In the Structural Domain, hardware subsystems (e.g., separate data paths and controllers) represent the processes of the Behavioral Domain. These hardware subsystems are thought of as operating concurrently with each other, although their internal operation may include both sequential behavioral and statement-level parallelism. 

However, these languages were designed for simulation and their use for synthesis requires ignoring certain simulation-oriented assumptions. Among others, VHDL sequential behavior statements are assumed to execute in zero time A key to the acceptance of Algorithmic and Register-Transfer Level synthesis will be the development of appropriate languages based on the needs of synthesis and simulation. 

Sequence, An edge (n, n e P means that 2 is executed after n. In figure 2, edge (8,9) is an example of required sequential behavior. 

The input to the Workbench is a mixed behavioral and structural description. In Verilog, sequential behavior is described with the always statement, combinational behavior is described with the continuous assignment statement assign), and hierarchical structural is described with module definitions, and module and gate instantiations. For the purposes of the Workbench, the synthesis tools treat the always statement as a single process description of the behavior to be synthesized into a structural data path and controller. For each always statement, a separate controller and data path is generated. 

A sequential function chart (SFC) describes graphically the sequential behavior of a control program. More sophisticated than the information flow chart, it is derived from two earlier approaches, Petri Nets and Grafcet (David, 1995 Desrochers and Al-Jaar, 1995). SFCs consist of steps that alternate between action... 

Extraction of hemiceUulose is a complex process that alters or degrades hemiceUulose in some manner (11,138). Alkaline reagents that break hydrogen bonds are the most effective solvents but they de-estetify and initiate -elimination reactions. Polar solvents such as DMSO and dimethylformamide are more specific and are used to extract partiaUy acetylated polymers from milled wood or holoceUulose (11,139). Solvent mixtures of increasing solvent power are employed in a sequential manner (138) and advantage is taken of the different behavior of various alkaUes and alkaline complexes under different experimental conditions of extraction, concentration, and temperature (4,140). Some sequences for these elaborate extraction schemes have been summarized (138,139) and an experimenter should optimize them for the material involved and the desired end product (102). 

The behavior of elements (toxicity, bioavailability, and distribution) in the environment depends strongly on their chemical forms and type of binding and cannot be reliably predicted on the basis of the total concentration. In order to assess the mobility and reactivity of heavy metal (HM) species in solid samples (soils and sediments), batch sequential extraction procedures are used. HM are fractionated into operationally defined forms under the action of selective leaching reagents. 

Richards, et. al. s idea is to use a genetic algorithm to search through a space of a certain class of cellular automata rules for a local rule that best reproduces the observed behavior of the data. Their learning algorithm (which was applied specifically to sequential patterns of dendrites formed by NH4 Br as it solidifies from a supersaturated solution) starts with no a-priori knowledge about the physical system. R, instead, builds increasingly sophisticated models that reproduce the observed behavior. 

In the following four studies, the Pb and J parameters are to be varied systematically to reveal their influences on the properties recorded. The reader should now select, sequentially, the following four sets of rules, following the instructions for this in Chapter 10. Compare the behaviors of the molecules in each case with those observed for the neutral conditions prevailing in Example 2.2. Do the ingredients tend to move toward or away from one another Do they tend to stick together or separate ...

Our whole task from a clinical perspective includes (1) delineation of the patterns of behavioral pathology induced both during the active stimulant abuse phase and the phases of withdrawal (2) description of the sequential profile of underlying structural and functional pathology at each of the clinical phases and (3) an attempt to elucidate the relationship between (1) and (2). In addition, an understanding of the pharmacological and other parameters sufficient and necessary for inducing components of the stimulant syndrome is clearly needed and can be obtained only from basic laboratory studies. 

Recently [63], we studied the behavior of two-enzyme system catalyzing two consecutive reactions in a macroheterogeneous medium (modified Lewis cell). The system consisted of lipase-catalyzed hydrolysis of trilinolein and subsequent lipoxygenation of liberated fatty acids (Fig. 3). Our approach compared the kinetic behavior of coupled enzymes in the Lewis cell with the sequential study of separated phenomena presented before ... 

Consider the sequential transition Xi —U X2 —X3. One can assume Markovian behavior and add the second entropy separately for the two transitions. In view of the previous results this may be written... 

Figure 29 (Qin and Liu, 1982) shows the behavior of individual particles above the distributor recorded by video camera of small clusters of particles, coated with a fluorescent material and spot-illuminated by a pulse of ultra violet light from an optical fiber. The sequential images, of which Fig. 29 just represents exposures after stated time intervals, were reconstructed to form the track of motion of the particle cluster shown in Fig. 30. Neither this track nor visual observation of the shallow bed while fluidized, reveal any vestige of bubbles. Instead, the particles are thrown up by the high velocity jets issuing from the distributor orifices to several times their static bed height.
