Although the extreme miniaturization of components in integrated circuits and biochemical chips has driven the development of various nanofabrication technologies, the 3D fabrication of nanoscale objects is still in its infancy. Here we propose a novel method to fabricate a free-standing nanowall by the precise, repetitive deposition of electrospun polymer nanofibers. We show that the electrifi...

Automatic identification and localization of cartographic objects in aerial and satellite images have gained increasing attention in recent years in digital photogrammetry and remote sensing. Although the automatic extraction of man made objects in essence is still an unresolved issue, the man made objects can be extracted from aerial photos and satellite images. Recently, the high-resolution s...

Metallicity is a key parameter that controls many aspects in the formation and evolution of stars and galaxies. In this review we focus on the metal deficient galaxies, in particular the most metal-poor ones, because they play a crucial rôle in the cosmic scenery. We first set the stage by discussing the difficult problem of defining a global metallicity and how this quantity can be measured fo...

Material recognition enables robots to incorporate knowledge of material properties into their interactions with everyday objects. For instance, material recognition opens up opportunities for clearer communication with a robot, such as “bring me the metal coffee mug”, and having the ability to recognize plastic versus metal is crucial when using a microwave or oven. However, collecting labeled...

• a short biography of John Doe. – born on April 3rd, 1975 in Smallville. His birth was registered on April 4th, 1975. – He went to live on his own in Bigtown. Although he moved out on August 26th, 1994, he forgot to register the change of address officially. – He updated his record on December 27, 1994. – John Doe was accidentally hit by a truck on April 1st, 2001. The coroner reported his dat...

Language engineers often point to tight connections between their systems’ linguistic representations and accumulated sensor data as a sign that their systems really mean what they say. While we believe such connections are an important piece in the puzzle of meaning, we argue that perceptual grounding alone does not suffice to explain the specific, stable meanings human speakers attribute to e...

In this paper, we present a general approach to shape characterization and deformation analysis of 2D/3D deformable visual objects. In particular, we define a reference dynamic model, encoding morphological and functional properties of an objects class, capable to analyze different scenarios in heart left ventricle analysis. The proposed approach is suitable for generalization to the analysis o...

Turtles can be unintentionally hooked during recreational and commercial fishing operations. While hook ingestion is not always fatal, ingested hooks harm or kill turtles by damaging soft tissues affecting digestion. Detecting other metallic debris in the field a challenge. As such, we tested efficacy of handheld metal detector detecting fish incidental freshwater Georgia, USA. We captured 426 ...
