This paper studies weight adjustment in multiple attributes group decision making model. Firstly, the attribute weights respectively calculated by methods of AHP and entropy are optimized based on objective programming model. Secondly, the initial weights of decision-makers are updated by the grey correlation degree between the individual decision results and the group decision results. Furtherly, the group decision results are updated. Then the weight-adjusting is continued on the basis of the new group decision results. Based on 2-Norm Minkowski measure, the steady weights of decision-makers and final results of the group are gotten with the process of adjustment. Finally, a numerical example to evaluate wind power equipment supplier shows the feasibility and practicability of the proposed algorithm.

In modern geophysical prospecting, GPR has been more and more widely used due to its accuracy and high efficiency. However, different site conditions and a rather strict demand for equal-distance reminding actually set limits on the traditional application method of GPR. In solving this problem, a new MCU-controlled equal-distance reminding device has been designed to form a new site sampling platform. With the reduction of the difficulties in equal-distance reminding as well as technical distortions, a revised more practical MCU-assisted GPR site sampling method has formed. The practical application case proves this method more efficient. Compared to the traditional method, the new one improves the sampling accuracy, diminishes positioning inaccuracy from movement and reduces limits set by the environment. In all, this new sampling method eases the process of detecting underground karst caves and improves the accuracy.

Accurate project effort prediction is an important goal for the software engineering community. To date most work has focused upon building algorithmic models of effort, for example COCOMO. These can be calibrated to local environments. An approach to estimation effort based upon analogy researched in the paper. Collaborative Filtering has been developed in information retrieval researchers successfully which recommends items based on other user's reference in historical data set. Effort estimation based on Collaborative Filtering is researched. The similar projects set are found from historical projects set using the method for document similarity, and then effort is estimated using the weighted sum of the efforts in k-nearest neighbors. The method is applied in an experimental case to evaluate the effort estimation, and the result shows the accuracy of estimation may arrive to 90%.

In emotional physiological reaction experiments, to pinpoint the physiological signals which contain reliable emotional physiological responses is significant for subsequent emotion analysis and recognition. Combined with the continuous emotional rating method, this article uses random matrix theory to analyze the cross-correlation of some pulse physiological signals which are collected from more than 100 ordinary university students about happy, anger, fear and sadness four kinds of emotions. By this method, we attain the precise location of these physiological signal segments with reliable emotional responses in complete physiological signals, to ensure the data validity of subsequent affective computing.

The sentiment information implied in the content of Social Networking Services (SNS) is of great technical and social significance, which has attracted a lot of researchers in different fields. Chinese text sentiment analysis is still in its starting stage, and most of the previous sentiment analysis algorithms are either inaccurate or inefficient. The purpose of this paper is to propose an algorithm performing well in both accuracy and efficiency, and apply it into a real time platform. A sentiment analysis algorithm on Chinese micro-blog content is introduced firstly, which achieves an outstanding accuracy but performs badly in efficiency. Then we optimize it with three strategies: data structure optimization, query strategy optimization, and parallel optimization. The experiment shows these strategies are very effective and the optimized algorithm is over 100 times more efficient than the basic algorithm. Based on the optimized algorithm, a text sentiment analysis platform is developed for real time sentiment. The platform offers two main functions including text sentiment analysis and user sentiment timeline. The results are outputted through a group of open APIs, which can be revoked by other developers and reduces their development costs. As a whole, the platform performs well on responding rate, capacity of concurrent users, stability and expandability.

Electromagnetic environment is becoming more and more complex in modern battlefield. Using direct volume rendering to describe it is helpful for the commanders to understand the electromagnetic situation. To realize the volume rendering of electromagnetic environment data, the work in this paper uses ray casting algorithm rendering the electromagnetic environment sample data, with the analyzing and solving of the ray correction problem when the sample data are transformed between different coordinate systems. To improve the rendering efficiency, the CUDA is used to speed up the data updating and rendering. The experiment results show that the complex electromagnetic environment can be rendered in real time with the using of CUDA, and the electromagnetic situation information can be clearly displayed with real-time interaction.
