Backscattering is a form of wireless transmission based on modulated reflection of external RF signals. Whereas conventional radios generate their own signals, backscatter radios transmit data by making tiny changes to reflected signals. This approach requires a minimal number of active components, promising simple low-cost battery-free operations.   Since the source …

Artificial intelligence is a branch of computer science dealing with the simulation of intelligent behavior in computers. A computer system able to perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and translation between languages. Machine learning is a subset of AI.  AI has a …

Quantum computers promise the potential to tackle problems that conventional computers can’t handle by leveraging a phenomenon of quantum physics that allows qubits to exist in multiple states simultaneously. As a result, qubits can conduct a large number of calculations at the same time — dramatically speeding up complex problem-solving. …

The amount of information trafficking internet nowadays is enormous and will increase further in the near future. It can be expected that in the next decennia the current technologies to store and process data will no longer suffice and that other strategies to handle information have to be developed. One …

The general definition of AI is the capability of a computer system to perform tasks that normally require human intelligence, such as visual perception, speech recognition and decision-making. Machine Learning (ML) is a subfield of Artificial Intelligence which attempts to endow computers with the capacity of learning from data, so that …

The principle of timekeeping has been to count the repetitions or oscillations of repeating natural phenomena such as rotation of earth or movement of stars. Over the millennia a myriad of devices has been invented for timekeeping including pendulum or crystals, each with a period far shorter than the daily …

UAVs are Aircrafts that are piloted remotely by some person who is at a different place. These UAVs of various sizes and shapes can fly continuously for more than 24 hours and some of them can only fly for less than 30 minutes. Some UAVs have wings of several meters …

Nanotechnology deals with the understanding, control, and manufacture of matter in the nanoscale regime, usually between 1 nm to 100 nm, and exploiting them for a useful application. At this length scale, unique properties and phenomena arise as a result of increased surface-to-volume ratio and dominance of quantum mechanical effects. …
