T h ree-dimensional (3D) s ha p e models have recentl y been used in various fields including machine designing, internet mall, and medical a pp lication. Therefore, efficient management and reuse of 3D sha p e models is becoming im p ortant with research on object searching of 3D sha p e models. 3D sha p e model searching requires taking into consideration rotation, scaling, and translation of models. This p a p er p ro p oses a method to search 3D objects to include and account for the above conditions. The p ro p osed method acquires 2D range images b y rendering a 3D object from man y view p oints, and discretel y a pp roximating two of the three degrees of rotational freedom b y a finite number of view p oints. Using the p hase correlation method on the range image one can estimate the rotation around one axis, include scaling and translation, and com p are the similarities between the in p ut with models in a dictionar y . Ex p erimental results show that whether models match or not match can be distinguished even when the su pp osed view p oints are limited to a finite number.

Fluorescent substances are used in a wide range of applications, and the method that effectively design molecules having desirable absorption and emission wavelength is required. In this study, we used borondipyrromethene (BODIPY) compounds as a case study, and constructed high precision wavelength prediction model using ensemble learning. Prediction accuracy improved in stacking model using RDKit descriptors and Morgan fingerprint. The variables related to the molecular skeleton and the conjugation length were shown to be important. We also proposed an applicability domain (AD) estimation model that directly use the descriptors based on Tanimoto distance. The performance of the AD models was shown better than the OCSVM-based model. Using our proposed stacking model and AD model, newly generated compounds were screened and we obtained 602 compounds which were estimated inside the AD in both absorption wavelength and emission wavelength.
