A MATLAB model for diagnosing sickle cells and other blood abnormalities using image processing

&lt;span lang="EN-US"&gt;The conventional method for detecting blood abnormality is time consuming and lacks the high level of accuracy. In this paper a MATLAB based solution has been suggested to tackle the problem of time consumption and accuracy. Three types of blood abnormality have been covered here, namely, anemia which is characterized by low count of red blood cells (RBCs), Leukemia which is depicted by increasing the number of white blood cells (WBCs), and sickle cell blood disorder which is caused by a deformation in the shape of red cells. The algorithm has been tested on different images of blood smears and noticed to give an acceptable level of accuracy. Image processing techniques has been used here to detect the different types of blood constituents. Unlike many other researches, this research includes the blood sickling disorder which is epidemic in certain regions of the world, and offers a more accuracy than other algorithms through the use of detaching overlapped cells strategy.&lt;/span&gt;

The experience of student self-government in improving the quality of the educational process

The article considers the organization of self-government in higher education. This means voluntary and independent public activities of students to perform the functions of management of higher education, which is determined by its administration. Along with the main tasks of student self-government bodies to ensure and protect the rights and interests of students, it must ensure the performance of duties, influence the discipline and effectiveness of education. Democratic principles of election to these bodies, their effective functioning, and the provision of guarantees are a prerequisite for integration into the Bologna Agreement. The main problems in this are the need to improve the legal framework of the educational process, low financial resources, lack of democratic political culture, the mechanism of interaction with the administration and the passivity of students. Research on the issue shows a lack of awareness of the performance of student government and a low level of trust and authority of its leaders. Instead, the experience of European universities shows in favor of these bodies in solving university-wide cases. Strong material base and financial and legal independence from the administration of the educational institution allow to independently distribute part of the funds for financing grants from student societies and associations at the university. The influence of teachers on the process of formation of future specialists in terms of application of practical experience and modern management technologies is important. Thus there is a formation of the developed personality, stimulation of activity of the future citizen, education of the tolerant interlocutor. The conclusion is made about the importance of student self-government bodies whose activities are aimed at improving the educational process, organizing cooperation with students of higher education institutions and youth organizations, cooperation with managers and executors of projects of various levels, using the practical experience of teachers on the principles of collegiality in order to improve the quality of education.

Study of the System of Scientific and Scientific-Technical Activities of Agrarian and Economic Universities

Universities, being the center of highly qualified scientific and pedagogical personnel, have the opportunity to create scientific schools, attract young scientists to a scientific career and form a scientific elite among gifted students, thus integrating theory and practice, science and education, influencing the development of scientific knowledge. Scientific potential, the development of fundamental and applied science are criteria for the competitiveness of universities in the educational services market. Thus, it is relevant to find effective ways to train scientific personnel and comprehensively study systems of scientific and scientific-technical activities of universities. The purpose of this study is to compare scientific and scientific-technical activities of agrarian and economic universities in Russia, Kazakhstan and Bulgaria, where personnel is trained for one of the leading industries in these countries. An anonymous online survey based on a specially designed questionnaire was conducted; it involved 162 respondents from the countries above - scientific and pedagogical staff of agrarian and economic universities. The results of the present study, in comparison with the data of scientific literature, allow one to assert that the common global problems in universities are unstable funding and a decline in the prestige of a scientific career. The latter makes it difficult to attract young people to science, leads to aging of scientific personnel, dissatisfaction with work, and the risk of professional burnout. At the same time, fierce competition imposes increased requirements on the quality of universities' scientific products and their promotion in the market of research and scientific-pedagogical services. A feature of the modern world is the integration of scientific and scientific-technical activities of individual higher educational institutions into the international scientific environment, which not only provides new opportunities for research, the development of human resources, and mastery of new high technologies, but also exacerbates the problem of compliance with bioethical norms and academic decency, management of scientific resources and protection of intellectual property at all levels. As a result of the research, general and distinctive features of scientific and scientific-technical activities of agrarian and economic universities of Russia, Kazakhstan, and Bulgaria have been identified. Based on the empirical data obtained and their comparison with the results of an analytical review of scientific literature, a generalized universal model of the system of universities' scientific and scientific-technical activities has been created, which will optimize the reform process and contribute to the development of research potential.
Design of a Cryptographic System for Communication Security using Chaotic Signals

Disturbance or corresponding errors of the transmission of information affect the ability of error detection. The chaotic encryption system prevents errors and secures the transmission system safely. The security assures by updating chaotic signals with the parameters of the chaotic circuits which are frequently changed. The data decipher and the encryption by the chaotic signaling system renews and changes the initial condition of a chaotic electric circuit. When most of the decimal portions are less than the threshold, the transmission is accepted, and all the noninteger numbers are rounded to their nearest integers. The criterion allows the error-detection function in the security system that is proposed in this paper. The chaotic encryption system for information is applied to public channels by the authorized individual. Three pictorial examples transmitted in the proposed system successfully demonstrate the security and performance. The new system provides high efficiency in the satellite communication network.
Signature GOA: A novel comfort zone parameter adjustment using fuzzy signature for task scheduling in cloud environment

Task scheduling in cloud computing plays an essential role for service provider to enhance its quality of service. Grasshopper Optimization Algorithm (GOA) is an evolutionary computation technique developed by emulating the swarming behavior of grasshoppers while searching for food. GOA is easy to implement but it cannot make full utilization of every iteration, and there is a risk of falling into the local optimal. This paper proposes a suitable approach for adjusting the comfort zone parameter based on the fuzzy signatures called signature GOA (SGOA) to balance exploration and exploitation. Then, we propose task scheduling based on SGOA by considering different objectives such as completion time, delay, and the load balancing on the machines. Finally, different algorithms such as Particle Swarm Optimization (PSO), Simulated Annealing (SA), Tabu Search (TS), and multi-objective genetic algorithm, are used for comparison. The results show that among all algorithms, SGOA can be successful in much less iteration.
DIGITAL PEDAGOGICAL COMPETENCIES OF PHYSICAL EDUCATION TEACHERS

The global COVID-19 pandemic has changed the education system. The use of modern information technologies in the educational process and the introduction of distance learning are becoming more and more relevant. These requirements began to apply to academic disciplines, which a priori are difficult to teach online, in a quarantine situation. Physical education is such a discipline. Requirements for teachers are increasing. The teacher must have digital pedagogical competencies in order to successfully teach this academic discipline in modern conditions. The purpose of this pilot study was to determine the level of formation of digital pedagogical competencies among physical education teachers working in institutions of higher and secondary vocational education. The research is based on the European model Digital Competence of Educators (DIGCOMPEDU). A questionnaire for identifying the formation of digital pedagogical competencies was developed on the basis of this model and tested in this study. Teachers were asked to assess, on a 5-point scale, the level of skills and experience in the application of information technologies in the educational process and in the organization of distance learning, as well as to provide specific resources with which they work.44 teachers of physical education from Pskov State University, College of Pskov State University and Velikie Luki State Academy of Physical Culture and Sports took part in this study. It was found that most of all physical culture teachers have formed the ability to work with search engines and knowledge in the field of information security. The skills to produce and use video and graphics content are the least developed. Also an important problem is the lack of experience in the implementation of distance learning among physical education teachers.Groups of teachers with different levels of formation of digital pedagogical competencies were identified using cluster analysis. Five such levels have been identified.The conducted research determines the problem that physical education teachers lack competence in the field of information technologies and their implementation in the educational process even with a mixed form of education (full-time form with elements of distance learning).

Differentially private density estimation with skew-normal mixtures model

Abstract The protection of private data is a hot research issue in the era of big data. Differential privacy is a strong privacy guarantees in data analysis. In this paper, we propose DP-MSNM, a parametric density estimation algorithm using multivariate skew-normal mixtures (MSNM) model to differential privacy. MSNM can solve the asymmetric problem of data sets, and it is could approximate any distribution through expectation–maximization (EM) algorithm. In this model, we add two extra steps on the estimated parameters in the M step of each iteration. The first step is adding calibrated noise to the estimated parameters based on Laplacian mechanism. The second step is post-processes those noisy parameters to ensure their intrinsic characteristics based on the theory of vector normalize and positive semi definition matrix. Extensive experiments using both real data sets evaluate the performance of DP-MSNM, and demonstrate that the proposed method outperforms DPGMM.
Analysis of Rasch Model for the Validation of Chemistry National Exam Instruments

Information about score obtained from a test is often interpreted as an indicator of the student's ability level. This is one of the weaknesses of classical analysis that are unable to provide meaningful and fair information. The acquisition of the same score if it comes from a test item with a different level of difficulty, must show different abilities. Analysis of the Rasch model will overcome this weakness. The purpose of this study was to analyze the quality of the items by validating the national chemistry exam instrument using the Rasch model. The research sample was 212 new students of the Department of Chemistry at the State University of Medan. The data collected was in the form of respondent's answer data to the 2013 chemistry UN questions, which amounted to 40 items multiple choice and uses the documentation method. Data analysis technique used the Rasch Model with Ministep software. The results of the analysis show the quality of the Chemistry National Exam (UN) questions is categorized as very good based on the following aspects: unidimension, item fit test, person map item, difficulty test level, person and item reliability. There is one item found to be gender bias, in which men benefit more than women. The average chemistry ability of respondents is above the average level of difficulty of the test items
