Numerical P systems(for short, NP systems) are distributed and parallel computing models inspired from the structure of living cells and economics. Enzymatic numerical P systems(for short, ENP systems) are a variant of NP systems, which have been successfully applied in designing and implementing controllers for mobile robots. Since ENP systems were proved to be Turing universal, there has been much work to simplify the universal systems, where the complexity parameters considered are the number of membranes, the degrees of polynomial production functions or the number of variables used in the *** the number of enzymatic variables, which is essential for ENP systems to reach universality, has not been investigated. Here we consider the problem of searching for the smallest number of enzymatic variables needed for universal ENP systems. We prove that for ENP systems as number acceptors working in the all-parallel or one-parallel mode, one enzymatic variable is sufficient to reach universality; while for the one-parallel ENP systems as number generators, two enzymatic variables are sufficient to reach *** results improve the best known results that the numbers of enzymatic variables are 13 and 52 for the all-parallel and one-parallel systems, respectively.

This paper presents a new way of multi-sensor performance evaluation and management in integrated navigation based on observability analysis. First, the general observability theory of linear systems was reviewed, and consequently a definition of local observability and local observability matrix were further introduced. Second, a scalar form of the degree of observability was present from the point of view of estimation quality. Third, the application of the degree of observability to integrated navigation systems was illustrated. As expected, the simulation results showed that the degree of observability can help us to gain the information about how observable a state-variable is, and can further function as an indicator to evaluate the performance of each navigation sensor and autonomously manage sensors in integrated navigation systems. © 2019 IEEE.

This paper proposed an automatic method for the classification of meningioma subtypes based on the unsupervised color segmentation method and feature selection scheme. Firstly, a color segmentation method is utilized to segment the cell nuclei. Then the set of shape feature vectors which are calculated from the segmentation results are constructed. Finally, a k-nearest neighbour classifier (kNN) is used to classify the meningioma subtypes. Experiment shows that the classification accuracy of 85 % is achieved by using a leave-one-out cross validation approach on 80 meningioma images. © Springer science+Business Media Dordrecht 2014.

A simplified mathematical model of the cryogenic distillation with application to the (13C) isotope separation column

引用

AIP Conference Proceedings 2012年第1期1425卷 189-192页

The isotope (13C) has a widespread application in many fields such as chemistry, physics, medicine, etc. To obtain a high concentration in isotope of interest, in our case (13C), it is used the method of cryogenic distillation of carbon monoxide (CO) which is based on the difference between the vapor pressure of (12C16O) and (13C16O) at the temperature of liquid nitrogen. Isotopic separation plant, used to obtain the isotope (13C), is a complex installation, with many inputs and outputs, rather difficult to control. Due to this reason, from the point of view of automation, it is needed a simplified mathematical model. This model can be determined only with some presumption and simplification assumptions. Using the physical laws, the hydrodynamic part of the process and the mass balance will be described by partial differential equations. In order to design a controller for the column, it is needed a transfer function or a statespace realization of the plant, which is the main contribution of the present work. Implementing this mathematical model will be the key element for describing and understanding the operation of the plant and for future development of process control strategies.

control concepts for mobile service robots are a key issue in robotic research. With the use of mobile robots in the domestic area, further challenges entails new designs facilitating efficient control concepts for fast motion with reduced computational capacity. This paper presents motion control designed for an autonomously acting two-wheel driven robot, which fits in a cuboid with 75x75x150mm. Due to the outstanding design of mechanical and electrical components, the robot is capable to perform high precision movements up to a speed of 2.5m/s, featuring a vision unit that allows a fast environment recognition interpreting current position based on an application dependent world model. Based on predictive control algorithms, trajectory tracking and point stabilization are facilitated. The use of real-time communication for all units allows fast interaction of all components exchanging information, which is indispensable for fast motion control. © 2006 IEEE.

The article gives the basic concepts of reliability, performance, durability, considers the issues of changing the technical state of the machine during operation. The models under consideration have the ability to introduce various perturbations in order to simulate physical defects, and numerical simulation on a computer made it possible to obtain solutions in the form of temporary realizations of oscillations for different states of the simulation object. The cooperative use of the full-scale method and mathematical modeling made it possible to reduce the volume of full-scale experiments and apply statistical methods of analysis in the problem of classifying the technical condition by constructing mathematical models of the probability of failure and uptime during their operating time. The content of the main types of machine states is revealed, considerable attention is paid to the issues of identifying and influencing failures and the causes of failures in the machine, the reasons for the loss of performance during operation. © 2023 IEEE.

In this work, an attempt is made for the first time to use the measurement pattern generated by morphological transformation quantified by Hausdorff fractal dimension (HFD) and classified with ensemble learning based on bagging. The proposed work uses three morphological transformations for image preprocessing: hit-and-miss transform (HMT), white (WHT), and black top-hat (BHT). The pattern texture of US breast images is described by extracting the HFD from the regions of interest (ROI) after the ultrasound (US) images have been preprocessed. The main objective of this study was achieved by comparatively analyzing the classification performance of features using the Random Forest (RF), Extra Trees (ET) classifier, and bagging ensemble method based on XGBoot classifier. In presented study, the XGBoost classifier and BHT image processing method give an accuracy of 89.8% in a binary classification, benign versus malignant breast cancer. © 2024 IEEE.

An increase in the frequency of oil spills in the sea, which adversely affects the maritime environment, led to the motivation for this article. Recent advances in technology have now made it possible to provide Unmanned Aerial Vehicles (UAV) systems with great processing capacity. They include all the features of a complete computer, while maintaining a really small size as required by this kind of system. This investigation takes advantage of the functionalities provided by existing MultiAgent Systems (MAS) to accomplish tasks between UAVs. The article presents a case study that uses the capabilities to perform the detection of oil spills.
