Vibration analysis of a dual rotor bearing double casing system with pedestal looseness and multi stage turbine blade casing rub
Year: 2020

Pedestal looseness and rotor stator rub are two common faults in rotating machines. To increase the thrust weight ratio and enhance fuel efficiency of aero engines, the structural design of a dual rotor system has to address these two kinds of common faults. The aim of this paper is to gain insight into the vibration behaviours of a dual rotor system with pedestal looseness and rotor stator rub. Firstly, a dual rotor bearing double casing system is modelled. After that, considering the effects of two disc imbalances, and pedestal looseness which exists in high pressure rotor, the rub impact fault between the multi stage turbine blades and the multi layer casings is further introduced to the system. In combination with the distribution of soft and hard coatings, the impact stiffness of the rub impact model is adjusted accordingly. Then an experimental study is performed on a dual rotor test rig for verifying the validity of the theoretical model and revealing the dynamic responses at different rotor speed ratio. Finally, taking the stiffness of loosened pedestals, disc eccentricities, speed ratio, and initial gap as the key parameters, the potential effects of pedestal looseness and rub impact on the dynamic characteristics of the dual rotor system are investigated in detail.
Adoption of Precision Farming Tools: The Case of Italian Farmers
Venue: International journal of environmental research and public health
Year: 2020

The process of adopting innovation, especially with regard to precision farming (PF) is inherently complex and social, and influenced by producers, change agents, social norms and organizational pressure. An empirical analysis was conducted among Italian farmers to measure the drivers and clarify "bottlenecks" in the adoption of agricultural innovation. The purpose of this study was to analyze the socio structural and complexity factors that affect the probability to adopt innovations and the determinants that drive an individual's decisions. Preliminary results found high levels of adoption among younger farmers, those that had a high level of education, those with high intensity of information, with large farm sizes, and high labor intensity. A logit model was used to understand the role played by labor intensity and perceived in the adoption process. In light of the Common Agricultural Policy Reform post 2020, the findings suggest relevant policy implications, such as the need to increase awareness of PF tools and foster dissemination of information aimed at reducing the degree of perceived complexity.
Developing Cultural Competency in Engineering Through Transnational Distance Learning
Year: 2016

While cultural competency is a stated priority for engineering education in the United States, as emphasized by Outcome H in the ABET standards, it is often difficult to engage students in immersive international experiences that develop intercultural awareness. Undergraduate engineering students face packed curricula with little or no room for languages and an often unforgiving structure that puts them a year out of course sequences if they do travel for study abroad. In this case study, the authors examine how online education can be a transformational factor in this challenge. When designed to create interactive, engaging learning across nations, online education can support joint international experiences that develop cultural competency without requiring the time and expenses that are often a barrier for students. This online model could easily be scaled up to offer more students an international collaboration opportunity without institutional reliance on study abroad. This online transnational distance learning approach saves students and universities time and money, while accomplishing the intended professional competencies.
Discourses of Global Citizenship Education: The Influence of the Global Middle Classes
Year: 2020

This chapter examines the intersections between a growing 'global middle class' their emplacement within national education systems and subsequent changes within provision of education due to the emergence of this new prominent social group. We begin with an analysis of the discourses that call forth notions of global citizenship and global citizenship education concepts often associated with both the experiences and needs of the global middle classes. We then examine how the growing presence of global middle class students and their families across educational contexts may be shaping the provision of education and potentially altering its intended purposes in some cases. This argument is illustrated by a discussion focusing on the increasing prominence of International Baccalaureate programs worldwide, the integration of cosmopolitan values in local curricula, and a consideration of how mobilities re shape the imaginaries of future destinations.

Knowledge, Attitude and Practice of Antenatal Care Service among Married Women of Reproductive Age Group in Mizan Health Center, South West Ethiopia
Year: 2015

Back ground Antenatal care is a medical and general care that is provided to pregnant women during pregnancy. In Ethiopia as well as in the world maternal mortality is high. Mostly this occurred due to pregnancy related complication because of lack of ad equate antenatal care service.  To assess the level of knowledge, attitude and practice of mothers towards antenatal care service in Mizan health center.  Institutional based descriptive cross sectional study was conducted among married women of reproductive age group who came to Mizan health center from May to August 2014. A Total of 255 women were selected based on systematic random sampling technique after estimating the number of women who came to Mizan health center and they were interviewed by using interviewer administered questionnaire. The data was entered in to Epidata 3.1 and exported to SPSS version 17 for analysis. Finally descriptive analysis was done and data was presented by using tables.  Majority (88.2% of women know about antenatal care and the rest (11.8% do not know about antenatal care. About 70.6% of the respondents wanted to follow antenatal care and the remaining 29.4% of women do not want to follow antenatal care if they get pregnant due to negative attitude. Less than half (47.9% of women practiced antenatal care follow up during their pregnancy time.  Knowledge and attitude of women towards antenatal care was comparatively in better position. But the practice of women was poor. Further research was recommended to identify factors which are associated with practice.  knowledge, attitude, practice, antenatal care, Mizan
Factors Affecting House Ownership in Nigeria; A Probit and Heteroscedastic Probit Model Approach
Year: 2019

With a rapid rate of urbanization in Nigeria, almost half of the population already lives in cities thereby putting great pressure on the country's urban settlement. Fundamental to this problem is the decision to become a homeowner which is an issue of financial and social decision. Thus, this study investigates the nexus between house ownership and socio economic variables of the household head. The study makes use of nation wide cross sectional data of the 2015/2016 General Household Survey (GHS) conducted by the Nigeria Bureau of Statistics. Results show that the main determinants of house ownership in Nigeria are: Occupation, household size, education level, marital status, income and age of household head. The study, therefore, suggests that policies that are targeted at maintaining moderate or lean household size and promoting non farming occupation along gender oriented development policies should be advocated and promoted by policy makers, since these variables are considered critical to increasing house ownership among households in Nigeria.  25/08/2019

TEI Lex 0: A Target Format for TEI Encoded Dictionaries and Lexical Resources
Year: 2018

Achieving consistent encoding within a given community of practice has been a recurrent issue for the TEI Guidelines. The topic is of particular importance for lexical data if we think of the potential wealth of content we could gain from pooling together the information available in the variety of highly structured, historical and contemporary lexical resources. Still, the encoding possibilities offered by the Dictionaries Chapter in the Guidelines are too numerous and too flexible to guarantee sufficient interoperability and a coherent model for searching, visualising or enriching multiple lexical resources. Following the spirit of TEI Analytics [Zillig, 2009] developed in the context of the MONK project, TEI Lex 0 aims at establishing a target format to facilitate the interoperability of heterogeneously encoded lexical resources. This is important both in the context of building lexical infrastructures as such [Ermolaev and Tasovac, 2012] and in the context of developing generic TEI aware tools such as dictionary viewers and profilers. The format itself should not necessarily be one which is used for editing or managing individual resources, but one to which they can be univocally transformed to be queried, visualised, or mined in a uniform way. We are also aiming to stay as aligned as possible with the TEI subset developed in conjunction with the revision of the ISO LMF (Lexical Markup Framework) standard so that coherent design guidelines can be provided to the community (cf.  providing a strict based encoding of sense related information; deprecating dealing with internal and external references in dictionary entries, providing more advanced encodings of etymology (see submission by Bowers, Herold and Romary) as well as defining technical constraints on the systematic use of @xml:id at different levels of the dictionary microstructure. The activity of the group has already lead to changes in the Guidelines in response to specific GitHub tickets.
Guitar profiling technology in metal music production: public reception, capability, consequences and perspectives
Year: 2018

This empirical study explores the guitar profiling technology and its consequences for metal music production. After briefly introducing this technology, the article investigates its public reception in reviews and online discussion boards to explore the subjective perspectives. A sub sequent acoustic experiment tests the capability of the technology. The findings show that many guitar players and producers have been highly skeptical of digital amplification technology because of tonal shortcomings. However, meanwhile many musicians seem convinced of profil ing technology due to its good sound quality that has been confirmed by the experiment too. Since for most metal music genres the sound quality of the electric guitar is very important, the creative practices and economic conditions of its production may likely be hugely affected by this technology. The article concludes by discussing the consequences of profiling technology regarding issues such as democratisation of production tools, changes in professional services, creative potentials and future applications of the technology that may radically change metal music production.
Potential areas for silvopastoral systems based on the ecological niche of two forage crops and three species of conifers
Year: 2020

Ecological niche modeling is a fundamental tool to know the areas suitable for the establishment of silvopastoral systems, based on the environmental requirements of the species.  To model the ecological niche of the forage species Chloris gayana Kunth and Eragrostis curvula (Schrad. Nees, and the conifers Pinus devoniana Lindley, Pinus lawsonii Roezl ex Gordon and Pinus montezumae Lambert and to identify potential areas for silvopastoral systems.  The ecological niche was modeled based on data from georeferenced collection sites in Mexico and 23 environmental variables. Subsequently, areas were identified and the extent, where forage species converge with conifers in both agricultural and forest areas, was estimated.  Potential areas for silvopastoral systems with the five species were found mainly in the Neovolcanic Axis and the Sierra Madre del Sur, with a greater area suitable for agricultural areas compared to forestry areas. The ecological niche models had high predictive capacity with an area under the curve values greater than 0.93. Altitude and annual temperature range were the most important variables. Pinus devoniana had the largest potential area to be intercropped with C. gayana and E. curvula.  Mexico has the potential to establish silvopastoral systems with the species understudy in the center and south of the country, which could contribute to decreasing soil degradation, provide forage for livestock and maintain tree cover for agricultural and forest areas.
Electric vehicle household charging behaviour in Ireland and aims for a carbon neutral electric fleet by 2020
Year: 2015

This paper uses data collected from electric vehicle (EV) household charge points in Ireland to analyse existing EV charging profiles. The potential impacts of increased numbers of EVs in the population on the Irish electrical grid are assessed if EV penetration levels were to increase to different levels in the population. The 2011 census database was used to examine the key demands of the population in terms of their car based work trips for a number of projected growth scenarios. A large proportion of Irish households were identified as being suitable for the purchase of an EV on this basis. The next step in the research examined the potential impact on the electrical grid of the potential charging demand for the projected scenarios. The projected supply capacity within the Irish electrical grid would appear sufficiently capable to absorb the likely power demand from EVs in both 2016 and 2020 scenarios.
Multi Scale Interactive Network for Salient Object Detection
Venue: 2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)
Year: 2020

Deep learning based salient object detection methods achieve great progress. However, the variable scale and unknown category of salient objects are great challenges all the time. These are closely related to the utilization of multi level and multi scale features. In this paper, we propose the aggregate interaction modules to integrate the features from adjacent levels, in which less noise is introduced because of only using small up /down sampling rates. To obtain more efficient multi scale features from the integrated features, the self interaction modules are embedded in each decoder unit. Besides, the class imbalance issue caused by the scale variation weakens the effect of the binary cross entropy loss and results in the spatial inconsistency of the predictions. Therefore, we exploit the consistency enhanced loss to highlight the fore /back ground difference and preserve the intra class consistency. Experimental results on five benchmark datasets demonstrate that the proposed method without any post processing performs favorably against 23 state of the art approaches.

A dynamically adjustable broadband terahertz absorber based on a vanadium dioxide hybrid metamaterial
Year: 2020

A dynamically adjustable terahertz (THz) broadband absorber based on a vanadium dioxide (VO2) hybrid metamaterial is theoretically designed. During the design, we first consider working frequency, bandwidth, excitation method and fabrication process. And then, a commercialized full wave electromagnetic (EM) calculation software CST microwave 2019 based on finite integration technology is used to simulate and optimize the performance of the device. Due to the device is excited by light, it consists of a top layer of VO2 oblique split ring resonator (OSRR) array, a polyimide (PI) spacer and a bottom metal film. The simulation results show that, when the VO2 changes from insulating state to metal state under light stimulus, the absorption increases from 3% to over 90% Meanwhile, when the VO2 is in metallic phase, the bandwidth of absorption greater than 90% reaches to 1.0 THz and the relative bandwidth is about 83% The potential applications of the device are active EM stealth, THz wave detection and thermal imaging. This work paves a new way for simply constructing a low cost dynamically adjustable THz broadband absorber.
PBL Cultivation Mode of Innovative Thinking Ability Based on the Data of WTMF and TCT
Venue: CIPAE
Year: 2021

In order to analyze the characteristics of innovative thinking ability of Chinese students who learn a foreign language (English, French, Japanese and other minority languages) as a second foreign language and accordingly establish a teaching mode, this paper takes foreign language majors in Nanfang College of Sun Yat sen University as subjects to participate in a WTMF (Williams Innovative Thinking Ability Tendency Measurement Form) and a TCT (Test of Creative Thinking) The result shows that students have higher scores in curiosity, challenge and adventure but lower scores in imagination. On the other hand, they performed better in originality but normal in fluency and flexibility. Moreover, data of different genders, grades and foreign language majors shows consistency in fluency, flexibility, originality and creativity. Based on the above investigation and the important role PBL (Project based Learning) has played in improving the cognitive ability which composes of thinking ability, the author designs a PBL cultivation mode by putting forward the thinking training methods into the process of PBL in order to make joint efforts to cultivate college students' innovative thinking ability.
