Embedded systems are suggestive targets for code injection attacks in the recent years. Software protection mechanisms, and in general computers, are not usually applicable in embedded systems since they have limited resources like memory and process power. In this paper we investigate side channel characteristics of embedded systems and their applicability in code injection attack detection. T...

The skyshine radiation phenomenon consists of the scattering of primary photon beams in the atmosphere above the roof of a medical linear accelerator facility, generating an additional dose at ground level in the vicinity of the treatment room. Thus, with respect to radioprotection, this situation plays an important role when the roof is designed with little shielding and there are buildings ne...

Dr. Zitha Mokomane is a Senior Research Specialist in the Population Health, Health Systems and Innovation research programme at the Human Sciences Research Council in South Africa. She holds a MA and a PhD (Family Demography), both from the Australian National University. Before joining the Human Science Research Council, Dr Mokomane was a Senior Lecturer in the Department of Population Studie...

Transient voltage surge suppressors (TVSSs) using MOV technology are widely used to protect power systems and components against the effects of transient overvoltages. However MOVs can fail explosively under certain conditions, and protection is needed. Thermal protectors provide protection against failure under sustained power-frequency overvoltages, and in the paper the requirements for and p...

For the last decades, the design floods of numerous embankment reservoirs were re-evaluated, and the revised spillway outflows are typically larger than those used in the original designs. As a result, a number of overtopping protection systems were developed for embankments and earthfill dams, with applications encompassing river dykes, coastal barriers for storm surge and tsunami protections....

Theories of protection powerful enough to resolve security questions of computer systems are considered. Mo single theory of protection is adequate for proving whether the security afforded by an arbitrary protection system suffices to safeguard data from unauthorized access. When theories of protection are restricted' to computer systems which are bounded in size, adequate theories exist, but ...
