Engineers , as practitioners of engineering , are professionals who invent , design , analyze, build and test machines , complex systems , structures , gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. The work of engineers forms the link between scientific discoveries and their subsequent applications to human and business needs and quality of life. It requires the exercise of original thought and judgement and the ability to supervise the technical and administrative work of others.

Many companies have tried to upgrade their quality, adopting programs that have been staples of the quality movement for a generation: cost of quality calculations, interfunctional teams, reliability engineering, or statistical quality control. Few companies, however, have learned to compete on quality. Part of the problem, of course, is that until Japanese and European competition intensified, not many companies seriously tried to make quality programs work even as they implemented them. But even if companies had implemented the traditional principles of quality control more rigorously, it is doubtful that U. To get a better grasp of the defensive character of traditional quality control, we should understand what the quality movement in the United States has achieved so far.

Engineers , as practitioners of engineering , are professionals who invent , design , analyze, build and test machines , complex systems , structures , gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. The work of engineers forms the link between scientific discoveries and their subsequent applications to human and business needs and quality of life. It requires the exercise of original thought and judgement and the ability to supervise the technical and administrative work of others.

Engineers develop new technological solutions. During the engineering design process , the responsibilities of the engineer may include defining problems, conducting and narrowing research, analyzing criteria, finding and analyzing solutions, and making decisions.

Much of an engineer's time is spent on researching, locating, applying, and transferring information. Engineers must weigh different design choices on their merits and choose the solution that best matches the requirements and needs. Their crucial and unique task is to identify, understand, and interpret the constraints on a design in order to produce a successful result. Engineers apply techniques of engineering analysis in testing, production, or maintenance.

Analytical engineers may supervise production in factories and elsewhere, determine the causes of a process failure, and test output to maintain quality. They also estimate the time and cost required to complete projects. Supervisory engineers are responsible for major components or entire projects.

Engineering analysis involves the application of scientific analytic principles and processes to reveal the properties and state of the system, device or mechanism under study.

Engineering analysis proceeds by separating the engineering design into the mechanisms of operation or failure, analyzing or estimating each component of the operation or failure mechanism in isolation, and recombining the components. They may analyze risk. Many engineers use computers to produce and analyze designs, to simulate and test how a machine, structure, or system operates, to generate specifications for parts, to monitor the quality of products, and to control the efficiency of processes.

Most engineers specialize in one or more engineering disciplines. Civil engineering, for example, includes structural and transportation engineering and materials engineering include ceramic, metallurgical, and polymer engineering. Mechanical engineering cuts across just about every discipline since its core essence is applied physics.

Engineers also may specialize in one industry, such as motor vehicles, or in one type of technology, such as turbines or semiconductor materials. Several recent studies have investigated how engineers spend their time; that is, the work tasks they perform and how their time is distributed among these. Research [8] [13] suggests that there are several key themes present in engineers' work: technical work i. Among other more detailed findings, a recent work sampling study [13] found that engineers spend Furthermore, there was considerable overlap between these different types of work, with engineers spending Engineering is also an information-intensive field, with research finding that engineers spend The time engineers spend engaged in such activities is also reflected in the competencies required in engineering roles.

There are many branches of engineering, each of which specializes in specific technologies and products. Typically, engineers will have deep knowledge in one area and basic knowledge in related areas.

For example, mechanical engineering curricula typically includes introductory courses in electrical engineering, computer science, materials science, metallurgy, mathematics, and software engineering. When developing a product, engineers typically work in interdisciplinary teams. For example, when building robots an engineering team will typically have at least three types of engineers.

A mechanical engineer would design the body and actuators. An electrical engineer would design the power systems, sensors, electronics, embedded software in electronics, and control circuitry. Finally, a software engineer would develop the software that makes the robot behave properly. Engineers that aspire to management engage in further study in business administration, project management and organizational or business psychology.

Often engineers move up the management hierarchy from managing projects, functional departments, divisions and eventually CEOs of a multi-national corporation. Agricultural technology incorporates such things as Robotics and Autonomous Vehicles. Engineers have obligations to the public, their clients, employers, and the profession.

Many engineering societies have established codes of practice and codes of ethics to guide members and inform the public at large. Each engineering discipline and professional society maintains a code of ethics, which the members pledge to uphold.

Depending on their specializations, engineers may also be governed by specific statute, whistleblowing, product liability laws, and often the principles of business ethics. Some graduates of engineering programs in North America may be recognized by the iron ring or Engineer's Ring , a ring made of iron or stainless steel that is worn on the little finger of the dominant hand. This tradition began in in Canada with The Ritual of the Calling of an Engineer , where the ring serves as a symbol and reminder of the engineer's obligations to the engineering profession.

In , the practice was adopted by several colleges in the United States including members of the Order of the Engineer. Most engineering programs involve a concentration of study in an engineering specialty, along with courses in both mathematics and the physical and life sciences. Many programs also include courses in general engineering and applied accounting.

A design course, often accompanied by a computer or laboratory class or both, is part of the curriculum of most programs. Often, general courses not directly related to engineering, such as those in the social sciences or humanities, also are required. Accreditation is the process by which engineering programs are evaluated by an external body to determine if applicable standards are met. The Washington Accord serves as an international accreditation agreement for academic engineering degrees, recognizing the substantial equivalency in the standards set by many major national engineering bodies.

In the United States, post-secondary degree programs in engineering are accredited by the Accreditation Board for Engineering and Technology. In many countries, engineering tasks such as the design of bridges, electric power plants, industrial equipment, machine design and chemical plants, must be approved by a licensed professional engineer.

Most commonly titled professional engineer is a license to practice and is indicated with the use of post-nominal letters ; PE or P. The practice of engineering in the UK is not a regulated profession but the control of the titles of chartered engineer CEng and incorporated engineer IEng is regulated.

These titles are protected by law and are subject to strict requirements defined by the Engineering Council UK. The title CEng is in use in much of the Commonwealth. Many skilled and semi-skilled trades and engineering technicians in the UK call themselves engineers. A growing movement in the UK is to legally protect the title 'Engineer' so that only professional engineers can use it; a petition [18] was started to further this cause.

In the United States, engineering is a regulated profession whose practice and practitioners are licensed and governed by law. Each state tests and licenses professional engineers. Currently, most states do not license by specific engineering discipline, but rather provide generalized licensure, and trust engineers to use professional judgment regarding their individual competencies; this is the favoured approach of the professional societies.

Despite this, at least one of the examinations required by most states is actually focused on a particular discipline; candidates for licensure typically choose the category of examination which comes closest to their respective expertise. In the United States, an "industrial exemption" allows businesses to employ employees and call them an "engineer", as long as such individuals are under the direct supervision and control of the business entity and function internally related to manufacturing manufactured parts related to the business entity, or work internally within an exempt organization.

Such person does not have the final authority to approve, or the ultimate responsibility for, engineering designs, plans, or specifications that are to be incorporated into fixed works, systems, or facilities on the property of others or made available to the public. These individuals are prohibited from offering engineering services directly to the public or other businesses, or engage in practice of engineering unless the business entity is registered with the state's board of engineering, and the practice is carried on or supervised directly only by engineers licensed to engage in the practice of engineering.

A few states require a graduate MS in engineering to sit for the exams as further learning. After seven years of working after graduation, two years of responsibility for significant engineering work, continuous professional development, some highly qualified PEs are able to become International Professional Engineers Int PE. These engineers must meet the highest level of professional competencies and this is a peer reviewed process. Once the IntPE title is awarded, the engineer can gain easier admission to national registers of a number of members jurisdictions for international practice.

In Canada, engineering is a self-regulated profession. The profession in each province is governed by its own engineering association. For instance, in the Province of British Columbia an engineering graduate with four or more years of post graduate experience in an engineering-related field and passing exams in ethics and law will need to be registered by the Association for Professional Engineers and Geoscientists APEGBC [22] in order to become a Professional Engineer and be granted the professional designation of P.

Eng allowing one to practice engineering. In Continental Europe , Latin America, Turkey, and elsewhere the title is limited by law to people with an engineering degree and the use of the title by others is illegal. In Italy, the title is limited to people who hold an engineering degree, have passed a professional qualification examination Esame di Stato and are enrolled in the register of the local branch of National Associations of Engineers a public body.

In Portugal, professional engineer titles and accredited engineering degrees are regulated and certified by the Ordem dos Engenheiros. In the Czech Republic, the title "engineer" Ing. In Greece, the academic title of "Diploma Engineer" is awarded after completion of the five-year engineering study course and the title of "Certified Engineer" is awarded after completion of the four-year course of engineering studies at a Technological Educational Institute TEI.

British school children in the s were brought up with stirring tales of "the Victorian Engineers", chief among whom were Brunel , Stephenson , Telford , and their contemporaries. In the UK, "engineering" has more recently been erroneously styled as an industrial sector consisting of employers and employees loosely termed "engineers" who include tradespeople.

However, knowledgeable practitioners reserve the term "engineer" to describe a university-educated professional of ingenuity represented by the Chartered or Incorporated Engineer qualifications. Also, many UK skilled and semi-skilled tradespeople falsely style themselves as "engineers".

This has created confusion in the eyes of some members of the public in understanding what professional engineers actually do, from fixing car engines, television sets and refrigerators technicians, handymen to designing and managing the development of aircraft, spacecraft, power stations, infrastructure and other complex technological systems engineers.

Engineering schools which were created during the French revolution have a special reputation among the French people, as they helped to make the transition from a mostly agricultural country of late 18th century to the industrially developed France of the 19th century.

However, after the Haby reform and a string of further reforms Modernization plans of French universities , several engineering schools were created which can be accessed with relatively lower competition. Engineers are less highlighted in current French economy as industry provides less than a quarter of the GDP.

In Italy, only people who hold a formal engineering qualification of at least a Bachelor's degree are permitted to describe themselves as an engineer. So much so that people holding such qualifications are entitled to use the pre-nominal title of "Ingegnere" or "Ingegnera" if female - in both cases often abbreviated to "Ing.

Spain follows the Italian convention of engineers using the pre-nominal title, in this case "ingeniero" or "ingeniera" if female. Like Italy, it is usually abbreviated to "Ing. As of [update] , thirty two countries in Europe including nearly all 27 countries of the EU now recognise the title of 'European Engineer' which permits the use of the pre-nominal title of "EUR ING" always fully capitalised. Each country sets its own precise qualification requirement for the use of the title though they are all broadly equivalent.

Holding the requisite qualification does not afford automatic entitlement. The title has to be applied for and the appropriate fee paid. The holder is entitled to use the title in their passport. EUR INGs are allowed to describe themselves as engineers and practise as such in any of the 32 participating countries including those where the title of engineer is regulated by law. In the United States, the practice of professional engineering is highly regulated and the title "professional engineer" is legally protected, meaning that it is unlawful to use it to offer engineering services to the public unless permission, certification or other official endorsement is specifically granted by that state through a professional engineering license.

In Canada, engineering is a regulated profession whose practice and practitioners are licensed and governed by law. Licensed professional engineers are referred to as P.

Product design engineering is an exciting industry that continually evolves alongside technology, product advancements, the demand for quicker turnaround times, unique and personalised products, and environmentally friendly supply chains and production. It's about understanding product requirements and functionality, questioning existing ways of doing things and seeing opportunities to change things for the better. Product design engineering blends a more technical engineering focus such as mechanics, electronics, maths, engineering calculations of a products' design with design principles, user experience, and technology to create new functional products or develop existing ones that can then be sold in competitive markets. This is integrated with manufacturing processes, CAD, rapid prototyping and digital prototyping technologies, software and practical skills to turn the design into reality which is fundamental to global market success and requires not only customer appeal, aesthetics and brand awareness but also consistent and correct functionality, superior quality and fitness for purposes all at a competitive price. As well as design classes which allow you to develop your appreciation of feasible design and production options such as:.

A3 report: The A3 report, developed by Toyota, is a problem-solving tool to define or clarify problems, suggest solutions, and record the results of improvement activities. The report is written on ledger-sized paper 11 x 17 inches and includes text, pictures, diagrams, and charts broken into different sections, each clearly labeled and arranged in a logical flow to produce a desired outcome for a proposed process. Acceptance number: The maximum number of defects or defectives allowable in a sampling lot for the lot to be acceptable. Acceptance quality limit AQL : In a continuing series of lots, a quality level that, for the purpose of sampling inspection, is the limit of a satisfactory process average. Acceptance sampling: Inspection of a sample from a lot to decide whether to accept that lot.

Терпение Стратмора иссякло. Он взорвался: - Сьюзан, выслушай. Я вызвал тебя сюда, потому что мне нужен союзник, а не следователь. Сегодня у меня было ужасное утро. Вчера вечером я скачал файл Танкадо и провел у принтера несколько часов, ожидая, когда ТРАНСТЕКСТ его расколет.

ГЛАВА 105 Огненный шар, рвущийся наверх сквозь миллионы силиконовых чипов, производил ни на что не похожий звук. Треск лесного пожара, вой торнадо, шипение горячего гейзера… все они слились в гуле дрожащего корпуса машины. Это было дыхание дьявола, ищущее выхода и вырывающееся из закрытой пещеры. Стратмор так и остался стоять на коленях, парализованный ужасающим, неуклонно приближающимся звуком. Самый дорогой компьютер в мире на его глазах превращался в восьмиэтажный ад.

 Извините, сэр… Бринкерхофф уже шел к двери, но Мидж точно прилипла к месту. - Я с вами попрощался, мисс Милкен, - холодно сказал Фонтейн.

Весь антракт он просидел с ручкой в руке, ломая голову над посланием из одиннадцати букв: HL FKZC VD LDS В конце концов, когда уже гасли огни перед началом второго акта, его осенило. Шифруя послание, Сьюзан просто заменила в нем каждую букву на предшествующую ей алфавите. Для расшифровки Беккеру нужно было всего лишь подставить вместо имеющихся букв те, что следовали непосредственно за ними: А превращалось в В, В - в С и так далее. Беккер быстро проделал это со всеми буквами.

 Мы терпим бедствие! - крикнул техник.  - Все линии устремились к центру. С левого экрана в камеру неотрывно смотрели Дэвид и агенты Смит и Колиандер. На ВР последняя стенка напоминала тонюсенькую пленку.

Мгновение спустя, как в одном из самых страшных детских кошмаров, перед ней возникло чье-то лицо. Зеленоватое, оно было похоже на призрак. Это было лицо демона, черты которого деформировали черные тени. Сьюзан отпрянула и попыталась бежать, но призрак схватил ее за руку.

 Вы из полиции. Беккер покачал головой. Панк пристально смотрел на .

Беккер слушал как завороженный. Учитель превратился в ученика. Однажды вечером на университетском представлении Щелкунчика Сьюзан предложила Дэвиду вскрыть шифр, который можно было отнести к числу базовых.

Там происходит что-то очень серьезное. - Мидж.  - Он постарался ее успокоить, входя вслед за ней в комнату заседаний к закрытому жалюзи окну.  - Пусть директор разбирается .
