Noise suppression based on auditory-like filters for robust speech recognition

An efficient noise suppression algorithm for speech signals is presented; it is based on auditory-like filters. The algorithm processes in three steps. First, the noise spectral energy is estimated after corrupted speech is input into a set of auditory-like filters. A statistical estimation method based on multi-band filters is proposed and compared with the weighted average. The second step is to eliminate the estimated noise spectrum from the observed signal by spectral subtraction. Finally, an auditory-based feature is extracted from the enhanced signal and introduced into the ASR system. The noise suppression algorithm is evaluated in a speaker-dependent Chinese digit experiment and experimental results show that the proposed algorithm can improve the automatic speech recognition performance in a noisy environment.
Las plantas en la poesía de Góngora: (en el tricentésimo nonagésimo aniversario de su muerte)

espanolLa poesia de todos los tiempos utiliza como metaforas de algunas caracteristicas humanas propiedades o aspectos de los vegetales. No es extrano encontrar que el rubor de las mejillas se defina como el color de los petalos de una rosa. La poesia barroca en general y Gongora en particular usan estos recursos con enorme prodigalidad pero, en la poesia de Gongora, la metafora vegetal adquiere muchas veces un valor funcional que posee una clara base cientifica EnglishThe poetry of all times uses as metaphors of some human characteristics several properties or aspects of plants. It is not uncommon to find that the flush of the cheeks can be defined as the color of the petals of a rose. Baroque poetry in general and Gongora in particular use these resources with enormous prodigality but, in Gongora's poetry, the vegetal metaphor often acquires a functional value that has a clear scientific basis.
An RF cascode BJT-LNA with shunt-series input matching

An RF low noise amplifier (LNA) is proposed using BJT cascode topology to provide gain with low bias current consequently lower power dissipation and lower noise figure (NF). The circuit was designed and simulated with SPICE using a bipolar model card. At 1 GHz, the LNA noise figure is 1.87 dB, forward gain is 14.3 dB, reverse isolation is -60 dB, and excellent third order intermodulation intercept point (IIP3) of 3 dBm are obtained. The LNA consumes 2.3 mA from a 2 V power supply.
Avaliação da eficiência do processamento de água de coco por micro-ondas

PINTO, R. O. M. Evaluation of the eficiency of microwave processing of coconut water. 2017. 57f. Dissertação (Mestrado) – Faculdade de Ciências Farmacêuticas, Universidade de São Paulo, São Paulo, 2017. Coconut water, as currently marketed, is sterilized and added with chemical preservative or antioxidant, which reduces its sensory and nutritional qualities. In order to avoid these undesired effects, the heating of coconut water through microwaves radiation has been studied, which would allow a drink of better sensorial quality and without addition of preservatives or with reduced amount of these substances. The objective of this study was to evaluate the viability of the pasteurization of coconut water by microwave, using spores of B. coagulans as biological indicator of the process. Spores of B. coagulans CCGB (LFBFIOCRUZ) 1433 were inoculated in samples of coconut water, obtained directly from green fruits (Cocos nucífera L.) and previously acidified (ascorbic and citric acid), followed by pasteurisation using microwaves with frequency of 2450 MHz. The tests, from a Rotational Composite Central Design, with 4 variables (temperature, quantity and composition of the acids and power of the microwave apparatus) were carried out randomly, with a process time of up to 20 minutes. The tests were conducted with 3 replicates of the central point. The conventional heating process was also carried out in order to compare the two methods. Inactivation results were expressed as log of spores /mL of coconut water. Temperature is the preponderant factor for the process of pasteurization of coconut water through the analysis of the DCCR. It was also possible to observe that, under the following conditions: a) power of 120W; b) 76 mg of acids added to the beverage and c) composition of acids of 22% ascorbic and 78% citric acid, the results were separated into two groups: one group at a temperature of 86 °C, where the reduction of the spore population was lower (between 0,5 log and 3,7 log of spores/mL of coconut water), and another one at a temperature of 92 °C, which presented higher logarithmic reductions of the microorganism (between 3,4 log and 7,0 log of spores/mL of coconut water). Once the ANOVA test was performed, it was verified that the predicted increase was significant. There was a difference statistically significant between conventional and microwave heating. However, this difference was not taken into account because microbiologically it could be neglected. As for processing time, an average of 10 to 15 minutes of retention at the desired temperature is required to achieve the highest level of inactivation of spores at the center point conditions (89 °C, 125 W, 75 mg of acids added to the cocnut water and the composition of acids of 75% cítrico e 25% ascórbico). The pasteurisation of coconut water by microwave has proved to be feasible, but other studies are needed to optimize processing.
Power Based Performance and Capacity Estimation Models for Enterprise Information Systems.

A variety of dependency formalisms have been studied for improving data quality. To treat these dependencies in a uniform framework, we propose a simple language, Quality Improving Dependencies (QIDs). We show that previous dependencies considered for data quality can be naturally expressed as QIDs, and that different enforcement mechanisms of QIDs yield various data repairing strategies.
Adopting game technology for architectural visualization

Schroeder, Scott A. M.S., Purdue University, May 2011. Adopting Game Technology for Architectural Visualization. Major Professor: Clark A. Cory. Current methods to display a new home in the architectural visualization industry involve long render times and hundreds of frames that require rendering. Many times, these virtual tours that are produced are slow, methodical, and limit the viewer's perspective of the home. This research looks into using computer game engines to display the virtual tour in real time, thus removing the long render time requirements and limited viewer perspective.

Technical Strategies and Surgical Results of C1 Lateral Mass-C2 Pedicular Screw Fixation in Atlantoaxial Disorders

Objective: There are various posterior fusion techniques in managing C1-2 instability. The aim of this study is to evaluate surgical techniques and clinical results including complications of the C1 lateral mass and C2 pedicle screw fixation (C1-2 LMPSF) in atlantoaxial disorders. Methods: From February 1997 to July 2008, 24 patients were performed C1-2 LMPSF due to C1-2 instability. Pathway of vertebral artery was classified into three groups by 3D-angiogram. Diameter of C1 lateral mass and C2 isthmus on the plain X-ray and CT was measured before operation. Surgical method was divided into four groups according to fixation site (bilateral or unilateral) and bone graft (with or without graft). Stability of C1-2 fixation was postoperatively evaluated by flexion and extension cervical lateral films. We reviewed clinical data, imaging studies and old chart retrospectively as sources for analysis. Results: Among 24 patients, os odontoideum was the most common cause (16 out of 24). Four patients had anomalous vertebral artery. Mean diameters of C1 lateral mass was 9.9(range 4.2~16.4) mm at right side, 10.3 (range 3.4~14.2) mm at left side. Mean diameter of C2 isthmus was 5.8 (range 1.0~10.1) mm at right side and 5.8(range 2.1~8.2) mm at left side. Two patients showed very narrow C2 isthmus. As a result, unilateral C1-2 LMPSF was performed on 6 patients (4 for anomalous vertebral arteries and 2 for narrow C2 isthmus). 12 of 18 patients were with C1-2 interlaminar bone graft and 6 patients without bone graft. All patients showed stable C1-2 fixation by flexion and extension cervical lateral X-ray films taken at least 6 months after surgery. Five out of 8 patients who had preoperative radiculopathy only showed improved symptoms. However, Seven out of 8 patients who had myelopathy showed little neurological improvement . Conclusion: For C1-2 LMPSF, preoperative 3D CT-angiogram study is mandatory to identify abnormal vertebral artery and narrow C2 isthmus. Bilateral C1-2 LMPSF without bone graft is enough to obtain stable C1-2 fixation. If there is an abnormal vertebral artery or narrow C2 isthmus, unilateral C1-2 LMPSF with bone graft and wiring is alternative successful method.
Proposal of two solutions to cope with the faulty behavior of circuits in future technologies

Device scaling in new and future technologies brings along severe increase in the soft error rate of circuits, for combinational and sequential logic. Although potential solutions are being investigated by the community, the search for circuits tolerant to radiation induced errors, without performance, area, or power penalties, is still an open research issue. This work proposes two solutions to cope with this unpredictable behavior of future technologies: the first solution, called MemProc, is a memory based architecture proposed to reduce the fault rate of embedded microcontrolled applications. This solution relies in the use magnetic memories, which are tolerant to radiation induced failures, and reduced combinational circuit area to improve the reliability when processing any application. The second solution proposed here is an infrastructure IP implementation for the MIPS architecture indicated for reliable systems-on-chip due to its fast adaptation and different levels of application hardening that are allowed. The second solution is also indicated for systems where neither the hardware nor the software can be modified. The experimental results show that both solutions improve the reliability of the system they take part with affordable overheads and even, as in the case of the MemProc solution, improving the performance results.
Diversity-multiplexing tradeoff for multiaccess channels

The amount of diversity and the total number of degrees of freedom are two important resources in a wireless system. Traditionally they have been considered in isolation. In recent work [l], a new point of view is proposed: the performance of communication schemes can be described as a tradeoff between the amount of these two resources actually utilized. The optimal tradeoff achievable by any scheme provides then a fundamental benchmark with respect to which actual schemes can be judged. In [l] the optimal tradeoff curve for the point-topoint MIMO Rayleigh fading channel was computed. In this talk. we extend this result to the MIMO multiaccess channel. Figure 1: Optimal point-tepoint diversity-multiplexing tradeoff. 11. FORMULATION AND MAIN RESULT
OLIGODONCIA: REPORTE DE UN CASO CLÍNICO

Las anomalias dentales son alteraciones que se producen durante la odontogenesis en la se afecta la forma, el tamano, la disposicion, el grado de desarrollo y el numero de los dientes. Dentro de estas anomalias de numero, la agenesia dental se presenta con frecuencia. La oligodoncia se caracteriza por la ausencia congenita de mas de seis dientes y puede presentarse en la denticion primaria y permanente; se asocia comunmente con sindromes o algunas alteraciones sistemicas. Los terceros molares son los dientes mayormente afectados, seguidos por los segundos premolares inferiores y los incisivos laterales superiores. Esta entidad es mas comun en mujeres y en el maxilar inferior. En el presente articulo se reporta el caso de una joven de 13 anos de edad quien acude a la Clinica de Odontopediatria de la Universidad Nacional Autonoma de Mexico con ausencia congenita de los organos dentales del 12,17,18, 22, 27,28, 35, 37,38,45, 47 y 48. Dicha ausencia no se asocio con algun tipo de sindrome que tenga dentro de sus caracteristicas la ausencia dental. Por tal motivo, se establecio un diagnostico presuntivo de oligodoncia no sindromica verdadera y se planteo llevar a cabo un tratamiento que cumplia con las necesidades que el caso requiera mediante la interaccion multidisciplinaria de diferentes especialidades odontologicas.

Early Childhood’s Antibiotic Use and Risk of Allergic Diseases

This review considers the knowledge on the colonization of the infant’s gut with beneficial bacteria starting from early days of life. This colonization drives the developing, but immature, immune system of the infant though the local, intestinal, well-regulated, immune mechanisms, to tolerogenic immune response and “no-disease” state. This response in characterized by TH1 predominance. Any a perturbation of this homeostasis by environmental factors such as antibiotics, “swings back” the immune response towards TH2 response, increasing the propensity to develop allergic inflammation, and clinical allergic diseases. There is emerging evidence to support the role of intestinal microbiota in developing allergic disease. At clinic level, there is vivid research to determine role of antibiotics exposure in developing allergic diseases such as asthma, allergic rhinitis, eczema, and food allergy. The results of studies appear as if they are inconsistent or even conflicting. However, this inconsistency seems to be related to some methodological factors in evaluating the host, exposure, outcome and confounders. Still, the three is clear evidence that antibiotic exposure during prenatal period, infancy, or early childhood is associated with high risk of allergic diseases and asthma during infancy, childhood or early adolescence. This risk is governed by individual’s genetic background & place of residence, type and dose of antibiotics. It is quite important to remember, that antibiotics exposure or use is only one of the risk factors of increased risk of allergy among children and does not exclusively account for this rise.
Text in localization in natural scene images using multiple classifiers

Localization of text areas in images of natural scenes is essential for many applications, including support for the blind, tourist support, traffic control and content-sensitive image or video databases. Algorithms for localization of scene text must overcome issues of non-uniform scene lighting, scene text variations and distortions etc. In the paper we present the results obtained for scene text detection algorithms operating on various image representation domains, as well as our work on an algorithm based on an ensemble of simple classifiers.
An Overview of Automatic Question Generation Systems

Question Generation from text is Natural Language Processing task. It involves a joint effort between Natural Language Understanding (NLU) and Natural Language Generation (NLG). Automatic Question Generation (AQG) is the task of generating reasonable questions from an input, which can be structured (e.g. a database) or unstructured (e.g. a text). An AQG system would be useful for building an automated trainer for learners to ask better questions, and for building better hint and question asking facilities in intelligent tutoring systems. Another benefit of AQG is that it can be a good tool to help and to improve the quality of the Question Answering (QA) systems. Tackling AQG in the field of computational linguistics has got immense attention from the researchers. This review paper draws on recent developments in NLP research to look at the evolution of automatic Question Generation Systems in a new light.
Comparison of Sports Coverage in Book Review Digest and Book Review Index

To discover if review sources are keeping up with the pro liferation of sports books, bicycling, hiking, fishing (fresh water), tennis, golf, and canoe, kayak, or river run were selected as representative sports to examine. The study was limited to reviews for 580 books appearing in Book Re view Digest (BRD) and Book Review Index (BRI) between 1970 and 1980. It was found that these major review index ing sources have not kept pace with the tremendous growth of interest in sports books. With the exception of 1971, the number of sports books published each year since 1970 has increased, but every year since 1970 has seen a decrease in the percentage of sports books reviewed. Out of the total sample of 580 books, BRD contained only 1 book review that was not also in BRI. The number of books on the fastest growing sports being reviewed has increased more than the number of most popular sports books being reviewed. Of the total sample, 36 percent were reviewed by sources indexed by BRI, 8 percent by sources indexed by both BRI and BRD, and 0.2 percent by sources indexed by BRD.
