the main objective of this article is evaluation of the simplified models which have been developed for analysis and design of liquid storage tanks. the empirical formulas of these models for predicting maximum sloshing wave height (mswh) are obtained from mass spring models (msm). a finite element modeling (fem) tool is used for investigating the behavior the some selected liquid storage tanks...

Proposed is a new subband adaptive filter (SAF) algorithm by minimizing Huber’s cost function that is robust to impulsive noises. Generally, this algorithm works in the mode of the normalized SAF (NSAF) algorithm, while it behaves like the sign SAF (SSAF) algorithm only when the impulsive noises appear. To further improve the robustness of this algorithm against impulsive noises, the subband cu...

Femtosecond time-resolved pump-probe experiments were carried out to study ultrafast lattice dynamics of ferroelectric lithium tantalate. Both the fully symmetric (A1 mode) and doubly degenerate (E mode) coherent phonons at the center of the Brillouin zone were excited via impulsive stimulated Raman scattering, as confirmed by the excitation intensity dependence.

Steam cooking using parabolic trough collectors is a well-established sustainable technology. The augmentation of thermal energy storage (TES) system with such will make the technology completely reliable on renewable source. However, there are limited research findings to improve performance TES heat exchangers by adopting non-structural and non-elemental modifications. In this article, experi...

Teenagers are often impulsive. In some cases this is a phase of normal development; in other cases impulsivity contributes to criminal behavior. Using functional magnetic resonance imaging, we examined resting-state functional connectivity among brain systems and behavioral measures of impulsivity in 107 juveniles incarcerated in a high-security facility. In less-impulsive juveniles and normal ...

Optical control of elementary molecular motion through impulsive stimulated Raman scattering is enhanced by means of timed sequences of femtosecond pulses that are produced by pulse-shaping techniques. In particular, terahertz-rate trains of femtosecond pulses are used for repetitive impulsive excitation of individual phonon modes in an a-perylene molecular crystal. When the pulse repetition ra...

We study a control system which includes several impulse modulators employing some kind of frequency modulation. It is shown how to chose periodic external actions in order to ensure the existence of a synchronous periodic mode, i.e. of such a mode that all the modulators emit impulses with the same frequency. 1 Problem Setting We consider an asynchronous impulsive system with m impulse modulat...

this study examined the effects of cooperative learning techniques (clt) on vocabulary achievement of reflective/impulsive iranian efl learners. from among 130 students at fajr institute in dehdasht, kohkiloyeh and boyer ahmad province, iran, 90 participants were selected based on their performance on the oxford placement test (opt). the participants were then divided into two experimental grou...

a finite element analysis is presented for sloshing and impulsive motion of liquid-filled conical tanks during lateral anti-symmetric excitation. the performed analyses led to the development of a number of charts which can be used to identify the natural frequency, the mode shapes of conical tanks for both fundamental and the cos(θ)-modes of vibration. conical tank geometry was described with ...
