    Bricklayer: An Authentic Introduction to the Functional Programming Language SML

    Full text link
    Functional programming languages are seen by many as instrumental to effectively utilizing the computational power of multi-core platforms. As a result, there is growing interest to introduce functional programming and functional thinking as early as possible within the computer science curriculum. Bricklayer is an API, written in SML, that provides a set of abstractions for creating LEGO artifacts which can be viewed using LEGO Digital Designer. The goal of Bricklayer is to create a problem space (i.e., a set of LEGO artifacts) that is accessible and engaging to programmers (especially novice programmers) while providing an authentic introduction to the functional programming language SML.Comment: In Proceedings TFPIE 2014, arXiv:1412.473

    A Note on Solid Coloring of Pure Simplicial Complexes

    We establish a simple generalization of a known result in the plane. The simplices in any pure simplicial complex in R^d may be colored with d+1 colors so that no two simplices that share a (d-1)-facet have the same color. In R^2 this says that any planar map all of whose faces are triangles may be 3-colored, and in R^3 it says that tetrahedra in a collection may be "solid 4-colored" so that no two glued face-to-face receive the same color.Comment: 11 pages, 6 figure

    The Relationship between Human Beings and Nature

    Get PDF
    The symbolic value of art helps me as a metal artist to depict the relation between human beings and nature. Humans have created a culture and a world but this world appears to coldly separate itself from its surroundings. Life continues to assert its will on human creation; plants sprout amongst concrete and steel environments. The composite shape of my sculptures and thesis help me to present a contemporary perspective on this issue

    “Design, Development and Characterization of a Thermal Sensor Brick System for Modular Robotics

    This thesis presents the work on thermal imaging sensor brick (TISB) system for modular robotics. The research demonstrates the design, development and characterization of the TISB system. The TISB system is based on the design philosophy of sensor bricks for modular robotics. In under vehicle surveillance for threat detection, which is a target application of this work we have demonstrated the advantages of the TISB system over purely vision-based systems. We have highlighted the advantages of the TISB system as an illumination invariant threat detection system for detecting hidden threat objects in the undercarriage of a car. We have compared the TISB system to the vision sensor brick system and the mirror on a stick. We have also illustrated the operational capability of the system on the SafeBot under vehicle robot to acquire and transmit the data wirelessly. The early designs of the TISB system, the evolution of the designs and the uniformity achieved while maintaining the modularity in building the different sensor bricks; the visual, the thermal and the range sensor brick is presented as part of this work. Each of these sensor brick systems designed and implemented at the Imaging Robotics and Intelligent Systems (IRIS) laboratory consist of four major blocks: Sensing and Image Acquisition Block, Pre-Processing and Fusion Block, Communication Block, and Power Block. The Sensing and Image Acquisition Block is to capture images or acquire data. The Pre-Processing and Fusion Block is to work on the acquired images or data. The Communication Block is for transferring data between the sensor brick and the remote host computer. The Power Block is to maintain power supply to the entire brick. The modular sensor bricks are self-sufficient plug and play systems. The SafeBot under vehicle robot designed and implemented at the IRIS laboratory has two tracked platforms one on each side with a payload bay area in the middle. Each of these tracked platforms is a mobility brick based on the same design philosophy as the modular sensor bricks. The robot can carry one brick at a time or even multiple bricks at the same time. The contributions of this thesis are: (1) designing and developing the hardware implementation of the TISB system, (2) designing and developing the software for the TISB system, and (3) characterizing the TISB system, where this characterization of the system is the major contribution of this thesis. The analysis of the thermal sensor brick system provides the user and future designers with sufficient information on parameters to be considered to make the right choice for future modifications, the kind of applications the TISB could handle and the load that the different blocks of the TISB system could manage. Under vehicle surveillance for threat detection, perimeter / area surveillance, scouting, and improvised explosive device (IED) detection using a car-mounted system are some of the applications that have been identified for this system

    Graphic Designers and Brain Surgeons, Both Highly Trained, Yet Not Interchangeable: The Creation of Promotion Materials for Springfest 2014

    Graphic design and brain surgery. What do they have in common? Each person is trained in their profession. Each person is called upon for services that are needed for a specific reason. Common sense tells you to not perform brain surgery without the proper training. Why would that be any different for Graphic Design? Whereas most people would never attempt brain surgery, the average person seems more than willing to attempt creating Graphic Design, usually with poor results. Event branding is an example of where training in this profession is most beneficial. I was the Graphic Designer in charge of creating the branding needs for the week-long 2014 “Springfest” event for my clients, Matt Miller and Gianna Mazzola from the University’s student-run Program Committee. This required the creation of cohesive product design, frequent communication with the client, and a balance between client specifications and personal creative input. The goal was to design a fully realized brand system that would captivate the consumer and evoke the appropriate feel of the 2014 Springfest theme: Lego©

    Heritage and Cultural Heritage objects loaded with historical and cultural content have a high level of significance to be preserved. This position is reinforced by the resence of a set of legislation that is highly relevant to this need. The parent is the Law of the Republic of Indonesia Number 5 of 1992 on Heritage Objects. Mentioned in the reamble of the Act that the Heritage Preserve is important to be preserved is for the sake of maintaining local identity. For the city of Yogyakarta, it is clear that the Objects of Cultural Heritage and Heritage which became one of the forerunner of ancestral cultures, is a form of identity and a source of pride for the community that should not be eliminated. Heritage and Cultural Heritage objects need to be preserved, not just social cultural life, but also all artifacts, ’petilasan’s and objects that are left with the life of the past. Understanding of Architectural Research and some matters relating to Heritage and Cultural Heritage by architectural style need to be understood. In this research research, limited to Pattern and Style of Architecture in Indie Period which during the past period grow and develop as Heritage and Cultural Heritage objects in Yogyakarta City. Bintaran area becomes a sample of this research activity because of the development of style and pattern of Architecture of Building

    Joining Constraint Satisfaction Problems and Configurable CAD Product Models: A Step-by-Step Implementation Guide

    Get PDF
    In configuration design, the task is to compose a system out of a set of predefined, modu-lar building blocks assembled by defined interfaces. Product configuration systems, both with or without integration of geometric models, implement reasoning techniques to model and explore the resulting solution spaces. Among others, the formulation of constraint satisfaction problems (CSP) is state of the art and the informational background in many proprietary configuration engine software packages. Basically, configuration design tasks can also be implemented in modern computer aided design (CAD) systems as these contain different techniques for knowledge-based product modeling but literature reports only little about detailed application examples, best practices or training materials. This article aims at bridging this gap and presents a step-by-step implementation guide for CSP-based CAD configurators for combinatorial designs with the example of Autodesk Inventor

    Field Excavation Report Season 1: 2018 Summer Field School Millard’s Farmstead 41NA416 Permit #8424

    Get PDF
    In the summer of 2018 (June 4-July6), SFA Archaeological Field School (ANT440) was lead by Dr. Leslie G. Cecil and Laura Short (adjunct professor at the time) and had 10 students and one volunteer. The site selected was the Millard’s Farmstead located behind the Nacogdoches ISD Agricultural Center on the Northwest Loop in Nacogdoches, TX. The site is approximately 1.62 acres in area of which only 28 m2 were excavated. Alton Frailey (the NISD superintendent at the time) approved the excavation of the site for multiple field seasons. The site currently sits on NISD property. A pedestrian survey in April 2018 located the farmstead’s fireplace and excavations were conducted around it to best determine the placement of the house. The house had been razed during the 1970s; however, the crib barn still stood. At the end of the field season, representatives moved the crib barn to Millard’s Crossing under George Avery’s supervisions. A total of 9026 artifacts were recovered and are curated at the SFA Anthropology and Archaeology Laboratory. Future research at the site will continue once COVID-19 is no longer an issue in order to capture other information about this time period in Nacogdoches history

    THE EVALUATION OF THE ART OF PERSIAN PAINTING (FROM THE BEGINNING TO THE ADVENT OF ISLAM)

    Get PDF
    Abstract. Painting is the manifestation of expression, yearning heart, attitude and worldview represents of aterritory people; hence it is an important element in the study of beliefs and the gradual perfection of their spirit. The history of painting in Iran can be found in the remains of Paleolithic period and images of caves in Lorestan - Mirmelas and Dushh; although Will Durant believes that the start of this art is from the time of painting on the pottery. Iranian paintings regardless of the period in which the image is drawn, reflect special idealism. Iranian painter would not represent the exact nature; he devotes all his time to emphasize the beauty of painting. Painting in pre- Islam whether those drawn in old books and manuscripts or on the walls and little scales always have maintained their relation between poem, culture, local beliefs, legends and myths. And this feature distinguishes Iranian paintings. Arjang is a perfect example of the evolution of these relations.Key words: painter, art of painting, Iran, prehistory, ancient Iran
