The minimum Steiner tree theory is the basis theory of global shortest path. It is one of the classic NP-hard problems in nonlinear combinatorial optimization. A visualization experiment approach has been used to find Steiner points and the system shortest path named Steiner minimum tree. However, the obstacles must be taken into consideration in some problems. An obstacle-avoiding Steiner minimal...
Content addressable memory is a novel storage device that can save data in its cells, which could be read, written and searched on the basis of their contents. This paper presents Memristor content addressable memory (M-CAM) structures that are formed of M-CAM cells, which compare searched data and stored data then give a cell output signal to be kept in its comparator. After the comparison in each...
To identify and eliminate the product's early failures with the lowest cost and the best effect, this paper proposes a HASS profile research method based on computer simulation technology. Firstly, the flow and implement steps are introduced, then take the solder joint as an example, to show the application of the computer simulation method in a specific way, finally, summarizes the application prospect...
Attribute reduction and decision rules are the key questions of rough set theory. Rough sets has developed to quite a matured level in a single universe of research, however, there are nearly no researches about rough set theory of dual-universe based on multiple information system. In response to this, this paper puts forward reduction methods of rough sets based on dual-universe, decision rules...
The multiwavelet property of Legendre wavelets is obtained by multiresolution analysis of multiplicity. Taking advantage of the translation property of Legendre wavelets, the extended Legendre wavelets, defined on the interval (-r, r), is achieved through a translation operator transformation on Legendre wavelets. This paper considers the multiwavelet property, orthogonality, symmetry, continuity...
According to the fragile watermarking theory and insecure computer network, the integrity authentication scheme of biometric image based on singular value decomposition (SVD) is proposed for remote users via insecure computer network. We make good use of singular values of singular value decomposition (SVD) of biometric image to check the integrity of biometric image. To make authentication data,...
