This paper develops a uniform definition of control system design problems using a vector space. Design difficulties by conventional analytical and numerical means are discussed. Associated problem-classification is presented, together with a possible automation technique that transforms unsolvable design problems to solvable analysis and non-NP design problems. Practically realisable design au...

NURBS surfaces can be non-uniform and defined for any degree, but existing subdivision surfaces are either uniform or of fixed degree. The resulting incompatibility forms a barrier to the adoption of subdivision for CAD applications. Motivated by the search for NURBS-compatible subdivision schemes, we present a non-uniform subdivision algorithm for B-splines in the spirit of the uniform Lane-Ri...

In this work a glass micromodel which its grains and pores are non-uniform in size, shape and distribution is considered as porous medium. A two-dimensional random network model of micromodel with non-uniform pores has been constructed. The non-uniformity of porous model is achieved by assigning parametric distribution functions to pores throat and pores length, which was measured using ima...

DESIGN OF NON-UNIFORM LINEAR ARRAY VIA LINEAR PROGRAMMING AND PARTICLE SWARM OPTIMIZATION AND STUDIES ON PHASED ARRAY CALIBRATION

Hashing algorithms have been widely adopted for fast address look-up, which involves a search through a database to find a record associated with a given key. Hashing algorithms transforms a key into a hash value hoping that the hashing renders the database a uniform distribution with respect to the hash value. The closer to uniform hash values, the less search time required for a query. When t...

Non-uniform sampling promises increased equivalent sampling rates with reduced overall hardware costs. Each device applying non-uniform sampling must use special circuits and architectures to achieve a correct and predictable sampling scheme with respect to time instant placement. The architecture of an ASIC implementation for non-uniform sampling varies with the application. Different boundary...

The paper tries to establish the uniform design concept for evolvable hardware based applications. Evolvable circuit is understood as a system component with ability to evolve. As demo example, a component "evolvable pixel predictor" is presented.
