摘要：
This paper is concerned with the reachable set estimation problem for discrete-time switched singular systems. Our goal is to check whether there exists a bounded set that contains all the states trajectories under zero initial conditions. First, a sufficient condition is established in terms of linear matrix inequality (LMI) to guarantee that the reachable set of discrete-time switched singular system is admissible and bounded by the intersection of ellipsoids. Second, two special cases of discrete-time switched singular systems is studied. Finally, an numerical example is provided to demonstrate the effectiveness of the proposed methods.
摘要：
An algorithm of task scheduling with data dependent is proposed. The algorithm consists of two steps: determining the priority of tasks and selecting the resources for tasks scheduling. In the step of prioritizing tasks, a new definition of task rank is introduced, which improves the traditional definition by taking the sum instead of the maximum of the upper and the lower ranks, therefore better representing the residual load of tasks in the workflow. In the step of selecting resources, a new method based on the fastest computation time is designed. In addition, the selection of critical path used in task scheduling depends on the new definition of task ranks, and comparison is given with the traditional methods. Finally, we analysis and compare the results of several task scheduling methods and prove that our algorithm outperforms better than the existing algorithms.

摘要：
The development of 3D technology makes 3D audio and video technology become a research hotspot. Most of the existing 3D audio technologies reconstruct the original sound field at the center point, which makes the reconstruction effect at the center point is the best, but the reconstruction effect at the non-central point is poor. In order to solve this problem, a non-central pint 3D sound field reconstruction method is presented. The proposed method finds the location of virtual loudspeakers by constructing a virtual sphere. The signals of virtual loudspeakers are solved by traditional method. By keeping particle velocity at the non-central point constant, the signal of real loudspeaker can be obtained from the signal of virtual loudspeaker. Compared with traditional methods, the effect of the proposed method is proved by simulation experiments.

摘要：
The emission of greenhouse gas (GG) is a prime cause of global warming. But the emission reduction may lower economic growth rate. Since different countries have different industrial structure, the criteria of proper emission reduction is important for every country. In this paper we consider four GGs including carbon dioxide, nitrogen oxides, methane and nitrous oxide. Based on Gaussian hybrid model, we make clustering analysis for 31 European countries in 2017. The empirical analysis reveals that clustering membership becomes more distinct compared with k-means approach. In addition, the results show that 31 countries are grouped into four classes and Germany and France in the emissions of GGs are higher than others.
摘要：
The recommended algorithm is one of the most popular applications of today. Firstly, the original data is cleaned and processed, and then the association rules model and user value analysis model are established in this paper. Secondly, a Apriori algorithm is used to analyze the relationship between user history access records and the user group of K-means algorithm is used to divide value. Finally, the experimental results show that the results of the output of the association rules and the clustering analysis of the user value have some reference significance.
摘要：
Prostate segmentation from MRI image is a challenging task due to the appearance variations of different patients and in particular feature and density heterogeneity within a same image. To address these challenges, we propose a collaborative learning based model to adaptively choose the optimal features from a set of feature candidates to improve prostate boundary delineation. In our method, on the basis of weighted multi-view collaborative clustering, our proposed new ranking and selection scheme automatically determines the unique feature for optimally contouring individual image regional sectors that exhibit density inhomogeneity and feature variations. The approach was tested on prostate MR scans without endorectal coil from PROMISE12. The segmentation accuracy was evaluated with respect to five most often used evaluation criteria in terms of spatial volume overlap and shape similarity. The experimental results demonstrated that our proposed method based on collaborative learning model outperformed graph-based algorithms and the multi-view clustering models.
摘要：
Load balance problem has become a research hot spot problem of distributed computing field, whose objective is to ensure that each physical resource is allocated efficiently and fairly. As a typical distributed computing environment, the load balance of resource allocation in cloud computing environment is implemented by the live migration of virtual machines. A virtual machine resource provision genetic algorithm based on load balance, LB-GA is presented. Combined with the advantages of genetic algorithm, the proposed algorithm has an excellent outcome in balance of resource allocation. The simulation experimental results show that LB-GA can not only get fewer virtual machine migration amount, but also can implement load balance of cloud resource allocation. In the end, an application scenario of load balance in cloud computing environment is constructed to demonstrate the importance of our algorithm.

摘要：
The decision tree is an important data mining method for classification. Granular computing has been applied to the decision tree, then a new decision tree based on the classification preference ratio of attribute is proposed. This decision tree is a hierarchical granularity tree. In information systems, each condition attribute divides the domain into several parts of a granular space. In the granular space, the classification preference ratio is used to describe the condition attribute. The classification preference ratio of every condition attribute is computed, and then the maximum attribute is chosen to divide the domain. According to different values of the attribute, the sample set is divided into several subsets. Each subset is a node or branch of the decision tree. If all the objects in a node are the same class, this node is a leaf node without further division. Otherwise, the node is not a consistent node. Above process of division will be repeated for all inconsistent nodes until all nodes become leaf nodes. Now the decision tree is finished. An example is given, which shows that the algorithm is feasible.

This paper deals with the problem of reachable set. bounding for interval time-varying delay system with disturbances. A generalized reciprocally convex combination lemma and a new Lyapunov-Krasovskii functional (LKF) are given to obtain the delay-dependent criterion.
