Semantic Web plays an important role in the of future. The RDF data is key component which establishes basis Web. In this paper, we conlude usages and possible problems blank nodes with detailed analyses applications semantics graphs. Give special attentions to inconsistency between SPARQL nodes. Employ concept “lean graph” pre-process operation, propose a method using entailment relations graphs transformation from URI references eliminate graphs, give theoretic background support method....

XML digital signature is an important specification of W3C, while most implementations the signatures are based on overall document at present. This paper mainly describes a method and process for resource fragment. The available effective through practice by JDK 6.

A two-dimensional three-component (2D/3C) electron magnetohydrodynamic (EMHD) model is implemented to investigate the linear behavior of collisionless tearing modes in slab geometry. Owing nonuniformity thermal pressure and plasma density, diamagnetic drift Biermann battery effects are involved. The structures, growth rate, real frequency analyzed with a thin current sheet inertia scale. ratio total equilibrium can notably promote mode EMHD. More numerical results then show that effect...

How to ensure the security of digital image information is a difficult and hot problem. This paper presents new scrambling encryption algorithm based on chaotic sequence. The utilizes good features sequence related cryptographic properties, such as pseudo-random, sensitivity initial conditions aperiodicity. use logistic mapping confusion location pixels in image. Simulation experimental result shows that this has performance, large space keys, computes simply rapidly with high security.

In this paper, a resistive magnetohydrodynamics model is applied to study the effect of sawtooth driven on classical/neoclassical tearing modes in tokamak plasmas. forced reconnection, considered as boundary disturbance for m>1 and causes islands growth m/n = 2/1 3/2 through toroidal coupling. Theoretical numerical analyses show that linear by precursors mode coupling, while differential rotation has great both nonlinear development modes. It believed can be suppressed control radio...

The W3C Open Annotation Community Group’s (OA) Data Model is emerging as a standardized Web Model. We argue that friendly interactive visual user interface for OA based annotation tools, which largely on an effective model, plays essential role in the usability of tools. In this paper we propose Interactive Visual User Interface Annotations (or simply IVUIM4OA), allows annotating to dynamically transform data into representation and interactively manipulate objects modify or produce new one....

Based on the magnetic field configuration of Chinese First Quasi-axisymmetric Stellarator (CFQS) device, three types orbits such as passing orbit, blocked trapped and localized orbit are simulated using Boris algorithm. Also, orbital topology, transition, loss characteristics these particles under different initial conditions studied in this paper. It is found that there exists a transition from to due small continuous helical ripples. This phenomenon analyzed follows: we define angle...

<sec> The fast ion transport associated with resonant magnetic perturbation (RMP) contains rich physical spanning single particle motion of and plasmas response physics RMP their interaction. Full numerical simulation considering such ingredients should be performed in a long run for clarifying the underlying features confinement RMP. Thus, appropriate application is not only to avoid detrimental effects but also serve as an actuator exert targeted control over energetic profile. To...

Abstract. A method suitable for indoor complex semantic query considering the computation of spatial relations is provided According to characteristics space. This paper designs ontology model describing space related information humans, events and Indoor objects (e.g. Storey Room) as well their meet query. The concepts are used in IndoorSPARQL language which extends SPARQL syntax representing querying And four types specific primitives query, "Adjacent", "Opposite", "Vertical" "Contain",...

The 2D electron-magnetohydrodynamics (EMHD) dominant tearing mode in an electron-skin-depth-scale current sheet (ECS) is further studied. resistive diffusion proved to be insignificant at the scale. Electron inertia leads expansion of “inner region” as well a wider saturation island and invalidity boundary layer approximation. unstable index Δ′ thus decreases dramatically from that classical asymptotic theory. As for nonlinear evaluation, inverse spectral cascade flattening m = 0...

The benefits of the development continued social interactions among individuals in an educational environment have been well documented literature. Nonetheless, few instructional design strategies are available to instructors for Web-base learning environment. basing on interaction theory and corresponding activities that imported into our previous system introduced Theoretical foundation these has discussed this paper.

Multimodal Emotion Recognition (MER) has recently become a popular and challenging topic. The most key challenge in MER is how to effectively fuse multimodal information. Most existing works may fail consider the cross-modal interaction information for MER. To address this problem, paper proposes new framework based on audio text by using Hybrid Attention Networks (MER-HAN). proposed MER-HAN combines three different attention mechanisms such as local intra-modal attention, global inter-modal...

Chaos system is a kind of complicated, nonlinear dynamic system. The complexity, pseudo-random and sensitivity to initial conditions chaotic sequence have close relationship cryptographic properties. We analyze the typical system-logistic mapping. On basis this analysis, we present novel Chinese character encryption algorithm based on logistic This new methods computes simply rapidly with high security. results are described in end.
