The global elderly population is expanding at an unprecedented pace, raising significant concerns about age-related health conditions and their socioeconomic impact. In 2019, there were 703 million persons aged 65 years or over in the global population. This number is projected to double to 1.5 billion in 2050. Globally, the …
Read More »The transmission loss of the light passing through the optical fiber is a very small value of less than 0.2 dB per km with a light wavelength in the 1,550 nm band. Therefore clearest optical fibers can transmit signals more than 100 kilometers without amplification-much farther than copper wires. When …

U.S. Energy Information Administration’s latest International Energy Outlook 2017 (IEO2017) projects that world energy consumption will grow by 28% between 2015 and 2040. Most of this growth is expected to come from countries that are not in the Organization …

Quantum mechanics is the fundamental theory that describes the properties of subatomic particles, atoms, molecules, molecular assemblies and possibly beyond. Quantum technology (QT) deal with practical applications of quantum mechanical properties—especially quantum entanglement, quantum superposition and quantum tunnelling—applied to quantum systems such as atoms, ions, electrons, photons, molecules or various …

Airship is a type of lighter-than-air aircraft which can navigate through the air under its own power. They are different from Aerostats that gain their lift from large gas bags filled with a lifting gas that is less dense than the surrounding air. Historically, airships have been used in applications …

Deep Neural networks (DNN) or large virtual networks of simple information-processing units, which are loosely modeled on the anatomy of the human brain have been responsible for many exciting advances in artificial intelligence in recent years. The deep learning (DL) algorithms allow high-level abstraction from the data, and this is helpful for …

Space Tourism Market lets travelers travel in and across the Earth’s orbit for leisure, recreation, or significant business purposes. In addition, it will probably make travel …
Read More »Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic …
