this paper presents a system designed to facilitate training for Motor-Imagery based Brain-computer Interfaces (MI-BCI). Usually, MI-BCI provide a bare minimum graphical interface for the subject, therefore the training is perceived as a chore;it is postulated that incorporating game design elements, a more entertaining training session is achievable, and a shorter learning period is needed. As such, medical rehabilitation techniques that rely on being familiar with successfully using MI-BCI, skills that are largely unknown to the typical patient, might be much earlier implemented. the paper presents the general architecture of our proposed system, how it is supposed to run, and the preliminary results obtained.

Infants at risk for developmental delays often exhibit postures and movements that may provide a window into potential impairment for cerebral palsy and other neuromotor conditions. We developed a simple 4 DOF robot pediatric simulator to help provide insight into how infant kinematic movements may affect the center of pressure (COP), a common measure thought to be sensitive to neuromotor delay when assessed from supine infants at play. We conducted two experiments: 1) we compared changes in COP caused by limb movements to a human infant and 2) we determined if we could predict COP position due to limb movements using simulator kinematic pose retrieved from video and a sensorized mat. Our results indicate that the limb movements alone were not sufficient to mimic the COP in a human infant. In addition, we show that given a robot simulator and a simple camera, we can predict COP measured by a force sensing mat. Future directions suggest a more complex robot is needed such as one that may include trunk DOF.

Age classification is a specialist field, and imbalanced datasets and hyperparameter tuning are essential issues that can increase the superiority of classification models. this study proposes a new method for age classification optimization using the Decision Forest training technique, focusing on hyperparameter tuning and handling imbalanced datasets. With substantial improvements in handling minority classes, this research aims to improve the model’s classification accuracy. A robust model that shows resistance to overfitting was created by utilizing the capabilities of the Decision Forest algorithm model. the accuracy and loss are excellent; the highest is K-FOLD 5: Accuracy: 0.9512 and Loss: 0.2172. this innovative study presents significant breakthroughs regarding age categorization and a workable approach for researchers to perform appropriate hyperparameter adjustments when dealing with imbalanced data. this represents a tremendous advance in the classification field and an exciting path of research and application

this paper focuses on designing a security system for a smart door lock using fingerprint sensors and passwords. the security system will consist of two layers, namely, fingerprint identification and password confirmation. A fingerprint sensor module will be integrated into the door for users to confirm fingerprints. the fingerprint sensor will take the fingerprint and forward it to the microcontroller for comparison. If the printout matches the saved fingerprint, the system will go to the password confirmation. the user needs to enter the correct password to unlock. If the user enters the wrong password more than five times, it will have to wait five minutes to continue and only those who are given the ID number can change the password. the system has results with an accuracy of 86.36% that can be applied for practical applicability.

the 5G information age requires a large number of marginal nodes distributed around users to provide digital services. By caching and processing data at edge nodes close to users, edge caching technology can effectively collaborate with cloud computing and edge computing to improve the transmission efficiency as well as network response time. Meanwhile, intelligent reflective surface (IRS) is a promising technology for achieving high reductions in hardware cost and power consumption as compared to traditional relaying systems. It provides reliable and scalable backhaul transmission for base stations and access points in ultra-dense networks, which is in line withthe requirements of 5G green technology. therefore, in this paper, we propose a collaborative edge caching method that effectively combines IRS-aided wireless communication and channel power-delay-profile to design joint caching decisions in a centralized manner through limited cache capacity, improving the quality of content delivery in information transmission. then we proposed a deep deterministic policy gradient learning method based on the framework of deep reinforcement learning along with self-supervision learning to predict IRS phases and collaborative caching strategies. the numerical simulation results show that the proposed algorithm has better convergence speed and learning accuracy than that of the existing algorithms, and is expected to be applied for future massive and dynamical content delivery applications.

A series of semantic segmentation models have achieved remarkable accuracy, but their high computational cost limits their practical applications in areas such as autonomous driving and robotics. Recently, some multi-branch real-time semantic segmentation models have been proposed to improve segmentation accuracy by introducing detail branches. However, there is a lack of auxiliary guidance in the design of detail branches, and there is a high computational cost problem in designing multi-branch information fusion modules. therefore, to address these issues, in this paper, we propose a real-time semantic segmentation model called DSNet, which achieves a good balance between speed and accuracy. DSNet consists of two branches: the detail branch and the semantic branch. the detail branch effectively extracts detail information by introducing edge loss as auxiliary supervision, while the semantic branch extracts deeper-level semantic information by increasing network depth and channel count. Finally, the fusion of detail and semantic information serves as the feature for predicting the segmentation map. To fuse the detail and semantic information, we design a novel feature fusion module called LSAF, which efficiently integrates features from different branches with low computational costs. Our method achieves a speed of 152.3 FPS with an accuracy of 72.8% on the CityScapes test dataset.

CPU instruction functional verification is a key process to ensure the correctness and reliability of a processor design. the method of generating test instruction sequences in random order will have the problem of correlation between test results and test instruction sequences. To ensure the reliability of test results, this paper proposes a method for generating CPU instruction function test sequences based on finite state machines. the method works by finding an Euler circuit in the state diagram of the CPU to be tested, and generating an instruction function test sequence based on the found Euler circuit.
