    Full Text Available Abstract Background Previous studies have identified brain areas related to cognitive abilities and personality, respectively. In this exploratory study, we extend the application of modern neuroimaging techniques to another area of individual differences, vocational interests, and relate the results to an earlier study of cognitive abilities salient for vocations. Findings First, we examined the psychometric relationships between vocational interests and abilities in a large sample. The primary relationships between those domains were between Investigative (scientific interests and general intelligence and between Realistic (“blue-collar” interests and spatial ability. Then, using MRI and voxel-based morphometry, we investigated the relationships between regional gray matter volume and vocational interests. Specific clusters of gray matter were found to be correlated with Investigative and Realistic interests. Overlap analyses indicated some common brain areas between the correlates of Investigative interests and general intelligence and between the correlates of Realistic interests and spatial ability. Conclusions Two of six vocational-interest scales show substantial relationships with regional gray matter volume. The overlap between the brain correlates of these scales and cognitive-ability factors suggest there are relationships between individual differences in brain structure and vocations.

    Adachi, Tomoko

    2004-08-01

    The Social Cognitive Career Model proposes that career interests arise from beliefs about capability to execute a course of activity (self-efficacy), and beliefs about the consequences of performing particular activities (outcome expectations). In our study, 301 Japanese university students were given questionnaires including the Vocational Preference Inventory and scales assessing Career Self-efficacy and Career-outcome Expectations. Hierarchical multiple regression analyses indicated both self-efficacy and outcome expectations were significantly related to vocational interests. Outcome expectations accounted for significant incremental variance in explaining interests across six of Holland's vocational environments. Implications of social cognitive theory for career development and interventions among Japanese university students are discussed.

  11. Vocational Interests and Performance: A Quantitative Summary of Over 60 Years of Research.

    2012-07-01

    Despite early claims that vocational interests could be used to distinguish successful workers and superior students from their peers, interest measures are generally ignored in the employee selection literature. Nevertheless, theoretical descriptions of vocational interests from vocational and educational psychology have proposed that interest constructs should be related to performance and persistence in work and academic settings. Moreover, on the basis of Holland's (1959, 1997) theoretical predictions, congruence indices, which quantify the degree of similarity or person-environment fit between individuals and their occupations, should be more strongly related to performance than interest scores alone. Using a comprehensive review of the interest literature that spans more than 60 years of research, a meta-analysis was conducted to examine the veracity of these claims. A literature search identified 60 studies and approximately 568 correlations that addressed the relationship between interests and performance. Results showed that interests are indeed related to performance and persistence in work and academic contexts. In addition, the correlations between congruence indices and performance were stronger than for interest scores alone. Thus, consistent with interest theory, the fit between individuals and their environment was more predictive of performance than interest alone.

  12. Vocational interests and career indecision among psychosis-prone college students.

    Poreh, A M; Schullen, C

    1998-10-01

    This study investigated the relationship between scores on scales that purport to measure psychosis-proneness and scores on vocational interests, identity, and differentiation scales in a sample of 233 college students who completed the Perceptual Aberration and Magical Ideation scales, the Strong Campbell Interest Inventory, and the Career Decision Scale. The present findings are consistent with prior work indicating a sex-related association of scores on measures of psychosis-proneness and vocational interests. A positive correlation between scores on vocational indecision and measures of psychosis-proneness was also found, suggesting that both men and women who score high on psychosis-proneness find it difficult to formulate long-term career goals. Finally, there was no significant correlation between scores on measures of psychosis-proneness and Holland's Vocational Differentiation Index. Present results are discussed in light of previously reported sex differences among psychosis-prone adults and diagnosed schizophrenics. The implications of the findings for vocational counselors are also addressed.

    RENÉ T. PROYER

    2006-12-01

    Full Text Available The aim of this study was to further explore the relationship between vocational interests and intelligence. There is some evidence in literature on the stable relationships between vocational interests and intelligence (cf. Ackerman & Heggestad, 1997. It should be noted that the majority of the previous studies have only used questionnaires for the assessment of vocational interests. Thus, it is of interest whether the results are also stable when different assessment methods are used. Therefore, a nonverbal test was used in this study together with two questionnaires. Additionally, tests for general intelligence, verbal, numeric, and spatial ability, and memory were used. A sample of N = 138 persons was tested in a computerized setting. Results indicate that there is a positive relation between Realistic and Investigative interests and spatial ability. This result was found for both the questionnaires as well as the nonverbal test. Therefore, it can be assumed that this relation is stable for different assessment methods. The data is discussed with respect to current literature.

    Situational Judgement Tests (SJTs) are increasingly implemented in medical school admissions. In this paper, we investigate the effects of vocational interests, previous academic experience, gender and age on SJT performance. The SJT was part of the selection process for the Bachelor's degree programme in Medicine at University of Groningen, the Netherlands. All applicants for the academic year 2015-2016 were included and had to choose between learning communities Global Health (n = 126), Sustainable Care (n = 149), Intramural Care (n = 225), or Molecular Medicine (n = 116). This choice was used as a proxy for vocational interest. In addition, all graduate-entry applicants for academic year 2015-2016 (n = 213) were included to examine the effect of previous academic experience on performance. We used MANCOVA analyses with Bonferroni post hoc multiple comparisons tests for applicant performance on a six-scenario SJT. The MANCOVA analyses showed that for all scenarios, the independent variables were significantly related to performance (Pillai's Trace: 0.02-0.47, p < .01). Vocational interest was related to performance on three scenarios (p < .01). Graduate-entry applicants outperformed all other groups on three scenarios (p < .01) and at least one other group on the other three scenarios (p < .01). Female applicants outperformed male applicants on three scenarios (p < .01) and age was positively related to performance on two scenarios (p < .05). A good fit between applicants' vocational interests and SJT scenario was related to better performance, as was previous academic experience. Gender and age were related to performance on SJT scenarios in different settings. Especially the first effect might be helpful in selecting appropriate candidates for areas of health care in which more professionals are needed.

    One of the major topics for the introduction of extreme ultraviolet (EUV) technology is the availability of defect-free masks. From the mask makers' perspective, the quality of the incoming blank material is one of the key ingredients impacting the yield of structured masks. Besides flatness and layer thickness uniformity, the number of defects determines the final quality of the mask delivered to the customer for printing. Defects within the layers of optical blanks have shown that they have a growing impact on the mask structuring process, well below the usual defect specifications of the blanks. It is expected that this finding will also hold true for material layers above the multi-layer. In addition to printing performance, EUV masks need to have a defect-free multi-layer. While this layer is easily accessible during blank production, mask makers usually acquire the complete blank stacks with or without the coated resist. Incoming blank inspection, therefore, must check the quality of the complete stack without destroying any of the functionality of these layers. Siemens and AMTC have jointly developed a blank inspection tool that has been installed in AMTC's Dresden facility and that allows the screening of an EUV blank under these boundary conditions. Previously, SEMATECH successfully installed an M7360 from Lasertec in its Mask Blank Development Center (MBDC) in Albany, NY, that shows much better sensitivity data than SEMATECH's earlier tool, the Lasertec M1350. This paper describes the early performance of the Siemens DF-40XP on programmed multi-layer defect blanks and regular blanks and compares it to that of the existing tools at the SEMATECH MBDC.

    Full Text Available The main aim of this study was to evaluate the usefulness of different techniques for the assessment of vocational interests. In an empirical study (n = 264 a questionnaire, a nonverbal test, several objective personality tests, and a semi-projective test were applied in one single session in a computerized setting. All tests enable the assessment of vocational interests with regard to the theory of vocational interests by Holland (1997. Results showed that highest correlations to a Holland-type questionnaire were found for the questionnaire and the nonverbal test. In general, the objective personality tests were less homogenous and showed lower correlations to questionnaires. Nevertheless, all different measures showed potential for the assessment of vocational interests. Improvements in the test material and scoring methods of the newly constructed tests are discussed and a model for the combined use of different assessment methods is presented. Future research directions and a discussion on the role of a multimethod assessment strategy in practice are given.

    Full Text Available Choosing a profession is complex and often affects many areas of one’s future life. In a representative study we analyzed data of 4,447 German adolescents, aged seventeen, who were interviewed in the years between 2000 and 2013. The aim of the study was to identify the effects of gender, school type, personality and leisure activities on vocational expectations and career-choice stages of generation Y. Especially, it was of interest which effect remained as a generational time effect after controlling for the named variables. For the analysis we used descriptive statistics with rank orders and mean values as well as linear and logistic regression analyses. Engagement in different leisure activities, gender and form of education all greatly affect the perceived importance of profession characteristics. While young women and students from German grammar schools rank “stimulating tasks” first, young men and students from all other school forms feel that a “secure position” is the most important. Also, personality factors influence the perceived importance of vocational features, with agreeable and extravert adolescents rating “contact to others”, “importance to society”, “helping others” and similar features significantly higher. After controlling for the named variables, there remained a significant correlation between the survey year and the term “secure position” which became less important, and the terms “working conditions”, “importance for society” and “helping others” all three of which became more important. A trend towards a higher valuation of one’s individual social responsibility can thus be noticed.

    Blank firing weapons are designed only for discharging blank ammunition cartridges. Because they are cost-effective, are easily accessible and can be modified to live firearms plus their unclear legal situation in Turkish Law makes them very popular in Turkey. 2004 through 2008, a total of 1115 modified blank weapons were seized in Turkey. Blank firing weapons are easily modified by owners, making them suitable for discharging live firearm ammunition or modified blank ammunitions. Two common methods are used for modification of blank weapons. After the modification, these weapons can discharge the live ammunition. However, due to compositional durability problems with these types of weapons; the main trend is to use the modified blank ammunitions rather than live firearm ammunition fired from modified blank firing weapons. In this study, two types of modified blank weapons and two types of modified blank cartridges were tested on three different target models. Each of the models' shooting side was coated with 1.3+/-2 mm thickness chrome tanned cowhide as a skin simulant. The first model was only coated with skin simulant. The second model was coated with skin simulant and 100% cotton police shirt. The third model was coated with skin simulant and jean denim. After the literature evaluation four high risky anatomic locations (the neck area; the eyes; the thorax area and inguinal area) were pointed out for the steel and lead projectiles are discharged from the modified blank weapons especially in close range (0-50 cm). The target models were designed for these anatomic locations. For the target models six Transparent Ballistic Candle blocks (TCB) were prepared and divided into two test groups. The first group tests were performed with lead projectiles and second group with steel projectile. The shortest penetration depth (lead projectile: 4.358 cm; steel projectile 8.032 cm) was recorded in the skin simulant and jean denim coated block for both groups. In both groups

    2011-01-01

    Many countries belonging to the Organisation for Economic Co-operation and Development (OECD) note a shortage of highly qualified scientific-technical personnel, whereas demand for such employees is growing. Therefore, how to motivate (female) high performers in science or mathematics to pursue scientific careers is of special interest. The sample for this study is taken from the Programme for International Student Assessment (PISA) 2006. It comprises 7,819 high performers either in sciences or mathematics from representative countries of four different education systems which generally performed well or around the OECD average in PISA 2006: Switzerland, Finland, Australia, and Korea. The results give evidence that gender specificity and gender inequity in science education are a cross-national problem. Interests in specific science disciplines only partly support vocational choices in scientific-technical fields. Instead, gender and gender stereotypes play a significant role. Enhancing the utility of a scientific vocational choice is expected to soften the gender impact.

    Full Text Available The aim of this study was to validate Holland’s hexagonal and Tracey’s spherical model of vocational interests in young adults in Serbia and Bulgaria. To this end, 1250 participants, 560 from Serbia and 690 from Bulgaria, filled in Serbian and Bulgarian versions of the Personal Globe Inventory (PGI, Tracey, 2002. Hubert and Arabie’s randomization test of hypothetical orders, multidimensional scaling with fixed coordinates, Myors test and exploratory factor analysis were used. The results showed that the hexagonal and spherical models well explained the structure of vocational interests in both samples. The level of fit of the hexagonal model to the data obtained by using the PGI was generally higher than those established in the studies that used other Holland-based instruments. Furthermore, the levels of fit of both hexagonal and spherical model were in the same range like those obtained in previous studies in other countries. The results also pointed out a remarkable similarity in the structure of vocational interests in the Bulgarian and Serbian samples. [Projekat Ministarstva nauke Republike Srbije, br. 179002

    Vocational interests are important aspects of personality that reflect individual differences in motives, goals, and personal strivings. It is therefore plausible that these characteristics have an impact on individuals' lives not only in terms of vocational outcomes, but also beyond the vocational domain. Yet the effects of vocational interests on various life outcomes have rarely been investigated. Using Holland's RIASEC taxonomy (Holland, 1997), which groups vocational interests into 6 broad domains, the present study examined whether vocational interests are significant predictors of life outcomes that show incremental validity over and above the Big Five personality traits. For this purpose, a cohort of German high school students (N = 3,023) was tracked over a period of 10 years after graduating from school. Linear and logistic regression analyses were used to examine the predictive validity of RIASEC interests and Big Five personality traits. Nine outcomes from the domains of work, relationships, and health were investigated. The results indicate that vocational interests are important predictors of life outcomes that show incremental validity over the Big Five personality traits. Vocational interests were significant predictors of 7 of the 9 investigated outcomes: full-time employment, gross income, unemployment, being married, having children, never having had a relationship, and perceived health status. For work and relationship outcomes, vocational interests were even stronger predictors than the Big Five personality traits. For health-related outcomes, the results favored the personality traits. Effects were similar across gender for all outcomes-except 2 relationship outcomes. Possible explanations for these effects are discussed.

  18. Mask Blank Defect Detection

    Energy Technology Data Exchange (ETDEWEB)

    Johnson, M A; Sommargren, G E

    2000-02-04

    Mask blanks are the substrates that hold the master patterns for integrated circuits. Integrated circuits are semiconductor devices, such as microprocessors (mPs), dynamic random access memory (DRAMs), and application specific integrated circuits (ASICs) that are central to the computer, communication, and electronics industries. These devices are fabricated using a set of master patterns that are sequentially imaged onto light-sensitive coated silicon wafers and processed to form thin layers of insulating and conductive materials on top of the wafer. These materials form electrical paths and transistors that control the flow of electricity through the device. For the past forty years the semiconductor industry has made phenomenal improvements in device functionality, compactness, speed, power, and cost. This progress is principally due to the exponential decrease in the minimum feature size of integrated circuits, which has been reduced by a factor of {radical}2 every three years. Since 1992 the Semiconductor Industry Association (SIA) has coordinated the efforts of producing a technology roadmap for semiconductors. In the latest document, ''The International Technology Roadmap for Semiconductors: 1999'', future technology nodes (minimum feature sizes) and targeted dates were specified and are summarized in Table 1. Lithography is the imaging technology for producing a de-magnified image of the mask on the wafer. A typical de-magnification factor is 4. Mask blank defects as small as one-eighth the equivalent minimum feature size are printable and may cause device failure. Defects might be the result of the surface preparation, such as polishing, or contamination due to handling or the environment. Table 2 shows the maximum tolerable defect sizes on the mask blank for each technology node. This downward trend puts a tremendous burden on mask fabrication, particularly in the area of defect detection and reduction. A new infrastructure for mask

  1. Stability of vocational interests among the intellectually gifted from adolescence to adulthood: a 15-year longitudinal study.

    Lubinski, D; Benbow, C P; Ryan, J

    1995-02-01

    A sample of 162 intellectually gifted adolescents (top 1%) were administered the Strong-Campbell Interest Inventory at age 13. Fifteen years later, they were administered the Strong again. This study evaluated the intra- and interindividual temporal stability of the 6 RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) themes and the Strong's 23 Basic Interest Scales. Over the 15-year test-retest interval, RIASEC's median interindividual correlation for the 6 themes was .46; the median of all 162 intraindividual correlations was .57. Configural analyses of the most dominant theme at age 13 revealed that this theme was significantly more likely than chance to be either dominant or adjacent to the dominant theme at age 28--following RIASEC's hexagonal structure. For intellectually gifted individuals, it appears to be possible to forecast salient features of their adult RIASEC profile by assessing their vocational interests during early adolescence, but some RIASEC themes seem more stable than others.

    Full Text Available Vocational interests can be defined as standards of preference, aversion or indifference to professional activities, but little is known about the factors involved in their development. From this perspective, this study attempted to clarify which variable, age or schooling, better fit comparisons of profile differentiation index. To this end, we analyzed the Escala de Aconselhamento Profissional (Professional Counseling Scale responses of 6,824 Brazilian students between 14 and 50 years old with various levels of education. Differentiation of the interest profile was observed by subtraction between dimensions with lower and higher scores. Normality of the distributions was verified and then Analysis of Variance and Tukey’s post hoc test were conducted in relation to groups of age and schooling. The results suggest that schooling is a more appropriate variable to compare the differentiation of interests. The implications and limitations of this study are discussed, and suggestions for future studies are given.

    In 3 studies (respective Ns = 289, 394, and 1,678), males and females were assessed on Big Five traits, masculine instrumentality (M), feminine expressiveness (F), gender diagnosticity (GD), and RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) vocational interest scales. Factor analyses of RIASEC scores consistently showed evidence for D.J. Prediger's (1982) People-Things and Ideas-Data dimensions, and participants' factor scores on these dimensions were computed. In all studies Big Five Openness was related to Ideas-Data but not to People-Things. Gender was strongly related to People-Things but not to Ideas-Data. Within each sex, GD correlated strongly with People-Things but not with Ideas-Data. M, F, and Big Five measures other than Openness tended not to correlate strongly with RIASEC scales or dimensions. The results suggest that gender and gender-related individual differences within the sexes are strongly linked to the People-Things dimension of vocational interests.

    In some cultures, individuals are free to pursue careers that match their personalities. In others, familial and societal expectations regarding career paths may restrict the links between individual personality and interests. Gender role expectations also may vary across cultures and may be associated with gender differences in interests. Past meta-analytic research has shown some career interests are related to personality traits (Barrick, Mount, & Gupta, 2003; Larson, Rottinghaus, & Borgen, 2002), but the cross-cultural variation of these relationships has not been sufficiently explored. Interest and personality data were obtained from an archival data set of 391,485 individuals from 20 countries. Results indicated that in cultures with high in-group collectivism, connections between personality traits and occupational interests may be less pronounced. Cultural gender egalitarianism moderated the level of gender differences in interests, unexpectedly demonstrating that gender differences may be wider in egalitarian cultures. Implications for career guidance in multicultural settings are discussed.

    Full Text Available Strategy Europe 2020 aims to ensure an economic growth: smart, more efficient throught investment in education, reseatch and innovation; durable, by decisive orientation to a new economy with low-emisions of carbon dioxide and favorable to inclusion, by focusing on creating jobs and redcuing poverty. The priorites of the strategy will be achieved through five objectives, one which is linked to emplyment, namely: employment rate of 75% for population aged between 20 and 64 years. Providing such rate of occupancy implies policies at microeconomical level, but we consider also at individual level. So the young, future employees must be properly trained, and have the right to be able to handle a job. Current realities show that employers are interested in having by their side in accomplishing their goals, employees who are proactive, who improvise, who can cope with various demands in which they are involved, and respond positively to companies. They require a career choice to meet the vocational interests. Based on these issues, this paper aims to analyze the importance of knowing the vocational interests in school orientation by highlighting the correlation between the selected profile and personality of each. However, in this paper we try to show that school guidance is an early process and that if they knew their vocational interests, young people would be more decisive in the choice of future profession. We believe that, if the counseling activites and school oriantation would be conducted in a professiona way, youth might focus on those occupations which best define them and also could access appropriate university programs with favorable effects on employment levels.

    Mask preparation stages are crucial in mask manufacturing, since this mask is to later act as a template for considerable number of dies on wafer. Defects on the initial blank substrate, and subsequent cleaned and coated substrates, can have a profound impact on the usability of the finished mask. This emphasizes the need for early and accurate identification of blank substrate defects and the risk they pose to the patterned reticle. While Automatic Defect Classification (ADC) is a well-developed technology for inspection and analysis of defects on patterned wafers and masks in the semiconductors industry, ADC for mask blanks is still in the early stages of adoption and development. Calibre ADC is a powerful analysis tool for fast, accurate, consistent and automatic classification of defects on mask blanks. Accurate, automated classification of mask blanks leads to better usability of blanks by enabling defect avoidance technologies during mask writing. Detailed information on blank defects can help to select appropriate job-decks to be written on the mask by defect avoidance tools [1][4][5]. Smart algorithms separate critical defects from the potentially large number of non-critical defects or false defects detected at various stages during mask blank preparation. Mechanisms used by Calibre ADC to identify and characterize defects include defect location and size, signal polarity (dark, bright) in both transmitted and reflected review images, distinguishing defect signals from background noise in defect images. The Calibre ADC engine then uses a decision tree to translate this information into a defect classification code. Using this automated process improves classification accuracy, repeatability and speed, while avoiding the subjectivity of human judgment compared to the alternative of manual defect classification by trained personnel [2]. This paper focuses on the results from the evaluation of Automatic Defect Classification (ADC) product at MP Mask

  3. Enhancing EUV mask blanks usability through smart shift and blank-design pairing optimization

    2016-10-01

    EUV Defect avoidance techniques will play a vital role in extreme ultraviolet lithography (EUVL) photomask fabrication with the anticipation that defect free mask blanks won't be available and that cost effective techniques will not be available for defect repairing. In addition, mask shops may not have a large inventory of expensive EUV mask blanks. Given these facts, defect avoidance can be used as cost effective technique to optimize the mask blank and design data (mask data) pair selection across mask blank manufacturers and mask shops so that overall mask blank utilization can be enhanced. In previous work, it was determined that the pattern shift based solution increases the chance that a defective mask blank can be used that would otherwise be discarded [1]. In pattern shift, design data is shifted such that defects are either moved to isolated regions or hidden under the patterns that are written. However pattern shifts techniques don't perform well with masks with higher defect counts. Pattern shift techniques in this form assume all defects to be equally critical. In addition, a defect is critical or important only if it lands on the main pattern. A defect landing on fill, sub-resolution assist feature (SRAF) or fiducial areas may not be critical. In this paper we assess the performance of pattern shift techniques assuming defects that are not critical based upon size or type, as well as defects landing in non-critical areas (smart shift) can be ignored. In a production mask manufacturing environment it is necessary to co-optimize and prioritize blank-design pairing for multiple mask layouts in the queue with the available blanks. A blank-design pairing tool maximizes the utilization of blanks by finding the best pairing between blanks and design data so that the maximum number of mask blanks can be used. In this paper we also propose a novel process which would optimize the usage of costly EUV mask blanks across mask blank manufacturers and mask shops

    Full Text Available ABSTRACT: The blanking process can be simulated by ABAQUS v 6.4 to select punch, die and press and ascertain punch wear and bur height. The experimental and the simulation results agree well with rising punch force up to the point of creation of crack. For a 2mm mild steel sheet, the simulation shows that for the punch force of 240 kN, the crack starts at 30% punch penetration depth and punch force suddenly drops to a value of 70 kN and remains steady till the blanking is complete. Comparing simulation and experimental results for a 3mm mild steel sheet, results agree well in the elastic range with the punch force rising up to point of crack creation. However, a discrepancy appears in punch force which increases with punch penetration. At 32% depth of penetration, the discrepancy is 12 % which increases to 60 % at punch penetration of 42%. Punch force for experimental and simulation results remains about 90kN beyond punch penetration of 62%. Also, increase of the thickness of sheet results in reduced crack height and improved quality of blank.ABSTRAK: Proses pengosongan boleh disimulasikan oleh ABAQUS versi 6.4 untuk memilih tebuk, alat dan tekan; dan menentukan haus tebuk dan ketinggian duri.

  16. An electron optical theory of beam blanking

    Science.gov (United States)

    Gesley, M.

    1993-11-01

    Trajectory equations are derived in closed form for electrons in time-dependent electric fields produced by beam blankers. Simple parallel plate and double-deflection blankers with transmission delay lines are evaluated. Lens imaging of the apparent beam motion is analyzed by developing the virtual electron trajectories obtained from linear extrapolation back into the blanker region. Lens excitation effects and conjugate blanking optics can then be described. The blanker voltage is represented by a damped exponential cosine term, which satisfies a typical circuit equation for the driver-amplifier. The form of the trajectory equation is written as a 3×3 matrix, which comprises a set of conditional solutions that are determined by blanker geometry. The optimum delay line length of any double-deflection blanker can then be determined. The blanker-induced beam jitter is shown to be significantly reduced by using this configuration. The effect of the blanker beam stop on the motion at the target plane is given by combining results on the real and apparent beam trajectories.

    Near-Net-Shape (NNS) technology for advanced engineered materials provides a number of supply chain benefits. These benefits include less input material, less machining hours and overall greater through put in comparison to conventional rectangular and round machining stock. Al-62%Be alloy has a unique combination of properties attractive for optical structures. It has a density of 0.076-lb/in3, 28-ksi minimum yield strength and 28-Msi elastic modulus. There have been significant developments with AlBe Hot Isostatic Press (HIP) consolidation technology in recent years. One key is using spherical AlBe metal powder which packs to a high density. The high packing density allows more complex can design and dimensional control to produce monolithic parts with isotropic properties. Other key success factors are HIP can design and the process to implement the near-net-shape strategy. This paper will describe an example of a process using shaped HIP cans to produce blanks approaching near-net-shape design through an iterative process. The strategy is to produce a seamless product to the next step in the supply chain as the iterations improve material utilization efficiency. The economic impact and planned future work will also be described.

    As the designs of future mask nodes become more and more complex the corresponding pattern writing times will rise significantly when using single beam writing tools. Projection multi-beam lithography [1] is one promising technology to enhance the throughput compared to state of the art VSB pattern generators. One key component of the projection multi-beam tool is an Aperture Plate System (APS) to form and switch thousands of individual beamlets. In our present setup a highly parallel beam is divided into 43,008 individual beamlets by a Siaperture- plate. These micrometer sized beams pass through larger openings in a blanking-plate and are individually switched on and off by applying a voltage to blanking-electrodes which are placed around the blanking-plate openings. A charged particle 200x reduction optics demagnifies the beamlet array to the substrate. The switched off beams are filtered out in the projection optics so that only the beams which are unaffected by the blanking-plate are projected to the substrate with 200x reduction. The blanking-plate is basically a CMOS device for handling the writing data. In our work the blanking-electrodes are fabricated using CMOS compatible add on processes like SiO2-etching or metal deposition and structuring. A new approach is the implementation of buried tungsten electrodes for beam blanking.

    Full Text Available Majority of automobile and appliances component are made by deep drawing sheet metal process. So these growing need demands a new design methodology based on metal forming simulation. With the help of metal forming simulation we can identify the problem areas and solutions can be validated in computers without any expensive shop floor operations prior to any tool construction. Metal forming simulation is also helpful at the product and tool design stage to decide various parameters. Problem and improvements in each area of the SDF technology and their interactions should be considered. In the product and process design phases in order to optimize Blank Holding Force which is one of the important parameters in Deep Drawing process. Sometimes accuracies of frictional values have more effect on the simulation results than most of the material properties. So that friction plays a major role during optimization of Blank Holding Force. In this paper, the friction is varied in six different values. CRDQ Steel is used as a material. For each value of friction and its corresponding B.H.F., Forming Limit Diagrams are drawn by using hyper mesh module of Hyper Form Solver software. Also the effect of these two parameters on occurrence of wrinkling during the process is studied. Thus, optimized range of coefficient of friction in which product is safe as well as having minimized wrinkles along with optimized B.H.F. is calculated.

    2011-05-01

    Friction stir welded blanks (FSWB) are tailored blanks made by friction stir welding of sheets of different thicknesses and quality. In order to reduce the trial-and-error principles and costs, the computational simulation of stamping processes of FSW blanks is required for which a feasible methodology or theory to evaluate the forming characteristics has to be incorporated. In the present work, the validity of effective strain rate based necking criterion (ESRC) in both original and modified forms to predict the forming limit of FSW blanks made of AA6111, DP590 is analyzed. The FLC thus predicted is compared with FLC from thickness gradient based necking criterion and from literature. It is found from the validation done with literature results that a consistent and accurate forming limit prediction is obtained from modified ESRC when compared to original ESRC. The failure pattern prediction is also agreeing well with the literature results.

    SCHOTT produces the zero expansion glass ceramics material ZERODUR since 35 years. More than 250 ZERODUR mirror blanks were already delivered for the large segmented mirror telescopes KECK I, KECK II, HET, GTC, and LAMOST. Now several extremely large telescope (ELT) projects are in discussion, which are designed with even larger primary mirrors (TMT, OWL, EURO50, JELT, CFGT, GMT). These telescopes can be achieved also only by segmentation of the primary mirror. Based on the results of the recent production of segment blanks for the GTC project the general requirements of mirror blanks for future extremely large telescope projects have been evaluated. The specification regarding the material quality and blank geometry is discussed in detail. As the planned mass production of mirror blanks for ELT's will last for several years, economic factors are getting even more important for the success of the projects. SCHOTT is a global enterprise with a solid economical basis and therefore an ideal partner for the mirror blank delivery of extremely large telescopes.

    2006-01-01

    Constituting the reasonable control models of the wrinkle limit blank holder forces is the sticking point of the processes of the deep drawing with variable blank-holder forces, especially in the square-box forming. To begin with, a mode of segmenting flange of the square-box into eight zones is put forward according to the fact that the uniformity of flange deforming can be improved by controlling segment blank-holders. Considering the integral influence of shear stress, a new concept, strain relaxation factor is defined. Hereby, the law of distribution of stress and stain in the deforming flange of square-box is achieved. Then based on these mechanical analysis models and the energy principle,the wrinkling flexivity functions of the straight flange and the circle flange are given, and the corresponding formulae of wrinkling limit blank-holder force in these two situations are also educed. In these processes, ply-anisotropy, strain hardening, thickness and friction are considered. In the end, a calculating example is designed to validate the rationality of the formulae of wrinkling limit blank-holder force, at the same time, the influences of the ply-anisotropy exponent and the strain hardening exponent on the wrinkle limit blank holder forces are also analyzed.

    2016-07-01

    The upcoming extremely large telescope projects like the E-ELT, TMT or GMT telescopes require not only large amount of mirror blank substrates but have also sophisticated instrument setups. Common instrument components are atmospheric dispersion correctors that compensate for the varying atmospheric path length depending on the telescope inclination angle. These elements consist usually of optical glass blanks that have to be large due to the increased size of the focal beam of the extremely large telescopes. SCHOTT has a long experience in producing and delivering large optical glass blanks for astronomical applications up to 1 m and in homogeneity grades up to H3 quality in the past. The most common optical glass available in large formats is SCHOTT N-BK7. But other glass types like F2 or LLF1 can also be produced in formats up to 1 m. The extremely large telescope projects partly demand atmospheric dispersion components even in sizes beyond 1m up to a range of 1.5 m diameter. The production of such large homogeneous optical glass banks requires tight control of all process steps. To cover this demand in the future SCHOTT initiated a research project to improve the large optical blank production process steps from melting to annealing and measurement. Large optical glass blanks are measured in several sub-apertures that cover the total clear aperture of the application. With SCHOTT's new stitching software it is now possible to combine individual sub-aperture measurements to a total homogeneity map of the blank. In this presentation first results will be demonstrated.

    This paper presents experimental and numerical results for the quench of a gear blank in agitated and stagnant oil. Heat transfer within the gear blank is analyzed with a whole domain-optimizer technique inverse solution method, to calculate the time history at every point in the gear blank. The development of this procedure represents the first stage in an overall analysis of the quench process that will later include material phase transformations and deformation. The paper presents ten variations in setting up the inverse problem, to analyze which combination of independent variables and decision variables results in the best match between experimental and numerical results. The results indicate that dividing the boundary of the gear blank into four zones and assigning a fixed heat transfer coefficient or heat flux to each zone yields an average RMS error (average difference between experimental and numerical results) of the order of 40 K. This error can be reduced by either increasing the number of zones, by reducing the number of thermocouples being matched, or by allowing the heat transfer or heat flux to vary within the zones. Of these possibilities, variation of heat transfer within the zones gives the best improvement in the quality of the match for the amount of extra effort required to run the problem.

    The application of fine blanking to the manufacturing of helical gears directly from a strip has been restricted due to the traditional linear cutting stroke of the punch and die. In this work, rotational fine blanking which combined the linear and rotational motion of punch and counterpunch was applied for the forming of helical gears. A three-dimensional (3D) rigid-plastic finite element model was developed on the DEFORM-3D platform. By finite element simulation and analysis, the influences of key parameters on the punch load and cut surface were investigated. It is shown that:1) with increasing the counterforce or helical angle, the punch load and the depth of die roll increase;2) with increasing blank holder force, the punch load increases while the depth of die roll decreases;3) V-ring indenter facilitates an improvement in the quality. The results of this research reveal the deformation mechanism of rotational fine blanking of helical gears, and provide valuable guidelines for further experimental studies.

    Wound infections after gunshot wounds from live ammunition can produce serious complications. It is well known that projectiles per se are neither sterile nor does their firing cause sterilization. The germs on the surface of a projectile enter the body together with the projectile and are thus introduced into the wound together with skin bacteria. However it is less known that wound infections can occur in wounds caused by the gas jet from blank ammunition (mainly from shots at very close range). In such ammunition without a projectile, the propellant particles are usually contaminated with bacteria which find their way into the wound together with skin germs. In previous investigations, we have microbiologically detected the species Bacillus cereus in the propellant of blank cartridges. In the present study, we have applied scanning electron microscopic methods to find out which areas of the blank cartridges are colonized by these bacteria. For this purpose 20 blank cartridges, each from 4 different manufacturers, were electronmicroscopically examined. B. cereus only found on the surface of intact nitrocellulose particles but not in the interior of broken prepared propellant particles. Bacterial structures were not morphologically identified on black powder particles.

    Development and characterization of friction stir welded aluminum tailor welded blanks was successfully carried out on three separate machine platforms. Each was a commercially available, gantry style, multi-axis machine designed specifically for friction stir welding. Weld parameters were developed to support high volume production of dissimilar thickness aluminum tailor welded blanks at speeds of 3 m/min and greater. Parameters originally developed on an ultra-high stiffness servo driven machine where first transferred to a high stiffness servo-hydraulic friction stir welding machine, and subsequently transferred to a purpose built machine designed to accommodate thin sheet aluminum welding. The inherent beam stiffness, bearing compliance, and control system for each machine were distinctly unique, which posed specific challenges in transferring welding parameters across machine platforms. This work documents the challenges imposed by successfully transferring weld parameters from machine to machine, produced from different manufacturers and with unique control systems and interfaces.

    In many industrials field, especially in the automotive sector, there is a trend toward lightweight constructions in order to reduce the weight and thereby the CO₂ and NOx emissions of the products. An auspicious approach within this context is the substitution of conventional deep drawing steel by precipitation hardenable aluminum alloys. However, based on the low formability, the application for complex stamping parts is challenging. Therefore, at the Institute of Manufacturing Technology, an innovative technology to enhance the forming limit of these lightweight materials was invented. The key idea of the so-called Tailor Heat Treated Blanks (THTB) is optimization of the mechanical properties by local heat treatment before the forming operation. An accurate description of material properties is crucial to predict the forming behavior of tailor heat treated blanks by simulation. Therefore, within in this research project, a holistic approach for the design of the THTB process in dependency of the main influencing parameters is presented and discussed in detail. The capability of the approach for the process development of complex forming operations is demonstrated by a comparison of local blank thickness of a tailgate with the corresponding results from simulation.

    Welded sheets with different thicknesses are one of the interesting types of tailor-welded blanks (TWBs) that are widely used in metal-forming industries. In the present work, the formability behavior of different 1100-aluminum TWBs was studied. In this regard, the TWBs were made with different thickness ratios by using friction stir welding (FSW) at different welding rotational speeds ( ω). The thickness ratios of 1.0, 1.3, and 1.7 were investigated where the thinner sheets had 1.5 mm thick for all conditions; i.e., the volume of welded material increased when the thickness ratio increased. Macrostructural observations, mechanical investigations, and sheet-forming limit tests were conducted. The results indicate that increasing ω leads to increasing the weld nugget size up to a maximum level and welding became impossible at higher ω. Furthermore, increasing heat input during FSW, the ultimate tensile strength of welds reduced in comparison with the initial cold-worked base metal. However, the ductility improved by increasing the heat input, which produced the sound welds. Formability studies of the friction stir-welded blanks with equal thicknesses have shown that the forming ratio improves up to 2.8 times the base metal. Forming limit curves also illustrate that increasing the thickness ratio of TWB causes the formability ratio to decrease steadily. Thus, when the thickness ratio becomes 1.7, the formability of TWB decreases approximately to the thinnest base metal.

    2015-07-01

    A blank mask and its preparation stages, such as cleaning or resist coating, play an important role in the eventual yield obtained by using it. Blank mask defects' impact analysis directly depends on the amount of available information such as the number of defects observed, their accurate locations and sizes. Mask usability qualification at the start of the preparation process, is crudely based on number of defects. Similarly, defect information such as size is sought to estimate eventual defect printability on the wafer. Tracking of defect characteristics, specifically size and shape, across multiple stages, can further be indicative of process related information such as cleaning or coating process efficiencies. At the first level, inspection machines address the requirement of defect characterization by detecting and reporting relevant defect information. The analysis of this information though is still largely a manual process. With advancing technology nodes and reducing half-pitch sizes, a large number of defects are observed; and the detailed knowledge associated, make manual defect review process an arduous task, in addition to adding sensitivity to human errors. Cases where defect information reported by inspection machine is not sufficient, mask shops rely on other tools. Use of CDSEM tools is one such option. However, these additional steps translate into increased costs. Calibre NxDAT based MDPAutoClassify tool provides an automated software alternative to the manual defect review process. Working on defect images generated by inspection machines, the tool extracts and reports additional information such as defect location, useful for defect avoidance[4][5]; defect size, useful in estimating defect printability; and, defect nature e.g. particle, scratch, resist void, etc., useful for process monitoring. The tool makes use of smart and elaborate post-processing algorithms to achieve this. Their elaborateness is a consequence of the variety and

  3. Numerical investigation of blanking for metal polymer sandwich sheets

    Gutknecht Florian

    2016-01-01

    Full Text Available Metal polymer sandwich sheets consist of materials with drastically different mechanical properties. Due to this fact and because of high local gradients in the cutting zone during the blanking process, traditional process strategies and empirical knowledge are difficult to apply. A finite-element simulation of the shear cutting process is used to predict the necessary force and the geometry of the cutting surface. A fully-coupled ductile damage model is used for the description of the material behaviour. This model considers the influence of shear and compression-dominated stress states on the initiation of damage. Experimental tensile and compression test data is used for the identification of material parameters. The results of the blanking simulation are compared with experimental data. Furthermore, the evolution of the stress state is analysed to gain understanding of the underlying physics. Finally this model enables the prediction of core compression and other quantities such as the acting stresses and corresponding triaxilities, which provide valuable information for the development of analytical models.

    Commercial cinema is both narrative art and a widely-used mass medium that is built upon human stories. Among the contents of these stories there are many vocational aspects. Taking advantage of these circumstances we will proceed to analyze health vocations through eight films. Patch Adams allows us to approach the fulfillment of vocation, which has not been an easy task for women, as we can see in Allá en el setenta y tantos. Vocational fulfillment is at the core of the plot in The Citadel. Something the Lord Made is a good example to illustrate an unfulfilled vocation, in the same way as Awakenings and Arrowsmith represent the fulfillment of an unexpected vocation and a long pursued one. Finally, vocation can demand great sacrifices, which is made crystal clear in Korczak, and when vocation is not strictly followed it might lead to the greatest abominations, which is the case in "The Fugitive.

    As the number of masks per wafer product set is increasing and low k1 lithography requires tight mask specifications, the patterning process below sub 20nm tech. node for critical layers will be much more expensive compared with previous tech. generations. Besides, the improved resolution and the zero defect level are necessary to meet tighter specifications on a mask and these resulted in the increased the blank mask price as well as the mask fabrication cost. Unfortunately, in spite of expensive price of blank masks, the certain number of defects on the blank mask is transformed into the mask defects and its ratio is increased. But using high quality blank mask is not a good idea to avoid defects on the blank mask because the price of a blank mask is proportional to specifications related to defect level. Furthermore, particular defects generated from the specific process during manufacturing a blank mask are detected as a smaller defect than real size by blank inspection tools because of its physical properties. As a result, it is almost impossible to prevent defects caused by blank masks during the mask manufacturing. In this paper, blank defect types which is evolved into mask defects and its unique characteristics are observed. Also, the repair issues are reviewed such as the pattern damage according to the defect types and the repair solution is suggested to satisfy the AIMS (Arial Image Measurement System) specification using a nanomachining tool.

Current China’s Labor Law and other legal norm for adjusting labor relationship do not give a clear regulation for vocational college student to clear the labor subject qualification during post practice. Hence, how to guarantee vocational college student’s labor rights and interests, such as labor right to labor rewards, right to rest, right of labor insurance, and to provide legal advocacy channels for those being infringed on labor rights is urgent subject for comprehensive realization of particular talent cultivation of higher vocational education. Based on the current state, there are two relief channels: The first is legislative and judicial relief, the second is to sign the tripartite intern agreement, add to commercial insurance, and establish labor rights and interests security and early warning mechanism.

    2005-01-01

    The effect of commercial frequency electromagnetic field on the solidification structure and mechanical properties of copper hollow blanks prepared by horizontal continuous casting method was investigated. The results show that when the electromagnetic field is imposed, columnar grains are evidently refined and fine equiaxed grains are obtained in the inner side of the cross-section. Moreover, with the increase of input current, the equiaxed grain region widens and the grains distribute more uniformly in the circumferential direction. Meanwhile, the mechanical properties are remarkably improved by the application of electromagnetic field. When the input current is 140 A, the tensile strength increases 15% and the elongation increases 10%. However, the electromagnetic field has no effect on the distribution of microelements.

In order to solve this problem, the paper proposed a new kind of algorithm combining CHNN and genetic algorithm. It set up models for irregular parts, and these irregular parts were processed by using the surrounding rectangle methods and graphic composition. The paper used AutoCAD as a develop studio, and discussed CHNN and its mapping to layout and optimize the weight of CHNN by genetic algorithm. The kernel program adopted VB program language and developed the intelligent layout system. With the input of layout parts graphics and layout parameter, the system preprocessed graphics and gave layout results automatically. Sample analysis showed the results that the system had good man-machine interfaces, interactive features, high speed and quality retention of solution.

    Full Text Available In this paper, an overall review of the different parameter affecting on formability of tailor-welded blanks process is presented so that other researchers can concentrate on same to further critical investigations in this area. Tailor-welded blanks has been widely used in automobile and aerospace application now-a-days. It is the combination of more than or equal to two sheets having different material, thickness and coatings. Efforts have been put for determining the formability of TWB by various authors. Authors have been compared various test data for formability tests of TWB analytically with the help of various software. They have compared analytical data with practical data which were carried out in early 90’s for formability test when various software were not available. The testing of data and analyzing them by generating Forming Limit Diagram (FLD for various tests parameters carried out by Limit Dome Height (LDH test has been being much simpler analytically rather than conducting them practically. The efforts have also been put to conduct data and to verifying them analytically for deep drawing process of formability for TWB sheets with the help of various available software codes. Future scope may include to conduct data practically and to analyzed them by varying various test parameters for deep drawing process of a cylindrical cups on a new software HYPERWORKS which is now-a-days immerging as a powerful tool for software applications due to its some key features of being more efficient and accurate than other available software codes. The analyzing process is very fast, reliable and accurate compare to other finite element code available in the market.

    Extreme ultraviolet lithography (EUVL) mask multi-layer (ML) blank surface roughness specification historically comes from blank defect inspection tool requirement. Later, new concerns on ML surface roughness induced wafer pattern line width roughness (LWR) arise. In this paper, we have studied wafer level pattern LWR as a function of EUVL mask surface roughness via High-NA Actinic Reticle Review Tool. We found that the blank surface roughness induced LWR at current blank roughness level is in the order of 0.5nm 3σ for NA=0.42 at the best focus. At defocus of ±40nm, the corresponding LWR will be 0.2nm higher. Further reducing EUVL mask blank surface roughness will increase the blank cost with limited benefit in improving the pattern LWR, provided that the intrinsic resist LWR is in the order of 1nm and above.

    During the last years, one of the most interesting subjects in the automotive industry is the weight reduction of the automobile, and so to diminish the fuel consumption. Among other performance, the use in the body car of materials which have high mechanical resistance must be considered for the weight reduction of the automobile and maintaining high benefits. In this work, it has been studied the utilization of the diode laser for high resistance steel sheets welding, concretely microalloying steels (ZStE), DP dual phase and TRIP transformation induced plasticity. These steels can be employed in tailored blanks, which are defined as two or more separate pieces of flat material of dissimilar thickness and/or physical properties joined together before forming, to provide superior qualities in the finished stamped part. In this study, the metallographic characterization has been realised in the welding seams, and the mechanical behaviour has been analysed employing the following tests: microhardenss, drawing, tensile and fatigue.

    Full Text Available The development of the approximate blank size should be done to determine the size of a blank to produce the shell to the required depth and to determine how many draws will be necessary to produce the shell. This is determined by the ratio of the blank size to the shell size. Various methods have been developed to determine the size of blanks for drawn shells. These methods are based on algebraic calculations; the use of graphical layouts; a combination of graphical layouts and mathematics.

  19. Mind-blanking: When the mind goes away

    Directory of Open Access Journals (Sweden)

    2013-09-01

    Full Text Available People often feel like their minds and their bodies are in different places. Far from an exotic experience, this phenomenon seems to be ubiquitous facet of human life (e.g., Killingsworth & Gilbert, 2010. Many times, people’s minds seem to go somewhere else—attention becomes disconnected from perception, and people’s minds wander to times and places removed from the current environment (e.g., Schooler, Reichle & Halpern, 2004. At other times, however, people’s minds may seem to go nowhere at all—they simply disappear. This mental state—mind-blanking—may represent an extreme decoupling of perception and attention, one in which attention fails to bring any stimuli into conscious awareness. In the present research, we outline the properties of mind-blanking, differentiating this mental state from other mental states in terms of phenomenological experience, behavioral outcomes, and underlying cognitive processes. Seven experiments suggest that when the mind seems to disappear, there are times when we have simply failed to monitor its whereabouts—and there are times when it is actually gone.

  1. Quasi-Newton Method for Optimal Blank Allowance Balancing

    A balancing technique for casting or forging parts to be machined is presented in this paper. It allows an optimal part setup to make sure that no shortage of material (undercut) will occur during machining. Particularly in the heavy part industry, where the resulting casting size and shape may deviate from expectations, the balancing process discovers whether or not the design model is totally enclosed in the actual part to be machined. The alignment is an iterative process involving nonlinear constrained optimization, which forces data points to lie outside the nominal model under a specific order of priority. Newton methods for non-linear numerical minimization are rarely applied to this problem because of the high cost of computing. In this paper, Newton methods are applied to the balancing of blank part. The aforesaid algorithm is demonstrated in term of a marine propeller blade, and result shows that The Newton methods are more efficient and accurate than those implemented in past research and have distinct advantages compared to the registration methods widely used today.

    A coupled electrical-thermal-mechanical analysis is conducted for electrical/laser heating assisted blanking. Two novel localized-heating methods, electrical heating and laser-heating, recently proposed for small-part blanking, are investigated with FE simulations. Results show that electrical heating would result in an advantageous distribution of temperature in a 316 stainless steel work-material. A desired temperature distribution may also be achievable for a copper work-material,if laser beam is used. Both electrical heating and laser-heating enable to reduce the blanking force and increase the aspect ratio achievable by blanking. The simulation also demonstrates that both electrical heating and laser-heating can result in desired temperature-distributions at sufficiently high heating-rates, ease of implementation and application. Comparatively, electrical heating could generate more favorable temperature distribution for small-part blanking.

    Aiming at solving the difficulties of deforming manufacture of the automobile rear axle bevel gear blank, the paper presented to adopt the numerical simulation method to study the rolling process of the bevel gear blank instead of the traditional expensive trail-and-error method. A three-dimensional simulation model of the Φ500 bevel gear blank radial ring rolling machine was firstly created based on the general dynamic explicit finite element code ANSYS/LS-DYNA, and then realized the virtual simulation of the entire rolling process of the bevel gear blank within a producing cycle. The simulation results displayed the real-time blank enlarging and fleck generating as well as the stress, strain and displacement contours, which are in good agreements with the real ring rolling process. It is concluded that this numerical simulation method is feasible and can be used to guide the practical rolling process of the bevel gear blank as well as other profile-shaped annular blanks.

    Analog blanking periods (BPs) that hold down the display of electrograms (EGMs) in cardiac rhythm devices have received much less attention than the well-known digital BPs which do not influence the EGM display. In Biotronik devices (Biotronik GmbH, Berlin, Germany), when a paced event initiates an analog BP in one chamber (right atrium, right ventricle [RV], or left ventricle [LV]), an identical cross-chamber analog BP starts in the other two chambers. All clinical observations were recorded from patients with Biotronik devices. The effect of the atrial cross-chamber analog BP initiated by a ventricular paced event on the atrial EGM was studied in the records of seven patients with frequent paroxysmal atrial flutter to determine the effect of critically timed RV paced event (RVp) or LV paced event (LVp) upon the atrial EGM. The effect of atrial pacing triggering cross-chamber analog BPs in the RV and LV channels on the RV and LV EGMs was also investigated in cases of conducted supraventricular beats and ventricular premature complexes. The effect of a triggered LVp initiating a cross-chamber analog BP in the RV channel on the EGM of a sensed RV sensed event was evaluated in 10 cases. Simulation studies were also performed to verify the clinical observations. Patients with atrial flutter showed intermittent truncation or deformity and even disappearance of the atrial signals due to an atrial cross-chamber analog BP initiated by RVp and/or LVp. Three patients demonstrated deformity of the signal shape of ventricular premature beats falling within a ventricular cross-chamber analog BP initiated by right atrial paced event (RAp). We found only one case of a supraventricular QRS complex trapped in a ventricular cross-chamber analog BP initiated by RAp. All the recordings of LVp triggering upon RVs revealed a variety of RV signal deformities occasionally with preservation of the terminal part of the RV signal. Simulation studies confirmed the effect of the analog BP on

  14. Spatial Biases During Mental Arithmetic: Evidence from Eye Movements on a Blank Screen

    Directory of Open Access Journals (Sweden)

    Matthias eHartmann

    2015-01-01

    Full Text Available While the influence of spatial-numerical associations in number categorization tasks has been well established, their role in mental arithmetic is less clear. It has been hypothesized that mental addition leads to rightward and upward shifts of spatial attention (along the mental number line, whereas subtraction leads to leftward and downward shifts. We addressed this hypothesis by analyzing spontaneous eye movements during mental arithmetic. Participants solved verbally presented arithmetic problems (e.g., 2+7, 8-3 aloud while looking at a blank screen. We found that eye movements reflected spatial biases in the ongoing mental operation: Gaze position shifted more upward when participants solved addition compared to subtraction problems, and the horizontal gaze position was partly determined by the magnitude of the operands. Interestingly, the difference between addition and subtraction trials was driven by the operator (plus vs. minus but was not influenced by the computational process. Thus, our results do not support the idea of a mental movement toward the solution during arithmetic but indicate a semantic association between operation and space.

    Compound-specific radiocarbon analysis (CSRA) of amino acids (AAs) is of great interest as a proxy for organic nitrogen (N) cycling rates, dating archeological bone collagen, and investigating processes shaping the biogeochemistry of global N reservoirs. However, recoverable quantities of individual compounds from natural samples are often insufficient for radiocarbon ((14)C) analyses (quantification of C blanks (including sources, magnitudes, and variability) for a high-pressure liquid chromatography (HPLC) method designed to purify individual AAs from natural samples. We used pairs of AA standards with either modern (M) or dead (D) fraction modern (Fm) values to quantify MC and DC blanks within several chromatographic regions. Blanks were determined for both individual and mixed AA standard injections with peak loadings ranging from 10 to 85 μg C. We found 0.8 ± 0.4 μg of MC and 1.0 ± 0.5 μg of DC were introduced by downstream sample preparation (drying, combustion, and graphitization), which accounted for essentially the entire procedural blank for early eluting AAs. For late-eluting AAs, higher eluent organic content and fraction collected volumes contributed to total blanks of 1.5 ± 0.75 μg of MC and 3.0 ± 1.5 μg of DC. Our final measurement uncertainty for 20 μg of C of most AAs was ±0.02 Fm, although sample size requirements are larger for similar uncertainty in late-eluting AAs. These results demonstrate the first CSRA protocol for many protein AAs with uncertainties comparable to the lowest achieved in prior studies.

    2012-10-01

    Wells ("The psychology of lineup identifications," Journal of Applied Social Psychology, 1984, 14, 89-103) proposed that a blank lineup (an initial lineup of known-to-be-innocent foils) can be used to screen eyewitnesses; witnesses who chose from a blank lineup (initial choosers) were more likely to make an error on a second lineup that contained a suspect than were witnesses who rejected a blank lineup (initial nonchoosers). Recent technological advances (e.g., computer-administered lineups) may overcome many of the practical difficulties cited as a barrier to the use of blank lineups. Our research extended knowledge about the blank lineup procedure by investigating the underlying causes of the difference in identification performance between initial choosers and initial nonchoosers. Studies 1a and 1b (total, N = 303) demonstrated that initial choosers were more likely to reject a second lineup than initial nonchoosers and witnesses who did not view a blank lineup, implying that cognitive biases (e.g., confirmation bias and commitment effects) influenced initial choosers' identification decisions. In Study 2 (N = 200), responses on a forced-choice identification test provided evidence that initial choosers have, on average, poorer memories for the culprit than do initial nonchoosers. We also investigated the usefulness of blank lineups for interpreting identification evidence. Diagnosticity ratios suggested that suspect identifications made by initial nonchoosers (cf. initial choosers) should have a greater impact on estimates of the likely guilt of the suspect. Furthermore, for initial nonchoosers, higher confidence in blank lineup rejections was associated with higher diagnosticity for subsequent suspect identifications. These results have implications for policy to guide the collection and interpretation of identification evidence. PsycINFO Database Record (c) 2012 APA, all rights reserved.

    Husson, Ch.; Ahzi, S.; Daridon, L.

    2006-08-01

    To optimize the blanking process of thin copper sheets ( ≈ 1. mm thickness), it is necessary to study the influence of the process parameters such as the punch-die clearance and the wear of the punch and the die. For high stroke rates, the strain rate developed in the work-piece can be very high. Therefore, the material modeling must include the dynamic effects.For the modeling part, we propose an elastic-viscoplastic material model combined with a non-linear isotropic damage evolution law based on the theory of the continuum damage mechanics. Our proposed modeling is valid for a wide range of strain rates and temperatures. Finite Element simulations, using the commercial code ABAQUS/Explicit, of the blanking process are then conducted and the results are compared to the experimental investigations. The predicted cut edge of the blanked part and the punch-force displacement curves are discussed as function of the process parameters. The evolution of the shape errors (roll-over depth, fracture depth, shearing depth, and burr formation) as function of the punch-die clearance, the punch and the die wear, and the contact punch/die/blank-holder are presented. A discussion on the different stages of the blanking process as function of the processing parameters is given. The predicted results of the blanking dependence on strain-rate and temperature using our modeling are presented (for the plasticity and damage). The comparison our model results with the experimental ones shows a good agreement.

    2016-02-01

    In hot stamping, the determination of the thermal contact conductance values between the blank and tool surface during the process is crucial for the purpose of simulating the blank rapid cooling inside the tool using finite element analysis (FEA). The thermal contact conductance value represents the coefficient of the heat transfer at the surface of two solid bodies in contact and is known to be influenced greatly by the applied pressure. In order to estimate the value and its dependency on applied pressure, the process of hot stamping was replicated and simplified into a process of compression of heated flat blank in between the tool at different applied pressure. The temperature of the blank and tool surface were measured by means of thermocouples installed inside the tool. Based on the measured temperature, the thermal contact conductance between the surfaces was calculated using Newton's cooling law equation. The calculated value was then used to simulate the blank cooling inside the tool using FEA commercial software. This paper describes an experimental approach to estimate the thermal contact conductance between a blank made of Boron Steel (USIBOR 1500) and tool made of Tool Steel (STAVAX). Its dependency on applied pressure is also studied and the experimental results were then compared with FEA simulations.

  8. Finite Element Simulation for Determining the Optimum Blank Shape for Deep Drawing Process

    Directory of Open Access Journals (Sweden)

    Mr. Ravikant Patel,

    2014-11-01

    Full Text Available Deep drawing is one of widely used sheet metal working process in industries to produce cup shaped components at a very high rate. The present study aims to determine the optimum shape of blank for deep drawing of cylindrical cup without ears. Earing is one of the major defects observed during deep drawing process due to anisotropic nature of sheet metal. Earing is defined as formation of waviness on uppermost portion of deep drawn cup. Earing defect occurs due to non-uniform material properties within plane of sheet (i.e. planar anisotropy. Knowledge about ear formation in deep drawing process allows a prior modification of process which can result in defect free final product with financial saving and time. In the present study efforts have been made to study the earing problem in deep drawing of cylindrical cups by finite element modeling software HYPERWORK-6.12. The blank material as EN10130Fe01 mild steel sheet of 1mm thickness has been considered as it has wide application a fabricating critical automobile parts. Mechanical parameters of mild steel are incorporated in finite element simulation of deep drawing process. Significant earing was observed at rolling and transverse direction on deformed cup form circular blank. Modification of initial blank is done to find the optimum blank to reduce the earing defect. Optimal blank shows significant reduction of % earing height, reduction in drawing load & improvement in maximum thickness variations.

    顶岗实习是职业院校校企合作、工学结合人才培养模式的重要形式。由于立法的缺失,顶岗实习期学生权益受损情况较为普遍,并且权益受损后救济途径不明确,存在法律适用的困惑和归责的障碍。为有效保障学生顶岗实习权益,首先要加强立法保护,其次是构建全新的学生顶岗实习权益保障制度,包括建立实习劳动基准制度、完善实习指导制度、健全实习劳动伤害事故的法律保护制度、推行实行协议制度、建立实习监督机制。%Internship is an important form of talent training mode of school -enterprise cooperation and the occupation -study combination. It is very common for the internship students to face the violation of rights and interests due to the lack of legislation, unclear relief channel after violation, and the confusion for law application and the obstacles of imputation as well. To effectively protect students’ rights and interests, the legislative must be strengthened firstly; and secondly new regulations must be set up to protect students’ rights and interests, including building internship labor standard system, perfecting internship guidance system and the legal protection system of internship labor injury accidents, implementing protocol system, and establishing internship supervi⁃sion mechanism.

According to mould geometry parameters, blank geometry parameters, material mechanical parameters and processing parameters, an intelligent VBHF forecast model is proposed based on the BP neural network. Both of the response performance improvement and the intelligent control approach of the VBHF hydraulic loop are discussed. The accuracy compensation of the VBHF proportional integration differential control is realized by intelligent adaptive approach. Simulation and experimental results indicate that the forecast and intelligent control of VBHF for blank forming are realized effectively by this approach, which offers a theoretical support for the design of VBHF hydraulic press.

    2016-08-01

    The metal forming process through plastic deformation, represented by deep drawing, is an extremely vast research field. In this article we analyse the influence of the die punch clearance, the average velocity in the active phase as well as of the lubrication on the deep drawing quality revealed by the thickness evenness on the finished product surface. For thorough research and in order to minimize the number of experimental trials, a fractional factorial design of TAGUCHI type was developed attached to an orthogonal array, thus analysing the contribution of the three aforementioned parameters to the quality of cylindrical deep drawing without a blank holder. In order to compare the experimental results, a conceptual 3D model of the system punch-blank-die was made, which respects entirely the geometry of the active elements and of the blank, but schematizes/approximates the material properties of the blank. Thus, using these simulations, we can investigate the variation of the deformation parameters throughout the drawing process: from the initial blank form to the final drawn part. The numerical simulation of the drawing of cylindrical cups was made using the ANSYS V14 program, the Explicit Dynamic module. Using the signal-to-noise ratio suggested by TAGUCHI, we determined the influence of each of the three parameters under study on deep drawing quality, as well as their optimal values.

  15. Investigation into high-frequency-vibration assisted micro-blanking of pure copper foils

    Full Text Available The difficulties encountered during the manufacture of microparts are often associated with size effects relating to material, process and tooling. Utilizing acoustoplastic softening, achieved through a high-frequency vibration assisted micro-blanking process, was introduced to improve the surface finish in micro-blanking. A frequency of 1.0 kHz was chosen to activate the longitudinal vibration mode of the horn tip, using a piezoelectric actuator. A square hole with dimensions of 0.5 mm × 0.5 mm was made, successfully, from a commercial rolled T2 copper foil with 100 μm in thickness. It was found that the maximum blanking force could be reduced by 5% through utilizing the high-frequency vibration. Proportion of the smooth, burnished area in the cut cross-section increases with an increase of the plasticity to fracture, under the high-frequency vibration, which suggests that the vibration introduced is helpful for inhibiting evolution of the crack due to its acoustoplastic softening effect. During blanking, roughness of the burnished surface could be reduced by increasing the vibration amplitude of the punch, which played a role as surface polishing. The results obtained suggest that the high-frequency vibration can be adopted in micro-blanking in order to improve quality of the microparts.

  16. Artifacts Induced by Selective Blanking of Time-Domain Data in Fourier Transform Mass Spectrometry

    Fourier transform mass spectrometry (FTMS) of the isolated isotopic distribution for a highly charged biomolecule produces time-domain signal containing large amplitude signal "beats" separated by extended periods of much lower signal magnitude. Signal-to-noise ratio for data sampled between beats is low because of destructive interference of the signals induced by members of the isotopic distribution. Selective blanking of the data between beats has been used to increase spectral signal-to-noise ratio. However, blanking also eliminates signal components and, thus, can potentially distort the resulting FT spectrum. Here, we simulate the time-domain signal from a truncated isotopic distribution for a single charge state of an antibody. Comparison of the FT spectra produced with or without blanking and with or without added noise clearly show that blanking does not improve mass accuracy and introduces spurious peaks at both ends of the isotopic distribution (thereby making it more difficult to identify posttranslational modifications and/or adducts). Although the artifacts are reduced by use of multiple Gaussian (rather than square wave) windowing, blanking appears to offer no advantages for identifying true peaks or for mass measurement.

    Shots from blank weapons loaded with blank cartridges, when fired from close range or as a contact shot, almost always cause the skin to burst open and lead to injuries to structures below the surface. Subsequently, wound infections are often observed. In addition to the introduction of skin germs, the possibility exists that contaminated propellants may enter into consideration as a source of infection. Using step-by-step experimental procedures we were able to demonstrate that: 1. Blank cartridge propellants were almost always contaminated with Bacillus cereus (nitrocellulose powder more so than black powder); 2. When the shot is fired numerous bacteria survive and are forced out with the gunsmoke from the weapon and thus find their way into the wound. In principle, blank cartridge propellant thus exhibits as much potential for wound infection as the skin germs. Clearly, the species B. cereus is prominent in this context. For open injuries even with 'harmless' blank weapons, an antibiotic prophylaxis should always be administered.

    Wen, Y.; Chen, Z. H.; Zang, Y.

    2013-11-01

    In this paper, a blanking process of sheet metal is studied by the methods of numerical simulation and experimental observation. The effects of varying technological parameters related to the quality of products are investigated. An elastoplastic constitutive equation accounting for isotropic ductile damage is implemented into the finite element code ABAQUS with a user-defined material subroutine UMAT. The simulations of the damage evolution and ductile fracture in a sheet metal blanking process have been carried out by the FEM. In order to guarantee computation accuracy and avoid numerical divergence during large plastic deformation, a specified remeshing technique is successively applied when severe element distortion occurs. In the simulation, the evolutions of damage at different stage of the blanking process have been evaluated and the distributions of damage obtained from simulation are in proper agreement with the experimental results.

    Several automotive parts such as door panels have been manufactured by using load-adapted blanks for crash optimization and weight minimization.Recently, Tailor Rolled Blanks (TRB) has been introduced to remove the disadvantages of a welding process which was used in joining panel components.TRB offers better structural design capabilities due to the seamless transitions on the panels with different thicknesses.In spite of the advantages of the process, TRB leaves internal stresses in the panel.This residual stresses lower the formability of Tailor Rolled Blanked (TRBed) parts and cause cracks near severe curvature during subsequent forming processes.In this research, the residual stresses of TRBed Al5J32-T4 sheets were studied by X-ray stress analysis, and also microstructure was observed along the rolling direction.In addition, heat treatment was done after TRB process in order to compare the residual stresses to that of the TRBed sheets before the heat treatment.

    Blank cartridge guns are generally regarded as being harmless and are not considered to be firearms in the legal sense in most countries. To show the danger of these guns upon simple modifications, we report 59 fatalities resulting from these simply modified blank cartridge guns in Istanbul, Turkey. The great majority of the victims were males and the age of those ranged from 11 to 61 years. In 55.9% of these cases, homicide was the origin followed by suicide (39%). The right temporal region was detected to be the preferred region in suicidal shots by blank cartridge guns with a frequency of 56.5%. In trial shots, all these guns were detected to discharge steel or lead spherical objects, generally 4 or 5 mm in diameter, successfully. Our findings strongly suggest that these guns should also be considered as handguns in the legal sense.

  6. Control of Polishing Machine of Crystal Blank which Used Network Analyzer

    Wakamoto, Satoru; Nakazawa, Mitsuo

    Quartz crystal devices have become an essential factor in electronic equipment such as mobile communication equipment or PC. As prices of electronic equipment have lowered, the cost-down of quartz crystal devices has been strongly demanded. To achieve the cost-down of quartz crystal device manufacturing, which uses a complex manufacturing process, the yield of the quartz crystal blank lapping process, which is the preliminary process of the quartz crystal device manufacturing process, must be increased. By introducing the network analyzer to the quartz crystal blank lapping process, we have obtained real time lapping characteristics. By obtaining the new process characteristics in real-time and visualizing them when changing lapping conditions, the network analyzer can now optimize the conditions of the process. In addition, the network analyzer can now measure the optical quartz crystal blank polishing process, which was difficult to measure by using a conventional controller.

  7. Deep Drawing of High-Strength Tailored Blanks by Using Tailored Tools

    2016-01-01

    Full Text Available In most forming processes based on tailored blanks, the tool material remains the same as that of sheet metal blanks without tailored properties. A novel concept of lightweight construction for deep drawing tools is presented in this work to improve the forming behavior of tailored blanks. The investigations presented here deal with the forming of tailored blanks of dissimilar strengths using tailored dies made of two different materials. In the area of the steel blank with higher strength, typical tool steel is used. In the area of the low-strength steel, a hybrid tool made out of a polymer and a fiber-reinforced surface replaces the steel half. Cylindrical cups of DP600/HX300LAD are formed and analyzed regarding their formability. The use of two different halves of tool materials shows improved blank thickness distribution, weld-line movement and pressure distribution compared to the use of two steel halves. An improvement in strain distribution is also observed by the inclusion of springs in the polymer side of tools, which is implemented to control the material flow in the die. Furthermore, a reduction in tool weight of approximately 75% can be achieved by using this technique. An accurate finite element modeling strategy is developed to analyze the problem numerically and is verified experimentally for the cylindrical cup. This strategy is then applied to investigate the thickness distribution and weld-line movement for a complex geometry, and its transferability is validated. The inclusion of springs in the hybrid tool leads to better material flow, which results in reduction of weld-line movement by around 60%, leading to more uniform thickness distribution.

  8. Finite Element Optimization of Vee-ring Factor in Fine-blanking Process

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The vee-ring is one of the most characteristic features of the fine-blanking process which is derived from the conventional blanking. With the vee-ring, a counter plate and some other working parameters, a component with a precise geometry and smoothly blanked surface can be produced without any major secondary operations.However, these working parameters are always empirically determined or determined by trial-and-error method,which is time-consuming and expensive. In this study, a numerical simulation method was used to analyze the effect of vee-ring factors on product quality, such as distance between vee-ring and punch, vee-ring height and blank holder force, so as to obtain as high clean cut ratio as possible. During the simulation, the model was assumed as axisymmetric one and the workpiece was considered as rigid plastic material, meanwhile the tools were defined as rigid bodies so as to shorten the computational time. A damage model taking into account the influence of hydrostatic stress was used to simulate material fracture in fine-blanking. The result obtained from the simulation indicated that with the help of vee-ring, the metal material near the shear band does not flow with the punch penetration and high compressive stress in the shear band is generated. Consequently, higher clean cut ratio can be obtained with a vee-ring model than the one obtained with a plane blank holder model. Furthermore, the longer the distance between vee-ring and punch is, the higher the height of roll-over becomes.

    Full Text Available The main purpose of the current study is to examine the reliability and validity of a 55-item vocational interests scale prepared in light of Holland’s theory. According to Holland, there are six personality types in the workplace: Realistic, Investigative, Artistic, Social, Enterprising, and Conventional. People’s vocational personality is measured by looking at their vocational interests in this theory. 310 pre-service teachers from there departments including chemistry education, computer education/instructional technology and music education participated in the study. Results, in general, supported the premises of Holland’s theory. Although the results of confirmatory factor analysis supported the construct validity of the scale, 8 items possessed poor psychometric properties. As expected, there were significant differences among the pre-service teachers in these departments in terms of their vocational interests. The results of correlation and multi-dimensional scaling analyses produced contradictory results with the Holland’s hexagon. Although the propositions of Holland’s theory is not fully supported in the current study, we believe that our scale can be utilized confidently as an instrument to measure people’s vocational personality and help them to choose a career that fits their personality.

    Interests have been a central focus of counselling psychology (and vocational psychology in particular) for over 100 years. The awareness of professional interests increases self-knowledge and provides occupational information. In career counselling, vocational interests are assessed more frequently than any other vocational construct, though early evaluations (before 13 years old) of professional interests are very rare. The aim of this research is to examine the 3IP construct (Iconographic Professional Interests Inventory; an inventory composed of 65 stylised pictures that represent people in the act of performing a job) in depth, testing more models in addition to the 19 vocational areas proposed in the 3IP manual. Results show that most of the vocational areas can be grouped into 4 second-level areas ("things", "people", "leisure", and "culture"). Moreover, Holland's RIASEC model is tested; an accurate selection of items reveals that this model works well using 24 specific jobs. The research concludes that the inventory has good psychometric qualities which can grow further by mean of the increasing, in a targeted way, of the number of jobs.

    2015-09-01

    Electrocutaneous stimulation is a promising approach to provide sensory feedback to amputees, and thus close the loop in upper limb prosthetic systems. However, the stimulation introduces artifacts in the recorded electromyographic (EMG) signals, which may be detrimental for the control of myoelectric prostheses. In this study, artifact blanking with three data segmentation approaches was investigated as a simple method to restore the performance of pattern recognition in prosthesis control (eight motions) when EMG signals are corrupted by stimulation artifacts. The methods were tested over a range of stimulation conditions and using four feature sets, comprising both time and frequency domain features. The results demonstrated that when stimulation artifacts were present, the classification performance improved with blanking in all tested conditions. In some cases, the classification performance with blanking was at the level of the benchmark (artifact-free data). The greatest pulse duration and frequency that allowed a full performance recovery were 400 μs and 150 Hz, respectively. These results show that artifact blanking can be used as a practical solution to eliminate the negative influence of the stimulation artifact on EMG pattern classification in a broad range of conditions, thus allowing to close the loop in myoelectric prostheses using electrotactile feedback.

    Encapsulated isotopic heat sources for use in generating electrical power for space applications require flight-quality hardware material. Iridium is the chosen material for such applications, and Oak Ridge National Laboratory has been the prime supplier of iridium alloy forming blanks 52 mm in diameter by 0.66 mm thick (1.0 by 0.026 in.). Prior to the work reported here, these blanks were ultrasonically examined by using 0.9-mm-diam (0.035-in.) simulated flaw standards. However, as a result of this effort, the sensitivity of our ultrasonic pulse-echo test system has been increased. The improved ultrasonic test system permits blank inspection at the 0.5-mm-diam (0.020-in.) simulated flaw detection level. This test system was successfully demonstrated on the initial blanks provided via an improved processing route (consumable arc-melting, extruding, and rolling). The equipment modification and/or selection and the specific focused search unit immersion technique developed to provide this capability are described. The improved flaw detection capability also provides data maps of a common type of defect in iridium (delaminations).

  9. Enabling high speed friction stir welding of aluminum tailor welded blanks

    Science.gov (United States)

    Hovanski, Yuri

    Current welding technologies for production of aluminum tailor-welded blanks (TWBs) are utilized in low-volume and niche applications, and have yet to be scaled for the high-volume vehicle market. This study targeted further weight reduction, part reduction, and cost savings by enabling tailor-welded blank technology for aluminum alloys at high-volumes. While friction stir welding (FSW) has traditionally been applied at linear velocities less than one meter per minute, high volume production applications demand the process be extended to higher velocities more amenable to cost sensitive production environments. Unfortunately, weld parameters and performance developed and characterized at low to moderate welding velocities do not directly translate to high speed linear friction stir welding. Therefore, in order to facilitate production of high volume aluminum FSW components, parameters were developed with a minimum welding velocity of three meters per minute. With an emphasis on weld quality, welded blanks were evaluated for post-weld formability using a combination of numerical and experimental methods. Evaluation across scales was ultimately validated by stamping full-size production door inner panels made from dissimilar thickness aluminum tailor-welded blanks, which provided validation of the numerical and experimental analysis of laboratory scale tests.

  16. Blank corrections for ramped pyrolysis radiocarbon dating of sedimentary and soil organic carbon.

    Ramped pyrolysis (RP) targets distinct components of soil and sedimentary organic carbon based on their thermochemical stabilities and allows the determination of the full spectrum of radiocarbon ((14)C) ages present in a soil or sediment sample. Extending the method into realms where more precise ages are needed or where smaller samples need to be measured involves better understanding of the blank contamination associated with the method. Here, we use a compiled data set of RP measurements of samples of known age to evaluate the mass of the carbon blank and its associated (14)C signature, and to assess the performance of the RP system. We estimate blank contamination during RP using two methods, the modern-dead and the isotope dilution method. Our results indicate that during one complete RP run samples are contaminated by 8.8 ± 4.4 μg (time-dependent) of modern carbon (MC, fM ∼ 1) and 4.1 ± 5.5 μg (time-independent) of dead carbon (DC, fM ∼ 0). We find that the modern-dead method provides more accurate estimates of uncertainties in blank contamination; therefore, the isotope dilution method should be used with caution when the variability of the blank is high. Additionally, we show that RP can routinely produce accurate (14)C dates with precisions ∼100 (14)C years for materials deposited in the last 10,000 years and ∼300 (14)C years for carbon with (14)C ages of up to 20,000 years.

    2016-10-01

    A blanking apparatus was designed and built in order to study the effects of the process parameters on blanking low carbon steel disks, with particular reference to the study of punch-die gap influence and Brozzo's damage criterion by keeping punch and die fillet radii constant. The goal of the shearing tests was to optimize the gap between punch and die, according to the material damage and the force curves obtained by experimental tests. By using a 2D axis-symmetry FE model, the authors studied a set of parameters in order to reduce damage. After studying the material damage by a first simulation series, a second series was carried out in order to evaluate the punch-die gap effects on force-stroke trend; good results in term of external surface finish were obtained in the geometry of the final workpiece.

  3. Effect of blank holder pressure on viscous pressure forming aluminum alloy ladder parts

    2002-01-01

    Viscous pressure forming (VPF), is suitable for forming difficult-to-form sheet metal parts. An investigation in the effect of blank holder pressure (BHP) on VPF aluminum alloy ladder parts was conducted. Based on experimental and numerical simulation results of the effect of BHP on dimensional accuracy, wall-thickness reduction, forming pressure, material flow and defects (such as wrinkling and fracture) of specimens, the effect patterns of BHP load path on VPF ladder parts were explained. The limits of BHP corresponding to specimens with no defect and with wrinkling or fracture defect were determined. In the limits of formable BHP, the variable load path of BHP was beneficial to drawing blank into the die and decreasing wall-thickness reduction of specimens. The experimental results show that the ladder parts of good surface fineness and high dimensional accuracy can be obtained by variable load paths of BHP.

Thermodynamically-consistent constitutive equations, strongly coupled with ductile damage, together with specific boundary conditions (particular command of forces on blank holder and counterpunch) are presented. This model is implemented into ABAQUS/EXPLICIT using the Vumat user subroutine and connected with an adaptive 2D remeshing procedure. The different material parameters are identified for the steel S600MC using experimental tensile tests conducted until the final fracture. A parametric study aiming to examine the sensitivity of the process parameters (die radius, clearance die/punch) to the punch force and fracture surfaces topology (convex zone, sheared zone, fracture zone and the burr).

  5. Impact of Electronic Voting Machines on Blank Votes and Null Votes in Brazilian Elections in 1998

    2015-12-01

    Full Text Available Electronic voting machines were used for the first time in general elections in Brazil in 1998; in that year, some cities used this new voting method, while others continued to vote using paper ballots. Few studies have demonstrated that the rate of invalid votes for federal deputy was significantly lower in cities that used electronic voting machines. This article analyzes the frequency of null votes and blank votes for four posts—federal deputy, state deputy, the president and governor. Based on a comparison of the results from the 1998 elections with the results from previous elections (1994, the article demonstrates that electronic voting machines reduced the percentage of blank votes for federal deputy, state deputies, the president and governor. Meanwhile, null votes reduced the competition for the posts of federal deputy and state deputy; however, it increased the competition for posts with greater visibility in the Brazilian political system: the governor and president.

  6. Forming Of Spherical Titanium Cups From Circular Blanks With Cutouts On The Perimeter

    Directory of Open Access Journals (Sweden)

    Lacki P.

    2015-06-01

    Full Text Available Despite substantial demand for drawn parts made of high-strength sheet metal (including titanium alloys observed in the modern industry, particularly automotive and aviation, their application remains insignificant. This results from the fact that such sheet metal shows poor plasticity and its cold-forming is almost impossible. Low drawability makes it impossible to obtain even such simple shapes as spherical cups. The authors of this study developed circular sheet-metal blanks with cutouts on their perimeter. The blanks allow for cold forming of spherical cups from Ti6Al4V titanium alloy sheet metal using conventional rigid tools. The cutouts proposed in the study affect plastic strain distribution, which in turn leads to an increase in forming depth by about 30%. The numerical analysis, performed using the PamStamp 2G System software based on finite element method, was verified experimentally.

    As a continuation of comparison experiments between EUV inspection and visible inspection of defects on EUVL mask blanks, we report on the result of an experiment where the EUV defect inspection tool is used to perform at-wavelength defect counting over 1 cm{sup 2} of EUVL mask blank. Initial EUV inspection found five defects over the scanned area and the subsequent optical scattering inspection was able to detect all of the five defects. Therefore, if there are any defects that are only detectable by EUV inspection, the density is lower than the order of unity per cm2. An upgrade path to substantially increase the overall throughput of the EUV inspection system is also identified in the manuscript.

  8. Formability Analysis of Diode-Laser-Welded Tailored Blanks of Advanced High-Strength Steel Sheets

    Currently, advances due to tailored blanking can be enhanced by the development of new grades of advanced high-strength steels (HSSs), for the further weight reduction and structural improvement of automotive components. In the present work, diode laser welds of three different grades of advanced high-strength dual-phase (DP) steel sheets (with tensile strengths of 980, 800, and 450 MPa) to high-strength low-alloy (HSLA) material were fabricated by applying the proper welding parameters. Formability in terms of Hecker’s limiting dome height (LDH), the strain distribution on the hemispherical dome surface, the weld line movement during deformation, and the load-bearing capacity during the stretch forming of these different laser-welded blanks were compared. Finite element (FE) analysis of the LDH tests of both the parent metals and laser-welded blanks was done using the commercially available software package LS-DYNA (Livermore Software Technology Corporation, Livermore, CA); the results compared well with the experimental data. It was also found that the LDH was not affected by the soft zone or weld zone properties; it decreased, however, with an increase in a nondimensional parameter, the “strength ratio” (SR). The weld line movement during stretch forming is an indication of nonuniform deformation resulting in a decrease in the LDH. In all the dissimilar weldments, fracture took place on the HSLA side, but the fracture location shifted to near the weld line (at the pole) in tailor-welded blanks (TWBs) of a higher strength ratio.

    We present the Cone of Darkness, an application to automatically configure blank-sky positions for a series of stacked, wide-field observations, such as those carried out by the SAMI instrument on the Anglo-Australian Telescope (AAT). The Sydney-AAO Multi-object Integral field spectrograph (SAMI) uses a plug-plate to mount its $13 \\times 61$ core imaging fibre bundles (hexabundles) in the optical plane at the telescope's prime focus. To make the most efficient use of each plug-plate, several observing fields are typically stacked to produce a single plate. When choosing blank-sky positions for the observations it is most effective to select these such that one set of 26 holes gives valid sky positions for all fields on the plate. However, when carried out manually this selection process is tedious and includes a significant risk of error. The Cone of Darkness software aims to provide uniform blank-sky position coverage over the field of observation, within the limits set by the distribution of target position...

  14. Predetermined flake production at the Lower/Middle Paleolithic boundary: Yabrudian scraper-blank technology.

    Directory of Open Access Journals (Sweden)

    Ron Shimelmitz

    Full Text Available While predetermined débitage technologies are recognized beginning with the middle Acheulian, the Middle Paleolithic is usually associated with a sharp increase in their use. A study of scraper-blank technology from three Yabrudian assemblages retrieved from the early part of the Acheulo-Yabrudian complex of Tabun Cave (ca. 415-320 kyr demonstrates a calculated and preplanned production, even if it does not show the same complexity and elaboration as in the Levallois technology. These scraper dominated assemblages show an organization of production based on an intensive use of predetermination blank technology already in place at the end of the Lower Paleolithic of the Levant. These results provide a novel perspective on the differences and similarities between the Lower and Middle Paleolithic industries. We suggest that there was a change in the paradigm in the way hominins exploited stone tools: in many Middle Paleolithic assemblages the potential of the stone tools for hafting was a central feature, in the Lower Paleolithic ergonometric considerations of manual prehension were central to the design of blanks and tools.

    2017-07-01

    Atrial undersensing despite normal atrial lead parameters and high amplitude electrograms has been described in adult patients as a consequence of atrial amplifier saturation. Repetitive inputs cause amplifier ringing and undersensing occurs as a consequence of quiet timer blanking. High amplitude ventricular electrograms can also result in atrial blanking secondary to cross-chamber effect. This has not been described in pediatric patients or epicardial pacing systems and specific risk factors are not known. We describe five cases of atrial undersensing in pediatric and congenital heart disease patients with epicardial dual-chamber systems and high ventricular lead outputs. This was a retrospective cohort study of all patients with dual-chamber pacing systems cared for at the Heart Institute at Children's Hospital Colorado. Five cases of atrial undersensing with normal atrial lead parameters were found. All were epicardial systems with acceptable lead parameters at implantation and Medtronic (Medtronic, Inc., Minneapolis, MN, USA) generators with unipolar leads. Ventricular pacing outputs were elevated at presentation, median 5.5 V (5-7.5). Presenting symptoms were exercise intolerance (four) and detection on routine monitoring (one). Successful interventions included reduction in ventricular lead pacing output (one), programming of rate response (two), and implantation of an alternative generator manufacturer (two). Atrial undersensing secondary to amplifier ringing and quiet timer blanking is an uncommon presentation but may be clinically important in patients with unipolar epicardial atrial leads and high pacing outputs from ventricular leads. © 2017 Wiley Periodicals, Inc.

    The importance of advanced e-beam writing system and chemically amplified resist (CAR) coated blank is increasing gradually in high-end grade photomask manufacture according to CD embodiment of 90 nm and beyond technology node requiring because of the shrinkage of design rule in the semiconductor industry. However, many studies have been reported that CAR has several troubles and especially, CAR sensitivity change is occurred by airborne molecular contamination (AMC). So, the storage life of CAR coated blank is shortened. This problem may cause the difficulty of high-end grade photomask manufacture because it is hard to secure stable mean to target (MTT) and CD uniformity by sensitivity change, T-top profile and footing profile. Therefore, the purpose of this paper is to investigate the storage life extension for high performance CAR coated blank through improvement of the packing materials. Firstly, a variety of packing materials were collected and the selected packing materials were analyzed by Automatic Thermal Desorption Gas Chromatograph/Mass Spectrometer (ATD GC/MS) and Ion Chromatograph (IC) to examine AMC generated from the packing materials. As a result, molecular condensables such as alcohols, hydrocarbons and fatty acids were detected and molecular acids and molecular bases those are NH4+, Cl-, NOx- and SOx- were also detected from the packing materials, respectively. From the above results, we selected the best packing materials which generated the least AMC and the worst packing materials which generated the most AMC. Additionally, we verified photomask process with CAR coated blanks which were packed with those packing materials with post coating delay (PCD) by 50 kV e-beam writing system. In consequence, dose to clear (DTC) showed 4.6 μC/cm2 at 0 day PCD for both of the best and the worst packing materials of CAR coated blank. After 90 days PCD, DTC variation was only 0.4 μC/cm2 for the best packing materials, but DTC variation of 4.0 μC/cm2

    Vocational rehabilitation is by definition a multidisciplinary intervention in a process linked to the facilitation of return to work or to the prevention of loss of the work. Clinical staff in contact with a person who has lost his job (general practitioner, specialized physician) must promote vocational rehabilitation. Medical rehabilitation for those with disabilities, whether new or old, has to be followed without delay by vocational rehabilitation. It is even better if these two intertwined processes are overlapping. They involve many professionals including physiotherapists, occupational therapists, psychologists, vocational trainers, job counsellors, teachers, case-managers, job placement agencies. Vocational rehabilitation has a financial cost, borne by many state organizations (security, social system, social affairs) as well as by employers and private insurances, which are in case of accident, concerned by this process. However, the evidence suggests that this is recouped 2- to 10-fold as suggested by the British Society of Rehabilitation Medicine.

    Metal-polymer-metal sandwich plates are widely used in the automotive and aerospace industry. As for different applications the sandwich plates can be divided into two types. They are sound-damping laminates with a polymer core much thinner than the metallic faces and low-density laminates with a core thickness of approximately 40-60% of the total thickness. One frequent process step in production of parts made of these plates is the blanking process whose hereditary effects draw the limits of further forming stages or service performance and life; e.g. the failure of the adhesive in the thermoplastic polymer interface affects the sound-damping efficiency intensively. With this motivation, we present FE simulation of an axi-symmetric blanking process of steel/polyethylene/steel sound-damping laminates. The mechanical behavior of the metallic layers was characterized by finite strain rate independent elasto-plasticity where progressive material deterioration and fracture are given account for using continuum damage mechanics (CDM). This material model is made accessible via implementations as VUMAT subroutines for ABAQUS/Explicit. Possible failure of the thermoplastic polymer which may lead to delamination of the metallic layers is modeled using ABAQUS built-in cohesive zone elements. The results show that existing intended and unintended failure modes, e.g. blanking of the metallic and thermoplastic polymer constituents as well as failure of polymer layer under shear and compression, can be effectively studied with the proposed framework for process enhancement. As a future work, a damage coupled nonlinear visco-elastic constitutive model will be devised for the simulation of the thermoplastic layer in low-density laminates.

    Because the realization of defect-free Extreme Ultra-violet Lithography (EUVL) mask blanks is uncertain, the defect mitigation techniques are becoming quite important. One mitigation technique, "Pattern shift", is a technique that places a device pattern to cover multilayer (ML) defects underneath the absorber pattern in such a way that the ML defects are not printed onto wafers. This mitigation method requires the defect coordinate accuracy of down to tens of nanometers. Consequently, there is a strong demand for a Blank Inspection tool that is capable of providing such defect coordinate accuracy. To meet such requirement, we have started to develop a high accuracy defect locating function as an optional feature to our EUV Actinic Blank Inspection (ABI) system which is currently being developed aiming at HVM hp16 nm-11 nm node. Since a 26x Schwarzschild optics is used in this inspection tool, it is quite difficult to pinpoint defect location with high accuracy. Therefore we have decided to realize a high magnification review optics of 600x or higher by adding two mirrors to the Schwarzschild optics. One of the additional two mirrors is retractable so that the magnification can be switched according to the purpose of inspections. The high magnification review mode locates defect coordinates accurately with respect to the fiducial position. We set the accuracy target at 20 nm so that the mitigation technique can be implemented successfully. The optical configuration proposed in this paper allows both a high speed inspection for HVM and a high accuracy defect locating function to be achieved on one inspection system.

    A comparison of welding techniques was performed to determine the most effective method for producing aluminum tailor-welded blanks for high volume automotive applications. Aluminum sheet was joined with an emphasis on post weld formability, surface quality and weld speed. Comparative results from several laser based welding techniques along with friction stir welding are presented. The results of this study demonstrate a quantitative comparison of weld methodologies in preparing tailor-welded aluminum stampings for high volume production in the automotive industry. Evaluation of nearly a dozen welding variations ultimately led to down selecting a single process based on post-weld quality and performance.

    Full Text Available Problem statement: Sheet metal extrusion is a process in which the punch penetrates one surface of the sheet metal material to cause it to extrude and flow toward the outlet of the die. Therefore, the process can invent different thickness of sheet metal work piece. From these advantages on the sheet metal extrusion, nowadays, it is generally used in many manufacturing of industrial elements fields. The Sheet Metal Extrusions in Fine Blanking (SME-FB advantages, over a conventional extrusion, are possible due to a blank holder force, a counterpunch force and a large die radius. However, the selection on those parameter values affects on the material flow and the surface quality on the extrusion parts also. Namely, it causes the crack surface and shrinkage failure which are the general problems in the SME-FB. Approach: Objective of this research was to study the effect of die radius on the SME-FB surface which investigated the formation of the failure defection with respect to the several die radiuses by using the Finite Element Method (FEM. Results: From the results, it indicated that applying the small die radius caused the material flow difficult resulting in the decreasing of smooth surface. Vice versa, in the case of large die radius, the material flow easy is resulting in the increasing of smooth surface. Conclusion: The FEM simulation results of a larger die radius will cause the residual stress at work piece.

    AZ31 magnesium alloy sheet with good shape and formability is fabricated by warm cross rolling. Uniaxial tensile tests are conducted using a Gleeble 3500 thermal - mechanical simulator, and the mechanical properties of AZ31 magnesium alloy sheet are analyzed. A warm deep drawing process of square part is also simulated by the finite element method. The influences of blank holder force on the formability are numerically investigated. A double-action hydraulic press that can realize adjustable blank holder forces is developed and its working principle and control system are introduced. Some warm deep drawing experiments of square parts of AZ31 magnesium alloy sheet are also performed. Different variation schemes of the blank holder force with the stroke of the punch are tested, and the experiment results are compared. Results show that the suitable blank holder force variation scheme is a ladder curve with the punch stroke. Adopting the variable blank holder force technique can improve 13.2% of the drawing depth of square parts of AZ31 magnesium alloy sheet.

    The effect of temperature distribution on warm forming performance was investigated for 5083-O (Al-Mg) sheet metal blanks. Combined isothermal/non-isothermal FEA with design of experiments tools were used to predict appropriate warm forming temperature conditions for deep drawing and two-dimensional stamping cases. In the investigated temperature range of 25-250 ℃,the formability of Al-5083 alloy is found to be greatly dependent on the temperature distribution of the die and punch. To achieve increased degrees of forming, different temperature levels should be assigned to the corner and body of the die and punch. And the optimal temperature distributions for warm deep drawing and warm two-dimensional stamping are not identical.

    The availability of defect-free masks remains one of the key challenges for inserting extreme ultraviolet lithography (EUVL) into high volume manufacturing. yet link data is available for understanding native defects on real masks. In this paper, a full-field EUV mask is fabricated to investigate the printability of various defects on the mask. The printability of defects and identification of their source from mask fabrication to handling were studied using wafer inspection. The printable blank defect density excluding particles and patterns is 0.63 cm{sup 2}. Mask inspection is shown to have better sensitivity than wafer inspection. The sensitivity of wafer inspection must be improved using through-focus analysis and a different wafer stack.

    In order to continuously analyze the whole fine-blanking process, from the beginning of the operation up to the total rupture of the sheet-metal, without computational divergence, a 3-D rigid visco-plastic finite-element method based on Gurson void model was developed. The void volume fraction was introduced into the finite element method to document the ductile fracture of the sheet-metal. A formulation of variation of the rigid visco-plastic material was presented according to the virtual work theory in which both the effects of equivalent stress and hydrostatic pressure in the deformation process were considered. The crack initiation of the sheet was predicted and the crack propagation was geometrically fulfilled in the simulation by separating the nodes according to the stress state. Furthermore, the influences of different state-variables on the deformation process were also studied.

    In his short story collection Lost in the Funhouse, John Barth attempts to deal with the existential plights that fictional writing and human beings are faced with.“Title”, the most postmodern story in the collection, centers on the issue of“filling in the blank,”in which Barth leads readers to solve the problem and create the story with him. To examine Barth’s postmodern ex-periment in“Title”, this paper mainly focuses on the following three questions:what is the“blank”? How to fill in it? Why to fill in it in that way? By answering them, we may see how Barth reconciles the conflict between the urgency of“filling in the blank”and the failure of filling them.

    In the present work, tailor friction stir welded blanks (TFSWBs) were fabricated successfully using 2.0-mm-thick AA5754-H22 and AA5052-H32 sheet metals with optimized tool design and process parameters. Taguchi L9 orthogonal array has been used to design the friction stir welding experiments, and the Grey relational analysis has been applied for the multi objective optimization in order to maximize the weld strength and total elongation reducing the surface roughness and energy consumption. The formability of the TFSWBs and parent materials was evaluated and compared in terms of limiting drawing ratio (LDR) using a conventional circular die. It was found that the formability of the TFSWBs was comparable with that of both the parent materials without failure in the weldment. A modified conical tractrix die (MCTD) was proposed to enhance the LDR of the TFSWBs. It was found that the formability was improved by 27% using the MCTD.

    2005-01-01

    The process of the neck spinning of oblique tubes is simulated by means of the 3D elastic-plastic finite element software, MSC. MARC. The dynamic boundary and contact problems in simulation are solved. The characteristics of the metal flowing, the distributions of the stress and strain, the possible defects and areas during spinning are obtained. The influence of the nominal reduction of the blank radius per path on the metal flowing and deformation is also researched theoretically and experimentally. It shows that the nominal reduction of the blank radius per path has great influence on the neck spinning process of oblique tubes. A reasonable nominal reduction of the blank radius per path is very important to guarantee the proceeding of the spinning process and to obtain a sound products.

    `May you live in interesting times' - old Chinese curse. First, many thanks to John Avison, the retiring Honorary Editor, for his hard work over the last five years, and the steady development in style and content under his stewardship. I can only hope to live up to the standards that he set. The next five years will take us into a new millenium, an event preceded - in England and Wales at least - by a period of stability, reflection and consolidation in education. Or so we are told - but whether such a self-denying ordinance will actually be maintained by the Government both before and after an election in 1997 remains to be seen. Nevertheless, we shall be thankful for any mercies, however small, that permit forward thinking rather than instant response. One of the things that readers of a journal called Physics Education should be thinking about is the continued decline in the numbers of students studying physics post-16. This is not a purely local phenomenon; most European countries are finding a similar decline. There are exceptions, of course: in Scotland numbers studying physics for Highers are increasing. Is such a decline a good thing or a bad thing? Only a minority of post-16 physics students go on to use the bulk of what they have learned in further studies or vocations. Does a knowledge and understanding of physics contribute to the mental well-being and cultural level - let alone material comfort - of any except those who use physics professionally? Is physics defensible as a contribution to the mental armoury of the educated citizen - compared with chemistry, biology - or Latin, say? Or should one rephrase that last question as `Is physics as we teach it today defensible...?' Such questions, and many others no doubt, may well be in the mind of the new Curriculum Officer appointed by the Institute of Physics `to engage in a wide-ranging consultation throughout the entire physics community on the nature and style of post-16 physics programmes, with a

  17. Towards automatic recognition of irregular, short-open answers in Fill-in-the-blank tests

    Full Text Available Assessment of student knowledge in Learning Management Systems such as Moodle is mostly conducted using close-ended questions (e.g. multiple-choice whose answers are straightforward to grade without human intervention. FILL-IN-THE-BLANK tests are usually more challenging since they require test-takers to recall concepts and associations not available in the statement of the question itself (no choices or hints are given. Automatic assessment of the latter currently requires the test-taker to give a verbatim answer, that is, free of spelling or typographical mistakes. In this paper, we consider an adapted version of a classical text-matching algorithm that may prevent wrong grading in automatic assessment of FILL-IN-THE-BLANK questions whenever irregular (similar but not exact answers occur due to such types of error. The technique was tested in two scenarios. In the first scenario, misspelled single-word answers to an Internet security questionnaire were correctly recognized within a two letter editing tolerance (achieving 99 % accuracy. The second scenario involved short-open answers to computer programming quizzes (i.e. small blocks of code requiring a structure that conforms to the syntactic rules of the programming language. Twenty-one real-world answers written up by students, taking a computer programming course, were assessed by the method. This assessment addressed the lack of precision in terms of programmer-style artifacts (such as unfamiliar variable or function nomenclature and uses an admissible tolerance of up to 20 % letter-level typos. These scores were satisfactory corroborated by a human expert. Additional findings and potential enhancements to the technique are also discussed.

    Satya Suresh V. V., N.; Regalla, Srinivasa Prakash; Ratna Sudheer, G.

    2016-10-01

    This work relates to warm forming of a tailor welded blank (TWB) where in two or more material blanks are welded together and subjected to localized heating before forming to obtain a desired square cup shape. A novel method of selective heating is carried out by using a split punch and a die in which the high strength blank material is subjected to localized heating by the hot punch so as to induce tailored properties by selective heating to soften it thus reducing and controlling the movement of the weld line during forming. TWB sheets which has different thickness/strength need selective heating and cooling to control weld line shift. The stronger material is subjected to localized softening and thereby decreasing the flow stress thus allowing the blank material to flow into the die cavity. Care has been taken so that the heat is not transferred to the weaker blank material otherwise it will lead to further weakening of the part. For this, cooling mechanism is provided by circulating ice water/coolant to the weaker part. The present work is aimed at studying the weld line shift of TWB's of two different materials namely IFHS and DP 590. Cracks appeared in the weld during forming for drawing ratios greater than 1.7. From the results it was found that the weld line shift is considerably reduced as compared with the results using a single punch. Also it was noticed that there is considerable increase in cup height. Local softening increased the formability of the high strength blank material.

  2. Introduction of a Quality Management System for Vocational Education and Training in Slovakia

    2013-07-01

    Full Text Available The issue of the quality of vocational education, school, teaching and learning of students should be in the interests of all participants in the education process. The quality of secondary school is the critical element in enhancing the attractiveness of vocational education in Slovakia. Finding an offcial scale that would provide such a information in Slovakia is unfortunately impossible. There is no system for evaluating the quality of vocational education and training (VET at vocational schools. There are no clearly defined criterias, rules or any standards. Speaking of an assessing the level of quality of vocational education on the base of existing outcomes in formal education such as monitoring, final exams, graduation exams is resulting in one-sided evaluation and does not address the systematic coherence and complexivity of this issue. An essential step os to create a functional system of evaluation of VET in Slovakia. The article describes importance of VET which can play a central role in preparing young people for work, developing the skills of adults and responding to the labour market needs of the economy and presents the project Model of the quality evaluation of vocational education and training at secondary vocational schools in Slovakia that is currently ongoing on many secondary vocational schools in western Slovakia and Austria. The aim of the project is to develop and apply an open, flexible and adaptable quality management system. The article not only presents indicators for evaluation but also the way how can be evaluated each of them. The effort of this project is also to create specialized portal with support services that provide transparent, clear and specific information from this area of interest. The introduction of the evaluation framework, the selection of indicators that take established criteria into consideration and assembling of the scale is therefore more than relevant and required

  3. Strategies for Translating Vocative Texts

    Olga COJOCARU

    2014-12-01

    Full Text Available The paper deals with the linguistic and cultural elements of vocative texts and the techniques used in translating them by giving some examples of texts that are typically vocative (i.e. advertisements and instructions for use. Semantic and communicative strategies are popular in translation studies and each of them has its own advantages and disadvantages in translating vocative texts. The advantage of semantic translation is that it takes more account of the aesthetic value of the SL text, while communicative translation attempts to render the exact contextual meaning of the original text in such a way that both content and language are readily acceptable and comprehensible to the readership. Focus is laid on the strategies used in translating vocative texts, strategies that highlight and introduce a cultural context to the target audience, in order to achieve their overall purpose, that is to sell or persuade the reader to behave in a certain way. Thus, in order to do that, a number of advertisements from the field of cosmetics industry and electronic gadgets were selected for analysis. The aim is to gather insights into vocative text translation and to create new perspectives on this field of research, now considered a process of innovation and diversion, especially in areas as important as economy and marketing.

    The algorithm is divided into two steps. The first step pre-locates the blank by aligning its centre of gravity and approximate normal vector with those of destination surfaces, with largest overlap of projections of two objects on a plane perpendicular to the normal vector. The second step is optimizing an objective function by means of gradient-simulated annealing algorithm to get the best matching of a set of distributed points on the blank and destination surfaces. An example for machining hydroelectric turbine blades is given to verify the effectiveness of algorithm.

  5. NUMERICAL METHOD FOR PREDICTION OF NET-SHAPED BLANK IN MULTI-POINT FORMING OF SHEET METAL

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    A new numerical method to predict the initial blank geometry from the desired objective shape of parts is pre-sented. Based on the conditions that the deformations in material are most evenly distributed and that the volume remainsconstant, a positive definite functional for blank design is constructed. The functional is minimized by an iterative schemeof finite element, and then the optimal initial configuration is obtained. The method is easy and expedient to use. The re-sults of numerical simulation of forming process and multi-point forming experiments for sheet metal demonstrate thatgood precision is achieved by the proposed method.

    2014-08-01

    Full Text Available The experience of many countries with a well-educated workforce highlights the important role of vocational counselling services for advantageous youth professional orientation. Researchers manifest in their turn, a growing interest to study the role of vocational counselling, from the perspective of increasing the efficiency of investment in education and strengthening the capacity of enterprises to meet the challenges of the knowledge economy. In Romania, high school students have access to career guidance services, but there is little information on the extent to which they use or how useful they consider these services. Many times, there is a social conformism among high school graduates, which determines them to choose professions valued at a certain moment, without making a personal judgment. The aim of this paper is to analyse, as a good practice, the role of high school graduate vocational counselling in developing professional skills, in order to help them make the right career decision. In order to monitor the high school students` opinions on the vocational guidance and their perceptions of the integration in the labour market, a market research study has been conducted. This is a survey conducted on a sample of 2,364 high school students in their final year of study (twelve grade. The research has shown that a reduced percentage of the interviewed high school students have knowledge about the vocational guidance activity. From those who have used these services, most of them were satisfied. The study also highlighted the fact that the most important criteria for getting a job are the skills acquired during studies.

    2014-07-01

    The Daniel K. Inouye Solar Telescope (DKIST, formerly the Advanced Technology Solar Telescope, ATST) will be the most powerful solar telescope in the world. It is currently being built by the Association of Universities for Research in Astronomy (AURA) in a height of 3000 m above sea level on the mountain Haleakala of Maui, Hawaii. The primary mirror blank of diameter 4.26 m is made of the extremely low thermal expansion glass ceramic ZERODUR® of SCHOTT AG Advanced Optics. The DKIST primary mirror design is extremely challenging. With a mirror thickness of only 78 to 85 mm it is the smallest thickness ever machined on a mirror of 4.26 m in diameter. Additionally the glassy ZERODUR® casting is one of the largest in size ever produced for a 4 m class ZERODUR® mirror blank. The off axis aspherical mirror surface required sophisticated grinding procedures to achieve the specified geometrical tolerance. The small thickness of about 80 mm required special measures during processing, lifting and transport. Additionally acid etch treatment was applied to the convex back-surface and the conical shaped outer diameter surface to improve the strength of the blank. This paper reports on the challenging tasks and the achievements on the material property and dimensional specification parameter during the production of the 4.26 m ZERODUR® primary mirror blank for AURA.

    Bacterially derived triple-helical, collagen-like proteins are attractive as potential biomedical materials. The collagen-like domain of the Scl2 protein from S. pyogenes lacks any specific binding sites for mammalian cells yet possesses the inherent structural integrity of the collagen triple-helix of animal collagens. It can, therefore, be considered as a structurally-stable "blank slate" into which various defined, biological sequences, derived from animal collagens, can be added by substitutions or insertions, to enable production of novel designed materials to fit specific functional requirements. In the present study, we have used site directed mutagenesis to substitute two functional sequences, one for heparin binding and the other for integrin binding, into different locations in the triple-helical structure. This provided three new constructs, two containing the single substitutions and one containing both substitutions. The stability of these constructs was marginally reduced when compared to the unmodified sequence. When compared to the unmodified bacterial collagen, both the modified collagens that contain the heparin binding site showed marked binding of fluorescently labeled heparin. Similarly, the modified collagens from both constructs containing the integrin binding site showed significant adhesion of L929 cells that are known to possess the appropriate integrin receptor. C2C12 cells that lack any appropriate integrins did not bind. These data show that bacterial collagen-like sequences can be modified to act like natural extracellular matrix collagens by inserting one or more unique biological domains with defined function.

    2016-03-01

    Deformation characteristic of centrifugal casting 25Mn steel was investigated by compression tests, and then processing maps were established. According to the deformation parameters identified from the established processing maps and hot ring rolling (HRR) process, the industrial test for the 25Mn ring blank was performed. Optical microscope (OM) and electron backscatter diffraction (EBSD) techniques were used for detecting grain boundary features and textures of deformation structures. The morphologies and mechanisms of tensile and impact fracture were revealed. The results show that softening effect plays a dominant role in higher temperatures of 1050-1150 °C and strain rates lower than 0.1 s-1. The average grain size of the rolled 25Mn ring is about 28 μm, but the grains are more coarse and inhomogeneous on the middle layer than that on rest of the areas. The texture on the outer layer is characterized by strong {110} and weak {112} , followed by {001} and {001} on the inner layer and {110} on the center layer, which is mainly associated with the shear deformation. The rolled ring with precise geometrical dimensions and sound mechanical properties is fabricated by HRR. Tensile fracture is composed of clear river-shaped pattern and a little dimple near the inner layer and outer layer, and the fracture mechanism is mainly quasi-cleavage fracture, accompanied by dimple fracture. The morphologies of impact fracture consist of tear ridge and cleavage platform.

  20. Impact of EUVL mask surface roughness on an actinic blank inspection image and a wafer image

    Science.gov (United States)

    Yamane, Takeshi; Terasawa, Tsuneo

    2012-11-01

    An impact of EUVL mask surface roughness on actinic inspection was studied. The background level (BGL) of an actinic inspection image is caused by the light scattered from the mask blank surface roughness. The BGL is found to be proportional to the square of the mask surface roughness measured by AFM. By using this proportionality coefficient, a global distribution of the surface roughness can be obtained at the same time while inspection a mask. On the other hand, any local variation of BGL indicates variation of the mask surface roughness at each pixel. Assuming that the roughness at a center pixel is 0.15 nm rms (SEMI standard specification) and those at the surrounding pixels are 0.1 nm rms, the signal intensity at the center pixel is found to be approximately the same as that of a 1.2 nm-high and 40 nm-wide programmed defect. In that case, CD error on a wafer image due to the reflectivity loss by the roughness is found to be not critical. This means that the local roughness should be less than 0.15 nm rms, and that the inspection system can detect such a local variation of the roughness with 100 % probability.

    2011-11-01

    We had developed an actinic full-field inspection system to detect multilayer phase-defects with dark field imaging. Regarding the actinic inspection of native defects, the influence of the defect's surface dimension and multilayer structure, on the intensity-signal obtained from the inspection was analyzed. Three mask blanks were inspected from which 55 defects, observed with AFM and SEM, were classified as amplitude-defects or phase-defects. The surface dimensions and SEVDs (sphere equivalent volume diameters) of the defects were measured with the AFM. In the case where their SEVDs were same as of the programmed phase-defects, they were found to produce stronger intensitysignals in comparison to the ones from the programmed phase-defects. Cross-sectional multilayer structures of two native phase-defects were observed with TEM, and those defects formed non-conformal structures in the multilayer. This result means that most of the native phase-defects tend to form a non-conformal structure, and can make large impact on the wafer image in comparison to the ones from a conformal structure. Besides phase-defects, the actinic inspection also detected amplitude-defects. Although the sensitivities of the amplitude-defects were found to be lower than those of the phase-defects, an amplitude-defect higher than 30 nm could be detected with high probability.

    2006-06-01

    Ultra-Low Expansion (ULE ®) glass has been and continues to be a significant material for astronomical applications. With a nominal composition of 7 wt. %TiO II in SiO II, Corning Code 7972 ULE ® has a mean room temperature coefficient of thermal expansion (CTE) of 0 +/- 30 ppb/°C with a typical CTE range of less than 15 ppb/°C, properties vital to the manufacture of high resolution optics requiring extreme thermal stability. Combined with lightweighting techniques developed at Corning during the past 30 years, ULE ® has been successfully employed for numerous monolithic and lightweight mirror applications including the 2.4 meter Hubble Space Telescope lightweight primary mirror, the Airborne Laser (ABL) primary mirrors, and most recently the Discovery Channel Telescope 4 meter mirror blank. ULE ® maintains its strong candidacy for future ELT applications. Recent challenges in mirror surface specifications and the development of alternative material choices calls for a comparison with ULE ®. The objective of this article is to review ULE ® properties and manufacturing capabilities, and to compare relevant material properties to those of alternative material options, thus allowing designers to properly execute material selection. Finally, recent development efforts directed toward improving ULE ® will be discussed.

    Optical diagnostics, such as VISAR (Velocity Interferometer System for Any Reflector) or SOP (Streaked Optical Pyrometry), have become essential in shock timing experiments. Their high precision allows for accurate measurements of shock velocities, chronometry, and brightness temperature. However, in some instances, these measurements can be compromised. In planar shock coalescence experiments recently performed at the LULI facility [Baton et al., Phys. Rev. Lett. 108, 195002 (2012)], VISAR signal loss was observed. In these experiments, a strong shock launched by a high-intensity spike catches up with a previously shock launched by an earlier, low-intensity beam. The disappearance of the VISAR signal is attributed to a preheating of the coronal plasma by x-rays generated by the high intensity spike. The signal does not disappear if the high-intensity spike starts after VISAR probe beam begins to reflect off of the first shock. The VISAR diagnostic, modeled using an assessment of the optical index in quartz, compares favorably to experimental results. This provides evidence that x-ray preheating can cause blanking of the VISAR signal in quartz.

    Extreme ultraviolet (EUV) multilayer defects (phase defects) are a defect type unique to extreme ultraviolet lithography (EUVL) masks. A manufacturable inspection capability for these defects is key to the success of EUV lithography. Simulations of EUV scattering from multilayer defects suggest that defect printability is related to the phase error induced by the defect, which is in turn strongly coupled to the size of a multilayer surface protrusion or intrusion. We can adopt a strategy of measuring the multilayer surface to detect phase defects. During the past year a working group composed of members of Intel Corporation, Lawrence Berkeley and Lawrence Livermore National Laboratories, and International Sematech searched for a commercial tool for EUVL mask substrate and blank inspection. This working group established the tool requirements, methodologies for tool evaluation, collected data and recommended a supplier for further development with International Sematech. We collected data from several vendors and found that a multibeam confocal inspection (MCI) system had a capability significantly better than the tools used today. We will present our strategy, requirements, methodologies and results. We will discuss in detail our unique programmed substrate and multilayer defect masks used to support the tool selection, including their actinic characterization. We will present data that quantifies the inspection capability of the MCI system.

    The resources that the students entered the vocational and technical school are mostly those who failed in the admissions examination of the ordinary high schools. The grades of their entrance exam are uneven, a majority of the students' English is relatively poor when they entered the school, their foundation is weak when they were in the junior high school, some even a blank, so they don' t really understand English classes, and they will do something which has nothing to do with the study in the classroom, such as sleeping, not concentrating, reading other books, and so on. At the same time, teachers still follow the old model that teachers only teach book knowledge to students, while ignoring the comprehensive ability of speaking and writing. As a result, the interests of learning English generally become low, and the basic language application ability is deficient .When they graduated and then went to the society, they didn't take the advantages of their professional skill. Their own development will be disadvantageous in the future. In order to improve the quality of teaching English in the vocational and technical school, the author puts forward to several suggestions.%进入职业技术学校学习的生源,大都是普通高中的“落榜者”。学生入学成绩参差不齐,大部分学生入学英语成绩比较差,很多学生初中时英语基础就薄弱,甚至大面积空白,以致现在听不懂英语课,在课堂上做一些与学习无关的事,思想开小差、看其他书籍等等。同时在中职英语课堂教学方面,教师仍沿袭着单纯灌输书本知识,而忽略学生听说读写综合能力培养的旧有模式,致使学生的英语学习兴趣普遍不高,语言基本应用能力匮乏,毕业走上工作岗位后,发挥不出”一技之长”的特点优势。为了提高中职英语教学质量,提出了几点建议。

    1983-01-01

    The relationship between interest in management roles and personality, demographic, and career background characteristics of 122 female nurses was investigated. The study tested the proposition that women in nursing seek roles within the profession that permit the expression of their personalities. The subjects, first-quarter master's degree students, were classified into management or non-management groups, based upon their scores on the business management scale of the Strong-Campbell Interest Inventory (SCII). Results of a multivariate analysis of variance (MANOVA) for unequal N's showed significant group differences on seven of the 11 scales of the Vocational Preference Inventory (VPI). Findings indicated that those who exhibited managerial interests were more practical-minded, sociable, conforming, dominant, expressive, and had more occupational interests than those who did not demonstrate such interest. Women lacking managerial interests showed a greater preference for "feminine," low-status occupations. No significant group differences were found on any of the 19 demographic and career background variables.

    2004-01-01

    In this paper, the effect of variable Blank-holder forces (VBHF) on the strain path during sheet metal forming has been investigated by numerical simulation and experiments. The formability of select aluminum alloy sheet was evaluated by theory prediction of forming limit curve based on the M-K method. The effect of different VBHF on the formability was presented. In order to verify the predictions of strain path, experiments are being carried out using a recently-built multi-points variable blank-holder forces hydraulic press. The results show that large side BHF with small comer BHF during rectangular box deep drawing can improve the formability of the selected aluminum alloy sheet

  7. Reforming Vocational Education and Training

    DEFF Research Database (Denmark)

    Friche, Nanna; Kondrup, Sissel

    The systems of vocational education and training are facing a number of challenges in many European countries. The share of young people who are neither employed, nor in education or training (NEET) is still higher for graduates from upper secondary VET than from upper secondary general programmes....... Students who enter vocational programmes are less likely to graduate than those who are enrolled in general programmes. Moreover, they are nearly five times less likely to enrol in further education than graduates from general secondary schools with similar proficiency in literacy (OECD 2015). These trends...... means that the challenges are twofold. First, the VET systems are required to offer double qualifications, which give access not only to skilled employment, but also to higher education (Deissinger et.al 2013). Secondly, the VET systems are met by diverse demands to be social inclusive and exclusive...

  8. Effect of Variable Blank Holder Force on Rectangular Box Drawing Process of Hot-galvanized Sheet Steel

    Institute of Scientific and Technical Information of China (English)

    Qunqiang FU; Wei ZHU; Zhiliang ZHANG; Hongying GONG

    2005-01-01

    At first, a series of finite element method (FEM) simulation tests were used to find the critical forming conditions of hot-galvanized sheet steel during the rectangular box drawing processing when constant blank holder forces were applied. According the test results, the reasonable alteration scope of initial variable blank holder force (VBHF) wasas 1.9~2.3 T. Then, based on the test productions of blank holder force, 12 typical VBHF curves were applied to perform the simulation tests by the simulation software of DYNAFORM. The simulation test results showed that VBHF had great effects on drawing formability of hot-galvanized sheet steel during the rectangular box drawing.However, the different VBHF curves were applied to control the whole drawing and it would get great different effects. At the same tine, the VBHF had great effects on the maximum thick thinning ratio, but had little effect on the maximum thick incrassation ratio. So, reasonable application of the VBHF would greatly decrease the fractures.When the VBHF profile is taken as curve L, the best effect of drawing formability could be obtained. When curve I is used, contrary effect could be gotten. The other types of curves would cause effects between above two types of VBHF curves. Finally, the actual tests were applied to check the validity of the FEM simulation tests. The results show that the FEM simulation tests are good ways for predicting and optimizing the VBHF.

    Full Text Available The paper considers an experimental evaluation of the influence of a plane periodic circular motion which is transferred to a blank on the intensity of its sawing and quality of its machined surface. Description of a modernized industrial sawing section has been given in the paper. The section is used for sawing various types of specimens (jasper, quartz glass, corundum as under conventional machining conditions so while transferring them a circular motion along a closed path with a shape being like an ellipse. It has been established that in comparison with machining under conventional conditions transfer of such motion to a blank makes it possible significantly (by 2.5-3.9-fold to improve sawing intensity and simultaneously to reduce Ra value of their sawed surfaces by 1.9-3.0-fold. The obtained results have allowed to make a qualitative description of a mechanism which reveals an influence of a blank circular motion on higher intensity of its sawing and quality of the machined surface.

  11. Reconstructing Vocational Education and Training for the 21st Century

    Directory of Open Access Journals (Sweden)

    Terry Hyland

    2014-01-01

    Full Text Available The unfavorable comparisons between English and European vocational education and training (VET systems made in the Wolf Report—and indeed in many national reviews of VET in Britain since the Royal Commission on Technical Education reported in 1884—point toward the low status of vocational pursuits in the United Kingdom compared with that in Continental Europe and elsewhere. In the light of these cultural differences, it is unlikely that structural, funding, or curriculum reforms alone will succeed in enhancing VET provision without corresponding changes in the value foundation of vocational studies. The reconstruction of VET requires a re-orientation of its foundational values if the reforms proposed by Wolf and others are to have any chance of lasting success. By the same token—although European and other national systems have their own peculiar problems—the global policy agenda concerned only with cognitive outcomes expressed as behaviorist skills and competences is, arguably, unlikely to meet the key challenges. A reconstructed model of VET needs to foreground the values, craft, and aesthetic features of vocationalism if the perennial problems are to be dealt with adequately. A reconstruction plan is suggested below, informed and inspired by the concept of “mindfulness”—non-judgmental, present-moment attention, and awareness—drawn from Buddhist contemplative traditions. Mindfulness-based interventions (MBIs in areas such as psychology, psychotherapy, medical science, and education have grown exponentially over the last decade or so, and interesting work is now emerging in relation to the value of mindfulness in workplace training.

The other three  group members (those above 155 points were the ones who had reached the expected vocational maturity.Posttest results showed that two of the group members had not reached the targeted vocational maturity.  One of these students stated that since he would work at the building sector in which his father was working the sessions had not picked up much of his interest and it was observed that he had not attended to two of the group activies. This may be considered as the reason why he did not benefitted from group works.Lack of improvement in other group member's maturity level may be the result of the fact that he will not continue his education after primary school and his reluctance to attend to activities in group sessions. After the implementation of the program, a significant difference was observed between pretest and posttest scores. Mean vocational maturity inventory scores before the program was 145.83 while it increased to 153.25. This finding shows that the study had an important influence on the improvement of vocational maturity by raising group members' vocational maturity inventory scores.

    Research suggests that trajectories toward careers in science, technology, engineering, and mathematics (STEM) emerge early and are influenced by multiple factors. This paper presents a longitudinal study, which uses data from 76 high school students to explore how a student's vocational self-efficacy and interest are related to his or her middle school behavioral and affective engagement. Measures of vocational self-efficacy and interest are drawn from STEM-related scales in CAPAExplore, while measures of middle school performance and engagement in mathematics are drawn from several previously validated automated indicators extracted from logs of student interaction with ASSISTments, an online learning platform. Results indicate that vocational self-efficacy correlates negatively with confusion, but positively with engaged concentration and carelessness. Interest, which also correlates negatively with confusion, correlates positively with correctness and carelessness. Other disengaged behaviors, such as gaming the system, were not correlated with vocational self-efficacy or interest, despite previous studies indicating that they are associated with future college attendance. We discuss implications for these findings, which have the potential to assist educators or counselors in developing strategies to sustain students' interest in STEM-related careers.

This thesis examined undergraduate students at the University of North Texas not majoring in the life sciences interest in genetic concepts through the means of a Likert style survey. ANOVA analysis showed there was variation amongst the interest level in different genetic concepts. In addition age and lecture were also analyzed as contributing factors to students' interest. Both age and lecture were evaluated to see if they contributed to the interest of students in genetic concepts and neither showed statistical significance. The Genetic Interest Assessment (GIA) serves to help mediate the gap between genetic curriculum and students' interest.

    Full Text Available During the last years, one of the most interesting subjects in the automotive industry is the weight reduction of the automobile, and so to diminish the fuel consumption. Among other performances, the use in the body car of materials which have high mechanical resistance must be considered for the weight reduction of the automobile and maintaining high benefits. In this work, it has been studied the utilization of the diode laser for high resistance steel sheets welding, concretely microalloying steels (ZStE, DP "dual phase" and TRIP "transformation induced plasticity". These steels can be employed in "tailored blanks", which are defined as two or more separate pieces of flat material of dissimilar thickness and/or physical properties joined together before forming, to provide superior qualities in the finished stamped part. In this study, the metallographic characterization has been realised in the welding seams; and the mechanical behaviour has been analysed employing the following tests: microhardness, drawing, tensile and fatigue.

    Uno de los puntos de mayor interés para la industria de la automoción, en los últimos años, es la reducción en peso del automóvil y conseguir, con ello, rebajar el consumo de combustible. Disminuir el peso del automóvil y mantener unas elevadas prestaciones implica, entre otras actuaciones, la utilización de materiales en la carrocería que posean una elevada resistencia mecánica. En este trabajo se presenta el estudio de la viabilidad de la utilización del láser de diodo para la soldadura de chapas de acero de alta resistencia; concretamente de aceros ferríticos microaleados (ZStE, DP (dual phase y TRIP (transformation induced plasticity. Todos ellos, son materiales que pueden formar parte de tailored blanks que se definen como piezas constituidas por la unión, mediante soldadura, de chapas de acero de distintas calidades y espesores.

    Tanggaard, Lene

    This presentation poses the question: what conception of the phenomenon of creativity is best suited to the field of vocational education? VET (Vocational Education and Training) aims to prepare people for employment in craft and industry. In this field, there is an ever-growing requirement...... for creativity and innovation. In response, it is my concern that an understanding of creativity be developed with vocational education and training in mind. It is not enough to import models from other areas, where the distinction between ideas and production or creativity and execution is often relatively hazy...... and therefore not well suited for VET comprising production, handcraft and industry. In Europe, vocational education schemes are considered the solid base on which almost all kinds of industry and craft depend.

    Full Text Available Several issues were raised from the study of technical and vocational education: low pay, no career path for their future, unable to get admission to university, and finally technical education and vocational training are perceived to be for school dropouts and special needs students (the disabled (Ahmad Esa , 2010; Ramlee, 1999; Wancott, 2000; Gray, 1997; Stone, 1993; Kang and Bishop, 1986. Although various efforts have been undertaken by several agencies to encourage technical education and vocational training to the public, students and parents still prefer academic education to vocational education. Why does this phenomenon still exist despite the publicity given by many agencies? Do parents, students, teachers and school counselors, and various related parties understand the system of vocational education? Aren’t there sufficient promotion arranged? Aren’t there enough "success stories" of those doing technical education and vocational training brought to light by local media? This qualitative study was conducted in two zones, namely, the north (Kedah and central zone (Selangor, two schools were chosen from each zone; one school in the city (Kajang and one from the rural (Dengkil, which are sufficient to get the views of  parents and teachers. The results showed that there was a positive response from parents and teachers about the work reputation and re-branding of technical education and vocational training. Technical and vocational fields are no longer targeted for weak students; on the other hand this study has shown that parents believe that girls too can become successful mechanics. Now parents and teachers are encouraging students to pursue their field of interest, and no longer judge them based on test results per se to take up tertiary education. The path of technical education and vocational training can be advanced to university level and continued abroad. There are suggestions that opportunity should also be given to

  17. A New Method to Calculate Threshold Values of Ductile Fracture Criteria for Advanced High-Strength Sheet Blanking

    Science.gov (United States)

    Wang, Changsheng; Chen, Jun; Xia, Cedric; Ren, Feng; Chen, Jieshi

    2014-04-01

    A new approach is presented in this paper to calculate the critical threshold value of fracture initiation. It is based on the experimental data for forming limit curves and fracture forming limit curves. The deformation path for finally a fractured material point is assumed as two-stage proportional loading: biaxial loading from the beginning to the onset of incipient necking, followed plane strain deformation within the incipient neck until the final fracture. The fracture threshold value is determined by analytical integration and validated by numerical simulation. Four phenomenological models for ductile fracture are selected in this study, i.e., Brozzo, McClintock, Rice-Tracey, and Oyane models. The threshold value for each model is obtained through best-fitting of experimental data. The results are compared with each other and test data. These fracture criteria are implemented in ABAQUS/EXPLICIT through user subroutine VUMAT to simulate the blanking process of advanced high-strength steels. The simulated fracture surfaces are examined to determine the initiation of ductile fracture during the process, and compared with experimental results for DP780 sheet steel blanking. The comparisons between FE simulated results coupled with different fracture models and experimental one show good agreements on punching edge quality. The study demonstrates that the proposed approach to calculate threshold values of fracture models is efficient and reliable. The results also suggest that the McClintock and Oyane fracture models are more accurate than the Rice-Tracey or Brozzo models in predicting load-stroke curves. However, the predicted blanking edge quality does not have appreciable differences.

    Olsen, Lisa D.; Fram, Miranda S.; Belitz, Kenneth

    2010-01-01

    Trace-element quality-control samples (for example, source-solution blanks, field blanks, and field replicates) were collected as part of a statewide investigation of groundwater quality in California, known as the Priority Basins Project of the Groundwater Ambient Monitoring and Assessment (GAMA) Program. The GAMA Priority Basins Project is being conducted by the U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board (SWRCB) to assess and monitor the quality of groundwater resources used for drinking-water supply and to improve public knowledge of groundwater quality in California. Trace-element field blanks were collected to evaluate potential bias in the corresponding environmental data. Bias in the environmental data could result from contamination in the field during sample collection, from the groundwater coming into contact with contaminants on equipment surfaces or from other sources, or from processing, shipping, or analyzing the samples. Bias affects the interpretation of environmental data, particularly if any constituents are present solely as a result of extrinsic contamination that would have otherwise been absent from the groundwater that was sampled. Field blanks were collected, analyzed, and reviewed to identify and quantify extrinsic contamination bias. Data derived from source-solution blanks and laboratory quality-control samples also were considered in evaluating potential contamination bias. Eighty-six field-blank samples collected from May 2004 to January 2008 were analyzed for the concentrations of 25 trace elements. Results from these field blanks were used to interpret the data for the 816 samples of untreated groundwater collected over the same period. Constituents analyzed were aluminum (Al), antimony (Sb), arsenic (As), barium (Ba), beryllium (Be), boron (B), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), lead (Pb), lithium (Li), manganese (Mn), mercury (Hg), molybdenum

    Full Text Available European Union requires some standards in all areas. Today, the importance of training qualified individuals which holds an important place in the development of countries increases and certain standards are adopted creating common European Union tools in the field of vocational and technical education. In this study, vocational education and training policies system and the standards adopted by the European Union are discussed. Furthermore, this study was accepted as a European Union project in 2010 and the results obtained from the Leonardo Da Vinci Life Learning European Union project called “Web Based Basic Vocational Training” between the years 2010-2012 were presented. Since the partners of these projects are Turkey, Spain and Germany, the structure of vocational education, institutions of public and private vocational education and the diplomas and certificates entitled after these educations are included. As Turkey is on its way to become a European Union member, a number of advices are presented for Turkey to reach its destination about vocational education standards that European Union has aimed. The purpose of the study is not only to be a guide for the young who want to get professional training in the countries that are European Union members or candidates about how and where to have education opportunities but also to give a chance for trainers and training managers, participating in vocational training, so as to glimpse different practices from different countries and compare these practices between the countries of European Union and their countries. The study is also very important as it has the opportunities for training managers to see if their countries' vocational education is close enough to vocational education in European Union.

    2011-08-01

    In order to improve assembly accuracy, automotive body panels have to be fabricated with higher dimensional and surface quality requirements, therefore the die faces should be designed more accurately to consider more relevant factors. In the presented study, we proposed algorithms to realize the following functions: through forming process simulation, the thinning distribution on the deformed blank was extracted as first kind of compensation; through die structural CAE analysis which automatically mapped the boundary contact forces onto the die surfaces from process simulation results, the die deflection was calculated as second kind of compensation. These two quantitative contributions were added together to compensate the die face. The proposed methodologies were programmed and integrated with LS-Dyna and HyperWorks, and also integrated with Autoform and CATIA linear CAE functionalities separately. In addition, a software toolkit to calculate the contacting ratio was also developed to evaluate the effectiveness of die face compensation. The second toolkit developed was verified by an automotive structural part forming die design, through die compensation and geometric optimization, the predicted contact ratio between the die face and formed blank was improved a lot, and the first toolkit was testified by a fender drawing die design. It shows that the die face compensation can be realized and integrated seamlessly between CAD model, process simulation model and die structural CAE model with the help of data I/O tools developed by the authors.

  9. A study on using pre-forming blank in single point incremental forming process by finite element analysis

    Science.gov (United States)

    Abass, K. I.

    2016-11-01

    Single Point Incremental Forming process (SPIF) is a forming technique of sheet material based on layered manufacturing principles. The edges of sheet material are clamped while the forming tool is moved along the tool path. The CNC milling machine is used to manufacturing the product. SPIF involves extensive plastic deformation and the description of the process is more complicated by highly nonlinear boundary conditions, namely contact and frictional effects have been accomplished. However, due to the complex nature of these models, numerical approaches dominated by Finite Element Analysis (FEA) are now in widespread use. The paper presents the data and main results of a study on effect of using preforming blank in SPIF through FEA. The considered SPIF has been studied under certain process conditions referring to the test work piece, tool, etc., applying ANSYS 11. The results show that the simulation model can predict an ideal profile of processing track, the behaviour of contact tool-workpiece, the product accuracy by evaluation its thickness, surface strain and the stress distribution along the deformed blank section during the deformation stages.

    In this work, we investigated factors that influence burr formation for zircaloy-4 sheet used for spacer grids of nuclear fuel roads. Factors we considered are geometric factors of punch. We changed clearance and velocity in order to consider the failure parameters, and we changed shearing angle and corner radius of L-shaped punch in order to consider geometric factors of punch. First, we carried out blanking test with failure parameter of GTN model using L-shaped punch. The tendency of failure parameters and geometric factors that affect burr formation by analyzing sheared edges is investigated. Consequently, geometric factor's influencing on the burr formation is also high as failure parameters. Then, the sheared edges and burr formation with failure parameters and geometric factors is investigated using FE analysis model. As a result of analyzing sheared edges with the variables, we checked geometric factors more affect burr formation than failure parameters. To check the reliability of the FE model, the blanking force and the sheared edges obtained from experiments are compared with the computations considering heat transfer.

    Full Text Available The main purpose of this study is to understand the perception of the image and pride of working in the technical and vocational fields from the perspective of parents and teachers in secondary schools. This study was conducted in two zones, namely North (Kedah and central zone (Selangor. Two schools were chosen from each zone, one from the city (Kajang and the other one from rural (Dengkil, which are sufficient to obtain the views of parents and teachers. Purposive sampling was selected for the focus group discussions in schools with the participation of PTA members, i.e., parents, teachers, career counselors teachers. The results showed that there were two main themes, namely, positive and negative image of technical education and vocational training among parents and teachers. However, the negative image remained resilient among parents and teachers, especially in deciding on career paths in technical and vocational fields. The researcher also identified several new issues, for example, wastage of manpower in the country, among them due to the weak prerequisite set in selecting students in technical and vocational education system; Students who do not meet the Malay Language (Bahasa Melayu prerequisite are unable to continue studying skills at higher certificate level. Students of Islamic studies and Arabic Language, students with academic excellence and girls who are interested in technical education and vocational training should be considered as a highly skilled workforce in the future. Some implications of this study were presented as suggestion in formulating policies to improve the image of technical education and vocational training.

    This article traces the EC vocational training policy historically and describes the discursive alignments which brought the policy from a ‘common vocational training policy' as laid down in Article 128, in the Treaty of Rome to the Lisbon Lifelong Learning strategy. The argument is that vocational...... training has served as a lever for the gradual expansion of the policy field into both general and higher education and for the establishment of a European discourse on Lifelong Learning. In the article, Ball's concept of "policy as discourse" is used to identify the changing spaces of possibility within...... EC vocational training policy (Ball, What is policy?

    Economic development has made a negative impact on the environment. However, our proceedings on public interest action are almost blank, causing many of the cases related to the environmental protection to be rejected by the court for the reason that the prosecutors fail to provide enough evidence. Therefore, we can take the U.S. system of civil action for reference to improve our public interest action while employing proxy litigation. The measures can be included as follows: relax the plaintiff qualifications; establish the necessary lead procedures; invert the responsibility of providing evidence.

  7. Medical sociology as a vocation.

    Science.gov (United States)

    Bosk, Charles L

    2014-12-01

    This article extends Weber's discussion of science as a vocation by applying it to medical sociology. Having used qualitative methods for nearly 40 years to interpret problems of meaning as they arise in the context of health care, I describe how ethnography, in particular, and qualitative inquiry, more generally, may be used as a tool for understanding fundamental questions close to the heart but far from the mind of medical sociology. Such questions overlap with major policy questions such as how do we achieve a higher standard for quality of care and assure the safety of patients. Using my own research, I show how this engagement takes the form of showing how simple narratives of policy change fail to address the complexities of the problems that they are designed to remedy. I also attempt to explain how I balance objectivity with a commitment to creating a more equitable framework for health care. © American Sociological Association 2014.

  8. Blank size dependence of microstructure in radial-axial ring rolling of TA15 titanium alloy by macro-micro FE simulation

    Directory of Open Access Journals (Sweden)

    Guo Lianggang

    2015-01-01

    Full Text Available The blank size, determining the deformation degree and the ratio of axial to radial feed amount of the radial-axial ring rolling process for TA15 titanium alloy, has a strong effect on the grain size and volume fraction of primary α phase, which determine the mechanical properties of the rolled ring. In this paper, a macro-micro 3D-FE model of the radial-axial ring rolling of TA15 titanium alloy has been developed under ABAQUS software. The ring blank transferring from heating furnace to rolling mill, rolling and cooling after rolling during the whole process are considered in the FE model. And multiple blanks with different rolling ratios and ratios of axial to radial feed amount are designed for a desired TA15 titanium alloy ring. Then, the effects of the blank size on the grain size and volume fraction of primary α phase in the rolled ring are investigated by comprehensive FE simulations. Finally, the optimum blank sizes are obtained by evaluating both the volume fraction of primary α phase and the distribution uniformities of grain size and volume fraction of primary α phase.

    1997-12-31

    A mathematical model for a coupled analysis of fluid flow, heat transfer and deformation behavior in the continuously cast beam blank has been developed. The fluid flow, heat transfer and solidification in the mold region were analyzed with 3-dimensional finite difference method (FDM) based on control volume method. A body fitted coordinate system was introduced for the complex geometry of the beam blank. The effects of turbulence and natural convection of molten steel were taken into account in determining the fluid flow in the strand. The thermo-elasto-plastic deformation behavior in the cast strand and the formation of air gap between the solidifying shell and the mold were analyzed by the finite element method (FEM) using the 2-dimensional slice temperature profile calculated by the FDM. The heat flow between the strand and the mold was evaluated by the coupled analysis between the fluid flow-heat transfer analysis and the thermo-elasto-plastic stress analysis. In order to determine the solid fraction in the mushy zone, the microsegregation of solute element was assessed. The effects of fluid flow on the heat transfer, the solidification of steel and the distribution of shell thickness during the casting of the beam blank were simulated. The deformation behavior of the solidifying shell and the possibility of cracking of the strand were also investigated. The recirculating flows were developed in the regions of the web and the flange tip. The impinging of the inlet flow from the nozzle retarded the growing of solidifying shell in the regions of the fillet and the flange. The air gap between the strand and the mold was formed near the region of the corner of the flange tip. At the initial stage of casting, the probability of the surface cracking was high in the regions of the fillet and the flange tip. After the middle stage of casting, the internal cracking was predicted in the regions of the flange tip, and between the fillet and the flange tip. (author) 38

    Full Text Available The paper focuses on socially and historically structured circumstances surrounding and moral problems involved in the pragmatic definition of innovation as 'novelty proven useful by its users'. Contending conceptions and strategies of innovation of the organization of social relations in dialectical social systems are compared and socially and historically contextualized in the so-called 'transition countries' on the new Eastern border of the European Union. The conclusion is that the cited pragmatic definition of innovation may be misused for an apology of morally dubious new ends and means in the narrow interest of particular groups of users, often at the expense and against the interest of a majority of other individuals and social groups.

    Full Text Available This study is aimed to predict the minimum varying blank holder force (VBHF during the punch stroke, in order to eliminate wrinkle on cup deep drawing product. The slab method was used to develop mathematical modeling of the minimum VBHF base on a gap limit and unbending energy. The mathematical modeling has been validated to FE simulations for the prevention of wrinkling in the same criterion. Steel sheet of SPCD grade with thickness of 0.2 mm is used to generate the cylindrical cupshaped product with 40 mm diameter. Analytical Results of minimum VBHF have a similar trend result compared to FE simulation. However, the minimum VBHF can be quite effective for preventing the occurrence of excessive wrinkle.

    Langs, R

    1976-01-01

    Using the data from Blank's (1976) description of his clinical efforts with his first patient, selected tissues on becoming a psychiatrist and psychotherapist are explored. Considered among the motives for entering this profession are opportunities for the therapist to projectively identify into his patients, and to introjectively identify with and contain his patients' psychopathology. The relationship between empathy and intuition on the one hand, and projection and projective identification on the other, is also studied, as is the need for the application of the validating process in confirming all so-called empathic and intuitive responses on the part of the therapist. Counter-transference influences on the experience and use of empathy and intuition are also investigated. The development of therapeutic misalliances and framework "cures," the distinction between transference and nontransference, the constructive elements contained in essentially countertransference-based interventions, the mastery of countertransference difficulties, and the choice of insight-oriented versus noninsightful therapeutic modalities are discussed.

    2013-10-01

    The absolute optical thickness of a 140-mm2 mask blank glass plate 3.1 mm thickness was measured by three-surface interferometry using a wavelength-tuning Fizeau interferometer. The interference order was determined by the excess fraction method. The wavelength of a tunable laser diode was scanned linearly from 632 to 642 nm, and a CCD detector recorded 2000 interference images. Two kinds of optical thicknesses measured by discrete Fourier analysis and phase-shifting were synthesized to obtain the optical thickness with respect to the ordinary refractive index. The optical thickness defined by the group refractive index at the 637 nm central wavelength was measured by wavelength scanning. The optical thickness deviation defined by the ordinary refractive index was measured using tunable phase-shifting. The systematic errors caused by nonlinearity in the wavelength tuning were corrected through correlation analysis between the theoretical and observed interference fringes.

    2005-01-01

    According to the characteristics of a complex cover panel, its geometry shape is described by the NURBS surface with great description capability. With the reference to the surface classification determined by Gauss curvature, the proportion of the mid-surface area between before and after being developed is derived from the displacement variation of the mid-surface in the normal vector direction of the sheet metal during the sheet metal forming process. Hereby, based on the curve development theory in differential geometry, a novel diagonal point by point surface development method is put forward to estimate a complex cover panel's blank contour efficiently. By comparing the sample's development result of diagonal point by point surface development method with that of available one-step method, the validity of the proposed surface development method is verified.

    It is expected that the next generation of large ground based astronomical telescopes will need large fast-steering/tip-tilt mirrors made of ultra-lightweight construction. These fast-steering mirrors are used to continuously correct for atmospheric disturbances and telescope vibrations. An example of this is the European Extremely Large Telescope (E-ELT) M5 lightweight mirror, which is part of the Tip-Tilt/Field-Stabilization Unit. The baseline design for the E-ELT M5 mirror, as presented in the E-ELT Construction Proposal, is a closed-back ULE mirror with a lightweight core using square core cells. Corning Incorporated (Corning) has a long history of manufacturing lightweight mirror blanks using ULE in a closed-back construction, going back to the 1960's, and includes the Hubble Space Telescope primary mirror, Subaru Telescope secondary and tertiary mirrors, the Magellan I and II tertiary mirrors, and Kepler Space Telescope primary mirror, among many others. A parametric study of 1-meter class lightweight mirror designs showed that Corning's capability to seal a continuous back sheet to a light-weighted core structure provides superior mirror rigidity, in a near-zero thermal expansion material, relative to other existing technologies in this design space. Corning has investigated the parametric performance of several design characteristics for a 3-meter class lightweight mirror blank for the E-ELT M5. Finite Element Analysis was performed on several design scenarios to obtain weight, areal density, and first Eigen frequency. This paper presents an overview of Corning ULE and lightweight mirror manufacturing capabilities, the parametric performance of design characteristics for 1-meter class and 3-meter class lightweight mirrors, as well as the manufacturing advantages and disadvantages of those characteristics.

    Full Text Available The research examined the connection between vocational education, training and the world of work, and the social situation in Hungary in a European outlook. The accentual issues of the analysis disclosing the problem are: youth unemployment, the tendencies of secondary vocational education, proportions of enrollment and the features of training tendencies, the growing number of early dropouts, the effect of family background on student performance. This work tried to find the answer to the question: What variations have the changes in the regulations of vocational training, encouraging dual education brought on in the connection between trainers and work places? The research did not prove that the central vocational training system would be more effective than a varied, flexible, permeable, transparent decentralized operation with parts built on each other. The introduction of the complex exam overshadowed the evaluation of the competency areas, and fits less to the modularity of the framework curricula. With the legal regulation of vocational training in force the modular system has become a formality. Taking prior knowledge into account has become more difficult. The efficiency of professional structural decisions is questionable, it has not triggered the extension of employment among career starters, and does not mean a guarantee of finding a job either. Creating the motivation of economic role players may bring on steps forward to take up bigger tasks in vocational training. The research has confirmed the importance of improving the basic competency areas when planning vocational training, of life-long learning, of practice orientation, and also of the continuous connection with the labor market.

    Over the past decade, there has been growth in the delivery of vocational rehabilitation services globally, as countries seek to control disability-related expenditure, yet there has been minimal research outside the United States on competencies required to work in this area. This study reports on research conducted in Australia to determine current job function and knowledge areas in terms of their importance and frequency of use in the provision of vocational rehabilitation. A survey comprising items from the Rehabilitation Skills Inventory-Amended and International Survey of Disability Management was completed by 149 rehabilitation counselors and items submitted to factor analysis. T-tests and analyses of variance were used to determine differences between scores of importance and frequency and differences in scores based on work setting and professional training. Six factors were identified as important and frequently used: (i) vocational counseling, (ii) professional practice, (iii) personal counseling, (iv) rehabilitation case management, (v) workplace disability case management, and (vi) workplace intervention and program management. Vocational counseling, professional practice and personal counseling were significantly more important and performed more frequently by respondents in vocational rehabilitation settings than those in compensation settings. These same three factors were rated significantly higher in importance and frequency by those with rehabilitation counselor training when compared with those with other training. In conclusion, although 'traditional' knowledge and skill areas such as vocational counseling, professional practice, and personal counseling were identified as central to vocational rehabilitation practice in Australian rehabilitation agencies, mean ratings suggest a growing emphasis on knowledge and skills associated with disability management practice.

    The Upgraded Coal Interest Group (UCIG) is an EPRI 'users group' that focuses on clean, low-cost options for coal-based power generation. The UCIG covers topics that involve (1) pre-combustion processes, (2) co-firing systems and fuels, and (3) reburn using coal-derived or biomass-derived fuels. The UCIG mission is to preserve and expand the economic use of coal for energy. By reducing the fuel costs and environmental impacts of coal-fired power generation, existing units become more cost effective and thus new units utilizing advanced combustion technologies are more likely to be coal-fired.

    The Field Contamination Study (FCS) was designed to determine the field processes that tend to result in clean field blanks and to identify potential sources of contamination to blanks collected in the field from selected volatile organic compounds (VOCs) and wastewater-indicator compounds (WICs). The VOCs and WICs analyzed in the FCS were detected in blanks collected by the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program during 1996-2008 and 2002-08, respectively. To minimize the number of variables, the study required ordering of supplies just before sampling, storage of supplies and equipment in clean areas, and use of adequate amounts of purge-and-trap volatile-grade methanol and volatile pesticide-grade blank water (VPBW) to clean sampling equipment and to collect field blanks. Blanks and groundwater samples were collected during 2008-09 at 16 sites, which were a mix of water-supply and monitoring wells, located in 9 States. Five different sample types were collected for the FCS at each site: (1) a source-solution blank collected at the USGS National Water Quality Laboratory (NWQL) using laboratory-purged VPBW, (2) source-solution blanks collected in the field using laboratory-purged VPBW, (3) source-solution blanks collected in the field using field-purged VPBW, (4) a field blank collected using field-purged VPBW, and (5) a groundwater sample collected from a well. The source-solution blank and field-blank analyses were used to identify, quantify, and document extrinsic contamination and to help determine the sources and causes of data-quality problems that can affect groundwater samples. Concentrations of compounds detected in FCS analyses were quantified and results were stored in the USGS National Water Information System database after meeting rigorous identification and quantification criteria. The study also utilized information provided by laboratory analysts about evidence indicating the presence of selected compounds

  11. Rangifer and human interests

    Directory of Open Access Journals (Sweden)

    David G. Anderson

    2000-03-01

    Full Text Available This article reviews biological and anthropological literatute on wild and tame Rangifer to demonstrate the powerful effect that this species has had on the imaginations of biologists, social scientists and local hunters. Through identifying a general 'human interest' in Rangifer, the author argues that there is great potential for these three communities to work together. To demonstrate this idea, the paper reviews several examples of successful and unsuccessful 'alliances' between local peoples and both natural and social scientists which have had a fundamental impact upon the history of these sciences. The paper examines recent theorerical models which suggest that human action is a major factor in the behaviour and ecology of the animals. The paper also analyses the ideas of many indigenous people for whom there is no categorical difference between semi-domesticated, semi-sedentary and migratory Rangifer through comparison with many 'anomalous' texts in English and Russian language wildlife biology. By reviewing the history of scholarly interest in Rangifer, the author argues that contemporary models of Rangifer behaviour and identity could be 'revitalised' and 'recalibrated' through the establishment of that dialogue between scientists and local peoples which so characterised the 19th century. Such a dialogue, it is argued, would help mediate many of the political conflicts now appearing in those districts where Rangifer migrate.
