Abstract: This server for distributing messages quickly detects a performance decline in a downstream server by using a method for keeping, for each distribution-destination server, a threshold such as a connection number and a time interval separate from a response timeout, and determining that performance has declined when the threshold is exceeded. In addition, the present invention improves system availability by identifying a server group in which performance has declined on the basis of a correlation pertaining to inter-server cooperative processing, when a distribution server exhibits a decline in performance, and by the distribution server distributing a message to a server not exhibiting a decline in performance.

Abstract: In a mail gateway, a collection part collects, for each specific information contained in a mail entered into a resending queue, statistical information of the specific information. A provisional queue creation part creates a provisional queue based on the collected number of the statistical information. The provisional queue handles a mail which has a possibility of causing congestion. This can prevent a normal queue from entering into a congestion state. Also in the mail gateway, if the congestion state is brought about in the provisional queue which performs a send of a mail containing the specific information, a mail sort part restricts an entry of a mail into the provisional queue. This can limit an influence of the congestion state only to the provisional queue.

A dedicated device for obtaining the heartbeat or breathing beat such as ECG and a respiratory measuring device is not required, and a heartbeat signal and a breathing beat signal can be obtained from an ROI signal of the projection data. As a result, blurring on an image caused by the heartbeat can be eliminated, and an image quality is extremely improved.

Abstract: To solve the problem with mobile phone carriers that increasing mail traffic increases storage capacity of a mail server and network load, a relay server which relays a mail transfer (SMTP communication) and a mail fetch (IMAP communication) is installed in a carrier facility network. The relay server compresses a mail including a header transferred from a mail transfer server, adds a new header to encapsulate the mail, and transmits the encapsulated mail to an IMAP server as a compressed mail. In response to a mail fetch request from a communication terminal, the relay server decapsulates and restores the compressed mail fetched from the IMAP server, and transmits the restored mail to the communication terminal. The relay server changes parameters such as the mail size, so that no inconsistency of IMAP commands occurs in compressing/restoring the mail.

During a period in which the CT imaging measurement is being performed, the image reconstruction portion reconstructs the three-dimensional CT image based on already-taken data on transmission images and displays the three-dimensional CT image before the CT imaging measurement is completed.

Abstract: Image retargeting is appropriately performed on stereo pair images composed of at least two images such as in three-dimensional displays. A path of connected pixels in first image data is calculated based on pixel gradient energy. Each pixel in second image data corresponding to each pixel in connected pixels in the first image data is calculated as an initial search point, based on the stereo correspondence relationship between the first image data and the second image data. Pixels that minimize energy between pixels of the first image data and pixels of the second image data in the proximity of the initial search point is calculated as a path of connected pixels in the second image data. A path of optimal connected pixels in the first image data is calculated using the energy.
