An overview of path planning technologies for unmanned aerial vehicles
Authors: Bal Mert
Published: July 2022

Unmanned aerial vehicles, due to their superior maneuverability and reduced costs can easily perform tasks that are too difficult and complex to be performed with manned aircraft, under all conditions. In order to cope with various obstacles and operate in complex and unstable environmental conditions, the unmanned aerial vehicles must first plan its path. One of the most important problems to investigated in order to find an optimal path between the starting point and the target point of the unmanned aerial vehicles is path planning and choosing the appropriate algorithm. These algorithms find the optimal and shortest path, and also provide a collision-free environment for unmanned aerial vehicles. It is important to have path planning algorithms to calculate a safe path to the final destination in the shortest possible time. However, algorithms are not guaranteed to provide full performance in each path planning situation. Also, each algorithm has some specifications, these specifications make it possible to make them suitable in complex situations. Although there are many studies in path planning literature, this subject is still an active research area considering the high maneuverability of unmanned aerial vehicles. In this study, the most used methods of graph search, sampling-based algorithms and computational intelligence-based algorithms, which have become one of the important technologies for unmanned aerial vehicles and have been the subject of extensive research, are examined and their pros and cons are emphasized. In addition, studies conducted in the field of unmanned aerial vehicles with these algorithms are also briefly mentioned.

Published: July 2022

This study aims to generate, independently from the electric network, one
part of the electrical energy required in the existing electric vehicles,
utilizing the wind en?ergy raised by on-the-go vehicles and thus enhancing
the distance covered at one single charge. Regarding that aim, the effect of
vehicle type wind turbine, which was designed so as not to cause an increase
in the vehicle projection area, on the aerodynamic performance and energy
efficiency of the vehicle was analyzed numer?ically. Using the shear stress
transport k-? turbulence model, CFD simulations were conducted to determine
the drag coefficients, pressure contours and velocity vectors of the
designed basic vehicle model (M0) and its two different modified versions
(M1, M2). The ANSYS-FLUENT software was used for numerical simulations. In
the data obtained from the simulation results, the drag coefficient,
compared to the M0 model, was determined to undergo an increase by 8.49% and
4.05%, respectively for M1 and M2 models. The total energy loss of the M2
model increased by 2.47% compared to the M0 model. The net energy gain
produced through the wind turbine in the M2 model constituted approximately
5.13% of the total lost energy of the M0 model vehicle. In this context, the
energy gain yielded from the wind turbine placed on the vehicle was observed
to be higher than the wind turbine-caused energy loss. Thus, it was
determined that the study positively contributed to the prolongation of the
vehicle driving distance on a single charge.
Investigation of cutting parameters in milling of DIN 1.2379 and Sleipner materials
Authors: Girit Oguz
Published: July 2022

In today?s machining conditions, the goal is to produce the most suitable quality with the lowest cost. In order to minimize the problems of mouth spillage, especially those used in cutting molds, we have studied Sleipner material as an alternative material and examined the machinability parameters between DIN 1.2379 material used in the application. In this study, with the aid of a force gauge, the forces generated on the material during machining, the surface roughness values after machining with the help of surface roughness device and the temperature values of the materials during machining were measured with the temperature gauge. A total of twelve experiments were carried out for each material at three different chip depths at constant cutting speed and four different progressions for each chip depth. These experiments have been understood from the results obtained from the data that Sleipner material has shown a more stable structure and better results than DIN 1.2379. Thus, the negative manufacturing conditions that may occur during mold production and during mold operation are minimized. In this case, it is necessary to take into consideration the number of the parks produced in the mold and the frequency of mold usage in the material selection of the cutting steel of the cutting molds.

Examining Modern Mechanics as a Three-System Classical Mechanics-Based Theory of Moving Systems
Authors: SB Bryant
Published: July 2022

Supported through a century of investigation, experimental support, and observational evidence, relativity is accepted as being conceptually sound, mathematically correct, and theoretically valid. Because it is believed to be the only theory that quantitatively explains certain experiments and yields 2 E mc = , there is widespread support that any improvement will take the form of an enhancement to, rather than a replacement of the theory. Despite this degree of support, the seminal derivation of special relativity theory found in Section 3 of On the Electrodynamics of Moving Bodies contains a mathematical contradiction that must be remediated. Specifically, the τ and ξ equations are expressed in terms of x, y, and t, where Einstein derives ξ as ξ τ = c , which is immediately followed by his stating the ξ and τ equations as: 2 vx t c τ β  = −     and ξ β = − (x vt ) , where 2 2 1 1 v c β = − . The contradiction occurs because the mathematical equality of ξ τ = c is not maintained when both equations are evaluated using most combinations of x, y, and t. As a concrete example of the contradiction, when x=1, v=0, and t=0, we find thatξ = 1 and τ = 0 , such that ξ τ ≠ c . Here, we introduce Modern Mechanics, a three–system, classical mechanics–based model of moving systems, that does not contain the contradiction. While Modern Mechanics shares a common mathematical kernel with relativity, it uses different equations that can be viewed as an enhancement, or improvement, to the special relativity mathematics. Experimentally, Modern Mechanics yields 2 E mc = and produces a quantitatively better result for the Michelson-Morley experiment. Conceptually, Modern Mechanics differs from relativity because it removes the contradiction, concepts and restrictions associated with relativity; integrates kinematics and electromagnetism while retaining the translation equation for moving systems; and offers novel insights into Einstein’s two–system relativity theory derivation (including discussing where and how the inequality is introduced).

Published: July 2022

Semantic is associated with the relationship between symbol, reference, and the problem’s context involved in the problem-solving process which also involves reasoning and decision-making. Hence, this study describes the characteristics of students’ semantic reasoning to solve the double discounts problem. 51 high school students in Sidoarjo participated in this qualitative study. The data were collected through 15-20 minutes problem-solving tests. The students' answers were grouped into correct and wrong answers. The correct answers were then regrouped once more based on the strategies used by the students to answer the test and to identify their semantic reasoning characteristics. The data were analyzed by reducing, classifying the think-aloud and observing. Then the similarity of characteristics of students' semantic reasoning when solving the double discount problem was identified. To test the accuracy of the data, triangulation method was used. This semantic reasoning was identified by  (1) giving the problem situation, (2) stating the keywords and their meaning, (3) stating the relationship, (4) transforming it into a mathematics statement, (5) calculating based on their strategies, (6) decision making, and (7) completing the answer interpretation. This study contributes to developing basic knowledge in interpreting each process of solving ill-structured problems until finding a solution.

Published: July 2022

This study sought to investigate in-service mathematics teachers’ knowledge of differentiated instruction in junior high schools in Tano South Municipality of Ghana. The study adopted an explanatory sequential mixed method design. We employed a sample of 50 JHS mathematics teachers comprised 41 general in-service teachers and 9 special in-service teachersin the quantitative study through proportionate stratified sampling technique. In the qualitative phase, 6 JHS mathematics teachers comprising 4 general in-service teachers and 2 special in-service teachers were purposively selected and interviewed. In line with the design adopted, the quantitative data obtained through questionnaire was first collected and analysed. This was followed by the qualitative data obtained through semi-structured interviews. The quantitative data were analysed using both descriptive statistical tools (such as frequency counts, percentages, mean, standard deviation and average per item rating), and inferential statistical tool (independent samples t-test). Qualitative data used inductive content analysis. Among the findings, we found no statistically significant difference in the knowledge scores on differentiated instruction for general in-service teachers and special in-service teachers (t = -0.80, df = 48, p 0.05). We therefore recommend teacher education institutions to review their mathematics curriculum to reflect the use of differentiated instructional approaches among mathematics teachers.

Published: July 2022

Background: Attempts at curbing the spread of SARSCoV-2 have resulted in formulation and adoption of COVID-19 protocols in different countries. To further prevent contracting the virus, many developed countries are administering COVID-19 vaccines to their citizens and residents while the developing countries are not left out. The Nigerian government began administering COVID-19 vaccines on March 9, 2021. This study therefore analysed the acceptance of COVID-19 vaccines across different states in Nigeria.Methods: The study utilised secondary data of COVID-19 vaccination in Nigeria. The dataset was obtained from OpenAFRICA, which was first created on September 1, 2021 and last updated in September 29, 2021. The data were statistically analysed and then mapped using the Geographic Information System.Results: The findings showed a very low level of acceptance of the full doses of COVID-19 vaccines vis-a-vis the population of each of the thirty-six (36) Nigerian States.Conclusion: We therefore conclude that the population responses to receiving COVID-19 vaccines is very low in Nigeria, which signals a high level of health risk and vulnerability to the virus.

Published: July 2022

Istraživanje je usmjereno na samoprocjenu kvalitete života i rada medicinskih sestara u Domu zdravlja Zagreb – Centar te utvrđivanje razlika u kvaliteti života i rada medicinskih sestara/tehničara tijekom aktualne pandemije bolesti COVID-19 u odnosu na prethodno razdoblje. Istraživanje je provedeno na uzorku od 113 medicinskih sestara i tehničara koji rade u Domu zdravlja Zagreb – Centar. Istraživanje je provedeno primjenom triju upitnika: upitnikom za određivanje indeksa radne sposobnosti (engl. Work Ability Index Questionnaire, WAI), upitnikom o kvaliteti života Svjetske zdravstveneorganizacije (engl. World Health Organization Quality of Life – Brief Version Questionnaire, WHOQOL-BREF) te upitnikom o radnoj sposobnosti i kvaliteti života tijekom pandemije bolesti COVID-19. Rezultati su pokazali da većina medicinskih sestara/tehničara (84 %) živi ispunjenim privatnim životom, dok manje od polovice ispitanika (46 %) živi ispunjenim profesionalnim životom. Više od 80 % medicinskih sestara/tehničara navodi da su u većini slučajeva i prilično često aktivni i u pokretu, a nijedan ispitanik nije potpuno neaktivan. Nedostatan broj radnika, prijetnje sudskom tužbom i parničenjem predstavljaju najveći čimbenik stresa medicinskim sestrama/ tehničarima na radnom mjestu. U cjelini, usporedba kvalitete života ispitanika za vrijeme pandemije pokazuje odstupanja u povećanom doživljaju stresa i osjećaju zdravstvene ugroženosti, no nema promjena u obavljanju fizičke aktivnosti i međuljudskim odnosima.

Uma análise diplomático-paleográfica no Brasil setecentista: quem escreveu os pasquins sediciosos da Conjuração Baiana?
Authors: Lose Alícia Duhá , Santos Libania Da Silva
Published: July 2022

Este trabalho se constitui em uma análise dos manuscritos produzidos e acumulados no contexto da Revolta dos Búzios, importante episódio da História do Brasil Colônia, custodiados pelo Arquivo Público do Estado da Bahia. A partir da afixação, em locais públicos da cidade de Salvador em 12 de agosto de 1798, de papeis que conclamavam a população bahinense para um levante que traria uma República caracterizada com os ideais franceses de liberdade, igualdade e fraternidade, são instauradas devassas para a identificação e punição dos autores dos ditos documentos sediciosos e demais envolvidos com o projeto de libertação do jugo português. Com um olhar interdisciplinar moldado pelos conhecimentos em filologia, paleografia, diplomática e história, procedemos a um detalhado exame destes manuscritos com enfoque no processo de avaliação de autos de exame, e combinação das Letras dos pesquins, sendo possível averiguar se os manuscritos em questão são de fato originais e se as conclusões dos “letrados”, que subsidiaram a condenação à pena capital a um dos réus por conta da autoria dos boletins manuscritos, foi ou não justa.
Entre caudas e prolongamentos: os desafios da leitura paleográfica
Authors: Módolo Marcelo , Negro Helena De Oliveira Belleza
Published: July 2022

O presente trabalho analisará documento processual eclesiástico que data do século XVIII, elaborado em São Paulo. A identificação dos punhos e a análise da variabilidade da escrita serão os pontos centrais do estudo, que tem como objetivo o estabelecimento dos grafemas e identificação das similaridades entre as letras de mesmos punhos. A metodologia utilizada para analisar a escrita documental foi o estudo comparativo entre as aplicações realizadas pelos diferentes punhos, bem como a incidência do uso de sinais abreviativos, que podem apresentar uma caracterização dos escribas responsáveis por seu uso, já que nem todos faziam utilização das abreviaturas. Por fim, a investigação elucida como o uso da paleografia é importante para os estudos linguísticos e filológicos, uma vez que sem a leitura paleográfica não se pode identificar as minúcias textuais.
The Effectiveness Of The Application Of The Last Resort Principle On Child Residivists In The Child Criminal Justice System

Published: July 2022

Improper criminal imposition can ignore child protection arrangements, because child punishment should be the last resort or the last resort principle and imposed only for a short time. The method used in this research is empirical legal research. Empirical legal research is legal research conducted by examining primary data, namely data obtained directly from the community. As for the results of the Guidance Program for Correctional Students at the Class II Maros Special Child Guidance Institute, there are still some shortcomings such as the absence of a legal awareness program and the provision of formal education which indirectly affects the non-fulfillment of the rights of correctional students, especially because there are still adult prisoners who should be separated from children. The actual role of the officers of the Child Special Guidance Institution in its implementation is still not optimal due to the lack of quality and human resources, and there is no special coach for children.

MEASURE OF SPREAD: TYPE OF ERRORS THAT STUDENTS MADE IN PROBLEM-SOLVING
Authors:   Universitas Negeri Makassar, Zil Ikram Fadhil
Published: July 2022

The measure of spread is one of the concepts in Statistics that students find complicated. We have to use a specific formula or concept for a specific situation or contextual problem. As a result, people or students sometimes made mistakes or errors in solving statistics problems. Therefore, research to investigate errors made in solving problems involving a measure of spread is necessary. This study aims to describe students' errors in solving problems related to the measure of dispersion. Researchers used a qualitative descriptive approach. We administered the test during the even semester from January to June in the year 2021. The participants were 80 undergraduate students who have completed or taken statistics courses. This test consists of 2 questions that are related to each other. Researchers used the three main steps to analyze the data which consist of data condensation, data display, and verifying and drawing the conclusion. We obtained the data related to students' errors from their test results. The results showed that more than 50% of students still make mistakes on every problem. The mistakes made by participants consisted of the use of formulas, miscalculations, the use of known data, the use of concepts, not giving conclusions, and inconsistencies.

This study aims to determine the influence of the cruickshank model on mathematics learning outcomes in grade VIII students of SMP Negeri 1 Marioriawa, Soppeng Regency. This research is an experimental study that uses a quasi-experimental design research design. The study population was all grade VIII students of SMPN 1 Marioriawa, Soppeng Regency for the 2020–2021 school year, a total of 104 people divided into 5 classes. Samples were taken with a simple random sampling technique that was selected into an experimental class taught using the cruickshank model and a control class taught without using the cruickshank model. The research model used is a pretest-posttest control group design. Data collection techniques were carried out using multiple-choice test instruments in the form of 20 numbers. Data analysis techniques are performed with descriptive statistical analysis and inferential statistical analysis. The analysis of inferential data for the instrument was conducted in the form of a test using the Mann-Whitney u-test using SPSS with a significant level of 5%, α = 0.05 previously set. The results of the study showed that there was a significant influence of the cruickshank model on mathematics learning outcomes in grade VIII students of SMPN 1 Marioriawa, Soppeng Regency, where learning outcomes in students taught with the cruickshank model were higher than in students who were taught without applying the cruickshank model.

The purpose of this study was to determine how big the contribution of mathematical disposition and metacognition to students' mathematics learning outcomes is. The approach used is quantitative. The research type is ex-post-facto. The populations were all eighth-grade students of SMP Negeri 3 Sungguminasa, Gowa Regency with a total sample of 105 students who were taken using the cluster random sampling technique. Collecting data using a questionnaire instrument and a test of mathematics learning outcomes. The data analysis technique used is descriptive analysis and inferential analysis (linear regression analysis). The conclusion of this research is: (1) the contribution of mathematical disposition of 0.4% to learning outcomes while the other 99.6% were other variables not examined; (2) the contribution of 4.6% metacognition on learning outcomes while the other 95.4% are other variables that are not studied at; (3) the contribution of mathematical disposition and metacognition simultaneously was 5.1% on students' mathematics learning outcomes while the other 94.9% were other variables not examined; (4) mathematical disposition has a positive influence on the mathematics learning outcomes of class VIII students; (5) metacognition has a positive effect on students' mathematics learning outcomes which can be seen in the equation Y=0.071X1+0.216X2+0.97 which illustrates that an increase in one unit of Y will increase X1 by 0.071 and X2 by 0.216.
A Novel Approach to Type-Reduction and Design of Interval Type-2 Fuzzy Logic Systems

Published: July 2022

Fuzzy logic systems, unlike black-box models, are known as transparent artificial intelligence systems that have explainable rules of reasoning. Type 2 fuzzy systems extend the field of application to tasks that require the introduction of uncertainty in the rules, e.g. for handling corrupted data. Most practical implementations use interval type-2 sets and process interval membership grades. The key role in the design of type-2 interval fuzzy logic systems is played by the type-2 inference defuzzification method. In type-2 systems this generally takes place in two steps: type-reduction first, then standard defuzzification. The only precise type-reduction method is the iterative method known as Karnik-Mendel (KM) algorithm with its enhancement modifications. The known non-iterative methods deliver only an approximation of the boundaries of a type-reduced set and, in special cases, they diminish the profits that result from the use of type-2 fuzzy logic systems. In this paper, we propose a novel type-reduction method based on a smooth approximation of maximum/minimum, and we call this method a smooth type-reduction. Replacing the iterative KM algorithm by the smooth type-reduction, we obtain a structure of an adaptive interval type-2 fuzzy logic which is non-iterative and as close to an approximation of the KM algorithm as we like.
