Semantic parsing of large-scale 3D point clouds is an important research topic in computer vision and remote sensing fields. Most existing approaches utilize hand-crafted features for each modality independently and combine them in a heuristic manner. They often fail to consider the consistency and complementary information among features adequately, which makes them difficult to capture high-level...
This paper introduces the entire roadmap and detailed research methods of our NSFC project. A three-stage roadmap is proposed for energy store application of marine power station, and called upon to solve the key issues of health feature rapid extraction and modeling for battery pack. Efficient numerical modeling, rapid ICA and EIS testing and degradation of key features investigating makes the acquirement...
The performance of data-intensive parallel jobs is often constrained by the cluster's hard-to-scale network bisection bandwidth. Previous solutions do not consider inter-job data dependencies and schedule jobs independently from one another. In this work, we find that aggregating and co-locating the data and tasks of dependent jobs offers an extra opportunity of data locality that can help to greatly...
There is great potential for the application of Microaerial vehicles (MAVs) in the field of civil and military. Robust trajectory tracking control ability is fundamental for flying tasks. However, MAV is an under-actuated, nonlinear and strong coupling system and it usually endures frequent disturbances while flying. These factors make precise trajectory tracking control of MAV very difficult. The...
Detailed information of the capacity fade mechanisms can be very beneficial for the prognostics and health management (PHM) study of lithium-ion batteries. This paper reports a novel capacity fade analysis method. The parameter degradation of multi-physics model is achieved, and the three main factors of capacity fade is quantitatively calculated by using the obtained parameters. The results show...
A multi-physics model is developed based on P2D model, including the electrochemical part, thermal part and the temperature distribution. It can simulate the physical and chemical phenomena from the scale of the active particles to the scale of whole battery. The charging optimization is also investigated, two internal characteristics, which can only be calculated by the proposed model, are treated...
We present the design, fabrication and characterization of multiple micro-pocket lid arrays used in live single cell metabolic analysis. In previous work we reported a platform for quantifying single cell oxygen consumption rates realized using a fused silica deep wet etching process. Here we extend that work to a dual-depth wet etching process for microfabrication of multiple sensor trapping (MST)...
Ultrasmall monodispersed Au nanoparticles are synthesized using a gas-liquid interfacial plasma (GLIP) technique combined with introduction of ionic liquid and oleylamine under low gas pressure. The morphology and particle size of the synthesized nanoparticles are characterized by UV-vis, TEM, SAED and XRD.
We consider the design of distributed strategies that allow multiple secondary users to opportunistically access multiple unslotted Markovian channels with unknown parameters and tight collision constraints, a challenging problem setting that has not been well addressed by existing work. An optimal strategy would strike a balance among exploration, which is to measure all the channels to identify...
In this article, Li+ initial inserted rate and stoichiometric window of electrode materials in Li-ion batteries are identified using Multi-Objective Genetic Algorithm (MOGA). The article is motivated by the problem of fitting both the OCP model and incremental capacity analysis (ICA) curve, which comes from OCP curve and has higher parameter sensitivity, of batteries to those experimental data. A...
With the development of micro/nano electronic technology and the miniaturization of IC (Integrated Circuit) packaging, the interfacial characteristics of the nanoscale interface structure in IC packaging become more and more serious on the whole performance of IC or devices. The aim of this article is to put forward a hybrid scale method to evaluate the interfacial thermal characteristics of the Cu/Al...
To explore the effect of oil film temperature on hydro-viscous drive (HVD), a 3D physical model of the oil film was established. According to the principle of computational fluid dynamics (CFD), the model was solved by using finite volume method (FVM), and a HVD test-bed was developed to verify the theoretical analysis. The results show that the relationship between the temperature and the time is...
The three-dimensional model of the slide block of the YQK-1250 hydraulic machine was established in this article by solidworks, and then was imported into Ansys. The modal analysis was completed with the method Lanczos. And got the proper frequency and vibration mode. Through the analysis of their structure performance under the various vibration modes, got the dynamic character. After that, the character...
In this research, authors have attempted to adapt artificial soil system to treat high-concentration COD restaurant wastewater (RWW). The capability of treatment system is 80 tonnes per day (t/d). After two months of experimental operation and refinement, the system produced the final effluent quality as follows: CODCr = 140.1 mg/L, BOD5 = 99.8 mg/L and SS = 46 mg/L, which greatly reduced the concentration...
Maintaining a common notion of time among communicating nodes in mobile multihop networks is crucial to the correctness of many distributed real-time applications such as target tracking, data fusion, and environmental monitoring. Achieving both synchronization accuracy and efficiency (in terms of communication and energy overheads) are important goals of a time synchronization mechanism. While these...
A novel element FEdge, containing geometric and textured information, is proposed for geometry and texture coupled generalization of urban buildings, in relation to urban legibility of roads, districts, and landmarks. In order to take into account geometric characteristics of different footprints better, we cluster building footprints by creating their positive buffers to preserve roads at desired...
Product data management system is one of the most important components of enterprise information construction. The concept and characteristics of product data management (PDM) has been introduced. In order to research the disadvantages of a company's data management system (NAIRC), NAIRC-PDM system based on PDM was been build on the traditional product data management system structure.
NO adsorption over powder activated carbon in a fluidized bed reactor has been studied. NO could be adsorbed by fluidized powder activated carbon. This study showed that lower reaction temperature gave more amount of NO adsorption. When no oxygen was present, the amount of NO adsorption was little. With increasing oxygen content, the amount of NO adsorption increased. Although NO2 was not detected...
Autonomous management of a multi-tier Internet service involves two critical and challenging tasks, one understanding its dynamic behavior when subjected to dynamic workload and second adaptive management of its resources to achieve performance guarantees. In this paper, we propose a statistical machine learning based approach to achieve session slowdown guarantees of a multi-tier Internet service...
Rigorous new regulations in coal-fired pollutants emissions by power plant have caused new demands for electrostatic precipitator (ESP) technology. The study was inspired by the requirement to use cheaper flexible polypropylene fiber and Terylene fabrics as substitutes for typical collection electrodes to save energy and structural materials, and to solve the adverse impacts caused by wet flue gas...
