Authors: Jeon Seokhee , Lee Hongchae , Jung Jiyoung , Kim Jin Ryong
Published: October 2018

This study focuses on design of user-adaptive tactile keyboard on mobile device. We are particularly interested in its feasibility of user-adaptive keyboard in mobile environment. Study 1 investigates how tactile feedback intensity of the virtual keyboard in mobile devices affects typing speed and user preference. We report how different levels of feedback intensity affect user preferences in terms of typing speed and accuracy in different user groups with different typing performance. Study 2 investigates different tactile feedback modes (i.e., whether feedback intensity is linearly increased, linearly decreased, or constant from the centroid of the key, and whether tactile feedback is delivered when a key is pressed, released, or both pressed and released). We finally design and implement user-adaptive tactile keyboards on mobile device to explore the design space of our keyboards. We close by discussing the benefits of our design along with its future work.

Failure to achieve pathologic complete response is associated with poor prognosis in breast cancer patients following neoadjuvant chemotherapy (NACT). However, prognostic biomarkers for clinical outcome are unclear in this patient population. Cyclin-dependent kinase 9 (CDK9) is often dysregulated in breast cancer, and its deficiency results in genomic instability. We reviewed the records of 84 breast cancer patients from Emory University’s Winship Cancer Institute who had undergone surgical resection after NACT and had tissue available for tissue microarray analysis (TMA). Data recorded included disease presentation, treatment, pathologic response, overall survival (OS), locoregional recurrence free survival (LRRFS), distant-failure free survival (DFFS), recurrence-free survival (RFS), and event-free survival (EFS). Immunohistochemistry was performed on patient samples to determine CDK9 expression levels after NACT. Protein expression was linked with clinical data to determine significance. In a Cox proportional hazards model, using a time-dependent covariate to evaluate the risk of death between groups beyond 3 years, high CDK9 expression was significantly associated with an increase in OS (HR: 0.26, 95% CI: 0.07-0.98, p=0.046). However, Kaplan-Meier curves for OS, LRRFS, DFFS, RFS, and EFS did not reach statistical significance. The results of this study indicate that CDK9 may have a potential role as a prognostic biomarker in patients with breast cancer following NACT. However, further validation studies with increased sample sizes are needed to help elucidate the prognostic role for CDK9 in the management of these patients.
Conservative Management of Abnormally Invasive Placenta Previa after Midtrimester Foetal Demise
Authors: MacGibbon A. , Ius Y. M.
Published: October 2018

We present the case of a midtrimester intrauterine foetal demise (IUFD) in the context of abnormally invasive placentation. This was a grade 4 placenta previa with placenta increta in a patient requesting fertility conservation and was managed conservatively without immediate surgical intervention. The patient spontaneously delivered the fetus after 33 days, followed by a large obstetric haemorrhage requiring immediate laparotomy and hysterotomy. Her uterus was preserved and she went on to recover without further significant complication. While conservative management of morbidly adherent placentas has been well documented, there are no published cases of this strategy in the context of IUFD and fertility preservation.
An Experimental Investigation of the Progressive Failure of Sandstone and Its Energy Evolution Characteristics
Authors: Chen Yan , Guo Baohua
Published: October 2018

In this research study, the progressive failure and energy evolution characteristics of sandstone samples with different sizes were explored under uniaxial and triaxial compression conditions. The characteristic stresses and strains were captured using the crack axial strain levels and dissipative energy. The results showed that, with the increase in the ratios of the height to diameter (H/D), the crack closure stresses increased, while the crack damage stresses decreased. However, the levels of both the crack closure stresses and crack damages were observed to increase with the H/D. With increase in the confining pressure, it was found that the crack closure and crack damage stresses increased, while their levels decreased. The strains of the crack closures, peak crack axial, and crack propagation were observed to decrease with the H/D, while the crack closure strain levels increased. Also, the crack propagation strains were observed to increase with the confining pressures, while the crack closure, peak crack axial, and crack closure strain levels decreased. The progress failure of the sandstone samples was also obtained based on the evolution characteristics of the dissipative energy. The relationship between the energy densities during each phase and the H/D was also analyzed. It was determined that, with the increasing of the H/D, the input, elastic, and dissipative energy densities displayed different evolution characteristics. Furthermore, with the increases in the characteristic stresses, the input and elastic energy densities were found to increase. The dissipative energy density displayed a slight increase with the increases in the peak strength, which resulted in variations with regard to the crack closures and crack damage stresses.

Published: October 2018

Preoperative skin preparation plays a major role in preventing postoperative infections. This study aims to compare a single skin preparation (povidone iodine) with a double skin preparation (chlorhexidine gluconate followed by povidone iodine). Forty patients affected by proximal humeral fracture were included in the study. The day of surgery the two skin preparation strategies were performed in the same shoulder, divided into two areas, at the level of the deltopectoral approach. Skin swabs were collected from each area and subjected to microbiological analysis. Both skin preparations significantly reduced the positive culture rate. Coagulase-negative staphylococci (CoNS) dropped from 92.5% to 40% and to 7.5% after the single and double skin preparation (p<0.001), respectively. The positivity rate was reduced from 50% to 17.5% (p=0.002) and from 27.5% to 0% (p= 0.001) for Propionibacterium acnes and Staphylococcus aureus, respectively, with no difference between the two preparations. The double skin preparation had a more significant effect on bacterial load against CoNS compared to the single skin preparation (p<0.001 versus p= 0.015). In conclusion, both the approaches reduced S. aureus and P. acnes skin load, whereas the double skin preparation is more effective than the single one against CoNS. In light of our findings, preoperative strategies able to reduce bacterial load could potentially increase the final efficacy of perioperative traditional skin preparations.
Protective Ceramic Coatings for Solid Oxide Fuel Cell (SOFC) Balance‐of‐Plant Components
Authors: Winter Raymond L. , Singh Prabhakar , King Mark K. , Mahapatra Manoj K. , Sampathkumaran Uma
Published: October 2018

Solid oxide fuel cells (SOFCs) have the potential to meet the growing need for electrical power generation if the cost per megawatt can be further reduced. Currently, SOFC stacks are replaced too frequently to be cost competitive. SOFC service life can be extended by preventing chromium‐ (Cr‐) bearing species from evaporating from the interior surfaces of balance of plant (BOP) components and poisoning the cathode to increase the lifetime. We have developed yttria‐stabilized zirconia (YSZ) and aluminum oxide‐ (Al2O3‐) modified sol‐gel paints or inks for coating BOP components. 430 stainless steel (430SS) substrates with three surface conditions were coated with the 0.8–1.5 µm thick YSZ and Al2O3 paints. The coated 430SS samples were tested for thermal cycling resistance, thermal soak, and Cr evaporation. Thermal soak and thermal cycling test results show promise for the YSZ‐coated 430SS substrates. The Cr evaporation test of a coated substrate showed a 51% reduction in Cr generation, when compared with a bare substrate.

Published: October 2018

In the present study,
the relationship between economic growth and export diversification was
examined for 10 emerging market economies. For this purpose, the panel data
analysis was performed by using the data of period between 1968 and 2014. Within
the scope of this analysis, the cross-sectional dependence test and the panel
bootstrap causality test developed by Konya (2006) were implemented. According
to the results of empirical analyses, it was determined that there was a
unidirectional causality relationship from economic growth to export
diversification only in Indonesia. Moreover, it was also
found that there was a unidirectional causality relationship from export
diversification to economic growth in Argentina, Columbia, India, Malaysia, and
Turkey. However, no causality relationship was found for other countries. These
results reveal the importance of adopting the policies improving the product diversification by
promoting the manufacturers in emerging market economies.

PUTTING ‘N’ or REPLACING THE ‘S’ IN THE BRICS? NIGERIA’S RISE AS AN EMERGING POWER
Authors: HASHIRU Mohammed , TÜFEKÇİ Özgür
Published: October 2018

The economic and political strides made by Nigeria and South Africa in the 21st Century have drawn the attention of the world to them. In order to accelerate its goal of enhancing market access opportunities among other objectives to ensure growth as well as compete with G7, the club incorporated the South African state in 2010 when it realized the nation is an emerging power and could be a catalyst in pushing forward the BRIC agenda. Since investors appear to be quite attracted to states with larger prospects of growth, states who are looking out for similar states with interests to form clubs like BRICS are likely to cooperate with Nigeria as it has been projected to be suitable in the formation of clubs such as MINT -Mexico, Indonesia, Nigeria, Turkey-. We argue however that both Nigeria and South could, if brought together in BRICS, facilitate progress in achieving the aims and objectives of the club. But what informed the clubs’ decision of incorporation of South Africa? This paper will the question and give more reasons why Nigeria’s inclusion is necessary
A multi-method case study of textile craft-design applications – usability and effects on the design process
Authors: Sini Riikonen , Pirita Seitamaa-Hakkarainen
Published: October 2018

This article presents a multi-method case study of five mobile device and desktop computer applications intended specifically for craft-design. The main aim of the study was to investigate the effects of application usage on the craft-design process and to analyse the usability of the applications from three perspectives: user experience, traditional usability and functionality. Eight master’s level craft teacher students evaluated the applications and used those to conduct a design task on a Virtual Design Studio course at the University of Helsinki. To enable an authentic working environment and style for the participants and to gather research data remotely, a multi-method approach was designed that included data from questionnaires, written tasks and recordings of screen events. Analysis of the effects of application usage on the craft-design process revealed three factors that promote changes: the usability of an application, new possibilities and limitations compared to traditional design methods and the technical expertise of the designer – usability being the most significant factor behind the changes observed.
Intersecting modes of aesthetic distance and mimetic induction in therapeutic process: Examining a drama-based treatment for military-related traumatic stress
Authors: Ali Alisha , Wolfert Stephan , Lam Ingrid , Rahman Tazmin
Published: October 2018

Can Shakespeare be a treatment for posttraumatic stress in military veterans? This is the question that our research team has been examining through the empirical investigation of the DE-CRUIT program. DE-CRUIT uses Shakespeare’s verse to help veterans with the articulation, sharing and processing of trauma. In this article, we focus specifically on the therapeutic process of the program that involves various modes of aesthetic distance in combination with mimetic induction, a treatment technique in which fictionalized narrative reflects the real-life experience of trauma. After describing that process, we illustrate these various intersecting therapeutic components through the case of ‘D.’, a military veteran who took part in DE-CRUIT after many years of living with a secret, non-disclosed trauma.
Drama therapy and the invisible realm
Authors: Pendzik Susana
Published: October 2018

This article is based on the Keynote for the 38th Annual Conference of the North American Drama Therapy Association, ‘From theory to practice: The drama therapist’s toolbox’, Danvers, Massachusetts, 2017. The speech explored the notion of the ‘invisible’ in drama therapy, in dialogue with four interrelated bodies of knowledge that partake of this concept: shamanism, theatre/arts, psychotherapy and spirituality. By focusing on the invisible, a genuine tool of drama therapy, within a comparative outlook, this article positions the field within a broader perspective while simultaneously pointing out its uniqueness.
A brief history of Japanese popular culture in Japanese language education: Using ‘manga’ in the classroom
Authors: Iida Sumiko , Takeyama Yuki
Published: October 2018

This article discusses a history of Japanese popular culture (JPC) located in the broader field of Japanese language education, particularly focusing on ‘manga’. JPC has drawn the public attention of Japanese language educators following an international boom in the consumption of anime and ‘manga’ in the early 2000s. However, looking into JPC and its location in the context of Japanese language education, its history goes further back to the late 1980s and the early 1990s, when ‘manga’ and anime began to be used in classrooms. Despite active attempts using JPC in Japanese language education, research into this field was still inactive until the end of the twentieth century. This article is therefore aimed at connecting classroom practices and research into JPC over time since the late 1980s to look into how JPC in Japanese language education has been viewed and used differently in its trajectory and implies its future direction. The article first critically discusses the early days of JPC, namely ‘manga’ in Japanese language education by reviewing three periodicals of the early to the mid-1990s – Mangajin, Gekkan Nihongo and Nihongo Kyōiku Tsūshin. Second, the article overviews research into ‘manga’/anime and Japanese language education from the late 1980s to early 2010. The results of the analyses imply that the early days of JPC in Japanese language education were triggered by the struggle of the instructors finding teaching resources rather than the motivation of the learners. In contrast, a number of more recent studies of JPC in Japanese language education align with both the learners’ and the teachers’ demands and motivations of daily classroom practice.
Curating as a dialogue-based strategy in art education
Authors: Vella Raphael
Published: October 2018

Contemporary artists are increasingly engaging in curatorial work and strategies while curators interpret the exhibition as an artistic medium in its own right. The teaching of art in schools and art education programmes in universities, however, does not often integrate curating as an activity or field of study within more conventional studio classes or methodologies for teaching and learning art. After briefly outlining a history of key artist-curators, this article suggests that curating – particularly its collaborative, social qualities – can enrich art pedagogies and curricula, and proposes four curatorial processes that could positively expand the remit of art education. These processes are understood as integral aspects of art-making and focus on the development of a pedagogy of dialogue, creating dialogues between different artworks and objects, dialogues between curatorial positions, dialogues between works of art and various publics, and finally, facilitating the etymological notion of ‘care’ within the art class.
The Title I narrative: Connecting cultural and critical awareness through the arts
Authors: Herring Aimee , Hunter-Doniger Tracey
Published: October 2018

This article discusses a case study that investigated preservice generalist teachers in a visual and performing arts methods class. It was revealed that three themes reoccurred throughout this course that centred on children of low socio-economic status. These themes included reaching the Title I students, connecting through cultural awareness and critical awareness through the arts. The significance and implications of these themes demonstrate there is a need for art education methods courses to explicitly address these issues and provide avenues for preservice generalists to enhance the learning of their future students.
A new tool for developmental assessment based on the Common European Framework of Reference for Visual Literacy – an international usability study

Published: October 2018

What competences in visual literacy should students and European citizens in general master to be able to participate in contemporary society? This central question was addressed by the European Network of Visual Literacy (ENViL). This international community of experts developed a structure of sixteen subcompetences: the Common European Framework of Reference for Visual Literacy. Based on this framework, we developed a tool for self-assessment in secondary education: the visual rubrics. This tool was tested in several countries. The current article describes the evaluation of the criteria included in the tool and students’ comprehension of the tool as a self-assessment system. The consequences for improved rubrics are discussed.
Contratos de Impacto Social na rede estadual de São Paulo: Nova modalidade de parceria público-privada no Brasil
Authors: Cássio Fernando L. , Goulart Débora Cristina , Ximenes Salomão Barros
Published: October 2018

Este artigo analisa o desenvolvimento de uma nova modalidade de parceria público-privada na educação brasileira, o denominado Contrato de Impacto Social (CIS), cujo projeto-piloto, patrocinado pelo Banco Interamericano de Desenvolvimento, está em fase inicial de implementação no Estado de São Paulo. Diferentemente da filantropia tradicional, que se legitima no pretenso caráter não-lucrativo de suas ações, o CIS assume a possibilidade de obtenção de taxas de retorno com “investimentos sociais”, ensejando a criação de um novo ecossistema de finanças sociais e incorporando ao contexto da privatização da educação agentes interessados em capitalizar com a provisão de serviços públicos a populações vulneráveis—no caso em tela, a estudantes do Ensino Médio da rede estadual paulista. Esse tipo de contrato—cujo pagamento é feito mediante a “entrega” de resultados—levanta uma série de questões éticas, jurídicas e político-pedagógicas relacionadas à realização de “experimentos sociais” com estudantes em condição de vulnerabilidade. A partir da análise de documentos internos da Secretaria de Estado da Educação de São Paulo, cotejados com fontes provenientes de escolas estaduais, concluímos que, já desde o início de sua implementação, o CIS da educação paulista não apenas rompe com padrões de ética científica, mas também viola o princípio da gestão democrática escolar consagrado na Constituição Federal.
Marketing accountability e excelência na escola pública portuguesa: A construção da imagem social da escola através da performatividade académica
Authors: Torres Leonor Lima , Palhares José Augusto , Afonso Almerindo Janela
Published: October 2018

Os autores procuram refletir sobre a relação entre os resultados obtidos pelos alunos nos exames estandardizados, a excelência académica e a forma correspondente de accountability. Partimos do pressuposto de que os testes estandardizados e a excelência académica sustentam não só um managerial model of accountability mas igualmente um modelo de (quasi) market accountability em educação, que providencia estratégias de marketing escolar. Do ponto de vista metodológico, este estudo é apoiado por um trabalho de campo de longa duração desenvolvido em várias escolas públicas portuguesas, onde se analisaram documentos, observaram os rituais públicos de distinção académica e se entrevistaram diretores escolares, professores e estudantes. Os resultados mostram que os rituais públicos de distinção académica dos melhores alunos constituem uma estratégia de marketingusada para promover a imagem social da escola, essencial para induzir a escolha da escola pelas famílias e para reforçar as decisões da liderança do diretor.
Theses on Babylonian Philosophy
Authors: Van De Mieroop Marc
Published: October 2018

Through an enumeration of six theses this article argues that there was indeed a system of thought in ancient Babylonia that we can call philosophy, despite what the famous mid-twentieth century ad book Before Philosophy. The Intellectual Adventure of Ancient Man maintained. We can discover the principles of systematic thought in the numerous lists that Babylonians and other writers of cuneiform in the ancient Near East used. The key to philosophical understanding lay in the idea that writing produced a truth of its own, distinct from what was observable in physical reality.

The effects of vitamin D supplementation on healthy and hypercholesterolemic rabbits on levels of OSI and paraoxonase
Authors: Kocabaş Rahim , Aköz Mehmet
Published: October 2018

Objective

Conflicting data are available in literature regarding the effects of vitamin D (VitD) supplementation diet on lipid panel. Therefore, we had the purpose to evaluate the effects of VitD supplementation on lipid panel by a controlled experimental study, and those of VitD supplementation on oxidative stress index (OSI) and paraoxonase-1 (PON1) values in healthy and hypercholesterolemic male rabbits.

Methods

Thirty New Zealand rabbits were randomly separated into control, VD, HC+VD and HC groups. Control and VD groups were fed with standard chow, whereas HC+VD and HC groups were fed with 0.5% cholesterol chow a period of 8 weeks. During this period, VD and HC+VD groups were orally administered with 300 IU/kg/day VitD.

Results

The increase in serum total cholesterol (TC) and OSI level of HC group were significant compared to those in HC+VD group. Decreases in serum HDL-cholesterol (HDL-C) and TC levels of VD group were significant within the groups.

Conclusion

Without any doubt it is important that applied VitD level should be in the ideal range for healthy living. However, it is also necessary to increase the serum HDL-C level (and hence PON1), which is decreases as a result of VitD supplementation. Therefore, we believe that during VitD supplementation, regular physical activity should be performed to increases serum HDL-C.

A reliable method using disposable pipette extraction (DPX) based on composite of pernigraniline and styrene–divinylbenzene (Sty–DVB) copolymer was applied to the analysis of dexamethasone in synovial fluid using high-performance liquid chromatography and ultraviolet (UV) detector (HPLC–UV).

DPX variables, namely, number of draw/eject cycles for extraction or desorption, sample pH, volume, and desorption solvent, were optimized to establish the best sorption equilibrium and analysis time. The highest extraction efficiency value was obtained with 50 μL of synovial fluid mixed with 1950 μL of water, in five cycles of 300 μL of sampling, followed by liquid desorption of the drug with 300 μL of methanol in three cycles. The developed method demonstrated a linear response over the range from 10 to 100 ng/mL, with R2 = 0.993. The limit of quantification (LOQ) was 10 ng/mL. Based on the validation results, the proposed method can be a useful tool to detect dexamethasone levels in synovial fluid.

Published: October 2018

This study aimed to develop a chromatographic method to quantitatively determine phenol in fish tissues. This method involves solvent extraction of acidified samples, followed by derivatization to phenyl acetate and analysis with gas chromatography coupled with mass spectrometry (GC–MS). Phenol in a representative tissue sample (belly, gill, or renal tubules), which was homogenized with 2 N sulfuric acid, was extracted with ethyl acetate and derivatized to phenyl acetate using acetic anhydride and K2CO3 in water. An n-butyl acetate extract was injected into the GC–MS. The linearity (r2) of the calibration curve was greater than 0.996. The analytical repeatability, which is expressed as the relative standard deviation, was less than 6.14%, and the recovery was greater than 96.3%. The method detection limit and the limit of quantitation were 8.0 μg/kg and 26 μg/kg, respectively. The proposed method is also applicable to the analysis of other biological tissues for phenol and its analogs, such as pentachlorophenol.

Purpose:  The aim of this retrospective study is to evaluate the etiology clinical and laboratory features of fever of unknown origin (FUO) diagnosed in 30 pediatric patients. Materials and methods: The clinical data including the etiology, diagnostic approaches and clinical characteristics were retrospectively analysed in 30 pediatric patients with FUO who presented to our clinic in one year period. Results: The median age of the patients was 63 (6-192) months. Among the patients, 12 were male (40%), while 18 were female (60%). The median duration of the fever was 22.5 (3-60) days during hospital admission. The most common physical findings were hepatomegaly and splenomegaly, which were observed in 53. 3 and 40 patients, respectively. The cause of the FUO was detected to be infection in 14 patients (46.6%), connective tissue-vascular diseases in 8 patients (26.7%), malignancies in 5 patients (16.7%), and miscellaneous diseases in 1 patient (3.3%). In two patients (6.6%) the etiology could not be identified. Leishmaniasis, tuberculosis and brucellosis were the most commonly identified infections, whereas juvenile rheumatoid arthritis and acute lymphoblastic leukemia were the most common non-infectious causes. Conclusion: The most common cause of FUO in our study was infection diseases. Connective-vascular tissue diseases and malignancies are also important causes of FUO. In our opinion, detailed patient history, carefully physical examination and close clinical follow-up may reduce the number of the invasive procedures and non-invasive tests.

Authors: Sanhueza Sergio M. R. , Tofoli Fernando L. , Oliveira José Carlos de , Guimarães Geraldo C.
Published: October 2018

Air conditioners deserve special attention, because they represent a significant part of the power system load, mainly in high temperature regions. This work takes into account conventional air conditioners, and also variable-speed arrangements with and without undervoltage protection. The modeling of such type of load is analyzed for simulation purposes, as a novel representation of variable-speed units with undervoltage protection is introduced. The behavior of each air conditioner is verified in steady state operation considering typical power quality and voltage disturbances that occur in power systems such as voltage sags and interruptions.1Furthermore, the influence of the aforementioned equipment on the power system is analyzed within the context of a distribution network.

Método De Modulação Pwm Para Equilíbrio Das Tensões Dos Capacitores Do Barramento Cc Em Conversores Multiníveis Com Diodos De Grampeamento
Authors: Grigoletto Felipe Bovolini , Pinheiro Humberto
Published: October 2018

Este artigo apresenta uma nova estratégia de modulação para conversores PWM com diodos de grampeamento. Esta estratégia elimina os desequilíbrios de tensão entre os capacitores do barramento CC, que é o principal problema apresentado por esta topologia, bem como as ondulações de baixa frequência que a mesma apresenta operando com altos índices de modulação e baixo fator de potência. Com objetivo de facilitar a extensão dos resultados para um numero qualquer de níveis, a modulação baseada na comparação com portadora foi adotada nesse artigo onde as tensões modulantes são escolhidas de forma a garantir a máxima utilização da tensão do barramento CC na faixa linear de operação do inversor. Para assegurar as adequadas tensões nos capacitores no barramento CC, mesmo na presença de não idealidades no circuito, um método de controle e um controlador são desenvolvidos. Finalmente, o bom desempenho do método de modulação proposto é demonstrado por meio de simulações de um conversor com diodos de grampeamento de quatro níveis.

São apresentados o princípio da compensação série, a estratégia de modulação e uma breve revisão sobre condicionadores de tensão. É selecionada e analisada uma topologia de condicionador de tensão para validar a teoria explanada. Apresenta-se uma técnica de controle linear capaz de prover o condicionamento da tensão de saída frente às perturbações do sistema. Apresentam-se os ensaios de um protótipo de 10 kVA, validando a teoria e comprovando as características da topologia proposta.

Published: October 2018

Neste artigo é discutido o uso da técnica de controle baseado em passividade aplicada a conversores estáticos do tipo abaixador de tensão (buck) e elevadores de tensão (boost) operando como corretores ativos de fator de potência (CFP). É proposta uma modelagem do tipo Euler-Lagrange do conversor e, a partir deste modelo, a definição das técnicas de controle por passividade direta (pela tensão no capacitor) e indireta (pela corrente no indutor) com o reconhecimento da impedância de uma carga resistiva por um método adaptativo. Por se tratar de uma técnica de controle não linear, não é necessário realizar a linearização no ponto de operação mais critico, garantindo o funcionamento do CFP em toda a faixa de operação, atendendo os preceitos da resolução da ANEEL - Agência Nacional de Energia Elétrica.

Authors: Neto T. R. Fernandes , Pontes R. S. T.
Published: October 2018

This work aims at the design of a roped elevator prototype, which uses a linear induction motor (LIM) as a traction machine. It is also concerned with the development of a specific inverter to feed the linear motor that allows several ways to drive the elevator through a suitable choice of the RMS voltage levels, angular phase displacement and electrical frequency of the output voltage. The result tries to establish a new concept for elevators through a new construction technique and assembly of the system with counterweight, which increases the reliability and comfort with cost reduction.
