Optimal Scheduling of PEV Charging/Discharging in Microgrids with Combined Objectives  [PDF]
Chong Cao, Ming Cheng, Bo Chen
Smart Grid and Renewable Energy (SGRE) , 2016, DOI: 10.4236/sgre.2016.74008
Abstract: While renewable power generation and vehicle electrification are promising solutions to reduce greenhouse gas emissions, it faces great challenges to effectively integrate them in a power grid. The weather-dependent power generation of renewable energy sources, such as Photovoltaic (PV) arrays, could introduce significant intermittency to a power grid. Meanwhile, uncontrolled PEV charging may cause load surge in a power grid. This paper studies the optimization of PEV charging/discharging scheduling to reduce customer cost and improve grid performance. Optimization algorithms are developed for three cases: 1) minimize cost, 2) minimize power deviation from a pre-defined power profile, and 3) combine objective functions in 1) and 2). A Microgrid with PV arrays, bi-directional PEV charging stations, and a commercial building is used in this study. The bi-directional power from/to PEVs provides the opportunity of using PEVs to reduce the intermittency of PV power generation and the peak load of the Microgrid. Simulation has been performed for all three cases and the simulation results show that the presented optimization algorithms can meet defined objectives.

Option contracts in fresh produce supply chain with circulation loss
Chong Wang,Xu Chen
Journal of Industrial Engineering and Management , 2013, DOI: 10.3926/jiem.667
Abstract: Purpose: The purpose of this paper is to investigate management decisions via option contracts in a two-stage supply chain in which a fresh produce supplier sells to a retailer, considering the circulation loss of the fresh produce. Design/methodology/approach: Authors propose a Stackelberg model to analyze the supply chain members’ decisions in the decentralized supply chain compared with the integrated one under the newsvendor framework. Findings: The results illustrate that there exists a unique optimal option order quantity for the retailer and a unique optimal option order price for the supplier giving certain conditions; furthermore, option contracts cannot coordinate the fresh produce supply chain when the retailer only orders options. Originality/value: Agricultural products especially fresh produce’s characteristics such as circulation loss and high risk are considered. Option contracts and game theory are combined to manage the fresh produce supply chain’s risk. The proposed tool and models are hoped to shed light to the future works in the field of supply chain risk management.

The Thermodynamic Transitions of Antiferromagnetic Ising Model on the Fractional Multi-branched Husimi Recursive Lattice
Ran Huang,Chong Chen
Physics , 2014, DOI: 10.1088/0253-6102/62/5/19
Abstract: The multi-branched Husimi recursive lattice has been extended to a virtual structure with fractional numbers of branches joined on one site. Although the lattice is undrawable in real space, the concept is consistent with regular Husimi lattice. The Ising spins of antiferromagnetic interaction on such a sets of lattices were calculated to check the critical temperatures ($T_{c}$) and ideal glass transition temperatures ($T_{k}$) variation with fractional branch numbers. Besides the similar results of two solutions representing the stable state (crystal) and metastable state (supercooled liquid) and indicating the phase transition temperatures, the phase transitions show a well-defined shift with branch number variation. Therefore the fractional branch number as a parameter can be used as an adjusting tool in constructing a recursive lattice model to describe real systems.
An Approach to Generation of Process-Oriented Requirements Specification  [PDF]
Jingbai Tian, Keqing He, Chong Wang, Huafeng Chen
Journal of Software Engineering and Applications (JSEA) , 2009, DOI: 10.4236/jsea.2009.21002
Abstract: In service-oriented computing, process model may serve as a link to connect users’ requirements with Web Services. In this paper, we propose an approach and related key techniques to generate process-oriented requirements specification from user’s goal. For this purpose, a requirements description language named SORL will be provided to capture users’ requirements. Then, a unified requirements meta-modeling frame RPGS will be used to construct reusable domain assets, which is the basis of generating requirements specifications. Finally, a set of rules are defined to extract process control structures from users’ requirements described with SORL, so that we can convert requirements description into process-oriented requirements specification smoothly.
A Solution for Cross-docking Operations Planning, Scheduling and Coordination  [PDF]
Zhengping Li, Wei He, Cheng Hwee Sim, Chong Chuan Chen
Journal of Service Science and Management (JSSM) , 2012, DOI: 10.4236/jssm.2012.52014
Abstract: Crossdocking is defined as an operational strategy that moves items through consolidation centers or cross docks without putting them into storage. As the need to move inventory faster increases, more logistics managers are turning to crossdocking but the ability to execute such strategy well depends on good planning, dynamic scheduling and coordina-tion. This paper introduces our research and development work on cross docking solution in three aspects: optimized planning on container grouping, clustering, sequencing and allocating containers to docks; real-time scheduling handles the dynamics of container arrivals and actual pallet transfers; and cross-docking coordination conducts real-time task assignment/sequencing and resource management to deal with dynamic changes.

International Journal of Medical Physics,Clinical Engineering and Radiation Oncology (IJMPCERO) , 2013, DOI: 10.4236/ijmpcero.2013.24021
Abstract:

Purpose: To evaluate planning quality and dosimetric differences of clinically deliverable 3D conformal plans generated from Tomotherapy with TomoDirectTM (TD) and conventional field-in-field approach in prone breast treatment. Materials and methods: Total of twelve randomly selected early stage left breast patients who went through lumpectomy and were previously treated on traditional Linear Accelerator (LINAC) have been re-planned and tested on Tomotherapy TomoDirect module. Baseline prescription dose was chosen at 50.4 Gy (1.8 Gy × 28 fractions) to cover ≥95% of PTV for planning criteria with other critical structure dose constraints in the thoracic region. Planning outcomes such as D95 (95% of volume of PTV receiving the prescribed dose), D5 and D1, heart, both lungs as well as the contralateral breast were simultaneously evaluated. Conformity of the prescription isodose/volume to PTV was evaluated as conformity index (CI) and dose uniformity was also evaluated with homogeneity index (HI) in the same study series. All outcome parameters were analyzed and summarized to evaluate dosimetric impact of planning qualities between these two planning platforms. Results: The planning results indicate that CI, HI, D95, D5 and D1 of PTV, critical structures such as heart, ipsilateral and contralateral lungs as well as contralateral breast doses were comparable but with better overall statistical end points from TD plans. The D95, D5

Abstract: hrough interpreting Hui E's twelve prefaces in the existing Baishi Wenji collected by Kanazawa-Bunko Museum ,we can determine the actual process of the spread of the 70 volumes of Baishi Wenji to Japan . The research on Hui E's life helps to discover the close relationship between Baishi Wenji and the historical background of Zen's initial spread to Japan . Baishi Wenji is not only a canonical collection of essays in Japan , but an important Buddhist classics guiding the public to the Pure Land . Bai Juyi himself was worshipped as Manjusri buddisattva and was enshrined in the Putuo-Luojia Mountain by Hui E instead of the Mercy Buddha Temple . Bai had a great influence on the scholars'B uddhist belief in Japan's Heian and Kamakura ages .It is also one of the core reasons that Baishi Wenji becomes a cornerstone of Japanese classical culture .
The spiral spin state in a zigzag spin chain system
Meihua Chen,Chong Der Hu
Physics , 2010, DOI: 10.1103/PhysRevB.84.094433
Abstract: We considered a spin chain with nearest neighbor and next nearest neighbor exchange interactions, anisotropic exchange interaction and Dzyaloshinskii-Moriya interaction. The conditions of the spiral spin state as the ground state were analyzed. Our method was to build the connection between the spiral state and the fully polarized state with a unitary transformation. Under this transformation, anisotropic exchange interaction and Dzyaloshinskii-Moriya interaction can be transformed to each other. Then we used positive semi-definite matrix theorem to identify the region of fully polarized state as the ground state for the transformed Hamiltonian, and it is the region of spiral spin state as the ground state of the original Hamiltonian. We also found that the effect of Dzyaloshinskii-Moriya interaction is important. Its strength is related to the pitch angle of spiral spins. Our method can be applied to coupled spin chains and two dimensional triangular lattice systems. The result can be compared with experiment data.
