Study on the Method of Prediction of Complete Inflation Time of Parachute
Abstract: In general, the parachute test is a long test period, expensive, and difficult to measure with accuracy, which makes it a very laborious and laborious task due to the strong nonlinearity of the fabric of the parachute. Therefore, attempts have been made to overcome this by using a parachute testbed or by simulation, but in our country, there is no numerical simulation of the parachute, and no research has been …

Biodegradable Polymer Composite Materials for Long-Term Drug Release in Pharmacotherapy
Abstract: Biodegradable Polymer composite materials are a promising choice for controlled drug delivery because they let medicine be released slowly over time during treatment. These structures, which are made from safe, recyclable plastics, work well to make sure that drugs stay in the body for a long time. This means that patients will take their medicine less often and more consistently. As the body breaks down these structures, the drug inside …

Water Spread Area Dynamic of Chilika Lake: A Geospatial Approach
Abstract: Chilika lake is the largest lagoon in Asia on the east coast peninsular India covering about hundred thousand hectares of land, one among six Indian wetlands declared under the Ramsar convention in 1982. Lake shrinkage is another important ecological transformation. This may be due to several factors, both natural and human. The study area is Chilika Lake which is located at 19°27’58.081”N–19°53’24.438”N latitude and 85°6’5.301”E–85°40’36.149”E longitude on the east-coast of …

Oceanmind Systems: AI-Driven Marine Life Intelligence for Climate Prediction and Ocean Ecosystem Stability
Abstract: Oceans regulate global climate systems, support biodiversity, and serve as critical carbon sinks, yet they remain under-monitored relative to their ecological importance. Traditional oceanographic methods rely heavily on satellite sensing, buoy networks, and periodic marine surveys, which often fail to capture real-time biological dynamics at micro-ecosystem levels. This paper introduces OceanMind Systems, an artificial intelligence (AI)-driven marine intelligence framework that integrates marine life behavior, oceanographic data, and computational modeling to …
