ROL is a deductive object base language being developed at the University of Regina. It integrates important features of deductive and object-oriented databases. It supports object identity, complex objects, class hierarchy, multiple inheritance with overriding and blocking, and schema. It also supports structured values such as functor objects and sets, treats them as rst class citizens, and p...

This paper presents a modeling approach which couples fuzzy object-oriented database modeling with fuzzy logic. The modeling approach introduced here handles fuzziness at attribute, object/class and class/superclass levels in addition to fuzziness in class/class relationships and various associations among classes. We utilize logical rules to define some of the crisp/fuzzy relationships and ass...

In order to execute database queries eeciently, they are usually translated into an algebra: a small set of operations together with some equivalences. The operations are implemented very eeciently by the database engine, and the equivalences are used to optimise the query. Since query languages for object-oriented databases are more complex than their relational counterparts , the algebra and ...

The management of complexity in large systems is traditionally focused on the modeling and management of classes and hierarchies of classes. In order to improve the compositional flexibility in large systems, this paper turns the focus on objects rather than classes. We will demonstrate that a more powerful object system can ease the development of large systems and can improve the degree of co...

Deep Neural Networks (DNNs) have recently shown outstanding performance on image classification tasks [14]. In this paper we go one step further and address the problem of object detection using DNNs, that is not only classifying but also precisely localizing objects of various classes. We present a simple and yet powerful formulation of object detection as a regression problem to object boundi...

In this paper, we study the problem of recovering the approximate threedimensional shape of an object when knowledge about the object is available. The application of knowledge-based methods to image processing tasks will help overcome problems which arise from processing images using a pixel-based approach. We show that by applying domain specific knowledge, we can fully automate the derivatio...

Demand for efficient software is increasing day by day and object-oriented design technique became able to fulfill this demand because it is the most powerful mechanism to develop efficient software systems. It can not only help in reducing the cost but also helps in the development of high quality software systems. Software developers need appropriate metrics to develop efficient software syst...

Background: Love trauma syndrome includes a set of symptoms manifesting after the end of an emotional relationship and negatively affecting performance in various areas. Objectives: The current study aimed at determining the effect of object relations mediated by cognitive emotion regulation on the prediction of love trauma syndrome in female students. Methods: The correlation-based structura...
