The aim of this research is to improve the reliability of the dynamic formula. This research program will concentrate on the proposal of a correction factor to adjust for this dynamic component similar to the damping parameter used in the Wave Equation Analysis and validate its reliability experimentally and theoretically. Similarly, the issue of the variation in the hammer energy delivered to pile needs to be improved by the adoption of new technology and validate experimentally.

In this research the effect of ground proximity on the lift, drag and moment coefficients of inverted, two-dimensional aerofoils was investigated. The purpose of the study was to examine the effect ground proximity on aerofoils post stall, in an effort to evaluate the use of active aerodynamics to increase the performance of a race car. The aerofoils were tested at angles of attack ranging from 0° – 135°. The tests were performed at a Reynolds number of 2.16 x 105 based on chord length. Forces were calculated via the use of pressure taps along the centreline of the aerofoils.

This article suggests a simple parameterization for the gas bubble rising velocity as a function of the volume-equivalent bubble diameter; this parameterization does not require prior knowledge of bubble shape. This is more convenient than previously suggested parameterizations because it is given as a single explicit formula.

“A ‘formula’ is something that once applied to what it is suppose to, works in any region, country or place. It’s like the formula to make cars, the formula to make light bulbs, the formula to construct houses . . . You can always tweak or change the details but the ‘core’ formula remains the same. Did you know that the airline industry has been using the same “tube and wing” design to construct airplanes for over 100 years? Why? “Tube and Wing” is a proven formula, the rest are just tweaks and changes (Type of aircraft engine, color of aircraft, number of seats etc)....

In this formula, a is a constant which expresses the overhead. For example, if a = 0.1 and n = 4, then P 3, so the performance of a multiprocessor consisting of 4 CPUs is approximately 3.

Spillways are familiar hydraulic structures built across a stream to control the water level. This chapter emphasizes the classification of weirs and spillways as well as the application of hydraulic formulas for designing their shape and dimensions.

The term "transition" is introduced whenever a channel's cross-sectional configuration (shape and dimension) changes along its length. Beside it, in the water control design, engineers need to provide for the dissipation of excess kinetic energy possessed by the downstream flow. Formulas for design calculation of transition works and energy dissipators are presented in this chapter
