Analysis of surface electromyography for hand gesure classification

&lt;span lang="EN-MY"&gt;Electromyography (EMG) is the measure of electrical activity produced by skeletal muscle. It is useful in prosthetic and rehabilitation technology as well as ability to handle electronic devices and robotics. If the EMG signal from the body especially hand movement can be apprehended, better value for people all around the world can be provided. Furthermore, it can be used to control smart-phone and be integrated with wearable technology. Another interesting application of this technology is in sign language recognition which is able to assist many disabled people in their daily lives. In this paper, hand gesture signals are acquired, extracted, analysed and classified. The EMG data from hand gesture which are rock, paper and scissors managed to be extracted. We use time domain feature to classified using Principal Component Analysis and regression tree. The result was highly accurate with 72.59% and 80.85% for PCA and regression tree respectively.&lt;/span&gt;
Quantum computing programming languages

In this Thesis we analyze the quantum software developed by IBM and Google, respectively Qiskit and Cirq. It is reviewed how to program a simple quantum algorithm on both software and they are compared. In order to test their performance, we implement a circuit to verify particular N-qubit entangled states, called GHZ states, in both software. In fact, one of the main goal of quantum computation, and of quantum science in general, is the creation of a highly entangled state of many particles, because entangled states are the cornerstone of quantum speedups. We quantify the goodness of the state created through fidelity measurements. These provide a fundamental criterion for the comparison of two quantum states. We test the quantum circuit on the cloud service made available by IBM. In Cirq, no cloud service is yet available, therefore we test that circuit adding quantum noise channels, in order to reproduce and study noise effects in a model of real hardware.

Overlapping issues and solutions in data visualization techniques

&lt;span&gt;The tremendous growth of big data has caused the data visualization process becomes more complex and challenging, and yet, data is expected to be increased from time to time. With these massive and complex data, it is getting harder for the data analyst to interpret or read the data in order to gain new knowledge or information. Therefore, it is important to visualize these data using different techniques. However, there are many remaining issues in data visualization techniques. These issues make the data visualization a big challenge to the data analyst. The most common issue in data visualization techniques is the overlapping issue. This paper reviews the overlapping issues in multidimensional and network data visualization techniques. The existing solutions are also reviewed and discussed in term of advantages and disadvantages. This paper concludes the advantages of the overlapping issues and solutions, before discussing their drawbacks. This paper suggests the color-based approach, relocation, and reduction of data sets to solve the overlapping issues.&lt;/span&gt;

Simple Noninterference by Normalization

Information-flow control (IFC) languages ensure programs preserve the confidentiality of sensitive data. Noninterference, the desired security property of such languages, states that public outputs of programs must not depend on sensitive inputs. In this paper, we show that noninterference can be proved using normalization. Unlike arbitrary terms, normal forms of programs are well-principled and obey useful syntactic properties-hence enabling a simpler proof of noninterference. Since our proof is syntax-directed, it offers an appealing alternative to traditional semantic based techniques to prove noninterference.

Training of Future Teachers of the Russian Language as Native and Foreign: Problems and Ways of Overcoming Them

The study of the Russian language, its distribution, and preservation in many respects depend on specialists in the field of philology, in particular, teachers who are working not only in Russia but also abroad. Currently, the problem of training future teachers of the Russian language as a native and as a foreign language has become relevant. After graduating from the university, students do not want to work according to the profession. The purpose of the study is to reveal the problems associated with the training of future teachers of the Russian language in Russian universities and to determine ways to solve them. For this purpose, several methods were used: complex theoretical analysis, observation, social and pedagogical, basic and diagnostic, pilot pedagogical studies. During the research, more than 300 participants from different countries of the world took part. The problems that are demonstrating why students choose the philological faculty were identified. Then, the motivation to master their future profession disappears. The solutions of problems based on a pedagogical experiment are offered, i.e. development of special courses, testing modern technologies that allow building the process of teaching professional activity taking into account the clip thinking of students and multicultural environment of the University. The conclusions presented in the article aim teachers at the active creative process directed at the development of motivation of students to mastering future profession in the system of higher education of the Russian Federation.

An iterative reconstruction algorithm for pole figure inversion using total variation regularization

This paper describes a new discrete method for inverting X-ray pole figures to estimate the orientation distribution function (ODF). The method employs the equal-volume `cubochoric' representation for uniform discretization of orientation space, SO(3). The forward-projection model is combined with an anisotropic total variation term to iteratively determine the ODF. The efficacy of the new method is evaluated with both model and experimental data and compared with existing discrete and series expansion methods.
A Composite Discriminator for Generative Adversarial Network based Video Super-Resolution

Generative Adversarial Networks (GANs) have been used for solving the video super-resolution problem. So far, video super-resolution GAN-based methods use the traditional GAN framework which consists of a single generator and a single discriminator that are trained against each other. In this work we propose a new framework which incorporates two collaborative discriminators whose aim is to jointly improve the quality of the reconstructed video sequence. While one discriminator concentrates on general properties of the images, the second one specializes on obtaining realistically reconstructed features, such as, edges. Experiments results demonstrate that the learned model outperforms current state of the art models and obtains super-resolved frames, with fine details, sharp edges, and fewer artifacts.

TEKNOLOGI FIREBASE UNTUK APLIKASI LAPOR AKAKOM

The mechanism for conveying aspirations in STMIK AKAKOM by academicians and how the responses given have not been able to run well. This happens because the media used to convey these aspirations are only through suggestion boxes or by conveying them directly to the parties concerned. The follow-up given by the related parties was felt to still take a long time. There fore, the application of aspirations and information is needed to accommodate the aspirations and dissemination of information by utilizing Firebase technology. Some features used in making this application are Firebase Firestore to make data updates in real time and the application can be used offline. Firebase Cloud Messaging is used to create push notifications. This application is divided into two parts. The web-based application functions to manage information and aspirations used by the admin of STMIK AKAKOM and the Android-based application functions to receive information and send aspirations to be used by STMIK AKAKOM students.  The results of this study are the application of aspirations and information by utilizing Firebase technology. From the testing that has been done, it is obtained that the application can function as an application to manage student reports and aspirations.
Handwritten Word Searching by Means of Speech Commands Using Deep Learning Techniques

Word searching is a topic that has gained great interest due to the development of numerous techniques focused on this task. However, most of those implementations require a prior digitalization or preprocessing of the target text so, it cannot be done in real-time, or do not locate the word requested within the text or image, making the user search the word by their own. For that reason, in this paper, it has been proposed to develop an application focused on locating handwritten words in real-time, i.e. a webcam acquires the image continuously and the application searches for the word required by the user, indicating how many times the word is in the image and their respective location. The work has focused on detecting 10 words in the Spanish language. For this development, two recognition systems have been implemented. The first one is for speech recognition, in such a way that it is not required to enter the search by means of a keyboard, but that the selection is made using an audio input in charge of recognizing what word the user says; this is done by means of a convolutional neuronal network, whose accuracy has been 90% and is responsible for telling the application what the said word by the user. The second system is to detect and locate the words in the image acquired by the webcam, where a Faster R-CNN is used, validated with 98.9% accuracy in the words found. In order to verify the performance of the application, tests have been performed in real-time, showing the capacity it has, correctly identifying the word spoken by the user and locating with great precision each word found in the captured image.
Exploring the difficulties in teaching an expression content area and improvement teaching methods for elementary school teachers

The purpose of this study was to identify the difficulties of elementary school physical expression activity classes and to explore ways to improve them for effective teaching practice. To this end, a class of sixth graders in elementary school was selected as an example as a single case study method. Twenty-seven students, including the homeroom teacher (15 boys and 12 girls), were selected as participants in the study to examine the difficulties of the expressive activity class through class observation, in-depth interview, focus group interview, etc. Studies identified the teacher’s difficulties as ‘a situation in which a teach must teach something he or she does not’, ‘not having the opportunity to acquire knowledge and functions related to expressive activities’, ‘a class environment that makes it impossible to teach expressive areas’ and ‘a reality that does not need to teach expressive areas’. As an improvement ways for effective practice of expression activity class, it was presented with cooperation with dance teachers, support of the professionalism of elementary teachers, preparation of the environment that enables to teach an expression area, and motivation of teachers to into teaching an expression area.
Mitigating Examination Malpractices in Nigerian Universities using an Enhanced Automated Essay Scoring System

Education, being a process of teaching and learning is evaluated through examination at the end of the learning period.Examinations not only serves as a feedback for the trainer to ascertain the level of knowledge acquired but also serves as a measure of knowledge retention by the trainee.Any misconduct or irregularity distorts this feedback mechanism and gives a false outcome of the learning process and has negative consequences.In Nigeria, examination malpractice has reached an alarming stage and in recent times this concern has been echoed across the country.Many suggestions on containing the crisis focus on correcting the attitude of students, teachers and the government but the situation seems to have worsened as implementation of these recommendations remain a challenge.In this research, an alternative approach which is the use of Automated Essay Scoring technique for assessing student's examinations is proposed.This approach would significantly discourage examination malpractice and provide better control, accuracy and efficiency in examinations.
초등학교 과학 디지털교과서에 제시된 테크놀로지를 활용한 탐구 활동의 특징 - 가상실험, 가상현실, 증강현실 활용 사례들을 중심으로 -

The purpose of this study is to investigate the features of inquiry activities using technology in the 2015 revised elementary science digital textbooks. For this, we analyzed the features of inquiry context and inquiry method presented in inquiry activities using three kinds of technology: Virtual experiment, virtual reality and augmented reality. As a result, firstly, the most common types of 77 inquiry activities were realistic type which shows the phenomenon actually and vividly as possible and realistic-abstract type which shows the phenomena with the abstract concepts. Second, the ways of using three technologies were different depending on the processes of inquiry and the sub-domains of science. For example, virtual experiment technologies were mostly used in the contents of physics and chemistry with the inquiry context of realistic-abstract type for investigating the relationship between variables of experiments and describing the phenomena mechanically. On the other hand, virtual reality and augmented reality techniques tended to be used more frequently in biology and earth science contents with the inquiry context of realistic type for observing and describing the phenomena. Finally, we discussed educational implications in terms of developing and applying technology-based inquiry activities.
