Ambient ZeroScatter: Ambient BPSK and QPSK Backscatter Communication using Existing Digital I/O Pins
… We additionally demonstrate a complete ambient backscatter communication system, consisting of the BPSK ZeroScatter tag, dipole antennas, and a direct sampling digital receiver. With an input clock frequency of 2.9 Gsps, the resolution of the receiver's analog-to-digital converter (ADC) …

Familiarization through Ambient Images Alone
<p>The term “ambient images” has begun to show up in much of the current literature on facial recognition. Ambient images refer to naturally occurring views of a face that captures the idiosyncratic ways in which a target face may vary (Ritchie & Burton, 2017). Much of the literature on ambient …

Sedimentation in a stratified ambient
… between settling particles and a stratified ambient in a variety of contexts. We first study the generation of large scale fluid motions by the localised release of a finite mass of particles in the form of plumes or gravity currents. We present the results of a combined theoretical and …

Structural damage detection using ambient vibrations
… objective of this research is to use structure ambient random vibration response to detect damage level and location. The use of ambient vibration is advantageous because excitation is caused by service conditions such as normal vehicle traffic on a highway bridge, train passage on a railroad …

Intraurban Variability of Ambient Particulate Matter
… of spatial and temporal variability in ambient particulate matter: PM) is important for effective air quality management and for assessing potential exposure misclassification in epidemiological and exposure studies used to support health-based standards. Spatiotemporal variability of PM …

Super-ambient temperature gas phase photocatalysis
<p class="MsoNormal">This thesis is concerned with the use of a continuous flow gas phase photocatalytic system to produce hydrogen as a cleaner fuel source. M/TiO2 photocatalysts (where M is Pt, Pd, Au and Ag) was used in a continuous flow gas phase photocatalytic system. Two main reactions were …

Particle formation in ambient mass spectrometry
A particle sizing system was developed that couples a light scattering particle sizer with a differential mobility analyzer for particle detection and elucidation with the capability for measuring particle sizes in the range of 10 nm to 20 μm. The particle sizing system was used to investigate …

Ambient vibration testing of concrete dams
… analysis (CVA)) have been applied to data from ambient vibration testing of two concrete dams namely; Roode Elsberg and Kouga dams.

The design of personal ambient displays
… thesis is to investigate the design of personal ambient displays. These are small, physical devices worn to display information to a person in a subtle, persistent, and private manner. They can be small enough to be carried in a pocket, worn as a watch, or even adorned like jewelry. In my …

Arbitrating modalities of interruption using ambient displays
… A multimodal interface explores the use of ambient displays in the context of interruption where visual and thermal ambient displays acted as external interruption generators. This works shows and demonstrates that interruption modalities are perceived differently, trigger different …

Characterization of bio-hybrid interfaces under ambient conditions
… (XPS) in ultra-high vacuum (UHV) and near-ambient-pressure (NAP) conditions were used for this investigation. Monochromatic X-ray 𝐴𝐴𝐴𝐴 𝐾𝐾𝐾𝐾 radi ation (ℎ𝜋𝜋 = 1486.7𝑒𝑒𝑉𝑉) was the exc itat ion source for the XPS experiments. The results obtained yielded information on the modifications …
