پایگاه داده تحلیلی جهت نگهداری داده ها با ساختاری مناسب برای تحلیل بکار می رود. فرآیند استخراج، تبدیل و بارگذاری عبارت است از تبدیل بعضی از داده های منبع به فرم مناسب، و انتقال آن ها به پایگاه داده تحلیلی که شامل سه مرحله کلی استخراج، تبدیل و بارگذاری داده است. در طی این مراحل، داده ها از یک یا چند پایگاه داده منبع به یک پایگاه داده تحلیلی منتقل می شوند. معمولا ساختار منبع داده (مدل رابطه ای و....

The electron transport layer (ETL) in an organic solar cell is one of the main components that play a crucial role extraction charges, improving efficiency, and increasing lifetime cells. Herein, solution-processed PBDTTT-C-T:PC71BM-based cells are fabricated using conjugated PDINO molecules, sol-gel derived under stoichiometric titanium oxide (TiOx), mixture same as ETL. For cells, blend organ...

In order to realize both efficient and stable perovskite solar cells, designing electron transport layer (ETL) is of crucial importance withstand constant light illumination thermal stress while maintaining high charge extractability. Herein, commonly used SnO2 nanoparticle-based ETL for cells modified by ionic-salt ammonium chloride (NH4Cl) tin dihydrate (SnCl2∙2H2O) as additives, which easily...

HEIS (Higher Education Information System) is a project funded by the Croatian Ministry of Science, Education and Sports started in the year 2001. HEIS is a comprehensive information system that provides support for education related processes taking place within a higher education institution. As a part of the project, a data warehouse was developed to provide reporting and analytical features...

XBRL is a standard language for publicating finantial reports over the Web that is based on XML and XLink. Currently, there are no computational tools to integrate XBRL data with information stored in other formats. ETL tools responsible for data materialization integration do not provide a means of navigating in XLink­based documents such as XBRL documents. Thus, in this paper, a framework arc...

The efficiency and stability of perovskite solar cells (PSCs) depend not only on the film quality, but they are also influenced by charge carriers both electron hole transport layers (ETL HTL). Doping carrier is considered one effective technique applied to enhance performance PSCs. FK209 cobalt TFSI lithium salt were investigated as dopants for mesoporous TiO2 (M-TiO2) in ETL. Herein, doping o...

ETL processes play an increasingly important role for the support of modern business operations. These business processes are centred around artifacts with high variability and diverse lifecycles, which correspond to key business entities. The apparent complexity of these activities has been examined through the prism of Business Process Management, mainly focusing on functional requirements an...
