The physically-based distributed hydrological models play an important role in watershed hydrology. Physical simulation of flow routing depends largely on the field distribution of flow velocity.Terrain analysis studies have previously focused more on the delineation of geomorphologic structures rather than the description of hydraulic factors. As affected by multiple uncertain factors includin...

A summary of research in urban feature extraction being conducted under a MURI (multi-disciplinary research initiative) program sponsored by the U.S. Army Research Office is provided. Most of the paper focuses on extraction of rectilinear building models. Feature extraction from aerial images is difficult due to problems of segmentation, 3-D inference and shape description. A system for buildin...

The exponential degree distribution has been found in many real world complex networks, based on which, the random growing process has been introduced to analyze the formation principle of such kind of networks. Inspired from the nonequilibrium network theory, we construct the network according to two mechanisms: growing and adjacent random attachment. By using the Kolmogorov-Smirnov Test (KST)...

Mapping in the GPS-denied environment is an important and challenging task in the field of robotics. In the large environment, mapping can be significantly accelerated by multiple robots exploring different parts of the environment. Accordingly, a key problem is how to integrate these local maps built by different robots into a single global map. In this paper, we propose an approach for simult...

The Smart Grid promises to provide better monitoring and control by incorporating the communication network over the power network. We investigate the monitoring and control of distribution sub-Grids, for example to a local area in a city. We propose a communication architecture to be deployed into a real local area of the sub-Grid to provide a test bed for supporting real-time data and predict...

Power grid outages cause huge economical and societal costs. Disruptions in the power distribution grid are responsible for a significant fraction of electric power unavailability to customers. The impact of extreme weather conditions, continuously increasing demand, and the over-ageing of assets in the grid, deteriorates the safety of electric power delivery in the near future. It is this depe...

This paper presents a 3D online path planning algorithm for a 6DOF Rotary Unmanned Aerial Vehicle (RUAV) operating in a cluttered environment using a Gaussian Process (GP) occupancy map. Traditional grid-based occupancy maps suffer from the curse of dimensionality for platforms that operate in a high dimensional configuration space. In addition, the grid resolutions, shapes and orientations lim...

The e-Government Grid Service Model in Indonesia is an adjustments based on the framework of existing e-Government and also the form of government in the country. Grid-based services for interoperability could be a solution for resource sharing and interoperability of e-Government systems. In previous study, we designed and simulated the topology of Indonesian e-Government Grid services based o...

Grid cells in the entorhinal cortex are generally considered to be a central part of a path integration system supporting the construction of a cognitive map of the environment in the brain. Guided by this hypothesis existing computational models of grid cells provide a wide range of possible mechanisms to explain grid cell activity in this specific context. Here we present a complementary grid...
