Development of Fringe Image Processing Algorithms for Tomograpic Reconstruction of Temperature Field in an Axisymmetric Medium
Authors: Khaleel Ibtihal 
Published: January 2025

This work is part of the development of algorithms and digital tools for the tomographic reconstruction of the (3D) temperature field from images resulting from thermal metrology based on two optical techniques (Moire deflectometry and holographic interferometry). It is intended not only for digital scientists and image processing specialists but also for researchers and practitioners in instrumentation and measurement by non-invasive techniques in general and in thermal metrology by optical techniques in particular Tomography by optical techniques of axisymmetric transparent media, the main subject of application of this thesis, is a perfect example of an imaging system based on an elementary mathematical property (the Abel transform and its inverse in this case). This property comes up against in its practical application the hypersensitivity to noise and problems due to the intrinsic characteristics of this transform. However, the study of transparent media such as air in our case, which does not present any radiative, absorption or diffusion properties, makes the images resulting from optical techniques unusable only after a treatment which precedes the inverse calculation of the Abel transform. This treatment thus limiting the development of 3D imaging requires special attention. Furthermore, the tomographic reconstruction of the temperature field of such an environment will be done in two processing parts, the first of which will focus on the analysis of mud figures, while the second is dedicated to solving the inverse problem generated by the Abel transform.

Published: January 2025

Objective: Develop a mathematical model to predict the loss of organic carbon in high Andean micro-watersheds of Sangay National Park.

Method: The model is based on the analysis of soil physicochemical variables, such as carbon content and carbon/nitrogen ratio (C_N), which is an indicator of soil quality. Using multiple linear regression techniques, the model evaluates the impact of factors such as carbon and nitrogen content on COS loss, with predictions adjusted to two depths: 30 cm and 60 cm, complying with the requirements of normality, homoscedasticity and statistical independence, and explaining a high variability in the behavior of COS and the C_N ratio under different conditions.

Results and Discussion: The results highlight the influence of key factors such as nitrogen percentage and relative density on carbon sequestration, and reveal that nutrient-rich soils show greater resistance to erosion, while soil compaction negatively affects the C_N ratio and reduces carbon storage capacity. Furthermore, the study suggests that COS in deep layers, such as at 60 cm, is more stable and less vulnerable to surface erosion. These findings strengthen the proposed model as a reliable quantitative predictive tool for the conservation of high Andean soils against water erosion and provide a comprehensive analysis of carbon dynamics in high mountain soils. Finally, this study provides a robust mathematical model for monitoring soil organic carbon (COS) dynamics in high Andean soils subject to water erosion. The physicochemical variables analyzed allow a comprehensive approach to accurately estimate COS loss and the carbon-nitrogen (C_N) ratio. In addition, these variables offer practical guidelines to anticipate and mitigate the effects of water erosion and promote sustainability in vulnerable high mountain ecosystems.

Research Implications: The main complications of the current study were the climatic conditions of the study area, since at times it was extremely cold with temperatures below 0º. In addition, the cost of using the laboratory to obtain the results of the samples obtained in the field. Also, by including agricultural areas within our study area, there were complications related to the owners of the areas, however, we were able to reach an agreement through our own economic resources. Finally, limited time was an important constraint to obtain more robust results.

Originality/Value: The originality of this article consists in the correct execution of a model based on the analysis of soil physicochemical variables and the obtaining of results in a study area with remote complexity with respect to its climatic conditions.

Published: January 2025

The effect of Ni content in weld consumables on the preferential weld corrosion (PWC) of welded pipeline steel for hydrocarbon and produced water service has been investigated using the galvanostatic method as a preliminary assessment tool. The method involves the application of a modest anodic current to the weldment over a short period, in this case, 62 h. The distribution of material loss and the extent of PWC is then characterized by 3D profiling. Testing was conducted for 0% Ni, 1% Ni, and 2% Ni weld fillers in 50 g/L NaCl at 60°C with 1 bar CO2. For these sweet environments, the results demonstrate an increased resistance to corrosion of the weld metal and heat-affected zone (HAZ) for the Ni-weld filler, compared to the weld metal free of Ni and the parent steel. However, for all weldments, the fusion zone and HAZ/parent steel interface were more prone to attack than the parent steel, albeit the addition of Ni reduced the extent of corrosion at the fusion zone.
Enhancing diagnostic accuracy in breast cancer: integrating novel machine learning approaches with enhanced image preprocessing for improved mammography analysis
Authors: Mehrabi Mohsen , Salek Nafise 
Published: January 2025

PurposeThis study explored the use of computer-aided diagnosis (CAD) systems to enhance mammography image quality and identify potentially suspicious areas, because mammography is the primary method for breast cancer screening. The primary aim was to find the best combination of preprocessing algorithms to enable more precise classification and interpretation of mammography images because the selected preprocessing algorithms significantly impact the effectiveness of later classification and segmentation processes.Material and methodsThe study utilised the mini-MIAS database of mammography images and examined the impact of applying various preprocessing method combinations to differentiate between malignant and benign breast lesions. The preprocessing steps included removing label information and pectoral muscle, followed by applying algorithms such as contrast-limited adaptive histogram equalisation (CLAHE), unsharp masking (USM), and median filtering (MF) to enhance image resolution and visibility. After preprocessing, a k-means clustering technique was used to extract potentially suspicious regions, and features were then extracted from these regions of interest (ROIs). The extracted feature datasets were classified using various machine learning algorithms, including artificial neural networks, random forest, and support vector machines.ResultsThe findings showed that the combination of CLAHE, USM, and MF preprocessing algorithms resulted in the highest classification performance, outperforming the use of CLAHE alone.ConclusionsThe integration of advanced preprocessing techniques with machine learning significantly enhances the accuracy of mammography analysis, facilitating more precise differentiation between malignant and benign breast lesions.

Published: January 2025

Abstract. Cloud shadows can be detected in the radiance measurements of the TROPOspheric Monitoring Instrument (TROPOMI) on board the Sentinel-5P satellite due to its high spatial resolution and could possibly affect its air quality products. The cloud-shadow-induced signatures are, however, not always apparent and may depend on various cloud and scene parameters. Hence, the quantification of the cloud shadow impact requires the analysis of large data sets. Here we use the cloud shadow detection algorithm DARCLOS to detect cloud shadow pixels in the TROPOMI absorbing aerosol index (AAI) product over Europe during 8 months. For every shadow pixel, we automatically select cloud- and shadow-free neighbour pixels in order to estimate the cloud-shadow-induced signature. In addition, we simulate the measured cloud shadow impact on the AAI with our newly developed three-dimensional (3D) radiative transfer algorithm MONKI. Both the measurements and simulations show that the average cloud shadow impact on the AAI is close to zero (0.06 and 0.16, respectively). However, the top-of-atmosphere reflectance ratio between 340 and 380 nm, which is used to compute the AAI, is significantly increased in 95 % of the shadow pixels. So, cloud shadows are bluer than surrounding non-shadow pixels. Our simulations explain that the traditional AAI formula intrinsically already corrects for this cloud shadow effect via the lower retrieved scene albedo. This cancellation of cloud shadow signatures is not always perfect, sometimes yielding second-order low and high biases in the AAI which we also successfully reproduce with our simulations. We show that the magnitude of those second-order cloud shadow effects depends on various cloud parameters which are difficult to determine for the shadows measured with TROPOMI. We conclude that a potential cloud shadow correction strategy for the TROPOMI AAI would therefore be complicated if not unnecessary.

La enfermedad de Parkinson (EP) es una patología neurodegenerativa que afecta el sistema nervioso central, caracterizada por manifestaciones clínicas motoras y no motoras. Dentro de las dificultades motoras se encuentra la disartria hipocinética la cual afecta la voz de quienes padecen la enfermedad. El propósito del presente trabajo es describir desde una mirada multidimensional de la voz aspectos tales como: medidas acústicas, aerodinámicas y laringoscópicas, en un grupo de sujetos con EP. Para tal propósito, se realizó un estudio descriptivo de corte transversal, en el que se evaluaron 10 sujetos con EP en diferentes estadios de evolución de la enfermedad. Se evaluaron parámetros acústicos mediante programa Praat, tiempo máximo de fonación y configuración glótica a través de una nasofibrolaringoscopía.
En la evaluación acústica se halló una variación de la frecuencia fundamental encontrándose levemente aumentada en hombres y disminuida en mujeres. El Jitter se encontraba normal. Cuatro sujetos arrojaron un valor de shimmer aumentado y dos presentaron un aumento del nivel de ruido. La relación alpha ratio se encontraba con valores negativos en todos los participantes. En el tiempo máximo de fonación, 60% de la muestra presentó valores descendidos. A nivel visual en el cierre glótico se evidenciaron 6 sujetos con un cierre deficiente y en actividad supraglótica 5 participantes presentaron contracción de bandas.
Los sujetos con Parkinson participantes presentan alteraciones en los parámetros acústicos de la voz, tiempo máximo de fonación y configuración glótica. Estas dificultades se hacen más notorias a medida que avanza la enfermedad y las dificultades motoras son más evidentes.

Dattatreya’s Philosophical Teachings: An Ecocritical Perspective
Authors: Dr. Damaru Chandra Bhatta  
Published: January 2025

This article explores Dattatreya’s philosophical teachings from an ecocritical perspective. Also, it reviews the perspective of ecocriticism and shows how that ecocritical perspective is useful to analyze the philosophical teachings of Dattatreya, which he learned from his 24 gurus of the natural and human world. To explain Dattatreya’s teachings from the perspective of ecocriticism, we look at how they show and affect the connection between people, nature, and culture. Ecocriticism studies how literature and culture relate to the environment, highlighting how important nature is to human life. Ecocriticism was a term coined in the late 1970s by combining “criticism” with a shortened form of “ecology”—the science that investigates the interrelations of all forms of plant and animal life with each other and with their physical habitats. Ecocriticism, also known as environmental criticism or green studies, refers to writings that examine the relationship between literature and the environment, with a strong focus on the harm humans are causing to nature. Dattatreya, a respected sage and God in Hindu tradition, is famous for his special way of achieving enlightenment. He learned from 24 different gurus (“teachers”) each representing various aspects of nature and life: earth, wind, sky, water, fire, moon, sun, pigeon, python, ocean, moth, bumblebee, elephant, honey collector, deer, fish, prostitute Pingala, osprey, baby, maiden, arrow-maker, snake, spider, and wasp. Dattatreya’s philosophy combines Vedantic and Yogic teachings, focusing on achieving self-realization and spiritual enlightenment. The story of Dattatreya, honored as an incarnation of the Divine Trinity of Brahma, Vishnu, and Shiva, appears in some Puranas and minor Upanishads. The 24 teachings learned by Dattatreya are worth discussing from an ecocritical perspective. These teachings, if followed, can save us from deteriorating ecological crises and degrading human values.
