Valorization of Shrimp shells and Agricultural Wastes for Sustainable Biopolymer-Based Packaging Solutions
Abstract This research project focused on the valorization of shrimp shell and agricultural waste materials, such as rice straw, for the development of sustainable biopolymer-based packaging solutions. The key objectives were to extract and optimize chitosan and other biopolymers from shrimp shells, and to reinforce these materials with chitin fibers and whiskers for enhanced mechanical and

Using Piezoelectric textile insets to analyse working environment ergonomics
Abstract "The working environment is usually assessed through ergonomic analyses to determine the fatigue level of the labors subjected to long work. The CAD software helps in this field by using the built-in manikin that can be manipulated to reach the different gestures that the labor may show during the working day and determine fatigue levels through the RULA and REBA analyses. The utilization

One-dimensional nonlinear model of generalized thermo-electro elasticity.
Abstract We investigate a one-dimensional nonlinear model of thermo-electroelasticity in extended thermodynamics and quasi-electrostatic regime, with thermal conductivity and relaxation time dependent on temperature and heat flux. The aim is to assess the effect of quadratic nonlinear couplings between mechanical, thermal, and electric fields, known to impact solution stability. Two wave

Novel Concept-based Image Captioning Models using LSTM and Multi-Encoder Transformer Architecture
Abstract Captioning images involves using vision and language models to describe images concisely. Successful captioning requires extracting key information, including the image's topic. While state-of-the-art methods use topic modeling on caption text, this lacks consideration of the image's semantic information. Concept modeling, which extracts concepts directly from images and caption text, can

Prediction and mitigation of common steam line hanger failures
Abstract Repeated hanger failures were observed in the steam condenser reject lines of a multi-unit nuclear power station, attributed to shear fractures of the threaded end of the hanger rods. The failures occurred at the same location in the piping run, near a reducer and an elbow where the stream flow changes direction. While condensed steam water slug impact is a possibility, the primary cause

Prediction of flow-excited acoustic resonance in coaxial burners
Abstract In this project, numerical analysis models acoustic modes in cavities. Different cavities with various aspect ratios are used. The square cross-section cavity created a spinning mode. However, a small change from the square configuration created an attenuation of the amplitude, which impacts the mode. More importantly, the shear layer changed according to the acoustic mode behavior such
