It is possible that the excessive dynamic responses of tunnel elements could jeopardize the safety and accuracy of installation procedures used during subsea tunnel construction.
Coincidence within the accuracy of the installation of the combustion energies and completion of the aldehyde samples obtained after recrystallization of different multiplicities (A, B, C), (Table 4) is indicating their sufficient purity for use in the calorimeter.
By using a single-view-point constraint determination method [20] and by adjusting the device, the single-view-point constraint was considered to be satisfied during camera-mirror assembly, and the installation accuracy of the mechanical structures was guaranteed.
In order to specify and design sensor systems, evaluation of "first cost" effectiveness such as qualitative items like installation time, accuracy, precision, reliability, repeatability, durability, maintenance, repair/replacement costs, compatibility, and various other factors are considered.
Recently, devices that can perform similar functions with higher accuracy and reliability, easier installation, lower maintenance and longer life span have been introduced (e.g. sensysnetworks.com).com
A method can be selected on the basis of the volume of water to be measured, the degree of accuracy desired, whether the installation is permanent or temporary and the financial investment required (Tobias et al. 2001; Parker et al. 2004).
For both types of approaches, the various implementations differ greatly in their speed, accuracy, coverage, ease of installation and use, and in the interpretation and visualization of the results.
They are useful for inspection work or for installations where accuracy is not critical, but longer levels are essential for construction work.
The accuracy, response time, reproducibility, and installation were discussed and compared.
The device has been used in some China high-speed railway sites and it has the advantages of high accuracy, low-cost and easy installation.
