Technology Refresh of NOAA’s Tropical Atmosphere Ocean (TAO) Buoy System
2016Co-Authors: Chung-chu Teng, Ry J. Bernard, Pete A. LessingAbstract:(NOAA) Tropical Atmosphere Ocean (TAO) buoy array has a long history of providing valuable climate data to both the climate and forecast communities. A major concern for a sustained and long-term TAO operation is the impending obsolescence of the Technology used in the current version of the TAO array. An increasing number of components are being discontinued or are no longer supported by the manufacturers due to the Technology presently used being more than 10 years old. During the transition of the TAO array from NOAA’s Pacific Marine Environmental Laboratory (PMEL) to NOAA’s National Data Buoy Center (NDBC), it was decided to take this opportunity to “Refresh ” the TAO buoy system by replacing the obsolescent components in the current TAO system to ensure continuity of the TAO array. This paper first discusses the obsolescent components in the existing TAO array system. Then, the Refreshed components of the Refreshed TAO buoy system are discussed, including a newly-designed data logger, modified battery system, commercial off-the-shelf underwater sensors, a new compass, Iridium communication, modified and enhanced shore-side data system, and other minor design modifications. The field testing of the TAO Refreshed buoys is also presented. I

optimal Technology Refresh strategies for strategic dmsms management using ranking and selection
Winter Simulation Conference, 2019Co-Authors: James K Starling, Youngjun Choe, Christina M MastrangeloAbstract:The effects of Diminishing Manufacturing Sources and Material Shortages (DMSMS) can be excessively costly if not addressed in a timely manner. A strategic DMSMS management method that seeks to minimize the overall life-cycle cost of a system, e.g. an aircraft or ship, is presented. The goal is to select an optimal scheduling of Technology Refreshes over a fixed lifetime, using lifetime buys as the mitigation option. A DMSMS specific cost model is constructed that accounts for costs of multiple, diverse parts in a system and multiple Technology Refreshes. This study shows the efficacy of using a ranking and selection method to identify the optimal Technology Refresh strategy for a complex and stochastic cost function dependent upon varying Refresh costs. A visual model is presented which provides the ability to quickly compare other feasible strategies.

continuous testing for enterprise portal Technology Refresh
International Conference on Software Engineering, 2007Co-Authors: Mingu Lee, Greg ForemanAbstract:This paper presents experiences and lessons learned detailing software testing for a Technology Refresh project that took place over a period of one year. The paper describes the continuous testing performed while the team ported a web portal from one environment to another, which will probably affect more websites and web portals as time goes on. The original portlet-based application was constructed four years ago and has been experiencing problems during peak demand times. The overall goal of this Technology Refresh project is to achieve stability of the portal-based on a more robust architecture. This paper summarizes test plans and results for iterative functional, automated regression, and continuous performance testing. The team designed the system for better performance, monitored test results from the early stage of the lifecycle, and unveiled potential issues using continuous integration and testing.
