An In-Depth Study Of Machine Learning In Artificial Intelligence
Authors: Kumar K. Jeevan , Jairam K. , Ambedkar Ch.
Published: August 2024

Machine learning is a branch of artificial intelligence that enables algorithms to uncover hidden patterns within datasets, allowing them to make predictions on new, similar data without explicit programming for each task. Traditional machine learning combines data with statistical tools to predict outputs, yielding actionable insights. This technology finds applications in diverse fields such as image and speech recognition, natural language processing, recommendation systems, fraud detection, portfolio optimization, and automating tasks. For instance, recommender systems use historical data to personalize suggestions. Netflix, for example, employs collaborative and content-based filtering to recommend movies and TV shows based on user viewing history, ratings, and genre preferences. Reinforcement learning further enhances these systems by enabling agents to make decisions based on environmental feedback, continually refining recommendations. Machine learning’s impact extends to autonomous vehicles, drones, and robots, enhancing their adaptability in dynamic environments. This approach marks a breakthrough where machines learn from data examples to generate accurate outcomes, closely intertwined with data mining and data science.

«Como animais ungidos e empalhados na postura duma cópula ou duma presa comum a consumar»: Entre a incompreensão do outro e a potência de ser diferente
Authors: Almeida Andreia
Published: August 2024

In the novel Maina Mendes, by Maria Velho da Costa, some female characters are repeatedly compared to animals. In this essay, we make a survey of some of these approximations between women and animals, seeking to reflect on their association with Maina and Cecily’s search for freedom, and their consequent resistance to the traditional role of women. This reflection is made within the scope of some feminist texts, using the concepts of Subject and Other, seeking the affirmation of difference through the creation of other ways of being, despite the incomprehension, and the consequent threat, that difference can cause in the patriarchal society.
Feridas Coloniais: Uma discussão sobre a escrita literária coletiva como reparação pós-colonial
Authors: Rendeiro Margarida
Published: August 2024

This article examines texts written by Afrodescendant women published in the collective anthologies Djidiu: A herança do ouvido (2017) and Volta para a tua terra (2021, 2022) to argue that (1) when struggling against «displacement» as a collective experience, writing partakes a transnational process of reparation to decolonize persistent forms of coloniality of power and being in the Luso-Afro-Brazilian space (Mignolo, 2017); (2) they inscribe their right to subjectivity, actively rewriting narratives on (non-)belonging to a society that has underestimated its inherent plurality.
A review on the application of the boundary element method for solving acoustic eigenvalues in infinite media
Authors: Loeffler Carlos Friedrich
Published: August 2024

Vibration analysis is fundamental in the analysis and design of rotating machinery designs, such as turbines, pumps and bearings. It is equally important in the theory of sound and is also related to the properties of electromagnetic waveguides. Its application extends to vehicle structures, equipment and design machines, both for reference and comfort. However, a vibrational analysis also has more daring purposes, directed to the definition of seismic attributes, to the dispersion of phenomena related to acoustics in infinite media. This solution can be adapted as the frequency of vibrations and how outdoor environments are designed for self-balancing devices are designed for Helmholtz self-balancing devices, which are directly adjusted. Typical pressure media situations, Boundary Element Method (BEM) is considered as one of the technical circumstances or more considered, due to its pressure field accuracy, especially differentiated by barriers and scattering of general circumstances, whose frequencies are complex numbers. This work aims to present the various particularities of BEM in approaching these problems, which involve determining the acoustic eigenvalues in open and closed domains, highlighting its operational advantages and numerical difficulties.
Three-dimensional quasi-umbilical locally strongly convex homogeneous affine hypersurfaces
Authors: Chikh-Salah Abdelouahab , Amini Iman
Published: August 2024

The study of strongly convex, locally homogeneous hypersurfaces in the affine space ℝn+1 has a rich history. In dimension 2, these hypersurfaces were first examined in Guggenheimer's 1977 book “Differential Geometry” [4], and the classification was completed by Nomizu and Sasaki in their 1991 paper “A new model of unimodular-affinely homogeneous surfaces” [6]. Apart from the work of Magid and Vrancken in their 1995 paper [5] and Ooguri’s 2013 paper [9], most studies have focused on locally strongly convex affine hypersurfaces. These are characterized by an induced affine metric that is positive definite, and have been extensively studied in Sasaki’s 1980 paper “Hyperbolic affine hyperspheres” [10]. When the hypersurface is an affine sphere, where the shape operator has all eigenvalues equal to zero, Dillen and Vrancken provided a complete classification in a series of papers. In dimension 3, their 1993 paper “The classification of 3-dimensional locally strongly convex homogeneous affine hypersurfaces” [3] offers a comprehensive classification for any dimensions of eigenvalues of the shape operator. In dimension 4, the quasi-umbilical case was explored by Dillen and Vrancken in their 1994 paper “Quasi-umbilical, locally strongly convex homogeneous affine hypersurfaces” [2]. The case where the affine shape operator has two distinct eigenvalues, each with a multiplicity of two, was investigated by Chikh-Salah and Vrancken in their 2017 paper “Four-dimensional locally strongly convex homogeneous affine hypersurfaces” [1]. In this paper, we provide a different proof of the final theorem in Dillen and Vrancken’s [3], utilizing Mathematica software to calculate all Christoffel symbol functions.

Published: August 2024

This study investigates vegetation ecology and rangeland degradation in the arid and desert regions of northeastern Algeria from 2015 to 2023, with predictions extending to 2031. Utilizing remote sensing techniques, specifically Landsat 8 and Landsat 9 imagery, and the Modified Soil Adjusted Vegetation Index (MSAVI), we mapped and analyzed changes in vegetation cover. The QGIS MOLUSCE plugin facilitated spatiotemporal analysis, revealing significant natural and anthropogenic impacts on a study area. Less degraded rangelands have also seen an increase, from 44,110,116 hectares in 2015 to 48,481,851 hectares in 2023, due to drought, overgrazing, and socioeconomic pressures. With a slight decrease to 48,450,495 hectares projected for 2031. This suggests efforts in land rehabilitation and sustainable rangeland management are yielding positive results, though there remains room for improvement. The study recorded that Agricultural croplands have experienced a slight decrease from 1,404,153 hectares in 2015 to 1,350,693 hectares in 2023. However, a modest increase to 1,587,242 hectares is projected by 2031. The findings indicate that Oases date palm areas have increased from 1,287,342 hectares in 2015 to 1,630,197 hectares in 2023, with further growth to 1,816,296 hectares anticipated by 2031. Our research highlights the critical role of remote sensing in monitoring vegetation dynamics within arid and desert ecosystems. The methodology provides a robust framework for similar studies, emphasizing the necessity for ongoing monitoring using advanced télédétection technologies. To mitigate further degradation and preserve these fragile ecosystems, the implementation of sustainable land management practices is essential.
A comparative study of the Zeigler-Nickols PID, and fuzzy-PID based speed controller BLDC motor
Authors: Rahoua Naima , Mechgoug Raihane , Tkouti Nacira
Published: August 2024

Because of their effectiveness, simplicity, and polyvalence, PID controllers are widely used in industrial applications. Within the field of electric motors, namely the brushless direct current motors (BLDC). To maximize the performance of BLDC motors, which are known for their dependability and efficiency, precise speed control is essential. PID must be adjusted each time they are used in an application in order to maximize performance. In this study, we presented a comparison between two PID controllers for Brushless DC motors (BLDC). The first suggested PID controller is based on the Ziegler-Nichols method, a well-known empirical adjustment and testing strategy, resulting in under optimal performance in the presence of optimum local solutions for large research spaces. The fuzzy inference system is used to adjust the controller parameters in the second PID controller. The performance with the proposed Zigler-PID and fuzzy- PID controllers is analyzed and compared using the developed MATLAB/simulink model. These results demonstrate the effectiveness of Fuzzy –PID in improving the precision of speed control and energy efficiency.

Published: August 2024

Our work is pointed toward planning a device for estimating all out solar radiation in light of a reference photovoltaic cell. The rule of this device is chiefly founded qualities of a photovoltaic cell where sun oriented radiation is corresponding to the short circuit current, wich is estimated by a resistor.The voltage difference at these connections is measured by acquisition using a functional amplifier and then recorded into an analogue-to-digital converter for further processing. The Arduino Uno platform was chosen to process and display in real-time the solar radiation received from the reference cell surface. The affordable device has a wide range of uses, including monitoring solar radiation in both stand-alone and grid-connected photovoltaic power plants. The decision to utilize the Proteus design software environment has proven to be a key factor in the successful testing and validation of the device's performance. This integrated platform has enabled the efficient implementation and simulation of the hardware and software components, ultimately leading to the development of a cost-effective and reliable solar radiation estimation solution.

Durante a pandemia, as hospitalizações por transtornos neuróticos e relacionados ao estresse emergiram como um aspecto crucial da resposta global à crise de saúde pública. A pandemia não apenas exacerbou os desafios físicos de saúde, mas também teve um impacto significativo na saúde mental. Neste contexto, explorar a incidência das hospitalizações não apenas ilumina a gravidade do problema, mas também delineia caminhos para melhorar a gestão e o tratamento dessa condição debilitante. O objetivo deste trabalho foi analisar a influência da COVID-19 nas internações causadas por transtornos neuróticos e relacionados ao estresse no Brasil. Este é um estudo de séries temporais, que usou dados do Sistema de Informações Hospitalares (SIH). Demostramos um aumento de 27% nas internações, com o sudeste sendo responsável pela maioria das internações. Além disso, identificamos que mulheres brancas, com 20 a 29 anos foram as principais afetadas. A pandemia trouxe consigo uma carga adicional de estresse, incerteza e mudanças drásticas no estilo de vida, todos os quais podem ter exacerbado sintomas de ansiedade, depressão e outros transtornos mentais. As internações podem ter sido influenciadas por múltiplos fatores, incluindo o isolamento social, medo da infecção, perda de entes queridos, pressões econômicas e dificuldades no acesso aos serviços de saúde. A necessidade de cuidados e o manejo de crises podem ter sido agravados pela interrupção de serviços de apoio comunitário e de saúde mental. Compreender esses padrões não apenas fornece informações cruciais sobre o impacto psicológico da crise sanitária, mas também orienta estratégias para melhorar o suporte emocional.

As doenças periodontais são prevalentes e possuem um impacto significativo na saúde geral, estando fortemente associadas a diversas condições sistêmicas, incluindo doenças cardiovasculares. Este estudo tem como objetivo realizar uma revisão sistemática da literatura para delinear a inter-relação entre doenças periodontais e problemas cardiovasculares, destacando os mecanismos biológicos comuns e as implicações clínicas. A justificativa para a pesquisa reside na crescente evidência de que a saúde bucal e a saúde cardiovascular estão intimamente ligadas, o que pode levar ao desenvolvimento de estratégias preventivas e terapêuticas mais eficazes. A metodologia seguiu as recomendações do PRISMA, utilizando a estratégia PICO para formular a pergunta norteadora. Foram selecionados 20 artigos das bases de dados PubMed, Scopus, Web of Science, Blackwell, Science Direct, SciELO e Ovid, publicados entre 2011 e 2024. Os resultados indicam uma forte ligação entre doenças periodontais e cardiovasculares, com a inflamação sistêmica emergindo como um mecanismo central nessa conexão. Estudos mostram que a terapia periodontal pode reduzir marcadores de risco cardiovascular e melhorar parâmetros clínicos. A revisão destaca a necessidade de uma abordagem integrada na gestão da saúde bucal e sistêmica. Em conclusão, a saúde periodontal é crucial para a prevenção de complicações cardiovasculares. Estudos futuros devem explorar mais profundamente os mecanismos biológicos dessa inter-relação e investigar a eficácia de diferentes intervenções periodontais em diversas populações. Pesquisas longitudinais também são necessárias para estabelecer causalidade e fornecer dados robustos para guiar a prática clínica integrada.
A hospitalidade em Emmanuel Levinas: um chamado ético à responsabilidade pelo outro
Authors: Maslowski Adriano André , Mallmann Gabriel
Published: August 2024

Este artigo propõe uma análise da concepção do termo da hospitalidade na filosofia de Emmanuel Levinas, explorando como ela se manifesta como um imperativo ético fundamental em sua obra. A proposta filosófica de Levinas apresenta a hospitalidade emergindo a partir da relação com o outro. Ou seja, na relação subjetiva com o outro, há um clamor, um convite do qual emerge a responsabilidade ética para com outrem. Nesse aspecto, o pensamento do autor é um convite a pensar o próprio modo de constituição do pensamento, sendo assim um convite a não partir do mesmo, mas sim a partir da própria constituição da subjetividade dada na relação com o outro. Portanto, a proposta do artigo discorre através de uma abordagem filosófica o pensamento de Levinas, buscando observar alguns elementos do significado da hospitalidade em Levinas, sua relação com a ética da alteridade e sua relevância para os desafios contemporâneos da convivência humana.

Oleh karena itu, perlu dilakukan kajian mendalam tentang bagaimana pembelajaran IPAS yang diferensiasi dilaksanakan dan dampaknya pada pembelajaran deskriptif. Pengumpulan data dilakukan melalui wawancara, dengan menggunakan lembar pedoman wawancara sebagai instrumen penelitian. Data yang terkumpul dianalisis menggunakan teknik analisis data yang meliputi reduksi data, penyajian data, dan verifikasi. Berdasarkan hasil analisis data, terdapat beberapa tahapan yang harus dipenuhi dalam pembelajaran IPAS yang berdiferensiasi. Tahapan tersebut mencakup pemetaan kebutuhan murid melalui asesmen non-kognitif, perencanaan pembelajaran yang disesuaikan dengan kebutuhan individu, serta evaluasi dan refleksi terhadap proses pembelajaran. Penerapan pembelajaran IPAS yang berdiferensiasi memberikan dampak positif bagi murid, seperti peningkatan semangat dan antusiasme selama pembelajaran berlangsung.

Abstract— The continuously operating reference station (CORS) that provides a Global Navigation Satellite System (GNSS) enables precise location and height data for various applications such as site selection of important engineering projects and constructions and hazard analysis.  Similarly, the most common applications of the CORS network, in Bhutan, are for engineering, cadastral, geodetic, and topographical surveys.  In this regard, the consistency and dependability of the data from the CORS station are crucial. Moreover, the ability of such applications heavily depends on precise and reliable data from the CORS network. However, Bhutan has not conducted any studies on the stability, in terms of its position, and height fluctuation of the CORS station. Therefore, the goal of this study is to determine the positional and height variation of the 9 CORS stations that are operational in Bhutan between the years 2016 to 2022. Assessing the stability and dynamic behavior of reference stations in a CORS network is part of position variation analysis. It is feasible to identify and quantify a variety of geodetic occurrences by examining the time series of positional analysis. Analysis of height variation focuses on changes in orthometric heights throughout the CORS network. In our study, all the available GNSS CORS data are processed and the displacement in height and position is computed and compared. The analysis consists of a simple method (mean value subtraction) of time series data, which is computed and compared.  The major findings show that the absolute mean standard deviation in the position of the stations was 5.49 cm, 6.36 cm, and 4.24 cm vertical (height), ease, and north horizontal component respectively. The findings highlight that the proposed method of determining the variation in height and location of the CORS stations is fairly practical and will help the user community to guide them in using the CORS network across Bhutan wisely. Similarly, the result of this study will be a relevant source of information to organizations such as the National Land Commission Secretariat (NLCS) as a means to augment the system in the future.

The barcode system is used to automate data collection and is valuable to eliminate the possibility of human error, and the data obtained through the barcode is generated rapidly. Further, barcode scanning automatically enters a large amount of data into a system, making it efficient for recordkeeping and streamlining the records. Previously, Jigme Namgyel Engineering College (JNEC), had a paper-based registration system. It generated a great deal of paper, and time was consumed in long queues while students entered and exited the campus. Therefore, a QR system was developed whereby users scan outgoing/incoming QR through Google scanners and fill an online form. The system was also found to be time-consuming as the user had to punch in details manually and there was also a need for an internet connection. Although the system did help curb paper wastage. Therefore, to overcome the limitations of both systems, a Barcode System has been developed, wherein the barcode present in the user ID card is scanned and the user details will be auto-generated in the system. This system was developed and designed using Microsoft Access (MS Access). Problem-Based Learning (PBL) methodology was also implemented along with the System Development Life Cycle (SDLC). The system allows users to view and print the user record based on department. Generate users’ entry and exit reports, and also sort the report by date. The Barcode system is found to be the quickest and easiest way for the user to get registered. It is essential because it fulfills the primary role of keeping the record of outgoing or incoming users faster and easier. The Barcode system also fulfills the aim of going green by reducing paper wastage.
