During face-to-face interactions, people naturally integrate nonverbal behaviors such as facial expressions and body postures as part of the conversation to infer the communicative intent or emotional state of their interlocutor. The interpretation of these nonverbal behaviors will often be contextualized by interactional cues such as the previous spoken question, the general discussion topic or the...
Securing critical systems such as Cyber-Physical Systems (CPS) is an important feature especially when it comes to critical transmitted data in a real-time environment. At the same time, the implementation of security counter-measures in such systems may impact transmission delays of critical tasks. For this reason selecting proper security mechanisms in such critical systems is an important issue...
Mobility as a Service takes the concept of XaaS to transportation: a MaaS provider shall merge transport options from different mobility providers, seamlessly handling the whole experience of traveling, from providing information, to travel planning, and payments handling. To effectively support the creation of a market of MaaS providers, we envision the creation of ICT infrastructures based on microservices,...
This paper presents a conceptual framework for building a recommendation engine for use in the ubiquitous consumer wireless world (UCWW). The framework is based on the Lambda Architecture and as such provides real-time recommendations at the speed layer and off-time analytical operations at the batch layer. Moreover, at the speed layer, a root server is used for updating the real-time recommendation...
Context Aware Systems (CAS) support mobility of users and make context reasoning efficiently to provide relevant and real-time information. CAS should be particularly adaptive and aware by managing and responding properly to occurring events. Due mainly to the presence of numerous sensors and access to several communication networks, Context-awareness has been successfully included in the mobile device...
In this paper, we consider two Network-on-Chip (NoC) architectures used within commercially available many-core systems, namely Tilera TILE64 which implements flow regulation within routers and KalRay MPPA 256 which implements flow regulation in source nodes. The Worst-Case Traversal Time (WCTT) on the NoC has to be bounded for real-time applications, and buffers should never overflow. Different worst-case...
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...
In the international standards for architecture descriptions in systems and software engineering (ISO/IEC/IEEE 42010), “concern” is a primary concept that often manifests itself in relation to the quality attributes or “ilities” that a system is expected to exhibit — qualities such as reliability, security and modifiability. One of the main uses of an architecture description is to serve as a basis...
If visions and forecasts of industry come true then we will be soon surrounded by billions of interconnected embedded devices. We will interact with them in a cyber-human symbiosis, they will not only observe us but also our environment, and they will be part of many visible and ubiquitous objects around us. The information that is collectively gathered and analyzed is supposed to help us in our daily...
We propose a novel software platform based on the notion of context-awareness which allows rapid and easy development of context aware applications. One of the fundamental goals of the proposed platform is extensibility, allowing the platform to react to new requirements without making fundamental and substantial changes. The Context Aware Application Development Platform- PCAD- has inspired from...
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...
The paper describes an innovative and fully cognitive approach which offers the opportunity to cope with some key limitations of the present telecommunication networks by means of the introduction of a novel architecture design in the perspective of the emerging Future Internet framework. Within this architecture, the Quality of Experience (QoE) Management functionalities are aimed at approaching...
Graphics processing units (GPUs) are being widely used as co-processors in many application domains to accelerate general-purpose workloads that are computationally intensive, known as GPGPU computing. Real-time multi-tasking support is a critical requirement for many emerging GPGPU computing domains. However, due to the asynchronous and non-preemptive nature of GPU processing, in multi-tasking environments,...
We present ongoing work to develop a software tool for estimating worst-case execution times for real-time, embedded programs. The tool applies static analysis to executable machine-code programs. Currently we mainly aim at supporting the TSC-21020E Digital Signal Processor, but the tool is designed to be easy to adapt to other target processors as well. Contrary to most other WCET tools we attempt...
The Embedded system is controlled with the combination of hardware and software. They are usually processed by a microprocessor / microcontroller that execute instructions which are present in ROM. The term "embedded" reflects to the fact that they are part of the system. Real-Time Operating System (RTOS) combines with two thoughts "real-time" and "operating system"....
Today, data from different sources and different phases of the product life cycle are usually analyzed in isolation and with considerable time delay. Real-time integrated analytics is especially beneficial in a production context. We present an architecture for data- and analytics-driven exception escalation in manufacturing and show the advantages of integrating unstructured data.
An important issue related to Real-Time Operating Systems is the handling of interrupts, timers, mutexes, watchdog timers, synchronization and communication directives as unitary events. In order to obtain a predictable response time for the different types of events that occur simultaneously, it is necessary to have a prioritization mechanism for them. Therefore, this paper proposes a hardware mechanism...
In response to the challenges for application development, deployment, running and maintenance in an open, dynamic, difficult to control for Internet platform, the concept of Internetware came into being. It is a new software architecture, which is flexible to evolution, continuously reactive and adaptive to multiple targets. Software entities form a software web, which is similar to current information...
In the most Real Time Operating Systems (RTOS), the interrupt handlers are implemented in software and they can increase the response time to external events and the overload of the CPU. Therefore, the newest RTOSs implement in hardware the interrupt handlers in order to eliminate these two problems. By analyzing traditional models for the management of interrupts, we can emphasize their inability...
Within a cost-constrained economic environment, the DoD, government agencies, and commercial businesses seek to maximize mission capacity by sharing services across mission segments over an integrated infrastructure using a common mission control system. To accomplish this goal, a new technique is required to orchestrate the execution of existing and emerging mission services. The Dynamic Mission...
