 Abstract

Wireless communication has become an essential aspect of our lives. We rely on technology in nearly every aspect of our daily lives, from mobile phones to GPS systems. Year after year, network generations have improved significantly. The transition from 0G, which began with two-way radios, to 4G, which we all use today, brought about significant improvements in our lives. Now we can effortlessly speak with our loved ones who live far away, play online games, exchange films, check emails from anyplace, and much more. The world has shrunk significantly in size. Furthermore, research is being conducted on network generation to make them faster and more dependable while costing less. This paper provides insight into all of the network generations we have been introduced to thus far, as well as a glimpse into future generations and the technologies being developed to support them. In this paper, we provide an overview of several Wi-Fi technologies, notably 5G, 6G, and 7G, as well as specific comparisons between them.

 Abstract

A metric used by businesses to determine how satisfied consumers are with the features, services, and/or products they provide is called customer satisfaction. A multiplex is a group of theatres with several screens housed under one roof. They are usually housed in a specially designed building. Sometimes a pre-existing venue is modified, dividing the larger auditoriums into smaller ones or adding additional auditoriums by building enlargement or extension. The largest of these complexes, often referred to as a megaplex, can house thousands of people. The increasingly common multiplexes found in retail centers provide movie goers a genuinely better film experience. It makes sense that a growing number of people are choosing shopping mall multiplexes for their movie-watching experiences because of their unparalleled convenience, extensive movie selection, cutting-edge technology, and many other benefits. Mall-based theatres combine safety, lots of parking, socializing opportunities, and special offers to cater to a wide range of client needs and tastes while also positively impacting the local economy.

 Abstract

The Carbon Robotics LaserWeeder represents a significant improvement in precise weed management for specialty crops at a large scale. This advanced tool uses modern cameras and technology to rapidly differentiate weeds from crops. No matter the weather or time of day, it uses a variety of strong lasers to specifically aim and remove weeds. The LaserWeeder provides a sustainable solution for modern farming by increasing crop yield and reducing farming costs, addressing the long-standing issue of weed management that has troubled farmers for centuries. Manual weeding, machines, and herbicides have influenced the techniques used for weed management. Nevertheless, every method has its own drawbacks. Despite their effectiveness, herbicides can have negative effects on crop health and lead to environmental concerns. There is a danger of damaging plants while using mechanical weeding, and it is still difficult and costly to hire manual workers. With the progress of agriculture, there is a growing urgency for creative solutions. Farmers around the globe encounter a complicated network of difficulties in terms of controlling weeds. As weeds compete with crops for resources, they can significantly reduce the overall productivity of agricultural systems. Additionally, the increase in herbicide-resistant weeds has led to a decrease in the efficiency of conventional chemical treatments. The issue is worsening due to a lack of skilled workers willing to engage in manual weeding. It is still a challenging task for farmers to balance productivity, cost-effectiveness, and environmental impacts.By introducing the Carbon Robotics LaserWeeder, a cutting-edge device designed to fight against weeds. This autonomous robot operates 24/7 with great accuracy, utilizing artificial intelligence, sophisticated cameras, and 30 powerful lasers. It is effective on over 100 different types of crops and can be used on all soil types, including certified organic fields. offers a more environment-friendly alternative

 Abstract

As the population is increasing day by day, the need and demand for fossil fuels also increases. But formation of fossil fuels take millions of years and the existing fossil fuels can exhaust in less than a decade. Hence, it is important to find a suitable compensation. Renewable source of energy is abundantly available in nature. Conventional energy sources can be more efficient and are inexhaustible. A solar cap is one such project wherein solar energy or sunlight can be used for various applications or purposes avoiding the use or non-renewable resources. Solar cap can be used to cool down the heat with the help of a fan incorporated into it. The fan has three levels low speed, medium speed and high speed. Each one us are dependent on technology and especially on mobile phones. Hence, a solar cap is useful in charging mobile phones with instant power supply generated with the help of the solar energy or sunlight. This is helpful even in remote areas as it requires only sunlight. Thus, solar cap is quite reliable and cost effective many people who are travel enthusiast, people who live in remote areas and also to people who usually are fascinated about trekking and climbing.

This study investigates the fabrication and mechanical properties of ramie flax fiber epoxy composites reinforced with nano TiO2 filler. Ramie flax fibers were incorporated into an epoxy matrix along with varying concentrations of nano TiO2 filler. The composites were fabricated using a hand lay-up technique followed by compression molding. Mechanical testing, including tensile, flexural, and impact tests, bio-degradable was conducted to evaluate the performance of the composites. Results indicate that the addition of nano TiO2 filler enhances the mechanical properties of the composites compared to those without filler. Furthermore, scanning electron microscopy (SEM) analysis was employed to examine the morphology and interfacial bonding of the composites. Overall, this research demonstrates the potential of utilizing ramie flax fiber epoxy composites with nano TiO2 filler for various structural applications, offering improved mechanical performance and sustainability.
