Infusion medical devices (MDs) used in hospitals are often made of plasticized polyvinylchloride (PVC). These plasticizers may leach out into infused solutions during clinical practice, especially during risk-situations, e.g multiple infusions in Intensive Care Units and thus may enter into contact with the patients. The migrability of the plasticizers is dependent of several clinical parameter...

This paper presents an application of the Waveform inversion approach to localization of objects in reverberant fields and with limited spatial measurements. Reverberant fields in enclosures can potentially carry useful information, however, in an incoherent way. Incoherency comes from the consecutive reflections of the wave energy several times in the domain. This, along with diffraction and d...

Using floating-point arithmetic to solve a numerical problem yields a computed result, which is an approximation of the exact solution because of roundoff errors. In this paper, we present an approach to certify the computed solution. Here, ”certify” means computing a guaranteed enclosure of the error between the computed, approximate, result and the exact, unknown result. We discuss an iterati...

We study a recently introduced generalization of the Vertex Cover (VC) problem, called Power Vertex Cover (PVC). In this problem, each edge of the input graph is supplied with a positive integer demand. A solution is an assignment of (power) values to the vertices, so that for each edge one of its endpoints has value as high as the demand, and the total sum of power values assigned is minimized...

Objectives: The Percentage of vowel correct (PVC) is one of the indices in the development of articulation and phonological skills in children that can be measured with speech samples that could be extracted from the single word or connected speech tests. The aim of this study is to introduce the PVC scale in Persian speaking children and investigate its validity and reliability. Methods: Th...

In the field of unmanned systems, cameras and LiDAR are important sensors that provide complementary information. However, question how to effectively fuse data from two different modalities has always been a great challenge. this paper, inspired by idea deep fusion, we propose one-stage end-to-end network named FusionPillars multisensor (namely point cloud camera images). It includes three bra...

PVC/NiFe2O4/Fe2O3 compositewas successfully synthesized and characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), and scanning electron microscopy (SEM). Also, the catalytic activity of PVC/NiFe2O4/Fe2O3 has been considered in the synthesis of two arylidene barbitu...

A numerical investigation was carried out in order to predict the effects of symmetric heating on irregular acoustic streaming in air-filled shallow enclosures. The fluid motion is driven by periodic vibration of the enclosure left wall. The vertical walls of the enclosure are adiabatic while the horizontal walls are heated symmetrically. A control-volume method based, explicit time-marching Fl...

The influence of maleation on thermal and dynamic-mechanical properties of wood-PVC composites was investigated in this study. Experimental results indicated that maleation had a significant influence on most of the properties for wood-PVC composites. Storage modulus (E’), loss modulus (E”), and complex modulus (E*) of resultant wood-PVC composites were related to the retention levels and graft...
