Sentiment analysis technique plays an important role in natural language processing to analyze complex human statements. In the last few years, this has become a powerful tool for several social media communication mediums such as WhatsApp, Twitter, Facebook, Instagram, YouTube, LinkedIn, Blog, etc. This paper proposes machine learning (ML) based method data sentiment on text data. The presented is divided into three distinct stages. first stage, pre-processing performed filter and refine...

In the present research work, bismuth ferrite mullite type Bi2Fe4-xZnxO9 (0.0 ≤ x 0.05) nanostructures are prepared by a chemical coprecipitation method and effect of Zn doping concentration on structural, surface topography, dielectric properties is reported. The powder X-ray diffraction pattern nanomaterial shows an orthorhombic crystal structure. Using Scherer's formula, crystallite sizes have been calculated found to be 23.54 45.65 nm, respectively. results atomic force microscopy (AFM)...

Impact of elevated CO2 (free air enrichment) was studied on wheat (Triticum aestivum L. var Kundan) growth, yield and proteome. Elevated significantly impacted both underground (+24%) aboveground (+15%) biomass. Grain weight/plant harvest index were increased by 35% 11.4%, respectively under high CO2. On the other hand, seed protein content decreased 19% enrichment while starch soluble sugar contents 8% 23%, respectively. Wheat leaf proteomics revealed that 50 proteins showing differential...

Emergence of COVID-19 had profound impact on global stock markets, including Indian mar-ket. Key indices like NIFTY50 and Sensex dropped by approximately 40% within two months in 2020, which also affected major mutual funds, leading to significant depreciation their Net Asset Value. Securities Exchange Board India (SEBI) allows funds use deriva-tives for hedging purposes, capped at 100% the scheme's net assets covering debt, equity, derivatives. However, circular amendment SEBI...

In this paper, the dielectric behaviour of coconut oil within frequency range 100 kHz to 30 MHz between temperature °C–50 °C has been observed. The measured values constant and loss show notable variation with for pure oil. It is noticed that (ε՛) (ε՛՛) decreases increasing temperature. in also showed decreasing trend frequency. UV absorbance wavelengths ranging from 200 nm 800 FTIR spectra have recorded. viscosity reported.

From the roots of VERNONIA CINEREA Less. (Compositae) a new triterpenoid has been isolated and characterised as 3beta-acetoxyurs-19-ene ( 1). A further constituent identified lupeol acetate. Structure elucidation made with help spectral analyses.

The demands of power supply increases day by which increase the risk issue due to non-linearity system. Sometimes, a small disturbance may create chain disturbances and results in blackout. To avoid this possibility, intensely islanding is key option some area system detached from affected area. In paper, an Integer Linear Programming (ILP) based optimal placement Phasor Measurement Units (PMUs) has been proposed provide full observability under two contingencies voltage stability...

Dielectric properties of clove oil were determined using an impedance gain phase analyzer (HP 4194 A) at discrete frequencies between 10 kHz and 3 MHz a range temperature 25 °C 45 °C. A micro processor controller based (Julabo F-25) was used for keeping the constant. constant sample is found to decrease with increase in frequency temperature, while dielectric loss decreases but increases temperature. Penetration depth has been calculated help data frequency.

Abstract Gloriosine, the predominant metabolite of Gloriosa superba L., shares chemical properties with colchicine. We analyze microtubule-binding affinity gloriosine at colchicine binding site (CBS) using an in silico-in vivo approach. The In silico docking showed a score (−) 7.5 kcal/Mol towards β-tubulin CBS and was validated by overlapping coupling pose docked ligand co-crystallized 2D plots (Ligplot +) > 85% overlap between ADMET profile accordance Lipinski’s rule five. Gloriosine...

N-[[(Chlorosulfinyl)oxy]methylene]-N-methylmethanaminium chloride (1) is found to be an efficient and mild dehydrating agent for the in situ generation of monophenyl- (4a) diphenyl- (4b) monochloroketenes (4c) directly from corresponding carboxylic acids 2. These ketenes undergo cycloaddition reactions with 1,3-diaza-1, 3-butadienes 5 afford 4(3H)-pyrimidinones 6 azetidones 7, 3-(aryliminomethyl)chromones 8 give [1]benzopyrano[3,2-c]pyridine-3,10[2H]diones 9.

Series of blackouts encountered in recent years power system have been occurred because either voltage or angle instability both together was not detected within time and progressive further degraded the condition, increase loading. This paper presents real-time assessment methodology stability using Phasor Measurement Unit (PMU) with observability load buses only network. PMUs are placed at strategically obtained location such that minimum number PMU’s can make all observable. Data by used...

In this paper, a Mixed Integer Linear Programming (MILP) has been proposed to optimize the number of Phasor Measurements with maximum observability power system, which improves accuracy state estimation. Therefore, one more objective function added into function. Thus problem expresses as multi-objective problem. Measurement Unit (PMU) placements in presence zero injection buses and case single PMU loss have also investigated. The MILP tested on IEEE 30-bus 118-bus test systems. Proposed...

This paper presents the assessment methodology for voltage stability using Phasor Measurement Unit (PMU) with complete system observability. For full power observability, PMU placement is considered and without conventional flow as well injection measurement such that minimum number of PMU's used. Data obtained by are used help L-Index. As gives real time current phasors L-index dependent on admittance values, thus so can be indicator. The case study has been carried out IEEE-14 bus system.
