A Contact Dynamics algorithm is applied to simulate the failure of 2-dimensional granular steps. Focussing on one single value for both adhesive force threshold and contact friction, we track signature in cumulative displacement grains. The introduction a allows identification onset rapid formation corresponding shear band. latter gives access an estimation orientation. robustness measure thus ...

The requirements of the rules and regulations Classification Societies are based on assumption that during construction operation ships hull corrosion protection measures implemented according to standards other regulatory documents currently in force. For purposes designing ship structures, load components for different types have been obtained paper. There collected data relationship between ...

Landslides are serious and complex geological natural disasters that threaten the safety of people’s health wealth worldwide. To face this challenge, a landslide displacement prediction model based on time series analysis modified long short-term memory (LSTM) is proposed in paper. Considering data from different periods have values, weighted moving average (WMA) method adopted to decompose cum...

OBJECTIVE Among the countries of the Americas, Colombia has the highest level of deaths due to homicides and armed conflict. The objective of this research was to combine and contrast information from various sources on deaths due to violence in Colombia in order to identify major trends in violence in the country and to compare those trends with those in other nations of the Americas. METHOD...

a terrier came along. Through my binoculars, I saw the lapwing becoming increasingly anxious and, when the intruders were about 200 metres away, the bird ran off to trail a wing in front of them. The restrained dog clearly wanted to chase the injury-feigning bird and, had it been allowed to do so, would have been led well away from the nest. The lapwing's distraction would almost certainly have...

The aim of this study was to investigate the acute effect of vibration exercise (VbX) on repetitive horizontal jumping performance and to examine the duration of the rest interval between the horizontal jump sets following acute VbX. Fourteen track athlete males (age 20.8 ± 1.8 yr; height 1.80 ± 0.05 m; body mass 73.1 ± 7.5 kg) performed four conditions in a randomised order; (a) VbX with 1 min...

Inappropriate treatment of skier's thumb injuries has been reported to result in chronic painful instability, weakness of pinch, and arthritis. Therefore, surgical treatment is recommended for those fractures with 2 mm or more of displacement, or significant articular involvement with incongruency or rotation. The goal of surgery is restoration of anatomy with stable fixation. In this study we ...

OBJECTIVE To determine differences in strength and range of motion (ROM) between participants who exhibit medial knee displacement (MKD) during a squat that is corrected by a heel lift and those who do not. DESIGN Case control. SETTING Sports medicine research laboratory. PARTICIPANTS Thirty-seven healthy subjects (control, 19; MKD, 18) with no lower-extremity injury in the past 6 months ...

Current "spatio-temporal energy" models of how we perceive pattern motion have been very successful in helping us to understand the mechanisms of motion perception. Although they have been supported by a large number of physiological and psychological studies, they have so far not provided a complete explanation for a number of results. These results emerge from experiments concerned with predi...

The Observer Video-Pro is a system for collecting, managing, analyzing, and presenting observational data. It integrates The Observer software with time code and multimedia hardware components. It extends the functionality of a conventional real-time event recording program in various ways. Observational data can be collected, reviewed, and edited with synchronized display of the corresponding ...
