Abstract: Arrangements for steganography-based security document access control are provided. In some examples, a security policy for a document may be generated. The security policy may include identification of one or more users authorized to access the document and one or more response actions to execute upon violation of the security policy. The generated security policy may be embedded in the document using steganography. Accordingly, transmission of the document may include transmission of the security policy with the document. The document may be transmitted to a destination node. A user at the destination node may request access to the document. In response to the request, the security policy embedded in the document may be executed to confirm whether the user is an authorized user. If the user is authorized, access to the document may be enabled. If the user is not authorized, the one or more response actions may be executed.

Abstract: A method comprises receiving active data of a number of time series datasets for different attributes of an active drilling operation of an active well, for a previous time period having a defined length of time and retrieving historic data, that corresponds to the active data, of the number of attributes for offset drilling operations of a number of selected reference wells. The method includes selecting a subset of the historic data that satisfies a relevancy threshold based on relevancy to the active data, wherein the selecting is based on similarities between the number of time series datasets in the active data and the historic data. The method includes creating a predictive composite logging, for a future time period, that includes a number of predictive times series datasets for at least a portion of the different attributes based on the selected subset of the historic data.

Abstract: Aspects of the disclosure are directed to methods and/or apparatuses involving modifying flow and/or concentration of an agent being injected for characterizing a vascular system. As may be implemented in accordance with one or more embodiments, a liquid including an agent is injected into a vascular system, by dynamically modulating a flow rate of the agent being injected over a range of flow rates. The vascular system is characterized based on a response of the vascular system to the dynamic modulation. In some implementations, such an approach involves using an injector that operates to separately control the rate at which an agent and other liquid such as saline are injected. These approaches can be implemented with modulation schemes using one or more of a variety of functions.

Abstract: The present invention provides a novel apparatus and method for the gasification of liquid petroleum fuel (gasoline), that has been atomized and emulsified with atmospheric air, by implementing a multi-Stage Heat Exchanger System. The first stage employs a spigot mounted carburetor or fuel injection unit, positioned in a straight line laminar flow path, flowing into an exhaust gas heated “Shell and Tube” style heat exchanger unit. In the second stage, the already heated gasoline vapor mixture then flows into an attached compressor housing inlet of a “Draw through Turbine Heat Exchanger Compressor” component, which through an impeller means, further heats and compresses the vaporous air and gasoline mixture. The third stage, utilizes an “Exhaust Gas Heat Exchanger Coil” or alternative “Heat Exchanger Sphere”, which is fitted internally, into conduction heated metal open plenum style intake manifold.
