Consequences control

These methods are efficient for problems with initial-value ODE models without state variable and final time constraints. Here solutions have been reported that require from several dozen to several hundred model (and adjoint equation) evaluations (Jones and Finch, 1984). Moreover, any additional constraints in this problem require a search for their appropriate multiplier values (Bryson and Ho, 1975). Usually, this imposes an additional outer loop in the solution algorithm, which can easily require a prohibitive number of model evaluations, even for small systems. Consequently, control vector iteration methods are effective only when limited to the simplest optimal control problems. 

The establishment of ionization equilibrium is the rate-determining step in this process and consequently controls the thickness of the wave front (Ref 6)... 

Shewhart control charts enable average process performance to be monitored, as reflected by the sample mean. It is also advantageous to monitor process variability. Process variability within a sample of k measurements can be characterized by its range, standard deviation, or sample variance. Consequently, control charts are often used for one of these three statistics. 

The structural aspects which determine the inherent capability of these acids to undergo ring closure, and which consequently control the course of the cyclization, are (a) the size of the ring formed (b) the reactivity of the aromatic nucleus, including the effect of substituent groups (c) steric considerations other than ring size. 

Mass spectrometry (MS) has been applied mainly for the on-line detection and quantification of gases such as p02, pC02, pN2, pH2, pCH4 and even H2S [282] or volatiles (alcohols, acetoin, butanediol). The detection principle allows simultaneous monitoring and, consequently, control of important metabolites. 

The translation of mRNA to protein concludes the gene expression cascade and links the proteome to the genome. Consequently, control of translation can be a direct and effective means to modulate the proteome [21, 30, 31]. In addition to transcript interactions with protein regulators, translation is also modulated by structural features or regulatory sequences appearing within the mRNA molecules. The 7-methylguanylate triphosphate nucleotidyl caps at the 5 end, poly-A tails, uORFs, and IRESs are examples of structures that affect the rate and efficiency of translation in eukaryotes [21]. 

The second method has been applied to cw CO lasers it relies on the fact that CO(t> = 0) and a number of other vibrationally cold gases preferentially deexcite lower vibrational levels of CO, where vibration-vibration energy exchange is closest to resonance [256, 257]. Consequently, controlled addition of these gases can make the populations in neighboring vibrational levels more suitable for laser action and can enhance the power output [258, 259],... 

The variation in So leads to the variation in the shape of the machined surface (Fig. 8). Consequently, control of machining parameters enables one to change the shape and dimensions of the machined surface. It is seen from (13) and Fig. 8 that decreasing the voltage and raising the TE feed rate allows one to decrease So and improve the reproduction of TE shapes on the WP. 

Consider again the stirred tank heater, but now under feedback control (Figure 5.5). Control loop 1 maintains the liquid level at a desired value by measuring the level of the liquid and adjusting the value of the effluent flow rate. Therefore, control loop 1 introduces a relationship between F and h. Similarly, control loop 2 maintains the temperature of the liquid at the desired value by manipulating the flow of steam and thus the flow of heat Q. Consequently, control loop 2 introduces a relationship... 

Another remarkable example is the recycle of energy developed in an adiabatic PFR for reactants preheating. Although the stand-alone PFR reactor is stable, in recycle it may become unstable. Consequently, control is needed to stabilise it. Moreover, the stabilisation depends on the design of the units involved in recycle. Section 13.6 develops more this issue. 

That behavior is of utmost importance because it allows a consequent control of the accumulation onto the different environmental compartments of soft flexible plastic items identified as commodities eventually released in the environment as a consequence of impolite civil behavior of the end users. 

The intramolecular electrostatic interactions play a very important role in the control of the conformation of a molecule and consequently control its chemical behavior. These interactions will be discussed first.
