The optimal architecture of personal digital assistants (PDA) system for real-time 3D graphics was analyzed by simulating the 3D applications on the various Advanced RISC Machines (ARM) processor platforms. Simulation results show that for 256x256 screen resolution, even the performance of 200MHz StrongARM with 160MHz floating point unit (FPU) shows only 1.78 % of the requirement of full 3D pip...

This article presents impact dynamic analysis of a free-floating space robot, subject to a force impulse at the hand. We study the joint and the base reactions in terms of finite velocity changes and clarify their role for the post-impact motion behavior of the robot. The analysis makes use of a jointspace orthogonal decomposition procedure involving the so called reaction null space. The artic...

This report presents a therapeutic procedure for refractory benign paroxysmal positional vertigo (antBPPV) of the anterior canal. Two patients with refractory antBPPV were treated by a prolonged forced position procedure (PFPP). The technique is based on the assumption that the pathophysiological mechanism of antBPPV is similar to that generating posterior canal canalolithiasis. The patients re...

INTRODUCTION Simultaneous supracondylar humerus fracture and ipsilateral fracture of the proximal humerus in children is rare. CASE PRESENTATION A 10-year-old Turkish boy with an extension type supracondylar humerus fracture and ipsilateral fracture at the proximal metaphyseal-diaphyseal junction of the humerus was treated by closed reduction and percutaneous Kirschner wire fixation. Closed r...

kaposiform hemangioendothelioma is an aggressive endothelial-derived spindle cell neoplasm that occurs nearly exclusively during childhood and teenage years. the lesion grows rapidly and is often associated with kasabach-merritt syndrome. in this study a 24 days old male neonate who presented with an ill-defined deeply situated violaceous mass on his left arm is described. he had also anemia an...

Radial head fractures are the most common type of elbow fracture in adults. Unrecognised disruption of the intraosseous membrane at the time of injury can lead to severe wrist pain from proximal radial migration especially if the radial head is excised. In this case, despite anatomical reduction and internal fixation of the radial head fracture, longitudinal forearm instability developed after ...

NASA is preparing a giant gravity wave observatory that will be placed in space. The Laser Interferometer Space Antenna (LISA) consists of three spacecraft forming a equilateral triangle with 5 million km armlength. Changes in the armlength of 20pm will be detected. The ends of each interferometer arm are formed by freely floating masses that must be kept inertial (i.e. free of non-gravitationa...

In space application, it is of great interest the development of autonomous or semi-autonomous robotic devices that can substitute the astronauts in routine operations in order to free them from repetitive tasks and reduce mission costs. In this work, an experimental setup based on a 6 degrees of freedom (dof) manipulator with a 3 dof gripper designed for a possible application within PaT, the ...

This demonstration introduces the Stride programming language, the Stride IDE, and the Saturn M7 embedded audio development board. Stride is a declarative and reactive domain specific programming language for real-time sound synthesis, processing, and interaction design. The Stride IDE is a cross-platform integrated development environment for Stride. Saturn M7 is an embedded audio development ...
