We present RDCL 3D, a “model agnostic” web framework for the design and composition of NFV services and components. The framework allows editing and validating the descriptors of services and components both textually and graphically and supports the interaction with external orchestrators or with deployment and execution environments. RDCL 3D is open source and designed with a modular approach, allowing...
Since the demand for more bandwidth, agile infrastructures and services grows, it becomes challenging for Service Providers like GEANT to manage the proprietary underlay, while keeping costs low. In such a scenario, Software Defined Networking (SDN), open hardware and open source software prove to be key components to address those challenges. After one year of development, SDX-L2 and BoD, the SDN-ization...
For global-market-oriented software applications, it is required that their user interface be translated to local languages so that users from different areas in the world can use the software. A long-term practice in software industry is to hire professional translators or translation companies to perform the translation. However, due to the large number of user-interface labels and target languages,...
This paper presents a design approach to an embedded monitoring system found in distributed renewable energy power systems. The grid connected distributed power system, delivers energy to the consumers located on the micro-grid, operating at distribution voltage levels, and also delivering the remaining surplus energy to the main distribution grid. The aim of this paper is to present the development...
Existing software analysis methods for performanceand coverage are typically tied to the source code of software applications.In this work, we extend these methods to the Graphical User Interfaces (GUI) of applications, motivated by the desire to bring the user perspective into focus of software quality assurance and testing at the GUI level. We present and discuss various profiling procedures, their...
This paper presents a proposal of working method for the development of Virtual Instruments. The method is valid with the design of an open source graphical user interface and its implementation as a virtual instrument to acquire the variables of a prototype of an industrial process for stamping parts. The method is developed in four stages: analysis and modeling, design, construction and validation...
In large software projects, it can be hard to understand the actual architecture of the implemented software systems if current design documents are outdated or do not exist at all. For systems based on the OSGi component specification, which are used to build quite large applications with back-end and front-end services, tools for visualizing the actual architecture can help to understand the system...
Ultrasound machines are undergoing intense research and rapid development in the world of medical imaging. Ultrasound machines with different technical specifications produce different qualities of ultrasound images. As the analysis and interpretation of ultrasound machines depend on the expertise of sonographers and physicians, human errors and mistakes may occur. The objective of this research is...
We present ongoing work on a platform for mobile health and implantable telemetry devices with powerful point-of-contact processing capabilities based on our VivoSoC multi-sensor medical instrumentation SoC, a custom power management IC, and only a few additional components - allowing the realisation of sub-ccm devices. We detail the powerful yet efficient acquisition and parallel processing capabilities...
In this work, a high-level computational environment has been developed for the MIT Electromagnetic Equation Propagation (MEEP) software. Pre-processing and post-processing features have been implemented through the Visualization Toolkit (VTK) framework, in order to provide new graphical features for MEEP. An interactive user interface is available to make a scripting-free MEEP usage. Software engineering...
Software Defined Satellite Networking (SDSN) provides an innovative perspective to manage satellite network through logically centralized network view and standard interfaces between the control and data plane. Significant advantages of SDSN include enabling integration of space and terrestrial network, flexible and efficient resource management, rapid and economical network function updating, etc...
The practitioner interested in reducing software verification effort may found herself lost in the many alternative definitions of Graphical User Interface (GUI) testing that exist and their relation to the notion of system testing. One result of these many definitions is that one may end up testing the same parts of the Software Under Test (SUT), specifically the application logic, twice. To clarify...
In a spectrally congested environment or a spectrally contested environment which often occurs in cyber security applications, multiple signals are often mixed together with significant overlap in spectrum. This makes the signal detection and parameter estimation task very challenging. In our previous work, we have demonstrated the feasibility of using a second order spectrum correlation function...
Architecture comprehension is crucial for appropriately maintaining, evolving and reusing large scale software. However, in an actual software development, architecture descriptions are often insufficient, obsoleted or at worst missing, and most of the maintenance tasks are performed without sufficient understanding of the architecture. While many techniques to extract architectural information from...
Online experimentation have become a common resource in education since the virtual and remote labs (VRLs) allowed the users to interact with a system without been in a laboratory environment. The science and engineering areas needs to teach their student in experimental practices and this implies, in most cases, costly and complex systems. This work shows how new technologies allows a low cost online...
In this paper, we suggest an PLC programming framework integrated with motion control software module. Our programming framework is characterized with the following features. Firstly, the framework provides programming environment for motion control codes. Secondly, the PLC program can be composed and edited by the use of pre-implemented software modules. Finally, we implemented the framework and...
This study evaluated the effectiveness of thumbnails generated using open source image saliency software for representing digitized archival documents. Salient thumbnails were evaluated against a baseline (full images scaled down) in a lab study that assessed the thumbnails' usefulness during finding and re-finding tasks. Results found no significant differences in time or user preference. However,...
A system of unmanned aerial vehicles (UAVs) can be used to provide uninterrupted service to customers by handing the mission from a weary UAV to a fresh one in an automated manner. Toward such a system, we discuss the development of two components: ROS GPS waypoint tracking package and centralized task allocation network system (CTANS). The ROS GPS waypoint tracking package is the first open source...
In view of the problems that existing visual interface development tool are the interface display code and the logic code are higher coupled, and little weaker in portability and lower extensibility. This paper presents a cross platform visual interface development tool based on template and introduces its key design technologies and system structure. The system uses a unified template management...
Operating systems and web browsers have their own local storage of certificate authorities. Import of certificate authority to this storage is simple operation carried out in a few seconds. If unauthorized person is able to import unverified certificate authority into our computer, consequences might be severe. The utility described in this paper enable user to flexibly administrate the way of maintaining...
