1. 1. Modeling and Compensation of Nonlinear Distortion in High Efficient Electrodynamic Loudspeakers

   University essay from Luleå tekniska universitet/Signaler och system

   Author : Caroline Holmström; [2020]
   Keywords : ;

   Abstract : Loudspeakers transform electrical energy into acoustic waves but most of the electrical energy is lost as heat. It is possible to increase the electro-acoustic efficiency by changing the electrical, mechanical or acoustical design of the loudspeaker but with these changes come unwanted side effects. READ MORE

3. 2. Challenging cultural identities : Between new forms of tourism and old European cities

   University essay from Uppsala universitet/Teologiska institutionen

   Author : Wester Wagenaar; [2016]
   Keywords : contents tourism; Europe; heritage; identity; popular culture;

   Abstract : New forms of tourism are on the rise where the incentive to travel is not primarily induced by a country’s heritage, but by mediatized narratives, characters and locations starring in products such as movies, comics and literature. This so-called contents tourism is considered promising by some, but the question is: who benefits? Europe is often understood as the old continent, a place with a rich history. READ MORE

4. 3. Behavioral Modeling of Power Amplifier with Memory Effect and Linearization Using Digital Pre Distortion

   University essay from Högskolan i Gävle/Elektronik

   Author : Om Prakash Nandi; [2016]
   Keywords : Behavioral Modeling; Power Amplifier; DPD;

   Abstract : This thesis work studied the behavioral modeling, estimation of parameters, model performance and linearization of power amplifier (PA) using Digital Pre Distortion (DPD) technique. PAs are one of the fundamental block in communication systems and also one of the main sources of nonlinearities in the system, as these devices are frequently subjected to signals characterized by considerable bandwidths and non-constant envelopes due to use of modern modulation technique.

5. 4. Different Digital Predistortion Techniques for Power Amplifier Linearization

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Ibrahim Can Sezgin; [2016]
   Keywords : DPD; Digital Predistortion; Forward Behavioral Modeling; Power Amplifier; Non-Linearity; Memory Effect; Volterra Series; Memory Polynomial; Generalized Memory Polynomial; Simplified Volterra Series; Augmented Complexity Reduced Generalized Memory Polynomial; Augmented Complexity Reduced Simplified Volterra; Technology and Engineering;

   Abstract : Linearity and high efficiency are crucial requirements for any power amplifier. However, power amplifiers have high efficiency levels when they are in non-linear regions. To overcome this issue there have been many suggestions in literature, one of the most successful methods is digital predistortion method. READ MORE

6. 5. Methods of Modelling Corrugators

   University essay from Lunds universitet/Förpackningslogistik

   Author : Gunilla Nordström; [2001]
   Keywords : Corrugated board; Corrugator; ; Modelling; Parametric models; ; Non-parametric models; ; possibilities of studying loss of fibre strength; Technological sciences; Teknik; Technology and Engineering;

   Abstract : Problem: The process of manufacturing corrugated board is a quite complicated process, when it comes to exactly understand what happens in the process. ln order to gain a better understanding and a tool for control of the corrugating process, the machine making the corrugated board, a method that possibly can describe the process is desirable.
