The morphology of glands is the main basis of colon cancer diagnosis and accurate segmentation of glands from histology images is a prerequisite for correct clinical diagnosis. A gland segmentation method based on Segnet is proposed in this paper. First, the Warwick-QU dataset is used and augmented for training Segnet. Second, the network parameters are optimized according to the training results. Finally, the trained Segnet is used to perform segmentation test on both Parts A and B of Warwick-QU. The results show that the presented method achieves segmentation accuracy of 0.882 on Part A and 0.8636 on Part B, and shape similarity 106.6471 on Part A and 102.5729 on Part B, respectively. Compared with the existing methods with respect to the same dataset, our method reaches the highest accuracy on whole.

This paper is concerned with the tracking control problem for the closed single spin-1/2 quantum ensembles. Based on the Liouville-von Neumann equation, mathematical model of dynamics for single spin-1/2 quantum ensembles are formulated as a bilinear form with states evolving on Bloch sphere. An associated matrix Lie group equation describing transfers from the initial state being an identity matrix is naturally introduced. The tracking problem for the system in question is transformed to a stabilization problem such that the control techniques are able to be used. In order to deal with the tracking problem, the Lyapunov-based feedback design method is employed to obtain the control such that the dynamics of system can converge to the reference trajectory.

This paper considers the problem of adaptive output feedback prescribed performance control for a class of switched nonlinear systems with time-varying delays. The radial basis function neural networks are employed to approximate the unknown nonlinear functions. In order to estimate the unmeasured system states, an observer is designed. It is shown that all signals of the closed-loop system are bounded and the tracking error satisfies the prescribed performance. Finally, an example is presented to demonstrate the effectiveness of the proposed method.

In this paper, we expect to design a multi-objective robust filter for fuzzy singularly perturbed systems (SPSs) with Markov switching. By utilizing the Takagi and Sugeno (T-S) fuzzy model and the Markov jump model, both the nonlinearity and the sudden changes in the parameters or structures are considered in the description of SPSs. Based on some acquired conditions, the final filtering error system can be assured stochastically stable with a prescribed dissipative performance index. Finally, the filter gains can be gained by solving these conditions.

In this paper, we propose a quantized feedback control approach based on event-triggered observer. First, according to the characteristics of event-triggering mechanism and observer, an event-triggered observer is put forward to estimate the unmeasured states. Next, we introduce quantizer and controller to quantify data and construct closed-loop system respectively. In this framework, besides the observer, quantizer and controller are only updated at the event-triggered sampling instants so that it can reduce the computational effort and sampling frequency. Moreover, the condition in terms of linear matrix inequalities is provided to ensure the closed-loop system as well as the observer error system and quantization error system asymptotic stability under the event-triggered strategy. Finally, the simulation example is given to illustrate the proposed method.

For a multiple multicopter system, the increase in the number of multicopters may lead to severe trap problems. These will abort missions, crash multicopters, or even injure people. To solve the trap problem and guarantee the mission of each multicopter, an Air Traffic Management (ATM) system should build. In this paper, a local decentralized air traffic protocol for multiple multicopters is proposed to solve the trap problem and complete a series of tasks in a local low altitude airspace. Based on the Artificial Potential Field (APF) method, the protocol is designed in the form of a state machine to coordinate the motions of multiple multicopters. Finally, some simulations are performed to show the effectiveness of the proposed protocol in a case study.

In this paper, the problem of state estimation for nonlinear discrete-time switched system is investigated. At first, the nonlinear switched system is represented as Takagi-Sugeno (T-S) fuzzy switched system, i.e., T-S fuzzy models are employed to approximate nonlinear parts. After that, a mode-dependent Luenberger-type observers under synchronous switching is employed to estimate the state of discrete-time T-S fuzzy switched system. By constructing multiply Lyapunov functions (MLFs) and common Lyapunov functions (CLFs), several sufficient conditions are established, in which the actual states of the estimated system under constrained switching (average dwell time (ADT) and mode-dependent average dwell time (MDADT) switching) and arbitrary switching can be tracked by the state of received observers, respectively. Finally, to testify the effectiveness of the proposed solution, one numerical example is provided.

Epidemic spreading and information diffusion are two fundamental types of dynamical processes on complex networks. We present the analysis of the interrelation between two processes: one is the spreading of epidemics, the other is the information diffusion which conclude individual sensitivity in multiplex networks. Then we propose a UADU-SIS model of multiplex networks which adopt information diffusion model-UADU and epidemic spreading model-SIS to describe upper and lower layer networks respectively. By using the continuous time Markov process, the analysis reveals the situation of the incidence of the epidemics and allows to capture the evolution of the epidemic threshold. The threshold depends on the topological structure of the multiplex and the interrelation with the awareness process. The research shows that the threshold of Epidemic spreading is not only related to the structure of social network, but also associated with the individual sensitivity and the information diffusion in the communication network.

Multiscale science is an emerging scientific field, and the multiscale computing methods, such as coarse-graining and empirical mode decomposition (EMD), have received increasing attention. Heartbeat Time Series are rich in multiscale information, but the traditional analysis methods only consider them on the single scale, which is not conducive to a comprehensive understanding of the dynamics of the system. Meanwhile, poincaré plot is widely used in the analysis of heart rate variability (HRV) which quantifies the variability of the series, but without probability distribution. To facilitate multiscale visual analysis of RR intervals series, we introduce enhanced EMD multiscale poincaré plot (EEMP). We first employed EMD to create a family of intrinsic mode function (IMF), each of which represents the characteristic time scale embedded in the series. Next, multiscale poincaré plots are constructed for each scale. Finally, to display probability distribution intuitively, color labels are added to each point using kernel density estimation to exhibit the normalized frequency. We illustrated the EEMP approach on RR intervals time series from normal subjects comparing with atrial fibrillation (AF) subjects and congestive heart failure syndrome (CHF) subjects to analyze the dynamics of different physiology states visually. In the future, this generalized approach may be used well in other types of time series.

Compared to permanent magnetic brushless DC machine with trapezoidal back EMF waveforms (BLDCM), permanent magnetic synchronous machine with sinusoidal back EMF waveforms (PMSM) has superior performance. To enhance performances of BLDCM, this paper adopts a new type oriented vector control strategy. Contrary to traditional rotor-flux oriented vector control in PMSM, the new control strategy takes back EMF as the oriented vector for improving the capability of maximum torque per ampere (MTPA) of BLDCM and reducing the torque ripple [1]. Also, a Space vector PWM modulation (SVPWM) based on “120° conduction mode” is utilized for three-phase bridge inverter [2]. Combined the oriented strategy aforementioned with proposed SVPWM method, a new control system is constructed. Simulation validates effectiveness of this new control scheme.
