Generalized Radial Flow in Synthetic Flow Systems

Groundwater, 2012
Traditional analysis methods used to determine hydraulic properties from pumping tests work well in many porous media aquifers, but they often do not work in heterogeneous and fractured‐rock aquifers, producing non‐plausible and erroneous results. The generalized radial flow model developed by Barker (1988) can reveal information about heterogeneity ...

Radial distortion correction in a vision system

Applied Optics, 2016
Accurate correction of lens distortion is the core technology in visual based measurements. Radial distortion is the most significant lens distortion in a vision system. In this paper, a radial distortion correction method named the iteration geometrical similar method is proposed.

Schäden am System Radial-Wellendichtung

2021
In diesem Kapitel werden die Schaden am System Radial-Wellendichtung vorgestellt. Vor Versuch ist es wichtig den Vorschaden an den Elementen Dichtkante und Gegenlaufflache klar zu analysieren und zu erkennen. Nach Versuch mussen die tribologischen Primarschaden an Dichtkante und Gegenlaufflache analysiert und bewertet und mit der vorgestellten ...

Loss Allocation in Radial Distribution Systems

2023
In the structured electricity distribution networks, meaningful loss allocation methods are required so that losses can be allocated without any bias to consumers connected to the distribution system. Allocating losses to the consumers is a challenging task. The main objective is to allocate losses to the consumers only based on their consumption.

Radial systems of dark globules

Astrophysics, 1986
The author gives examples of radial systems consisting of dark globules and ''elephant trunks''. Besides already known systems, which contain hot stars at their center, data are given on three radial systems of a new kind, at the center of which there are stars of spectral types later than B.

Using elevated radials in conjunction with deteriorated buried-radial ground systems

IEEE Transactions on Broadcasting, 1993
Computer-modeling exercises performed indicate that it is possible to add a group of four elevated radials to a pre-existing conventional AM-broadcast vertical monopole antenna system in order to restore performance to its original level (or better) in situations where the buried-radial ground system has been damaged.

The Y−Ӯ diagram for radial gradient systems

Applied Optics, 1988
The properties of the Y-? diagram as applied to radial gradient lens systems are developed. It is shown that the diagram consists of elliptical arcs, which are circular arcs for certain conditions. The effects of pupil and object shifts are discussed as well as the effects of scaling the pupil size.

Active Loss Allocation Systems in Radial Distribution Systems

Cogeneration & Distributed Generation Journal, 2010
ABSTRACT In the restructured power system under deregulation, proper pricing of electricity has emerged as a key issue. The cost of transmission and distribution activities needs to be allocated to the users of these networks. Among others, power losses are one of the costs to be allocated.

On smooth compactly supportée radial fuzzy system

2017 IEEE 21st International Conference on Intelligent Engineering Systems (INES), 2017
A fuzzy system with desirable properties is proposed and investigated. Membership functions used in the system are smooth functions with compact support. A suitable i-norm is designed so that the shape of employed fuzzy sets is preserved after their combination. This is called the radial property.

Contingency Assessment of Radial Distribution System

2018 IEEE 8th Power India International Conference (PIICON), 2018
The purpose of the investigation presented in this paper is to obtain the optimal restructure of radial distribution system under the impact of contingencies, with and without the scope of distributed generation. Firstly, solution to occurrence of contingency is proposed by finding out the best switching sequence of a specified number of tie lines and ...
