High technology paints for enabling autonomous driving

Radio waves and light sensors are commonly fitted to autonomous vehicles for detecting the speeds and distances of objects around the vehicle. However, dark paints on vehicles tend to absorb the radio waves and infrared signals used by such sensors. Hence, much research has been invested in the creation of multi-layer structured high technology paints … More High technology paints for enabling autonomous driving

Electrification of commercial airliner

Solar powered airplanes have been demonstrated where solar power generated by the onboard solar panels are used to power the electric motors propelling the aircraft forward. In the night, batteries storing the excess energy generated by the solar panels are used to power the electric motor. Thus, what is the barrier to the full electrification … More Electrification of commercial airliner

Conformal outsole of New Balance Fresh Foam Zante v2

Outsole of running shoes typically do not flex in response to the feet landing on the ground. However, New Balance has designed conformal outsole that flexes in response to each stride landing on the ground. Specifically, New Balance Fresh Foam Zante v2’s outsole flexes in response to the feet landing on the ground, which delivers … More Conformal outsole of New Balance Fresh Foam Zante v2

Reusing the first stage of a commercial rocket: Economic cost of retrofitting a used rocket

Rockets for satellite launches remain the most important cost item of the launch process of any commercial satellite project, given the single use nature of the rocket. Thus, commercial space launch companies such as SpaceX and Blue Origin have endeavoured to develop reusable rocket systems for reducing the cost of commercial satellite launches, and helping … More Reusing the first stage of a commercial rocket: Economic cost of retrofitting a used rocket

Challenges of recycling lithium-ion batteries

With increasing use of lithium ion batteries for personal mobile devices and computers, there is a concomitant need to plan the end of life treatment of these batteries that contain precious metals as well as toxic and flammable substances. Specifically, while lithium ion is thought to be the most important element for recover in the … More Challenges of recycling lithium-ion batteries

Aggressive frontal aerodynamic features on 2017 Formula One cars

Changes in technical regulations afford 2017 Formula 1 cars with a larger wheel base as well as a faster overall speed for enhancing overtaking opportunities, which has been a bugbear of the sport. However, current Formula 1 cars may be unbalanced in distribution of aerodynamic downforce between the front and rear of the car, given … More Aggressive frontal aerodynamic features on 2017 Formula One cars

How does the outsole design affect the performance of the midsole in shock absorption?

Focus on running shoes have always been on the midsole foam technology as well as the upper mesh design and colors. But, what is less well known is the strong influence of the outsole on the performance of the midsole foam in absorbing shock and stress. Specifically, the thread pattern of the outsole affects the … More How does the outsole design affect the performance of the midsole in shock absorption?

Strain gauges for measuring structural stability of buildings

Many buildings in earthquake prone regions of the world are vulnerable to structural damage resulting from slow creep of movement of earth. Thus, could it be possible that modern buildings incorporate strain gauges and pressure sensors for understanding the vibrations within the building due to wind effect, ground movement, or inherent oscillations of the building? … More Strain gauges for measuring structural stability of buildings

Lack of downforce at rear of hatchback could lead to oversteer

Hatchbacks are cars without a protruding rear compartment for storage. Analysis of the airflow across the car reveals that a large vortex tends to form at the rear of the car, as the airflow underneath the car attempts to merge with the one riding above it. In addition to creating drag, existence of the vortex … More Lack of downforce at rear of hatchback could lead to oversteer
