RADIO FREQUENCY IDENTIFICATION IN CYBER-PHYSICAL SYSTEMS [PDF]

Measuring Equipment and Metrology, 2021
Automated systems that are part of cyber-physical systems provide distribution of goods or prefabricated components, as well as their documenting and automatic tracking in real-time. Workpieces are marked with RFID transponders. RFID antennas allow contactless reading and/or recording of information, RFID electronics process and transmit it to the ...

Student perspectives in quantum physics [PDF]

, 2008
Introductory courses in classical physics are promoting in students a realist perspective, made up in part by the belief that all physical properties of a system can be simultaneously specified, and thus determined at all future times. Such a perspective

Physics of nonthermal radio sources [PDF]

Physics Today, 1963
The fundamental observational problem in radio-astronomical investigations of discrete sources is the determination of the precise positions and spectra of these objects, as well as measurement of the brightness distributions of those sources large enough to be resolved by existing equipment.
