Implementation and validation of the harmonic balance method for temporally periodic non–linear flows

An efficient method for tackling non-linear, temporally–periodic incompressible flows is presented in this paper. Assuming temporally fully periodic flow, Harmonic Balance method deploys Fourier transformation in order to formulate transient problem as a multiple quasi-steady state problems. The method is implemented in OpenFOAM and developed for a general transport equation and incompressible Navier–Stokes equations. Validation is presented on three test cases: oscillating scalar case for scalar transport validation, a flow around a 2D NACA airfoil and a 3D Onera M6 wing for turbulent incompressible Navier–Stokes validation. For all test cases Harmonic Balance results are compared to transient simulation results. Verification of the model is performed by changing the number of harmonics for all test cases.Copyright © 2016 by ASME
Trace Fossils with Spreiten from the Late Ediacaran Nama Group, Namibia: Complex Feeding Patterns Five Million Years Before The Precambrian–Cambrian Boundary

Abstract Here we describe large, complex trace fossils in the late Ediacaran Omkyk Member of the Zaris Formation, Nama Group, southern Namibia. The horizontal trace fossils are preserved on a number of talus blocks from a bedding plane of a cm-thick sandstone lens from a single stratigraphic horizon less than 100 m below an ash bed dated at 547.3 ± 0.7 Ma. The forms consist of overlapping U-shaped spreiten elements with parallel limbs surrounded by an outer tube. Individual U-shaped elements are 0.2 to 1 cm in diameter, the outer tube is less than 3 mm in diameter, and the forms as a whole range from 5 to 30 cm long and 3 to 10 cm wide. The specimens commonly show a change in direction and change in diameter. The morphology of these trace fossils is comparable to backfill structures, particularly specimens of Paleozoic Zoophycos from shallow water environments. Here we interpret these horizontal spreiten-burrows to record the grazing of the trace-maker on or below a textured organic surface. The identification of large late Ediacaran trace fossils is consistent with recent reports of backfilled horizontal burrows below the Precambrian–Cambrian boundary and is suggestive of the appearance of complex feeding habits prior to the Cambrian trace fossil explosion.
Beyond Photo realism

For around 30 years the computer graphics research community has pursued photorealism as though it were the ultimate form of visual expression. Yet, as an art form, photorealism is one of many abstractions that an artist might use to convey ideas, shape, structure, emotion and mood. In this paper we de­ scribe how techniques and wisdom learned from photorealistic computer graphics can be adapted and applied to a diverse range of alternative styles for visual expression.
Emotional Creativity (EC) among Pre-Service and In-Service Trainee Teachers.

The teachers of today are facing multidimensional challenges in their profession. The increasing expectations of society, new sources of learning and teaching, technological innovations, increasing intelligence level of students are some of the burning issues to cope up in front of them. The teacher of tomorrow is expected to deal with not only on the frontiers like ICTs and virtual system of education, but have to prove there importance as a human element of the process. In order to cope up with these challenges, a teacher should be emotionally creative, because the time has changed. In current scenario, a teacher should be more courteous to students and should deal with them in a friendly environment. In the personality of a teacher, emotional creativity is an integral part.
Synthesis and Characterization of nZVI Grafted Alumina and Its Application for Fluoride Removal from Drinking Water: Equilibrium and Kinetics Study

In the present study attempt was made to synthesize iron nanoparticles in the presence of alumina (Al-nZVI) by sodium borohydride reduction process. The composite adsorbent has been characterized using various analytical techniques such as scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction and transmission electron microscopy which showed that iron nanoparticles were partially dispersed on alumina surface, with their diameter being in the range 40–100 nm. The batch adsorption experiments were carried out to study the effect of different parameters. The maximum removal of fluoride was obtained at optimal condition of pH 5.0 and dose = 1.8 g/L and was observed to be 94% with contact time of 60 min at 40 °C and initial concentration of 2 mg/L. The adsorption data fitted that pseudo second order kinetics and followed Langmuir isotherm model with maximum adsorption capacity of 10.06 mg/g. Thermodynamic study revealed exothermic nature of adsorption.
Study on the Relationship Between Emotion Tropism and Expressivity of College Students and Their Mental Health

The method of scaling is adopted to study the relation between emotional tropism (consisting of positive and negative affective variables), emotional expressivity and mental health by doing questionnaires from 263 college students in Chongqing City. The differences test shows that: (a) Males express more negative affect than females and are not as good as women in expressing their feelings, but no significant gender differences in positive affect and feeling of happiness is observed; and freshmen share more feeling of happiness than seniors, but no significant differences between grades in their expression of positive or negative affect and emotions are observed; (b) Correlation analysis shows that feeling of happiness and other positive affect have significant negative correlation with most of the psychological symptom factors, while negative affect have significant positive correlation with all the psychological symptom factors; and emotional expressivity shows significant negative correlation with interpersonal sensitivity, hostility, depression, anxiety and other factors; (c) Regression analysis further shows that negative affect exerts significant regression effect on obsession, interpersonal relationship, depression, anxiety, hostility, bigotry and other factors, and emotional expression exerts regression effect on interpersonal sensitivity, hostility, depression, anxiety and other factors.
Mining New Translation Lexicons from Wikipedia

In this paper, we propose a method of mining new translation lexicons from Wikipedia. To do this, first a network is constructed with nodes representing Wikipedia articles and links representing the dependencies between the articles. Then we learn a model of translation lexicons by investigating co-occurrence patterns of the existing translation lexicons in a Wikipedia network. Finally, new translation lexicons can be found by estimating the cross-lingual similarities between the nodes in different languages. Experiments show that our method effectively finds new translation lexicons.
Un nuevo sistema para detectar la distracción y la somnolencia utilizando el tiempo de tecnología de vuelo para vehículos inteligentes

Nowadays, most countries in the world suffer several traffic issues which generate public health problems such as deaths and injuries of drivers and pedestrians. In order to reduce these fatalities, a system for automatic detection of both distraction and drowsiness is presented in this research. Artificial intelligence, computer vision and time of flight (TOF) technologies are used to compute both distraction and drowsiness indexes, in real time. Several experiments have been developed in real conditions during the day, inside a real vehicle and in laboratory conditions, to prove the efficiency of the system.
Teaching Hardware to Demystify Foundational Software Concepts

: Both top-down and bottom-up approaches have been proposed for software and programming education. Motivations can be cited for both approaches, but empirical data for either approach can be difficult to obtain. In this paper, we explore potential benefits of a bottom-up approach which begins at the architecture and machine language level. Abstractions of basic software concepts such as data storage and pointers can lead to misconceptions. Understanding how these abstractions are implemented in the underlying hardware can provide clarity of foundational software concepts. An introductory course on embedded systems and microcontrollers for electrical and computer engineers was modified in an attempt to strengthen student understanding of foundational software concepts. The material covered in the course primarily remained the same, but the course schedule was modified to move the system architecture and instruction set material to the beginning of the course, rather than the end. Data was collected for common exam questions for offerings both prior to and following the course modification. The data indicates that students who were exposed to the functionality of the underlying architecture prior to high-level programming languages had a better understanding of basic concepts such as storage allocation and referential pointers. This paper contributes to the fields of education in electrical and computer engineering and computer science by providing data on student outcomes for alternate approaches to content delivery. We hope that this information is useful in curriculum design and development for related fields.
Role of Transparent Exopolymer Particles on Phytoplankton Dynamics in a Subtropical Estuary, Cananéia-Iguape (SP, Brazil)

Transparent Exopolymer Particles (TEP) has a known crucial role in vertical fluxes of carbon in the ocean and has been intensively studied in the last decade. Nevertheless, few studies have considered horizontal fluxes of TEP. These fluxes arise prominently between estuaries and the coast, where its importance is associated to the predominant horizontal transport. This is due both to the low density of the TEP agglomerate generated in low density waters of continental origin, and to the fact that the main component of the advective transport at estuarine regions is the horizontal one. In this study, the significance of TEP in the particulate matter exchange between estuary and coast was analyzed in the estuarine lagoon system of Cananeia-Iguape (southeast coast of Brazil). TEP, total seston (TS), organic seston (OS) and chlorophyll a (Chl.a) were analyzed over complete tidal cycles, during the dry and rainy seasons both at spring and neap tides. Horizontal fluxes and net transport rates of these variables were also calculated. TEP concentrations (max. 4991 µg Xeq/L) were almost one order of magnitude higher during the rainy season. TEP horizontal transport rates as high as 1.8 g Xeq·m/s were observed at the northern inlet of the system. In terms of particulate carbon, it represents 32.7 g TEP-C m/s or 4% of the OS transport rates. Our study quantifies the advective transport of TEP and their importance in particulate matter exchange between a subtropical estuarine system and the adjacent coastal region. Our results contribute to the knowledge of exopolimer particles dynamics in subtropical estuarine systems, and their relationship to phytoplankton biomass and particulate matter.
The Search of the Equality Across Educational Policies: scopes and limits / La Búsqueda de la Igualdad a través de las Políticas Educativas: Alcances y Límites

Este artículo examina el papel de la educación en la reducción de la desigualdad social y económica. Aunque la relación positiva entre el nivel educativo de un individuo y su sueldo sugiere que la igualación del acceso a educación resultará en una distribución económica más semejante, estructuras sociales y económicas muy desiguales pueden disminuir el poder del sistema educacional para aumentar la igualdad. Dos puntos claves emergen de este discurso: (1) La única manera de reducir la desigualdad social y económica es seguir políticas que igualen con eficacia la distribución de recursos y riquezas en la sociedad y (2) la calidad de la educación y el acceso a la misma puede tener un efecto significativo sobre la desigualdad económica y social.El autor examina varias reformas educativas y cómo éstas pueden o no contribuir a una mayor igualdad en la distribución de la educación y, por tanto, a una mayor igualdad económica y social. Las reformas menos eficaces incluyen reformas “estructurales” como la descentralización y la privatización. Reformas para mejorar la calidad de los profesores—como aumentar las horas que los profesores enseñan, igualar la distribución de la calidad de los profesores, y aumentar la capacidad de los profesores—han demostrado conseguir mayor igualdad educacional. Aunque estas reformas son más costosas y políticamente más difíciles que otras que se han implementado durante los últimos veinte años, representan la mejor oportunidad para hacer que la educación aumente la igualdad social y económica.
Biomass of karst evergreen and deciduous broad-leaved mixed forest in central Guizhou province, southwestern China: a comprehensive inventory of a 2 ha plot

The biomass of a secondary evergreen and deciduous broad-leaved mixed forest was comprehensively inventoried in a permanent 2 ha plot in southwestern China. Biomass models, sub-sampling, soil pit method, and published data were utilized to determine the biomass of all components. Results showed that the total biomass of the forest was 158.1 Mg ha−1; the total biomass included the major aboveground (137.7 Mg ha−1) and belowground (20.3 Mg ha−1) biomass components of vascular plants as well as the minor biomass components of bryophytes (0.078 Mg ha−1) and lichens (0.043 Mg ha−1). The necromass was 17.6 Mg ha−1 and included woody debris (9.0 Mg ha−1) and litter (8.6 Mg ha−1). The spatial pattern of the aboveground biomass was determined by the spatial distribution of dominant trees with large diameter, tall height, and dense wood. The belowground biomass differed in terms of root diameter and decreased with increasing soil depth. The belowground biomass in each soil pit in local habitats was not related to the spatial distribution of woody plants and soil pit depth. The karst forest presented lower biomass compared than the nonkarst forests in the subtropical zone. Biomass carbon in the karst terrains would increase substantially if degraded karst vegetation could be successfully restored to the forest. Comprehensive site-based biomass inventory of karst vegetation will contribute not only to provide data for benchmarking global and regional vegetation and carbon models but also for regional carbon inventory and vegetation restoration.

Chiral partner structure of heavy baryons from the bound state approach with hidden local symmetry

The chiral partner structure of heavy baryons is studied using the bound state approach by binding the heavy-light mesons to the nucleon as the soliton in an effective Lagrangian for the pseudoscalar and vector mesons based on hidden local symmetry. In the heavy-light meson sector, we regard the $H$ doublet and $G$ doublet as chiral partners and couple them to light mesons with a minimal derivative. We find that the chiral partner of ${\ensuremath{\Lambda}}_{c}(\frac{1}{2}\genfrac{}{}{0}{}{{}^{+}}{},2286)$ is the ${\ensuremath{\Lambda}}_{c}(\frac{1}{2}\genfrac{}{}{0}{}{{}^{\ensuremath{-}}}{},\frac{3}{2}\genfrac{}{}{0}{}{{}^{\ensuremath{-}}}{})$ heavy quark doublet with a mass of about 3.1 GeV but not (${\ensuremath{\Lambda}}_{c}(\frac{1}{2}\genfrac{}{}{0}{}{{}^{\ensuremath{-}}}{},2595)$, ${\ensuremath{\Lambda}}_{c}(\frac{3}{2}\genfrac{}{}{0}{}{{}^{\ensuremath{-}}}{},2625)$), which might be interpreted as an orbital excitation of ${\ensuremath{\Lambda}}_{c}(\frac{1}{2}\genfrac{}{}{0}{}{{}^{+}}{},2286)$. The same model is applied to the bottom sector, and the chiral partner of ${\ensuremath{\Lambda}}_{b}(\frac{1}{2}\genfrac{}{}{0}{}{{}^{+}}{},5625)$ is shown to have a mass of about 6.5 GeV. We also discuss the chiral partner structures for the isospin vector heavy baryons. For the pentaquark states, we find that the masses of the pentaquark state made of a ground state heavy-light meson and its chiral partner are similar, and both of them are below the $Dp$ threshold, which therefore cannot be ruled out by the present data.
Stochastically Optimal Groundwater Management Considering Land Subsidence

This paper presents a stochastic groundwater management model explicitly considering land subsidence. Through the use of response matrix technique and one-dimensional consolidation equation, a deterministic management model is first developed. By Latin hypercube sampling technique, along with numerical subsurface flow simulation, statistical features of unit response coefficients due to random hydrogeologic parameters, including hydraulic conductivity K and Lame constants and , are quantified. The first-order- variance-estimation method is adopted to analyze the uncertainties of drawdown and land subsidence based on which the concept of chance-constrained programming is applied to transfer the original deterministic management model into its stochastic form. The stochastic management model enables the determination of optimal total pumpage subject to the constraints that drawdown and land subsidence do not exceed the allowable values with a specified reliability. A hypothetical example is utilized to demonstrate the applica- bility of the stochastic model to five cases in which various levels of parameter uncertainty are considered. The results indicate that joint consideration of drawdown and land subsidence is essential, and the proposed stochastic management model can be generally applied for regional groundwater resources management in conjunction with controlling land subsidence.
On holomorphic sections of Veech holomorphic families of Riemann surfaces

We give upper bounds of the numbers of holomorphic sections of Veech holomorphic families of Riemann surfaces. The numbers depend only on the topological types of base Riemann surfaces and fibers. We also show a relation between types of Veech groups and moduli of cylinder decompositions of flat surfaces.
Morals and the Right to Free Movement

Abstract This article examines the right to free movement in the European Union (EU) and discusses the moral questions related to refugees in light of the current migration context. More specifically, in this article, I discuss the right to free movement in terms of its development into an EU citizenship right and assess the grounds for its validity. I argue that free movement was developed in a manner that puts too much emphasis on external threats coming from outside the EU borders. I also claim that the right to free movement is an exclusive concept that adds to the alienation between EU-citizens and the rest, which is also visible in the ongoing so-called migration crisis.
Vitamin D Status and Its Association with Age and Gender in East Sikkim

Organization/World Health Organization3 expert consultation, regions located between 42°N and 42°S latitude receive abundant sunshine, which is responsible for the cutaneous production of vitamin D. In spite of experiencing ample sunlight, the deficiency is highly prevalent in India affecting all age groups and genders.1 The synthesis of vitamin D is largely affected by the latitude, sun exposure, seasons, atmospheric pollution, dress code, and skin pigmentation.4,5 Sikkim, a northeastern state of India, lies in the latitude between 27°N and 28°N6 and previous studies have reported high prevalence of hypovitaminosis D in northern parts of India with a latitude of 27°N.7-9 Studies have proven an association between low circulating vitamin D level with increased risk of diabetes, common cancers, hypertension, autoimmune, and infectious diseases. Some studies have highlighted that if the daily consumption of vitamin D is 1100 IU for a period of 4 years, it has found to decrease occurrence of cancers.10,11 The most reliable indicator for determining vitamin D deficiency is serum 25-hydroxyvitamin D, [25(OH)] D,12 and radioimmunoassay is the common method for the estimation.13 There are no published data regarding the occurrence of vitamin D deficiency in Sikkim, hence, we aim to estimate the vitamin D level in patients attending a tertiary care hospital in East Sikkim, India.
An improved method for successive data schism and interpolation

This paper presents an improved type of data schism and interpolation called Alnuaimy-Mahamod Interpolation based on the mean and variance to calculate the entire point between two known points. A new mathematical method is developed for interpolation from a given set of data points in a plane and for fitting a smooth curve to the points. This method is devised in such a way that the resultant curve will pass through the given points and will appear smooth and natural. Data schism and interpolation describes the behaviors of the calculated points which behave as bacteria reproduction. This type of interpolation based on calculation of the mean and the variance of two adjacent points and modify of these calculate values by named factors to be used to calculate the entire points. Our type of interpolation can be working as linear midpoint interpolation, linear interpolation and smooth curve fitting.
JaSPEx: Speculative Parallel Execution of Java Applications ?

Multicore processors, capable of running multiple hardware threads concurrently, are becoming common on servers, desktops, lap- tops, and even smaller systems. Unfortunately, most of the time these new machines are underutilized, as most current software is not written to take advantage of multiple processors. Also, with these new machines, more cores do not translate into more sequential performance, and exist- ing sequential applications will not speed up by moving to a multicore. To tackle this problem, we propose to use thread-level speculation based on a Software Transactional Memory to parallelize automatically sequen- tial programs. We describe the JaSPEx system, which is able to do auto- matic parallelization of existing sequential programs that execute on the Java Virtual Machine, and we address the problem of transactifying an existing program and the diculties inherent to this process. Besides the transactication process, we describe how speculation is introduced and controlled by the JaSPEx system, and what is the relationship between the speculative execution of a program and the Software Transactional Memory that it is using.
The Role of the Offices of Information and Communication Technology (ICT) in the Rural Sustainable Development of Meshkinshahr Township

The present research aims at surveying the role of ICT offices in sustainable development of Meshkinshahr rural areas. This research is descriptive- analytic and data collection has been done through library resources and internet searches along with surveying methods. The data gathered are analyzed by SPSS software. The sample population includes 234 persons from 14 selected villages having ICT offices. Findings and regression results indicate positive effects of ICT offices on villagers' use of services, marketing, products matched with market needs, paving way for new jobs, rise in income, creation of jobs related to ICT, increasing opportunities, capacities, and variation in rural economy, empowerment, negative effect of electronically used services, creation of local markets, production of new handicrafts, establishment of mentally light activities, reduction in migration, keeping university graduates, effective and balanced use of basic resources, and participation. The findings resulted show that the villagers have used information services and especial services of offices less than the basic services. Thus, regarding various facets at village level, the effect of ICT offices has not been very comprehensive.
