Inspection for non-planar shaped welded joints of pipes using FMC ultrasonic technique
Authors:   Hitachi Ltd, Yamaguchi Sho ,   Hitachi Ltd, Kitazawa So ,   Hitachi-GE Nuclear Energy, Ltd., Nidaira Yasuhiro
Published: July 2023

In applying ultrasonic testing (UT) to pipes with welded joints, one of the challenges is about the access limitation of UT probes caused by non-planar weld reinforcement profiles. One way to avoid this problem is to remove weld reinforcement for ensuring the contactability of a probe on welded parts. However, the removing process for flatten weld reinforcement needs extra day per joint and might damage pipes surface.

To overcome this issue, we have been developing a proprietary UT method that enables inspection of non-planar welded joints using the Full Matrix Capture (FMC) and the Total Focusing Method (TFM). A specially designed wedge is used between a probe and a welded part in order to extract the weld surface shape from the recorded data. In the TFM, multilayer propagation paths are analyzed with considering refractions at interfaces between the layer and the weld surface. The analysis is based on the Fermat's principle of least time, whereas this is generally known to be a time-consuming process. With the aim of performing real-time scanning in inspection to pipes on weld reinforcement, the shape of the wedge is optimized for welded joints to reduce the calculation time of the multilayer analysis. In this presentation, we will report the developed FMC/TFM technique and, furthermore, the validation results using pipe specimens with weld reinforcement.

Ultrasonic probes are an integral part of the automated ultrasonic non-destructive inspection machines to detect and size the defects in a wide range of materials in production lines. A complete quantitative assessment of the performance characteristics of an application-specific ultrasonic probe is needed to be evaluated on the basis of the European Standard DIN EN ISO 22232-2. This requirement not only improves the quality assurance of the manufactured probes but also provides the useful technical data to the end-user to optimize the ultrasonic testing on-site. In addition, the evaluation of probe characteristics should be carried periodically throughout their service life. The main aim of this work is to develop and validate a novel ultrasonic immersion scanner for the quantitative measurement and evaluation of ultrasonic sound beam characteristics of an application-specific UT Probe. A novel ultrasonic immersion scanner integrated with high-precision motion control unit (Hexapod) with six axes is developed to measure the full ultrasonic probe characteristics, which include the squint angle measurement in three different planes (XY, XZ, and YZ), RF-signal and its frequency spectrum at watersteel interface and sound beam parameters including the angle of beam divergence in different directions. The automated scanning, data acquisition, evaluation, visualization and test report generation are performed based on DIN EN ISO 22232-2. The measured sound beam characteristics of both focused and non-focused applicationspecific ultrasonic probes with center frequencies ranging from 0.2 - 15 MHz using the pulse-echo technique on a 3 mm half-ball steel reflector are presented. The quantitative analysis of the measured sound field parameters and the acceptance criteria in accordance with DIN EN ISO 22232-2 are discussed. By using the newly developed automated immersion scanner, we achieved a few micrometer (~15 µm) spatial resolution in the measured sound field patterns and a good angular resolution (~0.05°) in the squint angle measurement of a wide range of UT probes.

Metal based additive manufacturing techniques such as laser powder bed fusion (LPBF)

can produce parts with complex designs as compared to traditional manufacturing. The

quality is affected by defects such as porosity or lack of fusion that can be reduced by

online control of manufacturing parameters. The conventional way of testing is time

consuming and does not allow the process parameters to be linked to the mechanical

properties. In this paper, ultrasound data along with supervised learning is used to

estimate the manufacturing parameters of 316L steel cubes. Nine cubes with varying

manufacturing parameters (speed, hatch distance and power) are examined with

ultrasound using focused transducers. The volumetric energy density (VED) is calculated

from the process parameters for each cube. The ultrasound scans are performed in a dense

grid in the built and transverse direction. The ultrasound data is used in partial least square

regression algorithm by labelling the data with speed, hatch distance and power and then

by labelling the same data with the VED. These models are computed for both

measurement directions and as the samples are anisotropic, we see different behaviours

of estimation in each direction. The model is then validated with an unknown set from

the same 9 cubes. The manufacturing parameters are estimated and validated with a good

accuracy making way for online process control.

Accurate ultrasonic imaging and inspection of specimens with non-planar complex surfaces are often challenging from both transducer coupling and imaging perspectives. Several inspection strategies have been developed to inspect such complex interfaced components such as flat arrays with flexible wedges or water-filled chambers with a flexible membrane. In these methods, firstly surface profiles are estimated and then Fermat’s principle or other algorithms are applied to calculate delay laws. The main drawback of these methods is the longer computation time and therefore real time inspection is limited, also a coupling problem due to the complex geometries. Alternative approaches have been developed to compute the ultrasonic beam paths such as the Fast-Marching Method (FMM), Dijkstra’s algorithms, numerical analysis, bisection and root-finding algorithms for the inspection of complex surface components. These algorithms can be applied in two and three-dimensional domains resulting in high computation time. This work presents an experimental comparison of an iterative beamforming method for arbitrary shaped surface profile imaging against both Full Matrix Capture-Total Focusing Method (FMC-TFM) and CIVA simulation on an aluminium calibration block with Side drilled holes (SDHs) at various depths in the range of 15-80 mm. The performance of the iterative beamforming method is evaluated in terms of sensitivity, Signal to Noise Ratio (SNR) and Array Performance Indicators (API). The method provides a 2 dB improved SNR when compared to FMC-TFM.
Non-Destructive Examination of Metallic Idols and Statues in Religious Institutions - A Case Study
Authors:   Injotech India Private Limited, Ingale Tejas
Published: July 2023

Religious institutions typically have idols, statues and other items made up of different metals and alloys. The Hindu religion involves idol worship on a daily basis regularly over the course of a year. Most of the temples are hundreds of years old. Centuries of handling the idols leads to their exposure to water, acids, alkalies, environmental conditions and stresses. Degradation in quality and loss of properties is expected. Thus, determining the condition and quality of the various idols becomes imperative. Nondestructive examination of a 16th Century Hindu temple was carried out in the Maharashtra state of India. The objective was to determine the material constitution and construction method for the idols for conservation, preservation and re-constitutional purposes. The NDE methods used included Positive Material Identification using X-Ray Fluorescence (XRF) and Computerised Radiography (CR). Material constituents of the idols were determined. Internal conditions and flaws such as cracks, disjoints, disbonds were also looked at. A conclusion was drawn regarding the condition and future life of the idols. It was also determined whether NDE can be effectively used for carrying out remaining life assessment of art and cultural artefacts and its use in their restoration. Determination of century-old technologies and their comparison with present-day technologies can also be evaluated.

In this work a new approach for in-line quality inspection of drilling holes in glass reinforced fibre composites (GFRP) is presented. The method relies on Terahertz radiation and its large penetration depth in non-conductive materials. By applying THz reflection imaging, 3D information such as interfaces or defects within the sample can be obtained. As a starting point, a laboratory setup based on an industrial THz time-domain spectrometer (TDS) in combination with linear stages for the sample manipulation is built. A software for measurement automatization and data acquisition is developed. Based on measurements performed on drilled GFRP plates, an algorithm highlighting possible defects within the measurement data is developed. The results correlate very well with x-ray tomography (XCT) measurements. Finally, the THz-TDS system is transferred onto an industrial robot and the THz signal synchronized with the position of the robot’s head, expanding the flexibility of the method regarding the applicability to a wide variety of specimen geometries.

Published: July 2023

The transient spectral element method (SEM) is a specific high order finite element method that is particularly accurate and fast with a low memory footprint, hence enabling 3D ultrasonic testing simulations on a standard PC. However, particular care in its settings and hybridization with a semi-analytical solution remains a major challenge when seeking for both practicality and performance. A natural hybrid strategy consists of coupling a field calculated by ray tracing in the defect-free object to a SEM subdomain wherein the perturbation is enclosed, then synthesizing the signal with a reciprocity argument. The difficulty is to define the suited coupling strategy when the flaw response interacts with the back wall. In a highly heterogeneous medium, it may even become necessary to widen the numerical domain to the entire thickness of the inspected object and, therefore, to ensure the performance of the SEM through a custom discretization strategy. Here we present different customized uses of the SEM for practical ultrasonic inspection applications and discuss how they complement the ray tracing solution.
Experimental verification of phased array annular probe in ultrasonic immersion setting
Authors:   University West, Sahl Mikael ,   University West, Wirdelius Håkan
Published: July 2023

With the ongoing development of materials and manufacturing techniques, new product design opportunities manifest themselves. However, care must be taken when applying techniques and material where there is less inherent knowledge about different parameters’ effect on the integrity of the final component. In conjunction with destructive testing of components, non-destructive evaluation (NDE) provides valuable insight into the manufacturing process reliability, as well as the possibility for subsequent future in-service inspection. Phased array ultrasonic testing (PAUT) facilitates the inspection of complex geometries on a wide set of material. Mathematical modelling of ultrasonic signal facilitates the optimization of inspection procedures by e.g., maximizing the probability of detection (POD) of specific defect types. In this paper, the response from an immersion annular phased array probe is experimentally validated to the output of the simulation software simSUNDT. In order to only validate the probe model (as both transmitter and receiver) a set of well-defined defects are used. The validity of the simulated amplitude response from side-drilled holes at a depth range of 20-115 mm is investigated. A total of 14 SDH holes in one test piece of is used as cases for validation. The results show a good correspondence between simulated and experimental data for the case where the probe is normal to the component surface.

Authors:   Turkish Aerospace, Sahin Utku ,   Turkish Aerospace, Atilgan Yagmur Akbulut ,   Turkish Aerospace, Kumbasar O Mert
Published: July 2023

Optical Solar Reflectors (OSR) are fully light-reflective materials, which are used in

satellite panels that bonded with metallic sheets with a layer of silicon type adhesive.

During the bonding process, entrapping of air bubbles in the bondline is the main

problem, and the detection of air bubbles is crucial for the thermal integrity of the panel.

The inspectability investigation established in this work is a complete methodology that

consists of the determination of the applicable NDT method, parameter optimization,

reference specimen design, and most importantly, execution of the POD analysis for the

detection reliability to implement the method into post-manufacturing NDI operations of

OSR panels. A comprehensive comparison of conventional and advanced inspection

methods were performed in this study, including sonic, ultrasonic, radiographic and

thermographic techniques. After trials on generic scale panels, high sensitivity surfaces

of OSR and large density differences of bonded elements lead to the selection of the lockin thermography technique. Next, an appropriate reference specimen was designed for the

POD approach with thermally representative artificial defects. The results show that the

lock-in thermography technique can detect air bubbles at the adhesive layer for sizes

larger than 20 mm2 with a probability of detection of 90% at a confidence level of 95%.

Moderate Way Implementing Rukyah and Hisab to Determine A New Moon in Ramadan
Authors: Afifi Abdullah A , Abbas Afifi Fauzi
Published: July 2023

Rukyah and hisab have already become critical discussions in Islamic knowledge. Controversy arose, and the debate continues today. Some scholars prefer to use one method over another, while some scholars today try to offer moderate approaches for better solutions and understanding. Scholars claim both rukyah and hisab using the prophet Muhammad's hadith references. In comparison, a modest society is accessible to apply rukyah as their way to determine the new Ramadhan, and some complex cultures are multicultural, multi sects, or have a wide coverage area. This complexity will affect the observation process's difficulty, accuracy, and potential differences. This situation needs sensible solutions to determine the new Ramadhan. This paper tries to elaborate on each approach used by scholars and authorities, its preconditions, and how the approaches should be moderated to determine the new moon optimally by developing a strategy that gives mutual feedback to each method.

The scholarly world is a divine devotion. It needs time and effort to be consistent and persistent in improving the understanding of society. The more literate society, the more hope for a better environment. Today's world needs more scholarly work not just to amaze the concept but also can impact society. Women's roles in education are tremendous to take learning environment from an early age. The references about women scholars are so limited that we will assume there is the little impact made. This paper shows how women's intellectual influence has made a massive contribution since the prophet Muhammad (PBUH) period. The shift in women's roles is contextual and depends on the understanding of society and the development progress of the education ecosystem itself. We hope the tremendous past work can inspire us to build an advanced learning society to improve the education process today.

Published: July 2023

Calculus is one of the most interesting fields of Mathematics yet difficult to pass. In this study, the common errors committed by the students were analyzed and categorized based on Newman’s error analysis guide. Using the quantitative research method, 10 Bachelor of Secondary Education major in Mathematics students enrolled in Calculus I and II were purposively chosen. The study hypothesized that no significant effects of the errors committed when classified according to types of errors and math fields to the overall performances in Calculus I and II of the students. Data collected were analyzed and interpreted using Mean Percentage Scores and Structural Equation Modelling. Based on the results, students commit errors mostly in differentiating functions involving logarithms. In terms of integration, students commit errors more on algebraic functions. Based on Newman’s error analysis, errors committed by mathematics major students are categorized into comprehension in both differentiation and integration processes. The result reveals that while students are equipped with the necessary skills needed for the transformation, process, and encoding, comprehension of the pre-requisite concepts should be strengthened and given attention specifically in algebraic and logarithmic functions. Finally, an instructional material addressing the identified common errors was developed.

Parents and teachers should have more regular meetings to resolve the conflicts.
Understanding the Challenges of Affordable Housing Provision in Nigeria: An Analysis of Key Factors and Policy Implications
Authors: Enwin Anthony Dornubari , Ikiriko Tamunoikuronibo Dawaye
Published: July 2023

Affordable housing remains a critical issue in Nigeria, with numerous factors contributing to its scarcity. This paper examines the key factors contributing to the lack of affordable housing in Nigeria, including high construction costs, inadequate urban planning and land use, limited access to finance, inadequate infrastructure, corruption and bureaucracy, limited government support and policy implementation, and high urban area land costs. High construction costs escalate housing prices, posing challenges for low-income earners to afford homes. Inadequate urban planning and land use policies result in spatial inequality, scarcity of available land, and increased housing costs. Limited access to finance restricts low-income earners' ability to secure mortgage financing for affordable homes. High urban area land costs further exacerbate the affordability challenge. Inadequate infrastructure hampers housing development and increases construction costs. Limited government support and policy implementation hinder effective affordable housing provision. Corruption and bureaucratic bottlenecks also hampers the process. These factors underscore the complex nature of the affordable housing crisis in Nigeria and necessitate a comprehensive approach involving collaboration between the government, private sector, and communities. Policy recommendations include improving policy implementation, fostering public-private partnerships, enhancing access to finance, strengthening urban planning strategies, investing in infrastructure, and providing increased government support for affordable housing initiatives. Addressing these factors will contribute to the creation of sustainable and inclusive housing solutions, ensuring that affordable homes become accessible to all Nigerians.

El trigo es uno de los cereales más importantes en la elaboración de pan, ya que la funcionalidad que poseen sus proteínas lo hace único. Se realizó análisis físico - químicos a todas las muestras de harinas que se seleccionaron. Con el fin de obtener una harina que se adapte a los procesos de elaboración de pan y pastas alimenticias. Se seleccionaron cinco harinas procedentes de cereales y un tubérculo (trigo, maíz, cebada, quinua y papa), el diseño experimental que se siguió fue el diseño de un solo factor completamente aleatorizado. Los parámetros que se utilizaron para determinar las características y la funcionalidad de las proteínas de estas harinas fueron la capacidad de retención de disolventes y la determinación de grupos disulfuro y sulfhidrilo, ya que estos se encuentran ligados directamente a la estructura cuaternaria y terciaria de las proteínas. Se estableció como mejores tratamientos a la harina de cebada cañicapa y el trigo nacional cojitambo. La presente investigación tuvo como objetivo determinar qué tipo de harina proveniente de distintos cereales (maíz, cebada, quinua, trigo nacional) y tubérculo (papa) podría sustituir a la harina de trigo según las características y funcionalidad de las proteínas en panificación y fideos.

El estudio se realizó en el cantón Quevedo, provincia de Los Ríos, Ecuador, con la finalidad de identificar, analizar y clasificar productos y subproductos agrícolas utilizados en la alimentación animal por parte de pequeños productores agropecuarios. La metodología empleada comprendió dos fases: de campo (encuesta a 64 productores) y de laboratorio; en la primera fase se recolectó información sobre la identificación del predio y los productos y/o subproductos que los productores utilizan en la alimentación animal, en la segunda fase se tomaron muestras representativas de los productos y/o subproductos que han dado buenos resultados en la alimentación animal, determinándose por triplicado los siguientes análisis: Materia Seca (MS), Energía Bruta (EB), Proteína Cruda (PC), Extracto Etéreo (EE), Fibra Cruda (FC), Ceniza (C) y Calcio (Ca). Los resultados demuestran que en la zona de estudio se utilizan 36 productos y subproductos agrícolas (plátano, cáscara de maracuyá, residuos de arroz y maíz, fruta de pan, tapioca, hojas de yuca, entre otros) de los cuales 47.22% tienen alto contenido de energía (≤20% PC y hasta 18% de FC), 19.44 % tienen altos porcentajes P (≥ 20% PB y ≤ 18% de FC) y un 33,34% poseen en su composición altas cantidades de FC (≥ 18 % de FB y ≤ 20 % de PC). La información obtenida constituye una línea base, que podría ser utilizada como herramienta de referencia con el propósito de promover nuevas estrategias relacionadas con la alimentación animal, proveyendo una alternativa de fácil utilización para los pequeños productores.

Mungbean [Vigna radiata (L)], an important grain legume in Bangladesh, is grown during kharif1 (pre-monsoon) season, when drought is a common abiotic stress. This study was thus conducted in pots inside semi-controlled vinylhouse to assess the effect of water stress on growth and yield of some popular mungbean varieties, viz. BUmug 2, BUmug 4, BARI Mung-5, BARI Mung-6, Binamoog-5 and Binamoog-8. Two water regimes, 80% field capacity (FC; non-stress) and 50% FC (water stress) were maintained. The experiment was laid out in a completely randomized design having four replications. Under water stress the variety Binamoog-5 had the largest leaf area (850.4 cm2 ), while BUmug 4 had the smallest (695.1 cm2 ). At maturity the reduction of shoot dry weight due to water stress was the highest in BUmug 4 (20.6%) while that was the lowest in Binamoog-5 (12.5%). The highest reduction of pod number due to water stress was recorded in BUmug 4 (45.1%) and the lowest was in Binamoog-5 (32.9%) followed by Binamoog-8 (34.5%). The highest reduction in seed number pod-1 due to water stress was in BUmug 4 (21.8%) and the lowest was in Binamoog-5 (16.79%). Water deficit did not exert significant effect on 100-seed weight in the varieties except BUmug 4. Binamoog-5 had the maximum yield plant-1 under both control (12.8 g) and water deficit (7.4 g) conditions followed by Binamoog-8, while BUmug 4 had the lowest in both control (11.6 g) and water deficit (6.3 g) conditions. It was concluded that Binamoog-5 and Binamoog-8 can be potential varieties for field trial for cultivation under water deficit conditions.
Gender-Specific Variations in BMI Status of Students' Social Networking Site Usage: A Comprehensive Statistical Analysis

Published: July 2023

The present study investigates the association between gender and body mass index (BMI) status through a comprehensive statistical analysis. A diverse sample of participants was utilized to examine the prevalence and distribution of different BMI categories among males and females. Statistical techniques, including crosstabulation, chi-square tests, and correlation analysis, were employed to analyze the data and determine the significance of the relationship. The results of the analysis revealed distinct gender-specific variations in BMI status. Among females, the majority fell into the normal weight category (n=89, 49.0%), while males showed a higher prevalence of overweight (n=32, 21.5%). The crosstabulation table further demonstrated the distribution of participants across gender and BMI status categories, providing valuable insights into the prevalence of specific BMI statuses among males and females. The chi-square tests confirmed a significant association between gender and BMI status (p < 0.001), indicating that gender significantly influenced the likelihood of being in specific BMI categories. This finding emphasizes the importance of considering gender-specific factors in understanding and addressing BMI-related health disparities. The correlation analysis revealed a moderate positive association between gender and BMI status (r=0.205, p < 0.001), indicating that as gender changed from female to male, there was a tendency for BMI status to shift from lower categories to higher categories.
