Authors: Abdul Rahman Farhan Sabdin  , Che Haziqah Che Hussin  , Jumat Sulaiman  , Arif Mandangan
Published: May 2024

This paper obtains semi-analytical solutions for the nonlinear Schrodinger equations (NLSEs) using the multistep reduced differential transform method (MsRDTM). The implemented method yields an analytical approximate solution over a longer time frame, in which the method applied is treated as an algorithm in a sequence of small sub-division of intervals of identical length compared to the traditional reduced differential transform method (RDTM). Excluding the need of perturbation, linearization, or discretization, this method offers the benefit and reliability of the multistep algorithm. The outcomes show that the MsRDTM generated highly accurate solutions of NLSEs than the RDTM. In addition, the results show that the suggested method is straightforward to use, saves a significant amount of computing work when solving NLSEs, and has potential for broad application in other complex partial differential equations (PDEs) in the fields of engineering and science. The accuracy of the method is shown through the tables and graphical illustrations provided.
Double Resonance Characteristic of Photonic Crystal Structure with Defect Metal Layer
Authors: Teguh Puja Negara  , Sudradjat Supian  , Subiyanto  , Mohd Kamarulzaki Mustafa
Published: May 2024

The optical response of the photonic crystal structure has been analyzed using the Finite Difference Frequency Domain (FDFD) method. Simulation using this method aims to analyze the characteristics of light transmission when interacting with related structure. The results of the study of photonic crystal structures with two defects show that there are two transmittance bands called double resonances at two specific wavelengths. Changes in the resonance peak with respect to the variations of refractive index in the second defect layer resulted in a linear change with significant sensitivity. For photonic crystals with two defects, the first defect is a metal layer and the second defect is material sensing, which produces double resonance with a sensitivity of 7,825 and 3,2675, while for photonic crystals with the first defect, a dielectric layer, and the second defect is material sensing, produces single resonance with a sensitivity of 2,022. The choice of the first defect is that the metal layer is quite important, in addition to producing greater sensitivity, it also produces a field enhancement between the dielectric and the metal layer which is called surface plasmon resonance (SPR). The sensitivity value can also be set by determining the thickness of the second defect layer. These results can be used as a standard for fabrication and developed for sensor applications.

Electronic technology makes work more manageable, and various electronic gadgets have been invented to assist humans. One of the most time-consuming activities is household chores, such as laundry. Daily laundry tasks are easier to manage with the help of washing and drying machines. However, the folding task is still done by hand and is not automated. A towel is one of the main clothes in daily life. Commonly, people use bare hands to fold the towel. However, this task consumes much time and energy; consequently, boredom, tiredness, and fatigue occur. The existing device to fold towels usually has a large physical compartment and is mainly used for industrial purposes, such as at hotels or laundry shops. The towel-folding machine is in increasing demand in our daily lives. Therefore, this project was developed and designed to eliminate the tedious folding of towels. The main aim is to design and develop an effective mechanism for folding rectangular towels using electronic components. The other objective is to compare the timing of folding rectangular towels using a simple device and by hand. As a result, the prototype represented a semi-automation system incorporating mechanical and electronic designs. The prototype assembly has a folding board made from polypropylene plastic. The amount of time to fold one towel using a semi-automatic folding board remains the same throughout the process, while the amount of time required to fold towels by hand increases. In conclusion, a prototype was designed and developed successfully with various electronic components: HC-SR04 ultrasonic sensor, MG996R servomotor and Arduino. Besides, by comparing the timing of folding rectangular towels using a simple device and by hand, 94 seconds was reduced when folding 50 sheets with the aid of the device, compared to by hand. In other words, the effectiveness of the device is 20%.

Published: May 2024

Smoothing is a method of data analysis that aims to provide well-defined patterns or signals by removing noise or unstructured patterns from data sets. To obtain clean and smooth data, Hanning is applied as one of the important components in smoothing. However, Hanning is not resistant to outliers. Therefore, this study aims to determine the best type of Hanning that is able to obtain the greatest performance of 4253HT smoother in signal recovery. Functions of Linear, Complex Sinusoidal, Custom Pulse Train, and Sawtooth signals corrupted with five levels of contaminated normal noise were used as signals in the smoothing process. All signals were applied to assess three different Hanning types, which were Tukey, Husain and Shitan. Besides, a Root Mean Square Error (RMSE) was used as an evaluator to determine and assess the performance of 4253HT smoother when utilizing an alternative Hanning. Based on the overall performance of 4253HT smoother, Husain Hanning presented the best outcome and worked most efficiently at all levels of noise except at the lowest noise (10%), which Tukey Hanning executed better. The findings of this study could benefit other researchers to decide the best Hanning to be used before performing forecasting and further analysis to improve the accuracy of predicting.
Monitoring the Dynamics of Sedimentary Load Variations Along Coastal Regions Using UAVs After Monsoon and High Tide Events at Pantai Punggur and Pantai Perpat, Batu Pahat, Johor
Authors: Muhamad Syamil Sabri
Published: May 2024

This research investigates the changes in sedimentary load along the Pantai Punggur to Pantai Perpat coastline in Batu Pahat, Johor, particularly during the northeast monsoon period from October 2022 to February 2023. The study aims to produce a mapping diagram of the shoreline profile and volume changes across various locations and their association with monsoon changes. The research utilised aerial images captured by UAVs, which were analysed using Pix4D and Global Mapper software. Data was collected for six months from September 2022 to February 2023, with the observation period experiencing a high tide phenomenon on November 24, 2022, resulting in a significant change in the data for that month. Shoreline profile results did not establish a conclusive link between sediment load changes and erosion or accretion due to the lack of volumetric data. Consequently, an analysis of volume changes was conducted using the Global Mapper application. In conclusion, the northeast monsoon wind and high tide phenomena during November 2022 significantly impacted the shoreline profile and total volume of the Pantai Perpat and Pantai Punggur areas.

Published: May 2024

Numerical analysis of fins effect on propeller performance was conducted, specifically using the B4-70 and Ka4-70 propellers. The study investigated different types of fins, including bare fins and PBCF (Propeller Boss Cap Fins) using computational fluid dynamics (CFD) simulations. The explicit algebraic stress model (EASM) based on Reynolds-Averaged Navier-Stokes (RANS) equations and turbulence modeling was employed to determine the optimal results. The main objective of this research was to enhance energy efficiency in ships by examining various open propeller configurations. The CFD simulation results for open propellers B4-70 and Ka4-70, with the addition of boss cap fins, revealed interesting phenomena. When the open propellers B4-70 and Ka4-70 were equipped with PBCF, they would experience an increase in efficiency (η0). This was because the performance of the fins functioned optimally when the advance ratio (J) is high, as evident from the high velocity values. Thus, with higher velocity and lower pressure in the boss cap region at high J values, there was an elevation in thrust force due to the reduction of hub vortex. In the case of open propeller B4-70 with added PBCF, there was an increase in the efficiency value (η0) ranging from 3% to 5% when J varied from 0 to 0.7. Similarly, for propeller Ka4-70 with the addition of PBCF, there was an increase in the efficiency value (η0) ranging from 1% to 3% when J varied from 0 to 0.7. Notably, the use of an Energy-Saving Device (ESD) in the form of PBCF can increase the efficiency of ship propeller, as reported in this paper. Consequently, these findings affirmed the reliability of the overall calculations using the CFD approach.

Published: May 2024

Hybrid solar drying chamber is an application that is widely used today for agriculture products because it can promise the hygiene of the product. However, drying chambers nowadays still lack uniformity in drying products within a drying chamber, leading to food wastage and compromised product quality. This study aims to design an innovative hybrid solar drying chamber system and investigate the uniformity of temperature and velocity within the chamber using Computational Fluid Dynamics (CFD). The methodology involves validating the simulation results by comparing them with existing journal data, with a validation error of less than 5%. A new design is proposed after the validation process, considering factors such as tray arrangement and air inlet size. The results show that a tray arrangement with 0.20 m spacing between each tray provides better uniformity in temperature and air velocity distribution compared to other arrangements. Additionally, an inlet size of 0.05 m2 demonstrates the most suitable temperature distribution for drying purposes, falling within the ideal range of 318 K to 343 K. The study showed that the performance of the drying chamber under different operating conditions has consistent temperature distribution and is suitable for uniform drying. Overall, the proposed hybrid solar drying chamber system offers improved temperature control and uniformity for effective drying process.

Agency under German Occupation: Conservationist Policy-Making in The Netherlands, 1940–1945
Authors: MENNEN KRISTIAN
Published: May 2024

The paper provides a political history of nature conservation in the Netherlands during the Second World War, 1940–1945. Nature and nature conservation were not mere victims of Nazi German oppression or destruction; rather, conservationist organisations clearly had agency under difficult circumstances. The movement’s leaders were accustomed to using informal contacts, semi-formal arrangements and back channel deals with government authorities and agencies, and continued to exert influence on the new Department of Education, Science and Protection of Culture with considerable success after 1940. Although these consultation structures and the Department’s power to impose measures by decree could not always prevent severe damage, this story sheds new light on the history of the nature conservation movement as an historical actor in its own right under the conditions of war and occupation.

“Extended Emission” from Fallback Accretion onto Merger Remnants
Authors: Musolino Carlo , Duqué Raphaël , Rezzolla Luciano
Published: May 2024

Using a set of general-relativistic magnetohydrodynamics simulations that include proper neutrino transfer, we assess for the first time the role played by the fallback accretion onto the remnant from a binary neutron star merger over a timescale of hundreds of seconds. In particular, we find that, independently of the equation of state, the properties of the binary, and the fate of the remnant, the fallback material reaches a total mass of ≳10−3
M
⊙, i.e., about 50% of the unbound matter, and that the fallback accretion rate follows a power law in time with slope ∼t
−5/3. Interestingly, the timescale of the fallback and the corresponding accretion luminosity are in good agreement with the so-called “extended emission” observed in short gamma-ray bursts (GRBs). Using a simple electromagnetic emission model based on the self-consistent thermodynamical state of the fallback material heated by r-process nucleosynthesis, we show that this fallback material can shine in gamma and X-rays with luminosities ≳1048 erg s−1 for hundreds of seconds, thus making it a good and natural candidate to explain the extended emission in short GRBs. Additionally, our model for fallback emission reproduces well and rather naturally some of the phenomenological traits of extended emission, such as its softer spectra with respect to the prompt emission and the presence of exponential cutoffs in time. Our results clearly highlight that fallback flows onto merger remnants cannot be neglected, and the corresponding emission represents a very promising and largely unexplored avenue to explain the complex phenomenology of GRBs.
Revisiting the phylogeny and taxonomy of the genus Sidera (Hymenochaetales, Basidiomycota) with particular emphasis on S. vulgaris
Authors: Fryssouli Vassiliki , Polemis Elias , Typas Milton A. , Zervakis Georgios I.
Published: May 2024

The genus Sidera (Hymenochaetales, Basidiomycota) comprises white-rot, mono- or dimitic fungi with poroid or hydnoid hymenophore. It has a worldwide distribution albeit with fewer species present in the Southern Hemisphere. Although recent studies revealed the existence of several new Sidera species, there are still taxonomic inconsistencies and obscure phylogenetic relationships amongst certain taxa of the genus. In this work, a large number of Sidera collections were used to obtain an updated phylogeny, based on ITS and 28S rDNA sequences by including new material from Mediterranean Europe. The monophyly of the genus was strongly supported and all species with poroid hymenophore formed a highly-supported lineage with two major subclades. In total, 23 putative species were recognised. Amongst those, five are considered to possibly represent entities new to science, but further work is required since they are represented by single specimens or environmental sequences. Examined collections originally named S. lenis from southern Europe were grouped within S. vulgaris. Similarly, several collections under various names were hereby identified as S. vulgaris, including those of the recently described species S. tibetica. Furthermore, a critical discussion (based on morphoanatomical findings) is made on the key features that could be used to distinguish S. lenis from S. vulgaris.
Une crise du travail française
Authors: Méda Dominique
Published: May 2024

Alors que l’espace public est rempli de rumeurs stigmatisant la préférence française pour le loisir, pointant du doigt une « épidémie de flemme » et la perte du sens de l’effort, cet article s’intéresse à la dégradation des conditions de travail, particulièrement intense en France, qui continue malheureusement de faire l’objet d’un véritable déni.
Structuration des pratiques de gestion des ressources humaines dans les entreprises familiales : entre découragement et persévérance
Authors: Goter Françoise
Published: May 2024

Dans cet article, nous étudions l’évolution des pratiques RH d’une entreprise familiale de 120 personnes, dont les données (entretiens, indicateurs RH…) ont été collectées dans le cadre d’une recherche-intervention longitudinale de sept ans. Jusqu’à présent la littérature indique que les entreprises familiales favorisent les pratiques de GRH informelles, facteurs de confiance et de travail en équipe entre les membres de la famille et les non membres. De plus, peu de travaux font le rapprochement entre l’état des pratiques RH des entreprises familiales et leurs résultats socio-économiques. Or, notre étude montre que les pratiques informelles de GRH peuvent être une « zone de confort », génératrices de dysfonctionnements, de démotivation, d’absentéisme, de rotation du personnel et de perte de productivité au sein des entreprises familiales. À contrario, la professionnalisation des pratiques RH est source de cohésion entre les membres de la famille, de transparence auprès des équipes et d’amélioration des conditions de travail.
Contrats de travail et emploi dans un modèle ville-périphérie
Authors: Contensou François , Vranceanu Radu
Published: May 2024

Prenant en considération l’accroissement des coûts de transport subis par les travailleurs, cet article propose d’étudier la formation des contrats de travail conçus par un employeur s’adressant à deux populations de collaborateurs, populations qui diffèrent par la distance séparant leur domicile et le lieu de production. L’employeur cherche à en obtenir un volume d’heures prédéterminé. L’état de la législation du travail explique que des contrats distincts sont possibles mais soumis au libre choix des travailleurs, la discrimination explicite étant exclue. Le modèle précise l’effet des différences de coût et de durée du transport sur les rémunérations et les horaires choisis par l’employeur, et sur les effectifs demandés des deux catégories.

Characterizing edge-based doubly resolving sets within circulant networks $ C_n(1, 2) $
Authors: Nasir Ruby , Ahmad Muhammad , Zahid Zohaib , Bajri Sanaa A. , El-Wahed Khalifa Hamiden Abd
Published: May 2024

The focus of this article lies on the notion of the edge version of doubly resolving sets (EVDRSs) in circulant networks. EVDRSs refer to unique edge subsets that are necessary for identifying individual edges in a network and distinguishing them based on their edge distances to the elements of the EVDRS. The main objectives were to define the minimal size of EVDRSs for circulant networks $ C_n(1, 2) $ and to investigate their basic properties. The systematic research helped to achieve a new understanding of the existence, construction, and characterization of EVDRSs in circulant networks $ C_n(1, 2) $. It is established that the EVDRSs in the circulant network $ C_n(1, 2) $ are finite and are bounded by the order of the network. Among the numerous implications of these findings are those that refer to the design and optimization of distributed sensor networks, improving communication and network protocols, as well as tracking the spread of infectious diseases and epidemics over social networks. The application of the identified methodology helps improve the process of network optimization which contributes to the development of more effective and robust circulant-based structures.
The properties of generalized John domains in metric spaces
Authors: Liu Hongjun , Yan Fang , Xia Ling
Published: May 2024

In this paper, we studied the properties of generalized John domains in metric space. We prove that a domain $ D $ is a $ \varphi $-John domain if, and only if, $ D\backslash P $ is a $ \varphi' $-John domain, where $ P $ is a subset of $ D $ containing finitely many points of $ D $. Meanwhile, we also showed that the union of $ \varphi $-John domains is a $ \varphi'' $-John domain in metric space.
Hyperideal-based zero-divisor graph of the general hyperring $ \mathbb{Z}_{n} $
Authors: Hamidi Mohammad , Cristea Irina
Published: May 2024

The aim of this paper is to introduce and study the concept of a hyperideal-based zero-divisor graph associated with a general hyperring. This is a generalized version of the zero-divisor graph associated with a commutative ring. For any general hyperring $ R $ having a hyperideal $ I $, the $ I $-based zero-divisor graph $ \Gamma^{(I)}(R) $ associated with $ R $ is the simple graph whose vertices are the elements of $ R\setminus I $ having their hyperproduct in $ I $, and two distinct vertices are joined by an edge when their hyperproduct has a non-empty intersection with $ I $. In the first part of the paper, we concentrate on some general properties of this graph related to absorbing elements, while the second part is dedicated to the study of the $ I $-based zero-divisor graph associated to the general hyperring $ \mathbb{Z}_n $ of the integers modulo $ n $, when $ n = 2p^mq $, with $ p $ and $ q $ two different odd primes, and fixing the hyperideal $ I $.
Graphs with a given conditional diameter that maximize the Wiener index
Authors: An Junfeng , Tian Yingzhi
Published: May 2024

The Wiener index $ W(G) $ of a graph $ G $ is one of the most well-known topological indices, which is defined as the sum of distances between all pairs of vertices of $ G $. The diameter $ D(G) $ of $ G $ is the maximum distance between all pairs of vertices of $ G $, and the conditional diameter $ D(G; s) $ is the maximum distance between all pairs of vertex subsets with cardinality $ s $ of $ G $. When $ s = 1 $, the conditional diameter $ D(G; s) $ is just the diameter $ D(G) $. The authors in [18] characterized the graphs with the maximum Wiener index among all graphs with diameter $ D(G) = n-c $, where $ 1\le c\le 4 $. In this paper, we will characterize the graphs with the maximum Wiener index among all graphs with conditional diameter $ D(G; s) = n-2s-c $ ($ -1\leq c\leq 1 $), which extends partial results above.
Studies on bioactivities of Manuka and regional varieties of honey for their potential use as natural antibiotic agents for infection control related to wound healing and in pharmaceutical formulations
Authors: Dahiya Divakar , Mackin Caoimhin , Nigam Poonam Singh
Published: May 2024

Presently, most of the reported infections are of a bacterial origin; however, this leads to a limit within the literature and research around infections caused by fungal pathogens, which are now developing resistance to antibiotic medicines. Of the natural antimicrobial agents, honey has been observed with demonstrable and highly exploitable antimicrobial and infection control related to wound healing properties; therefore, it has been incorporated into many standard pharmaceutical formulations. Generally, these products utilize a pure sample of honey as a bioactive ingredient in a product which has been purposely designed for the convenience of application. This article aims to review information available from published reports on various bioactivities of a variety of medical-grade honey products, including manuka and other conventional non-manuka types sourced from different floral types and geographical regions. Additionally, this review highlights the antibiotic activities of various types of honey products tested against pathogenic strains of bacteria, yeast and fungi, and their applications in the formulation of healthcare products.
A natural adaptive process for collective decision‐making
Authors: Brandl Florian , Brandt Felix
Published: May 2024

Consider an urn filled with balls, each labeled with one of several possible collective decisions. Now let a random voter draw two balls from the urn and pick her more preferred as the collective decision. Relabel the losing ball with the collective decision, put both balls back into the urn, and repeat. Once in a while, relabel a randomly drawn ball with a random collective decision. We prove that the empirical distribution of collective decisions produced by this process approximates a maximal lottery, a celebrated probabilistic voting rule proposed by Peter C. Fishburn. In fact, the probability that the collective decision in round
n is made according to a maximal lottery increases exponentially in
n. The proposed procedure is more flexible than traditional voting rules and bears strong similarities to natural processes studied in biology, physics, and chemistry as well as algorithms proposed in machine learning
