The AQUA Data Model and Algebra
نویسندگان
چکیده
This paper describes a new object-oriented model and query algebra that will be used as an input language for the query optimizers that are being built as a part of the EREQ project. The model adopts a uniform view of objects and values and separates syntactic, semantic, and implementation concerns. The algebra addresses issues of type-deened equality and duplicate elimination as well as extensions to bulk types other than sets.

Modeling of platinum leaching kinetics in aqua-regia solutions using the Elovich equation
Platinum extraction from different secondary sources has been experimentally tested by many researchers. In this article, dissolution of platinum in aqua-regia solution from two types of spent catalysts (reforming and nitric acid production) was kinetically studied. A variety of kinetic models for heterogeneous solid-liquid reactions, including homogeneous diffusion model, shrinking core model,...
متن کاملOrdered Types in the AQUA Data Model
We present a query algebra that supports ordering among the data ele ments Order is de ned as a relationship between various data elements of an instance This relationship can be a total or partial order among the elements or among equivalence classes where each equivalence class consists of one or more elements In terms of data structures ordered types can be viewed as graphs trees or lists La...
متن کاملEvaluation of Aqua Crop Computer Model in the Potato Under Irrigation Management of Continuity Plan of Jiroft Region, Kerman, Iran
The agricultural regions are running into difficulties, which are restrictive availability of water, successive appearing draughts, and overuse of ground water resources for supplemental water requirements. As a sample which is got from the farm is sent to the laboratory for testing and the laboratory works need devices. Hence, conducting farm experiments are expensive and time consuming to opt...

متن کاملInvestigating the RegCM model ability in simulation of summer Khorasan dust
The Great Khorasan in northeast Iran has a variety of surface structures and plains and high peaks, but due to its vicinity to the deserts of Afghanistan and Turkmenistan, it is affected by dust all the time, especially in summer. The purpose of this study was to simulate summer dust in this region by RegCM model. For this purpose, during the period 2000 to 2017, three extreme dust events were ...
