High-Linearity CMOS RF Front-End Circuits
High-Linearity CMOS RF Front-End Circuits presents some unique techniques to enhance the linearity of both the receiver and transmitter. For example, using harmonic cancellation techniques, the linearity of the receiver front-end can be increased by few tens of dB with only minimal impact on the other circuit parameters. The new parallel class A&B power amplifier can not only increase the transmitter's output power in the linear range, but can also result in significant savings in power consumption. High-Linearity CMOS RF Front-End Circuits can be used as a textbook for graduate courses in RF CMOS design and will also be useful as a reference for the practicing engineer.

High-Level Modeling and Synthesis of Analog Integrated Systems
In High-Level Modeling and Synthesis of Analog Integrated Systems, two novel generic behavioral models are described. The first one adopts a time-domain approach and is suited for classes like Delta-Sigma modulators and sampled-data systems. For the second model, a new frequency-domain framework has been developed (the Phase- Frequency Transfer model) which allows the representation of classes of RF systems like front-ends of wireless receivers. To complete the high-level design strategy, the synthesis strategy has been concretized with a new top-down heterogeneous optimization algorithm.

Higher Education Landscape 2030 : A Trend Analysis Based on the AHEAD International Horizon Scanning
The digital transformation clearly highlights the role of universities and institutes of higher education in shaping a higher education system that is more open and provides education to everyone who can benefit from it
Higher Education and Graduate Employment in Europe : Results from Graduates Surveys from Twelve Countries
The book indicates a noteworthy variety among economically advanced countries in the competences fostered by Higher Education and the emphasis placed either on laying a broad basis of knowledge or direct preparation for professional tasks. While universities in some countries are strongly involved in ensuring a rapid transition from study to employment, in other countries a long period after graduation is widespread for the search of a suitable career. Graduates from some countries appreciate their study experiences though they criticize a weak preparation for their subsequent assignments, while others less satisfied with higher education in their retrospective view note a satisfying preparation for the world of work. Study often turns out useful to lead to challenging tasks even though remuneration and status remain below expectations.
High-Energy-Density Physics : Fundamentals, Inertial Fusion, and Experimental Astrophysics
The raw numbers of high-energy-density physics are amazing: shock waves at hundreds of km/s (approaching a million km per hour), temperatures of millions of degrees, and pressures that exceed 100 million atmospheres. This book introduces the reader to the fundamental tools and discoveries of high-energy-density physics. It surveys the production of high-energy-density conditions, the fundamental plasma and hydrodynamic models that can describe them and the problem of scaling from the laboratory to the cosmos. Connections to astrophysics are discussed throughout. The book is intended to support coursework in high-energy-density physics, to meet the needs of new researchers in this field, and also to serve as a useful reference on the fundamentals. Specifically the book has been designed to enable academics in physics, astrophysics, applied physics and engineering departments to provide in a single-course introduction to fluid mechanics and radiative transfer, with dramatic applications in the field of high-energy-density systems.

It provides a quantitative summary of the major issues to allow the assessment of the state of the art and a glimpse at future developments. Selected experts share their know-how and expectations in this rapidly evolving art related to the single most powerful of our senses.
High-dimensional chaotic and attractor systems : A comprehensive introduction
If we try to describe real world in mathematical terms, we will see that real life is very often a high–dimensional chaos. Sometimes, by ‘pushing hard’, we manage to make order out of it; yet sometimes, we need simply to accept our life as it is. To be able to still live successfully, we need tounderstand, predict, and ultimately control this high–dimensional chaotic dynamics of life. This is the main theme of the present book.
High Thermal Conductivity Materials
High thermal conductivity materials play an important role in addressing thermal management issues. This volume provides readers a basic understanding of the thermal conduction mechanisms in these materials and discusses how the thermal conductivity may be related to their crystal structures as well as microstructures developed as a result of their processing history. The techniques for accurate measurement of these properties on large as well as small scales have been reviewed. Detailed information on the thermal conductivity of diverse materials including aluminum nitride (AlN), silicon carbide (SiC), diamond, as well as carbon nanotubes has been presented. The emphasis is on developing basic understanding of the inter-relationships between thermal conductivity and processing such that the readers can conduct their own research in this exciting field of high thermal conductivity materials.

High Resolution Infrared Spectroscopy in Astronomy ; Proceedings of an ESO Workshop Held at Garching, Germany, 18-21 November 2003
Two specialized new instruments for ESO's VLT, VISIR and CRIRES, spawned the idea for this workshop. CRIRES is a dedicated very high resolution infrared spectrograph; VISIR features a high resolution spectroscopic mode. Together, the instruments combine the sensitivity of an 8m-telescope with the now well-established reliability of VLT-facility instruments. High resolution here means that lines in cool stellar atmospheres and HII-regions can be resolved. The astrophysical topics discussed in this rather specialized workshop range from the inner solar system to active galactic nuclei. There are many possibilities for new discoveries with these instruments, but the unique capability, which becomes available through high-resolution infrared spectroscopy, is the observation of molecular rotational-vibrational transitions in many astrophysical environments. Particularly interesting and surprising in this context, many papers on modeling and laboratory spectroscopy at the workshop appear to indicate that astronomical observations are lagging a bit behind in this field. The papers are an interesting mix of reports from existing high resolution facilities, reports on modeling efforts of synthetic spectra and reports on laboratory spectra. In this sense, a fruitful exchange between molecular physics and astronomy was again accomplished and is documented in this volume.
