We describe a prototype software system for investigating novel human-computer interaction techniques for 3-D geospatial data. This system, M4-Geo (Multi-Modal Mesh Manipulation of Geospatial data), aims to provide a more intuitive interface for directly manipulating 3-D surface data, such as digital terrain models (DTM). The M4-Geo system takes place(More)
In this paper, we report our ongoing research into multi-sensory investigation of geo-scientific data. Our Geoscientific Data Investigation System (GDIS) integrates three-dimensional, interactive computer graphics, touch (haptics) and real-time sonification into a multi-sensory Virtual Environment. GDIS has been used to investigate geological structures(More)
systems to interactively manipulate geo-scientific data. These systems could facilitate many complex tasks that geosci-entists in academia and industry face today, lead to new insights, and solve problems in less time. This research applies to many different geoscience branches, but here I focus on the oil and gas industry because I spent the last five(More)
In this paper, we report on our ongoing research into multimodal investigation of geoscientific data. Our system integrates three-dimensional, interactive computer graphics, touch (haptics) and real-time sound synthesis into a multimodal interface. We present applications of multimodal investigations of geoscientific data that pertain to surface meshes on(More)
Experimental and theoretical investigations of the oxidation reaction of CO to form carbon dioxide, catalyzed by size-selected Pd 30 clusters soft-landed on MgO(100), are described. The consequences of pretreatment of the deposited clusters with molecular oxygen, 16 O 2 , at a temperature of ∼370 K followed by annealing at around 450 K are explored.(More)
Combining temperature-programmed reaction measurements, isotopic labeling experiments, and first-principles spin density functional theory, the dependence of the reaction temperature of catalyzed carbon monoxide oxidation on the oxidation state of Pd(13) clusters deposited on MgO surfaces grown on Mo(100) is explored. It is shown that molecular oxygen(More)
