All reversible circuits have an intrinsic advantage over traditional irreversible circuits, because the reduce power consumption. Due to this, reversible circuits have been a source of constant excitement and great enthusiasm in the scientific community. Reversible logic is highly useful in nanotechnology, low power design and quantum computing. This paper proposes a design for a faster adder u...

Window functions are used in the estimation of power spectra, [1] and bispectra [2] in order to ensure the consistency of the periodogram and the Fourier type bispectrum estimation methods. In this paper, a three dimensional optimum bias lag window function is introduced in the estimation of the fourth order cumulant spectrum, also called trispectrum, which is estimated from the three dimesiona...

This paper proposes an architecture for implementing a self-checking 4-bit carry select adder that can be extended to any n-bit addition. The overhead is directly proportional to the number of transistors in the adder.

Abs ' t rae t In this paper , a class of algori thms for the problem of system identification in ~ are investigated. These algorithms are characterized by a two-stage structure and involve a class of window functions. Some conditions in terms of properties of the window functions are derived, which guarantee robust convergence of the algorithms. Identification errors are analyzed for several co...

The aim of this project was to optimise selection indices for efficient lean meat growth. Traditionally, genetic improvement of lean meat growth and feed efficiency has been based on ad libitum feeding. However, selection for lean meat growth and feed conversion ratio under ad libitum feeding has led to a reduction in feed intake in modern genotypes to the extent that feed intake is often not s...

reconnaissance drought index (rdi) is based on fitting a log-normal distribution to the ratio of precipitation to evapotranspiration (eto) values in selected periods. in this index value of eto were calculated based on mean temperature by thorenth-waite (th) method. th method, may underestimated eto values comparing to the actual in arid and semi arid regions. the log-normal distribution may no...

Genetic evolutionary algorithm is an effective and optimal test generation method. However, the method to select the algorithm parameters is often ad hoc relying on empirical data. We use Markov-based method to model the genetic evolutionary test generation process, parameterise the process characteristics, and derive analytical solutions for selecting the optimisation parameters. The method el...
