Object grasping is one of the fundamental tasks of personal robots. There are several approaches to this problem, some requiring a 3D model of the object. Saxena et al. [1] proposed a learning algorithm which does not require a 3D model; instead it identifies points on the object corresponding to good grasping locations based on computer vision. Our(More)
—Placing is a necessary skill for a personal robot to have in order to perform tasks such as arranging objects in a disorganized room. The object placements should not only be stable but also be in their semantically preferred placing areas and orientations. This is challenging because an environment can have a large variety of objects and placing areas(More)
We consider the problem of learning object arrangements in a 3D scene. The key idea here is to learn how objects relate to human poses based on their affordances, ease of use and reachability. In contrast to mod-eling object-object relationships, modeling human-object relationships scales linearly in the number of objects. We design appropriate density(More)
PURPOSE To investigate the variation in macular retinal thickness in otherwise normal young Asian myopic subjects by using optical coherence tomography (OCT). METHODS One hundred thirty ophthalmically normal men 19 to 24 years of age with myopia (spherical equivalent, -0.25 to -14.25 D) underwent examination of one randomly selected eye. Visual acuity,(More)
—The ability to place objects in an environment is an important skill for a personal robot. An object should not only be placed stably, but should also be placed in its preferred location/orientation. For instance, it is preferred that a plate be inserted vertically into the slot of a dish-rack as compared to being placed horizontally in it. Unstructured(More)
—The collection and prompt analysis of synchropha-sor measurements is a key step towards enabling the future smart power grid, in which grid management applications would be deployed to monitor and react intelligently to changing conditions. The potential exists to slash inefficiencies and to adaptively reconfigure the grid to take better advantage of(More)
PURPOSE A recent study identified single nucleotide polymorphisms (SNPs) within the IL-1 gene cluster at chromosomal locus 2q13 that were associated with reduced risk for primary open-angle glaucoma (POAG) in whites. The purpose of this study was to investigate the association between IL-1 SNPs and glaucoma in Chinese patients with either POAG or(More)
PURPOSE This study evaluated the use of combined bevacizumab with 5-fluorouracil (5-FU) on postoperative scarring and bleb survival after experimental glaucoma filtration surgery in comparison to the agents alone. METHODS Filtration surgery was performed on 26 female New Zealand White rabbits. The rabbits were allocated to one of four treatments: 5-FU(More)
