Learning outcome assessment is of great significance in the field of traditional on-campus teaching especially on the courses of programming languages. In this work, we take advantage of the data offered by our programming assignment judge system and propose a new IRT-BKT model for estimation of learning outcome. This new framework: Item Response Theory (IRT) model that estimates students' initial...
Distribution System State Estimation (DSSE) is nowadays essential to enable the smart management of medium and low voltage grids. Due to the lack of a suitable measurement infrastructure, DSSE usually relies on the use of power injection pseudo-measurements derived from the knowledge of the historical and statistical behaviour of loads and generators. The uncertainty of these pseudo-measurements could...
This paper is concerned with the estimation of the height and width of freespace based on a Bayesian Recursive (BR) algorithm for an autonomous wheelchair using a stereoscopic camera system for disabled people. A 2D distance map for the purpose of freespace estimation is converted from a 3D point map using geometric projection and computation. The comparison of this 2D map to a 2D map obtained from...
