89,789 | This is a great example of how micro-grid systems can be implemented in communities to encourage renewable resource usage and localized production. To plan and install Microgrids correctly, engineering modelling is needed. Multiple simulation tools and optimization tools exist to model the economic and electric effects... | Decentralized energy | 0.78115 |
89,790 | The predominant PV technology is crystalline silicon, while thin-film solar cell technology accounts for about 10 percent of global photovoltaic deployment. : 18, 19 In recent years, PV technology has improved its sunlight to electricity conversion efficiency, reduced the installation cost per watt as well as its energ... | Decentralized energy | 0.78115 |
89,791 | Wolfbite is a 3D printing adhesive to facilitate the bonding and removal of nylon and nylon blend prints from glass and ceramic build plates. The product was formulated to solve the problems of warping and adhesion that are inherent when 3D printing with nylon. | Airwolf 3D | 0.78115 |
89,792 | The original Airwolf printer (v.4) was derived from the Prusa Mendel and Mecano Air designs, hence the name "Airwolf. "The company started shipping fully assembled 3D printers in June 2012 from their garage in Newport Beach, California. The first printer was sold to Lars Brubaker and Kevin Pope of MatterHackers.

89,793 | Airwolf was founded in May 2012 by Erick Wolf, a garage mechanic and patent attorney with a mechanical engineering degree, and his wife Eva. The inspiration for the company came from a 3D printer that Erick bought just before Christmas 2011. After encountering difficulty with his goal of getting the printer to print re... | Airwolf 3D | 0.78115 |
89,794 | The AW3D HDx was introduced in May 2014. It is a 3D printer can build prototypes out of engineering-grade materials like polycarbonate, bridge nylon and nylon 645. The HDx uses the company's JRx hot end and can continuously hold temperatures of up to 599°F, which allows 3D printing in more durable materials. | Airwolf 3D | 0.78115 |
89,795 | In mathematics, Mumford's compactness theorem states that the space of compact Riemann surfaces of fixed genus g > 1 with no closed geodesics of length less than some fixed ε > 0 in the Poincaré metric is compact. It was proved by David Mumford (1971) as a consequence of a theorem about the compactness of sets of discr... | Mumford's compactness theorem | 0.781147 |
89,796 | Upon completion of the network in 2014, RSN will cover a distance of over 900 kilometers at depths of up to 3000 meters. Implementation of the OOI Regional Scale Nodes is led by the University of Washington's (UW) School of Oceanography, the UW Applied Physics Laboratory, and L-3 MariPro. Live RSN data from >100 seaflo... | Regional Scale Nodes | 0.781145 |
89,797 | In organofluorine chemistry, many perfluorinated compounds are prepared by electrochemical synthesis, which is conducted in liquid HF at voltages near 5–6 V using Ni anodes. The method was invented in the 1930s. Amines, alcohols, carboxylic acids, and sulfonic acids are converted to perfluorinated derivatives using thi... | Tafel rearrangement | 0.781145 |
89,798 | Major preoccupations of neuro-enhancement include optimization of child development factors and delaying, reversing or mitigating brain aging. Attempts to enhance human memory and learning ability have a long history in science (and proto-science). | Neuroenhancement | 0.781144 |
89,799 | Sleep is investigated for potential ways to leverage it for acutely (e.g. via complex analogical problem solving or sleep onset periods as creative sweet spots) or chonically improving types of creativity. There is research into interventions to enhance sleep as in improving sleep quality, efficiency (sleep latency), a... | Neuroenhancement | 0.781144 |
