Title: Methods and systems that attenuate noise in seismic data
Inventor: STIAN HEGNA
IPC: G01V1/48
Filed: 2015-10-15
Abstract: A system and method used to attenuate noise in seismic data. A sparse seismic-data matrix is generated 1604 from received seismic data 1601. The sparse seismic data matrix is then transformed from a space-time domain to a transformation domain to generate a spectrum 1605. A signal region of the spectrum is then determined 1606 before muting certain amplitudes in the signal region to generate a partial noise spectrum 1607 of the spectrum. A low-speed noise model based on the partial noise spectrum is then iteratively determined 1608. The low-speed noise model includes noise that propagates at speeds less than the speed of sound in water and also interpolated low-speed noise that represents noise affected by spatial aliasing and streamer irregularities. The low-speed noise model is then subtracted from the sparse seismic-data matrix to generate a noise-attenuated sparse seismic-data matrix 1609.

Title: Methods and systems for enhancing control of power plant generating units
Inventor: LISA ANNE WICHMANN
IPC: G06Q50/06
Filed: 2015-11-25
Abstract: Optimal control of a power plant comprises comparing 730 the calculated economic outcomes of a proposed turndown operating sequence or mode 710 with the calculated economic outcome of a proposed shutdown sequence 719. The calculation is performed over a time interval, each mode representing generating units operating in a given combination of on or off conditions, and a preferred sequence comprising multiple time intervals may be determined for optimal control of the plant over a period, for example a future off-peak period, for optimal ordering of fuel or for calculating a bid for the period for a dispatch system. Limitations such as safety and emissions regulations may be taken into account and simulations of generator operation may include manually input or sensed parameters, such as degradation of the units, ambient conditions, different types of generator, start-up and shut-down costs and times, minimising fuel consumption and the like. Models may be adjusted or calibrated in real time, and neural networks may be employed. The generating units may be individual generators, or different plants in a power grid. The output 731 may be delivered to an operator, or may be used to automatically control operation of the plant.

The display may comprise of inorganic light emitting diode devices LEDs, and may form an active matrix LED display comprising active selection devices (see figures 7a-b). The PWM/pulse driver signals may connect to the drain of a pixel cell amplifier transistor T2 (fig 7a) or to the LED cathode (figure 7b), for improved power efficiency.

Filed: 2016-06-17
Abstract: A method of controlling operation of a fuel injected piston combustion engine having a valved exhaust gas recirculation path between an exhaust and an intake; exhaust gas treatment apparatus modules receive exhaust gas. The method comprises injecting fuel into combustion cylinders in a primary combustion injection event and operating in first and second modes with respective durations for increasing exhaust gas temperature to respectively first and second temperatures, T1 and T2, where T1, > T2. In the first mode the exhaust gas recirculation valve is closed and a delay of at least 50 times the first mode duration is invoked between first mode operations. The second mode has a shorter duration than the first. Both modes involve periodically injecting fuel at respective first and second injection rates in respective subsidiary injection events when fuel passes into the exhaust for combustion therein to raise temperature in the treatment apparatus. The first mode is invoked to target T1 and the second mode is invoked to target T2.

Title: Mitigation of return-oriented programming attacks
Inventor: Erik Loman
IPC: G06F21/55
Filed: 2017-08-03
Abstract: A method of mitigating trampoline based attacks and return-oriented programming attacks comprises providing a computer executing an operating system with a user space and a system space. When a call is made from a process executing in the user space to a kernel executing in the system space, the call is detoured 804 to e.g. a stub, which carries out a security process. The security process involves determining 806 a predicted return address and a predicted ordinal for the call. These are then compared to an actual return address and ordinal of the call, and if there is a mismatch, a possible return oriented programming attack is detected. The security process may further involve providing a branch prediction and comparing it to a taken branch, and if there is a discrepancy, detecting a possible return-oriented programming attack.
