To address the pedagogical challenges in the fast-evolving fields of computer and software engineering, we have developed a mentorship-based experiential learning framework that incorporates flipped classroom, live-coding sessions, in-class open-floor discussions, and project-driven lab designs to maximize student learning outcomes. This framework incorporates a mid-size software project across two second-year computer engineering courses, embedding it vertically into the Computer Engineering curriculum at McMaster University. The project, typically suited for a two-semester standalone course, aligns theoretical knowledge with hands-on application both in class, during lab sessions, and asynchronously at home. With 35.5% response rate to the anonymous exit survey, the student feedback indicated significant improvements in classroom engagement, the overall learning experience, and the confidence in pursuing self-directed software projects. The framework has yielded promising results in its initial implementation, with ongoing efforts of continuous data collection, further framework optimization, and extension to upper-year courses.

Development of new technologies, especially Internet, creates conditions for electronic education. The paper presents effect of using Internet as one of the means for taking exams or colloquia in certain subjects in the field of electrical and computer engineering at the Academy of Applied Studies of Kosovo and Metohija, Department Uroševac – Leposavić. Namely, the idea for writing this paper arose due to the fact that, to some extent, this type of communication with students already existed. After taking certain subjects in the field of electrical and computer engineering, research of students was done through a questionnaire. For purposes of this research, a survey questionnaire was used, which included a sample of 58 students. The goal of this research is to examine stances of students on perceived usefulness of the platform and its upgrade for taking exams or colloquia and for other scientific areas on all study programs used in the teaching process. At the end, obtained results were analyzed, based on which conclusion was drawn that students are satisfied with this type of communication as well as with quality of the platform itself.

Ladies and Gentlemen, welcome to the 2021 16th International Conference on Computer Engineering and Systems (ICCES). Organizing this annual event has been a continuous success for more than a decade.

Like the previous few years, the conference this year adopts five tracks of scientific research

This paper describes a proposal for the development of Professional Ethics and Social Responsibility in the field of computer engineering, with the aim of contributing with a plan for concrete action to the general discussion space that is being addressed by the academic about the social role of technologies in our time. A model based on competency-based training is proposed to develop these essential concepts in the computer scientists’ professional training among programs within interdisciplinary areas so that they allow the development of Professional Ethics and Social Responsibility through a natural link with the technical tools and methods of the discipline itself. A computer engineering program is taken as an example and the project proposal is described based on objectives, courses, learning results and methodological strategies to create an experience related to Professional Ethics and Social Responsibility for students through studied cases of real problems that are analyzed within the specific technical field and the inherent social field.

My research in optimization at the Department of Systems and Computer Engineering at Carleton University has brought me into contact with researchers in the Department of Electronics, our sister department in the general field of Electrical and Computer Engineering (ECE), which has a major research thrust in computer-aided design (CAD) of very large scale integrated (VLSI) circuits. I have come to realize that the design of VLSI systems consists in large part of solving incredibly massive mixed-integer nonlinear optimization problems, together with enormous circuit simulations. This is impossible without the use of CAD techniques. Over time, ECE-CAD researchers have both borrowed useful standard techniques from operations research (OR) and have invented their own, often to deal with the sheer scale and complexity of the design problems they face. Interaction between the OR and ECE-CAD communities would seem to be a natural development. Coincidentally, the INFORMS Journal on Computing had an area entitled “High Performance Computation” that covered (i) the solution of OR problems using new computing technologies, (ii) the application of OR techniques in the design and use of highperformance computing and communication systems, and (iii) solution methods for ultra-large-scale OR applications. The viability of this area was debated during 2003 as some of its aspects migrated to other areas (e.g., the new “Telecommunications and Electronic Commerce” area), and the number of submissions declined. The area was eventually closed, although I argued that the overlap between OR and ECE-CAD, essentially covering items (ii) and (iii), was a very active research area. This Special Cluster of papers was conceived as a way to test that argument. I was recruited at the same time to prepare a tutorial on ECE-CAD for the 2004 INFORMS Annual Meeting (see John W. Chinneck, Michel Nakhla, and Q. J. Zhang 2004. Computer-aided design for electrical and computer engineering. H. J. Greenberg, ed. Tutorials on Emerging Methodologies and Applications in Operations Research. Springer, New York, 6-1 to 6-44). The preparation of the article reinforced my observation about the research overlap between OR and ECE-CAD. A search of the electrical engineering literature for 2000 through early 2004 turned up 46,725 papers mentioning “simulate” or “simulation” as keywords in the abstract, 14,216 papers mentioning “optimization” or “optimize,” and relatively smaller numbers for specific techniques such as “neural network” (6,251), “genetic algorithm” (2,603), “linear programming” (576), “simulated annealing” (448), and “branch and bound” (199). One surprise was the relatively small number of papers using the generic keywords “mathematical programming” (68) or “operations research” (37). The general conclusion of the tutorial article is that the OR and the ECE-CAD communities have much to offer each other. This is certainly the case for the papers gathered in this Special Cluster. We see known OR techniques adapted for use in ECECAD. In “Integer Linear Programming Models for Global Routing,” Behjat et al. apply integer linear programming in a heuristic to solve enormous NPhard connection routing problems for VLSI circuits. In “Task Scheduling in a Finite-Resource, Reconfigurable Hardware/Software Codesign Environment,” Loo and Wells use simulated annealing, genetic algorithms, and random search techniques to solve scheduling problems in hardware-software co-design. We also see new techniques specifically developed by the ECE-CAD community to deal with problems of extreme scale. In “A Projection-Based Reduction Approach to Computing Sensitivity of Steady-State Response of Nonlinear Circuits,” Pai et al. develop methods for sensitivity analysis in extremely large nonlinear programs, especially those in which the objective function is very costly to evaluate. The methods have special relevance for simulation-based

In this work, the interaction between 3D optical scanners and objects realized with different materials and colours was investigated. The interaction is mainly related to the translucency of some materials, such as polymers, which is a category of materials in ever-increasing demand by industry. At the same time, the increase of the geometrical complexity of manufactured parts raises the need for the use of 3D optical scanners thanks to their rapidity and effectiveness. Translucency causes a subsurface scattering effect that has been modelled for certain cases and affects the dimensional accuracy of measurements, as well as the quality of reconstruction. Recently, an investigation considered its effect in dimensional verification using a structured light scanner with fringe projection. In this work, the investigation is extended to other 3D optical scanners exploiting different measuring principles: laser, structured light based on phase shifting and gray code, and photogrammetry. This was done in order to study how the subsurface scattering effect can vary with the materials, colours, and also the measuring principle used. To this end, five miniature step gauges made of different polymers and colours were used, and the effects due to their different optical properties investigated. The analysis focused on dimensional verification of bidirectional lengths, first calibrated with a traceable coordinate measuring machine. The quality of the reconstruction was also evaluated through the flatness values.According to the results obtained, translucency of materials has a dual and significant effect: a measurement bias and an increase of the uncertainty due to the different quality of reconstruction retrieved. Thus, it has to be considered properly for each case.

Most engineered products/processes/systems have continually evolved to enhance their performance. However, they still need to further evolve towards having such characteristics as high precision, intelligence and autonomy. In this paper, an opto-mechatronic systems technology is introduced as one of the enabling techniques, for such evolution. It is an integrated multidisciplinary technology combining optical, electrical, mechanical and computer engineering fields, thus creating new value and functions as a result of integration. Such integrated technology is shown to be derivable from the key technologies of the optical and mechatronic engineering fields and to a variety of fundamental functionalities required to produce the systems. The obtainable synergy and the future perspectives of the technology are discussed in detail.

Computer engineering education (CEE) is concerned with preparing qualified computer engineers who can take the lead and innovation in the rapid growth of technology and computer engineering fields that dominate all aspects in our life. The issues of computer engineering education rely on a broad mathematical and scientific knowledge base. Before discussing issues related to CEE, a short description of computer engineering is helpful.


 
 
 
 The article presents a subsystem of exercises for the formation and fostering spoken language proficiency competences in English for future bachelors of computer engineering. The concepts of exercise and task are specified. Outlined types and kinds of exercises that we consider appropriate in the formation of spoken language proficiency competences in English for future specialists in the field of computer engineering. The stages of formation of relevant skills and abilities are defined and characterized. Teaching speaking and listening skills to the above-mentioned specialists takes place in 3 stages: 1) preparatory 2) receptive- reproductive / productive, receptive-productive, 3) productive. The purpose of the preparatory stage is to master the background knowledge and the formation of the language environment and language community. This stage includes receptive, receptive-reproductive exercises, exercises for the development of listening and speaking skills. The second stage, receptive-reproductive / productive, involves active training in oral speech with the help of appropriate professionally-oriented materials and situations. The exercises of the second stage are aimed at training students in monologue speech, namely at achieving and solving a communicative task, at expressing their own opinions; listening comprehension exercises take place in 3 stages - pre-listening, while listening, and after listening. Examples of exercises for development of listening skills are as follows: exercises for activating prior knowledge, listening for gist, exercises for discussing what was heard. During the final receptive-productive, productive stage, students do exercises to improve the acquired knowledge and developed skills. By this stage, students have already mastered the relevant professional disciplines, acquired appropriate speaking skills through the exercises of the second stage, and already have certain skills and professionally oriented knowledge in the field of computer engineering, so exercises such as role-playing games, projects, case studies are a logical continuation in the formation and fostering spoken(oral/vocal) language proficiency competences in English for future bachelors of computer engineering. Samples of the developed exercises are presented to each stage.
 
 
 

Progress in the fields of computer science and computer engineering has put considerable strain on academic departments to keep the curricula abreast of the "state of the art." This is a constant demand to modernize courses and programs. This usually takes the form of continually adding new courses, and including new material in existing courses.Our solution at the University of Colorado at Boulder has been to share the curriculum between the Departments of Computer Science and Electrical and Computer Engineering wherever possible. The teaching of Assembly Language programming is an example of a course taught to both Computer Science and Electrical and Computer Engineering majors. The course has two semesters of Pascal programming as prerequisites.
