In the presented work model and experiments of compliant robots with piezo actuators are carried out. The robot is designed to perform automatic injection of cells in the range of 10-30 μm. A kinematics model of serial-parallel structures is presented. Pseudo rigid body approach is used, where the elastic joints are modelled as revolute joints. Models for tension of parallel structures with ela...

The demand for large antennas in future space missions has increasingly stimulated the development of deployable membrane antenna structures owing to their light weight and small stowage volume. However, there is little literature providing a comprehensive review and comparison of different membrane antenna structures. Space-borne membrane antenna structures are mainly classified as either para...

This study presents novel research on the seismic behavior of self-centering reduced beam section (RBS) connections in steel structures. Unlike traditional moment frames that concentrate non-elastic deformations energy dissipation devices, innovative RBS utilize post-tensioning techniques to restore structure its pre-earthquake condition. By significantly reducing residual deformations, these o...

To study the effect of local corrosion prestressed steel strands on shear failure mode and bearing capacity concrete beams, unilateral in four post-tensioning (PC) beams are corroded, test PC performed. Moreover, a simplified calculation method for with diagonal bars is proposed considering cross-sectional reduction bars, degradation mechanical properties, damage concrete. Results shows that cr...

In the last years, attention to seismic strengthening of existing buildings has increasingly grown, especially since a huge number national incentives been allocated for deep renovation building stock. Various research pushed toward new solutions suitable account entire life cycle retrofit solution and that would overcome main barriers renovation, which are, example, need relocate inhabitants. ...

abstract traumatic rupture of the distal biceps tendon is rare. conservative treatment can result in reduced flexion and supination power with reduced function. this case report emphasizes the need for prompt surgical treatment and describes the possible complications of delayed surgical intervention.

results in 41 of 186 (22%) hands, the palmaris longus tendon was absent and absence of the fifth flexor digitorum tendon was noted in eight (4.30 %). the median surface area in the hands without palmaris longus was meaningfully lower than the hands with it (p = 0.025), while the difference in the median surface area was not statistically significant with regard to presence of the fifth flexor d...

A sustainable environment can be achieved by strengthening the existing building to avoid new construction and replacing materials with long-lasting such as a fiber-reinforced polymer (FRP). Using post-tensioned (PT) FRP systems has proven an effective technique in structure decreasing cracks deformability. In this study, 3-D finite element model was built investigate flexural behavior of compo...

BACKGROUND Intratendinous injections may have important effects on the properties of collagen microarchitecture, morphology, and subsequent mechanical properties of the injected tendon. The purpose of this study was to examine the effects of intratendinous PRP injections; the injectant retention within tendons, the distribution of intratendinous injectant, and whether intratendinous injection o...
