This paper describes a contextual classification approach to classify complex forest change classes. Multi temporal forest change classifications are performed comparing the 1989 baseline for the Kyoto definition of ARD (Afforestation, Reforestation and Deforestation) with the status in 2000 for test territories in Siberia with extensive ground truth information from forest inventory. The diffe...

This work summarizes a novel approach for discrete terrain model construction and algorithms utilizing the terrain and road network data. The models and algorithms are baseline of SymSG Border Tactics constructive simulator focusing on border control operations performed by Border Guard forces involving local population, perpetrators and other actors. Developed simulation algorithms include sim...

the congestion pricing has been discussed as a practical tool for traffic management on urban transport networks. the traffic congestion is defined as an external diseconomy on the network in transport economics. it has been proposed that the congestion pricing would be used to reduce the traffic on the network. this paper investigates the cordon-based second-best congestion-pricing problems on...

this paper deals with leader-following and leaderless consensus problems of high-order multi-input/multi-output (mimo) multi-agent systems with unknown nonlinear dynamics in the presence of uncertain external disturbances. the agents may have different dynamics and communicate together under a directed graph. a distributed adaptive method is designed for both cases. the structures of the contro...

Management of bottomland hardwood sites requires adequate access to support forest operations. A study conducted in a bottomland forest in central Georgia has evaluated the effect of forest road design on sediment movement and water quality. Five years of measurement indicate that a conventional crowned road design is a net sir& for sediment, primarily due to settling in ditches. An alternative...

The road network design problem is to optimize the road network by selecting paths to improve or adding paths in the existing road network, under certain constraints, e.g., the weighted sum of modifying costs. Since its multi-objective nature, the road network design problem is often challenging for designers. Empirically, the smaller diameter a road network has, the more connected and efficien...

The prediction of travel time is challenging given the sparseness of real-time traffic data and the uncertainty of travel, because it is influenced by multiple factors on the congested urban road networks. In our paper, we propose a three-layer neural network from big probe vehicles data incorporating multi-factors to estimate travel time. The procedure includes the following three steps. First...

This paper focuses on an interdisciplinary approach using Geoinformation Science and Technology, Operations Research and Forest Science to overcome the limitations of the traditional forest road planning process. A pilot study shows that combining Geoinformation Science and Technology and Operations Research supports forest road planning. The first research objective solved in the project is th...
