, landing gear can be retractable design into the mainstream. The number of engines has changed from one to two. With the improvement of the performance and the increase of processing information, the operation requirements of pilots become more and more high.Let's take a look at how the aircraft designer handled it more than half a century ago.

structured data in a format that allows JavaScript to navigate easily without XML processing expenses. Fortunately, there is a format that does exist.JavaScript Object AnnotationsIn fact, most of the JavaScript objects are composed of union arrays, numeric indexed arrays, strings, numbers, or nested sets of these types. Because all types can be declared directly with JavaScript, you can statically define the object graph in a single statement. Listing 7 declares an object using JSON syntax and

speed and slowness indicate the sound level. There is a very important relationship between sound harmony and frequency ratio,For example, the frequency ratio of octal is, the full five degrees is, and the big three degrees are ..., Basically, the number is restored.The smaller the proportion, the more harmonious it is called just intonation ). However, in a big three-degree cycleFor example, if you drop A, C, E, and # G, dropping a and # G will not become octal, but slightly different. To solv
1. What is DICOM?DICOM, short for digital imaging and communication of medicine, is an American College of radiology (ACR) and National Electrical Manufacturers Association (SCN) the Organization's standard name specifically for the storage and transmission of medical images. After more than a decade of development, this standard has been widely accepted by medical equipment manufacturers and the medical industry and has been widely used in medical instrumen
evaporation device, which is generally assembled by the evaporator dish, iron frame, alcohol lamp, glass rod and other instruments. Note: The liquid added to the evaporator should not exceed 2/3 of the volume of the evaporator. During the heating process, the glass rod should be used to keep the Glue Rod to prevent the splash of drops due to the high local temperature; close to before steaming should stop heating, the use of residual heat to the comp
Recently, I was working on a project about the tr component automatic testing system, in which I wanted to use IVI to set the testing system and instrument. Most of the new instruments support LAN ports, manufacturers all come with their own IVI drivers. As long as you follow the specified steps, you can implement IVI instrument settings for multiple manufacturers to achieve interchangeable similar instruments

Musical instrument recordingRecently, I have seen a lot of books related to recording studio. The question of traditional instruments and electronic musical instruments that bothered me before. For example, how much difference does an electric piano play with a piano? For example, what is the difference between the sound of an electronic violin and a violin? Simply put, you can hear the difference by standi

Article very good, excerpted from:http://www.codeceo.com/article/xcode-instruments-ios-memory.htmlAlthough the arc mechanism was added after iOS 5.0, a memory leak might exist due to the complexity of the mutual reference relationship. So it's important to understand the principle.Here's how to use instruments to find memory leaks in programs and use nszombieenabled settings without arc.This article assumes
to improve speedI can write an entire article about instruments. Here I will give you a general introduction because it will be very helpful.If you are not very experienced with instruments, I advise you to spend some time on weekends to study some. When you want to measure memory and time consumption, they will help you a great favor. However, when you start to make an app you will encounter a lot of prob

The previous design of Apple was a historical reason. In the early years, when the system received Memory Warning, Viewcontroller's View will be unLoad off. At this point, it is useful to use the weak view variable to keep the memory from being recycled. However, this design has been deprecated, and the alternative is to calayer the corresponding Cabackingstore type of memory area of the relevant view into a volatile type, as described in "Goodbye, Viewdidunload method".

In the industrial control test system, often need to use all kinds of programmed instruments, these programmed instruments usually have GPIB, LAN, USB and other hardware interface, the computer through these interfaces can communicate with, so as to achieve automatic measurement, data acquisition, analysis and processing operations.

1: Picture Memory Size Summary
A: Picture: Is the memory of the large, especially mobile game pictures of many resources. The calculation of the memory footprint of picture resources becomes the regular work of J2ME game developers, Cocomo to explain how to calculate the footprint of a picture in memory: memory footprint = width * High * pixel bytes, where the number of pixel bytes varies depending on the model.
For example, the memory footprint of a 64*64 picture on 7210 is =64

Space flight plan problems
Problem description
Professor W is planning a series of space flights for the National Space Center. Each space flight can carry out a series of commercial experiments to make profits. An available experiment set E = {E1, E2 ,..., Em}, and the set of all the instruments required to perform these experiments I = {I1, I2 ,... In }. The instrument used in the experiment J is a subset of I rj in I. The cost of configuring the
