It is applied to the development of an accurate and fast approximation of an atmospheric long wave radiation parameterization for the NCAR Community Atmospheric Model, which is the most time consuming component of model physics. The developed neural network emulation is two orders of magnitude, 50-80 times, faster than the original parameterization. A comparison of the parallel 10-year climate simulations performed with the original parameterization and its neural network emulations, confirmed that these simulations produce almost identical results. The obtained results show the conceptual and practical possibility of an efficient synergetic combination of deterministic and statistical learning components within an atmospheric climate or forecast model.","PeriodicalId":102405,"journal":{"name":"2004 IEEE International Conference onComputational Intelligence for Measurement Systems and Applications, 2004.

This method can be applied in the drug development process to verify the lead compounds of the high throughput screening with cell-based assays and there with reducing animal experiments. This verification is also called high content screening. To be able to detect and to evaluate action potentials, which mainly represent the electrical cell activity, neurons are cultured on a silicon sensor chip with integrated electronics and a multielectrode array (MEA). Due to the high parallelism of the measurement efficient and flexible algorithms are needed to assess and to classify the acquired data in real time. A system, consisting of a field programmable gate array (FPGA) and a digital signal processor (DSP) provide the required implementation platform. Filtering based on the discrete wavelet transform removes superimposed noise and low frequency disturbances from the neural signal. This analysis offers also a method to compute an adaptive threshold, which is essential for the detection process. Subsequently the measured data is classified to provide the user with a feedback of the experiment. First promising evaluation results from simulations and proof of concept hardware implementations can be presented.","PeriodicalId":102405,"journal":{"name":"2004 IEEE International Conference onComputational Intelligence for Measurement Systems and Applications, 2004.

This is done by varying the device specification parameters with respect to set of predefined tests and determining where the part passes or fails. The key to this process is discovering the single trip (fig. 1. pass/fail) point as accurately as possible. However, this approach cannot guarantee the robustness of device performance variation vs specification based on only a single trip point and single test analysis. This means device could still violate the specification while passing all characterization tests. In this paper, we propose a novel multiple trip point characterization concept to overcome the constraint of single trip point concept in device characterization phase. In addition, we use computational intelligence techniques to further manipulate these sets of multiple trip point values and tests based on semiconductor ATE, such that characterization trip point values with respect to different tests can be learned by neural network and fuzzy system, then performing classification task of worst case variation of device's performance vs specification. At last, the final worst-case variation can be further detected by genetic algorithm. Our experimental results demonstrate an excellent design parameter variation analysis in device characterization phase, as well as detection of a set of worst-case tests that can provoke the worst-case variation, while traditional approach was not capable of detecting them.","PeriodicalId":102405,"journal":{"name":"2004 IEEE International Conference onComputational Intelligence for Measurement Systems and Applications, 2004.

Only few attempts of partial/full automated systems based on image-processing systems are present in literature and they are still at prototype stage. This paper presents a methodology to achieve an automated detection and classification of leucocytes by microscope color images. The proposed system firstly individuates in the blood image the leucocytes from the others blood cells, then it extracts morphological indexes and finally it classifies the leucocytes by a neural classifier in Basophil, Eosinophil, Lymphocyte, Monocyte and Neutrophil.","PeriodicalId":102405,"journal":{"name":"2004 IEEE International Conference onComputational Intelligence for Measurement Systems and Applications, 2004.
