Strategy for Implementing Elearning to Achieve Outcome-Based Education
Authors: Et. al. Muhammad Rozahi Istambul,
Published: April 2021

Currently, the use of eLearning in education is increasingly playing a role, especially in universities. Thus, it is very important to innovate in designing optimal learning strategies. The meaning of optimization does not only mean that related activities: materials, forums, discussions, assignments, and quizzes that have been delivered by lecturers to students, but outcome-based education (OBE) from the courses delivered can be optimal effectively and efficiently in the learning process. [1]-[2]. As is known in general, universities in Indonesia will conduct lectures for 16 meetings following the implementation of mid-term and end-semester exams, which in the end all activities that have a component of their value will be recapitulated into the final score. This first method cannot be said that students have achieved optimal OBE [3]-[4] because students only carry out the obligations of lecturer assignments every week. In this case, students who have fulfilled their obligations cannot pass the material that has been delivered by the lecturer (pause) to gain additional knowledge, because students do not have the challenge to continue to the next material. This condition occurs because the lecturer next week again provides the material with obligations that must be done by students, and usually the latest topics do not continue the material on the previous topic. Another learning strategy is that the learning process does not have to refer to the completion of the 4-month meeting, but is given the opportunity for students to organize their own learning so that they can immediately reach the intended OBE. Of course, starting with the provision of several materials and targets that must be achieved so that students can creatively manage their own time by solving the problem. The weekly topic contains condensation of several topics that have been designed according to OBE. Furthermore, this study will compare the extent to which OBE optimization can occur in students between the two learning process models carried out by eLearning [5].

Authors: Et. al. Salah Eddine Rhaili
Published: April 2021

Variable structure strategies have shown an efficient performance in controlling nonlinear electrical power systems by reason of its strength to handle perfectly the unmodeled system dynamics. In this study, with the exponent reaching law, a robust enhancement method of sliding mode controller (SMC) based on a nonlinear fractional order sliding surface that consists of both fractional differentiation and integration is proposed and applied to control a high-power multiphase permanent magnet synchronous generator based direct-driven Wind Energy Conversion System (WECS), in order to improve the energy efficiency and reduce the produced chattering phenomenon of conventional SMC . Moreover, a new smooth and derivable nonlinear switching control function is applied to replace the traditional non-derivable nonlinear control law, to improve dynamic performance, static performance, and robustness of the system. The proposed strategy stability is investigated under Lyapunov theory. A comparative simulation of the new proposed approach with the conventional SMC and PI controller display the excellent performance, stability and high robustness of FOSMC, by improving the system efficiency up to 98.66%, compared to conventional SMC with 91,14%, while the PI control achieves 86, 2%.
Effect of Lean Practices on Lead Time Reduction
Authors: Et. al. Bouchra Hafiane,
Published: April 2021

This article presents a study on the effect of Lean practices on lead time reduction. In this study, we have proposed the consideration of human, technical and environmental factors in the study of the impact of production scheduling and SMED on manufacturing lead time. Based on the fact that scheduling and SMED go well beyond a calculation function. From our point of view, it is preferable to broaden the field of study of this impact by going beyond the fields of mathematics, operational research and artificial intelligence. In this study, we propose to start from the idea that there are other factors that can influence the expected results, namely human, technical and environmental factors. To achieve this, we went through a literature review and then tried to validate our hypotheses through a quantitative study.

Authors: Et. al. Ibrahim Assabane,
Published: April 2021

Faced with cumulative competition linked to the globalization of markets, and increasingly strong demands in terms of performance, many firms are led to ask the question of relocating either part or all of their activities. Relocation is a strategic decision which obliges companies to review and reconfigure their operations management methods, in particular those concerning the supply chain. The working objective is to identify the key factors to take into consideration for the design of the supply chain in the context of delocalization. First, we tackle the problem of defining delocalization and the supply chain. Next, we review the literature to define the specifics of the problem of relocation and their impact on international trade, notably the case of Morocco, and thus identify all the factors and constraints to be taken into account when reconfiguring the global supply chain in order to adapt it to the context of the practice of intelligent delocalization.

Hybrid Broadcast Encryption and Group Key Agreement Protocol with Precise Cipher Texts
Authors: Et. al. Chinnala Balakrishna,
Published: April 2021

In cryptographic system so as to manage the group of members, the group key management protocol is used and it also should provide the security to the group of members which means the communication among the members will be done in secure manner. Broadcast Encryption (BCE) provides a key it arise common for all the members in the group during the encryption and all the associated members can decipher the message with the same mutual key but cannot stop decrypt the message by individuals. Broadcast encipher algorithm sends a secure transmit note to the entire members with the distributed key to decrypt the message with trusted third party. The conventional BE scheme fully relies on third party reliable key generator server machine, the responsibility of the third party server is to generating the undisclosed deciphering keys for the entire collection members and the group members are responsible for decrypt the messages which are encrypted under a common encrypted key. The purpose of Group Key Accord (GKAP) protocol is for negotiate all the assembly members and designing a familiar encryption key through the network. With the GKAP the group members are responsible for generating universal encipher key and it permits simply the group people to decrypt the cipher text which is encrypted by group members by using the shared encryption key but this GKA protocol it is not possible to exclude any members from the group to decrypt the cipher text shared under the common encryption key. In this paper we will combine these two techniques to produce a novel approach called as the Hybrid Broadcast Encryption (HBCE). In this innovative primeval all the cluster of participants agree and produces a widespread encipher key but though each individual having their own decipher key, So that the sender by looking the encryption key he will bound the deciphering to limited members for his abundance.

The MI-SDN System to Manage MQTT Data in an Interoperable IoT Wireless Network
Authors: Et. al. Rajae Tamri,
Published: April 2021

The main challenge for the Internet of Things (IoT) is to ensure interoperability between heterogeneous IoT entities. To support the interaction, intercommunication, and interoperability between these devices several solutions are proposed in the literature. The SDN (Software-defined Network) is one of these solutions to resolve the problem of the heterogeneous network used in IoT. To guarantee network interoperability, the SDN uses a centralized controller, which handles the entire network. The role of end devices in IoT is only forwarding data. The MQTT (Message Queuing Telemetry Transport) protocol is another solution for granting interoperability in IoT. Which is a publish/subscribe based messaging protocol that avoids direct connection between devices by relaying data through a central server called the broker. Combination of these two solutions to manage IoT devices makes it easy to add new devices without touching or changing the existing infrastructure. The new devices only need to communicate with the broker. Moreover, the Controller SDN is responsible for handling networks. Consequently, smart devices added don’t need to be compatible with the others. In this paper, we present the design and the implementation of a new IoT architecture, which is a combination of SDN technology and MQTT protocol. That enables heterogeneous IoT devices to be interoperable and interact without any problems. Our system utilizes the lightweight protocol MQTT with a new mechanism using several slave brokers and one master. The slaves manage the group of the end devices in the wireless IoT network, and the master broker installed in the SDN controller supervises the integral network. The SDN controller uses a multicast system to send MQTTdata across the external wireless network. As a result, that reduces transmission delay between wireless IoT network compared with the using of a standard MQTT.
Target Tracking in Wireless Visual Sensor Networks: Challenges, Steps, and Metrics of Evaluation
Authors: Et. al. Afaf Mosaif,
Published: April 2021

In recent years, wireless sensor networks have been used in a wide range of applications such as smart cities, military, and environmental monitoring. Target tracking is one of the most interesting applications in this area of research, which mainly consists of detecting the targets that move in the area of interest and monitoring their motions. However, tracking a target using visual sensors is different and more difficult than that of scalar sensors due to the special characteristics of visual sensors, such as their directional limited field of view, and the nature and amount of the sensed data. In this paper, we first present the challenges of detection and target tracking in wireless visual sensor networks, then we propose a scheme that describes the basic steps of target tracking in these networks, we focus then on the tracking across camera nodes by presenting some metrics that can be considered when designing and evaluating this type of tracking approaches.

Technology transfer is a powerful growth factor in industrial value added in the processing industries. Of course, it is important to assess the efficiency of technology transfer in the processing industry by analysing its influencing factors and discussing strategies to improve technological innovation. However, it is still difficult to measure its direct impact on the improvement or creation of value added, and one of the most relevant indicators that could measure the real impact of technology transfer is efficiency. The efficiency of the modes of technology transfer will therefore be the comparative relationship between inputs and outputs in the technology transfer activities based. It is an indicator for measuring the profitability of technology investment in industrial transformation. In our study, we will try to integrate a mathematical tool that allows us to solve optimization problems using a program operating under different constraints imposed by a model. The usefulness of this model depends on the ability to implement it, by the managers of production lines who are called upon to implement R&D, innovation or technology transfer projects. Based on panel data of processing industries that use one or more modes of technology transfer in the Souss-Massa region, this article will examine trends in the efficiency of technology transfer use, mainly as a result of technological progress and the promotion of technology transfer.

These techniques empower us to assess a particular degree of normal compounds, much the same as benzene, toluene and xylene, and so on. One notable part of all types of signal systems is the flexibility of adaptation. And spatial exactness isn't fundamental to get a range from an expansive number of fragrant compounds where more prominent characterization and statistical mean are more critical. Moreover, sufficiently low deviations of the expected values were achieved from the true values. The standard deviation, to determine the properties of fragrant compounds and compare them with normal compounds isn't thorough. A persistent baseline rectification was performed; after that, the rectified spectrum was normalized to their area and somewhat smoothed. The autofluorescence foundation was subtracted, for the pure range analysis, by utilizing scientific approaches: polynomial estimation (PolyFit) and (method Processors Gases Improved). The accuracy obtained is not extreme and can be increased by developing algorithms and selecting other parameters. It is also possible to increase the accuracy and reliability of this method by improving the quality of the training sample by eliminating the unwanted data that we have obtained, by increasing the sample size, and by studying more in detail the sample data to eliminate inaccuracies that arise during the transition between concentrations Gas.

: The Artificial Neural Network (ANN) is an Artificial Intelligence technique that offer many benefits including the ability to process a vast amount of data, the ability to learn from experiences, and the good generalization capability. It was invented based on the concept of imitation of the human brain and built up of nodes that are like human neurons. The Radial Basis Function (RBF) is one of the established types of ANN. Considering the advantages and great performance of the RBF, this study aims to investigate the contributory factors of students’ learning habits during the Coronavirus Disease 2019 (or known as COVID-19) pandemic using RBF. Responses from a total of 420 respondents were collected from Vietnamese students’ learning habits during the COVID-19 pandemic dataset that was established from the questionnaires distributed in the period of 7th February 2020 to 28th February 2020. Fifteen independent variables were used as the input for the RBF network which is based on the 15-9-1 structure. Based on the experiment conducted, the implementation of the RBF model was found to be fair and effective with the small number of Sum of Square Error (SSE) and Relative Error (RE) produced. It could also be concluded that the most contributing factor of students’ learning habits during the COVID-19 pandemic is the learning hours per day for self-learning before the pandemic.

Social media is increasingly becoming a key platform in disseminating information to the masses. With its free platform and wide audience penetration, various topics are shared across which also includes promoting environmental awareness. However, just like various other topics, any digital information constantly competes for user attention and consumption. The information design strategy put in place must be understood to assess user perception towards the content where a well-designed information will motivate users to like and share content. A study employing Instagram post-type categorization and survey probing user perception was carried out in the context of NGOs championing recycling efforts. The findings show that users prefer visualized information. The results can be used as a guideline for digital information designers to improve the information design technique particularly in the context of creating awareness that could potentially dive into virality element fitting with user perception and preferences.
Learning Through Games: An Approach for Children with Autism Spectrum Disorder During COVID-19 Pandemic
Authors: Et. al. Nurul Hidayah Mat Zain,
Published: April 2021

The coronavirus disease (COVID-19) pandemic has led to increased online learning for students, including children with Autism Spectrum Disorder (ASD). However, the need for social distancing has interrupted the delivery of continuing education for ASD children. ASD emerges in early childhood, which may cause interruptions in numerous essential areas of progress in daily life. Therefore, we proposed a mobile game, namely Basic Daily Life (BasLife) game, for ASD children. The game offered positive affection and an enjoyable experience in learning sessions during the COVID-19 pandemic. The Rapid Application Development (RAD) methodology was implemented to produce the BasLife game. The RAD methodology consists of four phases: Requirement Planning Phase, User Design Phase, Development Phase, and Cutover Phase. The EGame Flow Model was applied as a guideline to develop an enjoyable game during the User Design Phase and Development Phase. Keenly, the study results produce theBasLifegame as a learning approach for ASD children that would tackle the interpersonal skills and create an enjoyable learning experience during the COVID-19 pandemic.
Automated Evaluation ofTelugu Text Essays Using Latent Semantic Analysis

Published: April 2021

The most productive strategy to improve students' ability to write is to have direct and as much as possible teacher input. However, the workload of the teacher is greatly increased. Automated systems are increasingly required to help students write essays. In the field of educational assessment technology, automated test evaluation is becoming more and more common. We present a framework that is modelled on the programme, following which the school-teachers in the BPDAV School and Govt. High School Hyderabad, Telangana, India present the automatic evaluator of student essays in the Telugu language.  Language skills; the structure of the essay and the contents that fit the subject are the principal requirements for evaluating the essays. In this context, we have established a scheme focused on latent semantical analysis and the theory of rhetorical structure. The method has been evaluated in more than 600 different essays, written in different manuscripts by schoolchildren. Overall 0.82 with the teacher's assessment was achieved in our method.
Investigation of Influence ofa New Twist Intensifier on the Properties of the Twisted Yarn

Published: April 2021

The article is devoted to the study of the properties of the yarn obtained by the methods of ring and rotor spinning, for twisted yarn, produced on a VTS-09 double twist machine made by Volkmann (Germany). Experiments were carried out on two typesof spinning yarns with yarn counts Ne 20/2 and 12/2 in the existing design (control) and the new design, flexible element with equal tension and twist intensifier and compared the effects of the resulting twisted yarn for quality parameters. Mathematical statistical methods (single-factor analysis of variance) were used to assess the quality of twisted yarn. Experiments have shown that the use of a new design nozzle reduces the vibration of the yarn, which leads to a uniform distribution of twists along the length of the twisted yarn, increases its tensile strength and improves the quality of the twisted yarn.
