Maneuvering of slender X-fin AUVs with hydrodynamic derivatives informed through CFD
… with the generation of Lumped Parameter Models (LPM) for two, slender, torpedo shaped, X-fin craft. This process involves the use of CFD to simulate captive maneuvers that are normally performed using test equipment in the field. These captive maneuvers are refereed to as planar motion mechanisms …

Ultra-fine soot investigation in flames
… was performed for SMPS inlet flowrates of 1 lpm and 2 lpm while keeping a constant ratio of inlet to sheath air flowrate of 1 : 10. The 2 lpm flowrate results gave much smaller particle diameters compared to the 1 lpm flowrate results. The shift in particle diameters was around 6 nm. This …

Fostering Self-Authorship in the Student Conduct Environment
The Learning Partnerships Model (LPM) (Baxter Magolda and King, 2004) is a framework for promoting self-authorship. Self-authorship is a holistic development theory that employs three dimensions (epistemological, intrapersonal, interpersonal). The LPM can be tailored to a variety of academic tasks, …

RST invariant digital image watermarking
… We embed watermark in the log-polar mapping (LPM) of the Fourier magnitude spectrum of original image, and use the phase correlation between the LPM of the original image and the LPM of the watermarked image to calculate the displacement of the watermark positions in LPM domain. The exhaustive …

Factors Influencing the Nitrification Efficiency of Fluidized Bed Filters With a Plastic Bead Medium
… four different flow rates, ranging from 6 Lpm–12 Lpm, were tested at constant ammonia feed level (8.4 g/day). Here, biofilter D3 (17.8 cm diameter) showed the best ammonia removal performance at a flow rate of 6 Lpm, followed by the performance of D1 (12.7 Lpm) and D2 (15.2 Lpm). The …

Comparison of concentrations in the breathing zone
… lapel. Nose was sampled at l liter per minute (lpm) and 0.15 lpm at different times, while the others were sampled at 0.15 lpm at two different wind tunnel velocities. The source was released at naval height for each subject.;It was concluded that wind tunnel velocities, and ratios of the chest …

Investigating the Reconstitution and Function of Peritoneal Cavity Macrophages after LPS-induced Peritonitis
… the GATA6+ large peritoneal macrophages (LPMs) are responsible for the clearance and removal of pathogens that may break through the defensive barriers of the abdomen. However, upon inflammation incurred by the response of the immune system to foreign matter, the LPM population seemingly …

A Design Space Exploration Process for Large Scale, Multi-Objective Computer Simulations
… metamodeling scheme, the lumped parameter model (LPM), was developed to address two primary limitations to the current partitioning methods for large scale metamodeling. First the LPM was formulated to negate the need to rely on variable redundancies between partitions to account for potentially …

Investigation into the use of a tapered element oscillating microbalance for real-time particulate measurement
… was varied from one to four liters per minute (lpm). The 1 lpm set point provided the best TEOM to conventional filtration ratio. The flow rate of 3 lpm was chosen to be a compromise between TEOM to conventional filtration ratio and real-time results. The best TEOM to conventional filtration …

Thermal particle production in the early universe
… known under the name "Landau-Pomeranchuk-Migdal (LPM) effect" and has so far only been considered for the computation of photon production rates from a quark-gluon plasma. In this thesis, a conceptually new approach to take gauge interactions consistently into account at leading order is …

Optimization of a magnetically saturable interior permanent-magnet synchronous machine drive
… A magnetically-saturable lumped parameter model (LPM) is developed for the optimized design of high-performance IPM synchronous machine drives. Using equivalent magnetic circuit analyses, the dq-frame inductances and magnet flux linkage are calculated for transversely-laminated IPM machines. The …

Transient CaMK-II Activation is Necessary for Left-Right Asymmetry in the Zebrafish Embryo
… (spaw) expression in the Lateral Plate Mesoderm (LPM). Interestingly, activated CaMK-II (P-CaMK-II) appears transiently in cells on the left side of the KV following Ca2+ elevation, and prior to spaw expression in the LPM. These findings indicate a role for CaMK-II in the processing or secretion …

Providing Safe Gastric Feedings In Pediatric Patients On High Flow Nasal Cannula Respiratory Support
… rates, with a median of 10 liters per minute (LPM) (IQR 10-12) compared to a median of 8 LPM (IQR 6-10), p = 0.007. Even with gastric feeding initiation at higher flow rates post-intervention, there were no AEs, no statistical differences in vital signs before or after feeds, and no reduction …

Causes and analysis of failures in in-situ microscopy observation for the characterization of scaling in membrane distillation membranes
… pumped across a membrane at 70°C at 2.6 GPM (9.8 LPM) to observe membrane fouling. Using an in-situ camera, fouling on a membrane distillation surface was captured to characterize the nature of MD fouling.
