Many tasks in robotics and automation require a cyclic exchange of energy between a machine and its envi ronment Since most environments are under actu ated that is there are more objects to be manip ulated than actuated degrees of freedom with which to manipulate them the exchange must be punctuated by intermittent repeated contacts In this paper we develop the appropriate theoretical setting ...

Sketching consists of a widely practised activity during early design phases of product in general and for user interface development in particular in order to convey informal specifications of the interface before actually implementing it. It is quite interesting to observe that designers as well as end users have abilities to sketch parts or whole of the final user interface they want, while ...

Ground calibration targets (GCTs) play a vital role in atmospheric correction of satellite sensor data in the optical region, but selecting suitable targets is a subjective and timeconsuming task. This paper describes a method to automatically select suitable GCTs, using a combination of remotely sensed multispectral and topographic data. Desirable characteristics for GCTs sites were identified...

This paper looks at a data set, called the SHARE 2010 collect, that has been designed to analyze the various impacts of illumination change on materials. Similar fabric materials were placed on different backgrounds where spectral signatures were analyzed to determined impacts of background adjacency. Hyperspectral, multispectral, and LiDAR modalities were used to image the panels in the above ...

The paper presents an algorithm for deformable image registration based on point features extracted from input images using the Harris corner detector. The correspondence between the points extracted from the different images is established using RANdom SAmple Consensus (RANSAC) method with the affine and perspective global transformation used to model the deformations. The initial corresponden...

Automatic program execution control is a demanding tool for heteroge neous environments due to the variable availability of processors and network band width Issues such as load distribution have to be re analyzed since strategies developed for homogeneous machines fail to optimize the computation time in heterogeneous net works The nal user should not be involved in deciding which machines sho...

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...

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...

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...
