Introduction Several self-navigation techniques have been proposed to improve respiratory motion compensation in CMRA. Motion estimation is, however, often impeded by static structures within the excited volume. In this work a 2D self-navigation (2DSN) method is proposed and implemented by using the dummy profiles of a 3D bSSFP sequence. To create 2DSN images we added phase encoding (PE) gradie...

In data exchange, data are materialised from a source schema to a target schema, according to suitable source-to-target constraints. Constraints are also expressed on the target schema to represent the domain of interest. A schema mapping is the union of the source-to-target and of the target constraints. In this paper, we address the problem of containment of schema mappings for data exchange,...

A model of industry speed of price adjustment is derived from firm pricing behaviours. The model is applied to quarterly two-digit Australian manufacturing data for the period 1985:3 to 2002:3. Initially, the industry speed of price adjustment is treated as a function of structural cross-section variables. The results suggest that the industry speed of price adjustment is positively related to ...

In this paper an emotionally justified approach for controlling sound with physiology is presented. Measurements of listeners’ physiology, while they are listening to recorded music of their own choosing, are used to create a regression model that predicts features extracted from music with the help of the listeners’ physiological response patterns. This information can be used as a control sig...

Purpose – The purpose of this paper is to present a comparative study on the impact of manufacturing strategies and resources on innovation performance in two newly industrialised countries in the South East Asian region, Thailand and Vietnam. Design/methodology/approach – A quantitative approach was employed. The survey data was drawn from 95 Thai and 44 Vietnamese middle or senior managers in...

C Maximum likelihood estimation C.1 Building the likelihoood function Let Θ = (Θ1; Θ2) = (σ , σ η, σ u, π; β1, λ1, β2, λ2, φ) be the vector of parameters. Let X = (x1,s,t, x2,s,t, r1,s,t, r2,s,t) be the vector of observables, with r2 = p2− p1 and r1 = p1. Let 1(x) be an indicator variable equal to 1 if the event x has occured, and 0 otherwise. Let g(x) be the standard normal PDF and G(x) the st...

Researchers in education and the social sciences make extensive use of linear regression models in which the dependent variable is continuous-valued while the explanatory variables are a combination of continuous-valued regressors and dummy variables. The dummies partition the sample into groups, some of which may contain only a few observations. Such groups may easily include enough outliers t...

This paper examines problems in studying the relationship between casinos and crime, with a focus on a recently published, infl uential study (Grinols and Mustard 2006) which concluded that casinos cause a signifi cant amount of county-level crime in the U.S. Five key issues are examined. First, the most serious problem with their analysis is that it uses a crime rate that excludes the visiting...
