Widening with thresholds via binary search

Sol Kim, Kihong Heo, Hakjoo Oh, Kwangkeun Yi
2015 Software, Practice & Experience  
WIDENING WITH THRESHOLDS VIA BINARY SEARCH The definition of the join operator for D immediately follows from the ordering definition.  ...  In this paper, we propose a technique to reduce the worst case by log N , by employing a binary search in the process of applying threshold values.  ...  Widening with Thresholds via Binary Search Our technique differs from the standard widening-with-thresholds technique in two ways. Widening Operator First, we use a different widening operator.  ...

Range Analysis of Binaries with Minimal Effort [chapter]

Edd Barrett, Andy King
2012 Lecture Notes in Computer Science  
Yet the lack of structure in binaries limits the effectiveness of classical range analyses based on widening.  ...  Since source code is unavailable, security audits necessarily occur at the binary level.  ...  This is called widening with thresholds [6] yet it requires the thresholds to be specified a priori.  ...

2011 IEEE Journal of Solid-State Circuits  
An adaptation scheme based on nested linear search is implemented to control the distributed threshold adjustment circuit.  ...  To improve input sensitivity in both RZ and NRZ reception, the receiver incorporates a limiting amplifier with a distributed threshold adjustment circuit.  ...  Once reached the closest code, check whether 2nd TA has overflow or underflow. 2) If 2nd TA has not overflow or underflow, continue with 3rd TA, and linear search for the criteria, and finish the search  ...

Merging binary black holes formed through chemically homogeneous evolution in short-period stellar binaries

Ilya Mandel, Selma E. de Mink
2016 Monthly notices of the Royal Astronomical Society  
This means that this channel is competitive, in terms of expected rates, with the conventional formation scenarios that involve a common-envelope phase during isolated binary evolution or dynamical interaction  ...  This slowly enriches the entire star with helium, preventing the build-up of an internal chemical gradient.  ...  The authors acknowledge the Leiden Lorentz Center workshop "The Impact of Massive Binaries Throughout the Universe".  ...

Ultracompact AM Canum Venaticorum Binaries from the Sloan Digital Sky Survey: Three Candidates Plus the First Confirmed Eclipsing System

2005 Astronomical Journal  
Both binary components are thought to be degenerate (or partially so), likely with mass-transfer from a helium-rich donor onto a white dwarf, driven by gravitational radiation.  ...  Limited time-series CCD photometric follow-on data have been obtained for three of the new candidates from the ARC 3.5m; most notably, a 28.3 minute binary period with sharp, deep eclipses is discovered  ...  This leads to a decreasing binary period until, at periods of a few minutes mass transfer begins, which subsequently widens the binary.  ...

FSpH: Fitted spectral hashing for efficient similarity search

Yong-Dong Zhang, Yu Wang, Sheng Tang, Steven C.H. Hoi, Jin-Tao Li
2014 Computer Vision and Image Understanding  
With more parameters Fourier function also fits data well. Thus with Sigmoid function and Fourier function, we propose two binary hashing methods: SFSpH and FFSpH.  ...  Spectral hashing (SpH) is an efficient and simple binary hashing method, which assumes that data are sampled from a multidimensional uniform distribution.  ...  Those real-values can be converted into binary codes via thresholding.  ...

2021 Electronic Commerce Research and Applications  
While recommendations are associated with a 29% increase in firm revenue, relevance of such recommendations potentially boost revenue by a significant 30%.  ...  The key finding is that the firm must always show recommendations to shoppers in the high state above a certain price or value threshold.  ...  Interestingly, as the gap between the high priced option that the consumer samples via search and the low priced recommendation widens,V decreases at a slightly slower rate.  ...
