Define a mixture with volume V containing a certain amount of clay (Vc) and sand (Vs), i.e. V = Vc + Vs. The intrinsic porosity of the clay is φc, defined as the ratio of pore volume in the clay V c p to the volume of clay, i.e. φc = V c p /Vc, and the intrinsic porosity of sand is φs = V s p /Vs. The surface areas of the pores in the clay and in the sand are noted S p and S s p respectively. S...

Decades of scientific research shows that intrinsic motivation (IM) is a powerful "engine" of learning and positive development. This chapter synthesizes the research, first showing how the psychological state of IM is associated not only with enhanced engagement and perseverance in an activity, but also with greater use of meta-cognitive strategies and deeper processing of information. These f...

This paper presents an extensive evaluation of five different alignments and investigates their impact on the corresponding MT system output. We introduce new measures for intrinsic evaluations and examine the distribution of phrases and untranslated words during decoding to identify which characteristics of different alignments affect translation. We show that precision-oriented alignments yie...
