    The thermal comfort characteristics of bi-layer knitted fabrics have been studied for shuttle badminton sportswear. Bilayerknitted fabrics are developed by changing tuck position in course direction such as 6, 10, 14 and 18 course repeat,keeping the tuck on 12th wale the same. It is observed that the greater the distance between successive tuck points, the betterwill be the air, heat and moisture transfer properties. Bi-layer knitted fabric with slack structure facilitates lower thicknessand mass per unit area, and exhibits better thermal comfort characteristics. By wear trial method, bi-layer knitted fabric withtuck on 18th course and 12th wale shows good rating compared to other bi-layer knitted fabrics. The results are discussed at95% significant level with ANOVA analysis and Friedman one-way analysis of variance

    The comfort properties of different bi-layer knitted structures made from tencel yarn as an outer layer and acrylic/micro-fibre polyester yarn as an inner layer have been studied. Six union fabrics have been produced and then analyzed objectively and subjectively for their comfort properties. The air permeability, water vapour permeability, wicking ability and drying rate are found to be higher and thermal resistance is found to be lower for bi-layer knitted fabric made out of micro-fibre polyester (inner layer) with less tuck points as compared to all other fabrics. The same structure shows good ranking on subjective rating of thermal environment scale. The results are discussed with 95% significant level with ANOVA analysis and Friedman one-way analysis of variance

    Thermo-physiological comfort of the clothing has been studied considering the ability to manage heat and to transfersensible and insensible perspiration to the environment. Four bi-layer knitted fabrics are developed by changing the tuckstitch placement in four different points on wale, such as tuck on 4th, 8th, 12th and 16th wale with same course. It isobserved that the bi-layer knitted fabric with tuck on 12th wale exhibits better air, heat and moisture transfer as comparedto those with tuck on 4th, 8th, and 16th wales. The lower thickness and low mass per unit area exhibit better thermalconductivity, air permeability, water vapour permeability, wicking, moisture absorbency, drying rate and moisturemanagement properties. The less number of tuck stitch shows better thermal comfort characteristics considering bothobjective and wear trial method. The results are discussed with 95% significant level with ANOVA analysis andFriedman one-way analysis of variance

    Red Deer Optimization with Deep Learning based Robust White Blood Cell Detection and Classification Model

    Get PDF
    The use of deep learning techniques for White Blood Cell (WBC) classification has garnered significant attention on medical image analysis due to its potential to automate and enhance the accuracy of WBC classification, which is critical for disease diagnosis and infection detection. Convolutional neural networks (CNNs) have revolutionized image analysis tasks, including WBC classification effectively capturing intricate spatial patterns and distinguishing between different cell types. A key advantage of deep learning-based WBC classification is its capability to handle large datasets, enabling models to learn the diverse variations and characteristics of different cell types. This facilitates robust generalization and accurate classification of previously unseen samples. In this paper, a novel approach called Red Deer Optimization with Deep Learning for Robust White Blood Cell Detection and Classification was presented. The proposed model incorporates various components to improve performance and robustness. Image pre-processing involves the utilization of median filtering, while U-Net++ is employed for segmentation, facilitating accurate delineation of WBCs. Feature extraction is performed using the Xception model, which effectively captures informative representations of the WBCs. For classification, BiGRU model is employed, leveraging its ability to model temporal dependencies in the WBC sequences. To optimize the performance of the BiGRU model, the RDO is utilized for parameter tuning, resulting in enhanced accuracy and faster convergence of the deep learning models. The integration of RDO contributes to more reliable detection and classification of WBCs, further improving the overall performance and robustness of the approach. Experimental results demonstrate the superiority of our Red Deer Optimization with deep learning-based approach over traditional methods and standalone deep learning models in achieving robust WBC detection and classification. This research highlights the possibility of combining deep learning techniques with optimization algorithms for improving WBC analysis, offering valuable insights for medical professionals and medical image analysis

    Development of breathable and liquid/microbes barrier woven surgical gowns for hospital usage

    An attempt has been made to develop a breathable woven surgical gown with antimicrobial and liquid repellent properties by finishing with nanoparticles of silver and fluorocarbon using pad-dry-cure method. Box-Behnken design has been used to optimize the coating parameters, i.e. concentrations of nanosilver (NS), nanofluorocarbon (NFC) and binder. The selected coating parameters has decisive influence on the fabric properties, such as air permeability, moisture vapour permeability, antimicrobial and tensile behaviour. The optimum coating parameters such as concentrations of NS, NFC and binder result in improved air permeability and moisture vapour permeability of the fabric for 3 g/L of NS and 40 g/L of NFC. The antibacterial activity of fabric is found to be higher for increased NS concentration and lower for increased NFC. In case of tensile properties of coated fabrics, the increase in NS concentration increases the tensile strength and decreases the bending modulus of fabrics
