Enhancement and Edge-Preserving Denoising: An OpenCL-Based Approach for Remote Sensing Imagery

Image enhancement and edge-preserving denoising are relevant steps before classification or other postprocessing techniques for remote sensing images. However, multisensor array systems are able to simultaneously capture several low-resolution images from the same area on different wavelengths, forming a high spatial/spectral resolution image and raising a series of new challenges. In this paper, an open computing language based parallel implementation approach is presented for near real-time enhancement based on Bayesian maximum entropy (BME), as well as an edge-preserving denoising algorithm for remote sensing imagery, which uses the local linear Stein’s unbiased risk estimate (LLSURE). BME was selected for its results on synthetic aperture radar image enhancement, whereas LLSURE has shown better noise removal properties than other commonly used methods. Within this context, image processing methods are algorithmically adapted via parallel computing techniques and efficiently implemented using CPUs and commodity graphics processing units (GPUs). Experimental results demonstrate the reduction of computational load of real-world image processing for near real-time GPU adapted implementation.ITESO, A.C

Achieving rotorcraft noise and emissions reduction for 'Clean Sky' - The measurement of success

This paper describes the work done and strong interaction between Cranfield University as member of the Technology Evaluator (TE) team , Green Rotorcraft (GRC) Integrated Technology Demonstrator (ITD) and Sustainable and Green Engine (SAGE) ITD of the Clean Sky Joint Technology Initiative (JTI). The aim of Clean Sky is to develop and integrate new and innovative technologies that will hel p meeting the emission and noise reduction targets set by the Advisory Council for Aviation Research and Innovation in Europe (ACARE) for aircraft of next generation. The GRC and SAGE ITDs are responsible for developing new helicopter airframe and engine t echnologies respectively, whilst the TE has the distinctive role of assessing the environmental impact of these technologies at single flight (mission), airport and Air Transport System levels (ATS). Cranfield University as a member of the TE is responsibl e for the mission trajectory definition and for conducting the environmental performance assessments . The assessments reported herein have been performed by using a GRC - developed multi - disciplinary simulation framework called PhoeniX (Platform Hosting Oper ational and Environmental Investigations for Rotorcraft) that comprises various computational modules. These modules include a rotorcraft performance code (EUROPA), an engine performance and emissions simulation tool (GSP) and a noise prediction code (HELE NA). PhoeniX can predict the performance of a helicopter along a prescribed 4D trajectory offering a complete helicopter mission analysis. In the context of the TE assessments reported herein, three helicopter classes are examined, namely a Twin Engine Lig ht (TEL) configuration, for Emergency Medical Service (EMS) and Police missions, and a Single Engine Light (SEL) configuration for Passenger/Transport missions, and a Twin Engine Heavy (TEH) configuration for Oil & Gas missions. The different technologies assessed reflect three simulation points which are the ‘Baseline’ Year 2000 technology, ‘Reference’ Y2020 technology, without Clean Sky benefits, and finally the ‘Conceptual’, reflecting Y2020 technology with Clean Sky benefits. The results of this study i llustrate the potential that incorporated technologies possess in terms of improving performance and gas emission metrics such as fuel burn, CO2, NOx as well as the noise footprint on the ground

Left-dominant arrhythmogenic cardiomyopathy in a Fila Brasileiro dog

Background: In human medicine, arrhythmogenic left ventricular cardiomyopathy was described as a primary disease of the heart characterized by fibroadipose replacement of the myocardium..Case Description: We report the case of a dog, with history of syncope and irregular cardiac rhythm. Electrocardiogram, echocardiography, and a 24-hour Holter monitoring showed, respectively, the presence of premature ventricular complexes with right bundle branch block morphology, an increase of the left ventricle end-diastolic diameter with preserved fractional shortening and ejection fraction, and a sinus arrhythmia as baseline rhythm with supraventricular tachycardia episodes and ventricular complexes with left bundle branch block morphology. After the death of the canine, a postmortem examination showed cardiomegaly. Fibroadipose replacement of the septum and both ventricles,with left ventricle myocardial fibrosis, suggestive of previous necrosis, was observed.Conclusion: These findings are suggestive of left-dominant arrhythmogenic cardiomyopathy which, to the best of our knowledge, has not been described in veterinary medicine

An FPGA Kalman-MPPT implementation adapted in SST-based dual active bridge converters for DC microgrids systems

The design of digital hardware controllers for the integration of renewable energy sources in DC microgrids is a research topic of interest. In this paper, a Kalman filter-based maximum power point tracking algorithm is implemented in an FPGA and adapted in a dual active bridge (DAB) converter topology for DC microgrids. This approach uses the Hardware/Software (HW/SW) co-design paradigm in combination with a pipelined piecewise polynomial approximation design of the Kalman-maximum power point tracking (MPPT) algorithm instead of traditional lookup table (LUT)-based methods. Experimental results reveal a good integration of the Kalman-MPPT design with the DAB-based converter, particularly during irradiation and temperature variations due to changes in weather conditions, as well as a good balanced hardware design in complexity and area-time performance compared to other state-of-art FPGA designs

Measurement of the cosmic ray spectrum above 4×10184{\times}10^{18} eV using inclined events detected with the Pierre Auger Observatory

A measurement of the cosmic-ray spectrum for energies exceeding $4{\times}10^{18}$ eV is presented, which is based on the analysis of showers with zenith angles greater than $60^{\circ}$ detected with the Pierre Auger Observatory between 1 January 2004 and 31 December 2013. The measured spectrum confirms a flux suppression at the highest energies. Above $5.3{\times}10^{18}$ eV, the "ankle", the flux can be described by a power law $E^{-\gamma}$ with index $\gamma=2.70 \pm 0.02 \,\text{(stat)} \pm 0.1\,\text{(sys)}$ followed by a smooth suppression region. For the energy ($E_\text{s}$) at which the spectral flux has fallen to one-half of its extrapolated value in the absence of suppression, we find $E_\text{s}=(5.12\pm0.25\,\text{(stat)}^{+1.0}_{-1.2}\,\text{(sys)}){\times}10^{19}$ eV.Comment: Replaced with published version. Added journal reference and DO

Una hipótesis sobre el incremento del precio del limón en México, 2022

In the first quarter of 2022, the price of lemons reached retail prices never before recorded in the Mexican economy. Despite the fact that Mexico is the second largest producer of lemons internationally, a kilogram was sold for up to $120 Mexican pesos (approximately 6.00 US dollars) in popular markets and supermarkets. This situation caused anger in Mexican households because lemons, in addition to being part of the basic food basket, are the basis of many daily dishes and are commonly used to treat and cure various ailments and diseases. Therefore, the objective of this paper is to propose a hypothesis about the increase in the price of lemons in Mexico based on a mismatch between supply and demand. For this purpose, national statistics on production, consumption, and exports were reviewed to delimit this market mismatch. It is concluded that the preference of large producers to place their product in foreign markets that pay in dollars, as well as an unexpected boom in the consumption of lemons and their pharmaceutical derivatives to prevent and cure COVID-19 in the United States, are responsible for the market mismatch.En el primer trimestre de 2022 el precio del limón alcanzó precios al menudeo jamás antes registrados en la economía mexicana. Pese a que México es el segundo productor de limón a nivel internacional, el kilogramo se llegó a vender hasta en$120 pesos mexicanos (aprox. 6 dólares americanos) en mercados populares y supermercados. Esta situación provocó encono en los hogares mexicanos pues el limón, más allá de formar parte de la canasta básica, es base de múltiples platillos cotidianos y es común su uso para tratamiento y cura de distintos males y enfermedades. Por lo anterior es que este trabajo tiene como objetivo proponer una hipótesis sobre el incremento del precio del limón en México basada en un desajuste de la oferta y la demanda. Para ello se revisaron estadísticas nacionales de producción, consumo y exportaciones para delimitar dicho desajuste de mercado. Se concluye que la preferencia de los grandes productores por colocar su producto en mercados extranjeros que pagan en dólares, así como un inesperado auge de consumo de limón y derivados farmacéuticos de este para prevenir y curar el COVID-19 en Estados Unidos, son los responsables del desajuste de mercado.

Contrasting the semantic typology biases of Deaf and hearing nonsigners in their conceptualization of time and space

The mental lexicon offers a window into the configuration of conceptual domains such as space and time, which has been labeled as concrete the former and abstract the latter in the current embodiment approach to cognition. Space has a phonological and semantic value in sign languages, but not in spoken languages. Additionally, the representation of time by spatial means is robust in oral and sign languages. This research asks if Deaf signers and hearing nonsigners have the same conceptual organization of those domains. In their respective languages, sixty-two participants made a repeated free word association task. These results showed that the studied populations have a little overlap in the associates evocated for each clue. The analysis of the preferences of the semantic relations of the pairs clue-associate showed a greater tendency of the Deaf signers to establish thematic relations. In contrast, the hearing participants indicated a bias toward taxonomic relations. The results suggest that the abstractness or concreteness of concepts may be modulated by factors associated with linguistic modalities. However, in this compared free association norms factors related to the language deprivation of Deaf, the asymmetries in the cross-modal language contact and cross-modal borrowing were not exhaustively controlled.Fil: Macedo, María Noel.
