in this work‎, ‎we formulate chatterjea contractions using graphs in metric spaces endowed with a graph ‎‎and‏ ‎‎‎‎investigate ‎the ‎existence‎ ‎of ‎fixed ‎points ‎for such mappings ‎under two different hypotheses‎. we also discuss the uniqueness of the fixed point. the given result is a generalization of chatterjea's fixed point theorem from metric spaces to metric spaces endowed with a g...

The most intuitive way of retrieving images is on the basis of domain concepts. However, this requires a mapping between the concepts and the content of the image. Such a mapping should be based on a proper visual guideline. We illustrate this with plant variety testing as an application for which such guidelines are available. The methods seem to have general applicability for every applicatio...

Cortical representations of muscles can be probed non‑invasively using transcranial magnetic stimulation (TMS) motor mapping. TMS mapping applied both in research and clinical settings to assess cortex reorganization under the influence various factors, clarify pathophysiological mechanisms system damage diseases, develop novel biomarkers this damage. The article discusses main methodological a...

Building applications over Linked Data often requires a mapping between the application model and the ontology underlying the source dataset in the Linked Data cloud. Explicitly formulating these mappings demands a comprehensive understanding of the underlying schemas (RDF ontologies) of the source and target datasets. This task can be supported by integrating the process of schema exploration ...

We develop a design methodology for mapping computer vision algorithms onto an FPGA through the use of coarse-grain reconfigurable dataflow graphs as a representation to guide the designer. We first describe a new dataflow modeling technique called homogeneous parameterized dataflow (HPDF), which effectively captures the structure of an important class of computer vision applications. This form...

Most agricultural crops cultivated in Brazil are highly nutrient demanding. Brazilian soils are generally acidic with low base saturation and available nutrients. Demand for fertilizer application has increased because the national agricultural sector expansion. To improve productivity without environmental impact, there is the need for the utilization of novel procedures and techniques to opti...
