With rapid development of digital content industry, the industry has been considered as an important part in the global economic system. This paper provides a model for the digital content industry value chain and a research on all segments of chains as well as on the correlations of all segments through analysis on the digital content industry chain. The value activities raising the digital content...
From the perspective of human resources management, this survey discusses the correlations between job burnout in college teachers and school environment by means of Maslach Burnout Inventory-General Survey (MBI-GS) and School Environmental Scale, in which 416 college teachers are involved. The findings indicate the status of job burnout in college teachers is not severe according to theoretical value,...
In order to obtain some basic data for eco-toxicological tests, acute lethal toxicities of o-nitrochlorobenzene, m-nitrochlorobenzene and 2,4-dinitrotoluene in aquatic environment to Brocarded Carp were investigated. Brocarded Carp was employed and introduced into different test solutions contained three compounds. LC50 defined within 96 h was calculated by the mortality of fish using the Karbers...
An approach was proposed, which was applied Monte Carlo Simulation and risk analysis tool to assess cost risk in bidding phase, called CRA-MC. Last it was illustrated by simple camp-site construction example to show the benefits of this approach.
This paper expounds the basic content of Interrelated Tree Method, and builds the Interrelated Tree model of EPC project risk management; On this basis, the paper makes a risk list with the combining methods of qualitative and quantitative analysis and through the prediction and identification of the risk in the EPC project's whole process, and sets up risk assessment index system of all stages of...
In this paper, ridge regression (RR) method is adopted for predicting the formation of microporous aluminophosphate AlPO4-5 based on a database of AlPO synthesis, which aims to provide a useful guidance to the rational synthesis of microporous materials as well as other inorganic crystalline materials. To solve the problem of class imbalance, four guided resampling methods proposed in our previous...
The selection of a machine tool among the alternatives is a multi-criteria decision-making (MCDM) problem including both qualitative and quantitative criteria. The conventional approaches to machine tool selection problem tend to be less effective in dealing with the impreciseness or vagueness nature of the linguistic assessment. Under many situations, the performance values of the alternatives with...
Most of the Estonian coastal sea in the western part of the Gulf of Finland is characterized by numerous small bays. Some of them are open to the waves and water exchange with the open sea area, while others are exposed to waves from only one direction and have therefore limited water exchange. The coastal sea in the northeastern Baltic Proper is more open to wave and current activity. The bottom...
This study aims to quantify the relationship between field Black soil hyperspectral reflectance and soil moisture at different depth. The stepwise regression predicting model of soil moisture at different depths was built with the spectral derivatives as independent variable, and the models were evaluated with root mean square error (RMSE) and determining coefficient. The results are as follows: (1)...
Illumination and view dependent texture provide ample information on the appearance of real materials at the cost of enormous data storage requirements. Hence, past research focused mainly on compression and modelling of these data, however, few papers have explicitly addressed the way in which humans perceive these compressed data. We analyzed human gaze information to determine appropriate texture...
The internet-based educational technology has been widely used in the medical schools all over the world. It gives a way for teachers to create online self-evaluation tests and for students to take tests without having to turn in a grade to the teachers. To test the hypothesis that internet-based online tests participation/performance is positively correlated with the final score of physiology course,...
The purpose of this study was to investigate the effectiveness of Project Oriented and Problem Based Learning (POPBL) on improving engineering student's problem solving and creative thinking competence. Thirty junior students were selected as sample objects to do experimental research of robotic design. They were divided into ten groups to conduct all procedure of POPBL and test learning achievement...
Steel industry requires high quality controls to ensure certain requirements of the final products. In on-line inspection applications for long steel products, a camera is usually placed in the top, in order to view a portion of the product while it passes under the sensor in a roll table. The high relation between the length of the steel product and the necessary resolution to carry out these quality...
A computational aesthetics model developed for the game of international chess showed a good and positive correlation with human player aesthetic assessment. The unique approach taken here suggests that, in addition to things like personal taste and environmental factors, humans also likely assess beauty based on `universal metrics' within the domain itself. From the standpoint of artificial intelligence...
The purpose of this study was to investigate whether objective models can be equally accurate for expert and non-expert viewers. We measured in both expert and non-expert viewers the subjective video quality of several high definition video sequences, which had been processed at several bit-rates using MPEG-2 and H.264 codecs. The results showed only a small but statistically significant difference,...
The influence of Cadmium(Cd) on exudation of low molecular weight organic acids (LMWOAs) were investigated based on the hydroponic culture experiment. Tartaric, citric, malic, and acetic acids were chosen as representatives of LMWOAs commonly present in roots exudation. We investigated the Cadmium accumulation in Zea Mays L.. In particular, the relationship of exudation of LMWOAs by roots with Cd...
Absolute deviation covariance can be computed faster than the classical mathematical relation, and the values obtained using it are slightly different from those calculated with the classic relation. Numerical results obtained with the new absolute deviation correlation coefficient are practically identical to those computed with the Pearson's correlation coefficient. These new algorithms are less...
According to the application of secondary water-supply system has been used more and more, the problem of water pollution in secondary water-supply system turns serious. Research was made on distributing rules of bacteria in secondary water-supply system; the variety and correlativity of water quality index were analyzed. Index that reflecting total bacteria number in water-supply system was indicated;...
The adsorption of diesel oil in seawater on biodegradable adsorbing material and the influencing factors such as salinity, pH and temperature were studied. Results showed the adsorption of diesel fitted the second-order reaction model, and the saturated adsorption capability was 6.69g/g which can be reached in 10-20min. The diesel oil removal efficiency increased with the increment of salinity and...
Based on the orthogonal test method, optimizing test on softwood cutting propagation technique of Symplocos tetragona has been carried out. The results indicated that cutting type, growth regulator type, growth regulator concentration, and treatment time had significant effect on rooting quality of Symplocos tetragona, and the best level for factors were the upper part of cuttings with terminal buds...
