Combining horizontal ambient vibration components for H/V spectral ratio estimates

Liquefaction Hazard assessment using Horizontal-to-Vertical Spectral Ratio of Microtremor

In this paper, the spectral ratio of mmicrotremor, HSVR, is presented for estimating the liquefaction potential of layered soil in the coastal area of the Persian Gulf, which consists of a hard sandstone layer situated between two saturated sandy layers. The surface layer is thin, with a thickness between 2 and 5 meters. The purpose of this paper is to identify the relation between the liquefac...

Spectral Efficiency of Maximum Ratio Combining: Slow Fading

In this paper we derive closed-form expressions for the single-user capacity of Maximum Ratio Combiner (MRC) system system, taking into account the effect of imperfect channel estimation at the receiver. The channel considered is a slowly varying spatially independent flat Rayleigh fading channel. The complex channel estimate and the actual channel are modelled as jointly Gaussian random variab...

Random Generation of hv-Convex Polyominoes with Given Horizontal Projection

Combining Ability Estimates for Yield Some Traits in Tomato (Lycopersicon esculentum L.) by Line×Tester

     12 single crosses (F1) achieved by combining four testers and three commercial lines of tomato were evaluated for their response to water deficit stress and the combining ability of yield and some yield components. The layout was split plots according to randomized complete block design with three replications and three irrigation levels (FC, 60%FC and 40%FC). Crossing among lines and test...

Combining vibration test with finite element analysis for the fatigue life estimation of PBGA components

The study develops a methodology that combines the vibration failure test, finite element analysis (FEA), and theoretical formulation for the calculation of the electronic component’s fatigue life under vibration loading. A specially designed plastic ball grid array (PBGA) component with built-in daisy chain circuits is mounted on a printed wiring board (PWB) as the test vehicle for the vibrati...
