Abstract:

Although the actions of others can influence a consumer's behavior, these actions are often at odds with performance norms. For example, charities can experience relatively low rates of support (resulting in a negative deviation from a performance norm) or relatively high rates of support (resulting in a positive deviation from a performance norm). Previous research provides evidence of the equivocal effects of these deviations, with both positive and negative deviations motivating prosocial behaviors. The current research reconciles these competing findings by introducing construal as a moder

Abstract:

A method for defining which parts of a combined cycle gas turbine (CCGT) power plant are responsible for performance deviations is presented. When the overall performances deviate from their baseline values, application of the method allows the determination of the component(s) of the plant, responsible for this deviation. It is shown that simple differentiation approaches may lead to erroneous conclusions, because they do not reveal the nature of deviations for individual components. Contributions of individual components are then assessed by separating deviations due to permanent changes and

Abstract:

Abstract Subsolutions to the Hamilton–Jacobi–Bellman equation associated with a moderate deviations approximation are used to design importance sampling changes of measure for stochastic recursive equations. Analogous to what has been done for large deviations subsolution-based importance sampling, these schemes are shown to be asymptotically optimal under the moderate deviations scaling. We present various implementations and numerical results to contrast their performance, and also discuss the circumstances under which a moderate deviation scaling might be appropriate.

Abstract:

Gear tooth flank deviations should be characterized to evaluate individual gear accuracy directly linked to gear performance during engagement. The comprehensive pitch deviation representation we propose is calculated using multiple tooth flank surface deviations as 0-order form deviations. In this representation, pitch error is expressed by angle unit, not by length unit, and calculated from measured conventional deviation (profiles and leads) withoutmeasuring pitch deviation. For spur and helical gears, pitch deviation is expressed by a single length unit and also by a single angle unit. On

Abstract:

When designing a magnetic levitation system it is assumed that the magnets are ideally magnetized. In practice, however, this is not the case and deviations occur in the magnetization. In this paper two types of deviations are considered, namely a constant angular deviation and the magnetization error. Calculations show that a constant error has larger impact on the performance of a gravity compensator than the magnetization error.

Abstract:

There has been recent incentive for understanding the possible deleterious effects that manufacturing deviations can have on compressor blade performance. This is of particular importance in todayâ s age, as compressor designs are pushing operating limits by employing fewer stages with higher loadings and are designed to operate at ever higher altitudes. Deviations in these advanced, as well as legacy designs, could negatively affect the performance and operation of a core compressor; thus, a numerical investigation to quantify manufacturing deviations and their effects is undertaken.

Abstract:

By construction, actively managed portfolios must differ from passively managed ones. Consequently, the manager’s problem can be viewed as selecting how to deviate from a passive portfolio composition. The purpose of this study is to see if we can infer the presence of superior skills through the analysis of the portfolio deviations from a benchmark. Based on the Black-Litterman approach, we hypothesize that positive signals should lead to an increase in weight, from which should follow that the largest deviations from a benchmark weight reveal the presence of superior skills.

Abstract:

AbstractThis paper presents and investigates a cyber-physical fabrication workflow, which can respond to the deviations between built- and designed form in real-time with vision augmentation. We apply this method for large scale structures built from natural bamboo poles. Raw bamboo poles obtain evolutionarily optimized fibrous layouts ideally suitable for lightweight and sustainable building construction. Nevertheless, their intrinsically imprecise geometries pose a challenge for reliable, automated construction processes. Despite recent digital advancements, building with bamboo poles is still a labor-intensive task and restricted to building typologies where accuracy is of minor importance. The integration of structural bamboo poles with other building layers is often limited by tolerance issues at the interfaces, especially for large scale structures where deviations accumulate incrementally. To address these challenges, an adaptive fabrication process is developed, in which existing deviations can be compensated by changing the geometry of subsequent joints to iteratively correct the pose of further elements. A vision-based sensing system is employed to three-dimensionally scan the bamboo elements before and during construction. Computer vision algorithms are used to process and interpret the sensory data. The updated conditions are streamed to the computational model which computes tailor-made bending stiff joint geometries that can then be directly fabricated on-the-fly. In this paper, we contextualize our research and investigate the performance domains of the proposed workflow through initial fabrication tests. Several application scenarios are further proposed for full scale vision-augmented bamboo construction systems.

Abstract:

A fast method is presented for evaluating the impact of blade manufacturing variations on the aerodynamic performance of turbomachines. The method consists of two parts. Firstly, an adjoint method is developed to evaluate the aerodynamic sensitivities for multistage turbomachines. This sensitivity information may then be used to perform fast direct Monte Carlo simulations to obtain the statistical distribution of the variations of aerodynamic performances resulting from any given set of manufacturing variations. Secondly, a method is developed to construct reduced-order models for the three-di

Abstract:

This paper presents a method for detecting deterioration of turbomachinery in pipeline service. Many pipeline compressors have data logging systems, but do not fully exploit the resulting data. This paper describes a method to predict how expected values for turbomachinery performance parameters vary with conditions, and provides options for assessing the severity of deviations between measured and expected values. Parameters considered include: centrifugal compressor discharge pressure, centrifugal compressor thermal efficiency, fuel flow, turbocharger speed, axial compressor discharge pressu

Abstract:

Successful compressor aerodynamic performance can be achieved by satisfactory completion of requirements in the following three areas: aerodynamic design quality of blading manufacturing and assembly of the components Using presently available computer programs capable of doing detailed three dimensional analysis of the flow field, it is possible to obtain excellent aerodynamic designs exceeding 90% isentropic efficiency. When the design requirements are deviated from the manufacturing process, the result will be less than optimum performance, for example: inadequate surge margin, lowered effi

Abstract:

This paper reports on a two-tiered experiment designed to separately identify the selection and effort margins of pay-for-performance (P4P). At the recruitment stage, teacher labor markets were randomly assigned to a pay-for-percentile or fixed-wage contract. Once recruits were placed, an unexpected, incentive-compatible, school-level re-randomization was performed, so that some teachers who applied for a fixed-wage contract ended up being paid by P4P, and vice versa. By the second year of the study, the within-year effort effect of P4P was 0.16 standard deviations of pupil learning, with the

Abstract:

Over 400 billion passenger vehicle trajectory waypoints are collected each month in the United States. This data creates many new opportunities for agencies to assess operational characteristics of roadways for more agile management of resources. This study compared traffic counts obtained from 24 Indiana Department of Transportation traffic counts stations with counts derived by the vehicle trajectories during the same periods. These stations were geographically distributed throughout Indiana with 13 locations on interstates and 11 locations on state or US roads. A Wednesday and a Saturday in

Abstract:

The learning crisis in developing countries is increasingly acknowledged (World Bank, 2018). The UN’s Sustainable Development Goals (SDG) include goals and targets for universal learning and the World Bank has adopted a goal of eliminating learning poverty. We use student level PISA-D results for seven countries (Cambodia, Ecuador, Guatemala, Honduras, Paraguay, Senegal, and Zambia) to examine inequality in learning outcomes at the global, country, and student level for public school students. We examine learning inequality using five dimensions of potential social disadvantage measured in PIS
