Topic: High-Capacity Inter-building Bi-directional Optical Wireless Transmission in 1.55 μm Band

Abstract: Fiber optics communication has become an important research issue in recent decades thanks to its very wide bandwidth and high-speed communications services. Free space optic (FSO), sometimes called optical wireless communication (OWC) has undergone through cycles of technical evolutions mainly due to the remarkable development in light sources and optical receiver technologies. Nowadays FSO links with Gbit/s or above per channel have been reported for outdoor and indoor applications. 
In this talk, I will propose and investigate a free space optic transmission system in inter buildings transmission and cross-bridge transmission. The harsh environmental factors for FSO including window glasses, air turbulence and rain drop, will also be studied and verified. The proposed scheme, may have some merits over conventional fiber-based communications, can also play as a back-up methodology in emergency case to ensure seamless communications.

Topic: Novel Types of AC Motors and Drives for Electrical and Hybrid Vehicles

Abstract: The novel types of AC motors and drives for electrical and hybrid vehicles were worked out by the authors of this paper. These types are based on the use of the phase-pole-controlled multiphase (i.e. having number of phases more than four) inverter-fed linear stators. The phase-pole-control method is novel method of electromechanical systems control. It was developed by the author a few years ago for multiphase AC electric drives and molten metals electromagnetic stirring systems.
The application of phase-pole-control method together with the increase of drive system phase number more than four allows to improve considerably a number of the drive technical-and-economic characteristics (such as speed of response, reliability, mass-and-overall dimensions, etc.).

Topic: Renewable Energy Systems: Technologies and Applications for Future Electric Grid

Abstract: Renewable energies can substantially improve the increasing energy demands and mitigate greenhouse gas emissions. It also provides direct and indirect social benefits such as reducing the health and environmental impacts associated with the use of fossil and nuclear fuels, thereby improving standard of living, educational opportunities, creating jobs, reducing poverty, increasing gender equality and ensures energy security. Hybrid renewable energy systems comprising of solar and wind will be effective for efficient power generation, in spite of variability, intermittency and other grid related issues. Prospects and insights of solar photovoltaic and wind energy systems will be discussed by analyzing information reported in various literatures, government and international renewable energy agencies. Also policies and initiatives related to hybrid energy systems concerning environment and economy will be addressed. The progressive path for renewable energy development will be suggested through increased use of renewable energy generation with enhanced reliability, security and resiliency of the future electric grid.

Topic: Thermal-Electrical-Mechanical-Metallurgical Controlling of Resistance Spot Welding

Abstract: The present work quantitatively predicts transport processes in workpieces coupled with electrode containing a coolant hole during the entire range of resistance spot welding. Understanding of transport processes is essentially required for controlling the critical defect of surface melting and microstructures of weld nugget. This model realistically accounts for transient electromagneto-fluid mechanics, heat and species transport, and bulk resistance in workpiece, and film and constriction resistances at contact interfaces. In view of finite electrical diffusion of ferromagnetic materials, time delay of electric current density associated with joule heat should also be accounted for. The results find and confirm the factors affecting the defect of surface melting and different modes of microstructures of the weld nugget.
