 Abstract

Developing a cryptography model that can translate legible writing from common language and converse is the aim of this research. For SoC level FPGA, the AES 128-bit symmetric cryptography technique is used to avoid malware in both hardware and software. The ideal AES design with an enhanced security scheme is also described in this study. The suggested model enables pipelined reusing of the same hardware. Furthermore, suggests expanding the use of dynamic key extraction in cryptosystems to increase randomness through the addition of outer layer security. A completely automated process for creating keys framework utilizing digital biometrics is utilized to produce a 256-bit key with enhanced randomness for 32 From the provided digital biometric, pixels are randomly selected, and the values of all the selected pixels are concatenated at random to generate a 256- bit encryption key.

 Abstract

To fulfill the demands of globalization in the construction of buildings and infrastructure, India has recently made a significant effort in constructing the infrastructure, including expressways, power projects, and industrial structures, among other things. Concrete and cement are commonly utilized in construction and building techniques across the globe. It is necessary to switch to green concrete from Ordinary Portland Cement (OPC), since OPC uses more energy and harms the environment. In this study fly ash is used as an alternate to OPC, as fly ash has a high silicate and alumina content, it combines with an alkaline solution to form an alumino-silicate gel, which bonds the aggregate and results in high-grade concrete. The concrete mix proportioning used is M30 GRADE and activation of geo polymer concrete is done using alkaline activators such as sodium hydroxide and sodium silicate solutions, finally checking the mechanical strength properties of GPC in comparison with conventional concrete

 Abstract

This study presents a detailed analysis of retractable roofs. The retractable roof is a versatile architectural feature designed to provide flexible shelter and climate control for various structures, such as stadiums, arenas, and outdoor spaces. This innovative technology allows for the seamless transition between open-air and covered environments, offering protection from adverse weather conditions while maintaining an open-air experience when desired. It aims at enhancing the overall spectator experience and ensuring uninterrupted gameplay, regardless of adverse weather conditions. This innovative system involves mechanized panels and sections that can be opened or closed. The length of retractable roofs increases with the demand for more flexible and light construction, and such requirements mark retractable roof structures more sensitive to wind actions. The project outlines the potential impact of this innovative solution on the sports industry and multipurpose events.

 Abstract

Using lignin extract to mend craters has shown favorable results in addressing the challenges posed by pavement distresses on roads and highways. Traditional methods for repairing craters involve resource-intensive hot asphalt mixtures, resulting in temporary fixes. This project introduces an innovative approach using additive extrusion technology and lignin extracted from coconut coir for more efficient, cost-effective, and durable pavement repairs. By blending lignin with bitumen and incorporating urea formaldehyde polymer, this method helps in utilizing the full benefits of a pavement and offers a sustainable alternative to traditional materials. This eco-friendly solution not only strengthens road surfaces but also contributes to greener road maintenance practices, ensuring safer and increases the durability of pavements.

 Abstract

The focus of present researchers shifted towards utilizing local available alternative materials with binding properties in concrete as a cement replacement. Utilization of agricultural waste with pozzolanic properties in concrete will further aid for sustainability. Thus, the present study is initiated evaluate the mechanical of pervious concrete with sugarcane ash replacing cement. Porous concrete is gap graded concrete mix with minimum or no fine and which allow water to percolate in to the earth beneath the pavement. Porous concrete being used as structural layer in the pavement, the concrete mix shall require minimum structural strength, as well as the permeability properties. M20 concrete mix design process is adopted in the present study, with an assumption that the cement mortar just coats the aggregate and does not completely fill any voids. The dried sugar cane waste is incinerated at 2500 C to get the sugarcane ash, which is further sieved through 150 microns sieve, and the passing fraction is used in mix as a partial replacement for cement. Concrete cubes with sugar cane ash replacing cement in ratios of 0 %, 0.5 %, 1 %, and 1.5% by weight were prepared to evaluate the 7 days, 14 days and 28 days compressive strength. The compressive strength (N/m2) obtained for 0.5% is 112, 191, 120, 1% is 205,210,218. and 1.5% is 280,292,302 for 7, 14 and 28 days respectively.

 Abstract

Curing is said to be the method of maintaining minimum moisture content after construction to develop the desirable properties. In many situation curing is not possible so, to overcome those situation we are using chemicals to attain the process of curing. The chemicals like Poly-vinyl alcohol (PVA)and Poly ethylene glycol (PEG-400) contribute on cement by giving good Strength and hydration rate. This self curing agents gave better compressive strength and split tensile strength.

 Abstract

The process known as liquefaction, which occurs when there is an excess of "pore water pressure" and a drop in the frictional resistance of the soil after an earthquake, is what causes the solid ground to change into a liquid condition. Sands that are loose or somewhat wet and have poor drainage, such clayey or silty sands, are susceptible to liquefaction. The standard penetration test (SPT) and the cone penetration test (CPT), which are favoured to evaluate the liquefaction potential of soil, are examples of in-situ tests that are the foundation of common liquefaction evaluation techniques. Rearranging the soil particles into tighter arrangements increases density and is known as densification. Using the stone column strategy, soil stability is increased as part of the ground-up improvement process. To compress the soil and raise its density, drop a large weight onto the ground several times from a considerable height

 Abstract

This study is to analyze the compressive strength of concrete by partially replacing cement with Fly Ash and Ground Granulated Blast Furnace Slag (GGBS). The use of supplementary cementitious materials, such as Fly Ash and GGBS, in concrete production has gained significant attention due to its potential to enhance the sustainability and durability of concrete structures. This study is to work out the effect of mineral admixture GGBS and Fly ash in concrete of grade M-40 when it is added in & replaced for the fresh state and hardened state i.e. for workability and strength of concrete using OPC (43 grade). As mineral admixture GGBS and Fly ash have been added to OPC which varies from 20% and 40% at interval of 20% &40% by total weight of OPC, various range of addition and replacement of cement by GGBS and Fly Ash in the concrete. All mixes of concrete will examined for workability as slump test of fresh concrete. Hardened concrete is examined for Compressive strength for 7days,14days and 28 days. Slump will be analysed as compared to that of addition of GGBS & Fly ash.The research findings contribute to the understanding of the performance of concrete mixtures containing supplementary cementitious materials and offer practical recommendations for their utilization in construction. By addressing these objectives, this research endeavors to advance the knowledge and practice of sustainable concrete production and promote the responsible use of Fly Ash and GGBS in the construction industry.

 Abstract

In the present era design of any structural element would be a challenging task. Design of compression members being most challenging to decide the section is capable to withstand or bear the force applied on it. Hence design of Structural members are always designed based on number of trails and error method. While undertaking many trails, design calculations with their design checks proves a length and time consuming. Hence, in the present study efforts are put to build the stock of various design combinations of compression members by pre-assuming the sectional date and applying forces, moments on it. And suitable conclusion will be made at the end.
