This paper presents a study to develop and assess Distributed Virtual Reality (DVR) for Engineering Educa...

Direct volume rendering (DVR) is a flexible technique for visualizing and exploring scientific and biomedical volumetric data sets. Transfer functions associate field values with colors and opacities, however, for complex data are often not sufficient for encoding all relevant information. We introduce a novel visualization technique termed texture-enhanced DVR to visualize supplementary data s...

In power systems, custom power devices are used in series to avoid the voltage drop. Dynamic voltage restorer (DVR) is one of these tools. The various control techniques are available for the operating DVR. This paper is to use the dq0 technique to control DVR Series as a compensator for protection at fault furthermore, dents and bump's voltage sensitive loads to the system. The proposed contro...

The dynamic voltage restorer (DVR) is used to regulate the voltage at the load terminals from various power quality problems like sag, swell, harmonics, unbalance etc., in supply voltage. This paper presents modelling aspects of several types of Dynamic Voltage Restorer (DVR) working against various voltage sags by simulation in PSCAD/EMTDC. The reference signal for the series connected DVR is ...

abstract 0 The focus of this paper is on comparative visualization tools for scientists and also on a mechanism for communicating their results on the web. Direct volume rendering (DVR) is one of the most popular methods for visualizing 3D scientiic data including medical and molecular volumetric data. Since DVR is a relatively expensive method, much research has focused on making it faster as ...

The direct repeat (DR) region has been determined to be an important chromosomal domain for studying the evolution of Mycobacterium tuberculosis. Despite this, very little is known about microevolutionary events associated with clonal expansion and how such events influence the interpretation of both restriction fragment length polymorphism (RFLP) and spoligotype data. This study examined the s...

Power quality is one of the major concerns in the present era. The problem of voltage sags and swells and its major impact on sensitive loads are well known. To solve this problem, custom power devices are used. One of those devices is the Dynamic Vol tage Restorer (DVR), which is one of the most efficient and effective modern custom power devices used in power distribution networks. A new cont...

UNLABELLED We sought to advance methodology for studying microglial activation and putative therapeutic downregulation in response to minocycline by means of noninvasive in vivo imaging. A reproducible focal white matter lesion was used to reliably compare treatment conditions. METHODS The corpus callosum of female Sprague Dawley rats was injected with zymosan to promote microglial activation...

In this article, we present a novel decomposed vector rotation (DVR)-based recurrent neural network behavioral model for digital predistortion (DPD) of radio frequency (RF) power amplifiers (PAs) in wideband scenarios. By representing memory terms DVR with states and redesigning the piecewise modeling, propose scheme. To ensure stable operation enhanced modeling accuracy, integrate into gated l...

Now a days, the problem of voltage sags and Swells create a severe impact on sensitive loads in industries . Due to which load shedding and over voltages might occur. Several custom power devices can be used to overcome this problem. Of these power devices Dynamic Voltage Restorer (DVR) is one of the most reliable and efficient custom power devices used in power distribution network. This paper...
