The Connected Components of two GaugeGroups
نویسنده
چکیده
We calculate the connected components of the Gauge group of a Z/2 equivariant oriented 3-plane bundle and a related 4-plane bundle over the antipodal 3-sphere. This suggests that an obstruction which has earlier been claimed to vanish, does not necessarily do so.

Optimal Estimation of Harmonic Components Using ISFLA
In this paper a novel method based on evolutionary algorithms is presented to estimate the harmonic components. In general, the optimization of the harmonic estimation process is a multi-component problem, in which evaluation of the phase and harmonic frequency is the nonlinear part of the problem and is solved based on the mathematical and evolutionary methods; while estimation of amplitude of...
متن کاملکنترل کننده پیشفاز-پسفاز مقاوم برای تولیدات پراکنده در شرایط جزیره‌ای
Distributed generations that are connected to the network via a converter, employ dq current control method to control their active and reactive power components in grid-connected mode. In this paper a simple lead-lag control strategy is proposed for a distributed generation (DG) unit in island mode. When it is connected to the utility grid, the DG is controlled by a conventional dq-current con...
متن کاملA Survey On the Vulnerability Parameters of Networks
The analysis of vulnerability in networks generally involves some questions about how the underlying graph is connected. One is naturally interested in studying the types of disruption in the network that maybe caused by failures of certain links or nodes. In terms of a graph, the concept of connectedness is used in dierent forms to study many of the measures of vulnerability. When certain vert...

متن کاملPersian Printed Document Analysis and Page Segmentation
This paper presents, a hybrid method, low-resolution and high-resolution, for Persian page segmentation. In the low-resolution page segmentation, a pyramidal image structure is constructed for multiscale analysis and segments document image to a set of regions. By high-resolution page segmentation, by connected components analysis, each region is segmented to homogeneous regions and identifyi...
