Embedded Automobile Engine Locking System, Using GSM Technology

This paper deals with the design & development of an embedded system, which is being used to prevent /control the theft of a vehicle. The developed instrument is an embedded system based on GSM technology. The instrument is installed in the engine of the vehicle. An interfacing GSM modem is also connected to the microcontroller to send the message to the owner’s mobile. The main objective of this instrument is to protect the vehicle from any unauthorized access, through entering a protected password and intimate the status of the same vehicle to the authorize person (owner) using Global System for Mobile (GSM) communication technology. This system deals with the concept of network security. The main concept in this design is introducing the mobile communications into the embedded system. The entire designed unit is on a single board

Post-Covid Challenges and Opportunities for Higher Education

All over the world, the Covid-19 pandemic has had a big impact on the higher education sector. It has also put a lot of pressure on the Indian system of higher education. As a result, all academic institutions and colleges now teach their students through online platforms, thus forcing the higher education sector of the country to move its base online. The present crisis should be used as an opportunity to devise new ways to improve education that everyone can use and understand. Many new types of learning, new ideas, and recent trends have resulted from the pandemic. As we move forward, the same may happen

A Simple Scheme for Visual Cryptography

Here an algorithm is proposed to implement (2, 2) secret sharing problem which reduces the size (resolution) of the generated shares. Instead of considering one pixel at a time to generate the share, two consecutive pixels of the original image are considered row wise. Finally a pixel share having six pixels is generated for the considered two consecutive pixels. Thus we get six pixels instead of eight pixels in the shares corresponding to two pixels in the original image. As a result two pixels (8-6 = 2) in the share are reduced corresponding to two pixels of original image

Endophytes: A Treasure House of Bioactive Compounds of Medicinal Importance

Endophytes are an endosymbiotic group of microorganisms that colonize in plants and microbes that can be readily isolated from any microbial or plant growth medium. They act as reservoirs of novel bioactive secondary metabolites, such as alkaloids, phenolic acids, quinones, steroids, saponins, tannins, and terpenoids that serve as a potential candidate for antimicrobial, anti-insect, anticancer and many more properties. While plant sources are being extensively explored for new chemical entities for therapeutic purposes, endophytic microbes also constitute an important source for drug discovery. This review aims to comprehend the contribution and uses of endophytes as an impending source of drugs against various forms of diseases and other possible medicinal use
