The goals of the project are multifold and include understanding and managing the complex factors impacting the lake, from invasive species, pollution, and other factors, to developing a template to use in other fresh water bodies around the globe.
As part of this ongoing effort, our teams recently installed two vertical profilers on the lake. The profilers, 12 foot-long buoys with multiple sensors that are lowered via a robotic assembly the water, measure various water quality parameters through the depth of the lake.
The interstitial pressure inside a tumor is often remarkably high compared to normal tissues and is thought to impede the delivery of chemotherapeutic agents as well as decrease the effectiveness of radiation therapy. While medications exist that…
A future covered with data-beaming sensors just got a little closer. Stanford engineers say they have produced miniscule chips that cost just pennies to make. These silicon-based components can process and relay commands, making them ant-sized controllers that can send and receive information wirelessly. Developers say the chips bridge the communication gap between sensors, machines and computers and will let them communicate back and forth.
Electrical engineer Amin Arbabian says the devices he has created are powered by the radio signals they are tuned to receive, so they don’t need any external power sources.
"The next exponential growth in connectivity will be connecting objects together and giving us remote control through the web," said Arbabian. "How do you put a bi-directional wireless control system on every lightbulb? By putting all the essential elements of a radio on a single chip that costs pennies to make."
"We’re ultimately talking about connecting trillions of devices."
