Audio signal processing for music analyses

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.

Community skilling and capacity building livelihoods model for tribal community in Mumbai

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.

An affordable in-house developed system for precise irrigation

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.

Access to healthcare: Healthcare infrastructure planning for disadvantaged groups

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

Data-driven design heuristics for sustainable low income settlements

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.

Blast loading on human eye: Injury mechanism and risks quantification

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.

Handheld explosive detectors

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.

Low cost vein tracer for blood banks and pathology labs

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

Macro and micro scale study of artificially structured soil: A slope stabilisation perspective

Mountainous land is widely distributed throughout the world and the soils in such area are subjected to many construction projects. The long term durability and fitness of the projects depend upon the soundness of the engineering behaviour of the soil. Due to the inferior geotechnical properties, sometimes mountainous soil poses serious threats on the projects during and/or after the construction. To improve their properties, lime can be utilised as it is cost-effective and easily available additive.

Collapsible helmet design for Indian two-wheeler users

A helmet is an essential safety device but, lugging around a bulky helmet is so inconvenient that many two wheeler riders and their pillions would chose to go without one—even though this may be a fatal choice. While rules have come into place for enforcing helmet usage, there have been no noticeable design interventions for improving the Indian two-wheeler driver and pillions helmet experience. This is in spite of many improvements available in materials and technologies over the years.

Lighting for heritage monuments

As tradition, all of us visit temples for worship, but we never appreciate the beauty and efforts taken in building these lovely artifacts. Lighting that can enhance heritage temples and forts by night – is currently done in a fairly insensitive manner. Nails are driven into century old stone walls, irreparably damaging the sculptures, murals and inscriptions inside the temples. The

Lightweight palkhi designed for use at Shri Mata Vaishno Devi shrine

The Vaishno Devi Palki has been redesigned for improving the conditions in which Palkhi bearers make a livelihood. The existing heavy Palkhi which is 65 kg rests upon their shoulders causing injury and long term muscle damage in the Palkhi bearers.

Our team has designed a new Palkhi in stainless steel for the Shree Mata Vaishno Devi Shrine Board. This has a longer life and nil maintenance issues compared to the previous palkhi.

Window mounted solar oven

If we want non renewable energies to make real, large scale impact, they need to get integrated into modern lifestyle. For example, if we want the space-starved, time constrained urban dweller to adopt solar energy, it should be made as convenient for them as switching on their microwave ovens.With this aim, our team is developing the ‘window mounted solar oven’. It utilises solar energy for cooking and dyeing in a user friendly way.

Brick-making to get more efficient and ergonomic

Brick manufacturing in India is a traditional and unorganised industry. Of late, due to rapid urbanisation, high rise metropolises and a spurt in real estate development, brick making has become one of the most flourishing and booming industries. There are more than 22,000 brick kilns in India engaging more than 3 million (30 lakhs) workers. The brick kiln industry is an unorganised sector in India where most of the jobs are performed manually.

Byclip: Bicycle parking rack

Byclip, a bicycle parking rack, is a solution to the need for organising large number of bicycles and prevent their lateral fall because of random parking practices. Bicycles falling atop one another result in damage to bicycle frames, wheels, components, etc. Such damages further deter cyclists from using such parking spaces especially in large campuses like institutes, software complexes, apartment complexes, etc.
