Published: March 2024

Rapid industrialization and growth in population have resulted in a rapid increase in energy demand. Pollutant emissions from diesel engines have caused major impacts in disturbing the ecological system. The Malaysian government implemented the B10 biodiesel program for the transportation sector and B7 for the industrial sector in 2019 to drive the demand for palm oil and increase the sustainability of energy resources. For future implementation, the government is looking toward for higher percentage of blended biodiesel, such as B30 and above. This paper presented the effect of engine overhaul on the performance and emissions of a vehicle fuelled with blended biodiesel (B10, B20 & B30) by comparing before and after the engine overhaul. By using a vehicle Toyota Hilux 2.5L, the vehicle was attached to a chassis dynamometer for determining its performance such as brake power and brake specific fuel consumption (BSFC) at 45% and 90% of Acceleration Pedal Position (APP), respectively. The exhaust gas emissions were measured using a 5-channel analyser for determining the carbon dioxide (CO2), carbon monoxide (CO) and nitrogen oxide (NOx). The experiment was conducted in a steady-state condition with a constant speed of 30, 60, 90, and 110 km/h simulating rural, urban, and motorway speeds. The performance results revealed that blended biodiesel B10, B20 and B30, produced higher brake power, and lower brake-specific fuel consumption after engine overhaul. Emissions results showed that CO was increased at 45% APP but decreased at a higher 90% APP, and in most cases, NOx and CO2 emissions were decreased with an increase in speed for both APP.
Influence of Cavity on Base Pressure Manipulation in Suddenly Expanded Flow from Converging Diverging Nozzle for Area Ratio 5.29
Authors: Ridwan  , Sher Afghan Khan  , Jaffar Syed Mohamed Ali  , Mohd. Azan Mohammed Sapardi
Published: March 2024

This study delves into the intricate interplay of cavity placement, Nozzle Pressure Ratio (NPR), and Mach numbers, examining their collective influence on manipulating base pressure within a duct. Employing numerical simulations, the research explores the cavity's effectiveness in altering base pressure dynamics in the duct's base area. The investigation comprehensively studies various factors, including length-to-diameter ratio, nozzle pressure ratio, Mach number, and cavity location. The simulations are conducted for a singular cavity at multiple positions concerning the duct's diameter, maintaining a fixed cavity width-to-height ratio of 1. The NPR ranges from 2 to 8, and the Mach numbers under scrutiny span from 1.2 to 1.8. The study meticulously analyses variations in base pressure and alterations in the pressure field resulting from these variables. Notably, the findings demonstrate the cavity's adeptness in controlling base pressure, particularly at NPR values of 4 and 6 for Mach numbers 1.2 and 1.4. In contrast, ineffectiveness is observed at NPR 2 and 8 due to specific flow reattachment points. However, the cavity effectively influences base pressure at NPR values of 4, 6, and 8 for Mach numbers 1.6 and 1.8. These discernments offer invaluable insights for the optimization of duct designs in diverse engineering applications.

Authors: Mahadev Madivalappa Channakote  , Dilipkumar Vilasrao Kalse  , Asha Shivappa Kotnurkar  , Shekar Marudappa
Published: March 2024

MRI method is used in magnetic resonance imaging (MRI) to diagnose brain disorders by detecting the changing conditions within the brain. Peristaltic waves created on the flexible walls of the brain cause particles to move, and understanding this fluid flow can benefit the treatment of malignant tissues. In light of this, the electro-osmotic impact on the peristaltic flow of a fractional second grade fluid (ionic solution) in a microchannel with a heat and mass transfer is investigated. The governing equations of the modulated problem can be solved analytically by assuming a low Reynolds number (Re → 0) and a long wavelength (δ << 1). An analysis of the Poisson-Boltzmann equation is considered to examine the electro-kinetic mechanism. Using the Mathematica program, we solved a set of dimensionless equations and displayed the generated graphs. We analyzed relevant factors for their impacts on temperature, velocity, and pressure gradient. Biomedical engineers may find inspiration to create bio-microfluidic devices that aid in the movement of physiological fluids based on the model and its related findings.
PERENCANAA PRODUKSI PAVING BLOCK DENGAN MENGGUNAKAN MODEL PROGRAM DINAMIS (DYNAMIC PROGRAMMING) DI CV. SHOHAT GORONTALO.

Published: March 2024

This current research aimed to plan an optimal and scheduled production to minimize defects in production quantities, excess or shortage of production quantities with minimum costs. The method used was Dynamic Progamming to develop optimal scheduling, by forecasting average production using the Autoregressive Integrated Moving Average (ARIMA) model. The ARIMA was employed to forecast the average amount of production data of CV Shohat Gorontalo which were the data for the last 24 weeks or during 6 months. The result obtained was that the minimum cost was always obtained at the inventory figure I = 0, because having less inventory or even no inventory would reduce the total cost due to the small holding costs when compared to production costs. The cost incurred for the production schedule during the July- December of 2023 period was IDR 9,161,954,550. In addition, the data were the optimal result in minimizing production costs using the Dynamic Programming method. Abstract written in English. Abstracts are written in a sequence that contains the purpose of research, the methods used in research, research results, conclusions, suggestions, and research implications.

Investigation of the effect of nanoparticle shape on fluid flow and heat transfer performance of Al2O3-EG-H2O nanofluids: cases of a fixed Reynolds number and a fixed velocity at inlet
Authors: Boukerma Karima , Kadja Mahfoud
Published: March 2024

This study considers the shape effect of Al2O3 nanoparticles (platelets, blades,cylindrical and bricks) dispersed in an ethylene glycol-water base fluid (50-50%) on heat transfer and fluid flow. We have considered two different entry conditions: a constant Reynolds number (Re = 250) and a constant inlet velocity (Win=0.2 m/s).The physical model was developed using Gambit CFD for mesh and FLUENT for fluid flow modeling. The three-dimensional continuity, Navier–Stokes and energy equations are solved by using the finite volume method. We found that for Re = 250, the nanofluids with nanoparticles of platelet shape have the highest velocity, heat transfer coefficient, Nusselt number, pressure drop, and performance factor followed by nanofluids containing cylindrical nanoparticles.For a constant velocity at the inlet, nanofluids with nanoparticles of cylindrical shape have the highest heat transfer coefficient and the lowest Nusselt number while nanofluids with nanoparticles of platelet shape have the lowest heat transfer coefficient and the highest Nusselt number.
Bridging the Gap between Luminous Red Novae and Common Envelope Evolution: The Role of Recombination Energy and Radiation Force
Authors: Chen 陈 Zhuo 卓 , Ivanova Natalia
Published: March 2024

Luminous red novae and their connection to common envelope evolution (CEE) remain elusive in astrophysics. Here, we present a radiation hydrodynamic model capable of simulating the light curves of material ejected during a CEE. For the first time, the radiation hydrodynamic model incorporates complete recombination physics for hydrogen and helium. The radiation hydrodynamic equations are solved with Guangqi. With time-independent ejecta simulations, we show that the peaks in the light curves are attributed to radiation-dominated ejecta, while the extended plateaus are produced by matter-dominated ejecta. To showcase our model’s capability, we fit the light curve of AT 2019zhd. The central mass object of 6 M
⊙ is assumed based on observations and scaling relations. Our model demonstrates that the ejecta mass of AT 2019zhd falls within the range of 0.04–0.1 M
⊙. Additionally, we demonstrate that recombination energy and radiation force acceleration significantly impact the light curves, whereas dust formation has a limited effect during the peak and plateau phases.

Authors: Emsenhuber Alexandre , Asphaug Erik , Cambioni Saverio , Gabriel Travis S. J. , Schwartz Stephen R. , Melikyan Robert E. , Denton C. Adeene
Published: March 2024

In the late stage of terrestrial planet formation, planets are predicted to undergo pairwise collisions known as giant impacts. Here, we present a high-resolution database of giant impacts for differentiated colliding bodies of iron–silicate composition, with target masses ranging from 1 × 10−4
M
⊕ up to super-Earths (5 M
⊕). We vary the impactor-to-target mass ratio, core–mantle (iron–silicate) fraction, impact velocity, and impact angle. Strength in the form of friction is included in all simulations. We find that, due to strength, the collisions with bodies smaller than about 2 ×10−3
M
⊕ can result in irregular shapes, compound-core structures, and captured binaries. We observe that the characteristic escaping velocity of smaller remnants (debris) is approximately half of the impact velocity, significantly faster than currently assumed in N-body simulations of planet formation. Incorporating these results in N-body planet formation studies would provide more realistic debris–debris and debris–planet interactions.
La réforme des corps monastiques : Saint-Germain d’Auxerre aux ix e et xi e siècles
Authors: Greene Thomas A. E.
Published: March 2024

Les chercheurs envisagent souvent la réforme comme un processus imposé par le haut, se concentrant sur la mise en application rigoureuse d’une règle et sur les individus qui ont mené à bien des missions de réforme. Je souhaite ici inverser la perspective pour regarder la réforme à partir du bas et du point de vue des moines dont la vie et l’expérience de vie constituaient la cible des réformateurs. Je me pencherai d’abord sur le commentaire de la messe de Remi d’Auxerre († ca 908), ainsi que sur les homélies écrites par Haymon et Heiric, ses prédécesseurs à Saint-Germain, avant d’examiner la production textuelle de Saint-Germain relative au xi e  siècle. L’examen de ces textes permet d’affirmer que la compréhension de l’expérience vécue des corps monastiques est indispensable à la compréhension du monachisme au sens large. La réforme monastique a en effet bouleversé la vie quotidienne des moines, leurs perceptions sensorielles et leurs expériences émotionnelles. La réforme a affecté leur corps, et c’est précisément de ces corps qu’il faut partir pour comprendre la réforme.
Preuves ostéologiques de pratiques alimentaires anciennes : une nouvelle piste pour l’étude des réformes carolingiennes
Authors: Burridge Claire
Published: March 2024

Certaines sources textuelles suggèrent que la législation réformatrice promulguée par la cour carolingienne a eu un impact significatif sur les communautés ecclésiastiques. L’harmonisation des règles monastiques et canoniales au concile d’Aix-la-Chapelle en est un exemple. Dans le présent article, je présente quatre techniques archéologiques susceptibles d’être utilisées pour examiner les pratiques alimentaires anciennes et éclairer ainsi un aspect important de la vie des membres de ces communautés. Ces méthodes peuvent également nous renseigner sur les potentiels changements et variations entre communautés pendant cette période critique de l’histoire du monachisme. L’abbaye de Lorsch constitue à ce titre un site idéal à partir duquel intégrer à l’avenir ces techniques à la recherche.
Mettre en place un groupe d’APP. De l’analyse de la demande à la négociation du dispositif
Authors: Nicot Anne-Laure
Published: March 2024

L’analyse des pratiques professionnelles est un dispositif de plus en plus sollicité dans le secteur social. Demande qui peut être faite aussi bien à l’initiative de la direction de structures que par les travailleurs sociaux, chacun pouvant définir des objectifs différents. De plus, cette hausse amène à une mise en concurrence des intervenants posant la question du recrutement et de la marge de manœuvre dans l’aménagement du dispositif par rapport à la commande initiale. Trois enjeux derrière la mise en place de l’analyse des pratiques professionnelles. Celui de la formulation de la demande pour définir les attentes. Celui de co-construction et de négociation pour aboutir aux modalités organisationnelles. Enfin, la dimension éthique dans la posture de l’intervenant. L’intervenant ne doit pas définir seul les objectifs. Ces derniers devraient être le résultat d’une analyse de la demande pour déterminer les besoins et le recrutement de l’intervenant.
25 ans après l’exhortation apostolique « Nouvelle espérance pour le Liban ». L’actualité de l’Église au Liban
Authors: Noujaim Guy Paul
Published: March 2024

Après l’exhortation « Nouvelle Espérance pour le Liban » du pape Jean-Paul II, le texte souligne l’importance de l’accompagnement et du concept de « Ensemble » dans l’Église et la société libanaise, prônant la coopération et la construction commune dans un esprit ecclésial. Il examine la situation actuelle du Liban, son rôle, l’état de l’Église et ses liens sociaux, mettant en évidence les défis socio-politiques du pays et promouvant l’unité nationale en dépit des difficultés. Il met en relief le rôle unique du Liban en tant que symbole de liberté et de pluralisme régional. Concernant l’Église, il aborde sa structure, son engagement social et ses défis internes, critiquant l’approche individualiste de certaines institutions ecclésiastiques et encourageant une collaboration plus large pour le bien-être collectif.
Le concept de conversion
Authors: Smadja Claude
Published: March 2024

La conversion est une notion créée par Freud dans les années 1890 pour spécifier le mécanisme de la formation des symptômes hystériques et leur impact somatique. Elle est liée au destin du quantum d’affect après le refoulement des représentations jugées inconciliables pour le moi. En raison de sa double nature, psychique et somatique, elle se situe au cœur d’une problématique psychosomatique. C’est sur les deux notions de refoulement et de complaisance somatique que repose, pour Freud, le modèle théorique des symptômes de conversion. Georges Parcheminey récuse la pertinence de ce modèle et propose un modèle génétique renvoyant à un stade supposé précoce d’indifférenciation somato-psychique. Il substitue ainsi à la conception d’une dualité de fonctionnement celle d’une identité entre le psychique et le somatique. Pour Pierre Marty, le processus de conversion est interprété comme un mouvement de régression aboutissant à des fixations somatiques pleines d’un potentiel libidinal apte à relancer le mouvement d’organisation psychique. Les travaux contemporains des psychosomaticiens ont prolongé les premières analyses freudiennes des névroses et ont enrichi la compréhension des symptômes de conversion en montrant toute leur complexité.
Le cas Dora revisité
Authors: Schaeffer Jacqueline
Published: March 2024

L’intérêt de revisiter Dora aujourd’hui, c’est d’interroger ce qui, des symptômes et de la structure, revient à l’hystérie ou aux affections psychosomatiques. C’est une question qui reste toujours d’actualité, car la personnalité hystérique ainsi que les symptômes qu’elle présente, sa labilité, la multiplication de ses identifications utilisent toutes les couleurs de la psychopathologie et des constructions défensives. Des prolongements actuels interrogent : les jeux hystériques de la séduction et de la jalousie, la haine de la scène primitive, le conflit entre une sexualité infantile hyper-érotisée, autoérotique et une sexualité génitale contre-investie, les identifications, le masochisme érogène primaire, la complaisance somatique, l’homosexualité et la pseudo-bisexualité. L’analyse du transfert et du contre-transfert est un levier essentiel de la cure de l’hystérique. Ce que Freud n’a pu sentir, ni prévenir, ni interpréter aboutira à l’agir par la rupture du traitement de Dora.
L’hystérie et les affres du désir
Authors: De Vincenzo Mario
Published: March 2024

L’article tente de problématiser la question de la demande de l’hystérique qui confronte le psychanalyste aux écueils d’un désir de non-satisfaction. À partir du récit d’une cure, l’auteur met en lumière les paradoxes de cette demande de l’hystérique qui se débat constamment entre un donner à voir à travers ses symptômes et un invisible qui se dérobe. À partir de l’étude des enjeux transféro-contre-transférentiels et de la phénoménologie des identifications hystériques, ce travail tente de comprendre l’accrochage de l’hystérique à la non-satisfaction comme nécessité de préserver une tension suscitant dans et par l’autre des effets de reconnaissance pouvant répondre à la nécessité de représent. L’inadéquation consubstantielle entre l’offre et la demande dans les cures des hystériques réactualiserait ainsi la quête impossible d’une relation originaire porteuse de la plénitude et de la reconnaissance que l’hystérique ne cesse de chercher dans le regard de l’autre.
Le modèle de l’hystérie traumatique : un paradigme à l’adolescence ?
Authors: François-Poncet Claire-Marine
Published: March 2024

Comment le modèle de l’hystérie traumatique, à l’origine de la psychanalyse, s’applique-t‑il à la clinique contemporaine de l’adolescence ? L’auteur interrogera la valeur paradigmatique de ce modèle à l’adolescence en remettant au travail la théorie de la séduction dans des histoires cliniques de jeunes filles désignées hystériques par Freud. Comme ces jeunes filles, les adolescentes d’aujourd’hui affichent dans leur corps l’excès d’excitation subi dans l’enfance. Victimes des mouvements passionnels inconscients des adultes, elles tentent de s’approprier l’histoire des générations précédentes en mettant des mots sur les préjudices infantiles inconscients. L’auteur fera l’hypothèse que la résolution du complexe de castration chez les filles suppose un travail d’intégration de la sexualité infantile, traumatique, au service de la continuité de la vie psychique. Ce travail continue d’être symbolisé dans la culture par l’accès au maternel dans sa transmission des règles qui définissent l’amour.
Mise en perspective de la pensée de James et Eileen Brockman Goggin à partir de leur livre : Mort d’une science juive, la psychanalyse durant le III e Reich
Authors: Valon Philippe
Published: March 2024

Il s’agit d’un livre portant sur la psychanalyse en Allemagne entre 1933 et 1945 et après, publié en 2001, non traduit en français. Ce n’est que dans les années 1980 qu’a débuté l’étude de ce qui s’est passé pendant ces années du nazisme : « Mort d’une science juive » est le titre du livre, qui est postérieur au livre de G. Cocks et aux travaux de R. Lockot. Pour les auteurs, la psychanalyse est morte pendant cette période. Incompatibilité entre psychanalyse et doctrine politique. Dès 1934-1935, les analystes juifs commencent à émigrer. Eitingon quitte l’Allemagne dès novembre 1933. En 1935, les membres juifs de la société psychanalytique sont contraints de démissionner. Boehm et Müller-Braunschweig prennent la direction. La psychanalyse se nazifie. Voir les articles de Müller-Braunschweig et aussi ceux de Jung, antisémites et racistes. L’institut Göring, la psychanalyse et la science sont des entreprises juives qui doivent être éradiquées. Jones participe au sauvetage des psychanalystes juifs, ce qui doit être différencié du sauvetage de la psychanalyse. Compromis, collaboration et résistance des psychanalystes allemands. Certains le paieront de leur vie. Plank résiste, au contraire de Müller-Braunschweig, Boehm et autres. Après la guerre, Scheunert, ancien membre du parti nazi, participe à la fondation de la DPV avec Müller-Braunschweig. La DPG exclue de l’API quand la DPV est admise presque immédiatement. Enfin se pose la question de l’éthique de la psychanalyse.
Berlin 1933 : l’uniformisation cachée de la psychanalyse
Authors: A. Dittrich Karin , Schmidt auf Altenstadt Wolfgang
Published: March 2024

Après la prise de pouvoir par Hitler en 1933, les membres non juifs de la Deutsche Psychoanalytische Gesellschaft (DPG), Felix Boehm et Carl Müller-Braunschweig ont réussi rapidement à prévenir la menace immédiate de dissolution de l’association. L’objet de cet article est d’examiner comment ce discret et surprenant « salut » de la DPG en tant qu’organisation est devenu possible, par l’entremise d’un membre dirigeant de l’organisation nazie « Alliance de combat pour la culture allemande ». Il sera montré quel était le prix sur l’avenir que Boehm et Müller-Braunschweig étaient disposés à payer, sans en faire un sujet de discussion avec les commissions de la DPG et sans en parler avec les représentants de l’API comme Jones ou Ophuizen, ou avec Freud lui-même : l’exclusion complète à moyen terme des membres juifs de l’association et des racines juives de la psychanalyse. Certes, le retrait de tous les membres juifs de la DPG n’a pas eu lieu avant 1935 et la DPG a survécu jusqu’en 1938, mais le réglage occulte des points déterminants du « développement » futur de la psychanalyse en Allemagne a eu lieu dès août 1933. Après la guerre, Boehm est devenu une figure dirigeante de la DPG reconstituée, alors que Müller-Braunschweig a fondé la nouvelle Deutsche Psychoanalytische Vereinigung (DPV).
Le temps du Préconscient
Authors: Baruch Clarisse
Published: March 2024

Les vécus d’identité, d’écoulement du temps et la mémoire entretiennent des rapports métapsychologiques étroits. Freud les a étudiés dans différents textes, amenant en particulier l’atemporalité de l’inconscient et la non-durabilité de la mémoire dans la conscience, sans les situer explicitement dans le sas intermédiaire, le préconscient. De courtes vignettes cliniques montrent comment s’organise si différemment le vécu temporel en fonction de l’organisation psychique : temps gelé de la psychose, temps accéléré de la manie, témoignant d’un préconscient dysfonctionnel, temps long de la symbolisation intégrant la durée de l’absence et le temps de la latence. Un préconscient fonctionnel rend possibles les trajets de l’inconscient au conscient, dans les deux sens, amenant porosités et souplesses à l’ensemble du psychisme. Le monde fantasmatique s’y développe également, en s’appuyant sur l’expérience de la discontinuité. Mais cette discontinuité n’est tolérable que si un mécanisme de liage temporel relie les événements psychiques au cours du temps, comme les notes discontinues se regroupent en musique. C’est alors que l’écoulement du temps, les images mémorielles et le sentiment d’existence peuvent dans un même mouvement psychique permettre un vécu de continuité.

Authors: Ermawati Nanik , Dianawati Wiwiek
Published: March 2024

Purpose: The primary purpose of this study is to see the impact of the presence of a woman board of commissioners (WBoC) on firm performance (FP). In addition, this study looked at the effect of moderation of family ownership (FO) on the influence of WBoC on FP.Design/methodology/approach: This study used secondary data with a sample of all companies listed on the Indonesia Stock Exchange from 2017 to 2021. The study used a total of 788 observations. The data were analyzed using moderate regression analysis with unbalanced panel data.Findings: The results revealed that WBoC did not affect TQ and ROA. Empirical research shows that FO strengthens WBoC in increasing ROA and TQ.Research limitations/implications: In Indonesia, the portion of the representation of each company's woman board of commissioners is only one member on average at 78%. As many as 22% of companies with a board of commissioners are more or equal to 2 members.Practical implications: This study also serves as a guide for shareholders in selecting competent woman boards of commissioners for an effective supervisory system that drives the company's success.Originality/value: This study analyzes the impact of share ownership dominated by family companies on the relationship between the existence of a woman board of commissioners and firm performance. Therefore, this research is significant to understand the role of FO in helping women build leadership, gain recognition, and be empowered to improve firm performance.

Authors: Syifaul Fuada  , Mariella Särestöniemi  , Marcos Katz
Published: March 2024

In the present era of advanced medical technology, there has been a significant increase in the utilization of wireless-based implantable medical devices (IMDs) in various biomedical applications, including health diagnosis, monitoring, recording, treatment, and other clinical concerns. It is essential to closely examine the research trends in wireless IMD topics to understand their growth trajectory. This can be achieved through the utilization of bibliometric reviews. While there are numerous experimental studies and survey papers on the topic, there is a dearth of review papers that utilize a bibliometric approach. Therefore, this study aims to conduct a bibliometric analysis to identify emerging research trends in wireless IMDs for biomedical applications for the first time. An analysis was conducted on 1,650 articles retrieved from the Scopus database from its inception until September 2023. The study used tools such as VOS Viewer to measure performance and science map parameters, and Tableau Cloud to visually enhance the analysis process. This research endeavor allowed us to analyze historical trends, influential papers, top journals, institutions, countries, and authors within this field. The top three influential journals in this field are IEEE Transactions on Biomedical Circuits and Systems, IEEE Transactions on Antenna and Propagation, and IEEE access. The National University of Singapore is the most productive institution in terms of overall publications. The United States, China, and India make significant contributions to overall publications. Finally, we also examined the most significant keywords and current research areas within this field.
Evaluation of an Indoor Location System Using Edge Computing and Machine Learning Algorithms
Authors: Yauri Ricardo , Espino Rafael , Castro Antero
Published: March 2024

The paper aims to evaluate precise location techniques with indoor devices using edge computing technologies, which are important for services such as smart homes and health. Despite their growing importance, indoor locations lack precise and standard methods, especially in complex environments. Solving this is being attempted through technologies such as reconfigurable surfaces and deep learning models, with attention to overcoming the challenges of indoor placement. The main objective of the study is to design a low-cost indoor location system using the ESP32 module and RSSI signals, integrated with embedded machine learning algorithms. The system to be developed will allow determining the location of objects or people with a location device through SSID signals from access points. The main objective is to evaluate the performance of three machine learning algorithms—random forest (RF), decision tree (DT) and support vector machine (SVM)—in the detection of four different locations (bathroom, kitchen, bedroom, and living room), involving the definition of system characteristics, data acquisition, the development of classifiers, and their integration in the ESP32 module to transmit location data wirelessly through the MQTT protocol. As a result of the evaluation, the DT model stands out for its efficiency under limited resource conditions during real-time implementation, but it may face challenges related to overfitting and resources at the implementation stage.

Authors: Aliquot Julien , Hazza Muaffaq
Published: March 2024

Abstract – This article offers the editio princeps of two epigraphic documents recently discovered in the southern, Jordanian part of Ḥawrān at Umm al-Jimāl, south of Bostra, the capital of the Roman province of Arabia. The first inscription is a Greek dedication of an altar that a beneficiarius addressed to Zeus Keraunios under the Severi. The second is a Latin inscription dealing with the building of a tower in the fourth century ce under the authority of the dux Flavius Maximinus. The publication of both texts provides an opportunity to review the sources relating to presence of the Roman army at Umm al-Jimāl from the creation of Provincia Arabia (106 ce) to the reign of Justinian (527-565 ce). On a broader level, the aim is to contribute to the ongoing discussion of the relationships between soldiers, villagers, and nomads in the limes Arabicus.

Published: March 2024

This chapter discusses algorithmic energy conservation in multi-cell multiple-input multiple-output (MIMO) downstream transmission. The authors propose using adaptive particle swarm optimization (APSO) to reduce the optimization issue. By framing the issue as a limited optimization assignment, they present a solid framework that allocates transmission power levels to antennas to maximize energy efficiency and meet network customers' quality of service. To evaluate the technique, they simulated various network settings with different user distributions and channel conditions. The approach outperforms previous energy-saving methods without losing the whole network sum rate, increasing energy efficiency significantly. By using optimal antenna components and the best fitness value, the proposed APSO model guarantees better power allocation schemes in wireless environments than current approaches.

The parallel development AI and ML is a boon to humanity. It eases the safety and livelihood of people who need to be under constant observation. Artificial intelligence (AI) and machine learning (ML)-enabled healthcare systems aid in the observation of elderly people. Nowadays, elderly people are severely affected while they fall. Falling down might occur due to several reasons like high or low blood pressure, diabetes, Parkinsonism, heart attack, cardiac arrest, brain tumour, and many more. The working lifestyle of other family members leaves the elderly alone and demands observation. For observing such home alone elderly people, the family members depend on exclusive caretakers and healthcare monitoring systems (HMS). When caretakers take off, family members depend on HMS. Henceforth, we need an effective HMS comprising sensor networks, data acquisition and pre-processing, computer vision (CV) module, AI and ML module, decision making and alerting, and especially, user interface.

One type of technical rubber that is currently imported is a pneumatic fender, which mostly only uses synthetic rubber as raw material. Whereas natural rubber has superior mechanical properties that are better than synthetic rubber. This research will combine natural rubber (RSS) with EPDM synthetic rubber by varying the RSS/EPDM mass ratio. This study aims to determine the effect of the mass ratio of RSS/EPDM on the quality of the mechanical properties of pneumatic fender compounds. The rubber compound is made with a ratio of RSS/EPDM: 100/0, 90/10, 80/20, 70/30, and 0/100. The mechanical testing was carried out under normal and aging conditions. The test results showed that the mass ratio of RSS/EPDM rubber affected the mechanical properties of the resulting rubber compound. The rubber compound formula containing EPDM 10 to 30 phr is suitable for pneumatic fender applications due to better properties and resistance after aging, particularly compression set.
