  • 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.

  • A function block diagram (FBD) is a block diagram that describes a function between input variables and output variables. A function is described as a set of elementary blocks. Input and output variables are connected to blocks by connection lines. An output of a block may also be connected to an input of another block

  • A PLC or programmable controller is a computer based solid state device that controls industrial equipment and processes. Initially designed to perform the logic functions executed by relays, drum switches and mechanical timer/counters, it has been extended to analog control as well. A typical PLC system consists of a processor and an input/output system all mounted in a rack like system. The PLC system is a cost effective solution for applications with a high ratio of digital to analog points in a system.

  • Making the Nation Safer: The Role of Science and Technology in Countering Terrorism, a report released by the National Academies in June 2002,1 articulated the role of science and technology in countering terrorism. That report included material on the specific role of information technology (IT). Building on that report as a point of departure, the panel of experts responsible for the IT material in Making the Nation Safer was reconvened as the Committee on the Role of Information Technology in Responding to Terrorism in order to develop the present report....

  • Chart the sequence of stages and steps to reflect the intrinsic and architectural dependencies inherent in the project. An output or product of one task will usually be the input to another, and this will be the primary driver in determining the task dependencies and workflow. Determine whether the successor task references (throughput) or updates (entry requirement) the input product. Some inputs may be sourced from outside the project. Identify these External Inputs (e.g., Long Range System Plan, Standards, Project Initiation report of another project, etc.).

  • People with disabilities continue to face architectural barriers that limit or make it impossible to access the goods or services offered by businesses. Examples include a parking space with no access aisle to allow deployment of a van’s wheelchair lift, steps at a facility’s entrance or within its serving or selling space, aisles too narrow to accommodate mobility devices, counters that are too high, or restrooms that are simply too small to use with a mobility device.

  • One of the most striking developments in European Union law has been the growth of EU measures in the field of criminal law. The increasingly assertive presence of the Union in this field raises profound questions about national sovereignty, the relationship between the individual and the state and the role of the European Union. As an expression of the coercive powers of the State, criminal law is perceived to fall par excellence within the province of national sovereignty. There is no historical precedent of building a supra-national system of criminal law.

  • Countering this, a second group points to the high and possibly still rising unemployment in the U.S. and Europe, coupled with excess capacity, as an effective barrier to any near-term outbreak of inflation in 2009—or even 2010. In the aggregate, they see potential supply still looking much higher than demand. This group worries that any withdrawal of stimulus now would be premature—much as in the Great Depression, when U.S. fiscal and monetary retrenchment in 1937 cut short a nascent economic recovery after 1933.

  • Despite all the skepticism, the ‘old savings’ bonds turned out to be the perfect opportunity for the development of financial market in Serbia. This was a new and liquid security that carried virtually no risk for its holders. However, for a number of reasons, the bond market became distorted, dividing into primary and secondary markets, with the secondary market further segmented into over-the-counter and stock exchange markets.
