Classical results in information theory focus on coding theorems which provide sharp guarantees for reliable communication and data compression when one allows for arbitrary delays for achieving a desired probability of error. But in real systems such as multimedia communication systems, delay constraints are fundamental and non-negotiable. For such delay constrained systems, except in rare cases, determining the optimal system performance is a highly intractable problem. Prior to our work, performance limits were derived using disparate techniques and arguments.

The Indian securities market has seen an meteoric increase in algorithmic trading that involves the use of computerised algorithms for determining trading decisions. This usually takes the form of high frequency trading wherein orders are issued with an extremely high frequency. This has been further facilitated by location of servers of traders in physical proximity of the exchange (called colocation). There is concern among regulators worldwide about the impact of algorithmic trading.Prof.

A common problem in process design is the selection of optimal operating condition, which involves considering simultaneously multiple response (output) variables. This type of problem is known as multiple response optimisation (MRO) problems. Multiple response problems are quite prevalent across various disciplines of science and engineering. In this context, responses are the quality characteristics which attribute to the quality of process or product. In this context, responses may be catogorised into three different types, viz.

Game theory analyses multi-person decision making where each agent’s welfare is dependent on actions of another agent. We work on game theoretic mechanism design that seeks to construct institutions that lead to desirable outcomes in society. An example of such an institution would be the ‘Boston School Choice’ mechanism that is used to admit students in US public school system. Apart from this, we also study formation bidding rings at auctions.

India may climb in top 20 in country competitiveness ranks, and opportunities to break-out in technological competitiveness seem promising as focal firms of Indian origin (FFIOs) build capabilities for next levels on stages of international competitiveness (IC). However, international competitiveness in emerging industries is less satisfactory (Fig.

SCM is of course, the management of flow of goods from supplier to transporter to production department to sales and eventually to customer. The objective of SCM is to reduce overall costs by introducing effective coordination and cooperation across echelons. Several sophisticated analytical tools and optimization software solutions exist in the marketplace and academic journals to help organizations meet this objective.

Scientists from IIT Bombay assess the impact of market demand for coproducts and carbon capture on the profitability of microalgae biorefineries

Gram Marg, Rural Broadband project IIT Bombay has joined hands with the Government of India (GoI) to address the issue of Internet connectivity challenges facing rural India. BharatNet has been an GoI initiative that aims to deploy fibre optic cable connecting Gram Panchayats across all states of India by the year 2019. ,
 

At the National Centre of Excellence in Technology for Internal Security (NCETIS), our group has conceived, designed and developed an emergency communication system for Public Protection & Disaster Relief (PPDR). This system facilitates realtime video streaming by first responders (police / anti-terrorist forces / disaster response teams) to maintain direct communication between team members in the field and to provide a global view of the operation at a single point.The system operates in sub-GHz frequency band and has been designed in consultation with elite forces in the country.

While digital tuners are commonly used by musicians to set precisely tuned pitches in an instrument, instrument beginners can benefit greatly from an automatic device that measures the overall ‘goodness’ of the sound in order to provide corrective feedback on the articulation skill of the player. Intonation, dynamics and tone quality are important attributes of musical sounds that can be estimated by acoustic signal analyses.

The country has been witnessing issues of sustainability in many livelihoods programme in past in different places. In most of the cases, post project period, the initiative faces challenges to become sustainable. This has been an issue with most of the development activities.

In the above context, our research group had envisaged a model as solution. After initial efforts, our group found that a model which includes an implementable market linkage as an essential component, can sustain a livelihood programme.

It is increasingly becoming apparent that technology can enhance the productivity of resource-challenged agricultural practices in developing countries. In India, the agriculture uses 80% of available water and out of which 40% water is wasted. Over irrigation causes the leaching of micro and macro nutrients from the soil contaminating the ground water and reduced crop yield. The efficiency of water usage in the agricultural fields needs to be improved. With this motivation, we have developed a low cost soil monitoring system.

In a resource-constrained society in developingnations like India, the importance of health care infrastructure allocation is often undermined and overlooked. We have looked into the issue of access from the perspective of policy making and resource allocation as well as from the people’s needs and demand. While affordability, accessibility and availability varies among the heterogeneous urban fabric in urban India, our research focus has been on the formulations of (i) strategies to ensure access to facilities and to

Lack of standardised sustainable habitat design guidelines for low-income housing plays an important role in determining the poor quality of life in these settlements, particularly in the slums. Our work investigates process-driven pathways for developing and delivering sustainable habitat design guidelines using socio-technical frameworks. We employ mixed-mode research methods where we integrate the depth of engineering with the breadth of social science to understand low-income habitat from the perspective of people, places and practices.

Ocular trauma is one of the most common types of combat injuries resulting from the exposure of army/security personnel with improvised explosive devices. Specifically, in India and other terrorism affected nations, there are several cases of injury of human eyes caused by the blasts. Ocular blast injury mechanisms are complex, and trauma may occur through various injury mechanisms. Since blast field measurements are not trivial, we used computational modeling to reconstruct the TNT blast events on an anatomically accurate human face and eye.

With growing need for security and safety of public from war, terrorist activities and anti-social activities, it has become very important to design and develop in-house skills for the detection of various analytes such as explosives, chemical and biological warfare agents and substance abuse. Currently in India, only canines are the best working explosive detection systems. In case of landmines, metal detectors are used extensively along with the canines.

While tracing veins in patients, there is a difficulty in locating the veins—especially in children, darker skinned and obese people which leads to unnecessary multiple needle pricks that causes pain and injury.

The vein tracer has been designed as a simple light-weight device that humanises a simple technology (NIR Spectroscopy), helping medical practitioners easily identify the veins during vein-puncture procedures, thereby reducing patients trauma.

Features

 ■ The vein detector is convenient, light weight
