Emerging Information-Centric Networking (ICN) architectures seek to optimally utilize both bandwidth and storage for efficient content distribution over the network. The Virtual Interest Packet (VIP) framework has been proposed to enable joint design of forwarding, caching, and congestion control strategies within the Named Data Networking (NDN) architecture. While the existing VIP algorithms exhibit...
Gearbox fault signal has non-stationary and non-linear features, conventional spectral analysis methods all have their own limitations. This paper presents the method of combining empirical mode decomposition (EMD) and cepstrum analysis, and develops a gearbox fault detection system based on LABVIEW. Practical tests show that each signal could be decomposed into a number of intrinsic mode functions(IMFS)...
For general multi-hop queueing networks, delay optimal network control has unfortunately been an outstanding problem. The dynamic backpressure (BP) algorithm elegantly achieves throughput optimality, but does not yield good delay performance in general. In this paper, we obtain an asymptotically delay optimal control policy, which resembles the BP algorithm in basing resource allocation and routing...
Bayesian Network is one of the most efficient and reliable method in data mining, and Bayesian Network structure learning is a key link in the process of Bayesian Network research. Aiming at the problem of the classic Hill-Climbing algorithm is easy to fall into local optimum and low in efficiency, establishing the Most Weight Supported Tree by calculating the mutual information, and combining the...
The negative database (NDB) is a new technique for privacy preserving and information hiding. It hides information by storing the complementary set instead of the original data. In order to protect the hidden information, NDBs should be hard-to-reverse. In this paper, we propose the Khidden algorithm for generating hard-to-reverse NDBs (called Khidden-NDBs). The K-hidden algorithm could be controlled...
The home health care crew scheduling and routing problem with stochastic service times is studied in this paper. A stochastic programming model with recourse is constructed to describe the problem. The approximate formulation for the expected penalty for late arrival at a customer is obtained and analyzed. According to its features, the problem is transformed into a classical set partitioning problem...
This paper proposes a new design of gesture controlled MP3 player method based on triaxial accelerometer MMA7260, and in program applying the matching algorithm —using shaking times to match the operation instructions. The experimental results shows that the design can make MP3 player play, stop, play back, play forward and so on.
The open capacitated arc routing problem (OCARP) is defined and considered in this paper. The OCARP differs from the classic capacitated arc routing problem (CARP) because the vehicles are not required to return to the depot. The OCARP seeks to find a set of minimum cost open routes that serve task arcs of a given graph, subject to vehicle capacity and travel distance span restrictions. A mathematical...
