The UAS industry is experiencing a rapid expansion, doubling every year since 2013, as adopters of this disruptive technology find new ways to benefit from these aerial platforms (Spencer, 2018). Of particular interest is the use of small to medium sized UASs, with a cost to the user of less than $2,000 that are the catalyst for this growth. Despite this rapid growth, UAS operators claim an inability to use these systems to their full potential due to regulatory obstacles. A collection of industry experts were interviewed to discuss the UAS industry, and to explore these perceived obstacles that may be hindering an increased use of these systems across the United States. Represented in the body of 12 interviewees were UAS operators, academic experts, UAS reporters, and legal and regulatory professionals from across the country with on average at least five years of experience in UASs, and at least 10 years in aviation to provide a breadth of experience and array of viewpoints.

This special issue of the Industrial and Systems Engineering Review once again showcases the top papers from the annual General Donald R. Keith memorial capstone conference at the United States Military Academy in West Point, NY.  After consideration of over 40 academic papers, the eight listed in this issue were selected for publication in this journal.  Topics addressed in the papers span a wide spectrum, however the distinguishing aspects of each paper included a common trend; each of these papers clearly implemented some aspect of systems or industrial engineering underpinned by thoughtful analysis.  The papers focus on three general bodies of knowledge:  systems engineering, modeling and simulation, and system dynamics modeling.Systems engineering topics included two unique contributions.  The work of Byers et. al examined the trades between weapon weight and weapon lethality.  Bares et. al. examined computing and storage needs of a simulation-intense analytical organization, considering the processing, storage, and growth that such an organization would need to consider as part of their IT solution. Three papers created unique contributions primarily through modeling and simulation studies.  Grubaugh et al. explored anomaly detection in categorical data, a notoriously difficult problem domain.  Bieger et al. used discrete event simulation to analyze rail yard operations in support of military deployments.  Kumar and Mittal analyzed the feasibility and benefits of alternative organizational structures to support cyber defense, primarily using a value modeling approach.       Lastly, applied system dynamics modeling and research produced several outstanding papers, primarily across social science problems.  Led by the extensive advising efforts of Jillian Wisniewski, three of her students contributed notably.  Ferrer and Wisniewski used system dynamics to understand the growth of Boko Haram over the course of the last decade.  Riedlinger and Wisniewski applied system dynamics to better understand the replication of mass killings across the United States.  Lastly, Provaznik and Wisniewski explored the diffusion of news and information using system dynamics, analyzing important social problems created by echo chambers for ideologies. Please join me in congratulating our authors, especially the young undergraduate scholars that provided the primary intellectual efforts that created the contents of this issue.COL Paul F.

This chapter discusses wargaming, combat modeling, and simulation, as well as force sizing and other issues related to military operations and warfighting scenarios. It argues that the ultimate purpose of wargaming and modeling is to help a country like the United States decide what kind of military, and military budget, it needs — as well as when and how to decide to use force. The chapter examines simple models of combat, starting with Lanchester equations, derived by a British engineer early in the twentieth century. However, they do not account well for most types of modern warfare, so the chapter shifts to other models and emphasizes an approach modified from that of the late Trevor Dupuy, focused on air-ground combat. The chapter also studies naval combat, including amphibious assault, blockade operations, and nuclear exchange calculations. Ultimately, it concludes with a framework for analyzing progress, or the lack thereof, in counterinsurgency operations like those in Iraq and Afghanistan.

Prostate adenocarcinoma is the most common malignant tumor of men in the United States and is the third leading cause of death in men. Despite attempts at early detection, there will be 244,000 new cases and 44,000 deaths from the disease in the United States in 1995. Therapeutic progress against this disease is hindered by an incomplete understanding of prostate epithelial cell biology, the availability of human tissues for in vitro experimentation, slow dissemination of information between prostate cancer research teams and the increasing pressure to “ stretch” research dollars at the same time staff reductions are occurring.To meet these challenges, we have used the correlative microscopy (CM) and client/server (C/S) computing to increase productivity while decreasing costs. Critical elements of our program are as follows:1) Establishing the Western Pennsylvania Genitourinary (GU) Tissue Bank which includes >100 prostates from patients with prostate adenocarcinoma as well as >20 normal prostates from transplant organ donors.

In recent years it became apparent that we needed to improve productivity and efficiency in the Microscopy Laboratories in GE Plastics. It was realized that digital image acquisition, archiving, processing, analysis, and transmission over a network would be the best way to achieve this goal. Also, the capabilities of quantitative image analysis, image transmission etc. available with this approach would help us to increase our efficiency. Although the advantages of digital image acquisition, processing, archiving, etc. have been described and are being practiced in many SEM, laboratories, they have not been generally applied in microscopy laboratories (TEM, Optical, SEM and others) and impact on increased productivity has not been yet exploited as well.In order to attain our objective we have acquired a SEMICAPS imaging workstation for each of the GE Plastic sites in the United States. We have integrated the workstation with the microscopes and their peripherals as shown in Figure 1.

Every ten years, the United States “constructs” itself politically. On a decennial basis, U.S. Congressional districts are quite literally drawn, physically constructing political representation in the House of Representatives on the basis of where one lives. Why does the United States do it this way? What justifies domicile as the sole criteria of constituency construction? These are the questions raised in this article. Contrary to many contemporary understandings of representation at the founding, I argue that there were no principled reasons for using domicile as the method of organizing for political representation. Even in 1787, the Congressional district was expected to be far too large to map onto existing communities of interest. Instead, territory should be understood as forming a habit of mind for the founders, even while it was necessary to achieve other democratic aims of representative government.
