Authors: Zadbood Amineh , Noghondarian Kazem
Published: January 2012

Most of the studies in Response Surface Methodology commonly involve one response or quality characteristics, whereas in most industrial applications considering all responses simultaneously is required. Multiple Response Surface (MRS) Optimization Problems often deal with responses that are conflicting. In dealing with incommensurate responses, incorporating a decision maker’s preference information into the problem has lots of advantages although a few researches in MRS literature have taken this into attention. The purpose of this paper is to take a detailed look at the most prominent approaches that has been suggested so far in MRS, and also to review and discuss the classifications with a special focus on the decision maker’s preference information. In today’s competitive market satisfying the customer is of high importance. The DM can be a customer and reaching a compromise with an interactive method would help the firm to succeed in having loyal customers. A case study is applied to show that interactive method with existing MRS approach leads to better results.

Authors: Huang Jian Zhong , Chen Bai Fu , Ouyang Zhang Xi
Published: January 2012

The offshore outsourcing of IT services is more and more important in today’s IT industry. Applying a simple model with two countries, the “North” and the “South”, we analyze the optimal industrial competition policy which is set by a Competition Agency. During the interactions between the “North” and the “South”, a final IT product is provided by the northern oligopolistic firms, who utilize an input processed by the southern oligopolistic IT services providers with lower costs. In the paper, we focus on relations between IT services outsourcing and industrial competition policy. The Competition Agency plays an important role throughout the outsourcing process. The result shows that, by controlling the degree of competition, the IT services outsourcing rents can be appropriated perfectly.

Authors: Gao Ze Feng , Chen Jun , Liu Fei
Published: January 2012

The main theme of this paper is to present robust guaranteed cost control laws for a class of fuzzy bilinear systems (FBS) with parametric uncertainties. First, the piecewise Lyapunov function (PLF) method is utilized to design a fuzzy controller, which ensures the robust asymptotic stability of the closed-loop system, and then the robust guaranteed cost control law is also proposed. Second, based on the Schur complement and some variable transformations, some sufficient conditions are derived to guarantee the stability of the overall fuzzy control system via linear matrix inequalities (LMIs). Finally, a numerical example is utilized to demonstrate the validity and effectiveness of the proposed control scheme.
Distributed Generation and Network Upgrades Placements for Distribution System Expansion Planning
Authors: Su Chun Lien
Published: January 2012

In contrast with the traditional distribution expansion planning approach, significant giants can be realized in terms of outage loss, supply quality, and load carrying capacity from the distribution expansion with a suitable size and siting of distributed generation (DG). However, in order to achieve these planning goals, it often requires network upgrades to accommodate the anticipated power flows in the distribution system with DG. To improve utilization and expansion of distribution system, this paper proposes a methodology to derive the optimal strategy of generation expansion and network upgrades including line capacity upgrade, line switches, and network reconfiguration for multiobjective distribution expansion planning by minimizing network investment cost, feeder losses, customer interruption cost, and voltage drop. A multiobjective genetic algorithm (MOGA) is employed to quantify the effects of DG and network upgrades placements on distribution network under load increases and during distribution outages. To demonstrate the effectiveness of the proposed methodology, an IEEE feeder test system is selected for computer simulation to explore the benefits of DG placement for distribution system utilization and expansion.

Authors: Chen Ya Rong , Zhou Hong Ming , Guan Zai Lin , Shao Xin Yu
Published: January 2012

In the mixed-production context of make-to-stock (MTS) and make-to-order (MTO), the manufacturing system becomes more complex for comprehensive balance of multiple objectives, including resource utilization, work in process (WIP), on-time delivery and throughput. To deal with this complexity, a dynamic production plannning and control (PPC) model with the hybrid of workload control (WLC) and theory of constraint (TOC) is presented. While the proposed three-tiered hierarchy construction model is relatively similar to WLC model, but the way in which the workloads are controled has changed dramatically. The order acceptance deals with issues of order review and delivery setting in order to balance the overall resource capacity and requirements that is necessary for on-time delivery. The order release deals with issues of release mechanisms and rules in order to control the flow of work to the production floor that is necessary for WIP and resource utilization.And the scheduling deals with issues of bottleneck identicification and task sequencing in order to protect the bottleneck capacity that is necessary for throughput.
Simulation Study of Transmission Capacities for Overlaid Wireless Ad Hoc Networks
Authors: Liu Dan , Niu Shi Yuan , Li Di , Yin Chang Chuan
Published: January 2012

Transmission capacity has been defined in prior literature as an insightful metric for the transmission capability of the wireless networks. In general, it is hard to derive the analytical results for the transmission capacity without employing asymptotic analysis or bounding techniques. In this paper, we study the transmission capacity for overlaid wireless ad hoc networks by using computer simulation for the non-asymptotic case. We consider the scenario where a primary network (PR) and a secondary (SR) network coexist in the same geographic region and share the same spectrum, while the PR network has a higher priority to access the spectrum and the SR network limits its interference to the PR network by controlling its transmission intensity. We first present a simulation algorithm, then show that the simulation results conforms well to some known analytical results. We proved that with a small increment of the outage probability for the PR network, the sum transmission capacity of the overlaid network has a great gain over that of a single network. And with power control, the sum transmission capacity of the overlaid network will be improved compared to that without power control.

Comparison results show that the RGCNN model has higher correlation coefficient, less deviation, and saves about half training time, i.e., the RGCNN model has obvious advantages over the RBFNN model. Therefore, the novel RGCNN model for objective speech quality evaluation is feasible and effective.

Modified Joint Probability Data Association Algorithm Avoiding Track Coalescence
Authors: Chen Song Lin , Xu Yi Bing
Published: January 2012

Joint Probabilistic Data Association has proven to be effective in tracking multiple targets from measurements amidst clutter and missed detections. But the traditional Joint Probabilistic Data Association algorithm will cause track coalescence when the targets are parallel neighboring or small-angle crossing. To avoid track coalescence, a modified Joint Probabilistic Data Association algorithm is proposed in this paper. An exclusive measurement is defined for every target in the new algorithm. The exclusive measurement of a target is one measurement which associates with the target and has the maximum associated probability. The associated events of the exclusive measurement with other targets will be pruned, which resists two or more targets share the same measurement as a key measurement and avoids track coalescence. The simulation results show that the new algorithm can effectively solve track coalescence problem in all kinds of scenarios and keep a high tracking performance.

Software architecture has emerged as an important sub-discipline of software engineering; particularly in the realm of large system development. Collaboration software applications are inherently cooperative, requiring many software applications to coordinate their efforts to produce a software system application. Integral to this effort is developing shared understanding surrounding multiple artifacts, each artifact embodying its own model, over the entire development process. This focus on model collaboration embedded within a larger process is what distinguishes collaboration research in software engineering from broader collaboration research. This article first review a list of goals for software architecture, then collaboration software application, several possible future directions for collaboration in software engineering is presented. The article concludes by noting a problem in performing research on collaborative systems.
Study on Phase Comparison Pilot Protection for Six-Phase Transmission Lines Based on Six-Sequence Transformation
Authors: Wang Yan , Zhou Dan , Xu Song Xiao
Published: January 2012

Six-phase transmission system occupys a narrow line corridor, and it can also effectively improve power transmission density, so it gains more and more attention. A new scheme of phase comparison protection suitable for six-phase transmission lines was proposed in this paper. Because both ends of electrical quantities on six-phase transmission line are decoupled into six separate sequence components, of which opposite positive fault sequence component is independent with load current in typical six-phase transmission system, the scheme utilizes the sum of forementioned fault sequence components and same positive current sequence component and opposite negative current sequence component in proportion as the operating current in phase comparison pilot protection. The theoretical analysis and result of simulation confirm that the new scheme can correctly reflect any fault of the six-phase transmission lines, and it can overcome the disadvantages of the conventional protection under conditions of power swing, heavy load current and high transition resistances, and it can improve the sensitivity of phase comparison pilot protection and be used on six-phase transmission lines as main protection.
Determination of Pd(II) in Street Dust and Water Samples by FAAS after Preconcentration with Dimethylglyoxime-Anchored Organobentonite
Authors: Zhang Dong
Published: January 2012

A preconcentration method based on the adsorption of palladium-dimethylglyoxime -anchored organobentonite (DMG-bentonite) for the determination of palladium at trace levels by flame atomic absorption spectrometry (AAS) has been developed. The optimum experimental parameters for the adsorption and preconcentration of the palladium, such as pH value of medium, contact time, eluent and coexisting ion, have been investigated. The results showed that the palladium ion could be quantitatively retained by the DMG-bentonite in the pH range of 3–5 using citric acid/citrate buffer, the adsorption time was 20 min, and capability of adsorption was 8.73 mg•g-1. The palladium ion adsorbed on the DMG-bentonite could be completely eluated by using 1 mol•L-1 HCl. The detection limits of this method for palladium was 1.02µg•L-1 with an enrichment factor of 60. The method has been applied to the determination of trace amounts of palladium ion in street dust and environmental water with satisfactory results.

This paper presents the analysis, design and implementation of a novel open-winding permanent magnetic starter-generator using the open-winding permanent magnetic machine for overcoming the difficulties of voltage regulation, narrow speed range and low power factor of the permanent magnetic machine for the vehicles applications. In the proposed method, one side of the open-winding permanent magnetic machine is connected to rectifier for the DC voltage output, the other is connected to the inverter for the regulation of the DC voltage. And the open-winding machine can be reconstructed to be the conventional machine as the starter. In contrast to the conventional starter-generator for the vehicle, the speed range of the generation process and efficiency of the machine are improved obviously. A new control algorithm of double-loop for regulation of the DC voltage and current of machine is developed and verified by the simulation results.
