Physical environments in the real world are complex, unstructured, and often delicate. Pneumatic soft actuators draw inspiration from the adaptability of living organisms, enabling them to operate effectively in collaborative environments. Due to their compliant nature, the soft actuators present a solution for robots to interact safely with human co-workers and their surroundings. Multiple challenges arise while designing these actuators such as modelling, sensing, and controlling their continuously deformable structures. To address these issues, this research presents the dynamic modelling and self-evolving fuzzy-based closed-loop control for Soft Bidirectional Bending Actuator (SBBA) using visual feedback. This study discusses the hyper-elastic modelling of SBBA for bidirectional actuation, establishing a non-linear relationship between applied pressure and bending angle. Exteroceptive feedback is obtained from colour markers, which is integrated with the proposed control method to regulate the input pressure to the actuator. Experimental results demonstrate that the proposed control methodology can render the desired angle with an improvement of 22.97% in rise time, 33.61% in peak overshoot, and 30.35% in peak time, resulting in faster response and lower energy consumption. © 2024 IEEE.

The future sixth-generation(6G) paradigm aims to seamlessly integrate communication and environmental sensing capabilities into a single radio signal, promising improved efficiency and cost-effectiveness through simultaneous data communications and environmental perception. At the core of this evolution, orthogonal frequency division multiplexing(OFDM) and its advanced waveforms emerge as pivotal for integrated sensing and communications(ISAC). This study introduces a concise and unified ISAC waveform design framework based on orthogonal multicarriers. This framework supports versatile applications of OFDM and its derivative waveforms within a generalized ISAC system, marking a significant leap in integrating communication and sensing capabilities. A distinguishing feature of this framework is its adaptability,allowing users to intelligently select modulation strategies based on their specific environmental needs. This adaptability optimizes performance across diverse scenarios. Central to our innovations is the proposal of discrete Fourier transformspread OFDM with index modulation(DFT-S-OFDM-IM). This framework is paired with newly proposed signal processing methods for single-input single-output and multiple-input multiple-output(MIMO) systems. Extensive evaluations highlight DFT-S-OFDM-IM's superiority, including dramatically reduced peak-to-average power ratios(PAPRs), competitive communication performance, and exceptional sensing capabilities, striking an elegant balance between communication capacity and environmental sensing precision.

Stroke patients perform resistance training during the recovery phase to regain muscle strength and neuromuscular functioning. The active ankle-foot exoskeletons (AAFE) available in the market, used for leg muscle training, have multiple actuators to facilitate multiple ankle movements. This increases the complexity, weight and makes the device less portable. In this paper, we propose an AAFE having a spatial mechanism that can facilitate variable resistance training during plantarflexion/dorsiflexion and inversion/ eversion using a single actuator. Based on the focus on the group of muscles to be trained, an independent motion is achieved by arresting the redundant joints. The paper presents the design and analysis of the AAFE, and the performance of the fabricated exoskeleton is demonstrated for three different training modes. © 2024 IEEE.

In the year 2021, a virtual reality training application has been developed, specifically for the Oculus Quest 2 headset, in order to allow the users to view and analyse 3D models for a wide variety of geometrical tolerances, tolerance zones and even the conformity condition and the datum features. This application allows the students to better understand the geometrical tolerances in accordance with the latest ISO GPS standards by using different 3D interactive models in order to highlight different types of geometrical tolerances and tolerance zones. In order to try to make the virtual reality training application more mobile and accessible for students, a mobile application, designed for the android operating system smartphones, has been developed. This application can facilitate better learning outcomes within the teaching-learning process by enabling the students to visualize a wide variety of 3D models representing different types of geometrical tolerances. Due to the dramatic evolution of technology in the past 20 years and the need to constantly keep up with it, the learning and teaching process suffered a massive change. The Covid pandemic has closed Universities all over the world and so, for the teaching process to continue, a sudden shift from traditional teaching to a more modern one involving the digital world was needed. Thanks for the fact that, nowadays, students are more inclined to use different types of mobile devices, the shift to the new learning paradigm has not left a great "scar" on student and teachers. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Manufacturing companies in particular, and technical enterprises in general, face a considerable number of risks in starting up and ensuring the continuity of the business. Aspects related to technological developments, market changes and other external factors, together with the internal transformations and the organizational capability, can lead to difficulties in which companies must assess their position in being able to carry out their business model and be competitive. The current article presents a case study in Romania in which the situations of the companies has been analysed using the Altman Z-Score, a metric specifically developed to perform a large-scale evaluation of manufacturing companies based on their recorded market and financial performance. The case describes the situations in detail and uses publicly available data to carry out the calculations, after which it proposes various improvement and intervention measures to reduce the pressures on the studied companies and restore their viability in line with the concept of second-chance technical entrepreneurship. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Robust security is tritical for smart homes to protect families and goods from potential intruder threats. Vision-based intruder detection systems are commonly used for this task. However, only a few households have adopted such security technology because of its high cost, which includes both expensive devices and service costs. To address this issue, a low-cost intruder detection system is investigated in this study, leveraging a Raspberry Pi 4 with a camera module. Smart resource utilization strategies are employed to enable on-device local processing for privacy preservation of sensitive video data. To achieve real-time processing on resource constrain hardware, efficient motion detection is accomplished using the frame subtraction technique, while rapid face detection is accomplished through the haar cascade utilizing Kalman filter. Face identification using OpenFace model is speed up by subsequent template matching technique. The proposed algorithm achieved an average frame rate of 22 FPS making it capable for real-time intruder detection with environmental constrain. © 2024 IEEE.

Gait dynamic stability evaluation on inclined surfaces for inverted or everted feet walking

Background: This study investigates gait dynamic stability on inclined surfaces while walking with foot rotational impairments such as everted and inverted feet. Walking stability is assessed during gait transitional periods i.e. weight loading and unloading phases. Methods: Foot rotational impairments (eversion and inversion) are imitated using wedged foot insoles. A total of ten healthy subjects performed five trials for each of the inverted, everted, and normal feet conditions. Experimental data was collected using a twelve-camera motion capture system and a force plate installed on an inclined platform. Lower limb joint kinematics were computed in Visual-3D motion analysis software to evaluate the degree of foot rotational impairments. Gait dynamic stability was assessed by analysing the centre of mass and centre of pressure signals as neuromechanical input and output responses respectively. Both signals were modelled in time and frequency domains and stability margins were quantified by applying Nyquist and Bode (N&B) methods from control engineering theory. Results: Stability margins quantified from N&B methods illustrated the loading phase as stable and the unloading phase as unstable gait transitions. During the loading phase, both rotational impairments illustrated a decrease in stability (p < 0,05) for the ramp ascent walk and an increase in stability (p < 0,05) for the ramp descent walk. However, there was no difference observed for the respective unloading phases. Results from neuromotor outputs (CoP-velocity) illustrated a strong interlimb correlation (p < 0,001) during gait transitional periods, implying a compensatory stability interaction exists between opposite limbs. Further, stabilities quantified from outputs were found greater in magnitudes than the instability quantified from inputs illustrating the robustness of neuromotor balance control. Conclusions: Results support the hypothesis that gait stability gets affected while walking with rotation
