Choose the strength reduction finite element method to simulate the process of canal slope excavation and analyze the influence of stage excavation on canal slope stability.
Adopt the limit equilibrium method and finite element strength reduction method, the impact of large board concrete liner on canal slope stability is analyzed, and the following conclusion is drawn
In reference to the design data of the 61 slope of canal section in main canal of east route of South-to-North Water Diversion Project and according to Design specification for slope of hydropower and water conservancy project (SL386-2007), the anti-slide stability safety coefficient affluence in the different conditions is collected in Table 1.

The reduction speed of corrosion rate of 2# RE weathering steel is the most rapid, indicating generating speed of its protective rust layer is the most rapid.
The reduction speed of corrosion rate of 3# weathering steel with 0.016% rare earth is the lowest, and its corrosion rate reaches maximum value among three RE weathering steels after corroded 240h.
From the impedance datum of the tested steels, it is found that concentration polarization impedance is caused by two different diffusion processes.
The fitting results are shown in Fig. 7, indicating the simulations are in good agreement with the experimental datum of the steels in the frequency range of 5×105~0.01Hz.

Due to the establishment of branch campus by many noted universities overseas in Taiwan after Taiwan becomes part of the WTO members, as well as the offshore migration of industry activities to other countries or to Mainland will also caused a strong challenge to the universities in Taiwan, where a recent reduction in birth rate of Taiwan in particular, has led to a reduction in annual number of school enrollment from year to year.
First, to begin with thinking, this kind of people tends to think and process message in a rational and logical way, they will review and check information as much as possible to confirm the logic and consistency of data before they make decisions.

Comparatively speaking, although the reduction based reasoning[1] can be used to decide the concept satisfiability, its advantage lies in query answering over large ABoxes, while as for the structural subsumption, it has even no practicality since it just applies to much simple DLs such as FL0.
While each ∃ transitive role literal Y has a data structure E E E E to keep its original restricting concept, denoted as EEEE(Y).

COBIT has important business value, including increased compliance, corporate risk reduction, good accountability, and proves to be a useful tool to establish a baseline for process maturity  Weaknesses of COBIT Although IT governance is considered to be an enabler for business/IT alignment, COBIT lacks in the establishment of responsibilities and a methodological alignment with the business strategy - especially when COBIT processes are used for enabling information security strategy management. 4.
Sustaining current performance while continuously reducing costs, decreasing exposure to risk and carving out resources to safely improve performance from a budget constantly targeted for cost reduction is the IT challenge.

Figure3 Friability Figure4 Pit slots 2 The moisture damage’s test analysis The parameters survey of core samples By means of the coring on the site in the different sections, compared with each other and analyzed the variability of data, the uniformity of the asphalt pavement can be obtained.After analyzed the relation about the causes for the moisture damage and construction quality, the results are shown in table 1.
Table 6 The asphalt-aggregate ratio of cores statistics under different types of damage(%) Position The frost boiling The subsidence and pit slots The crack The disease-free Top-surface 5.65 5.30 5.25 5.05 Mid-surface 4.65 4.83 4.69 4.76 Low-surface 4.49 4.52 4.62 4.63 3 Causal analysis Through a lot of field investigation and laboratory analysis, it is considered that the factors which influence the moisture damage in Hunan province are design, material, environment, construction and so on[6]. 1.Design factors:(a)Because of the existence of shrinkage cracks in semi-rigid asphalt pavement, moisture can permeate through cracks, it causes the change of the interface between subgrade and surface , the increase of the moisture content of subgrade and the quick reduction of pavement bearing Capacity which produces dynamic water pressure by load, then it appears frost boiling and pit slots through the cracks[7].
According the characteristic of rainfall of Hunan province is concentrated,this paper proposes using OGFC (open the gradation asphalt abrasion layer) to prevent the moisture damage,OGFC is a type of open-graded bituminous mixture,with excellent characteristics in good drainage, skid-proof and noise reduction, the air void of this mixture was less than 15%, the content of asphalt is relatively rare.

The experimental data show the distribution function reaches balance after 60min, and the majority of organic matter in waste water reached balance after 60min.
With the reduction of the particle size, the specific surface area of ​​organobentonite increases, the effective adsorption sites on the surface of organobentonite increases, and the removal effect of organic pollutants becomes better.
However, when the particle size of organobentonite becomes smaller, the removal effect of organic pollutants becomes worse due to the specific surface reduction caused by the fact that the small bentonite particles in water are inclined to hydrate into microgel particles.

Table 1 shows few material parameters used in this modeling, which were chosen based on experimental data, literature values, and theoretical study.
Hence, it is a clear sign of further reduction of CdTe absorber layer thickness from 1 μm to 0.6 μm with BSF is possible as proved in this analysis.
This TC indicates better stability of the cells at higher operating temperature, which are in good agreement with related works [11] Fig. 1: (a) Effect of CdTe thickness variation on the output parameters of ZnxCd1-xS/CdTe cell with BSF and without BSF (b) on the SR (c) Effect of BSR velocity on proposed cell Fig. 2: (a) Effect of BSF on the J-V (b) Effect of operating temperature on cell stability Conclusion The main objective of this analysis was to determine the effects of CdTe thickness reduction and application of ZnxCd1-xS as window layer in CdTe solar cells.

Further investigations confirmed that nature of the surface scale varies with respect to the changes of rolling temperature, reduction and cooling conditions.
On the other hand, earing control of the 3104 alloy was strongly influenced by finish rolling temperature and reduction.
Figure 10 shows that stresses predicted by the compound formula fitted well with the measured data.
