V-band clamps offer an efficient clamping solution in diverse applications including process equipment, exhaust systems and air handling. This paper studies the distribution of interface contact pressure between the V-band and flange when the coupling is established. The determination of the contact area and pressure distribution in a joint is essential information, as it determines the integri...

In this paper, a channel drop ring resonator filter based on two dimensional photonic crystal is proposed which is suitable for all optical communication systems. The multilayer of silicon rods in the center of resonant ring enables one to adjust resonant wavelength of the ring and enhance power coupling efficiency between ring and waveguide. Refractive index and radius of multilayer rods insid...

This study introduces the Differential Transform Method (DTM) in the analysis of the free vibration response of a rotating closed section composite, Timoshenko beam, which features material coupling between flapwise bending and torsional vibrations due to ply orientation. The governing differential equations of motion are derived using Hamilton’s principle and solved by applying DTM. The natura...

In this paper Kolomogorov entropy of a simulated cavity quantum electrodynamics in a multi-partite system consisting of eight quantum dots in interaction with one cavity mode has been estimated. It has been shown that the Kolmogorov Entropy monotonically increases with the increasing coupling strength, which is a sufficient condition for chaotic behavior under ultrastrong coupling regime. The a...

Efficient neural communication between premotor and motor cortical areas is critical for manual motor control. Here, we used high-density electroencephalography to study cortical connectivity in patients with Parkinson's disease (PD) and age-matched healthy controls while they performed repetitive movements of the right index finger at maximal repetition rate. Multiple source beamformer analysi...

As a quantum theory of gravity, Matrix theory should provide a realization of the holographic principle, in the sense that a holographic theory should contain one binary degree of freedom per Planck area. We present evidence that Bekenstein’s entropy bound, which is related to area differences, is manifest in the plane wave matrix model. If holography is implemented in this way, we predict cros...

The area of signal processing is very wide. In this review paper we will focus on how the theory of nonnegative matrices may arise in the field of digital filter design: an area in which the role of nonnegative matrices is increasingly relevant due to the development of new technologies in the field of optical components and charge coupling devices. r 2005 Elsevier B.V.

large amounts of hydrocarbon reserves are trapped in naturally fractured reservoirs which arechallenging in terms of accurate recovery prediction because of their joint fabric complexity andlithological heterogeneity. canada, for example, has over 400 billion barrels of crude oil in fracturedcarbonates in alberta, most of this being bitumen of viscosity greater than 106 cp in the grosmontformat...

the increasing of software’s quality is a significant issue that attracts the attention of many researchers in this field. they are looking for a modeling that meets the users trust and reliance on software. therefore, the demand for high reliability software development has been increased as well. having suitable design, increasing reliability is required. coupling and cohesion are of among di...

proper decisions play a crucial role in any software architecture design process. an important decision of design stage is the selection of a suitable software architecture style. lack of investigation on the quantitative impact of architecture styles on software quality attributes is the main problem in using such styles. consequently, the use of architecture styles in designing is based on th...
