The approach can be easily implemented in any finite volume scheme and there is no limitation concerning the density ratio between layers.
The occurrence of complex operational deflection shapes (ODS) was identified as the main limitation concerning the disturbance rejection of the active system.
Recycled materials are not generally included in the quoted examples because they are usable in nearly all applications if there is no limitation concerning the considered article to be manufactured in the countries of production, commercialization, and use.
An adaptive control is first proposed to stabilize the vertical vehicle displacement and thus to improve the ride comfort and to guarantee other suspension requirements (e.g., road holding and suspension space limitation) concerning the vehicle safety and mechanical constraints.
Another important limitation concerning the phosphoenrichment methods is that mainly phosphopeptides from highly expressed proteins within cells can be purified, while the ones from phosphorylated proteins with low level expression (e.g. kinases) do not bind so well to those resins.
But in some cases, for example, in space application, in nuclear engineering, etc. there is not allowed to use high flow velocity of coolant – gas (due to vibration danger) or to apply high mass rate of coolant – liquid (due to limitation concerning weight or mass).
An important limitation concerning the analysis of data should be acknowledged.
However, the origin of these cells from human embryos causes their major limitation concerning tissue availability and standardization of the graft.
A possible limitation concerning the representativeness of our sample of patients participating in the focus group interviews is the overrepresentation of young patients.
As a limitation concerning the reliability of the extraction process we have to indicate that only 20% of articles were independently double checked.
The questionnaire assessing knowledge about chronic low back pain was newly developed for our purposes and is therefore not standardized measure, which bears another limitation concerning our measurements.
