Solvability of the Dirichlet, Neumann and the regularity problems for parabolic equations with H\"older continuous coefficients

We establish the $L^2$-solvability of Dirichlet, Neumann and regularity problems for divergence-form heat (or diffusion) equations with H\"older-continuous diffusion coefficients, on bounded Lipschitz domains in $\mathbb{R}^n$. This is achieved through the demonstration of invertibility of the relevant layer-potentials which is in turn based on Fredholm theory and a new systematic approach which yields suitable parabolic Rellich-type estimates

Transference of local to global L2L^2 maximal estimates for dispersive partial differential equations

In this paper we give an elementary proof for transference of local to global maximal estimates for dispersive PDEs. This is done by transferring local $L^2$ estimates for certain oscillatory integrals with rough phase functions, to the corresponding global estimates. The elementary feature of our approach is that it entirely avoids the use of the wave packet techniques which are quite common in this context, and instead is based on scalings and classical oscillatory integral estimates.Comment: 10 page

VHDL-AMS modeling of self-organizing neural systems

This paper presents VHDL-AMS models and simulation results for a complex, self-organizing neural system based on the adaptive resonance theory. Such neural systems exhibit both discrete and continuous dynamic behavior and consist of a large number of analog equations, a digital controller with analog and digital feedback paths resulting in the complexity that would prohibit analysis with conventional mixed-signal simulation tools

Crecimiento económico e inflación: el caso de México

The analysis focuses on the short-run dynamics of several macroeconomic variables and their relationship with the rate of inflation. The cyclical components of the variables are obtained through the Hodrick- Prescott filter. Contemporaneous correlations between the cyclical components show that inflation rates above their long-term trend are associated with below trend economic activity, employment, investment and real wages and with nominal and real interest rates above their trend. Non-contemporaneous correlations show that inflation has an adverse effect on the referred variables. Results are confirmed through “impulse-response” functions.

La Horqueta Shear Zone, Sierra de Velasco, NW Argentina: petrography, geochemistry, structures and tectonic significance

La Faja de Deformación La Horqueta (FDLH) es la sexta faja de cizalla reconocida en la sierra de Velasco, Sierras Pampeanas, NO de Argentina. Esta faja separa dos tipos de metagranitoides de características petrográficas y geoquímicas contrastadas: metagranodioritas, hacia el SO, consisten en granodioritas con biotita-allanita-titanita débilmente peraluminosas que se asemejan a los granitoides tipo I del sur de la sierra de Velasco y de sierras aledañas pertenecientes al arco magmático famatiniano, mientras que los metagranitos, hacia el NE, consisten en monzogranitos con biotita-muscovita fuertemente peraluminosos idénticos al Ortogneis Antinaco del norte de la sierra de Velasco, el cual pertenece a un cinturón de granitoides tipo S interno, respecto del arco famatiniano. La FDLH, desarrollada a partir de estos dos protolitos, tiene un espesor de 1 a 2 km y está compuesta por protomilonitas y milonitas que desarrollan una fuerte foliación milonítica de rumbo NNO y fuerte inclinación al E. El análisis cinemático indicaría un régimen deformacional transpresivo principal con componente inverso-sinestral, acompañado por una componente de transcurrencia destral N-S subordinada, que habría puesto en contacto ambos ambientes geotectónicos.The La Horqueta Shear Zone (LHSZ) is the sixth shear zone recognized in the Sierra de Velasco, Sie- rras Pampeanas, NW Argentina. This shear zone separates two types of metagranitoids of contrasting petrographical and geochemical characteristics: metagranodiorites, outcropping towards the SW, consist in weakly peraluminous biotite-allanite-titanite granodiorites similar to the I-type granitoids of southern Sierra de Velasco and of neighboring ranges that are part of the Famatinian magmatic arc, while metagranites, outcropping towards the NE, consist of strongly peraluminous biotite-muscovite monzogranites identical to the Antinaco Orthogneis of northern Sierra de Velasco, which is part of an inner S-type granitoid belt. The LHSZ, developed from these two protoliths, has a thickness of 1 to 2 km and is composed of protomyloni- tes and mylonites with strong NNW trending and E dipping mylonitic foliation. Cinematic analysis indicates a main transpressive deformational regime with an inverse-sinistral component, accompanied by a subordi- nate dextral transcurrent component, which possibly placed the two tectonic settings in contact.Fil: López, J.

A Decision Tree and S-Transform Based Approach for Power Quality Disturbances Classification

In this paper, it is presented an automated classification based on S-transform as feature extraction tool and Decision Tree as algorithm classifier. The signals generated according to mathematical models, including complex disturbances, have been used to design and test this approach, where noise is added to the signals from 40dB to 20dB. Finally, several disturbances, simple and complex, have been considered to test the implemented system. Evaluation results verifying the accuracy of the proposed method are presented.IEE

AER Neuro-Inspired interface to Anthropomorphic Robotic Hand

Address-Event-Representation (AER) is a communication protocol for transferring asynchronous events between VLSI chips, originally developed for neuro-inspired processing systems (for example, image processing). Such systems may consist of a complicated hierarchical structure with many chips that transmit data among them in real time, while performing some processing (for example, convolutions). The information transmitted is a sequence of spikes coded using high speed digital buses. These multi-layer and multi-chip AER systems perform actually not only image processing, but also audio processing, filtering, learning, locomotion, etc. This paper present an AER interface for controlling an anthropomorphic robotic hand with a neuro-inspired system.Unión Europea IST-2001-34124 (CAVIAR)Ministerio de Ciencia y Tecnología TIC-2003-08164-C03-02Ministerio de Ciencia y Tecnología TIC2000-0406-P4- 0

Blockverse: A Cloud Blockchain-based Platform for Tracking in Affiliate Systems

Affiliate systems are a crucial piece of today’s online advertising. In affiliate systems, web traffic is directed from certain sites displaying ads to the websites of those company whose products or services are advertised. The way in which these ads are monetized is diverse and can respond to different models. In many cases, affiliates establish a cost based on impressions (displays of the ad) or on clicks. However, more intricate models are becoming widespread, such as the cost per action, where the affiliate incomes are due to the users performing certain actions in the target website. In particular, in the world of iGaming, it is frequent that affiliates charges are based on registrations, deposits or money lost on bets. In this scenario, Blockverse is a tool whose objective is to record transactions occurring in affiliate systems at large scale, using a permissioned blockchain implemented atop state-of-the-art cloud technology. Additionally, the system will be able to execute smart deals that generate income for affiliates based on the agreed conditions, and to provide real-time analytics in the context of the affiliate system
