We emphasize that interactive evolutionary computation (IEC) can be used not only to optimize a target system based on an IEC user’s subjective evaluations but also to analyze the characteristics of the IEC user. We introduce four research works as concrete examples of this new research direction: measuring a perceived range for emotional expressions, finding unknown auditory knowledge through ...

co-channel interference is a major factor in limiting the capacity and link quality in cellular communications. as the co-channel interference is modeled by lognormal distribution, sum of the co-channel interferences of neighboring cells is represented by the sum of lognormal random variables (rvs) which has no closed-form expression. assuming independent, identically distributed (iid) rvs, the...

An approach for processing sonar signals with the ultimate goal of ocean bottom sediment classification and underwater buried target classification is presented in this paper. Work reported for sediment classification is based on sonar data collected by one of the AN/AQS-20’s sonars. Synthetic data, simulating data acquired by parametric sonar, is employed for target classification. The techniq...

The stepped micro-mirror imaging Fourier transform spectrometer (SIFTS) has the advantages of high throughput, compactness, and stability. However, systematic errors in interference core SIFTS have a significant impact on interferogram reconstructed spectrum. In order to reduce influence errors, transfer error model is established, an spectrum calibration method presented, which combines least ...

As an important basis for its structural optimization design, the heat transfer performance has a key influence on reliability of automobile brake. Based finite element method, transient disc brake is analyzed under condition dynamic convection coefficient. According to simulation results, CCD (Central Composite Design) sampling scheme used transform variable and target into multiple design poi...

Standard tracking filters perform target detection process by comparing the sensor output signal with a predefined threshold. However, selecting the detection threshold is of great importance and a wrongly selected threshold causes two major problems. The first problem occurs when the selected threshold is too low which results in increased false alarm rate. The second problem arises when the s...

In this article, an efficient Z-transform-based finite-difference time-domain (Z-FDTD) is developed to implement and analyze electromagnetic scatterings in the 3D biaxial anisotropy. terms of Z-transform technique, we first discuss conversion relationship between time- or frequency-domain derivative operators corresponding Z-domain operator, then build up iteration from electric flux D converte...
