Non-convex approach to binary compressed sensing [PDF]
We propose a new approach to the recovery of binary signals in compressed sensing, based on the local minimization of a non-convex cost functional. The desired signal is proved to be a local minimum of the functional under mild conditions on the sensing ...

Randomized Algorithms for Minimum Distance Localization [PDF]
The problem of minimum distance localization in environments that may contain self-similarities is addressed. A mobile robot is placed at an unknown location inside a 2 D self-similar polygonal environment P. The robot has a map of P and can compute visibility data through sensing.

A local minimum theorem and critical nonlinearities
In this paper the existence of two positive solutions for a Dirichlet problem having a critical growth, and depending on a real parameter, is established.

Minimum local analgesic concentration of local anaesthetics
The minimum local analgesic concentration (MLAC) model was first described in 1995. The idea was to develop a clinical model for local anaesthetic drugs, similar to that which was in routine use for inhalation anaesthetics, the minimum alveolar concentration (MAC).

The Determination Of Reddening From Intrinsic VR Colors Of RR Lyrae Stars [PDF]
New R-band observations of 21 local field RR Lyrae variable stars are used to explore the reliability of minimum light (V-R) colors as a tool for measuring interstellar reddening.

Simple PTAS's for families of graphs excluding a minor [PDF]
We show that very simple algorithms based on local search are polynomial-time approximation schemes for Maximum Independent Set, Minimum Vertex Cover and Minimum Dominating Set, when the input graphs have a fixed forbidden minor.Comment: To appear in ...

Road Pavement Damage Detection Based on Local Minimum of Grayscale and Feature Fusion
In this work, we propose a road pavement damage detection deep learning model based on feature points from a local minimum of grayscale. First, image blocks, consisting of the neighborhood of feature points, are cut from the image window to form an image

TIVC: An Efficient Local Search Algorithm for Minimum Vertex Cover in Large Graphs
The minimum vertex cover (MVC) problem is a canonical NP-hard combinatorial optimization problem aiming to find the smallest set of vertices such that every edge has at least one endpoint in the set.

Minimum error sound source localization [PDF]
A novel approach to the problem of computing the direction of arrival (DOA) of a sound source using a two-element microphone array is presented. Typically, the DOA is computed by peak picking from the resulting cross-correlation function. In order to improve such estimates it is usually desirable to pre-filter the signals prior to cross correlation ...

On minimum locally $n$-(arc)-strong digraphs [PDF]
Let \(n\geq 1.\) A digraph \(D\) is called \(n\)-strong (\(n\)-arc-strong) if any removal of fewer than \(n\) vertices (arcs, respectively) from \(D\) results in a nontrivial strong digraph. A digraph is called locally \(n\)-strong (locally \(n\)-arc-strong) if the neighborhood of each vertex is \(n\)-strong (\(n\)-arc-strong, respectively).
