Existence and density conservation using a non-conservative approximation for Safronov-Dubovski aggregation equation
Sonali Kaushik, Rajesh Kumar
The paper deals with the global existence and density conservation for the Safronov-Dubovski equation for three different coefficients such that $ϕ_{i,j} \leq \frac{(i+j)}{\min…
Convergence and error analysis for pure collisional breakage equation
Sanjiv Kumar Bariwal, Ankik Kumar Giri, Rajesh Kumar
Collisional breakage in the particulate process has a lot of recent curiosity. We study the pure collisional breakage equation which is nonlinear in nature accompanied by locally b…
GANTouch: An Attack-Resilient Framework for Touch-based Continuous Authentication System
Mohit Agrawal, Pragyan Mehrotra, Rajesh Kumar +1
Previous studies have shown that commonly studied (vanilla) implementations of touch-based continuous authentication systems (V-TCAS) are susceptible to active adversarial attempts…
iCTGAN--An Attack Mitigation Technique for Random-vector Attack on Accelerometer-based Gait Authentication Systems
Jun Hyung Mo, Rajesh Kumar
A recent study showed that commonly (vanilla) studied implementations of accelerometer-based gait authentication systems (ABGait) are susceptible to random-vector attack. The sa…
Numerical analysis for coagulation-fragmentation equations with singular rates
Sanjiv Kumar Bariwal, Prasanta Kumar Barik, Ankik Kumar Giri +1
This article deals with the convergence of finite volume scheme (FVS) for solving coagulation and multiple fragmentation equations having locally bounded coagulation kernel but sin…
A Novel Optimized Decomposition Method for Smoluchowski's Aggregation Equation
Sonali Kaushik, Rajesh Kumar
The Smoluchowski's aggregation equation has applications in the field of bio-pharmaceuticals \cite{zidar2018characterisation}, financial sector \cite{PUSHKIN2004571}, aerosol scien…
Theoretical analysis of a discrete population balance model for sum kernel
Sonali Kaushik, Rajesh Kumar, Fernando P. da Costa
The Oort-Hulst-Safronov equation, shorterned as OHS is a relevant population balance model. Its discrete form, developed by Dubovski is the main focus of our analysis. The existenc…
Existence and Uniqueness of Mass Conserving Solutions to Safronov-Dubovski Coagulation Equation for Product Kernel
Sonali Kaushik, Rajesh Kumar
The article presents the existence and mass conservation of solution for the discrete Safronov-Dubovski coagulation equation for the product coalescence coefficients such that…
