Wings in Figure are in tandem configuration to have the capability of heavy payload applications due to efficient lift generation. Blended body fuselage and End plates are
configured with tandem wing, in order to acquire the low power consumption for long endurance by reducing the drag over the Unmanned Aerial Vehicle. Since blended body fuselage and end plates are configured with tandem wing, it was found that there is a lack of lateral stability in the mentioned new configuration with the tandem wings, end plates & blended body fuselage. To overcome that instability, twin-tail with the dorsal fin is configured with tandem wing, blended fuselage, and endplates. All together putting a novel configuration with low power consumption & high stability ...

As COVID-19 has shown, challenge and crisis cross borders – impacting everywhere on Earth. However, innovation and ingenuity are also not constrained by geography. Detection of COVID-19 is an opportunity to find and apply the best and brightest of humanity. We're going to improve our design replicable, low-cost tool and resource to aid viral detection of the COVID-19. Computer vision as Deep Learning with OpenCV is used here, and can serve as a backup to the work done in the laboratory.

What're the goals of this project? 1) Detecting COVID-19 in X-ray with OpenCV; and 2) Detecting COVID-19 Virus Cells with OpenCV.

What hardware we have used? 64-bit Windows 10 PC, Raspberry Pi 3B+, and Jetson Nano.

First, we ...

A near frictionless electromagnetic vehicle braking system is described that includes a solenoid axial single-circuit direct current (DC) electro-permanent magnet configuration in the shape of a ring, controlled via an activator/regulator that interprets pressure applied to a vehicle’s brake pedal mechanism, and powered by an alternator/transformer device in conjunction with the vehicle’s battery.

When not in use, the electro-permanent magnet firmly holds the rotor “clamped” in place with its magnetic field, creating the “park” position. But when activated, the electrical charge travels through the spooled magnet wire initiated by the activator/regulator (which interprets the signals from the foot brake mechanism), and sends an appropriate electrical charge from the vehicle’s battery into the electro-permanent magnet, interacting with the magnetic core ...

There has been a lot of news regarding the banning of the sale of internal combustion engine powered automobiles, in favour of electric motor powered automobiles. What has not been appreciated is even if they did ban the sale of ICE powered automobiles it would take years for the electric powered automobiles numbers to affect the total numbers of automobiles in use. Presently there are 1.42 billion cars in operation worldwide, including 1.6 billion passenger’s cars and 363 million commercial vehicles. In 2018, more than 70 million cars, and around 25 million commercial cars were produced worldwide, while around 2.2 million passenger electric car sales.

My idea is to convert existing ICE cars into hybrids, to run on electric ...

So far we are losing the war with rodents. Higher and higher poisoning did not help. Is it possible to stop them? Yes, it is possible without even needs in poisonous substances. The only way to stop them is to deprive them from access to food. That could be done by putting glass chanks on their way, the only material which them unable to cut trough. That could be done by adding containing glass layers to the bottom side fundaments, wall panels, protective collars on cables, and pipes and tiles belts around of buildings. Additionally, containers filled with eatable for them products should have form and design effectively preventing intrusion.

These steps will safe food and help to prevent ...

Reduction of energy spend and boosting of throughput is of paramount importance to maximize gas separation efficiency. Waste heat energy has a major role in cost of the separated gas. In order to reduce waste energy and thereby reduce cost and increase throughput I have successfully developed a new concept after spending several years to research. The concept is described below.

Positive and negative Electric field is applied in front of two oppositely facing blowers respectively and dust passing through the electric field is excited and excited dust particle at middle aggregate and due to higher weight fall down

We have scaling parameters that cover particle-gas concentration velocities, lengths, electrostatic changes, temperature, interaction parameters, including collisions or chemical reactions. ...

In a door to door mobility scenario the last mile is the most critical issue.

Public transportation must stop at selected terminals and private transportation not always have access. To solve the problem while in most localities, especially considering the need for parking as the biggest obstacle to an effective door to door direct flow. To optimize such requirement a mobile, easy to transport, lightweight and small vehicle would be needed.

Our system, slightly larget than a skateboard table, satisfy such requirements and, being powered by solar generated electric engines is also a pollution free vehicle. The system consist of a 85 cm high vehicle, with carry on provisions, movable like a trolley suitcase, that can be transported everywhere, ...

Waveco is a technology innovator dedicated to contributing to the global green energy transformation. We do that by adopting the proven principle of the wind turbines to the ocean space beneath the waves.

Air and water are both fluids and follow the same physical laws. But water is much denser. While the wind turbine blades sweep over a diameter of up to 200 meters, the diameter of the Subwave turbine will be up to 20 meters.

The Subwave turbines operate below the active wave zone, safely away from the harsh surface environment, with its storms and marine growth. The turbines hang in cables from sturdy buoys on the surface. Wave energy is relayed to them via these ...

You step on the platform, witch is big enough for your whole foot, and push a button to go up or down. It is run by your 24v drill batteries. The handle has the button you hold on to in order to go up or down. Holding on to the handle will give you better stability, especially going down. I don't know if you have ever thought you were all the way down and you had 2 steps to go, wow that was a big step to the ...

After reading numerous articles about football helmet design and the comments that "there will never be a concussion-proof football helmet," I am concerned about my grandson who plays high school football. I am also an aerospace materials engineer who does not like the term "never." If we subscribed to the adage that we would "never go to the moon" we wouldn't have much of the technology that we have today.

All of the articles that I have read about football helmet design focus around making the inside of the football helmet energy absorbing and always keeping the outer "shell" hard and rigid. There have been experiments with soft layers over the outer shell but they tend to just relocate ...
