TL;DR: One that the authors will refer to break the boredom in reading is choosing state space theory of discrete linear control as the reading material.
Abstract: Introducing a new hobby for other people may inspire them to join with you. Reading, as one of mutual hobby, is considered as the very easy hobby to do. But, many people are not interested in this hobby. Why? Boring is the reason of why. However, this feel actually can deal with the book and time of you reading. Yeah, one that we will refer to break the boredom in reading is choosing state space theory of discrete linear control as the reading material.

TL;DR: A general purpose data acquisition and analysis system for the VAX 11/780 that runs under VMS and uses commercially available hardware for the bulk of the interface and is written almost exclusively in Fortran.
Abstract: We have described a general purpose data acquisition and analysis system for the VAX 11/780. The system runs under VMS and uses commercially available hardware for the bulk of the interface. The code is written almost exclusively in Fortran and uses many software components and ideas from other laboratories. All users share common versions of applications tasks, reducing problems associated with program proliferation and documentation.All event sorting is performed by the event analysis language EVAL. Singles data rates of about 70 KHz use about a third of the available CPU time. This has little or no impact on the response time for the other off-line users. Taking over work from an other facility is a convenient and fast way of implementing a data acquisition system when the computer and interface are identical. This was the case for us with the MBD software and the graphics software. If the hardware configuration is different, however, implementation may be difficult unless one of the programmers is very familiar with the system being installed. The key parts of our system, EVAL and the Z-like data structures, did require modification. They were developed during a three month visit by one of the authors (RVP). Once these foundations were laid, the work of writing the full system could be spread around a number of people. We estimate about 1.5 man years of effort in our system to date.

TL;DR: High level control programs which allow the operator to examine and control the transport lines and rings in terms of beam and machine parameters using mathematical models of the system.
Abstract: The control system for the National Synchrotron Light Source is implemented using dual central computers and many remote microprocessors. This paper describes developments in four areas: 1) System organization. 2) Hardware status, particularly control desk and operator support facilities. 3) Central computer software system organization to support data base structures and access, and communication between application programs and hardware. 4) High level control programs which allow the operator to examine and control the transport lines and rings in terms of beam and machine parameters using mathematical models of the system. The output of these programs can be viewed on a color graphical display.

TL;DR: The traditional subjects of electric machinery, i.e., transformers, dc machines, induction machines, and synchronous machines, are thoroughly covered without resorting to many complicated electromagnetic field theorems and equations.
Abstract: This is indeed a welcome addition to the set of several exciting introductory books on electromechanical energy conversion devices. It is a well-suited text for an introductory course for electrical engineering students with interest in power systems. The traditional subjects of electric machinery, i.e., transformers, dc machines, induction machines, and synchronous machines, are thoroughly covered without resorting to many complicated electromagnetic field theorems and equations. Many numerical examples demonstrate the theory and principles set forth in the text; the abundance of excellent figures, diagrams, and actual pictures serves to illustrate the important concepts. For the benefit of the students interested in control theory, simple dynamic analyses of several machines, using the sdomain techniques, are presented at the end of selected chapters. The book consists of seven chapters and four appendices. Chapters 1-4 cover transformers, dc machines, three phase system theory, and induction motors, respectively. The chapter on dc machines also contains analog simulation and CSMP programs for descniing the dynamics of a dc machine under different excitations. The remaining chapters are dedicated to synchronous machines. Elementary synchronous machines and measurement of three-phase synchronous devices are topics of Chapters 5 and 7, respectively. Systems considerations of synchronous machines are covered in Chapter 6. Topics such as connection to an infinite bus, excitation systems, parallel operations, dynamic analysis, and swing equations are presented in this chapter. Consistent with the statement at the preface, the author presents material useful to students in control systems. Since stepping motors are used in a variety of control systems application, a section covering the theory, controls, and applications of these motors would have been a valuable addition to the book. The general organization of the book is reasonable in terms of both overall coverage and chapter headings. Each chapter includes a summary, a set of homework problems and a reference list. The text can be used in a two-semester course for electrical engineering students with a major in power systems. However, proper selection of the material in the text allows one to design a onesemester course in electric machine theory.

TL;DR: The ever present and expanding need for displaying visual information in such locations as banks, airports, department stores and other businesses has led to the rapid expansion of the market for information display devices.
Abstract: The ever present and expanding need for displaying visual information in such locations as banks, airports, department stores and other businesses has led to the rapid expansion of the market for information display devices. In addition, the expansion of the home computer, teletext, and electronic automotive markets will lead to a need for low-cost information display devices. Currently, the most widely used display device (where a large volume of data must be displayed simultaneously) is the CRT terminal.

TL;DR: A laboratory for the multi-processor environment is described herein where more than one DSP application can be implemented at different times by hardware reconfiguration through host software commands.
Abstract: A laboratory for the multi-processor environment is described herein where more than one DSP application can be implemented at different times by hardware reconfiguration through host software commands. This environment has evolved from the development of several real-time applications on our research signal processors. The applications involve from one to five processors, a host, a bulk storage display device, and also analog hardware for analog signal interaction. All applications are loadable from the host, with host control required for the loading of programs and the initialization of data. However, no host intervention is usually required during the operation of most real-time applications. Examples of one-processor to five-processor applications in several DSP areas (speech, image processing, spectral analysis, and modems) are presented with emphasis on the flexibility of the hardware configuration.

TL;DR: A new engineering technique has been devised to improve the planning and implementation of mobile-radio projects, which comprises the following stages: application of digitized topographic data to compute HF and VHF propagation in various ways.
Abstract: A new engineering technique has been devised to improve the planning and implementation of mobile-radio projects. A specially developed SYMBL computer program is used in conjunction with this technique, which comprises the following stages: • Application of digitized topographic data to compute HF and VHF propagation in various ways. • Collection of radio propagation data along predetermined roads. • Standardization of base station antenna mountings from antenna pattern measurements taken in situ using a helicopter. The two latter stages, which provide feedback for the first, will be analyzed in a later paper, the emphasis here being on the software application in stage one.
