We compare two cosmological hydrodynamic simulation codes in the context of hierarchical galaxy formation: the smoothed particle hydrodynamics (SPH) code ‘GADGET’, and the Eulerian adaptive mesh refinement (AMR) code ‘ENZO’. Both codes represent dark matter with the N-body method, but use different gravity solvers, and fundamentally different approaches for baryonic hydrodynamics. In the Lagran...

This mixed-methods study aimed at investigating the effects of a gadget-based Internet multimedia extensive reading program on promoting language proficiency. In so doing, a pretest-posttest design was applied in the quantitative phase to comparatively analyze outcomes of three classes of college-level EFL learners (two experimental groups and one control, each including 30 university students)...

Trappers in New Zealand have traditionally used ground-set leg-hold traps to catch possums (Trichosurus vulpecula) but these sets also occasionally catch kiwi (Apteryx spp.) and weka (Gallirallus australis). To prevent the trapping of these birds, the Department of Conservation (DoC) requires all traps to be placed 70 cm above the ground in areas with kiwi and weka. To set leghold traps at this...

As the commerce environment becomes more competitive, companies are compelled to adopt a collaborative commerce (c-commerce) paradigm to sustain a competitive edge over the Internet. C-commerce demands a variety of collaborative interactions among multiple stakeholders. In order to develop c-commerce systems, this paper proposes a role-driven component-oriented methodology (RCOM), which consist...

The prevailing approach for building masked algorithms that can resist higher-order differential power analysis is to develop gadgets, that is, masked gates used as atomic blocks, that securely implement basic operations from the original algorithm, and then to compose these gadgets, introducing refresh operations at strategic places to guarantee that the complete circuit is protected. These co...
