An integrated modal approach to surface and volume scattering in ocean acoustic waveguides
… field are calculated. Numerical results show the modal formulation agrees well with Kuperman and Schmidt's model, while reducing computation times by several orders of magnitude for the scenarios considered. Next, a perturbation theory describing scattering from sound speed and density …

An analysis of the self-evaluation strategy of reading one's drafts aloud as an aid to revision : a multi-modal approach
This mixed model study informed by a multi-modal approach investigated the relationship between reading aloud and the student revision process. Participants for this study were undergraduate juniors and seniors enrolled in any one of four sections of English 393 (Writing Competency Course) at Ball …

Development of a Competency-Based "Boot Camp" Curriculum for the PGY-1 Neurology Residents
… on a targeted needs assessment. Methods: A multi-modal approach has been used to assess both self-reported and objective learning needs including: ITER review, an online survey of the key stakeholders, and a consensus meeting at the University of Calgary. Results: This study highlighted the need …

Historic Preservation Approaches for the City of Arroyo Grande
… and inappropriate alterations. Through a multi-modal approach, this project seeks to find ways that structures can be preserved. The project looks at how the federal, state and local governments deal with historic properties. It then provides information on how local governments can protect …

Syntactic variation in Afrikaans : an empirical study
… (sociolinguistics), the methodology follows a bi-modal approach. Both performance and competence are considered, and arguments are based on two types of data: speech data (interviews, narrative picture descriptions) and grammaticality judgements (elicited by means of an oral questionnaire). …

a/r/t + design: one designer’s experience as a/r/tographer
… negotiated in and through practice. This multi-modal approach linked reflective analysis with the creative practice of a visual artist and commercial designer to uncover the ideal conditions for creativity, discovering that a/r/t + design roles are not clearly defined or easily labelled. The …

Validation of dMRI techniques for mapping brain pathways
… accurate? We tackle these questions with a multi-modal approach that capitalizes on the complementary strengths of available validation strategies to probe dMRI performance on different scales and across a wide range of acquisition and analysis parameters. The outcome is a multi-layered validation …

Identification and evaluation of biomarkers for Huntington’s disease
… A robust panel of biomarkers from a number of modalities will be necessary to progress to interventional clinical trials of disease-modifying therapies in HD, using biomarkers to measure the success or failure of an intervention. Such cross-validation requires simultaneous multimodal biomarker …

A Quadratic Non-Linear Elasticity Formulation for the Dynamic Behaviour of Fluid-Loaded Structures
… larger displacements. By extending the standard modal decomposition technique for linear structural analysis, the governing equations and boundary conditions are updated to account for the leading-order non-linear terms and a new modal formulation with quadratic modes is derived. The quadratic …

A modal method for the simulation of nonlinear dynamical systems with application to bowed musical intruments
… modelling computational method based on a modal approach is developed to perform simulations of nonlinear dynamical systems with particular application to friction-excited musical instruments. This computational method is applied here to three types of systems: bowed strings as the violin …

Mass flow measurement of multi-phase mixtures by means of tomographic techniques
… Impedance tomography can be described as a dual-modal approach since both the capacitance and conductance of the different electrode combinations are measured to reconstruct the omplex impedance of the material distribution. Previous research has shown that impedance tomography can be used to …
