The plurality effect of topographical irregularities on site seismic response

引用

Earthquake Engineering and Engineering Vibration 2019年第3期18卷 521-534页

作者： Saeed Ghaffarpour jahromi Sama Karkhaneh Department of Civil Engineering Shahid Rajaee Teacher Training University

Topography can have signifi cant eff ects on seismic ground response during an earthquake because topographic irregularities cause considerable diff erences between the seismic waves emitted by the source and the waves reaching the ground surface. When a seismic motion happens in a topographically irregular area, seismic waves are trapped and refl ected between the topographic features. Therefore, the interaction between topographies can amplify seismic ground response. In order to reveal how interaction between topographies infl uences seismic response, several numerical fi nite element studies have been performed by using the ABAQUS program. The results show that topographic features a greater distance between the seismic source and the site would cause greater seismic motion amplifi cation and is perceptible for the hills far away from the source and the ridges. Also, site acceleration response is impacted by surrounding topography further than site velocity and displacement response.

A Stable Analytical Solution Method for Car-Like Robot Trajectory Tracking and Optimization

引用

IEEE/CAA Journal of Automatica Sinica 2020年第1期7卷 39-47页

作者： Keyvan Majd Mohammad Razeghi-jahromi Abdollah Homaifar School of Computing Informaticsand Decision Systems EngineeringArizona State UniversityTempeAZ 85281 USA ABB Corporate Research Center RaleighNC 27606 USA Department of Electrical and Computer Engineering North Carolina A&T State UniversityGreensboroNC 27403 USA

In this paper, the car-like robot kinematic model trajectory tracking and control problem is revisited by exploring an optimal analytical solution which guarantees the global exponential stability of the tracking error. The problem is formulated in the form of tracking error optimization in which the quadratic errors of the position, velocity, and acceleration are minimized subject to the rear-wheel car-like robot kinematic model. The input-output linearization technique is employed to transform the nonlinear problem into a linear formulation. By using the variational approach, the analytical solution is obtained, which is guaranteed to be globally exponentially stable and is also appropriate for real-time applications. The simulation results demonstrate the validity of the proposed mechanism in generating an optimal trajectory and control inputs by evaluating the proposed method in an eight-shape tracking scenario.

Hydrophobic silica nanoparticle-stabilized invert emulsion as drilling fluid for deep drilling

引用

Petroleum Science 2017年第1期14卷 105-115页

作者： maliheh Dargahi-Zaboli Eghbal Sahraei Behzad Pourabbas Department of Chemical Engineering Petroleum Research CenterSahand University of TechnologyTabrizIran Department of Polymer Engineering Nanostructured Materials Research CenterSahand University of TechnologyTabrizIran

An oil-based drilling fluid should be stable and tolerant to high temperatures for use in deep drilling. An invert emulsion of water in oil is a good choice as an oil- based drilling fluid which is a mixture of a solid phase and two immiscible liquid phases stabilized by a polymeric surfactant. In deep drilling, due to high temperatures, the polymeric surfactant degrades and a phase separation occurs. Here, octadecyltrimethoxysilane-modified silica nanoparticles were used to form a stable invert emulsion of water in oil for the drilling fluid model which resulted in a milky fluid with the formation of 60 gm water droplets. In addition, rheological study showed that using hydrophobic silica nanoparticles resulted in a stable water in oil invert emulsion with desired properties for a drilling fluid that can be modified by adjusting the nanoparticle nature and content. Aging experiments at 120 ℃ indicated that they also have good stability at high temperatures for challenging drilling operations.

Influence of ECAP on the fatigue behavior of age-hardenable 2xxx aluminum alloy

引用

International Journal of Minerals,Metallurgy and Materials 2015年第3期22卷 285-291页

作者： M.Namdar S.A.Jenabali jahromi Department of Materials Science and Engineering School of Engineering Shiraz University

The fatigue behavior under load control and the mechanical properties of commercial 2011 aluminum as an age-hardenable A1 al- loy was studied. To estimate the effects of the equal channel angular pressing （ECAP） process, solution heat treatments, and aging on the fa- tigue life, tests were conducted at four different stages： furnace cooling; furnace cooling plus one ECAP pass; solid solution heat treatment, quenching, one ECAP pass plus aging at peak age level; and the T6 condition. Only one pass was possible at room temperature because of the high strength of the material. The fracture surface morphology and microstructure after fatigue were evaluated by scanning electron mi- croscopy （SEM）. The experimental results revealed that the optimum fatigue life under load control, the tensile strength, and the Vickers hardness of the material were interdependent. The optimum fatigue life under load control was achieved by increasing the tensile strength and hardness of the material.

Non-alcoholic fatty liver disease and thyroid dysfunction:A systematic review

World Journal of Gastroenterology 2014年第25期20卷 8102-8109页

Thyroid hormones are totally involved in the regulation of body weight, lipid metabolism, and insulin resistance. Therefore it is anticipated that thyroid hormones may have a role in the pathogenesis of non alcoholic fatty liver disease(NAFLD) and non alcoholic steatohepatitis(NASH). In this study, we reviewed the current literature on the association between thyroid dysfunction and NAFLD/NASH. A search for English language medical literature reporting an association between thyroid dysfunction and NAFLD/NASH in humans was conducted across PubMed, ISI Web of Science, and Scopus in August, 2013. Out of 140 studies initially identified through the search, 11 relevant articles were included in the final review. Thyroid dysfunctions in the form of overt or subclinical hypothyroidism are prevalent among patients with NAFLD/NASH. Hypothyroidism appears to be an independent risk factor for NAFLD/NASH in some studies; however, other newly published studies failed to find such anassociation. The results of the studies on the role of thyroid abnormalities in NAFLD/NASH are inconsistent, and further research is recommended to determine the relationship between hypothyroidism and NAFLD/NASH and the underlying mechanisms.
