The lower frequency rQ 2-branch of the torsional split rotational spectrum of H OO H has been recorded for the first time near 1.05 THz with Doppler limited resolution employing a Backward Wave Oscillator as the radiation source. The position of the Q-branch lines can be predicted very closely from a set o f effective rotational constants derived individually for the two torsionally split level...

This paper presents a method for reducing warping normal stresses in torsionally loaded I-section members by utilizing carbon fiber-reinforced polymer (CFRP) plates. The CFRP plates are bonded to the outer surfaces of flanges with view stresses. maximum stress steel I-shaped member without is compared those obtained having various thicknesses. It has been found that use both result substantial ...

We present a new strategy for solving stiff ODEs with explicit methods. By adaptively taking a small number of stabilizing small explicit time steps when necessary, a stiff ODE system can be stabilized enough to allow for time steps much larger than what is indicated by classical stability analysis. For many stiff problems the cost of the stabilizing small time steps is small, so the improvemen...

Here, we present a truly second order time accurate self-consistent IMEX (IMplicit/EXplicit) method for solving the Euler equations that posses strong nonlinear heat conduction and very stiff source terms (Radiation hydrodynamics). This study essentially summarizes our previous and current research related to this subject (Kadioglu & Knoll, 2010; 2011; Kadioglu, Knoll & Lowrie, 2010; Kadioglu, ...

PURPOSE In order to identify predictors for hand stiffness following distal radius fractures and understand the consequences of this common clinical finding, we studied 260 patients. Our null hypothesis was that we would find no predictors of post injury hand stiffness. METHODS Baseline demographics and injury characteristics were obtained at distal radius fracture presentation. Treatment and...

Stiff-knee gait is a movement abnormality in which knee flexion during swing phase is significantly diminished. This study investigates the relationships between knee flexion velocity at toe-off, joint moments during swing phase and double support, and improvements in stiff-knee gait following rectus femoris transfer surgery in subjects with cerebral palsy. Forty subjects who underwent a rectus...
