An emerging space in interface research is wearable devices that closely couple their sensing and actuation abilities. A well-known example is MetaLimbs [39], where sensed movements of the foot are directly mapped to the actuation of supernumerary robotic limbs. These systems are different from wearables focused on sensing, such as fitness trackers, or wearables focused on actuation, such as VR headsets. They are characterized by tight coupling between the user’s action and the resulting digital feedback from the device, in time, space, and mode. The properties of this coupling are critical for the user’s experience, including the user’s sense of agency, body ownership, and experience of the surrounding world. Understanding such systems is an open challenge, which requires knowledge not only of computer science and HCI, but also Psychology, Physiology, Design, Engineering, Cognitive Neuroscience, and Control Theory. This workshop aims to foster discussion between these diverse disciplines and to identify links and synergies in their work, ultimately developing a common understanding of future research directions for systems that intrinsically couple sensing and action. © 2025 Copyright held by the owner/author(s).

This paper is focused on an environment mapping application using Lego Mindstorms. The main goal is to create a program for a robot that will be able to solve problems of movement and mapping in an unknown environment. We chose Java and the Eclipse programming environment as the programming language. Simple mazes in the shape of a rectangle and the letters C were created for the mapping of the environment by the robot. We used an ultrasonic and infrared sensor for sensing the environment. In the end, we present a comparison and the results of measurements of both sensors when mapping the environment.

The paper deals with the problem of assessing the characteristics of electromagnetic wave scattering on electrodynamic objects with a complex shape. A combined approach, which is based on the use of statistical methods, methods of fuzzy estimation, and expert analysis, is proposed. A numerical estimate was determined for the index characterizing the level of scattered electromagnetic fields. Linguistic values of the indicators based on expert evaluations were compared. Numerical evaluations of the characteristics of the electrodynamic objects surveyed were given. Based on the formed information base, the frequency of occurrence of different responses was calculated for the analyzed groups, which included objects with over reflections (which was considered as the main group, and objects without over reflections (which was considered as the control group). The values of the electromagnetic wave scattering angle limits under the analyzed scattering conditions were demonstrated. © 2022 IEEE.

The paper considers the problem associated with the construction of an antenna, based on the flat focusing reflector with waveguide slots of a square profile, filled with a homogeneous dielectric. Algorithms for antenna modeling and optimization are presented. Optimization is based on the use of a multi-criteria approach. The antenna directional diagram for the main frequency is demonstrated. Frequency dependences of antenna efficiency and aperture efficiency are shown. The illustration of the phase distribution that will correspond to the surface of the aperture for boundary frequencies is demonstrated. The illustration is given of the phase distribution at the emitting aperture at frequency for cutoff frequencies. © 2022 IEEE.

This paper delves into the longstanding debate surrounding the efficacy of open-book versus closed-book examinations in the context of higher education, with a specific focus on courses within the domains of Information Science and Humanities. The choice between these two examination formats has significant pedagogical implications, as it shapes the learning experience, assesses the depth of understanding, and influences student outcomes. To elucidate the advantages and drawbacks of each approach, this study employs a mixed-methods research design, incorporating quantitative data from student performance metrics and qualitative insights from surveys and interviews. The authors examine these two phenomena in a hybrid learning environment, which has proven to be a resulting effective tool for the impact of the COVID-19 pandemic. They explore how the cognitive demands and assessment criteria differ between these two modes of examination, considering the distinctive nature of disciplines within Information Science and Humanities. In Information Science, open-book exams are often regarded as aligned with real-world scenarios, reflecting the accessibility of information resources in professional contexts in the post-COVID era. In contrast, closed-book exams emphasize memory recall and analytical reasoning skills. We investigate whether these distinctions translate into varied learning outcomes, student satisfaction, and long-term knowledge retention. Within the Humanities subjects, where critical thinking, analysis, and interpretation are paramount, the debate between open-book and closed-book exams gains further complexity. We examine how each format influences the development of critical thinking skills, the ability to synthesize and apply knowledge, and the cultivation of a deep understanding of complex texts and concepts. Additionally, this paper explores the role of technology and digital resources in shaping the dynamics of open-book exams, and whether this evolutio

Synchronization is an important concept in parallel computing. Students are usually introduced to this topic during their undergraduate studies in courses devoted to operating systems or parallel computing. In this paper, we present some aspects of teaching a synchronization module in a parallel computing course and discuss the advantages of assigning students practical programming problems inspired by classical synchronization challenges, such as the "Dining Philosophers" problem.

Logical Image Acquisition and Analysis of Android Smartphones

引用

Journal of computer and Communications 2024年第4期12卷 139-152页

作者： Nursel Yalçın Tayfun Yıldırım Department of Computer and Instructional Technologies Education Faculty of Education Gazi University Ankara T&#252rkiye Department of Computer Forensics Institute of Informatics Gazi University Ankara T&#252rkiye

Android smartphones largely dominate the smartphone market. For this reason, it is very important to examine these smartphones in terms of digital forensics since they are often used as evidence in trials. It is possible to acquire a physical or logical image of these devices. Acquiring physical and logical images has advantages and disadvantages compared to each other. Creating the logical image is done at the file system level. Analysis can be made on this logical image. Both logical image acquisition and analysis of the image can be done by software tools. In this study, the differences between logical image and physical image acquisition in Android smartphones, their advantages and disadvantages compared to each other, the difficulties that may be encountered in obtaining physical images, which type of image contributes to obtaining more useful and effective data, which one should be preferred for different conditions, and the benefits of having root authority are discussed. The practice of getting the logical image of the Android smartphones and making an analysis on the image is also included. Although root privileges are not required for logical image acquisition, it has been observed that very limited data will be obtained with the logical image created without root privileges. Nevertheless, logical image acquisition has advantages too against physical image acquisition.
