In earlier work, we showed that the AspectJ notions of aspect and class can be unified in a new module construct that we called the classpect, and that this new model is simpler and able to accommodate a broader set of requirements for modular solutions to complex integration problems. We embodied our unified model in the Eos language design. The main contribution of this paper is a case study,...

The Enterprise parallel programming system allows programmers to create, compile, execute, and debug parallel applications that execute over a network of workstations. The run-time system, which is responsible for the correct execution of user programs, was redesigned and re-implemented using object-oriented technology. This paper details the object-oriented components of the design where the C...

Design patterns capture recurring patterns of object-oriented design. This tutorial will provide a perspective on what it’s like to design and implement applications against a backdrop of design patterns. Furthermore, by carrying the designs through to implementation, we will demonstrate the way in which design patterns may or may not be reflected directly in the implementation. We will discuss...

In this paper, we present an approach for crowd detection based on an ensemble of classifiers which employ several feature representation schemes of crowd images, including, local ternary patterns, local binary patterns, and features based on the spatial gray level dependency matrix. A Support Vector Machine classifier is trained on each of these feature vectors. Classifier predictions are then...

A Design Pattern presents a proven solution to a common design problem using a combination of informal text, diagrams, and examples. Often, to suitably describe an issue, the author of a Design Pattern must spread and repeat information throughout the Pattern description. Unfortunately, spreading the information can make it difficult for a reader to grasp subtleties in the design, leading to po...

In this paper, we present eXtreme Design with Content Ontology Design Patterns (XD): a collaborative, incremental, iterative method for pattern-based ontology design. We also describe the first version of a supporting tool that has been implemented and is available as a plugin for the NeOn Toolkit. XD is defined in the context of a general approach to ontology design based on patterns, which is...
