Walsh analysis, epistasis, and optimization problem difficulty for evolutionary algorithms
… problem difficulty for evolutionary algorithms. Walsh analysis can be used to quantify epistasis. In this dissertation Walsh analysis is developed in detail starting with the definitions for the Walsh transform. The epistasis of a polynomial is shown to be bounded by the degree of the polynomial …

Eclectic Compositional Styles in the Piano Works of Craig Walsh
Craig Walsh (b. 1971) is an American composer whose music has earned him a worldwide reputation. His versatile output includes electronic music, instrumental music and the combination of the two. While modernism and pop music engage his compositional attention, a wider variety of musical styles …

Description and Genesis of selected Glacial Deposits, Walsh County, North Dakota
<p>Glacial deposits and features in central Walsh County, North Dakota were investigated during the summer of 1965 to determine both their origin and their relationship to the history of glacial Lake Agassiz. The deposits included till and lake sediments exposed in cuts along the Park River, while …

A geomagnetic survey of Pembina, Grand Forks, and eastern Walsh counties, North Dakota
… Dakota: Pembina County, Grand Forks County, and Walsh County east of 98°W. longitude. The field data was contoured by computer using the SYMAP commercial computer program. Nine major and several minor magnetic anomalies were discovered. Trends present on the aeromagnetic map of Minnesota continue …

The role of Walsh structure and ordinal linkage in the optimisation of pseudo-Boolean functions under monotonicity invariance.
… 2-bit and 3-bit pseudo-Boolean functions. We use Walsh analysis to define concepts of necessary, unnecessary, and conditionally necessary interactions, and of Walsh families. This helps to make precise some existing ideas in the literature such as benign interactions. Many algorithms are invariant …

The Population Genetics of the Colonization of the Western United States by the Apple Maggot, Rhagoletis Pomonella (Walsh) (Diptera: Tephritidae)
The apple maggot fly, Rhagoletis pomonella (Diptera: Tephritidae), is native to eastern North America, but has recently been reported in various parts of the western United States. Larvae of the species infest a variety of fruits, but three hosts are of special interest. Hawthorns (Crataegus) are …

A new representation for binary or categorical-valued time series data in the frequency domain
… functions instead of sinusoidal functions. The WalshFourier analysis takes this approach using a square form of functions. The Walsh-Fourier analysis is based on the Walsh functions. The Walsh functions are a square form of functions that take on only two values + 1 and -1. But, unlike …

Adaptive Fourier Analysis For Unequally-Spaced Time Series Data
Fourier analysis, Walsh-Fourier analysis, and wavelet analysis have often been used in time series analysis. Fourier analysis can be used to detect periodic components that have sinusoidal shape; however, it might be misleading when the periodic components are not sinusoidal. Walsh-Fourier analysis …

Design and performance of CDMA codes for multiuser communications
Walsh and Gold sequences are fixed power codes and are widely used in multiuser CDMA communications. Their popularity is due to the ease of implementation. Availability of these code sets is limited because of their generating kernels. Emerging radio applications like sensor networks or multiple …

An algorithm for a dollar bill recognition system
… features are extracted from a two dimensional Walsh Transform of this matrix. The process of feature selection is based upon the standard deviations of the Walsh coefficients. These features are then used by a Sequential Classifier for classifying the bill.

Generalized discrete Fourier transform with non-linear phase : theory and design
… like discrete Fourier transform (DFT), Walsh transform, and Gold codes have been successfully used over several decades in various engineering applications, including discrete multi-tone (DMT), orthogonal frequency division multiplexing (OFDM) and code division multiple access (CDMA) …

Aspects of parallel topologies applied to digital transforms of discrete signals
… for the implementation of the discrete Walsh, cosine, Haar and D4 Daubauchies transforms, and to compare the operation of the parallel algorithms running on T800 Transputers with the equivalent serial von Neumann type algorithm. This thesis also examines the transformations of a number …

Complexity adaptation in video encoders for power limited platforms
… the VBS partitioning algorithm based on the Walsh Hadamard Transform (WHT) is presented. The key idea is to segment regions of an image as edges or flat regions based on the fact that prediction errors are mainly affected by edges. Secondly, a fast motion estimation algorithm called Fast …

Digital noise reconstruction with a quantum sensor
… the decoherence of a qubit sensor under a set of Walsh modulation sequences, the (arithmetic) auto-correlation of a stationary Gaussian noise that couples to the quantum sensor is directly reconstructed and the corresponding noise spectrum is then reconstructed through linear transformations …

Automatic Optimization of DSP Algorithms
… compared, using fast Fourier transform (FFT), Walsh-Hadama transform (WHT), discrete cosine transform (DCT) and discrete sine transform (DST) as the benchmarks, to those obtained by highly optimized implementations including FFTW and the WHT package. The results of this comparison show that the …

THE INFLUENCE OF SELF-EFFICACY IN THE RELATIONSHIP BETWEEN VARIANTS OF SELF-BLAME AND PSYCHOLOGICAL DISTRESS
… attributions are directly linked to distress (Walsh, & Foshee, 1998; Walsh & Bruce, 2011). More specifically, the type of self-blame (i.e., behavioral and characterological) an individual associates with their experienced sexual assault, may influence their perceptions of avoidability of future …
