Remote Sensing
This dual conception of remote sensing brought us to the idea of preparing two different books; in addition to the first book which displays recent advances in remote sensing applications, this book is devoted to new techniques for data processing, sensors and platforms. We do not intend this book to cover all aspects of remote sensing techniques and platforms, since it would be an impossible task for a single volume. Instead, we have collected a number of high-quality, original and representative contributions in those areas
Towards COP27: The Water-Food-Energy Nexus in a Changing Climate in the Middle East and North Africa
Due to its low adaptability to climate change, the MENA region has become a "hot spot". Water scarcity, extreme heat, drought, and crop failure will worsen as the region becomes more urbanized and industrialized. Both water and food scarcity are made worse by civil wars, terrorism, and political and social unrest. It is unclear how climate change will affect the MENA water–food–energy nexus. All of these concerns need to be empirically evaluated and quantified for a full climate change assessment in the region. Policymakers in the MENA region need to be aware of this interconnection between population growth, rapid urbanization, food safety, climate change, and the global goal of lowering greenhouse gas emissions (as planned in COP27). Researchers from a wide range of disciplines have come together in this SI to investigate the connections between water, food, energy, and climate in the region. By assessing the impacts of climate change on hydrological processes, natural disasters, water supply, energy production and demand, and environmental impacts in the region, this SI will aid in implementation of sustainable solutions to these challenges across multiple spatial scales
JSC Director's Discretionary Fund Program
The JSC Center Director's Discretionary Fund Program 1991 Annual Report provides a brief status of the projects undertaken during the 1991 fiscal year. For this year, four space exploration initiative related issues were focused on: regenerative life support, human spacecraft design, lunar surface habitat, and in situ resource utilization. In this way, a viable program of life sciences, space sciences, and engineering research has been maintained. For additional information on any single project, the individual investigator should be contacted
Joint ACCESS: high-speed assault connector (HSAC) for joint expeditionary logistics
Includes suppmentary materialThe current notion of seabasing requires that three Battalion Landing Teams (BLT) of a
2025 Joint Expeditionary Brigade (JEB) need to be able to transit from the Sea Base to
the objective within a 10 hour period. Of the three BLTs, two of them must be
transported by surface craft a distance of no more than 200nm in sea state 4 or less.
The two surface bound BLTs need to be loaded onto the transporting craft and delivered
to shore, whether it is a port facility or austere beachhead. There is no current or
future system of connectors to meet all the time-distance, sea state, and interface
flexibility requirements for this aspect of seabasing. To meet these requirements a
High Speed Assault Connector (HSAC) is needed which either augments current or replaces
existing connector platforms to deliver and support the required forces ashore. The
Joint ACCESS is a HSAC that brings the necessary speed, payload capacity, interface
capability, and mission flexibility needed to fill the Sea Base to shore transportation
gap. With a maximum speed of 43kts and payload capacity of 800LT, 12 Joint ACCESS
trimarans can transit 200nm and fully offload in 7 hours. Its beachable design uses a
floating bow ramp to reach out to austere beaches, while its combat system suite
provides self defense in addition to robust offensive capabilities.http://web.archive.org/web/20050218202650/http://www.nps.navy.mil/tsse/files/2004.htmApproved for public release; distribution is unlimited
NASA university program management information system, FY 1994
The University Program report, Fiscal Year 1994, provides current information and related statistics for 7841 grants/contracts/cooperative agreements active during the reporting period. NASA field centers and certain Headquarters program offices provide funds for those activities in universities which contribute to the mission needs of that particular NASA element. This annual report is one means of documenting the NASA-university relationship, frequently denoted, collectively, as NASA's University Program

Protection and Spatial Reuse in Optical Burst Transport (OBT) Networks
Abstract — Optical Burst Transport network is a novel WDM ring architecture for Metropolitan Area Networks (MAN). It leverages the advantages of optical burst switching and WDM rings, while using a token-based medium access scheme. In this paper, we investigate protection together with spatial reuse property. Specifically we show how protection in OBT can be different from conventional protection and propose three algorithms for implementing a fast and low implementation cost, unidirectional 1:1 protection scheme. We analyzed the performance of these schemes via simulation and found an optimum algorithm for minimizing data loss and maximizing data delivery during the fault. Index Terms—MAN architecture, optical burst switching, optical burst transport, spatial reuse, WDM rings. M I
