-time annotations, which we can access with Java reflection, and the purpose of run-time annotations is usually to provide instructions to programs and Third-party APIs. Annotation Basics A simple Java annotation resembles the @entity. Where @ means to tell the compiler that this is an annotation. And entity is the name of the annotation. Usually in the document, the following is written Public @interface Entity {} annotation element Java annotations can use elements to set values that

Global locks should be used on data structures The easiest way to make data thread safe is to put it on a large lock. For the sake of simplicity, all things are locked with the same lock. There is a problem with this approach: serialization. In order to get a lock, each thread that handles data must be queued. If the thread is blocked by a lock, it is not doing anything useful. This problem is not common when the server is lighter, because only one thread at a time may require a lock. In heavy l

Actually this also count ~ ~ #include Test Effect screenshot: Can see for simple scene test, the test effect is also good, the speed is very fast, dozens of frames per second, almost all can be correctly detected, but for complex point scene detection effect is very bad. This is the time to look at the depth of learning. Test Scenario 1: Highways, fewer targets, 1700 sequence pictures (320*240), only need about 25s. This is the scene under the monitoring camera of

/kg or so. It is understood that high-speed rail has a huge resource advantage has made the high-speed rail express as a strategic transition pedal. Last year, the China Railway Express in Jingguang Line, Beijing-Shanghai line on the pilot high-speed rail courier. Although in the pilot process, China Railway Express and Shun Fung, UPS and other foreign-funded courier enterprises to try to cooperate. Data show that before, the Canton Railway Group, Shenyang Railway Bureau, etc. have been low-key

signals to a combination (combine) into a string signal. Mapping and grouping are the most basic ways of signaling operations. We can see that my observation vehicle signal can be used many times, the vehicle signal as long as I produce once, everyone can use, they have no need to observe the vehicle, as long as the focus on their own task on the line, to avoid duplication of labor. This means that the signal can be used many times, the mapping or combination operation is to generate a new sign

thread at a time may require a lock. In heavy loads, a fierce scramble for locks could be a big problem. Imagine an accident on a multiple-lane highway where all the vehicles on the freeway were diverted to a narrow road. If there are few vehicles, the effect of this conversion on the rate of traffic flow can be ignored. If there are many vehicles, traffic jams

All objects in JavaScript are objects. This refers to objects in the traditional sense, that is, "a single entity that contains state and behavior ". For example, an array in JavaScript contains several values and contains objects of the push, reverse, and pop methods ....,. Please forget all the object-oriented knowledge you have learned before. Here you only need to consider the situation of racing cars. Yes, it's a racing car. Recently, I was watching 24 Hours of Le Mans, a popular competit

three parking spaces in the parking lot, all three parking spaces are empty at the beginning.At this time, if there are five vehicles at the same time, the gatekeeper will allow three of them to enter without hindrance, and then put down the car, and the remaining cars will have to wait at the entrance, since then, all the cars have to wait at the entrance.. At this time,A car leaves the parking lot. When the gatekeeper learns, he opens the car and p

this thing is actually everywhere. The factory that manufactures power sockets and the factory that manufactures electrical appliances only need to agree on an interface-two or three sockets, of course, interfaces in different countries are different, and the conversion between different interfaces requires an adapter. In fact, the same is true in the program. For example, all transportation tools can be abstracted as an interface Drivable (I may not think well due to experience ), indicates th

Wireless sensor networks have excellent characteristics and can provide an effective means for information collection of intelligent transportation systems. They can monitor vehicles in all directions at intersections. According to the monitoring results, simplified and improved signal control algorithms to improve traffic efficiency. Wireless sensor networks can be used in the con

1,A VANET Routing basedon the Rea l time Road Vehicle Density in the city environment, Hyun Yu, Joo n Yoo, Sanghyun Ahn. Icufn.In this vanet routing protocol, each vehicle uses beacon information and road imformation table to calculate the real-time vehicle density information for a particular route. Based on real-time vehicle density information, each vehicle can establish a reliable route for packet delivery. Specifically, each vehicle periodically sends a beacons packet, and the beacons inclu
