New self-propelled robotic device pinpoints leaks in pipes more accurately than existing methods

Green Car Congress

The concept was presented at two recent international conferences, and has been described in several recent papers. A 4-inch pipe section is shown for reference. Leaks in water pipes can waste up to half the water in a system; oil-pipeline leaks can lead to toxic spills and prolonged, expensive cleanup operations.

The projects include a recycling center to reduce plastic waste at Ankole Institute, in southwestern Uganda. Over the past 15 years, the term service learning has been evolving and is often now referred to as community-engaged learning ,” says IEEE Member Stephanie Gillespie , chair of EPICS in IEEE.

Perspective: Why Carbon Emissions Should Not Have Been the Focus of the UN Climate Change Summit and Why the 15th Conference of the Parties Should Have Focused on Technology Transfer

Green Car Congress

Unfortunately, this conference focused primarily on setting a cap on carbon emissions and providing financial aid to developing countries to build capacities to adapt to the negative impacts of climate change. Do we really want to be remembered as the generation that wasted another decade? References. 293-308 doi: 10.1287/mnsc.1050.0437.

A Circuit to Boost Battery Life

Cars That Think

It tries to make the output voltage (VDD) equal to the reference voltage by controlling the current through the power PFET. In the basic digital design [right], an independent clock triggers a comparator [triangle] that compares the reference voltage to VDD. V instead, wasting some power. V, but VIN is 0.95 Source: S.B.
