background: ultraviolet (uv) radiation is divided into three regions: uva, uvb, and uvc. both the quality and quantity of solar uv radiation vary with various factors including the elevation of the sun above the horizon, as well as absorption and scattering of uv photons by molecules in the atmosphere, notably ozone and clouds. it is clear that whereas a moderate amount of uv exposure is benefi...

Knowledge of the spatial and temporal distribution heat flux is great interest for quantification sources. In this work, we describe development a new ultra-broadband contactless imaging power meter based on electromagnetic to infrared technology. This sensor mathematical processing images enable reconstruction both amplitude distributions through wide spectral range The full modeling thermocon...

This paper presents measurements and analysis of broadband Internet access service networks using a highspeed IP meter with a GPS (Global Positioning System) timestamp component. The authors performed measurements of traffic in a commercial IPv6 access service on ADSL (Asymmetrical Digital Subscriber Line) as a typical broadband access service network. This paper describes the measurement confi...

We consider enhancing the sensitivity of future gravitational-wave detectors by adding optical filters inside the signal-recycling cavity—an intracavity filtering scheme, which coherently feeds the sideband signal back to the interferometer with a proper frequency-dependent phase. We study three cases of such a scheme with different motivations: (i) the case of backaction noise evasion, trying ...

Conventional applications of matched-field processing (MFP) use large aperture vertical arrays and low frequency signals. It is well known that MFP’s sensitivity to environmental mismatch is proportional to frequency. Thus, real-world application of MFP to mid-frequency signals, e.g., 800 3000 Hz, is generally regarded a very difficult problem. Using small aperture vertical arrays can also comp...

In recent years the quantity and diversity of Internet-enabled consumer devices in the home have increased significantly. These trends complicate device usability and home resource management and have implications for crowdsourced approaches to broadband characterization. The UPnP protocol has emerged as an open standard for device and service discovery to simplify device usability and resource...

We conducted a multi-wavelength campaign in September-October, 2002, to observe SS 433. We used 45 meter sized 30 dishes of Giant Meter Radio Telescope (GMRT) for radio observation, 1.2 meter Physical Research Laboratory Infra-red telescope at Mt Abu for IR, 1 meter Telescope at the State Observatory, Nainital for Optical photometry, 2.3 meter optical telescope at the Vainu Bappu observatory fo...
