Directional Modulation With Cooperative Receivers

IEEE Access, 2018
Directional modulation (DM) refers to a class of efficient techniques for enhancing the physical layer security of wireless communications. However, conventional DM approaches cannot guarantee the transmission security when eavesdroppers are located ...

Hong Kong's non‐local undergraduate recruitment: Policies, institutional practices and student perspectives

British Educational Research Journal, EarlyView.
Abstract Beneath the Hong Kong government's enthusiasm for recruiting non‐local undergraduates—including students from the Chinese Mainland and other international regions—lies a longstanding gap in understanding the core meanings and drivers shaping the territory's expanding focus on inward international student mobility (ISM).

Virtual Induction Loops Based on Cooperative Vehicular Communications

Sensors, 2013
Induction loop detectors have become the most utilized sensors in traffic management systems. The gathered traffic data is used to improve traffic efficiency (i.e., warning users about congested areas or planning new infrastructures).

Coherent versus non-coherent decode-and-forward relaying aided cooperative space-time shift keying

, 2011
Motivated by the recent concept of Space-Time Shift Keying (STSK), we propose a novel cooperative STSK family, which is capable of achieving a flexible rate-diversity tradeoff, in the context of cooperative space-time transmissions. More specifically, we

Cramér-Rao Bound for Hybrid GNSS-Terrestrial Cooperative Positioning [PDF]

, 2010
In this contribution we derive an expression of the Cramer-Rao bound for hybrid cooperative positioning, where GNSS information is combined with terrestrial range measurements through exchange of peer-to-peer messages. These results provide a theoretical

Form flows function: Learner‐centered game Re‐design in a STEM classroom

British Educational Research Journal, EarlyView.
Abstract Re‐designing games facilitates interest‐driven learning and immerses learners in systems thinking. However, there are limited studies exploring how the form and function of tabletop games influence learners' design decisions and learning experiences. To address this gap, we conducted a mixed‐methods study in a STEM classroom in western Canada.

Beyond standardisation, subjects and syllabi: How primary schools organise for arts richness in an era of curriculum reform

British Educational Research Journal, EarlyView.
Abstract As England embarks on its first comprehensive curriculum review in fifteen years, this paper offers critical insights from schools that sustained arts‐rich provision despite a policy landscape hostile to creative subjects. Drawing on data from the Researching Arts‐rich Primary Schools (RAPS) project—a mixed‐methods study of 76 arts‐rich ...

Harnessing blood clot as a native scaffold for orchestrating tissue repairs and regeneration

BMEMat, EarlyView.
The blood clot, owing to its dynamic composition and unique microenvironment, holds significant yet underappreciated potential for tissue engineering. This review systematically summarizes the pathophysiology of clot formation, the key regulatory factors shaping its microenvironment, and its applications in both pre‐clinical and clinical settings ...
