the pull- out strength of the reinforcement has a significant role on the function of the most reinforced soil structures. since the coarse grain soils have a better interaction with the reinforcement, they are mostly used in these structures. in most situations, we have to transfer these granular soils from the borrow area, usually far from the site of the project. this will impose a considera...

We consider a variant of the well-studied gossip-based model of communication for disseminating information in a network. Classically, in each time unit, every node u is allowed to contact a single random neighbor v. If u knows the data (rumor) to be disseminated, node v learns it (known as push) and if node v knows the rumor, u learns it (known as pull). While in the classic gossip model, each...

This paper proposes an Authorization-Pull support for Community Authorization Services (CAS), an authorization-push model for the Grid authorization by the Globus Alliance, to evaluate it in the role of a pull model. The proposed system tries to evaluate the advantages and use of an authorization-pull model in the grid scenario making use of CAS and compares the same with the push-model origina...

This study was conducted to investigate the push and pull factors in consumers’ decisions in choosing wedding banquet venues in Chongqing, China. The objectives of this research were to identify push and pull factors that motivated decision makers and to explore the relationships between the factors across decision makers’ demographic variables including “relationship with the new couple”, “per...

BACKGROUND/PURPOSE The purpose of this study was to review the authors' 25-year experience with redo pull-through procedures for Hirschsprung's disease including surgical technique and long-term outcome. METHODS From 1974 to now, over 325 patients with Hirschsprung's disease have been treated at C.S. Mott Children's Hospital. This includes 30 patients referred after an unsuccessful pull-throu...

In hard-switched converters, the switching frequency is limited by switching losses and EMI problems. However, high-switching frequency is necessary to reduce the converter size. Hence, soft switching is imperative at high switching frequency to obtain good efficiency. Push–pull converter is a preferred topology at medium power level. This paper proposes a novel resonant transition topology for...

OBJECTIVES Overhead athletic activities and scapula dyskinesia are linked with shoulder pathology; pull-ups are a common training method for some overhead sports. Different pull-up techniques exist: anecdotally some are easier to perform, and others linked to greater incidences of pathology. This study aims to quantify scapular kinematics and external forces for three pull-up techniques, thus d...

The static pull-in instability of beam-type microelectromechanical systems (MEMS) is theoretically investigated. Two engineering cases including cantilever and double cantilever microbeam are considered. Considering the midplane stretching as the source of the nonlinearity in the beam behavior, a nonlinear size-dependent Euler-Bernoulli beam model is used based on a modified couple stress theor...

INTRODUCTION The requirements of minimally invasive surgery (MIS) show a significant similarity to the conditions of teleoperation tasks in nuclear plants and other inaccessible working areas. The software package KISMET (Kinematic Simulation, Monitoring and Off-Line Programming Environment for Telerobotics) is under development at Kernforschungszentrum Karlsruhe (KfK), Germany, since 1986, for...

We study the influence of von Karman nonlinearity, van der Waals force, and a athermal stresses on pull-in instability and small vibrations of electrostatically actuated mi-croplates. We use the Galerkin method to develop a tractable reduced-order model for elec-trostatically actuated clamped rectangular microplates in the presence of van der Waals forcesand thermal stresses. More specifically,...
