We present a component-oriented approach to demonstrate the use of the Unified Modeling Language (UML) and Open Distributed Processing (ODP) concepts to design service components of a telecommunications management system. This paper is based on the work done in the design phase of the ACTS project " TRUMPET " (Inter-Domain Management with Integrity). This(More)
BACKGROUND Deaths from tuberculosis (TB) continue to occur despite the availability of effective antimicrobial agents. Multidrug resistance, human immunodeficiency virus (HIV) infection, and delayed therapy have been implicated. OBJECTIVE To examine clinical factors associated with in-hospital death in patients with active TB. METHODS A retrospective(More)
Sensor Networks [6, 5] consist of a large number of low-cost low-power devices, each with sufficient hardware to monitor one or more variables and send and receive the readings for these variables to other devices. Wireless sensor networks are becoming a powerful tool for monitoring a range of diverse situations [3, 8]. While the devices themselves are(More)
— It is has been previously demonstrated [4] that Internet topologies which were once considered unstructured networks with no global design processes actually follow power-laws, both at the router level and the AS (Autonomous System) domain level. This discovery has very wide implications on network research as well as network and protocol design. The(More)
BACKGROUND Delays in the diagnosis of tuberculosis may result in increased patient morbidity and in further spread of the disease. We examined the clinical acumen of the medical staff in the diagnosis of tuberculosis and investigated the reasons for delay in the identification and treatment of patients with pulmonary tuberculosis. METHODS A retrospective(More)
Recently Active Networks were proposed as the approach that will enable quick introduction of new services in the current telecommunication infrastructure. This approach allows third party executable codes (proxylet) to be deployed into the network, which creates a big security risk. In this paper we present the application of Bayesian technology in the(More)
Nosocomial multidrug-resistant tuberculosis (MDR-TB) in human immunodeficiency virus (HIV)-infected people is recognized in Europe and America. We report the first such outbreak in South Africa. Six hospitalized women, identified by DNA fingerprinting, were infected with an outbreak strain of MDR-TB while receiving treatment for drug-susceptible(More)
— Sensor networks in environmental monitoring applications aim to provide scientists with a useful spatio-temporal representation of the observed phenomena. This helps to deepen their understanding of the environmental signals that cover large geographic areas. In this paper, the spatial aspect of this data handling requirement is met by creating clusters(More)
A proportion of patients with drug-resistant and drug-susceptible tuberculosis (TB) have sputum that is smear and culture positive for Mycobacterium tuberculosis for a prolonged period of time, despite conventional therapy. Among such patients with refractory TB, an unblinded, observational study was undertaken that used conventional TB therapy and(More)
