Using a multiple response optimization approach to optimize the coefficient of performance

Applied Thermal Engineering, 2016
Abstract Response surface methodology was employed to optimize the efficiency of a refrigeration cycle demonstration unit using a multiresponse optimization approach. Statistically designed experiments were conducted to simultaneously minimize energy consumption and maximize the refrigeration effect of a compression refrigeration cycle.

Optimal order statistic filters with coefficient censoring

ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003
Order statistic (OS) filters are noted for their robust properties for smoothing or estimating signals immersed in noise. The effect of coefficient censoring on the smoothing performance of OS filters is considered. Coefficient censoring can be effected either by adding zero coefficients to an existing filter, or by computing the optimal (MSE) censored

Portfolio Optimization with Interval Coefficients

2014
In this chapter, we discuss portfolio optimization models with interval coefficients, where the expected return, risk and liquidity of assets are treated as interval numbers. In addition, some realistic constraints such as number of assets held in the portfolio and the maximal and minimal fractions of the capital allocated to the various assets are ...

Steganography using Cuckoo Optimized Wavelet Coefficients

Proceedings of the Third International Symposium on Women in Computing and Informatics, 2015
Secret data hiding has become center of information security research with the enormous growth of the internet. Many researchers are actively working towards increasing the capacity of hidden content, i.e., hiding bigger data/message in a cover without being perceivable.

Manifold optimization for nonnegative coefficient logistic regression

2016 International Joint Conference on Neural Networks (IJCNN), 2016
A novel estimation algorithm is introduced for logistic regression model with nonnegative coefficients constraints. The basic idea is to decompose the model parameters as a vector of convex coefficients (the multinomial manifold) and a scaling parameter, which are then optimized alternatively based on the maximum likelihood cost function. The first and

Randomized Polar Subcodes With Optimized Error Coefficient

IEEE Transactions on Communications, 2020
A method for construction of polar subcodes with reduced error coefficient is presented. The proposed approach relies on explicit enumeration of low-weight non-zero codewords in a polar code, and construction of dynamic freezing constraints which define a subcode not containing most of these codewords.
