A Bloom filter is a space-efficient data structure used for concisely representing a set as well as membership queries at the expense of introducing false positive. In this paper, we propose the L-priorities Bloom filter (LPBF) as a new member of the Bloom filter (BF) family, it uses a limited multidimensional bit space matrix to replace the bit vector of standard bloom filters in order to support different priorities for the elements of a set. We demonstrate the time and space complexity, especially the false positive rate of LPBF. Furthermore, we also present a detailed practical evaluation of the false positive rate achieved by LPBF. The results show that LPBF performs better than standard BFs with respect to false positive rate.
engineering systems have become quite complicated in recent days. The requirements of design are complex and it is hard to meet them by considering only one discipline. In this paper, we suggest a hybrid Multi-objecti...

This paper concerns the existence of affine-periodic solutions for perturbed affine-periodic *** kind of affine-periodic solutions has the form of x(t+T)≡Qx(t) with some nonsingular matrix Q,which may be quasi-periodic when Q is an orthogonal matrix. It can be even unbounded but x(t)/|x(t)| is quasi-periodic,like a helical line. for example x(t)=e^(at)(cos ωt, sin ωt), when Q is not an orthogonal matrix. The averaging method of higher order for finding affine-periodic solutions is given by topological degree.

The utilization of expert knowledge to construct Bayesian Network (BN) is one of the key issues of uncertain inference. In this paper the learning procedure of BN is simplified by applying data dependencies in relational database, which help to remove extraneous attributes and build the initial network structure. The final classification model named FM-NB inherits the simplicity of Naive Bayes (NB) and the ability to maintain inter-dependencies among attributes of Tree augmented NB(TAN). The inter-dependencies are expressed by Functional dependencies (FDs) and Local Multivalued dependencies (LMVDs), which relaxed the precondition about attribute sets of Multivalued dependency (MVD) and solved the problem related to conditional independence of Embedded Multivalued dependencies (EMVDs). Experimental results are presented to show the effectiveness and efficiency of the proposed approach.

In this paper, we study the persistence of lower dimensional tori for random Hamiltonian systems, which shows that majority of the unperturbed tori persist as Cantor fragments of lower dimensional ones under small perturbation. Using this result, we can describe the stability of the non-autonomous dynamic systems.
