Yüksek verimli perovskit güneş hücresi elde etmek için pin hole içermeyen, ince, yüksek şeffaflı, mükemmel taşıyıcı ayırma kabiliyetine sahip, üretimi kolay elektron transfer tabakasına (ETL) olması gereklidir. ETL malzemesi olarak hem kompakt (c-TiO2) de mezo (mp-TiO2) yapılı kullanılabilen TiO2’dir. Bu çalışmada üretilen ETL, c-TiO2’in sol-jel yöntemiyle hazırlanmış 2000, 2500, 3000, 3500 ve ...

A data warehouse architecture (DWA) has been developed for the purpose of integrating data from multiple heterogeneous, distributed, and autonomous external data sources (EDSs) as well as for providing means for advanced analysis of integrated data. The major components of this architecture include: an external data source (EDS) layer, and extraction-transformation-loading (ETL) layer, a data w...

Background and aims: Data from National Health and Nutrition Examination Survey for 2007-2010 were used to evaluate factors that affect observed variability in urinary phytoestrogens. Methods: Data for six phytoestrogen variables, namely, daidzein (DAZ), o-desmethylangolensin (DMA), equol (EQU), enterodiol (ETD), enterolactone (ETL), and genistein (GNS) were available for analyses. Regression m...

Data from the electronic medical record comprise numerous structured but uncoded elements, which are not linked to standard terminologies. Reuse of such data for secondary research purposes has gained in importance recently. However, the identification of relevant data elements and the creation of database jobs for extraction, transformation and loading (ETL) are challenging: With current metho...

Abstract Investigations into novel device architectures and interfaces that enhance charge transport collection are necessary to increase the power conversion efficiency (PCE) of antimony selenide (Sb 2 Se 3 ) solar cells, which have shown great promise as a low-cost high-efficiency alternative conventional silicon-based cells. The current work uses simulations design p-i-n n-i-p Sb -based cell...

Integration of spatial data into multidimensional models leads to the concept of Spatial OLAP (SOLAP). Usually, SOLAP models exploit discrete spatial data. Few works integrate continuous field data into dimensions and measures. In this paper, we provide a multidimensional model that supports measures and dimension as continuous field data, independently of their implementation.

The main subject of spatial joins is polygons and polylines. The processing of spatial joins can be greatly improved by the use of filters that reduce the need for examining the exact geometry of spatial objects in order to find the intersecting ones. Approximations of candidate pairs of spatial objects are examined using such filters. As a result, three possible sets of answers are identified:...
