    Nondestructive Testing of Bridge Stay Cable Surface Defects Based on Computer Vision

    Fengyu Xu1,2, Masoud Kalantari3, Bangjian Li2, Xingsong Wang2,*

    CMC-Computers, Materials & Continua, Vol.75, No.1, pp. 2209-2226, 2023, DOI:10.32604/cmc.2023.027102

    Abstract The automatically defect detection method using vision inspection is a promising direction. In this paper, an efficient defect detection method for detecting surface damage to cables on a cable-stayed bridge automatically is developed. A mechanism design method for the protective layer of cables of a bridge based on vision inspection and diameter measurement is proposed by combining computer vision and diameter measurement techniques. A detection system for the surface damages of cables is de-signed. Images of cable surfaces are then enhanced and subjected to threshold segmentation by utilizing the improved local grey contrast enhancement method and the improved maximum correlation… More >

    Genetic Analysis of Variants of the MYH6 Gene Promoter in Congenital Atrial Septal Defects

    Ji-Yang Zuo1,2, Huan-Xin Chen1,2, Zhi-Gang Liu1,2, Qin Yang1,2, Guo-Wei He1,2,*

    Congenital Heart Disease, Vol.18, No.1, pp. 7-21, 2023, DOI:10.32604/chd.2022.025451

    Abstract Background: Atrial septal defect (ASD) is one of the common congenital heart diseases. The MYH6 gene has a critical role in cardiac development but the role of MYH6 promoter variants in patients with ASD has not been explored. Methods: In 613 subjects including 320 ASD patients, we investigated the MYH6 gene promoter variants and verified the effect on gene expression by using cellular functional experiments and bioinformatics analysis. Results: Eleven variants were identified in the MYH6 gene promoter, of which four variants were found only in ASD patients, and two variants (g.3434G>C and g.4524C>T) were identified for the first time.… More > Graphic Abstract

    Congenital Heart Disease, Vol.17, No.6, pp. 687-695, 2022, DOI:10.32604/chd.2022.024333

    Abstract Background: Interventricular septal hematoma is a rare complication after congenital cardiac repair. The management varies according to the literature. We present our experience with this rare complication. Methods: Echocardiography database were reviewed with the term ‘‘hematoma’’ or “hypoechoic mass” for patients who underwent congenital heart surgery from January 2018 to December 2021 at our institution to identify potential interventricular septal hematoma cases. Relevant data of the patients identified were collected. Focus was put on the presentation, management, outcomes according to patent medical charts and serial echocardiographic report data. Results: In total, there were 5 patients included. The mean age and… More > Graphic Abstract

    Congenital Heart Disease, Vol.17, No.6, pp. 653-673, 2022, DOI:10.32604/chd.2022.021580

    Abstract Background: Over 400 genes contribute to the development of congenital heart disease (CHD). Additionally, multisystemic manifestations accompanying syndromic CHD pose a higher risk of genetic diseases. This study investigated the diagnostic yield of whole-exome sequencing (WES) in patients with sporadic syndromic CHD and the phenotypic factors affecting the genetic diagnostic rate. Methods: Sixty-four patients with sporadic syndromic CHD aged <18 years underwent WES between May 2018 and December 2020 in a single tertiary center, and the association between genetic testing data and extracardiac phenotypes was analyzed. Results: Extracardiac phenotypes were measured as 3.66 ± 3.05 (standard deviation, interquartile range: 2–5)… More > Graphic Abstract

    Anomaly Detection in Textured Images with a Convolutional Neural Network for Quality Control of Micrometric Woven Meshes

    Pierre-Frédéric Villard1,*, Maureen Boudart2, Ioana Ilea3, Fabien Pierre1

    FDMP-Fluid Dynamics & Materials Processing, Vol.18, No.6, pp. 1639-1648, 2022, DOI:10.32604/fdmp.2022.021726

    Abstract Industrial woven meshes are composed of metal materials and are often used in construction, industrial and residential activities or applications. The objective of this work is defect detection in industrial fabrics in the quality control stage. In order to overcome the limitations of manual methods, which are often tedious and time-consuming, we propose a strategy that can automatically detect defects in micrometric steel meshes by means of a Convolutional Neural Network. The database used for such a purpose comes from real problem data for anomaly detection in micrometric woven meshes. This detection is performed through supervised classification with a Convolutional… More >

    Speak-Correct: A Computerized Interface for the Analysis of Mispronounced Errors

    Kamal Jambi1,*, Hassanin Al-Barhamtoshy1, Wajdi Al-Jedaibi1, Mohsen Rashwan2, Sherif Abdou3

    Computer Systems Science and Engineering, Vol.43, No.3, pp. 1155-1173, 2022, DOI:10.32604/csse.2022.024967

    Abstract Any natural language may have dozens of accents. Even though the equivalent phonemic formation of the word, if it is properly called in different accents, humans do have audio signals that are distinct from one another. Among the most common issues with speech, the processing is discrepancies in pronunciation, accent, and enunciation. This research study examines the issues of detecting, fixing, and summarising accent defects of average Arabic individuals in English-speaking speech. The article then discusses the key approaches and structure that will be utilized to address both accent flaws and pronunciation issues. The proposed SpeakCorrect computerized interface employs a… More >

    Congenital Heart Disease, Vol.17, No.3, pp. 365-374, 2022, DOI:10.32604/chd.2022.019126

    Abstract Background: Bilateral banding of the branches of the pulmonary artery in patients with hypoplastic left heart syndrome (HLHS) and other duct dependent critical neonatal heart malformations can significantly reduce the incidence of severe complications in the postoperative period, especially in severely unstable patients. In our study we compared different surgical techniques of bilateral pulmonary artery banding (PAB) in respect to their success in balancing systemic and pulmonary blood flow. Methods: We included 44 neonates with a HLHS and congenital heart diseases (CHD) with a functional single ventricle underwent a hybrid operation: bilateral PAB and patent ductus arteriosus stenting. The hybrid… More >

    Sound & Vibration, Vol.56, No.2, pp. 165-191, 2022, DOI:10.32604/sv.2022.015267

    Abstract Usage of rolling contact bearings in variety of rotor-dynamic applications has put forth a need to develop a detailed and easy to implement techniques for the assessment of damage related features in these bearings so that before mechanical failure, maintenance actions can be planned well in advance. In accordance to this, a method based on dimensional amplitude response analysis and scaling laws is presented in this paper for the diagnosis of defects in different components of rolling contact bearings in a dimensionally scaled rotor-bearing system. Rotor, bearing, operating and defect parameters involved are detailed for dimensional analysis using frequency domain… More >

    Sanam Safi1,2, Takato Yamasaki1,3, David J. Glidden4, Stephen P. Sanders1,5, Chrystalle Katte Carreon1,6,*

    Congenital Heart Disease, Vol.17, No.2, pp. 141-146, 2022, DOI:10.32604/chd.2022.019743

    Abstract A maternally inherited 828 kb microdeletion of 2q37.3 manifested in a 3-week-old premature boy as left juxtaposition of the atrial appendages associated with tricuspid atresia, double outlet infundibulum, subvalvar pulmonary atresia, large secundum atrial septal defect, and right aortic arch with mirror-image branching, consistent with developmental arrest early in heart looping. To the best of our knowledge, no previous 2q37 deletion syndrome has been reported with such a severe cardiac dysmorphology. Hence, this case adds to the cardiac phenotypes identified in 2q37 deletion syndrome. More >
