If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.

A fire growth and smoke movement model for a multi-compartment building has been developed at the National Research Council of Canada. This development is primarily intended to help evaluate the risk from fires in buildings.
This paper presents the related physical models, numerical methods, and some verification examples. The four independent variables for one compartment are selected as pressure, enthalpy of upper layer, and mass of upper and lower layers. The implemented fire sub-models are introduced, including combustion, fluid flow and heat transfer models. For each compartment without smoke or fire, a non-linear algebraic equation based on mass conservation is used instead of the ODEs. The numerical solution of the governing equations is obtained using a room by room iteration method.
In this algorithm, an existing ODE solver, LSODA, has been modified and used to solve the stiff ODEs, and the Steffensen Acceleration Method is used to solve the algebraic equations. Experimental data for single- and two-compartment fire tests are compared to the predictions of the model. The comparison shows favourable results, especially for the upper layer gas temperature, interface height, and vent flow rate.

An assistive navigation prototype is proposed. Sole input is low resolution images from wearable or mobile device cameras. Position is inferred by matching footage between users. Uses a novel electrostatic haptic feedback technology to convey positions on a map.
Benchmarking of localisation method and haptic feedback quality is provided. Computer vision remains an under-exploited technology for assistive devices. Here, we propose a navigation technique using low-resolution images from wearable or hand-held cameras to identify landmarks that are indicative of a user’s position along crowdsourced paths. We test the components of a system that is able to provide blindfolded users with information about location via tactile feedback. We assess the accuracy of vision-based localisation by making comparisons with estimates of location derived from both a recent SLAM-based algorithm and from indoor surveying equipment.
Finally, we describe a relatively lightweight systems architecture that enables images to be captured and location results to be served back to the haptic device based on journey information from multiple users and devices.

The excited reporter plants his hands on the editor’s desk and leans in, eyes wide. And not just from the feds but from all the state governments, too! And they’ve been doing it for almost 15 years! IS THE STORY OF THE CENTURY! But son, think about it.
I’d have heard about it. The reporter lets his own mouth twitch now, in turn. Chief, of course that’s just what you’d think. And that’s part of the story, Chief! That’s exactly what EVERYONE has thought.
