We made sure that the study covers the entire process from harvesting and preparing the plant to extracting the fibers and forming them into functional products. The results suggest that water hyacinth, often considered a problematic invasive species, holds significant potential as a renewable material for green product development. This initiative not only encourages the repurposing of natural waste but also supports environmentally responsible design practices and local craftsmanship. After the project was done we came up with the outcomes demonstrate that water hyacinth can be effectively repurposed into eco-friendly goods, contributing to environmental sustainability while encouraging the use of greener materials in design and production. By doing so, the project supports both environmental conservation and the promotion of green alternatives in product design.

Sample is a prototype step, and it makes sure that the end product will match specifications of buyers, i.e. design, fit, fabric and quality. The paper investigates some of the important stages - the receipt of the tech pack and the selection of raw materials, pattern making, sewing, quality control. The focus is especially on the importance of the sample development process in terms of the minimization of errors during the bulk production, decrease in lead times, and an increase in buyer satisfaction. Issues like the communication gap between design and production departments as well as variation in materials are also dealt with. By implementing the case studies and practical observations in the textile industry, the research will calculate best practices to streamline the sampling process. As revealed, the study stresses the role of coordination between merchandising, production, and quality control units in supplying the correct examples that gain confirmation of orders. The work will be of help to textile engineers who need to improve efficiency and quality of the produced textiles especially T-shirts.

Arif-Ur-; Uddin, Shamon; Ashraful, Md. With the continuous downscaling of metal oxide semiconductor field effect transistors (MOSFETs), the performance and scaling limitations have driven emerging innovative device architectures. In this work, we perform a comprehensive simulation-based study of NMOS design and analysis at 14 nm with the test-based simulator, Silvaco TCAD. Our device has a novel “sandwich dielectric” design intended for optimal threshold voltage (Vth) and I-V characteristics (Id-Vd). It is suggested that better electrostatic control can be achieved by using a "sandwich" structure made up of a 0.1 nm zirconium dioxide (ZrO₂) interface layer, a 0.1 nm hafnium dioxide (HfO₂) dielectric layer and a 0.1 nm silicon nitride (Si₃N₄) barrier layer. The gate electrode is tantalum nitride (TaN) with a work function of 4.3 eV, and the source and drain electrodes are aluminum (Al) with a work function of 4.1 eV. Combining these materials with the defined structural arrangement gives better gate control, fewer short-channel effects, and better charge carrier mobility. Finally, our simulation results suggest that our device has considerably enhanced electrical performance. In the form of drain current versus drain voltage (Id-Vd) characteristics, better control of voltage (Vth) and drive currents (Id-Vd) give higher drive currents, lower leakage current, and better switching performance. To address these challenges, we propose a double-gate 14 nm NMOS, a promising device for next-generation low-power, high-power electronic devices. This work contributes critically to the field of nanoelectronics with a detailed study of material selection, structural innovation, and its impact on device performance. Future research on advanced MOSFET architectures and transistor technologies beyond 14 nm can benefit from this study's insights.

Jahid; Islam, Md. Shahidullah In today's cities, save and security pollution are serious concerns. Currently in our society we are suffering from many types of theft and robbery and various types of insecurity. To solve this kind of problem we can use a smart IOT device to provide security to the office court or various save zones. Here we have discussed in complete detail how the activity is done by creating a web and how we can use the object is completely discussed in more detail below. Here we use SIM 800Lto provide information to others to control how the activity is done. How to cross the line with the bin sensor calls to another person's phone and solves the other, and ensures that this device is used to prevent any kind of trouble that miscreants want to make in your security space.
