This paper focuses on speaker detection using multispeaker files both for the enrollment phase and for the test phase. This task was introduced during the 2002 NIST speaker recognition evaluation campaign. Enrollment data is composed of three two-speaker files. Test files are also two-speaker records. The system presented here uses a speaker segmentation process based on an HMM conversation mod...

The quality of the software development process directly affects the quality of the software product. To be successful, software development organisations must respond to changes in technology and business circumstances, and therefore software process improvement (SPI) is required. SPI activity relates to any modification that is performed to the software process in order to improve an aspect o...

Die Dynamik der Informationstechnologie und steigende Komplexität von Informationssystemen schlägt sich auch im Informationssicherheitsmanagement nieder. Informationssicherheitsstandards haben sich als generische Lösungen für eine Vielzahl von Aufgaben etabliert. Inwieweit derartige Standards die benötigte ganzheitliche Betrachtung vorsehen ist bislang nicht geklärt. Im vorliegenden Beitrag wir...

OBJECTIVE The purposes of the study were (1) to evaluate the usefulness of the International Standards Organization (ISO) Reference Terminology Model for Nursing Diagnoses as a terminology model for defining nursing diagnostic concepts in the Medical Entities Dictionary (MED) and (2) to create the additional hierarchical structures required for integration of nursing diagnostic concepts into th...

A mathematical model for commercial naphtha catalytic reformer of Tehran refinery was developed. This model includes three sequencing fixed beds of Pt/Al2O3 catalyst at the steady state condition using detailed kinetic scheme involving 26 pseudo-components connected by a network of 47 reactions, in the range of C6 to C9 hydrocarbons. The reaction network consisted dehy...

Developing high-quality asynchronous store-and-forward telemedicine systems (ASFTSs) remains a challenge. However, there is no accepted understanding as to what are the important quality characteristics for this type of software system and/or what defines a mature software process for producing high-quality ASTFSs. Through adopting a multi-step research methodology, we define a quality model fo...

This paper presents the design and implementation of a platform independent Client/Server Brokerage Application based on WWW Technology. This work has been done in the context of the MULTIMEDIATOR Project (ACTS 096). This document is structured in three parts. The first one gives an overview of the MULTIMEDIATOR system, the second one explains the implementation of a Client/Server Model for a s...

An information model supporting core systems engineering design data is presented. The model provides, in conjunction with STEP (ISO 10303) framework services, an infrastructure that facilitates data exchange between design tools used in the systems engineering process. The model has been developed within the SEDRES project (ESPRIT 20496) and will serve as a seed for the standardisation of a fu...

In this paper, we report the experiments we conducted for our participation to the TREC 2011 Web Track. The experiments we conducted this year aim at discovering how the combination of specific external resources in a language modeling fashion can help web search. We use Wikipedia and Google as external resources for different search contexts.

The paper addresses the issue of an efficient implementation and utilization of new management system parts into an existing landscape of standardized management system on the example of the integration of an energy management system (ISO 50001) into a quality management system (ISO 9001) and an environmental management system (ISO 14001). Therefore we conduct a comparative analysis of the ISO ...
