THE TOPSIS METHOD FOR EXPERIMENTAL COMPARISON OF MULTIPLE METAHEURISTIC ALGORITHMS OVER A SET OF PROBLEMS: A CASE STUDY OF THE MULTI-CASE CEED PROBLEM
Authors: Arsić Sanela , Gajić Milena , Jevtić Miroljub
Published: December 2024

In recent years, there has been a growing interest in developing new metaheuristic algorithms for optimizing multiple-problems. Due to the stochastic nature of algorithms, their solutions and behaviors are different for different single-problems contained in one multiple-problem. Therefore, in many cases, it is difficult to choose the best algorithm that will solve a specific multiple-problem. This paper uses the multi-criteria decision-making (MCDM) method to rank the proposed algorithms for solving concrete multiple-problem. We take the multi-case Combined economic emission (CEED) problem as a case study. Specifically, we rank five proposed algorithms according to different performance measures using the TOPSIS method to solve four CEED problem cases. Additionally, the obtained results were validated using the EDAS method, confirming the final rank of the analyzed algorithms.
SIMPLE TIME-PHASE/FREQUENCY LOCKED LOOP, FUNCTIONING AS LOW PASS TIME-DIGITAL FILTER
Authors: Perišić Djurdje , Žorić Aleksandar
Published: December 2024

This article describes development, time and frequency analysis, application and simulation of a recursive Time-Phase/Frequency Locked Loop (TP/FLL). The described TP/FLL is based on the measurement and processing of the time-differences between periods of the input and output signals. It may function either as a Phase Locked Loop or a Frequency Locked Loop. TP/FLL is very simple for implementation because it is defined only by one system parameter and one outside control word. Mathematical description, analysis of stability conditions and properties of TP/TFLL are performed using Z transform. Using mathematical analyses and simulations, it is shown that TP/FLL is widely applicable for the phase shifting of pulse signal. Although very simple, TP/FLL naturally possesses the property of low pass digital filter. Special emphasis is given to the analysis and development of a Time-low pass digital filter intended for the filtering of pulse signal periods, using the Mat-lab tools intended for development of classical digital filter.
DEVIATIONS OF ELASTIC GONIOMETRIC MODULE’S CENTER OF ROTATION CAUSED BY LOCATION OF THE APPLIED FORCE
Authors: Komarski Dobri
Published: December 2024

Goniometric elastic stages provide high accuracy angular positioning along one or more rotation axes. One of the main accuracy characteristics is the deviation of the center of rotation. There are many factors that could impact this characteristic like material, geometry and position of the elastic guides, load, position of the applied force for the movement, manufacturing process, etc. As main factor that could have effect on design and accuracy of the elastic module, the position of the applied force e.g. position of the linear actuator and it effect on deviation of the center of rotation is subject of this paper. Based on the finite element analysis, different positions have been studied. These results are important as there are many cases where the position of the applied force can’t be on the optimal theoretical position or there are different deviations during production or assembly that could have impact on the accuracy/deviation of the center of rotation.

PERFORMANCE ANALYSIS OF CHROMA, QDRANT, AND FAISS DATABASES
Authors: Öztürk Emir , Mesut Altan
Published: December 2024

The complexity and dimensions of deep learning models are increasing. Along with the growing complexity, vector databases have been proposed to store high-dimensional data required by the models. Vector databases aim to store high-dimensional vectors and perform similarity calculations on these vectors. In this study, the insertion and query performances of three different vector databases were measured on datasets of varying sizes, and the results were examined. The findings indicate that databases stored in main memory, such as Faiss, provide optimal performance without the need for an index in small-sized datasets and have fast response times. However, as the data size increases, the advantage diminishes with the increasing main memory requirement, and the use of Chroma, which provides index support for disk-stored data, becomes more suitable.

Authors: Mincheva Desislava
Published: December 2024

The article examines the enigmatic world of Thracian mythology and mysteries, immersing itself in hidden messages long shrouded in the mists of time. In this mystical world, the image of Orpheus shines with a magical enigma, concealing unsolved mysteries and hinting at its exceptional role in world history and the spiritual evolution of humanity. According to the Orphics, human nature is a combination of a divine soul and a mortal body, and through rituals and spiritual purification, immortality can be achieved. The purpose of the article is to analyze Orphism as an ancient mystical teaching and explore how it symbolizes the eternal struggle between light and darkness, Good and evil, and what its role is in the context of ancient culture, but also in our modern world. Orphism represents a profound synthesis of philosophy and religion, offering a model for understanding human existence and the contradictory nature of man. The philosophy of Good and evil, illuminated by Orphism, remains relevant today, expressing the eternal aspiration for moral and spiritual elevation.

Authors:   Postdoc Researcher, Technical University of Sofia, Sofia, Bulgaria, Rashid Ekbal , Mastorakis Nikos E. ,   English Language Faculty of Engineering, Technical University of Sofia, Sofia, Bulgaria
Published: December 2024

In this research paper we have attempted to elicit Non-Functional Requirements (NFR) which may or not have been explicitly added to the Request for Proposal (RFP) in housing industry but is important for the success of the program. We have used real time RFPs for the elicitation of NFRs. The sales proposal process, also known as response to RFP process, refers to the methodical steps a vendor takes when developing a proposal in response to a buyer’s RFP which will have details of integrating systems, Software platforms, users, business outcomes, limitations, functional requirements, and may be non-functional requirements (NFR). There is some work done by researchers on assessing opaqueness of NFRs and traceability of NFR. But there has been no work on a complexity scoring model for NFRs which enables a vendor to respond to an RFP with best price and schedule. The paper proposes a novel complexity scoring model for NFRs in RFP in Housing industry by using FURPS (Functionality, Usability, Reliability, Performance, Supportability) quality attribute model in conjunction with MoSCoW(Must Have, Should Have, Could Have, Won’t Have) priority model by using mathematical formula. The working model is broken down in steps for Sales and pre-Sales teams of the Vendor and is ready for adoption.

The ‘Free Lunch Program’ that was promised by Prabowo Subianto and Gibran Rakabuming Raka in their Indonesia’s 2024 presidential election campaign has sparked many controversies and uncertainties amongst the general crowd. In this context, this article will explore several controversial aspects of the program, including large financial challenge, its potential impact on the natural resources, fairness in its distribution, and the worry that this will be nothing more than a mere bluff. The large financial challenge comes from the allocation of the budget for this program, which causes questions on its long term longetivity. Other than that, the impact this program will have on the natural resources, especially in terms of the increasing food demand and its pressure towards our soil and water sources, also causes concerns about the sustainability of nature. The matter of whether it will be distributed evenly is also a matter of concern, with the fear that it won’t reach those who are actually in need. Additionally, the concern of this program being nothing more than a political bluff without any intentions of actually implementing it will also hinder its success. In facing those controversies and uncertainities, it’s important for the government to present a clear and effective plan to implement it, as wll as showing the much needed commitment in running the program properly. With that, this Free Lunch Program kan become an important instrument in increasing the people of Indonesia’s well-being, especially for those who are in need.

Georg Simmel und die Ästhetische Theorie der Architektur
Authors: Borsari Andrea
Published: December 2024

The article is dedicated to the reconstruction and recapitulation of Georg Simmel's relationship to architecture and to the aesthetics of the field of architecture. To this aim, a number of texts have been identified and discussed in Simmel's production that describe the urban dimension, as dimension of the city and of architecture as a modality of the construction of buildings, objects and places to inhabit the world and thus give it a certain configuration. From this discussion derives the plural field of oppositions in relation to the urban-architectural dimension, according to a view of Simmelian thought based on a kind of law of contrast, which can be exemplified in the following set of “oppositional pairs” found in Simmel's work: nature and culture (§ 2), hyperaesthesia and anaesthesia (§ 3), aesthetic “superadditum” and abstraction (§ 4), artistic will and practical functionality (§ 5), connecting and separating (§ 6), transience and eternity or, in architectural terms, temporary and solidity (§ 7), freedom and solitude - subjective culture and objective culture (§ 8). The paper proposes an attempt to trace this series of contrasts and to conclude with an initial assessment of the path traveled and some reflections on a possible convergence between aesthetic and social morphology (§ 9).

Flipped classroom-based application of Peyton’s four-step approach in standardized training of ultrasound residents for thyroid and cervical lymph node zoning
Authors: Wang Jiajia , Zhan Yunyun , Sun Biyun , Bi Yu , Li Rubing , Jiang Fan , Peng Mei
Published: December 2024

Background

To investigate whether combining the flipped classroom approach with Peyton’s four-step method can enhance teaching effectiveness in ultrasound (US) zoning of the thyroid and cervical lymph nodes for standardized residency training.

Methods

A total of 66 resident training students were randomly divided into a control group and an observation group. The control group received traditional teaching methods, including “see one, do one” learning, lecture-based learning (LBL), and case-based learning (CBL). The observation group was taught using Peyton’s four-step teaching method, the flipped classroom approach, and CBL. Assessments were conducted through skill operation and clinical case analysis. A questionnaire survey was used to evaluate student satisfaction. Assessment scores and questionnaire ratings between the two teaching methods were compared.

Results

1) Assessment results demonstrated higher scores in skill operation and clinical case analysis for the observation group compared to the control group [(87.64 ± 3.72) vs. (80.48 ± 5.92) points, (87.94 ± 4.46) vs. (82.85 ± 4.24) points]. 2) The questionnaire survey indicated that resident trainees taught using Peyton’s four-step method showed greater improvement in learning interest [(4.61 ± 0.57) vs. (3.70 ± 0.85) points] and experienced reduced exam pressure compared to the control group [(4.52 ± 0.62) vs. (3.21 ± 0.70) points]. These differences were statistically significant (P < 0.05).

Conclusion

Peyton’s four-step approach combined with the flipped classroom method improved resident training students’ scores in skill operation and clinical case analysis for ultrasound zoning of the thyroid and cervical lymph nodes. It also stimulated learning interest and alleviated exam pressure, making it an effective teaching method for enhancing standardized US training outcomes in resident education.

Si para Octavio Paz la literatura constituye una respuesta a las preguntas que sobre sí misma se hace una sociedad, coincidiendo en este sentido con la ensayista argentina Beatriz Sarlo, para quien “una sociedad habla, entre otros discursos, con el de la literatura”, podría también afirmarse que la literatura, al igual que otras modalidades artísticas, tiene la capacidad de percibir y examinar el “sentir social” y el “espíritu de los tiempos” de una sociedad en un momento histórico determinar, pudiendo presagiar (sin ánimo profético) los nuevos cambios de rumbo que esa sociedad podría experimentar. Este artículo realiza un somero recorrido por algunas representaciones literarias que captaron, de diversas formas, los signos de crispación social que atravesaba a la sociedad chilena y que explotaron en el estallido de octubre del 2019.
Archivo, juegos de espejos, comunalidad y poesía fuera de sí en "Naciste pintada" de Carmen Berenguer: apuntes para una relectura
Authors: Chueca Luis Fernando
Published: December 2024

A veinticinco años de la publicación de "Naciste pintada" de Carmen Berenguer, este artículo propone poner en diálogo las líneas interpretativas más consolidadas sobre este libro con algunas nuevas posibilidades de aproximación. Estas son la importancia de la figura de los juegos de espejos en su configuración textual, el cuestionamiento de los archivos establecidos, la propuesta de archivos alternativos, la comunalidad y la apuesta por la condición de poesía fuera de sí como claves de su carácter híbrido.
Mitología del sótano y carnavalización de la vanguardia: la figura de César Vallejo en la narrativa de Roberto Bolaño
Authors: Vásquez Malva Marina
Published: December 2024

El artículo se propone indagar en las irradiaciones semánticas de la fi gura de César Vallejo en la narrativa de Roberto Bolaño. Desde el enfoque filosófico-arquitectónico de Sloterdijk ‒basado en las metáforas del Palacio de Cristal y del subsuelo de Dostoievski‒, se develan las aristas de una mitología del sótano en “Monsieur Pain” y en “Los detectives salvajes” en su vinculación a una carnavalización de las vanguardias latinoamericanas. Dicha carnavalización se articula como una crítica del “deseo de París” (Darío) de los artistas latinoamericanos, de la razón instrumental de la episteme moderna y del devenir inmunológico o de carácter de “gran invernadero” del mundo globalizado, capitalista.

Authors: Paredes Díaz Sandro
Published: December 2024

Este artículo es un esfuerzo investigativo y divulgativo sobre la poetisa y compositora maulina María Ruiz Martínez (1901-1988). Su objetivo es evidenciar y valorar su labor como editora de la revista “Voces” (1935) a partir del contexto de los estudios sobre las mujeres editoras en la prensa chilena y sus prácticas editoriales en la década del 30, así como su rol dentro del movimiento feminista de la época. Para ello, el texto aborda, en la primera parte, aspectos relevantes de su vida destacando los vínculos con círculos literarios y artísticos contemporáneos. En la segunda parte, realizamos un análisis de algunas secciones de la revista con el fin de verificar la participación de María Ruiz Martínez y valorar su aporte en el contexto de la prensa femenina de la época. El artículo concluye, por una parte, que María Ruiz tuvo un rol importante como editora dentro de la revista y, por otra parte, que la revista recoge una nueva visión sobre la mujer, especialmente soltera, cuyo ideal vivió María Ruiz.
Treinta años de antologías poéticas en Chile (1944-1973)
Authors: Binns Niall
Published: December 2024

El artículo contextualiza y analiza cuarenta y una antologías de poesía chilena publicadas entre 1944 y 1973, partiendo de Poetas chilenos, 1557-1944, de Carlos René Correa, y terminando con la sexta edición de Las cien mejores poesías chilenas de Alone. Estudia la manera en que las antologías dialogan con el canon principal de la poesía chilena, los arduos intentos de renovarlo y la mirada crítica de ciertos antólogos. Después de examinar el papel sumamente marginal de la mujer en las antologías chilenas así como la presencia de temáticas y perspectivas políticas, se centra por último en la figura del antólogo más leído y editado del país: Alone.
Entre el barrio y la ciudad: regeneración del 'Sector Sur Oriente' en torno a
la futura estación de la Línea 9 del Metro en Santiago, Chile
Authors:   , Leiva Lucero Camila
Published: December 2024

La infraestructura de transporte es uno de los aspectos que marca parte de
la planificación y ordenamiento de las ciudades a través de los años, incidiendo
en la calidad de vida de las personas. La expansión de la red de Metro de
Santiago y su influencia en la transformación de la capital es el enfoque de
esta investigación, que desde sus inicios ha tenido un rol importante en la
mejora3t de la conectividad de las periferias con el centro de la ciudad. La
recientemente anunciada Línea 9 de Metro de Santiago, que atravesará la ciudad
por la Avenida Santa Rosa, otorgará a diversas zonas estas oportunidades de
desarrollo que, por medio de una planificación y diseño integral de las
estaciones y del espacio público circundante, se podrían generar lugares
memorables y útiles para satisfacer necesidades específicas de los
territorios.Una de las áreas por donde pasará la nueva línea es el sector Sur
Oriente de la comuna de Santiago, cargada de historia e identidad, pero que ha
sufrido un deterioro progresivo. Se plantea que Metro tiene el potencial de
otorgar incluso a zonas ya consolidadas y antiguas una oportunidad de desarrollo
y reinvención. A partir del estudio de su historia y de sus características
espaciales, se concluye que, por su valor patrimonial, el interés de la
morfología urbana y la activa organización comunitaria es necesario elaborar un
plan de regeneración urbana integrada que permita recibir nuevas estructuras
(como Metro) y, además, potenciar y aprovechar las singularidades del
territorio. Se proyecta un Plan Maestro general de la zona y un proyecto de
estación de escala local que dialogue con las dinámicas territoriales globales y
aporte un espacio de apropiación comunitaria y colectiva para la ciudadanía.
Outflows from tungsten conical wire arrays. Characterization and applications
Authors:   , Muñoz-Cordovez Gonzalo
Published: December 2024

A tungsten conical wire array is used as load in the Llampudken pulsed power generator(∼400 kA in ∼350 ns) to study the outflows produced by it. At pressures of 10 −4 Torrthe dynamics of the wire array is probe by UV/XUV imaging and laser schlieren andinterferometry. These diagnostics show the expulsion of a dense plasma jet (n e = 3 × 10 24m −3 ) of a couple of centimeters in the axial direction above the anode. This plasma jet havevelocities between 10 4 − 10 5 m/s and its dimensionless parameters are computed in orderto compare the experimentally produced plasma jet with the astronomically producedones. At pressures that varies from 10 −5 Torr to 10 −2 Torr the upwards axial emission ofcharged particles is study using negatively biased Faraday cups. At 10 −5 Torr only ionsare detected by the cups but from 10 −4 Torr to 10 −2 Torr the detection of both electronsand ions moving together in the same direction is observed due to the ionization of thebackground gas. Velocity computed for the electrons and ions is in the order of 10 6 m/simplying MeV ions. Finally, the interaction of these outflows with stationary targets isstudy by placing silicon targets at different heights above the conical wire array. Resultsshow that visible damage over the target was observed from 10 cm to 21 cm above thearray where two main damages are appreciated. For targets located closer to the arraymainly micro-pores are observed but for targets located farther from the array stripes-likeformations are appreciated. These damages indicate that the silicon target boiled and wasfastly heated by the conical wire array outflows. Detail measurements of these outflowsand the damages produced on the silicon targets are shown an discussed in this thesis.
Design and experimentation of seismic protection systems for fluid storage
tanks

La protección sísmica de estanques de almacenamiento de líquidos ha sido un
tema poco explorado en el ámbito de la ingeniería estructural. A pesar de que
estas estructuras, ocultas en entornos industriales y sistemas de suministro,
pueden pasar desapercibidas al documentar daños después de un evento sísmico, el
mal comportamiento sísmico de estos estanques puede tener amplias implicaciones
económicas, funcionales y ambientales, entre otras. Los mayores registros de
daños post - sismo se han observado principalmente en estanques de pared
delgada, ampliamente utilizados en la industria alimentaria y de producción de
alcoholes. Los estanques de almacenamiento se dividen en dos categorías
principales: estanques de apoyo continuo y estanques de apoyo en patas. Ambos
tipos han experimentado daños considerables tras eventos sísmicos en países como
Chile, Estados Unidos, Argentina, Italia y Nueva Zelanda. Este estudio se enfocó
en desarrollar sistemas de protección sísmica específicos para ambas tipologías
de estanques, los cuales fueron patentados tanto en Chile como en Estados
Unidos, con patentes ya otorgadas. Para los estanques de apoyo continuo, se ideó
un sistema de anclaje llamado NWSTADAS, que permite el levantamiento controlado
del manto y agrega disipación de energía. Este sistema ofrece control sobre las
cargas transmitidas tanto al manto como a la fundación, siendo aplicable tanto
en estanques nuevos como en la modernización de estanques existentes. Se
realizaron pruebas de laboratorio a los prototipos desarrollados, junto con la
implementación exitosa de estos sistemas en estanques existentes y nuevos, en
colaboración con la industria. Se presenta una metodología de diseño para esta
solución propuesta. Para los estanques de apoyo en patas, se diseñó un sistema
de aislación con auto centrado, basado en la transmisión de la carga axial
mediante patas apoyadas sobre deslizadores planos y un sistema de restitución
elastoplástico denominado columna auto - centrante. Se estudió el comportamiento
de roce de diversos polímeros, poco utilizados en sistemas de aislación
friccional, para ampliar las alternativas de diseño y mejorar las estimaciones
de comportamiento. Se propuso un nuevo modelo de roce que representa de manera
más precisa el comportamiento observado en la campaña experimental, incorporando
fenómenos identificados en la literatura, pero no considerados en los modelos
existentes. Se presenta una metodología de diseño para esta solución propuesta.
Prevalencia del Consumo de Alcohol en Adolescentes en Tres Momentos de la Pandemia y su Relación con el Malestar Emocional
Authors:   , De Las Heras Arretz Santiago
Published: December 2024

El consumo de alcohol en adolescentes chilenos es un importante problema de salud. Aunque el consumo de alcohol ha disminuido en los últimos años, sigue siendo una preocupación en el contexto nacional. Por esa razón, se han implementado medidas de salud pública que buscan restringir el acceso al alcohol las que han sido efectivas. Dada la relevancia que tiene limitar el acceso, es probable que este se haya visto afectado durante la pandemia de COVID-19, las cuarentenas y otras restricciones de movilidad. Sin embargo, estudios previos realizados durante este período reportaron cambios inconsistentes en los patrones de consumo. Pero dado que la mayoría de estos estudios fueron realizados con adultos, no está claro qué ocurrió con el consumo en adolescentes. Esto es particularmente relevante dado el aumento de la molestia psicológica, reportada durante la pandemia, que corresponde a un reconocido factor de riesgo para el consumo de alcohol en esta población. En consecuencia, este estudio evaluó el consumo de alcohol de adolescentes en el contexto pandémico, en tres momentos con restricciones diferentes, y la influencia de la molestia psicológica en este. Se utilizó una submuestra de 914 adolescentes del Estudio Chileno de Crecimiento y Obesidad (ECO), quienes fueron evaluados en tres momentos de la pandemia, con y sin confinamiento. Los resultados indican variaciones en el consumo y su asociación con síntomas de ansiedad, en todas las mediciones y con síntomas depresivos en las dos últimas mediciones. Las restricciones sanitarias se asociaron con una disminución en el consumo. Además, se detectó un aumento en el consumo durante periodos con menores restricciones, como las vacaciones, cuando los adolescentes pudieron socializar más, facilitando así el acceso al alcohol.
