In this paper, we present newly explored families of rigid-foldable cylinders and the cellular structures constructed from these cylinders; the families include zonogon extrusion cells, bi-directionally flat-foldable cells, and a novel type of cells, i.e., woven cylinder cells. We show the geometry of such structures to demonstrate their validity, their parametric design method, and their kinet...

The percentage of encrypted network traffic increases steadily not only by virtual private networks of companies but also by protocols like SSH or SSL in the private sector. Traditional Intrusion Detection Systems (IDS) are not able to cope with encrypted traffic. There are a few systems which are able to handle encrypted lines but none of them is applicable in general because of the necessity ...

A multidisciplinary approach to develop the future implant site in the aesthetic zone was illustrated. A patient with perio-endo combined lesion at her upper central incisors was treated. Before extraction, forced eruption was performed and 12 months later, satisfactory amount of bone apposition was detected. At 2 weeks after atraumatic extraction, implants were placed and loaded with implant-s...

In this paper, a method called 2-stage extrusion is proposed to reconstruct a solid by modifying the incremental extrusion [Shum SSP. Solid reconstruction from orthographic opaque views using incremental extrusion. Computers & Graphics 1997;21(6):787±800; Shum SSP et al. A low-cost wireframe-to-solid implementation for reverse engineering. AUTOFACT'97 Conference, 3±6 November 1997, MS98(159), 1...

Homeostatic maintenance of epithelial tissues requires the continual removal of damaged cells without disrupting barrier function. Our studies have found that dying cells send signals to their live neighbors to form and contract a ring of actin and myosin that ejects it out from the epithelial sheet while closing any gaps that might have resulted from its exit, a process termed cell extrusion¹....

In this contribution the influence of an extrusion process on the viscosity function of rubber blends is identified. This knowledge is required for performance of realistic numerical simulations of injection heads and extrusion tools for rubber profile production. The experimental basis of this investigation are tests with both, capillary and extrusion rheometer. The latter is a combination of ...

INTRODUCTION To assess the amount of debris extruded apically during instrumentation of distal canals of extracted primary molars by three instrument systems [ProTaper Universal (PTU), ProTaper NEXT (PTN), and self-adjusting file (SAF)] compared with conventional stainless steel hand K-files (HF, control). MATERIALS AND METHODS Primary mandibular molars (n = 120) with a single distal canal we...

To evaluate the effects of extrusion process on the trans fatty acids (TFAs) formation in soybean crude oils, three different extrusion parameters, namely, extrusion temperature (80-160 °C), feed moisture (10-26%), and screw speed (100-500 rpm), were carried out. It was found that only five different types of TFAs were detected out using gas chromatography-mass spectrometry. Before the extrusio...

Back-propagation (BP) neural network is used to develop process models for the parison extrusion in extrusion blow molding based on experimental data. In applying the BP network, some modifications, such as using a self-adaptive learning rate coefficient, determining the number of hidden neurons through experimentation, and so on, to the original BP algorithm are carried out to speed up learnin...

Room temperature direct-ink-write printing of epoxy-nanoclay-carbon fiber composites produces parts with high stiffness and strength. Establishing clear relationships between print parameters, filler orientation, properties is difficult, in part owing to challenges characterization. Here, we perform scanning microbeam X-ray scattering 5 micrometer spatial resolution on cross-sections printed (a...
