Quasiconformal Groups
… Schottky quasiconformal groups and show that the limit set L(G) of any Schottky quasi-conformal group G is uniformly perfect. Then the concept of Schottky-type quasiconformal groups is introduced, and we generalize our results about Schottky quasiconformal groups to the new setting. We prove that …

A Classification of Kupka-Smale Flows on the Torus
… of such flows in the case that they possess a limit set which is neither a singular point nor a closed orbit.

Boundaries and hierarchically hyperbolic spaces
… of Teichmuller space. In fact, we prove that the limit set can be almost anything allowed by the topology.

Examples and Applications of Infinite Iterated Function Systems
… we investigate some properties of a limit set J associated to such system, its Hausdorff and packing measure and Hausdorff dimension. We provide necessary and sufficient conditions for such systems to be bi-Lipschitz equivalent. We use the concept of scaling functions to obtain some …

Self-rolled-up membrane (S-RuM) capacitors and filters for radio frequency communication
… and break the footprint and parasitic effect limit set by conventional planar devices. S-RuM inductors and capacitors can reach self- resonant frequency up to 60 GHz, Q factor up to 80, and with footprint one hundredth that of the state- of-the-art 2D counterparts. This thesis illustrates the …

Generation and Measurement of Entangled Atomic Ensembles with an Optical Cavity
Atomic interferometers have a resolution limit set by the projection noise in measurements on ensembles of uncorrelated atoms. To overcome this classical limit and extend precision measurements into the quantum regime, we need to generate complex entangled states of large atomic ensembles and …

Neural Networks For Phase Demodulation In Optical Interferometry
… with sensitivities that achieve the fundamental limit given by the Cramér-Rao bound (CRB). As an application, we consider a particular QPI technique known as wavelength shifting interferometry (WSI) which obtains the OPL by acquiring multiple interferograms at different, evenly spaced …

20,000 Fewer: The Wagner-Rogers Bill and the Jewish Refugee Crisis
… York and Representative Edith Rogers of Massachusetts and introduced in February 1939, sought to allow the entry of 20,000 refugee children from Germany. At the time, multiple domestic factors limited the willingness of American politicians to meet this problem head on: high unemployment rates …

Neutron Emission Following Nuclear Muon Capture in Al
… of four orders of magnitude beyond the current limit set by the SINDRUM II collaboration. Achieving this sensitivity requires a thorough understanding of the backgrounds and competing interactions. Therefore, the AlCap collaboration was formed to study particle emissions from μ− + Al-27 → νμ + M …

An investigation of Turbo Codes over Mobile Wireless Channels
… producing results very close to the theoretical limit set by Shannon. The codes have been successfully implemented in satellite and video conferencing systems and provision has been made in 3rd generation mobile systems. These codes have not been used for short frame systems due to the delay at …

Cavity-enabled spin squeezing for a quantum-enhanced atomic clock
… atomic clocks has stood at the standard quantum limit, set by the projection noise inherent in measurements on ensembles of uncorrelated particles. Here, I demonstrate an atomic clock that surpasses this limit by operating with atoms in a particular type of entangled state called a "squeezed spin …

Objective evaluation of lean meat yield and EUROP scores for Icelandic lamb carcasses by video image analysis
… and 73% for fat which is within the minimum limit set by the Icelandic authorities. The heritability for VIAscan® yield prediction as proportions was generally high, ranging from 0.39 to 0.63,lowest for Shldr% and highest for Loin%. Heritability of viaEUROPc was 0.32 and 0.29 of viaEUROPf …

Tire Modeling and Friction Estimation
… vehicle in a safer way. The physical traction limit set by the friction between the tires and the road can, however, not be overridden. The behavior of tires is, therefore, an important issue since it determines the possibilities to control the vehicle. One essential task for the vehicle …

The Electrochemical Characterisation of Carbon-based Nanomaterials and their Application in the Detection of Heavy Metal Ions
… modified simply with pristine MWCNTs gave a limit of detection of 1.95 × 10-4 M with reasonable selectivity in the detection of Cr(VI) using cyclic voltammetry. To further enhance the sensitivity of detection, various alterations were made to the construction of the electrode including the …

Radiation Studies Of The Tin-doped Microscopic Droplet Laser Plasma Light Source Specific To Euv Lithography
… 100 ìm, is safely within the etendue limit set by the optical elements in the EUV scanner. Finally, the notion of irradiating the target with multiple laser beams was explored for the possibility of improving the source's conversion efficiency.

Electronic Mitigation of Polarization Mode Dispersion
… as a very attractive solution to overcome the limit set by the PMD. Consequently, we considered the implementation of these solutions at the receiver in the electrical domain. We verified that these linear and non-linear equalization techniques can greatly reduce the power penalty due to PMD. …

A new approach to Kneser's theorem on asymptotic density
… the analysis through the introduction of maximal sets, the basic sequence of maximal e-transformations, and the limit set, B*, is presented. For two sets of non-negative integers, A and B, with C∈A⋂B, the maximal sets, Aᴹ and Bᴹ, are the largest supersets of A and B, respectively, such that Aᴹ + …
