Different chemical reaction models (first-order, second-order, and nth-order) six different model-fitting techniques (nth-order, Friedman, Freeman−Carroll, Chang, ASTM E689, the standard deviation minimization technique (SDMT)) are used to evaluate kinetics triplet (E, ln k0, n) for thermal decomposition of waste soft drink poly(ethylene terephthalate) (PET) bottles (M/s Coca Cola). Nonisothermal experiments at four heating rates (5, 10, 15, 25 K/min) isothermal temperatures (685, 693, 703,...

We employed a hybrid genetic algorithm (HGA) technique (GA coupled with the local optimization (LOA)) and model-free (isoconversional) method of analysis LOA to obtain optimized kinetics triplet values for catalytic (ZSM-5) noncatalytic decomposition waste low-density polyethylene (LDPE) sample. Catalytic starts completes at much lower temperatures but continues wider range indicating slower process in comparison one. Contrary single peak observed LDPE, ZSM-5 catalyzed shows multiple peaks...

The present study mainly focussed on the effect of different thermal pretreatments Ageratum conyzoides. Thermal pretreatment reduced hydrolysis period and, at same time, increased biogas production as compared to untreated effects four techniques, i.e., hot air oven, microwave, autoclave, and water bath anaerobic digestion conyzoides were studied. Autoclave was found be more efficient, followed by a bath, microwave pretreatments. enhanced solubilization. Simultaneously, increment in volatile...

Parthenium hysterophorus, Lantana camara and Ageratum conyzoides are considered among the world's top twenty notorious terrestrial weeds due to their reproduction potential hazardous nature. They can grow within a few weeks cover entire agricultural land (Parthenium hysterophorus), forest (Lantana camara) native vegetation (Ageratum conyzoides). These difficult manage as they re-grow miraculously even after being completely obliterated. The availability of in abundance make them attractive...

An implementation of neonatal cry classification on an embedded platform is presented in this paper. It was perceived that diagnosis the cause human baby can be aided with electronic device which help parents and doctors comfort their baby. The present work gives detail such a mobile runs Android operating system includes application for classification. proposed features automatic detection cry, four classes ("Hunger", "Pain", "Wet Diaper" "Others"), displaying taking user feedback each cry....

Invasion of Lantana camara all over the world and its management is a global problematic issue. Its rapid growth competition with natural resources such as space, water, nutrients other plants, reasons for demand to manage this noxious weed. This study was done optimize ideal food microorganism (F/M) ratio. Different ratios 1, 1.5, 2 2.5 were studied along one control where only cow dung kept. Highest methane production obtained from F/M ratio 1.5 (195.5 ± 8 mL CH4/g VS) cumulative it 4801.5...

The current study was performed to explore the electrohydrolysis pretreatment on A. conyzoides. After electrohydrolys pretreatment, reduction of hydrolysis period and enhancement biogas production observed. This novel also shows efficiency in terms increasing volatile fatty acids (VFA) soluble chemical oxygen demand (sCOD) as compared with untreated conyzoides/control. Highest sCOD VFA observed around (750 ± 5 mg/L 9600 48 mg/L) at 30 V for 20 min, which is 27.08% 56.66% respectively....

In this paper authors have presented a novel approach for Human Machine Interaction (HMI) that can be used to give alphabets as input internet browser in an interactive Set top box with added facility. The device is designed MEMS sensor which worn on fingertip send alphabetical set box. Users write the English alphabet capital letter by just using attached their hand. Then data undergone some filtering and finally it sent recognition module. features consists of chain code based...

This study's main objective is to apply electrohydrolysis pretreatment on P. hysterophorus reduce the hydrolysis phases and enhance biogas production. Electrohydrolysis shows efficiency of increasing VFA sCOD compared with untreated P.hystrophorous. at 20 V for 40 min highest around (17600 ± 21 mg/L 780 24 mg/L) respectively, which 50.17% 33.33%. Therefore, a biochemical methane potential trial was studied 50days, where cumulative yield observed 4242 17 mL CH4/g VS after in it 3063 29 VS....

A low-cost, sensitive, laser-based (Helium Neon; He-Ne) optical Fourier-transformed (multiplexed) spectrometer has been constructed for the quantification of suspended particulates in air. The optomechanical features are presented together with a theoretical framework its operation. apparatus is calibrated by using standard commercial spectrophotometer and successfully used to detect smoke various densities. simplicity design sensitivity measurement would expectedly attract high school...
