Geometry of eccentrically braced frames (EBFs) in some cases causes the connection of link beam to the column. The details of such conditions should be studied carefully due to the full plastic rotation in the link beam. In this research, the behavior of link-to-column connection is modeled and the failure modes are considered. Based on the previous researches shear link can exhibit better beha...
در این پایان نامه پارامترهای مهم در مدارات دیجیتال توضیح داده شده و چند سلول جمع کننده متداول مورد بررسی قرار گرفته است. ایده های مختلفی که در پیاده سازی مدارات جمع کننده وجود داشته، شبیه سازی شده است. در پیاده سازی مدار سلول جمع کننده، در بعضی از مقالات طبقات ورودی و در بعضی دیگر طبقات خروجی متفاوت است. در مقالات متفاوت از منطق های cmos مکمل، نسبتی، ترانزیستور عبوری مکمل، گیت های انتقال، تابع ...
Interaction between trace element such as Copper, Molybdenum and Sulphor affecting not only on the rate of Absorption, but also on the metabolic activity. The studies has shown that excessive expense of full diet sulphor decreases notonly molybdenum's absorption, but also demineralization of tissue from above elements . Also interaction between molybdenum and copper decreases body availability ...
In this study a series of ambient vibration tests on the triple ferrocement elevated water tanks with 150 cubic meters volume, is carried out. In order to verify the dynamic characteristics of full, half-full and one full tanks (mass eccentric system), the different arrangements of sensors are used. The effects of base rotation are also considered in the tests. Natural frequencies and mode shap...
In this paper, we study the relation between the soft sets and soft Lie algebras with the lattice theory. We introduce the concepts of the lattice of soft sets, full soft sets and soft Lie algebras and next, we verify some properties of them. We prove that the lattice of the soft sets on a fixed parameter set is isomorphic to the power set of a ...
In recent years there has been an increased effort to investigate and improve the crashworthiness of passenger rail vehicles in the United States. The structural crashworthiness requirements for new rail vehicles are changing to include specifications for crash energy management and crush zones rather than primarily specifications of vehicle and component strengths. In addition, the structural ...
The most often used friction model for sheet metal forming simulations is the relative simple Coulomb friction model. This paper presents a more advanced friction model for large scale forming simulations based on the surface change on the micro-scale. The surface texture of a material changes if two surfaces are in contact under a normal load which is an effect of flattening due to normal load...
A new 3-D full-scale thermo-structural finite element model of two-stack FPGA with TSVs, which is developed from an experimentally validated single-stack FPGA model, is proposed. Typical 3-D distributions and evolutions of temperature and von Mises stress on both the active layers and TSVs are presented.
The most often used friction model for sheet metal forming simulations is the relative simple Coulomb friction model. This paper presents a more advanced friction model for large scale forming simulations based on the surface change on the micro-scale. The surface texture of a material changes when two surfaces are in contact under a normal load. This is caused by flattening due to combined nor...
Full Scale Accelerated Loading System, one part of “the Eleventh Five Year National Grand Technology Infrastructure Program” is a facility to evaluate the performance and service life of different kinds of pavements subjected to traffic loading under full controlled environment. While simulating the environments of frigid zone and permafrost zone, the accurate control of air temperature, road t...
