Streaming Codes for Low-Latency Communication over Various Sliding-Window Channel Models
Streaming codes are packet-level codes that recover dropped (i.e., erased) packets within a decoding-delay deadline. A common model for packet erasures over a network is the Markov, two-state Gilbert-Elliott (GE) channel ... -
Remediation of Heavy Metal Contaminated Soil and Sediment And its Effective Reuse in Construction
This research explores approaches to mitigate the environmental impact of heavy metal contamination in soil and dredged sediment. It focuses on three main areas: chemical remediation through nano zero-valent iron (nZVI), ... -
Non-linear Hall Effect in Two- and Three-dimensional Materials
Underpinned by the concept of Berry curvature in band theory, the family of classical and quantized Hall effects are conventionally observed in the linear response regime. A measurable Hall response requires the time-reversal ... -
Behaviour Modelling of Non-Cooperative Space Objects and Strategies for Decision Support in Space Situational Awareness
Space Situational Awareness [SSA] is defined as the comprehensive knowledge of Resident Space Objects [RSO] which may include satellites, rocket bodies, debris etc. and the ability to understand their behaviour. SSA solutions ... -
