Reference [5] is about the reduction of non-state estimators for descriptor systems, it does not cite specific examples to verify the validity derived.
Description of the Problem After the launch of satellites, in order to study the deviation in the orbit, we need to re-estimate the satellite orbits accurately by observation data.

Introduction Reduction in wood harvesting from Iran natural forest has caused serious impact on wood industry[3].
Data was analyzed using SPSS software.

By analyzing the test data, the appearing and developing of cracks could be observed from the elastic state to the plastic state.
And the semi-active control system only achieves a negligibly small reduction in the column strains.

Dry hobbing is a cost reduction and environmentally friendly technology, but it deteriorates the cutting condition.
The points are calculated by each ∆θ1 as substep, and the data is memorized.

If the timing belt transmission is used in SMT placement machine system to drive X shaft module along the Y direction, a significant advantage can be obtained in the smooth transmission and reduce the cost reduction.
Timing belt model (1- Timing Belt Pulley 2 2-shaft 3-motor shaft 4- Timing Belt Pulley 1 5-middle shaft 6- Timing Belt Pulley 4 7- Timing Belt Pulley 3 8- synchronous shaft l) Virtual prototype model of synchronous belt module Model simplification In the modeling process, the structure is simplified reasonably, and it can reduce the computation data of the model, and improve the simulation efficiency.

The following conventions are used for data reduction.

Key features of DDCBEM include double reduction of dimension.
Other advantages are allowance of advanced analysis in vital areas, simple data processing, effective computational schemes and computer-oriented algorithms.

Because the reasonable pile diameter, the selection of pile quantity, the data analysis results are shown that the maximum displacement, the whole maximum stress of the pile and the maximum stress of the pile are all less than the previous three layouts.
The comparison diagram of maximum stress of soil and whole soil maximum settlement, can be seen from the table.2, when pile diameter D is located in 400 mm to 800 mm, the maximal displacement and the maximum stress of soil are reduced while the pile diameter is increased, but when the pile diameter D more than 800 mm, the reduction of maximum deformation is no longer apparent, but the maximum stress of soil have increase tendency, therefore excessive increase the pile diameter is not necessary. .

Since little published data are available in the literature concering devices that use Al doped ZnO on p-Si heterojunctions fabricated by sol-gel dip coating technique, the present work was aimed to investigate capacitance-voltage (C-V) properties of Al doped ZnO on p-Si heterojunctions fabricated by sol-gel dip coating technique.
Interaction between photons and the atoms that constitute the matter result in a reduction in the intensity of a collimated beam of monoenergetic photons.

This paper proposed reusable processing tool scheduling strategy based the information management library of the tool, the integrated tool management and control scheduling, and the simulation system scheduling program is developed, and the effectiveness of this strategy is confirmed by running data in real time.
Average tool utilization rate (2) Where,-Using the total number of i-tool in this task With the reduction in the number of the tool, the total processing time is extended, but the utilization of the tool to be raised significantly by comparing the machining time and tool utilization in table 1.The higher tool utilization will make corresponding increase in tool wear rate.
