A Comparison of Grading Models for Neighborhood Level of Family Housing Units
No full textMore recently Turkey has witnessed fast housing development and real estate sector growth because of the mortgage preparations. With this development, property location quality has been considered important for selecting and paying them. This study uses a data set of new single family housing units in Kocaeli University Campus Area. By using 4 location quality criteria, 27 single family housing units are graded at the neighborhood level. It is aimed to examine the applications of grading property at the neighborhood level based on property location quality by testing with three methods. Traditional method and fuzzy logic method were discussed in our antecedent studies. In this study, an easy used numerical calculation method; Neural Networks (NN), is introduced. Its grading performance is compared with the previous methods. NN method is found to be more accurate and realistic than traditional grading approach where its designing stage is more practical and faster than fuzzy logic approach.

Big data governance, social media usage in searching for information and its effects on t-shaped skills
No full textÇağdaş organizasyonlarda büyük veri ve veri yönetişiminin kullanımı, işletme değeri ve getirileri ile karakterize edilmiştir. Günümüzde yükselen yeni bir değer olarak karşımıza çıkması ve artan önemine rağmen, büyük veri ve yönetişimi hakkında çok az sayıda araştırma yapılmıştır. Söz konusu çalışmalar da büyük verinin çalışanların geliştirilmesine katkı sağlaması hususuna odaklanmamıştır. Bu çalışmada ise, büyük veri yönetişiminin çalışanın sosy al medya kullanımı (bilgi arama ve müşteri ilişkileri geliştirme gibi) ve T-yetenek üzerindeki etkisini inceleyen bir model ele alınmıştır. Anket verileri Antalya Türkiye’de çeşitli kurumlarda çalışan avukatlardan (n = 324) elde edilmiş ve veri analizi için varyansa dayalı yapısal eşitlik modelleme (PLS-SEM) tekniği uygulanmıştır. PLS-SEM sonuçları büyük veri ve veri yönetişiminin sosyal medya kullanımı ve çalışanların T-yeteneği üzerinde olumlu yönde etki ettiğini göstermektedir. Bu çalışma, büyük veri önetişiminin sosyal medya kullanımı ve çalışanların T-yeteneğini geliştirme üzerindeki rolü hakkında verdiği fikirlerle diğer çalışmadan ayrılmaktadır. Teori, yönetim ve teknoloji üzerindeki etkilerinin tartışıldığı çalışma, araştırma sınırlılıkları ve gelecekte yapılacak çalışmalar için tavsiyeleri de içermektedirThe use of big data and data governance in contemporary organizations has been characterized by business value and returns. Despite the importance of big data and its governance, little research has focused on its effectiveness in helping and developing employees. Based on these arguments, we examine a model scrutinizing the impact of big data governance on employees' social media usage (i.e., for informational search and client-relational building) and T-shaped skills. Survey data were obtained from lawyers working in various chambers in Antalya, Turkey (n=324), and a variancebased structural equation modeling (PLS-SEM) technique was applied for data analysis. Results from PLS-SEM show that big data and data governance exert a positive impact on social media usage and employees' T-shaped skills. This study offers a nuanced insight into the role of big data governance on social media usage (i.e., for informational search and client-relational building) and employees' T-shaped skills development. Implications for theory, management, and technology are discussed alongside the limitations and future research directions.No sponso
Building task-oriented machine translation systems
No full textLa principal meta de esta tesis es desarrollar sistemas de traduccion interactiva que presenten mayor
sinergia con sus usuarios potenciales. Por ello, el objetivo es hacer los sistemas estado del arte mas
ergonomicos, intuitivos y eficientes, con el fin de que el experto humano se sienta mas comodo al utilizarlos.
Con este fin se presentan diferentes t�ecnicas enfocadas a mejorar la adaptabilidad y el tiempo
de respuesta de los sistemas de traduccion automatica subyacentes, as�ÿ como tambien se presenta una
estrategia cuya finalidad es mejorar la interaccion hombre-m�aquina. Todo ello con el proposito ultimo
de rellenar el hueco existente entre el estado del arte en traduccion automatica y las herramientas que los
traductores humanos tienen a su disposici�on.
En lo que respecta al tiempo de respuesta de los sistemas de traducci�on autom�atica, en esta tesis se
presenta una t�ecnica de poda de los par�ametros de los modelos de traducci�on actuales, cuya intuici�on est�a
basada en el concepto de segmentaci�on biling¤ue, pero que termina por evolucionar hacia una estrategia de
re-estimaci�on de dichos par�ametros. Utilizando esta estrategia se obtienen resultados experimentales que
demuestran que es posible podar la tabla de segmentos hasta en un 97%, sin mermar por ello la calidad
de las traducciones obtenidas. Adem�as, estos resultados son coherentes en diferentes pares de lenguas,
lo cual evidencia que la t�ecnica que se presenta aqu�ÿ es efectiva en un entorno de traducci�on autom�atica
tradicional, y por lo tanto podr�ÿa ser utilizada directamente en un escenario de post-edici�on. Sin embargo,
los experimentos llevados a cabo en traducci�on interactiva son ligeramente menos convincentes, pues
implican la necesidad de llegar a un compromiso entre el tiempo de respuesta y la calidad de los sufijos
producidos.
Por otra parte, se presentan dos t�ecnicas de adaptaci�on, con el prop�osito de mejorar la adaptabilidad
de los sistemas de traducci�on autom�atica. La primeraSanchis Trilles, G. (2012). Building task-oriented machine translation systems [Tesis doctoral]. Universitat Politècnica de València. https://doi.org/10.4995/Thesis/10251/17174Palanci

Evaluation of the facial bone thickness of first and second maxillary molars: a cone-beam computed tomography study
No full textObjective: Facial alveolar bone (FAB) thickness has crucial clinical importance due to its effect on periodontal surgery, immediate implant placement. The purpose of the present study is to investigate facial alveolar bone thickness of maxillary first and second molars by cone-beam computed tomography (CBCT). Material and method: Sixty-eight CBCT images belong to non-smoking healthy patients were retrospectively scanned and 84 three-rooted maxillary molars were selected. Endodontic treatment, post-core restoration, furcation and periapical lesion, root resorption, periodontal loss and previous orthodontic treatment were excluded from the study. FAB thicknesses of mesial and distal roots were measured at bone crest, 6 mm from bone crest and apical level of the root. Images were viewed on coronal, axial and sagittal plane in CBCT. The statistical analysis was performed. Results: FAB thicknesses of mesial and distal roots of first molar were 0,58 and 0,75 mm at bone crest and 0,39 and 0,96 mm at 6 mm from bone crest and 1,06 and 1,18 mm at apical, respectively. For second molar, 0,80 and 1,15 mm at bone crest and 1,52 and 1,48 mm at 6 mm from bone crest and 2,81 and 2,09 mm at apical, respectively. There is a statistically significant difference between the mesial root of the first and second molar at the bone crest, 6 mm from the bone crest, and apical of the root. For the distal root, there is a significant difference between the first and second molar at the bone crest and 6 mm from the bone crest. There is no significant difference at the apical of the root. Conclusion: The present study concluded that FAB thickness of the distal root of the fist molar is lower than the second molar. It is recommended the detailed examination of FAB thickness of the first molar when implant or periodontal surgery is needed.Amaç: Fasiyal alveoler kemiği kalınlığı, periodontal cerrahi ve çekim sonrası immediate implant yerleştirilmesi ve soketin boyutsal değişiklikleri üzerindeki etkisi nedeniyle klinik öneme sahiptir. Bu çalışmanın amacı; birinci ve ikınci maksiller molar dişlerdeki fasiyal alveoler kemik kalınlığının konik ışınlı bilgisayarlı tomografi (KIBT) kullanarak incelenmesidir. Yöntem: Sigara içmeyen sağlıklı hastaya ait altmış sekiz KIBT görüntüsü retrospektif olarak tarandı ve 84 üç köklü maksiller molar diş (42 birinci ve 42 ikinci molar) seçildi. Endodontik tedavili, post-core uygulanmış, furkasyon ve periapikal lezyonlu, kök rezorpsiyonlu, periodontal kaybı olan ve ortodontik tedavili dişler çalışma dışı bırakıldı. Mezial ve distal köklerin fasiyal alveolar kemik kalınlıkları kret tepesinden, kret tepesinin 6 mm apikalinden ve kökün apikal seviyesinden ölçüldü. Görüntüler KIBT'de x5 büyütmede koronal, aksiyel ve sagital düzlemde incelendi. İstatistiksel analiz yapıldı. Bulgular: Birinci moların mezial ve distal köklerinin kemik kalınlıkları kret tepesinde 0,58 ve 0,75 mm, kret tepesinden 6 mm apikalde 0,39 ve 0,96 mm ve apikalde 1,06 and 1,18 mm olarak ölçüldü. İkinci molar için kret tepesinde 0,80 ve 1,15 mm, kret tepesinden 6 mm apikalde 1,52 ve 1,48 mm ve apikal seviyede 2,81 ve 2,09 mm olarak ölçüldü. Student t-testi, birinci ve ikinci molar dişlerin mesial köklerinin kemik kalınlıkları arasında kret tepesinde, kret tepesinin 6 mm apikalinde ve kökün apikalinde istatistiksel olarak anlamlı bir fark olduğunu gösterdi. Distal kök için, birinci ve ikinci molarların bukkal kemik kalınlıkları arasında kret tepesinde, kret tepesinin 6 mm apikalinde istatistiksel olarak anlamlı bir fark vardır. Kökün apikal seviyesinde fark yoktur. Sonuç: Bu çalışma, birinci moların mezial kökünün alveoler kemik kalınlığı ikinci molardan daha düşük olduğunu göstermiştir. Aynı şekilde, birinci molarların distal kökün alveolar kemik kalınlığı, kret tepesi ve kret tepesinin 6 mm apikalinde ikinci molardan daha düşüktür. Birinci molarlara implant cerrahisi ve periodontal cerrahi gerekliliğinde bu bölgedeki kemik kalınlığının daha ayrıntılı incelenmesi önerilmektedir.No sponso
Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
Analysis of some flexible families of distributions for estimation of wind speed distributions
No full textWOS: 000296114700042The wind speed distribution is the basis for the assessment of wind energy potential needed for the design of wind farms. Therefore, the proper specification of the wind speed distribution is of special importance. In this study, we propose for the first time two flexible families of distributions, the skewed generalized error and skewed t, for the description of the wind speed distribution. These families both are very flexible enough to accommodate the shape of the wind speed data and include some well-known distributions as special cases. Also we evaluate the performance of these flexible families relative to the widely-used Weibull distribution by using wind speed data measured in various regions of Turkey. The results indicate that these flexible families of distributions provide substantial improvement over the Weibull distribution in estimating wind speed distribution and wind power density distribution. Thus, the skewed generalized error and skewed t distributions can be alternatively used for assessment of wind energy potentia
