Early Detection of Treatment's Side Effects: A Sequential Approach
… vaccination campaign, we developed an optimal sequential test that allows for the early detection of potential side effect(s). This test employs a rule to stop the vaccination process once the observed number of side effect incidents exceeds a certain (pre-determined) threshold. The optimality of …

Sequential confidence bands for densities
We propose a fully sequential procedure for constructing a fixed width confidence band for an unknown density on a finite interval and show the procedure has the desired coverage probability asymptotically as the width of the band approaches zero. The procedure is based on a result of Bickel and …

Estimation of a density function with applications to reliability
… for the development of a. recursive estimation procedure. The technique employed is the method of successive substitution in which the solution at each iteration is used to generate the next solution until convergence is achieved. Consequently, we call this estimator the iterative estimator. …

Integrated multi-disciplinary design of a sailplane wing
… and performance constraints. Two design procedures are investigated. The first, referred to as the iterative, sequential procedure, involves optimizing the aerodynamic design for maximum average cross-country speed at E1 constant structural weight, and then optimizing the the structural …

Construction of Some Unbalanced Designs for the Partition Problem
… the partition problem. A two-stage and a purely sequential procedure are introduced which take c observations from the control population from the control population for each observation from each of the non-control population. The theoretical second-order asymptotics of the two introduced …

Effective Estimation of Marginal Quantiles in Steady-State Simulations
… formulation of the theoretical foundations for procedures based on Standardized Time Series (STS) for estimating steady-state quantiles with confidence intervals having given coverage probability and, potentially precision; and (2) the development and experimental evaluation of three automated …

Robust design and tolerancing of compressor blades
… and manufacturing tolerances is compared to a sequential procedure where the nominal blade geometry is optimized first, followed by the tolerances. Single-point optimization, where the performance at a single flow incidence is optimized, is found to produce geometries that are not robust to …

A comprehensive optimization methodology for strategic environmental sensor station locations
… rates in adverse weather. First, a sequential procedure is devised to identify the required number of stations for the region. Then, optimal weather station locations are identified using a genetic algorithm. The proposed approach is especially suited for optimizing region-wide ESS …

Some sequential estimation problems in logistic regression models
… accuracy and confidence level. In this work, a sequential procedure is proposed to overcome this difficulty. The procedure is shown to be asymptotically consistent and efficient. That is to say, as d approaches 0 the coverage probability converges to the required confidence level and the ratio …

Regulating the environmental impacts of the electricity supply industry.
… versatility, practicality and a step-by-step, sequential procedure for dealing appropriately with environmental impacts.The EAVA Framework encompasses four separate methods which have been developed simultaneously to work together in order to address different areas of the problem. The output …

Technology Enabled Assessments: An Investigation of Scoring Models for Scaffolded Tasks
… from those models from a validity perspective. A sequential procedure for fitting and evaluating increasingly complex models was conducted. Specifically, a baseline model that did not account for any scaffolding features in the assessment system was established and compared to three additional …

Sequential extraction of Cu from soil components and Cu-amended soils
… research were to evaluate reagents for use in a procedure to fractionate Cu in soils and to apply this methodology to soil incubated in the laboratory with added CuSO₄ or high-Cu swine manure. The evaluation procedure consisted of measuring desorption of Cu from a selection of clay minerals, …

Advancements in test security: preventive test assembly methods and change-point detection of compromised items in adaptive testing
… this chapter proposes a modified ATA procedure called common block assembly (CBA), which uses a stratified shadow-test approach to construct item blocks that are subsequently pieced together into full forms. Based on a previously operational item pool with an extended set of …
