TL;DR: In this article, the authors focused on fractional mathematical modelling of dye degradation in textile effluents using the Caputo-Fabrizio fractional derivative without the singular kernel and obtained experimental results showing significant removal of dyes from textile wastewater are compared using modelling results.
Abstract: Textile dyes are untreated discharge into the environment which results in a significant increase in water pollution levels worldwide. Due to the continuous addition of toxic organic dyes, a necessary strategic model is required for the complete degradation of dyes in textile effluent. This paper considers the possibility of biological synthesis of silver and iron nanoparticles and their use in photocatalytic degradation. The immediate change of silver nitrate solution occurring from colorless to brown is observed after the addition of the aqueous leaf extract, indicating the successive reduction of Ag+ ions to the Ag nanoparticles. These formed Ag nanoparticles were subjected to examine the photocatalytic activity under the solar radiation for the degradation of methyl orange. Green synthesized Ag nanoparticles were found to successfully degrade methyl orange up to 95% between 70 hours than the initial exposure time. The absorbance of methyl orange was measured at 465 nm. The present paper is focused on fractional mathematical modelling of dye degradation in textile effluents using the Caputo–Fabrizio fractional derivative without the singular kernel. The iterative Laplace transform method is employed to obtain an analytic solution for the absorption transport equation. The obtained experimental results showing significant removal of dyes from textile wastewater are compared using modelling results. The innovative approach is in outstanding agreement with the findings of the experiment. The mathematical modelling for the dye removal process helps to design suitable environmental management studies to reduce the adverse effect caused by toxic wastewater. Model validation has been shown by comparing analytical simulated solutions with experimental results for photocatalytic degradation using silver and iron nanoparticles as eco-friendly and low-cost agents.

01 Jan 2019TL;DR: A deterministic initialization technique for spherical k-means that considers the distribution of vectors within the space and a related technique to avoid generation of empty clusters is proposed.
Abstract: Document clustering is required when the possible categories into which text data are to be organized are not known. Standard clustering algorithms do not suit well due to high sparsity of term matrices of document corpus. Use of cosine similarity among document vector has proved to give good results. Its use with k-means is referred as spherical k-means. The performance of spherical k-means highly depends on its initialization. This paper proposes a deterministic initialization technique for spherical k-means that considers the distribution of vectors within the space. Experiments on real-life data with skewed distributions are done to compare performance with other initialization methods. A related technique to avoid generation of empty clusters is also proposed.

TL;DR: In this paper, a double gate-all-around (DGAA) MOSFET with high-K dielectric as gate oxide is employed to improve the ON-state current with enhanced device scalability.
Abstract: The present paper is about using three popular performance boosters in a device to battle with deterioration in device characteristics imposed by temperature variation. The dielectric pocket (DP) technology has been utilized in double gate-all-around MOSFET to limit the leakage current problem. Further, high-K dielectric as gate oxide is employed so that ON-state current may be improved with enhanced device scalability. The boosted immunity towards short-channel effects (SCEs) and improvement in the device’s analog performance is demonstrated through comparison between dielectric pocket high-K double Gate-All-Around (DP-DGAA) and double Gate-All-Around (DGAA) MOSFETs with temperature variation from 300 to 500 K by using commercially available ATLAS, a three-dimensional (3D) device simulator from SILVACO.

01 Jan 2020TL;DR: This work has explored the rules of code-switching in Hindi–English code-mixed data and created three models, viz. baseline model, lexicon-based model, and machine learning-based models, and found out the individual accuracies of these models.
Abstract: In this work, we have proposed an efficient and less resource intensive strategy for parsing and analyzing switching points in code-mixed data. Specifically, we have explored the rules of code-switching in Hindi–English code-mixed data. The work involves code-mixed text extraction, translation of the extracted texts to its pure form, forming word pairs, annotation of these using of Parts-of-Speech tags and recognition of the rules that govern switching in code-mixed text. We have created three models, viz. baseline model, lexicon-based model, and machine learning-based model, and found out the individual accuracies of these models.

TL;DR: A systematic review of the numerical and experimental investigation of the flow boiling process has been carried out in this article, where more than a hundred research articles were selected from the publications of Elsevier, SpringerLink, Taylor & Francis, and the American Society of Mechanical Engineers and analyzed.
Abstract: In the past few years, flow boiling has achieved a lot of attention in many industrial applications and thermal systems. To enhance the efficiency of the thermal systems, various working fluids like water, nanofluids, nanorefrigerants, etc. were used and the investigations were carried out using different operating conditions. The main purpose of this literature review is to study the heat transfer rate in different working fluids in the process of flow boiling. In this study, the systematic review of the numerical and experimental investigation of the flow boiling process has been carried out. A Systematic Literature Review (SLR) approach given by Denyer and Tranfield was utilized in this study. More than a hundred research articles were selected from the publications of Elsevier, SpringerLink, Taylor & Francis, and the American Society of Mechanical Engineers (ASME) and analyzed. It was concluded that the previous studies focused on the flow boiling heat transfer in different working fluids and the development of new correlations between the input and output parameters in the flow boiling investigation. Finally, the concluding remarks on the review of the numerical and experimental investigation of the flow boiling process are given.
