Come Hell or High Water: Afterlife as a Poetic Convention in Mediaeval Arabic Literature
Authors: Szombathy Zoltán
Published: February 2024

The Quran contains captivating descriptions of what awaits believers in Heaven and unbelievers in Hell as well as both categories of people at the Last Judgement. Predictably enough, Quran commentaries and the popular imagination would later add further details to such eschatological descriptions. The vivid Quranic imagery of Heaven and Hell and the later elaborations upon this theme inevitably inspired poets and belletrists alike. This study gives an overview of the literary uses of such imagery, including motifs appearing in licentious literature (i.e. the quasi-genre of muǧūn) as a demonstration of wittiness (ẓarf).
Paradise as a Garden, the Garden as Garden
Authors: Bloom Jonathan M.
Published: February 2024

The image of the earthly garden as a foretaste of paradise is one of the strongest and most enduring in the study of Islamic culture. Over the years countless authors have evoked the idea of the verdant garden, with its sensual pleasures of beautiful design, fragrant flowers, luscious fruits, playing fountains and cooling shade, as a counterpart to the delights the believer will encounter in the hereafter. In the last few decades, several books have been written on the subject. There is no reason to believe that the flood of books and exhibitions on this popular theme will cease, but it is worthwhile reexamining the basis for this interpretation of the earthly garden as a metaphor for paradise in Islamic culture.
Animals in Islamic Paradise and Hell
Authors: Canova Giovanni
Published: February 2024

Islam reserves a very different position for animals to that of Christianity, which views animals, having no soul, as existing merely in utilitarian terms for man’s benefit. The article explores classical Islamic sources to present the place of animals in Islamic Paradise and Hell.
’56-os politikai elítéltek „nyugalmat adó menedéke” : Bibó István szakfordító és társai az állami fordítóirodában
Authors: Németh Gabriella
Published: February 2024

This paper not only sets a new framework for the role of political prisoners of the Hungarian Revolution of 1956, who served as language intermediaries for the state, including István Bibó, but also presents the history and operation of the Hungarian Office for Translation and Attestation Ltd. (OFFI) in the same period. The employment of intellectuals, who had been imprisoned and later released through amnesty or upon completion of their prison sentences, as translators is examined from the unique standpoint of their roles as professional translators.The paper also provides insights into the state’s translation orders by the state and the legislative background in the decades under study. This paper does not intend to go into more detail than is necessary for understanding the theoretical aspects of the functioning of the power in the 1950-60-70s, but it may well provide further insights into the subject. The tasks performed by translation trainees and proofreaders at the ‘Bibó Chair’ in the prison of Vác, as well as the actions of the leaders of OFFI at that time, who exhibited solidarity within the limits permitted by the period, continue to have a lasting impact even after six decades. These all point towards the targeted and controlled employment of political prisoners, the creation of a kind of internal Samizdat, and, during the decades after the amnesty, the exploitation of the mental resources of intellectuals, writers, university professors, lawyers and military leaders critical of the regime, as specialist translators for low pay. While, at the same time, the complicity, wit, intelligent humour, camaraderie and loyalty of the political intelligentsia concerned remained still evident.
A fegyelmi ügyek forrásértéke egyes hivatástörténeti kutatásokban, különös tekintettel a bürokráciatörténetre
Authors: Sallai Balázs
Published: February 2024

The main objective of the present study is to provide methodological support for research on the history of professions in which archived sources of disciplinary cases can be used. In order to avoid some methodological pitfalls, an attempt is made to develop a kind of specific paradigm by citing a number of examples from previous research, which may either have a positive or a negative content. In addition to this, the paper deals in detail with the possibilities of demarcating the fields of the history of public administration and the history of bureaucracy from a research perspective, illustrated with examples from Hungarian and foreign literature. The last major section summarises the main directions of research on archival disciplinary files and their significance in the context of a particular scientific research.
Fókuszban a munkafeltételek transzparenciája – Jogharmonizációs kérdések a munka törvénykönyve 2023-as módosítása nyomán
Authors: Zaccaria Márton Leó
Published: February 2024

The present paper focuses on some up-to-date questions of the social policy – in this regard: labour law – of the European Union. To be more precise, the current research is based on the key aspects of the harmonization of laws in this field based on Direc- tive (EU) 2019/1152 on transparent and predictable working conditions. Directive (EU) 2019/1158 on ensuring work-life balance is also mentioned in the paper. The paper analy- ses the directive from the perspective of harmonization of laws, especially the safeguard- ing of the workers’ fundamental rights. The examination is focused on some of the most recent developments in Hungarian labour law that resulted in significant amendments to the Hungarian Labour Code. The paper takes into consideration the general legisla- tive context of the new directives, the most fundamental prescriptions guaranteeing the workers’ rights and lawful interests and especially the new regulations regarding the burden of proof in related labour law disputes. The Hungarian examples are focused on these areas of harmonization emphasizing the new regulations of the prohibition of the wrongful exercise of rights. The findings of the research are summarised at the end of the study paying attention to the possible outcomes and concerns of the new labour law regulations.
Designing a Desktop Application for Ship Monitoring and AIS Data Storage Based on RTL-SDR and Raspberry Pi Using Python and PyQt
Authors: Abiraihan Muhammad , Marta Rizkayeni , Syukhri  , Saputra Hadi Kurnia
Published: February 2024

This research aims to develop a desktop application for Monitoring Ships and storing data from the Automatic Identification System (AIS) utilizing Realtek Software Defined Radio (RTL-SDR) and Raspberry Pi devices. The development method employed is the waterfall model, using Python and PyQt as the main programming languages. Black-box testing was conducted on the application, covering aspects such as decoding AIS messages, real-time monitoring, historical data storage, and statistical analysis of the data. The test results indicate that the application successfully addresses challenges faced by the simple AIS receiver, achieving the research objectives by accurately decoding AIS messages, monitoring ship journeys in real-time, storing AIS data as historical data, and presenting informative statistical data. Despite some lag, especially on the Raspberry Pi device, the application contributes positively with improved accuracy and functionality. Further evaluation, technological updates, and integration with other devices are expected to enhance the application's performance. The use of Python and PyQt provides a foundation for further development to enhance the quality of ship navigation systems. It is recommended to involve the decoding of other AIS message types in future research and to consider building a ship journey simulation system for an interactive user experience.

Published: February 2024

In the present work, a strategy is proposed to control the pulse width modulation signals of the power devices of high switching of a three-phase alternating current to direct current converter as well as the current of a load type RL guaranteeing that the power factor of the supply be the unity, which is achieved by taking advantage of the properties that the complete mathematical model has in the two-phase synchronous frame of reference. Likewise, a formal stability analysis of the complete closed-loop system is presented, thereby demonstrating that the proposed scheme guarantees global asymptotic stability with all bounded internal signals.

Authors:   Universidad de Guanajuato, México, Hernández-Escoto Héctor , Torres Zúñiga Ixbalank ,   Universidad de Guanajuato, México, López-Caamal Fernando ,   Universidad de Guanajuato, México
Published: February 2024

In this work, it is explored a controlled semi-batch operation for a stirred tank reactor in which an enzymatic hydrolysis of cellulose is carried out to enhance the concentration of reducing sugar. A high concentration of reducing sugar impacts fermentation processes in a biorefinery. Cellulose and enzyme feedings are driven by controllers to maintain the highest cellulose concentration allowed by a physical constraint in the process; in consequence, more cellulose is fed than in a typical batch operation and a greater glucose concentration is obtained. The construction of controllers is systematic, and performance is illustrated by simulation.
Improvement of an Algebraic Observer for the Control of a One-Story Building
Authors:   Universidad Autónoma de Coahuila, México, Esquivel Cárdenas Jesús Aureliano , Osuna González Jorge Adrián ,   Universidad Autónoma de Coahuila, México
Published: February 2024

This article presents an improvement to an algebraic observer to estimate the state of a mechanical system whose only feedback variable is acceleration. This problem appears in different mechanical systems, e.g., structures subject to the effects of earthquakes. The algebraic observer that motivates this work is constrained to a finite time range; it cannot observe for time very close to zero, nor beyond a large value, because it would make singular the matrix involved in the estimation. In this proposal these disadvantages are eliminated by obtaining a matrix with independent-of-time determinant. The objective of the observer is to estimate the position and velocity that correspond to the acceleration measure, for use in a recently published control law of the semi-active control system of a single-story building by means of a magnetorheological damper.

Currently, there is a promising therapy to treat cancer that uses dendritic cell infusions. Dendritic cells play a crucial role in the initiation, programming, and regulation of the specific immune response, for this reason they are considered the best antigen-presenting cells. The objective of using them in immunotherapy is to induce a specific immune response of T cells towards cancer cells. This article provides a brief review of three mathematical models of the tumor-immune system interaction subject to dendritic cell immunotherapy. It is important to point out that analyzing mathematical models is a crucial stage in the design of control laws for establishing optimal administration protocols for dendritic cell immunotherapy.

The article focuses on the estimation of a seismic signal in a building-like structure using an adaptive observer. This algorithm allows to estimate to the behavior of the structure based on the accelation measurements, achieving the estimation of uncertain signal. Thus, an adaptive observer is proposed, which estimates both the state and unknown input. The approach is validated by simulating a two-story system using real data from a real earthquake. The results demonstrate the effectiveness of the observer in estimating the displacements in the structure and the unknown seismic signal.

In this work a full-state observer is presented for MIMO linear systems in presence of uncertainties and multiple sampled outputs. The observer is capable to reconstruct the state vector in a continuous form even if it recieves the output in a sampled form. Then, it is possible to establish that the observation error will converge to a bounded value depending on the magnitude of the maximum sampling interval and uncertainties. In the case when there is no uncertainties, the observation error converges to zero. The proposed observer is tested to estimate the state vector in a building structure in which the seismic signal is treated as uncertainty.

Authors:   Instituto Politécnico Nacional, México, González-Sierra Jaime , Flores-Resendiz Juan ,   Universidad Autónoma de Baja California, México, Aranda-Bricaire Eduardo ,   CINVESTAV-IPN, México
Published: February 2024

This work compares two novel strategies that address formation control with collision avoidance for a group of second-order agents. The first control strategy is based on the Backstepping approach (B), while the second is based on the Nested Saturation methodology (NS). Both approaches utilize the Repulsive Vector Fields (RVFs) approach for avoiding collisions. Two numerical simulations are carried out to compare the performance of both approaches. For the first numerical simulation, the simplest case of collision avoidance is considered, that is, the interchange of the position of two agents. On the other hand, for the second numerical simulation, the formation with collision avoidance for a group of nine agents is considered.

Fractional order PI observer for a class of fractional order systems
Authors:   CINVESTAV-IPN, México, Martínez-Guerra Rafael , Oliva Gonzalez Lorenz ,   CINVESTAV-IPN, México
Published: February 2024

Currently the study of fractional order systems has become of great research interest, in particular the state estimation stands out within the lines of studies for this type of systems. Different methodologies have been proposed in order to solve this problem, however most of the techniques involve complete information of the system. Thus, this work presents a methodology for state estimation in a class of fractional order systems based on a fractional order observer which is constructed through an algebraic technique. This observer presents some significant properties, for instance, only variables of interest are estimated, i.e., it is a non redundant observer, it does not need complete information of the system and the initial conditions for the observer can be freely assigned. The stability of this observer is analyzed with the global Mittag-Leffler boundedness approach. Finally, the effectiveness and accuracy of the proposed methodology is verified through state estimation of a fractional-order Duffing chaotic system.
Real-Time Implementation of an Online Controller for the Walking of the NAO Robot
Authors:   Tecnologico Nacional de Mexico/I. T. La Laguna, México, Marquez-Acosta Emanuel , De-León-Gómez Víctor ,   Universidad Autónoma de Coahuila, México, Santibáñez Victor ,   Instituto Tecnológico De La Laguna, México
Published: February 2024

Practical problems for the implementation of a real-time controller for gaits subject to disturbances on the NAO robot are shown in this paper. Moreover, how to deal with them and carry out real-time practical stable walkings is explained. The robot is modeled with the Linear Inverted Pendulum (LIP) model, which is a simplified model that concentrates the mass of the robot in a single point and constrains the height of the Center of Mass to a straight line. The controller in charge of keeping a stable gait is the Model Predictive Controller (MPC). The MPC is perhaps the most used controller in legged robots due to its optimization over a time horizon and to the possibility of including constraints in the optimization problem. Furthermore, important notes about the implementation of real-time experiments with the NAO robot are discussed in this work. This work gives the first steps to achieve a real-time control using the Essential Model.
Decolonizar la educación universitaria: un camino hacia la transformación de la UNERMD
Authors: Pérez Torres Inés Benigna
Published: February 2024

Abstract The objective of this article is referred to reflect on the decolonization of university education in order to transform the UNERMB to the productive process of its communities, in a critical reflection coupled with educational practices that generate formative and creative spaces, assuming for this the approaches of authors like Bigott, capturing reflective postures. It is located in the documentary research modality where theories that allowed discussing the research topic were reviewed. It was used as a methodology to discover ways of interpreting reality from the discourse, applying critical hermeneutics for this and the selected design was transversal, by virtue of its study in a single opportunity. It is concluded that university education remains attached to traditional models with a mechanistic pedagogy that has generated an educational praxis out of step with reality with a passive interaction in the students’ classrooms with their historical-social reality. Hence the importance of eradicating the colonization of education, to give way to the transformation of the university that seeks the emancipation of critical reflective students from their environment, using collaborative work with the IAP to develop an emancipatory critical vision, creating spaces that promote a critical conscience.

Published: February 2024

6102 sayılı Türk Ticaret Kanunu (TTK) ile genel kurul ve yönetim kurulu arasındaki yetki dağılımına ilişkin esaslar, her iki organ için de devredilemez bazı yetkiler bakımından bir sınır çizilmesi (TTK m. 375/1 ve 408/2) ve bunun dışında devredilebilir nitelikteki yetkiler için de yönetim kurulu lehine karine öngörülmesi suretiyle (TTK m. 374/1) belirlenmeye çalışılmıştır. Anonim şirketlerde organlar arasındaki yetki dağılımına ilişkin esaslar gereği, genel kurulun, yönetim kurulu karşısında üst organ niteliği bulunmamakta, genel kurul yönetim kurulunun yetki alanına giren konulara müdahale edememektedir. Bunun dışında her iki organ da kendi yetki alanına giren konularda düzenleme yapma özgürlüğünü haizdir. Bu düzenlemeler normlar hiyerarşisi bakımından esas sözleşmenin altında bulunan genel kurul iç yönergesi ve yönetim kurulu iç yönergesi ile yapılabilir. Keza genel kurul, kendi yetki alanında kalıp genel ve soyut bir düzenlemeye kavuşturulabilecek konuları esas sözleşme değişikliği suretiyle, esas sözleşmede de düzenleyebilir. Peki, genel kurul, yönetim kurulunun yetki alanında kalan konuları, esas sözleşme değişikliği yapmak suretiyle esas sözleşmede düzenleyebilir mi? Yoksa bu konularda düzenleme yapma yetkisi münhasıran yönetim kuruluna ait olup, ilgili düzenlemeler ancak yönetim kurulu iç yönergesinde mi yer bulabilir? Nihayet, kuruluştaki esas sözleşme hükümleri, genel kurul tarafından oluşturulmadığı için, yönetim kurulunun yetki alanında kalan konuların, kuruluştaki esas sözleşme ile sınırsız bir şekilde düzenlenebileceğinden söz edebilir miyiz? Çalışmada söz konusu soruları değerlendirerek bir cevap bulmaya çalışacağız.
La idea de infinito: un desfundar lo total y fundar lo ético
Authors: Leiva Rubio Gabriel
Published: February 2024

Este ensayo practica una hermenéutica a Totalidad e infinito a partir de cinco epígrafes, abocados todos a explorar los múltiples sentidos de la propuesta levinasiana en torno al fundamento trascendental de lo ético. El primer apartado busca analizar la relación entre lo que Lévinas designa como la faz del ser y el concepto de totalidad; en el epígrafe siguiente se explicita la diferencia existente, en el interior de la comprensión temporal de lo total, entre lo histórico y lo escatológico; en el tercer epígrafe se analizan los móviles que llevan a Lévinas a sustituir lo metafísico por lo ético, revelando a este segundo saber como filosofía primera; y, finalmente, el cuarto y el quinto epígrafe quedan dedicados a entender dos conceptos que, entrelazados, condensan la matriz conceptual desde donde Lévinas acentúa la originalidad de su propuesta: el rostro del Otro y la idea de infinito.

Abstract

This research aims to delve into the understanding of acid-base concepts among students at SMA Negeri 1 Muara Batang Gadis from a macro to micro perspective. The research method used is qualitative study with a descriptive approach. Data were collected through observation, interviews, and analysis of documents related to the curriculum and chemistry learning materials. The results show that students' understanding of acid-base concepts is still limited at the macro level, with minimal understanding at the micro level. This indicates the need for a more holistic and integrated approach to learning, incorporating macro, micro, and symbolic theory in the teaching of acid-base concepts. Recommendations for further development include the use of integrated learning approaches that incorporate various methods, including laboratory experiments, simulations, and technology-based learning, to enhance students' understanding of concepts from a macro to micro perspective.

Higher Education Institutions Resilience During Covid‑19 Post-Pandemic: A Quantitative Approach
Authors: Abdullah Mokhtar , Omar Muhammad , Husin Nor Azilah , Bahardin Tun Mohd Izlizam
Published: February 2024

The pandemic of COVID-19 has had a significant impact on higher education institutions (HEI). The question is whether HEI have been able to adapt to the pandemic's new normal. There is a need for quantifying the impact of Covid-19 pandemic on HEI in a formal manner. This paper aims to presents a structural quantitative approach to operationalizing a proposed conceptual framework that addresses the resilience of HEI in response to the Covid-19 pandemic. So far, there has been little quantitatively based empirical research on HEI resilience. Even though several authors proposed formidable frameworks for conceptualizing organizational resilience, none of these studies presented quantitative evidence of the COVID-19 pandemic of HEI resilience. The current study aims to quantify the HEI resilience framework by measuring the inter-relationships between the components of the framework using Structural Equation Modeling with Partial Least Squares (SEM-PLS) method. The data from 121 public and private universities in Malaysia were collected and used as a basis for determining the significant relationships in the HEI resilience framework. The empirical findings demonstrated that the (higher order) three stages of HEI resilience, namely anticipation, coping, and adaptation, which were precedingly linked to four HEI capability (lower-order) constructs, namely knowledge-based, resources availability, social resources, and power-based, positively influence HEI Resilience. In the meantime, the knowledge-based and power-based capabilities of the HEI appeared to have significant indirect effects on their resilience via their adaptation stage. Recommendations for practice and research were also discussed.

The objectives of the research involve developing the procedure for fatigue life prediction using the S-N curve for the thermowell material and investigating the effects of fluid velocity, fluid density and cyclic loading on the thermowell structure using the engineering drawing tool, AutoCAD 2022, and simulation software, ANSYS Workbench 21.1. By comparing the results for the proposed fatigue life estimation to Diwakar’s study on fatigue life estimation of thermowells in supercritical operation, the percent error obtained was 0.11%, which indicates that the proposed method is an accurate and reliable tool to perform fatigue analysis. Afterward, the parametric study of the thermowell model was conducted to investigate the effects of fluid velocity, fluid density and geometric dimensions on the fatigue life of a thermowell. There were six load cases investigated for two thermowells, which were designed based on the minimum and maximum dimensional limit of the thermowell performance test code PTC 10.3 TW-2016. The parametric study results showed that the minimum thermowell performed better for all the load cases, which obtained a maximum number of cycles to failure of 8898 cycles for a maximum stress value of 869 MPa. Furthermore, the higher the fluid velocity and density, the higher the likelihood and occurrences of resonance, the lower the number of cycles to failure. Similarly, the higher the natural frequency of the thermowell, the lower the likelihood and occurrences of resonance; hence, the higher the number of cycles to failure. It was observed that the point where the stress value is highest, or the stress concentration zone, is the area between the flange and thermowell neck, which was consistent with the thermowell performance standard codes of practice, PTC 19.3 TW-2016.

HEAT TRANSFER ENHANCEMENT IN STIRLING ENGINE USING FINS WITH DIFFERENT CONFIGURATIONS AND GEOMETRIES
Authors: Ramahi Ahmad , Hamdan Hasan , Sham Dol Sharul
Published: February 2024

The temperature difference across a Stirling engine cylinder is one of the main factors contributing to the power output and efficiency. Stirling engine is a heat engine that operates through expansion and compression cycles through different fluid temperatures. In addition, the engine was noted to have three different configurations, which include the alpha, beta, and gamma types, which are discussed in work. This study aims to investigate the effect of adding various fin geometries on different engine cylinder locations to simulate and visualize heat transfer enhancement across the cylinder. The various configurations were simulated through the ANSYS Fluent commercially available CFD model, which was used to simulate the temperature difference on the hot and cold ends of the tested fins. A validation model of mesh element sizing has also been implemented to determine the accuracy of the achieved numbers. Moreover, Fusion360 has been used to 3D design different geometries, including annular, conical and rectangular fins.Furthermore, lastly, validation of the obtained simulated results will be conducted to monitor the accuracy of the simulation through two different methods. An effectiveness of 8.17 has been obtained through the simulation for annular fins; in addition, it has been determined that annular fins achieve the best temperature distribution among the selection of geometries and configurations simulated which was recorded as 223°C for the hot end and 40°C for the cold end.Keywords: CFD, simulation, fins effectiveness, fins efficiency, stirling engine, heat transfer

Published: February 2024

Carbon dioxide (CO2) is the most prominent greenhouse gas (GHG) present in the atmosphere, making it the most accountable for global warming. CO2 capture is capable of greatly reducing carbon emissions. The current method of CO2 capture by amine-based solvent has drawbacks, such as high demand for energy and intense corrosion, making it a less reliable method. More attention is given to ionic liquids (ILs) for their negligible vapour pressure, low melting point, and high chemical and thermal stability advantage. This study uses data analytics techniques to develop a predictive model for screening ILs for CO2 capture, moving away from the experimental approach, which is burdensome, costly, and less environmental-friendly. Data on the properties and parameters of ILs are collected from COSMO-RS software. CO2 solubility is the function of collected data and developed into 15 models of three different methods: Support Vector Machine (SVM), Neural Networks (NN), and Gaussian Process Regression (GPR). The use of data analytics in this field is new and can provide valuable insight towards CO2 solubility in ILs. The dataset is distributed randomly at 80/20% for training and testing. Each model is evaluated using R-squared and root mean square error (RMSE). The rational Quadratic GPR model shows the lowest RMSE of 0.0002 for training and testing, with R-squared the closest to 1. Rational Quadratic GPR is the best model to be used for screening IL for CO2 capture.
