In this paper we studied the effect of engineering expertise in providing directional judgments. We asked two groups of people, engineers and non-engineers, to observe and memorize five maps, each including a four-point path, for 30 sec. The path was then removed and the participants had to provide two directional judgments: aligned (the imagined perspective on the task was the same as the one just learned), and counter-aligned (the imagined perspective on the task was rotated by 180°). Our results showed that engineers are equally able to perform aligned and counter-aligned directional judgments. The alignment effect due to the distance from the learning perspective was, in fact, shown only by non-engineers. Results are discussed considering engineering both learning expertise and specific predisposition.

Tracking graduate outcomes is a new requirement for engineering education in Canada. Working closely with curriculum developers and educational technologists, the School of Engineering at the University of Guelph has shown it is possible to put in place an effective process. The process requires engaged participants, an open-mindedness and integrated technologies to collect and report the data. Combining people, process and technology provides a way for data analysis to satisfy accreditation requirements and internal quality education metrics. This paper describes the approach taken and identifies strengths, challenges, and opportunities to be successful, and support the ultimate goal of curriculum improvement.

In currently, the revolution in a high-speed broadband network is the requirement and also endless demand for high data rate and mobility. To achieve above requirement, the 3rd Generation Partnership Project (3GPP) has been established the Long Time Evolution (LTE). LTE has established an improved LTE radio interface named LTE-Advanced (LTE-A) and it is a promising technology for providing broadband, mobile Internet access. But, better Quality of Service (QoS) to provide for customers is the main issue in LTE-A. To reduce the above issue, the packets should be utilized by using one of the most significant function of packet scheduling to upgrading system performance via determines the throughput performance. In existing scheme, the user with poor Channel Quality Indicator (CQI) has smaller throughput issue is not focused. In this paper, a Hybrid Weighted Round Robin with Shortest Job First (HWRR-SJF) Scheduling technique is proposed to enhance efficient throughput and fairness in LTE system for stationary and mobile users. In this proposed scheduling, to schedule users according to a different criterion like fairness and CQI. HWRR-SJF Scheduling has been proposed for scheduling of the users and it produces increased throughput for various SNR values simulated alongside Pedestrian and Vehicular moving models. The proposed method also uses a 4G-LTE filter or Digital Dividend (DD) in order to align the incoming signal. The digital dividend is used to remove white spaces, which refer to frequencies assigned to a broadcasting service but not used locally. The proposed model is very effective for users in terms of the performance metrics like packet loss, throughput, packet delay, spectral efficiency, fairness and it has been verified through MATLAB simulations.

The rate of unemployment among youths in Nigeria has assumed a worrisome dimension. More importantly that those affected are specialized graduates from tertiary institutions. The youth unemployment rate has been of persitent increase since 2014 from from 11.7% to 36.5% in 2018. It has been established that the vacancies exists, but the graduates lack the skills to match the jobs. Therefore, the aim of this paper was to identify the constructs and sub-constructs of employability skills that are needed to match Electrical Technology students with the labour market. The resaerch design is a qualitative metthod involving document analysis and interview protocol of stakeholders in electrical technology. The stakehoders were the academics and the employers. The documents were analysed using frequency matrix table. While the interview of the stakeholders (experts) were done thematically. To ensure the reliability of the constructs and sub-constructs, an item pool was constructed to determine the agreement and content reliability index for the constructs. From the item pool, 5 constructs and 193 sub-constructs were generated. These were constructed into instrument for expert review. Three experts in electrical technology rated the instrument for determining the aggreement level, using the Fleiss kappa approach. The percent agreement for the raters are 89.63%, 86.01%, and 81.86% respectively with a mean agreement of 85.83%. The 85.83% indicate an almost perfect agreement by the experts for each of the constructs in the instrument. This is very good for producing a functional framework of employability skills.

Those students who major in computer science and/or engineering are required to design program codes in a variety of programming languages. However, many students submit their source codes they get from the Internet or friends with no or few modifications. Detecting the code plagiarisms done by students is very time-consuming and leads to the problems of unfair learning performance evaluation. This paper proposes a novel method to detect the source code plagiarisms by using a high-level fuzzy Petri net (HLFPN) based on abstract syntax tree (AST). First, the AST of each source code is generated after the lexical and syntactic analyses have been done. Second, token sequence is generated based on the AST. Using the AST can effectively detect the code plagiarism by changing the identifier or program statement order. Finally, the generated token sequences are compared with one another using an HLFPN to determine the code plagiarism. Furthermore, the experimental results have indicated that we can make better determination to detect the code plagiarism.

Abstract Outcome-Based education is a performance-based approach for the curriculum development, a future-oriented learner-centered ‘Empowerment Paradigm’ that empowers and endorses all learners with future success. It is an influential and tempting way of restructuring and reorganizing engineering education. Washington Accord, an International accreditation convention, an independent agreement between signatory organizations to provide an external accreditation to undergraduate engineering programs. The accredited engineering programs that qualify an engineer to enter into the practice of professional engineers are equally recognized and acknowledged by other signatory countries and responsible organizations Pakistan Engineering Council (PEC) is a full signatory to the Washington Accord and a regulatory organization for the accreditation of engineering programs in Pakistan. To keep up the permanent membership status, it is the requirement of PEC to implement Outcome-Based in engineering degree awarding institutes in Pakistan. The main aim of Outcome-Based education in engineering education is to empower engineering students with the essential characteristics required to switch themselves into the engineering profession as a global and professional engineer. The focus of current research is to explore the philosophical and theoretical underpinnings of Outcome-Based education. Moreover, to unveil the current challenges in the implementation of OBE framework in engineering education.
