Advances in Non-Linear Modeling for Speech Processing (SpringerBriefs in Speech Technology)
by Mangesh S. Deshpande Raghunath S. HolambeAdvances in Non-Linear Modeling for Speech Processing includes advanced topics in non-linear estimation and modeling techniques along with their applications to speaker recognition. Non-linear aeroacoustic modeling approach is used to estimate the important fine-structure speech events, which are not revealed by the short time Fourier transform (STFT). This aeroacostic modeling approach provides the impetus for the high resolution Teager energy operator (TEO). This operator is characterized by a time resolution that can track rapid signal energy changes within a glottal cycle. The cepstral features like linear prediction cepstral coefficients (LPCC) and mel frequency cepstral coefficients (MFCC) are computed from the magnitude spectrum of the speech frame and the phase spectra is neglected. To overcome the problem of neglecting the phase spectra, the speech production system can be represented as an amplitude modulation-frequency modulation (AM-FM) model. To demodulate the speech signal, to estimation the amplitude envelope and instantaneous frequency components, the energy separation algorithm (ESA) and the Hilbert transform demodulation (HTD) algorithm are discussed. Different features derived using above non-linear modeling techniques are used to develop a speaker identification system. Finally, it is shown that, the fusion of speech production and speech perception mechanisms can lead to a robust feature set.

The Psychology of Totalitarianism
by Mattias DesmetThe world is in the grips of mass formation—a dangerous, collective type of hypnosis—as we bear witness to loneliness, free-floating anxiety, and fear giving way to censorship, loss of privacy, and surrendered freedoms. It is all spurred by a singular, focused crisis narrative that forbids dissident views and relies on destructive groupthink. Desmet’s work on mass formation theory was brought to the world’s attention on The Joe Rogan Experience and in major alternative news outlets around the globe. Read this book to get beyond the sound bites! Totalitarianism is not a coincidence and does not form in a vacuum. It arises from a collective psychosis that has followed a predictable script throughout history, its formation gaining strength and speed with each generation—from the Jacobins to the Nazis and Stalinists—as technology advances. Governments, mass media, and other mechanized forces use fear, loneliness, and isolation to demoralize populations and exert control, persuading large groups of people to act against their own interests, always with destructive results. In The Psychology of Totalitarianism, world-renowned Professor of Clinical Psychology Mattias Desmet deconstructs the societal conditions that allow this collective psychosis to take hold. By looking at our current situation and identifying the phenomenon of “mass formation”—a type of collective hypnosis—he clearly illustrates how close we are to surrendering to totalitarian regimes. With detailed analyses, examples, and results from years of research, Desmet lays out the steps that lead toward mass formation, including: An overall sense of loneliness and lack of social connections and bonds A lack of meaning—unsatisfying “bullsh*t jobs” that don’t offer purpose Free-floating anxiety and discontent that arise from loneliness and lack of meaning Manifestation of frustration and aggression from anxiety Emergence of a consistent narrative from government officials, mass media, etc., that exploits and channels frustration and anxiety In addition to clear psychological analysis—and building on Hannah Arendt’s essential work on totalitarianism, The Origins of Totalitarianism—Desmet offers a sharp critique of the cultural “groupthink” that existed prior to the pandemic and advanced during the COVID crisis. He cautions against the dangers of our current societal landscape, media consumption, and reliance on manipulative technologies and then offers simple solutions—both individual and collective—to prevent the willing sacrifice of our freedoms. “We can honor the right to freedom of expression and the right to self-determination without feeling threatened by each other,” Desmet writes. “But there is a point where we must stop losing ourselves in the crowd to experience meaning and connection. That is the point where the winter of totalitarianism gives way to a spring of life.” “Desmet has an . . . important take on everything that’s happening in the world right now.”—Aubrey Marcus, podcast host “[Desmet] is waking a lot of people up to the dangerous place we are now with a brilliant distillation of how we ended up here.”—Robert F. Kennedy, Jr.

Lies of Omission: Algorithms versus Democracy
by Catherine DeSotoA lie of omission—withholding needed information to correct a false belief. There is a sharp and more hostile divide emerging in the United States. The shift is documented by various polls, and the speed of the change is alarming. There are certainly contributing factors, but one factor is unique to the contemporary era: receiving the majority of our information via social media experiences. Media algorithms, and to some extent overt censorship, serve users curated content that is unlike what their neighbors receive.Lies of Omission brings together various perspectives on the causes and effects of the divided information streams. Psychology and neuroscience, combined with some historical jurisprudence, are woven together to spell out the dangers of the modern social media experience. Importantly, the human response can be understood as rooted in our psychology and neurochemistry. In part two of the book, eight hot button issues that have provoked deep divisions among American citizens are presented as well-researched, opposing-view chapters with a goal to lay bare the extent of the disinformation gap that we are living in. With the rise of ephemeral smart media, and the associated displacement of the permanently printed word, it is rare to have a clear idea of what persons who do not share our opinions actually believe, or why.The decimation of communal information sources is nearly complete. What can one do? One concrete step is to turn some of your attention away from curated, impermanent news and read a book. Read this book. Dr. Catherine DeSoto spells out why it is worth our time to be informed regarding the issues we care about: something your phone&’s curated media will never do for you. Open your mind to the quaint idea that one is not informed unless one understands the opposing view. Surprising all-new research regarding the political divide and the pandemic is included. Together with over 150 references, this book will be the definitive source documenting the effects of the media algorithm revolution.

Talking to Artists / Talking to Programmers: How to Get Programmers and Artists Communicating
by Wendy DespainArtists and programmers often work together on complex projects in stressful environments and things don’t always go smoothly. Miscommunication and misunderstandings are common as these two disciplines often use the same words to mean different things when they talk to each other. Unintentional slights can turn into long-held grudges and productivity grinds to a crawl. This is a "flip book" that contains two narratives in one. Turn the book one way and read one perspective; turn the book over and upside down and read the other perspective. The narratives can be read separately, one after the other, or in alternating chapters. Talking to Artists / Talking to Programmers can help anyone who wants to improve communication with artists and programmers. It’s set up like a foreign language dictionary, so it addresses the cultural norms, attitudes and customs surrounding the words each group uses, so you’ll know not just what the words in the glossary mean, you’ll know why they’re used that way and how to get communication flowing again. It addresses common reasons for communication problems between these two groups and provides specific suggestions for solutions. The unusual format allows for each side to be given equal weight - learn how to talk to artists starting on one side of the book, turn it over and learn how to talk to programmers. The whole book stresses the things artists and programmers have in common. Focused primarily on videogame developers, it also applies to other fields where tech and art have to work together, including web developers and teams building mobile apps. Anyone who wants to communicate better with programmers or artists - this book can help Features Lists of common problems and strategies for solving them Specific ideas for building bridges between departments Case studies from real teams Glossary of terms causing the most confusion Explanations for common friction points Approaches for fostering goodwill Solutions for team dynamics problems Specific suggestions for providing feedback Ideas for holding successful meetings

Thermal Stability of Metastable Magnetic Skyrmions (Springer Theses)
by Louise DesplatThe energy cost associated with modern information technologies has been increasing exponentially over time, stimulating the search for alternative information storage and processing devices. Magnetic skyrmions are solitonic nanometer-scale quasiparticles whose unique topological properties can be thought of as that of a Mobius strip. Skyrmions are envisioned as information carriers in novel information processing and storage devices with low power consumption and high information density. As such, they could contribute to solving the energy challenge.In order to be used in applications, isolated skyrmions must be thermally stable at the scale of years. In this work, their stability is studied through two main approaches: the Kramers' method in the form of Langer's theory, and the forward flux sampling method. Good agreement is found between the two methods. We find that small skyrmions possess low internal energy barriers, but are stabilized by a large activation entropy. This is a direct consequence of the existence of stable modes of deformation of the skyrmion. Additionally, frustrated exchange that arises at some transition metal interfaces leads to new collapse paths in the form of the partial nucleation of the corresponding antiparticle, as merons and antimerons.
