14:00 pm

SIST 1C-101

Speaker:Kejun Tang,Great Bay University.Time: 14:00pm, Apr.18th.Location:SIST 1C-101Host: QifengLiaoAbstract:The committor functions are central to investigating rare but important events in molecular simulations. It is known that computing the committor function suffers from the curse of dimensionality. Recently, using neural networks to estimate the committor function has gained attention due to its potential for high-dimensional problems. Training neural networks to approximate the committor

SIST 2-215

Speaker:Shihao Yan,Edith Cowan University.Time: 10:00am, Apr.17th.Location:SIST 2-215Host: YongZhouAbstract:This work develops a two-phase secure integrated sensing and communication (ISAC) framework, where a dual-function transmitter (Alice) detects the presence of a potential eavesdropper (Eve) as a sensing target in the first phase. In the second phase, Alice adapts her secure transmission strategy based on the sensing outcome of the first phase. A distinct aspect of our developed two-phase

SIST 1A-200

Speaker:ZhiqiangDuanTime: 14:00, Mar.27Location:SIST 1A-200Host: Yu LiuAbstract:At present, the main goal of the new power system is to gradually replace fossil energy with renewable energy such as wind power and solar power. However, wind power, photovoltaic and other renewable energy systems are mainly based on power electronic control, and their system inertia is smaller than that of traditional power generation. At the same time, it also has strong volatility and randomness, and large-scale
