A Recurrent Neural Network Model for solving CCR Model in Data Envelopment Analysis

In this paper, we present a recurrent neural network model for solving CCR Model in Data Envelopment Analysis (DEA). The proposed neural network model is derived from an unconstrained minimization problem. In the theoretical aspect, it is shown that the proposed neural network is stable in the sense of Lyapunov and globally convergent to the optimal solution of CCR model. The proposed model has...

Review of Reduced Gravity Boiling Heat Transfer: European Research

The ˆrst section of this paper (overview on boiling heat transfer characteristics) is directed to those who are not specialists in the ˆeld of boiling heat transfer, in order to make them aware of the fundamental physical mechanisms, the advantages and the main problems of this technique. Next, some of the basic knowledge achieved on terrestrial boiling heat transfer is outlined, along with the...

Review of Reduced Gravity Boiling Heat Transfer: Japanese Research

To introduce the advance in the researches on boiling and two-phase ‰ow in reduced gravity ˆelds and the change in the situation surrounding them in Japan, a short review is focused on the individual research subjects, i.e., pool boiling, ‰ow boiling, and unheated two-phase ‰ow including their major topics. Representative results obtained so far are introduced. Future direction of researches on...

Highly subcooled pool boiling heat transfer at various gravity levels

A microscale heater array 2:7 mm 2:7 mm in size along with a video camera was used to provide subcooled pool boiling heat transfer measurements at gravity levels ranging from 1.8g to 10 g. The fluid was FC-72 at 1 atm and subcooled by nominally 36 C for all cases. A Terrier–Orion sounding rocket and the KC-135 aircraft were used to provide the microgravity and low-g environments, respectively. ...
