The winding process of carbon fiber is not a new concept, but until now only few studies have been made in tensioning and on complex shapes. main purpose the article to analyze possibility conduct using two industrial robots connected as master slave, one realize other hold rotate mandrel, an own design automatic tool. To control system force transducer was implemented. measured used make traje...

Abstract Previous research has evidenced that by adding a ductile reinforcement on the tension side of glass beam, for instance adhesive bonding, its post-cracking behaviour and redundancy were improved, while an additional pre-stressing this further helped to increase initial cracking resistance. Past investigations used steel tendons or stainless strips, which required rather complex setups p...

Subject-specific tensioning of ligaments is essential for the stability knee joint and represents a challenging aspect in development finite element models. We aimed to introduce evaluate new procedure quantification ligament prestrains from biplanar X-ray CT data. model evaluation was performed by comparing predicted femorotibial kinematics with vitro response six cadaveric specimens. The diff...

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. ...

Cryogenically cooled components in infrared instruments designed by Utah State University's Space Dynamics Laboratory traditionally have been mounted on glass-epoxy composite (G-10) cylinders for thermal isolation. Ensuring adequate mechanical stiffness to withstand typical launch loads often compromises the desired thermal isolation and conduction parasitic heat loads become a concern. Beginni...

The "Docking Plus" technique for elbow ulnar collateral ligament (UCL) surgery is described in the following text and video. Depite the general success of UCL surgery, significant rates of retear and failure of return to competition persist. Hypothesized reasons for UCL surgery failure include insufficient graft strength (midsubstance tears), insufficient graft tensioning (functional UCL insuff...

Reconstruction of the lateral ulnar collateral ligament of the elbow is the primary treatment for recurrent symptomatic posterolateral rotatory instability. Although a number of lateral ulnar collateral ligament reconstruction techniques have been described, the docking technique has received general acceptance. In this technique, the graft is passed through a tunnel on the ulnar side and the 2...

BACKGROUND Posterior Cruciate Ligament (PCL) ruptures are common sports injuries. One of the key controversies in PCL reconstruction is whether double-bundle reconstruction provides biomechanical and clinical outcomes superior to single-bundle reconstruction. METHODS We performed a comprehensive search in multiple databases to evaluate the advantages of single-bundle or double bundle reconstr...

Paper introduces main characteristics and particulars of an innovative design for an Unmanned Surface Vehicle to autonomously launch and recover AUVs (Autonomous Underwater Vehicles) in open sea. The USV has an unconventional SWATH hull shape and in its smaller size version, it has dedicated hangar at midship that can host one medium size AUV, completely recovered onboard. The focus of this pap...
