Résumé. Le principe d’un ordonnancement coopératif selon une modélisation multi-agents résulte du rapprochement des domaines de l’Ordonnancement et de l’Intelligence Artificielle Distribuée. Le travail que nous présentons dans ce papier a pour objectif l’étude de l’adéquation des métaheuristiques avancées dans un SMA dans le cadre de la résolution d’un problème d’optimisation bien défini qui es...

This research demonstrates how a combination of two-way shape memory alloy (SMA), low-temperature liquid epoxy cure composites, and fibre reinforced plastic (FRP) may be utilised to create novel reversible actuator with built driven functionality. The novelty this work is that the can reverse its original mounted on different customized structures. strategy based knowledge SMA wires manufacturi...

background: spinal muscular atrophy (sma) is the second most common lethal autosomal recessive disease. it is a neuromuscular disorder caused by degenerative of lower motor neurons and occasionally bulbar neurons leading to progressive limb paralysis and muscular atrophy. the smn1 gene is recognized as a sma causing gene while naip has been characterized as a modifying factor for the clinical s...

spinal muscular atrophy (sma) is an autosomal recessive neuromuscular disorder characterized by degeneration of spinal cord anterior horn cells, leading to muscular atrophy. sma is clinically classified into three sub-groups based on the age of onset and severity. the majority of patients with sma have homozygous deletions of exons 7 and 8 of the survival motor neuron (smn) gene. the purpose of ...

Spinal muscular atrophy (SMA) is a genetic disorder which affect nervous system and is characterized with progressive distal motor neuron weakness. The survival motor neuron (SMN) protein level reduces in patients with SMA. Two different genes code survival motor neuron protein in human genome. Skeletal and intercostal muscles denervation lead to weakness, hypotony, hyporeflexia, respiratory fa...

Nickel-Titanium (NiTi) based shape memory alloy (SMA) wires are already often used in industrial actuator applications. Their high energy density allows to build light-weight systems with forces using small installation spaces. Combined the biocompatibility of NiTi, a huge field applications can be covered by SMA actuated systems. In like emergency brakes or switch disconnectors, which require ...

Shape memory alloys (SMAs) are being increasingly applied as thermally driven actuators. The commercially available SMA elements, however, frequently contain stress risers, either due to internal or surface defects the required component shape. Stress risers represent a potential danger for preliminary fatigue failure of such actuators but its actual mechanism is not very clear. This paper pres...
