Thresholds and Expectation Thresholds [PDF]
Combinatorics, Probability and Computing, 2007 We consider relations between thresholds for monotone set properties and simple lower bounds for such thresholds. A motivating example (Conjecture 2): Given an n-vertex graph H, write pE for the least p such that, for each subgraph H' of H, the expected number of copies of H' in G=G(n, p) is at least 1, and pc for that p for which the probability that ...

ACM SIGMOD Record, 2023 Threshold queries are an important class of queries that only require computing or counting answers up to a specified threshold value. To the best of our knowledge, threshold queries have been largely disregarded in the research literature, which is surprising considering how common they are in practice.

Shell rupture threshold, fragmentation threshold, blake threshold [PDF]
IEEE Ultrasonics Symposium, 2005., 2006 The disruption of contrast agent microbubbles has been implicated in novel techniques for high-MI imaging and local drug delivery. At MI>0.6, microbubble fragmentation has been observed with thin-shelled agent (≈10 nm), and shell rupture with thick-shelled agent (≈250 nm).

Theoretical Computer Science, 2023 Abstract We consider the problem of sampling elements with some desired property from a large set, without testing the property of interest, but with the (probabilistic) assurance to have at least one match among the random sample. Like in ranked set sampling, we consider an infinite population under study, whose properties of interest are too ...

MANAS: Journal of Engineering, 2023 Multiple choice exams appear as the most common method used to measure student success in education systems in Turkey and around the world. Evaluation of multiple choice exams is usually done by optical form reading systems using expensive optical forms ...

Thresholds versus fractional expectation-thresholds [PDF]
Annals of Mathematics, 2021 Proving a conjecture of Talagrand, a fractional version of the 'expectation-threshold' conjecture of Kalai and the second author, we show for any increasing family $F$ on a finite set $X$ that $p_c (F) =O( q_f (F) \log \ell(F))$, where $p_c(F)$ and $q_f(F)$ are the threshold and 'fractional expectation-threshold' of $F$, and $\ell(F)$ is the largest ...

Mathematics, 2021 Object segmentation is a widely studied topic in digital image processing, as to it can be used for countless applications in several fields. This process is traditionally achieved by computing an optimal threshold from the image intensity histogram ...

Journal of Research of the National Institute of Standards and Technology, 2014 A digraph whose degree sequence has a unique vertex labeled realization is called threshold. In this paper we present several characterizations of threshold digraphs and their degree sequences, and show these characterizations to be equivalent. One of the characterizations is new, and allows for a shorter proof of the equivalence of the two known ...

Royal Society Open Science, 2021 Many physiological, biomechanical, evolutionary and clinical studies that explore skeletal structure and function require successful separation of trabecular from cortical compartments of a bone that has been imaged by X-ray micro-computed tomography ...

IoT-Based Information System for Healthcare Application: Design Methodology Approach
Applied Sciences, 2017 Over the last few decades, life expectancy has increased significantly. However, elderly people who live on their own often need assistance due to mobility difficulties, symptoms of dementia or other health problems.
