摘要:
Provided are a route guidance system and method for emergency vehicle using telematics. The route guidance system includes an instruction station, a vehicle telematics and a traffic signal controller. The instruction station sends destination information to an emergency vehicle for dispatch due to an occurrence of an emergency circumstance. The vehicle telematics is attached to the emergency vehicle, and searches a plurality of travel routes on the basis of the destination information to provide the shortest travel route. The traffic signal controller controls a corresponding traffic signal on the travel route before the emergency vehicle approaches on the basis of travel information sent from the vehicle telematics.

A collision avoidance method and an apparatus thereof in a wireless network are provided. The collision avoidance method in the wireless network includes receiving first data from a source node, determining whether a history in which data has been previously received from the source node is present, and determining a data transmission period of the source node based on the history when the history is present, and the data transmission period is calculated when data is received from the source node. Accordingly, a collision probability can be reduced in an environment in which wireless data is periodically transmitted in a CSMA/CA manner.
摘要:
In an apparatus for identifying software components having an object and use-case information related to a model domain in a software component developing system, the object and use-case information is inputted in an input section. A UDA table creation section makes use-relation between an object and a use-case transmitted from the input section into a UDA (Use-case Data Access) table. A clustering engine creates at least one identified component by normalizing affinity values between use-relation factors in a UDA table prepared in the UDA table creation section and by performing a clustering only for a value greater than or equal to a threshold among the normalized affinity values.
