Linear Regression Algorithm in Machine Learning through MATLAB

In the present scenario, it is quite aware that almost every field is moving into machine based automation right from fundamentals to master level systems. Among them, Machine Learning (ML) is one of the important tool which is most similar to Artificial Intelligence (AI) by allowing some well known data or past experience in order to improve automatically or estimate the behavior or status of the given data through various algorithms. Modeling a system or data through Machine Learning is important and advantageous as it helps in the development of later and newer versions. Today most of the information technology giants such as Facebook, Uber, Google maps made Machine learning as a critical part of their ongoing operations for the better view of users. In this paper, various available algorithms in ML is given briefly and out of all the existing different algorithms, Linear Regression algorithm is used to predict a new set of values by taking older data as reference. However, a detailed predicted model is discussed clearly by building a code with the help of Machine Learning and Deep Learning tool in MATLAB/ SIMULINK.

Design, Development and Use of a Digital Badges System in Higher Education

Badges are non fungible tokens used to document or certify achievements in academics or in any other domain. Besides their utility as proof of achievement, badges are of interest in higher education as pure incentives to push the students and learners in general toward pursuing well-defined goals and skills. In this respect, badges can be naturally incorporated into digital learning platforms also as part of informal learning activities, and stimulate participation, merit, and visibility for the students. However, the level of engagement of learners into these learning activities depends crucially on how the system of badges and rewards has been designed and on how it is applied, if it is to be used effectively. In this paper, we report on the design and implementation of a smart badges system, and an example of its use inside a gamification methodology for informal learning in a master level course, and discuss the benefits and the observed gains in learning performance that can be obtained.

„Pejzaż górski nie odpowiadał mi malarsko”, Zakopiański epizod graficzny Jana Skotnickiego

Abstrakt: W artykule omówiona została graficzna twórczość młodopolskiego malarza Jana Skotnickiego, przypadająca na lata 1909–1914. W 1908 r. artysta wraz z żoną Teodorą z Trenklerów wyjechali z Krakowa do Zakopanego. Pobyt artysty zbiegł się w czasie z intensywnym rozwojem kulturalnym kurortu. W miejscowe inicjatywy Skotnicki angażował się osobiście, przy finansowym wsparciu swego teścia, łódzkiego przemysłowca i kolekcjonera, Henryka Grohmana. Jednocześnie tutejszy krajobraz i popularna w owym czasie góralska sztuka ludowa, zupełnie artysty nie inspirowały, przez co niemal zarzucił malarstwo, a zainteresował się grafiką i kilimiarstwem. Polem nowych zainteresowań stała się otwarta staraniem Grohmana eksperymentalna pracownia wyposażona m.in. w prasy drukarskie. W kolejnych latach Skotnicki prezentował swoje ryciny na licznych wystawach, także tych towarzyszących organizowanym konkursom graficznym (1911, 1914), a po wyjeździe do Warszawy (1912) przyłączył się do Towarzystwa Przyjaciół Sztuk Graficznych. Skotnicki uprawiał techniki metalowe, bardzo szybko osiągając w nich wysoki poziom zauważony przez krytyków. Łączył akwafortę, akwatintę, suchą igłę i ruletkę, eksperymentował z drukiem barwnym i kolorował odbitki, mocno indywidualizował prace podczas ich odbijania, stosując tintę. Jego dorobek graficzny oszacowany zastał na ponad 50 kompozycji, przy czym w kolekcjach publicznych znajduje się ich obecnie przynajmniej 36. Są to pejzaże, widoki miasteczek i architektury, akty, studia postaci i zwierząt, w wielu przypadkach wzorowane na własnych szkicach i obrazach. Tematycznie i kompozycyjnie wykazują one wiele podobieństw do prac twórców młodopolskich, zarówno z grona profesorów (J. Stanisławski), jak i rówieśników podejmujących próby graficzne (W. Skoczylas). W sposobie budowania kompozycji, kadrowania, asymetrii i fragmentaryczności przedstawień widoczne są wpływy sztuki japońskiej, stanowiącej ważne źródło inspiracji za sprawą kolekcji i działalności Feliksa „Mangghi” Jasieńskiego. Znacząca była również kolekcja Grohmana, za pośrednictwem której Skotnicki mógł poznać twórczość XIX-wiecznych odnowicieli sztuk graficznych, jak i artystów kolejnych pokoleń (J.M. Whistler, F. Rops, E. Carrière), co znalazło odbicie w jego rycinach. Nieco zapomniana działalność Skotnickiego wpisuje się w ogólniejszą tendencję: zainteresowania młodopolskich artystów sztukami graficznymi i zaangażowania na rzecz ich popularyzacji na przełomie XIX i XX w. Jest przykładem poszukiwania własnego języka wypowiedzi w nowym medium, samodzielnie podejmowanego eksperymentu. Choć Skotnicki nie był pionierem sztuk graficznych na ziemiach polskich, to z pewnością stał się ich propagatorem. Summary: The article discusses the graphic output of Jan Skotnicki, a painter of Young Poland, which he created in the years 1909–1914. In 1908, the artist and his wife, Teodora née Trenkler, left Cracow for Zakopane. The artist’s stay there coincided with the intensive cultural development of the resort. Skotnicki was personally involved in local initiatives, with the financial support of his father-in-law, an industrialist and art collector from Łódź, Henryk Grohman. However, the local landscape and the highland folk art popular at that time did not suit him at all. As a result, he nearly gave up painting and became interested in prints and kilims. An experimental studio, opened thanks to Grohman’s efforts, became Skotnicki’s new field of interests. It was equipped with, among other things, printing presses. In the following years, Skotnicki presented his prints at numerous exhibitions, including those accompanying print competitions (in 1911 and 1914), and after moving to Warsaw (in 1912), he joined the Society of Friends of Graphic Arts. Skotnicki used metal techniques and quickly achieved a master level, which was noticed by critics. He combined etching, aquatints, drypoints and roulette, experimented with colour printing and coloured prints. He strongly individualised his works while creating prints by using tint. His graphic output was estimated at more than 50 compositions, with at least 36 currently in public collections. They include landscapes, views of towns and architecture, nudes, studies of figures and animals, which in many cases were modelled on his own sketches and paintings. In terms of themes and composition, they show many similarities to the works of Young Poland artists from the group of professors (J. Stanisławski) as well as peers undertaking graphic attempts (W. Skoczylas). The way of building the composition, framing, asymmetry and fragmentation of the representations reveal the influence of Japanese art, which was an important source of inspiration thanks to the collection and activity of Feliks "Manggha" Jasieński. Grohman’s collection was also significant, as Skotnicki could learn from it about the works of 19th-century restorers of graphic arts, as well as about the artists of subsequent generations (J. M. Whistler, F. Rops, E. Carrière), which was reflected in his prints. The somewhat forgotten activity of Skotnicki was part of a more general trend: the interest of Young Poland artists in graphic arts and their involvement in their popularisation at the turn of the 19th and 20th centuries. His output is an example of searching for one’s own language of expression in a new medium, and an experiment he performed independently. Although Skotnicki was not a pioneer of graphic arts in Poland, he certainly became their promoter.

The role of education on the enhancement of heritage awareness and sustainability of the built environment; learning from experts and students

This paper presents the outcomes of Intellectual Output 2 (IO2) of the HERSUS research project. The scope of the survey was to create an argumentative and critically analysed report on the state of learning of sustainability and heritage in higher education. The study is based on the dissemination of two online questionnaires within the five HERSUS participating countries/institutions (Serbia, Italy, Cyprus, Greece and Spain). The first addresses experts in the fields of cultural heritage conservation and sustainable environmental design, occupied in academia, public administration, NGOs and the private sector. The second directs queries to students at master level studies, PhD researchers and recent alumni from academic institutions, in the five participating countries, regarding their experience from their study programs, their expectations and future prospects in the professional environment. The survey analysis was conducted independently for each country and comparisons derive from the review of the international summed outcome. The results of the survey conducted in Greece, are discussed here, reflecting the views of 10 experts and 120 students. The analysis reveals comparable results among responses, with similarity and variation between the views of experts and students. Common ground between the two groups of respondents is found for the establishment of further links between academic education and professional practice, interdisciplinarity in education, and the need for a more systematic correlation between concepts of sustainability and heritage.

Background: Among the non-communicable diseases diabetes is life-threatening condition whose long-time complication causes heart attack, blindness, stroke and kidney failure. The objective was to determine the knowledge, attitude and practice regarding diabetes among the final year students of home economics, university of Peshawar. Methods: This was a descriptive cross-sectional study carried out among final year university students of home economics, university of Peshawar from June to December 2019. Non-probability convenient sampling technique was used for the study. After taking written consent from individual participants a predesigned questionnaire was filled. Data was collected and analyzed by using SPSS version 16. Results: This study included a total of 120 female students of graduate and master level. Among these students 33 (27.5%) were undergraduate and 87 (72.5%) were master level students. It was found that 39 (32.5%) female students were either self-diabetics or one or more close blood related family member were suffering from diabetes. A significantly high proportion 59 (49.2%) and 15 (12.5%) female students were either overweight or obese respectively. About 59 (49.2%) students were with unsatisfactory diabetics practice score, 73 (60.8%) students never checked for sugar and 7 (5.8%) students were found with other chronic diseases status. Interestingly only 28 (23.3%) students know about diabetes and acquired knowledge about diabetes from nutritionists. Conclusion: The increased frequency of obesity & overweight, unsatisfactory diabetes score, unhealthy behavior and suboptimal attitude of female university students provided a threat of potential increase of diabetes among females in future.

Teaching Social Determinants of Health as the World Burns Down: Strategies Learned From Teaching in a Pandemic

Social determinants of health (SDOH), or the conditions in which people are born, live, learn, work, and age, influence health behavior and health outcomes. Often, in health education and behavior literature, emphasis is placed on individual behavior. However, scholars are beginning to move more upstream and incorporate SDOH frameworks into public health research. Thus, teaching SDOH is necessary for the next generation of public health scholars. In the COVID-19 pandemic era, SDOH are more prominent than ever as we educate and advocate to increase health equity. We present four strategies on teaching SDOH to master-level candidates in a virtual “Zoom-fatigue” environment during high-profile world events such as the COVID-19 pandemic, racialized police violence, and a contested election.

TECHNOLOGY MAJORS’ METHODOLOGY EDUCATION: COMPARING APPROACHES FROM TWO COURSES

The National Defense University (NDU) trains officers to develop their academic and professional skills. To accomplish this, the university offers two mandatory courses on methodological training for military technology students for master level education. The first course was theoretically oriented, and the second course was practically oriented. These both master-level methodology courses emphasize practice oriented mathematical skills, which officers use in their operative decision-making and statistical analysis. This study focuses on student-centered learning methodologies linked to teachers’ observations from current and previous course implementations. Results in this study described the outcome from the first run of the revised curriculum. We collected data from students’ course reports and the university’s standard student evaluation of teaching (SET). According to the SET, the course 2 which was practically oriented course, where groups worked on more significant projects gained higher value among students. In conclusion, we recommend that teachers continue using student-centered learning methodologies to technical students as much as possible. Theoretically underscored courses should also contain more practical examples. Keywords: distance education, flipped learning, learning by doing, research methodology, student-centered learning

Coupler force reduction method for multiple-unit trains using a new hierarchical control system

During traction and braking of multiple-unit trains, substantial longitudinal dynamic forces might occur in couplers due to the non-optimal distribution of traction and braking forces generated by self-propelled carriages. These dynamic forces might create shocks affecting the reduction of endurance of the weakest train structural components primarily. Thus, the overall operational safety of the train is also lowered. The purpose of the paper is to develop a new control system to supervise the activities related to the longitudinal dynamics of each train carriage in a multiple-unit train to reduce the longitudinal coupler forces acting during train traction and braking. The hierarchical structure of the control system consists of two levels. The first master level of control works like standard cruise control. However, the reduction of longitudinal coupler forces is achieved by applying a second level of slave control systems with a control configuration of feedback compensation.

Рeculiarities of the content of the course «Pedagogical consulting» in student training by master's programs

The content of the article considers the issue of training teachers and heads of educational organizations in the specialties 011 «Educational, pedagogical». Problems of teaching students in these specialties involve obtaining the necessary knowledge and opportunities for professional development.The article draws attention to the study of the concept of consulting services in Ukraine in the field of education. The analysis of research on the concept of «consulting» as an activity, in terms of different approaches, revealed that it plays an important role in the development of educational organizations. Since consulting is based on the scientific organization of labor, systematic analysis, scientifically sound methods of decision making. The focus is on understanding the importance of management consulting, which helps identify which places in the organization are most vulnerable, adjusts the activities of the organization as a whole and in turn, is divided into strategic, marketing and personnel. It is proved that the study of the discipline «Pedagogical Consulting» in the training of the second (master) level should enrich students with knowledge about the possibilities and effectiveness of consulting counseling, psychological and pedagogical audit, skills of consultants-trainers who coordinate activities in small organizations and groups, master the skills to develop programs for innovative development of the team and conduct various types of diagnostics, etc. It is determined that in the process of teaching the discipline the main attention should be paid to the acquisition of professional competencies by students; intensification of educational and cognitive activities of students, which involves the use of both active and interactive learning technologies; the use of certain methods of activating the learning process. A necessary element of successful mastering of the discipline material is independent work of students, and the system of assessment of formed competencies in students, which considers the types of classes stimulates daily systematic work of masters and increases motivation of masters to master management educational programs based on evaluation of their work
