A theoretical model for the optimization of multilayer antireflection coating for solar cell has been presented on the basis of optical interference transfer-matrix theory. Also, PCID simulation has been carried out to understand the performance of silicon solar cell of antireflection coating. Reflectance calculation for various single, double and three ARCs on silicon substrate are presented. Optical reflection values were deduced with this transfer-matrix formulation via a personal computer using MATLAB program. The reflection loss has been calculated lower than 34.66%, 8.47%, and 5.71% using single, double, and three layers respectively with high refractive index materials. External quantum efficiencies (EQEs) of 65.34% and 81.81% were obtained for the single and double layers ARCs on silicon substrate. It was also observed that the thickness of the antireflection coating should be less about 200 nm. Therefore, it is suggested that the antireflection layers proposed in this study effective to improve the efficiency of solar cell.","PeriodicalId":368690,"journal":{"name":"2019 International Conference on Computer, Communication, Chemical, Materials and Electronic Engineering (IC4ME2)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130074236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydrogel was synthesized by simple free radical graft copolymerization between acrylamide and methyl methacrylate with CMC, in presence of N,Nmethylnebis-acrylamide as crosslinker and potassium persulphate as initiator. For synthesis of two separate antimicrobial hydrogel samples two antimicrobial agents ZnO and TiO2 were added with hydrogel. The products were characterized by physical methods as well as instrumental techniques. It was found that hydrogels with ZnO and TiO2 separately are active against gram positive and gram negative microorganism and have the water absorption capacity of 190 and 173 g/g respectively. Also found that increase in antimicrobial agent percentage water holding capacity decreases but increase antimicrobial activity. From the experimental analysis it can be concluded that the synthesized hydrogel could be a good initiative in the handle of complicacy originates from personal health care products as well as created opportunities for the products to be used in replacement of available petrochemical based super absorbent polymer.","PeriodicalId":368690,"journal":{"name":"2019 International Conference on Computer, Communication, Chemical, Materials and Electronic Engineering (IC4ME2)","volume":"518 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133760334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Continuous wave (CW) operation of OSSLs, that is extremely required for spectroscopy and sensing, is limited by the existence of triplet states of organic molecules. This work focuses on advanced state modeling that considers different important properties of organic gain medium required for the realization of CW-OSSLs. Two approaches are considered to investigate the population inversion (i.e. lasing) of OSSLs upon CW pumping: (i) considering three lowest singlets and two triplet states without the loss of the cavity, and (ii) considering triplet managers into a guest/host gain medium with the loss of the cavity. In the first approach, it is observed that intersystem crossing (ISC)–an inherent property of organic dyes–is the key mechanism that kills CW operation of OSSLs. To overcome this problem, the second approach considers a guest/host system incorporating triplet manager that reduces the effect of ISC on CW lasing. This study indicates important properties of organic gain materials required for CW lasing in OSSLs.","PeriodicalId":368690,"journal":{"name":"2019 International Conference on Computer, Communication, Chemical, Materials and Electronic Engineering (IC4ME2)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130934837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, an approach has been proposed to identify the music evoked brain lobe activation by using spectral features with different musical stimuli. Music has both positive and negative impact on human brain activity. EEG signals from different subjects are collected for three types of music i.e., mild, pop, rock at different sound level in this work. Music are categorized with their PSD value. The PSD value is 0.21 W/Hz, 0. 32W/Hz and 0. S4W/Hz for mild, pop and rock song respectively. According to the activity, human brain is subdivided in to frontal, central and parietal lobe. From logarithmic band power and PSD value, it is shown that for a preferable sound level (15%-55% volume) central lobe of the brain is more activated for mild song and parietal lobe is activated for both pop and rock song.","PeriodicalId":368690,"journal":{"name":"2019 International Conference on Computer, Communication, Chemical, Materials and Electronic Engineering (IC4ME2)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117101618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper aims to present the effects of change in the physical parameter for the Double Wedge airfoil for the different range of Mach number with varying angle of attack. Thermodynamic parameters are studied for two different Double wedge airfoils with half wedge angle 5° and 10° respectively. Double wedge airfoil is analyzed at different angles of attack (AOA). The analysis is done using ANSYS fluent and the $mathrm{k}-varepsilon$ turbulence modeling method is carried out. Numerical simulated data Was generated by using Tecplot. From the simulated result, the coefficient of Lift and Drag has been seen to decrease with the increase in Mach number and decrease in AOA. For same Mach number, increase in half wedge angle increases shock and expansion waves at 0° AONA. And pressure coefficient (Cp) increases in the first half region and decreases in the second half region of the wedge With the increase in half wedge angle.","PeriodicalId":368690,"journal":{"name":"2019 International Conference on Computer, Communication, Chemical, Materials and Electronic Engineering (IC4ME2)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122593854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
