Published: February 2025

The voice is a natural biometric attribute for the verification and recognition of speakers. Using the Fourier transform of fractional order, it is possible to obtain characteristics of the speech signal in the time-frequency space with an added degree of freedom. The speech is represented in a different way compared to the traditionally Fourier transformation. This paper compares the performance of using the fractional Fourier transformation in the speakers’ verification in text-dependent systems, instead of the common representation using the standard Fourier transformation, of the Mel Frequencies Cepstral Coefficients. The results show that, for an appropriate choice of the order of the fractional Fourier transformation, an improvement has been obtained in the verification of the speaker.

Comparando la Eficiencia de los Gráficos T2 de Hotelling y de Clasificación por Rangos, Utilizando Diversos Estimadores de Localización y Dispersión
Authors: González Borja Joaquín , Montes Masmela Haider , Lugo Capera Oscar Andrés
Published: February 2025

Quality is defined simultaneously by a set of correlated variables for many products or services. To monitor a multivariate process, the classic control chart T2 (Hotelling (1947)) is often used. This chart is constructed under the assumption of normality of the observations and estimates of usual location and dispersion. It is well known that this chart is very sensitive to the presence of outliers in the historical data set, causing the masking effect and therefore several proposals to construct charts T2 with alternative estimators that have become more powerful and robust charts in the presence of outliers or faster detection of change in the mean vector have been proposed.
The normality of the observations is not always true in practice, then the nonparametric control charts are recommended in this case, one of them is the chart of a ranking method (Liu (1995)). Zertuchi and Cantu (2008), Velasquez and Moreno (2009), comparing the efficiency between the two charts above using conventional estimators under normal and devoid of it. This work, presents a comparative study about the efficiency of the two charts using various estimates of the mean vector and covariance matrix, in the presence of outliers in the construction phase. The efficiency of control charts is determined by the change in the early detection of mean vector. The efficiency of charts in this study is measured calculating the average run length (ARL) under control by statistical simulation through various environments encountered. We present the results obtained with their respective interpretations and conclusions.

ВЛИЯНИЕ СОСТАВА ЭЛЕКТРОЛИТОВ НА ЭЛЕКТРОХИМИЧЕСКИЕ ПОКАЗАТЕЛИ БЕЗАНОДНЫХ ЛИТИЙ-ИОННЫХ ЭЛЕМЕНТОВ
Authors: Абдрахманова А.Б. , Сабитова А.Н. , Омарова Н.М.
Published: February 2025

Безанодные литий-ионные аккумуляторы накапливают на 60% больше энергии на единицу объема, чем обычные литий-ионные элементы. Однако эти элементы, как правило, быстро теряют емкость и имеют короткий срок службы, а также, их практическому внедрению препятствуют значительные проблемы, такие как рост литиевых дендритов и низкая кулоновская эффективность циклирования.  
Разработка электролитических систем с оптимальной структурой и составом способствует развитию литиевых источников питания, в том числе и их электрохимических характеристик.  В литий-ионных аккумуляторах электролит действует как среда для переноса ионов лития между электродами во время процессов заряда-разряда. По этой причине этот компонент необходим для работы этих устройств. Обязательно нужно учитывать, что электролитические системы включают в себя компоненты в виде добавки, растворителя и соли.
Растворы электролитов на основе комбинации фторированных и традиционных карбонатных растворителей были исследованы в безанодных литий-ионных элементах с использованием в качестве анода медную фольгу и Li1.05Ni0.33Mn0.33Co0.33O2 в качестве катода.
Отличные эксплуатационные характеристики были достигнуты за счет замены традиционных алкилкарбонатных растворителей в растворах электролитов на смесь с фторированными сорастворителями. Использование фторэтиленкарбоната значительно улучшила циклическое поведение элементов, заряженных до 4,5 В. Достигнутое улучшение объясняется образованием стабильных и защитных поверхностных пленок на частицах катода благодаря уникальным поверхностным реакциям, которые возможны благодаря природе молекул фторированного растворителя. Поверхностные пленки, образующиеся на литиированных катодах из оксида переходного металла, изолируют активную массу, которая обладает высокой реакционной способностью по отношению к электрофильным алкилкарбонатам, от продолжающихся побочных реакций с частицами раствора. Исключительная электрохимическая стабильность этих растворов электролита делает их подходящими для других безанодных литий-ионных элементов.

Deep Learning for Early Skin Cancer Detection: A Comparative Study on Hybrid CNN Models
Authors: Matiray Sakshi , Singh Law Kumar
Published: February 2025

Globally, skin cancer—especially melanoma—is a major health concern, and better patient outcomes depend on early and precise diagnosis. Manual examination is a common component of traditional diagnostic techniques, but it is labor-intensive and subject to error. Promising approaches to automate skin lesion analysis have been made possible by recent developments in deep learning. In order to overcome the shortcomings of current approaches, this work investigates the creation of a hybrid deep learning model that blends VGG16 and ResNet50 architectures. The suggested approach incorporates sophisticated preprocessing methods, such as picture normalization and data augmentation, to improve feature extraction and classification accuracy using datasets like ISIC 2018 and HAM10000.Important results show that the hybrid model outperforms state-of-the-art benchmarks in performance metrics, achieving 98.75% training accuracy and 97.50% validation accuracy. The model’s enhanced precision (97.60%), recall (97.55%), and F1 score (97.58%) highlight how reliable it is at differentiating between benign and malignant tumors. The study also emphasizes how crucial it is to strike a balance between model complexity and computing performance in order to support practical clinical deployment. This study advances computer-aided diagnostic (CAD) systems for the identification of skin cancer by tackling issues including class imbalance and dataset unpredictability. The suggested method has a great deal of promise to improve early diagnosis, lessen the need for invasive treatments, and assist dermatologists in making clinical decisions. This paper thoroughly reviews current methodologies used in skin cancer detection, offering a timely resource for researchers developing automated and precise melanoma detection models.
Deformación y procesos tectónicos en la Península de Manta, Ecuador: una mirada a través de la estadística y cinemática de las discontinuidades
Authors: Lara Saavedra Hernan Javier , Briones Vera María José
Published: February 2025

El presente trabajo de investigación tuvo como objetivo determinar la orientación de los ejes y campos de esfuerzos y su correlación con el contexto tectónico regional de los afloramientos de la Formación San Mateo, Península de Manta, Ecuador. Se obtuvieron 123 datos estructurales de cuatro secciones, interpretados posteriormente mediante el análisis estadístico y cinemático. El análisis estadístico de discontinuidades fue elaborado mediante la proyección estereográfica de fallas y diaclasas en el Software Dips 5.1 y el Software ioGAS 7.4.2. Las subfeldarenitas y sublitoarenitas demuestran que el área de estudio estuvo sometida a campos de esfuerzo compresivos y distensivos con dirección W-E, SW-NE y NW-SE lo que indica una complejidad en la historia tectónica de la región. La orientación de esfuerzos distensivos y compresivos en la misma dirección indica la intermitencia en los procesos tectónicos generando estructuras distensivas en campos de esfuerzos compresivos. Las discontinuidades de componentes cinemáticos de carácter transcurrente derivados del sistema transcurrente dextral indican la presencia de una deformación horizontal significativa en la región. Los esfuerzos compresivos y distensivos en la Península de Manta se calcularon como la orientación NO-SE representa al esfuerzo principal (σ1) mientras que la orientación NE-SO representa el esfuerzo menor (σ3). El gráfico de Roseta muestra claramente la dirección N-S en un rango de 0.0°-20.0° en las diaclasas. Se obtiene como resultado de los controles estructurales, dos eventos estructurales del fallamiento que tienen un buzamiento alto y con orientación NNE-SSO y con orientación NNO-SSE. El buzamiento para ambos eventos varía entre 87.9° y 89.8°. La Península de Manta tiene una colisión con la Cordillera de Carnegie que genera un margen cóncavo hacia el Océano Pacífico similar al sistema de subducción de las Marianas.
Revisiting the latest Jurassic-earliest Cretaceous Los Santos Formation, Eastern Cordillera of Colombia. B – A transgressive river mouth deposit in a syntectonic scenario
Authors: Laverde Montaño Fabio
Published: February 2025

Durante la historia de los trabajos de investigación sobre el origen de la Formación Los Santos y su significado en el área de Mesas y Cuestas (Cordillera Oriental de Colombia), se le ha asignado un ambiente de depósito, ya sea enteramente marino o completamente fluvial. Con base en la segmentación litoestratigráfica y el análisis de asociación de facies, brindó pistas importantes para la interpretación de los ambientes de depósito y particularmente relevantes para evaluar sedimentológicamente los cambios en la sucesión estudiada. Este estudio muestra para la parte inferior de la unidad (segmento A) el desarrollo de depósitos aluviales, trenzados y meandriformes en el bloque constituido al este de la falla del Suárez y al sur de la falla transversal Los Montes. Hacia el norte la sucesión de Los Santos parece estar relacionada con la actividad de las fallas de Lebrija, Solferino y Bucaramanga, presentando una posible fuente de sedimentos de la Formación Jordán. Al sur de la falla de Sogamoso y al oeste de la falla de Suárez, se registran depósitos fluviales, en su mayoría meandriformes, en el segmento A. Hay algunos indicios de influencia de las mareas en el depósito suprayacente de textura más fina (segmento B), interpretado como la parte central de un estuario. Este depósito dominado por lodo ampliamente distribuido está cortado por una superficie de barranco de marea (tRS1) y cubierto por una mezcla de depósitos dominados por arena en la desembocadura del estuario (segmento C), que comprende dunas compuestas dominantes y bancos de arena intermareales. Sin embargo, el proceso de consolidación de este depósito en la desembocadura del estuario fue seguido por pequeños episodios regresivos y transgresivos registrados en el segmento D, en respuesta a fluctuaciones en el nivel de base, posiblemente reguladas por actividad tectónica.

Published: February 2025

У статті досліджено актуальне питання мотивації працівників підприємства в умовах сучасних викликів. Відзначено, що ключовим чинником успішного функціонування підприємств та підвищення їх конкурентоспроможності є мотивований персонал. Сьогодні в умовах нестабільності кожному керівнику бажано переглянути мотиваційні механізми, змінити інструменти управління та провести дослідження щодо існуючих потреб персоналу. Важливо не забувати, що високий рівень стресу та тривоги негативно впливає на продуктивність і прагнення досягати результатів, тому керівництво має шукати шляхи подолання негативних наслідків таких умов на робочому місці. Дієва система мотивації повинна заохочувати керівників підприємств і стимулювати працівників до безперервного розвитку. Впровадження нових та нестандартних підходів до мотивації дозволяє залучати висококваліфікованих спеціалістів та значно покращувати лояльність постійних працівників. Дослідження показують, що найефективнішою є система мотивації, яка поєднує матеріальні та нематеріальні стимули, а також інноваційні та нестандартні підходи. Розглянуто та досліджено питання зарубіжного досвіду використання системи оплати праці та мотивації працівників підприємства, нормування праці в розвинених країнах як основних взаємопов’язаних чинників посилення зацікавленості працівників у кінцевих результатах господарської діяльності. Обґрунтовано авторське бачення мотиваційного механізму трудової активності працівників. Ключовим інструментом мотиваційного механізму є формування мотиву до праці та ухвалення рішень щодо трудової діяльності (або бездіяльності) з метою задоволення потреби. Внутрішня мотивація пов’язана з сутністю роботи та її значущістю для працівника, тоді як зовнішня мотивація спрямована на стимулювання праці з боку адміністрації підприємства.

Identity Construction through Images of Clothing in Fleur Adcock’s Poetry
Authors: Wu Yuxuan
Published: February 2025

This study examines how Fleur Adcock, a New Zealand-born British poet,
establishes identities through images of clothing in three of her poems. Adcock’s
acute observations of clothing reflect the close link between dress and the
construction of the self and our place in society. In “The Soho Hospital for
Women,” Adcock portrays clothing as a crucial aspect of personal identity, while
in “Londoner” clothing reflects the conflict of the divided self. “Witnesses”
reconstructs female identity under patriarchy by emphasising the different
functions of clothing for men and women in the courtroom.

Освіта та підготовка кваліфікованих офіцерів в умовах війни та відбиття агресії має вирішальне значення для розбудови спроможності діяти в бойових умовах, враховуючи мінливий характер війни та стрімкий розвиток подій. Існують обмеження, зумовлені багатьма факторами та форматом освіти: необхідно підготувати якомога більше фахівців у найкоротші терміни, забезпечивши найвищу якість; необхідно фактично трансформувати освіту відповідно до вимог сучасності, щоб виховувати лідерів, здатних приймати нестандартні переможні рішення. Крім того, відповідно до усталених євроатлантичних підходів та прагнень України до членства в Альянсі, існує потреба у впровадженні стандартів та підходів НАТО й в освіті.
Крім того, необхідність освоєння нових форм і способів ведення бойових дій, поступове впровадження в діяльність військових формувань стандартних для НАТО процедур прийняття військових рішень, а також потреба в утриманні значної кількості військових формувань ставлять на порядок денний питання зміни підходів до навчання та підготовки військовослужбовців.
Протягом останніх років Національний університет оборони України став сучасним та провідним освітнім хабом, який підтримує зміни та надає допомогу, в тому числі методичну, іншим військовим навчальним закладам тактичного рівня з метою недопущення зниження якості підготовки військових фахівців з вищою військовою освітою.
Досвід організації освітнього процесу в умовах відбиття збройної агресії є унікальним та важливим. Фактично необхідно виконати комплексне завдання: освітній процес, відбиття збройної агресії, трансформація системи військової освіти та впровадження отриманого досвіду бойових дій для забезпечення підготовки кваліфікованих кадрів.

Published: February 2025

The rapidly increasing popularity of K-dramas among Muslim students in Indonesia has raised concerns about their impact on their religious values, as intense exposure to the culture and lifestyle depicted in K-dramas may influence Muslim students' religious perceptions and practices. In this case, this study aims to examine whether there is a correlation between the intensity of watching K-dramas and changes in religious values and practice among Islamic Education students from the batch of 2019 at UIN Raden Intan Lampung. The research uses a quantitative survey method by collecting data through a Likert scale questionnaire. The data analysis used Pearson Product-moment correlation analysis and simple linear regression. The results indicate that a significance value of 0.011 < 0.05 was obtained, leading to the rejection of H0 and acceptance of H1. This suggests a significant influence between the intensity of watching K-dramas and changes in student religious values and practice. Therefore, it is recommended that students be wiser in using their time and increase their religious activities. Moreover, educational institutions should also strengthen programs that support religious practices.

Electrical and Thermal Simulations of a Lithium- Ion Battery Cell: A Comparative Study of Commercial Software Platforms
Authors:   College of Engineering Technology, Ferris State University, Big Rapids, Michigan, USA, Liu Yiqun
Published: February 2025

Commercial software tools have become essential for modeling and simulating lithium-ion batteries,
offering researchers and engineers powerful platforms to analyze battery behavior under various operating
conditions. Among the most widely used tools are MATLAB/Simulink, COMSOL Multiphysics, and
ANSYS Fluent, each offering unique capabilities for electrical and thermal simulations. MATLAB/
Simulink is popular for its user-friendly environment and fast execution of simplified lumped-parameter
models, while COMSOL Multiphysics and ANSYS Fluent enable detailed, physics-based simulations
with higher spatial resolution. In this paper, the performance of MATLAB/Simulink, COMSOL
Multiphysics, and ANSYS Fluent is compared by modeling and simulating a lithium-ion polymer battery
cell designed for electric vehicle applications. All the parameters required for model development are
obtained from experimental data. MATLAB/Simulink is used to simulate the effects of terminal current
and ambient temperature on the battery’s discharge voltage and usable capacity. COMSOL Multiphysics
and ANSYS Fluent are employed to simulate cell terminal voltage and temperature distribution profiles
over the battery cell surface under various continuous charge and discharge conditions. Additionally,
ANSYS Fluent is used to model the surface temperature distribution caused by an internal short-circuit
resulting from foreign object penetration. The simulation results are validated using experimental data,
showing good agreement for both electrical and thermal behavior under different loading and ambient
conditions. The comparison highlights that MATLAB/Simulink is particularly well-suited for quick,
zero-dimensional lumped simulations of battery electrical and thermal responses due to its simplicity
and computational efficiency. In contrast, COMSOL Multiphysics and ANSYS Fluent involve more
complex model setups but offer significant advantages for performing detailed three-dimensional
simulations, capturing spatial distributions of current and temperature across the battery cell. These
insights are valuable for selecting the appropriate simulation tool based on the complexity and goals of
battery modeling applications.
