Introduction: High heel shoes affect the knee joint and can cause arthritis in the tibiofemoral (TFJ) and patellofemoral joints (PFJ). There is a dearth of research investigating the contact forces of TFJ and PFJ. Therefore, the purpose of this study was to assess the effect of high heel shoes on muscle forces as well as TFJ, and PFJ contact forces during walking. Materials & Methods: A tot...
Similar to random sea waves, forces on the offshore structures due to waves are random. These forces can be mainly divided into two components, namely, inline forces and transverse or lift forces. The random nature of lift forces is more complicated than that of inline forces and both should be combined for design purposes. In the present paper, two different approaches have been used to determ...
This paper presents a longitudinal study (over 4 months) of an A&E department where the existing whiteboards were replaced with PC-based computer systems. The study was conducted in two parts - an observation of the physical whiteboard usage and in-depth interviews with all users of both the traditional whiteboard usage and the replacement technology. The research was conducted with the systems...
Text summarization is an important activity in the analysis of a high volume text documents. Text summarization has number of applications; recently number of applications uses text summarization for the betterment of the text analysis and knowledge representation. In this paper a frequent term based text summarization algorithm is designed and implemented in java. The designed algorithm works ...
When the eye is exposed to intermittent light a sensation of flicker is produced, which, however, disappears at a certain critical frequency of intermittence, and this is known as the critical fusion frequency (CFF) . The dependence of CFF on the intensity of illumination has extensively been investigated by a number of workers"-13). If the CFF is plotted as ordinates against the logarithm of i...
Tourism has been emphasized as one of the main sources foreign exchange for different economies in world, whereas most developing countries recognized hospitality, Travel, and an inspiring element socio-economic prosperity. Within previous decades, tourism satisfaction or “choice destinations” were gradually transformed towards segments a paradigm shift. The nature provides pathway on developme...
I n the classic revenue management (RM) problem of selling a fixed quantity of perishable inventories to price-sensitive non-strategic consumers over a finite horizon, the optimal pricing decision at any time depends on two important factors: consumer valuation and bid price. The former is determined exogenously by the demand side, while the latter is determined jointly by the inventory level o...
