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"....
LTE has become a commercial communication technology worldwide, and its security issues are attracting more and more attention. Tracking Area Update (TAU) is a series of procedures performed by LTE system when users update Tracking Area (TA). The security of TAU procedure directly affects the whole system. This paper first analyzes the security of LTE core networks when the TA updates, then it puts...
In this paper, we propose a new architecture for LTE/EPC network by leveraging the Openflow technology. We focus on making detail procedures for initial attach and default bearer setup in Openflow-enabled LTE/EPC network. By numerical analysis, we show the reduction of the signaling load of this procedure in our architecture compared to that in the traditional LTE/EPC architecture.
The demonstrator shows a self-management system for heterogeneous mobile wireless networks that uses context-specific and weighted Key Performance Indicator (KPI) target values defined by the operator to automatically and autonomously configure and control the operation of Self-Organising Network (SON) functions such that they contribute to achieving these KPI targets by appropriately optimising the...
This poster paper presents a high-level description of the Metalogue project that is developing a multi-modal dialogue system that is able to implement interactive behaviors that seem natural to users and is flexible enough to exploit the full potential of multimodal interaction. We provide an outline of the initial work undertaken to define a an open architecture for the integrated Metalogue system...
Contemporary software systems are becoming increasingly large, heterogeneous, and decentralised. They operate in dynamic environments and their architectures exhibit complex trade-offs across dimensions of goals, time, and interaction, which emerges internally from the systems and externally from their environment. This gives rise to the vision of self-aware architecture, where design decisions and...
Contemporary organizations frequently seek external and specialized partners to outsource some of their non-core, though highly complex tasks, including their information systems. In literature, a variety of outsourcing risk factors which lead to unsuccessful project outcomes have been identified. Despite many remedies suggested by practitioners and scholars to mitigate these risk factors, empirical...
Following the publication of the article “Graph Minor Approach for Application Mapping on CGRAs” [1] in the proceedings of the International Conference on Field Programmable Technology (ICFPT) 2012, we received correspondence [2] pointing to some inaccuracies in the article. With this correction, we would like to clarify some points that could otherwise be misconstrued.
The advances of pervasive technology offer new standards for user comfort by adding intelligence to ubiquitous home and office appliances. With intelligence being the core of some newly constructed buildings, it is important to design a scalable, robust, context-aware architecture, which not only has enough longevity and evolving capabilities to sustain itself over the building's lifetime, but also...
Concept mapping has been applied in several fields, including curriculum development, learning, and assessment. The validity of concept mapping process has been proven by many empirical studies. The present paper describes a concept map based system that has been conceived for learners' knowledge assessment in process-oriented short and open answers questions SOAQs' evaluation. The presentation of...
Cloud Accounting refers to how cloud usage is recorded and charged. Even in the case of a single cloud provider this task is hard and there is a context which it becomes even worse, known as federated cloud. It happens when a cloud provider dynamically outsources resources to other providers in response to demand variation. In this context, we identified some research addressing this area which developed...
A capstone course can be based on IEEE 1471 recommended practices on system architecture descriptions. Storyboarding helps in capturing all stake holders and associated activities, and leads to forming a context model. Using the context model, series of domain engineering worksets are performed for the completion of the project. Coupled rubrics can be very effectively used to evaluate the project...
The cloud computing landscape has recently developed into a spectrum of cloud architectures, leading to a broad range of management tools for similar operations but specialized for certain deployment scenarios. This both hinders the efficient reuse of algorithmic innovations within cloud management operations and increases the heterogeneity between different management systems. Our overarching goal...
Autonomous digital actors represent the next step in animating 3D characters. How to create such virtual actors remains an open question. This work presents and discusses an agent architecture derived from how real actors learn their art from acting schools. The knowledge base relies on a rule-based system where each rule encodes explicit knowledge into a classification vector which allows agents...
An agent-oriented middleware supporting contextaware and adaptable mLearning service provision within an InfoStation-based University network is presented. The InfoStation's middleware architecture facilitating the users' mobile (WiFi) access to services is described. The agents' interaction is explained in detail.
This paper details the ongoing development of a context-sensitive InfoStation-based architecture supporting the mobile eLearning service provision within a University campus domain. A general overview of this architecture is presented highlighting the main functional entities. Issues concerning the implementation of a context-sensitive service environment within the system are also detailed, including...
Recent advances in mobile, wireless, and sensor technologies provide new possibilities for supporting learning activities that can be spatially distributed and incorporate different physical and environmental sensory data. In this paper, we present our technical efforts in relation to the design and implementation of mobile and web applications that integrate sensory data used to support inquiry-based...
In the last decade, universities and higher education institutes have become more and more interested in using computers to deliver their formative and summative assessments. Therefore, several computer-assisted-assessment systems have been developed. The variance in the application domains of e-assessment has a main influence on having different assessment systems in the same university. Since universities...
