Given X, Y ∈ Rn×m we introduce the following notion of matrix majorization, called weak matrix majorization, X w Y if there exists a row-stochastic matrix A ∈ Rn×n such that AX = Y, and consider the relations between this concept, strong majorization ( s ) and directional majorization ( ). It is verified that s⇒ ⇒ w , but none of the reciprocal implications is true. Nevertheless, we study the i...

In this paper, two H-plane horn antennae are designed using groove and ridge gap waveguide (GGW RGW) techniques. the proposed structures, is partially filled with a dielectric to control amplitude phase distribution across antenna aperture so that very low side lobe level (SLL) can be achieved. Two sample simulated for frequency range from 12 16 GHz, prototypes fabricated. The fabricated show q...

Variances and covariances were estimated for birth weight (BWT), weaning weight (WW), yearling gain (YG), yearling weight (YW), yearling height (YH), relative growth from birth to weaning (RGW) and weaning to yearling (RGY), and mature weight (MW). Field records on 572,446 Polled Hereford cattle were analyzed. Because multiple dam weights were collected on a cow the MW used in the analysis was ...

The TISPAN group from ETSI is currently working on the specification a Next Generation Network (NGN), based on the IP Multimedia Subsystem (IMS) as the service control architecture. This NGN provide a extensible platform that supports the delivering of next generation multimedia services with QoS requirements over multiple access network technologies. Nevertheless, the QoS solutions developed b...

Aiming at overcoming the disadvantages of the algorithm proposed by White, R. G. (RGW) and making it applicable for PolSAR data classification, a novel edge-detection algorithm based on segmentation for Polarimetric SAR images is proposed in this paper. As one of the famous algorithms based on objected-oriented segmentation, RGW has been used extensively in image segmentation. However, it also ...

Internet access has been, until now, the main driver for the generalization of broadband connections in the residential market. Simple IP based services like email and web browsing were, during many years, the typical services provided to residential customers. Today the telecommunications market is changing and operators are looking for ways to provide, through those same IP broadband connecti...

In this paper, we improve the calculation of the relic gravitational waves (RGW) in two aspects: First, we investigate the transfer function after considering the redshift-suppression effect, the accelerating expansion effect, the damping effect of free-streaming relativistic particles, and the damping effect of cosmic phase transition, and give a simple approximate analytic expression, which c...

We generalize the classical notion of majorization in Rn to a majorization order for functions defined on a partially ordered set P . In this generalization we use inequalities for partial sums associated with ideals in P . Basic properties are established, including connections to classical majorization. Moreover, we investigate transfers (given by doubly stochastic matrices), complexity issue...

We introduce a partial order, variance majorization, on R, which is analogous to the majorization order. A new class of monotonicity inequalities, based on variance majorization and analogous to Schur convexity, is developed.
