In structural simulation and design, an accurate computational model directly determines the effectiveness of performance evaluation. To establish a high-fidelity dynamic complex assembled structure, Hierarchical Model Updating Strategy (HMUS) is developed for Finite Element (FE) updating with regard to uncorrelated modes. The principle HMUS first elaborated by integrating hierarchical modeling...

One of the favorite dishes among meat products is sausage. Any store offers a wide range sausage and there are many varieties sausages that meet requirements for quality price. Sausage packaging plays an important role in this. To date, our market developed such way domestic manufacturers have all opportunities to compete with foreign manufacturers. Special attention should be paid natural shel...

Geotechnical survey is an important prerequisite to the construction of offshore wind farms. However, impact underwater noises has not yet been studied in details. In this paper, we transmission from exploratory drilling (OED) at Xiamen port. The were categorized into three types: hammering (hammering down casings, which 180-mm diameter steel pipes), vibrating (vibration casings that had hammer...

Oil-reservoir management using measurements and control techniques have been in use by oil and gas industries to improve the production and maintenance of the existing oil reservoirs. In the course of this project the applications of UWB radar systems and techniques to acquire near real-time information about the oil reservoir conditions are studied. Various oil reservoir structures such as oil...
