Evaluation tools simulated tests

Dynamic models operationally define and quantify the flows of patients, which represent opportunities in a given marketplace. In general, the patient flow component recreates the structure and magnitude of patient movements within a simulation environment representing an indication marketplace. This type of operational examination of market dynamics becomes a useful commercial evaluation tool. In addition, it can help inform and test key marketing strategies considered for an NCE s brand plan designed to maximize that potential. 

For many years test chambers and cells belong to the most important tools for the simulation of indoor related conditions and for the evaluation of emission rates. It can be assumed that their application will become even more important in the near future. Moreover, powerful kinetic models are now available that help to understand emission characteristics of sources. The current trend to develop devices en miniature brings us to the borderline between emission and content analysis. It will be interesting to see new chamber designs and intelligent applications for indoor related studies. 

Finally, as it is not possible to experimentally test all the various kinds of surface textures within actual solar cell configurations, it can be useful to use numerical simulations, in order to evaluate the best combination of surface textures and roughness for both front and back TOO layers. The method usually applied for such simulations is to take the main optical properties of each layer of the solar cell (absorption, thickness, haze factor, ADF, surface roughness,. ..), and then to put them all together in order to compute the quantum efficiency curve of the resulting solar cell. Such a task of optically simulating solar cells is very complex and beyond the scope of the present chapter. However, it is important to note here that a numerical simulation is always only an imperfect tool and can in no way fully replace experimental work and measurements on actual solar cells. 

Substantially better FCC forecasts can be made with the MST simulation conditions, making this test a very useful tool for catalyst and feedstock evaluations. 

Notwithstanding the possibility of doing detailed simulations with bench or pilot scale riser reactors, the traditional Micro Activity Test (MAT) remains the main tool for basic FCC research and catalyst and feedstock evaluation and monitoring.

GAPD s approach consists of materials characterization and behavior modeling, combined with component analysis and risk integration tools. Uniaxial and biaxial stress states will be evaluated to develop models for fast fracture, slow crack growth, creep deformation, and oxidation. The accuracy of the methodology will be verified by testing simulated components under stress and temperature conditions representative of gas turbine engine operation. 

Color labs are outfitted with laboratory size equipment that simulates the larger machines used for production internally and by their customers. Typical processing equipment found in the lab are small extruders, two-roll mills, ban-burry mills, and media mills. Small rotational, injection and blow molding machines are used to duplicate the customers process. Instruments and computers are required for testing physical properties and color. Most labs have a computer-controlled color measuring system and a light booth to evaluate color. The spectrophotometer with computer is initially used to assist in colorant formulation and later as a quality control (QC) tool to provide certification of the quahty of match to standard. The light booth provides a standardized set of conditions to visually observe color and appearance.
