Architectural (bad) smells are design decisions found in software architectures that degrade the ability of systems to evolve. This paper presents an approach to verify that a software architecture is smellfree using the Archery architectural description language. The language provides a core for modelling software architectures and an extension for specifying constraints. The approach consists...

Mechanical and mathematical model of external ballistics of the modern sport bow has been proposed. The force of air drag, shear friction, and drag on the fletching, and the additional force that depends on the angle of attack have been taken into account in the model. The corresponding Cauchy problem was stated and solved using the Runge-Kutta method and the program NDSolve from the software p...

There is evidence that the recall schema becomes more refined after constant practice. It is also believed that massive amounts of constant practice eventually leads to the emergence of especial skills, i.e., skills that have an advantage in performance over other actions from within the same class of actions. This advantage in performance was noticed when one-criterion practice, e.g., basketba...
