Comparative Study of the Development of Android-Based Flipped Classroom Model between Jeddah and Indonesia

The development of information communication and technology has brought a new paradigm of education globally and particularly in Indonesia. Face to face learning has some limitations in terms of understanding, space, and time. The general concept of the flipped classroom method is that the students learn the materials at home and do the reinforcement in the classroom as well as learn the materials they yet to understand. The teacher dominates the learning process verbalism and stressful due to the overload materials in time limitation. This leads to teachers’ unawareness of the student's understanding. Therefore, in Industry 4.0, the learning process internet-based become the primary alternative to overcome the gap. Android-based flipped classroom model is one of the chosen solutions in this research to develop the online teaching media and learning materials. The research aimed to compare the effect of the Android-based flipped classroom model against the students' achievement in one of the schools in Jeddah and Indonesia. Research and Development (R&amp;D) adapted from Dick and Carey used in this research. The development of an Android-based flipped classroom model effectively implemented in Indonesia but did not effectively implement in Jeddah. The results showed that the students' achievement for Indonesian students was significantly higher than of Jeddah students. However, both students and teachers in both schools showed a positive response to the Android-based flipped classroom model.
Distributed Ledger Technologies and the Internet of Things: A Devices Attestation System for Smart Cities

Traditional IT security mechanisms are generally not well suited for IoT devices, where processing and network connectivity should be kept to a minimum.Consequently, IoT devices have been recently identified as an easy target for cyber-attacks, like for example on the Mirai botnet Distributed Denial of Service attacks in 2016, where various devices were hacked into and taken over.Different solutions have been developed aiming at guaranteeing the security at both the device application layer and the network layer.Few succeeded to deliver the flexibility necessary for IoT devices.Even fewer have implemented an effective threats detection system, and just a handful have realised all the previous features in a fully decentralised fashion, including this one.This Distributed Ledger Technology (DLT) attestation system is maintained and supported by most, or all, IoT devices because it is based on a light-weight DLT protocol.It comprises of a system for authorisation and authentication for the individual devices as well as includes an anomalies detection system based on smart contracts.A demonstration was built to support a Smart City use case.The objective is to guarantee, in a decentralised manner, the security of low computational power devices executing the sensing function and their connectivity, and therefore the correct functioning of the system.On the demonstrator, the system was run using DLT supported by the sensors connectivity bridge (built using Raspberry Pi's).The system proved to be rapid to develop, flexible with regard to systems changes and resilient to attacks to both individual IoT devices and to the DLT.

On the Capability of QoE Improvement Based on the Adjustment of RLC Parameters

The constant evolution in mobile communications networks have led operators to seek new techniques to optimize their mobile networks with the objective of satisfying the expectations of the users. In this way, traditional optimization techniques based on improving radio indicators, have given way to new techniques based on improving the quality of experience (QoE) perceived by users. This paper is focused on analyzing the impact of the adjustment of radio link control (RLC) layer configuration parameters on the QoE perceived by the users of two different types of services. Firstly, an evaluation of the QoE experienced by the user of a real-time video streaming service with respect to the transmission buffer size of the RLC layer in unacknowledged mode (UM) has been carried out. Secondly, the QoE perceived by the user of a file transfer service in relation to the variation of the configuration parameters of the RLC layer in acknowledged mode (AM) has been evaluated. The study, which has been carried out in a simulated cellular environment, has been performed for different system bandwidth values, thus proving the relationship between the QoE perceived by the users, the optimal RLC configuration parameters values and the available bandwidth.
Practical use of electronic health records among patients with diabetes in scientific research

Electronic health (medical) records, which are also considered as patients' information that are routinely collected, provide a great chance for researchers to develop an epidemiological understanding of disease. Electronic health records systems cannot develop without the advance of computer industries. While conducting clinical trials that are always costly, feasible and reasonable analysis of routine patients' information is more cost-effective and reflective of clinical practice, which is also called real world study. Real world studies can be well supported by big data in healthcare industry. Real world studies become more and more focused and important with the development of evidence-based medicine. These big data will definitely help in making decisions, making policies and guidelines, monitoring of effectiveness and safety on new drugs or technologies. Extracting, cleaning, and analyzing such big data will be a great challenge for clinical researchers. Successful applications and developments of electronic health record in western countries (eg, disease registries, health insurance claims, etc) have provided a clear direction for Chinese researchers. However, it is still at primary stages in China. This review tries to provide a full perspective on how to translate the electronic health records into scientific achievements, for example, among patients with diabetes. As a summary in the end, resource sharing and collaborations are highly recommended among hospitals and healthcare groups.
A Hybrid Secure Keyword Search Scheme in Encrypted Graph for Social Media Database

Privacy preservation is a challenging task with the huge amount of data that are available in social media. The data those are stored in the distributed environment or in cloud environment need to ensure confidentiality to data. In addition, representing the voluminous data is graph will be convenient to perform keyword search. The proposed work initially reads the data corresponding to social media and converts that into a graph. In order to prevent the data from the active attacks Advanced Encryption Standard algorithm is used to perform graph encryption. Later, search operation is done using two algorithms: kNK keyword search algorithm and top k nearest keyword search algorithm. The first scheme is used to fetch all the data corresponding to the keyword. The second scheme is used to fetch the nearest neighbor. This scheme increases the efficiency of the search process. Here shortest path algorithm is used to find the minimum distance. Now, based on the minimum value the results are produced. The proposed algorithm shows high performance for graph generation and searching and moderate performance for graph encryption.
Robust Visual Tracking via a Collaborative Model Based on Locality-Constrained Sparse Coding

Target tracking is an important task in computer vision. Now many tracking algorithms have achieved great results. However, several challenges still hinder the development of tracking algorithms, such as abrupt motion, occlusion and so on. In order to use the feature information of the target more effectively and improve the accuracy and robustness of target tracking, a novel model is designed which is different from the previous discriminative component and generative component, and a novel discriminative-generative collaborative appearance model is presented to combine the two components in this paper. First, for the discriminative component, Locality-Constrained Sparse Coding Algorithm is proposed. In this algorithm, the objective function of the local feature of the target spatial information is determined by fusing the pyramid maximum pool and local feature histogram method. The objective function has three important parameters, which are solved by different optimization strategies. Second, for the generative component, the Histogram of Locality-Constrained Feature Algorithm is proposed. In this algorithm, the locality constraint is served to describe the spatial information of the target as a generative appearance model. Each image patch can be approximated by a linear combination of a local coordinate system formed by a dictionary whose elements are cluster centers that contain the most representative model of the target. Third, this paper designs a collaborative target tracking framework based on semi-supervised learning algorithm with locality constraint coding. The framework can quickly and robustly determine the feature information of the tracking region. The proposed algorithm is evaluated on the comprehensive test platform. The experimental results show that our method is more robust and efficient, and the precision and success rate of our algorithm are improved by 5.4% and 4.7%, respectively.
Mineralogy and geochemistry of Mishrif Formation from selected oilfield, south east of Iraq

Mishrif Formation (Late Cenomanian) has been studied in four oilfields in southern Iraq, and studied samples were examined by mineralogy and geochemistry analysis using XRF and XRD techniques.&#x0D; The mineralogical study reveals that dolomite and calcite are the main minerals in the rock formation in studied oil fields, whereas quartz and clay minerals (kaolinite, montmorillonite and illite) represent secondary minerals composition. For geochemical classification of Mishrif rock, Ca/Mg ratio was applied and this reveals that Calcitic Limestone is a major type in studied samples.&#x0D; The paleo - salinity has been examined by using Ca/Mg and Mg/Ca ratios and they referred to moderate salinity during deposition. Mg/Ca and Mn/Ca ratios have been applied to measure paleo-temperature, so infer a moderate paleo-temperature for Mishrif Formation in studied samples. Based on the comparison between low Sr/Ca and the relatively high Ca/Mg ratios, infer that a dolomitization process played the main role among diagenesis processes.&#x0D; &#x0D; http://dx.doi.org/10.25130/tjps.25.2020.013
Femtosecond laser direct writing of optical quantum logic gates

Unlike classical digital computers in which a bit can represent either 1 or 0 at any time, quantum computers use a two-level system, i.e., a qubit, to implement logical operations based on quantum mechanical laws, which can represent both values at once. Owing to the superposition property of qubits, quantum computers have natural parallel processing advantages and thus have potential to exceed the computational efficiency of classical computers for particular tasks. Quantum logic gates are the generalization of classical logic gates in computational networks. It has been proved that two-qubit quantum gates together with one-qubit quantum gates are adequate for constructing networks with any possible quantum computational property. Directional couplers are the most critical elementsfor constructing the quantum gates. In recent years, photonic quantum technologies have emerged as a promising experimental platform for quantum computing. Single photons have robust noise resistance, long coherence time, high transmission speed and great compatibility with other systems. They can be easily manipulated and encoded in any of several degrees of freedom, for example, polarization, path, spatial mode or time bin. Optical waveguide technology enables the realizing of complex optical schemes comprised of many elements with desired scalability, stability and miniaturization. Femtosecond laser direct writing of waveguide has been adopted as a powerful tool for integrated quantum photonics with characteristics of rapidness, cost-effectiveness, mask-less and single-step process. In particular, it has the ability to build arbitrary three-dimensional circuits directly inside bulk materials, which is impossible to achieve with conventional lithography. In this article we review the femtosecond laser writing and quantum characterization of directional coupler and important one-qubit and two-qubit optical quantum logic gates, such as Hadamard gate, Pauli-X gate, controlled-NOT gate, and controlled-Phase gate. The qubits in these gates are usually encoded through optical paths or polarizations of photons. The key to the realization of polarization-encoded one-qubit gates is to achieve flexible wave-plate operations, which is described in detail. Controlled-NOT gate and controlled-phase gate are the most crucial two-qubit gates in the linear optics computation and sometimes they can be converted into each other by adding some one-qubit gates or special superposition states. Many different kinds of waveguide circuits have been used to implement these two-qubit gates. The outlook and challenges for the femtosecond laser writing of three-qubit gates, such as Toffoli gate and Fredkin gate, are briefly introduced.

Design and Implementation of Control Algorithms for Single-Axis Sun Tracking Systems

Solar energy is the most widespread renewable energy source due to the modular structures of PV modules and low maintenance requirement. In this study, a sun tracking system is proposed with a view to achieving a generated energy output than with a fixed PV system. There are two different control structures and algorithms are proposed to control the sun tracking system to increase efficiency. The tracking system uses algorithms to determine the exact position of the sun at any time during the day and to turn the PV modules to a position perpendicular to the sun. In the first control circuit, the position of the sun is precisely found with two identical LDRs and an angle sensor. In the second control circuit, the position of the sun is tracked by using a real time clock and an angle sensor to limit the platform. Greater energy generation is achieved by turning existing solar panels to face the sun. Furthermore, a data acquisition device stores and monitors daily irradiation data on a computer and the data entered in the database are used to produce graphic interfaces.
Studi Pustaka Tentang Kerentanan Keamanan E-Learning dan Penanganannya

E-learning is an educational media that use ICT in the learning process. Nowadays, most of the higher education (universities) in Indonesia have integrated the learning process with e-learning systems. By using this system, learning can be done outside the classroom, anytime and anywhere. Based on the literature reviews, e-learning has many positive impacts on higher education components and its ecosystems, i.e., students, lecturers, higher education staff, and campus officials. Although it offers many advantages, similar to the information technology in general, e-learning systems are also vulnerable to security issues. Because, several security holes in the system can be penetrated easily by hackers, where the essential data contained in e-learning has high potential to be spoofed even modified by irresponsible parties. The security aspect of the e-learning system must be considered to minimize risks. Thus, the higher education can run their business as well. This paper aims to elaborate on the e-Learning system, opportunities, challenges, and several offered solutions on it. The research method used in this paper is literature studies from the latest references

A Novel Physical Machine Overload Detection Algorithm Combined with Quiescing for Dynamic Virtual Machine Consolidation in Cloud Data Centers

Further growth of computing performance has been started to be limited due to increasing energy consumption of cloud data centers. Therefore, it is important to pay attention to the resource management. Dynamic virtual machines consolidation is a successful approach to improve the utilization of resources and energy efficiency in cloud environments. Consequently, optimizing the online energy-performance trade off directly influences Quality of Service (QoS). In this paper, a novel approach known as Percentage of Overload Time Fraction Threshold (POTFT) is proposed that decides to migrate a Virtual Machine (VM) if the current Overload Time Fraction (OTF) value of Physical Machine (PM) exceeds the defined percentage of maximum allowed OTF value to avoid exceeding the maximum allowed resulting OTF value after a decision of VM migration or during VM migration. The proposed POTFT algorithm is also combined with VM quiescing to maximize the time until migration, while meeting QoS goal. A number of benchmark PM overload detection algorithms is implemented using different parameters to compare with POTFT with and without VM quiescing. We evaluate the algorithms through simulations with real world workload traces and results show that the proposed approaches outperform the benchmark PM overload detection algorithms. The results also show that proposed approaches lead to better time until migration by keeping average resulting OTF values less than allowed values. Moreover, POTFT algorithm with VM quiescing is able to minimize number of migrations according to QoS requirements and meet OTF constraint with a few quiescings.
Young Age and Crime in Society: A Study on Youth Prisoners in Bangladesh

In a given society, crime is a social phenomenon and an inconsistent act of social order. Engagement of young boys and girls in diverse criminal activities is becoming a universal and more complicated issue in human society. The involvement of youths in different types of crimes is also becoming a major concern in Bangladesh. Hence, this study aimed to investigate the factors influencing the young prisoners in the involvement of various criminal activities. The major theoretical perspectives of criminology, including Strain Theory, Differential Association Theory, Social Disorganization Theory, and Labeling Theory, were used to provide explanations for causes of criminal behavior among young prisoners. The study was conducted employing a mixed approach, that is, taking into consideration both quantitative and qualitative methods because of its nature and subject matter. A survey was carried out by using a structured questionnaire. Moreover, in-depth interviews were carried out to have a deeper understanding of the phenomena under study. The study found that while problematic family relationship and family crisis is the main driving factor influencing the young prisoners for committing the crime, other factors including the influence of neighborhood, peers, poverty, media and social reaction towards individual have also played an influential role.
