OBJECTIVE Current diagnostic assessment tools remain suboptimal in demonstrating complex morphology of congenital heart disease (CHD). This limitation has posed several challenges in preoperative planning, communication in medical practice, and medical education. This study aims to investigate the dimensional accuracy and the clinical value of 3D printed model of CHD in the above three areas. ...

The use of 4D simulations within the construction field is growing, however, its application when carrying out true collaborative planning has not yet been fully realised. It is postulated that 4D models are currently utilised as a planning review tool, rather than integral to the initial construction planning process and do not fully support multidisciplinary collaborative construction plannin...

In this paper, we provide a systematic study of the task of sensor planning for object search. The search agent’s knowledge of object location is encoded as a discrete probability density which is updated whenever a sensing action occurs. Each sensing action of the agent is defined by a viewpoint, a viewing direction, a field-of-view, and the application of a recognition algorithm. The formulat...

Virtual Reality based geographic information systems (VRGIS) are successfully employed today for real-time visualization in such diverse fields as urban planning, city planning, and architectural design. Today a VRGIS based software solution has to facilitate the interactive visualization of highresolution 3D terrain data over interand intranet. Due to advanced software technology and innovativ...

This paper provides a new approach to solve the motion planning problems of flying robots in uncertain 3D dynamic environments. The robots controlled by this method can adaptively choose the fast way to avoid collision without information about the shapes and trajectories of obstacles. Based on sphere coordinates the new method accomplishes collision avoidance of flying robots without any other...

Computing rectilinear shortest paths in two dimensions has been solved optimally using a number of different techniques. A variety of related problems have been solved, including minimizing the number of bends in the path, the total rectilinear distance, or some combination of both. However, solutions to the 3D versions of these problems are less common. We propose a solution to the 3D minimum-...

The aim of this study was to present a case series of the orthognathic treatment of facial asymmetry due to temporomandibular joint (TMJ) ankylosis and to characterize the current treatment modalities through a literature review. Four patients who presented with facial asymmetry due to TMJ ankylosis between 2010 and 2014 were included in this study. TMJ ankylosis was surgically treated before b...

Photodynamic therapy (PDT) dosimetric tools are crucial for treatment planning and noninvasive monitoring by means of fluorescence. Present approaches consider usually a 1D problem, a simple photochemical process, or a spatially homogeneous photosensitizer. In this work, a radially resolved superficial photosensitizer fluorescence and 3D photochemical time-dependent PDT model are presented. The...

CABot3, the third Cell Assembly roBot, is an agent implemented entirely in simulated neurons. It is situated in a virtual 3D environment and responds to commands from a user in that environment. It parses the user’s natural language commands to set goals, uses those goals to drive its planning system, views the environment, moves through it, and learns a spatial cognitive map of it. Some system...
