چکیده

We construct the eROSITA X-ray catalog of radio galaxies discovered by WERGS survey that is made cross-matching wide-area Subaru/HSC optical and VLA/FIRST 1.4 GHz survey. find 393 detected in 0.5--2 keV band eFEDS field covering 140~deg$^2$. Thanks to wide medium depth survey, sample contains rare most luminous above knee luminosity function, spanning 4422$. Those reside $0.4<z<3.2$, indicating they are counterparts radio-loud quasar, which missed previous quasar surveys. By combining luminosities, jet production efficiency $\eta_\mathrm{jet}$ investigated, we 14 extremely high $\eta_\mathrm{jet}\approx1$. This value might be a result 1) decreased radiation $\eta_\mathrm{rad}<0.1$ due low accretion rate for those and/or 2) boosting decline $L_\mathrm{bol}$ factor 10--100 keeping $P_\mathrm{jet}$ constant Myr, experience feedback. Finally, inferring BH masses from stellar-mass, excess emission respect estimated fundamental plane. Such cannot explained Doppler booming alone, therefore disk-jet connection eFEDS-WERGS fundamentally different conventional plane mainly covers regime.

Literature Survey - Final

Space-time coding is a powerful way to leverage spatial diversity gain and improve reliability in multiple input multiple output (MIMO) communication systems. In this paper, we examine a semi-blind adaptive time-domain equalization (TEQ) strategy in conjunction with Alamouti space-time coding to achieve channel shortening. Channel shortening is necessary when the channel response is longer than...

Survey of blindness and visual impairment in Bioko, Equatorial Guinea.

AIMS This study was designed to estimate the prevalence of blindness and its main aetiologies in Bioko, an onchocerciasis endemic zone of Equatorial Guinea. METHODS Random sampling was applied, proportionally to population distribution into urban or rural areas. All the subjects underwent a basic eye examination by trained nurses. In the presence of any ocular affection or a visual acuity of ...

Image Relighting Using Depth ECE 547 - Final Paper Daniel

This paper explores the new image processing domain involving images from depth cameras. While depth camera are a 2D array of data, the information they store is three dimensional in nature. Given a good depth image, the question now becomes what can we do with this added information. This paper explores the specific application of image relighting. Signal processing techniques of Guassian and ...
