Rank/Activity: A Canonical Form for Binary Resolution

چکیده

The rank/activity restriction on binary resolution is introduced. It accepts only a single derivation tree from a large equivalence class of such trees. The equivalence classes capture all trees that are the same size and differ only by reordering the resolution steps. A proof procedure that combines this restriction with the authors’ minimal restriction of binary resolution computes each minimal binary resolution tree exactly once.

VHDL Implementation of Multiplierless, High Performance DWT Filter Bank

operation canonical sign digit plays an important roll in processing signal. Advantage of this implementation is to reduce the number of adders in hardware and also increase the speed of operation. Filter bank filters the low resolution information using lowpass filter and high resolution information by using high pass filter. Wavelet coefficient decides the characteristic of filter. In this me...

Dominant Association Species in Binary Mixtures of Methanol, Ethanol and Propanol in Nonpolar Solvents

The molecular associations in the binary mixtures of (methanol/solvent), (ethanol/solvent) and (propanol/solvent) were studied using NMR, FTIR and VLE data at different temperatures. The activity coefficients as the most important quantities representing the mixture deviation form ideal behavior were evaluated by using various association models to express the physical and chemical contribution...

Using independent open-to-closed transitions to simplify aggregated Markov models of ion channel gating kinetics.

Deducing plausible reaction schemes from single-channel current traces is time-consuming and difficult. The goal is to find the simplest scheme that fits the data, but there are many ways to connect even a small number of states (>2 million schemes with four open and four closed states). Many schemes make identical predictions. An exhaustive search over model space does not address the many equ...

Determining the order of minimal realization of descriptor systems without use of the Weierstrass canonical form

A common method to determine the order of minimal realization of a continuous linear time invariant descriptor system is to decompose it into slow and fast subsystems using the Weierstrass canonical form. The Weierstrass decomposition should be avoided because it is generally an ill-conditioned problem that requires many complex calculations especially for high-dimensional systems. The present ...
