Published: June 2020

Abstract
Although the textile industry is in worldwide recession, the field of technical textile articles is in a continuous development, proving that the manufacturers of these products are concerned about finding solutions and creating high performance articles. Considering the need to increase productivity and product quality while reducing the consumption of materials, in the last decades, processing technologies specific to textile industry had a quick dynamic, that has led to the development of new, very efficient technological methods and processes, characterized by an advanced degree of automation. The proposed technological solution was developed based on the correlational analysis of the technological parameters of the variable geometry subassemblies, targeting the following technological aspects: monitoring of the functional parameters during the technological process development and real-time warning of the occurring dysfunctions; display of functional parameters and controls on a HMI touch panel display; adjusting the settings of the parameters of each inverter according to the dynamic parameters of the ordered devices (couple, speed, acceleration-deceleration, brake moment, etc.); PLC circuit logic programming via a software program dedicated to the application.

Abstract
We present a new class of wearable textile antenna and analyse their performances through an electrical study. The developed prototypes have been realized by an embroidery process and are made of conductive twisted copper/polyester yarns on a cotton substrate. These antennas aim to transfer power and data thanks to the NFC technology, so the operating frequency is 13.56MHz and the maximal reading distance is around 10cm. The strong resistance of the yarn (4.20Ω/m) make us overlap three yarns to reach satisfactory electrical characteristics. Antennas are composed of a textile plan circular coil to which we add a usual capacitor. The study of coils electrical characteristics highlights a linear evolution of coil resistance and inductance in function of embroidery geometrical parameters. Also, these data show the feasibility of such antennas, especially through quality factor values reaching 45.

Published: June 2020

Abstract
The textile and clothing industries are facing new challenges. Smart Textiles are a huge topic with a high market potential, however there are only few approaches in teaching this interdisciplinary field. Moreover, individuals are expected to continuously adapt to the new requirements by following the concept of lifelong learning. We propose a new concept that will integrate a smart textiles kit. This application-oriented construction kit should help to extend the frontiers of knowledge, stimulate creativity, and give students the ability to solve real-world problems. As added benefit it will accelerate the understanding of innovation and interdisciplinary challenges. The blended learning concept aims to prepare students to think interdisciplinary, broadly, deeply, and last but not least critically. Students will be ready to contribute to the development of new products and face the challenges of structural change along their working life.

Published: June 2020

Abstract
The use of piezoelectric nanocomposite in detection and actuation applications for the development of electromechanical microsystems (MEMS) has become quite common over the last decade. In this paper, we present a flexible piezoelectric nanocomposite films, composed of lead zirconate titanate (PZT) nanoparticles, embedded in poly(vinylidene-difluoride hexafluoro propylene) (PVdF-HFP) matrix. Piezoelectric and ferroelectric properties evolution is proportional to the evolution of the crystalline β-phase. The evaluation of the interactions between PZT and PVdF- HFP, performed by Fourier transform infrared spectroscopy (FTIR), revealed a dramatic improvement in these characteristics over pure PVdF-HFP, and attributed to a better crystallinity of the PVdF-HFP matrix and uniform distribution of nanoparticles. These films nanocomposites were done by solvent casting method, with various concentrations of PZT. Results of these experiments indicate that the investigated thin films nanocomposites are appropriate for various applications in energy storage and energy harvesting application.

Published: June 2020

Abstract
The aim of this work is to evaluate the potential application of textile and polyurethane aqueous dispersion in insulation application in the form of a nonwoven polyurethane composite. Based on their properties, nonwoven are promising insulation solution for buildings. However, the major disadvantage is their flammability and their low mechanical property. The main purpose of this research is to improve physical, thermal and acoustical properties of these materials, by using a thin layer of polyurethane. According to the experimental results, it can be concluded that the PU layer enhanced the barrier properties of textile nonwoven. Moreover, it has a great effect on the sound absorption coefficient and thermal conductivity. The results of this study provide an effective solution for insulation application. Indeed, these alternative materials will contribute to the cost advantage as well as the green building initiative.

Published: June 2020

Abstract
Managing the performance of port container terminals is one of the major challenges in the supply chain management. In response to this challenge, we propose a new framework to assess managers in evaluating the global performance of operations in port container terminals. The new framework integrates the Data Envelopment Analysis (DEA) and Artificial Neural Network (ANN). The DEA is used to compute the efficient score of the system. In ANN, we use the improved grey wolf optimizer based on Levy’s flights to improve learning. In order to prove the efficiency of our model, we apply the framework in 2 ports container terminal: Tangier Med Port and Casablanca Port. The result is compared to standard algorithms and outperforms the cited algorithm in order to avoid local minima. The new trainer improved grey wolf optimizer is also evaluated using four known classification datasets and on three approximation functions datasets.

Authors: Tseghai G B , Malengier B , Mengistie D A , Fante K A , Van Langenhove L 
Published: June 2020

Abstract
The purpose of this research work was to develop a textile-based strain sensor. A conductive textile fabric was produced by the coating of knitted cotton fabric with in-situ polymerization of polypyrrole. The sensor consists of a conductive textile as an electrode, stainless steel yarn as interconnection, Arduino Nano as a controller, HC05 Bluetooth module, and a Lithium polymer battery as a power source. For the demonstration, the sensor was placed on the upper arm and bicep stretch was performed. It was observed that the contraction of the arm muscle causes a reduction in resistance of the electrode. Therefore, change in swelling was successfully detected from the increase and drop of resistance during contraction and relaxation of the muscle. This principle could be applied to determine the status of peripheral edema, where the increase in resistance in this work indicates edema is becoming severe.
Investigating the effect of air permeability and moisture on 2.5GHz textile microstrip patch antenna performance

Published: June 2020

Abstract
When discussing textile antenna and its comfortable use, the effect of air permeability and atmospheric moisture are eminent factors which have direct influence on textile antenna transmission characteristics and comfort of the wearer when used practically. The rate of airflow under certain air pressure passing through any surface is termed as air permeability of that surface and amount of moisture regained by a material when exposed to varying environmental humidity ranges compared to dry weight of that material is its moisture regain. Fleece and spacer fabrics were selected each having different air permeability and moisture regain values but both fabrics constitute polyethylene terephthalate - PET. Microstrip patch antennas that resonate at 2.45GHz were constructed utilizing both textile fabrics. Spacer fabric has high air permeability and low moisture regain compared to fleece fabric. Spacer fabric is a knitted 3-dimensional structured fabric whereas fleece is nonwoven in structure. FlecTron® is utilized as the conductive part of the microstrip patch antenna. Antenna made off spacer fabric showed better transmission characteristics and are least altered due to change in humidity compared to antenna made off fleece fabric. In this research, we conclude that the selected textile spacer fabric, with its high air permeability and low moisture regain, is the most favourable textile material in the construction of textile antennas.

Thermal resistance of double jersey fabric knitted by different yarn raw material
Authors: Kopitar D , Pavlovic Z , Skenderi Z , Vrljicak Z 
Published: June 2020

Abstract
The research was carried out on five double jersey knitted fabrics, knitted from cotton, Viscose®, Tencel®, Modal® and polyester ring spun yarns finesses of 20 tex. A circular double bed knitting machine gauge of E17 with the same production parameters was used for knitting all the fabrics. A change in all knitted fabric structure parameters was reflected through fabric mass per unit area, which ranged from 142 g m−2 to 165 g m−2. The minimum and maximum knitted fabric mass per unit area difference is up to 16 %. The lowest thermal resistance have polyester, while the largest have cotton knitted fabric. Thermal resistance of cotton fabric is higher for 36.7 % related to polyester knitted fabric. Considering basic knitted fabric parameters, knitting with same constructional parameters but different yarn raw materials doesn’t provide knitted fabric with same mass per unit area or thickness, i.e. thickness factor. It can be concluded that beside basic knitted fabric parameters, yarn raw material influence on thermal resistance.

Published: June 2020

Abstract
Today, it is increasingly demanding, more complex and harder to achieve certain properties of fabric which are prescribed by standards for a particular purpose, and it is even more difficult to achieve the sustainability of these properties during use. In this paper, the most relevant physical-mechanical properties of thermal protective woven fabrics, made from meta-aramide yarns, after subjection to textile care, are investigated. This research is related to the objectives of the scientific project MF-WCOMPROTECET, which is based on the development of innovative multifunctional woven fabrics and composites for thermal protective clothing that will overcome the properties of the previous fabrics in the application.
Optical method for the determination of the roughness profile of woven fabrics
Authors: Vassiliadis S , Matsouka D , Watel Q , Jaouani H 
Published: June 2020

Abstract
Surface properties are important characteristics of textile fabrics. Apart from the tactile characteristics of the fabric, these properties can affect aspects of the fabric behaviour both in use and during further production processes. Fabric tactile characteristics and friction properties are just two of the properties connected to surface roughness. Typically surface roughness is determined using the KES-F system. This research paper proposes an innovative optical method for the measurement of fabric surface roughness based on image processing of photos of fabric cross-sections obtained through the stereoscopic microscope. Thirty parametric cotton woven fabrics were tested both in the warp and weft direction and the surface roughness for each fabric was obtained as a percentage of the void areas on the surface of the fabric.
Microstructural characterization of different metal matrix composite claddings reinforced by TiC through YAG laser cladding
Authors: Mahmoud Essam R I , Tirth Vineet , Algahtani Ali , Khan Sohaib Z 
Published: June 2020

Abstract
In this work, a YAG laser was used to clad TiC-reinforced metal matrix composite layers on the surface of different types of metals; low carbon steel, high C–Cr bearing tool steel, spheroidal graphite cast iron and commercially pure titanium. The cladding processes were carried out at heat inputs ranging from 175 J mm−1 to 700 J mm−1 and at a fixed traveling speed of 4 mm s−1. The microstructures of the cladding layers were investigated in detail. In all cases, TiC-surface metal matrix composite layers were successfully formed at different laser heat inputs on all the metal surfaces. A few TiC particles seemed as fine dendrites after the laser treatment. The amount of dendritic TiC has a direct relationship with the laser heat input. For low carbon steel, the clad layer showed a martensitic structure, with sound metallurgical bonding to the base metal and without any defects at the highest laser heat input used in this study (700 J mm−1). In the case of high C–Cr bearing tool steel, lower laser heat inputs were enough to form a sound clad layer consisting of fine TiC dendrites distributed in a matrix of martensite laths, some retained austenite and acicular carbides. Laser heat input of 175 J mm−1 was enough to build a defect-free clad layer on spheroidal graphite cast iron. The matrix comprised of cementite, martensite, and some blocks of retained austenite. Cracking appears at a higher heat input of 500 J mm−1 in the spheroidal graphite cast iron. The matrix of the clad layer on pure Ti substrate was α′-Ti martensite, which decreased by increasing the laser heat input.

Abstract
In the current study, XRD analysis shows the polycrystalline form an inverse spinel Fe3O4 structure. Fe3O4 film is prepared by dip coating method on MEMS gas sensors to test the sensitivity on volatile organic compound (VOC) gas. VOC is being tested at 92 mW (∼300 °C) power consumption with different VOC gas concentrations and also tested with different gases like NO2, SO2, NH3 and CO gas. The results showed that the Fe3O4 gas sensor has better selectivity and high response with VOC 1.2 ppm concentration. Structural morphology is seen and reaction mechanism when VOC gas reacts with Fe3O4 material is also being discussed.
Noisy distributed sensing in the Bayesian regime
Authors: Wölk S , Sekatski P , Dür W 
Published: June 2020

Abstract
We consider non-local sensing of scalar signals with specific spatial dependence in the Bayesian regime. We design schemes that allow one to achieve optimal scaling and are immune to noise sources with a different spatial dependence than the signal. This is achieved by using a sensor array of spatially separated sensors and constructing a multi-dimensional decoherence free subspace. While in the Fisher regime with sharp prior and multiple measurements only the spectral range Δ is important, in single-shot sensing with broad prior the number of available energy levels L is crucial. We study the influence of L and Δ also in intermediate scenarios, and show that these quantities can be optimized separately in our setting. This provides us with a flexible scheme that can be adapted to different situations, and is by construction insensitive to given noise sources.

were produced during the process of combustion of the glycine-nitrate with precursors together with an excess amount of the oxidizing agent. X-ray diffraction patterns and Raman spectra were measured for investigation of the structure of the synthesized material. Hidden periodicities were extracted in the Raman spectra, using the example of two compounds with x = 0 and x = 0.2, correspondingly. In comparison with theory, the analysis showed that the distribution of the inverse periods revealed from the experiment results in the appearance of two narrow peaks common for both samples with maximums 0.014 and 0.01 cm (70 and 100 cm−1). The discovered effect is analyzed with the model of a combination of Raman- active oscillations from the nanoscale inelastic light scatterers with different shapes.
Diagnosis and Treatment of Patients With Acute Myeloid Leukemia With Myelodysplasia-Related Changes (AML-MRC)
Authors: Arber Daniel A , Erba Harry P 
Published: June 2020

Abstract

Objectives
Acute myeloid leukemia (AML) with myelodysplasia-related changes (AML-MRC) represents a high-risk and somewhat diverse subtype of AML, and substantial confusion exists about the pathologic evaluation needed for diagnosis, which can include the patient’s clinical history, cytogenetic analysis, mutational analysis, and/or morphologic evaluation. Treatment decisions based on incomplete or untimely pathology reports may result in the suboptimal treatment of patients with AML-MRC.

Methods
Using a PubMed search, diagnosis of and treatment options for AML-MRC were investigated.

Results
This article reviews the current diagnostic criteria for AML-MRC, provides guidance on assessments necessary for an AML-MRC diagnosis, summarizes clinical and prognostic features of AML-MRC, and discusses potential therapies for patients with AML-MRC. In addition to conventional chemotherapy, treatment options include CPX-351, a liposomal encapsulation of daunorubicin/cytarabine approved for treatment of adults with AML-MRC; targeted agents for patients with certain mutations/disease characteristics; and lower-intensity therapies for less fit patients.

Conclusions
Given the evolving and complex treatment landscape and the high-risk nature of the AML-MRC population, a clear understanding of the pathology information necessary for AML-MRC diagnosis has become increasingly important to help guide treatment decisions and thereby improve patient outcomes.
