The goal of this paper is to present a texture-oriented method combined with dimensional reduction that can be used to train the Single-Layer Neural Network (SLN), Back Propagation Algorithm (BPA), and Cerebellar Model Articulation Controller (CMAC) for identifying facial expressions. The proposed methods are known as intelligent methods because they can account for variations in facial expressions and thus perform better for untrained facial expressions. Conventional methods have limitations in that face expressions must adhere to certain guidelines. Gabor wavelet is used in different angles to extract possible textures of the facial expression to achieve expression detection accuracy. The higher dimensions of the extracted texture features are further reduced by using Fisher's linear discriminant function to improve the proposed method's accuracy. For training the proposed algorithms, Fisher's linear discriminant function is employed to turn a higher-dimensional feature vector into a two-dimensional vector. Angry, disgust, happiness, sadness, surprise, and fear are some of the facial emotions that are used. The proposed algorithms are compared in terms of performance.","PeriodicalId":437958,"journal":{"name":"Current Approaches in Science and Technology Research Vol. 12","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125836512","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}

The lipids degradation capability of lipid-degrading bacteria was investigated for possible application in treatment of lipids-contaminated wastewater. A total of 102 bacterial isolates were isolated from 43 vegetable oil- contaminated wastewater samples of many food processing plants and restaurants in 5 districts of CanTho city, Vietnam on LB medium. Among of them, 61 isolates formed clear zones on Tw20 medium. Out of the 61 bacterial isolates, 11 formed large halos which had the potential ability to degrade vegetable oil in the contaminated wastewater. These 11 baterial isolates were identified by PCR technique and DNA sequencing. The results of DNA sequencing were compared with GenBank database of NCBI by BLAT N software. The DNA sequences of selected isolates showed high degrees of similarity to those of the GenBank references (between 97% and 99%). Two isolates belonged to Bacilli (18.18 %) and nine isolates belonged to Gammaproteobacteria (81.82%). Based on Pi value (nucleotide diversity), Gammaproteobacteria group had the highest Theta values. Theta value (per sequence) from S of SNP for DNA polymorphism were calculated for each group and the 11 lipid-degrading strains had high genetic diversity. The results proposed Acinetobacteria soli strain AL3 as a potential bioproduct for wastewater treatment because of its high ability of lipid degradation and biosafety.","PeriodicalId":437958,"journal":{"name":"Current Approaches in Science and Technology Research Vol. 12","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122857856","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}

However in, the hot and dry climatic zone increase in daylight availability may result into thermal ingress. This might lead to excess energy conservation. The aim of this paper is to evolve the methodology which could be used as a pre design tool for assessing the lighting provisions and thermal performance of spaces within buildings adopted by designers during the design process. The field measurements were conducted on the liveable spaces of a dwelling unit of the Nagpur region. Simulation studies using Ecotect Analysis 2011 was conducted for both illumination and thermal energy. The field measurements were compared with the simulated results. It has been found that the percentage difference (PD) between the Ecotect measurements (EM) and field measurements (FM) for both thermal loads and an illuminance level was less than 15%, the simulated model was considered precise for further study. The result imply that the simulated model would be ample for designers to evaluate the parameters associated to wall to window ratio, shading devices with respect to orientation of the building which helps to achieve the optimum useful daylight index.","PeriodicalId":437958,"journal":{"name":"Current Approaches in Science and Technology Research Vol. 12","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130976140","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}

Wearable antenna has the wearable and textile properties bending in 2D, which shows the flexibility for the wearable electronic devices. Since the performance of the antenna is working on ISM band, it is perfectly suitable for biomedical applications. In the proposed antenna silk substrate is chosen for implementation because of its low SAR and is placed on the thyroid gland to detect the cancer cells. The performances of the antenna were varied, when it is placed on the thyroid gland of the human tissue, Tissue properties were considered and analyzed within and without cancer affected areas. Since cancer cells are more water content tissues, the gain and electrical conductivity performance were found changed. While placing the antenna on thyroid gland it is also observed that there is a change in working frequency of the Z-patch silk substrate wearable antenna. Hence by using this proposed antenna on human body and by appraising its results, the presence or absence of thyroid cancer can be detected. The simulated results have been tabulated and measured. The results of the fabricated proposed antenna S11 have been shown by using the network analyzer.","PeriodicalId":437958,"journal":{"name":"Current Approaches in Science and Technology Research Vol. 12","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121630469","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}
