Building robust network monitoring applications is hard given the unpredictable nature of network traffic. Complex analysis on streaming network data usually leads to overload situations when presented with anomalous traffic, extreme traffic mixes or highly variable rates. We present an on-line predictive load shedding scheme for monitoring systems that quickly reacts to overload situations by ...

The concept of allostatic load (AL) represents the cost of the continual adjustment of the internal milieu required by an organism to adapt to different challenges. The majority of studies concerning AL have focused mainly on identifying its biological components. Recently, new criteria for a clinimetric evaluation of AL have been introduced, adding a new definition of allostatic overload (AO)....

4 The long-term success of an antiretroviral regimen depends on maintaining inhibitory concentrations of active drug at the site of HIV replication sufficient to suppress viral load and prevent viral mutation and resistance. Although HIV inhibitory concentrations can be identified for antiretroviral drugs, there are persistent issues surrounding the use of drug blood concentrations to guide tre...

Wireless sensor networks (WSNs) can help the realization of low-cost power grid automation systems where multi-functional sensor nodes can be used to monitor the critical parameters of smart grid components. The WSN-based smart grid applications include but not limited to load control, power system monitoring and control, fault diagnostics, power fraud detection, demand response, and distributi...

Device specific power consumption information leads to a high potential for energy savings. Smart meters are currently deployed in several countries, but they are only able to track the overall consumption in domestic and commercial buildings. One promising option to gain device specific information is called Nonintrusive Load Monitoring (NILM), which can be of great use in combination with sma...

OBJECTIVES Kenya is one of the first African countries to scale up a national HIV viral load monitoring program. We sought to assess program scale up using the national database and identify areas for systems strengthening. METHODS Data from January 2012 to March 2016 were extracted from Kenya's national viral load database. Characteristics of 1,108,356 tests were assessed over time, includin...

Building robust network monitoring applications is hard given the unpredictable nature of network traffic and high, ever-increasing data rates. Traffic analysis systems must be designed with load shedding techniques in mind that can reduce the workload of a network monitoring system whilst gracefully degrading the accuracy of the results. We present a novel load shedding approach based on build...

Several data stream management systems (DSMSs), enabling their users to measure and analyze the behavior of a data stream on-line, are now available to the public. Network monitoring, as a challenging application domain, has shown to fit into the domain of DSMSs. With the use of the Borealis DSMS, we have implemented a set of network monitoring tasks. By performing these network monitoring task...

The performance of emerging self-organizing network (SON) algorithms is often evaluated based on simplified, regular hexagonal networks. Nevertheless, such algorithms are supposed to exploit the inherent inhomogeneity and therefore need to be tested in realistic network scenarios. For this, a common SON algorithm, namely mobility load balancing (MLB), is evaluated with different degrees of comp...

AIM To assess whether facemask utilisation by the surgeon during cataract surgery has any effect on the bacterial load falling onto the operative site. METHOD Prospective randomised masked study. Consent was obtained from 221 patients. Cases were randomised to wearing a new mask or not wearing any mask throughout the procedure. Blood agar settle plates were placed adjacent to the patient's he...
