Weaving ‘figured - face flip face - fabric’ using orthogonal weft tapestry weave

The aim of this study is to evolve new compound weave structures by modifying and permuting the existing structures. Basic principles of orthogonal structure and weft tapestry structure have been studied. New ‘Orthogonal Weft Tapestry (OWT)’ weaves are evolved by combining these two weaves and the concepts involved in deriving the new weave have also been developed. The structure of ‘Two in one’ figured fabric available in the field has been analyzed. This fabric is renamed as ‘Figured - Face Flip Face - Fabric (FFFFF)’. Suitability of OWT weave to produce diversified FFFFF has been interpreted. Superimposing the guide graphs for the preparation of weave graph has been worked out using MS Paint to weave this fabric using electronic jacquard. Methodology of making double punching graph for mechanical jacquard weaving is also explored. The feasibilities of weaving these structures are explored using heald-treadle and jacquard shedding devices either separately or in combination. Fabric samples have been developed using mechanical jacquard in handloom. The techno - ergonomics of weaving methods are compared and recorded. It is observed that FFFFF produced with OWT weave has got features like uniqueness in appearance, fascinating utility value, and possibilities of producing exclusive product range

Weaving twill damask fabric using ‘section- scale- stitch’ harnessing

The possibility of weaving figured twill damask using the combination of ‘sectional-scaled- stitched’ (SSS) harnessing systems has been explored. Setting of sectional, pressure harness systems used in jacquard have been studied. The arrangements of weave marks of twill damask using the warp face and weft face twills of 4 threads have been analyzed. The different characteristics of the weave have been identified. The methodology of setting the jacquard harness along with healds has been derived corresponding to the weave analysis. It involves in making the harness / ends in two sections; one section is to increase the figuring capacity by scaling the harness and combining it with other section of simple stitching harnessing of ends. Hence, the new harness methodology has been named as ‘section-scale-stitch’ harnessing. The advantages of new SSS harnessing to weave figured twill damask have been recorded. It is observed that the new harnessing methodology has got the advantages like increased figuring capacity with the given jacquard, less strain on the ends and versatility to produce all range of products of twill damask. It is also found that the new harnessing is suitable to weave figured double cloth using interchanging double equal plain cloth, extra warp and extra weft weaving

A Systematic Algorithm for Denoising Audio Signal Using Savitzky - Golay Method

Audio signal noise reduction is a great task to acquiring noiseless sounds in the noisy environment. But, naturally the audio signals are naturally very noise, which is produced from analog or digital recorders. In this research paper, an efficient noiseless audio reduction system using Savitzky-Golay method is proposed for eliminating unwanted echoes, ripples, etc. Three different audio signals are taken for this work. First one is a human voice in the mobile conversation, which is used for telecommunication purpose. Second is one vehicle sound for usages in security applications. The last one is a music instrumental sound, which used in recording lab. Finally, the proposed system will be compared with the existing noise filters and proved their efficiency with high accuracy, high signal to noise ratio and low elapsed time

An indentured servant: The impact of green card waiting time on the life of highly skilled Indian immigrants in the United States of America

Highlighting the archaic immigration system in the United States of America (US), the present study demonstrates for the first time the impact of green card waiting time on the work and family life of Indian immigrants living in the US. Our present findings show that 93.4% of our participants are very concerned about the estimated green card waiting time in the US. We find 70% of the total participants are seriously thinking at the present time about emigrating to a more visa-friendly country. Also, 30% of the participants have already applied for permanent residency in a visa friendly country and 9% of the participants have already obtained a permanent residency in a more visa-friendly country. Based on these turnover intentions, we estimate the potential direct costs to American organizations due to the green card waiting time to be in the range of $19,303,200,000 -$54,261,724,160. Furthermore, our quantitative results show that the delay in receiving a green card is negatively affecting the work and family/nonwork life of Indian immigrants in the US. These critical issues are in turn causing health issues such as constant fear of unknown (uncertainty and feeling stuck issues due to green card backlog), stress, frustration and chronic health issues. Overall, in addition to the direct losses, the work and family issues caused due to the green card waiting time could result in indirect losses to organizations. We hope that the present findings may be useful to American policy makers and organizational leaders as further decisions are made regarding the American immigration system. In particular, we hope these findings will help to illustrate many serious implications associated with the green card delays and other visa-related proposed policy changes on immigrants, and their spouses, families, and communities.https://scholar.utc.edu/iopsy/1002/thumbnail.jp

Impact of spousal work restrictions and number of dependents on expatriates’ work life and overall life satisfaction

Purpose Our understanding of the challenges and the broader role of spouses of expatriates is extremely limited. The purpose of the study was to examine the impact of spousal work restrictions and number of dependents on expatriates’ work life and overall life satisfaction using qualitative and quantitative analyses Design Data were collected from 416 Indian informational technology professionals working in USA. Hypothesized conditional process models were analyzed using the PROCESS tools. Findings Spousal work restrictions and number of dependents created complications in personal life of expatriates, which interfered with their work life resulting in lower overall life satisfaction. We identified six core classes of challenges faced by spouses of expatriates: financial issues, frustration, loss of respect/low confidence, boredom, social isolation, and domestic tension. Older expatriates were able to better manage the responsibilities associated with number of dependents. More importantly, unlike adjustment, the issues associated with spouse work restrictions did not seem to improve with age or length of time in the USA. Originality Although media outlets have from time to time brought to light the issues faced by spouses of expatriates, the present study provides more credible and complete findings by conducting a qualitative and quantitative research study. To our knowledge this is the first study that has investigated the complications experienced by expatriates’ due to the work restriction (more specifically, visa related) issues faced by the spouses of these expatriates. Our mixed method approach also helps to provide a more comprehensive picture of these complications.https://scholar.utc.edu/iopsy/1001/thumbnail.jp
