Organizations must quickly adapt their processes to understand the dynamic nature of modern business environments. As highlighted in literature, centralized governance supports decision-making and performance measurement technology companies. For this reason, a reliable system with an integrated data model that enables rapid collection transformation stored heterogeneous different sources is ne...

abstract t his paper explains bilateral trade patterns between south korea and thirteen opec member countries over the period 1980-2014 using a gravity model. the estimation results show that the gravity equation fits the data reasonably well. we confirmed the existence of long term relationships between the bilateral trade flows and the main components of gravity model - gdp, income (gdp per c...

ignoring two main characteristics of the concentration-response data, correlation between observations and presence of outliers, may lead to misleading results. therefore the special method should be considered. in this paper in to examine the effect of phenylephrine in rat corpus cavernosum, outlier robust nonlinear mixed estimation is used. in this study, eight different doses of phenylephrin...

A taxonomy of constraints for semistructured data models is presented. Several existing classes of constrains defined for different database models, such as relational and objectoriented, are analyzed in the context of semistructured data model. To capture dynamic aspects of consistency, data validity constraints are introduced. The most important subclass of data validity constraints, temporal...

This paper extends the semiparametric eÆcient treatment of panel data models pursued by Park and Simar (1994) and Park, Sickles, and Simar (1998, 2003) to a dynamic panel setting. We develop a semiparametric eÆcient estimator under minimal assumptions when the panel model contains a lagged dependent variable. We apply this new estimator to analyze the structure of demand between city pairs for ...

Most of researches on content descriptions and queries of temporal features only base on the thirteen kinds of temporal relationships defined by Allen, which are difficult to answer the queries of multimedia data that are built on temporal semantic abstraction. Based on the definition of Multimedia Object and Multimedia Data Unit (MDU), this paper focuses on the descriptive algorithm of general...
