The present work aims at comparing the performance of several quadratic programming (QP) solvers for simulating large-scale frictional rigid-body systems. Traditional time-stepping schemes for simulation of multibody systems are formulated as linear complementarity problems (LCPs) with copositive matrices. Such LCPs are generally solved by means of Lemketype algorithms and solvers such as the P...

Incorporation of liquid crystalline polymers (LCPs) into commodity polymers remains a challenge in the design of high-performance, low-cost polymeric blends. Blends of a thermoplastic polymer and a nematic LCP are produced here by mechanical alloying. Functionality sensitive X-ray microscopy reveals LCP dispersions as small as 100 nm in diameter. Intimate mixing remains upon subsequent melt pro...

To investigate the role of DNA methylation during human development, we developed Methyl-seq, a method that assays DNA methylation at more than 90,000 regions throughout the genome. Performing Methyl-seq on human embryonic stem cells (hESCs), their derivatives, and human tissues allowed us to identify several trends during hESC and in vivo liver differentiation. First, differentiation results i...

OBJECTIVES To evaluate the reproducibility of catheter-based intracoronary near-infrared spectroscopy (NIRS) for the detection of lipid core coronary plaques (LCPs) and to examine stenting-induced changes in NIRS findings. BACKGROUND The in-vivo reproducibility of coronary NIRS findings and their changes after stenting have not previously been characterized. METHODS NIRS assessment using an...

In recent years, resource-rich developing countries have increasingly adopted Local Content Policies (LCPs) as a means of stimulating locally-driven, resource-based development. Such policies, which seek to catalyse development through the procurement local goods and services in regions where mining oil gas production takes place, are now prevalent some 49 around world. Yet, many cases they bee...

Based on the recent analysis of various databases, cold spray (CS), newest method among thermal spraying technologies, has received unabated attention hundreds researchers continuously since its invention in 1980s. The significance CS lies low process temperature, which usually ensures compressive residual stresses and allows for formation coatings a thermally sensitive substrate. This paper co...

Liquid-crystal polymers (LCPs) are well known materials for functional sensor and actuators, because of their high-responsiveness to an electric field. Owing to their complex physical nature, however, the prediction of the functions of LCPs is a challenge. To attack this problem from a molecular point of view, a simulation study is a promising approach. In this work, for future applications of ...

Three-dimensional flows of liquid crystalline polymers (LCPs) in a rectangular 3 to 1 abrupt contraction channel and a rectangular 1 to 3 abrupt expansion channel are numerically analyzed to investigate the molecular orientation behavior of LCPs in complex flows. A modified Doi model is used as a constitutive equation and MAC (marker and cell)-based finite difference method is employed for the ...

We study the microstructure formation and defects dynamics arising in liquid crystalline polymers (LCPs) in plane shear flow by a inetic–hydrodynamic coupled model. The kinetic model is an extension of the Doi theory with a non-local intermolecular potential, including ranslational diffusion and density variation. LCP molecules are ensured anchoring at the boundary by an additional boundary pot...

Abstract. Installing targets and measuring them as ground control points (GCPs) are time consuming cost inefficient tasks in a UAV photogrammetry project. This research aims to automatically extract GCPs from 3D LiDAR mobile mapping system (L-MMS) measurements imagery perform aerial triangulation photogrammetric network. The L-MMS allows acquire point clouds of an urban environment including fl...
