Random Vibration
In mechanical engineering, random vibration is motion which is non-deterministic, meaning that future behavior cannot be precisely predicted. The randomness is a characteristic of the excitation or input, not the mode shapes or natural frequencies. Some common examples include an automobile riding on a rough road, wave height on the water, or the load induced on an airplane wing during flight. Structural response to random vibration is usually treated using statistical or probabilistic approaches. Mathematically, random vibration is characterized as an ergodic and stationary process. A measurement of the acceleration spectral density (ASD) is the usual way to specify random vibration. The root mean square acceleration (Grms) is the square root of the area under the ASD curve in the frequency domain. The Grms value is typically used to express the overall energy of a particular random vibration event and is a statistical value used in mechanical engineering for structural design a ...

Functionally Graded Material
In materials science Functionally Graded Materials (FGMs) may be characterized by the variation in composition and structure gradually over volume, resulting in corresponding changes in the properties of the material. The materials can be designed for specific function and applications. Various approaches based on the bulk (particulate processing), preform processing, layer processing and melt processing are used to fabricate the functionally graded materials. History The concept of FGM was first considered in Japan in 1984 during a space plane project, where a combination of materials used would serve the purpose of a thermal barrier capable of withstanding a surface temperature of 2000 K and a temperature gradient of 1000 K across a 10 mm section. In recent years this concept has become more popular in Europe, particularly in Germany. A transregional collaborative research center (SFB Transregio) is funded since 2006 in order to exploit the potential of grading monomateri ...

Worcester Reed Warner Medal
Worcester Reed Warner (May 16, 1846 – June 25, 1929) was an American mechanical engineer, entrepreneur, manager, astronomer, and philanthropist. With Ambrose Swasey he cofounded the Warner & Swasey Company. Biography Life and career Warner was born near Cummington, Massachusetts.p. 11 He met Swasey at the Exeter Machine Works. On the completion of their apprenticeship in 1870, both entered the employ of Pratt & Whitney in Hartford, Connecticut. In 1880 he co-founded a business to manufacture machines with Ambrose Swasey. The firm, Warner & Swasey, was initially located in Chicago but soon moved to Cleveland.p. 19 Worcester Warner would design the 36-inch refracting telescope installed at Lick Observatory in 1888. He later built telescopes that were used in Canada and Argentina. Further activities Warner was a charter member of the American Society of Mechanical Engineers, and from 1897 to 1898 he served as the 16th president of ASME. (Ambrose Swasey would later serve as ...

Composite Material
A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. Typical engineered composite materials include: *Reinforced concrete and masonry *Composite wood such as plywood *Reinforced plastics, such as fibre-reinforced polymer or fiberglass *Ceramic matrix composites ( composite ceramic and metal matrices) *Metal matrix composites *and other advanced composite materials There are various reasons where new material can be favoured. Typical examples include materials which are less expensive, lighter, stronger or more durable when compared with commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nanotechnology
Nanotechnology, also shortened to nanotech, is the use of matter on an atomic, molecular, and supramolecular scale for industrial purposes. The earliest, widespread description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defined nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter which occur below the given size threshold. It is therefore common to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kutaisi
Kutaisi (, ka, ქუთაისი ) is one of the oldest continuously inhabited cities in the world and the third-most populous city in Georgia, traditionally, second in importance, after the capital city of Tbilisi. Situated west of Tbilisi, on the Rioni River, it is the capital of the western region of Imereti. Historically one of the major cities of Georgia, it served as political center of Colchis in the Middle Ages as capital of the Kingdom of Abkhazia and Kingdom of Georgia and later as the capital of the Kingdom of Imereti. From October 2012 to December 2018, Kutaisi was the seat of the Parliament of Georgia as an effort to decentralise the Georgian government. History Archaeological evidence indicates that the city functioned as the capital of the Colchis in the sixth to fifth centuries BC. It is believed that, in ''Argonautica'', a Greek epic poem about Jason and the Argonauts and their journey to Colchis, author Apollonius Rhodius considered Kutaisi their final d ...

Boca Raton, Florida
Boca Raton ( ; es, Boca Ratón, link=no, ) is a city in Palm Beach County, Florida, United States.

University Of Palermo
The University of Palermo ( it, Università degli Studi di Palermo) is a university located in Palermo, Italy, and founded in 1806. It is organized in 12 Faculties. History The University of Palermo was officially founded in 1806, although its earliest roots date back to 1498 when medicine and law were taught there. A little later in history, from the second half of the 16th century from their seat at the Collegio Massimo al Cassero, the Jesuit Fathers granted degrees in Theology and Philosophy - subjects in which they had been masters for over 200 years. In 1767 they were expelled from the kingdom by King Ferdinand I, until 37 years later, when they returned to take their seat - which in the meantime had been turned into the Regia Accademia. At this time, the same King Ferdinand decided to grant a good seat to the Accademia, moving its location to the Convent of the Teatini Fathers next to the Church of St. Giuseppe. After the unification of Italy in 1860, the University ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
