Conny Palm (6979247547)
Conrad "Conny" Rudolf Agaton Palm (May 31, 1907 – December 27, 1951) was a Swedish electrical engineer and statistician, known for several contributions to teletraffic engineering and queueing theory. Rolf B. HaugenThe life and work of Conny Palm – some personal comments and experiencesfrom ''Telektronikk'' (Telenor research journal), 2(3):50–55, 1995 Education and career Palm enrolled at the School of Electrical Engineering at the Royal Institute of Technology in Stockholm in 1925, being awarded his M.Sc. (1940) and Ph.D (1943) on a dissertation entitled ''Intensitätsschwankungen im Fernsprechverkehr'' (Intensity Fluctuations in Telephone Traffic). Palm's work was also joint with L. M. Ericsson, cooperating with Christian Jacobæus. He attended Harald Cramér's queueing theory group, met William Feller (1937). Later, Palm was in the Swedish Board for Computing Machinery (''Matematikmaskinnämnden''), where he led the project that developed the first Swedish computer, ...

Stockholm
Stockholm () is the Capital city, capital and List of urban areas in Sweden by population, most populous city of Sweden as well as the List of urban areas in the Nordic countries, largest urban area in the Nordic countries.

Telecommunications
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as code ...

Academic Staff Of The KTH Royal Institute Of Technology
An academy ( Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. 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 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, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Queueing Theorists
Queue areas are places in which people queue ( first-come, first-served) for goods or services. Such a group of people is known as a ''queue'' ( British usage) or ''line'' (American usage), and the people are said to be waiting or standing ''in a queue'' or ''in line'', respectively. (In the New York City area, the phrase ''on line'' is often used in place of ''in line''.) Occasionally, both the British and American terms are combined to form the term "queue line". Examples include checking out groceries or other goods that have been collected in a self service shop, in a shop without self-service, at an ATM, at a ticket desk, a city bus, or in a taxi stand. Queueing is a phenomenon in a number of fields, and has been extensively analysed in the study of queueing theory. In economics, queueing is seen as one way to ration scarce goods and services. Types Physical History The first written description of people standing in line is found in an 1837 book, '' The Fren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Palm–Khintchine Theorem
In probability theory, the Palm–Khintchine theorem, the work of Conny Palm and Aleksandr Khinchin, expresses that a large number of renewal processes, not necessarily Poissonian, when combined ("superimposed") will have Poissonian properties. It is used to generalise the behaviour of users or clients in queuing theory. It is also used in dependability and reliability modelling of computing and telecommunications. Theorem According to Heyman and Sobel (2003), the theorem states that the superposition of a large number of independent equilibrium renewal processes, each with a finite intensity, behaves asymptotically like a Poisson process: Let \, i=1,2,\ldots, m be independent renewal processes and \ be the superposition of these processes. Denote by X_ the time between the first and the second renewal epochs in process j. Define N_(t) the jth counting process, F_(t)=P(X_\leq t) and \lambda_=1/(E((X_)). If the following assumptions hold 1) For all sufficiently large m: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
