A Blockchain-Based Self-Tallying Voting Protocol In Decentralized Iot, Yannan Li, Willy Susilo, Guomin Yang, Yong Yu, Dongxi Liu, Xiaojiang Du, Mohsen Guizani

Research Collection School Of Computing and Information Systems

The Internet of Things (IoT) is experiencing explosive growth and has gained extensive attention from academia and industry in recent years. However, most of the existing IoT infrastructures are centralized, which may cause the issues of unscalability and single-point-of-failure. Consequently, decentralized IoT has been proposed by taking advantage of the emerging technology called blockchain. Voting systems are widely adopted in IoT, for example a leader election in wireless sensor networks. Self-tallying voting systems are alternatives to unsuitable, traditional centralized voting systems in decentralized IoT. Unfortunately, self-tallying voting systems inherently suffer from fairness issues, such as adaptive and abortive issues caused …

Automating App Review Response Generation Based On Contextual Knowledge, Cuiyun Gao, Wenjie Zhou, Xin Xia, David Lo, Qi Xie, Michael R. Lyu

Research Collection School Of Computing and Information Systems

User experience of mobile apps is an essential ingredient that can influence the user base and app revenue. To ensure good user experience and assist app development, several prior studies resort to analysis of app reviews, a type of repository that directly reflects user opinions about the apps. Accurately responding to the app reviews is one of the ways to relieve user concerns and thus improve user experience. However, the response quality of the existing method relies on the pre-extracted features from other tools, including manually labelled keywords and predicted review sentiment, which may hinder the generalizability and flexibility of …

Preparing Providers For Advanced Life Support In The Prehospital Environment, David N. Reid

Theses: Doctorates and Masters

Out-of-hospital cardiac arrest is a leading cause of death and Ambulance Victoria estimated over 30,000 cardiac arrests occur outside of hospital each year in Australia (1, 2). When an out-of-hospital cardiac arrest occurs, first responders, paramedics or other clinicians attached to ambulance, industrial or aeromedical services are often the first providers on scene with the skills and equipment to implement advanced life support (ALS). Despite the essential role of prehospital advanced emergency care in the treatment of out-of-hospital cardiac arrest, at the time this research was commenced, ALS training courses had been designed for those responding to cardiac arrests in …

Mind The Gap: Reimagining An Interactive Programming Course For The Synchronous Hybrid Classroom, Christopher M. Poskitt, Kyong Jin Shim, Yi Meng Lau, Hong Seng Ong

Research Collection School Of Computing and Information Systems

COVID-19 has significantly affected universities, forcing many courses to be delivered entirely online. As countries bring the pandemic under control, a potential way to safely resume some face-to-face teaching is the synchronous hybrid classroom, in which physically and remotely attending students are taught simultaneously. This comes with challenges, however, including the risk that remotely attending students perceive a ‘gap’ between their engagement and that of their physical peers. In this experience report, we describe how an interactive programming course was adapted to hybrid delivery in a way that mitigated this risk. Our solution centred on the use of a professional …

A Feasibility Assessment Of The Optimal Use Of Hydrogen Drones In Fashion Item Replenishment Logistics, Chi Wing, Alex Tsang

Department of Construction, Environment and Engineering

What should be considered in optimising the delivery routes for stock replenishment in a retail textile company? Traditional land-based truck delivery makes prompt returned or new products replenishments in small batches from one location to another impractical due to the high shipping costs incurred. Drones, which serve as digitized delivery equipment especially in western countries nowadays, realise last-mile and door-to-door deliveries. Breaking geographical barriers, drones raise operational efficiency and lower human- and equipment-related costs. Nonetheless, drone delivery regulations set legal boundaries. Added to this are the teething issues arisen in the drone deliveries across regulatory borders. As a consequence, retail …

Delta Debugging Microservice Systems With Parallel Optimization, Xiang Zhou, Xin Peng, Tao Xie, Jun Sun, Chao Ji, Wenha Li, Dan Ding

Research Collection School Of Computing and Information Systems

Microservice systems are complicated due to their runtime environments and service communications. Debugging a failure involves the deployment and manipulation of microservice systems on a containerized environment and faces unique challenges due to the high complexity and dynamism of microservices. To address these challenges, we propose a debugging approach for microservice systems based on the delta debugging algorithm, which is to minimize failure-inducing deltas of circumstances (e.g., deployment, environmental configurations). Our approach includes novel techniques for defining, deploying/manipulating, and executing deltas during delta debugging. In particular, to construct a (failing) circumstance space for delta debugging to minimize, our approach defines …
