You need to consider so many factors like the bow string’s craftsmanship, how it will be used, the material, the type of bow string, and so many more. If you don’t get a compound bow string that’s suitable for your strength level and needs, then it might end up hurting you or it might not be effective enough. That’s why we’ve done all the research to help you figure out which is the best bow string for you. So read on for a detailed overview of the best compound bow strings on the market. Best Compound Bow Strings 1. KESHES B-55 Dacron Replacement Recurve Bowstring https://www.amazon.com/dp/B075RVGBSS KESHES B-55 Dacron Bowstring is the latest version of the highly-acclaimed Dacron series. This bowstring is as powerful and has as much stretch as the B-50, but it’s more durable and lasts longer because the stretch is less permanent. -

Santa Fe, New Mexico 2015 Proceedings Simply String Art Carol Beard, Central Michigan University, USA Key Words: String art, surface design Purpose: Simply String Art was inspired by an art piece at the Saint Louis Art Museum. I was intrigued by a painting where the artist had created a three dimensional effect with a string art application over highlighted areas of his painting. I wanted to apply this visual element to the surface of fabric used in apparel construction. The purpose of this piece was to explore string art as unique artistic interpretation for a surface design element. I have long been interested in intricate details that draw the eye and take something seemingly simple to the realm of elegance. Process: The design process began with a research of string art and its many interpretations. -
Radial Weavings
Radial Weavings Mandalas are a form of art that uses radial symmetry and geometric shape. This work, Mandala Cosmic Tapestry in the 9th Roving Moon Up-Close, features complex crocheted patterns, colors, and textures. The artist, Xenobia Bailey is known for their textile works, especially crocheted mandalas. Bailey famously draws inspiration from funk music and Native American, African, Hindu, and Buddhist cultures when creating her work. Experiment with radial symmetry and textile techniques to create a radial weaving. Supplies Needed: Xenobia Bailey (American, born 1955) Mv:#9 (Mandala Cosmic Tapestry in the 9th Roving Moon Up-Close) from • Cardboard or paper plate the series Paradise Under Reconstruction in the Aesthetic of Funk, Phase II, 1999, Crochet, acrylic and cotton yarn, • A circle tracer or compass beads and cowrie shell. Purchase: The Reverend and Mrs. • Yarn, string or fabric scraps Van S. Merle-Smith, Jr. Endowment Fund, 2000. • Scissors (2000.17.2) Follow these steps to make your radial weaving: Step 1: Trace and cut out a cardboard circle. You can also use a paper plate or paper bowl. This will be your loom. Step 2: Use your scissors to make an odd number of cuts into the edge of your loom. They should be evenly spaced out, like slices of pizza. Your cuts should be about an inch long. Step 3: Tie a knot at the end of a long piece of string. Slide it through the back of one of the cuts in your cardboard. Thread your loom by running the long piece of yarn through all of the cuts in the loom. -
Bath Time Travellers Weaving
Bath Time Travellers Weaving Did you know? The Romans used wool, linen, cotton and sometimes silk for their clothing. Before the use of spinning wheels, spinning was carried out using a spindle and a whorl. The spindle or rod usually had a bump on which the whorl was fitted. The majority of the whorls were made of stone, lead or recycled pots. A wisp of prepared wool was twisted around the spindle, which was then spun and allowed to drop. The whorl acts to keep the spindle twisting and the weight stretches the fibres. By doing this, the fibres were extended and twisted into yarn. Weaving was probably invented much later than spinning around 6000 BC in West Asia. By Roman times weaving was usually done on upright looms. None of these have survived but fortunately we have pictures drawn at the time to show us what they looked like. A weaver who stood at a vertical loom could weave cloth of a greater width than was possible sitting down. This was important as a full sized toga could measure as much as 4-5 metres in length and 2.5 metres wide! Once the cloth had been produced it was soaked in decayed urine to remove the grease and make it ready for dying. Dyes came from natural materials. Most dyes came from sources near to where the Romans settled. The colours you wore in Roman times told people about you. If you were rich you could get rarer dyes with brighter colours from overseas.

The Musical Kinetic Shape: a Variable Tension String Instrument
The Musical Kinetic Shape: AVariableTensionStringInstrument Ismet Handˇzi´c, Kyle B. Reed University of South Florida, Department of Mechanical Engineering, Tampa, Florida Abstract In this article we present a novel variable tension string instrument which relies on a kinetic shape to actively alter the tension of a fixed length taut string. We derived a mathematical model that relates the two-dimensional kinetic shape equation to the string’s physical and dynamic parameters. With this model we designed and constructed an automated instrument that is able to play frequencies within predicted and recognizable frequencies. This prototype instrument is also able to play programmed melodies. Keywords: musical instrument, variable tension, kinetic shape, string vibration 1. Introduction It is possible to vary the fundamental natural oscillation frequency of a taut and uniform string by either changing the string’s length, linear density, or tension. Most string musical instruments produce di↵erent tones by either altering string length (fretting) or playing preset and di↵erent string gages and string tensions. Although tension can be used to adjust the frequency of a string, it is typically only used in this way for fine tuning the preset tension needed to generate a specific note frequency. In this article, we present a novel string instrument concept that is able to continuously change the fundamental oscillation frequency of a plucked (or bowed) string by altering string tension in a controlled and predicted Email addresses: [email protected] (Ismet Handˇzi´c), [email protected] (Kyle B.

A Gis Tool to Demonstrate Ancient Harappan
A GIS TOOL TO DEMONSTRATE ANCIENT HARAPPAN CIVILIZATION _______________ A Thesis Presented to the Faculty of San Diego State University _______________ In Partial Fulfillment of the Requirements for the Degree Master of Science in Computer Science _______________ by Kesav Srinath Surapaneni Summer 2011 iii Copyright © 2011 by Kesav Srinath Surapaneni All Rights Reserved iv DEDICATION To my father Vijaya Nageswara rao Surapaneni, my mother Padmaja Surapaneni, and my family and friends who have always given me endless support and love. v ABSTRACT OF THE THESIS A GIS Tool to Demonstrate Ancient Harappan Civilization by Kesav Srinath Surapaneni Master of Science in Computer Science San Diego State University, 2011 The thesis focuses on the Harappan civilization and provides a better way to visualize the corresponding data on the map using the hotlink tool. This tool is made with the help of MOJO (Map Objects Java Objects) provided by ESRI. The MOJO coding to read in the data from CSV file, make a layer out of it, and create a new shape file is done. A suitable special marker symbol is used to show the locations that were found on a base map of India. A dot represents Harappan civilization links from where a user can navigate to corresponding web pages in response to a standard mouse click event. This thesis also discusses topics related to Indus valley civilization like its importance, occupations, society, religion and decline. This approach presents an effective learning tool for students by providing an interactive environment through features such as menus, help, map and tools like zoom in, zoom out, etc. -
