Published: September 2020

This study aimed to develop a reliable and valid instrument to measure secondary school students’ attitude towards robotic coding and the results of the analyses regarding the Robotic Coding Attitude Scale (RCAS) developed for this purpose were reported in the current study. To test the construct validity of the first version of the RCAS consisting of 29 items, Exploratory Factor Analysis (EFA) was performed on the data from 196 seventh-grade secondary school students (who had received robotic coding education already) enrolled in the public schools in a city in the northeastern Turkey. As a result of the EFA, the 22-item five-factor model was extracted. Then, the 22-item five-factor model obtained from EFA was cross-validated using Confirmatory Factor Analysis (CFA) and the results indicated acceptable model fits where χ2/(df = 197) = 1.827, NFI = .825, CFI = .911, RMSEA = .065. Cronbach’s Alpha coefficient which was calculated to show whether the RCAS is a reliable scale was found to be .91. In sum, the results indicated that RCAS can be used as a reliable and valid instrument to measure secondary school students’ attitude towards robotic coding.

Published: September 2020

Engineering identity plays a vital role in the persistence of engineering students, yet limited research exists on how particular pedagogical approaches influence engineering identity at the college level. This qualitative case study explored how undergraduate student perceptions of design thinking pedagogy influence computer, electrical, and software engineering identity. The study found that design thinking pedagogy reinforces the recognition of an engineering identity, particularly for those from historically marginalized groups (i.e., women, people of color). Intentional implementation, including organization and framing of design thinking pedagogy, was an essential foundation for fostering student interest in the course and connecting to their role as engineers. This study suggests that design thinking is a fruitful area to explore to create more inclusive engineering environments. This study’s findings will assist educational stakeholders in understanding the design thinking pedagogy and engineering identity experiences of CES undergraduate engineering majors. Findings may encourage institutions to view the engineering curriculum in terms of identity development and understand how intersectional identities influence the ways students, particularly those from marginalized backgrounds, experience the environment.

Increasing demands coupled with environmental effects of conventional fuels have over time been a source of great concern to seek cost-efficient and environmentally friendly fuels. This work is therefore, to determine the fuel properties of biodiesel from neem (Azadirachta indica) and jatropha (Jatropha curcas) seed oils using whole-cell biocatalyst. Seeds of both neem and jatropha wyere extracted from kernels using a two-staged mechanical process. Whole-cell biocatalyst-mediated trans-esterification of oils into fatty acids methyl esters (FAME) were achieved by the used of isolated strains of Rhizopus orizae. After pretreatment, the percentage yield of oils from seed kernels of neem and jatropha were found to be 29.49±0.12% and 34.18±0.16% respectively while biodiesel yields from oils of neem and jatropha were 91.20±0.02% and 89.90±0.08%. The neem and jatropha based biodiesels had specific gravities of 0.879±0.002 and 0.877±0.001, flash points (173±1.11 and 135±1.14oC); fire points (205±0.11 and (193±0.01oC) water and sediments (0.04±0.001 and 0.02±0.001%); kinematic viscosity (2.30±03 and 2.10±0.06 cst @ 37.8oC); API gravity (29.48±0.37) and (29.85±1.9); free fatty acids (0.65±0.03 and 0.38±0.04% KOH); ash contents (0.03±0.001 and 0.01±0.001%); iodine number (79.6±0.1 and 20 ±0.2 mg I2/g); saponification value (186.38 ± 0.17) and (191.75 ± 0.11mg (KOH)/g); and peroxide value (7.91±0.09 and 2.50 ± 0.03mg/kg), respectively. Fuel properties of biodiesel compared favorably with American standards for testing materials (ASTM) established limits for biodiesel fuels which showed great potentials in the use of non-food oils coupled with green chemistry in the field of biodiesel research and development.

Published: September 2020

Environmental concerns associated with petroleum resources have propelled the development of sustainable and renewable alternatives to petroleum based products. Vegetable oil is one amongst the foremost abundant bio-based feedstocks. The interest in using vegetable oils and low molecular weight alcohols by direct transesterification have shown great potential as alternatives to petroleum-based diesel, and the production of bio-based diesel continues to increase. Utilization of multi-response surface methodology (MRS) for the most effective combination effect or response from the uses of input to output variables to optimize the yield and higher heating values (HHV) of biodiesels was investigated. In this work, utilizing variety of non-edible vegetable oils like castor (Ricinus communis L), jatropha (Jatropha curcas), and neem (Azadirachta indica) seeds and several process variables or inputs, including mixing time, mixing speed, process temperature and catalyst dosage to formulate high quality renewable fuels were further explored. The outputs were yield, viscosity, higher heating value, density and turbidity. The proposed optimization scenarios for biodiesel using the statistical (MRS) models was aimed to optimize the processes to achieved high conversion and higher heating values, while reducing the reaction time, turbidity, density, and viscosity in the samples. The results showed catalyst dosage as the most important variable for all the three samples. For maximum yield of 100%, the molar ratio of 6.25, catalyst of 0.75 wt.%, reaction speed of 499.99 rpm, reaction time of 19.88 min and temperature of 24.50 oC were found as optimal conditions; while the molar ratio of 5.60, catalyst of 1.01 wt.%, the reaction speed of 499.5 rpm, reaction time of 20.00 min and temperature of 35.50 oC were optimal conditions for maximum biodiesel yield.
PROJECT-BASED LEARNING AS AN APPROACH TO DEVELOP CRITICAL THINKING SKILLS: A LITERATURE REVIEW
Authors: Junisbayeva Symbat
Published: September 2020

Project-Based Learning is a learner-centered approach, which is known as one of the ways that facilitates the development of professional competencies and promotes learners’ critical thinking skills. This paper provides a selective review of the literature and the analysis of the studies on Project-Based Learning (PBL) in the field of foreign language education and critical thinking skills including the main concepts, key components and a learning process within PBL. PBL has a strong theoretical support from the foreign literature, and most of the researchers understood and implemented it as an approach to foster critical thinking skills in the reviewed studies; however, not all of them complied with its essential elements proposed as “Gold Standard of PBL”. Particularly, the analysis of the selected studies in PBL sphere revealed that most of the researchers did not take into consideration the requirements of the last and main stage of the PBL as “Public product”, that demands the projects to be presented in front of the alternative audience. Even though the final products were designed within these projects, they were not performed out of the classroom, which in its turn is opposite to the policy of rigorous “Project-Based Learning”. Key words: PBL, critical thinking skills, foreign language education

The purpose of the article: to provide a method that would make it easier for students to understand and accept the new topics at school and to remember the learned materials for a long time.Increasing the interest and activity of schoolchildren is an important part of the learning process. Motivating students is one of the biggest challenges for teachers. It is quite possible that the use of traditional teaching methods alone will cause indifference in students. Therefore, it is better to use active learning methods so that the lesson is not boring. In this regard, the use of game-based learning technology can increase the motivation of students to learn.Based on the research materials, it can be concluded that the game-based learning method facilitates students' learning and motivates students, allows them to work with classmates, i.e. increases the ability to work in groups, helps to overcome indifference to mathematics, creates a fun learning environment.
The role of repetition in learning math
Authors: Yessenbolkyzy Akerke Yessenbolkyzy , Yessirkepova Ardak
Published: September 2020

Mathematics is one of the most important aspects of school education. School mathematics is a meaningful, fascinating and accessible field of activity, giving the student rich food for the mind, connecting him with universal human culture, forming the most important personality traits.In learning mathematics, practice makes perfect. In the process of teaching math, the repetition of the studied material is given an important place. Properly organized repetition is one of the factors contributing to the intellectual development of each student, their achievement of deep and lasting knowledge. The need to repeat the previously studied material is caused by the very structure of the curriculum of mathematics. For example, students go through the curriculum topic: “Quadrangles” in 8th grade, but use it in grades 10-11 when studying the topics: “Surface of bodies of revolution”, “Surface area”, “Volume of bodies”, etc.To teach mathematics without repeating the material previously passed on every lesson every day, this means transmitting, retelling to students a certain amount of different laws, theorems, formulas, etc., completely not caring about how firmly and consciously this material was mastered by our pets; it means not giving children deep and lasting knowledge. Researches showed us that repetition is the  main  instrument  of  the  study.  Results  of  the  analysis  revealed  that  students  exposed  to  repetition  with variation approach had significantly higher achievement, conceptual understanding and improved retention.

Published: September 2020

Confidential data security is associated with the cryptographic primitives, asymmetric encryption, elliptic curve cryptography, homomorphic encryption, cryptographic pseudorandom sequence generators based on an elliptic curve, etc. For their efficient implementation is often used Residue Number System that allows executing additions and multiplications on parallel computing channels without bit carrying between channels. A critical operation in Residue Number System implementations of asymmetric cryptosystems is base extension. It refers to the computing a residue in the extended moduli without the application of the traditional Chinese Remainder Theorem algorithm. In this work, we propose a new way to perform base extensions using a Neural Network of a final ring. We show that it reduces 11.7% of the computational cost, compared with state-of-the-art approaches.
Application of software tools for symbolic description and modeling of mechanical systems
Authors: Banshchikov A. , Vetrov A.
Published: September 2020

The paper presents two software tools (graphical editor and software package). The editor is designed for the formation of a symbolic description of a mechanical system using the Lagrange formalism. A system of the absolutely rigid bodies connected by joints is considered as a mechanical system. The editor is a user interface by which one sets the structure of the interconnection of bodies (system configuration) as well as the geometric and
kinematic characteristics for each body of the system. The created structure and the entered data are automatically presented in the form of a text file, which is used as an input file for the software package for modeling mechanical systems in a symbolic form with a computer. The use of these software tools is shown in detail in the example of the analysis of the dynamics of a satellite with a gravitational stabilizer in a circular orbit. For this system, the kinetic energy and force function of an approximate Newtonian gravitational field were obtained, nonlinear and linearized equations of motion were constructed, and the question of the stability of the relative equilibrium position was considered.
Asynchronous-streamed model for describing dynamically changing parallelism
Authors: Legalov A.I. , Romanova D.S.
Published: September 2020

The article presents the concept of an asynchronous-streamed model, which is an extension of the functional data-flow model of parallel computing. We suppose that the model will be used to describe dynamically changing parallelism. This model is based on the concept of asynchronous lists, which allow considering their parallelism as an independent way of describing the parallelism of the program. The specifics of asynchronous lists are represented. Using the examples, we show how to use this model to get temporary estimates of parallelism at different conditions of solving the problem. These estimates depends on correlation between data speed getting and computation time those data in parallel devices. Also, we demonstrate how two connected asynchronous-streamed functions can form pipeline automatically. As a result, we show out that on this model it is possible to obtain temporary estimates of the calculations performed and estimations which demonstrate the levels of parallelism.

Authors: Oparin G.A. , Bogdanova V.G. , Pashinin A.A.
Published: September 2020

We offer a specialized toolkit for automating both knowledge management when creating an applied microservices package and data accumulating during its application for scientific computations in a hybrid computing environment. The decentralized solving of the declaratively formulated problem is carried out by an active agent group. This group is self-organized by logical inference on the distributed knowledge base of a subject domain. The developed toolkit automates the creating and updating of the local knowledge base of the manager-agent of applied microservices package, as well as the local knowledge bases of distributed computational agents. Local knowledge bases are formed using a description of the interface of computational microservices managed by these agents. Microservice ensembles, corresponding to the active group, are stored in the knowledge base of the manager-agent. The developed toolkit uses this information for testing microservice in the case of its update. In hybrid computing, this toolkit provides synchronizing, archiving, and saving of calculated data. Hybrid infrastructure combines the reliability and availability of using on-premises computers with scaling to the cloud when peak loads occur. The conducted experiments confirmed the effectiveness of the presented approach for solving practically significant scientific problems.

Islamic education is expected to be able to shape students who are required to be able to apply religious spiritual values and ethical, but what has not yet achieved what is targeted. As a solution there needs to be an update in the concept of education. The writing of this paper uses library research methods, namely finding and analyzing various information related to the discussion through books, journals and texts related to the discussion. It was found that the thought of al-Zarnuji's education was relevant to the modern era, namely: 1) Educational objectives, relevant from the existence of conformity with national education goals in the 2003 National Education System Law on educational goals, which between the two emphasized morals. 2) Educators, can be seen from the teacher's personal competence, which is a strong personality ability, noble, wise, and authoritative as well as an example for students. 3) students, it is relevant to be seen from the conformity with Law on National Education number 23 of 2003 Chapter V article 12 that students have an obligation to maintain the norms of education. 4) curriculum, can be seen from the basic foundation of Islamic Education curriculum including the basis of religion, and there is also a psychological basis. 5) Education Method, it can be seen that in the present era the memorization method and the discussion method are still used while still based on needs.

River ecosystems are exposed to various stressors, surface sediments as a constitutive part thereof are an essential feature for the evaluation of aquatic ecosystems status. This paper aims to assess the surface sediment quality in the lower section of the Danube River, in terms of hazardous substances content (As, Cd, Cr, Cu, Pb, Hg, Zn, Ni, PAH and PCB). For this purpose, 10 monitoring sites have been assigned for a period of September 2011-August 2017, where construction works were carried out with the purpose of improving the navigation conditions, which also involved sediment dredging. A total approximately of 1200 surface sediment samples have been collected from the Danube River (km 375-km 175), from the left and right banks, monthly during the construction period (2011-2015) and quarterly in the post-construction period (2015-2017). This study gives a description and more detailed evaluation of the integrated assessment of hazardous substances which was carried out in the surface sediments from the Lower Danube River using statistical analysis. The surface sediment quality evaluation was based on comparison of the obtained values with the chemical quality standards set out in the Romanian legislation (M.O. 161/2006). For a more in-depth assessment of the relationship between hazardous substances and for the identification of potential anthropogenic and natural sources, Principal Component Analysis (PCA) and Cluster Analysis (CA) have been used.

This paper presents the results obtained during the electrogeneration of active chlorine species. Active chlorine species were generated through the electrolysis of sodium chloride solutions in an undivided cell, employing two platinised platinum electrodes and a polarity reversal procedure. The electrolytic process was conducted at four current densities (0.05, 0.10, 0.30 and 0.50 A/cm2) and three concentrations (0.1, 0.5 and1 mole/L) the polarity reversal period being of 5 min. The brine flow rate was kept constant, namely 1.68 L/h. The results showed a maximum active chlorine concentrations for an initial brine concentration of 0.5 mole/L. The overall concentration of dissolved chlorine in water was quantified as active chlorine, defined as the sum of the three possible species (Cl2, HClO and ClO-).

In recent years, much research has been done on nonlinear vibrations, and analytical and numerical methods have been used to solve complex nonlinear equations. The behavior of nonlinear oscillating equations is discussed until the second order is approximated. Harmonic balance method, which itself has limitations in application. This method continues to be able to study a wider range of nonlinear differential equations. In general, nonlinear vibration problems are of great importance in physics, mechanical structures, and other engineering research. First, the equation of nonlinear vibrations governing the mass of the particle mass connect to the drawn cable is calculated and then the Newton Harmonic Balance Method is used to study the nonlinear vibrations of the set and obtain the answer and its frequency. The method (NHBM) is done with Maple software and a comparison between the results of this method with the solution methods used by other researchers is shown to be a good match.

Published: September 2020

A general procedure for heat exchanger design has been presented in the Heat Exchanger Design Handbook (HEDH) [1], but no precise criterion for determining baffle cut nor baffle  spacing has been offered, and the emphasis is only on heat exchanger’s permissible range of application. In this paper, an optimization program has been used to calculate pressure drop, fluid velocity, heat power, overall heat transfer coefficient and middle temperature difference for various baffle cut and baffle spacing for the same type of heat exchanger, using the procedure in HEDH. This could be considered as complementary to the HEDH recommendations and can be used by designers and, generally, engineers for determining the right baffle cut and baffle spacing for their specific cases.

Authors: Alzarzouri Fadi , Fawaz Deri
Published: September 2020

Poly lactic acid (PLA) and High density polyethylene (HDPE) have been blended   in a Brabender plastograph in the molten state. The melt die swell of the blends has been studied by using a capillary rheometer. Effects of the capillary dimensions, shear stress, shear rate, temperature and blending ratio on die swell of PLA/HDPE blend melts were investigated.    The results showed that die swell ratio decreased with increasing of capillary length and temperature while it increased with increasing of shear stress, shear rate and capillary diameter. It was also found that the plots of die swell versus blending ratio go through a maximum for blending ratio PLA/HDPE (60/40).

The utilisation of pozzolanic materials as the replacement to conventional cement material have the potentiality to mitigate the pollution caused by the émission of carbon based green house gases which are a main source for global warming problem. For every production of 1 ton of cement it was approximated that the emission of carbon based green house gases are about 1 ton. Keeping this in view, a new material called Geopolymer which was first coined by Davidovits has gained a lot of interest by the researchers. In this study, different molarity variations of NaOH in the order of 4M, 6M, 8M, 10M, 12M and 14M and also the blending of  mineral admixtures like Fly Ash and Ground Granulated Blast Furnace Slag with percentages (50%+50%) and the mechanical properties of normal M30 and high strength grade M70 binary blended Geopolymer concrete were studied after 28 days of ambient curing and were reported. The test results revealed that the effect of molar concentration of NaOH at 12 M is effective and the optimum replacement of mineral composition of source materials is (50%+50%) fly ash and ground granulated blast furnace slag.
