There is certain yarn parameter which decides the quality of 100% cotton fabric. In this the author used plain weave to produce fabric but only change is arrangement of warp and weft with differential twist direction. Then this sample is tested for the different fabric properties to check its performance. It helps to check effect of twist direction and arrangement of warp and weft on these properties. The purpose of this study is to explore the effect of different ply yarn twist direction on various fabric properties. It helps in deciding the suitability of a fabric used for the crease resistant purpose. In this research the four sets of fabrics with different combination of warp and weft threads having the 'S' and 'Z' directional twists were used. The fabric samples were tested for different types of tests like: Air permeability, fabric elongation and abrasion resistance. © 2017, Textile Association (India). All rights reserved.

In this paper, an application of neural networks is suggested for MPEG video traffic prediction. The aim is to predict the future frame of video stream. In single frame prediction problem, we have used the information of previous frame sizes to predict the next frame size of the sequence. As a tool for the prediction, we use multilayer perceptron feedforward neural network. (FMLP). The purpose of our work is to construct suitable neural networks and evaluate the performance of the network for variable bit rate video prediction. We use video traces from [5]. The results of designed predictor indicate that if the networks are trained with a portion of a high activity level trace, it can predict the traffic of other traces of same movie with a reasonable degree of accuracy. © 2010 IEEE.

Formants are the frequency parts of speech and singing signal those closely describe the human vocal tract geometry. Considering the growing importance of the formants, they are considered the important subject of many work. In this sense, we present two techniques for the estimation of formants, one combining Wavelet with Linear Predictive Coding (LPC) and the other combining Wavelet with Cepstral analysis. The proposed approaches uses multi-resolution analysis of wavelet transform to accurately extract the formants. The proposed techniques were tested on corpus of [a],[e],[i],[o],[u] vowels to extract speech formants, whereas singing formants were analyzed using capella singing voice of trained singers. The paper compares the formant structures of speech and singing, revealing the well-known difference, the presence of an additional formant in singing, called the singing formant, at frequencies between 2500-3000 Hz. The experimental results show the superiority of the proposed techniques in extracting formants over the conventional methods like LPC and Cepstrum. © 2014 IEEE.

Extraction of significant and dominant features from possibly large set of database is a crucial task. The Performance of feature extraction technique depends on the dimensions of generated features and reconstruction. In this paper we provide a comparative study of different feature extraction techniques like Discrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT), Principle Component Analysis (PCA), Local Binary Pattern (LBP), DCT+Gabor, DWT+ Gabor etc. and each technique is compared with each other based on Sebastian Marcel static hand postures database[24] consisting of six postures. We have used Neural Network to compare the performances of feature extraction techniques based on Recognition Accuracy (RA), False Acceptance Rate (FAR), False Recognition Rate (FRR) and also dimensions. We found that fusion of LBP and Gabor, DWT and Gabor provides good results. © 2014 IEEE.

The textile industry is today more competitive and much cost conscious industry. At every stage of processing the objectives is to reduce the cost and machine manufacturers are concentrated to produce more sophisticated and less expensive machine with higher production rates, and cotton processors in order to remain viable. Rotor technology is very upcoming unconventional and economical method for yarn manufacturing because of its very high productivity, automation and elimination of roving and winding process. Conventionally it was used for coarser yams or for the waste spinning but now a day's textile technologists are trying to use this method of yam manufacturing for high quality yarns. Generally in the rotor spinning rotor is the main element which affects the yarn quality produced on it so that, in this study we have tried to analyze the effect of rotor configuration by taking different rotor diameter, naval size and rotor finish. In rotor spinning rotor decides the fibre accumulation, fibre bundling and fibre twisting during the formation of yarn. © 2015, Textile Association (India). All rights reserved.

All textile manufacturers worldwide are trying to develop their machines to improve not only quality, productivity and energy consumption, but attempts are made to make processing eco-friendly. Most textile wet processing involves the use of chemicals for assisting, accelerating or retarding its rates, and must be carried out at high temperature. Due to high consumption of chemicals, it not only increases the C.O.D in waste water but also leads to toxicity and thus effecting the environment very badly as the chemicals used finally turns into the complexes that can hardly be recycled and we cannot wait for a wakeup call by the environment as it can prove highly disastrous. Recendy, India has promised to reduce the emission of carbon dioxide by 20-25% by 2020. The promise cannot be fulfilled unless effluents are reduced. Need of the day is to produce a machine to carry out dyeing with very less water or eliminate the use of water, and using unconventional sources of energy like solar energy. However the conventional processing is relatively cheap but creates pollution problems. To overcome these difficulties, it is necessary to develop the new techniques and the answer is here i.e. Ultrasonic Technique, Plasma Technology, Air Dyeing, Electrochemical Reduction and Radio Frequency.

Polyester false twist draw textured and air- jet textured yarns were manufactured using draw and air jet texturising machines. Both the textured yarns were manufactured using same feed yarn and draw ratio. The two textured yarns were evaluated for bulkiness, tensile, shrinkage and moisture management characteristics. The draw textured yarn was found to have higher strength, breaking elongation, dimensional stability, moisture absorbency, moisture transportation and lower bulk as compared to air jet textured yarn. © 2015, Textile Association (India).

XCD Search-An XML Context-driven Search Engine answers both Keyword-based and Context-driven queries using stack-based sort merge algorithm. It performs well with all criteria of queries against XML trees, except queries submitted against a document, whose XML tree contains a parent node and child interior node, both having same Taxonomic Label and both have child/children data node(s) and/or attribute(s). In this paper we propose An Improved XML Context-driven Search Engine. It uses all the techniques used in XCD Search, in addition to new techniques that handle the type of XML trees mentioned above, which XCD Search does not handle well. We evaluated this system experimentally and compared with original version of XCD Search. The results showed remarkable improvement. © 2011 IEEE.

It is known that plasmas can be used to alter material surfaces by removing surface layers, to activate the surface to become more polar, to passivate surfaces, making them less polar, and to deposit thin films. Plasma treatment of textiles was examined in the 1960s without much success; however, in response to the electronics industry's need, significant developments have been made in plasma tools since then. For example, processes in the 1960s had 109 excited particles/cc compared to 1012/cc in the 1990s. This means there is a great deal more energy available without developing excessively high temperatures. Advances in plasma technology have led to the development of coatings which increase surface hardness and lower the coefficient of friction of metals. Low-temperature plasma technology-both glow discharge under reduced pressure as well as barrier discharge under normal pressure-is well established in different industrial applications. Since recent times, however, the plasma technology is being introduced in textile industry as well. Fields of application are desizing. functionalising, and design of surface properties of textile fibres. Plasma technology is suitable to modify the chemical structure as well as the topography of the surface of the material. Examples of natural as well as man-made fibres prove the enormous potential of plasma treatment of textile materials. It has proven to be successful in shrink-resist treatment of wool, with a simultaneously positive effect on the dyeing and printing. Not only the chemical structure of the surface is modified using different plasma gases, but also the topography of the surface. A highly hydrophobic surface with a particular surface topography in contact with water is extremely dust- and dirt-repellent and hence should be also repellent to bacteria and fungi. Man-made fibres to be used under chemical stress are modified with diffusion-barrier layers on their surfaces without modifying the bulk properties; hence, the stability of those fibres is significantly improved.
