Simultaneous engineering - meaning

In order to calculate the landslide stability for engineering application, a pore pressure calculation method which is based on the standard water level, is proposed in Japan (Figure 2). A concept of residual pore pressure is introduced, and it is defined as when the reservoir water level drops rapidly, the underground water cannot drop simultaneously, which means that the groundwater level lags the change of reservoir water level, in other... 

The application of the reverse Euler method of solution to a system of coupled differential equations yields a system of coupled algebraic equations that can be solved by the method of Gaussian elimination and back substitution. In this chapter I demonstrated the solution of simultaneous algebraic equations by means of this method and showed how the solution of algebraic equations can be used to solve the related differential equations. In the process, I presented subroutine GAUSS, the computational engine of all of the programs discussed in the chapters that follow. 

The paradoxical situation just described means that it is entirely possible for a science or an engineering student to have completed a course in physical chemistry and still not have any clear idea of what colloid and surface science are about. A book like this one is therefore in the curious position of being simultaneously advanced and introductory. Our discussions are often advanced in the sense of building on topics from physical chemistry. At the same time, we have to describe the phenomena under consideration pretty much from scratch since they are largely unfamiliar. In keeping with this, this chapter is concerned primarily with a broad description of the scope of colloid and surface science and the kinds of variables with which they deal. In subsequent chapters different specific phenomena are developed in detail. 

It has been recommended that torpedoes be loaded with charges hollowed in their forward ends. Advantage is taken of the Munroe effect in the routine blasting of oil wells, and, intentionally or not, by every explosives engineer who initiates an explosion by means of two or more electric blasting caps, fired simultaneously, at different positions within the same charge. 

The flow injection analysis (FIA) response curve is a result of two processes, both kinetic in nature the physical process of dispersion of the sample zone within the carrier stream and the chemical process of formation of a chemical species. These two processes occur simultaneously, and they yield, together with the dynamic characteristics of the detector, the FIA response curve. Simultaneous dispersion and chemical reaction have been studied in flow systems as used in chemical reaction engineering and in chromatography, and, therefore, the theories of these two areas are related to the theory of FIA. This is why most papers about FIA theory have adopted, as a starting point, the classical theory of flow in tubular conduits, with the intention of developing mathematical expressions for peak broadening, mean residence time, and fractional conversion of the analyte to a detectable product. 

The majority of modem gasoline fueled passenger cars is equipped with so-called closed-loop three-way catalysts to aftertreat their exhaust gases [1], The purpose of this system is to convert simultaneously carbon monoxide, hydrocarbons and nitrogen oxides by means of a precious metal based heterogeneous catalyst, whereby the engine s air-to-fliel-ratio is controlled to... 

Task network modeling was used by LaVine et al. (1995) to extend laboratory data and field data collected on one set of human tasks to predicting performance on similar tasks. The problem of extending laboratory or field human performance data to other tasks has plagued the human engineering community for years. We intuitively know that human performance data can be used to predict performance for similar tasks. However, often the task whose performance we want to predict is similar in some ways but different in others. The approach described below uses a skill taxonomy to quantify task similarity and therefore provides a means for determining how other tasks will be affected when exposed to a common stressor on human performance. Once functional relationships are defined between a skill type and a stressor, task network modeling is used to determine the effect of the stressor on performance of a complex task that simultaneously uses many of these skills.
