In the current paper, a method for deriving the analytical expressions for the velocity and vortex stretching terms as a function of the spherical multipole expansion approximation of the vector potential is presented. These terms are essential in the context of 3D Lagrangian vortex particle methods combined with fast summation techniques. The convergence and computational efficiency of this approach is assessed in the framework of an O(N ...

In this work, we focus on automatically recognizing social conversational strate- gies that in human conversation con- tribute to building, maintaining or some- times destroying a budding relationship. These conversational strategies include self-disclosure, reference to shared ex- perience, praise and violation of social norms. By including rich contextual fea- tures drawn from verbal, visual and vocal modalities of the speaker and ...

An adaptive scheme for perimeter control of heterogeneous transportation networks is presented. The proposed methodology utilizes the concept of the Macroscopic Fundamental Diagram (MFD) integrated with an adaptive optimization technique. First, a new MFD-based macroscopic model is introduced to describe the dynamics of heterogeneous urban networks that can be partitioned in a small number of homogeneous regions. The non-linear model ...

Statistical models of student responses on assessment questions, such as those in homeworks and exams, enable educators and computer-based personalized learning systems to gain insights into students' knowledge using machine learning. Popular student-response models, including the Rasch model and item response theory models, represent the probability of a student answering a question correctly using an affine function of latent factors. ...
