The structural properties of  high Tc superconductor by XRD, SEM and EDX, resistivity, critical electrical current density and oxygen content measurement have ben studied. The sample of  is prepared by solid state reaction, with two different thermal conditions. The XRD results have shown the formation of pure phase of . The oxygen content measurement for two samples by Iodometric titration giv...

Pele has been the most intense high-temperature hotspot on Io to be continuously active during the Galileo monitoring from 1996–2001. A suite of characteristics suggests that Pele is an active lava lake inside a volcanic depression. In 2000–2001, Pele was observed by two spacecraft, Cassini and Galileo. The Cassini observations revealed that Pele is variable in activity over timescales of minut...

We present an experimental proof of concept of scanning thermal nanoprobes that utilize the extreme thermal conductance of carbon nanotubes (CNTs) to channel heat between the probe and the sample. The integration of CNTs into scanning thermal microscopy (SThM) overcomes the main drawbacks of standard SThM probes, where the low thermal conductance of the apex SThM probe is the main limiting fact...

Abstract In machine tools, it is important to maintain accuracy against heat in the entire machining space. The reduction of thermal displacement achieved by measuring accurately and then clarify relationship between temperature change deformation creating prediction compensation model or applying countermeasure suppress deformation. To solve this issue, authors have developed methods measure t...

The development of an indirect measurement model for electro thermal furnace and its implementation in a reconfigurable architecture are the main issues of this article. The proposed measurement system is based on the system model, the principle of conservation of energy and the laws of thermodynamics are applied to build a model of the thermal system where the Kalman theory is applied for filt...

An apparatus has been developed to measure the thermal conductivity of ceramic coatings. Since the method uses an infrared microscope for temperature measurement, coatings as thin as 20 μm can, in principle, be measured using this technique. This steady-state, comparative measurement method uses the known thermal conductivity of the substrate material as the reference material for heat-flow mea...

The effect of measurement errors on adaptive and non-adaptive control charts has been occasionally considered by researchers throughout the years. However, that effect on the variable sample size and sampling interval (VSSI) control charts has not so far been investigated. In this paper, we evaluate the effect of measurement errors on the VSSI control charts. After a model development, the effe...
