Self-occlusion is a challenging problem existing in human pose estimation. In this paper we exploit a new cue to solve this problem: the torso orientation. We describe a technique to automatically detect self-occlusion in training set without visibility label. Given this prior information, we are able to jointly learn an occlusion-aware model to capture the pattern of self-occluded body parts. We...
The global ocean net primary production (NPP) was estimated from satellite-derived information using a phytoplankton pigment absorption ( )-based model. Satellite-derived spectral-averaged was used as the key predictor of phytoplankton photosynthetic efficiency in the model. The -based model yields an annual integrated NPP of approximately ...
This study aims to look beyond the quantitative summary to provide a more comprehensive view of online user-generated content. We obtain a unique and extensive dataset of online user reviews for hotels across various review sites and over a long time periods. We use the sentiment analysis technique to decompose user reviews into five dimensions to measure hotel service quality. Those dimensions are...
Closed-loop supply chain network with several kinds of operation links involves the manufactured and remanufactured heterogeneous products. The closed-loop supply chain network models prior to and post their horizontal integration are developed. The variational inequality formulations of the models are given. Finally, numerical examples are solved by using the proposed models.
P2P e-commerce systems are commonly perceived as an environment offering both opportunities and threats. The existence of malicious peers could damage the correctness and availability of them. One way to minimize such threats is to use trust model to evaluate the trustworthiness of peers. This paper presents a dynamic self-adaptive trust model for p2p e-commerce system - AdaptTrust model, which involves...
The aim of this study is to examine the factor structure of the scale of Job Satisfaction Survey (JSS), and its divergent and convergent validity in Chinese population. Data were collected with JSS from 1073 urban employees in Liaoning. Four alternative models were tested with confirmatory factor analysis. The first two models are models validated in the US, while the third and fourth models are composed...
This paper studies the use of static synchronous compensator (STATCOM) for wind farms integration based on DFIG, and proposes a reactive power cooperative control strategy for the wind farm combined with STATCOM. A whole dynamic model for variable-speed constant-frequency wind energy system and the STATCOM are established in the PSCAD/EMTDC environment. On the basis of this model, the reactive power...
This text has set up a comprehensive appraisal model and method for Green Product, which is utilized with coordinated analytical method. In practice, every thing has advantages and disadvantages in themselves at the same time. The model can balance the both sides of it, and provides an optimal answer for the sequence of the projects. Meanwhile, it provides green products comprehensive index system...
The study investigates the relationship between environmental satisfaction and personal well-being with a sample of 336 urban residences from 4 Chinese cities: Changchun, Dalian, Harbin and Shenyang. In contrast to previous studies, this study controlled job satisfaction and Big Five personality traits. In addition, the research variables of PWI, job satisfaction, Big Five, and environmental satisfaction...
A closed-loop supply chain network includes two firms, who are involved in the manufacture and remanufacturing heterogeneous products. The network comprises operation links to represent business activities. We present the models prior to horizontal merger and post two firms merged. The variational inequality formulations of the models are given. We illustrate the proposed models with numerical example.
A large-scale enterprise is planning to select right locations to open a number of firms and enter an existed industry. The entering enterprise has to compete with the existed enterprises. Furthermore, original network economic equilibrium must be break and the network will attain new equilibrium state. Hence, one-leader-multiple-followers Stackelberg strategies problem is discussed that the entering...
A bi-level programming model is proposed by using the methods of equilibrium theory and variational inequality. The upper level model accounts for that the environmental protection agency can promote environmental benefit at possibly lower incentive and supervision costs. The lower level model describes the competitive behavior of the decision-makers under different incentive and supervision strategies,...
Horse traversing problem was a hard problem to solve with traditional computer; and there were no efficient algorithms to solve this problem with traditional computer when the measurement of problem was very great. In order solve this problem, the extended horse traversing problem was transformed into directed Hamilton path problem, and was solved by using Adleman DNA computing model. A DNA algorithm...
Choosing a cotton variety involves making comparisons over many trials and across an increasingly large number of available varieties. To aid in this process, a computerized tool has been developed at the Texas Tech University. This tool, called COTWIZ, based on the cotton variety selection model, allows multiple comparisons of varieties across a number of trial locations. COTWIZ based on the cotton...
A new quantified model of evaluating the economic risk of technology innovation project which based on Monte Carlo simulation technology has been proposed in this paper. That is use three point which are maximum possible value, minimum possible value and the most possible value to estimate the risk variable. Using AHP method, variable weight of delivered and extended risk to determine the weight of...
The paper improved the evaluation model of real estate project risk which based on Monte Carlo simulation technology. That is use three point which are maximum possible value, minimum possible value and the most possible value to estimate the risk variable. Using AHP method, variable weight of delivered and extended risk to determine the weight of each risk factor in the model objectively, and verifying...
