String In a given instance, any particular component is either undefined, or defined, and has a different value. Undefined string components are represented by null, and undefined integer components are represented by-1. The value of a defined string component can be an empty string, which is unequal to an undefined component. Whether a specific part of an instance is defined or undefined depends on the type of URI represented. An absolute URI has a scenario component. An opaque U

is that the school teachers speak more, the basic work is not used, and the teacher did not speak, or speak relatively little, the work is often used more. For example, in C language, the pointers, the structure of these, the school has little or no depth, we do not pay attention to, but to deal with the exam, but the work we need to always deal with them. Did you say you were a good study? This, in part, reflects the fact that there is a serious disconnect between school education and social

Optimization Check and determine whether there is room for improvement in the document results (such as project plans, requirement specifications, and design schemes) to achieve the best possible solution. There can be many different solutions for any design, and a best solution can be selected through "solution optimization. When designing a design, a designer always chooses what he thinks is the best solution, and there is a certain degree of "optimization ", therefore, he can say that his

function of mass in Newton mechanics that the matter is attributed to an object and the matter is regarded as an entity. Newton's definition of quality as a measure of "substance" is because in any mechanical movement, and even in chemical reactions, the quality is consistent. The quality is taken for granted as the absolute intrinsic nature of the material itself, and is regarded as the concrete manifestation of the principle of the matter being immortal or the entity invariable.The great succ

For most of the already skilled mathematics and physics workers, this is a very basic problem. But this problem has been bothering me for a long time when I first touched the tensor. So many definitions of tensor, what are the right ones? (Obviously, it's all right.) What are their relationships? I am as simple as I can in my own words to understand the superficial understanding of it. A View from Physics The concept of tensor was proposed by mathematicians at the end of the 19th c

When the economy is bad, people generally do not have any hobbies, so this time only to see the theory of relativity Ah, the origin of the universe and other things to take entertainment, to tell the truth this kind of pastime is the cheapest, the cost will not be higher than the otaku to appreciate the performance of the teacher's cost. After a careful reading of some of these masters ' writings, I found that time travel could theoretically, but in f

the seventh major philosophical proposition in history: Einstein's Light (Einstein's Beam)~ Einstein's famous special theory of relativity is a thought experiment that was set up at the age of 16. In his autobiography, Einstein recalled that he had dreamed of pursuing a light in the universe. He reasoned that if he was able to move around the light at the speed of light, he should be able to see the light as "an electromagnetic field that is constantl

song, and I was familiar with playing it on home TV. I stayed away from my home for the first time, even though I lived in my uncle's house.I didn't get an exam in the high school because I got two points. In fact, my sports score is 8 points. If I had a better sports score, I wouldn't do that. I began to feel the cold eyes of others.High School, I began to indulge in computer games again, so high school has been ruined for a year. Later, I was taught by my Aunt II to turn the evil spirits back

himself, he believes that the concept of computer science in 1960s is not suitable for describing physical systems due to the lack of concurrency. One important concept is that Petri net does not have the so-called "Global Time" concept, because it conflicts with the special theory of relativity. On the contrary, Petri Net can describe the time sequence of each node. From the perspective of special relativity
