Noninvasive extendable prosthesis: a new design

A New Controlling Parameter in Design of Above Knee Prosthesis

In this paper after reviewing some previous studies, in order to optimize the above knee prosthesis, beside the inertial properties a new controlling parameter is informed. This controlling parameter makes the prosthesis able to act as a multi behavior system when the amputee is opposing to different environments. This active prosthesis with the new controlling parameter can simplify the contro...

A New Metacarpophalangeal Joint Prosthesis

The metacarpophalangeal (MCP) joint is crucial for hand function, but the joints are frequently affected by arthritis, leading to pain and disability. Joint replacement implants are used to replace the diseased MCP joint, but current and past designs have had varying success. This paper presents a new MCP joint prosthesis based around an idea of combining a single piece elastomer implant with a...

A New Construction of Non-Extendable Intersecting Families of Sets

In 1975, Lovász conjectured that any maximal intersecting family of k-sets has at most b(e− 1)k!c blocks, where e is the base of the natural logarithm. This conjecture was disproved in 1996 by Frankl and his co-authors. In this short note, we reprove the result of Frankl et al. using a vastly simplified construction of maximal intersecting families with many blocks. This construction yields a m...

A Logic-based Approach to Prosthesis Design

The application of techniques from logic databases and definite clause grammars is illustrated in RaPiD, an intelligent design system used in prosthetic dentistry.
