If two lines are cut by a transversal and the corresponding angles are congruent, the lines are parallel. The converse of the corresponding angles theorem is used to prove two lines are parallel if a pair of corresponding angles are known to be congruent. For example, look at the following ...
Now, dislocations in any material have a finite length, a typical magnitude (except in especially designed materials, see below) being ∼100 nm or less. In addition, dislocations are by no means static. They respond to an incoming elastic wave, i.e., to a phonon, by bowing out, and ...
No. It passes "action(file)" directly in the loop, so the directory transversal will continue on other threads in thread pool, and it can return immediately.And action(file) looks like this:prettyprint 复制 (f) => { // Exceptions are no-ops. try { // Do nothing with the data ...
Second, many systems repeat a kinematically preprogrammed trajectory [17,21], making them static and non-parameterizable. Finally, while end-effector systems have increased stability and there is less risk of falling compared to an exoskeleton system [22,23], this is at the cost of being less...
