A blood pre-centrifugation delay of 24 h at room temperature influenced the proton NMR spectroscopic profiles of human serum. A blood pre-centrifugation delay of 24 h at 4°C did not influence the spectroscopic profile as compared with 4 h delays at either room temperature or 4°C. Five or ten serum freeze-thaw cycles also influenced the proton NMR spectroscopic profiles. Certain common in vitro ...

Profile is a relationship between a response variable and one or more independent variables which can describe quality of a process or a product. On the other hand, for an in-control process, capability indices are criteria for the process quality improvement that allows to meet customers’ expectations. Despite a considerable number of applications and monitoring methods already proposed for pr...

This paper proposes a multi HLR scheme for location management in PCS network instead of having a single HLR. In conventional architecture we have a single HLR that acts as centralized database to store the user profile along with the MT’s location information. This approach of single HLR suffers from two major disadvantages: bottleneck and call misrouting during the peak load. In multi HLR arc...

Population screening may harm quality of life (QoL), and traditional health-related QoL tools could be inadequate to evaluate this risk. Two global and generic QoL instruments were developed for studying the QoL consequences of screening (SCREENQOL), and QoL variation in a normal population (SEQOL). SCREENQOL and SEQOL (Self-Evaluation of Quality of Life Questionnaire) are self-administered que...

Conceptual modelling is an important aspect in designing systems. However, the use of conceptual models in knowledge-based system (KBS) is limited as there is no particular consensus on which modelling language should be used and most of these systems are developed in a 'problem to code' manner. This paper focuses on the use ofa Unified Modeling Language (UML) Profile for conceptual knowledge m...

RÉSUMÉ. L’hétérogénéité des techniques d'accès à l'information a soulevé le problème de la définition d’un modèle homogène qui leur servirait de base. Dans cet article, nous proposons un modèle générique de profil qui permet de décrire la structure et la sémantique générale de tout type de profil d’information ou d’usager pour l’accès à l’information. Nous construisons également un graphe séman...

High peak loads at transformer stations in domestic residences are expected where heating is provided merely by heat pumps with additional electric heating. Two scenarios are studied: the event of a black start and high electricity demand on a day with a very low outdoor temperature. The simulation is done with agents representing up to 100 dwellings based on PowerMatcher technology. The result...

On-going changes in the electric utility industry are imposing ever-stricter constraints upon the operators of transmission networks. The increase in peak load and reduced power margins in the network may under certain circumstances conspire to produce brownouts, or even blackouts, especially when compounded with low probability contingencies. The challenge is also imposed on generation capacit...
