To modernize the management of sensitive nuclear materials, Argonne National Laboratory has developed the ARG-US radio frequency identification (RFID) system for the Packaging Certification Program of the U.S. Department of Energy (DOE), Office of Packaging and Transportation. The system consists of battery-powered RFID tags, a reader network, an application software suite, secured database ser...
GRIPS (Generic Radio based Indoor Positioning System) is an indoor radio signal strength based positioning system. In order to track, locate and inform mobile users, GRIPS’ devices participate in WLAN/Bluetooth ad-hoc or access-point based wireless networks. Apart from its ability to track passive devices, it is possible to deploy the system in a spontaneous adhoc manner. With the help of cheap...
The Iranian Light Source Facility (ILSF) project is the first large scale accelerator facility which is currently under planning in Iran. On the basis of the present design, circumference of the 3 GeV storage ring is 528 m. Beam current and natural beam emittance are 400 mA and 0.477 nm.rad, respectively. Some prototype accelerator components such as high power solid state radio frequency ampli...
PSR J1023+0038 is an exceptional system for understanding how slowly rotating neutron stars are spun up to millisecond rotational periods through accretion from a companion star. Observed as a radio pulsar from 2007–2013, optical data showed that the system had an accretion disk in 2000/2001. Starting at the end of 2013 June, the radio pulsar has become undetectable, suggesting a return to the ...
In order to prepare antibacterial and radio-opaque dental resin, a methacrylate monomer named 2-Dimethyl-2-dodecyl-1-methacryloxyethyl ammonium iodine (DDMAI) with both antibacterial and radio-opaque activities was added into a 2,2-bis[4-(2-hydroxy-3-methacryloyloxypropyl)-phenyl]propane (Bis-GMA)/methyl methacrylate (MMA) dental resin system. Degree of conversion (DC), flexural strength (FS) a...
Radio over fiber (RoF) is one of the primary technologies for the provision of future broadband networks. This work is focused to the implementation of cost effective radio over multimode system (Ro-MMF) for long haul communication. A 10 Gbps data along with 10 GHz radio signal is transmitted over multimode fiber link of 40 km. Moreover, the results are also reported for proposed Ro-MMF system ...
Audio watermarking (AW) technology is considered for stealthy information embedding directly into audio signal. Inherent in analog radiotelephone channel interferences against watermarks are analyzed. Robust encoding/decoding algorithms are presented and appropriate project of AW system named as Automatic Radio Telephone Identification System (ARTIS) is proposed. Experiment...
The standardisation work of GSM-based systems has its roots in the 1980s, when a standardisation body ‘Groupe Special Mobile’ (GSM)1 was created within the Conference Europeenne des Postes et Telecommunications (CEPT), whose task was to develop a unique digital radio communication system for Europe, at 900 MHz. Since the early days of GSM development, the system has experienced extensive modifi...
The wireless market is developing very fast today with a steadily increasing number of users all around the world. An increasing number of users and the constant need for higher and higher data rates have led to an increasing number of emerging wireless communication standards. As a result there is a huge demand for flexible and low-cost radio architectures for portable applications. Modern rad...
We present radio, optical, near-infrared and spectroscopic observations of the source B0827+525. We consider this source as the best candidate from the Cosmic Lens AllSky Survey (CLASS) for a ‘dark-lens’ system or binary radioloud quasar. The system consists of two radio components with somewhat different spectral indices, separated by 2.815 arcsec. VLBA observations show that each component ha...
