The Origin of "Complex Tones". Multiphonic Sounds generated with Wine Glasses and Woodwind Instruments
Scientific Study from the year 2023 in the subject Physics - Acoustics, language: English, abstract: This study examines if wine glasses can generate multiphonic sounds as a result of a hit with a metal stick on the bowl of the wine glass (hit-excitation). It demonstrates that at least two Eigenfrequenzen (= natural frequencies) of the excited wine glasses with frequencies in Hz of "F1" and "F2" (with F2) will generate complex tones with frequencies in Hz of "F2+F1" and "F2-F1" - which is a typical characteristic of multiphonic sounds known from woodwind instruments. Based on the analysis of the decay kinetics of the Eigenfrequenzen and the complex tones after a hit-excitation of the wine glass, the hypothesis has been developed that the oscillations F1 and F2 build a power-profile which can be mathematically described as a multiplication of the amplitude-values of both oscillations and that this power-profile is the driving force to generate oscillations of some areas of the walls of the bowl of the wine glasses with the frequencies "F2-F1" and "F2+F1".

Thermal lens spectrometry using Gaussian and Laguerre Gaussian modes of excitation
Doctoral Thesis / Dissertation from the year 2022 in the subject Physics - Other, grade: PhD, language: English, abstract: This work presents a Thermal Lens spectrometry model based on Laguerre-Gaussian excitation of sample. We calculated refractive index and temperature gradient profiles and compare with the results obtained by fundamental Gaussian mode. Our results show remarkable change of the refractive index around propagation axis and an increase along radial direction that can be crucial for increasing the sensitivity of the technique. Furthermore a modified general dual beam Z-scan model and its exact solution have been presented. The comparison with the previous model of Z-scan has been briefly discussed. The dependence of pinhole size and sample to detector distance in Thermal Lense signal for Z-scan is critical, which was ignored in previous models. The experimental validity of the presented model for thermal diffusivity and absorption coefficient of distilled water is also part of our research work.

Russian Energy Strategy in the Asia-Pacific
Given Australia's lack of energy security strategy, it is not surprising that the country is void of institutional knowledge and know-how of Russian foreign energy strategy. The 'lucky country' as it were, relies entirely on sea-lines of communication to the north to supply fuel and to export Australian coal and natural gas. Australia has entered the 2020s as the world's largest liquefied natural gas (LNG) exporter; however, maintaining complacency in Canberra's current export activities will ultimately lead to a long-term security crisis. This book critically examines Russian energy strategy in the Asia-Pacific, with a view to determining the security implications for Australia. Russia is important for global energy security chains because of its vast resource wealth and its geographical position - a pivotal position to supply both the European and Asian markets. Australia has no such luxury, geographically constrained as an island continent; it relies on the nearby Asia-Pacific import market to demand our energy and to facilitate the delivery of our national oil supplies. Understanding Russian foreign energy strategy in the region is crucial given the growing energy requirements in Australia's emerging Asia-Pacific arena.

Spiral Progression Approach in Teaching Science (SPATS). Enhancing and Developing Science Skills
Academic Paper from the year 2023 in the subject Didactics - Physics, grade: 1,0, language: English, abstract: The main objective of this research study is to explain the experiences and challenges encountered by 25 secondary science teachers with the implementation of the Spiral Progression Approach in Teaching (SPAT). Thematic Analysis was used to analyze the information given by the respondents, which was gathered through informal interviews and focal group discussions. Spiral progression is an approach used to teach science and mathematics. It focuses on the understanding that human cognition evolved in a step-by-step process of learning, which relied on environmental interaction and experience to form intuition and knowledge. Under SPAT, students are exposed to authentic assessment instead of traditional classroom assessment, meaning that the tasks they perform relate to the real world and have a practical value. These tasks may include project based learning, performance task, portfolios, collaborative works and online examinations. The data gathered in the study serves as base line data for the constructive recommendation in accord with the response of the key informants. This research may be useful to other subject areas that also uses spiral progression in teaching.

Slopes and Levels
This book features an extensive index and all Mathcad worksheets. Vinyl is back, tubes/valves are back, on the high-end field SMD-free analog amplification surpasses digitalized chains, and top microphone manufacturers still set on good old op-amps or on fully discrete BJT, FET, and/or tube-driven amplifiers. There is only one problem that is not satisfyingly well solved by the manufacturers: It is the noise production of the active components and the useful reflection in simulation tools, in tables or graphs of the datasheets/data books. Nowadays, mostly surrounded by many digital helping tools, it makes sense using them--also by analog aficionados. It saves cost and time simulating first before spending money. Presented in this book the software tool LTSpice which is the free software solution from Linear Technology (today Analog Devices) that could also be used by full analog lovers to simulate the noise production of their amplifier design. All we need is the right creation approach to develop simulation models for the active components. Inter alia this is already done for tubes and BJTs in the 2nd editions of my "How to Gain Gain" and "Balanced Phono-Amps" books. For op-amps, the missing approaches are presented in the book on hand. It cannot be denied that mathematical software like Mathcad is extremely helpful to find the right equations for graphically presented noise curves which we can find in the literature. Nevertheless, it also works well with other types of math software to fulfill the parameter needs of the here presented modeling approaches for the input referred voltage and current noise of--not only--excellent sounding vintage op-amps, applicable in the audio range from 1 Hz to 100 kHz.

Stellar Structure and Evolution
Stellar Structure and Evolution, the second volume in the Ohio State Astrophysics Series, takes advantage of our new era of stellar astrophysics, in which modern techniques allow us to map the interiors of stars in unprecedented detail. This textbook for upper-level undergraduate and graduate students aims to develop a broad physical understanding of the fundamental principles that dictate stellar properties. The study of stellar evolution focuses on the 'life cycle' of stars: how they are born, how they live, and how they die. As elements ejected by one generation of stars are incorporated into the next generation, stellar evolution is intertwined with the chemical evolution of our galaxy. Focusing on key physical processes without going into encyclopedic depth, the authors present stellar evolution in a contemporary context, including phenomena such as pulsations, mass loss, binary interactions, and rotation, which contribute to our understanding of stars.
Rich Quasiparticle Properties in Layered Graphene-Related Systems
This comprehensive book delves into the fascinating world of quasiparticle properties of graphene-related materials. The authors thoroughly explore the intricate effects of intrinsic and extrinsic interactions on the material's properties, while unifying the single-particle and many-particle properties through the development of a theoretical framework. The book covers a wide range of research topics, including long-range Coulomb interactions, dynamic charge density waves, Friedel oscillations and plasmon excitations, as well as optical reflection and transmission spectra of thin films. Also it highlights the crucial roles of inelastic Coulomb scattering and optical scattering in the quasiparticle properties of layered systems, and the impact of crystal symmetry, number of layers, and stacking configuration on their uniqueness. Furthermore, the authors explore the topological properties of quasiparticles, including 2D time-reversal-symmetry protected topological insulators with quantum spin Hall effect, and rhombohedral graphite with Dirac nodal lines. Meanwhile, the book examines the gate potential application for creating topological localized states and shows topological invariants of 2D Dirac fermions, and binary Z2 topological invariants under chiral symmetry. The calculated results are consistent with the present experimental observations, establishing it as a valuable resource for individuals interested in the quasiparticle properties of novel materials.
Case Studies in Star Formation
Case Studies in Star Formation offers an overview of our current observational and theoretical understanding in the molecular astronomy of star formation.

UFOs
Unidentified phenomena in space, in the Earth's atmosphere, and in waters are too important to leave their exploration to the military and scientific laypersons. Their proper scientific study is important for a variety of reasons; in particular, scientists and the public at large need to know the basic facts, to be informed about the way evidence is recorded, and to understand the difference been reliable evidence and fiction, as well as between plausible explanations and fantasy.With this objective, the book surveys the history of UFO observations, the variety of recorded phenomena, and recounts the efforts of investigative commissions and their published findings. Although wild rumors are demystified in the process, this is not an exercise in rumor-bashing. An open and at the same time critical mindset is the key. Many narratives and hypothesis appear implausible relative to our present state of knowledge; but this alone should not lead to their outright exclusion. Thus the author also pays attention to UFO sightings that have so far eluded explanation in terms of known physics or meteorology. Here the reader will encounter some of the more speculative but scientifically tenable proposals, for example, relating to sudden zigzag motion without apparent inertia or recognizable propulsion, yet always with a clear guide to their plausibility. Last but not least, the book outlines plans and suggestions for future research capable of revealing the existence and intentions of extraterrestrial intelligences, outer-space engineers, or technologies so far known only from science fiction.

Star Noise: Discovering the Radio Universe
Until Karl Jansky's 1933 discovery of radio noise from the Milky Way, astronomy was limited to observation by visible light. Radio astronomy opened a new window on the Universe, leading to the discovery of quasars, pulsars, the cosmic microwave background, electrical storms on Jupiter, the first extrasolar planets, and many other unexpected and unanticipated phenomena. Theory generally played little or no role - or even pointed in the wrong direction. Some discoveries came as a result of military or industrial activities, some from academic research intended for other purposes, some from simply looking with a new technique. Often it was the right person, in the right place, at the right time, doing the right thing - or sometimes the wrong thing. Star Noise tells the story of these discoveries, the men and women who made them, the circumstances which enabled them, and the surprising ways in which real-life scientific research works.

Quantum Phases of Matter
This modern text describes the remarkable developments in quantum condensed matter physics following the experimental discoveries of quantum Hall effects and high temperature superconductivity in the 1980s. After a review of the phases of matter amenable to an independent particle description, entangled phases of matter are described in an accessible and unified manner. The concepts of fractionalization and emergent gauge fields are introduced using the simplest resonating valence bond insulator with an energy gap, the Z2 spin liquid. Concepts in band topology and the parton method are then combined to obtain a large variety of experimentally relevant gapped states. Correlated metallic states are described, beginning with a discussion of the Kondo effect on magnetic impurities in metals. Metals without quasiparticle excitations are introduced using the Sachdev-Ye-Kitaev model, followed by a discussion of critical Fermi surfaces and strange metals. Numerous end-of-chapter problems expand readers' comprehension and reinforce key concepts.
