ORAL PRESENTATIONS

1. Estimation of Paracetamol in Intact Tablets Using Near-Infrared Spectroscopy and Artificial Neural Networks
   Rajib Bandyopadhyay, Dilip Sing, Subhadip Banerjee, Arbab Mahtab, Soumitra Das Mahapatra, Ajanto Kumar Hazarika

   • Focuses on the integration of NIRS with Artificial Neural Networks (ANN) for non-destructive, rapid quantification of paracetamol content in tablets.

2. Application of Near-Infrared Spectroscopy for Estimation of Lignin Content in Jute
   Dilip Sing, Pratik Satya, Tinku Goswami, Sonu Kumar, Rajib Bandyopadhyay

   • Utilizes PLSR and advanced preprocessing techniques (SNV and second-order derivatives) to predict lignin content in jute for quality and application-specific fiber characterization.

POSTER PRESENTATIONS

3. Rapid Quantification of Toxic Diethylene Glycol (DEG) Contaminant in Glycerin-Based Cough Syrup Using NIR Spectroscopy
   Rajib Bandyopadhyay, Dilip Sing, Deba Prasad Kanshari, Surojyoti Mandal, Uday Pratap Sing, Soumitra Das Mahapatra, Ajanto Kumar Hazarika

   • Highlights a fast and portable NIR method to detect DEG contamination in pharmaceutical syrups, a critical public health concern.

4. Transformer-Based Model for NIR Data: Estimation of Quinine Content in Cinchona
   Dilip Sing, Masudul Islam, Uden Angmu Yonzone, Samuel Rai, Rajib Bandyopadhyay

   • Presents a novel approach using deep learning transformer models on NIR spectra to assess medicinal content in cinchona bark.

5. Rapid Quality Evaluation and Market Valuation of Crush Tear Curl (CTC) Black Tea Using Near Infrared Spectroscopy
   MetaspeQ Team

   • Demonstrates how NIRS can assist in real-time tea grading and pricing, offering a digital solution for tea auction and quality control platforms.
