The Root of Engineering

The roots of engineering project management began more than a century ago, with thought leadership by Taylor, Fayol, Gantt, and other industrialists seeking to define and improve the organization of work. The First Conference on Scientific... 

BOOK REVIEW The purpose of this exercise is to provide you with an opportunity to study, in depth, one book of your choice, subject to instructor approval, about design, the root of engineering. In so doing, you will be further introduced to the many facets of this sometimes creative and innovative process. Suggested tasks are ... 

The book begins with a brief history of engineering, which examines the roots of engineering and traces its development to the present day. The second chapter defines engineering and describes the functions and career paths for various branches of engineering. 

This special inspection problem concerns the detection of cracks in the root of turbine blades. The customer required a fast and reliable inspection on the wings", i.e. without dismounting the blades from the engine. 

As world supplies of petroleum are depleted, and as the Earth s population steadily increases, society will be forced to develop more efficient ways to make fertilizer. Genetic engineering offers a promising solution. There is a remarkable bacterium that lives in the roots of leguminous plants such as soybeans, peas, and peanuts. This organism can convert molecular nitrogen into ammonia. The plant and the bacterium have a... 

The synthesis is carried out in two phases. In the first phase a heuristic starting routine is used to generate an initial tree. It was found through experience that the pipes connected to the separation plant (the root of the tree) play a special role in the development of a tree. These pipes will be referred to as arms and the pipes connected to each arm its subtree. It is assumed that the number and location of the arms are specified as program input by the engineer. The two heuristic rules used by the starting routine are (i) efficient trees have low total pipe mileage (ii) efficient trees have nearly equal flow in their arms. Notice that the application of rule (i) by itself... 

The disciplines of engineering and quality control have long recognized the principles of root cause analysis. Some process safety tools for root cause analysis have been borrowed from these disciplines. For example, fault tree analysis was developed as an engineering tool, but its logic tree structure has been adapted to meet process safety requirements. 

Some fixed filtration systems are relatively inexpensive. For example, constructed wetlands and sand filters are generally the most successful methods of polishing the treated wastewater effluent from lagoons. These systems have also been used with more traditional, engineered primary treatment technologies such as septic tanks and primary clarifiers. In such constructed wetlands, the system utilizes the roots of plants to provide substrate for the growth of attached bacteria, which utilize the nutrients present in the effluents and for the transfer of oxygen. 

Fig. 9.34 Experimentally measured SBPs by cooling experiments as in Fig. 9.20 (PVC) and theoretically calculated SBP (solid curve). Circles and triangles denote two identical experiments. Solid circles and triangles denote solid-bed width at the barrel surface (maximum) open circles and triangles represent the solid-bed width at the root of the screw (minimum). Operating conditions as follows Tb = 375° N — 30 rpm P = 4300 psi G — 107.2 lb/h. [Reprinted by permission from Z. Tadmor and I.
