Overcoming Tight Constraints in Soft Happy Colouring
Mohammad Hadi Shekarriz, Asef Nazari, Dhananjay Thiruvady
The Soft Happy Colouring (SHC) problem, a mathematical framework for identifying homophilic network structures, seeks to maximise the number of -happy vertices, i.e., vertices…
Multiobjective Model Predictive Control for Residential Demand Response Management Under Uncertainty
Guan-Ting Lin, Wei-Yu Chiu, Chien-Feng Wu +2
Residential users in demand response programs must balance electricity costs and user dissatisfaction under real-time pricing. This study proposes a multiobjective model predictive…
Finding happiness by evolutionary algorithms
Mohammad Hadi Shekarriz, Dhananjay Thiruvady, Asef Nazari
A recent line of research concerns the problem of soft happy colouring (SHC), which requires that a partially coloured graph be extended to a complete colouring to maximise local a…
Audio Physical Dynamics Inspired Deepfake Detection for Voice Authentication Systems
Alireza Mohammadi, Keshav Sood, Dhananjay Thiruvady +1
Voice authentication systems deployed at the network edge face dual threats: a) sophisticated deepfake synthesis attacks and b) control-plane poisoning in distributed federated lea…
Causal Modelling of Cryptocurrency Price Movements Using Discretisation-Aware Bayesian Networks
Rasoul Amirzadeh, Asef Nazari, Dhananjay Thiruvady +1
This study identifies the key factors influencing the price movements of major cryptocurrencies, Bitcoin, Binance Coin, Ethereum, Litecoin, Ripple, and Tether, using Bayesian netwo…
A Bi-Objective Mathematical Model for the Multi-Skilled Resource-Constrained Project Scheduling Problem Considering Reliability: An AUGMECON2VIKOR Hybrid Method
Mohammad Ghasemi, Asef Nazari, Dhananjay Thiruvady +3
In recent years, resources with multiple skills have received attention as an extension of the resource-constrained project scheduling problem known as MSRCPSP. Although the disrup…
