High quality suppliers are necessary for the success of any organization. To guarantee good quality products from suppliers, it is necessary to optimize the process parameters immediately when deviations of the part quality, that is required by the customer, have been observed. Optimization of process parameters are only possible when an experienced process operator adjusts the parameters of the process manually. Although statistical process control (SPC) enable the quality of conformance to be monitored and special causes of process variability to be identified, it is not well applied in some enterprises due to fact that operators . . .cannot determine the 'out-of-control' position of the process, and the root causes of the quality problems with the limited knowledge they have. Therefore, the presented approach develops a system which combines dynamic control chart with the expert knowledge library. The system is carried out in two steps: the first step, a quality controller checks the product quality according to the reference values, when the process is going to be out of control, the system will give a warning to remind operators to take action exactly and keep the process in normal; in the second step, the system will give the related information and valuable suggestions to operator and help them to take correct action to keep the process in control.

Effect of Polypropylene Fibers on Freeze-Thaw Resistance, Surface Scaling and Flexural Toughness of Concrete

Soylev, TA | Ozturan, T

Conference Object | 2012 | 7TH ASIAN SYMPOSIUM ON POLYMERS IN CONCRETE , pp.737 - 744

Fibers do not provide significant increase in the strength of concrete at low fiber volumes commonly used in practice. The main benefits of fibers result from the control of the width of cracks in concrete. Polypropylene fiber is one of the most popular polymer fibers used in concrete, which has been shown to be effective in controlling the plastic shrinkage at the content of approximately 0.1% by volume. However, as polypropylene fibers are low modulus fibers and used at such low contents, it is difficult to expect an improvement in the crack control of hardened concrete in theory. In the present study, the effect of a multi-filame . . .nt polypropylene fiber on the resistance of concrete to surface scaling and freeze-thaw attack is investigated. Polypropylene fiber reinforced concrete was also tested under flexural load. Two different water/cement ratios were used for concrete production. The results indicated that polypropylene fibers can be beneficial in the control of micro-cracking induced by freeze-thaw cycling and surface scaling. The development of cracks under flexural load was not affected significantly by the presence of the polypropylene fibers Daha fazlası Daha az

A phenomenological study of spatial experiences without sight and critique of visual dominance in architecture

Basvazici-Kulac, B | Ito-Alpturer, M


Architectural phenomenology suggests that the basis of perceptual integrity between the subject and a space is multi-sensorial. However, the advancement of visual representation techniques within architecture has led to predominance of the visual experience over other sensory modalities. As a consequence, the integrity of the user's multi-sensorial appreciation of space has been largely neglected which may impact on the holistic experience of the individual. The present study uses an architectural phenomenology approach to explore user experiences of architectural spaces without reference to visual input: the aim being to elucidate . . .key sensory modalities that drive a synthesis of the spatial experience in the absence of visual cues. In this way, the study aims to highlight the role of the non-visual, as a criticism against the tendency to present architecture as a predominantly visual phenomenon. A qualitative study of spatial experiences from four congenitally blind and three late blind individuals was carried out within the framework of architectural phenomenology. Thus, although all suffered total loss of sight, it was possible to assess the impact of latent visual memories within the second group. In-depth interviews with each participant explored responses to four semi-structured, open-ended questions. They were asked to describe; 1) what an architectural space means to them, 2) the place they live, 3) the most important architectural features that affect their experience either positively or negatively and 4) the most favourable and unfavourable place they had ever been. No time limit was imposed for answering the questions. The answers were audio recorded with permission. All participants judged an architectural space predominantly by its acoustic properties, with no clear difference between the congenital or late blindness subgroups. A frequently mentioned construct was the sense of spaciousness with the acoustic properties of architectural features such as materials and ceiling height identified as critical determinants. Tactile experiences, in the form of air circulation felt on the skin also helped the participants to judge spaciousness. But, it was odour that was often described as the feature that defines the identity of a place. Contrary to common beliefs, tactile experiences using the hands were mentioned least. We conclude that non-visual senses subserve a central role in the formulation of spatial experiences for the visually impaired and postulate that they may have similarly significant impact on the experiences of the visually adept. Designing the properties of different acoustical ambiances to promote a synergy of sensory experiences through, for example, the selection of materials or dimensional adjustment at intersections, voids, openings and atria rather than concentrating on visual impact alone would enrich the environmental experience significantly Daha fazlası Daha az

The main goal of this thesis is to investigate the effect of two vocabulary learning approaches: 1) Computer-assisted Language Learning (CALL) with a computer-based flashcards program, Quizlet, 2) Keeping vocabulary notebooks on high school EFL learners' vocabulary learning. The vocabulary targeted for the study is determined from three sequential units of the textbook. The units are determined randomly considering the starting date of the study. Eighty-nine students in four beginner EFL classes were randomly assigned as control or treatment groups. A computer-based flashcard program (Quizlet) and a vocabulary notebook program was i . . .mplemented in two different classes over a 3 week period. The remaining two classes acting as control groups followed the same curriculum with the same materials without using Quizlet or keeping vocabulary notebooks. Vocabulary acquisition was measured by pre, post and delayed post-tests of unannounced vocabulary tests including orthography, grammatical accuracy and use adapted from [1] Laufer & Goldstein (2004) and, meaning and form, adapted from [2] Webb (2009). Pre, post and delayed post-test scores of students were analyzed to evaluate the effectiveness of the learning process. Learners' perceptions about the training are also investigated by means of interviews. The results show that participants who learned the target words through Quizlet Flashcard Software Program outperformed those who completed the tasks by means of vocabulary notebook and control group. The analysis of the differences between the two tasks (receptive and productive) for each aspect (orthography, meaning and form, grammar) shows that the tasks measuring receptive knowledge led to significantly higher gains than tasks measuring productive knowledge of all three groups Daha fazlası Daha az

The effectiveness of instructional design for developing listening comprehension in English as a second language (L2) is of prime concern to language teachers. Several technology based instructional designs with the emphasis on distinct presentation of listening tasks are highlighted in literature. However, there are a lack of empirical studies to clarify issues concerning modality differences for foreign language (FL) learners and their effect on comprehension. Moreover, learners' listening performance may be affected by the modality in which the tasks are presented (extraneous cognitive load) or the amount of cognitive resources t . . .hat learners invest in schema construction and automation (germane cognitive load). Based on cognitive load theory, this study examines whether the subjects' listening performance varied when the instructional formats of listening tasks were presented in three different modalities. Listening with auditory materials only (LO), narrow listening (NL), listening with a full written script (LFS) were employed to evaluate the subjects' listening performance. This study employs a mixed method design utilizing qualitative and quantitative tools including semi-structured interviews with test takers to assess the best facilitating modality for listening comprehension as well as post test scores to determine student performance. Two hundred and eight, intermediate and advanced level pre-service teacher candidates of English whose L1 was Turkish completed four tests through different representations that required them to listen to dialogues and to complete a number of multiple choice comprehension questions Daha fazlası Daha az

Pharmacogenetics has its roots in the 1950s with pioneering studies of monogenic variations in drug metabolism and pharmacokinetics. With the availability of high-throughput genomics technologies and the completion of the Human Genome Project in 2003, we are now in the postgenomics era. This transition is increasingly marked with study of polygenic and multifactorial traits such as common complex human diseases as well as pharmacodynamic differences among populations. Changes that emerge from postgenomics medicine are not, however, limited to seismic shifts in scale and scope of pharmacogenetics research. Importantly, many low- and . . .middle-income countries (LMICs) of the South, Asia-Pacific, Eastern Mediterranean and the Middle-East are becoming notable contributors with rapid globalization of science and increasing access to genomics technologies. This brings about, in parallel, an acute demand for regional capacity building in LMICs so that the future evaluation and implementation of postgenomics technologies in personalized medicine take place in an integrated, sustainable and equitable manner. With this overarching vision, we herein report the founding of the Istanbul Working Group in Personalized Medicine (IWG-PM, represented by the authors of this report) that was inaugurated as a component of the 2nd Symposium on Personalized and Predictive Medicine held in Istanbul, sponsored by the Yeditepe University, and the Turkish Scientific and Technological Research Council (TUB?TAK) (10-12 September, 2009). While highlighting the applications of personalized medicine in oncology, psychiatry, nutrition, infectious diseases, occupational health, genetic testing and systems biology, the symposium also raised challenging questions in the context of LMICs. How can we best evaluate the promises, intended and unintended impacts of personalized medicine and enabling technologies in the context of Turkey, and the LMICs more generally? IWG-PM is a small but significant and necessary step to initiate regional capacity building in Turkey. We trust that the IWG-PM initiative may also provide a constructive example to further develop capacity in other LMICs in the Eastern Mediterranean region. © 2009 Bentham Science Publishers Ltd Daha fazlası Daha az

Role of Studio Exercises in Digital Design Education Case Study of the Nine-Square Grid

Yazar, T | Pakdil, O

Conference Object | 2009 | ECAADE 2009: COMPUTATION: THE NEW REALM OF ARCHITECTURAL DESIGN , pp.145 - 151

This paper is about short term and contextually limited kit-of-parts exercises in architectural education. Studio exercises are one of the key educational tools in architecture, which should be reconsidered with the developing technologies. As design computing becomes the mainstream thinking in architecture, the need for not only renewed studio exercises but for new educational frameworks becomes an essential issue. Thus, in this paper we will be proposing a different perspective on digital studio education, by explaining the fundamentals of studio exercises and their digital transformation potentials. Our experience with one of the . . . most common kit-of-parts exercises, the nine-square grid, as a computational design problem for the first year students will be presented here as a part of this on going study Daha fazlası Daha az

This paper is going to be centred on how learners' autonomy can be fostered. In the literature part of this paper it is stated that the development autonomous learning plays a crucial role in learning process. Autonomy is about how people control their own lives, so when teaching/learning process is taken for granted, teachers create an environment that the students feel themselves autonomous. So autonomy is analyzed both from the teachers' and students' perspective. It analyzes whether the students are independent or not throughout the learning process. The scope of the research is to analyze the teachers' perspectives towards lear . . .ner autonomy during the class activities. For that purpose the literature part of that research paper is based on teachers' perspective towards their learners' autonomy. The empirical research is conducted on one of main private university in Istanbul. Convenient quota sampling has been used. 37 English Language Teachers covering a wide-range of departments participated in the research. The questionnaire is in Likert Scale form from strongly agree to strongly disagree and a space is provided on the questionnaire in order to analyze participants' opinions. Additionally correlation analyses and mean results are found, the results of the questionnaires are correlated with the findings of the literature review. The participants are given a questionnaire that analyzes how teachers assess their learners in terms of they are autonomous or not. The findings reveal that teachers have a significant effect on autonomous learning is general Daha fazlası Daha az
