Abstract The rapid development of hypersonic vehicles has motivated the related research dramatically while evasion becomes one challenging issues. Different from work based on premise that pursuers’ information is fully known, in this paper guidance for air-breathing (AHVs) against unknown pursuer dynamics studied. gradient descent employed parameter estimation pursuer. energy-optimized algori...

A new simple convergence acceleration method is proposed for a certain wide range class of convergent alternating series. The method has some common features with Smith’s and Ford’s modification of Levin’s and Weniger’s sequence transformations, but it leads to less computational and memory cost. The similarities and differences between all three methods are analyzed and some common theoretical...

1 SUMMARY In this project, we add a limited subset of staged functions to the Spatial hardware accelerator design language. This support includes implementation of language support for staged functions, analyses for optimizing performance and area, and generating synthesizable implementations of these staged functions. We evaluate these additions by comparing the runtime and area of a set of be...

Semi-active base isolation system has been proposed mainly to mitigate the base drift of isolated structures while in most cases, its application causes the maximum acceleration of superstructure to be increased. In this paper, designing optimal semi-active base isolation system composed of linear base isolation system with low damping and magneto-rheological (MR) damper has been studied for co...

In the real application of active control systems to mitigate the response of structures subjected to sever external excitations such as earthquake and wind induced vibrations, since the capacity of actuators is limited then the actuators saturate. Hence, in designing controllers for linear and nonlinear structures under sever earthquakes, the actuator saturation should be considered as a const...

We investigate a form of quintessential dark energy for which the time evolution of a scalar dilaton field φ is given by |φ(a)|/mP ≡ α1 ln t + α2t = α ln a + β a2ζ , where a is the scale factor of a spatially flat FRW universe. This ansatz for φ is motivated by generic solutions of a scalar dilaton field in some effective string theory models in four dimensions, which also captures basic featur...

according to iranian code of practice for seismic resistant design of buildings standard no. 2800, yazd is located in the place with the medium earthquake hazard [1]. due to the position of yazd with many historical and important buildings, maintaining these traditional heritages is an important task in civil engineering field. on account of these mentioned valuable buildings and region potenti...
