While EVI and LAI are the most widely used vegetation parameters which can be used for remote sensing phenology extraction, this paper aims at assessing the differences of phenology information extracted from EVI and LAI time series and exploring either EVI or LAI time series performs well for all vegetation types over a large scale. To achieve this, GLASS-LAI phenology product(GLP) was generated...
This paper proposes a novel Continuous Quantum Immune Clonal Optimization (CQICO) algorithm for thermal optimization on an 117kW high speed permanent magnet generator (HSPMG). Via mixing the Quantum Computation into the Immune Cloning Algorithm, the new algorithm is benefited with better population diversity, higher global searching ability, and faster convergence which approved by simulation results...
This paper highlights the armature design considerations for an ultra-high speed PM generator (UHPMG) used in turbine applications considering the efficiency and manufacturability. Via the transient electromagnetic fields analyzing, the electromagnetic performance of a 5 kW UHPMG is investigated, and the obtained results are verified by the experimental data on the prototype in same operating. Then,...
2D-video-based gait recognition techniques have been studied for decades, but there are still many challenges, one of which is the robustness against the variation of view angle. In this paper, the second generation Kinect (Kinect V2) is used as a tool to establish a 3D-skeleton-based gait database, which includes both 3D information of the skeleton joints and the corresponding 2D silhouette images...
Figure 2 shows the observed gap fraction and gap size distribution along with the sampling line. According to the algorithms of LAIcc, LAIlx and LAIpl, the results are obtained using the observed gap fraction and gap size distribution. respectively. Although the difference between Ωee and Ωlx is only smaller than 0.1. the difference between LAIcc and LAIlx can reach up to 0.36. Path length algorithm...
This paper proposes a framework of change detection with multi-source remote sensing images through collaboration of multiple operators. Firstly, pre-processed images are distributed to different operators. Then the images are classified by the operators independently. Finally, with uploaded classification results, change detection result can be derived through evidential fusion based on PCR5 rule...
Leaf area index (LAI) is a critical parameter in many terrestrial ecosystem models. Continuous LAI measurements from global sites are an important dataset for the validation of remotely sensed LAI products. However, the spatial scale mismatch between the site measurement and the product pixel grid hinders the utilization of multi-temporal ground LAI measurements. In this study, a pragmatic method...
The study intends to explore EFL learners' Rhythm of English through a phonetic experiment over the reading-aloud task produced by the English learners from Guangxi Zhuang Autonomous Region. The tested subjects are grouped as the first-year non-major learners(NM1), the second-year non-major learners(NM2), the first-year major learners(M1) and the second-year major learners(M2). On the basis of the...
We report the fabrication and study of coreshell InGaN/GaN multiple quantum well (MQW) nanorod photovoltaic device. The nanorods were fabricated from a GaN substrate by top-down etch, followed by InGaN/GaN MQW growth. The 3D geometry allows higher Indium incorporation and extends the solar absorption spectral range as compared with a planar reference sample. The proof-of-concept coreshell nanorod...
With the advent of cloud computing, a significant number of web services are available on the Internet. Services can be combined together when user's requirements are too complex to be solved by individual services. Since there are many services, searching a solution may require much storage. We propose to apply a compact data structure to represent the web service composition graph. To the best of...
In the application of ultrasonic flowmeter, flow measurement has a low accuracy, since the length of straight pipe near the ultrasonic sensor is insufficient, especially the presence of the upstream disturbance. In this paper, in order to analyze the inherent relationship between the measurement error and the characteristics of flow field, two flow diagnostic criterions are proposed: asymmetry index...
Hetao Irrigation District, located in Bayan nur city of Inner Mongolia, is one of the largest irrigation areas in Asia. Because of little rainfall and large evaporation, lack of water resources has become one of the main factors which restrict the development of the local economy. Real-time monitoring of the actual irrigation area can contribute to efficient allocation of water and soil resources...
We report the operation of a highly sensitive, tunable and stable RF interferometer, which is based on quadrature-hybrids. The interferometer is used to characterize and analyze DNA molecules, pBluescript (SK+) and pET21a, in ∼1 nL DI water solutions. The obtained RF sensitivity at ∼10 GHz is better than ∼3×10−15 mol/mL, which is close to the previously reported highest result. DNA molecular compositions...
GPR signal is essentially a delayed, scaled and distorted version of the transmitted pulse, determined by sparse parameters such as time delays and amplitudes. The time delay indicates the detected target's depth, and the amplitude is the impedance contrast at interface or reflection coefficient. A system for sampling GPR signal at an ultra-low sampling rate based on the Finite Rate of Innovation...
For humanoid robots, there exist a class of challenging tasks, e.g. playing table tennis, which are non-repeatedly, triggered randomly by sensor events, and compelling the robots to produce reactive operations in very short time. Additionally, some key poses of the robot are partially constrained to accomplish the operations, and are usually adjusted during the operation execution. In this paper,...
The permutation conditional mutual information (PCMI) is proposed to estimate the directionality index between EEG signals. First, we demonstrate numerically that PCMI was a robust method to quantify the direction of information flow between time series from strongly and weakly coupled systems. Then, the PCMI method was applied to investigate the coupling direction between intracranial EEGs recorded...
Reliability evaluation can help designers to judge quality levels of products and improve their design. This paper evaluates reliability with considering customer satisfaction index (CSI). CSI is widely used in the field of economics to evaluate economic performance and feasibility. Using CSI and fuzzy synthetic assessment (FSA), we can get a satisfaction level about lithography machine. Five main...
Research on county public expenditure performance evaluation system, not only create conditions for more effective, results-oriented performance budgeting reform, but also provide direction of enhancing the capacity of public services for the grass-roots government. This paper attempts to construct the county public expenditure performance evaluation index system, in order to objectively evaluate...
Abstract-The factors that influence the development of agricultural products logistics enterprises are determined, and the index system is built. The Delphi technique is used to determine the relationship between the factors, and the direct-relation matrix is built. Then the effects of the factors are analyzed quantitatively by decision making trial and evaluation laboratory (DEMATEL) approach. Based...
In this paper, we construct the measurement model with the six central provinces 2000–2009 panel data, and derive the provincial effects from the technical options for the upgrading of industrial structure. The conclusion illustrates the technical options play an important role in promoting the upgrading of industrial structure and regional economic growth. We believe only by combining elements of...
