Flies are among the most agile of flying insects, a capacity that ultimately results from their nervous system's control over steering muscles and aerodynamic forces during flight. In order to investigate the relationships among neuromuscular control, musculo-skeletal mechanics and flight forces, we captured high-speed, three-dimensional wing kinematics of the blowfly, Calliphora vicina, while ...

Anesthetized swine were tested for biomechanical and injury responses to lower abdominal steering wheel loading. The lower abdomens of 25 subjects were impacted with a segmented steering wheel. Tests included a wide spectrum of velocities, from 1.7 to 12.4 m/s, and forced abdominal compressions of 7.0%-54.5% of the vertical thickness of the lower abdomen. Lower abdominal injuries included contu...

Trajectory-based tasks are common in many applications and have been widely studied. Recently, researchers have shown that even very simple tasks, such as selecting items from cascading menus, can benefit from hapticforce guidance. Haptic guidance is also of significant value in many applications such as medical training, handwriting learning, and in applications requiring precise manipulations...

OBJECTIVES To perform a systematic literature review of effective strategies for the treatment of rheumatoid arthritis (RA). METHODS As part of a European League Against Rheumatism (EULAR) Task Force investigation, a literature search was carried out from January 1962 until February 2009 in PubMed/Ovid Embase/Cochrane and EULAR/American College of Rheumatism (ACR)) abstracts (2007/2008) for s...

in this study, a three wheel dynamic model refer to a field tractor with an implement was developed to control the tractor in the field accurately. main difference between a tractor and in-road vehicles is implements connected to the tractor. these implements exert lateral and draft force to the tractor. in order to investigate these kinds of forces, behavior of implements was simulated like a ...

This paper presents an efficient shape-based three-axial force and stiffness estimator for active catheters commonly implemented in cardiac ablation. The force-sensing capability provides important feedback for catheterization procedures including real-time control and catheter steering in autonomous navigation systems. The proposed platform is based on the introduced accurate and computational...

In recent years, with the development of photovoltaic system and photo-thermal system technology, hybrid photovoltaic-thermal (PVT) technology has been a breakthrough in many aspects. This paper describes the movable hybrid PVT system from the aspects of appearance structure, energy flow, and control circuit. The system is equipped with rolling wheels and the simulated light sources also can be...

e43 Since the 2005 publication of the first “Training Guidelines for Pediatric Cardiology Fellowship Programs,” the field of pediatric cardiology has undergone significant growth and change, and thus, the Society of Pediatric Cardiology Training Program Directors (SPCTPD) in conjunction with the Joint Council of Congenital Heart Disease recommended the guidelines be revised accordingly. The SPC...
