Abstract: Our team is designing and developing the Upper Limb Exoskeleton Arm which will be fitting on the right hand. Our model is based on Mechatronics Domain. Though this system exist in the market, the model present in the market is bulky, expensive and more complex to use. The main challenge in front of our team is to build an arm which will be fully automated, light in weight and economical. We are planning to develop an arm which will be mainly focusing on the Indian market. The arm will be used by common workers in industries, handicapped people and also the doctor.....

Abstract: Waste Recycling Is Essential Economically And Environmentally. The Principal Purpose Of This Investigation Is To Analyze The Probability Of Utilizing Seashells (SS) And Their Effect As A Partial Alternative For Sand On The Characteristics Of Plain Concrete (PC) And Fiber-Reinforced Concrete (FRC). Six Percent (0%, 10%, 20%, 30%, 40%, And 50%) Of Seashells Were Used. The Proportion Of Steel Fiber (SF) And Polypropylene Fiber (PPF) Used In This Investigation Was 1% And 0.30% Of The Concrete Volume, Respectively. The Water/Cement (W/C) Proportion Was 0.65 For All Concrete Mixes. The Unit Weight And Slump Of Concrete Reduced With The Growth In The Substitute Ratio Of A Seashell For All Concrete Mixtures While The Absorption Ratio....

Abstract: Natural hazards pose a serious threat to urban infrastructure by a significant margin. They cause widespread damage and disruption to the community properties, like the destruction of houses, and road deformation, among others. Common hazards include earthquakes, hurricanes, floods, and other cataclysmic occurrences, which have proven their destructive power over structures and transportation networks. Some regions have been prone to earthquakes causing economic losses, environmental degradation, and loss of life (Maria & Elena, 2022). As the frequency.....

Abstract: Bendable concrete is an Engineered Cementitious Composite (ECC)that has high flexural strength and considerable tensile strength compared to conventional concrete. The CO2 emission is relatively less in ECC which contributes to reducing the global warming effects and promotes sustainable practices. Conventional concrete has a straining capacity of 0.1% and it is a brittle material. In contrast, bendable concrete is flexible and fosters elastic properties. Due to the absence of coarse aggregate,the self-weight of the concrete mortifies.Moreover,.....
