Two-dimensional weakly-singular Symmetric Galerkin Boundary Elements (SGBEMs) are developed, following the work of [Han and Atluri (2003)], using non-hypersingular integral equations for tractions. Specifically, the present 2D SGBEM is used to compute the stress intensity factors for arbitrary-shaped line cracks, including embedded, edge, branching, and intersecting cracks. The computed stress ...

Based on the panel data for 2005-2011, the paper conducts an empirical analysis on the efficiency and its determinants of China's service outsourcing industry by using the three-stage DEA technique. The empirical results show that the production efficiency of the service outsourcing industry in the year of 2011 is 0.803 from Super-DEA model and 0.573 from standard DEA model. The too-small scale...

In order to ensure superiority of fuel and improve start and stop performance of hybrid electric vehicle, battery is used in the system. Limited by vehicle’s size, traditional hybrid electric vehicles can only carry a limited number of batteries, resulting in a relatively short running distance in one battery charge cycle. To improve energy using efficiency and increase vehicle safety, composit...

Due to high efficiency and good scalability, hierarchical hybrid P2P architecture has drawn more and more attentions in P2P video streaming applications recently. The problem about Super Group Peers (SGPs) selection, which is the key problem in hierarchical hybrid P2P architecture, is becoming highly challenging because super peers must be selected from a huge and dynamically changing network. ...

In this study, we adopt a three-stage approach, DEA method, Frontier regressions, and DEA method to estimate bank efficiency based on information obtained from 29 banks in Taiwan for the period from 2002 to 2004. In the first stage, we employ super SBM (super Slacks-Based Measure) to estimate the scores relating bank efficiency including internal risk. In the second stage, a stochastic frontier...

A super-peer is a node in a peer-to-peer network that operates both as a server to a set of clients, and as an equal in a network of super-peers. Super-peer networks strike a balance between the inherent efficiency of centralized search, and the autonomy, load balancing and robustness to attacks provided by distributed search. Furthermore, they take advantage of the heterogeneity of capabilitie...

this research was carried out to evaluate the effect of super-absorbent and manure on growth, yield, physiological and biochemical characteristics of geranium under deficit irrigation at research greenhouse of faculty of agriculture, lorestan university, iran, in 2014. the experiment was arranged factorially based on a completely randomized design with six replications. factor a was substrate c...

Interactive image segmentation is a process that extracts a foreground object from an image based on limited user input. In this paper, we propose a novel interactive image segmentation algorithm named Perfect Snapping which is inspired by the presented method named Lazy Snapping technique. In the algorithm, the mean shift algorithm with a boundary confidence prior is introduced to efficiently ...

This paper aims to make the super-resolution of a high-resolution image from a sequence of low-resolution frames containing non-stationary objects. The challenges of making super-resolution image, like unavoidable smoothing effects, introduction of artifacts, computational efficiency in time and computational efficiency in memory requirements, are considered and a novel method is proposed to so...
