An apparatus or web server for assisting a user in selecting a route based on tracked popularity of routes traveled by other users and a desired user activity. The method comprises: setting the state of a buffer to be ACTIVE when a file section stored in the buffer is requested by any users; setting the state of the buffer to be INACTIVE when users no longer request the file section stored in the buffer, the buffer in INACTIVE state having a lifetime; changing the state of the buffer from INACTIVE to FREE when the lifetime decreases to zero. In the process of dispersion, the lyophilized liquid composition and the powder of the present invention can spontaneously generate particles of 200-500 nm by gently shaking with hands without a powerful mechanical force. The method includes forming a first set of network element pairs, ordering a first number of network element pairs, forming a second set of network element pairs, measuring a measured network performance metric between a first network element pair and computing a computed network performance metric. W1 correlation results storage elements are utilized to store correlation result values. A request for supplementary information may be generated by using a mouse to first position a cursor over an active display element.
