A method based on thermal bistability for ultralow-threshold microlaser optimization is demonstrated. When sweeping the pump laser frequency across a pump resonance, the dynamic thermal bistability slows down the power variation. The resulting line shape modification enables a real-time monitoring of the laser characteristic. We demonstrate this method for a functionalized microsphere exhibitin...

In recent years, thermal actuated flying height control has been implemented in Hard Disk Drives (HDD) to reduce the effect of flying height variations due to manufacturing tolerances or write current introduced pole tip protrusion (Fig. 1). A stable low flying height is necessary to achieve low bit error rates (BER) [1]. Thermal flying height control is used in a “static manner” in current dis...

With an increased focus on renewable power generation, dynamic thermal ratings of various equipment are being investigated to connect the new intermittent generation grid without needing replace existing infrastructure. Previous research is mainly focused a rating for overhead lines. End-of-line also restricted by limit. This paper combines model lines with transformer model, investigate impact...

An ab initio quantum-mechanical theoretical framework is presented to compute the thermal properties of molecular crystals. The present strategy combines dispersion-corrected density-functional-theory (DFT-D), harmonic phonon dispersion, quasi-harmonic approximation to the lattice dynamics for thermal expansion and thermodynamic functions, and quasi-static approximation for anisotropic thermo-e...

This paper presents a data-driven method for producing annual continuous dynamic rating of power transformers to serve the long-term planning purpose. Historically, research works on have been focused real-time/near-future system operations. There has lack oriented applications. Currently, most utility companies still rely static numbers when next few years. In response, this proposes novel and...

The aim of this paper is to present a novel phasor measurement unit (PMU) data-based cable temperature monitoring method with an intended application towards facilitating dynamic line rating. First part the presents estimate and track 3-phase segment. benefit that no additional sensors are required be placed along cable. based on algorithm which gives accurate resistance estimates for segments ...
