Counting Gaps in Binary Pictures [chapter]

Valentin E. Brimkov, Angelo Maimone, Giorgio Nordo
2006 Lecture Notes in Computer Science  
An important concept in combinatorial image analysis is that of gap. In this paper we derive a simple formula for the number of gaps in a 2D binary picture.  ...  The number of gaps characterizes the topological structure of a binary picture and is of potential interest in property-based image analysis.  ...  of gaps in a binary picture in terms of its free vertices and edges.  ...

Models for the Formation of Binary and Millisecond Pulsars

D. Bhattacharya
1996 Symposium - International astronomical union  
Under the name "binary and millisecond pulsars" are grouped a number of radio pulsars, forming roughly 10% of the known pulsar population, which distinguish themselves on three counts:— Short spin period  ...  — Low magnetic-field strength— Presence of an evolved binary companion  ...  If the initial orbit is wide enough, with orbital period larger than ~1 year, then according to the conventional picture the neutron star would escape complete spiral in, and will be left in a tight binary  ...

A Novel Convex Relaxation for Non-binary Discrete Tomography [chapter]

Jan Kuske, Paul Swoboda, Stefania Petra
2017 Lecture Notes in Computer Science  
We present a novel convex relaxation and a corresponding inference algorithm for the non-binary discrete tomography problem, that is, reconstructing discrete-valued images from few linear measurements.  ...  reconstructions, we propose a joint formulation that addresses both problems simultaneously, resulting in a tighter convex relaxation.  ...  Number of instances where duality gap < 1 (optimality).  ...

Detection of fine-scale relationships between species composition and biomass in grassland

M. Kertész, B. Lhotsky, I. Hahn
2001 Community Ecology  
Since information statistical functions applied require binary data, we transformed NDVI data into one or several binary variables.  ...  We found that not only dominant species but subordinate gap species were also associated to high biomass, although the strength of association varied across scales.  ...  Henebry, and Beáta Oborny for their contribution in elaborating the novel methodology applied, and for comments on the draft.  ...

Gender Poverty Gap: A Comparative analysis of India and Pakistan

Muhammmad Siddique, Misbah Nosheen
2021 Review of Economics and Development Studies  
Findings of the paper suggest that there is gender poverty gap in Pakistan. Both India and Pakistan are suffering from poverty.  ...  Head count poverty is high in both countries but India has managed to lift more people out of multidimensional poverty. The paper recommends to design targeted oriented policies reduce gender poverty.  ...  Researches rigorously used this approach to have a clear picture of poverty.  ...
