I. Problem Description
The assembly line scheduling problem is as follows:
The colonel automobile company produces cars in factories with two assembly lines. After a chassis enters each assembly line, different components are installed on the chassis of each Assembly station, the finished car leaves the end of the assembly line. As shown in 1.
Figure 1 assembly line
There are n assembly stations on each as
Today, we still need to use an excellent chassis to assemble an ultra-large capacity server-only a 1U high eight hard disk massive storage server, with a single hard disk capacity of 250 GB and a total disk capacity of 2 tb2000g )! The things I assembled may not be really NAS. The definition of the real NAS is too complicated. Many places do not comply with the definition of the official ocean. As long as this things can store massive amounts of infor

Since 05, SUV sales have grown steadily, and by the end of last year domestic SUVs accounted for the second largest car rankings. Modern to the SUV pro-gaze, then at home and abroad major automakers are competing in the fierce competition in the Chinese market, how to choose a suitable car? Learn the following points, absolutely enough!First of all, the selection of SUVs has to look at four important basic information. See Fuel consumptionBefore you buy a car, consider the cost of raising a car
Visitor-Visitor ModePurposeWithout changing the classes in a hierarchy, define new operations that act on each element of the class.CaseThere are different device Equipment, such as Chassis and FloppyDisk. Some people want to know its performance, but some want to know its price, and some may want to know other information, such as manufacturer and manufacturing materials. However, when an Equipment class is defined and a subclass is defined, you need
motherboard temperature is too high reason and solution:
50 more normal, games, etc. in 60, or even 70 degrees (occasionally), generally more than fifty or sixty degrees that should take measures to dissipate heat.
1. Your motherboard temperature monitoring failure (sensor damage) caused, the temperature does not change.
2. Your host box internal cooling performance is too poor, fan aging and other factors caused.
3.CPU model problem: If the processor for Pentium D, especially the Pentium D8
, if the type of software often run in summer does not have a good fan sound high temperature must be normal.
The main way to dissipate heat is by increasing the motherboard heatsink and chassis fan.
Additional motherboard temperature high reason and solution:
Cause the motherboard temperature is too high for the following reasons:
1, inside the chassis and the mother
, Serial ATA due to the use of point-to-point way to transmit data, so only need 4 lines to complete the send and receive function, plus the other three ground, a total of only 7 physical connection to meet the needs of data transmission. Due to the low transmission data lines, SATA in the physical circuit of the electrical performance of the interference greatly reduced, which also ensures the future disk transmission rate further upgrade.Compared to parallel ATA, the data cable of Serial ATA i

In layman's parlance, the video card is equivalent to the human eye, without which the computer will not be able to drive the display screen.

Large-screen LCD TVs are already very popular in the family, however, only to watch TV, and there is no big entertainment, first of all, can not play online games, the other TV movies and TV programs are not rich in the network, so many home users will be matching a HTPC host to meet the network rich audio-visual and game entertainment needs, The combination of Super large screen LCD display, entertaining is very good. For everyone to recommend a balanced performance and fashion appearance of th

If the optical drive is damaged internally, it can also cause the host to start slowly or fail the self-test, or it may suddenly restart during operation. In the latter case, if we replace the optical drive after the appearance, it is likely that the optical drive power consumption caused by different. What you need to understand is that although the ATPI interface of the optical drive is the same, but different manufacturers of the PIN definition is not the same, if we have a pr

I am reading Apple's 2012 WWDC, and I have read it in half. I want to write out my most practical feelings.
First of all, this Conference may not be inferior to the previous one, because I have never seen it before. At that time, there was still a helper, and now it is a cook who is trying to imitate the Lord. I will not comment on these two people, but only on how I feel about Apple.
Apple has released a series of products that let people talk about it. We have never seen this configuration in

It also has 2.4GHz of Quad core Intel Core I7-3630QM processors, 16GB memory, and nvidia GeForce GTX 670M (3GB Independent video memory) hardware portfolio, although the overall performance is not the strongest, However, some major 3D games can still be addressed. On the storage side, the 750GB SATA hard drive +256GB solid-state drives are packaged in storage space and provide a faster storage speed. In a sense, Asus G75VW-DH72 can be said to be an all
Today, the main character is the chassis. Many hardware firewalls are just PCs with multiple NICs. They only use UNIX operating systems and have customized a special chassis-a box, which is worth hundreds of times. The magic box that makes PC accessories worth hundreds of times is a 1U steel shell firewall chassis.
Today, I chose a Firewall Router professional 1
