Identification and distance measures of measurement apparatus.
We propose simple schemes that can perfectly identify projective measurement apparatuses secretly chosen from a finite set. Entanglement is used in these schemes both to make possible the perfect identification and to improve the efficiency significantly. Based on these results, a brief discussion on the problem of how to appropriately define distance measures of measurements is also provided.
متن کاملIdentification and Assessment of Human Error during the Process of Operating Various Types of Fire Apparatus
Background and Aim: Firefighting is a difficult and dangerous job. This job requires decision-making and speed of action in critical situations. Such conditions increase the probability of human error in the firefighting activities. Setting up fire apparatus as the first step of emergency response is associated with high criticality. The purpose of this study is identification and assessment th...
متن کاملStudy Of Some Distance Measures For Language And Encoding Identification
To determine how close two language models (e.g., n-grams models) are, we can use several distance measures. If we can represent the models as distributions, then the similarity is basically the similarity of distributions. And a number of measures are based on information theoretic approach. In this paper we present some experiments on using such similarity measures for an old Natural Language...
متن کاملNew distance and similarity measures for hesitant fuzzy soft sets
The hesitant fuzzy soft set (HFSS), as a combination of hesitant fuzzy and soft sets, is regarded as a useful tool for dealing with the uncertainty and ambiguity of real-world problems. In HFSSs, each element is defined in terms of several parameters with arbitrary membership degrees. In addition, distance and similarity measures are considered as the important tools in different areas such as ...
متن کاملComparative study of histogram distance measures for re-identification
Color based re-identification methods usually rely on a distance function to measure the similarity between individuals. In this paper we study the behavior of several histogram distance measures in different color spaces. We wonder whether there is a particular histogram distance measure better than others, likewise also, if there is a color space that present better discrimination features. S...
