In vehicle–pedestrian crashes, head injuries account for an overwhelming percentage of all severe and fatal injuries. These injuries are caused by the linear acceleration and rotation of the head. To mitigate head injuries, tools such as Human Body Models (HBMs) are used in the development and evaluation of pedestrian safety systems. The tools need to be compared with experimental data to evalu...

My goal in my lectures was two-fold: to give first of all a sketch of Voevodsky’s foundational construction of the triangulated category of motives and its basic properties, and then to give an idea of some of the applications and wider vistas this construction has made possible...

Several features of subfitness are analyzed. Isbell’s Spatiality Theorem leads to the concept of T1-spatiality which is compared with the TD-spatiality. Subfitness is put into relation with other weak separation axioms (and with the existence of nearness), both in spaces and locales, and seeming discrepancies are explained. A new characteristic of subfitness by means of codensity is presented.
