investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
We tested the hypothesis that dominant and nondominant overarm throws of different speeds are made by time-scaling of joint rotations, i.e., by joint rotations that have the same positions and amplitudes but that are scaled in time. Eight skilled subjects stood and made overarm throws with both their dominant and nondominant arms. Six joint rotations were computed from recordings of arm segment...
In this work, we define the joint normal eigenvalue, joint reducing approximate eigenvalue and we obtain some important and new results about the boundary of joint numerical range of n-tuple operators on a complex Hilbert space.
Comparable conventional x-rays had xeroradiographs were obtained of the hands of 22 patients with rheumatoid arthritis. Each metacarpophalangeal and proximal interphalangeal joint was scored for juxta-articular osteoporosis, erosions, loss of joint space, soft tissue thickening, joint deformity, and osteophytes on a 0-3 scale. For 10 hands the films were reported again after 3 months, and each ...
Background : Septic Arthritis is an acute infection of intra-arthicular space. Delay in diagnosis and in appropriate treatment may lead to prolongation of treatment duration and poor outcome. We decided to evaluate clinical aspects of this disease in our department pediatric department, Imam Khomeini Hospital complex, Tehran, Iran during a 10 years period. Methods : In a retrospective cross-sec...
Space robots are an effective resource for astronauts working in a dangerous space environment. This paper proposes and implements a system to validate the performance of robot movement in space. A humanoid robot was designed with a vision-based self-calibration and navigation system. In addition, a path planning method was proposed to minimize joint torque. Simple gravity-compensation equipmen...
Any section or space in architecture that connects other sections or spaces called a joint. This research proposes using the word "Articulation" instead "Joint", on the basis of the etymology of both words. So in this abstract, the concept of "joint" is meant anywhere the word "Articulation" is mentioned. The present research deals with theoretical aspects of architecture. Its primary goal is t...
