摘要： In computer multimedia technology, a system, method and computer program product for optimizing images and transmission of images of a web-page transmitted over the Internet and furthermore, optimizing images of a web page on a network server. The method includes detecting the images in the web page to determine the relationship among the images; in response to the determination of the relationship among the images, combining two or more related images into a combinational image; and updating the web page to replace references to the related images with a reference to the combinational image. By optimizing web page images, the server's work required for handling heavy amount of HTTP requests in transmitting the web page images is decreased and the bandwidth requirement for transmitting the web page images is reduced. The quality of the original image is not lowered. And there is no need to make any change to the operation at the client side.

摘要： Systems and methods for determining a trend in vertical track modulus are disclosed in accordance with embodiments of the present invention. Vertical deflection data is collected along a particular section of railroad track. A first set of vertical track modulus is determined, based in part, on the collected vertical deflection data. At a second time, vertical deflection data is again collected along the particular section of railroad track to be used in determining a second set of vertical track modulus. At least the first and second sets of vertical track modulus are analyzed to determine a mathematical algorithm that facilitates developing a trend in the vertical track modulus of the railroad track.

摘要： An interface includes a port and a port control module. The port control module detects whether a remote device communicating with the port is one of a Universal Serial Bus (USB) device and a satellite digital transceiver (DT) device. The port control module selectively generates one of a USB configure signal and a satellite DT configure signal. A USB control module selectively configures the interface to communicate with the USB device when the USB configure signal is received. A satellite control module selectively configures the interface to communicate with the satellite DT device when the satellite DT configure signal is received.
