' Necking ', in engineering or materials science, is a mode of tensile deformation where relatively large amounts of strain localize disproportionately in a small region of the material.

Necking results from an instability during tensile deformation when a material's cross-sectional area decreases by a greater proportion than the material strain hardens.

Through his father, Alfred Nobel was a descendant of the Swedish scientist Olaus Rudbeck ( 1630 – 1702 ), and in his turn the boy was interested in engineering, particularly explosives, learning the basic principles from his father at a young age.

The term Building design professional ( or Design professional ), by contrast, is a much broader term including professionals who practice independently under an alternate profession, such as engineering professionals, or those who assist in the practice architecture under the supervision of a licensed architect, such as architectural technologists and intern architects.

AIX was the first operating system to utilize journaling file systems, and IBM has continuously enhanced the software with features like processor, disk and network virtualization, dynamic hardware resource allocation ( including fractional processor units ), and reliability engineering ported from its mainframe designs.

The term shmoo has also entered the lexicon, defining highly technical concepts in no less than four separate fields of science, including the variations shmooing ( a microbiological term for the " budding " process in yeast reproduction ), and shmoo plot ( a technical term in the field of electrical engineering ).

In simpler term, Biotechnology is the research and development in the laboratory that involves bioinformatics for exploration, extraction, exploitation and production from any living organisms and any source of biomass by means of biochemical engineering where high value-added products could be planned ( reproduced by Biosynthesis, for example ), fore-casted, formulated, developed, manufactured and marketed for the purpose of sustainable operations ( for the return from bottomless initial investment on R & D ) and gaining durable patents rights ( for exclusives rights for sales, and prior to this to receive national and international approval from the results on animal experiment and human experiment, especially on the pharmaceutical branch of biotechnology to prevent any undetected side-effects on safety concerns by using the products ), for more about the biotechnology industry, see.

The notation aspect of the Booch method has now been superseded by the Unified Modeling Language ( UML ), which features graphical elements from the Booch method along with elements from the object-modeling technique ( OMT ) and object-oriented software engineering ( OOSE ).

Biologics / Biopharmaceuticals ( e. g., vaccines, stored blood product ), genetic engineering, and various agricultural applications are some major classes of biotechnology.

They may also feature extensive collaborative efforts with programs in other fields ( such as the University's Medical School or other engineering divisions ), owing again to the interdisciplinary nature of BME.

and Ph. D. programs will typically require applicants to have an undergraduate degree in BME, or another engineering discipline ( plus certain life science coursework ), or life science ( plus certain engineering coursework ).

Some classic examples of these types of tasks are multimedia applications ( images, video, and sound ), as well as many types of scientific and engineering tasks.

* Cone penetration test ( CPT ), an in situ testing method used to determine the geotechnical engineering properties of soils

They favor a more holistic approach based on the 4 ' E's ; education ( of everyone involved ), encouragement ( to apply the education ), enforcement ( to protect the rights of others ), and engineering ( to facilitate travel while respecting every person's equal right to do so ).

Chemical engineering is the branch of engineering that deals with physical science ( e. g., chemistry and physics ), and life sciences ( e. g., biology, microbiology and biochemistry ) with mathematics and economics, to the process of converting raw materials or chemicals into more useful or valuable forms.

The American Institute of Chemical Engineers ( AIChE ), established in 1908, played a key role in making chemical engineering considered an independent science, and unit operations central to chemical engineering.

Along with other novel concepts, such process systems engineering ( PSE ), a " second paradigm " was defined.

* Campaign for Science and Engineering ( CaSE ), a non-profit organization which promotes science and engineering research in the UK

* Computer-aided software engineering ( CASE ), use of computers to assist in the software development life cycle

recommend to the Congress from time to time authorization for construction and operation, or for participation in the construction and operation, of a demonstration plant for any process which he determines, on the basis of subsections ( A ) and ( B ) above, has great promise of accomplishing the purposes of this Act, such recommendation to be accompanied by a report on the size, location, and cost of the proposed plant and the engineering and economic details with respect thereto ; ;

* Provide engineering and technical expertise on all matters related to medical technology, especially in the process of planning, review, evaluation, and specification of medical equipment.

In their various roles, they form a " bridge " between the primary designers and the end-users, by combining the perspectives of being both 1 ) close to the point-of-use, while 2 ) trained in product and process engineering.

Within software engineering, programming ( the implementation ) is regarded as one phase in a software development process.

Within chemical engineering, two broad subgroups include 1 ) design, manufacture, and operation of plants and machinery in industrial chemical and related processes (" chemical process engineers "); and 2 ) development of new or adapted substances for products ranging from foods and beverages to cosmetics to cleaners to pharmaceutical ingredients, among many other products (" chemical product engineers ").

Transport phenomena gave an analytical approach to chemical engineering while PSE focused on its synthetic elements, such as control system and process design.

The engineering margin that was reserved for manufacturing tolerance has been used for data capacity instead, leaving no tolerance for manufacturing ; for these discs to be truly compliant with the Orange Book standard, the manufacturing process must be perfect.

The field of control within chemical engineering is often known as process control.

When a binary mixture is evaporated and the other component, e. g. a salt, has zero partial pressure for practical purposes, the process is simpler and is called evaporation in engineering.

Design is the creation of a plan or convention for the construction of an object or a system ( as in architectural blueprints, engineering drawing, business process, circuit diagrams and sewing patterns ).

Schools of engineering, as well as schools of architecture, business, education, law, and medicine, are all centrally concerned with the process of design.

In engineering, design is a component of the engineering process.

A design may also be a mere plan that does not include a production or engineering process, although a working knowledge of such processes is usually expected of designers.

The process and concept of ecosystem engineering has also been called niche construction.

The ecosystem engineering concept has stimulated a new appreciation for the influence that organisms have on the ecosystem and evolutionary process.

* Systems engineering process

In the sciences and engineering, the process of decomposing a function into simpler pieces is often called Fourier analysis, while the operation of rebuilding the function from these pieces is known as Fourier synthesis.

A variety of classification schemes have been proposed that order genetically modified organisms based on the nature of introduced genotypical changes rather than the process of genetic engineering.

The process of genetically engineering animals is a slow, tedious, and expensive process.
