Abstract:
An image analysis method has been developed for Sandvik to determine phasecompositions and characteristic length of the binding phase in cubic Boron Nitride(cBN)-composites with low contents of cBN (35-75%).The method consists of taking pictures with a Scanning Electron Microscope,gathering elemental data with X-ray Diffraction (XRD) as well as Energy-dispersiveX-ray Spectroscopy (EDS) and finally using a Matlab program developed for this workto calculate phase compositions and statistical data from the characteristic length ofthe binding phase.Using these methods four different phases were identified in the samples: Blackparticles, most likely made of cBN. A dark gray phase around the black particles, thatconsists of Al-compounds. A light grey binding phase, consisting of TiN or Ti(C,N).Finally there were small traces of white particles which were identified as a product ofabrasive action on cermet milling bodies added during the milling.Mean value, standard deviation and median of the characteristic length of the bindingphase was calculated. For all samples the median value was consistent, sometimeseven being identical for the analyzed sites. This indicates that the binding phase wasevenly distributed across almost all samples.

Abstract:
Apesar de serem intensamente estudados em muitos países que caminham na vanguarda do conhecimento, os métodos sem malha ainda são pouco explorados pelas universidades brasileiras. De modo a gerar uma maior difusão ou, para a maioria, fazer sua introdução, esta dissertação objetiva efetuar o entendimento dos métodos sem malha baseando-se em aplicações atinentes à mecânica dos sólidos. Para tanto, são apresentados os conceitos primários dos métodos sem malha e o seu desenvolvimento histórico desde sua origem no método smooth particle hydrodynamic até o método da partição da unidade, sua forma mais abrangente. Dentro deste contexto, foi investigada detalhadamente a forma mais tradicional dos métodos sem malha: o método de Galerkin sem elementos, e também um método diferenciado: o método de interpolação de ponto. Assim, por meio de aplicações em análises de barras e chapas em estado plano de tensão, são apresentadas as características, virtudes e deficiências desses métodos em comparação aos métodos tradicionais, como o método dos elementos finitos. É realizado ainda um estudo em uma importante área de aplicação dos métodos sem malha, a mecânica da fratura, buscando compreender como é efetuada a representação computacional da trinca, com especialidade, por meio dos critérios de visibilidade e de difração. Utilizando-se esses critérios e os conceitos da mecânica da fratura, é calculado o fator de intensidade de tensão através do conceito da integral J.<br>Meshless are certainly very researched in many countries that are in state of art of scientific knowledge. However these methods are still unknown by many brazilian universities. To create more diffusion or, for many people, to introduce them, this work tries to understand the meshless based on solid mechanic applications. So basic concepts of meshless and its historic development are introduced since its origin, with smooth particle hydrodynamic until partition of unity, its more general form. In this context, most traditional form of meshless was investigated deeply: element free Galerkin method and also another different method: point interpolation method. This way characteristics, advantages and disadvantages, comparing to finite elements methods, are introduced by applications in analyses in bars and plates in state of plane stress. This work still researched an important area of meshless application, fracture mechanical, to understand how a crack is computationally represented, particularly, with visibility and diffraction criterions. By these criterions and using fracture mechanical concepts, stress intensity factor is calculated by J-integral concept.

Abstract:
Neste trabalho é apresentado um estudo dos transistores MOS sem junções (Junctionless Nanowire Transistors - JNTs), cujo foco é a modelagem de suas características elétricas e a análise do funcionamento dos mesmos quanto à tensão de limiar, ponto invariante com a temperatura e operação analógica. Os JNTs possuem uma concentração de dopantes constante da fonte ao dreno sem apresentar gradientes. Eles foram desenvolvidos a fim de se evitar as implantações iônicas de fonte e dreno, que requerem condições rigorosamente controladas para se evitar a difusão de dopantes para o interior do canal em dispositivos de tamanho extremamente reduzido (sub-20 nm). Dessa forma, esses dispositivos permitem um maior escalamento, com um processo de fabricação simplificado. Os trabalhos recentes de modelagem desses transistores consideram dispositivos de canal longo, de forma geral o comprimento utilizado é de 1 µm, de porta dupla ou cilíndricos. Pouco tem sido feito relacionado à modelagem de JNTs porta tripla e a influência da temperatura no funcionamento dos mesmos. Assim, este trabalho tem como objetivo a modelagem do funcionamento dos dispositivos MOS sem junções de porta tripla quanto à tensão de limiar, potencial de superfície, carga de condução e corrente de dreno. Os modelos são derivados da solução da equação de Poisson com as condições de contorno adequadas, apresentando grande concordância com simulações numéricas tridimensionais e com resultados experimentais para dispositivos com comprimento de canal de até 30 nm. No caso do modelo da tensão de limiar, o maior erro obtido entre modelo e simulação foi de 33 mV, que representa uma percentagem menor que 5 %. Também foi apresentado um método de extração da tensão de limiar baseado na igualdade das componentes de deriva e difusão da corrente de dreno. Este método foi igualmente validado com resultados simulados, apresentando um erro máximo de 3 mV (menor que 0,5 %) e aplicado à dispositivos experimentais. A influência da temperatura na tensão de limiar também foi analisada tanto pelo modelo proposto como por simulações e resultados experimentais, mostrando que a dependência da concentração de dopantes ionizados com a temperatura devido à ionização incompleta dos portadores tem grande influência na tensão de limiar. No caso da modelagem da corrente de dreno e do potencial de superfície, foi acrescentada uma correção de efeitos de canal curto. O erro médio foi menor que 12 % para as curvas de corrente e suas derivadas quando comparadas à dos dispositivos experimentais de comprimento de canal de 30 nm. Também foi realizado um estudo do funcionamento dos JNTs, mostrando que o ponto invariante com a temperatura, onde a corrente de dreno se mantém constante independente da temperatura, pode ou não existir nesses dispositivos dependendo da resistência série e de sua dependência com a temperatura. Por fim, a operação analógica dos dispositivos sem junções é analisada para dispositivos de diferentes dimensões.<br>In this work, a study of the Junctionless Nanowire Transistors (JNTs) is presented, focusing their modeling and analyzing their operation. The JNTs are heavily doped devices with a doping concentration constant from source to drain, without presenting doping gradients. They have been developed in order to avoid drain and source ion implantation, which requires rigorous controlled conditions to avoid dopants diffusion into the channel in extremely reduced devices (sub-20 nm). Therefore, these devices provide a higher scalability with a simplified fabrication process. Recent works on junctionless nanowire transistors modeling have considered long-channel (a length of 1 µm is commonly used) double-gate or cylindrical devices. Few works have presented the modeling of triple-gate JNTs and the temperature influence on the device operation. The goal of this work is the modeling of the threshold voltage, surface potential, conduction charge and drain current in triple-gate junctionless nanowire transistors. The models are derived from the solution of the Poisson equation with the appropriate boundary conditions and exhibit a great concordance with three-dimensional numerical simulations and experimental data even for devices with channel length of 30 nm. In the case of the threshold voltage, the higher error obtained between model and simulation was 33 mV, which represents an error lower than 5 %. A method for the threshold voltage extraction based on the equality of the drift and diffusion components of the drain current has also been presented. This method was also validated using simulated results, with a maximum error of 3 mV (lower than 0.5 %), and applied to experimental devices. The influence of the temperature on the threshold voltage has also been analyzed through the proposed model, the numerical simulations and the experimental data. It has been shown that the dependence of the ionized dopant concentration with the temperature due to the incomplete carrier ionization has a great influence on the threshold voltage. In the case of the surface potential and drain current modeling, a correction for the short channel effects has been proposed. The mean error has been lower than 12 % for the drain current curves and their derivatives when compared to the ones of experimental devices with a channel length of 30 nm. An analysis on the operation of the JNTs has been also performed, showing that the zero temperature coefficient point, in which the current is the same independent of the temperature, can or not exist depending on the series resistance and its dependence on the temperature. Finally, the operation of junctionless nanowire transistors in analog applications has been analyzed for devices of different dimensions.

Abstract:
A spectral element algorithm for solution of the incompressible Navier-Stokes and heat transfer equations is developed, with an emphasis on extending the classical conforming Galerkin formulations to nonconforming spectral elements. The new algorithm employs both the Constrained Approximation Method (CAM), and the Mortar Element Method (MEM) for p-and h-type nonconforming elements. Detailed descriptions, and formulation steps for both methods, as well as the performance comparisons between CAM and MEM, are presented. This study fills an important gap in the literature by providing a detailed explanation for treatment of p-and h-type nonconforming interfaces. A comparative eigenvalue spectrum analysis of diffusion and convection operators is provided for CAM and MEM. Effects of consistency errors due to the nonconforming formulations on the convergence of steady and time dependent problems are studied in detail. Incompressible flow solvers that can utilize these nonconforming formulations on both p- and h-type nonconforming grids are developed and validated. Engineering use of the developed solvers are demonstrated by detailed parametric analyses of oscillatory flow forced convection heat transfer in two-dimensional channels.

Abstract:
It has long been known that chronic exposures to high concentrations of respirable coal mine dust can lead to the development of lung diseases such as Coal Worker's Pneumoconiosis, commonly referred to as "black lung", and silicosis. Since the mid-1990s, an alarming resurgence of diseases has been documented in central Appalachia, where underground mining often necessitates significant extraction of rock strata along with the thin seams of coal. These circumstances have prompted concern over if or how changing dust composition might be a factor in contemporary disease prevalence. Until now, the total mass concentration and quartz mass fraction of respirable dust have been regulated and monitored in US coal mines. Unfortunately, however, these two metrics alone do not paint a full picture of dust composition. Earlier work in the author's research group established a preliminary thermogravimetric analysis (TGA) method for coal mine dust. The method is intended to allow estimation of three key mass fractions of the dust from separate sources: coal from the coal strata being mined; non-carbonate minerals from the rock strata being mined or drilled; and carbonates that are primarly sourced from application of rock dust products to the mine floor or ribs. However, accuracy of the preliminary method was substantially limited by poor dust recovery from the fibrous filter media used for sample collection. This thesis includes two studies: The first study aims to establish an improved TGA method. It uses smooth polycarbonate (PC) filters for dust sampling and a modified thermal ramping routine. The method is verified using laboratory-generated respirable dust samples. In the second study, the improved TGA method is used to analyze 75 respirable mine dust samples, collected in 15 US mines. Replicate samples are also analyzed by scanning electron microscopy using energy dispersive X-ray (SEM-EDX). TGA and SEM-EDX results are compared to gain insights regarding the analytical methods and general trends in dust composition within and between mines.<br>Master of Science<br>It has long been known that chronic exposures to excessive respirable coal mine dust can lead to the development of lung diseases such as Coal Worker’s Pneumoconiosis (“Black Lung”) and silicosis. Disease rates in central Appalachia have shown an alarming and unexpected increase since the mid-1990s, despite declining dust concentrations evident from regulatory compliance monitoring data. Clearly, there is a need to better understand coal mine dust composition, which will require additional analytical methods. Thermogravimetric analysis (TGA) has been proposed as one possible method, because it should allow estimation of three key dust components from separate sources: coal from the coal strata being mined; non-carbonate minerals from the rock strata being mined or drilled; and carbonates from application of rock dust products to the mine floor and ribs. However, preliminary work with TGA showed limited accuracy, mostly due to sampling materials. In this thesis, two studies were performed. The first study aims to establish an improved TGA method using smooth, polycarbonate (PC) filters. The second study demonstrates the method on a large number of mine dust samples, and compares the results to those gained by an alternative method that uses electron microscopy.

Abstract:
Afin de prédire le comportement mécanique des matériaux métalliques, il est important de déterminer plusieurs quantités physiques, dont la densité de dislocation qui a un impact majeur sur les propriétés mécaniques. Des travaux récents ont montré qu’il est possible de réaliser ces observations à l’aide d’un microscope électronique à balayage. En effet, cette méthode a l’avantage d’être appliquée sur des échantillons massifs et de permettre l’observation de plus grandes surfaces. Cependant, une étape d’orientation de l’échantillon est nécessaire, et le traitement de l’image est réalisé manuellement. Cela rend l’approche longue et fastidieuse. La méthode R-ECCI est basée sur l’acquisition d’une série d’images à différents angles de rotation et permet d’éviter l’étape d’orientation de l’échantillon. Un profil d’intensité est obtenu, qui est représentatif de la nature du pixel considéré (dislocation, défaut ou matrice). L’objectif de ce projet de thèse était de développer une méthode de caractérisation automatique de la densité de dislocation, en utilisant un algorithme de type clustering appliqué sur les profils. Les images sont traitées de manière automatisée et la densité de dislocation est calculée. La première partie du projet a porté sur le développement de la méthodologie d’acquisition des images et du logiciel de traitement des données et a permis de déterminer les limites et les points forts de la méthode. Dans une deuxième partie, une comparaison quantitative avec les méthodes de mesure existantes (TEM, DRX, HR EBSD ...) a été effectuée. Outre le fait que chacune de ces méthodes ne détecte pas les mêmes populations de dislocations, des résultats complémentaires en termes de limites de détectabilité ont été obtenus. Enfin, les résultats obtenus sur un alliage connu ont été comparés à ceux obtenus par un modèle de prédiction micro-mécanique, et un bon compromis a été trouvé, ce qui permet de valider l’approche globale de R-ECCI<br>In order to predict the mechanical behavior of metallic materials, it is important to determine several physical quantities, including the dislocation density which has a major impact on mechanical properties.

However, a sample orientation step is necessary, and the image processing is done manually. This makes the approach long and tedious.

The images are processed in an automated way and the dislocation density is calculated. The first part of the project focused on the development of the image acquisition methodology and the data processing software and allowed to determine the limits and the strengths of the method. In a second part, a quantitative comparison with existing measurement methods (TEM, DRX, HR EBSD ...) was performed. In addition to the fact that each of these methods does not detect the same populations of dislocations, complementary results in terms of limits of detectability have been obtained. Finally, results obtained on a known alloy were compared to those obtained by a micro-mechanical prediction model, and a good compromise was found, which allows to validate the global approach of R-ECCI

Abstract:
O Método dos Elementos Finitos Generalizados, MEFG, compartilha importantes características dos métodos sem malha. As funções de aproximação do MEFG, atreladas aos pontos nodais, são enriquecidas de modo análogo ao refinamento p realizado no Método das Nuvens hp. Por outro lado, por empregar uma malha de elementos para construir as funções partição da unidade, ele também pode ser entendido como uma forma não convencional do Método dos Elementos Finitos. Neste trabalho, ambas as interpretações são consideradas. Os métodos sem malha, particularmente o Método de Galerkin Livre de Elementos e o Método das Nuvens hp, são introduzidos com o propósito de estabelecer os conceitos fundamentais para a descrição do MEFG. Na seqüência, apresentam-se aplicações numéricas em análise linear e evidenciam-se características que tornam o MEFG interessante para a simulação da propagação de descontinuidades. Após discutir os modelos de dano adotados para representar o comportamento não-linear do material, são introduzidos exemplos de aplicação, inicialmente do Método das Nuvens hp e depois do MEFG, na análise de estruturas de concreto. Os resultados obtidos servem de argumento para a implementação de um procedimento p-adaptativo, particularmente com o MEFG. Propõe-se, então a adaptação do Método dos Resíduos em Elementos Equilibrados à formulação do MEFG. Com vistas ao seu emprego em problemas não-lineares, algumas modificações são introduzidas à formulação do estimador. Mostra-se que a medida obtida para representar o erro, apesar de fundamentada em diversas hipóteses nem sempre possíveis de serem satisfeitas, ainda assim viabiliza a análise não-linear p-adaptativa. Ao final, são enumeradas propostas para a aplicação do MEFG em problemas caracterizados pela propagação de defeitos<br>The Generalized Finite Element Method, GFEM, shares several features with the so called meshless methods. The approximation functions used in the GFEM are associated with nodal points like in meshless methods. In addition, the enrichment of the approximation spaces can be done in the same fashion as in the meshless hp-Cloud method. On the other hand, the partition of unity used in the GFEM is provided by Lagrangian finite element shape functions. Therefore, this method can also be understood as a variation of the Finite Element Method. Indeed, both interpretations of the GFEM are valid and give unique insights into the method. The meshless character of the GFEM justified the investigation of meshless methods in this work. Among them, the Element Free Galerkin Method and the hp-Cloud Method are described aiming to introduce key concepts of the GFEM formulation. Following that, several linear problems are solved using these three methods. Such linear analysis demonstrates several features of the GFEM and its suitability to simulate propagating discontinuities. Next, damage models employed to model the nonlinear behavior of concrete structures are discussed and numerical analysis using the hp-Cloud Method and the GFEM are presented. The results motivate the implementation of a p-adaptive procedure tailored to the GFEM. The technique adopted is the Equilibrated Element Residual Method. The estimator is modified to take into account nonlinear peculiarities of the problems considered. The hypotheses assumed in the definition of the error measure are sometimes violated. Nonetheless, it is shown that the proposed error indicator is effective for the class of p-adaptive nonlinear analysis investigated. Finally, several suggestions are enumerated considering future applications of the GFEM, specially for the simulation of damage and crack propagation

A dificuldade encontrada em acessar os direitos adquiridos legalmente faz com que essa população deixe de usufruir de forma satisfatória dos diferentes segmentos sociais, dentre eles o educacional. As trocas possíveis entre os integrantes do ambiente escolar são percebidas como interessantes para o desenvolvimento dos envolvidos, assim, a interação entre os alunos com e sem deficiência passa a ser percebida como um dos fatores que, se analisados, abrem caminho para a consolidação da inclusão. Percebendo, porém, a disparidade existente sobre a teoria e prática, faz-se necessário perceber, de forma sistematizada, como a realidade se encontra, para tanto, uma ferramenta confiável deve ser utilizada para direcionar caminhos possíveis de atuação. Assim, o presente trabalho teve como objetivo validar um instrumento de pesquisa que analisa a interação entre alunos com e sem deficiência nas aulas de educação física escolar. Para tanto, realizamos dois processos que englobam a validação de um instrumento: a de face e a semântica. Assim, foi solicitado a três professoras estudiosas das áreas de interação, inclusão e educação física escolar para analisar o instrumento e tecer comentários e sugestões sobre os mesmos. Para o passo seguinte foi solicitado aos acadêmicos da área de educação física que aplicassem o instrumento em instituições escolares para buscar a compreensão que os aplicadores teriam com relação ao instrumento. Permeando essa discussão, foi realizado um levantamento sobre os elementos que estão interligados ao processo inclusivo e diretamente relacionados aos itens selecionados para a construção do instrumento avaliativo: a inclusão, o ambiente escolar, atitudes e estratégias do professor, a educação física, a interação entre alunos com deficiência / alunos sem deficiência, alunos / professor. Pode-se perceber que o levantamento realizado referente aos itens anteriormente citados contribuiu para a formulação do instrumento e a percepção da dinâmica e complexidade que o processo inclusivo carrega consigo. O instrumento proposto para avaliar o cotidiano das aulas de educação física e as interações foi, depois do processo de validação semântica, compreendido pelos aplicadores que relacionaram a utilização dessa ferramenta para análise contextualizada das relações corridas durante as aulas observadas.<br>Abstract: It seems that the process of inclusion has been discussed in theory; however it is still distant from the reality of persons with disabilities. The difficulty in accessing the legally acquired rights keeps this population from fully benefiting all the social segments, including the educational. The possible changes among the members of school environment are interesting for the development of all people involved, in a way that the interaction between students with and without disabilities is realized as one of the factors which, if analyzed, open the path to the inclusion consolidation. Despite the clear disparity between theory and practice, it is necessary to realize, in a systematized way, what is the reality like. In order to do that, a reliable tool must be used to direct the possible procedures. Therefore, this dissertation aims to support a research instrument which analyzes the interaction between students with and without disabilities inside the physical education classes. For that reason, we performed two procedures which comprise the validation of an instrument: content and semantics. So we requested three teachers, who are scholars in the areas of interaction, inclusion and physical education, to convey comments and suggestions about these subjects. At the next step, scholars of the physical education area were requested to apply the instrument at schools to seek the comprehension the appliers would have regarding this instrument. Concerning this discussion, a survey was made about the elements connected to the inclusion process and directly related to the selected items to the construction of evaluative instrument: the inclusion, the school environment, teacher's attitudes and strategies, the physical education, the interaction between students with disabilities/students without disabilities, students/teacher. It's possible to realize that the performed survey referring to the previously mentioned items contributed to the instrument formulation and the perception of the dynamics and complexity which the inclusion process carries. The instrument proposed to evaluate the daily physical education classes and the interactions was, after the process of semantics validation, comprehended by the applicants who associated the use of this tool in a contextualized analysis of the relations which occurred during the observed classes.<br>Mestrado<br>Atividade Fisica, Adaptação e Saude<br>Mestre em Educação Física

Abstract:
O objetivo deste trabalho é utilizar o método do tráfego aleatório equivalente para analisar e dimensionar redes ópticas sem comutação para arquitetura de nível único. Uma modelagem analítica, baseada nesse método, que possibilita otimizar os parâmetros da rede considerando padrões mínimos de desempenho é descrita. A rede em estudo utiliza apenas um nó, onde se realizam as funções de roteamento passivo. Em anexo ao nó existem seqüências de conversores de comprimentos de onda gerenciados por um controlador de rede. A estrutura da rede consiste de um certo número de redes ópticas passivas (PONs) conectadas às portas do nó. Essas PONs são distribuídas pela área geográfica onde estão os clientes a serem atendidos. O acesso ao meio constituído pelas PONs é disciplinado por meio da utilização de um esquema WDMA / TDMA administrado pelo controlador de rede. Os comprimentos de onda pertinentes a cada PON conectada a uma porta de entrada do nó são alocados de tal forma que cada um deles se direciona a uma diferente porta de saída e, por conseguinte, a uma diferente PON de destino. Uma conexão entre dois terminais é estabelecida pela seleção de um intervalo de tempo (slot de tempo) pertinente ao comprimento de onda que conecta suas respectivas PONs através do nó. Caso esse comprimento de onda já esteja com sua capacidade plenamente utilizada, conexões adicionais podem ser estabelecidas utilizando-se um comprimento de onda direcionado a uma seqüência de conversores de comprimentos de onda anexa ao nó. Após a conversão, é utilizado outro comprimento de onda que é direcionado pelo nó à PON de destino. A modelagem analítica investigada é utilizada para obter as relações entre os parâmetros da rede, possibilitando a escolha dos seus melhores valores.<br>The purpose of this work is to use the equivalent random traffic method for analysis and dimensioning of switchless optical networks for single-layer architecture. This work reports an analytical model that allows the network dimensioning according to some relevant design parameters and the required system performance. The analyzed network is based on a single node providing passive routing functions. Wavelength converter arrays, controlled by a network controller, are added in the node. The network structure consists of a set of passive optical networks (PONs) connected to the node ports. Those PONs are distributed along the geographical area where the customers to be assisted are. The access to the medium constituted by the PONs is disciplined through the use of a WDMA / TDMA scheme administered by the network controller. The pertinent wavelengths to each PON connected to an input port of the node are allocated in such a way that each one is addressed to a different output port and, consequently, to a different destination PON. A connection between two terminals is set up by the selection of a time slot pertinent to the wavelength that connects its respective PONs through the node. If the capacity of the wavelength is fully used, additional connections can be established by the use of wavelength directed to a wavelength converter array enclosed to the node. After the conversion, another wavelength addressed by the node to the destination PON is used. The connections achieved between the network parameters are detailed to allow the choice of the best network parameters.

Abstract:
AbstractStructural equation modeling is a multivariate data analysis method for analyzing complex relationships among constructs and indicators. To estimate structural equation models, researchers generally draw on two methods: covariance-based SEM (CB-SEM) and partial least squares SEM (PLS-SEM). Whereas CB-SEM is primarily used to confirm theories, PLS represents a causal–predictive approach to SEM that emphasizes prediction in estimating models, whose structures are designed to provide causal explanations. PLS-SEM is also useful for confirming measurement models. This chapter offers a concise overview of PLS-SEM’s key characteristics and discusses the main differences compared to CB-SEM. The chapter also describes considerations when using PLS-SEM and highlights situations that favor its use compared to CB-SEM.

Abstract:
Structural equation modeling (SEM), especially partial least squares path modeling (PLS-PM) has become a mainstream method in many fields of research. In the last years it has been increasingly disseminated in a variety of disciplines. The researchers have been promoting this new statistical methods for the evaluation of policies. Generally, policy evaluation applies evaluation principles and methods to examine the content, implementation or impact of a policy. To better understand and characterize this trend, a bibliometric study of international papers on this subject has been developed in order to describe the use of SEM and PLS-PM approaches in the policy evaluation in the almost last 20 years. A total of 450 articles from 2000 to 2020 have been selected and analyzed in order to discover the research trends in this field and the main dimensions and words related to the terms “decision making” and “SEM-PLS” approach, that are most commonly employed in the scientific literature. The research has been conducted in theWeb of Science from ISI Web of Knowledge database and Scopus database, with the aim of identifying the major themes, authors, areas, types of the sources, titles, years of publication and countries of these publications, as well as the main themes related to the two topic analyzed

Full text
Abstract:
Abstract Different from other types of pipeline solids such as sand and iron carbonates, iron sulfide is semi-conductive and electrochemically reactive. This adds extra complexity to laboratory testing and evaluation compared with inert deposits. Previous laboratory testing has shown that the corrosion rate under iron sulfide deposits can be severely overestimated using electrochemical techniques. In the current work a laboratory iron sulfide synthesis method and an iron sulfide under-deposit corrosion testing methodology were developed to better assess and monitor this type of corrosion in a simulated pipeline environment. Two different types of iron sulfides were used to investigate the corrosion of carbon steel under such deposits. Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD) and laser light extinction particle size analysis were utilized to characterize the surface morphology, composition, crystal structure and particle size of the different iron sulfides. A white light interferometric volume loss method was used to verify the under-deposit corrosion rate continuously monitored by the Linear Polarization Resistance (LPR) technique.

Abstract Scanning electron beams provide a superior method of failure analysis by observing the voltage contrast (VC) both in frontend and back-end processes. Back-end VC tells us both metal/via open/short issues. Front-end VC tells us not only open/short issue but also additional doping information. A case on the application of passive voltage contrast (PVC) on doping information was studied. This paper explains the mechanism producing passive voltage contrast and describes three methods of sample preparation and provides examples of the results achieved.

Abstract:
In recent years, social entrepreneurship has emerged as a powerful solution to various global challenges in the social, environmental, and economic spheres, gaining significant recognition. Promoting this form of entrepreneurship on a global scale is essential. Understanding its determinants has attracted the attention of numerous researchers. To effectively stimulate social entrepreneurship, it is crucial to investigate its determinants, particularly the factors that influence social entrepreneurial intentions. Through a statistical analysis using the PLS-SEM method, this study demonstrates that psychological characteristics, skills, motivations, and conducive environmental factors positively influence social entrepreneurship. Furthermore, mechanisms provided by support organizations for the creation of social enterprises; such as awareness-raising, network integration, access to resources, learning opportunities, and psychological support, play a significant role in shaping intentions through the dimensions of desirability and feasibility.

Abstract:
STEM-education is a modern effective approach that nowadays can be interpreted in very different ways and it even has some modification (STEM/STEAM/STREAM). Anyway, the “New Ukrainian school” concept includes approaches similar to STEM-education. However, there wasn’t analyzed the current state of STEM-education in Ukraine. We propose to analyses it by using SEO analysis of one of the most popular STEM-oriented cloud environment in Ukraine stemua.science. It is proposed to use the cycle for cloud-based educational environments (publishing/SEO analysis/team’s brainstorm/prediction/creation of further plan) to improve their efficiency. It is found, that STEM-based and traditional publications are characterized by similar demand of educational process stakeholders. However, the way how teachers and students found the publication proves that traditional keywords (47.99 %) used significantly more common than STEM keywords (2.67 %). Therefore, it is proved that STEM-methods are less in demand than traditional ones. However, considering the huge positive effect of the STEM method, stemua.science cloud educational environment provides a positive effect on the educational process by including the STEM-aspects during finding traditional approaches of education by stakeholders of the educational process.

Full text
Abstract:
The conventional approach to estimating lake or reservoir water volumes hinges on field data collection; however, volume estimation methods are available that use little or no field data. Two such methods—the simplified V-A-h (volume-area-height) and the power function—were applied to a set of six anthropogenic reservoirs on the Fort Jackson, South Carolina, installation and checked against a validation data set. Additionally, seven interpolation methods were compared for differences in total volume estimation based on sonar data collected at each reservoir. The simplified V-A-h method overestimated reservoir volume more than each technique in the power function method, and the categorical technique underestimated the most reservoir volumes of all three techniques. Each method demonstrates high Vₑᵣᵣ variability among reservoirs, and Vₑᵣᵣ for the Power Function techniques applied here is consistent with that found in previous research in that it is near or less than 30%. Compared with Vₑᵣᵣ in other studies evaluating the simplified V-A-h method, Vₑᵣᵣ in this study was found to be 10%–20% higher.
