Science Nation - Firefighter Tracker

submitted by: nsf
Firefighters risk their lives every time they run into a burning building. But, new technology may soon be watching their backs, no matter how far they venture into the flames and smoke. With support from the National Science Foundation, TRX systems is developing a new sensor system that can track firefighters where GPS units often fail. Firefighters who are currently testing the new system wear a portable device called the Sentrix tracking unit, which is actually a suite of sensors that can...

Physiological Pathway Diagrams

submitted by: RGD.Videos
Are you looking for a more intuitive way to visualize pathway information? RGD's newest video tutorial about the Physiological Pathway diagrams will help you navigate these interactive diagrams for use as either a research or study tool. In this video, we will: • Locate the Physiological Pathway Diagrams on RGD’s website • Walk through a particular pathway diagram • View relationships between levels of organization • Learn every one of the controls attached to the diagrams

Metabonomic profiling of the gut microbiome: Implications for human health James Kinross, Imperial College, London

submitted by: dougramsey
Microbial-mammalian metabolic cooperation is defined as the human ‘metabonome’. Transgenomic co-metabolic interactions within the metabonome greatly increase system complexity and this presents a significant challenge for elucidating the mechanisms by which the intestinal micro biome influences the host phenotype. By measuring and mathematically modelling changes in the levels of products of metabolism found in mammalian biological fluids and tissues, metabonomics offers fresh insight...

Robust source-seeking hybrid controllers for nonholonomic vehicles (experiment)

submitted by: mayhew

This video shows an experiment involving a mobile robot, an IR-camera vision system, and a wireless network. The robot queries the vision system for position information. The robot uses this position information to simulate a potential function in its environment. The hybrid controller uses these measurements in a coordination of vehicle steering and an optimization algorithm to drive the vehicle to the minimum of the function (shown as a blue 'x').
