During the COVID 19 pandemic, the importance of global academia-industrial alliances has increased. It is hoped that the alliances will help us to solve the current problems caused by the pandemic. In this paper, we introduce the application of IT tools and communication skills utilized in a special educational project for an academia-industrial collaboration. Some concrete examples from 2020 are provided from the viewpoint of the national alliance project in Japan. A discussion is included that describes the plans available to increase and strengthen the national project in the future. [ABSTRACT FROM AUTHOR]

• Ground response mechanism under different geometrical configurations of jacked rectangular pipe was investigated. • Higher jacking force is needed with increasing aspect ratio of the jacked rectangular pipe. • Square shaped cross-section design is conductive for deep and long-distance jacking construction. For rectangular pipe-jacking construction, the primary priorities of smooth construction include minimizing the ground response and designating the appropriate jacking force to achieve the best results in environmental protection and energy conservation. The geometric cross-section design of the jacking rectangular pipe and its engineering performances such as the ground surface displacement, the jacking force consumption, and the stress-bearing state are easy to be ignored in the field construction. In this paper, the ground response characteristics under four kinds of rectangular pipe aspect ratio (H/W) with the same utilization cross-section area were investigated by using the calibrated finite element method (FEM) based on a case study conducted in Japan. The theoretical jacking force of each pipe section design was calculated and compared to provide a reference for long-distance or large-section jacking conditions. The stress-bearing state of each pipe was considered under different buried depths. The results show that the ground surface response decreases while the jacking force increases with increasing the aspect ratios. Thus, a reasonable design of the rectangular pipe section should comprehensively consider the influence of geometric effects on the ground and its stress-bearing state during the jacking construction. The findings of this study provide a practical reference for the safe and economic design of the jacking rectangular pipe and engineering management. [ABSTRACT FROM AUTHOR]

Abstract: This paper presents activities of the Architectural Institute of Japan (AIJ) on computational wind engineering, focusing on numerical prediction of wind loads on buildings. It discusses and evaluates current CFD techniques, including LES and modified RANS, for wind-resistant design of actual buildings. It also provides a guide for constructing a numerical model, including selection of a turbulence model, size of computational domain, required numerical discretization, etc. [Copyright &y& Elsevier]

Abstract: The ITER transitional arrangements (ITA) is conducted by the International Team (IT) with supports from participant teams (PTs). The Japanese Participant Team (JA-PT) has contributed to the ITA by sharing a lot of technical tasks to verify feasibilities of fabrication and quality control method in procuring ITER equipments and facilities. For examples, trial fabrications of Nb3Sn strands have been performed by the JA-PT with four potential suppliers, and it has already been confirmed that one of the strands produced by a certain supplier meet the ITER requirements. All strands produced by other suppliers will be fully qualified by the end of 2005. The trial fabrications of jackets for the central solenoid (CS), structural material for toroidal field coil, the partial mock-ups of the vacuum vessel (VV) and the shield blanket module are also ongoing to verify the feasibility of fabrications and quality inspections. Furthermore, the JA-PT has made several technical developments on neutral beam (NB) system to improve reliability in high voltage (1MV) insulation and in stable high current density operations over a long period. Design of equatorial EC launcher and some techniques towards reliable steady-state EC operation have been developed. The paper also describes other activities to confirm validity of the present design. [Copyright &y& Elsevier]
