    Multi-Echelon Reverse Supply Chain Network Design with Specified Returns Using Particle Swarm Optimization

    In this paper, the authors focus on the development of an optimization mathematical model for a reverse supply chain network that contains forward and reverse logistical plans in the multi-echelon system. In the reverse process, the defective products are re-turned to the original manufacture/supplier (specified returns) to be produced again....

    Efficient Localization Algorithm in Wireless Ad Hoc Sensor Networks by Utilizing Radical Centers

    This paper proposes an analytic localization algorithm by utilizing radical centers. Assume that a target node (blind node) can measure its distances to three or more anchor nodes (reference nodes). By picking three distance measurements to three anchor nodes, a radical center is computed. Through analytic formulation, the radical center...

    How Much Training is Enough for Secrecy Beamforming With Artificial Noise

    In this paper, the authors consider the joint design of training and data transmission signals for wiretap channels where the transmitter is to send a secrect massage to the receiver without being intercepted by the eavesdropper. The celebrated secrecy beamforming scheme, which may or may not be assisted by Artificial-Noise...

    Iterative Multicarrier Detector and LDPC Decoder for OFDM Systems

    In this paper, the authors propose iterative Soft-Input Soft-Output (SISO) multi-carrier detection (inter-carrier interference cancellation) and LDPC decoding of the OFDM system in the mobile channel. The proposed SISO multi-carrier detection and sum-product decoding of the LDPC-coded OFDM system can achieve better error rate performance than previous SISO multi-carrier detection...

    A Fault Detection System for an Autocorrelated Process Using SPC/EPC/ANN and SPC/EPC/SVM Schemes

    The Statistical Process Control (SPC) chart is effective in detecting process faults. One important assumption for using the traditional SPC charts requires that the plotted observations are independent to each other. However, the assumption of independent observations is not typically applicable in practice. When the observations are auto-correlated, the false...

    Intelligent Controller for Multiple-Input Multiple-Output Systems - Part I

    A Self-Organizing Fuzzy Controller (SOFC) has been developed for control engineering applications. However, in practical applications, it is difficult to choose the values of the SOFC's learning rate and weighting distribution appropriately to achieve reasonable control performance. In addition, the SOFC is mainly used to control single-input single-output systems. When...

    How Does Leadership Style Enhance The Effect Of Responsible Downsizing Strategy On Firm Post-Downsizing Performance?

    For coping with rapid changes in the business environment, firms use different strategies to create competitive advantages for survival or improve performance. Organizational downsizing is a strategy quite often used by firms, especially with the current world-wide economic recession. But after organizational downsizing, not only firm performance cannot be surly...
