The discovery and precise manipulation of atomic-size conductive ferroelectric domain walls offers new opportunities for a wide range prospective electronic devices, the emerging field walltronics. Herein, highly stable fatigue-resistant nonvolatile memory device is demonstrated, which based on deterministic creation erasure that are geometrically confined in topological structure. By introducing pair delicately designed coaxial electrodes onto epitaxial BiFeO3 film, center-type quadrant...
The controllable manipulation of polar topological structures (e.g. skyrmion bubble) in ferroelectric materials have been considered as a cornerstone for future programmable nano-electronics. Here, we present the effective creation and erasure bubble states PbTiO3 (PTO) multilayers trigged by mechanical stress light illumination, respectively. It was found that applying atomic force microscope (AFM) tip can induced formation nanoscale domains from initial monodomain state. Moreover, created...
In recent years, there is a surge of research interest in exotic ferroelectric topological states, motivated by their rich emerging physical properties and potential applications nanoelectronic devices. Here, we demonstrate the observation sort complex center-type domain structures, which exhibit quadrant (with polarization pointing to center) texture for an in-plane component cylinder pattern along vertical direction, rhombohedral structured Pb(Zr0.7Ti0.3)O3 (R-PZT) nanoislands. Such center...
Plantar pressure image is an important tool for gait analysis. In the rehabilitation training of stroke patients, it can provide effective quantitative data reference doctors to accurately assess recovery status patients and formulate targeted treatment programs. this paper, a recognition algorithm sensing proposed. Through DBSCAN (Density-Based Spatial Clustering Applications with Noise) clustering minimum circumscribed rectangular algorithm, footprints be located in feature extraction....
Multimodal emotion detection (MED) in interactive conversations is extremely important for improving the overall human-computer interaction experience.Present research methods this domain do not explicitly distinguish contexts of a test utterance meaningful way while classifying emotions conversations.In paper, we propose model, named different contextual window sizes based recurrent neural networks (DCWS-RNNs), to differentiate contexts.The model has four (RNNs) that use sizes.These can...
In this work, we demonstrated that tunable topological domain structures, e.g., center-type domains and skyrmion-like polar bubbles, can be generated at room temperature in high-density epitaxial PbTiO3 nanodots fabricated via the template-assisted tailoring of thin films. These structures manipulated electrically by applying an appropriate bias on conductive atomic force microscopy tip, allowing for writing, erasing, rewriting into nanodot. Moreover, ring-shaped channels are observed around...
Abstract This system used three stage intelligent traffic station subsystems to forecast the path on which vehicle will go. First subsystem can road node adjacented station. Second was designed for bigger area, example city, third larger area between city. A* based orientation calculate shortest path, calculated critical of a large area. The compose dispersed monitor information, dynamic analysis, hierarchical .It played an important role in ITS.
This paper uses tree structure to evaluate the similarity between mathematical formulas. Firstly MathML is used describe formula, then file turned a and calculation of formulas' based on structure. However, there two difficulties in comparing: firstly large time cost comparing, our "fast sub string extraction" method reduce largely; secondly how get satisfying result, here calculated by backdating "lever importance", has result compared with those methods which ignore lever information.
Ontology matching is an important method of Web service matching. Because ontology has meaning, based on can return more result. This paper firstly analyses several methods matching, then uses Galois and vector space to implement ontology's Experiment shows it great advantage than the keyword.
IEEE 802.11 b and g standards, which are compatible with each other, combined to provide higher-performance wireless communication more options of data rates. In order meet the upgrading demands standards other using DSSS OFDM as pivotal algorithms physical-layer parts, a SOC (or ASIC+DSP) solution is used realize baseband system. The paper firstly introduces features b/g PHY, then gives architecture layout BX501, chip designed taped out in SMIC 0.18-micron technology. also presents testing...
The governance model of "blockchain + digital rights" has attracted wide attention due to its characteristics decentralization and high efficiency.However, the problems potential risk under new technology should also be paid to.Based on blockchain, there are four risks technical levels rights platformoperational effectiveness, supervision, privacy security, smart contract.From perspective game theory, a tool conduct hierarchical analysis, targeted control strategies for each level can...
OGC web service provides an important method for GIS data sharing and interoperability. But it is difficult to find suitable service, how get appropriate has become a serious problem. We discuss the of finding services, filtering unsuitable services invoking services. To WFS WMS several search engines' source code are used, then keywords in found page analysis, SVM based on importance factors used. By this way, automatic. Practice shows Web by can satisfy user better.
The GIS web services are difficult to be found and two many need administered. This paper uses agent solve this problems. Firstly, it puts forward the structure of sharing system, gives model collaborating method agents. Then presents communication between agents in service. Experiment shows is feasible. Lastly introduces a subsystem ITS as sample.
When we search web service, often get many results that don't satisfy, or too less to be choose from. This papers uses generalized list concept lattice realize service matching, and it explains detailedly the princple. Experiments show this method can much better than matching based on keyword normal lattice.
The aim of this paper is to investigate the multiple attribute decision making problems with triangular fuzzy information, in which information about weights completely unknown, and values take form numbers. In order get weight vector attribute, we establish an optimization model based on maximum deviation, by can be determined. Then, traditional TOPSIS method, calculation steps for solving decision-making unknown are given. weighted distances between every alternative positive ideal...
