  • The aim of this book is to provide readers with a fundamental understanding of digital system concepts such as logic gates for combinatorial logic circuit design and higher level logic elements such as counters and multiplexers. First year undergraduates taking a course in computer science or engineering (and related disciplines like information technology) are the main target audience. Foundation year students and those taking pre-university courses (like ‘A’ levels) will also benefit from the text. I have tried to follow a simple approach in writing the text.

  • Focusing on the rich biodiversity of Costa Rica, the contributors demonstrate the use of geographic information systems (GIS) to enhance conservation efforts. They give an overview of the spatial nature of conservation and management and the current status of digital mapping in Costa Rica; a review of the basic principles behind digital mapping technologies; a series of case studies using these technologies at a variety of scales and for a range of conservation and management activities; and the results of the Costa Rican gap analysis project....

  • Ground vehicles can navigate using signals from external navigation systems such as the Global Positioning System (GPS) (Figure 1.1), or by using signals from internal devices such as a compass, an odometer, a gyroscope, an accelerometer, or a full-blown inertial navigation system (INS). In practice, the most reliable and accurate navigation is obtained by combining data from all available sources, including static databases such as a digitized map. This chapter will discuss many of these sources of navigation data, and methods for combining them....

  • Digital Fundamentals is irrelevant: AC . It may appear tempting to create a product term consisting of the three boxes on the bottom edge of the K-map. This is not valid because it does not result in all boxes sharing a common product relationship, and therefore violates the power-of-two rule mentioned previously. Upon completing the K-map, all product terms are summed to yield a final and simplified Boolean equation that relates the input variables and the output: Y = B + AC . Functions of four variables are just as easy to solve using a K-map. Beyond four variables, it is...

  • The focus of this chapter is on inverse problems — what they are, where they manifest themselves in the realm of digital signal processing (DSP), and how they might be “solved1 .” Inverse problems deal with estimating hidden causes, such as a set of transmitted symbols ftg, given observable effects such as a set of received symbols frg and a system (H) responsible for mapping ftg into frg. Inverse problems are succinctly stated using vector-space notation and take the form of

  • Abstract. A pair of ‘trust maps’ give a fine-grained view of an agent’s accumulated, time-discounted belief that the enactment of commitments by another agent will be in-line with what was promised, and that the observed agent will act in a way that respects the confidentiality of previously passed information. The structure of these maps is defined in terms of a categorisation of utterances and the ontology. Various summary measures are then applied to these maps to give a succinct view of trust....

  • A synthetic aperture radar (SAR) is a radar sensor that provides azimuth resolution superior to that achievable with its real beam by synthesizing a long aperture using platform motion. The geometry for the production of the SAR image is shown in Fig. 33.1. The SAR is used to generate an electromagnetic map of the surface of the earth from an airborne or spaceborne platform. This electromagnetic map of the surface

  • For some time now, movie marketing has expanded its boundaries beyond discrete paratexts such as posters, TV ads, trailers, or featurettes, and into such publicity-driven entities such as “Entertainment News” shows, actual news segments covering movie premieres or milestones, and other nebulous promotional venues. The digital environment accelerates such embedments and boundary-crossings. Marketing becomes an increasingly elusive and crucial subject for film historians interested in ecologies of cinematic knowledge.

  • In order to synthesize automat (in this case digital counters), the minimizing internal states is of particular significance and plays a decisive role in the results of synthetic circuit. This can be done in many ways, but the use of Karnaugh map is considered optimal. However, this process has some disadvantages that it can not be overcome when the number of input variants is large. In experience, if the number of variants is 7, manual minimization of circuit functions using Karnaugh map arises many difficulties and even become impossible if over 10 variants are available.
