Much importance is attached to the weights on the edges in a network, but in actual fact what makes up a network is both the nodes and the edges linking up the network. It is therefore pertinent to investigate the effects and importance of the weights attributed unto the nodes in a network as well as the weights on the links of such networks as they both play important roles in determining the prominence...
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...
A recursive least-squares (LS) state-space identification method based on the QR decomposition is proposed for non-uniformly sampled-data systems. Both cases of measuring all states and only the output(s) are considered for model identification. For the case of state measurement, a QR decomposition-based recursive LS (QRD-RLS) identification algorithm is given to estimate the state matrices. For the...
In a graph or a network G = (V, E), a set S ⊆ V is a 2-packing if ∀i ∊ V : |N[i]∩S| ≤ 1, where N[i] denotes the closed neighborhood of node i. A 2-packing is maximal if no proper superset of S is a 2-packing. This paper presents a safely converging self-stabilizing algorithm for maximal 2-packing problem. Under a synchronous daemon,...
To address the need for an efficient and effective biomedical information retrieval system, this paper presents an ontology-graph based web tool, G-Bean (graph based biomedical search engine), for searching biomedical documents from the MEDLINE database. This search engine uses an ontology-graph based query expansion technique to expand the initial query with additional query terms and/or more specific...
Atmospheric-pressure room-temperature plasma jets are commonly used in plasma medicine, nanotechnology, as well as surface and materials processing. Most of the applications require room-temperature operation while completely avoiding the glow-to-arc transitions. To meet these requirements, the atmospheric plasma jets are usually sustained in noble gases. However, this is very challenging for the...
Based on the orthogonal projection approach, a few closed-loop subspace identification methods have been developed recently in the literature. To guarantee consistent estimation of these methods against measurement noise, this paper analyzes the rank condition for performing the corresponding singular value decomposition (SVD) involved in deriving the extended observability matrix and the lower triangular...
Art historians have long observed the highly characteristic brushstroke styles of Vincent van Gogh and have relied on discerning these styles for authenticating and dating his works. In our work, we compared van Gogh with his contemporaries by statistically analyzing a massive set of automatically extracted brushstrokes. A novel extraction method is developed by exploiting an integration of edge detection...
Theoretical model of symmetrical constrained damping structure for railway wheel is established based on complex stiffness method. Four parameters are related to the noise-restraint performance of wheel with damping treatment, which are the thickness of constrained layer, the thickness of damping layer, the loss factor and the complex shear module of damping material. Optimal calculation in the frequency...
