Drive shaftA drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load.
IP addressAn Internet Protocol address (IP address) is a numerical label such as 192.0.2.1 that is connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: network interface identification, and location addressing. Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number. However, because of the growth of the Internet and the depletion of available IPv4 addresses, a new version of IP (IPv6), using 128 bits for the IP address, was standardized in 1998.
Plasticity (physics)In physics and materials science, plasticity (also known as plastic deformation) is the ability of a solid material to undergo permanent deformation, a non-reversible change of shape in response to applied forces. For example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes occur within the material itself. In engineering, the transition from elastic behavior to plastic behavior is known as yielding. Plastic deformation is observed in most materials, particularly metals, soils, rocks, concrete, and foams.
QazvinQazvin (kæzˈviːn; قزوین, ɢæzˈviːn, also Romanized as Qazvīn, Qazwin, Kazvin, Kasvin, Caspin, Casbin, Casbeen, or Ghazvin) is a city in the Central District of Qazvin County, Qazvin province, Iran, and serves as capital of the district, county, and province. It is the largest city in Qazvin province. Qazvin was a capital of the Safavid dynasty for over forty years (1555–1598) and nowadays is known as the calligraphy capital of Iran. It is famous for its traditional confectioneries (like Baghlava), carpet patterns, poets, political newspaper and Pahlavi influence on its accent.
MadrasaMadrasa (məˈdræsə, also US-rɑːs-, UKˈmædrɑːsə; Arabic: مدرسة mædˈræ.sæ, ˈmad.ra.sa, pl. مدارس, ALA) is the Arabic word for any type of educational institution, secular or religious (of any religion), whether for elementary education or higher learning. The word is variously transliterated Madrasah arifah, medresa, madrassa, madraza, medrese, etc. In countries outside the Arab world, the word usually refers to a specific type of religious school or college for the study of the religion of Islam, though this may not be the only subject studied.
Voice over IPVoice over Internet Protocol (VoIP), also called IP telephony, is a method and group of technologies for voice calls, the delivery of voice communication sessions over Internet Protocol (IP) networks, such as the Internet. The broader terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of voice and other communications services (fax, SMS, voice messaging) over the Internet, rather than via the public switched telephone network (PSTN), also known as plain old telephone service (POTS).
Constraint logic programmingConstraint logic programming is a form of constraint programming, in which logic programming is extended to include concepts from constraint satisfaction. A constraint logic program is a logic program that contains constraints in the body of clauses. An example of a clause including a constraint is . In this clause, is a constraint; A(X,Y), B(X), and C(Y) are literals as in regular logic programming. This clause states one condition under which the statement A(X,Y) holds: X+Y is greater than zero and both B(X) and C(Y) are true.
AxeAn axe (æks sometimes ax in American English; see spelling differences) is an implement that has been used for millennia to shape, split, and cut wood, to harvest timber, as a weapon, and as a ceremonial or heraldic symbol. The axe has many forms and specialised uses but generally consists of an axe head with a handle, also called a haft or a helve. Before the modern axe, the stone-age hand axe without a handle was used from 1.5 million years BP. Hafted axes (those with a handle) date only from 6,000 BC.
