Semi-captive Asian elephants (Elephas maximus) engaged in forestry activities Myanmar account for 20% of all captive and semi-captive the world, are important both conservation elephant populations. Understanding moving behavior is required to sustain them. Our specific goals 1) determine range during free time, 2) hourly distance skidding when off duty. Three were fitted with handheld global n...

The negative influence of timber harvesting on the forest environment is reflected through damage to residual trees, regeneration, and soil. Considering that skidding, a popular extraction method, can cause substantial severe remaining stand, aim this research was determine trees during skidding by an LKT 81T cable skidder, including oxen bunching. conducted in eastern Bosnia Herzegovina, uneve...

In the current paper was approached braking system of tricycles for controlled skidding, which are used by lovers extreme sports. The complete modeling such a tricycle has been performed and its improved great performance better braking. Also, simulation tests were using finite element to achieve best constructive variant brake disc.

The main topic of this thesis is how to realistically model driver behavior in computer simulations of safety critical traffic events, an increasingly important tool for evaluating automotive active safety systems. By means of a comprehensive literature review, it was found that current driver models are generally poorly validated on relevant near-crash behavior data. Furthermore, competing mod...

Many patents have suggested that spinning the aircraft wheel before touchdown would lessen tyre wear as indicated by landing smoke and rubber deposites on the runway caused by skidding wheel at the point of impact. In this paper, the required torque to spin the aircraft wheel at approach speed has been calculated using ANSYS Workbench CFX, which is used to determine the wheel aerodynamic forces...

In the Shafaroud forest, logging operation is generally performed by using selective cutting methods. Chainsaw and cable skidder are two main forest machines for harvesting of this forest. However, forest harvesting operations result in serious residual stand damage during felling, winching and skidding operations in this forest. Residual stand damage resulting from selective cutting was asses...
