In 2010 HP® introduced three new server blades and an update to OpenVMS® that will extend the life of the OpenVMS environment for many years. The BL8x0c i2 server blades use quad-core Intel® Itanium® 9300 processors. OpenVMS V8.4 offers improved performance designed for these new BL8x0c i2 server blades. This paper provides detailed analyses of the performance advantages of OpenVMS V8.4 running...

The paper proposes a methodology for reliable design and maintenance of wind turbine rotor blades using a condition monitoring approach and a damage tolerance index coupling the material and structure. By improving the understanding of material properties that control damage propagation it will be possible to combine damage tolerant structural design, monitoring systems, inspection techniques a...

The problem of searching for the best arrangement of mistuned blades on a bladed disc is formulated and solved as a combinatorial optimization problem. The maximum response level is chosen as the objective function and the individual blade mistunings are the design variables. Gradient-based response surface approximations are built for the objective function benefiting from a inexpensive calcul...

Our research consists of the experimental study vertical wind turbine form H. The represents effect number blades in variation rotations turbine, speed ratio, torque, power and torque force. Hshaped axis was carried out hall University Biskra, where manifested dimensions imposed experiment from length propeller extent its curvature width propeller; we also recorded each numbers turbines. Eviden...

In this paper, effect of geometric parameters of a centrifugal fan with backwardand forward-curved blades has been investigated. Centrifugal fans are used for enhancing the heat dissipation from the IC engine surfaces. In the process, the fan consumes power generated from the engine. As a first step, an experimental setup was developed and prototypes of fans were made to carry out measurements ...

Due to the diminishing reserves of fossil fuels and increased pollution from exploitation of these fuels, the world is focusing on the renewable energy sources. Energy from tidal waves is one of the most exciting forms of renewable energy because of its consistent nature. Hence, the predictable, consistent and reliable nature of marine currents has enthused the researchers to emphasize on harne...

Turbine balancing is an important and regular maintenance operation at airline companies. Because of manufacturing inaccuracies, variations occur in the weights of the blades that can, in turn, lead to significant out-of-balance forces on the engine. The overall time required for balancing can be significantly decreased if the best placement of turbine blades is first determined mathematically....

Silver Queen mint in central British Columbia, is located approximately 35 kilometres south of Houston and 3 kilometres east of 0wt.n Lake (Figure 2-7-1). Although currently inactive, it was worked briefly in the early 1970s for gold. silver, copper, zinc, lead and cadmium. The deposit is hosted by Cretaceous rocks of the informal Tip Top Hill group (78.322.67 Ma, K-Ar whole rock), with the age...
