The accumulation of particles, dirt, and grime on the surface of the solar panel degrades the performance of the solar panel in the same way as it does on a cloudy day. This means that solar panels are not being used properly. However, over time,
Our project aims to revolutionize emergency medical services in rural communities by introducing a network of drone-based ambulances. The current healthcare infrastructure in these areas faces numerous challenges, including long travel distances, limited resources, and difficult terrain, which often lead to delays in accessing life-saving medical care. By leveraging drone technology,
Transformer efficiency is the ratio of the output power to the input power. Output power is always lower than the input power due to energy losses. Besides measures put in place to reduce energy losses; including use of laminations, soft iron core and copper wires. Commercially used transformers are still about ninety percent efficient,
We are developing a new generation of solid fuel combined heat and power microturbine system. Fuels include woodchips, waste plastics, waste biomass, fuel pellets, agricultural waste, and any combustible solid, as well as conventional fuels such as propane, natural gas, heating oil, waste oil, vegetable oil, etc.
It is often desirable to deliver extremely high power laser output by fiber optics rather than free space, e.g., for surgical, welding, spectroscopy, yet coupling very high optical intensity into even ‘larger silica core’ fiber is replete with challenges.
The I-5 and I-84 Realignment and Additional Access into the Area
The I-5 and I-84 interchange in Portland Oregon is the worse congested and most accidents for the state.
Multiphase electric machines possess several advantages when used in the electric drive system for automotive, aerospace/defense, rail, marine, and manufacturing industries. The performance of an electric drive system in extreme working conditions is extremely compromised. An electric drive suffers from torque derating, a decrease in efficiency,
Our living environments are always patterned or textured. 2.5D structures, from rough surface textures to more explicitly-designed patterns, are ubiquitous and are interwoven with 2D planar surfaces. These 2.5D textures assist human perception, enabling us to feel, understand, and discover additional environmental information.
Recognizing the importance of 2.5D structures,
The device is a dual mode engine for aircraft. Today's engines are either for flight within the atmosphere (turbo jet) or space (rockets) but not both. In the attached picture you will see a simple non-detailed cross section of a turbo jet engine. The illustration show the engine in turbo jet mode and rocket mode.
