During system restoration, it is critical to determine The start-up sequence of non-black-start generators according to post-blackout situations following a blackout. The generator start-up sequencing is a multi-objective optimization problem and the importance of different objectives varies a lot. In this paper, the corresponding optimization problem is formulated as a preference multi-objective optimization model based on preference optimization theory. The preference information of the proposed optimization model is expressed as a reference point in an a priori way. The r-NSGA-II algorithm, incorporating the reference solution-based dominance relation, is used to solve the preference multi-objective optimization model according to the specified reference point. The proposed generator start-up method can provide preferred optimal generator start-up sequences and corresponding restoration paths simultaneously. Simulation results of the New England 10-unit 39-bus power system and the western Shandong power system in north China demonstrate the basic features and the effectiveness of the proposed method.

Aiming at the large number of planning constraints faced by UAV's in low-altitude penetration, ambiguity and strong coupling among various factors, an intelligent UAV penetration algorithm based on moth fire suppression optimization algorithm is proposed. MFO algorithm is a novel swarm intelligence optimization algorithm. The main inspiration of this algorithm comes from the flying mode of the moth, which is called lateral positioning in nature. As a new bionic swarm intelligence optimization algorithm, the algorithm analyzes the biological principle of the moth fire suppression optimization algorithm, establishes a mathematical model for the algorithm implementation process, and simulates the algorithm through typical function optimization. The simulation experiment and comparative analysis show that the moth fire suppression optimization algorithm can reduce the overall voyage cost of the UAV's low-altitude penetration path planning, and the calculation speed is faster, besides, the stability and effectiveness can be guaranteed, which could effectively avoid the threat source and perform the low-altitude penetration of UAV.

Individual evaluation in small size groups is an important part for collaborative learning. To evaluate individual contributions, we use a comprehensive assessment method including self-evaluation and mutual-evaluation in freshmen seminar course in Southeast University of china. And the comparison and problem between self-evaluation and mutual-evaluation are presented and analyzed. Relations of the scores between leaders, members and their projects are discussed. Analysis shows that the proposed method could be an effective way to evaluate individual contributions to groups. However, the conclusion may depend strongly on the background that the course is for freshman in an engineering school.

On the basis of the related literature, we construct the theoretical hypotheses between core enterprise leadership style, inter-organizational trust and cooperation performance. We use the actual data of the process of the innovation cooperation in China, and do an empirical test with the help of SPSS17.0. The whole research shows that moderate transformational leadership behavior conducive to enhance the performance of cooperation; transactional leadership style and inter-organizational trust negatively related to increased cooperation performance; part of the mediating effect of inter-organizational trust exists between transformational leadership and cooperation performance.

This paper aims to study the logistics scheduling with due date assignment and batch delivery. A set of orders needs to be processed by the manufacturer and delivered to the customers upon completion. Each customer has a specific acceptable lead time. The manufacturer assigns a due date for one order by negotiating with the customers. The problem is to assign appropriate due date for the orders, and find a joint schedule of order processing at the manufacturer and order delivery from the manufacturer to the customers that minimize the total cost. The objective is to minimize the total tardiness penalty, due date assignment and delivery costs. For this problem, we analyze the complexity of the general case and study the solvability of multiple case by providing efficient algorithms.

A CPS is defined as integration of computation and physical processes. In cps, downsized and embedded devices execute physical processes by monitoring and controlling entities in the physical world. Service-oriented architecture (SOA) provides the concept of packaging available functionalities as interoperable services. Services can be used to construct applications. But, in the context of cyber-physical systems, there are special characteristics and requirements. For example, physical entities are exclusive, but services can be used by several consumers at the same time through multi-threading. Lots of applications are Safety-Critical in cyber-physical systems. Taking all these characteristics and requirements into consideration, this paper introduce application rebuild framework and lease protocol into cyber-physical systems. The atomicity property of lease protocol guarantees that an application either is granted the leases for all requested services or it gets no lease at all. Applications which aren't granted the leases for all requested services will be rebuilt by application rebuild framework to ensure applications will be started in time. The architecture of cyber-physical systems proposed by this paper can improve the availability and adaptability of application. A prototype system is implemented to show the practicability of the architecture of cyber-physical systems.

To help first year students adapt to their college lives and to enhance student learning, freshman seminar courses have been popular in many advanced countries. However, seminar courses in China are still in the beginning stage and are mainly for elective courses considering the large number of students in many majors. In this paper, implementation of a new required freshman seminar course, “Introduction to learning in the specialty of electronics and information” in Southeast University, is introduced. The course is composed of three education stages, i.e., lecture, investigation and project, during which the students can have closer and closer views to the applications of electronic science and engineering, and gain in-depth experience of relevant projects step by step. In addition, by making use of flexible class forms, various teaching methods, composite evaluation methods, and collaboration of a teacher team, the seminar course has been successfully run for about 170 students for the first time.

In order to further improve the operating performance of teleoperation robot system, and give full play to the advantages of augmented reality technology, this paper presents a human-computer interaction method with multi-dimensional information in the teleoperation augmented reality scenario. This method not only synthesizes the information the operator can directly perceive, but also the information that operators can not directly perceive is also conveyed to the operator by an intuitive way, and finally establishes the multi-dimensional information interaction channel between implement-side and host-side. Firstly the composition of the model's information content, the information acquisition way, and a way to convey information of the model are analyzed, and then several aspects of visual information interaction, the show mechanism of text prompts and voice prompts, hap tic interaction method, etc are analyzed in-depth separately. Experimental results show the teleoperation augmented reality system with multi-dimensional information could increase the operating accuracy and reduce the procedure time.

Owning to the gravitational force of earth, all the vehicles must rely on road surface to move so that in vehicle driving scene emulation it must guarantee vehicle to travel on the ground and the real time reaction of ground conditions, this is so called terrain matching problem. Terrain matching algorithm of driving simulation affects the fidelity of various vehicles, the three points or four points terrain matching algorithm has the disadvantage of terrain abridging in detail such as crater and mound which jeopardizes the fidelity of driving raining simulator. Adding two points of track into the four point's terrain matching which simplify the tracked vehicle as rigid system of six supporting points. Building the model of 6 points terrain matching algorithm will improve the fidelity of simulation.

By comparing the results derived from weighted average method and arithmetic average method, it prove that the former is superior to the latter.

To further understand the nitrogen removal mechanism in leachate treatment using aged-refuse-based bioreactor, 10 year aged refuse was used as adsorbent, ammonium chloride as adsorbate. The adsorption isotherms and thermodynamics, and adsorption mechanism were studied. The results show that: (1) The isothermal adsorption process of NH4+ on aged refuse can be fitted by Freundlich equations with a high correlation coefficient (0.9873 ~ 0.9907). (2) The adsorption process of NH4+ on aged refuse is spontaneous and exothermic. Temperature is conducive to the spontaneous adsorption but adsorption decreased. (3) In the absorption of ammonium by aged refuse, the main force is the hydrogen bonding and dipole bond for physical adsorption.
