  6. Teaching machines to find mantle composition

    Science.gov (United States)

    Atkins, Suzanne; Tackley, Paul; Trampert, Jeannot; Valentine, Andrew

    2017-04-01

    The composition of the mantle affects many geodynamical processes by altering factors such as the density, the location of phase changes, and melting temperature. The inferences we make about mantle composition also determine how we interpret the changes in velocity, reflections, attenuation and scattering seen by seismologists. However, the bulk composition of the mantle is very poorly constrained. Inferences are made from meteorite samples, rock samples from the Earth and inferences made from geophysical data. All of these approaches require significant assumptions and the inferences made are subject to large uncertainties. Here we present a new method for inferring mantle composition, based on pattern recognition machine learning, which uses large scale in situ observations of the mantle to make fully probabilistic inferences of composition for convection simulations. Our method has an advantage over other petrological approaches because we use large scale geophysical observations. This means that we average over much greater length scales and do not need to rely on extrapolating from localised samples of the mantle or planetary disk. Another major advantage of our method is that it is fully probabilistic. This allows us to include all of the uncertainties inherent in the inference process, giving us far more information about the reliability of the result than other methods. Finally our method includes the impact of composition on mantle convection. This allows us to make much more precise inferences from geophysical data than other geophysical approaches, which attempt to invert one observation with no consideration of the relationship between convection and composition. We use a sampling based inversion method, using hundreds of convection simulations run using StagYY with self consistent mineral physics properties calculated using the PerpleX package. The observations from these simulations are used to train a neural network to make a probabilistic inference

  7. Discovering phases, phase transitions, and crossovers through unsupervised machine learning: A critical examination

    Science.gov (United States)

    Hu, Wenjian; Singh, Rajiv R. P.; Scalettar, Richard T.

    2017-06-01

    We apply unsupervised machine learning techniques, mainly principal component analysis (PCA), to compare and contrast the phase behavior and phase transitions in several classical spin models—the square- and triangular-lattice Ising models, the Blume-Capel model, a highly degenerate biquadratic-exchange spin-1 Ising (BSI) model, and the two-dimensional X Y model—and we examine critically what machine learning is teaching us. We find that quantified principal components from PCA not only allow the exploration of different phases and symmetry-breaking, but they can distinguish phase-transition types and locate critical points. We show that the corresponding weight vectors have a clear physical interpretation, which is particularly interesting in the frustrated models such as the triangular antiferromagnet, where they can point to incipient orders. Unlike the other well-studied models, the properties of the BSI model are less well known. Using both PCA and conventional Monte Carlo analysis, we demonstrate that the BSI model shows an absence of phase transition and macroscopic ground-state degeneracy. The failure to capture the "charge" correlations (vorticity) in the BSI model (X Y model) from raw spin configurations points to some of the limitations of PCA. Finally, we employ a nonlinear unsupervised machine learning procedure, the "autoencoder method," and we demonstrate that it too can be trained to capture phase transitions and critical points.

    2013-05-01

    Full Text Available Maintenance of electric machines and installations is a particularly important area; eventual faults in these devices may lead to significant losses in terms of time and money. The investment and concern in developing proper maintenance protocols have been gradually increasing over recent decades. As a consequence, there is a need to instruct future engineers in the electric machines and installations maintenance area. The subject "Maintenance of Electric Machines and Installations" has been designed under this idea. It is taught within an official master degree in Maintenance Engineering. This work describes the educational experiences reached during the initial years of the teaching of the subject. Aspects such as student profiles, subject approaches, design of the syllabus, methodology and structure of the laboratory sessions are remarked in the work. In addition, the paper discusses other educational strategies which are being introduced to increase the interest in the subject, such as integration of Information and Communication Technologies (ICT, promotion of the collaborative work, inclusion of the possibility of remote learning or development of new assessment systems.

  13. Teaching About Sound: A Select Historical Examination of Research

    Science.gov (United States)

    McGinnis, J. Randy; Oliver, J. Steve

    The teaching of the science topic sound, a popular topic in science instruction, is selectively analyzed over the past century using evidence excerpted from a prominent teacher practitioner journal (School Science And Mathematics). Shifting innovative recommendations on how teachers of science should teach the sound topic are identified in the categories of content and pedagogy. Historical connections to the scientific development of sound, identification of what constitutes the subject matter of sound, recommended general pedagogical strategies, and best practices for teaching strategies associated with the sound concept are examined. Discussion relates to the influence of contextual factors in a given time period (social and theoretical) on the design of curriculum materials used to guide instructional practice. One implication for science teacher education is the need for science teachers to develop an historically and philosophically grounded perspective by examining both the teaching practices on a science topic over an extended time and the historical scientific development of the science topic.

    2013-12-15

    Recent advances in microscope automation provide new opportunities for high-throughput cell biology, such as image-based screening. High-complex image analysis tasks often make the implementation of static and predefined processing rules a cumbersome effort. Machine-learning methods, instead, seek to use intrinsic data structure, as well as the expert annotations of biologists to infer models that can be used to solve versatile data analysis tasks. Here, we explain how machine-learning methods work and what needs to be considered for their successful application in cell biology. We outline how microscopy images can be converted into a data representation suitable for machine learning, and then introduce various state-of-the-art machine-learning algorithms, highlighting recent applications in image-based screening. Our Commentary aims to provide the biologist with a guide to the application of machine learning to microscopy assays and we therefore include extensive discussion on how to optimize experimental workflow as well as the data analysis pipeline.

    The recent change in innovation and employments of high-temperature magnets, permanent magnet flux switching machine (PMFSM) has turned out to be one of the suitable contenders for seaward boring, however, less intended for downhole because of high atmospheric temperature. Subsequently, this extensive review manages the design enhancement and performance examination of external rotor PMFSM for the downhole application. Preparatory, the essential design parameters required for machine configuration are computed numerically. At that point, the design enhancement strategy is actualized through deterministic technique. At last, preliminary and refined execution of the machine is contrasted and as a consequence, the yield torque is raised from 16.39Nm to 33.57Nm while depreciating the cogging torque and PM weight up to 1.77Nm and 0.79kg, individually. In this manner, it is inferred that purposed enhanced design of 12slot-22pole with external rotor is convenient for the downhole application.

    To most people, the log file would not be considered an exciting area in technology today. However, these relatively benign, slowly growing data sources can drive large business transformations when combined with modern-day analytics. Accenture Technology Labs has built a new framework that helps to expand existing vendor solutions to create new methods of gaining insights from these benevolent information springs. This framework provides a systematic and effective machine-learning mechanism to understand, analyze, and visualize heterogeneous log files. These techniques enable an automated approach to analyzing log content in real time, learning relevant behaviors, and creating actionable insights applicable in traditionally reactive situations. Using this approach, companies can now tap into a wealth of knowledge residing in log file data that is currently being collected but underutilized because of its overwhelming variety and volume. By using log files as an important data input into the larger enterprise data supply chain, businesses have the opportunity to enhance their current operational log management solution and generate entirely new business insights-no longer limited to the realm of reactive IT management, but extending from proactive product improvement to defense from attacks. As we will discuss, this solution has immediate relevance in the telecommunications and security industries. However, the most forward-looking companies can take it even further. How? By thinking beyond the log file and applying the same machine-learning framework to other log file use cases (including logistics, social media, and consumer behavior) and any other transactional data source.

  8. An examination of the relationship between teaching style and teaching philosophy

    Science.gov (United States)

    Snyder, Deborah Sue Aden

    Using both quantitative research methods along with a case study approach, this study sought to demonstrate that there is no difference between the teaching style and the philosophy of an experienced teacher. A teacher with a constructivist philosophy teaches using an inquiry-based approach in the classroom. A teacher with a didactic philosophy creates a teacher-centered classroom. In the early 1990s, the two teachers of this case study participated in the SALISH research project at IUP. At that time, both of these teachers were beginning teachers. This project examined teaching style and philosophy of beginning teachers. In both cases the teachers had a very constructivist philosophy of teaching, but their style did not reflect that philosophy. Their style was very much a teacher-centered style. They were in charge of the classroom and the students had very little input into the workings of the classroom. Participating in a similar study nearly 15 years later, these teachers have adjusted both their teaching styles and philosophies. The results from this study show that after more than 10 years in the classroom, these teachers now have their teaching style and philosophy in alignment. The teachers are student-centered in both philosophy and style.

    2017-09-01

    Social scientists need practical methods for harnessing large, publicly available datasets that inform the social context of aging. We describe our development of a semi-automated text coding method and use a content analysis of Alzheimer's disease (AD) and dementia portrayal on Twitter to demonstrate its use. The approach improves feasibility of examining large publicly available datasets. Machine learning techniques modeled stigmatization expressed in 31,150 AD-related tweets collected via Twitter's search API based on 9 AD-related keywords. Two researchers manually coded 311 random tweets on 6 dimensions. This input from 1% of the dataset was used to train a classifier against the tweet text and code the remaining 99% of the dataset. Our automated process identified that 21.13% of the AD-related tweets used AD-related keywords to perpetuate public stigma, which could impact stereotypes and negative expectations for individuals with the disease and increase "excess disability". This technique could be applied to questions in social gerontology related to how social media outlets reflect and shape attitudes bearing on other developmental outcomes. Recommendations for the collection and analysis of large Twitter datasets are discussed.

    To assess whether teaching female pelvic examinations using gynaecological teaching associates (GTAs); women who are trained to give instruction and feedback on gynaecological examination technique, improves the competence, confidence and communication skills of medical students compared to conventional teaching. Randomised controlled trial. Ten University of Birmingham (UoB) affiliated teaching hospitals in the UK. 492 final year medical students. GTA teaching of gynaecological examination compared with conventional pelvic manikin based teaching at the start of a five week clinical placement in obstetrics and gynaecology (O&G). Student's perception of their confidence was measured on a 10cm visual analogue scale (VAS). Domains of competence were measured by a senior clinical examiner using a standardised assessment tool which utilised 10cm VAS and by a GTA using a four point Likert scale. Assessors were blinded to the allocated teaching intervention. 407/492 (83%) students completed both the intervention and outcome assessment. Self-reported confidence was higher in students taught by GTAs compared with those taught on manikins (median score GTA 6.3; vs. conventional 5.8; p=0.03). Competence was also higher in those taught by GTAs when assessed by an examiner (median global score GTA 7.1 vs. conventional 6.0; pteaching of female pelvic examination at the start of undergraduate medical student O&G clinical placements improves their confidence and competence compared with conventional pelvic manikin based teaching.

    2016-11-22

    Learning to undertake intimate female and male examinations is an important part of medical student training but opportunities to participate in practical, supervised learning in a safe environment can be limited. A collaborative, integrated training programme to provide such learning was developed by two university teaching departments and a specialist sexual health service, utilising teaching associates trained for intimate examinations in a simulated clinical educational setting. The objective of this research was to determine changes in senior medical students' self- reported experience and confidence in performing male and female genital examinations, before and after participating in a new clinical teaching programme. A quasi-experimental mixed methods design, using pre and post programme questionnaires and focus groups, was used to assess the effectiveness of the programme. The students reported greatly improved skill, confidence and comfort levels for both male and female genital examination following the teaching programme. Skill, confidence and comfort regarding male examinations were rated particularly low on the pre-teaching programme self- assessment, but post-programme was rated at similar levels to the female examination. This integrated female-male teaching programme (utilising trained teaching associates as simulated patients in a supervised clinical teaching environment) was successful in increasing senior medical students' skills and levels of confidence in performing genital examinations. There were differences between female and male medical students in their learning. Suggestions for improvement included providing more detailed instruction to some clinical supervisors about their facilitation role in the session.

  18. Understanding Notional Machines through Traditional Teaching with Conceptual Contraposition and Program Memory Tracing

    2016-08-01

    Full Text Available A correct understanding about how computers run code is mandatory in order to effectively learn to program. Lectures have historically been used in programming courses to teach how computers execute code, and students are assessed through traditional evaluation methods, such as exams. Constructivism learning theory objects to students’ passiveness during lessons, and traditional quantitative methods for evaluating a complex cognitive process such as understanding. Constructivism proposes complimentary techniques, such as conceptual contraposition and colloquies. We enriched lectures of a “Programming II” (CS2 course combining conceptual contraposition with program memory tracing, then we evaluated students’ understanding of programming concepts through colloquies. Results revealed that these techniques applied to the lecture are insufficient to help students develop satisfactory mental models of the C++ notional machine, and colloquies behaved as the most comprehensive traditional evaluations conducted in the course.

    Students' evaluations of teaching staff can be considered high-stakes, as they are often used to determine promotion, reappointment, and merit pay to academics. Using Facets, the reliability and validity of one student rating questionnaire is analyzed. A total of 13,940 respondents of the Human Science Division of International Islamic University Malaysia were involved in the study. The analysis shows that the student rating questionnaire used was valid and reliable, and it allows identification of staff for the institution's prestigious teaching excellence awards, and those needing in-service training. It was found that there was no significant difference in terms of rank, age and gender of the staff. The study also shows that the majority of staff have problems keeping the class interested and getting students to participate in class activities. Faculty also hardly discussed common errors in assignments and tests.

    Client education and patient well-being should be primary goals and responsibilities for practicing avian veterinarians. Time is limited in the normal clinical appointment setting. However, this opportunity can still be used to introduce clients to the basics of training with positive reinforcement.

    2008-01-01

    Many VR technology based training systems use expert's motion data as the training aid, but would not provide any short-cut to teaching medical skills that do not depend on exact motions. Earlier we presented Annotated Simulation Records (ASRs), which can be used to encapsulate experts' insight on psychomotor skills. Annotations made to behavioural parameters in training simulators enable asynchronous teaching instead of just motion training in a proactive way to the learner. We evaluated ASRs for asynchronous teaching of Digital Rectal Examination (DRE) with 3 urologists and 8 medical students. The ASRs were found more effective than motion-based training with verbal feedback.

    2008-12-01

    Under the current nursing education system in Taiwan, a fair and objective evaluation of group health teaching competency has been lacking for a long time. Therefore, the purpose of this study was to establish a competency-based group health teaching performance examination model for baccalaureate graduates. Action research was the main research methodology used in this study. The research consisted of two phases. In the first phase, a development committee was established. Based on routine discussions, literature reviews and realistic cases, a draft examination model with quasi-clinical situation model content and procedure was developed. Examination Facility Preparations, Simulated Scenarios and Client Recruitments, Examination Result Evaluation (evaluated by teachers) and Learning Guidelines were also prepared. This draft was reviewed twice for expert opinion, a pilot test was done and both the draft and pilot testing were reviewed again before the draft was finalized. The second phase involved refining the examination model by actually practicing the completed draft examination model in a simulated group-teaching setting in order to examine the model's reliability and validity. Fifteen people were involved in this experiment: three nursing personnel each having at least two years' clinical and teaching experience; three nursing students who did not have actual clinical experience and had not taken the course of teaching principles; three senior teachers; and six virtual patients. The responses from the nursing personnel, nursing students, teachers, and virtual patients who participated in the testing were gathered and integrated to refine the model. The model has content, expert and discriminative validity. The reliability of the model was proven by the high consistency in administration and scoring of the model by clinical examiners. This examination model is not only applicable for the proof of students' credit point exemption, but also as an alternative

    2016-12-01

    Full Text Available The exposed selvedge layers in slabs cast by the continuous process should be free from surface defects, which in most cases appear in the form of cracks on the casting surface and run to its interior. In addition to the parameters of the casting process, the occurrence of such defects depends on the chemical composition of cast steel, on the segregation of surface active elements and formation of the precipitates of carbides, nitrides and other phases. Due to the frequent occurrence of defects in corners of the slabs, non-destructive testing was performed on the mechanically cleaned surfaces of slabs. The test material was low-carbon API(American Petroleum Institute API 5L standard steel micro alloyed with Nb and Ti designed for the production of pipes to handle gas, oil and other liquid and gaseous fuels. Despite the use of different methods of inspection, i.e. ultrasonic, magnetic particle and penetrant, cracks were not traced in the examined material. Then, from the corners of the examined slabs, specimens were cut out for metallographic examinations. The main purpose of these examinations was to disclose the presence of possible cracks and micro cracks on the surfaces transversal and longitudinal to the direction of casting. At the same time, studies were conducted to establish the number and morphology of non-metallic inclusions in selvedge layers of the slab corners and axis. Additionally, hardness of the slabs was measured. The conducted studies revealed only some minor differences in the slab hardness along its axis (130 ÷ 135 HB and in selvedge layers (120 ÷ 123 HB.

    2016-02-01

    Full Text Available Meelad Sayma, Hywel Rhys Williams Peninsula College of Medicine and Dentistry, Plymouth, UK Introduction: Teaching effective physical examination is a key component in the education of medical students. Preclinical medical students often have insufficient clinical knowledge to apply to physical examination recall, which may hinder their learning when taught through certain understanding-based models. This pilot project aimed to develop a method to teach physical examination to preclinical medical students using “core clinical cases”, overcoming the need for “rote” learning. Methods: This project was developed utilizing three cycles of planning, action, and reflection. Thematic analysis of feedback was used to improve this model, and ensure it met student expectations. Results and discussion: A model core clinical case developed in this project is described, with gout as the basis for a “foot and ankle” examination. Key limitations and difficulties encountered on implementation of this pilot are discussed for future users, including the difficulty encountered in “content overload”. Conclusion: This approach aims to teach junior medical students physical examination through understanding, using a simulated patient environment. Robust research is now required to demonstrate efficacy and repeatability in the physical examination of other systems. Keywords: physical examination, undergraduate, case-based approach

    [This paper is part of the Focused Collection on Preparing and Supporting University Physics Educators.] We present a newly validated and refined framework, TA-PIVOT (TA Practices In and Views Of Teaching), for examining how physics TAs talk about and how they engage in physics teaching. This work builds upon and extends prior efforts to characterize instructors' beliefs and practices by examining both domains in parallel. We present the comprehensive framework (developed from a study of 31 total TAs) and demonstrate its utility in analyzing both interviews and classroom video observations for a sample of eight TAs. We also discuss how this framework may be used to examine variation in beliefs and practices, track the development of beliefs over time, and inform TA preparation.

    2017-02-01

    This study examined the extent to which the instructional practices of science teachers in Barbados are congruent with best practices for teaching for scientific literacy. Additionally, through observation of practice, it sought to determine the teachers' demonstrated role in the classroom, their demonstration of learning through discourse, learning goals and the nature of classroom activities. Five hundred nineteen students from 12 of the 23 secondary schools on the island and 15 teachers across 8 schools participated in the study. Data were collected by means of a questionnaire, an observational schedule and field notes. It was found that while problem-solving and questioning were mainly used in the classroom, the use of experiments was among the least popular teaching strategies. Additionally, results showed that teachers' display of the knowledge of the characteristics of scientific literacy was unsatisfactory. Generally, the findings indicate a gap between teaching for scientific literacy as expressed in the literature and current instructional practices in secondary science classrooms in Barbados.

    Full Text Available Background: Ultrasonography is increasingly used for teaching physical examination in medical schools. This study seeks the opinions of educators as to which physical examinations would be most enhanced by the addition of ultrasonography. We also asked when ultrasound-aided physical examination teaching could have deleterious effects if used outside its intended scope. Methods: All of the educators from the University of Calgary Master Teacher Program were invited to complete a 22-item paper-based survey. Survey items were generated independently by two investigators, with input from an expert panel (N = 5. Results: Of the 36 educators, 27 (75% completed the survey. Examinations identified to be potentially most useful included: measuring the size of the abdominal aorta, identifying the presence/absence of ascites, identifying the presence/absence of pleural effusions, and measuring the size of the bladder. Examinations thought to be potentially most harmful included: identifying the presence/absence of intrauterine pregnancy, measuring the size of the abdominal aorta, and identifying the presence/absence of pericardial effusion. Conclusions: Examinations that are potentially the most useful may also be potentially the most harmful. When initiating an ultrasound curriculum for physical examinations, educators should weigh the risks and benefits of examinations chosen.

  19. Effectiveness of a 40-minute Ophthalmologic Examination Teaching Session on Medical Student Learning

    Directory of Open Access Journals (Sweden)

    Wirachin Hoonpongsimanont

    2015-10-01

    Full Text Available Introduction: Emergency physicians are among the few specialists besides ophthalmologists who commonly perform ophthalmologic examinations using the slit lamp and other instruments. However, most medical schools in the United States do not require an ophthalmology rotation upon completion. Teaching procedural skills to medical students can be challenging due to limited resources and instructor availability. Our study assesses the effectiveness of a 40-minute hands-on teaching session on ophthalmologic examination for medical students using only two instructors and low-cost equipment. Methods: We performed an interventional study using a convenience sample of subjects. Pre- and post-workshop questionnaires on students’ confidence in performing ophthalmologic examination were administered. We used a paired t-test and Wilcoxon rank test to analyze the data. Results: Of the 30 participants in the study, the mean age was 25 and the majority were first-year medical students. The students’ confidence in performing every portion of the ophthalmologic exam increased significantly after the teaching session. We found that the average confidence level before the teaching session were below 2 on a 1-5 Likert scale (1 being the least confident. Confidence levels in using the slit lamp had the highest improvement among the skills taught (2.17 95% CI [1.84-2.49]. Students reported the least improvement in their confidence in assessing extraocular movements (0.73, 95% CI [0.30-1.71] and examining pupillary function (0.73, 95% CI [0.42-1.04]. We observed the biggest difference in median confidence level in the use of the tonometer (4 with a p-value of <0.05. Conclusion: A 40-minute structured hands-on training session can significantly improve students’ confidence levels in ophthalmologic skills.

    Maldonado-Rivera, Jose Gabriel

    1998-12-01

    The factors affecting the teaching and learning of evolution were examined in the public schools of Puerto Rico. The study explored (1) the extent and nature of evolution education; (2) the role of teacher's attitudes, knowledge and beliefs in the teaching of evolution; (3) the nature and sources of student misconceptions; and (4) the extent to which conceptual change teaching can induce changes in these misconceptions. Questionnaires, interviews, and an experimental intervention were used to ascertain the factors affecting the teaching and learning of evolution. Among the study's major findings: (1) While evolution is present in the official curriculum, it is not treated as a central unifying theme. (2) In actual teaching evolution is completely neglected. (3) This neglect is due to several factors including: the religious beliefs of teachers; deficient pre-service training in particular poor training in history and philosophy of science, and deficient content and methods knowledge. (4) Students possess a wide variety of misconceptions about evolutionary theory. While some of these are ascribable to religion, many are related to other aspects of student affect, knowledge and cognition, including: (a) a misunderstanding of the nature of science; (b) methodological, epistemological and ontological commitments which difficultate comprehension; (c) the distorting influence of an anthropocentric, urban experience; (d) deficiencies in prior knowledge; and (e) an ahistoric worldview. (5) Conceptual change teaching was found to be more effective in transforming student views towards more scientific ones, than traditional didactic instruction. Conceptual change instruction: (a) increased the explanatory repertoire of students; (b) promoted greater changes towards more scientific conceptions; (c) increased student acceptance and understanding of evolutionary theory, and (d) induced more students to incorporate evolution in their explanations of biological phenomena. These

  2. Building a Digital Library from the Ground Up: an Examination of Emergent Information Resources in the Machine Learning Community

    Science.gov (United States)

    Cunningham, Sally Jo

    The current crop of digital libraries for the computing community are strongly grounded in the conventional library paradigm: they provide indexes to support searching of collections of research papers. As such, these digital libraries are relatively impoverished; the present computing digital libraries omit many of the documents and resources that are currently available to computing researchers, and offer few browsing structures. These computing digital libraries were built 'top down': the resources and collection contents are forced to fit an existing digital library architecture. A 'bottom up' approach to digital library development would begin with an investigation of a community's information needs and available documents, and then design a library to organize those documents in such a way as to fulfill the community's needs. The 'home grown', informal information resources developed by and for the machine learning community are examined as a case study, to determine the types of information and document organizations 'native' to this group of researchers. The insights gained in this type of case study can be used to inform construction of a digital library tailored to this community.

    Nurse educators might be unknowingly excluding learners secondary to teaching practices. Universal design for instruction (UDI) prepares and delivers accessible content and learning environments for diverse learners; however, it is not well known in nursing education. The aim of the study was to examine the psychometric properties of the Inclusive Teaching Strategies in Nursing Education (ITSinNE) 55-item instrument. Confirmatory factor analysis was performed on a sample of 311 educators in prelicensure programs. The ITSinNE scales had good to adequate estimates of reliability. The exogenous model fit the sample and model-implied covariance matrix; however, the endogenous model was not a good fit. Further instrument development is required. Measuring factors influencing nurse educators' willingness to adopt UDI will enable intervention research to enhance professional development fostering content and environmental access for all learners.

    Seung, Eulsun

    The purpose of this study was to investigate how graduate physics teaching assistants (TAs) develop professional knowledge for teaching a new undergraduate introductory physics curriculum, Matter and Interactions (M&I ). M&I has recently been adopted as a novel introductory physics course that focuses on the application of a small number of fundamental physical principles on the atomic and molecular nature of matter. In this study, I examined the process of five TAs' development of knowledge for implementing the M&I course---from the time they engaged in an M&I content and methods workshop through their first semester as TAs for the course. Through a qualitative, multiple case study research design, data was collected from multiple sources: non-participant observations, digitally recorded video, semi-structured interviews, TAs' written reflections, and field notes. The data were analyzed using the constant comparative method. The TAs' knowledge for teaching M&I was identified in three domains: pedagogical content knowledge, pedagogical knowledge, and subject matter knowledge. First, the three components of TAs' pedagogical content knowledge were identified: knowledge of the goals of M&I, knowledge of instructional strategies, and knowledge of students' learning. Second, pedagogical knowledge that the TAs demonstrated during the study fell predominantly into the category of classroom management and organization. The knowledge of classroom management and organization was categorized into two components: time management skills and group composition. Last, the TAs' subject matter knowledge that they developed through their M&I teaching experience was described in terms of the conceptual structure of the M&I curriculum, the new approach of the M&I curriculum, and specific topic knowledge. The TAs' knowledge for teaching developed from propositional knowledge to personal practical knowledge, and the process of knowledge development consisted of three phases: accepting

  6. Teaching musculoskeletal examination skills to UK medical students: a comparative survey of Rheumatology and Orthopaedic education practice.

    2014-03-28

    Specialists in Rheumatology and Orthopaedics are frequently involved in undergraduate teaching of musculoskeletal (MSK) examination skills. Students often report that specialty-led teaching is inconsistent, confusing and bears little resemblance to the curricula. The Gait, Arms, Legs and Spine (GALS) is a MSK screening tool that provides a standardised approach to examination despite it being fraught with disapproval and low uptake. Recent studies would appear to support innovative instructional methods of engaging learners such as patient educators and interactive small group teaching. This comparative cross-sectional survey evaluates the current state of undergraduate teaching in Rheumatology and Orthopaedics, including preferred teaching methods, attitudes towards GALS, and barriers to effective teaching. An electronic questionnaire was sent to specialist trainees and Consultants in the East and West Midlands region, representing 5 UK medical schools. Descriptive statistical data analysis was performed. There were 76 respondents representing 5 medical schools. There was a request for newer teaching methodologies to be used: multi-media computer-assisted learning (35.5%), audio-visual aids (31.6%), role-playing (19.7%), and social media (3.9%). It is evident that GALS is under-utilised with 50% of clinicians not using GALS in their teaching. There is a genuine desire for clinical educators to improve their teaching ability, collaborate more with curriculum planners, and feel valued by institutions. There remains a call for implementing a standardised approach to MSK clinical teaching to supersede GALS.

  13. Teaching Science for Social Justice: An Examination of Elementary Preservice Teachers' Beliefs

    Science.gov (United States)

    Eslinger, James C.

    This qualitative study examines the beliefs and belief changes of eleven elementary preservice teachers about teaching science for social justice. Using constructivist grounded theory, it forwards a new theory of belief change about teaching science for social justice. The theory posits that three teaching and learning conditions may facilitate belief change: preservice teachers need to recognize (1) the relationship between science and society; (2) the relationship between individuals and society; and (3) the importance of taking action on socioscientific issues. This research responds to calls by critical scholars of teacher education who contend that beliefs in relation to equity, diversity, and multiculturalism need to be explored. They have found that many preservice teachers hold beliefs that are antithetical to social justice tenets. Since beliefs are generally considered to be precursors to actions, identifying and promoting change in beliefs are important to teaching science for social justice. Such a move may lead to the advancement of curricular and pedagogical efforts to promote the academic participation and success in elementary science of Aboriginal and racialized minority students. The study was undertaken in a year-long science methods course taught by the researcher. It was centered on the preservice teachers -- their beliefs, their belief changes, and the course pedagogies that they identified as crucial to their changes. However, the course was based on the researcher-instructor's review of the scholarly literature on science education, teacher education, and social justice. It utilized a critical -- cultural theoretical framework, and was aligned to the three dimensions of critical nature of science, critical knowledge and pedagogy, and sociopolitical action. Findings indicate that, at the beginning of the year, preservice teachers held two types of beliefs (liberal and critical) and, by the end of the course, they experienced three kinds of

    Full Text Available The FAMULATUR PLUS is an innovative approach to teaching physical examination skills. The concept is aimed at medical students during the clinical part of their studies and includes a clinical traineeship (English for “Famulatur” extended to include various courses (“PLUS”. The courses are divided into clinical examination courses and problembased-learning (PBL seminars. The concept’s special feature is the full integration of these courses into a 30-day hospital traineeship. The aim is to facilitate the transfer of knowledge from the courses into daily practice. Each week of the FAMULATUR PLUS is structured in line with the courses and focuses on a particular part of the body (e.g., abdomen. A physical examination course under the supervision of a physician is offered at the beginning of the week. Here, medical students learn the relevant examination techniques by practicing on each other (partner exercises. Subsequently, the techniques taught are applied independently during everyday work on the ward, corrected by the supervisor, if necessary, and thereby reinforced. The final POL seminar takes place towards the end of the week. Possible differential diagnoses are developed based on a clinical case study. The goal is to check these by taking a fictitious medical history and performing a physical examination, as well as to make a preliminary diagnosis. Finally, during the PBL seminar, medical students will be shown how physical examination techniques can be efficiently applied in the diagnosis of common cardinal symptoms (e.g., abdominal pain. The initial implementation of the FAMULATUR PLUS proved the practical feasibility of the concept. In addition, the accompanying evaluation showed that the participants of the pilot project improved with regard to their practical physical examination skills.

    2009-01-01

    A biologically inspired spiking neural network model, called pulse-coupled neural networks (PCNN), has been applied in an automatic inspection machine to detect visible foreign particles intermingled in glucose or sodium chloride injection liquids. Proper mechanisms and improved spin/stop techniques are proposed to avoid the appearance of air bubbles, which increases the algorithms' complexity. Modified PCNN is adopted to segment the difference images, judging the existence of foreign particles according to the continuity and smoothness properties of their moving traces. Preliminarily experimental results indicate that the inspection machine can detect the visible foreign particles effectively and the detection speed, accuracy and correct detection rate also satisfying the needs of medicine preparation.

    Rowe, Robert

    2002-05-01

    The training of musicians begins by teaching basic musical concepts, a collection of knowledge commonly known as musicianship. Computer programs designed to implement musical skills (e.g., to make sense of what they hear, perform music expressively, or compose convincing pieces) can similarly benefit from access to a fundamental level of musicianship. Recent research in music cognition, artificial intelligence, and music theory has produced a repertoire of techniques that can make the behavior of computer programs more musical. Many of these were presented in a recently published book/CD-ROM entitled Machine Musicianship. For use in interactive music systems, we are interested in those which are fast enough to run in real time and that need only make reference to the material as it appears in sequence. This talk will review several applications that are able to identify the tonal center of musical material during performance. Beyond this specific task, the design of real-time algorithmic listening through the concurrent operation of several connected analyzers is examined. The presentation includes discussion of a library of C++ objects that can be combined to perform interactive listening and a demonstration of their capability.

  5. An Examination of Pre-service Classroom Teaching Programs in terms of Gifted Education in Turkey

    Directory of Open Access Journals (Sweden)

    Eda DEMİRHAN

    2016-12-01

    Full Text Available It has been recently given importance that programs are prepared in consideration of individual differences of children with the need for special education. Even if it is especially thought that children with the need for special education are just physically or mentally disabled, one should recognize children whom we can actually call 'gifted' for them to be able to adapt to the classroom environment. Provided that the first-, second- and third-grade students are nominated by the classroom teachers as of the academic year of 2016-2017, they will be able to receive education at Science-Art Centers. Therefore, classroom teachers undertake an important task for identifying gifted children. Can teachers having such a great responsibility be trained to have that competence? The main purpose of this study is to investigate to what extent the subject 'gifted students' is included in the teaching plan during the eight-term education of pre-service classroom teachers. For this purpose, the websites of 193 universities registered to the Council of Higher Education were identified to examine 70 universities with a classroom teaching program. According to the findings, there is a course called 'special education' that handles the topics related to the gifted in 68 of those 70 universities, and in the rest, there is no course titled either 'special education' or 'gifted'. When the special education course is investigated, it is seen that objectives concerning the gifted take the last places and the contents addressing the gifted takes the third place. According to the learning acquisitions of the special education course, 'knowing about the characteristics of gifted children and educational applications for them' comes across as one of the least addressed topics.

    Given their ability to process highly dimensional datasets with hundreds of variables, machine learning algorithms may offer one solution to the vexing challenge of predicting postoperative pain. Here, we report on the application of machine learning algorithms to predict postoperative pain outcomes in a retrospective cohort of 8,071 surgical patients using 796 clinical variables. Five algorithms were compared in terms of their ability to forecast moderate to severe postoperative pain: Least Absolute Shrinkage and Selection Operator (LASSO), gradient-boosted decision tree, support vector machine, neural network, and k-nearest neighbor (k-NN), with logistic regression included for baseline comparison. In forecasting moderate to severe postoperative pain for postoperative day (POD) 1, the LASSO algorithm, using all 796 variables, had the highest accuracy with an area under the receiver-operating curve (ROC) of 0.704. Next, the gradient-boosted decision tree had an ROC of 0.665 and the k-NN algorithm had an ROC of 0.643. For POD 3, the LASSO algorithm, using all variables, again had the highest accuracy, with an ROC of 0.727. Logistic regression had a lower ROC of 0.5 for predicting pain outcomes on POD 1 and 3. Machine learning algorithms, when combined with complex and heterogeneous data from electronic medical record systems, can forecast acute postoperative pain outcomes with accuracies similar to methods that rely only on variables specifically collected for pain outcome prediction.

    Melcher, Peter; Zajonz, Dirk; Roth, Andreas; Heyde, Christoph-E.; Ghanem, Mohamed

    2016-01-01

    Background: The OSCE (objective structured clinical examination) is composed of oral and practical examination in order to examine students’ abilities to imply clinical examination techniques and to interact with patients. The examiners for this procedure can be either lecturers or peers. The aim of this work is to evaluate the peer-assisted teaching student tutors as examiners in an orthopedic surgery OSCE station. Methods: We analyzed the OSCE data from 2013 to 2015. During this period over 300 medical students were examined each year. An evaluation was conducted at an orthopedic station and examined by peer students to assess the advantages and disadvantages of peer-assisted teaching student tutors as examiners. Results: We have noticed that student peers are more flexible regarding their schedule and they have been well trained for OSCE. Concerning the economic aspects, student peers are clearly of major economic advantage. Disadvantages were not reported in our study probably because peers were well trained and the checklists are monitored regularly. Conclusion: Student peers in OSCE are of major advantage due to their flexible time schedule and relatively low costs. They must be well trained and the checklists are to be monitored regularly. Our study shows that peer tutor examiners conducted the examination as competent as lecture examiners. However, legal restrictions on the employment of students should be considered. PMID:27500078

  1. Teaching of evolution in public schools: A cross-cultural examination

    Science.gov (United States)

    Stewart, Joshua M.

    The current study sought to examine how the cultural settings of Colorado, United States, and Baden-Wurttemberg, Germany, influenced perspectives, understandings, and acceptance of college students who want to become teachers (i.e., prospective teachers) in regard to the theory of evolution, creationism, and intelligent design with both quantitative and qualitative components. The quantitative sample for the study consisted of 221 German prospective teachers from Baden-Wurttemberg and 231 United States prospective teachers from Colorado. The quantitative component consisted of a 42-item survey with both Likert and true/false items to examine how (1) country of origin, (2) religious participation, and (3) educational background influence students' views and understandings of the theory of evolution and alternative conceptions. Additionally, in a Likert 6-item motivated reasoning task (a theoretical construct), prospective teachers were asked to read and critique arguments supporting and opposing the theory of evolution; differences in how students critiqued arguments were hypothesized to demonstrate biases. For a separate sample from the same locations (8 German and 11 United States students), a qualitative component examined prospective teachers' positions on teaching the theory of evolution in public schools. Prospective teachers were asked to provide support for their position, anticipate opposing arguments, and implications that both positions would have for students. Lastly, prospective teachers were also asked to explain and define the theory of evolution. The current study aided in examining how teachers' perspectives, understandings, and acceptance impacted what was taught in the science classroom. The researcher found that country of origin, religious behavior, and educational background predicted prospective teachers' responses to numerous criterion variables used in the current study. Further, qualitative results expressed major differences between

  2. Machine self-teaching methods for parameter optimization. Final report, October 1984-August 1986

    Energy Technology Data Exchange (ETDEWEB)

    Dillard, R.A.

    1986-12-01

    The problem of determining near-optimum parameter-control logic is addressed for cases where a sensor or communication system is highly flexible and the logic cannot be determined analytically. A system that supports human-like learning of optimum parameters is outlined. The major subsystems are (1) a simulation system (described for a radar example), (2) a performance monitoring system, (3) the learning system, and (4) the initial knowledge used by all subsystems. The initial knowledge is expressed modularly as specifications (e.g., radar constraints, performance measures, and target characteristics), relationships (among parameters, intermediate measures, and component performance measures), and formulas. The intent of the learning system is to relieve the human from the very tedious trial-and-error process of examining performance, selecting and applying curve-fitting methods, and selecting the next trial set of parameters. A learning system to design a simple radar meeting specific performance constraints is described in detail, for experimental purposes, in generic object-based code.

    2012-01-01

    Full Text Available Researches and educators’ recognition of positive and negative effects of tests on teaching and learning activities goes back at least four decades. Although educators frequently claim that they do not want to teach to a test, the reality is that every educator wants his/her students to be successful. Decision makers, teachers, and students equate this success in large part with high test scores, resulting in classroom instruction that is reflective of test practices and/or expectations. The effect that testing has on teaching and instruction is a phenomenon referred to as washback. However, this phenomenon has been examined empirically by only a few studies in the field of language testing. This qualitative study aimed to (i investigate the existence and nature of the washback effect, and (ii examine the role of EEOU context in promoting beneficial washback. The findings confirmed the existence of washback phenomenon in general and negative washback effects of EEOU context on language teaching and learning in particular.

  1. A collaborative integrated stem teaching: Examination of a science and math teacher collaboration on an integrated stem unit

    Science.gov (United States)

    Ayres, Drew C.

    The integration of science, technology, engineering and mathematics curriculum in middle school science and math classrooms is a reform effort currently taking place. The teachers are being encouraged to teach integrated content through national and state standards. The teachers have not been trained to do this form of teaching, which has led to feelings of discomfort or incompetence to fulfill those standards. This has led to a need for professional developments to train these teachers. Those developing the professional developments are seeking to identify ways to encourage teachers to continue to implement integrated units. The purpose of this study was to examine the impact of a collaborative teaching relationship between a math and science teacher following a professional development. The teachers used a common integrated STEM unit to teach math and science standards by using engineering design as the integrator. The teachers provided lesson plans, were video recorded during implementation, interviewed pre and post-implementation, and made daily journal entries. These data were analyzed to document the collaboration and identify impacts of the collaboration.

    Video modeling has been shown to be effective in teaching a number of skills to learners diagnosed with autism spectrum disorders (ASD). In this study, we taught two young men diagnosed with ASD three different activities of daily living skills (ADLS) using point-of-view video modeling. Results indicated that both participants met criterion for all ADLS. Participants did not maintain mastery criterion at a 1-month follow-up, but did score above baseline at maintenance with and without video modeling. • Point-of-view video models may be an effective intervention to teach daily living skills. • Video modeling with handheld portable devices (Apple iPod or iPad) can be just as effective as video modeling with stationary viewing devices (television or computer). • The use of handheld portable devices (Apple iPod and iPad) makes video modeling accessible and possible in a wide variety of environments.

  3. Examining the Latest Threat to the Teaching of Evolution in our Classrooms

    Science.gov (United States)

    Scotchmoor, J.

    2001-05-01

    Evolution is not just a theory; it is fundamental to our understanding of life and its history. Evolution is good science, not a belief system. It requires conclusive evidence that can be subjected to the tests of observation and objective reasoning. As defined within the National Science Education Standards, scientific inquiry is a set of interrelated processes by which scientists and students pose questions about the natural world. This definition must guide what is taught in science classrooms. In February, 2001 the Kansas Board of Education reversed a controversial 1999 decision and approved a new set of science standards. This action included a definition of science that focuses on the natural world and returned the teaching of evolution to the classroom, including the origin of the universe and the age of the earth. The vote was 7-3 in favor of the new standards and against an amendment put forth to accept revisions suggested by the local Intelligent Design Network (IDN). Following this decision, John Calvert, a managing director of the IDN, said that he was disappointed but not surprised, and that his group plans to take its case to school boards across the country. This threat should not be taken lightly. School boards ultimately influence or decide what is taught in classrooms. The events in Kansas were instrumental in waking up a lethargic educational and scientific community, but we cannot afford to rest easy now that evolution has been returned to Kansas science standards. The presence of evolution in science standards does not guarantee the teaching of evolution in science classrooms. Nor does it guarantee that teachers are prepared for the new anti-evolution strategies employed by the IDN. These tactics include claims of censorship and demands for the presentation of alternative scientific theories. They also include challenges based upon religion and philosophy, not science, and they place the teacher in the role of debater instead of educator. In

    2014-08-01

    This article, the second in a two-part series, details a correlational study that examined the effects of four variables (graduate degrees in nursing education, professional development training in adult learning theory, nursing professional development [NPD] certification, and NPD specialist experience) on the use of adult learning theory to guide curriculum development. Using the Principles of Adult Learning Scale, 114 NPD specialists tested the hypothesis that NPD specialists with graduate degrees in nursing education, professional development training in adult learning theory, NPD certification, and NPD experience would use higher levels of adult learning theory in their teaching practices to guide curriculum development than those without these attributes. This hypothesis was rejected as regression analysis revealed only one statistically significant predictor variable, NPD certification, influenced the use of adult learning theory. In addition, analysis revealed NPD specialists tended to support a teacher-centered rather than a learner-centered teaching style, indicating NPD educators are not using adult learning theory to guide teaching practices and curriculum development.

  5. An examination of the relationship among science teaching actions, beliefs, and knowledge of the nature of science

    Science.gov (United States)

    Chun, Sajin

    Scholars in science education advocate curriculum and instruction practices that reflect an understanding of the nature of science. This aspect of school science is an important component of scientific literacy, a primary goal of science education. Considering teaching as a thoughtful profession, there has been a growing research interest on the issue of the consistency between teacher beliefs and actions. Yet, the self-evident assumption that teachers' beliefs about the nature of science will impact on their classroom teaching actions has not been justified. The purpose of this study was to examine the relationship between science teaching actions and beliefs about the nature of science. Defining teacher beliefs as a broad construct, the researcher tried to examine not only teacher's cognitive understanding about the nature of science but also teachers' affect as well as actions with regard to the nature of science. Guiding research questions were as follows: (a) what are the teachers' beliefs about the nature of science; (b) how do the teachers, pedagogical actions reflect their beliefs about the nature of science; and (c) what are the other referent beliefs that mediate the teachers, pedagogical actions within a local school culture. The methodology of this study was an interpretive, qualitative approach that included multiple sources of data, interviews, classroom observations, and instructional materials. Six science teachers from a secondary school located in a rural area of the southeastern US were chosen by convenience. The cross-case study and the grounded theory study designs were adopted as the data analysis process. The constant comparative analysis method was used to generate the emerging themes for this study. This study revealed a gap between these teachers' personal beliefs of the nature of science and the concepts of the nature of science suggested by many researchers. These teachers' personal beliefs about the nature of science have been

    This study was conducted to evaluate the effectiveness of a peer education model in teaching breast self-examination to a late adolescence female student group attending the second class of Buca Educational Faculty of Dokuz Eylül University (DEU). A total of 15 volunteer students were given the breast self-examination training programme by a researcher and thereby became qualified as peer educators. Each then reached 10 peers and conveyed information on the Breast-Self Examination Programme. The identification forms of the students were filled out by the researcher. Evaluation forms I and II developed by Maurer (1997) for regular BSE practice and skills were used and evaluated with 100 points. The "paired t-test", "Student's t-test", "McNemar test", and "Pearson correlation test" were employed to for statistical assessment. According to the evaluation results; while the students's average point of knowledge on BSE was 43.0 +/- 11.7 before training, it became 88.9 +/- 8.15 after a week, and 86.9 +/- 9.69 after four weeks. It was obvious that there was a meaningful difference between those knowledge rates (pstudents was 2.6% before training it increased to 66% (pstudents BSE practice skills became 91.5 +/- 7.25 at four weeks after the training with a significant increase as well (r=0,70). Therefore we conclude that the peer education model is an effective method for teaching breast self examination to students.

    Full Text Available The purpose of this study was to investigate attitudes of pre-service teachers toward the teaching profession with respect to their gender, grade level, whether participants regularly participate in physical activities, and whether pre-service students have a teacher-parent in their family. Research was conducted on 469 pre-service physical education teachers (Mage=21.35, SDage= 2.49, 188 female (Mage=20.89, SDage= 2.30 and 281 male (Mage=21.66, SDage= 2.57 students from five different universities in Turkey. In this study the “Attitude Scale for the Profession of Physical Education Teaching” was used. It has two factors: “concern for profession” (CP and “affection for profession” (AP. Independent sample t-test results indicated that there were no significant differences with respect to gender or having a teacher-parent in both factors and total attitude points (p> 0.05. Pre-service physical education teachers who participate in physical activity had significantly higher points in AP and the total scale in comparison to those who do not participate in physical activity (p< 0.05. ANOVA results indicated that based on grade level there were significant differences in CP and total attitude (p< 0.05. Students’ concern about employment may be associated with differences in attitude scores between grade levels. The positive effect of physical activity participation and their professional teaching education on stress resilience might also be an important factor for increasing positive attitudes toward the teaching profession.

    Until recently we were the sole designers, alone in the driving seat making all the decisions. But, we have created a world of complexity way beyond human ability to understand, control, and govern. Machines now do more trades than humans on stock markets, they control our power, water, gas...... and food supplies, manage our elevators, microclimates, automobiles and transport systems, and manufacture almost everything. It should come as no surprise that machines are now designing machines. The chips that power our computers and mobile phones, the robots and commercial processing plants on which we...... depend, all are now largely designed by machines. So what of us - will be totally usurped, or are we looking at a new symbiosis with human and artificial intelligences combined to realise the best outcomes possible.

    The aim of this retrospective cohort study was to gain an insight into frequencies by which a range of medical imaging (MI) examinations were performed on paediatric patients at the main acute general teaching hospital in Malta between 2008 and 2014. Frequency data of MI examinations performed on paediatric patients were retrospectively collected from relevant information systems. All data was coded accordingly to facilitate data analysis. A total of 95,805 MI examinations were performed on 39,707 unique paediatric patients (<18 years) between 2008 and 2014. Overall, the total number of paediatric MI examinations performed decreased over time, with use varying depending on modality type and paediatric age. Coincidentally the use of ultrasound and MRI increased year after year. Some paediatric patients underwent at least three MI examinations involving the same anatomical region being scanned, and which may collectively contribute to effective doses exceeding 10 mSv. Knowledge of how MI examinations are used within the paediatric population can help practices evaluate and address any trends highlighted for particular examinations or age category of paediatric patients. Furthermore, awareness of current trends of MI in children can be helpful for the planning of future paediatric radiology departments. (orig.)

  18. A narrative inquiry into teaching physics as inquiry: An examination of in-service exemplars

    Science.gov (United States)

    Evans, Paige K.

    Studies show that teachers who have experienced inquiry are more likely to practice the inquiry method in their own classrooms (McDermott, 2007; Olson, 1995; Pereira, 2005; Windschitl, 2002). This study explores changes in science teachers' personal practical knowledge (Clandinin, 1986) after participating in a graduate level physics inquiry course and subsequent professional development throughout the school year. In addition, teacher participants were studied to determine the roadblocks they encountered when altering curriculum mandates in ways that would enable them to work with the inquiry method. The results of this course and subsequent professional development sessions were analyzed for the benefits of using the inquiry method to teacher learning and to ascertain whether the teacher participants would be more apt to employ the inquiry method in their own classrooms. Moreover, the results of this study were analyzed to inform my personal practice as a leader preparing undergraduate science teachers in the teachHOUSTON program as well as in my continuing work with in-service teachers. An inquiry course may be added to the teachHOUSTON course sequence, based on the discoveries unearthed by this thesis study. This research study is conducted as a narrative inquiry (Clandinin & Connelly, 1992, 2000; Craig, 2011; Polkinghorne, 1995) where story works as both a research method and a form of representation (Connelly & Clandinin, 1990). Narrative inquiry is strongly influenced by John Dewey (1938) who believed that one must rely on past experiences and knowledge to solve current and future problems and that life experience is in fact education. This study inquires into the narratives of two teachers who are teaching secondary science in public schools. These stories illuminate the teachers' lived experiences as they co-constructed curriculum with their students. The images of teacher as a curriculum maker vs. teacher as a curriculum implementer (Craig & Ross, 2008

    Full Text Available The paper presents a laboratory setup based on a SIMOVERT MASTER- DRIVES MC Inverter from SIEMENS used for open and closed loop speed control of an induction machine. The platform allows four quadrant operation of the machine using both the classical V/Hz scalar principle and field oriented vector control principle. The rectifier unit consists of a classical three phase diode bridge and two high voltage capacitors in order to obtain a voltage source behavior of the converter. In order to obtain the four quadrant operation of the drive, several methods are investigated out of which one is proposed and implemented. The theoretical aspects of V/Hz scalar principle and field oriented vector control principle are better explained using the proposed experimental platform.

    To date, studies of biological risk factors have revealed inconsistent relationships with subsequent post-traumatic stress disorder (PTSD). The inconsistent signal may reflect the use of data analytic tools that are ill equipped for modeling the complex interactions between biological and environmental factors that underlay post-traumatic psychopathology. Further, using symptom-based diagnostic status as the group outcome overlooks the inherent heterogeneity of PTSD, potentially contributing to failures to replicate. To examine the potential yield of novel analytic tools, we reanalyzed data from a large longitudinal study of individuals identified following trauma in the general emergency room (ER) that failed to find a linear association between cortisol response to traumatic events and subsequent PTSD. First, latent growth mixture modeling empirically identified trajectories of post-traumatic symptoms, which then were used as the study outcome. Next, support vector machines with feature selection identified sets of features with stable predictive accuracy and built robust classifiers of trajectory membership (area under the receiver operator characteristic curve (AUC)=0.82 (95% confidence interval (CI)=0.80–0.85)) that combined clinical, neuroendocrine, psychophysiological and demographic information. Finally, graph induction algorithms revealed a unique path from childhood trauma via lower cortisol during ER admission, to non-remitting PTSD. Traditional general linear modeling methods then confirmed the newly revealed association, thereby delineating a specific target population for early endocrine interventions. Advanced computational approaches offer innovative ways for uncovering clinically significant, non-shared biological signals in heterogeneous samples. PMID:28323285

    Analysis of Synchronous Machines, Second Edition is a thoroughly modern treatment of an old subject. Courses generally teach about synchronous machines by introducing the steady-state per phase equivalent circuit without a clear, thorough presentation of the source of this circuit representation, which is a crucial aspect. Taking a different approach, this book provides a deeper understanding of complex electromechanical drives. Focusing on the terminal rather than on the internal characteristics of machines, the book begins with the general concept of winding functions, describing the placeme

  5. Learning to Teach as Situated Learning: An Examination of Student Teachers as Legitimate Peripheral Participants in Cooperating Teachers' Classrooms

    Science.gov (United States)

    McDonald, Eric J.

    Learning to teach science well is a complex endeavor and student teaching provides a time for emerging teachers to learn how to reason in this uncertain landscape. Many pre-service teachers have rated student teaching as a very important part of their teacher education program (Koerner, Rust, & Baumgartner, 2002; Levine, 2006) and there is little doubt that this aspect of teacher preparation has a great impact (Wilson, Floden, Ferrinin-Mundy, 2001). It is surprising, therefore, that the interaction between the cooperating teacher and student teacher represents a gap in the literature (Cochran-Smith & Zeichner, 2005). In fact, little effort has been made in science education "to understand the contributions of cooperating teachers and teacher educators" (p. 322). Research is needed into not only how teacher preparation programs can help pre-service teachers make this transition from student teacher to effective teacher but also how the expertise of the cooperating teacher can be a better articulated part of the development of the student teacher. This instrumental case study examines the nature and substance of the cooperating teacher/student teacher conversations and the changes in those conversations over time. Using the theoretical framework of situated learning (Lave & Wenger, 1991; Lave, 1996) the movement of the student teacher from their position on the periphery of practice toward a more central role is examined. Three cooperating teacher/student teacher pairs provided insight into this important time with case data coming from pre and post interviews, baseline surveys, weekly update surveys, and recorded conversations from the pair during their time together. Four major themes emerged from the cases and from cross case comparisons with implications for student teachers regarding how they react to greater responsibility, cooperating teachers regarding how they give access to the community of practice, and the teacher preparation community regarding the role

    2013-01-01

    Full Text Available Background: Medical colleges in India conventionally follow a curriculum overfed with large volume of information expecting students will imbibe such curriculum unquestionably overlooking what and how they progress. There have been many attempts to improve the learning process of medical students, neglecting the process which students adopt towards such learning and prepare for their exams aiming better performance. Objective: To explore qualitatively the way medical undergraduates prepare for their university examination. Methods: Present qualitative research was undertaken among medical interns during Nov-2011 to March-2012. FGDs were conducted by trained moderator using semi-structured guidelines and note taker recorded each FGD. Content analysis of FGDs was primarily oriented towards behaviour of medical undergraduates during preparatory phase before their university examinations like study pattern, study material, eating behaviour, level of stress, addiction etc. Qualitative content analysis of textual level of data was undertaken using Atlas.ti.5.0 software package. Results: Students are serious about studies just before examinations and refer to notes prepared by seniors, small books with important topics, and self-made notes. Girls depend predominantly on self-made notes. Students primarily focus on important topics in each subject. Time-in-hand decides what they study and try to remember before exams. They become casual about their diet, clothing and self-care. Stress, fear and high academic expectation often drive them towards addictive substances. They often suffer from loneliness and seek empathy from opposite sex batch mates, seniors, teachers and family members and start believing in their fortune and examiners' will rather than actual preparation. Conclusion: Students' psychology and culture should be addressed in harmony with curriculum reform for better learning by medical undergraduates.

    2014-09-01

    Full Text Available Introduction: Education of children with special needs is an important field of study. Children with special needs deserve to be educated like any other human being. Over the years, several provisions have been made and laws have been passed to ensure education of children with special needs. A visually impaired child’s needs and goals for learning are not different from that of his sighted peers. Only the means of achieving those goals are different. Objective: The purpose of this study was to compare the prevalent method of teaching and the system of examination for students with Visual Impairment studying in the special schools for the blind in India and Japan. Methodology: The study was delimited to i blind students only and ii the special schools for the blind in Kolkata and Tokyo. Purposive sampling technique was used to select 50 teachers (25 each from the special schools for the blind in Kolkata and Tokyo. The researcher interviewed the teachers. Semi–structured information schedules were used to collect data and the data were analyzed only qualitatively. Findings: The method of teaching the blind students was similar in both Kolkata and Tokyo. Differences were observed mainly in the type of teaching equipments used. Regarding the system of examination, differences were observed within the special schools in Kolkata. In Tokyo, however, all the special schools followed a uniform system. The study revealed that in Kolkata a strict pass/fail criterion existed. In Tokyo, on the other hand, there was no strict pass/fail criterion. Conclusion: This study is important because not many comparative studies have been done between India and Japan. Most of the comparative research work is either between Japan and the U.S.A or between Japan and the U.K. This study was conducted mainly to find out the differences between a Developing and a Developed nation. Being a developed country, it is always assumed that there will be a lot to learn from

    In undergraduate medical education, the training of post-mortem external examination on dead bodies might evoke strong emotional reactions in medical students that could counteract the intended learning goals. We evaluated student perception of a forensic medicine course, their perceived learning outcome (via self-assessment) and possible tutor-dependent influences on the overall evaluation of the course by a questionnaire-based survey among 150 medical students in Hamburg, Germany. The majority of students identified post-mortem external examination as an important learning objective in undergraduate medical education and did not feel that the dignity of the deceased was offended by the course procedures. After the course, more than 70% of the students felt able to perform an external examination and to fill in a death certificate. Respectful behavior of course tutors towards the deceased entailed better overall course ratings by students (pformal curriculum) as well as tutor behavior (informal curriculum) in undergraduate education in forensic medicine. Furthermore, we suggest embedding teaching in forensic medicine in longitudinal curricula on death and dying and on the health consequences of interpersonal violence.

    2006-04-01

    The efficiency of engineering applied to civilian projects sometimes threatens to run away with the social agenda, but in military applications, engineering often adds a devastating sleekness to the inevitable destruction of life. The relative crudeness of terrorism (e.g., 9/11) leaves a stark after-image, which belies the comparative insignificance of random (as opposed to orchestrated) belligerence. Just as engineering dwarfs the bricolage of vernacular design 'moving us past the appreciation of brush-strokes, so to speak' the scale of engineered destruction makes it difficult to focus on the charred remains of individual lives. Engineers need to guard against the inappropriate military subsumption of their effort. Fortunately, the ethics of warfare has been an ongoing topic of discussion for millennia. This paper will examine the university core class I've developed (The Moral Dimensions of Technology) to meet accreditation requirements in engineering ethics, and the discussion with engineering and non-engineering students focused by the life of electrical engineer Vannevar Bush, with selected readings in moral philosophy from the Dao de Jing, Lao Tze, Cicero, Aurelius Augustinus, Kant, Annette Baier, Peter Singer, Elizabeth Anscombe, Philippa Foot, and Judith Thomson.

    2003-12-01

    Science education reform has skyrocketed over the last decade thanks in large part to the technology of the Internet, opening up dynamic new online communities of learners. It has allowed educators worldwide to share thoughts about Earth system science and reexamine the way science is taught. The Earth System Science Education Alliance (ESSEA) is one positive offshoot of this reform effort. This developing partnership among universities, colleges, and science education organizations is led by the Institute for Global Environmental Strategies and the Center for Educational TechnologiesTM at Wheeling Jesuit University. ESSEA's mission is to improve Earth system science education. ESSEA has developed three Earth system science courses for K-12 teachers. These online courses guide teachers into collaborative, student-centered science education experiences. Not only do these courses support teachers' professional development, they also help teachers implement Earth systems science content and age-appropriate pedagogical methods into their classrooms. The ESSEA semester-long courses are open to elementary, middle school, and high school educators. After three weeks of introductory content, teachers develop content and pedagogical and technological knowledge in four three-week learning cycles. The elementary school course focuses on basic Earth system interactions between land, life, air, and water. The middle school course stresses the effects of real-world events-volcanic eruptions, hurricanes, rainforest destruction-on Earth's lithosphere, atmosphere, biosphere, and hydrosphere, using "jigsaw" to study the interactions between events, spheres, and positive and negative feedback loops. The high school course uses problem-based learning to examine critical areas of global change, such as coral reef degradation, ozone depletion, and climate change. This ESSEA presentation provides examples of learning environments from each of the three courses.

In order to meet the standards, a PETE program needs to have the cooperation of the following three levels of instructors: Specialist Teachers (STs, Inservice Teachers (ITs and Preservice Teachers (PTs. The STs are those who teach at colleges or universities, possess advanced degrees with full/associate/assistant professor titles and teach theoretical and skill courses. They participate in the academic activities of the PETE program; for instance, they serve as academic advisors and instructors of the PTs. The ITs are those who possess teacher certificates, bachelor or higher degrees and currently teach physical education/activity classes at middle/high schools. They also participate in the academic activities; for example, they serve as cooperating teachers providing guidelines and supports for the PTs. The PTs were college students who were studying in a PETE program. They intended to become PE teachers at K-12 school levels. They must complete the student teaching requirements at primary and secondary school class settings in order to graduate from colleges or universities. Approach: The purpose of this study was to examine the differences and similarities of Teaching Behaviors (TB and Learning Activities (LA in Physical Education (PE class settings taught by the three different levels of teachers. Participants were 45 PE teachers from the three levels and their students from a university and three high schools in an urban city of the United States. A total of 90 lessons taught by the three levels of teachers were videotaped and coded using the Direct Instruction Behavior Analysis (DIBA system.

    To determine the distribution and clinical outcome of ocular lesions in snakes. Retrospective case series. 67 snakes with ocular lesions. Signalment, lesion duration, diagnosis, treatment, and clinical outcome were recorded for all snakes with ocular lesions that were examined at a veterinary teaching hospital from 1985 to 2010. 71 ocular lesions were detected in 67 of 508 (13%) snakes examined. Affected snakes were of the families Boidae, Pythonidae, Colubridae, and Viperidae. The distribution of ocular lesions did not vary by taxonomic family, age, or sex; however, snakes from the genus Epicrates with ocular lesions were overrepresented in the population. The most commonly diagnosed ocular lesions were retained spectacle (n = 41), pseudobuphthalmos or subspectacular abscess (13), trauma (8), and cataracts (4). Pseudobuphthalmos or subspectacular abscess developed more frequently in Colubridae than in non-Colubridae snakes. Of the 16 snakes with retained spectacles for which data were available, the lesion recurred once in 4 snakes and multiple times in 5 snakes. Results indicated that retained spectacle was the most common ocular lesion diagnosed in snakes. Compared with other snakes with ocular lesions, snakes of the genus Epicrates had a higher than expected frequency of ocular lesions in general and snakes of the family Colubridae had a higher than expected frequency of pseudobuphthalmos or subspectacular abscess.

  12. Using Multiple Lenses to Examine the Development of Beginning Biology Teachers' Pedagogical Content Knowledge for Teaching Natural Selection Simulations

    2017-03-01

    Pedagogical content knowledge (PCK) has become a useful construct to examine science teacher learning. Yet, researchers conceptualize PCK development in different ways. The purpose of this longitudinal study was to use three analytic lenses to understand the development of three beginning biology teachers' PCK for teaching natural selection simulations. We observed three early-career biology teachers as they taught natural selection in their respective school contexts over two consecutive years. Data consisted of six interviews with each participant. Using the PCK model developed by Magnusson et al. (1999), we examined topic-specific PCK development utilizing three different lenses: (1) expansion of knowledge within an individual knowledge base, (2) integration of knowledge across knowledge bases, and (3) knowledge that explicitly addressed core concepts of natural selection. We found commonalities across the participants, yet each lens was also useful to understand the influence of different factors (e.g., orientation, subject matter preparation, and the idiosyncratic nature of teacher knowledge) on PCK development. This multi-angle approach provides implications for considering the quality of beginning science teachers' knowledge and future research on PCK development. We conclude with an argument that explicitly communicating lenses used to understand PCK development will help the research community compare analytic approaches and better understand the nature of science teacher learning.

    Full Text Available Abstract Background The General Medical Council states that teaching doctors and students is important for the care of patients. Our aim was to deliver a structured teaching program to final year medical students, evaluate the efficacy of teaching given by junior doctors and review the pertinent literature. Methods We developed a revision package for final year medical students sitting the Objective Structured Clinical Examination (OSCE. The package was created and delivered exclusively by recent medical graduates and consisted of lectures and small group seminars covering the core areas of medicine and surgery, with a focus on specific OSCE station examples. Students were asked to complete a feedback questionnaire during and immediately after the program. Results One hundred and eighteen completed feedback questionnaires were analysed. All participants stated that the content covered was relevant to their revision. 73.2% stated that junior doctors delivered teaching that is comparable to that of consultant - led teaching. 97.9% stated the revision course had a positive influence on their learning. Conclusions Our study showed that recent medical graduates are able to create and deliver a structured, formal revision program and provide a unique perspective to exam preparation that was very well received by our student cohort. The role of junior doctors teaching medical students in a formal structured environment is very valuable and should be encouraged.

    With the evolution of education, there has been a shift from the use of traditional teaching methods, such as didactic or rote teaching, towards non-traditional teaching methods, such as viewing of role plays, simulation, live interviews and the use of virtual environments. Mental state examination is an essential competency for all student healthcare professionals. If mental state examination is not taught in the most effective manner so learners can comprehend its concepts and interpret the findings correctly, it could lead to serious repercussions and subsequently impact on clinical care provided for patients with mental health conditions, such as incorrect assessment of suicidal ideation. However, the methods for teaching mental state examination vary widely between countries, academic institutions and clinical settings. This systematic review aimed to identify and synthesize the best available evidence of effective teaching methods used to prepare student health care professionals for the delivery of mental state examination. This review considered evidence from primary quantitative studies which address the effectiveness of a chosen method used for the teaching of mental state examination published in English, including studies that measure learner outcomes, i.e. improved knowledge and skills, self-confidence and learners' satisfaction. A three-step search strategy was undertaken in this review to search for articles published in English from the inception of the database to December 2014. An initial search of MEDLINE and CINAHL was undertaken to identify keywords. Secondly, the keywords identified were used to search electronic databases, namely, CINAHL, Medline, Cochrane Central Register of Controlled Trials, Ovid, PsycINFO and, ProQuest Dissertations & Theses. Thirdly, reference lists of the articles identified in the second stage were searched for other relevant studies. Studies selected were assessed by two independent reviewers for methodological

    Numerous Stirling machines have been built and operated, but the operating experience of these machines is not well known. It is important to examine this operating experience in detail, because it largely substantiates the claim that stirling machines are capable of reliable and lengthy operating lives. The amount of data that exists is impressive, considering that many of the machines that have been built are developmental machines intended to show proof of concept, and are not expected to operate for lengthy periods of time. Some Stirling machines (typically free-piston machines) achieve long life through non-contact bearings, while other Stirling machines (typically kinematic) have achieved long operating lives through regular seal and bearing replacements. In addition to engine and system testing, life testing of critical components is also considered. The record in this paper is not complete, due to the reluctance of some organizations to release operational data and because several organizations were not contacted. The authors intend to repeat this assessment in three years, hoping for even greater participation.

    Full Text Available Abstract Background Development of students' teaching skills is increasingly recognised as an important component of UK undergraduate medical curricula and, in consequence, there is renewed interest in the potential benefits of cross-year peer tutoring. Whilst several studies have described the use of cross-year peer tutoring in undergraduate medical courses, its use in the clinical setting is less well reported, particularly the effects of peer tutoring on volunteer tutors' views of teachers and teaching. This study explored the effects of participation in a cross-year peer tutoring programme in clinical examination skills ('OSCE tutor' on volunteer tutors' own skills and on their attitudes towards teachers and teaching. Methods Volunteer tutors were final year MBChB students who took part in the programme as part of a Student Selected Component (SSC. Tutees were year 3 MBChB students preparing for their end of year 'OSCE' examination. Pre and post participation questionnaires, including both Likert-type and open response questions, were used. Paired data was compared using the Wilcoxon signed-rank test. All tests were two-tailed with 5% significance level. Results Tutors reflected their cohort in terms of gender but were drawn from among the more academically successful final year students. Most had previous teaching experience. They were influenced to participate in 'OSCE tutor' by a desire to improve their own teaching and associated generic skills and by contextual factors relating to the organisation or previous experience of the OSCE tutor programme. Issues relating to longer term career aspirations were less important. After the event, tutors felt that participation had enhanced their skills in various areas, including practical teaching skills, confidence in speaking to groups and communication skills; and that as a result of taking part, they were now more likely to undertake further teacher training and to make teaching a major part

    1997-11-01

    This paper provides a report of the usage of a phenomenological research methodology to investigate the influence on clinical practice of pre- and post-registration nurse education which makes explicit use of experiential teaching and learning approaches. The primary aim of the research was to explore the use of a phenomenological research methodology to examine the students' understanding of experiential teaching and learning. The claims made for the use of experiential teaching and learning approaches in both pre- and post-registration nurse courses and how clinical practice is influenced by the experiential learning elements of pre- and post-registration nurse education were also examined. The first stage of the enquiry involved focused non-directive interviews with members of BSc Nursing Studies and MSc Mental Health Branch programmes. Both programmes claim to make use of experiential teaching and learning. The data were analysed using a technique developed by Giorgi. Previous experiences of experiential teaching and learning were probed, student interpretations differentiated, and the relationship between course-based learning using experiential approaches and the implications for it's influence on practice were examined. The second stage of the enquiry has followed up the initial findings, exploring the students' experience of experiential approaches on their courses both in the classroom and in work-based learning situations. The findings are presented and discussed in the context of other studies from both nurse and higher education. Throughout the paper methodological concerns arising are discussed. The paper concludes with the identification of methodological problems arising from the research strategy: the implications of the power nexus created when teachers research students, and issues relating to the use of a phenomenological methodology in a longitudinal study.

    Wardle, Jonathan Lee; Sarris, Jerome

    2014-06-01

    Complementary medicine is forming an increasingly large part of health care in developed countries and is increasingly being formally taught in tertiary academic settings. An exploratory study of naturopathic student perceptions of, use of and attitudes towards teaching resources in naturopathic clinical training and education. Focus groups were conducted with current and recent students of 4-year naturopathic degree programmes in Brisbane and Sydney to ascertain how they interact with clinical teaching materials, and their perceptions and attitudes towards teaching materials in naturopathic education. Naturopathic students have a complex and critical relationship with their learning materials. Although naturopathic practice is often defined by traditional evidence, students want information that both supports and is critical of traditional naturopathic practices, and focuses heavily on evidence-based medicine. Students remain largely ambivalent about new teaching technologies and would prefer that these develop organically as an evolution from printed materials, rather than depart from dramatically and radically from these previously established materials. Findings from this study will assist publishers, librarians and academics develop clinical information sources that appropriately meet student expectations and support their learning requirements. © 2014 The authors.

    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.

  8. An examination of the perceived teaching competencies of novice alternatively licensed and traditionally licensed high school science teachers

    Science.gov (United States)

    Shea, Kathleen A.

    In most states, there are two routes to teacher licensure; traditional and alternative. The alternative route provides an accelerated entry into the classroom, often without the individual engaging in education coursework or a practicum. No matter the route, teaching skills continue to be learned by novice teachers while in the classroom with the guidance of a school-based mentor. In this study, the perceptions of mentor teachers of traditionally and alternatively licensed high school science teachers were compared with respect to mentees' science teaching competency. Further, the study explored the novice teachers' self-perception of their teaching competency. A survey, consisting of 56 Likert-type questions, was completed by mentors (N = 79) and novice high school science teachers (N = 83) in six northeastern states. The results revealed a statistically significant difference in the perceptions of the mentors of traditionally and alternatively licensed novice high school science teachers in the areas of general pedagogical knowledge, pedagogical content knowledge and professional growth, with more favorable perceptions recorded by mentors of traditionally licensed science teachers. There were no differences in the perceptions of the mentors with respect to novice high school teachers' content knowledge. There was no statistical difference in the self-perceptions of competency of the novice teachers. While alternative routes to licensure in science may be a necessity, the results of this study indicate that the lack of professional preparation may need to be addressed at the school level through the agency of the mentor. This study indicates that mentors must be prepared to provide alternatively licensed novice teachers with different assistance to that given to traditionally licensed novice teachers. School districts are urged to develop mentoring programs designed to develop the teaching competency of all novice teachers regardless of the route that led them

    Although Virtual Machines are widespread across CERN, you probably won't have heard of them unless you work for an experiment. Virtual machines - known as VMs - allow you to create a separate machine within your own, allowing you to run Linux on your Mac, or Windows on your Linux - whatever combination you need.   Using a CERN Virtual Machine, a Linux analysis software runs on a Macbook. When it comes to LHC data, one of the primary issues collaborations face is the diversity of computing environments among collaborators spread across the world. What if an institute cannot run the analysis software because they use different operating systems? "That's where the CernVM project comes in," says Gerardo Ganis, PH-SFT staff member and leader of the CernVM project. "We were able to respond to experimentalists' concerns by providing a virtual machine package that could be used to run experiment software. This way, no matter what hardware they have ...

  10. A qualitative examination of teaching portfolios as a means of transmitting science education values and promoting reflective practice in novice teachers

    Science.gov (United States)

    Doty, Margaret Hawthorne

    Increasing numbers of schools are using teaching portfolios for professional development and evaluation purposes. Several researchers have stated that portfolios foster reflectivity in the teachers who prepare them, and others have found the preparation of portfolios effective in changing teaching behaviors. Current reforms in science education call for teachers to provide opportunities for students to engage in inquiry activities over extended periods of time, placing content in contexts that are relevant to students' everyday lives. Strategies to help teachers revise their practice to bring it into better alignment with the national standards movements are needed. The guidelines for the preparation of a teaching portfolio offer a method by which values about science teaching and learning may be transmitted to novice teachers. This study examined the guidelines for the Connecticut State Department of Education's Beginning Science Teaching Portfolio required of all second-year secondary science teachers to discern what values were embedded. These values were compared to the National Science Education Standards to assess their alignment with current reforms. Four Connecticut science teachers were observed in their classrooms and interviewed before and after the preparation of their teaching portfolios to determine if the quality, quantity and type of reflection changed as they went through the portfolio process. Analysis of the observations, interviews and teaching portfolios determined if their practice changed as a result of the portfolio. It was found that the primary science values reflected in the portfolio guidelines related to the nature of science and the role of the teacher, consistent with the major science standards movements. The teachers in this study changed their practice due to their portfolio preparation, shifting from a more teacher-centered perspective to a more student-centered one, and incorporating more inquiry-based and contextualized content

    2017-01-01

    Machine learning, which builds on ideas in computer science, statistics, and optimization, focuses on developing algorithms to identify patterns and regularities in data, and using these learned patterns to make predictions on new observations. Boosted by its industrial and commercial applications, the field of machine learning is quickly evolving and expanding. Recent advances have seen great success in the realms of computer vision, natural language processing, and broadly in data science. Many of these techniques have already been applied in particle physics, for instance for particle identification, detector monitoring, and the optimization of computer resources. Modern machine learning approaches, such as deep learning, are only just beginning to be applied to the analysis of High Energy Physics data to approach more and more complex problems. These classes will review the framework behind machine learning and discuss recent developments in the field.

  15. Examining the pedagogical content knowledge and practice of experienced secondary biology teachers for teaching diffusion and osmosis

    Science.gov (United States)

    Lankford, Deanna

    Teachers are the most important factor in student learning (National Research Council, 1996); yet little is known about the specialized knowledge held by experienced teachers. The purpose of this study was twofold: first, to make explicit the pedagogical content knowledge (PCK) for teaching diffusion and osmosis held by experienced biology teachers and, second, to reveal how topic-specific PCK informs teacher practice. The Magnusson et al. (1999) PCK model served as the theoretical framework for the study. The overarching research question was: When teaching lessons on osmosis and diffusion, how do experienced biology teachers draw upon their topic-specific pedagogical content knowledge? Data sources included observations of two consecutive lessons, three semi-structured interviews, lesson plans, and student handouts. Data analysis indicated five of the six teachers held a constructivist orientation to science teaching and engaged students in explorations of diffusion and osmosis prior to introducing the concepts to students. Explanations for diffusion and osmosis were based upon students' observations and experiences during explorations. All six teachers used representations at the molecular, cellular, and plant organ levels to serve as foci for explorations of diffusion and osmosis. Three potential learning difficulties identified by the teachers included: (a) understanding vocabulary terms, (b) predicting the direction of osmosis, and (c) identifying random molecular motion as the driving force for diffusion and osmosis. Participants used student predictions as formative assessments to reveal misconceptions before instruction and evaluate conceptual understanding during instruction. This study includes implications for teacher preparation, research, and policy.

  18. Data-mining to build a knowledge representation store for clinical decision support. Studies on curation and validation based on machine performance in multiple choice medical licensing examinations.

    Science.gov (United States)

    Robson, Barry; Boray, Srinidhi

    2016-06-01

    Extracting medical knowledge by structured data mining of many medical records and from unstructured data mining of natural language source text on the Internet will become increasingly important for clinical decision support. Output from these sources can be transformed into large numbers of elements of knowledge in a Knowledge Representation Store (KRS), here using the notation and to some extent the algebraic principles of the Q-UEL Web-based universal exchange and inference language described previously, rooted in Dirac notation from quantum mechanics and linguistic theory. In a KRS, semantic structures or statements about the world of interest to medicine are analogous to natural language sentences seen as formed from noun phrases separated by verbs, prepositions and other descriptions of relationships. A convenient method of testing and better curating these elements of knowledge is by having the computer use them to take the test of a multiple choice medical licensing examination. It is a venture which perhaps tells us almost as much about the reasoning of students and examiners as it does about the requirements for Artificial Intelligence as employed in clinical decision making. It emphasizes the role of context and of contextual probabilities as opposed to the more familiar intrinsic probabilities, and of a preliminary form of logic that we call presyllogistic reasoning.

  19. An exploratory examination of Islamic values in science education: Islamization of science teaching and learning via constructivism

    2014-12-01

    This exploratory study outlines the perceptions of four Muslim graduate students regarding Islam and its influence on their approach to the teaching and learning of science. All of the four interviewees were enrolled in science related programmes at a Midwestern US university. The interview responses were evaluated both within the frame of the Islamization of science and Ian Barbour's (When science meets religion: enemies, strangers, or partners?, Harper, San Francisco, 2000) classification, which is based on four categories; conflict, independence, dialogue, and integration. Interviews were semi-structured and the data analyzed using a framework of typological and interpretive approaches (Hatch in Doing qualitative research in education settings, State University of New York Press, New York, 2002). The interview findings show that Barbour's classification is a useful tool for categorizing perceptions. However, these perceptions may fall into more than one category. A surprising side effect was the misinterpretation and misuse of constructivism as well as the notion of a scientific theory as ways to negate the theory of evolution, and promote the teaching of intelligent design. These misinterpretations and misuses occur because there is the belief that the interaction between science and religion in daily life is considered part of the cultural setting in Islamic countries, which is what students bring to the table, as well as the notion that reality can only be found in the Qur'an.

    2014-05-01

    The American Nurses Association advocates for nursing professional development (NPD) specialists to have an earned graduate degree, as well as educational and clinical expertise. However, many NPD specialists have limited exposure to adult learning theory. Limited exposure to adult learning theory may affect NPD educational practices, learning outcomes, organizational knowledge transfer, and subsequently, the professional development of the nurses they serve and quality of nursing care. An examination of current teaching practices may reveal opportunities for NPD specialists to enhance educational methods to promote learning, learning transfer, and organizational knowledge and excellence. This article, the first in a two-part series, examines best practices of adult learning theories, nursing professional development, curriculum design, and knowledge transfer. Part II details the results of a correlational study that examined the effects of four variables on the use of adult learning theory to guide curriculum development for NPD specialists in hospitals.

    The absence of a robust and unified theory of cyber dynamics presents challenges and opportunities for using machine learning based data-driven approaches to further the understanding of the behavior of such complex systems. Analysts can also use machine learning approaches to gain operational insights. In order to be operationally beneficial, cybersecurity machine learning based models need to have the ability to: (1) represent a real-world system, (2) infer system properties, and (3) learn and adapt based on expert knowledge and observations. Probabilistic models and Probabilistic graphical models provide these necessary properties and are further explored in this chapter. Bayesian Networks and Hidden Markov Models are introduced as an example of a widely used data driven classification/modeling strategy.

    Okech, Allan P.

    The purpose of the study was to examine the relationships among emotional intelligence, teacher self-efficacy, length of teaching experience, and age in a sample of south Texas public school teachers. Additionally, the study examined differences in emotional intelligence between male teachers and female teachers, and among African American, Hispanics, and White teachers. Participants were 180 elementary science teachers from south Texas public schools. The sample was made up of 14 (7.8%) males and 166 (92.2%) females. Regarding race/ethnicity, the study sample consisted of 31 (17.2%) African Americans (3 males and 28 females), 49 (27.2) Hispanics (7 males and 42 females), 98 (54.4%) Whites (3 males and 95 females), and 2 (1.1%) "Other" (1 male and 1 female). Participants ranged in age from 23 years to 65 years. Five hypotheses were proposed and tested to address the relationships under investigation. The study employed a mixed methods---correlational and causal-comparative---research design approach. Three instruments, the Multifactor Emotional Intelligence Scale (Mayer, Caruso, & Salovey, 1999), the Science Teaching Efficacy Beliefs Instrument (Riggs & Enochs, 1990), and a demographics questionnaire were utilized to collect the data. An independent-measures t test, the Pearson r, and the one-way MANOVA were used to analyze the data. A Significant positive relationship was found between "emotional intelligence" and "teacher self-efficacy." Data analyses, however, failed to support hypothesized relationships between "emotional intelligence" and "length of teaching experience," and between "emotional intelligence" and "age". Additionally, statistical analyses of the data collected for this study supported predicted statistically significant differences in "emotional intelligence" between male and female teachers, and among the three race/ethnicity groupings. Based on these findings, recommendations for the application of the construct of "emotional intelligence" in

  19. Where is the "self" in teacher self-assessment? An examination of teachers' reflection and assessment practices in relation to their teaching practices

    Science.gov (United States)

    Madsen, Andrea Jean

    The purpose of this study was to identify the levels of explicit reflection-on-action and criteria with which teachers self-assess their teaching, and to compare these levels and criteria to classroom practices. These reflections and practices were then compared to the participants' preservice preparation to determine the extent to which strategies taught transferred to classroom practice. To investigate these issues, this study utilized classroom observations, interviews, and relevant documents from thirteen second-, third-, fourth-, or fifth-year teachers who had graduated from a traditional elementary teacher education program at a landgrant university in the Midwestern United States. Classroom observations were rated using the Local Systemic Change Observation Protocol (Horizon Research, 2004). Teacher interviews examined the criteria teachers consider, as well as the reasoning and reflection they use to make sense of the assessment criteria and their classroom decisions. Interviews were coded using the five reflection levels used by Manouchehri (2002). This study responds to Kagan's (1990) concern about the lack of information linking reflection to practice, and provides evidence that such a relationship exists. This relationship is most evident in the use of theory. Only the most effective teachers spoke of theory and educational literature, and their use in personal teaching practices. In addition, the content and focus of teachers' reflections differed markedly as teachers demonstrated more effective teaching practices. Even though self-assessment and reflection practices were taught to the participants of this study during their preservice education program, such knowledge bases were often implemented in a piecemeal fashion, particularly by the least effective teachers in this study. Only the most effective teachers in this study implement self-assessment practices in ways that will most likely lead to changes consistent with current reform documents

    Medical educators have always recognized the need to teach and train medical graduates and undergraduates the skills of conducting a consultation. Several authors have established the efficacy of using constructive feedback on videotape of each student's interaction with a patient to teach and enhance such skills. This study reports 'students' perceptions' of the feedback process used in the Junior Paediatric Clerkship at the Faculty of Medicine of the United Arab Emirates University. An unexpected 73% of the respondents believed that self-observation influenced development of their clinical skills. More than 80% said that the feedback from instructors and peers helped them to improve their clinical skills, but they would have liked to have more than one of their consultations recorded and reviewed. It was found that 75% of the students felt that self-critique of their performance made them aware of their strengths and weaknesses and their skills in analysing and evaluating consultations had been enhanced. It was found from Kruskal Wallis one-way ANOVA that the students' professional attitude, empathy, and warmth towards the patients differed highly significantly (P = 0.0062, 0.0089, 0.0007, respectively) from self-assurance, self-confidence and competence. They were also deficient in certain areas of history-taking, interviewing skills, and physical examination techniques and perceived they needed more training in order to be proficient.

    Dresang, Lee T; Rodney, William MacMillan; Dees, Jason

    2004-02-01

    Prenatal ultrasound is a powerful diagnostic tool, but there has been little research on how to teach ultrasound to family physicians. The available evidence supports teaching through didactics followed by supervised scanning. Didactic topics include physics and machine usage, indications, fetal biometry, anatomic survey, practice management, ethical issues, and resources. Supervised scanning reinforces the didactic components of training. A "hand-on-hand" supervised scanning technique is recommended for the transmission of psychomotor skills in these sessions. Curricula for teaching ultrasound should include information on which residents will be taught prenatal ultrasound, who will teach them, how to create time for learning ultrasound skills, and how to test for competency. The literature suggests that competency can be achieved within 25-50 supervised scans. Measures of competency include examination and qualitative analysis of scanning. Competency-based testing needs further development because no uniform standards have been established.

    A preliminary audit of orders for computed tomography was performed to evaluate the typical performance of interns ordering radiologic examinations. According to the audit, the interns showed only minimal improvement after 8 months of work experience. The online radiology ordering module (ROM) program included baseline assessment of student performance (part I), online learning with the ROM (part II), and follow-up assessment of performance with simulated ordering with the ROM (part III). A curriculum blueprint determined the content of the ROM program, with an emphasis on practical issues, including provision of logistic information, clinical details, and safety-related information. Appropriate standards were developed by a committee of experts, and detailed scoring systems were devised for assessment. The ROM program was successful in addressing practical issues in a simulated setting. In the part I assessment, the mean score for noting contraindications for contrast media was 24%; this score increased to 59% in the part III assessment (P = .004). Similarly, notification of methicillin-resistant Staphylococcus aureus status and pregnancy status and provision of referring physician contact information improved significantly. The quality of the clinical notes was stable, with good initial scores. Part III testing showed overall improvement, with the mean score increasing from 61% to 76% (P radiology services, and the experience typically afforded to interns does not address this lack of knowledge. The ROM program was a successful intervention that resulted in statistically significant improvements in the quality of radiologic examination orders, particularly with regard to logistic and radiation safety issues.

The ROM program was a successful intervention that resulted in statistically significant improvements in the quality of radiologic examination orders, particularly with regard to logistic and radiation safety issues.

  11. Machine Transliteration

    Knight, K; Knight, Kevin; Graehl, Jonathan

    1997-01-01

    It is challenging to translate names and technical terms across languages with different alphabets and sound inventories. These items are commonly transliterated, i.e., replaced with approximate phonetic equivalents. For example, "computer" in English comes out as "konpyuutaa" in Japanese. Translating such items from Japanese back to English is even more challenging, and of practical interest, as transliterated items make up the bulk of text phrases not found in bilingual dictionaries. We describe and evaluate a method for performing backwards transliterations by machine. This method uses a generative model, incorporating several distinct stages in the transliteration process.

    Full Text Available Breast cancer is the most common female malignancy linked with high levels of morbidity and mortality in developing countries due to delayed diagnosis. This research assessed the knowledge of signs and risk factors of breast cancer and practice of self breast examination (SBE among female nurses in a rural tertiary Hospital. Eighty-five nurses ages 20 to 60 years were sampled by simple randomization over a period of eight weeks through a self-administered semi-structured questionnaire. The analysis was done using statistical package for social science version 17. Sixteen (15.3% nurses had adequate knowledge of breast cancer, having a relative with breast cancer (51.8% and a woman of any age (56.5% were recognized by majority as risk factors for breast cancer. Majority (68.2% were not practicing monthly SBE and not confident on how to do it. This study pointed out the gaps in the knowledge and awareness of breast cancer and practice of SBE among the nurses. Opportunity should therefore be sought in various health facilities to educate nurses who are supposed to be closer to the patients.

  15. Machine Protection

    CERN Document Server

    Schmidt, R

    2014-01-01

    The protection of accelerator equipment is as old as accelerator technology and was for many years related to high-power equipment. Examples are the protection of powering equipment from overheating (magnets, power converters, high-current cables), of superconducting magnets from damage after a quench and of klystrons. The protection of equipment from beam accidents is more recent. It is related to the increasing beam power of high-power proton accelerators such as ISIS, SNS, ESS and the PSI cyclotron, to the emission of synchrotron light by electron–positron accelerators and FELs, and to the increase of energy stored in the beam (in particular for hadron colliders such as LHC). Designing a machine protection system requires an excellent understanding of accelerator physics and operation to anticipate possible failures that could lead to damage. Machine protection includes beam and equipment monitoring, a system to safely stop beam operation (e.g. dumping the beam or stopping the beam at low energy) and an ...

    Hintergrund: Ein OSCE (objective structured clinical examination) ist zusammengestellt aus mündlichen und praktischen Prüfungen um die studentischen Fähigkeiten der klinischen Untersuchung und des Umgangs mit den Patienten zu beurteilen. Als Prüfer können dabei Peers und Dozenten eingesetzt werden. In dieser Arbeit werden studentische „Skills-Lab“-Tutoren als Prüfer einer OSCE-Station Orthopädie evaluiert.Methoden: Wir analysierten die Zahlen der OSCEs von 2013 bis 2015. In jedem Jahr wurden mehr als 300 Studenten geprüft. Die Prüfungsergebnisse nach Einsatz von studentischen „Skills-Lab“-Tutoren als Prüfer einer OSCE-Station Orthopädie werden ausgewertet.Ergebnisse: Die Auswertung der studentischen Peers in unserer Studie zeigt, dass sie flexibler in der zeitlichen Planung sind und gut auf den OSCE vorbereitet waren. Zudem haben studentische Peers einen klaren ökonomischen Vorteil.Nachteile wurden in unserer Untersuchung nicht festgestellt, was mit dem Fakt zusammenhängen kann, dass die Peers gut vorbreitet wurden und die Checklisten regelmäßig überprüft werden. Schlussfolgerung: Studentische Peers im OSCE haben große Vorteile durch ihre zeitliche Flexibilität und relativ geringe Kosten. Sie müssen gut vorbereitet werden und die Checklisten müssen regelmäßig geprüft werden. In den ausgewerteten Prüfungsergebnissen zeigt sich kein Unterschied zwischen studentischen und ärztlichen Prüfern. Die gesetzlichen Grundlagen für den Einsatz von Studenten sollten bedacht werden.

    The National Ranking Examination (NRE) is the key to the choice of career and specialty for future physicians; it lets them choose their place of employment in a specialty and an hospital for their internship. It seems interesting to model the success factors to this exam for the medical students from Grenoble University. For each of the medical students at Grenoble University who did apply to the NRE in 2012, data have been collected about their academic background and personal details from the administration of the University. A simple logistic regression with success set as being ranked in the first 2000 students, then a polytomous logistic regression, have been performed. The 191 students in the models are 59% female, 25 years old in average (SD 1.8). The factors associated to a ranking in the first 2000 are: not repeating the PCEM1 class (odds ratio [OR] 2.63, CI95: [1.26; 5.56]), performing nurse practice during internships (OR=1.27 [1.00; 1.62]), being ranked in the first half of the class for S3 pole (OR=6.04 [1.21; 30.20] for the first quarter, OR=5.65 [1.15; 27.74] for the second quarter) and being in the first quarter at T5 pole (OR=3.42 [1.08; 10.82]). Our study finds four factors independently contributing to the success at NRE: not repeating PCEM1, performing nurse practice and being ranked in the top of the class at certain academic fields. The AUC is 0.76 and student accuracy is more than 80%. However, some items, for example repeating DCEM4 or participating in NRE mock exams, have no influence on success. A different motivation should be a part of the explanation… As these analysed data are mainly institutional, they are accurate and reliable. The polytomic logistic model, sharing 3 factors with the simple logistic model, replace a performing nurse practice factor's by a grant recipient factor. Copyright © 2015 Elsevier Masson SAS.

    2016-01-01

    Full Text Available Background: Breast cancer (BC continues to be a major cause of morbidity and mortality throughout the world. Early detection of BC and early treatment increases the chance of survival. According to Breast Health Global Initiative guidelines for low and middle income countries, diagnosing BCs early by promoting breast self-awareness; clinical breast examination (CBE and resource adapted mammographic screening will reduce BC mortality. There is a paucity of data on the knowledge and awareness of BC and self-breast examination in India. We designed this hospital based cross sectional descriptive study to evaluate the current status of knowledge, awareness and practices related to BC and breast self-examination in the female rural population attending a teaching hospital. Materials and Methods: We did a random sampling to identify and enroll 360 women and their female relatives. We excluded a participant from the study if she had already undergone a screening mammography or had had a BC. The data was collected by a self-administered questionnaire in vernacular language. Results: Our study population included 360 women with a mean age of 45.81 (±10.9 years. Only 5 (1.38% females had a family history of BC. A whopping 81% of women did not have any knowledge about BC. All the women thought that CBE by doctors was the only way for screening BC. Conclusions: We concluded that with the results of this study, it is imperative to increase awareness about BC and its detection methods in the community through health education campaigns. We should have major policy changes to increase future screening programs and health education programs which would have an overall positive impact on reducing the disease burden.

    Full Text Available The key technique of manufacturing methods is machining. The degree of technique of machining directly affects the quality of the product. Therefore, the machining technique is of primary importance in promoting student practice ability during the training process. Currently, practical training is applied in shop floor to discipline student’s practice ability. Much time and cost are used to teach these techniques. Particularly, computerized machines are continuously increasing in use. The development of educating engineers on computerized machines becomes much more difficult than with traditional machines. This is because of the limitation of the extremely expensive cost of teaching. The quality and quantity of teaching cannot always be promoted in this respect. The traditional teaching methods can not respond well to the needs of the future. Therefore, this research aims to the following topics; (1.Propose the teaching strategies for the students to learning machining processing planning through web-based learning system. (2.Establish on-line teaching material for the computer-aided manufacturing courses including CNC coding method, CNC simulation. (3.Develop the virtual machining laboratory to bring the machining practical training to web-based learning system. (4.Integrate multi-media and virtual laboratory in the developed e-learning web-based system to enhance the effectiveness of machining education through web-based system.

    The development of optical engineering, photonics, optical telecommunications and networking courses in the Carlow Institute of Technology are briefly outlined in its national and local historic context. The experience of running various pioneering technician and degree courses in Carlow using assessment procedures designed to test specified learning outcomes is described. A critical review of the use of these educational methods for optical engineering is then made based on the personal experience of one of the author's postgraduate experience in studying in both the Glasgow universities. A differential study is presented of the Scottish and Irish experience, made from the point of view of best practice in educational methodology, as it applies specifically to teaching the high level skills required for engineering design in optical engineering programmes. Details on technology teacher training are presented and some discussion is given on relevant educational initiatives for this area. Possibly the first ever quantitative taxonometric analysis of the 2003-4 examination papers from a leading Institute of Technology in Ireland is undertaken to provide an insight into the present practice of the lecturers and educational managers running this programme. This analysis reveals the coordinated teamwork involved in the course implementation and identifies that various roles that are taken by individual courses in the context of balancing appropriately the whole educational programme. Critical observations on some of the programmes for technician, technologist and degree programmes should enable the delivery to be improved. The statistical analysis of results should also deliver improvements in retention rates of the students. The paper ends with a observations on some useful lessons to be drawn from this wide-ranging review of world, Scottish and Irish experience.

    Some beryllium processes, especially machining, are associated with an increased risk of beryllium sensitization and disease. Little is known about exposure characteristics contributing to risk, such as particle size. This study examined the characteristics of beryllium machining exposures under actual working conditions. Stationary samples, using eight-stage Lovelace Multijet Cascade Impactors, were taken at the process point of operation and at the closest point that the worker would routinely approach. Paired samples were collected at the operator's breathing zone by using a Marple Personal Cascade Impactor and a 35-mm closed-faced cassette. More than 50% of the beryllium machining particles in the breathing zone were less than 10 microns in aerodynamic diameter. This small particle size may result in beryllium deposition into the deepest portion of the lung and may explain elevated rates of sensitization among beryllium machinists.

    2015-01-01

    The essays in this book, written by researchers from both humanities and sciences, describe various theoretical and experimental approaches to adding medical ethics to a machine in medical settings. Medical machines are in close proximity with human beings, and getting closer: with patients who are in vulnerable states of health, who have disabilities of various kinds, with the very young or very old, and with medical professionals. In such contexts, machines are undertaking important medical tasks that require emotional sensitivity, knowledge of medical codes, human dignity, and privacy. As machine technology advances, ethical concerns become more urgent: should medical machines be programmed to follow a code of medical ethics? What theory or theories should constrain medical machine conduct? What design features are required? Should machines share responsibility with humans for the ethical consequences of medical actions? How ought clinical relationships involving machines to be modeled? Is a capacity for e...

    The purpose of this study was to investigate the effect of repeated machining up to 51 times using the same diamond bur on machining accuracy of inner and outer surfaces of CAD/CAM (computer-aided designing and computer-aided manufacturing) machined ceramic crowns. The surface topography of machined crowns was examined using photographs. It was found that machining accuracy was not affected by the number of machining times. In all measuring points, the inner surface was machined to a dimension larger than the die model (i.e., increased gap), whereas the outer surface was machined to a dimension smaller than the crown model (i.e., smaller crown). Photo observation showed that cervical contour was machined in a clear, rounded form from 1st to 11th crowns.

    Fuelled by increasing computer power and algorithmic advances, machine learning techniques have become powerful tools for finding patterns in data. Quantum systems produce atypical patterns that classical systems are thought not to produce efficiently, so it is reasonable to postulate that quantum computers may outperform classical computers on machine learning tasks. The field of quantum machine learning explores how to devise and implement quantum software that could enable machine learning that is faster than that of classical computers. Recent work has produced quantum algorithms that could act as the building blocks of machine learning programs, but the hardware and software challenges are still considerable.

  2. Teaching People and Machines to Enhance Images

    Science.gov (United States)

    Berthouzoz, Floraine Sara Martianne

    Procedural tasks such as following a recipe or editing an image are very common. They require a person to execute a sequence of operations (e.g. chop onions, or sharpen the image) in order to achieve the goal of the task. People commonly use step-by-step tutorials to learn these tasks. We focus on software tutorials, more specifically photo manipulation tutorials, and present a set of tools and techniques to help people learn, compare and automate photo manipulation procedures. We describe three different systems that are each designed to help with a different stage in acquiring procedural knowledge. Today, people primarily rely on hand-crafted tutorials in books and on websites to learn photo manipulation procedures. However, putting together a high quality step-by-step tutorial is a time-consuming process. As a consequence, many online tutorials are poorly designed which can lead to confusion and slow down the learning process. We present a demonstration-based system for automatically generating succinct step-by-step visual tutorials of photo manipulations. An author first demonstrates the manipulation using an instrumented version of GIMP (GNU Image Manipulation Program) that records all changes in interface and application state. From the example recording, our system automatically generates tutorials that illustrate the manipulation using images, text, and annotations. It leverages automated image labeling (recognition of facial features and outdoor scene structures in our implementation) to generate more precise text descriptions of many of the steps in the tutorials. A user study finds that our tutorials are effective for learning the steps of a procedure; users are 20-44% faster and make 60-95% fewer errors when using our tutorials than when using screencapture video tutorials or hand-designed tutorials. We also demonstrate a new interface that allows learners to navigate, explore and compare large collections (i.e. thousands) of photo manipulation tutorials based on their command-level structure. Sites such as tutorialized.com or good-tutorials.com collect tens of thousands of photo manipulation tutorials. These collections typically contain many different tutorials for the same task. For example, there are many different tutorials that describe how to recolor the hair of a person in an image. Learners often want to compare these tutorials to understand the different ways a task can be done. They may also want to identify common strategies that are used across tutorials for a variety of tasks. However, the large number of tutorials in these collections and their inconsistent formats can make it difficult for users to systematically explore and compare them. Current tutorial collections do not exploit the underlying command-level structure of tutorials, and to explore the collection users have to either page through long lists of tutorial titles or perform keyword searches on the natural language tutorial text. We present a new browsing interface to help learners navigate, explore and compare collections of photo manipulation tutorials based on their command-level structure. Our browser indexes tutorials by their commands, identifies common strategies within the tutorial collection, and highlights the similarities and differences between sets of tutorials that execute the same task. User feedback suggests that our interface is easy to understand and use, and that users find command-level browsing to be useful for exploring large tutorial collections. They strongly preferred to explore tutorial collections with our browser over keyword search. Finally, we present a framework for generating content-adaptive macros (programs) that can transfer complex photo manipulation procedures to new target images. After learners master a photo manipulation procedure, they often repeatedly apply it to multiple images. For example, they might routinely apply the same vignetting effect to all their photographs. This process can be very tedious especially for procedures that involve many steps. While image manipulation programs pro

  3. Perspex machine: VII. The universal perspex machine

    Science.gov (United States)

    Anderson, James A. D. W.

    2006-01-01

    The perspex machine arose from the unification of projective geometry with the Turing machine. It uses a total arithmetic, called transreal arithmetic, that contains real arithmetic and allows division by zero. Transreal arithmetic is redefined here. The new arithmetic has both a positive and a negative infinity which lie at the extremes of the number line, and a number nullity that lies off the number line. We prove that nullity, 0/0, is a number. Hence a number may have one of four signs: negative, zero, positive, or nullity. It is, therefore, impossible to encode the sign of a number in one bit, as floating-point arithmetic attempts to do, resulting in the difficulty of having both positive and negative zeros and NaNs. Transrational arithmetic is consistent with Cantor arithmetic. In an extension to real arithmetic, the product of zero, an infinity, or nullity with its reciprocal is nullity, not unity. This avoids the usual contradictions that follow from allowing division by zero. Transreal arithmetic has a fixed algebraic structure and does not admit options as IEEE, floating-point arithmetic does. Most significantly, nullity has a simple semantics that is related to zero. Zero means "no value" and nullity means "no information." We argue that nullity is as useful to a manufactured computer as zero is to a human computer. The perspex machine is intended to offer one solution to the mind-body problem by showing how the computable aspects of mind and, perhaps, the whole of mind relates to the geometrical aspects of body and, perhaps, the whole of body. We review some of Turing's writings and show that he held the view that his machine has spatial properties. In particular, that it has the property of being a 7D lattice of compact spaces. Thus, we read Turing as believing that his machine relates computation to geometrical bodies. We simplify the perspex machine by substituting an augmented Euclidean geometry for projective geometry. This leads to a general

  4. A language for easy and efficient modeling of Turing machines

    2007-01-01

    A Turing Machine Description Language (TMDL) is developed for easy and efficient modeling of Turing machines.TMDL supports formal symbolic representation of Turing machines. The grammar for the language is also provided. Then a fast singlepass compiler is developed for TMDL. The scope of code optimization in the compiler is examined. An interpreter is used to simulate the exact behavior of the compiled Turing machines. A dynamically allocated and resizable array is used to simulate the infinite tape of a Turing machine. The procedure for simulating composite Turing machines is also explained. In this paper, two sample Turing machines have been designed in TMDL and their simulations are discussed. The TMDL can be extended to model the different variations of the standard Turing machine.

    2013-01-01

    The chaotic Boltzmann machine proposed in this paper is a chaotic pseudo-billiard system that works as a Boltzmann machine. Chaotic Boltzmann machines are shown numerically to have computing abilities comparable to conventional (stochastic) Boltzmann machines. Since no randomness is required, efficient hardware implementation is expected. Moreover, the ferromagnetic phase transition of the Ising model is shown to be characterised by the largest Lyapunov exponent of the proposed system. In general, a method to relate probabilistic models to nonlinear dynamics by derandomising Gibbs sampling is presented.

  13. Debugging the virtual machine

    Energy Technology Data Exchange (ETDEWEB)

    Miller, P.; Pizzi, R.

    1994-09-02

    A computer program is really nothing more than a virtual machine built to perform a task. The program`s source code expresses abstract constructs using low level language features. When a virtual machine breaks, it can be very difficult to debug because typical debuggers provide only low level machine implementation in formation to the software engineer. We believe that the debugging task can be simplified by introducing aspects of the abstract design into the source code. We introduce OODIE, an object-oriented language extension that allows programmers to specify a virtual debugging environment which includes the design and abstract data types of the virtual machine.

    Full Text Available Coordination, as the basic motor ability, is very complex, as the level of the movement regulation can change. In addition, the regulation includes energetic mechanisms as well as mechanisms of simple structuring of movement. The battery for the evaluation of coordination consists of the following tests: MPON, MSL3, MONT. During the 2005/06 academic year, a research was conducted so as to determine the effects of current program of physical education teaching on motor abilities coordination of female pupils. The multi-variant procedures were used in this research ant those were: the multi-variant analysis of the variable MANCOVA, MANOVA and the discriminative analysis. Also, the mono-variant procedures were used and those were: the variable analysis ANCOVA, ANOVA and the interval of entrust. After the experimental treatment, i.e. at the final testing, significant differences were found with female pupils in experimental and control groups concerning the all tests for the evaluation of coordination. The basic conclusion is that the female pupils of experimental group achieved significantly higher teaching effects than the control group, in view of partly increased motor abilities, being the result of the effects of the experimental treatment, as well as other external and internal factors.

As the outcome of this research, a methodology comprising of an Ergonomic Gap Analysis Matrix for machine abnormality detection is presented.

  19. Virtual machine vs Real Machine: Security Systems

    Directory of Open Access Journals (Sweden)

    Dr. C. Suresh Gnana Das

    2009-08-01

    Full Text Available This paper argues that the operating system and applications currently running on a real machine should relocate into a virtual machine. This structure enables services to be added below the operating system and to do so without trusting or modifying the operating system or applications. To demonstrate the usefulness of this structure, we describe three services that take advantage of it: secure logging, intrusion prevention and detection, and environment migration. In particular, we can provide services below the guest operating system without trusting or modifying it. We believe providing services at this layer are especially useful for enhancing security and mobility. This position paper describes the general benefits and challenges that arise from running most applications in a virtual machine, and then describes some example services and alternative ways to provide those services.

  1. Rotating electrical machines: Poynting flow

    Science.gov (United States)

    Donaghy-Spargo, C.

    2017-09-01

    This paper presents a complementary approach to the traditional Lorentz and Faraday approaches that are typically adopted in the classroom when teaching the fundamentals of electrical machines—motors and generators. The approach adopted is based upon the Poynting vector, which illustrates the ‘flow’ of electromagnetic energy. It is shown through simple vector analysis that the energy-flux density flow approach can provide insight into the operation of electrical machines and it is also shown that the results are in agreement with conventional Maxwell stress-based theory. The advantage of this approach is its complementary completion of the physical picture regarding the electromechanical energy conversion process—it is also a means of maintaining student interest in this subject and as an unconventional application of the Poynting vector during normal study of electromagnetism.

    2008-01-01

    Full Text Available Ever since the first century A.D. there have been relative descriptions of known devices as well as manufactures for the creation of perpetual motion machines. Although physics has led, with two thermodynamic laws, to the opinion that a perpetual motion machine is impossible to be manufactured, inventors of every age and educational level appear to claim that they have invented something «entirely new» or they have improved somebody else’s invention, which «will function henceforth perpetually»! However the fact of the failure in manufacturing a perpetual motion machine till now, it does not mean that countless historical elements for these fictional machines become indifferent. The discussion on every version of a perpetual motion machine on the one hand gives the chance to comprehend the inventor’s of each period level of knowledge and his way of thinking, and on the other hand, to locate the points where this «perpetual motion machine» clashes with the laws of nature and that’s why it is impossible to have been manufactured or have functioned. The presentation of a new «perpetual motion machine» has excited our interest to locate its weak points. According to the designer of it the machine functions with the work produced by the buoyant force

    A four-state random stimulus generator, considered to function as an ESP teaching machine was used to investigate an approach to facilitating interactions between man and machines. A subject tries to guess in which of four states the machine is. The machine offers the user feedback and reinforcement as to the correctness of his choice. Using this machine, 148 volunteer subjects were screened under various protocols. Several whose learning slope and/or mean score departed significantly from chance expectation were identified. Direct physiological evidence of perception of remote stimuli not presented to any known sense of the percipient using electroencephalographic (EEG) output when a light was flashed in a distant room was also studied.

    2012-08-28

    Manipulating bulk material at the atomic level is considered to be the domain of physics, chemistry and nanotechnology. However, precision engineering, especially micro-machining, has become a powerful tool for controlling the surface properties and sub-surface integrity of the optical, electronic and mechanical functional parts in a regime where continuum mechanics is left behind and the quantum nature of matter comes into play. The surprising subtlety of micro-machining results from the extraordinary precision of tools, machines and controls expanding into the nanometre range-a hundred times more precise than the wavelength of light. In this paper, we will outline the development of precision engineering, highlight modern achievements of ultra-precision machining and discuss the necessity of a deeper physical understanding of micro-machining.

    The machine learning field, which can be briefly defined as enabling computers make successful predictions using past experiences, has exhibited an impressive development recently with the help of the rapid increase in the storage capacity and processing power of computers. Together with many other disciplines, machine learning methods have been widely employed in bioinformatics. The difficulties and cost of biological analyses have led to the development of sophisticated machine learning approaches for this application area. In this chapter, we first review the fundamental concepts of machine learning such as feature assessment, unsupervised versus supervised learning and types of classification. Then, we point out the main issues of designing machine learning experiments and their performance evaluation. Finally, we introduce some supervised learning methods.

    Physics is an experiment-based discipline, and exper-iments go through the whole senior high school physics teaching. With the continuous reform of China's educational system, more and more attention has been given to senior high school experi-ments by schools and teachers under the new curriculum system. Physics experiments are not only reflected in routine teaching, but also occupy a large proportion in college entrance examination. Therefore, physics experiment teaching should be enhanced in senior high schools, so as to cultivate students' awareness of ex-periment, and improve their experimental ability, thus making them achieve prominent scores in college entrance examination and providing a powerful guarantee for national talent cultivation and college enrollment.%物理是一门实验学科,在高中物理教学中,实验一直贯穿于物理教学的始终。随着近年来我国教育体系的不断改革,在新课标体系下,学校和老师越来越重视高中物理实验。物理实验不仅仅体现在平时的教学中,在高考物理中占据的分数比例也非常大。因此,学校应该加强高中物理实验教学,培养学生的实验意识,提高学生的实验能力水平,从而在高考中取得优异的成绩,为国家人才培养和高等学校录取人才提供强有力的保证。

  1. The Ethical Examination on the Teaching Model of Flipped Classroom%翻转课堂教学模式的伦理省思

    2015-01-01

    In ICT environment, flipped classroom has been a boom in the field of education at home and abroad. Studying flipped classroom from the perspective of ethics is to highlight its ethical value and ethical way of healthy development by analyzing the ethical characteristics of flipped classroom. Flipped classroom is firstly discussed from three aspects including learning concept, learning quality and learning services. Then the reasons why flipped classroom is so heated are further explored. It is found that flipped classroom has changed the traditional teaching struc ture and encouraged people to rethink the teachers' and students' roles played in the learning process, but there are still some deficiencies in teaching practice because of lack of educational big data col-lected from long-term empirical researches. Flipped classroom should respect students' personality differences, define teacher's role reasonably and have complete ethics standard. In a word, a rational knowledge of flipped classroom should be acquired.%在信息化境遇下,翻转课堂正在东西方教育领域中掀起一股热潮。以伦理学的视角对翻转课堂进行思考,旨在通过对翻转课堂伦理品性的分析,彰显其伦理价值及良性发展的伦理途径。从学习理念、学习服务和学习质量三个方面对翻转课堂进行了伦理考量,并对促成当前翻转课堂热的动因进行了冷静的剖析。虽然翻转课堂改变了传统教学结构,并促使人们对学习过程中教师和学生的角色进行重新思考定位,但有关翻转课堂的教学研究还缺乏长期基于教育大数据的实证研究,翻转课堂在教学实践中还存在一些不足。翻转课堂应该尊重学生的个性差异,合理定位教师的角色,应有完善的伦理规范,应该形成对翻转课堂的理性认识。

  2. Machine Learning and Radiology

    Science.gov (United States)

    Wang, Shijun; Summers, Ronald M.

    2012-01-01

    In this paper, we give a short introduction to machine learning and survey its applications in radiology. We focused on six categories of applications in radiology: medical image segmentation, registration, computer aided detection and diagnosis, brain function or activity analysis and neurological disease diagnosis from fMR images, content-based image retrieval systems for CT or MRI images, and text analysis of radiology reports using natural language processing (NLP) and natural language understanding (NLU). This survey shows that machine learning plays a key role in many radiology applications. Machine learning identifies complex patterns automatically and helps radiologists make intelligent decisions on radiology data such as conventional radiographs, CT, MRI, and PET images and radiology reports. In many applications, the performance of machine learning-based automatic detection and diagnosis systems has shown to be comparable to that of a well-trained and experienced radiologist. Technology development in machine learning and radiology will benefit from each other in the long run. Key contributions and common characteristics of machine learning techniques in radiology are discussed. We also discuss the problem of translating machine learning applications to the radiology clinical setting, including advantages and potential barriers. PMID:22465077

    After WTG Morton's first public demonstration in 1846 of use of ether as an anaesthetic agent, for many years anaesthesiologists did not require a machine to deliver anaesthesia to the patients. After the introduction of oxygen and nitrous oxide in the form of compressed gases in cylinders, there was a necessity for mounting these cylinders on a metal frame. This stimulated many people to attempt to construct the anaesthesia machine. HEG Boyle in the year 1917 modified the Gwathmey's machine and this became popular as Boyle anaesthesia machine. Though a lot of changes have been made for the original Boyle machine still the basic structure remains the same. All the subsequent changes which have been brought are mainly to improve the safety of the patients. Knowing the details of the basic machine will make the trainee to understand the additional improvements. It is also important for every practicing anaesthesiologist to have a thorough knowledge of the basic anaesthesia machine for safe conduct of anaesthesia.

    The purpose was to assess the diagnostic accuracy of a hand-held Doppler ultrasound (US) machine for the bedside detection of liver and vascular abnormalities after liver transplantation in the intensive care unit. The IRB approved this study, and written informed consent was obtained from all patients or the patient's legal representative. Any liver transplant recipient at our institution who needed a bedside Doppler US examination in the intensive care unit was eligible. Patients underwent routine grey-scale, colour, and spectral Doppler US examinations of the liver with a conventional machine, which was taken as the reference method, and with a hand-held machine on the same day. Examinations followed one another and were performed in a blinded fashion by two radiologists. Over a 4-month period, 24 consecutive patients (16 men, median age 54 years old; 16 cadaveric and 8 living related right liver transplantations) underwent 43 examinations with both conventional and hand-held machines. Image quality and overall satisfaction scores of grey-scale were lower with the hand-held than with the conventional machine. The hand-held was similar to the conventional machine for assessing the patency of portal veins, hepatic veins and the IVC in all patients but one. The hand-held machine failed to detect signals in the right branch of the hepatic artery and in the hilum in two and one cases, respectively. There was no abnormal hepatic arterial flow with the conventional machine in any of the patients, and the results were the same with the hand-held machine. Total examination time was significantly longer with the hand-held machine. The hand-held US machine had a high diagnostic accuracy for both parenchymal and vascular analyses compared with a conventional US machine in the bedside assessment of post-liver transplant patients.

    An increasing amount of behavioral and neurophysiological data suggests that the brain performs optimal (or near-optimal) probabilistic inference and learning during perception and other tasks. Although many machine learning algorithms exist that perform inference and learning in an optimal way, the complete description of how one of those algorithms (or a novel algorithm) can be implemented in the brain is currently incomplete. There have been many proposed solutions that address how neurons can perform optimal inference but the question of how synaptic plasticity can implement optimal learning is rarely addressed. This paper aims to unify the two fields of probabilistic inference and synaptic plasticity by using a neuronal network of realistic model spiking neurons to implement a well-studied computational model called the Helmholtz Machine. The Helmholtz Machine is amenable to neural implementation as the algorithm it uses to learn its parameters, called the wake-sleep algorithm, uses a local delta learning rule. Our spiking-neuron network implements both the delta rule and a small example of a Helmholtz machine. This neuronal network can learn an internal model of continuous-valued training data sets without supervision. The network can also perform inference on the learned internal models. We show how various biophysical features of the neural implementation constrain the parameters of the wake-sleep algorithm, such as the duration of the wake and sleep phases of learning and the minimal sample duration. We examine the deviations from optimal performance and tie them to the properties of the synaptic plasticity rule.

  14. Who Actually Sets the Criteria for Social Studies Literacy? The National Core Curricula and the Matriculation Examination as Guidelines for Social Studies Teaching in Finland in the 2000’s

    Directory of Open Access Journals (Sweden)

    Jan Löfström

    2010-12-01

    Full Text Available The issue of how to define the content of social studies literacy has become topical in Finland in the 2000’s in a new way as a result of social studies having been instituted as an independent subject in upper secondary school and in basic education. Freedom from the ties confining social studies in the role of a subdivision of the subject history has entailed a need to profile social studies and also to problematize the parametres of social studies literacy more clearly and consciously than before. However the question remains as to who defines the content of social studies literacy. In this article we will argue that in Finland today the most central role in this respect is being played not by the national core curricula where the competence aims of social studies teaching are rather vague, but by the social studies exam in the national matriculation examination. This is not necessarily a bad situation in terms of the outcome but it is noteworthy that the task of operationalizing social studies literacy is here as if “outsourced” to a small group of social science and social studies education experts who design social studies exam questions, whereas the authority responsible for developing the national core curricula only sanctions very general descriptive objectives for social studies teaching.

    Individuals with severe to profound and multiple intellectual disability (S-PMID) tend to function at the earlier stages of communication development. Variable and highly individual means of communicating may present challenges to the adults providing support in everyday life. The current study aimed to examine the communication interface between students with S-PMID and educational staff. An in-depth, observational study of dyadic interaction in a class within the secondary part of a special school was conducted. The designated educational level was Key Stage 3 under the National Curriculum of England, which is typically for children from age 11 to 14 years attending a state school. There were four student-teacher dyads in the class. The students had multiple impairments with severely limited communication skills. Video capture of dyadic interaction was conducted during five English lessons and sampled to 2.5 min per dyad per lesson. The video footage was transcribed into standard orthography, detailing the vocal and non-vocal aspects. A coding framework guided by the principles of structural-functional linguistics was used to determine the nature of dyadic interaction, comprising linguistic moves, functions and communicative modalities. The relative contributions of student and teacher to the interaction were examined. Significant differences were found between the students and educational staff on the majority of the measures. The teachers dominated the interaction, occupying significantly more turns than the students. Teacher turns contained significantly more initiations and follow-up moves than the students, who used more response moves. Teacher communication mainly served the functions of requesting and information giving. Feedback and scripted functions were also significantly greater among teacher turns, with only limited occurrence among the students. Self- or shared-expression was greatest among the students. The modalities of speech, touch, singing and

  3. About the walking machine motion stability

    Directory of Open Access Journals (Sweden)

    V. V. Lapshin

    2014-01-01

    Full Text Available The use of legs as propulsive devices of the machine will increase its capability to cross rough and deformable terrain as compared with wheeled and trucked machines. Today it is already possible to speak about design of statically stable walking robots to be used in the certain areas of application. The most promising areas of their application are exploration and emergency-rescue operations in extremely complicated situations (e.g. in the zone of destruction after earthquakes, technogenic catastrophe, etc..In such dangerous situations there is a possibility for the walking machine to be overturned either because of loosing a support to one or several legs or due to significant displacement of the leg support points, which are caused by deformation or destruction of the terrain in the points of the legs support. Therefore, it is necessary to design motion control algorithms that enable teaching the motion control system of a walking robot: How to decrease the possibility of the robot overturning? How to stop the robot as quickly as possible keeping its static stability? What must be done if static stability is lost? Note that the loss of static stability does not inevitably result in the robot falling down. How to fall down better (with minimal robot destruction in inevitable case?This work investigates the first abovementioned problems, i.e. preventing a walking machine from overturning in dangerous situations. For this purpose it suggests to use a special cautious (safe gait, which allows the machine to remain statically stable if it suddenly looses support to its any leg. The natural price for the increased safety to prevent from overturning is the reduced capabilities of robot kinematics and, as a consequence, its capability to cross rough terrain. It is also suggested to reconsider the general definition of a walking machine static stability margin in order to obtain an adequate estimation of the robot overturning possibility

    The property parameters and machining output parameters were selected for machinability evaluation of machinable ceramics. Based on fuzzy evaluation theory, two-stage fuzzy evaluation approach was applied to consider these parameters. Two-stage fuzzy comprehensive evaluation model was proposed to evaluate machinability of machinable ceramic materials. Ce-ZrO2/CePO4 composites were fabricated and machined for evaluation of machinable ceramics. Material removal rates and specific normal grinding forces were measured. The parameters concerned with machinability were selected as alternative set. Five grades were chosen for the machinability evaluation of machnable ceramics. Machinability grades of machinable ceramics were determined through fuzzy operation. Ductile marks are observed on Ce-ZrO2/CePO4 machined surface. Five prepared Ce-ZrO2/CePO4 composites are classified as three machinability grades according to the fuzzy comprehensive evaluation results. The machinability grades of Ce-ZrO2/CePO4 composites are concerned with CePO4 content.

    Directory of Open Access Journals (Sweden)

    Florian Ion Tiberiu Petrescu

    2015-09-01

    Full Text Available This paper presents the dynamic, original, machine motion equations. The equation of motion of the machine that generates angular speed of the shaft (which varies with position and rotation speed is deduced by conservation kinetic energy of the machine. An additional variation of angular speed is added by multiplying by the coefficient dynamic D (generated by the forces out of mechanism and or by the forces generated by the elasticity of the system. Kinetic energy conservation shows angular speed variation (from the shaft with inertial masses, while the dynamic coefficient introduces the variation of w with forces acting in the mechanism. Deriving the first equation of motion of the machine one can obtain the second equation of motion dynamic. From the second equation of motion of the machine it determines the angular acceleration of the shaft. It shows the distribution of the forces on the mechanism to the internal combustion heat engines. Dynamic, the velocities can be distributed in the same way as forces. Practically, in the dynamic regimes, the velocities have the same timing as the forces. Calculations should be made for an engine with a single cylinder. Originally exemplification is done for a classic distribution mechanism, and then even the module B distribution mechanism of an Otto engine type.

    2016-10-01

    Full Text Available The edition La ley del reloj. Arquitectura, máquinas y cultura moderna (Cátedra, Madrid, 2016 registers the useful paradox of the analogy between architecture and technique. Its author, the architect Eduardo Prieto, also a philosopher, professor and writer, acknowledges the obvious distance from machines to buildings, so great that it can only be solved using strange comparisons, since architecture does not move nor are the machines habitable, however throughout the book, from the origin of the metaphor of the machine, with clarity in his essay and enlightening erudition, he points out with certainty some concomitances of high interest, drawing throughout history a beautiful cartography of the fruitful encounter between organics and mechanics.

  12. Machine Learning Markets

    2011-01-01

    Prediction markets show considerable promise for developing flexible mechanisms for machine learning. Here, machine learning markets for multivariate systems are defined, and a utility-based framework is established for their analysis. This differs from the usual approach of defining static betting functions. It is shown that such markets can implement model combination methods used in machine learning, such as product of expert and mixture of expert approaches as equilibrium pricing models, by varying agent utility functions. They can also implement models composed of local potentials, and message passing methods. Prediction markets also allow for more flexible combinations, by combining multiple different utility functions. Conversely, the market mechanisms implement inference in the relevant probabilistic models. This means that market mechanism can be utilized for implementing parallelized model building and inference for probabilistic modelling.

    In August 2014, the Political Bureau of the Central Committee of the CPC held a meeting which deliberated and passed"Implementation Suggestions on Deepening the Examina-tion and Enrollment System Reform" (hereinafter referred to as"Suggestions") of Ministry of Education. It has pinpointed that the principle of"forming an examination and enrollment mode based on classified examination, comprehensive evaluation and plural-istic enrollment" should be established in the education reform. To impel the classified examination of general undergraduate ed-ucation and higher vocational education is a significant action to guide the healthy development of higher vocational and technical education. "Suggestions" also put forward the deepening of col-lege entrance examination contents, stating clearly and firmly that English teaching should return to the discipline itself, highlight and earnestly grasp the improvement of the practicality, basic knowledge and basic skills of language. This requires higher vo-cational colleges to face up to challenges, seize opportunities, transform education ideas and thoughts, establish modern out-looks on teaching and learning, and cultivate students' ability to learn English autonomously. In addition, they should also pay at-tention to the practice and application of language, adjust and optimize English curriculum system, explore college-enterprise cooperation and production-study integration, and realize the cultivation of pluralistic abilities. The aim of the above is to achieve the goal of observing education rules and returning to the essence of education in English teaching.%2014年8月,中共中央政治局召开会议,审议通过了教育部《关于深化考试招生制度改革的实施意见》(以下简称《意见》)。明确了教育改革中应建立“形成分类考试、综合评价、多元录取的考试招生模式”的原则。推进普通本科与高等职业教育分类考试,是引领高等职业技术

  16. Machining strategy choice: performance VIEWER

    Tapie, Laurent; Anselmetti, Bernard

    2009-01-01

    Nowadays high speed machining (HSM) machine tool combines productivity and part quality. So mould and die maker invested in HSM. Die and mould features are more and more complex shaped. Thus, it is difficult to choose the best machining strategy according to part shape. Geometrical analysis of machining features is not sufficient to make an optimal choice. Some research show that security, technical, functional and economical constrains must be taken into account to elaborate a machining strategy. During complex shape machining, production system limits induce feed rate decreases, thus loss of productivity, in some part areas. In this paper we propose to analyse these areas by estimating tool path quality. First we perform experiments on HSM machine tool to determine trajectory impact on machine tool behaviour. Then, we extract critical criteria and establish models of performance loss. Our work is focused on machine tool kinematical performance and numerical controller unit calculation capacity. We implement...

    Science.gov (United States)

    Chen, Guo-Hai; Watkins, David

    2010-04-01

    The relationship between teaching styles and student ratings of teaching was examined at a Chinese university. 388 teachers (170 men, 218 women) were invited to fill out the 49-item Teaching Styles Inventory (Grigorenko & Sternberg, 1993). The inventory measures seven teaching styles: legislative, judicial, liberal, global, executive, conservative, and local. Scores from students' evaluations of teaching of courses for one semester were collected. Students' evaluation scores were significantly and negatively related to executive and conservative teaching styles of their teachers, while no significant correlation was found between student ratings and any of the other five teaching styles. Only conservative teaching style contributed significantly to the prediction of student ratings. Sex and age were found to have moderating effects on the relationship between teaching style and student ratings. The role of teaching styles in student ratings was discussed.

    Current philosophy of language prides itself on scientific status. It boasts of being no longer contaminated with queer mental entities or idealist essences. It theorizes language as programmable variants of formal semantic systems, reimaginable either as the properly epiphenomenal machine functions of computer science or the properly material neural networks of physiology. Whether or not such models properly capture the physical workings of a living human brain is a question that scientists will have to answer. I, as a philosopher, come at the problem from another direction. Does contemporary philosophical semantics, in its dominant truth-theoretic and related versions, capture actual living human thought as it is experienced, or does it instead reflect, regardless of (perhaps dubious) scientific credentials, pathology of thought, a pathology with a disturbing social history.

    2004-01-01

    Biomimetics (or bionics) is the engineering discipline that constructs artificial systems using biological principles. The ideal final result in biomimetics is to create a living machine. But what are the desirable and non-desirable properties of biomimetic product? Where can natural prototypes be found? How can technical solutions be transferred from nature to technology? Can we use living nature like LEGO bricks for construction our machines? How can biology help us? What is a living machine? In biomimetic practice only some "part" (organ, part of organ, tissue) of the observed whole organism is utilized. A possible template for future super-organism extension for biomimetic methods might be drawn from experiments in holistic ecological agriculture (ecological design, permaculture, ecological engineering, etc. ). The necessary translation of these rules to practical action can be achieved with the Russian Theory of Inventive Problem Solving (TRIZ), specifically adjusted to biology. Thus, permaculture, reinforced by a TRIZ conceptual framework, might provide the basis for Super-Organismic Bionics, which is hypothesized as necessary for effective ecological engineering. This hypothesis is supported by a case study-the design of a sustainable artificial nature reserve for wild pollinators as a living machine.

    Perry, Michael D.; Stuart, Brent C.; Banks, Paul S.; Myers, Booth R.; Sefcik, Joseph A.

    2000-01-01

    The invention consists of a method for machining (cutting, drilling, sculpting) of explosives (e.g., TNT, TATB, PETN, RDX, etc.). By using pulses of a duration in the range of 5 femtoseconds to 50 picoseconds, extremely precise and rapid machining can be achieved with essentially no heat or shock affected zone. In this method, material is removed by a nonthermal mechanism. A combination of multiphoton and collisional ionization creates a critical density plasma in a time scale much shorter than electron kinetic energy is transferred to the lattice. The resulting plasma is far from thermal equilibrium. The material is in essence converted from its initial solid-state directly into a fully ionized plasma on a time scale too short for thermal equilibrium to be established with the lattice. As a result, there is negligible heat conduction beyond the region removed resulting in negligible thermal stress or shock to the material beyond a few microns from the laser machined surface. Hydrodynamic expansion of the plasma eliminates the need for any ancillary techniques to remove material and produces extremely high quality machined surfaces. There is no detonation or deflagration of the explosive in the process and the material which is removed is rendered inert.

    2015-09-01

    Full Text Available This paper examines how religious concepts both reflected and informed the development of new technologies for encoding, transmitting, and printing written information. While many spiritualist writing machines were based on existing technologies that were repurposed for spirit communication, others prefigured or even inspired more advanced technological innovations. The history of spiritualist writing machines thus not only represents a response to the rise of new media technologies in the nineteenth century, but it also reflects a set of cultural demands that helped to shape the development of new technologies, such as the need to replace handwriting with discrete, uniform lettering, which accelerated the speed of composition; the need to translate written information into codes, which could be transmitted across vast distances; and the need to automate the process of transmitting, translating, and transcribing written information, which seemed to endow the machines themselves with a certain degree of autonomy or even intelligence. While spiritualists and inventors were often (but not always motivated by different goals, the development of spiritualist writing machines and the development of technological writing machines were nevertheless deeply interrelated and interdependent.

    Full Text Available In her conceptualization of the human as defined by the capacity for revolt Kristeva unavoidably touches upon issues of robotization, technology, and the virtual. The concepts of animal and machine, however, although they do appear occasionally and in important ways, are never at the focus of her inquiries and are absent in her “New Forms of Revolt.” Yet these two concepts to a large extent define the field of contemporary philosophical debates of the human giving rise to three major theoretical orientations. On the one hand, there is the trend which tries to come to terms with technological novelties and the merging of human and machine that they imply. This trend unfolds under the rubric of “transhuman” or “posthuman” and of the “enhancement” of man. The second trend predominates in animal studies. Mostly in an ethical perspective but also ontologically, this trend, to which Derrida’s later writing made a significant contribution, questions the idea of the “human exception” and the rigorous distinction between man and animal on which this exception rests. While apparently antagonistic, both trends align the human with the animal and oppose it to technology. The third trend collapses the distinctions on which the previous two rely through the lens of biopolitics: drawing on Heidegger, Kojève, and Foucault, it regards contemporary technological transformations as amounting to the animalization of man.  The human disappears in the animal, in the machine, or in the indistinguishability of the two, confirming what Agamben has described as the inoperativeness of the anthropological machine. The present text turns to Kristeva’s conceptions of motherhood and revolt as introducing a powerful inflection in this tripartite field. Remarkably, it is precisely new sagas of rebellious machines like Battlestar “Galactica” that foreground the relevance of Kristeva’s approach.

    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.

  20. A Boltzmann machine for the organization of intelligent machines

    Moed, Michael C.; Saridis, George N.

    1989-01-01

    In the present technological society, there is a major need to build machines that would execute intelligent tasks operating in uncertain environments with minimum interaction with a human operator. Although some designers have built smart robots, utilizing heuristic ideas, there is no systematic approach to design such machines in an engineering manner. Recently, cross-disciplinary research from the fields of computers, systems AI and information theory has served to set the foundations of the emerging area of the design of intelligent machines. Since 1977 Saridis has been developing an approach, defined as Hierarchical Intelligent Control, designed to organize, coordinate and execute anthropomorphic tasks by a machine with minimum interaction with a human operator. This approach utilizes analytical (probabilistic) models to describe and control the various functions of the intelligent machine structured by the intuitively defined principle of Increasing Precision with Decreasing Intelligence (IPDI) (Saridis 1979). This principle, even though resembles the managerial structure of organizational systems (Levis 1988), has been derived on an analytic basis by Saridis (1988). The purpose is to derive analytically a Boltzmann machine suitable for optimal connection of nodes in a neural net (Fahlman, Hinton, Sejnowski, 1985). Then this machine will serve to search for the optimal design of the organization level of an intelligent machine. In order to accomplish this, some mathematical theory of the intelligent machines will be first outlined. Then some definitions of the variables associated with the principle, like machine intelligence, machine knowledge, and precision will be made (Saridis, Valavanis 1988). Then a procedure to establish the Boltzmann machine on an analytic basis will be presented and illustrated by an example in designing the organization level of an Intelligent Machine. A new search technique, the Modified Genetic Algorithm, is presented and proved

    Biological molecular motors use chemical energy, mostly in the form of ATP hydrolysis, and convert it to mechanical energy. Correlated thermal fluctuations are essential for the function of a molecular machine and it is the hydrolysis of ATP that modifies the correlated fluctuations of the system. Correlations are consequences of the molecular architecture of the protein. The idea that synthetic molecular machines may be constructed by designing the proper molecular architecture is challenging. In their paper, Sarkar et al (2016 New J. Phys. 18 043006) propose a synthetic molecular motor based on the coarse grained elastic network model of proteins and show by numerical simulations that motor function is realized, ranging from deterministic to thermal, depending on temperature. This work opens up a new range of possibilities of molecular architecture based engine design.

    Full Text Available Artificial Intelligence (AI is a branch of computer science concerned with making computers behave like humans. At least this was the original idea. However, it turned out that this is no task easy to be solved. This article aims to give a comprehensible review on the last 60 years of artificial intelligence taking a philosophical viewpoint. It is outlined what happened so far in AI, what is currently going on in this research area, and what can be expected in future. The goal is to mediate an understanding for the developments and changes in thinking in course of time about how to achieve machine intelligence. The clear message is that AI has to join forces with neuroscience and other brain disciplines in order to make a step towards the development of truly intelligent machines.

    Protection of accelerator equipment is as old as accelerator technology and was for many years related to high-power equipment. Examples are the protection of powering equipment from overheating (magnets, power converters, high-current cables), of superconducting magnets from damage after a quench and of klystrons. The protection of equipment from beam accidents is more recent, although there was one paper that discussed beam-induced damage for the SLAC linac (Stanford Linear Accelerator Center) as early as in 1967. It is related to the increasing beam power of high-power proton accelerators, to the emission of synchrotron light by electron-positron accelerators and to the increase of energy stored in the beam. Designing a machine protection system requires an excellent understanding of accelerator physics and operation to anticipate possible failures that could lead to damage. Machine protection includes beam and equipment monitoring, a system to safely stop beam operation (e.g. dumping the beam or stopping ...

    2006-01-01

    The term ‘profile machining’is used to refer to the milling of vertical surfaces described by profile curves. Profile machining requires higher precision (1/1000 mm) than regular 3D machining (1/100 mm) with the erosion of sharp vertices should being especially avoided. Although, profile machining is very essential for making trimming and flangedies, it seldom brought into focus. This paper addresses the technological requirements of profile machining including machining width and depth control,minimizing toolware, and protecting sharp vertices. Issues of controller alarms are also addressed.

    Compared to high tool wear and high costs of tooling of fiber-reinforced composites (FRCs), noncontact material-removal processes offer attractive alternative. Noncontact machining methods can also minimize dust, noise, and extensive plastic deformation and consequent heat generation associated with conventional machining of FRCs, espacially those with an epoxy matrix. The paper describes the principles involved in and the details of machining of FRCs by laser machining, water jet-cutting and abrasive water jet-cutting, and electrical discharge machining of composites, as well as the limitations of each method.

    Full Text Available Electrochemical discharge machining process is evolving as a promising micromachiningprocess. The experimental investigations in the present work substantiate this trend. In the presentwork, in situ, synchronised, transient temperature and current measurements have been carriedout. The need for the transient measurements arose due to the time-varying nature of the dischargeformation and time varying circuit current. Synchronised and transient measurements revealedthe discrete nature of the process. It also helped in formulating the basic mechanism for thedischarge formation and the material removal in the process. Temperature profile on workpieceand in electrochemical discharge machining cell is experimentally measured using pyrometer,and two varieties of K-type thermocouples. Surface topography of the discharge-affected zoneson the workpiece has been carried out using scanning electron microscope. Measurements andsurface topographical studies reveal the potential use of this process for machining in micronregime. With careful experimental set-up design, suitable supply voltage and its polarity, theprocess can be applied for both micromachining and micro-deposition. It can be extended formachining and or deposition of wide range of materials.

    Full Text Available This issue of 19 brings together a selection of essays from an interdisciplinary conference on 'Minds, Bodies, Machines' convened last year by Birkbeck's Centre for Nineteenth-Century Studies, University of London, in partnership with the English programme, University of Melbourne and software developers Constraint Technologies International (CTI. The conference explored the relationship between minds, bodies and machines in the long nineteenth century, with a view to understanding the history of our technology-driven, post-human visions. It is in the nineteenth century that the relationship between the human and the machine under post-industrial capitalism becomes a pervasive theme. From Blake on the mills of the mind by which we are enslaved, to Carlyle's and Arnold's denunciation of the machinery of modern life, from Dickens's sooty fictional locomotive Mr Pancks, who 'snorted and sniffed and puffed and blew, like a little labouring steam-engine', and 'shot out […]cinders of principles, as if it were done by mechanical revolvency', to the alienated historical body of the late-nineteenth-century factory worker under Taylorization, whose movements and gestures were timed, regulated and rationalised to maximize efficiency; we find a cultural preoccupation with the mechanisation of the nineteenth-century human body that uncannily resonates with modern dreams and anxieties around technologies of the human.

    Spurred by advances in processing power, memory, storage, and an unprecedented wealth of data, computers are being asked to tackle increasingly complex learning tasks, often with astonishing success. Computers have now mastered a popular variant of poker, learned the laws of physics from experimental data, and become experts in video games - tasks that would have been deemed impossible not too long ago. In parallel, the number of companies centered on applying complex data analysis to varying industries has exploded, and it is thus unsurprising that some analytic companies are turning attention to problems in health care. The purpose of this review is to explore what problems in medicine might benefit from such learning approaches and use examples from the literature to introduce basic concepts in machine learning. It is important to note that seemingly large enough medical data sets and adequate learning algorithms have been available for many decades, and yet, although there are thousands of papers applying machine learning algorithms to medical data, very few have contributed meaningfully to clinical care. This lack of impact stands in stark contrast to the enormous relevance of machine learning to many other industries. Thus, part of my effort will be to identify what obstacles there may be to changing the practice of medicine through statistical learning approaches, and discuss how these might be overcome.

However, existing work has not been conclusive on the contribution of visual information. This paper presents an in-depth study of the problem by examining the differences and complementarities of two related but distinct approaches to this task: textonly neural machine translation and image captioning. We analyse the scope for improvement and the effect of different data and settings to build models for these tasks. We also propose ways of combining these two approaches for improved translation quality.

    Full Text Available Enhancing the overall machining performance implies optimization of machining processes, i.e. determination of optimal machining parameters combination. Optimization of machining processes is an active field of research where different optimization methods are being used to determine an optimal combination of different machining parameters. In this paper, multi-stage Monte Carlo (MC method was employed to determine optimal combinations of machining parameters for six machining processes, i.e. drilling, turning, turn-milling, abrasive waterjet machining, electrochemical discharge machining and electrochemical micromachining. Optimization solutions obtained by using multi-stage MC method were compared with the optimization solutions of past researchers obtained by using meta-heuristic optimization methods, e.g. genetic algorithm, simulated annealing algorithm, artificial bee colony algorithm and teaching learning based optimization algorithm. The obtained results prove the applicability and suitability of the multi-stage MC method for solving machining optimization problems with up to four independent variables. Specific features, merits and drawbacks of the MC method were also discussed.

  7. Mineral mining machines

    Energy Technology Data Exchange (ETDEWEB)

    Mc Gaw, B.H.

    1984-01-01

    A machine for mining minerals is patented. It is a cutter loader with a drum actuating element of the worm type equipped with a multitude of cutting teeth reinforced with tungsten carbide. A feature of the patented machine is that all of the cutting teeth and holders on the drum have the identical design. This is achieved through selecting a slant angle for the cutting teeth which is the mean between the slant angle of the conventional radial teeth and the slant angle of the advance teeth. This, in turn, is provided thanks to the corresponding slant of the holders relative to the drum and (or) the slant of the cutting part of the teeth relative to their stems. Thus, the advance teeth projecting beyond the surface of the drum on the face side and providing upper and lateral clearances have the same angle of attack as the radial teeth, that is, from 20 to 35 degrees. A series of modifications of the cutting teeth is patented. One of the designs allows the cutting tooth to occupy a varying position relative to the drum, from the conventional vertical to an inverted, axially projecting position. In the last case the tooth in the extraction process provides the upper and lateral clearances for the drum on the face side. Among the different modifications of the cutting teeth, a design is proposed which provides for the presence of a stem which is shaped like a truncated cone. This particular stem is designed for use jointly with a wedge which unfastens the teeth and is placed in a holder. The latter is completed in a transverse slot thanks to which the rear end of the stem is compressed, which simplifies replacement of a tooth. Channels are provided in the patented machine for feeding water to the worm spiral, the holders and the cutting teeth themselves in order to deal with dust.

    The present paper tries to evaluate the applicability of conventional sound analysis techniques and modern machine learning algorithms to rotating machine health monitoring. These techniques include support vector machine, deep leaning neural network, etc. The inner ring defect and misalignment anomaly sound data measured by a rotating machine mockup test facility are used to verify the above various kinds of algorithms. Although we cannot find remarkable difference of anomaly discrimination performance, some methods give us the very interesting eigen patterns corresponding to normal and abnormal states. These results will be useful for future more sensitive and robust anomaly monitoring technology.

    Full Text Available This article is targeted to faculty teaching race and ethnicity, racism, diversity, and multicultural courses. Many students equate race with skin color. The premise of this article is that to teach students about the social construction of race, teachers must first know enough science to teach students that race is not biological. This article examines the biology of race by showing how advances in DNA sequencing led to genetics research that supports arguments that race is not biological. DNA comparisons show that all human populations living today are one species that came from Africa. The article explains the migration of humans out of Africa about 60,000 years ago and how they populated Australia, then Asia, Europe, and the Americas. The article shows how recent research maps the timing of the migration and admixture of specific population groups into Europe and India. The article shows how a mutation in one nucleotide can result in a trait like blue eyes, or Hemoglobin S (which confers resistance to malaria, which can be subject to evolution through natural selection. DNA comparisons show how natural selection shaped the genetics of human skin color to adapt to less UV light in the northern latitudes of Europe and Asia. The article shows that there is no relation between skin color or other “racial” characteristics and complex traits like intelligence. The science in this article will help teachers explain that as race is not biological, race is socially constructed and culturally enacted.

    2000-01-27

    The fundamental goal of this project was to develop additional capabilities to the diamond measuring prototype, work out technical difficulties associated with the original device, and perform automated measurements which are accurate and repeatable. For this project, FM and T was responsible for the overall system design, edge extraction, and defect extraction and identification. AccuGem provided a lab and computer equipment in Lawrence, 3D modeling, industry expertise, and sets of diamonds for testing. The system executive software which controls stone positioning, lighting, focusing, report generation, and data acquisition was written in Microsoft Visual Basic 6, while data analysis and modeling were compiled in C/C++ DLLs. All scanning parameters and extracted data are stored in a central database and available for automated analysis and reporting. The Phase 1 study showed that data can be extracted and measured from diamond scans, but most of the information had to be manually extracted. In this Phase 2 project, all data required for geometric modeling and defect identification were automatically extracted and passed to a 3D modeling module for analysis. Algorithms were developed which automatically adjusted both light levels and stone focus positioning for each diamond-under-test. After a diamond is analyzed and measurements are completed, a report is printed for the customer which shows carat weight, summarizes stone geometry information, lists defects and their size, displays a picture of the diamond, and shows a plot of defects on a top view drawing of the stone. Initial emphasis of defect extraction was on identification of feathers, pinpoints, and crystals. Defects were plotted color-coded by industry standards for inclusions (red), blemishes (green), and unknown defects (blue). Diamonds with a wide variety of cut quality, size, and number of defects were tested in the machine. Edge extraction, defect extraction, and modeling code were tested for

    We develop an approach to machine learning and anomaly detection via quantum adiabatic evolution. In the training phase we identify an optimal set of weak classifiers, to form a single strong classifier. In the testing phase we adiabatically evolve one or more strong classifiers on a superposition of inputs in order to find certain anomalous elements in the classification space. Both the training and testing phases are executed via quantum adiabatic evolution. We apply and illustrate this approach in detail to the problem of software verification and validation.

    Daphne, a high luminosity e{sup +}/e{sup -} {Phi} factory, is presently under construction in Frascati. The beginning of the collider commissioning is scheduled by winter 1997, with a short term luminosity goal L=1.3 10{sup 32} cm{sup -2} sec{sup -1}. Daphne shall be the first of the new generation of very high luminosity colliders, called factories, to come in operation. Other factories under construction are PEP-II and KEK-B: first collision, for both machines, is planned for 1998.

    A device is described that is specifically designed to cast uraniumn fuel rods in a vacuunn, in order to obtain flawless, nonoxidized castings which subsequently require a maximum of machining or wastage of the expensive processed material. A chamber surrounded with heating elements is connected to the molds, and the entire apparatus is housed in an airtight container. A charge of uranium is placed in the chamber, heated, then is allowed to flow into the molds While being rotated. Water circulating through passages in the molds chills the casting to form a fine grained fuel rod in nearly finished form.

  16. Using Machine Learning to Search for MSSM Higgs Bosons

    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.

  17. Machining of Complex Sculptured Surfaces

    2012-01-01

    The machining of complex sculptured surfaces is a global technological topic in modern manufacturing with relevance in both industrialized and emerging in countries particularly within the moulds and dies sector whose applications include highly technological industries such as the automotive and aircraft industry. Machining of Complex Sculptured Surfaces considers new approaches to the manufacture of moulds and dies within these industries. The traditional technology employed in the manufacture of moulds and dies combined conventional milling and electro-discharge machining (EDM) but this has been replaced with  high-speed milling (HSM) which has been applied in roughing, semi-finishing and finishing of moulds and dies with great success. Machining of Complex Sculptured Surfaces provides recent information on machining of complex sculptured surfaces including modern CAM systems and process planning for three and five axis machining as well as explanations of the advantages of HSM over traditional methods ra...

    A Boltzmann machine is a stochastic neural network that has been extensively used in the layers of deep architectures for modern machine learning applications. In this paper, we develop a Boltzmann machine that is capable of modeling thermodynamic observables for physical systems in thermal equilibrium. Through unsupervised learning, we train the Boltzmann machine on data sets constructed with spin configurations importance sampled from the partition function of an Ising Hamiltonian at different temperatures using Monte Carlo (MC) methods. The trained Boltzmann machine is then used to generate spin states, for which we compare thermodynamic observables to those computed by direct MC sampling. We demonstrate that the Boltzmann machine can faithfully reproduce the observables of the physical system. Further, we observe that the number of neurons required to obtain accurate results increases as the system is brought close to criticality.

  20. Cytogenetic examination

    OpenAIRE

    2015-01-01

    Cytogenetic examination on six normal persons, four men and two women, was carried out using a technique proposed by Dutrillaux with slight modification. Five drops of blood were taken from a peripheral vessel and was incubated on a PHA (phytohemarglutinine)-containing medium at 37°C for about 72 hours. Cell division was blocked by adding colchicine solution, an antimitotic agent, into this medium. A mixture of distilled water, magnesium chloride, hyaluronidase, and goat serum was used as hy...
