We describe two experimental approaches to circumvent the problem of self-heating in IV measurements on small mesa samples of 2212-BSCCO. Simultaneous dc and temperature measurements have been performed, allowing corrections for heating to be made. Short pulse measurements have also been made, where the IV characteristics and the mesa temperature can be measured on a µs timescale enabling intri...

It is difficult to predict the heating time and power consumption associated with the self-heating process of lithium-ion batteries at low temperatures. A temperature-rise model considering the dynamic changes in battery temperature and state of charge is thus proposed. When this model is combined with the ampere-hour integral method, the quantitative relationship among the discharge rate, heat...

A predictive and adaptive heating controller, using artificial neural networks to allow the adaptation of the control model to the real conditions (climate, building characteristics, user's behaviour) is described. The choice of a predictive control strategy, combined with the nonlinear modelling of the building, the user's behaviour and the weather prediction, allows the NEUROBAT controller to...

近年,熱問題が主要な設計問題となってきている.エレク トロマイグレーション [1,2]などに代表される信頼性低下 要因やリーク電流は温度に強く依存し,温度上昇による リーク電力増大は発熱量をさらに増加させるためである. この問題を解決するために,チップ全体の熱解析やアー キテクチャレベル [3]から物理設計レベル [4]の熱指向設 計が産学界双方で注目されている. 微視的視点では.グローバル配線の自己発熱問題が集中 的に研究されてきた [5–11].配線抵抗によるエネルギー 消費が配線内部に熱を発生させ,それが温度上昇に繋が る現象が自己発熱効果である.配線の過熱により,(1)配 線の電気抵抗の増大による信号伝達速度の低下,(2)エレ クトロマイグレーションなどによる信頼性低下,が生じ る.グローバル配線での自己発熱問題は以下の理由によ り集中的に研究されてきた: (1)グローバル配...

This paper presents a self-folding method for multi-crease structures. The proposed method utilizes the symmetric breaking of a 3-layered two-dimensional sheet, where an inner contraction sheet induces shear force when heated, which directs the inclined folding direction. The fabrication technique developed enables distant placements of tiling patterns of the surfaces. The experimental result s...

We study the effect of active galactic nuclei (AGN) heating on the chemodynamical evolution of elliptical galaxies and their X-ray and optical properties using highresolution Λ-dominated cold dark matter cosmological simulations. Our model considers an AGN as being “active” when a convergent gas inflow condition exists within a galaxy’s nucleus; otherwise, the AGN is assumed to remain dormant. ...

Articular cartilage is a soft tissue showing inelastic properties. Under cyclic loading, inelastic materials may dissipate mechanical energy into heat. In knee cartilage, due to an intrinsic reduced heat convection related to its avascularity, a local temperature increase could be observed. This phenomenon is referred to as self-heating. As cells are sensitive to temperature variation, the ener...
