Qualitative life history data were used to explore the experiences of women who live at five fish-landing sites on Lake Victoria, Uganda. We explored what economic and social opportunities women have in order to try to understand why some women are more vulnerable to violence and other risks than others and why some women are able to create successful enterprises while others struggle to make a...

Introduction: Mars is the " horizon goal " for human space flight [1]. Towards that endeavor, one must consider several factors in regards to choosing a landing site suitable for a human-rated mission including: entry, descent, and landing (EDL) characteristics, scientific diversity, and possible insitu resources [2]. Selecting any one place is a careful balance of reducing risks and increasing...

Abstract The Lunar Geophysical Network (LGN) mission is proposed to land on the Moon in 2030 and deploy packages at four locations enable geophysical measurements for 6–10 yr. Returning lunar surface with a long-lived network key next step advance planetary science. LGN will greatly expand our primarily Apollo-based knowledge of deep interior by identifying characterizing mantle melt layers, as...

In this paper we discuss the benefits of using full reinforcement operators for site selection in spacecraft landing on planets. Specifically we discuss a modified Uninorm operator for evaluating sites and a Fimica operator to aggregate pixels for constructing regions that will act as sites to be selected at lower spacecraft altitude. An illustrative case study of spacecraft target landing is p...

Introduction of non-indigenous species into a well-established ecosystem can be detrimental, resulting in both ecological and economical damage. Two specimens of giant mud crab, Scylla serrata were found for the first time in two geographically distinct mud crab landing sites (Matang Mangrove Forest Reserve, Perak and Kota Marudu Mangrove Forest, Sabah) in Malaysia. Their identities were confir...

Flight test results and lessons learned are presented for a helicopter UAV low-altitude navigation and landing system. Results are given for both urban and natural settings. The navigation component uses a quasi-3D A* approach to route planning that enables maneuver through complex terrain using real-time sensor data. The landing component performs landings to sites that it determines to be saf...

Introduction: OMEGA-MEx has targeted the three PHOENIX landing sites during the early 2004 summer (Ls=90°-110°). Amongst the primary goals of these observations, there were to detect water ice exposures, identify the presence of altered minerals such as phyllosilicates and/or sulfates, estimate the surface hydration, and check anomalies in the thermal properties. The results for the three landi...
