Land surface dynamics: A Multiphysics Approach to Modeling Mass Transport
Abstract: Land surface dynamics are governed by complex interactions among hydrological, atmospheric, and geomorphological processes that collectively drive the transport of mass across terrestrial environments. Traditional modeling approaches often isolate individual mechanisms, limiting their ability to capture the coupled feedbacks that shape landscape evolution. This study presents a multiphysics framework for modeling mass transport on land surfaces, integrating fluid flow, sediment transport, heat exchange, and chemical reactions within a unified computational …

Thermal Effects in High-Power Laser Systems: Modeling and Mitigation
Abstract: High-power laser systems are increasingly employed in industrial manufacturing, defense, medical procedures, and scientific research due to their ability to deliver high energy density with excellent spatial coherence. However, the performance and reliability of these systems are significantly influenced by thermal effects arising from optical absorption, non-radiative recombination, and inefficient heat dissipation within laser gain media and optical components. These thermal phenomena lead to adverse effects such as thermal lensing, …

MATLAB Simulation of Partial Power Converter with Dual- Mode Inverter for Solar Conversion
Abstract: The growing insertion of solar photovoltaic (PV) systems in the modern power systems requires high-efficiency, compact and reliable power conversion solutions. The traditional PV conversion system generally uses full-power processed DC-DC converters followed by inverters, which increases conduction and switching power losses, especially at higher power ratings. To overcome these challenges, this paper proposes a partial power processed resonant converter with a dual-mode transformer-less inverter for efficient solar PV power …

Influence of wall friction on Active Earth Pressure in Model Test
Abstract: Earth pressure theories occupy a paramount position in the field of geotechnical engineering. The knowledge of active earth pressure under static condition is essential in designing a retaining wall as the damage to such retaining structures may lead to disastrous failure. A retaining wall helps in maintaining the ground surface at different elevations on either side of it. Without such a structure, the soil at higher elevation would tend to …

Assessing the Influence of Loading Mode and Stabilization on the Deformation of Gypseous soil
Abstract: Gypseous subgrade soil usually exhibit acceptable strength when compacted with optimum moisture requirement and tested in dry condition. However, it loses its strength when came in touch with water. Such behaviour possesses a risk of failure when such soil is implemented in the construction of roadway embankment. In the present investigation, Gypseous soil was implemented in the construction of eight embankment models. The first model was the soil tested in …

Evaluation of Options using The Cox-Ross-Rubinshtein Mathematical Model
Abstract: Using complex mathematical formulas, we can calculate the reasonable value of an option.The Cox-Ross-Rubinstein model takes into account factors that are not considered in the Black-Scholes model and is an improved version of the binomial model. At the same time, the Cox-Ross-Rubinshtein model gives results close to the Black-Scholes model. The difference between these two models is that the Cox Ross Rubinstein modeltakes into account the possibility of early execution …

Structure based pharmacophore Modelling of compounds against Neurodegenerative disorder – Amyotrophic Lateral sclerosis
Abstract: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease characterized by the progressive degeneration of motor neurons, leading to muscle dysfunction, paralysis, and eventually death. These diseases are classified as ALS variations because autopsies reveal abnormalities in both upper and lower motor neurons. These disorders account for only 10% of all adult-onset motor neuron disease cases. Despite extensive research efforts, effective therapeutic interventions for ALS remain limited. Structure-based pharmacophore modeling …
