NYOJ 38 Wiring Problem _ (solution 1 Kruskal algorithm), nyojkruskal Time Limit: 1000 MS | memory limit: 65535 KB difficulty: 4 Description Nanyang institute of technology needs to transform the power line. The principal now asks the designer to design a wiring method which must meet the following requirements: 1. Power up all the buildings. 2. Minimum Cost of wires used Inpu

The line connection of the home theater is centered on the AV Power Amplifier. Its input end is connected to signal sources such as DVDs, CDs, and satellite receivers through a signal line. Its output end is connected to speakers, televisions, and projectors. Currently, the speaker system of the home theater system is generally dominated by 5.1. The connection diagram is as follows: As shown in, the two main speakers of the 5.1 speaker, one central speaker, and the superwoofer speaker are all p

The test of the optical cable cabling system is a necessary step for project acceptance. It is also the final process for the project contractor to honor the contract with the real estate owner. Only after the system test is passed can the cabling system be completed. The connectivity of devices is the most basic requirement for wiring system testing. The effectiveness of jumper systems can be easily tested. It is relatively difficult to test the indi

In the previous installments, we learned about the installation of the main parts of the chassis, but the installed process is not finished yet. Because there are still a lot of cables on the chassis panel, what are they doing? They are switches and LEDs, as well as PC speaker connections, which are connected to the motherboard. This is not a very simple matter, because these connections are more, and easy to mess up, but it is very painful to install. So today we're going to look at how to conn

With the development of commercial Office intelligent Building, in the network is not only the increasing demand for bandwidth, but in the face of endless network business, so the office building Yu on the network integrated access ability requirements have been improved. and the traditional building wiring scheme is not good enough to meet the needs of high-rise office buildings for integrated access network. There are a lot of active devices such as

integrated wiring system is annealed. Heat treatment is the process of manufacturing through a special heating process so that in a specific environment can reduce distortion and vibration stress. In the copper strand, some of the fine lines are double lines or multiple strands of lines together to form a single line. Hard conductor is easier to dry connection, the stranded wire is softer.

When it comes to data center improvement, the budget and plan are all facing challenges, as are network cabling and equipment. Technological innovation brings various challenges, especially when the data center is updated, it still needs to be maintained as usual. However, it is necessary to deploy important new technologies in the data center, which is also an opportunity to make the data center more efficient and energy-saving. In the process of data center transformation and upgrading, and

The Integrated Wiring System is the infrastructure of various buildings or residential buildings, it plays an important role in ensuring normal production activities, living, and public services. This article takes the Integrated Wiring System and monitoring system as an example to describe how to cooperate with each system. Various public facilities (such as water supply, drainage, electric power, gas, tel

Why do strong and weak current cables need to be separated? This is because there is a magnetic field around the strong current, if the strong current Weak CurrentWiring distanceWhen it is too close, it will affect the weak current signal. The specific manifestation is: if it is a cable TV line, the signal will not be very clear; if it is a telephone line, the phone will be noisy; if it is a network cable, the network transmission speed will be affected. Therefore, when

In the integrated wiring project, the installation of Information sockets must be as high, flat, and firm. There is an information module in the information outlet. There are two methods for information module crimping: 1) crimping with a threading tool. 2) directly crimping without the need for wire hitting tools. Based on engineering experience, the crimping module is generally used as a threading tool. The procedure of module crimping is as follows

Principle of stepper motor According to common sense, the wiring of stepper motor depends on the color of the wire. However, the color of the stepping motor produced by different companies is different. Especially foreign stepper motors. Then, the stepper motor wiring should be made with a multimeter. The internal structure of stepper motor is as follows: We can see that ,~ A is connected, B and ~ B i

really an old keyboard, there are a few keys are not good, but it will not affect the normal start Ah, simply, for a good try again, fault as usual, this can be trouble, how is it?There is no way, and then take off the board to come, and suddenly found that HD LED wire plug in the Keylock, the original Hisense computer chassis no reset button, plug wiring did not see clearly, it is customary to connect.
