Proposed Hybrid Sparse Adaptive Algorithms for System Identification
Al-Khawarizmi Engineering Journal, 2017 For sparse system identification,recent suggested algorithms are -norm Least Mean Square ( -LMS), Zero-Attracting LMS (ZA-LMS), Reweighted Zero-Attracting LMS (RZA-LMS), and p-norm LMS (p-LMS) algorithms, that have modified the cost function of the ...

Long-term taxonomic and functional stability of the gut microbiome from human fecal samples
Scientific Reports, 2023 Appropriate storage of fecal samples is a critical step for unbiased analysis in human microbiome studies. The purpose of this study was to evaluate the stability of the fecal microbial community for up to 18 months. Ten healthy volunteers provided fecal

Effect of Mixing Condition on Rheological Behavior of Epoxy-Clay Nanocomposites [PDF]
علوم و تکنولوژی پلیمر, 2012 The effect of mixing on rheological behavior of 6% wt epoxy-clay nanocomposites was studied. The mixing processes were carried out by low shear mixer, homogenizer and ultrasonic and combination of different mixing techniques at medium and maximum power ...

Dynamics of spinning test particles in Kerr spacetime [PDF]
, 2002 We investigate the dynamics of relativistic spinning test particles in the spacetime of a rotating black hole using the Papapetrou equations. We use the method of Lyapunov exponents to determine whether the orbits exhibit sensitive dependence on initial ...

The role of observability in futures markets [PDF]
, 2006 Allaz (1992) and Allaz and Vila (1993) show that in an oligopolistic industry the introduction of a futures market that operates prior to the spot market induces more competitive outcomes. Hughes and Kao (1997) show that this result presumes that firms’
