Engineering with Computers

Abstract In this paper we explain the fractal geometry of refined and derefined triangular and tetrahedral meshes by means of the application of iterated function systems (IFS). These meshes feature a remarkable amplifying invariance under changes of scale. The applications of IFS families are shown equivalent to the use of adaptive strategies that combine the refinement procedure with the dere...

Botnets — Secret Puppetry with Computers

Botnets have traditionally been and are still considered one of the top threats to Internet security. The scope of botnets transcends the boundaries of Internet security, leveraging a variety of technologies and strategies. They are capable of launching attacks at a massive scale that are difficult to defend. In this paper we describe anatomy of botnets and malware that recruits new bots, varia...

Augmenting Cognition with Wearable Computers

Mobile devices are becoming more commonplace and part of our daily lives. We have found that wearable computers offer a unique perspective on the interaction issues present with mobile computing. In this work we explore augmenting cognition through the use of wearable computing. In particular we investigate how wearables are currently used and explore two input techniques that can be used to pr...

Systems Simulation with Digital Computers

A machine-independent examination of the associated programming problem i s conducted and illustrated by means of a n example. Finally, the nature and application of simulation languages are noted. By system, we have in mind the meaning accorded by Webster, " a set of objects united by some form of regular interaction or interdependence. " Change in a system is regarded as change in the propert...
