Design and Development of Intelligent and Robust Grid Integrated Solar PV System with Improved Power Quality for Roof Top Applications Especially For Abnormal Indian Distribution Feeder

Students of Indian Institute of Technology Delhi, Amresh Kumar Singh, Ikhlaq Hussain won the award for research work of Design and Development of Intelligent and Robust Grid Integrated Solar PV System with Improved Power Quality for Roof Top Applications Especially For Abnormal Indian Distribution Feeder. They carried her project work under guidance of Prof. Bhim Singh.

This work deals with a novel, intelligent and robust control approach for a three phase grid connected solar PV (Photovoltaic) system, which is based on FZA-NLMF (Fast Zero AttractingNormalized Least Mean Fourth) algorithm and few other robust control techniques. Simultaneously, improvement of traditional maximum power point technique (MPPT) is done here, which enhance the tracking performance of conventional MPPT approach. Moreover, this investigation has done for both single stage as well as double stage solar PV system interfaced with local distribution feeder. These control algorithms achieve the objective of mitigation of power quality issues such as harmonics reduction and power factor correction together with extraction of peak power generated by the PV array. The system uses a PV array, a VSC (Voltage Source Converter), linear and nonlinear loads. Here, VSC is connected to a PV array to transfer the active power to the three phase load and the grid. The dependency on tuning of proportionalintegral (PI) controller is reduced because of feedforward term of the PV power. Due to this, the system dynamic response is improved, which makes the system quite robust. The system goals are to mitigate power quality problems and to provide current conditioning while operating in coherence with a weak distribution grid like abnormal Indian distribution feeder, which has poor quality of power, in terms of voltage distortions with imbalances. MATLAB/ Simulink is used to develop the model of the proposed system. The validation of proposed control is done at varying linear and nonlinear loads and under different environmental conditions on a prototype developed in the laboratory.

Rapid Cervical Cancer Detection using Neuromorphic Hardware

Students of Indian Institute of Technology Delhi, Narayani Bhatia, Shridu Verma won the award for research work of Rapid Cervical Cancer Detection using Neuromorphic Hardware. She carried her project work under guidance of Dr. Manan Suri.

In a vast country like India, trained cytologists are constrained by paucity of time and outreach and manual screening of slides leads to slow detection of disease. This is inadequate, because overburdening of human resources leads to dangerously inaccurate diagnosis, and is not time and cost effective. Our solution is an intelligent cervical cancer diagnostic support system which is a first-in-the-series of experiments to follow. Our aim is to develop low-cost, fast and powerefficient healthcare diagnostic techniques so that no disease goes undetected. We train our neuromorphic hardware solution, which is inspired by the parallelism of the brain to mimic brain-like functionality, on existing datasets of classified slide images and use a machine-learning algorithm implemented on hardware for classification. In a scenario where 99% of the solutions are software-centric, consuming huge amounts of power and employing cloud based services, our custom hardware solution is based on true artificial intelligence resulting in drastic reductions in screening times, enhanced decision-making ability and lower operational costs. It is independent of the magnification at which the pap smear images may be viewed, and is invariant to staining variations that may arise due to laboratory testing procedures in medical labs.

Ionic movement based desalinator

Students of Pondicherry University , L. R. Ravindranath, S Abilash Varan, M. Logesh, S. Arvindh won the award for developing a prototype of Ionic movement based desalinator. They carried their project work under guidance of  Dr. S. Anbumalar.

Nowadays, mostly coastal areas are in the shortage of drinking water. The areas up to 10 kms from the sea shore are affected by the sea water intrusion and getting high saline groundwater.

This is the major issue in our nation in the supply of drinking water to the people and the inability to supply water to the process industries. This leads to the public health issues, damage of economic development etc..There is an technology called reverse osmosis to reduce salinity, this technology is at the high cost of installation of equipment and RO membrane filters. The yield is also very low. In our proposed method, the filter membrane is replaced by electric polarized electrodes. The principle involved in this proposed system is electrolytic ionic moment towards the opposite charges of the electrodes.The working concept of the system is the water flows, as the water fed into system through a pipe line which is split into two directions, upward and downward flow. The salts coming from feed water flow are diverted into downward flow using the concept of electrolytic ionic movement to the opposite charges of the electrode, which are fixed in downward water flow pipeline part. The downward flow water with ions of salts is drained as reject by utilizing the gravitational force. The upward flow left free from the ions of the salts, this outlet is collected as product.

WhiteCane: A Virtual Assistant for the Visually Impaired

Students of Indian Institute of Technology Kharagpur, Barnopriyo Barua, Kaustubh Mani, Divyansh Gupta won the award for research work of WhiteCane: A Virtual Assistant for the Visually Impaired

We are using various artificial intelligence techniques to simulate a digital assistant that uses the smartphone camera to help visually challenged users in various day to day tasks. The app will take a spoken query as an input from the user.

This query will be converted from speech to text and will then be categorized into one of the many functions like Screen Description, Currency Recognition, OCR, Facial Recognition, Visual Question Answering, Object Localization etc. using the latest state-of-the-art Computer Vision and Natural Language Understanding techniques. This query, along with an image captured by the camera will be passed as an input to the appropriate computer vision model based on the intent predicted in the previous step. The result will then be spoken back to the user by our application, by using android’s text-to-speech functionality. Until now, assistive technologies in this field were usually in the form of standalone hardware devices, which turned out to be prohibitively expensive for most users. The advent of cheap smartphones allows us to use the camera to help users in day to day tasks like currency recognition, face identification, reading, etc. all through an easy to use voice based interface.

A Computational Alternative to Analyze and Understand Ebola Virus Pathogenesis in Human

Students of Indian Institute of Technology Kharagpur, Abantika Pal, Anupam Banerjee won the award for research work of A Computational Alternative to Analyze and Understand Ebola Virus Pathogenesis in Human. They carried their project work under guidance of Dr. Pralay Mitra.

Zaire ebolavirus (EBOV), one of the most pathogenic species of Ebolavirus, is a significant threat to the human community according to the World Health Organization Ebola Situation Report. Several efforts have been made to design vaccines and therapeutic drugs without much success owing to the limited binding site residue information of human protein interacting with the viral protein (VP) molecules. Such limitations stem largely from the highly infectious nature of the virus that requires specialized personnel and bio-safety Level 4 laboratories to perform wet lab experiments. Although critical interactions involving the VPs and the human proteins responsible for innate/adaptive immune responses are discovered, specific binding information between such pairs is still unknown in most cases. Therefore, we proposed a protein interaction and protein design based computational alternative to identify critical residues crucial for the human protein-VP interactions. The computational framework used an existing protein design algorithm ensuring evolutionarily and energetically favorable mutations on interface residues of a participating protein in a protein complex. The VP24-KPNA5 (karyopherin alpha proteins 5) interaction is an experimentally well-studied phenomenon concerning EBOV pathogenesis and was therefore chosen to establish the efficacy of the proposed method. The critical residues identified in the VP24-KPNA5 interface by the proposed method were in excellent agreement with the previously reported experimental findings. Additionally, the mutations of the critical residues affected the overall stability of the complex because of a sharp decrease in both the number of hydrogen bonds and possible charge-charge interactions. Therefore, we propose that the computational framework could be extended to destabilize similar host-pathogen (like Human proteins interacting with Ebola:VP35) interactions, the critical interacting residues of which are to date unexplored.

Brain wave nerve excitation for physically disabled

Students of SCMS – School of Enginnering and Technology, Kerala, Sarath S, Shilpa M Biju, Shilpa P Prasad, Midhun Raj, Sachin S, Nandha Kiran, Hridhya Jolly K won the award for research work of Brain wave nerve excitation for physically disabled. They carried their project work under guidance of Dr Sunil Jacob.

Paralysis is a problem that has been plaguing the general population ever since mankind has evolved. It is a disheartening sight to see the plight of these differently abled people not being able to bring in as much productivity as the normal population out in the real world. Of the total world population, over 29% suffer from paralyzes due to stroke or some other reasons.

Paralysed person has a clot in the brain cells that blocks the signal transmission from brain to muscle. To solve this problem we introduce the Brain to Muscle Interface for Paralyzed (BMIP) technique. The BMIP will act as a direct interface between brain and muscle by bypassing the clotting between them. This interface helps brain to control the muscle movements according to his thinking and concentration. The wearable glove that is attached to the controlling person contains the EMG electrodes which tap the excitation produced due to the corresponding movement and it is then converted into an EMG signal .We use TENS (Transcutaneous Electrical Nerve Stimulation) device that provides electrical stimulation for excitation. The headset contains 16 EEG electrodes in total (14 live electrodes & 2 reference electrodes). These electrodes are placed in contact to the necessary nerve excitation points in head. Arduino is used as an interface between the spiker shield, TENS device and the hand gloves. The person controls the movements by thought and it’s an efficient way of helping the paralyzed to do their real time activities. Link: https://youtu.be/t7iYi822lGM

Buzzing Band For Hearing and Speech Impaired

Student of Shri Vishnu Engineering College for Women, Andhra Pradesh , Saka Naveena, Panchakarla Sevya Naga Priyanka, Khande Dhana Lakshmi , Murikipudi Bindu Madhaviwon the award for research work of Buzzing Band For Hearing and Speech Impaired. They carried their project work under guidance of Prof. Ravuri Viswanadham, Prof. K. Padma Vasai .

Communication is part and parcel in every man’s day to day life. But it causes several difficulties for a person who is hearing impaired or speech impaired. Even though sign language replaces general talks for them, it fails to draw the attention of the person who is distant from the speaker. This situation causes lack of interaction among the hearing impaired students and the teacher. To overcome the problem faced by students in classroom and enable him to engage with teacher or with distant student a device that supports mass communication is needed. So to suit this requirement, the proposed solution is a device called “BUZZING BAND”. The key feature of this device is to provide one to many communications (between teacher and all students in class) in addition to one to one communication”. In order to achieve the above said communications RF Technology is preferred. Communication from one device to another is easily achieved by using RF technology. The input to the buzzing band is given with the help of a button. The button is connected to the Arduino nano to which an RF transmitter is interfaced. On the receiver’s side there will be an RF receiver which is interfaced with arduino along with a single digit display and a micro vibrator motor. The future innovation uses programming techniques so that signal is sent to various transceivers with a small time delay between each transmission to a single transceiver.

Development of Smart Wearable Body Warmers Using Graphene Coated Conductive Fabrics

Student of Indian Institute of Science, Bangalore, Nagarjuna Neella, Vaishakh Kedambaimoole won the award for research work of Development of Smart Wearable Body Warmers Using Graphene Coated Conductive Fabrics . She carried her project work under guidance of Prof. K. Rajanna, Prof. M. M. Nayak, Prof. N. S. Dinesh.

Body warmers are generally used to combat cold weather conditions across the globe. Also, they find use in biomedical i.e. electrotherapy treatments, medical blankets for patients to maintain their body temperatures and military worn jackets for soldiers in the defense forces. Moreover, some of the flexible beds employ air cushion which serves as good heat insulator to retain heat but they do not function as body warmer. Additionally, blankets/jackets made up of pure woolens/pashmina from cashmere, caprinae family animal’s fiber may prove to be good body warmer, but quite expensive and hence not affordable for middle class person/common man. Also, no control of warming is available with such garments. Warmers presently available in the market consists of fine wires/films made of metal alloys, ITO and Ga doped Zinc Oxide woven to form high resistances and consumes higher power than proposed RGO. Today’s rapid growth and progress of work in the area of wearable miniaturized electronic devices using nanoscience and engineering concepts have led to the new generation of device technology. Nanomaterials used in elements designed for creating flexible electronics/electrical and fabrics/garments due to their unique properties i.e. large SA/V and dimensionality. Commercial heaters have disadvantages: complicated fabrication and monotonous which leads to special machinery, opacity, heavy and rigidity, intolerance to acid/base, fragile, lower heating efficiency and also bulky, expensive, limited flexibility. So, looking for innovative devices with effective body warming functionality, compatible/flexibility, lower energy consumption & manufacturing costs. Presently developed/invented RGO based cloth fabrication is straight forward either by dipping/pouring solution onto the cloth and curing it suitably. Therefore, our aim is to overcome the above-mentioned drawbacks, wherein the invention provides heating device formed into required shapes, corrosion free, flexible and biocompatible.

Nano-biosensor And Methods For Detecting Potassium Ion Concentration

Students of Junagadh Agricultural University, Junagadh, Jaymin Kanubhai Jadav, Khyati Jagdish Rathod won the award for research work of Nano-biosensor And Methods For Detecting Potassium Ion Concentration. They carried their project work under guidance of Dr. B. A. Golakiya.

The invention’s outcome will help in determination of potassium deficiency from the standing crop even if the plant is not showing any visible deficiency symptoms. Potassium deficiency levels can be determined at any stage and which will help to prevent its further progress. If on determination, the plant potassium content, is found close to the threshold deficit level or deficient; potash fertilizer which is a readily available form of potassium can be applied to the field crops to recover them from the deficiency and prevent the overall yield losses. 

The invention belongs to electrochemical analysis of activity of ions in sample via a potentiometric sensor. This makes it a field portable and a unique class of biosensors that may be very useful in agricultural fields. The sensor is based upon screen printable technology, where a screen printed electrochemical cell is modified using a biomimetic component say; valinomycin- an antibiotic, one of the most potent potassium (k+) ion carrier to function as ion selective electrode. For measuring ion activity in the mentioned plant sap samples, the Ion-Selective Electrodes (ISE) are without any competition. The present research is aimed to solve the problem of detection of potassium deficiency prior as Hidden Hunger i.e. early detection to the actual morphological/visible symptoms appears in the crop plants. If the plant potassium deficiency can be determined before the symptoms, then preventive measures can be taken recover the plant health such applying potassium based fertilizer. This will also control the unnecessary usage of fertilizers, improve soil health and reduce water and atmospheric pollution ultimately reducing the cost or expenses of farming.
