Steady-state error of a system with fuzzy controller.

We consider the problem of control error of a fuzzy system with feedback. The system consists of a plant, linear or nonlinear, fuzzy controller, and feedback loop. As controller we use both PD and PI fuzzy type controllers.

Expandable Non-invasive Prostheses - an Alternative to Pediatric Patients with Bone Sarcoma.

The arthroplasty concerns replacement of a joint that does not function due to bone sarcoma that a child suffers from. Osteosarcoma and Ewing's sarcoma are the most common types of pediatric bone cancer and they afflict mainly long bones, i.

Complex-valued multistate neural associative memory.

A model of a multivalued associative memory is presented. This memory has the form of a fully connected attractor neural network composed of multistate complex-valued neurons. Such a network is able to perform the task of storing and recalling gray-scale images.
