The energy efficiency level of wind turbines reflected its operation efficiency and provides evidence for the diagnosis. Currently, the evaluation study is concerned essentially with a part of Wind Turbine, but that has limitations. This paper establishes a synthetic evaluation index system of the energy efficiency evaluation of Wind Turbine from five respects, which include Comprehensive, profitability,...
In order to evaluate the efficiency of system communication network in energy internet, the evaluation index system should be established firstly. There is no unified standard for the efficiency evaluation index system of complex power electronics system based on Software Defined Network (SDN) now. The function of SDN in complex power electronics system is introduced in this paper and the characteristics...
The $(n,k)$ combination property (CP) is defined as follows: $k$ source packets are mapped into $n \geq k$ packets and any $k$ out of these $n$ packets are able to recover the information of the original $k$ packets. This $(n,k)$ CP is extensively needed by cloud storage service providers. Reed-Solomon (RS) codes possess CP at the cost of high encoding and decoding complexity for two...
Life detection using Ultra wideband (UWB) radar has become more and more important in civilian and military areas. Life detection is a technology of potential use, which can be widely used for post-disaster rescue, patient monitoring, wireless body networks and so on. In this paper, we propose an improved cell averaging constant false alarm (CA-CFAR) detector for life detection using UWB radar. The...
At present, electric power industry is in a period of rapid development and the assessment of regional power development captures growing attention. Through the evaluation process, we can deepen the understandings of regional development ability and puts forward suggestions for the further development. However, the understanding of regional power development is still at the perceptual level now and...
Human body can obtain proprioception through the tactile sense. When part of the body is stimulated by tactile vibration at a particular frequency, a periodic electrophysiological brain response is elicited in the EEG activity. This response, called the steady-state somatosensory evoked potentials (SSSEPs), has the same frequency components as the driving tactile stimulus and sometimes also higher...
Patent quality evaluation and applications are important issues for new products generation. In recent years, Taiwan government also actively pushes the patent-related laws and rules to strengthen the development of national patent technologies and their protection utility. In order to deal with large amounts of patent information to enhance the patent expansibility and technology transfer possibility,...
This paper proposes a framework based on harmonic mean normalized Laplace-Beltrami spectral descriptor for non-rigid 3D shape retrieval. A series of experiments show harmonic mean normalization is suited to classification of stretched shapes, and is robust to isometric transformation, holes, local scaling, noise, shot noise and sampling. To better distinguish among shapes with fine or rough details,...
In this paper, the inherent mechanism of benefits associated with smart grid development is examined based on the Pressure-State-Response (PSR) model from resource economics. The emerging types of technology brought up by smart grid development are taken as pressures. The improvements of the performance and efficiency of power system operation are taken as states. The effects of smart grid development...
A quality metric called sparse feature fidelity (SFF) is proposed for full-reference image quality assessment (IQA). It is inspired by the fact that images are transformed into sparse representations by the primary visual cortex which is the most important part of the human visual system (HVS). The proposed method is based on sparse features that are acquired from a set of feature detectors called...
In recent years, there is an increasing interest in the research community in finding community structure in complex networks. The networks are usually represented as graphs, and the task is usually cast as a graph clustering problem. Traditional clustering algorithms and graph partitioning algorithms have been applied to this problem. New graph clustering algorithms have also been proposed. Random...
Greenway network of the Pearl River Delta provides public with green open spaces for the low-carbon travel and outdoor leisure activities of people. The idea "green, ecological, livable, well-being" of urban greenway changes the citizen's trip mode and consumption concept. Greenway construction and utilization are still in the exploratory period in China, it is essential to research user's...
Through comparative analysis of the international different measurement methods of information levels, the paper established the evaluation index system for China's information level, by using factor analysis methods, and the comprehensive evaluation for the six provinces on central China's information level, It aims at developing information resources, training information technology professionals...
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...
Focusing on the problems of fragile ecological environment and increasing soil erosion in the water resource area of Beijing and Tianjin, land suitability evaluation is badly needed, which is also can be the guide for land development uses and modern agriculture construction. Taking the Dongbeigou small watershed in Pingquan county of Hebei province as the study area, matter element analysis method...
17 tomato cultivars inoculated with larva nematodes were used in this paper to investigate their resistance to root knot nenatodes. The results showed that gall index of LA1312, 3601, HA4402, LA1007 were higher than other tomato cultivars. Compared with control ‘Caihong101’, root activity of LA0655 was higher, and the lowest root activity was observed in 3601, whose gall index was the highest among...
Wireless Body Area Networks (WBANs) are mainly characterized by deployment of biomedical sensors around human body which transmit vital signs measurements about healthy status to the coordinator. Depending on the relevance between symptoms and diseases, it may not be necessary for every sensor to transmit its measurements for diagnoses. This paper shows how the relevance can be exploited on the Medium...
This article constructed various indices to reflect the economical development of China. The indices were based on the direct investment Panel Data of major capital export countries from 1991 to 2009. A panel data model was employed to study empirically factors influencing the influx of foreign direct investment during the reforming and opening-up period of China. The comparative advantage, traits...
The extension method based on entropy weight is a new safety evaluation method. Entropy weight, which is an objective weight, was ascertained by entropy theory. As a result, the subjectivity in ascertaining the weights of more factors in lower hierarchy was avoided. The comprehensive correlative degree was taken as the evaluation criteria in this method. Therefore the subjectivity of evaluation model...
