Hand Operated Tabletop Letterpress Assembly Instructions 1.0, George Chiu, Brendan Domos, Spencer Herzog, Nathan Sandidge, Kevin Weinstein

Theses

A group of RIT Mechanical Engineering students spent the 2014-2015 academic year in their senior design class collaborating with the RIT Cary Graphic Arts Collection to design and fabricate a 21st century hand-operated platen press.

The press that was designed during this engineering exercise met several requirements:

• be under 30 lbs
• fit in a 24 inch square table top space
• be manufactured with a majority of components which could be purchased from a standard parts supplier
• be able to print with commonly manufactured ink rollers, ink, letterpress chases, spacing and furniture
• the platen and packing had to be adjustable to …

Design And Implementation Of An Interactive Animatronic System For Guest Response Analysis, Brian Burns

GS4 Georgia Southern Student Scholars Symposium

For nearly half a century, animatronic figures have provided entertainment in the theme park industry by simulating life-like animations and sounds. These figures enhance the storytelling experience by stimulating visual and audio senses among guests. Animatronics must be identified as human partners to establish status for dynamic interactions for enhanced acceptance and effectiveness as socially-interactive agents. An animatronic dragon, Kronos, has been designed, fabricated and implemented with human-identification sensors. The primary sensor input comes from an infrared camera, the PrimeSense Carmine, and includes an Arduino Mega 2560 as the center of control. Using the data from the depth camera, people …

Design And Implementation Of An Interactive Animatronic System For Guest Response Analysis, Brian Burns

Electronic Theses and Dissertations

In theme park based entertainment applications, there is a need for interactive, autonomous animatronic systems to create engaging and compelling experiences for the guests. The animatronic figures must identify the guests and recognize their status in dynamic interactions for enhanced acceptance and effectiveness as socially interactive agents, in the general framework of human-robot interactions. The design and implementation of an interactive, autonomous animatronic system in form of a tabletop dragon and the comparisons of guest responses in its passive and interactive modes are presented in this work. The dragon capabilities include a four degrees-of-freedom head, moving wings, tail, jaw, blinking …

Design Of A High Intensity Turbulent Combustion System, Mohammad Arif Hossain

Open Access Theses & Dissertations

In order to design next generation gas turbine combustor and rocket engines, a systematic study of flame structure at high intensity turbulent flow is necessary. The fundamental study of turbulent premixed combustion has been a major research concern for decades. The work is focused on the design and development of a high intensity turbulent combustion system which can be operated at compressible (0.3 < M < 0.5), preheated (T0=500K) and premixed conditions in order to investigate the 'Thickened Flame' regime. An air-methane mixture has been used as the fuel for this study. An optically accessible backward-facing step stabilized combustor has been designed for a maximum operating pressure of 6 bar. A grid has been introduced with different blockage ratios (BR = 54%, 61% & 67%) in order to generate turbulence inside the combustor for the experiment. Optical access is provided via quartz windows on three sides of the combustion chamber. Finite Element Analysis (FEA) is done in order to verify the structural integrity of the combustor at rated conditions. In order to increase the inlet temperature of the air, a heating section was designed to use commercially available in-line heaters. Separate cooling subsystems have been designed for chamber cooling and exhaust cooling. The LabVIEW software interface has been selected as the control mechanism for the experimental setup. A 10 kHz Time Resolved Particle Image Velocimetry (TR-PIV) system and a 3 kHz Planer Laser Induced Fluorescence (PLIF) system have been integrated with the system in order to diagnose the flow field and the flame respectively. The primary understanding of the flow field inside the combustor was achieved through the use of Detached Eddy Simulation (DES) by using commercially available software package ANSYS FLUENT. Preliminary validation is done by 10 kHz TR-PIV technique. Both qualitative and quantitative analysis have been done for CFD and experiment. Major flow parameters such as average velocity, fluctuation of velocity, kinetic energy, and turbulent intensity have been calculated for two distinct Reynolds number (Re = 815 & 3500). PIV results are compared with CFD results which show significant agreement with each other.
