This invention relates to a method and apparatus in an interactive voice response system for caching VoiceXML documents. A method and system for processing a VoiceXML document prior to interpretation by a browser comprises: receiving a document from a web server; constructing a document object model (DOM) of the constituent parts of the document for interpretation by a browser; storing the DOM and the constituents parts in cache memory whereby next time the DOM and parts are required for interpretation it is retrieved from cache memory rather than constructed again from the source code. The constituent parts may be re-used in the or other documents. The constituent parts are separated into logic and data parts.

A system to facilitate electronic commerce associated with an online marketplace, program product, and methods are provided. Electronic commerce over a computer network is facilitated by a computer system that forms a community of computers that enable the users to buy and sell items in an online marketplace. To list the item on an online marketplace website, for example, the selling user posts an item with the marketplace website by completing an online-item creation form. The form requires input related to the item, such as a description, sale price or minimum bid, shipping instructions, and the like. The selling user uploads an image file of the item to the marketplace website's server. The server contains a random image size generator that generates at least two additional images of the item that are presented to the selling user for selection of the image that the selling user wants to include on the selling website to advertise the item.

A preferred embodiment of the device is in clinical trials of microbicides inhibiting transmission of the HIV virus.

A system that captures both whiteboard content and audio signals of a meeting using a video camera and records or transmits them in real-time. The Real-Time Whiteboard Capture captures pen strokes on whiteboards in real time using an off-the-shelf video camera. Unlike many existing tools, the RTWCS does not instrument the pens or the whiteboard. It analyzes the sequence of captured video images in real time, classifies the pixels into whiteboard background, pen strokes and foreground objects (e.g., people in front of the whiteboard), and extracts newly written pen strokes. This allows the RTWCS to transmit whiteboard contents using very low bandwidth to remote meeting participants. Combined with other teleconferencing tools such as voice conference and application sharing, the RTWCS becomes a powerful tool to share ideas during online meetings.

The present invention envisages a GSM mobile telephone in which a line of icons is displayed on a display. As a user navigates through the displayed line of icons, the positions of the icons alter so that the selectable icon moves to the head of the line.

An approach is provided that sends a JIT compilation request from a first process that is running on one processor to a JIT compiler that is running on another processor. The processors are based on different instruction set architectures (ISAs), and share a common memory to transfer data. Non-compiled statements are stored in the shared memory. The JIT compiler reads the non-compiled statements and compiles the statements into executable statements and stores them in the shared memory. The JIT compiler compiles the non-compiled statements destined for the first processor into executable instructions suitable for the first processor and statements destined for another type of processor (based on a different ISA) into instructions suitable for the other processor.

A hyperspectral image sparse unmixing method based on random projection includes the following four main steps: (1) data are read by a computer under the environment of MATLAB R2008b; (2) the hyperspectral image data and the hyperspectral library data are randomly projected by the computer; (3) a target function for sparse unmixing is constructed, and the split Bregman algorithm is used for optimizing the target function and working out an extremum until reaching convergence and stopping conditions; (4) an appropriate threshold value is set to process a abundance fraction matrix, so that a final abundance fraction graph and end members can be obtained. The hyperspectral image sparse unmixing method based on random projection utilizes a hyperspectral database to choose the end members, and overcomes the defect that the end members worked out by the conventional algorithm cannot strictly correspond to the spectra of pure materials in the standard hyperspectral database; and moreover, the hyperspectral image sparse unmixing method based on random projection uses the random projection technology to carry out dimensionality reduction on raw data, thus achieving the effects of saving memories and reducing the calculation load. The hyperspectral image sparse unmixing method based on random projection realizes rapid quantitative analysis on hyperspectral images, and has practical value and a broad application prospect in the field of hyperspectral remote sensing image analysis.
