This paper aims to investigate the integrated production/distribution and inventory planning for perishable products with fixed life time in the constant condition of storage throughout a two-echelon supply chain by integrating producers and distributors. This problem arises from real environment in which multi-plant with multi-function lines produce multi-perishable products with fixed life ti...

Analog frequency modulated (FM) systems offer advantages of reliable speech quality and simplicity, whereas code division multiple access (CDMA) systems promise high capacity, resistance to multipath fading, and simplified frequency planning. In this thesis, we investigate the performance of a wireless local loop (WLL) system that uses the frequency modulation with the CDMA technique. The perfo...

This paper presents an overview of the activities of CIGRE C6.19 Working Group (WG), focusing on the planning and optimization of active distribution systems. This builds on the recommendations of CIGRE WG C6.11 that focused on the development and operation of active distribution networks (ADNs). The C6.19 WG aims at addressing the following issues: (i) Survey on the state of the art on plannin...

in this paper, photovoltaic (pv) grid-connected inverter which is the core device in pv grid-connected system has been in depth research.an improved predictive current controller has been developed by the authors for single-phase grid-connected voltage source inverters (vsi).based on dsp tms320lf2407a, a 10 kw single-phase grid-connected inverter has been built in this paper.thus is aimed at us...

In this paper a sliding mode controller (SMC) is designed for a permanent magnet direct current (PMDC) motor to enhance the motor performance in the presence of unwanted uncertainties. Both the electrical and mechanical signals are used as the inputs to the SMC. The complete motor control system is simulated on a personal computer with different design parameters and desirable system performanc...

Database Service Provider (DSP) is a provider in the Internet that provides service in maintaining data so users can access their data anytime and anywhere from the Internet. DSP model introduces several challenges. An important issue is data confidentiality. In this paper we propose a Usage Control (UCON) model and architecture that can be enforced to support data confidentiality in DSP model....

D eveloping a single-processor platform is bad enough. Adding another to the mix could drive even the best developers over the edge, especially when the mix involves a general-purpose processor (GPP) and a DSP. Take heart. A new way of thinking and working allows DSP processes to make operating system calls that are processed by the GPP. Likewise, the operating system running on the GPP can con...
