The purpose of this article is to describe the results of a clinical trial in which telephonic case management was evaluated as a supplement to substance abuse treatment. An interactive voice response system (IVR) was developed by the research team for use in the case management of randomly assigned participants in a clinical trial research project. The features of the software program facilita...

At this time, telecommunication networks are present everywhere. These networks are not only rather complex, but they are also made up of different components. That is the reason telecommunication network management (TNM) is so relevant. This paper deals with two important aspects of telecommunication network management: managed objects and expert system rules. Definition of objects is based on...

The rise of digital platforms is changing organizations, markets and the logic of innovation in the digital economy. In particular, telecommunication companies re-structure their business models to gain control of innovative services and digital platforms. In this light, we aim to advance research on digital platform business models conducting a frameworkbased case study analysis of telecommuni...

This paper studies how the home automation standard Tilidomotis (in the process of standardization) has been adapted to radio medium. Afrer presenting the Tilidomotis standard and concept, the paper highlights the constraints and characteristics of the radio medium in the 433 MHz ISM band. A protocol stack fitting these constraints is then introduced. The main characteristics of the low layer s...

Telecommunication companies have received a great deal of research attention, which have many advantages such as low cost, higher qualification, simple installation and maintenance, and high reliability. However, the using of technical maintenance approaches in Telecommunication companies could improve system reliability and users' satisfaction from Asymmetric digital subscriber line (ADSL) ser...

In this paper an agent based framework for service deployment in telecommunication networks is presented. The framework is intended to improve the process of service deployment in next generation telecommunication networks. This process has been complicated with the introduction of new actors and the migration of service infrastructure from the telecommunication provider to the third-party valu...

This paper describes a real-time implementation of a multirate (2.4, 4.8, 8 and 16 Kbit/sec) speech codec designed to fulfil the requirements of the telecommunication sub-system for HERMES spacecraft. Considering these requirements, our choice tumed to the Multi-Pulse Excited Linear Predictive Coding (MPLPC) approach (except for the 2.4 Kbit/sec emergency rate which is based on the standard LPC...

We demonstrate experimentally that spontaneous parametric down-conversion in an AlxGa(1-x)As semiconductor Bragg reflection waveguide can make for paired photons highly entangled in the polarization degree of freedom at the telecommunication wavelength of 1550 nm. The pairs of photons show visibility higher than 90% in several polarization bases and violate a Clauser-Horne-Shimony-Holt Bell-lik...

We report a defect state based guided-wave photoconductive detector at 1360-1630 nm telecommunication wavelength directly in standard microelectronics CMOS processes, with zero in-foundry process modification. The defect states in the polysilicon used to define a transistor gate assists light absorption. The body crystalline silicon helps form an inverse ridge waveguide to confine optical mode....

Most telecommunication operators are moving cautiously with their video-based services rollouts because of video service assurance concerns. Competition between providers is fierce and the key to success is to provide a service with the highest possible level of user satisfaction (QoE – Quality of Experience) is to some extent related to network transmission parameters (commonly referred to as ...
