A hardware object is a capsule of circuits loaded into reconfigurable devices. It is dynamically constructed while an application run. Its driver is temporarily mounted on a real driver for a hardware module. The circuits axe suitable to preprocessing and postprocessing of robot systems. A commercial C++ compiler becomes an integrated design environment only attaching hardware object components and hardware object libraries.

The ability to explain the reasons for one's decisions to others is an important aspect of being human intelligence. We will look at the explainability aspects of the deep learning models, which are most frequently used in medical image processing tasks. The Explainability of machine learning models in medicine is essential for understanding how the particular ML model works and how it solves the problems it was designed for. The work presented in this paper focuses on the classification of lung CT scans for the detection of COVID-19 patients. We used CNN and DenseNet models for the classification and explored the application of selected visual explainability techniques to provide insight into how the model works when processing the images.

This paper aims to extract the computational logic of a hybrid method for online calibration of car-following models and apply it to a refined car-following model that incorporates the behavior of vehicles moving on the adjacent traffic lanes. This calibration method combines the concept of Kalman filters with the Takagi-Sugeno Fuzzy Inference System (T-S FIS). Furthermore, this paper analyzes the influence of the lane change behavior on the calibration process. The testing of the hybrid calibration method in the case of a refined car-following model uses real traffic data and it is followed by a discussion of the results based on day/night traffic behaviors.

A wide variety of fieldbuses have been set up in the industrial automation system in different time periods under different environment. Therefore, during the development of industrial automation systems and control applications, the developer has to consider the interconnection of heterogeneous fieldbuses. In the paper, a Heterogeneous Fieldbuses Interconnection Architecture (HFIA) is presented to interconnect heterogeneous fieldbuses in wide area industrial automation system. The HFIA provides an integrated software framework to interconnect heterogeneous fieldbuses. With the help of the HFIA, it is easy and fast to interconnect heterogeneous fieldbuses. At the same time, the HFIA can be used for high-level industrial applications to control, monitor and optimize the operations of the fieldbuses systems. Profilbus, CANbus and Ethernet/IP are adopted as case studies for the HFIA architecture.

A power-assist exoskeleton robot, which is directly attached to the user's body and assist the motion in accordance with the user's intension, is one of the most effective human assist robots for the physically weak persons. Many studies on power-assist robots have been carried out to help the motion of physically weak persons such as disabled, injured, and/or elderly persons. EMG-based control (i.e., control based on the skin surface electromyogram (EMG) signals of the user) is one of the most effective control methods for the power-assist robots, since EMG signals of user's muscles directly reflect the user's motion intension. However, the EMG-based control is not easy to be realized because of many reasons. The paper presents an effective human motion prediction method from the EMG signals using a neuro-fuzzy technique for the control of power-assist exoskeleton robots.

An approach to intelligent process automation based on distributed planning agents is presented in this paper. According to this approach a higher-level agent-based automation layer supervises an ordinary process automation system. The purpose of the agent layer is to monitor the operation of the lower-level automation system and semi-autonomously reconfigure its control logic when needed. The agent layer operates as a distributed planning and plan execution system, which creates and runs reconfiguration sequences on the ordinary automation system in order to adapt it to various situations. In this way the approach aims to increase the operational flexibility of the whole automation system. The approach is demonstrated with a laboratory test process where process startup scenarios have been imitated. Experiences from the initial test runs are also described.
