Air-ice-ocean interactions under a summer Arctic cyclone: observations from two ice-tethered profilers
An Arctic cyclone passed over two Ice-Tethered Profilers (ITPs) in the Western Arctic Ocean on 28 July 2020. Each ITP measured ocean conditions from 7 to 750m depth, collecting data immediately before and after the storm that is used to quantify changes in ocean conditions. Prestorm conditions were …

Road Profiler Performance Evaluation and Accuracy Criteria Analysis
… and evaluated the performance of available profilers and several profiler accuracy criteria have been proposed. However, there is not a definite answer on the ability of available profilers to accurately measure the actual road profile as well as the various smoothness indices. A recent …

Investigation of in Silico Modelling to Predict the Human Health Effects of Cosmetics Ingredients
… this thesis was to assess the current in silico profilers for carcinogenicity (both genotoxic and non-genotoxic), mutagenicity and skin sensitisation through assessment using multiple high-quality experimental databases. The research presented herein demonstrates the ability to assess the …

EProf : an energy profiler for the iPAQ
… profiles the energy use of a Compaq iPAQ. Energy profilers help determine what parts of code are most energy-intensive so that programmers can concentrate on software hotspots. EProf uses statistical sampling to measure an iPAQ's energy use under a variety of working conditions. The EProf …

The Development of a Fragment-Based in silico Profiler for the Prediction of Thiol Reactivity and Toxicity
… the key shortcoming of traditional in silico profilers, this being that current in silico profilers provided no information about the rate of covalent bond formation for chemicals containing the same structural alert but with different substituents. The research within this thesis addresses …

Intelligent Planning and Assimilation of AUV-Obtained Measurements Within a ROMS-Based Ocean Modeling System
… that traditional measurement systems (bouys, profilers, etc.) cannot. A ROMS-based data assimilation method was developed that intelligently plans for and integrates AUV measurements with the goal of minimizing model standard deviation. An algorithm developed for this system is first described …

Cilkprof : a scalability profiler for Cilk programs
… large log files that are typical of trace-based profilers. In addition, the profiling algorithm only incurs constant amortized overhead per measurement. CilkProf slows down the serial program execution by a factor of about 10 in the common case, on a well-coarsened parallel program. The slowdown …

Raindrop Size Distribution Retrieval And Evaluation Using An S-band Radar Profiler
Vertical pointing Doppler radar profilers are used to explore the vertical structure of precipitation cloud systems and to provide validation information for use in weather research. In this thesis, a theoretical radar rain-backscatter model was developed to simulate profiler Doppler spectra as a …

Locating cache performance bottlenecks using data profiling
… existing execution profiling tools. Typical profilers attribute costs to specific code locations. The costs due to frequent cache misses on a given piece of data, however, may be spread over instructions throughout the application. The resulting individually small costs at a large number of …

Marine Snow Settling Velocities at an Oil Spill Site and a Control Site in the Northern Gulf of Mexico
… snow cameras, and acoustic Doppler current profilers (ADCPs) were deployed at two sites below the continental shelf break. One site was underneath the oiling footprint near the location of the Deepwater Horizon wellhead and another site was away from the oiling footprint in an area of …

Development of a smartphone application to measure pavement roughness and to identify surface irregularities
… (IRI), which is often measured using inertial profilers. Inertial profilers are equipped with sensitive accelerometers, a height measuring laser, a distance measuring instrument, etc., to measure pavement profile. Modern smartphones are equipped with a number of sensors including a three-axis …

Exploring the effectiveness of loop perforation for quality of service profiling
… in such computations. In contrast to standard profilers, which simply identify time-consuming parts of the computation, a quality of service profiler is designed to identify subcomputations that can be replaced with new, potentially less accurate, subcomputations that deliver significantly …

Scattering of the low-mode internal tide at the Line Islands Ridge
… data from three moorings equipped with moored profilers, spanning total depths of 3000-5000 m is analyzed to determine the modal content of the southward propagating internal tide before and after it encounters the ridge for evidence of topographic scattering.

High Resolution Measurements of the Mean Three-dimensional Flow Field in a Natural River
… discharge, boat-mounted acoustic Doppler current profilers (ADCP) are increasingly used in field studies to quantify flow features including mean velocity, boundary shear stress, and sediment motion. Two survey procedures are typically employed with an ADCP. Moving-vessel (MV) measurements provide …

Diel vertical migration and frontal variability of acoustic backscatter in the Balearic Sea
Acoustic Doppler current profilers (ADCPs) use active sonar to measure current velocities by measuring the sound returned by scatterers (most often zooplankton) in the water column. The volume of scatterers, or echo intensity, has been used to measure the abundance of zooplankton and characterize …
