Abstract

This paper reports the response of the groundwater in the St Peter's Engineering College campus, Avadi, near Chennai, India. Artificial recharge of rainwater was done through roof top harvesting methods during 2004 to 2007. Based on a hydro geological survey of the campus, eleven bore well were sunk for augmenting water supply to the campus. The lithology of each bore well was also recorded. A percolation pond in 1 ha area on the south eastern side of the campus was dug to collect and store the rainwater harvested from rooftops of the campus buildings. The survey also assisted in the identification and location of about 70 number of recharge wells in the campus. Pumping test was conducted in well no:3 to assess the hydraulic conductivity and calculate other aquifer parameters during 2005. A three layer hydro geological model of the aquifer was applied in Visual Modflow ver 4.1 environment and the model fit was 84% between observed and predicted values (R² = 0.844). Significant increase in water level in the top aquifer during 2007 was recorded when compared to 2004. The flow profiles in the middle and deep aquifer showed responses, through changes in the direction of flow to the pumping wells (5, 6 in 2004 and 2, 3 in 2007). In 2007, with improved recharge, changes in the direction of groundwater flow and discharge of water from the aquifer in the southern part of the campus can be noticed. The flow directions in the three aquifer layers also indicated that the northern part of the study area serves as an effective recharge zone for the St Peter's Engineering College Campus. Rainwater harvesting and recharge studies form important part in groundwater restoration and management in intensely urbanized cities/townships.

Abstract

Objectives: This paper describes a system and method for security at the toll booth. The system uses an alternative payment method that allows the user to make the payment quickly avoiding delay and also uses a mobile application that allows the user to recharge the mobile wallet. Methods/Statistical Analysis: Every lane has been divided based on two categories: one lane for drivers who have sufficient balance in their wallet and the other lane for the other category. The other category includes the drivers not having balance in their wallet, payment through cash in case the individual does not have the application or, mobile malfunction. The transaction is performed through radio frequency communication. The lanes at the toll-booth are divided into two sub-lanes depending upon the amount of money present inside the wallet. Findings: The smart system comprises of a database of users that are saved and have register on their mobile application. In the event of any vehicle stolen, theft case or robbery this database can be helpful in identifying the culprit and the vehicle. The database is stored at the Regional Transport Office (RTO). Application/Improvements: The invention finds applications in entrance of school, college, university and offices, airport, railway parking and at sports stadium.

Abstract

Objectives: This paper describes a system for inspecting the pipelines used under sea water by robotic ultrasonic methods. The invention discusses the use of a series of robots inside the pipeline for the detection of defect using the ultrasonic testing. Methods/Statistical analysis: The underwater piping system is the best option for the transportation of oils and natural gases as this pipe ranges a large distance. But there is the possibility of defects such as crack, or corrosion on the wall of pipes. So in order to detect any defect on the interior surface of pipe, non-destructive testing methods are employed. As the pipeline is so long, it is impossible to go and check manually. So robots are deployed inside the pipe line for inspection. In some cases inspection of defects using a single robot is not accurate. Therefore in this present disclosure a series of the robots are deployed in the pipeline which moves to and fro motion to cover certain distance. The series of robots are placed at a specific distant to each other as there will be no collision between them. Findings: The deployed series of robots detect the defect by using the ultrasonic non-destructive testing. Ultrasonic inspection is the technology used to test the objects by directing the higher frequency sound waves onto the object to find defects on both surface and internal. This beam travels through the object with some loss, except when it is diverted and reflected by a discontinuity. The detection, location, and evaluation of discontinuities become possible as the velocity of sound into the object being tested is almost constant. Application/Improvements: The use of a series of robots in the underwear piping system enables easier and better detection of faults and blockages in the piping system.

Abstract

Objectives: This paper describes an intelligent garbage monitoring system. Garbage management is an essential and mandatory process due to increase in human population and the amount of waste being accumulated. Methods/Statistical Analysis: Garbage accumulation leads to unhealthy environment and enables spreading of infections and diseases. The present invention provides a monitoring system and further includes a system to control the littering of the garbage in the vicinity of the bin aiming for a healthy and safe environment. An intelligent garbage monitoring system will be installed in all the localities and allows the monitoring party, the municipal corporation to view and take action according to the status of the garbage bin in that locality. Findings: The intelligent garbage monitoring system further has a control feature that prevents the users from spreading the waste around the vicinity of the garbage bin. The system aims for a cleaner environment and promotes a healthy life, by reducing the number of diseases that spreads due to improper waste management. Application/Improvements: The smarter garbage monitoring system enables a cleaner, healthier safer and disease free environment.
