What is difference between positive logic system negative logic system?
If you would like to perform an action by energising to act ( Logic 1 = desired output) then it's positive logic. If you would like to perform an action by de-energising to act ( Logic 0 = desired output) then it's negative logic. Here is an example for the positive and negative logic POSITIVE LOGIC NEGATIVE LOGIC o/p Y = 1 (energise to act) o/p Y = 0 (de-energise to act) A B Y A B Y 1 1 1 1 1 0 1 0 0 1 0 1 0 1 0 0 1 1 0 0 0 0 0 1 any how the required action can be performed by using either a positive logic or a negative logic.

Philosophy is the study of ideas like knowledge, truth, realities and the meaning of life. Philosophy helps individuals to gain understanding. Logic is a way of thinking a…nd reasoning about something to fully understand it. Logic is a way of analyzing facts or situations.
Fuzzification comprises the process of transforming crisp values into grades of membership for linguistic terms of fuzzy sets. The membership function is used to associate a g…rade to each linguistic term. Fuzzification is the process of changing a real scalar value into a fuzzy value. This is achieved with the different types of fuzzifiers. There are generally three types of fuzzifiers, which are used for the fuzzification process; they aresingleton fuzzifier,Gaussian fuzzifier, andtrapezoidal or triangular fuzzifier.
The Logical Data Model (LDM) is derived from the Conceptual Data Model (CDM). The CDM consists of the major entity sets and the relationship sets, and does not s…tate anything about the attributes of the entity sets. The LDM consists of the Entity Sets, their attributes, the Relationship sets, the cardinality, type of replationship, etc. The Physical Data Model (PDM) consists of the Entity Sets (Tables), their attributes (columns of tables), the Relationship sets (whose attributes are also mapped to columns of tables), along with the Datatype of the columns, the various integrity constraints, etc. Erwin calls the conversion / transformation of LDM => PDM as Forward Engineering which further leads to the actual code generation and the conversion of Code => PDM => LDM as Reverse Engineering! Though the question says specifically about Erwin, the above explanation is independent of the datamodeling tool used for the purpose.
Theorems, corollaries, and postulates.
A positive logic system will output true only when the input is true. A negative logic system will output true only when the input is false. The NOT logic gate is an example …of a negative logic system. That is, NOT( false ) will output true.
A theory is just a thought. Logic is when a theory has been put to the test and is proved to be correct.
First of all, I will attempt to explain what logic or "logical" means. I'm assuming that the reason you are looking this up is because you don't know the definition of logical… or practical. Perhaps, you don't know the definition to either of them. So, it makes sense to explain them both not just by definition but in a way that makes sense to everyone... well... hopefully. Things that make sense are logical. Data or information that is backed by factual evidence and that follow true reasoning are logical. If someone didn't know what "logical" meant then I would explain it by simply telling them that things happen for a reason. Things tick and are the way that they are for a certain reason. This "certain reasoning" or "fact" is logic or "logical." It would be logical for someone to think that if a person gets hit with a baseball they are going to feel it. Why is it logical? It is logical because 99.9% of humans feel pain. Unless you have some kind of medical reason as to why you don't feel pain, most people feel pain. So based on the fact that everybody feels pain, it is therefore "logical" that if you get hit by a baseball, you are going to feel it (and it's probably going to hurt). It wouldn't be logical to say that a person won't feel the baseball at all if it hit him/her in the leg traveling 90 miles per hour because every human (for the most part) feels pain. It is fact that all people feel pain therefore if you get hit by a baseball; you're going to feel it no matter what. Logical evidence is pretty much the same thing as factual evidence. Things that are backed by "facts" are also backed by "logic" until disproven. Another example of something logical is the fact that colors white and red make the color "pink" if mixed together. It wouldn't be a logical assumption to say that mixing white and red together create the color green. That wouldn't make any sense at all. So, basically logic is simply why everything ticks the way that it does proven by facts. Hopefully I explained what logical and logic mean to a way that you can understand it. Now I will attempt to explain what practical means. Practical is in the same ballpark as logic. They both intertwine each other, but there is a difference between them. I will use the baseball example again to try to explain "practical". Being practical to me is basically just having good judgment. As I said above that if you get hit by a baseball you are going to feel it no matter what because humans feel pain. This is only logical. Well, a practical stance would be to say that the baseball is going to hurt once a person gets hit by it. Practical and logical are very close in terms but practical involves more common sense while being logical involves cold hard facts. As I said above the logic involves facts, being practical just involves good judgment and common sense. By using "good judgment", a person can assume that if you get hit by a baseball traveling 90 miles per hour that it is most certainly going to inflict an ideal amount of pain. In other words, it's going to hurt quite a bit. A person may not have to go to the hospital afterwards, but they are definitely not going to just shrug it off in 2 seconds either (practical). It would be practical to assume that the person is going to have a bruise the next day in the area that they got hit with the baseball. As for the difference between logical and practical, I hope I explained it well. It is concluded that both logical and practical can both be linked together; there are logical sides to things just as there are practical sides to things and situations. Another good example of practical: Let's say that someone built a home designed to withstand a tornado. It would be practical to assume that a home of this magnitude should stay intact if hit by a tornado. It would also be good judgment to say that some form of the home had to be altered somehow by the tornado whether true or not. "It would also be good judgment to say that some form of the home had to be altered somehow by the tornado whether true or not." - This sentence is a perfect example that includes both logical and practical use. The practical side is the fact that a person is using good judgment stating that the home had to be altered some way because it is being hit by a tornado. The logical side of this statement would be whether this is true or not. Logic uses facts to support arguments, while a practical application uses common sense and good judgment to support arguments. A good philosophical individual uses a lot of practical application to support logical aspects. I would also like to include that it would not be a logical statement to say that someone is enduring excruciating pain after getting hit by a baseball. This would be a practical assumption, not a logical assumption. Why would this not be a logical assumption? It is not a logical assumption because there is a possibility that the person is not enduring an excruciating amount of pain. This is where practical and logical are different. Remember that logic has to be supported by 100% facts and practical is merely an incredibly good assumption or good judgment (usually, but not always common sense). As I stated above, logical and practical stances are used depending on the situation. They are both used in different situations and with different information. Depending on certain issues or mysteries that need to be solved, both logical and practical stances can be put to use. Sometimes a logical standpoint would simply not work in certain situations because certain information is unknown or certain facts are not obtained. Practical standpoints (on the flip side) are used when facts are unknown and/or certain information is uncertain. Practical uses calls for good judgment, great predictions, and using common sense. I'll give some examples of some situations below and you decide whether or not be practical or logical in order to figure the situation out. I'll have the answers posted below the questions, so don't scroll down until you have chosen the answers yourself. 1) Does my car need gas to run? (practical or logical answer?) 2) Why did that person just run out of that house wearing a black ski mask? 3) My best friends wedding is tomorrow. Do you think there is going to be a party afterwards? 1) Yes, all vehicles need gas for the most part. Logical 2) I don't know, if I had to guess I'd say he was trying to steal something or commit some type of crime. Practical 3) Considering that it is a wedding, there is usually some kind of party afterwards. Practical
psychology and logic both deal with thought and reasoning but logic deals with only the reasoning that distinguish between correct reasoning and incorrect reasoning.
Reasoning and logic are highly misunderstood concepts. Often, they are considered as synonyms. The only similarity between reasoning and logic is that they both are types …of thinking. Otherwise they are just the opposite. Reasoning can be defined as the mechanism, which converts an involuntary thought into a voluntary thought. Logic can be defined as the mechanism, which converts a voluntary thought into involuntary thought. Reasoning: 1. Reasoning deals with differences only. It ignores similarities. 2. It assumes that every cause has an effect and that every effect has just one cause. 3. Reasoning is voluntary and transient. Any thing eternal should be considered as logical. 4. Since reasoning deals with differences only and also enables us to be conscious of our entire knowledge it creates an impression that our knowledge has improved enormously. 5. It makes all activities of life independent of each other. Thus in reasonable life it is possible to correct just one activity without affecting any other. 6. Since it deals with differences only it enables us to solve just one problem at a time. 7. Reasoning is ideally suited for the material world. It is less suitable for body and least suited for mind. This, is because body and mind act as single units. Dividing the body is difficult and dividing the mind is impossible. Logic: 1. Logic deals with similarities. It ignores differences 2. Logic assumes that similar causes lead to similar effects. 3. Logic is involuntary and eternal. 4. Since logic considers similarities and also makes our knowledge involuntary it condenses knowledge, creating an illusion that our knowledge is reducing. 5. It merges all activities into a single giant activity called life. Thus in a logical life it is not possible to correct just one activity without affecting any other. 6. Since it deals with similarities logic enables us to rectify our entire life simultaneously. 7. Logic is ideally suited for body and mind because body and mind work as single entities. Logic ultimately leads us to the seven basic kinds of thinking and then to the mind selector, that selects one of the seven kinds of thinking. However, at this stage logic is totally involuntary and only a master of Original Meditation can be able to be aware of these. Reasoning and logic are two of the seven basic kinds of thinking. Natural thinking, the default thinking of human beings is a blend of reasoning and logic. ANS2: Reasoning is the general term for the process of arriving at an answer to a choice. Many specific processes can lead you to accepting a choice and logic is among those processes. Of the processes, logic and mathematics can produce universally accepted truth. Faith and trust in an authority can produce truth among those who share the same faith or who accept the same authority. The scientific method can also lead to a reasoned choice, however, science, by itself, will not produce truth since the senses are fallible and empiricism is the basis of science.
I would say logic is a prerequisite for science. In other words science is specific application of logic, not something completely separate. Logic presents the next stage in t…he scientific process or thinking. So every logical thing can only be logical if its approved by a scientific method; (theory, hypothesis, e.t.c). One leads to another.

There's nothing ethical about logic, logic is reason and rationality. It is my favorite out of the 3. Asking what is rationally reasonable, would be ethics, because then it's …about personal morals.

First of all, logic level needs to be defined. Lets start with zero. Zero is considered the ground state in most logic systems. Zero has value. In TTL based logic systems, a z…ero is a voltage beteen 0.0 and 0.8, and most drivers spec out to provide at most 0.4. That is zero. We call it logic low. Now lets define logic high. In TTL, high is anything higher that 2.0 volts, and it is typical to see 2.4 volts. That "no man's land" between 0.8 and 2.0 is off limits, and reserved for transistion voltages only. You might ask, why not +5 and ground? See CMOS for that one. This is a discussion of TTL. At some point in time, you decide what is true and what is false in your circuit. Most engineers would say high is true in low is false. That is fine As long as they are consistent, they are OK. Even if thay change between sections of a circuit, they are find, so long as they pay attention. So much for the long winded spin up. Here is the answer... If you have a gate that take two inputs and generates a high output when and only when both inputs are high, you have a positive logic AND gate. Your AND gate takes two inputs, and if they are both true, the output is true. Wonderful. Take that same gate and pretend the inputs are negative logic and what do you get, but an OR gate. The gate generates a low output when and only when either input is low. You have a negative logic OR gate. Your OR gate takes two inputs, and if one or both of them is true, the output is true. Wonderful. Beauty is in the eye of the beholder, eh? Why would you choose one over the other? It turns out that you might have an extra NAND gate or two and you want a NOR gate. Well, with a bit of careful design, one becomes the other. Another, specific case... In the Intel 8085 microprocessor, the ALE (Address Latch Enable) pin is positive logic; high true, low false. ALE initiates a sequence of operations known as a bus transaction where an address is emitted and then data is read or written. Along the way, two other pins RD- (Read inverted) and WR- (Write inverted) actually conduct the read or write transaction. RD- and WR- are negative logic, they are true when low and false when high.
