In order to meet the requirements of emerging demanding services, network resource management functionality that is decentralized, flexible and adaptive to traffic and network dynamics is of paramount importance. In this paper we describe the main mechanisms of DACoRM, a new intra-domain adaptive resource management approach for IP networks. Based on path(More)
— The structural topology optimization approach can be used to generate the structural design for some desired input-output (force-deflection) requirements. Optimization methods based on genetic algorithms (GA) have recently been demonstrated to have the potential for overcoming the problems associated with gradient-based methods. The success of the GA(More)
— Very often real-world applications involve multiple objectives. Research on multiobjective evolutionary optimization algorithms have amply demonstrated that they are capable of finding multiple and diverse non-dominated solutions which allows the user to choose among many solutions. Although it is difficult to evaluate the importance of the various(More)
This article proposes a multi-scale model suitable for describing patterns of store locations in a large-size supply-chain system. This model uses continuum approximation to simplify the detailed logistics network and supports various levels of decisions, such as robust logistics network designs and service area allocations for distribution centers.

OBJECTIVE To observe and analyze the application effect of ultrasound-guided modified Seldinger technique (MST) in Peripherally Inserted Central Catheter (PICC) catheterization. METHODS Two hundred patients treated with PICC catheterization from January 2013 to December 2015 were selected and randomly divided into two groups, namely, observation group and(More)
