A comparative analysis of the performance of various GNSS positioning concepts dedicated to precision agriculture
Authors: Kowalczyk Wiktoria Zofia , Hadas Tomasz
Published: February 2024

Automated guidance systems for precision agriculture rely on Global Navigation Satellite Systems (GNSS) and correction services for high accuracy and precision in field operations. This study evaluates the performance of selected GNSS positioning services for precision agriculture in a field experiment. We use three correction services: SF1, SF3, and RTK, which apply varying positioning concepts, i.e., Wide Area Differential GNSS, Precise Point Positioning, and Real-Time Kinematics, respectively. The tractor is autonomously steered along multiple predefined paths located in open-sky areas as well as near the heavy tree cover. The reference route of the vehicle is determined by classical surveying. Tractor trajectories, a SF1 and SF3 corrections, are shifted from predefined straight paths, unlike in the case for RTK. Offsets of up to several decimeters are service- and area-specific, indicating an issue with the stability of the reference frame. Additionally, the varying performance of the correction services implies that environmental conditions limit the precision and accuracy of GNSS positioning in precision agriculture. The pass-to-pass analysis reveals that SF1 improves the declared accuracy, while SF3 is less reliable in obstructed areas. RTK remains a stable source for determining position. Under favorable conditions, the pass-to-pass accuracy at 95% confidence level is better than 11.5 cm, 8.5 cm, and 4.5 cm for SF1, SF3, and RTK, respectively. In the worst-case scenario, the corresponding accuracies are: 25.5 cm, 65.5 cm, and 22.5 cm.

Die Aktualisierung des Lebenspotentials ist persönlichkeitsfördernde Aktivität. Ausgehend vom Schemabegriff nach Piaget (1936) und dessen Weiterentwicklung nach Vergnaud (1985; 2000) will ich deren strukturellen wie funktionellen Aspekte beschreiben. Meine Hauptthese lautet: Die Aktualisierungstendenz drückt sich in einer Gesamtheit von Verhaltensweisen aus, deren Teile (Ziel, Unterziel, Phasen, Begriffe, Aktionstheoreme, Inferenzen) auf der Repräsentationsebene in Begriffen, Bildern und Szenen abgebildet werden. Diese Elemente besitzen eine prozessuale und tendenzielle Logik, die sowohl der mikrogenetischen Entwicklung als auch dem durch die Beziehungserfahrung geförderten therapeutischen Prozess gemeinsam ist.
Psychotherapie als Prozess der Anerkennung
Authors: Spielhofer Hermann
Published: February 2024

Psychotherapie, soll sie wirksam sein, besteht in der gegenseitigen Anerkennung von Therapeut und Klient und in der Folge in der Anerkennung und Wiedererlangung des eigenen Begehrens durch den Klienten. Für Rogers waren stets die Einstellungen und Haltungen des Therapeuten, sein Beziehungsangebot wesentlich für das gedeihliche Klima in der Therapie. Daneben ist jedoch für den Autor das Beziehungsangebot des Klienten sowie dessen Rollenzuschreibungen an den Therapeuten ein wichtiger Aspekt in der Therapie. Im Rahmen des gemeinsamen Übertragungs-Gegenübertragungsprozesses wird eine Atmosphäre, ein interaktioneller Raum geschaffen, in dem das abgewehrte organismische Erleben in Form von unbewussten Inszenierungen und maskierten Botschaften, gleichsam „zwischen den Zeilen“ einfließen kann. Damit wird die Dyade aufgebrochen durch ein Drittes. Durch die Aufhebung in den gemeinsamen Sinn- und Verstehenshorizont, in die symbolische Ordnung der gemeinsamen Sprache entsteht eine triadische Struktur, die es ermöglicht, die affektive Verstrickung in der Dyade aufzulösen. Durch die Symbolisierungdes abgewehrten organismischen Erlebens, durch die (Wieder-)Einführung in die gemeinsame Kommunikation erhält die Sprache eine gestaltende Kraft für die Ausformung und inhaltliche Bestimmung unseres Erlebens wie unserer Bedürfnisse und emotionalen Bewertungen. Durch die gesellschaftlich vorgegebene Semantik und Syntax unserer Sprache kann die Wahrheit des Begehrens oder des organismischen Selbst aufgedeckt oder auch verschüttet werden, und Psychotherapie hat damit die Aufgabe, die Begriffe und sprachlichen Zeichen auf ihren aufklärerischen und emanzipatorischen Gehalt hin kritisch zu überprüfen.

Cereal yield forecasting in semi-arid region of Algeria using MODIS-NDVI
Authors: Boulaaras Hakima , Bouregaa Tarek
Published: February 2024

The prediction of cereals yields today is very important for global food security and helps decision-makers in the import-export operations of countries, especially with the rise world population. The advent of remote sensing technologies in precision farming systems has made cereal yield predictions possible, providing valuable insights into the temporal and spatial variations in cereal conditions across both large and small-scale crop lands. Among the various vegetation indices used to analyze these conditions, the normalized difference of vegetation index (NDVI) has emerged as a key indicator. The main objective of this study is to evaluate the possibility of using MODIS-NDVI data to forecast the yield of cereal crops (wheat and barley) in semi-arid region of Algeria (Setif). Additionally, identify the optimal timing for reliable and accurate crop yield forecasts. The remote sensing data utilized in this study covered the growing seasons from February to June, from 2002 to 2022. The results indicated a strong correlation between cereal grain yield and NDVI from late February to mid-March, with R² values ranging from 0.55 to 0.82 for the two cereal species. The RMSE of the NDVI based prediction model ranged from 0.01 t ha-1 to 0.276 t ha-1. The approximate average increase in the grain yield of barley and wheat lies between 0.659 to 0.746 t ha-1 with an increase of 0.1 in NDVI value. These results demonstrate the effectiveness of using MODIS-NDVI data for cereal yield forecasting in semi-arid region of Algeria, offering valuable predictions two to three months before the harvest.
Mark Z. Danilevsky's "House of Leaves": the Poetics of Simulacra
Authors: Novikau Artur Viktorovich
Published: February 2024

The object of research of this article is a novel by Mark Z. Danilevsky's "House of Leaves" in the context of Postmodernism. The subject of the study is the concept of a simulacrum, which appears in the novel "House of Leaves" as one of the funding components of the poetics of the work. The "House of Leaves" is considered from the position of postmodern sensitivity, in which Danilevsky deliberately blurs the boundaries between habitual space and hyperreality, real and unreal, fact and fiction. A similar effect is achieved through the simulacrum based on the novel – the short film "The Nevidson Film" – which was originally programmed by Danilevsky to expand into reality, to capture reality, that is, to limitless expansion of simulation through both material media (books) and the Internet. As a result of the proliferation of simulation within the work, the poetics of the novel text itself undergoes mutation, where genre mixing occurs, and mutually subordinate relations are established for the participants of author-reader communication due to the features of novel poetics. The text based on the simulacrum is absorbed by the simulation and eventually becomes a simulacrum due to the continuous formation and spread of the simulation. As a result, the language environment turns into a means of control, manipulation, subordination, both of the author and the recipient: the totality of simulation replaces reality and includes the perceiving consciousness in its own boundless becoming.
Payload Optimization for EnVision Mission Using an Electric Propulsion Module for Interplanetary Transfers
Authors: Valencia Sebastian
Published: February 2024

This paper presents a study on the feasibility of using electric propulsion (EP) for interplanetary transfer in the context of an Earth–Venus mission. Extensive research has been conducted on EP modules for Mars missions, demonstrating their potential for faster mission times and greater flexibility compared to all-chemical propulsion (CP) systems. However, there is a notable gap in our understanding regarding EP systems for Venus missions, despite the unique and challenging environment that Venus presents. This study aims to bridge that gap by evaluating the performance of an EP module compared to a conventional all-CP spacecraft, which serves as the backup mission for the EnVision mission by the European Space Agency. The objectives of the study include identifying key drivers for the EP module’s preliminary design, analyzing tradeoffs and challenges associated with EP systems, and evaluating the feasibility of achieving payload mass delivery. The results reveal that the all-EP spacecraft delivers a higher payload mass compared to the all-CP EnVision mission, highlighting the superiority of EP over CP for interplanetary missions. This research provides valuable insights into the potential advantages of EP systems for future interplanetary missions and emphasizes the necessary design considerations when utilizing EP technology.
Image Recovery for Low Earth Orbit by Leveraging Turbulence and Light Curves
Authors: Kobayashi Daigo , Frueh Carolin
Published: February 2024

This paper shows a novel method to characterize human-made objects in low Earth orbit (LEO) using compressed sensing on light curve measurements. The proposed approach minimizes total variation to recover a resolved object image from a fully unresolved light curve and a so-called point spread function (PSF) map. The light curves are generated through numerical wave propagation, which considers atmospheric turbulence under anisoplanatic conditions. Subsequently, the light curve model is transformed into a linear measurement model to apply compressed sensing techniques. Notably, the sensing matrix is found to be a superposition of spatially variable PSFs, which significantly downsamples the ideal object image. The proposed approach robustly recovers clear images of objects in LEO, even with imperfect PSF map estimates and Poisson noise in the light curve measurement.
Precise Orbit Determination of the MESSENGER Spacecraft
Authors: Andolfo Simone , Genova Antonio , Del Vecchio Edoardo
Published: February 2024

The NASA MESSENGER mission explored Mercury for more than four years to investigate the properties of the planet. To safely operate in the harsh conditions around Mercury, the spacecraft was in a highly eccentric orbit with a low periapsis altitude. The radiation environment had a strong impact on the spacecraft orbit evolution because of the proximity of Mercury to the Sun. A detailed modeling of the nonconservative forces is then a key factor to enhance the precise orbit determination of the spacecraft. We present here refined models of the nonconservative forces, including thermal reradiation effects, that enabled significant improvements in the trajectory reconstruction. A crossover analysis based on the Mercury Laser Altimeter (MLA) data was carried out to cross-check the accuracy of the orbit determination results. The trajectories retrieved by using the refined spacecraft dynamical model provide reduced height misfit at crossover points, indicating a high-quality reconstruction. Our new solutions of the spacecraft orbits are then archived to be used as auxiliary information for the data analysis of other MESSENGER instruments.
Toward Automated Gust Load Alleviation Control Design via Discrete Gust Impulse Filters
Authors: Cavaliere Davide , Fezans Nicolas
Published: February 2024

In the context of active gust- and turbulence-load alleviation function design, control designers optimize the response of the closed-loop system to satisfy the relevant certification specifications (e.g., European Union Aviation Safety Agency (EASA) CS-25.341 and Federal Aviation Regulations (FAR) Part 25, Sec. 341). These include time-domain criteria specifying the peak response to discrete gusts as well as frequency-domain continuous-turbulence criteria. Both types of criteria cannot be easily considered simultaneously with commonly available control design software. A frequency-domain formulation of 1−cosine discrete gust criteria based on a low-order, parameterized linear filter is proposed and demonstrated on a publicly available gust load alleviation benchmark. One example demonstrates its application in combination with continuous-turbulence specifications, and in principle, it can also be combined with other relevant frequency-domain specifications, such as passenger comfort metrics. This technique is shown to work well, producing the desired results with a simple, systematic design procedure, and should help reduce the time and effort required to obtain satisfactory control specifications.
Numerical Investigation on Transpiration Cooling Performance of Oriented Porous Structure Under Local Block Conditions
Authors: Yang Yang , Zhang Bo , Fan Xueling , Zhao Rong
Published: February 2024

With the development of an active thermal protection system (TPS) for hypersonic vehicles, reliability improvement and weight reduction of TPS are key issues to be considered. In this paper, an oriented porous structure (OPS) is proposed to solve the local overheating problem in transpiration cooling. The transpiration cooling performances are investigated in a two-dimensional computational domain using a local thermal nonequilibrium model. The cooling mechanisms of OPS and uniform porous structure (UPS) under local block conditions have been numerically analyzed and compared. The results show that OPS leads to effective cooling of the overheated region by regulating the coolant flow behavior, especially in the case of serious block conditions. The maximum temperature reduction can be up to more than 200 K, and the maximum optimization rate can reach up to 23% compared to UPS. Moreover, OPS consumes less coolant and uses less driving force to deliver coolant when reaching the same peak temperature as OPS. This study shows that OPS has a better thermal protection effect in transpiration cooling, which can improve the reliability of TPSs, and that OPS can also achieve the lightweight of the aircraft.

Published: February 2024

Previous studies have shown that electrohydrodynamic (EHD) gas pumps are a viable alternative for traditional fans. In this study, it is further demonstrated that an EHD gas pump is ideal for cooling electronic components. To this end, four electronic components, which are individually mounted on each wall of a horizontal channel, are cooled by a two-stage EHD gas pump with aligned electrodes. Three heat dissipation rates are evaluated: 100, 200, and [Formula: see text]. To evaluate the performance of the EHD gas pump, the results are compared with those obtained without using the EHD pump. The present results show that an EHD gas pump can generally produce desirable cooling effects if used properly. The average surface temperature and maximum temperature on the electronic components cooled by the EHD gas pump with electrodes mounted on the horizontal walls are lower than those obtained with electrodes mounted on the vertical walls. Thus, it is important to consider the effect of electrode orientation in selecting an appropriate EHD gas pump for application in electronics cooling.

Hexane and ethyl acetate extracts were employed to carry out the research on the phytochemical and antibacterial activity of Hardwickia binata Roxb. To identify the components, present in the extract, the GC-MS technique was used for analysis. Functional groups of various extracts were identified using FTIR. The plant extract in hexane and ethyl acetate was evaluated for its ability to fight human pathogenic bacteria. The results of the phytochemical screening revealed that phenols, saponins, flavonoids, cardiac glycosides, steroids and tannins are present. The GC-MS data revealed that the ethyl acetate extract contained 25 bioactive substances. The extract of ethyl acetate showed good antimicrobial activity. S. aureus (16 mm) demonstrated the largest zone of inhibition when treated with 75 μg/mL of ethyl acetate extracts. As a result, this study provides data on the phytochemical constituents identified in both extracts. As a result, it may be employed in additional therapeutic applications in near future.

Published: February 2024

The experiments were done at two farms in Latvia. Primocane raspberries were weekly sprayed with solutions of ethanol extractions of microalgae species of Spirulina sp., Dunaliella sp. and Chlorella sp. in different concentrations from stages of shoot growth to fruit ripening. During the season, dynamics of the shoot growth, beginning of flowering and fruit ripening were recorded. After the treatments, productive length of the shoots, number of flower trusses and leaves per shoot, number of productive shoots per plot, chlorophyll index, average fruit weight and sugar content in the fruits were measured. Certain positive effects of the treatments with one or another algae extraction were observed, increasing plant height and the proportion of the productive part of the shoot, number of leaves and flower trusses per shoot and the chlorophyll index. Moreover, no negative effects of any tested treatments were observed. However, the positive effects differed in different farms and years. That can be explained by uneven growth of the plants in the farms, weed and disease spread, changing weather conditions. Therefore, we can conclude that since the results are strongly promising, further experiments in controlled environments using preparations of varied extraction types, microalgae species and different treatment protocols should be carried out.

Authors: Banerjee Amrita , Mitra Debanjan , Das Biswajit , Das Mohapatra Pradeep Kumar , Samanta Saptadip
Published: February 2024

Alpha amylases (EC 3.2.1.1.) hydrolyze polysaccharides like starch and glycogen to create oligosaccharides of different sizes by random cleavage of internal 1, 4-glucosidic linkages. These enzymes are produced by many different bacteria and fungi. In this investigation, α-amylase from Aspergillus flavus and Aspergillus oryzae was taken into consideration. Amino acid sequences and protein structure were retrieved from databases. Sequences of Aspergillus oryzae possess a high number of charged residues whereas Aspergillus flavus have a higher abundance of uncharged polar and hydrophobic amino acid residues. 3 common superfamilies were observed between both species. The alignment of sequences showed their similar conservative nature. Non-covalent intra-protein interactions like the salt bridge, aromatic-aromatic interactions, aromatic-sulfur interactions and cation-pi interactions helped to increase the stability of α-amylase of Aspergillus oryzae. The tunnels and cavities also help to increase the functionality and catalytic activity of α-amylase. This study will also be helpful for protein engineering.

Spectral Analysis of Splitting Signed Graph
Authors: Kumar Sandeep , Sinha Deepa
Published: February 2024

An ordered pair $\Sigma = (\Sigma^{u}$,$\sigma$) is called the \textit{signed graph}, where $\Sigma^{u} = (V,E)$ is a \textit{underlying graph} and $\sigma$ is a signed mapping, called \textit{signature}, from $E$ to the sign set $\lbrace +, - \rbrace$. The \textit{splitting signed graph} $\Gamma(\Sigma)$ of a signed graph $\Sigma$ is defined as, for every vertex $u \in V(\Sigma)$, take a new vertex $u'$. Join $u'$ to all the vertices of $\Sigma$ adjacent to $u$ such that $\sigma_{\Gamma}(u'v) = \sigma(u'v), \ u \in N(v)$. The objective of this paper is to propose an algorithm for the generation of a splitting signed graph, a splitting root signed graph from a given signed graph using Matlab. Additionally, we conduct a spectral analysis of the resulting graph. Spectral analysis is performed on the adjacency and laplacian matrices of the splitting signed graph to study its eigenvalues and eigenvectors. A relationship between the energy of the original signed graph $\Sigma$ and the energy of the splitting signed graph $\Gamma(\Sigma)$ is established.

Let X be the leaf classes space and X0 be the union of all open subsets of X homeomorphic to R or S1. In [2, Theorem 3.15] it is shown that if a codimension one foliation has a finite height, then the singular part of the space of leaf classes is homeomorphic to the prime spectrum (or simply the spectrum) of unitary commutative ring. In this paper we prove that the singular part of the space of leaf classes is homeomorphic to the spectrum of unitary commutative ring if and only if every family of totaly ordered leaves is bounded below.

Let G be a graph. A subset I′ of a vertex-set V (G) of G is called a J2-independent in Gif for every pair of distinct vertices a, b ∈ I′, dG(a, b) ̸= 1, N2 G[a]\N2 G[b] ̸= ∅ and N2 G[b]\N2 G[a] ̸= ∅. The maximum cardinality among all J2-independent sets in G, denoted by αJ2 (G), is called the J2-independence number of G. Any J2-independent set I′satisfying |I′| = αJ2 (G) is called the maximum J2-independent set of G or an αJ2 -set of G. In this paper, we establish some boundsof this parameter on a generalized graph, join and corona of two graphs. We characterize J2-independent sets in some families of graphs, and we use these results to derive the exact values of parameters of these graphs. Moreover, we investigate the connections of this new parameter with other variants of independence parameters. In fact, we show that the J2-independence number of a graph is always less than or equal to the standard independence number.

Authors: Alshayea Maryam Abdullah , Alsager Kholood
Published: February 2024

The main objective of this paper is to effectively define a new concept of the fabulous fuzzy set theory that is called m-polar Q-hesitant anti-fuzzy set and apply it to the BCK/BCI-algebras. The m-polar Q-hesitant anti-fuzzy set is an astonishing development of the combination between the m-polar fuzzy set and the Q-hesitant fuzzy set. However, we introduce knowledge of the m-polar Q-hesitant anti-fuzzy subalgebra, m-polar Q-hesitant anti-fuzzy ideal, closed m-polar Q-hesitant anti-fuzzy ideal, m-polar Q hesitant anti-fuzzy commutative ideal, m-polar Q-hesitant anti-fuzzy implicative ideal, and m-polar Q-hesitant anti-fuzzy positive implicative of BCK/BCI- algebras. In addition, we investigate several theorems, examples, and properties of these notions.

Published: February 2024

Let R be an associative ring and M a unitary left R-module. An R-module M is said to be uniserial if its submodules are linearly ordered by inclusion. A serial module is a direct sum of uniserial modules. In this paper, we bring our modest contribution to the open problem listed in the book of Alberto Facchini "Module Theory" which states that is any direct summand of a serial module serial? The answer is yes for particular rings and R-modules.

Determinants of Arrowhead Matrices over Finite Commutative Chain Rings
Authors: Jitman Somphong , Modjam Pornrudee
Published: February 2024

Arrowhead matrices have attracted attention due to their rich algebraic structures and numerous applications. In this paper, we focus on the enumeration of n × n arrowhead matrices with prescribed determinant over a finite field Fq and over a finite commutative chain ring R. The number of n × n arrowhead matrices over Fq of a fixed determinant a is determined for all positiveintegers n and for all elements a ∈ Fq. As applications, this result is used in the enumeration of n × n non-singular arrowhead matrices with prescribed determinant over R. Subsequently, some bounds on the number of n × n singular arrowhead matrices over R of a fixed determinant are given. Finally, some open problems are presented.

Authors: Taher Hunar , Dash Saroj Kumar
Published: February 2024

Let Tm be a Tribonacci sequence, and let the k-Pell sequence be a generalization of the Pell sequence for k ≥ 2 . The first k terms are 0, 0, ..., 0, 1, and each term after the forewords is defined by linear recurrence P (k) n = 2P (k) n−1 + P (k) n−2 + ... + P (k) n−k . We study the solution of the Diophantine equation P (k) n = Tm for the positive integer (n, k, m) with k ≥ 2. We use the lower bound for linear forms in logarithms of algebraic numbers with the theory of the continued fraction.
Looking at Two Ways of Constructing Quotient Hyper $BN$-algebras and Some Notes on Hyper $BN$-ideals
Authors: Cabardo Lyster Rey , Petalcorin Jr. Gaudencio
Published: February 2024

A hyper $BN$-algebra is a nonempty set $H$ together with a hyperoperation ``$\circledast$'' and a constant $0$ such that for all $x, y, z \in H$: $x \ll x$, $x \circledast 0 = \{x\}$, and $(x \circledast y) \circledast z = (0 \circledast z) \circledast (y \circledast x)$, where $x \ll y$ if and only if $0 \in x \circledast y$. We investigated the structures of ideals in the Hyper $BN$-algebra setting. We established equivalency of weak hyper $BN$-ideals and hyper sub$BN$-algebras. Also, we found a condition when a strong hyper $BN$-ideal become a hyper $BN$-ideal. Finally, we looked at two ways in constructing the quotient hyper $BN$-algebras and investigated the relationship between the two constructions.

Published: February 2024

In recent years, Mohanad transform, a mathematical approach, has drawn a lot of interest from researchers. It is useful for solving many engineering and scientific problems, such as those involving electric circuits, population growth, vibrational beams, and heat conduction. The Mohanad transform is defined and introduced in this study, along with its fundamental qualities,including linearity and convolution. It is also discussed in connection with other integral transforms and how it is used in derivatives. Additionally, we use the Mohanad transform to solve a few systems of ordinary differential equations (ODEs) and review its properties in this paper. Determining the concentration of a chemical reactant (material) in a series is a physical chemistry problem that we use in the application part. We achieve this by developing a model based on ordinary differential equations (ODEs) and then solving them using the Mohanad transform. This research proves that, with little computational effort, we can get the exact solutions of ordinary differential equations (ODEs) via the Mohanad transform. We used graphs and tables to show our answer.

Authors: Alshayea Maryam
Published: February 2024

This paper focuses on exploring restricted mathematical concepts within the domain of BCK/BCI-algebras, specifically delving into the intricate realm of Multi-polar Q-hesitant fuzzy soft implicative and positive implicative ideals. BCK and BCI-algebras are pivotal structures in mathematical logic and algebraic systems, finding widespread applications in fields like computer science and artificial intelligence. Our contribution lies in the introduction and thorough investigation of the innovative notions of multi-polar Q-hesitant fuzzy soft implicative and positive implicative ideals, uniquely tailored for BCK/BCI-algebras. These ideals exhibit exceptional flexibility in managing uncertain and hesitant information, serving as potent tools for modeling and solvingreal-world problems characterized by imprecise or incomplete data. This study rigorously defines and explores the foundational properties of multi-polar Q-hesitant fuzzy soft implicative ideals, underscoring their relevance and applicability within BCK/BCI-algebras. Additionally, we present the concept of positive implicative ideals, establishing their interconnectedness with multi-polar Q-hesitant fuzzy soft implicative ideals. Our investigation delves into these ideals’ algebraic and logical facets, offering valuable insights into their mutual interactions and significance within the context of BCK/BCI-algebras. To facilitate practical implementation, we develop algorithms and methodologies for identifying and characterizing multi-polar Q-hesitant fuzzy soft implicative and positive implicative ideals. These computational tools enable efficient decision-making in scenariosinvolving uncertainty. Through illustrative examples and case studies, we showcase the potential of these ideals in handling complex, uncertain information, demonstrating their efficacy in aiding problem-solving processes. This research contributes significantly to advancing BCK/BCI-algebra theory by introducing innovative mathematical structures that bridge the gap between fuzzy logic, soft computing, and implicative ideals. The proposed multi-polar Q-hesitant fuzzy soft implicativeand positive implicative ideals open new avenues for addressing real-world problems characterized by imprecision and uncertainty. As such, they represent a valuable addition to the field of algebraic structures and their applications.

Authors: AlRawashdeh Waleed
Published: February 2024

In this paper, we introduce and investigate a family of analytic functions, denoted by $\mathcal{F}(\Pi, \alpha, \beta, \lambda, \delta, \mu)$, defined by means of Horadam polynomials. For functions in this family, we derive the estimations for the initial Taylor-Maclaurin coefficients $|a_2|$ and $|a_3|$. Moreover, we obtain the classical Fekete-Szeg\"{o} inequality of functions belonging to this family.
