A Minimized MIMO-UWB Antenna with High Isolation and Triple Band-Notched Functions
Authors: Kong Yuanyuan , Li Yingsong , Yu Kai
Published: August 2016

A compact high isolation MIMO-UWB antenna with triple frequency rejection bands is proposed for UWB communication applications. The proposed MIMO-UWB antenna consists of two identical UWB antennas and each antenna element has a semicircle ring shaped radiation patch fed by a bend microstrip feeding line for covering the UWB band, which operates from 2.85 GHz to 11.79 GHz with an impedance bandwidth of 122.1 %. By etching a L-shaped slot on the ground plane, and embedding an “anchor” shaped stub into the patch and integrating an open ring under the semicircle shaped radiation patch, three notch bands are realized to suppress WiMAX (3.3–3.6 GHz), WLAN(5.725–5.825 GHz) and uplink of X-band satellite (7.9–8.4 GHz) signals. The high isolation with S21<–20 dB in most UWB band is obtained by adding a protruded decoupling structure. The design procedure of the MIMO-UWB antenna is given in detail. The proposed MIMO-UWB antenna is simulated, fabricated and measured. Experimental results demonstrate that the proposed MIMO-UWB antenna has a stable gain, good impedance match, high isolation, low envelope correlation coefficient and good radiation pattern at the UWB operating band and it can provide three designated notch bands.

Published: August 2016

In this work, a methodology to measure torque during dough mixing in large scale was developed and the baking performance of bread dough formulated with resistant starch (RS) and enzymes was evaluated. Dough was formulated with 12.5 g/100 g of RS and 4 mg/100 g of a mixture of enzymes, glucose-oxidase (Gox), tranglutaminase (TG) and xylanase (HE) in proportions according to a three-component mixture design of experiments. Dough was mixed in a large-scale dynamic rheometer measuring instant torque and speed in real time through a personal computer (PC) interface. Maximum torque during mixing and parameters of the dough development curves obtained from rheofermentometer were fit to mathematical models within 95 % of confidence. Gox and TG showed positive effects on the maximum height of dough, while HE showed a negative one. Also, it was found that Gox and TG in the presence of HE could be important for reducing dough weakening.
Care support points of Mecklenburg-West Pomerania. Results of a scientific analysis / Pflegestützpunkte in Mecklenburg-Vorpommern. Ergebnisse einer wissenschaftliche Analyse
Authors: Schmidt Stefan , Kraehmer Steffi
Published: August 2016

Background

In the period 2011 – 2013, 13 care support points were set up in Mecklenburg-West Pomerania. They are the joint responsibility of all health and long-term care insurance funds and local government.

Method

Between July and November 2013, data on organisation and personnel were collected in respect of the care support points and their advisory staff. Questions were asked about reasons for visiting a care support point, the subject matter of any counselling and demographic data on the users. Data were collected using questionnaires and interviews. Descriptive statistics were used to analyse quantitative data, the interviews were evaluated by analysis of their content.

Results

The results show a heterogenic picture of adviser training. Most users made contact with the care support points by telephone. General information on long-term care insurance was frequently sought. In 2015, care support points were consulted much more frequently than in 2014. The partners describe the networking involved as time-consuming; any synergy effects to date were estimated to be limited.

Conclusions

More network structures need to be created if those in need of care and assistance as supplied by care counselling based on case management are to be reached in future. What is called for are firm, written contracts with no personal bias, assigning care support points with the role of central actors at the regional level, able to produce neutral, independent organization and coordination of the necessary assistance. A guarantee of continuity of provision would fulfill the requirements of the kind of procedure involved in case management. Regardless of the number of professional providers and informal carers participating.
Compounding errors: why heightened regulation and taxation are bad antidotes for recessions and income inequality
Authors: Epstein Richard A
Published: August 2016

The current concerns with laggard growth and income inequality have led to a widespread set of demands for more regulation and higher taxation to reverse the trend. These two approaches move matters exactly in the wrong direction. The correct response is to find ways to reduce tax burdens and barriers to entry, and to reduce the political uncertainty associated with new government measures. It may well be too late, worldwide, for a substantial rollback in the welfare state. But the current proposals will only prolong the dismal results on both fronts in any arena in which they are tried.

O objetivo desse estudo foi comparar as curvas de sensibilidade ao contraste de adultos e idosos. Foi medida a FSC para grades senoidais verticais utilizando o método psicofísico da escolha forçada (2AFC). Participaram desse estudo 18 adultos com idade entre 20 e 29 anos e 18 idosos com idade entre 60 a 69 anos, de ambos os sexos. A ANOVA mostrou efeito principal entre os grupos [F(1, 156) = 173,160; p < 0,001] e de interação entre as frequências espaciais e a idade [F(3,427) = 163,365; p < 0,001]. Já o teste Bonferroni mostrou diferenças significantes em todas as frequências testadas (p < 0,001). Verificou-se que o padrão da curva de SC se mantém com o envelhecimento, com a menor sensibilidade localizada nos extremos da curva e a maior sensibilidade localizada próxima ao centro da curva. Além disso, sugere-se alterações no processo senso perceptivo visual ao longo da vida.

Vitimização é a experiência de violência. Ela pode ocasionar sequelas físicas e psicológicas e aumentar a vulnerabilidade do indivíduo sofrer outras vitimizações. A autoeficácia é a crença que o indivíduo tem sobre sua capacidade de produzir os resultados desejados em determinada situação. O objetivo deste estudo foi elaborar e investigar as primeiras evidências de validade e precisão da Escala de Autoeficácia Relacionada à Experiências de Vitimização, em uma amostra de 210 estudantes universitários. A escala foi elaborada com 17 itens, retidos após análise de conteúdo. Análise Fatorial Exploratória e Análise Paralela indicaram a pertinência da solução unifatorial (15 itens), com boa precisão α = 0,88. Através do Modelos de Créditos Parciais descreveu-se os parâmetros dos itens e características dos participantes (dificuldade/theta, índices de ajustes infit/outfit), assim como a invariância dos parâmetros dos itens em função do sexo dos participantes, o que demonstrou adequação do instrumento para avaliação do construto em questão.

Published: August 2016

O objetivo deste estudo foi investigar o envolvimento paterno de 35 pais (18 a 40 anos), cujo filho tinha 12 meses de vida. Os pais responderam a uma entrevista e as suas respostas foram examinadas através de análise de conteúdo qualitativa, com base em três dimensões do envolvimento paterno: interação, disponibilidade e responsabilidade. Os pais relataram se envolver com o filho de acordo com as necessidades e habilidades específicas dos 12 meses, idade em que o bebê passa a ser mais responsivo. Contudo, alguns pais relataram não ter a habilidade necessária para cuidar de um bebê, o que pode contribuir para um menor envolvimento com o filho. Os resultados do estudo evidenciam que os pais mostraram-se competentes para lidar com um bebê com novas habilidades, mesmo que, em alguns momentos, eles parecessem sentir dificuldades ou ainda preferissem que a mãe realizasse determinadas atividades.

DESCOLONIZR A EDUCAÇÃO: Os Mestres dos Saberes Populares e Tradicionais no contexto da formação cultural
Authors: Nunes Neto Francisco Antônio
Published: August 2016

O texto problematiza a importância dos diálogos estabelecidos entre as esferas formais e não-formais no processo de formação cultural. Para tanto, entende a valorização e introdução dos saberes dos mestres da cultura popular como um desafio posto às instituições escolares. Aos nossos dias ainda vigora, em larga medida, um modelo de formação escolar baseado numa tradição livresca de cuja matriz epistemológica foi herdada, sobretudo de países europeus. Neste sentido, o artigo provoca-nos a pensar sobre os novos desafios postos à educação contemporânea à medida que discute a falência do modelo de formação acadêmica seja no âmbito da Escola Básica ou como praticado na maior parte das faculdades e universidades brasileiras que ao não valorizar os saberes populares locais, subalterniza-os, contribuindo na perpetuação de uma hierarquia entre conhecimento e sabedoria.

In this article, some actual problems regarding the education department of Punjab province are presented. Mostly all of them are observed by the author himself during his duty during Govt. survey for admission policy for gaining hundred percent targets. For this purpose, first survey was done for U.S.E. (Universal primary Education), while second survey was completed for U.S.E. (Universal Secondary Education). In both surveys, after getting complete information about the children regarding their particulars, they knew that how many children are remaining to get education. In this way, targets were set for every school under union councils for admissions in primary and secondary levels. During survey, different problems had to face to whom, who were doing door to door survey of concerned villages in village areas and concerned streets in city areas. Some of children’s parents behaved in inhuman behavior about giving particulars of their children. Some of them did not inform about their daughters’ particulars. In short, level of education is attached with economic condition of the developing countries.
Dengue, Zika and Chicungunha: The use of a mathematic concept to develop an educational game for helping on fighting important viral diseases
Authors: Dutra T. , Costa D.P. , Barboza C.F.S. , Alves L. , Castro H.C.
Published: August 2016

Dengue is the leading cause of viral death worldwide. The vector Aedes aegypti mosquito is also responsible for Zika and Chincungunha transmission, another very compromising viral diseases. As the understanding of the vector life cycle and its habitat is important for preventing and fighting against these diseases, we propose to use a mathematic concept, graphos, and a problem-based situation (the removal of potential breeding sites for mosquitoes in the player city) to design a computational game that may help on spreading information and to stimulate a players proactive virtual and real behavior. Thus this paper describes the design and construction of an educational computer game called "Graphos against mosquitos," based on graphos, a mathematics theoretical concept. We designed the Graphos game using as the main elements: a child, twelve neighborhood blocks, mosquitoes, streets and containers where mosquitoes lay eggs (tires, cans, bottles, plants with water deposits). In the game, the player (Avatar) is the main element that should "walk in" the streets (edges) of the city, removing the potential breeding grounds for mosquitoes in each block (vertices). As this game is based on the mathematics theoretical concept graphos using two dimensions, the city has two distinct vertices that are the beginning and end of it, which discriminate the beginning and end of the game. The player should remove all containers of each street, avoiding mosquitoes growth and passing only one time for each of them. As containers are removed, the player gains points and is prevented to return to the previous street. In this game the removal of all containers that pose risk of becoming mosquito breeding sites, without coming back to the previous street but only forward, is translatable into " graphos language". When finishing the game properly, it opens a final screen where the player is awarded with a medal. On this screen, the player can write his/her name, being invited to act as a "health worker" no longer in virtual form, but in the real life. Through teaching by using computational material ruled by mathematical concepts such as graphos, we hope to stimulate and contribute for fighting and controlling the vector of these serious viral diseases.

The modes are classified into three types: rotational, translational, and planetary component modes. All vibration modes fall into one of these three categories. The unique properties of each type is examined which is analytically verified with candidate mode method. Furthermore, the work investigates effects of parameters, which include stiffness, mass, moment of inertia and crankshaft eccentricity, on natural frequencies of three vibration modes and crankshaft eccentricity is in particular scrutinized. It is helpful for understanding the relationship between parameters and vibration modes.

Authors: Zhang Nan
Published: August 2016

From the point of view of frequency capture, the nonlinear dynamic models of the self-synchronous vibrating pile system are presented for the analysis of the nonlinear stiffness of the soil, which is induced by the relationship between the nonlinear stress and the strain in the soil. And the nonlinear dynamic models of the self-synchronous vibrating pile system with electromechanical coupling also are presented for the analysis of the pile- soil- electric coupling. The nonlinear characteristics of the vibrating pile in the self-synchronous vibrating pile system with frequency capture are analyzed, and the periodic solutions for the self-synchronous system with frequency capture are investigated using the nonlinear models. The synchronization condition for the self-synchronous vibrating pile system with frequency capture is theoretical analyzed using the rotor-rotation equations of the two-excited motors, and the synchronization stability condition also is theoretical analyzed using Jacobi matrix of the phase difference equation of the two-excited motors. Using Matlab/Simlink, the reverse rotation synchronization of the two-excited motors and the stability of synchronization of the self-synchronous vibrating pile system with electromechanical coupling are analyzed through the selected parameters. The nonlinear phenomena in the self-synchronous vibrating pile system with electromechanical coupling, such as frequency capture and the limit cycles, are reproduced. Various synchronous phenomena are obtained through the difference rates of the two-excited motors, which are induced by the relationship between the phases of the two-excited motors and the rotation speeds of the two-excited motors. It has been shown that the research results can provide theoretical basis for the design and research of the self-synchronous vibratory system.

Authors: Li Wei , Ji Leilei , Shi Weidong , Zhou Ling , Jiang Xiaoping , Zhang Yang
Published: August 2016

In this study, the flow field and impeller structure response in the mixed-flow pump are cooperative solved based on the bidirectional synchronization solving method, to study the vibration characteristics of the mixed-flow pump impeller rotor under the fluid-structure interaction. The pressure distributions of blade surface in the mixed-flow pump under different flow rate conditions were compared, and the deformation, equivalent stress distribution and natural vibration frequency of impeller blade under static force load were studied. Meanwhile, the deformation of impeller blade and coupling stress distribution was analyzed based on bidirectional fluid-structure interaction. The results show that the deformation of impeller blade increases from hub to rim, and the maximum deformation occurs at the rim of the blade. The stress distribution of impeller blade in the circumferential direction is symmetrical, and the maximum equivalent stress occurs at the blade outlet edge near the hub. The maximum deformation position and the stress concentration location are basically consistent before and after coupling calculation, but the maximum deformation value increases and the maximum equivalent stress value decreases under the fluid-structure interaction. The influence of water pressure on the strength and frequency of vibration is very limited. With the increase of flow rate, the maximum equivalent stress of impeller decreases and the total deformation increases gradually. The results of this research provide reference basis for the structure design and reliability analysis of the mixed-flow pump.

Authors: Xue Jianfeng , Shen Peihui , Wang Xiaoming
Published: August 2016

To address the ricochet problem in penetration process, the mathematical model of projectile penetrating into concrete target is established according to the basic kinetic equation and surface layer mechanism. The motion trajectory of projectile nose is obtained. Experimental studies on projectiles with different nose penetrating into concrete targets are conducted to explain the ricochet problem. These studies analyze fifty-four penetration conditions under different initial velocities and oblique angles when the projectiles have flat, hemispherical, ogive noses and conical noses. The regularity and critical angles of ricochet are analyzed with different nose shapes at different velocities. Results show that the ricochet angle increases depending on nose sharp and penetration velocity. The factors affecting the ricochet from big to small were analyzed via orthogonal test. The results show that with increasing the velocity from 652 m/s to 1022 m/s, the critical angle increases from 44° to 66°. The order of factors affecting the ricochet from big to small is the shape of the nose, the material of the projectiles and the penetrating velocity respectively.
Enhancement of two-dimensional acoustic source identification with Fourier-based deconvolution beamforming
Authors: Yang Yang , Chu Zhigang , Shen Linbang , Ping Guoli
Published: August 2016

When utilizing conventional regular focus point distributions to define a relatively large source region, Fourier-based deconvolution beamforming, an attractive acoustic source identification technique, would suffer from some limitations: 1) significantly deteriorative location and quantification accuracy for sources away from the center of the focus region; 2) pronounced sidelobe contaminations. The arch-criminal is the assumption that the point spread function (PSF) is definitely shift-invariant over the entire focus region fails to be satisfied well. This paper focuses on remedying these limitations for two-dimensional (2D) acoustic source identification. First and foremost, a novel focus point generation approach is introduced, which can generate unconventional irregular 2D focus point distributions tending to make PSF more shift-invariant. Additionally, a sidelobe suppression approach is suggested. Effects of these approaches are examined both with computer simulations and experimentally. This study provides the feasibility of using Fourier-based deconvolution beamforming to accurately and efficiently identify acoustic sources in a relatively large region.
