section{Introduction}label{INTR:sec}
In this paper we propose and solve polynomially in time and space a problem that consists on deciding whether, given an array called {em card} of $mathbf{n}$ columns and
$mathbf{m}$ lines and whose entries, denoted $ij$,
$2leq ileqmathbf{n}$ and $2leq jleqmathbf{m}$, contain a finite set of disjunction of two literals (chosen among a finite set of atoms), then all possible combinations, $mathbf{n}^{mathbf{m}}$, of conjunctions over unsatisfiable or no. Our interest is theoretical although simulations of parallel computation can be performed using cards introduce here. On showing that the decision process for a card can be performed polynomially, we built a new path to understand computational complexity questions and in future works, we will establish more bounds in complexity questions.
A precise definition of {em algorithm} was given by Alan Turing in
1937 (see cite{AT1937}). A natural question arises: {em What is the computational difficult to perform some algorithm?} See, in chronological order, cite{RMO1959}, cite{RMO1960}, cite{HS1965} and others.
Classification of complexity are find in cite{M87}. Our aims are to to open a way to deeply understand complexity questions on polynomially solving an apparently expsize problem.

Let the set of edges, $E$ be written as an ordered set,
${e_{1},dots,e_{k}}$.
As a first step, we load the set of edges $Search$ with $E$ and for all $1leq ileq k$, we work with $Search={e_{i},dots,e_{k}}$, if $e_{i}$ is compatible and complete, the search ends with an output

This section outlines and describes the various elements of the program logic model (see Figure 2). Our logic model is an important evaluative tool as it helps to explain the ideas behind the development of the DCD guidelines and the reasons why DCD programs will lead to positive outcomes in deceased organ donation.
In this paper I will evaluate and present A.M. Turing’s test for machine intelligence and describe how the test works. I will explain how the Turing test is a good way to answer if machines can think. I will also discuss Objection (4) the argument from Consciousness and Objection (6) Lady Lovelace’s Objection and how Turing responded to both of the objections. And lastly, I will give my opinion on about the Turing test and if the test is a good way to answer if a machine can think.
Watson and the Shark is oil painting by John Singleton Copley. This piece was made in 1778, as a depiction of a boy named Brook Watson attacking by shacks in Havana, Cuba, and his shipmates launching a valiant rescue effort. The piece’s present location is the National Gallery of Art in Washington, D.C. While this historical painting is a snapshot of a real-life event, Copley uses low value hues and spotlight effect on Watson as well as his shipmates, giving us equal or more attention to the people saving Watson. Moreover, Copley challenges the conventional history paintings by giving all the saviors on the boat the same attention, and each one is allowed to have his individual role in the rescuing process.
Throughout history, society has pushed the envelope with civil liberties and civil rights by tackling Supreme Court decisions. From the decision to incorporate the Bill of Rights- i.e the Bill of Liberties- to the need to eradicate the disparity of African Americans and women, America’s citizens have fought for equality since the birth of the United States.
Artificial Intelligence (AI) is one of the newest fields in Science and Engineering. Work started in earnest soon after World War II, and the name itself was coined in 1956 by John McCarthy. Artificial Intelligence is an art of creating machines that perform functions that require intelligence when performed by people [Kurzweil, 1990]. It encompasses a huge variety of subfields, ranging from general (learning and perception) to the specific, such as playing chess, proving mathematical theorems, writing poetry, driving a car on the crowded street, and diagnosing diseases. Artificial Intelligence is relevant to any intellectual task; it is truly a Universal field. In future, intelligent machines will replace or enhance human’s capabilities in
When I scheduled my classes last winter, I knew I had to fulfill my requirements for general education and take English Composition II. I had heard from my oldest daughter that Comp II was no fun at all and when she took it, she was bored to tears. Not knowing any better, I took her word and prepared myself for a rather boring and uneventful semester of “robot writing”. The kind of writing that was dull and made one’s eyes cross from boredom. I soon found out that this didn’t have to be the case. Academic writing and research could be enjoyable and it was not at all boring.
Seemingly insignificant, symbols are often utilized by an author to create another form of dimension within a story. According to German philosopher and poet, Friedrich Nietzsche, “words are but symbols for the relations of things to one another and to us; nowhere do they touch upon absolute truth.” Khaled Hosseini’s The Kite Runner, Hassan’s cleft lip, kites and the sacrificial lamb are symbols that show a deeper sense of character development throughout the novel.
When witnessing strangers meeting for the first time, it becomes quickly obvious that these individuals are uncomfortable with each other, and begin to go through processes to ease this discomfort. This process is attributed to the Uncertainty Reduction Theory, which states that uncertainty is a negative experience that requires elimination in order for relationships to continue and grow (Theiss & Solomon). The reason why there is such a fight against uncertainty is because of the emotional toll that it takes upon individuals. Uncertainty has been linked to negative emotions, including anxiety, and can cause difficulty in the adaptation to new environments and events (Gilbert, 2005). It can be therefore assumed that completely eradicating

Looking at the world where we live everything in someway is connected. Our world is not simple and in fact consists of multiple complex systems. Some everyday examples of complex systems are the brain, immune system, insect colonies, and even social networks such as Facebook and twitter. So what exactly do all these have in common in order to be a complex system? First is the fact that each one has a large amount of simple components that work together by communication through signals without being under leadership. But not all systems are exactly the same so we can break it down further into chaotic systems, complex adaptive systems, and nonlinear systems. Chaotic systems differ in that they are non-linear and are sensitive to initial conditions. Therefore any uncertainty in the system will not produce an outcome that can be predicted later on. A good example of a chaotic system would be the stock market because the prediction of its outcome is unknown due to its sensitivity to initial conditions. Complex adaptive systems are just like they sound. They are capable of adapting to the environment such as the immune system. It’s white blood cells work together to recognize foreign bodies and create antibodies for future encounters.
Von Neumann architecture, or the Von Neumann model, stems from a 1945 computer architecture description by the physicist, mathematician, and polymath John von Neumann and others. This describes a design architecture for an electronic digital computer with a control unit containing an instruction register and program counter , external mass storage, subdivisions of a processing unit consisting of arithmetic logic unit and processor registers, a memory to store both data and commands, also an input and output mechanisms. The meaning of the term has grown to mean a stored-program computer in which a command fetch and a data operation cannot occur at the same time because they share a common bus. This is commonly referred to as the Von Neumann bottleneck and often limits the performance of a system.
Pascal programming language was designed in 1968, and published in 1970. It is a small and efficient language intended to encourage good programming practices using structured programming and data structuring. Pascal was developed by Niklaus Wirth. The language was named in honor of the French mathematician and philosopher Blaise Pascal. In 1641, Pascal created the first arithmetical machine. Some say it was the first computer. Wirth improved the instrument eight years later. In 1650, Pascal left geometry and physics, and started his focus towards religious studies. A generation of students used Pascal as an introduction language in undergraduate courses. Types of Pascal have also frequently been used for everything from research projects to PC games. Niklaus Wirth reports that a first attempt to merge it in Fortran in 1969 was unsuccessful because of Fortran's lack of complex data structures. The second attempt was developed in the Pascal language itself and was operational by mid-1970. A generation of students used Pascal as an introductory language in undergraduate courses. Pascal, in its original form, is a Procedural language and includes the traditional like control structures with reserved words such as IF, THEN, ELSE, WHILE, FOR, and so on. However, Pascal has many data structuring and other ideas which were not included in the original, like type definitions, records, pointers, enumerations, and sets. The earliest computers were programmed in machine code. This type of programming is time consuming and error prone, as well as very difficult to change and understand. Programming is a time-consuming a process. More advanced languages were developed to resolve this problem. High level languages include a set of instruction...
First of all I had no much computer programming skill from the past , but I do have some short-term programming courses completion. of course the basic idea from the past about python language programming is a big deal to me to prepared myself early for this class. Otherwise not easy to find out exactly what is going on around computer language program; programming a computer is not so simple and controlled within a short period of time, computer programming is need big time and a lot of effort.
Scheduling algorithms say how much time is allocated to Processes and Threads. Their goal is to fulfil a number of criteria:
