My dissertation work has been twofold. The first part focuses on enhancing cellphone awareness with the purpose of minimizing inappropriate cellphone interruptions and to create more socially intelligent and thus accepted cell phones. I have introduced, designed, and investigated three different approaches toward that goal. The approaches capitalize on the emerging fields of ubiquitous computin...

Crigler-Najjar syndrome

Crigler-Najjar syndrome type 2.

Crigler-Najjar syndrome is a rare disorder of bilirubin metabolism with two distinct forms: type 1 and type 2. We report three patients with Crigler-Najjar syndrome type 2 (CN-2). All patients had serum bilirubin values higher than 171 micromol/L and deep yellow skin color. The results of other liver function tests, glucose-6-phosphate dehydrogenase activity and hematology tests were normal, an...

RAZAN: a high-performance switch architecture for ATM networks

In this paper a high-performance packet switch architecture based on the improved logical neighbourhood (ILN) interconnection network, called RAZAN, is presented. RAZAN is an NxN multistage interconnection network (MIN) which consists of n stages, where n = log(2)N, of switching elements. Each stage consists of a column of N switching elements and (n + 1) x N links. Each switch has n + 1 inputs...

Inheritance of type 2 Crigler-Najjar hyperbilirubinaemia.

The families of three patients with Crigler-Najjar hyperbilirubinaemia, type 2, whose plasma bilirubin levels had responded to phenobarbitone treatment, were investigated. All the parents and several relatives had mildly raised bilirubin levels. It is suggested that this condition may be an example of genetic heterogeneity and that the propositi had inherited two different abnormal genes. The s...
