Abstract: In the not-too-distant future, schools will convert from using the approach that is now being used to utilising an attendance system that is based on facial recognition; this technology may even wind up replacing biometric attendance systems. The purpose of this investigation is to come up with a novel approach to recording attendance that takes use of cv2 technology. Facebook also makes use of technology that can recognise faces, as can be shown by the fact that, as soon as you upload photos that you've previously tagged, it assigns names to the persons seen in those photos automatically. This demonstrates that facial recognition is used by Facebook. The software first searches the database for faces that contain distinguishing features, and then it encodes those features into a pattern image using those features......

Abstract: Database indexing is a vital activity to improve query performance, as indexes are the most commonly used technique to speed up query response time. Data inserts and updates take longer if the right columns are selected, which increases disk consumption and increases inserting and updating time. Therefore, it is important to optimize the performance of a NoSQL database using index selection. The code must be chosen according to the workload to ensure the efficient operation of the database. To manage the workload and index configuration selection, reinforcement.....

Abstract: The quantity of study on how environmental design and sustainability might affect 's habits, wellness, and well-being is significant and growing. Professionals in sustainable building research have long recognized how challenging it is to communicate their findings in a manner that users will understand and use. Urban space is a topic that receives a lot of attention in this study (parks, plazas, and streets). This study examines how the research and its technique interpretations are used by landscape architects who have attained professional reputation for their designs of urban open space The recommendations from this study, which might be made utilizing methods and data from the field of environmental design research, could be helpful to professionals to improve humans wellbeing. This study will assist students in performing, understanding, and applying their own direct evidence in their projects. Impacts of sustainable engineering research on suggestions and current situation..

Abstract: Vertical curve is designed in India based on the Indian Roads Congress (IRC): SP-23 -1993, AASHTO, UK and other Guide lines. Generally parabolic curve is used for the determination of elevation of summit curve and valley curve. When speed of vehicle is more than 200 even 400 kmph for innovative transport system like Hyperloop one, vertical curve could be designed with transition curve on either side of conventional vertical curve to avoid jerk due to such high speed with sudden changes in grade.This paper presents a guideline for design of vertical curve using transition similar to horizontal alignment and discus design methodology, benefit of user/ passenger while travelling on road.

Abstract: Development of an application where the general public can report illegal activities of drug trafficking anonymously and fearlessly. The importance of seizing illegal drugs cannot be overstated. It is essential for governments to take measures to reduce the supply of drugs on the streets and to protect the public from the harm associated with the use and distribution of drugs. Seizing illegal drugs can help to reduce the number of people who are exposed to the dangers associated with drug use, as well as to reduce the amount of drug-related crime[1] (Dhingra, Mobile application development using flutter , 2021). Additionally, seizing illegal drugs helps to send a message to potential drug traffickers and dealers that their activities will not be tolerated. The purpose of this research......
