Consider an information network with harmful procedures called attackers (e.g., viruses); each attacker uses a probability distribution to choose a node of the network to damage. Opponent to the attackers is the system protector scanning and cleaning from attackers some part of the network (e.g., an edge or a path), which it chooses independently using another probability distribution. Each att...

Effective drug delivery to the lungs by a DPI device requires the air-stream through the device to have sufficient power to aerosolise the powder. Furthermore, sufficient turbulence must be induced, along with particle-wall and particle-particle collisions, in order to de-aggregate small drug particles from large carrier particles. As a result, the emitted and the fine particle doses produced b...

There are many designs of hip protectors ranging from small elliptical shaped hard shell designs to large circular soft pads. They are held in position usually by being contained in a close fitting pocket on a garment that patients wear all the time they are at risk of sustaining a fracture of the hip if they fall onto the area of the greater trochanter (GT). It is important for the function of...

Introduction: Although strides have been made to improve breast augmentation surgery, they have focused on the use of single implant devices, necessitating adjustments to the type of operation performed and implants used. And although some breast types obtain excellent results, many others are less than optimal. By developing a thin synthetic expanded polytetrafluoroethylene device, the Pocket ...

This paper describes ongoing research to harden the lower part of the software stack, normally not covered by existing software-based fault-tolerance mechanisms. I discuss a combination of four techniques to harden the operating system kernel against hardware faults: resilient data structures, asynchronous checks, restartable OS services, and message protection. I present initial performance re...
