Enhancing the Process of Testing Object -Oriented Systems.

Testing is a crucial step in the overall system development process. Using testing techniques that support features of the underlying software paradigm more effectively tests program than do testing techniques that support features of other paradigms. Systems developed with the object-oriented paradigm require techniques that support object-oriented features such as inheritance, data abstraction, encapsulation, and dynamic binding. Many techniques that are used to test systems developed with the structured paradigm are not sufficient for the testing of object-oriented systems. The goal of this research is to develop methods that will improve the process of testing object-oriented systems. Specifically, emphasis is given to improving the level of testing of methods because the level of method testing is generally considered inadequate. Algorithms are included that identify the set of methods, both interobject and intraobject, that should be tested for a given system. These algorithms are implemented as a part of an automated testing system that derives a framework for the testing of methods. This system includes the automatic generation of test drivers to facilitate the testing. It captures the results of tests for the purposes of reuse for future system maintenance. This framework provides the software engineer who is testing a system a mechanism to determine the level of method coverage that has been achieved in the testing process

A conceptual framework for circular design

Design has been recognised in the literature as a catalyst to move away from the traditional model of take-make-dispose to achieve a more restorative, regenerative and circular economy. As such, for a circular economy to thrive, products need to be designed for closed loops, as well as be adapted to generate revenues. This should not only be at the point of purchase, but also during use, and be supported by low-cost return chains and reprocessing structures, as well as effective policy and regulation. To date, most academic and grey literature on the circular economy has focused primarily on the development of new business models, with some of the latter studies addressing design strategies for a circular economy, specifically in the area of resource cycles and design for product life extension. However, these studies primarily consider a limited spectrum of the technical and biological cycles where materials are recovered and restored and nutrients (e.g., materials, energy, water) are regenerated. This provides little guidance or clarity for designers wishing to design for new circular business models in practice. As such, this paper aims to address this gap by systematically analysing previous literature on Design for Sustainability (DfX) (e.g., design for resource conservation, design for slowing resource loops and whole systems design) and links these approaches to the current literature on circular business models. A conceptual framework is developed for circular economy design strategies. From this conceptual framework, recommendations are made to enable designers to fully consider the holistic implications for design within a circular economy

Reusing enterprise models to build platform independent computer models

Enterprises use enterprise models to represent and analyse their processes, products, decisions, organisation, information flows, etc. Nevertheless, the enterprise knowledge that exists in enterprise models is not used beyond these purposes. The main goal of this paper is to present a framework that allows enterprises to reuse enterprise models to build software. The framework includes these dimensions: (1) a methodology that guides the use of the other dimensions in the reutilisation of enterprise models in software generation; (2) a set of metamodels to represent enterprises at the Computation Independent Model (CIM) level; (3) a modelling guide to make enterprise models using the metamodels proposed in this paper; (4) an extraction algorithm to discriminate the part of the CIM model to reuse; and (5) a set of transformation rules to reuse enterprise models to build Platform Independent Models. In addition, a case example is shown to validate the work that was carried out and to identify limitations

Development framework pattern for pervasive information systems

During last decade, the world watched a social acceptance of computing and computers, enhanced information technology devices, wireless networks, and Internet; they gradually became a fundamental resource for individuals. Nowadays, people, organizations, and the environment are empowered by computing devices and systems; they depend on services offered by modern Pervasive Information Systems supported by complex software systems and technology. Research on software development for PIS-delivered information, on issues and challenges on software development for them, and several other contributions have been delivered. Among these contributions are a development framework for PIS, a profiling and framing structure approach, and a SPEM 2.0 extension. This chapter, revisiting these contributions, provides an additional contribution: a pattern to support the use of the development framework and profiling approach on software development for PIS. This contribution completes a first series of contributions for the development of PIS. This chapter also presents a case study that allowed demonstrating the applicability of these contribution

Towards Making Distributed RDF processing FLINker

In the last decade, the Resource Description Framework (RDF) has become the de-facto standard for publishing semantic data on the Web. This steady adoption has led to a significant increase in the number and volume of available RDF datasets, exceeding the capabilities of traditional RDF stores. This scenario has introduced severe big semantic data challenges when it comes to managing and querying RDF data at Web scale. Despite the existence of various off-the-shelf Big Data platforms, processing RDF in a distributed environment remains a significant challenge. In this position paper, based on an indepth analysis of the state of the art, we propose to manage large RDF datasets in Flink, a well-known scalable distributed Big Data processing framework. Our approach, which we refer to as FLINKer extends the native graph abstraction of Flink, called Gelly, with RDF graph and SPARQL query processing capabilities

What we know about anticonsumption: An attempt to nail jelly to the wall

Despite burgeoning academic interest in anticonsumption, a lack of definitional clarity and overlapping constructs beleaguer the pertinent literature, preventing research in the field from reaching its full potential. This paper aims to strengthen the foundations for advancing knowledge in this fragmented field by (a) undertaking a thorough systematic review of literature; (b) charting the scope of anticonsumption literature based on network analysis and attempting to delineate overlapping areas; (c) providing an integrated framework of anticonsumption research, including antecedents, moderators, and consequences; and (d) suggesting a set of specific research propositions that will enable the field to move forward. Toward these aims, we analyzed 120 anticonsumption papers revealed in the literature review, identifying a number of important anticonsumption‐related topics that warrant further investigation. Moreover, we suggest a research framework which reveals antecedents, causal sequences, and consequences of anticonsumption. Finally, a research agenda based on this integrated framework indicates promising areas for future research

Extensibility of Enterprise Modelling Languages

Die Arbeit adressiert insgesamt drei Forschungsschwerpunkte. Der erste Schwerpunkt setzt sich mit zu entwickelnden BPMN-Erweiterungen auseinander und stellt deren methodische Implikationen im Rahmen der bestehenden Sprachstandards dar. Dies umfasst zum einen ganz konkrete Spracherweiterungen wie z. B. BPMN4CP, eine BPMN-Erweiterung zur multi-perspektivischen Modellierung von klinischen Behandlungspfaden. Zum anderen betrifft dieser Teil auch modellierungsmethodische Konsequenzen, um parallel sowohl die zugrunde liegende Sprache (d. h. das BPMN-Metamodell) als auch die Methode zur Erweiterungsentwicklung zu verbessern und somit den festgestellten Unzulänglichkeiten zu begegnen. Der zweite Schwerpunkt adressiert die Untersuchung von sprachunabhängigen Fragen der Erweiterbarkeit, welche sich entweder während der Bearbeitung des ersten Teils ergeben haben oder aus dessen Ergebnissen induktiv geschlossen wurden. Der Forschungsschwerpunkt fokussiert dabei insbesondere eine Konsolidierung bestehender Terminologien, die Beschreibung generisch anwendbarer Erweiterungsmechanismen sowie die nutzerorientierte Analyse eines potentiellen Erweiterungsbedarfs. Dieser Teil bereitet somit die Entwicklung einer generischen Erweiterungsmethode grundlegend vor. Hierzu zählt auch die fundamentale Auseinandersetzung mit Unternehmensmodellierungssprachen generell, da nur eine ganzheitliche, widerspruchsfreie und integrierte Sprachdefinition Erweiterungen überhaupt ermöglichen und gelingen lassen kann. Dies betrifft beispielsweise die Spezifikation der intendierten Semantik einer Sprache

CONTENT BASED RETRIEVAL OF LECTURE VIDEO REPOSITORY: LITERATURE REVIEW

Multimedia has a significant role in communicating the information and a large amount of multimedia repositories make the browsing, retrieval and delivery of video contents. For higher education, using video as a tool for learning and teaching through multimedia application is a considerable promise. Many universities adopt educational systems where the teacher lecture is video recorded and the video lecture is made available to students with minimum post-processing effort. Since each video may cover many subjects, it is critical for an e-Learning environment to have content-based video searching capabilities to meet diverse individual learning needs. The present paper reviewed 120+ core research article on the content based retrieval of the lecture video repositories hosted on cloud by government academic and research organization of India
