In recent years, the incidence of skin lesions has been one of the most rapidly increasing of all commonly occurring cancers. This deadliest form of melanoma must be detected early to be effectively treated. Because of the trouble and objectivity of human clarification, a significant research field has developed around the computerized examination of dermoscopy images. One reason to apply swarm intelligence systems is that an optimal solution can be advanced with a sensible computational application. This work introduces an artificial bee colony technique (ABC), distinctions, and applications. The planned ABC is a more suitable algorithm and one that requires smaller amounts of factors that need to be adjusted in comparison to other modern artificial swarm intelligence techniques (MASITs) for distinguishing unhealthy in skin tumor lesions. In these swarm's intelligence optimization algorithms have been positively executed for melanoma problems and provided extraordinary results guidance to better prediction and investigation of the skin cancer lesions. The experimental outcomes propose that the planned process proficient a developed accuracy associated to the ground truth (GT) used skin lesions’ dermatology. So, we will be able to use these in a future study with different databases. © 2020 EAI.

The paper presents the results of electronic control system development and study for the gas and diesel fuel supply for an autonomous locomotive multi-fuel engine. In modern engine control systems physical and software components are deeply connected, which makes it possible to implement digital control algorithms as a part of a cyber-physical system. This paper proposes an original fractional proportional-integral-differential control algorithm to increase the stability and quality of transients of a multi-fuel engine. The results of simulation and experimental probation prove the benefits of implementing this algorithm for the transition process time and the integral quality assessment in comparison with the classical algorithms, which allows reducing fuel consumption. © 2020 IEEE.

Hardware-in-the-loop simulation (HILS) allows a more realistic evaluation of control approaches than what is possible with pure software simulations, but without the actual complexity of the complete system. This is important for some complex systems such as orbital robots, where testing of the system is typically not possible after its launch, and an on-ground replica is used to validate the performance of such a system. In this article, an impedance-matching approach is presented to match the end-effector dynamics of a fixed-base robot manipulator with that of a target vehicle-manipulator system (VMS), while taking into account the redundant nullspace dynamics in a connected real-time simulation framework. This approach ensures that the forces and torques exerted by the system on the environment matches with that of the simulated system. The contact wrenches used in our approach are not obtained from numerical simulations, but rather from real physical interaction, which is one of the main advantages of our approach. The effectiveness of our method is validated by demonstrating various physical interaction tasks with the environment, using a suspended aerial manipulator as the target system.

Microbial consortia are promising biotechnological production systems with the potential to divide complex metabolic pathways into smaller submodules, as well as make products and consume substrates that monocultures cannot. Maintaining optimal cell population levels and preventing mono culture formation challenge bioproduction by microbial consortia. Optogenetics allows for regulating the expression of key growth-regulatory genes through light to modulate cell population levels. Model-based dynamic optimization can determine optimal light trajectories and inoculum sizes that maximize product synthesis while satisfying system constraints, e.g., safety, economic, or technical aspects. Further-more, closed-loop dynamic optimization can address system uncertainty to a certain extent; however, its implementation is challenging due to limited online sensors. Alternatively, here we propose to perform open-loop optimization with batch-to-batch model adaptation based on Gaussian processes for maximizing bioproduction by optogenetically assisted consortia. The proposed approach enables knowledge transfer from existing to new models, improving predictability and optimization performance in each batch while avoiding costly and time-consuming modeling experiments. Compared to closed-loop optimization, this strategy is easier to implement as it does not rely on online monitoring, contributing to the state of the art in optimizing bioproduction by microbial consortia. We outline the applicability of the approach using simulation experiments of an optogenetically assisted consortium for the biosynthesis of the flavonoid naringenin, considering both parameter and model structure uncertainty.

Expanding conformal prediction to system identification

Pattern Recognition 2025年 167卷

作者： Msaddi, Saleh Kumbasar, Tufan Artificial Intelligence and Intelligent Systems Laboratory Istanbul Technical University Istanbul34469 Turkey Control and Automation Engineering Department Istanbul Technical University Istanbul34469 Turkey

System Identification (SysID) is a cornerstone of control engineering, aimed at modeling system dynamics from input–output data. However, SysID approaches often overlook uncertainty quantification (UQ), which is crucial for robust decision-making. To address this gap, we propose Conformal System Identification (C-SysID), a model-agnostic framework for UQ in single-output and multiple-output SysID tasks. C-SysID transforms point predictions of any SysID model into High-Quality (HQ) Prediction Intervals (PIs) for single-output systems or Prediction Regions (PRs) for multiple-output systems, ensuring the true output is captured within the specified confidence level. For single-output systems, we use the Updated Residuals (UR) and Weighted Updated Residuals (WUR) methods to generate valid HQ PIs. In the case of multiple-output systems, we apply the Copula method and introduce the Updated Copula (UC) method, which captures output dependencies to generate HQ PRs. We empirically validate C-SysID on diverse single-output and multiple-output SysID datasets. The statistically significant comparative results show that the WUR method outperforms baseline methods, delivering tight PIs with the desired coverage. For multiple-output systems, our proposed UC method generates PRs that achieve accurate joint coverage while maintaining the compactness of PRs. The results highlight the effectiveness of C-SysID in UQ and enhancing uncertainty-aware predictions for SysID applications. © 2025 Elsevier Ltd

Microbubbles and nanobubbles have several characteristics that are comparable with millimeter- and centimeter-sized bubbles. These characteristics are their small size, which results in large surface area and high bioactivity, low rising velocity, decreased friction drag, high internal pressure, large gas dissolution capacity, negatively charged surface, and ability to be crushed and form free radicals. controlling and modeling fundamental properties such as nucleation and of the dynamics of these bubbles is key to successfully exploiting their potential in the growing number of applications such as biomedical diagnosis and therapy, antimicrobial in aquaculture, environment, engineering, stock raising and marine industry. Laser-generated bubble dimensions can be characterized with an optical setup employing a high power continuous wave green laser for bubble generation. In this work, non-resonant, self-excited due to structurally nonlinear properties of the hydrogel, bubble formation was modeled as functions of well-controlled parameters of the colloidal media that is multi-layered and anisotropic, engineered uniquely.

In the upcoming years, autonomous vehicle technology will advance quickly and spread widely. The most crucial component of such systems is vehicle localization or position estimation. The global navigation satellite system (GNSS) is the one of the most advanced positioning system currently in use. But the GNSS signals could be interrupted or degraded due to interference. Additionally, while GNSS delivers precise information for outdoor systems but is unable to provide a solution for indoor. An indoors-and-outdoors-usable device called an inertial measurement unit (IMU) sensor is employed in this paper to suggest a location estimate technique. The study's proposed IMU dead reckoning method makes use of novel techniques to filter noise data and accurately determine the position of the vehicle. The GNSS-based vehicle localization system can be improved by using this technique in GNSS-denied scenarios. In this paper, the IMU sensor's accelerometer, magnetometer, and gyroscope data are utilized to calculate the vehicle's velocity, orientation, and position. The experimental results on a real autonomous vehicle demonstrate that the system is effective, with average errors in rotation and translation of 1.03 degrees and 1.04 meters, respectively.

This work studies the classical pharmacokinetic-pharmacodynamic (PK-PD) model of Propofol for total intravenous anesthesia in response to intraoperative blood loss. Anesthetic and hemodynamic stability are impaired in the setting of trauma surgeries or major procedures with high hemorrhage risk. Blood loss has immediate effects on the cardiovascular system, but also affects the plasma concentration of the perioperatively infused drugs. During perioperative transition periods, when fast blood losses occur, the PK models on which the target-controlled infusion (TCI) is based should be updated. Then, the population-based parameters move towards an individualized strategy that accounts also for the actual blood volume in the patient. This paper evaluates the influence of changing blood volume on the PK model of Propofol, hence on the anesthesia state of the patient. The simulations also account for the hemodynamic responses due to the conflicting interactions of both hemorrhage and anesthetic drug infusion. This model has great potential for inclusion in multiple-closed loop control strategies of anesthesia-hemodynamic states, as it is simple and adapted from well-known PK models, for which control strategies are already mature.

The paper authors analyze the safety control systems synthesis problem for critical technological processes on the railway signalling and automation systems. It is shown that modern control systems for complex distributed systems, such as a railway transport system, are not implemented with absolute safety. Such systems safety is limited by considering only their own failures, control systems and their components external failures, as well as infrastructure objects failures that directly interact with control devices. Other infrastructure facilities are not considered in any way during automatic control and data transfer to on-board automation. We presents the theoretical principles for the safety train traffic control system synthesis, considering the capabilities of equipping infrastructure facilities with highly reliable and safe means of technical diagnostics and monitoring. A simplified structure of the central train traffic control complex is given, considering the diagnosing and monitoring results of all transportation process components. The conditions for the completely safety train traffic control systems synthesis are formulated. The tasks going with the safe control system synthesis problem are noted. The railway infrastructure facilities and rolling stock parameters comprehensive accounting will allow reaching a qualitatively higher level of train traffic safety.

The importance of a mature, maintainable design of automation software in Cyber-Physical Production Systems (CPPS) is continuously increasing since a growing proportion of the system functionality is implemented via software. As a result, system complexity is shifting more and more towards the software side. Quality characteristics such as flexibility, maintainability, and extensibility, whose importance is increasing in the context of Industry 4.0, are thus becoming harder to achieve. These challenges can only be solved through sound architectural design. While there is a common understanding of good software architecture and appropriate methods to achieve it in computer science, a suitable architecture definition for automation software that takes all relevant factors into account is still missing in the field of CPPS. Therefore, based on a workshop with international scientists with different perspectives on CPPS, this paper presents influencing factors on automation software architecture. On this basis, a joint definition for software architecture in CPPS, as well as challenges and future research potentials, are derived.
