In the field of nanofabrication, engineers often face unique challenges in resource‐limited experimental budgets, the sensitive nature of process behavior with respect to controllable variables, and highly demanding tolerance requirements. To effectively overcome these challenges, this article proposes a methodology for a sequential design of experiments through batches of experimental runs, aptly named Layers of Experiments with Adaptive Combined Design (LoE/ACD). In higher layers, where process behavior is less understood, experimental regions cover more design space and data points are more spread out. In lower layers, experimental regions are more focused to improve understanding of process sensitivities in a local, data‐rich environment. The experimental design is a combination of a space‐filling and an optimal design with a tuning parameter that is dependent on the amount of information accumulated over the various layers. The proposed LoE/ACD method is applied to optimize a carbon dioxide (epet‐CO2) assisted deposition process for fabricating silver nanoparticles with pressure and temperature variables. © 2015 Wiley Periodicals, Inc.

Perceptions of Third World nations as susceptible to communist subversion and revolutionary warfare led the Eisenhower administration to formulate a coordinated internal security strategy known simply as ‘1290d’. Later renamed the Overseas Internal Security Program (OISP), this policy initiative sought to strengthen host‐nation security forces, judicial systems, and public information media in an effort to combat indirect communist intervention strategies. Implementing OISP policy in Latin America proved difficult. In Congress, the administration was criticised for colluding with dictatorial regimes, while Latin Americans feared that the new program would be used as a ‘Trojan Horse’ to penetrate their security structures. After the Cuban Revolution, however, OISP policies developed under Eisenhower came to dominate US‐Latin American security relations for the remainder of the Cold War. 相似文献

This article presents an approximate analytical method for evaluating an aircraft sortie generation process. The process is modeled as a closed network of multiserver queues and fork-join nodes that allow concurrent service activities. The model uses a variation of mean value analysis (MVA) to capture the effect of mean service times, resource levels, and network topology on performance measures including resource utilizations and the overall sortie generation rate. The quality of the analytical approximation is demonstrated through comparison with simulation results. © 1997 John Wiley & Sons, Inc. 1 This article is a US Government work and, as such, is in the public domain in the United States of America.

This paper presents an algorithm for solving the integer programming problem possessing a separable nonlinear objective function subject to linear constraints. The method is based on a generalization of the Balas implicit enumeration scheme. Computational experience is given for a set of seventeen linear and seventeen nonlinear test problems. The results indicate that the algorithm can solve the nonlinear integer programming problem in roughly the equivalent time required to solve the linear integer programming problem of similar size with existing algorithms. Although the algorithm is specifically designed to solve the nonlinear problem, the results indicate that the algorithm compares favorably with the Branch and Bound algorithm in the solution of linear integer programming problems. 相似文献

This paper presents a model for converting legacy defense production facilities into private‐sector economic resources. Specifically, this paper will examine as a case study the first successful conversion of a former U.S. Department of Energy nuclear weapons production installation, including reasons for its success, its costs and benefits, and lessons for public policy. It is envisioned that this model may be useful for mitigating local economic hardship resulting from defense “downsizing” and for privatizing production capacities critical for national defense. 相似文献

AbstractThe economics of stolen valor concerns the act of trading on false claims of being awarded valorous military service medals. The U.S. Supreme Court overturned the 2005 Stolen Valor Act, largely on First Amendment grounds. Misrepresentation that devalues the reputation of medals for valor may not violate the revised statute despite decreasing the wage premium and discouraging investment in military effort. 相似文献

This paper investigates the multivariate Polya distribution (MPD) for application in combat models for which enemy targets must be randomly assigned to fighting units. Six sets of actual combat data motivate the allocation model. Scenarios include air‐to‐air combat, tank, and submarine warfare. Goodness of fit tests are derived which verify the validity of the MPD, and reinforce the notion that multinomial allocation is too simplistic for such combat models. Simulations to determine optimal allocations for minimal combat cost are applied in order to illustrate the role of the MPD in combat modeling. © 2001 John Wiley & Sons,Inc.
