Component-by-component construction of shifted Halton sequences

open access: yes, 2015
We study quasi-Monte Carlo integration in a weighted anchored Sobolev space. As the underlying integration nodes we consider Halton sequences in prime bases $\boldsymbol{p}=(p_1,\ldots,p_s)$ which are shifted with a $\boldsymbol{p}$-adic shift based on $\boldsymbol{p}$-adic arithmetic. The error is studied in the worst-case setting.

MMC-SST input-level control strategy considering power quality optimization

open access: yes电力工程技术, 2022
The surge of negative sequence component of current affects the waveform quality of grid side current and endangers the normal operation of the system when the three-phase voltage of solid state transformer (SST) in the distribution network is unbalanced

Spatiotemporal Barcodes for Image Sequence Analysis [PDF]

open access: yes, 2015
Taking as input a time-varying sequence of two-dimensional (2D) binary images, we develop an algorithm for computing a spatiotemporal 0–barcode encoding lifetime of connected components on the image sequence over time.

Describing Component Collaboration Using Goal Sequences [PDF]

open access: yes, 2008
Services are normally not performed by a single component, but result from the collaboration of several distributed components. Their precise specification and validation require complex models, where the intention of the service is easily lost in the detail.

Component trees for image sequences and streams [PDF]

open access: yesPattern Recognition Letters, 2020
Abstract Morphological hierarchies now form a well-established framework for (still) image modeling and processing. However, their extension to time-related data remains largely unexplored. In this paper, we address such a topic and show how to analyze image sequences with tree-based representations.

Installation locations of surge arresters on double-circuit transmission lines

open access: yesZhejiang dianli
The connected series-compensated capacitors alter the sequence network impedance of transmission lines and the distribution of sequence currents during faults.

Prediction of Dissolved Gas Concentration in Transformer Oil Based on Hybrid Mode Decomposition and LSTM-CNN

open access: yesZhongguo dianli, 2023
Predicting the concentration of dissolved gas in oil can help to know in advance the operation trend of transformers. A prediction method is thus proposed based on hybrid mode decomposition and LSTM-CNN network to achieve accurate gas concentration ...

Motion connected operators for image sequences [PDF]

open access: yes, 1996
This paper deals with motion-oriented connected operators. These operators eliminate from an original sequence the components that do not undergo a specific motion (defined as a filtering parameter).

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...
