Many types of robots are used in automobile industry such as spot welding robot, body painting robot, material handling robot etc [2].
Analysis of g-forces are important in a variety of scientific and engineering fields, especially planetary science, astrophysics, rocket science, and the engineering of various machines such as fighter jets, race cars, spot welding robots and large engines.
Optimization The criterion for failure of ductile material is Von-misses stress (VMS) [13, 14].

Researching in Shallow Parsing based on Function Invariance of Maximum Likelihood Estimation Shuang Zhang1,a, Shixiong Zhang1 1School of Information Science and Technology ,No.210 Mailbox, No.74 Xuefu Road, NanGang District, Harbin, Heilongjiang Province, China a15204699538@yeah.net (corresponding author) Keywords: shallow parsing, function invariance, chunks, unsupervised partial parsing (UPP), maximum likelihood estimation Abstract.
The method of instance-based learning Compares to the estimation of emission probability parameter, transition probability adopted more statistical phenomena dimensionality, as result, after using the sub-category of syntax based on the part of speech of the word, a certain extent of data sparse could be brought out in the statistic space of transition probability. [9] Due to the method was not added into the statistic of sub-category, so in the training language material, in some certain circumstance, statistic space did conclude some statistic issues of testing data.
Before the estimation of transition probability parameter, based on labeling sub-category, using the parameter estimation method of low dimensional interpolation label led the training language material.

Introduction In recent years, with the development of science and technology, small parts have a wide range of applications in various industries.
The creation of this micro milling model is based on Ko and Dornfeld’s model that used a continuous works with orthogonal cutting burr model and then do a little hypothetical [3] : (1).The model is based on the geometry process of burr formation and the nature of the workpiece materials is assumed to be constant in the whole process

The separation density indicates the specific gravity of the material in the feed that is equally divided between the clean coal and heavier product.
However, when the air flow rate exceeded certain limit, fluidized bed porosity got bigger, the randomness of material movement got larger, kinetic misplacing effects of dense medium played a leading role, back mixing of dense medium was serious, separation density was unsteady, and the separation effect was also poor.
