In recent decades, cloud image classification has become a research hotspot in the field of weather forecasting. Initially, cloud images that fall on various climate zones are categorized based on their regions. Dimensionality reduction is performed in the cloud images by applying Principal Components Analysis (PCA) to enhance the classification accuracy of cloud images. The proposed system uses the training set to learn the features of cloud images and classifies the test case images into low, medium and high. The experimental results are obtained by implementing the INSAT weather image data set using MATLAB tool. The proposed methodology can be used in various applications like Rainfall Prediction, Oceanography and Cyclone Forecasting.

Judo is technical combating game that is based on the biomechanical practices and lies in the category of most probable traumatic &injurious games. Judo is all about throwing the opponent to win the bout. Uke (defender) continuouslymake efforts to defend himself from being displaced or to take advantage of Tori’s (attacker) body weight shifting by counter attacking through reversing the transferred force back to Tori with added strength and misbalanced him. As a defender, Uke try to avoid the back fall as this leads to loss of bout completely. This unusual evasion greatly invites the Judo trauma as a result of sudden twisting of Uke body in avoiding back fall. The injuries like abrasion, sprain or muscle strain are common during practices and are temporary. The major injuries like spine & head injuries that can cause the paralysis or memory loss and breakage ofHumerus (upper arm of shoulder) or disjoint of tibia in knee, elbow damage can spoil the carrier of Judoka as he cannot fight back in original form after such injuries. Therefore a prudent observation of probable injuries, their classification and association with Judo techniques is quite significant. Bayes’ classification can easily predict that which class of techniques like hip techniques, hands or legs techniques, throwing techniques, joint lock techniques or the choking techniques is more prone to particular set of specified injuries while playing by males or females under 3 categories of weight say lightweight, middle weight and high weight. Such study is beneficial to Judokas and coaches to avoid possible injuries. For this purpose, the research paper apply Bayes’ theorem to classify the conditional probabilities of 3 different classes of Judo injuries C1, C2 and C3 by taking 17 different Judo techniques under different Judo techniques classes, for instance,Ashi-Waza, Te-Waza, Kansetu-Waza, Sutemi-Waza and Shime-Waza in training data to compute posteriori. The tatami (Judo Mat) quality to absorb the pressure & reduce the risk of Judo traumas is also highlighted. For the further scope of the study, other behavioralaspects like attitude and beliefs that influences the Judokas performance, their learning &position winning arealso reflected.

The tissues and level of tissue in the organ may require for physician assessment. The proposed work is used to detect the tissue level in lungs. An early detection of tissue may leads to detect the cancer cell. The RGB color input image is converted into gray scale image. The gaussian noise is applied on the gray image. The median filter is applied to project the tissue pixels. The canny edge detection is applied on the filtered image to detect the boundary regions. The gradient magnitude operation is performed to project the edges of tissue. A watershed transform is applied on the gradient image to perform the morphological operation. A morphological area open and area close operation is performed along with reconstruction which highlights the tissue area from the lungs. Super imposing morphology with the regional maximum pixel operation is performed to differentiate tissue pixels. The tissue area is retained and all other area pixels are replaced by logic ‘0’ pixels using Otsu’s global thresholding method. The tissue portion is cropped using the OAD regions.

Power system stability is one of the major factors for the reliable operation of electric utilities. Factors resulting power system instability are the sudden increase in load or insufficient reactive power support. Efficient Voltage regulation methods enable the system to operate in a stable operating condition. Many methods reported in the literature for voltage stability assessment of the power system such as optimization method, continuation power flow method, Indices based method and Artificial Intelligence based methods. Several iterative methods are used for the solution of load flow problems. The major disadvantages of iterative methods are larger iteration and increase in convergence time which depends on size of the power system. This paper proposes new method for voltage profile assessment on distribution system using Generalized Regression Neural Network. The Power System Analysis Toolbox (PSAT) is used for Distribution power flow solution. The proposed method is tested using 52 buses, distribution system of Tirunelveli, Tamil Nadu India. The technical feasibility of the proposed method is verified by comparing the results of proposed method and PSAT.

Internet of Things (IoT) is growing at an exponential rate but the area of privacy and security in IoT still remains unexplored. The existing algorithms or methods are mainly centralized and hence they are vulnerable due to their single point authentication topology. As it has been estimated that by 2020 there will be more ‘things’ than people on this earth the problem of security becomes a major concern in IoT networks, as a person having control to an IoT network will be able to control a large portion of an organization. Blockchain has recently been used to provide security to peer-to-peer networks. Blockchains are computationally expensive, heavyweight and are considered unsuitable for IoT architecture. In this paper a new lightweight and secure architecture for IoT by using Ethereum Blockchain retaining most of its security providing powers is proposed. Since Blockchain is decentralized it solves the single point authentication problem existing in IoT networks. A Smart Home System as a representative case study has been implemented for broader IoT applications. The two parameters measured are temperature and intrusion detection. The proposed model tackles some more challenges that exist in IoT networks. The Qualitative evaluation of the proposed architecture highlights how it tackles various attacks.

Published: August 2019

Las interacciones entre el corazón y el riñón se han convertido en un área de considerable interés, dada la interdependencia de los mismos. Esto motivó la definición y conceptualización del síndrome cardio-renal anémico, que incluye interacciones bidireccionales, donde alteraciones, tanto agudas como crónicas de cualquier órgano, pueden afectar indistintamente la función renal o la ventricular. El tratamiento, involucra el bloqueo del eje renina angiotensina aldosterona y durante una descompensación aguda es válido el soporte dialítico para control de la volemia. La anemia, es multifactorial, se debe tratar de manera oportuna con hierro endovenoso y eritropoyetina recombinante, reduciendo al mínimo el soporte transfusional. El manejo, la definición y el pronóstico del síndrome cardio-renal anémico aún sigue siendo controversial y es un reto para el internista moderno

Precise local control of liquid crystal pretilt on polymer layers by focused ion beam nanopatterning
Authors: Gorkunov Maxim V , Kasyanova Irina V , Artemov Vladimir V , Mamonova Alena V , Palto Serguei P
Published: August 2019

Background: The alignment of liquid crystals by surfaces is crucial for applications. It determines the director configuration in the bulk, its stability against defects and electro-optical switching scenarios. The conventional planar alignment of rubbed polymer layers can be locally flipped to vertical by irradiation with a focused ion beam on a scale of tens of nanometers.

Results: We propose a digital method to precisely steer the liquid crystal director tilt at polymer surfaces by combining micrometer-size areas treated with focused ion beam and pristine areas. The liquid crystal tends to average the competing vertical and planar alignment actions and is stabilized with an intermediate pretilt angle determined by the local pattern duty factor. In particular, we create micrometer-sized periodic stripe patterns with this factor gradually varying from 0 to 1. Our optical studies confirm a predictable alignment of a nematic liquid crystal with the pretilt angle continuously changing from 0° to 90°. A one-constant model neglecting the difference between the elastic moduli reproduces the results quantitatively correctly.

Conclusion: The possibility of nanofabrication of polymer substrates supporting an arbitrary (from planar to vertical) spatially inhomogeneous liquid crystal alignment opens up prospects of “imprinting” electrically tunable versatile metasurfaces constituting lenses, prisms and q-plates.
Saha Ionization Equation in the Early Universe
Authors: Das Aritra , Ghosh Ritesh , Mallik S.
Published: August 2019

The Saha equation follows from thermal equilibrium of matter and radiation. We discuss this problem of equilibrium in the early universe, when matter consists mostly of electrons, protons, and hydrogen atoms. Taking H atoms in their ground state only and applying the real-time formulation of thermal field theory, we calculate the difference of ionization and recombination rates, which controls the equilibration of H atoms. By comparing with realistic calculations including the excited states of the H atom, we conclude that the presence of excited states lowers the equilibrium temperature from 5000 to 4000 K.
Smoothing of MHD Shocks in Mode Conversion
Authors: Pennicott Jamon D. , Cally Paul S.
Published: August 2019

Shock waves are simulated passing through the Alfvén-acoustic equipartition layer in a stratified isothermal magneto-atmosphere. The recent ray-theoretic calculations of Núñez predicted smoothing of the shock through this layer, causing both the fast and slow components to emerge as continuous waves. However, it is found that the partial mode conversion expected from linear theory for oblique incidence of the shock on the magnetic field is accompanied by a smoothing of the slow shock only, while the fast shock persists. Explanations are presented based on magnetohydrodynamic mode conversion and shock theory.
Reconnection Front Associated with Asymmetric Magnetic Reconnection: Particle-in-cell Simulations
Authors: Song Liangjin , Zhou Meng , Yi Yongyuan , Deng Xiaohua , Zhong Zhihong
Published: August 2019

Reconnection front (RF) has frequently been observed in the magnetotail and is well known as the dipolarization front in the near-Earth tail. Whether the RF exists in reconnection with distinct plasma/field properties across the reconnecting current sheet (i.e., asymmetric reconnection) is unknown yet. In this Letter, we use 2.5D particle-in-cell simulations to investigate the properties of RF in asymmetric reconnection and compare to RFs in symmetric reconnection. We find that RF is a robust structure in asymmetric reconnection. Its moving speed and thickness are smaller than those in symmetric reconnection. Its properties, such as the current density, electromagnetic field structure, are examined. Some features of RF in asymmetric reconnection are drastically different than those in symmetric reconnection. These results are of great help for studying RF in plasma environments with asymmetric reconnection, such as Earth’s magnetopause.

Electromyogram signals have been used for various applications in the healthcare sector for developing various methodologies and techniques in rehabilitation and prosthetics. This paper focuses on the use of EMG signals of trans-radial amputees for developing a myoelectric lower limb prosthesis capable of individual finger movement. The aim of this work is to develop proper hardware and software systems for real-time EMG classification. An improved double thresholding method for onset and offset detections has been developed to ensure its applicability in real-time. The proposed algorithm has been tested with real-time patient EMG signals using a three-lead electrode system from flexor digitalis region of the hand. Around 3000 samples of usable data corresponding to the flexion of each finger (Thumb-553, Index-655, Middle-723, Ring-720, Little-655) were acquired from 10 healthy subjects. The resultant extracted features were classified using various classifiers (KNN, KNN with PCA and LDA) and a comparison was done between the accuracies acquired from a commonly shared dataset against a subject-specific dataset. A robust onset signal processing algorithm enabled the real-time classification of EMG in noisy environments.

Objetivo: apreender as representações sociais de jovens estudantes sobre a prevenção em HIV/Aids. Métodos: trata-se de pesquisa exploratória, qualitativa, guiada pela Teoria das Representações Sociais, em três escolas de Ensino Médio da rede pública, com 70 estudantes, de ambos os sexos e idades entre 18 e 29 anos. Para a coleta de dados, utilizou-se instrumento baseado na técnica de associação livre de palavras, com termo indutor “prevenção em HIV/Aids. As evocações foram lematizadas, codificadas e processadas pelo software EVOC, versão 2005. Resultados: os dados apontaram um número maior de jovens do sexo feminino (57,14%), negros (84,28%), heterossexuais (92,85%) e que já tinham iniciado a atividade sexual (95,71%). O núcleo central apresentou os termos “camisinha, doença, prevenção e sexo” como estruturantes das representações sociais dos jovens acerca da prevenção em HIV/Aids. Conclusão: a ideia de prevenção situa-se no uso do preservativo, enquanto tecnologia disponível, frente a doenças transmitidas pela prática sexual desprotegida. Logo, espera-se que as práticas sexuais entre jovens aconteçam de forma segura, prazerosa e responsável.

Published: August 2019

Behçet disease is a chronic, relapsing-remitting autoinflammatory syndrome with a strong HLA-B*51 association. In this paper, we describe a human cohort of 267 individuals with Behçet disease and 445 matched controls from a tertiary referral center in the U.K. HLA-B*51 was confirmed as a genetic risk factor in this group (p = 0.0006, Bonferroni–Dunn correction for multiple testing [Pc] = 0.0192, odds ratio [OR] 1.92, 95% confidence interval [CI] 1.33–2.76). KIR3DL1/S1 allele-level analysis indicated that low-expressing KIR3DL1/S1 alleles in combination with KIR3DS1 increased the risk of developing Behçet disease (KIR3DL1LOW/KIR3DS1: p = 0.0004, Pc = 0.0040, OR 2.47, 95% CI 1.43–4.25), whereas high-expressing KIR3DL1/S1 alleles in combination with a null-expressing KIR3DL1 reduced the risk of disease (KIR3DL1HIGH/KIR3DL1NULL: p = 0.0035, Pc = 0.0350, OR 0.53, 95% CI 0.33–0.87). Behçet disease can manifest as a purely mucocutaneous disease or can involve other organ systems such as the eyes. In the U.K. cohort studied in this study, KIR3DL1LOW/KIR3DS1 increased the risk of ophthalmic disease (p = 1.2 × 10−5, OR 3.92, 95% CI 2.06–7.47), whereas KIR3DL1HIGH/KIR3DL1NULL reduced the risk of having purely mucocutaneous disease (p = 0.0048, OR 0.45, 95% CI 0.25–0.81). To our knowledge, this is the first analysis of KIR3DL1/S1 allelic variation in Behçet disease and may provide insight into the pathogenic role of HLA-B*51 and its interaction with KIR3DL1/S1.

Hypermetabolism of basal ganglia in chorea associated with antiphospholipid antibodies demonstrated by F-18 FDG
Authors: Sathekge M. M. , Maes A. , Thijst V. , De Roo M.
Published: August 2019

A brain FDG PET study was performed on a 21-year-old woman with subacute chorea of unknown origin. Associated with her chorea, she had abnormal levels of antiphospholipid antibodies. She had none of the classical features of SLE nor primary antiphospholipid syndrome. The images showed high F-18 FDG uptake in the basal ganglia, while the brain MRI and EEG were normal. An association between chorea and antiphospholipid antibodies had been demonstrated before, with normal brain CT, MRI, 123IMPSPECT and cerebral angiography. The report suggests the advantage of FDG PET in imaging of unexplained cases of chorea associated with antiphospholipid antibodies.
