Data collection is performed by using the combination of compressive sensing and score based load balancing algorithm. To make the energy efficient network, the score based load balancing algorithm finds the path for routing the data towards the destination. The sensor nodes are divided into clusters and each cluster has one cluster head depending on their energy. The compressive sensing compre...

Lattice boom used on the crawler crane are welded by slender high strength steel tubes. Many studies show that actual bearing capacity of high-strength tubes is higher than stability calculated according to specification. To obtain and apply it engineering practice, a series axial loading tests carried out two kinds 20Mn2 S890 their damage load. By handling test data, coefficient fitting correc...

The development of cracking in concrete structures leads to significant permeability and to durability problems as a result. Approaches to controlling crack development and crack width in concrete structures have been widely debated. Recently, it was recognized that a high-performance fiber-reinforced cement composite (HPFRCC) provides a possible solution to this inherent problem of cracking by...

Axial vibration effect of shell particles on dynamic stability of a cantilevered cylindrical shell under an axial follower force was addressed. In spite of free-ended shells, the reduced axial force under this effect cannot be derived analytically. Instead, an approximate method was proposed based on the fact that the static (and harmonic) axial deformation under an axial load in a free-ended b...

PURPOSE The study of axial loading is essential to determine the properties of intervertebral disc. The objectives of this work are (1) to quantify the mechanical properties of porcine lumbar intervertebral discs under static and cyclic compressive loading, and (2) to determine the parameters of a five-parameter rheological model for porcine and compare them with those obtained for human lumbar...

Using classical molecular dynamics and empirical potentials, we show that the axial deformation of single-walled carbon nanotubes is coupled to their torsion. The axial-strain-induced torsion is limited to chiral nanotubes-graphite sheets rolled around an axis that breaks its symmetry. Small strain behavior is consistent with chirality and curvature-induced elastic anisotropy (CCIEA)-carbon nan...

BACKGROUND Internal tibial rotation is a risk factor for anterior cruciate ligament (ACL) injury. The effect of restraining tibial rotation (RTR) to prevent ACL injury during single-leg landing is not well understood. We aimed to investigate the effect of impact load and RTR on ACL injury with respect to flexion angle. We hypothesized that RTR could protect the knee from ACL injury compared to ...

The spine play very crucial role in bearing body weight. The loads acting upon a vertebra are borne by vertebral bodies and facet articulations. The vertebra has a composite structure, composed of large trabecular bone surrounded by thin cortical bone. The cortical and trabecular components share the load when the vertebra undergoes axial loading. The distribution and transmission pathway of th...

Analytical relations between the critical buckling load of a functionally graded material (FGM) Timoshenko beam and that of the corresponding homogeneous Euler–Bernoulli beam subjected to axial compressive load have been derived for clamped–clamped (C–C), simply supported–simply supported (S–S) and clamped–free (C–F) edges. However, no such relation is found for clamped–simply supported (C–S) b...
