- Presenter:
  Prof Rajkumar S. Pant, Aerospace Engineering
- Venue: GG 002
- Abstract / Poster:
  This talk will provide details of SeRWiCTA, a system for addressing the last-mile communication needs of remotely located and under-privileged communities.The system is envisaged to be a totally self-contained and easily re-locatable system. It will consist of broadband telecom system (data+voice) mounted below an aerodynamically shaped balloon filled with a Lighter-Than-Air gas (e.g., Helium or Hydrogen). This balloon will be anchored to a winching and mooring system using a conducting tether, so that it can be raised and lowered as and when it is to be deployed to address a particular communication requirement. To increase the mobility and permit access of SeRWiCTA to remote communities, the entire system will be mounted on the chassis of a general-purpose truck. SeRWiCTA can also be used as a system for several other possible applications such as disaster management, tele-medicine, education, e-learning and e-governance.

  Dr. Sarbani Banerjee Belur, Senior Project Research Scientist, Gram Marg
- Venue: GG 101
- Abstract / Poster:
  In the modern digital age, â€˜Right to Ubiquitous Broadband Connectivityâ€™ is a basic human right of individuals, irrespective of where they live, their socio-economic status and gender. Internet has played a major role in the connectivity revolution by enabling a bridge to the digital divide through benefits of its usage. India has a very large rural-urban digital divide. While urban India is almost completely covered both through voice and Internet, rural India still suffers from inadequate connectivity with approximately 50,000 villages which do not even have voice connectivity and 6,40,000 villages that needs Internet connectivity. Hence, there is a need for broadband penetration in rural areas overcoming the various barriers and challenges that dissuades connectivity outreach to the rural areas. Thus, for enabling broadband connectivity to rural India, some of the important issues that needs to be addressed are â€“ technology feasibility, affordability of the technology and sustainability of the technology at the village level. Thus with the vision of enabling rural India digitally, Gram Marg was formed. Gram Marg is the brand name for the Rural Broadband project at the Department of Electrical Engineering, IIT Bombay. Gram Margâ€™s main aim is to develop solutions and digitally empower rural, remote, under-served areas in India through Internet connectivity contributing to national growth and development. Gram Marg is involved in research, development of solutions and technology innovation to reach the rural, remote areas of India.

- Presenter:
  Chayan Bhawal, PhD student
- Venue: GG 103
- Abstract / Poster:
  The standard eigenvalue problem finds widespread applications in different areas of engineering e.g., structural stability analysis, spectral clustering in image processing, dimensionality reduction in machine learning, Google page rank algorithm, control theory etc. Interestingly, a generalized form of the standard eigenvalue problem also finds applications in different areas of engineering. In this talk, we embark on a journey to understand the generalized eigenvalue problem. In this journey we find analogies between the standard eigenvalue problem and the generalized eigenvalue problem. In the process, we also look into a few applications of the generalized eigenvalue problem.

An Introduction to PWM techniques for Multi-phase Induction Motor
Thu

Oct

Time

- Presenter:
  Satish Belkhode, Research Scholar
- Venue: GG 103
- Abstract / Poster:
  Induction motor is considered as the workhorse of industry. Since the invention of three-phase ac system three-phase Induction Machine became popular everywhere. But, due to the recent development in the controllers and power electronic devices, industrial applications are not limited by the conventional system of supply. Thus, Multiphase machines are considered as a powerful choice for the applications requiring high reliability, smooth torque response and high energy density. However, the increase in number of phases increases the complexity in control. Thus, the PWM techniques for five-phase induction machine require a special attention on reducing the complexity and handle additional issues. In the talk, the review of the issues related with the implementation of PWM techniques on five-phase induction machines will be discussed with the explanation of recent PWM techniques for the same.

- Presenter:
  Jithu Krishna, M.Tech, Control and Computing
- Venue: GG 303
- Abstract / Poster:
  The last three decades have seen fast advancements in the field of autonomous vehicles. For a platoon of vehicles moving in a straight line it is required to keep a safe distance between them. In this talk, we discuss how this is achieved for a semi-autonomous vehicle using adaptive cruise control. Experimental results will be shown using these laws when applied to a tricycle with provision for human pedalling. There is an added advantage of energy saving because of human pedalling which extends the battery life of the vehicle.

An On-Line Radio Access Technology Selection Algorithm in a LTE-WiFi Network

Aug

Time
15:30
- Presenter:
  Arghyadip Roy, Research Scholar, Infonet lab
- Venue: GG 302
- Abstract / Poster:
  In a Heterogeneous Network (HetNet) comprising of multiple Radio Access Technologies (RATs), a user can be associated with a particular RAT and can be steered to other RATs in a seamless manner. To handle the rapid growth of data traffic, offloading of mobile data to Wireless Fidelity (WiFi) has been proposed in a Long Term Evolution (LTE) based HetNet. We consider an optimal RAT selection problem in an offload-capable LTE-WiFi system with an objective of maximizing the total system throughput subject to a constraint on the voice user blocking probability. An on-line algorithm for optimal RAT selection is proposed based on a Relative Value Iteration Algorithm (RVIA) centric Q-learning approach. The proposed algorithm can be implemented without any explicit knowledge of arrival processes of voice and data users.

- Venue: GG 103
- Abstract / Poster:
  Quantum computation is an emerging discipline which has itâ€™s lucid applications in varieties of branches of science and engineering. To perform realistic applications for the same we need physical systems. These physical systems demand their mathematical representations. The state of a simplest physical system (ie. Spin- 12 particle) can be assumed as Qubit, which is the basic building block to process quantum information. This presentation is for beginners which will cover Pauli spin operators, representation of a qubit on Bloch sphere and a detailed mathematical procedure to write two qubits parametrized entangled density matrix. Further the illumination will be given to Pure Vs. Mixed states and mathematical tools for detection and quantification of entanglement.

- Presenter:
  Ramchandra Bhosale, PhD
- Venue: GG 103
- Abstract / Poster:
  Fuzzy Logic based non linear controllers are being used in wide number home appliances. It provides the control actions which are similar to human reasoning. The Fuzzy logic control fundamentally uses the linguistic variables which are vague and imprecise but these are the building blocks of the fuzzy logic controller. These controllers are robust and do not demand the knowledge of the plant mathematical model of the controlled system. This controllers are designed based on the knowledge of the operation of the overall system. Such controllers are also incorporated in the micro grid applications in the power management, charging algorithms, converter control etc. This presentation includes the application of Fuzzy logic controller in control of the storage system in the DC micro grid.

  Kamini Sabu, PhD (DAP Lab)
- Venue: GG 303
- Abstract / Poster:
  Prosody helps in conveying the proper meaning of speech along with the emotions. It is well-agreed that students' reading should not be mere pronunciation correctness, but should also involve reading fluency in the form of prosody. Pitch, duration, and intensity are known to be the good indicators of prosody. We use these features to predict reading fluency of children and to evaluate their reading capabilities.
