Authors: Chanamallu Mohana Rao , Saheb K. Meera
Published: August 2020

Metal Matrix Composite (MMC) reinforced in friction stir processing (FSP) has increased insights that can affectively attain the desired mechanical properties for the manufactured samples. The favorable conditions of carbides are considered for reinforcing the SiC particles into the Aluminum 6061. The methodology of fabricating Aluminum 6061 comprises of three materials, Al 6061-SiC-Al2O3. The experimental evaluation of the composite Aluminum 6061-SiC-Al2O3 includes the influence of process parameters on microhardness, tensile strength, and microstructure. As a result of the reinforcement of nanoparticles processed in FSP, the properties of composite material increased satisfactorily. The sample S3 observed to be having a maximum tensile strength of 185 MPa. The larger, the better condition is adopted to analyze the tensile strength of the fabricated samples. The optimum condition for maximum tensile strength was found at 900 RPM, 15 mm/min, and composition 3. The hardness profiles at different zones of friction stir processing (FSP), viz., Heat Affected Zone (HAZ), Thermo Mechanical Affected Zone (TMAZ), Nugget Zone (NZ) were examined. The characterization techniques deployed were optical microscope (OM), and scanning electron microscope (SEM) studies for microstructural behavior. The result shows that the reinforcements were tightly embedded into the base material surface. The spherical grains are formed in the reinforcement region.
THE THE LEVEL OF KNOWLEDGE AND ATTITUDES OF PHARMACY STUDENTS TOWARDS CORTIOSTEROIDS USES
Authors: Julianti Tri Budi
Published: August 2020

Corticosteroids are hormones that naturally produced by the human body through the adrenal gland. Cortisone hormones play a role in regulating blood sugar, protein, fat, the body's defense system and bone formation. Corticosteroid drugs are commonly used for anti-inflammatory, pruritic, dermatological, rheumatologic, pulmonary, hematological, ophthalmological, immunological, and gastrointestinal, called glucocorticoids. Long-term therapy with corticosteroids can cause severe side effects if given in high doses. The aim of this study was identification of the level of knowledge and attitude in corticosteroid use, especially in pharmacy students. This type of research was cross-sectional which aims to see the relationship between the dependent variable and the independent variable in Samarinda. This research was conducted in 2019 by conducting a questionnaire survey test using Google Form. Data analysis in the form of bivariate analysis using the Mann-Whitney test with SPSS Statistic 23 software program. Respondents who participated in this research amounted to 118 people with ages ranging from 17 to 25 years. In this research shows that pharmacy students have a fairly good knowledge of corticosteroids with the majority of the percentage of correct answers ≥72%. The results of the analysis obtained p value 0.008 (p <0.005) and obtained r value 2.7. There is a significant influence between knowledge of corticosteroids on their attitude using corticosteroids and showing good knowledge has the potential of 2.7 times to have a good attitude.
THE EFFECTS OF THE AUTHORITARIAN PARENTING TOWARD STRESS AND SELF-ESTEEM OF TEENS
Authors: Fitriani Dwi Rahmah
Published: August 2020

Adolescence is a period of development and a period of adjustment for adult life and a period of stress and stress is a time of turmoil and pressure. At this time, there was a shift in the role of peers who began to "shift" the role of parents. Parents have an impact on adolescent development through the application of authoritarian parenting that is rigid and strict when interacting with adolescents and not infrequently can create tension in the relation of adolescents with parents so that it can provide psychological effects indirectly. Purpose of the study: This study aimed to determine the relation of authoritarian parenting parents with stress levels and adolescent self-esteem. Research methods:: The method used in this study is a correlation with independent variables parenting and self-dependent variable in adolescents. The population in this study were adolescents in vocational high school as many as 218 respondents with a total sample of 141 respondents taken by stratified random sampling technique. The instrument in this study used the Depression Anxiety Stress Scale questionnaire and Rosenberg Self Esteem and for authoritarian parenting, the writer modified the questionnaire then validity test was conducted. The data was then analyzed using the Spearman correlation test. Results: Showing that authoritarian parenting parents with stress levels have a relation with the results of the spearman correlation test rs = 0.002 and for authoritarian parenting parents and self-esteem there is no relation with the results of the Spearman rho correlation test = 0.139. Conclusion: There is a correlation between the authoritarian parenting style of parents and stress levels can be interpreted that parents who apply the type of authoritarian parenting to their teenagers tend to experience stress from mild to severe. There is no relation between parental parenting and adolescent self-esteem. Can be interpreted that the application of authoritarian parenting from parents in adolescents is not related to adolescent self-esteem. Suggestion: Provide positive support to adolescents to prevent adolescents from experiencing stress, and not limit every activity that teens like so that teens can socialize with their environment.

Published: August 2020

Non-communicable diseases have become a major public health problem in the last decade. In Indonesia, it was more than 36 million people dying from non-communicable diseases related to several risk factors including behavioral, metabolic and social risk factors. Several indicators can be considered to detect the risk factors of non-communicable diseases. They are blood pressure, cholesterol, glucose, uric acid, and body mass index. Efforts to prevent and control non-communicable diseases that are being developed in Indonesia are integrated management posts for non-communicable diseases that provide facilities and guidance to the community to take part in controlling the risk factors for non-communicable diseases. This research is an observational analytic study with the cross-sectional method based on data obtained from the monitoring book of members of the Medical School of Mulawarman University. The sample of this study was all individuals in the population that met the inclusion criteria of the study. Sixty-five samples were obtained to see the posbindu effect on blood pressure and 61 samples saw the effect of posbindu on total cholesterol levels that met the inclusion criteria. The variables observed in this study were posbindu utilization, sample blood pressure, and total cholesterol levels in the sample. The results of the research, there was the effect of using posbindu on sample blood pressure (p = 0.042), and there was no effect on the use of total cholesterol level in the sample (p = 0.590).

Published: August 2020

It has become increasingly clear that COVID-19 transmits between individuals. It stands to reason that the spread of the virus depends on sociocultural ecologies that facilitate or inhibit social contact. In particular, the community-level tendency to engage with strangers and freely choose friends, called relational mobility (RM), entails increased opportunities to interact with a larger and more variable range of others. It may therefore be associated with a faster spread of infectious diseases, including COVID-19. Here, we tested this possibility by analyzing growth curves of confirmed cases and deaths of COVID-19 in the first 30 days of the outbreaks in 39 countries. We found the growth was significantly accelerated as a function of a country-wise measure of RM. This relationship was robust either with or without a set of control variables, including demographic variables, reporting bias, testing availability, and cultural dimensions of individualism and government efficiency. Policy implications are discussed.

Published: August 2020

Data-driven approaches to programming language design are uncommon. Despite the availability of large code repositories, distilling semantically-rich information from programs remains difficult. Important dimensions, like run-time type data, are inscrutable without the appropriate tools. We contribute a task abstraction and interactive visualization, TYPEical, for programming language designers who are exploring and analyzing type information from execution traces. Our approach aids user understanding of function type signatures across many executions. Insights derived from our visualization are aimed at informing language design decisions — specifically of a new gradual type system being developed for the R programming language.

Orbitofrontal Cortex Grey Matter Volume is Related to Children's Depressive Symptoms
Authors: Vandermeer Matthew Richard John , Liu Pan , Ali Ola Mohamed , Daoust Andrew , Joanisse Marc F , Barch Deanna , Hayden Elizabeth P.
Published: August 2020

Adults with a history of depression show distinct patterns of grey matter volume (GMV) in frontal cortical (e.g., prefrontal cortex, orbitofrontal cortex) and limbic (e.g., anterior cingulate, amygdala, hippocampus, dorsal striatum) structures, regions relevant to the processing and regulation of reward, which is impaired in the context of depression. However, it is unclear whether these GMV associations with depression precede depressive disorder onset or whether GMV is related to early emerging symptoms or familial depression. To address these questions, we used voxel-based morphometry (VBM) to examine GMV in 85 community-dwelling children (M = 11.12 years, SD = .63 years) screened for current and lifetime depression. Associations between children’s depressive symptoms (self- and mother-report of children’s symptoms), children’s maternal depression history, and GMV were examined. Although maternal depression history was unrelated to children’s GMV, child GMV in the orbitofrontal cortex (OFC) was negatively related to children’s self-reported depressive symptoms, using both a priori ROI and whole-brain analyses. Moderated regression analyses indicated that girls’ GMV was negatively related to girls’ depressive symptoms (as indexed by both self- and mother-report of girls’ symptoms), whereas boys’ symptoms were positively related to GMV. Our findings suggest that brain morphology in the OFC, a region with functional roles in processes relevant to depressive symptoms (i.e., reward-based learning and reward processing), is associated with early depressive symptoms prior to the development of clinically significant depression.
On unreplicable inferences in psychopathology symptom networks and the importance of unreliable parameter estimates
Authors: Forbes Miriam K. , Wright Aidan G.C. , Markon Kristian Eric , Krueger Robert
Published: August 2020

We recently wrote an article comparing the conclusions that followed from two different approaches to quantifying the reliability and replicability of psychopathology symptom networks. Two commentaries on the article have raised five core criticisms, which are addressed in this response with supporting evidence. 1) We did not over-generalise about the replicability of symptom networks, but rather focused on interpreting the contradictory conclusions of the two sets of methods we examined. 2) We closely followed established recommendations when estimating and interpreting the networks. 3) We also closely followed the relevant tutorials, and used examples interpreted by experts in the field, to interpret the bootnet and NetworkComparisonTest results. 4) It is possible for statistical control to increase reliability, but that does not appear to be the case here. 5) Distinguishing between statistically significant versus substantive differences makes it clear that the differences between the networks affect the inferences we would make about symptom-level relationships (i.e., the basis of the purported utility of symptom networks). Ultimately, there is an important point of agreement between our article and the commentaries: All of these applied examples of cross-sectional symptom networks are demonstrating unreliable parameter estimates. While the commentaries propose that the resulting differences between networks are not genuine or meaningful because they are not statistically significant, we propose that the unreplicable inferences about the symptom-level relationships of interest fundamentally undermine the utility of the symptom networks.
Nonsuicidal self-injury thoughts and behavioural characteristics: Associations with suicidal thoughts and behaviours among community adolescents
Authors: Robinson Kealagh , Garisch Jessica A. , Wilson Marc
Published: August 2020

Background: We consider whether nonsuicidal self-injury (NSSI) thoughts – in the absence of any NSSI behaviour – are associated with suicidal thoughts and behaviours among adolescents, before examining whether characteristics of NSSI behaviour are associated with greater suicidal thoughts and behaviours. Methods: Adolescents (n = 2,057, M age =15.56) recruited from secondary schools reported their lifetime history of NSSI, suicidal thoughts and behaviours, NSSI characteristics, and NSSI functions. Receiver Operating Characteristic analysis test whether NSSI status and characteristics of NSSI behaviour are diagnostic of clinically elevated suicidal thoughts and behaviours (a score of 7 or higher on the Suicide Behaviours Questionnaire-Revised). Regression models test whether NSSI functions predict greater suicidality. Results: Adolescents with NSSI thoughts and those with NSSI behaviour were more likely to report lifetime suicidal ideation and past-year suicide plan(s) than adolescents with no history of NSSI. In addition, adolescents with a history of NSSI were more likely to report a lifetime history of suicide attempt(s) as well as past-year suicide attempt(s) than adolescents with no history of NSSI. A greater number of NSSI methods, requiring medical assistance for NSSI injuries, and engaging in NSSI for self-punishment, anti-suicide, and sensation-seeking functions were associated with greater severity of suicidal thoughts and behaviours.Limitations: Data are cross-sectional, limiting inferences about causality.Conclusions: Findings emphasize the importance of NSSI thoughts and characteristics of NSSI behaviour in understanding the complex relationship between NSSI and suicidal thoughts and behaviours among adolescents.
Constraining Cooperation: Military Relations and Government Repression
Authors: D'Orazio Vito
Published: August 2020

Sometimes states repress political campaigns harshly, and sometimes they do not. Why? I argue that military cooperation with liberal democracies constrains the state from using severe forms of repression against opposition campaigns. Liberal democracies face costs for human rights violations by their friends, and are likely to coerce the military from repressive actions. Such interconnectedness also socializes the military with democratic militaries that have strong norms against the use of widespread and excessive repression. However, the military is not the only repressing agency, and therefore this constraint does not act to prevent repression but rather to limit its severity. This theory is tested using the NAVCO data and a new, latent measure of military cooperation. I find that military cooperation with liberal democracies does not prevent the state from repressing opposition movements, but it does limit the severity. This finding provides evidence of one benefit to expanding multinational security cooperation initiatives involving liberal democracies.
Modeling the Evolution of Ideological Landscapes through Opinion Dynamics
Authors: Lorenz Jan
Published: August 2020

This paper explores the possibilities to explain the stylized facts of empirically observed ideological landscapes through the bounded confidence model of opinion dynamics. Empirically, left-right self-placements are often not normally distributed but have multiple peaks (e.g. extreme-left-center-right-extreme). Some stylized facts are extracted from histograms from the European Social Survey. In the bounded confidence model, agents repeatedly adjust their ideological position in their ideological neighborhood. As an extension of the classical model, agents sometimes completely reassesses their opinion depending on their ideological openness and their propensity for reassessment, respectively. Simulations show that this leads to the emergence of clustered ideological landscapes similar to the ones observed empirically. However, not all stylized facts of real world ideological landscapes can be reproduced with the model. Changes in the model parameters show that the ideological landscapes are susceptible to interesting slow and abrupt changes.A long term goal is to integrate models of opinion dynamics into the classical spatial model of electoral competition as a dynamic element taking into account that voters themselves shape the political landscape by adjusting their positions and preferences through interaction.
THE IMPROVEMENT OF STUDENTS’ ACADEMIC WRITING THROUGH READING ABILITY USING COOPERATIVE INTEGRATED READING AND COMPOSITION (CIRC) MODEL
Authors: Aruan Rumiri
Published: August 2020

This learning improvement study aims to improve teaching and learning outcomes in academic writing through reading ability by applying CIRC model. This research was conducted based on the problems that occur when students taking Academic Reading and Writing courses. Among the problems found is that students still find difficulties in writing a summary of the specified article. The research subjects were students in the fourth semester of the academic year 2018/2019. Before applying this method, the writer conducted a pre-test. The pre-test results showed that the students' writing summary skills were still low. The pre-test result was 2.77% of students scored very well, 19.43% got a good score, 27.77% of students scored moderately, 47.22% scored less, and 2.77% in the category of failure. The Classroom Action Research method is carried out in the application of the CIRC model which consists of two cycles, where each cycle took place in two meetings, and each cycle applied different learning activities. The results of the first cycle have shown changes in several assessment criteria, but the research was still being carried out into the second cycle. This was done to further strengthen learning by using the CIRC model. The percentage of student scores in the second cycle shows that 36.03% got a very good score, 33.33% got a good score, 30.55% got a sufficient score, and no more students scored less, and failed. From the above results can be concluded that the application of the CIRC model by the distribution of different discussion groups in each cycle affected learning outcomes. Thus the CIRC model can be considered to use in learning academic writing through reading ability in Academic Reading and Writing courses.
Advanced training peculiarities of physical education teachers in quarantine terms
Authors: Bielikova N.
Published: August 2020

The global pandemic and forced self-isolation have become significant factors in the rapid restructuring of training at all levels of education, and postgraduate in particular. They have caused not only the reformatting of the content, forms and methods of the advanced training system, but also mastering of tools and technologies of distance learning as the main way of communication between the educational process subjects. The article analyzes the contemporary tendencies in organization of the advanced training process of physical education teachers based on introduction of distance learning technologies. Improving the advanced training system of physical education teachers comprises the use of their multilevel preparation, which consists of continuous self-educational activity (first level); regular participation in organized forms of advanced training (advanced training and internship courses) (second level); analytical, scientific, and practical activity (third level). Self-educational activity includes acquaintance with online tools for distance learning organization and their use in practice. «Methodical materials» prepared by the Committee of Physical Education and Sports of the Ministry of Education and Science of Ukraine for physical education teachers, the implementation purpose of which is to diversify motor leisure in quarantine terms; informational content of the YouTube channel «Junior Z» in the framework of the All- Ukrainian project «Physical Culture of the Future»; the project of the Ministry of Digital Transformation of Ukraine «Digital Physical Education for schoolchildren with the participation of sports stars» are among them. The example of organized form of advanced training of physical education teachers is given based on the experience of Lesya Ukrainka Eastern European National University in the sphere of postgraduate education and continuous pedagogical education. In particular, the curriculum and organization peculiarities of the distance advanced training course for physical education teachers in quarantine terms are characterized. By conducting distance learning courses in such a way, teachers' behavior is modelled when they need to organize distance learning support for students in their schools. Within the framework of continuous education, physical education teachers should improve their qualification not only in their professional specialization field, but also in the sphere of information and communication technologies.

Authors: Demchenko V. , Zhadan A. , Khudyakova V.
Published: August 2020

Purpose: to reveal the features of the use of tactical actions by boxers of highly qualified women. Materials and methods: Theoretical analysis of information from the scientific and methodological literature and communication with the leading trainers of women in boxing made it possible to analyze the history of the development of women's boxing in the World, to determine the importance of tactical training for boxers and its content. Also during this research, we watched videos of the competitive activity of highly qualified female boxers in weight categories up to 51 kg. and up to 75 kg. Using the methods of pedagogical observation, chronometric observation and mathematical statistics made it possible to identify the peculiarities of tactics of competitive battle tactics in women boxers of high qualification. Results: At the present stage of the development of women's boxing, the world leader is the Russian team, the second is China, the third is India. Ukraine is not one of the top ten women's boxing teams in the World. Tactical training in women's boxing should be significantly different from the tactical training of male boxers. Women boxers of high qualification of lightweights can be related to tempo men, and women boxers of high qualification of heavyweights to gamers. However, it is difficult to related some women boxers of high qualification to any one of the listed types, since they are able to rearrange tactics during the match itself, if necessary. Conclusions: Modern tactical training in women's boxing is aimed at universalization, which is characterized by a variety of applied techniques and their frequent change. This fact makes increased demands on the quality of the technical training process in women's boxing.

Published: August 2020

The article deals with problematic issues of the attitude of student youth to health-forming components during their studies in higher education institutions. Also the estimation of reasons of occurrence of the inadequate relation to components which have direct influence on a health condition and their consequences was carried out.

This assessment of the system of physical education since the independence of Ukraine, which was in a deep state of crisis and could not meet the needs of young people in motor activity and physical fitness. This has dealt an irreparable blow to the motivational-value attitude to the health-forming of the constituents and to the health of students.

Thanks to pedagogical observation, pedagogical testing, extrapolations and the results of mathematical statistics, the majority of students of the higher education institutions have systematically missed physical education classes because of the lack of interest and desire for traditional physical education classes, laziness, unsatisfactory conditions of classes, lack of sports sections that interest students, which proves the insufficient level of motivation and value attitude of students to physical education classes.

The assessment of students physical development and functional condition showed that their body weight, HR have a tendency to worsen. The level of physical fitness indicates that students have a low and lower average level of physical education in the I and II courses.

So, the current system of physical education does not provide enough effective development and improvement of physical qualities of students, indicates the need to improve it in order to improve health, improve mental and physical performance, the formation of motivation for systematic exercise and a positive attitude to health-forming components through the introduction of physical education classes with sports orientation, taking into account the free choice of students.

According to the authors, the assessment of the functional state of the cardiorespiratory system of the body during physical training and sports is of paramount importance because of the huge role of this system in the adaptation to physical activity of different nature, the optimal functioning of the organism in the most varied in terms of training activity.

The analysis of the scientific literature shows that the deterioration of the indicators of the functional state of the cardiorespiratory system of the human body caused by the weakening of socio-economic conditions in the country, the influence of radioactive radiation, the deterioration of the quality of nutrition, the decrease of motor activity, etc. There is also a general increase in the number of cardiovascular diseases, deterioration of the body's functional reserves, systemic impaired posture, the presence of various disorders of the musculoskeletal system, a decrease in the level of physical fitness, etc.

All this happens against the background of the weakening of the functions of the cardio-respiratory and nervous systems of the body during training and during the exams, which negatively affects the formation of health of future specialists. Therefore, since there is a tendency to deteriorate the health of students, in particular, the condition of their cardio-respiratory system, the question of improving it through the use of physical education is very relevant.

Ukraine carries out a wide range of measures that create the necessary conditions for work and life, improvement of the external, including industrial, environment, further development of health care. At the same time, human activity by means of physical culture and sports are important factors in improving and strengthening health, which ultimately increases a person's creative activity, his ability to work. Aim of the research - to determine experimentally the effectiveness of the application of aerobics on the psychophysiological state and the special ability of women of the teaching staff. The following research methods were used to achieve the goal: analysis, generalization, systematization of literature sources on the problem of research, questionnaires, surveys, psychophysiological research methods, pedagogical research methods. Results of the research: exercise in classical aerobics contributes to the activation of various structures of the CNS, as a result of which women began to respond more quickly to light signals. Special working capacity increased by 48.5%. Having completed the study of strength aerobics classes in women, there was a significant increase in the potential of cardiohemodynamics. Training complexes of physical exercises in aerobics with the use of various equipment, lead to the activation of different parts of the cerebral cortex, which is expressed in a reduction (approximately 15%) of the visual-motor reaction time, increases (approximately 14.5%) special performance. Under the influence of training on strength training equipment in women, the potential of cardiohemodynamics decreases, and on the other hand, as a result of activation of the cortical structures of the brain, professional efficiency increases. Conclusions. Systematic physical culture and sports normalize the work of almost all organs and systems of the body, increase the psycho-emotional state, physical and mental activity.

It is important to determine what opportunities exist in the processes of acquisition, preservation and realization of value constellations, relative to another person in the boarding school environment compared to other educational institutions regarding the use of the most important existential of practical life. Teachers pay attention to a number of factors that prevent the effective education of value attitude towards the person. There are crime, anger, sense of permissibility, low level of personal communication, irresponsible, life pessimism and etc. among them. Analysis of theoretical works and synthesis of scientific provisions suggest that value attitude towards another person is an integrated neoplasm, which is determined by humanistic ethics and morality and is based on moral values such as respect, dignity, equality, benevolence, balance, self-sufficiency, readiness for constructive dialogue. Therefore, the formation of the value of another person is a specially organized educational process, which defines the attitude towards another person, as the highest value of the subject of life, aimed at combining knowledge about such moral values as respect for dignity, equality, benevolence, balance, self-sufficiency, readiness for constructive dialogue, ideas about the ways of their manifestation and ability to guide them in their own activities. Thus, philosophical, psychological and pedagogical studies show that the value attitude towards another person is an important characteristic of the moral sphere of the individual and is most confirmed by humanistic ethics and morality and is the basis of domestic and international legislation, which needs the close attention and development of optimal pedagogical conditions for the formation of a value attitude towards another person in pupils of boarding schools, as the most impressionable category of children with a view to their socialization and full integration into society.
APPLICATION OF THE BIOMASS PYROLISIS PRODUCTS AS A REBURNING FUEL FOR NITROGEN OXIDES REDUCTION: TESTING THE CHEMICAL KINETICS MECHANISM
Authors: Kobzar S.G. , Khalatov A.A.
Published: August 2020

The mechanisms of chemical kinetics of the Reburning process using pyrolysis gases as a reburn fuel are determined. It has been shown that CO, CO2, H2 have very little effect on the reduction of the nitrogen oxides under conditions characteristic for the coal combustion, and hydrocarbons play the major contribution to the reduction of the nitrogen oxides. The results of the test calculations showed that the process of the nitrogen oxides reduction by the biomass pyrolysis products can be calculated by a simplified mechanism of the chemical kinetics of the Reburning process by replacing hydrocarbons with one substance (with a close carbon/hydrogen ratio as in the real pyrolysis gas mixture), provided that the mass fraction of carbon is preserved, fed to the reduction of nitrogen oxides unchanged. This approach significantly reduces machine time and calculates the nitrogen oxides reducing efficiency by Reburning technology with an accuracy of 17%.

The necessity of developing a policy of adaptation to global warming, in particular in the public utilities sector, was highlighted. A brief review of organizational, economic, and technological innovations of energy-efficient use of energy resources with a reduction in emissions of harmful emissions and greenhouse gases is presented. The goal is formulated and the main components of the strategy for adapting municipal energy to global warming are indicated.
Theories for incompressible rods: A rigorous derivation via Γ-convergence
Authors: Engl Dominik , Kreisbeck Carolin
Published: August 2020

We use variational convergence to derive a hierarchy of one-dimensional rod theories, starting out from three-dimensional models in nonlinear elasticity subject to local volume-preservation. The densities of the resulting Γ-limits are determined by minimization problems with a trace constraint that arises from the linearization of the determinant condition of incompressibility. While the proofs of the lower bounds rely on suitable constraint regularization, the upper bounds require a careful, explicit construction of locally volume-preserving recovery sequences. After decoupling the cross-section variables with the help of divergence-free extensions, we apply an inner perturbation argument to enforce the desired non-convex determinant constraint. To illustrate our findings, we discuss the special case of isotropic materials.
Boosting the classification performance of latent fingerprint segmentation using cascade of classifiers
Authors: Chhabra Megha , Shukla Manoj Kumar , Ravulakollu Kiran Kumar
Published: August 2020

Segmentation and classification of latent fingerprints is a young challenging area of research. Latent fingerprints are unintentional fingermarks. These marks are ridge patterns left at crime scenes, lifted with latent or unclear view of fingermarks, making it difficult to find the guilty party. The segmentation of lifted images of such finger impressions comes with some unique challenges in domain such as poor quality images, incomplete ridge patterns, overlapping prints etc. The classification of poorly acquired data can be improved with image pre-processing, feeding all or optimal set of features extracted to suitable classifiers etc. Our classification system proposes two main steps. First, various effective extracted features are compartmentalised into maximal independent sets with high correlation value, Second, conventional supervised technique based binary classifiers are combined into a cascade/stack of classifiers. These classifiers are fed with all or optimal feature set(s) for binary classification of fingermarks as ridge patterns from non-ridge background. The experimentation shows improvement in accuracy rate on IIIT-D database with supervised algorithms.
Comparative analysis of evolutionary algorithms for multiple criteria decision making with interval-valued belief distributions

In multiple criteria decision making (MCDM) with interval-valued belief distributions (IVBDs), individual IVBDs on multiple criteria are combined explicitly or implicitly to generate the expected utilities of alternatives, which can be used to make decisions with the aid of decision rules. To analyze an MCDM problem with a large number of criteria and grades used to profile IVBDs, effective algorithms are required to find the solutions to the optimization models within a large feasible region. An important issue is to identify an algorithm suitable for finding accurate solutions within a limited or acceptable time. To address this issue, four representative evolutionary algorithms, including genetic algorithm, differential evolution algorithm, particle swarm optimization algorithm, and gravitational search algorithm, are selected to combine individual IVBDs of alternatives and generate the minimum and maximum expected utilities of alternatives. By performing experiments with different numbers of criteria and grades, a comparative analysis of the four algorithms is provided with the aid of two indicators: accuracy and efficiency. Experimental results indicate that particle swarm optimization algorithm is the best among the four algorithms for combining individual IVBDs and generating the minimum and maximum expected utilities of alternatives.

Cloud Computing is widespread to support industrial and academy related applications worldwide. The archival data process in the cloud is one of the challenging tasks. To handle this issue, the authors addressed the model, which allows authenticating the cloud storage using the JOSS (Java Library for Open stack storage) through the authentication URL. To achieve the authentication of the heterogeneous data while uploading into the cloud storage, a proposed model developed using the JOSS. To address this research question and demonstrate our approach, we have created the API for the archival solution in order to authenticate the cloud storage using the JOSS authentication model, providing the authentication URL. It consists of the user id and password for the verification of the user while transmitting the data into the cloud storage. The API is becoming dynamic and complex, and one of the major challenges faced by the developer in order to develop appropriate standalone applicataion interface. The extensible mechanism for authentication requires a URL in order to connect to the cloud storage system. The objective of this paper is to enhance/optimize the rate of transmission to upload the data in the cloud storage using the rclone.

The lack of physical contact and the demanding need for personalized services has prompted stakeholders in distance learning to benefit from the enormous volume of students’ online traces in the Learning Management Systems. Data mining methodologies are widely applied to analyze data logs and predict trends for early and efficient interventions. Thus, the retention of students in the educational process can be achieved with positive effects on the reputation and finances of the institutions. This work divides the moodle data sets from six different sections of an annual postgraduate program at the Hellenic Open University in six periods for each section, due to the number of written assignments. Then it implements data mining techniques to analyze the activity, polarity and emotions of tutors and students in order to predict students’ grades. The results indicate the algorithm with the highest precision in each prediction. In addition, the research concludes that polarity and emotions as independent variables provide better performance in comparative models. Moreover, tutors’ variables are highlighted as an important factor for more accurate predictions of student grades. Finally, a comparison of actual and predicted grades indicates which students have used a third party to fulfill their assignments.

In this paper, the concept of body of revolution (BOR) finite-difference time-domain method time-domain (BOR-FDTD) method is applied to symplectic multi-resolution time-domain (SMRTD) algorithm to propose a BOR-SMRTD method. In order to solve the problem that the obliquely incident pulse wave cannot be directly introduced into BOR-SMRTD method, an efficient one-dimensional time-domain algorithm for propagating obliquely incident pulse plane wave in BOR-SMRTD method is also proposed. The numerical results show that the proposed algorithm runs 51 times faster than the algorithm based on fast Fourier transform (FFT) completely. Moreover, the scattering problem of a perfect electric conductor (PEC) cylinder with finite length is calculated to verify the effectiveness of the algorithm. The surface current density distribution along a generatrix of the cylinder at a giving frequency was extracted, and the results are in good agreement with that obtained with the methods of moment (MoM) and BOR-FDTD. Finally, the radar cross section (RCS) of a PEC sphere was calculated, and the results agree well with the theoretical values.
