In the recent times, it has been observed that most of the biometrical research work has been carried out either using template-based or knowledge-based approach. In the present paper, behavioural patterns have been determined through human-gait image through knowledge-based modelling using soft-computing technique. Very little amount of work has been carried out with knowledge-based or model-based approach using soft-computing tools like artificial neural network, fuzzy set theory and genetic algorithm. In the present work, soft-computing technique has been applied for the detection of behavioural patterns like: normal behaviour and abnormal behaviour. The work has been carried out in two phases. In the first phase, a knowledge-based model called artificial noise-free human-gait model (ANFHGM) has been formed. The model has been formed by considering an input human-gait image that has been enhanced and compressed for the removal of distortion with loss-less information. Later on it has been segmented using the mechanism for the detection of the region of interest along with object of interest. Hence the relevant geometric features have been extracted and stored in the form of a corpus. In the second phase, ANFHGM has been utilised for the determination of behavioural patterns with a test human-gait image. The process has been done by considering an unknown human-gait image for the detection of normal and abnormal behaviour patterns of the subject. For this an algorithm, known as BPDSC (behavioural pattern detection using soft-computing) has been proposed in the present paper. The algorithm has been tested with 15 subjects of varying ages on a flat and plain surface. The result has been found very satisfactory with the tested data sets. © 2015 IEEE.

The 'Systems engineering' is currently applied to face the complexity of products overall their life cycle. Methodology, language (SysML), tools (software) and documentation of this approach are used to preliminarily define the system behaviour, without resorting to numerical equations, which are used then in mathematical modelling, only once that a trade-off of the system architecture was performed. In case of a mechatronic system identifying the real contents of 'smartness' is rather difficult. Specific standards are very seldom available. An effective design should identify the smallest number of active functions required to greatly improve the efficiency and to simplify its architecture. This paper shows an example related to the suspension of a high speed rotor and how the 'Systems engineering' allowed defining the requirements of smartness directly connected to some customer needs. Function herein analyzed is the coiling system usually exploited at the end of the rolling mill to shape the steel rod as a coil to be then delivered.

The growing percentage of incidents connected with human error in several industries has led to investigate the factors influencing failures, so that many methods, the so- called human Reliability Analysis methods, have been developed in order to quantify the human error probabilities. According to the needs of the last generation of the above mentioned methods (i.e. dynamic HRA methods), in order to overcome the lack into modelling the dynamic nature of human performance, this paper focuses on System Dynamics approach to highlight the relationships among the factors that influence human performance. Starting from a literature review on human error taxonomy, a Causal Loop Diagram is proposed to represent in a graphical fashion the interrelations between the variables which most influence and are influenced by human behaviour within a socio- technical system. © Springer International Publishing Switzerland 2015.

In this paper a nano-swimmer with length between 10 to 100nm consisting of a motor, filament and hinged boundaries is controlled by mathematical simulations successfully. A nano-swimmer that lies in a heterodimer magnetic nano-particle is proposed based on existed nano-robots. Dynamic of swimming is simulated by using some sequence of shape changes where magnetic forces act on one-ends of nano-swimmer. This idea is applied to simulate drug delivery from specific point of human body to the targeted point where it is assumed transport drug lies in a nano-particle. Here, the hyper-diffusion equation that is a fourth order partial differential equation is proposed to model swimming at nano-scale. The unknown control function ( magnetic force) that acts on the boundary is calculated to minimize the drug delivery energy cost. Two novel algorithms for the computation of optimal boundary control and estimation of its error function are proposed. Shape function deformations for the elastic tail of the nano-swimmer for various finite times are depicted. Numerical results for the control function for the nano-scale drug deliver are presented.

Advanced Issues of Wind Turbine modelling and Control 12

Advanced Issues of Wind Turbine Modelling and Control

12th European Workshop on Advanced Control and Diagnosis (ACD)

作者： Simani, Silvio Univ Ferrara Dept Engn I-44123 Ferrara FE Italy

The motivation for this paper comes from a real need to have an overview about the challenges of modelling and control for very demanding systems, such as wind turbine systems, which require reliability, availability, maintainability, and safety over power conversion efficiency. These issues have begun to stimulate research and development in the wide control community particularly for these installations that need a high degree of "sustainability". Note that this topic represents a key point mainly for offshore wind turbines with very large rotors, since they are characterised by challenging modelling and control problems, as well as expensive and safety critical maintenance works. In this case, a clear conflict exists between ensuring a high degree of availability and reducing maintenance times, which affect the final energy cost. On the other hand, wind turbines have highly nonlinear dynamics, with a stochastic and uncontrollable driving force as input in the form of wind speed, thus representing an interesting challenge also from the modelling point of view. Suitable control methods can provide a sustainable optimisation of the energy conversion efficiency over wider than normally expected working conditions. Moreover, a proper mathematical description of the wind turbine system should be able to capture the complete behaviour of the process under monitoring, thus providing an important impact on the control design itself. In this way, the control scheme could guarantee prescribed performance, whilst also giving a degree of "tolerance" to possible deviation of characteristic properties or system parameters from standard conditions, if properly included in the wind turbine model itself. The most important developments in advanced controllers for wind turbines are addressed, and open problems in the areas of modelling of wind turbines are also outlined.

Cyberphysical systems, with their interdependence between physical behaviour and digital control, need insights from frequency domain control engineering, state space control engineering and discrete formal systems theory for their proper description. Neglecting any of these, results in descriptions that omit essential details. Hybrid Event-B is a formalism that enables all the relevant detail to be assimilated. A case study based on yaw control for the KURT e-vehicle is used as a testbed to explore the effective interaction between the various needed disciplines in exploring a specific design issue, the formalisation of yaw control discretization, using Hybrid Event-B.

In this paper we are concerned with the numerical solution of the discrete FitzHugh-Nagumo equation. This equation describes the propagation of impulses across a myelinated axon. We analyse the asymptotic behaviour of the solutions of the considered equation and numerical approximations are computed by a new algorithm, based on a finite difference scheme and on the Newton method. The efficiency of the method is discussed and its performance is illustrated by a set of numerical examples.

Security managers face the challenge of designing security policies that deliver the objectives required by their organizations. We explain how a rigorous modelling framework and methodology - grounded in semantically justified mathematical systems modelling, the economics of decision-making, and simulation - can be used to explore the operational consequences of their design choices and help security managers to make better decisions. The methodology is based on constructing executable system models that illustrate the effects of different policy choices. Models are compositional, allowing complex systems to be expressed as combinations of smaller, complete models. They capture the logical and physical structure of systems, the choices and behaviour of agents within the system, and the security managers' preferences about outcomes. Utility theory is used to describe the extent to which security managers' policies deliver their security objectives. Models are parametrized based on data obtained from observations of real-world systems that correspond closely to the examples described. Copyright © 2015 ICST.

An eigenspace-based method with a user adaptation scheme for human gesture recognition by using Kinect 3D data

APPLIED mathematical modelling 2015年第19期39卷 5769-5777页

A Kinect sensor has been used in several applications and is considered a novel interaction interface between humans and computers because of the simplicity of the acquired image data. The sensing image data obtained using the Kinect sensor includes depth measurement information and, therefore, the (x,y,z)-coordinates of 3D objects. This study proposes an eigenspace-based method for recognizing human gestures by using Kinect 3D data. The developed approach, called Eigen3Dgesture, involves employing principal component analysis to derive significant Eigen3Dgestures possessing the most critical information from Kinect 3D data. To facilitate establishing the eigenspace of Kinect 3D data, this study developed a frame filling algorithm before performing eigenspace construction. To enhance Eigen3Dgesture and the performance of the constructed eigenspace of Kinect 3D data, a user adaptation method for Eigen3Dgesture was developed. Fourteen classes of active gestures were subjected to human gesture recognition experiments. The experimental results demonstrate the superiority of Eigen3Dgesture with user adaptation.

The integration between health and engineering areas promotes the increasing precision of medical devices, making the diagnostic process progressively more accurate and safe. In this context, the integration between Product engineering and Dentistry has provided tools development that translates human reality through mathematical concepts aiding complex processes, such as dental implant. This research presents the development of a system for teeth and gums detection using Matlab (R) aiming the acquisition of the point cloud for teeth and gums 3D reconstruction in a CAD system. The development of this system has aimed to support dentists in their diagnostics, offering easy understandable information and creating a tool that can help the elaboration of auxiliary masks for dental implant process. The developed system also allows easy DICOM images manipulation, utilization of edge filters, highlighted of specific range of bone density and image reconstruction of different views. The use of mathematical concepts in some functionality of the system allowed the automatic identification and processing of images parts, eliminating the possibility of human error.
