This thesis concerns itself with relative primality of integers. It uses the concept of totatives, that is, integers relatively prime to a fixed number n, to investigate the distribution and products of those integers. The thesis presents two sufficient conditions for uniform distribution of totatives, a composite analogy of Wilson's theorem, and some results on partial products, including suf
This report investigates the gas-cooling effects of compressed air foam (CAF). A literature review has been made on the subject and on related issues in order to gather information. Two experimental series were conducted, the first to evaluate the gas-cooling properties of CAF compared to water. The other one was conducted to investigate how the recommended tactic, with application from a safe dis
With the advent of rodent models of l-DOPA-induced dyskinesia (LID), a growing literature has linked molecular changes in the striatum to the development and expression of abnormal involuntary movements. Changes in information processing at the striatal level are assumed to impact on the activity of downstream basal ganglia nuclei, which in turn influence brain-wide networks, but very little is ac
The leverage effect is one of two main hypotheses explaining the negative relationship between volatility of returns and return on equity. It states that a decrease in leverage, due for example to rising stock prices, increases the amount of equity which carries the firm volatility and thus decreases the volatility on rates of return. Using 51 companies that have been actively traded on the Stockh
Reinforcement learning in robotics is extremely challenging due to many practical issues, including safety, mechanical constraints, and wear and tear. Typically, these issues are not considered in the machine learning literature. One crucial problem in applying reinforcement learning in the real world is Safe Exploration, which requires physical and safety constraints satisfaction throughout the l
We predict an unexplored type of ultrastrong coupling between atoms and intense ultraviolet light that leads to giant population oscillations on the attosecond timescale. These counter-rotating oscillations stem from the interference of energy-conserving and nonconserving photon absorption and emission processes via Rydberg states. They can be of similar amplitude as the elementary femtosecond Rab
Double ionization following the absorption of a single photon is one of the most fundamental processes requiring interaction between electrons(1-3). Information about this interaction is usually obtained by detecting emitted particles without access to real-time dynamics. Here, attosecond light pulses(4,5), electron wave packet interferometry(6) and coincidence techniques(7) are combined to measur

The combustion and melt dripping of poly(ethylene-co-butyl acrylate) (EBA), EBA blended with polypropylene (EBAePP) and poly (ethylene-co-methacrylic acid) (EMAA), each blended with calcium carbonate and polydimethylsiloxane, were studied. In situ measurement of the temperature gradient in the cone calorimeter were combined with infrared spectroscopy measurements on specimens withdrawn and quenche

Since the early 1960s, the internationally acclaimed and highly distinguished Swedish geographer Gunnar Olsson has made substantial contributions to his own discipline. In addition, because of the transgressive nature of his work and writing, which often borders to art and philosophy, his ideas and approaches have reached a wider audience of those interested in the history and geography of ideas,
An antenna identity, derived from the forward scattering sum rule, shows that the partial realized gain of an antenna is related to the polarizability of the antenna structure. The partial realized gain contains the mismatch, directivity, efficiency, and polarization properties of the antenna. The antenna identity expresses how the performance depends on the electrical size and shape of the antenn
A stability criterion for nonlinear systems is presented and can be viewed as a dual to Lyapunov's second theorem. The criterion has a physical interpretation in terms of the stationary density of a substance that is generated in all points of the state space and flows along the system trajectories. If the stationary density is finite everywhere except at a singularity in the origin, then the syst

The spectral efficiency of a volume in a MIMO environment is analyzed. The analysis is based on a spherical mode expansion for the propagation, the radiation Q for the antennas, and Fano theory for the broadband matching
In this paper, we demonstrate that the existence of sequential equilibria may depend on the players holding beliefs which are tailored to the respective equilibrium but otherwise difficult to justify. We also discuss potential remedies. (C) 2011 Elsevier B.V. All rights reserved.
We introduce and analyze a new statistical ensemble of lowdensity parity-check convolutional (LDC) codes. The result of the analysis are bounds, such as a lower bound for the free distance and upper bounds for the burst error probability of the LDC codes.
