SatMagazine Page 6 July/August 2020 Off-the-shelf routers or switches are designed for constant speed terrestrial links and there is no established standard to provide feedback from variable speed links. Without this information, the links need to include headroom to accommodate lower link speeds during rain fades, which leaves capacity unused most of the time. Alternatively, if the link operates without headroom, there will be too much traffic when the link is impaired, leading to congestion at the satellite modem and resulting in poor user Quality of Experience (QoE) and degraded services. Worse, routing and signaling packets such as BGP could be discarded resulting in routers declaring the route unavailable, flapping or network instability. Interference can be different across multiple carriers leading to even more challenges Many telcos have been able to accommodate the additional demand when the links data rates don’t vary in concert with each other. within their deployed terrestrial infrastructure. In Korea, network loading Increasing the satellite link bandwidth introduces another issue, the is still only 45 to 60 percent of network capacity even with the additional ability to fill such a large pipe.

  • Design and Production of a UM Photo Album
    Design and Production of a UM Photo Album by Daniel Kennedy David Johnson A thesis submitted to the faculty of The University of Mississippi in partial fulfillment of the requirements of the Sally McDonnell Barksdale Honors College. Oxford May 2018 Approved by ___________________________________ Advisor: Dr. Jack McClurg ___________________________________ Reader: Dr. Matt O’Keefe ___________________________________ Reader: Dr. Jeremy Griffin Acknowledgements The authors would like to thank all the CME faculty and staff that made this project possible. Without their commitment to the students and the program, projects like this one would never make if off the ground. The authors would like to extend special thanks to Richard Hairston who served as a technical advisor for the project. Special thanks also the CME professors Dr. Vaughn, Dr. McClurg, and Ms. Watanabe. Their guidance was invaluable when the team found itself deep in the weeds. Lastly the authors would like to thank their amazing team that made this idea come to life. Their hard work made this endeavor successful. ii Abstract The following project attempted to design and manufacture a wooden photo album. The final product needed to fully satisfy customer demands as well as turn a profit. The development proceeded in two phases. The design phase sought to take the product from ideation to a fully viable final design for manufacturing. The manufacturing phase sought to create a production process that would both meet customer demands in an efficient and waste-free way. This would be accomplished by implementing principles of Project Management, Toyota Production System, and LEAN. The final product was successfully designed and produced to be a high-end oak photo album with leather and brass accenting.
