Pan-sharpening (PS) is based on remote sensing and image fusion approach thatproduces a high spatial resolution multi-spectral image by merging spectral information from a low spatialresolution multispectral (MS) image with intrinsic spatial details from a high spatial resolution panchromatic(PAN) image. Traditional pan-sharpening methods continue to seek for a fused image that contains thenecessary spatial and spectral information. This work proposes a pan-sharpening method based on a recentinvention, convolutional sparse representation (CSR). Geometric structural characteristics are extracted fromthe PAN image using a CSR-based filtering procedure. The challenge of learning filters, convolutional basispursuit denoising (CBPDN), is handled using a modified dictionary learning method based on the concept ofAlternating Direction Method of Multipliers (ADMM). The retrieved details are put into MS bands usingapplicable weighting coefficients. Because the proposed fusion model avoids the standard patch-basedmethod, spatial and structural features are preserved while spectral quality is maintained. The spectraldistortion index SAM and the spatial measure ERGAS improve by 4.4 and 6.2 percent, respectively, whencompared to SR-based techniques. The computational complexity is reduced by 200 seconds when compared \u0000to the most recent SR-based fusion technique. The proposed method's efficacy is demonstrated by reduced-scale and full-scale experimental findings utilising the QuickBird and GeoEye-1 datasets.","PeriodicalId":274343,"journal":{"name":"JOURNAL OF ADVANCED APPLIED SCIENTIFIC RESEARCH","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130118815","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 presents a fast boundary element algorithm in seismic analysis of two-dimensional elastic media for the first time. In the proposed method, instead of the usual node-to-node, a method of cell-to-cell relation method is implemented by hierarchy tree structure. In addition, the Plane Wave Time Domain algorithm and the Iterative method has been used to solve a system of equations which increases the speed of network convergence, especially in high degrees of freedom that has not been used in the study of the seismic waves’ response yet. Nowadays, this new algorithm adopts for investigating the response wave fields of electrical, magnet [1], acoustic and thermal conductivity which are discussed in details in various articles and books.","PeriodicalId":274343,"journal":{"name":"JOURNAL OF ADVANCED APPLIED SCIENTIFIC RESEARCH","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116765963","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}

Soap nut (SN), whose botanical name is Sapindus mukorossi, seems to have similar properties. It is saponin, the major component present in soap nut, which is responsible for its antimicrobial and film forming property. There are many reports to support that up to a certain limit saponin can be used for edible purpose.2In this study the synergistic preservative effect of chitosan and soap nut aqueous solutions on fruits and vegetables was evaluated. At first, the antimicrobial effect of CS, SN and [CS+SN] in the film form was studied against Staphylococcus aureus and Escherichia Coli. As expected the film CS+SN exhibited more antimicrobial activity with 25 mm and 23mm zone of inhibition against Staphylococcus aureus and Escherichia Coli respectively. The potential of CS+SN as a preservative was evaluated by spraying a known concentration on different regional fruits like lemon, banana, tomato and orange. Different concentrations of [CS+SN] - 250ppm and 125ppm, along with CS-500ppm, SN-500ppm and water, were compared, where water served as the control. Fruits sprayed with [CS+SN]-250ppm solution, showed significant delay in the change of weight loss, decay percentage, pH, as compared to control fruits. It also maintained better visual quality than CS and SN coated as well as control samples. These findings suggest that [CS+SN], with its synergistic preservative potential will maintain the fruit quality and lead to better acceptance by consumers. Thus Chitosan along with soap nut solution will be a cost effective, eco-friendly and easy to utilize preservative system.","PeriodicalId":274343,"journal":{"name":"JOURNAL OF ADVANCED APPLIED SCIENTIFIC RESEARCH","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117030815","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}

Sorption equilibrium time was observed in 60 min. The equilibrium adsorption data were correlated with Langmuir and Freundlich isotherm models. The kinetics of the adsorption process was tested by pseudo-second order, Elovich and intraparticle diffusion models. It was shown that adsorption of copper (II) ions could be described by the pseudo-second order kinetic model. Thermodynamic parameters such as Gibbs free energy (ΔG0), the enthalpy (ΔH0) and the entropy change of sorption (ΔS0) have also been evaluated and it has been found that the adsorption process was spontaneous, feasible, and exothermic in nature. The results indicated that activated KANC can be used as an effective and low-cost adsorbent to remove Cu (II) ions from aqueous solution.","PeriodicalId":274343,"journal":{"name":"JOURNAL OF ADVANCED APPLIED SCIENTIFIC RESEARCH","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123693925","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}
