Software architecting is about making decisions that have system-wide impact and that shape software product and process alike. While researchers and practitioners have tried to define and scope the role of the architect, social and organizational impacts on the architect and the architecting process are often neglected. The SODA workshop focuses on the social and organizational dimensions in which...
Adapting systems to the changes of their ubiquitous environments is a complex task. The autonomic computing was proposed as a solution to tackle this complexity. It brings a system with self-management capabilities to dynamically adapt itself to context. We are interested in the architectural adaptation approaches of autonomic applications which follow the MAPE-K loop process. During the execution...
In this paper, which describes a work in progress, we wish to propose context aware service delivery, and we focus on distributed human computer interface, in order to exploit the variety of interaction mode/capabilities according to current situation, users, and context. Our aim is providing new kind of more dynamic interaction modes. We particularly focus on the domain of smart-home (including digital...
Emergency command and control centers (CC) are integrated facilities to assist and handle crisis situations. In these CCs, operators suffer both with information shortage and overload. This paper focuses on the information overload problem. Operators often do not have adequate access to information that may be relevant in the decision-making process. In many CC centers, information is stored without...
This paper gives a brief overview of the 11th Workshop on Trends in Enterprise Architecture Research (TEAR) held at EDOC 2016. The paper introduces the Workshop research topics and presents the accepted papers.
In this keynote talk we propose the use of a capability-driven approach to enterprise modeling in order to capture the intertwined relationship among design requirements and environment, as well as the interplay of requirements and design artifacts for the purpose of facilitating enterprise agility.
This paper describes the work involved in developing a script-based PBL environment in Moodle. PLATE-PBL is a Moodle plug-in based entirely on the meta-model of the PBL scripting language. The plug-in dynamically transforms lesson plans developed by a special visual script editor, it then interprets and instantiates equivalent lesson plans in the Moodle's runtime. Lesson plans can also be designed...
As the adoption of Cloud Computing is growing exponentially, a huge sheer amount of data is generated therefore needing to be processed in order to control efficiently what is going within the infrastructure, and also to respond effectively and promptly to security threats. Herein, we provide a highly scalable plugin based and comprehensive solution in order to have a real-time monitoring by reducing...
This paper proposes a CABAC decoder for HEVC that achieves constant high throughput multi-bin decoding with the parallel syntax element parser to solve the dependency problem in the traditional prediction based multi-bin architecture. The hardware implementation with TSMC 90nm CMOS technology can process 1 bins per cycles with 48,430 gate count (270Mbins/sec,) or 3 bins per cycle with 209,422 gate...
Enterprises face the challenge of rapidly adapting to dynamic business environments. The traditional approach to process management is only partially appropriate to this new context, and calls for the advent of new, evolutionary business processes. This new approach attempts to address specific issues related to flexibility and adaptation such as design of easily adaptable processes, dynamic handling...
Large-scale self-organised systems, such as distributed community energy systems, have called for coordination approaches that are able to deal with issues such as heterogeneity, inter-dependence and dynamic variability. Holonic institutions have been proposed as an approach to converging the structuration required for multi-scale, multi-criteria optimisation in nested enterprises with the formal...
In previous work we showed that reflection and Wrappings are useful tools for system integration. But System of Systems integration also needs to accommodate specific hardware challenges. We discuss simple examples from the operation of a single cyber-physical agent that accepts top-down commands, but uses the Wrappings architecture to self-organize its context specific implementation of them. Our...
Context is the brain of ubiquitous computing. All the intelligence to the ubiquitous system comes from the knowledge of the context. The context is obtained after the processing and reasoning of different sensor data. These sensors are physically distributed in real world. With the advancement in sensing, processing and communication technologies, a distributed processing and reasoning has become...
Architecture description can be modeled as a set of alternative choices and decisions, where the rationale and tradeoffs for each decision are documented and understood as needed to inform subsequent decisions. Each decision, based on ISO/IEC/IEEE 42010, pertains to one or more stakeholder concerns. These concerns combined with the system environment and scenarios provide architecture design context...
Experimental platforms (testbeds) play a significant role in the evaluation of new and existing technologies. Their popularity has been raised lately as more and more researchers prefer experimentation over simulation as a way for acquiring more accurate results. This imposes significant challenges in testbed operators since an efficient mechanism is needed to manage the testbed's resources and provision...
Collective intelligence systems (CIS), such as wikis, social networks and content sharing platforms, have dramatically improved knowledge creation and sharing at society level. There is a trend to exploit the stigmergic mechanisms of CIS also at organization/corporate level. However, despite the wide adoption of CIS, there is a lack of consolidated systematic knowledge of the architectural principles...
Although content sharing provides many benefits, content owners lose full control of their content once they are given away. Existing solutions provide limited capabilities of content access control as they are vendor-specific, non-structured and non-flexible. In this paper, we present an open and flexible software solution called SelfProtect Object (SPO). SPO bundles content and policy files in an...
The widespread use of mobile devices such as smartphones and tablets is flanked by an ever increasing supply of mobile applications. Along with this trend, expectations and requirements of users rise as well. For example, users do not want to compromise on comfortable daily routines as available on desktop computers. However, an intrinsic characteristic of mobile devices is their limited availability...
We have investigated approaches in the literature to assess the quality of the software architectures of medical devices, and have found evidence that there is a lack of methodologies for evaluating the software architecture design aspects of medical devices that might affect system safety. Such evidences were identified when evaluating the software architecture of the FDA Generic Infusion Pump searching...
An approach to software architecture creation is described in the context of agile development. It eschews the traditional separation of top-down and bottom-up design. A concrete, cumulative, least-commitment process is demonstrated that establishes an architecture core likely to remain stable as requirements are added.
