The performance of a solar plant installed at the Indian Institute of Science campus, Bengaluru has been found to be as good as other well-performing ones in the country, according to a team of researchers at the Divecha Centre for Climate Change. Armed with the data from a solar system they monitored in the IISc campus, the team shows that solar installations can perform reasonably well in the city. They also show that seasonal changes have significant impact on the performance of the system; with a reduced efficiency when the module is too hot.

Measurement of Land Surface Temperature (LST) is important for hydrology, environment science and many associated fields. Prof. D. Nagesh Kumar of Department of Civil Engineering at the Indian Institute of Science, Bangalore, and his team have proposed a novel methodology that can accurately predict LST at high resolution even under cloudy conditions. Their work has been published in the ISPRS Journal of Photogrammetry and Remote Sensing.
Take a deep breath. The chances are that air filling your lungs is impure and polluted with deadly gasses like carbon dioxide. According to the World Health Organization, every year around two million people die prematurely due to air pollution.
Scientists at the Indian Institute of Science, Bangalore have proposed a new force sensor that can detect changes in forces as small as ten nano-Newtons. That’s one hundred millionth of a Newton, the unit of force! The proposed sensor uses a special crystal with specific resonation characteristics that can sense these tiny forces. Sensors that detect small forces are used in the fields of chemical sensing, bio sensing, temperature sensing, humidity sensing, pressure sensing, and stress sensing. An eight-member team from the Department of Electrical Communication Engineering and the Center for Nano Science and Engineering headed by Prof. T. Srinivas, is behind this innovation.
The persistence of a thin, surface layer of fresh water in the Bay of Bengal (BoB) is known to have a great influence on weather and climate across South Asia. However, the mechanism that sustains this low-salinity layer has remained a puzzle for ocean scientists.
Prof. Debasis Sengupta and his colleagues G. N. Bharath Raj and J. Sree Lekha of the Center for Atmospheric and Oceanic Sciences, Indian Institute of Science (IISc), Bangalore, with M.Ravichandran of the Indian National Center for Ocean Information Services, Hyderabad and Fabrice Papa of the Indo-French Cell for Water Sciences, IISc, have presented the first evidence that submesoscale fronts may be the key to the sustenance of a fresh layer in the north BoB.
A bicycle is budget friendly, being cheaper than most other forms of transport, eco-friendly requiring absolutely no fuel, does not need much of parking space, helps keep the chic city-dweller fit without having to shell out for monthly gym subscriptions, and requires a very low maintenance. Put like that, it sounds like an ideal mode of transport. And yet, for most of us having owned a bicycle during our childhoods, a cycle is only a symbolic reminiscent of the adventures of our junior years and nothing more.
Bangalore presents numerous opportunities in terms of economic growth, technological advances, cultural exchange but its problems of access and provision of basic services of housing, water, sanitation, excessive resource consumption, and pollution persist. Can a city hope to alleviate the problems of population concentration while still allowing the opportunity for prosperity?

Retail competition in the power sector equipped with smart grids can help make power distribution in India more efficient and economical, suggests a study. Akhil Joseph from the Department of Management Studies, Indian Institute of Science, has researched the viability of a retail competition scheme, akin to choosing a cellular network provider, for the future of electricity distribution system.
Hilly regions, especially ones which receive heavy rainfall and are located in earthquake-prone regions, are likely to suffer frequent landslides. Landslides occur when masses of earth or rock collapse from a mountain or cliff. They can pose a big threat to life and property. The Indian state of Sikkim is no exception. Situated in the Himalayan belt, the region faces frequent landslides. The recent earthquake in adjoining Nepal triggered many landslides in Sikkim. This motivated a recent study by Naveen James and Prof. T G Sitharam from Department of Civil Engineering, IISc, to assess the vulnerability of Sikkim to landslides, especially those induced by earthquakes.
