It is accepted that improving water efficiency a key task for China in achieving sustainability, as the knowledge of and its determinants can provide critical information policy formulation. To this end, paper presents parametric frontier approach to analyze performance influencing factors one step. The proposed first introduces Shephard distance function construct total-factor (TFWE) index then adopts stochastic analysis (SFA) technique compute determinants. A case study regions from 2000...

Positron emission tomography (PET) suffers from limited spatial resolution in current head and neck cancer management. We are building a dual-panel high-resolution PET system to aid the detection of tumor involvement small lymph nodes (10 mm diameter). The is based on cadmium zinc telluride (CZT) detectors with cross-strip electrode readout (1 anode pitch 5 cathode pitch). One challenge that angular coverage imaging volume leads artifacts reconstructed images, such as elongation lesions. In...

Aiming at the problems of traditional earned value method widely used currently, this article established a quality model, and built up project evaluation system, considering factor. This model can improve perfect existing Earned Value, coordinate three control objectives, quality, cost schedule, based on fuzzy membership. It comprehensively measure reflect actual situation overall progress, thus ensuring integrated management objectives schedule.

In this paper, we first used principal component analysis to extract the main financial risks affecting indicators based on spss17.0. And then construct corporate Financial Early-warning Model through use of Logistic Model. We selected a total 60 companies as our sample listed forecast Empirical model include 30 ST and non-ST comparison.

The urban resident trip-mode share rate is a significant index of transportation pattern and its development level. It one the important issues in study to forecast effectively so as determine whether present structure reasonable. This paper produces an improved Grey-Markov Chain method by combining Grey Model Markov Chain, based on this method, establishes trip- mode forecasting model exploringly. Firstly, Model, then revise prediction obtain more accurate result. takes private car Nanjing...
