Abstract:

Qualité et flexibilité sont les deux atouts de l'industrie textile des pays industrialisés pour faire face à la concurrence. Pour jouer son rôle de référence, le contrôle qualité doit être automatisé. Insuffisantes, les machines actuelles doivent être améliorées tant au niveau des méthodes que des matériels: c'est ce qui a été fait dans le cadre d'un programme BRITE. Les travaux ont porté sur les méthodes et particulièrement sur l'extraction des défauts de leur contexte texture. La méthode proposée s'appuie sur un principe connu, la transformée de Fourier et débouche sur un filtrage nouveau pe

Centrée sur l'espace constitué par le royaume de France et ses colonies, cette thèse met en évidence les structures et les dynamiques du marché de l'indigo, entre le milieu du XVIIe et la fin du XVIIIe siècle.

Le secteur de la finition des étoffes est alors un secteur fondamental de la production textile. Il est réglementé afin de garantir aux consommateurs la solidité et la beauté des couleurs, mais au cours du XVIIIe siècle, devient

Abstract:

The tendency to wear out and change is inherent in most materials, but – aside from a few exceptions – has been considered to be undesirable by both the industry and consumers. The work presented in this licentiate thesis suggests that, due to change in some form being an inherent property of textiles, it may be viable to look for alternative ways of designing and perceiving textiles that accept change as one of their qualities. The experimental work explores change as a quality in textiles from the perspective of the textile material, and examines irreversible changes in textiles from three

Abstract:

[Abstract]: The textile industry has a recurrent white speck nep problem in cotton. “White specks” are immature clusters of fibres that are not visible as defects until dyeing, after which they remain white on the surface of a darkly dyed fabric, or appear as non uniform streaks in the fabric. Both results render the fabric unsuitable for commercial fashion fabrics. The white speck potential of cotton is difficult to predict except in extremely immature cottons. Competitive synthetic fibres are uniform in length and strength and never have a maturity problem resulting in dye defects. They are

To meet both constraints, rendering uses texture mapping which maps 2D textures onto scene objects. Over time, the count an

Abstract:

Malfunctions on loom machines are the main causes of faulty fabric production. An on-loom fabric inspection system is a real-time monitoring device that enables immediate defect detection for human intervention. This dissertation presented a solution for the on-loom fabric defect inspection, including the new hardware design—the configurable contact image sensor (CIS) module—for on-loom fabric scanning and the defect detection algorithms. The main contributions of this work include (1) creating a configurable CIS module adaptable to a loom width, which brings CIS unique features, such as sub-m

Abstract:

Thesis (MTech (Business Administration))--Cape Peninsula University of Technology, 2007<br>An assessment undertaken by the Clothing and Textile Centre in the Western Cape (Clotex) during 2002 revealed that there was a great need for quality in the clothing sector. Furthermore, the research undertaken by the Department of Science and Technology (2004) supports and recommends the development of simple, paper-based systems for implementation and measurement for quality and production systems. An analysis of the macro- and micro-environmental factors confronting the clothing industry reve

Full text

Abstract:

The carbon in metallurgical coke is composed of textural units, varying in size and shape depending on the rank of coal carbonized. These induce a characteristic texture to coke surfaces. This thesis describes a study of the bearing of this texture on coke strength, particular emphasis being placed on investigating the feasibility of using textural composition data, determined by either scanning electron microscopy (SEX) of etched surfaces or polarized-light microscopy (PLX) of polished coke surfaces, as a basis of predicting the tensile strength of cokes produced from blended-coal charges fro

Abstract:

Il miglioramento per la qualità del frutto dei piccoli frutti, in particolare per tratti altamente soggettivi quali la tessitura della polpa, metaboliti secondari ed aroma è allo stato dell’arte ancora una sfida. Sinora, il miglioramento genetico per texture ed aroma ha sfruttato molto poco metodologie assistite, la MAS per esempio, ed è invece molto dipeso da scelte soggettive dei breeders, in particolare in fasi di selezione molto precoci. L’obiettivo di questa ricerca è stato quello di sviluppare metodologie validate per le diverse classi di piccoli frutti e ciliegia, che possano oggettiva

Abstract:

The aim was to develop new methods for measuring texture of Atlantic salmon (Salmo salar L.) fillets and investigate the genetic basis of flesh quality traits. Firstly, a new tensile strength method was developed to quantify the force required to tear a standardized block of salmon muscle with the aim of identifying those samples more prone to factory downgrading as a result of gaping. The repeatability, sensitivity and predictability of the new technique was evaluated against other common instrumental texture measurement methods. Data from the new method were shown to have the strongest corre

Abstract:

Mechanical parameter characterization of very thin polymer films using digital im- age correlation is performed in this work. At present days DIC is widely used in the construction, food industries, and aviation. Despite advantages when compared to other conventional methods, but users still face difficulties with the analysis of thin polymers like low-density polyethylene (LDPE) and polyethylene terephthalate (PET) thin polymer films. For the application of sprays to obtain the best pattern quality as well as the potential of thin-film material properties tempering from the stochastic pattern
