this paper presents a comparative study on various reaching laws within the sliding mode control approach for electrohydraulic active suspension systems under complex road conditions. Unlike traditional single bump profiles, this study evaluates the performance of constant, exponential, and power reaching laws with scenarios involving a speed bump, a pothole, and a sidewalk. the objective is to enhance vehicle handling and passenger *** address chattering in sliding mode controllers, we explore exponential and power reaching laws. Performance metrics for road holding and passenger comfort are compared withthose of a traditional PID control. Simulation results indicate that the exponential reaching law excels in both position and force control, potentially negating the need for hybrid control when used alone. However, hybrid control is necessary for constant rate or power rate reaching laws.

Due to changes in modern living habits, cardiovascular disease has risen to become one of the leading causes of death worldwide. In response, the use of artificial hearts has emerged as an effective method for treating heart failure. Investigating the patterns of mechanical injury to blood is crucial in advancing artificial heart technology. therefore, this article presents the development of a Taylor-Couette shear device capable of precisely controlling shear stress and exposure time. this design offers improved accuracy compared to previous iterations of the Taylor-Couette device. Additionally, the article proposes a research methodology for studying blood injury based on the characteristics of the device and the cells involved. the effectiveness of this research method is further explained from a biological perspective.

the soft robotics field offers a large variety of actuators and robots, complex structures and designs able to behave in a required way, offering speed and resistance and at the same time reducing the contact damage chance. the control of such structures using mathematical methods requires complex methods which evolved over time in the form of predictive control and even neural networks and genetic algorithms. the current paper presents ongoing research that can be found at the intersection of meta-materials and sensor technology. It approaches a simpler method of controlling a flexible actuator based on a shape memory alloy, the regulator being a two-state switch controller steered by a pressure force sensor. We propose a complete analogical electrical structure and analyze the performance of the outcome, focusing on time response. the present work also contains a brief description of a mechanical design proposal able to optimize the impact of the shape memory alloy used, in order to obtain an amplified actuation.

the paper deals withthe creation and application of a mathematical model designed for operational control of strength characteristics of items produced under conditions of open-hearth steelmaking. Variations in the chemical composition of the raw material as well as in the parameters and modes of smelting are used as controlling influences. the mathematical model is based on a neural network trained on a data set collected under batch production. Training, validation and testing of neural networks have shown that chemical composition parameters alone are insufficient for predicting the mechanical characteristics of manufactured products. the dependences of impact toughness of representative samples on chemical composition and melting conditions obtained as a result of virtual computer simulations allowed us to formulate recommendations to prevent product defects. It is noted that the dependences of strength characteristics of manufactured products on their chemical composition and melting conditions revealed through modeling have a complex non-linear character which sometimes does not coincide withthe known results obtained on laboratory samples in isolation from the real conditions of serial production. It has been shown that the developed neural network model enables selecting the chemical composition and smelting parameters which eliminate reject and maximize the strength characteristics of the resulting products. It also helps to optimize the chemical composition of products and save the most expensive alloying elements.
