Abstract: Tracer kinetic models are utilized as temporal constraints for highly under-sampled reconstruction of DCE-MRI data. The method is flexible in handling any TK model, does not rely on tuning of regularization parameters, and in comparison to existing compressed sensing approaches, provides robust mapping of TK parameters at high under-sampling rates. In summary, the method greatly improves the robustness and ease-of-use while providing better quality of TK parameter maps than existing methods. In another embodiment, TK parameter maps are directly reconstructed from highly under-sampled DCE-MRI data. This method provides more accurate TK parameter values and higher under-sampling rates. It does not require tuning parameters and there are not additional intermediate steps. The proposed method greatly improves the robustness and ease-of-use while providing better quality of TK parameter maps than conventional indirect methods.

Abstract: A power interface (14) connected to an ultra capacitor (16), a power source (18), and a load (20), with a controller (22) for managing the power interface (14), and monitoring the ultra capacitor (16), power source (18), and demands of the load (20) attached thereto. The power interface (12) selectively switches the circuit between the ultra capacitor (16) and the power source (18), and between the load (20) in response to the level of demand of the load (20) attached thereto such that the ultra capacitor (16) powers peak demand and the power source (18) powers steady demand.

Abstract: A virtual private network implementation method includes intercepting, by an NDIS intermediate driver, a packet sent by an application program to an intranet server, and determining, according to a PID corresponding to the packet, whether to allow a process corresponding to the packet to use an SSL VPN; when the process corresponding to the packet is allowed to use the SSL VPN, establishing, by the NDIS intermediate driver, a new packet, and submitting the new packet to an NDIS network interface card driver; and sending, by the NDIS network interface card driver, the new packet to the client, and sending, by the client, the new packet to the intranet server. Thereby, a virtual private network is implemented based on process control, and a client has a fast startup speed.

Abstract: The embodiments of the present invention provide a method for processing data visualization information, the method includes: analyzing whether a input information received is recognized; converting the input information that can be recognized into media information with a specified presentation form; determining, based on confirmation information of the media information, whether the input information is recognized correctly. When the input information is recognized correctly, determining based on a recognition result of the input information, a set of keywords. Determining, based on the set of keywords, an interactive instruction corresponding to the recognition result, and then executing the interactive instruction. By implementing the method of the embodiments of the present invention, the interaction between the user and the data display can be improved in the data visualization scenario, and the monotony of the current data visualization interaction mode can be broken up.
