The function of a router is to switch arriving packets to their correct output destination. A router is built to achieve a specified capacity (the sum of the rates of its interfaces), and users expect a router to consistently achieve this capacity. However, no commercial high-speed router can guarantee today that it will achieve its full capacity for all arrival traffic patterns. This is due to...

The Global Asthma Network (GAN), established in 2012, followed the International Study of Asthma and Allergies in Childhood (ISAAC). ISAAC Phase One involved over 700 000 adolescents and children from 156 centres in 56 countries; it found marked worldwide variation in symptom prevalence of asthma, rhinitis and eczema that was not explained by the current understanding of these diseases; ISAAC P...

Stream ciphers are often used in applications where high speed and low delay are a requirement. The ISAAC keystream generator is a fast software-oriented encryption algorithm. In this papers the security of the ISAAC keystream generator is investigated. Cryptanalytic algorithm is developed for a known plaintext attack where only a small segment of plaintext is assumed to be known.

This paper presents some properties of he deterministic random bit generator ISAAC (FSE’96), contradicting several statements of its introducing article. In particular, it characterizes huge subsets of internal states which induce a strongly non-uniform distribution in the 8 192 first bits produced. A previous attack on ISAAC presented at Asiacrypt’06 by Paul and Preneel is demonstrated to be n...

Cognitive rehabilitation has the capacity to empower persons with brain-injuries and help them achieve heightened functional, personal, and social interactions within their environments. Interventions aimed at compensation for deficits and adaptation to cognitive disability can be aided through the use of assistive technology devices (ATD's). ATDs allow for their users to experience greater lev...

Like so much research, the findings from the ISAAC program have raised more questions than they have answered. Despite their limitations, the ISAAC findings provide the basis for further studies to investigate factors that potentially contribute to these international patterns and may lead to novel public health and pharmacologic intervention strategies that reduce the prevalence and severity o...
