This paper examines differences in performances of a range of torsionally stiff and flexible single story buildings designed with the provisions of Iranian Standard 2800. Seismic nonlinear dynamic time history behavior of eight building models subjected to seven horizontal bi-directional design spectra compatible ground motions are investigated. These models cover a wide range of very torsional...

STUDY DESIGN Spine loads associated with lifting a 9-kg weight were estimated at three torso flexion angles (0 degrees, 22.5 degrees, and 45 degrees), and lumbosacral motion segments were cyclically loaded using these loads until failure or to a maximum of 10,020 cycles. OBJECTIVES To simulate the postures and loads experienced by the lumbar spine during repetitive lifting of moderate weights...

This paper is concerned with the parallel solution of the Bidomain equations and an associated forward problem, which can be used to simulate the electrical activity in the heart and torso. For achieving high-resolution simulations on parallel computers, a scalable and parallelizable numerical strategy must be used. We present therefore an advanced parallel preconditioner for a 2 × 2 block line...

A motion system collected 120-Hz data from 14 baseball adult hitters using normal and choke-up bat grips. Six swings were digitized for each hitter, and temporal and kinematic parameters were calculated. Compared with a normal grip, the choke-up grip resulted in 1) less time during stride phase and swing; 2) the upper torso more opened at lead foot contact; 3) the pelvis more closed and less ba...

To retrospectively determine the proportion of prostate cancer patients who are appropriate candidates for prostate localization with Calypso (Calypso Medical, Seattle, WA); to assess the accuracy of surface anatomy in predicting prostate depth; and to describe a simple clinical algorithm predicting patient's appropriateness for Calypso localization. Medical records and archived CT scans of all...

It was the purpose of our study to examine the kinematics of the pelvis and torso and determine their relationship to the kinematics of the shoulder in high-school baseball pitchers. A single group, repeated-measures design was used to collect pelvis, torso, and shoulder kinematics throughout the pitching motion. Subjects threw a series of maximal effort fastballs to a catcher located the regul...

Forward-problem solutions were approximated using spherical-harmonic series on an adult male torso model with heart and lungs. These approximations were found using only a knowledge of torso-model geometry and were not based on a prior solution for surface potentials. Because these series depend only on polar and azimuthal angles, they allow continuous estimation of the forward-problem solution...

Incontinentia pigmenti (Bloch-Sulzberger syndrome) is a genetic disease of the skin with generalised ectodermal and mesodermal dysplasia which may often involve the eyes (35% of the patients),' hair, teeth, and central nervous system. Skin lesions are Correspondence to Dr A Spallone. usually present at birth or shortly after in the form of erythematous eruptions with linear vesiculations. The f...

An artificial torso is a fundamental part of a humanoid robot for imitating human actions. In this paper, a prototype of CAUTO (CAssino hUmanoid TOrso) is presented. Its design is characterized by artificial vertebras actuated by cable-driven parallel manipulators. The design was conceived by looking at the complex system and functioning of the human torso, in order to develop a solution for ba...
