Modelling is the process of representing a model (e.g., physical, mathematical, or logical representation of a system, entity, phenomenon, or process) which includes its construction and working. This model is similar to a real system, which helps the analyst predict the effect of changes to the system. Simulation of a …

Nanopowders
Nanopowders are defined as powdered materials with individual particles having sizes under 100 nanometers. International Standardisation Organisation (ISO) defines nanopowder is a solid powder-like substance of artificial origin that contains nanoobjects, aggregates or agglomerates of nanoobjects or a combination thereof; 2) an assembly of nanoparticles; 3) a powder, all particles …

Modern microelectronic semiconductors and integrated circuits provide remarkable computational and memory capabilities but lack the capability to interface with the physical world directly. MEMS (MicroElectroMechanical Systems) and the even smaller NEMS (Nano ElectroMechanical Systems) integrate sensors and actuators on microelectronic circuitry and enabling these products, awareness of the surroundings in …

Flat-panel display technology is exploding on several fronts as more screens are required for more devices. CRT still works well for screen sizes up to 40 inches. But if you want a larger screen, a flat panel TV, widescreen model or HDTV compatibility, you’ll have to choose from several types …

Remote sensing is the science of acquiring information about the Earth’s surface without actually being in contact with it. This is done by sensing and recording reflected or emitted energy and processing, analyzing, and applying that information. Some examples of remote sensing are special cameras on satellites and airplanes taking …

Space is becoming more dynamic than ever with mega-constellations, multi-orbit satellites, and software-defined payloads. The world’s demand for broadband connectivity has created a new generation of high-throughput satellites in geosynchronous Earth orbit (GEO), medium Earth orbit (MEO), and now low Earth orbit (LEO). In the future, 5G networks will …

Carbon nanotubes (CNTs) are hollow cylindrical tubes formed by rolling a sheet of carbon atoms arranged in a hexagonal ring, as in a sheet of graphite, either in monolayer (single-walled nanotube, SWCNT) or multilayer (multi-walled nanotube, MWCNT) form. CNTs exhibit different electronic properties based on the way these graphene …

The US and Israel are universally recognized leaders in the development and use of unmanned aerial vehicles (UAVs) or drones. Thousands of American and Israeli UAVs are operating across the world daily. China is already world’s largest producer of UAVs and is working on taking on a greater share in …

The APM Body of Knowledge 6th edition defines handover as: “The point in the life cycle where deliverables are handed over to the sponsor and users.” . It might also be the end of the defects and liability period (essentially the first year’s warranty period of a building). It could …

Substantially more spectrum bandwidth is available at the Ka band than at the Ku band and other lower frequencies. For example, Ku band allocation is around 2GHz for uplink and 1.3GHz for downlink with actual contiguous bandwidth allocation of less than 0.5GHz per satellite. In comparison, the Ka band SATCOM …
