The paper examines the rise and fall of the Golden Triangle opium-producing region, by focusing on local economic and social conditions, as well as international factors that have affected opium production in Myanmar (formerly Burma), Laos, and Thailand. By 1970, the Golden Triangle countries produced 70 percent of the world’s opium, but even in the late 1990s, the figure remained 66 percent, and only today has the region become less significant, as a result of the combination of parallel but non-interacting processes. Along with the reasons for the region’s rise, its decline and prospective trends are examined.
Water Resources Balanced Scheduling Method Using Particle Swarm Optimization for Future Smart Cities
Authors: Li Pei , Zhang Hong , Yue Yanbing
Published: August 2022

In order to solve the problem of a balanced water resources operation more effectively, the improved particle swarm optimization (PSO) algorithm is applied to the optimization of water resources and a mathematical model is constructed of water resources to optimize the operation of cascading hydropower plants. The objective function of the model is to solve the optimal output process of each hydropower plant so as to maximize the total power generation during the operation period. The constraints of the model are water level, output, discharge, the water balance of the reservoir, and the water flow relationship between the reservoirs. The particle swarm optimization algorithm is used to optimize the water resources of cascade hydropower plants. The objective function is taken as the fitness function of the particle swarm and the particle flight speed is dynamically adjusted to the ultimate optimal point. The time dimension of optimal scheduling is taken as the particle space dimension to realize the calculation of the multi-stage process of the scaling period. On this basis, from the two aspects of local convergence improvement and PSO, we improve the resource balance scheduling process of the particle algorithm and improve the balanced scheduling of water resources. The results show that the power generation of cascading hydropower plants is 4.52 % higher than that of the conventional operation when using the PSO algorithm; the average annual power generation of cascading hydropower plants is increased by 2.0 %, the guaranteed output is increased by 1.9 %, and the average annual waste water is reduced by 1.6 %. The guaranteed degree of water supply of the reservoir during the operation period is reduced and the storage capacity of the reservoir at the end of the year is increased by 50 %. The feasibility and effectiveness of this method in the optimization of water resources balance are verified, which shows that this method can provide a new idea for the balanced operation of water resources.

Authors: Khairulazdan N. B. , Menon P. S. , Zain A. R. Md. , Berhanuddin D. D.
Published: August 2022

Silicon photonics technology is on its last hurdle to complete the system with active research on enhancing the light extraction efficiency of silicon. Silicon has a very poor radiative emission efficiency due to its indirect bandgap, thus making the probability of radiative recombination to be very low. The periodic quantum confinement structures such as photonic crystals (PhCs) can be tailored to increase the radiative recombination probability at the desired wavelengths. In this paper, we have optimized the silicon photonic crystal (Si PhCs) parameters to obtain luminescence at silicon bandgap and telecommunication wavelength using FDTD method. The extraction of photons is mostly conquered in the silicon structure that has lattice constant, a: 480 nm with radius, r: 140 nm and a: 500 nm with r: 160 nm. We have also observed the emissive photon luminescence that emerges in the most stable state of optical communication wavelength at 1310 nm.

Published: August 2022

In this paper, a comparative study between four OLEDs devices is carried out. The bi- layers device (A) (consists of) Hole Injection Layer (HIL)/Electron Transport Layer (ETL), the multilayer device (B) (consists of) HIL Layer/Hole Transport Layer (HTL)/ETL Layer. The influence of the hole transporting material on the performance of the three layers OLEDs was investigated. Three different HTL materials were used: α- NPD, TAPC and p-TTA with the same electron transporting material as Alq3; (these holes transport material consists the devices (B), (C) and (D) respectively). The carrier injection, Langevin recombination rate, singlet exciton density and the power of luminescent are demonstrated. The simulation results shows that the insertion of a thin HTL layer between HIL and ETL layers increases the characteristics of the device (B)as: 6.19.1025 cm-3s-1 of the Langevin recombination rate, 1.16.1015cm-3 of the singlet exciton density and 0.04232 W/μm2 of the luminescence power. Moreover, the insertion of TAPC as HTL material gives rise to 1.36.1026 cm-3s-1 of the Langevin recombination rate, 2.1015cm-3 of the singlet exciton density and 0.075 w/μm2 of the luminescence power.
Structural, optical and electrical properties of anhydrous GdCl3 doped PEO polymer electrolyte films
Authors: Arasakumari M.
Published: August 2022

GdCl3 doped PEO polymer electrolyte films were prepared using solution casting technique. XRD patterns, FTIR spectra and optical absorption studies confirm an amorphous nature and the formation of the polymer electrolyte films. The ionic conductivity increases with the GdCl3 content and the maximum value at room temperature is about 1.8310-2 S/cm for 20 mol% GdCl3doped PEO film. This value is more than two orders of magnitude larger than the ionic conductivity of NASICON type Gd-doped solid electrolytes and other polymer electrolytes. The results suggest that the Gd3+ doped PEO polymer electrolyte films are good candidates for future electrochemical devices.

Published: August 2022

Applying advanced technologies such as computer vision is highly desirable in seed testing. Among testing needs, computer vision is a feasible technology for conducting seed and seedling classification used in purity analysis and in germination tests. This review focuses on seed identification
that currently encounters extreme challenges due to a shortage of expertise, time-consuming training and operation, and the need for large numbers of reference specimens. The reviewed computer vision techniques and application strategies also apply to other methods in seed testing. The review
describes the development of machine learning-based computer vision in automating seed identification and their limitations in feature extraction and accuracy. As a subset of machine learning techniques, deep learning has been applied successfully in many agricultural domains, which presents
potential opportunities for its application in seed identification and seed testing. To facilitate application in seed testing, the challenges of deep learning-based computer vision systems are summarised through analysing their application in other agricultural domains. It is recommended
to accelerate the application in seed testing by optimising procedures or approaches in image acquisition technologies, dataset construction and model development. A concept flow chart for using computer vision systems is proposed to advance computer-assisted seed identification.

Published: August 2022

Defect-free machining of materials and products with a strictly organized anisotropic structure (polymer composite materials), with an uneven change in physical and mechanical properties throughout the volume (synthegran) or with high strength properties (artificially grown superhard ruby and leucosapphire crystals) is either impossible or not economically feasible on modern CNC technological machines. The reason for this is the lack of information about the power parameter, e.g., the machining force and torque. Therefore, the use of the developed adaptive mechatronic mechanism (AMM) module, which implements parametric stabili-zation of the power machining parameter in an open-loop control system, was an effective solution to this technological problem.An analysis of the issue state in the field of mechatronic and intelligent machines has shown that to date, mechatronics as a science sys-tematically combines mechanics, electronics,and informatics (computer science). Moreover, the term informatics indirectlyreflects another component of mechatronics –automation. In this regard, two main methods of automatic control are considered: by deviation in a closed system with feedbackand by disturbance in an open system without feedback on the controlled parameter.Examples of open-loop systems with disturbance control, in which the “disturbance compensation principle” is implemented, are given. This method cannot be replaced in the absence of sensors –sources of information about physical processes in technological machines for various purposes, for example, in machine tool building, biomedicine, nuclear and military technology. As a rule, in all these ma-chines there is a reciprocating movement of the working body (tool).The information model of the AMM module presented in the article reflects its main elements and characteristics, including driving forces (electromagnetic and electrodynamic), a ball-bearing screw mechanism, a fixed (unmovable) stator with a field winding and a movable armature with armature winding.The place of this article in the general system of scientific research on the formulated new scientific direction “Mechatronic and intelligent technologi-cal machines”is shown. This articleis an introduction to this scientific direction, when automatic regulation “by disturbance”is per-formed in a mechatronic machine, i.e., the principle of disturbance compensation is fulfilled.

Published: August 2022

The study of the LoRaWAN method applicationperformance models intheIoT networks, which is currently being intensively developed, improved and is an important component of the information society. LoRa is a new long-range, low-power wireless technology that is key to building IoT networks around the world. Unlike other wireless technologies, the signal range and autonomy are enormous. Unlike GSM networks, it does not require bulky equipment with a high level of radiation.Itcan be easily used in places with mass construction without harm to human health. Two main scenarios for modeling performance improvement were investigated. Based on the results of the research, it is concluded that doubling the bandwidth effectively doubles the baud rate, and increasing the bandwidth reduces the sensitivity of the receiver, while increasing the propagation factor increases the sensitivity of the receiver. It is shown that by slightly changing the ACK procedure, it is possible to significantly improve the system performance in terms of packet delivery factor, system capacity, and energyefficiency. Conversely, it is determined that other system parameters are already well configured.

Published: August 2022

Objectives: The current study was conducted on adult male models to assess the impact of the Syzygium aromaticum (clove) extract on male fertility factors and oxidative stress after torsion/detorsion using the intrauterine insemination (IUI) method. Materials and Methods: This experimental study was performed on 56 adult male Wistar rats including 28 males and 28 females. The male subjects were randomly assigned to four groups of sham (G1), 4 hours of testicular torsion following a surgical torsion/detorsion (TD/G2), TD treated with the clove extract (4 mg/kg, orally/G3) 30 minutes before detorsion, and healthy subjects treated with the clove extract (4 mg/kg/G4). The levels of blood testosterone and some oxidative stress indices were investigated in the testis tissue. In addition, some sperm parameters were evaluated, including the concentration, motility, and morphology of the sperm. Finally, the fertilization potential of adult female rats was assessed through the IUI method. Results: The histological evaluation revealed considerable adverse changes in the G2 in comparison with the sham group. The serum levels of testosterone, and glutathione peroxidase, and superoxide dismutase meaningfully reduced in the testis of rats in the G2. In addition, the malondialdehyde level was significantly higher during the ischemia although all the mentioned changes improved in the treated groups. Nonetheless, the sperm quality and fertility power considerably reduced in the G2 compared to the sham group. Conclusions: The results of the current experimental study demonstrated that the testicular torsion/detorsion has an adverse impact on the testis function and decreases the fertilization potential, and finally, treatment with the clove extract can improve these adverse changes.

Published: August 2022

Objectives: To evaluate the in vitro fertilization success rate by transferring top- versus low-quality embryos. Materials and Methods: This prospective cohort study was conducted on 199 infertile women. Ninety-nine patients underwent an agonist cycle (70 fresh embryo transfer [ET] and 29 frozen ET), and 100 patients received an antagonist cycle (28 fresh ET and 72 frozen ET) in the infertility department of a tertiary university-based hospital between May 2019 and March 2020. The blastocysts classified as AA, AB, and BB, as well as AC, BC, and CC were considered as top- and poor-quality embryos (TQE and PQE). The study outcomes were biochemical and clinical and determined the rate of pregnancy. Results: The average age of the participants was 32.44±5.25 years old. Women with TQE were significantly younger than those with PQE (31.35±4.97 vs. 34.09±5.27, P<0.001). In addition, the duration of women’s infertility was significantly (P<0.001) correlated with the embryo’s top quality. A positive β-human chorionic gonadotropin was detected in 12.6% (n=25) of women while clinical pregnancy was investigated in 8% (n=16) of them. The fetal heart rate was detected in 7.5% (n=15). Eventually, the clinical (P=0.020) and determined (P=0.030) pregnancy rates significantly differed between two study groups with a higher level in the TQE group. Conclusions: It seems that TQP transfer should be the first recommendation for infertile women, but when the double-embryo transfer (DET) is needed according to the patient’s condition, she should be informed that the quality of the second embryo may have an adverse impact on pregnancy consequences.

Published: August 2022

Producers in the Western Cape province of South Africa are looking towards a push-pull strategy to reduce oviposition damage to plums by western flower thrips (WFT). White clover, Trifolium repens L., a favoured host plant of WFT, was investigated as a possible trap crop to provide the “pull” element. The attractiveness of collected volatiles of white clover flowers and of unopened (balloon stage) and open plum (Prunus salicina Lindl. cv. Sapphire) blossoms to WFT females was determined, using a Y-tube olfactometer. E-β-Farnesene, a known attractant for WFT, was included as positive control. Clover flower and open plum blossom volatiles exhibited statistically significant attraction of 69% and 71%, respectively, to WFT females. E-β-Farnesene and balloon stage plum blossom volatiles attracted 63% and 65% of WFT, respectively. When compared directly, 69% of WFT females chose the arm with the plum blossom volatiles over the clover flower volatiles. The clear preference shown by WFT for plum blossom volatiles indicates the use of a semiochemical to deter WFT from the plum blossoms would be required to enhance the efficacy of white clover as a trap crop in a push-pull strategy.

Authors: Gulcan Nazligul
Published: August 2022

Purpose- In this study, the effect of global economic policy uncertainty on crude oil prices is investigated.
Methodology- In the study, which considers the Global Economic Policy Uncertainty (GEPU) Index as an indicator of global economic policy uncertainty and the American WTI crude oil spot and forward prices for crude oil, the data set consists of monthly data for the period January 1997-April 2022. These data were analyzed by Breitung and Candelon's (2006) frequency causality test.
Findings- According to the results of Breitung and Candelon's (2006) frequency causality test, only long-term causality relationship was found from GEPU to American WTI crude oil spot and futures prices. In addition, it is seen that there is no causality relationship from American WTI crude oil spot prices to GEPU in short-term, mid-term and long-term while there is only long-term causality from American WTI crude oil future prices to GEPU.
Conclusion- It is thought that economic policy uncertainty tends to affect crude oil prices due to differences in demand. In line with these results, it becomes important for investors to consider the GEPU Index and the economic conditions affecting this index within the scope of their hedging strategies.

Tasks and technology are reciprocally related since the integration of technology can benefit task-based language teaching (TBLT) implementation. This study investigates students’ speaking performance, learning experiences, and perceptions in a speaking course specially designed with video recording activities involving online audiences based on the principles of TBLT. Thirty-eight undergraduate students majoring in English and enrolled in the speaking class served as the respondents. The data were collected through speaking tests, Likert scale questionnaires, and interviews. The findings indicated that the students developed their speaking performance after experiencing speaking class through a computer-assisted language learning (CALL)-mediated TBLT with video recording activities. They were also able to find their strengths and weaknesses by watching their own video recordings on YouTube. The findings also showed that the students had positive learning experiences and perceptions of video recording activities with online audiences on YouTube. Nevertheless, a further investigation of the online interactions toward the use of tasks and digital learning platforms with online audiences is highly advised.

Published: August 2022

The pandemic has intensified issues faced by the journalism community in Malaysia. This study is an attempt to help the media industries upskill themselves in terms of the written discourse. This study describes the rhetorical structures in Malaysian newspaper reports, namely The Star, in terms of the rhetorical moves and steps by using the genre theory, corpus-based discourse analysis and corpus analysis. MyCORONAS (Malaysian Corpus of Online Newspaper Articles) corpus of 90 selected news reports consisting of crime news (TSC), environmental news (TSE) and political news (TSP) was compiled and analysed quantitatively and qualitatively to identify the frequency, functions, and patterns of rhetorical moves. The findings identified a nine-move structure for the newspaper reports. The nine-move structure consists of five optional moves and four obligatory moves. Variations in the use of the steps were observed within the sub-genres. Additionally, based on the functions of the moves, it was found that the newspaper report is a hybrid genre with various communicative functions. Based on the patterns of move distribution, the dispersion value shows that the moves are tightly clustered. To conclude, the findings of this study will heighten the awareness of ESP learners on the importance of using appropriate rhetorical moves to write a newspaper report which will help the journalism industries reform themselves during the pandemic.

Published: August 2022

The tourism industry is one of the fastest-growing businesses in Indonesia, especially in Bali which contributes local and national economies. As most of the time English is used to carry out businesses, mastering English plays a significant role in their economic improvement. This study is intended to analyze the specific needs for English in the local tourism industry to prepare a need analysis of English language training for hotel and restaurant employees to empower the local community. The data for this mixed-method design study were taken a set of questionnaires on the needs, functions, and problems of using English in the tourism industry distributed to 36 respondents, observation, and interviews with employees as students and administrators. The collected data were analyzed using Katz’s (2009) simple non-parametric statistics and descriptive-interpretatively narrated. The findings show that most employees consider speaking to be the most important skill to function in their routine work because they need to guide, interact and communicate with (potential) customers, in particular, with foreign tourists visiting tourist attractions throughout the Mushroom Bay area, Nusa Lembongan. Concerning the use of English, they mostly employed English for general conversations, for providing services, and for giving information. The challenges they face in using English include inappropriate words and expressions usage in speech, being unable to understand foreign accents, having inadequate vocabulary in reading, and a lack of grammar knowledge in writing. These findings are used as the basis for developing course plans in English language training for small hotel and restaurant employees.
Effects of presentation delivery rate on errors in simultaneous interpreting: A pilot study
Authors: Arum Aulia Addinillah
Published: August 2022

Although the success of information rendition in simultaneous interpreting (SI) is susceptible to many factors, the speed of the source speech (SS) is perceived as one of the most challenging problem triggers. However, previous studies that examine the effects of SS in SI have reported different results. Therefore, this study aims to examine the effects of normal and fast source speech rates on simultaneous interpreting performance through error analysis. In this pilot study, seven error categories are employed, i.e., segment omission, word-and-phrase level omission, addition, unfinished sentence, filled pause, and long pause, which are derived from error classifications by Barik (1971). The first four categories are part of linguistic errors, whereas the last three categories are part of paralinguistic errors. Two videos with a speed of 124-wpm (words per minute) and 184-wpm were used as the source speeches and three professional interpreters with more than seven years of experience were recruited as research participants. It is revealed that the fast speech rate has increased the frequency of errors. Additionally, segment omission appears to be the category mostly impacted by SS speed. Therefore, the result of this study suggests interpreters’ training institutions pay more attention to coping tactics learning and acquisition in their courses.  Nevertheless, more replication studies are still required to verify this finding.
Profiling physiotherapy students’ interactions patterns in history taking
Authors: Kartika-Ningsih Harni , Djawas Faizah Abdullah
Published: August 2022

In physiotherapy education, history taking – in which a physiotherapist interacts with a patient to determine a prognosis – requires a set of communication skills which can be challenging for most student physiotherapists. One way to better understand the struggle that the students face is to examine the language and function of the interactions they use. This paper aims to investigate the way students perform their communication skills in history taking role-play. This study employed a qualitative discourse analytic method following the interpersonal discourse of NEGOTIATION, genre and register frameworks from the systemic functional linguistics. The data were obtained from a recorded students‘ role-play for their final assignments in a physiotherapy class. These data were then analysed by following the discourse analytic frameworks to map the structures and function of their interactions. The findings reveal that the students structure history taking stages similarly, while the length of exchange structures they build to gather information show differences in which skilled students tended to be more extensive in the interactions. The findings suggest that making explicit of the stages and move options may provide better awareness of the available choices the students can have in the history taking interactions.

Learning languages is inevitably related to one’s learning culture and patterns. Despite the existence of different language learning strategies in Indonesia, students’ achievements in general show unsatisfying facts. Several learning patterns have the potential to stymie foreign-language learning at particular educational levels. Those learning patterns are the accumulation of a long traditions and practices in teaching and learning of foreign languages. This study examined the practices of teaching and learning French as a foreign language at two universities in Indonesia. These institutions were selected based on their approaches to teaching and learning the language; one employs a pedagogic approach, while the other applies a generalist approach. Data were collected through in-depth interviews with nine students and six lecturers, as well as observation of four classes between March 2016 and October 2017. The data were subsequently selected and analyzed with a didactic of foreign language methodology. The methodology was based on a post structural paradigm with an emphasis on intertextuality and interdiscoursivity. This method implied the approach to discourse analyses referred to the French perspective. Results from the analysis showed that the universities tended to teach French with a repetitive and uniform approach. The most prominent didactic technique was rote memorization through mnemonics, which permeated almost all aspects of learning the foreign language. The failure to combine this technique with other learning strategies stymied students' efforts to learn the language.

Communication using English in Indonesia is challenging, especially when English is not used frequently. It’s happen to some area where English is only taught as mandatory subject in high schools. Madura is one of island in East Java that has unique characteristic, especially in the native language. This study aimed to analyze the misplaced of English word stress done by Madurese students and to find out the reason why they frequently misplace the word stress. A questionnaire and recording were used to collect data about students’ background identity and to record the students’ voice in pronouncing English words. The data were analysed by using qualitative research design to find out the causes of word stress misplacement. The findings revealved that the influence of mother language, motivation, attitude, and age are the most influential factors that generate students in misplacing the word stress. Besides, the lack of pronunciation training and practice done by teachers in their high school was also generating factors for students in pronouncing incorrect word stresses.
The Affective Triad: Smartphone in the Ethnographic Encounter
Authors: Jovicic Suzana
Published: August 2022

“Hanging out” and establishing “rapport” is an essential part of the ethnographic encounter in anthropology. But what happens when the smartphone, seemingly a distraction from the relationship in the making, creates a wall between the anthropologist and the interlocutor? While smartphones have been widely explored as a media technology used by the interlocutors, or as research tools, their affective grip on the researchers themselves has received less attention to date. Based on ethnographic fieldwork conducted with visitors of two youth centers in Vienna, Austria, in 2019, I argue that the moment when the smartphone becomes part of the affective triad, alongside the researcher and the interlocutor, also presents a window on the entanglement of digital technologies with everyday life. Moreover, affective ripples emerging from such irritations also expose underlying assumptions about how ethnographic encounters should ideally proceed and what constitutes rapport and “good” ethnographic relationships, seemingly a prerequisite for successful ethnographies. Hence, affective entanglements and irritations that arise in this context are not disturbances to be discarded or smoothed over in the ethnographic narratives. While the smartphone appears to impair the ethnographic encounter at first, its designed porosity allows the researcher to develop a particular sensitivity to issues of rapport, consent, and privacy, and to negotiate the space of potentiality of ambiguous, door-like situations, thus becoming a methodological blessing rather than a curse.

The article analyzes the journalist’s personal brand (PB). The article aims to discover the most essential characteristics of a journalist’s PB, which make it possible to shape its success as part of the media. Special attention is paid to developing a journalist’s PB through social media. We used the search and analytical research methods - to identify scientific developments on a given topic, concretization - to detail and systematize scientific knowledge, abstraction - to distinguish the components of PB, content analysis - to study specific PB of media personalities, and extrapolation - to formulate the characteristics of a journalist’s PB. A journalist’s PB covers more characteristics than a media brand, including personal preferences, unusual circumstances, the emotional component, advantages and disadvantages of communication with the audience. Individual characteristics of PB are an image with which a journalist conveys the sense, declares principles and interests, strengths and weaknesses, demonstrates individual qualities and attitude to events in the world that belong to a media resource, and maintains one’s reputation. The image of a journalist’s PB does not always correspond to the genuine person. Accounts in social media are part of PB. PB includes visual, behavioral, and verbal components.
Theoretical framework media and political economy of communication
Authors:   Instituto Politécnico Nacional. Escuela Superior de Economía, Mexico, Villalobos-López José Antonio
Published: August 2022

This article is presented with a deductive method orientation, with a paradigm of hermeneutic order, based on experience, carried out under an exclusively qualitative approach, which will serve as a scaffold for a next study of digital media. Communications are a means or mechanism of organization for coexistence in society. The political economy of communication has its origin in the theories or critical approaches of Frankfurt and cultural studies, which has analyzed the role of the owners or concessionaires of large radio and television corporations, highlighting the bias they have given to the dissemination of information and culture, orienting it towards the defense of their ideology or their commercial interests, thus leading to the alienation and training of large masses of audience. In these modern times, the massification of the media is the result of technological convergences, where three disciplines or spaces are at work: information technology, telecommunications and the Internet, which is the axis or center of the new communications ecosystem. Social networks allow feedback between sender and receiver of news, transforming the unidirectional communication process provided by conventional media.
Adaptive Learning Based Whale Optimization and Convolutional Neural Network Algorithm for Distributed Denial of Service Attack Detection in Software Defined Network Environment

Published: August 2022

SDNs (Software Defined Networks) have emerged as a game-changing network concept. It can fulfill the ever-increasing needs of future networks and is increasingly being employed in data centres and operator networks. It does, however, confront certain fundamental security concerns, such as DDoS (Distributed Denial of Service) assaults. To address the aforementioned concerns, the ALWO+CNN method, which combines ALWOs (Adaptive Learning based Whale Optimizations) with CNNs (Convolution Neural Networks), is suggested in this paper. Initially, preprocessing is performed using the KMC (K-Means Clustering) algorithm, which is used to significantly reduce noise data. The preprocessed data is then used in the feature selection process, which is carried out by ALWOs. Its purpose is to pick out important and superfluous characteristics from the dataset. It enhances DDoS classification accuracy by using the best algorithms.  The selected characteristics are then used in the classification step, where CNNs are used to identify and categorize DDoS assaults efficiently. Finally, the ALWO+CNN algorithm is used to leverage the rate and asymmetry properties of the flows in order to detect suspicious flows specified by the detection trigger mechanism. The controller will next take the necessary steps to defend against DDoS assaults. The ALWO+CNN algorithm greatly improves detection accuracy and efficiency, as well as preventing DDoS assaults on SDNs. Based on the experimental results, it was determined that the suggested ALWO+CNN method outperforms current algorithms in terms of better accuracies, precisions, recalls, f-measures, and computational complexities.
