Network modification

To estimate experimentally the actual decrease in Vg in the crazes over Ve in drawn but unfibrillated polymer, one can use the X and DZ data. In addition the perforated sheet crazes in very thin (100 mm thick) PS films should involve httle entanglement network modification and X in these crazes can be used to estimate Idz for this polymer. Since 7-dz x (ve) and x (vg) ... 

From several applications, it is convenient to describe much of the above systems as resulting from the modification of the parent porous materials by a second component. In this sense, one can separate network modification, network building, and network functionalization processes. Network modification exists when the final structure of the parent material is modified as a result of its combination with the second component, thereby resulting in the formation of a new system of links. Network building occurs when the material is formed by assembling the units of both components. Finally, functionalization involves the attachment of selected molecular groups to the host porous material without modification of its structure.

Total harmonic distortion (THD) level in a power network is directly related to the characteristics of the network itself. In the case of a mine under construction, these characteristics do change as equipment installation progresses. Someday, a network modification will shift a natural resonance on or within vicinity of a higher level drive harmonic. Normally unnoticed, this particular harmonic will resonate, pushing the THD beyond acceptable limits. 

The glass ceramics have densities around 2.5 g/cm, therefore, the penetration depth of space electrons and protons is only a few millimetres. Network modifications resulting in changed material properties affect the performance of glass ceramics only if they are exposed directly to space and mounted on the outside of the spacecraft. However, in this case as above only the first millimetres of the glass ceramics are concerned. 

Figure 9 effectively shows the results of the double maximum storage discharge volume effect on the total gas volume availability in the network. Similar what-if type of analysis can be done for any element and parameter in the network in order to effectively plan network modifications and quantify various options in terms of security of supply. 

If a network has excess CO even after highest reuse indicated by the pinch point, opportunities for systan improvement can be further explored by network modifications. Modifications can consist of intfoducing demands to increase utilisation of existing source streams, removal of sources to decrease emissions or intfoduction of purification units. The general hierarchical decision making for the implonentation of modifications to achieve targets in the initial network and for further CO emissions reduction is summarised as follows (Manan and Wan-Alwi 2012) ...
