Epidemiological simulation environments produce extremely large quantities of scientific, numeric digital objects. Traditional digital libraries and services fail to effectively support simulation-based tasks. The requirements for this class of digital libraries can be described through formal definitions of content, users, and services. The set of definitions provide a basis for developing a s...

Computer Aided Design (CAD) tools are commonly adopted in the design, synthesis and simulation of digital circuits. Switch-level simulation, logic synthesis, timing analysis and architecture optimizations are essential CAD tools during digital IC design flow. However, the HDL coding, computation complexity and simulation time overhead makes the design turnaround time much longer. This drawback ...

the full adders (fas) constitute the essential elements of digital systems, in a sense that they affect the circuit parameters of such systems. with respect to the mosfet restrictions, its replacement by new devices and technologies is inevitable. qca is one of the accomplishments in nanotechnology nominated as the candidate for mosfet replacement. in this article 4 new layouts are presented fo...

This study examines the application of digital ecosystems concepts to a biological ecosystem simulation problem. The problem involves the use of a digital ecosystem agent to optimize the accuracy of a second digital ecosystem agent, the biological ecosystem simulation. The study also incorporates social ecosystems, with a technological solution design subsystem communicating with a science subs...

The current importance of computer simulation of dynamic systems is well-known. Such simulation is useful in system analysis, design, and testing, as well as in the training of human operators. Whenever a computer simulation involves interaction with actual system hardware (including humans) the computation must by definition take place in real-time; i.e., the computer must solve the simulation...
