Title: Urban Energy Resilience for Climate Change Adaptation and Mitigation
Abstarct: Cities account for between 60% and 80% of the global energy consumption. Given the projected increase in world׳s urban population, this share is expected to further increase in the future. Continuity of energy supply in cities is affected by climate change and a growing array of other threats. Resilience thinking is an approach to management of socio-ecological systems that aims to develop an integrated framework for bringing together the (often) fragmented, diverse research on disaster risk management. This research provides a better understanding of the underlying principles of urban energy resilience and introduces a conceptual framework that can be used to assess urban energy resilience. In order to be resilient, urban energy systems need to be capable of “planning and preparing for”, “absorbing”, “recovering from”, and “adapting” to any adverse events that may happen in the future. This study introduces different planning and design criteria related to infrastructure, resources, land use, urban geometry and morphology, governance, and socio-demographic aspects and human behavior. In addition, through providing empirical insights from disaster-triggered urban energy initiative from around the world, this research clarifies the significance of characteristics such as efficiency, redundancy, robustness, diversity, coordination capacity, equity, and modularity for promoting urban energy resilience.

Title: Advances in the studies and control technologies of frost deposition on cold surface
Abstarct: Frost deposition is a very common phenomenon occurring on cold surfaces in both our daily lives and engineering applications. It can result in many serious negative effects on cryogenic equipment and systems, including flow passage blockage, poor heat transfer performance, pressure drop increase, low energy efficiency and even system malfunction. Therefore, frost deposition control is very important for the equipment and these systems and has been attracting huge attentions from both industries and scientists. In this talk, the frost formation fundamentals and the influences of cold surface characteristics (hydrophilicity and hydrophobicity) and external fields (electric and magnetic) are briefly reviewed and advances in frost deposition control including basic theory and various technologies are introduced in full length. The outlook for feasible frost deposition control technologies is presented.
