A speech recognition approach for an industrial training station
2021
This paper presents a speech recognition service used in the context of commanding and guiding the activities around an industrial training station. The entire concept is built on a decentralized microservice architecture and one of the many hardware and software components is the speech recognition engine. This engine grants users the possibility to interact seamlessly with other components in order to ensure a gradual and productive learning process. By working with different API’s for both English and Romanian languages, the presented approach manages to obtain good speech recognition for defining task phrases aiding the training procedure and to reduce the recognition required time by a…
Activity typologies as a design model for the ubiquitous detection of daily routines
2018
Emerging technologies open up new visions and business potential for systems design and development in the areas of wellbeing and health. New technologies enable the detection of human performance and early changes in physical and cognitive functioning, making it possible to monitor an older person’s wellbeing. This kind of technology or service sets significant requirements for design, as design concepts must be able to capture the complexity of people’s daily lives in terms of activities and environments. Technology itself is “blind” unless designers can adapt it to human life. There is thus a distinct need for comprehensive design and development models that generate adequate human requi…
Cloud Based Business Processes Orchestration
2014
Abstract As the value concept of the cloud is evolving from a cost-saving mechanism into a growth instrument, more and more organizations are turning to the cloud in an attempt to redesign their core business processes. The opportunity for process innovation is vast, and it will take the disciplined approach of BPM, with the computing understanding and accessibility of the cloud, to make the most of what lies ahead. With the popularity of cloud computing, Platform-as-a Service (PaaS) becomes one of the core technical enablers of enterprises to change the delivery of services to both customers and internal organizations. An application in an enterprise needs to take into account various spec…
Which Test Artifacts Testing Service Providers should Reuse and How? Experiences from a Case Study in the Chinese ICT Sourcing Market
2011
Software testing service providers are facing new requirements to shorten service times, lower costs, and increase service customization and quality. Reuse of test artifacts is a possible solution that can help providers to meet the requirements because reuse can improve software quality and productivity. However, the extant literature does not explain in depth which test artifacts should be reused and how. This paper focuses on ICT-enabled sourcing of software testing services in the Chinese market to identify the most important reusable test artifacts. There are two reasons for this research. First, most Chinese service providers are small or medium-sized and have to overcome obstacles su…
IN service specification using the KANNEL language
1995
KANNEL is an application-oriented language for protocol engineering, with integrated support for all the main aspects of implementing typical communications software. Intelligent network services with distributed and interacting components share a number of central features with communications protocols, thus bringing in the possibility of applying protocol engineering techniques within the area of intelligent networking. To verify this view, the KANNEL language is applied to the specification of an intelligent calling card service. The specification includes both visual and textual notations of KANNEL.
Interaction Mechanism of Humans in a Cyber-Physical Environment
2015
The research initiative “Industrie 4.0” (I4.0) of the high-tech strategy announced by the German government targets the deployment of a cyber-physical system (CPS) in production and logistics. Such CPS-based environments are characterized by an increasing number of heterogeneous intelligent autonomous and communicating artifacts tightly integrated with humans. Thus, the human’s role will become a composite factor (“man-in-the-mesh”) for this future CPS environment, playing more than just a simple role inside the control loop. This paper investigates the need of a robust communication between CPS and humans, which includes a clear semantic of the exchanged information. For this purpose, a me…
A Study on Distributed Fault-Tolerant Service Architectures for Critical Software Systems
2021
Reliable systems have been the subject of much research in the past years, with societal dependency on computer systems becoming more and more apparent. With more and more organizations embracing DevOps culture, there is a persistent need to understand how these systems are built and what their trade-offs are. This paper discusses and benchmarks the components of a modern fault tolerant and easily scalable system, designed to maximize up-time. The paper also describes the techniques used in the development of such a system. The system architecture described is implemented through several services deployed for a new critical single sign-on system deployed at CERN (The European Laboratory for…
Mobile agents and grid computing
2004
Publisher Summary This chapter describes mobile agents as an effective solution for grid service provision. A short overview is first introduced on the grid paradigm and the most known research activities in the field. Then, mobile agents are discussed and a comparison with the remote procedure call (RPC) method is made as far as the most effective solution to minimize network overload and fault occurrences is concerned. The common feature of all grid architectures is a coordinated and controlled resource sharing between the members of a dynamic multi-institutional virtual community. Community members agree on a set of sharing rules and permissions, by which resources to be shared and membe…
An Integrated Multi-service Software Simulation Platform: SIMPSONS Architecture
2005
This paper describes SIMPSONS (SIp and MPls Simulations On NS-2), which is a software platform for simulating multiple network scenarios, such as Telephony Over IP (TOIP), and multi-services networks extending the functionalities of Network Simulator NS-2. The innovative aspects of SIMPSONS is the complete integration of control protocols and traffic engineering mechanisms inside the same simulation tool. In fact, next generation networks must meet basically two fundamental requirements: support of Quality of Service (QoS) and Traffic Engineering (TE) functionalities. SIMPSONS is able to simulate DiffServ, MPLS, OSPF and SIP and their interaction in everything TOIP scenario. So with this po…
Kata Containers: An Emerging Architecture for Enabling MEC Services in Fast and Secure Way
2019
New coming applications will be only possible through Mobile Edge Servers deployed in proximity of the mobile users. Due to the user's mobility and server's workload, service migration will be an integral part of the services. For this reason, a standardized architecture should be designed to accomplish a workload migration in a secure and timely manner. Most research done to date has focused on the use of either virtual machine (VM) or container or a mix of both recently. A final solution might be an architecture only having the advantages of both technologies as the security of the VM and the speed of the containers. Custom solutions, actually, by using both technologies, need continuous …
