Analytical expressions for the concentration of nitric oxide removal in the gas and biofilm phase in a biotrickling filter

Muthuramalingam, Rasi; Kumar, Sunil; Lakshmanan, Rajendran (2015)

In this paper, a mathematical model of nitric oxide removal using biotrickling filter (BTF) packed with uniform ceramic particles under thermophilic condition is discussed. The model proposed here is based on the mass ...
A Fast Keypoint Based Hybrid Method for Copy Move Forgery Detection

Kumar, Sunil; Desai, J.V; Mukherjee, Shaktidev (2015)

Copy move forgery detection in digital images has become a very popular research topic in the area of image forensics. Due to the availability of sophisticated image editing tools and ever increasing hardware capabilities, ...
A fractional model of Navier–Stokes equation arising in unsteady flow of a viscous fluid

Kumar, Devendra; Singh, Jagdev; Kumar, Sunil (2015)

In this paper, we present a reliable algorithm based on the new homotopy perturbation transform method (HPTM) to solve a time-fractional Navier–Stokes equation in a tube. The fractional derivative is considered in the ...
Fractional modelling for BBM-Burger equation by using new homotopy analysis transform method

Kumar, Sunil; Kumar, Devendra (2014)

The purpose of this study is to introduce a new analytical method namely, fractional homotopy analysis transform method (FHATM) for series solution of the time fractional BBMBurger equation. The homotopy analysis transform ...
Improved YOLOv4 Approach: A Real Time Occluded Vehicle Detection

Kumar, Sunil; Jailia, Manisha; Varshney, Sudeep (2022-08-06)

A major challenge in computer vision is detecting and tracking vehicles in real-time. However, existing algorithms fail to detect vehicles at high speeds and accuracy. Therefore, an algorithm that detects vehicles with ...
Numerical computation of fractional multidimensional diffusion equations by using a modified homotopy perturbation method

Kumar, Devendra; Singh, Jagdev; Kumar, Sunil (2015)

The main aim of the present work is to present a numerical algorithm for solving fractional multi-dimensional diffusion equations which describes density dynamics in a material undergoing diffusion by using a modified ...
