Strong Interactions in Spacelike and Timelike Domains: Dispersive Approach provides the theoretical basis for the description of the strong interactions in the spacelike and timelike domains. The book primarily focuses on the hadronic vacuum polarization function, R-ratio of electron-positron annihilation into hadrons, and the Adler function, which govern a variety of the strong interaction processes at various energy scales. Specifically, the book presents the essentials of the dispersion relations for these functions, recaps their perturbative calculation, and delineates the dispersively improved perturbation theory. The book also elucidates the peculiarities of the continuation of the spacelike perturbative results into the timelike domain, which is indispensable for the studies of electron-positron annihilation into hadrons and the related processes.

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 !
