Methods for Industrial Measurement and Basic Principles of Their Choices

In this paper,a variety of industrial objects are systematically analyzed.Ten methods for industrial measurement are summarized.For each method,its nature,advantages,disadvantages and adaptability are briefly given.The basic principles to choose the right industrial method are indicated.

A New Method for Measuring the Stitch Length of Weft Knitted Fabric in a Static Environment

It is essential to measure the stitch length of weft knitted fabric in a static environment for economy and improving productivity. The image inputted was dealt with the digital image processing techniques： the paper carried out the transformation of grey scale; then removed impurities with filtering; the characteristic of the stitch structure was abstracted by using the Fourier transform technique. To obtain the stitch length more accurately, we should establish ageometric medal of the stitch lined on the digital image processing, which provides a way to transform the stitch length in the two-dimenslon space into a three-dimension space. This study provides a new methed for measuring the stitch length without damaging the fabric.

A Modified Outlier Detection Method in Dynamic Data Reconciliation

Data reconciliation technology can decrease the level of corruption of process data due to measurement noise, but the presence of outliers caused by process peaks or unmeasured disturbances will smear the reconciled results. Based on the analysis of limitation of conventional outlier detection algorithms, a modified outlier detection method in dynamic data reconciliation (DDR) is proposed in this paper. In the modified method, the outliers of each variable are distinguished individually and the weight is modified accordingly. Therefore, the modified method can use more information of normal data, and can efficiently decrease the effect of outliers. Simulation of a continuous stirred tank reactor (CSTR) process verifies the effectiveness of the proposed algorithm.

Measurement of Surplus Labor in Viet Nam Agriculture

The large shift of surplus labor from agriculture to industry and services is seen in many countries around the world as well as in Vietnam in the process of industrialization and modernization of the country that has set questions about the sustainability of rural surplus labor： is there still a source of surplus labor in rural areas？ If so, how large is the source of surplus labor and how long it can be lasting？ These questions were hotly debated in the literature abroad. But in Vietnam there is very little or hardly exchanged opinions about the concepts and methods of measurement of surplus labor in general and surplus labor in agriculture in particular. This article refers to the measurement approach of surplus labor in agriculture in Vietnam.

Re-measuring Productivity, Energy and Environmental Factors of China＇s New Industrialization

This paper identifies low-carbon, energy-efficient, and green economic growth as the primary goals of China＇s new industrialization and defines productivity under new industrialization which; unlike conventional productivity, simultaneously satisfies these goals. In contrast to conventional methods for measuring productivity, this paper employs a non-radial, non-angular SBM directional distance function to estimate new industrialization productivity of industrial sectors across 30 Chinese provinces, municipalities and autonomous regions between 1998 and 2008. Our research shows that conventional measurements of productivity overestimate industrial growth in China＇s central and western regions. On the whole, prospects for growth performance of China＇s industrial sectors are not optimistic. The degree of new industrialization is higher in eastern region than in central and western regions, where balancing industrial growth with resources and the environment is a daunting task. This paper＇s conclusions support ＂environmental Kuznets curve＂ and ＂Porter hypothesis＂ but reject ＂pollution asylum hypothesis ＂.
