Study reveals how detrimental the use of mobile phones is while driving in India

A study by researchers at the Indian Institute of Technology Bombay (IITB) has shown how using mobile phones while driving can distract drivers and affect their ability to handle hazardous situations. The results of the study has shown that both calling and texting while driving degrades the performance of a driver.

Study uses digital processing of archived satellite images to study the growth patterns in the Mumbai Metropolitan Region.

Supply chains are distributed and decentralised in nature, with multiple player operating in a dynamic and stochastic environment. Activities and decisions are becoming increasingly customer-centric, and there is a deluge of data. However, extracting meaningful information and prescribing effective real-time decision using the data is non-trivial.Our current works are as follows:

System dynamics methodology, discrete-event simulation, and agent based models are powerful techniques to model, understand and analyse complex stochastic and dynamic systems. Hybrid methods that combine simulation with optimisation approaches assist evidence-based robust policy decisions. The applications range across supply chain, transportation, socio-economic and healthcare systems.

Our current research activities are described below:

Our group is developing new techniques for solving difficult mixed integer nonlinear and combinatorial optimisation problems (MINLPs). These problems arise in a wide variety of scientific, engineering and business applications ranging from portfolio optimisation to design of logistic networks of a supply chain, scheduling of industrial operations and optimal layout of industrial facilities. Many of these problems are provably hard – all known algorithms to solve these problems take exponential amount of time in the size of the input.

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.
