P. K. Saha, F. W. Wehrli University of Pennsylvania, Philadelphia, PA 19104, United States SYNOPSIS: Trabecular bone (TB) is a network of interconnected struts and plates. During remodeling the bone responds to the forces to which it is subjected and the trabeculae thus follow major stress lines (Wolff’s law). Trabecular anisotropy can be expressed in terms of the fabric tensor. Next to volume ...

Nanofluid is prepared through the nanoscale particles suspended in a fluid base and Nanotechnology is a new attempt to investigate the thermal sciences. As a result of huge investment in developed countries on nanotechnology, research on thermal properties of nano-fluids is of particular interest.Due to the usage of nanotechnology to reduce energy waste, in this project CeO2 with EG is used to ...

Computers are physical systems: what they can and cannot do is dictated by the laws of physics (1-23). In particular, the speed with which a physical device can process information is limited by its energy (24-27), and the amount of information that it can process is limited by the number of degrees of freedom it possesses (1-2). The way in which it processes information is determined by the fo...

The paper deals with the presence of exponential or power-law decay in the power spectra of electroencephalogram (EEG). About 2300 EEG time series recorded during relaxed wakefulness were analysed. The whole spectrum of EEG was studied and power-law decay of about 2.28 prevailing over the exponential falling off was established. Correspondence between spectrum power-law decay and correlation di...

in this paper, the effect of autofrettage process parameters on the ultimate pressure that functionally graded spherical vessel can tolerate are investigated. fgm properties and autofrettage pressure are considered as important parameters. assumptions are variation of properties of fgm in radial direction, the residual stress in the absence of bauschinger effect with the operation of variable m...

Using conductive nanocomposites for bipolar plates in fuel cells can improve their performance. Percolation is the mechanism for nanocomposite conductivity. When the volume fraction of fillers in a composite material reaches a critical value, percolation starts to happen. If the composite material has an infinitesize, the probability of conductivity jumps from zero to 100% at the critical volum...

In the present paper, the effect of water-CuO nanofluid on the radiator heat transfer of an automobile, Peugeot 405 XU7 engine type is investigated experimentally. The experiments are carried out for the radiator water (water-ethylene glycol with a volume fraction of 80-20, respectively) as a base fluid and water-CuO nanofluid with the volume fraction of 0.5% and 1%. Sodium Dodecyl Sulfate (SDS...
