At all points in a system, the static pressure is always equal to the original static pressure less any velocity head at a specific point in the system and less the friction head required to reach that point. Since both the velocity head and friction head represent energy and energy cannot be destroyed, the sum of the static head, the velocity head, and the friction head at any point in the system must add up to the original static head. This is known as Bernoulli s principal, which states For the horizontal flow of fluids through a tube, the sum of the pressure and the kinetic energy per unit volume of the fluid is constant. This principle governs the relationship of the static and dynamic factors in hydraulic systems. 

Predictive maintenance systems use two methods of detecting a change in the operating condition of plant equipment static and dynamic. Static alert and alarm limits are pre-selected thresholds that are downloaded into the microprocessor. If the measurement parameters exceed the pre-set limit, an alarm is displayed. This... 

Note that while a system s static complexity certainly influences its dynamical complexity, the two measures are clearly not equivalent. A system may be structurally rather simple (i.e. have a low static complexity), but have a complex dynamical behavior. (Think of the chaotic behavior of Feigenbaum s logistic equation, for example). 

The system will not be acceptable if, at any time during normal dynamic, static, or stress conditions, the pressure in the primary environments becomes less than zero or negative. 

Before considering instrumentation in some detail in later chapters, it will be helpful to outline the kinds of experiments that we wish to implement electronically. It is useful to characterize electroanalytical techniques as either static or dynamic. Static methods are philosophically akin to the passive observation mentioned earlier. They entail measurements of potential difference at zero current such that the system defined by the solid-solution interphase is not disturbed and Nernstian equilibrium is maintained. Although such potentiometric measurements (e.g., pH, pM) are of great practical importance, our focus here will be on the dynamic techniques, in which a system is intentionally disturbed from equilibrium by excitation signals consisting of a wide variety of potential and current programs. 

The selection of the most suitable instrument for a required measurement from a range of commercially available instruments necessitates the knowledge of certain important factors. These can be divided into the static and dynamic characteristics of the instrument. The dynamic properties of instruments are fundamentally no different from those of any other system or process and are described, therefore, by the analysis of system dynamics presented in Chapter 7. Static properties, which are specific to instrumentation, are discussed in this section. 

It is generally recognized that in order to analyze the stereochemical features of real systems (molecules, or groups of molecules and reactions) it is useful to abstract those features which determine the properties of interest and to represent them in terms of a single model system. It is possible to perform an isomorphic mapping of the essential stereochemical features of each of the real systems onto this model, and an equivalence relation will thus exist between the real systems. We shall say that any two systems whose static stereochemistry (structure, conformation) and conformational dynamics may be represented by the same abstract model exhibit stereochemical correspondence. 

First let us review static and dynamic electron correlation. Dynamic (dynamical) electron correlation is easy to grasp, if not so easy to treat exhaustively. It is simply the adjustment by each electron, at each moment, of its motion in accordance with its interaction with each other electron in the system. Dynamic correlation and its treatment with perturbation (Mpller-Plesset), configuration interaction, and coupled cluster methods was covered in Section 5.4. 

The nature of the static and dynamic properties of concentrated polymer systems is the focus of our work. We have already examined some static properties and are presently starting our study of the system dynamics. 

To improve the overall amount of analyte that is extracted, a flowing donor is often used i.e., the sample is pumped past the donor side of the membrane in a dynamic flow system. Also static systems with a stagnant donor are common, often with convective mixing by stirring. 

The effect of the shearing time, t, of the dynamic-static experiments was also investigated. Since could not be measured when it was shcater than the time for the DSC system to be equilibrated, the L was instead selected as an indicator of the... 

In the top-left corner of Fig. 5.56, a system s static structure is defined with its components, their (import and export) interfaces and their relationships. To describe the dynamic behavior of the system one or more interaction or collaboration diagrams (top-right corner of Fig. 5.56) may be used for example. Both specifications are restricted to the logical level, i.e. they strictly adhere to the concepts of modularity and encapsulation. 

Nab assays determine the potential to neutralize in vivo. However, these in vitro assay systems are static systems that do not take into consideration the dynamic interactions that occur in vivo (e.g., clearance of ADA-dmg immune complexes, equilibrium/affinity between drug/antibody/target). There are examples of Nab (even to endogenous protein) that have no/minimal impact on drug efficacy, pharmacodynamics, or adverse events [24,25], Thus, one shouldkeep in mind that whenNab assays are used, the results must be evaluated in the context of other clinical end points to determine their significance.
