The proposed approach uses a hierarchical clustering method on Simulink blocks to reduce the problem scale, and an integer linear programming (ILP) formulation to determine the core assignment solution, considering load balancing and minimization of inter-core communication across cores with different performances. Finally, we generate the parallel code of the model based on the core assignment solution for execution on the processors. We evaluate the proposed approach by comparing it with existing methods and generating the parallel code on a single-board computer with the big.LITTLE architecture to determine its effectiveness.</p> ZHAOQIAN ZHONG Copyright (c) 2019 ZHAOQIAN ZHONG Thu, 28 Feb 2019 04:48:56 +0000 Technological Approaches in Applied Social learning <p>Industry 4.0 covers the readiness of achieving expertise that impacts the society, strategy, talent and technology. Individual, social and economic demands pose ever-changing challenges for education and training even in today’s world. In spite of the shrinking rapidity, which progressively affects the cognitive, biological, and information offerings into the new insights on people learning, for an effective reformation to an even more miniature of scientific and technological connect, ultimately on the knowledge content. Today’s students will compete in a technological, diverse, multi-cultural world and must be prepared to thrive in that futuristic environment; therefore, it is vital that today’s pedagogy produce lifelong learners, who can succeed in a global arena. To ensure our educational technology progresses at the rate demanded by today’s ubiquitous digital learners, we are reviewing emerging technologies and traditional teaching methods and propose desirable changes. Further enhancement in student learning and outcomes through technology enabled learning builds alliances among institutional units, employers, community partners and provides the effective delivery of learning services and opportunities to students. Technology depends on the cleverness and the innovative application of theoretical tools from control and estimation for scalability through hierarchy and multi-modality. Educational technology enhances the learning experience for students, faculty, the university and community at large. Hence, to develop a richer context for student learning, covering societal inadequacies, injustices in empowerment to learning access among students, cross-cultural involvements, and opportunity to learn, we deliberate on the latest trends in pedagogy - intelligent tutoring systems and ICT integration that can be modified during their implementation to suit future needs for industry 4.0 requirements.</p> Krishnan Umachandran, Amuthalakshmi P, Roosefert Mohan T Copyright (c) 2019 Krishnan Umachandran, Amuthalakshmi P, Roosefert Mohan T Fri, 01 Mar 2019 04:56:53 +0000 Service-Oriented Architecture In Automation Industries <p><em>This paper addresses issues and difficulties in the advancement of cutting edge installed gadgets, applications and its administration that Service-Oriented Architecture (SOA) handles in Automation Industries (AI).Because of SOAs expanding knowledge and traces of the methodology received, just as the business points of interest advancement, the assembling business with SOA expresses deep complexity and yet simple usage in process of automation. The future assembling undertakings will be portrayed by as often as possible changing business sector requests, time-to-showcase weight, constantly developing new advances and, most importantly, worldwide challenge.</em></p> <p><em>SOA and web innovation have evolved its route to support an unavoidably arranged world in which billions of individuals and trillions of devices and gadgets will be interconnected in different ways. As a component of this development, Internet innovation is rising as the essential bearer for interconnecting – utilized in mechanical mechanization, car hardware, building controls, home robotization, service automation, and so on.</em></p> Dr.Festim Halili, Elida / Blakaj-Gashi,Msc, Selvije Blakaj MSc, Copyright (c) 2019 Doc.Dr.Festim Halili,PhD, Elida / Blakaj-Gashi,Msc, Selvije Blakaj MSc, Wed, 05 Jun 2019 00:00:00 +0000 Automated Translation Preference with a Bilingual Chatbot <p>Free, online language translation services are being used by people around to the world to facilitate communication. However, it takes time and effort for a person to load the Web page in a browser, copy and paste text into the site, and translate words. The process quickly becomes tiresome. Instead, some computer programs are providing automated translation. However, no studies have been conducted to determine the efficiency or effectiveness of such an approach. In this study, we compare how students used an English-based chatbot with and without German automatic translation. Results show that students took nearly 1.5 times longer than their stated upper time limit to manually translate. In contrast, the automated translation was at least 30 times faster. In addition, the students were significantly more satisfied with the automated than the manual system.</p> Mina Park, Milam Aiken Copyright (c) 2019 Mina Park, Milam Aiken Tue, 23 Jul 2019 00:00:00 +0000 Diabetic Exudate Detection in Color Retinal Images <p>Diabetic retinopathy is a vascular complication of long-term diabetes. It causes damage to the small blood vessels positioned in the retina. These damaged blood vessels affect the macula and lead to vision loss. Exudates are one of the early signs of diabetic retinopathy disease in the retinal image, which occurs due to built-up of lipidic accumulation within the retina. In this paper, an image processing method is presented for diabetic exudates detection. First, high performance pre-processing is applied not only for de-noising and normalization but also to remove artefacts and reflection that could mislead exudates detection. Then, morphological operations are applied for the final candidate segmentation. Eight region features are extracted from the exudate region then random forest classifier is applied to differentiate between exudates and non-exudates region. The proposed method is evaluated using e_ophtha_EX dataset, achieving 80% sensitivity and 77% positive predicted value.</p> Dalia Ali Copyright (c) 2019 Dalia Ali Sat, 10 Aug 2019 09:44:56 +0000 An Empirical Assessment of the Success of Road Asset Management System in Tanzania and Its Economic Value in Managing and Planning for Roads Pavement <p>The deployment of Information Communication Technology in the Road sector has contributed positively towards achieving the national goal of ICT for infrastructure development. However, the deployment of ICT software for Road infrastructure in underdeveloped countries has been done with duplication of efforts contributing to software failure. This study aimed in evaluating the effectiveness and economic values of the Road Maintenance Management System in Tanzania.&nbsp; The study deployed System Usability Scale Framework in 26 regions of Tanzania, and Kruskal-Wallis test was used for significance testing. The result indicates positive response of adopting and scaling the R<em>oad Maintenance Management System</em> to all 26 regions in the country with R<sup>2</sup>=0.863. The usability of the system remains steady for almost three years from 2017 to 2019. The economic value of system is found to be above average (61%), while the value for money is found to reach 76.5% of the expectation. It is therefore concluded that the use of ICT in planning for Roads Maintenance increases efficiency in delivery critical factors that facilitated decision making in road planning and also improves specific services delivery in government efficiency.</p> Vitalis Agati Ndume, Majige Selemani, Jesuk Ko Copyright (c) 2019 Vitalis Agati Ndume, Majige Selemani, Jesuk Ko Mon, 21 Oct 2019 06:45:58 +0000
