Thinking

We might think that we can find all the structural options by inspection, at least all of the significant ones. The fact that even long-established processes are still being improved bears evidence to just how difficult this is. 

Based on a series of briefs published in the Economist in 1984, this important new book makes the key issues of contemporary economic thinking accessible to the general reader. 

Creativity and lateral thinking can work together for managers in developing new products or ideas Edward de Bono shows how. 

Increasingly, maintenance engineers think in terms of the performance and maintenance of equipment over the whole life of the field. This is often at the centre of the decision on capex-opex trade-offs for example spending higher capex on a more reliable piece of equipment in anticipation of less maintenance costs later in the life of the equipment. 

To simplify further discussion we would like to present in this section the four characteristics of NDT inspection which we think are of the most influence on the (options for) choice of any technique for automated interpretation of the data. 

We are sure that with this system we have developed a powerful tool to eliminate the shortcomings of manual inspection as discussed in the beginning of the article. We are also sure that this automatised test is not suitable in all applications. However, where there are many details to be tested and where these can be handled automatically, we think AMPl may be a competetive alternative which improves both the quality of inspection and the working environment. 

The required acoustic verifications depend on what the probe is made for. If the probe is used as an angular scamiing system with a fix set of elements, then we think it is only needed to characterize the array behavior with a few selected time delay laws to isolate the angular steering capability and the foeusing capability as explained before. 

The characterization of probe contributes to understanding the probe behaviour and gives the probe features as well. We have illustrated though different examples how to manage to limit the measurements to what is strictly necessary. We think that many things are still to do either to simplify with automatic process system existing procedures or to imagine different tests. 

Here is the raster scan of the s o we were discussing. Let me knowwhsl you think. 

One could think of the standard norm to define the distance between two signals Z, and Ziacquired during two successive inspections ... 

From the variation of contact angle with SAM composition in Fig. X-3, what do you think the measuring liquid is What would the plot in Fig. X-3 look like if, say, n-decane were used instead ... 

Why do you think the Cassie equation Eq. X-27 might work better than Eq. X-28 for predicting the contact angle as a function of surface polarity ... 

In a series of tests a car is brought to a certain speed, then braked by applying a certain force F on the brake pedal, and the deceleration a is measured. The pavement is dry concrete, and force Fq is just sufficient to cause skidding. Sketch roughly how you think the plot of a versus F should look, up to F values well beyond Fq. 

The character tables of these groups are given in table Al.4.6 and table Al.4.71. If there were no restriction on pemuitation symmetry we might think that die energy levels of the H2 molecule could be of any one of the following four syimnetry... 

There has been phenomenal expansion in the range of experiments coimected with light-molecule interactions. If one thinks of light as an electromagnetic (EM) wave, like any wave it has an amplittide, a frequency and a phase. The advent of the laser in 1960 completely revolutionized the control over all tluee of hese factors. The amplittide of the EM wave is related to its intensity current laser capabilities allow... 

The approach outlined here will describe a viewpoint which leads to the standard calculational rules used in various applications to systems in themiodynamic (themial, mechanical and chemical) equilibrium. Some applications to ideal and weakly interacting systems will be made, to illustrate how one needs to think in applying statistical considerations to physical problems. 

This is the result for monatomic fluids and is well approximated by a sum of tliree Lorentzians, as given by the first tliree temis on the right-hand side. The physics of these tliree Lorentzians can be understood by thinking about a local density fluctuation as made up of tliemiodynamically independent entropy and pressure fluctuations p = p s,p). The first temi is a consequence of the themial processes quantified by the entropy...
