Variabilitas cuaca dan iklim di Indonesia disebabkan oleh berbagai macam faktor skala ruang waktu, baik yang bersifat lokal, regional, maupun global dengan variasi waktu harian, bulanan, musiman, hingga tahunan. Pada harian intramusiman, MJO menjadi utama variabilitas wilayah tropis, sedangkan pada tahunan, El Nino La Nina memberikan kontribusi terbesar. Penelitian ini bertujuan untuk mengkaji ...

We introduce the notion of a generalized diierential on an abstract measure space and construct corresponding strong and weak Sobolev spaces. We show that the validity of a \weak equals strong"{theorem, i. e. the coincidence of the weak and strong Sobolev space, implies Markov uniqueness for the diiusion operator corresponding to the generalized diierential. Applications include a necessary and...

BACKGROUND To date, the use of traditional nucleic acid amplification tests (NAAT) for detection of HIV-1 DNA or RNA has been restricted to laboratory settings due to time, equipment, and technical expertise requirements. The availability of a rapid NAAT with applicability for resource-limited or point-of-care (POC) settings would fill a great need in HIV diagnostics, allowing for timely diagno...

We reduce the construction of a weak solution of the Cauchy problem for the Navier-Stokes system to the construction of a stochastic problem solution. Under suitable conditions we solve the stochastic problem and prove that simultaneously we obtain a weak (generalized) solution to the Cauchy problem for the Navier-Stokes system. RESUMEN Nosotros reducimos la construcción de una solución débil d...

The p-version of the finite element method is analyzed for quasilinear second order elhptic problems in mixed weak form Approximation properties of the Raviart-Thomas projection are demonstrated and L-error bounds for the three relevant variables in the mixed method are denved Résumé — Nous analysons la version-p de la méthode d'éléments finis mixtes pour des problèmes quasihnéaires elliptiques...

The NINA detector on board the Resurs-01 No. 4 satellite (835 km, 98 inclination) is equipped with particle trackers based on silicon strip detectors. From the energy deposited in each of its silicon layers the mass, the momentum direction and energy of incident particles have been determined. The resolutions in mass and energy allow identification of H and He isotopes over the 10–50 MeV/n ener...

In this paper, we study the rate of convergence of a symmetrized version of the classical Euler scheme, applied to the discretisation of the solution of a stochastic differential equation with a diffusion coefficient function of the form |x|, α ∈ [1/2, 1). For smooth test functions, we show that the weak error is of order one as for the classical Euler scheme. More over, the symmetrized version...
