The apparatus for controlling an inverter is disclosed which detects a rotation angle of a load using a current supplied to the load when the inverter utilizes a voltage/frequency control to control the driving of the load, and accurately drives the load using the detected rotation angle, where the current supplied to the load by the inverter is detected by a current sensor, and a rotation speed of the load is estimated by the detected current to be used for the driving of the load.

Apparatus for controlling inverter

Provided is a root mobile router and the operating method thereof in a dynamically composed moving network, capable of forming a self-configuring ad-hoc network between wireless personal area networks (WPANs) of each user in a moving network and supporting a stable connection between the network and the Internet. The method includes the steps of: receiving state information of multiple access networks and selecting an optimal access network in order to connect to the Internet; receiving a result of the selection and activating an interface of the selected access network; changing the selected access network to the activated access network interface; and updating routing path information automatically and stably transmitting an IP packet to the Internet through the selected access network interface. Therefore, a personal mobile terminal can be utilized as a mobile router.

A transmission apparatus having a plurality of network interfaces and a transmission method using a plurality of the network interfaces are provided. The transmission apparatus includes: a session information extraction unit which extracts session information of an IP packet; a network interface determination unit which determines a network interface associated with session information of the IP packet based on a table for mapping sessions to the network interfaces according to available bandwidths of the network interfaces; and a traffic distribution unit which transmits the IP packet to the determined network interface. Accordingly, traffic is distributed over a plurality of network interfaces, so that optimal communication performance can be ensured in a simultaneous multiple-mode connection environment, and network resources can be efficiently utilized.

Transmission apparatus having a plurality of network interfaces and transmission method using the same

A Linux kernel and an application software package are integrally installed at a target computer by using a CML2. Setup options of the application S/W package to be installed at the target computer are described in an option information file. The option information file of the application S/W package is converted into a CML2 rule file and the CML2 rule file of the application S/W package is then integrated with a CML2 rule file of the Linux kernel, thereby realizing integrated configuration of the Linux kernel and the application S/W package and preparing an environment where dependency rules between the Linux kernel and the application S/W package can be described. Since every option in the option information file has a file list and these file lists are stored in a file list table, an installation file list that describes files finally installed at the target computer can be easily generated.

Method for integrating Linux kernel and application software packages and generating installation file list based on CML2 computer language

A method for connecting precast concrete girders by tensioning temporary tendons lower than the neutral axes of girders, supporting the girders at the both ends, placing concrete into the gap, tensioning the tendons which connect adjacent girders while releasing the temporary tendons in order to reduce the bending moment at the midspan of girders.

Method for connecting precast concrete girders

A connection method for connecting precast concrete beams involves supporting both ends of the precast concrete beams, lifting up the central points of the precast concrete beams, placing concrete in the gaps between the ends of the precast concrete beams, and positioning tendons through anchor blocks which project from the precast concrete beams. The tendons are then tensioned and, substantially simultaneously, the lifting forces applied to the concrete beams are reduced. The connection method reduces the bending moment caused by the self-weight of precast concrete beams and, as a result, reduces the size of the beam section.
