The authors provide a comprehensive analysis on the model predictive control of power converters employed in a wide variety of variable-speed wind energy conversion systems (WECS). The contents of this book includes an overview of wind energy system configurations, power converters for variable-speed WECS, digital control techniques, MPC, modeling of power converters and wind generators for MPC design. Other topics include the mapping of continuous-time models to discrete-time models by various exact, approximate, and quasi-exact discretization methods, modeling and control of wind turbine grid-side two-level and multilevel voltage source converters. The authors also focus on the MPC of several power converter configurations for full variable-speed permanent magnet synchronous generator based WECS, squirrel-cage induction generator based WECS, and semi-variable-speed doubly fed induction generator based WECS.

We are considering a future redesign of our premises. Our objective is to offer more ergonomic workspaces, adapted to the needs of our users.

That is why we are conducting a survey. From August 20th to September 6th 2019, please complete the online questionnaire: http://cern.ch/go/6LL9

Since early summer, our team has been considering the question: how do we improve the physical spaces of the library? We have reviewed state-of-the-art libraries and started collecting your opinions through a brainstorming wall and interviews within the library. 

Now we would like even more points of view on, for instance, the furniture that would suit you best, the electrical outlets you need or even how brightly lit the room should be.

The survey will not take you more than 10 minutes. Whether you are a regular user or only come to the Library occasionally, we are interested in your opinion.

The answers to the questionnaire are of course anonymous and confidential. We will not collect your personal data.

If you have any questions, please contact us at this address: library.desk@cern.ch.

Thank you in advance for your participation !

August 1987 – “Cosmic Song” by Serge Moro

In 1985 CERN commissioned a monumental mosaic for its new reception building, Serge Moro’s “Cosmic Song”, which was completed in 1987. This photo shows the scale of the artwork, and a more dramatic picture of the swirling colours and shapes was captured by the July/August CERN Courier (p. 31).

 

The metal and plexiglass flooring, built in collaboration with the CERN workshops, uses fluorescent light effects governed by the constant rain of cosmic ray particles from outer space. You can see it in action in the artist’s film clip.

New book

Measured by the accuracy of its predictions and the scope of its technological applications, quantum mechanics is one of the most successful theories in science--as well as one of the most misunderstood. The deeper meaning of quantum mechanics remains controversial almost a century after its invention. Providing a way past quantum theory's paradoxes and puzzles, QBism offers a strikingly new interpretation that opens up for the nonspecialist reader the profound implications of quantum mechanics for how we understand and interact with the world. Short for Quantum Bayesianism, QBism adapts many of the conventional features of quantum mechanics in light of a revised understanding of probability. Bayesian probability, unlike the standard "frequentist probability," is defined as a numerical measure of the degree of an observer's belief that a future event will occur or that a particular proposition is true. Bayesianism's advantages over frequentist probability are that it is applicable to singular events, its probability estimates can be updated based on acquisition of new information, and it can effortlessly include frequentist results. But perhaps most important, much of the weirdness associated with quantum theory--the idea that an atom can be in two places at once, or that signals can travel faster than the speed of light, or that Schrodinger's cat can be simultaneously dead and alive--dissolves under the lens of QBism. Using straightforward language without equations, Hans Christian von Baeyer clarifies the meaning of quantum mechanics in a commonsense way that suggests a new approach to physics in general.

July 1960 – Soviet visitors arrive at CERN

Following CERN’s decision in 1959 to welcome Soviet scientists, the first long-term visitors from beyond the iron curtain arrived on 18 July 1960 for a stay of six months.

 

Vladimir Meshcheryakov and Rostislav Ryndin, from the Theoretical Physics Laboratory in Dubna, joined CERN’s Theoretical Studies Division, where they continued to work on projects begun in the USSR, while experimentalist Yuri Sherbakov, also from Dubna, assisted in running the 600 MeV synchro-cyclotron. See the July 1960 CERN Courier  for more details.
