    The U.S. Army as a Rational Economic Agent: The Choice of Draft Animals during the Civil War

    The Army has historically been ridiculed as an inefficient institution which neither responds to incentives, nor acts as a rational economic agent. This paper argues that historically there were instances in which the army acted in ways analogous to "market driven" institutions. During the Civil War the Army tried to issue the more abuse-resistant, yet more expensive, mule to its soldiers instead of a less expensive substitute, the horse. It is argued that this practice was to mute the effects of agency problems, as was done in southern agriculture and in U.S. mining. This finding has implications for the Army today, as well as for other institutions with similar agency problems, that issue physical capital to their agents.Soldiers; War

    Non-GNSS Smartphone Pedestrian Navigation Using Barometric Elevation and Digital Map-Matching

    Get PDF
    Pedestrian navigation in outdoor environments where global navigation satellite systems (GNSS) are unavailable is a challenging problem. Existing technologies that have attempted to address this problemoften require external reference signals or specialized hardware, the extra size,weight, power, and cost of which are unsuitable for many applications. This article presents a real-time, self-contained outdoor navigation application that uses only the existing sensors on a smartphone in conjunction with a preloaded digital elevation map. The core algorithm implements a particle filter, which fuses sensor data with a stochastic pedestrian motion model to predict the user’s position. The smartphone’s barometric elevation is then compared with the elevation map to constrain the position estimate. The system developed for this research was deployed on Android smartphones and tested in several terrains using a variety of elevation data sources. The results fromthese experiments showthe systemachieves positioning accuracies in the tens of meters that do not grow as a function of time

    Multi-objective Database Queries in Combined Knapsack and Set Covering Problem Domains

    Database queries are one of the most important functions of a relational database. Users are interested in viewing a variety of data representations, and this may vary based on database purpose and the nature of the stored data. The Air Force Institute of Technology has approximately 100 data logs which will be converted to the standardized Scorpion Data Model format. A relational database is designed to house this data and its associated sensor and non-sensor metadata. Deterministic polynomial-time queries were used to test the performance of this schema against two other schemas, with databases of 100 and 1000 logs of repeated data and randomized metadata. Of these approaches, the one that had the best performance was chosen as AFIT’s database solution, and now more complex and useful queries need to be developed to enable filter research. To this end, consider the combined Multi-Objective Knapsack/Set Covering Database Query. Algorithms which address The Set Covering Problem or Knapsack Problem could be used individually to achieve useful results, but together they could offer additional power to a potential user. This paper explores the NP-Hard problem domain of the Multi-Objective KP/SCP, proposes Genetic and Hill Climber algorithms, implements these algorithms using Java, populates their data structures using SQL queries from two test databases, and finally compares how these algorithms perform

    Federal Forest Restoration Program use of the Good Neighbor Authority : 2016-2021 activities and outcomes

    Get PDF
    2 pagesRestoration is a pressing need across Oregon’s forests—over 7 million acres are experiencing declining forest health and are at elevated risk of large and destructive wildfires. Oregon Department of Forestry’s (ODF) Federal Forest Restoration Program partners with federal agencies to restore and steward these important lands to enhance and protect the valuable benefits they provide for Oregonians. ODF supports three key elements of restoration: Planning – Implementation – Monitoring, all integral to restoring land in an ecologically sound, scientific manner. This fact sheet summarizes the results of ODF’s efforts to increase the pace, scale and quality of restoration on federal lands in Oregon.Funded by Oregon Department of Forestry

    FAST: FAST Analysis of Sequences Toolbox.

    Get PDF
    FAST (FAST Analysis of Sequences Toolbox) provides simple, powerful open source command-line tools to filter, transform, annotate and analyze biological sequence data. Modeled after the GNU (GNU's Not Unix) Textutils such as grep, cut, and tr, FAST tools such as fasgrep, fascut, and fastr make it easy to rapidly prototype expressive bioinformatic workflows in a compact and generic command vocabulary. Compact combinatorial encoding of data workflows with FAST commands can simplify the documentation and reproducibility of bioinformatic protocols, supporting better transparency in biological data science. Interface self-consistency and conformity with conventions of GNU, Matlab, Perl, BioPerl, R, and GenBank help make FAST easy and rewarding to learn. FAST automates numerical, taxonomic, and text-based sorting, selection and transformation of sequence records and alignment sites based on content, index ranges, descriptive tags, annotated features, and in-line calculated analytics, including composition and codon usage. Automated content- and feature-based extraction of sites and support for molecular population genetic statistics make FAST useful for molecular evolutionary analysis. FAST is portable, easy to install and secure thanks to the relative maturity of its Perl and BioPerl foundations, with stable releases posted to CPAN. Development as well as a publicly accessible Cookbook and Wiki are available on the FAST GitHub repository at https://github.com/tlawrence3/FAST. The default data exchange format in FAST is Multi-FastA (specifically, a restriction of BioPerl FastA format). Sanger and Illumina 1.8+ FastQ formatted files are also supported. FAST makes it easier for non-programmer biologists to interactively investigate and control biological data at the speed of thought
