Published: January 2019

Abstract
In this article, a computerized method is proposed for simulating digital woven fabric (DWF) based on sequential yarn images captured from a moving yarn. A mathematical model of woven fabric structure is established by assuming that the crimped shape of yarns in weave structure is elastica, and the cross-sections of yarn in sequence image and fabric are circular and ellipse, respectively. The sequential yarn images, which are preprocessed and stitched first by image processing methods, are resized based on the mathematical model. Then a light intensity curve, which consists of radial curve model and axial curve model, is used to simulate the gray texture distribution of interlacing points in radial and axial directions. Finally, a Boole Matrix model is used to control the woven pattern. In the experiment, a slub yarn and a normal yarn samples with same count are applied to simulate gray texture fabrics. Then the gray fabrics are transformed to color fabrics based on three color maps. The fabric simulations are confined to single fabrics of plain, 2/2 matt, and 1/3 twill weaves.

Published: January 2019

Abstract
Thermal protective clothings are produced from multilayered textile materials. Fabric layers need to allow enough evaporation of perspiration, ventilation, and also thermal protection from fire. This study aimed to evaluate the effects of different fabric layers and their different combinations on the thermal properties of multilayered fabric samples. Three-layered fabric combinations were created using two types of outer shell fabrics, four types of moisture barrier fabrics with membrane, and two types of thermal barrier fabrics. Sixteen different fabric combinations that simulate three-layered thermal protective clothing were studied. As a result of the study, it was found that thermal and moisture comfort properties were significantly affected by different fabric layers.
Numerical Simulation of Flow Field in Air-Jet Loom Main Nozzle
Authors: He Shanshan , Qian Yi , Xue Wenliang , Cheng Longdi 
Published: January 2019

Abstract
To improve airflow injection capacity of the main nozzle and decrease backflow phenomenon, a new main nozzle structure with two throats is designed. Negative pressure value and negative pressure zone length are first proposed evaluating the strength of backflow phenomenon. Commercial computational fluid dynamic (CFD) code “Fluent” is performed to simulate the flow field inside and outside the main nozzle. Exit velocity increases about 10 m/s in new main nozzle. Airflow core length of the new main nozzle is 35% higher than that of commonly used main nozzle. Smaller negative pressure value and shorter negative pressure zone length mean a weaker backflow phenomenon in the new main nozzle. Bigger air drag force indicates stronger weft insertion ability in the new main nozzle.

Published: January 2019

Abstract
This study analyses China’s One Belt, One Road (OBOR) initiative for the Baltic and South Caucasus countries. Trade, Foreign Direct Investments and transit potential are taken as main factors for the cooperation. A clash of China and the West in pursuing economic leadership is taken into account. The study suggests a new, alternative route for the OBOR initiative through the Caucasus, which has all the needed infrastructure and readiness for being started. Moreover, Georgia is not new to the EU preferences, it has experience of GSP+ and now the unique achievement of free trade regimes with the EU and China is also taken as an alternative route and an advantage for the Caucasus and the Baltic States.
Characterization and engineering of photoactivated adenylyl cyclases

Published: January 2019

Abstract
Cyclic nucleoside monophosphates (cNMP) serve as universal second messengers in signal transduction across prokaryotes and eukaryotes. As signaling often relies on transiently formed microdomains of elevated second messenger concentration, means to precisely perturb the spatiotemporal dynamics of cNMPs are uniquely poised for the interrogation of the underlying physiological processes. Optogenetics appears particularly suited as it affords light-dependent, accurate control in time and space of diverse cellular processes. Several sensory photoreceptors function as photoactivated adenylyl cyclases (PAC) and hence serve as light-regulated actuators for the control of intracellular levels of 3′, 5′-cyclic adenosine monophosphate. To characterize PACs and to refine their properties, we devised a test bed for the facile analysis of these photoreceptors. Cyclase activity is monitored in bacterial cells via expression of a fluorescent reporter, and programmable illumination allows the rapid exploration of multiple lighting regimes. We thus probed two PACs responding to blue and red light, respectively, and observed significant dark activity for both. We next engineered derivatives of the red-light-sensitive PAC with altered responses to light, with one variant, denoted DdPAC, showing enhanced response to light. These PAC variants stand to enrich the optogenetic toolkit and thus facilitate the detailed analysis of cNMP metabolism and signaling.
A review of data-driven fault detection and diagnosis methods: applications in chemical process systems
Authors: Md Nor Norazwan , Che Hassan Che Rosmani , Hussain Mohd Azlan 
Published: January 2019

AbstractFault detection and diagnosis (FDD) systems are developed to characterize normal variations and detect abnormal changes in a process plant. It is always important for early detection and diagnosis, especially in chemical process systems to prevent process disruptions, shutdowns, or even process failures. However, there have been only limited reviews of data-driven FDD methods published in the literature. Therefore, the aim of this review is to provide the state-of-the-art reference for chemical engineers and to promote the application of data-driven FDD methods in chemical process systems. In general, there are two different groups of data-driven FDD methods: the multivariate statistical analysis and the machine learning approaches, which are widely accepted and applied in various industrial processes, including chemicals, pharmaceuticals, and polymers. Many different multivariate statistical analysis methods have been proposed in the literature, such as principal component analysis, partial least squares, independent component analysis, and Fisher discriminant analysis, while the machine learning approaches include artificial neural networks, neuro-fuzzy methods, support vector machine, Gaussian mixture model, K-nearest neighbor, and Bayesian network. In the first part, this review intends to provide a comprehensive literature review on applications of data-driven methods in FDD systems for chemical process systems. In addition, the hybrid FDD frameworks have also been reviewed by discussing the distinct advantages and various constraints, with some applications as examples. However, the choice for the data-driven FDD methods is not a straightforward issue. Thus, in the second part, this paper provides a guideline for selecting the best possible data-driven method for FDD systems based on their faults. Finally, future directions of data-driven FDD methods are summarized with the intent to expand the use for the process monitoring community.
VAAs Users’ Voting Behavior and the Role of Partisanship. Evidence from the 2014 Belgian Federal Elections
Authors: Gallina Marta 
Published: January 2019

Abstract
In this article, I investigate the effects of Voting Advice Applications (VAAs) on voting behavior of their users. It has been already demonstrated that voters are more likely to follow VAAs recommendation when this latter is consistent with their previous vote intentions. However, the role of partisan attachments in this process has been generally overlooked. The basic idea that I intend to test, indeed, is that partisanship works as strong attitude in voters’ minds, making their preferences less amenable to VAAs advices if compared to those of non-partisan citizens. By implementing logistic regression models on panel data from the 2014 Belgian Federal elections, I show that it is actually unlikely that citizens decide to switch their vote after having played the test, if the advice is not consistent with pre-existing vote intentions. More importantly, I find that the impact of VAAs advice on vote choice is even weaker among citizens that declare to feel attached to a party.

Published: January 2019

Abstract
The phosphor SrMoO4:Pr3+ was successfully prepared by high-temperature solid-state reaction process, and characterised by X-ray diffraction (XRD), scanning electron microscope (SEM), and fluorescence spectrometer. The results show that the prepared SrMoO4:Pr3+ has a scheelite structure with pure phase and represents leaf-like shapes with good dispersity. The strong electron absorbabilities are located at 220–300 nm (charge transfer band), 448, 474, and 487 nm, respectively. The emission spectrum of the SrMoO4:Pr3+ phosphor was characterised, which peaked at 529, 545, 554, 600, 619, and 645 nm, corresponding to the f–f transitions of Pr3+. The average International Commission on Illumination (CIE) chromaticity coordinates of the phosphors are x≈0.455, and y≈0.520, and the optimum doping mole fraction of Pr3+ is 0.2 mol.%. To better understand the fluorescent behavior of as-prepared phosphors, a complete 91×91 energy matrix was built by an effective Hamiltonian operator, including free ion and crystal-field interactions. The fluorescent spectra of Pr3+ ion at the tetragonal (S
4) Sr2+ site of SrMoO4 crystal were firstly calculated from a full diagonalisation (of energy matrix) method. The fitting values are in good agreement with the experimental data.
Jeans Instability of Rotating Viscoelastic Fluid in the Presence of Magnetic Field
Authors: Sharma Praveen Kumar , Argal Shraddha , Tiwari Anita , Prajapati Ram Prasad 
Published: January 2019

Abstract
The Jeans instability of rotating viscoelastic fluid in the presence of uniform magnetic field is investigated using the generalised hydrodynamic (GH) model. A general dispersion relation is derived with the help of linearised perturbation equations using the normal mode analysis, which is further discussed for axis of rotation parallel and perpendicular to the direction of the magnetic field in both the weakly coupled (hydrodynamic) and strongly coupled (kinetic) limits. The onset criterion of Jeans instability for magnetised rotating viscoelastic fluid is obtained, which remains unaffected by the presence of rotation and magnetic field but depends upon viscoelastic effects. The graphical illustrations are depicted to see the influence of rotation, Mach number, shear and viscous effects, and sound speed on the growth rate of Jeans instability. It is found that all these parameters have stabilising influence on the growth rate of Jeans instability; hence, they are capable of collapsing to a self-gravitating, rotating, magnetised viscoelastic medium.
Zinc-lead ordering in equiatomic rare earth plumbides REZnPb (RE=La–Nd and Sm–Tb)
Authors: Heletta Lukas , Pöttgen Rainer 
Published: January 2019

Abstract
The plumbides REZnPb (RE=rare earth metals La–Nd and Sm–Tb) were synthesized by induction melting of the elements in sealed niobium ampoules. The samples were characterized by X-ray powder diffraction. The structures of the praseodymium and neodymium compound were refined from single-crystal X-ray diffractometer data: YPtAs type, P63/mmc, a=461.32(8), c=1658.00(3) pm, wR2=0.0588, 267 F
2 values, 12 variables for PrZnPb and a=460.12(3), c=1642.7(1), wR2=0.0617, 243 F
2 values, 12 variables for NdZnPb. The plumbides with RE=La, Ce, Sm, Gd and Tb are isotypic while the Zintl phase EuZnPb crystallizes with the orthorhombic TiNiSi type, Pnma, a=796.6(2), b=482.53(9), c=822.9(2) pm. The zinc and lead atoms build up polyanionic networks: slightly puckered Zn3Pb3 layers in AA′BB′ stacking sequence in the YPtAs type plumbides and a three-dimensional [ZnPb]2− network with distorted tetrahedral ZnPb4/4 coordination in EuZnSn. The different crystal structures are a consequence of the valence electron count, i.e. 18 for EuZnSn and 19 for the hexagonal plumbides. The crystal chemical details and bonding peculiarities are discussed.

Published: January 2019

Abstract
Nickel–zinc ferrites are soft magnetic materials that have different technological applications due to their low magnetic coercivity, high electrical resistivity and low eddy current loss. The soft ferrites are the best for manufacturing core of power transformers, recording heads, data storage devices, telecommunication equipment, media devices, microwaves and electronic devices. In current investigation, a series of zinc doped nickel ferrites (ZnxNi1−xFe2O4, x = 0.1, 0.2, 0.3, 0.4 and 0.5) were prepared by hydrothermal method (at 220 °C, 16 h). The structural, magnetic and dielectric properties were measured. X-ray diffractometer and fourier transform infrared spectroscopy (FTIR) were used to analyze the structural properties and structure of zinc doped nickel ferrites was spinel. As the concentration of Zn was increased, the structural properties (lattice constant, density, dislocation density, radii of tetra and octahedral sites and oxygen positional parameters) were also changed. FTIR results showed the strongest absorption band at 500–600 cm−1, which indicate the intrinsic stretching vibration of Zn+2 ↔ O bond (Mtetra ↔ O) at tetrahedral site. Vibrating sample magnetometer (VSM) was used to measure magnetic properties and it was observed that the value of saturation magnetization increased with Zn concentration. The investigation of frequency dependent dielectric property was measured by Impedance Analyzer. Dielectric constant and tangent loss decreased at higher frequency, whereas AC conductivity increased with frequency.
