  2. Biological effects of embedded depleted uranium (DU). Summary of Armed Forces Radiobiology Research Institute research

    International Nuclear Information System (INIS)

    The Persian Gulf War resulted in injuries of US Coalition personnel by fragments of depleted uranium (DU). Fragments not immediately threatening the health of the individuals were allowed to remain in place, based on long-standing treatment protocols designed for other kinds of metal shrapnel injuries. However, questions were soon raised as to whether this approach is appropriate for a metal with the unique radiological and toxicological properties of DU. The Armed Forces Radiobiology Research Institute (AFRRI) is investigating health effects of embedded fragments of DU to determine whether current surgical fragment removal policies remain appropriate for this metal. These studies employ rodents implanted with DU pellets as well as cultured human cells exposed to DU compounds. Results indicate uranium from implanted DU fragments distributed to tissues far-removed from implantation sites, including bone, kidney, muscle, and liver. Despite levels of uranium in the kidney that were nephrotoxic after acute exposure, no histological or functional kidney toxicity was observed. However, results suggest the need for further studies of long-term health impact, since DU was found to be mutagenic, and it transformed human osteoblast cells to a tumorigenic phenotype. It also altered neurophysiological parameters in rat hippocampus, crossed the placental barrier, and entered fetal tissue. This report summarizes AFRRI's depleted uranium research to date

  3. Emergency Surgery after Failed Percutaneous Transmitral Commissurotomy (PTMC) at Armed Forces Institute of Cardiology (AFIC)

    International Nuclear Information System (INIS)

    Objective: The aim of this study was to analyze the outcome of emergency after PTMC. Design: A cross-sectional study. Place and Duration of Study: Armed Forces Institute of Cardiology (AFIC) Rawalpindi from January 2005 to June 2009. Patients and Methods: A cross-sectional study of 12 patients (2.3 percent) out of 523 who underwent PTMC and developed significant mitral regurgitation (MR) or cardiac tamponade (CT) was examined to analyze the outcome of emergency surgery. Transthoracic echocardiography (TTE) was used to select patients of MS with minimal calcification and transesophageal echocardiography (TEE) was used to rule out left atrial (LA) clot. Inuoe balloon was used in all cases for PTMC. Results: Out of twelve who presented for surgery after failed PTMC, 9(75 percent) had significant MR and 3(25 percent) had CT. Majority of patients were female (83.3 percent) with mean age of 30.9+-5.12 years. In patients with MR, anterior mitral leaflet (AML) tear was found in 8(66.7 percent) and posterior mitral leaflet tear in 1(8.3 percent). LA clot was found in 1(8.3 percent) patient who caused cerebral infarction. All patients underwent mitral valve replacement (MVR) with prosthetic valve on cardiopulmonary bypass (CPB). Two patients (16.7 percent) died; one because of cerebral infarction and one due to low cardiac output syndrome (LCOS). Conclusion: With increasing experience of PTMC the magnitude of failure cases is decreasing as was seen in our case in which failed percentage was just 2.3 percent. Moreover, percentage of success of emergency surgery was good i.e. 83.3 percent. In case of failure a well coordinated effort between cardiologist and surgical team can prevent mortality significantly. (author)

  13. Optimizing Armed Forces Capabilities for Hybrid Warfare – New Challenge for Slovak Armed Forces

    Directory of Open Access Journals (Sweden)

    Peter PINDJÁK

    2015-09-01

    Full Text Available The paper deals with the optimization of military capabilities of the Slovak Armed Forces for conducting operations in a hybrid conflict, which represents one of the possible scenarios of irregular warfare. Whereas in the regular warfare adversaries intend to eliminate the centers of gravity of each other, most often command and control structures, in irregular conflicts, the center of gravity shifts towards the will and cognitive perception of the target population. Hybrid warfare comprises a thoroughly planned combination of conventional military approaches and kinetic operations with subversive, irregular activities, including information and cyber operations. These efforts are often accompanied by intensified activities of intelligence services, special operation forces, and even mercenary and other paramilitary groups. The development of irregular warfare capabilities within the Slovak Armed Forces will require a progressive transformation process that may turn the armed forces into a modern and adaptable element of power, capable of deployment in national and international crisis management operations.

Many countries have designed their armies in accordance with these studies. The Turkish Armed Forces (TAF believes the importance of these studies and designs education systems and training in the selection and training of the leaders. The biggest advance in the TAF was being held during the period of education and training improvement. This study investigates to bring that issue into focus and offers a whole social science agenda for leadership in the TAF related research. In this article exploratory research was applied and military history specimens were used. The results of the study demonstrate the geographically powerful armed forces are always needed. A powerful army can indicate the presence of strong leadership. The criteria determined by the selection and training of staff will be one of the most essential tasks that will lead the TAF into the future. These results, however, need further work to validate reliability.

    Full Text Available The basic aim of the research was to discover the meaning of sport, its value among the soldiers and officers and its motivational effect and the correlation between sport in the army and general health and satisfaction with work and life. We tried to research the positive effects of sport on the work efficiency in Slovenian Armed Forces. Different sport psychological measurements and tests have been in research. We used Self-motivation Inventory, Participation (in sport Motivation Inventory, Work Motivation, General Health Questionnaire, Attitudes Toward Sport, Work Efficency Scale, Satisfaction with Life Scale and Body Mass Index. 141 subjecs were involved into the researh (75 sodiers and 66 officers in Slovenian Armed Forces. The results showed many useful data. There is a positive connection between attitudes toward sport and general health and satisfaction in work. There is also a positive connection between sport attitudes and work efficiency. The main sport motives for the employers in Slovenian Armed Forces are: they like friendship and brotherhood through sport, they want to stay fit and they want to learn new sport skills. Through these results we can confirm very positive effects of sport on the general life and work in the Army. New researches should follow to discover more directions for practical suggestions.

    2010-12-01

    This study analyzed the relationship between mechanical force production and spatial arm position of the swimming movement for each side of the swimmer. Eight internationally recognized male swimmers performed fix positioned arm only swimming with a dynamometer synchronized with underwater cameras. The upper arm positions (α in side, β in frontal view) and the elbow angles (γ in 3D) were determined at the moment where the force production reached the peak (Fmax) and the maximal values of rate of force development (RFDmax). RFDmax and α values showed significant differences between the sides (P<0.05). To show the motion integration structure of the performance, Multiple Regression Analysis (MRA) was employed separately for both sides. For the criterion variable, the impulse of force (ImpF50%) was calculated. The defined parameters as the mechanical and spatial predictor system were used for the model. The results of the MRA showed that the predictor system yielded the model structure of the variables that explain the criterion variables for ImpF50% by the dominant (P=0.007) and by the nondominant side (P=0.001), respectively. The alternate contribution of the variables to the models can objectively express the performance difference between the two sides of the swimmer. PMID:21138814

    1. Forward reaching movements made during body rotation generate tangential Coriolis forces that are proportional to the cross product of the angular velocity of rotation and the linear velocity of the arm. Coriolis forces are inertial forces that do not involve mechanical contact. Virtually no constant centrifugal forces will be present in the background when motion of the arm generates transient Coriolis forces if the radius of body rotation is small. 2. We measured the trajectories of arm movements made in darkness to a visual target that was extinguished as movement began. The reaching movements were made prerotation, during rotation at 10 rpm in a fully enclosed rotating room, and postrotation. During testing the subject was seated at the center of the room and pointed radially. Neither visual nor tactile feedback about movement accuracy was present. 3. In experiment 1, subjects reached at a fast or slow rate and their hands made contact with a horizontal surface at the end of the reach. Their initial perrotary movements were highly significantly deviated relative to prerotation in both trajectories and end-points in the direction of the transient Coriolis forces that had been generated during the reaches. Despite the absence of visual and tactile feedback about reaching accuracy, all subjects rapidly regained straight movement trajectories and accurate endpoints. Postrotation, transient errors of opposite sign were present for both trajectories and endpoints. 4. In a second experiment the conditions were identical except that subjects pointed just above the location of the extinguished target so that no surface contact was involved. All subjects showed significant initial perrotation deviations of trajectories and endpoints in the direction of the transient Coriolis forces. With repeated reaches the trajectories, as viewed from above, again became straight, but there was only partial restoration of endpoint accuracy, so that subjects reached in a straight

    The ability to predict the musculoskeletal response to external loads has multiple applications for the design of machines with a human interface and for the prediction of outcomes of musculoskeletal interventions. In this study, we applied an inverse-inverse dynamics technique to investigate its ability to predict arm posture in response to isometric hand forces. For each subject, we made a three-dimensional musculoskeletal model using the AnyBody Modelling System (AMS). Then, we had each subject-specific model hold a weight anteriorly to the right shoulder joint at a distance of half of the arm length. We selected the glenohumeral abduction angle (GHAA) as the only free parameter. Subsequently, we used inverse-inverse dynamics to find the optimal GHAA that minimised a performance criterion with physiological constraints. In this study, we investigated the performance of two different objective functions: summation of squared muscle activity (SSMA) and summation of squared normalised joint torques (SSNJT). To validate the simulation results, arm posture responses to different isometric downward hand forces were measured for six healthy male subjects. Five trials were performed for each loading condition. The results showed that, with an increase in hand load, there was a reduced GHAA in all subjects. Another interesting finding was that self-selected postures for lighter tasks varied more than postures for heavier tasks for all subjects. To understand this, we investigated the curvature of the objective function as a function of the load and observed an increased curvature with increased load. This may explain the reduced intra-subject variations observed for increasing loads. PMID:26482735

  11. Conventional armed forces in Europe: Technology scenario development

    Houser, G.M.

    1990-07-01

    In January 1986, the Soviet Union's Mikhail Gorbachev proposed elimination of all nuclear weapons by the year 2000. In April of that year, Mr. Gorbachev proposed substantial reductions of conventional weapons in Europe, from the Atlantic Ocean to the Ural Mountains, including reductions in operational-tactical nuclear weapons. In May 1986, the North Atlantic Treaty Organization (NATO) responded with the Brussels Declaration on Conventional Arms Control,'' which indicated readiness to open East/West discussions on establishing a mandate for negotiating conventional arms control throughout Europe. The Group of 23,'' which met in Vienna beginning in February 1987, concluded the meeting in January 1989 with a mandate for the Conventional Armed Forced in Europe (CFE) negotiations. On 6 March 1989, CFE talks began, and these talks have continued through six rounds (as of April 1990). Although US President George Bush, on 30 May 1989, called for agreement within six months to a year, and the Malta meeting of December 1989 called for completion of a CFE agreement by the end of 1990, much remains to be negotiated. This report provides three types of information. First, treaty provisions brought to the table by both sides are compared. Second, on the basis of these provisions, problem areas for each of the provision elements are postulated and possible scenarios for resolving these problem areas are developed. Third, the scenarios are used as requirements for tasks assigned program elements for possible US implementation of a CFE treaty. As progress is achieved during the negotiations, this report could be updated, as necessary, in each of the areas to provide a continuing systematic basis for program implementation and technology development. 8 refs.

  12. DRUG USE ATTITUDE OF TURKISH ARMED FORCES PILOTS

    Full Text Available Introduction: Because of the dangers in the nature of flight, pilots have to fly in perfect medical conditions. Besides the undesirable effects of the diseases, side effects of the medications used in the treatment might also risk flight safety. In this study, we investigated the drug use attitude of Turkish Armed Forces pilots. Material-Method: In order to investigate their drug use attitude, a questionnaire was given to 408 pilots at GATA Aerospace Medical Center. Drug use attitude, drugs used by pilots and side effects were questioned. Results: 41 % of pilots reported that they used drugs during active flying. But the drug use rate of Army pilots was 57 %, which was higher than the Air Force and Navy pilots. The most common used drugs were analgesics. Conclusion: It is obvious that pilots might use drugs without informing their flight surgeon. Flight surgeons should always educate the pilots about the importance and dangers of self-medication.

    In the article the problems concerning characteristic features of the local wars and armed conflicts, organization bases of construction of The Army and Fleet medical support modern system are discussed. The organization of personnel medical security is considered depending on the duration, intensity and spatial scope of military conflict, peculiarities of group (forces) application and ways of military actions conduction. The distribution of federal troops sanitary losses during the war in Chechenskaya Republic is shown depending on the type, localization and degree of injuries gravity as well as volume of the wounded and invalids evacuation by air transport and work of military medical institutions. The following principles of construction of the Armed Forces medical support system are formulated: The system must be in compliance with troops goals, structure, strategy and tactics, its specificity; development of medical security forms and methods, their historicism; interdependency, completeness and integrity of the system's elements; territorial aspects of its construction and management optimization. Considering character of the goals being laid on the Mobile Forces the paramount importance is attached to the level of readiness of medical service and its formations and units to act in crisis situations.

By using the concept of Hegemonic Masculinity, sexual harassment of the women in the Swedish Armed Forces is explained in terms of a need of the men within the organisation to reinforce the notion of women as inferior and subordinate to men, whereby the external hegemony is believed to be restored. Likewise, male Swedish peacekeepers’ demand for prostitutio...

    Most nations spend a considerable part of their gross domestic product (GDP) on defense. However, no previous study has addressed the productivity and efficiency of the core area of the armed forces, operational units, using Data Envelopment Analysis (DEA). Introducing a model for the production process of an operational unit, productivity and efficiency are estimated by DEA for units of one branch of the Norwegian armed forces. Small samples are a characteristic of DEA studies in the militar...

  18. Optimal arm posture control and tendon traction forces of a coupled tendon-driven manipulator

    International Nuclear Information System (INIS)

    In this study, the optimum arm posture of a coupled tendon-driven multijoint manipulator arm (or CT Arm) at maximum payload output was derived and the corresponding tendon traction forces were also analyzed, during management of a heavy payload by the manipulator in a gravity environment. The CT Arm is special tendon traction transmission mechanism in which a pair of tendons used to drive a joint is pulled from base actuators via pulleys mounted on the base-side joints. This mechanism enables optimal utilization of the coupled drive function of tendon traction forces and thus enables the lightweight manipulator to exhibit large payload capability. The properties of the CT Arm mechanism are elucidated by the proposed optimal posture control scheme. Computer simulation was also executed to verify the validity of the proposed control scheme.

    In three experiments, the effect of water mist spray on self-injurious and collateral behaviors was compared with either facial screening or forced arm exercise. Water mist spray was as effective as facial screening in suppressing face-slapping in Experiment 1. However, it was not as effective as facial screening for self-injurious finger-licking in Experiment 2 or forced arm exercise for excessive ear-rubbing in Experiment 3. These results suggest that while water mist spray is effective, it...

It argues that the higher military leadership in Bishkek shares a common distrust of the Tashkent regime and overall uncertainly about power sharing two months after regime change, while lower level personnel may have provoked the Uzbek minority, because of their nationalist feelings (the majority of police and army personnel are ethnic Kyrgyz and overall frustration with the fragmented political leadership. The situation was further exacerbated by the lack of political control over the security forces and their lack of adequate training to deal with civic unrest.

  16. Rehabilitation of a Human Arm Supported by a Robotic Manipulator: A Position/Force Cooperative Control

    Directory of Open Access Journals (Sweden)

    Haifa Mehdi

    2010-01-01

    Full Text Available Problem statement: The assistance of person with limited ability of arm movement is necessary for rehabilitation reasons. This aid is required not only to cover the human performances of the arm in motion and force but also to have a strictly stable dynamics. In this study, we proposed a cooperative system between a disabled arm and a robotic manipulator to reach such objectives. Desired positions and contact forces were imposed by the disabled human whereas appropriate torques were applied by the manipulator to follow human intension. Approach: Various control strategies were proposed during recent years to solve position/force control problem. The impedance control concept was used in this study. A relationship between the dynamics of the robot and its energy was developed to derive stability conditions of the robotic system at the constrained motion phase using a suitable Lyapunov approach. Results: New sufficient conditions of asymptotic stability were developed. To prove the efficiency of the proposed approach, a prototype of a human arm coupled to cooperative constrained robotic manipulator was used. The simulation results showed the stability and the performances of the proposed approach. Conclusion: Results showed the possibility of their use in a real context of rehabilitation of injured and disabled people.

    Full Text Available The authors propose a comparison between two force-position controllers with gravity compensation simulated on the DEXTER bioinspired robotic arm. The two controllers are both constituted by an internal proportional-derivative (PD closed-loop for the position control. The force control of the two systems is composed of an external proportional (P closed-loop for one system (P system and an external proportional-integrative (PI closed-loop for the other system (PI system. The simulation tests performed with the two systems on a planar representation of the DEXTER, an eight-DOF bioinspired arm, showed that by varying the stiffness of the environment, with a correct setting of parameters, both systems ensure the achievement of the desired force regime and with great precision the desired position. The two controllers do not have large differences in performance when interacting with a lower stiffness environment. In case of an environment with greater rigidity, the PI system is more stable. The subsequent implementation of these control systems on the DEXTER robotic bioinspired arm gives guidance on the design and control optimisation of the arms of the humanoid robot named SABIAN.

    Full Text Available The paper considers a problem pertaining to reduction of the Armed Forces of the Republic of Belarus and necessity to carry out economically reasonable reforms optimizing strength of financial personnel with the purpose to decrease its number but without undermining financial and operational activities of the Armed Forces as a whole. It has been proposed to optimize strength of financial personnel in the Armed Forces while executing organizational staff transformations such as introduction of a centralized accounting system for service personnel by an example of the Ministry of Defense of the Russian Federation.Normative for financial personnel strength of the supposed unified financial centre which is involved in accounting recordings on salary and other payments has been calculated on the basis of inter-branch standards. While taking as an example a conventional organization “B” with staff strength which is equal to the strength of the Armed Forces of the Republic of Belarus the possible efficiency in introduction of the centralized accounting system for service personnel has been determined in the paper. According to represented calculations reduction of financial personnel dealing with accounting recordings on salary and other payments in the whole organization “B” can constitute up to 60 persons with more than 200 branches which are carrying out independent payment accounting for personnel concerned.Dependence of strength normative on number of financial bodies, percentage of personnel receiving payments through a unified financial centre and concentration of financial and economic document circulation has been determined in the paper. It has been pointed out that it is not sufficient to determine quantitative indices in order to ensure an objective reflection of the efficiency of possible introduction of the centralized accounting system for service personnel in the Armed Forces.

  8. Hereditary cerebellar ataxia progressively impairs force adaptation during goal-directed arm movements.

    Science.gov (United States)

    Maschke, Matthias; Gomez, Christopher M; Ebner, Timothy J; Konczak, Jürgen

    2004-01-01

    We investigated how humans with hereditary cerebellar degeneration [spinocerebellar ataxia (SCA) type 6 and 8, n = 9] and age- and sex-matched healthy controls (n = 9) adapted goal-directed arm movements to an unknown external force field. We tested whether learning could be generalized to untrained regions in the workspace, an aspect central to the idea of an internal model, and if any learning could be retained. After removal of the force field, SCA patients showed little or no learning-related aftereffects indicating that repeated force-field exposure never led to successful force compensation. In contrast, healthy control subjects quickly adapted their movements to the new force field. The difference in force adaptation was significant for movements to targets that required both the shoulder and elbow joint (P < 0.001). Moreover, the generalization of learned movements to targets outside the learned workspace was prevented by the cerebellar degeneration (P < 0.01). Retention of force adaptation was significantly lower in SCA patients (P = 0.003). The severity of ataxia in SCA patients correlated negatively with the extent of learning (r = -0.84, P = 0.004). Our findings imply that progressive loss of cerebellar function gradually impairs force adaptation. The failure to generalize learning suggests that cerebellar degeneration prevents the formation of an internal representation of the limb dynamics. PMID:13679403

    Xu, Y; Terekhov, AV; Latash, ML; Zatsiorsky, VM

    2012-01-01

    This is an exploratory study of the accurate endpoint force vector production by the human arm in isometric conditions. We formulated three common-sense hypotheses and falsified them in the experiment. The subjects (n=10) exerted static forces on the handle in eight directions in a horizontal plane for 25 seconds. The forces were of 4 magnitude levels (10 %, 20%, 30% and 40% of individual MVC). The torsion moment on the handle (grasp moment) was not specified in the instruction. The two force components and the grasp moment were recorded, and the shoulder, elbow, and wrist joint torques were computed. The following main facts were observed: (a) While the grasp moment was not prescribed by the instruction, it was always produced. The moment magnitude and direction depended on the instructed force magnitude and direction. (b) The within-trial angular variability of the exerted force vector (angular precision) did not depend on the target force magnitude (a small negative correlation was observed). (c) Across the target force directions, the variability of the exerted force magnitude and directional variability exhibited opposite trends: In the directions where the variability of force magnitude was maximal, the directional variability was minimal and vice versa. (d) The time profiles of joint torques in the trials were always positively correlated, even for the force directions where flexion torque was produced at one joint and extension torque was produced at the other joint. (e) The correlations between the grasp moment and the wrist torque were negative across the tasks and positive within the individual trials. (f) In static serial kinematic chains, the pattern of the joint torques distribution could not be explained by an optimization cost function additive with respect to the torques. Plans for several future experiments have been suggested. PMID:23080084

    Full Text Available 2012 has a double significance for this year sees the centenary of the founding of the African National Congress (8 January and of the creation of the Union Defence Forces (1 July, two organisations that have for much of the twentieth century shared a contested history. Yet, in a remarkable bouleversement, South Africa has come through this difficult past and, over the past two decades, a new South African society has been recreated following an interesting period of adjustment following the end of the Cold War and the growth of democracy in the developing world. These changes have necessarily affected her armed forces and the roles defined for them. Some commentators, particularly in the years immediately following 1994, asserted that military power had lost all of its vaunted, Cold-War importance in a new postmodern environment. Others still, recognising future challenges, argued that South Africa, beset with far-reaching socio-economic crises, could no longer afford the burden of military forces. Most scholars agree now that these perspectives were short-sighted and that, while the risk of major conflict has receded, the events of 9/11, and its consequences, demonstrate that the continental and international landscapes are less certain, less stable and less predictable, than that for which many had hoped. Clearly, South African interests are intertwined inextricably in regional and global affairs and if she is to protect these interests and ensure her security, she must maintain credible military force capable of meeting an array of contingencies. It was with this in mind that the strategic arms deal, since the subject of much debate, was passed by parliament:[i] the promise of a full technological transformation, to accompany the human transformation, offered.

    1. Reaching movements made in a rotating room generate Coriolis forces that are directly proportional to the cross product of the room's angular velocity and the arm's linear velocity. Such Coriolis forces are inertial forces not involving mechanical contact with the arm. 2. We measured the trajectories of arm movements made in darkness to a visual target that was extinguished at the onset of each reach. Prerotation subjects pointed with both the right and left arms in alternating sets of eight movements. During rotation at 10 rpm, the subjects reached only with the right arm. Postrotation, the subjects pointed with the left and right arms, starting with the left, in alternating sets of eight movements. 3. The initial perrotary reaching movements of the right arm were highly deviated both in movement path and endpoint relative to the prerotation reaches of the right arm. With additional movements, subjects rapidly regained straight movement paths and accurate endpoints despite the absence of visual or tactile feedback about reaching accuracy. The initial postrotation reaches of the left arm followed straight paths to the wrong endpoint. The initial postrotation reaches of the right arm had paths with mirror image curvature to the initial perrotation reaches of the right arm but went to the correct endpoint. 4. These observations are inconsistent with current equilibrium point models of movement control. Such theories predict accurate reaches under our experimental conditions. Our observations further show independent implementation of movement and posture, as evidenced by transfer of endpoint adaptation to the nonexposed arm without transfer of path adaptation. Endpoint control may occur at a relatively central stage that represents general constraints such as gravitoinertial force background or egocentric direction relative to both arms, and control of path may occur at a more peripheral stage that represents moments of inertia and muscle dynamics unique to each

    2015-06-01

    Full Text Available This paper describes the design, development and evaluation tests of an integrated force sensor prototype for portable Coordinate Measuring Arms (CMAs or AACMMs. The development is based on the use of strain gauges located on the surface of the CMAs’ hard probe. The strain gauges as well as their cables and connectors have been protected with a custom case, made by Additive Manufacturing techniques (Polyjet 3D. The same method has been selected to manufacture an ergonomic handle that includes trigger mechanics and the electronic components required for synchronizing the trigger signal when probing occurs. The paper also describes the monitoring software that reads the signals in real time, the calibration procedure of the prototype and the validation tests oriented towards increasing knowledge of the forces employed in manual probing. Several experiments read and record the force in real time comparing different ways of probing (discontinuous and continuous contact and measuring different types of geometric features, from single planes to exterior cylinders, cones, or spheres, through interior features. The probing force is separated into two components allowing the influence of these strategies in probe deformation to be known. The final goal of this research is to improve the probing technique, for example by using an operator training programme, allowing extra-force peaks and bad contacts to be minimized or just to avoid bad measurements.

    A particular emphasis is put on a novel wearable exoskeleton arm, ZJUESA, with 6 degrees of freedom, which is used for the robot teleoperation with the force-feedback in the unknown environment. In this external structure mechanism, the 3-revolution-prismatic-spherical (3RPS) parallel mechanism is devised from the concept of the human upper-limb anatomy and applied for the shoulder 3-DOF joint. Meanwhile, the orthogonal experiment design method is introduced for its optimal design. Aiming at enhancing the performance of teleoperation, the force feedback is employed by the pneumatic system on ZJUESA to produce the vivid feeling in addition to the soft control interface. Due to the compressibility and nonlinearity of the pneumatic force feedback system, a novel hybrid fuzzy controller for the precise force control is proposed and realized based on the Mega8 microcontroller units as the units of the distributed control system on ZJUESA. With the results of several experiments for master-slave control with force feedback, the feasibility of ZJUESA system and the effect of its hybrid fuzzy controller are verified.

    2014-01-01

    We present a detailed study of of a global bifurcation occuring in a turbulent von K\\'arm\\'an swirling flow. In this system, the statistically steady states progressively display hysteretic behaviour when the Reynolds number is increased above the transition to turbulence. We examine in detail this hysteresis using asymmetric forcing conditions --- rotating the impellers at different speeds. For very high Reynolds numbers, we study the sensitivity of the hysteresis cycle --- using complementary Particle Image Velocimetry (PIV) and global mechanical measurements --- to the forcing nature, imposing either the torque or the speed of the impellers. New mean states, displaying multiple quasi-steady states and negative differential responses, are experimentally observed in torque control. A simple analogy with electrical circuits is performed to understand the link between multi-stability and negative responses. The system is compared to other, similar "bulk" systems, to understand some relevant ingredients of nega...

  19. Etiology and pattern of maxillofacial injuries in the armed forces of pakistan

    International Nuclear Information System (INIS)

    To determine the etiology and pattern of maxillofacial injuries in the Armed Forces of Pakistan in terms of anatomical distribution of injuries. Three hundred consecutive patients of Armed Forces of Pakistan with maxillofacial injuries reporting to AFID and admitted to the hospital or treated as out-patients in the oral surgery clinic, were included in this study. Isolated nasal bone and frontal sinus fractures were excluded from the study. Anatomical distribution, frequency and etiology of fractures, rank at job and occupational as well as personal hobbies were recorded. Descriptive analyses were used to determine mean, standard deviation, percentage and range values. The most frequent bone fractured was the mandible, which accounted for 159 cases (53%). The zygomatic complex was fractured in 51 cases (17%), the maxilla in 12 cases (4 %), and the alveolar process in 21 cases (7%). The most common cause was road traffic accident (168 cases; 56%), followed by accidental fall (69 cases; 23%), gunshot injuries (27 cases; 9%), sports related injuries (15 cases; 5%), and injury associated with a fight (12 cases; 4%); there were only 9 cases of animals related injuries (3%). In this series, mandible was the most commonly fractured facial bone, while road traffic accident was the most common etiological factor. Results could be influenced by the personal and working environment. (author)

Its content is represented by general principles, communication and counseling, creating links, risk assessment, monitoring and review of risks, handling and record of the process of risk management. In terms of The Armed Forces of the SR (OS SR, this issue is an important part of management in terms of proper functionality of the components, services, and facilities (qualifications. It is certainly the difficulty and danger incurred by the processes carried out in these organizational structures (e.g. shooting, weapon handling and training, etc. that provides a clear answer on what is necessary to do for a successful implementation of risk management issues.

  2. A comparative study of the active force control schemes applied to robot arm

    International Nuclear Information System (INIS)

    In this paper, a comparative study of three different types of active force control (AFC) schemes applied to a robotic arm is described. The study particularly focuses on the techniques to compute the estimated inertia matrix (ΙΝ) of a robotic manipulator necessary for the execution of the AFC strategy since the computation of (ΙΝ) is the common central theme to all AFC-based schemes. The first of the three AFC schemes is based on the conventional method of obtaining (ΙΝ), the second uses artificial neural network while the third incorporates an iterative learning algorithm. The study also discusses the characteristics of the (ΙΝ) curves obtained, the trajectory track performance of the schemes and the effects of the modelled disturbances. The robustness of all the AFC schemes are also ascertained in the study. (Author)

  4. A numerical investigation of flow around octopus-like arms: near-wake vortex patterns and force development.

    2015-01-01

    The fluid dynamics of cephalopods has so far received little attention in the literature, due to their complexity in structure and locomotion. The flow around octopuses, in particular, can be complicated due to their agile and dexterous arms, which frequently display some of the most diverse mechanisms of motion. The study of this flow amounts to a specific instance of the hydrodynamics problem for rough tapered cylinder geometries. The outstanding manipulative and locomotor skills of octopuses could inspire the development of advanced robotic arms, able to operate in fluid environments. Our primary aim was to study the hydrodynamic characteristics of such bio-inspired robotic models and to derive the hydrodynamic force coefficients as a concise description of the vortical flow effects. Utilizing computational fluid dynamic methods, the coefficients were computed on realistic morphologies of octopus-like arm models undergoing prescribed solid-body movements; such motions occur in nature for short durations in time, e.g. during reaching movements and exploratory behaviors. Numerical simulations were performed on translating, impulsively rotating, and maneuvering arms, around which the flow field structures were investigated. The results reveal in detail the generation of complex vortical flow structures around the moving arms. Hydrodynamic forces acting on a translating arm depend on the angle of incidence; forces generated during impulsive rotations of the arms are independent of their exact morphology and the angle of rotation; periodic motions based on a slow recovery and a fast power stroke are able to produce considerable propulsive thrust while harmonic motions are not. Parts of these results have been employed in bio-inspired models of underwater robotic mechanisms. This investigation may further assist elucidating the hydrodynamics underlying aspects of octopus locomotion and exploratory behaviors. PMID:24730546

    The Department of Energy Atmospheric Radiation Measurement (ARM) Program is developing a routine large-eddy simulation (LES) modeling framework at the ARM Climate Research Facility sites, known as the "LES ARM Symbiotic Simulation and Observation" (LASSO) Workflow. The routine simulations will be assessed using comprehensive ARM observations of the atmosphere and land-surface states, particularly cloud observations. Since small changes in thermodynamic profiles can manifest large changes in cloud properties, successful simulations require careful initialization, appropriate forcing, and possibly suitable lateral boundary conditions. We use a multiscale data assimilation (MS-DA) system as a major methodology for producing forcing datasets required by the LES modeling. The MS-DA will be implemented in the regional Weather Research and Forecasting (WRF) model at a cloud resolving resolution (~1 km). MS-DA leverages existing reanalyses (e.g., the NCEP North American Regional Reanalysis, NARR) and operational forecasting products (e.g. the North American Mesoscale Forecast System, NAM; the High-Resolution Rapid Refresh, HRRR) products, and takes advantage of ARM observations to directly constrain the spectra of horizontal scales down to a few km. The analysis from the MS-DA allows deriving initial conditions and forcing datasets for a range of spatial and temporal scales, developing hydrometeor forcing, exploring time-varying boundary conditions, and diagnosing other needed thermodynamic variables. It is stressed that the datasets from the MS-DA are integrated with datasets from other sources to form ensembles to account for uncertainties. The methodologies, implementation and evaluations are presented.

    Full Text Available The Revolutionary Armed Forces of Colombia (FARC have been one of the world's most consistently formidable violent non-state actors over the last forty years. Unsurprisingly, the group has provided one of the most compelling and concerning examples of the level of technical sophistication attainable by sub-state organizations. Over the last two decades the group has carried out an iterative and innovative process that, in reaction to improved detection capabilities, has brought them from depending on disposable go-fast boats to transport drugs to possessing fully submersible and reusable covert vessels for transportation. The following case study will discuss the development of narco-submarines and the underlying motivations behind the pursuit of this complex engineering task. The case study will outline the different phases of the narco-submarine development and highlight FARC’s determination to overcome the challenges present in each design. This discussion will show how FARC’s systematized acquiring of information and expertise has resulted in the accomplishment of fully submersible vessels, capable of transporting more than 10 tons of illicit product.

    There is an integral connection between leadership, mentoring and professional career progression within the nursing profession. The purpose of this article is to examine recommendations and best practices from the literature and provide a basis to construct a formalized successful mentoring dyad program with guidelines on establishing and maintaining a productive mentoring relationship over long distance. Canadian Armed Forces (CAF) nurses practice within a unique domain both domestically and abroad. The military environment incorporates many aspects of mentoring that could benefit significantly by distance interchange. Supported through examining literature within nursing, CAF publications and other professions along with contrasting successful distance mentoring programs, the findings suggest that a top-down, leadership-driven formal mentoring program could be beneficial to CAF nurses. The literature review outlines definitions of terms for mentorship and distance mentoring or e-mentoring. A cross section of technology is now embedded in all work environments with personal communication devices commonplace. Establishing mentoring relationships from afar is practical and feasible. This article provides a guided discussion for nursing leaders, managers and grassroots nurses to implement mentoring programs over distances. The recommendations and findings of this article could have universal applications to isolated nursing environments outside of Canadian military operational frameworks. PMID:26560257

    Full Text Available This paper, through the narratives of activists and Meira Paibis reiterates the slogan—repeal the Armed Forces Special Powers Act (AFSPA, which is draconian and anti-people in spirit. The atroci- ty, which has been meted out on the people of Manipur because of this Act, is a profound viola- tion of human rights. Rape, mindless killings, kidnapping, fake encounters have been normalised by virtue of this Act. The youths have been badly affected due to the conflict emerging out of this Act which treats people in Manipur as ‘objects’ against the imagined boundaries of the Indian na- tion-state for security from the neighbouring nations. In this process, the lived experiences of the people have been pushed to the periphery against the massive motive of the state to protect bor- ders and the imagined nation, which is a direct offshoot of the legacy of colonialism in India. The paper has tried to capture the history of Manipur on a capsule to concretise the struggle of Irom Sharmila and the ‘hopes’ she gives to the people of Manipur for ‘peace’ and ‘justice’. Alongside, it makes a humble attempt to describe the ‘life’ of Irom Sharmila. In addition, it describes the rage of Manipuris, which have given rise to insurgency asking for ‘freedom’ through various platforms.

    2012-03-01

    In the German Armed Forces sports activities should bring the benefits of good health and trained fitness which are the hallmarks of sportsmen. In order to achieve this aim it is important to avoid accidents which negate the benefit of sports. Until today there appear to be no studies in existence which demonstrate the risk factors of sports activities undertaken while in military service. Equivalent studies on civilian sport activities are scarcely comparable. To find out risk factors for accidents with any period of recovery we followed sports accidents while on duty in a German barracks with 4,300 soldiers over a two-year period. Additionally we asked about the time needed for recovery from each accident, parameters of lifestyle, the body mass index and the possibility of a nightshift before each accident. We examined a minimum of 410 accidents. We found associations between the accidents studied and particular risk factors, including doing sports more than two times a week, being active in a fitness or sports club, having the accident together with another sportsman and doing a nightshift before the day of the accident. Bad ground conditions contributed to a large number of accidents. A body mass index of 25 and higher had a significantly prolonged time for recovery. To avoid accidents, sport and ground conditions should be adapted to each other. In addition, overweight people are not only compromised for cardiovascular and neurological diseases but also have a higher risk of needing a prolonged time for recovery, thus it is important that overweight should be avoided and not only just be treated.

    2015-11-01

    In 2013, the Canadian Armed Forces (CAF) implemented the Fitness for Operational Requirements of Canadian Armed Forces Employment (FORCE), a field expedient fitness test designed to predict the physical requirements of completing common military tasks. Given that attaining this minimal physical fitness standard may not represent a challenge to some personnel, a fitness incentive program was requested by the chain of command to recognize and reward fitness over and above the minimal standard. At the same time, it was determined that the CAF would benefit from a measure of general health-related fitness, in addition to this measure of operational fitness. The resulting incentive program structure is based on gender and 8 age categories. The results on the 4 elements of the FORCE evaluation were converted to a point scale from which normative scores were derived, where the median score corresponds to the bronze level, and silver, gold, and platinum correspond to a score which is 1, 2, and 3 SDs above this median, respectively. A suite of rewards including merit board point toward promotions and recognition on the uniform and material rewards was developed. A separate group rewards program was also tabled, to recognize achievements in fitness at the unit level. For general fitness, oxygen capacity was derived from FORCE evaluation results and combined with a measure of abdominal circumference. Fitness categories were determined based on relative risks of mortality and morbidity for each age and gender group. Pilot testing of this entire program was performed with 624 participants to assess participants' reactions to the enhanced test, and also to verify logistical aspects of the electronic data capture, calculation, and transfer system. The newly dubbed fitness profile program was subsequently approved by the senior leadership of the CAF and is scheduled to begin a phased implementation in June 2015. PMID:26506187

    Full Text Available Responde-se de maneira estrutural à pergunta: para que se tem Forças Armadas no Brasil? Isso leva a um trajeto expositivo que considera os contextos estratégicos e domésticos à luz das determinações constitucionais e dos termos de acordos internacionais que constrangem as alternativas brasileiras de uso de força. Conclui-se que o Brasil tem apenas três tarefas concretas para suas Forças Armadas: a defesa do território, a participação em ações internacionais e a garantia da lei e da ordem, circunscrito em todos os casos ao uso de armamentos convencionais. Responde-se à pergunta de partida afirmando que se tem Forças Armadas para sustentar a capacidade de realizar estas tarefas ao longo do tempo e em qualquer momento. Como e quanto se sustenta tal capacidade são os critérios essenciais para a formulação, condução e avaliação da política de defesa do Brasil.This article offers a structural answer to the question: what are Brazil's armed forces for? This leads to the appreciation of Brazil's strategic and domestic contexts of the use of armed force. It considers the constitutional imperatives and the terms of international agreements that curtail Brazilian alternatives. It argues that Brazil has only three concrete tasks for its armed forces: the defense of its territory, the participation in international missions, and the guarantee of law and order, being constrained further to the use of conventional weapons. It answers the question it began with as follows: Brazil's armed forces exist to sustain the capacity of carrying out these tasks over time and at any time. It concludes that how and how well a Brazilian defense policy sustains this capacity are the paramount criteria for its conception, management and evaluation.

  9. Forced arm use is superior to voluntary training for motor recovery and brain plasticity after cortical ischemia in rats

    Science.gov (United States)

    2014-01-01

    Background and purpose Both the immobilization of the unaffected arm combined with physical therapy (forced arm use, FAU) and voluntary exercise (VE) as model for enriched environment are promising approaches to enhance recovery after stroke. The genomic mechanisms involved in long-term plasticity changes after different means of rehabilitative training post-stroke are largely unexplored. The present investigation explored the effects of these physical therapies on behavioral recovery and molecular markers of regeneration after experimental ischemia. Methods 42 Wistar rats were randomly treated with either forced arm use (FAU, 1-sleeve plaster cast onto unaffected limb at 8/10 days), voluntary exercise (VE, connection of a freely accessible running wheel to cage), or controls with no access to a running wheel for 10 days starting at 48 hours after photothrombotic stroke of the sensorimotor cortex. Functional outcome was measured using sensorimotor test before ischemia, after ischemia, after the training period of 10 days, at 3 and 4 weeks after ischemia. Global gene expression changes were assessed from the ipsi- and contralateral cortex and the hippocampus. Results FAU-treated animals demonstrated significantly improved functional recovery compared to the VE-treated group. Both were superior to cage control. A large number of genes are altered by both training paradigms in the ipsi- and contralateral cortex and the hippocampus. Overall, the extent of changes observed correlated well with the functional recovery obtained. One category of genes overrepresented in the gene set is linked to neuronal plasticity processes, containing marker genes such as the NMDA 2a receptor, PKC ζ, NTRK2, or MAP 1b. Conclusions We show that physical training after photothrombotic stroke significantly and permanently improves functional recovery after stroke, and that forced arm training is clearly superior to voluntary running training. The behavioral outcomes seen correlate with

    A possible mechanism by which disodium cromoglycate (DSCG) prevents a decrease in regional cerebral blood flow but not hypotension in primates following whole body gamma irradiation was studied. Several studies have implicated superoxide radicals in intestinal and cerebral vascular disorders following ischemia and ionizing radiation, respectively, The superoxide radical is formed during radiolysis in the reaction between hydrated electrons and dissolved oxygen. For this reason, the efficiency of DSCG to scavenge hydrated electrons and possibly prevent the formation of the superoxide radical was studied. The results show that DSCG is an efficient hydrated-electrons scavenger and may effectively compete with oxygen for hydrated electrons preventing the radiolytic formation of the superoxide radicals.

    As of early January 2005, the French Armed Forces Health Services were on the ground in Indonesia to contribute to relief operations following the tsunami in Indonesia on December 26, 2004. Findings of preliminary investigation performed upon deployment of the first French elements demonstrated that a major priority was to speed up vaccination against measles in children between the ages of 6 months and 15 years. A vaccination campaign was planned in cooperation with Indonesian authorities and UNICEF. Implementation involved training of personnel and setting up vaccination clinics in refugee camps, schools, and neighborhoods in the city of Meulaboh. The vaccination campaign was hampered by a number of problems in particular involving logistics and required constant supervision. A survey to evaluate the results of the campaign in terms of vaccination coverage showed that the objective of vaccinating 70% of children in refugee camps was achieved. The survey provided other child health indicators that will be helpful to local authorities taking over after the departure of the French Armed Forces Health Services. PMID:16038345

    This paper describes a mechanical technique to reduce the nozzle reaction force of a sandblasting rig. A theoretical evaluation of the magnitudes and direction of action of typical sandblasting nozzle forces has been conducted and a technique for exploiting available energy in order to reduce the magnitude of the forces at the nozzle has been developed.Experimental results from a variety of tests in different configurations have confirmed the theoretically determined force magnitude's accuracy and shown that forces of up to 106N can be present in typical sandblasting operations. The results have also shown that an up to 77% reduction of force at the nozzle can be achieved by applying the developed mechanicaltechnique.

    The report provides a basis for the Armed Forces long-term planning, and how changes in the global energy supply may mean new challenges and threats, as well as the advantages and disadvantages that can be associated with different future energy solutions for Armed Forces own activities, primarily relating to fuel and power during operation. One conclusion is that the potential conflict between energy security and climate-security can lead to far-reaching security implications and that continued global fossil dependency contributes to increased safety of political and military focus on a number of potential conflicts. A new such area may be the Arctic, as in the wake of climate change will become available for exploitation. Large scale global renewable energy can bring greater geographical spread - and reduced pressure on existing 'hot-spots'. Nuclear power is unlikely to be influential in the overall global energy security, but security problems associated with the production of nuclear materials can spread and be strengthened. Furthermore, the energy problems of connected to gaps between rich and poor, which may lead to social friction and conflict. The trend toward increased nationalisation and politicization of the energy is in contrast to free trade and market liberalism and may lead to further militarization of energy resources. Bilateral energy contracts may result in division within the EU and create a hindrance to joint positions and actions, such as in international efforts. As for Armed Forces own future energy solutions, the knowledge of alternative fuels (eg alcohols, diesel variants, gaseous fuels) and energy converters (eg hybrid vehicles, fuel cells) is reviewed. The following alternative principle solutions fuel and power are discussed: 1. Power from small-scale electricity generation via solar cells and small wind farms and power stations with liquid fuel as a supplement. Transport with plug-in hybrid vehicles, i.e. liquid propellants in

    There is a paucity of evidence to show the importance of morale within military units. The aim of this study was to explore how pre-enlistment and postenlistment factors influence morale and to ascertain which has the greater contribution. A cross-sectional study of the UK military involved in operations to Iraq was conducted between 2004 and 2006. The sample was randomly selected and was representative of the UK Armed Forces. Data were collected via questionnaires and included measures on unit cohesion and leadership, childhood adversity, and current service factors (e.g., whether individuals deployed as individuals or within formed units). Although childhood adversity was found to affect self-reported morale, current service factors were found to have a greater influence. PMID:21305954

    Approximately 60-70% of Armed Forces personnel consume a dietary supplement (DS) at least once a week and there have been numerous reports of severe adverse events among DS users. This study assessed patterns of DS use and self-reported side-effects among 4400 Armed Forces personnel using a paper-and-pencil survey. Multivariable logistic regression was used to examine associations between patterns of DS use and self-reported side-effects. Sixty-nine percent of personnel surveyed reported using a DS. Seven percent of DS users reported experiencing abnormal heart beats, 6% tremors, 5% stomach pain, 3% dizziness, and 3% numbness/tingling and they believed these symptoms were associated with the use of DS. After adjustment for use of other DS classes, total supplement use, and demographic characteristics, protein supplement users were more likely than non-users to report numbness/tingling; combination product users were more likely to report experiencing abnormal heart beats, stomach pain, dizziness, tremors, and numbness/tingling; and users of purported steroid analogues were more likely to report dizziness. Use of more than one DS per week was associated with an increased likelihood of reporting side-effects. Respondents with a higher body mass index were more likely to report side-effects. Further research is necessary to determine whether self-reported side-effects associated with multiple DS use and some DS classes impact the long-term health or performance of service members. Surveillance of military populations using surveys like this one may provide a method for detecting adverse health events of DS before they are apparent in the civilian population.

    2006-01-01

    Data collected at the Department of Energy Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) Central Facility (SCF) are analyzed to determine the monthly and hourly variations of cloud fraction and radiative forcing between January 1997 and December 2002. Cloud fractions are estimated for total cloud cover and for single-layered low (0-3 km), middle (3-6 km), and high clouds (more than 6 km) using ARM SCG ground-based paired lidar-radar measurements. Shortwave (SW) and longwave (LW) fluxes are derived from up- and down-looking standard precision spectral pyranometers and precision infrared radiometer measurements with uncertainties of approximately 10 Wm(exp -2). The annual averages of total, and single-layered low, middle and high cloud fractions are 0.49, 0.11, 0.03, and 0.17, respectively. Both total and low cloud amounts peak during January and February and reach a minimum during July and August, high clouds occur more frequently than other types of clouds with a peak in summer. The average annual downwelling surface SW fluxes for total and low clouds (151 and 138 Wm(exp-2), respectively) are less than those under middle and high clouds (188 and 201 Wm(exp -2), respectively), but the downwelling LW fluxes (349 and 356 Wm(exp -2)) underneath total and low clouds are greater than those from middle and high clouds (337 and 333 Wm(exp -2)). Low clouds produce the largest LW warming (55 Wm(exp -2) and SW cooling (-91 Wm(exp -2)) effects with maximum and minimum absolute values in spring and summer, respectively. High clouds have the smallest LW warming (17 Wm(exp -2)) and SW cooling (-37 Wm(exp -2)) effects at the surface. All-sky SW CRF decreases and LW CRF increases with increasing cloud fraction with mean slopes of -0.984 and 0.616 Wm(exp -2)%(exp -1), respectively. Over the entire diurnal cycle, clouds deplete the amount of surface insolation more than they add to the downwelling LW flux. The calculated CRFs do not appear to be significantly

    Full Text Available A substantial amount of research has been conducted into the mental health of the UK military in recent years. This article summarises the results of the various studies and offers possible explanations for differences in findings between the UK and other allied nations. Post-traumatic stress disorder (PTSD rates are perhaps surprisingly low amongst British forces, with prevalence rates of around 4% in personnel who have deployed, rising to 6% in combat troops, despite the high tempo of operations in recent years. The rates in personnel currently on operations are consistently lower than these. Explanations for the lower PTSD prevalence in British troops include variations in combat exposures, demographic differences, higher leader to enlisted soldier ratios, shorter operational tour lengths and differences in access to long-term health care between countries. Delayed-onset PTSD was recently found to be more common than previously supposed, accounting for nearly half of all PTSD cases; however, many of these had sub-syndromal PTSD predating the onset of the full disorder. Rates of common mental health disorders in UK troops are similar or higher to those of the general population, and overall operational deployments are not associated with an increase in mental health problems in UK regular forces. However, there does appear to be a correlation between both deployment and increased alcohol misuse and post-deployment violence in combat troops. Unlike for regular forces, there is an overall association between deployment and mental health problems in Reservists. There have been growing concerns regarding mild traumatic brain injury, though this appears to be low in British troops with an overall prevalence of 4.4% in comparison with 15% in the US military. The current strategies for detection and treatment of mental health problems in British forces are also described. The stance of the UK military is that psychological welfare of troops is

    Data collected at the Department of Energy Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) central facility are analyzed for determining the variability of cloud fraction and radiative forcing at several temporal scales between January 1997 and December 2002. Cloud fractions are estimated for total cloud cover and for single-layer low (0-3 km), middle (3-6 km), and high clouds (greater than 6 km) using ARM SGP ground-based paired lidar-radar measurements. Shortwave (SW), longwave (LW), and net cloud radiative forcings (CRF) are derived from up- and down-looking standard precision spectral pyranometers and precision infrared radiometer measurements. The annual averages of total, and single-layer, nonoverlapped low, middle and high cloud fractions are 0.49, 0.11, 0.03, and 0.17, respectively. Total and low cloud amounts were greatest from December through March and least during July and August. The monthly variation of high cloud amount is relatively small with a broad maximum from May to August. During winter, total cloud cover varies diurnally with a small amplitude, mid-morning maximum and early evening minimum, and during summer it changes by more than 0.14 over the daily cycle with a pronounced early evening minimum. The diurnal variations of mean single-layer cloud cover change with season and cloud height. Annual averages of all-sky, total, and single-layer high, middle, and low LW CRFs are 21.4, 40.2, 16.7, 27.2, and 55.0 Wm(sup -2), respectively; and their SW CRFs are -41.5, -77.2, -37.0, -47.0, and -90.5 Wm(sup -2). Their net CRFs range from -20 to -37 Wm(sup -2). For all-sky, total, and low clouds, the maximum negative net CRFs of -40.1, -70, and -69.5 Wm(sup -2), occur during April; while the respective minimum values of -3.9, -5.7, and -4.6 Wm(sup -2), are found during December. July is the month having maximum negative net CRF of -46.2 Wm(sup -2) for middle clouds, and May has the maximum value of -45.9 Wm(sup -2) for high clouds. An

We performed a quasi-experimental study among 102 soldiers of the Serbian Armed Forces. The experimental intervention consisted of the HIV knowledge pre-questionnaire, watching a film on HIV knowledge, then the post-HIV knowledge questionnaire. The results of pre-and post-HIV knowledge questionnaires were compared. Results. There were 23 questions in the test. The average total score on the questionnaire before watching the film was 18.23 and after watching it was 20.14, which was statistically significant difference (p < 0.001. Conclusions. The results of the study show that viewing a film on HIV infection is an effective method of transferring knowledge about HIV to the Serbian military population.

  10. Armed forces career exploration for high school students in the fields of engineering and science. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1993-08-01

    Morgan State University`s School of Engineering conducted its third annual Armed Forces Career Exploration program for high school students in the fields of engineering and science. The four week program was jointly sponsored by the US Army Laboratory Command (Ballistics Research Laboratory and Human Engineering Laboratory) and US Department of Energy (Los Alamos National Laboratory). The environment in a predominantly urban school system is such that a significant number of very capable students reach the eleventh grade without plans for the future. These students as a result of teacher influence have taken lower level math and science courses and we feel by participating in this program will see reasons for pursuing higher level math and science courses their last two years in high school. Inasmuch as intervention programs have not yet significantly affected the profile of these schools this pool of students represents an opportunity to make an early impact on the number of students that enter college intending to major in math, science or engineering. This report presents the program that provided selected students with pre-engineering and science enrichment experiences designed to enhance their understanding of engineering, increase their awareness of career opportunities in science and engineering, advance their readiness to enter temporary job situation, and foster the development of self-confidence in their individual capabilities.

  11. Diagnostic and therapeutic approaches after suspected or confirmed extraordinary exposure to ionizing radiation of members of the German Armed Forces

    International Nuclear Information System (INIS)

    This report refers to the results of 5 working packages. The first of them deals in detail with 11 extraordinary radiation accidents resulting in a chronic or protracted/intermittent radiation exposure. In most of the cases, the radiation etiology of observed health impairments was suspected many days, weeks or months after the beginning of accidental exposure. Therefore, in the second package, a review of results of systematic chronic radiation exposures in dogs, rats and mice was done to try to understand the pathophysiology of observations in man. The key problem lies in the day-by-day radiation effects on hemopoietic stem cells and their capability to cope with the radiation induced excess cell loss. On this basis, diagnostic approaches to assess the functional potentials of cell renewal are outlined in package 3. These considerations lead to therapeutic recommendations (package 4): in case of an irreversible damage to the stem cell pool, a stem cell transplantation may be the only way to induce recovery. In case of a reversible damage, the transient hemopoietic failure can be bridged by appropriate supportive measures to prevent infection or bleeding. The package 5 recommends to initiation of continuing medical education for the Armed Forces Medical Services to deal with this type of extraordinary radiation accidents which may occur in any 'out-of-area' - mission.

  12. The arms race control

    International Nuclear Information System (INIS)

    Written in 1961, this paper presents the content of a book entitled 'The arms race control' where the author outlined the difference between disarmament and arms control, described the economic and moral role of arms race, the importance of force balance for international security. He wandered whether arms control could ensure this balance and whether nuclear balance meant force balance. Force balance then appears to be a precarious and unsteady component of international security. He commented the challenges of disarmament, recalled some arguments for a nuclear disarmament. Then he discussed what would be an arms control with or without disarmament (either nuclear or conventional)

  16. Integration of gamma measuring equipment into an Agusta A109BA helicopter of the Belgian Armed Forces for use in emergency situations

    International Nuclear Information System (INIS)

    In case of a nuclear emergency, accidental releases of radioactive material might cause large scale environmental contamination. After the emergency has been brought under control, and the radioactive releases have settled on the ground, it is essential to map as quickly as possible the extent of the contaminated area and to evaluate the severity of the contamination. Airborne gamma measurements are known to be an effective means for quickly and safely mapping and evaluating large scale contaminations of gamma-emitting radio nuclides. We wanted to integrate gamma measuring equipment, based on a NaI detector, into an Agusta A109BA helicopter of the Belgian armed forces. This was done within the framework of ''Aid to the Nation'', a special program developed by the Belgian Armed Forces for facilitating cooperation between the armed forces and civilian organisations, for projects that are to the benefit of the Belgian Nation. Working in this framework, we also want to develop the necessary procedures that will allow quick and efficient deployment of the measuring capability in case of an emergency

  17. Strategic Renewal in Regulatory Environments. How inter- and intra-organisational institutional forces influence European incumbent energy firms

    Energy Technology Data Exchange (ETDEWEB)

    Stienstra, M.

    2008-11-20

    How do incumbent firms strategically renew in regulatory environments? Assuming that regulation can both constrain and enable a firm's strategic renewal opportunities, we investigate how and to what extent incumbent firms undertake exploitative and explorative strategic renewal actions in order to remain competitive. Exploitative strategic renewal involves those actions that strengthen or optimise a firm's current resource deployments, whereas explorative strategic renewal relates to actions that generate new sources of value creation for the firm. Based on old institutional theory, new institutional theory, neo-institutional theory and institutional entrepreneurship literature, a multi-level framework that combines selection and adaptation arguments has been developed and applied to investigate strategic renewal behaviour of a sample of European energy incumbents. At industry level of analysis, results show how inter-organisational institutional forces significantly impact firms' choices of exploitative and explorative strategic renewal actions through regulative, normative and cognitive forces. At organisational unit level of analysis, we find that the extent of intra-organisational regulative forces is positively related to exploitative strategic renewal actions. In addition, entrepreneurial proclivity appears to be a catalyst of both exploitative and explorative strategic renewal actions. Finally, our results provide insights how environmental selection and firm level adaptation are interrelated in the context of regulation. The extent of inter-organisational regulative forces positively moderates the relationship between intra-organisational regulative forces and exploitative strategic renewal actions.

    2015-12-01

    There is a paucity of information about the dental specialties related articles published in the Medical Journal Armed Forces India (MJAFI). This study aimed to audit the dental specialities related articles published in MJAFI from 2000 to 2014 over a 15-year period. Bibliometric analysis of sixty issues of MJAFI from 2000 to 2014 were performed using web-based search. The articles published were analyzed for type of article and topic of individual dental specialities. The articles published were also evaluated to identify whether the study was an Armed Forces Medical Research Committee Project or funded research project or not. Out of the total 118 published articles related to dental specialities, original articles (55) and case reports (49) contribute the major share. The highest number of dental specialities related articles was published in 2009 with 16, followed by 2010 with 13 and 2011 with 11 and the least published year was 2013 with 3 articles. Regarding the relationship with dental specialities, the maximum number of published articles were related to oral medicine and radiology (56) followed by oral and maxillofacial surgery (49), orthodontics (23) and prosthodontics (17). Among the articles published in MJAFI, maxillofacial injuries (11) followed by orthodontic treatment (8) and craniofacial deformities (8) form the major attraction of the contributors. Among the 118 dental speciality articles, there were only 4 Armed Forces Medical Research Committee Project articles and 19 funded research project articles. An equal distribution of articles related to clinical dentistry and nonclinical dentistry is maintained for the MJAFI from 2000 to 2014 over a 15-year period. PMID:26858474

    Full Text Available There is a relatively high incidence of screw misplacement during spinal instrumentation due to distortion of normal anatomy following spinal trauma. The O-arm® is the next-generation spinal navigation tool that provides intraoperative 3-D imaging for complex spine surgeries. In this prospective study over 1-month period, 25 patients (mean age 29.16 years (range 7-58 years, 22 (88% males with spinal injury who underwent spinal instrumentation under O-arm® guidance were included. Fall from height (64% was the most common etiology seen in 16 patients. The majority (68% had dorsolumbar fractures. Spinal canal compromise was seen in 21 patients (84%. Ten patients (40% had American Spinal Injury Association (ASIA grade A injuries, two patients (8% had grade B, five patients (20% had grade C, four patients (16% each had grade D, and grade E injuries. A total of 140 screws were inserted under O-arm guidance. Of these, 113 (81% were dorsolumbar pedicle screws, 2 were odontoid screws, 12 were anterior cervical screws, and 12 screws (48% were lateral mass screws. Mean duration of surgery was 4.5 h with a mean blood loss of 674 mL. The mean postoperative stay was 6.3 days. None of the patients had screw malplacement ort canal breach. No patient deteriorated in ASIA grade postoperatively. The system was rated as excellent for ease of use by all faculty using the system. Accurate screw placement provides better patient safety and reduces the in hospital stay thereby leading early patient mobilization and may reduce the cost incurred in patient management.

    2014-06-01

    Full Text Available Freedom of expression is one of the most fundamental rights in a democratic society. In fact, the freedom to express one’s opinion and to impart, as well as to receive, information, is essential for the participation in the democratic process. The ability to make decisions as a citizen requires access to information; the participation in the life of the society requires the ability to express one’s opinions. It is imperative that in a democratic society, as it is envisaged by the European Convention on Human Rights (ECHR, everybody is able to express their views, regardless as to whether these views correspond to the views of those who are in power. This ability is one of the key differences between democracy anddictatorship. In particular in the nation-states of Eastern Europe, which have only known freedom for a bit less than a quarter of a century, the growth of democratic structures is inextricably linked to the ability to exercise this right. But while human rights in principle pit the citizen against the State, the citizen who serves the State in a professional function might also wish to express opinions that go against the view of those who are entrusted with leading the State. This is particularly the case when it comes to members of the armed forces. The jurisprudence of the Convention organs with regard to the right of public officials and other State agents to express their opinion freely is not as coherent as it is with regard to other questions concerning the ECHR. In a case decided in late 2013, the European Court of Human Rights dealt with this question with regard to Lithuania. In this article, the authors look at the question of how far the State can restrict the freedom of expression of members of the armed forces under the European Convention on Human Rights.

    Full Text Available Adequate nutrition is very essential, especially for the Armed Forces, to buildup their nutritional reserveswhile deriving maximum benefits of training/peak performances in operational situations by keeping theirmorale high. The present study reviews/examines the adequacy of the existing ration scales of the ArmedForces personnel stationed under different terrain conditions of the country/recruits at various training centres.Food samples were collected from different strategic locations during different seasons of the year and analysedfor their nutrient composition like proximal constituents, vitamins A, E, B1, B2, C, and dietary fibre. Basedon the data generated, the daily nutrients/energy consumption by the soldiers/recruits, were calculated separatelyboth for personnel in plains and at high altitudes. Soldiers in plains, on an average consumed protein 124.2+ 13.0 g, fat 98.8 + 29.6 g and energy 3632+317 kcal/person/day, while their counterparts at high altitudesconsumed protein 120.4 + 11.2 g, fat 120.1 + 31.1 g, and energy 3906 + 423 kcal/person/day. The study clearlyindicate that the present ration scales for the Service personnel, both in plains and at high altitudes (9000 ftto 15000 ft is adequate wrt their nutrient density. It is however suggested to ensure adequate supply of goodquality fresh vegetables, fruits, and meat, which inturn would not only help to keep the morale of the soldiers,high and cheerful, especially at high altitudes, but will also enable adequate micronutrient availability. Thefibre levels in the diets of these soldiers have also been found to be well within the limits (20 -35 g/ person/day recommended for optimal health.Defence Science Journal, 2008, 58(6, pp.734-744, DOI:http://dx.doi.org/10.14429/dsj.58.1701

    Maternal phenylketonuria results in a high incidence of children born mentally retarded. We showed that the large neutral amino acids valine, isoleucine, and leucine (VIL) ameliorate the effects of intrauterine hyperphenylalaninemia in rats on a test of complex maze learning. To further test the ameliorative effects of VIL on intrauterine CNS development during hyperphenylalaninemia, gravid rats were administered a phenylalanine/p-chlorophenylalanine (index group) supplemented diet with or without VIL added. Controls were given standard diet with or without VIL. All groups were pair-fed to the index group. As adults, the progeny exposed in utero to hyperphenylalaninemia showed characteristic learning impairments in a complex water (Cincinnati) maze on forced and elective-choice phases of the task and deficits in radial-arm maze and Morris maze acquisition, whereas those exposed to hyperphenylalaninemia combined with VIL showed no deficits in the forced-choice phase of Cincinnati maze learning and no evidence of radial-arm maze deficits. However, the improvement was not complete, with no ameliorative effects obtained on the elective-choice phase of the Cincinnati maze or on the Morris hidden platform test. No deficits were seen on phases containing test trials for memory function (Olton and Morris mazes). The acquisition differences occurred in the absence of any effects of VIL on maternal weight gain during gestation, maternal serum amino acid concentrations of phenylalanine or tyrosine, or effects on offspring growth. VIL alone produced no adverse or enhancing effects on learning or memory. Based on these data it was concluded that the VIL supplement continues to show promise as a potential treatment for intrauterinely acquired mental deficiency associated with maternal phenylketonuria.

    Refractive surgery (RS) is a common procedure in the U.S. military population. This report provides an estimation of incident RS for vision correction purposes in the active component of the U.S. military from 1 January 2005 through 31 December 2014 and the prevalence of post-RS complications and eye disease in the 1-year period after RS. During the surveillance period, a total of 121,571 subjects without a diagnosis of eye disease other than hyperopia, myopia, or astigmatism in the previous year received a single incident RS procedure. In the 1-year period after RS, 5.3% of subjects with preoperative hyperopia or myopia had treatment-persistent (unresolved) hyperopia or myopia; 2.0% of subjects with preoperative astigmatism had treatment-persistent (unresolved) astigmatism; and 3.8% were diagnosed with tear film insufficiency. In general, most outcomes showed higher prevalences in Army and Air Force personnel versus Navy and Marine Corps personnel, in women versus men, in officer versus enlisted personnel, and in aviation and Special Forces personnel. A wide variation in outcome prevalences was noted by procedural military treatment facility. PMID:27255946

  17. Forces that direct the competition in the electric power industry in the new institutional scenery

    International Nuclear Information System (INIS)

    This work identifies the probable strategic characteristics of the interconnected North-Northeast Brazilian electricity industry, after the current restructuring and privatization process has been implemented. It is a 15.0 thousand MW generation industry supplying more than 33.5 million consumers. The normative scenery for analysis of the electricity industry takes into consideration the premises that the government establishes the vertical separation of generation, transmission, distribution and retailing, and introduces the regulation to a competitive industrial structure in generation and retailing. It is assumed that free access to transmit and distribute electricity and broad choices for consumers are the main features for competition in both generation and retailing. The essence of formulating strategy is to relate a company with its environment, considering the industrial structure. Porter's five forces model for industry environment and competition, emphasizing the role of the government in such regulated industry, is the basic theoretical reference. The main strategic characteristics related to entry barriers, rivalry intensity, supplier power, customer power and substitute products are analyzed. (author)

  18. 14. Policies and Institutions - Nongovernmental organizations: A growing force in the developing world

    International Nuclear Information System (INIS)

    An extraordinarily diverse and growing body of private organizations now dot the world's institutional landscape, working in a variety of areas such as small-scale local development, the conservation of tropical forests, and sustainable agriculture. Working at many levels, through example or advocacy these groups are influencing the direction of environment and development policy around the world. Non-governmental organizations (NGOs) are extraordinarily diverse. This chapter provides a few examples to capture some of that diversity, but focuses mainly on the strengths and weaknesses of NGOs, on the relationship between governments and NGOs, and on some emerging trends. The chapter primarily concerns the newly emerging grassroots and service NGOs in developing countries and those Northern NGOs that work extensively in developing countries. Topics discussed are: origins and regional differences (northern NGOs with a mission in the south, Asia, Latin America, Africa); strengths and weaknesses; key organizational factors (getting started, getting bigger, the impact of leadership, the role of women); government-NGO relations; emerging trends (evolving North-South relations, networks and associations - forging larger alliances, the information explosion global networking, new roles for policy research and legal defense)

    Full Text Available Background/Aim. Wars of the nineties in former Yugoslavia, Somalia, Rwanda imposed new tasks to the United Nations (UN forces, such as providing humanitarian aid, protection of civilians, peacekeeping, and in many instances providing armed enforcement of peace. The aim of this study was an observational analysis of Serbian participation in the UNs Mission in the Democratic Republic of Congo with the emphasis on stress and coping techniques. Methods. Serbian contribution in this mission dates back to April 2003 till the present days with a military contingent consisting of six members as a part of Air Medical Evacuation Team. The observed stressogenous factors acted before arrival to the mission area and in the mission area. In this paper we analysed ways to overcome them. Results. The productive ways of overwhelming stress used in this mission were: honesty and openness in interpersonal communications, dedication to work, maintaining discipline and order, strict following of appropriate regime of work, diet, rest and recreation; regular communication with family and organizing and participation in various social, cultural and sports manifestations. Conclusion. This analysis indicates that out of all the observed factors, the most important is appropriate selection of personnel.

There are no other civilian institutions involved in the control of the military. However, the armed forces of Venezuela have shown very stro...

  4. Intercomparison of lateral scales of scanning electron microscopes and atomic force microscopes in research institutes in Northern Europe

    International Nuclear Information System (INIS)

    An intercomparison of lateral scales of scanning electron microscopes (SEM) and atomic force microscopes (AFM) in various research laboratories in Northern Europe was organized by the local national metrology institutes. In this paper are presented the results of the comparison, with also an example uncertainty budget for AFM grating pitch measurement. Grating samples (1D) were circulated among the participating laboratories. The participating laboratories were also asked about the calibration of their instruments. The accuracy of the uncertainty estimates seemed to vary largely between the laboratories, and for some laboratories the appropriateness of the calibration procedures could be considered. Several institutes (60% of all results in terms of En value) also had good comprehension of their measurement capability. The average difference from reference value was 6.7 and 10.0 nm for calibrated instruments and 20.6 and 39.9 nm for uncalibrated instruments for 300 nm and 700 nm gratings, respectively. The correlation of the results for both nominally 300 and 700 nm gratings shows that a simple scale factor calibration would have corrected a large part of the deviations from the reference values.

    Cardiomyopathies are a group of heterogeneous myocardial diseases that are frequently inherited and are a recognised cause of premature sudden cardiac death in young individuals. Incomplete expressions of disease and the overlap with the physiological cardiac manifestations of regular intensive exercise create diagnostic challenges in young athletes and military recruits. Early identification is important because sudden death in the absence of prodromal symptoms is a common presentation, and there are several therapeutic strategies to minimise this risk. This paper examines the classification and clinical features of cardiomyopathies with specific reference to a military population and provides a detailed account of the optimum strategy for diagnosis, indications for specialist referral and specific guidance on the occupational significance of cardiomyopathy. A 27-year-old Lance Corporal Signaller presents to his Regimental medical officer (RMO) after feeling 'light-headed' following an 8 mile unloaded run. While waiting to see the RMO, the medical sergeant records a 12-lead ECG. The ECG is reviewed by the RMO immediately prior to the consultation and shows voltage criteria for left ventricular (LV) hypertrophy and inverted T-waves in II, III, aVF and V1-V3 (Figure 1). This Lance Corporal is a unit physical training instructor and engages in >10 h of aerobic exercise per week. He is a non-smoker and does not have any significant medical history. PMID:26246349

    Bosi, F; Corso, F Dal; Bigoni, D

    2015-01-01

    The concept of 'deformable arm scale' (completely different from a traditional rigid arm balance) is theoretically introduced and experimentally validated. The idea is not intuitive, but is the result of nonlinear equilibrium kinematics of rods inducing configurational forces, so that deflection of the arms becomes necessary for the equilibrium, which would be impossible for a rigid system. In particular, the rigid arms of usual scales are replaced by a flexible elastic lamina, free of sliding in a frictionless and inclined sliding sleeve, which can reach a unique equilibrium configuration when two vertical dead loads are applied. Prototypes realized to demonstrate the feasibility of the system show a high accuracy in the measure of load within a certain range of use. It is finally shown that the presented results are strongly related to snaking of confined beams, with implications on locomotion of serpents, plumbing, and smart oil drilling.

    This image highlights the hidden spiral arms (blue) that were discovered around the nearby galaxy NGC 4625 by the ultraviolet eyes of NASA's Galaxy Evolution Explorer. The image is composed of ultraviolet and visible-light data, from the Galaxy Evolution Explorer and the California Institute of Technology's Digitized Sky Survey, respectively. Near-ultraviolet light is colored green; far-ultraviolet light is colored blue; and optical light is colored red. As the image demonstrates, the lengthy spiral arms are nearly invisible when viewed in optical light while bright in ultraviolet. This is because they are bustling with hot, newborn stars that radiate primarily ultraviolet light. The youthful arms are also very long, stretching out to a distance four times the size of the galaxy's core. They are part of the largest ultraviolet galactic disk discovered so far. Located 31 million light-years away in the constellation Canes Venatici, NGC 4625 is the closest galaxy ever seen with such a young halo of arms. It is slightly smaller than our Milky Way, both in size and mass. However, the fact that this galaxy's disk is forming stars very actively suggests that it might evolve into a more massive and mature galaxy resembling our own. The armless companion galaxy seen below NGC 4625 is called NGC 4618. Astronomers do not know why it lacks arms but speculate that it may have triggered the development of arms in NGC 4625.

    Skeletal structures act as lever arms during walking. Muscle activity and the ground reaction against gravity exert forces on the skeleton, which generate torque (moments) around joints. These lead to the sequence of movements which form normal human gait. Skeletal deformities in cerebral palsy (CP) affect the function of bones as lever arms and compromise gait. Lever arm dysfunction should be carefully considered when contemplating treatment to improve gait in children with CP.

  7. Response of the middle atmosphere to anthropogenic and natural forcings in the CMIP5 simulations with the Max Planck Institute Earth system model

    KAUST Repository

    Schmidt, H.

    2013-03-06

    The ECHAM6 atmospheric general circulation model is the atmosphere component of the Max Planck Institute Earth System Model (MPI-ESM) that is used in the Coupled Model Intercomparison Project Phase 5 (CMIP5) simulations. As ECHAM6 has its uppermost layer centered at 0.01 hPa in the upper mesosphere, these simulations offer the opportunity to study the middle atmosphere climate change and its relation to the troposphere on the basis of a very comprehensive set of state-of-the-art model simulations. The goals of this paper are (a) to introduce those new features of ECHAM6 particularly relevant for the middle atmosphere, including external forcing data, and (b) to evaluate the simulated middle atmosphere and describe the simulated response to natural and anthropogenic forcings. New features in ECHAM6 with respect to ECHAM5 include a new short-wave radiation scheme, the option to vary spectral irradiance independent of total solar irradiance, and a latitude-dependent gravity-wave source strength. The description of external forcing data focuses on solar irradiance and ozone. Stratospheric temperature trends simulated with the MPI-ESM for the last decades of the 20th century agree well with observations. The future projections depend strongly on the scenario. Under the high emission scenario RCP8.5, simulated temperatures are locally lower by more than 20 K than preindustrial values. Many of the simulated patterns of the responses to natural forcings as provided by solar variability, volcanic aerosols, and El Nino-Southern Oscillation, largely agree with the observations. 2013.

    Research into the psychosocial needs of children formerly associated with armed forces (CAAF) has aroused much interest in the past 60 years. Despite this, much debate remains surrounding how to optimally address these issues. The overwhelming stance of modern authors is that intervention must move away from the former focus on purely psychological intervention, to encompass broader social and cultural issues in addition. Hosted by Save the Children UK (SCUK), this qualitative research explores the perceptions of former CAAF, their communities and local SCUK staff of the psychosocial needs of former CAAF. Semi-structured interviews and focussed group discussions were conducted with 62 former CAAF (29 boys, 33 girls), 21 community members and 7 staff members of SCUK or its partner organizations in Beni and Lubero territories of North Kivu province, eastern Democratic Republic of Congo. Findings are presented and were analysed within a conceptual framework proposed by the Psychosocial Working Group. It was found that whilst the social needs of former CAAF and their communities are great, psychological challenges are prevalent and serious; moreover these psychological challenges impact the social integration of former CAAF. In addition, the needs of female former CAAF should be addressed differently to those of males, due primarily to the children most of the girls have conceived during their time with armed groups. The current movement of psychosocial theory from a psychological to a social focus is reflective of an attempt to address developmental concerns at the neglect of humanitarian needs. In consequence, former CAAF are being offered substandard assistance which fails to optimize their chances for successful civilian reintegration. PMID:19957306

    Cardiac catheterization is important in the diagnosis and risk stratification of pulmonary hypertensive vascular disease (PHVD) in children. Acute vasoreactivity testing provides key information about management, prognosis, therapeutic strategies, and efficacy. Data obtained at cardiac catheterization continue to play an important role in determining the surgical options for children with congenital heart disease and clinical evidence of increased pulmonary vascular resistance. The Pediatric and Congenital Heart Disease Task Forces of the Pulmonary Vascular Research Institute met to develop a consensus statement regarding indications for, conduct of, acute vasoreactivity testing with, and pitfalls and risks of cardiac catheterization in children with PHVD. This document contains the essentials of those discussions to provide a rationale for the hemodynamic assessment by cardiac catheterization of children with PHVD. PMID:27076908

    解放战争后期,尤其是辽沈、淮海、平津三大战役胜利结束以后,毛泽东审时度势,及时地提出了军队不仅是战斗队而且是工作队,要求军队干部应当学会接收、管理城市和新区工作,对促进当时新解放区干部问题的解决和革命事业的顺利发展起到了巨大的促进作用。在新世纪新阶段,我军要借鉴毛泽东的工作队经验。努力做到突出核心军事能力建设,注重非战争军事行动能力建设,注重培养“学习型”高素质复合型军事人才,为维护国家安全、社会稳定和经济发展作贡献。%In the later stage of War of Liberation,especially after Liaoxi-Shenyang,Huai-Hai and Beiping-Tianjing Campaigns, Mao Zedong, correctly appraising the situations, presented the thinking that the armed forces were not only a fighting team but also a working team,requiring that cadres should learn to take over and manage cities and new areas.That has played an important role in developing the cause of the revolution. In the new era,our armed forces should draw lessons from Mao Zedong's experience on the working team,strive to give prominence to improving the core military capacity, focus on the improvement of their unmilitary capacity, try hard to train "learning-oriented" high-quality composite type personnel, safeguard China's security and contribute to economic and social development.

    Embedding computational models in the physical world is a critical step towards constraining their behavior and building practical applications. Here we aim to drive a realistic musculoskeletal arm model using a biomimetic cortical spiking model, and make a robot arm reproduce the same trajectories in real time. Our cortical model consisted of a 3-layered cortex, composed of several hundred spiking model-neurons, which display physiologically realistic dynamics. We interconnected the cortical model to a two-joint musculoskeletal model of a human arm, with realistic anatomical and biomechanical properties. The virtual arm received muscle excitations from the neuronal model, and fed back proprioceptive information, forming a closed-loop system. The cortical model was trained using spike timing-dependent reinforcement learning to drive the virtual arm in a 2D reaching task. Limb position was used to simultaneously control a robot arm using an improved network interface. Virtual arm muscle activations responded to motoneuron firing rates, with virtual arm muscles lengths encoded via population coding in the proprioceptive population. After training, the virtual arm performed reaching movements which were smoother and more realistic than those obtained using a simplistic arm model. This system provided access to both spiking network properties and to arm biophysical properties, including muscle forces. The use of a musculoskeletal virtual arm and the improved control system allowed the robot arm to perform movements which were smoother than those reported in our previous paper using a simplistic arm. This work provides a novel approach consisting of bidirectionally connecting a cortical model to a realistic virtual arm, and using the system output to drive a robotic arm in real time. Our techniques are applicable to the future development of brain neuroprosthetic control systems, and may enable enhanced brain-machine interfaces with the possibility for finer control of

  17. Arms control: misplaced focus

    Most of the nuclear debate consists of arguments about which weapons systems should be built, controlled, canceled, frozen, or retired. Short of virtually complete, multilateral nuclear disarmament, however, no change in the pace, balance, or even the direction of the arms race can make much difference in the risk of nuclear war, the damage should one occur, or the division of international political power. This includes Star Wars, the nuclear freeze, and even large cuts in or stabilization of offensive nuclear arsenals. A better starting point for nuclear politics would be the insight that nuclear weapons have completely changed the logic of power as it has been handed down through the ages. Military force, perfected to its highest level, has invalidated itself - for in a nuclearized world, any resort to force by a nuclear power risks escalation to its ultimate level, and thus to oblivion for all. Trying to rationalize and control the ultimate force is far less realistic and important than limiting the provocation of conflict and the use of force at lower, non-nuclear levels - by the United States, it clients, and, to the extent possible, its adversaries. 13 references.

    Vector-borne infections (VBI) are defined as infectious diseases transmitted by the bite or mechanical transfer of arthropod vectors. They constitute a significant proportion of the global infectious disease burden. United States (U.S.) Department of Defense (DoD) personnel are especially vulnerable to VBIs due to occupational contact with arthropod vectors, immunological naiveté to previously unencountered pathogens, and limited diagnostic and treatment options available in the austere and unstable environments sometimes associated with military operations. In addition to the risk uniquely encountered by military populations, other factors have driven the worldwide emergence of VBIs. Unprecedented levels of global travel, tourism and trade, and blurred lines of demarcation between zoonotic VBI reservoirs and human populations increase vector exposure. Urban growth in previously undeveloped regions and perturbations in global weather patterns also contribute to the rise of VBIs. The Armed Forces Health Surveillance Center-Global Emerging Infections Surveillance and Response System (AFHSC-GEIS) and its partners at DoD overseas laboratories form a network to better characterize the nature, emergence and growth of VBIs globally. In 2009 the network tested 19,730 specimens from 25 sites for Plasmodium species and malaria drug resistance phenotypes and nearly another 10,000 samples to determine the etiologies of non-Plasmodium species VBIs from regions spanning from Oceania to Africa, South America, and northeast, south and Southeast Asia. This review describes recent VBI-related epidemiological studies conducted by AFHSC-GEIS partner laboratories within the OCONUS DoD laboratory network emphasizing their impact on human populations.

    2012-01-01

    In order to understand the physical mechanisms underlying non-steady stellar spiral arms in disk galaxies, we analyzed the growing and damping phases of their spiral arms using three-dimensional $N$-body simulations. We confirmed that the spiral arms are formed due to a swing amplification mechanism that reinforces density enhancement as a seeded wake. In the damping phase, the Coriolis force exerted on a portion of the arm surpasses the gravitational force that acts to shrink the portion. Consequently, the stars in the portion escape from the arm, and subsequently they form a new arm at a different location. The time-dependent nature of the spiral arms are originated in the continual repetition of this non-linear phenomenon. Since a spiral arm does not rigidly rotate, but follows the galactic differential rotation, the stars in the arm rotate at almost the same rate as the arm. In other words, every single position in the arm can be regarded as the co-rotation point. Due to interaction with their host arms, ...

    In order to understand the physical mechanisms underlying non-steady stellar spiral arms in disk galaxies, we analyzed the growing and damping phases of their spiral arms using three-dimensional N-body simulations. We confirmed that the spiral arms are formed due to a swing amplification mechanism that reinforces density enhancement as a seeded wake. In the damping phase, the Coriolis force exerted on a portion of the arm surpasses the gravitational force that acts to shrink the portion. Consequently, the stars in the portion escape from the arm, and subsequently they form a new arm at a different location. The time-dependent nature of the spiral arms originates in the continual repetition of this nonlinear phenomenon. Since a spiral arm does not rigidly rotate, but follows the galactic differential rotation, the stars in the arm rotate at almost the same rate as the arm. In other words, every single position in the arm can be regarded as the corotation point. Due to interaction with their host arms, the energy and angular momentum of the stars change, thereby causing radial migration of the stars. During this process, the kinetic energy of random motion (random energy) of the stars does not significantly increase, and the disk remains dynamically cold. Owing to this low degree of disk heating, short-lived spiral arms can recurrently develop over many rotational periods. The resultant structure of the spiral arms in the N-body simulations is consistent with the observational nature of spiral galaxies. We conclude that the formation and structure of spiral arms in isolated disk galaxies can be reasonably understood by nonlinear interactions between a spiral arm and its constituent stars.

  8. Nuclear arms: ethics, strategy, politics

    Energy Technology Data Exchange (ETDEWEB)

    Woolsey, R.J. (ed.)

    1984-01-01

    The range of debate over strategy and arms control today is broader than it was in the late 1950s and early 1960s. In part this is because the early 1980s debate has involved questioning of the fundamental notion of deterrence - by no less than the American Catholic bishops. Today's debate has also seen a national nuclear freeze campaign that, although its congressional supporters have held firmly to a bilateral approach, was tilted perceptibly towards unilateralism by noncongressional leaders at their national conference in February 1983. In one way or another the authors wrestle with different aspects of one central question: could the beginning steps for any consensus be possible, in today's climate, on strategic issues. Ethical issues are addressed in the first 3 papers: Charles Krauthammer, On Nuclear Morality; Patrick Glynn, The Moral Case for the Arms Buildup; and Michael Quinlarc, Thinking Deterrence Through. Three chapters on strategic considerations include: Brent Snowcroft, Understanding the US Strategic Arsenal; William J. Perry, Technological Prospects for US Strategic Forces; and Richard Burt, The Strategic and Political Lessons of INF. Arms control and politics is treated in chapters by: Walter B. Slocombe, Arms Control: Prospects; and Colin S. Gray, Arms Control: Problems. The nonnuclear dimensions of strategy are discussed in chapters by Amory B. and L. Hunter Lovins, Reducing Vulnerability - The Energy Jugular; and Robert Kupperman, Vulnerable America. The chapters on space and defense are: Hans Mark, Arms Control and Space Technology; and Newt Gingrich and John Madison, Space and National Defense. The concluding chapters are by Sen. Sam Nunn, The Need to Reshape Military Stategy; and the editor, R. James Woolsey, The Politics of Vulnerability, 1980-1983.

    Directory of Open Access Journals (Sweden)

    Elizabeth B. Brokaw, MS

    2011-05-01

    Full Text Available We have developed a haptic-based approach for retraining of interjoint coordination following stroke called time-independent functional training (TIFT and implemented this mode in the ARMin III robotic exoskeleton. The ARMin III robot was developed by Drs. Robert Riener and Tobias Nef at the Swiss Federal Institute of Technology Zurich (Eidgenossische Technische Hochschule Zurich, or ETH Zurich, in Zurich, Switzerland. In the TIFT mode, the robot maintains arm movements within the proper kinematic trajectory via haptic walls at each joint. These arm movements focus training of interjoint coordination with highly intuitive real-time feedback of perform-ance; arm movements advance within the trajectory only if their movement coordination is correct. In initial testing, 37 nondisabled subjects received a single session of learning of a complex pattern. Subjects were randomized to TIFT or visual demonstration or moved along with the robot as it moved though the pattern (time-dependent [TD] training. We examined visual demonstration to separate the effects of action observation on motor learning from the effects of the two haptic guidance methods. During these training trials, TIFT subjects reduced error and interaction forces between the robot and arm, while TD subject performance did not change. All groups showed significant learning of the trajectory during unassisted recall trials, but we observed no difference in learning between groups, possibly because this learning task is dominated by vision. Further testing in stroke populations is warranted.

    Lee, Sukhan; Kim, Sungbok

    1990-01-01

    Dual-arm dynamic operation quality measures are presented which quantify the efficiency and capability of generating Cartesian accelerations by two cooperative arms based on the analysis of dual-arm dynamic interactions. Dual-arm dynamic manipulability is defined as the efficiency of generating Cartesian accelerations under the dynamic and kinematic interactions between individual arms and an object under manipulation. The analysis of dual-arm dynamic interactions is based on the so-called Cartesian space agent model of an arm, which represents an individual arm as a force source acting upon a point mass with the effective Cartesian space arm dynamics and an environment or an object under manipulation. The Cartesian space agent model of an arm makes it possible to derive the dynamic and kinematic constraints involved in the transport, assembly and grasping modes of dual-arm cooperation. A task-oriented operational quality measure, (TOQd) is defined by evaluating dual-arm dynamic manipulability in terms of given task requirements. TOQd is used in dual-arm joint configuration optimization. Simulation results are shown. A complete set of forward dynamic equations for a dual-arm system is derived, and dual-arm dynamic operational quality measures for various modes of dual-arm cooperation allowing sliding contacts are established.

    A multiple arm generalized compliant motion robot control system governs dual multi-joint robot arms handling an object with both of the arms in accordance with input parameters governing plural respective behaviors to be exhibited by the robot in respective behavior spaces simultaneously. A move-squeeze decomposition processor computes actual move and squeeze decomposition forces based upon current robot force sensor outputs. A compliant motion processor transforms plural object position perturbations of the plural behaviors from the respective behavior spaces to a common space and computes a relative transformation to a behavior-commanded object position in accordance with the object position perturbations of the plural behaviors. A kinematics processor updates a transformation to a current commanded object position based upon the relative transformation to the behavior-commanded object position. A multiple arm squeeze control processor computes from appropriate squeeze force input parameters and from actual squeeze forces for each of the arms, a squeeze control position perturbation for each of the arms, to provide squeeze control. An inverse kinematics processor computes from the commanded object position transformation and from the squeeze control position perturbation, new robot joint angles, and controls respective joints of the robot arms in accordance with the new robot joint angles.

    A multiple arm generalized compliant motion robot control system governs dual multi-joint robot arms handling an object with both of the arms in accordance with input parameters governing plural respective behaviors to be exhibited by the robot in respective behavior spaces simultaneously. A move-squeeze decomposition processor computes actual move and squeeze decomposition forces based upon current robot force sensor outputs. A compliant motion processor transforms plural object position perturbations of the plural behaviors from the respective behavior spaces to a common space and computes a relative transformation to a behavior-commanded object position in accordance with the object position perturbations of the plural behaviors. A kinematics processor updates a transformation to a current commanded object position based upon the relative transformation to the behavior-commanded object position. A multiple arm squeeze control processor computes from appropriate squeeze force input parameters and from actual squeeze forces for each of the arms, a squeeze control position perturbation for each of the arms, to provide squeeze control. An inverse kinematics processor computes from the commanded object position transformation and from the squeeze control position perturbation, new robot joint angles, and controls respective joints of the robot arms in accordance with the new robot joint angles.

  19. Two-arm master/slave manipulator for nuclear facilities

    International Nuclear Information System (INIS)

    Several kinds of one-arm manipulators have been developed for remote maintenance in nuclear facilities to reduce personnel radiation exposure and to keep plant availability as high as possible. In those maintenance tasks, however, there are many that need two arms, e.g., one arm holds the work object and the other arm cuts it with a plasma torch. To answer this need, a dexterous two-arm master/slave manipulator has been developed based on the technology for one-arm manipulators. A prototype two-arm/slave manipulator is shown. The specifications for master and slave manipulators are listed. The prototype two-arm manipulator is undergoing laboratory performance tests. Preliminary results showed the maximum static operating forces were 0.4 N for the all-direct drive (DD)-type arm and 1.1 N for the semi-DD type. The payload for each arm of the slave manipulator was confirmed as 10 kgf, using mock pieces. The decommissioning tasks of cutting pipes and steel plates were successfully carried out

  20. Build-up forces at Military Institute of Medical Radiology and Oncology for emergency medical response to some eventualities of radiological accidents - some suggestions

    International Nuclear Information System (INIS)

    Nowadays, the use of various nuclear sources in some fields of the life has brought many practical advantages in general; especially in the next several years, our country will begin construction of the first nuclear plant. However, if there were user carelessness or objective disadvantageous factors (earthquake, tsunami, etc.), that disadvantages could lead to a radiation accident or nuclear accident which causes damages not only for economy but also for public health. Therefore, the emergency response to radiation accident, especially the emergency medical response that has a great important position. To satisfy this real demand, in 1996, Vietnam Ministry of Defence made the decision to establish Center for Nuclear Medicine and Radiation Protecting (now becomes Military Institute of Medical Radiology and Oncology) with the main missions are research, applying radiation protecting methods and organizing treatments to radiation injured victims. To fulfill above main missions, with the help of Vietnam Atomic Energy Institute (VAEI), Vietnam Agency for Radiation and Nuclear Safety (VARANS), the doctors and staffs of our Institute have been participated in the international training courses and workshops that organized in Vietnam or in regional countries about emergency medical response to radiation accidents, they get valuable information, knowledge and documents from these courses and workshops. Depending on the principles of radiation emergency medical response to nuclear/ radiation accidents that International Atomic Energy Agency (IAEA) guided, and with the experience learned from other countries in Asia region, our Institute have been gradually improving on organization and curing processes for the radiation victims and also setting the preparedness for emergency medical response to radiation accidents if maybe they could occur.

    2015-10-01

    The Atmospheric Radiation Measurement (ARM) Program was created in 1989 with funding from the U.S. Department of Energy (DOE) to develop several highly instrumented ground stations to study cloud formation processes and their influence on radiative transfer. In 2003, the ARM Program became a national scientific user facility, known as the ARM Climate Research Facility. This scientific infrastructure provides for fixed sites, mobile facilities, an aerial facility, and a data archive available for use by scientists worldwide through the ARM Climate Research Facility—a scientific user facility. The ARM Climate Research Facility currently operates more than 300 instrument systems that provide ground-based observations of the atmospheric column. To keep ARM at the forefront of climate observations, the ARM infrastructure depends heavily on instrument scientists and engineers, also known as lead mentors. Lead mentors must have an excellent understanding of in situ and remote-sensing instrumentation theory and operation and have comprehensive knowledge of critical scale-dependent atmospheric processes. They must also possess the technical and analytical skills to develop new data retrievals that provide innovative approaches for creating research-quality data sets. The ARM Climate Research Facility is seeking the best overall qualified candidate who can fulfill lead mentor requirements in a timely manner.

  5. Hearing Protection Evaluation for the Combat Arms Earplug at Idaho National Laboratory

    2007-03-01

    The Idaho National Laboratory (INL) is managed by Battelle Energy Alliance, LLC (BEA) for the Department of Energy. The INL Protective Security Forces (Pro Force) are involved in training exercises that generate impulse noise by small arms fire. Force-on-force (FOF) training exercises that simulate real world scenarios require the Pro Force to engage the opposition force (OPFOR) while maintaining situational awareness through verbal communications. The Combat Arms earplug was studied to determine if it provides adequate hearing protection in accordance with the requirements of MIL-STD-1474C/D. The Combat Arms earplug uses a design that allows continuous noise through a critical orifice while effectively attenuating high-energy impulse noise. The earplug attenuates noise on a non linear scale, as the sound increases the attenuation increases. The INL studied the effectiveness of the Combat Arms earplug with a Bruel & Kjaer (B&K) head and torso simulator used with a selection of small arms to create impulse sound pressures. The Combat Arms earplugs were inserted into the B&K head and torso ears, and small arms were then discharged to generate the impulse noise. The INL analysis of the data indicates that the Combat Arms earplug does provide adequate protection, in accordance with MIL-STD-1474C/D, when used to protect against impulse noise generated by small arms fire using blank ammunition. Impulse noise generated by small arms fire ranged from 135–160 dB range unfiltered un-weighted. The Combat Arms earplug attenuated the sound pressure 10–25 dB depending on the impulse noise pressure. This assessment is consistent with the results of previously published studies on the Combat Arms earplug (see Section 5, “References”). Based upon these result, the INL intends to use the Combat Arms earplug for FOF training exercises.

    Full Text Available Nonspecific activity-related arm pain is characterized by an absence of objective physical findings and symptoms that do not correspond with objective pathophysiology. Arm pain without strict diagnosis is often related to activity, work-related activity in particular, and is often seen in patients with physically demanding work. Psychological factors such as catastrophic thinking, symptoms of depression, and heightened illness concern determine a substantial percentage of the disability associated with puzzling hand and arm pains. Ergonomic modifications can help to control symptoms, but optimal health may require collaborative management incorporating psychosocial and psychological elements of illness.

  12. Documenting the Effects of Armed Conflict on Population Health.

    Science.gov (United States)

    Levy, Barry S; Sidel, Victor W

    2016-01-01

    War and other forms of armed conflict have profound adverse effects on population health. It is important to document these effects to inform the general public and policy makers about the consequences of armed conflict, provide services to meet the needs of affected populations, protect human rights and document violations of international humanitarian law, and help to prevent future armed conflict. Documentation can be accomplished with surveillance, epidemiological surveys, and rapid assessment. Challenges include inadequate or absent data systems, social breakdown, forced migration, reporting biases, and the fog of war. The adverse effects of the Iraq War on population health demonstrate how the effects of armed conflict on population health can be documented. We recommend the establishment of an independent mechanism, operated by the United Nations or a multilateral organization, to investigate and document the effects of armed conflict on population health.

    1989-04-06

    The Strategic Forces Briefing'' is our attempt, accomplished over the past several months, to outline and highlight the more significant strategic force issues that must be addressed in the near future. Some issues are recurrent: the need for an effective modernized Triad and a constant concern for force survivability. Some issues derive from arms control: the Strategic Arms Reduction Talks (SALT) are sufficiently advanced to set broad numerical limits on forces, but not so constraining as to preclude choices among weapon systems and deployment modes. Finally, a new administration faced with serious budgetary problems must strive for the most effective strategic forces limited dollars can buy and support. A review of strategic forces logically begins with consideration of the missions the forces are charged with. We begin the briefing with a short review of targeting policy and implementation within the constraints of available unclassified information. We then review each element of the Triad with sections on SLBMs, ICBMs, and Air-Breathing (bomber and cruise missile) systems. A short section at the end deals with the potential impact of strategic defense on offensive force planning. We consider ABM, ASAT, and air defense; but we do not attempt to address the technical issues of strategic defense per se. The final section gives a brief overview of the tritium supply problem. We conclude with a summary of recommendations that emerge from our review. The results of calculation on the effectiveness of various weapon systems as a function of cost that are presented in the briefing are by Paul Chrzanowski.

    1990-01-01

    The authors present dual-arm system static operational quality measures which quantify the efficiency and capability of a dual-arm system in generating Cartesian velocities and static forces. First, they define and analyze the kinematic interactions between the two arms incurred by the various modes of dual-arm cooperation, such as transport, assembly, and grasping modes of cooperation, and specify the kinematic constraints imposed on individual arms in Cartesian space due to the kinematic interactions. Dual-arm static manipulability is presented. Finally, dual-arm operational quality is scaled by a task-oriented operational quality measure (TOQs) obtained by the comparison between the desired and actual static manipulabilities. TOQs is used in the optimization of dual-arm joint configurations. Simulation results are shown.

    This report first outlines that nuclear installations are subject to illegal intrusions which challenge their safety and security. It outlines that these installations are extremely sensitive and particularly threatened (the energy sector, as a key sector, is submitted to a specific regulation, and threats are potentially serious), that, beyond the terrorist threat and the risk of sabotage, nuclear installations are regularly facing other illegal behaviours (illegal intrusions are a recurrent issue, and drones are emerging as a new kind of threat), that the protection of nuclear installations is carried out by forces dedicated to this mission (a specialised military force for EDF sites, civil forces for the CEA and Areva, the role of the French Air Force to protect airspace), and that recent legal advances must be deepened. The second part outlines that the present legal protection framework in inadequate and incomplete. The French legal regime is presented and some foreign examples are evoked, and the need of creation of a specific penal regime is outlined. The general discussion and the discussion of the bill project articles are reported. A table proposes a comparative overview between the existing arrangement, the bill project text, and the Commission's text

    Armed conflict has raged in Colombia since at least the 1960’s, involving governmental forces, rebel groups, and paramilitary forces. The Uribe government (2002-2010) declared that Colombia was not in a ‘state of armed conflict’ but was rather facing a ‘terrorist threat’. This declaration was done in fear of conferring a political status to the armed groups, and most particularly, in fear that a recognition of armed conflict would open the possibility of endowing the Revolutionary Ar...

  1. The Temporal Structure of Vertical Arm Movements

    Gaveau, Jérémie; Papaxanthis, Charalambos

    2011-01-01

    The present study investigates how the CNS deals with the omnipresent force of gravity during arm motor planning. Previous studies have reported direction-dependent kinematic differences in the vertical plane; notably, acceleration duration was greater during a downward than an upward arm movement. Although the analysis of acceleration and deceleration phases has permitted to explore the integration of gravity force, further investigation is necessary to conclude whether feedforward or feedback control processes are at the origin of this incorporation. We considered that a more detailed analysis of the temporal features of vertical arm movements could provide additional information about gravity force integration into the motor planning. Eight subjects performed single joint vertical arm movements (45° rotation around the shoulder joint) in two opposite directions (upwards and downwards) and at three different speeds (slow, natural and fast). We calculated different parameters of hand acceleration profiles: movement duration (MD), duration to peak acceleration (D PA), duration from peak acceleration to peak velocity (D PA-PV), duration from peak velocity to peak deceleration (D PV-PD), duration from peak deceleration to the movement end (D PD-End), acceleration duration (AD), deceleration duration (DD), peak acceleration (PA), peak velocity (PV), and peak deceleration (PD). While movement durations and amplitudes were similar for upward and downward movements, the temporal structure of acceleration profiles differed between the two directions. More specifically, subjects performed upward movements faster than downward movements; these direction-dependent asymmetries appeared early in the movement (i.e., before PA) and lasted until the moment of PD. Additionally, PA and PV were greater for upward than downward movements. Movement speed also changed the temporal structure of acceleration profiles. The effect of speed and direction on the form of acceleration

    This history of the events, forces, and factors that have brought the world to the brink of nuclear holocaust probes two basic questions: what factors perpetuate the nuclear arms race and why is it so difficult to end. Starting with the opening days of World War II, this study traces the escalating arms race up to the present and notes that, while nuclear arsenals continue to grow, nuclear arms treaties are on the verge of collapse.

  15. Optimized electrostatic inchworm motors using a flexible driving arm

    International Nuclear Information System (INIS)

    A new motor architecture that uses in-plane electrostatic gap-closing actuators along with a flexible driving arm mechanism to improve motor force density is introduced, optimized, manufactured, and tested. This motor operates similarly to other inchworm-based microactuators by accumulating small displacements from the actuators into much larger displacements in the motor. Using an analytical model of the inchworm motor based on the static force equilibrium condition, optimizations of a full motor design were performed to maximize motor force density. In addition, force losses from supporting flexures were included to calculate the theoretical motor efficiency for different motor designs. This force density optimization analysis of the gap-closing actuators and supporting motor structures provided the basis for designing and manufacturing inchworm motors with flexible driving arms and gap-closing actuators. The motor required only a single-mask fabrication and demonstrated robust performance, a maximum speed of 4.8 mm s−1, and a maximum force on the shuttle of 1.88 mN at 110 V which corresponds to area force density of 1.38 mN mm−2. In addition, instead of estimating motor force based on drawn or measured dimensions which often overestimates force, the demonstrated maximum motor force was measured using calibrated springs. The efficiency of the manufactured motor was measured at 8.75% using capacitance measurements and useful work output. (paper)

  1. Ultrasound power measurements of HITU transducer with a more stable radiation force balance

    International Nuclear Information System (INIS)

    A new radiation force balance (RFB) system was established at Turkish National Metrology Institute (UME) Ultrasonics Laboratory for High intensity therapeutic ultrasound (HITU) power measurements. The new system is highly stable at high power levels up to 500 Watts. The measurement system consists of a Plexiglas cylindrical balance arm, target mounting scale disks, conical reflecting and absorbing targets, adjustment nuts, and a hanging wire. Both of the two sides of balance were mounted similar size and weight targets. The equilibrium of the balance arm can be adjusted with nuts on screws located at both sides of the balance arm. Transducer was mounted to bottom of water tank. Absorbers in the bottom and the near walls of the tank were used for reflecting target case. Ultrasound power was applied to one scale of the balance where the reflecting/absorbing target was mounted and corresponding force was measured on the other scale of balance where was connected to a balance with a thin wire while the thin rest standing on a support. Ultrasound power of two HITU transducers at frequencies 0.93 MHz, 1.1 MHz and 3.3 MHz were measured with conventional and new system, the values were compared and uncertainty components were assessed in this paper.

    The island of Gotland has a large potential for wind power production. An existing weather radar system, however, causes extensive restrictions for further development of wind power on Gotland. In a joint project during 2011 the County Administration Board of Gotland, the Municipality of Gotland and the Swedish Armed Forces have explored ways to overcome the existing conflicts. The project has been sponsored by the Swedish Energy Agency. Through the collaboration, the participants have gained a better understanding of various aspects of the conflicting interests. Studies have been carried out with the prospect to modelling alternative solutions to reduce the conflicts. The study regarding the radar system has been carried out by the Swedish Meteorological and Hydrological Inst.. This report present some practical solutions to avoid conflict in most of areas which are planned for wind power by the municipality. It is suggested that a complimentary radar can be built. A number of alternative localizations for the complimentary radar have been suggested and the potential effects for wind power production estimated. Costs for the suggested solutions have been calculated.

  4. Limitation and reduction of conventional arms

    International Nuclear Information System (INIS)

    We are living at a time when war between East and West---not only nuclear but also conventional war--- is totally senseless. It cannot solve any problem---political, economic, or other. From the military point of view, war between East and West is madness. Calculations show that after 20 days of conventional warfare Europe could become another Hiroshima. Therefore we must work out forms of long-term cooperation. Before it is too late, we must radically reduce our military potentials and rethink our military doctrines. The reduction by 500,000 men is for the USSR no simple solution. But that step may become a model for further actions by East and West. The West's proposal that armed forces should be reduced to the level of 95 percent of NATO's armed forces is not a solution. Both sides---the Warsaw Treaty Organization and NATO---must be deprived of the capacity to launch a sudden attack; they must be deprived of their attack potential. The USSR initiative shows the true way toward that goal. What is happening in connection with our decision is not always correctly interpreted in the West, and so I should like to draw attention to some distinctive features of the Soviet armed forces reductions and, first of all, their scale (equivalent to the Bundeswehr of the Federal Republic of Germany). With respect to Europe, Soviet troops are to be reduced in the German Democratic Republic, Czechoslovakia, Hungary, Poland, and the European part of the Soviet Union---a total of 240,000 men, 10,000 tanks, 9,500 artillery systems, and 800 combat aircraft

  5. Investigation of Calibrating Force Transducer Using Sinusoidal Force

    International Nuclear Information System (INIS)

    Sinusoidal force calibration method was studied several years before at Physikalisch-Technische Bundesanstalt (PTB). A similar dynamic force calibration system is developed at Changcheng Institute of Metrology and Measurement (CIMM). It uses electro-dynamic shakers to generate dynamic force in the range from 1 N to 20 kN, and heterodyne laser interferometers are used for acceleration measurement. The force transducer to be calibrated is mounted on the shaker, and a mass block is screwed on the top of force transducer, the sinusoidal forces realized by accelerated load masses are traceable to acceleration and mass according to the force definition. The methods of determining Spatial-dependent acceleration on mass block and measuring the end mass of force transducer in dynamic force calibration are discussed in this paper.

  6. Supporting the President's Arms Control and Nonproliferation Agenda: Transparency and Verification for Nuclear Arms Reductions

    International Nuclear Information System (INIS)

    The President's arms control and nonproliferation agenda is still evolving and the details of initiatives supporting it remain undefined. This means that DOE, NNSA, NA-20, NA-24 and the national laboratories can help define the agenda, and the policies and the initiatives to support it. This will require effective internal and interagency coordination. The arms control and nonproliferation agenda is broad and includes the path-breaking goal of creating conditions for the elimination of nuclear weapons. Responsibility for various elements of the agenda will be widely scattered across the interagency. Therefore an interagency mapping exercise should be performed to identify the key points of engagement within NNSA and other agencies for creating effective policy coordination mechanisms. These can include informal networks, working groups, coordinating committees, interagency task forces, etc. It will be important for NA-20 and NA-24 to get a seat at the table and a functional role in many of these coordinating bodies. The arms control and nonproliferation agenda comprises both mature and developing policy initiatives. The more mature elements such as CTBT ratification and a follow-on strategic nuclear arms treaty with Russia have defined milestones. However, recent press reports indicate that even the START follow-on strategic arms pact that is planned to be complete by the end of 2009 may take significantly longer and be more expansive in scope. The Russians called for proposals to count non-deployed as well as deployed warheads. Other elements of the agenda such as FMCT, future bilateral nuclear arms reductions following a START follow-on treaty, nuclear posture changes, preparations for an international nuclear security summit, strengthened international safeguards and multilateral verification are in much earlier stages of development. For this reason any survey of arms control capabilities within the USG should be structured to address potential needs across the

According to the geometric relationship and law of conversation of momentum, the Lagrange equation of the second kind is utilized to model the dynamic function of the flexible arm space robot incorporating the assumed modes method. By using this model, a neural network L-two-gain robust control scheme with i-two-gain disturbance attenuation is proposed to dominate the base attitude and the joint angle of manipulator to track desired trajectories synchronously in joint space on condition that system parameters are unknown.

  12. Can a small-changes approach help address the obesity epidemic? A report of the Joint Task Force of the American Society for Nutrition, Institute of Food Technologists, and International Food Information Council.

    Science.gov (United States)

    Hill, James O

    2009-02-01

    The continued rise in obesity rates in most countries suggests that current programs and initiatives designed to combat obesity have not been successful in reversing the obesity epidemic. Obesity rates are increasing because of a gradual weight gain in most populations. There has been little long-term success in treating established obesity through lifestyle change, perhaps because of the large permanent changes in diet and physical activity required to keep weight off. An alternative strategy to address the obesity epidemic involves not focusing on weight loss but promoting small changes in diet and physical activity to initially prevent further weight gain. With the use of this strategy, obesity rates could first be stabilized in most populations and then, over time, decrease gradually. Supporting data show that small reductions in conscious energy intake and increases in physical activity can reduce excessive weight gain. The opportunity exists to use the small-changes approach to bring different stakeholders together to create a national initiative to address the global epidemic of obesity. The Joint Task Force of the American Society for Nutrition, Institute of Food Technologists, and International Food Information Council believe that a small-changes framework, aimed at helping people make conscious small changes in lifestyle behaviors, in combination with efforts by the private sector to gradually "ratchet down" some of the environmental factors that have contributed to excessive energy intake and the declining rates of physical activity, can be successful in reducing obesity rates. Such an initiative would benefit from the support of educational and social marketing campaigns developed with governmental input and support. PMID:19088151

    Lauder, M A; Dabnichki, P

    2005-10-01

    The purpose of this study was to investigate the validity of hydrodynamic force estimation in swimming as calculated by the quasi-static approach. To achieve this a full-scale mechanical arm was developed, built and tested. The mechanical arm, covered with a prosthetic shell and driven at the shoulder was used to simulate a single plane underwater rotation at four elbow configurations. A computer program controlled the shoulder movement to achieve a replicable angular velocity profile for each arm movement. A strain gauge system was used to directly measure the generated arm torque. Repeated trials were conducted at fixed elbow angles of 110 degrees, 135 degrees, 160 degrees and 180 degrees. All trials were filmed using a three-dimensional underwater set-up. Each trial was digitised at 25 Hz and the hydrodynamic drag force profile of the hand calculated using the quasi-static procedure. From these data, the estimated shoulder torque was calculated and compared to the direct measurement of shoulder torque from the mechanical arm. The results showed that the arm produced a repeatable movement through the water. The shoulder torque profiles using the direct measure (the arm) and the indirect measures (quasi-static approach) differed considerably. The quasi-static approach appears not to accurately reflect the hydrodynamic force profile generated by the arm movement in swimming. Furthermore, it seems that the swimmer's hand contribution is overstated in up to date studies. It is essential that the propulsive mechanisms in swimming be further investigated if factors underpinning an optimal technique are to be established. PMID:16045915

    A kind of new obstacle space expression is proposed in this paper, in which a virtual force field (VFF) is built. Using the torque and joint optimization acted by the virtual force field on the anthropomorphic weld arm, the real-time selection of a redundant join (R-joint) is done and its equivalent virtual torque is obtained, thus the redundant joint can be controlled with whose force feedback. An inverse kinematics solution of a 6-DOF robot is applied to other six joints of the arm. Simulation experiments indicate the new inverse kinematics solution has perfect collision avoidance effect, and it is well simplified. Therefore, it can be applied to a welding task in complex operation space.

    We consider a generalization of stochastic bandits where the set of arms, $\\cX$, is allowed to be a generic measurable space and the mean-payoff function is "locally Lipschitz" with respect to a dissimilarity function that is known to the decision maker. Under this condition we construct an arm selection policy, called HOO hierarchical optimistic optimization), with improved regret bounds compared to previous results for a large class of problems. In particular, our results imply that if $\\cX$ is the unit hypercube in a Euclidean space and the mean-payoff function has a finite number of global maxima around which the behavior of the function is locally H\\"older continuous with a known exponent, then the expected of HOO regret is bounded up to a logarithmic factor by $\\sqrt{n}$, i.e., the rate of growth of the regret is independent of the dimension of the space. We also prove the minimax optimality of our algorithm when the dissimilarity is a metric.

    In this book, a modern unified theory of dispersion forces on atoms and bodies is presented which covers a broad range of advanced aspects and scenarios. Macroscopic quantum electrodynamics is shown to provide a powerful framework for dispersion forces which allows for discussing general properties like their non-additivity and the relation between microscopic and macroscopic interactions. It is demonstrated how the general results can be used to obtain dispersion forces on atoms in the presence of bodies of various shapes and materials. Starting with a brief recapitulation of volume I, this volume II deals especially with bodies of irregular shapes, universal scaling laws, dynamical forces on excited atoms, enhanced forces in cavity quantum electrodynamics, non-equilibrium forces in thermal environments and quantum friction. The book gives both the specialist and those new to the field a thorough overview over recent results in the field. It provides a toolbox for studying dispersion forces in various contex...

    Kim, Yongchul; Youm, Youngil; Bae, Hanil; Choi, Hyeonki

    Safety of the occupant during the crash is very essential design element. Many researches have been investigated in reducing the fatal injury of occupant. They are focusing on the development of a dummy in order to obtain the real human-like motion. However, they have not considered the arm resist motion during the car accident. In this study, we would like to suggest the importance of the reactive force of the arm in a car crash. The influences of reactive force acting on the human upper extremity were investigated using the impedance experimental method with lumped mass model of hand system and a Hybrid III dummy with human-like arm. Impedance parameters (e.g. inertia, spring constant and damping coefficient) of the elbow joint in maximum activation level were measured by free oscillation test using single axis robot. The results showed that without seat belt, the reactive force of human arm reduced the head, chest, and femur injury, and the flexion moment of the neck is higher than that of the conventional dummy.

    U.S. service members are at risk of malaria when they are assigned to endemic areas (e.g., Korea), participate in operations in endemic areas (e.g., Afghanistan, Africa) and visit malarious areas during personal travel. In 2011, 124 service members were reported with malaria. Nearly three-fourths of cases were presumably acquired in Afghanistan (n=91) and one-fifth were considered acquired in Africa (n=24). One-quarter of cases were caused by P. vivax and one-fifth by P. falciparum (including 6 Afghanistan-acquired infections); most cases were reported as "unspecified" malaria. Malaria was diagnosed/reported from 51 different medical facilities in the United States, Afghanistan, Kyrgyzstan, Iraq, Germany and Korea. Providers of care to military members should be knowledgeable regarding and vigilant for clinical presentations of malaria outside of endemic areas. PMID:22309389

  9. Nuclear arms cleanup

    International Nuclear Information System (INIS)

    The Soviet Union's demise five years ago brought an end to the Cold War, the 45-year arms race between the Soviet superpower and the United States. The euphoria that greeted the end of this bloodless conflict has dampened somewhat, however, as U.S. officials and their counterparts in the former Soviet republics come to grips with its legacy: thousands of highly toxic and politically destabilizing nuclear weapons. With no more perceived need for much of their vast arsenals, the governments have agreed to dismantle large numbers of nuclear warheads. But the agencies involved in this task face a daunting technical and political problem: what to do with the thousands of tons of plutonium and uranium that are the main ingredients of nuclear weapons

  11. Treatment of Glioma Using neuroArm Surgical System

    Science.gov (United States)

    2016-01-01

    The use of robotic technology in the surgical treatment of brain tumour promises increased precision and accuracy in the performance of surgery. Robotic manipulators may allow superior access to narrow surgical corridors compared to freehand or conventional neurosurgery. This paper reports values and ranges of tool-tissue interaction forces during the performance of glioma surgery using an MR compatible, image-guided neurosurgical robot called neuroArm. The system, capable of microsurgery and stereotaxy, was used in the surgical resection of glioma in seven cases. neuroArm is equipped with force sensors at the end-effector allowing quantification of tool-tissue interaction forces and transmits force of dissection to the surgeon sited at a remote workstation that includes a haptic interface. Interaction forces between the tool tips and the brain tissue were measured for each procedure, and the peak forces were quantified. Results showed maximum and minimum peak force values of 2.89 N (anaplastic astrocytoma, WHO grade III) and 0.50 N (anaplastic oligodendroglioma, WHO grade III), respectively, with the mean of peak forces varying from case to case, depending on type of the glioma. Mean values of the peak forces varied in range of 1.27 N (anaplastic astrocytoma, WHO grade III) to 1.89 N (glioblastoma with oligodendroglial component, WHO grade IV). In some cases, ANOVA test failed to reject the null hypothesis of equality in means of the peak forces measured. However, we could not find a relationship between forces exerted to the pathological tissue and its size, type, or location. PMID:27314044

    Full Text Available

    Armed conflict has raged in Colombia since at least the 1960’s, involving governmental forces, rebel groups, and paramilitary forces. The Uribe government (2002-2010 declared that Colombia was not in a ‘state of armed conflict’ but was rather facing a ‘terrorist threat’. This declaration was done in fear of conferring a political status to the armed groups, and most particularly, in fear that a recognition of armed conflict would open the possibility of endowing the Revolutionary Armed Forces of Colombia (FARC with a ‘belligerency status’. From a legal point of view, the government’s fears were unfounded, since contemporary international humanitarian law does not require a formal for a situation to qualify as armed conflict. During the Uribe administration, efforts were made by the Ministry of Defense to identify operational rules of engagement with precision, violations of international humanitarian law were publicly denounced, and the apex courts adjudicated on issues of international humanitarian law. This seemingly paradoxical situation illustrates the importance of the objective definition of armed conflict, which has been a defining characteristic of international humanitarian law since 1949.

     

  13. Multijoint arm stiffness during movements following stroke: implications for robot therapy

    Science.gov (United States)

    Piovesan, D.; Casadio, M.; Mussa-Ivaldi, F. A.; Morasso, P.G

    2015-01-01

    Impaired arm movements in stroke appear as a set of stereotypical kinematic patterns, characterized by abnormal joint coupling, which have a direct consequence on arm mechanics and can be quantified by the net arm stiffness at the hand. The current available measures of arm stiffness during functional tasks have limited clinical use, since they require several repetitions of the same test movement in many directions. Such procedure is difficult to obtain in stroke survivors who have lower fatigue threshold and increased variability compared to unimpaired individuals. The present study proposes a novel, fast quantitative measure of arm stiffness during movements by means of a Time-Frequency technique and the use of a reassigned spectrogram, applied on a trial-by-trial basis with a single perturbation. We tested the technique feasibility during robot mediated therapy, where a robot helped stroke survivors to regain arm mobility by providing assistive forces during a hitting task to 13 targets covering the entire reachable workspace. The endpoint stiffness of the paretic arm was estimated at the end of each hitting movements by suddenly switching of the assistive forces and observing the ensuing recoil movements. In addition, we considered how assistive forces influence stiffness. This method will provide therapists with improved tools to target the treatment to the individual’s specific impairment and to verify the effects of the proposed exercises. PMID:22275576

  15. EU Armed Forces’ Use of Social Media in Areas of Deployment

    Directory of Open Access Journals (Sweden)

    2016-02-01

    Full Text Available The advent of social media can be seen both as a risk and an opportunity by armed forces. Previous research has primarily examined whether or not the use of social media endangers or strengthens armed forces’ strategic narrative. We examine armed forces’ perceptions of risks and opportunities on a broad basis, with a particular focus on areas of deployment. The article is based on a survey of perceptions of social media amongst the armed forces of EU member states, thus adding to previous research through its comparative perspective. Whereas previous research has mainly focused on larger powers, such as the US and the UK, this article includes the views of the armed forces of 26 EU states, including several smaller nations. In analyzing the results we asked whether or not risk and opportunity perceptions were related to national ICT maturity and the existence of a social media strategy. The analysis shows that perceptions of opportunities outweigh perceptions of risks, with marketing and two-way communication as the two most prominent opportunities offered by the use of social media. Also, armed forces in countries with a moderate to high ICT maturity emphasize social media as a good way for marketing purposes.

  16. Strong Force

    CERN Multimedia

    Without the strong force, there could be no life. The carbon in living matter is synthesised in stars via the strong force. Lighter atomic nuclei become bound together in a process called nuclear fusion. A minor change in this interaction would make life impossible. As its name suggests, the strong force is the most powerful of the 4 forces, yet its sphere of influence is limited to within the atomic nucleus. Indeed it is the strong force that holds together the quarks inside the positively charged protons. Without this glue, the quarks would fly apart repulsed by electromagnetism. In fact, it is impossible to separate 2 quarks : so much energy is needed, that a second pair of quarks is produced. Text for the interactive: Can you pull apart the quarks inside a proton?

    The end of the cold war also ended the focus on the bilateral approach to arms control and disarmament. Key concepts of security needed to be revisited, along with their implications for the disarmament and arms control agenda. Though there is currently a unipolar global security environment, there remain important tasks on the multilateral arms control agenda. The major task is that of reducing and eliminating weapons of mass destruction, especially nuclear weapons. The author contends that maintaining reliance on the nuclear-weapons option makes little sense in a time when the major Powers are strengthening their partnerships in economics, trade, peacemaking and building.

    In the last ten years, since the break-up of the Soviet Union, remarkable progress in arms control and disarmament has occurred. The Nuclear Non-Proliferation Treaty (NPT), the completion of the Comprehensive Test Ban Treaty (CTBT), and the Chemical Weapons Treaty (CWC) are indicative of the great strides made in the non- proliferation arena. Simultaneously, the Intermediate Nuclear Forces Treaty (INF), the Conventional Forces Treaty in Europe (CFE), and the Strategic Arms Reduction Treaties (START), all associated with US-Soviet Union (now Russia) relations have assisted in redefining European relations and the security landscape. Finally, it now appears that progress is in the offing in developing enhanced compliance measures for the Biological and Toxin Weapons Convention (BTWC). In sum, all of these achievements have set the stage for the next round of arms control activities, which may lead to a much broader, and perhaps more diffused multilateral agenda. In this new and somewhat unpredictable international setting, arms control and disarmament issues will require solutions that are both more creative and innovative than heretofore.

    Limited knowledge exists about the forces acting on mitral valve annuloplasty repair devices. The aim of this study was to develop a new mitral annular force transducer to measure the forces acting on clinically used mitral valve annuloplasty devices. The design of an X-shaped transducer in the present study was optimized for simultaneous in- and out-of-plane force measurements. Each arm was mounted with strain gauges on four circumferential elements to measure out-of-plane forces, and the central parts of the X-arms were mounted with two strain gauges to measure in-plane forces. A dedicated calibration setup was developed to calibrate isolated forces with tension and compression for in- and out-of-plane measurements. With this setup, it was possible with linear equations to isolate and distinguish measured forces between the two planes and minimize transducer arm crosstalk. An in-vitro test was performed to verify the crosstalk elimination method and the assumptions behind it. The force transducer was implanted and evaluated in an 80kg porcine in-vivo model. Following crosstalk elimination, in-plane systolic force accumulation was found to be in average 4.0±0.1N and the out-of-plane annular segments experienced an average force of 1.4±0.4N. Directions of the systolic out-of-plane forces indicated movements towards a saddle shaped annulus, and the transducer was able to measure independent directional forces in individual annular segments. Further measurements with the new transducer coupled with clinical annuloplasty rings will provide a detailed insight into the biomechanical dynamics of these devices. PMID:26903412

  5. Weak Force

    CERN Multimedia

    Without the weak force, the sun wouldn't shine. The weak force causes beta decay, a form of radioactivity that triggers nuclear fusion in the heart of the sun. The weak force is unlike other forces: it is characterised by disintegration. In beta decay, a down quark transforms into an up quark and an electron is emitted. Some materials are more radioactive than others because the delicate balance between the strong force and the weak force varies depending on the number of particles in the atomic nucleus. We live in the midst of a natural radioactive background that varies from region to region. For example, in Cornwall where there is a lot of granite, levels of background radiation are much higher than in the Geneva region. Text for the interactive: Move the Geiger counter to find out which samples are radioactive - you may be surprised. It is the weak force that is responsible for the Beta radioactivity here.

    Data and metadata standards promote the consistent recording of information and are necessary to ensure the stability and high quality of Atmospheric Radiation Measurement (ARM) Climate Research Facility data products for scientific users. Standards also enable automated routines to be developed to examine data, which leads to more efficient operations and assessment of data quality. Although ARM Infrastructure agrees on the utility of data and metadata standards, there is significant confusion over the existing standards and the process for allowing the release of new data products with exceptions to the standards. The ARM Standards Policy Committee was initiated in March 2012 to develop a set of policies and best practices for ARM data and metadata standards.

    Full Text Available The relative contribution of arm stroke and leg kicking to maximal fully tethered front crawl swimming performance remains to be solved. Twenty-three national level young swimmers (12 male and 11 female randomly performed 3 bouts of 30 s fully tethered swimming (using the whole body, only the arm stroke, and only the leg kicking. A load-cell system permitted the continuous measurement of the exerted forces, and swimming velocity was calculated from the time taken to complete a 50 m front crawl swim. As expected, with no restrictions swimmers were able to exert higher forces than that using only their arm stroke or leg kicking. Estimated relative contributions of arm stroke and leg kicking were 70.3% versus 29.7% for males and 66.6% versus 33.4% for females, with 15.6% and 13.1% force deficits, respectively. To obtain higher velocities, male swimmers are highly dependent on the maximum forces they can exert with the arm stroke (r=0.77, P<0.01, whereas female swimmers swimming velocity is more related to whole-body mean forces (r=0.81, P<0.01. The obtained results point that leg kicking plays an important role over short duration high intensity bouts and that the used methodology may be useful to identify strength and/or coordination flaws.

    Postural sway during quiet stance is attenuated by actively maintained contact of the index finger with a stationary surface, even if the level of applied force (proprioceptive information about the hand and arm can serve as an active sensor of body position relative to the point of contact. A geometric analysis of the relationship between hand and torso displacement during body sway led to the prediction that arm and hand proprioceptive and finger somatosensory information about body sway would be maximized with finger contact in the plane of body sway. Therefore, the most postural stabilization should be possible with such contact. To test this analysis, subjects touched a laterally versus anteriorly placed surface while in each of two stances: the heel-to-toe tandem Romberg stance that reduces medial-lateral stability and the heel-to-heel, toes-outward, knees-bent, "duck stance" that reduces fore-aft stability. Postural sway was always least with finger contact in the unstable plane: for the tandem stance, lateral fingertip contact was significantly more effective than frontal contact, and, for the duck stance, frontal contact was more effective than lateral fingertip contact. Force changes at the fingertip led changes in center of pressure of the feet by approximately 250 ms for both fingertip contact locations for both test stances. These results support the geometric analysis, which showed that 1) arm joint angles change by the largest amount when fingertip contact is maintained in the plane of greatest sway, and 2) the somatosensory cues at the fingertip provide both direction and amplitude information about sway when the finger is contacting a surface in the unstable plane.

    2012-08-01

    Full Text Available Abstract Background This study investigated the relationship between dental occlusion and arm strength; in particular, the imbalance in the jaw can cause loss in arm strength phenomenon. One of the goals of this study was to record the maximum forces that the subjects can resist against the pull-down force on their hands while biting a spacer of adjustable height on the right or left side of the jaw. Then EMG measurement was used to determine the EMG-Force relationship of the jaw, neck and arms muscles. This gave us useful insights on the arms strength loss due to the biomechanical effects of the imbalance in the jaw mechanism. Methods In this study to determine the effects of the imbalance in the jaw to the strength of the arms, we conducted experiments with a pool of 20 healthy subjects of both genders. The subjects were asked to resist a pull down force applied on the contralateral arm while biting on a firm spacer using one side of the jaw. Four different muscles – masseter muscles, deltoid muscles, bicep muscles and trapezoid muscles – were involved. Integrated EMG (iEMG and Higuchi fractal dimension (HFD were used to analyze the EMG signals. Results The results showed that (1 Imbalance in the jaw causes loss of arm strength contra-laterally; (2 The loss is approximately a linear function of the height of the spacers. Moreover, the iEMG showed the intensity of muscle activities decreased when the degrees of jaw imbalance increased (spacer thickness increased. In addition, the tendency of Higuchi fractal dimension decreased for all muscles. Conclusions This finding indicates that muscle fatigue and the decrease in muscle contraction level leads to the loss of arm strength.

  1. Institutions and Modernity

    Directory of Open Access Journals (Sweden)

    Witold Morawski

    2013-09-01

    Full Text Available Purpose: Modernity consists of many confl icting aspects: It brings many empty promises, yet has resulted in new institutions that create bridges between the values and interests of millions of people who seek freedom, prosperity, quality of life, strengthened democracy and social justice. In this paper I attempt to a gain and loss account against modernity, because institutional rules are not only conducive to cooperative interactions, but to hostile interactions as well. People are not always guided by moral commitment, but rather more often driven by cold calculation or coercion.Methodology: Modernity has at least three defi nitions. The fi rst defi nition is based on ideas that took over the imagination of the era. The second defi nition is based on an analysis of the behavior of people who respond to reason as well as emotion and believe that they act more rationally than their ancestors or the traditional “others”. The third defi nition is the one closest to my heart, consisting of the use of institutional categories. Institutions offer practical ways of connecting ideas and people. The challenge for them is the result of deepening local and national interdependencies, but increasingly often also regional (e.g. European and global. Interdependencies are the result of the scientifi c and technological revolution, global markets, global governance mechanisms, the emergence of new social forces and cultural confl icts (against the background of reconciling identity and differences.Conclusions: The most important task is to identify the mechanisms of complex systems so that people know how to act under conditions of uncertainty, risk and crisis. Hence, the expectations toward institutions often exceed their abilities. Even though new institutions are being created and old ones are being fixed, we are witnessing and participating in, institutional paralysis and the decay (e.g. corruption. In this situation, it is imperative not only to

    Institutions formalize the intuitive notion of logical system, including both syntax and semantics. A surprising number of different notions of morphisim have been suggested for forming categories with institutions as objects, and a surprising variety of names have been proposed for them. One goal of this paper is to suggest a terminology that is both uniform and informative to replace the current rather chaotic nomenclature. Another goal is to investigate the properties and interrelations of these notions. Following brief expositions of indexed categories, twisted relations, and Kan extensions, we demonstrate and then exploit the duality between institution morphisms in the original sense of Goguen and Burstall, and the 'plain maps' of Meseguer, obtaining simple uniform proofs of completeness and cocompleteness for both resulting categories; because of this duality, we prefer the name 'comorphism' over 'plain map.' We next consider 'theoroidal' morphisms and comorphisims, which generalize signatures to theories, finding that the 'maps' of Meseguer are theoroidal comorphisms, while theoroidal morphisms are a new concept. We then introduce 'forward' and 'semi-natural' morphisms, and appendices discuss institutions for hidden algebra, universal algebra, partial equational logic, and a variant of order sorted algebra supporting partiality.

    Wilcox, Brian; Tso, Kam; Litwin, Todd; Hayati, Samad; Bon, Bruce

    1989-01-01

    Dual-arm satellite grappling involves the integration of technologies developed in the Sensing and Perception (S&P) Subsystem for object acquisition and tracking, and the Manipulator Control and Mechanization (MCM) Subsystem for dual-arm control. S&P acquires and tracks the position, orientation, velocity, and angular velocity of a slowly spinning satellite, and sends tracking data to the MCM subsystem. MCM grapples the satellite and brings it to rest, controlling the arms so that no excessive forces or torques are exerted on the satellite or arms. A 350-pound satellite mockup which can spin freely on a gimbal for several minutes, closely simulating the dynamics of a real satellite is demonstrated. The satellite mockup is fitted with a panel under which may be mounted various elements such as line replacement modules and electrical connectors that will be used to demonstrate servicing tasks once the satellite is docked. The subsystems are housed in three MicroVAX II microcomputers. The hardware of the S&P Subsystem includes CCD cameras, video digitizers, frame buffers, IMFEX (a custom pipelined video processor), a time-code generator with millisecond precision, and a MicroVAX II computer. Its software is written in Pascal and is based on a locally written vision software library. The hardware of the MCM Subsystem includes PUMA 560 robot arms, Lord force/torque sensors, two MicroVAX II computers, and unimation pneumatic parallel grippers. Its software is written in C, and is based on a robot language called RCCL. The two subsystems are described and test results on the grappling of the satellite mockup with rotational rates of up to 2 rpm are provided.

    2015-11-01

    The National Aeronautics and Space Administration (NASA) is developing a robotic mission to visit a large near-Earth asteroid (NEA), collect a multi-ton boulder from its surface, and redirect it into a stable orbit around the Moon. Once returned to cislunar space in the mid-2020s, astronauts will explore the boulder and return to Earth with samples. This Asteroid Redirect Mission (ARM) is part of NASA’s plan to advance the technologies, capabilities, and spaceflight experience needed for a human mission to the Martian system in the 2030s. Subsequent human and robotic missions to the asteroidal material would also be facilitated by its return to cislunar space. Although ARM is primarily a capability demonstration mission (i.e., technologies and associated operations), there exist significant opportunities to advance our knowledge of small bodies in the synergistic areas of science, planetary defense, asteroidal resources and in-situ resource utilization (ISRU), and capability and technology demonstrations. In order to maximize the knowledge return from the mission, NASA is organizing an ARM Investigation Team, which is being preceded by the Formulation Assessment and Support Team. These teams will be comprised of scientists, technologists, and other qualified and interested individuals to help plan the implementation and execution of ARM. An overview of robotic and crewed segments of ARM, including the mission requirements, NEA targets, and mission operations, will be provided along with a discussion of the potential opportunities associated with the mission.

  10. Torque control in lingual orthodontics with lever arm mechanics: a case report.

    Science.gov (United States)

    Aravind, M; Shivaprakash, G; Ramesh, G C

    2013-01-01

    The aim of this report is to illustrate treatment mechanics for torque control in lingual mechanotherapy using a lever arm and transpalatal arch (TPA) tab system during en masse retraction of anterior teeth. An 18-year-old female with bimaxillary dentoalveolar proclination with crowding was treated with a lever arm-TPA tab system. The retraction tabs bent into the TPA placed across the maxillary second molars were used as anchorage. The retraction force on the maxillary anterior teeth was applied using lever arm hooks soldered between the lateral incisors and canines on a lingual mushroom archwire. By applying a retraction force to the lever arm hooks, the maxillary anterior teeth experienced greater palatal root movement as compared to the conventional retraction forces applied at the crown level. The tabs, placed high in the TPA, produced a distal tipping moment on the maxillary second molars, reinforcing their anchorage. The retraction force applied to the long lever arm hooks from the TPA tabs at the level of center of resistance (CRes) of anterior and posterior teeth is advantageous mainly in two aspects. First, it reinforces the anchorage, and second, it favors the palatal root movement of anterior teeth, thus obtaining better control over the torque during en masse retraction. PMID:23646329

    Cultural forces govern a synergistic relationship among information institutions that shapes their roles collectively and individually. Cultural synergy is the combination of perception- and behavior-shaping knowledge within, between, and among groups. Our hyperlinked era makes information-sharing among institutions critically important for scholarship as well as for the advancement of humankind. Information institutions are those that have, or share in, the mission to preserve, conserve, and disseminate information objects and their informative content.

  12. Scanning ARM Cloud Radar Handbook

    Energy Technology Data Exchange (ETDEWEB)

    Widener, K; Bharadwaj, N; Johnson, K

    2012-06-18

    The scanning ARM cloud radar (SACR) is a polarimetric Doppler radar consisting of three different radar designs based on operating frequency. These are designated as follows: (1) X-band SACR (X-SACR); (2) Ka-band SACR (Ka-SACR); and (3) W-band SACR (W-SACR). There are two SACRs on a single pedestal at each site where SACRs are deployed. The selection of the operating frequencies at each deployed site is predominantly determined by atmospheric attenuation at the site. Because RF attenuation increases with atmospheric water vapor content, ARM's Tropical Western Pacific (TWP) sites use the X-/Ka-band frequency pair. The Southern Great Plains (SGP) and North Slope of Alaska (NSA) sites field the Ka-/W-band frequency pair. One ARM Mobile Facility (AMF1) has a Ka/W-SACR and the other (AMF2) has a X/Ka-SACR.

    In this paper, a new approach for a multilayer elastic beam to provide a driving force and driving distance for a MEMS safe and arming system is presented. In particular this is applied where a monolayer elastic beam cannot provide adequate driving force and driving distance at the same time in limited space. Compared with thicker elastic beams, the bilayer elastic beam can provide twice the driving force of a monolayer beam to guarantee the MEMS safe and arming systems work reliably without decreasing the driving distance. In this paper, the theoretical analysis, numerical simulation and experimental verification of the multilayer elastic beam is presented. The numerical simulation and experimental results show that the bilayer elastic provides 1.8–2 times the driving force of a monolayer, and a method that improves driving force without reducing the driving distance.

    We present experimental and numerical results demonstrating the drastic influence of attractive forces on the behaviour of the atomic force microscope when operated in the resonant tapping tip mode in an ambient environment. It is often assumed that tapping is related to repulsive interaction....... In contrast, we find that in general the attractive forces are the most dominant interaction in this mode of operation. We show that attractive forces in combination with the repulsive elastic type of forces cause points of instability in the parameter space constituted by: the cantilever swing amplitude......, the frequency bias point, and the distance between the fixed end of the cantilever and the sample. These points of instability can result in disturbances during image acquisition on hard elastic surfaces. ©1997 American Institute of Physics....

  16. Developments of new force reflecting control schemes and an application to a teleoperation training simulator

    Kim, Won S.

    1992-01-01

    Two schemes of force reflecting control, position-error based force reflection and low-pass-filtered force reflection, both combined with shared compliance control, were developed for dissimilar master-slave arms. These schemes enabled high force reflection gains, which were not possible with a conventional scheme when the slave arm was much stiffer than the master arm. The experimental results with a peg-in-hole task indicated that the newly force reflecting control schemes combined with compliance control resulted in best task performances. As a related application, a simulated force reflection/shared compliance control teleoperation trainer was developed that provided the operator with the feel of kinesthetic force virtual reality.

  18. Supporting the President's Arms Control and Nonproliferation Agenda: Transparency and Verification for Nuclear Arms Reductions

    2009-01-01

    The President's arms control and nonproliferation agenda is still evolving and the details of initiatives supporting it remain undefined. This means that DOE, NNSA, NA-20, NA-24 and the national laboratories can help define the agenda, and the policies and the initiatives to support it. This will require effective internal and interagency coordination. The arms control and nonproliferation agenda is broad and includes the path-breaking goal of creating conditions for the elimination of nuclear weapons. Responsibility for various elements of the agenda will be widely scattered across the interagency. Therefore an interagency mapping exercise should be performed to identify the key points of engagement within NNSA and other agencies for creating effective policy coordination mechanisms. These can include informal networks, working groups, coordinating committees, interagency task forces, etc. It will be important for NA-20 and NA-24 to get a seat at the table and a functional role in many of these coordinating bodies. The arms control and nonproliferation agenda comprises both mature and developing policy initiatives. The more mature elements such as CTBT ratification and a follow-on strategic nuclear arms treaty with Russia have defined milestones. However, recent press reports indicate that even the START follow-on strategic arms pact that is planned to be complete by the end of 2009 may take significantly longer and be more expansive in scope. The Russians called for proposals to count non-deployed as well as deployed warheads. Other elements of the agenda such as FMCT, future bilateral nuclear arms reductions following a START follow-on treaty, nuclear posture changes, preparations for an international nuclear security summit, strengthened international safeguards and multilateral verification are in much earlier stages of development. For this reason any survey of arms control capabilities within the USG should be structured to address potential needs

    From October 1 through September 30, 2016, the Atmospheric Radiation Measurement (ARM) Aerial Facility will deploy the Cessna 206 aircraft over the Southern Great Plains (SGP) site, collecting observations of trace-gas mixing ratios over the ARM’s SGP facility. The aircraft payload includes two Atmospheric Observing Systems, Inc., analyzers for continuous measurements of CO2 and a 12-flask sampler for analysis of carbon cycle gases (CO2, CO, CH4, N2O, 13CO2, 14CO2, carbonyl sulfide, and trace hydrocarbon species, including ethane). The aircraft payload also includes instrumentation for solar/infrared radiation measurements. This research is supported by the U.S. Department of Energy’s ARM Climate Research Facility and Terrestrial Ecosystem Science Program and builds upon previous ARM Airborne Carbon Measurements (ARM-ACME) missions. The goal of these measurements is to improve understanding of 1) the carbon exchange at the SGP site, 2) how CO2 and associated water and energy fluxes influence radiative forcing, convective processes and CO2 concentrations over the SGP site, and 3) how greenhouse gases are transported on continental scales.

  20. Structural Optimization of Slender Robot Arm Based on Sensitivity Analysis

    2012-01-01

    Full Text Available An effective structural optimization method based on a sensitivity analysis is proposed to optimize the variable section of a slender robot arm. The structure mechanism and the operating principle of a polishing robot are introduced firstly, and its stiffness model is established. Then, a design of sensitivity analysis method and a sequential linear programming (SLP strategy are developed. At the beginning of the optimization, the design sensitivity analysis method is applied to select the sensitive design variables which can make the optimized results more efficient and accurate. In addition, it can also be used to determine the scale of moving step which will improve the convergency during the optimization process. The design sensitivities are calculated using the finite difference method. The search for the final optimal structure is performed using the SLP method. Simulation results show that the proposed structure optimization method is effective in enhancing the stiffness of the robot arm regardless of the robot arm suffering either a constant force or variable forces.

  4. Reduction of conventional forces in Europe

    International Nuclear Information System (INIS)

    The reduction of NATO and Warsaw Treaty armed forces and conventional arms in Europe constitutes a key problem of disarmament. Both NATO and the Warsaw Treaty stand for removing the existing asymmetries and imbalances through cuts in armed forces and armaments, above all those that have the capability of surprise attack, or large-scale offensive operations. We feel that prospects now look good for the elaboration of such an accord. To this end, we should proceed to elaborate a first set of agreements right away, while regarding the Vienna negotiations as a continuous process and without wasting time on general discussion, which, as experience shows, may only fossilize our positions. In particular, both sides place top priority on reducing those armaments that may have the capability of surprise attack, or large-scale offensive operations. it is obvious that our attention should be focused above all on those armaments while eliminating imbalances and reducing arms. If we follow this path, i.e., single out the most dangerous types of offensive weapons (for example, attack aircraft, combat helicopters, tanks, artillery, armored personnel carriers, landing-crossing means, etc.), set ceilings on them that would be lower than the currently existing and lowest levels of NATO and the Warsaw Treaty, an agreement could be promptly reached

  8. Testbed model and data assimilation for ARM

    International Nuclear Information System (INIS)

    The objectives of this contract are to further develop and test the ALFA (AER Local Forecast and Assimilation) model originally designed at AER for local weather prediction and apply it to three distinct but related purposes in connection with the Atmospheric Radiation Measurement (ARM) program: (a) to provide a testbed that simulates a global climate model in order to facilitate the development and testing of new cloud parametrizations and radiation models; (b) to assimilate the ARM data continuously at the scale of a climate model, using the adjoint method, thus providing the initial conditions and verification data for testing parameumtions; (c) to study the sensitivity of a radiation scheme to cloud parameters, again using the adjoint method, thus demonstrating the usefulness of the testbed model. The data assimilation will use a variational technique that minimizes the difference between the model results and the observation during the analysis period. The adjoint model is used to compute the gradient of a measure of the model errors with respect to nudging terms that are added to the equations to force the model output closer to the data. The radiation scheme that will be included in the basic ALFA model makes use of a gen two-stream approximation, and is designed for vertically inhonogeneous, multiple-scattering atmospheres. The sensitivity of this model to the definition of cloud parameters will be studied. The adjoint technique will also be used to compute the sensitivities. This project is designed to provide the Science Team members with the appropriate tools and modeling environment for proper testing and tuning of new radiation models and cloud parametrization schemes

  9. Nuclear arms race gearing for speedup

    International Nuclear Information System (INIS)

    To probe the rationale behind the big buildup in US strategic arms that is presaged by the current enhanced R and D effort - and to explore the broader, more long-term role of science and technology in the nuclear arms race - C and EN in recent months spoke with a host of experts both within and outside the defense establishment. It is a topic of incredible complexity, high controversy, and of the highest stakes imaginable - the survival of civilization. This buildup will include over the next decade, apart from the MX, a new, highly accurate, submarine-launched ballistic missile and a fleet of very large submarines to carry it; an air-launched cruise missile; a new long-range bomber; a new intermediate-range missile and a new ground-launched cruise missile, both capable of hitting targets in the Soviet Union from proposed bases in Western Europe; and a new sea-launched cruise missile that can be fired from conventional submarines or other naval vessels. To spokesmen for, and members of, the defense establishment the US buildup is prudent, even minimal. According to them, it is needed to keep the US at least on a par with the growth of Soviet strategic might which was very substantial in the 1970's and which will carry over into the 1980's with further major gains. It also is needed to keep the lid on Soviet expansionism; and it is the best way to prevent a nuclear war. To critics, the proposed buildup is the height of lunacy. According to them, the US strategic arsenal is more than adequate today. And it can continue to serve its only legitimate purpose - to deter nuclear war, no matter how much the Soviets may choose to build up their nuclear forces - with a much-more-modest modernization program

At the outbreak of war in September, 1939, the armed forces of the Union consisted of a Permanent Force of 352 Officers and 5033 men, and an Active Citizen Force of 918 Officers and 12 572 men. Of the Permanent Force, 173 Officers and 1664 men formed the South African Air Force, 47 Officers and 562 men were members of the South African Artillery and 17 Officers and 1 705 men formed the Special Service Battalion, a unit consisting of men who served on a short-service basis for a minimum of one year. The rest were concerned principally in the supply services and in administering the Active Citizen Force. The latter was roughly parallel to the Territorial Army in Britain, since membership, although nominally compulsory, was in effect restricted to volunteers from among the various age groups called up annually for compulsory registration. Members of the Active Citizen Force were enrolled in units, some of which could show a history dating back to the middle of the last century, and were required to perform 1½ to 4 hours of non-continuous training per week, and 15 days of continuous training, in camp, each year.

    Previous literature suggests that learning and memory formation can be influenced by diet and exercise. In the current study, we investigated the combined effects of forced swimming exercise (FSE) and every other day fasting (EODF) on spatial memory formation and on the levels of brain-derived neurotrophic factor (BDNF) in the hippocampus of Wistar male rats. The radial arm water maze (RAWM) paradigm was used to assess changes in learning and memory formation, whereas ELISA assay was used to measure BDNF protein levels. The FSE and/or EODF were simultaneously instituted for 6 weeks. Results show that FSE improved learning, short-term as well as long-term memory formation, and significantly increased BDNF protein in the hippocampus (p0.05). In addition, EODF did not modulate beneficial effect of swimming exercise on cognitive function (p>0.05). Thus exercise enhanced, while EODF did not affect spatial learning and memory formation.

  12. Performance of arm locking in LISA

    For the Laser Interferometer Space Antenna (LISA) to reach its design sensitivity, the coupling of the free-running laser frequency noise to the signal readout must be reduced by more than 14 orders of magnitude. One technique employed to reduce the laser frequency noise will be arm locking, where the laser frequency is locked to the LISA arm length. In this paper we detail an implementation of arm locking. We investigate orbital effects (changing arm lengths and Doppler frequencies), the impact of errors in the Doppler knowledge that can cause pulling of the laser frequency, and the noise limit of arm locking. Laser frequency pulling is examined in two regimes: at lock acquisition and in steady state. The noise performance of arm locking is calculated with the inclusion of the dominant expected noise sources: ultrastable oscillator (clock) noise, spacecraft motion, and shot noise. We find that clock noise and spacecraft motion limit the performance of dual arm locking in the LISA science band. Studying these issues reveals that although dual arm locking [A. Sutton and D. A. Shaddock, Phys. Rev. DPRVDAQ1550-7998 78, 082001 (2008)10.1103/PhysRevD.78.082001] has advantages over single (or common) arm locking in terms of allowing high gain, it has disadvantages in both laser frequency pulling and noise performance. We address this by proposing a modification to the dual arm-locking sensor, a hybrid of common and dual arm-locking sensors. This modified dual arm-locking sensor has the laser frequency pulling characteristics and low-frequency noise coupling of common arm locking, but retains the control system advantages of dual arm locking. We present a detailed design of an arm-locking controller and perform an analysis of the expected performance when used with and without laser prestabilization. We observe that the sensor phase changes beneficially near unity-gain frequencies of the arm-locking controller, allowing a factor of 10 more gain than previously believed

    Full Text Available Cinema is an act of representation and it is based on the construction of reality inspired by experience. In Colombia, cinema has not been the product of a structured industry, but rather the effort of some filmmakers who have found different ways of telling stories about topics that are part of the national experience. The armed conflict in Colombia, understood as the confrontation between government forces and organized outlawed groups, has prevailed for more than fifty years and has been present in art forms ever since. This research examines a sample of Colombian films to establish the different ways the subject of the armed conflict has been represented in Colombian cinema.

  15. Different strategy of hand choice after learning of constant and incremental dynamical perturbation in arm reaching

    Full Text Available In daily life, we encounter situations where we must quickly decide which hand to use for a motor action. Here, we investigated whether the hand chosen for a motor action varied over a short timescale (i.e., hours with changes in arm dynamics. Participants performed a reaching task in which they moved a specified hand to reach a target on a virtual reality display. During the task, a resistive viscous force field was abruptly applied to only the dominant hand. To evaluate changes in hand choice caused by this perturbation, participants performed an interleaved choice test in which they could freely choose either hand for reaching. Furthermore, to investigate the effect of temporal changes on arm dynamics and hand choice, we exposed the same participants to another condition in which the force field was introduced gradually. When the abrupt force was applied, use of the perturbed hand significantly decreased and not changed during the training. In contrast, when the incremental force was applied, use of the perturbed hand gradually decreased as force increased. Surprisingly, even though the final amount of force was identical between the two conditions, hand choice was significantly biased toward the unperturbed hand in the gradual condition. These results suggest that time-varying changes in arm dynamics may have a greater influence on hand choice than the amplitude of the resistant force itself.

  16. A dynamic model for generating actuator specifications for small arms barrel active stabilization

    Due to stresses encountered in combat, it is known that soldier marksmanship noticeably decreases regardless of prior training. Active stabilization systems in small arms have potential to address this problem to increase soldier survivability and mission effectiveness. The key to success is proper actuator design, but this is highly dependent on proper specification which is challenging due to the human/weapon interaction. This paper presents a generic analytical dynamic model which is capable of defining the necessary actuation specifications for a wide range of small arms platforms. The model is unique because it captures the human interface--shoulder and arm--that introduces the jitter disturbance in addition to the geometry, inertial properties and active stabilization stiffness of the small arms platform. Because no data to date is available for actual shooter-induced disturbance in field conditions, a method is given using the model to back-solve from measured shooting range variability data the disturbance amplitude information relative to the input source (arm or shoulder). As examples of the applicability of the model to various small arms systems, two different weapon systems were investigated: the M24 sniper weapon and the M16 assault rifle. In both cases, model based simulations provided valuable insight into impact on the actuation specifications (force, displacement, phase, frequency) due to the interplay of the human-weapon-active stabilization interface including the effect of shooter-disturbance frequency, disturbance location (shoulder vs. arm), and system parameters (stiffness, barrel rotation).

  17. Arms control verification costs: the need for a comparative analysis

    International Nuclear Information System (INIS)

    The end of the Cold War era has presented practitioners and analysts of international non-proliferation, arms control and disarmament (NACD) the opportunity to focus more intently on the range and scope of NACD treaties and their verification. Aside from obvious favorable and well-publicized developments in the field of nuclear non-proliferation, progress also has been made in a wide variety of arenas, ranging from chemical and biological weapons, fissile material, conventional forces, ballistic missiles, to anti-personnel landmines. Indeed, breaking from the constraints imposed by the Cold War United States-Soviet adversarial zero-sum relationship that impeded the progress of arms control, particularly on a multilateral level, the post Cold War period has witnessed significant developments in NACD commitments, initiatives, and implementation. The goals of this project - in its final iteration - will be fourfold. First, it will lead to the creation of a costing analysis model adjustable for uses in several current and future arms control verification tasks. Second, the project will identify data accumulated in the cost categories outlined in Table 1 in each of the five cases. By comparing costs to overall effectiveness, the application of the model will demonstrate desirability in each of the cases (see Chart 1). Third, the project will identify and scrutinize 'political costs' as well as real expenditures and investment in the verification regimes (see Chart 2). And, finally, the project will offer some analysis on the relationship between national and multilateral forms of arms control verification, as well as the applicability of multilateralism as an effective tool in the verification of international non-proliferation, arms control, and disarmament agreements.

  18. Note: A rigid piezo motor with large output force and an effective method to reduce sliding friction force

    International Nuclear Information System (INIS)

    We present a completely practical TunaDrive piezo motor. It consists of a central piezo stack sandwiched by two arm piezo stacks and two leg piezo stacks, respectively, which is then sandwiched and spring-clamped by a pair of parallel polished sapphire rods. It works by alternatively fast expanding and contracting the arm/leg stacks while slowly expanding/contracting the central stack simultaneously. The key point is that sufficiently fast expanding and contracting a limb stack can make its two sliding friction forces well cancel, resulting in the total sliding friction force is <10% of the total static friction force, which can help increase output force greatly. The piezo motor's high compactness, precision, and output force make it perfect in building a high-quality harsh-condition (vibration resistant) atomic resolution scanning probe microscope

  2. Dielectrophoresis force of colloidal nanoparticles

    Science.gov (United States)

    Huang, Hao; Ou-Yang, Daniel

    Dielectrophoresis (DEP) is the motion of a polarizable colloidal particle in a non­uniform electric field. The magnitude of the DEP force is known to be proportional to the gradient of E2. The DEP force also depends on the relative polarizability of the particle to that of the surrounding medium. Due to its ease of use, DEP has been proposed for a variety of applications to manipulate colloidal particles in a microfluidic setting. However, accurate measurements of the DEP force on colloidal nanoparticles are lacking. A new method is proposed to measure accurately the DEP potential force of colloidal nanoparticles by using confocal fluorescence imaging to determine the density distributions of dilute colloidal nanoparticle in a DEP potential force field. The DEP potential field can be calculated from the particle density distributions since the spatial distribution of the particle number density follows the Boltzmann distribution of the DEP potential energy. The validity of the measured DEP force is tested by examining the force as a function of the E field strength and particle size. The classic Maxwell­Wagner­O'Konski is found to be inadequate to fully describe the frequency dependence of the DEP force.

    Full Text Available The single party was the militarized political institution of the new authoritarian regime lead by King Carol II by using the armed hand of single organization in the state, The National Guard. The militarization of policy represented the main dimension of the regime and the state architecture revealed the single party capacity to militarize the administrative institutions. The architecture of National Renaissance Front was similar to a military unit, the official attributions of the National Guard consisted in the maintenance of order in the territory, and unofficially regarded the monitoring of members and opposites of the party and regime, by control and surveillance activity. The National Guard was politicized institution of the regime and of the single party which proved its inefficiency because of the subordination of the commandant general to the single party. Militaries lead the single organization as well as the National Guard.

    Although some form of commercial instrument mounting arm is available, a paucity of information in the literature may cause problems in selecting the most appropriate model for an ENT department wishing to trial their invention for use in the clinic or operating theatre. The instrument mounting arm described here is based on existing designs used by hobbyists and model makers for many years but the main benefit of this innovation is its multi-purpose use in the operating theatre and cost effectiveness since it is made of aluminum alloy. It is compact, stable and easily adjustable and can incorporate an endoscope holder or an operating end piece to mount various ENT instruments that offers considerable advantages to the unassisted operator.

  6. Telescopic arm with automatic advance

    International Nuclear Information System (INIS)

    By means of the telescopic arm TV cameras, tools or the like can be moved in and out of reactor pressure vessels. For pressure and traction driving element a curved steel band is used which is guided in the central axis of the telescopic arm by means of one adapting element each per telescopic member. On advancing the steel band, which can absorb considerable bending moments, is drawn out of a cartridge with a spool, by meanes of friction rollers. A nozzle-shaped device in front of the cartridge is flattering the steel band before winding it up. The free buckling length of the stell band is never greater than the distance between two adapting elements (part in the shape of a parallelpiped with a slot for guiding the steel band) resp. the length of a telescopic member.

    1994-02-01

    The hand-arm vibration syndrome affects workers who perform tasks that generate vibration. Raynaud's phenomenon and sensory impairment of the fingers are the predominant effects. A history of hand-arm vibration (HAV) exposure in a patient with these symptoms should alert the physician to the diagnosis. Referral to a special clinic or hospital department for multiple clinical tests is required to confirm the diagnosis and, using the Stockholm classification, to grade the severity in each hand. The assessment permits the patient to be monitored either for progression of or recovery from the syndrome. Avoidance of further vibration exposure is recommended, together with the prescription of a slow-release calcium channel blocker to improve peripheral circulation. Hand-arm vibration syndrome should be distinguished from carpal tunnel syndrome (CTS), which may have similar symptomatology but requires different treatments. Surgery is contraindicated in the former and should be the last resort for carpal tunnel syndrome in a worker requiring good grip-strength in future employment. PMID:8185734

    2015-10-01

    Full Text Available Flexible tactile sensors capable of detecting the magnitude and direction of the applied force together are of great interest for application in human-interactive robots, prosthetics, and bionic arms/feet. Human skin contains excellent tactile sensing elements, mechanoreceptors, which detect their assigned tactile stimuli and transduce them into electrical signals. The transduced signals are transmitted through separated nerve fibers to the central nerve system without complicated signal processing. Inspired by the function and organization of human skin, we present a piezoresistive type tactile sensor capable of discriminating the direction and magnitude of stimulations without further signal processing. Our tactile sensor is based on a flexible core and four sidewall structures of elastomer, where highly sensitive interlocking piezoresistive type sensing elements are embedded. We demonstrate the discriminating normal pressure and shear force simultaneously without interference between the applied forces. The developed sensor can detect down to 128 Pa in normal pressure and 0.08 N in shear force, respectively. The developed sensor can be applied in the prosthetic arms requiring the restoration of tactile sensation to discriminate the feeling of normal and shear force like human skin.

    This work identifies the probable strategic characteristics of the interconnected North-Northeast Brazilian electricity industry, after the current restructuring and privatization process has been implemented. It is a 15.0 thousand MW generation industry supplying more than 33.5 million consumers. The normative scenery for analysis of the electricity industry takes into consideration the premises that the government establishes the vertical separation of generation, transmission, distribution and retailing, and introduces the regulation to a competitive industrial structure in generation and retailing. It is assumed that free access to transmit and distribute electricity and broad choices for consumers are the main features for competition in both generation and retailing. The essence of formulating strategy is to relate a company with its environment, considering the industrial structure. Porter's five forces model for industry environment and competition, emphasizing the role of the government in such regulated industry, is the basic theoretical reference. The main strategic characteristics related to entry barriers, rivalry intensity, supplier power, customer power and substitute products are analyzed. (author)

  13. Issues related to choosing a guard force structure

    International Nuclear Information System (INIS)

    The establishment of a federal security force has been suggested as an additional step to protect nuclear material. The force would be given the responsibility for guarding nuclear facilities and shipments of nuclear materials. A study to identify the issues that are relevant to choosing between the private guard forces that are presently employed by industry or a guard force under federal authority is summarized. To examine the issues which would be relevant, three possible types of security force structures were selected for comparison: a federal force under central authority, a private guard force employed by or under contract to a facility, and a private arrangement to employ local police officers similar to the arrangement for armed guards at airports. The issues were divided into seven categories: (1) legal considerations, (2) liability, (3) staffing and operations, (4) costs, (5) relationship to off-site forces, (6) management and control, and (7) transportation.

  14. Method and apparatus for adaptive force and position control of manipulators

    1995-01-01

    The described and improved multi-arm invention of this application presents three strategies for adaptive control of cooperative multi-arm robots which coordinate control over a common load. In the position-position control strategy, the adaptive controllers ensure that the end-effector positions of both arms track desired trajectories in Cartesian space despite unknown time-varying interaction forces exerted through a load. In the position-hybrid control strategy, the adaptive controller of one arm controls end-effector motions in the free directions and applied forces in the constraint directions; while the adaptive controller of the other arm ensures that the end-effector tracks desired position trajectories. In the hybrid-hybrid control strategy, the adaptive controllers ensure that both end-effectors track reference position trajectories while simultaneously applying desired forces on the load. In all three control strategies, the cross-coupling effects between the arms are treated as disturbances which are compensated for by the adaptive controllers while following desired commands in a common frame of reference. The adaptive controllers do not require the complex mathematical model of the arm dynamics or any knowledge of the arm dynamic parameters or the load parameters such as mass and stiffness. Circuits in the adaptive feedback and feedforward controllers are varied by novel adaptation laws.

    This report reviews the arms-control policy and decision-making process of the last several administrations with the emphasis on how frictional forces, not unlike those discussed by von Clausewitz, affect the process. It is discusses friction within administrations, as a result of Congressional actions, from nongovernmental organizations, and from the media. Friction is present in every process involving individuals and organizations with differing views and objectives. It may not be desirable to remove all friction from the process, even if it were possible to do so, lest the decision makers stifle creativity and lose the benefit of a variety of views and approaches.

  16. Bionic robot arm with compliant actuators

    Moehl, Bernhard

    2000-10-01

    Traditional robotics uses non-compliant materials for all components involved in the production of movement. Elasticity is avoided as far as possible, because it leads to hazardous oscillations and makes control of precise movements very difficult. Due to this deliberate stiffness, robots are typically heavy and clumsy structures in comparison to their living counterparts (i.e. man and animals). Yet, moving systems in nature cope not only with the difficulties introduced by compliant materials, they also take advantage of the elasticity in muscles and tendons to produce smooth and even rapid movements. It is understood, that elasticity in a multi-jointed moving system requires sophisticated control mechanisms- as provided by a nervous system or a suitably programmed computer. In this contribution I shall describe a two-jointed robot with purpose-built elasticity in its actuators. This is accomplished by spiral springs places in series with a conventional electric motor and a tendon to the arm. It is shown that, with sufficiently soft elasticity, oscillations can be avoided by active oscillation damping. (Such active oscillation damping presumably also governs movement control in man and animals.) Furthermore, once the major problem has been overcome, elasticity is found to offer a wide spectrum of valuable advantages, as far as the most serious problems in traditional robotics are concerned. They are summarized by terms such as less dangerous, position tolerant, lightweight construction, controlled forces, and ballistic movements. These will be explained in detail and presented for discussion.

    2011-05-01

    In this study, we used recently developed technology to determine the force-time profile of elite swimmers, which enabled coaches to make informed decisions on technique modifications. Eight elite male swimmers with a FINA (Federation Internationale de Natation) rank of 900+ completed five passive (streamline tow) and five net force (arms and leg swimming) trials. Three 50-Hz cameras were used to video each trial and were synchronized to the kinetic data output from a force-platform, upon which a motorized towing device was mounted. Passive and net force trials were completed at the participant's maximal front crawl swimming velocity. For the constant tow velocity, the net force profile was presented as a force-time graph, and the limitation of a constant velocity assumption was acknowledged. This allowed minimum and maximum net forces and arm symmetry to be identified. At a mean velocity of 1.92+0.06 m s⁻¹, the mean passive drag for the swimmers was 80.3+4.0 N, and the mean net force was 262.4+33.4 N. The mean location in the stroke cycle for minimum and maximum net force production was at 45% (insweep phase) and 75% (upsweep phase) of the stroke, respectively. This force-time profile also identified any stroke asymmetry. PMID:21500079

    To achieve its long-term goal of sending humans to Mars, the National Aeronautics and Space Administration (NASA) plans to proceed in a series of incrementally more complex human spaceflight missions. Today, human flight experience extends only to Low-Earth Orbit (LEO), and should problems arise during a mission, the crew can return to Earth in a matter of minutes to hours. The next logical step for human spaceflight is to gain flight experience in the vicinity of the Moon. These cis-lunar missions provide a "proving ground" for the testing of systems and operations while still accommodating an emergency return path to the Earth that would last only several days. Cis-lunar mission experience will be essential for more ambitious human missions beyond the Earth-Moon system, which will require weeks, months, or even years of transit time. In addition, NASA has been given a Grand Challenge to find all asteroid threats to human populations and know what to do about them. Obtaining knowledge of asteroid physical properties combined with performing technology demonstrations for planetary defense provide much needed information to address the issue of future asteroid impacts on Earth. Hence the combined objectives of human exploration and planetary defense give a rationale for the Asteroid Re-direct Mission (ARM). Mission Description: NASA's ARM consists of two mission segments: 1) the Asteroid Redirect Robotic Mission (ARRM), the first robotic mission to visit a large (greater than ~100 m diameter) near-Earth asteroid (NEA), collect a multi-ton boulder from its surface along with regolith samples, demonstrate a planetary defense technique, and return the asteroidal material to a stable orbit around the Moon; and 2) the Asteroid Redirect Crewed Mission (ARCM), in which astronauts will take the Orion capsule to rendezvous and dock with the robotic vehicle, conduct multiple extravehicular activities to explore the boulder, and return to Earth with samples. NASA's proposed

  20. Learning and Control Model of the Arm for Loading

    Science.gov (United States)

    Kim, Kyoungsik; Kambara, Hiroyuki; Shin, Duk; Koike, Yasuharu

    We propose a learning and control model of the arm for a loading task in which an object is loaded onto one hand with the other hand, in the sagittal plane. Postural control during object interactions provides important points to motor control theories in terms of how humans handle dynamics changes and use the information of prediction and sensory feedback. For the learning and control model, we coupled a feedback-error-learning scheme with an Actor-Critic method used as a feedback controller. To overcome sensory delays, a feedforward dynamics model (FDM) was used in the sensory feedback path. We tested the proposed model in simulation using a two-joint arm with six muscles, each with time delays in muscle force generation. By applying the proposed model to the loading task, we showed that motor commands started increasing, before an object was loaded on, to stabilize arm posture. We also found that the FDM contributes to the stabilization by predicting how the hand changes based on contexts of the object and efferent signals. For comparison with other computational models, we present the simulation results of a minimum-variance model.

  1. Arms control in the last year of the Reagan administration

    Energy Technology Data Exchange (ETDEWEB)

    Nunn, S.

    1988-03-01

    Senator Nunn says it is conceivable that, during 1988, the Senate could have five major arms-control agreements placed on its calendar. In addition to the INF Treaty, the Senate could, prior to adjournment in the fall, be presented with a START treaty, a new accord, on strategic defenses, and new protocols on verification of nuclear testing which could clear the way for ratification of the long-pending Threshold Test Ban and Peaceful Nuclear Explosions Treaties. I hasten to add, however, that the odds that such a new dawn could break during the last year of the Reagan administration are not more than 50/50. Whether 1988 is the occasion for such dramatic arms-control agreements will depend, of course, on unprecedented Soviet cooperation. Under Gorbachev, the Soviets have voiced an apparent willingness to embrace arms-control concepts which just a few years ago would have seemed unattainable. These include disproportionate Soviet reductions, on-site inspection, cooperative measures for enhancing national technical means of verification, detailed data exchanges, high-level military meetings, discussions on doctrine and force postures, and important nuclear risk reduction measures. A word of caution is in order. It is too soon to determine how many of these concepts can be translated into reality. The West must predicate its positions on Soviet deeds, not words. Nevertheless, the advent of Gorbachev, glasnost, and perestroika has undeniably improved the overall climate for the conduct of superpower relations.

  2. Regional dialogue and multilateral arms control efforts today

    International Nuclear Information System (INIS)

    The significance of arms control and non-proliferation tasks is stressed emphasising what has been done, and-more important-what must still be done. Although tangible developments at the regional level may seem at times to be slow in coming, it is important to remember that the United States-Soviet transition from voluntary declarations to detailed arms control agreements with intrusive verification regimes spanned the entire length of cold war. Given the instabilities afflicting these regions, establishing a regional dialogue is itself a confidence-building measure. The experience of the United States and the former Soviet Union amply demonstrates that mere existence of regular dialogue can reduce tension by providing a platform for communication among military and Government participants even when political crisis prevents diplomatic contacts at senior levels. The international community should be encouraged by the progress that has been made to date to address regional instabilities. Such steps are an integral part of the international effort, carried out both at the United Nations and elsewhere, to adopt acceptable levels of conventional military forces and to eliminate weapons of mass destruction. Given the instabilities afflicting these regions, establishing a regional dialogue is itself a confidence-building measure. World changes, while potentially dangerous and certainly challenging, offer the hope of replacing antagonism with cooperation, creating a progressively more democratic global environment, preventing proliferation, and dampening regional conflicts. Continuing to make effective use of the entire mix of arms control and confidence-building tools will help to realize these hopes

  3. Institutional plan -- Institute of Nuclear Power Operations, 1993

    1993-12-31

    The US nuclear electric utility industry established the Institute of Nuclear Power Operations (INPO) in 1979 to promote the highest levels of safety and reliability -- to promote excellence -- in the operation of its nuclear plants. After its formation, the Institute grew from a handful of on-loan personnel in late 1979 to an established work force of more than 400 permanent and on-loan personnel. INPO`s early years were marked by growth and evolution of its programs and organization. The Institute now focuses primarily on the effectiveness and enhancement of established programs and activities. For INPO to carry out its role, it must have the support of its members and participants and a cooperative but independent relationship with the NRC. A basis for that support and cooperation is an understanding of INPO`s role. This Institutional Plan is intended to provide that understanding by defining the Institute`s role and its major programs. This plan considers the existing and projected needs of the industry and the overall environment in which INPO and its members and participants operate.

  7. A comprehensive approach to nuclear arms control

    International Nuclear Information System (INIS)

    Cold war nuclear arms control was characterized by American Soviet hostility and the limits of verification; the end of the cold war allowed for a more cooperative approach. From this new situation emerged the idea of a new agenda for arms control and of exploring a more comprehensive approach to nuclear arms control. The author posits eight elements for such a comprehensive approach. Though such an approach seems unrealistic today, recent history teaches us to look beyond today's constraints. (author)

    2007-09-01

    Full Text Available Abstract Background In humans, the implementation of multijoint tasks of the arm implies a highly complex integration of sensory information, sensorimotor transformations and motor planning. Computational models can be profitably used to better understand the mechanisms sub-serving motor control, thus providing useful perspectives and investigating different control hypotheses. To this purpose, the use of Artificial Neural Networks has been proposed to represent and interpret the movement of upper limb. In this paper, a neural network approach to the modelling of the motor control of a human arm during planar ballistic movements is presented. Methods The developed system is composed of three main computational blocks: 1 a parallel distributed learning scheme that aims at simulating the internal inverse model in the trajectory formation process; 2 a pulse generator, which is responsible for the creation of muscular synergies; and 3 a limb model based on two joints (two degrees of freedom and six muscle-like actuators, that can accommodate for the biomechanical parameters of the arm. The learning paradigm of the neural controller is based on a pure exploration of the working space with no feedback signal. Kinematics provided by the system have been compared with those obtained in literature from experimental data of humans. Results The model reproduces kinematics of arm movements, with bell-shaped wrist velocity profiles and approximately straight trajectories, and gives rise to the generation of synergies for the execution of movements. The model allows achieving amplitude and direction errors of respectively 0.52 cm and 0.2 radians. Curvature values are similar to those encountered in experimental measures with humans. The neural controller also manages environmental modifications such as the insertion of different force fields acting on the end-effector. Conclusion The proposed system has been shown to properly simulate the development of

  13. Changing patterns of US arms transfers

    Energy Technology Data Exchange (ETDEWEB)

    Salomone, M.D.

    1985-01-01

    The thesis has three purposes. First is to explore the changing patterns of US arms transfers from Fiscal Year 1950 (FY 1950) through Fiscal Year 1980 (FY 1980). Second, is to describe and assess the decision-making process for arms transfers within the US Government. Third is to examine and critique the conventional wisdom concerning US arms transfers, to support that wisdom, or to offer an alternate empirically supported view. The conventional wisdom about US arms transfer is that they have been rising at an alarming rate, and that this is the result of an arms transfer decision-making process which is out of control. This belief is founded on an empirically based proposition that arms transfers have been rising at an alarming rate. However, this proposition has never been empirically validated. To explore this conventional wisdom, the author establishes the historical, political and defense policy contexts for US arms transfers over the period FY 1950 through FY 1980. The author critiques the conventional wisdom about US arms transfers, analyzes the many ways that arms transfers have been measured, and explores the impediments to accurate measurement and assessment of the phenomenon.

    2012-01-01

    Humanoid robots are designed and built to mimic human form and movement.Ultimately,they are meant to resemble the size and physical abilities of a human in order to function in human-oriented environments and to work autonomously but to pose no physical threat to humans.Here,a humanoid robot that resembles a human in appearance and movement is built using powerful actuators paired with gear trains,joint mechanisms,and motor drivers that are all encased in a package no larger than that of the human physique.In this paper,we propose the construction of a humanoid-applicable anthropomorphic 7-DoF arm complete with an 8-DoF hand.The novel mechanical design of this humanoid arm makes it sufficiently compact to be compatible with currently available narrating-model humanoids,and to be sufficiently powerful and flexible to be functional; the number of degrees of freedom endowed in this robotic arm is sufficient for executing a wide range of tasks,including dexterous hand movements.The developed humanoid arm and hand are capable of sensing and interpreting incoming external force using the motor in each joint current without conventional torque sensors.The humanoid arm adopts an algorithm to avoid obstacles and the dexterous hand is capable of grasping objects.The developed robotic arm is suitable for use in an interactive humanoid robot.

    2016-01-01

    Full Text Available In this study, 2 DOF mathematical models of Pitman arm steering system are derived using Newton’s law of motion and modeled in MATLAB/SIMULINK software. The developed steering model is included with a DC motor model which is directly attached to the steering column. The Pitman arm steering model is then validated with actual Pitman arm steering test rig using various lateral inputs such as double lane change, step steer, and slalom test. Meanwhile, a position tracking control method has been used in order to evaluate the effectiveness of the validated model to be implemented in active safety system of a heavy vehicle. The similar method has been used to test the actual Pitman arm steering mechanism using hardware-in-the-loop simulation (HILS technique. Additional friction compensation is added in the HILS technique in order to minimize the frictional effects that occur in the mechanical configuration of the DC motor and Pitman arm steering. The performance of the electronically actuated Pitman arm steering system can be used to develop a firing-on-the-move actuator (FOMA for an armored vehicle. The FOMA can be used as an active safety system to reject unwanted yaw motion due to the firing force.

    Background Tennis elbow (TE) is a common musculotendinous degenerative disorder of the extensor origin at the lateral humeral epicondyle. Different modes of treatment are used for management of tennis elbow. Objectives This study investigated the effect of the taping technique (TT) on pain, grip strength and wrist extension force in treatment of tennis elbow. Patients and Methods Thirty patients (16 men /14 women with a mean age of 32.2 years) with tennis elbow of their dominant arm participated in this study. Outcome measures were assessment of pain at the lateral aspect of the elbow, grip strength and wrist extension force before and five to ten minutes after application of elbow tape on the affected and unaffected arms. A Visual Analog Scale was used to assess pain. A dynamometer and a hand-held dynamometer were used for evaluation of grip strength and wrist extension force, respectively. Results Among the variables, significant differences were found in wrist extension forces between effected and unaffected arms (P = 0.02). Changes in grip strength showed statically significant improvements in the affected arm compared to the unaffected arm (P = 0.03). Also, in assessment of pain at the lateral epicondyle, the mean change between affected and unaffected arms was significant, with P = 0.001. Conclusions The taping technique, as applied in this study demonstrates an impressive effect on wrist extension force and grip strength of patients with TE. Elbow taping also reduces pain at the lateral aspect of the elbow in these patients. PMID:24350156

  2. VFI-based Robotic Arm Control for Natural Adaptive Motion

    Directory of Open Access Journals (Sweden)

    Woosung Yang

    2014-03-01

    Full Text Available Since neural oscillator based control methods can generate rhythmic motion without information on system dynamics, they can be a promising alternative to traditional motion planning based control approaches. However, for field application, they still need to be robust against unexpected forces or changes in environments so as to be able to generate “natural motion” like most biological systems. In this study a biologically inspired control algorithm that combines neural oscillators and virtual force is proposed. This work gives the condition with respect to parameters tuning to stably activate the neural oscillators. This is helpful to achieve motion adaptability to environmental changes keeping the motion repeatability. He efficacy and efficiency of the proposed methods are tested in the control of a planar three-linkage robotic arm. It is shown that the proposed controller generates a given circular path stably and repeatedly, even with unexpected contact with a wall. The adaptivity of motion control is also tested in control of a robotic arm with redundant degrees of freedom. The proposed control algorithm works throughout the simulations and experiments.

    1995-01-01

    The European Robotic Arm (ERA) is a contribution to the Russian Segment of the International Space Station Alpha. It will start operating on the Russian Segment during the assembly phase. ERA is designed and produced by a large industrial consortium spread over Europe with Fokker Space & Systems as prime contractor. In this paper, we will describe some of the overall design aspects and focus on the development of several mechanisms within ERA. The operation of ERA during the approach of its end effector towards the grapple interface and the grapple operation is discussed, with a focus on mechanisms. This includes the geometry of the end effector leading edge, which is carefully designed to provide the correct and complete tactile information to a torque-force sensor (TFS). The data from this TFS are used to steer the arm such that forces and moments are kept below 20 N and 20 N.m respectively during the grappling operation. Two hardware models of the end effector are built. The problems encountered are described as well as their solutions. The joints in the wrists and the elbow initially used a harmonic drive lubricated by MoS2. During development testing, this combination showed an insufficient lifetime in air to survive the acceptance test program. The switch-over to a system comprising planetary gearboxes with grease lubrication is described. From these development efforts, conclusions are drawn and recommendations are given for the design of complex space mechanisms.

    1989-01-01

    The KALI distributed robot programming and control environment is described within the context of its use in the Jet Propulsion Laboratory (JPL) telerobot project. The purpose of KALI is to provide a flexible robot programming and control environment for coordinated multi-arm robots. Flexibility, both in hardware configuration and software, is desired so that it can be easily modified to test various concepts in robot programming and control, e.g., multi-arm control, force control, sensor integration, teleoperation, and shared control. In the programming environment, user programs written in the C programming language describe trajectories for multiple coordinated manipulators with the aid of KALI function libraries. A system of multiple coordinated manipulators is considered within the programming environment as one motion system. The user plans the trajectory of one controlled Cartesian frame associated with a motion system and describes the positions of the manipulators with respect to that frame. Smooth Cartesian trajectories are achieved through a blending of successive path segments. The manipulator and load dynamics are considered during trajectory generation so that given interface force limits are not exceeded.

    The most commonly used propulsion method for handcycling is moving the arms symmetrically. Previous studies indicated that during outdoor handcycling symmetrical arm movements are more efficient. During locomotor movements, however, arm movements are performed asymmetrically in combination with leg movements. We questioned which combination of arm and leg movements is more efficient during combined arm and leg cycling for stationary use.

  11. Design of a biomimetic robotic octopus arm

    International Nuclear Information System (INIS)

    This paper reports the rationale and design of a robotic arm, as inspired by an octopus arm. The octopus arm shows peculiar features, such as the ability to bend in all directions, to produce fast elongations, and to vary its stiffness. The octopus achieves these unique motor skills, thanks to its peculiar muscular structure, named muscular hydrostat. Different muscles arranged on orthogonal planes generate an antagonistic action on each other in the muscular hydrostat, which does not change its volume during muscle contractions, and allow bending and elongation of the arm and stiffness variation. By drawing inspiration from natural skills of octopus, and by analysing the geometry and mechanics of the muscular structure of its arm, we propose the design of a robot arm consisting of an artificial muscular hydrostat structure, which is completely soft and compliant, but also able to stiffen. In this paper, we discuss the design criteria of the robotic arm and how this design and the special arrangement of its muscular structure may bring the building of a robotic arm into being, by showing the results obtained by mathematical models and prototypical mock-ups

    At the University of Florida we developed the University of Florida LISA Interferometer Simulator (UFLIS) in order to study LISA interferometry with hardware in the loop at a system level. One of the proposed laser frequency stabilization techniques in LISA is arm locking. Arm locking uses an adequately filtered linear combination of the LISA arm signals as a frequency reference. We will report about experiments in which we demonstrated arm locking using UFLIS. During these experiments we also discovered a problem associated with the Doppler shift of the return beam. The initial arm locking publications assumed that this Doppler shift can perfectly be subtracted inside the phasemeter or adds an insignificant offset to the sensor signal. However, the remaining Doppler knowledge error will cause a constant change in the laser frequency if unaccounted for. Several ways to circumvent this problem have been identified. We performed detailed simulations and started preliminary experiments to verify the performance of the proposed new controller designs.

    This essay intends to offer a comment on concepts, trends and attitudes concerning arms control and strategic stability with reference to the current international security situation. It also offers observations from two different perspectives about strategic stability: one proceeds from the concept of universal security and aims to prevent conflicts and instability from disrupting regional and international security environment on which nation states depend so much for their peaceful development; the other starts from maintaining the global leadership by a super power and aiming to contain any challenge that sways or is likely to sway its dominating status. If China and the United States commit themselves to the undertaking of a new type of major powers relationship that stresses win-win cooperation, they will be able to contribute greatly to a stable international security architecture that is good for world peaceful development.

  19. Surface Sampler Arm Acquiring Sample

    Science.gov (United States)

    1976-01-01

    Operation of the surface sampler in obtaining Martian soil for Viking 2's molecular analysis experiment last Saturday (September 25) was closely monitored by one of the Lander cameras because of the precision required in trenching the small area--8 by 9 inches-surrounded by rocks. Dubbed 'Bonneville Salt Flats,' the exposure of thin crust appeared unique in contrast with surrounding materials and became a prime target for organic analysis in spite of potential hazards. Large rock in foreground is 8 inches high. At left, the sampler scoop has touched the surface, missing the rock at upper left by a comfortable 6 inches, and the backhoe has penetrated the surface about one-half inch. The scoop was then pulled back to sample the desired point and (second photo) the backhoe furrowed the surface pulling a piece of thin crust toward the spacecraft. The initial touchdown and retraction sequence was used to avoid a collision between a rock in the shadow of the arm and a plate joining the arm and scoop. The rock was cleared by 2 to 3 inches. The third picture was taken 8 minutes after the scoop touched the surface and shows that the collector head has acquired a quantity of soil. With surface sampler withdrawn (right), the foot-long trench is seen between the rocks. The trench is three inches wide and about 1 1/2 to 2 inches deep. The scoop reached to within 3 inches of the rock at far end of trench. Penetration appears to have left a cavernous opening roofed by the crust and only about one inch of undisturbed crust separates the deformed surface and the rock.

    Full Text Available Corporate identity is planning and reşecting memorable, personal, characteristic pecularities of an institution and the ability that separates it from others. Corporate identity is in interaction with the corporate culture and corporate image. It is an entity formed by the philosophy of the institution, institutional communication, behavior and planning. Institutional planning formed by the planning of production and communication and architectural/ interior architectural planning, is the most significant element that constitutes the visual identity of an institution. While forming architectural and interior architectural planning of institutions, establishing places that will clearly reşect the corporate identity is gaining importance. In the perception of visual identity of institutions, planning elements such as; colour, texture, material and form are more significant than others.

    To achieve its long-term goal of sending humans to Mars, the National Aeronautics and Space Administration (NASA) plans to proceed in a series of incrementally more complex human spaceflight missions. Today, human flight experience extends only to Low-Earth Orbit (LEO), and should problems arise during a mission, the crew can return to Earth in a matter of minutes to hours. The next logical step for human spaceflight is to gain flight experience in the vicinity of the Moon. These cis-lunar missions provide a "proving ground" for the testing of systems and operations while still accommodating an emergency return path to the Earth that would last only several days. Cis-lunar mission experience will be essential for more ambitious human missions beyond the Earth-Moon system, which will require weeks, months, or even years of transit time. In addition, NASA has been given a Grand Challenge to find all asteroid threats to human populations and know what to do about them. Obtaining knowledge of asteroid physical properties combined with performing technology demonstrations for planetary defense provide much needed information to address the issue of future asteroid impacts on Earth. Hence the combined objectives of human exploration and planetary defense give a rationale for the Asteroid Re-direct Mission (ARM). Mission Description: NASA's ARM consists of two mission segments: 1) the Asteroid Redirect Robotic Mission (ARRM), the first robotic mission to visit a large (greater than ~100 m diameter) near-Earth asteroid (NEA), collect a multi-ton boulder from its surface along with regolith samples, demonstrate a planetary defense technique, and return the asteroidal material to a stable orbit around the Moon; and 2) the Asteroid Redirect Crewed Mission (ARCM), in which astronauts will take the Orion capsule to rendezvous and dock with the robotic vehicle, conduct multiple extravehicular activities to explore the boulder, and return to Earth with samples.

    International Nuclear Information System (INIS)

    Many who speak of the end of the Cold War emphasize the warming of international relations when they speak of the momentous consequences of this event. According to this image, the half century since Trinity has been a period of sparse international communication during which the Eastern and Western blocs hibernated in their isolated dens of security alliances. Yet it is equally valid to consider the implications of the end of the war footing that has underlain the policies of all of the major military powers during the last fifty years. While meaningful international dialogue was in a state of relative lethargy during much of this period, the military establishments of the Great Powers were actively engaged in using as much force as possible in their efforts to control world affairs, short of triggering a nuclear holocaust. International discourse, at least in English, was rife with such military images as appeasement, containment, crisis stability, and tripwires. From the military posture of the U.S. and Russia a tense peace ironically emerged, but the terms by which decisions were made about controlling weapons of mass destruction (i.e., nuclear, chemical, and biological weapons) were the terms of war. The thesis of this paper is that the end of the Cold War marks a shift away from reliance on military might toward an international commitment to control weapons of mass destruction through the rule of law developed by John Rawls. The progression of agreements during this century to limit weapons of mass destruction testifies to this new development.

  4. Phylogeny of diving beetles reveals a coevolutionary arms race between the sexes.

    Directory of Open Access Journals (Sweden)

    Johannes Bergsten

    Full Text Available BACKGROUND: Darwin illustrated his sexual selection theory with male and female morphology of diving beetles, but maintained a cooperative view of their interaction. Present theory suggests that instead sexual conflict should be a widespread evolutionary force driving both intersexual coevolutionary arms races and speciation. METHODOLOGY/PRINCIPAL FINDINGS: We combined Bayesian phylogenetics, complete taxon sampling and a multi-gene approach to test the arms race scenario on a robust diving beetle phylogeny. As predicted, suction cups in males and modified dorsal surfaces in females showed a pronounced coevolutionary pattern. The female dorsal modifications impair the attachment ability of male suction cups, but each antagonistic novelty in females corresponds to counter-differentiation of suction cups in males. CONCLUSIONS: A recently diverged sibling species pair in Japan is possibly one consequence of this arms race and we suggest that future studies on hypoxia might reveal the key to the extraordinary selection for female counter-adaptations in diving beetles.

    The automatic polishing process for three-dimensional forms, such as prototype models of products made of acrylic resin, are being required to develop in order to reduce cost and time consumption. This paper proposes a new polishing technique using magnetic compound fluid (MCF) and robotic arm. Firstly, a polishing unit, which can generate a dynamic magnetic field and be attachable to the robotic arm, is developed. This unit can hold MCF slurry that acts as a flexible and restorable polishing tool for the sake of magnetic force. Secondly, the effects of the clearance between workpiece and polishing unit, the composition of MCF slurry, the relative motion, the dynamic magnetic field and the supplied amount of slurry on polishing characteristics of acrylic resin are experimentally demonstrated. As a result, the smoothest surface roughness is achieved to below 10 nm Ra in a few min, and the feasibility of polishing the free-formed device by controlling robotic arm has been confirmed.

  8. Interactions between planar grafted neurofilament side-arms.

    2011-06-16

    The side-arms of neurofilaments (NFs) have been proposed to be highly disordered, leading to an entropically and electrostatically based repulsion that modulates interfilament spacing. To characterize the behavior of two interacting polymer brushes in a system of this type, we performed molecular dynamics simulations of neurofilament brushes using a four bead reduced amino acid set coarse-grained model. In these simulations, we examined components of the neurofilament brush, NF-L, NF-M, and phosphorylated NF-H (NF-HP), individually. Each protein type was grafted to planar surfaces and simulations were performed for a range of separations of two apposed grafted surfaces. The calculated force-separation curves show the force increases as the reciprocal separation as predicted for polyelectrolyte brushes at high salt. All three systems can be overlapped on a single force-separation curve, which is not expected given the variation in amino acid sequence and charges on the polymers. Examination of structural properties shows scaling behavior in the average brush height, end-to-end distance, and the density interpenetration. Some of this scaling can be understood in terms of treating the NF proteins as effective polyelectrolytes, but some cannot suggesting a distinct polyampholyte behavior. Correlations are found between oppositely charged residues in opposite brushes. However, these correlations are weak in comparison to the strong correlations within each brush. In comparison with recent experimental data that observes condensed and expanded gel states, our results suggest that the condensed state structure involves significant interdigitation of the side-arms.

    2013-01-01

    We study the influuence of the forcing on the steady turbulent states of a von K\\'arm\\'an swirling flow, at constant impeller speed, or at constant torque. We find that the different forcing conditions change the nature of the stability of the steady states and reveal dynamical regimes that bear similarities with low-dimensional systems. We suggest that this forcing dependence may be an out- of-equilibrium analogue of the ensemble inequivalence, valid for long-range interacting statistical systems, and that it may be applicable to other turbulent systems.

  12. A single magnetic nanocomposite cilia force sensor

    2016-04-20

    The advancements in fields like robotics and medicine continuously require improvements of sensor devices and more engagement of cooperative sensing technologies. For example, instruments such as tweezers with sensitive force sensory heads could provide the ability to sense a variety of physical quantities in real time, such as the amount and direction of the force applied or the texture of the gripped object. Force sensors with such abilities could be great solutions toward the development of smart surgical tools. In this work, a unique force sensor that can be integrated at the tips of robotic arms or surgical tools is reported. The force sensor consists of a single bioinspired, permanent magnetic and highly elastic nanocomposite cilia integrated on a magnetic field sensing element. The nanocomposite is prepared from permanent magnetic nanowires incorporated into the highly elastic polydimethylsiloxane. We demonstrate the potential of this concept by performing several experiments to show the performance of the force sensor. The developed sensor element has a 200 μm in diameter single cilium with 1:5 aspect ratio and shows a detection range up to 1 mN with a sensitivity of 1.6 Ω/mN and a resolution of 31 μN. The simple fabrication process of the sensor allows easy optimization of the sensor performance to meet the needs of different applications.

    2013-01-01

    Intraoperative imaging disrupts the rhythm of surgery despite providing an excellent opportunity for surgical monitoring and assessment. To allow surgery within real-time images, neuroArm, a teleoperated surgical robotic system, was conceptualized. The objective was to design and manufacture a magnetic resonance-compatible robot with a human-machine interface that could reproduce some of the sight, sound, and touch of surgery at a remote workstation. University of Calgary researchers worked with MacDonald, Dettwiler and Associates engineers to produce a requirements document, preliminary design review, and critical design review, followed by the manufacture, preclinical testing, and clinical integration of neuroArm. During the preliminary design review, the scope of the neuroArm project changed to performing microsurgery outside the magnet and stereotaxy inside the bore. neuroArm was successfully manufactured and installed in an intraoperative magnetic resonance imaging operating room. neuroArm was clinically integrated into 35 cases in a graded fashion. As a result of this experience, neuroArm II is in development, and advances in technology will allow microsurgery within the bore of the magnet. neuroArm represents a successful interdisciplinary collaboration. It has positive implications for the future of robotic technology in neurosurgery in that the precision and accuracy of robots will continue to augment human capability. PMID:23254809

  14. Naval arms control: Tons of options?

    International Nuclear Information System (INIS)

    Arms reductions have reached the US Navy, the most arms control averse of the US services, with budget-driven cuts in numbers of ships and personnel, and President Bush's unilateral withdrawal of tactical nuclear weapons. Soviet President Mikhail Gorbachev's rejoinder not only replicated the Bush initiative for naval weapons, but also called for the destruction of all those weapons, many of which would simply be placed in secure storage ashore under Bush's approach. Can formal, negotiated naval arms control agreements be far behind? Post-war history suggests that such naval arms agreements will remain out of reach. But post-war history has been confounded repeatedly by the events of the past three years. There are, in fact, negotiated naval limits that would enhance the predictability of US-Soviet military relations, and smooth the path of the naval retrenchment already underway on both sides. The Bush-Gorbachev reciprocal withdrawals of naval tactical nuclear arms deal with the most urgent and dangerous issue for naval arms control, improve the US Navy's survivability by drastically reducing the nuclear threat, and improve its flexibility by eliminating the security and political issues associated with carrying nuclear arms. It would be highly desirable, however, to formalize and verify these withdrawals, placing withdrawn weapons under jointly monitored, secure control, to preserve options for further cuts in the future

  15. The swim force as a body force

    Yan, Wen; Brady, John

    2015-11-01

    Net (as opposed to random) motion of active matter results from an average swim (or propulsive) force. It is shown that the average swim force acts like a body force - an internal body force [Yan and Brady, Soft Matter, DOI:10.1039/C5SM01318F]. As a result, the particle-pressure exerted on a container wall is the sum of the swim pressure [Takatori et al., Phys. Rev. Lett., 2014, 113, 028103] and the `weight' of the active particles. A continuum mechanical description is possible when variations occur on scales larger than the run length of the active particles and gives a Boltzmann-like distribution from a balance of the swim force and the swim pressure. Active particles may also display `action at a distance' and accumulate adjacent to (or be depleted from) a boundary without any external forces. In the momentum balance for the suspension - the mixture of active particles plus fluid - only external body forces appear.

    2009-01-01

    This work illustrates new tools and methods for an in vivo and direct, but non-invasive, measurement of an octopus arm mechanical properties. The active elongation (longitudinal stretch) and the pulling force capability are measured on a specimen of Octopus vulgaris in order to quantitatively characterize the parameters describing the arm mechanics, for biomimetic design purposes. The novel approach consists of observing and measuring a living octopus with minimally invasive methods, which allow the animal to move with its complete ability. All tools are conceived in order to create a collaborative interaction with the animal for the acquisition of active measures. The data analysis is executed taking into account the presence of an intrinsic error due to the mobility of the subject and the aquatic environment. Using a system of two synchronized high-speed high-resolution cameras and purpose-made instruments, the maximum elongation of an arm and its rest length (when all muscles fibres are relaxed during propulsion movement) are measured and compared to define the longitudinal stretch, with the impressive average result of 194%. With a similar setup integrated with a force sensor, the pulling force capability is measured as a function of grasp point position along the arm. The measured parameters are used as real specifications for the design of an octopus-like arm with a biomimetic approach. PMID:19965276

This scientific infrastructure, and resultant data archive, is a valuable national and international asset for advancing scientific knowledge of Earth systems. In fiscal year (FY) 2003, the DOE designated ARM sites as a national scientific user facility: the ARM Climate Research (ACRF). The ACRF has enormous potential to contribute to a wide range interdisciplinary science in areas such as meteorology, atmospheric aerosols, hydrology, biogeochemical cycling, and satellite validation, to name only a few.

  20. Pitch angle of galactic spiral arms

    International Nuclear Information System (INIS)

    One of the key parameters that characterizes spiral arms in disk galaxies is a pitch angle that measures the inclination of a spiral arm to the direction of galactic rotation. The pitch angle differs from galaxy to galaxy, which suggests that the rotation law of galactic disks determines it. In order to investigate the relation between the pitch angle of spiral arms and the shear rate of galactic differential rotation, we perform local N-body simulations of pure stellar disks. We find that the pitch angle increases with the epicycle frequency and decreases with the shear rate and obtain the fitting formula. This dependence is explained by the swing amplification mechanism.

    International Nuclear Information System (INIS)

    The continuation of the arms race and the failure of arms control and disarmament negotiations lend support to the belief that US and Soviet power, prestige, and security depend upon nuclear weapons. Therefore, the argument goes, the non-nuclear-weapon states (particularly those that are not allied with nuclear-weapon states and do not share their nuclear shield) may conclude that they would be well served by possession of these weapons. In this sense, the failure of nuclear arms reductions could create incentives for further proliferation

    Around the world, there are an estimated 300,000 to 500,000 children involved in armed conflict. Children can be abducted into a fighting force to fight or serve as sex slaves. Child soldiers have depression, anxiety, and posttraumatic stress symptoms; however, evidence is mixed because of methodologic limitations. Various mental health interventions have been tried, with promising results. Child and adolescent psychiatrists are uniquely trained in understanding and assisting youth to heal from such extraordinary experiences. A public health paradigm could include interventions that are based on a comprehensive assessment of interweaving developmental, biological, psychological, and sociocultural factors. PMID:26346388

    2015-12-01

    Full Text Available This paper presents a novel kinematic reconstruction of the human arm chain with five degrees of freedom and the estimation of the shoulder location during rehabilitation therapy assisted by end-effector robotic devices. This algorithm is based on the pseudoinverse of the Jacobian through the acceleration of the upper arm, measured using an accelerometer, and the orientation of the shoulder, estimated with a magnetic angular rate and gravity (MARG device. The results show a high accuracy in terms of arm joints and shoulder movement with respect to the real arm measured through an optoelectronic system. Furthermore, the range of motion (ROM of 50 healthy subjects is studied from two different trials, one trying to avoid shoulder movements and the second one forcing them. Moreover, the shoulder movement in the second trial is also estimated accurately. Besides the fact that the posture of the patient can be corrected during the exercise, the therapist could use the presented algorithm as an objective assessment tool. In conclusion, the joints’ estimation enables a better adjustment of the therapy, taking into account the needs of the patient, and consequently, the arm motion improves faster.

  5. Interpreting shadows: Arms control and defense planning in a rapidly changing multi-polar world

    1999-06-01

    The focus of arms control is changing. It now deals with issues affecting all nations and not just the super powers. A new framework for approaching non-proliferation of weapons of mass destruction and arms control could focus on a two-fold policy initiative. The first policy would be a new strategic `triad` built around conventional capability including rapidly deployable forces, regional ballistic missile defense, and long-range precision-strike capability. The second policy would employ an information strategy using the current diplomatic initiatives that appear to be the most productive, or unilateral and multilateral export controls, military assistance in the form of infrastructure, and confidence building measures. Continued success in arms control requires abandoning Cold War policies. Emerging policies will need to appreciate different world views. Good intelligence will be a key factor in the success of any policy orientation and its implementation. The focus needs to change from arms control involving the superpowers to arms control involving everyone.

    The ability to generate a high racket speed and a large amount of racket kinetic energy on impact is important for table tennis players. The purpose of this study was to understand how mechanical energy is generated and transferred in the racket arm during table tennis backhands. Ten male advanced right-handed table tennis players hit topspin backhands against pre-impact topspin and backspin balls. The joint kinetics at the shoulder, elbow and wrist of the racket arm was determined using inverse dynamics. A majority of the mechanical energy of the racket arm acquired during forward swing (65 and 77% against topspin and backspin, respectively) was due to energy transfer from the trunk. Energy transfer by the shoulder joint force in the vertical direction was the largest contributor to the mechanical energy of the racket arm against both spins and was greater against backspin than against topspin (34 and 28%, respectively). The shoulder joint force directed to the right, which peaked just before impact, transferred additional energy to the racket. Our results suggest that the upward thrust of the shoulder and the late timing of the axial rotation of the upper trunk are important for an effective topspin backhand. PMID:27111711

    In this study, a technique has been suggested to reduce a backpack load by transmitting determined loads to the children arm. The purpose of this paper is to estimate school children arm muscles while load carriage as well as to determine the safe load can be carried at wrist while walking with backpack. A mathematical model, as three DOFs model, was investigated in the sagittal plane and Lagrange multipliers method (LMM) was utilized to minimize a quadratic objective function of muscle forces. The muscle forces were minimized with three different load conditions which are termed as 0-L=0 N, 1-L=21.95 N, and 2-L=43.9 N. The investigated muscles were estimated and compared to their maximum forces throughout the load conditions. Flexor and extensor muscles were estimated and the results showed that flexor muscles were active while extensor muscles showed inactivity. The estimated muscle forces were didn't exceed their maximum forces with 0-L and 1-L conditions whereas biceps and FCR muscles exceeded their maximum forces with 2-L condition. Consequently, 1-L condition is quiet safe to be carried by hand whereas 2-L condition is not. Thus to reduce the load in the backpack the transmitted load shouldn't exceed 1-L condition.

    From the Sun's location in the Galactic disk, different arm tracers (CO, H I, hot dust, etc.) have been employed to locate a tangent to each spiral arm. Using all various and different observed spiral arm tracers (as published elsewhere), we embark on a new goal, namely the statistical analysis of these published data (data mining) to statistically compute the mean location of each spiral arm tracer. We show for a typical arm cross-cut, a separation of 400 pc between the mid-arm and the dust lane (at the inner edge of the arm, toward the Galactic center). Are some arms major and others minor? Separating arms into two sets, as suggested by some, we find the same arm widths between the two sets. Our interpretation is that we live in a multiple (four-arm) spiral (logarithmic) pattern (around a pitch angle of 12°) for the stars and gas in the Milky Way, with a sizable interarm separation (around 3 kpc) at the Sun's location and the same arm width for each arm (near 400 pc from mid-arm to dust lane).

  13. Youth Armed Groups in Colombia

    2014-09-01

    Full Text Available For the many years of Colombia’s civil war, youth have been trying to find their way in complicated and dangerous situations. A central component of this is their relationship with armed groups, something that has evolved considerably over the past ten years. This practice note examines the context within which these connections are formed and the implications this has for self/social identity and meaningful resistance. The ideas in this practice note are based on consultations with young Colombians, particularly those displaced from 2000-2013. These sessions included art activities, focus groups and individual interviews. Art activities involved descriptive and expressive projects so that participants could explore their feelings and memories of situations and experiences. This provided a base for group discussions where youth exchanged information and debated issues. A total of 34 workshops were held over a twelve year period. These consultations revealed how war flows all over young people, touching every aspect of their identity. The boundaries between the personal and political no longer exist in today’s civil wars, if indeed they every truly did. Young people growing up inside Colombia’s war understand this at a deep level. An acknowledgement of this pain – showing the connections between the personal and political dimensions of war – is, they would maintain, the basis for their personal healing as well as an important tool for the building of sustainable peace.

    1985-01-01

    From a new survey of the 2.6 mm line of CO in the southern Milky Way, 37 molecular clouds were identified along the Carina arm from l = 282 deg to 336 deg with masses generally greater than 10 to the 5th solar mass. The clouds lie approximately every 700 pc along a spiral segment that is nearly 25 kpc long and has a pitch of about 10 deg. The total mass of these clouds is 40 x 10 to the 6th solar mass, or rougly 1 x 10 to the 6th solar mass each on average. The abrupt tangent point in molecular clouds at l = 280 deg and the characteristic loop structure in the l-v diagram are unmistakable evidence of a CO spiral arm in Carina. This arm apparently connects with the northern hemisphere Sagittarius arm to form a single 10 deg spiral which extends more than two-thirds of the way around the Galaxy.

  7. Arms control and disarmament: A new conceptual approach

    International Nuclear Information System (INIS)

    In the frame of the Millennium Assembly of the UN, the Secretary-General urged the global community to seize a sense of the occasion that comes from the turning of the century, to step back from today's headlines and take a broader, longer-term view of the state of the world and the challenges it poses. In partnership with the Stockholm International Peace Research Institute (SIPRI), the Department for Disarmament Affairs (DDA) is taking up precisely that challenge. This panel discussion is part of a series of events sponsored by the Department to deepen the discussion on topical disarmament and security related issues. It is also part of the constant search for a new approach, a new concept, a new paradigm or vision for disarmament and arms control since the end of the cold war, the end of the post-cold war period and the beginning of the new century. It is axiomatic that progress in disarmament is closely linked to the evolution of the security environment. Disarmament cannot be separated from the new geo-political and security configurations in Europe, new demonstrations of nuclear capability in Asia, the emergence of new conflicts that are being driven mainly by internal and ethnic strife and that are outrageous in their brutality in Europe, Asia and Africa. Today's agenda is still full and diverse in the traditional areas of disarmament, nuclear, chemical and biological disarmament as well as ballistic missile defense and proliferation and conventional disarmament including landmines. Like many organizations, research institutes, researchers and individuals in the field of security, DDA has set store on the reliability and credibility of the research and publications produced by SIPRI. As an independent international institute for research on problems for peace and conflict, disarmament and arms control founded in 1966, SIPRI's primary research has been consistently objective, timely, comprehensive and clearly presented.

    2001-01-01

    DNA is of structural polymorphism, which is useful in nanoarchitecture; especially, four-arm DNA junc tions can be used to assemble nanowebs. The static four-arm DNA junctions were designed and synthesized. One-arm DNA and two-arm DNA came out simultaneously with the four-arm DNA junction's formation. A new method, termed the two-step method, was proposed and the productivity of four-arm DNA junctions was increased. A nanoweb was assembled successfully, but it showed irregularity itself. It was not the same as we expected. We consider that it is aresult from the flexibility of four-arm DNA junction.

  13. Arm & Interarm Star Formation in Spiral Galaxies

    Foyle, Kelly; Walter, Fabian; Leroy, Adam

    2010-01-01

    We investigate the relationship between spiral arms and star formation in the grand-design spirals NGC 5194 and NGC 628 and in the flocculent spiral NGC 6946. Filtered maps of near-IR (3.6 micron) emission allow us to identify "arm regions" that should correspond to regions of stellar mass density enhancements. The two grand-design spirals show a clear two-armed structure, while NGC 6946 is more complex. We examine these arm and interarm regions, looking at maps that trace recent star formation - far-ultraviolet (GALEX NGS) and 24 micron emission (Spitzer, SINGS) - and cold gas - CO (Heracles) and HI (Things). We find the star formation tracers and CO more concentrated in the spiral arms than the stellar 3.6 micron flux. If we define the spiral arms as the 25% highest pixels in the filtered 3.6 micron images, we find that the majority (60%) of star formation tracers occurs in the interarm regions; this result persists qualitatively even when considering the potential impact of finite data resolution and diffu...

  15. Arm pain in the workplace. A small area analysis.

    Science.gov (United States)

    Hadler, N M

    1992-02-01

    In the mid-1980s, use-related arm pain was recognized as a major issue for worker health and workplace safety. National policy targeted these "cumulative trauma disorders," "overuse syndromes," and "motion illnesses" for a "special emphasis program" by the Occupational Safety and Health Administration, a federal regulatory agency. The program begins with case recognition to identify the responsible ergonomic hazards with the goal of mandating ergonomic remedies. This report is a small area analysis of the impact of this process on the US West Communications, Inc work force. US West employs some 55,000 workers in 14 states. Commencing in the mid-1980s, workers in four of these states complained of upper extremity pain and were diagnosed as suffering from conditions encompassed by the "cumulative trauma disorders" rubric. The incidence was tenfold higher in one task category, directory assistance operators. No ergonomic descriptor can account for the four endemics of arm pain in directory assistance operators. The response of the medical communities to the plight of these injured claimants varied considerably from community to community. Denver represents one extreme where the clinical judgments led to multiple surgical interventions, generated a total direct cost of some $1.5 million, and left many permanently disabled workers in their wake. This analysis raises many reservations about the validity of the "cumulative trauma disorder" hypothesis and provides an object lesson in the potential for untoward outcomes from the premature introduction of clinical hypotheses into the arena of health policy.

    Full Text Available The South African government’s Strategic Arms Package (SAP, has beenthe largest public controversy of the post-Apartheid era. We synthesise the debatesabout two dimensions of the SAP, military necessity and affordability, in order toget a better understanding of civil-military relations in democratic South Africa. Oursynthesis shows that the economic enthusiasm about the SAP is both naïve and anopportunity for government and dominant business and industry to wed theirinterests in a way that is not that different from the Apartheid era. In military terms,the SAP has equipped the South African Air Force (SAAF and South African Navy(SAN for the most improbable of primary missions. The equipment is also not veryrelevant to secondary missions. The way that the SAP decisions were reachedsuggests that civil-military relations are marked by the continuing impact of pastcompromises, corruption and the centralisation of power in the executive branch.

  18. Physicists' Forced Migrations under Hitler

    Science.gov (United States)

    Beyerchen, Alan

    2011-03-01

    When the Nazis came to power in early 1933 they initiated formal and informal measures that forced Jews and political opponents from public institutions such as universities. Some physicists retired and others went into industry, but most emigrated. International communication and contact made emigration a viable option despite the desperate economic times in the Great Depression. Another wave of emigrations followed the annexation of Austria in 1938. Individual cases as well as general patterns of migration and adaptation to new environments will be examined in this presentation. One important result of the forced migrations was that many of the physicists expelled under Hitler played important roles in strengthening physics elsewhere, often on the Allied side in World War II.

  19. Gravitoinertial force background level affects adaptation to coriolis force perturbations of reaching movements

    Science.gov (United States)

    Lackner, J. R.; Dizio, P.

    1998-01-01

    We evaluated the combined effects on reaching movements of the transient, movement-dependent Coriolis forces and the static centrifugal forces generated in a rotating environment. Specifically, we assessed the effects of comparable Coriolis force perturbations in different static force backgrounds. Two groups of subjects made reaching movements toward a just-extinguished visual target before rotation began, during 10 rpm counterclockwise rotation, and after rotation ceased. One group was seated on the axis of rotation, the other 2.23 m away. The resultant of gravity and centrifugal force on the hand was 1.0 g for the on-center group during 10 rpm rotation, and 1.031 g for the off-center group because of the 0.25 g centrifugal force present. For both groups, rightward Coriolis forces, approximately 0.2 g peak, were generated during voluntary arm movements. The endpoints and paths of the initial per-rotation movements were deviated rightward for both groups by comparable amounts. Within 10 subsequent reaches, the on-center group regained baseline accuracy and straight-line paths; however, even after 40 movements the off-center group had not resumed baseline endpoint accuracy. Mirror-image aftereffects occurred when rotation stopped. These findings demonstrate that manual control is disrupted by transient Coriolis force perturbations and that adaptation can occur even in the absence of visual feedback. An increase, even a small one, in background force level above normal gravity does not affect the size of the reaching errors induced by Coriolis forces nor does it affect the rate of reacquiring straight reaching paths; however, it does hinder restoration of reaching accuracy.

  20. Dual Arm Work Module Development and Appplications

    Energy Technology Data Exchange (ETDEWEB)

    Noakes, M.W.

    1999-04-25

    The dual arm work module (DAWM) was developed at Oak Ridge National Laboratory (ORNL) by the Robotics Technology Development Program (RTDP) as a development test bed to study issues related to dual arm manipulation, including platform cotilguration, controls, automation, operations, and tooling. The original platform was based on two Schilling Titan II manipulators mounted to a 5-degree-of- freedom (DOF) base fabricated by RedZone Robotics, Inc. The 5-DOF articulation provided a center torso rotation, linear actuation to change the separation between the arms, and arm base rotation joints to provide "elbows up," elbows down," or "elbows out" orientation. A series of tests were conducted on operations, tooling, and task space scene analysis (TSSA)-driven robotics for overhead transporter- mounted and crane hook-deployed scenarios. A concept was developed for DAWM deployment from a large remote work vehicle, but the project was redirected to support dismantlement of the Chicago Pile #5 (CP-5) reactor at Argonne National Laboratory in fiscal year (FY) 1997. Support of CP-5 required a change in focus of the dual arm technology from that of a development test bed to a system focussed for a specific end user. ORNL teamed with the Idaho National Environmental ,Engineering Laboratory, Sandia National Laboratory, and the Savannah River Technology Center to deliver a crane-deployed derivative of the DAWM, designated the dual arm work platform (DAWP). RTDP staff supported DAWP at CP-5 for one FY; Argonne staff continued operation through to dismantlement of the reactor internals. Lessons learned from this interaction were extensive. Beginning in FY 1999, dual arm development activities are again being pursued in the context of those lessons learned. This paper describes the progression of philosophy of the DAWM from initial test bed to lessons learned through interaction at CP-5 and to the present investigation of telerobotic assist of teleoperation and TSSA- driven robotics.

    The measurement flights of the exercise ARM10 were performed between 5{sup th} and 8{sup th} of July 2010 under the direction of G. Scharding of the National Emergency Operations Centre (NAZ) and coordination by the Expert Group for Aeroradiometrics (FAR). According to the alternating schedule of the annual ARM exercises, the environs of the nuclear power plants Beznau (KKB) and Leibstadt (KKL) as well as those of the Paul Scherrer Institute (PSI) research facility and of the Intermediate Storage Facility for Nuclear Waste (ZWILAG) were inspected. In cooperation with German authorities the measuring area was extended with a region north of the Rhine river. The values measured over the premises of KKB, KKL, ZWILAG and PSI matched with the results obtained in previous years. On request by the Federal Office of Public Health (FOPH) areas near Posieux, Guettingen, Cadenazzo and Affoltern/ZH were inspected. These locations are intended as reference areas for the radiological surveillance of the environment by FOPH. In preparation of an international intercomparison exercise scheduled for 2011 in the field of in-situ gamma-spectrometry, an area located in the Dischma Valley was measured with airborne gamma-spectrometry. Measuring flights along three profiles supplemented aeroradiometric data in Swiss regions which were not covered before by airborne gamma-spectrometry.(authors)

  8. Repulsive casimir forces

    International Nuclear Information System (INIS)

    We discuss repulsive Casimir forces between dielectric materials with nontrivial magnetic susceptibility. It is shown that considerations based on the naive pairwise summation of van der Waals and Casimir-Polder forces may not only give an incorrect estimate of the magnitude of the total Casimir force but even the wrong sign of the force when materials with high dielectric and magnetic responses are involved. Indeed repulsive Casimir forces may be found in a large range of parameters, and we suggest that the effect may be realized in known materials. The phenomenon of repulsive Casimir forces may be of importance both for experimental study and for nanomachinery applications

  9. Strategies for redundancy resolution of dual-arm systems with passive elements for tank waste removal

    International Nuclear Information System (INIS)

    The work described in this paper focuses on the coordination and control of two manipulators coupled by passive elements operating in a confined space. An example of one such system is the hardware used for the environmental response treatability study funded by the Department of Energy at Oak Ridge National Laboratory (ORNL). The motivation for this project is to establish the methodology necessary to extract large volumes of hazardous waste from underground storage facilities. The hardware used at ORNL consists of two long-reach manipulators. The first robot, the Modified Light Duty Utility Arm (MLDUA), is an 8-degree-of-freedom long-reach manipulator. The second arm, the Hose Management Arm (HMA), has two active degrees-of-freedom and provides hardware to break up and extract materials from the tank. Current strategies call for the MLDUA to grasp a combined sluicing end-effector attached, by a long flexible hose, to the HMA. The MLDUA will then move the combined system through the waste, extracting material. This paper describes many of the issues related to redundancy resolution and the coordinated control of these two robots. First, the authors provide a brief outline of the project and the existing hardware. This is followed by a description of existing redundancy resolution techniques and the impact redundancy has on the success of the project. Finally, preliminary simulation results show the effect cooperative control has on the level of forces generated between the dual-arm systems when coupled by an elastic exhaust hose. These results show a significant reduction in forces when both arms are active and have a combined manipulation strategy

    The aim of the study was to compare the electromyographic activity of rectus abdominis, oblique external, and lower and upper erector spinae at both sides of the truncus in 1-armed and 2-armed kettlebell swing. Sixteen healthy men performed 10 repetitions of both exercises using a 16-kg kettlebell in randomized order. For the upper erector spinae, the activation of the contralateral side during 1-armed swing was 24% greater than that of the ipsilateral side during 1-armed swing (p kettlebell swing with 1 arm resulted in greater neuromuscular activity for the contralateral side of the upper erector spinae and ipsilateral side of the rectus abdominis, and lower activation of the opposite side of the respective muscles.

  12. Do Institutions Cause Growth?

    2004-01-01

    We revisit the debate over whether political institutions cause economic growth, or whether, alternatively, growth and human capital accumulation lead to institutional improvement. We find that most indicators of institutional quality used to establish the proposition that institutions cause growth are constructed to be conceptually unsuitable for that purpose. We also find that some of the instrumental variable techniques used in the literature are flawed. Basic OLS results, as well as a var...

    The quality of contracting institutions has been thought to be of second-order importance next to the impact that good property rights institutions can have on long- run growth. Using a large range of proxies for each type of institution, we find a robust $negative$ link between the quality of contracting institutions and long-run growth when we condition on property rights and a number of additional macroeconomic variables. Although the result remains something of a puzzle, we present eviden...

  14. Force propagation and force generation in cells.

    2010-09-01

    Determining how forces are produced by and propagated through the cytoskeleton (CSK) of the cell is of great interest as dynamic processes of the CSK are intimately correlated with many molecular signaling pathways. We are presenting a novel approach for integrating measurements on cell elasticity, transcellular force propagation, and cellular force generation to obtain a comprehensive description of dynamic and mechanical properties of the CSK under force loading. This approach uses a combination of scanning force microscopy (SFM) and Total Internal Reflection Fluorescence (TIRF) microscopy. We apply well-defined loading schemes onto the apical cell membrane of fibroblasts using the SFM and simultaneously use TIRF microscopy to image the topography of the basal cell membrane. The locally distinct changes of shape and depth of the cytoskeletal imprints onto the basal membrane are interpreted as results of force propagation through the cytoplasm. This observation provides evidence for the tensegrity model and demonstrates the usefulness of our approach that does not depend on potentially disturbing marker compounds. We confirm that the actin network greatly determines cell stiffness and represents the substrate that mediates force transduction through the cytoplasm of the cell. The latter is an essential feature of tensegrity. Most importantly, our new finding that, both intact actin and microtubule networks are required for enabling the cell to produce work, can only be understood within the framework of the tensegrity model. We also provide, for the first time, a direct measurement of the cell's mechanical power output under compression at two femtowatts. PMID:20607861

  15. On the forced flow around a flapping foil

    CERN Document Server

    Mandujano, Francisco

    2016-01-01

    The two dimensional incompressible viscous flow past a flapping foil immersed in a uniform stream is studied numerically. Numerical simulations were performed using a Lattice-Boltzmann model for moderate Reynolds numbers. The computation of the hydrodynamic force on the foil is related to the the wake structure. In particular, when the foil's centre of mass is fixed in space, numerical results suggest a relation between drag coefficient behaviour and the flapping frequency which determines the transition from the von K\\'arm\\'an (vKm) to the inverted von K\\'arm\\'an wake. Beyond the inverted vKm transition the foil was released. Upstream swimming was observed at high enough flapping frequencies. Computed hydrodynamic forces suggest the propulsion mechanism for the swimming foil.

  17. Understanding and Improving CRM and GCM Simulations of Cloud Systems with ARM Observations

    Wu, Xiaoqing

    2014-02-25

    The works supported by this ASR project lay the solid foundation for improving the parameterization of convection and clouds in the NCAR CCSM and the climate simulations. We have made a significant use of CRM simulations and ARM observations to produce thermodynamically and dynamically consistent multi-year cloud and radiative properties; improve the GCM simulations of convection, clouds and radiative heating rate and fluxes using the ARM observations and CRM simulations; and understand the seasonal and annual variation of cloud systems and their impacts on climate mean state and variability. We conducted multi-year simulations over the ARM SGP site using the CRM with multi-year ARM forcing data. The statistics of cloud and radiative properties from the long-term CRM simulations were compared and validated with the ARM measurements and value added products (VAP). We evaluated the multi-year climate simulations produced by the GCM with the modified convection scheme. We used multi-year ARM observations and CRM simulations to validate and further improve the trigger condition and revised closure assumption in NCAR GCM simulations that demonstrate the improvement of climate mean state and variability. We combined the improved convection scheme with the mosaic treatment of subgrid cloud distributions in the radiation scheme of the GCM. The mosaic treatment of cloud distributions has been implemented in the GCM with the original convection scheme and enables the use of more realistic cloud amounts as well as cloud water contents in producing net radiative fluxes closer to observations. A physics-based latent heat (LH) retrieval algorithm was developed by parameterizing the physical linkages of observed hydrometeor profiles of cloud and precipitation to the major processes related to the phase change of atmospheric water.

  18. Forces in general relativity

    International Nuclear Information System (INIS)

    Many textbooks dealing with general relativity do not demonstrate the derivation of forces in enough detail. The analyses presented herein demonstrate straightforward methods for computing forces by way of general relativity. Covariant divergence of the stress-energy-momentum tensor is used to derive a general expression of the force experienced by an observer in general coordinates. The general force is then applied to the local co-moving coordinate system of a uniformly accelerating observer, leading to an expression of the inertial force experienced by the observer. Next, applying the general force in Schwarzschild coordinates is shown to lead to familiar expressions of the gravitational force. As a more complex demonstration, the general force is applied to an observer in Boyer-Lindquist coordinates near a rotating, Kerr black hole. It is then shown that when the angular momentum of the black hole goes to zero, the force on the observer reduces to the force on an observer held stationary in Schwarzschild coordinates. As a final consideration, the force on an observer moving in rotating coordinates is derived. Expressing the force in terms of Christoffel symbols in rotating coordinates leads to familiar expressions of the centrifugal and Coriolis forces on the observer. It is envisioned that the techniques presented herein will be most useful to graduate level students, as well as those undergraduate students having experience with general relativity and tensor analysis.

    2014-01-01

    There is evidence that the distribution of suspected cosmic ray sources are associated with the spiral arm structure of galaxies. It is yet not clearly understood what effect such a cosmic ray source distribution has on the particle transport in our Galaxy. We use the PICARD code to perform high-resolution 3D simulations of electrons and protons in galactic propagation scenarios that include four-arm and two-arm logarithmic spiral cosmic ray source distributions with and without a central bar structure as well as the spiral arm configuration of the NE2001 model for the distribution of free electrons in the Milky Way. Results of these simulation are compared to an axisymmetric radial source distribution. Also, effects on the cosmic ray flux and spectra due to different positions of the Earth relative to the spiral structure are studied. We find that high energy electrons are strongly confined to their sources and the obtained spectra largely depend on the Earth's position relative to the spiral arms. Similar f...

    Over the last twenty years piracy has become an increasing threat. Yet there are only very few econometric studies that examine under which conditions this phenomenon arises. As the number of maritime piracy and armed robbery incidents is characterized as count data and exhibits overdispersion, we apply random-effects negative binomial regressions for a panel dataset covering the period 1991-2010. Our results indicate that poor socio-economic, political, and institutional conditions in the ho...
