Project Title

INTACT: Intelligent Tropical-storm-resilient System for Coastal Cities

Abstract

Ongoing population growth and the impact of climate change pose heightened risks of typhoon and tropical storm-related hazards in coastal cities. Hong Kong was hit by Super Typhoon Mangkhut in 2018, causing significant disruption to the safety of the city and well-being of residents.
The objective of this project is to minimize the losses caused by typhoons by establishing an intelligent tropical-storm-resilient system for coastal cities. The project will devise a framework that enables efficient and accurate assessment of turbulence flows from sparse measurements. It will also quantify urban-environment tropical storm risks that arise due to complex urban aerodynamics.
The project will establish a real-time urban typhoon risk early-warning and management prototype that will be made accessible to the public for guiding effective emergency responses, such as evacuation measures and the temporary reinforcement of glass panels. The project outcomes will also lead to new methodologies and design codes/standards for high-rise buildings that are more resistant to tropical storms. This will in turn create a safer environment, benefiting the construction industries and developers, public and city planners in the long run.
The fundamental scientific discoveries and technologies developed for Hong Kong’s complex urban environment will have easy transferability to other cities, including those in the GBA, and can serve as case models for global reference.

Project Title

High-performance Collaborative Edge Computing Enabling Smart City Applications: Framework and Methodologies

Abstract

Existing edge computing projects focus on vertical collaboration among cloud, edge and end devices while neglecting horizontal edge-to-edge collaborations, which leads to unoptimised resource utilisation, restricted service coverage and uneven performance. This project aims to build a new smart city computing infrastructure enabled by collaborative edge computing with edge/cloud collaboration, city-scale edge network deployment and built-in AI services.
The Collaborative Edge Computing Framework (CECF) proposed by this project aims to construct a future ubiquitous computing infrastructure by connecting, sharing and managing the resources of a large number of edge nodes. CECF provides new abstractions and functionalities for geo-distributed edge nodes to share computing and data resources and collaborate to perform application tasks, enabling advanced smart city applications.
The project addresses many key challenges, including large-scale resource management, performance-guaranteed task scheduling, resource-aware edge AI and secure data sharing. It will ultimately enable emerging advanced smart city applications to flourish in HK and establish a first-mover advantage for the City in new computing infrastructure.
