Model scalability

The actuation model obtained in Section 5.3.1 is an infinite-dimensional transfer function. All parameters in the model are already fundamental material parameters and actuator dimensions except the double-layer capacitance C and the resistance R. Scaling laws for C and R can be further derived to obtain a fully scalable model. In particular, G is proportional to the area A of polymer/electrolyte interface. The resistance R can be obtained as a function of material resistivity and dimensions using a transmission line model [Fang et al. (2008d)]. Fig. 5.5 shows the experimental verification of the scaling laws for C and R, respectively. 

The scalability of the model has been validated experimentally. Fig. 5.6(a) shows the measured and model-predicted quasi-static tip force output versus tip bending displacement under a constant actuation voltage, for three samples with width of 3.5 mm but different lengths. Fig. 5.6(b) shows the same for another set of three samples with width of 6 mm. From Fig. 5.6, good agreement can be seen between the measurements and the model predictions for both sets of samples. 

We have also conducted experimental validation under dynamic inputs for both the admittance model and the full actuation model. For example. Fig. 5.7 shows the admittance spectra for two different actuator samples, with dimensions of 30 x 5 mm and 40 x 5 mm, respectively. For both

Some of the stand-alone programs mentioned above have an integrated modular 3D visualization application (e.g., ChemWindow —> SymApps, ChemSketch —> ACD/3D Viewer, ChemDraw —> Chem3D). These relatively simple viewers mostly generate the 3D geometries by force-field calculations. The basic visualization and manipulation features are also provided. Therefore, the molecular models can be visualized in various display styles, colors, shades, etc. and are scalable, movable and rotatable on the screen. 

Scale down the model to design a pilot plant that is scalable upward and that will address the most significant uncertainties in the model of the full-scale facility. 

The consequence of moving consciously toward this model will be the provision of a robust and scalable IT infrastructure and systems able to cope with exponentially growing data mountains that will need to be integrated and shared, accessed and mined in the most effective way. It will also require formidable computing power and sophisticated algorithms to be able to simulate both organs and whole body systems to reduce expensive failures in the clinic and predict much earlier the pharmacokinetic and pharmacodynamic properties and toxicological and efficacy profiles of molecules in pharmaceu-... 

As a starting point let us be faithful to the history of the subject and try a simple physical model due to (Johnston and Hecht, 1965) if the inhomogeneous EPR line reflects a distribution in g-values, then the anisotropy in the linewidth should be scalable to the anisotropy in the g-value. In other words, the analytical expression for g-anisotropy in terms of direction cosines, between B and the... 

Horizontal slices The technical architecture model should not be just a paper exercise. Instead, slices of the architecture model should be prototyped in a horizontal fashion where each slice helps complete the end-to-end communication paths but does not introduce new end-user functionality. Nonfunctional requirements—throughput, scalability,... 

Corporate support for Incubators Work was not withdrawn as the technology bubble burst, because Incubators Work as a collective entity reliably produced outputs such as education, social connections, and role models. This left individual entities such as Tunity Technologies, Vientity, and Scalable Systems free to search for viable niches, disciplined by the need to win external sources of funding. 

The catalyst and particulate filter models were developed individually with different university partners. They are described in the following sections. A key issue for all models is robustness and scalability as the applications range from passenger cars to heavy-duty commercial vehicles. The models are physical and chemically based, consisting of a transport model for heat and mass transfer phenomena in the monolith in gas and solid phases, cf. Fig. 6. The monolith reactor modeling is discussed in more detail in Section III. 

Insofar as the scale-up of pharmaceutical liquids (especially disperse systems) and semisolids is concerned, virtually no guidelines or models for scale-up have generally been available that have stood the test of time. Uhl and Von Essen [54], referring to the variety of rules of thumb, calculation methods, and extrapolation procedures in the literature, state, Unfortunately, the prodigious literature and attributions to the subject [of scale-up] seemed to have served more to confound. Some allusions are specious, most rules are extremely limited in application, examples give too little data and limited analysis. Not surprisingly, then, the trial-and-error method is the one most often employed by formulators. As a result, serendipity and practical experience continue to play large roles in the successful pursuit of the scalable process. 

A comprehensive study on the scalability of optimized small-scale microwave protocols in single-mode reactors to large-scale experiments in a multimode instrument has been presented by Kappe and coworkers [26]. As a model reaction, the classical Biginelli reaction in acetic acid/ethanol (3 1) as solvent was rim in parallel in an eight-vessel rotor system of the Anton Paar Synthos 3000 synthesis platform (Fig. 8) on a 8 x 80 mmol scale [26]. Here, the temperature in one reference vessel was monitored with the aid of a suitable probe, while the surface temperature of all eight quartz reaction vessels was also monitored (deviation less than 10 °C, see Fig. 16). The yield in all eight vessels after 20 min hold-time at 120 °C was nearly identical, resulting in an overall amount of approximately 130 g of the desired dihydropyrimidine. 

PyMOL is useful for viewing molecules and proteins. Because it is an open source architecture, in principal, it is much more scalable for custom applications than closed source software. Although the project has relatively a limited numbers of applications at this early stage, it is envisioned to eventually become a frill molecular modeling platform. Currently it is primarily a visualization package. Three main use cases are currently envisioned first, to visualize molecule (sdfile) or protein (pdf file), second to create a publication quality figure (static content), and third to enable one to use Pymol as one does Powerpoint for generating movies.

HCS assays have also been described using whole zebrafish embryos (Peterson et al 2000) and other multicellular models such as multinucleated myotubes from differentiated C2C12 mouse cells. These assays clearly proved interesting and novel ways to measure biological activity and despite probable scalability issues, they represent a potential new wave of image-based assays using more complex cellular models.
