Title: Big Data Issues and Challenges
Abstract:  Nowadays, the immense use of computers in daily life leads to the creation of big data. Big data is a collection of vast data stored together and its term is used to describe the exponential growth of structured and unstructured data. Big data has three characteristics: volume, velocity, and variety. Such data can be found in many places, such as personal computers, universities archives, news archives, and textual documents. The most tremendous growth of these data can be found in social media. Social media technologies provide many different forms of presenting information, such as in magazines, Internet forums, weblogs, social blogs, micro-blogging, wikis, social networks, podcasts, photographs or pictures, videos, rating, and social bookmarking. Several attempts have been conducted to deal with massive data in social media, such as news extraction, aggregation, clustering, news topic detection and tracking, and social network analysis. Additional technologies, such as massive parallel-processing databases, distributed file systems, and cloud computing technologies, have been introduced to manage big data. However, these methods face the challenges of extracting, transformation, integrating, sorting, and manipulating data. The visualization of social media data is not feasible. However, realizing and understanding the events that occur in society is important to users. Therefore, in this talk will summarize the issues and challenges of big data.

Title: Key techniques of 5G and its beyonds in sea-adaptive communications and networking
Abstract: In the report, some traditional ways for marine communication is narrated briefly such as VHF and WiMAX for line-of-sight communication, and shortwave reflection communication, scattering communication, satellite and microwave relaying for beyond-line-of-sight communications. Then some communications techniques in 5G and beyond are analyzed. 
What kind of communication can be called sea-adaptive? That is a good question and some potential answers may be put forward by us in this conference hall today. There are so many interesting topics in the field of maritime communication and underwater acoustic communication, searching and detection, e.g. a new method to provide additional degree of freedom to enhance the capacity. 
We have to admit these topics are much more complex and also much more difficulty for each one of us, even for excellent scholars and researchers around the world. Fortunately, they are not much ahead from us, and in certain areas we are running on the same line with them. Finally, let’s wish the meeting success and may more and more achievements are taken by us all!

Title:  Planning of Charging Facilities of Electric Vehicles with Applications 
Abstract: Appropriate planning of charging facilities is of significant importance for the development of electric vehicles (EVs). Given this background, a planning model for siting and sizing of EV charging facilities based on zonal charging demand index is proposed with spatial and temporal characteristics of charging demands considered. A charging load prediction model based on the analysis of charging behaviors is first presented. The demands of different charging facilities are subsequently calculated with the inputs of daily energy charging demands and the maximum plug-in number of EVs. Then, the planning region is divided into several disjointed geographical zones, and the charging demand index in each zone determined. Those zones with higher charging demand indices are selected as the candidates for allocating charging facilities. Finally, the planning scenario of EV charging facilities in 2020 in Hangzhou City of China is employed to illustrate the essential features of the developed model.

Title: Smart Power Distribution and Energy Efficiency Management System
Abstract: According to authoritative statistics, in 2017, direct electrical fires in China accounted for more than 34% of all fires, and 70% of electrical fires were caused by switches, the first in the world. The main reason was that ordinary distribution switches did not play a protective role. There are more than 80% of energy efficiency in the construction field, and 100% of power distribution equipment will use cloud scheduling in important situations. Power distribution has entered a new era of the Internet of Things. The cloud-based smart security distribution box and cloud-based energy efficiency management platform is an innovative set of electrical fire warning and prevention equipment and energy-saving management platform for the current frequent occurrence of electrical fire accidents in China. The system is a cloud-based service platform that uses wireless communications to enable human-app app interactions. Data encryption technology ensures safe operation. It can be used without restrictions of time, place, and environment, and can be accessed through the Internet (computer, mobile phone APP, touch screen). The authorized account number and password can remotely monitor the operation of the user's power system in real-time, and truly achieve the goal of preventing fires and improving the fire prevention and control capabilities. The index management can effectively monitor the fluctuation of energy consumption of each system and equipment. With the analysis of the energy efficiency curve offset, the system can continue to carry out energy-saving work, formulate targeted energy-saving strategies for different equipment, and continuously optimize and improve to achieve the best energy saving effect. Although the process of energy saving is complex and professional, all analysis and processing can be done by the cloud system. The cloud service platform makes the energy system management simple and clear, allowing decision makers to easily manipulate and make informed decisions.

Title: Fast Calculation Method of UCAV Maneuver Flight Control Based on RBF Network
Abstract: In order to solve the mathematical characterization and real-time generation of UCAV tactical maneuvers, a solution based on RBF network was proposed. Firstly, the characteristics and characterization methods of tactical maneuver trajectory are studied. An optimal control model of maneuvering trajectory is established and solved by genetic algorithm to generate sufficient neural network training samples. Secondly, based on the fitness function value and initial conditions as the input, and the key point control quantity of tactical maneuvers as the output, an air combat tactical maneuver trajectory rapid generation system based on RBF network was built. Finally, the RBF network is trained using the Recursive Least Squares (RLS) method. The training error was in the order of 10^-5, which indicated that this method could realize the nonlinear mapping relationship between the fitness value and the trajectory with high accuracy. And through this network could quickly generate high-stability, UCAV executable maneuver trajectory.

Abstract: This article proposes an improved iterative frequency domain decision feedback equalization(IBDFE) for the unique word(UW) based system of space-time block coded-single carrier frequency domain equalization(STBC-SC-FDE). Compared with the conventional IBDFE, this algorithm uses minimum mean square error(MMSE) equalization and a noise prediction module based on UW instead of the feedback equalization part, while maintain the feedforward equalization. It is shown from the simulation results that the improved IBDFE can achieve satisfactory performance without iterations.

Title: Fault Location Method of Distribution Network Based on FTU Information Comparison and Search
Abstract: This paper analyses the characteristics of common methods of fault location using feeder terminal unit (FTU) in AC distribution network. When missing report and false alarm of FTU happen, the matrix method will be wrong, although the intelligent optimization algorithm has a certain fault tolerance rate, but it is easy to fall into local convergence and achieve more complexity. Aiming at the above problems, this paper presents a comparative information search method, obtained by using the distribution network topology of the FTU reservation information compared with the actual reporting information, fault calculation similarity of each area, so as to search the most similar regional information reporting information and reservation, which can effectively reduce the fault location time and improve the accuracy of fault location finally, the normal operation of the distribution network will come. It simulates the single fault of each region in a 5 power distribution system, and the introduction of conditional probability to achieve the missing report and false alarm of FTU, after checking a lot and systematically, it proves that the method is simple and effective, and has a high fault tolerance rate.

Title: Research on TBCC-RR Reusable Vehicle Launch System Based on Electromagnetic Propulsion 
Abstract:
The traditional non-reusable launch vehicle is the main approach to complete space launch mission. But the traditional rocket is inefficient and uneconomical, the more economical space launch approach has been studied in recent years. Two-Stage-To-Orbit(TSTO) reusable launch configuration which is combined Turbine Based Combined Cycle (TBCC) with reusable rocket (RR) is one of the main trends of current research. Based on TBCC-RR approach, a new design was proposed to improve the carrying capacity. In this design, the electromagnetic propulsion system (EMPS) was applied to increase the initial speed as the first stage engine, leaving the TBCC-RR to take care of the rest launch job. The overall concept of To-Orbit system was constructed and the electromagnetic launch system model was established. Then the mathematic model of EMPS-TBCC-RR-To-Orbit system is simulated and calculated. The result shows that EMPS is capable of accelerating the vehicle, which weighs hundreds of tons, up to one hundred meters per second, using EMPS can reduce the takeoff weight of the spacecraft and significantly enhance the carrying capacity of the spacecraft. Therefore, it is foreseeable that EMPS has a certain potential in the future space launch mission.

Title: Tracking and Vibration Control of Flexible Ball Screw Drive System Using a Parallel Structure Controller
Abstract: This paper presents a parallel structure controller for flexible ball screw drive systems with dynamic variations, which are mainly caused by variations of table position and workpiece mass. The controller consists of two parts. The linear quadratic regulator (LQR) controller aims at tracking reference trajectories with high response and accuracy. The interpolated gain-scheduled controller is used to suppress the system vibration. To damp out the varied resonant modes, the controller is obtained by a set of μ-synthesis linear time-invariant (LTI) controllers interpolated via Youla parameterization. The comparison experiments are conducted on the ball screw drive experimental setup to confirm the performance of proposed controller. It is demonstrated that the parallel structure controller achieves high performance in tracking, vibration suppression and disturbance-rejection.

Title: A Fast-Lock Low-Jitter PLL Based Adaptive Bandwidth Technique
Abstract: An adaptive-bandwidth phase-locked loop (PLL) presented in this paper is a multi-function, general purpose frequency synthesizer. Ultra-wide input and output ranges along with best-in-class jitter performance allow the PLL to be used for almost any clocking application. To reach wide output range and optimal jitter performance, adaptive bandwidth technique is applied to guarantee the stability of the loop. Furthermore, a fast-lock circuit is used to improve locking speed. The PLL is implemented in a 65nm CMOS process, while the core occupies 0.05mm2 and measurement results shows that the adaptive bandwidth PLL can generate clock with frequency from 200MHz to 1.6GHz. The measurement results also show good robustness of the PLL over temperature and supply voltage variation. The measured RMS jitters at 1.6GHz is less than 0.8ps when the supply noise under the 1% of itself. The fast-lock process lasts less than 3us, and the complete lock time is determined as 1000 input cycles.
