Algorithms for extracting subsystems from a multilevel representation of a system of Boolean functions for joint minimization
Authors: Bibilo P. N. , Kirienko N. A. , Romanov V. I.
Published: January 2025

Objectives. The purpose of experimental research is to determine the effectiveness of new algorithms for extracting the so-called connected subsystems from formula descriptions of the original system of Boolean functions. Subsequently each of the extracted subsystems is minimized independently of the others, but the functions that make up each connected subsystem are minimized jointly.

Methods. Minimization of subsystems is performed in the class of multilevel BDD representations (BDD – Binary Decision Diagram) or Boolean networks. After obtaining minimized descriptions of circuits, specified as a set of interconnected Shannon expansion formulas that correspond to BDD, or as two-operand logical equations corresponding to Boolean networks, synthesis of logic circuits is carried out in the design library of custom digital CMOS ASIC (Application-Specific Integrated Circuits made using complementary metal oxide semiconductor technology). In Boolean networks, node functions can be the logical operations “conjunction” or “disjunction” over literals of Boolean variables. A literal is a Boolean variable or its inversion. Minimization of BDD representations is carried out according to the number of Shannon decomposition formulas, minimization of Boolean networks – according to the number of literals in the formulas defining the networks.

Results. The resulting logic circuits are compared in terms of chip area and speed (time delay). Experiments were carried out on 39 industrial circuit examples. The advantage (in 29 cases) of using the proposed subsystem extraction algorithms is shown compared to joint or separate minimization of the original system of Boolean functions, which is usually performed as the first stage of the synthesis of logic circuits.

Conclusion. The new algorithms for subsystem extraction proposed in the paper have proven their effectiveness in the execution of various programs for optimizing multilevel representations of systems of Boolean functions. The developed software package allows improving the results of technologically independent optimization used in the implementation of digital system projects in custom digital CMOS ASIC.
Verification of normalized online signatures without calculating dynamic features
Authors: Starovoitov V. V.
Published: January 2025

Objectives. Study of the method of verification of the authenticity of a human signature made on a tablet with a stylus and given three parameters: coordinates X, Y and pressure on the tablet P.

Methods. N genuine dynamic human signatures are given. Data describing different signatures made by one person always have a different number of points. The main variants of normalization of the original signature data are investigated. A model of an individual image of human signatures is built without calculating dynamic features. The method of dynamic time transformation (DTW) is used to compare similar data of different signatures. The results of this transformation are DTW-distances between the data of pairs of signatures. These distances serve as coordinates of a point in the feature space describing the similarity of a pair of signatures. A set of such points represents a model describing the similarity of genuine human signatures. The parameters of the signature being verified are compared with each of the N authentic signatures used to build the model for their proximity to the model. If more than half of these pairs are further from the model than a certain threshold T, the signature is considered fake.

Results. As a result of comparative experiments, a variant of normalization of initial data of dynamic human signatures was found, which allows verification of such signatures without calculating additional features usually calculated from the initial data X, Y, P.

Conclusion. Experiments to generate individual signature models for each of 230 people from the publicly available MCYT dynamic signature database (a subset of the DeepSignDB database) and verify the authenticity of 11,500 signatures made on behalf of these people showed a verification accuracy of 99.82 %. Half of them were genuine, half were fake.

Authors: Ponte Luiz Eduardo de Paula , Dalmas Fabrício Bau , Bulbovas-hueb Patricia
Published: January 2025

O meio ambiente se constitui como uma ideia fundante vinculada à própria sobrevivência de uma sociedade, assim, se entremostra como uma atuação com especial relevância do Estado. Por sua vez, o direito penal, como o braço de coibição mais intenso que dispõe o Poder Público, deve servir não somente como mecanismo repressivo, mas também, e no caso ambiental de maneira mais forte, como fator pedagógico para a criação de uma consciência geral protetivo de tal bem jurídico (meio ambiente). Este trabalho busca analisar o papel do direito penal como política de educação ambiental, sob a ótica da sua função ético-social, por meio de ampla revisão da literatura pertinente. A fundamentação bibliográfica mostra a educação ambiental como uma ação imprescindível para o sucesso da criação do sentimento social de tutela ambiental na sociedade, e o direito penal a função ético-social de conceder um caráter educativo por meio da publicização dos seus tipos criminais, e as suas respectivas consequências jurídicas.

Seizures are a common symptom of brain tumors, whether primary or metastatic. Seizures in patients with breast cancer can sometimes occur for reasons unrelated to the tumor, such as metabolic encephalopathy, cytotoxic chemotherapy, paraneoplastic syndromes, cranial irradiation, and stroke related to cancer. Many chemotherapeutic agents have also been reported to cause seizures (paclitaxel, cisplatin, 5-fluorouracil, methotrexate, and cyclosporine). We present the case of a 45-year-old female who experienced an acute seizure shortly after receiving an infusion of paclitaxel and carboplatin for grade 3 ductal breast cancer. This rare adverse drug reaction should raise awareness among physicians and pharmacists when treating cancer patients.

Published: January 2025

Genetic Algorithm (GA) often requires a long computation time due to the complexity of its processes. Therefore, efforts are needed to optimize GA computation time, particularly in scheduling lectures at the Electrical Engineering Study Program of Universitas Negeri Medan, which is the focus of this research. One possible approach is determining the appropriate mutation probability (Pm) value. This study employs the Mutation Probability Variation Method, where Pm is constrained between 0 and 1 and varied from a minimum value of 0.01 (1%) to a maximum value of 0.1 (10%). Simulations were conducted using Matlab R2012b, with constant parameters including a population size of 100 and a crossover probability (Pc) of 0.85. Iterations were performed to evaluate the effect of Pm on computation time and solution performance. The results show that at Pm = 0.06, the Genetic Algorithm achieved the fastest computation time, averaging 0.382 seconds. This study also identifies that GA computation time is significantly influenced by algorithm parameters and the complexity of the problem. By selecting an appropriate Pm, a balance between exploration and exploitation can be achieved, reducing computation time without sacrificing solution quality. This research contributes significantly to the development of more efficient algorithms for optimization applications, particularly in lecture scheduling.Waktu komputasi dalam Algoritma Genetika (AG) sering kali memerlukan waktu yang lama akibat kompleksitas komputasi yang dikerjakan. Oleh karena itu, perlu dilakukan upaya untuk mengoptimalkan waktu komputasi AG, khususnya dalam perencanaan jadwal kuliah di Program Studi Teknik Elektro Universitas Negeri Medan, yang menjadi objek penelitian. Salah satu upaya yang dapat dilakukan adalah dengan menentukan nilai probabilitas mutasi (Pm) yang tepat. Penelitian ini menggunakan Metode Variasi Probabilitas Mutasi, di mana nilai Pm dibatasi antara 0 hingga 1 dan divariasikan dari nilai minimum 0,01 (1%) hingga nilai maksimum 0,1 (10%). Simulasi dilakukan menggunakan perangkat lunak Matlab R2012b, dengan parameter konstan yaitu ukuran populasi 100 dan probabilitas crossover (Pc) 0,85. Proses iterasi dilakukan untuk mengevaluasi pengaruh Pm terhadap waktu komputasi dan performa solusi. Hasil simulasi menunjukkan bahwa pada Pm = 0,06, Algoritma Genetika mencapai waktu komputasi tercepat, yaitu 0,382 detik. Penelitian ini juga mengidentifikasi bahwa waktu komputasi AG sangat dipengaruhi oleh parameter algoritma dan kompleksitas masalah yang dihadapi. Dengan pemilihan Pm yang tepat, keseimbangan antara eksplorasi dan eksploitasi dapat dicapai, sehingga waktu komputasi berkurang tanpa mengorbankan kualitas solusi. Penelitian ini memberikan kontribusi signifikan dalam pengembangan algoritma yang lebih efisien untuk aplikasi optimasi penjadwalan kuliah.

Published: January 2025

Cette étude présente une recherche collaborative portant sur la relation école-famille, réalisée sur l’année scolaire 2022-2023 dans des écoles maternelles REP et REP+. Des équipes intercatégorielles ont coopéré pour instruire la question de l’absentéisme à l’école : enseignantes, encadrantes éducatives, chercheuses et une représentante de l’Association Quart Monde. L’objet de l’étude s’inscrit dans un projet où le préfixe « co » est un marqueur fort des associations générées : co-construction du projet de recherche, coéducation en jeu dans la promotion des apprentissages premiers et la lutte contre les inégalités dont l’absentéisme est un facteur non négligeable. Les motifs explicatifs avancées par les enseignantes ont permis de formaliser différentes variables dont les résultats montrent une relation significative entre l’absentéisme et certaines périodes de l’année scolaire : la période concernée dans la journée, la période selon les mois de l’année. D’autres variables significatives sont dégagées telles que le curriculum de l’élève, le rang dans la fratrie, l’activité professionnelle de la mère. Les résultats de la recherche sont doubles, d’une part sur des facteurs de l’absentéisme, d’autre part sur le principe même d’un projet où concurrent plusieurs dynamiques.

Published: January 2025

Cet article s’appuie sur les résultats d’une recherche collaborative entre les chercheuses et l’équipe pédagogique d’une école maternelle, en réseau d’éducation prioritaire renforcé, autour de la mise en place d’un dispositif classes ouvertes . Il interroge en quoi l’observation par les parents d’une séance de classe ouvre un accès, une qualification et une légitimation au rôle de parents d’élèves et à l’accompagnement de la scolarité de leur enfant. L’effet potentiel de cette recherche sur la perspective inclusive de cette école se situe à deux niveaux : l’accessibilité scolaire des parents participant au dispositif ; le développement du processus d’accessibilisation mené par l’équipe pédagogique. L’analyse d’entretiens de parents, ante et post observation de séance, permet de comparer l’évolution de leurs perceptions du comportement de leur enfant, des activités menées en classe et du travail de l’enseignante. Les perceptions sont plus précises et plus détaillées ; elles alimentent un regard et des perspectives nouvelles quant à la scolarité de leur enfant.
L’École des parents, une ébauche de ré-institution de l’ Autre ? De la normalisation à la participation politique de populations migrantes
Authors: Bednarek Dorothée , Armagnague Maïtena
Published: January 2025

Dans la sociologie classique comme dans la sociologie des migrations, la participation politique est souvent appréhendée comme un indicateur emblématique de participation sociale. Dans cette perspective, nous l’étudions avec l’analyse d’un dispositif à destination de parents migrants : L’École des parents. Cette participation politique est envisagée sous différentes formes, y compris minoritaires et contestataires. Nous observons comment un dispositif, pensé au départ pour la normalisation via l’éducation et le contrôle de parents migrants, peut être un vecteur d’expression politique et de reconfiguration des rites institutionnels. Nous soulignons ainsi que ce dispositif institutionnel, bien que conçu pour viser la normalisation des parents d’élèves a pour effet paradoxal de bâtir des ponts vers la connaissance de l’Autre, celui considéré socialement comme un étranger (Agier, 2022). Nous soulignerons ensuite comment ces initiatives, notamment parce qu’elles ne se départissent pas de leur caractérisation normative, permettent l’expression d’opposition ou de résistance, ces expressions participant finalement à la reconfiguration du dispositif institutionnel.

Published: January 2025

Purpose

To determine the status of depression and its key influencing factors among Chinese older adults in different living situations.

Method

Data of 7,092 older adults were obtained from the China Health and Retirement Longitudinal Survey. This study analyzed key variables influencing depressive symptoms using random forest modeling and logistic regression.

Results

The prevalence of depressive symptoms in older adults is 33.2%, with the highest prevalence of depression in older adults living alone (41.2%). Cognitive functioning and life satisfaction are psychological factors that affect older adults' mental health, whereas self-rated health and child relationship satisfaction are biological and social factors affecting their mental health, respectively. Furthermore, self-rated pain and limitations in activities of daily living were identified as risk factors for their mental health. Key factors affecting older adults' mental health differ between living situations.

Conclusion

Key factors of depressive symptoms in older adults differ across living situations, providing a priority and reference for differential prevention and precise intervention of depressive symptoms to promote a healthy aging process. Results of the current study may help clinicians better understand the pathogenesis of depression in older adults, guide clinical diagnosis and treatment, and develop individualized depression prevention and management strategies.

Authors: Cortés Sánchez Luis Miguel , Terrados Cepeda Javier , Savolainen Panu
Published: January 2025

El discurso teórico desarrollado por Raili y Reima Pietilä en la década de los sesenta sobre el carácter morfológico de la arquitectura radicó en un interés por los componentes naturales y el contexto, con proyectos fuertemente vinculados al paisaje tanto física como culturalmente. En esta ocasión, este artículo se centra en el conjunto residencial Suvikumpu (1962-82), el cual fue opacado por otros proyectos coetáneos que tuvieron mayor repercusión; sin embargo, sirve como paradigma de dichos intereses. Este proyecto reafirmó los intereses teóricos mostrados en proyectos anteriores, permitiendo comprobar su puesta en obra y realidad constructiva. Además de suplir la falta de documentación de los estudios previos, el presente texto pretende mostrar la importancia de la realidad constructiva del detalle arquitectónico del proyecto, usualmente obviado en los análisis realizados de sus obras, siendo la herramienta con la que se materializan las reflexiones teóricas que han caracterizado la trayectoria arquitectónica de los Pietilä.

Published: January 2025

La Estación de Servicio CAMPSA de Huelva (1955-1959), obra de Alejandro Herrero Ayllón, está protegida a nivel autonómico y municipal, e incluida en DOCOMOMO Ibérico. A pesar de su relevancia, carece de un estudio monográfico sobre su proceso de diseño. Esta investigación, basada en documentos originales y parcialmente inéditos, revela decisiones clave del proyecto, como la estratégica elección del emplazamiento, colindante con el ensanche urbano y principales accesos a la ciudad, así como su formalización estructural, con objetivos de alcance urbano, le confiere un valor singular. La configuración triangular y aislada de la parcela permitiría al arquitecto aplicar sus teorías de separación de circulaciones y articular accesos en sus tres vértices. El núcleo central recibe audaces marquesinas de hormigón armado y una torre que consolidan este hito urbano integrado en el paisaje. Por último, se exploran intercambios epistolares entre Herrero y Félix Candela que sugerían una deseada colaboración.

Italian Law No. 116/2021 highlights the necessity of basic life support (BLS) education in schools, especially for secondary school students. This study assessed the efficacy of two basic life support and defibrillation (BLSD) training models — standard teaching method (SE) and mass teaching method (ME) — focusing on student satisfaction and skill retention. Between January 2023 and April 2024, high school students attended either SE sessions (24 students per session) or ME sessions (100 students per session). Both groups completed a 5-hour course following Italian Resuscitation Council Guidelines with an instructor-student ratio of 1:6. Skill retention was assessed immediately and after four months; satisfaction was measured via the Likert scale. Among 1307 students, 899 completed the follow-up. ME students showed superior skill in environmental safety and compression frequency, while SE students excelled in hand placement. Satisfaction levels were high in both groups, with no significant differences, indicating both SE and ME methods were well received.

Bioactivity of plants used traditionally in the treatment and management of men’s sexual health
Authors: Nemandalali Tsumbedzo , Nyila Monde A. , Tshikalange Thilivhali E.
Published: January 2025

Background: In many African societies, men still rely on the long cultural history of utilising medicinal plants to treat and manage their sexual health.Aim: The study evaluated biological activities of 10 ethnobotanically selected medicinal plants.Setting: These plants are used traditionally to treat and manage men’s sexual health in villages under the Thengwe Tribal Authority, Limpopo province.Methods: Acetone extracts were investigated for their antioxidant activity, anti-inflammatory activity against 15-lipoxygenase, inhibition of nitric oxide production on RAW 264.7 macrophages and antimicrobial activity against Neisseria gonorrhoeae and Candida albicans. Phytochemical analysis was performed by determination of total flavonoid and total phenolic content.Results: All the extracts investigated showed moderate to high content of flavonoids and total phenolic content. Cytotoxicity of the extracts was assessed using the XTT reduction assay against Vero monkey kidney cells. Diospyros mespiliformis extract was less toxic and showed significant antioxidant (IC50 = 8.34 µg/mL), anti-inflammatory (IC50 = 63 µg/mL) and antigonococcal (MIC = 0.39 mg/mL) activities. Extracts from Garcinia livingstonei and Rhoicissus tridentata also exhibited promising bioactivity. While these three extracts seem to inhibit the production of nitric oxide, the rest of the extracts seem to promote its production.Conclusion: The findings of the study revealed that the selected plants possess biological activities directly and indirectly associated with men’s sexual health.Contribution: The investigated plants have potential therapeutic effects and can be used as leads in the development of new pharmaceuticals to manage men’s sexual disorders.
Late-onset hypogonadism: current methods of clinical diagnosis and treatment in Japan
Authors: Amano Toshiyasu
Published: January 2025

Testosterone affects several organs in the body and is very important for male well-being. Aging men with late-onset hypogonadism (LOH) experience physiologic, psychiatric, and sexual symptoms related to a decline in the serum concentration of testosterone with age. However, it is well-known that the extent of the decline in testosterone concentration does not correlate with the severity of LOH-related symptoms. Therefore, it is difficult to diagnose and treat patients with LOH. In addition, the symptoms, response to testosterone replacement therapy (TRT), and medical insurance coverage differ among ethnicities and countries. The evaluation of testosterone is essential for the diagnosis and treatment of LOH. The effects of testosterone are determined not only by the serum testosterone concentration but also by the androgen receptor sensitivity. A low number of glutamine repeats is indicative of high androgenic activity, and the number shows ethnicity-related differences (fewer in African American than in Caucasian people and more in East Asian people). The diagnosis of LOH is typically made using subjective symptoms and the serum testosterone concentration. The Aging Male Symptoms scale is widely used to evaluate the symptoms. The normal range of total testosterone concentration varies around the world; therefore, clinicians should follow the guidelines of their regional academic society. The principal treatment for LOH is TRT. There are many types of TRT and other treatment strategies are also available. Thus, physicians should treat LOH according to each patient’s situation, considering related disorders, such as diabetes, osteoporosis, metabolic syndrome, and depression.

This study aimed to analyze the clinical, radiological, and pathological characteristics and treatment modalities of thymoma cases at our institute.

Methods:

This retrospective observational study was conducted at Apollo Hospital, Chennai, from May 2021 to October 2023. Forty-eight patients with thymoma attended during the above period. Their clinical features, radiological, management, and follow-up, were collected and analyzed. After applying the inclusion and exclusion criteria, 43 patients were included in the study.

Results:

Thymoma had more incidence in the age group between 30 and 60 years (58.5%). Incidental finding was the most common initial presentation of thymoma in 41.9% of the participants. The majority of participants with paraneoplastic syndromes (71.4%) had myasthenia gravis (MG). Among the 39 operated patients, 3 (7.6%) had robotic surgery, and the recovery (7 days) was faster than conventional surgery.

Conclusion:

Our study highlights the importance of considering thymoma in patients presenting with anterior mediastinal masses, MG, or incidental findings on imaging. Most thymomas are treatable with minimally invasive techniques, leading to favorable outcomes.
Evaluation of Inhaler Technique in Patients with Asthma and Chronic Obstructive Pulmonary Disease in Andaman and Nicobar Islands – An Observational Study
Authors: Natraj M. , Singh Vishal , Anbarasan T.
Published: January 2025

Objective:

Both asthma and chronic obstructive pulmonary disease (COPD) cause significant morbidity and mortality worldwide. The mainstay treatment for both diseases includes inhalational therapy. A high percentage of patients have symptoms that are not well controlled in spite of using effective medications. One potential reason could be poor inhaler techniques. This results in poor control of the disease along with repeated exacerbations and hospital admissions.

Materials and Methods:

This was an observational study done at the Department of Respiratory Medicine, Andaman and Nicobar Islands Institute of Medical Sciences, Port Blair, Andaman and Nicobar Islands. We enrolled a total of 100 patients who presented to our department during the study period of January 2024 to June 2024. A detailed history was recorded that included questions such as age, sex, disease for which inhalers were prescribed, and the type of inhalers they were using metered dose inhaler (MDI, MDI with spacer, and dry powder inhaler [DPI]). We requested the patients to demonstrate the inhaler technique in the presence of the healthcare professional which was subsequently assessed using a standard validated checklist.

Results:

The majority of the patients were in the age group of 51–70 years of age (55%) with 46% of them being male patients. Fifty-five percent of the patients were diagnosed with COPD while 45% had asthma. Fifty-two percent of the patients were using MDI, 36% were using MDI with space while the remaining 12% of the patients were using DPI. Ninety percent of the patients had a faulty technique.

Conclusion:

The majority of the patients had a faulty technique leading to poor control of the disease. Patients who are using inhaler medications should have their inhaler techniques checked frequently to obtain proper control of their disease.

Abstract

A wide variety of tumors have been described in the pineal region. The occurrence of Medulloblastoma has not been highlighted much, either in the classification or in the diagnostic and management strategies of the posterior third ventricular tumors. We report a case of Pineal Medulloblastoma in a young child which was managed safely and effectively by staged gross-total resection and discuss the surgical and treatment strategies as well as the possible pathological mechanisms associated.
A Case of Isolated Spinal Extradural Extramedullary Acute Myeloid Leukemia: A Rare Cause of Cord Compression in Children
Authors: Gawali Sagar , Agashe Harshwardhan , Purandare Anup , Nayak Naren
Published: January 2025

Abstract

Myeloid sarcoma (also known as granulocytic sarcoma or chloroma) is a rare extramedullary tumor of immature granulocytic or myeloid cells. This can develop into acute myeloid leukemia (AML) or chronic myeloid leukemia (CML). The new term for myeloid sarcoma is extramedullary AML (eAML) tumor. Lymph node is the most commonly involved tissue by eAML. Spinal cord involvement is very rare as an initial presentation without bone marrow involvement. We present a case of 1-year-old male child with spinal myeloid sarcoma presenting with paraplegia. As a spinal myeloid sarcoma causing sudden paraplegia is rare, it may be easily misdiagnosed. Early diagnosis and treatment are possible if the pathology, clinical presentation, magnetic resonance imaging, and histology are known and suspected.

On the unification problem for $\mathrm{GLP}$
Authors: Beklemishev Lev Dmitrievich
Published: January 2025

We show that the polymodal provability logic $\mathrm{GLP}$, in a language with at least two modalities and one variable, has nullary unification type. More specifically, we show that the formula $[1]p$ does not have maximal unifiers, and exhibit an infinite complete set of unifiers for it. Further, we discuss the algorithmic problem of whether a given formula is unifiable in $\mathrm{GLP}$ and remark that this problem has a positive solution. Finally, we state the arithmetical analogues of the unification and admissibility problems for $\mathrm{GLP}$ and formulate a number of open questions.

Authors: Sedka Ilyes , Khellaf Ammar
Published: January 2025

This study focuses on a specific type of nonlinear second-order integral equations defined over a considerable interval. We propose a new numerical method, (T.L.D), in three phases: transformation of the equation, linearization with the Newton-Kantorovich method, and descritization with the Nyström technique. We theoretically define the convergence conditions and illustrate the accuracy of our method on several practical examples.
Multi-Objective Welding Optimization for AA5052 Using Taguchi-Fuzzy
Approach
Authors: Omprakasam S. , Raghu R. , Balaji Ayyanar C.
Published: January 2025

This study investigates the influence of tungsten inert gas (TIG) welding
parameters on the dilution and hardness of AA5052 aluminum alloy. Employing
Taguchi’s L27 orthogonal array, the research systematically explores the effects
of current, voltage, and welding speed. Analysis of the experimental data
utilizes signal-to-noise ratio, analysis of variance (ANOVA), and regression
techniques. The study compares a traditional regression model with a fuzzy logic
approach for result validation, finding that the latter exhibits marginally
better predictive accuracy. Optimal welding parameters are identified as 150 A
current, 20 V voltage, and 45 mm/s welding speed, yielding a maximum dilution of
52.81% and hardness of 145.3 HV 0.5. Current emerges as the most significant
factor influencing both dilution and hardness. Microstructural examination,
hardness profiling, and tensile testing of specimens welded under optimized
conditions reveal a characteristic hardness distribution across the weld zones
and ductile fracture behavior.

Published: January 2025

The objective of this study is to optimize and characterize an Al6061/Al2O3/MWCNT
nanocomposite produced through stir casting. The investigation focused on
various concentrations of 2%, 3%, and 5% by weight of Al2O3/MWCNT nanoparticles,
with an average Al2O3 particle size of 40 nm. The Al6061 matrix exhibited a
uniform distribution of these nanoparticles. Microstructural analysis of the
nanocomposite was conducted using scanning electron microscopy. The study
examined the tribological properties, including wear and coefficient of
friction, as well as the tensile strength and hardness of the Al6061/Al2O3/MWCNT
nanocomposites. The results indicated a significant enhancement in mechanical
properties, with the ultimate tensile strength (UTS) increasing from 122 MPa to
157 MPa, and the yield tensile strength (YTS) rising from 52 MPa to 76 MPa. At a
5% concentration of Al2O3/MWCNT, the hardness test showed an increase from 28
BHN to 55 BHN. The improvement ratios for 2%, 3%, and 5% concentrations of nano
Al2O3/MWCNT particles were 36.54%, 38.51%, and 41.55%, respectively.
Additionally, the study demonstrated that the addition of nano reinforcement
significantly reduced the wear rate. For instance, at a load of 40 N, the wear
rate of the Al6061 alloy was 1.4 x 10-3 mm3/m, whereas it
was reduced to 0.62 x 10-3 mm3/m with the inclusion of 5%
Al2O3/MWCNT nanoparticles.
