Electrical engineering may seem like a boring profession, especially if the first person that comes to mind is the public utility repairman who fixed the neighborhood power grid. This is such a great hub. Thanks for the information. I’m beginning to understand how great solar power is and this information just adds to that learning, thanks. It’s really amazing that we can use sunlight to generate energy and provide free use of home products like the common attic fan or any device that uses solar energy. That takes quite a lot of time, so Malovichko and his colleagues from the Skoltech Center for Data-Intensive Science and Engineering (CDISE) have proposed to approach this challenge in a different way. Their solution for the inverse EEG problem directly “backpropagates” measured signals from the skin inside the head down to the cortex. This requires reframing the whole task as a Cauchy problem, a type of mathematical problem that is known to be unstable for EEG: that means even slight deviations in the input, for instance, from unavoidable measurement errors, can significantly skew the result. Yet recent research has brought new approaches to tackling these unstable problems efficiently, and the scientists used them in their research. VMWare and Microsoft have a competitive relationship, that’s probably another reason why no Windows based development has occurred. This product has a high price tag, and is licensed per CPU. The ongoing support costs are also based on the number of CPUs. Drivers who listen to cell phone conversations are distracted even if they do not talk, exhibiting similar behavior as people who have been drinking. The study conducted at the Center for Cognitive Brain Imaging at Carnegie Mellon University in Pittsburgh used brain imaging to document that when driving and listening, activity in the parietal lobe, the portion of the brain associated with driving, was reduced by 37%. Another interesting use of cellulose in electronics is found in transparent cellulose films. As discussed before, cellulose can form networks of microfibers with proper preparation. Under the proper conditions, cellulosic microfiber networks can be made such that they are transparent to visible light. Transparent paper can be processed to tune light transmission from nearly 100% down to typical opaque paper. As transparent paper is made of the same robust microfibrillar cellulose as mentioned before, it remains a very durable material. Transparent paper could be a viable alternative to plastic films as an electrical device substrate in applications where flexible circuits are common, like conductive screens, OLED substrates, or solar cells. Interestingly, transparent paper could have a very promising future in conductive screen technology due to the lack of glare associated with cellulose films that seems always present in other film materials (Zhu et al., 2014).
