In accordance with some implementations, a method for evaluating large scale computer systems based on performance is disclosed. A large scale, distributed memory computer system receives topology data, wherein the topology data describes the connections between the plurality of switches and lists the nodes associated with each switch. Based on the received topology data, the system performs a data transfer test for each of the pair of switches. The test includes transferring data between a plurality of nodes and determining a respective overall test result value reflecting overall performance of a respective pair of switches for a plurality of component tests. The system determines that the pair of switches meets minimum performance standards by comparing the overall test result value against an acceptable test value. If the overall test result value does not meet the minimum performance standards, the system reports the respective pair of switches as underperforming.

Disclosed are arrangements for selling property off the plan, involving issuing (in a step ‘8’ in FIG. 6) an undertaking from a bank of a purchaser in favour of the developer from whom the property is to be purchased. The undertaking may be assigned (in a step ‘12’ in FIG. 6) to the developer's bank. The undertaking is legally enforceable by the assignee (in a step ‘15′’ in FIG. 6) if the purchaser, notwithstanding the fact that the developer has completely fulfilled the contractual obligations, defaults on his obligation at settlement.

An image without use of a flash is taken, along with an image using a flash. A difference image is generated by subtracting the flash-less image from the flash image. A threshold is applied to the difference image such that only large differences in intensity remain in the difference image. This artifact image is then subtracted from the flash image, thereby removing flash artifacts such as specular reflections and red-eye. The threshold used may be automatically calculated or may be set by the user. For some applications it may be desirable to set separate thresholds for each dimension of the color space (such as red, green, and blue) used. Once again these separate thresholds may be automatically calculated or may be set by the user.

In a flow metering apparatus a bubble detector for detecting bubble formation in tubing subject to deformation from internal fluid pressure includes a light source and a light detector. The light detector is positioned on the opposite side of the tubing from the light source such that the light transmitted through the tubing to the detector is dependent on the presence of fluid in the tubing and on the shape of the lumen of the tubing. A control circuit responsive to the output of the detector interrupts operation of the metering apparatus when the light transmitted through the tubing falls below a predetermined minimum level. False interruptions resulting from deformation of the tubing by pressure changes in the fluid are prevented by forming members which engage the wall of the tubing adjacent the light source and light detector.

A mixing device of the type having a housing of generally cylindrical construction, having an end wall with concentric arrays of axially extending mixing elements thereon, a rotor being rotatable within the housing and having on the face thereof further axially extending mixing elements in a plurality of annular concentric arrays, the mixing elements of the rotor and housing interfitting with one another. The mixing elements themselves are each defined by inner and outer part-cylindrical surfaces and by further straight surfaces forming the sides of grooves, the axes of the grooves being disposed along different tangents to an inner pitch circle which is concentric with the part-cylindrical surfaces. This provides a much better mixing effect and produces a certain reverse pumping within the mixer. These features enable the mixing elements to be made shorter with the possibility of the rotors and end walls of the housing being formed by moulding.

A mounting system for supporting a power system is disclosed. The mounting system may have a support structure including a first end spaced from a second end of the support structure. The mounting system may further have a first mounting assembly attached near the first end of the support structure. The first mounting assembly may have a first mounting support and a second mounting support for supporting the support structure, each of the first mounting support and the second mounting support attached to the support structure offset to a side of a longitudinal axis. The mounting system may also have a second mounting assembly attached near the second end of the support structure. The second mounting assembly may have a third mounting support attached to the support structure below the longitudinal axis for supporting the support structure. The second mounting assembly may have at least one shock absorber mounted near the third mounting support.

A gas turbine engine system includes a gas turbine engine using vaporized liquefied gas as fuel. The gas turbine engine is configured to ingest intake air from an intake port and direct exhaust gases to an exhaust port. The gas turbine engine system also includes a heat exchanger with a heat transfer fluid therein. The heat exchanger is configured to create at least a part of the fuel by heating the liquefied gas. The gas turbine engine system also includes an intake air temperature control circuit. The intake air temperature control circuit includes conduits configured to direct the heat transfer fluid to the intake port and the exhaust port. The gas turbine engine system also includes a control system configured to selectively direct the heat transfer fluid to one of the intake port and the exhaust port.
