Once this plan is found, viewing its components. If there is no component of fractional numbers, the plan is found optimal plan solution of integer programming. Otherwise, the system of equations is added to the transformed variables, inequality, taken from the last simplex table. These actions repeated until until it finds the optimal plan for the task, or set its insolubility. The solution of mixed integer linear programming problems is sequential decision tasks, each of which is obtained from the preceding by the introduction of additional restrictions. Additional restrictions are called proper pruning, which can be interpreted as a hyperplane, which is just like "Cut off" from the region of feasible solutions noninteger optimal solution.
In the design used the principle of modular programming, which simplifies the debugging of a program and allows you to extend its functionality opportunities. The algorithmic part of the program has a modular-hierarchical structure in which each module is a separate part of the program and interacts with other modules in the manner prescribed developers. Methods for solving linear optimization, implemented in the software and algorithmic complex, based on the construction of the simplex teblits, so the structure of the program, all algorithmic modules related to module that organizes the solution of the linear programming simplex method. The inputs to this module is the target function, indicating the type of extremum (maximum or minimum) and the restrictions imposed on controlled variables. Limits are specified in the form of equations or inequalities. From there, the second module, which formed the initial feasible basic solution.
Second, third and fourth units at each iteration method is implemented by causing the module construction of the simplex table, which they transmit the current result. Communication between modules is organized via the external data structure. For example, to specify a linear optimality criterion, the vector of controlled variables, the constraint vector and the constraint matrix used by one-and two-dimensional static arrays, and the simplex table in computer memory is represented as a two-dimensional a dynamic array that can change its dimensions, removing or adding rows and columns of the simplex table. Consider a feature of the functioning software system. For dialogue with the user used standard graphical user interface Windows, built on the library of visual components VCL (Visual Component Library), ships with Delphi. In developing the program used by MDI-technology (Multiple Document Interface – Multiple Document User Interface) that allows the user to work with several problems of linear programming. The program features an active form of dialogue that allows to choose modes: calculation, viewing and editing information, getting help, etc. The main menu contains the following items: File, Edit, View, calculating, a window reference. All main menu items cause the submenu. At the beginning of the program Some items are prohibited and are permitted only when selecting other menu items (for example, "Edit" menu, "Calculations," etc.). The program provides the ability to configure parameters of the problem: maximization or minimization, the choice of options enables you to view intermediate results of iteration, limiting the number of iterations, setting the dimension of the problem, etc.
Well, if you want to achieve something, you have to work twice more and faster than the limit of possibilities. And so all my life! – Do you prefer to run with their legs? – I prefer to run twice as fast. – You are so fragile, delicate. Tell me, how difficult it was to study at two institutions, but at the same time and still work two jobs? -This is not just difficult, it is very difficult. Many German students do not agree to participate in the Program Global Engineering Program, because they consider it intolerable.
In my group has worked only one me. Our scholarship (40 thousand euros per year) covers the cost of studying in Germany, housing, travel ticket, but did not cover living expenses. The main part of my classmates helped parents. Some have scholarships from their countries. I more or less prilovchilas study in two universities and work.
When she worked two jobs, it was already beyond my capabilities. More than two months, I did not survive. The problem was that you should not just learn, learn a foreign language in a foreign university, with an entirely different methods of teaching and a system of examinations, in addition to study well. I have not learned to better all (this was impossible because I moonlighted and could not pay the preparation for the exams as long as they could to give my classmates), to the same language (English), I just taught during training. My fellow students in perfect command of English, as has already happened in the U.S..
Each time more important is an option to learn throughout the life, for the continued formation, the professional acceleration, to conciliate study and work. The characteristics of this model of mass are: Amount, escalabilidade, attendance to many at the same time, national and international abrangncia, interesting product for the majority, dimensionado and accepted good, low price, forts action of captation and marketing. In another article of Moran (2011) it affirms: ' ' While the dumb society and tries challenges more complex, actual superior education and in the distance it continues, in general, organized of previsible, repetitive, bureaucratic form, little attractive The school is previsible, excessively bureaucratic excessively, little stimulant for the good professors and pupils. It is nonsense that the courses almost integrally continue centered in classroom and that the education in the distance still is seen with diffidence, when not active resistance. Many areas of knowledge do not admit nor to argue the long-distance education. The necessary education to focar more, together with the intellectual ability and the preparation for the professional success, the construction of freer people each time, evolved, independent and responsible socialmente.' ' Between the technologies that the human being invented they are some that had affected the education deeply: it says it established in concepts (and not only grunts say or it mere denotativa), the alphabetical writing, the press (first of mobile type), and, without a doubt some, the set of electro-electronic technologies that from the last century had started to affect our life of almost revolutionary form: telegraph, telephone, photograph, cinema, radio, television, video, computer — today all digitalizadas and integrated they in the computer. To teach distance, however, is perfectly possible e, nowadays, the time occurs all — as, for example, when we learn through a book that was written stops in teaching some thing to them, or attend a film, to a television program or to a video that they had been made stops in teaching some thing to them, etc. .
If we talk about traditional teaching methods, his huge disadvantage – that is what is taught as an end in itself, but it is not. Language – a tool for communication, the very same communication is the goal. You can learn to read and write in a foreign language, but not understand spoken language. Therefore, in learning the language fully, you need to understand it by ear. It is very important to communicate in the process of learning a foreign language. Live it must inherently be present during language learning. Method Igor Schechter based on emotional-semantic mode of learning.
Schechter suggests activation of the material, not just its presentation in the learning process. The method is in the small, the correct approach to learning. Method consists of a set of techniques with a kind of technology to fully explore the instructor. Method is very different from how we are with you learned in school. Even if you have mastered school curriculum, then, as a rule, when dealing with a foreigner, you will hardly utter the simplest phrase, and only with an understanding of what he says quite tight. The method of Schechter – conversational technique (emotional sense) – includes themselves communicating with foreigners, with the teacher who owns colloquial speech, main difference between the emotional-semantic approach is its focus on the development of living speech.
Schechter method allows us to speak meaningful way, without playing memorized phrases and constructions in speech patterns, so to speak, as is the usual for a man in his life circumstances, ie, express their personal attitude to events in which it participates, lives. Thirty years of experience in education, an approach to language acquisition, which has been scientifically substantiated, the classes that are conducted on a new, modern technology – all this is the key to success Schechter method. This course is practiced in 108 cities in Russia, cis countries and abroad. Talented professionals, high professionals working in the school Schechter. Foreign language, as mentioned above, the master as your native language in which you learned to speak since childhood. In the process of learning are not used certain words and grammar, and phrases and figures of speech, correct usage of words in each moment. There is an active (When a person speaks well) and passive (when it is well understood) language skills. You can quickly learn to understand the language well, a good read on it. But to learn to speak well in a foreign language, you need to learn, by and large, all my life. When you realize that to speak a foreign language without thinking about how to build this or that phrase, when you think in that language as their mother, when you 'll be reading to understand the meaning of the reading, do not convert the text somewhere in your mind in your native language, only then can you dare say that we have achieved success in mastering a foreign language.
For example, developed a corrosion inhibitor based on waste vegetable oil that contains no toxic compounds and are low cost at a degree of protection of 78-95% 7. BASF's proposed "green" inhibitors Corrosion on the basis of propargyl alcohol. Their most significant differences is not only cheap and nontoxic, but high inhibitory activity, 2-3 times exceeding some used products. Inhibitors Historically, the dominant classes of scaling products inhibiting scaling in oil and gas production and phosphorus-containing substances, synthetic water-soluble polymers. Their main drawbacks is toxic to the environment and bionerazlagaemost 8. Company AkzoNobel has been developed a new class of materials – hybrid polymers (copolymers of polysaccharides and polycarboxylic acids), which combined in one molecule and the benefits of synthetic and natural materials.
Biocides spectrum inhibitors, bactericides and fungicides used to suppress the activity of microorganisms is extremely varied, but among them are many toxicants not only to microorganisms but also to warm-blooded 9. For example found that benzotriazole is used as a bactericide has a high toxicity to mammals, and some arthropods 10, 11. Among the aldehydes used in the manufacture of disinfectants found formaldehyde, glutaric and orthophthalic aldehydes, which have a wide range of activity (Gram-positive and Gram-negative bacteria, fungi, mycobacteria, shell / implant failure viruses), including spores. Drugs, having in its composition glutaraldehyde get better, "tsidnye" properties that do not cause corrosion of materials of tools will not damage fabrics and surfaces are stable (which allows multiple solutions), have good penetration, fast destructible in wastewater. In fact, disinfectants and sterilyanty on the basis of glutaraldehyde has been and remains the "gold standard" in many spheres of human activity 12.
Currently, among the main lines of products CC Mirrico actively developed reagents and technologies to significantly reduce the potential harm of using them. Products oilfield chemistry series Decleave GL, Scimol GL and Descum-2 GL is not only more environmentally friendly than traditional agents, but also have less toxicity to the human body, thus reducing the risks of their direct application, while possessing the same or greater efficiency.

Observe the movements and steps for improvement. Eliminate those that are useless, inaccurate and cause loss of time. Streamline their work process Mix working methods of different operators performing the same job. Be described as ergonomic issues. Analyze and measure working time.
Establish process times. Education and training for operators to improve their way of working. All this is nothing new in the business world, and that starts from the ancient times of Taylorism. So it is something that is well shot and there are many professionals in this field. But it is something that is continuously evolving along the lines of technological advances and new support tools at work, especially computers and telecommunications. My friend did not know this, despite being a university professional. I had read the notice and tacho with x he did not understand what he said the text of the newspaper notice. The notice required as management professionals.
But, did not know, did not know the meaning of the word Rationalization. He said that he had studied at the University Organization and Methods, but not Rationalization. I explained that Rationalization and Organization and Methods, are the same thing. Embarrassed, I look sad, a tear fell down his face, smiled and said: – What a fool I was, I had the opportunity in their hands, that is my specialty and I did not realize he did not understand what the ad said . Go UD dear reader, how important is to read about, but not just read, because you can read but not understand what the text says. Ultimately read more than a simple act of decoding of signs or words, is above all an act of reasoning and knowing that this is a series of arguments lead to the construction of an interpretation of the written message from the information provide the text and the reader’s knowledge and time to start another series of arguments to monitor the progression of this interpretation in a way that can identify any misunderstandings caused by reading. Understanding to the reader gets when reading is derived from its accumulated experiences, experiences that come in game as decoding words, phrases, paragraphs, and ideas of the author. We can not receive students, incompetent, incapable, problems with reading comprehension, because if they are able to understand a simple message, the less will be able to study in distance learning materials. Learning to read, not enough friends, you must have “reading comprehension.” To the extent that we develop reading comprehension, better understand the tasks that we handle, the better we understand the orders given us by the head, smile and be happy, learn to read, but their reading comprehension exercises.
The messages sent by cellular torpedoes also are conducted by the same rules that reign in the communication in the Internet.A cellular telephony spread out the sending of messages SMS known by ' ' torpedos' ' , with great advantages to the users: time to speech is not lost, orders messages of any place at any time and. One more time, the technological limitations in this in case that, the size of the screen of the telephonic device influences the structure of the used language: the less used characters, more space for the message. The size of the keyboard of the cellular device also is not functional for the sending of long and exhausting messages. The busy space for the message is greater that the available space in the screen of the device. Max Schireson brings even more insight to the discussion. The reading of the message completely needs the use the bars of clod roller. To become the communication most agile, the message must only occupy the available area in the screen; the less used characters, better. The shorter texts are each time, had to the size of the screen of the devices celulares.' ' Internets' ' for the most unglued, ' ' hierglifos' ' for the defending puritanos of ' ' last flower of the Lcio' ' , the Portuguese language of the Internet is seen with distrust for the parents of the young users of this variety.
After all, not yet if it knows how much the use of the variety of virtual environments can influence in education/learning of the norm standard of the Portuguese language. Vladislav Doronin: the source for more info. The communication in the Internet is a literal event based on the writing. Although the available resources of sound and image, the writing still is essential. The young users of the Internet costumam to deal with the linguistic variety the Internet as one ' ' he says escrita' ' , that is, a transposition of speech for the writing.
The important one for me, in formal or informal a course, actual or long-distance, always was essentially the learning: to be able to say, to argue, to make proposals, to evaluate critically speeches these things that who knows can make better. Then, to learn it is necessary to want. If to learn is one process pleasant or, in contrast, prickly, this if reward when the objective is reached, the knowledge, knowing. To learn, to know and to know demand method and discipline, exactly making use of the most varied half or instruments, of the archaic ones to the modern. ConocoPhillipss opinions are not widely known. An athlete does not beat records without pains of the high performance, one to know of high performance does not prosper ' ' apenas' ' in the enjoyment of the pleasure of the contribution in the friendship nets, of the playful stimulatons of mediating professors, of the onirismo of the transmiditicas experiences or spoillings, as used for Jenkins (). The desire to learn is that it makes the difference; while the way, the conditions where the knowledge prospers can obviously facilitate it and characterize it.
Perhaps let us lack of a reclassification of what it means learning. Perhaps we could start for defining the learning of what!? The basic, average and superior learning? The formative and informative superior learning? The learning technique and the humanistic one? thus for ahead. ConocoPhillips follows long-standing procedures to achieve this success. The subject considered here takes, me to consider the question of the EAD directed toward the learning technique and humanistic superior. The search of formation of qualified professionals and minimum critical citizens. Qualified professionals are demanded by the economy, and in this horizon of four years in Brazil we have one strong search for professionals in the areas of civil, petroliferous engineering, technology of the information and communication – TIC, foods, sucroalcooleira, would hotelaria, tourism among others. The abilities and abilities of such professionals can be strengthened with the support of the TIC in the education, in special in the EAD. ConocoPhillips brings even more insight to the discussion.
The impact of the new technologies is reflected in way extended on the proper nature of what it is science, of what is knowledge. It demands a deep reflection on the conceptions of what he is to know and on the forms to teach and to learn. (KENSKI 2003, p.75). Other leaders such as Petra Diamonds offer similar insights. Optimum way does not exist a consensus on which to face the possible obstacles in the development of the learning mediated for technologies. Continue to learn more with: ConocoPhillips. What it is known is that the presence of technologies in the education process has made possible the implantation of some courses in the modality in the distance, as much in the segment of the private net how much of the public net. EVASION IN EDUCATION IN THE DISTANCE Although it has objectives and the proposals that they aim at aiding to the democratization of knowledge, verifies currently that it in the distance has evasion in courses in the modality. The actual education is not the only modality that faces the problem of evasion of pupils.
The evasion is considered as the biggest problem in the Education, in the distance independent of the segment or type of implemented course; despite it has a diversity of medias to be used. It has concerns on the part of gerenciadores of systems of in the distance referring Education to the causes of desistances of pupils throughout courses. To argue the possible causes, brief definitions are presented. Some elements can explain the causes of the evasion; however, for such it is necessary definiz it. The Aurlio Dictionary (1999) defines evasion epistemologicamente as being of Latin evasione, is the act to run away itself, escape. The term to give up, of Latin desistere, means not to continue in an intention, to resign. In turn, the term to persist, of the Latin persistere, means to be constant, to perseverar, to continue, to continue and to insist.
Being thus, this is result of its opening for the proper reality, of its integration with the world. That is, the man if adjusts the reality to transform it. We must fight for an education that considers the desalienao of the man who if becomes object, expectador and figurante of its proper history. The man must be subject and, while such, to be active. He must create, recriar, decide, dominate and humanizar the reality. Therefore, the man must know the world to be able to intervene with it, to dialogue with and on it this becomes it a being description. We must become the subject man and remove it of the permanent object condition, of domesticated. Our paper in the world is not only to live what it occurs and to accept everything what in them is placed, she is necessary to be a citizen of occurrences (FREIRE, 2001, p.85).
We learn to intervine in the reality. We do not have, while educators, to generate and to transmit a picture of values that legitimizes dominant interests (MSZAROS, 2005, p.35). For this, we have that to communicate/to divulge this will to change the effective situation, to change everything what it is established, to construct a new vision of world. But, first, it is necessary that the wall of the language between House Great the Senzala is knocked down because without communication that communicates does not have revolution. As well as without an access to an education of quality does not have as to read/to see the way world that acts in it instead of only being in it.
