Title: Strain modulated nanomaterials with applications electronic
and photonic systems
Abstract:
With rapid development of communication systems such as 5G, the demand for superior performance electronic and photonic devices has been extremely high. Traditional devices might not meet the request of the fast grow of the communication technologies. With this context, many international researchers have turned their research and development focuses onto nanoscale materials and devices particularly with unprecedented discoveries on the topological effects and superconductivities. In this talk, a brief review on the state-of-the-art of the nanoscale materials and devices modulated with mechanical strains, which potentially demonstrate promising improvements on electronic and photonic properties is presented. As well as discussions on the applications of those strain modulated nanomaterials and devices will be made on this conference. The presentation is expected to serve as a stimulator to promote future novel research and development on this ever-intriguing topic.

Title: From Group Role Assignment (GRA) to GRA with Constraints
(GRA+) and GRA with Multiple Objectives (GRA++)
Role-Based Collaboration (RBC) has been proposed as an emerging and promising approach to facilitating collaboration. It utilizes roles as underlying mechanisms to support collaboration by taking advantage of roles. It is divided into several phases: role negotiation, role assignment, and role play.
In dealing with GRA, there are many constraints we need to consider. These constraints come from future role execution, including conflicts, cooperation, limitations, preferences, and feasibility. Solutions to the GRA with constraints (GRA+) problems can be more easily applied to industrial applications. After more constraints are discussed, multiple objective problems are revealed for GRA and GRA+. Such problems are called GRA with Multiple Objectives (GRA++)
This talk introduces the concepts of Role-Based Collaboration and the E-CARGO (Environment – Classes, Agents, Roles, Groups, and Objects) model, clarifies the group role assignment problems (GRA, GRA+, and GRA++) by examples and formalizations, discusses the solutions, and presents the recent research results.
