This paper present new evolutionary computations extending toward the lower main sequence previous computations given for globular cluster stars. We discuss the physical inputs with particular regard to the limit of the adopted usual treatment of the stellar atmosphere, which allows a tight correlation with actual stellar structures only for selected range of masses, depending on the assumed me...

In this paper, we propose an intelligent location-aware city guide system which uses a “metal detector” interface for navigating users. Our system allows users to detect shops that match their preferences, in the same way an actual metal detector would be used to find metal objects. The procedure for finding shops that match users’ preferences includes a novel algorithm for learning frequented ...

In the past few years, astronomers have uncovered several very low-temperature, metal-poor stars with halo or thick disk kinematics and peculiar spectral and photometric properties, so-called ultracool subdwarfs. These include the first examples of L subdwarfs metal-poor analogs of the L dwarf spectral class and slightly metal-deficient T dwarfs. Ultracool subdwarfs provide useful empirical tes...

The Electrical Conductivity Object Locator (ECOL) has been developed with the goal of detecting buried objects. Its specific capability to detect and characterize small-size plastic and metal objects buffed at shallow depths is demonstrated. The technique can also detect larger objects at greater depths. The ECOL technique maps the soil subsurface conductivity and identifies variations in the c...

After a brief introduction to Humanitarian Demining we will review the basic principles of the electromagnetic detection of metallic objects, especially induction devices (“metal detectors”), and see how they are applied in Humanitarian Demining and Civil Engineering, with emphasis on visualization techniques. We will then report on tests of a commercial “imaging metal detector” aimed at trying...

Subject was to evaluate techniques for the reduction of metal artifacts in X-ray computed tomographies (CT). Compared to simulated CT projection data, real measurements allowed less improvements in image quality. Neither could metal artifacts be eliminated completely, nor was there a signiicant gain regarding the presentation of anatomical structures in the immediate neighbourhood of metal obje...

Common adhesives stick to a wide range of materials immediately after they are applied to the surfaces. To prevent indiscriminate sticking, smart adhesive materials that adhere to a specific target surface only under particular conditions are desired. Here we report a polymer hydrogel modified with both β-cyclodextrin (βCD) and 2,2'-bipyridyl (bpy) moieties (βCD-bpy gel) as a functional adhesiv...

In this paper we present a structure-preserving dual-energy (SPDE) CT reconstruction method for security, which provides enhanced estimates of material-dependent basis coefficient images. In security applications many different materials may be scanned in various degrees of clutter and metal objects are common. Image noise and metal artifacts are often severe and can lower the accuracy of mater...
