Drone Pilot Identification by Classifying Radio-Control Signals
Analysis of interactions with remotely controlled devices has been used to detect the onset of hijacking attacks, as well as for forensics analysis, e.g., to identify the human controller. Its effectiveness is known to depend on the remote device type as well as on the properties of the remote control signal. This paper shows that the radio control signal sent to an unmanned aerial vehicle (UAV) using a typical transmitter can be captured and analyzed to identify the controlling pilot using machine learning techniques. Twenty trained pilots have been asked to fly a high-end research drone through three different trajectories. Control data have been collected and used to train multiple classifiers. Best performance has been achieved by a random forest classifier that achieved accuracy around 90% using simple time-domain features. Extensive tests have shown that the classification accuracy depends on the flight trajectory and that the pitch, roll, yaw, and thrust control signals show different levels of significance for pilot identification. This result paves the way to a number of security and forensics applications, including continuous identification of UAV pilots to mitigate the risk of hijacking

Urban pattern and architecture of traditional Omani foothill settlements: al-Ḥamrā and Birkat al-Mawz
Outside of Yemen, Oman arguably contains the most significant, active vernacular heritage within the Arabian Peninsula. While some research exists on settlement pattern and architecture of large settlements on the plains (e.g., Manah, Nizwa, Bahla World Heritage Site and Ibra), little research has taken place on the nature of Omani foothill settlements. The thesis makes an important contribution to Oman studies by addressing this gap through the study of the urban pattern and architecture of two vernacular foothill settlements – Ḥarāt al- Ḥamrā and Ḥarāt as-Saybānī in Birkat al- Mawz in the Dākhliya (Interior) region of central Oman. The two oasis towns evolved during the Yaariba Imamate (mid-17th century CE onwards) and served the purpose of harnessing the tribal support of two important groups in the process of consolidation – the Abriyīn and the Banī Riyām. This thesis argues that the two settlements – new towns by Omani standards – were unique additions to Omani settlement hierarchy, introducing a new category in between the larger settlements of the plains and the small, dispersed settlement pattern of the Oman Mountains. The settlements have been studied by analysing their morphology, or how they were established and evolved over time shaped by the key factors of topography, geology and tribal movement
A Pragmatic Analysis of Refusal Strategies in Management Communication
This study examines the refusal strategies employed in superior-subordinate communication during departmental meetings. It aims to reveal these strategies\u27 function, specifically exploring why individuals use particular refusal techniques in their interactions. Data is collected through observation of participants\u27 turn-taking patterns in departmental meetings. The findings indicate that both heads of departments and department members utilized direct and indirect refusal strategies. Participants employed two direct refusal strategies, as defined in the Beebe et al. (1990, pp. 55-73) framework, and five indirect refusal strategies: explanation, statement of alternatives, attempts to dissuade, acceptance functioning as a refusal, and silence. The most frequently used direct strategy is the non-performative statement, while the most common indirect strategies are explanation and statements of alternatives. Social power dynamics are evident in the heads of departments\u27 speech, as they seek to control dissenting opinions. Department members, however, exercise social power by forming coalitions to support specific viewpoints discussed in the meetings. Future research could investigate the politeness strategies used by superiors and subordinates in these meetings and their impact on influencing heads of departments
Unpacking Cultural and Linguistic Refusal Strategies in Jordanian EFL Discourse: A Conceptual Paper
Refusal strategies are ubiquitous linguistic tools employed in everyday communication. Understanding the application of these strategies is crucial for interpreting the reactions of those receiving the refusals. This study investigates the diverse refusal strategies Jordanian students utilize to explore the cultural and linguistic factors influencing their choices. Data will be collected through interviews and observations and analyzed using Beebe et al.’s (1990) framework. The anticipated results include the identification of the significant influence of linguistic and cultural factors on the forms of refusal strategies employed by the students. The study also expects to identify direct and indirect refusal strategies. Ultimately, this research will provide a foundation for future investigations into the syntactic and morphological processes underlying Jordanian students\u27 construction of refusal strategies in their interactions. A deeper understanding of these processes will contribute to a more nuanced comprehension of pragmatic communication within this cultural context

Teaching Translation Technology in Jordan Employability and Labor Market
Translator training programs worldwide offer translation technology courses to meet the market\u27s growing needs, and translation programs in the Arab world are no exception. Developing ‘technological competence’ should be reflected in the curricula of translator training programs (See, Kenny 2020, Pym and Torres-Simón 2020, O’Brien 2019). However, the focus on technological competence varies across translator training programs around the world. This study aims to pinpoint the importance of technology in MA programs in Jordan. Furthermore, it determines whether technology-connected courses are acknowledged in the program descriptions and objectives. To conduct this study, all the Universities with MA in translation and/or translation and English programs in Jordan were recognized. In addition, a corpus of all MA programs with translation technology courses, course descriptions, and program objectives was also gathered. As a final point, a comprehensive explanation and examination were carried out to recognize technology in MA programs in Jordan. The outcomes of this study indicate that ‘technological competence’ is widely disregarded in the huge mainstream of MA translation programs curricula in Jordan
