This paper describes the simulation of movement control of a one-degree-of-freedom articulated robot arm SCARA actuated by a pair of McKibben pneumatic artificial muscles. The pneumatic artificial muscle is the actuator and emulates the behavior of biological muscles; due to its nonlinear behavior, there is also a need to develop control systems for robot(More)
Fernando J. Escobar received his B.S. Mathematics and M.S. Physics from Utah State University, Logan, Utah. From 1989-1998, he worked in the Research Department of the Naval Air Warfare Center Weapons Division developing algorithms for EM scattering problems. He is currently with the GPS & Navigation System Research Group at SPAWAR Systems Center, San(More)
Like the field of geography, the term Geographic Information System (GIS) is hard to define. It represents the integration of many subject areas. Accordingly there us no absolutely agreed upon definition of a GIS (deMers, 1997). A broadly accepted definition of GIS is the one provided by the National Centre of Geographic Information and Analysis: a GIS is a(More)
This paper presents an algorithm of simultaneous localization and mapping (SLAM) with a scanning laser range finder and radiofrequency identification technology (RFID) to include landmarks of an object or place within a generated map. For the testing phase was used of simulation software Anykode’s Marilou and was used to build a virtual mobile robot with(More)
The effectiveness of eicatonin was assessed in a prospective study of patients with a diagnosis of postmenopausal/senile osteoporosis. In the first stage, 521 patients (490 women [mean time since menopause, 14.4 years] and 31 men; mean age, 61.4 years) with clinical evidence of osteoporosis were recruited. Bone mineral density (BMD) was measured in 486 of(More)
The inherent complexity in utilizing and programming high performance computing (HPC) systems is the main obstacle to widespread exploitation of HPC resources and technologies in the Department of Defense (DoD). Consequently, there is the persistent need to simplify the programming interface for the generic user. This need is particularly acute in the(More)
