Global Command

The command workspace is an area of computer memory that is reserved for parameters you define from the command line in MATLAB. Each m-file has its own unique workspace, and this workspace does not communicate with the command workspace unless you make it happen. It is sort of like two of your friends having a disagreement they choose not to talk until a third party (you) defines a way to do so. There are two ways to set up the communication using the global command or calling arguments of the m-files. 

The second way to pass parameters is to use list the parameters in the function statement of the m-file. For example, the m-file

Step 1 The code called run volplot computes the specific volume for pressures from 1 to 31 atmospheres and then calculates the corresponding compressibility factor. The first statement in riinvolplot is a global command. The variables are identified, T, p, 1, and so on, and then assigned values. In other programs, such as specvol, the same global command is used, and these variables can then be accessed. See Appendix B for more mformation. 

Step 2 The m-file specvol is changed to use the global command, as shown in Eq. (2.34). 

Step 1 Here you use the global command in run equil eq global, set the variables, and repeat the global command in the function equil eq global. Then those variables are accessible to the function (see Appendix B for additional information). 

Step 3 When using the global command, you must be sure to use the global command in the command window (or a run program that runs in the command window), set the variables after the global statement, and then repeat the global statement in the function. If you do not follow these mles, MATLAB will inform you that it was asked for an undefined variable or function, and give you the m-file and line number where it appears. 

Step 2 Next, add the global command to the m-file, called rhs2. (Note you added a numerical identifier to both the calling program and m-file to help keep them straight.)... 

Step 4 Next, construct an m-file, ratel mass.m, to evaluate the right-hand sides of Eq. (8.45). This m-file is almost the same as that shown following Eq. (8.23), except that a global command is used so the parameters can be changed easily. The only significant change to this m-file from that used earlier is the use of fzero to find CAs, and then using CAs rather than CA to evaluate the rate of reaction.

If the code you wish to check is in an m-file, the first check is to see that all the parameters are passed correctly and have been set in the workspace available to the m-file. The easiest way to do this is to request that the m-file print all the variables you expect to be transferred to the m-file, at the start of the m-file, and check that they are correct. If a variable has not been set, MATLAB wiU give you an error message without running the code. It tells you the line and column where the undefined variable is. The problem is probably improper passing of parameters or incorrect use of the global command or, sometimes, a typing error.

The U.S. pharmaceutical and biotechnology industry continues to lead the world in innovation and product sales. It accounts for nearly 40% of global pharmaceutical sales [34]. This industry is in fact one of the few in which the United States retains a commanding global lead. If the twenty-first century is to become known as the biotech era and the new pharmaceutical century, it will be very important to the United States that this leadership position be retained. 

Another area of global-scale dimensions that is commanding increased attention is the potential impact of atmospheric trace gases and aerosol particles on climate, the subject of this chapter. Climate is the longterm statistical characterization of parameters describing what we commonly term weather, such as surface temperature. For example, the mean surface temperature with its associated variability over some time period, typically taken as 30 years, is one measure of climate. Thus, climate is distinguished from short-term, e.g., day-to-day, variations, which are typically referred to as weather. ... 

The first line of any SPICE netlist is the title line. It is used for documentation purposes only. The next few lines usually tell SPICE which analysis will be performed and what the bounds of that analysis will be. For example, we may be requesting a time domain analysis of a circuit (called a transient analysis). The information as to how long the waveform is and what increments and what section of it are of interest is defined in this section of the code. SPICE netlists generally have one function, command, or element per line (Fig. 2.1). Also defined upfront are global constants, subcircuits (models) used repeatedly in the main circuit, and instructions on which nodes are of interest in the final solution, though this structure is not mandatory. 

Several other formal features of Huxley s trance condition are of interest with respect to the analogy we have drawn with REM sleep dreaming. We first consider the relaxed posture, indicating a step on the path to cataplexy. In full-blown cataplexy, the assumption of a flaccid posture is associated with the inability to move on command and is thus similar to the active motor paralysis of REM sleep dreams. Anesthesia and amnesia were both present in Huxley s trance, although they tended to be selective, and when Huxley attempted to make them global, his trance deepened. Time distortion, a distinctive component of the orientational instability of dreams, was a robust aspect of Huxley s altered state. 

This code is typically called by a MATLAB command such as f luidbed(4000,. 4,. 9,1,1, 45/99,10 s8,10 sll,.4,.6,18,27,1,0,10), which uses a large time limit of 4000 dimensionless time units so that the individual solution curves of the IVPs have time to run to the global steady state at (0.17619, 0.72225, 0.86446). We do this with the original parameter data of p. 183, a controller gain of K = 10, and several different initial values. Since the value of K is greater than 4, the middle steady state with maximal x i> yield is both unique and (statically) stable.

The worldwide amino acids market amounts to about 5 billion. MSG and the animal feed additives, methionine and lysine, account for about 75 percent of this sales value. The other amino acids are used as precursors in pharmaceuticals, food additives, and animal feed. The worldwide demand for glutamic acid is about 800,000 tons/year, 300,000 tons/year for methionine, and 500,000 tons/year for lysine. Other significant amino acids such as aspartic acid, phenylalanine, threonine, and glycine, each have a worldwide market of about 10,000-20,000 tons/ year. Tryptophan and cysteine command a global market in the thousands of tons as well.

In chemical engineering, as well as in other scientific and technical domains, where one or more materials are physically or chemically transformed, a process is represented in its abstract form as in Fig. 1.1(a). The global process could be characterized by considering the inputs and outputs. As input variables (also called independent process variables , process command variables , process factors or simple factors ), we have deterministic and random components. From a physical viewpoint, these variables concern materials, energy and state parameters, and of these, the most commonly used are pressure and temperature. The deterministic process input variables, contain all the process variables that strongly influence the process exits and that can be measured and controlled so as to obtain a designed process output. 

The global ectoparasiticide sales for 1998 were 1.35 billion (Figure 14). As we have noted earlier, the new flea control agents, fipronil, imidacloprid and lufenuron, command a substantial slice of this. Despite concerns about environmental and worker toxicity, organophosphates are still major products in the livestock sector.
