Different types of structural analyses, first order elastic, second order elastic, first order plastic, and plastic zone analysis, were used to simulate the behaviour of 3 portal frames constructed from cold-formed rectangular hollow sections. All analyses underestimated the magnitude of the deflections of the frame mainly due to the non-inclusion of flexible joint behaviour. A second order ine...

tendons are frequently targets of injury in sports and work. whether nonsteroidal anti-inflammatory drugs (nsaids) have beneficial effects on tendon healing is still a matter of debate. this study was conducted to evaluate effects of flunixin meglumine (fm) on tendon healing after experimentally induced acute trauma. twenty eight adult male new zealand white rabbits were subjected to complete t...

To monitor the stress state and yield capacity of H-beams across their entire service process, a real-time monitoring method based on energy signal response ceramic piezoelectric sensors is proposed in this paper. The applied to conduct loading experiments under different load values web heights. Then, amplitude signals two working conditions are compared analyzed, finite element analysis resul...

Tailored gradation in elastic–plastic properties is known to offer avenues for suppressing surface damage during normal indentation and sliding contact. In tribological applications, sliding contact analysis provides a more representative mechanism for fundamental understanding and design as it offers a tool to test materials under conditions of controlled abrasive wear. However, no such study ...

Surgical treatment for traumatic, anterior glenohumeral instability requires repair of the anterior band of the inferior glenohumeral ligament, usually at the site of glenoid insertion, often combined with capsuloligamentous plication. In this study, we determined the mechanical properties of this ligament and the precise anatomy of its insertion into the glenoid in fresh-frozen glenohumeral jo...

A SLIP line theory governing states of incipient plane flow at the yield point load is developed for anisotropic rigid/plastic materials which exhibit a reduced yield criterion, governing states of plane flow, that depends only on the deviatoric parts of the in-plane stress tensor. It is shown that every homogeneous, incompressible material which complies with the principle of maximum plastic w...

A three years study on precision farming in cotton in central Greece showed serious infield variability of yield and soil physical and chemical properties. Yield mapping constitutes the starting and ending point of the whole process chain in a precision farming system. Yield mapping was performed for three consecutive years in the same cotton fields of central Greece in a wide range of cotton v...

ÐWe observe that typical programs exhibit highly regular read-after-read (RAR) memory dependence streams. To exploit this regularity, we introduce read-after-read (RAR) memory dependence prediction. This technique predicts whether: 1) A load will access a memory location that a preceding load accesses and 2) exactly which this preceding load is. This prediction is done without actual knowledge ...

We measure Web performance bottlenecks in home broadband access networks and evaluate ways to mitigate these bottlenecks with caching within home networks. We first measure Web performance bottlenecks to nine popular Web sites from more than 5,000 broadband access networks and demonstrate that when the downstream throughput of the access link exceeds about 16 Mbits/s, latency is the main bottle...
