Practice Problems Note: Unless you are confident in your ability to determine direct conversion factors, such as cm to km, it is highly recommended to convert to the standard unit. This allows one to relate cm to m, and then m to km. ...
Here, we adopt a simplified analysis, one of the assumptions being incompressible flow. In addition, the walls of the turbine annular duct are assumed to be coaxial cylindrical surfaces of revolution, long enough so that we may neglect the disturbing end effects upon the flow patterns about the...
Our new embeddings have improved the running time of many important problems from least squares regression to low rank approximations, which are workhorses of statistical analysis. For instance, our running time for least squares regression is nearly optimal unless one can avoid generic matrix ...

To be useful in analysis a dimensional attribute needs these key characteristics: • Descriptive, so business people and those designing the BI applications can understand it. • Complete, with no missing values. • Unique, because it’s critical that values are uniquely identifiable. • Val...
This post draws your attention to recent, top-shelf, research flagging the risks around spurious factor analysis. While formal solutions are still pending there are couple of heuristics we can use to detect possible problems. Continue reading ...
First, the price coef- ficients represent own and cross-price elasticities, which are often focal economic objects in the analysis of market structure and pricing/promotion schedules. Second, the functional form is simple and admits tractable estimators of all model parame- ters. Third, the ...
Ultra-structure analysis: The ultra-structure analysis of ALS was performed using scanning electron microscopy (SEM). Section were prepared and fixed in 2.5% (v/v) Gluteraldehyde in 1 × PBS and further subjected to dehydration using graded series of ethanol (50%, 75%, 80%, 95% and 100...
reflexive strategy use. Figure4displays the proportion of participants in each block whose data was best fit by the reflexive, one of the three reflective or the random responder model separately by explicit dimension prime condition. A mixed effects modeling analysis was conducted with the reflexive...
The analysis showed a sufficient amount of collagen-1 secretion from the construction promoting cell–cell adhesion, formation and maturations. Fig. 5 illustrates the different combination of scaffold-based and scaffold-free approaches for constructing 3D bio-structures. Both approaches need to maintain...
