Frequency and voltage partitioning in presence of renewable energy resources for power system (example: North Chile power network)
( IEEE Computer Society , 2016 , Conference Paper)This paper investigates techniques for frequency and voltage partitioning of power network based on the graph-theory. These methods divide the power system into distinguished regions to avoid the spread of disturbances and ... -
Frequency conversion layers for Si solar cell efficiency improvement
( Springer Nature , 2017 , Book chapter)SiNx and SiNx: Tb3+ thin layers deposited by reactive magnetron co-sputtering have been studied with the aim of optimizing the light management in Si solar cells. Those Si-based layers are developed to be compatible with ... -
Frequency of adjustment with comorbidity and illness severity scores and indices in cardiac arrest research
( Elsevier , 2017 , Article)Background Previous research demonstrates that results from observational research correlate well with results from clinical trials, and if the former are well designed these can guide clinical practice. Observational ... -
Frequency of Clinically Important RH and Kell Blood Group Antigens Among Blood Donors in Qatar
( HBKU Press , 2016 , Conference Paper)Background Very limited information is available about the prevalence of blood groups among Qatari population and residents. The information about frequencies of different blood group antigens is important to manage, ... -
