It is a significant process to automatically extract ellipses or elliptic image features in highly precise vision detection, especially to achieve rapid as well as accurate detection in complex environment. Fortunately, this paper provides an approach to solve the problem. We firstly detect the edge of images by using sub-pixel edge detection algorithm, and then determine the elliptical shapes, and eliminate the non-ellipses. For the complicated context and taking into account the occlusion of ellipses, we integrate the robust Hough transforms and slip window into randomized algorithm based on least square approach with the purpose of having got the veracious ellipse parameters, which proves that the approach is available for images in stability and accuracy.

Abstrak: Inklusi Keuangan dan Literasi Keuangan terhadap Kinerja dan Keberlangsungan Sektor Usaha Mikro Kecil Menengah. Suatu kinerja unggul dan bisnis yang berkelanjutkan dapat terwujud apabila terdapat upaya-upaya strategis yang dilakukan. Jawa Timur merupakan salah satu provinsi dengan jumlah UMKM yang cukup banyak memiliki peluang yang besar untuk meningkatkan perekonomian Indonesia. Penelitian ini dilakukan untuk menganalisis pengaruh inklusi keuangan dan literasi keuangan terhadap kinerja dan keberlangsungan sektor UMKM yang terdapat di Kota Surabaya. Penelitian ini merupakan penelitian kuantitatif dengan inklusi keuangan (INKA) dan literasi keuangan (LIKA) sebagai variabel independen, serta kinerja usaha (KIUS) dan keberlangsungan usaha (KEUS) sebagai variabel dependen. Sampel pada penelitian ini berjumlah 113 UMKM yang kemudian dilakukan analisis dengan pendekatan Partial Least Square. Hasil penelitian menyimpulkan bahwa inklusi keuangan tidak berpengaruh terhadap kinerja dan keberlangsungan sektor UMKM. Sedangkan literasi keuangan memiliki pengaruh yang terhadap kinerja dan keberlangsungan sektor UMKM.Kata kunci: Inklusi Keuangan, Literasi Keuangan, Kinerja Bisnis, Keberlangsungan Bisnis, UMKMAbstract: Financial Inclusion and Financial Literacy on the Performance an Sustainability of the MSMEs. Excellent performance and sustainable business can be realized if there are strategic efforts. East Java, as one of the Province with a large number of MSMEs that have a great opportunity to improve the Indonesian economy. This study was conducted to analyze the effect of financial inclusion and financial literacy on the performance and sustainability of MSMEs in Surabaya. This research is a quantitative study with independent variables are financial inclusion (INKA) and financial literacy (LIKA), and the dependent variables are business performance (KIUS) and business continuity (KEUS). The sample in this study amounted to 113 MSMEs which were then analyzed using the Partial Least Square approach. this study concludes that financial inclusion has no effect on the performance and sustainability of MSMEs. while financial literacy has a influence on the performance and sustainability of MSMEs.

The Relationship

The purpose of this study is to examine and analyse the effect of local governments’ ability on the relationship between budget turbulence and budget deviation. The study sample uses the regional budget (APBD) report and realization of a number of districts/cities throughout Indonesia encompassing the 2014-2017 period, while the analysis covers the period from 2015-2017. This study uses the least square approach with EViews analysis tool version 10 to test the hypothesis. Result of the study shows that budget turbulence has a positive and significant effect on budget deviation. The result also shows that the capacity of local governments can reduce the influence of budget turbulence on the budget deviation. Sensitivity tests using proxies of local governments not sampled by the main test also show consistent results. Finally, sensitivity test by area category proves that for the three categories, mainly western, central, and eastern Indonesia, the results are consistent with the main test results. The contribution of this study to the policies of the local governments is aimed to enhance efficiency of spending and increase productive spending to support the priority of government programs and encourage efficient, innovative and sustainable financing while maintaining the investment climate. Through several of these alternatives, the local government can overcome the conditions of resource instability that can threaten the effectiveness of the implementation of various programs.

Nusselt Number Correlation

The Bootstrap Statistical method is applied for estimating the accuracy of the convective heat transfer non linear correlation of AL2O3 nanofluid working as cooling fluid. The flow experiment considers laminar and turbulent regimen through an array of aluminum microchannels and millichannels heat sink, taking into account the Volume Fractions, Reynolds, Peclet and Prandtl numbers. The β’s parameters are estimated with nonlinear least square approach. StatGraphics® was used, considering the Gauss-Newton algorithm with Levenberg-Marquardt modifications for global convergence. Correlation for Nusselt number is presented and suggestions for future experimentation are presented in order to improve the accuracy of the regression.

Damage Depth

To measure the depth of fire-damaged concrete by ultrasonic method, it was traditionally assumed that the concrete of the fire-damaged structural member could be simply classified into damaged layer and undamaged layer. Based on it, the damage depth can be calculated with a series of single-sided ultrasonic measured data. This method is simple and convenient but less accurate in the practical application. To improve the algorithm, hyperbola curves are adopted to simulate the varying of damage with depth in this paper. And parabolic curves are adopted to simulate the traces of ultrasonic wave in different measured distances. Therefore, the minimum propagation time can be obtained under different damage conditions. Through comparing the calculating results and measured data in different measured distances, the most likely damaged trend can be determined with least square method. At the end of this paper, examples are demonstrated to prove this algorithm feasible and more accurate than the traditional one.
