We study Boussinesq convection by computing marginally-stable mean temperature profiles for various Ra which are thermal equilibria of the quasilinear equations. find these solving one-dimensional eigenvalue problems and allowing to evolve according diffusion advection eigenmodes. The mode amplitudes chosen such that maintains marginally stability. multiple modes become important > 10${}^{6}...

We present a method for constructing dependent Dirichlet processes. The new approach exploits the intrinsic relationship between Dirichlet and Poisson processes in order to create a Markov chain of Dirichlet processes suitable for use as a prior over evolving mixture models. The method allows for the creation, removal, and location variation of component models over time while maintaining the p...

ABSTRACT
 
 This study aimed to determine the land suitability class for soybean, corn and peanut plants in Kamno Sari Village, Jagebob District, Merauke Regency. Data analysis was carried out by matching or compare requirement plant properties of area. The results this comparison shows level corn, soybeans peanuts which includes S1 (very suitable), S2 (appropriate), S3 (marginally ap...

Abstract Irrigation development necessitates suitable lands for higher yield production and the of long-term irrigation systems. The purpose this research was to identify appropriate in Minch Yekest watershed West Amhara, Ethiopia. Geospatial multi-criteria decision-making techniques were used study. For land suitability analysis surface irrigation, slope, use, altitude, distance from water sou...

Stability limits place restrictions on the economic operation of power systems. Calculation of these limits is therefore very important, but has traditionally been quite difficult. This paper proposes an iterative algorithm for determining parameter values that result in marginal stability of a system. (A system is marginally stable for a particular disturbance if the postdisturbance trajectory...

I summarize the recent work on market (in)efficiency, highlighting key elements why financial markets will never be made efficient. My approach is not by adding more empirical evidence, but giving plausible reasons as to where inefficiency arises and why it’s not rational to arbitrage it away.
