THEORY AND FUNDAMENTALS Temperature measurement can be divided into two categories: contact and noncontact. Contact thermocouples, RTDs, and thermometers are the most prevalent in temperature measurement applications. They must contact the target as they measure their own temperature and they are relatively slow responding, but they are inexpensive. Noncontact temperature sensors measure IR ene...

Abstract This paper reports an enhancement of the nonvolatile memory characteristics GaN/AlN resonant tunnelling diodes (RTDs) by reducing crystal defects in quantum well structure. Pit-shaped are strongly suppressed when pure N 2 , instead a /H mixture, is used as carrier gas and trimethylindium introduced surfactant for metalorganic vapor phase epitaxy In addition, density dislocations lowere...

Maximum power point tracker (MPPT) methods work to maximize the output of a PV system under changes in meteorological conditions. The performance these depends on complexity algorithm and number used variable inputs for obtaining MPP value. Moreover, they oscillate around steady-state operations, causing waste loss. do not perfectly running partial shading Therefore, this paper proposes modific...

A model for analyzing dynamic large-signal characteristics of double-barrier resonant-tunneling diodes (RTDs) is presented. The based on the analysis dynamical trajectories in phase space, defined by RTD bias and electron density quantum well. We show that an accurate can be reformulated approximate way, relying only a directly measurable DC I–V curve few other parameters, which could easily es...

This paper presents the ProMARTES toolkit for profiling, modeling and performance analysis of component-based real-time distributed systems (CB-RTDS). The ProMARTES toolkit features multiple benefits: (a) cycle-accurate profiling of individual components and automated generation of MARTEcompatible SW component performance models, (b) guided composition of a system architecture from available SW...

A novel type of millimeter/submillimeter wave sampler based on resonant tunneling diodes (RTDs) was proposed, and its operation was confirmed by circuit simulation. It consists of an RTD pulse generator and an RTD detector. Owing to the fuse-like nonlinear I-V curve, highly sensitive sampling can be obtained. We also found that the effects of nonideality in the I-V curve of the RTD can be corre...

In this paper, heterojunction nanowires of Ni-Se are fabricated via template-assisted electrodeposition process. Nanowires are characterized by scanning electron microscopy (SEM), Energy dispersive X-Ray Spectroscopy (EDS), X-ray diffractometry and electrical transport studies. SEM photographs reveal the uniform and dense growth of Ni-Se nanowires. X-ray diffraction pattern shows the crystallin...

This paper compares two deconvolution methodologies used to estimate residence time distributions (RTD) in industrial closed-circuit ball mills. Parametric and non-parametric techniques were evaluated. Both allowed for direct RTD estimates from inlet outlet tracer measurements the mills, with no need mass balances nor assumptions correct effect of recirculation grinding circuits. Measurements c...
