  • 81 Henson, William Samuel

    SUBJECT AREA: Aerospace
    [br]
    b. 3 May 1812 Nottingham, England
    d. 22 March 1888 New Jersey, USA
    [br]
    English (naturalized American) inventor who patented a design for an "aerial steam carriage" and combined with John Stringfellow to build model aeroplanes.
    [br]
    William Henson worked in the lacemaking industry and in his spare time invented many mechanical devices, from a breech-loading cannon to an ice-machine. It could be claimed that he invented the airliner, for in 1842 he prepared a patent (granted in 1843) for an "aerial steam carriage". The patent application was not just a vague outline, but contained detailed drawings of a large monoplane with an enclosed fuselage to accommodate the passengers and crew. It was to be powered by a steam engine driving two pusher propellers aft of the wing. Henson had followed the lead give by Sir George Cayley in his basic layout, but produced a very much more advanced structural design with cambered wings strengthened by streamlined bracing wires: the intended wing-span was 150 ft (46 m). Henson probably discussed the design of the steam engine and boiler with his friend John Stringfellow (who was also in the lacemaking industry). Stringfellow joined Henson and others to found the Aerial Transit Company, which was set up to raise the finance needed to build Henson's machine. A great publicity campaign was mounted with artists' impressions of the "aerial steam carriage" flying over London, India and even the pyramids. Passenger-carrying services to India and China were proposed, but the whole project was far too optimistic to attract support from financiers and the scheme foundered. Henson and Stringfellow drew up an agreement in December 1843 to construct models which would prove the feasibility of an "aerial machine". For the next five years they pursued this aim, with no real success. In 1848 Henson and his wife emigrated to the United States to further his career in textiles. He became an American citizen and died there at the age of 75.

  • 82 Wolf, Carl

    [br]
    b. 23 December 1838 Zwickau, Saxony, Germany
    d. 30 January 1915 Zwickau, Saxony, Germany
    [br]
    German inventor of the most popular petroleum spirit safety lamp for use in mines.
    [br]
    From an old mining family in the Saxon coalfields, Wolf was aware from his youth of the urgent demand for a miner's lamp which would provide adequate light but not provoke firedamp explosions. While working as an engineer in Zwickau, Wolf spent his spare time conducting experiments for such a lamp. The basic concept of his invention was the principle that dangerous concentrations of methane and air would not explode within a small pipe; this had been established almost seventy years earlier by the English chemist Humphrey Davy. By combining and developing certain devices designed by earlier inventors, in 1883 Wolf produced a prototype with a glass cylinder, a primer fixed inside the lamp and a magnetic lock. Until the successful application of electric light, Wolfs invention was the safest and most popular mining safety lamp. Many earlier inventions had failed to address all the problems of lighting for mines; Davy's lamp, for example, would too quickly become sooty and hot. As Wolfs lamp burned petroleum spirit, at first it was mistrusted outside Saxony, but it successfully passed the safety tests in all the leading coal-producing countries at that time. As well as casting a safe, constant light, the appearance of the cap flame could indicate the concentration of fire-damp in the air, thus providing an additional safety measure. Wolfs first patent was soon followed by many others in several countries, and underwent many developments. In 1884 Heinrich Friemann, a merchant from Eisleben, invested capital in the new company of Friemann and Wolf, which became the leading producer of miners' safety lamps. By 1914 they had manufactured over one million lamps, and the company had branches in major mining districts worldwide.

  • 85 Artificial Intelligence

       In my opinion, none of [these programs] does even remote justice to the complexity of human mental processes. Unlike men, "artificially intelligent" programs tend to be single minded, undistractable, and unemotional. (Neisser, 1967, p. 9)
       Future progress in [artificial intelligence] will depend on the development of both practical and theoretical knowledge.... As regards theoretical knowledge, some have sought a unified theory of artificial intelligence. My view is that artificial intelligence is (or soon will be) an engineering discipline since its primary goal is to build things. (Nilsson, 1971, pp. vii-viii)
       Most workers in AI [artificial intelligence] research and in related fields confess to a pronounced feeling of disappointment in what has been achieved in the last 25 years. Workers entered the field around 1950, and even around 1960, with high hopes that are very far from being realized in 1972. In no part of the field have the discoveries made so far produced the major impact that was then promised.... In the meantime, claims and predictions regarding the potential results of AI research had been publicized which went even farther than the expectations of the majority of workers in the field, whose embarrassments have been added to by the lamentable failure of such inflated predictions....
       When able and respected scientists write in letters to the present author that AI, the major goal of computing science, represents "another step in the general process of evolution"; that possibilities in the 1980s include an all-purpose intelligence on a human-scale knowledge base; that awe-inspiring possibilities suggest themselves based on machine intelligence exceeding human intelligence by the year 2000 [one has the right to be skeptical]. (Lighthill, 1972, p. 17)
       4) Just as Astronomy Succeeded Astrology, the Discovery of Intellectual Processes in Machines Should Lead to a Science, Eventually
       Just as astronomy succeeded astrology, following Kepler's discovery of planetary regularities, the discoveries of these many principles in empirical explorations on intellectual processes in machines should lead to a science, eventually. (Minsky & Papert, 1973, p. 11)
       Many problems arise in experiments on machine intelligence because things obvious to any person are not represented in any program. One can pull with a string, but one cannot push with one.... Simple facts like these caused serious problems when Charniak attempted to extend Bobrow's "Student" program to more realistic applications, and they have not been faced up to until now. (Minsky & Papert, 1973, p. 77)
       What do we mean by [a symbolic] "description"? We do not mean to suggest that our descriptions must be made of strings of ordinary language words (although they might be). The simplest kind of description is a structure in which some features of a situation are represented by single ("primitive") symbols, and relations between those features are represented by other symbols-or by other features of the way the description is put together. (Minsky & Papert, 1973, p. 11)
       [AI is] the use of computer programs and programming techniques to cast light on the principles of intelligence in general and human thought in particular. (Boden, 1977, p. 5)
       The word you look for and hardly ever see in the early AI literature is the word knowledge. They didn't believe you have to know anything, you could always rework it all.... In fact 1967 is the turning point in my mind when there was enough feeling that the old ideas of general principles had to go.... I came up with an argument for what I called the primacy of expertise, and at the time I called the other guys the generalists. (Moses, quoted in McCorduck, 1979, pp. 228-229)
       9) Artificial Intelligence Is Psychology in a Particularly Pure and Abstract Form
       The basic idea of cognitive science is that intelligent beings are semantic engines-in other words, automatic formal systems with interpretations under which they consistently make sense. We can now see why this includes psychology and artificial intelligence on a more or less equal footing: people and intelligent computers (if and when there are any) turn out to be merely different manifestations of the same underlying phenomenon. Moreover, with universal hardware, any semantic engine can in principle be formally imitated by a computer if only the right program can be found. And that will guarantee semantic imitation as well, since (given the appropriate formal behavior) the semantics is "taking care of itself" anyway. Thus we also see why, from this perspective, artificial intelligence can be regarded as psychology in a particularly pure and abstract form. The same fundamental structures are under investigation, but in AI, all the relevant parameters are under direct experimental control (in the programming), without any messy physiology or ethics to get in the way. (Haugeland, 1981b, p. 31)
       There are many different kinds of reasoning one might imagine:
        Formal reasoning involves the syntactic manipulation of data structures to deduce new ones following prespecified rules of inference. Mathematical logic is the archetypical formal representation. Procedural reasoning uses simulation to answer questions and solve problems. When we use a program to answer What is the sum of 3 and 4? it uses, or "runs," a procedural model of arithmetic. Reasoning by analogy seems to be a very natural mode of thought for humans but, so far, difficult to accomplish in AI programs. The idea is that when you ask the question Can robins fly? the system might reason that "robins are like sparrows, and I know that sparrows can fly, so robins probably can fly."
        Generalization and abstraction are also natural reasoning process for humans that are difficult to pin down well enough to implement in a program. If one knows that Robins have wings, that Sparrows have wings, and that Blue jays have wings, eventually one will believe that All birds have wings. This capability may be at the core of most human learning, but it has not yet become a useful technique in AI.... Meta- level reasoning is demonstrated by the way one answers the question What is Paul Newman's telephone number? You might reason that "if I knew Paul Newman's number, I would know that I knew it, because it is a notable fact." This involves using "knowledge about what you know," in particular, about the extent of your knowledge and about the importance of certain facts. Recent research in psychology and AI indicates that meta-level reasoning may play a central role in human cognitive processing. (Barr & Feigenbaum, 1981, pp. 146-147)
       Suffice it to say that programs already exist that can do things-or, at the very least, appear to be beginning to do things-which ill-informed critics have asserted a priori to be impossible. Examples include: perceiving in a holistic as opposed to an atomistic way; using language creatively; translating sensibly from one language to another by way of a language-neutral semantic representation; planning acts in a broad and sketchy fashion, the details being decided only in execution; distinguishing between different species of emotional reaction according to the psychological context of the subject. (Boden, 1981, p. 33)
       Can the synthesis of Man and Machine ever be stable, or will the purely organic component become such a hindrance that it has to be discarded? If this eventually happens-and I have... good reasons for thinking that it must-we have nothing to regret and certainly nothing to fear. (Clarke, 1984, p. 243)
       The thesis of GOFAI... is not that the processes underlying intelligence can be described symbolically... but that they are symbolic. (Haugeland, 1985, p. 113)
        14) Artificial Intelligence Provides a Useful Approach to Psychological and Psychiatric Theory Formation
       It is all very well formulating psychological and psychiatric theories verbally but, when using natural language (even technical jargon), it is difficult to recognise when a theory is complete; oversights are all too easily made, gaps too readily left. This is a point which is generally recognised to be true and it is for precisely this reason that the behavioural sciences attempt to follow the natural sciences in using "classical" mathematics as a more rigorous descriptive language. However, it is an unfortunate fact that, with a few notable exceptions, there has been a marked lack of success in this application. It is my belief that a different approach-a different mathematics-is needed, and that AI provides just this approach. (Hand, quoted in Hand, 1985, pp. 6-7)
       We might distinguish among four kinds of AI.
       Research of this kind involves building and programming computers to perform tasks which, to paraphrase Marvin Minsky, would require intelligence if they were done by us. Researchers in nonpsychological AI make no claims whatsoever about the psychological realism of their programs or the devices they build, that is, about whether or not computers perform tasks as humans do.
       Research here is guided by the view that the computer is a useful tool in the study of mind. In particular, we can write computer programs or build devices that simulate alleged psychological processes in humans and then test our predictions about how the alleged processes work. We can weave these programs and devices together with other programs and devices that simulate different alleged mental processes and thereby test the degree to which the AI system as a whole simulates human mentality. According to weak psychological AI, working with computer models is a way of refining and testing hypotheses about processes that are allegedly realized in human minds.
    ... According to this view, our minds are computers and therefore can be duplicated by other computers. Sherry Turkle writes that the "real ambition is of mythic proportions, making a general purpose intelligence, a mind." (Turkle, 1984, p. 240) The authors of a major text announce that "the ultimate goal of AI research is to build a person or, more humbly, an animal." (Charniak & McDermott, 1985, p. 7)
       Research in this field, like strong psychological AI, takes seriously the functionalist view that mentality can be realized in many different types of physical devices. Suprapsychological AI, however, accuses strong psychological AI of being chauvinisticof being only interested in human intelligence! Suprapsychological AI claims to be interested in all the conceivable ways intelligence can be realized. (Flanagan, 1991, pp. 241-242)
        16) Determination of Relevance of Rules in Particular Contexts
       Even if the [rules] were stored in a context-free form the computer still couldn't use them. To do that the computer requires rules enabling it to draw on just those [ rules] which are relevant in each particular context. Determination of relevance will have to be based on further facts and rules, but the question will again arise as to which facts and rules are relevant for making each particular determination. One could always invoke further facts and rules to answer this question, but of course these must be only the relevant ones. And so it goes. It seems that AI workers will never be able to get started here unless they can settle the problem of relevance beforehand by cataloguing types of context and listing just those facts which are relevant in each. (Dreyfus & Dreyfus, 1986, p. 80)
       Perhaps the single most important idea to artificial intelligence is that there is no fundamental difference between form and content, that meaning can be captured in a set of symbols such as a semantic net. (G. Johnson, 1986, p. 250)
        18) The Assumption That the Mind Is a Formal System
       Artificial intelligence is based on the assumption that the mind can be described as some kind of formal system manipulating symbols that stand for things in the world. Thus it doesn't matter what the brain is made of, or what it uses for tokens in the great game of thinking. Using an equivalent set of tokens and rules, we can do thinking with a digital computer, just as we can play chess using cups, salt and pepper shakers, knives, forks, and spoons. Using the right software, one system (the mind) can be mapped into the other (the computer). (G. Johnson, 1986, p. 250)
        19) A Statement of the Primary and Secondary Purposes of Artificial Intelligence
       The primary goal of Artificial Intelligence is to make machines smarter.
       The secondary goals of Artificial Intelligence are to understand what intelligence is (the Nobel laureate purpose) and to make machines more useful (the entrepreneurial purpose). (Winston, 1987, p. 1)
       The theoretical ideas of older branches of engineering are captured in the language of mathematics. We contend that mathematical logic provides the basis for theory in AI. Although many computer scientists already count logic as fundamental to computer science in general, we put forward an even stronger form of the logic-is-important argument....
       AI deals mainly with the problem of representing and using declarative (as opposed to procedural) knowledge. Declarative knowledge is the kind that is expressed as sentences, and AI needs a language in which to state these sentences. Because the languages in which this knowledge usually is originally captured (natural languages such as English) are not suitable for computer representations, some other language with the appropriate properties must be used. It turns out, we think, that the appropriate properties include at least those that have been uppermost in the minds of logicians in their development of logical languages such as the predicate calculus. Thus, we think that any language for expressing knowledge in AI systems must be at least as expressive as the first-order predicate calculus. (Genesereth & Nilsson, 1987, p. viii)
        21) Perceptual Structures Can Be Represented as Lists of Elementary Propositions
       In artificial intelligence studies, perceptual structures are represented as assemblages of description lists, the elementary components of which are propositions asserting that certain relations hold among elements. (Chase & Simon, 1988, p. 490)
       Artificial intelligence (AI) is sometimes defined as the study of how to build and/or program computers to enable them to do the sorts of things that minds can do. Some of these things are commonly regarded as requiring intelligence: offering a medical diagnosis and/or prescription, giving legal or scientific advice, proving theorems in logic or mathematics. Others are not, because they can be done by all normal adults irrespective of educational background (and sometimes by non-human animals too), and typically involve no conscious control: seeing things in sunlight and shadows, finding a path through cluttered terrain, fitting pegs into holes, speaking one's own native tongue, and using one's common sense. Because it covers AI research dealing with both these classes of mental capacity, this definition is preferable to one describing AI as making computers do "things that would require intelligence if done by people." However, it presupposes that computers could do what minds can do, that they might really diagnose, advise, infer, and understand. One could avoid this problematic assumption (and also side-step questions about whether computers do things in the same way as we do) by defining AI instead as "the development of computers whose observable performance has features which in humans we would attribute to mental processes." This bland characterization would be acceptable to some AI workers, especially amongst those focusing on the production of technological tools for commercial purposes. But many others would favour a more controversial definition, seeing AI as the science of intelligence in general-or, more accurately, as the intellectual core of cognitive science. As such, its goal is to provide a systematic theory that can explain (and perhaps enable us to replicate) both the general categories of intentionality and the diverse psychological capacities grounded in them. (Boden, 1990b, pp. 1-2)
       Because the ability to store data somewhat corresponds to what we call memory in human beings, and because the ability to follow logical procedures somewhat corresponds to what we call reasoning in human beings, many members of the cult have concluded that what computers do somewhat corresponds to what we call thinking. It is no great difficulty to persuade the general public of that conclusion since computers process data very fast in small spaces well below the level of visibility; they do not look like other machines when they are at work. They seem to be running along as smoothly and silently as the brain does when it remembers and reasons and thinks. On the other hand, those who design and build computers know exactly how the machines are working down in the hidden depths of their semiconductors. Computers can be taken apart, scrutinized, and put back together. Their activities can be tracked, analyzed, measured, and thus clearly understood-which is far from possible with the brain. This gives rise to the tempting assumption on the part of the builders and designers that computers can tell us something about brains, indeed, that the computer can serve as a model of the mind, which then comes to be seen as some manner of information processing machine, and possibly not as good at the job as the machine. (Roszak, 1994, pp. xiv-xv)
       The inner workings of the human mind are far more intricate than the most complicated systems of modern technology. Researchers in the field of artificial intelligence have been attempting to develop programs that will enable computers to display intelligent behavior. Although this field has been an active one for more than thirty-five years and has had many notable successes, AI researchers still do not know how to create a program that matches human intelligence. No existing program can recall facts, solve problems, reason, learn, and process language with human facility. This lack of success has occurred not because computers are inferior to human brains but rather because we do not yet know in sufficient detail how intelligence is organized in the brain.

    A switchboard as defined in the National Electrical Code is a large single panel, frame, or assembly of panels on which are mounted, on the face or back or both switches, overcurrent and other protective devices, buses, and, usually, instruments.
    Switchboards are generally accessible from the rear as well as from the front and are not intended to be installed in cabinets.
    The types of switchboards, classified by basic features of construction, are as follows:
    1. Live-front vertical panels
    2. Dead-front boards
    3. Safety enclosed boards( metal-clad)

    [American electricians’ handbook]

    The switchboard plays an essential role in the availability of electric power, while meeting the needs of personal and property safety.

    Its definition, design and installation are based on precise rules; there is no place for improvisation.

    The IEC 61439 standard aims to better define " low-voltage switchgear and controlgear assemblies", ensuring that the specified performances are reached.

    It specifies in particular:

    > the responsibilities of each player, distinguishing those of the original equipment manufacturer - the organization that performed the original design and associated verification of an assembly in accordance with the standard, and of the assembly manufacturer - the organization taking responsibility for the finished assembly;

    > the design and verification rules, constituting a benchmark for product certification.

    All the component parts of the electrical switchboard are concerned by the IEC 61439 standard.

    Equipment produced in accordance with the requirements of this switchboard standard ensures the safety and reliability of the installation.

    A switchboard must comply with the requirements of standard IEC 61439-1 and 2 to guarantee the safety and reliability of the installation.

    Managers of installations, fully aware of the professional and legal liabilities weighing on their company and on themselves, demand a high level of safety for the electrical installation.

    What is more, the serious economic consequences of prolonged halts in production mean that the electrical switchboard must provide excellent continuity of service, whatever the operating conditions.

    НКУ играет главную роль в обеспечении электроэнергией, удовлетворяя при этом всем требованиям по безопасности людей и сохранности имущества.

    Выбор конструкции, проектирование и монтаж основаны на чётких правилах, не допускающих никакой импровизации.

    Требования к низковольтным комплектным устройствам распределения и управления сформулированы в стандарте МЭК 61439 (ГОСТ Р 51321. 1-2000).

    В частности, он определяет:

    > распределение ответственности между изготовителем НКУ - организацией, разработавшей конструкцию НКУ и проверившей его на соответствие требованиям стандарта, и сборщиком – организацией, выполнившей сборку НКУ;

    > конструкцию, технические характеристики, виды и методы испытаний НКУ.

    В стандарте МЭК 61439 (ГОСТ Р 51321. 1-2000) описываются все компоненты НКУ.

    Оборудование, изготовленное в соответствии с требованиями этого стандарта, обеспечивает безопасность и надежность электроустановки.

    Для того чтобы гарантировать безопасность эксплуатации и надежность работы электроустановки, распределительный щит должен соответствовать требованиям стандарта МЭК 61439-1 и 2.

    Лица, ответственные за электроустановки, должны быть полностью осведомлены о профессиональной и юридической ответственности, возложенной на их компанию и на них лично, за обеспечение высокого уровня безопасности эксплуатации этих электроустановок.

    Кроме того, поскольку длительные перерывы производства приводят к серьезным экономическим последствиям, электрический распределительный щит должен обеспечивать надежную и бесперебойную работу независимо от условий эксплуатации.
    [Перевод Интент]

     

    LV switchgear assemblies are undoubtedly the components of the electric installation more subject to the direct intervention of personnel (operations, maintenance, etc.) and for this reason users demand from them higher and higher safety requirements.

    The compliance of an assembly with the state of the art and therefore, presumptively, with the relevant technical Standard, cannot be based only on the fact that the components which constitute it comply with the state of the art and therefore, at least presumptively, with the relevant technical standards.

    In other words, the whole assembly must be designed, built and tested in compliance with the state of the art.

    Since the assemblies under consideration are low voltage equipment, their rated voltage shall not exceed 1000 Va.c. or 1500 Vd.c. As regards currents, neither upper nor lower limits are provided in the application field of this Standard.

    The Standard IEC 60439-1 states the construction, safety and maintenance requirements for low voltage switchgear and controlgear assemblies, without dealing with the functional aspects which remain a competence of the designer of the plant for which the assembly is intended.
    [ABB]

    Низковольтные комплектные устройства (НКУ), вне всякого сомнения, являются частями электроустановок, которые наиболее подвержены непосредственному вмешательству оперативного, обслуживающего и т. п. персонала. Вот почему требования потребителей к безопасности НКУ становятся все выше и выше.

    Соответствие НКУ современному положению дел и вследствие этого, гипотетически, соответствующим техническим стандартам, не может основываться только на том факте, что составляющие НКУ компоненты соответствуют современному состоянию дел и поэтому, по крайней мере, гипотетически, - соответствующим техническим стандартам

    Другими словами, НКУ должно быть разработано, изготовлено и испытано в соответствии с современными требованиями.

    Мы рассматриваем низковольтные комплектные устройства и это означает, что их номинальное напряжение не превышает 1000 В переменного тока или 1500 В постоянного тока. Что касается тока, то ни верхнее, ни нижнее значение стандартами, относящимися к данной области, не оговариваются

    Стандарт МЭК 60439-1 устанавливает требования к конструкции, безопасности и техническому обслуживанию низковольтных комплектных устройств без учета их функций, полагая, что функции НКУ являются компетенцией проектировщиков электроустановки, частью которых эти НКУ являются.
