Abstract: Flare gas is recovered by varying a number of ejector legs that depends on a flare gas flowrate. The ejector legs include ejectors piped in parallel, each ejector has a flare gas inlet and a motive fluid inlet. Flare gas and motive fluid is provided to ejectors by selectively opening or closing valves. The number of ejector legs online is varied to accommodate the amount of flare gas. The controller is also programmed to direct signals to actuators attached to the valves to open or close the valves, or to change the capacity of the ejector legs so they can handle changing flowrates of the flare gas. Included is a flare gas storage system with vessels made with flexible material, when flare gas is evacuated from the vessels, pressure in the vessels is maintained by compressing the vessels with an external force.

Abstract: A method for segmentation of a 3-D medical image uses an adaptive patient-specific atlas and an appearance model for 3-D Optical Coherence Tomography (OCT) data. For segmentation of a medical image of a retina, In order to reconstruct the 3-D patient-specific retinal atlas, a 2-D slice of the 3-D image containing the macula mid-area is segmented first. A 2-D shape prior is built using a series of co-aligned training OCT images. The shape prior is then adapted to the first order appearance and second order spatial interaction MGRF model of the image data to be segmented. Once the macula mid-area is segmented into separate retinal layers this initial slice, the segmented layers' labels and their appearances are used to segment the adjacent slices. This step is iterated until the complete 3-D medical image is segmented.

Abstract: Systems and methods for crude oil desalting technology are provided. More specifically, systems and methods for the usage of waste heat from compression to treat high salinity water are provided. The systems and methods generate recycled water streams for desalter treatment. The systems and methods can treat high salinity waters from desalters and dehydrators. The high salinity streams are introduced to the compressed gas streams, where the waste heat causes the water portion of the water streams to evaporate, resulting in a fully or near-saturated gas stream and a concentrated waste water stream. The saturated gas streams are cooled and condensed, and low TDS water is separated from the gas stream in knockout drums. The low TDS water can be reintroduced to the desalting system as wash water, generating a circular water reuse.

Abstract: A flow of a chemical is mixed with a flow of a primary fluid to form a combined fluid, and during mixing a velocity of the combined fluid is maintained at a threshold value so that a resulting mixture of the chemical and primary fluid has a designated homogeneity. The primary fluid is directed to an end of a passage with a venturi like contour that is inside of a mixer, and the chemical is directed to a side passage that extends laterally in the mixer that intersects the passage. A spring loaded valve in the passage maintains the combined flow velocity at the threshold value.

An aqueous draw stream having a second TDS level is flowed to the forward osmosis separator. The second TDS level is greater than the first TDS level. A disposal stream and an injection fluid stream is produced by the forward osmosis separator by allowing water to pass from the aqueous feed stream to the aqueous draw stream through a membrane of the forward osmosis separator based on a difference between the first TDS level and the seconds TDS level. The injection fluid stream is flowed from the osmosis separator to a subterranean formation.

Abstract: Methods, systems, and storage media are provided for user equipment (UE) that supports enhanced coverage and may operate with a voice centric usage setting or a data centric usage setting. When the UE's usage setting is set to voice centric, the UE may not operate in coverage enhancement (CE) mode B.

The UE may indicate the UE's usage setting in an Attach or Tracking Area Update (TAU) request message, and a mobility management entity (MME) may indicate to an evolved NodeB that CE mode B is restricted or not restricted based on the usage setting. Other embodiments may be described and/or claimed.

Abstract: Systems and methods of protecting an initial NAS message are described. Depending on whether a security context for a serving PLMN is stored, the UE uses either a public key from the serving PLMN or a key from the security context to encrypt parts of the initial NAS message. An initial NAS message containing the encrypted parts is then sent to an AMF of the serving PLMN. The serving PLMN public key is transmitted via a SIB. Prior to transmission of the initial NAS message or in parallel with it, an RRC message is sent to the base station. The RRC message contains the UE identifier and/or a NSSAI encrypted using the serving PLMN public key.
