MEANS OF DYNAMIC DATA INTEGRATION IMPLEMENTATION VIA TOOLS OF EXISTING CAD SYSTEMS

dynamic coloring of graph

در این پایان نامه رنگ آمیزی دینامیکی یک گراف را بیان و مطالعه می کنیم. یک –kرنگ آمیزی سره ی رأسی گراف g را رنگ آمیزی دینامیکی می نامند اگر در همسایه های هر رأس v?v(g) با درجه ی حداقل 2، حداقل 2 رنگ متفاوت ظاهر شوند. کوچکترین عدد صحیح k، به طوری که g دارای –kرنگ آمیزی دینامیکی باشد را عدد رنگی دینامیکی g می نامند و آنرا با نماد ?_2 (g) نمایش می دهند. مونت گمری حدس زده است که تمام گراف های منتظم ...

Integration Method of Cad Systems

∗ Postdoctoral researcher and author of correspondence, Phone: +49 391-67-12-668, Email: [email protected]. ABSTRACT This paper presents the modification of a non-iterative algorithm for the component-oriented simulation of the dynamics of multibodies. Now the method can be implemented for the component-oriented simulation of the dynamics of CAD systems with redundant c...

Data Integration by means of Object Identification in Information Systems

Data integration is an important topic in the information age. Although structural aspects are widely investigated, there is a lack of research on semantic discrepancies between data sources. Data integration should be able to handle input errors such as erroneous data and misspellings. Also problems like domain and data type mismatch, of missing values and duplicated records need investigation...

Dynamic Query Scheduling in Data Integration Systems

Execution plans produced by traditional query optimizers for data integration queries may yield poor performance for several reasons. The cost estimates may be inaccurate, the memory available at run-time may be insufficient, or data delivery rate can be unpredictable. In this paper, we address the problem of unpredictable data arrival rate. We propose to dynamically schedule queries in order t...
