Ait-Sahalia-Rho model;Boundedness;Convergence in probability
摘要：
The Ait-Sahalia-Rho model is an important tool to study a number of financial problems, including the term structure of interest rate. However, since the functions of this model do not satisfy the linear growth condition, we cannot study the properties for the solution of this model by using the traditional techniques. In this paper we overcome the mathematical difficulties due to the nonlinear growth condition by using numerical simulation. Thus we first discuss analytical properties of the model and the convergence property of numerical solutions in probability for the Ait-Sahalia-Rho model. Finally, an example for option pricing is given to illustrate that the numerical solution is an effective method to estimate the expected payoffs.

摘要：
A path following control problem of discrete-time autonomous underwater vehicle (AUV) with input delay is studied. For solving the time-delay in control system, an neural network (NN) predictive control method is introduced. Since the velocities are very difficult to be accurately measured, here output feedback method is employed to overcome this problem. The stability analysis is given by Lyapunov theorem. Simulation results show the effectiveness of the proposed control strategy.

The original content was copied without attribution (including appropriate references to the original author(s) and/or paper title) and without permission. “Optimal online deterministic algorithms and adaptive heuristics for energy and performance efficient dynamic consolidation of virtual machines in Cloud data centers” by Anton Beloglazov and Rajkumar Buyya in Concurrency and Computation: Practice and Experience, October 2011, pp.1397-1420 “Energy-aware resource allocation heuristics for efficient management of data centers for Cloud computing” by Anton Beloglazov, Jemal Abawajy, and Rajkumar Buyya in Future Generation Computer Systems, May 2011, pp.755-768 Cloud computing provides a kind of dynamic and scalable service on demand. However, clouds consume huge amounts of electrical energy. Meanwhile, delivering the negotiated QoS defined as Service Level Agreement (SLA) to users is necessary. A virtual machine placement strategy based on the equilibrium between energy and SLA is proposed. Aiming at dynamical changes of application workloads, an adaptive placement strategy RLWR based on robust local weight regression is presented, which decides the overload time of hosts dynamically according to the historical resource occupation of application workload. Then, two virtual machine migration selection algorithms, MPM and MNM are presented. The migrated virtual machines are deployed using bin-packing algorithm PBFDH. Contrasting to static algorithms such as STH, MPA and DVFS, virtual machines are not only deployed on fewer hosts in our algorithm, which promotes energy efficiency, but the load prediction can bring high-reliable QoS delivery and avoid overmuch SLA violations. Experimental results show that our strategy has an obvious effect on decreasing SLA violation under ensuring energy efficiency.

摘要：
Convolutional Neural Network (CNN) has achieved remarkable progresses in hyperspectral image (HSI) classification. However, how to effectively implement spatial context that has been demonstrated to he useful for HSI classification is still an open issue. Existing CNNs for hyperspectral classification are restricted into a small scale due to small-scale inputs and limited training samples. Therefore, in this paper, two different methods are proposed to integrate both spatial context and spectral signature into CNN based HSI classification: I). fixed kernels in which weights are determined by prior information (e.g., mean, mean and standard deviation of pixels in a spatial neighborhood) and Gaussian kernel; 2). learnable kernels in which weights are learned from training samples, i.e., 2D learnable kernel, 3D convolutional kernel, and 2-Layer kernel. In the successive CNN for classification of HSI, dropout and batch normalization are also utilized to improve the classification performance of hyperspectral images under small sample conditions. Experimental results on two widely used HSI datasets demonstrate that integrating spatial context into a small scale CNN is useful to improve classification performance. It is also observed that fixed kernels are generally effective than learnable ones to explore spatial context, particularly for the cases with a small number of training samples.

摘要：
This paper deals with the problem of sliding mode control (SMC) for a class of singular systems with time-varying delay. A sliding mode controller is designed such that the singular system is exponentially admissible and in finite time the trajectory of singular system can be driven onto the sliding surface. By constructing a Lyapunov-Krasovskii functional and using the free-weighting matrix approach, the results on exponential stabilization are obtained in terms of strict linear matrix inequalities (LMIs). The derivative of the time-varying delay does not require to be smaller than one is a advantage of this paper. Finally, the effectiveness of the proposed main results is illustrated by a numerical example.

摘要：
Meeting users’ Quality of Service (QoS) requirements is a key problem of tasks scheduling in cloud computing. A cloud tasks scheduling algorithm CTS_QoS based on maximal QoS satisfaction and minimal QoS distance between tasks and resources is presented in this paper. Under meeting maximal QoS satisfaction of user’s tasks, CTS_QoS can select the resources with minimal QoS distance to map. Experimental results show that though CTS_QoS cannot guarantee a high resource utilization, it can gain users’ QoS satisfaction maximization.

segmentation;active contour;smoothing parameter;edge information
摘要：
Active contour model is one of the most popular image segmentation frameworks. Conventional active contour model requires the empirical adjustment of smoothing parameter in energy functional and the smoothing parameter for active contour is a challenging problem. In this paper, we propose an automated adjustment method for the smoothing parameter in region-based active contour models and thus a full automated segmentation method is obtained. In proposed active contour model, the region term is the same as that in traditional region-based active contour model, whereas the prior term in traditional region-based active contour model is substituted by gray statistic of edge image on the contour. Thus the evolution of contour has the same iteration form as that in traditional region-based active contour model. But a driving force from the edge information takes the role of smoothing term and the adjustment of smoothing parameter is avoided. Experimental results show the proposed model can obtain segmentation quality comparable to the those obtained by traditional region-based active contour model, without the cumbersome trial of smoothing parameter.

摘要：
These online-teaching database systems are generated from online transactions, emails, videos, audios, images. They are stored in databases grow massively and become difficult to capture, form, store, manage, share, analyze and visualize via typical database software tools. The adventure of large amount of data and real-time requirements presents great challenges using traditional desktop computers. In this paper, to tackle the specific problem with a critical requirement of 10ms for whole data processing pipeline, we proposed a high performance embedded system as opposed to personal computer. Peripheral Component Interconnect (PCI) for data transferring from computer to Field Programmable Gate Array (FPGA) is proposed to solve the problem, and a custom-designed dual-port dual-channel RAM to realize simultaneous data exchange and data processing which was implemented using a 6-core Digital Signal Processor (DSP). The hardware system was designed and tested the performance of individual modules as well as the integration of them as a whole. We reported a total time using such pipeline of 7.5ms, meeting the critical requirement and demonstrating its feasibility in practical application.
