This paper proposes improvements to the binary grey-wolf optimizer (BGWO) solve feature selection (FS) problem associated with high data dimensionality, irrelevant, noisy, and redundant that will then allow machine learning algorithms attain better classification/clustering accuracy in less training time.We propose three variants of BGWO addition standard variant, applying different transfer fu...

Metal bending tube is widely used in industry while its forming defects extremely affect the quality. Among all defects, bending-inside wrinkling caused by non-uniform compressive stress a zero-tolerated defect, particularly when for transportation. However, current detection approach, suffering from lack of insight into mechanism, normally posteriori. To obtain priori condition certain go-to-b...

The reintroduction of the gray wolf into the Northern Rocky Mountains has created many difficult management issues; ranchers fear for their livestock, hunters worry about game populations, ecologists and biologists support the reintroduction, and resource management agencies are caught in the middle. To date (2000), the one hundred plus wolves in the Yellowstone National Park area and approxima...

Named entity recognition (NER) is a subfield of natural language processing (NLP). It able to identify proper nouns, such as person names, locations, and organizations, has been widely used in various tasks. NER can be practical extracting information from social media data. However, the unstructured noisy nature (such grammatical errors typos) causes new challenges for NER, especially low-reso...

In this article, a multi-objective planning is demonstrated for reactive power compensation in radial distribution networks with wind generation via unified power quality conditioner (UPQC). UPQC model, based on phase angle control (PAC), is used. In presented method, optimal locating of UPQC-PAC is done by simultaneous minimizing of objective functions such as: grid power loss, percentage of n...

In this work, the adsorption mechanism of phenol on activated carbon from aqueous solutions was investigated. Batch experiments were performed as a function adsorbent rate, solution temperature, initial concentration, stirring speed, and pH. The optimal operating condition were: mass/volume ratio 0.6 g.L?1, temperature 20 °C speed 300 rpm. equilibrium data for analyzed by Langmuir, Freundlich, ...

Some civil engineering-based infrastructures are planned for the Structural Health Monitoring (SHM) system based on their importance. Identifiction and detecting damage automatically at the right time are one of the major objectives this system faces. One of the methods to meet this objective is model updating whit use of optimization algorithms in structures.This paper is aimed to evaluate the...
