POSIT vs. Floating Point in Implementing IIR Notch Filter by Enhancing Radix-4 Modified Booth Multiplier

The increased demand for better accuracy and precision and wider data size has strained current the floating point system and motivated the development of the POSIT system. The POSIT system supports flexible formats and tapered precision and provides equivalent accuracy with fewer bits. This paper examines the POSIT and floating point systems, comparing the performance of 32-bit POSIT and 32-bit floating point systems using IIR notch filter implementation. Given that the bulk of the calculations in the filter are multiplication operations, an Enhanced Radix-4 Modified Booth Multiplier (ERMBM) is implemented to increase the calculation speed and efficiency. ERMBM enhances area, speed, power, and energy compared to the POSIT regular multiplier by 26.80%, 51.97%, 0.54%, and 52.22%, respectively, without affecting the accuracy. Moreover, the Taylor series technique is adopted to implement the division operation along with cosine arithmetic unit for POSIT numbers. After comparing POSIT with floating point, the accuracy of POSIT is 92.31%, which is better than floating point’s accuracy of 23.08%. Moreover, POSIT reduces area by 21.77% while increasing the delay. However, when the ERMBM is utilized instead of the POSIT regular multiplier in implementing the filter, POSIT outperforms floating point in all the performance metrics including area, speed, power, and energy by 35.68%, 20.66%, 31.49%, and 45.64%, respectively.

A Short History of Grading Practices at Dalhousie University (1901-2021)

Grading practices at Dalhousie University have changed considerably over the past 120 years. From 1901 until the early 1970s, Dalhousie used a variant of the British system. Initially, a grade of 65% or higher was required for distinction. In 1937, Dalhousie moved to a 2-category system (Distinction vs. Ordinary Pass) and in 1942 the distinction grade cutoff was lowered to 60%. By the late 1940s, the British system returns, “Second Division” was subdivided into Seconds and Thirds, and First Division required an 80% or higher. By the late 1960s, there were conversions between American letter grades (A, B, C, D), divisions, and percentage grades. Moreover, there was a 4pt “merit point” system that served as a prototype to Grade Point Averages (GPA). Experimental teaching and grading practices were explored in the 1970s. Officially, percentage grades were abolished and replaced with an 11-point letter grade scale from A+ to F. Unofficially, most professors and departments continued to use percentage-to-letter conversion schemes that were highly idiosyncratic, though they were eventually standardized within (but not across) departments. In the 1990s, the 4.3 GPA system was standardized university-wide largely because it was thought to give students a competitive advantage for federal scholarships. In the 2010s, Dalhousie standardized percentage conversion schemes across all departments into one unified Common Grade Scale, partially due to GPA requirements for scholarships and graduate schools. Overall, most grading changes in the past 120 years were implemented for the external communication value of grades rather than for their pedagogical value.

Migration of population in Sverdlovsk oblast: problems and solutions

In the context of the necessity to implement the national goals, one of the important areas of activity is support of positive demographic processes, promotion of population growth in the country, including through resettlement and migration of residents of other countries. This is relevant not only at the country level, but also at the regional level, each of which has features that must be considered when forming demographic policy. The article analyzes the effectiveness of the program to promote migration and resettlement of compatriots from other countries to Sverdlovsk oblast. Its advantages and limitations are highlighted, its effectiveness is considered on the example of immigrants from several CIS countries: Tajikistan, Kazakhstan, Kyrgyzstan. It is shown that despite the formal fulfillment of the objectives of the program (more than 28 thousand foreigners arrived in Sverdlovsk oblast within 9 years), some meaningful moments were missed, the selection of migrants based on the occupations in demand in the labor market of the region was not fully carry out. There are presented the directions of improving the program for the medium term, which are connected with new approaches to raising the quality of program implementation in Sverdlovsk oblast. It is shown that it is necessary to formalize and improve the mechanism for attracting foreign labor to the region using notification quotas, organized recruitment, modification of selection criteria for the point system, development of the material base and linguistic community for an accelerated adaptation. Analysis showed that promotion of resettlement is necessary with relation to professionals in relevant areas of activity (doctors, teachers), while the demand for unskilled labor is satisfied by migrants.

Gender Audit as Basis in Developing Modules for GAD Focal Persons in Mati, Davao Oriental, Philippines

Many countries across the globe, including the Philippines, have implemented Gender and Development (GAD) policies to reduce gender biases and promote equality. However, mainstreaming efforts have been challenging due to the scarce availability of learning resources in the local context. This study is an initiative to provide the GAD Focal Point System (GFPS) in the Department of Education – City of Mati with a primary reference in training their GAD Focal Persons on Gender Sensitivity, GAD Planning, and Budgeting (GPB). The coverage is based on their learning needs and gaps determined through participatory strategies involving the school administrators, teachers, students, and parents. Also, the results of the gender audit using the Gender Mainstreaming Evaluation Framework (GMEF) are used as a baseline in module development. The framework presents strategic directions that agencies need to follow to advance across stages. It was found that Mati’s primary and secondary schools are in the initial stages of gender mainstreaming. As such, GAD’s basic concepts and definitions are introduced, along with various forms of gender-based violence and the appropriate mechanisms to address them aptly. The essential steps in planning and budgeting are also detailed, providing an active experience among the participants. It is imperative to sustain GAD capacity-building initiatives to catalyze a more directed and engaged policy framework.

The self-directed learning readiness of access to HE students at city college Plymouth, United Kingdom

This study examines the levels of self-directed learning skills for students on the Access to HE course at City College and how these skills relate to their academic achievement. In this study, 101 students participated in a survey and their self-directed learning readiness was measured using the Self-Directed Learning Readiness Scale (SRSSDL). Achievement was determined using the Universities and Colleges Admissions Service (UCAS) tariff point system. The findings showed that 38% of students on the course had moderate levels of self-directed learning and 62% had high levels of self-directedness. The mean SRSSDL score for all students who took part in the study indicated just an above moderate level of self-directed learning. These findings suggest that areas for improvement should be identified and evaluated and strategies adopted with the help of the teacher to help improve students’ self-directed learning skills. Results from further analysis revealed that self-directed learning is strongly correlated with students’ academic achievement and that SRSSDL total score significantly predicted UCAS points ( p = .049). Based on these findings, including components of self-directed learning in teaching for students on the Access to HE course might be beneficial in improving their overall achievement.

Student questionnaire as assessment of quality monitoring of e-learning in medical education

The aim of the work is a comprehensive assessment of the teaching quality at the Department of Internal Medicine №1 of the Poltava State Medical University. The assessment of monitoring was an anonymous online survey of VI year education medical students that was trained at the modules “Current practice of internal medicine” and “Emergency conditions in the clinic of Internal Medicine” in the context of the COVID-19 pandemic. It was shown that, despite the greatest difficulty of the “Cardiology” and “Hematology” cycles, the overall assessment of the teaching availability for all cycles was 4,16±0,416 points and the value of any cycle was not lower than 4 (5-point system). Given the conditions of distance learning in connection with the COVID-19 pandemic caused by the coronavirus SARS-CoV-2 the average score of student satisfaction with the skills acquired was 3.59 ± 0.593. Students noted that the most difficult mastering practical skills were on the “Emergency” (16.14%) and “Cardiology” (15.18%) cycles. This indicates that any cases, situational tasks, demonstration videos can’t replace live communication with the patient, under the guidance of a teacher-mentor, work with modern equipment and simulators. These results reflect that students need bedside teaching activities on patients’ experiences with teacher-mentor. A targeted approach to teaching and evaluating the learning process encourages feedback from students to improve the quality of educational services. Thus, the data allow us to analyze the effectiveness of distance educational quality using anonymous questionnaires, to get feedback and respond to the identified shortcomings.

Differential equations of motion of a material point in the perpendicular plane to the plane of the gravitating disk

This paper presents an analytical solution of the differential equations of motion of a material point in the plane perpendicular to the plane of the gravitating disk. The differential equations of the problem under study and the applied Gilden's method are described in the works of A. Poincaré. Differential equations refer to nonlinear equations. The analysis of methods for solving nonlinear differential equations was carried out. The methodology of applying the Gilden method to the solution of the differential equations under consideration can be applied in studies of the problem of the motion of celestial bodies in the “disk-material point” system in perpendicular planes. To identify the various properties of the gravitating disk, an analytical review of the state of the problem of the motion of a material point in the field of a gravitating disk is carried out. Summing up the presented review on the problem under study, a conclusion is made. The substantive formulation of the problem is described, which is formulated as follows: the study of the influence of disk-shaped bodies on the motion of a material point and methods for their solution.
