The objective is to study fatigue failure of gears and bearings during processing of rebars and evaluate their performance under cyclic stresses. Mechanical vibration was measured on gears and bearings to determine efficiency and to avoid fatigue fai

Introduction Tetralogy of Fallot (TOF) occurs in 4 of every 10,000 live births and is the most common form of cyanotic congenital heart disease. Patients with repaired TOF (rTOF) require long-term and frequent monitoring for many complications that m

This paper presents the analysis of a new implementation for designing a downsampling multirate hybrid Continuous-time (CT)/discrete-time (DT) cascade ΣΔ modulator that saves silicon area and offers a reduction of power consumption. Since the hybri

In North of Santander, panela production is carried out in traditional burners, where bagasse is used as fuel. This rudimentary and artisanal form is inefficient in energy terms. For the present study, three burner samples were selected, determining

In this paper SIMSIDES-based (Simulink-based Sigma Delta Simulator) high level simulation of a 4th order Hybrid ΣΔ Modulator was carried out to find the performance requirements of several Analog Building Blocks (ABB). Once the requirements have be

This paper presents a new concept of multirate cascade ΣΔ modulators, in which the signal is downsampled across the cascade instead of being upsampled as done in conventional multirate architectures. This strategy is suited for hybrid continuous-ti

Transmission of HIV-1 with reduced susceptibility to antiretroviral drugs raises public health concerns. Through surveillance of drug-resistant HIV-1 in 603 treatment-naïve, recently diagnosed HIV-1-infected persons, we identified a distinct group o
