Authors: Steyer Fábio Augusto , Rosa Francielly da
Published: January 2024

Neste estudo, analisamos os processos de (des)rostificação da boa mulher por meio do estudo comparativo entre duas narrativas: o conto Amor de Clarice Lispector, focando na protagonista Ana, e o romance Dias de abandono, de Elena Ferrante, analisando a personagem Olga. Investigamos o espaço do feminino nas narrativas, o desenvolvimento psicológico das protagonistas e a ocorrência do movimento que culmina em um rompimento das linhas molares, além da desconstrução do rosto da mulher exemplar. Para isso, utilizamos os conceitos de rostidade e das diferentes linhas de segmentaridade, propostos por Deleuze e Guattari (1996a; 1996b). Também nos embasamos nos escritos de Simone Beauvoir (1970), entre outras autoras relacionadas ao objeto de estudo.

Este artigo procura fazer uma análise da descrição do espaço em obras de José de Alencar, Iracema e O Guarani, demonstrando a importância da afetividade na construção das cenas e da subjetividade na interpretação das intersecções entre personagens e natureza. Para isso, será considerada a obra A poética do espaço, de Gaston Bachelard, como forma de entender a paisagem paradisíaca e a construção de personagens que são propostas nas obras indianistas. Além disso, também serão analisadas as metáforas presentes nas duas obras, levando em conta o que Bachelard propõe, assim como a ideia do “ninho” como espaço afetivo criado pelas personagens e suas rupturas.
CONVERGÊNCIA E DIVERGÊNCIA ENTRE LINGUAGEM E MENTE EM DIAS DE ABANDONO, DE ELENA FERRANTE
Authors: Silva Cesar Paulo da
Published: January 2024

O objetivo deste artigo é investigar a linguagem utilizada por Elena Ferrante no romance Dias de abandono para retratar as mudanças psíquicas vivenciadas pela protagonista Olga. Ferrante apresenta a jornada emocional de uma mulher abandonada por meio de uma escrita consciente e distante. Tal linguagem transmite a intensidade dos sentimentos de Olga sem recorrer a recursos tradicionais que situariam o psicológico da protagonista em um espaço que, aparentemente, evidenciaria um retrato fiel dos momentos vividos. A pesquisa buscará compreender como essa estratégia estilística de deslocamento psicológico contribui para evidenciar a angústia e a solidão da personagem central. Com base em investigações no próprio texto e referências teóricas pertinentes, almeja-se oferecer novas perspectivas para a compreensão desta narrativa e de sua autora.

Published: January 2024

Fuzzy controllers are a powerful tool for controlling complex processes. However, its robustness capacity remains moderately limited because it loses its property for large ranges of parametric variations. In this paper, the proposed control method is designed, based on a fuzzy adaptive controller used as a remedy for this problem. For increase the robustness of the vector control and to maintain the performance of the five-phase asynchronous machine despite the presence of disturbances (variation of rotor resistance, rotor inertia variations, sudden variations in the load etc.), by applying the method of behaviour model control (BMC). The results of simulation show that the fuzzy adaptive control provides best performance and has a more robustness as the fuzzy (FLC) and as a conventional (PI) controller.
Multilayered Inhomogeneous Beams under Torsion and Bending: An Analytical Study of Energy Dissipation
Authors: RIZOV Victor
Published: January 2024

The present theoretical paper is devoted to the problem of energy dissipation in multilayered inhomogeneous beam structures of visoelastic behaviour. In particular, our attention is concentrated on studying the energy dissipation for the case of a beam that is loaded simultaneously in torsion and bending. Both torsion and bending moments which are applied on the beam change with time so that the angles of twist and rotation of the beam end vary continuously with time. The viscoelastic mechanical behaviour of the beam under torsion is treated by a viscoelastic model that has two linear springs and a linear dashpot. The model is under time-dependent shear stress. The viscoelastic behaviour of the beam under bending is modelled in a similar way. An analytical approach of deriving the energy dissipation is applied. The approach treats a multilayered beam that has an arbitrary number of layers of different thicknesses and material properties. The layers are longitudinally inhomogeneous. An investigation of the energy dissipation is carried-out to clarify the effect of the parameters of the time-dependent bending and torsion moments, the material inhomogeneity and the beam size on the energy dissipation.
The Effects of Technological Aspects on the Formation and Transformation of Cities: The Case of Amman
Authors: ZALLOOM Bushra
Published: January 2024

The contemporary world is dominated by the power of technology and capitalism ideology (called techno-capitalism in this paper). The techno-capitalism transforms various cityscapes worldwide into unsocial hubs for economic purposes and giant realms for play. This transformation weakens social cohesiveness and harms the cityscape by causing poverty, inequality, and a loss of identity, even if it enhances the possibility that the city will enter the global market, and stimulate economic growth as well as innovation. This paper aims to discuss the evolution of cities by studying the reasons behind their continuous dynamics and exploring the influences and effects of techno-capitalism. To achieve the research aims, Amman’s case study will be studied and analyzed to explore the effects of technological and non-technological aspects on the formation and transformation of the cityscape. At the conclusion, the paper will propose some strategies to preserve the uniqueness of the city while keeping up with modern technology.
Comparative Non-Destructive Investigations of the Effects of Structural Changes After Heat Treatment of Carbon Steel Samples by Magnetic Noise and Vibration Methods
Authors: IVANOVA Yonka
Published: January 2024

The microstructure of some components that work for a long time at high temperatures changes, which leads to a reduction in their life cycle. Traditionally, the study of the resulting structures is carried out by mechanical tests and metallographic analysis. The application of non-destructive methods increases the possibilities to monitor the quality of the elements and to prevent destruction. The aim of the study is to detect changes in the microstructure after different heat treatment and ageing heating of materials via magnetic noise and vibration methods. To realize the goal, samples of high-quality medium carbon steel were prepared through targeted heat treatments, quenching and tempering at different temperatures, as well as ageing heating at temperatures of 700 o C for up to 16 hours by vibration and magnetic noise method. The natural frequencies and damping properties of forced longitudinal vibrations of various heat treated steel specimens were obtained and analyzed. Using magnetic noise method, the following parameters were obtained and analyzed: root mean square voltage (RMS), energy and envelope parameters of magnetic noise signals. The comparative application of several non-destructive methods increases the knowledge of methods and materials and makes it possible to establish their sensitivity in studying microstructural characteristics.

Authors: MAAMAR Latroch , AICHA Aissa Bokhtachte , ASMA Toualbıa
Published: January 2024

In addition to the inertial navigation sensors embedded in an autonomous flying robot, Global Navigation Satellite Systems are most often used, in particular, the GPS (Global Positioning System). This offer information with an accuracy that depends on the arrangement of a constellation of satellites. It is very often that a measurement with errors of several meters is delivered by this system. With the need for agile decisions of the autonomous flying robot during its mission, especially in the case of rescuing people during disasters, it is not allowed for uncertainty to reign over the decision of the flying robot. In order to improve the estimators implemented experimentally, a secure laboratory test environment is more preferable. Here, we propose a way that helps researchers to conduct indoor experiments with a pseudo GPS that offers circumstances similar to outdoor navigation. The results that will be discussed are obtained with the Vicon motion tracker laboratory at Aalborg University, Denmark.

Published: January 2024

Chromoly steel is a steel widely used in mechanical manufacturing, it finds many applications for oil and gas, aerospace, and automotive industries. In addition, its ductility, its resistance and its relatively low weight, and its malleability constitute one of the characteristics of choice for the manufacturers. In order to improve the use properties of this steel such as resistance to rupture, corrosion, wear and minimize the risks of fragility, heat treatments are considered in this study. Hence, the objective of this experimental work is to study the effect of heat treatment by quenching followed by tempering at different temperatures on the hardness, structural state, and wear resistance of chromoly steel. In addition, an investigation on the evolution of the rate of bearing surface after friction test was carried out. The results show on the structural level that the sample having undergone quenching followed by tempering at 700°C for 15min, presents a microstructure of globular pearlite with the coalescence of the complex carbides of Mo-Cr-Nb, and a hardness of 226HB. However, regarding the tribological behavior, the sample treated at 600°C recorded an improved wear rate of 49% compared to the sample treated at 550°C. For the wear mechanisms, the abrasive wear mechanism is observed for untreated sample, while the adhesive wear mechanism is dominant for the heat-treated samples. In addition, the rate of the lower bearing surface "Sr2" of this same sample was improved by 2.7% compared to that treated at 550°C.

Authors: ADDOW Yasin Ahmed , ALAS Mustafa
Published: January 2024

This study delves into the utilization of Passenger Car Units (PCU) as a pivotal metric for gauging the influence of diverse vehicle types on traffic flow. Focusing on the context of Mogadishu, data acquisition was conducted across eight key sections of major highways. Employing digital video recorders, the gathered data facilitated a comprehensive analysis of traffic dynamics, thereby enabling the computation of PCU values. The investigation unveiled a discernible trend wherein the traffic makeup, comprising bus, truck, light commercial vehicle (LCV), and car categories exhibited a positive correlation with carriageway width expansion. Nevertheless, the volume composition peaked notably in narrower carriageway widths. Concurrently, the speed of the aforementioned vehicle categories showcased a linear progression proportional to carriageway width augmentation. Intriguingly, PCU values assigned to motorcycles consistently undershot the figures stipulated in the Mogadishu Road Standards (MRS). Conversely, PCU values for bus, truck, and LCV categories consistently surpassed the MRS 2070 benchmarks. This scrutiny distinctly elucidated the intricate interplay between lane width and PCU values across distinct vehicle types, effectively underscoring the propensity of PCU values to escalate with escalating carriageway dimensions.

Among the application of Ad Hoc network we have Vehicular Ad Hoc Network (VANET), which is an important data research domain today. VANET can improve the traffic road efficiency in order to overcome many problems and offer more services to customer. For instance, VANET can lead to reduce traffic jam or improve road safety by minimizing vehicles’ accident. Like any wireless network without infrastructure, the routing task is the most difficult task especially when nodes are mobile. The mobility of nodes, which are vehicles in VANET, causes a rapid change of network topology and leads to bread connection between source and destination nodes. In this paper, we will analyze some routing protocols in order to evaluate their performances. In this study we have proposed some scenarios of VANET routing protocols. The simulation has been done on NS3 simulator and SUMO. Simulation proves that routing protocols have a huge impact on VANET network performances.

Published: January 2024

It has long been proven that radial-shear rolling has a number of advantages over other methods of pressure treatment, which allows obtaining an ultrafine-grained structure, including gradient, in various ferrous and non-ferrous metals and alloys. Therefore, radial-shear rolling plays an important role in the production of high-quality bars with an increased level of properties. This work, carried out within the framework of grant № AP14869135, funded by the Committee of Science of the Ministry of Science and Higher Education of the Republic of Kazakhstan, is devoted to the study of reversible radial-shear rolling of 5KHV2C steel and the identification of its influence on the possible gradient modification of the microstructure of this steel grade. In the course of experimental studies, it was proved that during the deformation of a bar made of 5KHV2C steel with an initial diameter of 36 mm, a gradient microstructure is formed along the cross section of the bar on a radial-shear rolling mill with an extraction equal to 4, i.e. up to a diameter of 18 mm. The cross-section structure of the bar varies from an elongated rolling texture in the central part of the bar to an equiaxed ultrafine-grained microstructure in the peripheral layers of the bar. The gradient character of the microstructure is also confirmed by the distribution of microhardness over the cross section of the bar: microhardness in the peripheral layers of the bar is on average 1.7 times higher than in the central part of the bar.
Influence of the Behaviour Coefficient on the Damage Level of an RC Elevated Tank under Seismic Loading
Authors: OURDIA Ider , HAMMOUM Hocine , KARIMA Bouzelha , ALICHE Amar
Published: January 2024

In Algeria, the seismic design of elevated concrete storage tanks is carried out in accordance with seismic standard, involving a behavior coefficient of the structure. This behaviour coefficient is used to determine the internal forces and to estimate the inelastic deformations undergone by the structure. For the elevated water tank, considered as reverse pendulum structure, this coefficient assumes a constant value (R=2) in the Algerian seismic code. Taking into account a single value, whatever the seismic zone, the site of implantation and the geometric characteristics of the structure, can lead to design errors leading to oversizing, hence an additional cost of the structure. Thus, faced with the need to design resistant structures while minimizing construction costs, it is important to precisely determine the value of this behaviour coefficient to introduce into the evaluation of the structure's response. In this research, the seismic performance of an RC elevated tank is analyzed, using a nonlinear approach based on the Pushover method, initially using the behavior coefficient prescribed by the Algerian seismic code, then secondly using the behavior coefficient approximated by a power-type law, taking into account the seismic zone, the type of soil, the height of the structure and the storage capacity. The results of this study highlight the influence of the value of the behavior coefficient on the seismic performance and the level of damage to an elevated tank.

Authors: SAHIN Yusuf
Published: January 2024

Because of higher specific modulus/strength, lower weight, good corrosion resistance with design flexibility and easy production, carbon fiber reinforced epoxy composites are widely used for many structural applications. Glass woven (plain) and carbon fabric (plain) were studied. Thus, glass fabric-reinforced epoxy composites (GFRCs) and carbon fabric-reinforced composites (CFRCs) were fabricated throughVacuum Assisted Resin Transfer moulding (VARTM) methodology. Firstly, manufacturing unit/control system, preparation stages and some elements used in manufacturing the epoxy based composites are reviewed. Then, effects of stacking sequence of fibers on mechanical properties were investigated and a comparison was made on two types of fabrics on hardness/deformation depth through Stereo Microscope (SM). The experimental results exhibited that the hardnesses measured were around 40.6 HB and 52.4 HRB for GFRP and CFRP, respectively. Improvements in carbon fiber were about 29% in comparison to glass fiber. Further, both hybrid composites made from glass and carbon fiber, the hardnesses values were reduced. In case of C2/G2/C2 hybrid composites, reduction rate was about 9.3% in comparison to C6 fiber reinforced laminate composite. Moreover, it is clearly revealed that there were extensive deformation regions reflecting the white areas because top layer was in G2/C2/G2 samples, but there was no such a white area in C2/G2/C2 composite.
Interaction of Polycarboxylate-Based Water-Reducing Admixture Molecular Structure with Fly Ash Substituted Cementitious Systems: Marsh-Funnel and Mini-Slump Performance
Authors: KOBYA Veysel , MARDANI Ali
Published: January 2024

Polycarboxylate ether-based high-range water-reducing admixtures (PCE) play a crucial role in enhancing the workability of fly ash-substituted cementitious systems. Alterations to the chemical structures of both the main and side chains can particularly enhance the electrostatic repulsion and steric hindrance effects of PCEs. As a consequence, this results in improved performance within cementitious systems containing fly ash substitutions. This study investigated the compatibility of the altered molecular structure of polycarboxylate ether (PCE) with cementitious systems containing fly ash substitutions. To achieve this, five polymers were synthesized, varying the side chain length, molecular weight, main chain length, and main chain lengths of PCEs while maintaining other properties constant. Cement pastes were then prepared using the synthesized PCEs with fly ash replacements at three different rates. Marsh-funnel flow time and mini-slump values were measured in the prepared mixtures. The study revealed that in mixtures without fly ash, PCEs with a long main chain (40k) and short side chain length (1000 g/mole) exhibited the lowest Marsh-funnel flow and mini-slump performance among PCEs with diverse molecular structures. For the other PCEs in these mixtures, the change in molecular structure did not significantly affect their performance. However, as the fly ash replacement rate increased, PCE having a medium main chain (21k) and side chain (2400 g/mole) length outperformed other PCEs in terms of Marsh-funnel flow and mini-slump performance.

Water, an essential resource, has been facing gradual deterioration in quality over an extended period. Water treatment has emerged as a critical concern, with a long-standing acknowledgment of the importance of preserving and appreciating this precious resource. UV-C technology has proven to be an ideal solution that effectively addresses these twin needs. The core principle of UV bactericidal treatment revolves around generating ultraviolet rays within a treatment chamber filled with water. Consequently, ensuring a dependable power source for low-pressure mercury-argon discharge lamps has become imperative to guarantee the efficiency of UV-C disinfection.The primary goal of this study is to supply our discharge lamp with a current source that produces a sinusoidal current at its output, featuring a frequency of 50 kHz and an effective value of 0.65 A. Electronic ballasts enable lamps to enhance radiation quality by operating at high frequencies, and the selection of a power supply is a response to this specific challenge.The aim of this research centers on the utilization of a single-phase matrix converter. The bidirectional switching cells within this converter offer frequency-related advantages. To achieve the desired magnitude and frequency, we employed a PWM control strategy. Subsequently, we implemented a linear current adjustment approach using two controllers: a Proportional-Integral (PI) controller and a Generalized Predictive Control (GPC) in the RST polynomial form. This was done to ensure a high-quality current source with the desired waveform and low Total Harmonic Distortion (THD).The research outcomes have led to environmental simulations conducted using Matlab/Simpower system and Matlab/Simulink.

In this paper, an innovative approach is presented to enhance gear fault diagnosis using the cyclostationarity method. The first part of this study focuses on simulating gear signals under various conditions, allowing exploration of signal characteristics in vibration measurements. Spectral analyses and statistical calculations are performed to extract both classical and cyclostationary indicators. In the second part, the cyclostationarity method is applied to signals recorded at the gearbox bearings, clearly revealing the presence of faults. The results from these experiments demonstrate that cyclostationarity indicators can be leveraged to improve the prediction of signal roughness during the production process. This approach thus opens up new possibilities to enhance the reliability of vibration measurements and refine gear fault diagnosis.
Edición, dedicatorias y relaciones clientelares en la literatura medieval impresa en el siglo XVI: los casos de Juan Tomás Favario y Alonso de Ulloa
Authors: Aranda García Nuria
Published: January 2024

Durante la segunda mitad del siglo XV y la época incunable, las dedicatorias colocadas en los prólogos respondían a una codificación bien definida y basada en relaciones de mecenazgo y patronazgo entre el autor o traductor y el destinatario real del texto. La consolidación de la imprenta y la introducción en este sistema de los nuevos agentes de producción y distribución del libro, especialmente los editores, alteró esta red de relaciones y sus motivaciones, contribuyendo a modificar estos paratextos en los textos medievales reeditados en el siglo XVI. Se pretende mostrar esto último a través de la labor de edición del mercader papelero Juan Tomás Favario y el intelectual Alonso de Ulloa.
"En tanto sol tan atrevida pluma". El poema de "Andrómeda" de Lope de Vega y su función dentro de la estructura de "La Filomena"
Authors: Calvo Florencia
Published: January 2024

En este trabajo presentamos un análisis del poema mitológico “La Andrómeda” de Lope de Vega publicado en 1621 dentro del volumen misceláneo La Filomena. El objeto de este análisis es definir su posible funcionalidad dentro de la dispositio de todo el libro. Para ello prestaremos particular atención a las referencias que dentro de las octavas del poema se refieren a la dedicataria doña Leonor de Pimentel y privilegiaremos una lectura metapoética autorizada por la matriz genérica a la que se adscribe el poema. Desde la premisa que “La Andrómeda” cierra la primera parte de la miscelánea, analizaremos su última octava y para proponer una hipótesis acerca de la metamorfosis final: la del sujeto poético en la figura de Faetón, y sus posibles sentidos hacia la segunda parte del volumen, aquella constituida por la serie de diez epístolas y una elegía.
"Psallentes in cordibus". Canto, conversión y erudición poética en la "Exhortación panegírica al silencio" de Pedro Calderón de la Barca
Authors: Barne Yannick
Published: January 2024

El presente artículo pretende analizar una sección de la “Exhortación panegírica al silencio” de Pedro Calderón de la Barca: el elogio del canto. Se trata de aclarar ciertas dificultades textuales que revelan la complejidad poética y teológica del texto, así como de entender la lógica de conversión que estructura gran parte del encomio. Asimismo, el estudio busca identificar los distintos hipotextos que maneja el poeta para componer su panegírico: el cotejo entre las estancias y los marginalia revela cómo el ethos discursivo del poeta cristiano se relaciona con el carácter híbrido de este magno poema, pues surge de la tensa negociación entre los dos componentes del texto, la poesía y la erudición teológica.
Aproximación a la poesía latina del alicantino Joan Treminyo (siglos XVI-XVII)
Authors: Biosca Bas Antoni
Published: January 2024

La obra del poeta alicantino Joan Treminyo, cuya vida transcurre entre los siglos XVI y XVII, no tuvo apenas repercusión en los siglos posteriores. Sin embargo, su poesía no carece de interés y merece la atención de los especialistas. Sus poemas aparecen en siete libros publicados entre los años 1612 y 1640, aunque hay pruebas de que a finales dels xvi ya escribía poesía. Su obra, de caracter netamente religioso y redactada siempre en latín, forma parte del ambiente intelectual que rodeaba el obispado de Orihuela entre los siglos XVI y XVII.
Chanzas en Arauco. Burla y épica según Alonso de Ercilla
Authors: Gómez Canseco Luis
Published: January 2024

Ercilla otorgó un papel relevante a la burla y la ironía en la articulación de La Araucana. Siguiendo la pauta marcada por Ariosto, el humor se convierte en un instrumento tanto estético como ideológico a la hora de presentar su particular discurso épico ante los lectores y, muy especialmente, ante el monarca Felipe II, interlocutor del poeta a lo largo de toda la obra.
Apuntes para la reconstrucción de la bibliografía del humanista Francisco Núñez de Oria
Authors: Fernández Ríos María
Published: January 2024

Francisco Núñez de Oria, médico y poeta natural de Casarrubios del Monte (Toledo), figura entre los principales autores de medicina de la España aurisecular. Entre su bibliografía encontramos varios tratados divulgativos sobre tocología, higiene y bromatología en lengua vernácula, algunos poemas tanto en latín como en vernáculo, así como una extensa epopeya latina dedicada a Felipe II, los Lyrae Heroycae libri XIV (1581). La obra de este humanista es su mayor legado, trabajos que, aún hoy en día, siguen siendo objeto de estudio, especialmente en el campo de la historia de la medicina. Dada la inexistencia, hasta el momento, de un estudio bibliográfico cabal sobre Francisco Núñez de Oria, en este trabajo nos proponemos arrojar nueva luz sobre la obra de este humanista. Presentaremos, a modo de introducción, una reseña biográfica del humanista, y, a continuación, su bibliografía, estructurada en tres subapartados: obra médica, obra poética y obra perdida.

From the point of view of the lawns' current existence, use and their existence for the future, but the tasks, goals and challenges of grassland management have changed, and in line with this, we have carried out surveys and developed and modified a method for fast and efficient application.

In practice, it is very important to know the quantitative and qualitative characteristics of the forage found in the pasture, as well as the exact economic value of the pasture. The purpose of this study is to present a cheap, fast, reliable and easy-to-apply estimation method.

We took the previous methods into account and corrected and further developed them with the help of recent lawn management research results. Based on our tests, the corrected Balázs method can be used well to estimate the yield of grasslands and to determine the fodder value of the grassland. This method is cheap and requires no technical background. It also has the advantage, based on experience, that it takes into account the preference of species by animals.

The data from the cenological survey and the height measurement of the plant stock can be used to estimate the yield, fodder value and economic value. Being a non-destructive method involving minimal trampling, it is also particularly suitable for monitoring the grassland habitat of protected plants and animals. The method is also presented on a sample example, which proves its applicability.
