Field programmable gate arrays (FPGAs) are based on a concurrent paradigm which allows the design of efficient hardware architectures and has positioned FPGAs as an ideal device for implementing compute-intensive applications. For this reason, FPGA technology has had a great impact in areas such as computer vision, where one of the main objectives for researchers working in this field is to create efficient automatic object recognition systems. Therefore, the need to provide undergraduates with the necessary skills to design FPGA-based object recognition systems is evident. With this aim in mind, it is essential that specialization courses related to the design of these systems include the required resources for the student to apply the theoretical knowledge in solving practical problems. In this article, we present a development tool designed to help students, teachers, and researchers during the design-modeling-implementation process of object recognition systems based on FPGAs. The proposed tool operates under a modular approach as this facilitates the working on any of the phases of a recognition system and it is considered as a hybrid because the other phases can be developed using a software language. An empirical evaluation involving undergraduates enrolled in a Computer Engineering program was conducted to create a hardware architecture for the DAISY descriptor that uses the homogeneous features of objects immersed in images to produce an efficient representation. By considering similar descriptors such as Scale-Invariant Feature Transform (SIFT) and Histogram of Oriented Gradients (HOG), DAISY is computed by convolving orientation maps instead of using weighted sums of gradient norms, which offers the same kind of invariance at a lower computational cost for the dense case. The results obtained during such an evaluation indicated that students consider this FPGA-based tool to be an alternative to receiving practical training on designing systems for solving problems related to the area of object recognition.</p>","PeriodicalId":50643,"journal":{"name":"Computer Applications in Engineering Education","volume":"32 3","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139925364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, evaluating usability is not an easy task for nonexpert evaluators. To facilitate this evaluation task, this article presents a Methodology for Usability Testing (MUT) and a system (CALMUT) that assists nonexpert evaluators in the application of the methodology by automatizing the calculations and facilitating their interpretation. This can be very useful for learning and instructional designers but also to people involved in the decision of introducing or not a new educational software. To develop the proposal, a literature review of different usability metrics, methods, and systems was carried out first, followed by a selection and adaptation for novice usability evaluators. This article also presents a case study where lecturers tested the usability of an educational software following the proposal and shows that using MUT and CALMUT helps people without previous experience detect the main usability problems of educational systems before deciding whether to use them or not.</p>","PeriodicalId":50643,"journal":{"name":"Computer Applications in Engineering Education","volume":"32 3","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cae.22725","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139927982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The shift to online or hybrid learning models posed a significant challenge for educators, particularly those lacking digital skills. The study sought to answer several research questions, including the impact of online versus in-person teaching on preuniversity students and gender differences in Computer Science perception, and Computational Thinking skills performance. The study employed a four-phase methodology, consisting of pre- and posttraining measurements of Computer Science perception and Computational Thinking skills development through specific activities delivered in-person or online. The results indicate that in-person training is more effective for developing Computational Thinking skills, particularly at the secondary education level. Furthermore, there is a need to focus on maintaining girls' interest in Computer Science during primary school, as interest levels tend to decline significantly in secondary school. These findings have significant implications for Engineering Education in the context of digital transformation and the increasing importance of Computational Thinking skills in various fields of engineering.

In search of this balance, the study, analysis, and evaluation of human–machine interaction are crucial, as are correctly identifying the tools through which this interaction is achieved. Extended reality (XR), emerging technology within Construction 4.0, seems to be a tool that offers an environment conducive to achieving these interactions and meeting the objectives sought. In civil engineering, efforts have been directed towards the study and development of applications of XR experiences rather than the application of this technology in a transcendental way in civil engineering training.

An empirical investigation was conducted using a quantitative approach, a quasi-experimental design, and pretest–posttest measurements without a control group. A one-sample <i>t</i>-test for comparison of the means of a sample was used. Statistically significant differences were found between the theoretical and empirical mean of the variable motivation to learn in the specific context and the variable Stimulus for learning after interacting with the mobile application. The means were higher than the theoretical average of the scale, which suggests that the participants valued the mobile application positively. Regarding the learning outcomes of the Scrum framework, a paired sample <i>t</i>-test for comparison of means revealed an increase in posttest scores, although this rise was not statistically significant.

In today's highly competitive industries, graduates need to be productive from Day one as they enter the industry. To meet the vast range of industrial requirements or even for higher education, education institutes must adhere to an industry enabled curriculum as defined in collaboration with industry employees. As students reach their prefinal year of mechanical engineering studies, they will encounter courses like finite element analysis, design of machine elements, and failure analysis in design, which will serve as foundation steps for their future careers. As students need to compete in the real world, it becomes imperative to have a thorough understanding of both theoretical and practical issues. The focus of current work is to provide them a platform to think as a real-time problem-solving engineer to address the society-based problems and how he/she approaches the problem in an optimized way and finally, convert the entire work to tangible documents in the form of research articles. Since 2018, a new vertical called as “advanced computer aided engineering (CAE)” has emerged to link and prepare people for the business. In the realm of finite element method (FEM) theoretical and allied laboratory work, the current study discusses sustainability while selecting the problem statement. The entire emphasis is on eco-environment with nature's sustainability along with the go-green concept in terms of materials, design, optimization, cost, quality, and so on. The present work includes several new features that were not present in the previous curriculum, such as transforming the work to high-quality journals, student feedback, subscription-based journal selection for the manuscript, and embedding experimental and analytical work alongside simulation studies. This time, 40 teams participated, with around 36 project works being qualified for publication in prestigious journals and 8–10 works being filed for Indian patents. In terms of quality and quantity of work completed, this is the best output attained in contrast to previous iterations. Because of the increasing growth rate of higher education, our students have been able to get into Top 100 QS ranked universities. The figures show that because of faculty involvement in the FEM lab, Advanced CAE I, and Advanced CAE II, over the previous 4–5 years, students were able to publish more than 50 publications in prestigious peer-reviewed International/National Journals and Conference papers.</p>","PeriodicalId":50643,"journal":{"name":"Computer Applications in Engineering Education","volume":"32 3","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139772987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
