Quality oriented value and performance drivers

The quality endeavors of an organization, like other enterprise activities, must be oriented towards the economic principles. This approach gives a way to many organizations to question the extent to which the quality management contributes for the overall business success and to pin point the areas where particularly a high value or performance can be created in order to attain the maximum possible economic benefits out of quality management systems. Without including the answer of this question in the decision making process, the resources can not be allocated optimally for the quality purpose. Quality management activities create variety of effects that indirectly contributes towards the economic success and thus increase the company and stakeholder value. A closer look at the quality management philosophy reveals eight major principles namely： customer focus, leadership, involvement of people, process approach, system approach to management, continual improvement, factual approach to decision making, mutually beneficial supplier relationships. These eight principles lead the efforts in the domain of quality management to project a positive impact on the company. For an understanding of response relationships, it is necessary to consider in detail the indicators along the response relationships. They provide helpful clues and give an insight into the complex mechanisms of action of the quality approaches on the path to the company＇s success. The following illustration depicts how the quality based activities generate the value to enhance the performance and a variety of indicators reflects how they indirectly add value to an organization and hence contribute to its economic success.

Main progress and prospect for China’s hydrogeological survey

This paper reviewed the main achievements of hydrogeological survey in China,summarized the significant progress of hydrogeological survey over the past decade,and forecasted the key responsibilities for hydrogeological survey in the“14th Five-year Plan”.The significant progress includes:China established the 1:50000 standard hydrogeological survey system with Chinese characteristics and produced the new generation of highquality hydrogeological maps;the national groundwater monitoring project was completed and accepted,which marks China taking the leading position in groundwater monitoring internationally;fruitful results were achieved in the national groundwater quality survey,and groundwater quality background values were basically identified and checked;hydrogeological and environmental geological survey was continuously promoted in karst areas and the ecological restoration of rocky desertification achieved remarkable results;China strengthened layer exploration techniques for groundwater,integrating the key and practical techniques of layer exploration and monitoring;the exploration of groundwater in the poverty-stricken regions and old revolutionary base areas were effectively promoted to strongly guarantee the poverty alleviation and drinking water safety;the mystery of desert groundwater was uncovered,making up for the shortage of 1:250000 hydrogeological survey in the Badain Jaran Desert;and more efforts were made to conduct survey on the water resources in the basin,and to finish the unified measurement of national-scale groundwater level.

Internet Multimedia Traffic Classification from QoS Perspective Using Semi-Supervised Dictionary Learning Models

To address the issue of finegrained classification of Internet multimedia traffic from a Quality of Service(QoS) perspective with a suitable granularity, this paper defines a new set of QoS classes and presents a modified K-Singular Value Decomposition(K-SVD) method for multimedia identification. After analyzing several instances of typical Internet multimedia traffic captured in a campus network, this paper defines a new set of QoS classes according to the difference in downstream/upstream rates and proposes a modified K-SVD method that can automatically search for underlying structural patterns in the QoS characteristic space. We define bagQoS-words as the set of specific QoS local patterns, which can be expressed by core QoS characteristics. After the dictionary is constructed with an excess quantity of bag-QoSwords, Locality Constrained Feature Coding(LCFC) features of QoS classes are extracted. By associating a set of characteristics with a percentage of error, an objective function is formulated. In accordance with the modified K-SVD, Internet multimedia traffic can be classified into a corresponding QoS class with a linear Support Vector Machines(SVM) clas-sifier. Our experimental results demonstrate the feasibility of the proposed classification method.

A NEW OBJECTIVE STEREOSCOPIC IMAGE ASSESSMENT MODEL BASED ON STEREOSCOPIC PERCEPTION

In order to establish a stereoscopic image quality assessment method which is consistent with human visual perception,we propose an objective stereoscopic image quality assessment method.It takes into account the strong correlation and high degree of structural between pixels of image.This method contains two models.One is the quality synthetic assessment of left-right view images,which is based on human visual characteristics,we use the Singular Value Decomposition(SVD)that can represent the degree of the distortion,and combine the qualities of left and right images by the characteristics of binocular superposition.The other model is stereoscopic perception quality assessment,due to strong stability of image’s singular value characteristics,we calculate the distance of the singular values and structural characteristic similarity of the absolute difference maps,and utilize the statistical value of the global error to evaluate stereoscopic perception.Finally,we combine two models to describe the stereoscopic image quality.Experimental results show that the correlation coefficients of the proposed assessment method and the human subjective perception are above 0.93,and the mean square errors are all less than 6.2,under JPEG,JP2K compression,Gaussian blurring,Gaussian white noise,H.264 coding distortion,and hybrid cross distortion.It indicates that the proposed stereoscopic objective method is consistent with human visual properties and also of availability.

Study on the Inelastic Attenuation Coefficient,Site Response and Source Parameters in the Southeast Area of Gansu Province

Using digital seismograms recorded by the Gansu digital seismic network, the inelastic attenuation coefficient is calculated based on a genetic algorithm and the method proposed by Atkinson. Then, the site response and source parameters are investigated by the Moya method. The inversion results indicate the frequency-dependent inelastic attenuation, Q value, in the southeastern Gansu is estimated as Q （f） ： 404.2f^0.264 . Except for the Tianshui station, the site responses of the other stations do not show significant amplifications, which is consistent with their basement on rocks. The stress drops of all 39 earthquakes range between 1 × 10^5 and 7 × 10^6 Pa. We also found the dependence of corner frequency on seismic moment and seismic magnitude.
