WideArea Traffic: The Failure of Poisson Modeling
 IEEE/ACM TRANSACTIONS ON NETWORKING
, 1995
"... Network arrivals are often modeled as Poisson processes for analytic simplicity, even though a number of traffic studies have shown that packet interarrivals are not exponentially distributed. We evaluate 24 widearea traces, investigating a number of widearea TCP arrival processes (session and con ..."

Some simple effective approximations to the 2Poisson model for probabilistic weighted retrieval
 In Proceedings of SIGIR’94
, 1994
"... The 2–Poisson model for term frequencies is used to suggest ways of incorporating certain variables in probabilistic models for information retrieval. The variables concerned are withindocument term frequency, document length, and withinquery term frequency. Simple weighting functions are develope ..."

depremselliğini araştırmak için GutenbergRichter magnitüdfrekans ilişkisi, sismik risk ve tekrarlanma peryodu hesaplanmıştır. Çözümlemede 1900 öncesi tarihsel dönem (I0 ≥ 5.0 şiddet değerleri MS ≥ 4.4 magnitüdlerine karşılık gelmektedir) ve 2007’ye kadar olan aletsel dönem (MS ≥ 4.0) deprem verileri kullanılmıştır. İnceleme alanı bölgenin sismotektonik özellikleri, levha tektoniği modelleri ve jeolojisi dikkate alınarak 15 altbölgeye ayrılmıştır ve tüm hesaplamalar bu altbölgeler için ayrı ayrı yapılmıştır. Elde edilen sonuçlara gore, hesaplanan magnitüdfrekans ilişkisindeki a ve b değerleri 3.10±0.245.29±0.52 and 0.39±0.030.73±0.08 aralığında bulunmuştur. En yüksek b değerleri 7. (Gökova KörfeziMuğlaGölhisar) ve 1. (İzmirSakız adası) altbölgeler için, en düşük bdeğerleri ise 15. (Antakya) ve 8. (Bodrumİstanköy) altbölgeler için bulunmuştur. Son olarak a ve b değerlerinden yararlanarak yapılan sismik risk ve tekrarlanma peryodları hesaplamaları en yüksek risklerin ve en kısa tekrarlanma peryodlarının en düşük b değerlerine sahip 15 ve 8.altbölgelerde olduğunu göstermiştir.
Poisson Model of Spike Generation
, 2000
"... ring rate to be very large at particular moments in time so that the probability of firing would then be arbitrarily close to 1. Certain features of neuronal firing, however, violate the independent spike hypothesis. Following the generation of an action potential, there is an interval of time know ..."

Below, I present ways of extending the Poisson model to account for refractoriness and bursting. 1 Probability and Random Processes A random variable is a number assigned to every outcome
The Bivariate 2Poisson model for IR
"... Harter’s 2Poisson model of Information Retrieval is a univariate model of the raw term frequencies, that does not condition the probabilities on document length [2]. A bivariate stochastic model is thus introduced to extend Harter’s 2Poisson model, by conditioning the term frequencies of the docum ..."

A Language Modeling Approach to Information Retrieval
, 1998
"... Models of document indexing and document retrieval have been extensively studied. The integration of these two classes of models has been the goal of several researchers but it is a very difficult problem. We argue that much of the reason for this is the lack of an adequate indexing model. This sugg ..."

A Compositional Approach to Performance Modelling

The size and complexity of many modern systems result in large, complex models. A compositional approach decomposes the system into subsystems that are smaller and more ea ..."

Poisson Surface Reconstruction
, 2006
"... We show that surface reconstruction from oriented points can be cast as a spatial Poisson problem. This Poisson formulation considers all the points at once, without resorting to heuristic spatial partitioning or blending, and is therefore highly resilient to data noise. Unlike radial basis function ..."
