Reinforcement Learning-Based Bio-Inspired Control for Stability Enhancement in Autonomous Vehicles T. Venkatamuni, B Pavani Srikavya, S. Bathrinath, S. Gayathri Priya, M Pandikumar, Abhishek Kumar Jain 2026 Innovations in Machine Engineering and Digital Conference Imed 2026, 2026 The current paper proposes a support system to increasing the stability of autonomous vehicles by using the combination of reinforcement learning (RL) and bio-inspired control strategy. In particular, we suggest to utilize genetic algorithms to learn optimal control to RL so that the system is able to learn in changing road conditions and disturbances. The genetic algorithm aids in the search of the solution space which seeks the best performing policy to enhance the vehicle stability control. We use the CARLA simulator as an instrument to evaluate and verify the developed approach in a range of driving situations, in sharp turns and slippery roads. The stability aspect of our approach is much better as the response times and change of control was smoother than in the traditional methods. The findings suggest that RL coupled with bio-inspired optimization procedures provides a resilient adaptive solution to obtaining stability improvement in autonomous vehicles, and thus it is suitable to real life situations in autonomous driving systems.
Thermal characterization of hexagonal boron nitride/polyester composites for microelectronic applications Akash Kushwaha, Shailendra Bohidar, Abhilash Dahayat, Abhishek Jain, Prabhat Mishra, Payal Sonber, Rakshit Sisodiya Scienggj, 2025 In a world constantly seeking sustainable solutions, the quest for advanced materials with superior mechanical and thermal properties remains crucial. Composite materials have emerged as a promising avenue, blending the strength of traditional materials with innovative reinforcements, paving the way for applications ranging from aerospace to automotive industries. In this study, we embark on a comparative journey, delving into the world of composite materials by scrutinizing hexagonal boron nitride (hBN) reinforcements infused within a polyester matrix. This research explores the thermal attributes of these composites, illuminating their potential in various engineering applications. The composites’ thermal conductivity and glass transition temperature increase with hBN content, whereas the coefficient of thermal expansion decreases. Hexagonal boron nitride (hBN)-reinforced unsaturated polyester composites were prepared with untreated and silane-treated hBN fillers (10–40 wt%). Silane surface modification of hBN significantly improved filler dispersion and interfacial adhesion. The thermal conductivity of neat polyester (0.38 W/m·K) increased to 1.76 W/m·K with 40 wt% untreated hBN and to 2.16 W/m·K (a 568% enhancement) with 40 wt% silane-treated hBN. The percolation threshold decreased from ~32.5 wt% (untreated) to ~27.5 wt% (silane-treated). The glass transition temperature rose from 78°C (neat polyester) to 97.8°C (untreated hBN) and 103.5 °C (silane-treated hBN) at 40 wt% loading. The coefficient of thermal expansion decreased from 68 × 10⁻⁶/°C to 56.9 × 10⁻⁶/°C and 55 × 10⁻⁶/°C for untreated and silane-treated composites, respectively, at the same filler content. These improvements, achieved while maintaining good processability and a low dielectric constant, demonstrate the potential of silane-treated hBN/polyester composites for thermal management in microelectronic applications.
Characterization and Combustion Analysis of Densified Fuel Briquettes Made from Bio-Waste Materials † J. Parthipan, J. Jayaprabakar, Chandrashekhar Ghule, Sheik Hidayatulla Shariff, S. Baskar, Lim Jia Xuen, Nishikant Kishor Dhapekar, Abhishek Kumar Jain, Abhishek Sharma Engineering Proceedings, 2025 In this study, fallen leaves of Azadirachta indica and Prunus dulcis were treated as waste materials for the production of energy-intensive bio-coal briquettes. The physical composition revealed that the moisture content ranged from 6.8% to 8.8%, fixed carbon from 10.7% to 14.0%, volatile matter from 71.2% to 77.1%, and ash content from 4.1% to 7.6%. The chemical structure of the biomass fuel, which included carbon, hydrogen, nitrogen, sulfur, and oxygen, was noted to be 44.56–50.69%, 7.12–7.33%, 0.14–0.25%, 0.47–0.79%, and 41.08–47.46%, respectively. The higher heating value ranged from 16.8 to 18.3 MJ/kg. With increasing pressure from 5 to 20 MPa, briquette density increased from 654 to 995 kg/m3, shatter index from 81% to 94%, durability from 67% to 92%, and resistance to water penetration from 57% to 77%. A low-pressure briquette (5 MPa) burned at a higher rate of 8.0 g/min, whereas a high-pressure briquette (20 MPa) burned at a lower rate of 2.5 g/min. All leaf types tested were able to boil 1000 mL of water with 100 g of briquettes in just 7 min.

Experimental Study on Recycled HDPE and Waste Glass Powder Composite Material for Pipe Production Deepak Kumar Yaduwanshi, Nitin P. Gudadhe, Piyush Tiwari, Kidus Tesfay Areki, K. Logesh, et al. International Journal of Vehicle Structures and Systems, 2024 In Ethiopia, scraps of high-density polyethylene (HDPE) pipes and crushed glass bottles are largely considered waste and are not being recycled or reused. In this study, it is aimed at experimentally processing HDPE scrap and mixing it with waste glass powder to produce a composite material with the potential to become a matrix and reinforcement material for pipes. Six samples were produced with varying percentages of the reinforcement and matrix. Their mechanical and physical properties were measured according to composite standards. The compounding mechanism and chemical reactions were properly performed for each sample and crosslinking between all materials was characterized. The theoretical density of the samples was determined using the rule of mixture. After conducting all experiments, a composite sample with 27.645 MPa of tensile strength, 22.061 MPa of tear strength, an increase in hardness, an average actual density of 1.1195 g/cm3 and an increase in abrasion resistance capability was selected. This study demonstrates the potential for recycling HDPE scraps and waste glass powder into a composite material with desirable mechanical and physical properties for use in the production of pipes. The experimental results indicate that the waste HDPE and glass powder can be effectively processed and utilized as a cost-effective and sustainable alternative to virgin materials for the production of composite materials. The use of waste materials in this manner can not only reduce the environmental impact of industrial waste but also create new opportunities for the recycling and repurposing of waste materials. Furthermore, the resulting composite material can offer improved mechanical properties such as tensile strength, tear strength and abrasion resistance, compared to traditional materials. This study provides valuable insights into the development of sustainable composite materials and offers a promising avenue for future research on the recycling and reuse of waste materials.
Experimental Analysis for the Performance Assessment and Characteristics of Enhanced Magnesium Composites Reinforced with Nano-Sized Silicon Carbide Developed Using Powder Metallurgy Nadeem Faisal, Dheeraj Kumar, Amit Kumar, Alok Kumar Ansu, Abhishek Sharma, Abhishek Kumar Jain, Meshel Q. Alkahtani, T. M. Yunus Khan, Naif Almakayeel ACS Omega, 2024 Magnesium, which is lightweight and abundant by nature, was widely used in the 19th century to make parts for automobiles and airplanes. Due to their superior strength-to-weight ratios, magnesium alloys were favored for engineering applications over unadulterated magnesium. These alloys result from the combination of magnesium with various metals, including aluminum (Al), titanium (Ti), zinc (Zn), manganese (Mn), calcium (Ca), lithium (Li), and zirconium (Zr). In this study, an alloy of magnesium was created using the powder metallurgy (PM) technique, and its optimal performance was determined through the Taguchi-Gray (TG) analysis method. To enhance the alloy's mechanical properties, diverse weight fractions of silicon carbide (SiC) were introduced. The study primarily focused on the Mg-Zn-Cu-Mn alloy, achieving the optimal composition of Mg-3Zn-1Cu-0.7Mn (ZC-31). Subsequently, composites of ZC-31/SiC were produced via PM and the hot extrusion (HE) process, followed by the assessment of the mechanical properties under various strain rates. The use of silicon carbide (SiC) resulted in enhanced composite densities as a consequence of the increased density exhibited by SiC particles. In addition, the high-energy postsintering approach resulted in a decrease in porosity levels. By integrating silicon carbide (SiC) to boost the microhardness, as well as the ultimate compressive and tensile strength of the composite material, we can observe significant improvements in these mechanical properties. The experimental findings also demonstrated that an augmentation in the weight fraction of SiC and the strain rate led to enhanced ductility and a shift toward a more transcrystalline fracture behavior inside the composite material.
Thermal Behaviour of Epoxy Composites Filled with Micro-sized LD Slag Particulates Priyanklohiya, Alka Agrawal, Alok Agrawal, Abhishek Jain, A Erdoan, et al. Jordan Journal of Mechanical and Industrial Engineering, 2023 This article reports an investigation of the thermal behaviour of the epoxy/LD-slag composites prepared by hand layup method at varied loading of filler from 0 wt.% to 40 wt.%.The main aim of the work is to establish hazardous industrial waste as a filler material for the development of polymer composites.The thermal conductivity of neat epoxy is 0.15 W/m-K and the same improves to 0.292 W/m-K with the addition of 40 wt.% LD-slag.The addition of LD slag appreciably improves the epoxy matrix's thermal stability by increasing its degradation temperature at different levels along with the enhancement in the char residue.The maximum glass transition temperature of 74.74 o C is attained for a filler loading of 20 wt.%, whereas, a negligible reduction is observed at higher filler loading.Further, the material's specific heat capacity also progressed with the inclusion of LD slag and reached 1.115 kJ/kg-o C showing an increment of 57.7 over the neat epoxy resin for a combination of epoxy/40 wt.% LD slag composite.The coefficient of thermal expansion gainfully declines with filler loading and decreases by 14.18 % for 40 wt.% of LD slag.The minimum coefficient of thermal expansion value registered is 59.3 10 -6 / o C.
