In this paper we intend to examine the application of Kullback-Leibler, Hellinger and LINEX loss function in Dynamic Linear Model using the real price of oil for 106 years of data from 1913 to 2018 concerning the asymmetric problem in filtering and forecasting. We use DLM form of the basic Hoteling Model under Quadratic loss function, Kullback-Leibler, Hellinger and LINEX trying to address the ...

In recent years, green synthesis of nanoparticles has attracted a great attention because of medicine and biological applications. In this work, bismuth oxide nanoparticles (Bi2O3 NP) was prepared via green synthesis using mentha pulegium aqueous extract after 24 h at 90°C. The product was characterized by ultraviolet-visible (UV-VIS) spectrophotometer, Fourier transform infrared (FTIR), X-ray ...

This paper presents two techniques for reducing the power consumed by database servers. Both techniques are intended primarily for transactional workloads on servers with memory-resident databases. The first technique is databasemanaged dynamic processor voltage and frequency scaling (DVFS). We show that a DBMS can exploit its knowledge of the workload and performance constraints to obtain powe...

We construct a single-particle Green function, which can identify topological phases of interacting systems. The function is defined by an effective Bloch Hamiltonian, equal to the inverse full particles at zero frequency. Topological systems be detected coincidence poles and zeros diagonal components constructed function. crosses in momentum space are also signal nontrivial phases. As demonstr...
