    Abstract: A disclosed system, method and computer readable storage medium includes mechanism for controlling cascade price movements in an electronic trading system. Price limits control the prices at which traders can place orders. An upper price limit prevents traders from placing orders above the upper limit and a lower price limit prevents traders from placing orders below the lower limit. The gap between the upper limit and the indicative market price as well as the gap between lower limit and the indicative market price is controlled so as to cause a breaking effect on very rapidly changing market price.

    Abstract: When multiple motors (40) share a common DC power supply (10) via a bus (20), a system and method is provided for managing the effect of regenerative energy caused by a motor. The regenerative energy may be sensed, e.g., by a power electronics controller (50, 50′). In response, one or more of the other motors currently in operation may be controlled to operate according to a reduced power factor. Thus, the excess energy is consumed without adding any new components or increasing the amount of work performed in the system.

    Abstract translation: 当多个电动机(40)经由总线(20)共享公共直流电源(10)时,提供了一种用于管理由电动机引起的再生能量的影响的系统和方法。 可以例如通过电力电子控制器(50,50')感测再生能量。 作为响应,可以控制当前正在运行的一个或多个其他电动机以根据降低的功率因数进行操作。 因此,在不添加任何新组件或增加在系统中执行的工作量的情况下消耗多余的能量。

    Abstract: A Model Predictive Control System, particularly useful in controlling gas turbine engines, formulates a problem of controlling the engine to achieve a desired dynamic response as a solution to a quadratic programming problem. The Model Predictive Control System also includes a quadratic programming problem solver solving the quadratic programming problem in real time using an interior point algorithm that searches for an optimal solution.

    Abstract: An efficient method for solving a model predictive control problem is described. A large sparse matrix equation is formed based upon the model predictive control problem. The square root of H, Hr, is then formed directly, without first forming H. A square root (LSMroot) of a large sparse matrix of the large sparse matrix equation is then formed using Hr in each of a plurality of iterations of a quadratic programming solver, without first forming the large sparse matrix and without recalculating Hr in each of the plurality of iterations. The solution of the large sparse matrix equation is completed based upon LSMroot.

    Abstract: A venting system for venting a gaseous fluid from a tank having an aperture and a fuel delivery module cover. The tank is made of a predetermined material. The venting system comprises a venting valve disposed within the aperture. The venting valve includes a valve body having a top portion and a neck portion extending from the top portion. The top portion is disposed outside the tank and is engaged thereto. The venting system further includes a channel which connects to the valve body so that the venting valve is in fluid communication therewith and is attached to the fuel delivery module cover to allow the gaseous fluid in the tank to be vented therefrom. The venting system further includes a cover which is comprised of the same predetermined material and is welded to the tank to seal the valve between the cover and the tank.
