Ajuste de parâmetros do modelo epidemiológico SIR em redes sociais geradas por modelos para simulação da covid-19 em município mineiro
Authors: Cançado Paulo Gabriel Nunes , Vieira Vinícius da Fonseca , Xavier Carolina Ribeiro
Published: July 2024

Devido à pandemia causada pelo coronavírus, o estudo de modelos epidemiológicos tornou-se essencial para a tomada de decisão da população e dos governos. Compreender a dinâmica de propagação do vírus na população possibilita elaborar políticas efetivas de combate à epidemia. Pensando nisso, este trabalho tem como objetivo investigar a propagação do coronavírus na cidade de São João del-Rei. Para isso, foi proposto um algoritmo que utiliza o modelo epidemiológico SIR baseado em redes complexas para simular a propagação do vírus na rede. Os resultados de cada simulação são comparados com dados reais, obtidos no site da Secretaria da Saúde do Estado de Minas Gerais. Por último, os parâmetros β e γ do modelo SIR que representam, respectivamente, a probabilidade de infecção e a probabilidade de recuperação, serão ajustados utilizando um algoritmo genético. Após o término do processo de ajuste, alguns cenários hipotéticos de propagação do coronavírus serão simulados.

Published: July 2024

Mensagens tóxicas acarretam sérios problemas nas plataformas de redes sociais, uma vez que são usadas para prejudicar indivíduos, grupos ou organizações. Os métodos automáticos de combate ao Discurso de Ódio precisam de bons recursos linguísticos, como corpora. A construção manual de corpus de linguagem tóxica impõe desafios significativos devido à forte subjetividade associada ao conceito de Discurso de Ódio e à dificuldade em treinar adequadamente anotadores. A solução deste problema passa pela criação de alternativas para a anotação de dados. Este trabalho apresenta uma técnica semi-supervisionada, baseada em grafo heterogêneo, para detecção e anotação automática de linguagem tóxica. Essa abordagem foi avaliada sobre o corpus ToLD-BR e apresentou nível de concordância moderada com seus rótulos originais.

Seguindo nossa proposta obtivemos: com Random Forest 52 à 92 % de acurácia, 54 à 94 % de AUC, e 61 à 100 % de precisão; com LSTM 61 à 80 % de acurácia, 58 à 78 % de AUC, e 56 à 85 % de precisão.
Stochastic Target Encoder - A new categorical feature encoding applied to urban data regression problems
Authors: Araujo João Victor , Santos Gean da Silva , Aquino Andre L. L. , Queiroz Fabiane
Published: July 2024

Regression problems are Machine Learning (ML) tasks often found in real world, with many attributes being categorical. Most ML algorithms works only with numerical data, so encoding these attributes tends to be necessary, but common encoding methods don’t use data properties, which can lead to poor model performance on high cardinality data. Target Encoding methods address this, but encode each attribute into a discrete set of values of equal cardinality to the categorical attribute. We propose a Target Encoder that addresses both issues introducing variability to encoded data using target statistics, achieving results comparable with the existing Target Encoders. We test our method against existing Encoders, showing the robust performance of our method.

Published: July 2024

We present a novel Natural Language Processing (NLP) pipeline designed to analyze gender bias in Portuguese literary works. Our pipeline comprises five processing steps, culminating in gender bias detection across different linguistic dimensions. We apply it to a corpus of Portuguese literary texts and evaluate its effectiveness in uncovering gender bias. Our findings reveal prevalent gender stereotypes in character descriptions, with female characters often associated with appearance and emotion, while male characters are depicted in terms of social status and personality traits. Furthermore, our analysis of physical traits stereotypes indicates a more equitable representation across genders in such a dimension.

Software Engineering Competency Challenges
Authors: Souza Adriana Silveira de , Oliveira Juliano Lopes de , Paiva Sofia Larissa da Costa , Vasconcelos Alexandre Marcos Lins de
Published: July 2024

Context: Competent practitioners are the most critical factor in accomplishing Software Engineering’s (SE) purpose of building and sustaining high-quality software. Challenges: The demand for competent SE professionals grows faster than academia and industry’s capacity to teach and develop these professionals. There is a discrepancy between the competencies obtained by SE graduates and those required by different domains of the software industry. Conflicts and misuse of SE competency elements and concepts hinder cooperation in the SE community. The simplistic view of human factors related to SE competency hampers its application in SE education, research, and industry communities. Implications: A profound and consensual understanding of SE competency can accelerate SE professionals’ training and direct them to meet the software industry’s needs. Theories and practices based on a uniform construct can improve software quality and increase teams’ productivity.

MAXIMAL CONVERGENCE BY FABER SERIES IN MORREYSMIRNOV CLASSES WITH VARIABLE EXPONENTS
Authors: Burcin Oktay
Published: July 2024

Abstract. In this paper, we assume that 𝐺 is a domain bounded by Γ Dini-smooth curve and R > 1 is the largest number such that a function 𝑓 is analytic inside the level curve Γ𝑅 in the exterior of Γ. By taking the function 𝑓 in the Morrey-Smirnov classesm with variable exponents 𝐸 𝑝(⋅),𝜎(⋅) (𝐺𝑅), we obtain a rate of maximal convergence of the nth partial sums of the Faber series of the function 𝑓 in the uniform norm on the closure of 𝐺. Here the rate of maximal convergence depends on the best approximation number 𝐸𝑛 𝑝(⋅),𝜎(⋅) (𝑓, 𝐺𝑅).
ON A METHOD FOR NUMERICAL SIMULATION OF TWO-PHASE FLOW IN AN OIL RESERVOIR
Authors: Gamzaev Khanlar , Bayramova Nusaba
Published: July 2024

Abstract. The process of two-phase flow of incompressible liquids in an oil reservoir described by a nonlinear system of partial differential equations is considered. Within the framework of this model, the inverse task is set to determine the mode in the mining gallery, according to the specified conditions in the injection gallery. By the method of difference approximation, a discrete analogue of the inverse problem is constructed, implicit with respect to pressure, and explicit with respect to the saturation of the displacing phase. To solve the resulting system of linear difference equations, a computational algorithm based on the decomposition of a system of difference equations with respect to pressure is proposed. The proposed numerical modelling method has been tested on model oil reservoirs

Abstract- From the movement of cars, wind, water, etc. in order to suppress the oscillations in the bridges due to external factors, they place specially shaped cushions between the bridge and the abutment. The choice of the shape of the cushions is also important, and depending on the shape, their reports are also carried out in different ways. In the presented article, the oscillations of a spherical cushion were studied. The displacements of the points of the spherical cushion are determined from the system of Lame equations. A system of inhomogeneous equations was obtained using the Hamilton-Ostrogradsky variation principle. By solving this system, the displacements of the points of the spherical cushion were found. By making the main determinant of the system equal to zero, the frequency equation was obtained and its roots were found by numerical method.

USING A DIRICHLET BOUNDARY CONDITION TO DESIGN AXISYMMETRIC DUCTS FOR INCOMPRESSIBLE ROTATIONAL FLOW
Authors: Vasos Pavlika
Published: July 2024

Abstract. In this paper a numerical algorithm is described for solving the boundary value problem associated with axisymmetric, inviscid, incompressible, rotational (and irrotational) flow in order to obtain duct wall shapes from prescribed wall velocity distributions. The governing equations are formulated in terms of the stream function (x,y) and the function (x,y) as independent variables where for irrotational flow (x,y) can be recognized as the velocity potential function, for rotational flow (x,y) ceases being the velocity potential function but does remain orthogonal to the stream lines. A numerical method based on finite differences on a uniform mesh is employed. The technique described is capable of tackling the so-called inverse problem where the velocity wall distributions are prescribed from which the duct wall shape is calculated, as well as the direct problem where the velocity distribution on the duct walls are calculated from prescribed duct wall shapes. The dependent variable of the governing second order partial differential equation is log ( ) eq where q is the speed of the fluid. Numerical results for the case of the Dirichlet boundary conditions will be given. A downstream condition is prescribed such that cylindrical flow, that is flow which is independent of the axial coordinate, exists
Between Leibniz and Locke
Authors: Thiel Udo ,   Philosophy Documentation Center
Published: July 2024

Charles Bonnet’s account of self-consciousness and personal identity is part of his physiology-based psychology. It is similar to earlier views in some respects, but there are also significant differences. This paper analyzes and contextualizes Bonnet’s comments on the topic in relation to Lockean and Leibnizian strands of thought, pulling together his various remarks into a systematic presentation. Central to Bonnet’s account are his distinctions between (1) the feeling of existence and the concept of existence, (2) memory-based personal identity and reflective personal identity, and (3) first-person and the third-person perspectives on personal identity. By introducing these distinctions and by integrating aspects of several traditions into his own independent position, Bonnet’s contribution constitutes a new and important step in the development of early modern debates about self-consciousness and personal identity.

Poverty Dynamics and Its Drivers in Tanzania: A Lesson to Poverty Reduction Policies
Authors: Mangi Edward ,   The University of Dodoma, Massito John , Moshi Arbogast
Published: July 2024

Poverty has been understood to be dynamic in nature. Some people remain in poverty for long periods, but there are others who periodically move in and out of poverty. Identification of driving factors that are highly related to poverty dynamics is a crucial aspect in formulating successful policies geared at ending poverty. Using a sample of 2177, 3148, and 3182 in 2008, 2010, and 2012, respectively from Tanzania's national panel survey, this study intends to assess the dynamic nature and drivers of poverty in Tanzania, bearing in mind that an effective poverty reduction process requires context-specific knowledge about poverty dynamics. The study adopted the Markov transition matrix equation to assess the nature of poverty dynamics and the Multinomial Logit Model to analyse the determinants of poverty dynamics. The results show that poverty is extremely dynamic in the context of Tanzania. Policy variables such as education, rural-urban settings, household head occupation, electricity connection, and ownership of assets were statistically significant determinants of poverty dynamics in Tanzania. The findings imply that social protection and promotion programmes are critical to ensure inclusiveness in the development process and promote pro-poor growth. Policy makers must also consider the varying nature of poverty and vulnerability in designing policies.
Determinants of Food Inflation in Tanzania: Comparative Analysis Before, During and After Covid-19 Shock
Authors: Mwamkonko Mussa Ally ,   The University of Dodoma, Kulwijila Mary Mussa
Published: July 2024

This study examines determinants of food inflation before, during and after COVID-19 in Tanzania. The study used monthly time series data covering both pre-COVID and post-covid periods. The Chow test was employed to analyze whether the prevalence of the pandemic has influenced food prices. The results reveal that the price of fuel and global food prices account for food inflation in Tanzania. The effects, however, are bigger during and after the pandemic than before the crisis because of COVID-19-induced movement restrictions and lockdowns, which have battered the food supply chain. The study further finds that before the pandemic increase in extended broad money supply and government expenditure in the form of wages and salaries have no significant contribution to food inflation. However, after the pandemic, these accommodative expansionary fiscal and monetary policy measures to restore the economy to equilibrium resulted in inflationary pressure in the country. Moreover, the results show that the national food reserve has no significant effect on food prices, neither before nor after the pandemic. This outcome is partly attributable to the shortage of food caused by drought. Thus, to control food inflation, the government has to increase measures towards reducing fuel prices. These include reducing fuel import duties along with revising the whole fuel importation system. Also, the government needs to inspire its citizens to increase food production through increasing subsidies on agricultural inputs to cut down production costs. This is important to take advantage of high food prices in the international markets while maintaining adequate national food reserves. In addition, both fiscal and monetary authorities need to control public expenditures and money supply in the economy. While the government needs to reduce avoidable and unnecessary government expenditures the BOT has to ensure the growth rate of the money supply does not exceed the expansion of the economy.

Every hotel has the same goal, namely increasing sales of room services at a high percentage level. One way that management can take to achieve a high percentage level is by setting appropriate room prices. The purpose of this research is to find out the calculations for Merapi Merbabu Hotel Bekasi, whether in the process an appropriate calculation of the basic price of service products has been realized, and has taken into account the actual costs absorbed. The type of research used in this research is descriptive qualitative research. Data collection techniques use interviews, observation and documentation. The research results show that the overall calculation using the activity-based costing method for the basic price per room type is understate or below the basic price calculation carried out by the Merapi Merbabu hotel.

Child custody is a very important issue after divorce and receives special attention in the law. In the decision of case no. 2037/Pdt.G/2018/PA.Kng, the Panel of Judges decided to give custody of a five year old child to his father, which was different from what was supposed to be. This attracted the attention of researchers because it contradicts the provisions contained in Article 105 of the Compilation of Islamic Law (KHI) and Law No. 1 of 1974 concerning Marriage Article 41. These articles emphasize that children who have not reached the age of twelve (not yet mumayyiz/point of age where children attain the ability to differentiate between good and evil, right and wrong) should have been given custody to his mother. This research aims to find out the basic considerations of the Panel of Judges as well as the views of Islamic Law and Positive Law regarding granting child custody to fathers after divorce. Qualitative methods were used in this research, using library research and documentation data collection techniques. The research results show the following: 1). The judge's basis for deciding this case used Article 41 of Law no. 1 of 1974 concerning marriage, Article 26 paragraphs (1 and 2) letters (a and b) of Law no. 23 of 2002 concerning Child Protection, as well as Article 156 letters (c) and (d) Compilation of Islamic Law, as well as the Kifayah Al Akhyar Book Juz II page 152. 2). The view of Islamic law regarding the consideration of the panel of judges in deciding the case of granting child custody to the father after divorce, when viewed from the perspective of munakahat jurisprudence, is not in accordance with Islamic law. However, from the maqashid sharia perspective, the Panel of Judges has considerations of muhafazah al-nasl/al-nasb or preserving offspring. The Positive Law view is in accordance with positive law. Even though in making a decision on this case, the Panel of Judges did not consider the order of people entitled to receive child custody as regulated in Article 156 letter (a) of the Compilation of Islamic Law, yet the Panel of Judges used its authority based on Article 41 of Law no. 1 of 1974 concerning marriage

Đặt vấn đề: Hội chứng chuyển hoá (HCCH) được xem là cơ chế bệnh sinh trung tâm trong nhồi máu não và là biểu hiện lâm sàng của kháng insulin. Chỉ số Triglyceride-Glucose (TyG) có liên quan chặt chẽ với kháng insulin. Vì vậy, có thể sử dụng chỉ số TyG để tiên đoán HCCH nếu mối liên quan của nó với HCCH là chặt chẽ. Mục tiêu nghiên cứu: Khảo sát mối liên quan giữa chỉ số TyG và HCCH ở bệnh nhân thiếu máu não thoáng qua (TMNTQ) và nhồi máu não (NMN). Đối tượng và phương pháp nghiên cứu: Nghiên cứu cắt ngang trên 202 bệnh nhân TMNTQ và NMN được chẩn đoán và điều trị tại Bệnh viện Thống Nhất. Số liệu được xử lý bằng phần mềm SPSS 25. Kết quả: Tỷ lệ hội chứng chuyển hoá trên bệnh nhân TMNTQ và NMN là 70.8%. Giá trị trung bình của TyG ở nhóm có HCCH là 9.4 ± 0.7 cao hơn so với nhóm không có HCCH là  8.9± 0.7 với p < 0.001. Với ngưỡng cắt là 8.6 TyG có thể giúp tiên đoán HCCH với độ nhậy là 88.3%, độ đặc hiệu là 41.7% và diện tích dưới đường cong là 0.694. Kết luận: Tỷ lệ HCCH trên bệnh nhân TMNTQ và NMN là khá cao. Chỉ số TyG có thể là chỉ dấu sinh học tiềm năng nhằm sàng lọc HCCH trên những bệnh nhân TMNTQ và NMN.
