We investigate different approaches to integrating object recognition and planning in a tabletop manipulation domain with the set of objects used in the 2012 RoboCup@Work competition. Results of our preliminary experiments show that, with some approaches, close integration of perception and planning improves the quality of plans, as well as the computation times of feasible plans.

Patterns of land use and available transportation systems play a critical role in determining the economic vitality, livability, and sustainability of urban areas. Transportation interacts strongly with land use. For example, automobile-oriented development induces demand for more roads and parking (which in turn induces more automobile-oriented development), while compact, pedestrian-friendly ...

introduction: the complex geometry of breast and also lung and heart inhomogeneities near the planning target volume (ptv) result in perturbations in dose distribution. this problem can result in overdosage or underdosage in the match region of the three treatment fields. the purpose of this study is to create a homogeneous dose distribution in the match region between the supraclavicular and t...

Building information modeling (BIM) technologies use precise geometry and relevant data to enhance and improve the maintenance performance of facilities integrated with 3D object-oriented computer aided design (CAD). Although most owners agree on the potential benefits of integrating BIM technologies with facility management (FM), they must overcome many problems to plan and develop effective B...

This paper addresses three research issues for virtual heritage system, 3D modeling, 3D media asset database management, and interactive presentation through networks. We first show an overview of our virtual heritage system. Then, our approaches on each research issue are introduced. We develop 3D modeling environment using both of two emerging techniques, i.e., image-based 3D modeling and 3D ...

introduction: radiation therapy following breast conserving surgery is one of the most common procedures performed in any radiation oncology department. a tangential parallel-opposed pair is almost always the technique of choice for this purpose. this technique is often performed based on 3d treatment planning. the aim of this study was to compare 3d treatment planning for two different energie...

Introduction: Breast conserving surgery followed by adjuvant radiotherapy (RT) of the whole breast is accepted as the treatment of choice in early stage breast cancer. Due to breast irregularities, it is difficult to access homogenous dose distribution with conventional techniques. Currently, it is possible to use varied breast irradiation techniques, such as field- in-field (F...

Web-based three-dimensional Virtual Body Structures (W3D-VBS) is a next-generation immersive anatomical training system for teaching human anatomy over the Internet. It uses Visible Human data to dynamically explore, select, extract, visualize, manipulate, and stereoscopically palpate realistic virtual body structures with a haptic device. Tracking user’s progress through evaluation tools helps...

Models which embody brain design principles and mechanisms that subserve visual perception, cognition, emotion, and action have clarified how the brain can adapt in real time to changing environmental conditions. The brain’s ability to do this in a self-stabilizing fashion employs several different types of predictive mechanisms. The lack of a single such mechanism is clarified by accumulating ...

Model-based planning often presumes a static system model, while in a practice physical system may evolve or drift over time. This paper proposes the idea of pervasive model adaptation in a production system, where the model is dynamically updated using observation of production output. The core idea is the interplay between model adaptation and production planning. We seek plans which simultan...
