Metamodel Transformation of Data Models Position Paper

This paper studies syntax and semantics of the Entity-Relationship (ER) and Relational data model and their transformation. The ER model may be regarded as a platform independent model and the Relational model as a prototypical platform specific model. The paper studies the transformation between these models and proposes to express that transformation again as a model.

Structures in Bc N Ruijsenaars-schneider Models

We construct the classical r-matrix structure for the Lax formulation of BC N Ruijsenaars-Schneider systems proposed in [18]. The r-matrix structure takes a quadratic form similar to the A N Ruijsenaars-Schneider Poisson bracket behavior, although the dy-namical dependence is more complicated. Commuting Hamiltonians stemming from the BC N Ruijsenaars-Schneider Lax matrix are shown to be linear ...

A Method for Protecting Access Pattern in Outsourced Data

Protecting the information access pattern, which means preventing the disclosure of data and structural details of databases, is very important in working with data, especially in the cases of outsourced databases and databases with Internet access. The protection of the information access pattern indicates that mere data confidentiality is not sufficient and the privacy of queries and accesses...

the clustering and classification data mining techniques in insurance fraud detection:the case of iranian car insurance

با توجه به گسترش روز افزون تقلب در حوزه بیمه به خصوص در بخش بیمه اتومبیل و تبعات منفی آن برای شرکت های بیمه، به کارگیری روش های مناسب و کارآمد به منظور شناسایی و کشف تقلب در این حوزه امری ضروری است. درک الگوی موجود در داده های مربوط به مطالبات گزارش شده گذشته می تواند در کشف واقعی یا غیرواقعی بودن ادعای خسارت، مفید باشد. یکی از متداول ترین و پرکاربردترین راه های کشف الگوی داده ها استفاده از ر...
