Further research on the limitations, maintenance and implementation costs of model based controllers in this application would be worthwhile.
Given Gi-annakis work on wavelet approach, and its limitations in complexity and implementation, we suggest in this context of wideband channels sensing, a detector using an algebraic approach to detect and estimate the local spectral irregular structure, which carries important information on the frequency locations and power spectral densities of the subbands.
Each strategy has its own advantages and limitations regarding implementation and the interpretation of results, all of which affect reliability [ 15, 33].
In addition, we collected qualitative data to facilitate the interpretation of the findings from this quantitative data analysis and to identify strengths and limitations in design and implementation of GMIS.
Although all these markers have obvious advantages and some disadvantages too, there are several limitations regarding interpretations and implementation of obtained findings in risk stratification among CHF patients [10].
We observe that while the measures taken by the State, since 1949, show a growing commitment to sustainable management of the region, there are limitations in the design and implementation of concrete actions for their protection.
The reduction in malaria incidence and prevalence after a year of MTAT was observed despite a number of limitations in the design and implementation of the intervention.
Unfortunately, despite evidence that early mobility is safe and effective, there are limitations to its adoption, and implementation worldwide remains low [ 103, 104].
39 The following factors will be considered: limitations in the design and implementation of available studies suggesting a high likelihood of bias, indirectness of evidence, unexplained heterogeneity or inconsistency of results, imprecision of results and high probability of publication bias.
