  • The library TB-SYMKEYS 2.2 helps you create HMI applications with flow charts efficiently, e.g. for water management applications. The new library supports both GT and GN terminals. For GT panels, this product contains a floating icon library and four key libraries which can be integrated into GTWIN. For the GN series, this product contains sample projects for Movicon with all symbols. Each symbol functions as a button that can open a new page, switch equipment directly, or just as call up info.

  • This ninth edition was introduced to bring the material up-to-date and to render all of the diagrams to the same standard. Some of the information from previous editions has been left out; either because it was obsolete or because it is not relevant to modern electronics. Most students are taught discrete component circuit analysis and design with silicon npn transistors as the main active devices. Although a flexibility of approach is important (i.e.

  • All geographic information systems (GIS) are built using formal models that describe how things are located in space. A formal model is an abstract and well-defined system of concepts. It defines the vocabulary that we can use to describe and reason about things. A geographic data model defines the vocabulary for describing and reasoning about the things that are located on the earth. Geographic data models serve as the foundation on which all geographic information systems are built. We are all familiar with one model for geographic information—the map.

  • Chapter 6 - Developing data models for business databases. Chapter 5 explained the Crow's Foot notation for entity relationship diagrams. You learned about diagram symbols, relationship patterns, generalization hierarchies, and rules for consistency and completeness. Understanding the notation is a prerequisite for applying it to represent business databases. This chapter explains the development of data models for business databases using the Crow's Foot notation and rules to convert ERDs to table designs.

  • Machine control design is a unique area of engineering that requires the knowledge of certain specific and unique diagramming techniques called ladder diagramming. Although there are similarities between control diagrams and electronic diagrams, many of the component symbols and layout formats are different. This chapter provides a study of the fundamentals of developing, drawing and understanding ladder diagrams.

  • Power riser diagram for a combined office-warehouse building. the motor it will control. The contactors, overcurrent protective devices, transformer, and operating coil are in one enclosure, and the start/stop pushbuttons are in a separate enclosure so that they can be mounted some distance from the motor. In this schematic each component is represented by a graphic symbol, and each wire is shown making individual connections between the devices. However, multiple wires could appear as one line on the drawing.

  • The following is an e-text of "Chess Strategy," second edition, (1915) by Edward Lasker, translated by J. Du Mont. This e-text contains the 167 chess and checkers board game diagrams appearing in the original book, all in the form of ASCII line drawings. The following is a key to the diagrams: For chess pieces, R = Rook Kt = Knight B = Bishop Q = Queen K = King P = Pawn Black pieces have a # symbol to the left of them, while white pieces have a ^ symbol to the left of them. For example, .#B is the...
