In this paper, the heat transfer to the fluid, passing through the double forward facing step (FFS) channel with square obstacle is enhanced by Taguchi’s S/N ratio analysis. Flow through the forward facing step channel has a wide range of applications in thermal systems due to its flow separation and subsequent reattachment, which in turn enhances the heat transfer. Flow separation and reattach...

In a walking cycle design, maximizing the upright balance should be considered in addition to the kinematic constraints, energy consumption rate must be considered. The purpose of this study is to find the optimal step length obtained for each person according to the physical features. In this research, in order to minimize energy consumption rate by considering maximum balance two cost functio...

Many researchers, up to now, have modeled the biped walking by considering the height of Center of Mass (CoM) as a fixed constant, other biomechanical studies show that the CoM height is variant during walking and running[1]. The shape of CoM height trajectory is important for energy consumption, and it varies differently for various speeds and step length ranges [2]. Although linear inverted p...

abstract the usage of heroin is associated with a variety of neurologic disorders, including acute transverse myelitis. in this study we present a 19 year old man who was suffered from insufflated heroin after several months of abstinence, and admitted to hospital emergency department, unconscious. he responded to fluid therapy and naloxone, but could not move his legs on examination. he had fl...

The continuous-space Schr\"odinger equation is mapped to the transverse Ising model while achieving an exponential advantage over classical computers: A step closer efficient simulation of multi-particle systems.

The objective of this study was to investigate the possibility of a generic rating curve with a small number of adjustable parameters for the restricted class of bedrock step-pool rivers. The motivation for this study arose from Utah Valley University’s long-term program of groundwater development in the Trans-Mexican Volcanic Belt, which requires hydrographs for bedrock step-pool rivers near r...

BACKGROUND The management of distal radial fractures is guided by the interpretation of radiographic findings. The aim of this investigation was to determine the intra- and inter-observer reliability of eight traditionally reported anatomic radiographic parameters in adults with an acute distal radius fracture. METHODS Five observers participated. All were routinely involved in making treatme...

The morphological instabilities of vicinal Si(111) due to a DC electric current and due to the 7 x 7 reconstruction are studied using a variety of diffraction and imaging techniques. The current induced instabilities which occur at sublimation temperatures or under conditions of step-flow produce morphological features on length scales appropriate for optical studies, 5 50,u. Optical microscopy...

PURPOSE To investigate the association between medial tibial stress syndrome (MTSS) and morphology and flexibility of the foot arches. METHODS 131 feet from 74 healthy subjects and 31 feet from 27 patients with MTSS were classified as normal feet (n=78 in 40 subjects), flat feet (n=53 in 34 subjects), or MTSS feet (n=31 in 27 patients). The medial longitudinal arch (MLA) ratio and the transve...

In spectral domain optical coherence tomography (SD-OCT), any transverse motion component of a detected obliquely moving sample results in a nonlinear relationship between the Doppler phase shift and the axial sample velocity restricting phase-resolved Doppler OCT (PR-DOCT). The size of the deviation from the linear relation depends on the amount of the transverse velocity component, given by t...
