Model-based Optimization of Compressive Antennas for High-Sensing-Capacity Applications

This paper presents a novel, model-based compressive antenna design method for high sensing capacity imaging applications. Given a set of design constraints, the method maximizes the sensing capacity of the compressive antenna by varying the constitutive properties of scatterers distributed along the antenna. Preliminary 2D design results demonstrate the new method's ability to produce antenna configurations with enhanced imaging capabilities

More on microstate geometries of 4d black holes

We construct explicit examples of microstate geometries of four-dimensional black holes that lift to smooth horizon-free geometries in five dimensions. Solutions consist of half-BPS D-brane atoms distributed in $\mathbb{R}^3$. Charges and positions of the D-brane centers are constrained by the bubble equations and boundary conditions ensuring the regularity of the metric and the match with the black hole geometry. In the case of three centers, we find that the moduli spaces of solutions includes disjoint one-dimensional components of (generically) finite volume.Comment: 25 page

Examining the impact of community factors on student truancy

Truancy has been an ongoing issue in the lives of many urban and low-income students. Poor school attendance has been one of the earliest indicators of academic failure, delinquency, crime, poverty and etc. Although there have been a number of different definitions for truancy, the law has consistently stated that underage students must attend school. It has been clear that addressing and combating truancy has been an issue in many cities. Research has identified many truancy risk indicators and various community factors have appeared to impact truancy rates. Additionally, within an urban setting, the availability of public transportation to and from school has also been implicated as a factor in school attendance. This current study examined the relationship between student truancy rates and community factors and the availability of student transportation. The results found that high school students had higher absent rates, that community factors were not related to number of absences, and a significant interaction between transportation and high school students

Entropy-expansiveness for partially hyperbolic diffeomorphisms

We show that diffeomorphisms with a dominated splitting of the form $E^s\oplus E^c\oplus E^u$, where $E^c$ is a nonhyperbolic central bundle that splits in a dominated way into 1-dimensional subbundles, are entropy-expansive. In particular, they have a principal symbolic extension and equilibrium states.Comment: 15 pages, 1 figur

Real-time audio interaction in serious games for music learning

In this LBD, we present several Apps for playing while learning music or for learning music while playing. The core of all the games is based on the good performance of the real-time audio interaction algorithms developed by the ATIC group at Universidad de Ma ́laga (SPAIN).Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech. This work has been funded by the Ministerio de Econom ıa y Competitividad of the Spanish Government under Project No. TIN2013-47276-C6-2-R and by the Junta de Andalucía under Project No. P11-TIC-7154

A first-principles study and some applied researches of high-temperature superconductors and other low-dimensional functional materials

This thesis comprises two parts: The first is a fundamental theoretical study of hightemperature superconductors (HTS), addressing the energy balances involved in the superconducting pairing (research started under supervision of Prof. A.J. Leggett, in stays at the University of Illinois at Urbana-Champaign, USA). The study presents an extension, to the case of HTS, of equations originally derived for simple superconductors by G.V. Chester that link the energy saved by the superconductivity with the structural properties of the materials. The second part addresses applied aspects of various micro and nanostructured functional materials, including both HTS (optimization of superconducting devices, as bolometric radiation sensors, hybrid piezoelectric-superconducting films, and other) and electrostatic nanostructured microporous (ENM) media for nanofluid filtration
