Robots play such remarkable roles in humans’ modern lives that performing many tasks without them isimpossible. Using robotic systems is gradually increasing the tasks allocated to them and they are becomingmore complex and critical. Software reliability is one of the most significant requirements of robots. Forenhancing reliability, systems should be inherently designed to be tolerable of soft...

It is a fact that software has bugs. These bugs can lead to failures. Especially dependability and security failures are a great threat to software users. This thesis introduces four novel approaches that can be used to automatically harden software at the user’s site. Automatic hardening removes bugs from already deployed software. All four approaches are automated, i.e., they require little s...

This paper gives an overview of Pierre Bayle’s theory of toleration and derives a normative principle of toleration from it that is meant to compete with other normative principles of toleration such as the Harm principle. INDEX WORDS: Political philosophy, Social philosophy, toleration, religion, Christianity, justice, legitimacy, stability, John Locke, Pierre Bayle, Baruch Spinoza, Harm princ...

This paper introduces a hardware method of improving the performance of any synchronous digital system. We exploit the well-known observation that typical delays in synchronous systems are much less then the worst-case delays usually designed to, typically by factors of two or three or more. Our proposed family of hardware solutions employs timing error toleration (TIMERRTOL) to take advantage ...

This paper rereads David Hume’s Dialogues Concerning Natural Religion as dramatising a distinctive, naturalistic account of toleration. I have two purposes in mind: first, to complete and ground Hume’s fragmentary explicit discussion of toleration; second, to unearth a potentially attractive alternative to more recent, Rawlsian approaches to toleration. To make my case, I connect Dialogues and ...

Purpose This paper aims at understanding the dynamics underlying toleration as a complex social phenomenon and its pattern on Facebook during June 30th revolution in Egypt. Thanks to huge advances ICT, internet-mediated research (IMR) has become one of most prominent methodologies sciences. Discussions network sites cannot be neglected studying emerging phenomena such changes public opinion, cu...

The data transmission potential inherent in optical networks is enormous, and because of this great potential, optical networks are in dire need of fault toleration. Recently, various fault toleration techniques exploiting the special properties of optical data transmission have been presented, one of the most interesting being backup-multiplexing. Backup multiplexing comes in a couple of diffe...
