A radiation therapy treatment method includes providing a patient model, dosimetric constraints, delivery motion constraints, and delivery coordinate space of a radiation delivery device, where the delivery coordinate space is represented as a mesh with vertices connected by edges, where the vertices correspond to directions of a beam eye view (BEV) of the radiation delivery device, where each BEV has corresponding area elements resulting from beam collimation. BEV region connectivity manifolds are constructed from the patient model, the dosimetric constraints, the delivery coordinate space, and existing beam trajectories, wherein each of the BEV region connectivity manifolds represents connections between contiguous 2D target regions, where each of the 2D target regions is defined at each of the vertices of the delivery coordinate space. Beam trajectories are selected based on region connectedness information in the BEV region connectivity manifolds, the dosimetric constraints, the delivery motion constraints, and the existing beam trajectories. Radiation is delivered using the radiation delivery device in accordance with the beam trajectories.

The invention discloses a thread-scheduling method applied to symmetrical multi-processor systems, and a device thereof. The method comprises the following steps: a thread-scheduling request is received, an executory thread in a ready state is selected, a thread associated with the executory thread is obtained, and the executory thread which is in the ready state in the obtained thread is set to a non-ready state; the selected executory thread is assigned to the processor which sends out a scheduling request for executing, and the thread which is set to the non-ready state and the thread associated with the selected thread are restored to the ready states when the selected thread executing is finished. By adopting the method, the contesting and the simultaneous resource expenses brought by free scheduling of the symmetrical multi-processor systems to the thread can be reduced, the phenomena that the system efficiency is low because the thread is designated to the fixed processor for execution can be avoided, and the operating efficiency of the system can be improved.

The invention discloses a broadcasting method based on distance and energy balance in a mobile Ad Hoc network. A node obtains information of neighbor nodes according to groupings received from the neighbor nodes, determines the distance between itself and the neighbor nodes, and builds or updates a neighbor information table; forwarding priorities are determined according to the distance between the node and the neighbor nodes and the residual energy of the node, the node carries out time-sharing forwarding according to the forwarding priorities, and channel competition and grouping collision are reduced. A lost packet retransmission mechanism is included in the method, whether broadcasting groupings are sent successfully or not is judged according to the fact whether the same broadcasting grouping forwarded by the neighbor nodes is received or not, and the broadcasting reliability is further improved. The method can well restrain the broadcasting storm, and the broadcasting reliability is improved; meanwhile, the time delay is small, and the requirement of QoS application can be better met; the method can further balance the energy consumption of the nodes in the network better, and the service life of the network is prolonged.

The invention discloses a broadcasting method in a mobile Ad Hoc network based on the node broadcasting success rate and energy balance. The broadcast transmitting probability is determined according to the node broadcasting success rate and remaining energy. The higher the node broadcasting success rate is, the higher the reliability of node transmitting broadcast grouping is, therefore, high transmitting probability is given to the node, collision can be reduced, the reliability can be improved, and broadcast storms can be inhibited. Meanwhile, if the more the remaining energy of the node is, the larger the transmitting probability of the node is, the remaining energy serves as the factor determining the transmitting probability, the energy consumption of the network node can be balanced, and the network lifetime can be prolonged.
