Read More NCSA has developed a software suite that allows novices to edit and manage content directly on a website and corporations to maximize the efficiency of both the users in their organization and of their content management system. This comprehensive software solution is ideal for individuals, small businesses and large corporations alike, since it provides any worker with the power to easily create, update, organize, and modify content.Thus families and small businesses, including home-based businesses, gain the ability to set up and maintain a web presence, and large corporations free up the time of their IT personnel to focus on other more difficult and time consuming technology issues. Editable Web Browser (EWB) EWB allows highly simplified, real-time creation and editing of Web pages by authorized users. Rather than relying on a webmaster to make changes or post content, authorized users can now create and maintain a website or particular web pages themselves.Tasks such as adding new pages, correcting typos, and updating time sensitive information can be performed in the Web-browser environment with which they are already familiar. Documents are edited on the user's machine and transferred to the Web server, but to the user, EWB appears to make changes instantly on the Web server. EWB also can be used to create Web pages from scratch, providing a friendly interface for users who are not tech savvy. Online Document Sharing/Collaboration Ideal for small companies, clubs, and other organizations, allowing them to publish to the World Wide Web via a single mouse click. Users can intuitively create remote shared files with an integrated multilevel security system to enable online collaboration. If desired, these shared files can be made easily accessable via a Web browser or by using a Windows or Unix client. Online Database Creation and Management Users with little or no database knowledge can create Web-accessible databases and easily populate and search them. Users can select the field types-text, numbers, dates, images, etc.- naming them and easily uploading the relevant content. Most currently available Web-based database creation tools require the user to design and manage both the database and a set of HTML pages for accessing that database. This software provides a database with built-in Web support, allowing one-click creation of search and browse pages. Conversely, the user can choose to create their own HTML code by hand or by using the Editable Web Browser as an advanced option for presenting the database. Digital Multimedia Management Create "albums" containing digital multimedia files (digital multimedia files containing photos, video, audio, etc.) and publish electronic galleries and scrapbooks on the Web quickly and easily. This software provides Web based scrapbooks, allowing users to interactively place content such as images and text with absolute positioning. These capabilities are further expanded by allowing users to make audio and freehand drawing annotations. Content Management System (CMS) with Variable Predicate Targeting Unlike static Web pages with permanent content, a CMS creates template-based Web pages, temporarily importing content (e.g., articles, product information) from a database into the template fields. This CMS is a unique design that provides a flexible environment for the rapid creation and deployment of database-driven Web sites. Novel user-developed applications can be easily incorporated into a working site that already contains the necessary supporting systems by use of simple plug-ins. A key element of this CMS is its "variable predicate content targeting system." Targeting involves changing how information is delivered according to time, the device being used to access the Web page(e.g., cell phone, personal digital assistant[PDA]), specifics about the person viewing the page, or other arbitrary criteria. This targeting system uses several novel techniques to provide an extremely flexible system that is considerably more powerful than existing systems, but in a much simpler and more user friendly form.

The reliability of those evaluations is key for the successful application of iGAs. However, even moderately-sized problems my require thousands of evaluations that are sometimes between rather similar solutions which can lead to frustration and inconsistent evaluations. This invention provides a scheme for actively combating user fatigue and inconsistency in iGAs. The efficiency gained from using an interactive procedure by requiring fewer evaluations is lost if the user is unable to provide consistent evaluations. This invention leads to the creation of active iGAs (aiGAs) which include steps of learning from human-computer interaction that actively guide the search-based interaction process. The innovation includes an evaluation-relaxation scheme that actively combats user fatigue and inconsistency by addressing two important issues: Lack of computable fitness Lack of a systematic method for modeling user-decision process Active iGAs optimize a synthetic fitness to obtain educated guesses of the user preferences and thereby reduce the number of user evaluations required. Three important components enable this invention to combat user fatigue and inconsistency. Partial Ordering: Qualitative decisions made by the user about relative solution quality are used to generate partial ordering of solutions Induced Complete Order: Concepts of non-domination and domination count from multi-objective evolutionary algorithms to induce a complete order of the solutions in the population based on their partial ordering Surrogate Function: Induced order is used to assign ranks to the solutions and use them Applications This technology provides the ability to solve difficult problems such as data management, engineering design and optimization, and time and resource allocation in large-scale businesses and organizations, more quickly, reliably, and accurately.

Read More Polymer materials are ubiquitous in everyday life and are used in various applications (medical, automobile, electronics, structural, etc.). These materials experience stress through normal use, which can lead to damage and failure of the product. Having the ability to detect damage and locate areas under high stress in situ is essential to eliminating failure of the material. Our invention incorporates a chemical into the polymer backbone that signals an area under stress by causing a visible color change in the material. This invention will allow for damage detection via a color change of the material and thus early repair before failure, ultimately extending the lifetime of the product. For this invention, the chemical incorporated into the polymer backbone is a stress-responsive spiropyran mechanophore. One spiropyran molecule is placed in the center of the polymer backbone and undergoes a structural change in response to stress. This change causes a visible color change of the polymer material. There are several advantages to this method of stress/damage detection. The damage sensing mechanophore is chemically incorporated into the polymer backbone and hence is distributed evenly throughout the material. Since the spiropyran is chemically incorporated, no extra processing steps are required post-polymerization and the mechanophore cannot be eliminated by everyday wear. Finally, damage can be detected visually without removing parts or using expensive detection equipment such as UV of x-ray monitors.

Read More A self-indicating material system may include a solid polymer matrix having a first color, a first plurality of capsules in the matrix, and a plurality of particles in the matrix. The first plurality of capsules includes a first reactant, and the plurality of particles includes a second reactant, which forms a product when in contact with the first reactant. When a crack forms in the polymer matrix, at least a portion of the first plurality of capsules is ruptured, the first and second reactants form the product in the matrix, and the portion of the polymer matrix containing the product has a second color different from the first color. A self-indicating material system may include a solid polymer matrix, a plurality of capsules in the matrix, and an activator in the matrix, where the polymer matrix includes a first polymer and has a first color, the plurality of capsules includes a polymerizer, and the activator is an activator for the polymerizer. When a crack forms in the polymer matrix, at least a portion of the plurality of capsules is ruptured, the polymerizer and the activator form a second polymer in the crack, and the second polymer has a second color different from the first color.

Read More A spray nozzle assembly includes a pressure dependent variable spray orifice and an internal chamber which is at least partially bound by a flexibly deformable sidewall. At its distal end, the sidewall terminates at a distal face defining the spray orifice extending therethrough. A metering member extends distally from the internal chamber and through at least a portion of the spray orifice. As the pressure of a liquid supplied to the internal chamber by a liquid supply pathway varies, the flexibly deformable sidewall expands or contracts in response thereto. As the sidewall expands and contracts, the distal face moves relative to the metering member to change the effective size of the spray orifice.
