Research in the last 15 years has led to die-less incremental forming processes that are close to realization in an industrial setup. Whereas many studies have been carried out with the intention of investigating technical abilities and economic consequences, the ecological impact of incremental sheet forming (ISF) has not been studied so far. Using the concept of exergy analysis, two ISF techn...

In this study, the incremental forming of explosively welded low carbon steel-commercially pure titanium bilayer sheet has been experimentally and numerically investigated. For this purpose, at first a finite element based analysis was proposed to predict forming force and thickness distribution to form this material by such process, that showed good agreements with the experimental results. Th...

The aim of this paper is to analyze the effect process parameters on coefficient friction (COF) in single-point incremental forming process. This investigation may be useful for further FEM analyses where tool-workpiece contact must set appropriately obtain adequate results. was analyzed between a solid tungsten carbide ⌀8 hemispherical ended tool with radius 4 mm and grade 2 pure titanium shee...

Recently, exemplar-based sparse representation phone identification features (Spif ) have shown promising results on large vocabulary speech recognition tasks. However, one problem with exemplar-based techniques is that they are computationally expensive. In this paper, we present two methods to speed up the creation of Spif features. First, we explore a technique to quickly select a subset of ...

BACKGROUND Endogenous PIF, upon which embryo development is dependent, is secreted only by viable mammalian embryos, and absent in non-viable ones. Synthetic PIF (sPIF) administration promotes singly cultured embryos development and protects against their demise caused by embryo-toxic serum. To identify and characterize critical sPIF-embryo protein interactions novel biochemical and bio-analyti...
