Abstract

This paper investigated the effectiveness of using a Restaurant Week promotion to market a group of restaurants during a traditionally slow period in the calendar year for the city of New Orleans. A questionnaire was developed by the communications committee of the local restaurant association. The questionnaire included questions to ascertain why restaurants chose to participate in Restaurant Week. The results of the study showed that the Restaurant Week campaign was successful for the participating restaurants in several ways. Success was demonstrated in increase in sales, a better understanding of menu item sales, an awareness of the strongest days of promotion, and methods of making reservations. The majority of restaurants experienced an increase of sales up to 20%. For both lunch and dinner promotions, Friday ranked as the strongest day of the promotion. The use of Open Table increased as a means of making reservations during Restaurant Week.

Abstract

Purpose

A numerical model dedicated to external eddy current inspection of tubes has been developed using the volume integral method (VIM). The purpose of this paper is to suggest new discretization schemes based on non‐uniform B‐splines for the solution of the state equation with the method of moments (MoM).

Design/methodology/approach

VIM is a semi‐analytical approach providing fast and accurate results for the simulation of eddy current testing (ECT) of pieces with canonical geometries. The state equation derived with this formalism is solved using the Galerkin variant of the well‐known MoM.

Findings

This paper shows that an accuracy improvement is achieved in MoM by using B‐splines with degree 1 or 2 as projection functions in MoM instead of pulse functions. Moreover, comparisons between simulation results show that, for all ECT configurations tested, the use of degree 1 B‐splines is sufficient to get this improvement.

Originality/value

The use of B‐splines functions has already been proposed for MoM in the literature, but not in the framework of the Galerkin variant of MoM. This paper also shows quantitative comparisons between experiment and simulation as well as a study of the minimal degree required to get an accuracy improvement in MoM.

Abstract

A semi‐analytical integration technique to evaluate the singular integration in 3‐D boundary element method for electromagnetic field computation is reported. The technique has been applied in a hybrid finite element—boundary integral model to evaluate the singular integral terms when constructing the “outside stiffness matrix” in the case of small air‐gaps, and it has also been used to calculate the exterior magnetic field in the proximity of the boundaries. The comparison with the conventional Gaussian quadrature has been carried out by modelling a 3‐D magnetostatic problem with a small air‐gap.

Abstract

Purpose

This paper examines recent research on prejudice in the workplace by comparing the domains of management, psychology and sociology. It seeks to make recommendations regarding future research directions in light of significant social movements that impact on prejudice and discrimination.

Design/methodology/approach

The design is built on an interdisciplinary literature review, drawing from research in management, psychology and sociology. In total, 450 recent articles were examined. These factors related to the individual, group and organizational/societal level of analysis to determine what we know about prejudice and discrimination in the workplace and what we do not know.

Findings

This study’s findings show that each domain of management, psychology and sociology makes distinctive contributions, thus providing scholars with a holistic understanding of prejudice and discrimination in the workplace.

Research limitations/implications

The use of content analysis, using both automated and manual coding and chi-square analysis, allows for a deep understanding of the existing research in all three of the domains. This approach allows for reliability and replicability. Noted are the relative absence of intersectionality, immutability and salience.

Practical implications

Recommendations regarding future research directions in light of significant social movements that impact prejudicial attitudes and discriminatory behaviors at all three levels are provided.

Originality/value

The study utilized a novel approach in examining prejudice in the workplace taking a grounded theory perspective, allowing the existing literature to shape the focus and results of the study. Using NVivo allowed for drilling down into the content of the articles to identify minor and major points of discussion relating to prejudice.

Abstract

This paper presents a hybrid finite element — boundary element method for the steady state thermal analysis of energy installations. The coupling of the two techniques is presented: finite elements are used in a bounded region containing thermal sources while the complementary domain is treated with boundary elements. With such a combination the number of unknowns is reduced and an accurate prediction of temperature is obtained. As an example, the temperature rise is computed for the case of three power cables laid in a thermal backfill: the finite element method (FEM) is used for the cables and the backfill while the homogeneous soil is taken into account with the boundary element method (BEM).

Abstract

Presents a new method to compute simultaneously the near and the far field in electromagnetic 3D scattering problems. In this approach a bounded spherical domain contains all the inhomogeneous objects and divides the whole space into two different regions. In both regions the field is expressed as a linear expansion with the same unknown coefficients. Gives the field as an exact infinite expansion of vector spherical harmonics in the outer region. Computes the basis functions using finite elements in the inner region. Finally, obtains the coefficients of the two expansions by matching the inner and the outer fields on the spherical interface.

Abstract

Purpose

The purpose of this paper is to provide a new methodology for the characterization of a defect by eddy‐current testing (ECT). The defect is embedded in a conductive non‐magnetic plate and the measured data are the impedance variation of an air‐cored probe coil scanning above the top of the plate.

Design/methodology/approach

The inverse problem of defect characterization is solved by an iterative global optimization process. The strategy of the iterations is the kriging‐based expected improvement (EI) global optimization algorithm. The forward problem is solved numerically, using a volume integral approach.

Findings

The proposed method seems to be efficient in the light of the presented numerical results. Further investigation and comparison to other methods are still needed.

Originality/value

This is believed to be the first time when the EI algorithm has been used to solve an inverse problem related to the ECT.

Abstract

Purpose

In Laser Power Bed Fusion (LPBF), the process and operating parameters influence the mechanical and geometrical characteristics of the manufactured parts. Therefore, the optimization and control of these parameters are mandatory to improve the quality of the produced parts. During manufacturing, the process parameters are usually constant whatever the part size or the built layer. With such settings, the manufacturing process may lead to an inhomogeneous thermal behavior and locally overheating areas, impacting the part quality. The aim of this study is to take advantage of an analytical thermal model to modulate the laser power upstream of manufacturing.

Design/methodology/approach

The approach takes place in two steps: the first step consists in calculating the preheating temperature at the considered point and the second one determines the power modulation of the laser to reach the desired temperature at this point.

Findings

Numerical investigations on several use cases show the effectiveness of the method to control the overheated areas and to homogenize the simulated temperature distribution.

Originality/value

The specificity of this model lies in its ability to directly calculate the amount of energy to be supplied without any iterative calculation. Furthermore, to be as close as possible to the technology used on LPBF machines, the kinematic behavior of the scanning head and the laser response time are also integrated into the calculation.
