Open-label study of absorption and clearance of 1% voriconazole eye drops
( American Society for Microbiology , 2016 , Article)Twenty participants undergoing elective cataract surgery received 1% voriconazole eye drops (1 drop per eye) either 20, 40, 60, or 80 min before surgery. Median voriconazole concentrations of 1.9 to 3.2 mg/liter in aqueous ... -
An open-loop technique for angle determination from position encoders
( IEEE , 2008 , Conference Paper)The paper presents a novel technique for the determination of the angle from low-frequency quadrature cosinusoidal signals produced, for example, by position sensors. In the presented scheme applied to a resolver, the ... -
Operation failure of risk analysis on floating storage and offloading
( IOP Publishing , 2023 , Conference Paper)The need for petroleum in daily life is increasing. The oil comes from the seabed, so it is necessary to have adequate facilities during the exploration and exploitation of crude oil. The process of distributing crude oil ... -
Operation of three-phase modular multilevel converter (MMC) with reduced number of arms
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)Conventional three-phase MMC consists of six-arms, each arm is controlled to generate unipolar voltage ranging from zero to Vdc where Vdc is the input DC voltage. Each arm voltage has two components (DC and AC components). ... -
Operational modeling of multistream heat exchangers with phase changes
( Wiley Subscription Services, Inc., A Wiley Company , 2009 , Article)Multistream heat exchangers (MSHE) enable the simultaneous exchange of heat among multiple streams, and are preferred in cryogenic processes such as air separation and LNG. Most MSHEs are complex; proprietary and involve ... -
Operational neural networks
( Springer , 2020 , Article)Feed-forward, fully connected artificial neural networks or the so-called multi-layer perceptrons are well-known universal approximators. However, their learning performance varies significantly depending on the function ... -
Operations strategies alignment patterns and service quality: Airline global analysis
( American Society for Quality , 2019 , Article)This article aims to analyze airline operations strategies to identify possible alignment patterns and their effect on airline service quality worldwide. An intensive analysis of more than 350 airlines operations strategies ... -
Opinions and experiences on the provision of care to people with mental illnesses: a qualitative study with Doctor of Pharmacy graduates after a rotation in psychiatry.
( Springer Nature , 2023 , Article)Pharmacists are vital to optimizing therapy of people with mental illnesses. Limited knowledge, lack of confidence, and mental health-related stigma can lead to pharmacists' reluctance in the provision of pharmaceutical ... -
Opportunistic routing and data dissemination protocol for energy harvesting wireless sensor networks
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)Recent advances in environmental sources harvesting technologies is a promising solution to provide sustainable energy sources for wireless sensor networks (WSN). Renewable energy sources such as solar, thermal and ... -
