The El Golfo earthquake of August 7, 1966 (mb = 6.3, Ms = 6.3) occurred near the mouth of the Colorado River at the northern end of the Gulf of California. Synthetic seismograms for this event were computed for both the body waves and the surface waves to determine the source parameters of the earthquake. The body-wave model indicated the source was a right lateral, strike-slip source with a de...

Abstract—Finding the linear and nonlinear responses of a typical single-degree-of-freedom system (SDOF) is always being regarded as a time-consuming process. This study attempts to provide modifications in the renowned Newmark method in order to make it more time efficient than it used to be and make it more accurate by modifying the system in its own non-linear state. The efficacy of the prese...

—Distribution of the plains pocket mouse (Perognathus flavescens) overlaps tallgrass prairies in northeastern parts of the species’ range in the central United States. Distribution and abundance of the plains pocket mouse appears negatively impacted by agricultural practices during the last century due to the scarcity of records throughout the region. In eastern Nebraska, few plains pocket mice...

D-002, a mixture of six higher aliphatic alcohols purified from beeswax, has been shown to produce anti-inflammatory effects in experimental models, devoid of gastrotoxic or hepatotoxic effects. Some studies have demonstrated that D-002 exerts analgesic effects, but just related to its anti-inflammatory action. The objective of this study was to compare the effects of D-002, naproxen, aspirin a...

In this paper, the combination of RBF (Radial Basis Function) neural network and sliding mode control, which is used for vibration control, is examined. The approach is based on a sliding mode control methodology which drives the system towards a sliding surface by tuning the parameters of the controller using Gaussian radial basis function neural network. The input and output of RBF neural net...

With the continuous development of traffic construction, road engineering inevitably crosses aeolian sand river valley area. Compared with general sandy soil and silty soil, cohesionless foundation has similar properties fluid higher liquefaction potential. Precast cement pile can greatly improve vertical bearing capacity foundation, but this paper finds that it also antiliquefaction effect whe...

In the given work the problem of construction (synthesis) of mathematical model of unknown or littleknown external load (EL) on open dynamic system is considered. Such synthesis is carried out by special processing of the experimentally measured response of dynamic system (method of identification). This problem is considered in two statements: the synthesis of EL for single model and the synth...
