CBS TABANLI İÇMESUYU BİLGİ SİSTEMİ: ÖRNEK BİR UYGULAMA
Get PDFÖzet
Günümüzde kullanım alanı gün geçtikçe artan Kent Bilgi Sisteminin bileşenlerinden birisi olan Altyapı Bilgi Sisteminin küçük ölçekli yerleşim birimlerinde kullanımının yaygınlaştırılması ve bu tür yerlerde uygulanabilirliğinin araştırılması amacıyla gerçekleştirilen bu çalışmada Isparta ili Atabey ilçesi çalışma alanı olarak seçilmiştir. Bu amaçla Atabey ilçesi altyapı şebeke sistemlerinden olan içmesuyu şebeke sistemine ait haritalar (Planlar, veriler) temin edilmiş ve bunlar ArcView 9.0 Coğrafi Bilgi Sistemi programı aracılığıyla sayısallaştırılmıştır. Temin edilen grafik olmayan (sözel) veriler ile sayısallaştırılan veriler ilişkilendirilerek çalışma alanına ait bir veri tabanı oluşturulmuştur. Oluşturulan bu veri tabanında çeşitli sorgulama ve analizler gerçekleştirilmiştir. Tüm bu işlemler sonucunda İçmesuyu Bilgi Sisteminin küçük ölçekli yerleşim birimlerinde başarıyla uygulanabileceği sonucuna varılmıştır.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Use of Waste Phonolite as Filler Material in Flexible Asphalt Pavements
Get PDFI
In the scope of the study, the use of waste phonolite (PW) obtained from phonolite wastewater formed during the processing of phonolite stone blocks as filler in hot-mix asphalt (HMA) was investigated. For this purpose, samples were produced with 4 %, 5 %, and 6 % PW mineral filler and 5 % limestone (LS) mineral filler. Phonolite supplied as waste was sieved through a sieve no 200 and made ready for use as a filler. HMA specimens were prepared with PW and LS at the rates of 3.5 %, 4 %, 4.5 %, 5 %, 5.5 %, and 6 % bitumen. For each filler ratio, a bituminous hot mix design was made by the Marshall method and optimum bitumen ratios (OBR) were determined. Bituminous hot mixture specimens were prepared based on OBR. Retained Marshall stability (RMS) test, indirect tensile strength (ITS), and moisture damage resistance tests and Marshall stability (MS) test after the freeze-thaw (F-T) cycle was applied to the prepared Marshall samples. The results obtained were evaluated according to the Turkish Highway Technical Specification (HTS). As a result, it was determined that the PW could be used as filler in HMA under low-intensity traffic
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
LABORATORY INVESTIGATION OF USABILITY OF SLATE WASTE POWDER AS FILLER IN HOT MIX ASPHALT CONCRETE
Get PDFThe main objective of this experimental research was to investigate the effect of slate waste powder (SWP) as filler material in hot mix asphalt concrete. In the study, the use of slate collected during the shaping process of slate blocks in bituminous hot mixtures as mineral filler was investigated. For this purpose, four different serial asphalt concrete samples were produced using limestone (LS) in different proportions (4%, 5%, 6%, and 7%) as mineral filler. In this context, specimens were produced and tested under Marshall Stability (MS) Test, and the optimum bitumen content (OBC) value for the aggregate samples to be used was determined. Choosing the series of asphalt having 5% filler which has given the highest stability SWP was changed with LS filler in the rate of 25%, 50%, 75%, and 100%. After that MS and Indirect Tensile Strength (ITS) tests, comparatively was conducted on the produced samples and the results were evaluated. As a result, it has come in view that SWP can be used as mineral filler in bituminous mixtures.

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
