—This paper presents a process model to manage highly variable spatio – temporal processes of the real world. Processes highly correlate with signal transmission. So, the management of such processes raises new signal manipulation issues. The issues are process progressions and interactions between temporal and spatio – temporal, spatial and spatio –(More)
Integration of WorldView-2 satellite image with small footprint airborne LiDAR data for estimation of tree carbon at species level has been investigated in tropical forests of Nepal. This research aims to quantify and map carbon stock for dominant tree species in Chitwan district of central Nepal. Object based image analysis and supervised nearest neighbor(More)
This paper addresses to development of the conceptual modeling phase of spatio-temporal phenomena. It is necessary to develop new techniques to accommodate the peculiarities of the combined spatial and temporal information that take their outset in existing techniques and minimally extend them. Interpretation of real world phenomena in a process perspective(More)
In order to supply live, accurate, reliable position information of mobil station during city traffic inducement system, through exposition on vehicle orientation navigation system theory in intelligent transportation system (ITS), make key research on working theory and data fusion of GPS/DR make-up orientation technology such as Particle Filter (PF)(More)
Traditional geographical information systems hold only a single state of the ‘real world’. However, geographic phenomena have not only static but dynamic characteristics. The work described in this paper explicit the development of the conceptual modeling phase of geographic phenomena in a dynamic perspective. This modeling approach highly(More)
Spatio-Temporal Process Model (STPM) is novel designed process oriented architecture which has enormous capacities in modeling dynamic aspect of the spatio-temporal phenomena. This model highly correlates with concurrent processing and signal transmission by associating syntax and semantics of π-calculus. We discuss the further development of this(More)

A new charging scheme is presented for the electronic road pricing (ERP) system, which would be based on distance traveled on different roads determined by integrated GPS positioning and digital road network database in GIS. System architecture consists of in-vehicle unit (IU) and the control center system (CCS) for the scheme is described. Technical(More)
The traditional P-median selecting location model of logistics is based on the statistical static model. These traditional mathematical models often don't consider topography, transport conditions, slop etc. The distance between two nodes is often assumed for the straight line in this model, so the analytical result usually can not be used as a warehouse in(More)
