Outcome-Based Education: A Learner-Centric Pedagogical Framework with Case Studies in Digital Communication and Signal Processing Courses

Outcome-based education (OBE) is the buzzword these days in the education field which boosts students’ creativity through their active engagement in learning course contents. Their participatory learning in the OBE model is well supported by making them aware of learning goals and course outcomes. Due to this, the students develop themselves nicely in their working surroundings along with peers. This helps develop their interpersonal skills along with improving academic performance. This paper primarily outlines the implementation of a few key standards of OBE in teaching-learning of two fundamental courses in Electronics and Telecommunication Engineering. It then covers how OBE, and its consequences demand paradigm shifts in instructional design and evaluation practices. The discussion on OBE for courses on Digital Communication and Digital Signal Processing is explored with Program-Outcomes (POs), Program-Specific-Outcomes (PSOs), besides Course-Outcomes (COs). Analysis of POs along with COs attainment for these two courses reflects the importance of the OBE framework. The inclusion of engineering pedagogy and active learning strategies in this framework leads to enhancing students’ creativity leading to their growth in their professional careers.

Thus, this research aims to determine qualitatively whether this approach has been incorporated or not. The method proposed the search for information in literature, review of the study plans and survey to the program’s graduates. Thus, through the analysis of the three elements, it is determined that the program has taken its initial steps and indirectly includes competencies in its teaching process, but there are still gaps to fill to reach an explicit scope.

Web-Based Laboratory Inventory Application Using QR Code and RFID in Telecommunication Engineering Laboratories/Workshops

State Polytechnic of Sriwijaya is one of the universities that organize vocational education in Indonesia, by having a variety of laboratories to support its education. One of them is the Laboratory of Telecommunication Engineering Study Program, which has assets in the form of equipment/instruments used by its students to carry out practical activities based on predetermined courses. However, the current borrowing equipment system in the laboratory still uses a manual system, where students are required to fill out a loan form provided by the laboratory technician. In this case, the use of website-based applications as a medium for stock information and lending activities is expected to be an alternative in the inventory process. The prototype method is used in application development. Web-based applications are designed using the Laravel framework. After testing using a black box, it shows that all the functionality of the application system that has been designed runs properly and well. From the test results, the QR Code and RFID can display the scan results in the application quickly. A web-based inventory application with QR Code and RFID technology can assist in monitoring inventory and the process of borrowing equipment in the Telecommunication Engineering Study Program laboratory.

MODERN MATERIALS AND INNOVATIVE WELDING TECHNOLOGY USED IN THE CONSTRUCTION OF ANTENNA MOUNTS

Telecommunication, transport and civil engineering play an important role in new research areas. New antennas based on innovative materials are being developed. At the same time, the methods of antenna mounting with the use of high-strength materials to ensure high structural rigidity with the lowest possible weight are being planned. These materials include AHSS steels with ultimate tensile strength (UTS) up to 1700 MPa and elevated yield point (YS); however, welded joints made of these steels have much worse mechanical properties, compared to the native materials. In this paper, it was planned to test the MAG welding of DOCOL 1400M steel (AHSS group). Directly after welding, a micro-jet joint cooling was applied. It was determined to create thin-walled joints that could be used in the formation of antenna mounts.

Development of a web system for the record of Clinical History in patients of the State Center for Critical Care in Salamanca Gto.

Software development is a common practice carried out for different institutions, both public and private. The purpose of these developments is to improve processes, streamline tasks and keep a record and control of the information so that it can later be used for decision making. The development of the Clinical History software for the State Critical Care Center in Salamanca Guanajuato (CECCS) by the Academy of Network and Telecommunications Engineering of the Polytechnic University of Juventino Rosas, meets the requirements requested by the CECCS. This system was requested to replace manual processes that are carried out by medical and nursing personnel; these processes will be replaced by a digital registry, where the information will be permanently recorded in a database. This system starts with the registration of the patient who enters the CECCS for hospitalization, the system will assign a file number for its control. By means of this file number, the nursing staff will generate the records of both diagnosis and medications administered in the three shifts (morning, afternoon and night), these records will be carried out by means of the sheet concept (one sheet will be recorded per day of the patient's hospitalization) where each sheet will contain six pages which contain: physiological parameters, hydric response, respiratory parameters, clinical parameters, neurological assessment, device infection risk assessment, pressure ulcer assessment, burns assessment, pharmacotherapies, intravenous therapy, diagnosis and nursing standards. This system also has a role control per user, where, depending on the user's role, are the options that can be executed within the system. There is a user authentication at the beginning of the system, so that only authorized personnel can use and register the information.

Quantum Internet protocol stack: A comprehensive survey

Classical Internet evolved exceptionally during the last five decades, from a network comprising a few static nodes in the early days to a leviathan interconnecting billions of devices. This has been possible by the separation of concern principle, for which the network functionalities are organized as a stack of layers, each providing some communication functionalities through specific network protocols. In this survey, we aim at highlighting the impossibility of adapting the classical Internet protocol stack to the Quantum Internet, due to the marvels of quantum mechanics. Indeed, the design of the Quantum Internet requires a major paradigm shift of the whole protocol stack for harnessing the peculiarities of quantum entanglement and quantum information. In this context, we first overview the relevant literature about Quantum Internet protocol stack. Then, stemming from this, we sheds the light on the open problems and required efforts toward the design of an effective and complete Quantum Internet protocol stack. To the best of authors’ knowledge, a survey of this type is the first of its own. What emerges from this analysis is that the Quantum Internet, though still in its infancy, is a disruptive technology whose design requires an inter-disciplinary effort at the border between quantum physics, computer and telecommunications engineering.

Investigation of exact soliton solutions to Chen–Lee–Liu equation in birefringent fibers and stability analysis

This study is devoted to uncover the optical solitons and other solutions. The mathematical models used for this purpose is Chen–Lee–Liu equation in birefringent fibers which consist of two components form of vector solitons in optical fiber. This system involves group velocity dispersion (GVD) and self-steeping coefficients that model the propagation of soliton flow through optical fibers and other wave-guide mediums. By the virtue of two innovative norms known as modified exp(−ϕ(ϖ))-expansion function method and Φ6-model expansion method hyperbolic, periodic and plan wave solutions are constructed. The hyperbolic solutions are segregated as dark, bright, singular and their combo forms. Besides, the linear stability mechanism is used to attain modulation instability (MI) gain. By selecting suitable parametric values, numerical simulation and physical interpretations of the achieved outcomes are manifested with interesting figures presenting the meaning of the acquired results. The results reported in this paper can enrich the nonlinear dynamical behaviors of the given system and may be helpful in many fields like telecommunication engineering, mathematical biology, mathematical physics, optical fiber and also exhibit that employed methods are effective and worthy of being tested.

Quality of Experience in Telemeetings and Videoconferencing: A Comprehensive Survey

Telemeetings such as audiovisual conferences or virtual meetings play an increasingly important role in our professional and private lives. For that reason, system developers and service providers will strive for an optimal experience for the user, while at the same time optimizing technical and financial resources. This leads to the discipline of Quality of Experience (QoE), an active field originating from the telecommunication and multimedia engineering domains, that strives for understanding, measuring, and designing the quality experience with multimedia technology. This paper provides the reader with an entry point to the large and still growing field of QoE of telemeetings, by taking a holistic perspective, considering both technical and non-technical aspects, and by focusing on current and near-future services. Addressing both researchers and practitioners, the paper first provides a comprehensive survey of factors and processes that contribute to the QoE of telemeetings, followed by an overview of relevant state-of-the-art methods for QoE assessment. To embed this knowledge into recent technology developments, the paper continues with an overview of current trends, focusing on the field of eXtended Reality (XR) applications for communication purposes. Given the complexity of telemeeting QoE and the current trends, new challenges for a QoE assessment of telemeetings are identified. To overcome these challenges, the paper presents a novel Profile Template for characterizing telemeetings from the holistic perspective endorsed in this paper.

A New Handover Management Model for Two-Tier 5G Mobile Networks

There has been an exponential rise in mobile data traffic in recent times due to the increasing popularity of portable devices like tablets, smartphones, and laptops. The rapid rise in the use of these portable devices has put extreme stress on the network service providers while forcing telecommunication engineers to look for innovative solutions to meet the increased demand. One solution to the problem is the emergence of fifth-generation (5G) wireless communication, which can address the challenges by offering very broad wireless area capacity and potential cut-power consumption. The application of small cells is the fundamental mechanism for the 5G technology. The use of small cells can enhance the facility for higher capacity and reuse. However, it must be noted that small cells deployment will lead to frequent handovers of mobile nodes. Considering the importance of small cells in 5G, this paper aims to examine a new resource management scheme that can work to minimize the rate of handovers for mobile phones through careful resources allocation in a two-tier network. Therefore, the resource management problem has been formulated as an optimization issue that we aim to overcome through an optimal solution. To find a solution to the existing problem of frequent handovers, a heuristic approach has been used. This solution is then evaluated and validated through simulation and testing, during which the performance was noted to improve by 12% in the context of handover costs. Therefore, this model has been observed to be more efficient as compared to the existing model.
