Thinking, effect

Before carrying ont collaborative learning method let us join activity, survey is done to evaluate the presentation, communication, and interpersonal skills of students. For this the survey questions are gathered from various sources and survey was done when students are free from academic load, so that they think effectively and provide valid input toward the survey. 

One of the most effective ways to think about optimization is to visualize how a system s response changes when we increase or decrease the levels of one or more of its factors. A plot of the system s response as a function of the factor levels is called a response surface. The simplest response surface is for a system with only one factor. In this case the response surface is a straight or curved line in two dimensions. A calibration curve, such as that shown in Figure 14.1, is an example of a one-factor response surface in which the response (absorbance) is plotted on the y-axis versus the factor level (concentration of analyte) on the x-axis. Response surfaces can also be expressed mathematically. The response surface in Figure 14.1, for example, is... 

An emphasis on critical thinking. Critical thinking is encouraged through problems in which students are asked to explain why certain steps in an analytical procedure are included, or to determine the effect of an experimental error on the results of an analysis. 

As a device for describing the effect of temperature on solution nonideality, it is entirely suitable to think of Eq. (8.115) as offering an alternate notation which accomplishes the desired effect with p and as adjustable parameters. We note, however, that the left-hand side of Eq. (8.115) contains only one such parameter, x, while the right-hand side contains two p and . Does this additional parameter have any physical significance ... 

Like e, t is the product of two contributions the concentration N/V of the centers responsible for the effect and the contribution per particle to the attenuation. It may help us to become oriented with the latter to think of the scattering centers as opaque spheres of radius R. These project opaque cross sections of area ttR in the light path. The actual cross section is then multiplied by the scattering efficiency factor optical cross... 

A cost-effective layout that provides for easy operabiUty and quick turnarounds is often designed by someone with a background in the piping discipline. This is most likely because of their abiUty to think in three dimensions and their familiarity with visualizing three-dimensional piping (see Piping systems). 

We just cannot expect situations like golf clubs and tennis rackets for all consumer products because all products do not have those same built-in characteristics of the competitive edge. When we consider a car, we must be realistic and acknowledge that the car must have a price low enough for people to afford. Think back to the days of Henry Ford he made a car that could be sold for about 250, so that everyone could afford to have one. This affordability was the real beauty of his mass-production techniques. Everyone could afford to have a car, and then almost everyone did have one. In contrast, before Henry Ford, only the rich could afford an automobile. As soon as we get to the trade-off where composite materials will effectively compete in the automotive market place, we will see tremendously broader applications, but there are problems along the way. The manufacturing cost must be improved in order for those applications to ever come about. 

Where an effective informal system exists and is followed, the issue is one of style, not substance. A facility or unit may have a strong safety culture and sound safety practices, but its managers lack the habit of form documentation, or simply don t think it is important. Assuming that safety performance meets applicable standards, you will probably assign cases like these a relatively low priority, compared with other noncompliance situations. Cases like these are also often the easiest to fix since the fundamentals are already in place, what s required is simply to formalize the informal system by preparing and implementing documentation procedures. 

The classification structure for PIFs used in this chapter is based on the model of human error as arising from a mismatch between demands and resources which was described in Chapter 1, Section 1.6 (Figure 1.6). In this model demands were seen as requirements for human performance which arise from the characteristics of the process environment (e.g., the need to monitor a panel or to be able to fix a seal in a flange) and the nature of the human capabilities to satisfy these demands (e.g., skills of perception, thinking, and physical action). These demands are met by the individual and group resources of personnel and the extent to which the design of the task allows these resources to be effectively deployed. Where demands exceeded resources, errors could be expected to occur. 

Senior managers must consider a whole range of issues before deciding whether to support a new initiative. You must think as broadly as possible about the benefits that could be generated by integration. You don t want to leave out the one benefit that would have persuaded a key manager. We have already covered improvements in efficiency and effectiveness. Other possible benefits are ...
