A simple yet effective and robust identification method is presented using process step responses for process identification that can provide a continuous transfer function with time-delay without iteration. A cascade relay provides accurate and reliable more points on the process frequency response. The internal model principle is employed to design single-loop controller of PID or high-order types with best achievable control performance for controller tuning, e.g. both single and multivariable cases are covered. The process identification and control design portions can be easily integrated into a control system auto-tuning package. Further, a general control scheme for disturbance rejection is given which can significantly improve disturbance rejection performance over conventional feedback systems with time delays. Practical issues such as noises, real-time implementation and tuning guidelines are also provided. The present invention provide general, systematic, effective, and applicable methods for process identification and control for a wide range of industries such as process and chemical plants, food processing, waste water treatment and environmental systems, oil refinery, servo and mechatronic systems, where a system model is needed for analysis, prediction, filtering, optimization and management, and / or where control or better control is required for their systems.

This invention provides a novel process identification and control package for high performance. For process identification, a simple yet effective and robust identification method is presented using process step responses to give a continuous transfer function with time-delay without iteration. A new relay, called cascade relay, is devised to get more accurate and reliable points on the process frequency response. For controller tuning, the internal model principle is employed to design single-loop controller PID or high-order types with best achievable control performance. The process identification and control design parts can be easily integrated into control system auto-tuning package. Further, a general control scheme for disturbance rejection is given which can significantly improve disturbance rejection performance over conventional feedback systems with time delays. Practical issues such as noises, real-time implementation and tuning guidelines are also provided. The invention covers both open-loop and closed-loop testing, and single and multivariable cases.

The invention discloses a method and device for managing application program processes. The method includes: a receiving system broadcasts a message to determine whether the screen of a terminal is closed or not; when the screen is closed, the process identification of each application program is traversed through an application program calling interface so as to find the process importance index of each application process, and the process priority of each application program is determined according to the process importance index; the processes with low priority are closed or set into a sleep state according to preset process managing rules. The method has the advantages that the processes with low priority are closed or set into the sleep state according to the priority of the processes, the processes with low priority are set into sleep preferably after screen locking, and accordingly internal memory space is saved, and power consumption is reduced.

A method for accessing a protected file system includes receiving a request from a process to access the file system, the request including a requesting process identification and a requesting process name; decrypting an ACL to obtain ACL process names, ACL process identifications, and ACL process file checksums; allowing the process access to the file system if the requesting process name matches a corresponding ACL process name and the requesting process identification matches a corresponding ACL process identification; or allowing the process access to the file system if the requesting process identification does not match a corresponding ACL process identification but a calculated process file checksum matches a corresponding ACL process file checksum. In one embodiment, the ACL information can be stored in a key ring.

The invention belongs to the field of load power use monitoring and energy management, and particularly relates to a method and system for identifying transient process of a non-intrusive load. The method comprises the following steps: by virtue of transient power waveform characteristics of multiple types, measuring similarity of a transient power waveform characteristic parameter sample sequence of an unfixed length and a template sequence by using a dynamic time warping algorithm within a time domain, on the basis, establishing a load transient process classification identification scheme based on a nearest neighbor classification strategy, and confirming power use equipment with the load transient process, thereby achieving artificial working state identification on the non-intrusive type power use equipment. The method and the system have the beneficial effects that accuracy and robustness of power load transient process identification can be improved, the cost of a monitoring system can be effectively controlled, and the practicability of the monitoring system can be effectively improved, therefore, practical popularization of an NILM (Non-Intrusive Load monitoring) technique can be greatly improved.

An online identification document management service includes a host server having a web-based interface adapted to facilitate secure customer access to the host server. The host server is configured to receive identification data communicated from the customer through use of a computing device. The identification data includes at least one of an imaged identification document and information related to the imaged identification document. A processing module is in operative communication with the host server and is configured to process the identification data communicated from the customer. A processing software application is trained to classify the processed identification data and selectively extract data therefrom based on the classification. The processing software application is configured to selectively present the processed identification data for a customer verification via the web-based interface upon at least one of an unsuccessful classification and an unsuccessful extraction of data. A storage device is in operative communication with the processing module and is configured to store the extracted data as metadata upon at least one of the customer verification and the extraction of data. The processing software application is cumulatively trained to subsequently classify the processed identification data successfully upon the customer verification thereof. A content management software application operates on the host server and is configured to process a customer request through the web-based interface to selectively generate at least one reproduction of the processed identification data.
