System and method of integrating modules for execution on a computing device and controlling during runtime an ability of a first module to access a service provided by a second module
A system for integrating modules of computer code may include a sandbox validator for receiving a first module and verifying that the first module complies with one or more sandbox constraints. A computing device may execute the first module within a runtime environment. A module integrator may operate within the runtime environment for receiving a request from the first module to access a service provided by a second module and only allowing the first module to access the service when the first module is authorized to access the service according to a service authorization table. The sandbox validator may ensure the first module correctly identifies itself when requesting a service provide by another module and that the first module includes runtime policing functions for non-deterministic operations. A service authorizer may generate an authorization policy for the first module, which is sent to the computing device along with the first module. |

Mapping between users and machines in an enterprise security assessment sharing system
Mapping between object types in an enterprise security assessment sharing (“ESAS”) system enables attacks on an enterprise network and security incidents to be better detected and capabilities to respond to be improved. The ESAS system is distributed among endpoints incorporating different security products in the enterprise network that share a commonly-utilized communications channel. An endpoint publishes a security assessment when a potential security incident is detected. The security assessment identifies the object of interest, the type of security incident and its severity. A level of confidence in the detection is also provided which is expressed by an attribute called the “fidelity”. ESAS is configured with the capabilities to map between objects, including users and machines in the enterprise network, so that security assessments applicable to one object domain can be used to generate security assessments in another object domain. |

The present invention provides a system and method for a shared write address protocol (SWAP) that is implemented over a remote direct memory address (RDMA) connection. Each party to a connection establishes a flow control block that is accessible to its partner via a RDMA READ operation. The novel protocol operates so that each module needs to have one outstanding RDMA READ operation at a time, i.e., to obtain the current flow control information from its partner. In operation, if data to be transmitted is less than or equal to a buffer size, an INLINE message data structure of the SWAP protocol is utilized to send the data to be target. However, if the data is greater than the buffer size, a second determination is made as to whether sufficient space exists in the message pool for the data. If insufficient space exists, the sender will wait until sufficient space exists before utilizing a novel WRITE operation of the SWAP protocol to transmit the data. |

Numerical analysis method of a vehicle drive
A first analyzing step is a step that conducts numerical analysis of a flow field but does not conduct numerical analysis of a temperature field in a state in which a motor rotor is rotating. The second analyzing step is a step that conducts numerical analysis of both the flow field and the temperature field after the first analyzing step ends. Accordingly, before numerical analysis of the flow field and numerical analysis of the temperature field are conducted together, numerical analysis is conducted first on the flow field in first analyzing step before it is conducted on the temperature field. As a result, compared with when the second analyzing step is executed from the beginning without conducting the first analyzing step, the calculation load of the numerical analysis on an electronic calculator can be reduced, which enables the time that it takes to conduct the numerical analysis to be shortened. |

When the terminal has fully entered the target cell, the best carrier is selected from among the carriers available to the target cell, thus allowing the terminal to perform frequency conversion to the best carrier. |

Method and apparatus for on-line compressed sensing
A typical data acquisition system takes periodic samples of a signal, image, or other data, often at the so-called Nyquist/Shannon sampling rate of two times the data bandwidth in order to ensure that no information is lost. In applications involving wideband signals, the Nyquist/Shannon sampling rate is very high, even though the signals may have a simple underlying structure. Recent developments in mathematics and signal processing have uncovered a solution to this Nyquist/Shannon sampling rate bottlenck for signals that are sparse or compressible in some representation.

One embodiment of our invention is a low-rate analog-to-information converter that can replace the high-rate analog-to-digital converter in certain applications involving wideband signals.
