Optimization of assembly sequence of building components based on simulated annealing genetic algorithm

open access: yesAlexandria Engineering Journal, 2023
A large number of prefabricated components are composed of different types of houses. The on-site assembly sequence of components is also the key link of the construction organization of the project. The assembly sequence obtained by manual experience is

Principal components analysis of protein sequence clusters [PDF]

open access: yesJournal of Structural and Functional Genomics, 2014
Sequence analysis of large protein families can produce sub-clusters even within the same family. In some cases, it is of interest to know precisely which amino acid position variations are most responsible for driving separation into sub-clusters. In large protein families composed of large proteins, it can be quite challenging to assign the relative ...

Practical calculation of asymmetric short circuit current of DFIG connected to distribution network [PDF]

open access: yesE3S Web of Conferences, 2020
In view of the existing complex analytic calculations of DFIG short-circuit current are hardly applied in engineering projects, a practical calculation of asymmetric short-circuit current of DFIG is proposed.

Sequence, a BioJS component for visualising sequences [PDF]

open access: yesF1000Research, 2014
Summary: Sequences are probably the most common piece of information in sites providing biological data resources, particularly those related to genes and proteins. Multiple visual representations of the same sequence can be found across those sites.

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.

A Negative Sequence Current Phasor Compensation Technique for the Accurate Detection of Stator Shorted Turn Faults in Induction Motors

open access: yesEnergies, 2022
Stator faults are the most critical faults in induction motors as they develop quickly hence requiring fast online diagnostic methods. A number of online condition monitoring techniques are proposed in the literature to respond to such faults, including ...

Graph Database and Matrix-Based Intelligent Generation of the Assembly Sequence of Prefabricated Building Components

open access: yesApplied Sciences, 2023
The assembly of prefabricated components is a critical process in prefabricated building construction, influencing both progress and accuracy. However, the assembly sequence planning and optimization (ASPO) of prefabricated components have yet to receive
