Solar energy transport to the kitchen for cooking purposes

In India, cooking accounts for 36% of primary energy consumption. In most developing countries, wood, charcoal and dung cakes are predominantly used for cooking in rural areas, whereas LPG (Liquefied Petroleum Gas) and electricity are prevalent in urban areas. For a country blessed with generous sunshine, India can effectively utilize solar cookers to meet its domestic cooking energy requirement. Solar cookers are inexpensive and environment-friendly, but they have several limitations.

Creating Drinking water with Solar Power

Dr. Ravinder Kumar and Dr. Umanand L from the Department of Electronic Systems Engineering at IISc, Bangalore, have developed a solar hybrid desalination system. The new desalination system incurs lower construction and maintenance costs compared to traditional desalination systems while still performing optimally.

IISc Researcher’s New Transistor Design – Breakthrough in Chip Technology

Prof. Mayank Shrivastava of the Indian Institute of Science, Bangalore has invented and demonstrated a new transistor design, which can lead to a breakthrough in future chip technology. The proposed transistor has significantly better performance and scalability as compared to the technology used in current computer and cell phone chips. The invention was recently patented by IISc and related results were subsequently published by him and his PhD student K. Hemanjaneyulu.

Engineers at IISc model energy-efficient bipedal walking

A team of researchers at IISc have studied the physical constraints involved in walking and identified the optimal walking positions with minimal energy consumption. This work can be utilized in designing and developing bipedal robots – robots with two legs like humans, and human exoskeletons (think Ironman!). Prof. Loganathan Umanand and his graduate student Lalit Patnaik from the Department of Electronic Systems Engineering at Indian Institute of Science, Bangalore, carried out this study.

A novel idea for extremely small power electronic systems

Mayank Shrivastava, an Assistant Professor at the Indian Institute of Science, has come-up with a novel scheme for making power electronic systems significantly smaller. His invention, which brings different power electronic components onto a nano sized chip, can potentially create new possibilities in the consumer electronic industry.

IISc Professor wins a major international award

Prof. Mayank Shrivastava of the Indian Institute of Science has been chosen for the 'IEEE Electron Devices Society Early Career Award'. With this, Prof. Shrivastava becomes the first Indian to win the prestigious award. The award recognises his contributions to the field of micro-nanoelectronics and nanotechnology. The award will be presented during the International Electron Devices Meeting, to be held in Washington DC, USA, in December.

Energy Consumption Scheduler to reduce Electricity Bills

Want to reduce your electricity bills? Then run your electrical appliances on preplanned schedules. This is what a study by a team of researchers from the Indian Institute of Science (IISc) have found. But there is a caveat: this is possible only when our homes are fitted with smart meters that can monitor our consumption pattern.

IISc Student wins Cadence Design Contest 2015 for a chip that detects obstacles from a distance

Aditya Chowdary, an M.Tech student at the Indian Institute of Science (IISc) has been awarded the first place in the 'Cadence® Design Contest 2015' conducted by Cadence Design Systems. Aditya, from the Department of Electronic Systems Engineering, IISc, under the guidance of Prof. Gaurab Banerjee from the ECE department, has designed a device to detect approaching obstacles from a distance.

Incentivize the Individual: A Strategy for Campaigns over Social Networks

A study in Indian Institute of Science has yielded an algorithm that can allow companies to advertize their products, or political parties to campaign over social networks within a fixed budget. The algorithm ensures that the campaign reaches maximum people, through an optimal combination of mass media broadcasts and providing incentives to people having good social contact.
Social media has become part and parcel of life over the last decade. Most of us use it not only as a tool to get in touch with friends, relatives and colleagues, but also as a source of information. It is not surprising that companies are increasingly taking to social media to advertise their products; recently, politicians have been using it for election campaigns.

Scientists build system to avoid leakages in water distribution system

Researchers from IISc have made a prototype of a monitoring system that can help identify water losses and raise alarms.
A lot of resources and money is spent in purifying and cleaning naturally available water to make it potable. Loss of purified water is a waste of these resources and a financial loss to the water distribution authorities. In addition, leakage points tend to deteriorate the pipelines and also pose a risk of exposing water to bacteria and other impurities. Thus it is extremely important to identify water losses so that corrective action can be taken. “It has been observed that a large amount of water loss happens close to the source of purified water, even before the distribution network” says study author Vignesh Kudva.
