A logarithmic formulation for anisotropic behavior characterization of bovine cortical bone tissue in long bones undergoing uniaxial compression at different speeds

The mechanical properties of bone tissues change significantly within the bone body, since it is considered as a heterogeneous material. The characterization of bone mechanical properties is necessary for many studies, such as in prosthesis design. An experimental uniaxial compression study is carried out in this work on bovine cortical bone tissue in long bones (femur and tibia) at several speeds

Effect of thickness and temperature on flexible organic P3HT:PCBM solar cell performance

A blend of poly 3-hexylthiophene (P3HT) and [6, 6]-phenyl-C61-butyric acid methyl ester (PCBM) is used as a photoactive layer for simulating a bulk heterojunction organic solar using general-purpose photovoltaic device model (GPVDM) software. The optical and electrical performance of the cell had been analyzed by changing the thickness of each layer and substrate material over a range of operating

Enhancing barrier properties of chitosan extracted from shrimp shells as a sustainable material for active packaging using natural wastes

Due to the environmental concerns, much responsiveness has been paid to natural polymers and recycle wastes. Disposal of wastes like marine wastes and domestic wastes end up in landfills and open areas which cause environmental crisis. The development of biodegradable active packaging materials is one of the alternatives to reduce the using of synthetic petroleum-based plastics. Biodegradable

Stabilized variational formulation of an oldroyd-B fluid flow equations on a Graphic Processing Unit (GPU) architecture

The governing equations of the flow of an oldroyd-B fluid are discretized using the finite element method. To overcome the convective nature of the momentum equation, the Galerkin/Least-Squares Finite Element Method (GLS/FEM) is used while the Discrete Elastic–Viscous Stress-Splitting (DEVSS) method is used to overcome the instability due to the absence of diffusion in the constitutive equations

A switched chaotic encryption scheme using multi-mode generalized modified transition map

This paper presents a multi-mode generalized modified transition chaotic map and a switched chaotic encryption scheme based on it. Eight different modes of operation can be selected based on the map graph (concave or convex), the range modification procedure (shrinking or widening) and the sign of one of its independent parameters. The generalization and modification preserve the controllability

A queueing theory approach to traffic offloading in heterogeneous cellular networks

Future and current cellular networks encounter an unprecedented growth of mobile devices traffic, imposing various critical challenges that should be thoroughly addressed. Catering for such enormous amount of traffic demand via cellular networks significantly increases the network congestion and degrades the achievable quality of service (QoS). Thus, traffic offloading has been suggested to tackle

Develop TE/TM Pass Filters on double-loaded-on-ridge Structure with ITO/TiN for Upstream FTTH Optical Access Networks

In this paper, TE/TM pass filters are introduced as a dual optical multiplexer in the fiber-to-the home (FTTH) uplink transmission. The architecture is implemented at 1330 nm wavelength, with a double-loaded-on-ridge structure. In the TE pass filter, TM mode couples with plasmonic mode while TE mode is guided through the core with low losses due to the effect of the two plasmonic materials. The TM
