The success of organizations operating in complex environments depends on how well its supply chain could adapt to disruptions caused by unanticipated events. Building this resilience requires the capability to identify risks and uncertainties and modeling the impact of them on operations. Both of these have proven to be very difficult to do effectively. With the emerging interest in promoting sustainability companies are now forced to not only consider factors that affect economic performance but also those relating to environmental and societal responsibilities. Thus, increasing resilience in sustainable supply chains (SSCs) calls for a more holistic approach to address risk;it is necessary to consider the risks originating within and outside the company and those affecting all supply chain partners;also, the risks due to and impacting all stakeholder groups must be incorporated. This paper presents a comprehensive review of risks in SSCs and a potential approach to model their impact. © 2010 IEEE.

Changing technology and increased constituent demand for government services derive the need for governmental responsiveness. The government organisations in the developing countries will be under increased pressure to change their bureaucratic systems to be able to respond rapidly to changing and increasing requirements and rapid technology advancements. This paper aims to present a conceptual framework for explaining the main barriers and drivers of public E-service development. Therefore, the framework provides a basic context within which the process and practice of E-Service can be implemented successfully in the public sector organisations. The framework is flexible enough to be adopted by governments at different levels;national or local by developing countries around the world.

WATER SCIENCE AND TECHNOLOGY 2009年第12期60卷 3051-3059页

作者： Zaqoot, Hossam Adel Ansari, Abdul Khalique Unar, Mukhtiar Ali Khan, Shaukat Hyat Department of Chemical Engineering Department of Computer Systems & Software Engineering Environment Quality Authority (Palestinian Authority)-PhD Scholar at the Institute of Environmental Engineering & Management Mehran university of Engineering and Technology and National Institute of Oceanography Oceanography Pakistan E-mail: hanreen2@***

Artificial Neural Networks (ANNs) are flexible tools which are being used increasingly to predict and forecast water resources variables. The human activities in areas surrounding enclosed and semi-enclosed seas such as the Mediterranean Sea always produce in the long term a strong environmental impact in the form of coastal and marine degradation. The presence of dissolved oxygen is essential for the survival of most organisms in the water bodies. This paper is concerned with the use of ANNs - Multilayer Perceptron (MLP) and Radial Basis Function neural networks for predicting the next fortnight's dissolved oxygen concentrations in the Mediterranean Sea water along Gaza. MLP and Radial Basis Function (RBF) neural networks are trained and developed with reference to five important oceanographic variables including water temperature, wind velocity, turbidity, pH and conductivity. These variables are considered as inputs of the network. The data sets used in this study consist of four years and collected from nine locations along Gaza coast. The network performance has been tested with different data sets and the results show satisfactory performance. Prediction results prove that neural network approach has good adaptability and extensive applicability for modelling the dissolved oxygen in the Mediterranean Sea along Gaza. We hope that the established model will help in assisting the local authorities in developing plans and policies to reduce the pollution along Gaza coastal waters to acceptable levels.

The difficulty of exploiting energy without damaging the environment is a highly discussed topic. The lack of energy (electricity) is actually an issue of nature preservation and it is also an obstacle. One solution to these problems is renewable energy, which affects the environment less. However, these energies are sometimes infeasible due to its high costs, by the potential energy generated that in most cases is not sufficient enough to enable them economically. However, there are some of them that have an acceptable power generation, as is in the case of hydrokinetic energy. There are many ways of taking advantage of this type of energy, some of them costly, some very complex and others still in development and/or unprecedented as is the case with 'Hidropólio'®, presented in this article. This article describes the equipment and its operating principle and also presents the results obtained in laboratory tests at the National Center of References of SHPs – CERPCH (Centro Nacional de Referências em Pequenas Centrais Hidrelétricas- CERPCH) at the Federal University of Itajubá – UNIFEI, whose results proved quite promising, mainly for use in sections of shallow river and low speeds.

In this paper, an improved version of online continuation method controller for PWM systems is presented. The online continuation method controller solves the PWM-type deadbeat control problem numerically. By using this algorithm, iterations for solving the set of nonlinear equations always start from a good solution candidate and therefore it can be used online. The original continuation method is modified so that it is applicable to real systems. The validity of the proposed control method is demonstrated by a laboratory-scale flexible arm manipulator.

In this paper we propose a new constellation that has better performance (in BER) with respect to custom QAM constellation. We compare the new one and two kinds of circular constellations with QAM. For comparison we chose them so that they have the same power average. Also we used FHT instead of FFT for all constellations and compared them with each other. Based on the results DMT, without cyclic prefix, with FHT has better performance with respect to FFT. Also the new constellation has a minor better performance in the channels which have maximum SNR=20 dB. Also it is very attractive that in the channel with SNR greater than 27 dB circular constellation (form II) has better performance with respect to form I especially when we use FHT.

This paper is concerned with the design of Multi-Inputs and Multi-Outputs (MIMO) predictive PID controllers, which have similar performance to that obtainable from model-based predictive controllers. A new PID control structure is defined which incorporates the prediction of future outputs and uses future set point. A method is proposed to calculate the optimal values of the PID gains from generalised predictive control results. A decentralized version of the predictive PID controllers is presented and the stability of the closed loop system is studied. Simulation studies demonstrate the superior performance of the proposed controller compared with a conventional PID controller. The results are also compared with generalised predictive control solutions.

In recent years, there has been considerable interest within the tracking community in the approach to data association based on the assignment algorithm. The focus of this paper is to describe a new dynamic S-D assignment algorithm. In the presence of clutter, missed detections, the new method incorporates the image intensity information into the dynamic assignment cost coefficient. To reasonably utilize the special feature of IR sensors, the association becomes more accurate and, at mean time, the complexity of the algorithm has not obviously increased. The simulation results show that the proposed approach has better performance than traditional approaches.

This paper explores the inclusion of dynamic reactive power devices such as synchronous condensers, static VAr compensators (SVC), static synchronous compensators (STATCOM), and other flexible AC transmission system (FACTS) controllers, in a restructured setting. The operators of such devices may need to offer reactive power at a cost to be adequately compensated. It is assumed in this paper that the marginal cost to a generator of producing reactive power is negligibly small and generators would therefore offer reactive power at zero cost. A reactive power offer from these other devices would be accepted if it reduces the overall production cost. The rationale for introducing this offer-based reactive power supply is discussed. Three cases of a small power system are used to illustrate how system constraints and supplier constraints give rise to additional operating costs such as minimum generation costs and lost-opportunity costs. In each case an appropriate reactive power offer, from a reactive power supplier that would otherwise have no economic incentive to participate, can be used to remove a binding constraint and lower the overall production cost. The goal of this approach is to provide a stronger economic incentive for investments of needed reactive power supply in appropriate locations.

In many mechanical systems, the tracking control is one of the most important issues. Therefore for the unstable system subject to actuator saturation, the domain of the initial states corresponding to an arbitrary reference signal, within which tracking condition can be achieved, is interesting to be considered. In this paper, an approximate tracking domain is derived analytically. First in Theorem 1, for simple case, it is constructed by using the partial Lyapunov function and the absolute stability theory. In the following Theorems 2 and 3, a new idea is used to obtain larger domains. Finally in the last section, a simple numerical example is given.
