    Revising Research Papers in English to Avoid Desk Rejection
    (Technical University of Cluj-Napoca, 2024-04-28) MUREȘAN Carmen
    In the rapidly expanding landscape of academic publishing, adhering to English for Research Publication Purposes (ERPP) standards presents significant challenges for second language (L2) writers. Beyond linguistic proficiency, mastering academic discourse conventions and argumentation structures is essential. Romanian researchers, in particular, face obstacles due to linguistic and structural differences between Romanian and English. These include mastering academic style, accurately translating technical terminology, and adapting to the conventions of international scholarly writing. Limited access to high-quality language support services and the pressure to publish in high-impact journals further complicate the process. These challenges not only hinder the clarity and coherence of research papers but also increase the risk of desk rejection, preventing valuable contributions from reaching the global academic community. By analyzing the revision of approximately 200 pages of Medical Robotics research intended for international journals, this study highlights the specific obstacles encountered in manuscript preparation and the role of revision in mitigating the risk of desk rejection. Furthermore, it underscores the need for structured training programs and language support mechanisms tailored specifically for non-native researchers to improve their writing skills and overall publishing success.

    A General Overview on the Current State of Computer-aided Translation
    (Technical University of Cluj-Napoca, 2024-04-28) SZASZ Maria Augusta , OLT Maria-Cristina
    Computer-aided translation software has been around for decades facilitating the production of accurate and consistent translations in all fields. The two major competitors in computer-assisted translation (Trados and MemoQ) have managed to ease the professionals’ work and help them produce more accurate translations. Machine translation as we know it today either if we use Google or DeepL Translate or even parallel corpora have made a quantum leap in the past years, being usable and useful in everyday context. This paper describes the types and categories of computer-aided translation technologies in use, their applicability, advantages and limitations. It will address the limitations openly and argue that the revision / post-editing process is key to producing quality translations. It will approach the features of the models based on the authors’ concrete examples. The examples contain excerpts from the translations made by the authors into/from English into/from Romanian and Hungarian.

    The Importance of Reflection in Language Teaching
    (Technical University of Cluj-Napoca, 2024-04-28) RUSU Delia-Georgeta , LITERAT Ruxanda
    Reflective practice plays an important role in the professional development of language instructors, allowing them to critically assess their teaching approaches, rethink instructional strategies, and respond effectively to student needs. This article delves into the concept of reflective practice in language teaching, by examining the theoretical foundations of reflection in education, key reflective models such as Kolb's Experiential Learning Cycle and Schön's theories, and discussing strategies for language educators to maximize the benefits of reflection. It also explores the emotional aspects of reflection, emphasizing their role in teacher development and resilience. By integrating reflective practice into language teaching, educators can create more dynamic and effective learning environments while advancing their professional expertise.

    AI in Language Learning and Teaching through the Magnifying Glass
    (Technical University of Cluj-Napoca, 2024-04-28) CODREANU Florina
    The present scene of AI development is more than ever polarized by two fundamental sides: pessimistic and gloomy on the one hand, though hopeful and enthusiastic on the other hand. ELT practitioners and professionals tend to favour the latter attitude and bring the current situation to their own advantage. In the recent years AI in language teaching and learning has conquered a few areas that before seemed reserved to teachers only. The impact is considered huge and the benefits undeniable. AI progress through the magnifying glass shows the researcher many opportunities and innovations, but also plenty of risks and even more limitations. The fore article follows, both narratively and critically, the dazzling encounter between AI tools and the ample field of teaching and learning foreign languages, especially English language. The meeting is not novel at all, nor the worrisome questions arisen along. However, a closer approach may cast some fresh light on this contradictory, still evolving matter of AI technology behind the process of teaching and learning.

    Remarks on the Legitimation Discourse of Text Generation. An Analysis of Writing Teaching Programs
    (Technical University of Cluj-Napoca, 2024-04-28) POLICSEK Cecilia
    The current article compares a number of underlying principles that have legitimized the benefit of reading and writing within the educational framework throughout the course of time with the recent discourse on Artificial Intelligence (AI) text generation. It does so by revising several ideas that have traditionally supported the study of reading and writing and contrasts them with the perceived benefits and threats of AI, as formulated by a number of important university writing programs. This contrastive consideration of the support of reading and writing, on the one hand, and the discourse on text generation, on the other, is meant to contribute to the assessment of the degree to which the notion of text generation-centered education is compatible with education, as defined by Humanistic standards.

    MOBILE APPLICATION FOR BLE INDOOR POSITIONING
    (Technical University of Cluj-Napoca, 2023-12-12) MĂLUȚAN Raul; BRISC Bianca
    Distance estimation in indoor localization is mainly solved by Received Signal Strength Indicator (RSSI). In our approach, the RSSI is determined empirically, and it’s used to estimate the distance between the user and beacons in a mobile app solution. Trilateration and Kalman filter help obtain better accuracy. The paper proposes a classical solution for indoor localization, but with features like blueprint implementation, Google Maps integration, and manual beacon positioning.

    SECURITY ISSUES IN INTERNET OF THINGS BOTNETS: A HIGH INTERACTION HONEYPOT APPROACH
    (Technical University of Cluj-Napoca, 2023-12-11) LAZAR Alexandru; BLAGA Tudor-Mihai; ZINCA Daniel; DOBROTA Virgil
    For a better awareness of the tactics employed by the malicious entities in Internet of Things, a system called Honeypot tricks the attackers into exploiting its “sweet” fake resources. While implementing nine types of devices only six of those were attacked. Despite this, the honeypot managed to capture attacks destined for three devices that were not implemented. Overall, several real-world attacks were captured and analyzed providing different indicators of compromise. No new threats were identified but the server only ran for a short period of time and with limited resources. This approach looks like a promising avenue for creating attacker profiles and collecting data on botnet behavior.

    UHF-RFID ANTENNA FOR SEMI-ACTIVE ASSISTED TAGS
    (Technical University of Cluj-Napoca – Romania, 2023-12-09) CRIȘAN Nicolae
    This paper proposes a new concept of using RFID tag antennas more actively in the identification process. This innovative concept is based on antenna native properties that allow RF harvesting for DC biasing, either from the reader or from other proximity RF sources at the same time. Nevertheless, for now, RFID identification tags without a self-DC power supply have become more popular and are referred to as passive. Eventually, both RF and light harvesting processes could be addressed as a foreseeable solution for identification range extension. Soon this trend will lead to the cheapest (printable) RFID tags at competitive prices closely shifted to those of the already mass-produced barcode tags, mainly in use today. The proposed semi-passive tag antenna is working by replacing the IMPINJ-MONZA chip with the EM4325 chip which can be DC supplied by a PV panel. This tag can work as RF energy harvester and can be DC biased as well, being the most capable for the proposed concept. The antenna is printed on paper using a metal powder ink printer and the tag is interrogated using a UHF-RFID reader. The harvesting for tag DC biasing is extended through a very small solar panel, which acts also as a substrate for the RFID antenna. Thus, the extended concept of the semi-active tag could increase the coverage and the sensing range of the reader significantly. This happens especially in daylight or when other nearby RF sources are available, otherwise, the tag will work as an ordinary one. This approach will allow the antenna to be shrunk even further near the Chu-Harrington limit.

    SPATIAL-SPECTRAL CLASSIFICATION OF HYPERSPECTRAL DATA WITH CONTROLLED DATA SEPARATION
    (Technical University of Cluj-Napoca, 2023-06-22) MICLEA Andreia Valentina; ABRUDAN Mihaela
    Exploring spatial-spectral data frequently involves classifying hyperspectral images using convolutional neural networks. Due to the high complexity of the data and the scarcity of available training samples, hyperspectral image classification presents significant difficulties. In the context of supervised classification, we find that traditional experimental designs are frequently misused in the spectral-spatial processing context, resulting in unfair or biased performance evaluation, particularly when training and testing samples are selected at random from the same dataset. Under these circumstances, the dependence caused by the overlap between training and testing samples may be artificially increased, in breach of the data independence assumption upheld by supervised learning theory. In order to prevent an unbiased classification result, we present in this paper a controlled strategy designed to minimize the overlap between the samples present in the training and the testing data sets. The proposed controlled sampling strategy ensures a more trustworthy generalization of the CNN model by minimizing the issues present in the random sampling approach, such as the inability to determine whether or not an increase in classification accuracy is due to the spatial information incorporated into a classifier or to an increase in the overlap between training and testing data sets. Experiments performed with a wavelet CNN on different HSIs, namely Indian Pines, Pavia University, and Salinas, ensure the generalization of the data under the assumption that the training and data sets are independent from one another, based on a controlled strategy. Considering the high dimension of the HSI image, as a pre-processing step, the evaluation of the proposed framework is done by PCA and FA methods.

    SECURE ACCESS WITH TELTONIKA GPS TRACKING DEVICES FOR INTELLIGENT TRANSPORTATION SYSTEMS
    (Technical University of Cluj-Napoca, 2023-03-27) ANDREICA Gheorghe-Romeo; STANGU Ciprian; IVANCIU Iustin-Alexandru; ZINCA Daniel; DOBROTA Virgil
    GPS tracking devices are widely used in industries like logistics, transportation, and security. However, they are susceptible to cyber-attacks, including Man-in-the-Middle (MITM). This study focuses on Teltonika GPS tracking devices and examines the impact of MITM attacks on their operation. We propose implementing encryption protocols and other measures to enhance the security and resilience of Teltonika GPS tracking devices.
