Mechanical testing of the Re-Flex VSP Foot was conducted on the pylon alone and on the pylon and forefoot system. Values for spring and damping correspond well to values reported in the literature for spring and damping of physiological limbs. Pylon stiffness was 49.4 kN/m for a 600 N subject and 91.4 kN/m for an 800 N subject. The vertical stiffness of the pylon and forefoot together was 31.9 ...
BACKGROUND Double eyelidplasty can construct palpebral folds and enhance beauty perception for Asians with single eyelids. A new palpebral parameter for the quantitative interpretation of surgical outcomes is proposed on the basis of a photometric study of the altered proportions of Asian eyes after double eyelid operation. METHODS A total of 100 Asian adults with single upper eyelids who wer...
Correlations between geophysical parameters and tropical cyclones are essential in understanding and predicting the formation of tropical cyclones. Previous studies show that sea surface temperature and vertical wind shear significantly influence the formation and frequent changes of tropical cyclones. This paper presents the utilization of a new approach, data mining, to discover the collectiv...
Increasing consumer demand for access to services anywhere and anytime is driving a hastened technological progression towards the integration of a variety of wireless access technologies. Therefore one of the chief interest points of Next Generation Wireless Networks (NGWNs), refers to the capability to support wireless network access equipments to guarantee a high rate of services between dis...
The "vertical drop Structure" is one of the basic types used in channel system flow. Drops are used as slope breakers in some parts of channels where we encounter supercritical slopes. Scour is a dynamic phenomenon that is visible in vertical drop tail water depth. Because of complexity of Scour process and simultaneous testing of variables’ effective compliance, studies are still underway to d...
At CesrTA, we have developed the capability to make automated measurements of the self-excited frequency spectra of individual bunches, to look for signals for singlebunch instabilities. We can also drive single bunches and measure the rate of decay of selected lines in their frequency spectra. We have used these capabilities to explore the dynamics of the interaction of a multi-bunch beam with...
Currently, to ensure seamless roam across heterogeneous wireless technologies, efficient vertical handoff algorithms are required to enhance QoS and offer reliable pervasive computing environment. This study reviews traditional and classical artificial intelligent approaches adopted for vertical handoff across heterogeneous networks. A type-2 fuzzy multi-parameter based vertical handoff decisio...
The present study was designed to investigate the determination of vertical jumping height by means of force plate measurements. Four different sources of error influence this determination: the measurement of body mass, the determination of take off, the integration frequency, and the assessment of the initial conditions influencing the determination of the start of the movement. A theoretical...
background and aims. plasma rich in growth factors (prgf) is a concentrated suspension of growth factors, which is used to promote periodontal tissue regeneration. the aim of this randomized, controlled, clinical trial was to evaluate of the treatment of grade ii mandibular molar furcation involvement using autogenous bone graft with and without prgf. materials and methods. in this double-blind...
Transmission of blast waves is a complex phenomenon and the characteristics vary with blast design parameters and geo-technical properties of medium. Frequency of vibration and triggering component for structural excitation generally quantifies safe vibration magnitude. At closer distance or higher elevations than the blast locations, vertical or transverse component will be the first arrival t...
