High Resolution Continuous Active Sonar
… work presented focuses on methods for achieving high range, Doppler, and angular resolution, while maintaining a high signal-to-interference plus noise ratio (SINR).</p><p>CAS systems transmit at or near 100\% duty cycle for improved update rates compared to pulsed systems. For this reason, CAS …

High-Resolution CMB Bispectrum Estimator
… a novel CMB bispectrum estimator suited for the resolution and sensitivity of future surveys. We discuss our high-resolution bispectrum estimator in the second section. Our code, named CMB-BEst, utilises a set of general basis functions to accurately constrain a wide variety of models. …

High resolution optical DNA mapping
… methods. We have developed Multi-color Super-resolution technique, with potential for high throughput and low cost, which can allow us to recognize more of these variations. Our technique has made 10–fold improvement in the resolution of optical DNA mapping. Using a 180 kb BAC clone as a model …

High-resolution spectroscopy of propargyl radical
The high resolution infrared spectrum of the $\nu\sb1$ acetylenic CH stretch of the propargyl radical H$\sb2$CC$\equiv$CH has been obtained by the color center laser kinetic spectroscopy method. The propargyl radical is produced by flash photolyzing stable precursors propargyl bromide or propargyl …

High-resolution studies of protoplanetary disks
… HD 72106 and HD 113766. Both objects are host to highly processed silicates, resembling those found in solar-system comets. We further present the first observational confirmation for an extended circumstellar dust disk around epsilon Eri obtained with the bolometer array SIMBA at the 15m radio …

High-Resolution Thermal Measurements in Fluids
Based on the thermal measuring methods for mass-flow sensors a thin-film sensor is presented allowing flow-rate measurements of down to 1 milligramm per hour, as required for application in medical dosing systems. <br>Due to the fast response of the sensor to thermal actuation and its low power …

High-resolution ultrasonic non-destructive testing
… and experimentally. It is demonstrated that the resolution of pulse-echo NDT is affected by diffraction effects which also complicate the interpretation of echo signals. These diffraction effects are interpreted in terms of the plane- and edge-wave model of *transducer fields. Improverents can be …

High-Resolution Nuclear Magnetic Resonance Microspectroscopy
… samples. Microcoils have been designed for higher magnetic fields (500 MHz) and also now incorporate a lock channel for longer two-dimensional (2D) experiments. Reference deconvolution and wavelet noise reduction have been used to address lineshape distortion and low signal-to-noise found in …

Quantitative high resolution transmission electron microscopy
High resolution transmission electron microscopy (HRTEM) has been extensively used as a structure characterization technique in materials and biological science. In the past, qualitative use of HRTEM has been primarily employed.

An ultra high resolution FMCW radar
… requirement for these type of applications is high resolution. This is a standard problem in radar. Using classical signal processing techniques, the range resolution is proportional to the bandwidth of the transmitted signal. This poses a serious problem in radar as very large bandwidths are …

High resolution simulation of a vacuum microdiode
In this thesis a vacuum microdiode is simulated where each electron in the system is regarded as point charge and observed through the system from Cathode to Anode. A space charge limited emission process is simulated. Low voltage sufficies to create large electric field across the vacuum diode …
