Ultrasound elasticity imaging (UEI) is a noninvasive method for characterizing mechanical properties of soft tissue. This technique potentially provides important feedback for making treatment decision for advanced tendinopathies, such as posterior tibial tendon dysfunction (PTTD). Highly variable lateral strain along the length of the tendon has been observed during human experiments. To better understand...
Most of morphing aircrafts control the flight attitude by the deformation of aircraft wing, however morphing UAV is not limited to the deformation of the wing. This paper studies cyclic variable pitch propeller system which can generate control torque. According to mathematical model of cyclic variable pitch propeller based on propeller blade element theory, the study analyzes the principle and researches...
Posterior tibial tendon dysfunction (PTTD) is a common degenerative condition leading to a severe impairment of gait. There is currently no effective method to determine whether a patient with advanced PTTD would benefit from several months of bracing and physical therapy or ultimately require surgery. Tendon degeneration is closely associated with irreversible degradation of its collagen structure,...
A distributed permutation flow shop scheduling problem (DPFSP) is an NP-hard problem recently put forward in shop scheduling sphere. Exact algorithms for a DPFSP's solution can be extremely computationally costly. This paper proposes to apply an electromagnetism-like mechanism (EM) algorithm as a heuristic solution method to a DPFSP. To fit into the discrete domain of a DPFSP, modifications to the...
This paper presents a new topology optimization method using hybrid genetic algorithm, namely GAOC, using the evolutionary mechanism of the genetic algorithm (GA) and the interpolation scheme of optimality criteria method (OC). In GAOC, the optimality criteria method is used to initialize the genetic population, and GA is then applied to the global search in the fixed design domain. In so doing the...
