With the rise in problems mainly ecological as well as energy crises that are intensifying today, the concept of green has become essential concerning sustainable development. The hospital building consumes much more energy and generates more waste, as compared to the other types of buildings. The climate change, contamination of chemicals, and use of unsustainable resources are all making health worse day by day over the world. The health sectors are themselves causing these problems on a broad scale. So, hospitals, health sectors must be green, there must be proper management of resources, waste etc., which means that it must have a minimum negative impact on the environment. The term Green Hospital has evolved as a way of addressing environmental issues, overcoming them and meeting society’s need. In India, Green Rating for Integrated Habitat Assessment (GRIHA) is one of the tools that provides green building certification to hospital buildings also. This paper aims at analyzing and investigating a hospital building (Trauma centre), Jawaharlal Nehru Medical College, Aligarh, based on major criteria of the GRIHA variant for existing buildings. This hospital building had been provisionally-rated by GRIHA in the year 2016 as 3 stars. This paper includes the analysis of building based on various calculations and in depth study of how this 3 star rating was provisionally achieved. This paper involves two main calculations, one regarding peak heat gain and the other is EPI.

CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a process of identifying whether user is human or robot. It is very important to know the user end because security can be breach. There are different CAPTCHA problems accessible like twisted string, image recognition, math and gaming CAPTCHA. Game based problem is intuitive and profoundly got as contrast with the other CAPTCHA. In this sort of CAPTCHA client needs to tackle an AI problem either by drag and drop technique or click based, contingent upon the game. The paper is expected to audit different carried out CAPTCHA and analyze their shortcoming and security boundaries. A large number of the CAPTCHAs are based on click based strategies where client needs to recognize the photos according to its appearance and snap in like manner. However, this sort of CAPTCHA can be mediated by image processing like object classifier. Dragging an item to the objective region is a successful way however it must be performed or tackled by a scholarly problem. On the off chance that dragging an item to the objective region by object acknowledgment, framework might get broken by relay attacks. Keywords: CAPTCHA, Gaming CAPTCHA, Picture Recognition, Web Security, Image Processing, Relay Attacks.

School is not only a building or an assembly of students and teachers, but also can be defined as a space for children to grow and shape their thoughts. Children spend almost half their working hours of the day at school. The lessons and values learned here at school affect the perception of students in their lives. Surroundings of a person leave a great impact on him. Hence, schools need to be sustainable for better growth of students as well as the environment. On a national level, the GRIHA-PRAKRITI rating system is currently working on this concept. This paper includes a detailed analysis and assessment of Senior Secondary School, Aligarh Muslim University at Aligarh, India, based on seven major criteria under the GRIHA-PRAKRITI rating system by using both qualitative as well as quantitative research methods. All 15 criteria are not analyzed in detail. So, the rating of the building has been calculated out of 25 points. The points came out to be 14 out of 25 and the 2-star rating is achieved. This school building was established in 1987 but still, it came out as a green building. The incorporation of only passive design strategies and creativity can contribute to a green building, hence saving resources and the environment as well.
