such a refiguring of the boundaries of the human subject and narrative. While the most commercially popular and frequently studied texts in climate fiction tend to be novels or films, I turn from considering the patterns of genre fiction to the affordances of form. I explore how the conceptual and aesthetic frameworks of the graphic novel form encompass environmental phenomena that are often difficult to visualize elsewhere, stretching beyond human perspectives. In particular, I show how the aesthetics of temporality, or visual time, in graphic novels encourages readings that take notice of the nonhuman presence in plots and narrative events. In arguing for the environmental, more-than-human implications of visual time in the graphic novel form, I focus on how representations of domestic habits and daily routines in 'Here' and 'Radioactive' are articulated within and implicated by unruly scales of time and space (too small and too large to contain. I argue that the aesthetics of time in the form of the graphic novel address representational challenges central to the Anthropocene, environmental justice, and slow violence, in particular, the mediation between the planetary and the domestic.

  13. A Linux Workstation for High Performance Graphics (United States)

    Geist, Robert; Westall, James


    The primary goal of this effort was to provide a low-cost method of obtaining high-performance 3-D graphics using an industry standard library (OpenGL) on PC class computers. Previously, users interested in doing substantial visualization or graphical manipulation were constrained to using specialized, custom hardware most often found in computers from Silicon Graphics (SGI). We provided an alternative to expensive SGI hardware by taking advantage of third-party, 3-D graphics accelerators that have now become available at very affordable prices. To make use of this hardware our goal was to provide a free, redistributable, and fully-compatible OpenGL work-alike library so that existing bodies of code could simply be recompiled. for PC class machines running a free version of Unix. This should allow substantial cost savings while greatly expanding the population of people with access to a serious graphics development and viewing environment. This should offer a means for NASA to provide a spectrum of graphics performance to its scientists, supplying high-end specialized SGI hardware for high-performance visualization while fulfilling the requirements of medium and lower performance applications with generic, off-the-shelf components and still maintaining compatibility between the two.

  14. Picturing Illness: History, Poetics, and Graphic Medicine

    Directory of Open Access Journals (Sweden)

    Raghavi Ravi Kasthuri


    Full Text Available Comics have often been treated as a juvenile and sub-literary art form; however, taking cues from the new-found cultural acceptance of comics, particularly with the publication of Art Spiegelman’s Maus (1986, Chris Ware’s Jimmy Corrigan: The Smartest Kid on Earth (2000, and Alison Bechdel’s Fun Home: A Family Tragedy (2006, there have emerged, over the past decade, a new breed of comics dealing with the patient/caregivers’ experiences, perspectives and identities. Christened as graphic medicine, these illness narratives use comics as a medium to address wide ranging disease/illness related issues. The present review examines the following issues: What is graphic medicine? Is there a tangible relationship between underground comics and graphic medicine? If so, can we regard underground comics as historical precedent to graphic medicine? What are the uses of comics in medicine? Broadly put, drawing examples from various graphic medical narratives, the paper seeks to trace the history and poetics of graphic medicine.

  15. Contrasting Hydrodynamic and Environmental Effects of Hurricanes Harvey and Ike in a Highly Industrialized Estuary (United States)

    Kiaghadi, A.; Rifai, H. S.


    It is commonly believed that storm surge is the most destructive aspect of hurricanes. However, massive rainfall with a return period of 100 years or more induced by hurricanes can cause more catastrophic damage than losses caused by storm surge as demonstrated recently by hurricanes Harvey, Irma and Maria. In this study the hydrodynamics and environmental effects of hurricanes Ike and Harvey were compared and contrasted by linking hydrodynamic flow models with water quality models to simulate spills from storage tanks located in the Houston Ship Channel (HSC). Hurricane Ike with a maximum surge of 5.3 meters in Galveston Bay and Harvey with a maximum rainfall of 1.25 meters both struck the HSC region in Texas in 2008 and 2017, respectively. Both events resulted in numerous spills from municipal and industrial facilities, hazardous waste sites, superfund sites, and landfills. The Environmental Fluid Dynamic Code (EFDC) was coupled with the SWAN+ADCIRC hurricane simulation model to simulate Hurricane Ike and EFDC was coupled with USGS flow boundary conditions to model Hurricane Harvey. A conservative dye release was used to simulate a chemical release during each event. The results showed Hurricane Harvey caused higher water surface elevations within the HSC accompanied by longer and wider-spread land inundation. In contrast, higher water surface elevations were observed within the shallow side bays during Hurricane Ike that caused sediment resuspension and repartitioning of pollutants. Rapid spill mass transportation was observed for both hurricanes; 50% of total spill mass reached Galveston Bay in 20 and 22 hours after a spill event for Hurricane Harvey and Ike, respectively, and more than 90% of the spill mass reached the bay in 36 and 48 hours, respectively. Unlike Hurricane Harvey, the conservative tracer was spread almost 2.5 km upstream of the releasing point for Hurricane Ike due to surge. However, during Harvey, 35% more land was affected by the spilled

  19. Hurricane disturbance benefits nesting American Oystercatchers (Haematopus palliatus) (United States)

    Simons, Theodore R.; Schulte, Shiloh A.


    Coastal ecosystems are under increasing pressure from human activity, introduced species, sea level rise, and storm activity. Hurricanes are a powerful destructive force, but can also renew coastal habitats. In 2003, Hurricane Isabel altered the barrier islands of North Carolina, flattening dunes and creating sand flats. American Oystercatchers (Haematopus palliatus) are large shorebirds that inhabit the coastal zone throughout the year. Alternative survival models were evaluated for 699 American Oystercatcher nests on North Core Banks and South Core Banks, North Carolina, USA, from 1999–2007. Nest survival on North Core Banks increased from 0.170 (SE = 0.002) to 0.772 (SE = 0.090) after the hurricane, with a carry-over effect lasting 2 years. A simple year effects model described nest survival on South Core Banks. Habitat had no effect on survival except when the overall rate of nest survival was at intermediate levels (0.300–0.600), when nests on open flats survived at a higher rate (0.600; SE = 0.112) than nests in dune habitat (0.243; SE = 0.094). Predator activity declined on North Core Banks after the hurricane and corresponded with an increase in nest survival. Periodic years with elevated nest survival may offset low annual productivity and contribute to the stability of American Oystercatcher populations.

  2. Hurricane-induced failure of low salinity wetlands (United States)

    Howes, Nick C.; FitzGerald, Duncan M.; Hughes, Zoe J.; Georgiou, Ioannis Y.; Kulp, Mark A.; Miner, Michael D.; Smith, Jane M.; Barras, John A.


    During the 2005 hurricane season, the storm surge and wave field associated with Hurricanes Katrina and Rita eroded 527 km2 of wetlands within the Louisiana coastal plain. Low salinity wetlands were preferentially eroded, while higher salinity wetlands remained robust and largely unchanged. Here we highlight geotechnical differences between the soil profiles of high and low salinity regimes, which are controlled by vegetation and result in differential erosion. In low salinity wetlands, a weak zone (shear strength 500–1450 Pa) was observed ∼30 cm below the marsh surface, coinciding with the base of rooting. High salinity wetlands had no such zone (shear strengths > 4500 Pa) and contained deeper rooting. Storm waves during Hurricane Katrina produced shear stresses between 425–3600 Pa, sufficient to cause widespread erosion of the low salinity wetlands. Vegetation in low salinity marshes is subject to shallower rooting and is susceptible to erosion during large magnitude storms; these conditions may be exacerbated by low inorganic sediment content and high nutrient inputs. The dramatic difference in resiliency of fresh versus more saline marshes suggests that the introduction of freshwater to marshes as part of restoration efforts may therefore weaken existing wetlands rendering them vulnerable to hurricanes.

  5. Quantifying the hurricane catastrophe risk to offshore wind power. (United States)

    Rose, Stephen; Jaramillo, Paulina; Small, Mitchell J; Apt, Jay


    The U.S. Department of Energy has estimated that over 50 GW of offshore wind power will be required for the United States to generate 20% of its electricity from wind. Developers are actively planning offshore wind farms along the U.S. Atlantic and Gulf coasts and several leases have been signed for offshore sites. These planned projects are in areas that are sometimes struck by hurricanes. We present a method to estimate the catastrophe risk to offshore wind power using simulated hurricanes. Using this method, we estimate the fraction of offshore wind power simultaneously offline and the cumulative damage in a region. In Texas, the most vulnerable region we studied, 10% of offshore wind power could be offline simultaneously because of hurricane damage with a 100-year return period and 6% could be destroyed in any 10-year period. We also estimate the risks to single wind farms in four representative locations; we find the risks are significant but lower than those estimated in previously published results. Much of the hurricane risk to offshore wind turbines can be mitigated by designing turbines for higher maximum wind speeds, ensuring that turbine nacelles can turn quickly to track the wind direction even when grid power is lost, and building in areas with lower risk. © 2013 Society for Risk Analysis.

    A natural disaster in the form of Hurricane Fran resulted not only in stories of ingenuity and compassion, but in a major performance improvement (PI) process for the entire agency. Through this PI process we learned about ourselves as a home health agency and discovered ways to improve our performance. More importantly we discovered ways to improve patient tracking and care during a disaster.

  7. Hurricane Irene: a Wake Up Call for New York City?

    NARCIS (Netherlands)

    Aerts, J.C.J.H.; Botzen, W.J.W.


    The weakening of Irene from a Category 3 hurricane to a tropical storm resulted in less damage in New York City (NYC) than initially was anticipated. It is widely recognized that the storm surge and associated flooding could have been much more severe. In a recent study, we showed that a direct hit

  8. Optimization of Evacuation Warnings Prior to a Hurricane Disaster

    Directory of Open Access Journals (Sweden)

    Dian Sun


    Full Text Available The key purpose of this paper is to demonstrate that optimization of evacuation warnings by time period and impacted zone is crucial for efficient evacuation of an area impacted by a hurricane. We assume that people behave in a manner consistent with the warnings they receive. By optimizing the issuance of hurricane evacuation warnings, one can control the number of evacuees at different time intervals to avoid congestion in the process of evacuation. The warning optimization model is applied to a case study of Hurricane Sandy using the study region of Brooklyn. We first develop a model for shelter assignment and then use this outcome to model hurricane evacuation warning optimization, which prescribes an evacuation plan that maximizes the number of evacuees. A significant technical contribution is the development of an iterative greedy heuristic procedure for the nonlinear formulation, which is shown to be optimal for the case of a single evacuation zone with a single evacuee type case, while it does not guarantee optimality for multiple zones under unusual circumstances. A significant applied contribution is the demonstration of an interface of the evacuation warning method with a public transportation scheme to facilitate evacuation of a car-less population. This heuristic we employ can be readily adapted to the case where response rate is a function of evacuation number in prior periods and other variable factors. This element is also explored in the context of our experiment.

  10. Hurricane Mitch: Peak Discharge for Selected River Reachesin Honduras (United States)

    Smith, Mark E.; Phillips, Jeffrey V.; Spahr, Norman E.


    Hurricane Mitch began as a tropical depression in the Caribbean Sea on 22 October 1998. By 26 October, Mitch had strengthened to a Category 5 storm as defined by the Saffir-Simpson Hurricane Scale (National Climate Data Center, 1999a), and on 27 October was threatening the northern coast of Honduras (fig. 1). After making landfall 2 days later (29 October), the storm drifted south and west across Honduras, wreaking destruction throughout the country before reaching the Guatemalan border on 31 October. According to the National Climate Data Center of the National Oceanic and Atmospheric Administration (National Climate Data Center, 1999b), Hurricane Mitch ranks among the five strongest storms on record in the Atlantic Basin in terms of its sustained winds, barometric pressure, and duration. Hurricane Mitch also was one of the worst Atlantic storms in terms of loss of life and property. The regionwide death toll was estimated to be more than 9,000; thousands of people were reported missing. Economic losses in the region were more than $7.5 billion (U.S. Agency for International Development, 1999). Honduras suffered the most widespread devastation during the storm. More than 5,000 deaths, and economic losses of more than $4 billion, were reported by the Government of Honduras. Honduran officials estimated that Hurricane Mitch destroyed 50 years of economic development. In addition to the human and economic losses, intense flooding and landslides scarred the Honduran landscape - hydrologic and geomorphologic processes throughout the country likely will be affected for many years. As part of the U.S. Government's response to the disaster, the U.S. Geological Survey (USGS) conducted post-flood measurements of peak discharge at 16 river sites throughout Honduras (fig. 2). Such measurements, termed 'indirect' measurements, are used to determine peak flows when direct measurements (using current meters or dye studies, for example) cannot be made. Indirect measurements of

  11. Quantifying human mobility perturbation and resilience in Hurricane Sandy.

    Qi Wang

    Full Text Available Human mobility is influenced by environmental change and natural disasters. Researchers have used trip distance distribution, radius of gyration of movements, and individuals' visited locations to understand and capture human mobility patterns and trajectories. However, our knowledge of human movements during natural disasters is limited owing to both a lack of empirical data and the low precision of available data. Here, we studied human mobility using high-resolution movement data from individuals in New York City during and for several days after Hurricane Sandy in 2012. We found the human movements followed truncated power-law distributions during and after Hurricane Sandy, although the β value was noticeably larger during the first 24 hours after the storm struck. Also, we examined two parameters: the center of mass and the radius of gyration of each individual's movements. We found that their values during perturbation states and steady states are highly correlated, suggesting human mobility data obtained in steady states can possibly predict the perturbation state. Our results demonstrate that human movement trajectories experienced significant perturbations during hurricanes, but also exhibited high resilience. We expect the study will stimulate future research on the perturbation and inherent resilience of human mobility under the influence of hurricanes. For example, mobility patterns in coastal urban areas could be examined as hurricanes approach, gain or dissipate in strength, and as the path of the storm changes. Understanding nuances of human mobility under the influence of such disasters will enable more effective evacuation, emergency response planning and development of strategies and policies to reduce fatality, injury, and economic loss.

  12. Lightning and radar observations of hurricane Rita landfall

    Energy Technology Data Exchange (ETDEWEB)

    Henderson, Bradley G [Los Alamos National Laboratory; Suszcynsky, David M [Los Alamos National Laboratory; Hamlin, Timothy E [Los Alamos National Laboratory; Jeffery, C A [Los Alamos National Laboratory; Wiens, Kyle C [TEXAS TECH U.; Orville, R E [TEXAS A& M


    Los Alamos National Laboratory (LANL) owns and operates an array of Very-Low Frequency (VLF) sensors that measure the Radio-Frequency (RF) waveforms emitted by Cloud-to-Ground (CG) and InCloud (IC) lightning. This array, the Los Alamos Sferic Array (LASA), has approximately 15 sensors concentrated in the Great Plains and Florida, which detect electric field changes in a bandwidth from 200 Hz to 500 kHz (Smith et al., 2002). Recently, LANL has begun development of a new dual-band RF sensor array that includes the Very-High Frequency (VHF) band as well as the VLF. Whereas VLF lightning emissions can be used to deduce physical parameters such as lightning type and peak current, VHF emissions can be used to perform precise 3d mapping of individual radiation sources, which can number in the thousands for a typical CG flash. These new dual-band sensors will be used to monitor lightning activity in hurricanes in an effort to better predict intensification cycles. Although the new LANL dual-band array is not yet operational, we have begun initial work utilizing both VLF and VHF lightning data to monitor hurricane evolution. In this paper, we present the temporal evolution of Rita's landfall using VLF and VHF lightning data, and also WSR-88D radar. At landfall, Rita's northern eyewall experienced strong updrafts and significant lightning activity that appear to mark a transition between oceanic hurricane dynamics and continental thunderstorm dynamics. In section 2, we give a brief overview of Hurricane Rita, including its development as a hurricane and its lightning history. In the following section, we present WSR-88D data of Rita's landfall, including reflectivity images and temporal variation. In section 4, we present both VHF and VLF lightning data, overplotted on radar reflectivity images. Finally, we discuss our observations, including a comparison to previous studies and a brief conclusion.

  13. Estimating the human influence on Hurricanes Harvey, Irma and Maria (United States)

    Wehner, M. F.; Patricola, C. M.; Risser, M. D.


    Attribution of the human-induced climate change influence on the physical characteristics of individual extreme weather events has become an advanced science over the past decade. However, it is only recently that such quantification of anthropogenic influences on event magnitudes and probability of occurrence could be applied to very extreme storms such as hurricanes. We present results from two different classes of attribution studies for the impactful Atlantic hurricanes of 2017. The first is an analysis of the record rainfall amounts during Hurricane Harvey in the Houston, Texas area. We analyzed observed precipitation from the Global Historical Climatology Network with a covariate-based extreme value statistical analysis, accounting for both the external influence of global warming and the internal influence of ENSO. We found that human-induced climate change likely increased Hurricane Harvey's total rainfall by at least 19%, and likely increased the chances of the observed rainfall by a factor of at least 3.5. This suggests that changes exceeded Clausius-Clapeyron scaling, motivating attribution studies using dynamical climate models. The second analysis consists of two sets of hindcast simulations of Hurricanes Harvey, Irma, and Maria using the Weather Research and Forecasting model (WRF) at 4.5 km resolution. The first uses realistic boundary and initial conditions and present-day greenhouse gas forcings while the second uses perturbed conditions and pre-industrial greenhouse has forcings to simulate counterfactual storms without anthropogenic influences. These simulations quantify the fraction of Harvey's precipitation attributable to human activities and test the super Clausius-Clapeyron scaling suggested by the observational analysis. We will further quantify the human influence on intensity for Harvey, Irma, and Maria.

  14. Race differences in depression vulnerability following Hurricane Katrina. (United States)

    Ali, Jeanelle S; Farrell, Amy S; Alexander, Adam C; Forde, David R; Stockton, Michelle; Ward, Kenneth D


    This study investigated whether racial disparities in depression were present after Hurricane Katrina. Data were gathered from 932 New Orleans residents who were present when Hurricane Katrina struck, and who returned to New Orleans the following year. Multiple logistic regression models evaluated racial differences in screening positive for depression (a score ≥16 on the Center for Epidemiologic Studies Depression Scale), and explored whether differential vulnerability (prehurricane physical and mental health functioning and education level), differential exposure to hurricane-related stressors, and loss of social support moderated and/or reduced the association of race with depression. A univariate logistic regression analysis showed the odds for screening positive for depression were 86% higher for African Americans than for Caucasians (odds ratio [OR] = 1.86 [1.28-2.71], p = .0012). However, after controlling simultaneously for sociodemographic characteristics, preexisting vulnerabilities, social support, and trauma-specific factors, race was no longer a significant correlate for screening positive for depression (OR = 1.54 [0.95-2.48], p = .0771). The racial disparity in postdisaster depression seems to be confounded by sociodemographic characteristics, preexisting vulnerabilities, social support, and trauma-specific factors. Nonetheless, even after adjusting for these factors, there was a nonsignificant trend effect for race, which could suggest race played an important role in depression outcomes following Hurricane Katrina. Future studies should examine these associations prospectively, using stronger assessments for depression, and incorporate measures for discrimination and segregation, to further understand possible racial disparities in depression after Hurricane Katrina.

    B. Rojo-Garibaldi


    Full Text Available Hurricanes are complex systems that carry large amounts of energy. Their impact often produces natural disasters involving the loss of human lives and materials, such as infrastructure, valued at billions of US dollars. However, not everything about hurricanes is negative, as hurricanes are the main source of rainwater for the regions where they develop. This study shows a nonlinear analysis of the time series of the occurrence of hurricanes in the Gulf of Mexico and the Caribbean Sea obtained from 1749 to 2012. The construction of the hurricane time series was carried out based on the hurricane database of the North Atlantic basin hurricane database (HURDAT and the published historical information. The hurricane time series provides a unique historical record on information about ocean–atmosphere interactions. The Lyapunov exponent indicated that the system presented chaotic dynamics, and the spectral analysis and nonlinear analyses of the time series of the hurricanes showed chaotic edge behavior. One possible explanation for this chaotic edge is the individual chaotic behavior of hurricanes, either by category or individually regardless of their category and their behavior on a regular basis.

  20. Interactive voxel graphics in virtual reality (United States)

    Brody, Bill; Chappell, Glenn G.; Hartman, Chris


    Interactive voxel graphics in virtual reality poses significant research challenges in terms of interface, file I/O, and real-time algorithms. Voxel graphics is not so new, as it is the focus of a good deal of scientific visualization. Interactive voxel creation and manipulation is a more innovative concept. Scientists are understandably reluctant to manipulate data. They collect or model data. A scientific analogy to interactive graphics is the generation of initial conditions for some model. It is used as a method to test those models. We, however, are in the business of creating new data in the form of graphical imagery. In our endeavor, science is a tool and not an end. Nevertheless, there is a whole class of interactions and associated data generation scenarios that are natural to our way of working and that are also appropriate to scientific inquiry. Annotation by sketching or painting to point to and distinguish interesting and important information is very significant for science as well as art. Annotation in 3D is difficult without a good 3D interface. Interactive graphics in virtual reality is an appropriate approach to this problem.

  1. Graphical calculus for Gaussian pure states

    International Nuclear Information System (INIS)

    Menicucci, Nicolas C.; Flammia, Steven T.; Loock, Peter van


    We provide a unified graphical calculus for all Gaussian pure states, including graph transformation rules for all local and semilocal Gaussian unitary operations, as well as local quadrature measurements. We then use this graphical calculus to analyze continuous-variable (CV) cluster states, the essential resource for one-way quantum computing with CV systems. Current graphical approaches to CV cluster states are only valid in the unphysical limit of infinite squeezing, and the associated graph transformation rules only apply when the initial and final states are of this form. Our formalism applies to all Gaussian pure states and subsumes these rules in a natural way. In addition, the term 'CV graph state' currently has several inequivalent definitions in use. Using this formalism we provide a single unifying definition that encompasses all of them. We provide many examples of how the formalism may be used in the context of CV cluster states: defining the 'closest' CV cluster state to a given Gaussian pure state and quantifying the error in the approximation due to finite squeezing; analyzing the optimality of certain methods of generating CV cluster states; drawing connections between this graphical formalism and bosonic Hamiltonians with Gaussian ground states, including those useful for CV one-way quantum computing; and deriving a graphical measure of bipartite entanglement for certain classes of CV cluster states. We mention other possible applications of this formalism and conclude with a brief note on fault tolerance in CV one-way quantum computing.

    CERN Document Server

    Enderle, G


    Computer graphics methods and tools are being used to a great extent in scientific research. The future development in this area will be influenced both by new hardware developments and by software advances. On the hardware sector, the development of the raster technology will lead to the increased use of colour workstations with more local processing power. Colour hardcopy devices for creating plots, slides, or movies will be available at a lower price than today. The first real 3D-workstations will appear on the marketplace. One of the main activities on the software sector is the standardization of computer graphics systems, graphical files, and device interfaces. This will lead to more portable graphical application programs and to a common base for computer graphics education.

  6. Graphical Model Theory for Wireless Sensor Networks

    International Nuclear Information System (INIS)

    Davis, William B.


    Information processing in sensor networks, with many small processors, demands a theory of computation that allows the minimization of processing effort, and the distribution of this effort throughout the network. Graphical model theory provides a probabilistic theory of computation that explicitly addresses complexity and decentralization for optimizing network computation. The junction tree algorithm, for decentralized inference on graphical probability models, can be instantiated in a variety of applications useful for wireless sensor networks, including: sensor validation and fusion; data compression and channel coding; expert systems, with decentralized data structures, and efficient local queries; pattern classification, and machine learning. Graphical models for these applications are sketched, and a model of dynamic sensor validation and fusion is presented in more depth, to illustrate the junction tree algorithm

  7. CT applications of medical computer graphics

    International Nuclear Information System (INIS)

    Rhodes, M.L.


    Few applications of computer graphics show as much promise and early success as that for CT. Unlike electron microscopy, ultrasound, business, military, and animation applications, CT image data are inherently digital. CT pictures can be processed directly by programs well established in the fields of computer graphics and digital image processing. Methods for reformatting digital pictures, enhancing structure shape, reducing image noise, and rendering three-dimensional (3D) scenes of anatomic structures have all become routine at many CT centers. In this chapter, the authors provide a brief introduction to computer graphics terms and techniques commonly applied to CT pictures and, when appropriate, to those showing promise for magnetic resonance images. Topics discussed here are image-processing options that are applied to digital images already constructed. In the final portion of this chapter techniques for ''slicing'' CT image data are presented, and geometric principles that describe the specification of oblique and curved images are outlined. Clinical examples are included

A reading room has been converted to a research computer lab by adding some furniture and an air conditioning unit in order to provide an appropriate working environments for researchers and the purchase equipment. All the purchased equipment were successfully installed and are fully functional. Several research projects, including two existing Air Force projects, are being performed using these facilities.

  9. Design considerations for parallel graphics libraries (United States)

    Crockett, Thomas W.


    Applications which run on parallel supercomputers are often characterized by massive datasets. Converting these vast collections of numbers to visual form has proven to be a powerful aid to comprehension. For a variety of reasons, it may be desirable to provide this visual feedback at runtime. One way to accomplish this is to exploit the available parallelism to perform graphics operations in place. In order to do this, we need appropriate parallel rendering algorithms and library interfaces. This paper provides a tutorial introduction to some of the issues which arise in designing parallel graphics libraries and their underlying rendering algorithms. The focus is on polygon rendering for distributed memory message-passing systems. We illustrate our discussion with examples from PGL, a parallel graphics library which has been developed on the Intel family of parallel systems.

    This article examines graphic design’s role within design activism. It outlines design activism in general and its relation to commercial design culture in a consumerist economy. Thereafter it discusses persuasive tendencies in graphic design and questions if its current contribution to design...... activism is limited to its predominant narrow role of persuading for “the good cause.” To illustrate the hypothesis that such a persuasive approach lacks activist potential and thus social impact, cases that represent traditional graphic-design activism are compared to alternative approaches...... solely solving communicative problems for commissioning clients. It is argued that in this way visual communication can intervene into problems on a functional level, similarly to artifacts from design disciplines such as architecture and industrial or product design....

  11. Network performance for graphical control systems

    International Nuclear Information System (INIS)

    Clout, P.; Geib, M.; Westervelt, R.


    Vsystem is a toolbox for building graphically-based control systems. The real-tiem database component, Vaccess, includes all the networking support necessary to build multi-computer control systems. Vaccess has two modes of database access, synchronous and asynchronous. Vdraw is another component of Vsystem that allows developers and users to develop control screens and windows by drawing rather than programming. Based on X-windows, Vsystem provides the possibility of running Vdraw either on the workstation with the graphics or on the computer with the database. We have made some measurements on the cpu loading, elapsed time and the network loading to give some guidance in system configuration performance. It will be seen that asynchronous network access gives large performance increases and that the network database change notification protocol can be either more or less efficient than the X-window network protocol, depending on the graphical representation of the data.

    M. J. Mišić


    Full Text Available Graphics processing units (GPUs have been increasingly used for general-purpose computation in recent years. The GPU accelerated applications are found in both scientific and commercial domains. Sorting is considered as one of the very important operations in many applications, so its efficient implementation is essential for the overall application performance. This paper represents an effort to analyze and evaluate the implementations of the representative sorting algorithms on the graphics processing units. Three sorting algorithms (Quicksort, Merge sort, and Radix sort were evaluated on the Compute Unified Device Architecture (CUDA platform that is used to execute applications on NVIDIA graphics processing units. Algorithms were tested and evaluated using an automated test environment with input datasets of different characteristics. Finally, the results of this analysis are briefly discussed.

  14. Visualization of graphical information fusion results (United States)

    Blasch, Erik; Levchuk, Georgiy; Staskevich, Gennady; Burke, Dustin; Aved, Alex


    Graphical fusion methods are popular to describe distributed sensor applications such as target tracking and pattern recognition. Additional graphical methods include network analysis for social, communications, and sensor management. With the growing availability of various data modalities, graphical fusion methods are widely used to combine data from multiple sensors and modalities. To better understand the usefulness of graph fusion approaches, we address visualization to increase user comprehension of multi-modal data. The paper demonstrates a use case that combines graphs from text reports and target tracks to associate events and activities of interest visualization for testing Measures of Performance (MOP) and Measures of Effectiveness (MOE). The analysis includes the presentation of the separate graphs and then graph-fusion visualization for linking network graphs for tracking and classification.

  15. Graphic medicine: comics as medical narrative. (United States)

    Williams, Ian C M


    Among the growing number of works of graphic fiction, a number of titles dealing directly with the patient experience of illness or caring for others with an illness are to be found. Thanks in part to the Medical Humanities movement, many medical schools now encourage the reading of classic literature to gain insight into the human condition. Until recently, the medium of comics (the term is used in the plural to refer to both the physical objects and the attendant philosophy and practice surrounding them) has received little attention from healthcare scholars, even though some authors argue that graphic fiction is, in fact, a form of literature. This paper suggests that it is time that the medium was examined by healthcare professionals and studies some acclaimed comic works. Drawing on the principles of narrative medicine, this paper will ask whether comics and graphic novels could be used as a resource for health professionals, patients and carers.

  17. Interactive computer graphics applications for compressible aerodynamics (United States)

    Benson, Thomas J.


    Three computer applications have been developed to solve inviscid compressible fluids problems using interactive computer graphics. The first application is a compressible flow calculator which solves for isentropic flow, normal shocks, and oblique shocks or centered expansions produced by two dimensional ramps. The second application couples the solutions generated by the first application to a more graphical presentation of the results to produce a desk top simulator of three compressible flow problems: 1) flow past a single compression ramp; 2) flow past two ramps in series; and 3) flow past two opposed ramps. The third application extends the results of the second to produce a design tool which solves for the flow through supersonic external or mixed compression inlets. The applications were originally developed to run on SGI or IBM workstations running GL graphics. They are currently being extended to solve additional types of flow problems and modified to operate on any X-based workstation.

    Jeletic, James F.


    The application of computer graphics techniques in NASA space missions is reviewed. Telemetric monitoring of the Space Shuttle and its components is discussed, noting the use of computer graphics for real-time visualization problems in the retrieval and repair of the Solar Maximum Mission. The use of the world map display for determining a spacecraft's location above the earth and the problem of verifying the relative position and orientation of spacecraft to celestial bodies are examined. The Flight Dynamics/STS Three-dimensional Monitoring System and the Trajectroy Computations and Orbital Products System world map display are described, emphasizing Space Shuttle applications. Also, consideration is given to the development of monitoring systems such as the Shuttle Payloads Mission Monitoring System and the Attitude Heads-Up Display and the use of the NASA-Goddard Two-dimensional Graphics Monitoring System during Shuttle missions and to support the Hubble Space Telescope.
