The LOFAR Two-metre Sky Survey (LoTSS) is a deep 120-168 MHz imaging survey that will eventually cover the entire Northern sky. Each of 3170 pointings be observed for 8 hrs, which, at most declinations, sufficient to produce ~5arcsec resolution images with sensitivity ~0.1mJy/beam and accomplish main scientific aims which are explore formation evolution massive black holes, galaxies, clusters galaxies large-scale structure. Due compact core long baselines LOFAR, provide excellent both highly...
Abstract The Evolutionary Map of the Universe (EMU) is a proposed radio continuum survey Southern Hemisphere up to declination + 30°, with Australian Square Kilometre Array Pathfinder (ASKAP). EMU will use an automated source identification and measurement approach that demonstrably optimal, maximise reliability robustness resulting catalogues. As step toward this goal we conducted “Data Challenge” test variety finders on simulated images. aim quantify accuracy limitations existing finding...
We present LOFAR Low Band observations of the Bootes and 3C295 fields. Our images made at 34, 46, 62 MHz reach noise levels 12, 8, 5 mJy beam$^{-1}$, making them deepest ever obtained in this frequency range. In total, we detect between 300 400 sources each these images, covering an area 17 to 52 deg$^{2}$. From derive Euclidean-normalized differential source counts. The counts agree with previous GMRT 153 VLA 74 counts, scaling a spectral index $-0.7$. find that $-0.5$ is required match up...
The objective of this work was to design and build a wind turbine which can be used power small street lights. Considering the typical speeds in Abu Dhabi, UAE ease construction, chosen Sea Hawk from vertical axis category. A three phase AC generator for its availability over DC motors within region. 12V battery storage charge controller controlling flow into rotation when is fully charged. blades were made foam board according NACA 0018 airfoil shape with chord length 15cm. connecting shaft...

Venus was observed at frequencies of 1297.67 MHz (23 cm), 607.67 (49 cm) and 233.67 (1.28 m) with the Giant Metrewave Radio Telescope (GMRT) during period 25th July 6th September 2015 when it close to its inferior conjunction. Values brightness temperature (Tb) from these observations were derived as 622{\pm}43 K, 554{\pm}38 K for frequencies, respectively, are in agreement previous observations. The attempt derive Tb affirms an upper limit 321 which is significantly lower than previously...
Physicians often seek scientific evidence regarding how to best care for their patients, while making clinical decisions These are available in the form of published medical articles, reports and trials. Considering volume already existing literature pace at which research is growing, getting most relevant information will be a tedious task. In this paper, we describe an empirical approach fetch articles from PubMed (about 733,328 45.2 gigabytes) collection, based on given query. Our IR...
Abstract Radiometric observations of Venus have revealed a monotonic decrease brightness temperature ( T b ) in the decimeter wavelength regime. Such has also been independently reported by using interferometric radio‐telescopes, like Very Large Array (VLA) USA and Giant Metrewave Radio Telescope (GMRT) India. In this work, we carried out microwave radiative transfer (RT) simulations thermal emission from Venusian surface at wavelengths to examine role subsurface properties regolith...
The radio-thermal emission from Venus as observed by ground-based interferometric radio-telescopes shows a significant spectral variation, with gradual increase in brightness temperature 1 mm to 6 cm and decrease thereafter at higher wavelengths. first time GMRT observations beyond 70 wavelength also reconfirm this decreasing trend T <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">b</sub> the [7].
