We describe the design and implementation of Open vSwitch, a multi-layer, open source virtual switch for all major hypervisor platforms. Open vSwitch was designed de novo for networking in virtual environments, resulting in major design departures from traditional software switching architectures. We detail the advanced flow classification and caching(More)
The emergence of virulent Plasmodium falciparum in Africa within the past 6000 years as a result of a cascade of changes in human behavior and mosquito transmission has recently been hypothesized. Here, we provide genetic evidence for a sudden increase in the African malaria parasite population about 10,000 years ago, followed by migration to other regions(More)
Do unsophisticated consumers fall prey to Internet consumer frauds? Why? To answer these questions this paper integrates two streams of empirical research: the process-oriented theory of deception, and the broader deception, trust, and risk (DTR) model of Internet consumer behavior. A laboratory experiment tests several alternative hypotheses about the(More)
The recovery of water loss from leaks in transmission and distribution pipes can provide a solution, at least partially, to water shortages caused by insufficient water resources and / or limited water treatment capacity. This paper introduces a new, low-cost and easy-to-use system that will help water utilities to dramatically improve the effectiveness of(More)
Commercial leak-noise correlators were generally able to locate leaks in plastic pipe, but modifications could increases their effectiveness. large percentage of water is lost in many water distribution systems in transit from the treatment plant to the consumer. According to an inquiry made in 1991 by the International Water Supply Association (IWSA), the(More)
Multifunction radars (MFRs) are sophisticated sensors with complex dynamical modes that are widely used in surveillance and tracking. Because of their agility, a new solution to the interpretation of radar signal is critical to aircraft survivability and successful mission completion. The MFRs' three main characteristics that make their signal(More)
In conventional target tracking systems, human operators use the estimated target tracks to make higher level inference of the target behaviour/intent. This paper develops syntactic filtering algorithms that assist human operators by extracting spatial patterns from target tracks to identify suspicious/anomalous spatial trajectories. The targets' spatial(More)
In this paper, adaptive sectoring of a CDMA cellular network is investigated, and the aim is to maximize the uplink capacity by utilizing mobiles spatial information. The distribution of mobiles is modeled as a spatial Poisson process, whose rate function quantizes mobiles concentration and which can be inferred with a Bayesian estimator based on network(More)
