Time-of-flight three-dimensional imaging is an important tool for applications such as object recognition and remote sensing. Conventional time-of-flight three-dimensional imaging systems frequently use a raster scanned laser to measure the range of each pixel in the scene sequentially. Here we show a modified time-of-flight three-dimensional imaging system, which can use compressed sensing tec...

These pages originate as a follow up to the course Conservation Laws delivered by the author at the University of Warsaw in the week 12-16.05.2014. Clearly, not all the theory of Conservation Laws is considered, several subjects are only superficially covered, while others are entirely omitted and the space devoted to the various research directions is not related to their relevance. Unfortunat...

In this contribution, the design, collection, annotation and planned distribution of a new spoken language resource of Afrikaans (SALAR) is discussed. The corpus contains speech of mother tongue speakers of Afrikaans, and is intended to become a primary national language resource for phonetic research and research on pronunciation variations. As such, the corpus is designed to expose pronunciat...

R ecently there’s been a push among some of our clients to start bringing 3d imaging systems in-house. In the majority of cases the client wants my company to provide some form of training to help them get off on the right foot. Although we are in the consulting business, training is a different animal. We’ve worked for years, continuously refining our processes and tools, investing in R&D and ...

We give several remarks on Strichartz estimates for homogeneous wave equation with special attention to the cases of Lx estimates, radial solutions and initial data from the inhomogeneous Sobolev spaces. In particular, we give the failure of the endpoint estimate L 4 n−1 t Lx for n = 2, 3 even for data in inhomogeneous Sobolev spaces.

Lensless ghost imaging (LGI) with thermal light requires an equal length between the test and reference arms. When this condition is not met, the image becomes blurred. Here we propose an experimental scheme of LGI where the lengths of the two arms are not equal. Our experiment shows that when a glass rod is inserted into a longer arm, the clear image can be formed in the intensity correlation ...

Path-sensitive data flow analysis pairs classical data flow analysis with an analysis of feasibility of paths to improve precision. In this paper we propose a framework for path-sensitive backward data flow analysis that is enhanced with an abstraction of the predicate domain. The abstraction is based on a three-valued logic. It follows the strategy that path predicates are simplified if possib...

This Article argues that marriage is an economically efficient institution, designed and evolved to regulate incentive problems that arise between a man and a woman over the life cycle of procreation. As such, its social and legal characteristics will provide a poor match for the incentive problems that arise in the two distinctly different relationships of gay and lesbian couples. Forcing all ...

We discuss the polarized proton-positron scattering in the context of the excess of high-Q 2 events at HERA. We define and estimate a polarized asymmetry to examine the two scenarios, the contact interaction and stop scenario without R-parity. This asymmetry shows a characteristic behavior depending on the scenarios. Thus the polarized experiment at HERA will provide with a good test for these ...
