We present our ongoing design of Snakey, a tangible user interface (TUI) dedicated to the field of reservoir geosciences and engineering. Our design of Snakey emphasizes intuitive manipulation and interaction with 3D curves, common to underground well path exploration and planning. Snakey is not designed to replace the traditional CAD reservoir well path planning tools, but rather to augment th...

The building of complex systems from basic logic gates is one of the hallmarks of circuit design in electrical engineering. The question arises whether a similar strategy can be adopted for the design of artificial biological systems. In this paper, we present the design of two logic gates, a biological ANDand a biological XOR. They can be combined to produce a half-adder, one of the fundamenta...

retrofit of heat exchanger networks for energy saving and/or debottlenecking is one of important aspects of process engineering. pinch technology, as the most efficient tool for the analysis of these networks, has been applied to hundreds of such projects and shown satisfactory results. however, all the existing methods for debottlenecking, using pinch technology, are either based on assumed he...

In Japan new lunar or planetary exploration missions including landers and rovers are earnestly under study. Those missions will follow up SELENE (SELenoligical Engineering Explorer), a lunar global remote sensing mission. One of main missions for lunar robotics exploration in post SELENE missions is to demonstrate the technologies for lunar or planetary surface exploration and human activities...

slope stability analysis is a geotechnical engineering problem characterized by many sources ofuncertainty. in slope stability computations, some of these sources are encountered, such as geologicaldetails missed in the exploration program, estimation of soil properties that are difficult to quantifyand many other relevant factors. therefore, accurate reproduction of the spatial variability in ...
