We present the results of 5 GHz VLBI observations of a compact steep spectrum source 3C 138. The data are consistent with the western end being the location of the central activity. The observed offset between different frequencies in the central region of 3C 138 can be accounted for by a frequency dependent shift of the synchrotron self-absorbed core. Our new measurements confirm the existence...

As an alternative to ski jumps, deflectors can be implemented on spillways to generate free jets. They guide, up to a certain limit, the jet to an achieved location onto the plunge pool surface, and furthermore enhance the process of jet disintegration. The present research addresses the following aspects, derived from physical model tests: (1) length and shape of the jet black-water core and f...

Active flow control methods based on dielectric barrier discharge plasma actuators can be used to increase the efficiency of combustion systems. In this study, influence location bluff body in a non-premixed burner non-reactive field fuel and oxidizer is investigated numerically. Flow properties spatial mixing deficiency (SMD) are calculated evaluate actuator's reactants' inside burner. The res...

We have detected an optical jet in the BL Lac object 3C 371 that coincides with the radio jet in this object in the central few kpc. The most notable feature is a bright optical knot 3 ′′ (4 kpc) from the nucleus that occurs at the location where the jet apparently changes its direction by ∼ 30 •. The radio, near-infrared and optical observations of this knot are consistent with a single power-...

We present a new user interface technique for the visualization and playback of long media streams decorated with significant events. Our Multi-Scale Timeline Slider allows users to precisely focus on a specific location in a very long media stream or set of streams based on significant events while also retaining the stream’s entire context.

GGD 34 is a protostellar jet with wiggles which are accompanied by “sine-like” variations in the radial velocity of the emitting material by as much as 60 km s−1. Thus GGD 34 is an interesting object to understand the physical mechanisms involved in the generation of wiggles in protostellar jets. In this work we present high resolution images obtained with the Canada-France-Hawaii Telescope (CF...

We present a real-time multiple human tracking system for a humanoid with a pair of microphones and a pair of cameras. The key idea for robust recognition and scalability of multi-modality is the hierarchical integration of multiple sensory information. First, sound direction by auditory localization module, speaker ID by spear identi cation module, face location, face ID, and object location b...

This paper presents a comparison between Radio Tomographic Imaging (RTI) and Device-free Passive (DfP) tracking in standard WiFi networks. We show that for typical WiFi deployments, tracking methods are able to extract location information from a limited number of streams while imaging methods fail to produce meaningful images. On the other hand, we show that when the number of streams increase...
