  • Publication number: 20140115706
    Abstract: A shadow network, which can be a virtual reproduction of a real, physical, base computer network, is described. Shadow networks duplicate the topology, services, host, and network traffic of the base network using shadow hosts, which are low interaction, minimal-resource-using host emulators. The shadow networks are connected to the base network through virtual switches, etc. in order to form a large obfuscated network. When a hacker probes into a host emulator, a more resource-intensive virtual machine can be swapped in to take its place. When a connection is attempted from a host emulator to a physical computer, the a host emulator can step in to take the place of the physical computer, and software defined networking (SDN) can prevent collisions between the duplicated IP addresses. Replicating the shadow networks within the network introduces problems for hackers and allows a system administrator easier ways to identify intrusions.

  • Publication number: 20130073488
    Abstract: Techniques for evaluating the accuracy of a predicted effectiveness of an improvement to an infrastructure include collecting data, representative of at least one pre-defined metric, from the infrastructure during first and second time periods corresponding to before and after a change has been implemented, respectively. A machine learning system can receive compiled data representative of the first time period and generate corresponding machine learning data. A machine learning results evaluator can empirically analyze the generated machine learning data. An implementer can implement the change to the infrastructure based at least in part on the data from a machine learning data outputer. A system performance improvement evaluator can compare the compiled data representative of the first time period to that of the second time period to determine a difference, if any, and compare the difference, if any, to a prediction based on the generated machine learning data.

  • Publication number: 20110007775
    Abstract: The differential adiabatic compensation calorimeter comprises sample and reference containers, sample and reference temperature sensors connected back-to-back, in series, sample and reference compensating heaters coupled to the sample and reference containers, and a temperature-controlled chamber. In this differential adiabatic mixing and reaction calorimeter, the sample heat-sink heat loss to the sample container is compensated so that the exothermic reaction is conducted in an adiabatic state, resulting in an undistorted adiabatic process gaining the highest adiabatic temperature rise that corresponds to the theoretical value and an experimentally measured time to maximum rate value. The calorimeter is designed for measuring the time-resolved adiabatic temperature rise, the rate of temperature rise, the time to maximum temperature peak and time to maximum rate of an exothermic chemical reaction.
