Abstract: A system for performing a data analysis is provided. The system includes a curve fit module that determines a curve fit function for a data set. A parameter dependence determination module determines a dependence value for a parameter of the curve fit function. A parameter independence determination module determines an independence value for the parameter of the curve fit function based on the dependence value for the parameter. A graphical indicator generation module generates a graphical indicator for the parameter. The graphical indicator corresponds to the independence value for the parameter.

Abstract: A computer-implemented method and system for providing online language instruction to a student. A student client computer logs into a host system to commence an instruction session. The host assigns an instructor to the instruction session. A scene is simultaneously displayed on a student client computer and a client computer operated by the assigned instructor. A voice communication link is also provided. A predetermined lesson plan can be executed during the instruction session. The lesson plan can be selected according to a student profile stored on the host system. Study goals can also be listed on the computer operated by the instructor. Completion of a study goal can also be stored in the student profile. The student profile can be used to determine a next study goal for a particular student. The scene can be an interactive scene manipulated via the student client computer or via the client computer operated by the instructor.

Abstract: A Virtual Campus including interactive work plans and administrative resources presented online through a WEB interface. Through the Virtual Campus a learner can communicate with others, create and update an individual work plan, access required resources, store work, and be apprised of Virtual University announcements. While online, learners may create work groups with other learners, use a suite of business tools, interact with a registrar, or open a library data base. In addition, an online Virtual Campus can assess those skills a student has successfully mastered by analyzing progress through the aggregate of course modules completed. Academic and career guidance can be formulated referencing the accumulated detail of the students learning experience. Each software module and element can have a list of skills associated with it. The database of skills can reflect a students capabilities in greater detail than is possible using only a final course grade or grade point average.

Abstract: A collaborative learning system and method for implementing innovative criteria fashioned into an electronic learning experience that can be utilized at great distances. Learners can participate in the learning experience asynchronously thereby taking advantage of diverse schedules. A system is provided for offering network based education including software running on a computer or a plurality of computers for delivering educational services online. The network can include an internet protocol network wherein the servers can be accessed via a WEB interface. Software operative with a processor can cause an adaptive assessment tracking the learning style and progress of an individual learner. The system can also be responsive to an online assessment with remediation and guidance.

Abstract: A process is provided for recovering substantially pure triethylenediamine in liquid propylene glycol solutions directly from a crude triethylenediamine reaction mixture without the need to purify the triethylenediamine by crystallization. The process includes initially admixing propylene glycol with a crude triethylenediamine liquid reaction product mixture. The admixture thus formed is then distilled under conditions such that the triethylenediamine and propylene glycol codistill. The codistillate is then collected as the substantially pure triethylenediamine solute in liquid propylene glycol solution. The collected codistillate being substantially free of reaction by-products can be used directly to catalyze urethane systems.
