Anti drone systems are used to detect and/or intercept unwanted drones and unmanned aerial vehicles (UAVs). Hostile drones may be used to deploy explosives, smuggle contraband or gather intelligence on sensitive assets, and the proliferation of low-cost UAVs has led to an increase in incidents. Anti drone technology is deployed to protect areas such as airports, critical infrastructure, large public… Read more →
Railway sleepers, also called railroad ties, railway ties or crossties, are an important railway component. Generally, the rail sleeper is always laying between two rail tracks to keep the correct space of the gauge. In recent time, concrete sleepers are widely used, especially in Europe and Asia. And in the UK, steel ties are common. Besides, plastic composite ties are… Read more →
Most often used in foggy conditions, is a device that uses sound to warn vehicles of hazards. Generally, marine transport is using the term. When lighthouses are obscured the foghorn provides an audible warning of any dangers to ships. Robert Foulis created the first automated steam-powered foghorn. After hearing his daughter play piano in the fog, he realized the lower… Read more →
Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbours, and other water bodies. It is a routine necessity in waterways around the world because sedimentation, the natural process of sand and silt washing downstream gradually fills channels and harbours. Dredging often is focused on maintaining or increasing the depth of navigation channels, anchorages, or… Read more →
A pontoon bridge, also known as a floating bridge, uses floats or shallow-draft boats to support a continuous deck for pedestrian and vehicle travel. The buoyancy of the supports limits the maximum load they can carry. Most pontoon bridges are temporary, used in wartime and civil emergencies. Floating bridges are made of large water-tight concrete pontoons connected rigidly end-to-end, upon… Read more →
When a spacecraft is launched into orbit, it should end up spinning around the Earth quickly enough not to be pulled back in by the Earth’s gravity. The huge rockets used in launching a spaceship help this to happen by giving a huge amount of thrust, enough to achieve escape velocity. However, the spin of the Earth itself can help… Read more →
Geofencing is a location-based service in which a creator of an app or other platform/software uses GPS, RFID, Wi-Fi or cellular data to send/trigger messages like SMS, Email or In-App/App-based notifications (pre-programmed action) when mobile devices that enter, exit, or remain parked in the geographical location. You can select and mark off a geographical area from a map and set… Read more →
High-G training is done by aviators and astronauts who are subject to high levels of acceleration (‘G’). It is designed to prevent a g-induced loss of consciousness (G-LOC), a situation when the action of g-forces moves the blood away from the brain to the extent that consciousness is lost. Incidents of acceleration-induced loss of consciousness have caused fatal accidents in… Read more →
Bio-electrical Impedance Analysis or Bioimpedance Analysis (BIA) is a method of assessing your body composition: the measurement of body fat in relation to lean body mass. It is an integral part of a health and nutrition assessment. BIA allows for early detection of an improper balance in your body composition, which fosters earlier intervention and prevention. BIA also provides a… Read more →
As a fighter pilot, one of the most common questions they get is: How do you go to the bathroom in an F-16 or F-35? Let me start off by describing the cockpit. Now, typically in training, flights are less than an hour and a half. As long as you don’t drink too much coffee before a flight, it’s generally… Read more →
