The mechanism of blast damage to steel-clad concrete-filled steel tube (SCCFST) arched protective doors is studied using the dynamic response characteristics such loads under action shock wave loads, and ultimate load-bearing capacity formula derived based on “plastic hinge” mode limit analysis, which explores effect wave. design parameters each component door subjected waves discussed. Results...

Laser Shock Processing (LSP) is an innovative surface treatment technology. LSP can induce compress residual stress layer in the surface of metallic materials, which is used for improving the fatigue life. In this study, the propagation course of typical laser shock wave in material was analyzed according to the theory of plasticity dynamics and the theory of stress wave. The effects of laser s...

The Finite Element Method is a commonly used prediction method for dynamic simulations of plate bending problems. A major disadvantage of this method is its practical frequency limitation in that the computational loads become prohibitively large at higher frequencies. A newly developed Wave Based prediction technique aims to relax this frequency limitation through an enhanced computational eff...

Drowsiness is becoming a stern dispute in case of traffic accident. Along with physical activities such as eye blink, yawning, gripping of the human, people will mentally sleep with eyes open for few seconds. This will be accountable for severe accidents. The main objective of this research is 1) introducing a brain wave sensor which would be at ease in operational conditions to record EEG sign...

In this paper, we suggested new algorithms to discriminate between eight analogue modulated signals (amplitude modulation (AM), frequency modulation (FM), double side band (DSB), lower side band (LSB), upper side band (USB), vestigial side band (VSB), combined (AM-FM) and carrier wave (CW)). The simulation results show that the overall recognition of the new algorithms over 97% when the signal ...

Ac to DC converter is used for operating DC electrical machine and also supplies DC power to battery which is used for many purposes. The main purpose of this project is to compensate the harmonics by using harmonic current compensation and reactive power control. If reactive power is compensate prior to system then non linearity or harmonics present in the system does not much affect the exist...

We describe the effects of baseline ripple in an airborne submillimeter wave radiometer, which are caused by standing waves in the quasi-optical path. These baselines can be reduced with an improvement of the calibration loads and with a pathlength modulator. We have modelled the impact of the baseline on the retrieval of the volume mixing ratio profiles of the atmospheric constituents and we w...

Dispersion, impedance matching and resolution characteristics of an isotropic three-dimensional flat lens (“superlens”) are studied. The lens is based on cubic meshes of interconnected transmission lines and bulk loads. We study a practical realization of the lens, based on the microstrip technology. The dispersion equations that have been previously derived, are verified with full-wave simulat...

The success that banks have had deploying remote deposit capture has been tremendous over the past few years. The ability to decrease manual handling of checks and increases deposit breadth has certainly been a positive in what otherwise has not been the greatest of times in the banking community. However, as with any success along comes scrutiny. Echoes from the halls of Congress of not enough...
