In this paper, the liquor brands were identified based on the near infrared spectroscopy method and the principal component analysis. 60 samples of 6 different brands liquor were measured by the spectrometer of USB4000. Then, in order to eliminate the noise caused by the external factors, the smoothing method and the multiplicative scatter correction method were used. After the preprocessing, we got the revised spectra of the 60 samples. The difference of the spectrum shape of different brands is not much enough to classify them. So the principal component analysis was applied for further analysis. The results showed that the first two principal components variance contribution rate had reached 99.06%, which can effectively represent the information of the spectrums after preprocessing. From the scatter plot of the two principal components, the 6 different brands of liquor were identified more accurate and easier than the spectra curves.

Urban travel blockage is one of the serious issues which are affecting travelling time. This impact is on economical ability of transportable, non-element of condition, psychosomatic stresses and a movement irregularity on movement. There is a need to indentify clog models for the remarkable impact boil down in peak hour gridlock. The blockage standards can be followed the characteristic located on street with hustle. The clog is created with the overhead conveyed with inconsistent factors and show the way to the fate. These aspects are revealed that they are because of impact of certain trademark impact from elements of land use, street symmetrical, and commute and street organize attributes. This research is encircled on with the staggered distressing variables. GPS information, GIS support tactic is proposed in the assessment for information and a clog model is related to discover clog factors. The current paper compacts with the deliberate the blockage criterions, and clog produced factors for the Dilsukhnagar zone (Gaddianaram region) Hyderabad, Telangana State, INDIA using Principal Component Analysis (PCA) and regression analysis.


Abstract Accurate site-specific forecasting of indoor hourly carbon monoxide (CO) concentrations in school microenvironments is a key issue in air quality research nowadays due to its impact on children’s health. This paper investigated the improvement prediction of multiple linear regression (MLR) and feed forward back propagation (FFBP) by combining them with principal component analysis (PCA) for predicting indoor CO concentration in Gaza Strip, Palestine. Measurements were carried in 12 schools from October 2012 to May 2013 (one academic year). The results suggested that the selected models are effective forecasting tools and hence can be applicable for short-term forecasting of indoor CO level. The predicted indoor CO concentration values agree strongly well with the measured data with high coefficients of determination (R2) 0.869, 0.870, 0.885 and 0.915 for MLR, PCA-MLR, FFBP and PCA-FFBP, respectively. Overall, results showed that PCA models combined with MLR and PCA with FFBP improved MLR and FFBP models of predicting indoor CO concentration, with reduced errors by as much as 7.14% (PCA-MLR) and 56.6% (PCA-FFBP). Moreover, PCA improved the accuracy of the FFBP model by as much as by 3.3%.

Koki baster fish (Carasius auratus) or goldfish, besides as ornamental fish are also used as fish feed and fishing bait which demand tends to increase from year to year. However, from 2012 to 2015, the production of koki baster fish has decreased. This study aims to analyze the application of the management of koki baster fish in Cisaat Subdistrict, Sukabumi Regency, so that a management strategy can be formulated in developing environmentally friendly koki baster in Sukabumi Regency. Data collection was conducted through interviews, observations, questionnaires and documentation. The questionnaires were distributed to 100 respondents who were conducting hatchery for koki baster that scattered in 13 villages in Cisaat Subdistrict. As comparative data, the hatchery of koki baster fish was conducted in the research pond. The variables used are the aquaculture stage (x) consisting of lime dosage, organic fertilizer, anorganic fertilizer, water height, female parent, parent feed, comparison of male and female parent, parent age, larvae feed and duration to number of larvae (y). The variables were analyzed by validity, reliability, multiple regression analysis and principal component analysis using SPSS and Minitab application. Based on the results of multiple regression analysis obtained the relationship between variables in the seeding stage with the number of larvae. Correlation test showed that the variable use of fertilizers had a positive correlation of 69,5% to the number of larvae. Conversely, the variable water height has a negative value on the number of larvae, which is -3.5%. The principal component analysis showed that the variable use of organic fertilizer, anorganic fertilizer and larvae feed was in the first component area. It means that the variable has a large correlation to the number of larvae. The conclusion of there search is the community does not yet have standard in managing fish hatching of koki baster fish, they only rely on experience and habits so that the obtained production is still low. Strategies to increase the production of koki baster fish are need to be standardized on how to farm koki baster fish, standarized koki baster fish and community coaching on the need to carry out the stages of koki baster fish breeding in accordance with the good and environmentally friendly method of fish hatchery.   Ikan koki baster (Carasius auratus) selain sebagai ikan hias juga digunakan sebagai pakan ikan dan umpan pancing yang permintaannnya cenderung meningkat dari tahun ke tahun. Namun demikian dari tahun 2012 hingga 2015, produksi ikan baster mengalami penurunan. Penelitian ini bertujuan menganalisa penerapan manajemen usaha budidaya ikan koki baster di Kecamatan Cisaat Kabupaten Sukabumi sehingga dapat dirumuskan strategi pengelolaan dalam pengembangan budidaya ikan koki baster di Kabupaten Sukabumi yang ramah lingkungan. Pengumpulan data dilakukan melalui wawancara, pengamatan, kuesioner dan dokumentasi. Instrumen yang digunakan adalah kuesioner yang dibagikan kepada 100 orang responden yang melakukan kegiatan pembenihan ikan koki baster di 13 desa yang tersebar di Kecamatan Cisaat. Sebagai data pembanding dilakukan kegiatan pembenihan ikan koki baster di kolam penelitian. Variabel yang digunakan dalam analisis keterkaitan produksi adalah tahapan budidaya (x) yang terdiri atas dosis kapur, pupuk organik, pupuk anorganik, tinggi air, induk betina, pakan induk, perbandingan induk jantan dan betina, umur induk, pakan larva, dan lama pemeliharaan terhadap jumlah larva (y). Variabel-variabel tersebut dianalisis dengan regresi berganda dan analisa komponen utama menggunakan aplikasi SPSS dan Minitab yang sebelumnya dilakukan uji validitas dan reliabilitas.  Berdasarkan hasil analisa regresi berganda diperoleh keterkaitan antara varibael-variabel dalam tahapan pembenihan dengan jumlah larva. Uji korelasi menunjukan variabel penggunaan pupuk berkorelasi positif sebesar 69,5% terhadap jumlah larva.  Sebaliknya variabel tinggi air memiliki nilai korelasi negatif terhadap jumlah larva yaitu sebesar -3,5%.  Analisa komponen utama menunjukan bahwa variabel penggunaan pupuk organik, pupuk anorganik dan pakan larva  berada pada wilayah first component artinya variabel tersebut memiliki korelasi yang besar terhadap jumlah larva. Kesimpulan dari penelitian ini adalah masyarakat belum memiliki standar dalam melaksanakan pengelolaan pembenihan ikan koki baster, hanya mengandalkan pengalaman dan kebiasaan saja sehingga produksi yang diperoleh masih rendah. Strategi untuk meningkatkan produksi ikan koki baster di masyarakat, perlu adanya standar tentang cara budidaya ikan koki baster, standardisasi ikan koki baster dan pembinaan kepada masyarakat tentang perlunya melaksanakan tahapan-tahapan budidaya ikan koki baster sesuai dengan cara pembenihan ikan yang baik dan ramah lingkungan.

This project examines two Iowa lakes to explore the feasibility of using remote sensing technologies for assessing water quality in lieu of actual ground samples. We demonstrate that a principal component analysis of the more than 20,000 remote sensed pixels can be used in a regression analysis to accurately predict total phosphorus levels in Casey Lake on three distinct times in the summer of 2004.
