<p>This thesis investigates passively mode-locked semiconductor lasers by numerical methods. The understanding and optimization of such devices is crucial to the advancement of technologies such as optical data communication and dual comb spectroscopy. The focus of the thesis is therefore on the development of efficient numerical models, which are able both to perform larger parameter studies and to provide quantitative predictions. Along with that, visualization and evaluation techniques for the rich spatio-temporal laser dynamics are developed; these facilitate the physical interpretation of the observed features.</p> <p>The investigations in this thesis revolve around two specific semiconductor devices, namely a monolithically integrated three-section tapered quantum-dot laser and a V-shaped external cavity laser. In both cases, the simulations closely tie in with experimental results, which have been obtained in collaboration with the TU Darmstadt and the ETH Zurich. Based on the successful numerical reproduction of the experimental findings, the emission dynamics of both lasers can be understood in terms of the cavity geometry and the active medium dynamics. The latter, in particular, highlights the value of the developed simulation tools, since the fast charge-carrier dynamics are generally not experimentally accessible during mode-locking operation. Lastly, the numerical models are used to perform laser design explorations and thus to derive recommendations for further optimizations.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。 19,447円 税込 送料込 カードOK 楽天Kobo電子書籍ストア ![]() | ||

<p>This Springerbrief presents a deep reinforcement learning approach to wireless systems to improve system performance. Particularly, deep reinforcement learning approach is used in cache-enabled opportunistic interference alignment wireless networks and mobile social networks. Simulation results with different network parameters are presented to show the effectiveness of the proposed scheme.</p> <p>There is a phenomenal burst of research activities in artificial intelligence, deep reinforcement learning and wireless systems. Deep reinforcement learning has been successfully used to solve many practical problems. For example, Google DeepMind adopts this method on several artificial intelligent projects with big data (e.g., AlphaGo), and gets quite good results..</p> <p>Graduate students in electrical and computer engineering, as well as computer science will find this brief useful as a study guide. Researchers, engineers, computer scientists, programmers, and policy makers will also find this brief to be a useful tool.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。 7,292円 税込 送料込 カードOK 楽天Kobo電子書籍ストア ![]() | ||

<p><strong>An updated overview of plant root systems, covering their development, growth, interactions with soil, breeding and management</strong></p> <p><em>Plant Roots</em> draws together information from plant and soil literature to illustrate how roots interact with soil, both to modify it and to obtain from it the resources required for the whole plant to grow. Emphasis is placed on whole plants and root systems, with appropriate references to the growing body of literature on plant molecular and cellular levels.</p> <p>This newly revised and updated Second Edition maintains its balance between introducing the founding ideas and science underlying the topic while covering the most recent updates underpinned by new scientific methods and understanding. The author reviews recent advances in genomics, phenomics, other -omics technologies, computer modelling, and the study of ‘model plants’ such as <em>Arabidopsis thaliana</em> and rice which have led to major advances in understanding how roots grow and function. New crop varieties contributing to increased crop production, especially in nutrient poor and/or water-limited soils, are described together with new ways of managing root systems to improve crop performance and efficiency of resource use.</p> <p>Sample topics discussed in <em>Plant Roots</em> include:</p> <ul> <li>The anatomy and growth of primary roots</li> <li>The development and properties of the rhizosphere</li> <li>Heterogeneity of structure, nutrient availability, and microbial communities experienced in field soils</li> <li>Differences in anatomy and morphology between different types (classes) of root and their consequences for activity as absorbers of water and nutrients</li> <li>How crops, forests, natural plant communities and the resources supporting them might be managed more effectively</li> </ul> <p><em>Plant Roots</em> is an essential source of reference aimed at students and professionals who already have some background knowledge of soils and plants and are seeking to understand cutting-edge updates in the field.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。 34,114円 税込 送料込 カードOK 楽天Kobo電子書籍ストア ![]() | ||

<p>It could be argued that the influence of Lacan on modern literary studies has been greater than anyone’s. Lacan has historicised the universal or mythic perceptions of Freud, and thus lent a new status to literature as a cultural artefact. This book, originally published in 1986, aims to delineate the trends in the uses made of Lacan today; to examine the theoretical substructure by which his work is accommodated to literature; and to analyse the way in which his work ‘models’ the formal relation of the literary text to other texts, to history and to politics.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。 9,767円 税込 送料込 カードOK 楽天Kobo電子書籍ストア ![]() | ||
