In this paper, we present an application of symbolic data processing for the design of virtual character’s smiling facial expressions. A collected database of virtual character’s smiles directly created by users has been explored using symbolic data analysis methods. An unsupervised analysis has enabled us to identify the morphological and dynamic characteristics of different types of smiles as well...
Compound comparison is an important task for computational chemistry. By the comparison reulsts, potential inhibitors can be found and then used for the following experiments. The time complexity of a pairwise compound comparison is O(n2), where n is the maximal length of compounds. In general, the compound length is small, and the cost of computation time is short. However, more and more compounds...
Performance of Superconducting Submillimeter-Wave Limb Emission Sounder (SMILES) onboard International Space Station was discussed from the analysis of random errors of Chlorine monoxide (ClO) in the stratosphere and mesosphere. Some lessons learned from the SMILES operation in space are discussed.
The Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) observes vertical profiles of atmospheric minor constituents related with stratospheric and mesospheric chemical processes. The retrieved profiles contain some error originated from the response characteristics of radio spectrometers of the SMILES instrument. The on-orbit properties are necessary to be characterized and be modeled,...
The Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) observes O3 and other minor chemical species in the stratosphere and mesosphere. Limb observation of SMILES is sensitive to the quality of the tangent altitude retrieval. To obtain better retrieval result, knowledge of initial tangent height and antenna pattern should be as precise and accurate as possible. It was concluded that...
Encouraged by recent legislations all over the world, aimed to protect human health and environment, in silico techniques have proved their ability to assess the toxicity of chemicals. However, they act often like a black-box, without giving a clear contribution to the scientific insight; such over-optimized methods may be beyond understanding, behaving more like competitors of human experts' knowledge,...
Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) is a sensor for atmospheric observation at 640 GHz from the International Space Station. Since the launch in Sep. 2009, SMILES has been showing the excellent observation performance. The results of SMILES development are summarized.
Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) has been operated on orbit since late September 2009. The on-orbit performance of the SMILES submillimeter receiver satisfied the specifications and demonstrated a high capability of superconducting technology for atmospheric science by providing an invaluable low-noise atmospheric limb-emission spectral data in 640-GHz band. The accuracy...
In this paper we compare two methods for toxicity prediction: a novel method called a neural grammar network (NGN) and a more conventional Quantitative Structure Activity Relation (QSAR) approach based on a feed forward artificial neural network (ANN). Focusing each round of training and prediction on target organisms and specific organ systems sufficiently narrows down the parameters for us to do...
This paper describes the design, manufacturing and performance test results of a submillimeter antenna (ANT) of SMILES at 0.64THz. The design of ANT is aiming at achieving high beam efficiency, low side lobe levels and a high thermal stability (Noguchi, 2003)(Noguchi et al., 2004). In this paper, a manufactured engineering flight model (EFM) of ANT and its measured performance, such as surface errors...
