We present deep spectroscopic data for a 24-object subsample of our full 41-object z ∼ 0.5 radio galaxy sample in order to investigate the evolution of the Fundamental Plane of radio galaxies.We find that the low-luminosity, FRI-type, radio galaxies in our sample are consistent with the local Fundamental Plane of radio galaxies defined by Bettoni et al. when corrected for simple passive evoluti...

In this paper a novel robust radio-interferometric object tracking method is proposed. The system contains fixed infrastructure transmitter nodes generating interference signals, the phases of which are measured by the tracked receivers and other fixed infrastructure nodes. From the measured phase values a confidence map is computed, which is used to generate the track of the moving receivers. ...

The primary reason for diversity of distributed storage systems is that no single design for a distributed storage system is cost-optimal for meeting the latency and throughput SLOs in all possible workloads. In other words, a distributed object store that satisfies the SLOs for a particular workload at minimum cost (in comparison to other object stores) will incur higher costs than alternate s...

introduction: foreign bodies in the upper aerodigestive tract often get lost following inappropriate attempts at removal. children may present late with localized infection, posing a challenge to the otolaryngologists in a referral set-up in diagnosing and retrieving such foreign bodies.   case report: a two-year-old boy presented with refractory purulent rhinorrhea and intermittent low-grade f...

We have made a radio and optical study of the radio source PKS 0241+011 associated with a quasar at z = 1.40. In earlier radio maps this source appears as a large triple radio source with an angular extent of 400 arcsec (2.4h −1 Mpc; H 0 = 100h km s −1 Mpc −1 , q 0 = 0.0). If the triple radio structure seen in radio maps represents a single object, PKS 0241+011 would be the largest radio quasar...

Aims. We investigate the spectral characteristics of 51 candidate High Frequency Peakers (HFPs), from the “bright” HFP sample, in order to determine the nature of each object, and to obtain a smaller sample of genuine young radio sources. Methods. Simultaneous multi-frequency VLA observations carried out at various epochs have been used to detect flux density and spectral shape variability in o...

This paper describes a personal view of the discovery of radio jets in celestial radio sources. The existence of narrow, collimated optical features in distant objects has been known about since the early 20th century; however, the advent of radio astronomy in the 1940s and 1950s revealed the existence of a large number of discrete radio sources. The realization that many of these objects were ...

In the early deployment of electric toll collecting (ETC) system, multipath interference has caused the malfunction of the system. Therefore, radio absorbers are installed in the toll gate to suppress the scattering. This paper presents a novel radio propagation measurement system to identify the individual scattering object and the power intensity of the ETC gate in real time.

data types: Abstraction is the act of representing something without including background or inessential detail [p.10 Gra94]. An abstract data type is an abstraction that encapsulates the components of a set of objects. Abstract data types are defined by the programmer rather than being specified in the particular programming language. The abstract data type defines both attributes and methods ...
