The paper describes an approach to reason ing about actions and plan generation within the framework of description logics From an epistemological viewpoint our approach is based on the formalization of actions given by dynamic logics but we exploit their corre spondence with description logics to turn the formalization into an actual implementation In particular we are able to carefully weaken...

An expert system developed for use with geologic materials (minerals) has been modified to more generally analyze spectra of all types of materials, including manmade materials, military targets, and background. The methodology requires reflectance spectra, but can also be extended to emissive measurements in the mid-wave infrared (MWIR) and long-wave infrared (LWIR). The spectra of known mater...

Guangxi Province is one of the regions more serious desertification. This paper using ENVI image processing system, according to remote sensing image interpretation target mark and image spectral characteristics, found remote sensing interpretation model of the background information of forest, shrub and grass, agricultural land, surface water, towns, roads from TM and ETM data from 1988 to 200...

A specific task of distributed and parallel Information Systems is workflow management. In particular, workflow management systems execute business processes that run on top of distributed and parallel Information Systems. Parallelism is due to performance requirements and involves data and applications that are spread across a heterogeneous, distributed computing environment. Heterogeneity and...

'Dynamic hypertext ' is hypertext which is automatically generated at the point of need. A number of NLG systems have now been developed to operate within a hypertext environment; and now that these systems are becoming widely available on the World Wide Web, it is useful to take stock of how well-equipped NLG technology is to work in this new domain. A generation system in a hypertext environm...

It is an important way that some remote sensing images of different spatial and spectral resolutions are fused to satisfy the requirement of general application. In order to achieve a good fusion result, low spatial spectral images should be resampled. At present, nearest neighbor resampling is often adopted which has some effects on the precision of new image. In this paper, an image fusion me...

Space-based robotic systems for diagnosis, repair and assembly of systems will require new techniques of planning and manipulation to accomplish these complex tasks. ' results of work in assembly task representation, discrete-ohd synthesis which provide a design environment for flexible assembly systems in manufacturing applications, and which extend to planning-of manipulation operations in un...

A simple determination method of diphenyl (DP) and o-phenylphenol (OPP) in agricultural products by GC/MS was examined. DP and OPP were extracted with ethyl acetate in the presence of anh. sodium sulfate. After addition of n-butanol, the extract solution was concentrated. Clean-up was achieved by shaking with graphitized bulk carbon (Supelclean ENVI-Carb). Addition of polyethylene glycol sharpe...

A multiresidue analysis of pesticides in tea using supercritical fluid extraction (SFE) and GC-MS was developed. The preprocessing using SFE shortened the total analysis time. The SFE extract contained less matrices than the extract obtained with organic solvents. However, these matrices disturbed instrumental analysis. So, the extract was cleaned up with ENVI™-Carb/NH2 and InertSep™ SI cartrid...
