Integration of the surface pressures leads to the time series data of base moment coefficient, of which the amplitude and frequency-domain characteristics were studied and compared with those of the single-tower.
Wind tunnel test and model summary The wind tunnel test with simultaneous surface pressure measurement was carried out in TJ-2 atmospheric boundary layer wind tunnel in the state key laboratory for disaster reduction in civil engineering in Tongji University.

Therefore, reduction of the network delay and jitter has always been the improved direction which the network equipment suppliers care for.
The MPLS network is in the middle of data link layer and network layer, belonging to the 2.5 layer protocol.[1] In an MPLS network the label switched path (LSP) is established for the message through the pre-assigned label.
It can provide nanosecond-level synchronization precision in a geographically dispersed network, therefore it is available to transmit all kinds of real-time services and data services for the network.[2,3] Fig. 1 Forwarding process of MPLS The IEEE 1588 standard defines 4 kinds of synchronous messages, including Sync, Follow_up, Delay_Req, and Delay_Resp.

Some methods have been investigated including reduction the particle size to nano scale and making porous nano TiO2.
Powder surface area was determined from N2 gas-adsorption data using Brunauer–Emmett–Teller technique (BET) with Belsorb II.
The average crystallite size of the synthesized samples was calculated from the XRD data according to the Scherrer's equation [11]: [1] where d is the crystallite size, k is a constant (0.9), λ is the wave-length of X-ray (CuKα), β is the half-peak width in radians and θ is the Bragg's diffraction angle in degree.

According to statistic data, the rate of wedging or hitting bridge about large trucks stays at a high level [2].
The optical signal modulation circuit is shown in Fig.2. 1.2 Design of the Optical Signal Demodulation Circuit For receiving circuits, the SCM of receiving signal is used to process the received data.
Judging the rising-edge and falling-edge can enable and turn off the timer, next calculates the pulse width, and then comparing it with the reduction of the pulse width (preset value) can calculate the number of sensors being obscured, according to the number, the height of the vehicle can be calculated precisely .The algorithm is only suitable for measuring objects without hollow.

The average reduction of UPV was ranged 5.80 to 13.65% at 14 days, 3.25 to 11.52% at 28days and 2.65 to 10.69% at 56 days, respectively.
The obtained equations are plotted in Fig.5 with experimental data.
However, the proposed equations in this investigation are given only as a function of their compressive strength using a relatively small number of experimental data.

The initial data include facing of ceramic-granite 600х1200х12mm slabs, of 12 kg/m2 weight.
When considering the idealized scheme, where all the elements work together, we observe the resulting static force calculation and design the facade system in accordance with these data.
If we assume that some elements fail as a result of the above factors, then the reduction of the bearing capacity of the frame elements will lead to an increase in stresses in other elements, which was not originally provided.

The substitution of Portland cement with DE at 30% resulted lower global warming potential and energy use as well as appreciably reduction air pollutant emissions [10].
From the data in the table, it can be judged that the optimum water-cement ratio was 0.65.
Fig 10 shows the compressive strength data sheets of cement mortar at a water-cement ratio of 0.65.

The morphological and hydrographic map of Chirchik and Akhangaran river basins
According to the scheme of "Scheme of complex use and protection of water resources of the Syrdarya River Basin" (Syrdarya river basin Complex use and water recourses protection), as well as the data of the Kazakh branch of Intergovernmental hydroeconomic coordination committee’s Scientific research centre average annual water resources (Chirchik-Akhangaran-Keles irrigation district or CHAKID) are estimated at 9.32 km3, of which 8.67 km3 (93%) – surface water flow.
Topography of Chirchik-Akhangaran basin (DEM by GIS) The analysis of the collected data concerning gauging Chinaz in the estuary.
-development of measures to improve the management of waste waters Chirchik-Akhangaran irrigation district, including monitoring of volumes and the quality of these waters and carrying out calculations of water-salt balance in the large irrigation areas with a purpose of their sustainable use and reduction the load on the existing ecosystems and their disposal on the track of tailrace channels and others.
