The main purpose of this study was to examine the applicability of geostatistical modeling to obtain valuable information for assessing the environmental impact of sewage outfall discharges. The data set used was obtained in a monitoring campaign to S. Jacinto outfall, located off the Portuguese west coast near Aveiro region, using an AUV. The Matheron’s classical estimator was used the compute...

In this paper, we studied and formulated the relapsed SIR model of a constant size population with standard incidence rate. Also, the optimal control problem with treatment and vaccination as controls, subject to the model is formulated. The analysis carried out on the model, clearly showed that the infection free steady state is globally asymptotically stable if the bas...

This research provides information about land prices in Jakarta by classifying using the Random Forest method. Where is a data mining technique that usually used to perform classification and regression. one of best methods. It found accuracy will increase dramatically as result voting select class types ensemble tree growth. The method helps providing with per meter less than IDR 15 million, p...

A geometrically anisotropic spatial process can be viewed as being a linear transformation of an isotropic spatial process. Customary semivariogram estimation techniques often involve ad hoc selection of the linear transformation to reduce the region to isotropy and then tting a valid parametric semivariogram to the data under the transformed coordinates. We propose a Bayesian methodology which...

Geostatistika merupakan ilmu yang berfokus pada data spasial. Dalam geostatistika terdapat metode pendugaan untuk menangani variabel mempunyai nilai bervariasi dengan berubahnya lokasi atau tempat disebut teregionalisasi. Metode digunakan teregionalisasi kriging. ordinary kriging perlu memperhitungkan semivariogram. Hujan suatu proses jatuhnya air berasal dari awan ke bumi. di ukur memalui cura...

objectives: the purpose of this study was to compare the accuracy of implant position transfer and surface detail reproduction using two impression techniques and materials. materials and methods: a metal model with two implants and three grooves of 0.25, 0.50 and 0.75 mm in depth on the flat superior surface of a die was fabricated. ten regular-body polyether (pe) and 10 regular-body polyvinyl...
