2394-3661, Volume-4, Issue-4, April 2017 JPEG Based Compression Algorithm Mazen Abuzaher, Jamil Al-Azzeh Abstract— Lossy image compression algorithms provide us with very small image size with a slight loss of image quality due to compression.
7-zip Compression Settings Guide Digital Studio 7 This guide is created to help 7-zip users understand what settings do what and how to achieve best compression on their systems, for this guide I am using 7-zip gui however I believe reading this guide will help you with commend line version as well.

Short Notes on Design of Steel Structures Tension Member A tension member in which reversal of direct stress due to loads other then wind or earthquake forces has maximum slenderness ratio =180 A member normally acting as a tie in roof truss or bracing system.
