Ionospheric scintillation frequently occurs in equatorial, auroral and polar regions, posing a threat to the performance of global navigation satellite system (GNSS). Thus, detection ionospheric is great significance regard improving GNSS performance, especially when severe occurs. Normal algorithms exhibit insensitivity strong that natural phenomenon appears only occasionally, such samples acc...

Chemical Vapor Deposition (CVD) is one of the most popular methods for producing Carbon Nanotubes (CNTs). The growth rate of CNTs based on CVD technique is investigated by using a numerical model based on finite volume method. Inlet gas mixture, including xylene as carbon source and mixture of argon and hydrogen as carrier gas enters into a horizontal CVD reactor at atmospheric pressure. In thi...

The advanced design of an analog mixed-signal circuit is not simple enough to meet the requirements performance matrix as well robust operations under process-voltage-temperature (PVT) changes. Even commercial products demand stringent specifications while maintaining system’s performance. main objectives this study are increase efficiency optimization process by configuring in multiple regress...

Objectives: To perform aspect extraction for opinion mining of learner comments in the online teaching-learning scenario. Methods : A machine learning model is developed extraction. The authors collected dataset consisting around 5000 from Coursera and performed analysis on dataset. validate results, standard SemEval2014 used. Findings: For both contextualised non word embeddings, compiled resu...

The aim of this research is to design a model for excellence in human resources emphasizing its results in organizational behavior. This research depending on the purpose of basic research is also based on the research project and the terms of data collection, research is a descriptive (non-experimental), exploratory and adaptive. The instrument used in this study is a questionnaire consisting ...
