Directives and Statistics Feedback

2017
In 11g there was a feature called Cardinality Feedback. This reoptimized (hard parsed) a query if the Cardinality Estimate of the final result was more than a certain factor out from the actual result. This was a nice simple feature that was easy to understand. If you saw this note at the end of an execution plan, you knew that Cardinality Feedback had

Direct design of feedback SD systems

2000
Let us have the feedback sampled-data system shown in Fig. 17.1, with the notation and assumptions of Section 11.1–11.5, so that $$\begin{array}{*{20}{c}} {{{W}_{d}}(s) = \frac{{b(s)}}{{a(s)}},} & {{{\mathcal{D}}_{{FM}}}(T,s,0) = \frac{{{{e}^{{ - sT}}}\chi (s)}}{{\alpha (s)}}} \\ \end{array}$$ (17.1) where F(s) = G(s)R(s).

Modeling direct positive feedback between predators and prey

Theoretical Population Biology, 2004
Predators can have positive impacts on their prey through such mechanisms as nutrient mineralization and prey transport. These positive feedbacks have the potential to change predictions based on food web theory, such as the assertion that enrichment is destabilizing.

Direct process feedback in extrusion-based 3D bioprinting

Biofabrication, 2019
A major limitation in extrusion-based bioprinting is the lack of direct process control, which limits the accuracy and design complexity of printed constructs. The lack of direct process control results in a number of defects that can influence the functional and mechanical outcomes of the fabricated structures.

Bistable optical spatial device using direct optical feedback

Optics Letters, 1978
Analysis and implementation of a set of optically controlled optical flip-flops on the surface of a liquid-crystal spatial- light modulator (SLM) are presented. The elementary system consists of a pair of image elements on the SLM whose input and output are coupled to each other by purely optical means.

Minimal feedback vertex sets in directed split‐stars

Networks, 2005
AbstractIn a graph G = (V,E), a subset F ⊂ V(G) is a feedback vertex set of G if the subgraph induced by V(G)\F is acyclic. In this article, we propose an algorithm for finding minimal feedback vertex sets of directed split‐stars. Indeed, our algorithm can derive an upper bound on the size of the minimum feedback vertex set in directed split‐stars ...
