Sensory Evaluation in Characterization of Fabric Hand

This paper is divided in two parts. The first part presents optimized methods for formalizing and analyzing sensory data provided by different panels on fabric hand evaluation. For achieving this challenge, we first transform each evaluation into fuzzy sets and we submit criteria for assessing the fabric hand evaluation given by experts as well as criteria for computing the distances between different panels and the employed linguistic terms in different evaluation spaces. This sensory data analysis allows us to check expert’s and customer’s behaviors on fabric hand. Based on this first procedure about formalization and sensory data analysis, we can study the relationships between sensory evaluation given by different experts for a fabric set and the objective data set provided by appropriate measurements. From a set of fabric samples, a database with nearly 10 parameters characterizing the touch handle is built. This way of evaluation is performed by measuring a set of physical parameters on fabrics. Those parameters constitute the input variables of our model. For the textile industry, the major difficulty lies in the fact that the performed measurements on fabrics lead to precise numerical data describing indirectly fabric hand but their relationships with the evaluation given by experts should be exploited. We implement a fuzzy model which predicts the marks reached for a set of linguistic terms. The effectiveness of these methods and criteria is shown through a number of knitted cotton fabrics.

China Textile 2015年第5期 31-35页

作者： Salma Abaoubida Mohamed Mouhib Annika Hanel Sarah Kim Zhao Zihan Engineering School ENSAIT Textile and Design Reutlingen University

The co-location Spring Shows, including Intertextile Shanghai Apparel Fabrics - Spring Edition, Yarn Expo Spring, PH Value and China International Fashion Fair （CHIC）, shined in Shanghai this March, bringing apparel fabrics, yarns and fibers, knitwear and other fashion garments under one roof. Taking this good opportunity, Xiao Lan, Teacher of College of Textiles, Donghua Universily, organized the overseas students to altend the show and asked them to write visit reports. Though the same show they visited, different perspectives and focuses were expressed through reports. The editor of China Textile selected four of them as a representative to share with the readers.

An Enhanced Privacy Preserving, Secure and Efficient Authentication Protocol for VANET

引用

Computers, Materials & Continua 2022年第5期71卷 3703-3719页

作者： Safiullah Khan Ali Raza Seong Oun Hwang Department of IT Convergence Engineering Gachon UniversitySeongnam13320Korea ensait GEMTEX-Laboratoire de Genie et Materiaux TextilesUniversity of LilleLilleF59000France School of Computing&Institute of Cyber Security(ICSS) University of KentUnited Kingdom Department of Computer Engineering Gachon UniversitySeongnam13320Korea

Vehicular ad hoc networks (VANETs) have attracted growing interest in both academia and industry because they can provide a viable solutionthat improves road safety and comfort for travelers on roads. However, wireless communications over open-access environments face many security andprivacy issues that may affect deployment of large-scale VANETs. Researchershave proposed different protocols to address security and privacy issues in aVANET, and in this study we cryptanalyze some of the privacy preservingprotocols to show that all existing protocols are vulnerable to the Sybilattack. The Sybil attack can be used by malicious actors to create fakeidentities that impair existing protocols, which allows them to imitate trafficcongestion or at worse cause an accident that may result in the loss of humanlife. This vulnerability exists because those protocols store vehicle identitiesin an encrypted form, and it is not possible to search over the encryptedidentities to find fake vehicles. This attack is serious in nature and veryprevalent for privacy-preserving protocols. To cope with this kind of attack,we propose a novel and practical protocol that uses Public key encryptionwith an equality test (PKEET) to search over the encrypted identities withoutleaking any information, and eventually eliminate the Sybil attack. Theproposed approach improves security and at the same time maintains privacyin VANET. Our performance analysis indicates that the proposed protocoloutperforms state-of-the-art protocols: The proposed beacon generation timeis constant compared to a linear increase in existing protocols, with beaconverification shown to be faster by 7.908%. Our communicational analysisshows that the proposed protocol with a beacon size of 322 bytes has the leastcommunicational overhead compared to other state-of-the-art protocols.

Polyester(PET) was pre-activated by atmospheric air plasma and coated by various inorganic oxide nanoparticles(MOx) such as titanium dioxide(TiO2), zinc oxide(ZnO), and silicon oxide(SiO2), using poly(vinylidene fluoride)(PVDF) and chitosan(CT) as binders. The resulting PET-PVDF-MOx-CT composites were thermally compressed and then characterized by scanning electron microscopy, Fourier infrared spectroscopy, thermal gravimetric analysis, and flame retardancy(FR) ability tests. PET modifications resulted in more thermally stable and less harmful composites with weaker hazardous gas release. This was explained in terms of structure compaction that blocks pyrolysis gas *** incorporation was found to reduce the material susceptibility to oxidation. This judicious procedure also allowed improving flame retardancy ability, by lengthening the combustion delay and slowing the flame propagation. Chitosan also turned out to contribute to a possible synergy with the other polymers present in the synthesized materials. These results provide valuable data that allow understanding the FR phenomena and envisaging low-cost high FR materials from biodegradable raw materials.

We want to conclude on the interest of the “crimping” process used to produce the glass wool and to make a comparison for anisotropic factor obtained from structural property (air permeability) as well as thermal property (thermal conductivity and diffusivity). The main structural (densities, porosity, specific surface, air permeability) and the thermal (conductivity, diffusivity, heat capacity) characteristics of this glass wool are presented. Thermal results are determined by using several methods (Hot disc (HD), Heat Flow Meter (HFM) and Guarded Hot Plate).

This paper presents a web-based integrated system for on-line sensory fabric hand evaluation. The methods of fuzzy techniques, neural networks, classical factorial analysis and other data analysis are used in the system to analyze the objective and subjective data, and to build the relationship between them. Given the objective data of a new fabric sample, the system can provide its sensory hand data and its total hand grade. In meantime, the total hand grade can be obtained directly from the sensory fabric hand data if provided. The sensory evaluation system is developed in Internet environment using Java language and SQL server database management system.
