In this study, a methodology has been developed with the objective of evaluating the surface roughness obtained during turning processes by measuring the signals detected by a force sensor under the same cutting conditions. In this way, the surface quality achieved along the process is correlated to several parameters of the cutting forces (thrust forces, feed forces and cutting forces), so the...

This study explored whether sensorimotor experiences of cutting down a tree in a virtual forest would be more effective compared to mentally simulating the same experience in terms of increasing pro-environmental self-efficacy and behavior in the physical, non-mediated world. Two modalities for embodying the tree-cutting experience were compared: immersive virtual environment and mental simulat...

MOTIVATION Hierarchical clustering is widely used to cluster genes into groups based on their expression similarity. This method first constructs a tree. Next this tree is partitioned into subtrees by cutting all edges at some level, thereby inducing a clustering. Unfortunately, the resulting clusters often do not exhibit significant functional coherence. RESULTS To improve the biological sig...

As was hinted at above, the fragmentation is encoded by a bintree. By this method, the fragmentation can be described in high resolution near sharp edges, and in low resolution at places where the exact shape of a fragment has a minor impact on the distortion (see Fig. 2). To find the optimal bintree, we start with a maximum tree, and prune this tree by cutting off all branches where the margin...

The traditional question of optimally deciding when to cut down a tree is among the most commonly posed questions asked of students learning the technique of dynamic programming. This paper shows that the traditional tree-cutting example is improperly formulated when the question of replanting is addressed, derives the proper method of finding optimal harvest length, and applies this method to ...

Composites are more and more increasing their importance as one of the most interesting group of materials, because of their unique properties. Hole drilling operations are common in composite parts to facilitate fastener assembly. As composites are non-homogeneous this operation causes some damages like delamination and others that reduce bearing and fatigue strength of the composite part. A p...
