Massive Open Online Courses (MOOCs) are growing substantially in numbers, and also in interest from the educational community. MOOCs are online courses aimed at large-scale interactive participation and open access via the Web that made them possible for anyone with an internet connection to enroll in free, university level courses. In this paper, we propose a novel method to discover various types...
A virtual structure, called the pseudo-rigid formation, for a multi-agent system has been proposed in [1] to deal with the formation problem. For 2-D problems, the underlying configuration space becomes the product of the two dimensional real vector space and the general linear group (R2 ?? GL(2)). It was shown that the objective function in the optimal design for collision avoidance can be represented...
Detailed step-by-step numerical procedures for computing the normalized detection threshold for the FFT J-out-of-L detector are presented. Accurate approximations are also provided for cases where numerical procedures break down due to rounding errors. Some of the numerical procedures detailed here are also useful in other signal processing problems.
This paper presents a novel method for learning classes of temporal sequences using a bag-of-features approach. We define a temporal sequence as a bag of temporal features and show how this representation can be used for the recognition and segmentation of temporal events. A codebook of temporal descriptors, representing the local temporal texture, is automatically constructed from a set of sample...
Purchasing behavior serves a base for online customer segmentation. Online purchasing behavior is characterized by purchasing sequences. This paper reviews the existing three major techniques of sequence data analysis, and discusses their limitations in online purchasing sequences analysis for customer segmentation. The study proposes a new data mining method for online customer segmentation, and...
A dynamic control model has been developed for robot motors controlling a high speed and high precision assembly process. This model includes the effects of parts tolerances and the tolerances of their associated assembly robots on assembly operations leading to the optimal allocation and distribution of tolerances to the workpieces and the robots. The application of modern control theory with constraints...
