    It is the nature of complex systems, composed of many interacting elements, that unanticipated phenomena develop. Computer simulation, in which the elements of a complex system are implemented as interacting software objects (actors), is an effective tool to study collective and emergent phenomena in complex systems. A new cognitive architecture is described for constructing simulation actors that can, like the intelligent elements they represent adapt to unanticipated conditions. This cognitive architecture generates trial behaviors, estimates their fitness using an internal representation of the system, and has an internal apparatus for evolving a population of trial behaviors to changing environmental conditions. A specific simulation actor is developed to evaluate surveillance radar images of moving vehicles on battlefields. The vehicle cluster location, characterization and discrimination processes currently performed by intelligent human operators were implemented into a parameterized formation recognition process by using a newly developed family of 2D cluster filters. The mechanics of these cluster filters are described. Preliminary results are presented in which this GSM actor demonstrates the ability not only to recognize military formations under prescribed conditions, but to adapt its behavior to unanticipated conditions that develop in the complex simulated battlefield system.

    This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). This project involved research in the area of warfighting simulation technology and methods. In the first year our emphasis was to produce a prototype repository for simulation software objects and simulation execution executives in the context of an integrated theater missile defense problem. This provided a necessary precursor to the detailed development. In the second year more detailed and complete environments. In the second year more detailed and complete development of composable simulation software was undertaken. An object description language was developed, an object composition architecture was developed and implemented, and a prototyping test bed was produced to assess the technical concepts and as a demonstration tool for programmatic activities. In the third and final year it became apparent that the representation of intelligent entities, specifically those that fulfill command and control functions in warfighting systems, was a challenging and serious technical shortcoming of all existing approaches to simulation of warfare. 10 refs.

    A numeric model has been developed to identify the critical components and parameters in improving the output beam quality of a flashlamp pumped Q-switched Nd:YAG laser with a folded Porro-prism resonator and polarization output coupling. The heating of the laser material and accompanying thermo-optical effects are calculated using the finite element partial differential equations package FEMLAB allowing arbitrary geometries and time distributions. The laser gain and the cavity are modeled with the physical optics simulation code GLAD including effects such as gain profile, thermal lensing and stress-induced birefringence, the Pockels cell rise-time and component aberrations. The model is intended to optimize the pumping process of an OPO providing radiation to be used for ranging, imaging or optical countermeasures.

    The army's combat training is very important now, and the simulation of the real battlefield environment is of great significance. Two-dimensional information has been unable to meet the demand at present. With the development of virtual reality technology, three-dimensional (3D) simulation of the battlefield environment is possible. In the simulation of 3D battlefield environment, in addition to the terrain, combat personnel and the combat tool ,the simulation of explosions, fire, smoke and other effects is also very important, since these effects can enhance senses of realism and immersion of the 3D scene. However, these special effects are irregular objects, which make it difficult to simulate with the general geometry. Therefore, the simulation of irregular objects is always a hot and difficult research topic in computer graphics. Here, the particle system algorithm is used for simulating irregular objects. We design the simulation of the explosion, fire, smoke based on the particle system and applied it to the battlefield 3D scene. Besides, the battlefield 3D scene simulation with the glasses-free 3D display is carried out with an algorithm based on GPU 4K super-multiview 3D video real-time transformation method. At the same time, with the human-computer interaction function, we ultimately realized glasses-free 3D display of the simulated more realistic and immersed 3D battlefield environment.

    The QuickStrike ASOC (Air Support Operations Center) Battlefield Simulation fills a crucial gap in USAF and United Kingdom Close Air Support (CAS) and airspace manager training. The system now provides six squadrons with the capability to conduct total-mission training events whenever the personnel and time are available. When the 111th ASOC returned from their first deployment to Afghanistan they realized the training available prior to deployment was inadequate. They sought an organic training capability focused on the ASOC mission that was low cost, simple to use, adaptable, and available now. Using a commercial off-the-shelf simulation, they developed a complete training system by adapting the simulation to their training needs. Through more than two years of spiral development, incorporating lessons learned, the system has matured, and can now realistically replicate the Tactical Operations Center (TOC) in Kabul, Afghanistan, the TOC supporting the mission in Iraq, or can expand to support a major conflict scenario. The training system provides a collaborative workspace for the training audience and exercise control group via integrated software and workstations that can easily adapt to new mission reqUirements and TOC configurations. The system continues to mature. Based on inputs from the war fighter, new capabilities have been incorporated to add realism and simplify the scenario development process. The QuickStrike simulation can now import TBMCS Air Tasking Order air mission data and can provide air and ground tracks to a common operating picture; presented through either C2PC or JADOCS. This oranic capability to practice team processes and tasks and to conduct mission rehearsals proved its value in the 111 h ASOS's next deployment. The ease of scenario development and the simple to learn and intuitive gamelike interface enables the squadrons to develop and share scenarios incorporating lessons learned from every deployment. These war fighters have now

    2017-05-01

    The work presented within examines the performance of mechanical and electronic anemometers in battlefield applications. The goals of the study were to determine the utility of a local anemometer in quasi-combat engagements for direct fire weapon systems, to observe the limitations of each type of anemometer, and to determine which measurement method results in the most accurate ballistic correction. These goals are accomplished by combining a ballistic trajectory model, a turbulent wind field model, a sensor response model, and a fire control model into a single larger scale simulation that utilizes a Monte Carlo approach. The results of this effort showed that utilizing either a mechanical anemometer or an electronic anemometer with a relatively long averaging window produced the most accurate ballistic wind correction.

As a important part of it, simulation of distributed virtual naval battlefield has to account for real-time simulation of ocean wave in wide area and delaying of network in larger data. Based on statistical wave models, a view dependent LOD model is proposed to realize a multiple level of detail modeling of ocean wave, and improved the real time and fidelity. As a further work, based on the Winsock TCP/IP protocol and using technology of multicasting and Dead Reckoning ( DR) , it decreases the data of distributed virtual naval battlefield and realizes a multi-channel view mosaic in several PC. The test shows the effectiveness of the work.

  10. Military Healthcare Battlefield Immunity.

    Science.gov (United States)

    Kelly, J C

    2012-12-01

    The combatant soldier on the battlefield remains protected from any claim in negligence by the doctrine of combat immunity for any negligent act or omission they may make when fighting. In other words, the combatant soldier does not owe a fellow soldier a duty of care on the battlefield, as the duty of care is non-justiciable. However, the non-combatant Military Healthcare Professional, although sometimes operating in the same hostile circumstances as the fighting soldier, is unlikely to benefit from combat immunity for any clinical negligence on the battlefield. This is because they continue to owe their patient a duty of care, although this has not been tested in the courts. This paper considers if any military healthcare professional could ever benefit from combat immunity, which is unlikely due to their non-combatant status. Instead, this paper suggests that a modified form of immunity; namely, Military Healthcare Battlefield Immunity could be a new, unique and viable doctrine, however, this could only be granted in rare circumstances and to a much lesser degree than combat immunity.

    An extensible network simulation application was developed to study wireless battlefield communications. The application monitors node mobility and depicts broadcast and unicast traffic as expanding rings and directed links. The network simulation was specially designed to support fault injection to show the impact of air strikes on disabling nodes. The application takes standard ns-2 trace files as an input and provides for performance data output in different graphical forms (histograms and x/y plots). Network visualization via animation of simulation output can be saved in AVI format that may serve as a basis for a real-time battlefield awareness system.

  14. Battlefield spectrum management

    Sivakumar, C.

    1997-06-01

    Modern tactical communications systems rely on radios to support network and user connectivity. One of the challenges for network planners and managers is to make best use of scarce and vulnerable frequency spectrum resources to support the communication needs of war fighters. With the wide variety of Iris radio types typically to be deployed in the battlefield (ranging from high frequency to super high frequency), a comprehensive suite of tools is necessary to ensure that frequency interference is kept minimum. Without a sophisticated frequency spectrum management system, the most advanced tactical communications systems could be rendered useless, jeopardizing human life and national security. For these reasons, it is important to develop an Iris wide battlefield spectrum management capability that takes full advantage of current frequency spectrum management research and development (R&D), related tools, and supporting technology for assigning frequencies. This session briefly describes various assignment strategies being adopted in the Iris BFSM for overcoming cosite/collocated/farsite interferences along with the propagation models [from high frequency (HF) to super high frequency (SHF)] used for the assignment of frequencies. Also a brief thread outlining the process for generating frequency allocation/assignment request and analysis of frequency interference is discussed.

  1. Battlefield euthanasia - courageous compassion or war crime?

    Science.gov (United States)

    Neuhaus, Susan J

    2011-03-21

    Issues relating to voluntary euthanasia that are currently being debated by Australian society are distinctly different from those encountered by battlefield doctors. Doctors in war undertake to treat those affected by conflict; their participation in euthanasia challenges the profession's definition of "duty of care". Euthanasia must be distinguished from "triage" and medical withdrawal of care (which are decided within a medical facility where, although resources may be limited, comfort care can be provided in the face of treatment futility). Battlefield euthanasia is a decision made, often immediately after hostile action, in the face of apparently overwhelming injuries; there is often limited availability of pain relief, support systems or palliation that would be available in a civilian environment. The battlefield situation is further complicated by issues of personal danger, the immediacy of decision making and difficulties with distinguishing civilians from combatants. Regardless of the circumstances on a battlefield, doctors, whether they are civilians or members of a defence force, are subject to the laws of armed conflict, the special provisions of the Geneva Conventions and the ethical codes of the medical profession.

  2. Resource Dependent Radio Allocation For Battlefield Communications - A Data Model Approach

    Directory of Open Access Journals (Sweden)

    Gregor Thomeczek

    2014-10-01

    Full Text Available Network Enabled Capability (NEC and the Land Open Systems Architecture (LOSA are novel approaches to enable interoperability between a heterogeneous collection of assets in the battlefield. These paradigms utilise an underlying network for cooperation between deployed battlefield equipment. NEC and LOSA have great potential to transform military communications and enhance integrated survivability as well as situational awareness, but the Achilles’ heel of NEC and LOSA is the wireless spectrum over which they must communicate. A noisy and dynamic battlefield wireless spectrum as well as an array of heterogeneous wireless communications equipment handling multiple types of data with different Quality of Service (QoS requirements requires a system which manages and allocates these communication resources effectively. This paper presents the High Availability Wireless Communications (HAWC system, a hardware agnostic communications controller middleware to manage any combination of existing and future multiband wireless resources. The system utilises a vehicle’s data model to gather information about available radio resources and enable LOSA by meeting communications data requirements and delivering appropriate QoS to the appropriate traffic in a fleet of vehicles. The functionality of the system is verified by using behavioural simulation on a virtual battlefield.

    Bremner, Luke F; Mazurek, Michael

    2010-01-01

    Throughout our current conflicts in both Iraq and Afghanistan, the likelihood of surviving a battlefield injury has been near 90% according to reports provided by the US Army Medical Research and Materiel Command. This is the highest survival rate recorded in modern combat. Advancements in protective equipment, rapid evacuation of casualties from point of injury to both stabilization and definitive care, improved medic and corpsmen personnel, more readily available resuscitation, and forward positioned surgical units have all significantly decreased troop mortality. Along with this phenomenon of increased survival, however, has come a surge in the number and significance of injuries seen by the medical community. As a result, orthopaedists have been forced to confront reconstructive challenges and difficult decisions in an often highly motivated patient population with high functional expectations. The objective of this article is to outline a few examples of difficult challenges encountered in battlefield trauma care and discuss the treatments utilized.

    2008-04-01

    Getting to wounded soldiers on the battlefield is a precarious task, and medics have a very high casualty rate. It is therefore a vital importance to prioritize which soldiers to attend to first. The first step is to detect life signs - if a soldier is dead or alive, and prioritize recovery of live soldiers. The second step is to obtain vital signs from live soldiers, and use this to prioritize which are in most urgent need of attention. Our team at Kai Sensors, University of Hawaii and University of Florida is developing Doppler radar heart sensing technology that provides the means to detect life signs, respiration and/or heart beat, at a distance, even for subjects lying motionless, e.g., unconscious subjects, wearing body armor, and hidden from direct view. Since this technology can deliver heart rate information with high accuracy, it may also enable the assessment of a subject's physiological and psychological state based on heart rate variability (HRV) analysis. Thus, the degree of a subject's injury may also be determined. The software and hardware developments and challenges for life signs detection and monitoring for battlefield triage will be discussed, including heart signal detection from all four sides of the human body, detection in the presence of body armor, and the feasibility of HRV parameter extraction.

  5. Trauma management on the battlefield: a modern approach.

    Science.gov (United States)

    Hawley, A

    1996-10-01

    With the development of British Army doctrine it is necessary to review the concepts underlying medical support to the modern battlefield. In particular, the provision of timely and balanced resuscitation to the high intensity battle is an issue requiring an understanding of both the tactical and the clinical demands. The wholesale application of civilian techniques and approaches to trauma management is not possible given the austerity of the battlefield clinical environment. The commitment to excellence and quality of care implicit in modern mainstream practice is of continuing relevance to the battlefield. A doctrinal approach involving the definition of desired clinical outcome and the constraints of operational feasibility, is proposed. Specifically, the introduction of a triad approach to trauma management is offered. The triad comprises readily available Battlefield Advanced Trauma Life Support (BATLS) skills, Surgical Resuscitation deployed forward and the provision of Field Intensive Care. Such an approach would marry together the clinically ideal with the tactically.

    In current military operations, the survival rates of critically injured casualties are unprecedented. An often hidden aspect of casualty care is safe transport from the point of injury to a field hospital and subsequently on to higher levels of care. This en route critical care, which is provided by flight medics under the most austere and rigorous conditions, is a crucial link in the care continuum. This article introduces the role and capabilities of US Army MEDEVAC and reflects the author's recent experience in Afghanistan as a flight medic. This article provides an assessment of the operational issues, medical capabilities, and transport experiences to provide a real-world view of critical care transport from the battlefield. The MEDEVAC helicopter environment is one of the most difficult, if not the most demanding, critical care environments. This overview brings to light a small but important piece of the care continuum.

    Battlefield damage assessment is the key to Battlefield Damage Assessment and Repair (BDAR).We present an Intelligent Battlefield Damage Assessment System (IBDAS) based on multi-agent system technology. We first establish the system framework, and then study the interior structure and workflow of a problem allocation agent. The result shows that, there are many advantages to resolve the problem of battlefield damage assessment by applying multi-agent system technology, and it will bring significant military benefit.

  10. Battlefield conditions: different environment but the same duty of care.

    Using an interpretative research approach to ethical and legal literature, it is argued that nursing in the battlefield is distinctly different to civilian nursing, even in an emergency, and that the environment is so different that a duty of care owed by military nurses to wounded soldiers should not apply. Such distinct differences in wartime can override normal peacetime professional ethics to the extent that the duty of care owed by military nurses to their patients on the battlefield should not exist. It is also argued that as military nurses have legal and professional obligations to care for wounded soldiers on the battlefield, this obligation conflicts with following military orders, causing a dual loyalty conflict. This is because soldiers are part of the 'fighting force' and must be fit to fight and win the battle. This makes them more of a commodity rather than individual persons with distinct health care needs.

  11. Battlefield Acupuncture: Is It Ready for Widespread Dissemination?

    2017-01-01

    The use of prescription opioids for chronic pain has increased markedly within the past few decades; thus, death rates associated with opioid overdoses have increased dramatically. Nonopioid pharmacologic therapies also are associated with adverse effects. Other pain-abatement modalities such as acupuncture may be useful in the treatment of several painful conditions. Battlefield acupuncture is being promulgated as a potential low-risk, nonpharmacological therapy for pain. In this narrative review we examine the published literature to support battlefield acupuncture. We conclude that the amount and quality of published research presently do not justify wide adoption of this practice by those strictly adherent to evidence-based medicine.

    Full Text Available The purpose of this article is to present the findings from a collaborative study conducted by a research team consisting of university students and a course instructor visiting battlefields and memorials located in Western Europe. The goal of the course was to provide students with an experiential opportunity to learn about the First and Second World Wars, acquire insights into the management of battlefields, memorials and museums, participate in video interviews, and administer surveys on-site. Emphasizing the field component of the course, this paper discusses how visual ethnography can be used to provide a greater understanding of visitor motivations and enhanced tourism learning experiences. Also discussed are the strengths and weaknesses of conducting field research for a university undergraduate level course and the potential contributions that such approaches bring to learning and memory.

    Like the wars predating the First World War where human foot soldiers were deemed tools in the battlefield against an enemy, so too are the host immune cells of a patient battling a malignant gastric cancer. Indeed, the tumour microenvironment resembles a battlefield, where the patient’s immune cells are the defence against invading tumour cells. However, the relationship between different immune components of the host response to cancer is more complex than an “us against them” model. Components of the immune system inadvertently work against the interests of the host and become pro-tumourigenic while other components soldier on against the common enemy – the tumour cell.

    2010-12-01

    Full Text Available Archaeological investigations have been taking place at the Kalkriese Hill in Northern Germany since 1987. Roman coins and military equipment are the result of a battle between Romans and Germans, probably the Varus Battle (A.D. 9. It is the aim of our research project to reconstruct the course of the battle. It has become apparent that one cannot deduct the intensity of fighting by the number of finds. Instead, we have to take into account the impact of post-battle processes on the archaeological record, such as rescuing of wounded soldiers, looting by the victors and body-stripping. This paper illustrates the finds and features from Kalkriese, especially from the main site «Oberesch», where most of the Roman artefacts as well as a rampart built by Germans as an ambush against Roman troops, and a series of pits containing the bones of the dead Roman soldiers were found. In addition, new methodological approaches for the interpretation of ancient battlefields are presented.

    Desde 1987 se vienen realizando investigaciones arqueológicas en la colina de Kalkriese, en Alemania septentrional. El hallazgo de monedas y equipo militar romanos refleja una batalla entre romanos y germanos, probablemente la de Varo en el año 9 d.C. El propósito de nuestro proyecto de investigación es reconstruir el curso de la batalla. Se hace evidente que no se puede deducir la intensidad de la lucha por el número de hallazgos. Por el contrario, hemos de tener muy en cuenta los procesos posteriores a la batalla sobre el registro arqueológico, como el rescate de soldados heridos, la captura de botín por parte de los vencedores y el saqueo de los cadáveres. Este trabajo ilustra los hallazgos y las caractertísticas del yacimiento de Kalkriese, especialmente en el núcleo del ‘Oberesch’, donde se ha hallado la mayor parte de los artefactos romanos, además de una empalizada construida por los germanos para emboscar a los romanos, y una serie de hoyos que

    Full Text Available In the UK battlefields are becoming more frequently associated with the label 'heritage at risk'. As the concept of battlefield and conflict archaeology has evolved, so too has the recognition that battlefields are dynamic, yet fragile, archaeological landscapes in need of protection. The tangible evidence of battle is primarily identified by distributions of artefacts held within the topsoil, such as lead projectiles, weapon fragments or buttons torn from clothing; debris strewn in the heat of battle. Much of the battlefield therefore remains as a faint footprint and, where it survives, may provide valuable information, if recorded accurately. The unrecorded removal of artefacts from battlefields and other sites of conflict is a key issue in the management and conservation of this unique archaeological heritage. With a particular focus on current doctoral research, this paper aims to address the role of metal detecting in the UK as an important factor in this equation, having both a positive and negative impact on battlefield archaeology. Furthermore it will also consider the nature of metal detecting on UK battlefields; the perceived value of battle-related artefacts; the quality of information available for recording material from such sites, and what may co-operatively be achieved.

    The famous battle of Chibi,or "battle of Red Cliff",took place in 208 CE,the 13th year of the Jian'an period of the Eastern Han dynasty.This paper holds that the whole battle consisted of three inseparable stages,namely the initial clash at Chibi,the chase battle to Wulin,and Cao Cao's disorganized escape along Huarong Road.The Red Cliff battlefield thus extended across a distance of more than 300 li (150km).Even if the Chibi where the initial military engagement took place (that is,Chiji Hill,southwest of Wuchang in modern Wuhan City) has already disappeared,it should be restored to its proper historical position.The chase battle along the Yangzi River came to an end at Wulin,across the river is Chibi Hill in today's Chibi City.Although this Chibi is not the Chibi where the initial combat took place,it nonetheless forms an integral part of the ancient Chibi battlefield as a whole.The Huarong Road along which Cao Cao escaped runs through the middle of today's Jianghan Plain.Finally,the text aims to show that Chibi (Red Nose)1 Hill in modern Huangzhou City has nothing to do with the Chibi of the "battle of Red Cliff."

    Wars previously being executed at land and sea have also become applicable in air and space due to the advancements of aircraft and satellite systems. Rapid improvements in information technologies have triggered the concept of cyberspace which is considered as the fifth dimension of war. While transferring information quickly from physical area to electronic/digital area, cyberspace has caused to emerge a lot of threats and methods like cyber-attack, cyber-crime, cyber war which are spreading too rapidly. Individuals, institutions and establishments have begun to take their own cyber security precautions to cope with these threats. This study gives information about the concepts and advances on cyberspace in order to raise comprehensive awareness. The study also focuses on the effects of these improvements in the battlefield, and analyzes them.

    空间战场目标威胁评估对未来空间作战指挥决策具有重要的意义,探讨了空间战场的特点及空间战场威胁目标的特点.针对静态贝叶斯网络(Bayesian network,BN)无法有效地解决动态空间战场中目标的威胁评估问题,提出利用动态贝叶斯网络(dynamic Bayesian network,DBN)来解决空间战场目标威胁评估,建立了基于DBN的空间战场目标威胁评估模型,利用所建立的模型进行了仿真计算.研究结果证明,基于DBN的空间战场目标威胁评估模型能够适应战场形势的变化,可应用于未来空间战场目标威胁评估专家系统的开发,并且比利用静态BN得出的威胁程度更准确,可靠性更高.%Threat assessment of space battlefield targets has great meaning for command and decision-making in the future space operation. The paper discusses the characteristics of space battlefield and space threat targets. Aiming at the problem of threat assessment that is not well solved by Bayes-ian network (BN) in the dynamic space battlefield, a dynamic Bayesian network (DBN) theory is introduced. After that, a DBN-based threat assessment model for space operation is constructed; then, the paper performs a simulation using the proposed model. The simulation result shows that the DBN-based threat assessment model is adaptive to the dynamic change in the battlefield; it can be used in the process of developing the expert system in the future space operation. What is more, the DBN-- based threat assessment model is more effective and reliable to reflect the real threat level than the Bayesian network model.

    2012-06-01

    While cyberspace is emerging as a new battlefield, conventional Electronic Warfare (EW) methods and applications are likely to change. Cyber Electronic Warfare (CEW) concept which merges cyberspace capabilities with traditional EW methods, is a new and enhanced form of the electronic attack. In this study, cyberspace domain of the battlefield is emphazised and the feasibility of integrating Cyber Warfare (CW) concept into EW measures is researched. The SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis method is used to state the operational advantages of using CEW concept in the battlefield. The operational advantages of CEW are assessed by means of its effects on adversary air defense systems, communication networks and information systems. Outstanding technological and operational difficulties are pointed out as well. As a result, a comparison of CEW concept and conventional EW applications is presented. It is concluded that, utilization of CEW concept is feasible at the battlefield and it may yield important operational advantages. Even though the computers of developed military systems are less complex than normal computers, they are not subjected to cyber threats since they are closed systems. This concept intends to show that these closed systems are also open to the cyber threats. As a result of the SWOT analysis, CEW concept provides Air Forces to be used in cyber operations effectively. On the other hand, since its Collateral Damage Criteria (CDC) is low, the usage of cyber electronic attack systems seems to grow up.

    2010-03-01

    Full Text Available During the last four decades or so, there has been an explosive growth in commercial, industrial, medical, scientific, technological, and above all, military usage of laser devices and systems. In fact, lasers have influenced every conceivable area of application during this period. While the expansion of non-military application spectrum of lasers is primarily driven by emergence of a large number of laser wavelengths followed by ever increasing power levels and reducing price tags at which those wavelengths could be generated, the military applications of lasers and related electro-optic devices have grown mainly because of technological maturity of the lasers that were born in the late 1960's and the early 1970's. Lasers have been used in various military applications since the early days of development that followed the invention of this magical device. There has been large scale proliferation of lasers and opto-electronic devices and systems for applications like range finding, target designation, target acquisition and tracking, precision guided munitions, etc. during 1970's and 1980's. These devices continue to improve in performance and find increased acceptance and usage in the contemporary battlefield scenario. Technological advances in optics, opto-electronics, and electronics, leading to more rugged, reliable, compact and efficient laser devices are largely responsible for making these indispensable in modern warfare. Past one decade or so has seen emergence of some new potential areas of usage. Some of these areas include rapid growth in the usage of lasers and opto-electronics devices and systems for electrooptic countermeasure (EOCM applications, test and evaluation systems that can perform online functionality checks on military opto-electronics systems and also their interoperability. In this paper, an overview of the current and emerging military applications of lasers and opto-electronics systems has been given with an outline

    2009-12-01

    The US military forces developed and implemented the Joint Theater Trauma System (JTTS) and Joint Theater Trauma Registry (JTTR) using US civilian trauma system models with the intent of improving outcomes after battlefield injury. The purpose of this analysis was to elaborate the impact of the JTTS. To quantify these achievements, the JTTR captured mechanism, acute physiology, diagnostic, therapeutic, and outcome data on 23,250 injured patients admitted to deployed US military treatment facilities from July 2003 through July 2008 for analysis. Comparative analysis to civilian trauma systems was done using the National Trauma Data Bank (NTDB). In contrast to civilian trauma systems with an 11.1% rate of penetrating injury, 68.3% of battlefield wounds were by penetrating mechanism. In the analyzed cohort, 23.3% of all patients had an Injury Severe Score (ISS) > or = 16, which is similar to the civilian rate of 22.4%. In the military injury population, 66% of injuries were combat-related. In addition, in the military injury group, 21.8% had metabolic evidence of shock with a base deficit > or = 5, 29.8% of patients required blood transfusion, and 6.4% of the total population of combat casualties required massive transfusion (>10 U red blood cells/24 hours). With this complex and severely injured population of battlefield injuries, the JTTS elements were used to recognize and remedy more than 60 trauma system issues requiring leadership and advocacy, education, research, and alterations in clinical care. Of particular importance to the trauma system was the implementation and tracking of performance improvement indicators and the dissemination of 27 evidence-based clinical practice guidelines (CPGs). In particular, the damage control resuscitation guideline was associated with a decrease in mortality in the massively transfused from 32% pre-CPG to 21% post-CPG. As evidence of the effectiveness of the JTTS, a mortality rate of 5.2% after battlefield hospital admission

    This study consists of work done in support of the U.S. delegation to the NATO SAS-023 Antipersonnel Landmine Study Group, supplemented by additional work done for the U.S. Office of the Secretary of Defense Antipersonnel Landmine Alternative Concept Exploration Program (Track III). It explores the battlefield utility of current antipersonnel landmines (APL) in both pure and mixed APL/antitank minefields and evaluates the value of military suggested non-materiel alternatives. The historical record is full of examples where the presence (or absence) of antipersonnel landmines made a critical difference in battle. The current generation of military thinkers and writers lack any significant combat experience employing either mixed or antipersonnel minefields, which leaves a critical gap in available expert advice for policy and decision-makers. Because of this lack of experienced-based professional military knowledge, Lawrence Livermore National Laboratory analyzed the employment of antipersonnel landmines in tactical mixed minefields and in protective antipersonnel minefields. The scientific method was employed where hypotheses were generated from the tactics and doctrine of the antipersonnel landmine era and tested in a simulation laboratory. A high-resolution, U.S. Joint Forces Command combat simulation model (the Joint Conflict and Tactical Simulation--JCATS) was used as the laboratory instrument. A realistic European scenario was obtained from a multi-national USAREUR exercise and was approved by the SAS-023 panel members. Additional scenarios were provided by U.S. CINC conferences and were based on Southwest Asia and Northeast Asia. Weapons data was obtained from the U.S. family of Joint Munitions Effectiveness Manuals. The U.S. Army Materiel Systems Analysis Agency conducted a limited verification and validation assessment of JCATS for purposes of this study.

  15. A Critique of the Militarisation of Australian History and Culture Thesis: The Case of Anzac Battlefield Tourism

    Directory of Open Access Journals (Sweden)

    Jim McKay

    2013-02-01

    Full Text Available This paper analyses the militarisation of Australian history and culture thesis with specific reference to the increasing popularity of Anzac battlefield tourism. I argue that the militarisation thesis contains ontological and epistemological flaws that render it incapable of understanding the multifaceted ways in which Australians experience Anzac battlefield tours. I then argue that in order to study how Australians both at home and overseas respond to the upcoming Anzac Centenary researchers will need to deploy an empirically-grounded and multidisciplinary framework. I demonstrate how proponents of militarisation: (1 ignore the polymorphous properties of Anzac myths; (2 are complicit with constructions of ‘moral panics’ about young Australian tourists; (3 overlook the reflexive capacities of teachers, students and tourists with respect to military history and battlefield tours; and (4 disregard the complex and contradictory aspects of visits to battlefields. My counter-narrative relies both on Stuart Hall’s work on popular culture and empirical studies of battlefield tourism from myriad disciplines.

    Battlefield stress is the consequence of man being exposed to the hostile environment of combat. Combat stress is specifically caused by man's feat of the dangers of combat, and is fueled and tempered by other variables such as morale, cohesion, fatigue, confidence, training and intensity of the combat. Treatment is often as simple as giving soldiers time to rest for a few hours or days, to get a shower and some sleep, to talk about the feelings they have in the presence of a counselor. Only in rare cases soldiers undergo more serious psychological treatment. One of the best strategies for dealing with stress is learning how to relax. However, relaxing is difficult to achieve in a battlefield. In this chapter we suggest the use of mobile multimedia technology--PDA/cellular phones--for the provision of advanced coping techniques suitable to the battlefield context. Specifically, we developed a protocol based on mobile narratives, to be experienced on mobile multimedia technology--3G cellular phones or PDAs--like the one now under development by the US Army within the "Soldier as a System--SaaS" and "Future Combat Systems--FCS" projects. Mobile narratives are audio-visual experiences, implemented on mobile devices, in which the narrative component is a critical aspect to induce a feeling of presence and engagement. Through the link between the feeling of presence and the emotional state, mobile narratives may be used to improve the mood state in their users. The rationale of the approach and a preliminary test of the proposed method are presented and discussed.

    Summary In crisis situations, such as transportation catastrophes, terrorist attacks or contamination with chemical warfare agents, it is crucial to properly organize and sensibly conduct rescue operations. Among chemical warfare agents, the most toxic ones are the derivatives of organophosphorus compounds. An individual auto-injector kit ‘IZAS-05’ contains auto-injectors, which are devices designed for intramuscular administration of drugs in self-aid or buddy-aid on the battlefield. This paper describes in detail the components of the ‘IZAS-05’ kit, as well as its mode of use and possible contraindications. PMID:22207129

    Full Text Available Fire support of the maneuver operation is a continuous process. It begins with the receiving the task by the maneuver commander and continues until the mission is completed. Yet it is a key issue in combat in the way gain success. Therefore, a real-time mannered solution to fire support problem is a vital component of tactical warfare to the sequence that auxiliary forces or logistic support arrives at the theatre. A new method for deciding on combat fire support is proposed using adaptive neuro-fuzzy inference system (ANFIS in this paper. This study addresses the design of an ANFIS as an efficient tool for real-time decision-making in order to produce the best fire support plan in battlefield. Initially, criteria that are determined for the problem are formed by applying ANFIS method. Then, the ANFIS structure is built up by using the data related to selected criteria. The proposed method is illustrated by a sample fire support planning in combat. Results showed us that ANFIS is valid especially for small unit fire support planning and is useful to decrease the decision time in battlefield.

    Full Text Available This study introduces an improved A* algorithm for the real-time path planning of Unmanned Air Vehicles (UAVs in a 3D large-scale battlefield environment to solve the problem that UAVs require high survival rates and low fuel consumption. The algorithm is able to find the optimal path between two waypoints in the target space and comprehensively takes factors such as altitude, detection probability, and path length into account. It considers the maneuverability constraints of the UAV, including the safety altitude, climb rate, and turning radius, to obtain the final flyable path. Finally, the authors test the algorithm in an approximately 2,500,000 square meter area containing radars, no-fly zones, and extreme weather conditions to measure its feasibility, stability, and efficiency.

    Research involving military service members has shown a strong relationship between combat experiences and increased risk for posttraumatic stress disorder (PTSD) and other mental health problems. Comparatively little research has examined the relationship between combat experiences, PTSD, aggression, and unethical conduct on the battlefield, although news stories sometimes suggest links between unethical conduct and disorders such as PTSD. This study systematically examined whether unethical conduct is a proxy for aggression and whether specific combat experiences and PTSD are independently associated with unethical behavior. The results of this study indicate that aggression (β = 0.30) and specific combat experiences (particularly, witnessing war atrocities [β = 0.14] and fighting [β = 0.13]) are much more strongly associated with unethical conduct than is PTSD (β = 0.04).

  7. Military morality transformed: weapons and soldiers on the nineteenth-century battlefield.

    2011-01-01

    The increased lethality of nineteenth-century “arms of precision” caused military formations to disperse in combat, transforming the ordinary soldier from a near automaton, drilled to deliver random fire under close supervision, into a moral agent who exercised a degree of choice about where, when, and how to fire his weapon. The emerging autonomy of the soldier became a central theme in contemporary tactical debates, which struggled to reconcile the desire for discipline with the individual initiative necessary on the battlefield. This tactical conundrum offers revealing insights about human aggression and mass violence. Its dark legacy was the propagation of military values into civilian society, thus paving the way for the political soldiers of the twentieth century.

    2004-01-01

    Danish battlefield surgery in the period between the birth of Christ and the year 500 AD is exemplified by a reinterpretation of artefacts found in the sacrificial bogs at Thorsbjerg, Nydam, Ejsbøl, Illerup Adal, Vimose and Kragehul, reinterpreted in the light of classic European and Egyptian archaeological finds and ethno-archaeological parallels against the background of the author's years of experience as a practicing specialist in gynaecology and obstetrics. No surgical instruments from the Iron Age have previously been construed or identified as such in Denmark or Schleswig-Holstein. The purpose of this paper is to examine the possible finding and identificiation of surgical instruments - or what could be construed as a battlefield surgeons instruments - among artefacts deposited in the above-mentioned sacrificial bogs in the Iron Age. In this paper, the term 'surgical instrument' is defined as an instrument used in teh practice of medicine. Material for the study was collected in a review of illustrations in published works about these bog finds, localising these artefacts and examining them at the museums at which they were located. Also examined was museum storage of artefacts that had been excavated in the above-mentioned bogs. In an effort to reinterpret the function of the artefacts, they were compared with known surgical instruments found in the geographical areas controlled by the Greeks and later the Romans and with pictures of artefacts and a few written sources form the same area. They were also compared with ethnographic parallels. The material upon which the paper is based consists of a total of 67 artefacts, each identified as being from one of the above-mentioned bogs. Of these 67 artefacts, 40 can be indentifed and reinterpreted as being surgical instruments and 27 are toilet sets, i.e. tweezers for personal use or sets consisting of tweezers connected by a metal ring to either an ear pick or a nail cutter. Analysis of the artefacts revealed

    The U.S. military uses large amounts of fuel during deployments and battlefield operations. This project sought to develop a lightweight, small form-factor, soldier-portable advanced thermoelectric (TE) system prototype to recover and convert waste heat from various deployed military equipment (i.e., diesel generators/engines, incinerators, vehicles, and potentially mobile kitchens), with the ultimate purpose of producing power for soldier battery charging, advanced capacitor charging, and other battlefield power applications. The technical approach employed microchannel technology, a unique “power panel” approach to heat exchange/TE system integration, and newly-characterized LAST (lead-antimony-silver-telluride) and LASTT (lead-antimony-silver-tin-telluride) TE materials segmented with bismuth telluride TE materials in designing a segmented-element TE power module and system. This project researched never-before-addressed system integration challenges (thermal expansion, thermal diffusion, electrical interconnection, thermal and electrical interfaces) of designing thin “power panels” consisting of alternating layers of thin, microchannel heat exchangers (hot and cold) sandwiching thin, segmented-element TE power generators. The TE properties, structurally properties, and thermal fatigue behavior of LAST and LASTT materials were developed and characterized such that the first segmented-element TE modules using LAST / LASTT materials were fabricated and tested at hot-side temperatures = 400 °C and cold-side temperatures = 40 °C. LAST / LASTT materials were successfully segmented with bismuth telluride and electrically interconnected with diffusion barrier materials and copper strapping within the module electrical circuit. A TE system design was developed to produce 1.5-1.6 kW of electrical energy using these new TE modules from the exhaust waste heat of 60-kW Tactical Quiet Generators as demonstration vehicles.

    Full Text Available The Battle of the Dardanelles (Çanakkale, also known as the Gallipoli Campaign, played a crucial role in the construction and endorsement of national identity, irrespective of the immediate consequences such as the prolongation of the war or the resignation of Winston Churchill upon failure. The Battle of the Dardanelles is commemorated every year in Turkey, Australia and New Zealand, as a day of remembrance. The battlefields at Dardanelles were reinstated as the Gallipoli Peninsula Historical National Park in 1973. The park covers numerous cemeteries of soldiers from both sides, memorials, museums and the battlefields in an area of 33,000 hectares. The park provides a vivid setting and depiction of the war experience, and stands out as the most important battlefield site in Turkey.The aim of this paper is to analyze battlefield tourism in Çanakkale in terms of its components and its impact on domestic and international tourism in Turkey. Battlefield tourism in Çanakkale encompasses not only the battlefield itself, but also the Çanakkale Victory Day in Turkey, March 18th, and the Anzac Day in Australia, April 25th. While domestic tourism contributes to the revival of collective memory and to the building of national identity, international tourism provides representations of national heritage as a source of political legitimacy. Unique to this case, battlefield tourism plays a significant role in the construction of a long-distance tourism network between Australia, and Turkey. The annual flow of descendants of ANZAC (Australian and New Zealand Army Corps soldiers is an important source of tourism activity in the area.

    1986-06-01

    Performance characteristics of the US Army DT-236 battlefield personnel dosimetry system were evaluated using the Health Physics Research Reactor at Oak Ridge National Laboratory. The DT-236 dosimeter is designed to measure total (neutron plus gamma) radiation dose using a radiophotoluminescent (RPL) detector for gamma rays and a silicon diode for fast neutrons. Areas considered in this evaluation included preirradiation dose indication; accuracy and precision of total, gamma, and neutron dose measurements; fading; angular response; temperature dependence; and relative dosimeter response in air and on various body locations. Experimental results for a variety of radiation fields and dose levels indicate that the existing system overestimates total, neutron, and gamma radiation doses in air by about 20 to 60% relative to reference values. Associated measurement precisions were about +-5% of the means for doses above approximately 0.5 Gy. Fading characteristics, angular dependence, and temperature dependence of the RPL and diode systems were consistent with results expected based on detector characteristics and previous performance studies. Recommendations to improve existing reader performance and measurement accuracy are also presented.

    2012-12-01

    Full Text Available Military Applications of Wireless Sensor Network in domains of maximizing security and gaining maximum benefits while attacking the opponent is a challenging and prominent area of research now-a-days. A commander’s goal in a battle field is not limited by securing his troops and the country but also to deliver proper commands to assault the enemies using the minimum number of resources. In this paper, we propose two efficient and low cost approximation algorithms—the maximum clique analysis and the maximum degree analysis techniques. Both of the techniques find the strategies of maximizing the destruction in a battlefield to defeat the opponent by utilizing limited resources. Experimental results show the effectiveness of the proposed algorithms in the prescribed areas of applications. Gaining the cost-effectiveness of the algorithms are also major concerns of this research. A comparative study explaining the number of resources required for commencing required level of destruction made to the opponents has been provided in this paper. The studies show that the maximum degree analysis technique is able to perform more destruction than the maximum clique analysis technique using same number of resources and requires relatively less computational complexity as well.

    Isolated patches of native vegetation in human-modified landscapes are important reservoirs of biological diversity because they may be the only places in which rare or native species can persist. Manassas National Battlefield Park, Virginia, is an island embedded in a matrix of intensively modified lands; it is becoming increasingly isolated due to growth of the greater Washington, D.C. area. A series of cliffs along Bull Run support an eastern white pine community disjunct from its more typical range in the Appalachian Mountains. Cliffs frequently support vegetation communities that differ from surrounding habitat. In this ecological context, the cliffs along Bull Run are islands of specialized habitat within an island of natural and semi-natural communities (the park), surrounded by a human-dominated landscape. A floral survey of these cliffs was a top priority identified by the National Park Service National Capital Region via the National Resource Preservation Program; in 2014, we completed a floral survey of 11 cliffs in the park. We recorded 282 species in 194 genera and 83 families, including 23 newly documented species for the park.

  18. Modeling the Mycobacterium tuberculosis granuloma – The critical battlefield in host immunity and disease

    Evelyn eGuirado

    2013-04-01

    Full Text Available Granulomas are the hallmark of Mycobacterium tuberculosis (M.tb infection and thus sit at the center of tuberculosis (TB immunopathogenesis. TB can result from either early progression of a primary granuloma during the infection process or reactivation of an established granuloma in a latently infected person. Granulomas are compact, organized aggregates of immune cells consisting of blood-derived infected and uninfected macrophages, foamy macrophages, epithelioid cells (uniquely differentiated macrophages and multinucleated giant cells (Langerhans cells surrounded by a ring of lymphocytes. The granuloma’s main function is to localize and contain M.tb while concentrating the immune response to a limited area. However, complete eradication does not occur since M.tb has its own strategies to persist within the granuloma and to reactivate and escape under certain conditions. Thus M.tb-containing granulomas represent a unique battlefield for dictating both the host immune and bacterial response. The architecture, composition, function and maintenance of granulomas are key aspects to study since they are expected to have a profound influence on M.tb physiology in this niche. Granulomas are not only present in mycobacterial infections; they can be found in many other infectious and non-infectious diseases and play a crucial role in immunity and disease. Here we review the models currently available to study the granulomatous response to M.tb.

    The stop-signal paradigm has been widely adopted as a way to parametrically quantify the response inhibition process. To evaluate inhibitory function in realistic environmental settings, the current study compared stop-signal responses in two different scenarios: one uses simple visual symbols as go and stop signals, and the other translates the typical design into a battlefield scenario (BFS) where a sniper-scope view was the background, a terrorist image was the go signal, a hostage image was the stop signal, and the task instructions were to shoot at terrorists only when hostages were not present but to refrain from shooting if hostages appeared. The BFS created a threatening environment and allowed the evaluation of how participants’ inhibitory control manifest in this realistic stop-signal task. In order to investigate the participants’ brain activities with both high spatial and temporal resolution, simultaneous functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) recordings were acquired. The results demonstrated that both scenarios induced increased activity in the right inferior frontal gyrus (rIFG) and presupplementary motor area (preSMA), which have been linked to response inhibition. Notably, in right temporoparietal junction (rTPJ) we found both higher blood-oxygen-level dependent (BOLD) activation and synchronization of theta-alpha activities (4–12 Hz) in the BFS than in the traditional scenario after the stop signal. The higher activation of rTPJ in the BFS may be related to morality judgments or attentional reorienting. These results provided new insights into the complex brain networks involved in inhibitory control within naturalistic environments. PMID:27199708

    Since 1992, military medicine has considered the relevance, sustainability, and promise of telemedicine in the context of its mission and obligations for service members at home and in war zones. The US Army telemedicine program covers 22 time zones and generates over 5000 tele-consults per month for over 20 medical specialties. More recently the advances in mobile computing and increased adoption of the Smartphone with evolving capabilities for imaging and body-worn sensor integration has emerged in the field called mobile health, or mHealth. This presentation highlights the first 10 years of the U.S. Army mHealth program and includes how similar technologies have translated to wide-scale civilian health care implementation, including a relevant project for Veterans at the University of Pittsburgh. Examples include the successful US Army "mCare" program developed to augment soldier rehabilitation management with USbased geographically dispersed providers that utilizes secure mobile messaging and the soldier's own cell phone. Additional research interests will describe the use of smartphones on the battlefield enabling capture of operational medical data to improve casualty evacuation and outcome. A DoD-funded traumatic brain injury research project developed for Veterans at the University of Pittsburgh includes a mobile health application that demonstrates the effectiveness of communicating with patients through their personal mobile devices with care managers. Preliminary data for all the projects presented are encouraging for adoption and utilization of a mobile telemedicine platform to meet the complex needs of casualties injured or recovering from a broad range of injuries in unique geographic settings.

    Full Text Available Background: An assessment of hemodynamic stability is central to surgical decision-making in the management of battlefield ballistic torso trauma (BBTT. Aims: To analyse the utility of admission physiological parameters in characterising hemodynamic stability. Settings and Design: A retrospective analysis of consecutive admissions, with BBTT, to forward surgical facility in Afghanistan. Materials and Methods: The cohorts′ admission physiology, need for operative intervention, and mortality data were collected retrospectively. The cohort was divided into patients requiring surgery for Life-Threatening Torso Hemorrhage (LTTH and those not requiring immediate surgery (non-LTTH. Statistical Analysis: Parameters were compared using two sample t tests, Mann-Whitney, Fisher′s exact, and Chi-square tests. Receiver operator characteristic curves were used to identify significant parameters and determine optimum cut-off values. Results: A total of 103 patients with isolated BBTT were identified: 44 in the LTTH group and 59 in the non-LTTH group. The mean New Injury Severity Score ± Standard Deviation (NISS±SD was 28±14 and 13±12, respectively. The heart rate, systolic blood pressure (SBP, pulse pressure, shock index (SI=heart rate/SBP and base excess were analysed. SI correlated best with the need for surgical torso hemorrhage control, P<0.05. An optimal cut-off of 0.9 was identified, producing a positive and negative predictive value of 81% and 82%, respectively. Conclusions: Shock index (SI is a useful parameter for helping military surgeons triage BBTT, identifying patients requiring operative torso hemorrhage control. SI performance requires a normal physiological response to hypovolemia, and thus should always be considered in clinical context.

    In addition to life-saving interventions, the assessment of pain and subsequent administration of analgesia are primary benchmarks for quality emergency medical services care which should be documented and analyzed. Analyze US combat casualty data from the Department of Defense Trauma Registry (DoDTR) with a primary focus on prehospital pain assessment, analgesic administration and documentation. Retrospective cohort study of battlefield prehospital and hospital casualty data were abstracted by DoDTR from available records from 1 September 2007 through 30 June 2011. Data included demographics; injury mechanism; prehospital and initial combat hospital pain assessment documented by standard 0-to-10 numeric rating scale; analgesics administered; and survival outcome. Records were available for 8,913 casualties (median ISS of 5 [IQR 2 to 10]; 98.7% survived). Prehospital analgesic administration was documented for 1,313 cases (15%). Prehospital pain assessment was recorded for 581 cases (7%; median pain score 6 [IQR 3 to 8]), hospital pain assessment was recorded for 5,007 cases (56%; median pain score5 [CI95% 3 to 8]), and 409 cases (5%) had both prehospital and hospital pain assessments that could be paired. In this paired group, 49.1% (201/409) had alleviation of pain evidenced by a decrease in pain score (median 4,, IQR 2 to 5); 23.5% (96/409) had worsening of pain evidenced by an increase in pain score (median 3, CI95 2.8 to 3.7, IQR 1 to 5); 27.4% (112/409) had no change; and the overall difference was an average decrease in pain score of 1.1 (median 0, IQR 0 to 3, p prehospital and hospital pain assessment documentation and prehospital analgesic documentation. Our study demonstrates that prehospital pain assessment, management, and documentation remain primary targets for performance improvement on the battlefield. Results of paired prehospital to hospital pain scores and time-series analysis demonstrate both feasibility and benefit of prehospital analgesics

    2014-06-01

    A key weapon in the insurgents' armamentarium against coalition and local security forces in Iraq and Afghanistan has been the use of anti-vehicle mines and improvised explosive devices (IEDs). Often directed against vehicle-borne troops, these devices, once detonated, transfer considerable amounts of energy through the vehicle to the occupants. This results in severe lower limb injuries that are frequently limb threatening. Fundamental to designing novel mitigation strategies is a requirement to understand the injury mechanism by developing appropriate injury modelling tools that are underpinned by the analysis of contemporary battlefield casualty data. This article aims to summarise our understanding of the clinical course of lower limb blast injuries from IEDs and its value in developing unique injury modelling test-beds to evaluate and produce the next generation of protective equipment for reducing the devastating effects of blast injury.

    While the list presented here is by no means a comprehensive list of all of the research areas of interest in battlefield trauma care, much less a list of research needs across the entire continuum of combat casualty care, it does provide the collective judgment of the CoTCCC about the highest priorities for RDT&E that relate to battlefield trauma care. Two additional observations should be made regarding that point: (1) As the landmark Eastridge et al. 2012 study convincingly documented, most combat fatalities occur in the prehospital phase of care, so research efforts that enable Combat medics, corpsmen, and PJs to care for their casualties more effectively will convey the highest probability of further reducing the case fatality rate and preventable deaths among US Combat casualties; and (2) inasmuch as the mission of the CoTCCC is to update the TCCC Guidelines as needed, this group has excellent visibility of the most important current research questions in battlefield trauma care.

  6. Geophysical Field Work for Educators: Teachers Use Ground-Penetrating Radar to Study San Jacinto Battlefield Park

    Henning, A. T.; Sawyer, D. S.; Milliken, K.

    2008-12-01

    In July 2008, a group of Houston area K-12 teachers investigated San Jacinto Battlefield Park in La Porte, Texas, utilizing ground-penetrating radar (GPR) to image the subsurface and global positioning system (GPS) units to map surface features. Participants were in-service K-12 teachers from urban Houston school districts where the majority of students are members of historically underrepresented minority groups. Over a period of two weeks, participants acquired and interpreted GPR profiles in the park, mapped surface features using hand-held GPS units, and analyzed the data using ArcGIS software. This summer experience was followed by a content-intensive academic year course in Earth Science. The Battle of San Jacinto took place on April 21, 1836, and was the decisive battle in the Texas Revolution. The site is thought to contain numerous in-situ artifacts dropped by the Texan and Mexican armies, as well as unmarked burials from the early 1800's. Two stratigraphic units were identified from the GPR profiles and matched to strata exposed through archaeological excavations. The stratigraphic units are interpreted as recent flood/storm deposits with soil formation on Pleistocene deltaic deposits of a previous sea-level highstand. In addition to the stratigraphy, a number of isolated subsurface anomalies (possibly artifacts) were identified. Participants also interpreted past shoreline positions using vintage aerial photographs and acquired several transects of GPS positions along the shoreline. Participants confirmed that the area is in fact subsiding, rather than being eroded. Participants not only experienced the scientific process but also utilized geophysics for community service (i.e. contributing educational material to the park). Through background research, they derived a rich historical context for their investigation and learned to appreciate the multi-disciplinary aspect of solving real- world scientific problems.

  7. Forward Surgical Teams provide comparable outcomes to combat support hospitals during support and stabilization operations on the battlefield.

    Forward Surgical Teams (FST) provide forward deployed surgical care within the battle space. The next level of care in theater, the Combat Support Hospitals (CSH), are distinguished from the FST by advanced resource capabilities including more complex diagnostic imaging, laboratory support with blood banking, and intensive care units. This study was intended to assess the effect of FST capability on the outcome of seriously injured casualties in comparison to the CSH. We reviewed all casualty records in the Joint Theater Trauma Registry database from April 2004 to April 2006. The study cohort included all US military battle casualties who were admitted to either a FST or a CSH and were not returned to duty within 72 hours. Data were tabulated and assessed for basic demographics, mechanism of injury, injury severity score, ventilator and critical care days, and mortality. Statistical inferences were made using Chi square and Student's t tests. As of April 2006, the above information was available in the Joint Theater Trauma Registry on 2,617 US military battle casualties who survived to reach care at a FST and/or CSH. Of this population, 77 subsequently died of wounds and 2,540 survived. We found no significant difference in died of wounds rates between the sample populations or rates of ventilator or critical care days between the two groups, nor did controlling for injury severity score alter this picture. The most significant predictor of mortality in both these groups was head injury. The disparity between the availability of the highest level of injury care and the ability to care for injury as soon as possible is an issue of central importance to both the civilian and military trauma care communities. Our analysis demonstrates that despite the operational and logistic challenges that burden the FST, this level of surgical care confers equivalent battlefield injury outcome results compared with the CSH.

    Free Space Optics (FSO) technology was originally envisioned to be a viable solution for the provision of high bandwidth optical connectivity in the last mile of today's telecommunications infrastructure. Due to atmospheric limitations inherent to FSO technology, FSO is now widely envisioned as a solution for the provision of high bandwidth, temporary mobile communications links. The need for FSO communications links will increase as mobility is introduced to this technology. In this paper, a theoretical solution for adding mobility to FSO communication links is introduced. Three-dimensional power estimation studies are presented to represent mobile FSO transmission under various weather conditions. Three wavelengths, 0.85, 1.55 and 10 um, are tested and compared to illustrate the pros and cons of each source wavelength used for transmission, depending on prevalent weather conditions and atmospheric turbulence conditions. A simulation analysis of the transmission properties of the source wavelengths used in the study is shown.

  9. THE INFLUENCE OF GEOLOGY ON BATTLEFIELD TERRAIN AND IT’S AFFECTS ON MILITARY OPERATIONS IN MOUNTAINS AND KARST REGIONS: EXAMPLES FROM WW1 AND AFGHANISTAN

    Full Text Available During the World War I conflict between the Austrian and Italian army, Austrian engineer units constructed hallways in the karst region of Soča river. Those hallways, karst phenomena (caverns, caves and other fortifications, gave the Austrian army a tactical advantage. The construction principle of caverns is the consequence of the geological structure of the terrain. We are watching another military conflict in Afghanistan. In country where many armies in history have been defeated, where the terrain morphology condition a guerilla tactic, where the function effect of modern military technology is limited by battlefield configuration and with low military value of individual target, we are creating a "picture" of the possible view of the future battlefield. Al-Qai'da operatives in east Afghanistan take advantage of the opportunity of geological structure of the terrain and construct tunnel network across natural caves. Although the tunnel network in Afghanistan is constructed mostly in sandstones and metamorphic rocks, we may partly compare it with Austrian hallways. In that sense this work shows the influence of geological structure of the terrain on the effect of military operations in mountains and karst regions, and the analogy between military operations on the Soča river and military operations in Afghanistan.

    U.S. World War II novels usually have two themes--anti-fascist and indictment of the modem power, and two battlefields--the fight against the enemy in the front line and the class struggle between the officers and soldiers in the rear line of battlefield. According to the charac- teristics of sexual politics, this paper studies the phenomenon of sex in these novels, and finds out that sex as the hidden battlefield and one kind of the writing strategies works for ideologies of the two lines and also implies the third front line threatening the soldiers' lives. This paper analyzes how in the World War II novels the authors condemn the war and the modem power through a va- riety of sexual behavior, involving heterosexual sex, homosexual sex and sexual violence. However, when sex becomes a tool of political expression, it loses its original meaning and bears too much expectation from authors and readers.%美国二战小说具有两个主题——反法西斯以及控诉现代社会权力,两个战场一~敌我斗争的前线战场和官兵之间阶级斗争的后方战场。根据性的政治属性,本文研究美国二战小说中的性行为,发现性作为隐形战场和写作策略为前两个战场的意识形态服务,并隐含威胁士兵生命的第三条战线。文章揭示了二战小说作者如何通过各种性行为,包括异性、同性和性暴力,谴责战争和抗议权力。当性行为变成政治表述工具时,它失去本身的含义而承载作者和读者过多的期望。

    2006-05-01

    CHORALE (simulated Optronic Acoustic Radar battlefield) is used by the French DGA/DET (Directorate for Evaluation of the French Ministry of Defense) to perform multi-sensors simulations. CHORALE enables the user to create virtual and realistic multi spectral 3D scenes, and generate the physical signal received by a sensor, typically an IR sensor. To evaluate their efficiency in visible and infrared wavelength, simulation tools, that give a good representation of physical phenomena, are used. This article describes the elements used to prepare data (3D database, materials, scenario, ...) for the simulation, and the set of tools (SE-FAST-IR), used in CHORALE for the Real Time simulation in the infrared spectrum. SE-FAST-IR package allows the compilation and visualization of 3D databases for infrared simulations. It enables one to visualize complex and large databases for a wide set of real and pseudo-real time applications. SE-FAST-IR is based on the physical model of the Non Real Time tool of CHORALE workshop. It automatically computes radiance textures, Open GL light source and fog-law parameters for predefined thermal and atmospheric conditions, specified by the user.

    2014-11-01

    When Britain went to war in 1914, the British Expeditionary Force was deployed without a single dentist. Initially considered combatants, the only dental professionals who could serve at the Front were medically qualified dental surgeons in the Royal Army Medical Corps. In treating the traumatic facial and jaw injuries caused by trench warfare, the dental surgeons of this era earned their place on specialist surgical teams and established the principles of oral and maxillofacial surgery. This article will examine the contribution of specialist dental surgeons to the management of facial and jaw wounds in the First World War along the chain of evacuation from the battlefield to the home front, using illustrative examples from the Hunterian Museum at the Royal College of Surgeons of England.

    2006-01-01

    Virtual battlefield has excessive objects and broad range. The traditional operation uses a dynamic object to traverse every object, so it will greatly influence the real time of collision detection. In this paper, a real-time collision detection algorithm of area of interested (AOI) is proposed based on oriented bounding box (OBB) method in virtual battlefield environment. By this algorithm collision detection only happens in AOI but not in entire environment when inner states change. The algorithm can greatly improve availability of collision detection without reducing its accuracy of collision detection. Meanwhile it can decrease computation load.%虚拟战场环境地域广阔、战场目标众多,传统的碰撞检测方法是遍历战场中的每一个目标,这将大大影响碰撞检测的实时性.提出了基于OBB战场环境的感兴趣区域(AOI)的实时碰撞检测算法.当战场环境内部状态发生变化时,该算法仅对AOI区域而不是整个战场环境进行碰撞目标的检测,可大大提高虚拟战场环境中碰撞检测的有效性,而且完全不降低碰撞检测的精确性,减少了系统碰撞检测的负担,提高了系统的实时性.

  18. On analog simulation of ionization cooling of muons

    Energy Technology Data Exchange (ETDEWEB)

    Xie, Ming

    2001-06-18

    Analog simulation, proposed here as an alternative approach for the study of ionization cooling of muons, is a scaled cooling experiment, using protons instead of muons as simulation particles. It is intended to be an effective and flexible, quick and inexpensive experiment for the understanding and validation of unprecedentedly complicated cooling physics, for the demonstration and optimization of various elaborated techniques for beam manipulation in 6D phase space. It can be done and perhaps should be done before the costly and time-consuming development of extremely challenging, muon-specific cooling technology. In a nutshell, the idea here is to build a toy machine in a playground of ideas, before staking the Imperial Guard of Napoleon into the bloody battlefield of Waterloo.

    2007-04-01

    As the Army's Future Combat Systems (FCS) introduce emerging technologies and new force structures to the battlefield, soldiers will increasingly face new challenges in workload management. The next generation warfighter will be responsible for effectively managing robotic assets in addition to performing other missions. Studies of future battlefield operational scenarios involving the use of automation, including the specification of existing and proposed technologies, will provide significant insight into potential problem areas regarding soldier workload. The US Army Tank Automotive Research, Development, and Engineering Center (TARDEC) is currently executing an Army technology objective program to analyze and evaluate the effect of automated technologies and their associated control devices with respect to soldier workload. The Human-Robotic Interface (HRI) Intelligent Systems Behavior Simulator (ISBS) is a human performance measurement simulation system that allows modelers to develop constructive simulations of military scenarios with various deployments of interface technologies in order to evaluate operator effectiveness. One such interface is TARDEC's Scalable Soldier-Machine Interface (SMI). The scalable SMI provides a configurable machine interface application that is capable of adapting to several hardware platforms by recognizing the physical space limitations of the display device. This paper describes the integration of the ISBS and Scalable SMI applications, which will ultimately benefit both systems. The ISBS will be able to use the Scalable SMI to visualize the behaviors of virtual soldiers performing HRI tasks, such as route planning, and the scalable SMI will benefit from stimuli provided by the ISBS simulation environment. The paper describes the background of each system and details of the system integration approach.

    Directory of Open Access Journals (Sweden)

    M. R. Subramanian

    1987-10-01

    Full Text Available The battlefield simulation is often faced with a bewildering array of conflicting stresses and challenges. Communication is currently slower and more costly than computation. Expert System technologies such as production rule systems allow one to acquire and represent the collection of heuristic rules in computer compatible form. The system also include master control programs that determine the order in which these rules should be applied against the monitored system performance to arrive at appropriate system control. These expert systems are used in two nodes, both as an intelligence assistant to the expert, amplifying the capacity and quality of his work, and as a surrogate for an expert when he is not available. An Expert support System (ESS designed and developed for combat simulation has been enumerated in this article. The quality and the reliability of the inferred tactical situation is improved by using PROLOG. This formal AI language is used for validating and checking sensor detections for consistency and logical plausibility. The supremacy of PROLOG for creating and interrogating a data base helps maintaining a reasonably coherent feature of the tactical situation. The perils and pitfalls of tackling with expert systems have also been underscored.

  17. Development of a 5-DOF force feedback laparoscopic interface for simulation and telesurgery

    Science.gov (United States)

    Ben-Ur, Ela; Salisbury, J. Kenneth, Jr.

    2000-08-01

    Laparoscopic surgery reduces recovery time and risk of complications over conventional methods for abdominal procedures, making it particularly suited to battlefield medicine. However, laparoscopy challenges the surgeon to work under many limitations: motion is reflected about the trocar; access inside the body is restricted; visual feedback is generally only 2D; and haptic, or touch, information is reduced. As such, the importance of training for developing sensitivity to the existing haptic cues becomes apparent, and the problem arises of how to distribute the services of relatively few highly trained surgeons to widespread battlefield locations. A force- feedback haptic interface can play a critical role in both of these functions, providing realistic or enhanced sensations to a laparoscopy simulator or a telesurgery system. The work described here was directed at continuing the work of earlier force-feedback systems, which provide up to the first three degrees of freedom (DOF) in laparoscopy (pitch, yaw, and insertion relative to the trocar), toward creating a complete and high-fidelity haptic interface. Careful requirements analysis using data from surgeon interviews, operating room observations, and task analyses, was the basis for specifying the technical attributes and configuration of the new system. The resulting interface offers the surgeon real laparoscopic tools with force feedback to all five degrees of freedom in laparoscopy, using a lifelike torso in which trocar location is easily changed. A light and compact 2-DOF device was developed to supplement one of the available 3-DOF devices, providing the additional forces in tool rotation and gripper feedback. Next year, the system will be integrated into a software stimulation currently in development at the Center for Minimally Invasive Therapy (CIMIT).

    2013-01-01

    This paper discusses the techniques used to simulate the proposed upgrade to the ASPIC line at ISOLDE, VITO. It discusses the process used in the program SIMION by explaining how to start with an Autodesk Inventor drawing and import this into SIMION to get a working simulation. It then goes on to discuss the pieces of VITO which have been simulated in the program and how they were simulated. Finally, it explains a little about the simulations of the full beamline which have been done and discusses what still needs to be done.

    This chapter outlines the conventions and pleasures of simulation games as a category, and explores the complicated and contested term simulation. This concept goes to the heart of what computer games and video games are, and the ways in which they articulate ideas, processes, and phenomena between their virtual worlds and the actual world. It has been argued that simulations generate and communicate knowledge and events quite differently from the long-­dominant cultural mode of narrative. Th...

    In the last two decades, simulation tools made a significant contribution to the great progress in development of power electronics. Time to market was shortened and development costs were reduced drastically. Falling costs, as well as improved speed and precision, opened new fields of application. Today, continuous and switched circuits can be mixed. A comfortable number of powerful simulation tools is available. The users have to choose the best suitable for their application. Here a simple rule applies: The best available simulation tool is the tool the user is already used to (provided, it can solve the task). Abilities, speed, user friendliness and other features are continuously being improved—even though they are already powerful and comfortable. This paper aims at giving the reader an insight into the simulation of power electronics. Starting with a short description of the fundamentals of a simulation tool as well as properties of tools, several tools are presented. Starting with simplified models ...

    MOOG, Inc. supplies hydraulic actuators for the Space Shuttle. When MOOG learned NASA was interested in electric actuators for possible future use, the company designed them with assistance from Marshall Space Flight Center. They also decided to pursue the system's commercial potential. This led to partnership with InterActive Simulation, Inc. for production of cabin flight simulators for museums, expositions, etc. The resulting products, the Magic Motion Simulator 30 Series, are the first electric powered simulators. Movements are computer-guided, including free fall to heighten the sense of moving through space. A projection system provides visual effects, and the 11 speakers of a digital laser based sound system add to the realism. The electric actuators are easier to install, have lower operating costs, noise, heat and staff requirements. The U.S. Space & Rocket Center and several other organizations have purchased the simulators.

Because of many different types of applications, the simulators must be adjustable to replicate many different areas of the solar radiation spectrum. Simulators are laboratory tools for such purposes as testing and calibrating solar cells, or other solar energy systems, testing dyes, paints and pigments, pharmaceuticals and cosmetic preparations, plant and animal studies, food and agriculture studies and oceanographic research.

  9. Field tests and computational simulations of the explosion of buried charges

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Modelling buried explosion is a matter of concern for vehicle protection. Indeed, in the battlefield, Improvised Explosive Devices (IEDs are one of the major threats for land vehicles and, more specifically, for their underbelly. Two series of field tests using several masses of explosives have been performed, varying certain geometrical parameters, the nature and the physical properties of the soil. These controlled tests have shown that the impulse transmitted to the vehicle is a function of the saturation of the soil as well as of depth of burial of the explosive. In an effort to simulate the phenomena that take place during the explosions, these tests have been used to feed the data requested in computational simulations in a finite element context. Soil modelling presents its own difficulties, especially because soil is a porous medium and the three phases (solid grains, water and air must be considered. A non linear viscoplastic cap model has been developed where the degree of saturation is variable. The yield surface includes a failure part, a cap and a tension cutoff. Soil stiffening associated with the air expulsion has been observed to be an important aspect of the model.

    地形场景是整个虚拟战场推演系统的重要组成元素.由于现代战争中融合陆海空各军种庞大的武器元素和环境元素,地形渲染可获取的资源十分有限,而涉及的数据量却非常巨大,是影响整个系统性能的瓶颈.针对该问题,设计静态和动态结合的嵌套四叉树结构组织大地形数据,以实现大数据的动态平衡调度;提出基于环形索引模式的高程拟合算法来避免不同分辨率模块间的裂缝.实验表明,该方法不仅有效提高了推演系统的实时性和沉浸感,还极大地降低了系统的资源负载率.%Terrain scene is an important element in entire virtual battlefield deductive system.Since modern battle contains huge amount of weapon elements of different military services including army,navy and air force and environment elements,whereas the acquirable resource for terrain rendering is very limited,and the data amount involved is bulky,it becomes the bottleneck of the whole system.To solve this problem,we design a nested quadtree structure with static and dynamic combination to organise the large terrain data so as to realise the dynamic balance scheduling; we also propose the elevation fitting algorithm which is based on annulus index mode to avoid the cracks between different resolutions modules.Experiments show that this method improves the real-time property and immersion of the deductive system,and also greatly reduces the resource loading rate of the system.

    The DSN Simulator (wherein DSN signifies NASA's Deep Space Network) is an updated version of the software described in DSN Array Simulator (NPO-44506), Software Tech Briefs (Special supplement to NASA Tech Briefs), Vol. 32, No. 9 (September 2008), page 26. To recapitulate: This software is used for computational modeling of proposed DSN facilities comprising arrays of antennas and transmitting and receiving equipment for microwave communication with spacecraft on interplanetary missions. Such modeling is performed to estimate facility performance, evaluate requirements that govern facility design, and evaluate proposed improvements in hardware and/or software. The software includes a Monte Carlo simulation component that enables rapid generation of key mission-set metrics (e.g., numbers of links, data rates, and data volumes), and statistical distributions thereof as functions of time. The prior version of the software could model only one DSN facility at a time and included hard-coded, unconfigurable metrics. The present updated version is capable of modeling the entire DSN and provides for configurable metrics, making it possible to perform loading analyses for alternative future DSN architectures and mission-set scenarios. The present version also features an improved user interface and interfaces for exchange of data with other DSN software and with a DSN mission model database.

    2012-09-01

    Full Text Available Wireless Sensor Networks (WSNs have emerged as a new research technology in the distributed computing environment and plays a very important role in the pervasive computing to support various applications. It has a great potential to be utilized in battlefields and in different commercial applications like traffic surveillance, habitat monitoring, construction structures, smart homes, offices and many more. Research on several aspects of WSNs like energy efficiency, power management, rouunrting, topology control, data management and security are progressing extensively. In this technical paper a survey on recent trends in wireless sensor network research, different topologies, routing protocols, simulators and applications is carried out. A smart WSN consists of sensor nodes made of small electronic device and are deployed across a geographical area. These nodes carry out the sensing, processing and transmission of data from different physical environments. They depend on batteries which get drained very soon due to the computation and data transmission to other nodes. The architectures of WSN are mainly depending on application requirements. WSN is a multidisciplinary area of research where different applications developers, users, hardware and software designers need to work closely to implement an efficient application. The different characteristics of the sensor network like flexibility, fault tolerance, high sensing fidelity, low cost and rapid deployment create many new and exciting application areas.

  20. Neuromechanical simulation

    Directory of Open Access Journals (Sweden)

    Donald H Edwards

    2010-07-01

    Full Text Available The importance of the interaction between the body and the brain for the control of behavior has been recognized in recent years with the advent of neuromechanics, a field in which the coupling between neural and biomechanical processes is an explicit focus. A major tool used in neuromechanics is simulation, which connects computational models of neural circuits to models of an animal’s body situated in a virtual physical world. This connection closes the feedback loop that links the brain, the body, and the world through sensory stimuli, muscle contractions and body movement. Neuromechanical simulations enable investigators to explore the dynamical relationships between the brain, the body, and the world in ways that are difficult or impossible through experiment alone. Studies in a variety of animals have permitted the analysis of extremely complex and dynamic neuromechanical systems, they have demonstrated that the nervous system functions synergistically with the mechanical properties of the body, they have examined hypotheses that are difficult to test experimentally, and they have explored the role of sensory feedback in controlling complex mechanical systems with many degrees of freedom. Each of these studies confronts a common set of questions: (i how to abstract key features of the body, the world and the CNS in a useful model, (ii how to ground model parameters in experimental reality, (iii how to optimize the model and identify points of sensitivity and insensitivity, and (iv how to share neuromechanical models for examination, testing, and extension by others.

  19. The liberal battlefields of global business regulation

    Directory of Open Access Journals (Sweden)

    Kate Macdonald

    2010-11-01

    Full Text Available The global justice movement has often been associated with opposition to the broad programme of ‘neoliberalism’ and associated patterns of ‘corporate globalisation’, creating a widespread impression that this movement is opposed to liberalism more broadly conceived. Our goal in this article is to challenge this widespread view. By engaging in critical interpretive analysis of the contemporary ‘corporate accountability’ movement, we argue that the corporate accountability agenda is not opposed to the core values of a liberal project. Rather, it is seeking to reconfigure the design of liberal institutions of individual rights-protection, adjusting these for new material conditions associated with economic globalisation, under which powerful corporations alongside states now pose direct and significant threats to individual rights. This activist agenda is, therefore, much less radical in its challenge to the prevailing liberal global order than it may initially appear, since it functions to buttress rather than corrode many core normative commitments underpinning the liberal political project.

    2005-05-01

    This paper describes development and application of a high-fidelity, seismic/acoustic simulation capability for battlefield sensors. The purpose is to provide simulated sensor data so realistic that they cannot be distinguished by experts from actual field data. This emerging capability provides rapid, low-cost trade studies of unattended ground sensor network configurations, data processing and fusion strategies, and signatures emitted by prototype vehicles. There are three essential components to the modeling: (1) detailed mechanical signature models for vehicles and walkers, (2) high-resolution characterization of the subsurface and atmospheric environments, and (3) state-of-the-art seismic/acoustic models for propagating moving-vehicle signatures through realistic, complex environments. With regard to the first of these components, dynamic models of wheeled and tracked vehicles have been developed to generate ground force inputs to seismic propagation models. Vehicle models range from simple, 2D representations to highly detailed, 3D representations of entire linked-track suspension systems. Similarly detailed models of acoustic emissions from vehicle engines are under development. The propagation calculations for both the seismics and acoustics are based on finite-difference, time-domain (FDTD) methodologies capable of handling complex environmental features such as heterogeneous geologies, urban structures, surface vegetation, and dynamic atmospheric turbulence. Any number of dynamic sources and virtual sensors may be incorporated into the FDTD model. The computational demands of 3D FDTD simulation over tactical distances require massively parallel computers. Several example calculations of seismic/acoustic wave propagation through complex atmospheric and terrain environments are shown.

    Junctional hemorrhage is a common cause of death on the battlefield, but there is no documented direct comparison for the use of junctional tourniquet models by US medics. The purpose of this testing is to assess military medic experience with the use of junctional tourniquets in simulated out-of-hospital trauma care. Nine medics (seven men and two women) used four different junctional tourniquets: Combat Ready Clamp™ (CRoC™; http://www.combatmedicalsystems .com), Abdominal Aortic and Junctional Tourniquet™ (AAJT™; http://www.compressionworks.net), Junctional Emergency Treatment Tool (JETT™; http://www.narescue .com), and SAM Junctional Tourniquet® (SJT®; http://www.sammedical.com/products). These medics also acted as simulated casualties. Effectiveness percentages, as measured by stopped distal pulse by Doppler auscultation, and time to effectiveness were recorded in two tests per tourniquet (72 total tests). Tourniquet users ranked their preference of model by answering the question: "If you had to go to war today and you could only choose one, which tourniquet would you choose to bring?" All tourniquets used were safe under the conditions of this study. Both the SJT and the CRoC had high effectiveness percentages; their rate difference was not statistically significant. The SJT and the CRoC had fast times to effectiveness; their time difference was not statistically significant.

    Recognition and classification of military vehicle is an important research content of information acquirement in battlefield. In order to collect data and study military vehicle classification algorithm, real external field experiment mode is popularly used, however it needs long time and expensive costs. In this paper, the tank model, armored vehicle model and truck model are built in the virtual battlefield simulation platform. The noise signals, magnetic field signals and vibration signals of the military vehicles in simulation environment are collected and used as the sample data for the research of military vehicle classification algorithm. In the same time this paper designs a classification algorithm of military vehicle based on the one-to-one multi-class SVM, and gives out an adjustment strategy for classifier parameters based on the cross-validation method. The experiment results show that, compared to AdaBoost algorithm, the present algorithm has higher classification accuracy on military vehicles.%战车类型的识别分类是现代情报获取的重要研究内容。为了获得数据并研究战车分类算法,常进行外场真实实验,但其时间长、耗资巨大。本文在虚拟战场仿真平台上建立坦克、装甲车、运兵车三种战车模型。利用仿真环境中的战车噪声、磁场、振动特征信号作为样本数据,进行战车的分类算法研究。同时基于一对一多分类支持向量机,设计了一种战车分类算法,并给出了分类器交叉验证参数调整策略。实验表明,相比于AdaBoost算法,文章提出的战车分类算法的分类准确率较高。

    Full Text Available A novel multi-source energy harvester based on solar and radioisotope energy sources is designed and simulated in this work. We established the calculation formulas for the short-circuit current and open-circuit voltage, and then studied and analyzed the optimization thickness of the semiconductor, doping concentration, and junction depth with simulation of the transport process of β particles in a semiconductor material using the Monte Carlo simulation program MCNP (version 5, Radiation Safety Information Computational Center, Oak Ridge, TN, USA. In order to improve the efficiency of converting solar light energy into electric power, we adopted PC1D (version 5.9, University of New South Wales, Sydney, Australia to optimize the parameters, and selected the best parameters for converting both the radioisotope energy and solar energy into electricity. The results concluded that the best parameters for the multi-source energy harvester are as follows: Na is 1 × 1019 cm−3, Nd is 3.8 × 1016 cm−3, a PN junction depth of 0.5 μm (using the 147Pm radioisotope source, and so on. Under these parameters, the proposed harvester can achieve a conversion efficiency of 5.05% for the 147Pm radioisotope source (with the activity of 9.25 × 108 Bq and 20.8% for solar light radiation (AM1.5. Such a design and parameters are valuable for some unique micro-power fields, such as applications in space, isolated terrestrial applications, and smart dust in battlefields.

    COCOA (Cluster simulatiOn Comparison with ObservAtions) creates idealized mock photometric observations using results from numerical simulations of star cluster evolution. COCOA is able to present the output of realistic numerical simulations of star clusters carried out using Monte Carlo or N-body codes in a way that is useful for direct comparison with photometric observations. The code can simulate optical observations from simulation snapshots in which positions and magnitudes of objects are known. The parameters for simulating the observations can be adjusted to mimic telescopes of various sizes. COCOA also has a photometry pipeline that can use standalone versions of DAOPHOT (ascl:1104.011) and ALLSTAR to produce photometric catalogs for all observed stars.

    The simulation software for the ATLAS Experiment at the Large Hadron Collider is being used for large-scale production of events on the LHC Computing Grid. This simulation requires many components, from the generators that simulate particle collisions, through packages simulating the response of the various detectors and triggers. All of these components come together under the ATLAS simulation infrastructure. In this paper, that infrastructure is discussed, including that supporting the detector description, interfacing the event generation, and combining the GEANT4 simulation of the response of the individual detectors. Also described are the tools allowing the software validation, performance testing, and the validation of the simulated output against known physics processes.

    The simulation software for the ATLAS Experiment at the Large Hadron Collider is being used for large-scale production of events on the LHC Computing Grid. This simulation requires many components, from the generators that simulate particle collisions, through packages simulating the response of the various detectors and triggers. All of these components come together under the ATLAS simulation infrastructure. In this paper, that infrastructure is discussed, including that supporting the detector description, interfacing the event generation, and combining the GEANT4 simulation of the response of the individual detectors. Also described are the tools allowing the software validation, performance testing, and the validation of the simulated output against known physics processes.

    Normally, an explosion threat on free field especially from high explosives is very dangerous due to the ground shocks generated that have high impulsive load. Nowadays, explosion threats do not only occur in the battlefield, but also in industries and urban areas. In industries such as oil and gas, explosion threats may occur on logistic transportation, maintenance, production, and distribution pipeline that are located underground to supply crude oil. Therefore, the appropriate blast resistances are a priority requirement that can be obtained through an assessment on the structural response, material strength and impact pattern of material due to ground shock. A highly impulsive load from ground shocks is a dynamic load due to its loading time which is faster than ground response time. Of late, almost all blast studies consider and analyze the ground shock in the fluid-structure interaction (FSI) because of its influence on the propagation and interaction of ground shock. Furthermore, analysis in the FSI integrates action of ground shock and reaction of ground on calculations of velocity, pressure and force. Therefore, this integration of the FSI has the capability to deliver the ground shock analysis on simulation to be closer to experimental investigation results. In this study, the FSI was implemented on AUTODYN computer code by using Euler-Godunov and the arbitrary Lagrangian-Eulerian (ALE). Euler-Godunov has the capability to deliver a structural computation on a 3D analysis, while ALE delivers an arbitrary calculation that is appropriate for a FSI analysis. In addition, ALE scheme delivers fine approach on little deformation analysis with an arbitrary motion, while the Euler-Godunov scheme delivers fine approach on a large deformation analysis. An integrated scheme based on Euler-Godunov and the arbitrary Lagrangian-Eulerian allows us to analyze the blast propagation waves and structural interaction simultaneously.

    Biamonte, J D; Whitfield, J D; Fitzsimons, J; Aspuru-Guzik, A

    2010-01-01

    In his famous 1981 talk, Feynman proposed that unlike classical computers, which would presumably experience an exponential slowdown when simulating quantum phenomena, a universal quantum simulator would not. An ideal quantum simulator would be error resistant, easily controllable, and built using existing technology. Moving away from gate-model and projective measurement based implementations of quantum computing may offer a less resource-intensive, and consequently a more feasible solution. Here we consider an adiabatic quantum simulator which simulates the ground state properties of sparse Hamiltonians consisting of one- and two-body interaction terms, using sparse Hamiltonians with at most three-body interactions. Properties of such Hamiltonians can be well approximated with Hamiltonians containing only two-local terms. The register holding the simulated ground state is brought adiabatically into interaction with a probe qubit, followed by a single diabatic gate operation on the probe which then undergoes...

    1999-07-01

    Current financial, schedule and risk constraints mandate reuse of software components when building large-scale simulations. While integration of simulation components into larger systems is a well-understood process, it is extremely difficult to do while ensuring that the results are correct. Illgen Simulation Technologies Incorporated and Litton PRC have joined forces to provide tools to integrate simulations with confidence. Illgen Simulation Technologies has developed an extensible and scaleable, n-tier, client- server, distributed software framework for integrating legacy simulations, models, tools, utilities, and databases. By utilizing the Internet, Java, and the Common Object Request Brokering Architecture as the core implementation technologies, the framework provides built-in scalability and extensibility.

  3. Discrete-Event Simulation

    2015-04-01

    Full Text Available Abstract Simulation can be regarded as the emulation of the behavior of a real-world system over an interval of time. The process of simulation relies upon the generation of the history of a system and then analyzing that history to predict the outcome and improve the working of real systems. Simulations can be of various kinds but the topic of interest here is one of the most important kind of simulation which is Discrete-Event Simulation which models the system as a discrete sequence of events in time. So this paper aims at introducing about Discrete-Event Simulation and analyzing how it is beneficial to the real world systems.

    2000-01-18

    Algorithms developed to enable the use of atomistic molecular simulation methods with parallel computers are reviewed. Methods appropriate for bonded as well as non-bonded (and charged) interactions are included. While strategies for obtaining parallel molecular simulations have been developed for the full variety of atomistic simulation methods, molecular dynamics and Monte Carlo have received the most attention. Three main types of parallel molecular dynamics simulations have been developed, the replicated data decomposition, the spatial decomposition, and the force decomposition. For Monte Carlo simulations, parallel algorithms have been developed which can be divided into two categories, those which require a modified Markov chain and those which do not. Parallel algorithms developed for other simulation methods such as Gibbs ensemble Monte Carlo, grand canonical molecular dynamics, and Monte Carlo methods for protein structure determination are also reviewed and issues such as how to measure parallel efficiency, especially in the case of parallel Monte Carlo algorithms with modified Markov chains are discussed.

    Delagi, B. A.; Saraiya, N.; Nishimura, S.; Byrd, G.

    1987-01-01

    Simulation of systems at an architectural level can offer an effective way to study critical design choices if (1) the performance of the simulator is adequate to examine designs executing significant code bodies, not just toy problems or small application fragements, (2) the details of the simulation include the critical details of the design, (3) the view of the design presented by the simulator instrumentation leads to useful insights on the problems with the design, and (4) there is enough flexibility in the simulation system so that the asking of unplanned questions is not suppressed by the weight of the mechanics involved in making changes either in the design or its measurement. A simulation system with these goals is described together with the approach to its implementation. Its application to the study of a particular class of multiprocessor hardware system architectures is illustrated.

    1998-07-01

    For transportation planning applications, it is useful to not only model each individual traveler, but also the decision-making process leading to their travel demand. Simulation-based modeling of this process means iterations between the actual transportation micro-simulation and the modules simulating the process making the plans. This means that for understanding a single day of travel, it may be necessary to simulate that day hundreds of times for the iteration process, leading to a considerable strain on computational resources.

  20. Constructing emotion through simulation.

    Science.gov (United States)

    Wilson-Mendenhall, Christine D

    2017-07-21

    Evidence increasingly suggests that simulations implement patterns of prior experience to construct one's current experience, whether that experience is oriented in the past, in the here and now, or in the future. Simulation is the mechanism by which the brain capitalizes on prior learning to efficiently navigate the situation at hand. This review examines the latest developments in theory and empirical research that address simulation during emotional phenomena. Integration of evidence across multiple literatures suggests that simulation accounts provide a unifying framework across many different emotional phenomena and highlights the importance of investigating dynamics, complexity, and variation in emotional experiences moving forward.

    The angular and energy resolutions of the TANGO Array were obtained using extensive Monte Carlo simulations performed with a double purpose: (1) to determine the appropriate parameters for the array fitting to the desired range of sensitivity (the knee energy region), and (2) to construct a reliable shower database required for reference in the analysis of experimental data. The AIRES code, with the SIBYLL hadronic collision package, was used to simulate Extended Air Showers produced by primary cosmic rays (assuming protons and iron nuclei), with energies ranging from 10 14 to 10 18 eV. These data were fed into a realistic code which simulates the response of the detectors (water Cherenkov detectors), including the electronics, pickup noise, and the signal attenuation in the connecting cables. The trigger stage was considered in the simulations in order to estimate the trigger efficiency of the array and to verify the accuracy of the reconstruction codes. This paper delineates the simulations performed to obtain the expected behavior of the array, and describes the simulated data. The results of these simulations suggest that we can expect an error in the energy of the primary cosmic-ray of ˜60% of the estimated value and that the error in the measurement of the direction of arrival can be estimated as ˜4°. The present simulations also indicate that unambiguous assignments of the primary energy cannot be obtained because of the uncertainty in the nature of the primary cosmic ray.

    2012-01-01

    The Trick Simulation Environment is a generic simulation toolkit used for constructing and running simulations. This release includes a Monte Carlo analysis simulation framework and a data analysis package. It produces all auto documentation in XML. Also, the software is capable of inserting a malfunction at any point during the simulation. Trick 07 adds variable server output options and error messaging and is capable of using and manipulating wide characters for international support. Wide character strings are available as a fundamental type for variables processed by Trick. A Trick Monte Carlo simulation uses a statistically generated, or predetermined, set of inputs to iteratively drive the simulation. Also, there is a framework in place for optimization and solution finding where developers may iteratively modify the inputs per run based on some analysis of the outputs. The data analysis package is capable of reading data from external simulation packages such as MATLAB and Octave, as well as the common comma-separated values (CSV) format used by Excel, without the use of external converters. The file formats for MATLAB and Octave were obtained from their documentation sets, and Trick maintains generic file readers for each format. XML tags store the fields in the Trick header comments. For header files, XML tags for structures and enumerations, and the members within are stored in the auto documentation. For source code files, XML tags for each function and the calling arguments are stored in the auto documentation. When a simulation is built, a top level XML file, which includes all of the header and source code XML auto documentation files, is created in the simulation directory. Trick 07 provides an XML to TeX converter. The converter reads in header and source code XML documentation files and converts the data to TeX labels and tables suitable for inclusion in TeX documents. A malfunction insertion capability allows users to override the value of any

    2016-04-01

    Rainfall simulation has become an important method for the assessment of soil erosion and soil hydrological processes. For students, rainfall simulation offers an year-round, attractive and active way of experiencing water erosion, while not being dependent on (outdoors) weather conditions. Moreover, using rainfall simulation devices, they can play around with different conditions, including rainfall duration, intensity, soil type, soil cover, soil and water conservation measures, etc. and evaluate their effect on erosion and sediment transport. Rainfall simulators differ in design and scale. At Wageningen University, both BSc and MSc student of the curriculum 'International Land and Water Management' work with different types of rainfall simulation devices in three courses: - A mini rainfall simulator (0.0625m2) is used in the BSc level course 'Introduction to Land Degradation and Remediation'. Groups of students take the mini rainfall simulator with them to a nearby field location and test it for different soil types, varying from clay to more sandy, slope angles and vegetation or litter cover. The groups decide among themselves which factors they want to test and they compare their results and discuss advantage and disadvantage of the mini-rainfall simulator. - A medium sized rainfall simulator (0.238 m2) is used in the MSc level course 'Sustainable Land and Water Management', which is a field practical in Eastern Spain. In this course, a group of students has to develop their own research project and design their field measurement campaign using the transportable rainfall simulator. - Wageningen University has its own large rainfall simulation laboratory, in which a 15 m2 rainfall simulation facility is available for research. In the BSc level course 'Land and Water Engineering' Student groups will build slopes in the rainfall simulator in specially prepared containers. Aim is to experience the behaviour of different soil types or slope angles when (heavy) rain

    Full Text Available In last twenty years, we are seeing increasingly widespread use of simulations in the training of doctors and other professionals of health sciences at the different stages of their educational continuum (undergraduate, postgraduate and continuing medical education. So much so that the concept of simulations-based medical education has emerged and it is now recognized as a vital tool to ensure the learning of medical students and doctors, and to improve patient safety. This article will describe the reasons for the introduction and development of this new methodology, its advantages and the different models and currently available resources. We will describe also the characteristics of so-called simulation centres or clinical skills laboratories that have been developed worldwide, where the simulation-based medical education take place. Moreover, we will refer briefly to the situation in our country and finally to the principles of a good development of the simulation-based medical education.

    Laguna, M Pilar; Hatzinger, Martin; Rassweiler, Jens

    2002-05-01

    Acquisition of skills laboratory training seems to be of importance in the training of surgeons, and is intended to cover the gap between theoretical learning and real practice. Economic and ethical reasons limit the use of animals during the learning process, while trends in medical change have severely restricted the available time to teach and to learn. With the incorporation of laparoscopy and the blossoming of minimally invasive techniques, mainly endoscopy, simulators have gained wide acceptance as an important tool in the surgeon's learning process. Two types of simulators are currently available: inanimates or mannequins and virtual reality simulators. A review of the recent literature shows that there is generally a significant improvement in dexterity after using simulators, whichever type is used. It is still unknown whether training simulation influences the patient's outcome positively.

    This paper presents a model of the artificial ice track in Whistler, Canada that is based on its construction data, and a model of a two-men bobsleigh consisting of nine rigid bodies, having 13 degrees of freedom and incorporating 17 hard frictional contacts. These models are implemented within a simulator that is capable of performing accurate real time simulations of piloted runs on commonly available PC hardware. The simulation is verified against the results of the official two-men race that took place during the Olympic Winter Games in 2010. The simulator has been used by several professional Swiss pilots during their preparation for the 2014 Olympic Winter Games in Sochi, Russia. The simulator is exploited to analyse and judge the range of possible driving lines regarding speed and runtime improvements. It could also serve to consult track designers about safety issues and sleigh constructors about the expected dynamics on a track.

    2007-05-01

    The quality of education, CPR guidelines and the chain of survival all contribute to patient outcome following cardiac arrest. Increasing concerns about patient safety have focused attention on the methods used to train and prepare doctors for clinical practice. Reductions in clinical exposure at both undergraduate and postgraduate level have been implicated in junior doctors inability to recognise and manage critically ill patients. Simulation is used as a central training tool in contemporary advanced life support teaching. Simulation provides a learning opportunity for controlled clinical practice without putting patients or others at risk. This review examines the history and rationale for simulation training in resuscitation and provides some background to the learning theories that underpin it. The role of task trainers, high and low fidelity patient simulators and computer assisted simulation as teaching tools are discussed.

  4. Educational science meets simulation.

    Pasquale, Susan J

    2015-03-01

    With the increased use of simulation to teach the knowledge and skills demanded of clinical practice, toward the achievement of optimal patient care outcomes, it becomes increasingly important that clinician educators have fundamental knowledge about educational science and its applications to teaching and learning. As the foremost goal of teaching is to facilitate learning, it is essential that the simulation experience be oriented to the learning process. In order for this to occur, is it necessary for the clinician educator to understand the fundamentals of educational science and theories of education such that they can apply them to teaching and learning in an environment focused on medical simulation. Underscoring the rationale for the fundamentals of educational science to be applied to the simulation environment, and to work in tandem with simulation, is the importance that accurate and appropriate information is retained and applied toward establishing competence in essential practice-based skills and procedures.

    2005-04-12

    We present the application of hardware accelerated volume rendering algorithms to the simulation of radiographs as an aid to scientists designing experiments, validating simulation codes, and understanding experimental data. The techniques presented take advantage of 32 bit floating point texture capabilities to obtain validated solutions to the radiative transport equation for X-rays. An unsorted hexahedron projection algorithm is presented for curvilinear hexahedra that produces simulated radiographs in the absorption-only regime. A sorted tetrahedral projection algorithm is presented that simulates radiographs of emissive materials. We apply the tetrahedral projection algorithm to the simulation of experimental diagnostics for inertial confinement fusion experiments on a laser at the University of Rochester. We show that the hardware accelerated solution is faster than the current technique used by scientists.

    The ew uav has entered combat, and in local warfare carries out the electronic reconnaissance, jamming anti - radiation attacks and battlefield target mutilate assessment and many kinds of operational missions. When a uav is in cruise state, the flight level is basically stable, so in executing communications detection task, the detection distance to radio, mobile phones and other communication equipment can be predicted. This paper aims at two cruise ways including high altitude and the hollow. Based on two indexes of signal - to - noise ratio ( SNR) and stadia, to communication detection distance is computated simulatively with MATLAB. The simulation results can be used as credible basis tactics of communication countermeasure research.%电子战无人机已进入战场,并在局部战争中遂行了电子侦察、电子干扰、反辐射攻击以及战场目标毁伤评估等多种作战任务.无人机在巡航状态,飞行高度基本稳定,因此在执行通信侦测任务时,对电台、手机等通信设备的侦测距离可以预测.针对高空和中空两种巡航方式,以信噪比(SNR)及视距两项指标为依据,用MATLAB对通信侦测距离进行了仿真计算,仿真结果可以做为通信对抗战术研究的可信依据.

  8. Adiabatic quantum simulators

    Directory of Open Access Journals (Sweden)

    J. D. Biamonte

    2011-06-01

    Full Text Available In his famous 1981 talk, Feynman proposed that unlike classical computers, which would presumably experience an exponential slowdown when simulating quantum phenomena, a universal quantum simulator would not. An ideal quantum simulator would be controllable, and built using existing technology. In some cases, moving away from gate-model-based implementations of quantum computing may offer a more feasible solution for particular experimental implementations. Here we consider an adiabatic quantum simulator which simulates the ground state properties of sparse Hamiltonians consisting of one- and two-local interaction terms, using sparse Hamiltonians with at most three-local interactions. Properties of such Hamiltonians can be well approximated with Hamiltonians containing only two-local terms. The register holding the simulated ground state is brought adiabatically into interaction with a probe qubit, followed by a single diabatic gate operation on the probe which then undergoes free evolution until measured. This allows one to recover e.g. the ground state energy of the Hamiltonian being simulated. Given a ground state, this scheme can be used to verify the QMA-complete problem LOCAL HAMILTONIAN, and is therefore likely more powerful than classical computing.

    Simulation is a frontier for disseminating knowledge in almost all the fields of medicine and it is attracting growing interest because it offers a means of developing new teaching and training models, as well as of verifying what has been learned in a critical setting that simulates clinical practice. The role of simulation in neurology, until now limited by the obvious physical limitations of the dummies used to train students and learners, is now increasing since, today, it allows anamnestic data to be related to the instrumental evidence necessary for diagnosis and therapeutic decision-making, i.e., to the findings of neurophysiological investigations (EEG, carotid and vertebral echography and transcranial Doppler, for example) and neuroradiological investigations (CT, MRI imaging), as well as vital parameter monitoring (ECG, saturimetry, blood pressure, respiratory frequency, etc.). Simulation, by providing learners with opportunities to discuss, with experts, different profiles of biological parameters (both during the simulation itself and in the subsequent debriefing session), is becoming an increasingly important tool for training those involved in evaluation of critical neurological patients (stroke, Guillan Barrè syndrome, myasthenia, status epilepticus, headache, vertigo, confusional status, etc.) and complex cases. In this SIMMED (Italian Society for Simulation in Medicine) position paper, the applications (present and, possibly, future) of simulation in neurology are reported.

    Obstetrical emergencies require the rapid formation of a team with clear communication, strong leadership, and appropriate decision-making to ensure a positive patient outcome. Obstetric teams can improve their emergency response capability and efficiency through team and simulation training. Postpartum hemorrhage is an ideal model for team and simulation training, as postpartum hemorrhage requires a multidisciplinary team with the capability to produce a protocol-driven, rapid response. This article provides an overview of team and simulation training and focuses on applications within obstetrics, particularly preparation for postpartum hemorrhage.

    Molecular dynamic (MD) provided an ab initio simulation for nano-scale mechanical behavior of materials, provided that the inter-atomic potential is accurately prescribed. MD is particularly suitable in simulating the formation, the deformation, and the evolution of nanocrystals under a fast strain rate. To tackle large scale system and nano-seconds time duration, parallel algorithm is desired. The present paper reviews the recent advances in MD simulation for nanocrystals with attention focused on the applications toward nanomechanics. The examined issues are: formation of nanocrystalline metals, nanoindentation on nanocrystals, fast deformation of nanocrystals, orderdisorder transition, and nano-particle impact.

    We present a method to simulate the flow past bioinspired swimmers starting from pictures of an actual fish. The overall approach requires i) a skeleton graph generation to get a level-set function from pictures; ii) optimal transportation to obtain the velocity on the body surface; iii) flow simulations realized with a Cartesian method based on penalization. This technique can be used to automate modeling swimming motion from data collected by biologists. We illustrate this paradigm by simulating the swimming of a mackerel fish.

Self-orgainizing properties of systems coupling simulated and calculated probabilities and their link to quantum computations are discussed. Special attention was focused upon coupled stochastic processes, defined in terms of conditional probabilities, for which joint probability does not exist.

    Energy Technology Data Exchange (ETDEWEB)

    Acken, J. M.; Goldstein, L. H.

    1980-01-01

    As digital integrated circuit size and complexity increases, the need for accurate and efficient computer simulation increases. Logic simulators such as SALOGS (SAndia LOGic Simulator), which utilize transition states in addition to the normal stable states, provide more accurate analysis than is possible with traditional logic simulators. Furthermore, the computational complexity of this analysis is far lower than that of circuit simulation such as SPICE. An eight-value logic simulation environment allows the use of accurate delay models that incorporate both element response and transition times. Thus, timing simulation with an accuracy approaching that of circuit simulation can be accomplished with an efficiency comparable to that of logic simulation. 4 figures.

    2011-01-01

    This paper discusses the latest generation of the MONARC (MOdels of Networked Analysis at Regional Centers) simulation framework, as a design and modelling tool for large scale distributed systems applied to HEP experiments. A process-oriented approach for discrete event simulation is well-suited for describing concurrent running programs, as well as the stochastic arrival patterns that characterize how such systems are used. The simulation engine is based on Threaded Objects (or Active Objects), which offer great flexibility in simulating the complex behavior of distributed data processing programs. The engine provides an appropriate scheduling mechanism for the Active objects with support for interrupts. This approach offers a natural way of describing complex running programs that are data dependent and which concurrently compete for shared resources as well as large numbers of concurrent data transfers on shared resources. The framework provides a complete set of basic components (processing nodes, data s...

    This paper presents the simulation of the GLAST high energy gamma-ray telescope. The simulation package, written in C++, is based on the Geant4 toolkit, and it is integrated into a general framework used to process events. A detailed simulation of the electronic signals inside Silicon detectors has been provided and it is used for the particle tracking, which is handled by a dedicated software. A unique repository for the geometrical description of the detector has been realized using the XML language and a C++ library to access this information has been designed and implemented. As first application of the GLAST LAT software, one day of simulated data has been produced. This paper outlines the contribution developed by the Italian GLAST software group.

    1997-01-01

    We describe cosmological simulation techniques and their application to studies of cosmic structure formation, with particular attention to recent hydrodynamic simulations of structure in the high redshift universe. Collisionless N-body simulations with Gaussian initial conditions produce a pattern of sheets, filaments, tunnels, and voids that resembles the observed large scale galaxy distribution. Simulations that incorporate gas dynamics and dissipation form dense clumps of cold gas with sizes and masses similar to the luminous parts of galaxies. Models based on inflation and cold dark matter predict a healthy population of high redshift galaxies, including systems with star formation rates of 20 M_{\\sun}/year at z=6. At z~3, most of the baryons in these models reside in the low density intergalactic medium, which produces fluctuating Lyman-alpha absorption in the spectra of background quasars. The physical description of this ``Lyman-alpha forest'' is particularly simple if the absorption spectrum is viewe...

    Science.gov (United States)

    Bauleo, P.; Bonifazi, C.; Filevich, A.

    The angular and energy resolution of the TANGO Array has been obtained using Monte Carlo simulations. The AIRES code, with the SYBILL hadronic collision package, was used to simulate Extended Air Showers produced by primary cosmic rays (protons and iron nuclei), with energies ranging from 1014 eV to 1018 eV. These data were fed into a realistic code which simulates the response of the detector stations (water ˇCerenkov detectors), including the electronics, pick up noise, and the signal attenuation in the connecting cabling. The trigger stage is taken into account in order to produce estimates of the trigger efficiency of the array and to check the accuracy of the reconstruction codes. This paper describes the simulations performed to obtain the expected behavior of the array, and presents the simulated data. These simulations indicate that the accuracy of the cosmic ray primary energy determination is expected to be ˜ 60 % and the precision in the measurement of the direction of arrival can be estimated as ˜ 4 degrees.

  9. Converting DYNAMO simulations to Powersim Studio simulations

    Energy Technology Data Exchange (ETDEWEB)

    Walker, La Tonya Nicole; Malczynski, Leonard A.

    2014-02-01

    DYNAMO is a computer program for building and running 'continuous' simulation models. It was developed by the Industrial Dynamics Group at the Massachusetts Institute of Technology for simulating dynamic feedback models of business, economic, and social systems. The history of the system dynamics method since 1957 includes many classic models built in DYANMO. It was not until the late 1980s that software was built to take advantage of the rise of personal computers and graphical user interfaces that DYNAMO was supplanted. There is much learning and insight to be gained from examining the DYANMO models and their accompanying research papers. We believe that it is a worthwhile exercise to convert DYNAMO models to more recent software packages. We have made an attempt to make it easier to turn these models into a more current system dynamics software language, Powersim © Studio produced by Powersim AS2 of Bergen, Norway. This guide shows how to convert DYNAMO syntax into Studio syntax.

    Energy Technology Data Exchange (ETDEWEB)

    Pronskikh, V. S. [Fermilab

    2014-05-09

    Verification and validation of computer codes and models used in simulation are two aspects of the scientific practice of high importance and have recently been discussed by philosophers of science. While verification is predominantly associated with the correctness of the way a model is represented by a computer code or algorithm, validation more often refers to model’s relation to the real world and its intended use. It has been argued that because complex simulations are generally not transparent to a practitioner, the Duhem problem can arise for verification and validation due to their entanglement; such an entanglement makes it impossible to distinguish whether a coding error or model’s general inadequacy to its target should be blamed in the case of the model failure. I argue that in order to disentangle verification and validation, a clear distinction between computer modeling (construction of mathematical computer models of elementary processes) and simulation (construction of models of composite objects and processes by means of numerical experimenting with them) needs to be made. Holding on to that distinction, I propose to relate verification (based on theoretical strategies such as inferences) to modeling and validation, which shares the common epistemology with experimentation, to simulation. To explain reasons of their intermittent entanglement I propose a weberian ideal-typical model of modeling and simulation as roles in practice. I suggest an approach to alleviate the Duhem problem for verification and validation generally applicable in practice and based on differences in epistemic strategies and scopes

  12. Multilevel turbulence simulations

    Energy Technology Data Exchange (ETDEWEB)

    Tziperman, E. [Princeton Univ., NJ (United States)

    1994-12-31

    The authors propose a novel method for the simulation of turbulent flows, that is motivated by and based on the Multigrid (MG) formalism. The method, called Multilevel Turbulence Simulations (MTS), is potentially more efficient and more accurate than LES. In many physical problems one is interested in the effects of the small scales on the larger ones, or in a typical realization of the flow, and not in the detailed time history of each small scale feature. MTS takes advantage of the fact that the detailed simulation of small scales is not needed at all times, in order to make the calculation significantly more efficient, while accurately accounting for the effects of the small scales on the larger scale of interest. In MTS, models of several resolutions are used to represent the turbulent flow. The model equations in each coarse level incorporate a closure term roughly corresponding to the tau correction in the MG formalism that accounts for the effects of the unresolvable scales on that grid. The finer resolution grids are used only a small portion of the simulation time in order to evaluate the closure terms for the coarser grids, while the coarse resolution grids are then used to accurately and efficiently calculate the evolution of the larger scales. The methods efficiency relative to direct simulations is of the order of the ratio of required integration time to the smallest eddies turnover time, potentially resulting in orders of magnitude improvement for a large class of turbulence problems.

  13. DSN Array Simulator

    Tikidjian, Raffi; Mackey, Ryan

    2008-01-01

    The DSN Array Simulator (wherein 'DSN' signifies NASA's Deep Space Network) is an updated version of software previously denoted the DSN Receive Array Technology Assessment Simulation. This software (see figure) is used for computational modeling of a proposed DSN facility comprising user-defined arrays of antennas and transmitting and receiving equipment for microwave communication with spacecraft on interplanetary missions. The simulation includes variations in spacecraft tracked and communication demand changes for up to several decades of future operation. Such modeling is performed to estimate facility performance, evaluate requirements that govern facility design, and evaluate proposed improvements in hardware and/or software. The updated version of this software affords enhanced capability for characterizing facility performance against user-defined mission sets. The software includes a Monte Carlo simulation component that enables rapid generation of key mission-set metrics (e.g., numbers of links, data rates, and date volumes), and statistical distributions thereof as functions of time. The updated version also offers expanded capability for mixed-asset network modeling--for example, for running scenarios that involve user-definable mixtures of antennas having different diameters (in contradistinction to a fixed number of antennas having the same fixed diameter). The improved version also affords greater simulation fidelity, sufficient for validation by comparison with actual DSN operations and analytically predictable performance metrics.

  14. Simulations of Granular Media

    Science.gov (United States)

    Herrmann, H. J.; Müller, M.

    For the last ten years there has been an enormous progress in the simulation of granular media like sand or powders. These simulations consist in simulating trajectories of each particle individually. Essentially one has to solve the Newton's equations including the effects of Coulomb friction and the physics occuring at a collision. But the details of the trajectories are not important for the collective behaviour. Therefore simplifications are introduced on the smallest scales. I will introduce various methods like molecular dynamics that are used to simulate large amounts of particles (over 109). Some of these medhods are based on the exploitation of parallelisation and metacomputing. Other approaches are more stochastic (DSMC Direct Simulation Monte Carlo) which simplify the calculation of collisions, positions and collision times. Very successful has been also the use of cellular automata which have been able to predict details such as the logarithmic tale of sand heaps. I will also discuss numerical techniques used for the surrounding fluid. This can be water in the case of sedimentation or air when one studies the formation of dunes in the desert. The calculation of velocity and pressure field of the fluid are done using multigrid techniques on parallel computers. We will compare the performance of the various techniques and show some benchmarks on the dependence on the size of the system, the density of particles and the number of processors used.

    1989-01-01

    The Orbital Maneuvering Vehicle (OMV) will be remotely piloted during rendezvous, docking, or proximity operations with target spacecraft from a ground control console (GCC). The real-time mission simulator and graphics being used to design a console pilot-machine interface are discussed. A real-time orbital dynamics simulator drives the visual displays. The dynamics simulator includes a J2 oblate earth gravity model and a generalized 1962 rotating atmospheric and drag model. The simulator also provides a variable-length communication delay to represent use of the Tracking and Data Relay Satellite System (TDRSS) and NASA Communications (NASCOM). Input parameter files determine the graphics display. This feature allows rapid prototyping since displays can be easily modified from pilot recommendations. A series of pilot reviews are being held to determine an effective pilot-machine interface. Pilots fly missions with nominal to 3-sigma dispersions in translational or rotational axes. Console dimensions, switch type and layout, hand controllers, and graphic interfaces are evaluated by the pilots and the GCC simulator is modified for subsequent runs. Initial results indicate a pilot preference for analog versus digital displays and for two 3-degree-of-freedom hand controllers.

    Full Text Available The classical (boolean notion of refinement for behavioral interfaces of system components is the alternating refinement preorder. In this paper, we define a distance for interfaces, called interface simulation distance. It makes the alternating refinement preorder quantitative by, intuitively, tolerating errors (while counting them in the alternating simulation game. We show that the interface simulation distance satisfies the triangle inequality, that the distance between two interfaces does not increase under parallel composition with a third interface, and that the distance between two interfaces can be bounded from above and below by distances between abstractions of the two interfaces. We illustrate the framework, and the properties of the distances under composition of interfaces, with two case studies.

    2011-01-01

    Joint experimentation that investigates sensor optimization, re-tasking and management has far reaching implications for Department of Defense, Interagency and multinational partners. An adaption of traditional human in the loop (HITL) Modeling and Simulation (M&S) was one approach used to generate the findings necessary to derive and support these implications. Here an entity-based simulation was re-engineered to run on USJFCOM's High Performance Computer (HPC). The HPC was used to support the vast number of constructive runs necessary to produce statistically significant data in a timely manner. Then from the resulting sensitivity analysis, event designers blended the necessary visualization and decision making components into a synthetic environment for the HITL simulations trials. These trials focused on areas where human decision making had the greatest impact on the sensor investigations. Thus, this paper discusses how re-engineering existing M&S for constructive applications can positively influence the design of an associated HITL experiment.

We consider the distribution of real galaxy morphologies in shapelet parameter space, then resample this distribution to generate new galaxies. The simulated objects include realistic spiral arms, bars, discs, arbitrary radial profiles and even dust lanes or knots. We apply standard morphology diagnostics to demonstrate that our artificial images closely mimic real data in terms of galaxy size, concentration and asymmetry statistics, etc. Observational effects, including Point-Spread Function, noise, pixellisation, and astrometric distortions are also modelled. Sample images are made available on the world wide web. These simulations are useful to develop and test precision image analysis techniques, including photometry, astrometry, and shape me...

    2016-01-01

    This position with the Simulation and Graphics Branch (ER7) at Johnson Space Center (JSC) provided an introduction to vehicle hardware, mission planning, and simulation design. ER7 supports engineering analysis and flight crew training by providing high-fidelity, real-time graphical simulations in the Systems Engineering Simulator (SES) lab. The primary project assigned by NASA mentor and SES lab manager, Meghan Daley, was to develop a graphical simulation of the rendezvous, proximity operations, and docking (RPOD) phases of flight. The simulation is to include a generic crew/cargo transportation vehicle and a target object in low-Earth orbit (LEO). Various capsule, winged, and lifting body vehicles as well as historical RPOD methods were evaluated during the project analysis phase. JSC core mission to support the International Space Station (ISS), Commercial Crew Program (CCP), and Human Space Flight (HSF) influenced the project specifications. The simulation is characterized as a 30 meter +V Bar and/or -R Bar approach to the target object's docking station. The ISS was selected as the target object and the international Low Impact Docking System (iLIDS) was selected as the docking mechanism. The location of the target object's docking station corresponds with the RPOD methods identified. The simulation design focuses on Guidance, Navigation, and Control (GNC) system architecture models with station keeping and telemetry data processing capabilities. The optical and inertial sensors, reaction control system thrusters, and the docking mechanism selected were based on CCP vehicle manufacturer's current and proposed technologies. A significant amount of independent study and tutorial completion was required for this project. Multiple primary source materials were accessed using the NASA Technical Report Server (NTRS) and reference textbooks were borrowed from the JSC Main Library and International Space Station Library.

    Full Text Available Brian is a simulator for spiking neural networks (http://www.briansimulator.org. The focus is on making the writing of simulation code as quick and easy as possible for the user, and on flexibility: new and non-standard models are no more difficult to define than standard ones. This allows scientists to spend more time on the details of their models, and less on their implementation. Neuron models are defined by writing differential equations in standard mathematical notation, facilitating scientific communication. Brian is written in the Python programming language, and uses vector-based computation to allow for efficient simulations. It is particularly useful for neuroscientific modelling at the systems level, and for teaching computational neuroscience.

  5. Simulations of vortex generators

    Science.gov (United States)

    Koumoutsakos, P.

    1995-01-01

    We are interested in the study, via direct numerical simulations, of active vortex generators. Vortex generators may be used to modify the inner part of the boundary layer or to control separation thus enhancing the performance and maneuverability of aerodynamic configurations. We consider generators that consist of a surface cavity elongated in the stream direction and partially covered with a moving lid that at rest lies flush with the boundary. Streamwise vorticity is generated and ejected due to the oscillatory motion of the lid. The present simulations complement relevant experimental investigations of active vortex generators at NASA Ames and Stanford University (Saddoughi, 1994, and Jacobson and Reynolds, 1993). Jacobson and Reynolds (1993) used a piezoelectric device in water, allowing for small amplitude high frequency oscillations. They placed the lid asymmetrically on the cavity and observed a strong outward velocity at the small gap of the cavity. Saddoughi used a larger mechanically driven device in air to investigate this flow and he observed a jet emerging from the wide gap of the configuration, contrary to the findings of Jacobson and Reynolds. Our task is to simulate the flows generated by these devices and to conduct a parametric study that would help us elucidate the physical mechanisms present in the flow. Conventional computational schemes encounter difficulties when simulating flows around complex configurations undergoing arbitrary motions. Here we present a formulation that achieves this task on a purely Lagrangian frame by extending the formulation presented by Koumoutsakos, Leonard and Pepin (1994). The viscous effects are taken into account by modifying the strength of the particles, whereas fast multipole schemes employing hundreds of thousands of particles allow for high resolution simulations. The results of the present simulations would help us assess some of the effects of three-dimensionality in experiments and investigate the role

    This topic for debate explores how simulation based education has become an area where Higher Education providers look to deliver on an agenda of recruiting, educating and assessing for compassion. This paper offers that rather than SBE being a forum for developing and promoting compassion it may actually be achieving the opposite both for those we educate and those they in turn care for. It does this through introducing two ideas, near enemies and Jung's shadow and uses these ideas to explore our understanding and expression of compassion through simulation.

    Emotional intelligence (EI) is an established concept in the business literature with evidence that it is an important factor in determining career achievement. There is increasing interest in the role that EI has in medical training, but it is still a nascent field. This article reviews the EI literature most relevant to surgical training and proposes that simulation offers many benefits to the development of EI. Although there are many unanswered questions, it is expected that future research will demonstrate the effectiveness of using simulation to develop EI within surgery. Copyright © 2015 Elsevier Inc.

    The Terascale Optimal PDE Solvers (TOPS) Integrated Software Infrastructure Center (ISIC) was created to develop and implement algorithms and support scientific investigations performed by DOE-sponsored researchers. These simulations often involve the solution of partial differential equations (PDEs) on terascale computers. The TOPS Center researched, developed and deployed an integrated toolkit of open-source, optimal complexity solvers for the nonlinear partial differential equations that arise in many DOE application areas, including fusion, accelerator design, global climate change and reactive chemistry. The algorithms created as part of this project were also designed to reduce current computational bottlenecks by orders of magnitude on terascale computers, enabling scientific simulation on a scale heretofore impossible.

    1992-03-01

    A discrete-time simulation model of carcinogenesis is described mathematically using recursive relationships between time-varying model variables. The dynamics of cellular behavior is represented within a biological framework that encompasses two irreversible and heritable genetic changes. Empirical data and biological supposition dealing with both control and experimental animal groups are used together to establish values for model input variables. The estimation of these variables is integral to the simulation process as described in step-by-step detail. Hepatocarcinogenesis in male F344 rats provides the basis for seven modeling scenarios which illustrate the complexity of relationships among cell proliferation, genotoxicity, and tumor risk.

    The historical roots of simulation might be described with the broadest definition of medical simulation: "an imitation of some real thing, state of affairs, or process" for the practice of skills, problem solving, and judgment. From the first "blue box" flight simulator to the military's impetus in the transfer of modeling and simulation technology to medicine, worldwide acceptance of simulation training is growing. Large collaborative simulation centers support the expectation of increases in multidisciplinary, interprofessional, and multimodal simulation training. Virtual worlds, both immersive and Web-based, are at the frontier of innovation in medical education.

    The object of the 'Enabling Immersive Simulation for Complex Systems Analysis and Training' LDRD has been to research, design, and engineer a capability to develop simulations which (1) provide a rich, immersive interface for participation by real humans (exploiting existing high-performance game-engine technology wherever possible), and (2) can leverage Sandia's substantial investment in high-fidelity physical and cognitive models implemented in the Umbra simulation framework. We report here on these efforts. First, we describe the integration of Sandia's Umbra modular simulation framework with the open-source Delta3D game engine. Next, we report on Umbra's integration with Sandia's Cognitive Foundry, specifically to provide for learning behaviors for 'virtual teammates' directly from observed human behavior. Finally, we describe the integration of Delta3D with the ABL behavior engine, and report on research into establishing the theoretical framework that will be required to make use of tools like ABL to scale up to increasingly rich and realistic virtual characters.

    2012-10-01

    We have simulated an existing experimental design to determine the resolution improvement upon energy measurements of neutron unbound nuclei. A number of experiments of this type have been performed at the National Superconducting Cyclotron Laboratory (NSCL), located at Michigan State University. An excited nucleus is typically produced with a radioactive beam interacting with a passive Beryllium target. Many different nuclei are produced in experiment, each of which immediately decays into a charged particle and neutron. The charged particles are detected and the neutrons interact in scintillation detectors such as the Modular Neutron Array (MoNA) and Large Multi-Institutional Scintillation Array (LISA). In our simulation, we have constructed an active target that provides additional information such that the point of nuclear interaction within the target may be determined. This information improves the resolution in decay energy measurements of neutron unbound isotopes. This presentation will cover some aspects of the simulation process, as well as showing some of the results that demonstrate the simulated improvement over a passive target.

    The LHCb Grid access if based on the LHCbDirac system. It provides access to data and computational resources to researchers with different geographical locations. The Grid has a hierarchical topology with multiple sites distributed over the world. The sites differ from each other by their number of CPUs, amount of disk storage and connection bandwidth. These parameters are essential for the Grid work. Moreover, job scheduling and data distribution strategy have a great impact on the grid performance. However, it is hard to choose an appropriate algorithm and strategies as they need a lot of time to be tested on the real grid. In this study, we describe the LHCb Grid simulator. The simulator reproduces the LHCb Grid structure with its sites and their number of CPUs, amount of disk storage and bandwidth connection. We demonstrate how well the simulator reproduces the grid work, show its advantages and limitations. We show how well the simulator reproduces job scheduling and network anomalies, consider methods ...

  13. Simulating solar MHD

    Directory of Open Access Journals (Sweden)

    M. Schüssler

    Full Text Available Two aspects of solar MHD are discussed in relation to the work of the MHD simulation group at KIS. Photospheric magneto-convection, the nonlinear interaction of magnetic field and convection in a strongly stratified, radiating fluid, is a key process of general astrophysical relevance. Comprehensive numerical simulations including radiative transfer have significantly improved our understanding of the processes and have become an important tool for the interpretation of observational data. Examples of field intensification in the solar photosphere ('convective collapse' are shown. The second line of research is concerned with the dynamics of flux tubes in the convection zone, which has far-reaching implications for our understanding of the solar dynamo. Simulations indicate that the field strength in the region where the flux is stored before erupting to form sunspot groups is of the order of 105 G, an order of magnitude larger than previous estimates based on equipartition with the kinetic energy of convective flows.

    1993-01-01

    The Data System Dynamic Simulator (DSDS) is a discrete event simulation tool. It was developed for NASA for the specific purpose of evaluating candidate architectures for data systems of the Space Station era. DSDS provides three methods for meeting this requirement. First, the user has access to a library of standard pre-programmed elements. These elements represent tailorable components of NASA data systems and can be connected in any logical manner. Secondly, DSDS supports the development of additional elements. This allows the more sophisticated DSDS user the option of extending the standard element set. Thirdly, DSDS supports the use of data streams simulation. Data streams is the name given to a technique that ignores packet boundaries, but is sensitive to rate changes. Because rate changes are rare compared to packet arrivals in a typical NASA data system, data stream simulations require a fraction of the CPU run time. Additionally, the data stream technique is considerably more accurate than another commonly-used optimization technique.

    2007-01-01

    (Abridged) We use 3D SPH calculations with higher resolution, as well as with more realistic viscosity and sound-speed prescriptions than previous work to examine the eccentric instability which underlies the superhump phenomenon in semi-detached binaries. We illustrate the importance of the two-armed spiral mode in the generation of superhumps. Differential motions in the fluid disc cause converging flows which lead to strong spiral shocks once each superhump cycle. The dissipation associated with these shocks powers the superhump. We compare 2D and 3D results, and conclude that 3D simulations are necessary to faithfully simulate the disc dynamics. We ran our simulations for unprecedented durations, so that an eccentric equilibrium is established except at high mass ratios where the growth rate of the instability is very low. Our improved simulations give a closer match to the observed relationship between superhump period excess and binary mass ratio than previous numerical work. The observed black hole X-r...

    A generalized model of a FASTBUS master is presented. The model is used with simulation tools to aid in the specification, design, and production of FASTBUS slave modules. The model provides a mechanism to interact with the electrical schematics and software models to predict performance. The model is written in the IEEE std 1076-1987 hardware description language VHDL. A model of the ATC logic is also presented. VHDL was chosen to provide portability to various platforms and simulation tools. The models, in conjunction with most commercially available simulators, will perform all of the transactions specified in IEEE std 960-1989. The models may be used to study the behavior of electrical schematics and other software models and detect violations of the FASTBUS protocol. For example, a hardware design of a slave module could be studied, protocol violations detected and corrected before committing money to prototype development. The master model accepts a stream of high level commands from an ASCII file to initiate FASTBUS transactions. The high level command language is based on the FASTBUS standard routines listed in IEEE std 1177-1989. Using this standard-based command language to direct the model of the master, hardware engineers can simulate FASTBUS transactions in the language used by physicists and programmers to operate FASTBUS systems. 15 refs., 6 figs.

    The NASA Glenn Research Center, in partnership with the aerospace industry, other government agencies, and academia, is leading the effort to develop an advanced multidisciplinary analysis environment for aerospace propulsion systems called the Numerical Propulsion System Simulation (NPSS). NPSS is a framework for performing analysis of complex systems. The initial development of NPSS focused on the analysis and design of airbreathing aircraft engines, but the resulting NPSS framework may be applied to any system, for example: aerospace, rockets, hypersonics, power and propulsion, fuel cells, ground based power, and even human system modeling. NPSS provides increased flexibility for the user, which reduces the total development time and cost. It is currently being extended to support the NASA Aeronautics Research Mission Directorate Fundamental Aeronautics Program and the Advanced Virtual Engine Test Cell (AVETeC). NPSS focuses on the integration of multiple disciplines such as aerodynamics, structure, and heat transfer with numerical zooming on component codes. Zooming is the coupling of analyses at various levels of detail. NPSS development includes capabilities to facilitate collaborative engineering. The NPSS will provide improved tools to develop custom components and to use capability for zooming to higher fidelity codes, coupling to multidiscipline codes, transmitting secure data, and distributing simulations across different platforms. These powerful capabilities extend NPSS from a zero-dimensional simulation tool to a multi-fidelity, multidiscipline system-level simulation tool for the full development life cycle.

    'Everything that living things do can be understood in terms of the jigglings and wigglings of atoms' as Richard Feynman provocatively stated nearly 50 years ago. But how can we 'see' this wiggling and jiggling and understand how it drives biology? Increasingly, computer simulations of biological macromolecules are helping to meet this challenge.

    2010-05-01

    Laboratory simulations of the Martian surface are of importance to broaden scientific understanding of the physical processes, but also in order to develop the technology necessary for exploration of the planet. The Mars Simulation Laboratory at Aarhus University [1] has been involved in such simulations for around ten years and has developed several experimental facilities for carrying out science or instrument testing under conditions similar to those at the Martian surface, specifically low pressure, low temperature and importantly recreating the wind flow environment and dust suspension (reproducing the Martian dusty aerosol) using Mars analogue material [2]. The science involved in this simulation work has covered a broad spectrum including, erosion induced mineralogy/chemistry, particulate electrification, magnetic properties of Martian dust, biological survival, UV induced chemistry/mineralogy (using a solar simulator), adhesion/cohesion processes and the wind driven transport of dust and sand [3,4]. With regard to technology the wind tunnel facilities have been used in the development of the latest wind and dust sensing instrumentation [5,6]. With support from the European Space Agency (ESA) and Danish national funding an advanced Mars simulation facility has recently been constructed (2009). This wind tunnel facility has a cross section of 2 x 1 m and a length of 8 m, a temperature range down to below -120C, wind speeds in excess of 20m/s, and automated dust control. With a range of (specialised) sensing instrumentation it provides the opportunity to perform a new generation of scientific experiments and allow testing and technology development in the most realistic and rigorous environment. As well as being available for the space agencies, this facility will be open to all potential scientific collaborators. Also European planetary scientists may benefit from support through the EU Europlanet FP7 networking programme. For more information on access

[Adapted from Szente et al. 2017]How do jets emitted from the Suns surface contribute to its corona and to the solar wind? In a recent study, a team of scientists performed complex three-dimensional simulations of coronal jets to answer these questions.Small ExplosionsCoronal jets are relatively small eruptions from the Suns surface, with heights of roughly 100 to 10,000 km, speeds of 10 to 1,000 km/s, and lifetimes of a few minutes to around ten hours. These jets are constantly present theyre emitted even from the quiet Sun, when activity is otherwise low and weve observed them with a fleet of Sun-watching space telescopes spanning the visible, extreme ultraviolet (EUV), and X-ray wavelength bands.A comparison of simulated observations based on the authors model (left panels) to actual EUV and X-ray observations of jets (right panels). [Szente et al. 2017]Due to their ubiquity, we speculate that these jets might contribute to heating the global solar corona (which is significantly hotter than the surface below it, a curiosity known as the coronal heating problem). We can also wonder what role these jets might play in driving the overall solar wind.Launching a JetLed by Judit Szente (University of Michigan), a team of scientists has explored the impact of coronal jets on the global corona and solar wind with a series of numerical simulations. Szente and collaborators used three-dimensional, magnetohydrodynamic simulations that provide realistic treatment of the solar atmosphere, the solar wind acceleration, and the complexities of heat transfer throughout the corona.In the authors simulations, a jet is initiated as a magnetic dipole rotates at the solar surface, winding up field lines. Magnetic reconnection between the twisted lines and the background field then launches the jet from the dense and hot solar

    The human patient simulator or high-fidelity mannequin has become synonymous with the word simulation in nursing education. Founded on a historical context and on an evaluation of the current application of simulation in nursing education, this article challenges that assumption as limited and restrictive. A definition of simulation and a broader conceptualization of its application in nursing education are presented. The need for an ideological basis for simulation in nursing education is highlighted. The call is made for theory to answer the question of why simulation is used in nursing to anchor its proper and effective application in nursing education.

  14. Simulation of the Vacuum Assisted Resin Transfer Molding (VARTM) process and the development of light-weight composite bridging

    Science.gov (United States)

    Robinson, Marc J.

    A continued desire for increased mobility in the aftermath of natural disasters, or on the battlefield, has lead to the need for improved light-weight bridging solutions. This research investigates the development of a carbon/epoxy composite bridging system to meet the needs for light-weight bridging. The research focuses on two main topics. The first topic is that of processing composite structures and the second is the design and testing of these structures. In recent years the Vacuum Assisted Resin Transfer Molding (VARTM) process has become recognized as a low-cost manufacturing alternative for large Fiber Reinforced Polymer (FRP) composite structures for civil, military, and aerospace applications. The success of the VARTM process (complete wet-out) is very sensitive to the resin injection strategy used and the proper placement of flow distribution materials and inlet and vacuum ports. Predicting the flow front pattern, the time required for infusing a part with resin, and the time required to bleed excess resin at the end of filling, is critical to ensure that the part will become completely impregnated and desired fiber volume fractions achieved prior to the resin gelling (initiation of cure). In order to eliminate costly trial and error experiments to determine the optimal infusion strategy, this research presents a simulation model which considers in-plane flow as well as flow through the thickness of the preform. In addition to resin filling, the current model is able to simulate the bleeding of resin at the end of filling to predict the required bleeding time to reach desired fiber volume fractions for the final part. In addition to processing, the second portion of the dissertation investigates the design and testing of composite bridge deck sections which also serve as short-span bridging for gaps up to 4 m in length. The research focuses on the design of a light-weight core material for bridge decking as well as proof loading of short-span bridge

    This report describes simulant development work that was conducted to support the technology maturation of the LAWPS facility. Desired simulant physical properties (density, viscosity, solids concentration, solid particle size), sodium concentrations, and general anion identifications were provided by WRPS. The simulant recipes, particularly a “nominal” 5.6M Na simulant, are intended to be tested at several scales, ranging from bench-scale (500 mL) to full-scale. Each simulant formulation was selected to be chemically representative of the waste streams anticipated to be fed to the LAWPS system, and used the current version of the LAWPS waste specification as a formulation basis. After simulant development iterations, four simulants of varying sodium concentration (5.6M, 6.0M, 4.0M, and 8.0M) were prepared and characterized. The formulation basis, development testing, and final simulant recipes and characterization data for these four simulants are presented in this report.

    Many hydrodynamic processes can be studied in a way that is scalable over a vastly relevant physical parameter space. We systematically examine this scalability, which has so far only briefly discussed in astrophysical literature. We show how the scalability is limited by various constraints imposed by physical processes and initial conditions. Using supernova remnants in different environments and evolutionary phases as application examples, we demonstrate the use of the scaling as a powerful tool to explore the interdependence among relevant parameters, based on a minimum set of simulations. In particular, we devise a scaling scheme that can be used to adaptively generate numerous seed remnants and plant them into 3D hydrodynamic simulations of the supernova-dominated interstellar medium.

    2008-08-01

    This paper reports the design and development of Digital Signal Controller (DSPIC)-based ECG simulator intended to use in testing, calibration and maintenance of electrocardiographic equipment, and to support biomedical engineering students' education. It generates all 12 healthy ECG derivation signals having a profile that varies with heart rate, amplitude, and different noise contamination in a manner which reflects true in vivo conditions. The heart rate can be set at the range of 30 to 120 beats/minute in four steps. The noise and power line interference effects can be set at the range of 0 to 20 dB in three steps. Since standard commercially available electronic components were used to construct the prototype simulator, the proposed design was also relatively inexpensive to produce.

    EXAFS is an important experimental technique for determining the local atomic structure of nanoclusters embedded in a bulk material. In practical cases, nanocluster samples do not contain homogeneous clusters of just one size, and the average cluster size is strongly influenced by the specific distribution of cluster sizes. Combinations of different cluster sizes might provide very similar results; this issue is called polydispersity. The goal of this study is to understand if there are any principal limitations for EXAFS studies related to polydispersity. Here a new approach based on EXAFS simulations followed by linear combination (LC) on EXAFS spectra is presented. The simulations were performed on pure Cu and binary Cu-Fe clusters. The main result of this study concerns the proof that polydispersity does not affect XAFS studies on nano-clusters within a size of up to 140 atoms.

    2014-01-01

    We investigate the effects of varying Saturn's orbit on the atmospheric circulation and surface methane distribution of Titan. Using a new general circulation model of Titan's atmosphere, we simulate its climate under four characteristic configurations of orbital parameters that correspond to snapshots over the past 42 kyr, capturing the amplitude range of long-period cyclic variations in eccentricity and longitude of perihelion. The model, which covers pressures from the surface to 0.5 mbar, reproduces the present-day temperature profile and tropospheric superrotation. In all four simulations, the atmosphere efficiently transports methane poleward, drying out the low- and mid-latitudes, indicating that these regions have been desert-like for at least tens of thousands of years. Though circulation patterns are not significantly different, the amount of surface methane that builds up over either pole strongly depends on the insolation distribution; in the present-day, methane builds up preferentially in the no...

  1. Electromagnetic Gyrokinetic Simulations

    2003-11-19

    A new electromagnetic kinetic electron {delta} particle simulation model has been demonstrated to work well at large values of plasma {beta} times the ion-to-electron mass ratio. The simulation is three-dimensional using toroidal flux-tube geometry and includes electron-ion collisions. The model shows accurate shear Alfven wave damping and microtearing physics. Zonal flows with kinetic electrons are found to be turbulent with the spectrum peaking at zero and having a width in the frequency range of the driving turbulence. This is in contrast with adiabatic electron cases where the zonal flows are near stationary, even though the linear behavior of the zonal flow is not significantly affected by kinetic electrons. zonal fields are found to be very weak, consistent with theoretical predictions for {beta} below the kinetic ballooning limit. Detailed spectral analysis of the turbulence data is presented in the various limits.

    2016-10-01

    An extended ensemble Monte Carlo algorithm is proposed by introducing a violation of the detailed balance condition to the update scheme of the inverse temperature in simulated tempering. Our method, irreversible simulated tempering, is constructed on the basis of the framework of the skew detailed balance condition. By applying this method to the ferromagnetic Ising model in two dimensions on a square lattice as a benchmark, the dynamical behavior of the inverse temperature and an autocorrelation function of the magnetization are studied numerically. It is found that the relaxation dynamics of the inverse temperature qualitatively change from diffusive to ballistic on violating the detailed balance condition. Consequently, the autocorrelation time of the magnetization is several times smaller than that for the conventional algorithm satisfying the detailed balance condition.

The CDG will provide multichannel, high performance 2D and 3D graphics, and real-time video manipulation. The architecture is designed for a compact implementation in the PAVE PILLAR environment using high-speed fiber optic networks. The CDG sustains the needs of the Panoramic Cockpit Control and Display System 2000 cockpit; it can be extensible to higher performance levels in PAVE PACE architectures.

    Science.gov (United States)

    About 150 million people worldwide are chronically infected with hepatitis C virus (HCV). The persistence of the infection is controlled by several mechanisms including the induction of oxidative stress. HCV relies on this strategy to redirect lipid metabolism machinery and escape immune response. The 3β-hydroxysterol Δ24-reductase (DHCR24) is one of the newly discovered host markers of oxidative stress. This protein, as HCV-induced oxidative stress responsive protein, may play a critical role in the pathogenesis of HCV chronic infection and associated liver diseases, when aberrantly expressed. The sustained expression of DHCR24 in response to HCV-induced oxidative stress results in suppression of nuclear p53 activity by blocking its acetylation and increasing its interaction with MDM2 in the cytoplasm leading to its degradation, which may induce hepatocarcinogenesis.

  17. This Battlefield Called My Body: Warring over the Muslim Female

    Directory of Open Access Journals (Sweden)

    Jameelah Medina

    2014-08-01

    Full Text Available This communication centers on the argument that there is an ideological tug-of-war over the Muslim female body. The author discusses how religious and secular patriarchies, as well as feminism all make claims to the bodies of Muslim women and purport to know what is best for her. With particular focus on the headscarf and using comparisons with how non-Muslim women’s bodies are fought over, the author argues that there is a common thread connecting the warring sides as they each employ patriarchal and imperialist views of the Muslim woman that attempt to consume her agency. As the author examines the personal agency and veiling motives of Muslim woman, she counters the idea of Muslim women as passive recipients of mainstream religious and secular narratives imposed upon them by sharing different ways in which they self-author their own narratives in a post-9/11 USA.

Rehabilitar a un preso terrorista es crucial para poner coto a la expansión del radicalismo. Una rehabilitación que implique corregir las erróneas concepciones religiosas de un terrorista, apoyándole/la psicológicamente y ofreciendo la reintegración en la sociedad es el complemento necesario a las medidas represivas. Sin embargo el desafío que presenta la diversidad de contextos en los que el Islam se encuentra, exige programas a medida dependiendo del lugar y del momento. Por ejemplo la reticencia en Occidente a contar con el apoyo de clérigos para luchar contra el radicalismo ideológico por el dogma de la separación entre el estado y la iglesia representa un obstáculo. Para llevarla a cabo seriamente, la rehabilitación ha de centrarse en los terroristas a nivel individual e implicar a la sociedad en cada nivel y con una multiplicidad de actores para frenar la expansión de la propaganda radical y así prevenir cualquier recaída. La evolución hacia un régimen global de programas de rehabilitación es el objetivo final de un acercamiento exitoso hacia la tarea de cambiar la mente de un terrorista.

    Proposed regulations targeting food marketing to children typically focus on traditional media, such as television, radio, and print ads. However, the widespread use of the Internet has promulgated novel food marketing strategies such as "advergaming," or the use of online games incorporating advertisements. In addition, the advent of so-called neuromarketing research is also allowing advertisers to appeal to the subconscious and emotional effects of food and beverage products, to which children may be particularly vulnerable. Current and future regulatory efforts should address the ubiquitous but often subtle marketing to which children are exposed and should measure success in terms of children's consumption of these products.

    1997-12-31

    A major part of technological advancement has involved the development of complex infrastructure systems, including electric power generation, transmission, and distribution networks; oil and gas pipeline systems; highway and rail networks; and telecommunication networks. Dependence on these infrastructure systems renders them attractive targets for conflict in the twenty-first century. Hostile governments, domestic and international terrorists, criminals, and mentally distressed individuals will inevitably find some part of the infrastructure an easy target for theft, for making political statements, for disruption of strategic activities, or for making a nuisance. The current situation regarding the vulnerability of the infrastructure can be summarized in three major points: (1) our dependence on technology has made our infrastructure more important and vital to our everyday lives, this in turn, makes us much more vulnerable to disruption in any infrastructure system; (2) technologies available for attacking infrastructure systems have changed substantially and have become much easier to obtain and use, easy accessibility to information on how to disrupt or destroy various infrastructure components means that almost anyone can be involved in this destructive process; (3) technologies for defending infrastructure systems and preventing damage have not kept pace with the capability for destroying such systems. A brief review of these points will illustrate the significance of infrastructure and the growing dangers to its various elements.

  1. Radiation in Particle Simulations

    Energy Technology Data Exchange (ETDEWEB)

    More, R; Graziani, F; Glosli, J; Surh, M

    2010-11-19

    Hot dense radiative (HDR) plasmas common to Inertial Confinement Fusion (ICF) and stellar interiors have high temperature (a few hundred eV to tens of keV), high density (tens to hundreds of g/cc) and high pressure (hundreds of megabars to thousands of gigabars). Typically, such plasmas undergo collisional, radiative, atomic and possibly thermonuclear processes. In order to describe HDR plasmas, computational physicists in ICF and astrophysics use atomic-scale microphysical models implemented in various simulation codes. Experimental validation of the models used to describe HDR plasmas are difficult to perform. Direct Numerical Simulation (DNS) of the many-body interactions of plasmas is a promising approach to model validation but, previous work either relies on the collisionless approximation or ignores radiation. We present four methods that attempt a new numerical simulation technique to address a currently unsolved problem: the extension of molecular dynamics to collisional plasmas including emission and absorption of radiation. The first method applies the Lienard-Weichert solution of Maxwell's equations for a classical particle whose motion is assumed to be known. The second method expands the electromagnetic field in normal modes (planewaves in a box with periodic boundary-conditions) and solves the equation for wave amplitudes coupled to the particle motion. The third method is a hybrid molecular dynamics/Monte Carlo (MD/MC) method which calculates radiation emitted or absorbed by electron-ion pairs during close collisions. The fourth method is a generalization of the third method to include small clusters of particles emitting radiation during close encounters: one electron simultaneously hitting two ions, two electrons simultaneously hitting one ion, etc. This approach is inspired by the virial expansion method of equilibrium statistical mechanics. Using a combination of these methods we believe it is possible to do atomic-scale particle

  2. Towards Quantum Simulating QCD

    2014-01-01

    Quantum link models provide an alternative non-perturbative formulation of Abelian and non-Abelian lattice gauge theories. They are ideally suited for quantum simulation, for example, using ultracold atoms in an optical lattice. This holds the promise to address currently unsolvable problems, such as the real-time and high-density dynamics of strongly interacting matter, first in toy-model gauge theories, and ultimately in QCD.

This is really a primer on the map-based "Courant Snyder" theory as independently proposed by Dragt's group (author included) and Turchetti's group at Bologna. Quite obviously it is viewed here from the author's own perspective and prejudices.

    Levy flights, also known as {alpha}-stable Levy processes or heavy-tailed statistics, are becoming a commonly used tool in optics. Nonetheless, the different parametrizations and the absence of any analytic expression for the distribution functions (apart from some exceptions) makes it difficult to efficiently simulate such processes. We review and compare three algorithms for the generation of sequences of symmetric stable Levy random variables.

    Electron slowing down and related phenomena are often greatly affected by bremsstrahlung production. Each creation of photon is individually simulated on the basis of a cross-section pack advised by Koch and Motz with corrections in the high energy frequency limit region. An accurate and fast sampling method is described. Its applicability covers a range between 50 keV and 80 MeV for target atoms whose atomic number is from 5 up to 90.

    Computational or scientific simulations are increasingly being applied to solve a variety of scientific problems. Domains such as astrophysics, engineering, chemistry, biology, and environmental studies are benefiting from this important capability. Simulations, however, produce enormous amounts of data that need to be analyzed and understood. In this overview paper, we describe scientific simulation data, its characteristics, and the way scientists generate and use the data. We then compare and contrast simulation data to data streams. Finally, we describe our approach to analyzing simulation data, present the AQSim (Ad-hoc Queries for Simulation data) system, and discuss some of the challenges that result from handling this kind of data.

    Soares, Cláudio M; Baptista, António M

    2012-03-09

    This article presents an overview of the simulation studies of the behaviour of multihaem cytochromes using theoretical/computational methodologies, with an emphasis on cytochrome c(3). It starts with the first studies using rigid molecules and continuum electrostatic models, where protonation and redox events were treated as independent. The gradual addition of physical details is then described, from the inclusion of proton isomerism, to the proper treatment of the thermodynamics of electron-proton coupling, to the explicit inclusion of the solvent and protein structural reorganization into the models, culminating with the method for molecular dynamics simulations at constant pH and reduction potential, where the solvation, conformational, protonation and redox features are all simulated in a fully integrated and coupled way. We end with a discussion of the strategies used to study the interaction between multihaem cytochromes, taking into account the further coupling effect introduced by the molecular association.

    This paper details the new thermal-hydraulics and shutdown margin calculation modules of Studsvik Scandpower's next generation nodal code, SIMULATE-4. SIMULATE-4's BWR thermal-hydraulics (TH) models an entire vessel loop: core, chimney (for natural circulation reactors), upper plenum, standpipes, steam separators, down comer, re-circulation pumps, and lower plenum. The PWR thermal-hydraulics models the region from lower to upper tie plate. The core portion of the TH models of PWR and BWRs are treated essentially identically, with each assembly having an active channel and a number of parallel water channels. In each axial node of a channel, the total mixture mass, steam mass, mixture enthalpy, and mixture momentum balance equations are solved. The 3-D fuel temperatures are evaluated in the TH module by solving the radial heat conduction equation for the average pin of each node. The BWR assembly may be divided into four radial sub-channels. Assembly or nodal cross flow is allowed for PWRs. A new three-dimensional shutdown margin (SDM) method based on 'mini-core' concept has been developed in SIMULATE-4. 'Mini-core' geometry is used as a fast screening tool where full 3D calculations are performed for those rods identified with SDM smaller than the user's input criteria. Various numerical test results are presented to illustrate improvements with each module. (authors)

    cathode, made using an AIGaAs heterostructure step. Simulations show the importance of the insertion of a thin highly-doped layer between the transit region and the electron launcher in order to improve device operation. Chapter 5 is an introduction to Ill-nitrides, in particular GaN and its alloy ln-GaN. We outline the discrepancy in the elastic and piezoelectric parameters found in the literature. Strain, dislocations and piezoelectricity are presented as the main features of a InGaN/GaN system. In chapter 6 an extensive simulation of the dependence of the optical band gap of a single InGaN quantum well on the piezoelectric and spontaneous polarization is reported. Quantum Confined Stark Effect and screening mechanisms are found to play a major role. The simulation of a novel InGaN/GaN double quantum well LED is presented. A wide well is used to capture electrons that tunnels in a narrow well where they recombine with holes. Resonant asymmetric tunneling of electron and holes is used to increase the efficie...

  14. Exploration Supply Chain Simulation

    The Exploration Supply Chain Simulation project was chartered by the NASA Exploration Systems Mission Directorate to develop a software tool, with proper data, to quantitatively analyze supply chains for future program planning. This tool is a discrete-event simulation that uses the basic supply chain concepts of planning, sourcing, making, delivering, and returning. This supply chain perspective is combined with other discrete or continuous simulation factors. Discrete resource events (such as launch or delivery reviews) are represented as organizational functional units. Continuous resources (such as civil service or contractor program functions) are defined as enabling functional units. Concepts of fixed and variable costs are included in the model to allow the discrete events to interact with cost calculations. The definition file is intrinsic to the model, but a blank start can be initiated at any time. The current definition file is an Orion Ares I crew launch vehicle. Parameters stretch from Kennedy Space Center across and into other program entities (Michaud Assembly Facility, Aliant Techsystems, Stennis Space Center, Johnson Space Center, etc.) though these will only gain detail as the file continues to evolve. The Orion Ares I file definition in the tool continues to evolve, and analysis from this tool is expected in 2008. This is the first application of such business-driven modeling to a NASA/government-- aerospace contractor endeavor.

    Despite the popularity of the Apache Hadoop system, its success has been limited by issues such as single points of failure, centralized job/task management, and lack of support for programming models other than MapReduce. The next generation of Hadoop, Apache Hadoop YARN, is designed to address these issues. In this paper, we propose YARNsim, a simulation system for Hadoop YARN. YARNsim is based on parallel discrete event simulation and provides protocol-level accuracy in simulating key components of YARN. YARNsim provides a virtual platform on which system architects can evaluate the design and implementation of Hadoop YARN systems. Also, application developers can tune job performance and understand the tradeoffs between different configurations, and Hadoop YARN system vendors can evaluate system efficiency under limited budgets. To demonstrate the validity of YARNsim, we use it to model two real systems and compare the experimental results from YARNsim and the real systems. The experiments include standard Hadoop benchmarks, synthetic workloads, and a bioinformatics application. The results show that the error rate is within 10% for the majority of test cases. The experiments prove that YARNsim can provide what-if analysis for system designers in a timely manner and at minimal cost compared with testing and evaluating on a real system.

    Radio observations of galaxy clusters show that the intracluster medium is permeated by ? magnetic fields. The origin and evolution of these cosmological magnetic fields is currently not well understood, and so their impact on the dynamics of structure formation is not known. Numerical simulations are required to gain a greater understanding and produce predictions for the next generation of radio telescopes. We present the galactic chemodynamics smoothed particle magnetohydrodynamics (SPMHD) code (GCMHD+), which is an MHD implementation for the cosmological smoothed particle hydrodynamics code GCD+. The results of 1D, 2D and 3D tests are presented and the performance of the code is shown relative to the ATHENA grid code. GCMHD+ shows good agreement with the reference solutions produced by ATHENA. The code is then used to simulate the formation of a galaxy cluster with a simple primordial magnetic field embedded in the gas. A homogeneous seed field of 3.5 × 10-11 G is amplified by a factor of 103 during the formation of the cluster. The results show good agreement with the profiles found in other magnetic cluster simulations of similar resolution.

    Full Text Available Desiccant cooling system has been an attractive topic for study lately, due to its environmentally friendly nature. It also consume less electricity and capable to be operated without refrigerant. A simulation study was conducted using 1.5 m long ducting equipped with one desiccant wheel, one sensible heat exchanger wheel, one evaporative cooling chamber and two blowers and one electric heater. The simulation study used 8.16 m/s primary air, the drying coefficient from desiccant wheel, k1=2.1 (1/s, mass transfer coefficient in evaporative cooling, k2=1.2 kg vapor/s, heat transfer coefficient in desiccant wheel, h1=4.5 W/m2 oC, and heat transfer coefficient in sensible heat exchanger wheel h2= 4.5 W/m2 oC. The simulation results show that the final temperature before entering into the air conditioning room was 25 oC and RH of 65 %, were in accordance with the Indonesian comfort index.

    Full Text Available Abstract Background The amount of genome-wide molecular data is increasing rapidly, as is interest in developing methods appropriate for such data. There is a consequent increasing need for methods that are able to efficiently simulate such data. In this paper we implement the sequentially Markovian coalescent algorithm described by McVean and Cardin and present a further modification to that algorithm which slightly improves the closeness of the approximation to the full coalescent model. The algorithm ignores a class of recombination events known to affect the behavior of the genealogy of the sample, but which do not appear to affect the behavior of generated samples to any substantial degree. Results We show that our software is able to simulate large chromosomal regions, such as those appropriate in a consideration of genome-wide data, in a way that is several orders of magnitude faster than existing coalescent algorithms. Conclusion This algorithm provides a useful resource for those needing to simulate large quantities of data for chromosomal-length regions using an approach that is much more efficient than traditional coalescent models.
