Ahstract- This study focuses on developing a gait asymmetry index and applying image processing techniques to cyclogram analysis. We evaluated gait asymmetry under different walking conditions, specifically examining the effects of wearing a knee brace and holding a weight in hand. Using inertial measurement units (IMUs), we collected gait data to analyze knee, hip, and ankle angles in the sagittal plane. The joint kinematics data were assessed using our proposed asymmetry index, which combines image processing techniques and linear regression models. The proposed asymmetry index incorporates cyclogram area, trend symmetry, and the longest length of the cyclogram shape, effectively capturing variations in symmetry and providing a comprehensive measure. The results demonstrate that the proposed asymmetry index can effectively distinguish between different gait conditions. The findings potentially offer insights for researchers and clinicians in human biomechanics, aiding in the planning of interventions and the assessment of motion patterns, as well as for developers of bipedal walking robots in the field of robotic locomotion, enhancing their ability to design hardware and evaluate motion patterns. © 2024 IEEE.

This paper reports on the development of a novel soft robotic system for remote ultrasound applications. Direct contact of the ultrasound probe with the patient’s body represents a safety risk and therefore control of the probe’s positioning and applied force is a crucial task. The proposed robot uses a passive control system that provides safe interaction between the robot and the patient by leveraging soft robotics technology. The soft robot’s structure can be considered as a nonlinear spring which can be designed to exert a safe force within the robot’s workspace to guarantee the safety of human–robot interaction. The literature suggests that effective ultrasound imaging of both the heart and abdomen requires six degrees-of-freedom. These degrees-of-freedom consist of three translational motions, which are achieved using a novel hybrid soft cable-driven parallel robot, and three wrist motions, which is based on a universal joint design. The experimental results show that the robot can achieve all these six degrees-of-freedom, and its blocking force can be engineered to generate a uniform force within the workspace.

As the earth’s temperature increases, efficient heating, cooling, and lean building designs are critical to ensure environmental longevity for future generations. Reducing the usage of chemically involved mechanisms such as cooling units with hydrofluorocarbon refrigerants and improving natural absorption or reflection of sunlight is vital for sustainability and mandatory in any intelligent city design. This paper focuses on active temperature control utilizing novel intelligent window system designs that permit interior and external fixation. In addition to providing new smart home capabilities, the proposed system aims to reduce energy consumption, further providing benefits, including consumer cost savings and a reduction of fossil fuel usage. The paper provides the experimental test bed design and prototype of the intelligent system termed TRASS (Temperature Regulating Autonomous Solar Shade). TRASS is a self-sufficient product with communication capabilities and autonomous use. As the experimental results show, the autonomous control of the prototype allows accurate temperature regulation by managing the amount of sunlight. The model incorporates rechargeable batteries and alternative energy, allowing older generational homes and buildings to employ the system without needing external power. The system continuously maintains necessary environmental conditions indoors without user interaction. However, TRASS permits manual adjustments to ensure proper management at desired conditions.

The incorporation of micro-heaters in medical analysis devices significantly aided in the miniaturization of such devices and shortened the processing time. Despite the fact that various micro-heater designs have been proposed, a high-speed heating rate for micro-heaters remain a challenge. The reduction of thermal mass allows for this high-speed to be accomplished. Furthermore, backside etching of the substrate is critical in increasing the rate of temperature change in thin-film micro heaters. This will speed up the thermal cycle, paving the way for high-speed, portable, and cost-effective medical devices like the polymerase chain reaction (PCR). The size of the backside opening, on the other hand, should be carefully chosen to ensure the heater's rigidity. The larger the backside opening, the faster the thermal change and the lower the stiffness of the chip. An accurate simulation investigation was performed in this study using the CoventorWare software tool to obtain the optimal back side design for the designed micro heater in which the temperature change process is accelerated while the chip's strength is maintained. This study allows us to achieve a high-strength, high-speed micro-heater with superior efficiency. The heater's dimensions are designed to warm up a chip of size 30x40 mm in accordance with Peltier's chip size. For the provided heater dimensions, a series of squares with side lengths of 2.5 mm per square and a distance of 1 mm between each square was found to be the best design for the backside etching. It raises the heating rate to 22 °C/s and allows the heater to withstand pressure up to 1.8 MPa. © 2022 IEEE.

A hybrid manufacturing process, deformation machining (DM) combines subtractive manufacturing with incremental forming. Monolithic components with complex profiles are created through the hybridization of manufacturing technologies, which also reduces the wastage of raw materials. The properties of geometry and surface quality of the fin made from the aluminum alloy Al-7075 T6 using the DM process's bending mode was examined in this research, as were the effects of various approaches, toolpath methods, and tool design. To achieve the desired shape for the machined fin, various combinations of arcuate and slanting fin toolpath techniques were explored utilizing both top-down and bottom-up methods. The bottom-up method and the arcuate toolpath strategy were used to investigate various tool profiles. Using the best combination of toolpath strategy and tool profile, named as the T3 tool profile, which has a 0.6 mm nose radius and a circular sector, bottom-to-top (BTT)technique, and arcuate toolpath method, components with better geometrical features and surface roughness (SR) were produced. The analysis of the forming force in the bending approach of the DM progression was further carried out using this optimal combination. © Published under licence by IOP Publishing Ltd.

In recent years, competition within Radio Frequency (RF) communication bands has led to an overlap between the U-NII-4 band used by low-cost consumer devices, and the Dedicated Short Communication Band (DSRC) used by the Georgia department of Transportation. Past research confirmed that this interference leads to drastic reduction in Packet Reception Rate (PRR) for Roadside Units (RSUs) and On-Board Units (OBUs) throughout the country, resulting in a reduction of stability between different components of the Intelligent Transportation System (ITS). Our research team set a goal to prove that a low-cost and simple modification can be made to RSUs currently in use that could increase PRR, by developing and testing RF technologies, primarily attenuators available on the market currently. These solutions could be easily adapted to infrastructure systems, and only require they run in-line with the stock antennas already in use. We were able to accomplish this goal, as well as made findings that may be beneficial within the world of RF communications for RSU devices.

This paper analyzes the strength of Message Digest Algorithm (MD5) by performing deep learning-based Encryption Emulation (EE) and Plaintext Recovery (PR) attacks. We convert randomly generated S12-bit arrays, messages, into 128-bit arrays, digests, with MD5 in different numbers of steps. Furthermore, two different structures of deep learning models, fully-connected neural network and Bidirectional Long Short-Term Memory (BiLSTM), are used in attacks and trained to analyze MD5 automatically. As a result, the BiLSTM shows better prediction accuracy than the fully-connected neural network. Moreover, the PR attack is more challenging than the EE attack.

This paper presents a privacy-preserving image classification scheme based on deep learning and photon counting imaging. The vision transformer-based deep learning model can classify the photon-limited color images, which represents the images sparsely by using a few photons. As a result, over 90 % of photon-limited images can be classified when at least 50,000 photons are used. Since some information from the original images is lost in the photon-limited images, it is challenging to recognize the personal information in the photon-limited images. Therefore, the proposed scheme can classify the images while concealing the portion of the information in the images.
