Demetrios Magiros
Demetrios G. Magiros (Δημήτριος Γ. Μαγείρος, 19 December 1912, Euboea, Greece – 19 January 1982, Philadelphia, Pennsylvania) was a Greek-American mathematician, specializing in the stability of dynamical systems. Education and career Magiros did his undergraduate and graduate study at the University of Athens (National and Kapodistrian University of Athens), where he received his doctorate in pure mathematics in 1940. At the National Technical University of Athens he was appointed a lecturer in mechanics and geodesy and subsequently was promoted to professor of mathematics. During WW II he published no papers but in 1946 he published three papers on the catenary. In 1949 he went to the USA. There he studied applied mathematics at Brown University, at the Courant Institute of Mathematical Sciences, and at Massachusetts Institute of Technology (MIT).

Euboea
Euboea ( ; , ), also known by its modern spelling Evia ( ; , ), is the second-largest Greek island in area and population, after Crete, and the sixth largest island in the Mediterranean Sea. It is separated from Boeotia in mainland Greece by the narrow Euripus Strait (only at its narrowest point). In general outline it is a long and narrow island; it is about long, and varies in breadth from to . Its geographic orientation is from northwest to southeast, and it is traversed throughout its length by a mountain range, which forms part of the chain that bounds Thessaly on the east, and is continued south of Euboia in the lofty islands of Andros, Tinos and Mykonos. It forms most of the regional unit of Euboea, which also includes Skyros and a small area of the Greek mainland. Name Like most of the Greek islands, Euboea was known by other names in antiquity, such as ''Macris'' (Μάκρις) and ''Doliche'' (Δολίχη) from its elongated shape, or ''Ellopia'' (after El ...

General Electric Aerospace
GE Aerospace was a business group of General Electric. GE Aerospace made electronics and systems for the military and aerospace industries, like radar, secure communications equipment and military and commercial satellites. The majority of the group's business was in government and military applications. History During the late 1960s, GE Aerospace personnel developed the first realtime image generator. In 1991, the group had approximately 37,500 employees, most of whom were located in Florida and the New England and Middle Atlantic regions. The Delaware Valley alone accounted for roughly 17,600 employees. In 1993, the group was sold to Martin Marietta for over three billion dollars (U.S.), nearly doubling that company's revenue. In 1995, Martin Marietta merged with Lockheed to form Lockheed Martin. In 2010, the large Systems Integration ("The SI") division from GE Aerospace, with roots tracing back to the Apollo Program, was spun off to form The SI Organization Inc. ...

People From Euboea (regional Unit)
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Academic Staff Of The National Technical University Of Athens
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of tertiary education. The name traces back to Plato's school of philosophy, founded approximately 386 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and Skills, skill, north of Ancient Athens, Athens, Greece. The Royal Spanish Academy defines academy as scientific, literary or artistic society established with public authority and as a teaching establishment, public or private, of a professional, artistic, technical or simply practical nature. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the Gymnasium (ancient Greece), gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive Grove (nature), grove, hence the expression "the groves of Academe". In these gardens, the philos ...

Many robots are built to do jobs that are hazardous to people, such as finding survivors in unstable ruins, and exploring space, mines and shipwrecks. Others replace people in jobs that are boring, repetitive, or unpleasant, such as cleaning, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Control Theory
Control theory is a field of control engineering and applied mathematics that deals with the control system, control of dynamical systems in engineered processes and machines. The objective is to develop a model or algorithm governing the application of system inputs to drive the system to a desired state, while minimizing any ''delay'', ''overshoot'', or ''steady-state error'' and ensuring a level of control Stability theory, stability; often with the aim to achieve a degree of Optimal control, optimality. To do this, a controller with the requisite corrective behavior is required. This controller monitors the controlled process variable (PV), and compares it with the reference or Setpoint (control system), set point (SP). The difference between actual and desired value of the process variable, called the ''error'' signal, or SP-PV error, is applied as feedback to generate a control action to bring the controlled process variable to the same value as the set point.
