‘Figures (2015) – mass sculptural durational performance’
Authors: Crow Liz
Published: October 2017

UK-based art-activist Liz Crow discusses the challenges of making socially engaged, political art and performance in a climate of austerity. She reflects on the euphoric moment of the 2012 Paralympics Games, and the contradictory experiences that resulted for people with disabilities who were simultaneously lauded as ‘superhumans’ and castigated as ‘scroungers’. Crow talks about the dialogic works she created to counter these unattainable – and implicitly discriminatory – categories including two durational works, Bedding Out (2012–2013) and Figures (2015). Figures, a mass sculptural durational performance, testifies to the far-reaching effects of austerity measures and also holds the potential of serving as an alternative ‘legacy’ archive of the London Summer Games. A foldout of selected images and text from the Figures project is printed in Part 4: ‘Suspending Freedom, Sustaining Spectacle’ of this special issue.

Authors: Silva Antônio Carlos Alves da , Lavor Anna Ariane Araújo de , Ribeiro Mariana Emídio Oliveira , Barden Júlia Elisabete
Published: October 2017

O presente trabalho analisa reportagens sobre a vulnerabilidade da população do distrito de Lima Campos, do município de Icó-CE, devido à escassez de água na região, ocasionada pelas secas. O procedimento metodológico utilizado foi a pesquisa bibliográfica, afim de fazer uma abordagem qualitativa do problema. A água do açude local foi utilizada para abastecer outros treze municípios que se encontravam em situação de falta de água. O posicionamento da população muda a medida que o quadro das secas se agrava, pois, o risco da indisponibilidade de água deixou os habitantes do distrito vulneráveis a diversas privações, gerando conflitos entre as comunidades. A situação é resultado da deficiência de planejamento público no enfrentamento da crise hídrica e tal situação torna a população local ainda mais frágil frente aos efeitos da estiagem.

Authors: Raimundo João Nelson , Correia Neto José Da Silva
Published: October 2017

Os estudos sobre a motivação humana no ambiente de trabalho remontam ao início dos estudos organizacionais, sejam eles em organizações públicas ou privadas. Neste sentido o presente estudo versa sobre motivação em um tipo de instituição pública, o Exército Brasileiro, tendo em vista que a desmotivação de profissionais desse tipo de instituição pode ensejar na perda de investimentos feitos ao longo de anos. Num estudo de caso no 9º Grupo de Artilharia de Campanha – MS estudamos a categoria de sargentos, numa pesquisa qualitativa onde via grupo focal buscamos identificar o que motiva essa categoria e ainda sugerir ações para diminuir a evasão. Os resultados apontaram que estabilidade, transferências, valorização do militar perante a sociedade civil, missões no exterior, por exemplo, são grandes motivadores, mas a questões salariais e do plano de carreira desmotivam. Também foram apontadas sugestões de melhoria.

Published: October 2017

The per capita consumption of flowers in Brazil has presented successive growth rates, although the consumption in consumer class called elderly, that is 60 years old or more, is still incipient when compared to other countries such as the United States, Japan and the most part of European countries where the consumption of these people is more than the double of consumption in Brazil. In this context, it is presented the results of the profile and consumer behavior evaluation of elderly flowers consumer, aiming to subsidize the establishment of marketing actions for the retail segment of the flower production chain. The study was accomplished using 169 interviews with elderly people of both genres at the time that they were buying flowers in 22 flower shops in Paraná Coast. The female gender was identified as the majority consumer (p=78.7%). It was observed a tendency in the increase of consumption based on advanced schooling. It was registered an average of acquisition of 5,81 times per year, with preferential consumption of roses, violets and orchids. The accessibility to stores, the service quality followed by the high prices of flowers, were the main consumption limiting factors in the class evaluated.
Plant derived antimicrobial peptide Ib-AMP1 as a potential alternative drug candidate for Staphylococcus aureus toxins
Authors: Ojha S. , Deep S. , Kundu S.
Published: October 2017

Due to an increase in the occurrence of multi drug resistant microorganisms a need for the development of alternative drugs comes in light. This alternative drug should be such that the microorganisms should not be able to develop resistance against them easily. Antimicrobial peptides are the most potential candidates to be developed as alternative drug. In the present study the three toxins ETA, ETB and PVL of Staphylococcus aureus were docked with four antimicrobial peptides, Ib-AMP1, JCPep7, Snakin2, Sesquin, derived from plants. The docking studies predict that Ib-AMP1 shows significant interactions with all these three toxins. Hence, further studies can be carried out for developing Ib-AMP1 as an alternative drug against the toxins of Staphylococcus aureus.
Hearing Loss in the Newborn Infant: Early Hearing Detection and Intervention
Authors: McGrath Andrew P. , Vohr Betty R.
Published: October 2017

Significant advances in health care have occurred since the 1980s and currently more than 97% of newborns in the United States undergo hearing screening, resulting in earlier identification, intervention, and improved outcomes. (1) Current technology, however, does not identify all hearing loss including mild, late onset, and progressive hearing loss. Therefore, although the rate of hearing loss at birth is approximately 1 to 2 per 1,000, it approaches 5 per 1,000 by early school age. This supports the need for continued surveillance of language milestones and hearing skills in the medical home. Types of permanent hearing loss include sensorineural, conductive, and auditory neuropathy, which occurs most commonly in NICU graduates. Multidisciplinary care is needed to ensure early access to language. Both early intervention and early amplification, no later than 6 months of age, are critical components of the formula for success.

Abstract:

The aim of this comprehensive article is to provide guidelines for the daily treatment of patients with epidermolysis bullosa, thus contributing to the attainment of their higher quality of life through the improvement of their oral health. Moreover, it is our intention to facilitate the cooperation among Hungarian general practitioners, dermatologists and dentists. Relying on recent research findings of the international literature, we intend to help general practitioners or dermatologists treating epidermolysis bullosa patients on a daily basis by identifying symptoms that require consulting an oral professional on the one hand, and to present the most important prevention strategies and further treatments advised for dentists on the other. Focusing on various aspects of dental treatment, we specify how a dentist can treat the patient without causing additional wounds or pain, and what kinds of therapy are justified by this approach.

A review on the seismic behaviour of irregular bridges
Authors: Akbari Reza , Maalek Shahrokh
Published: October 2017

This paper presents an up-to-date state-of-the-art review on the behaviour of irregular bridges under seismic excitation. Although several characteristics and definitions may be applicable to the regularity of bridge structures, almost all the published literature referencing the term ‘irregular bridge’ focuses on a specific class of straight reinforced concrete (RC) bridge with unequal pier heights as the main source of irregularity along the bridge length. Several successive as well as interrupted research works on the subject have been reported during the last two decades. Among significant developments under continuous progress in this field, two main advancements can be recognised: (a) the development of displacement-based design methodology; (b) further understanding of the higher modes effects, which reflects the adequacy of different analysis methods for irregular bridges. However, a review of the literature reveals that works being actively conducted on this subject are still inadequate and hence deserve further attention in future research to gain a better awareness of the seismic performance of irregular bridges, in order to provide simply applicable and more definitive guidelines for actual design purposes.

Literatura e pintura abstrata: Água viva de Clarice Lispector
Authors: Oliveira Solange Ribeiro de
Published: October 2017

O ensaio discute as relações intermidiáticas entre a arte e Água viva, de Clarice Lispector, concluindo pela análise do romance como uma versão literária da pintura abstrata. Descartando referências à realidade ficcional, Água viva elimina quase totalmente narrador, enredo e personagens. Entretanto, preserva resquícios desses elementos do romance tradicional, sinalizando a opção pela abstração a partir da figuração, com remanescentes de formas reconhecíveis de objetos e seres vivos ou imaginários, como em certos quadros de Wassily Kandinsky e de Manabu Mabe. Entretanto, tal como a pintura abstrata, o romance não prescinde de uma organização formal, constituída pelo emprego de imagens recorrentes, sobretudo associadas a elementos aquáticos e a construções sinestésicas. No conjunto, essas estratégias convergem para a retomada da temática existencial constante na obra de Clarice: a busca do it, do neutro, da coisa em si, embuçada sob o véu das aparências.

Published: October 2017

Background: Drug utilization studies play crucial role in the health sector and ultimately it provides insight into the efficiency of drug use and results of such research can be used to help to set priorities for the rational use of medicines and allocation of health care budgets. Respiratory tract infections (RTIs) contributing to significant mortality and morbidity of populations especially in developing countries like India. Polypharmacy and irrational prescription are significant negative fallouts in treatment of RTIs. Keeping in view of this, our study was undertaken to analyze the drug utilization pattern of RTIs.Methods: The study was conducted at Gandhi Hospital, after obtaining permission from the Institutional Ethics Committee. We have collected data of 600 case records of the patients diagnosed with respiratory tract infection and evaluated for prescribing patterns in consonance with WHO indicators.Results: Out of the total case records 348 (58%) were of male patients and 252 (42%) of female patients. Age wise distribution was done; 79 (13.16%) 0-15 years, 46 (7.67%) 16-30 years, 123 (20.50%) 31-45 years, 194 (32.33%) 46-60 years and 158 (26.33%) patients belongs to >60 years of age group respectively. A total of 4682 drugs were prescribed, 2468 (52.71%) antibiotics, 768 (16.4%) bronchodilators, 581 (12.4%) corticosteroids, 323 (6.89%) antacids, 542 (11.57%) in miscellaneous category respectively. With regard to formulations 2463 (52.60%) oral, 1463 (31.24%) injectable and 756 (16.14%) inhalational drugs were prescribed. Numbers of Fixed dose combinations were 712 (15.20%). 7.8 drugs were prescribed per prescription. 2493 (53.24%) drugs were prescribed from National Essential Medicine List. 4168 (89.02%) drugs were prescribed by their brand names.Conclusions: Prescription of drugs with branded names, Irrational prescribing, poly pharmacy were observed in our study.

Correlation between maternal serum biochemical markers with karyotyping for prenatal screening of foetal chromosomal abnormalities
Authors: Kulkarni Ketki S. , Lakhani Payal , Dalvi Sujata A. , Gupta Chandrashankar
Published: October 2017

Background: Prenatal screening for chromosomal abnormalities can be done by biochemical screening tests like dual marker test (DMT), triple marker test (TMT) and quadruple marker test (QMT). It is important to identify ideal screening test among them which best correlates with result of karyotyping which is confirmatory test of foetal chromosomal abnormalities. This helps to decrease need for invasive prenatal tests for foetal karyotyping. This study aims to evaluate sensitivity, specificity, diagnostic accuracy and correlation of DMT, TMT, and QMT with results of karyotyping.Methods: Retrospective observational study was conducted in tertiary care maternity hospital over one year- 1st January 2015 to 31st December 2015. Women with singleton pregnancy undergoing DMT, TMT or QMT were included.Results: Of the 529 women screened by biochemical marker tests, 462 (87.33%) were screen negative and 67 (12.66%) women were screen positive. In 56 women, it was false positive (83.58%) and in 11 women true positive (16.41%). In 461 women the test results were true negative (99.78%), but in one case, result was false negative (0.21%).  3/11 (27.27%)women with foetal chromosomal abnormalities were primigravidae. 4/11 (36.36%)women were below 35 years. DMT and QMT had higher sensitivity (both 100%) and specificity (90.00% and 93.18% respectively) than TMT (sensitivity 80% and specificity 82.61%). Positive likelihood ratio (LR+) was 1.00 in DMT. Diagnostic odds ratio was highest with DMT (DOR=115.11) and best correlated with karyotyping results (coefficient of correlation 0.4).Conclusions: Universal screening of antenatal women, irrespective of their age and parity is suggested. DMT has highest diagnostic value and best correlation with the results of karyotyping. Hence the dual marker test can be considered to be better test for screening for aneuploidy.
GESTÃO POR COMPETÊNCIAS: RETÓRICA ORGANIZACIONAL OU PRÁTICA DA GESTÃO DE PESSOAS?
Authors: Vieira Almir Martins , Filenga Douglas
Published: October 2017

A afirmação de que as pessoas representam o principal ativo das organizações é algo relativamente comum na literatura sobre teorias organizacionais. Mas como, na prática, valorizar esse recurso sem onerar a folha de pagamento? Como conciliar as recompensas extrínsecas com as intrínsecas? É preciso que as práticas de recursos humanos estejam alinhadas às estratégias organizacionais, ou seja, é mister incorporar a competência ao modelo de gestão de pessoas. Este ensaio teórico debate o tema para identificar as aplicações do conceito de competência, bem como as duas dimensões em que esse termo pode ser analisado: individuais e organizacionais, abordando inclusive em que medida essas duas dimensões se relacionam. São tratados três processos propostos por Dutra (2008): movimentação, por meio das práticas de captação ou seleção; desenvolvimento, analisando as práticas de capacitação e desempenho ou treinamento e desenvolvimento e avaliação de desempenho; e, valorização, por meio das práticas de remuneração fixa.
The Use of Cone‐Beam Computed Tomography in Management of Patients Requiring Dental Implants: An American Academy of Periodontology Best Evidence Review
Authors: Rios Hector F. , Borgnakke Wenche S. , Benavides Erika
Published: October 2017

Background: Application of cone‐beam computed tomography (CBCT) has grown exponentially across dentistry with a clear impact in implant dentistry. This review aims at providing the scientific context to understand if CBCT imaging should become the standard of care for patients requiring dental implants.

Methods: A literature search for CBCT applications in implant dentistry was performed using the PubMed database that included studies published between January 1, 2000, and June 24, 2017.

Results: Of 559 citations identified and manually screened, 161 were selected as suitable for the purpose of the review. The selected studies belonged to three distinct categories: 1) diagnosis and treatment outcome assessment, 2) implant treatment planning, and 3) anatomic characterization.

Conclusions: The current available literature reflects an increased optimization of emerging CBCT imaging protocols and further highlights its diverse applications for dental implant therapy. This technology continues to be considered an advanced point‐of‐care imaging modality and should be used selectively as an adjunct to two‐dimensional dental radiography. As with other ionizing radiation imaging modalities, CBCT imaging should be used only when the potential benefits to the patient outweigh the risks. Dental health care professionals should consider CBCT imaging only when they expect the diagnostic information yielded will lead to better patient care, enhanced patient safety, and ultimately facilitate a more predictable, optimal treatment outcome.

Published: October 2017

Background: Besides a wholesome food, honey is known for its therapeutic implications. We investigated the antifungal

activity of five honeys of different types from Pakistan against various pathogenic fungal strains. Antifungal properties of

processed and non-processed honey were determined.

Materials and Methods: The antifungal assay of honey was carried out against Aspergillus niger, Aspergillus flavus,

Aspergillus fumigates, Alterneria alternata, Fusarium solanai, Microsporum canis, Penicillium funiculosium and Rhizopus

solanai. Different dilutions of honey samples were used (20%, 50%, 70%, 90% and 100% w/v so as to find out the

minimum effective concentration of each honey type.

Results: It was observed that all of the honey samples were highly active, with percent inhibition range of (3-81%) for

Aspergillus niger, (2-82%) for Aspergillus flavus, (1-76%) for Aspergillus fumigates, (1-84%) for Alterneria alternata, (2-

67%) for Fusarium solanai, (1-87%) Microsporum canis, (2-78%) Penicillium funiculosium and (1-86%) for Rhizopus

solanai.

Conclusion: The study of Pakistani honey brands reveals that they possess a substantial antifungal nature. Therefore, they

may be used in curing fungal infections along with antifungal drugs as a cheaper alternative natural remedy with no side

effects.
Performance Prediction for Advanced Well Structures in Unconventional Oil and Gas Reservoirs Using Artificial Intelligent Expert Systems
Authors: Enyioha Chukwuka , Ertekin Turgay
Published: October 2017

Advanced well structures have continued to see an increase in field applications, particularly in unconventional reservoir development. Traditional methods for well performance analyses barely capture the complex interactions between these well structures and the reservoir. In this study, a set of artificial expert systems has been developed to predict the performance of advanced well structures in tight oil reservoirs given a set of reservoir properties.

The artificial expert systems are built on a system of neural networks. Data for training and validation was generated by building feature sets that contain inputs that were randomly selected within a broad range of limits to capture properties of a typical tight oil reservoir. The features set for inputs into the neural networks includes reservoir extent data, rock and fluid properties, relative permeability and capillary pressure data, as well as well design and operating condition data. Each feature set is run through a commercial numerical simulator to provide time-series data of cumulative oil, gas, water production, as well as bottom-hole pressure profile where applicable. Both the feature set and the time- series data are used for training the neural networks.

Generalization tests conducted on each expert system using a validation dataset show that the outputs of the expert systems compare closely with results from the numerical simulator for the same dataset with an average Mean Absolute Error (MAE) of 8%. Other tests such as permutation tests for estimating feature importance, and sensitivity analysis were conducted. The results of the sensitivity analysis showed that the expert system is consistent within its own parametric domain. It also showed that a trained expert system has the ability to diagnose certain characteristics of flow patterns within the reservoir, particularly in the near-wellbore region. This is determined by observing the relative sensitivity of one feature to another.

This study shows that an artificial expert system, once trained properly, provides a very practical, fast and robust method for predicting production performance in tight oil reservoirs using advanced well structures. This helps to eliminate the snag of developing an in-depth mathematical model to describe the complex relationships between variables involved, and also increases efficiency in well planning by providing quick, accurate estimates for production forecasts, thus reducing the iteration time spent between the reservoir engineer and other disciplines.
Dynamic Data Analysis with New Automated Workflows for Enhanced Formation Evaluation
Authors: Proett M. A. , Ma S. M. , Al-Musharfi N. M. , Berkane M.
Published: October 2017

Petrophysical workflows are primarily designed to process static data for traditional openhole logs (i.e., triple & quad combo) which can provide estimates of porosity, saturation, lithology and mineralogy. Dynamic data from core analysis can help to extend the log analysis for estimates of the rock’s dynamic properties such as permeability. However, there is normally a high degree of uncertainty in these estimates and formation testing and sampling (FTS) data is often required for reservoir condition calibration. The workflow for analyzing FTS data is highly specialized, and normally not performed by an operating petrophysicist, but by a specialist whose expertise covers FTS tools and applications, openhole logs, and reservoir dynamics.

This paper bridges the gap between operational petrophysicists and FTS specialists by documenting standardized methods of FTS measurements and introducing an automated workflow for petrophysicists to conduct FTS jobs. This workflow begins with job planning, to data processing, decision making and recommendations. Unique characteristics and capabilities of this workflow are summarized below.

The job planning methodologies are based on fundamental principles to determine how different tool technologies will perform in specific reservoir conditions. It will ensure that the most optimized selection of tools and modules are made for FTS operations. Measurement uncertainties and data qualification criteria are critical parts of the workflow. Expected uncertainties are compared to measured uncertainties to assess the results’ reliability. With test uncertainties, error bars are established for each measurement which are then incorporated into data processing such as gradient estimates. A quality grading algorithm is used to objectively provide a rating for each test based on the measurements. Exceptions for test anomalies are also handled and interpreted automatically. In real-time testing operations, automatic methods for objectively quantifying data quality and uncertainty are used for pressure, mobility, and fluid gradient analyses. Real-time decisions can then be made to either adjust pressure points or take fluid samples at critical locations to reduce uncertainty.

Preliminary results of applying this workflow to automatically process test data and determine data quality more objectively, consistently, and efficiently are demonstrated using field examples.
Elemental Compositional Zoning Using Reservoir Formation Water Samples for Oilfield Applications
Authors: Jimoh I. A. , Søgaard E. G. , Muff J. , Kano M. Yahaya
Published: October 2017

Formation water samples from 170 wells in Viola Limestone Formation in Kansas were analyzed based on multi elemental relationships on a field scale along 4733 ft. depth interval. Results indicated that physico-chemical parameters such as pH, total dissolved solid (TDS), specific gravity and resistivity showed a varying functional behavior with depth. In addition, the Na+, Ca2+, Mg2+, Cl–, SO42− and HCO3– ions predominate in the formation water samples from different wells. The relationships between the chemical compositions of formation waters showed that the concentrations of most dissolved constituents correlated positively with chloride ions with the exception of SO42− HCO3– and pH that correlated negatively. The model output of the self-organized map classification of Ca2+, TDS, HCO3–, SO42−, temperature and pH resulted in five classification groups from the formation water samples using a linear transformation. The relative frequency of the groups in the model were 18.53% for zone 1, 24.71 % for zone 2, 31.27 % for zone 3, 17.37 % for zone 4 and 8.11% for zone 5. The elemental correlation to the model of the principal components was 0.85 for pH, 0.80 for Ca2+, 0.75 for Temp, 0.74 for TDS, 0.67 for SO42− and 0.53 for HCO3– respectively. Based on these results, we were able to predict carbonate scale tendency of each group using Langelier method of saturation index and to interpolate the scale formation tendency of each classification group with depth.

Currently, researches on the acoustic radiation efficiency and sound insulation performance of the micro-perforated plate mainly focused on the experimental test, and the numerical simulation is rarely reported. In this paper, firstly, the discrete element method was applied to test the acoustic radiation efficiency of the micro-perforated plate. It was shown that the experimental result was reliable, which made up for the deficiency of the traditional vibro-acoustic test method. Secondly, the pulse decay method was used to test the damping loss factor of the perforated plate. Then, the transfer admittance on both sides of the micro-perforated plate was computed to simulate the properties of the hole. Finally, the damping loss factor and admittance were imported into the boundary element model (BEM) of the micro-perforated plate, in order to compute the transmission loss, and it was compared with that of the experimental test. As shown from the compared result, the sound insulation performance of the micro-perforated plate can be predicted effectively using this method. Based on the verified simulation model, the impact of the hole diameter, plate thickness and perforation rate on sound insulation performance of the perforated plate was studied. However, each structural parameter of the perforated plate can't be optimal through the above analysis. As a result, an optimization design was conducted on it based on the improved genetic algorithm. Finally, the perforated plate which had the optimal structural parameter and performance was obtained. Finally, the optimized perforated plate was applied on the high-speed train, and the experimental results showed that the interior noise in the high-speed train was reduced obviously.

Published: October 2017

The vibration and noise of brakes have always been prevalent and difficult problems in the automobile industry and its related academic circle. The current study mainly focuses on the groan of the drum brake with a foldable cam lever actuation device strainer. The groan of the limit cycle generated by friction reappears after building its model in the ADAMS. Accordingly, a rigid flexible coupling model with a multi-layer friction plate is built. A simulation analysis shows that the model exhibits good braking stability and can reduce the amplitude of a brake groan through a comparison of the vibration characteristics of the drum brake and foldable cam lever with a conventional cam. A virtual prototyping analysis method for the dynamics characteristics of the foldable cam lever brake is also presented.
Numerical optimization and analysis on vibration characteristics of bicycles based on the novel CA-PSO algorithm
Authors: Zhang Jin , Gao Jiang Hua , Wu Jian Guo
Published: October 2017

Regarding the published researches on bicycles, they fail to design fatigue characteristics of the bicycle. In addition, dynamics and fatigue characteristics are not further improved by using advanced optimization algorithms. Aiming at these questions, this paper tries to optimize dynamics and fatigue characteristics of the bicycle through combining finite element model with advanced algorithms. The advanced algorithm applies ideas of cellular automation (CA) to Particle Swarm Optimization (PSO), and then a hybrid CA-PSO algorithm is proposed. Moreover, the finite element model is also validated by experimental test. Computational results show that: the maximum stress of bicycles is mainly distributed on the frame, especially on joints of different round pipes at different moments mainly because a dead corner is at the joint, and the dead corner can easily cause stress concentration. Under alternating forces, the stress concentration at joints will cause fatigue damage. Therefore, the service life of this position will be the shortest. As a result, the dynamics and fatigue characteristics of the joint position are taken as the optimized objective. In order to verify the optimized effectiveness of the proposed CA-PSO algorithm in the paper, the widely used PSO algorithm and PSO-GA algorithm are also used to optimize the bicycle. When the traditional PSO algorithm is used to optimize the bicycle, the root-mean-square value and maximum difference of vibration accelerations are decreased by 11.9 % and 14.3 %. When the PSO-GA algorithm is used to optimize the bicycle, the root-mean-square value and maximum difference of vibration accelerations are decreased by 20.3 % and 12.9 %. When the proposed CA-PSO algorithm is used to optimize the bicycle, the root-mean-square value and maximum difference of vibration accelerations are decreased by 27.1 % and 18.6 %. Compared with other two kinds of PSO algorithms, optimized effects of vibration accelerations are very obvious. In addition, the fatigue life of the original structure is 5 years, while the fatigue life of the optimized bicycle is 7 years. Therefore, the fatigue life is improved obviously.
Real-time dynamic substructure testing of soil-adjacent structure system based on branch mode method
Authors: He Tao , Jiang Nan
Published: October 2017

The concept of inertia coupling terms among substructures was proposed. Based on the branch mode method, the superstructures and foundation soil of one soil-adjacent structure system were divided into different branches. The branch mode method was effectively introduced to real-time dynamic substructure testing (RTDST) by decomposing and transforming the motion equation of the entire system. It was also applied for the interaction coupling terms to exchange data between the physical and numerical substructures. This method decreased the degree-of-freedom of the linear substructure effectively and considered the effects of foundation translation and rotation on the upper structures. One system composed of two adjacent four-story steel structures (S1 and S2, respectively) and foundation soil was presented in this study. S1 was applied on a shaking table as the physical substructure, whereas the foundation soil and S2 were set as two numerical substructures and simulated in a computer. The seismic response of the entire coupling system was analyzed by real-time data exchange among substructures. Test results agree with numerical solutions. The RTDST based on the branch mode method is a feasible and reliable method for the investigation of soil-adjacent structure interaction (SASI) problems, and provides a new way to consider SASI problems in the RTDST.

This paper introduces a novel tumbleweed rover design that employs a pipe-type energy harvester system to harvest electrical power from the wind indirectly. The critical parameters law of electromagnetic induction is studied firstly and then propose a preliminary model of the layout of harvesters. Simulates the motion of the harvester inside a spherical shell to achieve the performance of voltage generation and summarize the varying rules of induced voltage. Given the effect of centrifugal force, we further propose spring as a solution to support magnet to recover reciprocating motion in harvester. Finally, the experiments are implemented based on the simulated model to verify the dependability of the energy harvester and the validity of induced voltages’ varying rules.

В системах управления современных роботов используется нечеткая логика, поэтому целесообразно подавать команды управления роботом на основе нечеткой логики, которая позволит роботам эффективно выполнять поставленные задачи. В статье рассматривается управление транспортным роботом голосовыми командами и моделирование его движения в программном продукте Microsoft Robotics Developer Studio. Для моделирование движения транспортного робота использовался язык Visual Programming Language (VPL) - среда визуального программирования для создания и отладки приложений. Для распознавания голосовых команд используется планшетный компьютер или мобильный телефон с операционной системы Android с приложением, при помощи которого можно управлять роботом с использованием интерфейса Bluetooth. Разработана программа, которая позволит человеку управлять роботом с помощью речи. Получена визуальная программа управления движением транспортного робота. Приведен пример моделирования робота и его траектория движения с использованием голосового управления. Разработанная система управления позволяет следовать транспортному роботу от одной целевой точки к другой с использованием голосового управления. Задача управления роботом с использованием голосового управления существенно упрощается, поскольку она практически не требует специальных навыков от оператора. В конечном счете, голосовое управление облегчит использование роботов в промышленности, быту и других областях. Управлять можно будет не только роботами, но и другими устройствами, имеющими микропроцессорное управление.
