AbstractThe purpose of this investigation is to propose a multivariate volatility model that takes into consideration time varying volatility and the property of the a-stable sub-Gaussian distribution to model heavy tails. The principal assumption is that... see more

AbstrakMetode gayaberat merupakan metode geofisika yang sudah sering digunakan dalam prospeksi sumberdaya mineral. Parameter objek pencarian berdasarkan variasi pengukuran percepatan gayaberat di permukaan yang diakibatkan oleh variasi perubahan geologi b... see more

In this study, a Numerical model is carried out to study the effect of welding parameters on the temperature variations in Submerged Arc Welding process (SAW) with moving heat source model (Gaussian distribution) by using finite difference method (FDM). T... see more

According to the dynamic characteristics of the rolling bearing vibration signal and the distribution characteristics of its noise, a fault identification method based on the adaptive filtering empirical wavelet transform (AFEWT) and kernel density estima... see more

Naïve Bayes (NB) algorithm is still in the top ten of the Data Mining algorithms because of it is simplicity, efficiency, and performance. To handle classification on numerical data, the Gaussian distribution and kernel approach can be applied to NB (GNB ... see more

The ringed seal (Phoca hispida) has a circumpolar Arctic distribution. Because of its great importance to northern communities and its role as the primary food of polar bears (Ursus maritimus) the ringed seal has been studied extensively in Cana... see more

This work is based on a compilation of benthic foraminiferal data collected in the Aveiro Lagoon and in the adjacent continental shelf and upper slope (center of Portugal). It intends to provide an overall analysis from transitional to the outer continent... see more

Climatic changes have had profound impacts on species distributions throughout time. In response, species have shifted ranges, adapted genetically and behaviourally or become extinct. Using species distribution models, we examined how changes in suitable ... see more

BACKGROUND: Previous studies reported that the distribution of body fat is an important risk factor for coronary artery diseases (CAD) and abdominal adipose tissue is associated with severe CAD. This study was conducted to evaluate the relationship betwee... see more
