In engineering applications, especially in the field of modern military defence, the cylindrical shells, conical shells and coupled conical-cylindrical shells are basically simplified models of many types of weapons and equipment, such as aircraft, missiles, and submarines. The study of free vibrational characteristics of cylindrical shells is comprehensive. Initially, researchers1-5 investigat...

Abstract: The off-shell statistical-mechanical entropy for a massless scalar field in a D-dimensional Rindler-like space-time is investigated within the conical Euclidean approach in the manifold Cβ × MN , Cβ being the 2-dimensional cone, making use of the zeta-function regularisation. Due to the presence of conical singularities, it is shown that the relation between the zeta-function and the ...

With dramatic increase in 3D printing applications industry, sandwich panels with printed cores have gained a lot of attention recently. In harmony global movement towards sustainability and low-carbon emission industries, easy-to-repair cost-effective would be very attractive structures. this regard, implementing separated cells for constructing lattice structures instead using back-to-back ma...

The three-dimensional structure of TNF has been determined at 0.29 nm using the technique of X-ray crystallography. Published data on site-directed mutagenesis and antibody binding may now be assessed in the light of the structure, thus the links between structure and function for TNF may be addressed. TNF is a compact trimer composed of three identical subunits of 157 amino acids. The main-cha...

We describe computational modeling of flaring horns and piecewise conical bores using “Truncated Infinite Impulse Response” (TIIR) digital filtering techniques. The approach yields highly efficient and accurate computational models and is therefore appropriate for real-time simulations of woodwind and brass musical instruments.
