The problem with composite indicators | BMJ Quality & …

Threats arising from issues with underlying measures and data. Composite indicators, by their nature, obscure details about the underlying measures, yet problems in the latter can render the composite meaningless. At minimum, the underlying measures must represent valid measures of quality. To achieve this, they need to be adequately and ...

Problem with Composite products

 · But the the other issue is remaining, it might be an issue for the developer of the Composite Product, but I´ll take a chance and hoping you might have a solution for this as well. The problem is: The final price doesn’t get summed up after the customer have made his choices – it is still in 0.

The problem with composite indicators

12 · Abstract . Bundling individual quality measures into composite indicators is now a widespread practice, but is prone to multiple problems. They include lack of transparency in reporting, use of flawed methodological approaches, weaknesses in how measures are standardised and combined, and failure to describe statistical uncertainty of scores or rankings.

Corrosion problems solved with composite

13 · Composite materials can be used in a wide variety of environments due to their service range. Workers can apply them in temperatures from +10°C to +50°C. Composites are stable at temperatures from –50°C to +150°C and can be built to contain pressures up to 120 bar.

Our Love/Hate Relationship with Flowable Composites

25 · When the first flowable composites were introduced in 1996, 1 nobody was quite sure what to do with them, but we could see the definite advantages of an injectable material that instantly wets the tooth structure. What we have learned over time is that the more we manipulate composites, the more problems we can experience.

Composite Defects and Their Detection

25 · In composite structures, defects are most often in the form of either disbonds or delaminations in the plane of the material, or porosity. The reason for favoring ultrasound inspection is that it is very sensitive to these types of defect commonly found in composites. It is also one of the few methods available for detecting porosity and it
