Until recently, reconstruction algorithms for solving inverse electromagnetic scattering problems have been based on either nonlinear optimization techniques or on linearized models based on weak scattering approximations [6]. In the past ten years a third approach to reconstruction has been developed which comes under the rubric of qualitative methods in inverse scattering theory, the most pop...

• 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...

We review the status of the weak cosmic censorship conjecture, which asserts, in essence, that all singularities of gravitational collapse are hidden within black holes. Although little progress has been made toward a general proof (or disproof) of this conjecture, there has been some notable recent progress in the study of some examples and special cases related to the conjecture. These result...

We propose the implementation of a distributed system for DL storage and retrieval which relies on two earlier developed technologies: buckets and document linking based on user retrieval patterns. Buckets are expanded with a mechanism to keep track of weighted bucket relations. Each bucket keeps track of its connections to other related buckets. A mechanism is put in place which allows buckets...

Low–level vision approaches, such as local image features, are an important component of bottom–up machine vision solutions. They are able to effectively identify local visual similarities between fragments of underlying physical objects. Such vision approaches are used to build a learning system capable to form meaningful visual objects out of unlabelled collections of images. By capturing sim...

A large literature shows that language influences cognition. Yet, we know very little about when and how linguistic influences on cognition become important in development. Here we test the proposal that one pathway by which language affects cognition is by activating category information which influences visual processing, and that this influence starts early. Across two experiments, we show t...
