Snippets: Monitoring crop diseases, infrastructure health and wildlife

Gayathri Gopalakrishnan Agriculture Sensors Wildlife

"If you can't measure it, can you fix it?"  One of the greatest challenges faced by almost everyone working in a clean technology field - water, agriculture, energy, climate, forestry, wildlife, soils, corporate sustainability, smart cities - is the challenge of monitoring. At its essence,this is the challenge of what needs to be measured, how often and how accurately can it be done. Traditional methods of monitoring have involved sensors (of different levels of accuracy) placed in specific locations and the data removed and processed off-site by engineers and field analysts at specific time intervals. This is a time-consuming process,...

Last time we looked at the kind of applications in clean technology where using virtual reality or augmented reality systems are making a significant difference.   But, how do these systems work?   Most AR and VR systems can be broadly classified as follows.     These systems can be divided into 1) the hardware required to get the data, process and display it 2) the software needed to develop simulations of the systems being studied and create virtual objects and 3) the server where the data are stored and processed and where machine learning algorithms can be deployed to...

What do the terms Virtual Reality (VR) and Augmented Reality (AR) bring to mind? Hollywood movies like “Black Panther” with the crazy action sequences where cars and airplanes are controlled from a laboratory, games like World of Warcraft with your gaming character moving through all the different locations, Pokemon Go and hunting for the prize in an actual physical location, Star Trek holodecks where you could explore completely different planets and surfaces… the list goes on and on. The one thing that all these examples have in common though is that they all come from the entertainment industry.   Now,...

Snippets in Clean Technology and Data Science: Wildlife and Ecosystems

Gayathri Gopalakrishnan Sensors Wildlife

A fun and exciting area to use data science in clean tech is in monitoring wildlife! This sector uses a combination of computer vision, remote sensing, artificial intelligence among other tools to help us track wildlife across the world. Here are a few examples of the kinds of problems and technologies that are in play these days! First, An interesting study came out of California recently, where scientists from the University of Delaware, University of California at Davis and the US Geological Survey partnered to track the movement of waterfowl in the region. My first question when I read the...
