فعالیت های نگهداری و تعمیرات اطلاعاتی را تولید می کند که می تواند در تعیین زمان های بیکاری و ارایه یک برنامه زمان بندی شده یا تعیین هشدارهای خرابی به پرسنل نگهداری و تعمیرات کمک کند. وقتی که مقدار داده های تولید شده زیاد باشند، فهم بین متغیرها بسیار مشکل می شوند. این پایان نامه به کاربردی از داده کاوی برای کاوش پایگاه های داده چندبعدی در حوزه نگهداری و تعمیرات، برای پیدا کردن خرابی هایی که موجب...

Data Persistency Solution for LHCb

The GAUDI software architecture, designed in the context of the LHCb experiment, maintains separate and distinct descriptions of the transient and persistent representations of the data objects. One of the motivations for this approach has been the requirement for a multitechnology persistency solution such that the best-adapted technology can be used for each category of data: raw event data, ...

SPARQL Query Optimization for Structural Indexed RDF Data

Resource description framework, RDF, is a standard language model for representing semantic data. As the concept of Semantic Web becomes more viable, the ability to retrieve and exchange semantic data will become increasingly more important. Efficient management of RDF data is one of the key research issues in Semantic Web; consequently, many RDF management systems have been proposed with data ...

Type-Indexed Data Types

A polytypic function is a function that can be instantiated on many data types to obtain data type speci c functionality. Examples of polytypic functions are the functions that can be derived in Haskell, such as show , read , and ( ). More advanced examples are functions for digital searching, pattern matching, uni cation, rewriting, and structure editing. For each of these problems, we not onl...
