Limited by our limitations

Our Color Vision is Limited

Two limitations of our knowledge of quality

This article develops a quality notion that is complementary to the system notion. As a major consequence, it becomes clear why quality can be measured only to a certain extend based on the issues of validity and incompleteness. First, there is an inherent conflict between the applicability and validity of quality measures and second, quality considerations almost always refer to high-dimension...

Networks and our Limited Information Horizon

In this paper we quantify our limited information horizon, by measuring the information necessary to locate specific nodes in a network. To investigate different ways to overcome this horizon, and the interplay between communication and topology in social networks, we let agents communicate in a model society. Thereby they build a perception of the network that they can use to create strategic ...

About the Limitations of the PS-limited Tofts Model

Introduction Compartment models are widely used to quantify physiological parameters such as capillary permeability, P, or extravascular extracellular fractional volume, ve [1]. Usually the extravasation of low-molecular-weight contrast media (CM) in dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) lead to intensity time curves. To these the respective compartment models are fitte...

Why Is Our Working Memory and Processing Capacity so Limited?

We show that spurious synchronization, as suggested by Luck and Vogel 6], is not suucient to explain the limited storage capacity of working memory. Instead we argue that the sharp breakdown of error free recall suggests a dynamic mechanism behind working memory. We summarize some suggestions for the dynamic basis of working memory and argue that the reason behind our limited processing capacit...
