    Development of a low level autonomous machine

    An autonomous machine is a machine that can navigate through its environment without human interactions. These machines use sensors to sense the environment and have computing abilities for receiving and interpreting the sensory data as well as for controlling their displacement. At the University of Saskatchewan (Saskatoon, Canada), a low level autonomous machine was developed. This low level machine was the sensor system for an autonomous machine. The machine was capable of sensing the environment and carrying out actions based on commands sent to it. This machine provided a sensing and control layer, but the path planning (decision making) part of the autonomous machine was not developed.This autonomous machine was developed on a Case IH DX 34H tractor with the purpose of providing a machine for testing software and sensors in a true agricultural environment. The tractor was equipped with sensors capable of sensing the speed and heading of the tractor. A control architecture was developed that received input commands from a human or computer in the form of a target heading and speed. The control architecture then adjusted controls on the tractor to make the tractor reach and maintain the target heading and speed until a new command was provided. The tractor was capable of being used in all kinds of weather, although some minor issues arose when testing in rain and snow. The sensor platform developed was found to be insufficient for proper control. The control structure appeared to work correctly, but was hindered by the poor sensor platform performance

    Mirroring Atticus: A Text-Complexity Circle Highlights Unconventional Heroes

    Get PDF
    This article outlines the arrangement of a text circle in an eighth-grade English language arts class around the novel To Kill a Mockingbird. The author first provides rationale for examining Atticus Finch as a non-traditional hero for his going against the status quo despite consequence to do what's right. The author then establishes that mirror neurons allow student readers to experience literature and emotionally put themselves into situations they might not otherwise experience; and therefore, Atticus is worthy of direct character study. Ancillary texts to support Atticus' heroic example are shared, including the films Gandhi, High Noon, and 12 Angry Men as well as the song "I Won't Back Down.†Finally, excerpts from student responses comparing and contrasting characters in the various texts demonstrate a deeper understanding of the fulcrum text (To Kill a Mockingbird) as well as personal thematic connection by students

    Ideal gas behavior of a strongly-coupled complex (dusty) plasma

    Get PDF
    In a laboratory, a two-dimensional complex (dusty) plasma consists of a low-density ionized gas containing a confined suspension of Yukawa-coupled plastic microspheres. For an initial crystal-like form, we report ideal gas behavior in this strongly-coupled system during shock-wave experiments. This evidence supports the use of the ideal gas law as the equation of state for soft crystals such as those formed by dusty plasmas.Comment: 5 pages, 5 figures, 5 authors, published versio

    Informatics for RNA sequencing: A web resource for analysis on the cloud

    Get PDF
    Massively parallel RNA sequencing (RNA-seq) has rapidly become the assay of choice for interrogating RNA transcript abundance and diversity. This article provides a detailed introduction to fundamental RNA-seq molecular biology and informatics concepts. We make available open-access RNA-seq tutorials that cover cloud computing, tool installation, relevant file formats, reference genomes, transcriptome annotations, quality-control strategies, expression, differential expression, and alternative splicing analysis methods. These tutorials and additional training resources are accompanied by complete analysis pipelines and test datasets made available without encumbrance at www.rnaseq.wiki

    Mining our Archives: Reflecting on Artifacts to Improve Writing Instruction

    Get PDF
    By carefully considering our past, we can better adjust our present to improve our future writing and instruction. This article features the reflections of a former high school English teacher and current undergraduate writing methods instructor along with three pre-service English teachers on writing-related artifacts from their personal archives. The co-authors present teaching principles they have developed after reflecting on which writing-related artifacts they’ve kept, why they've kept those artifacts, and what those artifacts suggest about how we should teach writing. Finally, the co-authors encourage both students and teachers to engage in a similar reflective process and productively dialogue with our writing pasts
