Design of an automated vibration monitoring system for condition based maintenance of a lathe machine (Case study)
Venue: 2016 International Conference on System Reliability and Science (ICSRS)
Year: 2016

This article presents an automated vibration monitoring system for a lathe machine. This study was motivated by the fact that machine production time was wasted during planned maintenance when, most times, the machines did not require any maintenance at all. Also, the periodic intervals used did not depict the correct ageing of the machine components which resulted in unexpected failure of the machine. Planned maintenance schedules are done with the assumption that the machine is going to breakdown after a certain period of time. The aim of this research was to come up with a vibration monitoring system for a lathe machine, which included incorporating an electronic circuit in the system, use of liquid crystal display for improved user interface and use of vibration sensors to determine the vibration level of the machine. Experimental research design was used to determine the acceptable ranges of vibration amplitudes in order to classify the amplitude into 4 groups namely: extremely rough, rough, acceptable and smooth. The designed system produced consistent vibration amplitudes for both machining and nonmachining operation. The system used different indicators linked to the main processor of the circuit which monitors the machine real time performance. It was capable of alerting the user when the vibration amplitude was out of range and also to switch off the machine when the vibration threshold was exceeded. The vibration monitoring system helps in damage control and enables preventive measures to be taken before damage occurs.
Il principe, il filosofo, il guerriero
Year: 2019

Al tramonto dell'impero in Occidente, un'Italia ancora aggrappata al mito di Roma, nostalgica dei fasti e degli antichi esempi, accoglie i nuovi dominatori germanici. In un impasto di culture, nell'incontro scontro di distinti valori, due popoli, i Romani e i Goti, sembrano avere raggiunto la capacita di convivere attraverso l'esercizio di funzioni complementari: i primi si giovano della tranquilla ciuilitas, la guerra spetta ai secondi. E allora che la cerchia anicia di Simmaco, di Boezio, di Cassiodoro, assurge a paladina dell'ideologia senatoria, in un estremo tentativo di difesa dell'ormai millenaria cultura classica, sola garanzia di salvezza per la romanitas. La monarchia gotica assume, dunque, una patina di 'romanita' dalla quale i sovrani traggono profitto per distinguersi dagli altri reges gentium e per accreditarsi quali degni eredi dei Cesari. Tale 'rinascita' che coinvolge presto la corte di Ravenna, vede il sua climax nella figura del principe filosofo. Essa e destinata tuttavia a una breve durata. Infatti, di fronte alla incombente minaccia della 'riconquista' bizantina, il mondo gotico non esitera a rivelare il suo vero volto.
The impact of product variety on customers' default acceptance and company perception. Experimental studies for the insurance industry
Year: 2020

Many insurance companies offer a huge variety of products within one insurance category. In particular, there are rarely limits to available insurance products in the online world. Insurance companies can simply combine various insurance sums and service components to meet the needs of different customers. Using experimental studies, the paper analyzes the effect of defaults on customer choices and customers' perceptions of the company when insurance companies offer more or less variety. The results show that defaults have an influence when a smaller, rather than a larger, number of insurance options is available. The premium image of an insurance company can only be influenced by defaults when customers know about the different default settings. Viele Versicherungsunternehmen bieten ihren Kunden eine grosse Produktvielfalt an. Vor allem online sind hier kaum Grenzen gesetzt: Durch die Kombination verschiedener Versicherungssummen und Leistungskomponenten konnen unterschiedliche Kundenbedurfnisse leicht erfullt werden. In diesem Beitrag wird mittels zweier experimenteller Studien die Wirkung von Voreinstellungen, sog. Defaults, auf das Kaufverhalten von Kunden und deren Wahrnehmung des Versicherungsunternehmens untersucht, wenn Versicherungsunternehmen eine kleinere oder grossere Produktauswahl anbieten. Es wird gezeigt, dass Defaults das Kaufverhalten nur dann beeinflussen, wenn eine kleinere Anzahl an Versicherungsprodukten angeboten wird. Die kundenseitige Wahrnehmung des Versicherungsunternehmens als Premium Anbieter kann nur dann durch Defaults beeinflusst werden, wenn Kunden die verschiedenen Default Einsatzmoglichkeiten kennen.
Assessing genomic diversity and signatures of selection in Jiaxian Red cattle using whole genome sequencing data
Venue: BMC genomics
Year: 2021

Native cattle breeds are an important source of genetic variation because they might carry alleles that enable them to adapt to local environment and tough feeding conditions. Jiaxian Red, a Chinese native cattle breed, is reported to have originated from crossbreeding between taurine and indicine cattle; their history as a draft and meat animal dates back at least 30 years. Using whole genome sequencing (WGS) data of 30 animals from the core breeding farm, we investigated the genetic diversity, population structure and genomic regions under selection of Jiaxian Red cattle. Furthermore, we used 131 published genomes of world wide cattle to characterize the genomic variation of Jiaxian Red cattle.  The population structure analysis revealed that Jiaxian Red cattle harboured the ancestry with East Asian taurine (0.493) Chinese indicine (0.379) European taurine (0.095) and Indian indicine (0.033) Three methods (nucleotide diversity, linkage disequilibrium decay and runs of homozygosity) implied the relatively high genomic diversity in Jiaxian Red cattle. We used thp, CLR, F ST and XP EHH methods to look for the candidate signatures of positive selection in Jiaxian Red cattle. A total number of 171 (thp and CLR) and 17 F ST and XP EHH) shared genes were identified using different detection strategies. Functional annotation analysis revealed that these genes are potentially responsible for growth and feed efficiency CCSER1 meat quality traits ROCK2 PPP1R12A, CYB5R4 EYA3 PHACTR1 fertility RFX4 SRD5A2 and immune system response SLAMF1 CD84 and SLAMF6  We provide a comprehensive overview of sequence variations in Jiaxian Red cattle genomes. Selection signatures were detected in genomic regions that are possibly related to economically important traits in Jiaxian Red cattle. We observed a high level of genomic diversity and low inbreeding in Jiaxian Red cattle. These results provide a basis for further resource protection and breeding improvement of this breed.
Minimally invasive endodontics and permanent restorations of endodontically treated teeth: literature review
Year: 2020

The primary goal of endodontic therapy is the long term survival of a functional tooth through the prevention and/or treatment of apical periodontitis. However, successful endodontic outcomes depend on many factors, such as the structural integrity of the tooth after root canal preparation and the quality of the final restoration. The field of endodontics is continuously changing due to the introduction of new techniques and technological advances. Currently, minimally invasive endodontics is considered as the recommended approach during root canal therapy, with permanent restorative decisions saved for the postoperative period. Various materials and techniques have been developed and/or proposed to increase the life span of endodontically treated teeth while maintaining adequate root strength and maintaining the balance between biological, mechanical, adhesive, functional, and esthetic parameters. This critical review aims to assess the literature on recent trends in conservative endodontic treatment and adhesive dentistry for the restoration of endodontically treated teeth.
Fast and accurate computation of surface normals from range images
Venue: 2011 IEEE International Conference on Robotics and Automation
Year: 2011

The fast and accurate computation of surface normals from a point cloud is a critical step for many 3D robotics and automotive problems, including terrain estimation, mapping, navigation, object segmentation, and object recognition. To obtain the tangent plane to the surface at a point, the traditional approach applies total least squares to its small neighborhood. However, least squares becomes computationally very expensive when applied to the millions of measurements per second that current range sensors can generate. We reformulate the traditional least squares solution to allow the fast computation of surface normals, and propose a new approach that obtains the normals by calculating the derivatives of the surface from a spherical range image. Furthermore, we show that the traditional least squares problem is very sensitive to range noise and must be normalized to obtain accurate results. Experimental results with synthetic and real data demonstrate that our proposed method is not only more efficient by up to two orders of magnitude, but provides better accuracy than the traditional least squares for practical neighborhood sizes.
Australia's shifting global engagement: the stuttering rise of financial services and city based competitiveness
Year: 2018

A key theme of Global Restructuring (R. H. Fagan and M. Webber. 1994.  The Australian Experience. Melbourne: Oxford University Press) is the dramatic rise of financial capital flows into and out of Australia commencing with the financial deregulation measures of the early 1980s. The book's concern is with the impacts of this deregulation on the materials sectors of the Australian economy, chiefly on the food, manufacturing and minerals sectors. In the book's back story, the Australian banks emerge as institutions able to appropriate value from the overall package of changes. This paper looks at aspects of the Australian financial sector 20 years on from the Fagan and Webber analysis. Reflecting on data collected after 1994 the paper outlines key changes in the industry mix within the Australian economy and, in particular, the rise of financial and business services. In so doing it assesses the shifts in the financial and business services sector that have occurred since the time of Global Restructuring and presents an analysis of these shifts in the context of the rise of international financial services centres, especially in the Asian region. Based on these findings and assessments, the paper proposes a research agenda for scholars interested in the competitiveness of Australian firms, especially in the context of opportunities for financial services growth within the wider region.
Blue, green and grey water embodied in food supply chain in China
Year: 2018

Food trade is transferring the water embodied in food production, which plays important role in balancing water resources between dry and wet regions. To identify the impact of food trade on reallocating water and pathways to mitigate the trade offs between food security and water resource conservation, we built food based virtual blue, green and grey water network. The gravity model and linear programming optimization were used to model interprovincial food trade of China in 2015, and the regional blue, green and grey water footprint of food crops were inventoried. Combing the food trade network and water footprint, the food based virtual blue, green and grey water network was built and used to quantify the water relationship along with national food supply chain. Our results showed that the proportion of green and grey water for the total water consumption were huge, while whose impacts were traditionally neglected. Especially, the food trade is playing important role in transferring the water used for assimilating the pollution. By identifying the critical food trade pathways, we aim to provide insights for reducing the structural tensions between spatial water reallocation and national food security.
CRYPTOCURRENCY AND BLOCKCHAIN BASED DATABASE TO GUARD DATA INTEGRITY IN CLOUD COMPUTING ENVIRONMENT
Year: 2018

Blockchain is a user friendly hybrid wallet. It stores an encrypted version of your wallet online but decryption happens in your browser. For security reasons, you should always use the browser extension and email backups .It helps to share the digital ledger in both public and private sectors. It also reduces the risk of fraud transaction. This technology will increase the trust and integrity in the flow of transaction. It is a distributed peer to peer network where nontrusting members can interact with each other without a trusted intermediary. Here we discuss how this mechanism works and also look into smart contracts scripts that reside on the blockchain which allow to automate this multi processes concept.
Validation of the Pornography Consumption Inventory in a Sample of Male Brazilian University Students
Venue: Journal of sex marital therapy
Year: 2015

Few measures are available to examine pornography use constructs, and this can compromise the reliability of statements regarding harmful use of pornography. This study aimed to confirm the factorial validity and internal consistency of the Pornography Consumption Inventory in a sample of male Brazilian university students. The inventory consists of a 4 factor, 15 item, 5 point Likert type scale. After translation and back translation of the inventory, it was administered to 100 male medical students. An initial model that included all 15 items of the inventory showed some substandard fit indices. Therefore, another model was tested, excluding an item that had loaded onto two different factors. Goodness of fit indices were better for the new model. Overall, findings from this study support using the inventory on Portuguese speaking individuals. With additional replication across populations, other settings, and treatment seeking patients, the Pornography Consumption Inventory could also potentially be shortened to 14 items.
Distilling the Knowledge From Handcrafted Features for Human Activity Recognition
Venue: IEEE Transactions on Industrial Informatics
Year: 2018

Human activity recognition is a core problem in intelligent automation systems due to its far reaching applications including ubiquitous computing, health care services, and smart living. Due to the nonintrusive property of smartphones, smartphone sensors are widely used for the identification of human activities. However, unlike applications in vision or data mining domain, feature embedding from deep neural networks performs much worse in terms of recognition accuracy than properly designed handcrafted features. In this paper, we posit that feature embedding from deep neural networks may convey complementary information and propose a novel knowledge distilling strategy to improve its performance. More specifically, an efficient shallow network, i.e. single layer feedforward neural network (SLFN) with handcrafted features is utilized to assist a deep long short term memory (LSTM) network. On the one hand, the deep LSTM network is able to learn features from raw sensory data to encode temporal dependencies. On the other hand, the deep LSTM network can also learn from SLFN to mimic how it generalizes. Experimental results demonstrate the superiority of the proposed method in terms of recognition accuracy against several state of the art methods in the literature.
Infodemic and the spread of fake news in the COVID 19 era
Venue: European journal of emergency medicine official journal of the European Society for Emergency Medicine
Year: 2020

March, while the pandemic due to SARSCoV 2 spread widely in Europe, the French Minister of Health, Oliver Veran tweeted: 'The intake of anti inflammatory drugs (ibuprofen, cortisone, could be a factor in worsening the infection. If you have a fever, take acetaminophen. If you are already taking anti inflammatory drugs or in doubt, ask your doctor for advice'  As the hours go by, the tweet garnered the consent of more and more 'followers' and, 3 days later, the 're tweets' were over 40 000. The University Hospital of Vaud in Lausanne among others considered the news as authentic and correct, so claims: 'For the current state of knowledge, the use of anti inflammatory drugs (ibuprofen, ketoprofen, naproxen, diclofenac, etc. is not recommended in case of influenza like illness possibly caused by COVID 19. Paracetamol is recommended in the event of fever requiring treatment' In the transmission of the news, one of the 'accused' classes of drugs was exonerated (e.g. any reference to cortisone disappeared) At the same time, the preference given to paracetamol became quite a strong recommendation  The British Medical Journal also felt compelled to relaunch the news, reporting some expert opinions on this matter
A party system in flux: the Swedish parliamentary election of September 2018
Venue: West European Politics
Year: 2019

In the Swedish parliamentary election of 7 September 2018, the biggest parties, the Social Democrats and the Moderates, both lost votes compared to their scores in the previous election, but not as many as they had feared. Commensurately, the radical right challenger party, the Sweden Democrats (SD) which had seemed certain to profit from Sweden's dramatic experience of the European migration crisis, did well, but not as well as it had hoped. The result left the array of parliamentary forces fragmented and finely balanced. Only after months of negotiations could a government be formed. Eventually, the incumbent coalition received a renewed parliamentary mandate. At the same time, the party system was transformed.
Decisive Influence of the Metal in Multifunctional Gold, Silver, and Copper Metallacycles: High Quantum Yield Phosphorescence, Color Switching, and Liquid Crystalline Behavior.
Venue: Inorganic chemistry
Year: 2018

Three cyclic trinuclear pyrazolate complexes with Au(I) Ag(I) or Cu(I) have been studied. These complexes have interesting and distinct optical and thermal properties depending on the metal, namely, liquid crystalline behavior, red or deep red phosphorescence at room temperature, thermoluminochromism, and response to silver ions. The selected ligand, 4 hexyl 3,5 dimethylpyrazolate, maximizes the effect that the nature of the metals has on the properties of the complexes, thus allowing the intermolecular metallophilic interactions to be responsible for the optical properties. Moreover, the gold and silver complexes show columnar liquid crystal phases at high temperature. All of the complexes have good solubility properties for processing as poly(methyl methacrylate) (PMMA) doped films. Films of the gold, silver, and copper complexes show interesting optical behavior such as wide range color switching or phosphorescence turn on upon cooling. In addition, films of the gold complex show a bright color switching (red to blue) in the presence of silver ions. The gold and copper complexes are bright phosphors with phosphorescent quantum yields of 90% in PMMA films, the highest values reported for this class of compounds at room temperature.
Neighborhood Change and Crime in the Modern Metropolis
Venue: Crime and Justice
Year: 2010

Few empirical studies of crime have treated neighborhoods as dynamic entities, by examining how processes of growth, change, and decline affect neighborhood rates of crime. From a small yet burgeoning collection of dynamic research related to population migration including population loss, gentrification, development and demolition of public housing, home ownership and home foreclosure, and immigration we know that neighborhood change, even when it leads to socioeconomic improvements, tends to have a destabilizing influence that results in increases in crime in the short term. This occurs, in part, because residential turnover undermines informal social control. There is evidence across a variety of neighborhood changes, including population loss from central cities and gentrification, that population migration is a cause and consequence of crime. However, too few studies pay adequate attention to how methodological choices affect inferences about the effects of neighborhoods on crime, and not much is known about the relationship between neighborhood change and crime, especially regarding causal mechanisms. Longitudinal data on neighborhood social and cultural processes and population migration are needed to advance our understanding of neighborhood change and crime.
Specializing Word Vectors by Spectral Decomposition on Heterogeneously Twisted Graphs
Venue: COLING
Year: 2020

Traditional word vectors, such as word2vec and glove, have a well known inclination to conflate the semantic similarity with other semantic relations. A retrofitting procedure may be needed to solve this issue. In this work, we propose a new retrofitting method called Heterogeneously Retrofitted Spectral Word Embedding. It heterogeneously twists the similarity matrix of word pairs with lexical constraints. A new set of word vectors is generated by a spectral decomposition of the similarity matrix, which has a linear algebraic analytic form. Our method has a competitive performance compared with the state of the art retrofitting method such as AR (CITATION) In addition, since our embedding has a clear linear algebraic relationship with the similarity matrix, we carefully study the contribution of each component in our model. Last but not least, our method is very efficient to execute.
Moral Dilemmas in Chinese Philosophy: A Case Study of the Lienu Zhuan
Year: 2016

From classical antiquity to contemporary times, challenging situations of dilemmatic or paradoxical nature continue to fascinate both scholars and the casual reader. Although Western literature provides a fruitful source of philosophical discussion on the circumstances under which a morally competent agent faces incompatible moral requirements, Sinology has rarely accepted the idea of moral dilemmas in Chinese philosophy in general and Confucianism in particular. The present paper explores moral and morally motivated dilemmas in Liu Xiang's Liu Xiang Lienu Zhuan Lie Nu Chuan and the philosophical strategies employed for their resolution within the framework of the Confucian tradition, emphasizing similarities with Western traditions such as Greek tragedy or Thomistic philosophy.
