Abstract Analysis of water quality monitoring technique based on fluorescence and UV LED is discussed. Exposing water sample to ultraviolet light induce fluorescence for detecting human faecal contaminants. Fluorometry identifies human faecal contamination in open water bodies. Existing systems make use of manual methods and incandescent filament based sources combined with narrow-band interference filters. Such systems suffer from problems of stability, bulk,... Analysis of water quality monitoring technique based on fluorescence and UV LED is discussed. Exposing water sample to ultraviolet light induce fluorescence for detecting human faecal contaminants. Fluorometry identifies human faecal contamination in open water bodies. Existing systems make use of manual methods and incandescent filament based sources combined with narrow-band interference filters. Such systems suffer from problems of stability, bulk, cost and degradation with time. This paper review some techniques used for monitoring bacterial contaminants in water and also looked at the feasibility of developing a UV LED fluorescence based device capable of detecting organic contaminants in water.

Abstract End of life of Cathode Ray Tubes (CRT) based Televisions, Monitors etc., end up as Electronic waste and the disposal of CRT glass poses a major environmental threat, mainly due to the presence of significant Lead in the Funnel part of CRT to an extent of about 30%. The present study attempts to a Novel usage of the Funnel glass... End of life of Cathode Ray Tubes (CRT) based Televisions, Monitors etc., end up as Electronic waste and the disposal of CRT glass poses a major environmental threat, mainly due to the presence of significant Lead in the Funnel part of CRT to an extent of about 30%. The present study attempts to a Novel usage of the Funnel glass from CRTs obtained from E-Parisaraa Pvt. Ltd., India’s First Government authorized E-waste recycling facility, Bangalore, Karnataka, as an aggregate substitute in the concrete admixture for application in radiation protection areas. Various proportions of funnel glass of CRTs were experimented by preparing M20 grade standard concrete cubes with various curing schedules. The cubes were subjected to various load bearing standard compression tests and correlated with X-ray Radiation Protection. The study concludes that, up to 30% funnel glass substitution as aggregate in the concrete admixtures can be successfully used for radiation protection walls, dooms of nuclear facilities, besides can also be used for radioactive waste containment and disposal. Accordingly we can utilize this experimental work to construct building with these cement blocks which may control the different radiation rays which solves the hazardous waste disposal problems and it is a sustainable environmental protections.

With the objective to improve public security, where avoiding terrorist attacks is an insisting priority for all governments, and also to enhance population safety, and improve the field of vision based processing, a lot of techniques of moving objects detection and tracking have been developed. One of the major challenges is to process images in real time using onboard camera on a moving unmanned aerial vehicles (UAV).In this paper we will present a survey of existing methods for detecting and tracking moving objects, using unmanned aerial vehicles. Generally, in literature the proposed methods are based on two parts, motion estimation and object detection and tracking. Read More Read Less
