When electrical engineering students start their instrumentation and measurement course, they have previously taken calculus, physics, probability, and statistics. However, they have problems to apply the knowledge they acquired to solve problems related to electrical measurements and variables in the profession, such as water flows, solar radiation, wind speed and water levels. This paper shows how to integrate all the concepts involved in the process to calculate measurement uncertainty in order to improve the way the results of measurements and/or error determination processes are described. For that purpose, this study presents an applied exercise and a methodological process by means of an example, where the value of a resistance is determined taking into account the data of voltage and current measurements and using few data. The objective is to focus the process on estimating Type A and Type B uncertainty and the factors that affect the measurement processes, such as uncertainty due to random variations of the measured signals, instrument defects, imprecision of the instruments, or their resolution. During the calculation of uncertainty proposed here, students use the probabilistic knowledge they have acquired after they determined the value of the uncertainty U from the combined uncertainty u𝑐 (R), where the coverage factor is taken into account. This allows us to learn about the importance of expressing the results with higher (+) or lower (-) values of uncertainty. In the exercise carried out in this work, R = 733.31 +/- 8.10 ohm.

Multi Method Approach

Engineering education researcher Rogers (2006) proposed that an assessment of engineering programs should use a multi-method approach to maximize validity and reduce the biasness of any one approach. Based on this reason, this study used two methods in the direct assessment of oral communication skills performance outcome of an undergraduate electrical engineering students’ Final Year Project (FYP) design experience. In the first method, the Oral Communication Assessment Rubrics adapted from Norback et al. (2008) was tested for its reliability, consistency in the scores and ease of use. This was to ensure that the results were descriptive of the expected students’ performance (Miller & Olds, 1999). Once faculty rater reliability was achieved and verified, the rubrics were refined and redrafted to obtain inter-rater scores for the assessment of the oral communication skills during the FYPII seminar presentation. Descriptive statistics were used to draw inferences from the inter-rater scores. In the second method, the researcher used the final grades of these students which were obtained from the faculty end-of-course assessment of their FYPII seminar presentation through the use of the faculty Seminar Evaluation Form (SEF). The scores obtained from SEF were reported in the Course Assessment Summary Report (CASR) in the form of the achieved Key Performance Indicator (KPI) of the students in each department in the Electrical Engineering Faculty (FKE).

This paper deals with lab design tools and their impact on the learning progression of first-year electrical engineering students. Project-based learning is an innovative domain of acquiring knowledge in engineering education, where the role of experimental setup and use of advanced technology imitates real-world engineering problems. This experimentation induces a desire to learn in newly inducted students and influences their minds to understand the applied content of engineering education thus resulting in improved retention rates in engineering programs. A Likert scale is used to generate statistics which suggest that an intelligent design of engineering lab by choosing advanced learning methodology for freshmen electrical engineering students improves their ability to absorb modern engineering concepts as compared to the classical lab setup.

At the University of Waterloo, students from many non-electrical engineering programs are required totake basic circuits courses. These courses are often disliked by students who do not see their relevance andcannot contextualize the material. In 2019 a new version of this course was developed to cater to the specific needs of civil engineering students. The new course was based around teaching civil engineers circuit theory through relevant examples and focusing on the content that civil engineers would reasonably be expected to see in the field.  Lab exercises were developed to encourage independent capacity in circuit building and deep understanding of sensors and instrumentation. Student satisfaction with the course and performance on assessments has increased with the changes.

Introductory Computing

Most Canadian engineering students take a computing course in their first year that introduces them to digital computation. The Canadian Engineering Accreditation Board does not specify the language(s) that can or should be used for instruction. As a result, a variety of languages are used across Canada. This study examines which languages are used in degree-granting institutions, currently and in the recent past. It also examines why institutions have chosen the languages that they currently use. In addition to the language used in instruction, the types and hours of instruction are also analyzed. Methods of instruction and evaluation are compared, as well as the pedagogical philosophies of the different programs with respect to introductory computing. Finally, a comparison of the expected value of this course to graduates is also presented. We found a more diverse landscape for introductory computing courses than anticipated, in most respects. The guiding ethos at most institutions is skill and knowledge development, especially around problem solving in an engineering context. The methods to achieve this are quite varied, and so are the languages employed in such courses. Most programs currently use C/C++, Matlab, VB and/or Python.

Improvement of orbits precision is one of the most important tasks of space surveillance catalogue maintenance. The solution of this problem is directly related to an adequate consideration of the errors of the coordinate information from the measuring instruments. The article consideresd a new method for estimating the precision of measuring instruments on the catalog orbits. To carry out such analysis, in PJSC «VIMPEL» special technological program was created. Main results of a study of radar errors with orbits of space surveillance catalogue was presented. Also, the results were compared with data of measuring instrument's calibration software complex. This software complex provides determination of satellite's position with errors less than 10 m. A new dynamic model of measuring instrument errors is proposed.

Flooding is a dangerous phenomenon, causing emergency situations and causing material damage, capable of damaging health, and even death of people. To reduce the risk and economic damage from flooding, it is necessary to forecast flooding areas. An effective method of forecasting emergency situations due to flooding is the method of remote sensing of the Earth with integration into geoinformation systems. With the help of satellite imagery, a model of flooding was determined based on the example of Tavda, the Sverdlovsk Region. Space images are loaded into the geoinformation system and on their basis a series of thematic layers is created, which contains information about the zones of possible flooding at given water level marks. The determination of the area of flooding is based on the calculation of the availability of maximum water levels at hydrological stations. According to the calculated security data, for each hydrological post, flood zones are constructed by interpolation between pre-calculated flood zones of standard security. The results of the work can be used by the Main Directorate of the Ministry for Emergency Situations of Russia for the Sverdlovsk Region.

Reference samples are commonly used for the calibration and quantification of nanoscale electrical measurements of capacitances and dielectric constants in scanning microwave microscopy (SMM) and similar techniques. However, the traceability of these calibration samples is not established. In this work, we present a detailed investigation of most possible error sources that affect the uncertainty of capacitance measurements on the reference calibration samples. We establish a comprehensive uncertainty budget leading to a combined uncertainty of 3% in relative value (uncertainty given at one standard deviation) for capacitances ranging from 0.2 fF to 10 fF. This uncertainty level can be achieved even with the use of unshielded probes. We show that the weights of uncertainty sources vary with the values and dimensions of measured capacitances. Our work offers improvements on the classical calibration methods known in SMM and suggests possible new designs of reference standards for capacitance and dielectric traceable measurements. Experimental measurements are supported by numerical calculations of capacitances to reveal further paths for even higher improvements.

This brief article provides a description of some new ideas about admission of university engineering students in Sweden. The current system of admission is based on upper-secondary school grades and the Swedish Scholastic Assessment Test. These measures are used for admission to all higher education. For many reasons, ideas for a new admission model have been proposed. This model includes a sector-oriented admission test, which the universities are supposed to use for different purposes, such as selection, eligibility, diagnostics, and recruitment.
