Abstract

The study of arms control and disarmament is a subject of renewed interest in the United States. The attention of academicians, politicians, and average citizens, focused by a fear of nuclear holocaust, has turned to questions of how best to seek peace and safety in the nuclear age. Courses and programs devoted to arms control and disarmament and methods of achieving peaceful resolution of conflicts in today's world are offered at all educational levels, and the general public, aware of the necessity of being well‐informed on such an important topic, is looking for ways to obtain factual and reliable information to help sort out the conflicting claims of political spokespeople. Such material does exist and should be available to researchers, professors, students, and citizens, so that they can form opinions and attempt to influence policy on the basis of a sound understanding.

Abstract

Arms control, international security, and peace are topics of growing concern among scholars. This concern is a reaction to the heightened international tensions during the past decade. Researchers are aware that their work might contribute to an understanding of the sources of conflict, and to the peaceful resolution of international issues. Interest in the field is rapidly expanding both in the United States and abroad, but there has been little agreement on the direction research should take. Research institutes, think‐tanks, and university programs around the world are devoting an increasing amount of time to the study of arms control, international security, and peace.

Abstract

Gives a bibliographical review of the finite element methods (FEMs) applied for the linear and nonlinear, static and dynamic analyses of basic structural elements from the theoretical as well as practical points of view. The range of applications of FEMs in this area is wide and cannot be presented in a single paper; therefore aims to give the reader an encyclopaedic view on the subject. The bibliography at the end of the paper contains 2,025 references to papers, conference proceedings and theses/dissertations dealing with the analysis of beams, columns, rods, bars, cables, discs, blades, shafts, membranes, plates and shells that were published in 1992‐1995.

Abstract

THE Electronic Computer Exhibition and the B.I.M. conference have provided material for serious contemplation. Sir Harold Gillett, Lord Mayor of London, opening the Exhibition suggested that we are living in the age of the second industrial revolution. There are some who share the Lord Mayor's view and others who take the whole matter in their stride. One thing is certain, we shall be able to do more—and do it more efficiently.

Abstract

Purpose

Women in prison throughout the world experience higher rates of mental and physical illness compared with the general population and compared with men in prison. The paper finds no published studies that report on men or women in prison engaging in participatory health research to address their concerns about nutrition and fitness. The purpose of this paper is to describe a pilot nutrition and fitness program, which resulted from a unique prison participatory health research project.

Design/methodology/approach

Women in prison designed, led, and evaluated a six-week pilot fitness program in a minimum/medium security women's prison. Pre- and post-program assessments included a self-administered questionnaire and body measures. Open-ended questionnaire responses illuminated the quantitative findings.

Findings

Sixteen women in prison completed the program evaluation. Weight, body mass index, waist-to-hip ratio, and chest measurements decreased, and energy, sleep, and stress levels improved by the end of the program.

Research limitations/implications

As a component of a participatory research project, incarcerated women designed and led a nutrition and fitness program, which resulted in improved body measures and self-reported health benefits.

Originality Value

Incarceration provides opportunities to engage women in designing their own health programs with consequent potential long-term “healing” benefits.

Abstract

Purpose

Multidisciplinary design frameworks elaborated for aeronautical applications require considerable computational power that grows enormously with the utilization of higher fidelity tools to model aeronautical disciplines like aerodynamics, loads, flight dynamics, performance, structural analysis and others. Surrogate models are a good alternative to address properly and elegantly this issue. With regard to this issue, the purpose of this paper is the design and application of an artificial neural network to predict aerodynamic coefficients of transport airplanes. The neural network must be fed with calculations from computational fluid dynamic codes. The artificial neural network system that was then developed can predict lift and drag coefficients for wing-fuselage configurations with high accuracy. The input parameters for the neural network are the wing planform, airfoil geometry and flight condition. An aerodynamic database consisting of approximately 100,000 cases calculated with a full-potential code with computation of viscous effects was used for the neural network training, which is carried out with the back-propagation algorithm, the scaled gradient algorithm and the Nguyen–Wridow weight initialization. Networks with different numbers of neurons were evaluated to minimize the regression error. The neural network featuring the lowest regression error is able to reduce the computation time of the aerodynamic coefficients 4,000 times when compared with the computing time required by the full potential code. Regarding the drag coefficient, the average error of the neural network is of five drag counts only. The computation of the gradients of the neural network outputs in a scalable manner is possible by an adaptation of back-propagation algorithm. This enabled its use in an adjoint method, elaborated by the authors and used for an airplane optimization task. The results from that optimization were compared with similar tasks performed by calling the full potential code in another optimization application. The resulting geometry obtained with the aerodynamic coefficient predicted by the neural network is practically the same of that designed directly by the call of the full potential code.

Design/methodology/approach

The aerodynamic database required for the neural network training was generated with a full-potential multiblock-structured code. The training process used the back-propagation algorithm, the scaled-conjugate gradient algorithm and the Nguyen–Wridow weight initialization. Networks with different numbers of neurons were evaluated to minimize the regression error.

Findings

A suitable and efficient methodology to model aerodynamic coefficients based on artificial neural networks was obtained. This work also suggests appropriate sizes of artificial neural networks for this specific application. We demonstrated that these metamodels for airplane optimization tasks can be used without loss of fidelity and with great accuracy, as their local minima might be relatively close to the minima of the original design space defined by the call of computational fluid dynamics codes.

Research limitations/implications

The present work demonstrated the ability of a metamodel with artificial neural networks to capture the physics of transonic and subsonic flow over a wing-fuselage combination. The formulation that was used was the full potential equation. However, the present methodology can be extended to model more complex formulations such as the Euler and Navier–Stokes ones.

Practical implications

Optimum networks reduced the computation time for aerodynamic coefficient calculations by 4,000 times when compared with the full-potential code. The average absolute errors obtained were of 0.004 and 0.0005 for lift and drag coefficient prediction, respectively. Airplane configurations can be evaluated more quickly.

Social implications

If multidisciplinary optimization tasks for airplane design become more efficient, this means that more efficient airplanes (for instance less polluting airplanes) can be designed. This leads to a more sustainable aviation.

Originality/value

This research started in 2005 with a master thesis. It was steadily improved with more efficient artificial neural networks able to handle more complex airplane geometries. There is a single work using similar techniques found in a conference paper published in 2007. However, that paper focused on the application, i.e. providing very few details of the methodology to model aerodynamic coefficients.

Abstract

The US feminist art movement of the 1970s is examined through selected works written by artists, critics, and historians during the 1990s. Books, exhibition catalogues, dissertations, and articles place the movement within the broader contexts of art history and criticism, women’s history, and cultural studies. The art includes painting, drawing, collage, mixed‐media, graphics, installations, video, and performance. An increasing historical perspective allows scholars to examine the movement’s institutions and unresolved issues surrounding class, race, and sexual preference. Background is provided by an introductory essay, which summarizes the movement’s facets of protest, pedagogy, networks and professional associations, and art making while noting examples of publications and institutions that form part of the record of the movement. This article will be useful to librarians and scholars in art, women’s studies, history, sociology, and cultural studies.
