  • This book is called a ‘Guide to Geometric Algebra in Practice’. It is composed of chapters by experts in the field and was conceived during the AGACSE-2010 conference in Amsterdam. As you scan the contents, you will find that all chapters indeed use geometric algebra but that the term ‘practice’ means different things to different authors. As we discuss the various Parts below, we guide you through them. We will then see that appearances may deceive: some of the more theoretical looking chapters provide useful and practical techniques.

  • The discovery of infinite products byWallis and infinite series by Newton marked the beginning of the modern mathematical era. The use of series allowed Newton to find the area under a curve defined by any algebraic equation, an achievement completely beyond the earlier methods ofTorricelli, Fermat, and Pascal. The work of Newton and his contemporaries, including Leibniz and the Bernoullis, was concentrated in mathematical analysis and physics.

  • In general we do not like to wait. But reduction of the waiting time usually requires extra investments. To decide whether or not to invest, it is important to know the e ect of the investment on the waiting time. So we need models and techniques to analyse such situations.In this course we treat a number of elementary queueing models. Attention is paid to methods for the analysis of these models, and also to applications of queueing models.

  • In recent times, while markets are reaching their saturation limits and customers are be- coming more demanding, a paradigm shift has been taking place from mass production to customized mass production. The concept of customization focuses on satisfying a cus- tomer’s unique needs with the help of new technologies. Typically, the products are similar but they differ in some parameters which make manual teaching and manual preparation of the manufacturing programs not acceptable.

  • The purpose of this paper is to carry out the abelianization program proposed by Atiyah [1] and Hitchin [9] for the geometric quantization of SU(2) Wess-Zumino-Witten model. Let C be a Riemann surface of genus g. Let Mg be the moduli space of semi-stable rank 2 holomorphic vector bundles on C with trivial determinant. For a positive integer k, let Γ(Mg , Lk ) be the space of holomorphic sections of the k-th tensor product of the determinant line bundle L on Mg . An element of Γ(Mg , Lk ) is called a rank 2 theta function...

  • The field of photonics is enormously broad, covering everything from light sources to geometric and wave optics to fiber optics. Laser and light source technology is a subset of photonics whose importance is often underestimated. This book focuses on these technologies with a good degree of depth, without attempting to be overly broad and all-inclusive of various photonics concepts. For example, fiber optics is largely omitted in this book except when relevant, such as when fiber amplifiers are examined.

  • This intuitive yet rigourous introduction derives the core results of digital communication from first principles. Theory, rather than industry standards, motivates the engineering approaches, and key results are stated with all the required assumptions. The book emphasizes the geometric view, opening with the inner product, the matched filter for its computation, Parseval's theorem, the sampling theorem as an orthonormal expansion, the isometry between passband signals and their baseband representation, and the spectral-efficiency optimality of quadrature amplitude modulation (QAM).

  • According to our analysis, which included interviewing over 125 representative industry leaders in the region, the sector shows strong potential for growth across all dimensions: talent, which is affecting the creation of quality local content; content production, leveraging the expanding network of media free zones; consumption across traditional and new, digital platforms; and monetisation, through better targeting of audiences and new revenue streams. The industry is also expected to take advantage of the high proportion of young people in the Arab population.
