Application of vibration-based damage detection techniques to civil infrastructure : incorporating uncertainty quantification
… damage detection algorithms. Instrumentation errors and variable environmental and operational conditions were identified as sources of uncertainties. It was established that in order to ensure reliability of the damage detection techniques and to assess their robustness, a damage detection …

Effectiveness of manual gesture treatment on residual /r/ articulation errors
… disorder, American English /r/ articulation errors, presents a unique and confounding clinical challenge as "therapy resistant" residual errors persist into adolescence and adulthood in many cases. Finding paucity of empirical research for /r/ treatment, evidence-based practice (EBP) …

Grid adaptation for functional outputs of compressible flow simulations
… functional can be directly related to the local residual errors of both the primal and adjoint solutions. This relationship allows local error contributions to be used as indicators in a grid adaptive method designed to produce specially tuned grids for accurately estimating the chosen …

A pseudo-Bayesian model-based approach for noninvasive intracranial pressure estimation
… plausible ICP values, and the resulting residual errors are transformed into likelihoods for each candidate ICP. The likelihoods are combined with a imulti-modal prior distribution of the ICP to yield an a posteriori distribution whose mode is taken as the final ICP estimate. An extension …

Follow-Up of College Students with a History of Developmental Speech Disorders
… of an articulation disorder involving isolated "residual" phoneme errors (RE) and 16 control subjects. Subjects were administered an experimental battery designed to tax the phonological system. Measures included conventional and pseudo-word spelling, syllabification, nonsense word repetition, …

Radiation therapy treatment plan optimization accounting for random and systematic patient setup uncertainties
… patient alignment is not perfect and results in residual errors in patient setup. The standard technique for dealing with errors in patient setup is to expand the volume of the target by some margin to ensure the target receives the planned dose in the presence of setup errors. This work develops …

Numerical solution of nonlinear algebraic systems in building energy modeling
… each step to reduce some vector norm of the residual errors, usually the convenient and tractable sum of squares. Unfortunately, the descent requirement subjects the solver to difficulties typically associated with function minimization-- stagnation, and convergence to local minima. The …

Co-calibration of self-reported measures of Pain Interference: the Patient Reported Outcomes Measurement Information System and the Brief Pain Inventory
… in the validation dataset. With respect to residual errors from the equating procedure, approximately 80% of the predicted scores in the developmental sample were within 4 points difference (<1/2 sd) of their respective PROMIS-PI SF scores, and 70% were within 4 points in the validation …

Fault monitoring in hydraulic systems using unscented Kalman filter
… estimates the iii system states with acceptable residual errors. Therefore, the structure is verified to be employed as the fault diagnosis scheme. Five types of faults are investigated in this thesis: loss of load, dynamic friction load, the internal leakage between the two hydraulic cylinder …

Recent numerical techniques for differential equations arising in fluid flow problems
… the finite difference method and the weighted residual method. Thirdly, we use the BSQLM to study numerically the boundary layer flow of a third grade non-Newtonian fluid past a vertical porous plate. We use the Jeffrey fluid as a typical fluid which shows non-Newtonian characteristics. …

Development of risk-based groundwater operating rules: a case study of Siloam Village, South Africa
… they had generally good model fits and low mean residual errors. Heterogeneous aquifer types were identified though leaky aquifer dominated. Storativity, transmissivity and hydraulic conductivity values ranged from 0.0003-0.060, 0.78-12.3 m2/day and 0.074-0.460 m/day, respectively, indicating …

Optimization of Image Guided Radiation Therapy for Lung Cancer Using Limited-angle Projections
… deformation is applied to further correct the residual errors from motion modeling. Using the XCAT phantom, a lung patient with a 30 mm diameter tumor was simulated to have various anatomical and respirational variations from the planning 4D-CT to on-board 4D-CBCTs, including respiration …
