Crack detection is crucial for safety and cost-effective maintenance of concrete structures. Researchers have proposed several methods based on machine vision techniques to inspect the cracks on the bottom surface of concrete bridges, such as Fujita's method. However, it is difficult to obtain high-quality images and image processing results because of complex environmental and light conditions under...
Establishing efficient partnership in dynamic alliance is a fundamental process in the supply chain management (SCM). In the past, the state-of-the-art researches mainly focused on establishing effective factors selection model to evaluate candidate enterprises. While there are large numbers of candidate enterprises and a lot of concerned factors, it is a challenge for the SCM system in selecting...
A fuzzy multi-criteria model and an open storage network model about forest lookout station has been established in Baiyun District of Guangzhou City China. The correlative theory is fuzzy programming & stochastic programming. In order to have the optimum result for a priority, the genetic algorithm has been used.
A novel method for the design of log-domain filters is presented which is based on the operational simulation of orthonormal ladder networks. The approach permits the realization of a given arbitrary filter transfer functions. By using the method, a third-order log-domain elliptic lowpass filter with 1 dB ripples is designed. PSPICE simulations show the proposed filter possesses almost ideal frequency...
In remote sensing and military affairs, Infrared (IR) simulation of ocean scene has become more and more important nowadays. Stressing requirements for real-time IR scene generation include high performance and high precision. Although a lot of works present infrared simulations, those techniques cover only a few possible ways of water interacting with the environment. And how to calculate the temperature...
A resource search algorithm gravely affects the performance of P2P system. This paper proposes a probabilistic and exhaustive search algorithm, which has the merits of structured and unstructured P2P system. The topology of system employs a relaxed random multigraph which is scalable. The algorithm firstly evaluates the desired number of replica of data and query by the birthday paradox theory, which...
