This book provides a concise introduction to the physical foundations of the electro-discharge technology and applies it to the drilling of wells, the demolition of reinforced concrete objects, and the cutting of cracks in rocks and concrete. The electro-physical basis of this technology and the technical implementation of using spark discharge as a “working tool” in the above-mentioned con…
This book analyzes the most important achievements in science and engineering practice concerning operational factors that cause damage to concrete and reinforced concrete structures. It includes methods for assessing their strength and service life, especially those that are based on modern concepts of the fracture mechanics of materials. It also includes basic approaches to the prediction of …
This unique book provides a bridge between digital control theory and vehicle guidance and control practice. It presents practical techniques of digital redesign and direct discrete-time design suitable for a real-time implementation of controllers and guidance laws at multiple rates and with and computational techniques. The theory of digital control is given as theorems, lemmas, and propositi…
The study was conducted on the effect of w/b on SCC concrete with palm oil fuel ash (POFA). Variations of W/B used in the compositions of SCC were 0.325, 0.350, and 0.375. Meanwhile, the POFA used is 10% of cement total. The results showed that the variation of w/b and the use of POFA affected the workability of the concrete, that could be seen from the test of fresh concrete in the form of slu…
