SUPERSONIC AIRCRAFT PROPULSION PROBLEM
A major challenge confronting the development of supersonic passenger aircraft is the need for a propulsion system which can:
meet the current stringent stage 5 noise requirements during takeoff and landing;
operate efficiently at subsonic and supersonic speeds.
THE PROPOSED PROPULSION SYSTEM
Cameras are key enablers of self-driving and advanced driver assistance systems (ADAS) that are revolutionizing the safety, comfort, and efficiency of transportation. However, they suffer from a fundamental flaw: They capture images at fixed intervals – typically 40-45 frames per second (FPS) – during which they are effectively “blind”,
This minibus project is based on a contemporary design approach, stylized to reflect the smooth, aerodynamic form of a capsule. Environmentally conscious by design, the vehicle is powered by solar panels and can also be charged via electric power stations when necessary. This dual-source energy system supports environmental sustainability and promotes the use of clean, renewable energy.
Blood group detection is an essential process in medical diagnostics, enabling safe blood transfusions, organ transplants, and pregnancy management. Traditional blood group testing methods involve drawing blood and perform laboratory-based serological tests, such as agglutination assays, to identify the presence of antigens on red blood cells. While these methods are reliable, they can be invasive, time-consuming,
Opioid addiction is a major public health crisis that is becoming worse, 2.4 million Americans have been diagnosed with opioid dependence, and overdoses have increased, creating and economic burden of more than $78 billion/yr. Drug overdose deaths in 2021 were highest in people 35-44 years of age (62 deaths/100,000 in 2021) according to the CDC,
Plastics extrusion die design is a challenging and complex task, especially for products with irregular cross-sectional shapes. The profile (shape and dimensions) of the die exit plate plays a crucial role in determining the final extrudate cross-section.
After more than 30 years, there are still only 10 deposit law states where consumers are incentivized to recover their 5 or 10 cent deposits on beverage and water bottles and containers.
Yet, the evidence after 30 years shows that in deposit states, 75-90% of deposit bottles are returned, just so consumers can recover their deposits,
The EM Sektet Thruster is a novel propellantless electromechanical propulsion system that generates net thrust by exploiting the principles of electromagnetic induction—specifically Lenz’s Law—in a way that transfers momentum internally within the system. Unlike conventional propulsion systems, which require the ejection of mass (propellant) to generate thrust in accordance with Newton’s Third Law,
A growing trend is focusing worldwide on the development of intelligent humanoïd personal robot altogether power-efficient and cost effective. Additionnely, heterogeneous high performance edge computing is combined with robust cellular connectivity on platforms that support multi agentic ia orchestration generating in real time actionable massive data, thereby optimizing efficiencies as well as fostering innovation.
