Noise reduction by continuous addition of subchannel holograms
Applied Optics, 1975A new and convenient technique for reducing both speckle and coherent noise in holographic imagery is described with supporting experimental results. Its advantages and disadvantages have been mentioned in the context of other known techniques.

A Utility Perspective on Subchannel Analysis
Nuclear Technology, 1995Utility nuclear engineering organizations are among the primary end users of subchannel analysis technology. Typically there is only a limited involvement by utility staff in the actual development of subchannel software other than the addition of user convenience features such as editing routines and automated execution of multiple cases.

Numerical method improvement for a subchannel code
Kerntechnik, 2016Abstract Previous studies showed that the subchannel codes need most CPU time to solve the matrix formed by the conservation equations. Traditional matrix solving method such as Gaussian elimination method and Gaussian-Seidel iteration method cannot meet the requirement of the computational efficiency.

Multicarrier equalization by subchannel SINR maximization
The Second International Conference on Communications and Networking, 20101 In multicarrier (MC) communication receivers, the use of a time-domain equalizer (TEQ) mitigates inter-symbol and inter-carrier interferences by shortening the overall channel delay spread. Nevertheless, the TEQ-based MC-receiver structure does not result in optimal bit rate and if one wants to optimize the bit rate a nonlinear cost function has to ...

The investigation of thermal hydraulic performance, either operating-steady-state or accident-transient conditions of nuclear reactor core, constitutes the topic of the present chapter. Standard nuclear thermal hydraulic equations and models, i.e., adopted for accident analysis in primary circuit and discussed in different chapters of the book, are ...

RELAP5 investigation on subchannel flow instability
Kerntechnik, 2016Abstract Two-phase flow instability is a vitally important area of study for a large number of industrial systems. Density Wave Oscillation (DWO) is the most common type of flow instability caused by the change in flow rate or power in boiling systems.

The Japanese Utilities’ Expectations for Subchannel Analysis
Nuclear Technology, 1995Boiling water reactor (BWR) utilities in Japan began to consider the development of a mechanistic model to describe the critical heat transfer conditions in the BWR fuel subchannel. Such a mechanistic model will not only decrease the necessity of tests, but will also help by removing some overly conservative safety margins in thermal hydraulics.
