It is generally predicted that global warming will stimulate primary production and lead to more carbon (C) inputs to soil. However, many studies have found that soil C does not necessarily increase with increased plant litter input. Precipitation has increased in arid central Asia, and is predicted to increase more, so we tested the effects of adding fresh organic matter (FOM) and water on soi...

In the present paper, we propose the global full orthogonalization method (Gl-FOM) and global generalized minimum residual (Gl-GMRES) method for solving large and sparse general coupled matrix equations

Fermented mixtures containing fish-offal meal (FOM) and mulberry leaf meal (MLM) were used as protein supplement to partially replace fish meal (FM) in the formulation of diets for the Indian minor carp Labeo bata. The diets included a reference diet (20 % FM), three diets of fermented mixture of FOM and MLM (T2–T4) replacing 50 to 75 % of FM. Formulation of diet with 30 % FOM, 24 % MLM and 5 ...

In this paper, a new approach to optimize phase noise and figure of merit (FoM) in class-C oscillators is presented. This recruits DC voltage the common source node switchingpair transistors as an indicator achieve best performance oscillator. The proposed has advantages not introducing any loading effect output node, ndependency from PVT changes. method simple applicable oscillator with topolo...

This paper presents equivalent forms of the Sylvester matrix equations. These equivalent forms allow us to use block linear methods for solving large Sylvester matrix equations. In each step of theses iterative methods we use global FOM or global GMRES algorithm for solving an auxiliary block matrix equations. Also, some numerical experiments for obtaining the numerical approximated solution of...

A fast vibration reduction optimization approach accelerated by the global proper orthogonal decomposition (POD) reduced-order model (ROM) is proposed, aiming at increasing efficiency of frequency response analysis and complex thin-walled shells. At offline stage, POD ROM adaptively updated using sample configurations generated CV (cross validation)–Voronoi sequence sampling method. In comparis...

It is well-known that the performance of POD and POD-DEIM methods depends on the selection of the snapshot locations. In this work, we consider the selections of the locations for POD and POD-DEIM snapshots for spatially semi-discretized linear or semi-linear parabolic PDEs. We present an approach that for a fixed number of snapshots the optimal locations may be selected such that the global di...
