the purpose of this study is to improve the aerodynamic performance of wind turbine blades, using the ball-spine inverse design method. the inverse design goal is to calculate a geometry corresponds to a given pressure distribution on its boundaries. by calculating the difference between the current and target pressure distributions, geometric boundaries are modified so that the pressure differ...

Objective: Flexed posture students who had hyperkyphosis (HKP) and forward head posture (FHP) due to changes in the spine alignment leads to displacement of the center of pressure and increased postural sways which ultimately disrupts the distribution of foot pressure. Therefore, the aim of this study was to compare the effect of eight weeks of National Academy of Sports Medicine (NASM) and Sha...

Designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied Together with design and build a low-speed wind tunnel. A specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. There are generally three regi...

Water is the most essential component for sustaining lives of humans and other living creatures. Supplying potable water with adequate residual pressure is a fundamental responsibility of city administration, which they do during normal conditions. But sometimes, abnormal conditions are formed resulting pressure deficient conditions during the daily operations of water distribution networks. Th...

The pressure distribution was measured for subjects sitting on a flat, hard and horizontal support. The pressure data were analyzed for the seat force, the magnitude of the contact area, the average pressure in the contact area, the maximum pressure, and the pressure gradient. Using multiple regression relationships were found between these pressure distribution parameters, the body characteris...

 Integral bridges are gaining increased popularity because of both economic and fast construction associated with the omission of bearing supports and expansion joints. In the present study the cyclic earth pressure behind integral bridge abutments under traffic surcharges are investigated and compared with that induced behind the abutment of  conventional bridges (with isolated deck and abutme...

• The ejection of blood into the root of the aorta by the heart produces pressure changes which are transmitted peripherally through the vascular bed. The propagation of these pressure waves has been a topic of interest and conjecture for a number of years because of its importance in the study of the physical properties and energetics of the vascular bed. As a result many data have accumulated...

One challenge in multimodal interface research is the lack of robust subsystems that support multimodal interactions. By focusing on a chair—an object that is involved in virtually all human–computer interactions, the sensing chair project enables an ordinary office chair to become aware of its occupant’s actions and needs. Surface-mounted pressure distribution sensors are placed over the seatp...
