Authors: Habiburrahman
Published: September 2022

Setiap lulusan S1 keperawatan (NERS) harus dinyatakan kompeten pada Uji Kompetensi Ners Indonesia (UKNI) yang diadakan Kemdikbud untuk mendapatkan Surat Tanda Registrasi (STR) sebagai syarat bekerja. Tingkat kelulusan mahasiswa keperawatan dalam mengikuti UKNI sangat rendah jika dibandingkan dengan beberapa negara lain. Penelitian ini bertujuan mengidentifikasi faktor-faktor yang perlu dioptimalkan calon tenaga keperawatan dalam persiapan menghadapi UKNI dengan teknologi data mining. Data yang diolah dalam penelitian ini bersumber dari Appskep Indonesia, suatu startup yang bergerak di bidang pendidikan kesehatan, diantaranya try out dan bimbingan belajar UKNI. Appskep memiliki data kelulusan UKNI lebih dari 2000 pesertanya yang tersebar di seluruh Indonesia pada tahun 2021 dan 2022. Data tersebut dianalisis menggunakan Algoritma Apriori untuk menemukan rule-rule asosiasi yang terkait dengan kelulusan calon tenaga perawat dalam UKNI. Hasil dari pengolahan data peserta UKNI ini adalah ditemukannya beberapa set rule asosiasi yang mempengaruhi kompeten atau tidaknya calon tenaga perawat dalam UKNI. Rule asosiasi yang paling dominan adalah jika penguasaan materi keperawatan jiwa lebih dari 60 persen maka seorang perawat akan lulus pada UKNI, dengan support 55% dan confidence 100%.

Authors: AKTÜRK Tolga , ÇAKMAK Volkan
Published: September 2022

This study obtains some wave solutions of the B-type Kadomtsev Petviashvili equation by applying the modified exponential function method (MEFM). Due to the nature of the MEFM, two different cases are presented here, which we analyzed to obtain more of the solutions in this structure. More wave solutions can be obtained by analyzing different situations. When the resulting solutions are analyzed, hyperbolic, trigonometric, and rational functions are observed. It has been checked whether the solution functions found with Wolfram Mathematica software provide the B type Kadomtsev Petviashvili equation and graphs simulating the wave solution behavior with the determined appropriate parameters are presented.

Authors: Gittenberger Bernhard , Gołębiewski Zbigniew , Larcher Isabella , Sulkowska Małgorzata
Published: September 2022

An embedding of a rooted tree $S$ into another rooted tree $T$ is a mapping of the vertex set of $S$ into the vertex set of $T$ that is order-preserving in a certain sense, depending on the chosen tree family. Equivalently, $S$ and $T$ may be interpreted as tree-like partially ordered sets, where $S$ is isomorphic to a subposets of $T$. A good embedding is an embedding where the root of $S$ is mapped to the root of $T$.

We investigate the number of good and the number of all embeddings of a rooted tree $S$ into the family of all trees of given size $n$ of a certain family of trees. The tree families considered are binary plane trees (the order of descendants matters), binary non-plane trees and rooted plane trees. We derive the asymptotic behaviour of the number of good and the number of all embeddings in all these cases and prove that the ratio of the number of good embeddings to that of all embeddings is of the order $\Theta(1/\sqrt{n})$ in all cases, where we provide the exact constants as well. Furthermore, we prove some monotonicity properties of this ratio. Finally, we comment on the case where $S$ is disconnected.
A Counterexample to the Shuffle Compatiblity Conjecture
Authors: Kantarcı Oğuz Ezgi
Published: September 2022

The shuffle product has a connection with several useful permutation statistics such as descent and peak, and corresponds to the multiplication operation in the corresponding descent and peak algebras. Gessel and Zhuang formalized the notion of shuffle-compatibility and studied various permutation statistics from this viewpoint. They further conjectured that any shuffle compatible permutation statistic is a descent statistic. In this note we construct a counter-example to this conjecture.
Maximum Size of a Graph with Given Fractional Matching Number
Authors: Ma Tianlong , Qian Jianguo , Shi Chao
Published: September 2022

For three integers $n,k,d$, we determine the maximum size of a graph on $n$ vertices with fractional matching number $k$ and maximum degree at most $d$. As a consequence, we obtain the maximum size of a graph with given number of vertices and fractional matching number. This partially confirms a conjecture proposed by Alon et al. on the maximum size of $r$-uniform hypergraph with a fractional matching number for the special case when $r=2$.
Towards the Small Quasi-Kernel Conjecture
Authors: Kostochka Alexandr V. , Luo Ruth , Shan Songling
Published: September 2022

Let $D=(V,A)$ be a digraph. A vertex set $K\subseteq V$ is a quasi-kernel of $D$ if $K$ is an independent set in $D$ and for every vertex $v\in V\setminus K$, $v$ is at most distance 2 from $K$. In 1974, Chvátal and Lovász proved that every digraph has a quasi-kernel. P. L. Erdős and L. A. Székely in 1976 conjectured that if every vertex of $D$ has a positive indegree, then $D$ has a quasi-kernel of size at most $|V|/2$. This conjecture is only confirmed for narrow classes of digraphs, such as semicomplete multipartite, quasi-transitive, or locally semicomplete digraphs. In this note, we state a similar conjecture for all digraphs, show that the two conjectures are equivalent, and prove that both conjectures hold for a class of digraphs containing all orientations of 4-colorable graphs (in particular, of all planar graphs).

Published: September 2022

This study investigated the effect of peer tutoring on the achievement of students in ecology in colleges of education in the North-Western zone of Nigeria. The study adopted a quasiexperimental pretest, a post-test control group design. The sample of 128 students from two(2) colleges of education out of seven (7) colleges of education in Kano State from a population of 2900, form the intact classes for the study. Each intact class was randomly selected from NCE 1 Biology students, each arm containing 64 students. Ecology Achievement Test (EAT) was the instrument used in this study for data collection, it was adopted from NCE 1past moderated examination questions that comprise 40 multiple-choice expert-validated questions. The split-half reliability coefficients of EAT were established. Three research questions guided the study and three corresponding null hypotheses were tested at 0.05 level of significance. The experimental group was taught using peer tutoring while the control group was taught using the lecture method. A pretest was administered to both groups. The experimental group was taught ecology using peer tutoring, while the control group was exposed to the lecture method for a period of six weeks. The results showed that the Experimental group (Mean=31.6) perform better than the Control group (Mean=24.9). The result showed that males in the Experimental group achieved higher mean scores (Mean=31.89) than those in the Control group (Mean=23.55.9). Results showed that female students taught using peer tutoring (M = 31.34) perform better than those taught using the lecture method (M = 26.64). From the findings of the study, it was recommended that the Administrations of Colleges of Education in the northwest zone in Nigeria should enforce the use of a variety of approaches in teaching. Such an approach should include the use of social interaction and a cooperative learning approach, the use of lecture methods by teachers should be reduced. Rather, a constructivist approach that calls for social interaction among students should be a dominant approach.

HOMOMORPHIC ENCRYPTION IN 5IRE BLOCKCHAIN
Authors: MATTILA VILMA , DWIVEDI PRATEEK , GAURI PRATIK , AHBAB MD
Published: September 2022

With the advent of blockchain technology, decentralized system is gaining huge popularity as it provides a new solution for data storage and sharing as well as keeping privacy in place. Blockchains are of two categories; public and private. Public blockchains are permissionless, mostly used for exchanging and mining cryptocurrency, where anyone can join and thus exposed to the risk of a privacy breach. If the content is the transaction information, one might opt for not sharing these data in the public domain. One solution could be to encrypt the information, but that comes at the cost of losing the usability of the data. This paper investigates the security problem related to this passive adversarial activity and proposes a new technology that leverages the best parallel chain architecture of 5ire blockchain and homomorphic encryption (HE) so as to retain the advantages of a public blockchain without compromising the privacy of transaction information. We have coined the term 5ireHE for this encryption architecture. We achieve the security protection and integrity check of wallet data by enforcing the 5ireHE which is efficient.

The internal auditor must also audit the company’s strategic goals and verify its consistency with the company’s vision and mission as well as with the plan In addition to the necessity to involve internal auditors in training and qualification courses in the field of strategic auditing methods such as the SWOT analysis tool and to develop their scientific and practical skills.
THE WILL TO POWER AND OTHER FORCES ACCORDING TO NIETZSCHE
Authors: Ali Flhi Amal
Published: September 2022

In this research I dealt with the subject of (the will to power) and how the philosopher (Nietzsche) dealt with it. I wanted to stand in this research at an important question in Western philosophy, and is the idea of the will to power in Nietzsche the top of his critical pyramid? Is it the epitome of his revolutionary philosophy? Is it the principle and goal that man seeks to reach? Nietzsche sees that within man there is a force that pushes him to transcendence and transcendence above existence, and it represents the nature of the existing, represented by the will to power. We have sought in this research to shed light on the value aspects in Nietzsche’s philosophy and their relationship to the will to power and the meaning of this concept through its manifestation and its appearance in life, until it reaches its goal and purpose, which is to reach the perfect human or “Superman who transcends everything.”
IN SEARCH FOR IDENTITY IN POSTMODERN AMERICA: THE CASE OF DON DELILLO’S WHITE NOISE
Authors: Abid Al Ibrahim Haneen Sabah
Published: September 2022

This paper will discuss the negative effects of consumerism on people in the postmodern American society in Don DeLillo’s White Noise (1985). It will examine the threat of consumerism to humans through employing postmodern theories of Jean Baudrillard and Fredrick Jameson, and argues that consumerism physically and mentally affects individuals, depriving them of their individuality and assimilating them into a collective consumer society. On the physical level, people cannot avoid environmental and toxic dangers in their consumerist society, even white noises can harm them. Moreover, and most importantly, consumerism can cause people serious mental problems, leading people towards faulty perceptions about their own identities and their ultimate search for a hyperreality to compensate for their individualistic loss.
The Making of a Heroine: A Female Character as Portrayed in The English Patient By Michael OndaatjE
Authors: Shakir Zainab Sameer
Published: September 2022

This article discusses how women have significant abilities to cope with the difficulties of war times. They are not the weak and vulnerable victims who are thought to be. On the contrary, they have the power to control over many-sided fronts, like participating in the battlefield as nurses or activists for peace, or even fighters, as well as through the tasks and responsibilities assigned to them to protect and support their families during wartime. The researcher will examine the impact of war upon women. Like men, women suffer during wartime. They are being injured, tortured and killed. Yet, they are able to give examples of love and courage even in the difficult times of war. Hana is one of those women who lived during wartimes, she is supposed to have a beautiful life at the age of twenty one, but she finds herself in Italy taking care of the English Patient leaving all the chances of happy life behind to dedicate herself for becoming a nurse. Michael Ondaatje in his novel The English Patient (1992) has chosen the medical field for Hana for it is an important step in healing and treating the mentality before the body. The English Patient shows the life of women though wartime and it succeeds in depicting how Hana insists on living strongly
Community Research Extension Continuum in Urban Agriculture in an Urban Barangay of Northern Philippines

Published: September 2022

Urban Agriculture has always been an important part of society as it is responsible for producing essential food crops, which are essential in maintaining food security and nutrition. It also provides livelihood opportunities to many people. An important factor in farming and gardening is soil quality. Soils supply the essential nutrients, water, oxygen, and root support that our food-producing plants need to grow and flourish. This study aimed to analyze the chemical properties of the soil in Barangay Lucnab, Baguio City, as well as the presence of macronutrients and micronutrients. This research is important as it aims to assist the residents of Lucnab, given their present predicament of the low harvest and seemingly acidic soil, to maximize the nutrients already present in the farm and recommend the right amount of fertilizer and crops to plant to enhance productivity. And it is, therefore, the aim of this study to educate the community on how to maximize the potential of their farm. The research design used in this study was descriptive and experimental. The descriptive and experimental types of research sought to determine the characteristics of the soil sample in Barangay Lucnab through the manipulation of variables. They compared the results to a standard value. The sampling method used in collecting the soil was the zigzag sampling pattern. This method is adopted from the work of Ackerson (2018). Significant findings of this research revealed that the soil has low moisture content at values ranging from 27.26% to 33.60%. The soil is strongly acidic as the pH reading ranged from 4.1 to 4.83. Furthermore, the two sampling sites in Lucnab show a low organic matter with a value from 2.71% to 3.45%, while Purok 4A reveals a better nitrogen content. The levels of micronutrients such as phosphorous and potassium are above the optimum level, with the presence of micronutrients like zinc, copper, iron, and manganese. The results imply that the soil's acidity in Barangay Lucnab may affect the availability and solubility of some plant's nutrients as minerals are insoluble in acidic soil. This will greatly affect the harvest and productivity of the farmers. Therefore, it is recommended to correct the soil's pH and constantly irrigate the farms to help sustain the growth and development of the crops being grown in the said barangay. In the context of the results and analyses of the soil samples gathered in Barangay Lucnab, the researchers organized and conducted training and seminar to the community to correct the pH of the soil by adding lime and applying fertilizer before planting. Appropriate seeds were also distributed to the barangay.
The larval morphology of a new mid-Cretaceous stonefly and its systematic position in Plecoptera
Authors: Chen Zhi-Teng
Published: September 2022

﻿The larval stage is an essential part of the life history of stoneflies and can provide substantial biological and evolutionary information. However, well-preserved fossils of larvae are sparse. Herein, the larval morphology of a new extinct stonefly, Kachinoperla zwickigen. et sp. nov., is described based on its exuvia in mid-Cretaceous Kachin amber from northern Myanmar (98.79±0.62 Ma). The new stonefly also represents a new family, Kachinoperlidaefam. nov. according to its unique characters. Kachinoperlidae can be distinguished from other stonefly families by the following larval characters: predaceous mouthparts, subequal glossae and paraglossae, subequal maxillary and labial palps, reduced apical maxillary palpomere, trapezoidal pronotum, banded and semicircular wing pads, invisible notal contour, absent thoracic gills, shortest first two tarsomeres, and strongly projected abdominal tergum 10. The morphological comparison and phylogenetic analysis suggested the new family as a basal lineage within Systellognatha. Evolutionary implications implied by the larval characters are also discussed.
Elastic plate under low velocity impact: Classical continuum mechanics vs peridynamics analysis
Authors: Altenbach Holm , Larin Oleksiy , Naumenko Konstantin , Sukhanova Olha , Würkner Mathias
Published: September 2022

The aim of this paper is to compare the classical continuum mechanics and the peridynamic models in the structural analysis of a monolithic glass plate subjected to ball drop. Governing equations are recalled in order to highlight the differences and basic features of both approaches. In this study the behavior of glass is assumed to be linear-elastic and damage processes are ignored. The generalized Hooke's law is assumed within the classical theory, while the linear peridynamic solid constitutive model is applied within the peridynamic analysis. Mechanical models for the ball drop simulation are discussed in detail. An emphasis is placed on the discretization including finite element mesh, peridynamic node lattice and time stepping, as well as appropriate constraints and contact conditions in both finite element and non-local peridynamics models. Deflections of the plate after the ball drop are presented as functions of time and the results based on the finite element and peridynamic analysis are compared. Good agreements between the deflection values in selected points of the plate as well as deflection fields at several time points indicate, that the model assumptions for the non-local peridynamic analysis including the horizon size, the short-range force contact settings and the support conditions are well suited. The developed peridynamics models can be applied in the future to analyze damage patterns in glass plates.

Published: September 2022

Nanofluid is an advanced technology to enhance heat transportation. Additionally, the thermal conductivity of nanofluids is high therefore, they are more useful for heat transportation. Evaluation of entropy generation has been a helpful technique for tackling improvements in thermal features because it provides information that cannot be obtained via energy analysis. For thermodynamic irreversibilities, a good approximation is the rate of entropy generation. As a result of a reduction of entropy production, energy transport infrastructure has become more efficient. This study aims to analyse the bioconvective flow of nanofluid flow through a stretching sheet in the occurence of gyrotactic motile microorganisms. A magnetised nanomaterial model with thermophoretic and Brownian diffusion properties is analysed. The impacts of activation energy, temperature dependent and exponential base heat source are investigated in this analysis. The entropy generation of the system is also observed for nanofluid flow. The mathematical model is developed as partial differential equations. The governing equations are reduced to a dimensionless system of ordinary differential equations by applying similarity transformations. The ODEs are tacked numerically with the aid of shooting scheme in commercial software MATLAB. For graphical and numerical results of flow controlling parameters versus subjective fields, the commercial software MATLAB tool bvp4 is used with the shooting scheme. The novelty of this analysis computes numerical computation of bioconvective nanofluid flow with temperature-dependent and exponential base heat source investigated. Furthermore, the consequence of thermal radiation and entropy of the system is considered. The porous medium with activation energy is also taken into consideration. The results show that the velocity field is reduced with increased bioconvection Rayleigh number. The thermal field is increased via an exponential space-based heat source. The concentration is reduced via Lewis number. the microorganisms profile declines for larger bioconvection Lewis number. The Brinkman number Br, magnetic and permeability characteristics all showed a rising trend when plotted against the entropy production rate.

Authors: Wu Qiuhao , Liu Rong
Published: September 2022

In order to study the influence of different modes of online educational videos as teaching materials on learners' learning effect, 60 college students were invited to conduct an experiment. On the experimental materials, traditional and automatic video recording and playing, which account for a large proportion of online education, were selected. The process of watching was recorded by eye tracker experiment, and the learning differences were reflected by subjective evaluation and objective indicators. It was found that compared with the automatic video, the traditional video was more attractive to the subjects, the subjects had more concentration, but the cognitive load was higher, and there was no significant difference between the two groups in terms of performance. In addition, the attention distribution of learners in different modes is mainly illustrated, followed by portrait and subtitles. In the two modes of pictures and text, pictures are the main mode. The above research can provide a scientific basis for video designers to select appropriate modes to highlight key information, help teachers and learners to choose more reasonable learning videos from a large number of educational videos, and help online education providers to improve learners' intuitive experience of videos and enhance their competitiveness.

Authors: Toharudin Uus , Kurniawan Iwan Setia
Published: September 2022

Face-to-face learning cannot be carried out during a pandemic. Changes in student learning styles from face-to-face to online learning suddenly resulted in several new problems, one of which was a decrease in student understanding of lecture material. To overcome this, we are trying to overcome these problems by designing a mini studio that is used to carry out the online learning process. This study aims to determine the effectiveness of the mini studio in improving students' conceptual mastery of the material presented by the lecturer. Using a pre-experimental method, this study involved 132 biology education students at Universitas Pasundan. The results showed an increase in student concept mastery (N-gain = 0.49) in the medium category. Thus, we can conclude that the mini studio is quite effective in increasing students' mastery of concepts. Mini studios can be used as a face-to-face replacement solution for online learning, although it is necessary to increase the learning support devices used in mini studios

Authors: Xie Hua , Xiao Yonghe
Published: September 2022

The current translation training programs at colleges and universities are not fully adequate for students majoring in English, and some students do not perform well in their execution of translation tasks. Translation ability is a frontier topic in the field of translation. A number of studies have provided some new ideas for research on the main goals of translation education and the evaluation of students’ translation abilities, but few has used artificial intelligence to predict students’ translation abilities. This paper analyzes the prediction of the translation ability with respect to complex English sentences. First, based on the principles of accuracy, operability and scientificity, an evaluation indicator system was built to fully reflect the basic characteristics of students’ ability to translate complex English sentences, which is in line with the training needs of translation talents at colleges and universities. Then, based on the characteristics of the logical structures of complex English sentences, a grey Bernoulli prediction model was constructed for the translation ability of complex English sentences. The particle swarm optimization algorithm was selected as the parameter optimization algorithm for the prediction model of translation ability with respect to complex English sentences, with the optimization targets being the Bernoulli parameters and the order of the fractional-order accumulation generation. The experimental results verified the effectiveness of the proposed model.

This paper targets at studying the effectiveness of blended teaching in financial management course based on experiential practice. At first, influencing factors of the effectiveness of blended teaching in the said course were analyzed, and the evaluation flow was given. Then, based on the Least Squares Support Vector Machine (LSSVM), this paper built a prediction model for the evaluation of the effectiveness of blended teaching in financial management course, and constructed a Transfer Learning SVM (TL-SVM) for formulating similar teaching design schemes based on federated learning, and used it to finish the learning of the similar implementation laws of multi-type teaching design schemes and the special implementation features of each single teaching design scheme. The proposed method can well cope with small sample size cases in which the evaluation data of the effectiveness of some teaching design schemes are limited, and the validity of the model was verified via experimental results.
On the Entrepreneurial Intention and Entrepreneurial Behavior Path of College Students Based on the Theory of Planned Behavior
Authors: Zhao Lili
Published: September 2022

It is of practical significance to explore the mechanism of entrepreneurship education on college students’ entrepreneurial intention, as it can provide reference for the innovations in college students’ entrepreneurial ability training mode and the formulation of relevant supporting policies. At present, the relevant research on the influence mechanism of entrepreneurship education on college students’ entrepreneurial intention is not deep enough and lacks relevant empirical analysis, which has led to great differences in the empirical results. Therefore, this paper explores the entrepreneurial intention and behavior path of college students based on the theory of planned behavior. First, an analysis framework of the core elements of entrepreneurial intention was built based on the theory of planned behavior, and the core elements were also analyzed. Then, a measurement model of college students’ entrepreneurial intention was constructed, and the contingent value method was introduced to study college students’ entrepreneurial intention. A schematic diagram of the path relationship of college students’ entrepreneurial behaviors was also given, and the covariance structural equation model for all the specific elements was constructed. The rationality of the model was verified, and how the different core elements of the model are correlated with each other was also explored.
Topic Modeling with Transformers for Sentence-Level Using Coronavirus Corpus
Authors: Mifrah Sara , Benlahmar El Habib
Published: September 2022

A Topic Model is a class of generative probabilistic models which has gained widespread use in computer science in recent years, especially in the field of text mining and information retrieval. Since it was first proposed, it has received a large amount of attention and general interest among scientists in many research areas. It allows us to discover the mix of hidden or "latent" subjects that differs from one document to another in a given corpus. But since topic modeling usually requires the prior definition of some parameters - above all the number of topics k to be discovered -, model evaluation is decisive to identify an "optimal" set of parameters for the specific data.  Latent Dirichlet allocation (LDA) and Bidirectional Encoder Representations from Transformers Topic (BerTopic) are the two most popular topic modeling techniques. LDA uses a probabilistic approach whereas BerTopic uses transformers (BERT embeddings) and class-based TF-IDF to create dense clusters.
Image Encryption Based on Multi-Level Keys on RC5 Algorithm

Published: September 2022

In recent years, the need to develop encryption algorithms has led to an increase in the working and efficiency of algorithms to protect the transmission and reception of information from any security breach. The RC5 type encryption algorithm is the most common and closest to perfection and symmetry algorithms, knowing that it faces many problems in which data collection was limited because it occurs only twice by working on its also, the algorithm is used for only 1 function (XOR) through the encryption process. A research report on digital image development by developing the RC5 algorithm makes that algorithm more secure by adding a new security level (using two keys) and thus increasing the key space. The encryption and decryption process can be done by substituting the XOR operation applied to Sixteen rounds of the algorithm with the new operation (#) based on the use of 2 keys, each of it consisting of 4 states (0,1,2,3) instead of using the traditional key that uses two states (0,1). This development of the RC5 algorithm increases the security and robustness of the hacking methods.
Chinese-Canadian Parents Supporting Dual Online-Offline Learning and Early Biliteracy During COVID-19 School Closures
Authors: Li Guofang , Lin Zhen
Published: September 2022

This chapter investigates how Chinese immigrant families wrestled with a dual-transition from in-person instruction to a virtual environment in both mainstream and heritage language education and how they supported home bi/multi-literacies in English and Chinese heritage language including Mandarin, Cantonese, or other Chinese dialects during the transition. Thematic analyses of 178 parent interviews show that Chinese-immigrant parents have experienced significant changes in their roles and ways in nurturing home early biliteracy development to respond to the schooling transitions from offline to online. Results revealed that the sudden implementation of virtual learning during the COVID-19 school closure has been problematic and challenging for most Chinese-immigrant parents and children.
Yucatec Maya Students' Learning in Times of the COVID-19 Pandemic

Published: September 2022

Although learning conditions during the COVID-19 pandemic were quite difficult, Yucatec Maya students from elementary to university levels did not stop learning, although they did not necessarily follow conventional school ways. Instead, Yucatec Maya families resumed their traditional Indigenous ways of learning. There is no question that during the pandemic these students faced challenges such as a lack of access to technology and equipment for distance education and a lack of motivation, both of which explain the poor performance at school. Nevertheless, this chapter presents evidence of a hidden factor of success, the cultural ways of learning. If these ways are applied properly, they have the potential to contribute significantly to successfully face the challenge of returning to full face-to-face schooling.
Holistic View on Detecting DDoS Attacks Using Machine Learning
Authors: Barros Eduardo , Lobo Victor , Correia Anacleto
Published: September 2022

Distributed denial of service (DDoS) attacks are an enormous threat, mainly because of the extension they can reach, the ease of deployment, the losses that it can cause, and the effort it can take to detect and stop this type of attack. Machine learning techniques have been and are widely used to prevent DDoS attacks. As a matter of fact, many gigantic intrusion detection systems (IDS) have been proudly utilising machine learning techniques to help the conventional signature detection system by adding another layer of “intelligent” thinking. This chapter provides a context of the techniques used for detecting DDoS attacks using machine learning, and in demonstrating why the merge of these concepts have huge potential for the defence of a given system. To that matter, some studies that use machine learning approaches for DDoS detection are analysed. Finally, this chapter provides a high-level view of the types of DDoS attacks that are considered a threat, the machine learning approaches to detect these attacks, and why these approaches are cohesive.
Robotic Hummingbird versus Quadrotor: a Flight Dynamics and Gust Response Comparison
Authors:   Texas A&M University, Coleman David , Benedict Moble ,   Texas A&M University
Published: September 2022

The paper discusses an experimental effort aimed at quantifying and comparing the relative flight dynamics and gust response of a two-winged, biomimetic, hover-capable robotic hummingbird (RH) with wing kinematic modulation methods for flight control, against those of a quadrotor (QR) with the same mass, inertias, and motor and battery mass fractions as the robotic hummingbird. Comparing the linear flight dynamics models, the RH model had 2–3 ×greater translational aerodynamic coefficients along the longitudinal and lateral axes, and rotational aerodynamic coefficients of similar magnitude but opposite sign about these axes. The pitching moment response to longitudinal velocity was similar in the two, while the rolling moment response to lateral velocity was 3.5 × greater in the RH model. Control authority in the longitudinal dynamics was found to be greater in the QR, though this was attributed to mechanism limitations in the RH. The lateral and direction control authority was 1.3 and 4.3 × larger respectively in the RH model. Both vehicles were subjected to a gust in the laboratory. Although the average total movement of the RH was greater than the QR, when the gust speed was non-dimentionalized by the tip speed, the RH had a lesser response. Further, the pitching response was similar between the two, but the rolling response was ≈ 2 × greater in the RH. Finally, the error between the measured and modeled vehicle responses as a function of wind gust velocity was quantified, which generally increased, especially so for speeds > 5 ft/s. The rotational acceleration equations contained the greatest errors. These results suggest that the linear flight dynamics models are not valid for relatively moderate excursions from hovering flight.
God's Machine: The Miracle at Gander
Authors:   U.S. Army (Ret.), Fardink Paul
Published: September 2022

After crossing the North Atlantic Ocean in the early morning hours of September 18, 1946, a Sabena Airlines DC-4 OO-CBG, carrying 37 passengers and seven crew members, crashed in dense fog and drizzle 22 miles short of the Gander, Newfoundland Airport. Considered by many to be the first major civilian airliner crash, it was also the first major U.S. Coast Guard rescue mission with helicopters. Working together, the Coast Guard, the U.S. Army, and Canadian personnel used Sikorsky helicopters and fixed-wing aircraft to successfully complete this heroic rescue of 18 survivors in what the media considered “the Miracle at Gander.” This inter-service and civilian team exhibited unrivaled courage, innovation, and compassion, resulting in a nearly flawless operation. What happened at Gander would also serve as the turning point for future Coast Guard rescue mission use of the helicopter, which many, then and since, have considered to be “God’s machine.”
