Action to be taken:Do not touch the casualty with hands.Break the electrical circuit by switching off or removing the plug from the socket.If this is not possible, immediately break the casualty’s contact with the supply by standing on dry insulating material and – using dry wood, a folded newspaper or a rubber object – push the casualty out of contact with the supply.Treat burns.Apply respiratory resuscitation if breathing has stopped.Apply cardiac massage if the heart has stopped. Ensure that there is no heartbeat before commencing this procedure.
Power Connectors
Published in Paul G. Slade, Electrical Contacts, 2017
This type of connector is intended for quick electrical engagement and disengagement of electrical or electronic units. The most important requirement imposed on this type of connector is the maintenance of satisfactory operation when operative or inoperative over various periods of time. Plug-and-socket connectors basically comprise contact base and contact-finish materials. Material selection for these devices is based on electrical (conductivity), mechanical (rigidity, flexibility) and contact force deflection characteristics, and on contact design. There is a wide variety of the plug-and-socket types of connector, the most common being jacks, pins, rack and panel connectors, IC sockets, printed-circuit edge connectors and terminal boards (See Chapter 6, Sections 6.2 and 6.3).

Examples include the following: Fixtures or jigs are used to position parts to make assembly easy. The assembled parts are removed and the jigs are used repeatedly. This concept is applied in the home as well as in the factory—a baking pan or a gelatin mold is an “intermediary” for shaping a dessert, and a pot holder is an intermediary for carrying a hot dish to the table without burning the server’s hands.A cable, or wireless system, is an intermediary between a computer and the Internet.A power cord and plug are an intermediary between the electrical grid and an electrical appliance or lamp.Ice can be used to hold small components in place temporarily if they will not be harmed by water when the ice melts. See also the earlier example of fixing carrot seeds on tape.A neutral third party can be used as an intermediary during difficult negotiations. For sales promotion, an intermediary, who is seen by the customer as an impartial expert, can make recommendations.

Ota et al. [77] have developed an independently distributed control strategy for V2G. The system also deals with centralized V2G as a secondary control scheme combined with the primary control. The load frequency control scheme based-SOC is designed to handle the scheduled charging of plug-out and plug-in idle time of the vehicle. In [78], an adaptive droop control scheme to deal with charging frequency regulation by applying innovative grid technologies is developed. This strategy aims to coordinate the charging schedule’s improvement and regulate the V2G frequency in real time. Notably, effective coordination of the vehicle charging system also improves the integration of DEG [79]. Therefore, the designed model in [78] is under the decentralized V2G strategy to participate in primary frequency control. A power generation scheduling model based on a novel fuzzy logic control is presented in [80]. The performance index of the control strategy uses the SOC model to minimize the power from the utility grid. This strategy was developed for a plug-in hybrid EV connected to the electrical network. However, the model is not advanced enough to deal with peak shaving on the consumer side. A peak-shaving and valley-filling control scheme based-V2G system are designed in [81]. The objection function is developed to optimally handle connected EVs and target curve values system constraints.
The Los Alamos Computing Facility During the Manhattan Project
Published in Nuclear Technology, 2021
The process to carry out the linear interpolation required using three PCAM machines, the type-513 reproducing punch, the type-075 card sorter, and the type-601 multiplier. The programmers had to develop a flow sheet for the operators. A pseudo flow sheet for the linear interpolation is shown in Table II. There were 11 steps, as explicitly shown in Table II, but three more implicit operations were needed to manually move the cards between the reproducer, sorter, and multiplier. But how did the multiplier know what to do with card 3? Figure 12 shows the plug board for the type-601 multiplier that controlled the operation of the machine. The programmers had to develop a plug board wiring diagram to tell the operators how to wire the plug board. The wiring diagram for the linear interpolation is shown in Fig. 13. The bottom-left connection of “Brushes” 11 to “X-1” shows that if column 11, row 0 on the card is punched, then this plug board operation was activated. The top row [labeled “f(n)” and “f(n + 1)”] shows that argument “a” was on columns 25 to 30 and “b” was on columns 35 to 40. The wiring diagram then showed the process to carry out the rest of the operations, as shown in Table II. The operators received the flow diagram and wiring diagram, wired the machines, and then moved the cards between machines as required. This process obviously became a nontrivial choreography for solving the hydrodynamic equations.

The test samples were prepared from woven e-textiles designed for EIOTV. Figure 1 shows a prepared test sample 4.5 with characteristics labeled (A-F). Areas for resistance measurement are also marked in the figure as (G and H). All test samples share the same characteristics as sample 4.5 pictured in Figure 1. In Figure 1: (A) Trace of Network A. (B) Trace of Network B. (C) Center weld points, two weld points per trace. The center weld points were not connected to the data acquisition (DAQ) system. (D) Main weld points that connect the test wire to the trace, two weld points per each end of trace are applied. Four weld points in total form the conductive network and enable compatibility with the DAQ system. (E) Location where the pin plug is soldered to the test wire. After being soldered, a heat shrink tube is added to protect the connection point. (F) Pin plug that connects to the test lead cable. (G) Represents total length of trace from which the resistance is measured. The resistance of this length is referred to as absolute resistance. (H) Represents the adjusted length of the resistance measurement. The resistance of this length is referred to as adjusted resistance.
