Graph matching: relax or not?
We consider the problem of exact and inexact matching of weighted undirected graphs, in which a bijective correspondence is sought to minimize a quadratic weight disagreement. This NP-hard problem is often relaxed as a convex quadratic program, in which the space of permutations is replaced by the space of doubly-stochastic matrices. However, the applicability of such a relaxation is poorly und...
متن کاملThe Effect of Cervical Spine Isometric Contract-relax Technique on Hamstring Extensibility
Objectives: To re-investigate the effect of a cervical isometric contract-relax technique on hamstring extensibility and examine the duration of any treatment effect.Methods: Forty asymptomatic participants were randomly assigned equally to either an experimental or control group. Both groups underwent pre and post hamstring extensibility measurements using passive knee extension with the thigh...
متن کاملEffect of submaximal contraction intensity in contract-relax proprioceptive neuromuscular facilitation stretching.
OBJECTIVE To determine if submaximal contractions used in contract-relax proprioceptive neuromuscular facilitation (CRPNF) stretching of the hamstrings yield comparable gains in hamstring flexibility to maximal voluntary isometric contractions (MVICs). METHOD Randomised controlled trial. A convenience sample of 72 male subjects aged 18-27 was used. Subjects qualified by demonstrating tight ha...
متن کاملAcute stretch perception alteration contributes to the success of the PNF "contract-relax" stretch.
CONTEXT Some researchers have suggested that an alteration of stretch perception could be responsible for the success of the contract-relax (CR) stretch, a stretch technique derived from proprioceptive neuromuscular facilitation (PNF). OBJECTIVE This study was conducted to determine if the alteration of the stretch perception is a possible explanation for the range of motion (ROM) gains of th...
متن کاملNeural Relax
We propose a new self-organizing algorithm for a feedforward network inspired to an electrostatic problem that turns out to have intimate relations with information maximization.
