Abstract:
Networks distribute energy, materials and information to the components of a variety of natural and human-engineered systems, including organisms, brains, the Internet and microprocessors. Distribution networks enable the integrated and coordinated functioning of these systems, and they also constrain their design. The similar hierarchical branching networks observed in organisms and microprocessors are striking, given that the structure of organisms has evolved via natural selection, while microprocessors are designed by engineers. Metabolic scaling theory (MST) shows that the rate at which networks deliver energy to an organism is proportional to its mass raised to the 3/4 power. We show that computational systems are also characterized by nonlinear network scaling and use MST principles to characterize how information networks scale, focusing on how MST predicts properties of clock distribution networks in microprocessors. The MST equations are modified to account for variation in the size and density of transistors and terminal wires in microprocessors. Based on the scaling of the clock distribution network, we predict a set of trade-offs and performance properties that scale with chip size and the number of transistors. However, there are systematic deviations between power requirements on microprocessors and predictions derived directly from MST. These deviations are addressed by augmenting the model to account for decentralized flow in some microprocessor networks (e.g. in logic networks). More generally, we hypothesize a set of constraints between the size, power and performance of networked information systems including transistors on chips, hosts on the Internet and neurons in the brain.

Abstract:
In communication and communication devices, power equipment, relay protection and automation terminals, in the electric power industry of "smart" cities and homes, in industry, in railway transport, microprocessor-based relay protection and automation devices, distributed generation installations, including renewable energy sources, and electricity storage, as well as "intelligent" automated information and measurement systems are beginning to be used. Contactless converters of direct and alternating currents of control and control systems are widely used in them. Their disadvantages are a narrow range of controlled currents, large dimensions and weight. Therefore, it is important to eliminate them. The paper discusses the general principles of construction of contactless converters of large direct currents, the main requirements for them, and shows the results of the development of one of the options proposed by us, universal contactless magneto-modulation converters of large direct currents with an extended range for various control and control systems. They differ from the known ones by an extended controlled range with small dimensions and weight, and increased accuracy and sensitivity. The converter has a simple and technological design with low material consumption and cost, and can control large direct currents, as well as alternating currents, without contact. The paper considers the errors from external magnetic fields of universal contactless converters of control and control systems. It is shown that the error from the external magnetic field does not exceed 0.08% if the number of sections of the measuring winding is even and with their symmetrical arrangement, and with their even increase-the error decreases. At the same time, the developed contactless converters can be widely used in industry, metallurgy, railway transport, agriculture, water and farming, as well as in the electric power industry of “smart” cities and homes and for checking electric meters at the place of their installation.

Abstract:
Personal computers (PCs) dominate today’s digital landscape. The two-letter name started with the 1981 IBM PC. Desktop machines based on single-chip microprocessors—and thus called microcomputers—were widely used before the IBM PC, but that is the name that has stuck. Many would consider a Packard-Bell tabletop computer of the early 1960s to be the first personal computer. But as far as single-user/operator commercial machines go, there is also the Bendix G15 from the mid-1950s, described in Chapter 9. PC users are likely to have forgotten or never known the atmosphere of early-generation computers. The ‘operating system’ was a schedule for the human staff who mounted large reels of tape, toggled inputs at the long control panel, pushed the load-and-run switch, and stacked punch cards and fanfold sheets of printed output. The numerous operators wore white lab jackets, worked in large air-conditioned spaces, and appeared to be high priests and acolytes in a vocational order. The users were supplicants. Apart from experimental machines at universities—such as MIT’s famed TX-0 (1955–6), which was controlled by the first computer hackers once it moved to the MIT campus in 1958—the users entreated the operators through written requests heading a card deck. Back then, the users as well as the general public stood behind a velvet rope, even a window wall. The operators continued to rule the machine long after users had electronic connection through time-sharing remote terminals. But those who had hacked the small machines like the TX-0 knew that the goal was the direct, immediate access of personal computers. Colossus already had that personal touch. Designed to be used by a single cryptanalyst assisted by one Wren, and later often run by the Wren solo, Colossus was in that sense a personal computer. But just how close was Colossus to being a PC? This chapter compares and contrasts the architecture of Colossus with that of today’s personal computers. An architect designs a building by balancing needs and functions with resources and aesthetics. The availability and cost of components constrain her work. Physical limitations and dynamics of use further impact on it. The building reflects the architect’s imagination and skill.

Abstract:
Combustor development depends on two important factors, namely combustor efficiency and exit temperature profile. A microprocessor based system has been designed to have on-line display of exit temperature profiles during the development testing of a gas turbine engine. The system acquires temperature data from thirty thermocouples around the circumference and at various radial positions of the engine. The signals from the thermocouples are fed to a microprocessor through an analog input subsystem. The microprocessor computes the temperatures, averages the values and plots the radial profile on a colour graphic terminal. On the colour graphic terminal, ideal temperature profiles for various engine speeds are drawn. On the ideal temperature profile, actual temperature profiles are superimposed for various speeds during the testing of a gas turbine engine. In addition, circumferential profile is also plotted in off-line.

Abstract:
The Port Authority Trans-Hudson (PATH) heavy-rail rapid-transit system has a two-decade history of using microprocessor-based equipment as replacements for electromechanical and electrical systems. Until recently, these processors were used for non-vital applications only, such as event recording and train dispatching. With the rebuilding of the World Trade Center terminal, processors were introduced for vital applications. PATH is now in the midst of a processor-based replacement of its entire signal system. Here we present a review of past, current and future applications of processor-based equipment at PATH. We examine the reasons for conversion and the advantages and disadvantages for design, installation and maintenance. A survey is made of equipment that is removed, added, replaced or retained for processor-based conversion. Interfacing with field appliances, including the continued use of relays for limited applications, is examined. With so much functionality concentrated within a single piece of equipment, new types of failure modes and redundancy become important considerations, as well as the volatility of critical information needed to maintain service. We also expose the problems of testing and cutover of new equipment on a railroad that operates passenger service 24 hours a day, 365 days a year, and training requirements of signal office staff and field forces. Since PATH is under FRA jurisdiction, use of processor-based equipment for vital applications is subject to additional regulations and we look at the programming accommodations for FRA testing.
