In modern agriculture, one of the most influential and debatable problems are related to the water management and soil pollution. The water management issue is obviously connected to the usage of the lowest quantity possible, due to the scarce nature of ...

We introduce a technique for furbricating 3D printed hair, fibers and bristles, by exploiting the stringing phenomena inherent in 3D printers using fused deposition modeling. Our approach offers a range of design parameters for controlling the ...

With the rapid growth of waste electrical and electronic equipment (WEEE) and hindrance to the distribution of recycled polymers due to the presence of polybrominated diphenyl ethers (PBDEs), plastics from WEEE have been an important environmental ...

MARSUI is a hardware deformable prototype exhibiting plastic (shape-retaining) behavior. It can track the shape that the user creates when deforming it. We envision that a set of predefined shapes could be mapped onto particular applications and ...

Presented in this paper is a new stress-strain relation for stainless steel alloys that provides the stress as an explicit function of the strain. The relation is an approximate inversion of a recently proposed three-stage stress-strain relation based on ...

This paper aims at seeking a practical method for simulating the rigidity test of automotive steel wheel. This test of automotive wheel is numerically analyzed by combined use of nonlinear finite element analysis and plastic mechanics approach. The ...

Transition theory has been used to derive the elastic-plastic and transitional stresses. Results obtained have been discussed numerically and depicted graphically. It has been observed that for disc with exponentially varying thickness (k=2), high ...

Ubiquitous computing research has recently focused on 'busyness' in American households. While these projects have generated important insights into coordination and communication, we think they overlook the more spontaneous and opportunistic activities ...

In this paper we describe a numerical algorithm for the study of shear-band formation and growth in a two-dimensional antiplane shear of granular materials. The algorithm combines front-tracking techniques and adaptive mesh refinement. Tracking provides a ...
