Supporting the development of CAM/DAOP applications: an integrated development process

The increasing complexity of large‐scale distributed applications is driving the Software Engineering community to adopt new software technologies for the development of distributed systems. In this sense, the emergence of component‐based software engineering represents a significant advance towards assembling applications by plugging in pre‐fabricated components. Additionally, the principle of ‘advanced’ separation of concerns is nowadays widely applied to improve modularity, reusability and adaptability of software components. In this way, the aspect‐oriented software development paradigm separates into a new dimension, named aspect, those properties that crosscut the system ‘objects’ or ‘components’, reducing their dependencies. However, the development of software based on the composition of components and aspects is still in its early stages. Part of the reason for this is the lack of well‐defined development processes and tools that help software developers in the use of existing component and aspect‐based approaches. Therefore, the primary aim of this paper is to propose an integrated development process for deriving applications by the assembly of a set of prefabricated components and aspects. This process supports the development of Component‐Aspect Model/Dynamic Aspect‐Oriented Platform (CAM/DAOP) applications, where CAM/DAOP is a new model and platform based on components and aspects. Our intention is to show how, with the support of the integrated development process presented in this paper, it is possible to use CAM/DAOP as an alternative to current distributed platforms.

A software engineering approach for the development of heterogeneous robotic applications

One of the most evident characteristics of robotic applications is heterogeneity: large robotic projects involve many different researchers with very different programming needs and areas of research, using a variety of hardware and software that must be integrated efficiently (i.e.: with a low development cost) to construct applications that satisfy not only classic robotic requirements (fault-tolerance, real-time specifications, intensive access to hardware, etc.) but also software engineering aspects (reusability, maintainability, etc.). Most existing solutions to this problem either do not deal with such heterogeneity or do not cover specific robotic needs. In this paper we propose a framework for the integration of heterogeneous robotic software through a software engineering approach: the BABEL development system, which is aimed to cover the main phases of the application lifecycle (design, implementation, testing, and maintainance) when unavoidable heterogeneity conditions are present. The capabilities of our system are shown by its support for designing and implementing diverse real robotic applications that use several programming languages (C, C++, JAVA), execution platforms (RT-operating systems, MS-Windows, no operating system at all), communication middleware (CORBA, TCP/IP, USB), and also a variety of hardware components (Personal Computers, microcontrollers, and a wide diversity of sensor and actuator devices in mobile robots and manipulator arms).

Evaluating the recovery‐oriented approach through the systematic development of real complex applications

Recovery‐oriented software is built with the perspective that hardware or software failures and operation mistakes are facts to be coped with, as they are problems that cannot be fully solved while developing real complex applications. Consequently, any software will always have a non‐zero chance of failure. Some of these failures may be caused by defects that may be removed or encapsulated. From the point of view of removing or encapsulating defects, a failure is considered to be trivial, when (i) the required effort to identify and eliminate or encapsulate the causing defect is small, (ii) the risk of making mistakes in these steps is also small and (iii) the consequences of the failure are tolerable. It is highly important to design systems in such a way that most (ideally all) of the failures are trivial. Such systems are called ‘debuggable systems’. In this study, we present the results of systematic applying techniques that focus on creating debuggable software for real embedded applications. Copyright © 2008 John Wiley & Sons, Ltd.

A Reference Architecture to support the development of mobile applications based on self-adaptive services

Nowadays, most human daily tasks can be performed by means of Mobile Applications (MobApps). Devices running such applications have some limitations (e.g., processing and storage) compared to personal computers. Therefore, integration of MobApps into service-based systems has been a feasible alternative to overcome these limitations. Moreover, these applications must be prepared to deal with the changes at runtime (e.g., user’s new needs or modifications in their execution environment). In parallel, Reference Architectures (RA) have been used as an important way to support the development, standardization, and evolution of software systems. Although relevant, RA for the domain of MobApps based on services that require adaptation at runtime is still an issue to be explored in depth. This paper presents a RA for Self-MobApps (named RA4Self-MobApps), which aims to support the development of such applications. To show the applicability of our RA, a case study was conducted. As result, we observe our RA has good perspective to efficiently contribute to the Self-MobApps domain.     

The active components approach for distributed systems development

The development of distributed systems is an intricate task due to inherent characteristics of such systems. In this paper these characteristics are categorised into software engineering, concurrency, distribution and non-functional criteria. Popular classes of distributed systems are classified with respect to these challenges, and it is deduced that modern technological trends lead to the inception of new application classes with increased demands regarding challenges from more than one area. One recent example is the class of ubiquitous computing, which assumes dynamic scenarios in which devices come and go at any time. Furthermore, it is analysed to which extent today's prevailing software development paradigms – object, component, service and agent orientation – are conceptually capable of supporting the challenges. This comparison reveals that each of the paradigms has its own strengths and weaknesses and none addresses all of the challenges. The new active component approach is proposed aiming at a conceptual integration of the existing paradigms in order to tackle all challenges in an intuitive and unified way. The structure, behaviour and composition of active components are explained, and an infrastructure for active components is introduced. To underline the usefulness of the approach real-world applications is presented and an evaluation according to the challenges is given.

Usability of pointing devices for office applications in a moving off-road environment

Three pointing devices (mouse, touch pad, touch screen) were evaluated for usability with a Windows-style menu selection task while in a moving off-road environment. A pilot study determined which commercially available devices had the potential to promote good performance in the environment. Eighteen subjects performed a series of complex pointing tasks that simulated the use of a standard application in a moving tractor. The devices were also rated for subjective usability. The mouse and the touch screen produced the best performances, with the mouse receiving the best subjective usability ratings. The participants had a significantly lower performance with the touch pad, which also received lower ratings in the subjective usability ratings.
