Accomodated process system. It is found in the previous sections that the hierarchical network of the SPEED is constructed based on subtargets and looping mediators. In actual process systems, however, there may be subsystems to supply donor reactants or exergy-donating utilities such as electricity and steam. Such subsystems cannnot be classified into the previous groups because the product of the target in the subsystem appears in the couplers of the main process system. Therefore they are called the accomodated process system and treated separately. Since each accomodated system has a target, we may construct a SPEED for each accomodated subsystem. 

Monolithic dry gels with a hierarchical network structure and an interconnected, multilevel pore system were obtained after drying (Fig. 2). Even within this small pH regime from pH = 6 to 2, the macroscopic gel morphology can to a large extent be controlled. In addition, the choice of glycol has a decisive influence on the architeture of the network. 

The polymer template was removed in two different ways, by toluene extraction and by pyrolysis, which resulted in very different types of gold replicas. In the first case the nanoparticles retained their shape, which led to a hierarchical network structure with nanopores between the nanoparticles and macropores from the templating polymer spheres. When the latex was removed by calcination at 300 °C, the gold nanoparticles fused to a dense metal matrix with only macropores. 

The practical synthesis of hierarchical networks can be achieved in various ways quite commonly colloid particles are used for templating the macropores, while meso- and micropores can be introduced by phase separation of block copolymers or surfactants. 

In general two fimctionahzation approaches are available either (1) direct functionalization of the macro- and mesopores during the hierarchical network formation or (2) postfimctionahzation of the porous material via the... 

The multiechelon hierarchical network configuration, which considers the options of both direct shipment from manufacturing plants to customers and indirect shipment through either master distribution centers or regional warehouses, may be an intriguing subject for further studies.

The nanocoating of PPy on natural cellulose fiber was performed without disrupting the hierarchical network structure of individual fibers [245]. Since pyrrole was hardly adsorbed onto a cellulose surface, this approach was based on the adsorption of the growing polymer chain from the solution and on the subsequent immobilization to form thin film. The conformation of the PPy chain was parallel to the surface of the cellulose fiber, because the corresponding oligomer is adsorbed parallel to the surface and further polymerized in the lateral direction. 

The design and its environment are modeled as procedural functional units in a hierarchical network, communicating by level-sensitive, asynchronous protocols. 

The hierarchical network of ProcVhdl matches the component instantiation concept for structural descriptions in Vhdl, with communication carried out by simple Vhdl signals. This match would in fact be possible for most simulator-based languages, and is mainly a consequence of the choice of asynchronous communication protocols in the hardware model this model places very few restrictions on the actual low-level signal behavior. 

Most expert systems are rule-based, consisting of hierarchical networks of IF-THEN rules. Rules are fired by searching the conclusions first (backward chaining) or by searching the premises for the co-occurence of certain values (forward chaining). When the search conditions are satisfied, the rule is applied. Applying a rule may access another rule, query the user, or take some action. Rule-based systems are said to reflect procedural knowledge of the expert. 

To build large hierarchical networks. Routers are used to create the backbone network itself. 

To take part in or gain access to a larger hierarchical network such as the Internet. 

Structure-forming technologies to direct sol-gel polymerization and achieve high analytical specificity, controlled micro and meso-porosity, and even hierarchical networks with multimodal pore size distribution, are reviewed in the last section of this account. 

We cannot judge at this point whether the importance of small mesoporosity for charge transport is really general or specific to the investigated film, but the authors have clearly demonstrated that films with bimodal and trimodal pore-size distributions are useful for electrochemists, because such combinations may at times alter the obtained electrochemical response in unexpected ways. We anticipate that multimodal pore-size distribution film-modified electrodes and mem-branes (i.e., hierarchical networks) will become widespread in electrochemical sensing, catalysis, and energy storage applications.

Natural cellulose, a polysaccharide, is a linear natural polymer of fS-(l — 4)-d-glucopyranose possessing abundant surface hydroxyl groups that form abundant inter- and intramolecular hydrogen bonds (Figure 2.16). The polymer chains accumulate into elementary fibrils (diameter 1.5-3.5 nm), and bundle to microfibrils (nanofibers, diameter tens to hundreds of nanometers), further form randomly interconnected hierarchical networks of microfibrillar fibers (microfibers, diameter in the micrometer scale or larger), resrdting in the familiar bulk cellulose... 

Our interface is open to appropriation towards any number of instances that involve the representation of multiple conceptual networks. Here we describe one instance of use for a folklore group that seeks to allow users to search and view their database of traditional folk artists in the state of Indiana. The interface couples a spatial network with a conceptual, hierarchical network. The spatial network highlights counties and cities based on whether they contain folk artists. Each artist will be contained in a county. The county represents the number of artists by becoming a darker color. If a user clicks on a county, the artists will then be laid out according to city. Opposite the map, a conceptual network constructs a hierarchical structure of crafts that are represented by the artists. 

The pair of images in fig. 1 shows what happens when a user searches based upon the hierarchical network of crafts. In this instance the user selects the craft wood then the sub-craft intarsia . On the left, this action filters down the counties on the map to show only those that have people associated with the four sub-crafts within wood . In the right image of fig. 1, the available sub-crafts have reduced to intarsia based upon the user s selection. In this case there is only one person shown as a node off of intarsia . Accordingly, only one county is represented. From this, it is clear which county James Adkins resides. 

The complexity of a centralized algorithm grows in a nonlinear way with the number of robots. Moreover, this solution forces all mobile robots to communicate continuously with the supervisor thereafter, robots need either to move closely to the supervisor location, or to set up a hierarchical network (Antonelli, Ar-ricchiello, Chiaverini, Setola, 2006). In both cases, some constraints over team mobility are imposed to guarantee that, at each moment, at least one communication-path from any robot to the supervisor exists.
