A course material that is applied to a substrate during fabrication of a composite item is inspected by a system that includes a vision assembly. The vision assembly includes an area light, a line generator, a sensor, and an image processor. The area light illuminates an area of the course material. The line generator generates a line of illumination across the area. The sensor captures an image of the area. The image processor analyzes the image. The image processor is configured to identify debris on the course material in response to the area light being activated and the image processor is configured to identify placement aberrations in response to the line generator being activated.

A system for increasing user interaction with a digital video library. In response to receiving a question by an interactive digital video library server from a user regarding course material being presented from a digital video library, it is determined whether the question is in an audio format. In response to determining that the question is in an audio format, the question is converted into a text format. The course material is searched in a time sliced video index database for an answer to the question using keywords found in the text format of the question. Also, other course materials similar to the course material are searched in a video knowledge base. A weight is assigned to each search result hit found in the course material and the other course materials. Search result hits are outputted in a priority order according to assigned weight and user preference.

The present invention is a system and method for maintaining the integrity of data during the offline mode of an e-learning process. The invention maintains the integrity of online course material in a learning management system by determining when a student attempts to access online course material and to downloaded the material from a learning management server to a student server for offline utilization resulting in an offline access mode. The invention then provides a set of procedures for monitoring the course material when it has been accessed. The set of procedures may determine that the course material is in an offline access mode and prevent the student from accessing the course object from the learning management server while the course object is in the offline access mode. Further, the system and method of the present invention may also serve to synchronize the course material between the learning management server and the student server by copying the course material from one server to another. In one embodiment, the system and method of the present invention can prevent a student from uploading the course material to the learning management server unless the student has completed the one or more progress objectives associated with the course object. Finally, the set of procedures can provide a security mechanism to insure the security of the online course material when it is in the offline access mode.

The invention discloses a method and a platform for grade analysis, diagnosis prediction and learning resource pushing. The method and the platform comprise the following steps: an education server receives the answering subject information and the answering answer information sent by a student terminal; according to the answering subject information, the pre-stored reference answer information base is called to calculate the error information; Matching the pre-stored subject knowledge point database according to the answering subject information, analyzing the incorrect question information in the subject knowledge point database, and finding the knowledge point set corresponding to the incorrect question information; According to the set of knowledge points, obtaining the mastery degreeof the knowledge points in the subject by the student through machine learning, and setting pushing priority coefficient of the knowledge point, and pushing the course material of the pre-stored learning resource database to the student terminal according to the pushing priority coefficient, so that the effective information in the score can be fully obtained, the correctness of diagnosing and predicting the learning quality can be improved, and matching learning resources can be pushed pertinently.

The invention discloses a road subbottom material and a relative preparation method, wherein the road subbottom material uses 10-80% of waste concretes, 10-70% of crushed bricks, 5-40% of waste residue and 2-20% of adhesive as main components, while the total amount is 100%. The inventive road subbottom has high compressive strength, better hydraulicity, high resilient modulus, strong distorsion resistance ablity and wide application for the road construction of soft soil foundation at riverside and coastal area. The invention can resolve the treatment problems of waste concrete, waste brick and waste residue, to reduce the consumption and development of natural sand gravel and release the scarcity of natural sand gravel, to satisfy sustainable development. The invention has the advantages of energy saving, reduced consumption, material saving and emission reduction.

The techniques disclosed teach automatically generating educational course material according to presentation rules. A course model creation engine retrieves course objectives, course outlines, and the mapping of those to each other to create a course model. A course component creation engine retrieves course content and presentation rules to create the course components. A publication engine published the course material in compliance with the presentation rules.

Techniques pertaining to automating generation of curricula for a class of students with blended-learning contents are presented. The blended-leaning contents provide common topics shared by all the students in a class as well as self-learning materials for sub-groups of the class. This approach creates curricula optimally attending to students with different interests and backgrounds. The course materials are selected by searching multiple external sources publically available while filtering the search results through inputs of the students and requirements set by the instructors. The course contents and schedules of the curricula are further optimized by organizing the filtered search results with respect to a set of constraints.
