Portable Geo Specific Water Filtration Bottle

Students of Indian Institute of Technology Madras Ramesh Kumar and his team member Anupam Chandra won the award appreciation for developing a prototype of Portable Geo Specific Water Filtration Bottle. He carried his project work under guidance of Prof. T. Pradeep.

In all natural calamities, those who get most affected are the poor and affordable solutions are essential for alleviating their sufferings. In regions, such as West-Bengal and Assam where flood water can also contain regional contaminants such as arsenic, rapid removal of particulates, microbial, chemical and regional contaminate such as arsenic and fluoride require a combination of technologies to be effective at acceptable flow rates. A personal water purifier to deliver one liter of clean water from arsenic contaminated water requires materials with enhanced removal kinetics and high adsorption capacity so that filter is effective. This is currently possible only with advanced nano-materials in conjunction with other technologies such as nanofiltration, reverse osmosis, etc. Here it demonstrates an affordable purifier involving multiple technologies for microbially, chemically and heavy metal safe drinking water. In this purifier bottle, feed water passes through four stages of filtration, 1) reusable pre-filter, which removes all particulate matter, 2) microfiltration / ultrafiltration hollow fiber membrane cartridge, which removes all microbial and viral contaminants, 3)geo-specific filtration unit, which removes geo-specific contaminant such as arsenic, fluoride and pesticides, 4)silver nanoparticles decorated activated coconut charcoal, which provides antimicrobial and organic contaminant removal capacity to the water purifier bottle. To develop pressure required in feed water container vessel for microfiltration or ultrafiltration, a hand operable bellow pump is added to the unit. Cheap and indigenously developed filtration membranes make this water purifying device affordable for mass distribution to the affected population of a natural disaster.

A Mechanism for Toilet Seat Sanitation

Students of Indian Institute of Technology, Madras Arvind Pujari and his team members Shashwat Jain, D V S S S Kushal Kumar Reddy, Subham Kumar Sahana and Tanay Garg won the GYTI award appreciation for developing a A Mechanism for Toilet Seat Sanitation.

A simple, purely mechanical device is developed to ensure the sanitation and cleaning of the toilet seat by the push of a foot pedal which can be implemented as an add-on to the existing toilet structure. The mechanism consists of three parts. a) A Lifting Mechanism: A foot pedal lifts the seat, as seen in dustbin lids. b) A Spraying Mechanism: When the seat reaches its apex position, a nozzle is automatically pressed, spraying a sanitizing liquid onto the seat. There are four such nozzles, thus ensuring that the entire seat is sterilized. c) A Wiping Mechanism: The wiper is a rod attached with a removable sponge, located at the back end of the seat, so that it does not encumber the user. When the foot pedal is pressed, the seat is lifted and the wiper is lifted along with the seat until it reaches the front edge, thus cleaning the seat of any dirt or water left by the previous user. Then the spray heads attached to the lid of the seats are pressed and spray a sanitizing liquid on the seat. The spray is uniformly spread and wiped across the seat, by the wiper, thus completely sterilizing it. There are many advantages of this mechanism over currently implemented methods (such as disposable seat covers, sanitary wipes, sanitary sprays and UV light). Thus, this device provides a low cost (the device will cost less that 1000 to manufacture and set up), user friendly, touch free and electricity free method of sanitizing and cleaning the toilet seat by the simple push of a foot pedal.

Grid Interactive Solar PV Based Water Pumping Using BLDC Motor Drive

Rajan Kumar, student of Indian Institute of Technology, Delhi received the Gandhian Young Technological Innovation Award-2017 appreciation for developing a prototype of a Grid Interactive Solar PV Based Water Pumping Using BLDC Motor Drive under the guidance of Prof. Bhim Singh.

Being a grid-isolated or standalone system, the existing brushless DC (BLDC) motor driven water pumps fed by a solar photovoltaic (SPV) array, rely only on solar PV energy. Due to its intermittency, the solar PV generation exhibits its major drawback which results in an unreliable water pumping systems. In the course of bad climatic condition, water pumping is severely interrupted, and the system is underutilized as the pump is not operated at its full capacity. Moreover, an unavailability of sunlight (at night) leads to shutdown of an entire water pumping system. This innovation proposes a bidirectional power flow control of a grid interactive SPV fed water pumping system. A BLDC motor-drive is used to run a water pump. This system and control enable a consumer to operate the water pump at its full capacity for 24-hours regardless of the climatic condition and to feed a single-phase utility grid when the water pumping is not required. The full utilization of SPV array and motor-pump is made possible in addition to an enhanced reliability of the pumping system. Using a single-phase voltage source converter (VSC), a unit vector template (UVT) generation technique accomplishes a bidirectional power flow control between the grid and the DC bus of voltage source inverter (VSI) which feeds a BLDC motor. The maximum power point (MPP) operation of SPV array, and power quality standards such as power factor and total harmonic distortion (THD) of grid are met by this system.

Paper-based device for rapid detection of Dengue

Sanjay Kumar and his team member Pulak Bhushan won the award appreciation for developing a Paper-based device for rapid detection of Dengue. He carried his project work under the guidance of Prof. Shantanu Bhattacharya, Indian Institute of Technology, Kanpur.

Dengue virus is diagnosed using conventional techniques like PCR (polymerase chain reaction) and ELISA (enzyme-linked immunosorbent assay), and even though these methods are highly accurate they need a highly clean lab and expert people to perform these tests. They are also highly expensive and time consuming. The previously developed devices have one major limitation from the commercial point of view. They utilize saliva or serum as their samples. Even though they are an important source of biomarkers and have less interference, they require pre-processing before they can be used. The pre-processing can only be done in a laboratory rendering it useless for developing commercially available lateral flow test strips. Several rapid diagnostic devices are available in the market for detection of dengue. The devices that detect NS1 are only capable of doing so after 3-4 days, since that is when the concentration of Ns1 increases to a considerable amount. Whereas, the devices that can detect IgM and IgG, suffer from the problem that these antibodies are produced in the body only after 4 days and 7 days respectively (primary infection), hence rendering them useless for early detection purposes. The primary objectives of this project are as follows: Development of a device which can detect dengue NS1 in the first 1-2 days itself, when the concentration of NS1 is considerably low. This shall make the device capable of providing an early diagnosis which will further aid the doctors in treating the patients in an effective way. Using whole blood as the sample, eliminating the need of pre-processing which requires external equipment and expertise.

OCR++: A Robust Framework For Information Extraction From Scholarly Articles

Students of the Indian Institute of Technology, Kharagpur were received the Gandhian Young Technological Innovation Award-2017 for developing a website of OCR++: A Robust Framework For Information Extraction From Scholarly Articles.

Mayank Singh Including his team members Barnopriyo Barua, Priyank Palod, Manvi Garg, Sidhartha Satapathy, Samuel Bushi, Kumar Ayush, Krishna Sai Rohith, Tulasi Gamidi developed this website under guidence of Dr. Pawan Goyal and Dr. Animesh Mukherjee.

This project proposes OCR++, an open-source framework designed for a variety of information extraction tasks from scholarly articles including metadata (title, author names, affiliation and email), structure (section headings and body text, table and figure headings, URLs and footnotes) and bibliography (citation instances and references). A diverse set of scientific articles written in English to understand generic writing patterns and formulate rules to develop this hybrid framework is analysed. Extensive evaluations show that the proposed framework outperforms the existing state-of-the-art tools by a large margin in structural information extraction along with improved performance in metadata and bibliography extraction tasks, both in terms of accuracy (50% improvement) and processing time (52% improvement). A user experience study conducted with the help of 30 researchers reveals that the researchers found it to be very helpful.

Fish-Inspired Propulsion System for Remotely Operated Surface Ships and Underwater Vehicles

Mannam Naga Praveen Babu won the award for the research project ‘Fish-Inspired Propulsion System for Remotely Operated Surface Ships and Underwater Vehicles’. He carried his research work under the guidance of Prof. Krishnankutty P. Department of Naval Engineering, Indian Institute of Technology Madras, Chennai.

The Autonomous Marine Vehicles (AMVs) are much in use for exploring subsea natural resources, monitoring marine pollution, performing hydrographic surveys, etc. Energy for AMV operations are taken from battery cells provided inside the AMV. The energy consumption can be reduced by providing the AMVs with a propulsion system which is more efficient than the conventional screw type thrusters. Recent advances in planetary sciences shows that NASA is trying to explore liquid atmospheres such as methane lakes, icy crust atmospheres in Jupiter's largest moon Europa and Titan planets with the help of robotic eel fish and underwater submarines. The use of marine vehicles on earth ocean's world exploration advances into planetary atmospheres. Compared to conventional marine vehicles, bio-inspired swimming vehicles have shown higher performance in comparison to screw propellers. This performance results in efficient cruising, maneuverability (turning and stopping ability), noiseless motion and eco-friendly. These are defined as fish-like bio-inspired vehicles which propel through undulation or oscillation motion of the fish body or its fins. Flapping foil propulsion are more efficient (80%) than the conventional screw propulsion system (60%). Use of flapping foils also disturbs the water less compared to screw propellers, thus making it more environment friendly and create less noise. With these perspectives under consideration, the present research reports the studies carried out on a remotely operated surface ship model and underwater vehicle fitted with a fin at the aft end, resembling caudal fin of a thunniform fish. The aft (tail) fin has freedom to oscillate in the horizontal plane about the longitudinal axis. Self-propulsion tests are carried out for determining the thrust performance of marine vehicles

Never Ending Learning Of Sound

Ankit Shah including his team members Rohan Badlani, Benjamin Elizalde, Anurag Kumar National Institute of Technology, Surathkal received the Gandhian Young Technological Innovation Award-2017 for developing an application on Never Ending Learning Of Sound. He carried his project under guidance of Prof. Bhiksha Raj.

Sound recognition is critical to the development of artificial intelligence. However, sound recognition remains an arcane task for computers, given the incomplete understanding of how humans are able to recognize sound and understand its meaning naturally. Never Ending Learning of Sound (NELS) is a system that will continuously learn about sounds through direct supervision or automatically, and expand its vocabulary of sounds through analysis of audio and multimedia recordings and thei r corresponding metadata. It will eventually present a comprehensive repository of sounds – an invaluable resource in many fields – ranging from automatic video content analysis to audio forensics. India is on its path to a digital transformation, and a semantic understanding of sounds from NELS will help create smarter cities, robotics, automated surveillance systems and will also redefine tangible experiences for approximately 60 million deaf people in India. NELS will identify known sounds and detect the occurrence of new. Then, learn to recognize new sounds and associate their semantics and metadata to increase its vocabulary. It will also learn hierarchies in the structure of sounds, learn physical and common-sense structural and temporal relationships between sounds, and associations between sounds, their meaning and semantics and categories. NELS system will provide the largest and most up-to-date available repository of sounds in the world.

Blood Quality Assessment using Digital Holographic Microscopy

Mandeep Singh including his team member Azhar Muneer won the award for the research project Blood Quality Assessment using Digital Holographic Microscopy. He carried his research work under the guidance of Dr. Kedar Khare and Dr. Sarita Ahlawat Indian Institute of Technology, Delhi.

The stored blood in blood banks is used regularly in surgical procedures or transfusions. Blood quality assessment is therefore an important routine task. Current blood quality assessment protocols involve a number of chemical assays or impedance measurements making the process cumbersome and difficult to standardize. In recent years IIT Delhi has developed and patented a superior DHM technology for accurate high resolution 3D imaging of biological cells for blood cell classification and quality assessment. DHM operates on the principle of interference of light and can provide accurate information regarding minute refractive index changes in the cells that are ultimately related to cellular changes in response to ageing, physical cell damage or infections. Using the novel 3D imaging capability of this prototype system has indicated that fresh and old red blood cells have clearly distinguishable morphological features.

Mandeep SinghThe specialty of the DHM technology is that the usual wet-lab processing of cells prior to their analysis can be minimized thus significantly reducing recurring costs for chemical reagents. With a more systematic effort in this direction the aim is to develop a methodology for blood cell classification and quality testing that can benefit large number of hospitals, blood banks and pathology labs across India and beyond. The work is expected to lead to an early application of an indigenously developed microscopy technology with superior imaging performance.

Enhancement of Distribution System Performance using High Voltage Alternating Current (HVAC) Boost Converter and Fuzzy Controller

Anusha Vadde Student of the M. S. Ramaiah University of Applied Sciences, Bengaluru received the Gandhian Young Technological Innovation Award-2017 for developing a prototype Enhancement of Distribution System Performance using High Voltage Alternating Current (HVAC) Boost Converter and Fuzzy Controller. She carried her project under guidance of  V. S. N. Sitaramgupta V.

Power quality is one of the key factor in electrical systems and is taken into consideration to meet the demands of the customer. Voltage dips, momentary interruptions, harmonics and transient surges affect the reliability and quality of the power supply. The reliability and cost of any electrical system depends on the quality of the supplied power and consumed by the system. High Voltage Distribution System (HVDS) is one of the methods used to improve the quality and reliability of the distribution system through a reduction in losses, voltage fluctuations and power consumption. In HVDS, power is transmitted from the distribution station to consumer premises through the booster transformers and voltage regulators. Inrush currents or magnetizing currents and heating of insulation have been observed in transformers due to non-linear loads. As a result, the current drawn by the system is high. To overcome these effects, a step-up power converter with fuzzy controller has been designed. In this research work, High Voltage Alternating Current (HVAC) Boost Converter with fuzzy controller has been proposed for a costeffective solution to reduce distribution losses. Simulation studies have been carried out for verifying the utilities of the proposed design. The performance of the designed fuzzy logic controller is compared with that of the existing booster transformer scheme by using the simulations. It has been found that the efficiency is improved by 4%, and power losses are reduced by 1.4% to maintain the voltage fluctuations within the acceptable levels. The proposed controller in the case study of old city area in Hyderabad has been shown that revenue savings are increased by 12%.
