We produce and analyse u-band (λ ≈ 355 nm) luminosity functions for the red and blue populations of galaxies using data from the Sloan Digital Sky Survey (SDSS) u-band Galaxy Survey (uGS) and Deep Evolutionary Exploratory Probe 2 (DEEP2) survey. From a spectroscopic sample of 41 575 SDSS uGS galaxies and 24 561 DEEP2 galaxies, we produce colour magnitude diagrams and make use of the colour bimo...

Combiner and Stacked Generalization are two very similar meta-learning methods that combine predictions of multiple classiiers to improve accuracy of any single classiier. Both methods form a meta-level classiier from meta-data that are predictions of multiple classiiers on the same data items. The diierence between these two approaches lies in the way meta-data is formed. In this paper, we com...

Conventionally, diplexers are designed by connecting two filters of different frequencies using a transmission T-line junction which acts as distribution network serving the individual filters. Here, novel diplexer has been proposed and to utilize directly coupled resonator network. The is square open-loop resonators same resonant frequency 1.95 GHz. Coupling achieved ?/4 line couple them. This...

Ultra Wideband (UWB) is a new emerging and promising technology as it can accommodate higher data over a large bandwidth. we proposed a Printed Square-shape UWB Antenna With Dual Band-Notched Characteristics. A simple square patch antenna has been fed through a 50 Ω microstrip feedline .A rectangular notch has been etched on the ground plane to reject the interference of WIMAX Band (3GHZ-4.7GHZ...

Abstract— The paper presents the design and performance measures of a printed stepped patch monopole antenna with semi-elliptical ground plane and band notch for ultra wideband applications. The proposed antenna operates in the frequency range 3.15 ~ 12.2 GHz with average gain of 4.27 dBi. Inverted U shaped slot is introduced in the feed line for WLAN band rejection and the rejection band range...
