    2017-07-01

    Full Text Available Contour Crafting is a novel technology in construction industry based on 3D printing that uses robotics to construct free form building structures by repeatedly laying down layers of material such as concrete. It is actually an approach to scale up automatic fabrication from building small industrial parts to constructing buildings. However, there are little information about contour crafting (CC in current use; present paper aims to describe the operational steps of creating a whole building by the machine reviewing relevant literature. Furthermore, it will represent the advantages of CC usage compared to traditional construction methods, as well as its applicability in construction industry.

  2. Constructing knowledge through perceptual processes in making craft-art

    Full Text Available The focus of the study is on the knowledge that is constructed through perceptual processes during craft making in the context of the Finnish Basic Education in the Arts (BEA system. Craft studies in the BEA are defined as craft-art. The research method used is the grounded theory. The data consists of seven interviews and participant observations. Participants in the study are adolescents who study craft-art in the BEA system in Visual Art School, Aimo in Hämeenlinna. The aim of the article is to present, define and reflect on the concepts, properties and dimensions concerning perceptual processes that are discovered in this stage of the study following grounded theory procedures. The perceptual processes are an essential means of constructing knowledge in craft-art. Consequently, one aim of the study is to discuss how these processes are connected to various types of knowledge. The perceptual processes are described by seven concepts: imitative, anticipative, evaluative, experimental, emotional, temporal and bodily perceptions. They indicate on a conceptual level the characteristic of knowledge constructed through perceptual processes in craft-art. Further, theconcepts have several properties that can vary dimensionally between two qualities. The properties are activity, function and position. The dimensions of the properties vary from active to passive, formal to informal and internal to external. In conclusion, the concepts can describe a large range of incidents in different situations. They also seem to describe well the practice of  craft-art and there are several connections with pre-existing concepts of knowledge.Keywords: Craft, Knowledge, Perceptual process, Basic Education in the Arts, Grounded Theory

    1980-01-01

    This paper reports on a research study whose objective was to determine the most influential factors adversely affecting craft productivity in nuclear power plant construction from the perspective of the tradesmen employed at the sites. Data were collected through the use of a questionnaire survey and group interview sessions, predominantly with workmen, at six nuclear power plant construction projects. Craftsmen were chosen as the major data base because of their awareness of how their time would actually be spent on the project. Topics considered include the factors influencing craft productivity, material availability, redoing work, crew interfacing, overcrowded work areas, instruction time, inspection delays, craft turnover, craft absenteeism, foreman changes, foreman incompetence, engineering design lead time, comprehensive scheduling of the design function, the responsibility of the utility, value engineering, plant standardization, the effective utilization of the planning and scheduling system, and the labor-management committee

    2017-01-01

    We developed and validated a scale to measure employees' perceived opportunity to craft (POC) in two separate studies conducted in the Netherlands (total N = 2329). POC is defined as employees' perception of their opportunity to craft their job. In Study 1, the perceived opportunity to craft scale (POCS) was developed and tested for its factor structure and reliability in an explorative way. Study 2 consisted of confirmatory analyses of the factor structure and reliability of the scale as well as examination of the discriminant and criterion-related validity of the POCS. The results indicated that the scale consists of one dimension and could be reliably measured with five items. Evidence was found for the discriminant validity of the POCS. The scale also showed criterion-related validity when correlated with job crafting (+), job resources (autonomy +; opportunities for professional development +), work engagement (+), and the inactive construct cynicism (-). We discuss the implications of these findings for theory and practice.

    2017-12-01

    The data presented in this article is an original data on "Investigating the role of onsite learning in the optimisation of craft gang's productivity in the construction industry". This article describes the constraints influencing craft gang's productivity and the influence of onsite learning on the blockwork craft gang's productivity. It also presented the method of data collection, using a semi-structured interview and an observation method to collect data from construction organisations. We provided statistics on the top most important constraints affecting the craft gang's productivity using 3-D Bar charts. In addition, we computed the correlation coefficients and the regression model on the influence of onsite learning on craft gang's productivity using the man-hour as the dependent variable. The relationship between blockwork inputs and cycle numbers was determined at 5% significance level. Finally, we presented data information on the application of the learning curve theory using the unit straight-line model equations and computed the learning rate of the observed craft gang's blockwork repetitive work.

  6. CRAFTING THE MICROWORLD: HOW ROBERT HOOKE CONSTRUCTED KNOWLEDGE ABOUT SMALL THINGS.

    Science.gov (United States)

    Lawson, Ian

    2016-03-20

    This paper investigates the way in which Robert Hooke constructed his microscopical observations. His Micrographia is justifiably famous for its detailed engravings, which communicated Hooke's observations of tiny nature to his readers, but less attention has been paid to how he went about making the observations themselves. In this paper I explore the relationship between the materiality of his instrument and the epistemic images he produced. Behind the pictures lies an array of hidden materials, and the craft knowledge it took to manipulate them. By investigating the often counter-theoretical and conflicting practices of his ingenious microscope use, I demonstrate the way in which Hooke crafted the microworld for his readers, giving insight into how early modern microscopy was understood by its practitioners and audience.

    Full Text Available The research task was to describe and construct theoretical background for Craft Sense in early education. Craft Sense represents a learner’s skill for obtaining Sloyd (Craft, Design & Technology related knowledge, skills and understanding. The development of Craft Sense is based on producing artefacts and evaluating the production process. In this research, the concept of Craft Sense is based on the integration of Sloyd and meta-cognitive regulation of learning activities. Based on theoretical information, an empirical research question was formulated: “What kind of Craft Sense do children have in early education Sloyd?” The method of study was assessing picture supported learning on a Sloyd course for young children. The data was analyzed by qualitative content analysis and Child Behaviour Rating Scale (CBRS. Findings indicate that the development of children’s Craft Sense can be supported with pictures. Furthermore, the CBRS can be used to evaluate and understand children’s Craft Sense. Keywords: Craft Sense, Sloyd, Sloyd Education, Meta-cognition

  9. The meaning of craft: craft makers' descriptions of craft as an occupation.

    Pöllänen, Sinikka

    2013-05-01

    The aim of this study is to examine how craft makers describe the meaning of craft as an activity in relation to their well-being. The study is based on an analysis of the written narratives of 92 textile craft makers aged 16 to 84. Based on the results, the well-being enhancing nature of craft as a meaningful occupation for those interested in crafting is evident. The significance of craft making as an occupation is described by the following three themes: (a) "the meaning and value of crafts", (b) "the feelings experienced during craft activity", and (c) "the holisticity and intentionality of craft-making". As an activity and a metaphor, craft making helped the participants to adjust to life situations. Elements of craft that enhance well-being can be traced to both the artefacts and the sense of achievement gained in producing them. The effects of craft include personal growth, development of physical and cognitive skills, control of one's body, thoughts, and feelings, as well as cultural and social awareness. The results indicate that the participants noticed the significance of craft as an agony- and stress-reducing and mind-calming activity. Holistic craft and ordinary craft played different roles in maintaining well-being.

    Zhadanovsky, Boris; Sinenko, Sergey

    2018-03-01

    Economic indicators of construction work, particularly in high-rise construction, are directly related to the choice of optimal number of machines. The shortage of machinery makes it impossible to complete the construction & installation work on scheduled time. Rates of performance of construction & installation works and labor productivity during high-rise construction largely depend on the degree of provision of construction project with machines (level of work mechanization). During calculation of the need for machines in construction projects, it is necessary to ensure that work is completed on scheduled time, increased level of complex mechanization, increased productivity and reduction of manual work, and improved usage and maintenance of machine fleet. The selection of machines and determination of their numbers should be carried out by using formulas presented in this work.

    Full Text Available This paper describes the views of student teachers of craft about the future of craft as a school subject. The study was conducted at the University of Turku, Department of Teacher Education, in Rauma in 2014. The literature review revealed that the subject of craft in Finnish basic education is understood as a dialog between the maker and the materials. However, teaching and learning craft in schools and in teacher education has a strong gender-based tradition. The aim of this study is to investigate student teachers’ understanding of craft as a school subject in the future and their solutions to teaching craft in basic education. The data were collected from essays (N = 20 written by student teachers of craft. The essays were analyzed qualitatively using content analysis. The results showed that the student teachers of craft viewed holistic craft, reflective action readiness, entrepreneurial behaviour, multiple skills, the use of versatile materials, and craft as sources of pleasure and the main solutions for the future of craft as a subject.

  19. DEVELOPMENT OF INTERACTIVE MULTIMEDIA COURSEWARE (E-CRAFT FOR CRAFT EDUCATION

    Directory of Open Access Journals (Sweden)

    Salyani OSMAN,

    2012-08-01

    Full Text Available The way of teaching and learning traditional crafts have always used traditional apprenticeship learning methods where the expert facilitates transfer of practice skill sets to novices. As a craft has been taught in conventional approach, the students and experts have been facing several problems especially when expert needs to teach a group of students. An appropriate mapping of craft education and Information and Communication Technologies using Multimedia technology for instance, has the potential in transforming traditional craft learning into more flexible environment. This paper reports on a research project on development of an interactive multimedia courseware package for teaching and learning traditional craft called e-CRAFT. The e-CRAFT is specially designed for songket weaving course taught to certificate and diploma students from Fakulti Seni Kraf Tenunan in their first year study at Institut Kraf Negara, Malaysia (National Craft Institute. The courseware was developed in a web-based environment and overall development process was based on the Dick and Carey's process model and conceptual Instructional Design framework. It is made up of eight learning modules: Introduction, Materials & Tools, Knowing Motifs, Learn How to Weave, Quizzes & Test, Online Discussion, Glossary and Help module. In order to test whether the courseware is suitable in terms of usability, pilot testing was done to a sample of 10 students. The results from pilot test received positive feedback which signifies the courseware is considered acceptable for effectiveness study and help for further improve of the e-CRAFT courseware.

    Constructive machine learning enables the automated generation of novel chemical structures without the need for explicit molecular design rules. This study presents the experimental application of such a generative model to design membranolytic anticancer peptides (ACPs) de novo. A recurrent neural network with long short-term memory cells was trained on alpha-helical cationic amphipathic peptide sequences and then fine-tuned with 26 known ACPs. This optimized model was used to generate unique and novel amino acid sequences. Twelve of the peptides were synthesized and tested for their activity on MCF7 human breast adenocarcinoma cells and selectivity against human erythrocytes. Ten of these peptides were active against cancer cells. Six of the active peptides killed MCF7 cancer cells without affecting human erythrocytes with at least threefold selectivity. These results advocate constructive machine learning for the automated design of peptides with desired biological activities. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  1. Crafting in context: Exploring when job crafting is dysfunctional for performance effectiveness.

    Science.gov (United States)

    Dierdorff, Erich C; Jensen, Jaclyn M

    2018-05-01

    Job crafting theory purports that the consequences of revising one's work role can be simultaneously beneficial and detrimental. Previous research, however, has almost exclusively emphasized the beneficial outcomes of job crafting. In the current study, we proposed dysfunctional consequences of crafting for performance-related outcomes in the form of a U-shaped relationship between job crafting and performance effectiveness (managerial ratings of job proficiency and peer ratings of citizenship behavior). We further predicted that elements of the task context (autonomy and ambiguity) and the social context (interdependence and social support) moderate these curvilinear relationships. Consistent with previous research, job crafting displayed positive and linear effects on work-related attitudes (job satisfaction and affective commitment). Consistent with our predictions, moderate levels of crafting were associated with dysfunctional performance-related outcomes and features of work context either exacerbated or dissipated these dysfunctional consequences of job crafting for individuals.

    2013-07-01

    Caisson is one of the important representations of the Minnan (southern Fujian) temple architecture craft techniques and decorative aesthetics. The special component design and group building method present the architectural thinking and personal characteristics of great carpenters of Minnan temple architecture. In late Qing Dynasty, the appearance and style of caissons of famous temples in Taiwan apparently presented the building techniques of the great carpenters. However, as the years went by, the caisson design and craft techniques were not fully inherited, which has been a great loss of cultural assets. Accordingly, with the caisson of Fulong temple, a work by the well-known great carpenter in Tainan as an example, this study obtained the thinking principles of the original design and the design method at initial period of construction through interview records and the step of redrawing the "Tng-Ko" (traditional design, stakeout and construction tool). We obtained the 3D point cloud model of the caisson of Fulong temple using 3D laser scanning technology, and established the 3D digital model of each component of the caisson. Based on the caisson component procedure obtained from interview records, this study conducted the digital simulation of the caisson component to completely recode and present the caisson design, construction and completion procedure. This model of preserving the craft techniques for Minnan temple caisson by using digital technology makes specific contribution to the heritage of the craft techniques while providing an important reference for the digital preservation of human cultural assets.

    2016-06-01

    Full Text Available The aim of this study was to explore a preschooler craft-making process in which 18 preschool novices cut pieces for fabric bags and designed and printed patterns to decorate the bags. Through the task, children were familiarised with a small-scale holistic craft process. The intention was to determine how preschoolers perceived, verbalised and interpreted the craft-making process and how children used bodily expressions when explaining a learned craft skill. The present study relies on the videographic method: two preschool groups’ stamp printing activities were recorded, and each child was interviewed individually. Children’s embodied expressions were particularly in focus in video analysis. The results reveal that all the children were able to sufficiently explain the making phase, however, some children compensated for missing words using bodily and facial expressions and gestures when talking about making. The results showed that children worked logically, and the skill learning phases of perceiving, making, and interpretation were revealed from their learning.

  15. Machine Learning for Slow but Steady Interplanetary Construction

    Science.gov (United States)

    2017-01-01

    For prolonged manned missions to destinations such as the moon and Mars, there is a need for significant infrastructure construction ahead of time, such as habitats and landing pads. Unfortunately we have little experience in remote construction and using conventional methods is likely to be expensive, cumbersome and unreliable. Fortunately these challenges may be overcome by taking advantage of the long lead time for such missions and using teams of small and slow construction robots. We propose using teams of simple autonomous robots for this purpose that would perform continuous construction over a period of many years or even decades. While individual robot reliability will be low over such long time frames, system reliability will be maintained by using machine learning over simulations to achieve coordination and reconfigurations in the event of lost robots.

    The present study was designed to gain knowledge of the relationship between employees’ perceived opportunities to craft, their actual job crafting behavior and, in line with JD-R theory, subsequently their work engagement and performance. Although scholars have suggested that employees’ perceived opportunities to craft their job may predict their actual job crafting behavior, which may have consequences for their well-being and performance, no study has examined the relationships between these variables. We collected data among a heterogeneous group of Dutch employees (N = 2090). Participants of the study reported their perceived opportunities to craft, job crafting behavior, work engagement and performance. Results indicated that individuals who experience a high level of opportunities to craft reported higher levels of job crafting behavior. In turn, perceived opportunities to craft and job crafting behavior related to higher levels of work engagement and subsequently performance. We discuss the implications of these findings for theory and practice. PMID:29118729

  4. USAGE OF CONSTRUCTION-ORIENTED SOFTWARE SCAD FOR ANALYSIS OF WORK OF MACHINE-BUILDING STRUCTURES

    Directory of Open Access Journals (Sweden)

    D. О. Bannikov

    2018-02-01

    Full Text Available Purpose. In the case of analysis of work of the machine-building structures, the direct usage of construction-oriented software developments is impossible, since ideology and methodology for solving various tasks in construction and machine-building are different. Therefore, in the conducting of practical calculations, there is a need for a certain adjustment of the approaches put in the program complexes and their adaptation to the engineering industry. The presentation of the author's experience of the construction-oriented software SCAD usage for Windows for analyzing the work of various machine-building structures, their components and assemblies is the immediate purpose of the publication. Methodology. During a long period of time the author was engaged in analyzing the work of building, mainly thin-walled, steel structures using the Finite Element Method based on the SCAD for Windows software package. At the same time, a considerable number of machine-building structures were considered, including railroad rolling stock units. Most of these tasks grew into a scientific and research problem that needed to be thoroughly researched and analyzed before giving design recommendations. Findings. The publication presents more than a dozen different tasks, typical for the machine-building industry, which the author had to deal with. Static and quasi-static problems, the problem of motion in time, the contact problem, the problem of the cracks deve-lopment, the physical and geometric non-linearity are among them. Accordingly, for each of these problems the main challenges, features and practical techniques developed during the work are presented, as well as the constructed finite element models are presented as an illustration. Originality. The experience of construction-oriented software product usage on the basis of the Finite Element Method for analyzing of the work of machine-building structures is generalized. A number of practical methods and

    Colonoscopy is a standard method for screening polyps by highly trained physicians. Miss-detected polyps in colonoscopy are potential risk factor for colorectal cancer. In this study, we investigate an automatic polyp classification framework. We aim to compare two different approaches named hand-craft feature method and convolutional neural network (CNN) based deep learning method. Combined shape and color features are used for hand craft feature extraction and support vector machine (SVM) method is adopted for classification. For CNN approach, three convolution and pooling based deep learning framework is used for classification purpose. The proposed framework is evaluated using three public polyp databases. From the experimental results, we have shown that the CNN based deep learning framework shows better classification performance than the hand-craft feature based methods. It achieves over 90% of classification accuracy, sensitivity, specificity and precision.

    Full Text Available Abstract Drilling machine is used for boring holes in various materials and used in woodworking metalworking construction and do-it-yourself projects. When the machine operate for a long time the temperature increases and so we need to control the temperature of the machine and some lubrication system need to apply to reduce the temperature. Due to the improvement of technology the system can be controlled with wireless network. This control system use Window Communication Foundation WCF which is the latest service oriented technology to control all drilling machines in industries simultaneously. All drilling machines are start working when they received command from server. After the machine is running for a long time the temperature is gradually increased. This system used LM35 temperature sensor to measure the temperature. When the temperature is over the safely level that is programmed in host server the controller at the server will command to control the speed of motor and applying some lubrication system at the tip and edges of drill. The command from the server is received by the client and sends to PIC. In this control system PIC microcontroller is used as an interface between the client computer and the machine. The speed of motor is controlled with PWM and water pump system is used for lubrication. This control system is designed and simulated with 12V DC motor LM35 sensor LCD displayand relay which is to open the water container to spray water between drill and work piece. The host server choosing to control the drilling machine that are overheat by selecting the clients IP address that is connected with that machine.

  3. Historical and Epistemological Reflections on the Culture of Machines around the Renaissance: How Science and Technique Work?

    Directory of Open Access Journals (Sweden)

    Raffaele Pisano

    2014-10-01

    Full Text Available This paper is divided into two parts, this being the first one. The second is entitled ‘Historical and Epistemological Reflections on the Culture of Machines around Renaissance: Machines, Machineries and Perpetual Motion’ and will be published in Acta Baltica Historiae et Philosophiae Scientiarum in 2015. Based on our recent studies, we provide here a historical and epistemological feature on the role played by machines and machineries. Ours is an epistemological thesis based on a series of historical examples to show that the relations between theoretical science and the construction of machines cannot be taken for granted, a priori. Our analysis is mainly based on the culture of machines around 15th and 17th centuries, namely the epoch of Late Renaissance and Early Modern Age. For this is the period of scientific revolution and this age offers abundant interesting material for researches into the relations of theoretical science/construction of machines as well. However, to prove our epistemological thesis, we will also exploit examples of machines built in other historical periods. Particularly, a discussion concerning the relationship between science theory and the development of science art crafts produced by non-recognized scientists in a certain historical time is presented. The main questions are: when and why did the tension between science (physics, mathematics and geometry give rise to a new scientific approach to applied discipline such as studies on machines and machineries? What kind of science was used (if at all for projecting machines and machineries? Was science at the time a necessary precondition to build a machine? In the first part we will focus on the difference between Aristotelian-Euclidean and Archimedean approaches and we will outline the heritage of these two different approaches in late medieval and Renaissance science. In the second part, we will apply our reconstructions to some historical and epistemological

    Whenever individuals adapt their jobs to make them closer of their personal preferences, they are performing job crafting. This study aims to investigate if the way nurses perceive their leaders' behaviors is related with job crafting development. To do so, a quantitative analysis was conducted among a group of 325 Portuguese nurses. Results indicate that the perception of an empowering leader was found to be strongly related with the increase of challenges in the work environment, and with the development of stronger relations with direct managers and co-workers, which are two job crafting dimensions. The perception of a directive leader was found to be positively related with the avoidance of performing hindering tasks. Strengthening relations with direct managers and co-workers was found to be particularly related to leadership perception. Theoretical and practical implications are discussed.

  6. Developing construction labor through modular training

    International Nuclear Information System (INIS)

    Moody, J.R.; Amos, T.M. Jr.

    1976-01-01

    Traditionally, the construction industry has depended on apprenticeship, technical and vocational schools, and experience through informal on-the-job training to meet the industry's demands for skilled manpower. However, as increasingly larger heavy construction projects, such as nuclear power plants, have come to demand more and more skilled craftsmen, the traditional methods of developing construction labor have become insufficient both in terms of the number of workers made available and in the quality of their skills. Over the past eight years, Brown and Root, Inc., has developed a task oriented modular system for training construction workers which supplements a worker's on-the-job training and decreases the time it requires the individual to become a productive member of the project workforce in his work. This training approach is not a series of the semester-long courses which have typified apprenticeship and vocational training in the past, but a systems approach to designing and implementing a program of classroom modules for craft development programs which emphasize both the hands-on tasks a construction worker must perform in his craft as well as the related theory required. The system consists of a number of modular courses which can be sequenced, for each craft, to develop construction skills in each worker according to both his needs and the needs of the project. The training modules for a particular craft program are developed utilizing Instructional Systems Development (ISD). This process is divided into five major phases: analysis, establishment of objectives, preparation of tests, planning and developing instructional content, and evaluation

    2014-04-01

    Full Text Available Equipment availability is necessary in the development of Agriculture mechanization. Crop thinning is one of the most important stages in row crop production which is laborious and costly. The objective of this project is design and construction of a row crop thinning machine. Four main system units are plant sensors, ground sensors, control and thinning platforms. In this machine the unwanted plants on the rows are randomly removed by employing a pneumatically system. A blade on a vertical arm with pendulum motion removes the plant from the rows. The machine control system consists of an arm and a blade which is activated by a double acting cylinder and equipped with a relay and a timer. The pneumatic cylinder is controlled via a solenoid valve. Laboratory tests were conducted to validate the machine performance. Some other preliminary tests also were performed for optimization of parameters such as cinematic index and cutting length of blades. The laboratory tests (totally 9 tests were performed with a constant forward speed and three levels of plant density, using artificial plants. The data were analyzed using SPSS software. The results show that satisfactory performance of the machine is achieved when the plant density is moderate i.e. the thinning performance reduces with higher plant distance in the row. The other effective variable on machine performance is the adjustment of sensor sensitivity, which is used to distinguish between week and strong plants. In general the machine performance is sensitive to plant shape and morphology, plant distribution pattern in the field, growing stage of the plants, time of thinning and the effectiveness of previous weeding operations

  9. The meanings of craft to an occupational therapist.

    Science.gov (United States)

    Harris, Emma

    2008-06-01

    Craft was the first therapeutic occupation of occupational therapy. Since the early days of the profession, the value of craft in practice is a topic that has been discussed with fluctuating interest. Recent discussions by occupational therapists have reinforced that although craft is relevant to occupational therapy, there are uncertainties about its place in contemporary practice. Presently, scholars have identified that occupation is both the center of human experience and the core of our profession. Therefore, this study aimed to begin to clarify the meaning of craft to practice today by gaining a deep understanding of the meanings that one occupational therapist attributes to craft. Using narrative inquiry, data were gathered through a conversation held between the research participant and myself. A reflexive journal was also kept to support this data gathering process. Narrative analysis enabled intimate engagement with the data and the emergence of themes and sub-themes. The findings, in the form of an interpretive story, suggest first, that craft-making has therapeutic value; second, that reasoning about the therapeutic use of craft is similar to reasoning about other therapeutic activities; and third, that personal experience with craft-making can influence the selection of craft as therapeutic media. From this study, further research into the impact personal and professional experiences can have on choice of therapeutic media and an analysis of the sociopolitical context of the meanings that occupational therapists attribute to craft-making is suggested.

    Antti Hilmola

    2016-06-01

    Full Text Available In this research project, the validity of the school assessment is examined in the craft subject in Finland’s basic education. The criteria for the school assessment are based on the Finnish Na-tional Core Curriculum (FNCC in which the idea of the Entire Craft (EC is highlighted. How-ever, the discussion as to whether or not the school practice is based on the idea of EC, or whether the teachers are still focused on the technical details of products in reflecting on the pupils’ tool-handling skills, is still an ongoing debate. Learner-centred learning is implicated in EC since the pupils are expected to set goals for the implementation of their own ideating, plan-ning and constructing. And, finally, in such a process, the self-reflection of the implemented out-comes against the goals will take place.  Altogether 73 craft teachers from 59 upper level schools participated in this research project. The pupils’ (N = 982 success was assessed during an EC period using the indicator validated by the previous nation-wide evaluation by the Finn-ish National Board of Education (FNBE. Since the valid school assessment was expected to reflect the success in the Entire Craft Assessment Period (ECAP, the outcomes were assessed against the criteria of the FNCC and compared to the pupils’ school scores. The data was ana-lysed using the Linear Regression Analysis (Enter Method. The central observation was that the pupils’ success in the criteria of the EC do not reflect the 7th grade school scores, in all re-spects. Moreover, the pupils’ success does not reflect the 6th grade school scores. The instruc-tions and supplementary education of the FNCC criteria are needed for craft teachers, especial-ly for class teachers at the lower level. In Finland, also the craft subject is taught by the class teachers at the lower level while, at the upper level, the subject teachers take their place. Ac-cording to the new FNCC, the number of class lessons will be

  2. Deep Visual Attributes vs. Hand-Crafted Audio Features on Multidomain Speech Emotion Recognition

    Directory of Open Access Journals (Sweden)

    Michalis Papakostas

    2017-06-01

    Full Text Available Emotion recognition from speech may play a crucial role in many applications related to human–computer interaction or understanding the affective state of users in certain tasks, where other modalities such as video or physiological parameters are unavailable. In general, a human’s emotions may be recognized using several modalities such as analyzing facial expressions, speech, physiological parameters (e.g., electroencephalograms, electrocardiograms etc. However, measuring of these modalities may be difficult, obtrusive or require expensive hardware. In that context, speech may be the best alternative modality in many practical applications. In this work we present an approach that uses a Convolutional Neural Network (CNN functioning as a visual feature extractor and trained using raw speech information. In contrast to traditional machine learning approaches, CNNs are responsible for identifying the important features of the input thus, making the need of hand-crafted feature engineering optional in many tasks. In this paper no extra features are required other than the spectrogram representations and hand-crafted features were only extracted for validation purposes of our method. Moreover, it does not require any linguistic model and is not specific to any particular language. We compare the proposed approach using cross-language datasets and demonstrate that it is able to provide superior results vs. traditional ones that use hand-crafted features.

  13. The craft of intensive care medicine.

    Science.gov (United States)

    Carmel, Simon

    2013-06-01

    The practice of medicine is often represented as a dualism: is medicine a 'science' or an 'art'? This dualism has been long-lasting, with evident appeal for the medical profession. It also appears to have been rhetorically powerful, for example in enabling clinicians to resist the encroachment of 'scientific' evidence-based medicine into core areas of medical work such as individual clinical judgement. In this article I want to make the case for a more valid conceptualisation of medical practice: that it is a 'craft' activity. The case I make is founded on a theoretical synthesis of the concept of craft, combined with an analysis of ethnographic observations of routine medical practice in intensive care. For this context the craft aspects of medical work can be seen in how biomedical and other types of knowledge are used in practice, the embodied skills and practical judgement of practitioners and the technological and material environment. These aspects are brought together in two conceptual dimensions for 'craft': first, the application of knowledge; second, interaction with the material world. Some practical and political implications of a 'craft' metaphor for medical practice are noted. © 2013 The Author.

    This paper describes an attempt on a construction way of human friendly man-machine interface. At first, we do a simple experiment to find out the characteristic of human verbal communication. From the experimental results, we get some rules in case in human verbal communication. We construct the man-machine interface which is based on these rules. Through teaching process, we examine our verbal communication interface comparing with conventional interfaces. From this comparison, we recognize that the verbal communication interface is valid to construct the user-friendly man-machine interface. 12 refs., 9 figs., 2 tabs.

    2018-01-01

    The main objective is to study the effects of job crafting activities of elder care and nursing home employees on their perceived well-being and quality of care in two European countries, Spain and Sweden. The Job Crafting, the General Health, and the Quality of Care questionnaires were administered to 530 employees. Correlations and hierarchical regression analyses were performed. Results confirm the effects of job crafting on quality of care ( r = .291, p employees' well-being ( r = .201, p well-being in Spain and Sweden and with quality of care in Spain. On the contrary, in Sweden, the relationship between job crafting and well-being was not linear. Job crafting contributes significantly to employees' and residents' well-being. Management should promote job crafting to co-create meaningful and productive work. Cultural effects are proposed to explain the differences found.

    The EVA (extravehicular activity) project forming part of the space construction process is reviewed. The manual EVA constuction, demonstrated by the crew of Skylab 3 by assembling a modest space structure in the form of the twin-pole sunshade, is considered, indicating that the experiment dispelled many doubts about man's ability to execute routine and contingency EVA operations. Tests demonstrating the feasibility of remote teleoperator rendezvous, station keeping, and docking operations, using hand controllers for direct input and television for feedback, are noted. Future plans for designing space construction machines are mentioned.

    2017-12-01

    Indonesia has plenty of abundant natural wealth. This natural wealth produces natural materials that can be utilized as a craft product. The craft workers generally still work manually and the work is done repeatedly in one cycle so it is very susceptible to musculoskeletal disorders. Musculoskeletal disorders will cause decrease of worker’s effectiveness and efficiency in completing the task. Thus, this fact has some adverse impact for the company. The purpose of this study is to analyze some task in manufacturing a traditional cooking tool (griddle) which encompasses mold of the griddle, refine of the griddle and the finishing touch by using the Occupational Repetitive Action Index (OCRA index) method. This method consists of high frequency movements, large forces, awkward postures, insufficient resting time and other factor such as vibration. Result of this study shows that in the molding operation, the worker has uncertain and medium risk on right hand in manufacturing small and large size of griddle with OCRA index is 2.5 and 5.3 respectively. In the refining operation the worker has light and medium risk on left hand in manufacturing small and large size with OCRA index is 3.6 and 5.8 using grinding machine and 5.8, 5.2, 6.3 and 5.0 using miser tool. In finishing operation, the worker has high risk on right hand in numbering of code griddle and has medium risk on right hand and medium on left hand in labeling with OCRA index is 9, 6.1 and 6.8 While in assembling operation the worker has no risk. Score that it indicates the risk level of the task in such job. Thus the following actions are to improve the work condition ergonomicly in all operation in alumunium craft.

  7. Diverse orientations in craft education: Student teachers’ conceptions and perceptions

    2016-03-01

    Full Text Available Craft education in Finland has been in a state of change. The concept of a holistic craft process was implemented in the National Core Curriculum in 2004 and the new Curriculum from 2014 strengthened it. Craft and holistic craft is not one unity but includes several orientations. This study aims to research student teachers’ conceptions and perceptions about diverse orientations and the necessity of craft education before they begin their studies in craft pedagogy. Given that the beliefs that student teachers bring to professional learning play a pivotal role in influencing what they can learn from teacher education, they are a subject worthy of investigation. The data consists of on‐line questionnaire answers by student teachers (N=113 at the University of Finland in teacher education in 2014. The on-line questionnaire was answered at the beginning of a basic course in textile craft education at an early stage of their teacher studies. Findings suggest that student teachers conceive of craft education primarily as model-oriented and skill-oriented rather than design-oriented and expression-oriented. Student teachers think that craft education is needed at school, but explanations are not very diverse. The findings of this study can be useful in the process of developing teacher education programmes.

  14. Self-crafting vegetable snacks: testing the IKEA-effect in children.

    Science.gov (United States)

    Raghoebar, Sanne; van Kleef, Ellen; de Vet, Emely

    2017-01-01

    The purpose of this paper is to test whether the IKEA-effect (Norton et al. , 2012) - better liking for self-crafted products than for identical products crafted by others - can be exploited to increase liking and consumption of vegetable snacks in children. A between-subjects experiment was conducted at an after school care facility. In total, 86 children aged four to six either crafted a peacock with vegetables or with non-food objects following an example. After the task, children ate snack vegetables ad libitum, and rated their liking for the vegetables and pride in crafting the peacock. No significant main effect of the vegetable snack creation on consumption and liking was observed. Also, perceived pride did not mediate the effect of self-crafting vegetable snacks on consumption of and liking for vegetables. Vegetable consumption did not differ between children who were either simply exposed to vegetable snacks while crafting or those who were crafting the vegetable snacks themselves. The equal consumption might suggest that this is caused by simple exposure, but more research is needed comparing self-crafting and exposure to a condition where there is no initial exposure to vegetables. Although the IKEA-effect has been demonstrated in adults, this is one of the first studies evaluating the IKEA-effect in children and as a means to increase liking for a generally disliked product in this target group, i.e. vegetables. The IKEA-effect could not be replicated under these more stringent conditions, where the experimental set-up enabled disentangling exposure and crafting effects.

    Raja, Erum K.; DeSchepper, Daniel J.; Nilsson Lill, Sten O.; Klumpp, Douglas A.

    2012-01-01

    Friedel-Crafts acylation has been known since the 1870s and it is an important organic synthetic reaction leading to aromatic ketone products. Friedel-Crafts acylation is usually done with carboxylic acid chlorides or anhydrides while amides are generally not useful substrates in these reactions. Despite being the least reactive carboxylic acid derivative, we have found a series of amides capable of providing aromatic ketones in good yields (55–96%, 17 examples). We propose a mechanism involving diminished C-N resonance through superelectrophilic activation and subsequent cleavage to acyl cations. PMID:22690740

    1979-08-01

    Substantial cost overruns and schedule delays are traits of the power plant construction industry, specifically the young and controversial nuclear power plant construction industry. These cost and schedule overruns are having a significant effect on the economic feasibility of many power plants, and the future energy supply network of our country may have to be restructured in light of these overruns. A major cause of cost overruns is related to the declining rate of productivity of workers. Marjatta Strandell, an engineering and construction expert for the Pacific Power and Light Company, Portland, Oregon, reports that since 1970 craft productivity in nuclear and fossil-fuel power plant construction has been decreasing at an average annual rate of four percent. The cumulative effect of this indicates that, by 1980, the craft productivity would be a mere sixty percent of the 1970 craft productivity

  5. Job crafting: Towards a new model of individual job redesign

    Directory of Open Access Journals (Sweden)

    Maria Tims

    2010-12-01

    Research purpose: The purpose of the study was to fit job crafting in job design theory. Motivation for the study: The study was an attempt to shed more light on the types of proactive behaviours of individual employees at work. Moreover, we explored the concept of job crafting and its antecedents and consequences. Research design, approach and method: A literature study was conducted in which the focus was first on proactive behaviour of the employee and then on job crafting. Main findings: Job crafting can be seen as a specific form of proactive behaviour in which the employee initiates changes in the level of job demands and job resources. Job crafting may be facilitated by job and individual characteristics and may enable employees to fit their jobs to their personal knowledge, skills and abilities on the one hand and to their preferences and needs on the other hand. Practical/managerial implications: Job crafting may be a good way for employees to improve their work motivation and other positive work outcomes. Employees could be encouraged to exert more influence on their job characteristics. Contribution/value-add: This article describes a relatively new perspective on active job redesign by the individual, called job crafting, which has important implications for job design theories.

  20. Craft vs. industrial: Habits, attitudes and motivations towards beer consumption in Mexico.

    Science.gov (United States)

    Gómez-Corona, Carlos; Escalona-Buendía, Héctor B; García, Mauricio; Chollet, Sylvie; Valentin, Dominique

    2016-01-01

    Food choices tend to be stable over time; they do not change fast, since consumers tend to act like creatures of habits. However, food habits can evolve, like currently the craft beer category. A change of habits involves a change of perception towards a product. Therefore, what is changing in the perception of beer? Two studies were conducted to address this question. First study was preliminary and aimed at exploring beer consumption habits in Mexico and a better understanding of craft beer representation among beer users. A questionnaire was administrated to 207 consumers in Mexico City during a beer festival. Results showed that respondents could be classified in: industrial beer (41.1%), occasional industrial (24.1%), and craft beer (34.8%) consumers. Craft cluster included mostly 25-35 years old men with high-income level. Among the craft beers cited by respondents from this cluster some are industrial, suggesting that the concept of craft beer might not be well defined, or defined in ideological terms. The second and main study was conducted using consumer ethnographies to understand the motivations and benefits of craft beer consumption. Opposite to industrial, craft beer emerges as an experience-based and symbolic product rather than a utilitarian one. The main motivation for drinking craft beer seems to be the quest of authenticity. Respondents' motivations to drink craft beer are generated by three important factors: desire for more knowledge, new taste experiences, and move away from the mainstream beer consumption. Craft consumers do not drink the product for its functional attributes, they consume it for what it means and as a consequence they build an identity, perceived as more authentic and unique, in comparison to the mainstream industrial beer consumption in Mexico.

  1. Method to Increase the Coupling Force in a Construction Machine

    Directory of Open Access Journals (Sweden)

    Tsipurskij Il’ja

    2017-01-01

    Full Text Available This paper discusses a possible method to increase the coupling tractive force track-wheel locomotion of construction machines. Sufficient tractive coupling force allows organizing translational displacement of the machine under above-medium load modes during operation of overburden chain excavators, tower cranes and gantry cranes in outdoors environments. A mechanism is examined to convert rotary motion into rectilinear motion using the example of a gear and rail, with kinematic calculations quoted. Analysis of the “force couple” system is proposed to identify free traction forces. Factors are established that influence the machine’s working movements. Equations to calculate tractive forces in track-wheel locomotion are described. A laboratory complex is presented where students of mechanical engineering gain practical skills in mastering the production process of soil excavation and the influence of the coupling tractive force during the machine’s operation. As practical recommendation, the paper describes a device made of a balancing lever, drive cogwheel and tractive chain to implement the required tractive force of the trolley in coupling; this solution’s efficiency is demonstrated for experimental works on hard soils with high coefficient of difficulty.

  2. Constructing Support Vector Machine Ensembles for Cancer Classification Based on Proteomic Profiling

    Yong Mao; Xiao-Bo Zhou; Dao-Ying Pi; You-Xian Sun

    2005-01-01

    In this study, we present a constructive algorithm for training cooperative support vector machine ensembles (CSVMEs). CSVME combines ensemble architecture design with cooperative training for individual SVMs in ensembles. Unlike most previous studies on training ensembles, CSVME puts emphasis on both accuracy and collaboration among individual SVMs in an ensemble. A group of SVMs selected on the basis of recursive classifier elimination is used in CSVME, and the number of the individual SVMs selected to construct CSVME is determined by 10-fold cross-validation. This kind of SVME has been tested on two ovarian cancer datasets previously obtained by proteomic mass spectrometry. By combining several individual SVMs, the proposed method achieves better performance than the SVME of all base SVMs.

  5. Empowering leadership and job crafting: The role of employee optimism.

    Science.gov (United States)

    Thun, Sylvi; Bakker, Arnold B

    2018-06-08

    The objective of this study was to test the relationship between empowering leadership and job crafting and to examine the moderating role of optimism as a personal resource. We hypothesized that the association between empowering leadership and job crafting would be stronger for employees with high (vs. low) levels of optimism. A total of 331 Norwegian workers from a variety of occupations participated in our study. Results of structural equation modelling analysis generally supported our hypotheses. Empowering leadership was positively related to 3 of the 4 job crafting strategies investigated (increasing structural job resources, increasing social job resources, and increasing challenging job demands; but not reducing hindrance job demands). Moreover, as hypothesized, optimism strengthened the empowering leadership-job crafting relationship for increasing structural resources and increasing challenging demands. The results suggest that empowering leadership is an important antecedent of job crafting strategies, except for reducing hindrance demands. The implications of these findings are discussed.

  10. Legal and economic implications of the German Craft Code Amendment 2004

    Directory of Open Access Journals (Sweden)

    Wolfgang Benzel

    2012-01-01

    Full Text Available As the main reason for initiating an amendment of the Trade and Crafts Code in 2004 was the decrease in the number of companies in general and the number of skilled crafts enterprises in particular and was also due to the fact that the number of employees in the skilled crafts sector had constantly fallen and many companies were not able to find a successor, it was the declared aim of the amendment to counter this structural crisis as well as reducing illegal employment and removing native discrimination. This would then ensure a higher level of employment especially through new company formations and takeovers of existing companies.In addition to providing an important contribution towards the assessment of the basic success of the 2004 Trade and Crafts Code amendment, the results can therefore be used at an international level for discussions on skilled crafts legislation outside Germany. As German skilled crafts legislation developed in a completely different manner from skilled crafts legislation in most other European countries, this aspect is particularly significant and it is conceivable that the results will be useful beyond the borders of the Federal Republic of Germany. The research findings will also be important in determining the limits of deregulation and when it can be considered counterproductive from an economic point of view.

    Bakker, Arnold B

    2018-04-01

    The aim of this study was to examine the impact of job crafting on the quality of the work environment of health care professionals. Job crafting refers to proactive behavior aimed at optimizing the fit between person and job. Using job demands-resources theory, we hypothesized that job crafting would be positively related to job resources and person-organisation fit, and negatively to hindrance demands. Furthermore, we hypothesized that these relationships would be qualified by work engagement. A total of 5,272 health care professionals from one of 35 different organisations filled out an electronic questionnaire (response is 55%). Regression analyses were used to test hypotheses. Consistent with hypotheses, job crafting in the form of increasing job resources was positively related to opportunities for development, performance feedback and P-O fit; and negatively related to hindrance job demands - particularly when work engagement was high. The combination of job crafting and work engagement is important for the realization of a resourceful work environment and fit between person and organisation. Interventions aimed at fostering job crafting should be tailored to the motivation of health care professionals. © 2017 John Wiley & Sons Ltd.

  14. “Not a Vacation, But a Hardening Process”: The Self-Empowerment Work of Therapeutic Craft in Nova Scotia

    Directory of Open Access Journals (Sweden)

    Erin Morton

    2014-10-01

    Full Text Available This article will examine the development of a state-sponsored therapeutic craft regime in Nova Scotia in the early to mid-twentieth century. Built on the notion that postwar residents needed "work therapy - not a vacation, but a hardening process" (Black n.d. a: 3 - therapeutic craft emerged in Nova Scotia through a complex combination of the individualization of work habits, the desire to construct an antimodern regional identity around handwork, and the notion that both infirm patients and the province as a whole could be healed from economic stagnation through craft. Key to the success of Nova Scotia's therapeutic craft regime was occupational therapist Mary E. Black's career as director of the provincial government's Handicrafts and Home Industries Division from 1943 to 1955. Black's healthcare training led her to seek out therapeutic possibilities in everyday work activities, not to mention a therapeutic solution to what she called "the atti-tude of most Nova Scotians"[:] defeatism" (Black 1949: 46. Her ability to turn seemingly disparate things - such as Scandinavian design, the ordered work of occupational rehabilitation, and a phenomenological focus on what she called “in-dividualistic existence” (Black n.d. b: 2 - into a unified therapeutic solution demonstrates that the contemporary rise of therapeutic culture under the increased individualism of the neoliberal era has an established historical root in the postwar period that remains important to understand.

  20. A discussion of the necessity of craft education in the 21st century

    Directory of Open Access Journals (Sweden)

    Eva Veeber

    2015-02-01

    Full Text Available Craft education has held a permanent place in Estonian and Finnish schools, although its value and appreciation have changed over time. The aim of the article is to discuss the necessity of craft education in today’s world and its possible impact on the development of children and adolescents. The discussion seeks an interdisciplinary explanation using three perspectives that complement each other. The first describes the challenges of modern society with respect to individual development and schooling. The second deals with Aaron Antonovsky's theory of generalized resistance resources and an individual's possibility to manage in a stressful society. The third addresses the individual as a developing neurological being, along with the effect of learning and practicing motor skills on the human brain. We conclude that crafts is a multidisciplinary phenomenon, and that learning and practicing crafts promotes the comprehension of diversity and challenges in life. Additionally, educational crafts enriches the learning environment, offering opportunities to develop transferable skills that human beings constantly need in society. In addition, crafts provides a balanced way to come to understand the world and one’s role in it, by simultaneously promoting motor and cognitive development and making unique demands on one’s being.Keywords: crafts, craft education, making, sense of coherence, education, embodiment

    This longitudinal study examined whether employees can impact their own well-being by crafting their job demands and resources. Based on the job demands-resources model, we hypothesized that employee job crafting would have an impact on work engagement, job satisfaction, and burnout through changes in job demands and job resources. Data was collected in a chemical plant at three time points with one month in between the measurement waves (N = 288). The results of structural equation modeling showed that employees who crafted their job resources in the first month of the study showed an increase in their structural and social resources over the course of the study (2 months). This increase in job resources was positively related to employee well-being (increased engagement and job satisfaction, and decreased burnout). Crafting job demands did not result in a change in job demands, but results revealed direct effects of crafting challenging demands on increases in well-being. We conclude that employee job crafting has a positive impact on well-being and that employees therefore should be offered opportunities to craft their own jobs.

    The intention to leave surgical training, hereinafter referred as proxy of "attrition," is associated with poor well-being in the workplace. Attrition is suggested to diminish when residents possess job-crafting skills, that is, the ability to redefine their job in meaningful ways and maximize well-being at work by increasing structural and social resources and challenges and decreasing hindering demands. However, the evidence supporting this relationship is scant. This study sought to: 1) investigate to what extent residents possess job-crafting skills and compare residents' levels of job-crafting skills across years of residency training; 2) investigate the relationship between job crafting, well-being as measured by burnout and work-engagement rates, and the intention to leave; and 3) compare the levels of job-crafting skills and well-being between residents with and without serious intentions to leave. This cross sectional study was conducted in fifteen residency programs in Colombia. Surgical residents completed different questionnaires including the Dutch Job Crafting Scale (DJCS), MBI-Human Services Survey (MBI-HSS), Utrecht Work Engagement Scale (UWES-17) and an adapted version of the Nurse Turnover Intention Scale (NTIS). The objectives were addressed by independent analyses of variance (ANOVA), structural equation modeling techniques (SEM) and independent t-tests, respectively. A total of 202 residents participated. Residents generally scored high on their job-crafting skills to increase structural and social resources as well as challenging demands, but were less positive about their skills to reduce hindering demands. No differences across years of training were found. Job crafting correlated positively with work-engagement, which was inversely related to the intention to leave. Conversely, job crafting correlated negatively with burnout, which bore a positive relationship to the intention to leave. Residents with serious intentions to leave exhibited

    The present study aims to uncover the way daily job crafting influences daily job performance (i.e., task performance, altruism, and counterproductive work behavior). Job crafting was conceptualized as "seeking resources," "seeking challenges," and "reducing demands" and viewed as strategies individuals use to optimize their job characteristics. We hypothesized that daily job crafting relates to daily job demands and resources (work pressure and autonomy), which consequently relate to daily work engagement and exhaustion and ultimately to job performance. A sample of 95 employees filled in a quantitative diary for 5 consecutive working days (n occasions = 475). We predicted and found that daily seeking resources was positively associated with daily task performance because daily autonomy and work engagement increased. In contrast, daily reducing demands was detrimental for daily task performance and altruism, because employees lower their daily workload and consequently their engagement and exhaustion, respectively. Only daily seeking challenges was positively (rather than negatively) associated with daily counterproductive behavior. We conclude that employee job crafting can have both beneficial and detrimental effects on job performance. (c) 2015 APA, all rights reserved).

    Evidence-based practice (EBP) is a model of clinical decision-making that is increasingly being advocated for use in the field of speech-language pathology. With the increased emphasis on scientific evidence as a form of knowledge important to EBP, clinicians may wonder whether their craft-based knowledge (i.e., knowledge derived from theory and practice), remains a legitimate form of knowledge for use in clinician decisions. This article describes forms of knowledge that may be used to address clinical questions, to include both craft and science. Additionally, the steps used when engaging in EBP are described so that clinicians understand when and how craft comes into play. The major premise addressed within this article is that craft is a legitimate form of knowledge and that engagement in EBP requires one to employ craft-based knowledge.

    Manually annotated corpora are critical for the training and evaluation of automated methods to identify concepts in biomedical text. This paper presents the concept annotations of the Colorado Richly Annotated Full-Text (CRAFT) Corpus, a collection of 97 full-length, open-access biomedical journal articles that have been annotated both semantically and syntactically to serve as a research resource for the biomedical natural-language-processing (NLP) community. CRAFT identifies all mentions of nearly all concepts from nine prominent biomedical ontologies and terminologies: the Cell Type Ontology, the Chemical Entities of Biological Interest ontology, the NCBI Taxonomy, the Protein Ontology, the Sequence Ontology, the entries of the Entrez Gene database, and the three subontologies of the Gene Ontology. The first public release includes the annotations for 67 of the 97 articles, reserving two sets of 15 articles for future text-mining competitions (after which these too will be released). Concept annotations were created based on a single set of guidelines, which has enabled us to achieve consistently high interannotator agreement. As the initial 67-article release contains more than 560,000 tokens (and the full set more than 790,000 tokens), our corpus is among the largest gold-standard annotated biomedical corpora. Unlike most others, the journal articles that comprise the corpus are drawn from diverse biomedical disciplines and are marked up in their entirety. Additionally, with a concept-annotation count of nearly 100,000 in the 67-article subset (and more than 140,000 in the full collection), the scale of conceptual markup is also among the largest of comparable corpora. The concept annotations of the CRAFT Corpus have the potential to significantly advance biomedical text mining by providing a high-quality gold standard for NLP systems. The corpus, annotation guidelines, and other associated resources are freely available at http://bionlp-corpora.sourceforge.net/CRAFT/index.shtml.

    Research and development starting in 1984 of electron beam technology in Indonesia is first briefly presented. BATAN assigned to the Yogyakarta Nuclear Center the project of constructing an electron beam machine of 350 keV/10 mA for multipurpose applications especially for thin samples for duration of five years. The main objective of the project was the young scientists training and demonstration purposes in operation and maintenance of the machine. The engineers have learned through experience of the low energy ion accelerator (150 kV) many techniques to construct the system component such as E-gun, high voltage, vacuum, beam optics, scanning horn and window, beam stopper, and conveyer as well as the embedded control system. Because of the window cooling system, the uses of the machine are limited for irradiating a thin sample of plastics, hydrogel, powder, or liquid. Future plans for modification of the machine are stated. (S. Ohno)

  19. Historical and Epistemological Reflections on the Culture of Machines around the Renaissance: Machines, Machineries and Perpetual Motion

    2015-05-01

    Full Text Available This paper is the second part of our recent paper ‘Historical and Epistemological Reflections on the Culture of Machines around the Renaissance: How Science and Technique Work’ (Pisano & Bussotti 2014a. In the first paper—which discussed some aspects of the relations between science and technology from Antiquity to the Renaissance—we highlighted the differences between the Aristotelian/Euclidean tradition and the Archimedean tradition. We also pointed out the way in which the two traditions were perceived around the Renaissance. The Archimedean tradition is connected with machines: its relationship with science and construction of machines should be made clear. It is enough to think that Archimedes mainly dealt with three machines: lever, pulley and screw (and a correlated principle of mechanical advantage. As underlined in the first part, our thesis is that many machines were constructed by people who ignored theory, even though, in other cases, the knowledge of the Archimedean tradition was a precious help in order to build machines. Hence, an a priori idea as to the relations between the Archimedean tradition and construction of machines cannot exist. In this second part we offer some examples of functioning machines constructed by people who ignored any physical theory, whereas, in other cases, the ignorance of some principles—such as the impossibility of a perpetuum mobile—induced the attempt to construct impossible machines. What is very interesting is that these machines did not function, of course, as a perpetuum mobile, but anyway had their functioning and were useful for certain aims, although they were constructed on an idea which is completely wrong from a theoretical point of view. We mainly focus on the Renaissance and early modern period, but we also provide examples of machines built before and after this period. We have followed a chronological order in both parts, starting from the analysis of the situation in

  4. Two-craft Coulomb formation study about circular orbits and libration points

    Science.gov (United States)

    Inampudi, Ravi Kishore

    This dissertation investigates the dynamics and control of a two-craft Coulomb formation in circular orbits and at libration points; it addresses relative equilibria, stability and optimal reconfigurations of such formations. The relative equilibria of a two-craft tether formation connected by line-of-sight elastic forces moving in circular orbits and at libration points are investigated. In circular Earth orbits and Earth-Moon libration points, the radial, along-track, and orbit normal great circle equilibria conditions are found. An example of modeling the tether force using Coulomb force is discussed. Furthermore, the non-great-circle equilibria conditions for a two-spacecraft tether structure in circular Earth orbit and at collinear libration points are developed. Then the linearized dynamics and stability analysis of a 2-craft Coulomb formation at Earth-Moon libration points are studied. For orbit-radial equilibrium, Coulomb forces control the relative distance between the two satellites. The gravity gradient torques on the formation due to the two planets help stabilize the formation. Similar analysis is performed for along-track and orbit-normal relative equilibrium configurations. Where necessary, the craft use a hybrid thrusting-electrostatic actuation system. The two-craft dynamics at the libration points provide a general framework with circular Earth orbit dynamics forming a special case. In the presence of differential solar drag perturbations, a Lyapunov feedback controller is designed to stabilize a radial equilibrium, two-craft Coulomb formation at collinear libration points. The second part of the thesis investigates optimal reconfigurations of two-craft Coulomb formations in circular Earth orbits by applying nonlinear optimal control techniques. The objective of these reconfigurations is to maneuver the two-craft formation between two charged equilibria configurations. The reconfiguration of spacecraft is posed as an optimization problem using the

    2016-09-01

    Full Text Available Orientation: Job crafting can result in a number of positive outcomes for teachers, such as increased meaningfulness and engagement at work. Increased work engagement and psychological meaningfulness may yield positive benefits for the practice of teaching, thus highlighting the pivotal role of job crafting. Research purpose: The study’s aim was to investigate the relationship between job crafting and subjective well-being amongst South African high school teachers. Subjective well-being comprises psychological meaningfulness and work engagement. The potential mediating effect that psychological meaningfulness had on this relationship was further explored. Motivation for the study: Being in a highly stressful occupation, teachers need to continuously find ways to craft their working practices in order to deal effectively with their job demands and to capitalise on their available job resources. Furthermore, South Africa’s current education system calls for serious proactive measures to be taken to improve and rectify the current status, such as job crafting. Research approach, design and method: A quantitative, cross-sectional survey design was used and administered to a sample of South African high school teachers situated in Gauteng, South Africa (N = 251. Main findings: A positive relationship was found between job crafting (increasing structural resources and challenging job demands and work engagement. Furthermore, psychological meaningfulness mediated the relationship between job crafting and work engagement amongst the sampled high school teachers. Practical/managerial implications: Teachers who craft their work to better suit their preferences and needs will obtain greater meaning in their work and experience increased levels of work engagement. Training programmes and/or group-based interventions targeted around job crafting techniques may be particularly useful in the South African teaching context. Contribution/value-add: This

  8. Primary student teachers’ perceptions of their prior experiences with craft-making in light of Hannah Arendt’s human condition

    Seija Karppinen

    2013-09-01

    Full Text Available This article presents the results of a study about student teachers’ feelings toward craft-making and teaching crafts. As a teacher educator in teacher training, my interest lies first in student teachers’ prior craft experiences and in their prejudices about themselves as craft-makers in relation to the human condition as set forth by philosopher Hannah Arendt (1958/2002. Second, I am interested in how students’ experiences and their image of crafts affect their attitude to crafts and teaching crafts. The study uses qualitative content analysis (e.g. Cohen, Manion & Morrison, 2007, concept clarification (e.g. Kramer, 1993; Burkin, 2011 and thought experiments (Zalta, 2011; Cohnitz, 2006; Sorensen, 1992 to identify and categorise student teachers’ emotional experiences. The data consist of essays (craft biographies, N=144 by first-year student teachers which were written in 2008 and 2009 during a basic course in crafts as part of teacher education at the University of Helsinki. Arendt (1958/2002 labelled the elements of the human condition as labour, work and action. In this study I discuss how, for instance, Arendtian concepts could be explained in relation to crafts, craft-making and education. Arendt categorises craft, defined as things made by hand, as part of the concept of work. In this study, I consider whether crafts and craft-making could be part of other Arendtian terms as well and how these terms fit various educational situations. As a result, there is a need for additional terms alongside Arendtian terms to describe multifaceted craft-making and primary student teachers’ perceptions of themselves as craft-makers. In relation to student teachers’ memories on primary school crafts, I have labelled Arendtian concept labour as students’ credit-orientated activity, the concept of work as making-orientated activity and the concept of action as interaction-orientated activity. These three orientations of craft frame student

    Community Reinforcement and Family Training (CRAFT) assists family members with a treatment-resistant loved one. The most consistent outcome of CRAFT is increased treatment entry of the identified treatment-resistant person (IP). This led us to question whether all 6 components of CRAFT are necessary. In a randomized clinical trial, 115 concerned significant others (CSOs) of an IP received 12-14 sessions of the full CRAFT intervention, 4-6 sessions focused on Treatment Entry Training (TEnT), or 12-14 sessions of Al-Anon/Nar-Anon Facilitation (ANF). We monitored treatment entry, attendance, and substance use of the IP and the CSO's mood and functioning. Data were collected at baseline and 4, 6, and 9 months after the baseline. We found significant reductions in time to treatment entry (χ(2)2 = 8.89, p = .01) and greater treatment entry rates for CRAFT (62%; odds ratio [OR] = 2.7, 95% confidence interval [CI] = 1.1-6.9) and TEnT (63%; OR = 2.9, 95% CI = 1.2-7.5) compared with ANF (37%), but CRAFT and TEnT did not differ significantly from each other (OR = 1.1, 95% CI = 0.4-2.7). No between-group differences in IP drug use were reported by CSOs, but days of drug use decreased over time for all groups (F(3, 277) = 13.47, p CRAFT produces greater treatment entry rates than ANF and found similar treatment entry rates for CRAFT and TEnT. This suggests that treatment entry training is sufficient for producing the best established outcome of CRAFT. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  12. High Job Demands, Still Engaged and Not Burned Out? The Role of Job Crafting.

    2017-08-01

    Traditionally, employee well-being has been considered as resulting from decent working conditions arranged by the organization. Much less is known about whether employees themselves can make self-initiated changes to their work, i.e., craft their jobs, in order to stay well, even in highly demanding work situations. The aim of this study was to use the job demands-resources (JD-R model) to investigate whether job crafting buffers the negative impacts of four types of job demands (workload, emotional dissonance, work contents, and physical demands) on burnout and work engagement. A questionnaire study was designed to examine the buffering role of job crafting among 470 Finnish dentists. All in all, 11 out of 16 possible interaction effects of job demands and job crafting on employee well-being were significant. Job crafting particularly buffered the negative effects of job demands on burnout (7/8 significant interactions) and to a somewhat lesser extent also on work engagement (4/8 significant interactions). Applying job crafting techniques appeared to be particularly effective in mitigating the negative effects of quantitative workload (4/4 significant interactions). By demonstrating that job crafting can also buffer the negative impacts of high job demands on employee well-being, this study contributed to the JD-R model as it suggests that job crafting may even be possible under high work demands, and not only in resourceful jobs, as most previous studies have indicated. In addition to the top-down initiatives for improving employee well-being, bottom-up approaches such as job crafting may also be efficient in preventing burnout and enhancing work engagement.

    Multilevel linguistic features have been proposed for discourse analysis, but there have been few applications of multilevel linguistic features to readability models and also few validations of such models. Most traditional readability formulae are based on generalized linear models (GLMs; e.g., discriminant analysis and multiple regression), but these models have to comply with certain statistical assumptions about data properties and include all of the data in formulae construction without pruning the outliers in advance. The use of such readability formulae tends to produce a low text classification accuracy, while using a support vector machine (SVM) in machine learning can enhance the classification outcome. The present study constructed readability models by integrating multilevel linguistic features with SVM, which is more appropriate for text classification. Taking the Chinese language as an example, this study developed 31 linguistic features as the predicting variables at the word, semantic, syntax, and cohesion levels, with grade levels of texts as the criterion variable. The study compared four types of readability models by integrating unilevel and multilevel linguistic features with GLMs and an SVM. The results indicate that adopting a multilevel approach in readability analysis provides a better representation of the complexities of both texts and the reading comprehension process.

    The data for this study were collected at six nuclear power plant construction sites spread throughout the United States. The geographical distribution included two projects from the Midwest and one site from each the Deep South, North Central, Southwest, and Northeast regions of the nation. The range for stage of completion varied from between approximately four and seventy-seven percent. Two of the projects were utilizing boiling water reactors (BWR) while the balance of the sites made use of the pressurized water reactor (PWR) systems. All of the installations had generating capacities approximately equal to 1200 megawatts per unit. The primary objective of the study was to provide a comprehensive investigation of the most influential factors adversely affecting craft productivity by means of a sampling comprised of five hundred seventy-six union and open shop carpenters, electricians, and pipefitters. The overall average amount of time lost due to delays obtaining materials and tools, overcrowded working conditions, interferences between crews, postponements relating to quality control inspections, and waiting for and/or receiving instructions was estimated by the tradesmen to be 24.12 manhours per individual on a weekly basis. Thus, a minimum of 60.3% of each tradesman's time is lost due to one of the aforementioned predicaments. Conversely, this figure accounts for a maximum possible level of direct work activity equal to 39.7% and is not inclusive of any personal breaks or late starts/early quits. The combined mean duration that was speculated for rework activities at all six sites totaled 5.77 manhours per craftsman per week. The summation of these two estimates yields a value of 29.89 manhours showing that only slightly more than twenty-five percent of each worker's time is allocated to productive endeavors for activities being engaged in for the first time

    Condition monitoring and predicting of CNC machine tools are investigated in this paper. Considering the CNC machine tools are often small numbers of samples, a condition predicting method for CNC machine tools based on support vector machines (SVMs) is proposed, then one-step and multi-step condition prediction models are constructed. The support vector machines prediction models are used to predict the trends of working condition of a certain type of CNC worm wheel and gear grinding machine by applying sequence data of vibration signal, which is collected during machine processing. And the relationship between different eigenvalue in CNC vibration signal and machining quality is discussed. The test result shows that the trend of vibration signal Peak-to-peak value in surface normal direction is most relevant to the trend of surface roughness value. In trends prediction of working condition, support vector machine has higher prediction accuracy both in the short term ('One-step') and long term (multi-step) prediction compared to autoregressive (AR) model and the RBF neural network. Experimental results show that it is feasible to apply support vector machine to CNC machine tool condition prediction.

    Full Text Available Orientation: The right balance between job demands and job resources are essential for employees to bring energy and enthusiasm to work. Employees who experience high-quality relationships with their supervisors may actively craft their job demands and job resources and feel more engaged. Research purpose: The current study examined the associations between leader–member exchange (LMX, job crafting and work engagement. Motivation: This study attempts to gain more insight in the associations between LMX, job crafting and work engagement. It was hypothesised that high-quality relationships with supervisors fosters work engagement because it stimulates employees to craft their jobs by increasing social and structural job resources and challenging job demands and by decreasing hindering job demands. Research approach, design and methodology: Participants (N = 402 working for a leading mail and parcels company in the Netherlands completed questionnaires measuring LMX, work engagement and job crafting. Structural equation modelling was used to examine the hypotheses. Main findings: Increasing social job resources (β = 0.01, SE = 0.00, p < 0.001 and increasing challenging job demands (β = 0.08, SE = 0.04, p < 0.05 were significant mediators in the association between LMX and work engagement. Increasing structural job resources (β = 0.00, SE = 0.00, p = 0.92 and decreasing hindering job demands (β = -0.00, SE 0.00, p = 0.09 were not significant mediators. Practical and managerial implications: Supervisors who are capable of building high-quality relationships with their employees based on trust, respect and loyalty will foster a positive, fulfilling work-related state of mind among employees because they are more willing to proactively craft a challenging and resourceful work environment. Contribution or value-add: The findings of this study showed the importance of high-quality relationships with supervisors and were unique in examining the

    Between October 1952 and February 1957, National Lead of Ohio (NLO), a primary contractor for the Atomic Energy Commission (AEC), subcontracted certain uranium machining operations to Alba Craft Laboratory, Incorporated, located at 10-14 West Rose Avenue, Oxford, Ohio. In 1992, personnel from Oak Ridge National Laboratory (ORNL) confirmed the presence of residual radioactive materials from the AEC-related operations in and around the facility in amounts exceeding the applicable Department of Energy (DOE) guidelines. Although the amount of uranium found on the property posed little health hazard if left undisturbed, the levels were sufficient to require remediation to bring radiological conditions into compliance with current guidelines, thus ensuring that the public and the environment are protected. A team from ORNL conducted a radiological verification survey of the former Alba Craft Laboratory property between December 1994 and February 1995. The survey was conducted at the request of DOE and included directly measured radiation levels, the collection and analysis of soil samples to determine concentrations of uranium and certain other radionuclides, and comparison of these data to the guidelines. This document reports the findings of this survey. The results of the independent verification survey of the former Alba Craft Laboratory property demonstrate that all contaminated areas have been remediated to radionuclide concentrations and activity levels below the applicable guideline limits set by DOE

  9. Decomposition of the compound Atwood machine

    Lopes Coelho, R.

    2017-11-01

    Non-standard solving strategies for the compound Atwood machine problem have been proposed. The present strategy is based on a very simple idea. Taking an Atwood machine and replacing one of its bodies by another Atwood machine, we have a compound machine. As this operation can be repeated, we can construct any compound Atwood machine. This rule of construction is transferred to a mathematical model, whereby the equations of motion are obtained. The only difference between the machine and its model is that instead of pulleys and bodies, we have reference frames that move solidarily with these objects. This model provides us with the accelerations in the non-inertial frames of the bodies, which we will use to obtain the equations of motion. This approach to the problem will be justified by the Lagrange method and exemplified by machines with six and eight bodies.

  10. Construction of a web-based questionnaire for longitudinal investigation of work exposure, musculoskeletal pain and performance impairments in high-performance marine craft populations.

    2017-07-20

    High-performance marine craft personnel (HPMCP) are regularly exposed to vibration and repeated shock (VRS) levels exceeding maximum limitations stated by international legislation. Whereas such exposure reportedly is detrimental to health and performance, the epidemiological data necessary to link these adverse effects causally to VRS are not available in the scientific literature, and no suitable tools for acquiring such data exist. This study therefore constructed a questionnaire for longitudinal investigations in HPMCP. A consensus panel defined content domains, identified relevant items and outlined a questionnaire. The relevance and simplicity of the questionnaire's content were then systematically assessed by expert raters in three consecutive stages, each followed by revisions. An item-level content validity index (I-CVI) was computed as the proportion of experts rating an item as relevant and simple, and a scale-level content validity index (S-CVI/Ave) as the average I-CVI across items. The thresholds for acceptable content validity were 0.78 and 0.90, respectively. Finally, a dynamic web version of the questionnaire was constructed and pilot tested over a 1-month period during a marine exercise in a study population sample of eight subjects, while accelerometers simultaneously quantified VRS exposure. Content domains were defined as work exposure, musculoskeletal pain and human performance, and items were selected to reflect these constructs. Ratings from nine experts yielded S-CVI/Ave of 0.97 and 1.00 for relevance and simplicity, respectively, and the pilot test suggested that responses were sensitive to change in acceleration and that the questionnaire, following some adjustments, was feasible for its intended purpose. A dynamic web-based questionnaire for longitudinal survey of key variables in HPMCP was constructed. Expert ratings supported that the questionnaire content is relevant, simple and sufficiently comprehensive, and the pilot test suggested

    Potential maximum radiation dose rates were calculated for the former Alba Craft Laboratory site in Oxford, Ohio, which was involved in machining of uranium metal in the 1950s for the U.S. atomic energy program. The site is not currently being used. The residual radioactive material guidelines (RESRAD) computer code, which implements the methodology described in the US Department of Energy's (DOE's) manual for establishing residual radioactive material guidelines, was sued in this evaluation. Three potential land use scenarios were considered for the former Alba Craft site; the scenarios vary with regard to the type of site use, time spent at the site by the exposed individual, and sources of food consumed. Scenario A (a possible land use scenario) assumed industrial use of the site; Scenario B (a likely future land use scenario) assumed residential use of the site; and Scenario C (a possible but unlikely land use scenario) assumed the presence of a resident farmer. For scenario A, it was assumed that any water used for domestic or industrial activities would be from uncontaminated off-site municipal sources. The water used for drinking, household purposes, and irrigation was assumed to be from uncontaminated municipal sources in Scenario B; groundwater drawn from a well located at the downgradient edge of the contaminated zone would be the only source of water for drinking, irrigation, and raising livestock in Scenario C. The results of the evaluation indicated that the DOE dose limit of 100 mrem/yr would not be exceeded for any of the scenarios analyzed. The potential maximum dose rates for Scenarios A, B, and C are 0.64, 2.0, and 11 mrem/yr, respectively

    The base sequence in nucleic acids encodes substantial structural and functional information into the biopolymer. This encoded information provides the basis for the tailoring and assembly of DNA machines. A DNA machine is defined as a molecular device that exhibits the following fundamental features. (1) It performs a fuel-driven mechanical process that mimics macroscopic machines. (2) The mechanical process requires an energy input, "fuel." (3) The mechanical operation is accompanied by an energy consumption process that leads to "waste products." (4) The cyclic operation of the DNA devices, involves the use of "fuel" and "anti-fuel" ingredients. A variety of DNA-based machines are described, including the construction of "tweezers," "walkers," "robots," "cranes," "transporters," "springs," "gears," and interlocked cyclic DNA structures acting as reconfigurable catenanes, rotaxanes, and rotors. Different "fuels", such as nucleic acid strands, pH (H⁺/OH⁻), metal ions, and light, are used to trigger the mechanical functions of the DNA devices. The operation of the devices in solution and on surfaces is described, and a variety of optical, electrical, and photoelectrochemical methods to follow the operations of the DNA machines are presented. We further address the possible applications of DNA machines and the future perspectives of molecular DNA devices. These include the application of DNA machines as functional structures for the construction of logic gates and computing, for the programmed organization of metallic nanoparticle structures and the control of plasmonic properties, and for controlling chemical transformations by DNA machines. We further discuss the future applications of DNA machines for intracellular sensing, controlling intracellular metabolic pathways, and the use of the functional nanostructures for drug delivery and medical applications.

    Job crafting, an employee-initiated job design/redesign, has become important for employees' well-being. However, most studies on the relationship between job crafting and employees' well-being have been conducted in western countries; thus, it is unclear whether job crafting can be effectively applied to Asian cultures, such as Japan, which emphasizes group harmony. The aim of this study was to examine the cross-sectional associations of self-reported job crafting with work engagement and psychological distress among employees in Japan. A questionnaire survey through the internet was conducted among all employees of a manufacturing company in Japan. We analyzed the data from 894 respondents, all employees with regular employment. Job crafting, work engagement, and psychological distress were assessed using the Japanese version of the Job Crafting Questionnaire, the Japanese version of the Utrecht Work Engagement Scale (UWES), and the Brief Job Stress Questionnaire (BJSQ), respectively. Hierarchical multiple regression showed that increasing structural job resources, social job resources, and challenging job demands was significantly and positively associated with work engagement ( β  = 0.31, p  engagement and lower psychological distress. In addition, increasing social job resources and challenging job demands are also associated with higher work engagement.

    Full Text Available This article presents and discusses approaches for exploring higher education in Art and Crafts. The concepts exploring versus research and the different foci in an insider perspective versus an outsider perspective introduces the theme. An insider perspective is said to be a useful starting point for inquiry, referring to Frayling’s trichotomy research into, research on and research through from 1993. The field of higher education in Art and Crafts education is shortly presented as comprising two main areas of knowledge: knowledge of education, and knowledge about the different subject areas within Art and Crafts. Both theory and practice are a part of these areas of knowledge. As higher education in Art and Crafts is a making profession, the most prominent challenge when exploring this today is thus said to be to develop research based knowledge on Education in Art and Crafts as a making discipline.  Two keywords are deemed to be useful in approaching this theme: Mode 2 knowledge production and transdisciplinarity. The article concludes with describing specific ways of doing this today from within the context of application. Two examples of large research projects in Scandinavia are presented as examples of such projects.

  2. Study of on-machine error identification and compensation methods for micro machine tools

    2016-01-01

    Micro machining plays an important role in the manufacturing of miniature products which are made of various materials with complex 3D shapes and tight machining tolerance. To further improve the accuracy of a micro machining process without increasing the manufacturing cost of a micro machine tool, an effective machining error measurement method and a software-based compensation method are essential. To avoid introducing additional errors caused by the re-installment of the workpiece, the measurement and compensation method should be on-machine conducted. In addition, because the contour of a miniature workpiece machined with a micro machining process is very tiny, the measurement method should be non-contact. By integrating the image re-constructive method, camera pixel correction, coordinate transformation, the error identification algorithm, and trajectory auto-correction method, a vision-based error measurement and compensation method that can on-machine inspect the micro machining errors and automatically generate an error-corrected numerical control (NC) program for error compensation was developed in this study. With the use of the Canny edge detection algorithm and camera pixel calibration, the edges of the contour of a machined workpiece were identified and used to re-construct the actual contour of the work piece. The actual contour was then mapped to the theoretical contour to identify the actual cutting points and compute the machining errors. With the use of a moving matching window and calculation of the similarity between the actual and theoretical contour, the errors between the actual cutting points and theoretical cutting points were calculated and used to correct the NC program. With the use of the error-corrected NC program, the accuracy of a micro machining process can be effectively improved. To prove the feasibility and effectiveness of the proposed methods, micro-milling experiments on a micro machine tool were conducted, and the results

    Full Text Available Introduction: Employees are regularly offered opportunities to make their work more appealing and rewarding. These opportunities might be as simple as making fine changes to their daily tasks to boost happiness and to connect with more people at vocation. Hence, an attempt is made to assess job-crafting behavior among the dental academic faculty. Materials and Methods: A cross-sectional study was conducted among dental academic faculty from five dental colleges. Job Crafting Questionnaire (JCQ was used to assess the job-crafting behavior. Mean scores were calculated for different domains of JCQ. Gender differences were analyzed using Student's “t-” test and one-way ANOVA to test the difference between different academic positions of the faculty members. Results: A total of 228 dental faculty members with a mean age of 34.43 ± 6.13 years participated in the study. The mean value of job-crafting behavior was found to be highest among female faculty (60.07 ± 8.38 and professors (61.35 ± 8.30. Male faculty scored higher in task-crafting domain and female faculty scored higher in both cognitive- and relational-crafting domains. The professors scored highest in all the three domains of job-crafting behavior as compared to that of senior lecturers and readers. Conclusion: Job crafting is an effectual workplace intervention, where employees assume an active role in shaping their work experience to enhance their job satisfaction and well-being. The overall score of job-crafting behavior was found to be highest among both professors and female faculty members. Male faculty members scored higher in task-crafting domain. With regard to individual domains, the participants scored highest in cognitive crafting followed by task and relational crafting.

  5. Application of CRAFT in two-dimensional NMR data processing.

    Science.gov (United States)

    Krishnamurthy, Krish; Sefler, Andrea M; Russell, David J

    2017-03-01

    Two-dimensional (2D) data are typically truncated in both dimensions, but invariably and severely so in the indirect dimension. These truncated FIDs and/or interferograms are extensively zero filled, and Fourier transformation of such zero-filled data is always preceded by a rapidly decaying apodization function. Hence, the frequency line width in the spectrum (at least parallel to the evolution dimension) is almost always dominated by the apodization function. Such apodization-driven line broadening in the indirect (t 1 ) dimension leads to the lack of clear resolution of cross peaks in the 2D spectrum. Time-domain analysis (i.e. extraction of frequency, amplitudes, line width, and phase parameters directly from the FID, in this case via Bayesian modeling into a tabular format) of NMR data is another approach for spectral resonance characterization and quantification. The recently published complete reduction to amplitude frequency table (CRAFT) technique converts the raw FID data (i.e. time-domain data) into a table of frequencies, amplitudes, decay rate constants, and phases. CRAFT analyses of time-domain data require minimal or no apodization prior to extraction of the four parameters. We used the CRAFT processing approach for the decimation of the interferograms and compared the results from a variety of 2D spectra against conventional processing with and without linear prediction. The results show that use of the CRAFT technique to decimate the t 1 interferograms yields much narrower spectral line width of the resonances, circumventing the loss of resolution due to apodization.

    Barely any research has been made into the implementation of sustainable principles in glass design and craft. A common tendency among students and practitioners is to consider it problematic if not impossible to develop a “truly sustainable practice”. Generally glass crafts people and glass...... designers aim to explore new aesthetic possibilities for the material and see sustainability as a hindrance for aesthetic freedom. On the contrary the field of design has strong and growing emphasis on sustainable development. Fry (2009) argues that what he defines as sustain-ability is not an end goal...... but an ongoing process of re-directing the way we design our world and thereby our future. This approach along with further research into sustainable development within the field of design and combined with material specific methodologies may reveal new possibilities for sustainable as well as aesthetic...

  12. Different types of employee well-being across time and their relationships with job crafting.

    Science.gov (United States)

    Hakanen, Jari J; Peeters, Maria C W; Schaufeli, Wilmar B

    2018-04-01

    We used and integrated the circumplex model of affect (Russell, 1980) and the conservation of resources theory (Hobfoll, 1998) to hypothesize how various types of employee well-being, which can be differentiated on theoretical grounds (i.e., work engagement, job satisfaction, burnout, and workaholism), may differently predict various job crafting behaviors (i.e., increasing structural and social resources and challenging demands, and decreasing hindering demands) and each other over time. At Time 1, we measured employee well-being, and 4 years later at Time 2, job crafting and well-being, using a large sample of Finnish dentists (N = 1,877). The results of structural equation modeling showed that (a) work engagement positively predicted both types of increasing resources and challenging demands and negatively predicted decreasing hindering demands; (b) workaholism positively predicted increasing structural resources and challenging demands; (c) burnout positively predicted decreasing hindering demands and negatively predicted increasing structural resources, whereas (d) job satisfaction did not relate to job crafting over time; and (e) work engagement positively influenced job satisfaction and negatively influenced burnout, whereas (f) workaholism predicted burnout after controlling for baseline levels. Thus, work engagement was a stronger predictor of future job crafting and other types of employee well-being than job satisfaction. Although workaholism was positively associated with job crafting, it also predicted burnout. We conclude that the relationship between job crafting and employee well-being may be more complex than assumed, because the way in which employees will craft their jobs in the future seems to depend on how they currently feel.

    The Additive Construction with Mobile Emplacement (ACME) project is developing technology to build structures on planetary surfaces using in-situ resources. The project focuses on the construction of both 2D (landing pads, roads, and structure foundations) and 3D (habitats, garages, radiation shelters, and other structures) infrastructure needs for planetary surface missions. The ACME project seeks to raise the Technology Readiness Level (TRL) of two components needed for planetary surface habitation and exploration: 3D additive construction (e.g., contour crafting), and excavation and handling technologies (to effectively and continuously produce in-situ feedstock). Additionally, the ACME project supports the research and development of new materials for planetary surface construction, with the goal of reducing the amount of material to be launched from Earth.

  4. Application of machine learning methods in big data analytics at management of contracts in the construction industry

    Directory of Open Access Journals (Sweden)

    Valpeters Marina

    2018-01-01

    Full Text Available The number of experts who realize the importance of big data continues to increase in various fields of the economy. Experts begin to use big data more frequently for the solution of their specific objectives. One of the probable big data tasks in the construction industry is the determination of the probability of contract execution at a stage of its establishment. The contract holder cannot guarantee execution of the contract. Therefore it leads to a lot of risks for the customer. This article is devoted to the applicability of machine learning methods to the task of determination of the probability of a successful contract execution. Authors try to reveal the factors influencing the possibility of contract default and then try to define the following corrective actions for a customer. In the problem analysis, authors used the linear and non-linear algorithms, feature extraction, feature transformation and feature selection. The results of investigation include the prognostic models with a predictive force based on the machine learning algorithms such as logistic regression, decision tree, randomize forest. Authors have validated models on available historical data. The developed models have the potential for practical use in the construction organizations while making new contracts.

  7. Automated discovery and construction of surface phase diagrams using machine learning

    International Nuclear Information System (INIS)

    Ulissi, Zachary W.; Singh, Aayush R.; Tsai, Charlie

    2016-01-01

    Surface phase diagrams are necessary for understanding surface chemistry in electrochemical catalysis, where a range of adsorbates and coverages exist at varying applied potentials. These diagrams are typically constructed using intuition, which risks missing complex coverages and configurations at potentials of interest. More accurate cluster expansion methods are often difficult to implement quickly for new surfaces. We adopt a machine learning approach to rectify both issues. Using a Gaussian process regression model, the free energy of all possible adsorbate coverages for surfaces is predicted for a finite number of adsorption sites. Our result demonstrates a rational, simple, and systematic approach for generating accurate free-energy diagrams with reduced computational resources. Finally, the Pourbaix diagram for the IrO_2(110) surface (with nine coverages from fully hydrogenated to fully oxygenated surfaces) is reconstructed using just 20 electronic structure relaxations, compared to approximately 90 using typical search methods. Similar efficiency is demonstrated for the MoS_2 surface.

  9. Tracking Porters: Learning the Craft of Techno-Anthropology.

    2015-01-01

    Anthropology attempts to gain insight into people's experiential life-worlds through long-term fieldwork. The quality of anthropological knowledge production, however, does not depend solely on the duration of the stay in the field, but also on a particular way of seeing social situations. The anthropological perspective is grounded in socio-cultural theory and forged by a distinct relativist or contextualist epistemological stance. The point is to understand events, concepts and phenomena from the insiders' point of view and to show how this view relates to the particular social and cultural context. In this chapter, we argue that although anthropology has its specific methodology - including a myriad of ethnographic data-gathering tools, techniques, analytical approaches and theories - it must first and foremost be understood as a craft. Anthropology as craft requires a specific 'anthropological sensibility' that differs from the standardized procedures of normal science. To establish our points we use an example of problem-based project work conducted by a group of Techno-Anthropology students at Aalborg University, we focus on key aspects of this craft and how the students began to learn it: For two weeks the students followed the work of a group of porters. Drawing on anthropological concepts and research strategies the students gained crucial insights about the potential effects of using tracking technologies in the hospital.

    2018-05-01

    Machine learning has led to important advances in society. One of the most exciting applications of machine learning in psychological science has been the development of assessment tools that can powerfully predict human behavior and personality traits. Thus far, machine learning approaches to personality assessment have focused on the associations between social media and other digital records with established personality measures. The goal of this article is to expand the potential of machine learning approaches to personality assessment by embedding it in a more comprehensive construct validation framework. We review recent applications of machine learning to personality assessment, place machine learning research in the broader context of fundamental principles of construct validation, and provide recommendations for how to use machine learning to advance our understanding of personality.

    2015-10-01

    The present study addressed employee job crafting behaviors (i.e., seeking resources, seeking challenges, and reducing demands) in the context of organizational change. We examined predictors of job crafting both at the organizational level (i.e., perceived impact of the implemented changes on the working life of employees) and the individual level (i.e., employee willingness to follow the changes). Job crafting behaviors were expected to predict task performance and exhaustion. Two-wave longitudinal data from 580 police officers undergoing organizational changes were analyzed with structural equation modeling. Findings showed that the degree to which changes influence employees' daily work was linked to reducing demands and exhaustion, whereas employee willingness to change was linked to seeking resources and seeking challenges. Furthermore, while seeking resources and seeking challenges were associated with high task performance and low exhaustion respectively, reducing demands seemed to predict exhaustion positively. Our findings suggest that job crafting can act as a strategy of employees to respond to organizational change. While seeking resources and seeking challenges enhance employee adjustment and should be encouraged by managers, reducing demands seems to have unfavorable implications for employees.

  3. Emotions in Risk Assessment and Decision Making Processes During Craft Practice

    Directory of Open Access Journals (Sweden)

    Camilla Groth

    2015-12-01

    Full Text Available Traditionally subjective experiences and emotions have been overlooked in the practice of scientific research. In the field of design and craft research too, feelings and emotions have been considered as interfering with the rigour of research. However, as a result of findings in neuroscience, a new understanding has emerged, providing emotions a central role in risk assessment and decision making processes. This has implications also for how we understand craft practice. In this practice-led research, a craft practitioner analysed five video-recordings of herself while throwing clay blindfolded. The researcher-practitioner specifically studied critical incidents in the throwing process and made a detailed analysis of how sensory experiences and emotions guided her in risk assessment, decision making, and problem solving during the clay-throwing sessions. She found that her tactile experience gave her important clues on the condition of the material and its consequent possibilities at different stages. These experiences in turn affected her emotions in either positive or negative ways, affecting her risk assessment, decision making, and problem solving activities. This research has shown that sensory experiences and emotions influence the craft making process and are thus important elements in the expertise of the craftsperson. The role of such emotions remains to be studied further in the expertise of researchers in general.

The graft reaction conditions, such as the amount of catalyst added, the reaction temperature, and the reaction time were optimized for the Friedel-Crafts alkylation of the MWCNTs with poly(vinyl chloride (PVC with anhydrous aluminum chloride (AlCl3 as catalyst in chloroform (CHCl3. The Fourier Transform Infrared (FT-IR, Raman, and thermogravimetric (TGA analysis showed that PVC had been successfully grafted onto MWCNTs both at the ends and on the sidewalls by the proposed Friedel-Crafts alkylation. The PVC grafted MWCNTs (PVC-MWCNTs could be dispersed well in organic solvent and the dispersion was more stable.

    Full Text Available Currently beer is booming, mainly due to the steady rise of craft breweries worldwide. Previous surveys for occurrence of mycotoxins in beer, were mainly focussed on industrial produced beer. The present survey reports the presence of mycotoxins in craft beer and how this compares to industrial produced beer. More than 1000 beers were collected from 47 countries, of which 60% were craft beers. A selection of 1000 samples were screened for the presence of aflatoxin B1, ochratoxin A (OTA, zearalenone (ZEN, fumonisins (FBs, T-2 and HT-2 toxins (T-2 and HT-2 and deoxynivalenol (DON using a mycotoxin 6-plex immunoassay. For confirmatory analysis, a liquid chromatography tandem mass spectrometry (LC-MS/MS method was developed and applied. The 6-plex screening showed discrepancies with the LC-MS/MS analysis, possibly due to matrix interference and/or the presence of unknown mycotoxin metabolites. The major mycotoxins detected were DON and its plant metabolite deoxynivalenol-3-β-D-glucopyranoside (D3G. The 6-plex immunoassay reported the sum of DON and D3G (DON+D3G contaminations ranging from 10 to 475 μg/L in 406 beers, of which 73% were craft beers. The popular craft beer style imperial stout, had the highest percentage of samples suspected positive (83% with 29% of all imperial stout beers having DON+D3G contaminations above 100 μg/L. LC-MS/MS analysis showed that industrial pale lagers from Italy and Spain, predominantly contained FBs (3-69 μg/L. Besides FBs, African traditional beers also contained aflatoxins (0.1-1.2 μg/L. The presence of OTA, T-2, HT-2, ZEN, β-zearalenol, 3/15-acetyl-DON, nivalenol and the conjugated mycotoxin zearalenone 14-sulfate were confirmed in some beers.

    The oil spill which occurred recently in the Gulf of Mexico highlighted the lack of efficient oil spill clean-up equipment for an offshore environment. With the increase in industrial operations in the Arctic Seas it is of high importance to develop an efficient oil spill response as the absence of reliable oil spill contingency plans will not be tolerated in such environmentally sensitive areas. The aim of this paper is to present the use of the ARKTOS amphibious craft for cleaning up an oil spill in the Arctic. This craft is usually used for logistical services and evacuation purposes; its use for clean-up purposes has been under study since 2000. This study showed that the ARKTOS craft could be an efficient means for oil spill clean-up in the Arctic because of its proven ice capable amphibious platforms and its hydraulic power; however oil collection trials should be performed to validate it.

    Starting out as a professional tattooist back in 1977 in Copenhagen, Denmark, Frank Rosenkilde has personally experienced the remarkable development of tattoo machines, needles and utilities: all the way from home-made equipment to industrial products of substantially improved quality. Machines can be constructed like the traditional dual-coil and single-coil machines or can be e-coil, rotary and hybrid machines, with the more convenient and precise rotary machines being the recent trend. This development has resulted in disposable needles and utilities. Newer machines are more easily kept clean and protected with foil to prevent crosscontaminations and infections. The machines and the tattooists' knowledge and awareness about prevention of infection have developed hand-in-hand. For decades, Frank Rosenkilde has been collecting tattoo machines. Part of his collection is presented here, supplemented by his personal notes. © 2015 S. Karger AG, Basel.

  20. Sarawak Bamboo Craft: Symbolism and Phenomenon

    Directory of Open Access Journals (Sweden)

    Arshad Mohd Zaihidee

    2014-04-01

    Full Text Available The relationship between human beings and their environment has stirred reactions between nature and the development of mind and actions that can be discussed using interdisciplinary approaches such as psychology, sociology, anthropology and history, in understanding human thinking and behavior. A psychological approach is intended to evaluate the individual choices and needs in society. A sociological approach details the various patterns in the social organization. An anthropological approach is tied with culture and belief to fulfil human needs which are based on their habitat, while a historical approach looks at the development which is related to the past. Dimensions of experiences, order and logic, selective elaboration and expressions are used to analyze the bamboo craft of Iban, Melanau and Bidayuh societies in Sarawak long-houses. The existence of constitutive, moral, expressive and cognitive symbols has been interpreted based on a theoretical framework that has been developed by Langer Art Theory, Parsons Social Theory and Kaplan Culture Theory. The values and meaning formed are interpreted to understand matters related to the lives of villagers and the finding suggests that bamboo craft expresses the multi-ethnic mind and character in the socio-culture of long- houses in Sarawak.

  1. Purpose and pleasure in late life: Conceptualising older women's participation in art and craft activities.

    2013-12-01

    The fourth age, as the last stage of life, represents a final challenge to find personal meaning in the face of changing capacities, illness and disability. Participation in valued activities is important for sustaining interest in life and has been associated with enhanced health and well-being. Art and craft activities are a popular form of participation amongst women in late life with growing international interest in the potential for these types of activities to maintain health and well-being and address problems of social isolation. Drawing on open text comments from 114 women enrolled in the Australian Longitudinal Study on Women's Health and in-depth interviews with 23 women all aged in their eighties, this paper explores the nature of older women's participation in art and craft activities and conceptualises links between participation in these activities and health and well-being in late life. Participation in art and craft activities is complex and dynamic, comprising cognitive and physical processes infused with emotion and occurs in the context of social relationships, physical spaces, physical ailments and beliefs about the value of the activities. By participating in art and craft activities, older women find purpose in their lives, contributing to their subjective well-being whilst helping and being appreciated by others. They develop a self view as enabled and as such take on new art and craft challenges, continue to learn and develop as art and craft makers and remain open to new possibilities. © 2013.

  2. Job crafting and its impact on work engagement and job satisfaction in mining and manufacturing

    2016-09-01

    Full Text Available The purpose of this study was to investigate job crafting and its relationship with work engagement and job satisfaction within the South African context. This research is important as job crafting has been shown to have a positive influence on employee motivation. A cross-sectional survey design was used to collect primary data from organisations in the mining and manufacturing industries of South Africa (N = 470. The results of multi-group structural equation modelling showed that the original four-factor structure of the job crafting scale was supported by the data, but that a three-factor structure was necessary due to a discriminant validity concern regarding two job crafting dimensions. Regression results revealed that increasing structural job resources with challenging job demands, and increasing social job resources were significant predictors of work engagement in both groups. Contrary to expectations decreasing hindering job demands was a negative predictor of job satisfaction in the mining group. Furthermore, increasing social job resources was also a significant predictor of job satisfaction in both groups. This study indicates the importance of job crafting for work engagement and job satisfaction in organisations.

  8. Machine Learning in Computer-Aided Synthesis Planning.

    Science.gov (United States)

    Coley, Connor W; Green, William H; Jensen, Klavs F

    2018-05-15

    Computer-aided synthesis planning (CASP) is focused on the goal of accelerating the process by which chemists decide how to synthesize small molecule compounds. The ideal CASP program would take a molecular structure as input and output a sorted list of detailed reaction schemes that each connect that target to purchasable starting materials via a series of chemically feasible reaction steps. Early work in this field relied on expert-crafted reaction rules and heuristics to describe possible retrosynthetic disconnections and selectivity rules but suffered from incompleteness, infeasible suggestions, and human bias. With the relatively recent availability of large reaction corpora (such as the United States Patent and Trademark Office (USPTO), Reaxys, and SciFinder databases), consisting of millions of tabulated reaction examples, it is now possible to construct and validate purely data-driven approaches to synthesis planning. As a result, synthesis planning has been opened to machine learning techniques, and the field is advancing rapidly. In this Account, we focus on two critical aspects of CASP and recent machine learning approaches to both challenges. First, we discuss the problem of retrosynthetic planning, which requires a recommender system to propose synthetic disconnections starting from a target molecule. We describe how the search strategy, necessary to overcome the exponential growth of the search space with increasing number of reaction steps, can be assisted through a learned synthetic complexity metric. We also describe how the recursive expansion can be performed by a straightforward nearest neighbor model that makes clever use of reaction data to generate high quality retrosynthetic disconnections. Second, we discuss the problem of anticipating the products of chemical reactions, which can be used to validate proposed reactions in a computer-generated synthesis plan (i.e., reduce false positives) to increase the likelihood of experimental success

    2015-06-01

    Assessment of multi-intelligence fusion techniques includes credibility of algorithm performance, quality of results against mission needs, and usability in a work-domain context. Situation awareness (SAW) brings together low-level information fusion (tracking and identification), high-level information fusion (threat and scenario-based assessment), and information fusion level 5 user refinement (physical, cognitive, and information tasks). To measure SAW, we discuss the SAGAT (Situational Awareness Global Assessment Technique) technique for a multi-intelligence fusion (MIF) system assessment that focuses on the advantages of MIF against single intelligence sources. Building on the NASA TLX (Task Load Index), SAGAT probes, SART (Situational Awareness Rating Technique) questionnaires, and CDM (Critical Decision Method) decision points; we highlight these tools for use in a Multi-Intelligence Critical Rating Assessment of Fusion Techniques (MiCRAFT). The focus is to measure user refinement of a situation over the information fusion quality of service (QoS) metrics: timeliness, accuracy, confidence, workload (cost), and attention (throughput). A key component of any user analysis includes correlation, association, and summarization of data; so we also seek measures of product quality and QuEST of information. Building a notion of product quality from multi-intelligence tools is typically subjective which needs to be aligned with objective machine metrics.

  10. Using Phun to Study ``Perpetual Motion'' Machines

    Science.gov (United States)

    Koreš, Jaroslav

    2012-05-01

    The concept of "perpetual motion" has a long history. The Indian astronomer and mathematician Bhaskara II (12th century) was the first person to describe a perpetual motion (PM) machine. An example of a 13th- century PM machine is shown in Fig. 1. Although the law of conservation of energy clearly implies the impossibility of PM construction, over the centuries numerous proposals for PM have been made, involving ever more elements of modern science in their construction. It is possible to test a variety of PM machines in the classroom using a program called Phun2 or its commercial version Algodoo.3 The programs are designed to simulate physical processes and we can easily simulate mechanical machines using them. They provide an intuitive graphical environment controlled with a mouse; a programming language is not needed. This paper describes simulations of four different (supposed) PM machines.4

    International Nuclear Information System (INIS)

    Phillips, M. K.

    2008-01-01

    As utilities and project developers in the United States embark on a new nuclear plant construction endeavor, the industry must have the confidence and support of all stakeholders. To gain this confidence and support, cost and schedule certainty must be established. Therein lies the challenge. The owner will insist that constructors and suppliers deliver new plants on time and within project budgets. This will be a significant effort given the limited number of qualified equipment and commodity suppliers, and a shortage of experienced craft and supervision. In an effort to manage construction risk and ensure cost and schedule certainty, the AREVA Construction Management Team has lead the development of a construction strategy that includes advanced construction methods and technologies such as 3-D modeling, detailed planning and scheduling, open-top construction, state-of-the-art fabrication practices, specialty transportation and lifting methods, and pre-assembly and modularization, otherwise referred to as construction optimization. Unlike off-shore platforms, industrial process plants, and ships where piping and components can be integrated into the steel building structure, optimized construction of nuclear plants must consider reinforced concrete walls and slabs that serve as the building structure, and provide radiation shielding and containment of nuclear systems. These differences in design and construction require a significantly different analysis approach that is focused on rooms of a building rather than the whole building or plant. This paper will focus on the process developed and currently being implemented by the U.S. EPR (Evolutionary Power Reactor) Construction Team to identify opportunities for optimization and then to evaluate and select the rooms or areas of the plant where pre-assembly or modularization will provide the greatest benefit to construction cost and schedule certainty. Key measures for comparison and selection are critical path

  13. Classification of radiolarian images with hand-crafted and deep features

    2017-12-01

    Radiolarians are planktonic protozoa and are important biostratigraphic and paleoenvironmental indicators for paleogeographic reconstructions. Radiolarian paleontology still remains as a low cost and the one of the most convenient way to obtain dating of deep ocean sediments. Traditional methods for identifying radiolarians are time-consuming and cannot scale to the granularity or scope necessary for large-scale studies. Automated image classification will allow making these analyses promptly. In this study, a method for automatic radiolarian image classification is proposed on Scanning Electron Microscope (SEM) images of radiolarians to ease species identification of fossilized radiolarians. The proposed method uses both hand-crafted features like invariant moments, wavelet moments, Gabor features, basic morphological features and deep features obtained from a pre-trained Convolutional Neural Network (CNN). Feature selection is applied over deep features to reduce high dimensionality. Classification outcomes are analyzed to compare hand-crafted features, deep features, and their combinations. Results show that the deep features obtained from a pre-trained CNN are more discriminative comparing to hand-crafted ones. Additionally, feature selection utilizes to the computational cost of classification algorithms and have no negative effect on classification accuracy.

    Full Text Available This article reports on experiments from our ongoing project whose goal is to develop a C++ library which supports adaptive and irregular data structures on distributed memory supercomputers. We demonstrate the use of our abstractions in implementing "tree codes" for large-scale N-body simulations. These algorithms require dynamically evolving treelike data structures, as well as load-balancing, both of which are widely believed to make the application difficult and cumbersome to program for distributed-memory machines. The ease of writing the application code on top of our C++ library abstractions (which themselves are application independent, and the low overhead of the resulting C++ code (over hand-crafted C code supports our belief that object-oriented approaches are eminently suited to programming distributed-memory machines in a manner that (to the applications programmer is architecture-independent. Our contribution in parallel programming methodology is to identify and encapsulate general classes of communication and load-balancing strategies useful across applications and MIMD architectures. This article reports experimental results from simulations of half a million particles using multiple methods.

For millennia, arts and crafts of Dagestan have been organically linked with the life of people and their everyday way of life and daily activities, with their worldview and understanding of beauty. In the middle of the 1st millennium BC in the mountainous Dagestan, art of bronze casting has reached a high degree of perfection, most vividly represented by statues of different wild and domestic animals. Images of animals are interpreted generically, without study of small details, but with the characteristic features of the exterior. Paired images of birds are often found in the arts and crafts of the medieval Dagestan. This heraldic composition, two-part or in conjunction with the sacred tree - a three-part, presented in metal-plastic and carved stone and wood, was one of the most popular and enduring decorative items that was common during the Middle Ages and has survived to the present day. This also has been further developed and improved and inherited by craftsmen of Dagestan.Conclusion. When creating works of arts and crafts craftsmen use diverse traditional arts and engineering techniques, the ancient but substantially revised and reinterpreted iconic scenes and ornamental motifs. In art, folk craftsmen emphasize the unity of man and nature. Most ornamental motifs common in Dagestan, go back to the very specific nature prototypes. Compositional structure, as the artistic analysis shows, is often borrowed from nature. This feeling becomes a condition for cultural and biological development, acting as a factor of co-evolution of man and nature.

    Full Text Available The objective of this research is to analyze the construction of the wind machine for draining marshy ground designed by Agustin de Betancourt and Molina in 1789. To do this, a static analysis by finite elements method from the threedimensional model obtained with Autodesk Inventor Professional has been performed. The results show that the greatest stresses of the mechanism take place when the main shaft is meshed with the cogwheel, namely the point of contact between the worm screw and cogwheel. However, the maximum displacements and the greatest deformations take place in the blades. In addition, the mechanism is oversized, reaching at no point the tensile strength of the material, confirming the successful construction of this historical invention.

    Full Text Available AbstractJob crafting behavior refers to the changes made by workers in their job context for adjusting their activities to their preferences. We sought to adapt and collect validity evidences of the Job Crafting Behaviors Scale for the Brazilian context, in a sample of 491 workers, with a mean age of 26.7 years. Factor analysis revealed that the final instrument consisted of three dimensions (increasing structural job resources, increasing social job resources, increasing challenging job demands, which showed good internal consistency indexes. These dimensions showed low or moderate correlations with work engagement, positive psychological capital, positive job affect, and in-role performance. The scale showed evidence of validity, the use of which is recommended for future research on the changes that people make in their jobs.

  10. Job Crafting: Older Workers’ Mechanism for Maintaining Person-Job Fit

    Wong, Carol M.; Tetrick, Lois E.

    2017-01-01

    Aging at work is a dynamic process. As individuals age, their motives, abilities and values change as suggested by life-span development theories (Lang and Carstensen, 2002; Kanfer and Ackerman, 2004). Their growth and extrinsic motives weaken while intrinsic motives increase (Kooij et al., 2011), which may result in workers investing their resources in different areas accordingly. However, there is significant individual variability in aging trajectories (Hedge et al., 2006). In addition, the changing nature of work, the evolving job demands, as well as the available opportunities at work may no longer be suitable for older workers, increasing the likelihood of person-job misfit. The potential misfit may, in turn, impact how older workers perceive themselves on the job, which leads to conflicting work identities. With the traditional job redesign approach being a top-down process, it is often difficult for organizations to take individual needs and skills into consideration and tailor jobs for every employee (Berg et al., 2010). Therefore, job crafting, being an individualized process initiated by employees themselves, can be a particularly valuable mechanism for older workers to realign and enhance their demands-abilities and needs-supplies fit. Through job crafting, employees can exert personal agency and make changes to the task, social and cognitive aspects of their jobs with the goal of improving their work experience (Wrzesniewski and Dutton, 2001). Building on the Life Span Theory of Control (Heckhausen and Schulz, 1995), we posit that job crafting, particularly cognitive crafting, will be of increasing value as employees age. Through reframing how they think of their job and choosing to emphasize job features that are personally meaningful, older workers can optimize their resources to proactively redesign their jobs and maintain congruent, positive work identities.

    Full Text Available The development of efficient Friedel–Crafts alkylations of arenes and heteroarenes using only catalytic amounts of a Lewis acid has gained much attention over the last decade. The new catalytic approaches described in this review are favoured over classical Friedel–Crafts conditions as benzyl-, propargyl- and allyl alcohols, or styrenes, can be used instead of toxic benzyl halides. Additionally, only low catalyst loadings are needed to provide a wide range of products. Following a short introduction about the origin and classical definition of the Friedel–Crafts reaction, the review will describe the different environmentally benign substrates which can be applied today as an approach towards greener processes. Additionally, the first diastereoselective and enantioselective Friedel–Crafts-type alkylations will be highlighted.

  15. Forecasting manpower requirements for nuclear power plant construction

    Seltzer, N.; Schriver, W.R.

    1978-01-01

    This paper presents both the methodology and results of a segment of a comprehensive construction manpower demand forecasting system aimed at forecasting virtually all construction manpower requirements in the United States of America. The part of the system dealing with the demand for construction workers needed to build nuclear powered electricity generating plants is discussed here. The object of the system is to forecast manpower construction needs for each of 29 construction crafts on a monthly basis in each of 10 geographical regions of the United States. The method used is to establish profiles of the types of workers and time phasing required in the past. Profiling was done for different types of plants, different capacity classes, and different geographical locations. An appropriate worker profile matrix cannot simply be multiplied by the capacity of the proposed plant if the number of man-hours required per kilowatt of generating capacity is not constant. The value of this latter variable has changed considerably recently - presumably because of an increased awareness of environmental and safety considerations. Econometric techniques are used to forecast values for man-hours per kilowatt which are then multiplied by projected new capacity to be put in place. The resulting total man-hour requirement is then allocated over time and by craft through use of a worker profile matrix. The summary results indicate that 20 percent increases in man-hours required per kilowatt of capacity can be expected between 1977 and 1981. Total construction labour demand will rise from 65,700 work-years in 1977 to nearly 96,600 work-years in 1981. Forecasts of the actual number of different types of workers to be demanded in each month and in each region are available from the system. (author)

    The use of a large diameter high production tunnel boring machine interfaced with a high capacity continuous belt conveyor system provides a highly productive and cost effective construction system for both civil and mining tunnels. Continuous advance of the tunnel boring machine for a distance of 1,000 feet (305 m) allows for very efficient operation of the system. The available cost reductions will likely prove that this approach to waste handling will make marginally viable projects economically feasible. 9 refs., 10 figs., 1 tab.

    Job crafting, an employee-initiated job design/redesign, has become important for employees' well-being such as work engagement. This study examined the effectiveness of a newly developed job crafting intervention program on work engagement (as primary outcome), as well as job crafting and psychological distress (as secondary outcomes), using a pretest-posttest study design among Japanese employees. Participants were managers of a private company and a private psychiatric hospital in Japan. The job crafting intervention program consisted of two 120-min sessions with a two-week interval between them. Outcomes were assessed at baseline (Time 1), post-intervention (Time 2), and a one-month follow-up (Time 3). The mixed growth model analyses were conducted using time (Time 1, Time 2, and Time 3) as an indicator of intervention effect. Effect sizes were calculated using Cohen's d. The program showed a significant positive effect on work engagement (t = 2.20, p = 0.03) in the mixed growth model analyses, but with only small effect sizes (Cohen's d = 0.33 at Time 2 and 0.26 at Time 3). The program also significantly improved job crafting (t = 2.36, p = 0.02: Cohen's d = 0.36 at Time 2 and 0.47 at Time 3) and reduced psychological distress (t = -2.06, p = 0.04: Cohen's d = -0.15 at Time 2 and -0.31 at Time 3). The study indicated that the newly developed job crafting intervention program was effective in increasing work engagement, as well as in improving job crafting and decreasing psychological distress, among Japanese managers.

    Inertial sensors are one of the most commonly used sources of data for human activity recognition (HAR) and exercise detection (ED) tasks. The time series produced by these sensors are generally analyzed through numerical methods. Machine learning techniques such as random forests or support vector machines are popular in this field for classification efforts, but they need to be supported through the isolation of a potentially large number of additionally crafted features derived from the raw data. This feature preprocessing step can involve nontrivial digital signal processing (DSP) techniques. However, in many cases, the researchers interested in this type of activity recognition problems do not possess the necessary technical background for this feature-set development. The study aimed to present a novel application of established machine vision methods to provide interested researchers with an easier entry path into the HAR and ED fields. This can be achieved by removing the need for deep DSP skills through the use of transfer learning. This can be done by using a pretrained convolutional neural network (CNN) developed for machine vision purposes for exercise classification effort. The new method should simply require researchers to generate plots of the signals that they would like to build classifiers with, store them as images, and then place them in folders according to their training label before retraining the network. We applied a CNN, an established machine vision technique, to the task of ED. Tensorflow, a high-level framework for machine learning, was used to facilitate infrastructure needs. Simple time series plots generated directly from accelerometer and gyroscope signals are used to retrain an openly available neural network (Inception), originally developed for machine vision tasks. Data from 82 healthy volunteers, performing 5 different exercises while wearing a lumbar-worn inertial measurement unit (IMU), was collected. The ability of the

    Full Text Available In a holistic craft process, the same person designs a visual and technical appearance, produces the design with craft materials and technologies, make necessary changes to the design during its production and finally assesses the process and the finished product. Similarly, in the educational context, students should make craft products starting with the design process. These kinds of designing and hands-on activities nurture students’ creativity and problem-solving skills and offer them an opportunity to test their ideas and see them realised. Testing and further developing pedagogical approaches to holistic craft is important from the perspective of the renewal of the national core curriculum (2016 in Finland, which emphasises holistic approaches and the integration of different content areas. This study presents an experiential learning model of combining literature education, ethic-moral education and craft. Kolb’s model of experiential learning gives a solid and systematic theoretical base for this LCE model (one combining literature, craft and ethic-moral education. The teaching experiment is implemented as a craft process supported with children’s literature and activities based on a story. It seems that children can derive benefit from literature and activities during a craft making process. In addition, referencing literature enables the teacher to combine the craft process with multiple learning targets, fostering both ethical and content skills. We present the LCE model both in the light of an experiential learning model and the pragmatic implementations it gives rise to. According to our experiments, experiential learning can be meaningfully applied to the holistic craft process and craft education. Furthermore, the LCE model helps students to commit to holistic craft by nurturing a personal attachment.

    Full Text Available The main aim of this article is to describe an ongoing study to recover the memories of the people and the traditional crafts associated with the Guadalquivir River where it passes through a town called C., 12km from the city of S. in the south of Spain. It seems that people are losing their sense of belonging to both a symbolic and geographical territory. The process for recovering it can be considered a generator of experiences and learning. These experiences are related to identity as an element which enables people to understand how individuals establish relationships amongst themselves and with the environment. The paper describes the process of research based on interviewing people to capture their experiences. This is a work in process. The first outcomes are related to a number of descriptive categories such as: the crafts associated with the River; the use of the River to transport goods and people; the family ties associated with the crafts; the cosmopolitanism of the people and the changes ensuing from it; the role of women; and the River as a magical and mysterious place. Preliminary conclusions call on us to consider the importance of recovering traditional crafts as a source of adult education, and of maintaining a cultural identity threatened by globalisation processes.

    Full Text Available In cities across the Soviet Union in the late 1950s and early 1960s, new housing developments of plain five-storey apartment blocks mushroomed thanks to an intensive programme for mass industrialised housing construction launched by the Party-State in 1957. Modern living conditions were to be created for millions, it was promised, through state planning and investment in the modernisation of construction, making maximum use of technology and factory prefabrication in place of bricklaying and other artisanal methods. Drawing on oral history and material culture, this article attends to some contradictory, seemingly unplanned and un-modern aspectsof popular agency entailed in producing the modern Soviet environment, including the role of local improvisation, DIY and manual craft. These were not necessarily resistant to or subversive of the socialist state's modernisationproject but had a more complex and ambivalent relation to it, as complementary or compensatory accommodations that"tuned" universal modelsto local contingency.

  12. BioCraft: Using Gamification to Stimulate Students' Motivation and Acquisition of Scientific Terms in a Bilingual Classroom

    Turner, Kent Alan

    Gamification is the act of introducing game elements in any aspect of life. In this case, it is a classroom. The operating model of BioCraft was a role-playing game that reinforced deaf students' use of new vocabulary in a gamified environment. BioCraft addressed the problem of deaf students acquiring scientific terms and using these scientific terms bilingually in academic language. BioCraft also established a student-centered learning atmosphere that promoted intersubjectivity, appropriation, and self-determination. In BioCraft, students became avatars of new organisms living on a new planet who needed to learn about living systems, adaptations, and genetics in order to survive. The results of the operating model suggested that gamification had an effect on deaf students' motivation and frequency of using new scientific terms with minimal persuasion from the teacher.

    Full Text Available External factors such as blurring market boundaries, escalating customer diversity and increasing global competitive threats have forced businesses to build strategies around key products and formulate market-driven strategies that are integrated with relationship and supply chain strategies to deliver superior customer value. Indeed, in the modern era of supply chain management, organisations are getting more integrated with their suppliers and customers as a way to manage the total supply chain. The purpose of this research was to determine if product strategies and supply chain practices of small craft business are aligned. Personal in-depth interviews were conducted with nine craft businesses operating in Gauteng Province, South Africa. The findings revealed that craft businesses struggle to match their product strategies with their supply chain strategies. Craft businesses also exhibited some inbound supply chain weaknesses.

    The tunnel boring machine (TBM) can construct an underground tunnel efficiently and without construction noise vibration related problems. Many civil projects, such as NPP construction, set importance on the economics of construction. Thus, advance rate, which is the speed at which the TBM is able to progress along its intended route, is one of the key factors affecting construction period and construction expenses. As the saying goes, time is money. Right Double Quotation Mark In addition, it is important to manage construction permits and civil complaints, even when construction expenses and construction periods are excluded. So, accurate prediction for advance rate is important when designing tunnel project. Several designers and project owners have tried to improve construction efficiency and tunneling advance rate.. There have been several studies on managing the rate of wear, designing an optimum tunnel face, and finding the optimum cutter spacing. Cutter replacements due to cutter wear and tear are very important because the wear and tear of cutters attached to the cutter head profoundly affect the advance rate. To manage cutter wear and tear is to control parameters related to cutter shape and cutter wear rate. There have been studies on the relationship between rock properties or TBM characteristics, and cutter wear or replacement. However, many of these studies relied on computer simulations or other small scale experiments. Therefore, this paper attempts to present a correlation between cutter replacement or cutter wear, against various parameters using practical data such as rock quality and TBM shield specifications, from an actual construction site. This study was conducted to suggest directions in the improvement of TBM cutters by analyzing relationships between rock conditions and cutter maintenance as well as TBM advance rates.

  17. Application of CRAFT (complete reduction to amplitude frequency table) in nonuniformly sampled (NUS) 2D NMR data processing.

    Krishnamurthy, Krish; Hari, Natarajan

    2017-09-15

    The recently published CRAFT (complete reduction to amplitude frequency table) technique converts the raw FID data (i.e., time domain data) into a table of frequencies, amplitudes, decay rate constants, and phases. It offers an alternate approach to decimate time-domain data, with minimal preprocessing step. It has been shown that application of CRAFT technique to process the t 1 dimension of the 2D data significantly improved the detectable resolution by its ability to analyze without the use of ubiquitous apodization of extensively zero-filled data. It was noted earlier that CRAFT did not resolve sinusoids that were not already resolvable in time-domain (i.e., t 1 max dependent resolution). We present a combined NUS-IST-CRAFT approach wherein the NUS acquisition technique (sparse sampling technique) increases the intrinsic resolution in time-domain (by increasing t 1 max), IST fills the gap in the sparse sampling, and CRAFT processing extracts the information without loss due to any severe apodization. NUS and CRAFT are thus complementary techniques to improve intrinsic and usable resolution. We show that significant improvement can be achieved with this combination over conventional NUS-IST processing. With reasonable sensitivity, the models can be extended to significantly higher t 1 max to generate an indirect-DEPT spectrum that rivals the direct observe counterpart.

    1991-01-01

    Argonne National Laboratory is constructing a 7-GeV Advanced Photon Source for use as a synchrotron radiation source in basic and applied research. The controls and computing environment for this accelerator complex includes graphical operator interfaces to the machine based on Motif, X11, and PHIGS/PEX. Construction and operation of the control system for this accelerator relies upon interactive interface builder and diagram/editor type tools, as well as a run-time environment for the constructed displays which communicate with the physical machine via network connections. This paper discusses our experience with several commercial CUI builders, the inadequacies found in these, motivation for the development of an application- specific builder, and design and implementation strategies employed in the development of our own Man-Machine Interface builder. 5 refs

    2014-01-01

    Digital technologies are changing the relationship between design and construction: with computer models, CAD/CAM, and prototyping, designers can gain direct control of building and construction processes. The ability to digitally model designs, and thus to use those models directly in the context of production, creates a synthesis between design and construction in keeping with the tradition of the close relationship between design and craftsmanship, between the quality of the design and the rules of the craft. The evolution of the culture of design and construction is the underlying theme of this book. The aim is to discuss the direction that innovation is now taking, with a particular focus on today’s cutting-edge architectures. The method addresses the ways in which different societies have dealt with the issues of their age regarding design and construction, the different contributions provided by various techniques, and with them the meanings expressed by the architecture. As building design using dig...

    We present a systematic construction of environment-based abstract machines from context-sensitive calculi of explicit substitutions, and we illustrate it with ten calculi and machines for applicative order with an abort operation, normal order with generalized reduction and call/cc, the lambda......-mu-calculus, delimited continuations, stack inspection, proper tail-recursion, and lazy evaluation. Most of the machines already exist but have been obtained independently and are only indirectly related to the corresponding calculi. All of the calculi are new and they make it possible to directly reason about...... the execution of the corresponding machines. In connection with the functional correspondence between evaluation functions and abstract machines initiated by Reynolds, the present syntactic correspondence makes it possible to construct reduction-free normalization functions out of reduction-based ones, which...

    ITER sectors require more stringent tolerances ± 5 mm than normally expected for the size of structure involved. The walls of ITER sectors are made of 60 mm thick stainless steel and are joined together by high efficiency structural and leak tight welds. In addition to the initial vacuum vessel assembly, sectors may have to be replaced for repair. Since commercially available machines are too heavy for the required machining operations and the lifting of a possible e-beam gun column system, and conventional robots lack the stiffness and accuracy in such machining condition, a new flexible, lightweight and mobile robotic machine is being considered. For the assembly of the ITER vacuum vessel sector, precise positioning of welding end-effectors, at some distance in a confined space from the available supports, will be required, which is not possible using conventional machines or robots. This paper presents a special robot, able to carry out welding and machining processes from inside the ITER vacuum vessel, consisting of a ten-degree-of-freedom parallel robot mounted on a carriage driven by electric motor/gearbox on a track. The robot consists of a Stewart platform based parallel mechanism. Water hydraulic cylinders are used as actuators to reach six degrees of freedom for parallel construction. Two linear and two rotational motions are used for enlargement the workspace of the manipulator. The robot carries both welding gun such as a TIG, hybrid laser or e-beam welding gun to weld the inner and outer walls of the ITER vacuum vessel sectors and machining tools to cut and milling the walls with necessary accuracy, it can also carry other tools and material to a required position inside the vacuum vessel . For assembling an on line six degrees of freedom seam finding algorithm has been developed, which enables the robot to find welding seam automatically in a very complex environment. In the machining multi flexible machining processes carried out automatically by

    Specular-quality metal mirrors are being machined for use in laser optical systems. The fabrication process incorporates special quality diamond tools and specially constructed turning machines. The machines are controlled by advanced control techniques and are housed in an environmentally controlled laboratory to insure ultimate machine stability and positional accuracy. The materials from which these mirrors are primarily produced are the softer face-center-cubic structure metals, such as gold, silver, copper, and aluminum. Mirror manufacturing by the single-point diamond machining process is in an early stage of development, but it is anticipated that this method will become the most economical way for producing high-quality metal mirrors.

  8. Machine Learning Multi-Stage Classification and Regression in the Search for Vector-like Quarks and the Neyman Construction in Signal Searches

    CERN Document Server

    Leone, Robert Matthew

    A search for vector-like quarks (VLQs) decaying to a Z boson using multi-stage machine learning was compared to a search using a standard square cuts search strategy. VLQs are predicted by several new theories beyond the Standard Model. The searches used 20.3 inverse femtobarns of proton-proton collisions at a center-of-mass energy of 8 TeV collected with the ATLAS detector in 2012 at the CERN Large Hadron Collider. CLs upper limits on production cross sections of vector-like top and bottom quarks were computed for VLQs produced singly or in pairs, Tsingle, Bsingle, Tpair, and Bpair. The two stage machine learning classification search strategy did not provide any improvement over the standard square cuts strategy, but for Tpair, Bpair, and Tsingle, a third stage of machine learning regression was able to lower the upper limits of high signal masses by as much as 50%. Additionally, new test statistics were developed for use in the Neyman construction of confidence regions in order to address deficiencies in c...

    2018-03-01

    Previous studies have demonstrated the utility and applicability of machine learning techniques to jet physics. In this paper, we construct new observables for the discrimination of jets from different originating particles exclusively from information identified by the machine. The approach we propose is to first organize information in the jet by resolved phase space and determine the effective N -body phase space at which discrimination power saturates. This then allows for the construction of a discrimination observable from the N -body phase space coordinates. A general form of this observable can be expressed with numerous parameters that are chosen so that the observable maximizes the signal vs. background likelihood. Here, we illustrate this technique applied to discrimination of H\\to b\\overline{b} decays from massive g\\to b\\overline{b} splittings. We show that for a simple parametrization, we can construct an observable that has discrimination power comparable to, or better than, widely-used observables motivated from theory considerations. For the case of jets on which modified mass-drop tagger grooming is applied, the observable that the machine learns is essentially the angle of the dominant gluon emission off of the b\\overline{b} pair.

    Energy efficiency of construction machines is extremely low, because engines cannot follow sudden load changes. Solution is sought by developing a construction machine using as the motive force source a hybrid unit composed of an engine, a generator and batteries. The activities were advanced in the following five fields: (1) analysis on loads on existing construction machines, (2) development of hybrid move force unit, (3) development of an actuator device, (4) development of a control system, and (5) development of a hybrid construction machine simulating system. In Item (1), a control work on a 6-ton class hydraulic shovel was selected as a representative work, whereas the work was divided into seven modes to measure such output characteristics as fuel consumption and actuator output in each work, and the standard work load modes were established. In Item (2), motive force in the set load modes was measured to discover functional requirements on the motive force unit. In Item (5), the simulation model for the existing machines was used to evaluate the fuel consumption performance of the motive force unit. (NEDO)

    Full Text Available The interaction of electrons with a periodic potential of atoms in crystalline solids gives rise to band structure. The band structure of existing materials can be measured by photoemission spectroscopy and accurately understood in terms of the tight-binding model, however not many experimental approaches exist that allow to tailor artificial crystal lattices using a bottom-up approach. The ability to engineer and study atomically crafted designer materials by scanning tunnelling microscopy and spectroscopy (STM/STS helps to understand the emergence of material properties. Here, we use atom manipulation of individual vacancies in a chlorine monolayer on Cu(100 to construct one- and two-dimensional structures of various densities and sizes. Local STS measurements reveal the emergence of quasiparticle bands, evidenced by standing Bloch waves, with tuneable dispersion. The experimental data are understood in terms of a tight-binding model combined with an additional broadening term that allows an estimation of the coupling to the underlying substrate.

    Spent yeast from craft beers often includes more hops (Humulus lupulus L.) secondary metabolites than traditional recipes. These compounds include α- and β- acids, which are antimicrobial to the rumen hyper ammonia-producing bacteria (HAB) that are major contributors to amino acid degradation. The objective was to determine if the hops acids in spent craft brewer's yeast (CY; ~ 3·5 mg g(-1) hops acids) would protect it from degradation by caprine rumen bacteria and HAB when compared to a baker's yeast (BY; no hops acids). Cell suspensions were prepared by harvesting rumen fluid from fistulated goats, straining and differential centrifugation. The cells were re-suspended in media with BY or CY. After 24 h (39°C), HAB were enumerated and ammonia was measured. Fewer HAB and less ammonia was produced from CY than from BY. Pure culture experiments were conducted with Peptostreptococcus anaerobiusBG1 (caprine HAB). Ammonia production by BG1 from BY was greater than from CY. Ammonia production was greater when exogenous amino acids were included, but similar inhibition was observed in CY treatments. These results indicate that rumen micro-organisms deaminated the amino acids in CY to a lesser degree than BY. Spent brewer's yeast has long been included in ruminant diets as a protein supplement. However, modern craft beers often include more hops (Humulus lupulus L.) than traditional recipes. These compounds include α- and β- acids, which are antimicrobial to the rumen hyper ammonia-producing bacteria (HAB) that are major contributors to amino acid degradation. This study demonstrated that hops acids in spent craft brewer's yeast protected protein from destruction by HABin vitro. These results suggest that the spent yeast from craft breweries, a source of beneficial hops secondary metabolites, could have value as rumen-protected protein. Published 2016.

    Antenatal education within the National Health Service (NHS) is a service in decline within some hospital trusts. Classes on offer are being moved into online formats or discontinued completely. Whilst research into antenatal education remains limited, what is known is that good birth preparation is of value. "Participative preparation for childbirth can enhance women's overall satisfaction with the childbirth experience" (Schrader McMillan et al 2009: 49). There are pockets of excellent antenatal education within the NHS, but no system for regulating the quality and content. Traditional 'parent craft' classes can be oversubscribed, turning what should be a participative group into an audience. Offering good quality antenatal education has the potential to increase normality, improve the birth outcome and the experience of both woman and her birth partner. Is it time to ditch the parent craft and implement dynamic woman-focused education?

    2016-04-01

    Full Text Available Orientation: Personality provides a foundation for understanding employee job behaviours. It determines and reflects how they respond to their work situations. There is a shortage of previous researches that have specifically dealt with the predictive role of personality on job crafting. Job crafting is also a significantly new concept in the South African work context. It has both positive and negative consequences on employee job behaviours. Research purpose: The present study investigated the role of big five factors on predicting job crafting propensities amongst administrative employees in Alice, South Africa. Motivation for the study: The present study aimed to determine the role of big five factors on predicting job crafting propensities amongst administrative employees. It was premised on previous research that the big five factors are associated with many employee job behaviours. Research approach, design and method: The present study employed a quantitative, crosssectional research design with a sample of 246 administrative employees in Alice, South Africa. A biographical questionnaire, a Big Five Inventory, and a job crafting questionnaire were used to collect data. Main findings: The findings showed that big five factors of Conscientiousness, Extraversion, Agreeableness, Openness to experience and Neuroticism play a significant role in predicting job crafting propensities. Practical implications: The present study suggests that big five factors of Conscientiousness, Extraversion, Agreeableness, Openness to experience and Neuroticism have a predictive role on job crafting behaviours. Managers of tertiary institutions can therefore consider these big five personalities to understand and predict the impacts of their job design strategies on administrative employees’ behaviours. Contribution: The contribution of the study was significant in that it contributed to research literature representing the influence of the big five factors in

  12. Design of a Modular E-Core Flux Concentrating Axial Flux Machine: Preprint

    Energy Technology Data Exchange (ETDEWEB)

    Husain, Tausif; Sozer, Yilmaz; Husain, Iqbal; Muljadi, Eduard

    2015-08-24

    In this paper a novel E-Core axial flux machine is proposed. The machine has a double-stator, single-rotor configuration with flux-concentrating ferrite magnets and pole windings across each leg of an E-Core stator. E-Core stators with the proposed flux-concentrating rotor arrangement result in better magnet utilization and higher torque density. The machine also has a modular structure facilitating simpler construction. This paper presents a single-phase and a three-phase version of the E-Core machine. Case studies for a 1.1-kW, 400-rpm machine for both the single-phase and three-phase axial flux machines are presented. The results are verified through 3D finite element analysis. facilitating simpler construction. This paper presents a single-phase and a three-phase version of the E-Core machine.

    Science.gov (United States)

    Nurul Misbah, Mohammad; Setyawan, Dony; Murti Dananjaya, Wisnu

    2018-03-01

    This research aims to determine the longitudinal strength of passenger ship which was converted from Landing Craft Tank with 54 m of length as stated by BKI (Biro Klasifikasi Indonesia / Indonesian Classification Bureau). Verification of strength value is done to 4 (four) loading conditions which are (1) empty load condition during sagging wave, (2) empty load condition during hogging wave, (3) full load condition during sagging wave and (4) full load condition during hogging wave. Analysis is done using Finite Element Analysis (FEA) software by modeling the entire part of passenger ship and its loading condition. The back and upfront part of ship centerline were used as the boundary condition. From that analysis it can be concluded that the maximum stress for load condition (1) is 72,393 MPa, 74,792 MPa for load condition (2), 129,92 MPa for load condition (3), and 132,4 MPa for load condition (4). Longitudinal strength of passenger ship fulfilled the criteria of empty load condition having smaller stress value than allowable stress which is 90 MPa, and during full load condition with smaller stress value than allowable stress which is 150 MPa. Analysis on longitudinal strength comparison with entire ship plate thickness variation of ± 2 mm from initial plate was also done during this research. From this research it can be concluded that plate thickness reduction causes the value of longitudinal strength to decrease, while plate thickness addition causes the value of longitudinal strength to increase.

  16. Smile (System/Machine-Independent Local Environment)

    Energy Technology Data Exchange (ETDEWEB)

    Fletcher, J.G.

    1988-04-01

    This document defines the characteristics of Smile, a System/machine-independent local environment. This environment consists primarily of a number of primitives (types, macros, procedure calls, and variables) that a program may use; these primitives provide facilities, such as memory allocation, timing, tasking and synchronization beyond those typically provided by a programming language. The intent is that a program will be portable from system to system and from machine to machine if it relies only on the portable aspects of its programming language and on the Smile primitives. For this to be so, Smile itself must be implemented on each system and machine, most likely using non-portable constructions; that is, while the environment provided by Smile is intended to be portable, the implementation of Smile is not necessarily so. In order to make the implementation of Smile as easy as possible and thereby expedite the porting of programs to a new system or a new machine, Smile has been defined to provide a minimal portable environment; that is, simple primitives are defined, out of which more complex facilities may be constructed using portable procedures. The implementation of Smile can be as any of the following: the underlying software environment for the operating system of an otherwise {open_quotes}bare{close_quotes} machine, a {open_quotes}guest{close_quotes} system environment built upon a preexisting operating system, an environment within a {open_quotes}user{close_quotes} process run by an operating system, or a single environment for an entire machine, encompassing both system and {open_quotes}user{close_quotes} processes. In the first three of these cases the tasks provided by Smile are {open_quotes}lightweight processes{close_quotes} multiplexed within preexisting processes or the system, while in the last case they also include the system processes themselves.

  17. Sustainability Evaluation of Power Grid Construction Projects Using Improved TOPSIS and Least Square Support Vector Machine with Modified Fly Optimization Algorithm

    Directory of Open Access Journals (Sweden)

    Dongxiao Niu

    2018-01-01

    Full Text Available The electric power industry is of great significance in promoting social and economic development and improving people’s living standards. Power grid construction is a necessary part of infrastructure construction, whose sustainability plays an important role in economic development, environmental protection and social progress. In order to effectively evaluate the sustainability of power grid construction projects, in this paper, we first identified 17 criteria from four dimensions including economy, technology, society and environment to establish the evaluation criteria system. After that, the grey incidence analysis was used to modify the traditional Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS, which made it possible to evaluate the sustainability of electric power construction projects based on visual angle of similarity and nearness. Then, in order to simplify the procedure of experts scoring and computation, on the basis of evaluation results of the improved TOPSIS, the model using Modified Fly Optimization Algorithm (MFOA to optimize the Least Square Support Vector Machine (LSSVM was established. Finally, a numerical example was given to demonstrate the effectiveness of the proposed model.

  18. The Bearingless Electrical Machine

    Science.gov (United States)

    Bichsel, J.

    1992-01-01

    Electromagnetic bearings allow the suspension of solids. For rotary applications, the most important physical effect is the force of a magnetic circuit to a high permeable armature, called the MAXWELL force. Contrary to the commonly used MAXWELL bearings, the bearingless electrical machine will take advantage of the reaction force of a conductor carrying a current in a magnetic field. This kind of force, called Lorentz force, generates the torque in direct current, asynchronous and synchronous machines. The magnetic field, which already exists in electrical machines and helps to build up the torque, can also be used for the suspension of the rotor. Besides the normal winding of the stator, a special winding was added, which generates forces for levitation. So a radial bearing, which is integrated directly in the active part of the machine, and the motor use the laminated core simultaneously. The winding was constructed for the levitating forces in a special way so that commercially available standard ac inverters for drives can be used. Besides wholly magnetic suspended machines, there is a wide range of applications for normal drives with ball bearings. Resonances of the rotor, especially critical speeds, can be damped actively.

  19. Comparison of Survival and Safety Requirements in European Union for Recreational Craft Inspections. A Spanish Case Study

    Directory of Open Access Journals (Sweden)

    J. Torralbo

    2014-03-01

    Full Text Available Statistical data shows that a large number of maritime accidents are related to recreational craft. For instance, in Spain, more than fifty percent of the emergencies are related to pleasure boats at sea. Recreational craft marketed in the EU must comply with harmonized technical safety and environmental requirements defined by Directive 94/25/EC, as amended in 2003. On 28 December 2013, the new recreational craft directive 2013/53/EU was published in the Official Journal of the European Union. EU Member States have until 18 January 2016 to amend their national legislation and transpose the new directive. The current directive 94/25/EC as amended by directive 2003/44/EC will be repealed on 18 January 2016, after the full application of the new text. Although this directive, there is not a clear coordination and equivalence among the EU countries according to the survival and safety equipment compulsory for recreational crafts. The main purpose of this paper is to analyze and compare the types of survey / inspections to be carried in pleasure craft (non-commercial use, periodicity and required safety equipment in some member states of the European Union. A case study of Spain is presented. From the results obtained, we can make clear that in the European Union there is a lack of coordination in this area and indicate the need to unify a common pattern in inspections and survival and safety requirements of recreational boats in the EU.

    The distribution of spherical weathered bodies (commonly known as "boulder") in the granite development area directly affects the shield construction of urban rail transit engineering. This paper is based on the case of shield construction of granite globular development area in Southern China area, the parameter control in shield machine selection and shield advancing during the shield tunneling in this special geological environment is analyzed. And it is suggested that shield machine should be selected for shield construction of granite spherical weathered zone. Driving speed, cutter torque, shield machine thrust, the amount of penetration and the speed of the cutter head of shield machine should be controlled when driving the boulder formation, in order to achieve smooth excavation and reduce the disturbance to the formation.

  2. Noble gas control room accident filtration system for severe accident conditions (N-CRAFT)

    International Nuclear Information System (INIS)

    Hill, Axel; Stiepani, Cristoph; Drechsler, Michael

    2015-01-01

    Severe accidents might cause the release of airborne radioactive substances to the environment of the NPP either due to containment leakages or due to intentional filtered containment venting. In the latter case aerosols and iodine are retained, however noble gases are not retainable by the FCVS or by conventional air filtration systems like HEPA filters and iodine absorbers. Radioactive noble gases nevertheless dominate the activity release depending on the venting procedure and the weather conditions. To prevent unacceptable contamination of the control room atmosphere by noble gases, AREVA GmbH has developed a noble gas control room accident filtration system (CRAFT) which can supply purified fresh air to the control room without time limitation. The retention process is based on dynamic adsorption of noble gases on activated carbon. The system consists of delay lines (carbon columns) which are operated by a continuous and simultaneous adsorption and desorption process. CRAFT allows minimization of the dose rate inside the control room and ensures low radiation exposure to the staff by maintaining the control room environment suitable for prolonged occupancy throughout the duration of the accident. CRAFT consists of a proven modular design either transportable or permanently installed. (author)

    The study evaluates methodology employed for the projection of labor demand at, and worker migration to, nuclear power plant construction sites. In addition, suggestions are offered as to how this projection methodology might be improved. The study focuses on projection methodologies which forecast either construction worker migration or labor requirements of alternative types of construction activity. Suggested methodological improvements relate both to institutional factors within the nuclear power plant construction industry, and to a better use of craft-specific data on construction worker demand/supply. In addition, the timeliness and availability of the regional occupational data required to support, or implement these suggestions are examined

    1989-01-01

    The aim of this paper is to present the types of injury caused by firewood splitting machines and also to elucidate the accident mechanism. The study is based on 15 cases. The machine has a rotating spiral cone, and usually the victims' gloved fingertips were caught by the point of the cone. This led to either amputations, usually of radial fingers and/or penetrating wounds through the middle of the hand. In most cases the accidents could not be blamed on bad working techniques. The study of the mechanisms of injury points to insufficient protective devices in a machine construction which has a potentially dangerous working principle.

    Full Text Available Orientation: Knowing that it is imperative to better understand the antecedents and consequences of needs-supplies fit, the present research had two main objectives. Firstly we wanted to extend our knowledge about traditional psychological needs, for example highlighted through the Self-Determination Theory, by presenting more specific work-related needs. Secondly, following the new directions of organisational fit theories, we wanted to better understand how individuals make sense of fit. Research purpose: The purpose of this study is to propose more specific work-related needs in terms of employment quality and to test job crafting as an antecedent of needs-supplies fit (NS fit. We tested the double mediating role of NS fit (i.e. specific: based on more specific work-related needs, and general: based on global job perceptions between job crafting and individual outcomes namely burnout and work engagement. Motivation for the study: By taking into account more specific work-related needs, this study aimed to add more specific information to better help predict well-being at work. Moreover, the present research responds to the need to better understand how individuals make sense of fit. Research design, approach, and method: Data were collected in a Belgian Public Federal Service (N = 1500. Our research model was tested using Structural Equation Modelling with Mplus. Main findings: Results show, (1 that specific NS fit perception was positively related to a global NS fit perception and (2 the partial mediating role (specific and general of NS fit between job crafting and burnout and work engagement. Practical/managerial implications: Managers should encourage crafting behaviours and should know their team and that team’s specific needs. Contribution/added-value: By taking into account more specific work-related needs, our study suggests that needs-supplies may have more than one dimension. Moreover, it shows that job crafting is a way to

    We present a logical correspondence between natural semantics and abstract machines. This correspondence enables the mechanical and fully-correct construction of an abstract machine from a natural semantics. Our logical correspondence mirrors the Reynolds functional correspondence, but we...... manipulate semantic specifications encoded in a logical framework instead of manipulating functional programs. Natural semantics and abstract machines are instances of substructural operational semantics. As a byproduct, using a substructural logical framework, we bring concurrent and stateful models...

    The success of the radio-frequency quadrupole (RFQ) proof-of-principle (POP) tests conducted in 1980 at Los Alamos have essentially guaranteed that the RFQ linac will be used in many accelerator projects soon. Several RFQs are already under construction at Los Alamos, and we expect to be designing and machining the vanes for several RFQs to be built at other installations. The technique for machining the vanes for the POP RFQ was developed by Williams and Potter. While retaining their basic approach, we have modified their technique for generating the data required by the milling machine from the parameters defining the vane shapes. The objective of this exercise has been to develop a generalized fabrication procedure that could be used in commercial machine shops

    1984-01-01

    This paper describes the connection machine, a programmable computer based on cellular automata. The essential idea behind the connection machine is that a regular locally-connected cellular array can be made to behave as if the processing cells are connected into any desired topology. When the topology of the machine is chosen to match the topology of the application program, the result is a fast, powerful computing engine. The connection machine was originally designed to implement knowledge retrieval operations in artificial intelligence programs, but the hardware and the programming techniques are apparently applicable to a much larger class of problems. A machine with 100000 processing cells is currently being constructed. 27 references.

    The concept of a double-fed machine as an asynchronous motor with a phase rotor and a source of additional voltage is defined. Based on the analysis of a circuit replacing the double-fed machine, an expression is derived relating the moment, slip, amplitude and phase of additional voltage across the rotor. The conditions maximizing the moment with respect to amplitude and phase of additional voltage in the rotor circuit are also obtained, the phase surface of function of machine electromagnetic moment is constructed. The analysis of basic equation of electric drive motion in relation to electric drive of mine hoisting installations and the conclusion about the necessity of work in all four quadrants of coordinate plane “moment-slip” are made. Family of mechanical characteristics is constructed for a double-fed machine and its achievable speed control range in asynchronous mode is determined. Based on the type of mechanical characteristics and the calculated range of speed control, the conclusion is made about the suitability of using a dual-fed asynchronous machine for driving mine mechanisms with a small required speed control range and the need for organizing a combined operating mode for driving mine hoisting installations and other mechanisms with a large speed control range.

    2012-01-01

    Traditional approach on ship design involve the use of a method which takes a form that was earlier called the 'general design diagram' and is now known as the 'design spiral' – an iterative ship design process that allows for an increase in complexity and precision across the design cycle. Several advancements have been made towards the design spiral, however inefficient for handling complex simultaneous design changes, especially when later variable changes affect the ship's performance characteristics evaluated in earlier stages. Reviewed in this paper are several advancements in high speed planing craft design in preliminary design stage. An optimization framework for high speed planing craft is discussed which consist of surface information retrieval module, a suite of state-of-the-art optimization algorithms and standard naval architectural performance estimation tools. A summary of the implementation of the proposed hull surface information retrieval and several case studies are presented to demonstrate the capabilities of the framework.

    1998-01-01

    Full text: Lanthanum, ytterbium and scandium salts of trifluoromethanesulfonic acid have been shown to act as promising Lewis acid catalysts for the Friedel-Craft acylation reactions. In our study catalytic acylation of anisole by acetic anhydride in nitroethane was investigated. Yields were determined after extraction of para-methoxyacetophenone from the reaction mixture by G.L.C using the external standardisation method. Anhydrous lanthanoid tris-triflate salts [Ln(O 3 SCF 3 ) 3 , Ln La, Y, Nd, Eu and Yb] were initially investigated as catalysts. Ytterbium tris-triflate was found to be the most effective giving ∼90% of the acylation product. The hydrated lanthanide tris-nitrate salts [Ln(NO 3 ) 3 .nH 2 O, Ln = La, Nd, Eu and Yb] were also investigated using in situ dehydration with acetic anhydride. These were found to have low solubility in the reaction mixture and gave poor yields of para-methoxyacetophenone. The formation of side products was suggested by the low total recovery of anisole and para-methoxyacetophenone. The blocking of coordination sites of these catalysts by tetraglyme resulted in a 50% reduction in acylation activity compared with the simple salt. Addition of Li(O 3 SCF 3 ) to Ln(O 3 SCF 3 ) 3 catalysts (ratio of 4:1)had only a slight accelerating effect on the Friedel-Crafts acylation reaction and the yield was only marginally greater than that in the absence of the added salt. In contrast Li(ClO 4 ) dramatically decreased reaction times and improved the yield of para-methoxyace-tophenone, as recently reported

    To improve health outcomes and cut health care costs, we often need to conduct prediction/classification using large clinical datasets (aka, clinical big data), for example, to identify high-risk patients for preventive interventions. Machine learning has been proposed as a key technology for doing this. Machine learning has won most data science competitions and could support many clinical activities, yet only 15% of hospitals use it for even limited purposes. Despite familiarity with data, health care researchers often lack machine learning expertise to directly use clinical big data, creating a hurdle in realizing value from their data. Health care researchers can work with data scientists with deep machine learning knowledge, but it takes time and effort for both parties to communicate effectively. Facing a shortage in the United States of data scientists and hiring competition from companies with deep pockets, health care systems have difficulty recruiting data scientists. Building and generalizing a machine learning model often requires hundreds to thousands of manual iterations by data scientists to select the following: (1) hyper-parameter values and complex algorithms that greatly affect model accuracy and (2) operators and periods for temporally aggregating clinical attributes (eg, whether a patient's weight kept rising in the past year). This process becomes infeasible with limited budgets. This study's goal is to enable health care researchers to directly use clinical big data, make machine learning feasible with limited budgets and data scientist resources, and realize value from data. This study will allow us to achieve the following: (1) finish developing the new software, Automated Machine Learning (Auto-ML), to automate model selection for machine learning with clinical big data and validate Auto-ML on seven benchmark modeling problems of clinical importance; (2) apply Auto-ML and novel methodology to two new modeling problems crucial for care

    Gott has shown that a spacetime with two infinite parallel cosmic strings passing each other with sufficient velocity contains closed timelike curves. We discuss an attempt to build such a time machine. Using the energy-momentum conservation laws in the equivalent (2+1)-dimensional theory, we explicitly construct the spacetime representing the decay of one gravitating particle into two. We find that there is never enough mass in an open universe to build the time machine from the products of decays of stationary particles. More generally, the Gott time machine cannot exist in any open (2+1)-dimensional universe for which the total momentum is timelike

    Spanner, Matthew P.; Anderson, James A. D. W.

    2006-01-01

    The perspex machine arose from the unification of the Turing machine with projective geometry. The original, constructive proof used four special, perspective transformations to implement the Turing machine in projective geometry. These four transformations are now generalised and applied in a compiler, implemented in Pop11, that converts a subset of the C programming language into perspexes. This is interesting both from a geometrical and a computational point of view. Geometrically, it is interesting that program source can be converted automatically to a sequence of perspective transformations and conditional jumps, though we find that the product of homogeneous transformations with normalisation can be non-associative. Computationally, it is interesting that program source can be compiled for a Reduced Instruction Set Computer (RISC), the perspex machine, that is a Single Instruction, Zero Exception (SIZE) computer.

    The aim of this work was both to study the performances of pleasure craft reinforced components, bonded using a structural adhesive, and to compare them with those obtained using over-lamination as joining system, typically employed in the shipbuilding. With such aim, two different lots of components were prepared: in the first lot, the reinforcement structures were laminated directly on the investigated composite components and, in the second one; they were made separately in a mould and, then, bonded to the composite components. This last method allowed to evaluate the introduction of a product/process innovation in a field typically unwilling to innovation, still tied to craft, and non-standardized procedures. The results of bending tests, performed in order to evaluate the mechanical behaviour of the reinforced components, evidenced the goodness of this innovative design choice. Finally, a finite element analysis was performed. [Figure not available: see fulltext.

    2015-08-01

    The rather turbulent history of arthroscopic rotator cuff repair went through stages of innovation, conflict, disruption, assimilation, and transformation that might be anticipated when a new and advanced technology (arthroscopic cuff repair) displaces an entrenched but outdated discipline (open cuff repair). The transition from open to arthroscopic rotator cuff repair has been a major paradigm shift that has greatly benefited patients. However, this technical evolution/revolution has also imposed a higher "burden of craft" on the practitioners of arthroscopic rotator cuff repair. Technological advancements in surgery demand that surgeons accept this burden of craft and master the advanced technology for the benefit of their patients. This article outlines the author's involvement in the development of arthroscopic rotator cuff repair, and it also explores the surgeon's obligation to accept the burden of craft that is imposed by this discipline.

  8. Selling an Energy Efficiency Loan Portfolio in Oregon: Resale of the Craft3 loan portfolio to Self-Help Credit Union

    Thompson, Peter; Borgeson, Merrian; Kramer, Chris; Zimring, Mark; Goldman, Charles

    2014-05-30

    Under the Clean Energy Works (CEW) program, Craft3 developed a loan product that widened access to financing for homeowners, offered long term funding, and collected repayments through the customer?s utility bill. The program?s success led Craft3 to pursue the sale of the loan portfolio to both mitigate its own risks and replenish funds for lending. This sale breaks new ground for energy efficiency finance and is notable as it was completed even with many novel program design elements. It replenished Craft3?s program capital and uncovered some valuable lessons that may facilitate future transactions. However, the lack of data history and the unproven nature of the loan portfolio meant that Craft3 had to limit the risk of losses to Self-Help, the purchaser of the portfolio. It remains to be seen whether this experience will pave the way for more sales of on-bill energy efficiency loan portfolios. This case study illustrates how certain program design decisions can sometimes both facilitate programmatic objectives and possibly present challenges for the sale of a portfolio of energy efficiency loans.

    1993-03-01

    At the request of the US Department of Energy (DOE), a team from Oak Ridge National Laboratory conducted a radiological survey at the former Alba Craft Laboratory Site Properties, Oxford, Ohio. The survey was performed in July and September of 1992. The purpose of the survey was to determine whether the property was contaminated with radioactive residues, primarily 238 U, from uranium machining operations conducted for National Lead of Ohio, a prime Atomic Energy Commission contractor. The survey included scan measurement of direct radiation levels inside and outside the former laboratory, outdoors on eight properties adjoining the former laboratory, and the city right-of-way adjacent to the surveyed properties. Radionuclide concentrations were determined in outdoor surface and subsurface soil samples taken from each property and the exterior of the laboratory. Fixed surface residual radioactivity was measured inside the laboratory and outside the building. Air samples were collected, direct exposure was measured, and samples were collected to measure transferable radioactivity inside the building. Results of the survey indicate areas where surface and soil contamination level s are above the DOE guidelines for uncontrolled areas

    Niu, Haiqiang; Reeves, Emma; Gerstoft, Peter

    2017-09-01

    Source localization in ocean acoustics is posed as a machine learning problem in which data-driven methods learn source ranges directly from observed acoustic data. The pressure received by a vertical linear array is preprocessed by constructing a normalized sample covariance matrix and used as the input for three machine learning methods: feed-forward neural networks (FNN), support vector machines (SVM), and random forests (RF). The range estimation problem is solved both as a classification problem and as a regression problem by these three machine learning algorithms. The results of range estimation for the Noise09 experiment are compared for FNN, SVM, RF, and conventional matched-field processing and demonstrate the potential of machine learning for underwater source localization.

    This paper dwells upon a variance parameterization method. Variance or dimensional parameterization is based on sketching, with various parametric links superimposed on the sketch objects and user-imposed constraints in the form of an equation system that determines the parametric dependencies. This method is fully integrated in a top-down design methodology to enable the creation of multi-variant and flexible fixture assembly models, as all the modeling operations are hierarchically linked in the built tree. In this research the authors consider a parameterization method of machine tooling used for manufacturing parts using multiaxial CNC machining centers in the real manufacturing process. The developed method allows to significantly reduce tooling design time when making changes of a part’s geometric parameters. The method can also reduce time for designing and engineering preproduction, in particular, for development of control programs for CNC equipment and control and measuring machines, automate the release of design and engineering documentation. Variance parameterization helps to optimize construction of parts as well as machine tooling using integrated CAE systems. In the framework of this study, the authors demonstrate a comprehensive approach to parametric modeling of machine tooling in the CAD package used in the real manufacturing process of aircraft engines.

    2017-02-01

    Full Text Available Presented in this paper is a method for the design of modular reconfigurable machine tools (MRMTs. An MRMT is capable of using a minimal number of modules through reconfiguration to perform the required machining tasks for a family of parts. The proposed method consists of three steps: module identification, module determination, and layout synthesis. In the first step, the module components are collected from a family of general-purpose machines to establish a module library. In the second step, for a given family of parts to be machined, a set of needed modules are selected from the module library to construct a desired reconfigurable machine tool. In the third step, a final machine layout is decided though evaluation by considering a number of performance indices. Based on this method, a software package has been developed that can design an MRMT for a given part family.

    This paper reports that characterization of Yucca Mountain for a potential repository requires construction of an underground Exploratory Studies Facility (ESF). Mechanical excavating methods have been proposed for construction of the ESF as they offer a number of advantages over drilling and blasting at the Yucca Mountain site, including; less ground disturbance and therefore a potential for less adverse effects on the integrity of the site, creation of a more stable excavation cross section requiring less ground support, and an inherently safer and cleaner working environment. The tunnel boring machine (TBM) provides a proven technology for excavating the welded and unwelded Yucca Mountain tuffs. The access ramps and main underground tunnels form the largest part of the ESF underground construction work, and have been designed for excavation by TBM

  5. Overview of craft brewing specificities and potentially associated microbiota.

    Rodhouse, Lindsey; Carbonero, Franck

    2017-09-14

    The brewing process differs slightly in craft breweries as compared to industrial breweries, as there are fewer control points. This affects the microbiota of the final product. Beer contains several antimicrobial properties that protect it from pathogens, such as low pH, low oxygen and high carbon dioxide content, and the addition of hops. However, these hurdles have limited power controlling spoilage organisms. Contamination by these organisms can originate in the raw materials, persist in the environment, and be introduced by using flavoring ingredients later in the process. Spoilage is a prominent issue in brewing, and can cause quality degradation resulting in consumer rejection and product waste. For example, lactic acid bacteria are predominately associated with producing a ropy texture and haze, along with producing diacetyl which gives the beer butter flavor notes. Other microorganisms may not affect flavor or aroma, but can retard fermentation by consuming nutrients needed by fermentation yeast. Quality control in craft breweries today relies on culturing methods to detect specific spoilage organisms. Using media can be beneficial for detecting the most common beer spoilers, such as Lactobacillus and Pediococci. However, these methods are time consuming with long incubation periods. Molecular methods such as community profiling or high throughput sequencing are better used for identifying entire populations of beer. These methods allow for detection, differentiation, and identification of taxa.

    Implementing construction work that creates buildings is a very complicated and laborious task and requires the use of various types of machines and equipment. For years there has been a desire for designers and technologists to introduce devices that replace people’s work on machine construction, automation and even robots. Technologies for building construction are still being developed and implemented to limit people’s hard work and improve work efficiency and quality in innovative architectonical and construction solutions. New opportunities for improving work on the construction site include computerisation of technological processes and construction management for projects and processes. The aim of the paper was to analyse the development of mechanisation, automation and computerisation of construction processes and selected building technologies, with special attention paid to 3D printing technology. The state of mechanisation of construction works in Poland and trends in its development in construction technologies are presented. These studies were conducted on the basis of the available literature and a survey of Polish construction companies.

    2013-08-01

    Full Text Available Labor input in manual cassava chips processing is very high and product quality is low. This paper presents the design and construction of an electrically operated cassava slicing machine that requires only one person to operate. Efficiency, portability, ease of operation, corrosion prevention of slicing component of the machine, force required to slice a cassava tuber, capacity of 10 kg/min and uniformity in the size of the cassava chips were considered in the design and fabrication of the machine. The performance of the machine was evaluated with cassava of average length and diameter of 253 mm and 60 mm respectively at an average speed of 154 rpm. The machine produced 5.3 kg of chips of 10 mm length and 60 mm diameter in 1 minute. The efficiency of the machine was 95.6% with respect to the quantity of the input cassava. The chips were found to be well chipped to the designed thickness, shape and of generally similar size. Galvanized steel sheets were used in the cutting section to avoid corrosion of components. The machine is portable and easy to operate which can be adopted for cassava processing in a medium size industry.

  12. Using Machine Learning to Search for MSSM Higgs Bosons

    CERN Document Server

    Diesing, Rebecca

    2016-01-01

    This paper examines the performance of machine learning in the identification of Minimally Su- persymmetric Standard Model (MSSM) Higgs Bosons, and compares this performance to that of traditional cut strategies. Two boosted decision tree algorithms were tested, scikit-learn and XGBoost. These tests indicated that machine learning can perform significantly better than traditional cuts. However, since machine learning in this form cannot be directly implemented in a real MSSM Higgs analysis, this performance information was instead used to better understand the relationships between training variables. Further studies might use this information to construct an improved cut strategy.

    1994-01-01

    Full Text Available Many programming models for massively parallel machines exist, and each has its advantages and disadvantages. In this article we present a programming model that combines features from other programming models that (1 can be efficiently implemented on present and future Cray Research massively parallel processor (MPP systems and (2 are useful in constructing highly parallel programs. The model supports several styles of programming: message-passing, data parallel, global address (shared data, and work-sharing. These styles may be combined within the same program. The model includes features that allow a user to define a program in terms of the behavior of the system as a whole, where the behavior of individual tasks is implicit from this systemic definition. (In general, features marked as shared are designed to support this perspective. It also supports an opposite perspective, where a program may be defined in terms of the behaviors of individual tasks, and a program is implicitly the sum of the behaviors of all tasks. (Features marked as private are designed to support this perspective. Users can exploit any combination of either set of features without ambiguity and thus are free to define a program from whatever perspective is most appropriate to the problem at hand.

  15. Experimental studies of the rotor flow downwash on the Stability of multi-rotor crafts in descent

    2017-11-01

    All rotorcrafts, including helicopters and multicopters, have the inherent problem of entering rotor downwash during vertical descent. As a result, the craft is subject to highly unsteady flow, called vortex ring state (VRS), which leads to a loss of lift and reduced stability. To date, experimental efforts to investigate this phenomenon have been largely limited to analysis of a single, fixed rotor mounted in a horizontal wind tunnel. Our current work aims to understand the interaction of multiple rotors in vertical descent by mounting a multi-rotor craft in a low speed, vertical wind tunnel. Experiments were performed with a fixed and rotationally free mounting; the latter allowing us to better capture the dynamics of a free flying drone. The effect of rotor separation on stability, generated thrust, and rotor wake interaction was characterized using force gauge data and PIV analysis for various descent velocities. The results obtained help us better understand fluid-craft interactions of drones in vertical descent and identify possible sources of instability. The presented material is based upon work supported by the Center for Autonomous Systems and Technologies (CAST) at the Graduate Aerospace Laboratories of the California Institute of Technology (GALCIT).

    Anslan, Sten; Bahram, Mohammad; Hiiesalu, Indrek; Tedersoo, Leho

    2017-11-01

    High-throughput sequencing methods have become a routine analysis tool in environmental sciences as well as in public and private sector. These methods provide vast amount of data, which need to be analysed in several steps. Although the bioinformatics may be applied using several public tools, many analytical pipelines allow too few options for the optimal analysis for more complicated or customized designs. Here, we introduce PipeCraft, a flexible and handy bioinformatics pipeline with a user-friendly graphical interface that links several public tools for analysing amplicon sequencing data. Users are able to customize the pipeline by selecting the most suitable tools and options to process raw sequences from Illumina, Pacific Biosciences, Ion Torrent and Roche 454 sequencing platforms. We described the design and options of PipeCraft and evaluated its performance by analysing the data sets from three different sequencing platforms. We demonstrated that PipeCraft is able to process large data sets within 24 hr. The graphical user interface and the automated links between various bioinformatics tools enable easy customization of the workflow. All analytical steps and options are recorded in log files and are easily traceable. © 2017 John Wiley & Sons Ltd.

    Pristup, A. G.; Toporkov, D. M.

    2017-10-01

    The results of the investigation of the cogging torque in permanent magnet synchronous machines, which is caused by the stator slotting and the rotor eccentricity, are presented in the paper. A new design of the machine has been developed in the course of the investigation, and the value of the cogging torque in this construction is less considerably compared to other constructions. In contrast to the available methods of the cogging torque reduction, the solution suggested not only decreases the level of the cogging torque but also has negligibly small influence on characteristics of the machine with the rotor eccentricity which is typical of the mass production and long-term usage.

  1. Homopolar machine design

    International Nuclear Information System (INIS)

    Thullen, P.

    1978-01-01

    A general conceptual design for a disc-type homopolar machine is presented. This machine uses a superconducting, air-core, solenoidal field winding with a peak field of 8 T. A total energy of 500 MJ is stored in two counter-rotating disc rotors that operate at a surface speed of 200 m/s. Terminal voltages of 500 to 2000 V are obtained over the range of designs studied. Brush systems to collect 3 MA are investigated. Various brush materials are discussed to determine their usefulness in this application. Sufficient information on operating characteristics in high-power applications is only available for copper-graphite brushes. The use of sliding brushes for terminal voltage regulation is discussed. This feature cannot provide a great deal of flexibility in this particular application although it may be useful during start-up. The brush system is the most demanding feature of this design. Few systems in the million ampere range have been constructed, consequently, it is not possible to predict the behavior of this brush system with great certainty. A detailed design of the brushes should be undertaken. It is estimated that the cost of such a machine will range from 0.5 to 1.5 cents per joule

  2. Design Of A Small-Scale Hulling Machine For Improved Wet-Processed Coffee.

    Directory of Open Access Journals (Sweden)

    Adeleke

    2017-08-01

    Full Text Available The method of primary processing of coffee is a vital determinant of quality and price. Wet processing method produces higher quality beans but is very labourious. This work outlines the design of a small scale cost-effective ergonomic and easily maintained and operated coffee hulling machine that can improve quality and productivity of green coffee beans. The machine can be constructed from locally available materials at a relatively low cost of about NGN 140000.00 with cheap running cost. The beaters are made from rubber strip which can deflect when in contact with any obstruction causing little or no stresses on drum members and reducing the risk of damage to both the beans and machine. The machine is portable and detachable which make it fit to be owned by a group of farmers who can move it from one farm to the other making affordability and running cost easier. The easily affordable and relatively low running cost may be further reduced by the fact that the machine is powered by 3.0 Hp petrol engine which is suitable for other purposes among the rural dwellers. The eventual construction of the machine will encourage more farmers to go into wet processing of coffee and reduce the foreign exchange hitherto lost to this purpose.

    We propose a self-replicating machine that is embedded in a two-dimensional asynchronous cellular automaton with von Neumann neighborhood. The machine dynamically encodes its shape into description signals, and despite the randomness of cell updating, it is able to successfully construct copies of itself according to the description signals. Self-replication on asynchronously updated cellular automata may find application in nanocomputers, where reconfigurability is an essential property, since it allows avoidance of defective parts and simplifies programming of such computers.

    2015-01-01

    Full Text Available The setting of parameters in the support vector machines (SVMs is very important with regard to its accuracy and efficiency. In this paper, we employ the firefly algorithm to train all parameters of the SVM simultaneously, including the penalty parameter, smoothness parameter, and Lagrangian multiplier. The proposed method is called the firefly-based SVM (firefly-SVM. This tool is not considered the feature selection, because the SVM, together with feature selection, is not suitable for the application in a multiclass classification, especially for the one-against-all multiclass SVM. In experiments, binary and multiclass classifications are explored. In the experiments on binary classification, ten of the benchmark data sets of the University of California, Irvine (UCI, machine learning repository are used; additionally the firefly-SVM is applied to the multiclass diagnosis of ultrasonic supraspinatus images. The classification performance of firefly-SVM is also compared to the original LIBSVM method associated with the grid search method and the particle swarm optimization based SVM (PSO-SVM. The experimental results advocate the use of firefly-SVM to classify pattern classifications for maximum accuracy.

    The Landing Craft Air Cushion is a high-speed, over-the-beach, fully amphibious landing craft capable of carrying a 60-75 ton payload. The LCAC fleet can serve to transport weapons systems, equipment, cargo and personnel from ship to shore and across the beach. This transport system is an integral part of our military arsenal and, as such, its readiness is an important consideration for our national security. Further, the best way to expend financial resources that have been allocated to maintain this fleet is a critical Issue. There is a clear coupling between the measure of Fleet Readiness as defined by the customer for this project and the information that is provided by Sandia's ProOpta methodology. Further, there is a richness in the data that provides even more value to the analyst. This report provides an analytic framework for understanding the connection between Fleet Readiness and the output provided by Sandia's ProOpta software. Further, this report highlights valuable information that can also be made available using the ProOpta output and concepts from basic probability theory. Finally, enabling assumptions along with areas that warrant consideration for further study are identified.

The author historically locates current debates around craft production and creative work by drawing upon the British Arts and Crafts movement, with its own longstanding association with women's' labour in the home and desire to realise sustainable ethical labour practices. Notably, both the periods under discussion mark profound shifts in the economic organisation of society – then, the Industrial Revolution; now the de-industrialisation of much of the 'industrialised' world and the rise of the (digitised knowledge economy – and see a concurrent increase in the popularity of the handmade original as a desirable aesthetic object.

    2001-01-01

    To eliminate the early failures and improve the reliability, nine ex-factory machining centers are traced under field conditions in workshops. Their early failure information throughout the ex-factory run-in test is collected. The field early failure database is constructed based on the collection of field early failure data and the codification of data. Early failure mode and effects analysis is performed to indicate the weak subsystem of a machining center or the troublemaker. The distribution of the time between early failures is analyzed and the optimal ex-factory run-in test time for machining center that may expose sufficiently the early failures and cost minimum is discussed. Suggestions how to arrange ex-factory run-in test and how to take actions to reduce early failures for machining center is proposed

    1981-01-01

    In the X-ray optical system for the photon factory facility being constructed now in the National Laboratory for High Energy Physics, total reflection mirrors occupy important position. The shapes of mirrors are both plane and curved surface, and the sizes are various. Especially concerning hard X-ray, the required accuracy of the shapes and surface roughness is high. Thereupon mirrors were machined by elastic emission machining (EEM) developed by Mori et al. of Osaka University, and the flatness and surface roughness were examined. The materials machined were Pyrex and copper, the mirror finish of which is difficult. The results are reported. In this machining method, the liquid in which very fine powder is uniformly dispersed and suspended in water was used. By approaching a rotating urethane ball to a work surface, the gap of about 1 μm was formed between them utilizing fluid bearing-like flow arising there. The machining was carried out by colliding the fine particles in suspension to a minute region of the work surface. In order to obtain an arbitrary curved surface, the numerical control according to the variable controling the amount of machining was made. In the case of glasses, the amount of machining was able to be controlled to about 0.01 μm. As for polycrystalline copper, the machining was difficult, and the suitable conditions must be sought hereafter. (Kako, I.)

    Due to the recent increase in world energy demand, construction of considerable number of nuclear and fossil power plant has been proceeded and is further planned. High generating capacity plant requires large forged components such as monoblock turbine rotor shafts and the dimensions of them tend to increase. Some of these components have center bore for material test, NDE and other use. In order to cope with the increase in production of these large forgings with center bores, a new trepanning machine, which exclusively bore a deep hole, was developed in JSW taking account of many accumulated experiences and know-how of experts. The machine is the world largest 400t trepanning and horning machine with numerical control and has many advantage in safety, the machining precision, machining efficiency, operability, labor-saving, and energy saving. Furthermore, transfer of the technical skill became easy through concentrated monitoring system based on numerically analysed experts' know-how. (author)

    1982-01-01

    A new reacting plasma machine is designed, and will be constructed at the Institute of Plasma Physics, Nagoya University. It is important to avoid the activation of the materials for the machine, accordingly, aluminum alloy has been considered as the material since the induced activity of aluminum due to 14 MeV neutrons is small. The vacuum chamber of the new machine consists of four modules, and the remote control of each module is considered. However, the cost of the remote control of modules is expensive. To minimize the dependence on the remote control, the use of aluminum alloy is considered as the first step. The low electrical resistivity, over-ageing, weak mechanical strength and eddy current characteristics of aluminum alloy must be improved. The physical and electrical properties of various aluminum alloys have been investigated. Permeability of hydrogen through aluminum, the recycling characteristics and surface coating materials have been also studied. (Kato, T.)

  3. Construction of a universal quantum computer

    2009-01-01

    We construct a universal quantum computer following Deutsch's original proposal of a universal quantum Turing machine (UQTM). Like Deutsch's UQTM, our machine can emulate any classical Turing machine and can execute any algorithm that can be implemented in the quantum gate array framework but under the control of a quantum program, and hence is universal. We present the architecture of the machine, which consists of a memory tape and a processor and describe the observables that comprise the registers of the processor and the instruction set, which includes a set of operations that can approximate any unitary operation to any desired accuracy and hence is quantum computationally universal. We present the unitary evolution operators that act on the machine to achieve universal computation and discuss each of them in detail and specify and discuss explicit program halting and concatenation schemes. We define and describe a set of primitive programs in order to demonstrate the universal nature of the machine. These primitive programs facilitate the implementation of more complex algorithms and we demonstrate their use by presenting a program that computes the NAND function, thereby also showing that the machine can compute any classically computable function.

    To create a solution for a specific problem in machine learning, the solution is constructed from the data or by use a search method. Genetic algorithms are a model of machine learning that can be used to find nearest optimal solution. While the great advantage of genetic algorithms is the fact that they find a solution through evolution, this is also the biggest disadvantage. Evolution is inductive, in nature life does not evolve towards a good solution but it evolves aw...

    2015-07-01

    We have designed and constructed a new system for micro-machining parts and sample assemblies used for diamond anvil cells and general user operations at the High Pressure Collaborative Access Team, sector 16 of the Advanced Photon Source. The new micro-machining system uses a pulsed laser of 400 ps pulse duration, ablating various materials without thermal melting, thus leaving a clean edge. With optics designed for a tight focus, the system can machine holes any size larger than 3 μm in diameter. Unlike a standard electrical discharge machining drill, the new laser system allows micro-machining of non-conductive materials such as: amorphous boron and silicon carbide gaskets, diamond, oxides, and other materials including organic materials such as polyimide films (i.e., Kapton). An important feature of the new system is the use of gas-tight or gas-flow environmental chambers which allow the laser micro-machining to be done in a controlled (e.g., inert gas) atmosphere to prevent oxidation and other chemical reactions in air sensitive materials. The gas-tight workpiece enclosure is also useful for machining materials with known health risks (e.g., beryllium). Specialized control software with a graphical interface enables micro-machining of custom 2D and 3D shapes. The laser-machining system was designed in a Class 1 laser enclosure, i.e., it includes laser safety interlocks and computer controls and allows for routine operation. Though initially designed mainly for machining of the diamond anvil cell gaskets, the laser-machining system has since found many other micro-machining applications, several of which are presented here.

    Riva, M A; Cesana, G; Mosconi, G

    2012-01-01

    Construction has been one of the first sectors in which an organized system of occupational health protection has been implemented, as shown by the Egyptian physicians caring for workers and artisans in building sites. During the Middle Ages, first examples of accident prevention legislation in this field may be found among the Lombards. In the same period, craft organizations led to greater social recognition of skilled workers, without a improvement in their health conditions. Ramazzini accurately described some risks of stonemasons and brick-makers (chemical and microclimatic hazards). In the following centuries, the Industrial Revolution led to a population growth in metropolitan areas and increased employment as well as accidents in the construction sector, as demonstrated by some ex-voto paintings in churches. This phenomenon became more evident in postwar recovery, forcing Italy to adopt modern accident prevention rules. Nowadays Italian legislation, complying with EU directive, provides new challenges for occupational physician.

    Full Text Available Aim. The aim of this study is to create and represent the tourist routes in the places of the traditional folk arts and crafts in the Republic of Dagestan.Research Methodology. In the first stage of the study, according to the register and public materials we identified and studied traditional places of folk arts and crafts; carried out monitoring of existing tourist routes and programs. Developed routes are included in the tourist route map.Findings and discussion. We developed five radial exit routes from the city of Makhachkala, characteristics of which are presented below. Folk arts and crafts of Dagestan are a unique part of the artistic culture and at the same time, it is a branch of industry with a high level of tourist attractiveness. Today, Dagestan is one of the few areas in the modern world where traditional folk art is naturally a part of a contemporary social life having the rights of the dominant cultural unity due to the peculiarities of its historical development. Archaeological studies show that due to the geographical position, in Dagestan, there has been an interaction of significant aspects of cultural phenomena relating to the ancient civilizations of the Mediterranean, Western, Central and Eastern Europe, on the one hand, and the development of cultures of different regions of Asia, on the other hand. Coupled with the traditions of the ancient population of the Caucasus, they formed complex and varied artistic conglomerate.Conclusion. The study revealed the basic centers of traditional arts and crafts of the Republic of Dagestan, hiving a high tourism potential. On this basis, we developed five tourist-excursion routes. These routes are included in the information booklet, which has a marketing and information value.

    Gonyeau, J.A.; Long, R.E.

    1985-01-01

    Northern States Power Company is making a major effort to develop performance based training. It is finding the use of JTA data very helpful in the revision of its maintenance craft training programs. The technique being used involves a group of interns from the Training and Development Program of the University of Minnesota. These interns are largely graduate students, but with no nuclear and little mechanical/electrical experience. A Job Analysis for each discipline was used to: guide the following task analysis, determine program content, evaluate existing OJT check lists, and to define the four crafts used for mechanical maintenance. From the Job Analysis, a Training Task List was developed and correlated to training materials. The analysis of the tasks on the Training Task List is proceeding. Taxonomies of systems or subjects are compared to existing lesson plans. These taxonomies are useful when writing new lesson plans. The taxonomies are an excellent start for the development of enabling objectives. A Nine-Step Plan is being followed in the application of JTA data to the development and refinement of performance based training

  20. Embryonic expression of shuttle craft, a Drosophila gene involved in neuron development, is associated with adult lifespan.

    2014-12-01

    Despite the progress in aging research that highlights the role of the nervous system in longevity, whether genes that control development and consequently structure of the nervous system affect lifespan is unclear. We demonstrated that a mutation inshuttle craft, a gene involved in the nervous system development, increased the lifespan of unmated females and decreased the lifespan of mated females, without affecting males. Precise reversions of the mutation lead to the restoration of the lifespan specific to control females. In mutant unmated females, increased lifespan was associated with elevated locomotion at older ages, indicating slowed aging. In mutant mated females, reproduction was decreased compared to controls, indicating a lack of tradeoff between this trait and lifespan. No differences in shuttle craft transcription were observed between whole bodies, ovaries, and brains of mutant and control females of different ages, either unmated or mated. The amount of shuttle craft transcript appeared to be substantially decreased in mutant embryos. Our results demonstrated that a gene that regulates development of the nervous system might also influence longevity, and thus expanded the spectrum of genes involved in lifespan control. We hypothesize that this "carry-over" effect might be the result of transcription regulation in embryos.
