Bill Of Materials
A bill of materials or product structure (sometimes bill of material, BOM or associated list) is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts, and the quantities of each needed to manufacture an end product. A BOM may be used for communication between manufacturing partners or confined to a single manufacturing plant. A bill of materials is often tied to a production order whose issuance may generate reservations for components in the bill of materials that are in stock and requisitions for components that are not in stock. There are two types of bill materials. A BOM can define products as they are designed ( engineering bill of materials), as they are ordered (sales bill of materials), as they are built ( manufacturing bill of materials), or as they are maintained (service bill of materials). The different types depend on the business need and use for which they are intended. In process industries, the BOM is also known as the fo ...

RKM Code
The RKM code, also referred to as "letter and numeral code for resistance and capacitance values and tolerances", "letter and digit code for resistance and capacitance values and tolerances", or informally as "R notation" is a notation to specify resistor and capacitor values defined in the international standard IEC 60062 (formerly IEC 62) since 1952. It is also adopted by various other standards including DIN 40825 (1973), BS 1852 (1975), IS 8186 (1976) and EN 60062 (1993). The updated IEC 60062:2016, amended in 2019, comprises the most recent release of the standard. Overview Originally meant also as part marking code, this shorthand notation is widely used in electrical engineering to denote the values of resistors and capacitors in circuit diagrams and in the production of electronic circuits (for example in bills of material and in silk screens). This method avoids overlooking the decimal separator, which may not be rendered reliab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helmut-Schmidt-Universität
The Helmut Schmidt University (german: link=no, Helmut-Schmidt-Universität), located in Hamburg, Germany, is a German military educational establishment that was founded in 1973 at the initiative of the then-Federal Minister of Defence, Helmut Schmidt. Originally known as the "University of the Bundeswehr Hamburg" (''Universität der Bundeswehr''), its complete official name today is "Helmut-Schmidt-Universität/Universität der Bundeswehr Hamburg". Teaching first started in Autumn of 1973. It is one of two universities that were established by the Bundeswehr to train and educate its future and existing officers. In general, it is accessible only to officers and officer candidates of the Bundeswehr, hence its original name. However, since it started teaching, there have been cooperation agreements with allied countries, on the basis of which a handful of selected officers from these states have been able to study in Hamburg. Since 2002 there has been a small number of civilian st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CadSoft
EAGLE is a scriptable electronic design automation (EDA) application with schematic capture, printed circuit board (PCB) layout, auto-router and computer-aided manufacturing (CAM) features. EAGLE stands for Easily Applicable Graphical Layout Editor (german: Einfach Anzuwendender Grafischer Layout-Editor) and is developed by CadSoft Computer GmbH. The company was acquired by Autodesk Inc. in 2016. Features EAGLE contains a schematic editor, for designing circuit diagrams. Schematics are stored in files with .SCH extension, parts are defined in device libraries with .LBR extension. Parts can be placed on many sheets and connected together through ports. The PCB layout editor stores board files with the extension .BRD. It allows back-annotation to the schematic and auto-routing to automatically connect traces based on the connections defined in the schematic. EAGLE saves Gerber and PostScript layout files as well as Excellon and Sieb & Meyer drill files. These are standar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electronic Design Automation
Electronic design automation (EDA), also referred to as electronic computer-aided design (ECAD), is a category of software tools for designing electronic systems such as integrated circuits and printed circuit boards. The tools work together in a design flow that chip designers use to design and analyze entire semiconductor chips. Since a modern semiconductor chip can have billions of components, EDA tools are essential for their design; this article in particular describes EDA specifically with respect to integrated circuits (ICs). History Early days Prior to the development of EDA, integrated circuits were designed by hand and manually laid out. Some advanced shops used geometric software to generate tapes for a Gerber photoplotter, responsible for generating a monochromatic exposure image, but even those copied digital recordings of mechanically drawn components. The process was fundamentally graphic, with the translation from electronics to graphics done manu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carl Hanser Verlag
The Carl Hanser Verlag was founded in 1928 by Carl Hanser in Munich and is one of the few medium-sized publishing companies in the German-speaking area still owned by the founding family. History From the very beginning, the publishing house has been active in the two fields of fiction and literature, with fictional fiction being published from 1933 to 1946. The foundation stones of the publishing house were laid with the participation of the magazine "Betriebsstechnik", which was incorporated into the publishing house in 1933. The activities in the field of trade journals, with 21 publications, play an important role in addition to the literature and specialist books. The founder, Carl Hanser, withdrew from the active publishing management in 1976. In 1985 Carl Hanser died. Wolfgang Beisler, a grandson of Carl Hanser, became a member of the management in 1996. Michael Krüger was Managing Director of Carl Hanser Verlag until 2013 when Jo Lendle took over. In 1961, Carl Hanse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VDI Verlag
Verein Deutscher Ingenieure (VDI) (English: Association of German Engineers) is an organization of over 150,000 engineers and natural scientists. More than 12,000 honorary experts process the latest technical findings each year to promote the technology location. Established in 1856, it is the largest engineering association in Western Europe. Its role in Germany is comparable to that of the American Society of Civil Engineers (ASCE) in the United States or Engineers Australia (EA) in Australia, but includes broader field work. It is not a union, but promotes the advancement of technology and represents the interests of engineers and engineering businesses in Germany. History The organization was founded on May 12, 1856 by fellow researchers from the Academic Fraternity Hütte, in the small town of Alexisbad, with the first journal officially being released to the public in 1857. In 1866 the VDI helped establish the predecessor of Technischer Überwachungsverein, the Dampfkesselübe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SAP AG
Sap is a fluid transported in xylem cells (vessel elements or tracheids) or phloem sieve tube elements of a plant. These cells transport water and nutrients throughout the plant. Sap is distinct from latex, resin, or cell sap; it is a separate substance, separately produced, and with different components and functions. Insect honeydew is called sap, particularly when it falls from trees, but is only the remains of eaten sap and other plant parts. Types of sap Saps may be broadly divided into two types: xylem sap and phloem sap. Xylem sap Xylem sap (pronounced ) consists primarily of a watery solution of hormones, mineral elements and other nutrients. Transport of sap in xylem is characterized by movement from the roots toward the leaves. Over the past century, there has been some controversy regarding the mechanism of xylem sap transport; today, most plant scientists agree that the cohesion-tension theory best explains this process, but multiforce theorie ...

John Wiley & Sons
John Wiley & Sons, Inc., commonly known as Wiley (), is an American multinational publishing company founded in 1807 that focuses on academic publishing and instructional materials. The company produces books, journals, and encyclopedias, in print and electronically, as well as online products and services, training materials, and educational materials for undergraduate, graduate, and continuing education students. History The company was established in 1807 when Charles Wiley opened a print shop in Manhattan.
