We introduce in this paper the RELIEF retrieval system, a system for image retrieval based on the conceptual graph formalism. Conceptual graphs can be used as a simple and expressive language for indexing and retrieving non– textual documents. In this formalism the implementation of the matching function between a query and a document is obtained by using the so-called projection operator betwe...

Bas-reliefs are widely used in the world around us, for example, on coinage, for branding products, and for sculptural decoration. Reverse engineering of reliefs—extracting existing reliefs from input surfaces—makes it possible to apply them to new items; relief editing tools allow modification of reverseengineered reliefs. This paper presents a novel approach to relief extraction based on diff...

Chronic pain affects more than 50 million Americans and results in more than 25 million physician visits a year for lower back pain alone.1 The burden is particularly great in the elderly, in whom associated cardiovascular disease is the leading cause of death. Nonselective, nonaspirin, nonsteroidal antiinflammatory agents (NSAIDs) are effective analgesic, antiinflammatory, and antipyretic agen...

Relief valves are widely used in industrial machinery. Due to the outlet of the relief valve being connected to the tank, the pressure drop of the relief valve is frequently equal to the inlet pressure. Accordingly, the energy loss of the relief valve is very high in some cases and this will worsen with an increase in the rated pressure of the hydraulic system. In order to overcome the disadvan...
