Simultaneous Dynamical Integration modeling techniques are applied to global placement of elements of integrated circuits as described by netlists specifying interconnection of morphable-devices. Solutions to a system of coupled ordinary differential equations in accordance with Newtonian mechanics are approximated by numerical integration. A resultant time-evolving system of nodes moves through a continuous location space in continuous time, and is used to derive placements of the morphable-devices having one-to-one correspondences with the nodes. Nodes under the influence of net attractive forces, computed based on the interconnections between the morphable devices, tend to coalesce into well-organized topologies. Nodes are also affected by spreading forces determined by density fields that are developed based on local spatial node populations.

The embodiment of the invention discloses a data transmission method during switching used in a LTE system comprising a mobile management entity MME/user plane entity UPE, a source development base station eNodeB and a terminal. The method comprises the following steps: when the LTE system is under switching, the source eNodeB notifies the MME/UPE to temporarily stop transmitting data packet to the source eNodeB after sending a switching command to the terminal; the MME/UPE, after receiving the pause notification, completes buffer storing of data packet failed to be transmitted to the source eNodeB; finally, when switching is completed, the data packet stored in the MME/UPE is transmitted to the terminal. Thus, the data transmission method reduces service delay and improves service quality during switching. In addition, the embodiment of the invention also discloses an LTE system and user plane equipment.

The invention relates to a secure use method of privacy data in cloud computation. The secure use method is characterized by comprising the basic steps of classification of the privacy data of a user, detection of an exposed chain and the key privacy data, protection of the discrete privacy data and protection of the continuous privacy data. Through detection of the exposed chain and the key privacy data in the first stage and recombination with the exposed chain and the key privacy data as root nodes in the second stage, the continuous privacy data are converted into the discrete privacy data, and then personal privacy information of the user is protected. The requirement of the user is met through decomposition and combination of the privacy data without exposing a discrete privacy data chain of the sensitive privacy information of the user, and therefore the method can effectively guarantee the secure use of the privacy information of the user in a multiparty interactive sharing and evolving system.

The invention provides a method for collocating tracking regions and a device thereof, which is used for an evolved system of the mobile communication PS domain including a mobile management entity and an evolved node. The method comprises that the evolved node sends a connection establishment request to the mobile management entity; the connection establishment request carries one or more tracing region marks corresponding to one or more tracing regions assigned to the evolved node; responding to the connection establishment request, the mobile management entity acquires one or more tracing region marks; under the condition that one or more tracing region marks can not be searched, collocation is carried out for one or more tracing regions corresponding to one or more tracing region marks. The collocation is directly carried out by the mobile management entity of the evolved system of the mobile communication PS domain for the tracing regions so that the number of the tracing regions in the evolved system of the mobile communication PS domain is increased and the requirement for tracing regions in the evolved system of the mobile communication PS domain is met.

This disclosure shows how a time series of measurements of an evolving system can be processed to create an “inner” time series that is unaffected by any instantaneous invertible, possibly nonlinear transformation of the measurements. An inner time series contains information that does not depend on the nature of the sensors, which the observer chose to monitor the system. Instead, it encodes information that is intrinsic to the evolution of the observed system. Because of its sensor-independence, an inner time series may produce fewer false negatives when it is used to detect events in the presence of sensor drift. Furthermore, if the observed physical system is comprised of non-interacting subsystems, its inner time series is separable; i.e., it consists of a collection of time series, each one being the inner time series of an isolated subsystem. Because of this property, an inner time series can be used to detect a specific behavior of one of the independent subsystems without using blind source separation to disentangle that subsystem from the others. The method is illustrated by applying it to: 1) an analytic example; 2) the audio waveform of one speaker; 3) mixtures of audio waveforms of two speakers.
