BACKGROUND Tinnitus or noise perception with no identifiable acoustic origin is a perplexing symptom to sufferers as well as to otolaryngologists saddled with managing such patients. With most studies from the continent focusing on etiologies and clinical types, there is paucity of information on psychoacoustic properties of tinnitus among Africans. SETTING Tertiary care otolaryngology clinic...

The paper to be presented at this conference (Dietrich and List 2013) sketches some basic ideas underlying a broader, ongoing decision-theoretic project. In that project, we aim to develop a new, general approach to decision theory which (i) improves upon standard decision theory in both its idealized, ‘rational’ and its more psychologically informed, ‘behavioural’variants (the former are assoc...

Recently, interest in generating dynamically consistent motion of human-like characters has been increasing in various areas. In particular, balance maintenance against perturbation caused by external force is an indispensable problem when we consider motion under a practical situation. Humans maintain their balance against sudden perturbation by large-scale whole-body motion, such as bending d...

DAR, dynamic alternative routing, is a simple but effective form of dynamic routing which is decentralised and which uses only a small amount of local information. This paper examines the modelling and behaviourial aspects of such a scheme. In particular various bounds are presented which hold for any kind of dynamic routing scheme, and can be used to assess the performance of DAR. DAR can be i...

Stress can be defined as a state of increased psychological, physiological and behaviourial preparedness. A stress reaction is a normal reaction that is considered necessary rather than harmful. Physical activity is generally deemed a stress factor that activates our physiological stress systems in the same way as exposure to psychological stress. The following chapter describes acute stress re...

In order to carry out experimental investigations on radial inflow gas turbine, a special test laboratory was designed and constructed at Sharif University of Technology. This laboratory is introduced in the present paper and experimental procedures are elaborated on. Then, some test results are presented and discussed. The trends of performance characterisitics match our expectation and show g...
