“…This challenge is made greater by a lack of pedagogical tools that uniformly address structural design at every level. Many excellent GUI-based logic simulation systems have been developed and are available for download (Masson [8] is an early example; see [2,15], for comprehensive, though dated, summaries; recent additions include JLS [10], Digital Works 3.0 [1] and Logisim 2.1.6 [3].) These systems are very useful for studying basic combinatorial and sequential circuits.…”

Students of Computer Organization should be able to "learn by doing" at all levels of computer design. Digital logic circuitry is frequently taught using simulation software, however such platforms are often limited to exposing only a narrow range of design levels. This paper describes how, in the new multilevel simulation system DLSim 3, we are able to incorporate abstraction and extensibility to present the many levels of complex circuit designs in a single environment: from low level combinational and sequential circuits, through models of complete CPUs. Among other features, DLSim 3 is able to accomplish this by providing three different types of circuit abstraction: cards, chips, and plug-ins. Using DLSim 3, students recognize the uniformity of system structure, as well as the principles of abstraction that link the various levels of design.

The dynamics of the impact process of a non-Newtonian gelled fuel simulant droplet was studied experimentally. A comparison between the impact process of the gel simulant and that of a neat Newtonian fluid reveals a similar behaviour during the kinematic phase of the droplet impact. However, significant differences, both quantitatively and qualitatively, between the investigated fluids were found during the later spreading, relaxation and equilibrium phases of the impact process. Numerical simulations for the neat Newtonian fluid were found to accurately predict the centreline height during the kinematic phase for both of the fluids. A novel dynamic model for drop shape based on elastic spring and dashpot elements using the Bessel function to describe the periodic term is presented. Very good agreement of the dynamic model with the experimental data was obtained.
