Lori Coombs, Participant
No full textLori D. Coombs supports NASA’s cybersecurity efforts as the Principal Technical Manager, coordinating the tasks of Engineering teams for Earthdata Infrastructure and Earthdata Login. Lori has experience moving data infrastructures into the Cloud through onboarding initiatives with the Next Generation Application Platform (NGAP) Operations team. NGAP provides a cloud-based Platform-as-a-Service (PaaS) and Infrastructure-as-a-Service (IaaS) solution for Customer applications.
In addition to supporting NASA, throughout her career, she gained experience supporting the Office of Director of National Intelligence (ODNI), (DNI) - Open-Source Center, National Geospatial-Intelligence Agency (NGA), Defense Intelligence Agency (DIA), Architect of the Capitol (AOC) and U.S. Senate where architect and management roles led to supporting the research and development of aviation and geospatial cybersecurity. Lori ensures that all R&D work results in protected technologies for DOD stakeholders. She also serves as an Associate Professor at the University of Arizona Global Campus (UAGC), supporting information systems, environmental science, and advanced air mobility disciplines that address the cross-cutting integration of security and infrastructures across the airspace ecosystem. She is also an Advisor for the Women in Leadership program at Richmond University. Lori is CEO of WWCM and Director of WWCM Academy, a not-for-profit that advocates for students to pursue careers in STEaM.
For over twenty years, Mrs. Coombs has worked on Capitol Hill and continues to be a state-of-the-art leader on and in mission-critical Command, Control, Communications, Computers, Cyber-Defense, and Combative Systems, Intelligence, Surveillance and Reconnaissance (C6ISR) programs.
Lori is currently pursuing a D.Sc. in Cybersecurity at Marymount University. She earned an MS in Systems Engineering from George Washington University, an MBA, and a BS in Business Administration. Lori holds a certification in The Recreational Unmanned Aircraft Systems (UAS) Safety Test (TRUST) / (FAA) for the safety and risk management of unmanned aircraft systems. Lori has publications with EJEL.https://commons.erau.edu/avcysecworkshop-bios-2024/1011/thumbnail.jp
Introducing Microcells into Macrocellular Networks: A Case Study
No full textAbstract?The performance in terms of signal-to-interference ratio (SIR), teletraffic, and spectral efficiency of a combined macrocellular and microcellular network is investigated when either both types of cells share the same channel set, or when the channel set is partitioned between the macrocells and the microcells. The analysis is for time-division multiple access (TDMA) with frequency hopping, power control, and discontinuous transmission, and the radio channel is composed of an inverse fourth-power path loss law with log-normal fading. We commence by introducing a single microcell into a hexagonal cluster of macrocells before considering clustered microcells. Both omni-directional and sectorized cells are examined. We find that high reuse factors are required when channel sharing is employed. When channel partitioning is used, no co-channel interference occurs between the microcells and the macrocells allowing them to be planned independently. The reuse factors in the microcells and macrocells therefore do not need to be increased beyond conventional values. The outcome is that by opting for channel partitioning, the improvement in spectral efficiency compared to channel sharing is two to three times greater. Index Terms?Co-channel interference, land mobile radio cel-lular systems, time division multiaccess
