Method and system for optimization of geneal symbolically expressed problems, for continuous repair of state functions, including state functions derived from solutions to computational optimization, for generalized control of computational processes, and for hierarchical meta-control and construction of computational processes

Methods and systems for finding optimal or near optimal solutions for generic optimization problems by an approach to minimizing functions over high-dimensional domains that mathematically model the optimization problems. Embodiments of the disclosed invention receive a mathematical description of a system, in symbolic form, that includes decision variables of various types, including real-number-valued, integer-valued, and Boolean-valued decision variables, and that may also include a variety of constraints on the values of the decision variables, including inequality and equality constraints. The objective function and constraints are incorporated into a global objective function. The global objective function is transformed into a system of differential equations in terms of continuous variables and parameters, so that polynomial-time methods for solving differential equations can be applied to calculate near-optimal solutions for the global objective function. Embodiments of the present invention also provide for distribution and decomposition of global-gradient-descent- field-based optimization methods, by following multiple trajectories, and local-gradient- descent-field-based optimization methods, by using multiple agents, in order to allow for parallel computation and increased computational efficiency. Various embodiments of the present invention further include approaches for relatively continuous adjustment of solutions to optimization problems in time, to respond to various events, changes in priorities, and changes in forecasts, without needing to continuously recalculate optimization solutions de novo. While many embodiments of the present invention are specifically directed to various classes of optimization problems, other embodiments of the present invention provide a more general approach for constructing complex hierarchical computational processes and for optimally or near optimally controlling general computational processes.

Method for operating multiple applications of intelligent television synchronously

The invention relates to an intelligent television. Aiming at the problem that the intelligent television only can run one task at the same time, a method for operating multiple applications of the intelligent television synchronously is provided. The method comprises the steps that: when the intelligent television runs more than one task currently, a system detects operating information of a current user, and if a multi-task synchronous running command sent out by the user is detected, the system suspends all the current tasks on the screen via a form of thumbnail windows; otherwise, the system carries on detecting the operating information of the user and performs split-screen playing on all the tasks; meanwhile, the system judges the priority of audio data of all the tasks and plays the audio data with highest playing priority; when the priorities of the audio data of the tasks are judged to be same by the system, the system plays the audio data of the task which is opened later. Therefore, the user can operate the multiple applications of the intelligent television synchronously and conveniently. The user is enabled to operate the task synchronously and more flexibly, and the time utilization rate is improved fully. The invention is suitable for a same-screen real-time operating method of multiple applications of the intelligent television.

Multi-mode tuning method for medical cyclotrons

ActiveCN102984878AImprove machine time utilization efficiencyFull coverage and convenienceMagnetic resonance acceleratorsAnalogue switchPhase locking
The invention belongs to the technical field of accelerators, and discloses a multi-mode tuning method for medical cyclotrons. The method comprises that after a radio frequency system is started and turned into a continuous running state, a phase locking loop (PLL) tracking cavity resonant frequency mode is used for tuning, and a fine tuning capacitance plate is placed in the middle of an adjustment stroke; when PLL frequency update tuning operates for 5 minutes to 10 minutes, a digital signal processor controls to switch an analogue switch, the fine tuning capacitance plate is converted from position feedback to capacitance plate tuning, and simultaneously, the PLL uses a current frequency value as a starting point and a final working frequency value as an ending point, and the frequency is reduced to working frequency and fixed in a mode with 0.002 MHz of stepping and an interval of 1s; and capacitance plate position signals are monitored continuously, a stroke intermediate point serves as a reference, protection points are arranged at 4/5 positions on the left and right, and the capacitance plate is fixed after being adjusted by the PLL when surpassing the positions. According to the multi-mode tuning method for medical cyclotrons, a whole process of radio frequency starting and running can be covered completely and conveniently, and the whole machine time utilization efficiency is improved.

Method and system for calibration of a radio direction finder

A calibration method and a system for providing calibration data for use with a direction finder are provided. The method comprises providing a relative motion of a calibration receiver in a circle manner with respect to calibration transmitter at a predetermined distance from each other. The method also includes preparing and transmitting a communication frequency signal employed for transmitting a certain frequency from a list of predetermined frequencies. The preparing comprises: (a) setting a value of the dwell time ranges of the communication frequency signal to a predetermined value; (b) synchronizing in time the dwell time ranges between the calibration transmitter and the calibration receiver by using clock signals of a common synchronization source; (c) providing a hop duration time interval within the dwell time range for transmitting the frequency; and (d) generating the communication frequency signal corresponding to the frequency during the hop duration interval. At the calibration receiver end, the method includes scanning the list of predetermined frequencies; intercepting a frequency signal transmitted during the hop duration time interval within the dwell time ranges; and rejecting all other frequency signals received within the dwell time ranges having duration different than the hop duration time interval by the receiver.
