2nd prize: Image, Speech Recognition and Speech Synthesis for people with hearing and speaking disabilities
Project Hope is an Image, Speech Recognition and Speech Synthesis System. It aims to aid people with hearing and speaking difficulties. This system uses a webcam to convert signs into text. It has a text-to-speech conversion utility. When the other person speaks, the system will convert it into text which the person with hearing and speaking difficulty can read. Presently the system only supports English. The device is lightweight and wearable.

‘More from Less for Many’ Innovations
1st prize: LPG Based Refrigerator
LPG based refrigeration works on the principle of expansion of LPG, which leads to cooling. This cooling effect can be used for non-consumptive refri-geration purposes. The GYTI Awards Committee received prototypes based on this concept from two teams.
Team 1:
The team from Laljibhai Chaturbhai Institute of Technology made a prototype in which the refrigerator temperature reached -5 ºC at an ambient temperature of 12 ºC.

Team 2:
The team from LDRP ITR utilised this principle to develop a heat exchanger comprising a network of pipes through which LPG gas can pass, covered by thin and closely spaced fins. The additional fins help in effective and faster cooling. The insulating material helps in storing the cooling effect for a longer time.

Incense Stick Maker (Appreciation)
The low cost agarbatti maker consists of a roller mechanism in which the dough is fed. The agarbatti paste is flattened using calendar rolling systems. The flat paste is then cut into strips of the required width using a cutting roller, which is later wrapped around the bamboo stick with a wooden roller.
The final assembly consists of rollers made of wood, rubber conveyor belts and steel pipes. A person operating this machine may be able to roll about 6000 sticks a day.

Domestic Refrigerator with Water Heater (Appreciation)
This is a dual function domestic refrigerator. The waste of the compressor heat is used to warm water, through a heat exchanger and in the process of heat removal, the compressor’s life is extended, increasing the efficiency and reducing the power consumption. The lukewarm water thus generated, can be used for household chores.

Automobile Air Conditioning System using Engine Exhaust Heat (Appreciation)
A car AC consumes about one-tenth of the total fuel. This air conditioning system devised by Harish Tiwari and Prof Parishwad is able to run using the waste heat from the automobile exhaust pipe, saving a significant amount of fuel.
The air-conditioner uses an absorption refrigeration system powered by exhaust heat. The prototype developed in the laboratory has a power of 1kW. The absorbers use a double pipe as a heat exchanger to enhance heat transfer and reduce the heating and cooling time. The system has been designed for long distance truck rides under extreme weather conditions.

‘Technological Edge’ Innovations- Award Winners’
1st Prize: Smart Grid Forecasting Technique
Increasing renewable energy generation will gradually lead to creation of a decentralised electricity grid, posing greater challenges in grid stabilisation. Stabilising such a decentralised grid requires integrating the ability to forecast grid parameters and respond appropriately within the grid.
VSK Murthy has developed km-technology (km-tech) that
uses golden search interpolation techniques, Fibonacci functions, robust regression algorithms and novel advanced neural networks to give accurate forecast of tariffs, effective load, wind energy and grid frequency.
V S K Murthy Balijepalli, IIT Bombay
2nd Prize: Tiles Measurement and Grade Classifying Equipment
This equipment uses an embedded system to classify different grades and thickness by means of digital image processing and ultrasonic waves. The ceramic tile industry is almost completely automated except for the last step of visual inspection for the classification of tiles into different grades. In this system, images of tiles are captured, digitised and an algorithm is used to compare them against a standard image. Accordingly, the tiles are classified.

3rd Prize: Ultra Sensitive, Low Cost Handheld Explosive Detector System
This handheld device can detect the vapours of TNT & RDX using micro-cantilever based sensors. This 9V battery operated device costs about 5% of the existing instruments. The user-friendly portable system has an alarm with LCD display measuring 6 cm x 12 cm.
A concentration of 10 parts per trillion can be detected within a few seconds by this system.

A Tsunami Warning System using Ionospheric Measurements (Appreciation)
A low cost tsunami forecasting system has been developed by students using TEC data from Pratham (a satellite developed by IIT Bombay). The use of in-house satellite reduces the cost of the system significantly. The TEC data is generated using ten ground stations in India and one in France. The algorithm reconstructs the distribution of electron density across various layers of the ionosphere with more than 85% accuracy.

Design, Synthesis & Evaluation of Novel Steroidal Aromatase Inhibitors in Breast Cancer (Appreciation)
Dr Sabale has developed a drug formulation using carbonitriles that inhibits breast cancer causing agents . Inhibition of aromatase, a cytochrome P-450 enzyme responsible for biosynthesis of oestrogens, is an effective approach for the prevention and treatment of oestrogen-dependent breast cancer. A carbonitrile group in ring-D is introduced to observe its impact on the aromatase inhibiting activity of the molecule. The novel compound has been synthesized and evaluated for its potential as aromatase inhibitor using human placental microsomal preparation as the enzyme source and another substrate.
