Fully-integrated mode

During normal operation the flare valve is closed and the pressure in the gasifier is controlled through a by-pass valve at the booster compressor. Quite naturally is the gasifier a slow system concerning both pressure and temperature control. The output control of the gas turbine is completely different and it responds more or less instantaneously. Operation in the fully integrated mode made the pressure, temperature and gas quality in the system vary a bit when the gas turbine suddenly compensated for a small change in either parameter. 

Each of the above principles can be used in an instantaneous, semi-integrating or fully-integrating mode, but cost, sensitivity and convenience dictate preferences. A summary of favoured applications of methods and principles is given in Table 11-XVI. Several reviews of methods, instruments and applications have been published (Morrison et al., 1969, IAEA, 1974 Smith et al., 1976 Morse 1976 Dyck, 1979a Dyck 1979b). A more detailed description of each mode is presented below. 

As discussed previously, read time is often a bottleneck in the HCS process and will dictate upstream liquid handling processes unless a pause step (as with fixed cells) is included. Assays with many 384-well plates in live cell mode become difficult, even with a fully integrated robotic system, because the cell growth, cell plating, compound addition, and other steps require precise coordination with imaging that is often not worth the cost.

Integrated Raman systems can be classified as instruments designed for the research laboratory, for routine analysis, for process control, and for portable, field-deployable applications. Research laboratory instruments offer new and state-of-the-art capabilities in exchange for compromised reliability and frequent need for support from a Raman expert. Research laboratory instruments are extremely adaptable to address unanticipated measurement needs. Routine analysis instruments provide limited flexibility with good reliability. They are operationally simple and contain enough Raman expertise built in for technicians to carry out repetitive assays efficiently and reliably. Process control instruments are typically fiber optic Raman systems that have been hardened to perform in the more challenging environmental conditions typical of a chemical production facility. A process control instrument usually runs continuously in a fully automated mode. There... 

The second mode is a closed-loop simulation, where all system actions are fully integrated into the driver-vehicle control loop. A simulated warning, for example, is actually given to the driver, or an automatic braking results in a simulated deceleration of the vehicle. This mode allows a quantification of the effects of a particular system configuration on the frequency of accidents and on the resulting injury severities (using the injury probability models of Chap. 5).

The FPI principle can also be used to develop thin-film-coating-based chemical sensors. For example, a thin layer of zeolite film has been coated to a cleaved endface of a single-mode fiber to form a low-finesse FPI sensor for chemical detection. Zeolite presents a group of crystalline aluminosilicate materials with uniform subnanometer or nanometer scale pores. Traditionally, porous zeolite materials have been used as adsorbents, catalysts, and molecular sieves for molecular or ionic separation, electrode modification, and selectivity enhancement for chemical sensors. Recently, it has been revealed that zeolites possess a unique combination of chemical and optical properties. When properly integrated with a photonic device, these unique properties may be fully utilized to develop miniaturized optical chemical sensors with high sensitivity and potentially high selectivity for various in situ monitoring applications. 

In contrast to our preferred standard mode in this book, we do not develop a Matlab function for the task of numerical integration of the differential equations pertinent to chemical kinetics. While it would be fairly easy to develop basic functions that work reliably and efficiently with most mechanisms, it was decided not to include such functions since Matlab, in its basic edition, supplies a good suite of fully fledged ODE solvers. ODE solvers play a very important role in many applications outside chemistry and thus high level routines are readily available. An important aspect for fast computation is the automatic adjustment of the step-size, depending on the required accuracy. Also, it is important to differentiate between stiff and non-stiff problems. Proper discussion of the difference between the two is clearly outside the scope of this book, however, we indicate the stiffness of problems in a series of examples discussed later. So, instead of developing our own ODE solver in Matlab, we will learn how to use the routines supplied by Matlab. This will be done in a quite extensive series of examples. 

COS-7 or CHO cells (for initial transfection screening) or cells of therapeutic interest (e.g., dendritic cells and various cancer cells) at a confluence of 50%, grown in 96-well culture plates, were placed into the robot by the robotic conveyor. In a fully automated process, the robot removes the lid from the cell culture microtiter plate, dispenses lipoplexes into the wells (triplicates), replaces the lid and returns the plate to the incubator. After four hours, the cells are automatically retrieved, the cell monolayers are carefully washed using a special drop mode of the integrated plate washer, fresh medium is added, and the cells are incubated for further 42 hours before harvesting.
