A precarização do trabalho, o REUNI e o novo desenvolvimentismo
Authors: Andrade Antonia Costa , Lucena Carlos , Barleta Ilma Andrade
Published: May 2018

Este artigo ao centralizar-se nos governos FHC e Lula e a ressignificação do neodesenvolvimentismo, tomou o REUNI como referência, em termos educacionais, com o objetivo de realizar um estudo comparativo entre os referidos governos, respaldado nas mudanças no neodesenvolvimento e seus impactos na sociedade e na educação. A pesquisa foi dividida em duas partes: a primeira analisa o governo FHC e os primórdios da implantação do Plano Real. A segunda, por sua vez, debate o governo Lula, demonstrando seus pressupostos, continuidades e rupturas com o governo FHC e uma ênfase final no projeto de expansão do ensino superior público denominado REUNI. Foram pesquisadas fontes primárias manifestas em jornais da época, documentos governamentais e análise do discurso dos principais atores políticos do projeto em questão. O que demonstramos é que o governo Lula não rompeu com a lógica monetarista inerente ao governo FHC, no qual houve expansão do ensino superior privado, manifestando projetos precarizantes do trabalho dos professores. No governo Lula, o processo de interiorização da Universidade pública manifestou a contradição do acesso a alunos no ensino superior, porém em condições também precárias para o desenvolvimento da Ciência e Tecnologia.

Essa temática conta com raras   produções nas áreas de história e de educação e constitui-se relevante para a história da educação sobre as experiências socialistas. O artigo inclui reflexões sobre a história da URSS; o processo de aprendizagem dos partidos comunistas; a produção ocidental a respeito dos relatos de viagem e a difamação enrustida de imparcialidade científica.
Escolas multisseriadas rurais no Estado do Tocantins e pedagogia histórico-crítica: aproximações
Authors: Nunes Klívia de Cássia Silva , Bezerra Maria Cristina dos Santos
Published: May 2018

O presente trabalho aborda as práticas pedagógicas existentes nas escolas multisseriadas de 08 povoados rurais do município de Tocantinópolis/TO a partir da perspectiva dos docentes. Tomamos como referência de análise a Pedagogia Histórico-Crítica (PHC) tendo como fio condutor o seguinte questionamento: como os professores se posicionam diante das práticas pedagógicas que desenvolvem nas escolas multisseriadas rurais? Os dados aqui apresentados foram coletados no decorrer de um projeto de extensão integrado a pesquisa sobre o ensino em salas multisseriadas para o qual optou-se pela realização da pesquisa teórica e de campo. O resultado, ainda que provisório, proporcionou uma visão geral sobre a prática dos professores das escolas multisseriadas rurais no município estudado, que em suas falas demonstraram receber pouca orientação e subsídios sobre didática que facilitem trabalhar nestas escolas. Constatou-se também que há necessidade de adotar uma visão mais crítica na formação dos filhos dos trabalhadores do campo, de forma que compreendam a situação de dominação atual e, vemos na Pedagogia Histórico Crítica um referencial teórico-prático que possibilita desenvolver esse tipo de formação que vai além do trabalho escolar, preparando o indivíduo para sua inserção social pautada em conteúdos sólidos.
A leitura no Brasil Colônia e suas (inter)relações com a contemporaneidade
Authors: Sousa Gustavo Borges , Carvalho Luciana Beatriz Oliveira Bar , Carvalho Carlos Henrique de
Published: May 2018

O entendimento da leitura e da produção de livros no Brasil pode ser visto como um processo de construção social a partir do modo de colonização arbitrado pela metrópole portuguesa. Diante disso, a formação intelectiva do brasileiro teve perdas, uma vez que lhe foi impedido o acesso a construções ideológicas importantes e ganhos, porque teve que driblar as peias coercitivas impostas pela pátria lusitana. Pero Vaz de Caminha, Gregório de Matos, Tomás Antônio Gonzaga foram alguns dos nomes que conseguiram na contemporaneidade a valorização justa em função não só da qualidade textual de suas obras, mas do esforço em serem escritores em um país de poucos leitores e, principalmente, incentivos ligados à intelectualidade. Neste sentido, percebe-se a colonização do país não só como exploratória, mas também como inibidora do processo emancipatório do brasileiro. O reflexo disso, na literatura atual, é a reprodução de situações que marcam a construção sócio-histórica do país desde sua base colonial. Portanto, para compreender o hoje, faz-se necessário revisitar o ontem.

Published: May 2018

Estudo transversal realizado com o objetivo de avaliar a capacidade instalada para o fortalecimento do Sistema de Segurança Alimentar e Nutricional (Sisan) em cinco municípios do estado de Sergipe, por meio de coleta de dados direta e pesquisa documental. Foram utilizados dois instrumentos para coleta de dados: check list sobre o Sistema Nacional de Segurança Alimentar e Nutricional, proposto pela gestão nacional, e uma matriz de indicadores de Segurança Alimentar e Nutricional (Sisan), proposta pela Universidade Federal da Bahia, ambos adaptados à realidade do estado de Sergipe. Os resultados mostraram a frágil capacidade instalada para o sistema nos municípios que já o tem implantado; a necessidade de maior interesse dos gestores pela adesão ao sistema, nos territórios que ainda não o aderiram, e pelas ações de SAN em suas respectivas localidades; necessidade de fortalecer a participação da sociedade civil na luta para a efetivação destas políticas. Os resultados retrataram também o risco de Insegurança Alimentar em todos os municípios estudados, reforçando a necessidade do Sistema. Ressalta-se a relevância de fortalecer o Sisan nos municípios que já o aderiram, e implantar naqueles que ainda não aderiram, considerando que será exequível o monitoramento das ações e programas de SAN.
Preço de hortaliças orgânicas segundo canal de comercialização
Authors: Arantes Rafael Rioja , Recine Elisabetta
Published: May 2018

O estudo comparou os preços de hortaliças provenientes de sistemas de produção orgânica e convencional em quatro canais de abastecimento com características distintas em Brasília-DF. Os preços de 25 alimentos foram coletados em dois períodos, novembro de 2015 e abril de 2016, nos seguintes locais: duas feiras ecológicas “de rua”, galpão da agricultura familiar e Mercado Orgânico, ambos localizados na Central de Abastecimento (CEASA-DF) e em três grandes supermercados concorrentes. As análises verificaram as diferenças absoluta e relativa de preços dos orgânicos entre si, e dos orgânicos com os convencionais dos supermercados. Foi constatado que hortaliças orgânicas comercializadas em supermercados chegam a custar mais que o triplo do preço em relação às orgânicas de canais alternativos, e que a cesta contendo os 16 alimentos pesquisados chega a custar mais que o dobro nos supermercados. No comparativo geral com as convencionais, ainda que estas custem mais barato, as orgânicas apresentaram preços competitivos e inclusive menores dependendo do canal. O estudo indica que são relativamente enganosas as afirmações e a divulgação de informações relativas aos preços de alimentos orgânicos que não considerem a pluralidade dos canais de abastecimento.

Este estudo teve como objetivo analisar o cardápio das escolas indígenas de Piaçaguera - SP, quanto ao respeito aos hábitos alimentares e à frequência de produtos ultraprocessados.  Trata-se de um estudo de caso, realizado na Terra Indígena Piaçaguera, em Peruíbe - SP, onde foram visitadas quatro escolas. A Comissão Pró-índio de São Paulo disponibilizou materiais com informações sobre Piaçaguera e os hábitos alimentares locais, e seis cardápios mensais da alimentação escolar de 2016. Os cardápios foram analisados por refeição (desjejum e almoço) quanto à presença e a combinação de alimentos tradicionais do hábito indígena, e um dos cardápios foi analisado quanto à frequência de produtos ultraprocessados. Foi encontrada uma preparação tradicional para cada refeição, uma vez por semana, porém a combinação com outros alimentos não se adequava ao costume indígena. Os ultraprocessados foram encontrados diariamente no desjejum, alguns dias de forma exclusiva, e de 2 a 3 vezes por semana no almoço. Portanto, os cardápios escolares não condizem com os hábitos alimentares de Piaçaguera e os ultraprocessados estiveram frequentemente presentes, predominantemente no desjejum. É necessário que o planejamento do cardápio da alimentação escolar considere a variedade de alimentos tradicionais e valorize os saberes e o patrimônio alimentar indígena.

Purpose: Our aim was to evaluate the effects of problem-solving skills training (PSST) on self-control behaviors and the positive and negative psychotic symptoms of schizophrenia in community-dwelling patients.Method: This quasi-experimental study was conducted in 63 adult community-dwelling outpatients with schizophrenia in Taiwan. The control group (n=28) received routine life skills training alone, while the experimental group (n=35) received both routine life-skills and problem-solving training. The data were collected at four time points (at baseline, and at week 6, 12, and 16 [4 weeks after training ended]). This study measured outcome variables including problem-solving skills (using the Self-control Schedule [SCS]), and psychiatric syndromes (using the Positive and Negative Syndrome Scale [PANSS]).Results: Our generalized estimating equation (GEE) model showed a significant improvement in the self-control behavior score in the experimental group at week 12 and 4 weeks after training ended, compared with the control group. In addition, the negative symptoms score was significantly improved at week 12 and 4 weeks after training end, compared with baseline.Conclusion: These results demonstrated that PSST and routine living skills training have a positive impact on the negative symptoms of schizophrenia patients and could improve their problem-solving capacity and skills for dealing with daily life and health problems and could moderate negative psychotic symptom severity.
A Measure of Information Available for Inference
Authors: Isomura Takuya
Published: May 2018

The mutual information between the state of a neural network and the state of the external world represents the amount of information stored in the neural network that is associated with the external world. In contrast, the surprise of the sensory input indicates the unpredictability of the current input. In other words, this is a measure of inference ability, and an upper bound of the surprise is known as the variational free energy. According to the free-energy principle (FEP), a neural network continuously minimizes the free energy to perceive the external world. For the survival of animals, inference ability is considered to be more important than simply memorized information. In this study, the free energy is shown to represent the gap between the amount of information stored in the neural network and that available for inference. This concept involves both the FEP and the infomax principle, and will be a useful measure for quantifying the amount of information available for inference.
Spatio-temporal Features of Urban Heat Island and its Relationship with Land Use/Cover in Mountainous City: A Case Study in Chongqing
Authors: Liu Chunxia , Li Yuechen
Published: May 2018

The urban heat island (UHI) becomes more and more serious with the acceleration of urbanization. Many researchers have shown interest in studying the UHI by using remote sensing data. But these studies rarely examine the mountainous cities. The studies on UHI in mountainous cities often used empirical parameters to estimate the land surface temperature (LST), and lacked satellite-ground synchronous experiment to test the accuracy. This paper revised the parameters in mono-window algorithm used to retrieve the LST according to the characteristics of mountainous cities. This study examined the spatial and temporal patterns of the UHI intensity in Chongqing, a typical mountainous city, and its relationship with land cover from 2007 to 2011 based on the Landsat TM data and the improved method. The accuracy of the LST derivation increased by about 1°C compared to the traditional method. The high LST areas increased and extended from the downtown to suburban area each year, but the rate of change decreased. The UHI is dramatically impacted by the rivers. There is a good relationship between the urban sprawl and the UHI. The LST was reduced by about 1°C within a 300m distance from large urban fringe green spaces. The urban landscape parks had a strong effect relieving the UHI at a 100m distance. The LST was reduced by about 0.5°C. The study greatly improves the accuracy of LST derivation, and provides a reliable parameters for the UHI researched in mountainous city.

Patients who have contraindications to the prescription of GCs (glucocorticosteroids), or have developed serious side effects during treatment with GCs, as well as patients with resistance to GCs therapy, are prescribed immunosuppressants.

The aim of the research - to study the efficacy of leflunomide monotherapy in patients with pulmonary sarcoidosis with contraindications to prescription or serious side effects of glucocorticosteroids.

Fourteen patients with sarcoidosis of the respiratory system of stage II were examined – 12 women and 2 men aged 30 to 69 years. In 10 patients there were contraindications to the appointment of GCs (diabetes mellitus – 5, hypertension – 3, obesity – 1, exacerbation of gastric ulcer – 1), which caused the appointment of immunosuppressive therapy as a starting. In 4 cases, serious side effects of SCs were noted, requiring the drug to be abolished (osteoporosis – 3, steroid diabetes – 1). Leflunomide was administered at a dose of 20 mg per day, daily for 3 months. The evaluation of efficacy was carried out using computed tomography of the thoracic cavity organs, body plethysmography, spirometry and determination of the diffusivity of the lungs.

Monotherapy with leflunomide in patients with contraindications to prescription or serious side effects of GCs was successful in 7 out of 13 patients, in 2 patients there was a stabilization of the process, in 4 patients with leflunomide therapy progression of the disease was noted and in 1 case the treatment was discontinued due to serious side effects of preparation.

The results obtained make it possible to recommend the use of leflunomide as monotherapy in patients with pulmonary sarcoidosis with contraindications to the prescription and/or poor tolerability of GCs and methotrexate. It is necessary to continue studying the possibilities of combined use of leflunomide with other drugs of the first line.

Published: May 2018

The problem of iodine deficiency diseases (IDD) is recognized as relevant due to the significant prevalence of iodine deficiency among the population of many countries of the world, an increase in the incidence of diseases with a wide range of clinical manifestations and a marked tendency to increase the frequency and severity of IDD among children of all age groups

We carried out a clinical-anamnestic examination of the child's contingent (187 persons) aged 13–17 years living in an ecologically dependent biogeochemical endemic zone of iodine deficiency, the mountain region of the Zakarpattya region during the period from 2014 to 2015. To identify the pathology of the thyroid gland, a palpatory method of examination was used according to the methodology of the WHO / MRKIDZ, 2001. According to our data 80 pupils (42.8 %) had increased thyroid gland of 1 degree, they were allocated for further and detailed examination and identification of environmentally caused somatic effects. Preventive measures included taking the dietary supplement Yosen, the manufacturer of TOV “OmniFarm”, TU U 10.8-35758392-004: 2014 for 6 months. A statistical model for forecasting the dynamics of TSH with supplements with iodine and selenium has been developed. According to our data, the degree of positive changes (decrease of TSH, increase of T4) with supplements with iodine and selenium depends on the starting content of the microelement of iodine in plasma and / or urine: the lower is the initial level of iodine - the more pronounced is the effect of supplements.

Published: May 2018

This article considers the formation of vertically integrated agrarian enterprises of the corporative type. It was determined, that enterprises with foreign investments are characterized by the high productive, financial or innovative potential, continuousness of production processes for the staged, proportional development of structural links. The management of integrative transactions is realized by principles of adaptability of the management system to exogenous factors and provides the search for new organizational, structural-functional forms, approaches to organizing their management. The principle of voluntariness of integrative relations in the system of the common agrarian policy is coordinated with the principle of one-directionality of intra-corporative and partial interests of subjects of the integrative process. At that one of main components of the mechanism of creation and functioning of enterprises with foreign investments is optimization of methods, mechanisms of concentration of property of integration subjects. Formation of the property complex of the common agrarian integrated structure is realized both by combining a functioning enterprise with agricultural, rerolling, agroservice and trade ones and by combining separate juridically independent enterprises of agriculture, rerolling industry, serving branches. Based on principles of hierarchy of relations of enterprises with foreign investments, there were separated three types of integration mechanisms. It provides the orientation of maximizing the integral result
CRITICISM OF RADICAL DIRECTIONS OF ISLAM BY REPRESENTATIVES OF ITS MODERATE STREAMS
Authors: Nesprava Mykola
Published: May 2018

The study discovers the problem of criticism and claims of representatives of moderate streams of Islam, manifestations and essence of radical forms of Salafism, especially, radical Jihadism. The new term “radical Jihadism” in developed Western countries is conditioned by its destructive and dangerous results for the society. Many European and American scientists study the question of appearance and essence of extremist streams of Islam for preventing terrorist attacks. But a position of representatives of other Islam streams is yet little-known and very important in the aspect of the deep view and study of causal connections of Jihadists’ behavior. The effective fight against manifestations of radical Jihadism is possible only if its preconditions and essence will be studied in detail. The methodology of the study is in the system analysis of results of studying the problematics by scientists, who are representatives of moderate Islam streams. Among them a sheikh Mohammad Said Ramadan al-Buti – the author of more than thirty books on questions of Muslim theology, philosophy, law and a mufti sheikh Ravil Gainutdin – a professor of Moscow Islamic university, the author of many works on Muslim theology, dogmatics and law. The result of the study is a conclusion about the exceptional censure of Islam radical streams by Muslim scientists – theologians, based on citing the Koran, historical analysis of the rise of Salafism and its followers, etymology of the word “Islam”, and also the modern interpretation of Islam for economic and geopolitical aims. Also the main conclusion is a thought that the best background of an idea of representatives of moderate streams in Islam that “Islam” is “peace” would be calming of extremists, who organize terrorist attacks in behalf of Muslims, by their own efforts.
Efficiency Measurement With A Three-Stage Hybrid Method

Published: May 2018

Data
Envelopment Analysis (DEA) is one of the most widely used efficiency
measurement techniques in the literature. In the method developed by Charnes, Cooper, and Rhodes, the relation
between input(s) and output(s) is examined and relative efficiency values are
obtained for many decision-making units. In order to be able to accurately
measure the efficiency with Data
Envelopment Analysis, the selection of input and output variables needs to be
done carefully otherwise, the results may be misleading. For this purpose, it
is aimed to make an objective selection process by using Grey Relational
Analysis (GRA) in the identification of variables in the study. Via this method
17 financial ratios of 20 firms in the BIST Food Index for the period of
2013-2015 categorized into 4 groups, then each category clustered and the
ratios which have the highest correlation within each cluster selected as representative indicator. Thus, 3 inputs and 2
output variables were selected so that the number of variables was reduced from
17 to 5.  An input-oriented BCC model was
established with selected variables to determine the efficiencies of firms in
each period. The Malmquist Total Factor Productivity Index was used to analyze
the productivity changes between periods. It was concluded that 7 firms were
efficient in each year and the productivity of the sector increased between the
periods as a result of the analysis.

Authors: Kumar Kalilasam Ranjith , Mani Venkatesan
Published: May 2018

FPGA based Quasi Z-Source Cascaded Multilevel Inverter (Quasi Zs-CMLI) using multicarrier PluseWidth Modulation (PWM) techniques are presented in this paper. Multicarrier based PWM techniques have been proposed for seven level Quasi Zs-CMLI and implemented using Field Programmable Gate Array (FPGA). For generating gating pulses to the inverter switches, Phase Disposition (PD), Inverted Phase Disposition (IPD), Phase Opposition Disposition (POD) and Alternative Phase Opposition Disposition (APOD) techniques are programmed on FPGA. In the proposed system, three solar PV emulator modules are used. These are acting as input source to the inverter. Finally, THD comparison made between different carrier based modulation with shoot through and non-shoot through the states. The proposed quasi Zs-CMLI and PWM techniques are verified through MATLAB/Simulink. For confirmation of simulation results, A laboratory prototype model have been implemented using FPGA. The capture hardware results are matched with simulation results.

Published: May 2018

The loss factor identification is the effective way to get the proper acoustic analysis in the virtual environment. Using the predictive model is a necessary part of the virtual development. The detection of the inappropriate materials or malfunction designs in the early phase of product development and can dramatically save the cost and development time. The loss factor is the nonlinear parameter for the material modeling of the noise suppression during acoustic analysis. The identification of the loss factor is necessary to perform on the real specimen. The Decay Rate Method is the effective methodology to get accurate results by using standard measuring equipment and is ideal to use in-situ environment. The article describes loss factor identification for plywood material and applications for the automotive industry for glass materials. The complete results analysis is confidential, but the overall procedure of the method is described in specimen analysis.
Intelligent identification method for whole aero-engine connection stiffness
Authors: Qu Meijiao , Chen Guo , Zhang Kaiyong
Published: May 2018

A novel intelligent identification method for determining connection stiffness values of the aircraft engine vibration model is proposed. Firstly, a dynamic finite element model of an aero-engine is established. The stiffness values of supports and mountings are taken as the connection parameters to be optimized, and then the natural frequencies of the whole machine are obtained under different connection stiffness values by finite element simulations. The regression function, which is from the stiffness to the natural frequency, is constructed in the support vector machines method. Then, the genetic algorithm is applied to a multi-objective optimization. Based on the real natural frequencies (which can be obtained by a modal test), a fitness function of multi-objective optimization of genetic algorithm is established. Using the real number coding method, the connection stiffness values of the whole machine are finally identified. An aero-engine rotor tester with casing is taken as an example to verify the method. According to the results of a modal test, the stiffness values of the supports and mountings are identified, and the results show the method effectiveness.
Non-probabilistic analysis of a double-disk rotor system with uncertain parameters
Authors: Fu Chao , Ren Xingmin , Yang Yongfeng
Published: May 2018

Vibration is a major issue in rotor systems. Due to the presence of material property dispersions, manufacture or assembling errors and time-varying working status, rotor systems are always subject to uncertainties. The uncertainties should be taken into consideration to understand the dynamic characteristics of rotors more thoroughly. In this study, interval analysis is carried out to investigate the non-probabilistic characteristics of a double-disk rotor with uncertain parameters. The uncertainties are modeled as uncertain-but-bounded variables due to insufficient essential information to define their precise probabilistic distributions. The deterministic analysis model is derived by the finite element method (FEM). The accuracy and effectiveness of the proposed method in solving uncertain rotor problems are validated by comparative study with the Monte Carlo simulation (MCS). Several cases where different physical parameters are regarded as uncertain are investigated and the dynamic response bounds are obtained. Simulations suggest that uncertainties have significant influence on the dynamic characteristics of the rotor system. Multi-source uncertainties propagation can cause heavy vibrations in mechanical systems.

Published: May 2018

Aiming at the difficulties in realizing the accurate control due to the nonlinearity of the automatic drilling system of oil drilling rig, a design scheme is proposed by giving a constant drilled-pressure to the rig for fuzzy control. Sampling error with changes in the signal was sent into the fuzzy controller, which turned the signal into a fuzzy volume. Subsequently, a precise volume was obtained accordingly and then added to an actuator for the motor control. According to the MATLAB simulation results, the response could be faster and more stable compared with the traditional control.

A novel transmission using the multistage face gears as the core component is used to realize variable speed with differential gear shifting, there are multiple face gears superimposed on the radial direction, meshing with planetary wheel at the same time, which achieves different outputs speed through braking different face gears. In order to solve the interference problems caused by asynchronous meshing motion between several face gears and the same cylinder gear, this study mainly focuses on the meshing theory study based on the double crown surfaces in tooth profile and tooth orientation. The surface structure of straight tooth and double crown are constructed according to the related surface equations, the corresponding interference conditions are obtained by comparison, every single stage face gear model is designed and assembled. This study shows that the double crown configuration surface structure can easily improve contact characteristics compared with straight tooth surface structure of face gear. In addition, the double crown configuration surface structure can improve the distribution and direction of contact path. This study is expected to establish a new tooth surface model, which can provide the best machining parameters for the face gears.

Published: May 2018

A reliable operation of generators is highly dependent on the electrical and mechanical integrity of stator end-winding vibration and has been a major concern in the last two decades. This paper focuses on the experience in hammer impact testing of end-winding vibrations of parallel phase leads and series loop caps in two hydro generators in a different temperature state. The measurements were conducted using hammer testing on the two generators separately and a discussion and comparison of the results was presented in order to perceive the dependence of the temperature and dynamic characteristics of the structures. Introductory, a brief survey of recent research progress in monitoring the end-winding vibrations in generators is presented. Subsequently, a detailed description of the performed measurement, starting from the identification of the object and conducted testing methodology according to established standards is systematically exposed. Ultimately, a paramount accent will be put on the experimental results for the measured natural frequencies of the generators, perspectives and propositions on subsequent scientific will definitely not be left out.

Authors: Panovko Grigory , Shokhin Alexander
Published: May 2018

In this work the experimental researches of dynamics of a model of a chain-type two-mass oscillatory system with two unbalance vibration exciters are carried out. The method of smooth variation of the debalances speed is used to analyze the amplitude-frequency response of the model. The modes of synchronous rotation of debalances are studied depending on the control parameter – the frequency of the supply voltage. The power characteristics of the electric drive and the influence of the carrying body oscillations on the power consumed by the exciter are established. It is shown that the effect of adaptive self-synchronization of debalances occur in the mechanical system, when the oscillation modes of carrying body vary with the excitation frequency.

Published: May 2018

The flow-induced lateral vibration phenomenon of the terminal sensitive bullets (TSB) when it is dispersed by the airborne distributor is taken as the research background. Based on the Fluent, the flow around a rotating short cylindrical TSB (L/D < 1) is simulated and analyzed varying with relative rotation velocity at high Re number (1×105 ≤ Re ≤ 3×106). The simulation results show that the flow field structure of the short cylinder with two free ends is different from the symmetry of the short cylindrical flow field with one free end, and there is no horseshoe vortex. Compared to the long cylinder with double free ends, the Cd of the short cylinder is more sensitive to the change of Re. With the increase of Re, the Cd of the short cylinder decreases, and the value is between the infinite cylinder and the sphere in the non-critical region. When the short cylinder rotates at the angular velocity ω, the top vortex bends and deforms to a ‘C’ shape on the leeward side where the fluid is accelerated. Due to the periodic disturbance of the detector, the aerodynamic coefficient of the rotating TSB is periodically vibrated. In a single cycle, the waveform of the cd shows a ‘W’ shape, and the waveform of the cl is ‘M’.

Elastic cylindrical shells interacting with a viscous incompressible fluid are widely used in various branches of science and technology, such as engineering and aviation engineering. They provide the possibility for solving a lot of problems, such as: reducing constructing weight and dimensions, equalizing dynamic influences and vibration level, as well as reducing friction and wearing, cooling. Mathematical model of the system, representing three coaxial cylindrical shells, freely supported at the ends, and interacting with viscous incompressible fluid between them under mechanical system harmonic vibration is constructed. This mathematical model represents a coupled system consisting of the Navier-Stokes, continuity for each fluid and equations and the ones of elastic coaxial cylindrical shells dynamics which are based on the Kirchhoff-Love hypotheses and the corresponding boundary conditions, namely: for the fluid non-flow and for free attaching for the shells. The constructed mathematical model allows to investigate the oscillations of a mechanical system consisting of coaxial elastic cylindrical shells interacting with viscous incompressible liquids in order to identify dangerous operating modes.

Published: May 2018

The main goal of this paper is to find stress after the dynamic loading in the spine. At the beginning, it is necessary to obtain a finite element model of the spine where the stress analysis is performed. Two geometries of pathological curvature of spine are analyzed for better understanding of stress distribution in the spine. The next step is to calculate the dynamic coefficient in analyzing the dynamic effects on the spine. Measurements of dynamic effects are done with two types of trainers. In the end the different inclinations of spine in sitting position are compared.

The paper deals with research of an engine block load caused particularly by inertia effects of the crank train rotating parts. Substantial reduction of this load can be achieved by an appropriate design of the crankshaft counterweights. The relation between crank train internal moments of rotating parts and the engine block load is investigated in the case of an I4 MPI engine with two variants of the crank train design. Used methodology is based on MBS simulations, where modally reduced flexible bodies and computational model of a hydrodynamic bearing are included.
Piston secondary motion measurement by laser displacement sensors
Authors: Dlugoš Jozef , Novotný Pavel
Published: May 2018

Measurement of the piston group behavior is still a challenge. Achieved accuracy and complexity go hand in hand with the financial requirements. This paper presents an unconventional measurement of the piston secondary motion using laser displacement sensors. Two sensors help capture the piston tilt angle, while the third sensor is used for the piston lateral motion measurement. These sensors are aimed at the piston crown. The passage between the laser source and the target spot has to be transparent. Therefore, side-valve internal combustion engine is employed. It enables the cylinder head to be made of the transparent material such as cast plexiglass. In the initial stage, the experimental engine is motored during the measurement. As for the measurement of the piston tilt angle, the results are within the physical limits. However, the same does not apply for the piston lateral results, where the measured values are too high, so the piston would penetrate the liner.

Parameter effecting the experimental determination of modal properties
Authors: Rehak Kamil , Kucera Pavel , Prokop Ales
Published: May 2018

The investigation of structure dynamic behavior can be done by finding modal properties, which are based on the relation of force and vibration response. The information about exact force value is in most application unknown, but the investigation can be done for unit magnitude of force. In case of using modal exciter, the force applied to structure is transferred by connection between modal exciter and structure. The stiffness of connection part can affect the dynamic behavior and change the modal properties, or response of investigated part, because of additional modal properties of connection part. This article is focused on the influence of two different rod stiffness during modal properties identification. The modal exciter is used to find potential critical frequency during decreasing frequency. The affect is evaluated on the surface normal velocity as well as acoustic pressure. The stiffness of rod significantly affects the dynamic response of structure and based on that can add frequency, when the emitted noise is high.
