Software-as-a-Service in the Telecommunication Industry: Problems and Opportunities

2010

This paper examines the telecommunication software market and the adoption of topical Software-as-a-Service (SaaS) model in this vertical market. The aim of this paper is to estimate which telecommunication software products are likely to be provided as a Service, and to examine the potential factors disallowing SaaS adoption. The set aim is pursued by studying both the supplying software vendors and the communication service providers (CSP) as customers. A set of thematic interviews, software industry statistics and information disclosed by the software vendors are used in the analysis. The results of the analysis reveal challenges in adopting SaaS for telecommunication software as well as…

GUI Usability in Medical Imaging

2009

The diffusion of computer technologies in everyday life has involved the birth of standard methodologies to control their development. Indeed, the purpose of standardization procedures consists of providing rules aimed to control technologies leaving no space for empirical improvisations. In general, medical software manufacturers provide their applications with Graphic User Interfaces (GUI) that are not compliant with any clear and standard usability criterion. The only guideline is the creation of GUIs inherited from the ones adopted on medical consoles because physicians use them routinely. This paper addresses this issue: medical software interfaces should be designed trying to overcome…

Visualization of EDI messages

2003

Multi-organizational EDI message networks are complicated communication environments with various standards and technologies. The role of third party message exchange hubs has become more important and their tasks more difficult. Current development activities for supporting the utilization of XML in electronic commerce focuses on message standardization and specification of common business architectures, processes, and web practices. A need to visualize EDI messages in different contexts to human readers has received insufficient attention in ongoing activities. In this paper we discuss problems and approaches related to the visualization of EDI messages in XML format. An idea of a standar…

Context-aware vehicular cyber-physical systems with cloud support: architecture, challenges, and solutions

2014

[EN] The advances in wireless communication techniques, mobile cloud computing, and context-aware technologies boost a growing interest in the design, development, and deployment of vehicular networks for emerging applications. This leads to an increasing evolutionary tendency to change from vehicular networks toward cloud-assisted context-aware vehicular cyber-physical systems. In this article, we first propose a multi-layered context-aware architecture and introduce two crucial service components, vehicular social networks and context-aware vehicular security. Then we propose an application scenario regarding the context-aware dynamic parking services by illuminating the cloud-assisted ar…

Integrating Variability Management in Data Center Networks

2017

International audience; Data centers have an important role in supporting cloud computing services (i.e. checking social media, sending emails, video conferencing,..). Hence, data centers topologies design became more important and must be able to respond to ever changing service requirements and application demands. An ultimate challenge in this research is the design of data center network that interconnects the massive number of servers, and provides efficient and fault-tolerant routing algorithm. Several topologies such as DCell, FlatNet and ScalNet have been proposed. However, these topologies generally seek to improve the scalability without taking into consideration the energy usage …

An Approach to Cadastral Map Quality Evaluation in the Republic of Latvia

2009

An approach to cadastral map quality evaluation is proposed, which is elaborated and implemented by State Land Service of the Republic of Latvia. The approach is based on opinion of Land Service experts about cadastral map quality that depends on its usage points. Quality parameters of cadastral map objects identified by experts and its limit values are used for evaluation. The assessment matrix is used, which allow to define cadastral map quality that depends on its usage purpose. The matrix is used to find out, of what quality a cadastral map should be in order to be used for the chosen purpose. The given approach is flexible, it gives a possibility to change sets of quality parameters an…

Advertising Peer-To-Peer Networks over the Internet

2002

Weber, Matthieu Advertising Peer-to-Peer Networks over the Internet Jyvaskyla: University of Jyvaskyla, 2006, 120 p. (Jyvaskyla Licentiate Theses in Computing ISSN 1795-9713; 7) ISBN 951-39-2329-0 Finnish summary Most peer-to-peer networks nowadays are decentralized or even fully distributed, meaning that they do not require a central authority for proper operation. Joining such networks is however often performed by using a central directory of its members, thus breaking their decentralized characteristic. This work proposes an advertisement system for peer-to-peer networks that does not rely on a central service, nor requires any dedicated infrastructure to be setup, using only already ex…

Comparative Analysis of Natural Gas Pipeline Interconnections

2021

The paper shows a comparison between two intervention methods for interconnecting two gas transmission pipelines within a natural gas transmission system. One intervention implies shutdown of pipelines, while the other one in-service pipelines. Each method is described in detail along with the main technological issues, as well as the related advantages and disadvantages. The technological procedures imply special working techniques such as welding or hot tapping in service pipelines.

Model-based approaches for the development of event-based systems using embedded services

2010

This paper presents a development use case of event-based system using (embedded) services specified in UPnP specification. Although we use only UPnP, we considered that the use case is also applicable for other (XML-based) service description technologies.

2019

Background Key elements of instructional quality include the teacher's ability to immediately react in domain-specific classroom situations. Such skills - defined as action-related skills - can only be validly assessed using authentic representations of real-life teaching practice. However, research has not yet explained how teachers apply domain-specific knowledge for teaching and to what extent action-related skills are transferable from one domain to another. Aims Our study aims to examine (1) the relationship between action-related skills, content knowledge, and pedagogical content knowledge, and (2) the domain specificity of action-related skills of (prospective) teachers in the two do…
